1 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
3 Fast save_excursion_save and save_excursion_restore.
4 * lisp.h (struct Lisp_Excursion): New data type.
5 (PVEC_EXCURSION): New pseudovector type.
6 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
7 to deal with it. Adjust comments.
8 (init_marker, attach_marker): New prototype.
9 (unchain_marker): Adjust prototype.
10 * marker.c (attach_marker): Change to global.
11 (init_marker): New function.
12 * alloc.c (Fmake_marker, build_marker): Use it.
13 (build_marker): More easserts.

18 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
20 Fix export of symbols to GDB (Bug#12036).
21 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
22 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
23 emacs.c, as this is a more-suitable home. Had this been done earlier
24 the fix for 12036 would have avoided some of the problems noted in
25 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
26 would have been more obvious.
27 * emacs.c: Do not include <verify.h>; no longer needed.
28 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
29 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
30 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
31 Remove; now done in lisp.h.
32 * lisp.h (PUBLISH_TO_GDB): New macro.
33 (GCTYPEBITS, USE_LSB_TAG, CHECK_LISP_OBJECT_TYPE, enum pvec_type)
34 (DATA_SEG_BITS): Use it.
35 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
36 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
37 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
38 not be usable in #if. This simplifies things.
40 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
42 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
44 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
46 Simplify export of symbols to GDB (Bug#12036).
47 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
48 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
49 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
50 Adjust to changes in lisp.h and emacs.c, by using
51 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
52 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
53 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
54 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
55 instead of gdb_valbits.
56 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
57 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
58 instead of gdb_array_mark_flag.
59 (xboolvector): Get size from $->size, not $->header.size.
60 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
61 (xreload, hook-run, hookpost-run): Remove.
62 * emacs.c: Include <verify.h>.
63 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
64 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
65 Remove.
66 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
67 (gdb_USE_LSB_TAG): New enum constants.
68 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
69 Also define these as enum constants, so they're visible to GDB.
70 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
71 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
72 as constants, so they're visible to GDB.
73 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
74 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
75 Now enum constants, not macros, so they're visible to GDB.
76 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
77 more convenient now. All uses changed.
78 (VALMASK) [USE_LSB_TAG]: Also define in this case.
79 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
81 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

88 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
89 add argument, tune behavior, and adjust all callers.
91 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
93 Use typedef for EMACS_INT, EMACS_UINT.
94 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
95 than macros. This simplifies debugging in the usual case, since
96 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
97 and it allows expressions involving EMACS_INT casts.
98 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
100 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>

112 Adjust buffer text indirection counters at the end of Fkill_buffer.
113 * buffer.c (Fkill_buffer): Adjust indirection counters when the
114 buffer is definitely dead. This should really fix an issue reported
115 by Christoph Scholtes again. (Bug#12007).
116 (init_buffer_once): Initialize indirection counters of
117 buffer_defaults and buffer_local_symbols (for sanity and safety).
119 2012-07-24 Eli Zaretskii <eliz@gnu.org>
121 * xdisp.c (init_iterator): Don't compute dimensions of truncation
122 and continuation glyphs on tooltip frames, leave them at zero.
123 Avoids continued lines in tooltips. (Bug#11832)
125 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
127 Simplify copy_overlay.
128 * buffer.c (copy_overlay): Simplify. Use build_marker.
129 * lisp.h (struct Lisp_Overlay): Restore comment with minor tweaks.
131 2012-07-23 Eli Zaretskii <eliz@gnu.org>

134 or invalid. (Bug#12025)
136 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
137 it signals an error when a tooltip frame is being created.
139 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>

150 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
152 Swap buffer text indirection counters in Fbuffer_swap_text.
153 * buffer.c (Fbuffer_swap_text): Swap indirections too.
154 This avoids crash reported by Christoph Scholtes at
155 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
157 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
159 * nsmenu.m (Popdown_data): New struct.
160 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
161 free Popdown_data.
162 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
163 (initWithContentRect): Make imgView and contentView non-static
164 and autorelease them. Also autorelease img and matrix (Bug#12005).

180 (set_marker_both, set_marker_restricted_both): Use live_buffer.
182 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
184 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
185 as it's limited by the amount of memory, not by INT_MAX.
187 2012-07-21 Eli Zaretskii <eliz@gnu.org>
189 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
190 in special-event-map. See the discussion at
191 http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00417.html
192 for the reasons.
194 * w32menu.c (add_menu_item): Cast to ULONG_PTR when assigning

325 2012-07-18 Paul Eggert <eggert@cs.ucla.edu>
327 * alloc.c (Fmake_bool_vector): Fix off-by-8 bug
328 when invoking (make-bool-vector N t) and N is a positive
329 multiple of 8 -- the last 8 bits were mistakenly cleared.
331 Remove some struct layout assumptions in bool vectors.
332 * alloc.c (bool_header_size): New constant.

929 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
930 which are not functions. All uses rewritten to use:
931 (make_emacs_time): New function.
932 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
933 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
934 not functions. All uses rewritten to use the following, respectively:
935 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
936 (add_emacs_time, sub_emacs_time): New functions.
937 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.

963 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
964 * nsterm.m (ns_term_init):
965 Avoid the need for strncpy, by using build_string or
966 make_unibyte_string directly. Use dtoastr, not snprintf.
967 * process.c (Fmake_network_process): Diagnose service names that
968 are too long, rather than silently truncating them or creating
969 non-null-terminated names.
970 (Fnetwork_interface_info): Likewise, for interface names.
971 * sysdep.c (system_process_attributes) [GNU_LINUX]:
972 Prefer sprintf to strncat.

979 Clarify fallback case.
981 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
983 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
984 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
985 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
986 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
987 where argument type is known to be a Lisp_Cons.

999 Optimize pure C strings initialization.
1000 * lisp.h (make_pure_string): Fix prototype.
1001 (build_pure_c_string): New function, defined as static inline. This
1002 provides a better opportunity to optimize away calls to strlen when
1003 the function is called with compile-time constant argument.
1004 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
1005 argument, adjust users accordingly. Use build_pure_c_string where
1006 appropriate.
1007 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
1008 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
1009 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
1011 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
1013 Avoid calls to strlen in miscellaneous functions.
1014 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
1015 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
1016 * lread.c (openp): Likewise.
1018 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
1020 Avoid calls to strlen in path processing functions.
1021 * fileio.c (file_name_as_directory): Add comment. Change to add
1022 srclen argument and return the length of result. Adjust users
1023 accordingly.
1024 (directory_file_name): Fix comment. Change to add srclen argument,

1036 * s/gnu.h (DATA_START): Move definitions to configure.
1038 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
1039 We include usg5-4-common.h, which defines them both.
1041 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
1042 O_RDONLY already includes it).
1044 Stop ns builds setting the EMACSLOADPATH environment variable.
1045 * nsterm.m (ns_load_path): Rename from ns_init_paths.
1046 Now it does not set EMACSLOADPATH, just returns the load-path string.
1047 * nsterm.h: Update accordingly.
1048 * lread.c [HAVE_NS]: Include nsterm.h.
1049 (init_lread) [HAVE_NS]: Use ns_load_path.

1052 2012-07-09 Glenn Morris <rgm@gnu.org>
1054 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
1055 since the included bsd-common.h does so.
1057 Stop ns builds setting the EMACSPATH environment variable.
1058 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
1059 (ns_init_paths): Do not set EMACSPATH.
1060 * nsterm.h (ns_exec_path): Add it.
1061 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
1062 Use ns_exec_path.
1064 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
1066 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
1068 * process.c (wait_reading_process_output): 'waitchannels' was unset
1069 when read_kbd || !NILP (wait_for_cell); fix this.
1071 Add GCC-style 'const' attribute to functions that can use it.
1072 * character.h (char_resolve_modifier_mask):
1073 * keyboard.h (make_ctrl_char):
1074 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
1075 (init_character_once, next_almost_prime, init_fns, init_image)

1083 Add decls with ATTRIBUTE_CONST.
1085 Minor improvements to make_formatted_string.
1086 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
1087 where int is good enough, as vsprintf returns an int.
1088 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
1090 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
1092 Use make_formatted_string to avoid double length calculation.
1093 * lisp.h (make_formatted_string): New prototype.
1094 * alloc.c (make_formatted_string): New function.
1095 * buffer.c (Fgenerate_new_buffer_name): Use it.

1115 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
1117 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
1119 Move marker debugging code under MARKER_DEBUG.
1120 * marker.c (MARKER_DEBUG): Move marker debugging code under
1121 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
1122 for bootstrap with --enable-checking (~3x slowdown reported
1123 by Juanma Barranquero <lekktu@gmail.com>).
1124 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
1126 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
1128 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
1129 See <http://bugs.gnu.org/11825#29>.
1131 2012-07-08 Eli Zaretskii <eliz@gnu.org>
1133 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
1134 has no font, use the frame's font. (Bug#11813)
1135 (display_line): Add commentary about displaying truncation glyphs
1136 on GUI frames.
1137 (produce_special_glyphs): Move here from term.c.
1139 * term.c (produce_special_glyphs): Move to xdisp.c.
1141 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
1142 section.
1144 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
1146 * xdisp.c (display_line): Avoid warning about implicit declaration
1147 of FRAME_FONT.
1149 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
1151 * lisp.h: Remove empty conditional.
1153 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
1155 * lread.c (load_path_check): Now static.
1157 Fix some minor --with-ns problems found by static checking.
1158 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
1159 (x_set_font) [!HAVE_X_WINDOWS]:
1160 * image.c (xpm_load_image) [HAVE_NS]:
1161 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
1162 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
1163 Remove unused local.
1164 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
1165 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
1166 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
1167 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
1168 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
1169 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
1170 Fix pointer signedness problem.
1171 * xfaces.c (FRAME_X_FONT_TABLE):
1172 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
1174 2012-07-07 Glenn Morris <rgm@gnu.org>
1176 * lread.c (load_path_check): New function, split from init_lread.
1177 (init_lread): Reorganize. Motivation:
1178 If EMACSLOADPATH is set, check/warn about that rather than the
1179 defaults, which we are not going to use. Hence we can remove
1180 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
1181 Don't warn if site-lisp directories are missing.
1182 If not installed, start from a blank load-path, since
1183 PATH_LOADSEARCH refers to the eventual installation directories.
1185 2012-07-07 Eli Zaretskii <eliz@gnu.org>
1187 Support truncation and continuation glyphs on GUI frames, when
1188 fringes are disabled. (Bug#11832)
1189 * xdisp.c (init_iterator): Get dimensions of truncation and
1190 continuation glyphs even if on GUI frames. Adjust
1191 it->last_visible_x on GUI frames when the left or right fringes,
1192 or both, are absent.
1193 (start_display, move_it_in_display_line_to): Handle the case of a
1194 GUI frame without a fringe to display continuation or truncation
1195 glyphs.
1196 (insert_left_trunc_glyphs): Support GUI frames: make sure
1197 truncation glyphs overwrite enough glyphs from the current line to
1198 have sufficient space in pixels.
1199 (display_line): Support truncation and continuation glyphs on GUI
1200 frames. If some spare pixels are left on the line after inserting
1201 the truncation glyphs, fill that space with a stretch glyph of a
1202 suitably computed width.
1204 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
1205 produce_glyphs, to support GUI sessions.
1207 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
1209 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
1211 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
1213 Do not require float-time's arg to fit in time_t (Bug#11825).
1214 This works better on hosts where time_t is unsigned, and where
1215 float-time is applied to the (negative) difference between two times.
1216 * editfns.c (decode_time_components): Last arg is now double *,
1217 not int *, and means to store all the result as a double, without
1218 worrying about whether the seconds part fits in time_t.
1219 All callers changed.
1220 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
1221 All callers changed.
1222 (Ffloat_time): Do not fail merely because the specified time falls
1223 outside of time_t range.
1225 2012-07-07 Glenn Morris <rgm@gnu.org>
1227 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
1228 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
1229 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
1231 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
1233 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
1234 Update dependencies.
1236 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
1238 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1240 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
1241 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
1242 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
1243 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
1244 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
1245 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
1247 * xfont.c (compare_font_names): Redo to omit the need for casts.
1249 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
1251 * xfns.c (Fx_change_window_property): Doc fix.
1252 * w32fns.c (Fx_change_window_property): Doc fix.
1254 * w32fns.c (Fx_window_property): Accept the same arguments as the
1255 X Windows version. Doc fix.
1256 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
1258 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
1259 Eli Zaretskii <eliz@gnu.org>
1261 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
1262 Windows-specific code from nt/config.nt moved here.
1263 Obsolete settings removed.
1265 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1267 * process.c: Avoid unnecessary calls to gettime.
1268 (wait_reading_process_output): Don't get the time of day
1269 when gobbling data immediately and not waiting, as there's no need
1270 for it in that case. This removes a FIXME.
1272 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
1274 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
1275 is defined (Bug#11768).
1277 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1279 Fix marker debugging code.
1280 * marker.c (byte_char_debug_check): Do not perform the check
1281 if buffer is not multibyte.
1282 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
1283 Call byte_char_debug_check with correct arguments.
1285 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1287 Compile marker debugging code only if ENABLE_CHECKING is defined.
1288 * marker.c (byte_char_debug_check, count_markers):
1289 Use only if ENABLE_CHECKING is defined.
1290 (byte_debug_flag): Remove.
1291 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
1292 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
1294 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1296 Avoid code repetition in marker-related functions.
1297 * marker.c (attach_marker): New function.
1298 (Fset_marker, set_marker_restricted, set_marker_both)
1299 (set_marker_restricted_both): Use it.
1300 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
1301 Consistently rename charno to charpos.
1302 (marker_position): Add eassert.
1303 (marker_byte_position): Convert to eassert.
1305 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1307 Simplify list operations in unchain_overlay and unchain_marker.

1322 * window.c (save_window_save): Likewise.
1324 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1326 Do not use Fdelete_overlay in delete_all_overlays
1327 to avoid redundant calls to unchain_overlay.
1328 * buffer.c (drop_overlay): New function.
1329 (delete_all_overlays, Fdelete_overlay): Use it.
1330 * minibuf.c (get_minibuffer): Fix comment.
1332 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1334 Port to OpenBSD 5.1 amd64.
1335 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
1336 This is needed for OpenBSD, and should be harmless on all BSD systems.
1337 Also, include <sys/sysctl.h>, as it should be available on all
1338 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
1339 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
1340 use p_pid member, not kp_proc.pid.
1342 2012-07-06 Glenn Morris <rgm@gnu.org>
1344 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
1346 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
1348 More xmalloc and related cleanup.

1357 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
1358 * xterm.c:
1359 Omit needless casts involving void * pointers and allocation.
1360 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
1361 as the former is more robust if P's type is changed.
1362 Prefer xzalloc to xmalloc + memset 0.
1363 Simplify malloc-or-realloc to realloc.
1364 Don't worry about xmalloc returning a null pointer.
1365 Prefer xstrdup to xmalloc + strcpy.
1366 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
1367 growing it.
1368 * keyboard.c (apply_modifiers_uncached): Prefer local array to
1369 alloca of a constant.
1371 2012-07-05 Eli Zaretskii <eliz@gnu.org>
1373 * xdisp.c (display_line): Fix horizontal pixel coordinates when
1374 hscroll is larger than the line width. Fixes long and futile
1375 looping inside extend_face_to_end_of_line (on a TTY) producing
1376 glyphs that are not needed and thrown away.
1378 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
1380 * marker.c (set_marker_restricted_both): Simplify by using
1381 clip_to_bounds.
1383 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
1385 * editfns.c (region_limit): Simplify by using clip_to_bounds.
1387 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
1389 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
1390 not defined (Bug#11768).
1391 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
1392 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
1393 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
1394 followed by gtk_box_set_homogeneous (Bug#11768).
1395 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
1396 (update_theme_scrollbar_width, xg_create_scroll_bar):
1397 Use gtk_scrollbar_new (Bug#11768).
1398 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
1399 (is_box_type): New function (Bug#11768).
1400 (xg_tool_item_stale_p): Call is_box_type.
1401 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
1402 with default display (Bug#11768).
1404 2012-07-05 Eli Zaretskii <eliz@gnu.org>
1406 * xdisp.c (window_hscroll_limited): New function.
1407 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
1408 coordinates when window's hscroll is set to insanely large
1409 values. (Bug#11857)
1411 2012-07-05 Juanma Barranquero <lekktu@gmail.com>

1472 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
1474 * fileio.c (time_error_value): Check the right error number.
1475 Problem reported by Troels Nielsen in
1476 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
1478 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1480 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
1481 This should be fixed in a better way; see Eli Zaretskii in
1482 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
1483 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
1485 * fileio.c (time_error_value): Rename from special_mtime.
1486 The old name's problems were noted by Eli Zaretskii in
1487 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
1489 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
1490 This variable's comment says Emacs needs at least one GDB-visible
1491 symbol of type enum pvec_type, to work around GDB problems.
1492 The symbol's value doesn't matter.
1494 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
1495 that causes compilation to fail on pre-C99 compilers.
1497 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
1499 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
1500 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
1502 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
1504 * buffer.c (init_buffer_once): Fix initialization of
1505 headers for buffer_defaults and buffer_local_symbols.
1506 Reported by Juanma Barranquero <lekktu@gmail.com>.
1508 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
1510 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
1511 * lisp.h (enum pvec_type): Use fewer bits.
1512 (PSEUDOVECTOR_SIZE_BITS): New constant.
1513 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
1514 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
1515 change in pvec_type.
1516 (PSEUDOVECTOR_TYPEP): New macro.
1517 (TYPED_PSEUDOVECTORP): Use it.
1518 * fns.c (internal_equal): Adapt code to extract pvectype.
1519 * emacs.c (gdb_pvec_type): Update type.
1520 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
1521 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
1522 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
1523 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
1524 (sweep_vectors): Use it. Use local var `total_bytes' instead of
1525 abusing vector->header.next.nbytes.
1526 (live_vector_p): Use PVEC_TYPE.
1527 (mark_object): Adapt code to extract pvectype. Use switch.
1529 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1531 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
1532 Tighten new eassert a bit.
1534 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
1536 Fix compilation with --enable-gcc-warnings and -O1
1537 optimization level.
1538 * doprnt.c (doprnt): Change type of tem to int, initialize
1539 to avoid compiler warning. Add eassert.
1540 * search.c (simple_search): Initialize match_byte to avoid
1541 compiler warning. Add eassert.
1543 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1545 Avoid weird behavior with large horizontal scrolls.
1546 Without this change, for example, large hscroll values would
1547 mess up Emacs's display on Fedora 15 x86, presumably due to
1548 overflows in int calculations in the display code.
1549 Also, if buffers had long lines, Emacs would freeze.
1550 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
1551 (set_window_hscroll): New function, containing the old guts of
1552 Fset_window_hscroll. Return the clipped value.
1553 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
1554 This avoids the need to check against PTRDIFF_MAX.
1556 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
1558 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
1560 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
1562 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1564 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
1565 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
1566 since GCC 4.4.6 issues a bogus warning for them.
1568 Fix bugs in file timestamp newness comparisons.
1569 * fileio.c (Ffile_newer_than_file_p):
1570 * lread.c (Fload): Use full timestamp resolution of files,
1571 not just the 1-second resolution, so that files that are only
1572 slightly newer still count as newer.
1573 * fileio.c (Ffile_newer_than_file_p): Don't assume file
1574 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
1576 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
1578 * fileio.c: Improve handling of file time marker. (Bug#11852)
1579 (special_mtime): New function.
1580 (Finsert_file_contents, Fverify_visited_file_modtime):
1581 Use it to set special mtime values consistently.
1583 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
1585 * fileio.c (Finsert_file_contents): Properly handle st_mtime
1586 marker for non-existing file. (Bug#11852)
1588 2012-07-03 Glenn Morris <rgm@gnu.org>
1590 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
1591 and did not make it into globals.h).
1593 2012-07-03 Tom Tromey <tromey@redhat.com>
1595 * window.c (Fset_window_margins, Fset_window_fringes)
1596 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
1597 * textprop.c (Fprevious_property_change): No longer static.

1599 * process.c (Fget_process, Fprocess_datagram_address): No longer
1600 static.
1601 * keymap.c (Flookup_key, Fcopy_keymap): No longer static.
1602 * keyboard.c (Fcommand_execute): No longer static.
1603 Remove EXFUN.

1620 * intervals.h: Remove EXFUNs.
1621 * fontset.h: Remove EXFUN.
1622 * font.h: Remove EXFUNs.
1623 * dosfns.c (system_process_attributes): Remove EXFUN.
1624 * keymap.h: Remove EXFUNs.
1625 * lisp.h: Remove EXFUNs.
1626 * w32term.h: Remove EXFUNs.
1627 * window.h: Remove EXFUNs.
1628 * xsettings.h: Remove EXFUN.
1629 * xterm.h: Remove EXFUN.
1631 2012-07-03 Glenn Morris <rgm@gnu.org>
1633 * lisp.h (Frandom): Make it visible to C.
1634 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
1635 buffer for invisible buffers. (Bug#1229)
1637 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
1639 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
1640 values which aren't power of 2.
1641 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro. Verify
1642 it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
1643 accordingly.
1645 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
1647 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
1649 * alloc.c (mark_object): Revert part of last patch to use `switch'.
1651 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
1653 * alloc.c (allocate_vector_block): Remove redundant
1654 calls to mallopt if DOUG_LEA_MALLOC is defined.
1655 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
1656 avoid calls to mallopt if zero_vector is returned.
1658 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
1660 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
1661 is enabled, avoid dereferencing NULL current_sblock if
1662 running undumped.
1664 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
1666 Cleanup basic buffer management.
1667 * buffer.h (struct buffer): Change layout to use generic vector
1668 marking code. Fix some comments. Change type of 'clip_changed'
1669 to bitfield. Remove unused #ifndef old.
1670 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
1671 (GET_OVERLAYS_AT): Fix indentation.
1672 (for_each_per_buffer_object_at): New macro.
1673 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)

1681 (mark_object): Use it. Adjust marking of misc objects
1682 and related comments.
1684 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
1686 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
1687 wrapper that is not needed because the wrapped code is a no-op (zero
1688 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
1689 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
1691 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
1693 * alloc.c (mark_buffer): Simplify. Remove prototype.
1694 (mark_object): Add comment. Reorganize marking of vector-like
1695 objects. Use CHECK_LIVE for all vector-like objects except buffers
1696 and subroutines when GC_CHECK_MARKED_OBJECTS is defined. Avoid
1697 redundant calls to mark_vectorlike for bool vectors.
1699 2012-06-30 Glenn Morris <rgm@gnu.org>
1701 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
1703 * epaths.in (PATH_SITELOADSEARCH): New.
1704 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
1705 This is rather than relying on --enable-locallisppath elements
1706 having "site-lisp" in their names. (Bug#10208#25, 11658)
1708 2012-06-30 Eli Zaretskii <eliz@gnu.org>
1710 * w32proc.c (sys_select): Accept and ignore one more argument.
1712 * w32.c (emacs_gnutls_pull): Call select with one more argument.
1714 * sysselect.h [DOS_NT]: Don't include sys/select.h.
1715 (pselect) [!MS_DOS]: Redirect to sys_select.
1717 * sysdep.c: Don't include dos.h and dosfns.h.
1719 * process.c (sys_select):
1720 * msdos.c (sys_select): Accept one more argument and ignore it.
1722 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
1723 adapt data types and code to that.
1725 * dosfns.c:
1726 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
1727 which clashes with the gnulib function of the same name.
1729 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
1731 * font.c (font_style_to_value, font_style_symbolic)
1732 (font_prop_validate_style): Add type checks for values in
1733 font_style_table.
1735 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
1736 argument.
1737 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
1738 uses.
1740 2012-06-29 Eli Zaretskii <eliz@gnu.org>
1742 * xdisp.c (try_window_id): Undo last change.
1744 * w32.c (getwd): Adjust commentary about startup_dir.
1745 (init_environment): Always call sys_access, even in non-MSVC
1746 builds. Don't chdir to the directory of the Emacs executable.
1747 This undoes code from 1997 which was justified by the need to
1748 "avoid conflicts when removing and renaming directories". But its
1749 downside was that every relative file name was being interpreted
1750 relative to the directory of the Emacs executable, which can never
1751 be TRT. In particular, it broke sys_access when called with
1752 relative file names.
1753 (sys_access): Map GetLastError to errno.
1755 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
1757 * window.h (struct window): Change type of 'fringes_outside_margins'
1758 to bitfield. Fix comment. Adjust users accordingly.

1760 Adjust comment.
1761 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
1762 to ptrdiff_t.
1764 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
1766 * gnutls.c (emacs_gnutls_handshake):
1767 Add QUIT to make the loop interruptible.
1769 2012-06-29 Glenn Morris <rgm@gnu.org>
1771 * charset.c (init_charset): Make lack of etc/charsets fatal.
1773 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
1775 * editfns.c (region_limit): Fix type mismatch.
1777 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
1779 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
1780 undefined. Convert from xassert to eassert.
1781 * nsmenu.m: Convert from xassert to eassert.
1782 * nsterm.m: Likewise.
1784 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
1786 * editfns.c (region_limit): Clip to narrowing (bug#11770).
1788 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
1790 Avoid integer overflow on scroll-left and scroll-right.
1791 * window.c (HSCROLL_MAX): New macro.
1792 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
1793 overflow when requested scroll falls outside ptrdiff_t range.
1795 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
1797 * window.h (struct window): Change type of 'hscroll',
1798 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
1799 'last_modified' and 'last_overlay_modified' to EMACS_INT.
1800 Adjust users accordingly.
1801 * xdisp.c (try_cursor_movement): Replace type check with eassert.
1802 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
1803 from EMACS_INT to ptrdiff_t.
1804 (make_window): Omit redundant initialization.
1806 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
1808 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
1810 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
1812 * window.h (struct window): Change type of 'use_time' and
1813 'sequence_number' from Lisp_Object to int.
1814 * frame.c (make_frame): Adjust users accordingly.
1815 * print.c (print_object): Likewise.
1816 * window.c (select_window, Fwindow_use_time, make_parent_window)
1817 (make_window): Likewise.

1945 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
1947 Use sprintf return value instead of invoking strlen on result.
1948 In the old days this wasn't portable, since some sprintf
1949 implementations returned char *. But they died out years ago and
1950 Emacs already assumes sprintf returns int.
1951 Similarly for float_to_string.
1952 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

1959 * xfns.c (syms_of_xfns):
1960 Use sprintf or float_to_string result to avoid need to call strlen.
1961 * data.c (Fnumber_to_string):
1962 Use make_unibyte_string, since the string must be ASCII.
1963 * lisp.h, print.c (float_to_string): Now returns int length.
1964 * term.c (produce_glyphless_glyph):
1965 Use sprintf result rather than recomputing it.
1967 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
1968 * Makefile.in (ALL_CFLAGS):
1969 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

1991 2012-06-25 Paul Eggert <eggert@cs.ucla.edu>
1993 * gtkutil.c (get_utf8_string): Remove redundant assignment.
1994 sprintf already null-terminates its output.
1996 * xfns.c (x_window): Remove redundant cast.
1998 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
2000 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
2001 `const char *' to `char *' to avoid compiler warning.
2003 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
2005 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
2006 instead of truncating it to 63 (admittedly a generous limit).
2008 * process.c: Fix spelling and caps in comments.

2061 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
2063 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
2064 * lisp.h (WAIT_READING_MAX): New macro.
2065 * dispnew.c (Fsleep_for, sit_for):
2066 * keyboard.c (kbd_buffer_get_event):
2067 * process.c (Faccept_process_output):
2068 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
2069 This improves on the previous patch, which introduced a bug
2070 when time_t is unsigned and as wide as intmax_t.
2071 See <http://bugs.gnu.org/9000#51>.
2073 2012-06-23 Eli Zaretskii <eliz@gnu.org>
2075 * dispnew.c (sit_for, Fsleep_for):
2076 * keyboard.c (kbd_buffer_get_event):

2091 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
2092 All uses changed.
2093 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
2094 not make_lisp_timeval, when the argument is of type EMACS_TIME.
2096 2012-06-23 Eli Zaretskii <eliz@gnu.org>
2098 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
2099 last argument of make_unibyte_string.
2101 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
2102 language ID in the event parameters.
2104 * w32term.c (w32_read_socket): Put the new keyboard codepage into
2105 event.code, not the obscure "character set ID".
2107 2012-06-23 Chong Yidong <cyd@gnu.org>
2109 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.
2111 2012-06-23 Eli Zaretskii <eliz@gnu.org>

2128 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
2129 Privately reported by Herbert J. Skuhra.
2130 [__FreeBSD__]: Remove "*/" typo after "#include".

2132 (TIMEVAL) [__FreeBSD__]: Now a static function rather than a macro.
2133 (TIMEVAL, system_process_attributes) [__FreeBSD__]:
2134 Don't assume EMACS_TIME and struct timeval are the same type.
2136 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
2138 Support higher-resolution time stamps (Bug#9000).
2139 The time stamps are only nanosecond-resolution at the C level,
2140 since that's the best that any real-world system supports now.
2141 But they are picosecond-resolution at the Lisp level, as that's
2142 easy, and leaves room for future OS improvements.
2144 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
2145 (LIBES): Use it.
2147 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
2148 Don't get current time unless it's needed.
2150 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
2151 now provides it if it's absent.
2152 (start_atimer): Port to higher-res time stamps.
2153 Check for time stamp overflow. Don't get current time more
2154 often than is needed.
2156 * buffer.h (struct buffer): Buffer modtime now has high resolution.
2157 Include systime.h, not time.h.
2158 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
2160 * dired.c: Include stat-time.h.
2161 (Ffile-attributes): File times now have higher resolution.

2164 (struct image): Timestamp now has higher resolution.
2166 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
2167 has at least microseconds now. All uses removed.
2168 (update_frame, update_single_window, update_window, update_frame_1)
2169 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
2171 * editfns.c (time_overflow): Now extern.
2172 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
2173 (float-time, Fformat_time_string, Fcurrent_time_string)
2174 (Fcurrent_time_zone): Accept and generate higher-resolution
2175 time stamps.
2176 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
2177 (decode_time_components, lisp_seconds_argument): New functions.
2178 (make_time): Now static.
2179 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
2180 Report an error if the time is invalid, rather than having the caller
2181 do that.
2183 * fileio.c: Include <stat-time.h>
2184 (Fcopy_file): Copy higher-resolution time stamps.
2185 Prefer to set the time stamp via a file descriptor if that works.
2186 (Fset_file_times, Finsert_file_contents, Fwrite_region)
2187 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
2188 (Fvisited_file_modtime, Fset_visited_file_modtime):
2189 Support higher-resolution time stamps.
2191 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
2193 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
2195 * image.c (prepare_image_for_display, clear_image_cache)
2196 (lookup_image): Port to higer-resolution time stamps.
2198 * keyboard.c (start_polling, bind_polling_period):
2199 Check for time stamp overflow.
2200 (read_char, kbd_buffer_get_event, timer_start_idle)
2201 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
2202 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
2203 Port to higher-resolution time stamps. Do not assume time_t is signed.
2204 (decode_timer): New function. Timers are now vectors of length 9,
2205 not 8, to accommodate the picosecond component.
2206 (timer_check_2): Use it.
2208 * nsterm.m (select_timeout, timeval_subtract): Remove.
2209 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
2210 as they're a bit more accurate and handle overflow better.
2211 (ns_select): Change prototype to be compatible with pselect.
2212 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
2213 * nsterm.h (ns_select): Adjust prototype.
2215 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
2216 us-resolution time stamps.
2217 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
2219 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
2221 * lisp.h (time_overflow): New decl.
2222 (wait_reading_process_output): First arg is now intmax_t, not int,
2223 to accommodate larger waits.
2225 * process.h (struct Lisp_Process.read_output_delay):
2226 Now counts nanoseconds, not microseconds.
2227 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
2228 EMACS_HAS_USECS.
2229 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
2230 (wait_reading_process_output):
2231 Port to ns-resolution time stamps.
2232 (Faccept_process_output, wait_reading_process_output):
2233 Check for time stamp overflow. Do not assume time_t is signed.
2234 (select_wrapper): Remove; we now use pselect.
2235 (Fprocess_attributes): Now generates ns-resolution time stamps.
2237 * sysdep.c: Include utimens.h. Don't include utime.h
2238 or worry about struct utimbuf; gnulib does that for us now.
2239 (gettimeofday): Remove; gnulib provides a substitute.
2240 (make_timeval): New function.
2241 (set_file_times): Now sets ns-resolution time stamps.
2242 New arg FD; all uses changed.
2243 (time_from_jiffies, ltime_from_jiffies, get_up_time)
2244 (system_process_attributes):
2245 Now returns ns-resolution time stamp. All uses changed.
2246 Check for time stamp overflow.
2248 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
2249 provides a substitute now.
2251 * systime.h: Include timespec.h rather than sys/time.h and time.h,
2252 since it guarantees struct timespec.
2253 (EMACS_TIME): Now struct timespec, so that we can support
2254 ns-resolution time stamps.
2255 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
2256 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
2257 (EMACS_USECS): Remove.
2258 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
2259 so multiply the arg by 1000 before storing it.
2260 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
2261 New macros.
2262 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
2263 Port to ns-resolution time stamps.
2264 (EMACS_TIME_NEG_P): Remove; replaced by....
2265 (EMACS_TIME_SIGN): New macro.
2266 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
2267 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
2268 (set_file_times, make_time, lisp_time_argument): Adjust signature.
2269 (make_timeval, make_lisp_time, decode_time_components): New decls.
2270 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
2271 that it mishandled time_t overflow. You can't compare by subtracting!
2272 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
2273 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
2275 * term.c: Include <sys/time.h>.
2276 (timeval_to_Time): New function, for proper overflow wraparound.
2277 (term_mouse_position, term_mouse_click): Use it.
2279 * undo.c (record_first_change): Support higher-resolution time stamps
2280 in the undo buffer.
2281 (Fprimitive_undo): Use them when restoring time stamps.
2283 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
2284 (w32_get_internal_run_time):
2285 Port to higher-resolution Emacs time stamps.
2286 (ltime): Now accepts single 64-bit integer, as that's more convenient
2287 for callers.
2289 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
2291 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
2292 for compatibility with pselect. Support ns-resolution time stamps.
2294 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
2296 * xselect.c (wait_for_property_change, x_get_foreign_selection):
2297 Check for time stamp overflow, and support ns-resolution time stamps.

2301 (timeval_subtract): Remove; no longer needed.
2302 (XTflash, XTring_bell, x_wait_for_event):

2309 2012-06-22 Eli Zaretskii <eliz@gnu.org>
2311 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
2312 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
2313 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
2314 staticidx goes up to 1597 out of 1600 = 0x640.)
2316 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
2318 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
2319 Otherwise, the umask might be mistakenly 0 while handling input signals.

2329 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
2330 access to `contents' member of Lisp_Vector objects with AREF and ASET
2331 where appropriate.
2333 2012-06-19 Chong Yidong <cyd@gnu.org>
2335 * frame.c (delete_frame): When selecting a frame on a different
2336 text terminal, do not alter the terminal's top-frame.

2339 frame's selected window and its terminal's top-frame.
2340 (unwind_format_mode_line): Restore them.
2341 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
2342 Callers changed.
2343 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
2344 since tty frames can be explicitly named.
2345 (prepare_menu_bars): Likewise.
2347 * term.c (Ftty_top_frame): New function.
2349 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
2351 Port byte-code-meter to modern targets.
2352 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
2353 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
2354 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
2355 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
2356 (METER_1, METER_2): Simplify.
2358 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
2360 * data.c (Fdefalias): Return `symbol' (bug#11686).
2362 2012-06-18 Martin Rudalics <rudalics@gmx.at>
2364 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
2365 gets killed during executing of this function (Bug#11665).
2366 Try to always return Qt when the buffer has been actually killed.
2367 (Vkill_buffer_query_functions): In doc-string say that functions
2368 run by this hook should not change the current buffer.
2370 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
2372 Fix recently-introduced process.c problems found by static checking.

2390 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
2392 * lisp.h (eassert): Assume C89 or later.
2393 This removes the need for CHECK.
2394 (CHECK): Remove. Its comments about always evaluating its
2395 argument were confusing, as 'eassert' typically does not evaluate
2396 its argument.
2398 * coding.c (produce_chars): Use ptrdiff_t, not int.
2400 * xterm.c (x_draw_underwave): Check for integer overflow.
2401 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.
2403 2012-06-17 Jan Djärv <jan.h.d@swipnet.se>
2405 * nsterm.m (x_free_frame_resources): Move xfree so freed memory isn't

2423 (x_draw_glyph_string): Use it.
2425 2012-06-16 Juanma Barranquero <lekktu@gmail.com>
2427 * makefile.w32-in ($(BLD)/emacs.$(O), $(BLD)/fringe.$(O))

2492 2012-06-16 Eli Zaretskii <eliz@gnu.org>
2494 * xdisp.c (set_cursor_from_row): Don't dereference glyphs_end.
2495 If all the glyphs of the glyph row came from strings, and we have no
2496 cursor positioning clues, put the cursor on the first glyph of the
2497 row.
2498 (handle_face_prop): Use chunk-relative overlay string index when
2499 indexing into it->string_overlays array. (Bug#11653)
2500 (set_cursor_from_row): Use the leftmost glyph as GLYPH_BEFORE, not

2512 (Fdelete_window_internal): Don't access frame's mouse highlight
2513 info of the initial frame. (Bug#11677)
2515 2012-06-14 Paul Eggert <eggert@cs.ucla.edu>
2517 * .gdbinit (xgetint): Fix recently-introduced paren typo.
2518 Assume USE_2_TAGS_FOR_INTS.
2519 (xreload): Adjust $tagmask width to match recent lisp.h change.
2521 Simplify lisp.h in minor ways that should not affect code.
2522 * lisp.h (USE_2_TAGS_FOR_INTS): Remove, as it was always defined.
2523 (LISP_INT_TAG, case_Lisp_Int, LISP_STRING_TAG, LISP_INT_TAG_P)
2524 (LISP_INT1_TAG, enum Lisp_Type, XINT, XUINT, make_number):
2525 Simplify under the assumption that USE_2_TAGS_FOR_INTS is defined.
2526 (INTTYPEBITS): New macro, for clarity.
2527 (INTMASK, MOST_POSITIVE_FIXNUM): Use it.
2528 (LISP_INT1_TAG, LISP_STRING_TAG, LISP_INT_TAG_P):

2544 * lisp.h (Lisp_Object) [CHECK_LISP_OBJECT_TYPE]: Define as struct
2545 instead of union.
2546 (XLI, XIL): Define.
2547 (XHASH, XTYPE, XINT, XUINT, make_number, XSET, XPNTR, XUNTAG):
2548 Use them.
2549 * emacs.c (gdb_use_struct): Rename from gdb_use_union.

2572 2012-06-13 Paul Eggert <eggert@cs.ucla.edu>
2574 USE_LISP_UNION_TYPE + USE_LSB_TAG cleanup (Bug#11604)
2575 * alloc.c (make_number) [!defined make_number]:

2584 All uses changed.
2585 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
2586 code works fine either way, and efficiency is not a concern here,
2587 as the union type is for debugging, not for production.
2588 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
2589 Use an inline function on all platforms when using the union type,
2590 since this is simpler and 'static inline' can be used portably
2591 within Emacs now.
2592 (LISP_INITIALLY_ZERO): New macro.
2593 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.

2622 * s/irix6-5.h, s/ms-w32.h, s/msdos.h, s/template.h:
2623 * s/usg5-4-common.h: Move SYSTEM_TYPE to configure.
2625 2012-06-11 Stefan Monnier <monnier@iro.umontreal.ca>
2627 * alloc.c (make_byte_code): New function.
2628 (Fmake_byte_code): Use it. Don't purify here.

2633 * image.c (imagemagick_load_image): Implement transparency.
2635 2012-06-10 Andreas Schwab <schwab@linux-m68k.org>
2637 * regex.c (at_begline_loc_p): Also recognize `(?N:' and correctly

2663 dbus_type_is_basic if available.
2664 (xd_extract_signed, xd_extract_unsigned): Rename from
2665 extract_signed and extract_unsigned, respectively. Adapt callers.
2667 2012-06-09 Chong Yidong <cyd@gnu.org>

2672 case (Bug#9752).
2674 2012-06-08 Paul Eggert <eggert@cs.ucla.edu>
2676 * xdisp.c (vmessage): Treat frame message as multibyte.
2677 Without this change, (let ((§ 1)) (make-variable-buffer-local '§))
2678 would generate the diagnostic "Making \302\247 buffer-local while
2679 let-bound!".
2681 2012-06-08 Eli Zaretskii <eliz@gnu.org>
2683 * dispnew.c (showing_window_margins_p): Undo last change, which
2684 was done due to an inadvertent commit.

2697 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
2699 2012-06-08 Eli Zaretskii <eliz@gnu.org>
2701 * alloc.c (allocate_vectorlike): Fix last change.
2703 2012-06-08 Dmitry Antipov <dmantipov@yandex.ru>
2705 Block-based vector allocation of small vectors.
2706 * lisp.h (struct vectorlike_header): New field `nbytes',
2707 adjust comment accordingly.
2708 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'

2723 0 items. Allocate new vector from block if vector size is less than
2724 or equal to VBLOCK_BYTES_MAX.
2725 (Fgarbage_collect): Move all vector sweeping code to sweep_vectors.
2726 (init_alloc_once): Add call to init_vectors.
2728 2012-06-08 Stefan Monnier <monnier@iro.umontreal.ca>
2730 * eval.c (Fmacroexpand): Stop if the macro returns the same form.
2732 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
2734 * doprnt.c (doprnt): Truncate multibyte char correctly.
2735 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
2736 would mishandle a string argument "Xc" if X was a multibyte
2737 character of length 2: it would truncate after X's first byte
2738 rather than including all of X.
2740 2012-06-06 Chong Yidong <cyd@gnu.org>

2748 2012-06-03 Glenn Morris <rgm@gnu.org>
2750 * xdisp.c (tool-bar-style): Doc fix.
2752 2012-06-03 Ulrich Müller <ulm@gentoo.org>
2754 * Makefile.in (PAXCTL): Define.
2755 (temacs$(EXEEXT)): Disable memory randomization for the temacs
2756 binary via PaX flags if the paxctl utility is available.
2757 (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
2758 Restore PaX flags to their default. (Bug#11398)

2767 * xdisp.c (calc_pixel_width_or_height): Use Fbuffer_local_value.
2768 (note_mode_line_or_margin_highlight): If there is no help echo,
2769 use mode-line-default-help-echo. Handle the case where the mouse
2770 position is past the end of the mode line string.
2772 * buffer.c (buffer_local_value_1): New function, split from
2773 Fbuffer_local_value; can return Qunbound.
2774 (Fbuffer_local_value): Use it.
2775 (Vmode_line_format): Docstring tweaks.
2777 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>

2785 and DEFVAR it. Update all users.
2787 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>
2789 * minibuf.c (Fassoc_string): Remove duplicate declaration.
2791 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
2792 Convert pctcpu and pctmem to Lisp float properly.
2793 Let the compiler fold better, as 100.0/0x8000 is exact.
2795 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
2797 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
2798 cons_block.
2800 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
2802 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
2804 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
2806 For a 'struct window', replace some Lisp_Object fields to
2807 bitfields where appropriate, remove unused fields.
2808 * window.h (struct window): Remove unused 'last_mark_x' and
2809 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
2810 change it's type from Lisp_Object to bitfield.
2811 Change type of 'force_start', 'optional_new_start',
2812 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
2813 fields from Lisp_Object to bitfield. Adjust users accordingly.
2815 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
2817 Pacify gcc -Wdouble-precision when using Xaw.
2818 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
2819 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
2820 Use 'float' consistently, rather than 'float' in most places
2821 and 'double' in a couple of places.
2823 2012-05-31 Eli Zaretskii <eliz@gnu.org>
2825 * xdisp.c (handle_stop): Detect whether we have overlay strings
2826 loaded by testing it->current.overlay_string_index to be
2827 non-negative, instead of checking whether n_overlay_strings is
2828 positive. (Bug#11587)
2830 2012-05-31 Chong Yidong <cyd@gnu.org>
2832 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
2834 * doc.c (Fsubstitute_command_keys): Doc fix.
2836 2012-05-31 Eli Zaretskii <eliz@gnu.org>
2838 * search.c (search_buffer): Remove calls to
2839 r_alloc_inhibit_buffer_relocation, as it is now called by
2840 maybe_unify_char, which was the cause of relocation of buffer text
2841 in bug#11519.
2843 2012-05-31 Eli Zaretskii <eliz@gnu.org>
2845 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
2846 for the duration of call to load_charset, to avoid problems with
2847 callers of maybe_unify_char that access buffer text through C
2848 pointers.
2850 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
2851 decrement the inhibition flag, instead of just setting or
2852 resetting it.
2854 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
2856 Remove obsolete '#define static' cruft.
2857 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
2858 This #undef was "temporary" in 2000; it is no longer needed
2859 now that '#define static' has gone away.
2860 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
2861 (gray_bitmap_bits): Remove; no longer needed.
2862 All uses replaced with definiens.
2863 * xterm.c: Include "bitmaps/gray.xbm".
2865 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
2867 Clean up __executable_start, monstartup when --enable-profiling.
2868 The following changes affect the code only when profiling.
2869 * dispnew.c (__executable_start): Rename from safe_bcopy.
2870 Define only on platforms that need it.
2871 * emacs.c: Include <sys/gmon.h> when profiling.
2872 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
2873 (__executable_start): Remove decl, since lisp.h does it now.
2874 (safe_bcopy): Remove decl; no longer has that name.
2875 (main): Coalesce #if into single bit of code, for simplicity.
2876 Cast pointers to uintptr_t, since standard libraries want integers
2877 and not pointers.
2878 * lisp.h (__executable_start): New decl.
2880 2012-05-31 Glenn Morris <rgm@gnu.org>
2882 * image.c (Fimagemagick_types): Doc fix.
2884 2012-05-30 Jim Meyering <meyering@redhat.com>
2886 * callproc.c (Fcall_process_region): Include directory component
2887 in mkstemp error message (Bug#11586).
2889 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>

2898 * data.c (Fdefalias): Purify definition, except for keymaps.
2899 (Qdefun): Move from eval.c.
2900 * lisp.h (Qdefun): Remove.
2901 * lread.c (read1): Tiny simplification.
2903 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
2905 Do not create empty overlays with the evaporate property (Bug#9642).
2906 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
2907 Bug#9642, but explicitly check that the buffer the overlay would
2908 be moved to is live and rearrange lines to make sure that errors
2909 will not put the overlay in an inconsistent state.
2910 (Fdelete_overlay): Cosmetics.
2912 2012-05-28 Eli Zaretskii <eliz@gnu.org>
2914 * w32term.c (my_bring_window_to_top): New function.
2915 (x_raise_frame): Use handle returned by DeferWindowPos, which
2916 could be different from the original one.
2917 Call my_bring_window_to_top instead of my_set_foreground_window.
2918 (Bug#11513)
2920 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
2921 by calling BringWindowToTop.
2923 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
2924 (WM_EMACS_END): Increase by one.
2926 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
2928 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
2929 This avoids undefined behavior that might cause the eassert
2930 to not catch an out-of-range value.
2932 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
2934 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
2935 Update dependencies.
2937 2012-05-27 Eli Zaretskii <eliz@gnu.org>
2939 * bidi.c (bidi_mirror_char): Fix last change.
2941 2012-05-27 Andreas Schwab <schwab@linux-m68k.org>
2943 * unexmacosx.c (copy_data_segment): Truncate after 16 characters
2944 when referring to sectname field in printf format.
2946 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
2948 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
2949 Only r_alloc_inhibit_buffer_relocation needed to be added;
2950 the others were already declared.
2952 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
2953 before checking whether it's out of range. Put the check inside
2954 eassert. See
2955 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
2957 2012-05-27 Ken Brown <kbrown@cornell.edu>
2959 * callproc.c (Fcall_process): Restore a line that was accidentally
2960 commented out in the 2011-02-13 change (bug#11547).
2962 2012-05-27 Eli Zaretskii <eliz@gnu.org>
2964 * lisp.h [REL_ALLOC]: Add prototypes for external functions
2965 defined on ralloc.c.
2967 * buffer.c [REL_ALLOC]: Remove prototypes of
2968 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
2969 they are now on lisp.h.
2971 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
2973 * search.c (search_buffer): Use it to inhibit relocation of buffer
2974 text while re_search_2 is doing its job, because re_search_2 is
2975 passed C pointers to buffer text. (Bug#11519)
2977 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
2978 Update value to 24.
2980 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
2981 state after an additional call to move_it_in_display_line_to, keep
2982 the values of it->max_ascent and it->max_descent found for the
2983 entire line.
2984 (pos_visible_p): Revert the comparison against bottom_y to what it
2985 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
2986 (Bug#11464)
2988 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
2990 Fix coding-related core dumps with gcc -ftrapv.
2991 The code was computing A - B, where A and B are pointers, and B is
2992 random garbage. This can lead to core dumps on platforms that
2993 have special pointer registers, and it also leads to core dumps on
2994 x86-64 when compiled with gcc -ftrapv. The fix is to compute
2995 A - B only when B is initialized properly.
2996 * coding.c (coding_set_source, coding_set_destination): Return void.
2997 (coding_change_source, coding_change_destinations): New functions,
2998 with the old behaviors of coding_set_source and coding_set_destination.
2999 All callers that need an offset changed to use these new functions.
3001 2012-05-26 Glenn Morris <rgm@gnu.org>
3003 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
3005 2012-05-26 Eli Zaretskii <eliz@gnu.org>
3007 Extend mouse support on W32 text-mode console.
3008 * xdisp.c (draw_row_with_mouse_face):
3009 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
3011 * w32console.c: Include window.h.
3012 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
3013 New functions.
3014 (initialize_w32_display): Initialize mouse-highlight data.
3016 * w32inevt.c: Include termchar.h and window.h.
3017 (do_mouse_event): Support mouse-autoselect-window. When the mouse
3018 moves, call note_mouse_highlight. If help_echo changed, call
3019 gen_help_event to produce help-echo message in the echo area.
3020 Call clear_mouse_face if mouse_face_hidden is set in the mouse
3021 highlight info.
3023 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3025 * lread.c (read1): Simplify slightly to avoid an overflow warning
3026 with GCC 4.7.0 on x86-64.
3028 2012-05-26 Eli Zaretskii <eliz@gnu.org>
3030 * bidi.c (bidi_mirror_char): Revert last change: an int is
3031 definitely wide enough here.
3033 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
3035 Fix integer width and related bugs (Bug#9874).
3036 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
3037 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
3038 (string_bytes, check_sblock, allocate_string_data):
3039 (compact_small_strings, Fmake_bool_vector, make_string)
3040 (make_unibyte_string, make_multibyte_string)
3041 (make_string_from_bytes, make_specified_string)
3042 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
3043 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
3044 (mark_vectorlike):
3045 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3046 (allocate_pseudovector):
3047 Use int, not EMACS_INT, where int is wide enough.
3048 (inhibit_garbage_collection, Fgarbage_collect):
3049 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3050 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
3051 int might not be wide enough.
3052 (bidi_cache_search, bidi_cache_find, bidi_init_it)
3053 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
3054 (bidi_at_paragraph_end, bidi_find_paragraph_start)
3055 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
3056 (bidi_level_of_next_char, bidi_move_to_visually_next):
3057 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3058 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
3059 (Fkill_buffer, Fset_buffer_major_mode)
3060 (advance_to_char_boundary, Fbuffer_swap_text)
3061 (Fset_buffer_multibyte, overlays_at, overlays_in)
3062 (overlay_touches_p, struct sortvec, record_overlay_string)
3063 (overlay_strings, recenter_overlay_lists)
3064 (adjust_overlays_for_insert, adjust_overlays_for_delete)
3065 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
3066 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
3067 (Foverlay_recenter, last_overlay_modification_hooks_used)
3068 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
3069 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3070 (validate_region): Omit unnecessary test for b <= e,
3071 since that's guaranteed by the previous test.
3072 (adjust_overlays_for_delete): Avoid pos + length overflow.
3073 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
3074 (report_overlay_modification):
3075 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3076 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
3077 Omit pointer cast, which isn't needed anyway, and doesn't work
3078 after the EMACS_INT -> ptrdiff_t change.
3079 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
3080 * buffer.h: Adjust decls to match defn changes elsewhere.
3081 (struct buffer_text, struct buffer):
3082 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3083 Use EMACS_INT, not int, where int might not be wide enough.
3084 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
3085 not int, to avoid needless 32-bit limit on 64-bit hosts.
3086 (exec_byte_code): Use tighter memory-full test, one that checks
3087 for alloca overflow. Don't compute the address of the object just
3088 before an array, as that's not portable. Use EMACS_INT, not
3089 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
3090 * callint.c (Fcall_interactively):
3091 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3092 * callproc.c (call_process_kill, Fcall_process):
3093 Don't assume pid_t fits into an Emacs fixnum.
3094 (call_process_cleanup, Fcall_process, child_setup):
3095 Don't assume pid_t fits into int.
3096 (call_process_cleanup, Fcall_process, delete_temp_file)
3097 (Fcall_process_region):
3098 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3099 (Fcall_process): Simplify handling of volatile integers.
3100 Use int, not EMACS_INT, where int will do.
3101 * casefiddle.c (casify_object, casify_region, operate_on_word)
3102 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
3103 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3104 (casify_object): Avoid integer overflow when overallocating buffer.
3105 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
3106 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
3107 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
3108 * category.h (CATEGORYP): Don't assume arg is nonnegative.
3109 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
3110 integers are now checked earlier. All uses replaced with XINT.
3111 (ccl_driver):
3112 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3113 For CCL_MapSingle, check that content and value are in int range.
3114 (ccl_driver, Fregister_code_conversion_map):
3115 Check that Vcode_version_map_vector is a vector.
3116 (resolve_symbol_ccl_program): Check that vector header is in range.
3117 Always copy the vector, so that we can check its contents reliably
3118 now rather than having to recheck each instruction as it's being
3119 executed. Check that vector words fit in 'int'.
3120 (ccl_get_compiled_code, Fregister_ccl_program)
3121 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
3122 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
3123 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
3124 contents are in range.
3125 (Fccl_execute_on_string): Check that status is in range.
3126 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
3127 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
3128 Accept and return EMACS_INT, not int, because callers can pass values
3129 out of 'int' range.
3130 (c_string_width, strwidth, lisp_string_width, chars_in_text)
3131 (multibyte_chars_in_text, parse_str_as_multibyte)
3132 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)
3133 (str_as_unibyte, str_to_unibyte, string_count_byte8)
3134 (string_escape_byte8, Fget_byte):
3135 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3136 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
3137 avoid mishandling large integers.
3138 * character.h: Adjust decls to match defn changes elsewhere.
3139 * charset.c (load_charset_map_from_file, find_charsets_in_text)
3140 (Ffind_charset_region):
3141 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3142 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
3143 (load_charset_map_from_vector, Fdefine_charset_internal):
3144 Don't assume fixnum fits in int.
3145 (load_charset_map_from_vector, Fmap_charset_chars):
3146 Remove now-unnecessary CHECK_NATNUMs.
3147 (Fdefine_charset_internal): Check ranges here, more carefully.
3148 Don't rely on undefined behavior with signed left shift overflow.
3149 Don't assume unsigned int fits into fixnum, or that fixnum fits
3150 into unsigned int. Don't require max_code to be a valid fixnum;
3151 that's not true for gb10830 4-byte on a 32-bit host. Allow
3152 invalid_code to be a cons, for the same reason. Require code_offset
3153 to be a character. Avoid int overflow if max_char is close
3154 to INT_MAX.
3155 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
3156 this is intended anyway and avoids some undefined behavior.
3157 (load_charset_map): Pass unsigned, not int, as 2nd arg of
3158 INDEX_TO_CODE_POINT, as that's what it expects.
3159 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
3160 * charset.h (DECODE_CHAR): Return int, not unsigned;
3161 this is what was intended anyway, and it avoids undefined behavior.
3162 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
3163 integer-overflow issues.
3164 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
3165 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
3166 where the argument is EMACS_INT, and this behavior is not intended.
3167 * chartab.c (Fmake_char_table, Fset_char_table_range)
3168 (uniprop_get_decoder, uniprop_get_encoder):

3865 * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:
3866 * m/template.h: Remove.
3867 * Makefile.in (M_FILE): Remove. All uses removed.
3868 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS):
3869 * lisp.h (USE_LSB_TAG):
3870 * mem-limits.h (EXCEEDS_LISP_PTR):
3871 Use VAL_MAX, not VALBITS, in #if.
3872 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
3873 (EMACS_UINT): Define unconditionally now.
3874 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
3875 (BITS_PER_EMACS_INT): New constants, replacing
3876 what used to be in config.h, but not useful in #if.
3877 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
3878 define them any more.
3879 (VAL_MAX): New macro.
3880 (VALMASK): Use it.
3881 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
3882 BITS_PER_EMACS_INT, in #if.
3883 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
3884 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
3885 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
3886 * s/ms-w32.h (DATA_START):
3887 Move here from removed file m/intel386.h.
3888 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
3889 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
3891 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
3893 Assume C89 or later.
3894 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
3895 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
3896 (xrealloc):
3897 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.
3898 * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):
3899 * textprop.c, tparam.c (NULL): Remove.
3900 * ralloc.c, vm-limit.c (POINTER): Assume void * works.
3901 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
3902 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
3903 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
3904 * xterm.c (input_signal_count): Assume volatile works.
3906 2012-05-21 Ken Brown <kbrown@cornell.edu>
3908 * xgselect.c (xg_select): Fix first argument in call to 'select'
3909 (bug#11508).
3911 2012-05-20 Ken Brown <kbrown@cornell.edu>
3913 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
3914 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
3916 2012-05-19 Ken Brown <kbrown@cornell.edu>
3918 * xfns.c (x_in_use): Remove `static' qualifier.
3919 * xterm.h (x_in_use): Declare.
3920 * xgselect.c: Include xterm.h.
3921 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
3922 and `display_arg' (bug#9754).
3924 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
3926 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
3928 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
3929 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
3931 2012-05-18 Eli Zaretskii <eliz@gnu.org>
3933 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
3935 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
3936 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
3938 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
3939 reference to image_cache->refcount.
3940 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
3942 2012-05-17 Juri Linkov <juri@jurta.org>
3944 * search.c (Fword_search_regexp, Fword_search_backward)
3945 (Fword_search_forward, Fword_search_backward_lax)
3946 (Fword_search_forward_lax): Move functions to isearch.el
3947 (bug#10145, bug#11381).
3949 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
3951 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
3953 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
3955 * lread.c (init_obarray): Declare Qt and Qnil as special.
3957 2012-05-14 Glenn Morris <rgm@gnu.org>
3959 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
3960 Put "libexec" before "bin", for the sake of init_callproc_1.
3962 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
3964 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
3966 * unexaix.c: Port to more-recent AIX compilers.
3967 (report_error, report_error_1, make_hdr, copy_sym)
3968 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
3969 Make arguments const char *, not char *, to avoid violations of C
3970 standard and to fix some AIX warnings reported by Gilles Pion.
3972 2012-05-14 Eli Zaretskii <eliz@gnu.org>
3974 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
3975 already have overlays loaded.
3976 (handle_single_display_spec): Before returning without displaying
3977 fringe bitmap, synchronize the bidi iterator with the main display
3978 iterator, by calling iterate_out_of_display_property.
3979 (iterate_out_of_display_property): Detect buffer iteration by
3980 testing that it->string is a Lisp string.
3981 (get_next_display_element): When the current object is exhausted,
3982 and there's something on it->stack, call set_iterator_to_next to
3983 proceed with what's on the stack, instead of returning zero.
3984 (set_iterator_to_next): If called at the end of a Lisp string,
3985 proceed to consider_string_end without incrementing string
3986 position. Don't increment display vector index past the end of
3987 the display vector. (Bug#11417)
3988 (pos_visible_p): Don't report a position visible when move_it_to
3989 stopped at the last line of window, which happens to be scanned
3990 backwards by the bidi iteration. (Bug#11464)
3992 2012-05-14 Eli Zaretskii <eliz@gnu.org>
3994 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
3995 and right-margin display specs even if the spec is invalid or we
3996 are on a TTY, and thus unable to display on the fringes.
3997 That's because the text with the property will not be displayed anyway,
3998 so we need to signal to the caller that this is a "replacing"
3999 display spec. This fixes display when the spec is invalid or we
4000 are on a TTY.
4002 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
4004 * unexaix.c (make_hdr): Fix typo in prototype.
4005 This bug broke the build on AIX. Problem reported by Gilles Pion.
4007 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
4009 * keyboard.c (kbd_buffer_get_event): Read special events also in
4010 batch mode. (Bug#11415)
4012 2012-05-12 Glenn Morris <rgm@gnu.org>
4014 * ns.mk: Update for ns_appbindir no longer having trailing "/".
4016 2012-05-12 Eli Zaretskii <eliz@gnu.org>
4018 * lisp.mk (lisp): Add newcomment.elc.
4020 2012-05-12 Glenn Morris <rgm@gnu.org>
4022 * Makefile.in (MKDIR_P): New, set by configure.
4023 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
4025 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
4027 Remove unused function hourglass_started.
4028 * dispextern.h (hourglass_started):
4029 * w32fns.c (hourglass_started):
4030 * xdisp.c (hourglass_started): Remove.
4032 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
4034 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
4035 Update dependencies.
4037 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
4039 * xgselect.c (xg_select): Put maxfds+1 into a var.
4040 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
4042 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
4044 2012-05-10 Dave Abrahams <dave@boostpro.com>
4046 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
4047 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
4049 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
4051 * dbusbind.c (xd_registered_buses): New internal Lisp object.
4052 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
4053 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
4054 Initialize xd_registered_buses.
4056 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
4058 Untag more efficiently if USE_LSB_TAG.
4059 This is based on a proposal by YAMAMOTO Mitsuharu in
4060 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
4061 For an admittedly artificial (nth 8000 longlist) benchmark on
4062 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
4063 Emacs's overall text size by 1%.
4064 * lisp.h (XUNTAG): New macro.
4065 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
4066 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
4067 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
4068 * eval.c (Fautoload):
4069 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
4070 * frame.h (XFRAME): Use XUNTAG.
4072 Port recent dbusbind.c changes to 32-bit --with-wide-int.
4073 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
4074 Remove unportable assumptions about print widths of types like
4075 dbus_uint32_t.
4076 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
4077 intptr_t when converting between pointer and integer, to avoid GCC
4078 warnings about wrong width.
4080 2012-05-09 Eli Zaretskii <eliz@gnu.org>
4082 * w32proc.c (new_child): Force Windows to reserve only 64KB of
4083 stack for each reader_thread, instead of defaulting to 8MB
4084 determined by the linker. This avoids failures in creating
4085 subprocesses on Windows 7, see the discussion in this thread:
4086 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
4088 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
4090 Fix up display of the *Minibuf-0* buffer in the mini window.
4091 * keyboard.c (read_char): Don't clear the echo area if there's no
4092 message to clear.
4093 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
4094 contents of *Minibuf-0*) if there's no message displayed in its stead.
4096 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
4098 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
4099 batch mode.
4101 2012-05-06 Chong Yidong <cyd@gnu.org>
4103 * lisp.mk (lisp): Update.
4105 2012-05-05 Jim Meyering <meyering@redhat.com>
4107 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
4109 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
4111 * data.c (PUT_ERROR): New macro.
4112 (syms_of_data): Use it. Add new error type `user-error'.
4113 * undo.c (user_error): New function.
4114 (Fprimitive_undo): Use it.
4115 * print.c (print_error_message): Adjust print style for `user-error'.
4116 * keyboard.c (user_error): New function.
4117 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
4119 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
4121 Do not limit current-time-string to years 1000..9999.
4122 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
4123 (Fcurrent_time_string): Support any year that is supported by the
4124 underlying localtime representation. Don't use asctime, as it
4125 has undefined behavior for years outside the range -999..9999.
4127 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
4129 Fix race conditions involving setenv, gmtime, localtime, asctime.
4130 Without this fix, interrupts could mess up code that uses these
4131 nonreentrant functions, since setting TZ invalidates existing
4132 tm_zone or tzname values, and since most of these functions return
4133 pointers to static storage.
4134 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
4135 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
4136 Grow the critical sections to include not just invoking
4137 localtime/gmtime, but also accessing these functions' results
4138 including their tm_zone values if any, and any related TZ setting.
4139 (format_time_string): Last arg is now struct tm *, not struct tm **,
4140 so that the struct tm is saved in the critical section.
4141 All callers changed. Simplify allocation of initial buffer, partly
4142 motivated by the fact that memory allocation needs to be outside
4143 the critical section.
4145 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
4147 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
4148 with RESET_INTERVAL.
4150 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
4151 Remove duplicated buffer name initialization.
4153 2012-05-02 Jim Meyering <jim@meyering.net>
4155 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
4157 * xfns.c (x_window): Use xstrdup (Bug#11375).
4159 2012-05-02 Eli Zaretskii <eliz@gnu.org>
4161 * xdisp.c (pos_visible_p): If already at a newline from the
4162 display string before the 'while' loop, don't walk back the glyphs
4163 from it3.glyph_row. Solves assertion violation when the display
4164 string begins with a newline (egg.el). (Bug#11367)
4166 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
4168 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
4169 Move to simple.el.
4171 2012-05-01 Glenn Morris <rgm@gnu.org>
4173 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
4174 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
4175 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
4176 All were removed before 23.1.
4178 * dispnew.c: Remove HAVE_LIBNCURSES test;
4179 it is always true on relevant platforms.
4181 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
4182 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
4184 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
4186 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
4188 * .gdbinit (xpr): Remove checks for no longer existing misc types.
4189 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
4190 Remove.
4192 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
4194 Do not avoid creating empty evaporating overlays (Bug#9642).
4195 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
4196 That is, do not delete an evaporating overlay if it becomes
4197 empty after its bounds are adjusted to fit within its buffer.
4198 This fix caused other problems, and I'm reverting it until we get
4199 to the bottom of them.
4201 2012-04-27 Chong Yidong <cyd@gnu.org>
4203 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
4205 2012-04-27 Eli Zaretskii <eliz@gnu.org>
4207 * xdisp.c (pos_visible_p): If the window start position is beyond
4208 ZV, start the display from buffer beginning. Prevents assertion
4209 violation in init_iterator when the minibuffer window is scrolled
4210 via the scroll bar.
4212 * window.c (window_scroll_pixel_based): Likewise.
4214 2012-04-27 Chong Yidong <cyd@gnu.org>
4216 * keymap.c (where_is_internal): Doc fix (Bug#10872).
4218 2012-04-27 Glenn Morris <rgm@gnu.org>
4220 * fileio.c (Fcopy_file, Fset_file_selinux_context):
4221 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
4223 2012-04-27 Eli Zaretskii <eliz@gnu.org>
4225 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
4226 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
4228 2012-04-26 Eli Zaretskii <eliz@gnu.org>
4230 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
4231 display element, check also the underlying string or buffer
4232 character. (Bug#11341)
4234 * w32menu.c: Include w32heap.h.
4235 (add_menu_item): If the call to AppendMenuW (via
4236 unicode_append_menu) fails, disable Unicode menus only if we are
4237 running on Windows 9X/Me.
4239 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
4241 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
4242 (xgetint): Add missing shift for LSB tags.
4244 2012-04-24 Martin Rudalics <rudalics@gmx.at>
4246 * keyboard.c (read_char): Don't wipe echo area for select window
4247 events: These might get delayed via `mouse-autoselect-window'
4248 (Bug#11304).
4250 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
4252 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
4253 manipulation of :loaded-from data.
4255 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
4257 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
4258 now a cons (bug#11311).
4260 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
4262 Do not create empty overlays with the evaporate property (Bug#9642).
4263 * buffer.c (Fmove_overlay): Delete an evaporating overlay
4264 if it becomes empty after its bounds are adjusted to fit within
4265 its buffer. Without this fix, in a nonempty buffer (let ((o
4266 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
4267 yields an empty overlay that has the evaporate property, which is
4268 not supposed to happen.
4270 Fix minor GTK3 problems found by static checking.
4271 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
4272 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
4273 (struct _EmacsFixedClass, emacs_fixed_get_type):
4274 Move decls here from emacsgtkfixed.h, since they needn't be public.
4275 (emacs_fixed_get_type): Now static.
4276 (emacs_fixed_class_init): Omit unused local.
4277 (emacs_fixed_child_type): Remove; unused.
4278 * emacsgtkfixed.h (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
4279 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
4280 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
4281 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
4282 (EMACS_FIXED_GET_CLASS): Remove; unused.
4283 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
4285 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
4286 Problem reported by Juanma Barranquero for Windows -Wunused-function.
4288 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
4290 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
4291 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
4292 (__malloc_size_t, __malloc_ptrdiff_t):
4293 Remove. All uses removed, replaced by the definiens if needed,
4294 since we can assume C89 or better now.
4295 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
4296 (protect_malloc_state, align, get_contiguous_space)
4297 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)
4298 (malloc_atfork_handler_child, malloc_enable_thread)
4299 (malloc_initialize_1, __malloc_initialize, morecore_nolock)
4300 (_malloc_internal_nolock, _malloc_internal, malloc, _malloc)
4301 (_free, _realloc, _free_internal_nolock, _free_internal, free, cfree)
4302 (special_realloc, _realloc_internal_nolock, _realloc_internal)
4303 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
4304 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
4305 Define using prototypes, not old style.

4372 since the two debugging options are incompatible.
4373 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
4374 is defined.
4375 (mem_init, mem_insert, mem_insert_fixup):
4376 Define if GC_MARK_STACK || GC_MALLOC_CHECK.
4377 (NEED_MEM_INSERT): Remove; no longer needed.
4379 2012-04-22 Leo Liu <sdl.web@gmail.com>

4411 2012-04-20 Chong Yidong <cyd@gnu.org>
4413 * process.c (wait_reading_process_output): If EIO occurs on a pty,
4414 set the status to "failed" and ensure that sentinel is run.

4469 New extern decls, to avoid calling undeclared functions.
4470 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
4471 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
4472 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
4473 (NEED_MEM_INSERT): New macro.
4474 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.

4489 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
4490 Remove decls. This fixes an "It stinks!".

4494 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
4496 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

4507 2012-04-14 Paul Eggert <eggert@cs.ucla.edu>
4509 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
4510 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
4511 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
4512 * s/netbsd.h, s/sol2-6.h:
4513 Remove definition of GC_MARK_STACK, since the default now works.
4514 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
4515 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
4516 no longer the default.
4517 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
4519 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

4542 2012-04-11 Daniel Colascione <dancol@dancol.org>
4544 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
4545 against is gone. It's better to use vfork now so that when Cygwin
4546 gains a new, working vfork, we use it automatically (bug#10398).
4548 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
4550 * window.c (save_window_save): Obey window-point-insertion-type.

4569 being loaded (bug#10424).
4571 2012-04-09 Glenn Morris <rgm@gnu.org>
4573 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
4574 not just in the obarray, before snarfing them. (Bug#11036)

4592 attempts per process (connection).
4594 2012-04-09 Chong Yidong <cyd@gnu.org>
4596 * eval.c (Fuser_variable_p, user_variable_p_eh)

4601 * minibuf.c (Fread_variable): Callers changed.
4603 2012-04-09 Eli Zaretskii <eliz@gnu.org>
4605 * xdisp.c (set_cursor_from_row): If the display string appears in
4606 the buffer at position that is closer to point than the position
4607 after the display string, display the cursor on the first glyph of
4608 the display string. Fixes cursor display when a 'display' text
4609 property immediately follows invisible text. (Bug#11094)
4611 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
4613 composite.c: use 'double' consistently
4614 * composite.c (get_composition_id): Use 'double' consistently
4615 instead of converting 'float' to 'double' and vice versa; this is
4616 easier to understand and avoids a GCC warning.
4618 2012-04-09 Glenn Morris <rgm@gnu.org>
4620 * Makefile.in: Generate leim-list with bootstrap-emacs, in

4663 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
4664 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
4665 [!WINDOWSNT]: New macros.
4666 (init_libxml2_functions, libxml2_loaded_p): New functions.
4667 (parse_region): Call fn_xmlCheckVersion instead of using the macro
4668 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
4669 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
4670 Calls xmlCleanupParser only if libxml2 was loaded (or statically
4671 linked in).
4672 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
4673 Call init_libxml2_functions before calling libxml2 functions.
4674 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
4676 * emacs.c: Don't include libxml/parser.h.
4677 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
4678 xmlCleanupParser directly.
4680 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
4682 2012-04-07 Eli Zaretskii <eliz@gnu.org>
4684 * indent.c (Fvertical_motion): If there is a display string at
4685 point, use it.vpos to compute how many lines to backtrack after
4686 move_it_to point. (Bug#11133)
4688 2012-04-06 Eli Zaretskii <eliz@gnu.org>
4690 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
4691 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
4692 about subtle differences between FETCH_CHAR* and STRING_CHAR*
4693 macros related to unification of CJK characters. For the details,
4694 see the discussion following the message here:
4695 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
4697 2012-04-04 Chong Yidong <cyd@gnu.org>

4711 2012-03-31 Eli Zaretskii <eliz@gnu.org>
4713 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
4714 position we get to after a call to move_it_to fails the
4715 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
4716 only if we wind up in a string from display property. (Bug#11063)
4718 * window.c (Fdelete_other_windows_internal): Invalidate the row
4719 and column information about mouse highlight, so that redisplay
4720 restores it after reallocating the glyph matrices. (Bug#7464)
4722 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
4723 string comes from a `display' text property, use the buffer
4724 position of that property as if we actually saw that position in
4725 the row's glyphs.
4726 (move_it_by_lines): Remove the assertion that
4727 "it->current_x == 0 && it->hpos == 0" which can be legitimately
4728 violated when there's a before-string at the beginning of a line.
4729 (Bug#11063)
4731 2012-03-30 Eli Zaretskii <eliz@gnu.org>
4733 * xdisp.c (append_space_for_newline): If the default face was
4734 remapped, use the remapped face for the appended newline.
4735 (extend_face_to_end_of_line): Use the remapped default face for
4736 extending the face to the end of the line.
4737 (display_line): Call extend_face_to_end_of_line when the default
4738 face was remapped. (Bug#11068)
4740 2012-03-29 Eli Zaretskii <eliz@gnu.org>

4760 * keyboard.c (Vselection_inhibit_update_commands): New variable.
4761 (command_loop_1): Use it; inhibit selection update for
4762 handle-select-window too (Bug#8996).
4764 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
4766 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
4768 2012-03-25 Kenichi Handa <handa@m17n.org>
4770 * dispextern.h (struct glyph): Change the bit length of
4771 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
4773 2012-03-24 Eli Zaretskii <eliz@gnu.org>
4775 * s/ms-w32.h (tzname): Include time.h before redirecting to
4776 _tzname. Fixes the MSVC build. (Bug#9960)
4778 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
4780 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
4781 characters.
4783 * xterm.c (XTread_socket): Only modify handling_signal if
4784 !SYNC_INPUT. (Bug#11080)
4786 2012-03-23 Eli Zaretskii <eliz@gnu.org>
4788 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
4789 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
4790 when fetching a multibyte character consumes more bytes than
4791 CHAR_BYTES returns, due to unification of CJK characters in
4792 string_char. (Bug#11073)
4794 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
4796 * process.c (wait_reading_process_output): Handle pty disconnect
4797 by refraining from sending oneself a SIGCHLD (bug#10933).
4799 2012-03-22 Chong Yidong <cyd@gnu.org>

4803 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
4804 Mark string as coming from a prefix property.
4805 (handle_face_prop): Use default face for prefix strings (Bug#4281).
4806 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
4808 2012-03-21 Chong Yidong <cyd@gnu.org>
4810 * xfaces.c (Vface_remapping_alist): Doc fix.
4812 2012-03-20 Eli Zaretskii <eliz@gnu.org>
4814 * w32proc.c (Fw32_set_console_codepage)
4815 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
4816 Doc fixes.
4818 2012-03-20 Chong Yidong <cyd@gnu.org>
4820 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
4821 to reflect default non-nil value of redisplay-dont-pause.
4823 2012-03-19 Kenichi Handa <handa@m17n.org>
4825 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
4826 it fit in a valid range (Bug#11003).
4828 2012-03-18 Eli Zaretskii <eliz@gnu.org>
4830 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
4831 that is not from display property, accept the row as a "cursor
4832 row" if one of the string's character has a non-nil `cursor'
4833 property. Fixes cursor positioning when there are newlines in
4834 overlay strings, e.g. in icomplete.el. (Bug#11035)
4836 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
4838 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
4840 2012-03-12 Chong Yidong <cyd@gnu.org>
4842 * eval.c (inhibit_lisp_code): Rename from
4843 inhibit_window_configuration_change_hook; move from window.c.
4845 * xfns.c (unwind_create_frame_1, Fx_create_frame):
4846 * window.c (run_window_configuration_change_hook)
4847 (syms_of_window): Callers changed.
4849 2012-03-11 Chong Yidong <cyd@gnu.org>
4851 * keymap.c (Fkey_description): Doc fix (Bug#9700).

4858 is visible (Bug#10955).
4860 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
4862 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
4864 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
4866 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
4867 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
4868 zero (Bug#10954).
4870 2012-03-03 Glenn Morris <rgm@gnu.org>
4872 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
4874 2012-03-02 Eli Zaretskii <eliz@gnu.org>
4876 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
4877 position past the first glyph_row that ends at ZV. (Bug#10902)
4878 (redisplay_window, next_element_from_string): Fix typos in
4879 comments.
4880 (redisplay_window): Pass to move_it_vertically the margin in
4881 pixels, not in screen lines.
4883 2012-03-02 Glenn Morris <rgm@gnu.org>
4885 * buffer.c (buffer-list-update-hook): Doc fix.
4887 2012-02-29 Eli Zaretskii <eliz@gnu.org>
4889 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
4890 push_it before setting up the iterator for the first overlay
4891 string, even if we have an empty string loaded.
4892 (next_overlay_string): If there's an empty string on the iterator
4893 stack, pop the stack. (Bug#10903)
4895 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
4897 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
4898 Suggested by Stefan Monnier in
4899 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
4900 * alloc.c (widen_to_Lisp_Object): New static function.
4901 (mark_memory): Also mark Lisp_Objects by fetching pointer words
4902 and widening them to Lisp_Objects. This would work even if
4903 USE_LSB_TAG is defined and wide integers are used, which might
4904 happen in a future version of Emacs.
4906 2012-02-25 Chong Yidong <cyd@gnu.org>
4908 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
4909 Doc fix.
4911 * xselect.c (Fx_selection_exists_p): Doc fix.
4912 (x_clipboard_manager_save_all): Print an informative message
4913 before saving to clipboard manager.
4915 2012-02-24 Chong Yidong <cyd@gnu.org>
4917 * keyboard.c (process_special_events): Handle all X selection
4918 requests in kbd_buffer, not just the next one (Bug#8869).
4920 2012-02-23 Chong Yidong <cyd@gnu.org>
4922 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
4923 call when setting menu-bar-lines and tool-bar-lines parameters.
4924 (unwind_create_frame_1): New helper function.
4926 * window.c (inhibit_window_configuration_change_hook): New var.
4927 (run_window_configuration_change_hook): Obey it.
4928 (syms_of_window): Initialize it.
4930 2012-02-22 Chong Yidong <cyd@gnu.org>
4932 * xterm.c (x_draw_image_relief): Add missing type check for
4933 Vtool_bar_button_margin (Bug#10743).
4935 2012-02-21 Chong Yidong <cyd@gnu.org>
4937 * fileio.c (Vfile_name_handler_alist): Doc fix.
4939 * buffer.c (Fget_file_buffer): Protect against invalid file
4940 handler return value.
4942 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
4944 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
4945 when computing $valmask.
4947 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
4948 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
4949 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
4950 It's useless in that case, and it can cause problems on hosts
4951 that allocate halves of EMACS_INT values separately.
4952 Reported by Dan Horák. Diagnosed by Andreas Schwab in
4953 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
4954 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
4955 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
4956 it avoids undefined behavior on hosts where shifting right by more
4957 than the word width has undefined behavior.
4959 2012-02-19 Chong Yidong <cyd@gnu.org>
4961 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
4962 (Funhandled_file_name_directory, Ffile_name_as_directory)
4963 (Fdirectory_file_name, Fexpand_file_name)
4964 (Fsubstitute_in_file_name): Protect against invalid file handler
4965 return values (Bug#10845).
4967 2012-02-18 Eli Zaretskii <eliz@gnu.org>
4969 * .gdbinit (pitx): Fix incorrect references to fields of the

4979 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
4981 2012-02-15 Chong Yidong <cyd@gnu.org>
4983 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
4984 marked as special. Also, starting docstrings with * is obsolete.

4988 * gnutls.c (emacs_gnutls_write): Fix last change.
4990 2012-02-13 Lars Ingebrigtsen <larsi@gnus.org>

4995 2012-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
4997 * keymap.c (Fsingle_key_description): Handle char ranges.
4999 2012-02-12 Chong Yidong <cyd@gnu.org>
5001 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
5002 as that creates a dangerous corner case.
5004 * window.c (Fdelete_window_internal): Invalidate the mouse
5005 highlight (Bug#9904).
5007 2012-02-12 Glenn Morris <rgm@gnu.org>
5009 * xselect.c (Fx_own_selection_internal)
5010 (Fx_get_selection_internal, Fx_disown_selection_internal)
5011 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
5012 * nsselect.m (Fx_own_selection_internal)
5013 (Fx_disown_selection_internal, Fx_selection_exists_p)
5014 (Fx_selection_owner_p, Fx_get_selection_internal):
5015 Sync docs and argument specs with the xselect.c versions.
5017 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
5019 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
5021 2012-02-11 Eli Zaretskii <eliz@gnu.org>
5023 * w32select.c (Fx_selection_exists_p): Sync doc string and
5024 argument list with xselect.c. (Bug#10783)

5037 2012-02-07 Chong Yidong <cyd@gnu.org>
5039 * buffer.c (Fbuffer_local_variables)
5040 (buffer_lisp_local_variables): Handle unbound vars correctly;
5041 don't let Qunbound leak into Lisp.
5043 2012-02-07 Glenn Morris <rgm@gnu.org>
5045 * image.c (Fimagemagick_types): Doc fix.
5047 * image.c (imagemagick-render-type): Change it from a lisp object
5048 to an integer. Move the doc here from the lisp manual.

5053 * doc.c (store_function_docstring): Avoid applying docstring of
5054 alias to base function (Bug#2603).
5056 2012-02-04 Andreas Schwab <schwab@linux-m68k.org>
5058 * .gdbinit (pp1, pv1): Remove redundant defines.
5059 (pr): Use pp.
5061 2012-02-04 Chong Yidong <cyd@gnu.org>
5063 * nsterm.m: Declare a global (Bug#10694).
5065 2012-02-04 Eli Zaretskii <eliz@gnu.org>
5067 * w32.c (get_emacs_configuration_options):
5068 Include --enable-checking, if specified, in the return value.
5070 2012-02-04 Martin Rudalics <rudalics@gmx.at>
5072 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
5073 after rounding frame sizes. (Bug#9723)
5075 2012-02-04 Eli Zaretskii <eliz@gnu.org>

5078 before BEGV. (Bug#10696)
5080 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
5082 Handle overflow when computing char display width (Bug#9496).
5083 * character.c (char_width): Return EMACS_INT, not int.
5084 (char_width, c_string_width): Check for overflow when
5085 computing the width; this is possible now that individual
5086 characters can have unbounded width. Problem introduced
5087 by merge from Emacs 23 on 2012-01-19.
5089 2012-02-02 Michael Albinus <michael.albinus@gmx.de>
5091 * dbusbind.c (Fdbus_register_method): Mention the return value

5104 2012-02-02 Kenichi Handa <handa@m17n.org>
5106 (x_produce_glyphs): Cancel previous change. If cmp->glyph_len is
5107 0, do not call append_composite_glyph.

5111 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
5112 NULL (Bug#6988).
5113 (x_produce_glyphs): If the component of a composition is a null
5114 string, set it->pixel_width to 1 to avoid zero-width glyph.
5116 2012-02-01 Eli Zaretskii <eliz@gnu.org>
5118 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
5119 first 2 arguments are identical. This makes inserting large
5120 output from a subprocess an order of magnitude faster on
5121 MS-Windows, where all sbrk'ed memory is always contiguous.
5123 2012-01-31 Glenn Morris <rgm@gnu.org>
5125 * nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:

5161 2012-01-21 Chong Yidong <cyd@gnu.org>
5163 * floatfns.c (Fcopysign): Make the second argument non-optional,
5164 since nil is not allowed anyway.
5166 2012-01-21 Andreas Schwab <schwab@linux-m68k.org>

5179 * character.c (char_width): New function.
5180 (Fchar_width, c_string_width, lisp_string_width):
5181 Use char_width (Bug#9496).
5183 2012-01-16 Martin Rudalics <rudalics@gmx.at>
5185 * window.c (Vwindow_persistent_parameters): New variable.
5186 (Fset_window_configuration, save_window_save): Handle persistent
5187 window parameters.
5189 2012-01-14 Eli Zaretskii <eliz@gnu.org>
5191 * w32fns.c (signal_user_input): Don't do a QUIT, to avoid

5204 before a R2L line.
5206 2012-01-11 Glenn Morris <rgm@gnu.org>
5208 * lread.c (init_lread): If no-site-lisp, remove site-lisp dirs
5209 from load-path also when installation-directory is nil. (Bug#10208)
5211 2012-01-10 Glenn Morris <rgm@gnu.org>
5213 * emacs.c (syms_of_emacs) <installation-directory>: Doc fix.
5215 * epaths.in (PATH_LOADSEARCH, PATH_EXEC, PATH_DATA, PATH_DOC):
5216 Update template values to be closer to their typical values these days.
5218 2012-01-09 Eli Zaretskii <eliz@gnu.org>
5220 * xdisp.c (rows_from_pos_range): Accept additional argument
5221 DISP_STRING, and accept any glyph in a row whose object is that
5222 string as eligible for mouse highlight. Fixes mouse highlight of
5223 display strings from overlays. (Bug#10464)
5225 2012-01-07 Paul Eggert <eggert@cs.ucla.edu>
5227 emacs: fix an auto-save permissions race condition (Bug#10400)
5228 * fileio.c (auto_saving_dir_umask): New static var.
5229 (Fmake_directory_internal): Use it.
5230 (do_auto_save_make_dir): Set it, instead of invoking chmod after
5231 creating the directory. The old code temporarily assigns
5232 too-generous permissions to the directory.
5233 (do_auto_save_eh): Clear it.
5234 (Fdo_auto_save): Catch all errors, not just file errors, so
5235 that the var is always cleared.
5237 2012-01-07 Eli Zaretskii <eliz@gnu.org>
5239 * search.c (scan_buffer): Pass character positions to
5240 know_region_cache, not byte positions. (Bug#6540)
5242 2012-01-07 LynX <_LynX@bk.ru> (tiny change)
5244 * w32.c (sys_rename): Report EXDEV when rename of a directory

5738 Problem reported by Andreas Schwab in
5739 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
5740 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
5741 is set, removing the need for VIRT_ADDRESS_VARIES.
5742 (PURE_P): Use a more-efficient implementation that needs just one
5743 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
5744 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
5745 to 4 (xorl, subq, cmpq, setbe).
5746 * alloc.c (pure): Always extern now, since that's the
5747 VIRT_ADDR_VARIES behavior.
5748 (PURE_POINTER_P): Use a single comparison, not two, for
5749 consistency with the new puresize.h.
5750 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
5751 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:
5752 Remove VIRT_ADDR_VARIES no longer needed.

5757 (erase_phys_cursor, update_window_cursor, show_mouse_face)
5758 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
5759 behave as if the cursor position were at the window margin.
5761 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
5762 and the cursor position is out of bounds, behave as if the cursor
5763 position were at the window margin. (Bug#10075)
5765 2011-11-18 Chong Yidong <cyd@gnu.org>
5767 * window.c (Fwindow_combination_limit): Make first argument
5768 non-optional, since it is meaningless for live windows like the

5788 * xdisp.c (row_hash): New function, body extracted from
5789 compute_line_metrics.
5790 (compute_line_metrics): Call row_hash, instead of computing the
5791 hash code inline.
5793 * dispnew.c (verify_row_hash): Call row_hash for computing the
5794 hash code of a row, instead of duplicating code from xdisp.c.
5796 * dispextern.h (row_hash): Add prototype.
5798 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>

5834 2011-11-14 Eli Zaretskii <eliz@gnu.org>
5836 * xdisp.c (display_line): Move the call to
5837 highlight_trailing_whitespace before the call to
5838 compute_line_metrics, since the latter needs to see the final
5839 faces of all the glyphs to compute ROW's hash value.
5840 Fixes assertion violations in row_equal_p. (Bug#10035)
5842 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
5844 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,

5849 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
5850 with user-defined heap size. Bump the default size of the temacs
5851 heap to 27MB, to avoid memory warning when running temacs.
5852 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
5854 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
5855 current_matrix and desired_matrix. (Bug#9990)
5856 (verify_row_hash) [XASSERTS]: New function.
5857 (adjust_glyph_matrix, row_equal_p): Use it in xassert to verify

5901 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
5903 Avoid some portability problems by eschewing 'extern inline' functions.
5904 The trivial performance wins aren't worth the portability hassles; see
5905 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
5906 et seq.

5909 (window_box_right, window_box_right_offset): Undo previous change,
5910 by removing the "extern"s.

5913 making these static again.
5914 (offset_intervals, temp_set_point_both, temp_set_point)
5915 (copy_intervals_to_string): No longer inline.

5981 (window_box_width, window_box_left, window_box_left_offset)
5982 (window_box_right, window_box_right_offset): Declare extern.
5983 Otherwise, these inline functions do not conform to C99 and
5984 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
5985 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
5986 * intervals.c (adjust_intervals_for_insertion)
5987 (adjust_intervals_for_deletion): Now extern, because otherwise the

5989 (static_offset_intervals): Remove.
5990 (offset_intervals): Rewrite using the old contents of
5991 static_offset_intervals. The old version didn't conform to C99
5992 because an extern inline function contained a reference to an
5993 identifier with static linkage.
5995 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
5997 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

6012 (Fwindow_use_time, Fwindow_total_size, Fwindow_normal_size)
6013 (Fwindow_new_normal, Fwindow_left_column, Fwindow_top_line)
6014 (Fwindow_margins, Fwindow_fringes, Fwindow_scroll_bars)
6015 (Fwindow_vscroll): Doc fix.
6016 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default

6041 from 2011-11-05.
6043 2011-11-05 Jan Djärv <jan.h.d@swipnet.se>
6045 * nsfns.m: Declare image_cache_refcount if GLYPH_DEBUG.
6046 (unwind_create_frame): New function (Bug#9943).
6047 (Fx_create_frame): Restructure code to be more similar to the one in
6048 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).
6049 Initialize image_cache_refcount if GLYPH_DEBUG (Bug#9943).
6050 Move terminal->reference_count++ just before making the frame official
6051 (Bug#9943).
6053 * nsterm.m (x_free_frame_resources): New function.
6054 (x_destroy_window): Move code to x_free_frame_resources.
6056 * xfns.c (unwind_create_frame): Fix comment.

6064 Support MSVC build with newer versions of Visual Studio.
6065 * makefile.w32-in (TAGS-gmake): Don't use $(patsubst ...), as

6193 2011-10-28 Eli Zaretskii <eliz@gnu.org>
6195 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
6196 possible random value that matches one of those tested as
6197 condition to clear the mouse face.
6199 2011-10-28 Chong Yidong <cyd@gnu.org>
6201 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.
6203 2011-10-28 Dan Nicolaescu <dann@ics.uci.edu>
6205 * window.c (make_window): Initialize phys_cursor_on_p.
6207 2011-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
6209 * lisp.h (struct Lisp_Symbol): Update comments.
6211 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
6213 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
6215 2011-10-28 Eli Zaretskii <eliz@gnu.org>
6217 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
6218 <oslsachem@gmail.com> for helping to debug this.
6220 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
6221 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
6222 (g_b_init_get_glyph_outline_w): New static variables.
6223 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
6224 (GetGlyphOutlineW_Proc): New typedefs.
6225 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
6226 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
6227 New functions.
6228 (w32font_open_internal, compute_metrics):
6229 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
6230 instead of calling the "wide" APIs directly.
6232 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
6234 * w32.h (syms_of_w32font): Add prototype.
6236 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
6238 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
6239 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
6240 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
6241 (Fmove_to_window_line): Doc fix.
6243 2011-10-27 Chong Yidong <cyd@gnu.org>
6245 * process.c (make_process): Set gnutls_state to NULL.
6247 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
6248 non-NULL, regardless of GNUTLS_INITSTAGE.
6249 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
6250 an error. Set process slots as soon as we allocate them.
6252 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
6254 2011-10-27 Chong Yidong <cyd@gnu.org>
6256 * gnutls.c (emacs_gnutls_deinit): New function.
6257 Deallocate credentials structures as well as calling gnutls_deinit.
6258 (Fgnutls_deinit, Fgnutls_boot): Use it.
6260 * process.c (make_process): Initialize GnuTLS credentials to NULL.
6261 (deactivate_process): Call emacs_gnutls_deinit.
6263 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
6265 * image.c (x_create_x_image_and_pixmap):
6266 * w32.c (sys_rename, w32_delayed_load):
6267 * w32font.c (fill_in_logfont):
6268 * w32reg.c (x_get_string_resource): Silence compiler warnings.
6270 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
6272 * w32fns.c (w32_default_color_map): New function,
6273 extracted from Fw32_default_color_map.
6274 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
6276 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
6278 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
6280 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
6282 * keyboard.c (test_undefined): New function (bug#9751).
6283 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
6285 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
6287 * sysdep.c (init_sys_modes): Fix the check for the controlling
6288 terminal (Bug#6649).
6290 2011-10-20 Eli Zaretskii <eliz@gnu.org>
6292 * dispextern.h (struct bidi_it): New member next_en_type.
6294 * bidi.c (bidi_line_init): Initialize the next_en_type member.
6295 (bidi_resolve_explicit_1): When next_en_pos is valid for the
6296 current character, check also for next_en_type being WEAK_EN.
6297 (bidi_resolve_weak): Don't enter the expensive loop if the current
6298 position is before next_en_pos. Record the bidi type of the first
6299 non-ET, non-BN character we find, in addition to its position.
6300 (bidi_level_of_next_char): Invalidate next_en_type when
6301 next_en_pos is over-stepped.
6303 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
6305 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
6306 * editfns.c: Rewrite current-time-zone so that it invokes
6307 the equivalent of (format-time-string "%Z") to get the time zone name.
6308 This fixes a bug when the time zone name contains characters that
6309 need converting from the system time locale to Emacs internal format.
6310 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
6311 that patch fixed format-time-string to do the conversion, but
6312 I forgot to fix current-time-zone.
6313 (format_time_string): New function, containing most of
6314 what Fformat_time_string used to contain.
6315 (Fformat_time_string): Rewrite in terms of format_time_string.
6316 This doesn't change this function's behavior.
6317 (current-time-zone): Rewrite to use format_time_string.
6318 This fixes the bug reported by Michael Schierl in
6319 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
6320 Jason Rumney's 2007-06-07 change worked around this bug, but
6321 didn't fix it.
6322 * systime.h (tzname, timezone): Remove no-longer-used declarations.
6324 2011-10-19 Eli Zaretskii <eliz@gnu.org>
6326 * xdisp.c (start_display): If the character at POS is displayed
6327 via a display vector, reset IT->current.dpvec_index to zero.
6328 (try_window_reusing_current_matrix): If a line ends in a display
6329 vector or the next line starts in a display vector, continue
6330 redrawing the window even though the character position of
6331 start_row was reached.
6332 (Bug#9771, part 2)
6334 2011-10-18 Chong Yidong <cyd@gnu.org>
6336 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
6337 with nobreak-char-display too.
6339 2011-10-18 Eli Zaretskii <eliz@gnu.org>
6341 Fix part 3 of bug#9771.
6342 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
6343 (bidi_resolve_neutral): Don't enter the expensive loop looking for
6344 non-neutral characters if the current character is a paragraph
6345 separator (a.k.a. Newline). This avoids running the same
6346 expensive loop twice, once when we consume the preceding newline
6347 and the other time when the line actually needs to be displayed.
6348 Avoid the loop when we see neutrals on the base embedding level
6349 following a character whose directionality is the same as the
6350 paragraph's. This avoids running the expensive loop when a line
6351 ends in a long sequence of neutrals, like control characters.
6352 Add assertion against STRONG_AL type. Slightly rearrange code
6353 that determines the type of a neutral given the first non-neutral
6354 that follows it.
6355 (bidi_level_of_next_char): Set next_en_pos to zero when
6356 invalidating its info.
6358 2011-10-17 Eli Zaretskii <eliz@gnu.org>
6360 * xdisp.c (push_display_prop): Determine whether to record string
6361 or buffer position by IT->string, not by IT->method. Allow
6362 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
6363 (move_it_vertically_backward): Don't look for character position
6364 immediately after the newline when in a continuation line.
6365 (Bug#9771, part 1)
6367 2011-10-15 Martin Rudalics <rudalics@gmx.at>
6369 * window.c (coordinates_in_window): Rewrite and delabelize
6370 vertical border check. (Bug#5357) (Bug#9618)
6372 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
6374 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
6375 errors in XSetWindowBorder (bug#9310).
6377 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
6379 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
6380 avoid crash when xmalloc overrun checking is enabled.
6382 2011-10-13 Eli Zaretskii <eliz@gnu.org>
6384 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
6385 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
6386 cursor motion with <left> and <right> arrow keys.
6388 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
6389 some callers set that themselves.
6391 2011-10-12 Eli Zaretskii <eliz@gnu.org>
6393 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
6394 display string and the previous row comes from the same string and
6395 is empty. (Bug#9739) (Bug#9738)
6397 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
6399 * doc.c (get_doc_string): Encode file name (bug#9735).
6401 2011-10-12 Eli Zaretskii <eliz@gnu.org>
6403 * bidi.c (bidi_level_of_next_char):
6404 * xdisp.c (get_visually_first_element): Remove old incorrect
6405 comments regarding the Unicode Line Separator character.
6407 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
6409 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
6411 * alloc.c (Fgc_status): Do not access beyond zombies array
6412 boundary if nzombies > MAX_ZOMBIES.
6413 * alloc.c (dump_zombies): Add missing format specifier.
6415 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
6417 * xdisp.c (set_cursor_from_row): Simplify conditionals,
6418 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
6420 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
6421 Some packages use them to denote characters with modifiers.
6423 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
6425 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
6426 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
6427 matching a pp-number. Rename parameter var to var1.
6429 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
6431 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
6433 2011-10-08 Glenn Morris <rgm@gnu.org>
6435 * callint.c (Fcall_interactively): Give a more explicit error for the
6436 'c' case with a non-character input. (Bug#8479)
6438 2011-10-08 Eli Zaretskii <eliz@gnu.org>
6440 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
6441 lines.
6442 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
6443 lines that are hscrolled on the left.
6445 * dispnew.c (buffer_posn_from_coords): Account for a possible
6446 presence of header-line. (Bug#4426)
6448 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
6450 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
6451 Don't advertise functionality which we discourage or doesn't work.
6453 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
6455 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
6456 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
6457 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
6458 this makes Emacs dump core during garbage collection on rare
6459 occasions. sizeof is obviously inferior to offsetof here, so
6460 stick with offsetof.
6461 (GC_POINTER_ALIGNMENT): New macro.
6462 (mark_memory): Omit 3rd (offset) arg; caller changed.
6463 Don't assume EMACS_INT alignment is the same as pointer alignment.
6465 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
6467 * keyboard.c (read_key_sequence_remapped): New var.
6468 (read_key_sequence): Compute remapping in the right buffer.
6469 (command_loop_1): Use read_key_sequence's remapping directly.
6471 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
6473 * dired.c (file_name_completion): Don't expand file name.
6474 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
6475 before checking file name handler.
6477 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
6478 they've been requested explicitly (bug#9591).
6480 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
6482 * keymap.c (Fsingle_key_description): Use make_specified_string
6483 instead of build_string to build string from push_key_description.
6484 (Bug#5193)
6486 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
6488 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
6489 This fixes a Y2038 bug on 64-bit hosts.
6490 * buffer.c (reset_buffer):
6491 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
6492 (Fclear_buffer_auto_save_failure):
6493 Use 0, not -1, to represent an unset failure time, since time_t
6494 might not be signed.
6496 Remove dependency on glibc malloc internals.
6497 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6498 Move back here from lisp.h, but with their new implementations.
6499 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
6500 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
6501 * charset.c (charset_table_init): New static var.
6502 (syms_of_charset): Use it instead of xmalloc. This removes a
6503 dependency on glibc malloc internals. See Eli Zaretskii's comment in
6504 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
6505 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6506 Move back to alloc.c.
6507 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
6508 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
6510 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
6512 * nsterm.m (windowDidResize): Call x_set_window_size only when
6513 ns_in_resize is true. Otherwise set pixelwidth/height and
6514 call change_frame_size (Bug#9628).
6516 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
6518 Port --enable-checking=all to Fedora 14 x86-64.
6519 * charset.c (syms_of_charset): Also account for glibc malloc's
6520 internal overhead when calculating the initial malloc maximum.
6522 Port --enable-checking=all to Fedora 14 x86.
6523 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6524 Move to lisp.h.
6525 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
6526 (overrun_check_realloc, overrun_check_free):
6527 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
6528 That way, xmalloc returns a properly-aligned pointer even if
6529 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
6530 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
6531 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
6532 into account when calculating the initial malloc maximum.
6533 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6534 Move here from alloc.c, so that charset.c can use it too.
6535 Properly align; the old code wasn't right for common 32-bit hosts
6536 when configured with --enable-checking=all.
6537 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
6538 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
6540 2011-09-29 Eli Zaretskii <eliz@gnu.org>
6542 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
6543 use EDOM.
6545 2011-09-28 Eli Zaretskii <eliz@gnu.org>
6547 * xdisp.c (compute_display_string_end): If there's no display
6548 string at CHARPOS, return -1.
6550 * bidi.c (bidi_fetch_char): When compute_display_string_end
6551 returns a negative value, treat the character as a normal
6552 character not covered by a display string. (Bug#9624)
6554 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
6556 * lread.c (Fread_from_string): Fix typo in docstring.
6558 2011-09-27 Eli Zaretskii <eliz@gnu.org>
6560 * xdisp.c (handle_invisible_prop): If invisible text ends on a
6561 newline, reseat the iterator instead of bidi-iterating there one
6562 character at a time. (Bug#9610)
6563 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
6564 TO_CHARPOS if the bidi iterator is at base embedding level.
6566 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
6568 * lread.c (readevalloop): Use correct code for NBSP.
6569 (read1): Likewise. (Bug#9608)
6571 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
6573 * dbusbind.c (Fdbus_register_signal): When service is not
6574 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
6576 2011-09-25 Glenn Morris <rgm@gnu.org>
6578 * buffer.c (truncate-lines): Doc fix.
6580 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
6582 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
6583 (Fset_window_next_buffers): Doc fix.
6585 2011-09-24 Glenn Morris <rgm@gnu.org>
6587 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
6589 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
6591 Fix minor problems found by static checking.
6592 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
6593 * indent.c (Fvertical_motion): Fix == vs = typo.
6595 2011-09-24 Eli Zaretskii <eliz@gnu.org>
6597 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
6598 Default value is now t. Doc fix.
6600 * indent.c (Fvertical_motion): Compute and apply the overshoot
6601 logic when moving up, not only when moving down. Fix the
6602 confusing name and values of the it_overshoot_expected variable;
6603 logic changes accordingly. (Bug#9254) (Bug#9549)
6605 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
6606 CHARPOS is covered by a display string which includes newlines.
6607 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
6608 is covered by a display string with embedded newlines.
6610 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
6612 * dbusbind.c (Fdbus_register_signal): Add match rule to
6613 Vdbus_registered_objects_table. (Bug#9581)
6614 (Fdbus_register_method, Vdbus_registered_objects_table):
6615 Fix docstring.
6617 2011-09-24 Jim Meyering <meyering@redhat.com>
6619 do not ignore write error for any output size
6620 The previous change was incomplete.
6621 While it makes emacs --batch detect the vast majority of stdout
6622 write failures, errors were still ignored whenever the output size is
6623 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
6624 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
6625 && echo FAIL: ignored write error
6626 FAIL: ignored write error
6627 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
6628 && echo FAIL: ignored write error
6629 FAIL: ignored write error
6630 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
6632 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
6634 * emacs.c (Fkill_emacs): In noninteractive mode exit
6635 non-successfully if a write error occurred on stdout. (Bug#9574)
6637 2011-09-21 Eli Zaretskii <eliz@gnu.org>
6639 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
6640 the xassert test.
6642 * dispextern.h (struct it): Update the comment documenting what
6643 can it->OBJECT be.
6645 2011-09-20 Eli Zaretskii <eliz@gnu.org>
6647 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
6648 a display string, extend search for cursor position to end of row.
6649 (find_row_edges): If the row ends in a newline from a display
6650 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
6651 Handle the case of a display string with multiple newlines.
6652 (Fcurrent_bidi_paragraph_direction): Fix search for previous
6653 non-empty line. Fixes confusing cursor motion with arrow keys at
6654 the beginning of a line that starts with whitespace.
6656 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
6658 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
6659 (bug#9493).
6661 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
6663 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
6664 boolean (Bug#9154).
6666 2011-09-18 Eli Zaretskii <eliz@gnu.org>
6668 * xdisp.c (display_line): Record maximum and minimum buffer
6669 positions even if no glyphs were produced (e.g., by a zero-width
6670 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
6671 buffer positions that will be removed from the glyph row because
6672 they don't fit.
6673 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
6674 column is beyond frame width: don't subtract 1 "pixel" when
6675 computing width of the stretch.
6676 (reseat_at_next_visible_line_start): Undo the change made on
6677 2011-09-17 that saved paragraph information and restored it after
6678 the call to `reseat'. (Bug#9545)
6680 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6682 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
6683 and turn window cursor on if cleared (Bug#9415).
6685 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
6687 * search.c (boyer_moore): Take unibyte characters from pattern
6688 literally. (Bug#9458)
6690 2011-09-18 Eli Zaretskii <eliz@gnu.org>
6692 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
6694 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
6696 Fix minor problem found by static checking.
6697 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
6698 initialized, to pacify gcc -Wuninitialized.
6700 * fileio.c: Report proper errno when syscall falls.
6701 (Finsert_file_contents): Save and restore errno,
6702 so that report_file_error outputs the correct diagnostic.
6703 (Fwrite_region) [CLASH_DETECTION]: Likewise.
6705 2011-09-18 Eli Zaretskii <eliz@gnu.org>
6707 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
6709 2011-09-17 Eli Zaretskii <eliz@gnu.org>
6711 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
6712 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
6714 2011-09-17 Eli Zaretskii <eliz@gnu.org>
6716 * xdisp.c (reseat_at_next_visible_line_start): Keep information
6717 about the current paragraph and restore it after the call to reseat.
6719 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
6720 (bidi_find_paragraph_start): Search back for paragraph beginning
6721 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
6722 (bidi_move_to_visually_next): Only trigger paragraph-related
6723 computations when the last character is a newline or at EOB, not
6724 just any NEUTRAL_B. (Bug#9470)
6726 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
6727 truncated lines if point is covered by a display string. (Bug#9524)
6729 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
6731 * xselect.c: Relax test for outgoing X longs (Bug#9498).
6732 (cons_to_x_long): New function.
6733 (lisp_data_to_selection_data): Use it. Correct the test for
6734 short-versus-long data; it was negated. Break out of vector
6735 loop, for efficiency, when a long datum is discovered.
6737 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
6739 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
6741 2011-09-16 Eli Zaretskii <eliz@gnu.org>
6743 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
6744 GCC PR/17406) by declaring this function with external scope.
6746 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
6748 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
6749 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
6751 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
6753 * editfns.c (Fformat): Correctly handle text properties on "%%".
6755 2011-09-15 Eli Zaretskii <eliz@gnu.org>
6757 * xterm.c (x_draw_composite_glyph_string_foreground):
6758 * w32term.c (x_draw_composite_glyph_string_foreground):
6759 * term.c (encode_terminal_code):
6760 * composite.c (composition_update_it, get_composition_id):
6761 * xdisp.c (get_next_display_element)
6762 (fill_composite_glyph_string): Add comments about special meaning
6763 of TAB characters in a composition.
6765 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
6767 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
6768 This occurs when processing a multibyte format.
6769 Problem reported by Wolfgang Jenker.
6771 2011-09-15 Johan Bockgård <bojohan@gnu.org>
6773 * xdisp.c (try_cursor_movement): Only check for exact match if
6774 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
6776 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
6778 Remove unused external symbols.
6779 * dispextern.h (calc_pixel_width_or_height): Remove decl.
6780 * xdisp.c (calc_pixel_width_or_height): Now static.
6781 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
6782 * indent.c (check_display_width):
6783 * w32term.c: Fix comment to match code.
6784 * xterm.c, xterm.h (x_catching_errors): Remove.
6786 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
6788 * xselect.c: Use signed conversions more consistently (Bug#9498).
6789 (selection_data_to_lisp_data): Assume incoming selection data are
6790 signed integers, not unsigned. This is to be consistent with
6791 outgoing selection data, which was modified to use signed integers
6792 in as part of the fix to Bug#9196 in response to Jan D.'s comment
6793 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
6794 expects long, not unsigned long.
6796 2011-09-14 Eli Zaretskii <eliz@gnu.org>
6798 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
6799 computation of loop end. Reported by Johan Bockgård
6800 <bojohan@gnu.org>.
6802 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
6804 * frame.c (Fother_visible_frames_p): Function deleted.
6806 2011-09-12 Eli Zaretskii <eliz@gnu.org>
6808 * indent.c (compute_motion): Process display vector front to back
6809 rather than the other way around. (Bug#2496)
6811 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
6813 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
6815 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
6817 * minibuf.c (Fread_from_minibuffer): Doc fix.
6819 2011-09-11 Eli Zaretskii <eliz@gnu.org>
6821 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
6822 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
6824 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
6826 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
6827 value for non-existent files.
6829 2011-09-11 Eli Zaretskii <eliz@gnu.org>
6831 * fileio.c (Finsert_file_contents): If the file cannot be opened,
6832 set its "size" to -1. This will set the modtime_size field of
6833 the corresponding buffer to -1, which is what
6834 verify-visited-file-modtime expects for files that do not exist.
6835 (Bug#9139)
6837 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
6839 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
6840 here ...
6841 * lisp.h: ... from here. push_key_description is no longer
6842 defined in keyboard.c, so its declaration should not be in
6843 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
6844 logically belongs with push_key_description.
6846 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
6848 * buffer.h: Include <sys/types.h> instead of <time.h>.
6849 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
6850 Problem reported by Herbert J. Skuhra.
6852 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
6854 * xml.c (parse_region): Make the parsing work for
6855 non-comment-starting XML files again (bug#9144).
6857 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
6859 * image.c (gif_load): Fix calculation of bottom and right corner.
6860 (Bug#9468)
6862 2011-09-10 Eli Zaretskii <eliz@gnu.org>
6864 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
6865 redisplay in small windows.
6867 2011-09-09 Eli Zaretskii <eliz@gnu.org>
6869 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
6871 2011-09-08 Martin Rudalics <rudalics@gmx.at>
6873 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
6874 Operate on live windows only.
6876 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
6878 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
6880 2011-09-07 Eli Zaretskii <eliz@gnu.org>
6882 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
6883 only under bidi iteration.
6885 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
6887 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
6889 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
6891 isnan: Fix porting problem to Solaris 10 with bundled gcc.
6892 Without this fix, the command to link temacs failed due to an
6893 undefined symbol __builtin_isnan. This is because
6894 /usr/include/iso/math_c99.h #defines isnan(x) to
6895 __builtin_isnan(x), but the bundled gcc, which identifies itself
6896 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
6897 a __builtin_isnan.
6898 * floatfns.c (isnan): #undef, and then #define to a clone of
6899 what's in data.c.
6900 (Fisnan): Always define, since it's always available now.
6901 (syms_of_floatfns): Always define isnan at the Lisp level.
6903 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
6905 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
6907 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
6909 * fileio.c: Fix bugs with large file offsets (Bug#9428).
6910 The previous code assumed that file offsets (off_t values) fit in
6911 EMACS_INT variables, which is not true on typical 32-bit hosts.
6912 The code messed up by falsely reporting buffer overflow in cases
6913 such as (insert-file-contents "big" nil 1 2) into an empty buffer
6914 when "big" contains more than 2**29 bytes, even though this
6915 inserts just one byte and does not overflow the buffer.
6916 (Finsert_file_contents): Store file offsets as off_t
6917 values, not as EMACS_INT values. Check for overflow when
6918 converting between EMACS_INT and off_t. When checking for
6919 buffer overflow or for overlap, take the offsets into account.
6920 Don't use EMACS_INT for small values where int suffices.
6921 When checking for overlap, fix a typo: ZV was used where
6922 ZV_BYTE was intended.
6923 (Fwrite_region): Don't assume off_t fits into 'long'.
6924 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
6926 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
6928 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
6930 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
6932 sprintf-related integer and memory overflow issues (Bug#9412).
6934 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
6935 (esprintf, exprintf, evxprintf): New functions.
6936 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
6937 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
6938 (modify_event_symbol): Do not assume that the length of
6939 name_alist_or_stem is safe to alloca and fits in int.
6940 (Fexecute_extended_command): Likewise for function name and binding.
6941 (Frecursion_depth): Wrap around reliably on integer overflow.
6942 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
6943 since some callers pass EMACS_INT values.
6944 (Fsingle_key_description): Don't crash if symbol name contains more
6945 than MAX_ALLOCA bytes.
6946 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
6947 (get_minibuffer): Arg is now EMACS_INT, not int.
6948 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
6949 (esprintf, exprintf, evxprintf): New decls.
6950 * window.h (command_loop_level, minibuf_level): Reflect API changes.
6952 * dbusbind.c (signature_cat): New function.
6953 (xd_signature, Fdbus_register_signal):
6954 Do not overrun buffer; instead, report string overflow.
6956 * dispnew.c (add_window_display_history): Don't overrun buffer.
6957 Truncate instead; this is OK since it's just a log.
6959 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
6960 even if the time zone offset is outlandishly large.
6961 Don't mishandle offset == INT_MIN.
6963 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
6964 when creating daemon; the previous buffer-overflow check was incorrect.
6966 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
6967 which has the guts of the old verror function.
6969 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
6970 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
6972 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
6973 (font_unparse_xlfd): Don't blindly alloca long strings.
6974 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
6975 fits in int, when using sprintf. Use single snprintf to count
6976 length of string rather than counting it via multiple sprintfs;
6977 that's simpler and more reliable.
6978 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
6979 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
6980 sprintf, in case result does not fit in int.
6982 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
6983 (fontset_from_font): Print it.
6985 * frame.c (tty_frame_count): Now printmax_t, not int.
6986 (make_terminal_frame, set_term_frame_name): Print it.
6987 (x_report_frame_params): In X, window IDs are unsigned long,
6988 not signed long, so print them as unsigned.
6989 (validate_x_resource_name): Check for implausibly long names,
6990 and don't assume name length fits in 'int'.
6991 (x_get_resource_string): Don't blindly alloca invocation name;
6992 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
6993 not fit in int.
6995 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
6996 (xg_check_special_colors, xg_set_geometry):
6997 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
6999 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
7000 Use esprintf, not sprintf, in case result does not fit in int.
7002 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7003 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
7004 it as a large positive number.
7005 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
7006 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7008 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
7009 in case result does not fit in int.
7011 * print.c (float_to_string): Detect width overflow more reliably.
7012 (print_object): Make sprintf buffer a bit bigger, to avoid potential
7013 buffer overrun. Don't assume list length fits in 'int'. Treat
7014 print length of 0 as 0, not as infinity; to be consistent with other
7015 uses of print length in this function. Don't overflow print length
7016 index. Don't assume hash table size fits in 'long', or that
7017 vectorlike size fits in 'unsigned long'.
7019 * process.c (make_process): Use printmax_t, not int, to format
7020 process-name gensyms.
7022 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
7024 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
7025 to avoid potential buffer overrun.
7027 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
7028 if X resource line is longer than 512 bytes.
7030 * xfns.c (x_window): Make sprintf buffer a bit bigger
7031 to avoid potential buffer overrun.
7033 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
7035 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
7037 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7039 Integer overflow fixes for scrolling, etc.
7040 Without these, Emacs silently mishandles large integers sometimes.
7041 For example, "C-u 4294967297 M-x recenter" was treated as if
7042 it were "C-u 1 M-x recenter" on a typical 64-bit host.
7044 * xdisp.c (try_window_id): Check Emacs fixnum range before
7045 converting to 'int'.
7047 * window.c (window_scroll_line_based, Frecenter):
7048 Check that an Emacs fixnum is in range before assigning it to 'int'.
7049 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
7050 values converted from Emacs fixnums.
7051 (Frecenter): Don't wrap around a line count if it is out of 'int'
7052 range; instead, treat it as an extreme value.
7053 (Fset_window_configuration, compare_window_configurations):
7054 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
7056 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
7057 that can exceed INT_MAX. Check that EMACS_INT value is in range
7058 before assigning it to the (possibly-narrower) index.
7059 (match_limit): Don't assume that a fixnum can fit in 'int'.
7061 * print.c (print_object): Use ptrdiff_t, not int, for index that can
7062 exceed INT_MAX.
7064 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
7065 (Fvertical_motion): Don't wrap around LINES values that don't fit
7066 in 'int'. Instead, treat them as extreme values. This is good
7067 enough for windows, which can't have more than INT_MAX lines anyway.
7069 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
7071 * Require libxml/parser.h to avoid compilation warning.
7073 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
7075 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
7076 since this reportedly can destroy thread storage.
7078 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
7080 * syntax.c (find_defun_start): Update all cache variables if
7081 exiting early (Bug#9401).
7083 2011-08-30 Eli Zaretskii <eliz@gnu.org>
7085 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
7087 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
7088 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
7089 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
7091 * term.c (tty_append_glyph): New function.
7092 (produce_stretch_glyph): Static function and its prototype deleted.
7094 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
7095 Add prototypes.
7097 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
7099 * image.c (parse_image_spec): Check for nonnegative, not for positive,
7100 when checking :margin (Bug#9390).
7101 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
7102 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
7103 so that the name doesn't mislead. All uses changed.
7105 2011-08-28 Johan Bockgård <bojohan@gnu.org>
7107 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
7108 set_tty_hooks.
7110 2011-08-27 Eli Zaretskii <eliz@gnu.org>
7112 * xdisp.c (move_it_to): Don't bail out early when reaching
7113 position beyond to_charpos, if we are scanning backwards.
7114 (move_it_vertically_backward): When DY == 0, make sure we get to
7115 the first character in the line after the newline.
7117 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
7119 * ccl.c: Improve and simplify overflow checking (Bug#9196).
7120 (ccl_driver): Do not generate an out-of-range pointer.
7121 (Fccl_execute_on_string): Remove unnecessary check for
7122 integer overflow, noted by Stefan Monnier in
7123 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
7124 Remove a FIXME that didn't need fixing.
7125 Simplify the newly-introduced buffer reallocation code.
7127 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
7129 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
7131 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
7133 Integer and memory overflow issues (Bug#9196).
7135 * doc.c (get_doc_string): Rework so that
7136 get_doc_string_buffer_size is the actual buffer size, rather than
7137 being 1 less than the actual buffer size; this makes xpalloc more
7138 convenient.
7140 * image.c (x_allocate_bitmap_record, cache_image):
7141 * xselect.c (Fx_register_dnd_atom):
7142 Simplify previous changes by using xpalloc.
7144 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
7145 since either will do and ptrdiff_t is convenient with xpalloc.
7147 * charset.c (charset_table_size)
7148 (struct charset_sort_data.priority): Now ptrdiff_t.
7149 (charset_compare): Don't overflow if priorities differ greatly.
7150 (Fsort_charsets): Don't assume list length fits in int.
7151 Check for size-calculation overflow when allocating sort data.
7152 (syms_of_charset): Allocate an initial charset table that is
7153 just under 64 KiB, to avoid problems with glibc malloc and mmap.
7155 * cmds.c (internal_self_insert): Check for size-calculation overflow.
7157 * composite.h (struct composition.glyph_len): Now int, not unsigned.
7158 The actual value is always <= INT_MAX, and leaving it unsigned made
7159 overflow checking harder.
7161 * dispextern.h (struct glyph_matrix.rows_allocated)
7162 (struct face_cache.size): Now ptrdiff_t, for convenience in use
7163 with xpalloc. The values are still always <= INT_MAX.
7165 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
7167 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
7168 (SAFE_NALLOCA): New macro.
7170 * region-cache.c (struct boundary.pos, find_cache_boundary)
7171 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
7172 (set_cache_region, invalidate_region_cache)
7173 (revalidate_region_cache, know_region_cache, region_cache_forward)
7174 (region_cache_backward, pp_cache):
7175 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
7176 so that ptrdiff_t * can be passed to xpalloc.
7177 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
7178 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
7179 (pp_cache): Don't assume cache_len fits in int.
7180 * region-cache.h: Adjust extern decls to match.
7182 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
7183 EMACS_INT, since either will do, for xpalloc.
7185 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
7186 (xnmalloc, xnrealloc, xpalloc): New functions.
7188 * bidi.c (bidi_shelve_header_size): New constant.
7189 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
7190 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
7192 * bidi.c (bidi_cache_shrink):
7193 * buffer.c (overlays_at, overlays_in, record_overlay_string)
7194 (overlay_strings):
7195 Don't update size of array until after memory allocation succeeds,
7196 because xmalloc/xrealloc may not return.
7197 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
7198 now that we have proper integer overflow checking.
7199 (record_overlay_string, overlay_strings): Catch overflows when
7200 calculating size of overlay_str_buf.
7202 * callproc.c (Fcall_process): Check for size overflow when
7203 calculating size of args2.
7204 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
7205 Normally we prefer signed values, but sticking with ptrdiff_t would
7206 require adding more-complicated checks.
7208 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
7209 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
7210 Redo buffer-overflow calculations to avoid integer overflow.
7211 Add a FIXME comment where memory seems to be over-allocated.
7213 * character.c (Fstring): Check for size-calculation overflow.
7215 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
7216 unnecessary integer overflow. Check for size overflow.
7217 (encode_coding_object): Don't update size until xmalloc succeeds.
7219 * composite.c (get_composition_id): Check for overflow in glyph
7220 length calculations.
7222 Integer and memory overflow fixes for display code.
7223 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
7224 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
7225 (scrolling_window): Check for overflow in size calculations.
7226 (line_draw_cost, realloc_glyph_pool, add_row_entry):

7238 (get_doc_string): Check for size calculation overflow.
7239 Don't update size until allocation succeeds.
7240 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
7241 EMACS_INT, where ptrdiff_t will do.
7242 (Fsubstitute_command_keys): Check for string overflow.
7244 * editfns.c (set_time_zone_rule): Don't assume environment length
7245 fits in int.
7246 (message_length): Now ptrdiff_t, not int.
7247 (Fmessage_box): Don't update size until allocation succeeds.
7248 Don't assume message length fits in int.
7249 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
7251 * emacs.c (main): Do not reallocate argv, since there is a null at
7252 the end that can be overwritten, and this way there's no need to
7253 worry about size-calculation overflow.
7254 (sort_args): Check for size-calculation overflow.
7256 * eval.c (init_eval_once, grow_specpdl): Don't update size until
7257 alloc succeeds.
7258 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
7260 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
7261 (x_set_scroll_bar_width, x_figure_window_size):
7262 Check for integer overflow.
7263 (x_set_alpha): Do not assume XINT fits in int.
7265 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
7266 This is for the members text_lines, text_cols, total_lines, total_cols,
7267 where the system imposes an 'int' limit.
7269 * fringe.c (Fdefine_fringe_bitmap):
7270 Don't update size until alloc works.
7272 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
7273 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
7275 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
7276 Check for size-calculation overflow.
7277 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
7278 do, as we prefer signed integers.
7279 (id_to_widget.max_size, id_to_widget.used)
7280 (xg_store_widget_in_map, xg_remove_widget_from_map)
7281 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
7282 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
7283 Use and return ptrdiff_t, not int.
7284 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
7285 * gtkutil.h: Change prototypes to match the above.
7287 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
7288 are duplicate now that they've been promoted to lisp.h.
7289 (x_allocate_bitmap_record, x_alloc_image_color)
7290 (make_image_cache, cache_image, xpm_load):
7291 Don't update size until alloc is done.

7301 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
7302 Use ptrdiff_t, not int, to count maps.
7303 (read_char_minibuf_menu_prompt): Check for overflow in size
7304 calculations. Don't update size until allocation succeeds.
7305 Redo calculations to avoid overflow.
7306 * keyboard.h: Change prototypes to match the above.

7315 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.
7316 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.

7332 (Fset_match_data): Don't assume list lengths fit in 'int'.
7334 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
7335 for command line length. Do not attempt to address one before the
7336 beginning of an array, as that's not portable.
7338 * term.c (max_frame_lines): Remove; unused.
7339 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
7340 not int.

7344 table lengths and related sizes. Don't update size until alloc
7345 done. Redo calculations to avoid overflow.
7346 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
7348 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
7349 subtracting pointers.

7364 Use ptrdiff_t, not int, for sizes.
7365 (Finternal_make_lisp_face, cache_face):
7366 Check for size calculation overflow.
7367 (cache_face): Treat size calculation overflows as if they were
7368 memory exhaustion (the usual treatment), rather than aborting.
7370 * xfns.c (x_encode_text, x_set_name_internal)
7371 (Fx_change_window_property): Use ptrdiff_t, not int, to count
7372 sizes, since they can exceed INT_MAX in size. Check for size

7376 (xg_select): Check for size calculation overflow.
7377 Don't update size until alloc done.
7379 * xrdb.c (get_environ_db): Don't assume path length fits in int,

7382 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
7383 (X_LONG_MIN): New macros.
7384 Use them to make the following changes clearer.
7385 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
7386 This change doesn't affect the value now, but it may help remind
7387 future maintainers not to raise the value too much later.
7388 (SELECTION_QUANTUM): Remove, replacing with ...
7389 (selection_quantum): ... new function, which avoids overflow.
7390 All uses changed.
7391 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
7392 assumption that selection length fits in 'int'.
7393 (x_reply_selection_request, x_handle_selection_request)
7394 (x_get_window_property, receive_incremental_selection)
7395 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)

7400 Redo calculations to avoid overflow.
7401 (x_reply_selection_request): When sending hint, ceiling it at
7402 X_LONG_MAX rather than relying on wraparound overflow to send
7403 something.
7404 (x_get_window_property, receive_incremental_selection)
7405 (lisp_data_to_selection_data, x_property_data_to_lisp):
7406 Check for size-calculation overflow.
7407 (x_get_window_property, receive_incremental_selection)

7409 Don't store size until memory allocation succeeds.
7410 (x_get_window_property): Plug memory leak on memory exhaustion.
7411 Don't double-block input; malloc is safe here. Don't assume 2**34
7412 - 4 fits in unsigned long. Add an xassert to check
7413 XGetWindowProperty overflow. Be more careful about overflow
7414 calculations, and distinguish size from memory overflow better.
7415 (receive_incremental_selection): When tracing, don't assume
7416 unsigned int is less than INT_MAX.
7417 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
7418 harmful) conversions of unsigned short to int.
7419 (lisp_data_to_selection_data): Don't assume that integers
7420 in the range -65535 through -1 fit in an X unsigned short.
7421 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
7422 result parameters unless successful. Rely on cons_to_unsigned
7423 to report problems with elements; the old code wasn't right anyway.
7424 (x_check_property_data): Check for int overflow; we cannot use
7425 a wider type due to X limits.
7426 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
7428 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.

7436 to int size).
7438 Use ptrdiff_t for composition IDs.
7439 * character.c (lisp_string_width):
7440 * composite.c (composition_table_size, n_compositions)

7457 * image.c (xpm_get_color_table_h):
7458 * lisp.h (hash_lookup, hash_put):
7459 * minibuf.c (Ftest_completion):
7460 Use ptrdiff_t for hash table indexes, not int (which is too
7461 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
7462 32-bit --with-wide-int hosts).
7464 * charset.c (Fdefine_charset_internal): Check for integer overflow.
7465 Add a FIXME comment about memory leaks.
7466 (syms_of_charset): Don't assume xmalloc returns.
7468 Don't assume that stated character widths fit in int.
7469 * character.c (Fchar_width, c_string_width, lisp_string_width):
7470 * character.h (CHAR_WIDTH):
7471 * indent.c (MULTIBYTE_BYTES_WIDTH):
7472 Use sanitize_char_width to avoid undefined and/or bad behavior
7473 with outlandish widths.
7474 * character.h (sanitize_tab_width): Rename from sanitize_width,
7475 now that we have two such functions. All uses changed.
7476 (sanitize_char_width): New inline function.
7478 Don't assume that tab-width fits in int.
7479 * character.h (sanitize_width): New inline function.
7480 (SANE_TAB_WIDTH): New macro.

7484 * xdisp.c (init_iterator): Use SANE_TAB_WIDTH.
7486 * fileio.c: Integer overflow issues with file modes.
7487 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.

7494 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
7495 (x_send_scroll_bar_event): Likewise. Check that the size does not
7496 exceed limits imposed by XClientMessageEvent, as well as the usual
7497 ptrdiff_t and size_t limits.
7499 * keyboard.c: Overflow, signedness and related fixes.
7500 (make_lispy_movement): Use same integer type in forward decl
7501 that is used in the definition.
7502 (read_key_sequence, keyremap_step):
7503 Change bufsize argument back to int, undoing my 2011-03-30 change.
7504 We prefer signed types, and int is wide enough here.
7505 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
7506 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
7507 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
7508 length, not size_t. Use ptrdiff_t for index, not int.
7509 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
7510 possibility of integer overflow.
7512 Overflow, signedness and related fixes for images.
7514 * dispextern.h (struct it.stack[0].u.image.image_id)

7521 * nsmenu.m (update_frame_tool_bar):
7522 * xdisp.c (calc_pixel_width_or_height):
7523 * xfns.c (image_cache_refcount):
7524 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
7525 on typical 64-bit hosts.
7527 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
7528 (x_bitmap_pixmap, x_create_x_image_and_pixmap):

7533 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
7534 (lookup_image): Remove unnecessary tests.
7535 (xbm_image_p): Locals are now of int, not EMACS_INT,
7536 since parse_image_check makes sure they fit into int.
7537 (png_load, gif_load, svg_load_image):
7538 Prefer int to unsigned where either will do.
7539 (tiff_handler): New function, combining the cores of the
7540 old tiff_error_handler and tiff_warning_handler.
7541 This function is rewritten to use vsnprintf and thereby avoid
7542 stack buffer overflows. It uses only the features of vsnprintf
7543 that are common to both POSIX and native Microsoft.
7544 (tiff_error_handler, tiff_warning_handler): Use it.
7545 (tiff_load, gif_load, imagemagick_load_image):
7546 Don't assume :index value fits in 'int'.
7547 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
7548 (imagemagick_load_image): Check that crop parameters fit into
7549 the integer types that MagickCropImage accepts. Don't assume
7550 Vimagemagick_render_type has a nonnegative value. Don't assume
7551 size_t fits in 'long'.
7552 (gs_load): Use printmax_t to print the widest integers possible.
7553 Check for integer overflow when computing image height and width.
7555 2011-08-26 Eli Zaretskii <eliz@gnu.org>
7557 * xdisp.c (redisplay_window): Don't force window start if point
7558 will be invisible in the resulting window. (Bug#9324)
7560 2011-08-25 Eli Zaretskii <eliz@gnu.org>
7562 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
7563 the display spec is of the form `(space ...)'.
7564 (handle_display_spec): Return the value returned by
7565 handle_single_display_spec, not just 1 or zero.
7566 (handle_single_display_spec): If the display spec is of the form
7567 `(space ...)', and specifies display in the text area, return 2
7568 rather than 1.
7569 (try_cursor_movement): Check for the need to scroll more
7570 accurately, and prefer exact match for point under bidi.
7571 Don't advance `row' beyond the last row of the window.
7573 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
7574 into disp_prop; all users changed.
7576 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
7577 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
7578 for the text covered by the display property.
7580 2011-08-25 Chong Yidong <cyd@stupidchicken.com>
7582 * buffer.c (Fbury_buffer_internal): Rename from Funrecord_buffer.

7588 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
7589 buffers, return left-to-right.
7590 (set_cursor_from_row): Consider candidate row a win if its glyph
7591 represents a newline and point is on that newline. Fixes cursor
7592 positioning on the newline at EOL of R2L text within L2R
7593 paragraph, and vice versa.
7594 (try_cursor_movement): Check continued rows, in addition to
7595 continuation rows. Fixes unwarranted scroll when point enters a
7596 continued line of R2L text within an L2R paragraph, or vice versa.
7597 (cursor_row_p): Consider the case of point being equal to
7598 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
7599 from the end of a short line to the beginning of a continued line
7600 of R2L text within L2R paragraph.
7601 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for

7620 extra slot even if the purpose is char-code-property-table.
7622 2011-08-23 Eli Zaretskii <eliz@gnu.org>
7624 * xdisp.c (redisplay_window): When computing centering_position,
7625 account for the height of the header line. (Bug#8874)
7627 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
7628 instead of CHAR_TO_BYTE. Fixes a crash when a completion
7629 candidate is selected by the mouse, and that candidate has a
7630 composed character under the mouse.
7632 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
7633 coordinates reported by pos-visible-in-window-p for a composed
7634 character in column zero.
7636 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

7640 2011-08-22 Eli Zaretskii <eliz@gnu.org>
7642 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
7643 consider it a hit if to_charpos is anywhere in the range of the
7644 composed buffer positions.
7646 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
7648 * image.c (gif_load): Don't assume that each subimage has the same
7649 dimensions as the base image. Handle disposal method that is
7650 "undefined" by the gif spec (Bug#9335).
7652 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
7654 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
7655 (Fcondition_case): Document `debug' symbol in error handler.
7657 2011-08-19 Eli Zaretskii <eliz@gnu.org>
7659 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
7660 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
7661 from an Org mode buffer to a Speedbar frame.
7663 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
7664 a composition, take its buffer position from IT->cmp_it.charpos.
7665 Fixes cursor positioning at the beginning of a line that begins
7666 with a composed character.
7668 2011-08-18 Eli Zaretskii <eliz@gnu.org>
7670 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
7671 character bidirectional type, use STRONG_L instead. Fixes crashes
7672 in a buffer produced by `describe-categories'.
7674 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
7675 members before the level stack, so they would be saved and
7676 restored when copying iterator state. Fixes incorrect reordering
7677 around TABs covered by display properties.
7679 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
7681 * process.c (Fnetwork_interface_list): Correctly determine buffer size.
7683 2011-08-17 Chong Yidong <cyd@stupidchicken.com>

7686 (internal_condition_case_2, internal_condition_case_n):
7687 Remove unnecessary aborts (Bug#9081).
7689 2011-08-17 Eli Zaretskii <eliz@gnu.org>
7691 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
7692 has no `load' handler, try opening the file locally. (Bug#9311)
7694 2011-08-16 Ken Brown <kbrown@cornell.edu>
7696 * gmalloc.c: Expand comment.
7698 2011-08-16 Eli Zaretskii <eliz@gnu.org>
7700 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
7701 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.

7751 * xdisp.c (move_it_in_display_line_to): Don't invoke
7752 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
7753 ppos_it. Fixes vertical cursor motion when line beginning is
7754 covered by an image. (Bug#9296)
7756 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
7758 * nsterm.h (ns_run_ascript): Declare.

7762 (ns_run_ascript): New function.
7763 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
7764 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
7765 the event loop. Get status from as_status (Bug#7276).
7767 * nsterm.m (sendEvent): If event is NSApplicationDefined and
7768 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
7769 the event loop (Bug#7276).
7771 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
7773 * gnutls.c (QCgnutls_bootprop_priority)
7774 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
7775 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
7776 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)

7794 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
7795 (Fnetwork_interface_list): Allocate in increments of bytes instead
7796 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
7797 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
7798 sockaddr.
7799 (struct ifflag_def): notrailers is smart on OSX.
7800 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
7801 Get hardware address with getifaddrs if available.
7803 2011-08-12 Eli Zaretskii <eliz@gnu.org>
7805 * xdisp.c (iterate_out_of_display_property): xassert that
7806 IT->position is set to within IT->object's boundaries. Break from
7807 the loop as soon as EOB is reached; avoids infloops in redisplay
7808 when IT->position is set up wrongly due to some bug.
7809 Set IT->current to match the bidi iterator unconditionally.
7810 (push_display_prop): Allow GET_FROM_STRING as IT->method on
7811 entry. Force push_it to save on the stack the current
7812 buffer/string position, to be restored by pop_it. Fix flags in
7813 the iterator structure wrt the object coming from a display
7814 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
7815 properties. (Bug#9284)
7817 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
7819 * fontset.c (fontset_get_font_group): Add proper type checks.

7833 Set disp_pos in the bidi iterator to avoid searches for display
7834 properties and overlays.
7836 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
7838 * editfns.c (Fset_time_zone_rule): Document relationship with the

7844 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
7846 * composite.c (autocmp_chars): Don't reset point. That is done by
7847 restore_point_unwind (Bug#5984).
7849 2011-08-07 Juri Linkov <juri@jurta.org>
7851 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
7852 to show the arg `TIME' instead of `TIMEVAL'.
7854 2011-08-06 Eli Zaretskii <eliz@gnu.org>
7856 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
7857 display property strides EOL and includes a newline, as in
7858 longlines-mode. (Bug#9254)
7859 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
7860 word-wrap under bidirectional display. (Bug#9224)
7862 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
7863 is non-zero, even if the data buffer is NULL. Fixes a crash in
7864 vertical-motion with longlines-mode. (Bug#9254)
7866 2011-08-05 Eli Zaretskii <eliz@gnu.org>
7868 * bidi.c <bidi_cache_total_alloc>: Now static.
7869 (bidi_initialize): Initialize bidi_cache_total_alloc.
7871 * xdisp.c (display_line): Release buffer allocated for shelved bidi
7872 cache. (Bug#9221)
7874 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
7875 amount allocated this far in `bidi_cache_total_alloc'.
7876 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
7877 non-zero, only free the data buffer without restoring the cache
7878 contents. All callers changed.
7880 * dispextern.h (bidi_unshelve_cache): Update prototype.
7882 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
7883 (move_it_in_display_line, move_it_to)
7884 (move_it_vertically_backward, move_it_by_lines): Replace the call
7885 to xfree to an equivalent call to bidi_unshelve_cache.
7886 (move_it_in_display_line_to): Fix logic of returning
7887 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
7889 2011-08-05 Eli Zaretskii <eliz@gnu.org>
7891 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
7892 came from a string character with a `cursor' property. (Bug#9229)
7894 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
7896 * Makefile.in (LIB_PTHREAD): New variable.

7940 non-zero.
7942 * bidi.c (bidi_fetch_char): Accept an additional argument
7943 DISP_PROP_P, and pass it to compute_display_string_pos.
7944 Only handle text covered by a display string if DISP_PROP_P is returned
7945 non-zero. All callers of bidi_fetch_char changed.
7947 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>

7964 * xdisp.c (forward_to_next_line_start): Accept additional argument
7965 BIDI_IT_PREV, and store into it the state of the bidi iterator had
7966 on the newline.
7967 (reseat_at_next_visible_line_start): Use the bidi iterator state
7968 returned by forward_to_next_line_start to restore the state of
7969 it->bidi_it after backing up to previous newline. (Bug#9212)
7971 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>

7979 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
7980 This is needed if max-image-size is a floating-point number.
7982 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
7984 * print.c (print_object): Print empty symbol as ##.

8032 Without this fix, if a signal arrives just after memory fills up,
8033 'malloc' might be invoked reentrantly.
8035 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
8036 In other words, assume that every image size is allowed, on non-X
8037 hosts. This assumption is probably wrong, but it lets Emacs compile.
8039 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8041 * regex.c (re_iswctype): Convert return values to boolean.
8043 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
8045 * xdisp.c (compute_display_string_pos): Don't use cached display
8046 string position if the buffer had its restriction changed.
8047 (Bug#9184)
8049 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8051 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
8053 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8055 Integer signedness and overflow and related fixes. (Bug#9079)
8057 * bidi.c: Integer size and overflow fixes.
8058 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
8059 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
8060 (bidi_cache_find_level_change, bidi_cache_ensure_space)
8061 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
8062 (bidi_find_other_level_edge):
8063 Use ptrdiff_t instead of EMACS_INT where either will do.
8064 This works better on 32-bit hosts configured --with-wide-int.
8065 (bidi_cache_ensure_space): Check for size-calculation overflow.
8066 Use % rather than repeated addition, for better worst-case speed.
8067 Don't set bidi_cache_size until after xrealloc returns, because it
8068 might not return.
8069 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
8070 (bidi_cache_ensure_space): Also check that the bidi cache size
8071 does not exceed that of the largest Lisp string or buffer. See Eli
8072 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
8074 * alloc.c (__malloc_size_t): Remove.
8075 All uses replaced by size_t. See Andreas Schwab's note
8076 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
8078 * image.c: Improve checking for integer overflow.
8079 (check_image_size): Assume that f is nonnull, since
8080 it is always nonnull in practice. This is one less thing to
8081 worry about when checking for integer overflow later.
8082 (x_check_image_size): New function, which checks for integer
8083 overflow issues inside X.
8084 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
8085 This removes the need for a memory_full check.
8086 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
8087 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
8088 (xbm_read_bitmap_data): Change locals back to 'int', since
8089 their values must fit in 'int'.
8090 (xpm_load_image, png_load, tiff_load):
8091 Invoke x_create_x_image_and_pixmap earlier,
8092 to avoid much needless work if the image is too large.
8093 (tiff_load): Treat overly large images as if
8094 x_create_x_image_and_pixmap failed, not as malloc failures.
8095 (gs_load): Use x_check_image_size.
8097 * gtkutil.c: Omit integer casts.
8098 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
8099 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
8101 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
8103 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
8104 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
8105 would wrongly return t on a 64-bit host.
8107 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
8108 The plain *_OVERFLOW macros run afoul of GCC bug 49705
8109 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
8110 and therefore cause GCC to emit a bogus diagnostic in some cases.
8112 * image.c: Integer signedness and overflow and related fixes.
8113 This is not an exhaustive set of fixes, but it's time to
8114 record what I've got.
8115 (lookup_pixel_color, check_image_size): Remove redundant decls.
8116 (check_image_size): Don't assume that arbitrary EMACS_INT values
8117 fit in 'int', or that arbitrary 'double' values fit in 'int'.
8118 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
8119 (tiff_load, imagemagick_load_image):
8120 Check for overflow in size calculations.
8121 (x_create_x_image_and_pixmap): Remove unnecessary test for
8122 xmalloc returning NULL; that can't happen.
8123 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
8124 (xpm_color_bucket): Use better integer hashing function.
8125 (xpm_cache_color): Don't possibly over-allocate memory.
8126 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
8127 (gif_memory_source):
8128 Use ptrdiff_t, not int or size_t, to record sizes.
8129 (png_load): Don't assume values greater than 2**31 fit in 'int'.
8130 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
8131 either works, as we prefer signed integers.
8132 (tiff_read_from_memory, tiff_write_from_memory):
8133 Return tsize_t, not size_t, since that's what the TIFF API wants.
8134 (tiff_read_from_memory): Don't fail simply because the read would
8135 go past EOF; instead, return a short read.
8136 (tiff_load): Omit no-longer-needed casts.
8137 (Fimagemagick_types): Don't assume size fits into 'int'.
8139 Improve hashing quality when configured --with-wide-int.
8140 * fns.c (hash_string): New function, taken from sxhash_string.
8141 Do not discard information about ASCII character case; this
8142 discarding is no longer needed.
8143 (sxhash-string): Use it. Change sig to match it. Caller changed.
8144 * lisp.h: Declare it.
8145 * lread.c (hash_string): Remove, since we now use fns.c's version.
8146 The fns.c version returns a wider integer if --with-wide-int is
8147 specified, so this should help the quality of the hashing a bit.
8149 * emacs.c: Integer overflow minor fix.
8150 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
8151 Define only if GNU_LINUX.
8152 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
8154 * dispnew.c: Integer signedness and overflow fixes.
8155 Remove unnecessary forward decls, that were a maintenance hassle.
8156 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
8157 All uses changed.
8158 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
8159 (scrolling_window): Use ptrdiff_t, not int, for byte count.
8160 (prepare_desired_row, line_draw_cost):
8161 Use int, not unsigned, where either works.
8162 (save_current_matrix, restore_current_matrix):
8163 Use ptrdiff_t, not size_t, where either works.
8164 (init_display): Check for overflow more accurately, and without
8165 relying on undefined behavior.
8167 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
8168 Remove, replacing with the new symbols in lisp.h. All uses changed.
8169 * fileio.c (make_temp_name):
8170 * filelock.c (lock_file_1, lock_file):
8171 * xdisp.c (message_dolog):
8172 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
8173 Use pMd etc. instead.
8174 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
8175 replacing the pWIDE etc. symbols removed from editfns.c.
8177 * keyboard.h (num_input_events): Now uintmax_t.
8178 This is (very slightly) less likely to mess up due to wraparound.
8179 All uses changed.
8181 * buffer.c: Integer signedness fixes.
8182 (alloc_buffer_text, enlarge_buffer_text):
8183 Use ptrdiff_t rather than size_t when either will do, as we prefer
8184 signed integers.
8186 * alloc.c: Integer signedness and overflow fixes.
8187 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
8188 (__malloc_size_t): Default to size_t, not to int.
8189 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
8190 (Fgarbage_collect, mark_object_loop_halt, mark_object):
8191 Prefer ptrdiff_t to size_t when either would do, as we prefer
8192 signed integers.
8193 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
8194 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
8195 Now const. Initialize with values that are in range even if char
8196 is signed.
8197 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
8198 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
8199 These functions do the right thing with sizes > 2**32.
8200 (check_depth): Now ptrdiff_t, not int.
8201 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
8202 Adjust to new way of storing sizes. Check for size overflow bugs
8203 in rest of code.
8204 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
8205 slightly wrong anyway, as it missed one instance of
8206 XMALLOC_OVERRUN_CHECK_OVERHEAD.
8207 (refill_memory_reserve): Omit needless cast to size_t.
8208 (mark_object_loop_halt): Mark as externally visible.
8210 * xselect.c: Integer signedness and overflow fixes.
8211 (Fx_register_dnd_atom, x_handle_dnd_message):
8212 Use ptrdiff_t, not size_t, since we prefer signed.
8213 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
8214 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
8215 x_dnd_atoms_size and x_dnd_atoms_length.
8217 * doprnt.c: Prefer signed to unsigned when either works.
8218 * eval.c (verror):
8219 * doprnt.c (doprnt):
8220 * lisp.h (doprnt):
8221 * xdisp.c (vmessage):
8222 Use ptrdiff_t, not size_t, when using or implementing doprnt,
8223 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
8224 prefer signed arithmetic to avoid comparison confusion.
8225 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
8226 but is a bit tricky.
8228 Assume freestanding C89 headers, string.h, stdlib.h.
8229 * data.c, doprnt.c, floatfns.c, print.c:
8230 Include float.h unconditionally.
8231 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
8232 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
8233 * regex.c: Likewise for stddef.h, string.h.
8234 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
8235 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
8236 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
8237 (STDC_HEADERS): Remove obsolete defines.
8238 * sysdep.c: Include limits.h unconditionally.
8240 Assume support for memcmp, memcpy, memmove, memset.
8241 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
8242 * regex.c (memcmp, memcpy):
8243 Remove; we assume C89 now.
8245 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
8246 (__malloc_safe_bcopy): Remove; no longer needed.
8248 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
8249 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
8250 well either way, and we prefer signed to unsigned.
8252 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
8254 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
8255 closes the connection while we're reading (bug#9182).
8257 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
8259 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
8260 are specified (Bug#9168).
8262 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
8264 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
8265 Found by GCC static checking and --with-wide-int on a 32-bit host.
8267 2011-07-25 Eli Zaretskii <eliz@gnu.org>
8269 * xdisp.c (compute_display_string_pos): Fix logic of caching
8270 previous display string position. Initialize cached_prev_pos to
8271 -1. Fixes slow-down at the beginning of a buffer.
8273 2011-07-24 Eli Zaretskii <eliz@gnu.org>
8275 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
8276 for attrs[LFACE_FONTSET_INDEX].
8278 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
8280 * xml.c (parse_region): Remove unused local
8281 that was recently introduced.
8283 2011-07-23 Eli Zaretskii <eliz@gnu.org>
8285 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
8286 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
8288 * xdisp.c (move_it_in_display_line_to): Record the best matching
8289 position for TO_CHARPOS while scanning the line, and restore it on
8290 exit if none of the characters scanned was an exact match.
8291 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
8292 when exact match is impossible due to invisible text, and the
8293 lines are truncated.
8295 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
8297 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
8298 for OSX >= 10.7.
8300 2011-07-22 Eli Zaretskii <eliz@gnu.org>
8302 Fix a significant slow-down of cursor motion with C-n, C-p,
8303 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
8304 auto-repeat under bidi redisplay in fontified buffers.
8305 * xdisp.c (compute_stop_pos_backwards): New function.
8306 (next_element_from_buffer): Call compute_stop_pos_backwards to
8307 find a suitable prev_stop when we find ourselves before
8308 base_level_stop.
8309 (reseat): Don't look for prev_stop, as that could mean a very long
8310 run.
8311 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
8312 <cached_disp_overlay_modiff>: Cache for last found display string
8313 position.
8314 (compute_display_string_pos): Return the cached position if asked
8315 about the same buffer in the same area of character positions, and
8316 the buffer wasn't changed since the time the display string
8317 position was cached.
8319 2011-07-22 Eli Zaretskii <eliz@gnu.org>
8321 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
8322 is an integer, which is important for empty lines. (Bug#9149)
8324 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
8326 * frame.c (Fmodify_frame_parameters): In tty case, update the
8327 default face if necessary (Bug#4238).
8329 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
8331 * editfns.c (Fstring_to_char): No need to explain what a character
8332 is in the docstring (Bug#6576).
8334 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
8336 * xml.c (parse_region): Make sure we always return a tree.
8338 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
8340 * xml.c (parse_region): If a document contains only comments,
8341 return that, too.
8343 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
8345 * xml.c (make_dom): Return comments, too.
8347 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
8349 Port to OpenBSD.
8350 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
8351 and the surrounding thread.
8352 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
8353 rather than fgets, and retry after EINTR. Otherwise, 'emacs
8354 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
8355 timer goes off.
8356 * s/openbsd.h (BROKEN_SIGIO): Define.
8357 * unexelf.c (unexec) [__OpenBSD__]:
8358 Don't update the .mdebug section of the Alpha COFF symbol table.
8360 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
8362 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
8363 (bug#8460).
8365 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
8367 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
8368 This fixes some race conditions on the permissions of any newly
8369 created file.
8371 * alloc.c (valid_pointer_p): Use pipe, not open.
8372 This fixes some permissions issues when debugging.
8374 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
8375 If fchown fails to set both uid and gid, try to set just gid,
8376 as that is sometimes allowed. Adjust the file's mode to eliminate
8377 setuid or setgid bits that are inappropriate if fchown fails.
8379 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
8381 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
8382 to compare Lisp_Objects.
8383 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
8384 global_gnutls_log_level, don't mistake it for a Lisp_Object.
8385 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
8387 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
8389 * lread.c (read_integer): Unread even EOF character.
8390 (read1): Likewise. Properly record start position of symbol.
8392 * lread.c (read1): Read `#:' as empty uninterned symbol if no
8393 symbol character follows.
8395 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
8397 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
8398 This works around a problem with the previous change to Fcopy_file.
8399 Recent glibc declares fchown with __attribute__((warn_unused_result)),
8400 and without this change, GCC might complain about discarding
8401 fchown's return value.
8403 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
8405 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
8407 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
8409 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
8411 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
8413 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
8414 it's used from the C level.
8416 * process.c: Use the same condition for POLL_FOR_INPUT in both
8417 keyboard.c and process.c (bug#1858).
8419 2011-07-09 Lawrence Mitchell <wence@gmx.li>
8421 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
8422 (Fgnutls_boot): Use it.
8424 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
8426 * doc.c (Fsubstitute_command_keys): Revert last change.
8428 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
8430 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
8431 quotes the next character, and doesn't affect other longer
8432 sequences (bug#8935).
8434 * lread.c (syms_of_lread): Clarify that is isn't only
8435 `eval-buffer' and `eval-defun' that's affected by
8436 `lexical-binding' (bug#8460).
8438 2011-07-15 Eli Zaretskii <eliz@gnu.org>
8440 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
8441 bidi redisplay when a line includes both an image and is truncated.
8443 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
8445 Fix minor problems found by static checking.
8446 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
8447 (elsz): Now a signed constant, not a size_t var. We prefer signed
8448 types to unsigned, to avoid integer comparison confusion. Without
8449 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
8450 "cannot optimize loop, the loop counter may overflow", a symptom
8451 of the confusion.
8452 * indent.c (Fvertical_motion): Mark locals as initialized.
8453 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
8455 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
8457 * search.c (Fre_search_backward): Mention `case-fold-search' in
8458 all the re_search_* functions (bug#8138).
8460 * keyboard.c (Fopen_dribble_file): Document when the file is
8461 closed (bug#8056).
8463 2011-07-14 Eli Zaretskii <eliz@gnu.org>
8465 * bidi.c (bidi_dump_cached_states): Fix format of displaying
8466 bidi_cache_idx.
8468 Support bidi reordering of display and overlay strings.
8469 * xdisp.c (compute_display_string_pos)
8470 (compute_display_string_end): Accept additional argument STRING.
8471 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
8472 (reseat_to_string): Initialize bidi_it->string.s and
8473 bidi_it->string.schars.
8474 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
8475 NULL (avoids a crash in bidi_paragraph_init).
8476 Initialize itb.string.lstring.
8477 (init_iterator): Call bidi_init_it only of a valid
8478 buffer position was specified. Initialize paragraph_embedding to
8479 L2R.
8480 (reseat_to_string): Initialize the bidi iterator.
8481 (display_string): If we need to ignore text properties of

8977 (clone_per_buffer_values): Don't assume that

8979 This isn't true in general, and it's particularly not true
8980 if Emacs is configured with --with-wide-int.
8981 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):

9016 2011-07-05 Paul Eggert <eggert@cs.ucla.edu>
9018 Random fixes. E.g., (random) never returned negative values.
9019 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
9020 subseconds part to the entropy, as that's a bit more random.
9021 Prefer signed to unsigned, since the signedness doesn't matter and
9022 in general we prefer signed. When given a limit, use a
9023 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
9024 latter isn't right if USE_2_TAGS_FOR_INTS.
9025 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
9026 not 0..VALMASK. Don't discard "excess" bits that random () returns.
9028 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
9030 * textprop.c (text_property_stickiness):
9031 Obey Vtext_property_default_nonsticky.

9039 This is more efficient than Ffile_directory_p and avoids a minor race.
9041 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
9043 * buffer.c (Foverlay_put): Say what the return value is
9044 (bug#7835).
9046 * fileio.c (barf_or_query_if_file_exists): Check first if the file
9047 is a directory before asking whether to use the file name
9048 (bug#7564).
9049 (barf_or_query_if_file_exists): Make the "File is a directory"
9050 error be more correct.
9052 * fns.c (Frequire): Remove the mention of the .gz files, since
9053 that's installation-specific, but keep the mention of
9054 `get-load-suffixes'.
9056 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
9058 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

9068 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
9069 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
9070 Also (re)move comments that are misplaced or no longer relevant.
9072 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
9074 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

9133 (syms_of_keymap): Defsubr make-composed-keymap.
9134 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

9171 * eval.c (struct backtrace): Simplify and port the data structure.
9172 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
9173 signed bit field, as this assumption is not portable and it makes
9174 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
9175 "char debug_on_exit : 1" as this is not portable either; instead,
9176 use the portable "unsigned int debug_on_exit : 1". Remove unused
9177 member evalargs. Remove obsolete comments about cc bombing out.
9179 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

9367 (read1): Check for integer overflow in radices, and in
9368 read-circle numbers.
9369 (read_escape): Avoid int overflow.
9370 (Fload, openp, read_buffer_size, read1)
9371 (substitute_object_recurse, read_vector, read_list, map_obarray):
9372 Use ptrdiff_t, not int, for sizes.
9373 (read1): Use EMACS_INT, not int, for sizes.
9374 Check for size overflow.
9376 * image.c (cache_image): Check for size arithmetic overflow.
9378 * lread.c: Integer overflow issues.
9379 (saved_doc_string_size, saved_doc_string_length)
9380 (prev_saved_doc_string_size, prev_saved_doc_string_length):
9381 Now ptrdiff_t, not int.
9382 (read1): Don't assume doc string length fits in int. Check for
9383 out-of-range doc string lengths.
9384 (read_list): Don't assume file position fits in int.
9385 (read_escape): Check for hex character overflow.
9387 2011-06-22 Leo Liu <sdl.web@gmail.com>
9389 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
9390 Move to minibuffer.el.
9392 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
9394 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
9395 The following patches are for when GLYPH_DEBUG && !XASSERT.
9396 * dispextern.h (trace_redisplay_p, dump_glyph_string):
9397 * dispnew.c (flush_stdout):
9398 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
9399 Mark as externally visible.
9400 * dispnew.c (check_window_matrix_pointers): Now static.
9401 * dispnew.c (window_to_frame_vpos):
9402 * xfns.c (unwind_create_frame):
9403 * xterm.c (x_check_font): Remove unused local.
9404 * scroll.c (CHECK_BOUNDS):
9405 * xfaces.c (cache_fache): Rename local to avoid shadowing.
9406 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
9407 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
9408 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
9409 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
9410 Now static.
9411 (debug_method_add): Use va_list and vsprintf rather than relying
9412 on undefined behavior with wrong number of arguments.
9413 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
9414 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
9415 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
9416 since we're not interested in debugging glyphs with old libraries.
9417 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
9418 GCC 4.6.0's static checking.
9420 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
9422 Integer overflow and signedness fixes (Bug#8873).

9429 (x_bitmap_mask, x_allocate_bitmap_record)
9430 (x_create_bitmap_from_data, x_create_bitmap_from_file)
9431 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
9432 (x_create_bitmap_from_xpm_data):
9433 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
9434 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
9435 (.bitmaps_last):
9436 * xfaces.c (load_pixmap):
9437 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
9438 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
9439 (.bitmaps_last, struct x_output.icon_bitmap):
9440 Use ptrdiff_t, not int, for bitmap indexes.
9441 (x_allocate_bitmap_record): Check for size overflow.
9442 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
9444 Use ptrdiff_t, not int, for overlay counts.
9445 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
9446 * editfns.c (overlays_around, get_pos_property):
9447 * textprop.c (get_char_property_and_overlay):
9448 * xdisp.c (next_overlay_change, note_mouse_highlight):
9449 * xfaces.c (face_at_buffer_position):
9450 * buffer.c (OVERLAY_COUNT_MAX): New macro.
9451 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
9452 (Fnext_overlay_change, Fprevious_overlay_change)
9453 (mouse_face_overlay_overlaps, Foverlays_in):
9454 Use ptrdiff_t, not int, for sizes.
9455 (overlays_at, overlays_in): Check for size-calculation overflow.
9457 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
9459 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
9460 (x_session_initialize): Do not assume string length fits in int.
9462 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
9463 This is unlikely, but can occur if DPI is outlandish.
9465 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
9466 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
9468 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
9469 * xrdb.c (magic_file_p, search_magic_path):
9470 Omit last arg SUFFIX; it was always 0. All callers changed.
9471 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
9473 * xfont.c (xfont_match): Avoid need for strlen.
9475 * xfns.c: Don't assume strlen fits in int.
9476 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
9478 * xdisp.c (message_log_check_duplicate): Return intmax_t,
9479 not unsigned long, as we prefer signed integers. All callers changed.
9480 Detect integer overflow in repeat count.
9481 (message_dolog): Don't assume print length fits in 39 bytes.
9482 (display_mode_element): Don't assume strlen fits in int.
9484 * termcap.c: Don't assume sizes fit in int and never overflow.
9485 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
9486 (gobble_line): Check for size-calculation overflow.
9488 * minibuf.c (Fread_buffer):
9489 * lread.c (intern, intern_c_string):
9490 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
9491 Don't assume string length fits in int.
9493 * keyboard.c (parse_tool_bar_item):
9494 * gtkutil.c (style_changed_cb): Avoid need for strlen.
9496 * font.c: Don't assume string length fits in int.
9497 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
9498 Use ptrdiff_t, not int.
9499 (font_intern_prop): Don't assume string length fits in int.
9500 Don't assume integer property fits in fixnum.
9501 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
9503 * filelock.c: Fix some buffer overrun and integer overflow issues.
9504 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
9505 Reformulate so as not to need the command string.
9506 Invoke gzip -cd rather than gunzip, as it's more portable.
9507 (lock_info_type, lock_file_1, lock_file):
9508 Don't assume pid_t and time_t fit in unsigned long.
9509 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
9510 (current_lock_owner): Prefer signed type for sizes.
9511 Use memcpy, not strncpy, where memcpy is what is really wanted.
9512 Don't assume (via atoi) that time_t and pid_t fit in int.
9513 Check for time_t and/or pid_t out of range, e.g., via a network share.
9514 Don't alloca where an auto var works fine.
9516 * fileio.c: Fix some integer overflow issues.
9517 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
9518 Don't assume string length fits in int.
9519 (directory_file_name): Don't assume string length fits in long.
9520 (make_temp_name): Don't assume pid fits in int, or that its print
9521 length is less than 20.
9523 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
9525 * coding.c (make_subsidiaries): Don't assume string length fits in int.
9527 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
9529 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
9530 We prefer signed integers, even for size calculations.
9532 * emacs.c: Don't assume string length fits in 'int'.
9533 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
9534 (main): Don't invoke strlen when not needed.
9536 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
9537 (XD_DEBUG_MESSAGE): Don't waste a byte.
9539 * callproc.c (getenv_internal_1, getenv_internal)
9540 (Fgetenv_internal):
9541 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
9543 * lread.c (invalid_syntax): Omit length argument.
9544 All uses changed. This doesn't fix a bug, but it simplifies the
9545 code away from its former Hollerith-constant appearance, and it's
9546 one less 'int' to worry about when looking at integer-overflow issues.
9547 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
9549 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
9550 This didn't break anything, but it didn't help either.
9551 It's confusing to put a bogus integer in a place where the actual
9552 value does not matter.
9553 (LIST_END_P): Remove unused macro and its bogus comment.
9554 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
9556 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
9557 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
9558 implementation.
9559 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
9560 We prefer signed types, and the value cannot exceed the EMACS_INT
9561 range anyway (because otherwise the length would not be representable).
9562 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
9563 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
9564 This avoids a GCC warning when WIDE_EMACS_INT.
9566 * indent.c (sane_tab_width): New function.
9567 (current_column, scan_for_column, Findent_to, position_indentation)
9568 (compute_motion): Use it. This is just for clarity.
9569 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
9571 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
9573 * lisp.h (lint_assume): New macro.
9574 * composite.c (composition_gstring_put_cache):
9575 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
9577 * editfns.c, insdel.c:
9578 Omit unnecessary forward decls, to simplify future changes.
9580 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
9582 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
9584 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
9585 Use much-faster test for byte-length change.
9586 Don't assume string byte-length fits in 'int'.
9587 Check that character arg fits in 'int'.
9588 (mapcar1): Declare byte as byte, for clarity.
9590 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
9592 * fns.c (concat): Catch string overflow earlier.
9593 Do not rely on integer wraparound.
9595 * dispextern.h (struct it.overlay_strings_charpos)
9596 (struct it.selective): Now EMACS_INT, not int.
9597 * xdisp.c (forward_to_next_line_start)
9598 (back_to_previous_visible_line_start)
9599 (reseat_at_next_visible_line_start, next_element_from_buffer):
9600 Don't arbitrarily truncate the value of 'selective' to int.
9602 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
9604 * composite.c: Don't truncate sizes to 'int'.
9605 (composition_gstring_p, composition_reseat_it)
9606 (composition_adjust_point): Use EMACS_INT, not int.
9607 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
9608 not EMACS_UINT, for indexes.
9610 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
9612 * buffer.c: Include <verify.h>.
9613 (struct sortvec.priority, struct sortstr.priority):
9614 Now EMACS_INT, not int.
9615 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
9616 (struct sortstr.size, record_overlay_string)
9617 (struct sortstrlist.size, struct sortlist.used):
9618 Don't truncate size to int.
9619 (record_overlay_string): Check for size-calculation overflow.
9620 (init_buffer_once): Check at compile-time, not run-time.
9622 2011-06-22 Jim Meyering <meyering@redhat.com>
9624 Don't leak an XBM-image-sized buffer
9625 * image.c (xbm_load): Free the image buffer after using it.
9627 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
9629 Port to Sun C.
9630 * composite.c (find_automatic_composition): Omit needless 'return 0;'
9631 that Sun C diagnosed.
9632 * fns.c (secure_hash): Fix pointer signedness issue.
9633 * intervals.c (static_offset_intervals): New function.
9634 (offset_intervals): Use it.
9636 2011-06-21 Leo Liu <sdl.web@gmail.com>
9638 * deps.mk (fns.o):
9639 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
9640 sha512.h.
9642 * fns.c (secure_hash): Rename from crypto_hash_function and change
9643 the first arg to accept symbols.
9644 (Fsecure_hash): New primitive.
9645 (syms_of_fns): New symbols.
9647 2011-06-20 Deniz Dogan <deniz@dogan.se>
9649 * process.c (Fset_process_buffer): Clarify return value in
9650 docstring.
9652 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
9654 * dispnew.c (add_window_display_history): Use BVAR.
9656 * xdisp.c (debug_method_add): Use BVAR.
9657 (check_window_end, dump_glyph_matrix, dump_glyph)
9658 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
9660 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
9661 Likewise.
9663 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
9664 check till after the cache is created in init_frame_faces.
9666 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
9668 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
9670 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
9672 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
9673 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
9674 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
9676 Improve buffer-overflow checking (Bug#8873).
9677 * fileio.c (Finsert_file_contents):
9678 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
9679 Remove the old (too-loose) buffer overflow checks.
9680 They weren't needed, since make_gap checks for buffer overflow.
9681 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
9682 The old code merely checked for Emacs fixnum overflow, and relied
9683 on undefined (wraparound) behavior. The new code avoids undefined
9684 behavior, and also checks for ptrdiff_t and/or size_t overflow.
9686 * editfns.c (Finsert_char): Don't dump core with very negative counts.
9687 Tune. Don't use wider integers than needed. Don't use alloca.
9688 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
9690 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
9692 * insdel.c, lisp.h (buffer_overflow): New function.
9693 (insert_from_buffer_1, replace_range, replace_range_2):
9694 * insdel.c (make_gap_larger):
9695 * editfns.c (Finsert_char):
9696 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
9698 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
9700 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
9702 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
9704 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
9705 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
9707 * fileio.c: Don't assume EMACS_INT fits in off_t.
9708 (emacs_lseek): New static function.
9709 (Finsert_file_contents, Fwrite_region): Use it.
9710 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
9712 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
9714 * fns.c: Don't overflow int when computing a list length.
9715 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
9716 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
9717 truncation on 64-bit hosts. Check for QUIT every
9718 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
9719 faster and is responsive enough.
9720 (Flength): Report an error instead of overflowing an integer.
9721 (Fsafe_length): Return a float if the value is not representable
9722 as a fixnum. This shouldn't happen except in contrived situations.
9723 (Fnthcdr, Fsort): Don't assume list length fits in int.
9724 (Fcopy_sequence): Don't assume vector length fits in int.
9726 * alloc.c: Check that resized vectors' lengths fit in fixnums.
9727 (header_size, word_size): New constants.
9728 (allocate_vectorlike): Don't check size overflow here.
9729 (allocate_vector): Check it here instead, since this is the only
9730 caller of allocate_vectorlike that could cause overflow.
9731 Check that the new vector's length is representable as a fixnum.
9733 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
9734 The previous code was bogus. For example, next_almost_prime (32)
9735 returned 39, which is undesirable as it is a multiple of 3; and
9736 next_almost_prime (24) returned 25, which is a multiple of 5 so
9737 why was the code bothering to check for multiples of 7?
9739 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
9741 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
9743 Variadic C functions now count arguments with ptrdiff_t.
9744 This partly undoes my 2011-03-30 change, which replaced int with size_t.
9745 Back then I didn't know that the Emacs coding style prefers signed int.
9746 Also, in the meantime I found a few more instances where arguments
9747 were being counted with int, which may truncate counts on 64-bit
9748 machines, or EMACS_INT, which may be unnecessarily wide.
9749 * lisp.h (struct Lisp_Subr.function.aMANY)
9750 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
9751 Arg counts are now ptrdiff_t, not size_t.
9752 All variadic functions and their callers changed accordingly.
9753 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
9754 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
9755 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
9756 * callint.c (Fcall_interactively): Check arg count for overflow,
9757 to avoid potential buffer overrun. Use signed char, not 'int',
9758 for 'varies' array, so that we needn't bother to check its size
9759 calculation for overflow.
9760 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
9761 * eval.c (apply_lambda):
9762 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
9763 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
9764 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
9766 * callint.c (Fcall_interactively): Don't use index var as event count.
9768 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
9769 * mem-limits.h (SIZE): Remove; no longer used.
9771 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
9773 Remove unnecessary casts.
9774 * xterm.c (x_term_init):
9775 * xfns.c (x_set_border_pixel):
9776 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
9777 These aren't needed now that we assume ANSI C.
9779 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
9780 It's more likely to cause problems (due to unsigned overflow)
9781 than to cure them.
9783 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
9785 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
9787 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
9789 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
9791 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
9793 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
9795 GLYPH_CODE_FACE returns EMACS_INT, not int.
9796 * dispextern.h (merge_faces):
9797 * xfaces.c (merge_faces):
9798 * xdisp.c (get_next_display_element, next_element_from_display_vector):
9799 Don't assume EMACS_INT fits in int.
9801 * character.h (CHAR_VALID_P): Remove unused parameter.
9802 * fontset.c, lisp.h, xdisp.c: All uses changed.
9804 * editfns.c (Ftranslate_region_internal): Omit redundant test.
9806 * fns.c (concat): Minor tuning based on overflow analysis.
9807 This doesn't fix any bugs. Use int to hold character, instead
9808 of constantly refetching from Emacs object. Use XFASTINT, not
9809 XINT, for value known to be a character. Don't bother comparing
9810 a single byte to 0400, as it's always less.
9812 * floatfns.c (Fexpt):
9813 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
9815 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
9816 for characters.
9818 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
9820 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
9821 Without this fix, on a 64-bit host (aset S 0 4294967386) would
9822 incorrectly succeed when S was a string, because 4294967386 was
9823 truncated before it was used.
9825 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
9826 Otherwise, an out-of-range integer could cause undefined behavior
9827 on a 64-bit host.
9829 * composite.c: Use int, not EMACS_INT, for characters.
9830 (fill_gstring_body, composition_compute_stop_pos): Use int, not
9831 EMACS_INT, for values that are known to be in character range.
9832 This doesn't fix any bugs but is the usual style inside Emacs and
9833 may generate better code on 32-bit machines.
9835 Make sure a 64-bit char is never passed to ENCODE_CHAR.
9836 This is for reasons similar to the recent CHAR_STRING fix.
9837 * charset.c (Fencode_char): Check that character arg is actually
9838 a character. Pass an int to ENCODE_CHAR.
9839 * charset.h (ENCODE_CHAR): Verify that the character argument is no
9840 wider than 'int', as a compile-time check to prevent future regressions
9841 in this area.
9843 * character.c (char_string): Remove unnecessary casts.
9845 Make sure a 64-bit char is never passed to CHAR_STRING.
9846 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
9847 by silently ignoring the top 32 bits, allowing some values
9848 that were far too large to be valid characters.
9849 * character.h: Include <verify.h>.
9850 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
9851 arguments are no wider than unsigned, as a compile-time check
9852 to prevent future regressions in this area.
9853 * data.c (Faset):
9854 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
9855 (Fsubst_char_in_region):
9856 * fns.c (concat):
9857 * xdisp.c (decode_mode_spec_coding):
9858 Adjust to CHAR_STRING's new requirement.
9859 * editfns.c (Finsert_char, Fsubst_char_in_region):
9860 * fns.c (concat): Check that character args are actually
9861 characters. Without this test, these functions did the wrong
9862 thing with wildly out-of-range values on 64-bit hosts.
9864 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
9865 These casts should not be needed on 32-bit hosts, either.
9866 * keyboard.c (read_char):
9867 * lread.c (Fload): Remove casts to unsigned.
9869 * lisp.h (UNSIGNED_CMP): New macro.
9870 This fixes comparison bugs on 64-bit hosts.
9871 (ASCII_CHAR_P): Use it.
9872 * casefiddle.c (casify_object):
9873 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
9874 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
9875 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
9876 * dispextern.h (FACE_FROM_ID):
9877 * keyboard.c (read_char): Use UNSIGNED_CMP.
9879 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
9880 not to EMACS_INT, to avoid GCC warning.
9882 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
9884 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
9885 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
9886 isn't needed on 32-bit machines.
9888 * buffer.c (Fgenerate_new_buffer_name):
9889 Use EMACS_INT for count, not int.
9890 (advance_to_char_boundary): Return EMACS_INT, not int.
9892 * data.c (Qcompiled_function): Now static.
9894 * window.c (window_body_lines): Now static.
9896 * image.c (gif_load): Rename local to avoid shadowing.
9898 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
9899 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
9900 * alloc.c (make_save_value): Integer argument is now of type
9901 ptrdiff_t, not int.
9902 (mark_object): Use ptrdiff_t, not int.
9903 * lisp.h (pD): New macro.
9904 * print.c (print_object): Use it.
9906 * alloc.c: Use EMACS_INT, not int, to count objects.
9907 (total_conses, total_markers, total_symbols, total_vector_size)
9908 (total_free_conses, total_free_markers, total_free_symbols)
9909 (total_free_floats, total_floats, total_free_intervals)
9910 (total_intervals, total_strings, total_free_strings):
9911 Now EMACS_INT, not int. All uses changed.
9912 (Fgarbage_collect): Compute overall total using a double, so that
9913 integer overflow is less likely to be a problem. Check for overflow
9914 when converting back to an integer.
9915 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
9916 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
9917 These were 'int' variables that could overflow on 64-bit hosts;
9918 they were never used, so remove them instead of repairing them.
9919 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
9920 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
9921 Previously, this ceilinged at INT_MAX, but that doesn't work on
9922 64-bit machines.
9923 (allocate_pseudovector): Don't use EMACS_INT when int would do.
9925 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
9926 (allocate_vectorlike): Check for ptrdiff_t overflow.
9927 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
9928 when a (possibly-narrower) signed value would do just as well.
9929 We prefer using signed arithmetic, to avoid comparison confusion.
9931 * alloc.c: Catch some string size overflows that we were missing.
9932 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
9933 for convenience in STRING_BYTES_MAX.
9934 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
9935 The definition here is exact; the one in lisp.h was approximate.
9936 (allocate_string_data): Check for string overflow. This catches
9937 some instances we weren't catching before. Also, it catches
9938 size_t overflow on (unusual) hosts where SIZE_MAX <= min
9939 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
9940 and ptrdiff_t and EMACS_INT are both 64 bits.
9942 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
9943 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
9944 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
9946 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
9948 * alloc.c (Fmake_string): Check for out-of-range init.
9950 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
9952 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
9954 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
9956 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
9957 xg_get_default_scrollbar_width.
9959 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.

9965 Call gtk_window_set_resizable if HAVE_GTK3.
9966 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
9967 and height if HAVE_GTK3 (Bug#8505).
9968 (scroll_bar_width_for_theme): New variable.
9969 (update_theme_scrollbar_width): New function.
9970 (xg_get_default_scrollbar_width): Move code to
9971 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.

9974 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
9976 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
9978 2011-06-12 Martin Rudalics <rudalics@gmx.at>

9981 other_buffer.
9983 * window.c (temp_output_buffer_show): Call display_buffer with
9984 second argument Vtemp_buffer_show_specifiers and reset latter
9985 immediately after the call.
9986 (Vtemp_buffer_show_specifiers): New variable.
9987 (auto_window_vscroll_p, next_screen_context_lines)
9988 (Vscroll_preserve_screen_position): Remove leading asterisks from
9989 doc-strings.
9991 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>

10449 Do not assume that spare memory exists; that assumption is valid
10450 only if SYSTEM_MALLOC.
10451 (LARGE_REQUEST): New macro, so that the issue of large requests
10452 is separated from the issue of spare memory.

10521 instead of using explicit *_CHAR codes.
10522 (bidi_resolve_explicit, bidi_resolve_weak):
10523 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
10524 bidirectional text is supported only in multibyte buffers.

10533 were just reseat()'ed to a new position.
10535 * xdisp.c (set_cursor_from_row): Set start and stop points
10536 according to the row's direction when priming the loop that looks

10539 (display_prop_intangible_p): Reimplement to call
10540 handle_display_spec instead of single_display_spec_intangible_p.
10541 Accept 3 additional arguments needed by handle_display_spec.
10542 This fixes incorrect cursor motion across display property with complex
10543 values: lists, `(when COND...)' forms, etc.

10552 value of a `display' property is a "replacing spec".
10553 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
10554 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from

10582 All callers changed. (Bug#8762)
10584 * gnutls.c: Use Emacs's memory allocators.
10585 Without this change, the gnutls library would invoke malloc etc.
10586 directly, which causes problems on non-SYNC_INPUT hosts, and which
10587 runs afoul of improving memory_full behavior. (Bug#8761)
10588 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
10589 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
10590 xfree instead of the default malloc, realloc, free.
10591 (Fgnutls_boot): No need to check for memory allocation failure,
10592 since xmalloc does that for us.
10594 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)

10618 * ccl.c (ccl_driver):
10619 Check for overflow when converting EMACS_INT to int.
10620 * fns.c, image.c: Remove unnecessary static decls that would otherwise
10621 need to be updated by these changes.
10622 * fns.c (make_hash_table, maybe_resize_hash_table):
10623 Check for integer overflow with large hash tables.
10624 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
10625 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
10626 (SXHASH_REDUCE): New macro.
10627 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
10628 Use it instead of discarding useful hash info with large hash values.
10629 (sxhash_float): New function.
10630 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
10631 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
10632 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
10633 Rewrite to use FIXNUM_BITS, as this simplifies things.
10634 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
10635 Adjust signatures to match updated version of code.
10636 (consing_since_gc): Now EMACS_INT, since a single hash table can
10637 use more than INT_MAX bytes.

10664 * frame.c (make_initial_frame): Initialize faces in all cases, not
10665 only when CANNOT_DUMP is defined.
10666 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
10668 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
10670 * dispnew.c (add_window_display_history): Use const for the string
10671 pointer. Remove declaration, not needed.
10673 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
10675 Use 'inline', not 'INLINE'.
10676 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
10677 * alloc.c, fontset.c (INLINE): Remove.
10678 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
10679 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
10680 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
10681 * gmalloc.c (register_heapinfo): Use inline unconditionally.
10682 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
10684 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
10686 Make it possible to run ./temacs.
10688 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
10689 syms_of_callproc does the same thing. Remove test for
10690 "initialized", do it in the caller.
10691 * emacs.c (main): Avoid calling set_initial_environment when dumping.
10693 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
10695 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
10696 (read_minibuf): Use get_minibuffer.
10697 (syms_of_minibuf): Use DEFSYM.
10698 (Qmetadata): New var.
10699 * data.c (Qbuffer): Don't make it static.
10700 (syms_of_data): Use DEFSYM.
10702 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
10704 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
10705 (CCL_CODE_MIN): New macro.
10707 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
10709 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
10711 * eval.c (Qdebug): Now static.
10712 * lisp.h (Qdebug): Remove decl. This reverts a part of the
10713 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
10714 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
10716 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
10718 * image.c: Various fixes to ImageMagick code comments.
10719 (Fimagemagick_types): Doc fix.
10721 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
10723 Minor fixes prompted by GCC 4.6.0 warnings.
10725 * xselect.c (converted_selections, conversion_fail_tag): Now static.
10727 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
10728 (x_clipboard_manager_save_all): Move extern decl to ...
10729 * xterm.h: ... here, so that it can be checked for consistency.
10731 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
10733 * xselect.c (x_clipboard_manager_save_frame)
10734 (x_clipboard_manager_save_all): New functions.
10735 (Fx_clipboard_manager_save): Lisp function deleted.
10737 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
10738 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
10740 * xterm.h: Update prototype.
10742 2011-05-28 William Xu <william.xwl@gmail.com>
10744 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
10745 exiting (Bug#8239).
10747 2011-05-28 Jim Meyering <meyering@redhat.com>
10749 Avoid a sign-extension bug in crypto_hash_function.
10750 * fns.c (to_uchar): Define.
10751 (crypto_hash_function): Use it to convert some newly-signed
10752 variables to unsigned, to avoid sign-extension bugs. For example,
10753 without this change, (md5 "truc") would evaluate to
10754 45723a2aff78ff4fff7fff1114760e62 rather than the expected
10755 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
10756 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
10758 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
10760 Integer overflow fixes.
10762 * dbusbind.c: Serial number integer overflow fixes.
10763 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
10764 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
10765 to hold a serial number that is too large for a fixnum.
10766 (Fdbus_method_return_internal, Fdbus_method_error_internal):
10767 Check for serial numbers out of range. Decode any serial number
10768 that was so large that it became a float. (Bug#8722)
10770 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
10771 (Fdbus_call_method, Fdbus_call_method_asynchronously):
10772 Use XFASTINT rather than XUINT when numbers are nonnegative.
10773 (xd_append_arg, Fdbus_method_return_internal):
10774 (Fdbus_method_error_internal): Likewise. Also, for unsigned
10775 arguments, check that Lisp number is nonnegative, rather than
10776 silently wrapping negative numbers around. (Bug#8722)
10777 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
10778 (Bug#8722)
10780 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
10782 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
10784 ccl: Add integer overflow checks.
10785 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
10786 (IN_INT_RANGE): New macros.
10787 (ccl_driver): Use them to check for integer overflow when
10788 decoding a CCL program. Many of the new checks are whether XINT (x)
10789 fits in int; it doesn't always, on 64-bit hosts. The new version
10790 doesn't catch all possible integer overflows, but it's an
10791 improvement. (Bug#8719)
10793 * alloc.c (make_event_array): Use XINT, not XUINT.
10794 There's no need for unsigned here.
10796 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
10797 This follows up to the 2011-05-06 change that substituted uintptr_t
10798 for EMACS_INT. This case wasn't caught back then.
10800 Rework Fformat to avoid integer overflow issues.
10801 * editfns.c: Include <float.h> unconditionally, as it's everywhere
10802 now (part of C89). Include <verify.h>.
10803 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
10804 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
10805 (Fformat): Avoid the prepass trying to compute sizes; it was only
10806 approximate and thus did not catch overflow reliably. Instead, walk
10807 through the format just once, formatting and computing sizes as we go,
10808 checking for integer overflow at every step, and allocating a larger
10809 buffer as needed. Keep track separately whether the format is
10810 multibyte. Keep only the most-recently calculated precision, rather
10811 than them all. Record whether each argument has been converted to
10812 string. Use EMACS_INT, not int, for byte and char and arg counts.
10813 Support field widths and precisions larger than INT_MAX. Avoid
10814 sprintf's undefined behavior with conversion specifications such as %#d
10815 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
10816 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
10817 formatting out-of-range floating point numbers with int
10818 formats. (Bug#8668)
10820 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
10822 * data.c: Avoid integer truncation in expressions involving floats.
10823 * data.c: Include <intprops.h>.
10824 (arith_driver): When there's an integer overflow in an expression
10825 involving floating point, convert the integers to floating point
10826 so that the resulting value does not suffer from catastrophic
10827 integer truncation. For example, on a 64-bit host (* 4
10828 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
10829 Do not rely on undefined behavior after integer overflow.
10831 merge count_size_as_multibyte, parse_str_to_multibyte
10832 * character.c, character.h (count_size_as_multibyte):
10833 Rename from parse_str_to_multibyte; all uses changed.
10834 Check for integer overflow.
10835 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
10836 since it's now a duplicate of the other. This is more of
10837 a character than a buffer op, so better that it's in character.c.
10838 * fns.c, print.c: Adjust to above changes.
10840 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
10842 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
10844 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
10846 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
10847 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
10848 (x_clipboard_manager_save): Now static.
10849 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
10851 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
10852 (crypto_hash_function): Now static.
10853 Fix pointer signedness problems. Avoid unnecessary initializations.
10855 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
10857 * termhooks.h (Vselection_alist): Make it terminal-local.
10859 * terminal.c (create_terminal): Initialize it.
10861 * xselect.c: Support for clipboard managers.
10862 (Vselection_alist): Move to termhooks.h as terminal-local var.
10863 (LOCAL_SELECTION): New macro.
10864 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
10865 (symbol_to_x_atom): Remove gratuitous arg.
10866 (x_handle_selection_request, lisp_data_to_selection_data)
10867 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
10868 (x_own_selection, x_get_local_selection, x_convert_selection):
10869 New arg, specifying work frame. Use terminal-local Vselection_alist.
10870 (some_frame_on_display): Delete unused function.
10871 (Fx_own_selection_internal, Fx_get_selection_internal)
10872 (Fx_disown_selection_internal, Fx_selection_owner_p)
10873 (Fx_selection_exists_p): New optional frame arg.
10874 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
10875 (x_handle_selection_clear): Don't treat other terminals with the
10876 same keyboard specially. Use the terminal-local Vselection_alist.
10877 (x_clear_frame_selections): Use Frun_hook_with_args.
10879 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
10881 * xterm.h: Add support for those atoms.
10883 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
10885 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
10886 (converted_selections, conversion_fail_tag): New global variables.
10887 (x_selection_request_lisp_error): Free the above.
10888 (x_get_local_selection): Remove unnecessary code.
10889 (x_reply_selection_request): Args changed; handle arbitrary array
10890 of converted selections stored in converted_selections.
10891 Separate the XChangeProperty and SelectionNotify steps.
10892 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
10893 (x_convert_selection): New function.
10894 (x_handle_selection_event): Simplify.
10895 (x_get_foreign_selection): Don't ignore incoming requests while
10896 waiting for an answer; this will fail when we implement
10897 SAVE_TARGETS, and seems unnecessary anyway.
10898 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
10899 (Vx_sent_selection_functions): Doc fix.
10901 2011-05-26 Leo Liu <sdl.web@gmail.com>
10903 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
10905 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10907 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
10909 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
10910 for fringe update if it has periodic bitmap.
10911 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
10912 and fringe_bitmap_periodic_p.
10914 * fringe.c (get_fringe_bitmap_data): New function.
10915 (draw_fringe_bitmap_1, update_window_fringes): Use it.
10916 (update_window_fringes): Record periodicity of fringe bitmap in glyph
10917 row. Mark glyph row for fringe update if periodicity changed.
10919 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
10920 for fringe update unless it has periodic bitmap.
10922 2011-05-25 Kenichi Handa <handa@m17n.org>
10924 * xdisp.c (get_next_display_element): Set correct it->face_id for
10925 a static composition.
10927 2011-05-24 Leo Liu <sdl.web@gmail.com>
10929 * deps.mk (fns.o):
10930 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
10932 * fns.c (crypto_hash_function, Fsha1): New function.
10933 (Fmd5): Use crypto_hash_function.
10934 (syms_of_fns): Add Ssha1.
10936 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
10938 * gnutls.c: Remove unused macros.
10939 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
10940 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
10941 Remove macros that are defined and never used.
10942 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
10944 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
10946 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
10947 (Fx_get_selection_internal): Minor cleanup.
10948 (Fx_own_selection_internal): Rename arguments for consistency with
10949 select.el.
10951 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
10953 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
10955 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
10957 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
10959 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10961 * dispnew.c (scrolling_window): Don't exclude the case that the
10962 last enabled row in the desired matrix touches the bottom boundary.
10964 2011-05-21 Glenn Morris <rgm@gnu.org>
10966 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
10967 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
10968 and add some more files.
10970 2011-05-20 Eli Zaretskii <eliz@gnu.org>
10972 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
10973 report_file_error introduced by the change from 2011-05-07.
10975 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
10977 * systime.h (Time): Define only if emacs is defined.
10978 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
10979 where the include path doesn't have X11/X.h by default. See
10980 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
10982 2011-05-20 Kenichi Handa <handa@m17n.org>
10984 * composite.c (find_automatic_composition): Fix previous change.
10986 2011-05-20 Glenn Morris <rgm@gnu.org>
10988 * lisp.mk: New file, split from Makefile.in.
10989 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
10990 (shortlisp): Remove.
10991 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
10993 2011-05-19 Glenn Morris <rgm@gnu.org>
10995 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
10996 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
10997 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
10998 (lisp): Set the order to that of loadup.el.
10999 (shortlisp): Make it a copy of $lisp.
11000 (SOME_MACHINE_LISP): Remove.
11001 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
11002 Use just $shortlisp, not $SOME_MACHINE_LISP too.
11004 2011-05-18 Kenichi Handa <handa@m17n.org>
11006 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
11007 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
11008 (find_automatic_composition): Mostly rewrite for efficiency.
11010 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
11012 * makefile.w32-in: Update dependencies.
11014 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
11016 * menu.c: Include limits.h (fixes the MS-Windows build broken by
11017 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
11019 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
11021 Fix some integer overflow issues, such as string length overflow.
11023 * insdel.c (count_size_as_multibyte): Check for string overflow.
11025 * character.c (lisp_string_width): Check for string overflow.
11026 Use EMACS_INT, not int, for string indexes and lengths; in
11027 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
11028 the resulting string length overflows an EMACS_INT; instead,
11029 report a string overflow if no precision given. When checking for
11030 precision exhaustion, use a check that cannot possibly have
11031 integer overflow. (Bug#8675)
11032 * character.h (lisp_string_width): Adjust to new signature.
11034 * alloc.c (string_overflow): New function.
11035 (Fmake_string): Use it. This doesn't change behavior, but saves
11036 a few bytes and will simplify future changes.
11037 * character.c (string_escape_byte8): Likewise.
11038 * lisp.h (string_overflow): New decl.
11040 Fixups, following up to the user-interface timestamp change.
11041 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
11042 for UI timestamps, instead of unsigned long.
11043 * msdos.c (mouse_get_pos): Likewise.
11044 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
11045 * w32gui.h (Time): Define by including "systime.h" rather than by
11046 declaring it ourselves. (Bug#8664)
11048 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
11049 * image.c (clear_image_cache): Likewise.
11051 * term.c (term_mouse_position): Don't assume time_t wraparound.
11053 Be more systematic about user-interface timestamps.
11054 Before, the code sometimes used 'Time', sometimes 'unsigned long',
11055 and sometimes 'EMACS_UINT', to represent these timestamps.
11056 This change causes it to use 'Time' uniformly, as that's what X uses.
11057 This makes the code easier to follow, and makes it easier to catch
11058 integer overflow bugs such as Bug#8664.
11059 * frame.c (Fmouse_position, Fmouse_pixel_position):
11060 Use Time, not unsigned long, for user-interface timestamps.
11061 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
11062 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
11063 * keyboard.h (last_event_timestamp): Likewise.
11064 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
11065 * menu.h (xmenu_show): Likewise.
11066 * term.c (term_mouse_position): Likewise.
11067 * termhooks.h (struct input_event.timestamp): Likewise.
11068 (struct terminal.mouse_position_hook): Likewise.
11069 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
11070 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
11071 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
11072 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
11073 what it was before.
11074 * menu.h, termhooks.h: Include "systime.h", for Time.
11076 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
11077 Don't assume that the difference between two unsigned long values
11078 can fit into an integer. At this point, we know button_down_time
11079 <= event->timestamp, so the difference must be nonnegative, so
11080 there's no need to cast the result if double-click-time is
11081 nonnegative, as it should be; check that it's nonnegative, just in
11082 case. This bug is triggered when events are more than 2**31 ms
11083 apart (about 25 days). (Bug#8664)
11085 * xselect.c (last_event_timestamp): Remove duplicate decl.
11086 (x_own_selection): Remove needless cast to unsigned long.
11088 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
11089 that always fit in int. Use a sentinel instead of a counter, to
11090 avoid a temp and to allay GCC's concerns about possible int overflow.
11091 * frame.h (struct frame): Use int for menu_bar_items_used
11092 instead of EMACS_INT, since it always fits in int.
11094 * menu.c (grow_menu_items): Check for int overflow.
11096 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
11098 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
11099 Before, the code was not consistent. These values cannot exceed
11100 2**31 - 1 so there's no need to make them unsigned.
11101 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
11102 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
11103 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
11104 as modifiers.
11105 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
11107 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
11108 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
11109 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
11110 presumably because the widths might not match.
11112 * window.c (size_window): Avoid needless test at loop start.
11114 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
11116 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
11118 2011-05-12 Drew Adams <drew.adams@oracle.com>
11120 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
11122 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11124 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
11125 `width' to `bar_area_x' and `bar_area_width', respectively.
11126 (x_scroll_run): Take account of fringe background extension.
11128 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
11129 Rename local vars `left' and `width' to `bar_area_x' and
11130 `bar_area_width', respectively.
11131 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
11132 background extension.
11134 2011-05-10 Jim Meyering <meyering@redhat.com>
11136 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
11138 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
11140 * image.c (Finit_image_library): Return t for built-in image types,
11141 like pbm and xbm. (Bug#8640)
11143 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
11145 * w32menu.c (set_frame_menubar): Fix submenu allocation.
11147 2011-05-07 Eli Zaretskii <eliz@gnu.org>
11149 * w32console.c (Fset_screen_color): Doc fix.
11150 (Fget_screen_color): New function.
11151 (syms_of_ntterm): Defsubr it.
11153 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
11154 unlink the temporary file if Fcall_process didn't create it in the
11155 first place.
11156 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
11157 child process will be redirected to a file specified with `:file'.
11158 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
11159 cue to call_process_cleanup not to close that handle.
11161 2011-05-07 Ben Key <bkey76@gmail.com>
11163 * makefile.w32-in: The bootstrap-temacs rule now makes use of
11164 one of two shell specific rules, either bootstrap-temacs-CMD or
11165 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
11166 to the previous implementation of the bootstrap-temacs rule.
11167 The bootstrap-temacs-CMD rule is similar to the previous
11168 implementation of the bootstrap-temacs rule except that it
11169 makes use of the ESC_CFLAGS variable instead of the CFLAGS
11170 variable.
11172 These changes, along with some changes to nt/configure.bat,
11173 nt/gmake.defs, and nt/nmake.defs, are required to extend my
11174 earlier fix to add support for --cflags and --ldflags options
11175 that include quotes so that it works whether make uses cmd or
11176 sh as the shell.
11178 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
11180 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
11181 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
11182 is a constant.
11183 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
11184 a string. Handle both cases.
11185 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
11186 (Fdbus_register_method): Use Qinvalid_function.
11188 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
11190 * makefile.w32-in: Update dependencies.
11191 (LISP_H): Add inttypes.h and stdin.h.
11192 (PROCESS_H): Add unistd.h.
11194 2011-05-06 Eli Zaretskii <eliz@gnu.org>
11196 * lread.c: Include limits.h (fixes the MS-Windows build broken by
11197 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
11199 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
11201 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
11203 * term.c (vfatal): Remove stray call to va_end.
11204 It's not needed and the C Standard doesn't allow it here anyway.
11206 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
11207 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
11209 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
11210 bytes.
11212 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
11214 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
11216 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
11218 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
11220 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
11222 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
11223 * charset.c (Fdefine_charset_internal): Don't initialize
11224 charset.code_space[15]. The value was garbage, on hosts with
11225 32-bit int (Bug#8600).
11227 * lread.c (read_integer): Be more consistent with string-to-number.
11228 Use string_to_number to do the actual conversion; this avoids
11229 rounding errors and fixes some other screwups. Without this fix,
11230 for example, #x1fffffffffffffff was misread as -2305843009213693952.
11231 (digit_to_number): Move earlier, for benefit of read_integer.
11232 Return -1 if the digit is out of range for the base, -2 if it is
11233 not a digit in any supported base. (Bug#8602)
11235 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
11237 * dispnew.c (scrolling_window): Return 1 if we scrolled,
11238 to match comment at start of function. This also removes a
11239 GCC warning about overflow in a 32+64-bit port.
11241 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
11243 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
11244 Reported by Stefan Monnier in
11245 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
11246 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
11247 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
11249 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
11250 (EMACS_UINTPTR): Likewise, with uintptr_t.
11252 * lisp.h: Prefer 64-bit EMACS_INT if available.
11253 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
11254 on 32-bit hosts that have 64-bit int, so that they can access
11255 large files.
11256 However, temporarily disable this change unless the temporary
11257 symbol WIDE_EMACS_INT is defined.
11259 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
11261 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
11262 This removes an assumption that EMACS_INT and long are the same
11263 width as pointers. The assumption is true for Emacs porting targets
11264 now, but we want to make other targets possible.
11265 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
11266 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
11267 In the rest of the code, change types of integers that hold casted
11268 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
11269 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
11270 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
11271 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
11272 No need to cast type when ORing.
11273 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
11274 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
11275 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
11276 assume EMACS_INT is the same width as char *.
11277 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
11278 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
11279 Remove no-longer-needed casts.
11280 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
11281 (xg_tool_bar_help_callback, xg_make_tool_item):
11282 Use EMACS_INTPTR to hold an integer
11283 that will be cast to void *; this can avoid a GCC warning
11284 if EMACS_INT is not the same width as void *.
11285 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
11286 * xdisp.c (display_echo_area_1, resize_mini_window_1):
11287 (current_message_1, set_message_1):
11288 Use a local to convert to proper width without a cast.
11289 * xmenu.c (dialog_selection_callback): Likewise.
11291 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
11292 Also, don't assume VALBITS / RAND_BITS is less than 5,
11293 and don't rely on undefined behavior when shifting a 1 left into
11294 the sign bit.
11295 * lisp.h (get_random): Change signature to match.
11297 * lread.c (hash_string): Use size_t, not int, for hash computation.
11298 Normally we prefer signed values; but hashing is special, because
11299 it's better to use unsigned division on hash table sizes so that
11300 the remainder is nonnegative. Also, size_t is the natural width
11301 for hashing into memory. The previous code used 'int', which doesn't
11302 retain enough info to hash well into very large tables.
11303 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
11305 * dbusbind.c: Don't possibly lose pointer info when converting.
11306 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
11307 Use XPNTR rather than XHASH, so that the high-order bits of
11308 the pointer aren't lost when converting through void *.
11310 * eval.c (Fautoload): Don't double-shift a pointer.
11312 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
11314 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
11316 * gnutls.c (DEF_GNUTLS_FN):
11317 * image.c (DEF_IMGLIB_FN): Make function pointers static.
11319 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
11321 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
11322 marker. (Bug#8610)
11324 2011-05-05 Eli Zaretskii <eliz@gnu.org>
11326 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
11327 New version that can reserve upto 2GB of heap space.
11329 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
11331 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
11333 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
11335 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
11336 `gnutls_certificate_set_x509_key_file'.
11338 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
11340 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
11341 Update dependencies.
11343 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
11345 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
11346 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
11347 Remove unused parameter `fildes'.
11348 * process.c (read_process_output, send_process): Don't pass it.
11350 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
11352 Fix previous change: the library cache is defined in w32.c.
11353 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
11354 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
11356 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
11358 Implement dynamic loading of GnuTLS on Windows.
11360 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
11361 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
11362 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
11363 Declare.
11365 * gnutls.c (Qgnutls_dll): Define.
11366 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
11367 (gnutls_*): Declare function pointers.

11369 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
11370 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
11371 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
11372 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
11373 (emacs_gnutls_write, emacs_gnutls_read)
11374 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
11375 (Fgnutls_available_p): New function.
11376 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
11377 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
11378 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
11380 * image.c: Include w32.h.
11381 (Vimage_type_cache): Delete.
11382 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
11383 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
11384 (w32_delayed_load): Move to w32.c.
11386 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
11388 * w32.c (QCloaded_from, Vlibrary_cache): Define.
11389 (w32_delayed_load): Move from image.c. When loading a library, record
11390 its filename in the :loaded-from property of the library id.
11391 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
11392 Initialize and staticpro them.
11393 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
11395 * process.c: Include lisp.h before w32.h, not after.
11396 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
11397 instead of gnutls_record_check_pending.
11399 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
11401 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
11403 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
11404 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
11405 as passed in.
11407 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
11409 * xterm.c (x_set_frame_alpha): Do not set property on anything

11425 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
11426 (Qgnutls_bootprop_callbacks_verify): Make static.
11428 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
11430 * callproc.c: Indentation fixup.
11432 * sysdep.c (wait_for_termination_1): Make static.
11433 (wait_for_termination, interruptible_wait_for_termination):
11434 Move after wait_for_termination_1.
11436 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
11438 * sysdep.c (interruptible_wait_for_termination): New function
11439 which is like wait_for_termination, but allows keyboard
11440 interruptions.
11442 * callproc.c (Fcall_process): Add (:file "file") as an option for
11443 the STDOUT buffer.
11444 (Fcall_process_region): Ditto.
11446 2011-04-30 Eli Zaretskii <eliz@gnu.org>
11448 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
11449 rather than `XVECTOR (FOO)->size'.
11451 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
11452 inttypes.h, as a gnulib replacement is used if it not available in
11453 system headers.
11455 2011-04-21 Eli Zaretskii <eliz@gnu.org>
11457 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
11458 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
11459 of MOST_POSITIVE_FIXNUM. (Bug#8528)

11467 charbuf for the composition carryover bytes.
11469 2011-04-21 Eli Zaretskii <eliz@gnu.org>

11472 aborting when %lld or %lll format is passed.
11473 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
11474 %llo or %llx format is passed. (Bug#8545)
11476 * window.c (window_scroll_line_based): Use a marker instead of
11477 simple variables to record original value of point. (Bug#7952)
11479 * doprnt.c (doprnt): Fix the case where a multibyte sequence
11480 produced by %s or %c overflows available buffer space. (Bug#8545)
11482 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
11484 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

11496 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
11497 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
11499 2011-04-28 Eli Zaretskii <eliz@gnu.org>
11501 * doprnt.c (doprnt): Don't return value smaller than the buffer
11502 size if the message was truncated. (Bug#8545).
11504 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
11506 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
11507 (Fx_window_property): #if-0 the whole functions, not just the bodies.
11509 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
11511 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
11513 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
11515 * makefile.w32-in: Update dependencies.

11519 Improve `doprnt' and its usage. (Bug#8545)
11520 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
11521 `format_end'. Remove support for %l as a conversion specifier.
11522 Don't use xrealloc. Improve diagnostics when the %l size modifier
11523 is used. Update the commentary.
11525 * eval.c (verror): Simplify calculation of size_t.
11527 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
11528 messages.
11530 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
11532 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
11533 change.
11535 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
11537 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
11538 This makes this file independent of the recent pseudovector change.
11540 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
11542 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
11544 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
11545 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
11546 Remove unused local.
11547 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
11549 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
11550 GCC 4.6.0 optimizes based on type-based alias analysis.
11551 For example, if b is of type struct buffer * and v of type struct
11552 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
11553 != &v->size, and therefore "v->size = 1; b->size = 2; return
11554 v->size;" must therefore return 1. This assumption is incorrect
11555 for Emacs, since it type-puns struct Lisp_Vector * with many other
11556 types. To fix this problem, this patch adds a new type struct
11557 vectorlike_header that documents the constraints on layout of vectors
11558 and pseudovectors, and helps optimizing compilers not get fooled
11559 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
11560 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
11561 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
11562 the size member.
11563 (XSETPVECTYPE): Rewrite in terms of new macro.
11564 (XSETPVECTYPESIZE): New macro, specifying both type and size.
11565 This is a bit clearer, and further avoids the possibility of
11566 undesirable aliasing.
11567 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
11568 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
11569 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
11570 since Lisp_Subr is a special case (no "next" field).
11571 (ASIZE): Now uses header.size rather than size.
11572 All previous uses of XVECTOR (foo)->size replaced to use this macro,
11573 to avoid the hassle of writing XVECTOR (foo)->header.size.
11574 (struct vectorlike_header): New type.
11575 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
11576 object, to help avoid aliasing.
11577 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
11578 (SUBRP): Likewise, since Lisp_Subr is a special case.
11579 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
11580 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
11581 (struct Lisp_Hash_Table): Combine first two members into a single
11582 struct vectorlike_header member. All uses of "size" and "next" members
11583 changed to be "header.size" and "header.next".
11584 * buffer.h (struct buffer): Likewise.
11585 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
11586 * frame.h (struct frame): Likewise.
11587 * process.h (struct Lisp_Process): Likewise.
11588 * termhooks.h (struct terminal): Likewise.
11589 * window.c (struct save_window_data, struct saved_window): Likewise.
11590 * window.h (struct window): Likewise.
11591 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
11592 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
11593 * buffer.c (init_buffer_once): Likewise.
11594 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
11595 special case.
11596 * process.c (Fformat_network_address): Use local var for size,
11597 for brevity.
11599 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
11601 Make the Lisp reader and string-to-float more consistent (Bug#8525)
11602 * data.c (atof): Remove decl; no longer used or needed.
11603 (digit_to_number): Move to lread.c.
11604 (Fstring_to_number): Use new string_to_number function, to be
11605 consistent with how the Lisp reader treats infinities and NaNs.
11606 Do not assume that floating-point numbers represent EMACS_INT
11607 without losing information; this is not true on most 64-bit hosts.
11608 Avoid double-rounding errors, by insisting on integers when
11609 parsing non-base-10 numbers, as the documentation specifies.
11610 * lisp.h (string_to_number): New decl, replacing ...
11611 (isfloat_string): Remove.
11612 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
11613 (read1): Do not accept +. and -. as integers; this
11614 appears to have been a coding error. Similarly, do not accept
11615 strings like +-1e0 as floating point numbers. Do not report
11616 overflow for integer overflows unless the base is not 10 which
11617 means we have no simple and reliable way to continue.
11618 Break out the floating-point parsing into a new
11619 function string_to_number, so that Fstring_to_number parses
11620 floating point numbers consistently with the Lisp reader.
11621 (digit_to_number): Move here from data.c. Make it static inline.
11622 (E_CHAR, EXP_INT): Remove, replacing with ...
11623 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
11624 (string_to_number): New function, replacing isfloat_string.
11625 This function checks for valid syntax and produces the resulting
11626 Lisp float number too. Rework it so that string-to-number
11627 no longer mishandles examples like "1.0e+". Use strtoumax,
11628 so that overflow for non-base-10 numbers is reported only when
11629 there's no portable and simple way to convert to floating point.
11631 * textprop.c (set_text_properties_1): Rewrite for clarity,
11632 and to avoid GCC warning about integer overflow.
11634 * intervals.h (struct interval): Use EMACS_INT for members
11635 where EMACS_UINT might cause problems. See
11636 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
11637 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
11638 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
11639 All uses changed.
11640 (offset_intervals): Tell GCC not to worry about length overflow
11641 when negating a negative length.
11643 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
11644 (overrun_check_free): Likewise.
11646 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
11647 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
11648 word size.
11650 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
11651 (gnutls_make_error): Rename local to avoid shadowing.
11652 (gnutls_emacs_global_deinit): ifdef out; not used.
11653 (Fgnutls_boot): Use const for pointer to readonly storage.
11654 Comment out unused local. Fix pointer signedness problems.
11656 * lread.c (openp): Don't stuff size_t into an 'int'.
11657 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
11658 about possible signed overflow.
11660 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
11661 (GDK_KEY_g): Don't define if already defined.
11662 (xg_prepare_tooltip): Avoid pointer signedness problem.
11663 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
11665 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
11666 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
11668 * xfns.c (Fx_window_property): Simplify a bit,
11669 to make a bit faster and to avoid GCC 4.6.0 warning.
11670 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
11672 * fns.c (internal_equal): Don't assume size_t fits in int.
11674 * alloc.c (compact_small_strings): Tighten assertion a little.
11676 Replace pEd with more-general pI, and fix some printf arg casts.
11677 * lisp.h (pI): New macro, generalizing old pEd macro to other
11678 conversion specifiers. For example, use "...%"pI"d..." rather
11679 than "...%"pEd"...".
11680 (pEd): Remove. All uses replaced with similar uses of pI.
11681 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
11682 * alloc.c (check_pure_size): Don't overflow by converting size to int.
11683 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
11684 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
11685 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
11686 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
11687 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
11688 64-bit hosts.
11689 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
11690 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
11691 * print.c (safe_debug_print, print_object): Likewise.
11692 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
11693 to int.
11694 Use pI instead of if-then-else-abort. Use %p to avoid casts,
11695 avoiding the 0 flag, which is not portable.
11696 * process.c (Fmake_network_process): Use pI to avoid cast.
11697 * region-cache.c (pp_cache): Likewise.
11698 * xdisp.c (decode_mode_spec): Likewise.
11699 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
11700 behavior on 64-bit hosts with printf arg.
11701 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
11702 (x_stop_queuing_selection_requests): Likewise.
11703 (x_get_window_property): Don't truncate byte count to an 'int'
11704 when tracing.
11706 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
11707 here, since it parses constructs like leading '-' and spaces,
11708 which are not wanted; and it overflows with large numbers.
11709 Instead, simply match F[0-9]+, which is what is wanted anyway.
11711 * alloc.c: Remove unportable assumptions about struct layout.
11712 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
11713 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
11714 (allocate_vectorlike, make_pure_vector): Use the new macros,
11715 plus offsetof, to remove unportable assumptions about struct layout.
11716 These assumptions hold on all porting targets that I know of, but
11717 they are not guaranteed, they're easy to remove, and removing them
11718 makes further changes easier.
11720 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
11721 This doesn't fix a bug but makes the code clearer.
11722 (string_overrun_cookie): Now const. Use initializers that
11723 don't formally overflow signed char, to avoid warnings.
11724 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
11725 can cause Emacs to crash when string overrun checking is enabled.
11726 (allocate_buffer): Don't assume sizeof (struct buffer) is a
11727 multiple of sizeof (EMACS_INT); it need not be, if
11728 alignof(EMACS_INT) < sizeof (EMACS_INT).
11729 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
11731 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
11733 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
11735 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
11737 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
11738 supposed to be handshaking. (Bug#8556)
11739 Reported by Paul Eggert <eggert@cs.ucla.edu>.
11741 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
11743 * lisp.h (Qdebug): List symbol.
11744 * eval.c (Qdebug): Restore global linkage.
11745 * keyboard.c (debug-on-event): New variable.
11746 (handle_user_signal): Break into debugger when debug-on-event
11747 matches the current signal symbol.
11749 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
11751 * alloc.c (check_sblock, check_string_bytes)
11752 (check_string_free_list): Convert to standard C.
11754 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
11756 * w32.c (emacs_gnutls_push): Fix typo.
11758 2011-04-25 Eli Zaretskii <eliz@gnu.org>
11760 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
11761 "cast to pointer from integer of different size".
11763 Improve doprnt and its use in verror. (Bug#8545)
11764 * doprnt.c (doprnt): Document the set of format control sequences
11765 supported by the function. Use SAFE_ALLOCA instead of always
11766 using `alloca'.
11768 * eval.c (verror): Don't limit the buffer size at size_max-1, that
11769 is one byte too soon. Don't use xrealloc; instead xfree and
11770 xmalloc anew.
11772 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
11774 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
11775 callbacks stage.
11777 * gnutls.c: Renamed global_initialized to
11778 gnutls_global_initialized. Added internals for the
11779 :verify-hostname-error, :verify-error, and :verify-flags
11780 parameters of `gnutls-boot' and documented those parameters in the
11781 docstring. Start callback support.
11782 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
11783 unless a fatal error occurred. Call gnutls_alert_send_appropriate
11784 on error. Return error code.
11785 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
11786 (emacs_gnutls_read): Likewise.
11787 (Fgnutls_boot): Return handshake error code.
11788 (emacs_gnutls_handle_error): New function.
11789 (wsaerror_to_errno): Likewise.

11792 (emacs_gnutls_push): Likewise.
11794 * w32.c (emacs_gnutls_pull): New function for GnuTLS on Woe32.
11795 (emacs_gnutls_push): Likewise.
11797 2011-04-24 Claudio Bley <claudio.bley@gmail.com> (tiny change)
11799 * process.c (wait_reading_process_output): Check if GnuTLS
11800 buffered some data internally if no FDs are set for TLS
11801 connections.
11803 * makefile.w32-in (OBJ2): Add gnutls.$(O).
11804 (LIBS): Link to USER_LIBS.

11810 display_replaced_before_p argument into display_replaced_p, to
11811 make it consistent with the commentary. Fix typos in the
11812 commentary.
11814 * textprop.c (syms_of_textprop): Remove dead code.
11815 (copy_text_properties): Delete obsolete commentary about an
11816 interface that was deleted long ago. Fix typos in the description
11817 of arguments.

11820 to changes in oldXMenu/XMenu.h from 2011-04-16.
11821 <menu_help_message, prev_menu_help_message>: Constify.
11822 (IT_menu_make_room): menu->help_text is now `const char **';
11823 adjust.

11826 to changes in oldXMenu/XMenu.h from 2011-04-16.
11827 (struct XMenu): Declare `help_text' `const char **'.
11829 * xfaces.c <Qunspecified>: Make extern again.
11831 * syntax.c: Include sys/types.h before including regex.h, as
11832 required by POSIX.
11834 * doc.c (get_doc_string): Improve the format passed to `error'.
11836 * doprnt.c (doprnt): Improve commentary.
11838 * term.c (init_tty) [MSDOS]: Fix 1st argument to maybe_fatal.
11840 * Makefile.in (TAGS): Depend on $(M_FILE) and $(S_FILE), and scan
11841 them with etags.
11843 * makefile.w32-in (globals.h): Add a dummy recipe, to make any
11844 changes in globals.h immediately force recompilation.
11845 (TAGS): Depend on $(CURDIR)/m/intel386.h and
11846 $(CURDIR)/s/ms-w32.h.
11847 (TAGS-gmake): Scan $(CURDIR)/m/intel386.h and $(CURDIR)/s/ms-w32.h.
11849 * character.c (Fchar_direction): Function deleted.
11850 (syms_of_character): Don't defsubr it.
11851 <char-direction-table>: Deleted.
11853 2011-04-23 Eli Zaretskii <eliz@gnu.org>
11855 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
11856 * doprnt.c: Include limits.h.
11857 (SIZE_MAX): New macro.
11858 (doprnt): Return a size_t value. 2nd arg is now size_t.
11859 Many local variables are now size_t instead of int or unsigned.
11860 Improve overflow protection. Support `l' modifier for integer
11861 conversions. Support %l conversion. Don't assume an EMACS_INT
11862 argument for integer conversions and for %c.
11864 * lisp.h (doprnt): Restore prototype.
11866 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
11867 $(SRC)/character.h.
11869 * Makefile.in (base_obj): Add back doprnt.o.
11871 * deps.mk (doprnt.o): Add back prerequisites.
11872 (callint.o): Depend on character.h.
11874 * eval.c (internal_lisp_condition_case): Include the handler
11875 representation in the error message.
11876 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
11877 when breaking from the loop.
11879 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
11881 * callint.c (Fcall_interactively): When displaying error message
11882 about invalid control letter, pass the character's codepoint, not
11883 a pointer to its multibyte form. Improve display of the character
11884 in octal and display also its hex code.
11886 * character.c (char_string): Use %x to display the (unsigned)
11887 codepoint of an invalid character, to avoid displaying a bogus
11888 negative value.
11890 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
11891 `error', not SYMBOL_NAME itself.
11893 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
11894 character arguments to `error'.
11896 * charset.c (check_iso_charset_parameter): Fix incorrect argument
11897 to `error' in error message about FINAL_CHAR argument. Make sure
11898 FINAL_CHAR is a character, and use %c when it is passed as
11899 argument to `error'.
11901 2011-04-23 Eli Zaretskii <eliz@gnu.org>
11903 * s/ms-w32.h (localtime): Redirect to sys_localtime.
11905 * w32.c: Include <time.h>.

11925 to <= INT_MAX.
11927 2011-04-18 Chong Yidong <cyd@stupidchicken.com>
11929 * xdisp.c (lookup_glyphless_char_display)
11930 (produce_glyphless_glyph): Handle cons cell entry in
11931 glyphless-char-display.
11932 (Vglyphless_char_display): Document it.

11948 Static checks with GCC 4.6.0 and non-default toolkits.
11950 * s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF): Protoize decl.
11952 * process.c (keyboard_bit_set): Define only if SIGIO.

12088 * nsfont.m: Fixed bugs in ns_get_family and
12089 ns_descriptor_to_entity that were caused by using free to
12090 deallocate memory blocks that were allocated by xmalloc (via

12445 * buffer.c (buffer_count): Remove unused var.
12447 * bidi.c (bidi_dump_cached_states): Mark as externally visible,
12448 so that it's not optimized away.
12449 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
12450 * dispextern.h (bidi_dump_cached_states): Remove, since it's
12451 exported only to the debugger.
12453 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
12454 * atimer.h (run_all_atimers): Remove; not exported.
12456 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
12457 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
12458 was inaccessible from Lisp.
12459 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
12460 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
12462 alloc.c: Import and export fewer symbols, and remove unused items.
12463 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
12464 is defined.

12466 it's not optimized away by whole-program optimization.
12467 (message_enable_multibyte, free_misc): Remove.
12468 (catchlist, handlerlist, mark_backtrace):
12469 Declare only if BYTE_MARK_STACK.

12479 (mark_backtrace): Define only if BYTE_MARK_STACK.
12480 * xdisp.c (message_enable_multibyte): Now static.
12482 Declare Lisp_Object Q* variables to be 'static' if not exported.
12483 This makes it easier for human readers (and static analyzers)
12484 to see whether these variables are used from other modules.
12485 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
12486 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
12487 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:

12495 Remove decls of unexported vars.
12496 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
12498 * lisp.h (DEFINE_FUNC): Make sname 'static'.
12500 Make Emacs functions such as Fatom 'static' by default.
12501 This makes it easier for human readers (and static analyzers)
12502 to see whether these functions can be called from other modules.
12503 DEFUN now defines a static function. To make the function external
12504 so that it can be used in other C modules, use the new macro DEFUE.
12505 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
12506 (Finit_image_library):
12507 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
12508 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
12509 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
12510 Remove decls, since these functions are now static.
12511 (Funintern, Fget_internal_run_time): New decls, since these functions
12512 were already external.
12514 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
12515 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

12521 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
12522 Mark functions with DEFUE instead of DEFUN,
12523 if they are used in other modules.
12524 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
12525 decls for now-static functions.
12526 * buffer.h (Fdelete_overlay): Remove decl.
12527 * callproc.c (Fgetenv_internal): Mark as internal.
12528 * composite.c (Fremove_list_of_text_properties): Remove decl.

12536 * image.c (Finit_image_library): New forward static decl.
12537 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
12538 * intervals.h (Fprevious_property_change):
12539 (Fremove_list_of_text_properties): Remove decls.
12540 * keyboard.c (Fthis_command_keys): Remove decl.
12541 (Fcommand_execute): New forward static decl.

12557 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
12559 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
12560 change. (Bug#8496)
12562 2011-04-13 Eli Zaretskii <eliz@gnu.org>
12564 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
12565 when at ZV. (Bug#8487)
12567 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
12569 * charset.c (Fclear_charset_maps): Use xfree instead of free.
12570 (Bug#8437)
12571 * keyboard.c (parse_tool_bar_item): Likewise.
12572 * sound.c (sound_cleanup, alsa_close): Likewise.
12573 * termcap.c (tgetent): Likewise.
12574 * xfns.c (x_default_font_parameter): Likewise.
12575 * xsettings.c (read_and_apply_settings): Likewise.
12577 * alloc.c (overrun_check_malloc, overrun_check_realloc)
12578 (overrun_check_free): Protoize.
12580 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
12582 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
12583 since callers should never pass a negative size.
12584 Change the signature to match that of plain 'read' and 'write'; see
12585 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
12586 * lisp.h: Update prototypes of emacs_write and emacs_read.
12588 2011-04-11 Eli Zaretskii <eliz@gnu.org>
12590 * xdisp.c (redisplay_window): Don't try to determine the character
12591 position of the scroll margin if the window start point w->startp
12592 is outside the buffer's accessible region. (Bug#8468)
12594 2011-04-10 Eli Zaretskii <eliz@gnu.org>
12596 Fix write-region and its subroutines for buffers > 2GB.
12597 * fileio.c (a_write, e_write): Modify declaration of arguments and
12598 local variables to support buffers larger than 2GB.
12599 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
12601 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
12602 argument, local variables, and return value.
12604 * lisp.h: Update prototypes of emacs_write and emacs_read.
12606 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
12608 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
12610 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
12612 Fix more problems found by GCC 4.6.0's static checks.
12614 * xdisp.c (vmessage): Use a better test for character truncation.
12616 * charset.c (load_charset_map): <, not <=, for optimization,
12617 and to avoid potential problems with integer overflow.
12618 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
12619 * casetab.c (set_identity, shuffle): Likewise.
12620 * editfns.c (Fformat): Likewise.
12621 * syntax.c (skip_chars): Likewise.
12623 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
12624 This also lets GCC 4.6.0 generate slightly better loop code.
12626 * callint.c (Fcall_interactively): <, not <=, for optimization.
12627 (Fcall_interactively): Count the number of arguments produced,
12628 not the number of arguments given. This is simpler and lets GCC
12629 4.6.0 generate slightly better code.
12631 * ftfont.c: Distingish more carefully between FcChar8 and char.
12632 The previous code passed unsigned char * to a functions like
12633 strlen and xstrcasecmp that expect char *, which does not
12634 conform to the C standard.
12635 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
12636 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
12637 char * when the C standard requires it.
12639 * keyboard.c (read_char): Remove unused var.
12641 * eval.c: Port to Windows vsnprintf (Bug#8435).
12642 Include <limits.h>.
12643 (SIZE_MAX): Define if the headers do not.
12644 (verror): Do not give up if vsnprintf returns a negative count.
12645 Instead, grow the buffer. This ports to Windows vsnprintf, which
12646 does not conform to C99. Problem reported by Eli Zaretskii.
12647 Also, simplify the allocation scheme, by avoiding the need for
12648 calling realloc, and removing the ALLOCATED variable.
12650 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
12652 Remove invocations of doprnt, as Emacs now uses vsnprintf.
12653 But keep the doprint source code for now, as we might revamp it
12654 and use it again (Bug#8435).
12655 * lisp.h (doprnt): Remove.
12656 * Makefile.in (base_obj): Remove doprnt.o.
12657 * deps.mk (doprnt.o): Remove.
12659 error: Print 32- and 64-bit integers portably (Bug#8435).
12660 Without this change, on typical 64-bit hosts error ("...%d...", N)
12661 was used to print both 32- and 64-bit integers N, which relied on
12662 undefined behavior.
12663 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
12664 * lisp.h (error, verror): Mark as printf-like functions.
12665 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
12666 Report overflow in size calculations when allocating printf buffer.
12667 Do not truncate output string at its first null byte.
12668 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
12669 Truncate the output at a character boundary, since vsnprintf does not
12670 do that.
12671 * charset.c (check_iso_charset_parameter): Convert internal
12672 character to string before calling 'error', since %c now has the
12673 printf meaning.
12674 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
12675 overflow when computing char to be passed to 'error'. Do not
12676 pass Lisp_Object to 'error'; pass the integer instead.
12677 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
12678 formatted with plain %d.
12680 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
12682 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
12684 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
12686 * xterm.c (x_catch_errors): Remove duplicate declaration.
12688 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
12690 * xdisp.c, lisp.h (message_nolog): Remove; unused.
12692 2011-04-10 Jim Meyering <meyering@redhat.com>
12694 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
12695 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
12696 return ssize_t not "int", and use size_t as the buffer length.
12697 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
12698 * gnutls.h: Update declarations.
12699 * process.c (read_process_output): Use ssize_t, to match.
12700 (send_process): Likewise.
12702 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
12704 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
12706 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
12708 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
12709 Use unsigned char, to match FcChar8 type definition.
12711 * xterm.c (handle_one_xevent):
12712 * xmenu.c (create_and_show_popup_menu):
12713 * xselect.c (x_decline_selection_request)
12714 (x_reply_selection_request): Avoid type-punned deref of X events.
12716 2011-04-09 Eli Zaretskii <eliz@gnu.org>
12718 Fix some uses of `int' instead of EMACS_INT.
12719 * search.c (string_match_1, fast_string_match)
12720 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
12721 (scan_buffer, find_next_newline_no_quit)
12722 (find_before_next_newline, search_command, Freplace_match)
12723 (Fmatch_data): Make some `int' variables be EMACS_INT.
12725 * xdisp.c (display_count_lines): 3rd argument and return value now
12726 EMACS_INT. All callers changed.
12727 (pint2hrstr): Last argument is now EMACS_INT.
12729 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
12730 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
12731 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
12732 (decode_coding_utf_16, decode_coding_emacs_mule)
12733 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
12734 (decode_coding_ccl, decode_coding_charset)
12735 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
12736 (decode_coding_iso_2022, decode_coding_emacs_mule)
12737 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
12738 <char_offset, last_offset>: Declare EMACS_INT.
12739 (encode_coding_utf_8, encode_coding_utf_16)
12740 (encode_coding_emacs_mule, encode_invocation_designation)
12741 (encode_designation_at_bol, encode_coding_iso_2022)
12742 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
12743 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
12744 Declare EMACS_INT.
12745 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
12746 (encode_invocation_designation): Last argument P_NCHARS is now
12747 EMACS_INT.
12748 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
12749 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
12751 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
12752 All users changed.
12754 * ccl.c (Fccl_execute_on_string): Declare some variables
12755 EMACS_INT.
12757 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
12759 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
12761 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
12763 * process.c (Fformat_network_address): Doc fix.
12765 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)

12769 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
12771 * keyboard.c (read_char): Call Lisp function help-form-show,
12772 instead of using internal_with_output_to_temp_buffer.
12773 (Qhelp_form_show): New var.
12774 (syms_of_keyboard): Use DEFSYM macro.
12776 * print.c (internal_with_output_to_temp_buffer): Function deleted.
12778 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
12780 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
12782 * process.c (Flist_processes): Remove to Lisp.
12783 (list_processes_1): Delete.
12785 2011-04-06 Eli Zaretskii <eliz@gnu.org>
12787 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
12789 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
12791 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
12793 Fix more problems found by GCC 4.6.0's static checks.
12795 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
12797 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
12799 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
12801 * xdisp.c (vmessage): Mark as a printf-like function.
12803 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.

12808 printf-like functions.
12809 (tiff_load): Add casts to remove these marks before passing them
12810 to system-supplied API.
12812 * eval.c (Fsignal): Remove excess argument to 'fatal'.
12814 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
12815 This avoids several warnings with gcc -Wstrict-overflow.
12816 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
12817 directly, rather than having caller test rule sign. This avoids
12818 some unnecessary tests.
12819 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
12820 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
12821 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
12823 * xfont.c (xfont_text_extents): Remove var that was set but not used.
12824 (xfont_open): Avoid unnecessary tests.
12826 * composite.c (composition_gstring_put_cache): Use unsigned integer.
12828 * composite.h, composite.c (composition_gstring_put_cache):
12829 Use EMACS_INT, not int, for length.
12831 * composite.h (COMPOSITION_DECODE_REFS): New macro,
12832 breaking out part of COMPOSITION_DECODE_RULE.
12833 (COMPOSITION_DECODE_RULE): Use it.
12834 * composite.c (get_composition_id): Remove unused local vars,
12835 by using the new macro.
12837 * textprop.c (set_text_properties_1): Change while to do-while,
12838 since the condition is always true at first.
12840 * intervals.c (graft_intervals_into_buffer): Mark var as used.
12841 (interval_deletion_adjustment): Return unsigned value.
12842 All uses changed.
12844 * process.c (list_processes_1, create_pty, read_process_output):
12845 (exec_sentinel): Remove vars that were set but not used.
12846 (create_pty): Remove unnecessary "volatile"s.
12847 (Fnetwork_interface_info): Avoid possibility of int overflow.
12848 (read_process_output): Do adaptive read buffering even if carryover.
12849 (read_process_output): Simplify nbytes computation if buffered.
12851 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
12853 * syntax.c (scan_words): Remove var that was set but not used.
12854 (update_syntax_table): Use unsigned instead of int.
12856 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
12857 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
12858 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
12860 * print.c (print_error_message): Avoid int overflow.
12862 * font.c (font_list_entities): Redo for clarity,
12863 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
12865 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
12866 (font_score): Avoid potential overflow in diff calculation.
12868 * fns.c (substring_both): Remove var that is set but not used.
12869 (sxhash): Redo loop for clarity and to avoid wraparound warning.
12871 * eval.c (funcall_lambda): Rename local to avoid shadowing.
12873 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
12874 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
12875 can always succeed if overflow has undefined behavior.
12877 * search.c (boyer_moore, wordify): Remove vars set but not used.
12878 (wordify): Omit three unnecessary tests.
12880 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
12881 All callers changed. This avoids the need for an unused var.
12883 * casefiddle.c (casify_region): Remove var that is set but not used.
12885 * dired.c (file_name_completion): Remove var that is set but not used.
12887 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
12889 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
12890 (Finsert_file_contents): Remove unnecessary code checking fd.
12892 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
12893 Check for integer overflow on size calculations.
12895 * buffer.c (Fprevious_overlay_change): Remove var that is set
12896 but not used.
12898 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
12899 Remove vars that are set but not used.
12900 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
12901 (timer_check_2): Mark vars as initialized.
12903 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
12905 * image.c (lookup_image): Remove var that is set but not used.
12906 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
12908 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
12909 that are set but not used.
12911 * xfns.c (make_invisible_cursor): Don't return garbage
12912 if XCreateBitmapFromData fails (Bug#8410).
12914 * xselect.c (x_get_local_selection, x_handle_property_notify):
12915 Remove vars that are set but not used.
12917 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
12918 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
12920 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
12921 Remove var that is set but not used.
12922 (scroll_bar_windows_size): Now size_t, not int.
12923 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
12924 Check for overflow.
12926 * xfaces.c (realize_named_face): Remove vars that are set but not used.
12927 (map_tty_color) [!defined MSDOS]: Likewise.
12929 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
12931 * coding.c: Remove vars that are set but not used.
12932 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
12933 All callers changed.
12934 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
12935 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
12936 (decode_coding_charset): Remove vars that are set but not used.
12938 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
12939 that is set but not used.
12941 * print.c (print_object): Remove var that is set but not used.
12943 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
12944 The gnulib version avoids calling malloc in the usual case,
12945 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
12946 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
12947 * filelock.c (current_lock_owner): Likewise.
12948 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
12949 * sysdep.c: Include allocator.h, careadlinkat.h.
12950 (emacs_no_realloc_allocator): New static constant.
12951 (emacs_readlink): New function.
12952 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
12953 ../lib/careadlinkat.h.
12955 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
12957 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
12958 first non-nil return value).
12960 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
12962 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
12963 if not defined (Bug#8403).
12965 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
12967 * xdisp.c (display_count_lines): Remove parameter `start',

12969 (get_char_face_and_encoding): Remove parameter `multibyte_p',
12970 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
12971 (fill_stretch_glyph_string): Remove parameters `row' and `area',
12972 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
12973 and thereabouts. All callers changed.
12974 (get_per_char_metric): Remove parameter `f', unused since
12975 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
12977 2011-04-02 Jim Meyering <meyering@redhat.com>
12979 do not dereference NULL upon failed strdup
12980 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
12981 (ns_get_family): Likewise.
12983 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
12985 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
12987 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
12989 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
12990 later (Bug#8403).
12992 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
12994 Add lexical binding.
12996 * window.c (Ftemp_output_buffer_show): New fun.
12997 (Fsave_window_excursion):
12998 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
13000 * lread.c (lisp_file_lexically_bound_p): New function.
13001 (Fload): Bind Qlexical_binding.
13002 (readevalloop): Remove `evalfun' arg.
13003 Bind Qinternal_interpreter_environment.
13004 (Feval_buffer): Bind Qlexical_binding.
13005 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
13006 Mark as dynamic.
13007 (syms_of_lread): Declare `lexical-binding'.
13009 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
13011 * keyboard.c (eval_dyn): New fun.
13012 (menu_item_eval_property): Use it.
13014 * image.c (parse_image_spec): Use Ffunctionp.
13016 * fns.c (concat, mapcar1): Accept byte-code-functions.
13018 * eval.c (Fsetq): Handle lexical vars.
13019 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
13020 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
13021 (FletX, Flet): Obey lexical binding.
13022 (Fcommandp): Handle closures.
13023 (Feval): New `lexical' arg.
13024 (eval_sub): New function extracted from Feval. Use it almost
13025 everywhere where Feval was used. Look up vars in lexical env.
13026 Handle closures.
13027 (Ffunctionp): Move from subr.el.
13028 (Ffuncall): Handle closures.
13029 (apply_lambda): Remove `eval_flags'.
13030 (funcall_lambda): Handle closures and new byte-code-functions.
13031 (Fspecial_variable_p): New function.
13032 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
13033 but without exporting it to Lisp.
13035 * doc.c (Fdocumentation, store_function_docstring):
13036 * data.c (Finteractive_form): Handle closures.
13038 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
13039 interactive spec.
13041 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
13042 New byte-codes.
13043 (exec_byte_code): New function extracted from Fbyte_code to handle new
13044 calling convention for byte-code-functions. Add new byte-codes.
13046 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
13048 * alloc.c (Fmake_symbol): Init new `declared_special' field.
13050 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
13052 * xdisp.c (redisplay_internal): Fix prototype.
13054 2011-03-31 Eli Zaretskii <eliz@gnu.org>
13056 * xdisp.c (SCROLL_LIMIT): New macro.
13057 (try_scrolling): Use it when setting scroll_limit.
13058 Limit scrolling to 100 screen lines.
13059 (redisplay_window): Even when falling back on "recentering",
13060 position point in the window according to scroll-conservatively,
13061 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
13063 (try_scrolling): When point is above the window, allow searching
13064 as far as scroll_max, or one screenful, to compute vertical
13065 distance from PT to the scroll margin position. This prevents
13066 try_scrolling from unnecessarily failing when
13067 scroll-conservatively is set to a value slightly larger than the
13068 window height. Clean up the case of PT below the margin at bottom
13069 of window: scroll_max can no longer be INT_MAX. When aggressive
13070 scrolling is in use, don't let point enter the opposite scroll
13071 margin as result of the scroll.
13072 (syms_of_xdisp) <scroll-conservatively>: Document the
13073 threshold of 100 lines for never-recentering scrolling.
13075 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
13077 * dispextern.h (move_it_by_lines):
13078 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
13079 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
13080 (message_log_check_duplicate): Remove parameters `prev_bol' and
13081 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
13082 (redisplay_internal): Remove parameter `preserve_echo_area',
13083 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
13085 * indent.c (Fvertical_motion):
13086 * window.c (window_scroll_pixel_based, Frecenter):
13087 Don't pass `need_y_p' to `move_it_by_lines'.
13089 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
13091 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
13092 steal a few bits to be more compact.
13093 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
13094 Remove unneeded casts.
13096 * bytecode.c (Fbyte_code): CAR and CDR can GC.
13098 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
13100 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
13101 binding" message (bug#7967).
13103 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
13105 Fix more problems found by GCC 4.6.0's static checks.
13107 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
13108 Remove unused local var.
13110 * editfns.c (Fmessage_box): Remove unused local var.
13112 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
13113 (note_mode_line_or_margin_highlight, note_mouse_highlight):
13114 Omit unused local vars.
13115 * window.c (shrink_windows): Omit unused local var.
13116 * menu.c (digest_single_submenu): Omit unused local var.
13117 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
13118 Omit unused local var.
13120 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
13121 Don't assume string length fits in int.
13122 (keyremap_step, read_key_sequence): Use size_t for sizes.
13123 (read_key_sequence): Don't check last_real_key_start redundantly.
13125 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
13126 instead of alloca (Bug#8344).
13128 * eval.c (Fbacktrace): Don't assume nargs fits in int.
13129 (Fbacktrace_frame): Don't assume nframes fits in int.
13131 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
13133 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
13134 concerns.
13136 * term.c (produce_glyphless_glyph): Remove unnecessary test.
13138 * cm.c (calccost): Turn while-do into do-while, for clarity.
13140 * keyboard.c (syms_of_keyboard): Use the same style as later
13141 in this function when indexing through an array. This also
13142 works around GCC bug 48267.
13144 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
13146 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
13148 * chartab.c (sub_char_table_ref_and_range): Redo for slight
13149 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
13151 * keyboard.c, keyboard.h (num_input_events): Now size_t.
13152 This avoids undefined behavior on integer overflow, and is a bit
13153 more convenient anyway since it is compared to a size_t variable.
13155 Variadic C functions now count arguments with size_t, not int.
13156 This avoids an unnecessary limitation on 64-bit machines, which
13157 caused (substring ...) to crash on large vectors (Bug#8344).
13158 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
13159 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

13166 (funcall_lambda, mark_backtrace): Likewise.
13167 * fns.c (concat): Likewise.
13168 * frame.c (x_set_frame_parameters): Likewise.
13169 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
13170 0 if not found, not -1. All callers changed.
13172 * alloc.c (garbage_collect): Don't assume stack size fits in int.
13173 (stack_copy_size): Now size_t, not int.
13174 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
13176 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
13178 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
13179 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

13183 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
13184 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

13186 * cmds.c (internal_self_insert):
13187 * editfns.c (general_insert_function):
13188 * keymap.c (push_key_description):
13189 * search.c (Freplace_match):
13190 * xdisp.c (message_dolog, set_message_1): All callers changed.
13192 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
13194 * keyboard.c (safe_run_hook_funcall): New function.
13195 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
13196 don't set the hook to nil, but remove the offending function instead.
13197 (Qcommand_hook_internal): Remove, unused.
13198 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
13199 Vcommand_hook_internal.
13201 * eval.c (enum run_hooks_condition): Remove.
13202 (funcall_nil, funcall_not): New functions.
13203 (run_hook_with_args): Call each function through a `funcall' argument.
13204 Remove `cond' argument, now redundant.
13205 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
13206 (Frun_hook_with_args_until_failure): Adjust accordingly.
13207 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.

13213 * print.c (strout): Remove parameter `multibyte', unused since
13214 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
13216 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
13217 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
13218 All callers changed.
13220 * w32.c (_wsa_errlist): Use braces for struct initializers.
13222 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
13223 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
13224 All callers changed.

13385 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
13387 Fix more problems found by GCC 4.5.2's static checks.
13389 * coding.c (encode_coding_raw_text): Avoid unnecessary test
13390 the first time through the loop, since we know p0 < p1 then.
13391 This also avoids a gcc -Wstrict-overflow warning.
13393 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
13394 leading to a memory leak, possible in functions like
13395 load_charset_map_from_file that can allocate an unbounded number
13396 of objects (Bug#8318).
13398 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
13399 that could (at least in theory) be that large.
13401 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
13402 This is less likely to overflow, and avoids undefined behavior if
13403 overflow does occur. All callers changed. Use strtoul to scan
13404 for the unsigned long integer.
13405 (pint2hrstr): Simplify and tune code slightly.
13406 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

13419 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
13421 * process.c (Fmake_network_process): Use socklen_t, not int,
13422 where POSIX says socklen_t is required in portable programs.
13423 This fixes a porting bug on hosts like 64-bit HP-UX, where
13424 socklen_t is wider than int (Bug#8277).
13425 (Fmake_network_process, server_accept_connection):
13426 (wait_reading_process_output, read_process_output):
13427 Likewise.

13437 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
13439 Make tparam.h and terminfo.c consistent.
13440 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
13441 Include tparam.h instead, since it declares them.
13442 * cm.h (PC): Remove extern decl; tparam.h now does this.
13443 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
13444 * terminfo.c: Include tparam.h, to check interfaces.
13445 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
13446 (tparam): Adjust signature to match interface in tparam.h;
13447 this removes some undefined behavior. Check that outstring and len
13448 are zero, which they always are with Emacs.
13449 * tparam.h (PC, BC, UP): New extern decls.
13451 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
13452 (xftfont_open): Rename locals to avoid shadowing.

13467 avoid shadowing.
13468 (composition_reseat_it): Remove unused locals.
13469 (find_automatic_composition, composition_adjust_point): Likewise.
13470 (composition_update_it): Mark var as initialized.

13476 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
13477 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
13478 (BUF_DEC_POS): Be more systematic about renaming local temporaries
13479 to avoid shadowing.
13481 * textprop.c (property_change_between_p): Remove; unused.
13483 * intervals.c (interval_start_pos): Now static.

13491 Fix pointer signedness.
13492 (alsa_choose_format): Remove unused local var.
13493 (wav_play): Initialize a variable to 0, to prevent undefined
13494 behavior (Bug#8278).
13496 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
13498 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
13500 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
13501 clobbering (Bug#8298).
13502 * sysdep.c (sys_subshell): Likewise.
13503 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
13505 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
13506 This should get cleaned up, so that child_setup has the
13507 same signature on all platforms.
13509 * callproc.c (call_process_cleanup): Now static.
13510 (relocate_fd): Rename locals to avoid shadowing.
13512 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
13514 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
13515 not to be necessary, and produces flickering.
13517 2011-03-20 Glenn Morris <rgm@gnu.org>
13519 * config.in: Remove file.
13521 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

13540 * makefile.w32-in: Update dependencies.
13542 2011-03-17 Eli Zaretskii <eliz@gnu.org>
13544 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

13566 Define only if needed.
13568 * unexelf.c (unexec): Name an expression,
13569 to avoid gcc -Wbad-function-cast warning.
13570 Use a different way to cause a compilation error if anyone uses
13571 n rather than nn, a way that does not involve shadowing.
13572 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
13574 * deps.mk (unexalpha.o): Remove; unused.

13665 they're used.
13666 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if

13680 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
13681 to use the following functions instead of these macros.
13682 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
13683 EMACS_INT, since callers assume the returned value fits in int.
13684 (upcase1): Likewise, for UPCASE_TABLE.
13685 (uppercasep, lowercasep, upcase): New static inline functions.
13686 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
13687 the race-condition problem in the old DOWNCASE.
13689 * regex.c (CHARSET_LOOKUP_RANGE_TABLE_RAW, POP_FAILURE_REG_OR_COUNT):
13690 Rename locals to avoid shadowing.
13691 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
13692 (regex_compile, re_search_2, re_match_2_internal):
13693 Remove unused local vars.
13694 (FREE_VAR): Rewrite so as not to use empty "else",
13695 which gcc can warn about.
13696 (regex_compile, re_match_2_internal): Mark locals as initialized.
13697 (RETALLOC_IF): Define only if needed.
13698 (WORDCHAR_P): Likewise. This one is never needed, but is used
13699 only in a comment talking about a compiler bug, so put inside
13700 the #if 0 of that comment.
13701 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
13702 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
13703 Remove; unused.
13705 * search.c (boyer_moore): Rename locals to avoid shadowing.
13706 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
13707 (PREV_CHAR_BOUNDARY): Likewise.
13709 * search.c (simple_search): Remove unused var.
13711 * dired.c (compile_pattern): Move decl from here ...
13712 * lisp.h: ... to here, so that it can be checked.
13713 (struct re_registers): New forward decl.
13715 * character.h (INC_POS, DEC_POS): Rename locals to avoid shadowing.
13717 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
13718 All uses changed.
13719 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
13720 Rename locals to avoid shadowing.
13721 (Fvertical_motion): Mark locals as initialized.
13723 * casefiddle.c (casify_object, casify_region): Now static.
13724 (casify_region): Mark local as initialized.
13726 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
13728 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
13729 New macros, so that the caller can use some names other than
13730 gcpro1, gcpro2, etc.
13731 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
13732 of the new macros.
13733 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
13734 argument, for consistency with GCPRO2_VAR, etc: it is now the
13735 prefix of the variable, not the variable itself. All uses
13736 changed.
13737 * dired.c (directory_files_internal, file_name_completion):
13738 Rename locals to avoid shadowing.
13740 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
13741 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
13742 dired.c's scmp function, had undefined behavior.
13743 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
13744 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
13745 * buffer.h: ... to here, because these macros use current_buffer,
13746 and the new implementation with inline functions needs to have
13747 current_buffer in scope now, rather than later when the macros
13748 are used.
13749 (downcase, upcase1): New static inline functions.
13750 (DOWNCASE, UPCASE1): Reimplement using these functions.
13751 This avoids undefined behavior in expressions like
13752 DOWNCASE (x) == DOWNCASE (y), which previously suffered
13753 from race conditions in accessing the global variables
13754 case_temp1 and case_temp2.
13755 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
13756 * lisp.h (case_temp1, case_temp2): Remove their decls.
13757 * character.h (ASCII_CHAR_P): Move from here ...
13758 * lisp.h: ... to here, so that the inline functions mentioned
13759 above can use them.
13761 * dired.c (directory_files_internal_unwind): Now static.
13763 * fileio.c (file_name_as_directory, directory_file_name):
13764 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
13765 Now static.
13766 (file_name_as_directory): Use const pointers when appropriate.
13767 (Fexpand_file_name): Likewise. In particular, newdir might
13768 point at constant storage, so make it a const pointer.
13769 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
13770 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
13771 signedness issues.
13772 (Fset_file_times, Finsert_file_contents, auto_save_error):
13773 Rename locals to avoid shadowing.
13775 * minibuf.c (choose_minibuf_frame_1): Now static.
13776 (Ftry_completion, Fall_completions): Rename or remove locals
13777 to avoid shadowing.
13779 * marker.c (bytepos_to_charpos): Remove; unused.
13781 * lisp.h (verify_bytepos, count_markers): New decls,
13782 so that gcc does not warn that these functions aren't declared.
13784 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
13785 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
13786 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
13787 (copy_text): Remove unused local var.
13789 * filelock.c (within_one_second): Now static.
13790 (lock_file_1): Rename local to avoid shadowing.
13792 * buffer.c (fix_overlays_before): Mark locals as initialized.
13793 (fix_start_end_in_overlays): Likewise. This function should be
13794 simplified by using pointers-to-pointers, but that's a different
13795 matter.
13796 (switch_to_buffer_1): Now static.
13797 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
13798 (report_overlay_modification): Rename locals to avoid shadowing.
13800 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
13801 Fix pointer signedness issue.
13802 (sys_subshell): Mark local as volatile if checking for lint,
13803 to suppress a gcc -Wclobbered warning that does not seem to be right.
13804 (MAXPATHLEN): Define only if needed.
13806 * process.c (serial_open, serial_configure): Move decls from here ...
13807 * systty.h: ... to here, so that they can be checked.
13809 * fns.c (get_random, seed_random): Move extern decls from here ...
13810 * lisp.h: ... to here, so that they can be checked.
13812 * sysdep.c (reset_io): Now static.
13813 (wait_for_termination_signal): Remove; unused.
13815 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
13816 (copy_keymap_item, append_key, push_text_char_description):
13817 Now static.
13818 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
13819 (DENSE_TABLE_SIZE): Remove; unused.
13820 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
13821 (describe_map_tree):

13841 * emacs.c (init_cmdargs): Rename local to avoid shadowing.
13842 (DEFINE_DUMMY_FUNCTION): New macro.
13843 (__do_global_ctors, __do_global_ctors_aux, __do_global_dtors, __main):
13844 Use it.

13846 if GCC considers string literals to be constants.
13848 * lisp.h (fatal_error_signal): Add decl, since it's exported.

13851 (xd_signature, xd_append_arg, xd_initialize):
13852 (Fdbus_call_method, Fdbus_call_method_asynchronously):
13853 (Fdbus_method_return_internal, Fdbus_method_error_internal):

13972 1152921504606846976) returns the obviously-bogus value (-948597
13973 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
13974 reports time overflow. See
