78 * alloc.c (listn): Fix the order the arguments are consed onto the
81 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
82 enumeration constants, as PURE and HEAP are too general, and clash
83 with other headers and sources, such as gmalloc.c and the
84 MS-Windows system headers. All users changed.
86 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>

101 Improve GDB symbol export (Bug#12036).
102 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
103 arms of an 'if', not using conditional expressions; otherwise GDB
104 complains about the types in the unevaluated arm when the argument
105 is an integer literal.
106 (xgetint): Simplify expression.
107 * alloc.c (gdb_make_enums_visible): New constant. This ports to
108 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
109 Zaretskii in <http://bugs.gnu.org/12036#13>.
110 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
111 needed now that we have gdb_make_enums_visible.

156 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
157 emacs.c, as this is a more-suitable home. Had this been done earlier
158 the fix for 12036 would have avoided some of the problems noted in
159 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
160 would have been more obvious.
161 * emacs.c: Do not include <verify.h>; no longer needed.
162 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
163 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
164 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

170 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
171 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
172 not be usable in #if. This simplifies things.
174 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
176 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
178 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

181 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
182 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
183 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
184 Adjust to changes in lisp.h and emacs.c, by using
185 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
186 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
187 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
188 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
189 instead of gdb_valbits.
190 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
191 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
192 instead of gdb_array_mark_flag.
193 (xboolvector): Get size from $->size, not $->header.size.
194 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
195 (xreload, hook-run, hookpost-run): Remove.
196 * emacs.c: Include <verify.h>.
197 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
198 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
200 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
201 (gdb_USE_LSB_TAG): New enum constants.
202 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

205 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
206 as constants, so they're visible to GDB.
207 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
208 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
209 Now enum constants, not macros, so they're visible to GDB.
210 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
211 more convenient now. All uses changed.
212 (VALMASK) [USE_LSB_TAG]: Also define in this case.
213 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.

220 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
222 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
223 add argument, tune behavior, and adjust all callers.
225 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
227 Use typedef for EMACS_INT, EMACS_UINT.
228 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
229 than macros. This simplifies debugging in the usual case, since
230 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
231 and it allows expressions involving EMACS_INT casts.
232 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
234 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>
236 * nsterm.m (ns_read_socket): Return early if there is a modal

246 Adjust buffer text indirection counters at the end of Fkill_buffer.
247 * buffer.c (Fkill_buffer): Adjust indirection counters when the
248 buffer is definitely dead. This should really fix an issue reported
249 by Christoph Scholtes again. (Bug#12007).
250 (init_buffer_once): Initialize indirection counters of
251 buffer_defaults and buffer_local_symbols (for sanity and safety).
253 2012-07-24 Eli Zaretskii <eliz@gnu.org>
255 * xdisp.c (init_iterator): Don't compute dimensions of truncation
256 and continuation glyphs on tooltip frames, leave them at zero.
257 Avoids continued lines in tooltips. (Bug#11832)
259 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
261 Simplify copy_overlay.
262 * buffer.c (copy_overlay): Simplify. Use build_marker.

268 or invalid. (Bug#12025)
270 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
271 it signals an error when a tooltip frame is being created.
273 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>

284 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
286 Swap buffer text indirection counters in Fbuffer_swap_text.
287 * buffer.c (Fbuffer_swap_text): Swap indirections too.
288 This avoids crash reported by Christoph Scholtes at
289 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
291 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
293 * nsmenu.m (Popdown_data): New struct.
294 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
296 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
297 (initWithContentRect): Make imgView and contentView non-static
298 and autorelease them. Also autorelease img and matrix (Bug#12005).
299 (dealloc): Remove (Bug#12005).

316 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
318 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
319 as it's limited by the amount of memory, not by INT_MAX.
321 2012-07-21 Eli Zaretskii <eliz@gnu.org>
323 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
324 in special-event-map. See the discussion at

351 (Fkill_buffer): Adjust indirection counters as needed, don't walk
352 through buffer list if indirection counter is 0.

384 of type Lisp_Object to avoid redundant calls to make_unibyte_string.
385 Adjust users accordingly.
386 * font.h (font_open_by_name): Adjust prototype.

404 * buffer.h (FOR_EACH_BUFFER): Rename from 'for_each_buffer'.
405 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
406 'for_each_per_buffer_object_at'.
407 All uses changed. It's better to use upper-case for macros that
408 cannot be implemented as functions, to give the reader a clue
409 that they're special.
411 2012-07-19 Stefan Monnier <monnier@iro.umontreal.ca>
413 * alloc.c (Fgarbage_collect): Tweak docstring.

459 2012-07-18 Paul Eggert <eggert@cs.ucla.edu>
461 * alloc.c (Fmake_bool_vector): Fix off-by-8 bug

975 2012-07-11 Glenn Morris <rgm@gnu.org>
977 * s/bsd-common.h, s/cygwin.h: No need to undefine INTERRUPT_INPUT,
978 since nothing has defined it on these platforms.
980 * s/aix4-2.h, s/bsd-common.h, s/cygwin.h, s/gnu-linux.h:
981 * s/irix6-5.h: Move SIGNALS_VIA_CHARACTERS to configure.

992 2012-07-11 John Wiegley <johnw@newartisans.com>
994 * alloc.c (mark_memory): Guard the "no_address_safety_analysis"
995 function attribute, so we only use it if it exists in the

1047 * s/aix4-2.h (unix): Remove; no longer needed.
1049 EMACS_TIME simplification (Bug#11875).
1050 This replaces macros (which typically do not work in GDB)
1051 with functions, typedefs and enums, making the code easier to debug.
1052 The functional style also makes code easier to read and maintain.
1053 * systime.h: Include <sys/time.h> on all hosts, not just if
1054 WINDOWSNT, since 'struct timeval' is needed in general.
1055 (EMACS_TIME): Now a typedef, not a macro.
1056 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
1058 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)

1062 (EMACS_SET_SECS, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS)
1063 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
1064 which are not functions. All uses rewritten to use:
1065 (make_emacs_time): New function.
1066 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
1067 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
1068 not functions. All uses rewritten to use the following, respectively:
1069 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
1070 (add_emacs_time, sub_emacs_time): New functions.
1071 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
1072 * fileio.c (Fcopy_file):
1073 * xterm.c (XTflash): Get the current time closer to when it's used.
1074 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

1082 * gtkutil.c (get_utf8_string):
1084 * nsmenu.m (ns_update_menubar):
1085 * regex.c (regerror):
1086 Prefer memcpy to strncpy and strncat when either will do.

1088 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
1089 (menu_separator_name_p):
1090 * nsmenu.m (ns_update_menubar):
1091 Prefer memcmp to strncmp when either will do.
1092 * nsterm.m: Include <ftoastr.h>.
1094 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
1095 Prefer snprintf to strncpy.
1096 * nsterm.m (ns_term_init):
1097 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
1098 * nsterm.m (ns_term_init):
1099 Avoid the need for strncpy, by using build_string or
1100 make_unibyte_string directly. Use dtoastr, not snprintf.
1101 * process.c (Fmake_network_process): Diagnose service names that
1102 are too long, rather than silently truncating them or creating
1103 non-null-terminated names.
1104 (Fnetwork_interface_info): Likewise, for interface names.
1105 * sysdep.c (system_process_attributes) [GNU_LINUX]:
1106 Prefer sprintf to strncat.
1107 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
1108 Prefer vsnprintf to vsprintf + strncpy.
1110 2012-07-10 Glenn Morris <rgm@gnu.org>
1112 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
1113 Clarify fallback case.
1115 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
1117 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
1118 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
1119 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
1120 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
1121 where argument type is known to be a Lisp_Cons.
1123 2012-07-10 Tom Tromey <tromey@redhat.com>
1125 * bytecode.c (BYTE_CODE_THREADED): New macro.
1126 (BYTE_CODES): New macro. Replaces all old byte-code defines.

1131 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
1133 Optimize pure C strings initialization.
1134 * lisp.h (make_pure_string): Fix prototype.
1135 (build_pure_c_string): New function, defined as static inline. This
1136 provides a better opportunity to optimize away calls to strlen when
1137 the function is called with compile-time constant argument.
1138 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
1139 argument, adjust users accordingly. Use build_pure_c_string where
1141 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
1142 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
1143 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
1145 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
1147 Avoid calls to strlen in miscellaneous functions.
1148 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
1149 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
1150 * lread.c (openp): Likewise.
1152 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
1154 Avoid calls to strlen in path processing functions.
1155 * fileio.c (file_name_as_directory): Add comment. Change to add
1156 srclen argument and return the length of result. Adjust users
1158 (directory_file_name): Fix comment. Change to add srclen argument,
1159 swap 1st and 2nd arguments to obey the common convention. Adjust
1161 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
1163 2012-07-10 Glenn Morris <rgm@gnu.org>
1165 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
1166 Move PENDING_OUTPUT_COUNT definition to configure.
1168 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
1169 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
1170 * s/gnu.h (DATA_START): Move definitions to configure.
1172 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
1173 We include usg5-4-common.h, which defines them both.
1175 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
1176 O_RDONLY already includes it).
1178 Stop ns builds setting the EMACSLOADPATH environment variable.
1179 * nsterm.m (ns_load_path): Rename from ns_init_paths.
1180 Now it does not set EMACSLOADPATH, just returns the load-path string.
1181 * nsterm.h: Update accordingly.
1182 * lread.c [HAVE_NS]: Include nsterm.h.
1183 (init_lread) [HAVE_NS]: Use ns_load_path.
1184 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
1186 2012-07-09 Glenn Morris <rgm@gnu.org>
1188 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
1189 since the included bsd-common.h does so.
1191 Stop ns builds setting the EMACSPATH environment variable.
1192 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
1193 (ns_init_paths): Do not set EMACSPATH.
1194 * nsterm.h (ns_exec_path): Add it.
1195 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
1198 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
1200 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
1202 * process.c (wait_reading_process_output): 'waitchannels' was unset
1203 when read_kbd || !NILP (wait_for_cell); fix this.
1205 Add GCC-style 'const' attribute to functions that can use it.
1206 * character.h (char_resolve_modifier_mask):
1207 * keyboard.h (make_ctrl_char):
1208 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
1209 (init_character_once, next_almost_prime, init_fns, init_image)
1210 (flush_pending_output, init_sound):
1211 * mem-limits.h (start_of_data):

1215 Declare the dummy function with ATTRIBUTE_CONST.
1216 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
1217 Add decls with ATTRIBUTE_CONST.
1219 Minor improvements to make_formatted_string.
1220 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
1221 where int is good enough, as vsprintf returns an int.
1222 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
1224 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
1226 Use make_formatted_string to avoid double length calculation.
1227 * lisp.h (make_formatted_string): New prototype.
1228 * alloc.c (make_formatted_string): New function.
1229 * buffer.c (Fgenerate_new_buffer_name): Use it.
1230 * dbus.c (syms_of_dbusbind): Likewise.
1231 * editfns.c (Fcurrent_time_zone): Likewise.
1232 * filelock.c (get_boot_time): Likewise.
1233 * frame.c (make_terminal_frame, set_term_frame_name)
1234 (x_report_frame_params): Likewise.
1235 * image.c (gs_load): Likewise.
1236 * minibuf.c (get_minibuffer): Likewise.
1237 * msdos.c (dos_set_window_size): Likewise.
1238 * process.c (make_process): Likewise.

1251 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
1253 Move marker debugging code under MARKER_DEBUG.
1254 * marker.c (MARKER_DEBUG): Move marker debugging code under
1255 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
1256 for bootstrap with --enable-checking (~3x slowdown reported
1257 by Juanma Barranquero <lekktu@gmail.com>).
1258 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
1260 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
1262 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
1263 See <http://bugs.gnu.org/11825#29>.
1265 2012-07-08 Eli Zaretskii <eliz@gnu.org>
1267 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
1268 has no font, use the frame's font. (Bug#11813)
1269 (display_line): Add commentary about displaying truncation glyphs
1271 (produce_special_glyphs): Move here from term.c.
1273 * term.c (produce_special_glyphs): Move to xdisp.c.
1275 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
1278 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
1280 * xdisp.c (display_line): Avoid warning about implicit declaration
1283 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
1285 * lisp.h: Remove empty conditional.
1287 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
1289 * lread.c (load_path_check): Now static.
1291 Fix some minor --with-ns problems found by static checking.
1292 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
1293 (x_set_font) [!HAVE_X_WINDOWS]:
1294 * image.c (xpm_load_image) [HAVE_NS]:
1295 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
1296 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
1297 Remove unused local.
1298 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
1299 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
1300 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
1301 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
1302 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
1303 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
1304 Fix pointer signedness problem.
1305 * xfaces.c (FRAME_X_FONT_TABLE):
1306 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
1308 2012-07-07 Glenn Morris <rgm@gnu.org>
1310 * lread.c (load_path_check): New function, split from init_lread.
1311 (init_lread): Reorganize. Motivation:
1312 If EMACSLOADPATH is set, check/warn about that rather than the
1313 defaults, which we are not going to use. Hence we can remove
1314 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
1315 Don't warn if site-lisp directories are missing.
1316 If not installed, start from a blank load-path, since
1317 PATH_LOADSEARCH refers to the eventual installation directories.
1319 2012-07-07 Eli Zaretskii <eliz@gnu.org>
1321 Support truncation and continuation glyphs on GUI frames, when
1322 fringes are disabled. (Bug#11832)
1323 * xdisp.c (init_iterator): Get dimensions of truncation and
1324 continuation glyphs even if on GUI frames. Adjust
1325 it->last_visible_x on GUI frames when the left or right fringes,
1326 or both, are absent.
1327 (start_display, move_it_in_display_line_to): Handle the case of a
1328 GUI frame without a fringe to display continuation or truncation
1330 (insert_left_trunc_glyphs): Support GUI frames: make sure
1331 truncation glyphs overwrite enough glyphs from the current line to
1332 have sufficient space in pixels.
1333 (display_line): Support truncation and continuation glyphs on GUI
1334 frames. If some spare pixels are left on the line after inserting
1335 the truncation glyphs, fill that space with a stretch glyph of a
1336 suitably computed width.
1338 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
1339 produce_glyphs, to support GUI sessions.
1341 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
1343 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
1345 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
1347 Do not require float-time's arg to fit in time_t (Bug#11825).
1348 This works better on hosts where time_t is unsigned, and where
1349 float-time is applied to the (negative) difference between two times.
1350 * editfns.c (decode_time_components): Last arg is now double *,
1351 not int *, and means to store all the result as a double, without
1352 worrying about whether the seconds part fits in time_t.
1353 All callers changed.
1354 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
1355 All callers changed.
1356 (Ffloat_time): Do not fail merely because the specified time falls
1357 outside of time_t range.
1359 2012-07-07 Glenn Morris <rgm@gnu.org>
1361 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
1362 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
1363 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
1365 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
1367 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
1368 Update dependencies.
1370 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
1372 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1374 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
1375 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
1376 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
1377 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
1378 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
1379 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
1381 * xfont.c (compare_font_names): Redo to omit the need for casts.
1383 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
1385 * xfns.c (Fx_change_window_property): Doc fix.
1386 * w32fns.c (Fx_change_window_property): Doc fix.
1388 * w32fns.c (Fx_window_property): Accept the same arguments as the
1389 X Windows version. Doc fix.
1390 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
1392 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
1393 Eli Zaretskii <eliz@gnu.org>
1395 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.

1397 Obsolete settings removed.
1399 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1401 * process.c: Avoid unnecessary calls to gettime.
1402 (wait_reading_process_output): Don't get the time of day
1403 when gobbling data immediately and not waiting, as there's no need
1404 for it in that case. This removes a FIXME.
1406 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
1408 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
1409 is defined (Bug#11768).

1413 Fix marker debugging code.
1414 * marker.c (byte_char_debug_check): Do not perform the check
1415 if buffer is not multibyte.
1416 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
1417 Call byte_char_debug_check with correct arguments.
1419 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1421 Compile marker debugging code only if ENABLE_CHECKING is defined.
1422 * marker.c (byte_char_debug_check, count_markers):
1423 Use only if ENABLE_CHECKING is defined.
1424 (byte_debug_flag): Remove.
1425 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
1426 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
1428 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1430 Avoid code repetition in marker-related functions.
1431 * marker.c (attach_marker): New function.

1434 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
1435 Consistently rename charno to charpos.
1436 (marker_position): Add eassert.
1437 (marker_byte_position): Convert to eassert.
1439 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

1449 * lisp.h (build_marker): New prototype.
1450 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
1451 * composite.c (autocmp_chars): Likewise.
1452 * editfns.c (buildmark): Remove.
1453 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
1454 (save_restriction_save): Use build_marker.
1455 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
1456 * window.c (save_window_save): Likewise.
1458 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1460 Do not use Fdelete_overlay in delete_all_overlays
1461 to avoid redundant calls to unchain_overlay.
1462 * buffer.c (drop_overlay): New function.
1463 (delete_all_overlays, Fdelete_overlay): Use it.
1464 * minibuf.c (get_minibuffer): Fix comment.
1466 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1468 Port to OpenBSD 5.1 amd64.
1469 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
1470 This is needed for OpenBSD, and should be harmless on all BSD systems.
1471 Also, include <sys/sysctl.h>, as it should be available on all
1472 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
1473 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
1474 use p_pid member, not kp_proc.pid.
1476 2012-07-06 Glenn Morris <rgm@gnu.org>
1478 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
1480 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
1482 More xmalloc and related cleanup.
1483 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:

1491 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
1493 Omit needless casts involving void * pointers and allocation.
1494 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
1495 as the former is more robust if P's type is changed.
1496 Prefer xzalloc to xmalloc + memset 0.
1497 Simplify malloc-or-realloc to realloc.
1498 Don't worry about xmalloc returning a null pointer.
1499 Prefer xstrdup to xmalloc + strcpy.
1500 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
1502 * keyboard.c (apply_modifiers_uncached): Prefer local array to
1503 alloca of a constant.
1505 2012-07-05 Eli Zaretskii <eliz@gnu.org>
1507 * xdisp.c (display_line): Fix horizontal pixel coordinates when
1508 hscroll is larger than the line width. Fixes long and futile
1509 looping inside extend_face_to_end_of_line (on a TTY) producing
1510 glyphs that are not needed and thrown away.
1512 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
1514 * marker.c (set_marker_restricted_both): Simplify by using
1517 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>

1524 not defined (Bug#11768).
1525 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
1526 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
1527 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
1528 followed by gtk_box_set_homogeneous (Bug#11768).
1529 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
1530 (update_theme_scrollbar_width, xg_create_scroll_bar):
1531 Use gtk_scrollbar_new (Bug#11768).
1532 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
1533 (is_box_type): New function (Bug#11768).
1534 (xg_tool_item_stale_p): Call is_box_type.
1535 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
1536 with default display (Bug#11768).

1540 * xdisp.c (window_hscroll_limited): New function.
1541 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
1542 coordinates when window's hscroll is set to insanely large
1545 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
1547 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

1606 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
1608 * fileio.c (time_error_value): Check the right error number.
1609 Problem reported by Troels Nielsen in
1610 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
1612 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1614 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
1615 This should be fixed in a better way; see Eli Zaretskii in
1616 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
1617 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
1619 * fileio.c (time_error_value): Rename from special_mtime.
1620 The old name's problems were noted by Eli Zaretskii in
1621 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
1623 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
1624 This variable's comment says Emacs needs at least one GDB-visible
1625 symbol of type enum pvec_type, to work around GDB problems.
1626 The symbol's value doesn't matter.
1628 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
1629 that causes compilation to fail on pre-C99 compilers.
1631 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
1633 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
1634 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
1636 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
1638 * buffer.c (init_buffer_once): Fix initialization of
1639 headers for buffer_defaults and buffer_local_symbols.
1640 Reported by Juanma Barranquero <lekktu@gmail.com>.
1642 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
1644 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
1645 * lisp.h (enum pvec_type): Use fewer bits.
1646 (PSEUDOVECTOR_SIZE_BITS): New constant.
1647 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
1648 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
1649 change in pvec_type.
1650 (PSEUDOVECTOR_TYPEP): New macro.
1651 (TYPED_PSEUDOVECTORP): Use it.
1652 * fns.c (internal_equal): Adapt code to extract pvectype.

1654 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
1655 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
1656 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
1657 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
1658 (sweep_vectors): Use it. Use local var `total_bytes' instead of
1659 abusing vector->header.next.nbytes.
1660 (live_vector_p): Use PVEC_TYPE.
1661 (mark_object): Adapt code to extract pvectype. Use switch.
1663 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1665 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
1666 Tighten new eassert a bit.
1668 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
1670 Fix compilation with --enable-gcc-warnings and -O1
1672 * doprnt.c (doprnt): Change type of tem to int, initialize
1673 to avoid compiler warning. Add eassert.
1674 * search.c (simple_search): Initialize match_byte to avoid
1675 compiler warning. Add eassert.
1677 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1679 Avoid weird behavior with large horizontal scrolls.
1680 Without this change, for example, large hscroll values would
1681 mess up Emacs's display on Fedora 15 x86, presumably due to
1682 overflows in int calculations in the display code.
1683 Also, if buffers had long lines, Emacs would freeze.
1684 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
1685 (set_window_hscroll): New function, containing the old guts of
1686 Fset_window_hscroll. Return the clipped value.
1687 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
1688 This avoids the need to check against PTRDIFF_MAX.
1690 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
1692 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
1694 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
1696 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1698 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
1699 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
1700 since GCC 4.4.6 issues a bogus warning for them.
1702 Fix bugs in file timestamp newness comparisons.
1703 * fileio.c (Ffile_newer_than_file_p):
1704 * lread.c (Fload): Use full timestamp resolution of files,
1705 not just the 1-second resolution, so that files that are only
1706 slightly newer still count as newer.
1707 * fileio.c (Ffile_newer_than_file_p): Don't assume file
1708 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
1710 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
1712 * fileio.c: Improve handling of file time marker. (Bug#11852)
1713 (special_mtime): New function.
1714 (Finsert_file_contents, Fverify_visited_file_modtime):
1715 Use it to set special mtime values consistently.
1717 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
1719 * fileio.c (Finsert_file_contents): Properly handle st_mtime
1720 marker for non-existing file. (Bug#11852)
1722 2012-07-03 Glenn Morris <rgm@gnu.org>
1724 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
1725 and did not make it into globals.h).
1727 2012-07-03 Tom Tromey <tromey@redhat.com>
1729 * window.c (Fset_window_margins, Fset_window_fringes)

1763 * xterm.h: Remove EXFUN.
1765 2012-07-03 Glenn Morris <rgm@gnu.org>
1767 * lisp.h (Frandom): Make it visible to C.
1768 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
1769 buffer for invisible buffers. (Bug#1229)
1771 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
1773 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
1774 values which aren't power of 2.
1775 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro. Verify
1776 it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
1779 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
1781 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
1783 * alloc.c (mark_object): Revert part of last patch to use `switch'.
1785 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
1787 * alloc.c (allocate_vector_block): Remove redundant
1788 calls to mallopt if DOUG_LEA_MALLOC is defined.
1789 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
1790 avoid calls to mallopt if zero_vector is returned.
1792 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
1794 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
1795 is enabled, avoid dereferencing NULL current_sblock if
1798 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
1800 Cleanup basic buffer management.
1801 * buffer.h (struct buffer): Change layout to use generic vector
1802 marking code. Fix some comments. Change type of 'clip_changed'
1803 to bitfield. Remove unused #ifndef old.
1804 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
1805 (GET_OVERLAYS_AT): Fix indentation.

1810 * alloc.c (allocate_buffer): Adjust to match new layout of
1811 struct buffer. Fix comment.
1812 (mark_overlay): New function.
1813 (mark_buffer): Use it. Use mark_vectorlike to mark normal
1814 Lisp area of struct buffer.
1815 (mark_object): Use it. Adjust marking of misc objects
1816 and related comments.
1818 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
1820 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
1821 wrapper that is not needed because the wrapped code is a no-op (zero
1822 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
1823 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
1825 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
1827 * alloc.c (mark_buffer): Simplify. Remove prototype.
1828 (mark_object): Add comment. Reorganize marking of vector-like
1829 objects. Use CHECK_LIVE for all vector-like objects except buffers
1830 and subroutines when GC_CHECK_MARKED_OBJECTS is defined. Avoid
1831 redundant calls to mark_vectorlike for bool vectors.
1833 2012-06-30 Glenn Morris <rgm@gnu.org>
1835 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
1837 * epaths.in (PATH_SITELOADSEARCH): New.
1838 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
1839 This is rather than relying on --enable-locallisppath elements
1840 having "site-lisp" in their names. (Bug#10208#25, 11658)
1842 2012-06-30 Eli Zaretskii <eliz@gnu.org>
1844 * w32proc.c (sys_select): Accept and ignore one more argument.
1846 * w32.c (emacs_gnutls_pull): Call select with one more argument.
1848 * sysselect.h [DOS_NT]: Don't include sys/select.h.
1849 (pselect) [!MS_DOS]: Redirect to sys_select.
1851 * sysdep.c: Don't include dos.h and dosfns.h.
1853 * process.c (sys_select):
1854 * msdos.c (sys_select): Accept one more argument and ignore it.
1856 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
1857 adapt data types and code to that.
1860 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
1861 which clashes with the gnulib function of the same name.
1863 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
1865 * font.c (font_style_to_value, font_style_symbolic)

1869 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
1871 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
1874 2012-06-29 Eli Zaretskii <eliz@gnu.org>
1876 * xdisp.c (try_window_id): Undo last change.
1878 * w32.c (getwd): Adjust commentary about startup_dir.
1879 (init_environment): Always call sys_access, even in non-MSVC
1880 builds. Don't chdir to the directory of the Emacs executable.
1881 This undoes code from 1997 which was justified by the need to
1882 "avoid conflicts when removing and renaming directories". But its
1883 downside was that every relative file name was being interpreted
1884 relative to the directory of the Emacs executable, which can never
1885 be TRT. In particular, it broke sys_access when called with
1886 relative file names.
1887 (sys_access): Map GetLastError to errno.
1889 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
1891 * window.h (struct window): Change type of 'fringes_outside_margins'

2071 * alloc.c: Remove build_string.
2072 * lisp.h: Define build_string as static inline. This provides
2073 a better opportunity to optimize away calls to strlen when the
2074 function is called with compile-time constant argument.

2076 * w32proc.c (sys_spawnve): Likewise.

2079 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
2081 Use sprintf return value instead of invoking strlen on result.
2082 In the old days this wasn't portable, since some sprintf
2083 implementations returned char *. But they died out years ago and
2084 Emacs already assumes sprintf returns int.
2085 Similarly for float_to_string.
2086 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

2093 * xfns.c (syms_of_xfns):
2094 Use sprintf or float_to_string result to avoid need to call strlen.
2095 * data.c (Fnumber_to_string):
2096 Use make_unibyte_string, since the string must be ASCII.
2097 * lisp.h, print.c (float_to_string): Now returns int length.
2098 * term.c (produce_glyphless_glyph):
2099 Use sprintf result rather than recomputing it.
2101 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
2102 * Makefile.in (ALL_CFLAGS):
2103 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

2109 strcasecmp if available.

2132 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
2134 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

2137 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
2139 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
2140 instead of truncating it to 63 (admittedly a generous limit).
2142 * process.c: Fix spelling and caps in comments.

2200 * keyboard.c (kbd_buffer_get_event):
2201 * process.c (Faccept_process_output):
2202 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
2203 This improves on the previous patch, which introduced a bug
2204 when time_t is unsigned and as wide as intmax_t.
2205 See <http://bugs.gnu.org/9000#51>.
2207 2012-06-23 Eli Zaretskii <eliz@gnu.org>

2224 Privately reported by Herbert J. Skuhra.
2225 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.

2270 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
2272 Support higher-resolution time stamps (Bug#9000).
2273 The time stamps are only nanosecond-resolution at the C level,
2274 since that's the best that any real-world system supports now.
2275 But they are picosecond-resolution at the Lisp level, as that's
2276 easy, and leaves room for future OS improvements.
2278 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
2281 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
2282 Don't get current time unless it's needed.
2284 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
2285 now provides it if it's absent.
2286 (start_atimer): Port to higher-res time stamps.
2287 Check for time stamp overflow. Don't get current time more
2288 often than is needed.
2290 * buffer.h (struct buffer): Buffer modtime now has high resolution.
2291 Include systime.h, not time.h.
2292 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
2294 * dired.c: Include stat-time.h.
2295 (Ffile-attributes): File times now have higher resolution.
2297 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
2298 (struct image): Timestamp now has higher resolution.
2300 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
2301 has at least microseconds now. All uses removed.
2302 (update_frame, update_single_window, update_window, update_frame_1)
2303 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
2305 * editfns.c (time_overflow): Now extern.
2306 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
2307 (float-time, Fformat_time_string, Fcurrent_time_string)
2308 (Fcurrent_time_zone): Accept and generate higher-resolution
2310 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
2311 (decode_time_components, lisp_seconds_argument): New functions.
2312 (make_time): Now static.
2313 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
2314 Report an error if the time is invalid, rather than having the caller
2317 * fileio.c: Include <stat-time.h>
2318 (Fcopy_file): Copy higher-resolution time stamps.
2319 Prefer to set the time stamp via a file descriptor if that works.
2320 (Fset_file_times, Finsert_file_contents, Fwrite_region)
2321 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
2322 (Fvisited_file_modtime, Fset_visited_file_modtime):
2323 Support higher-resolution time stamps.
2325 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
2327 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
2329 * image.c (prepare_image_for_display, clear_image_cache)
2330 (lookup_image): Port to higer-resolution time stamps.
2332 * keyboard.c (start_polling, bind_polling_period):
2333 Check for time stamp overflow.
2334 (read_char, kbd_buffer_get_event, timer_start_idle)
2335 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
2336 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
2337 Port to higher-resolution time stamps. Do not assume time_t is signed.
2338 (decode_timer): New function. Timers are now vectors of length 9,
2339 not 8, to accommodate the picosecond component.
2340 (timer_check_2): Use it.
2342 * nsterm.m (select_timeout, timeval_subtract): Remove.
2343 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
2344 as they're a bit more accurate and handle overflow better.
2345 (ns_select): Change prototype to be compatible with pselect.
2346 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
2347 * nsterm.h (ns_select): Adjust prototype.
2349 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
2350 us-resolution time stamps.
2351 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
2353 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
2355 * lisp.h (time_overflow): New decl.
2356 (wait_reading_process_output): First arg is now intmax_t, not int,
2357 to accommodate larger waits.
2359 * process.h (struct Lisp_Process.read_output_delay):
2360 Now counts nanoseconds, not microseconds.
2361 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
2363 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
2364 (wait_reading_process_output):
2365 Port to ns-resolution time stamps.
2366 (Faccept_process_output, wait_reading_process_output):
2367 Check for time stamp overflow. Do not assume time_t is signed.
2368 (select_wrapper): Remove; we now use pselect.
2369 (Fprocess_attributes): Now generates ns-resolution time stamps.
2371 * sysdep.c: Include utimens.h. Don't include utime.h
2372 or worry about struct utimbuf; gnulib does that for us now.
2373 (gettimeofday): Remove; gnulib provides a substitute.
2374 (make_timeval): New function.
2375 (set_file_times): Now sets ns-resolution time stamps.
2376 New arg FD; all uses changed.
2377 (time_from_jiffies, ltime_from_jiffies, get_up_time)

2379 Now returns ns-resolution time stamp. All uses changed.
2380 Check for time stamp overflow.
2382 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
2383 provides a substitute now.
2385 * systime.h: Include timespec.h rather than sys/time.h and time.h,
2386 since it guarantees struct timespec.
2387 (EMACS_TIME): Now struct timespec, so that we can support
2388 ns-resolution time stamps.
2389 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.

2391 (EMACS_USECS): Remove.
2392 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
2393 so multiply the arg by 1000 before storing it.
2394 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
2396 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):

2403 (make_timeval, make_lisp_time, decode_time_components): New decls.
2404 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
2405 that it mishandled time_t overflow. You can't compare by subtracting!
2406 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
2407 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
2409 * term.c: Include <sys/time.h>.
2410 (timeval_to_Time): New function, for proper overflow wraparound.

2415 (Fprimitive_undo): Use them when restoring time stamps.
2417 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
2418 (w32_get_internal_run_time):
2419 Port to higher-resolution Emacs time stamps.
2420 (ltime): Now accepts single 64-bit integer, as that's more convenient
2423 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
2425 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
2426 for compatibility with pselect. Support ns-resolution time stamps.
2428 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
2430 * xselect.c (wait_for_property_change, x_get_foreign_selection):
2431 Check for time stamp overflow, and support ns-resolution time stamps.
2433 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
2434 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
2435 (timeval_subtract): Remove; no longer needed.
2436 (XTflash, XTring_bell, x_wait_for_event):
2437 Port to ns-resolution time stamps. Don't assume time_t is signed.

2443 2012-06-22 Eli Zaretskii <eliz@gnu.org>
2445 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
2446 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
2447 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
2448 staticidx goes up to 1597 out of 1600 = 0x640.)
2450 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
2452 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
2453 Otherwise, the umask might be mistakenly 0 while handling input signals.
2455 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
2457 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

2463 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
2464 access to `contents' member of Lisp_Vector objects with AREF and ASET
2467 2012-06-19 Chong Yidong <cyd@gnu.org>
2469 * frame.c (delete_frame): When selecting a frame on a different
2470 text terminal, do not alter the terminal's top-frame.

2474 (unwind_format_mode_line): Restore them.
2475 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
2477 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
2478 since tty frames can be explicitly named.
2479 (prepare_menu_bars): Likewise.
2481 * term.c (Ftty_top_frame): New function.
2483 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
2485 Port byte-code-meter to modern targets.
2486 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
2487 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
2488 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
2489 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
2490 (METER_1, METER_2): Simplify.

2496 2012-06-18 Martin Rudalics <rudalics@gmx.at>
2498 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
2499 gets killed during executing of this function (Bug#11665).
2500 Try to always return Qt when the buffer has been actually killed.
2501 (Vkill_buffer_query_functions): In doc-string say that functions
2502 run by this hook should not change the current buffer.
2504 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
2506 Fix recently-introduced process.c problems found by static checking.
2507 * process.c (write_queue_push, write_queue_pop, send_process):

2526 * lisp.h (eassert): Assume C89 or later.
2527 This removes the need for CHECK.
2528 (CHECK): Remove. Its comments about always evaluating its
2529 argument were confusing, as 'eassert' typically does not evaluate
2532 * coding.c (produce_chars): Use ptrdiff_t, not int.
2534 * xterm.c (x_draw_underwave): Check for integer overflow.
2535 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

2828 2012-06-08 Juanma Barranquero <lekktu@gmail.com>
2830 * dispnew.c (showing_window_margins_p): Wrap in #if 0 to prevent unused
2831 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
2833 2012-06-08 Eli Zaretskii <eliz@gnu.org>
2835 * alloc.c (allocate_vectorlike): Fix last change.
2837 2012-06-08 Dmitry Antipov <dmantipov@yandex.ru>
2839 Block-based vector allocation of small vectors.
2840 * lisp.h (struct vectorlike_header): New field `nbytes',
2841 adjust comment accordingly.
2842 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'
2843 to denote vector blocks. Adjust users (live_vector_p,
2844 mark_maybe_pointer, valid_lisp_object_p) accordingly.
2845 (COMMON_MULTIPLE): Move outside #if USE_LSB_TAG.
2846 (VECTOR_BLOCK_SIZE, vroundup, VECTOR_BLOCK_BYTES),
2847 (VBLOCK_BYTES_MIN, VBLOCK_BYTES_MAX, VECTOR_MAX_FREE_LIST_INDEX),
2848 (VECTOR_FREE_LIST_FLAG, ADVANCE, VINDEX, SETUP_ON_FREE_LIST),
2849 (VECTOR_SIZE, VECTOR_IN_BLOCK): New macros.

2866 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
2868 * doprnt.c (doprnt): Truncate multibyte char correctly.
2869 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
2870 would mishandle a string argument "Xc" if X was a multibyte
2871 character of length 2: it would truncate after X's first byte
2872 rather than including all of X.
2874 2012-06-06 Chong Yidong <cyd@gnu.org>
2876 * buffer.c (word_wrap): Doc fix.

2902 (note_mode_line_or_margin_highlight): If there is no help echo,
2903 use mode-line-default-help-echo. Handle the case where the mouse
2904 position is past the end of the mode line string.
2906 * buffer.c (buffer_local_value_1): New function, split from
2907 Fbuffer_local_value; can return Qunbound.

2923 * minibuf.c (Fassoc_string): Remove duplicate declaration.
2925 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
2926 Convert pctcpu and pctmem to Lisp float properly.
2927 Let the compiler fold better, as 100.0/0x8000 is exact.
2929 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
2931 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
2934 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
2936 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
2938 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
2940 For a 'struct window', replace some Lisp_Object fields to
2941 bitfields where appropriate, remove unused fields.
2942 * window.h (struct window): Remove unused 'last_mark_x' and
2943 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
2944 change it's type from Lisp_Object to bitfield.
2945 Change type of 'force_start', 'optional_new_start',
2946 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
2947 fields from Lisp_Object to bitfield. Adjust users accordingly.
2949 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
2951 Pacify gcc -Wdouble-precision when using Xaw.
2952 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
2953 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
2954 Use 'float' consistently, rather than 'float' in most places
2955 and 'double' in a couple of places.
2957 2012-05-31 Eli Zaretskii <eliz@gnu.org>
2959 * xdisp.c (handle_stop): Detect whether we have overlay strings
2960 loaded by testing it->current.overlay_string_index to be
2961 non-negative, instead of checking whether n_overlay_strings is
2962 positive. (Bug#11587)
2964 2012-05-31 Chong Yidong <cyd@gnu.org>
2966 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
2968 * doc.c (Fsubstitute_command_keys): Doc fix.
2970 2012-05-31 Eli Zaretskii <eliz@gnu.org>
2972 * search.c (search_buffer): Remove calls to
2973 r_alloc_inhibit_buffer_relocation, as it is now called by
2974 maybe_unify_char, which was the cause of relocation of buffer text
2977 2012-05-31 Eli Zaretskii <eliz@gnu.org>
2979 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
2980 for the duration of call to load_charset, to avoid problems with
2981 callers of maybe_unify_char that access buffer text through C
2984 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
2985 decrement the inhibition flag, instead of just setting or
2988 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
2990 Remove obsolete '#define static' cruft.
2991 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
2992 This #undef was "temporary" in 2000; it is no longer needed
2993 now that '#define static' has gone away.
2994 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
2995 (gray_bitmap_bits): Remove; no longer needed.
2996 All uses replaced with definiens.
2997 * xterm.c: Include "bitmaps/gray.xbm".
2999 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
3001 Clean up __executable_start, monstartup when --enable-profiling.
3002 The following changes affect the code only when profiling.
3003 * dispnew.c (__executable_start): Rename from safe_bcopy.
3004 Define only on platforms that need it.
3005 * emacs.c: Include <sys/gmon.h> when profiling.
3006 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
3007 (__executable_start): Remove decl, since lisp.h does it now.
3008 (safe_bcopy): Remove decl; no longer has that name.
3009 (main): Coalesce #if into single bit of code, for simplicity.
3010 Cast pointers to uintptr_t, since standard libraries want integers

3035 * lread.c (read1): Tiny simplification.
3037 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
3039 Do not create empty overlays with the evaporate property (Bug#9642).
3040 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
3041 Bug#9642, but explicitly check that the buffer the overlay would
3042 be moved to is live and rearrange lines to make sure that errors
3043 will not put the overlay in an inconsistent state.
3044 (Fdelete_overlay): Cosmetics.
3046 2012-05-28 Eli Zaretskii <eliz@gnu.org>
3048 * w32term.c (my_bring_window_to_top): New function.
3049 (x_raise_frame): Use handle returned by DeferWindowPos, which
3050 could be different from the original one.

3054 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
3055 by calling BringWindowToTop.
3057 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
3058 (WM_EMACS_END): Increase by one.
3060 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
3062 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
3063 This avoids undefined behavior that might cause the eassert
3064 to not catch an out-of-range value.
3066 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
3068 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

3080 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
3082 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
3083 Only r_alloc_inhibit_buffer_relocation needed to be added;
3084 the others were already declared.
3086 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
3087 before checking whether it's out of range. Put the check inside
3089 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
3091 2012-05-27 Ken Brown <kbrown@cornell.edu>
3093 * callproc.c (Fcall_process): Restore a line that was accidentally
3094 commented out in the 2011-02-13 change (bug#11547).

3098 * lisp.h [REL_ALLOC]: Add prototypes for external functions
3099 defined on ralloc.c.
3101 * buffer.c [REL_ALLOC]: Remove prototypes of
3102 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
3103 they are now on lisp.h.
3105 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
3107 * search.c (search_buffer): Use it to inhibit relocation of buffer
3108 text while re_search_2 is doing its job, because re_search_2 is
3109 passed C pointers to buffer text. (Bug#11519)
3111 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
3114 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
3115 state after an additional call to move_it_in_display_line_to, keep
3116 the values of it->max_ascent and it->max_descent found for the
3118 (pos_visible_p): Revert the comparison against bottom_y to what it
3119 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
3122 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3124 Fix coding-related core dumps with gcc -ftrapv.
3125 The code was computing A - B, where A and B are pointers, and B is
3126 random garbage. This can lead to core dumps on platforms that
3127 have special pointer registers, and it also leads to core dumps on
3128 x86-64 when compiled with gcc -ftrapv. The fix is to compute
3129 A - B only when B is initialized properly.
3130 * coding.c (coding_set_source, coding_set_destination): Return void.
3131 (coding_change_source, coding_change_destinations): New functions,
3132 with the old behaviors of coding_set_source and coding_set_destination.
3133 All callers that need an offset changed to use these new functions.
3135 2012-05-26 Glenn Morris <rgm@gnu.org>
3137 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
3139 2012-05-26 Eli Zaretskii <eliz@gnu.org>
3141 Extend mouse support on W32 text-mode console.
3142 * xdisp.c (draw_row_with_mouse_face):
3143 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
3145 * w32console.c: Include window.h.
3146 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
3148 (initialize_w32_display): Initialize mouse-highlight data.
3150 * w32inevt.c: Include termchar.h and window.h.
3151 (do_mouse_event): Support mouse-autoselect-window. When the mouse
3152 moves, call note_mouse_highlight. If help_echo changed, call
3153 gen_help_event to produce help-echo message in the echo area.
3154 Call clear_mouse_face if mouse_face_hidden is set in the mouse
3157 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3159 * lread.c (read1): Simplify slightly to avoid an overflow warning
3160 with GCC 4.7.0 on x86-64.
3162 2012-05-26 Eli Zaretskii <eliz@gnu.org>
3164 * bidi.c (bidi_mirror_char): Revert last change: an int is
3165 definitely wide enough here.
3167 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
3169 Fix integer width and related bugs (Bug#9874).

3179 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3180 (allocate_pseudovector):
3181 Use int, not EMACS_INT, where int is wide enough.
3182 (inhibit_garbage_collection, Fgarbage_collect):
3183 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

3185 int might not be wide enough.
3186 (bidi_cache_search, bidi_cache_find, bidi_init_it)

3190 (bidi_level_of_next_char, bidi_move_to_visually_next):
3191 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3192 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)

3195 (Fset_buffer_multibyte, overlays_at, overlays_in)
3196 (overlay_touches_p, struct sortvec, record_overlay_string)
3197 (overlay_strings, recenter_overlay_lists)
3198 (adjust_overlays_for_insert, adjust_overlays_for_delete)
3199 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
3200 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
3201 (Foverlay_recenter, last_overlay_modification_hooks_used)
3202 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
3203 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3204 (validate_region): Omit unnecessary test for b <= e,
3205 since that's guaranteed by the previous test.
3206 (adjust_overlays_for_delete): Avoid pos + length overflow.
3207 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
3208 (report_overlay_modification):
3209 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3210 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
3211 Omit pointer cast, which isn't needed anyway, and doesn't work
3212 after the EMACS_INT -> ptrdiff_t change.
3213 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
3214 * buffer.h: Adjust decls to match defn changes elsewhere.
3215 (struct buffer_text, struct buffer):
3216 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3217 Use EMACS_INT, not int, where int might not be wide enough.
3218 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
3219 not int, to avoid needless 32-bit limit on 64-bit hosts.
3220 (exec_byte_code): Use tighter memory-full test, one that checks
3221 for alloca overflow. Don't compute the address of the object just
3222 before an array, as that's not portable. Use EMACS_INT, not
3223 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
3224 * callint.c (Fcall_interactively):
3225 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3226 * callproc.c (call_process_kill, Fcall_process):
3227 Don't assume pid_t fits into an Emacs fixnum.
3228 (call_process_cleanup, Fcall_process, child_setup):
3229 Don't assume pid_t fits into int.
3230 (call_process_cleanup, Fcall_process, delete_temp_file)

3235 * casefiddle.c (casify_object, casify_region, operate_on_word)
3236 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
3237 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3238 (casify_object): Avoid integer overflow when overallocating buffer.
3239 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
3240 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
3241 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
3242 * category.h (CATEGORYP): Don't assume arg is nonnegative.
3243 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
3244 integers are now checked earlier. All uses replaced with XINT.
3246 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3247 For CCL_MapSingle, check that content and value are in int range.

3249 Check that Vcode_version_map_vector is a vector.
3250 (resolve_symbol_ccl_program): Check that vector header is in range.
3251 Always copy the vector, so that we can check its contents reliably
3252 now rather than having to recheck each instruction as it's being
3253 executed. Check that vector words fit in 'int'.
3254 (ccl_get_compiled_code, Fregister_ccl_program)
3255 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
3256 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
3257 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
3258 contents are in range.
3259 (Fccl_execute_on_string): Check that status is in range.
3260 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
3261 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
3262 Accept and return EMACS_INT, not int, because callers can pass values

3269 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

3271 avoid mishandling large integers.

3303 Don't assume fixnum fits in int.

3962 (x_connection_closed):
3963 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3964 * xterm.h: Adjust decls to match defn changes elsewhere.
3965 (struct scroll_bar): Use struct vectorlike_header
3966 rather than rolling our own approximation.
3967 (SCROLL_BAR_VEC_SIZE): Remove; not used.
3969 2012-05-25 Glenn Morris <rgm@gnu.org>
3971 * lisp.mk (lisp): Update for more files being compiled now.
3973 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
3975 * lread.c: Remove `read_pure' which makes no difference.
3976 (read_pure): Remove var.
3977 (unreadpure): Remove function.
3978 (readevalloop): Don't call read_list with -1 flag.
3979 (read1, read_vector): Don't test read_pure any more.
3980 (read_list): Simplify.
3982 * fileio.c, character.h: Minor style tweaks.
3984 2012-05-24 Dmitry Antipov <dmantipov@yandex.ru>
3986 * window.h (clip_changed): Remove useless declaration.
3988 2012-05-22 Juanma Barranquero <lekktu@gmail.com>
3990 * makefile.w32-in: Follow-up to 2012-05-22T16:20:27Z!eggert@cs.ucla.edu.
3991 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
3993 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
3996 This directory predates autoconf and is no longer needed nowadays.
3997 Move its few remaining bits of functionality to where they're needed.
3998 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:
3999 * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:
4000 * m/template.h: Remove.
4001 * Makefile.in (M_FILE): Remove. All uses removed.
4002 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS):
4003 * lisp.h (USE_LSB_TAG):
4004 * mem-limits.h (EXCEEDS_LISP_PTR):
4005 Use VAL_MAX, not VALBITS, in #if.
4006 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
4007 (EMACS_UINT): Define unconditionally now.
4008 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
4009 (BITS_PER_EMACS_INT): New constants, replacing
4010 what used to be in config.h, but not useful in #if.
4011 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
4012 define them any more.
4013 (VAL_MAX): New macro.
4015 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
4016 BITS_PER_EMACS_INT, in #if.
4017 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
4018 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
4019 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
4020 * s/ms-w32.h (DATA_START):
4021 Move here from removed file m/intel386.h.
4022 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
4023 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
4025 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
4027 Assume C89 or later.
4028 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
4029 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
4031 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.
4032 * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):
4033 * textprop.c, tparam.c (NULL): Remove.
4034 * ralloc.c, vm-limit.c (POINTER): Assume void * works.
4035 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
4036 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
4037 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
4038 * xterm.c (input_signal_count): Assume volatile works.
4040 2012-05-21 Ken Brown <kbrown@cornell.edu>
4042 * xgselect.c (xg_select): Fix first argument in call to 'select'
4045 2012-05-20 Ken Brown <kbrown@cornell.edu>
4047 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
4048 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
4050 2012-05-19 Ken Brown <kbrown@cornell.edu>
4052 * xfns.c (x_in_use): Remove `static' qualifier.
4053 * xterm.h (x_in_use): Declare.
4054 * xgselect.c: Include xterm.h.
4055 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
4056 and `display_arg' (bug#9754).
4058 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
4060 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
4062 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
4063 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
4065 2012-05-18 Eli Zaretskii <eliz@gnu.org>
4067 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
4069 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
4070 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
4072 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
4073 reference to image_cache->refcount.
4074 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
4076 2012-05-17 Juri Linkov <juri@jurta.org>
4078 * search.c (Fword_search_regexp, Fword_search_backward)
4079 (Fword_search_forward, Fword_search_backward_lax)
4080 (Fword_search_forward_lax): Move functions to isearch.el
4081 (bug#10145, bug#11381).
4083 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
4085 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
4087 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
4089 * lread.c (init_obarray): Declare Qt and Qnil as special.
4091 2012-05-14 Glenn Morris <rgm@gnu.org>
4093 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
4094 Put "libexec" before "bin", for the sake of init_callproc_1.
4096 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
4098 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
4100 * unexaix.c: Port to more-recent AIX compilers.
4101 (report_error, report_error_1, make_hdr, copy_sym)
4102 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
4103 Make arguments const char *, not char *, to avoid violations of C
4104 standard and to fix some AIX warnings reported by Gilles Pion.
4106 2012-05-14 Eli Zaretskii <eliz@gnu.org>
4108 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
4109 already have overlays loaded.
4110 (handle_single_display_spec): Before returning without displaying
4111 fringe bitmap, synchronize the bidi iterator with the main display
4112 iterator, by calling iterate_out_of_display_property.
4113 (iterate_out_of_display_property): Detect buffer iteration by
4114 testing that it->string is a Lisp string.
4115 (get_next_display_element): When the current object is exhausted,
4116 and there's something on it->stack, call set_iterator_to_next to
4117 proceed with what's on the stack, instead of returning zero.
4118 (set_iterator_to_next): If called at the end of a Lisp string,
4119 proceed to consider_string_end without incrementing string
4120 position. Don't increment display vector index past the end of
4121 the display vector. (Bug#11417)
4122 (pos_visible_p): Don't report a position visible when move_it_to
4123 stopped at the last line of window, which happens to be scanned
4124 backwards by the bidi iteration. (Bug#11464)
4126 2012-05-14 Eli Zaretskii <eliz@gnu.org>
4128 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
4129 and right-margin display specs even if the spec is invalid or we
4130 are on a TTY, and thus unable to display on the fringes.
4131 That's because the text with the property will not be displayed anyway,
4132 so we need to signal to the caller that this is a "replacing"
4133 display spec. This fixes display when the spec is invalid or we
4136 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
4138 * unexaix.c (make_hdr): Fix typo in prototype.
4139 This bug broke the build on AIX. Problem reported by Gilles Pion.
4141 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
4143 * keyboard.c (kbd_buffer_get_event): Read special events also in
4144 batch mode. (Bug#11415)
4146 2012-05-12 Glenn Morris <rgm@gnu.org>
4148 * ns.mk: Update for ns_appbindir no longer having trailing "/".
4150 2012-05-12 Eli Zaretskii <eliz@gnu.org>
4152 * lisp.mk (lisp): Add newcomment.elc.
4154 2012-05-12 Glenn Morris <rgm@gnu.org>
4156 * Makefile.in (MKDIR_P): New, set by configure.
4157 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
4159 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
4161 Remove unused function hourglass_started.
4162 * dispextern.h (hourglass_started):
4163 * w32fns.c (hourglass_started):
4164 * xdisp.c (hourglass_started): Remove.
4166 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
4168 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
4169 Update dependencies.
4171 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
4173 * xgselect.c (xg_select): Put maxfds+1 into a var.
4174 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
4176 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
4178 2012-05-10 Dave Abrahams <dave@boostpro.com>
4180 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
4181 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
4183 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
4185 * dbusbind.c (xd_registered_buses): New internal Lisp object.
4186 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
4187 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
4188 Initialize xd_registered_buses.
4190 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
4192 Untag more efficiently if USE_LSB_TAG.
4193 This is based on a proposal by YAMAMOTO Mitsuharu in
4194 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
4195 For an admittedly artificial (nth 8000 longlist) benchmark on
4196 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
4197 Emacs's overall text size by 1%.
4198 * lisp.h (XUNTAG): New macro.
4199 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
4200 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
4201 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
4202 * eval.c (Fautoload):
4203 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
4204 * frame.h (XFRAME): Use XUNTAG.
4206 Port recent dbusbind.c changes to 32-bit --with-wide-int.
4207 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
4208 Remove unportable assumptions about print widths of types like
4210 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
4211 intptr_t when converting between pointer and integer, to avoid GCC
4212 warnings about wrong width.
4214 2012-05-09 Eli Zaretskii <eliz@gnu.org>
4216 * w32proc.c (new_child): Force Windows to reserve only 64KB of
4217 stack for each reader_thread, instead of defaulting to 8MB
4218 determined by the linker. This avoids failures in creating
4219 subprocesses on Windows 7, see the discussion in this thread:
4220 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
4222 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
4224 Fix up display of the *Minibuf-0* buffer in the mini window.
4225 * keyboard.c (read_char): Don't clear the echo area if there's no
4227 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
4228 contents of *Minibuf-0*) if there's no message displayed in its stead.
4230 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
4232 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
4235 2012-05-06 Chong Yidong <cyd@gnu.org>
4237 * lisp.mk (lisp): Update.
4239 2012-05-05 Jim Meyering <meyering@redhat.com>
4241 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
4243 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
4245 * data.c (PUT_ERROR): New macro.
4246 (syms_of_data): Use it. Add new error type `user-error'.
4247 * undo.c (user_error): New function.
4248 (Fprimitive_undo): Use it.
4249 * print.c (print_error_message): Adjust print style for `user-error'.
4250 * keyboard.c (user_error): New function.
4251 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
4253 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
4255 Do not limit current-time-string to years 1000..9999.
4256 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
4257 (Fcurrent_time_string): Support any year that is supported by the
4258 underlying localtime representation. Don't use asctime, as it
4259 has undefined behavior for years outside the range -999..9999.
4261 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
4263 Fix race conditions involving setenv, gmtime, localtime, asctime.
4264 Without this fix, interrupts could mess up code that uses these
4265 nonreentrant functions, since setting TZ invalidates existing
4266 tm_zone or tzname values, and since most of these functions return
4267 pointers to static storage.
4268 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
4269 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
4270 Grow the critical sections to include not just invoking
4271 localtime/gmtime, but also accessing these functions' results
4272 including their tm_zone values if any, and any related TZ setting.
4273 (format_time_string): Last arg is now struct tm *, not struct tm **,
4274 so that the struct tm is saved in the critical section.
4275 All callers changed. Simplify allocation of initial buffer, partly
4276 motivated by the fact that memory allocation needs to be outside
4277 the critical section.
4279 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
4281 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
4282 with RESET_INTERVAL.
4284 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
4285 Remove duplicated buffer name initialization.
4287 2012-05-02 Jim Meyering <jim@meyering.net>
4289 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
4291 * xfns.c (x_window): Use xstrdup (Bug#11375).
4293 2012-05-02 Eli Zaretskii <eliz@gnu.org>
4295 * xdisp.c (pos_visible_p): If already at a newline from the
4296 display string before the 'while' loop, don't walk back the glyphs
4297 from it3.glyph_row. Solves assertion violation when the display
4298 string begins with a newline (egg.el). (Bug#11367)
4300 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
4302 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
4305 2012-05-01 Glenn Morris <rgm@gnu.org>
4307 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
4308 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
4309 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
4310 All were removed before 23.1.
4312 * dispnew.c: Remove HAVE_LIBNCURSES test;
4313 it is always true on relevant platforms.
4315 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
4316 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
4318 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
4320 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
4322 * .gdbinit (xpr): Remove checks for no longer existing misc types.
4323 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
4326 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
4328 Do not avoid creating empty evaporating overlays (Bug#9642).
4329 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
4330 That is, do not delete an evaporating overlay if it becomes
4331 empty after its bounds are adjusted to fit within its buffer.
4332 This fix caused other problems, and I'm reverting it until we get
4333 to the bottom of them.
4335 2012-04-27 Chong Yidong <cyd@gnu.org>
4337 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
4339 2012-04-27 Eli Zaretskii <eliz@gnu.org>
4341 * xdisp.c (pos_visible_p): If the window start position is beyond
4342 ZV, start the display from buffer beginning. Prevents assertion
4343 violation in init_iterator when the minibuffer window is scrolled
4346 * window.c (window_scroll_pixel_based): Likewise.
4348 2012-04-27 Chong Yidong <cyd@gnu.org>
4350 * keymap.c (where_is_internal): Doc fix (Bug#10872).
4352 2012-04-27 Glenn Morris <rgm@gnu.org>
4354 * fileio.c (Fcopy_file, Fset_file_selinux_context):
4355 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
4357 2012-04-27 Eli Zaretskii <eliz@gnu.org>
4359 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
4360 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
4362 2012-04-26 Eli Zaretskii <eliz@gnu.org>
4364 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
4365 display element, check also the underlying string or buffer
4366 character. (Bug#11341)
4368 * w32menu.c: Include w32heap.h.
4369 (add_menu_item): If the call to AppendMenuW (via
4370 unicode_append_menu) fails, disable Unicode menus only if we are
4371 running on Windows 9X/Me.
4373 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
4375 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
4376 (xgetint): Add missing shift for LSB tags.
4378 2012-04-24 Martin Rudalics <rudalics@gmx.at>
4380 * keyboard.c (read_char): Don't wipe echo area for select window
4381 events: These might get delayed via `mouse-autoselect-window'
4384 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
4386 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
4387 manipulation of :loaded-from data.
4389 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
4391 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
4392 now a cons (bug#11311).
4394 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
4396 Do not create empty overlays with the evaporate property (Bug#9642).
4397 * buffer.c (Fmove_overlay): Delete an evaporating overlay
4398 if it becomes empty after its bounds are adjusted to fit within
4399 its buffer. Without this fix, in a nonempty buffer (let ((o
4400 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
4401 yields an empty overlay that has the evaporate property, which is
4402 not supposed to happen.
4404 Fix minor GTK3 problems found by static checking.
4405 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
4406 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
4407 (struct _EmacsFixedClass, emacs_fixed_get_type):
4408 Move decls here from emacsgtkfixed.h, since they needn't be public.
4409 (emacs_fixed_get_type): Now static.
4410 (emacs_fixed_class_init): Omit unused local.
4411 (emacs_fixed_child_type): Remove; unused.
4412 * emacsgtkfixed.h (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
4413 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
4414 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
4415 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
4416 (EMACS_FIXED_GET_CLASS): Remove; unused.
4417 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.

4501 * alloc.c (emacs_blocked_malloc) [GC_MALLOC_CHECK]:
4502 Do not assume ptrdiff_t is the same width as 'int'.
4504 * alloc.c: Handle unusual debugging option combinations.
4505 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
4506 since the two debugging options are incompatible.
4507 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
4509 (mem_init, mem_insert, mem_insert_fixup):
4510 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

4542 (print_object): Check for cycles even when print-circle is nil and
4543 print-gensym is t, but only check print_depth if print-circle is nil.
4545 2012-04-20 Chong Yidong <cyd@gnu.org>
4547 * process.c (wait_reading_process_output): If EIO occurs on a pty,

4561 row, return zero immediately.
4562 (try_cursor_movement): If inside continuation line, don't back up
4563 farther than the first row after the header line, if any.
4564 Don't consider the header-line row as "partially visible", even if

4603 New extern decls, to avoid calling undeclared functions.
4604 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
4605 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
4606 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.

4608 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
4609 Remove one incorrect comment and fix another.

4623 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
4624 Remove decls. This fixes an "It stinks!".

4628 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
4630 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

4643 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
4644 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
4645 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
4646 * s/netbsd.h, s/sol2-6.h:
4647 Remove definition of GC_MARK_STACK, since the default now works.
4648 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
4649 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
4650 no longer the default.
4651 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
4653 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

4676 2012-04-11 Daniel Colascione <dancol@dancol.org>
4678 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
4679 against is gone. It's better to use vfork now so that when Cygwin
4680 gains a new, working vfork, we use it automatically (bug#10398).
4682 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

4703 being loaded (bug#10424).
4705 2012-04-09 Glenn Morris <rgm@gnu.org>
4707 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
4708 not just in the obarray, before snarfing them. (Bug#11036)

4735 * minibuf.c (Fread_variable): Callers changed.
4737 2012-04-09 Eli Zaretskii <eliz@gnu.org>
4739 * xdisp.c (set_cursor_from_row): If the display string appears in
4740 the buffer at position that is closer to point than the position
4741 after the display string, display the cursor on the first glyph of
4742 the display string. Fixes cursor display when a 'display' text
4743 property immediately follows invisible text. (Bug#11094)
4745 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
4747 composite.c: use 'double' consistently
4748 * composite.c (get_composition_id): Use 'double' consistently
4749 instead of converting 'float' to 'double' and vice versa; this is
4750 easier to understand and avoids a GCC warning.
4752 2012-04-09 Glenn Morris <rgm@gnu.org>
4754 * Makefile.in: Generate leim-list with bootstrap-emacs, in

4799 [!WINDOWSNT]: New macros.
4800 (init_libxml2_functions, libxml2_loaded_p): New functions.
4801 (parse_region): Call fn_xmlCheckVersion instead of using the macro
4802 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
4803 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
4804 Calls xmlCleanupParser only if libxml2 was loaded (or statically
4806 (Flibxml_parse_html_region, Flibxml_parse_xml_region):

4824 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
4825 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
4826 about subtle differences between FETCH_CHAR* and STRING_CHAR*
4827 macros related to unification of CJK characters. For the details,
4828 see the discussion following the message here:
4829 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
4831 2012-04-04 Chong Yidong <cyd@gnu.org>

4847 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
4848 position we get to after a call to move_it_to fails the
4849 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
4850 only if we wind up in a string from display property. (Bug#11063)
4852 * window.c (Fdelete_other_windows_internal): Invalidate the row
4853 and column information about mouse highlight, so that redisplay
4854 restores it after reallocating the glyph matrices. (Bug#7464)
4856 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
4857 string comes from a `display' text property, use the buffer
4858 position of that property as if we actually saw that position in
4860 (move_it_by_lines): Remove the assertion that
4861 "it->current_x == 0 && it->hpos == 0" which can be legitimately
4862 violated when there's a before-string at the beginning of a line.
4865 2012-03-30 Eli Zaretskii <eliz@gnu.org>

4890 bit length of glyphless.ch to 25 (Bug#11082).
4892 2012-03-26 Chong Yidong <cyd@gnu.org>
4894 * keyboard.c (Vselection_inhibit_update_commands): New variable.
4895 (command_loop_1): Use it; inhibit selection update for
4896 handle-select-window too (Bug#8996).
4898 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
4900 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
4902 2012-03-25 Kenichi Handa <handa@m17n.org>
4904 * dispextern.h (struct glyph): Change the bit length of
4905 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
4907 2012-03-24 Eli Zaretskii <eliz@gnu.org>
4909 * s/ms-w32.h (tzname): Include time.h before redirecting to
4910 _tzname. Fixes the MSVC build. (Bug#9960)

4914 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
4917 * xterm.c (XTread_socket): Only modify handling_signal if
4918 !SYNC_INPUT. (Bug#11080)
4920 2012-03-23 Eli Zaretskii <eliz@gnu.org>
4922 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
4923 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
4924 when fetching a multibyte character consumes more bytes than
4925 CHAR_BYTES returns, due to unification of CJK characters in
4926 string_char. (Bug#11073)
4928 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
4930 * process.c (wait_reading_process_output): Handle pty disconnect
4931 by refraining from sending oneself a SIGCHLD (bug#10933).

4948 * w32proc.c (Fw32_set_console_codepage)
4949 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
4952 2012-03-20 Chong Yidong <cyd@gnu.org>
4954 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
4955 to reflect default non-nil value of redisplay-dont-pause.
4957 2012-03-19 Kenichi Handa <handa@m17n.org>
4959 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
4960 it fit in a valid range (Bug#11003).
4962 2012-03-18 Eli Zaretskii <eliz@gnu.org>
4964 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
4965 that is not from display property, accept the row as a "cursor
4966 row" if one of the string's character has a non-nil `cursor'
4967 property. Fixes cursor positioning when there are newlines in
4968 overlay strings, e.g. in icomplete.el. (Bug#11035)
4970 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
4972 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
4974 2012-03-12 Chong Yidong <cyd@gnu.org>
4976 * eval.c (inhibit_lisp_code): Rename from
4977 inhibit_window_configuration_change_hook; move from window.c.
4979 * xfns.c (unwind_create_frame_1, Fx_create_frame):
4980 * window.c (run_window_configuration_change_hook)
4981 (syms_of_window): Callers changed.
4983 2012-03-11 Chong Yidong <cyd@gnu.org>

4996 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
4998 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
5000 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
5001 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
5004 2012-03-03 Glenn Morris <rgm@gnu.org>
5006 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
5008 2012-03-02 Eli Zaretskii <eliz@gnu.org>
5010 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
5011 position past the first glyph_row that ends at ZV. (Bug#10902)
5012 (redisplay_window, next_element_from_string): Fix typos in
5014 (redisplay_window): Pass to move_it_vertically the margin in
5015 pixels, not in screen lines.
5017 2012-03-02 Glenn Morris <rgm@gnu.org>
5019 * buffer.c (buffer-list-update-hook): Doc fix.
5021 2012-02-29 Eli Zaretskii <eliz@gnu.org>

5024 push_it before setting up the iterator for the first overlay
5025 string, even if we have an empty string loaded.
5026 (next_overlay_string): If there's an empty string on the iterator
5027 stack, pop the stack. (Bug#10903)
5029 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
5031 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
5032 Suggested by Stefan Monnier in
5033 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
5034 * alloc.c (widen_to_Lisp_Object): New static function.
5035 (mark_memory): Also mark Lisp_Objects by fetching pointer words
5036 and widening them to Lisp_Objects. This would work even if
5037 USE_LSB_TAG is defined and wide integers are used, which might
5038 happen in a future version of Emacs.
5040 2012-02-25 Chong Yidong <cyd@gnu.org>
5042 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
5045 * xselect.c (Fx_selection_exists_p): Doc fix.
5046 (x_clipboard_manager_save_all): Print an informative message
5047 before saving to clipboard manager.
5049 2012-02-24 Chong Yidong <cyd@gnu.org>
5051 * keyboard.c (process_special_events): Handle all X selection
5052 requests in kbd_buffer, not just the next one (Bug#8869).
5054 2012-02-23 Chong Yidong <cyd@gnu.org>
5056 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
5057 call when setting menu-bar-lines and tool-bar-lines parameters.
5058 (unwind_create_frame_1): New helper function.
5060 * window.c (inhibit_window_configuration_change_hook): New var.
5061 (run_window_configuration_change_hook): Obey it.
5062 (syms_of_window): Initialize it.
5064 2012-02-22 Chong Yidong <cyd@gnu.org>
5066 * xterm.c (x_draw_image_relief): Add missing type check for
5067 Vtool_bar_button_margin (Bug#10743).

5071 * fileio.c (Vfile_name_handler_alist): Doc fix.
5073 * buffer.c (Fget_file_buffer): Protect against invalid file
5074 handler return value.
5076 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
5078 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
5079 when computing $valmask.
5081 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
5082 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
5083 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
5084 It's useless in that case, and it can cause problems on hosts
5085 that allocate halves of EMACS_INT values separately.
5086 Reported by Dan Horák. Diagnosed by Andreas Schwab in
5087 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
5088 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
5089 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
5090 it avoids undefined behavior on hosts where shifting right by more
5091 than the word width has undefined behavior.
5093 2012-02-19 Chong Yidong <cyd@gnu.org>
5095 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
5096 (Funhandled_file_name_directory, Ffile_name_as_directory)
5097 (Fdirectory_file_name, Fexpand_file_name)

5115 2012-02-15 Chong Yidong <cyd@gnu.org>
5117 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
5118 marked as special. Also, starting docstrings with * is obsolete.
5120 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
5122 * gnutls.c (emacs_gnutls_write): Fix last change.
5124 2012-02-13 Lars Ingebrigtsen <larsi@gnus.org>

5133 2012-02-12 Chong Yidong <cyd@gnu.org>
5135 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
5136 as that creates a dangerous corner case.
5138 * window.c (Fdelete_window_internal): Invalidate the mouse
5139 highlight (Bug#9904).
5141 2012-02-12 Glenn Morris <rgm@gnu.org>

5146 * nsselect.m (Fx_own_selection_internal)
5147 (Fx_disown_selection_internal, Fx_selection_exists_p)
5148 (Fx_selection_owner_p, Fx_get_selection_internal):
5149 Sync docs and argument specs with the xselect.c versions.

5167 2012-02-09 Kenichi Handa <handa@m17n.org>
5169 * coding.c (produce_chars): Fix updating of src_end (Bug#10701).
5171 2012-02-07 Chong Yidong <cyd@gnu.org>
5173 * buffer.c (Fbuffer_local_variables)
5174 (buffer_lisp_local_variables): Handle unbound vars correctly;
5175 don't let Qunbound leak into Lisp.
5177 2012-02-07 Glenn Morris <rgm@gnu.org>
5179 * image.c (Fimagemagick_types): Doc fix.
5181 * image.c (imagemagick-render-type): Change it from a lisp object
5182 to an integer. Move the doc here from the lisp manual.

5185 2012-02-06 Chong Yidong <cyd@gnu.org>
5187 * doc.c (store_function_docstring): Avoid applying docstring of
5188 alias to base function (Bug#2603).
5190 2012-02-04 Andreas Schwab <schwab@linux-m68k.org>
5192 * .gdbinit (pp1, pv1): Remove redundant defines.
5195 2012-02-04 Chong Yidong <cyd@gnu.org>
5197 * nsterm.m: Declare a global (Bug#10694).

5202 Include --enable-checking, if specified, in the return value.
5204 2012-02-04 Martin Rudalics <rudalics@gmx.at>
5206 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
5207 after rounding frame sizes. (Bug#9723)

5211 * keyboard.c (adjust_point_for_property): Don't position point
5212 before BEGV. (Bug#10696)
5214 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
5216 Handle overflow when computing char display width (Bug#9496).
5217 * character.c (char_width): Return EMACS_INT, not int.
5218 (char_width, c_string_width): Check for overflow when
5219 computing the width; this is possible now that individual
5220 characters can have unbounded width. Problem introduced
5221 by merge from Emacs 23 on 2012-01-19.
5223 2012-02-02 Michael Albinus <michael.albinus@gmx.de>
5225 * dbusbind.c (Fdbus_register_method): Mention the return value

5238 2012-02-02 Kenichi Handa <handa@m17n.org>
5240 (x_produce_glyphs): Cancel previous change. If cmp->glyph_len is
5241 0, do not call append_composite_glyph.

5245 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
5247 (x_produce_glyphs): If the component of a composition is a null
5248 string, set it->pixel_width to 1 to avoid zero-width glyph.
5250 2012-02-01 Eli Zaretskii <eliz@gnu.org>
5252 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
5253 first 2 arguments are identical. This makes inserting large
5254 output from a subprocess an order of magnitude faster on
5255 MS-Windows, where all sbrk'ed memory is always contiguous.
5257 2012-01-31 Glenn Morris <rgm@gnu.org>

5298 since nil is not allowed anyway.
5300 2012-01-21 Andreas Schwab <schwab@linux-m68k.org>
5302 * process.c (read_process_output): Use p instead of XPROCESS (proc).

5311 2012-01-19 Kenichi Handa <handa@m17n.org>
5313 * character.c (char_width): New function.
5314 (Fchar_width, c_string_width, lisp_string_width):
5315 Use char_width (Bug#9496).
5317 2012-01-16 Martin Rudalics <rudalics@gmx.at>
5319 * window.c (Vwindow_persistent_parameters): New variable.
5320 (Fset_window_configuration, save_window_save): Handle persistent
5323 2012-01-14 Eli Zaretskii <eliz@gnu.org>
5325 * w32fns.c (signal_user_input): Don't do a QUIT, to avoid
5326 thrashing the stack of the thread. (Bug#9087)

5337 he end column for display of highlight that ends on a newline
5340 2012-01-11 Glenn Morris <rgm@gnu.org>
5342 * lread.c (init_lread): If no-site-lisp, remove site-lisp dirs
5343 from load-path also when installation-directory is nil. (Bug#10208)
5345 2012-01-10 Glenn Morris <rgm@gnu.org>
5347 * emacs.c (syms_of_emacs) <installation-directory>: Doc fix.

5350 Update template values to be closer to their typical values these days.
5352 2012-01-09 Eli Zaretskii <eliz@gnu.org>
5354 * xdisp.c (rows_from_pos_range): Accept additional argument
5355 DISP_STRING, and accept any glyph in a row whose object is that
5356 string as eligible for mouse highlight. Fixes mouse highlight of
5357 display strings from overlays. (Bug#10464)
5359 2012-01-07 Paul Eggert <eggert@cs.ucla.edu>
5361 emacs: fix an auto-save permissions race condition (Bug#10400)
5362 * fileio.c (auto_saving_dir_umask): New static var.
5363 (Fmake_directory_internal): Use it.
5364 (do_auto_save_make_dir): Set it, instead of invoking chmod after
5365 creating the directory. The old code temporarily assigns
5366 too-generous permissions to the directory.
5367 (do_auto_save_eh): Clear it.
5368 (Fdo_auto_save): Catch all errors, not just file errors, so
5369 that the var is always cleared.
5371 2012-01-07 Eli Zaretskii <eliz@gnu.org>
5373 * search.c (scan_buffer): Pass character positions to
5374 know_region_cache, not byte positions. (Bug#6540)
5376 2012-01-07 LynX <_LynX@bk.ru> (tiny change)
5378 * w32.c (sys_rename): Report EXDEV when rename of a directory

5874 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
5875 is set, removing the need for VIRT_ADDRESS_VARIES.
5876 (PURE_P): Use a more-efficient implementation that needs just one
5877 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
5878 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
5879 to 4 (xorl, subq, cmpq, setbe).
5880 * alloc.c (pure): Always extern now, since that's the
5881 VIRT_ADDR_VARIES behavior.
5882 (PURE_POINTER_P): Use a single comparison, not two, for
5883 consistency with the new puresize.h.
5884 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
5885 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:
5886 Remove VIRT_ADDR_VARIES no longer needed.
5888 2011-11-19 Eli Zaretskii <eliz@gnu.org>
5890 * xdisp.c (x_write_glyphs, draw_phys_cursor_glyph)
5891 (erase_phys_cursor, update_window_cursor, show_mouse_face)
5892 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
5893 behave as if the cursor position were at the window margin.
5895 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
5896 and the cursor position is out of bounds, behave as if the cursor
5897 position were at the window margin. (Bug#10075)
5899 2011-11-18 Chong Yidong <cyd@gnu.org>
5901 * window.c (Fwindow_combination_limit): Make first argument
5902 non-optional, since it is meaningless for live windows like the

5916 * dispnew.c (swap_glyph_pointers): Swap the used[] arrays and the
5917 hash values of the two rows.
5918 (copy_row_except_pointers): Preserve the used[] arrays and the
5919 hash values of the two rows. (Bug#10035)
5920 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
5922 * xdisp.c (row_hash): New function, body extracted from
5923 compute_line_metrics.
5924 (compute_line_metrics): Call row_hash, instead of computing the
5927 * dispnew.c (verify_row_hash): Call row_hash for computing the
5928 hash code of a row, instead of duplicating code from xdisp.c.
5930 * dispextern.h (row_hash): Add prototype.
5932 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
5934 * frame.c (delete_frame): Don't delete the terminal when the last
5935 X frame is closed if emacs is built with GTK toolkit.

5966 * image.c (imagemagick_load_image): Fix typo.
5968 2011-11-14 Eli Zaretskii <eliz@gnu.org>
5970 * xdisp.c (display_line): Move the call to
5971 highlight_trailing_whitespace before the call to
5972 compute_line_metrics, since the latter needs to see the final
5973 faces of all the glyphs to compute ROW's hash value.
5974 Fixes assertion violations in row_equal_p. (Bug#10035)
5976 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
5978 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,

5983 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
5984 with user-defined heap size. Bump the default size of the temacs
5985 heap to 27MB, to avoid memory warning when running temacs.
5986 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
5988 * dispnew.c (scrolling_window): Fix incorrect indices in accessing

6008 * nsfns.m (unwind_create_frame):
6009 * w32fns.c (unwind_create_frame): Use Fmemq to check if frame is in
6010 Vframe_list (Bug#9999).
6012 2011-11-11 Dmitry Antipov <dmantipov@yandex.ru>
6014 * xdisp.c (syms_of_xdisp): Remove duplicated definition of Qtext.

6035 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
6037 Avoid some portability problems by eschewing 'extern inline' functions.
6038 The trivial performance wins aren't worth the portability hassles; see
6039 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
6041 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
6042 (window_box_width, window_box_left, window_box_left_offset)
6043 (window_box_right, window_box_right_offset): Undo previous change,
6044 by removing the "extern"s.
6045 * intervals.c (adjust_intervals_for_insertion)
6046 (adjust_intervals_for_deletion): Undo previous change,
6047 making these static again.
6048 (offset_intervals, temp_set_point_both, temp_set_point)
6049 (copy_intervals_to_string): No longer inline.
6050 * xdisp.c (window_text_bottom_y, window_box_width)

6089 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
6090 This is also needed for porting to any host where GC_MARK_STACK is
6091 not GC_MAKE_GCPROS_NOOPS.
6092 (which_symbols): Use it.
6094 2011-11-07 Kenichi Handa <handa@m17n.org>

6107 * xmenu.c (cleanup_widget_value_tree): New function.
6108 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
6109 calling free_menubar_widget_value_tree directly (Bug#9830).

6115 (window_box_width, window_box_left, window_box_left_offset)
6116 (window_box_right, window_box_right_offset): Declare extern.
6117 Otherwise, these inline functions do not conform to C99 and
6118 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
6119 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
6120 * intervals.c (adjust_intervals_for_insertion)
6121 (adjust_intervals_for_deletion): Now extern, because otherwise the
6122 extern inline functions 'offset_intervals' couldn't refer to it.
6123 (static_offset_intervals): Remove.
6124 (offset_intervals): Rewrite using the old contents of
6125 static_offset_intervals. The old version didn't conform to C99
6126 because an extern inline function contained a reference to an
6127 identifier with static linkage.
6129 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
6131 * keyboard.c (interrupt_signal): Don't call kill-emacs while in
6134 2011-11-06 Eli Zaretskii <eliz@gnu.org>
6136 * xdisp.c (init_iterator, reseat_to_string): Don't set the
6137 iterator's bidi_p flag if Vpurify_flag is non-nil. (Bug#9963)
6138 (Fcurrent_bidi_paragraph_direction): If Vpurify_flag is non-nil,
6139 return Qleft_to_right.

6146 (Fwindow_use_time, Fwindow_total_size, Fwindow_normal_size)
6147 (Fwindow_new_normal, Fwindow_left_column, Fwindow_top_line)
6148 (Fwindow_margins, Fwindow_fringes, Fwindow_scroll_bars)
6149 (Fwindow_vscroll): Doc fix.
6150 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
6151 argument, since it makes no sense to pass a live window and for
6152 consistency with window-child.

6177 2011-11-05 Jan Djärv <jan.h.d@swipnet.se>
6179 * nsfns.m: Declare image_cache_refcount if GLYPH_DEBUG.
6180 (unwind_create_frame): New function (Bug#9943).
6181 (Fx_create_frame): Restructure code to be more similar to the one in
6182 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).
6183 Initialize image_cache_refcount if GLYPH_DEBUG (Bug#9943).
6184 Move terminal->reference_count++ just before making the frame official
6187 * nsterm.m (x_free_frame_resources): New function.
6188 (x_destroy_window): Move code to x_free_frame_resources.
6190 * xfns.c (unwind_create_frame): Fix comment.
6191 (Fx_create_frame, x_create_tip_frame):
6192 Move terminal->reference_count++ just before making the frame
6193 official. Move initialization of image_cache_refcount and
6194 dpyinfo_refcount before calling init_frame_faces (Bug#9943).
6196 2011-11-05 Eli Zaretskii <eliz@gnu.org>
6198 Support MSVC build with newer versions of Visual Studio.
6199 * makefile.w32-in (TAGS-gmake): Don't use $(patsubst ...), as

6345 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
6347 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
6349 2011-10-28 Eli Zaretskii <eliz@gnu.org>
6351 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
6352 <oslsachem@gmail.com> for helping to debug this.
6354 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
6355 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
6356 (g_b_init_get_glyph_outline_w): New static variables.
6357 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
6358 (GetGlyphOutlineW_Proc): New typedefs.
6359 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
6360 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
6362 (w32font_open_internal, compute_metrics):
6363 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
6364 instead of calling the "wide" APIs directly.
6366 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
6368 * w32.h (syms_of_w32font): Add prototype.
6370 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
6372 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
6373 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
6374 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
6375 (Fmove_to_window_line): Doc fix.
6377 2011-10-27 Chong Yidong <cyd@gnu.org>
6379 * process.c (make_process): Set gnutls_state to NULL.
6381 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
6382 non-NULL, regardless of GNUTLS_INITSTAGE.
6383 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
6384 an error. Set process slots as soon as we allocate them.
6386 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
6388 2011-10-27 Chong Yidong <cyd@gnu.org>
6390 * gnutls.c (emacs_gnutls_deinit): New function.
6391 Deallocate credentials structures as well as calling gnutls_deinit.
6392 (Fgnutls_deinit, Fgnutls_boot): Use it.
6394 * process.c (make_process): Initialize GnuTLS credentials to NULL.
6395 (deactivate_process): Call emacs_gnutls_deinit.
6397 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
6399 * image.c (x_create_x_image_and_pixmap):
6400 * w32.c (sys_rename, w32_delayed_load):
6401 * w32font.c (fill_in_logfont):
6402 * w32reg.c (x_get_string_resource): Silence compiler warnings.
6404 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
6406 * w32fns.c (w32_default_color_map): New function,
6407 extracted from Fw32_default_color_map.
6408 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
6410 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
6412 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
6414 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
6416 * keyboard.c (test_undefined): New function (bug#9751).
6417 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
6419 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
6421 * sysdep.c (init_sys_modes): Fix the check for the controlling
6422 terminal (Bug#6649).
6424 2011-10-20 Eli Zaretskii <eliz@gnu.org>
6426 * dispextern.h (struct bidi_it): New member next_en_type.
6428 * bidi.c (bidi_line_init): Initialize the next_en_type member.
6429 (bidi_resolve_explicit_1): When next_en_pos is valid for the
6430 current character, check also for next_en_type being WEAK_EN.
6431 (bidi_resolve_weak): Don't enter the expensive loop if the current
6432 position is before next_en_pos. Record the bidi type of the first
6433 non-ET, non-BN character we find, in addition to its position.
6434 (bidi_level_of_next_char): Invalidate next_en_type when
6435 next_en_pos is over-stepped.
6437 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
6439 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
6440 * editfns.c: Rewrite current-time-zone so that it invokes
6441 the equivalent of (format-time-string "%Z") to get the time zone name.
6442 This fixes a bug when the time zone name contains characters that
6443 need converting from the system time locale to Emacs internal format.
6444 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
6445 that patch fixed format-time-string to do the conversion, but
6446 I forgot to fix current-time-zone.
6447 (format_time_string): New function, containing most of
6448 what Fformat_time_string used to contain.
6449 (Fformat_time_string): Rewrite in terms of format_time_string.
6450 This doesn't change this function's behavior.
6451 (current-time-zone): Rewrite to use format_time_string.
6452 This fixes the bug reported by Michael Schierl in
6453 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
6454 Jason Rumney's 2007-06-07 change worked around this bug, but
6456 * systime.h (tzname, timezone): Remove no-longer-used declarations.
6458 2011-10-19 Eli Zaretskii <eliz@gnu.org>
6460 * xdisp.c (start_display): If the character at POS is displayed
6461 via a display vector, reset IT->current.dpvec_index to zero.
6462 (try_window_reusing_current_matrix): If a line ends in a display
6463 vector or the next line starts in a display vector, continue
6464 redrawing the window even though the character position of
6465 start_row was reached.
6468 2011-10-18 Chong Yidong <cyd@gnu.org>
6470 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
6471 with nobreak-char-display too.
6473 2011-10-18 Eli Zaretskii <eliz@gnu.org>
6475 Fix part 3 of bug#9771.
6476 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
6477 (bidi_resolve_neutral): Don't enter the expensive loop looking for
6478 non-neutral characters if the current character is a paragraph
6479 separator (a.k.a. Newline). This avoids running the same
6480 expensive loop twice, once when we consume the preceding newline
6481 and the other time when the line actually needs to be displayed.
6482 Avoid the loop when we see neutrals on the base embedding level
6483 following a character whose directionality is the same as the
6484 paragraph's. This avoids running the expensive loop when a line
6485 ends in a long sequence of neutrals, like control characters.
6486 Add assertion against STRONG_AL type. Slightly rearrange code
6487 that determines the type of a neutral given the first non-neutral
6489 (bidi_level_of_next_char): Set next_en_pos to zero when
6490 invalidating its info.
6492 2011-10-17 Eli Zaretskii <eliz@gnu.org>
6494 * xdisp.c (push_display_prop): Determine whether to record string
6495 or buffer position by IT->string, not by IT->method. Allow
6496 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
6497 (move_it_vertically_backward): Don't look for character position
6498 immediately after the newline when in a continuation line.
6501 2011-10-15 Martin Rudalics <rudalics@gmx.at>
6503 * window.c (coordinates_in_window): Rewrite and delabelize
6504 vertical border check. (Bug#5357) (Bug#9618)
6506 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
6508 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
6509 errors in XSetWindowBorder (bug#9310).
6511 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
6513 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
6514 avoid crash when xmalloc overrun checking is enabled.
6516 2011-10-13 Eli Zaretskii <eliz@gnu.org>
6518 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
6519 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
6520 cursor motion with <left> and <right> arrow keys.
6522 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
6523 some callers set that themselves.
6525 2011-10-12 Eli Zaretskii <eliz@gnu.org>
6527 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
6528 display string and the previous row comes from the same string and
6529 is empty. (Bug#9739) (Bug#9738)
6531 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
6533 * doc.c (get_doc_string): Encode file name (bug#9735).
6535 2011-10-12 Eli Zaretskii <eliz@gnu.org>
6537 * bidi.c (bidi_level_of_next_char):
6538 * xdisp.c (get_visually_first_element): Remove old incorrect
6539 comments regarding the Unicode Line Separator character.
6541 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
6543 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
6545 * alloc.c (Fgc_status): Do not access beyond zombies array
6546 boundary if nzombies > MAX_ZOMBIES.
6547 * alloc.c (dump_zombies): Add missing format specifier.
6549 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
6551 * xdisp.c (set_cursor_from_row): Simplify conditionals,
6552 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
6554 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
6555 Some packages use them to denote characters with modifiers.
6557 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
6559 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
6560 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
6561 matching a pp-number. Rename parameter var to var1.
6563 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
6565 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
6567 2011-10-08 Glenn Morris <rgm@gnu.org>
6569 * callint.c (Fcall_interactively): Give a more explicit error for the
6570 'c' case with a non-character input. (Bug#8479)
6572 2011-10-08 Eli Zaretskii <eliz@gnu.org>
6574 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
6576 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
6577 lines that are hscrolled on the left.
6579 * dispnew.c (buffer_posn_from_coords): Account for a possible
6580 presence of header-line. (Bug#4426)
6582 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
6584 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
6585 Don't advertise functionality which we discourage or doesn't work.
6587 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
6589 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
6590 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
6591 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
6592 this makes Emacs dump core during garbage collection on rare
6593 occasions. sizeof is obviously inferior to offsetof here, so
6594 stick with offsetof.
6595 (GC_POINTER_ALIGNMENT): New macro.
6596 (mark_memory): Omit 3rd (offset) arg; caller changed.
6597 Don't assume EMACS_INT alignment is the same as pointer alignment.
6599 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
6601 * keyboard.c (read_key_sequence_remapped): New var.
6602 (read_key_sequence): Compute remapping in the right buffer.
6603 (command_loop_1): Use read_key_sequence's remapping directly.
6605 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
6607 * dired.c (file_name_completion): Don't expand file name.
6608 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
6609 before checking file name handler.
6611 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
6612 they've been requested explicitly (bug#9591).
6614 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
6616 * keymap.c (Fsingle_key_description): Use make_specified_string
6617 instead of build_string to build string from push_key_description.
6620 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
6622 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
6623 This fixes a Y2038 bug on 64-bit hosts.
6624 * buffer.c (reset_buffer):
6625 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
6626 (Fclear_buffer_auto_save_failure):
6627 Use 0, not -1, to represent an unset failure time, since time_t
6628 might not be signed.
6630 Remove dependency on glibc malloc internals.
6631 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6632 Move back here from lisp.h, but with their new implementations.
6633 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
6634 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
6635 * charset.c (charset_table_init): New static var.
6636 (syms_of_charset): Use it instead of xmalloc. This removes a
6637 dependency on glibc malloc internals. See Eli Zaretskii's comment in
6638 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
6639 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6640 Move back to alloc.c.
6641 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
6642 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
6644 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
6646 * nsterm.m (windowDidResize): Call x_set_window_size only when
6647 ns_in_resize is true. Otherwise set pixelwidth/height and
6648 call change_frame_size (Bug#9628).
6650 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
6652 Port --enable-checking=all to Fedora 14 x86-64.
6653 * charset.c (syms_of_charset): Also account for glibc malloc's
6654 internal overhead when calculating the initial malloc maximum.
6656 Port --enable-checking=all to Fedora 14 x86.
6657 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6659 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
6660 (overrun_check_realloc, overrun_check_free):
6661 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
6662 That way, xmalloc returns a properly-aligned pointer even if
6663 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
6664 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
6665 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
6666 into account when calculating the initial malloc maximum.
6667 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6668 Move here from alloc.c, so that charset.c can use it too.
6669 Properly align; the old code wasn't right for common 32-bit hosts
6670 when configured with --enable-checking=all.
6671 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
6672 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
6674 2011-09-29 Eli Zaretskii <eliz@gnu.org>
6676 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
6679 2011-09-28 Eli Zaretskii <eliz@gnu.org>
6681 * xdisp.c (compute_display_string_end): If there's no display
6682 string at CHARPOS, return -1.
6684 * bidi.c (bidi_fetch_char): When compute_display_string_end
6685 returns a negative value, treat the character as a normal
6686 character not covered by a display string. (Bug#9624)
6688 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
6690 * lread.c (Fread_from_string): Fix typo in docstring.
6692 2011-09-27 Eli Zaretskii <eliz@gnu.org>
6694 * xdisp.c (handle_invisible_prop): If invisible text ends on a
6695 newline, reseat the iterator instead of bidi-iterating there one
6696 character at a time. (Bug#9610)
6697 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
6698 TO_CHARPOS if the bidi iterator is at base embedding level.
6700 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
6702 * lread.c (readevalloop): Use correct code for NBSP.
6703 (read1): Likewise. (Bug#9608)
6705 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
6707 * dbusbind.c (Fdbus_register_signal): When service is not
6708 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
6710 2011-09-25 Glenn Morris <rgm@gnu.org>
6712 * buffer.c (truncate-lines): Doc fix.
6714 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
6716 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
6717 (Fset_window_next_buffers): Doc fix.
6719 2011-09-24 Glenn Morris <rgm@gnu.org>
6721 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
6723 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
6725 Fix minor problems found by static checking.
6726 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
6727 * indent.c (Fvertical_motion): Fix == vs = typo.
6729 2011-09-24 Eli Zaretskii <eliz@gnu.org>
6731 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
6732 Default value is now t. Doc fix.
6734 * indent.c (Fvertical_motion): Compute and apply the overshoot
6735 logic when moving up, not only when moving down. Fix the
6736 confusing name and values of the it_overshoot_expected variable;
6737 logic changes accordingly. (Bug#9254) (Bug#9549)
6739 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
6740 CHARPOS is covered by a display string which includes newlines.
6741 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
6742 is covered by a display string with embedded newlines.
6744 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
6746 * dbusbind.c (Fdbus_register_signal): Add match rule to
6747 Vdbus_registered_objects_table. (Bug#9581)
6748 (Fdbus_register_method, Vdbus_registered_objects_table):
6751 2011-09-24 Jim Meyering <meyering@redhat.com>
6753 do not ignore write error for any output size
6754 The previous change was incomplete.
6755 While it makes emacs --batch detect the vast majority of stdout
6756 write failures, errors were still ignored whenever the output size is
6757 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
6758 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
6759 && echo FAIL: ignored write error
6760 FAIL: ignored write error
6761 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
6762 && echo FAIL: ignored write error
6763 FAIL: ignored write error
6764 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
6766 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
6768 * emacs.c (Fkill_emacs): In noninteractive mode exit
6769 non-successfully if a write error occurred on stdout. (Bug#9574)
6771 2011-09-21 Eli Zaretskii <eliz@gnu.org>
6773 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
6776 * dispextern.h (struct it): Update the comment documenting what
6779 2011-09-20 Eli Zaretskii <eliz@gnu.org>
6781 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
6782 a display string, extend search for cursor position to end of row.
6783 (find_row_edges): If the row ends in a newline from a display
6784 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
6785 Handle the case of a display string with multiple newlines.
6786 (Fcurrent_bidi_paragraph_direction): Fix search for previous
6787 non-empty line. Fixes confusing cursor motion with arrow keys at
6788 the beginning of a line that starts with whitespace.
6790 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
6792 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
6795 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
6797 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
6800 2011-09-18 Eli Zaretskii <eliz@gnu.org>
6802 * xdisp.c (display_line): Record maximum and minimum buffer
6803 positions even if no glyphs were produced (e.g., by a zero-width
6804 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
6805 buffer positions that will be removed from the glyph row because
6807 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
6808 column is beyond frame width: don't subtract 1 "pixel" when
6809 computing width of the stretch.
6810 (reseat_at_next_visible_line_start): Undo the change made on
6811 2011-09-17 that saved paragraph information and restored it after
6812 the call to `reseat'. (Bug#9545)
6814 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6816 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
6817 and turn window cursor on if cleared (Bug#9415).
6819 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
6821 * search.c (boyer_moore): Take unibyte characters from pattern
6822 literally. (Bug#9458)
6824 2011-09-18 Eli Zaretskii <eliz@gnu.org>
6826 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
6828 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
6830 Fix minor problem found by static checking.
6831 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
6832 initialized, to pacify gcc -Wuninitialized.
6834 * fileio.c: Report proper errno when syscall falls.
6835 (Finsert_file_contents): Save and restore errno,
6836 so that report_file_error outputs the correct diagnostic.
6837 (Fwrite_region) [CLASH_DETECTION]: Likewise.
6839 2011-09-18 Eli Zaretskii <eliz@gnu.org>
6841 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
6843 2011-09-17 Eli Zaretskii <eliz@gnu.org>
6845 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
6846 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
6848 2011-09-17 Eli Zaretskii <eliz@gnu.org>
6850 * xdisp.c (reseat_at_next_visible_line_start): Keep information
6851 about the current paragraph and restore it after the call to reseat.
6853 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
6854 (bidi_find_paragraph_start): Search back for paragraph beginning
6855 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
6856 (bidi_move_to_visually_next): Only trigger paragraph-related
6857 computations when the last character is a newline or at EOB, not
6858 just any NEUTRAL_B. (Bug#9470)
6860 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
6861 truncated lines if point is covered by a display string. (Bug#9524)
6863 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
6865 * xselect.c: Relax test for outgoing X longs (Bug#9498).
6866 (cons_to_x_long): New function.
6867 (lisp_data_to_selection_data): Use it. Correct the test for
6868 short-versus-long data; it was negated. Break out of vector
6869 loop, for efficiency, when a long datum is discovered.
6871 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
6873 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
6875 2011-09-16 Eli Zaretskii <eliz@gnu.org>
6877 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
6878 GCC PR/17406) by declaring this function with external scope.
6880 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
6882 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
6883 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
6885 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
6887 * editfns.c (Fformat): Correctly handle text properties on "%%".
6889 2011-09-15 Eli Zaretskii <eliz@gnu.org>
6891 * xterm.c (x_draw_composite_glyph_string_foreground):
6892 * w32term.c (x_draw_composite_glyph_string_foreground):
6893 * term.c (encode_terminal_code):
6894 * composite.c (composition_update_it, get_composition_id):
6895 * xdisp.c (get_next_display_element)
6896 (fill_composite_glyph_string): Add comments about special meaning
6897 of TAB characters in a composition.
6899 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
6901 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
6902 This occurs when processing a multibyte format.
6903 Problem reported by Wolfgang Jenker.
6905 2011-09-15 Johan Bockgård <bojohan@gnu.org>
6907 * xdisp.c (try_cursor_movement): Only check for exact match if
6908 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
6910 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
6912 Remove unused external symbols.
6913 * dispextern.h (calc_pixel_width_or_height): Remove decl.
6914 * xdisp.c (calc_pixel_width_or_height): Now static.
6915 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
6916 * indent.c (check_display_width):
6917 * w32term.c: Fix comment to match code.
6918 * xterm.c, xterm.h (x_catching_errors): Remove.
6920 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
6922 * xselect.c: Use signed conversions more consistently (Bug#9498).
6923 (selection_data_to_lisp_data): Assume incoming selection data are
6924 signed integers, not unsigned. This is to be consistent with
6925 outgoing selection data, which was modified to use signed integers
6926 in as part of the fix to Bug#9196 in response to Jan D.'s comment
6927 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
6928 expects long, not unsigned long.
6930 2011-09-14 Eli Zaretskii <eliz@gnu.org>
6932 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
6933 computation of loop end. Reported by Johan Bockgård
6936 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
6938 * frame.c (Fother_visible_frames_p): Function deleted.
6940 2011-09-12 Eli Zaretskii <eliz@gnu.org>
6942 * indent.c (compute_motion): Process display vector front to back
6943 rather than the other way around. (Bug#2496)
6945 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
6947 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
6949 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
6951 * minibuf.c (Fread_from_minibuffer): Doc fix.
6953 2011-09-11 Eli Zaretskii <eliz@gnu.org>
6955 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
6956 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
6958 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
6960 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
6961 value for non-existent files.
6963 2011-09-11 Eli Zaretskii <eliz@gnu.org>
6965 * fileio.c (Finsert_file_contents): If the file cannot be opened,
6966 set its "size" to -1. This will set the modtime_size field of
6967 the corresponding buffer to -1, which is what
6968 verify-visited-file-modtime expects for files that do not exist.
6971 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
6973 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
6975 * lisp.h: ... from here. push_key_description is no longer
6976 defined in keyboard.c, so its declaration should not be in
6977 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
6978 logically belongs with push_key_description.
6980 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
6982 * buffer.h: Include <sys/types.h> instead of <time.h>.
6983 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
6984 Problem reported by Herbert J. Skuhra.
6986 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
6988 * xml.c (parse_region): Make the parsing work for
6989 non-comment-starting XML files again (bug#9144).
6991 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
6993 * image.c (gif_load): Fix calculation of bottom and right corner.
6996 2011-09-10 Eli Zaretskii <eliz@gnu.org>
6998 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
6999 redisplay in small windows.
7001 2011-09-09 Eli Zaretskii <eliz@gnu.org>
7003 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
7005 2011-09-08 Martin Rudalics <rudalics@gmx.at>
7007 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
7008 Operate on live windows only.
7010 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
7012 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
7014 2011-09-07 Eli Zaretskii <eliz@gnu.org>
7016 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
7017 only under bidi iteration.
7019 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
7021 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
7023 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7025 isnan: Fix porting problem to Solaris 10 with bundled gcc.
7026 Without this fix, the command to link temacs failed due to an
7027 undefined symbol __builtin_isnan. This is because
7028 /usr/include/iso/math_c99.h #defines isnan(x) to
7029 __builtin_isnan(x), but the bundled gcc, which identifies itself
7030 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
7032 * floatfns.c (isnan): #undef, and then #define to a clone of
7034 (Fisnan): Always define, since it's always available now.
7035 (syms_of_floatfns): Always define isnan at the Lisp level.
7037 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7039 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
7041 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7043 * fileio.c: Fix bugs with large file offsets (Bug#9428).
7044 The previous code assumed that file offsets (off_t values) fit in
7045 EMACS_INT variables, which is not true on typical 32-bit hosts.
7046 The code messed up by falsely reporting buffer overflow in cases
7047 such as (insert-file-contents "big" nil 1 2) into an empty buffer
7048 when "big" contains more than 2**29 bytes, even though this
7049 inserts just one byte and does not overflow the buffer.
7050 (Finsert_file_contents): Store file offsets as off_t
7051 values, not as EMACS_INT values. Check for overflow when
7052 converting between EMACS_INT and off_t. When checking for
7053 buffer overflow or for overlap, take the offsets into account.
7054 Don't use EMACS_INT for small values where int suffices.
7055 When checking for overlap, fix a typo: ZV was used where
7056 ZV_BYTE was intended.
7057 (Fwrite_region): Don't assume off_t fits into 'long'.
7058 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
7060 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
7062 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
7064 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7066 sprintf-related integer and memory overflow issues (Bug#9412).
7068 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
7069 (esprintf, exprintf, evxprintf): New functions.
7070 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
7071 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
7072 (modify_event_symbol): Do not assume that the length of
7073 name_alist_or_stem is safe to alloca and fits in int.
7074 (Fexecute_extended_command): Likewise for function name and binding.
7075 (Frecursion_depth): Wrap around reliably on integer overflow.
7076 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
7077 since some callers pass EMACS_INT values.
7078 (Fsingle_key_description): Don't crash if symbol name contains more
7079 than MAX_ALLOCA bytes.
7080 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
7081 (get_minibuffer): Arg is now EMACS_INT, not int.
7082 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
7083 (esprintf, exprintf, evxprintf): New decls.
7084 * window.h (command_loop_level, minibuf_level): Reflect API changes.
7086 * dbusbind.c (signature_cat): New function.
7087 (xd_signature, Fdbus_register_signal):
7088 Do not overrun buffer; instead, report string overflow.
7090 * dispnew.c (add_window_display_history): Don't overrun buffer.
7091 Truncate instead; this is OK since it's just a log.
7093 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
7094 even if the time zone offset is outlandishly large.
7095 Don't mishandle offset == INT_MIN.
7097 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
7098 when creating daemon; the previous buffer-overflow check was incorrect.
7100 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
7101 which has the guts of the old verror function.
7103 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
7104 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
7106 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
7107 (font_unparse_xlfd): Don't blindly alloca long strings.
7108 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
7109 fits in int, when using sprintf. Use single snprintf to count
7110 length of string rather than counting it via multiple sprintfs;
7111 that's simpler and more reliable.
7112 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
7113 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
7114 sprintf, in case result does not fit in int.
7116 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
7117 (fontset_from_font): Print it.
7119 * frame.c (tty_frame_count): Now printmax_t, not int.
7120 (make_terminal_frame, set_term_frame_name): Print it.
7121 (x_report_frame_params): In X, window IDs are unsigned long,
7122 not signed long, so print them as unsigned.
7123 (validate_x_resource_name): Check for implausibly long names,
7124 and don't assume name length fits in 'int'.
7125 (x_get_resource_string): Don't blindly alloca invocation name;
7126 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
7129 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
7130 (xg_check_special_colors, xg_set_geometry):
7131 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
7133 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
7134 Use esprintf, not sprintf, in case result does not fit in int.
7136 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7137 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
7138 it as a large positive number.
7139 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
7140 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7142 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
7143 in case result does not fit in int.
7145 * print.c (float_to_string): Detect width overflow more reliably.
7146 (print_object): Make sprintf buffer a bit bigger, to avoid potential
7147 buffer overrun. Don't assume list length fits in 'int'. Treat
7148 print length of 0 as 0, not as infinity; to be consistent with other
7149 uses of print length in this function. Don't overflow print length
7150 index. Don't assume hash table size fits in 'long', or that
7151 vectorlike size fits in 'unsigned long'.
7153 * process.c (make_process): Use printmax_t, not int, to format
7154 process-name gensyms.
7156 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
7158 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
7159 to avoid potential buffer overrun.
7161 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
7162 if X resource line is longer than 512 bytes.
7164 * xfns.c (x_window): Make sprintf buffer a bit bigger
7165 to avoid potential buffer overrun.
7167 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
7169 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
7171 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7173 Integer overflow fixes for scrolling, etc.
7174 Without these, Emacs silently mishandles large integers sometimes.
7175 For example, "C-u 4294967297 M-x recenter" was treated as if
7176 it were "C-u 1 M-x recenter" on a typical 64-bit host.
7178 * xdisp.c (try_window_id): Check Emacs fixnum range before
7179 converting to 'int'.
7181 * window.c (window_scroll_line_based, Frecenter):
7182 Check that an Emacs fixnum is in range before assigning it to 'int'.
7183 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
7184 values converted from Emacs fixnums.
7185 (Frecenter): Don't wrap around a line count if it is out of 'int'
7186 range; instead, treat it as an extreme value.
7187 (Fset_window_configuration, compare_window_configurations):
7188 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
7190 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
7191 that can exceed INT_MAX. Check that EMACS_INT value is in range
7192 before assigning it to the (possibly-narrower) index.
7193 (match_limit): Don't assume that a fixnum can fit in 'int'.
7195 * print.c (print_object): Use ptrdiff_t, not int, for index that can
7198 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
7199 (Fvertical_motion): Don't wrap around LINES values that don't fit
7200 in 'int'. Instead, treat them as extreme values. This is good
7201 enough for windows, which can't have more than INT_MAX lines anyway.
7203 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
7205 * Require libxml/parser.h to avoid compilation warning.
7207 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
7209 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
7210 since this reportedly can destroy thread storage.
7212 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
7214 * syntax.c (find_defun_start): Update all cache variables if
7215 exiting early (Bug#9401).
7217 2011-08-30 Eli Zaretskii <eliz@gnu.org>
7219 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
7221 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
7222 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
7223 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
7225 * term.c (tty_append_glyph): New function.
7226 (produce_stretch_glyph): Static function and its prototype deleted.
7228 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
7231 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
7233 * image.c (parse_image_spec): Check for nonnegative, not for positive,
7234 when checking :margin (Bug#9390).
7235 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
7236 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
7237 so that the name doesn't mislead. All uses changed.
7239 2011-08-28 Johan Bockgård <bojohan@gnu.org>
7241 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
7244 2011-08-27 Eli Zaretskii <eliz@gnu.org>
7246 * xdisp.c (move_it_to): Don't bail out early when reaching
7247 position beyond to_charpos, if we are scanning backwards.
7248 (move_it_vertically_backward): When DY == 0, make sure we get to
7249 the first character in the line after the newline.
7251 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
7253 * ccl.c: Improve and simplify overflow checking (Bug#9196).
7254 (ccl_driver): Do not generate an out-of-range pointer.
7255 (Fccl_execute_on_string): Remove unnecessary check for
7256 integer overflow, noted by Stefan Monnier in
7257 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
7258 Remove a FIXME that didn't need fixing.
7259 Simplify the newly-introduced buffer reallocation code.
7261 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
7263 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
7265 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
7267 Integer and memory overflow issues (Bug#9196).
7269 * doc.c (get_doc_string): Rework so that
7270 get_doc_string_buffer_size is the actual buffer size, rather than
7271 being 1 less than the actual buffer size; this makes xpalloc more
7274 * image.c (x_allocate_bitmap_record, cache_image):
7275 * xselect.c (Fx_register_dnd_atom):
7276 Simplify previous changes by using xpalloc.
7278 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
7279 since either will do and ptrdiff_t is convenient with xpalloc.
7281 * charset.c (charset_table_size)
7282 (struct charset_sort_data.priority): Now ptrdiff_t.
7283 (charset_compare): Don't overflow if priorities differ greatly.
7284 (Fsort_charsets): Don't assume list length fits in int.
7285 Check for size-calculation overflow when allocating sort data.

7289 * cmds.c (internal_self_insert): Check for size-calculation overflow.
7291 * composite.h (struct composition.glyph_len): Now int, not unsigned.
7292 The actual value is always <= INT_MAX, and leaving it unsigned made
7293 overflow checking harder.
7295 * dispextern.h (struct glyph_matrix.rows_allocated)
7296 (struct face_cache.size): Now ptrdiff_t, for convenience in use
7297 with xpalloc. The values are still always <= INT_MAX.

7308 (region_cache_backward, pp_cache):
7309 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
7310 so that ptrdiff_t * can be passed to xpalloc.
7311 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
7312 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.

7330 because xmalloc/xrealloc may not return.
7331 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
7332 now that we have proper integer overflow checking.
7333 (record_overlay_string, overlay_strings): Catch overflows when

7336 * callproc.c (Fcall_process): Check for size overflow when

7340 require adding more-complicated checks.
7342 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
7343 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
7344 Redo buffer-overflow calculations to avoid integer overflow.

7383 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
7385 * emacs.c (main): Do not reallocate argv, since there is a null at
7386 the end that can be overwritten, and this way there's no need to
7387 worry about size-calculation overflow.
7388 (sort_args): Check for size-calculation overflow.
7390 * eval.c (init_eval_once, grow_specpdl): Don't update size until

7396 Check for integer overflow.
7397 (x_set_alpha): Do not assume XINT fits in int.
7399 * frame.h (struct frame): Use int, not EMACS_INT, where int works.

7401 where the system imposes an 'int' limit.
7403 * fringe.c (Fdefine_fringe_bitmap):
7404 Don't update size until alloc works.
7406 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)

7410 Check for size-calculation overflow.
7411 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
7412 do, as we prefer signed integers.

7419 * gtkutil.h: Change prototypes to match the above.
7421 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these

7517 (X_LONG_MIN): New macros.
7518 Use them to make the following changes clearer.
7519 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.

7522 (SELECTION_QUANTUM): Remove, replacing with ...
7523 (selection_quantum): ... new function, which avoids overflow.
7525 (struct selection_data.size): Now ptrdiff_t, not int, to avoid

7543 Don't store size until memory allocation succeeds.
7544 (x_get_window_property): Plug memory leak on memory exhaustion.
7545 Don't double-block input; malloc is safe here. Don't assume 2**34
7546 - 4 fits in unsigned long. Add an xassert to check
7547 XGetWindowProperty overflow. Be more careful about overflow
7548 calculations, and distinguish size from memory overflow better.

7592 * lisp.h (hash_lookup, hash_put):
7593 * minibuf.c (Ftest_completion):
7594 Use ptrdiff_t for hash table indexes, not int (which is too

7635 that is used in the definition.
7636 (read_key_sequence, keyremap_step):
7637 Change bufsize argument back to int, undoing my 2011-03-30 change.

7640 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow

7642 length, not size_t. Use ptrdiff_t for index, not int.
7643 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
7644 possibility of integer overflow.

7672 Prefer int to unsigned where either will do.
7673 (tiff_handler): New function, combining the cores of the
7674 old tiff_error_handler and tiff_warning_handler.

7701 `(space ...)', and specifies display in the text area, return 2
7703 (try_cursor_movement): Check for the need to scroll more
7704 accurately, and prefer exact match for point under bidi.
7705 Don't advance `row' beyond the last row of the window.

7726 positioning on the newline at EOL of R2L text within L2R
7727 paragraph, and vice versa.
7728 (try_cursor_movement): Check continued rows, in addition to
7729 continuation rows. Fixes unwarranted scroll when point enters a
7730 continued line of R2L text within an L2R paragraph, or vice versa.
7731 (cursor_row_p): Consider the case of point being equal to
7732 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
7733 from the end of a short line to the beginning of a continued line
7734 of R2L text within L2R paragraph.
7735 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
7736 composed characters.
7738 * bidi.c (bidi_check_type): Use xassert.
7739 (bidi_cache_iterator_state): Update the disp_pos and disp_prop_p
7742 2011-08-23 Eli Zaretskii <eliz@gnu.org>
7744 * bidi.c (bidi_get_type): Abort if we get zero as the bidi type of

7749 * nsfont.m (ns_otf_to_script): Fix typo.
7751 2011-08-22 Kenichi Handa <handa@m17n.org>
7753 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
7754 extra slot even if the purpose is char-code-property-table.
7756 2011-08-23 Eli Zaretskii <eliz@gnu.org>
7758 * xdisp.c (redisplay_window): When computing centering_position,
7759 account for the height of the header line. (Bug#8874)
7761 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
7762 instead of CHAR_TO_BYTE. Fixes a crash when a completion
7763 candidate is selected by the mouse, and that candidate has a
7764 composed character under the mouse.
7766 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
7767 coordinates reported by pos-visible-in-window-p for a composed
7768 character in column zero.
7770 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
7772 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
7774 2011-08-22 Eli Zaretskii <eliz@gnu.org>
7776 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
7777 consider it a hit if to_charpos is anywhere in the range of the
7778 composed buffer positions.
7780 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
7782 * image.c (gif_load): Don't assume that each subimage has the same
7783 dimensions as the base image. Handle disposal method that is
7784 "undefined" by the gif spec (Bug#9335).
7786 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
7788 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
7789 (Fcondition_case): Document `debug' symbol in error handler.
7791 2011-08-19 Eli Zaretskii <eliz@gnu.org>
7793 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
7794 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
7795 from an Org mode buffer to a Speedbar frame.
7797 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
7798 a composition, take its buffer position from IT->cmp_it.charpos.
7799 Fixes cursor positioning at the beginning of a line that begins
7800 with a composed character.
7802 2011-08-18 Eli Zaretskii <eliz@gnu.org>
7804 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
7805 character bidirectional type, use STRONG_L instead. Fixes crashes
7806 in a buffer produced by `describe-categories'.
7808 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
7809 members before the level stack, so they would be saved and
7810 restored when copying iterator state. Fixes incorrect reordering
7811 around TABs covered by display properties.
7813 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
7815 * process.c (Fnetwork_interface_list): Correctly determine buffer size.
7817 2011-08-17 Chong Yidong <cyd@stupidchicken.com>
7819 * eval.c (internal_condition_case, internal_condition_case_1)
7820 (internal_condition_case_2, internal_condition_case_n):
7821 Remove unnecessary aborts (Bug#9081).
7823 2011-08-17 Eli Zaretskii <eliz@gnu.org>
7825 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
7826 has no `load' handler, try opening the file locally. (Bug#9311)
7828 2011-08-16 Ken Brown <kbrown@cornell.edu>
7830 * gmalloc.c: Expand comment.
7832 2011-08-16 Eli Zaretskii <eliz@gnu.org>

7837 2011-08-16 Ken Brown <kbrown@cornell.edu>
7839 Fix memory allocation problems in Cygwin build (Bug#9273).
7841 * unexcw.c ( __malloc_initialized): Declare external variable.
7842 (fixup_executable): Force the dumped emacs to reinitialize malloc.
7844 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):
7846 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the
7848 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
7850 [CYGWIN] (special_realloc): New function.
7851 (_realloc_internal_nolock) [CYGWIN]: Use the new function on
7852 requests to realloc storage in the static heap.
7854 2011-08-15 Paul Eggert <eggert@cs.ucla.edu>
7856 * bidi.c (bidi_initialize): Remove unused local.
7858 2011-08-15 Eli Zaretskii <eliz@gnu.org>
7861 * biditype.h: Remove file.
7862 * makefile.w32-in ($(BLD)/bidi.$(O)):

7867 * chartab.c: Improve commentary for the uniprop_table API.
7869 * bidi.c (bidi_paragraph_init): Support zero value of
7870 bidi_ignore_explicit_marks_for_paragraph_level.
7871 (bidi_initialize): Use uniprop_table instead of including
7872 biditype.h and bidimirror.h.
7874 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
7875 coordinates of the iterator when restoring from ppos_it.
7878 2011-08-14 Kenichi Handa <handa@m17n.org>
7880 * process.c (create_process): Call setup_process_coding_systems
7881 after the pid of the process is set to -1 (Bug#8162).
7883 2011-08-14 Eli Zaretskii <eliz@gnu.org>
7885 * xdisp.c (move_it_in_display_line_to): Don't invoke
7886 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
7887 ppos_it. Fixes vertical cursor motion when line beginning is
7888 covered by an image. (Bug#9296)
7890 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
7892 * nsterm.h (ns_run_ascript): Declare.
7893 (NSAPP_DATA2_RUNASSCRIPT): Define.
7895 * nsfns.m (as_script, as_result, as_status): New static variables.
7896 (ns_run_ascript): New function.
7897 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
7898 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
7899 the event loop. Get status from as_status (Bug#7276).
7901 * nsterm.m (sendEvent): If event is NSApplicationDefined and
7902 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
7903 the event loop (Bug#7276).
7905 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
7907 * gnutls.c (QCgnutls_bootprop_priority)
7908 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
7909 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
7910 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
7911 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
7912 (QCgnutls_bootprop_verify_hostname_error)
7913 (QCgnutls_bootprop_callbacks_verify): Rename from
7914 Qgnutls_bootprop_..., all uses changed.

7922 * dispextern.h (Qframe_set_background_mode): Remove decl.
7924 * process.c (Fnetwork_interface_info): Declare local only if needed.
7926 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
7928 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
7929 (Fnetwork_interface_list): Allocate in increments of bytes instead
7930 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
7931 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
7933 (struct ifflag_def): notrailers is smart on OSX.
7934 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
7935 Get hardware address with getifaddrs if available.
7937 2011-08-12 Eli Zaretskii <eliz@gnu.org>
7939 * xdisp.c (iterate_out_of_display_property): xassert that
7940 IT->position is set to within IT->object's boundaries. Break from
7941 the loop as soon as EOB is reached; avoids infloops in redisplay
7942 when IT->position is set up wrongly due to some bug.
7943 Set IT->current to match the bidi iterator unconditionally.
7944 (push_display_prop): Allow GET_FROM_STRING as IT->method on
7945 entry. Force push_it to save on the stack the current
7946 buffer/string position, to be restored by pop_it. Fix flags in
7947 the iterator structure wrt the object coming from a display
7948 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
7949 properties. (Bug#9284)
7951 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
7953 * fontset.c (fontset_get_font_group): Add proper type checks.

7961 (dump_it) [LC_FUNCTION_STARTS]: Use it.
7963 2011-08-08 Eli Zaretskii <eliz@gnu.org>
7965 * xdisp.c (forward_to_next_line_start): Allow to use the
7966 no-display-properties-and-no-overlays under bidi display.
7967 Set disp_pos in the bidi iterator to avoid searches for display
7968 properties and overlays.
7970 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
7972 * editfns.c (Fset_time_zone_rule): Document relationship with the
7975 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
7976 the font entity extracted from the cache (Bug#8109).
7978 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
7980 * composite.c (autocmp_chars): Don't reset point. That is done by
7981 restore_point_unwind (Bug#5984).
7983 2011-08-07 Juri Linkov <juri@jurta.org>
7985 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
7986 to show the arg `TIME' instead of `TIMEVAL'.
7988 2011-08-06 Eli Zaretskii <eliz@gnu.org>
7990 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
7991 display property strides EOL and includes a newline, as in
7992 longlines-mode. (Bug#9254)
7993 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
7994 word-wrap under bidirectional display. (Bug#9224)
7996 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
7997 is non-zero, even if the data buffer is NULL. Fixes a crash in
7998 vertical-motion with longlines-mode. (Bug#9254)
8000 2011-08-05 Eli Zaretskii <eliz@gnu.org>
8002 * bidi.c <bidi_cache_total_alloc>: Now static.
8003 (bidi_initialize): Initialize bidi_cache_total_alloc.
8005 * xdisp.c (display_line): Release buffer allocated for shelved bidi
8008 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
8009 amount allocated this far in `bidi_cache_total_alloc'.
8010 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
8011 non-zero, only free the data buffer without restoring the cache
8012 contents. All callers changed.
8014 * dispextern.h (bidi_unshelve_cache): Update prototype.
8016 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
8017 (move_it_in_display_line, move_it_to)
8018 (move_it_vertically_backward, move_it_by_lines): Replace the call
8019 to xfree to an equivalent call to bidi_unshelve_cache.
8020 (move_it_in_display_line_to): Fix logic of returning
8021 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
8023 2011-08-05 Eli Zaretskii <eliz@gnu.org>
8025 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
8026 came from a string character with a `cursor' property. (Bug#9229)
8028 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
8030 * Makefile.in (LIB_PTHREAD): New variable.
8031 (LIBES): Add LIB_PTHREAD (Bug#9216).
8033 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
8034 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
8036 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
8038 * regex.c (re_iswctype): Remove some redundant boolean conversions.
8040 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
8042 * xterm.c (x_find_topmost_parent): New function.
8043 (x_set_frame_alpha): Find topmost parent window with
8044 x_find_topmost_parent and set the property there also (bug#9181).

8054 * keymap.c (Fmake_composed_keymap): Move to subr.el.
8056 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
8058 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
8059 so that it is not optimized away.
8061 * xdisp.c (compute_display_string_pos): Remove unused local.
8063 2011-08-02 Eli Zaretskii <eliz@gnu.org>
8065 Fix slow cursor motion and scrolling in large buffers with
8066 selective display, like Org Mode buffers. (Bug#9218)
8068 * dispextern.h (struct bidi_it): New member disp_prop_p.
8070 * xdisp.c: Remove one-slot cache of display string positions.
8071 (compute_display_string_pos): Accept an additional argument
8072 DISP_PROP_P; callers changed. Scan at most 5K characters forward
8073 for a display string or property. If found, set DISP_PROP_P
8076 * bidi.c (bidi_fetch_char): Accept an additional argument
8077 DISP_PROP_P, and pass it to compute_display_string_pos.
8078 Only handle text covered by a display string if DISP_PROP_P is returned
8079 non-zero. All callers of bidi_fetch_char changed.
8081 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
8083 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
8085 2010-12-03 Don March <don@ohspite.net>

8088 last character M-[char] is translated to ESC [char] (bug#7541).
8090 2011-08-02 Kenichi Handa <handa@m17n.org>
8092 * lisp.h (uniprop_table): Extern it.
8094 * chartab.c (uniprop_table): Make it non-static.
8096 2011-08-01 Eli Zaretskii <eliz@gnu.org>
8098 * xdisp.c (forward_to_next_line_start): Accept additional argument
8099 BIDI_IT_PREV, and store into it the state of the bidi iterator had
8101 (reseat_at_next_visible_line_start): Use the bidi iterator state
8102 returned by forward_to_next_line_start to restore the state of
8103 it->bidi_it after backing up to previous newline. (Bug#9212)
8105 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
8107 * regex.c (re_comp): Protoize.
8108 (re_exec): Fix return type.

8113 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
8114 This is needed if max-image-size is a floating-point number.
8116 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8118 * print.c (print_object): Print empty symbol as ##.
8120 * lread.c (read1): Read ## as empty symbol.
8122 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8124 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
8125 setting frame foreground color (Bug#9175).
8126 (x_set_background_color): Likewise.
8128 * nsmenu.m (-setText): Size tooltip dimensions precisely to
8129 contents (Bug#9176).
8130 (EmacsTooltip -init): Remove bezels and add shadows to
8133 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
8134 or scroll bar (Bug#8470).
8136 * nsfont.m (nsfont_open): Remove assignment to voffset and
8137 unnecessary vars hshink, expand, hd, full_height, min_height.

8142 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8144 Implement strike-through and overline on NextStep (Bug#8863).
8146 * nsfont.m (nsfont_open): Use underline position provided by font,
8147 instead of hard-coded value of 2.
8148 (nsfont_draw): Call ns_draw_text_decoration instead.

8160 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
8163 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8165 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
8166 Without this fix, if a signal arrives just after memory fills up,
8167 'malloc' might be invoked reentrantly.
8169 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
8170 In other words, assume that every image size is allowed, on non-X
8171 hosts. This assumption is probably wrong, but it lets Emacs compile.
8173 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8175 * regex.c (re_iswctype): Convert return values to boolean.
8177 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
8179 * xdisp.c (compute_display_string_pos): Don't use cached display
8180 string position if the buffer had its restriction changed.

8191 * bidi.c: Integer size and overflow fixes.
8192 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
8193 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
8194 (bidi_cache_find_level_change, bidi_cache_ensure_space)
8195 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
8196 (bidi_find_other_level_edge):
8197 Use ptrdiff_t instead of EMACS_INT where either will do.
8198 This works better on 32-bit hosts configured --with-wide-int.
8199 (bidi_cache_ensure_space): Check for size-calculation overflow.
8200 Use % rather than repeated addition, for better worst-case speed.
8201 Don't set bidi_cache_size until after xrealloc returns, because it
8203 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
8204 (bidi_cache_ensure_space): Also check that the bidi cache size
8205 does not exceed that of the largest Lisp string or buffer. See Eli
8206 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
8208 * alloc.c (__malloc_size_t): Remove.
8209 All uses replaced by size_t. See Andreas Schwab's note
8210 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
8212 * image.c: Improve checking for integer overflow.
8213 (check_image_size): Assume that f is nonnull, since
8214 it is always nonnull in practice. This is one less thing to
8215 worry about when checking for integer overflow later.
8216 (x_check_image_size): New function, which checks for integer
8217 overflow issues inside X.
8218 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
8219 This removes the need for a memory_full check.
8220 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
8221 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
8222 (xbm_read_bitmap_data): Change locals back to 'int', since
8223 their values must fit in 'int'.
8224 (xpm_load_image, png_load, tiff_load):
8225 Invoke x_create_x_image_and_pixmap earlier,
8226 to avoid much needless work if the image is too large.
8227 (tiff_load): Treat overly large images as if
8228 x_create_x_image_and_pixmap failed, not as malloc failures.
8229 (gs_load): Use x_check_image_size.
8231 * gtkutil.c: Omit integer casts.
8232 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
8233 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
8235 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
8237 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
8238 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
8239 would wrongly return t on a 64-bit host.
8241 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
8242 The plain *_OVERFLOW macros run afoul of GCC bug 49705
8243 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
8244 and therefore cause GCC to emit a bogus diagnostic in some cases.
8246 * image.c: Integer signedness and overflow and related fixes.
8247 This is not an exhaustive set of fixes, but it's time to
8248 record what I've got.
8249 (lookup_pixel_color, check_image_size): Remove redundant decls.
8250 (check_image_size): Don't assume that arbitrary EMACS_INT values
8251 fit in 'int', or that arbitrary 'double' values fit in 'int'.
8252 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
8253 (tiff_load, imagemagick_load_image):
8254 Check for overflow in size calculations.
8255 (x_create_x_image_and_pixmap): Remove unnecessary test for
8256 xmalloc returning NULL; that can't happen.
8257 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
8258 (xpm_color_bucket): Use better integer hashing function.
8259 (xpm_cache_color): Don't possibly over-allocate memory.
8260 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
8261 (gif_memory_source):
8262 Use ptrdiff_t, not int or size_t, to record sizes.
8263 (png_load): Don't assume values greater than 2**31 fit in 'int'.
8264 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
8265 either works, as we prefer signed integers.
8266 (tiff_read_from_memory, tiff_write_from_memory):
8267 Return tsize_t, not size_t, since that's what the TIFF API wants.
8268 (tiff_read_from_memory): Don't fail simply because the read would
8269 go past EOF; instead, return a short read.
8270 (tiff_load): Omit no-longer-needed casts.
8271 (Fimagemagick_types): Don't assume size fits into 'int'.
8273 Improve hashing quality when configured --with-wide-int.
8274 * fns.c (hash_string): New function, taken from sxhash_string.
8275 Do not discard information about ASCII character case; this
8276 discarding is no longer needed.
8277 (sxhash-string): Use it. Change sig to match it. Caller changed.
8278 * lisp.h: Declare it.
8279 * lread.c (hash_string): Remove, since we now use fns.c's version.
8280 The fns.c version returns a wider integer if --with-wide-int is
8281 specified, so this should help the quality of the hashing a bit.
8283 * emacs.c: Integer overflow minor fix.
8284 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
8285 Define only if GNU_LINUX.
8286 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
8288 * dispnew.c: Integer signedness and overflow fixes.
8289 Remove unnecessary forward decls, that were a maintenance hassle.
8290 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
8292 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
8293 (scrolling_window): Use ptrdiff_t, not int, for byte count.
8294 (prepare_desired_row, line_draw_cost):
8295 Use int, not unsigned, where either works.
8296 (save_current_matrix, restore_current_matrix):
8297 Use ptrdiff_t, not size_t, where either works.
8298 (init_display): Check for overflow more accurately, and without
8299 relying on undefined behavior.
8301 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
8302 Remove, replacing with the new symbols in lisp.h. All uses changed.
8303 * fileio.c (make_temp_name):
8304 * filelock.c (lock_file_1, lock_file):
8305 * xdisp.c (message_dolog):
8306 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
8307 Use pMd etc. instead.
8308 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
8309 replacing the pWIDE etc. symbols removed from editfns.c.
8311 * keyboard.h (num_input_events): Now uintmax_t.
8312 This is (very slightly) less likely to mess up due to wraparound.
8315 * buffer.c: Integer signedness fixes.
8316 (alloc_buffer_text, enlarge_buffer_text):
8317 Use ptrdiff_t rather than size_t when either will do, as we prefer
8320 * alloc.c: Integer signedness and overflow fixes.
8321 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
8322 (__malloc_size_t): Default to size_t, not to int.
8323 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
8324 (Fgarbage_collect, mark_object_loop_halt, mark_object):
8325 Prefer ptrdiff_t to size_t when either would do, as we prefer
8327 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
8328 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
8329 Now const. Initialize with values that are in range even if char
8331 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
8332 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
8333 These functions do the right thing with sizes > 2**32.
8334 (check_depth): Now ptrdiff_t, not int.
8335 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
8336 Adjust to new way of storing sizes. Check for size overflow bugs
8338 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
8339 slightly wrong anyway, as it missed one instance of
8340 XMALLOC_OVERRUN_CHECK_OVERHEAD.
8341 (refill_memory_reserve): Omit needless cast to size_t.
8342 (mark_object_loop_halt): Mark as externally visible.
8344 * xselect.c: Integer signedness and overflow fixes.
8345 (Fx_register_dnd_atom, x_handle_dnd_message):
8346 Use ptrdiff_t, not size_t, since we prefer signed.
8347 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
8348 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
8349 x_dnd_atoms_size and x_dnd_atoms_length.
8351 * doprnt.c: Prefer signed to unsigned when either works.
8353 * doprnt.c (doprnt):
8355 * xdisp.c (vmessage):
8356 Use ptrdiff_t, not size_t, when using or implementing doprnt,
8357 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
8358 prefer signed arithmetic to avoid comparison confusion.
8359 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
8360 but is a bit tricky.
8362 Assume freestanding C89 headers, string.h, stdlib.h.
8363 * data.c, doprnt.c, floatfns.c, print.c:
8364 Include float.h unconditionally.
8365 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
8366 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
8367 * regex.c: Likewise for stddef.h, string.h.
8368 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
8369 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
8370 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
8371 (STDC_HEADERS): Remove obsolete defines.
8372 * sysdep.c: Include limits.h unconditionally.
8374 Assume support for memcmp, memcpy, memmove, memset.
8375 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
8376 * regex.c (memcmp, memcpy):
8377 Remove; we assume C89 now.
8379 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
8380 (__malloc_safe_bcopy): Remove; no longer needed.
8382 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
8383 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
8384 well either way, and we prefer signed to unsigned.
8386 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
8388 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
8389 closes the connection while we're reading (bug#9182).
8391 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
8393 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
8394 are specified (Bug#9168).
8396 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
8398 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
8399 Found by GCC static checking and --with-wide-int on a 32-bit host.
8401 2011-07-25 Eli Zaretskii <eliz@gnu.org>
8403 * xdisp.c (compute_display_string_pos): Fix logic of caching
8404 previous display string position. Initialize cached_prev_pos to
8405 -1. Fixes slow-down at the beginning of a buffer.
8407 2011-07-24 Eli Zaretskii <eliz@gnu.org>
8409 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
8410 for attrs[LFACE_FONTSET_INDEX].
8412 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
8414 * xml.c (parse_region): Remove unused local
8415 that was recently introduced.
8417 2011-07-23 Eli Zaretskii <eliz@gnu.org>
8419 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
8420 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
8422 * xdisp.c (move_it_in_display_line_to): Record the best matching
8423 position for TO_CHARPOS while scanning the line, and restore it on
8424 exit if none of the characters scanned was an exact match.
8425 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
8426 when exact match is impossible due to invisible text, and the
8427 lines are truncated.
8429 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
8431 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
8434 2011-07-22 Eli Zaretskii <eliz@gnu.org>
8436 Fix a significant slow-down of cursor motion with C-n, C-p,
8437 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
8438 auto-repeat under bidi redisplay in fontified buffers.
8439 * xdisp.c (compute_stop_pos_backwards): New function.
8440 (next_element_from_buffer): Call compute_stop_pos_backwards to
8441 find a suitable prev_stop when we find ourselves before
8443 (reseat): Don't look for prev_stop, as that could mean a very long
8445 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
8446 <cached_disp_overlay_modiff>: Cache for last found display string
8448 (compute_display_string_pos): Return the cached position if asked
8449 about the same buffer in the same area of character positions, and
8450 the buffer wasn't changed since the time the display string
8451 position was cached.
8453 2011-07-22 Eli Zaretskii <eliz@gnu.org>
8455 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
8456 is an integer, which is important for empty lines. (Bug#9149)
8458 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
8460 * frame.c (Fmodify_frame_parameters): In tty case, update the
8461 default face if necessary (Bug#4238).
8463 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
8465 * editfns.c (Fstring_to_char): No need to explain what a character
8466 is in the docstring (Bug#6576).
8468 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
8470 * xml.c (parse_region): Make sure we always return a tree.
8472 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
8474 * xml.c (parse_region): If a document contains only comments,
8477 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
8479 * xml.c (make_dom): Return comments, too.
8481 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
8484 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
8485 and the surrounding thread.
8486 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
8487 rather than fgets, and retry after EINTR. Otherwise, 'emacs
8488 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
8490 * s/openbsd.h (BROKEN_SIGIO): Define.
8491 * unexelf.c (unexec) [__OpenBSD__]:
8492 Don't update the .mdebug section of the Alpha COFF symbol table.
8494 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
8496 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
8499 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
8501 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
8502 This fixes some race conditions on the permissions of any newly
8505 * alloc.c (valid_pointer_p): Use pipe, not open.
8506 This fixes some permissions issues when debugging.
8508 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
8509 If fchown fails to set both uid and gid, try to set just gid,
8510 as that is sometimes allowed. Adjust the file's mode to eliminate
8511 setuid or setgid bits that are inappropriate if fchown fails.
8513 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
8515 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
8516 to compare Lisp_Objects.
8517 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
8518 global_gnutls_log_level, don't mistake it for a Lisp_Object.
8519 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
8521 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
8523 * lread.c (read_integer): Unread even EOF character.
8524 (read1): Likewise. Properly record start position of symbol.
8526 * lread.c (read1): Read `#:' as empty uninterned symbol if no
8527 symbol character follows.
8529 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
8531 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
8532 This works around a problem with the previous change to Fcopy_file.
8533 Recent glibc declares fchown with __attribute__((warn_unused_result)),
8534 and without this change, GCC might complain about discarding
8535 fchown's return value.
8537 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
8539 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
8541 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
8543 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
8545 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
8547 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
8548 it's used from the C level.
8550 * process.c: Use the same condition for POLL_FOR_INPUT in both
8551 keyboard.c and process.c (bug#1858).
8553 2011-07-09 Lawrence Mitchell <wence@gmx.li>
8555 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
8556 (Fgnutls_boot): Use it.
8558 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
8560 * doc.c (Fsubstitute_command_keys): Revert last change.
8562 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
8564 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
8565 quotes the next character, and doesn't affect other longer
8566 sequences (bug#8935).
8568 * lread.c (syms_of_lread): Clarify that is isn't only
8569 `eval-buffer' and `eval-defun' that's affected by
8570 `lexical-binding' (bug#8460).
8572 2011-07-15 Eli Zaretskii <eliz@gnu.org>
8574 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
8575 bidi redisplay when a line includes both an image and is truncated.
8577 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
8579 Fix minor problems found by static checking.
8580 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
8581 (elsz): Now a signed constant, not a size_t var. We prefer signed
8582 types to unsigned, to avoid integer comparison confusion. Without
8583 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
8584 "cannot optimize loop, the loop counter may overflow", a symptom
8586 * indent.c (Fvertical_motion): Mark locals as initialized.
8587 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
8589 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
8591 * search.c (Fre_search_backward): Mention `case-fold-search' in
8592 all the re_search_* functions (bug#8138).
8594 * keyboard.c (Fopen_dribble_file): Document when the file is
8597 2011-07-14 Eli Zaretskii <eliz@gnu.org>
8599 * bidi.c (bidi_dump_cached_states): Fix format of displaying
8602 Support bidi reordering of display and overlay strings.
8603 * xdisp.c (compute_display_string_pos)
8604 (compute_display_string_end): Accept additional argument STRING.
8605 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
8606 (reseat_to_string): Initialize bidi_it->string.s and
8607 bidi_it->string.schars.
8608 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
8609 NULL (avoids a crash in bidi_paragraph_init).
8610 Initialize itb.string.lstring.
8611 (init_iterator): Call bidi_init_it only of a valid
8612 buffer position was specified. Initialize paragraph_embedding to
8614 (reseat_to_string): Initialize the bidi iterator.
8615 (display_string): If we need to ignore text properties of
8616 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
8617 original value of -1 will not work with bidi.)
8618 (compute_display_string_pos): First arg is now struct
8619 `text_pos *'; all callers changed. Support display properties on
8621 (compute_display_string_end): Support display properties on Lisp
8623 (init_iterator, reseat_1, reseat_to_string): Initialize the
8624 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
8625 when iterating on a string not from display properties).
8626 (compute_display_string_pos, compute_display_string_end):
8627 Fix calculation of the object to scan. Fixes an error when using
8629 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
8630 base_level_stop; instead, set base_level_stop to BEGV.
8631 Fixes crashes in vertical-motion.
8632 (next_element_from_buffer): Improve commentary for when
8633 the iterator is before prev_stop.
8634 (init_iterator): Initialize bidi_p from the default value of
8635 bidi-display-reordering, not from buffer-local value. Use the
8636 buffer-local value only if initializing for buffer iteration.
8637 (handle_invisible_prop): Support invisible properties on strings
8638 that are being bidi-reordered.
8639 (set_iterator_to_next): Support bidi reordering of C strings and
8641 (next_element_from_string): Support bidi reordering of Lisp
8643 (handle_stop_backwards): Support Lisp strings as well.
8644 (display_string): Support display of R2L glyph rows.
8645 Use IT_STRING_CHARPOS when displaying from a Lisp string.
8646 (init_iterator): Don't initialize it->bidi_p for strings
8648 (reseat_to_string): Initialize it->bidi_p for strings here.
8649 (next_element_from_string, next_element_from_c_string)
8650 (next_element_from_buffer): Add xassert's for correspondence
8651 between IT's object being iterated and it->bidi_it.string
8653 (face_before_or_after_it_pos): Support bidi iteration.
8654 (next_element_from_c_string): Handle the case of the first string
8655 character that is not the first one in the visual order.
8656 (get_visually_first_element): New function, refactored from common
8657 parts of next_element_from_buffer, next_element_from_string, and
8658 next_element_from_c_string.
8659 (tool_bar_lines_needed, redisplay_tool_bar)
8660 (display_menu_bar): Force left-to-right direction. Add a FIXME
8661 comment for making that be controlled by a user option.
8662 (push_it, pop_it): Save and restore the state of the
8663 bidi iterator. Save and restore the bidi_p flag.
8664 (pop_it): Iterate out of display property for string iteration as
8666 (iterate_out_of_display_property): Support iteration over strings.
8667 (handle_single_display_spec): Set up it->bidi_it for iteration
8668 over a display string, and call bidi_init_it.
8669 (handle_single_display_spec, next_overlay_string)
8670 (get_overlay_strings_1, push_display_prop): Set up the bidi
8671 iterator for displaying display or overlay strings.
8672 (forward_to_next_line_start): Don't use the shortcut if
8674 (back_to_previous_visible_line_start): If handle_display_prop
8675 pushed the iterator stack, restore the internal state of the bidi
8676 iterator by calling bidi_pop_it same number of times.
8677 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,

9150 2011-07-05 Paul Eggert <eggert@cs.ucla.edu>
9152 Random fixes. E.g., (random) never returned negative values.
9153 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
9154 subseconds part to the entropy, as that's a bit more random.
9155 Prefer signed to unsigned, since the signedness doesn't matter and
9156 in general we prefer signed. When given a limit, use a
9157 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
9158 latter isn't right if USE_2_TAGS_FOR_INTS.
9159 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
9160 not 0..VALMASK. Don't discard "excess" bits that random () returns.
9162 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>

9170 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
9172 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
9173 This is more efficient than Ffile_directory_p and avoids a minor race.
9175 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
9177 * buffer.c (Foverlay_put): Say what the return value is
9180 * fileio.c (barf_or_query_if_file_exists): Check first if the file
9181 is a directory before asking whether to use the file name
9183 (barf_or_query_if_file_exists): Make the "File is a directory"
9184 error be more correct.
9186 * fns.c (Frequire): Remove the mention of the .gz files, since
9187 that's installation-specific, but keep the mention of
9188 `get-load-suffixes'.
9190 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
9192 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

9200 Qgnutls_bootprop_verify_error (which is no longer used).
9202 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
9203 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
9204 Also (re)move comments that are misplaced or no longer relevant.
9206 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
9208 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

9239 2011-07-02 Martin Rudalics <rudalics@gmx.at>
9241 * window.h (window): Remove clone_number slot.

9300 (wait_reading_process_output): Add defined (HAVE_GSETTINGS) for
9303 2011-07-01 Paul Eggert <eggert@cs.ucla.edu>
9305 * eval.c (struct backtrace): Simplify and port the data structure.
9306 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
9307 signed bit field, as this assumption is not portable and it makes
9308 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
9309 "char debug_on_exit : 1" as this is not portable either; instead,
9310 use the portable "unsigned int debug_on_exit : 1". Remove unused
9311 member evalargs. Remove obsolete comments about cc bombing out.
9313 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

9475 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
9477 Integer and buffer overflow fixes (Bug#8873).
9479 * print.c (printchar, strout): Check for string overflow.
9480 (PRINTPREPARE, printchar, strout):
9481 Don't set size unless allocation succeeds.
9483 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,

9502 read-circle numbers.
9503 (read_escape): Avoid int overflow.
9504 (Fload, openp, read_buffer_size, read1)
9505 (substitute_object_recurse, read_vector, read_list, map_obarray):

9526 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
9528 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
9529 The following patches are for when GLYPH_DEBUG && !XASSERT.
9530 * dispextern.h (trace_redisplay_p, dump_glyph_string):
9531 * dispnew.c (flush_stdout):
9532 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
9533 Mark as externally visible.
9534 * dispnew.c (check_window_matrix_pointers): Now static.
9535 * dispnew.c (window_to_frame_vpos):
9536 * xfns.c (unwind_create_frame):

9542 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
9543 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
9545 (debug_method_add): Use va_list and vsprintf rather than relying
9546 on undefined behavior with wrong number of arguments.
9547 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
9548 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
9549 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
9550 since we're not interested in debugging glyphs with old libraries.
9551 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
9552 GCC 4.6.0's static checking.
9554 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
9556 Integer overflow and signedness fixes (Bug#8873).

9586 (Fnext_overlay_change, Fprevious_overlay_change)
9587 (mouse_face_overlay_overlaps, Foverlays_in):
9588 Use ptrdiff_t, not int, for sizes.
9589 (overlays_at, overlays_in): Check for size-calculation overflow.
9591 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
9593 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
9594 (x_session_initialize): Do not assume string length fits in int.
9596 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
9597 This is unlikely, but can occur if DPI is outlandish.
9599 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
9600 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
9602 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
9603 * xrdb.c (magic_file_p, search_magic_path):
9604 Omit last arg SUFFIX; it was always 0. All callers changed.
9605 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
9607 * xfont.c (xfont_match): Avoid need for strlen.
9609 * xfns.c: Don't assume strlen fits in int.
9610 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
9612 * xdisp.c (message_log_check_duplicate): Return intmax_t,
9613 not unsigned long, as we prefer signed integers. All callers changed.
9614 Detect integer overflow in repeat count.
9615 (message_dolog): Don't assume print length fits in 39 bytes.
9616 (display_mode_element): Don't assume strlen fits in int.
9618 * termcap.c: Don't assume sizes fit in int and never overflow.
9619 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
9620 (gobble_line): Check for size-calculation overflow.
9622 * minibuf.c (Fread_buffer):
9623 * lread.c (intern, intern_c_string):
9624 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
9625 Don't assume string length fits in int.
9627 * keyboard.c (parse_tool_bar_item):
9628 * gtkutil.c (style_changed_cb): Avoid need for strlen.
9630 * font.c: Don't assume string length fits in int.
9631 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
9632 Use ptrdiff_t, not int.
9633 (font_intern_prop): Don't assume string length fits in int.
9634 Don't assume integer property fits in fixnum.
9635 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
9637 * filelock.c: Fix some buffer overrun and integer overflow issues.
9638 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
9639 Reformulate so as not to need the command string.
9640 Invoke gzip -cd rather than gunzip, as it's more portable.
9641 (lock_info_type, lock_file_1, lock_file):
9642 Don't assume pid_t and time_t fit in unsigned long.
9643 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
9644 (current_lock_owner): Prefer signed type for sizes.
9645 Use memcpy, not strncpy, where memcpy is what is really wanted.
9646 Don't assume (via atoi) that time_t and pid_t fit in int.
9647 Check for time_t and/or pid_t out of range, e.g., via a network share.
9648 Don't alloca where an auto var works fine.
9650 * fileio.c: Fix some integer overflow issues.
9651 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
9652 Don't assume string length fits in int.
9653 (directory_file_name): Don't assume string length fits in long.
9654 (make_temp_name): Don't assume pid fits in int, or that its print
9655 length is less than 20.
9657 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
9659 * coding.c (make_subsidiaries): Don't assume string length fits in int.
9661 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
9663 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
9664 We prefer signed integers, even for size calculations.
9666 * emacs.c: Don't assume string length fits in 'int'.
9667 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
9668 (main): Don't invoke strlen when not needed.
9670 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
9671 (XD_DEBUG_MESSAGE): Don't waste a byte.
9673 * callproc.c (getenv_internal_1, getenv_internal)
9675 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
9677 * lread.c (invalid_syntax): Omit length argument.
9678 All uses changed. This doesn't fix a bug, but it simplifies the
9679 code away from its former Hollerith-constant appearance, and it's
9680 one less 'int' to worry about when looking at integer-overflow issues.
9681 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
9683 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
9684 This didn't break anything, but it didn't help either.
9685 It's confusing to put a bogus integer in a place where the actual
9686 value does not matter.
9687 (LIST_END_P): Remove unused macro and its bogus comment.
9688 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
9690 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
9691 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
9693 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
9694 We prefer signed types, and the value cannot exceed the EMACS_INT
9695 range anyway (because otherwise the length would not be representable).
9696 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
9697 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
9698 This avoids a GCC warning when WIDE_EMACS_INT.
9700 * indent.c (sane_tab_width): New function.
9701 (current_column, scan_for_column, Findent_to, position_indentation)
9702 (compute_motion): Use it. This is just for clarity.
9703 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
9705 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
9707 * lisp.h (lint_assume): New macro.
9708 * composite.c (composition_gstring_put_cache):
9709 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
9711 * editfns.c, insdel.c:
9712 Omit unnecessary forward decls, to simplify future changes.
9714 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
9716 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
9718 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
9719 Use much-faster test for byte-length change.
9720 Don't assume string byte-length fits in 'int'.
9721 Check that character arg fits in 'int'.
9722 (mapcar1): Declare byte as byte, for clarity.
9724 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
9726 * fns.c (concat): Catch string overflow earlier.
9727 Do not rely on integer wraparound.
9729 * dispextern.h (struct it.overlay_strings_charpos)
9730 (struct it.selective): Now EMACS_INT, not int.
9731 * xdisp.c (forward_to_next_line_start)
9732 (back_to_previous_visible_line_start)
9733 (reseat_at_next_visible_line_start, next_element_from_buffer):
9734 Don't arbitrarily truncate the value of 'selective' to int.
9736 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
9738 * composite.c: Don't truncate sizes to 'int'.
9739 (composition_gstring_p, composition_reseat_it)
9740 (composition_adjust_point): Use EMACS_INT, not int.
9741 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
9742 not EMACS_UINT, for indexes.
9744 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
9746 * buffer.c: Include <verify.h>.
9747 (struct sortvec.priority, struct sortstr.priority):
9748 Now EMACS_INT, not int.
9749 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
9750 (struct sortstr.size, record_overlay_string)
9751 (struct sortstrlist.size, struct sortlist.used):
9752 Don't truncate size to int.
9753 (record_overlay_string): Check for size-calculation overflow.
9754 (init_buffer_once): Check at compile-time, not run-time.
9756 2011-06-22 Jim Meyering <meyering@redhat.com>
9758 Don't leak an XBM-image-sized buffer
9759 * image.c (xbm_load): Free the image buffer after using it.
9761 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
9764 * composite.c (find_automatic_composition): Omit needless 'return 0;'
9765 that Sun C diagnosed.
9766 * fns.c (secure_hash): Fix pointer signedness issue.
9767 * intervals.c (static_offset_intervals): New function.
9768 (offset_intervals): Use it.
9770 2011-06-21 Leo Liu <sdl.web@gmail.com>
9773 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
9776 * fns.c (secure_hash): Rename from crypto_hash_function and change
9777 the first arg to accept symbols.
9778 (Fsecure_hash): New primitive.
9779 (syms_of_fns): New symbols.
9781 2011-06-20 Deniz Dogan <deniz@dogan.se>
9783 * process.c (Fset_process_buffer): Clarify return value in
9786 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
9788 * dispnew.c (add_window_display_history): Use BVAR.
9790 * xdisp.c (debug_method_add): Use BVAR.
9791 (check_window_end, dump_glyph_matrix, dump_glyph)
9792 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
9794 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
9797 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
9798 check till after the cache is created in init_frame_faces.
9800 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
9802 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
9804 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
9806 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
9807 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
9808 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
9810 Improve buffer-overflow checking (Bug#8873).
9811 * fileio.c (Finsert_file_contents):
9812 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
9813 Remove the old (too-loose) buffer overflow checks.
9814 They weren't needed, since make_gap checks for buffer overflow.
9815 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
9816 The old code merely checked for Emacs fixnum overflow, and relied
9817 on undefined (wraparound) behavior. The new code avoids undefined
9818 behavior, and also checks for ptrdiff_t and/or size_t overflow.
9820 * editfns.c (Finsert_char): Don't dump core with very negative counts.
9821 Tune. Don't use wider integers than needed. Don't use alloca.
9822 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
9824 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
9826 * insdel.c, lisp.h (buffer_overflow): New function.
9827 (insert_from_buffer_1, replace_range, replace_range_2):
9828 * insdel.c (make_gap_larger):
9829 * editfns.c (Finsert_char):
9830 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
9832 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
9834 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
9836 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
9838 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
9839 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
9841 * fileio.c: Don't assume EMACS_INT fits in off_t.
9842 (emacs_lseek): New static function.
9843 (Finsert_file_contents, Fwrite_region): Use it.
9844 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
9846 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
9848 * fns.c: Don't overflow int when computing a list length.
9849 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
9850 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
9851 truncation on 64-bit hosts. Check for QUIT every
9852 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
9853 faster and is responsive enough.
9854 (Flength): Report an error instead of overflowing an integer.
9855 (Fsafe_length): Return a float if the value is not representable
9856 as a fixnum. This shouldn't happen except in contrived situations.
9857 (Fnthcdr, Fsort): Don't assume list length fits in int.
9858 (Fcopy_sequence): Don't assume vector length fits in int.
9860 * alloc.c: Check that resized vectors' lengths fit in fixnums.
9861 (header_size, word_size): New constants.
9862 (allocate_vectorlike): Don't check size overflow here.
9863 (allocate_vector): Check it here instead, since this is the only
9864 caller of allocate_vectorlike that could cause overflow.
9865 Check that the new vector's length is representable as a fixnum.
9867 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
9868 The previous code was bogus. For example, next_almost_prime (32)
9869 returned 39, which is undesirable as it is a multiple of 3; and
9870 next_almost_prime (24) returned 25, which is a multiple of 5 so
9871 why was the code bothering to check for multiples of 7?
9873 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
9875 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
9877 Variadic C functions now count arguments with ptrdiff_t.
9878 This partly undoes my 2011-03-30 change, which replaced int with size_t.
9879 Back then I didn't know that the Emacs coding style prefers signed int.
9880 Also, in the meantime I found a few more instances where arguments
9881 were being counted with int, which may truncate counts on 64-bit
9882 machines, or EMACS_INT, which may be unnecessarily wide.
9883 * lisp.h (struct Lisp_Subr.function.aMANY)
9884 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
9885 Arg counts are now ptrdiff_t, not size_t.
9886 All variadic functions and their callers changed accordingly.
9887 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
9888 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
9889 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
9890 * callint.c (Fcall_interactively): Check arg count for overflow,
9891 to avoid potential buffer overrun. Use signed char, not 'int',
9892 for 'varies' array, so that we needn't bother to check its size
9893 calculation for overflow.
9894 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
9895 * eval.c (apply_lambda):
9896 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
9897 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
9898 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
9900 * callint.c (Fcall_interactively): Don't use index var as event count.
9902 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
9903 * mem-limits.h (SIZE): Remove; no longer used.
9905 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
9907 Remove unnecessary casts.
9908 * xterm.c (x_term_init):
9909 * xfns.c (x_set_border_pixel):
9910 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
9911 These aren't needed now that we assume ANSI C.
9913 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
9914 It's more likely to cause problems (due to unsigned overflow)
9917 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
9919 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
9921 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
9923 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
9925 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
9927 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
9929 GLYPH_CODE_FACE returns EMACS_INT, not int.
9930 * dispextern.h (merge_faces):
9931 * xfaces.c (merge_faces):
9932 * xdisp.c (get_next_display_element, next_element_from_display_vector):
9933 Don't assume EMACS_INT fits in int.
9935 * character.h (CHAR_VALID_P): Remove unused parameter.
9936 * fontset.c, lisp.h, xdisp.c: All uses changed.
9938 * editfns.c (Ftranslate_region_internal): Omit redundant test.
9940 * fns.c (concat): Minor tuning based on overflow analysis.
9941 This doesn't fix any bugs. Use int to hold character, instead
9942 of constantly refetching from Emacs object. Use XFASTINT, not
9943 XINT, for value known to be a character. Don't bother comparing
9944 a single byte to 0400, as it's always less.
9946 * floatfns.c (Fexpt):
9947 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
9949 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
9952 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
9954 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
9955 Without this fix, on a 64-bit host (aset S 0 4294967386) would
9956 incorrectly succeed when S was a string, because 4294967386 was
9957 truncated before it was used.
9959 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
9960 Otherwise, an out-of-range integer could cause undefined behavior
9963 * composite.c: Use int, not EMACS_INT, for characters.
9964 (fill_gstring_body, composition_compute_stop_pos): Use int, not
9965 EMACS_INT, for values that are known to be in character range.
9966 This doesn't fix any bugs but is the usual style inside Emacs and
9967 may generate better code on 32-bit machines.
9969 Make sure a 64-bit char is never passed to ENCODE_CHAR.
9970 This is for reasons similar to the recent CHAR_STRING fix.
9971 * charset.c (Fencode_char): Check that character arg is actually
9972 a character. Pass an int to ENCODE_CHAR.
9973 * charset.h (ENCODE_CHAR): Verify that the character argument is no
9974 wider than 'int', as a compile-time check to prevent future regressions
9977 * character.c (char_string): Remove unnecessary casts.
9979 Make sure a 64-bit char is never passed to CHAR_STRING.
9980 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
9981 by silently ignoring the top 32 bits, allowing some values
9982 that were far too large to be valid characters.
9983 * character.h: Include <verify.h>.
9984 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
9985 arguments are no wider than unsigned, as a compile-time check
9986 to prevent future regressions in this area.
9988 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
9989 (Fsubst_char_in_region):
9991 * xdisp.c (decode_mode_spec_coding):
9992 Adjust to CHAR_STRING's new requirement.
9993 * editfns.c (Finsert_char, Fsubst_char_in_region):
9994 * fns.c (concat): Check that character args are actually
9995 characters. Without this test, these functions did the wrong
9996 thing with wildly out-of-range values on 64-bit hosts.
9998 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
9999 These casts should not be needed on 32-bit hosts, either.
10000 * keyboard.c (read_char):
10001 * lread.c (Fload): Remove casts to unsigned.
10003 * lisp.h (UNSIGNED_CMP): New macro.
10004 This fixes comparison bugs on 64-bit hosts.
10005 (ASCII_CHAR_P): Use it.
10006 * casefiddle.c (casify_object):
10007 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
10008 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
10009 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
10010 * dispextern.h (FACE_FROM_ID):
10011 * keyboard.c (read_char): Use UNSIGNED_CMP.
10013 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
10014 not to EMACS_INT, to avoid GCC warning.
10016 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
10018 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
10019 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
10020 isn't needed on 32-bit machines.
10022 * buffer.c (Fgenerate_new_buffer_name):
10023 Use EMACS_INT for count, not int.
10024 (advance_to_char_boundary): Return EMACS_INT, not int.
10026 * data.c (Qcompiled_function): Now static.
10028 * window.c (window_body_lines): Now static.
10030 * image.c (gif_load): Rename local to avoid shadowing.
10032 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
10033 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
10034 * alloc.c (make_save_value): Integer argument is now of type
10035 ptrdiff_t, not int.
10036 (mark_object): Use ptrdiff_t, not int.
10037 * lisp.h (pD): New macro.
10038 * print.c (print_object): Use it.
10040 * alloc.c: Use EMACS_INT, not int, to count objects.
10041 (total_conses, total_markers, total_symbols, total_vector_size)
10042 (total_free_conses, total_free_markers, total_free_symbols)
10043 (total_free_floats, total_floats, total_free_intervals)
10044 (total_intervals, total_strings, total_free_strings):
10045 Now EMACS_INT, not int. All uses changed.
10046 (Fgarbage_collect): Compute overall total using a double, so that
10047 integer overflow is less likely to be a problem. Check for overflow
10048 when converting back to an integer.
10049 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
10050 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
10051 These were 'int' variables that could overflow on 64-bit hosts;
10052 they were never used, so remove them instead of repairing them.
10053 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
10054 (inhibit_garbage_collection): Set gc_cons_threshold to max value.

10069 The definition here is exact; the one in lisp.h was approximate.
10070 (allocate_string_data): Check for string overflow. This catches
10071 some instances we weren't catching before. Also, it catches
10072 size_t overflow on (unusual) hosts where SIZE_MAX <= min
10073 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
10074 and ptrdiff_t and EMACS_INT are both 64 bits.
10076 * character.c, coding.c, doprnt.c, editfns.c, eval.c:

10582 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
10583 Do not assume that spare memory exists; that assumption is valid
10584 only if SYSTEM_MALLOC.
10585 (LARGE_REQUEST): New macro, so that the issue of large requests
10586 is separated from the issue of spare memory.

10655 instead of using explicit *_CHAR codes.
10656 (bidi_resolve_explicit, bidi_resolve_weak):

10665 (bidi_level_of_next_char): Don't try to lookup the cache for the
10666 next/previous character if nothing is cached there yet, or if we
10667 were just reseat()'ed to a new position.
10669 * xdisp.c (set_cursor_from_row): Set start and stop points
10670 according to the row's direction when priming the loop that looks
10671 for the glyph on which to display cursor.
10672 (single_display_spec_intangible_p): Function deleted.
10673 (display_prop_intangible_p): Reimplement to call
10674 handle_display_spec instead of single_display_spec_intangible_p.
10675 Accept 3 additional arguments needed by handle_display_spec.
10676 This fixes incorrect cursor motion across display property with complex
10677 values: lists, `(when COND...)' forms, etc.

10679 lists with the argument STRING its top-level element.
10680 (display_prop_string_p): Fix the condition for processing a

10683 last portion of handle_display_prop.
10684 (compute_display_string_pos): Accept additional argument
10685 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
10686 value of a `display' property is a "replacing spec".
10687 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
10688 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
10689 the display property, but just return a value indicating whether
10690 the display property will replace the characters it covers.
10691 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
10692 frame_window_p members of struct bidi_it.
10693 (compute_display_string_pos, compute_display_string_end):

10699 * keyboard.c (adjust_point_for_property): Adjust the call to
10700 display_prop_intangible_p to its new signature.

10716 All callers changed. (Bug#8762)
10718 * gnutls.c: Use Emacs's memory allocators.
10719 Without this change, the gnutls library would invoke malloc etc.
10720 directly, which causes problems on non-SYNC_INPUT hosts, and which
10721 runs afoul of improving memory_full behavior. (Bug#8761)
10722 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
10723 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
10724 xfree instead of the default malloc, realloc, free.
10725 (Fgnutls_boot): No need to check for memory allocation failure,
10726 since xmalloc does that for us.
10728 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)

10748 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
10749 for hashes and hash indexes, instead of 'unsigned' and 'int'.
10750 * alloc.c (allocate_vectorlike):
10751 Check for overflow in vector size calculations.
10752 * ccl.c (ccl_driver):
10753 Check for overflow when converting EMACS_INT to int.
10754 * fns.c, image.c: Remove unnecessary static decls that would otherwise
10755 need to be updated by these changes.
10756 * fns.c (make_hash_table, maybe_resize_hash_table):
10757 Check for integer overflow with large hash tables.
10758 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
10759 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
10760 (SXHASH_REDUCE): New macro.
10761 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
10762 Use it instead of discarding useful hash info with large hash values.
10763 (sxhash_float): New function.
10764 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
10765 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
10766 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
10767 Rewrite to use FIXNUM_BITS, as this simplifies things.
10768 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
10769 Adjust signatures to match updated version of code.
10770 (consing_since_gc): Now EMACS_INT, since a single hash table can
10771 use more than INT_MAX bytes.

10820 Make it possible to run ./temacs.
10822 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
10823 syms_of_callproc does the same thing. Remove test for

10884 * fns.c (to_uchar): Define.
10885 (crypto_hash_function): Use it to convert some newly-signed
10886 variables to unsigned, to avoid sign-extension bugs. For example,
10887 without this change, (md5 "truc") would evaluate to
10888 45723a2aff78ff4fff7fff1114760e62 rather than the expected
10889 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in

10902 that was so large that it became a float. (Bug#8722)
10904 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
10905 (Fdbus_call_method, Fdbus_call_method_asynchronously):
10906 Use XFASTINT rather than XUINT when numbers are nonnegative.
10907 (xd_append_arg, Fdbus_method_return_internal):
10908 (Fdbus_method_error_internal): Likewise. Also, for unsigned
10909 arguments, check that Lisp number is nonnegative, rather than
10910 silently wrapping negative numbers around. (Bug#8722)
10911 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
10914 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
10916 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
10918 ccl: Add integer overflow checks.
10919 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
10920 (IN_INT_RANGE): New macros.
10921 (ccl_driver): Use them to check for integer overflow when
10922 decoding a CCL program. Many of the new checks are whether XINT (x)
10923 fits in int; it doesn't always, on 64-bit hosts. The new version
10924 doesn't catch all possible integer overflows, but it's an
10925 improvement. (Bug#8719)
10927 * alloc.c (make_event_array): Use XINT, not XUINT.
10928 There's no need for unsigned here.
10930 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
10931 This follows up to the 2011-05-06 change that substituted uintptr_t
10932 for EMACS_INT. This case wasn't caught back then.
10934 Rework Fformat to avoid integer overflow issues.
10935 * editfns.c: Include <float.h> unconditionally, as it's everywhere
10936 now (part of C89). Include <verify.h>.
10937 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
10938 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
10939 (Fformat): Avoid the prepass trying to compute sizes; it was only
10940 approximate and thus did not catch overflow reliably. Instead, walk
10941 through the format just once, formatting and computing sizes as we go,
10942 checking for integer overflow at every step, and allocating a larger
10943 buffer as needed. Keep track separately whether the format is
10944 multibyte. Keep only the most-recently calculated precision, rather
10945 than them all. Record whether each argument has been converted to
10946 string. Use EMACS_INT, not int, for byte and char and arg counts.
10947 Support field widths and precisions larger than INT_MAX. Avoid
10948 sprintf's undefined behavior with conversion specifications such as %#d
10949 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
10950 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
10951 formatting out-of-range floating point numbers with int
10952 formats. (Bug#8668)
10954 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
10956 * data.c: Avoid integer truncation in expressions involving floats.
10957 * data.c: Include <intprops.h>.
10958 (arith_driver): When there's an integer overflow in an expression
10959 involving floating point, convert the integers to floating point
10960 so that the resulting value does not suffer from catastrophic
10961 integer truncation. For example, on a 64-bit host (* 4
10962 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
10963 Do not rely on undefined behavior after integer overflow.
10965 merge count_size_as_multibyte, parse_str_to_multibyte
10966 * character.c, character.h (count_size_as_multibyte):
10967 Rename from parse_str_to_multibyte; all uses changed.
10968 Check for integer overflow.
10969 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
10970 since it's now a duplicate of the other. This is more of
10971 a character than a buffer op, so better that it's in character.c.
10972 * fns.c, print.c: Adjust to above changes.
10974 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
10976 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
10978 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
10980 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
10981 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
10982 (x_clipboard_manager_save): Now static.
10983 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
10985 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
10986 (crypto_hash_function): Now static.
10987 Fix pointer signedness problems. Avoid unnecessary initializations.
10989 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
10991 * termhooks.h (Vselection_alist): Make it terminal-local.
10993 * terminal.c (create_terminal): Initialize it.
10995 * xselect.c: Support for clipboard managers.
10996 (Vselection_alist): Move to termhooks.h as terminal-local var.
10997 (LOCAL_SELECTION): New macro.
10998 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
10999 (symbol_to_x_atom): Remove gratuitous arg.
11000 (x_handle_selection_request, lisp_data_to_selection_data)
11001 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
11002 (x_own_selection, x_get_local_selection, x_convert_selection):
11003 New arg, specifying work frame. Use terminal-local Vselection_alist.
11004 (some_frame_on_display): Delete unused function.
11005 (Fx_own_selection_internal, Fx_get_selection_internal)
11006 (Fx_disown_selection_internal, Fx_selection_owner_p)
11007 (Fx_selection_exists_p): New optional frame arg.
11008 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
11009 (x_handle_selection_clear): Don't treat other terminals with the
11010 same keyboard specially. Use the terminal-local Vselection_alist.
11011 (x_clear_frame_selections): Use Frun_hook_with_args.
11013 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
11015 * xterm.h: Add support for those atoms.
11017 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
11019 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
11020 (converted_selections, conversion_fail_tag): New global variables.
11021 (x_selection_request_lisp_error): Free the above.
11022 (x_get_local_selection): Remove unnecessary code.
11023 (x_reply_selection_request): Args changed; handle arbitrary array
11024 of converted selections stored in converted_selections.
11025 Separate the XChangeProperty and SelectionNotify steps.
11026 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
11027 (x_convert_selection): New function.
11028 (x_handle_selection_event): Simplify.
11029 (x_get_foreign_selection): Don't ignore incoming requests while
11030 waiting for an answer; this will fail when we implement
11031 SAVE_TARGETS, and seems unnecessary anyway.
11032 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
11033 (Vx_sent_selection_functions): Doc fix.
11035 2011-05-26 Leo Liu <sdl.web@gmail.com>
11037 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
11039 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11041 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
11043 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
11044 for fringe update if it has periodic bitmap.
11045 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
11046 and fringe_bitmap_periodic_p.
11048 * fringe.c (get_fringe_bitmap_data): New function.
11049 (draw_fringe_bitmap_1, update_window_fringes): Use it.
11050 (update_window_fringes): Record periodicity of fringe bitmap in glyph
11051 row. Mark glyph row for fringe update if periodicity changed.
11053 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
11054 for fringe update unless it has periodic bitmap.
11056 2011-05-25 Kenichi Handa <handa@m17n.org>
11058 * xdisp.c (get_next_display_element): Set correct it->face_id for
11059 a static composition.
11061 2011-05-24 Leo Liu <sdl.web@gmail.com>
11064 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
11066 * fns.c (crypto_hash_function, Fsha1): New function.
11067 (Fmd5): Use crypto_hash_function.
11068 (syms_of_fns): Add Ssha1.
11070 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
11072 * gnutls.c: Remove unused macros.
11073 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
11074 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
11075 Remove macros that are defined and never used.
11076 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
11078 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
11080 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
11081 (Fx_get_selection_internal): Minor cleanup.
11082 (Fx_own_selection_internal): Rename arguments for consistency with
11085 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
11087 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
11089 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
11091 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
11093 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11095 * dispnew.c (scrolling_window): Don't exclude the case that the
11096 last enabled row in the desired matrix touches the bottom boundary.
11098 2011-05-21 Glenn Morris <rgm@gnu.org>
11100 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
11101 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
11102 and add some more files.
11104 2011-05-20 Eli Zaretskii <eliz@gnu.org>
11106 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
11107 report_file_error introduced by the change from 2011-05-07.
11109 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
11111 * systime.h (Time): Define only if emacs is defined.
11112 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
11113 where the include path doesn't have X11/X.h by default. See
11114 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
11116 2011-05-20 Kenichi Handa <handa@m17n.org>
11118 * composite.c (find_automatic_composition): Fix previous change.
11120 2011-05-20 Glenn Morris <rgm@gnu.org>
11122 * lisp.mk: New file, split from Makefile.in.
11123 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
11124 (shortlisp): Remove.
11125 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
11127 2011-05-19 Glenn Morris <rgm@gnu.org>
11129 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
11130 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
11131 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
11132 (lisp): Set the order to that of loadup.el.
11133 (shortlisp): Make it a copy of $lisp.
11134 (SOME_MACHINE_LISP): Remove.
11135 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
11136 Use just $shortlisp, not $SOME_MACHINE_LISP too.
11138 2011-05-18 Kenichi Handa <handa@m17n.org>
11140 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
11141 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
11142 (find_automatic_composition): Mostly rewrite for efficiency.
11144 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
11146 * makefile.w32-in: Update dependencies.
11148 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
11150 * menu.c: Include limits.h (fixes the MS-Windows build broken by
11151 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
11153 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
11155 Fix some integer overflow issues, such as string length overflow.
11157 * insdel.c (count_size_as_multibyte): Check for string overflow.
11159 * character.c (lisp_string_width): Check for string overflow.
11160 Use EMACS_INT, not int, for string indexes and lengths; in
11161 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
11162 the resulting string length overflows an EMACS_INT; instead,
11163 report a string overflow if no precision given. When checking for
11164 precision exhaustion, use a check that cannot possibly have
11165 integer overflow. (Bug#8675)
11166 * character.h (lisp_string_width): Adjust to new signature.
11168 * alloc.c (string_overflow): New function.
11169 (Fmake_string): Use it. This doesn't change behavior, but saves
11170 a few bytes and will simplify future changes.
11171 * character.c (string_escape_byte8): Likewise.
11172 * lisp.h (string_overflow): New decl.
11174 Fixups, following up to the user-interface timestamp change.
11175 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
11176 for UI timestamps, instead of unsigned long.
11177 * msdos.c (mouse_get_pos): Likewise.
11178 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
11179 * w32gui.h (Time): Define by including "systime.h" rather than by
11180 declaring it ourselves. (Bug#8664)
11182 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
11183 * image.c (clear_image_cache): Likewise.
11185 * term.c (term_mouse_position): Don't assume time_t wraparound.
11187 Be more systematic about user-interface timestamps.
11188 Before, the code sometimes used 'Time', sometimes 'unsigned long',
11189 and sometimes 'EMACS_UINT', to represent these timestamps.
11190 This change causes it to use 'Time' uniformly, as that's what X uses.
11191 This makes the code easier to follow, and makes it easier to catch
11192 integer overflow bugs such as Bug#8664.
11193 * frame.c (Fmouse_position, Fmouse_pixel_position):
11194 Use Time, not unsigned long, for user-interface timestamps.
11195 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
11196 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
11197 * keyboard.h (last_event_timestamp): Likewise.
11198 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
11199 * menu.h (xmenu_show): Likewise.
11200 * term.c (term_mouse_position): Likewise.
11201 * termhooks.h (struct input_event.timestamp): Likewise.
11202 (struct terminal.mouse_position_hook): Likewise.
11203 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
11204 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
11205 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
11206 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
11207 what it was before.
11208 * menu.h, termhooks.h: Include "systime.h", for Time.
11210 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
11211 Don't assume that the difference between two unsigned long values
11212 can fit into an integer. At this point, we know button_down_time
11213 <= event->timestamp, so the difference must be nonnegative, so
11214 there's no need to cast the result if double-click-time is
11215 nonnegative, as it should be; check that it's nonnegative, just in
11216 case. This bug is triggered when events are more than 2**31 ms
11217 apart (about 25 days). (Bug#8664)
11219 * xselect.c (last_event_timestamp): Remove duplicate decl.
11220 (x_own_selection): Remove needless cast to unsigned long.
11222 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
11223 that always fit in int. Use a sentinel instead of a counter, to
11224 avoid a temp and to allay GCC's concerns about possible int overflow.
11225 * frame.h (struct frame): Use int for menu_bar_items_used
11226 instead of EMACS_INT, since it always fits in int.
11228 * menu.c (grow_menu_items): Check for int overflow.
11230 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
11232 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
11233 Before, the code was not consistent. These values cannot exceed
11234 2**31 - 1 so there's no need to make them unsigned.
11235 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
11236 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
11237 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
11239 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
11241 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
11242 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
11243 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
11244 presumably because the widths might not match.
11246 * window.c (size_window): Avoid needless test at loop start.
11248 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
11250 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
11252 2011-05-12 Drew Adams <drew.adams@oracle.com>
11254 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
11256 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11258 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
11259 `width' to `bar_area_x' and `bar_area_width', respectively.
11260 (x_scroll_run): Take account of fringe background extension.
11262 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
11263 Rename local vars `left' and `width' to `bar_area_x' and
11264 `bar_area_width', respectively.
11265 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
11266 background extension.
11268 2011-05-10 Jim Meyering <meyering@redhat.com>
11270 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
11272 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
11274 * image.c (Finit_image_library): Return t for built-in image types,
11275 like pbm and xbm. (Bug#8640)
11277 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
11279 * w32menu.c (set_frame_menubar): Fix submenu allocation.
11281 2011-05-07 Eli Zaretskii <eliz@gnu.org>
11283 * w32console.c (Fset_screen_color): Doc fix.
11284 (Fget_screen_color): New function.
11285 (syms_of_ntterm): Defsubr it.
11287 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
11288 unlink the temporary file if Fcall_process didn't create it in the
11290 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
11291 child process will be redirected to a file specified with `:file'.
11292 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
11293 cue to call_process_cleanup not to close that handle.
11295 2011-05-07 Ben Key <bkey76@gmail.com>
11297 * makefile.w32-in: The bootstrap-temacs rule now makes use of
11298 one of two shell specific rules, either bootstrap-temacs-CMD or
11299 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
11300 to the previous implementation of the bootstrap-temacs rule.
11301 The bootstrap-temacs-CMD rule is similar to the previous
11302 implementation of the bootstrap-temacs rule except that it
11303 makes use of the ESC_CFLAGS variable instead of the CFLAGS
11306 These changes, along with some changes to nt/configure.bat,
11307 nt/gmake.defs, and nt/nmake.defs, are required to extend my
11308 earlier fix to add support for --cflags and --ldflags options
11309 that include quotes so that it works whether make uses cmd or
11312 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
11314 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
11315 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
11317 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
11318 a string. Handle both cases.
11319 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
11320 (Fdbus_register_method): Use Qinvalid_function.
11322 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
11324 * makefile.w32-in: Update dependencies.
11325 (LISP_H): Add inttypes.h and stdin.h.
11326 (PROCESS_H): Add unistd.h.
11328 2011-05-06 Eli Zaretskii <eliz@gnu.org>
11330 * lread.c: Include limits.h (fixes the MS-Windows build broken by
11331 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
11333 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
11335 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
11337 * term.c (vfatal): Remove stray call to va_end.
11338 It's not needed and the C Standard doesn't allow it here anyway.
11340 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
11341 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
11343 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
11346 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
11348 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
11350 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
11352 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
11354 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
11356 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
11357 * charset.c (Fdefine_charset_internal): Don't initialize
11358 charset.code_space[15]. The value was garbage, on hosts with
11359 32-bit int (Bug#8600).
11361 * lread.c (read_integer): Be more consistent with string-to-number.
11362 Use string_to_number to do the actual conversion; this avoids
11363 rounding errors and fixes some other screwups. Without this fix,
11364 for example, #x1fffffffffffffff was misread as -2305843009213693952.
11365 (digit_to_number): Move earlier, for benefit of read_integer.
11366 Return -1 if the digit is out of range for the base, -2 if it is
11367 not a digit in any supported base. (Bug#8602)
11369 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
11371 * dispnew.c (scrolling_window): Return 1 if we scrolled,
11372 to match comment at start of function. This also removes a
11373 GCC warning about overflow in a 32+64-bit port.
11375 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
11377 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
11378 Reported by Stefan Monnier in
11379 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
11380 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
11381 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
11383 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
11384 (EMACS_UINTPTR): Likewise, with uintptr_t.
11386 * lisp.h: Prefer 64-bit EMACS_INT if available.
11387 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
11388 on 32-bit hosts that have 64-bit int, so that they can access
11390 However, temporarily disable this change unless the temporary
11391 symbol WIDE_EMACS_INT is defined.
11393 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
11395 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
11396 This removes an assumption that EMACS_INT and long are the same
11397 width as pointers. The assumption is true for Emacs porting targets
11398 now, but we want to make other targets possible.
11399 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
11400 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
11401 In the rest of the code, change types of integers that hold casted
11402 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
11403 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
11404 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
11405 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
11406 No need to cast type when ORing.
11407 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
11408 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
11409 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
11410 assume EMACS_INT is the same width as char *.
11411 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
11412 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
11413 Remove no-longer-needed casts.
11414 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
11415 (xg_tool_bar_help_callback, xg_make_tool_item):
11416 Use EMACS_INTPTR to hold an integer
11417 that will be cast to void *; this can avoid a GCC warning
11418 if EMACS_INT is not the same width as void *.
11419 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
11420 * xdisp.c (display_echo_area_1, resize_mini_window_1):
11421 (current_message_1, set_message_1):
11422 Use a local to convert to proper width without a cast.
11423 * xmenu.c (dialog_selection_callback): Likewise.
11425 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
11426 Also, don't assume VALBITS / RAND_BITS is less than 5,
11427 and don't rely on undefined behavior when shifting a 1 left into
11429 * lisp.h (get_random): Change signature to match.
11431 * lread.c (hash_string): Use size_t, not int, for hash computation.
11432 Normally we prefer signed values; but hashing is special, because
11433 it's better to use unsigned division on hash table sizes so that
11434 the remainder is nonnegative. Also, size_t is the natural width
11435 for hashing into memory. The previous code used 'int', which doesn't
11436 retain enough info to hash well into very large tables.
11437 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
11439 * dbusbind.c: Don't possibly lose pointer info when converting.
11440 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
11441 Use XPNTR rather than XHASH, so that the high-order bits of
11442 the pointer aren't lost when converting through void *.
11444 * eval.c (Fautoload): Don't double-shift a pointer.
11446 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
11448 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
11450 * gnutls.c (DEF_GNUTLS_FN):
11451 * image.c (DEF_IMGLIB_FN): Make function pointers static.
11453 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
11455 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
11458 2011-05-05 Eli Zaretskii <eliz@gnu.org>
11460 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
11461 New version that can reserve upto 2GB of heap space.
11463 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
11465 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
11467 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
11469 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
11470 `gnutls_certificate_set_x509_key_file'.
11472 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
11474 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
11475 Update dependencies.
11477 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
11479 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
11480 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
11481 Remove unused parameter `fildes'.
11482 * process.c (read_process_output, send_process): Don't pass it.
11484 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
11486 Fix previous change: the library cache is defined in w32.c.
11487 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
11488 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
11490 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
11492 Implement dynamic loading of GnuTLS on Windows.
11494 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
11495 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
11496 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
11499 * gnutls.c (Qgnutls_dll): Define.
11500 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
11501 (gnutls_*): Declare function pointers.
11502 (init_gnutls_functions): New function to initialize function pointers.

11505 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
11506 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
11507 (emacs_gnutls_write, emacs_gnutls_read)
11508 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
11509 (Fgnutls_available_p): New function.
11510 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
11511 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.

11514 * image.c: Include w32.h.
11515 (Vimage_type_cache): Delete.
11516 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
11517 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
11518 (w32_delayed_load): Move to w32.c.
11520 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
11522 * w32.c (QCloaded_from, Vlibrary_cache): Define.
11523 (w32_delayed_load): Move from image.c. When loading a library, record
11524 its filename in the :loaded-from property of the library id.
11525 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
11526 Initialize and staticpro them.
11527 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
11529 * process.c: Include lisp.h before w32.h, not after.
11530 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
11531 instead of gnutls_record_check_pending.
11533 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
11535 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
11537 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
11538 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
11541 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
11543 * xterm.c (x_set_frame_alpha): Do not set property on anything
11544 else than FRAME_X_OUTER_WINDOW (Bug#8608).
11546 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
11548 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
11550 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
11552 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
11553 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

11562 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
11564 * callproc.c: Indentation fixup.
11566 * sysdep.c (wait_for_termination_1): Make static.
11567 (wait_for_termination, interruptible_wait_for_termination):
11568 Move after wait_for_termination_1.
11570 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
11572 * sysdep.c (interruptible_wait_for_termination): New function
11573 which is like wait_for_termination, but allows keyboard
11576 * callproc.c (Fcall_process): Add (:file "file") as an option for
11578 (Fcall_process_region): Ditto.
11580 2011-04-30 Eli Zaretskii <eliz@gnu.org>
11582 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
11583 rather than `XVECTOR (FOO)->size'.
11585 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
11586 inttypes.h, as a gnulib replacement is used if it not available in
11589 2011-04-21 Eli Zaretskii <eliz@gnu.org>
11591 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
11592 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
11593 of MOST_POSITIVE_FIXNUM. (Bug#8528)
11595 * coding.c (coding_alloc_by_realloc): Error out if destination
11596 will grow beyond MOST_POSITIVE_FIXNUM.
11597 (decode_coding_emacs_mule): Abort if there isn't enough place in
11598 charbuf for the composition carryover bytes. Reserve an extra
11599 space for up to 2 characters produced in a loop.
11600 (decode_coding_iso_2022): Abort if there isn't enough place in
11601 charbuf for the composition carryover bytes.
11603 2011-04-21 Eli Zaretskii <eliz@gnu.org>
11605 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
11606 aborting when %lld or %lll format is passed.
11607 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
11608 %llo or %llx format is passed. (Bug#8545)
11610 * window.c (window_scroll_line_based): Use a marker instead of
11611 simple variables to record original value of point. (Bug#7952)
11613 * doprnt.c (doprnt): Fix the case where a multibyte sequence
11614 produced by %s or %c overflows available buffer space. (Bug#8545)
11616 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
11618 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
11619 (SIZE_MAX): Move defn after all includes, as they might #define it.
11621 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
11623 * w32.c (init_environment): Warn about defaulting HOME to C:\.
11625 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
11627 * keyboard.c (Qdelayed_warnings_hook): Define.
11628 (command_loop_1): Run `delayed-warnings-hook'
11629 if Vdelayed_warnings_list is non-nil.
11630 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
11631 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
11633 2011-04-28 Eli Zaretskii <eliz@gnu.org>
11635 * doprnt.c (doprnt): Don't return value smaller than the buffer
11636 size if the message was truncated. (Bug#8545).
11638 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
11640 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
11641 (Fx_window_property): #if-0 the whole functions, not just the bodies.
11643 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
11645 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
11647 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
11649 * makefile.w32-in: Update dependencies.
11651 2011-04-27 Eli Zaretskii <eliz@gnu.org>
11653 Improve `doprnt' and its usage. (Bug#8545)
11654 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
11655 `format_end'. Remove support for %l as a conversion specifier.
11656 Don't use xrealloc. Improve diagnostics when the %l size modifier
11657 is used. Update the commentary.
11659 * eval.c (verror): Simplify calculation of size_t.
11661 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
11664 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
11666 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
11669 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
11671 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
11672 This makes this file independent of the recent pseudovector change.
11674 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
11676 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
11678 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
11679 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
11680 Remove unused local.
11681 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
11683 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
11684 GCC 4.6.0 optimizes based on type-based alias analysis.
11685 For example, if b is of type struct buffer * and v of type struct
11686 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
11687 != &v->size, and therefore "v->size = 1; b->size = 2; return
11688 v->size;" must therefore return 1. This assumption is incorrect
11689 for Emacs, since it type-puns struct Lisp_Vector * with many other
11690 types. To fix this problem, this patch adds a new type struct
11691 vectorlike_header that documents the constraints on layout of vectors
11692 and pseudovectors, and helps optimizing compilers not get fooled
11693 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
11694 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
11695 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
11697 (XSETPVECTYPE): Rewrite in terms of new macro.
11698 (XSETPVECTYPESIZE): New macro, specifying both type and size.
11699 This is a bit clearer, and further avoids the possibility of
11700 undesirable aliasing.
11701 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
11702 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
11703 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
11704 since Lisp_Subr is a special case (no "next" field).
11705 (ASIZE): Now uses header.size rather than size.
11706 All previous uses of XVECTOR (foo)->size replaced to use this macro,
11707 to avoid the hassle of writing XVECTOR (foo)->header.size.
11708 (struct vectorlike_header): New type.
11709 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
11710 object, to help avoid aliasing.
11711 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
11712 (SUBRP): Likewise, since Lisp_Subr is a special case.
11713 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
11714 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
11715 (struct Lisp_Hash_Table): Combine first two members into a single
11716 struct vectorlike_header member. All uses of "size" and "next" members
11717 changed to be "header.size" and "header.next".
11718 * buffer.h (struct buffer): Likewise.
11719 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
11720 * frame.h (struct frame): Likewise.
11721 * process.h (struct Lisp_Process): Likewise.
11722 * termhooks.h (struct terminal): Likewise.
11723 * window.c (struct save_window_data, struct saved_window): Likewise.
11724 * window.h (struct window): Likewise.
11725 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
11726 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
11727 * buffer.c (init_buffer_once): Likewise.
11728 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
11730 * process.c (Fformat_network_address): Use local var for size,
11733 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
11735 Make the Lisp reader and string-to-float more consistent (Bug#8525)
11736 * data.c (atof): Remove decl; no longer used or needed.
11737 (digit_to_number): Move to lread.c.
11738 (Fstring_to_number): Use new string_to_number function, to be
11739 consistent with how the Lisp reader treats infinities and NaNs.
11740 Do not assume that floating-point numbers represent EMACS_INT
11741 without losing information; this is not true on most 64-bit hosts.
11742 Avoid double-rounding errors, by insisting on integers when
11743 parsing non-base-10 numbers, as the documentation specifies.
11744 * lisp.h (string_to_number): New decl, replacing ...
11745 (isfloat_string): Remove.
11746 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
11747 (read1): Do not accept +. and -. as integers; this
11748 appears to have been a coding error. Similarly, do not accept
11749 strings like +-1e0 as floating point numbers. Do not report
11750 overflow for integer overflows unless the base is not 10 which
11751 means we have no simple and reliable way to continue.
11752 Break out the floating-point parsing into a new
11753 function string_to_number, so that Fstring_to_number parses
11754 floating point numbers consistently with the Lisp reader.
11755 (digit_to_number): Move here from data.c. Make it static inline.
11756 (E_CHAR, EXP_INT): Remove, replacing with ...
11757 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
11758 (string_to_number): New function, replacing isfloat_string.
11759 This function checks for valid syntax and produces the resulting
11760 Lisp float number too. Rework it so that string-to-number
11761 no longer mishandles examples like "1.0e+". Use strtoumax,
11762 so that overflow for non-base-10 numbers is reported only when
11763 there's no portable and simple way to convert to floating point.
11765 * textprop.c (set_text_properties_1): Rewrite for clarity,
11766 and to avoid GCC warning about integer overflow.
11768 * intervals.h (struct interval): Use EMACS_INT for members
11769 where EMACS_UINT might cause problems. See
11770 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
11771 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.

11774 (offset_intervals): Tell GCC not to worry about length overflow
11775 when negating a negative length.
11777 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
11778 (overrun_check_free): Likewise.
11780 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
11781 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
11784 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
11785 (gnutls_make_error): Rename local to avoid shadowing.

11790 * lread.c (openp): Don't stuff size_t into an 'int'.
11791 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
11792 about possible signed overflow.
11794 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
11795 (GDK_KEY_g): Don't define if already defined.
11796 (xg_prepare_tooltip): Avoid pointer signedness problem.
11797 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
11799 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
11800 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
11802 * xfns.c (Fx_window_property): Simplify a bit,
11803 to make a bit faster and to avoid GCC 4.6.0 warning.
11804 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
11806 * fns.c (internal_equal): Don't assume size_t fits in int.
11808 * alloc.c (compact_small_strings): Tighten assertion a little.
11810 Replace pEd with more-general pI, and fix some printf arg casts.
11811 * lisp.h (pI): New macro, generalizing old pEd macro to other
11812 conversion specifiers. For example, use "...%"pI"d..." rather
11813 than "...%"pEd"...".
11814 (pEd): Remove. All uses replaced with similar uses of pI.
11815 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
11816 * alloc.c (check_pure_size): Don't overflow by converting size to int.

11820 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
11821 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
11823 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
11824 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
11825 * print.c (safe_debug_print, print_object): Likewise.
11826 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
11828 Use pI instead of if-then-else-abort. Use %p to avoid casts,
11829 avoiding the 0 flag, which is not portable.

11831 * region-cache.c (pp_cache): Likewise.
11832 * xdisp.c (decode_mode_spec): Likewise.

11834 behavior on 64-bit hosts with printf arg.
11835 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
11836 (x_stop_queuing_selection_requests): Likewise.
11837 (x_get_window_property): Don't truncate byte count to an 'int'
11840 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
11841 here, since it parses constructs like leading '-' and spaces,
11842 which are not wanted; and it overflows with large numbers.
11843 Instead, simply match F[0-9]+, which is what is wanted anyway.
11845 * alloc.c: Remove unportable assumptions about struct layout.
11846 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
11847 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
11848 (allocate_vectorlike, make_pure_vector): Use the new macros,
11849 plus offsetof, to remove unportable assumptions about struct layout.
11850 These assumptions hold on all porting targets that I know of, but
11851 they are not guaranteed, they're easy to remove, and removing them
11852 makes further changes easier.
11854 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
11855 This doesn't fix a bug but makes the code clearer.
11856 (string_overrun_cookie): Now const. Use initializers that
11857 don't formally overflow signed char, to avoid warnings.
11858 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
11859 can cause Emacs to crash when string overrun checking is enabled.
11860 (allocate_buffer): Don't assume sizeof (struct buffer) is a
11861 multiple of sizeof (EMACS_INT); it need not be, if
11862 alignof(EMACS_INT) < sizeof (EMACS_INT).
11863 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
11865 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

11892 2011-04-25 Eli Zaretskii <eliz@gnu.org>
11894 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
11895 "cast to pointer from integer of different size".
11897 Improve doprnt and its use in verror. (Bug#8545)
11898 * doprnt.c (doprnt): Document the set of format control sequences
11899 supported by the function. Use SAFE_ALLOCA instead of always
11902 * eval.c (verror): Don't limit the buffer size at size_max-1, that
11903 is one byte too soon. Don't use xrealloc; instead xfree and
11906 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
11908 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the

11912 gnutls_global_initialized. Added internals for the
11913 :verify-hostname-error, :verify-error, and :verify-flags
11914 parameters of `gnutls-boot' and documented those parameters in the
11915 docstring. Start callback support.
11916 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
11917 unless a fatal error occurred. Call gnutls_alert_send_appropriate

12021 codepoint of an invalid character, to avoid displaying a bogus
12024 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to

12031 to `error' in error message about FINAL_CHAR argument. Make sure
12032 FINAL_CHAR is a character, and use %c when it is passed as
12033 argument to `error'.
12035 2011-04-23 Eli Zaretskii <eliz@gnu.org>
12037 * s/ms-w32.h (localtime): Redirect to sys_localtime.
12039 * w32.c: Include <time.h>.

12103 * dispextern.h (struct redisplay_interface): Rename param
12104 to avoid shadowing.
12105 * termhooks.h (struct terminal): Likewise.

12207 (group_in_compile_stack, re_search, re_search_2, regex_compile)
12208 (re_compile_pattern, re_exec): Declare arguments and local
12209 variables `size_t' and `ssize_t' and return values `regoff_t', as

12222 * nsfont.m: Fixed bugs in ns_get_family and
12223 ns_descriptor_to_entity that were caused by using free to
12224 deallocate memory blocks that were allocated by xmalloc (via
12225 xstrdup). This caused Emacs to crash when compiled with
12226 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
12227 --enable-checking=xmallocoverrun). xfree is now used to
12228 deallocate these memory blocks.

12655 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
12656 Mark functions with DEFUE instead of DEFUN,
12657 if they are used in other modules.
12658 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
12659 decls for now-static functions.
12660 * buffer.h (Fdelete_overlay): Remove decl.
12661 * callproc.c (Fgetenv_internal): Mark as internal.
12662 * composite.c (Fremove_list_of_text_properties): Remove decl.

12668 (Funintern): Remove extern decl; now in .h file where it belongs.
12669 * fileio.c (Fmake_symbolic_link): New forward static decl.
12670 * image.c (Finit_image_library): New forward static decl.
12671 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
12672 * intervals.h (Fprevious_property_change):

12696 2011-04-13 Eli Zaretskii <eliz@gnu.org>
12698 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
12699 when at ZV. (Bug#8487)
12701 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
12703 * charset.c (Fclear_charset_maps): Use xfree instead of free.
12705 * keyboard.c (parse_tool_bar_item): Likewise.
12706 * sound.c (sound_cleanup, alsa_close): Likewise.
12707 * termcap.c (tgetent): Likewise.
12708 * xfns.c (x_default_font_parameter): Likewise.
12709 * xsettings.c (read_and_apply_settings): Likewise.
12711 * alloc.c (overrun_check_malloc, overrun_check_realloc)
12712 (overrun_check_free): Protoize.
12714 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
12716 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
12717 since callers should never pass a negative size.
12718 Change the signature to match that of plain 'read' and 'write'; see
12719 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
12720 * lisp.h: Update prototypes of emacs_write and emacs_read.
12722 2011-04-11 Eli Zaretskii <eliz@gnu.org>
12724 * xdisp.c (redisplay_window): Don't try to determine the character
12725 position of the scroll margin if the window start point w->startp
12726 is outside the buffer's accessible region. (Bug#8468)
12728 2011-04-10 Eli Zaretskii <eliz@gnu.org>
12730 Fix write-region and its subroutines for buffers > 2GB.
12731 * fileio.c (a_write, e_write): Modify declaration of arguments and
12732 local variables to support buffers larger than 2GB.
12733 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
12735 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
12736 argument, local variables, and return value.
12738 * lisp.h: Update prototypes of emacs_write and emacs_read.
12740 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
12742 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
12744 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
12746 Fix more problems found by GCC 4.6.0's static checks.
12748 * xdisp.c (vmessage): Use a better test for character truncation.
12750 * charset.c (load_charset_map): <, not <=, for optimization,
12751 and to avoid potential problems with integer overflow.
12752 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
12753 * casetab.c (set_identity, shuffle): Likewise.
12754 * editfns.c (Fformat): Likewise.
12755 * syntax.c (skip_chars): Likewise.
12757 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
12758 This also lets GCC 4.6.0 generate slightly better loop code.
12760 * callint.c (Fcall_interactively): <, not <=, for optimization.
12761 (Fcall_interactively): Count the number of arguments produced,
12762 not the number of arguments given. This is simpler and lets GCC
12763 4.6.0 generate slightly better code.
12765 * ftfont.c: Distingish more carefully between FcChar8 and char.
12766 The previous code passed unsigned char * to a functions like
12767 strlen and xstrcasecmp that expect char *, which does not
12768 conform to the C standard.
12769 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
12770 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
12771 char * when the C standard requires it.
12773 * keyboard.c (read_char): Remove unused var.
12775 * eval.c: Port to Windows vsnprintf (Bug#8435).
12776 Include <limits.h>.
12777 (SIZE_MAX): Define if the headers do not.
12778 (verror): Do not give up if vsnprintf returns a negative count.
12779 Instead, grow the buffer. This ports to Windows vsnprintf, which
12780 does not conform to C99. Problem reported by Eli Zaretskii.
12781 Also, simplify the allocation scheme, by avoiding the need for
12782 calling realloc, and removing the ALLOCATED variable.
12784 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
12786 Remove invocations of doprnt, as Emacs now uses vsnprintf.
12787 But keep the doprint source code for now, as we might revamp it
12788 and use it again (Bug#8435).
12789 * lisp.h (doprnt): Remove.
12790 * Makefile.in (base_obj): Remove doprnt.o.
12791 * deps.mk (doprnt.o): Remove.
12793 error: Print 32- and 64-bit integers portably (Bug#8435).
12794 Without this change, on typical 64-bit hosts error ("...%d...", N)
12795 was used to print both 32- and 64-bit integers N, which relied on
12796 undefined behavior.
12797 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
12798 * lisp.h (error, verror): Mark as printf-like functions.
12799 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
12800 Report overflow in size calculations when allocating printf buffer.
12801 Do not truncate output string at its first null byte.
12802 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
12803 Truncate the output at a character boundary, since vsnprintf does not
12805 * charset.c (check_iso_charset_parameter): Convert internal
12806 character to string before calling 'error', since %c now has the
12808 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
12809 overflow when computing char to be passed to 'error'. Do not
12810 pass Lisp_Object to 'error'; pass the integer instead.
12811 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
12812 formatted with plain %d.
12814 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
12816 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
12818 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
12820 * xterm.c (x_catch_errors): Remove duplicate declaration.
12822 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
12824 * xdisp.c, lisp.h (message_nolog): Remove; unused.
12826 2011-04-10 Jim Meyering <meyering@redhat.com>
12828 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
12829 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
12830 return ssize_t not "int", and use size_t as the buffer length.
12831 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
12832 * gnutls.h: Update declarations.
12833 * process.c (read_process_output): Use ssize_t, to match.
12834 (send_process): Likewise.
12836 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
12838 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
12840 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
12842 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
12843 Use unsigned char, to match FcChar8 type definition.
12845 * xterm.c (handle_one_xevent):
12846 * xmenu.c (create_and_show_popup_menu):
12847 * xselect.c (x_decline_selection_request)
12848 (x_reply_selection_request): Avoid type-punned deref of X events.
12850 2011-04-09 Eli Zaretskii <eliz@gnu.org>
12852 Fix some uses of `int' instead of EMACS_INT.
12853 * search.c (string_match_1, fast_string_match)
12854 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
12855 (scan_buffer, find_next_newline_no_quit)
12856 (find_before_next_newline, search_command, Freplace_match)
12857 (Fmatch_data): Make some `int' variables be EMACS_INT.
12859 * xdisp.c (display_count_lines): 3rd argument and return value now
12860 EMACS_INT. All callers changed.
12861 (pint2hrstr): Last argument is now EMACS_INT.
12863 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
12864 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
12865 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)

12868 (decode_coding_ccl, decode_coding_charset)
12869 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
12870 (decode_coding_iso_2022, decode_coding_emacs_mule)
12871 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
12872 <char_offset, last_offset>: Declare EMACS_INT.

12874 (encode_coding_emacs_mule, encode_invocation_designation)
12875 (encode_designation_at_bol, encode_coding_iso_2022)
12876 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
12877 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
12879 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
12880 (encode_invocation_designation): Last argument P_NCHARS is now
12882 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
12883 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
12885 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
12888 * ccl.c (Fccl_execute_on_string): Declare some variables
12891 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
12893 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
12895 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
12897 * process.c (Fformat_network_address): Doc fix.
12899 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
12901 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
12903 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
12905 * keyboard.c (read_char): Call Lisp function help-form-show,
12906 instead of using internal_with_output_to_temp_buffer.
12907 (Qhelp_form_show): New var.
12908 (syms_of_keyboard): Use DEFSYM macro.
12910 * print.c (internal_with_output_to_temp_buffer): Function deleted.
12912 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
12914 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
12916 * process.c (Flist_processes): Remove to Lisp.
12917 (list_processes_1): Delete.
12919 2011-04-06 Eli Zaretskii <eliz@gnu.org>
12921 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
12923 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
12925 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
12927 Fix more problems found by GCC 4.6.0's static checks.

12931 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
12933 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
12935 * xdisp.c (vmessage): Mark as a printf-like function.
12937 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
12939 * sound.c (sound_warning): Don't crash if arg contains a printf format.
12941 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
12942 printf-like functions.
12943 (tiff_load): Add casts to remove these marks before passing them
12944 to system-supplied API.
12946 * eval.c (Fsignal): Remove excess argument to 'fatal'.
12948 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
12949 This avoids several warnings with gcc -Wstrict-overflow.
12950 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
12951 directly, rather than having caller test rule sign. This avoids
12952 some unnecessary tests.
12953 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
12954 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
12955 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
12957 * xfont.c (xfont_text_extents): Remove var that was set but not used.
12958 (xfont_open): Avoid unnecessary tests.
12960 * composite.c (composition_gstring_put_cache): Use unsigned integer.
12962 * composite.h, composite.c (composition_gstring_put_cache):
12963 Use EMACS_INT, not int, for length.

12966 breaking out part of COMPOSITION_DECODE_RULE.
12967 (COMPOSITION_DECODE_RULE): Use it.

12969 by using the new macro.
12971 * textprop.c (set_text_properties_1): Change while to do-while,
12972 since the condition is always true at first.
12974 * intervals.c (graft_intervals_into_buffer): Mark var as used.
12975 (interval_deletion_adjustment): Return unsigned value.
12978 * process.c (list_processes_1, create_pty, read_process_output):

12988 (update_syntax_table): Use unsigned instead of int.
12990 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
12991 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
12992 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
12994 * print.c (print_error_message): Avoid int overflow.
12996 * font.c (font_list_entities): Redo for clarity,
12997 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
12999 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
13000 (font_score): Avoid potential overflow in diff calculation.
13002 * fns.c (substring_both): Remove var that is set but not used.
13003 (sxhash): Redo loop for clarity and to avoid wraparound warning.
13005 * eval.c (funcall_lambda): Rename local to avoid shadowing.
13007 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
13008 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
13009 can always succeed if overflow has undefined behavior.
13011 * search.c (boyer_moore, wordify): Remove vars set but not used.
13012 (wordify): Omit three unnecessary tests.
13014 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
13015 All callers changed. This avoids the need for an unused var.
13017 * casefiddle.c (casify_region): Remove var that is set but not used.
13019 * dired.c (file_name_completion): Remove var that is set but not used.
13021 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
13023 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
13024 (Finsert_file_contents): Remove unnecessary code checking fd.
13026 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
13027 Check for integer overflow on size calculations.
13029 * buffer.c (Fprevious_overlay_change): Remove var that is set
13032 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
13033 Remove vars that are set but not used.
13034 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
13035 (timer_check_2): Mark vars as initialized.
13037 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
13039 * image.c (lookup_image): Remove var that is set but not used.
13040 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
13042 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
13043 that are set but not used.
13045 * xfns.c (make_invisible_cursor): Don't return garbage
13046 if XCreateBitmapFromData fails (Bug#8410).
13048 * xselect.c (x_get_local_selection, x_handle_property_notify):
13049 Remove vars that are set but not used.
13051 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
13052 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
13054 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
13055 Remove var that is set but not used.

13057 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
13058 Check for overflow.

13061 (map_tty_color) [!defined MSDOS]: Likewise.
13063 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
13065 * coding.c: Remove vars that are set but not used.
13066 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
13067 All callers changed.
13068 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
13069 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
13070 (decode_coding_charset): Remove vars that are set but not used.
13072 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
13073 that is set but not used.
13075 * print.c (print_object): Remove var that is set but not used.
13077 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
13078 The gnulib version avoids calling malloc in the usual case,
13079 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
13080 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
13081 * filelock.c (current_lock_owner): Likewise.
13082 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
13083 * sysdep.c: Include allocator.h, careadlinkat.h.
13084 (emacs_no_realloc_allocator): New static constant.
13085 (emacs_readlink): New function.
13086 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
13087 ../lib/careadlinkat.h.
13089 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
13091 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
13092 first non-nil return value).
13094 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
13096 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
13097 if not defined (Bug#8403).
13099 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
13101 * xdisp.c (display_count_lines): Remove parameter `start',
13102 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.

13106 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
13107 and thereabouts. All callers changed.
13108 (get_per_char_metric): Remove parameter `f', unused since
13109 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
13111 2011-04-02 Jim Meyering <meyering@redhat.com>
13113 do not dereference NULL upon failed strdup
13114 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
13115 (ns_get_family): Likewise.
13117 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
13119 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
13121 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
13123 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
13126 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
13128 Add lexical binding.
13130 * window.c (Ftemp_output_buffer_show): New fun.
13131 (Fsave_window_excursion):
13132 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
13134 * lread.c (lisp_file_lexically_bound_p): New function.
13135 (Fload): Bind Qlexical_binding.
13136 (readevalloop): Remove `evalfun' arg.
13137 Bind Qinternal_interpreter_environment.
13138 (Feval_buffer): Bind Qlexical_binding.
13139 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
13141 (syms_of_lread): Declare `lexical-binding'.
13143 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
13145 * keyboard.c (eval_dyn): New fun.
13146 (menu_item_eval_property): Use it.
13148 * image.c (parse_image_spec): Use Ffunctionp.
13150 * fns.c (concat, mapcar1): Accept byte-code-functions.
13152 * eval.c (Fsetq): Handle lexical vars.
13153 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
13154 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
13155 (FletX, Flet): Obey lexical binding.
13156 (Fcommandp): Handle closures.
13157 (Feval): New `lexical' arg.
13158 (eval_sub): New function extracted from Feval. Use it almost
13159 everywhere where Feval was used. Look up vars in lexical env.
13161 (Ffunctionp): Move from subr.el.
13162 (Ffuncall): Handle closures.
13163 (apply_lambda): Remove `eval_flags'.
13164 (funcall_lambda): Handle closures and new byte-code-functions.
13165 (Fspecial_variable_p): New function.
13166 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
13167 but without exporting it to Lisp.
13169 * doc.c (Fdocumentation, store_function_docstring):
13170 * data.c (Finteractive_form): Handle closures.
13172 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
13175 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
13177 (exec_byte_code): New function extracted from Fbyte_code to handle new
13178 calling convention for byte-code-functions. Add new byte-codes.
13180 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
13182 * alloc.c (Fmake_symbol): Init new `declared_special' field.
13184 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
13186 * xdisp.c (redisplay_internal): Fix prototype.
13188 2011-03-31 Eli Zaretskii <eliz@gnu.org>
13190 * xdisp.c (SCROLL_LIMIT): New macro.
13191 (try_scrolling): Use it when setting scroll_limit.
13192 Limit scrolling to 100 screen lines.
13193 (redisplay_window): Even when falling back on "recentering",
13194 position point in the window according to scroll-conservatively,
13195 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
13197 (try_scrolling): When point is above the window, allow searching
13198 as far as scroll_max, or one screenful, to compute vertical
13199 distance from PT to the scroll margin position. This prevents
13200 try_scrolling from unnecessarily failing when
13201 scroll-conservatively is set to a value slightly larger than the
13202 window height. Clean up the case of PT below the margin at bottom
13203 of window: scroll_max can no longer be INT_MAX. When aggressive
13204 scrolling is in use, don't let point enter the opposite scroll
13205 margin as result of the scroll.
13206 (syms_of_xdisp) <scroll-conservatively>: Document the
13207 threshold of 100 lines for never-recentering scrolling.
13209 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
13211 * dispextern.h (move_it_by_lines):
13212 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
13213 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
13214 (message_log_check_duplicate): Remove parameters `prev_bol' and
13215 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
13216 (redisplay_internal): Remove parameter `preserve_echo_area',
13217 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
13219 * indent.c (Fvertical_motion):
13220 * window.c (window_scroll_pixel_based, Frecenter):
13221 Don't pass `need_y_p' to `move_it_by_lines'.
13223 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
13225 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
13226 steal a few bits to be more compact.
13227 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
13228 Remove unneeded casts.
13230 * bytecode.c (Fbyte_code): CAR and CDR can GC.
13232 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
13234 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
13235 binding" message (bug#7967).
13237 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
13239 Fix more problems found by GCC 4.6.0's static checks.
13241 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
13242 Remove unused local var.
13244 * editfns.c (Fmessage_box): Remove unused local var.
13246 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
13247 (note_mode_line_or_margin_highlight, note_mouse_highlight):
13248 Omit unused local vars.
13249 * window.c (shrink_windows): Omit unused local var.
13250 * menu.c (digest_single_submenu): Omit unused local var.
13251 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
13252 Omit unused local var.
13254 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
13255 Don't assume string length fits in int.
13256 (keyremap_step, read_key_sequence): Use size_t for sizes.
13257 (read_key_sequence): Don't check last_real_key_start redundantly.
13259 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
13260 instead of alloca (Bug#8344).
13262 * eval.c (Fbacktrace): Don't assume nargs fits in int.
13263 (Fbacktrace_frame): Don't assume nframes fits in int.
13265 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
13267 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
13270 * term.c (produce_glyphless_glyph): Remove unnecessary test.
13272 * cm.c (calccost): Turn while-do into do-while, for clarity.
13274 * keyboard.c (syms_of_keyboard): Use the same style as later
13275 in this function when indexing through an array. This also
13276 works around GCC bug 48267.
13278 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
13280 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
13282 * chartab.c (sub_char_table_ref_and_range): Redo for slight
13283 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
13285 * keyboard.c, keyboard.h (num_input_events): Now size_t.
13286 This avoids undefined behavior on integer overflow, and is a bit
13287 more convenient anyway since it is compared to a size_t variable.
13289 Variadic C functions now count arguments with size_t, not int.
13290 This avoids an unnecessary limitation on 64-bit machines, which
13291 caused (substring ...) to crash on large vectors (Bug#8344).
13292 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
13293 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

13299 (internal_condition_case_n, run_hook_with_args, apply_lambda)
13300 (funcall_lambda, mark_backtrace): Likewise.
13301 * fns.c (concat): Likewise.
13302 * frame.c (x_set_frame_parameters): Likewise.
13303 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
13304 0 if not found, not -1. All callers changed.
13306 * alloc.c (garbage_collect): Don't assume stack size fits in int.
13307 (stack_copy_size): Now size_t, not int.
13308 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
13310 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
13312 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',

13314 All callers changed.
13316 * lisp.h (multibyte_char_to_unibyte):
13317 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
13318 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

13324 * xdisp.c (message_dolog, set_message_1): All callers changed.
13326 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
13328 * keyboard.c (safe_run_hook_funcall): New function.
13329 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
13330 don't set the hook to nil, but remove the offending function instead.
13331 (Qcommand_hook_internal): Remove, unused.
13332 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
13333 Vcommand_hook_internal.
13335 * eval.c (enum run_hooks_condition): Remove.
13336 (funcall_nil, funcall_not): New functions.
13337 (run_hook_with_args): Call each function through a `funcall' argument.
13338 Remove `cond' argument, now redundant.
13339 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
13340 (Frun_hook_with_args_until_failure): Adjust accordingly.
13341 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
13343 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
13345 * dispextern.h (string_buffer_position): Remove declaration.
13347 * print.c (strout): Remove parameter `multibyte', unused since
13348 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
13350 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
13351 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
13352 All callers changed.
13354 * w32.c (_wsa_errlist): Use braces for struct initializers.

13357 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
13358 All callers changed.

13364 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
13365 All callers changed.
13367 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
13369 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

13409 * keyboard.h (timer_check, show_help_echo): Remove unused parameters.
13411 * keyboard.c (timer_check): Remove parameter `do_it_now',
13412 unused since 1996-04-12T06:01:29Z!rms@gnu.org.
13413 (show_help_echo): Remove parameter `ok_to_overwrite_keystroke_echo',
13414 unused since 2008-04-19T19:30:53Z!monnier@iro.umontreal.ca.

13417 * w32menu.c (w32_menu_display_help):
13418 * xmenu.c (show_help_event, menu_help_callback):
13419 Adjust calls to `show_help_echo'.
13421 * gtkutil.c (xg_maybe_add_timer):
13422 * keyboard.c (readable_events):
13423 * process.c (wait_reading_process_output):
13424 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.

13501 2011-03-23 Julien Danjou <julien@danjou.info>
13503 * term.c (Fsuspend_tty, Fresume_tty):

13513 * buffer.c (Fkill_all_local_variables):
13514 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
13516 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
13517 unconditionally since it does the check itself.
13519 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
13521 Fix more problems found by GCC 4.5.2's static checks.
13523 * coding.c (encode_coding_raw_text): Avoid unnecessary test
13524 the first time through the loop, since we know p0 < p1 then.
13525 This also avoids a gcc -Wstrict-overflow warning.
13527 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
13528 leading to a memory leak, possible in functions like
13529 load_charset_map_from_file that can allocate an unbounded number
13530 of objects (Bug#8318).
13532 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
13533 that could (at least in theory) be that large.
13535 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
13536 This is less likely to overflow, and avoids undefined behavior if
13537 overflow does occur. All callers changed. Use strtoul to scan
13538 for the unsigned long integer.

13555 * process.c (Fmake_network_process): Use socklen_t, not int,
13556 where POSIX says socklen_t is required in portable programs.
13557 This fixes a porting bug on hosts like 64-bit HP-UX, where
13558 socklen_t is wider than int (Bug#8277).
13559 (Fmake_network_process, server_accept_connection):
13560 (wait_reading_process_output, read_process_output):
13563 * process.c: Rename or move locals to avoid shadowing.

13575 Include tparam.h instead, since it declares them.
13576 * cm.h (PC): Remove extern decl; tparam.h now does this.

13578 * terminfo.c: Include tparam.h, to check interfaces.
13579 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
13580 (tparam): Adjust signature to match interface in tparam.h;
13581 this removes some undefined behavior. Check that outstring and len
13582 are zero, which they always are with Emacs.
13583 * tparam.h (PC, BC, UP): New extern decls.
13585 * xftfont.c (xftfont_shape): Now static, and defined only if needed.

13627 (wav_play): Initialize a variable to 0, to prevent undefined
13628 behavior (Bug#8278).

13632 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
13634 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
13635 clobbering (Bug#8298).
13636 * sysdep.c (sys_subshell): Likewise.
13637 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
13639 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
13640 This should get cleaned up, so that child_setup has the
13641 same signature on all platforms.
13643 * callproc.c (call_process_cleanup): Now static.
13644 (relocate_fd): Rename locals to avoid shadowing.
13646 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
13648 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
13649 not to be necessary, and produces flickering.

13703 to avoid gcc -Wbad-function-cast warning.
13704 Use a different way to cause a compilation error if anyone uses
13705 n rather than nn, a way that does not involve shadowing.
13706 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
13708 * deps.mk (unexalpha.o): Remove; unused.

13804 (GC_STRING_CHARS): Remove; not used.
13805 (Fmemory_limit): Cast sbrk's returned value to char *.
13807 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

13815 to use the following functions instead of these macros.
13816 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
13817 EMACS_INT, since callers assume the returned value fits in int.
13818 (upcase1): Likewise, for UPCASE_TABLE.
13819 (uppercasep, lowercasep, upcase): New static inline functions.
13820 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

13830 (regex_compile, re_match_2_internal): Mark locals as initialized.
13831 (RETALLOC_IF): Define only if needed.
13832 (WORDCHAR_P): Likewise. This one is never needed, but is used
13833 only in a comment talking about a compiler bug, so put inside
13834 the #if 0 of that comment.
13835 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
13836 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

13863 New macros, so that the caller can use some names other than
13864 gcpro1, gcpro2, etc.
13865 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
13867 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
13868 argument, for consistency with GCPRO2_VAR, etc: it is now the
13869 prefix of the variable, not the variable itself. All uses
13871 * dired.c (directory_files_internal, file_name_completion):
13872 Rename locals to avoid shadowing.
13874 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
13875 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
13876 dired.c's scmp function, had undefined behavior.
13877 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
13878 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
13879 * buffer.h: ... to here, because these macros use current_buffer,
13880 and the new implementation with inline functions needs to have
13881 current_buffer in scope now, rather than later when the macros
13883 (downcase, upcase1): New static inline functions.
13884 (DOWNCASE, UPCASE1): Reimplement using these functions.
13885 This avoids undefined behavior in expressions like
13886 DOWNCASE (x) == DOWNCASE (y), which previously suffered
13887 from race conditions in accessing the global variables
13888 case_temp1 and case_temp2.
13889 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
13890 * lisp.h (case_temp1, case_temp2): Remove their decls.
13891 * character.h (ASCII_CHAR_P): Move from here ...
13892 * lisp.h: ... to here, so that the inline functions mentioned
13893 above can use them.
13895 * dired.c (directory_files_internal_unwind): Now static.
13897 * fileio.c (file_name_as_directory, directory_file_name):

13900 (file_name_as_directory): Use const pointers when appropriate.
13901 (Fexpand_file_name): Likewise. In particular, newdir might
13902 point at constant storage, so make it a const pointer.

13904 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
13906 (Fset_file_times, Finsert_file_contents, auto_save_error):

13911 to avoid shadowing.
13913 * marker.c (bytepos_to_charpos): Remove; unused.
13915 * lisp.h (verify_bytepos, count_markers): New decls,
13916 so that gcc does not warn that these functions aren't declared.
13918 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
13919 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
13920 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
13921 (copy_text): Remove unused local var.

13926 * buffer.c (fix_overlays_before): Mark locals as initialized.
13927 (fix_start_end_in_overlays): Likewise. This function should be
13928 simplified by using pointers-to-pointers, but that's a different
13930 (switch_to_buffer_1): Now static.
13931 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
13932 (report_overlay_modification): Rename locals to avoid shadowing.

13937 to suppress a gcc -Wclobbered warning that does not seem to be right.
13938 (MAXPATHLEN): Define only if needed.
13940 * process.c (serial_open, serial_configure): Move decls from here ...
13941 * systty.h: ... to here, so that they can be checked.
13943 * fns.c (get_random, seed_random): Move extern decls from here ...

13980 if GCC considers string literals to be constants.
13982 * lisp.h (fatal_error_signal): Add decl, since it's exported.
