90 * alloc.c (listn): Fix the order the arguments are consed onto the
91 list.
93 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
94 enumeration constants, as PURE and HEAP are too general, and clash
95 with other headers and sources, such as gmalloc.c and the
96 MS-Windows system headers. All users changed.

113 Improve GDB symbol export (Bug#12036).
114 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
115 arms of an 'if', not using conditional expressions; otherwise GDB
116 complains about the types in the unevaluated arm when the argument
117 is an integer literal.
118 (xgetint): Simplify expression.
119 * alloc.c (gdb_make_enums_visible): New constant. This ports to
120 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
121 Zaretskii in <http://bugs.gnu.org/12036#13>.
122 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
123 needed now that we have gdb_make_enums_visible.
124 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)

168 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
169 emacs.c, as this is a more-suitable home. Had this been done earlier
170 the fix for 12036 would have avoided some of the problems noted in
171 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
172 would have been more obvious.
173 * emacs.c: Do not include <verify.h>; no longer needed.
174 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
175 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
176 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):

182 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
183 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
184 not be usable in #if. This simplifies things.
186 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
188 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
190 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>

193 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
194 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
195 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
196 Adjust to changes in lisp.h and emacs.c, by using
197 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
198 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
199 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
200 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
201 instead of gdb_valbits.
202 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
203 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
204 instead of gdb_array_mark_flag.
205 (xboolvector): Get size from $->size, not $->header.size.
206 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
207 (xreload, hook-run, hookpost-run): Remove.
208 * emacs.c: Include <verify.h>.
209 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
210 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
211 Remove.
212 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
213 (gdb_USE_LSB_TAG): New enum constants.
214 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
215 Also define these as enum constants, so they're visible to GDB.
216 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
217 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
218 as constants, so they're visible to GDB.
219 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)

221 Now enum constants, not macros, so they're visible to GDB.
222 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
223 more convenient now. All uses changed.
224 (VALMASK) [USE_LSB_TAG]: Also define in this case.

235 add argument, tune behavior, and adjust all callers.
237 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
239 Use typedef for EMACS_INT, EMACS_UINT.
240 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
241 than macros. This simplifies debugging in the usual case, since
242 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
243 and it allows expressions involving EMACS_INT casts.
244 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
246 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>
248 * nsterm.m (ns_read_socket): Return early if there is a modal

258 Adjust buffer text indirection counters at the end of Fkill_buffer.
259 * buffer.c (Fkill_buffer): Adjust indirection counters when the
260 buffer is definitely dead. This should really fix an issue reported
261 by Christoph Scholtes again. (Bug#12007).
262 (init_buffer_once): Initialize indirection counters of
263 buffer_defaults and buffer_local_symbols (for sanity and safety).
265 2012-07-24 Eli Zaretskii <eliz@gnu.org>
267 * xdisp.c (init_iterator): Don't compute dimensions of truncation
268 and continuation glyphs on tooltip frames, leave them at zero.
269 Avoids continued lines in tooltips. (Bug#11832)
271 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
273 Simplify copy_overlay.
274 * buffer.c (copy_overlay): Simplify. Use build_marker.

280 or invalid. (Bug#12025)
282 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
283 it signals an error when a tooltip frame is being created.
285 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>

296 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
298 Swap buffer text indirection counters in Fbuffer_swap_text.
299 * buffer.c (Fbuffer_swap_text): Swap indirections too.
300 This avoids crash reported by Christoph Scholtes at
301 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
303 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
305 * nsmenu.m (Popdown_data): New struct.
306 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
307 free Popdown_data.
308 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
309 (initWithContentRect): Make imgView and contentView non-static
310 and autorelease them. Also autorelease img and matrix (Bug#12005).
311 (dealloc): Remove (Bug#12005).

328 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
330 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
331 as it's limited by the amount of memory, not by INT_MAX.
333 2012-07-21 Eli Zaretskii <eliz@gnu.org>
335 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
336 in special-event-map. See the discussion at
337 http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00417.html
338 for the reasons.
340 * w32menu.c (add_menu_item): Cast to ULONG_PTR when assigning

395 * font.c (font_open_by_name): Change 2nd and 3rd args to the only arg
396 of type Lisp_Object to avoid redundant calls to make_unibyte_string.
397 Adjust users accordingly.
398 * font.h (font_open_by_name): Adjust prototype.
400 2012-07-20 Dmitry Antipov <dmantipov@yandex.ru>

417 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
418 'for_each_per_buffer_object_at'.
419 All uses changed. It's better to use upper-case for macros that
420 cannot be implemented as functions, to give the reader a clue
421 that they're special.
423 2012-07-19 Stefan Monnier <monnier@iro.umontreal.ca>
425 * alloc.c (Fgarbage_collect): Tweak docstring.

1006 * alloc.c (mark_memory): Guard the "no_address_safety_analysis"
1007 function attribute, so we only use it if it exists in the
1008 compiler.
1010 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
1012 Avoid call to strlen in fast_c_string_match_ignore_case.

1059 * s/aix4-2.h (unix): Remove; no longer needed.
1061 EMACS_TIME simplification (Bug#11875).
1062 This replaces macros (which typically do not work in GDB)
1063 with functions, typedefs and enums, making the code easier to debug.
1064 The functional style also makes code easier to read and maintain.
1065 * systime.h: Include <sys/time.h> on all hosts, not just if
1066 WINDOWSNT, since 'struct timeval' is needed in general.

1079 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
1080 not functions. All uses rewritten to use the following, respectively:
1081 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
1082 (add_emacs_time, sub_emacs_time): New functions.
1083 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.

1100 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
1101 (menu_separator_name_p):
1102 * nsmenu.m (ns_update_menubar):
1103 Prefer memcmp to strncmp when either will do.
1104 * nsterm.m: Include <ftoastr.h>.
1105 (ns_get_color):
1106 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
1107 Prefer snprintf to strncpy.
1108 * nsterm.m (ns_term_init):
1109 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
1110 * nsterm.m (ns_term_init):
1111 Avoid the need for strncpy, by using build_string or
1112 make_unibyte_string directly. Use dtoastr, not snprintf.
1113 * process.c (Fmake_network_process): Diagnose service names that
1114 are too long, rather than silently truncating them or creating
1115 non-null-terminated names.

1117 * sysdep.c (system_process_attributes) [GNU_LINUX]:
1118 Prefer sprintf to strncat.
1119 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
1120 Prefer vsnprintf to vsprintf + strncpy.
1122 2012-07-10 Glenn Morris <rgm@gnu.org>

1125 Clarify fallback case.
1127 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
1129 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
1130 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
1131 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
1132 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
1133 where argument type is known to be a Lisp_Cons.

1147 (build_pure_c_string): New function, defined as static inline. This
1148 provides a better opportunity to optimize away calls to strlen when
1149 the function is called with compile-time constant argument.
1150 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
1151 argument, adjust users accordingly. Use build_pure_c_string where
1152 appropriate.
1153 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
1154 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
1155 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
1157 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
1159 Avoid calls to strlen in miscellaneous functions.
1160 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
1161 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
1162 * lread.c (openp): Likewise.
1164 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
1166 Avoid calls to strlen in path processing functions.
1167 * fileio.c (file_name_as_directory): Add comment. Change to add
1168 srclen argument and return the length of result. Adjust users
1169 accordingly.
1170 (directory_file_name): Fix comment. Change to add srclen argument,

1182 * s/gnu.h (DATA_START): Move definitions to configure.
1184 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
1185 We include usg5-4-common.h, which defines them both.
1187 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
1188 O_RDONLY already includes it).
1190 Stop ns builds setting the EMACSLOADPATH environment variable.
1191 * nsterm.m (ns_load_path): Rename from ns_init_paths.
1192 Now it does not set EMACSLOADPATH, just returns the load-path string.
1193 * nsterm.h: Update accordingly.
1194 * lread.c [HAVE_NS]: Include nsterm.h.
1195 (init_lread) [HAVE_NS]: Use ns_load_path.

1198 2012-07-09 Glenn Morris <rgm@gnu.org>
1200 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
1201 since the included bsd-common.h does so.
1203 Stop ns builds setting the EMACSPATH environment variable.
1204 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
1205 (ns_init_paths): Do not set EMACSPATH.
1206 * nsterm.h (ns_exec_path): Add it.
1207 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:

1210 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
1212 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
1214 * process.c (wait_reading_process_output): 'waitchannels' was unset
1215 when read_kbd || !NILP (wait_for_cell); fix this.
1217 Add GCC-style 'const' attribute to functions that can use it.
1218 * character.h (char_resolve_modifier_mask):
1219 * keyboard.h (make_ctrl_char):
1220 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)

1231 Minor improvements to make_formatted_string.
1232 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
1233 where int is good enough, as vsprintf returns an int.
1234 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
1236 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
1238 Use make_formatted_string to avoid double length calculation.
1239 * lisp.h (make_formatted_string): New prototype.

1263 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
1265 Move marker debugging code under MARKER_DEBUG.
1266 * marker.c (MARKER_DEBUG): Move marker debugging code under
1267 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
1268 for bootstrap with --enable-checking (~3x slowdown reported
1269 by Juanma Barranquero <lekktu@gmail.com>).
1270 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
1272 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
1274 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
1275 See <http://bugs.gnu.org/11825#29>.
1277 2012-07-08 Eli Zaretskii <eliz@gnu.org>
1279 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
1280 has no font, use the frame's font. (Bug#11813)
1281 (display_line): Add commentary about displaying truncation glyphs
1282 on GUI frames.
1283 (produce_special_glyphs): Move here from term.c.
1285 * term.c (produce_special_glyphs): Move to xdisp.c.
1287 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
1288 section.
1290 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
1292 * xdisp.c (display_line): Avoid warning about implicit declaration
1293 of FRAME_FONT.
1295 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
1297 * lisp.h: Remove empty conditional.
1299 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
1301 * lread.c (load_path_check): Now static.
1303 Fix some minor --with-ns problems found by static checking.
1304 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
1305 (x_set_font) [!HAVE_X_WINDOWS]:
1306 * image.c (xpm_load_image) [HAVE_NS]:
1307 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
1308 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
1309 Remove unused local.

1317 * xfaces.c (FRAME_X_FONT_TABLE):
1318 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
1320 2012-07-07 Glenn Morris <rgm@gnu.org>
1322 * lread.c (load_path_check): New function, split from init_lread.
1323 (init_lread): Reorganize. Motivation:
1324 If EMACSLOADPATH is set, check/warn about that rather than the
1325 defaults, which we are not going to use. Hence we can remove
1326 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
1327 Don't warn if site-lisp directories are missing.
1328 If not installed, start from a blank load-path, since
1329 PATH_LOADSEARCH refers to the eventual installation directories.
1331 2012-07-07 Eli Zaretskii <eliz@gnu.org>
1333 Support truncation and continuation glyphs on GUI frames, when
1334 fringes are disabled. (Bug#11832)
1335 * xdisp.c (init_iterator): Get dimensions of truncation and
1336 continuation glyphs even if on GUI frames. Adjust
1337 it->last_visible_x on GUI frames when the left or right fringes,
1338 or both, are absent.
1339 (start_display, move_it_in_display_line_to): Handle the case of a
1340 GUI frame without a fringe to display continuation or truncation
1341 glyphs.
1342 (insert_left_trunc_glyphs): Support GUI frames: make sure
1343 truncation glyphs overwrite enough glyphs from the current line to
1344 have sufficient space in pixels.
1345 (display_line): Support truncation and continuation glyphs on GUI
1346 frames. If some spare pixels are left on the line after inserting
1347 the truncation glyphs, fill that space with a stretch glyph of a
1348 suitably computed width.
1350 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
1351 produce_glyphs, to support GUI sessions.
1353 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
1355 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
1357 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).

1360 This works better on hosts where time_t is unsigned, and where
1361 float-time is applied to the (negative) difference between two times.
1362 * editfns.c (decode_time_components): Last arg is now double *,
1363 not int *, and means to store all the result as a double, without
1364 worrying about whether the seconds part fits in time_t.
1365 All callers changed.
1366 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
1367 All callers changed.
1368 (Ffloat_time): Do not fail merely because the specified time falls
1369 outside of time_t range.
1371 2012-07-07 Glenn Morris <rgm@gnu.org>
1373 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

1393 * xfont.c (compare_font_names): Redo to omit the need for casts.
1395 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
1397 * xfns.c (Fx_change_window_property): Doc fix.
1398 * w32fns.c (Fx_change_window_property): Doc fix.
1400 * w32fns.c (Fx_window_property): Accept the same arguments as the
1401 X Windows version. Doc fix.
1402 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
1404 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
1405 Eli Zaretskii <eliz@gnu.org>
1407 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
1408 Windows-specific code from nt/config.nt moved here.
1409 Obsolete settings removed.
1411 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1413 * process.c: Avoid unnecessary calls to gettime.
1414 (wait_reading_process_output): Don't get the time of day
1415 when gobbling data immediately and not waiting, as there's no need
1416 for it in that case. This removes a FIXME.
1418 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
1420 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
1421 is defined (Bug#11768).
1423 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1425 Fix marker debugging code.
1426 * marker.c (byte_char_debug_check): Do not perform the check
1427 if buffer is not multibyte.
1428 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
1429 Call byte_char_debug_check with correct arguments.
1431 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1433 Compile marker debugging code only if ENABLE_CHECKING is defined.
1434 * marker.c (byte_char_debug_check, count_markers):
1435 Use only if ENABLE_CHECKING is defined.
1436 (byte_debug_flag): Remove.
1437 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
1438 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
1440 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1442 Avoid code repetition in marker-related functions.
1443 * marker.c (attach_marker): New function.
1444 (Fset_marker, set_marker_restricted, set_marker_both)
1445 (set_marker_restricted_both): Use it.
1446 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
1447 Consistently rename charno to charpos.
1448 (marker_position): Add eassert.
1449 (marker_byte_position): Convert to eassert.
1451 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

1465 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
1466 (save_restriction_save): Use build_marker.
1467 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
1468 * window.c (save_window_save): Likewise.
1470 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1472 Do not use Fdelete_overlay in delete_all_overlays
1473 to avoid redundant calls to unchain_overlay.
1474 * buffer.c (drop_overlay): New function.
1475 (delete_all_overlays, Fdelete_overlay): Use it.
1476 * minibuf.c (get_minibuffer): Fix comment.
1478 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1480 Port to OpenBSD 5.1 amd64.
1481 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
1482 This is needed for OpenBSD, and should be harmless on all BSD systems.
1483 Also, include <sys/sysctl.h>, as it should be available on all
1484 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
1485 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
1486 use p_pid member, not kp_proc.pid.
1488 2012-07-06 Glenn Morris <rgm@gnu.org>
1490 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
1492 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
1494 More xmalloc and related cleanup.

1503 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
1504 * xterm.c:
1505 Omit needless casts involving void * pointers and allocation.
1506 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
1507 as the former is more robust if P's type is changed.
1508 Prefer xzalloc to xmalloc + memset 0.
1509 Simplify malloc-or-realloc to realloc.
1510 Don't worry about xmalloc returning a null pointer.
1511 Prefer xstrdup to xmalloc + strcpy.
1512 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
1513 growing it.
1514 * keyboard.c (apply_modifiers_uncached): Prefer local array to
1515 alloca of a constant.
1517 2012-07-05 Eli Zaretskii <eliz@gnu.org>
1519 * xdisp.c (display_line): Fix horizontal pixel coordinates when
1520 hscroll is larger than the line width. Fixes long and futile
1521 looping inside extend_face_to_end_of_line (on a TTY) producing
1522 glyphs that are not needed and thrown away.
1524 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
1526 * marker.c (set_marker_restricted_both): Simplify by using
1527 clip_to_bounds.
1529 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
1531 * editfns.c (region_limit): Simplify by using clip_to_bounds.
1533 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>

1536 not defined (Bug#11768).
1537 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
1538 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
1539 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
1540 followed by gtk_box_set_homogeneous (Bug#11768).
1541 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
1542 (update_theme_scrollbar_width, xg_create_scroll_bar):
1543 Use gtk_scrollbar_new (Bug#11768).
1544 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
1545 (is_box_type): New function (Bug#11768).
1546 (xg_tool_item_stale_p): Call is_box_type.
1547 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
1548 with default display (Bug#11768).
1550 2012-07-05 Eli Zaretskii <eliz@gnu.org>
1552 * xdisp.c (window_hscroll_limited): New function.
1553 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
1554 coordinates when window's hscroll is set to insanely large
1555 values. (Bug#11857)
1557 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
1559 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

1618 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
1620 * fileio.c (time_error_value): Check the right error number.
1621 Problem reported by Troels Nielsen in
1622 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
1624 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1626 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
1627 This should be fixed in a better way; see Eli Zaretskii in
1628 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
1629 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
1631 * fileio.c (time_error_value): Rename from special_mtime.
1632 The old name's problems were noted by Eli Zaretskii in
1633 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
1635 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
1636 This variable's comment says Emacs needs at least one GDB-visible
1637 symbol of type enum pvec_type, to work around GDB problems.
1638 The symbol's value doesn't matter.
1640 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
1641 that causes compilation to fail on pre-C99 compilers.
1643 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
1645 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

1648 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
1650 * buffer.c (init_buffer_once): Fix initialization of
1651 headers for buffer_defaults and buffer_local_symbols.
1652 Reported by Juanma Barranquero <lekktu@gmail.com>.
1654 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
1656 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
1657 * lisp.h (enum pvec_type): Use fewer bits.
1658 (PSEUDOVECTOR_SIZE_BITS): New constant.
1659 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
1660 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
1661 change in pvec_type.

1668 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
1669 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
1670 (sweep_vectors): Use it. Use local var `total_bytes' instead of
1671 abusing vector->header.next.nbytes.
1672 (live_vector_p): Use PVEC_TYPE.
1673 (mark_object): Adapt code to extract pvectype. Use switch.
1675 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1677 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
1678 Tighten new eassert a bit.
1680 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
1682 Fix compilation with --enable-gcc-warnings and -O1
1683 optimization level.
1684 * doprnt.c (doprnt): Change type of tem to int, initialize
1685 to avoid compiler warning. Add eassert.
1686 * search.c (simple_search): Initialize match_byte to avoid
1687 compiler warning. Add eassert.
1689 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1691 Avoid weird behavior with large horizontal scrolls.
1692 Without this change, for example, large hscroll values would
1693 mess up Emacs's display on Fedora 15 x86, presumably due to
1694 overflows in int calculations in the display code.
1695 Also, if buffers had long lines, Emacs would freeze.
1696 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
1697 (set_window_hscroll): New function, containing the old guts of
1698 Fset_window_hscroll. Return the clipped value.
1699 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
1700 This avoids the need to check against PTRDIFF_MAX.
1702 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
1704 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
1706 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
1708 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1710 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
1711 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
1712 since GCC 4.4.6 issues a bogus warning for them.
1714 Fix bugs in file timestamp newness comparisons.
1715 * fileio.c (Ffile_newer_than_file_p):
1716 * lread.c (Fload): Use full timestamp resolution of files,
1717 not just the 1-second resolution, so that files that are only
1718 slightly newer still count as newer.
1719 * fileio.c (Ffile_newer_than_file_p): Don't assume file
1720 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
1722 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
1724 * fileio.c: Improve handling of file time marker. (Bug#11852)

1731 * fileio.c (Finsert_file_contents): Properly handle st_mtime
1732 marker for non-existing file. (Bug#11852)
1734 2012-07-03 Glenn Morris <rgm@gnu.org>
1736 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
1737 and did not make it into globals.h).
1739 2012-07-03 Tom Tromey <tromey@redhat.com>

1783 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
1785 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
1786 values which aren't power of 2.
1787 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro. Verify
1788 it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
1789 accordingly.
1791 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
1793 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
1795 * alloc.c (mark_object): Revert part of last patch to use `switch'.
1797 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
1799 * alloc.c (allocate_vector_block): Remove redundant
1800 calls to mallopt if DOUG_LEA_MALLOC is defined.
1801 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
1802 avoid calls to mallopt if zero_vector is returned.
1804 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
1806 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
1807 is enabled, avoid dereferencing NULL current_sblock if
1808 running undumped.
1810 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
1812 Cleanup basic buffer management.
1813 * buffer.h (struct buffer): Change layout to use generic vector
1814 marking code. Fix some comments. Change type of 'clip_changed'
1815 to bitfield. Remove unused #ifndef old.
1816 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
1817 (GET_OVERLAYS_AT): Fix indentation.
1818 (for_each_per_buffer_object_at): New macro.
1819 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
1820 (Fbuffer_local_variables): Use it.
1821 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
1822 * alloc.c (allocate_buffer): Adjust to match new layout of
1823 struct buffer. Fix comment.
1824 (mark_overlay): New function.
1825 (mark_buffer): Use it. Use mark_vectorlike to mark normal
1826 Lisp area of struct buffer.
1827 (mark_object): Use it. Adjust marking of misc objects
1828 and related comments.
1830 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
1832 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
1833 wrapper that is not needed because the wrapped code is a no-op (zero
1834 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
1835 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
1837 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
1839 * alloc.c (mark_buffer): Simplify. Remove prototype.
1840 (mark_object): Add comment. Reorganize marking of vector-like
1841 objects. Use CHECK_LIVE for all vector-like objects except buffers
1842 and subroutines when GC_CHECK_MARKED_OBJECTS is defined. Avoid
1843 redundant calls to mark_vectorlike for bool vectors.
1845 2012-06-30 Glenn Morris <rgm@gnu.org>
1847 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
1849 * epaths.in (PATH_SITELOADSEARCH): New.
1850 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
1851 This is rather than relying on --enable-locallisppath elements
1852 having "site-lisp" in their names. (Bug#10208#25, 11658)
1854 2012-06-30 Eli Zaretskii <eliz@gnu.org>
1856 * w32proc.c (sys_select): Accept and ignore one more argument.
1858 * w32.c (emacs_gnutls_pull): Call select with one more argument.
1860 * sysselect.h [DOS_NT]: Don't include sys/select.h.
1861 (pselect) [!MS_DOS]: Redirect to sys_select.
1863 * sysdep.c: Don't include dos.h and dosfns.h.
1865 * process.c (sys_select):
1866 * msdos.c (sys_select): Accept one more argument and ignore it.
1868 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
1869 adapt data types and code to that.
1871 * dosfns.c:
1872 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
1873 which clashes with the gnulib function of the same name.
1875 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
1877 * font.c (font_style_to_value, font_style_symbolic)
1878 (font_prop_validate_style): Add type checks for values in
1879 font_style_table.
1881 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
1882 argument.
1883 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
1884 uses.
1886 2012-06-29 Eli Zaretskii <eliz@gnu.org>
1888 * xdisp.c (try_window_id): Undo last change.
1890 * w32.c (getwd): Adjust commentary about startup_dir.
1891 (init_environment): Always call sys_access, even in non-MSVC
1892 builds. Don't chdir to the directory of the Emacs executable.
1893 This undoes code from 1997 which was justified by the need to
1894 "avoid conflicts when removing and renaming directories". But its
1895 downside was that every relative file name was being interpreted
1896 relative to the directory of the Emacs executable, which can never
1897 be TRT. In particular, it broke sys_access when called with
1898 relative file names.
1899 (sys_access): Map GetLastError to errno.
1901 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
1903 * window.h (struct window): Change type of 'fringes_outside_margins'
1904 to bitfield. Fix comment. Adjust users accordingly.
1905 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
1906 Adjust comment.
1907 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
1908 to ptrdiff_t.
1910 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
1912 * gnutls.c (emacs_gnutls_handshake):
1913 Add QUIT to make the loop interruptible.
1915 2012-06-29 Glenn Morris <rgm@gnu.org>
1917 * charset.c (init_charset): Make lack of etc/charsets fatal.
1919 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
1921 * editfns.c (region_limit): Fix type mismatch.
1923 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
1925 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
1926 undefined. Convert from xassert to eassert.
1927 * nsmenu.m: Convert from xassert to eassert.
1928 * nsterm.m: Likewise.
1930 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
1932 * editfns.c (region_limit): Clip to narrowing (bug#11770).
1934 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
1936 Avoid integer overflow on scroll-left and scroll-right.
1937 * window.c (HSCROLL_MAX): New macro.
1938 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
1939 overflow when requested scroll falls outside ptrdiff_t range.
1941 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
1943 * window.h (struct window): Change type of 'hscroll',
1944 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
1945 'last_modified' and 'last_overlay_modified' to EMACS_INT.
1946 Adjust users accordingly.
1947 * xdisp.c (try_cursor_movement): Replace type check with eassert.
1948 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
1949 from EMACS_INT to ptrdiff_t.
1950 (make_window): Omit redundant initialization.
1952 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
1954 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
1956 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
1958 * window.h (struct window): Change type of 'use_time' and
1959 'sequence_number' from Lisp_Object to int.
1960 * frame.c (make_frame): Adjust users accordingly.
1961 * print.c (print_object): Likewise.
1962 * window.c (select_window, Fwindow_use_time, make_parent_window)
1963 (make_window): Likewise.
1965 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
1967 * dispextern.h (GLYPH_DEBUG): Now defined in config.h if
1968 enabled with --enable-checking=[all,glyphs] configure option.
1969 Fix GLYPH_DEBUG usage assuming that it may be undefined,
1970 adjust comments accordingly.
1971 * dispnew.c: Fix GLYPH_DEBUG usage assuming that it may be
1972 undefined, adjust comments accordingly.

2012 2012-06-27 Stefan Monnier <monnier@iro.umontreal.ca>
2014 * fns.c (maybe_resize_hash_table): Output message when growing the
2015 purify-hashtable.
2017 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
2019 * alloc.c (allocate_string_data): Remove dead code.
2020 * xsettings.c (XSETTINGS_FONT_NAME): Move under HAVE_XFT to
2021 avoid GCC warning about unused macro.
2023 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
2025 * alloc.c (allocate_string): Omit intervals initialization.
2026 * alloc.c (make_uninit_multibyte_string): Initialize intervals
2027 as in make_pure_string and make_pure_c_string.
2029 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>

2046 2012-06-26 John Wiegley <johnw@newartisans.com>
2048 * unexmacosx.c (copy_data_segment): Add two section names used
2049 on Mac OS X Lion: __mod_init_func and __mod_term_func.
2051 * alloc.c (mark_memory): Do not check with -faddress-sanitizer
2052 when building with Clang.
2054 2012-06-26 Stefan Monnier <monnier@iro.umontreal.ca>
2056 * eval.c (Fapply): Allow calling it with a single argument.
2058 2012-06-26 Eli Zaretskii <eliz@gnu.org>
2060 * s/ms-w32.h (strcasecmp, strncasecmp) [_MSC_VER]: Redirect to
2061 _stricmp and _strnicmp.
2062 (HAVE_STRCASECMP, HAVE_STRNCASECMP): Define to 1.
2064 2012-06-26 Dmitry Antipov <dmantipov@yandex.ru>
2066 * alloc.c (allocate_window): Zero out non-Lisp part of newly
2067 allocated window.
2068 (allocate_process): Likewise for new process.
2069 (allocate_terminal): Change to use offsetof.
2070 (allocate_frame): Likewise.

2077 2012-06-26 Dmitry Antipov <dmantipov@yandex.ru>
2079 * term.c (delete_tty): Remove redundant call to memset.
2081 2012-06-26 Dmitry Antipov <dmantipov@yandex.ru>
2083 * alloc.c: Remove build_string.
2084 * lisp.h: Define build_string as static inline. This provides
2085 a better opportunity to optimize away calls to strlen when the
2086 function is called with compile-time constant argument.
2087 * image.c (imagemagick_error): Convert to build_string.
2088 * w32proc.c (sys_spawnve): Likewise.
2089 * xterm.c (x_term_init): Likewise.
2091 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
2093 Use sprintf return value instead of invoking strlen on result.
2094 In the old days this wasn't portable, since some sprintf
2095 implementations returned char *. But they died out years ago and
2096 Emacs already assumes sprintf returns int.
2097 Similarly for float_to_string.
2098 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
2099 * ccl.c (ccl_driver):
2100 * character.c (string_escape_byte8):
2101 * data.c (Fnumber_to_string):
2102 * doprnt.c (doprnt):
2103 * print.c (print_object):
2104 * xdisp.c (message_dolog):
2105 * xfns.c (syms_of_xfns):
2106 Use sprintf or float_to_string result to avoid need to call strlen.
2107 * data.c (Fnumber_to_string):
2108 Use make_unibyte_string, since the string must be ASCII.
2109 * lisp.h, print.c (float_to_string): Now returns int length.
2110 * term.c (produce_glyphless_glyph):
2111 Use sprintf result rather than recomputing it.
2113 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
2114 * Makefile.in (ALL_CFLAGS):
2115 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
2116 * gmalloc.c, regex.c: Include <config.h> unconditionally.
2118 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
2120 * dispextern.h (xstrcasecmp): Define to library function
2121 strcasecmp if available.
2122 * xfaces.c: Do not use xstrcasecmp if strcasecmp is available.
2124 2012-06-25 Andreas Schwab <schwab@linux-m68k.org>
2126 * keyboard.c (menu_bar_items, menu_bar_item, read_key_sequence):
2127 Avoid comma operator.
2128 * menu.c (push_submenu_start, push_submenu_end)
2129 (push_left_right_boundary, push_menu_pane): Likewise.
2130 * msdos.c (dos_rawgetc): Likewise.
2132 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
2134 * xfns.c (xic_create_fontsetname): Remove redundant calls
2135 to memset.
2137 2012-06-25 Paul Eggert <eggert@cs.ucla.edu>
2139 * gtkutil.c (get_utf8_string): Remove redundant assignment.
2140 sprintf already null-terminates its output.
2142 * xfns.c (x_window): Remove redundant cast.
2144 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
2146 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
2147 `const char *' to `char *' to avoid compiler warning.
2149 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
2151 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
2152 instead of truncating it to 63 (admittedly a generous limit).
2154 * process.c: Fix spelling and caps in comments.
2156 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
2158 * emacs.c (setpgrp): Remove definition, unused.
2159 * sysdep.c (setpgrp): Remove definition, not used in this file.
2161 2012-06-24 Juanma Barranquero <lekktu@gmail.com>
2163 * makefile.w32-in: Update dependencies.
2165 2012-06-24 Eli Zaretskii <eliz@gnu.org>
2167 * makefile.w32-in (TIMESPEC_H): Remove nt/inc/sys/time.h.
2168 (SYSTIME_H): Add nt/inc/sys/time.h.
2170 * systime.h [WINDOWSNT]: Include sys/time.h.
2172 * s/ms-w32.h (struct timespec): Definition moved from
2173 nt/inc/sys/time.h. Suggested by Paul Eggert <eggert@cs.ucla.edu>.
2175 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
2177 Switch from NO_RETURN to C11's _Noreturn (Bug#11750).

2199 * undo.c (user_error):
2200 * unexmacosx.c (unexec_error):
2201 * xterm.c (x_ins_del_lines, x_delete_glyphs):
2202 Use _Noreturn rather than NO_RETURN.
2203 No need for separate decl merely because of _Noreturn.
2204 * sound.c (sound_warning, parse_sound):
2205 Remove unnecessary forward decls.
2207 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
2209 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
2210 * lisp.h (WAIT_READING_MAX): New macro.
2211 * dispnew.c (Fsleep_for, sit_for):
2212 * keyboard.c (kbd_buffer_get_event):
2213 * process.c (Faccept_process_output):
2214 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
2215 This improves on the previous patch, which introduced a bug
2216 when time_t is unsigned and as wide as intmax_t.
2217 See <http://bugs.gnu.org/9000#51>.
2219 2012-06-23 Eli Zaretskii <eliz@gnu.org>
2221 * dispnew.c (sit_for, Fsleep_for):
2222 * keyboard.c (kbd_buffer_get_event):
2223 * process.c (Faccept_process_output): Avoid compiler warnings when
2224 comparing a 32-bit time_t with a 64-bit INTMAX_MAX.
2226 2012-06-23 Juanma Barranquero <lekktu@gmail.com>
2228 * makefile.w32-in: Update dependencies.
2230 * w32.c (ltime): Add return type and declare static.
2231 (w32_get_internal_run_time): Remove usused variable `time_100ns'.
2233 2012-06-23 Paul Eggert <eggert@cs.ucla.edu>
2235 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
2236 Privately reported by Herbert J. Skuhra.
2237 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
2238 All uses changed.
2239 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
2240 not make_lisp_timeval, when the argument is of type EMACS_TIME.
2242 2012-06-23 Eli Zaretskii <eliz@gnu.org>
2244 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
2245 last argument of make_unibyte_string.
2247 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
2248 language ID in the event parameters.
2250 * w32term.c (w32_read_socket): Put the new keyboard codepage into
2251 event.code, not the obscure "character set ID".
2253 2012-06-23 Chong Yidong <cyd@gnu.org>
2255 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.
2257 2012-06-23 Eli Zaretskii <eliz@gnu.org>
2259 Fix the MS-Windows build broken by 2012-06-22T21:17:42Z!eggert@cs.ucla.edu.
2260 * w32.c (fdutimens): New function.
2262 * w32proc.c (sys_select): Adapt to change in the EMACS_TIME type.
2264 * s/ms-w32.h (pselect): Redirect to sys_select.
2266 * sysselect.h [WINDOWSNT]: Don't include sys/select.h.
2268 * ralloc.c (r_alloc_inhibit_buffer_relocation): Fix stupid thinko
2269 in the logic of incrementing and decrementing the value of
2270 use_relocatable_buffers.
2272 2012-06-23 Paul Eggert <eggert@cs.ucla.edu>
2274 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
2275 Privately reported by Herbert J. Skuhra.
2276 [__FreeBSD__]: Remove "*/" typo after "#include".
2277 (timeval_to_EMACS_TIME) [__FreeBSD__]: New static function.
2278 (TIMEVAL) [__FreeBSD__]: Now a static function rather than a macro.
2279 (TIMEVAL, system_process_attributes) [__FreeBSD__]:
2280 Don't assume EMACS_TIME and struct timeval are the same type.
2282 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
2284 Support higher-resolution time stamps (Bug#9000).
2285 The time stamps are only nanosecond-resolution at the C level,
2286 since that's the best that any real-world system supports now.
2287 But they are picosecond-resolution at the Lisp level, as that's
2288 easy, and leaves room for future OS improvements.
2290 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
2291 (LIBES): Use it.
2293 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
2294 Don't get current time unless it's needed.
2296 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
2297 now provides it if it's absent.
2298 (start_atimer): Port to higher-res time stamps.
2299 Check for time stamp overflow. Don't get current time more
2300 often than is needed.
2302 * buffer.h (struct buffer): Buffer modtime now has high resolution.
2303 Include systime.h, not time.h.
2304 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.

2324 (make_time): Now static.
2325 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
2326 Report an error if the time is invalid, rather than having the caller
2327 do that.
2329 * fileio.c: Include <stat-time.h>
2330 (Fcopy_file): Copy higher-resolution time stamps.
2331 Prefer to set the time stamp via a file descriptor if that works.

2348 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
2349 Port to higher-resolution time stamps. Do not assume time_t is signed.
2350 (decode_timer): New function. Timers are now vectors of length 9,
2351 not 8, to accommodate the picosecond component.
2352 (timer_check_2): Use it.
2354 * nsterm.m (select_timeout, timeval_subtract): Remove.
2355 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
2356 as they're a bit more accurate and handle overflow better.

2358 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
2359 * nsterm.h (ns_select): Adjust prototype.
2361 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes

2371 * process.h (struct Lisp_Process.read_output_delay):
2372 Now counts nanoseconds, not microseconds.
2373 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
2374 EMACS_HAS_USECS.
2375 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)

2377 Port to ns-resolution time stamps.
2378 (Faccept_process_output, wait_reading_process_output):
2379 Check for time stamp overflow. Do not assume time_t is signed.
2380 (select_wrapper): Remove; we now use pselect.
2381 (Fprocess_attributes): Now generates ns-resolution time stamps.
2383 * sysdep.c: Include utimens.h. Don't include utime.h
2384 or worry about struct utimbuf; gnulib does that for us now.
2385 (gettimeofday): Remove; gnulib provides a substitute.
2386 (make_timeval): New function.
2387 (set_file_times): Now sets ns-resolution time stamps.
2388 New arg FD; all uses changed.
2389 (time_from_jiffies, ltime_from_jiffies, get_up_time)

2391 Now returns ns-resolution time stamp. All uses changed.
2392 Check for time stamp overflow.
2394 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
2395 provides a substitute now.
2397 * systime.h: Include timespec.h rather than sys/time.h and time.h,
2398 since it guarantees struct timespec.
2399 (EMACS_TIME): Now struct timespec, so that we can support
2400 ns-resolution time stamps.
2401 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
2402 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
2403 (EMACS_USECS): Remove.
2404 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
2405 so multiply the arg by 1000 before storing it.
2406 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
2407 New macros.

2415 (make_timeval, make_lisp_time, decode_time_components): New decls.
2416 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
2417 that it mishandled time_t overflow. You can't compare by subtracting!
2418 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
2419 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.

2426 in the undo buffer.
2427 (Fprimitive_undo): Use them when restoring time stamps.
2429 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
2430 (w32_get_internal_run_time):
2431 Port to higher-resolution Emacs time stamps.
2432 (ltime): Now accepts single 64-bit integer, as that's more convenient
2433 for callers.
2435 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
2437 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
2438 for compatibility with pselect. Support ns-resolution time stamps.
2440 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
2442 * xselect.c (wait_for_property_change, x_get_foreign_selection):
2443 Check for time stamp overflow, and support ns-resolution time stamps.
2445 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
2446 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
2447 (timeval_subtract): Remove; no longer needed.
2448 (XTflash, XTring_bell, x_wait_for_event):
2449 Port to ns-resolution time stamps. Don't assume time_t is signed.

2455 2012-06-22 Eli Zaretskii <eliz@gnu.org>
2457 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
2458 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
2459 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
2460 staticidx goes up to 1597 out of 1600 = 0x640.)
2462 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
2464 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
2465 Otherwise, the umask might be mistakenly 0 while handling input signals.
2467 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
2469 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

2475 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
2476 access to `contents' member of Lisp_Vector objects with AREF and ASET
2477 where appropriate.
2479 2012-06-19 Chong Yidong <cyd@gnu.org>
2481 * frame.c (delete_frame): When selecting a frame on a different
2482 text terminal, do not alter the terminal's top-frame.

2485 frame's selected window and its terminal's top-frame.
2486 (unwind_format_mode_line): Restore them.
2487 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
2488 Callers changed.
2489 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
2490 since tty frames can be explicitly named.
2491 (prepare_menu_bars): Likewise.
2493 * term.c (Ftty_top_frame): New function.
2495 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
2497 Port byte-code-meter to modern targets.
2498 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
2499 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
2500 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
2501 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
2502 (METER_1, METER_2): Simplify.
2504 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
2506 * data.c (Fdefalias): Return `symbol' (bug#11686).
2508 2012-06-18 Martin Rudalics <rudalics@gmx.at>
2510 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
2511 gets killed during executing of this function (Bug#11665).
2512 Try to always return Qt when the buffer has been actually killed.
2513 (Vkill_buffer_query_functions): In doc-string say that functions
2514 run by this hook should not change the current buffer.
2516 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
2518 Fix recently-introduced process.c problems found by static checking.
2519 * process.c (write_queue_push, write_queue_pop, send_process):

2536 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
2538 * lisp.h (eassert): Assume C89 or later.
2539 This removes the need for CHECK.
2540 (CHECK): Remove. Its comments about always evaluating its
2541 argument were confusing, as 'eassert' typically does not evaluate
2542 its argument.
2544 * coding.c (produce_chars): Use ptrdiff_t, not int.
2546 * xterm.c (x_draw_underwave): Check for integer overflow.
2547 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

2640 * xdisp.c (set_cursor_from_row): Don't dereference glyphs_end.
2641 If all the glyphs of the glyph row came from strings, and we have no
2642 cursor positioning clues, put the cursor on the first glyph of the
2643 row.
2644 (handle_face_prop): Use chunk-relative overlay string index when
2645 indexing into it->string_overlays array. (Bug#11653)

2661 2012-06-14 Paul Eggert <eggert@cs.ucla.edu>
2663 * .gdbinit (xgetint): Fix recently-introduced paren typo.
2664 Assume USE_2_TAGS_FOR_INTS.

2667 Simplify lisp.h in minor ways that should not affect code.
2668 * lisp.h (USE_2_TAGS_FOR_INTS): Remove, as it was always defined.
2669 (LISP_INT_TAG, case_Lisp_Int, LISP_STRING_TAG, LISP_INT_TAG_P)
2670 (LISP_INT1_TAG, enum Lisp_Type, XINT, XUINT, make_number):

2690 * lisp.h (Lisp_Object) [CHECK_LISP_OBJECT_TYPE]: Define as struct
2691 instead of union.
2692 (XLI, XIL): Define.

2699 * frame.c (delete_frame): Remove outdated comment.
2700 * w32fns.c (Fw32_register_hot_key): Use XLI instead of checking

2731 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
2732 code works fine either way, and efficiency is not a concern here,
2733 as the union type is for debugging, not for production.
2734 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
2735 Use an inline function on all platforms when using the union type,
2736 since this is simpler and 'static inline' can be used portably
2737 within Emacs now.
2738 (LISP_INITIALLY_ZERO): New macro.

2823 Without this change, (let ((§ 1)) (make-variable-buffer-local '§))
2824 would generate the diagnostic "Making \302\247 buffer-local while
2825 let-bound!".
2827 2012-06-08 Eli Zaretskii <eliz@gnu.org>
2829 * dispnew.c (showing_window_margins_p): Undo last change, which

2878 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
2880 * doprnt.c (doprnt): Truncate multibyte char correctly.
2881 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
2882 would mishandle a string argument "Xc" if X was a multibyte

2884 rather than including all of X.
2886 2012-06-06 Chong Yidong <cyd@gnu.org>
2888 * buffer.c (word_wrap): Doc fix.

2937 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
2938 Convert pctcpu and pctmem to Lisp float properly.
2939 Let the compiler fold better, as 100.0/0x8000 is exact.

2943 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
2944 cons_block.

2953 bitfields where appropriate, remove unused fields.
2954 * window.h (struct window): Remove unused 'last_mark_x' and
2955 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
2956 change it's type from Lisp_Object to bitfield.
2957 Change type of 'force_start', 'optional_new_start',
2958 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
2959 fields from Lisp_Object to bitfield. Adjust users accordingly.
2961 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
2963 Pacify gcc -Wdouble-precision when using Xaw.
2964 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
2965 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
2966 Use 'float' consistently, rather than 'float' in most places
2967 and 'double' in a couple of places.
2969 2012-05-31 Eli Zaretskii <eliz@gnu.org>
2971 * xdisp.c (handle_stop): Detect whether we have overlay strings
2972 loaded by testing it->current.overlay_string_index to be
2973 non-negative, instead of checking whether n_overlay_strings is
2974 positive. (Bug#11587)
2976 2012-05-31 Chong Yidong <cyd@gnu.org>
2978 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

2984 * search.c (search_buffer): Remove calls to
2985 r_alloc_inhibit_buffer_relocation, as it is now called by
2986 maybe_unify_char, which was the cause of relocation of buffer text
2987 in bug#11519.
2989 2012-05-31 Eli Zaretskii <eliz@gnu.org>
2991 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
2992 for the duration of call to load_charset, to avoid problems with
2993 callers of maybe_unify_char that access buffer text through C
2994 pointers.
2996 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
2997 decrement the inhibition flag, instead of just setting or
2998 resetting it.

3002 Remove obsolete '#define static' cruft.
3003 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
3004 This #undef was "temporary" in 2000; it is no longer needed
3005 now that '#define static' has gone away.
3006 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
3007 (gray_bitmap_bits): Remove; no longer needed.
3008 All uses replaced with definiens.

3016 Define only on platforms that need it.
3017 * emacs.c: Include <sys/gmon.h> when profiling.
3018 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
3019 (__executable_start): Remove decl, since lisp.h does it now.
3020 (safe_bcopy): Remove decl; no longer has that name.
3021 (main): Coalesce #if into single bit of code, for simplicity.
3022 Cast pointers to uintptr_t, since standard libraries want integers
3023 and not pointers.
3024 * lisp.h (__executable_start): New decl.
3026 2012-05-31 Glenn Morris <rgm@gnu.org>

3051 Do not create empty overlays with the evaporate property (Bug#9642).
3052 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
3053 Bug#9642, but explicitly check that the buffer the overlay would
3054 be moved to is live and rearrange lines to make sure that errors
3055 will not put the overlay in an inconsistent state.
3056 (Fdelete_overlay): Cosmetics.
3058 2012-05-28 Eli Zaretskii <eliz@gnu.org>
3060 * w32term.c (my_bring_window_to_top): New function.
3061 (x_raise_frame): Use handle returned by DeferWindowPos, which
3062 could be different from the original one.

3076 to not catch an out-of-range value.
3078 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
3080 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

3096 the others were already declared.
3098 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
3099 before checking whether it's out of range. Put the check inside
3100 eassert. See
3101 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
3103 2012-05-27 Ken Brown <kbrown@cornell.edu>

3111 defined on ralloc.c.
3113 * buffer.c [REL_ALLOC]: Remove prototypes of

3115 they are now on lisp.h.
3117 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
3119 * search.c (search_buffer): Use it to inhibit relocation of buffer
3120 text while re_search_2 is doing its job, because re_search_2 is
3121 passed C pointers to buffer text. (Bug#11519)
3123 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
3124 Update value to 24.
3126 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator

3128 the values of it->max_ascent and it->max_descent found for the
3129 entire line.
3130 (pos_visible_p): Revert the comparison against bottom_y to what it
3131 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
3132 (Bug#11464)
3134 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3136 Fix coding-related core dumps with gcc -ftrapv.
3137 The code was computing A - B, where A and B are pointers, and B is
3138 random garbage. This can lead to core dumps on platforms that
3139 have special pointer registers, and it also leads to core dumps on
3140 x86-64 when compiled with gcc -ftrapv. The fix is to compute
3141 A - B only when B is initialized properly.
3142 * coding.c (coding_set_source, coding_set_destination): Return void.
3143 (coding_change_source, coding_change_destinations): New functions,
3144 with the old behaviors of coding_set_source and coding_set_destination.
3145 All callers that need an offset changed to use these new functions.

3158 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
3159 New functions.
3160 (initialize_w32_display): Initialize mouse-highlight data.
3162 * w32inevt.c: Include termchar.h and window.h.
3163 (do_mouse_event): Support mouse-autoselect-window. When the mouse
3164 moves, call note_mouse_highlight. If help_echo changed, call
3165 gen_help_event to produce help-echo message in the echo area.
3166 Call clear_mouse_face if mouse_face_hidden is set in the mouse
3167 highlight info.
3169 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3171 * lread.c (read1): Simplify slightly to avoid an overflow warning
3172 with GCC 4.7.0 on x86-64.
3174 2012-05-26 Eli Zaretskii <eliz@gnu.org>
3176 * bidi.c (bidi_mirror_char): Revert last change: an int is
3177 definitely wide enough here.

3188 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
3189 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
3190 (mark_vectorlike):
3191 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3192 (allocate_pseudovector):
3193 Use int, not EMACS_INT, where int is wide enough.
3194 (inhibit_garbage_collection, Fgarbage_collect):
3195 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3196 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
3197 int might not be wide enough.

3213 (Foverlay_recenter, last_overlay_modification_hooks_used)
3214 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
3215 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3216 (validate_region): Omit unnecessary test for b <= e,
3217 since that's guaranteed by the previous test.
3218 (adjust_overlays_for_delete): Avoid pos + length overflow.
3219 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
3220 (report_overlay_modification):
3221 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3222 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
3223 Omit pointer cast, which isn't needed anyway, and doesn't work
3224 after the EMACS_INT -> ptrdiff_t change.
3225 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
3226 * buffer.h: Adjust decls to match defn changes elsewhere.

3231 not int, to avoid needless 32-bit limit on 64-bit hosts.
3232 (exec_byte_code): Use tighter memory-full test, one that checks
3233 for alloca overflow. Don't compute the address of the object just
3234 before an array, as that's not portable. Use EMACS_INT, not
3235 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
3236 * callint.c (Fcall_interactively):
3237 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

3250 (casify_object): Avoid integer overflow when overallocating buffer.
3251 * casetab.c (set_identity, shuffle): Prefer int to unsigned when

3254 * category.h (CATEGORYP): Don't assume arg is nonnegative.
3255 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
3256 integers are now checked earlier. All uses replaced with XINT.
3257 (ccl_driver):
3258 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3259 For CCL_MapSingle, check that content and value are in int range.

3261 Check that Vcode_version_map_vector is a vector.
3262 (resolve_symbol_ccl_program): Check that vector header is in range.
3263 Always copy the vector, so that we can check its contents reliably
3264 now rather than having to recheck each instruction as it's being
3265 executed. Check that vector words fit in 'int'.
3266 (ccl_get_compiled_code, Fregister_ccl_program)
3267 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
3268 program indexes, to avoid needless 32-bit limit on 64-bit hosts.

3270 contents are in range.
3271 (Fccl_execute_on_string): Check that status is in range.
3272 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
3273 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
3274 Accept and return EMACS_INT, not int, because callers can pass values

3281 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

3294 Don't rely on undefined behavior with signed left shift overflow.
3295 Don't assume unsigned int fits into fixnum, or that fixnum fits
3296 into unsigned int. Don't require max_code to be a valid fixnum;
3297 that's not true for gb10830 4-byte on a 32-bit host. Allow
3298 invalid_code to be a cons, for the same reason. Require code_offset
3299 to be a character. Avoid int overflow if max_char is close
3300 to INT_MAX.
3301 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
3302 this is intended anyway and avoids some undefined behavior.
3303 (load_charset_map): Pass unsigned, not int, as 2nd arg of
3304 INDEX_TO_CODE_POINT, as that's what it expects.
3305 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
3306 * charset.h (DECODE_CHAR): Return int, not unsigned;
3307 this is what was intended anyway, and it avoids undefined behavior.
3308 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
3309 integer-overflow issues.
3310 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
3311 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
3312 where the argument is EMACS_INT, and this behavior is not intended.
3313 * chartab.c (Fmake_char_table, Fset_char_table_range)
3314 (uniprop_get_decoder, uniprop_get_encoder):
3315 Don't assume fixnum fits in int.
3316 * cmds.c (move_point): New function, that does the gist of
3317 Fforward_char and Fbackward_char, but does so while checking
3318 for integer overflow more accurately.
3319 (Fforward_char, Fbackward_char): Use it.
3320 (Fforward_line, Fend_of_line, internal_self_insert)
3321 (internal_self_insert):
3322 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

3924 (last_escape_glyph_face_id, last_glyphless_glyph_face_id):

3928 (get_next_display_element, next_element_from_display_vector):
3929 Use int, not EMACS_INT, when int is wide enough.
3930 (start_hourglass): Use duration_to_sec_usec to do proper
3931 overflow checking on durations.
3932 * xfaces.c (Fbitmap_spec_p):
3933 Check that fixnums are in proper range for system types.

3968 (x_send_client_event): Don't assume fixnum fits in int.
3969 * xterm.c (x_x_to_emacs_modifiers):
3970 Don't assume EMACS_INT overflows nicely into int.
3971 (x_emacs_to_x_modifiers): Use EMACS_INT, not int, because values
3972 may come from Lisp.
3973 (handle_one_xevent): NATNUMP can eval its arg twice.
3974 (x_connection_closed):
3975 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3976 * xterm.h: Adjust decls to match defn changes elsewhere.
3977 (struct scroll_bar): Use struct vectorlike_header
3978 rather than rolling our own approximation.
3979 (SCROLL_BAR_VEC_SIZE): Remove; not used.
3981 2012-05-25 Glenn Morris <rgm@gnu.org>
3983 * lisp.mk (lisp): Update for more files being compiled now.
3985 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
3987 * lread.c: Remove `read_pure' which makes no difference.
3988 (read_pure): Remove var.
3989 (unreadpure): Remove function.
3990 (readevalloop): Don't call read_list with -1 flag.
3991 (read1, read_vector): Don't test read_pure any more.
3992 (read_list): Simplify.
3994 * fileio.c, character.h: Minor style tweaks.
3996 2012-05-24 Dmitry Antipov <dmantipov@yandex.ru>
3998 * window.h (clip_changed): Remove useless declaration.
4000 2012-05-22 Juanma Barranquero <lekktu@gmail.com>
4002 * makefile.w32-in: Follow-up to 2012-05-22T16:20:27Z!eggert@cs.ucla.edu.
4003 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
4005 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
4007 Remove src/m/*.
4008 This directory predates autoconf and is no longer needed nowadays.
4009 Move its few remaining bits of functionality to where they're needed.
4010 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:
4011 * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:
4012 * m/template.h: Remove.
4013 * Makefile.in (M_FILE): Remove. All uses removed.
4014 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS):
4015 * lisp.h (USE_LSB_TAG):
4016 * mem-limits.h (EXCEEDS_LISP_PTR):
4017 Use VAL_MAX, not VALBITS, in #if.
4018 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
4019 (EMACS_UINT): Define unconditionally now.
4020 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
4021 (BITS_PER_EMACS_INT): New constants, replacing
4022 what used to be in config.h, but not useful in #if.
4023 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
4024 define them any more.
4025 (VAL_MAX): New macro.
4026 (VALMASK): Use it.
4027 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
4028 BITS_PER_EMACS_INT, in #if.
4029 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
4030 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
4031 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
4032 * s/ms-w32.h (DATA_START):
4033 Move here from removed file m/intel386.h.
4034 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
4035 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
4037 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
4039 Assume C89 or later.
4040 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
4041 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
4042 (xrealloc):
4043 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.

4045 * textprop.c, tparam.c (NULL): Remove.

4047 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
4048 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
4049 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
4050 * xterm.c (input_signal_count): Assume volatile works.
4052 2012-05-21 Ken Brown <kbrown@cornell.edu>
4054 * xgselect.c (xg_select): Fix first argument in call to 'select'
4055 (bug#11508).
4057 2012-05-20 Ken Brown <kbrown@cornell.edu>
4059 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
4060 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
4062 2012-05-19 Ken Brown <kbrown@cornell.edu>
4064 * xfns.c (x_in_use): Remove `static' qualifier.
4065 * xterm.h (x_in_use): Declare.
4066 * xgselect.c: Include xterm.h.
4067 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
4068 and `display_arg' (bug#9754).
4070 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
4072 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
4074 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
4075 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
4077 2012-05-18 Eli Zaretskii <eliz@gnu.org>
4079 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
4081 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
4082 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
4084 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
4085 reference to image_cache->refcount.
4086 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
4088 2012-05-17 Juri Linkov <juri@jurta.org>
4090 * search.c (Fword_search_regexp, Fword_search_backward)
4091 (Fword_search_forward, Fword_search_backward_lax)
4092 (Fword_search_forward_lax): Move functions to isearch.el
4093 (bug#10145, bug#11381).
4095 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
4097 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
4099 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
4101 * lread.c (init_obarray): Declare Qt and Qnil as special.
4103 2012-05-14 Glenn Morris <rgm@gnu.org>
4105 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
4106 Put "libexec" before "bin", for the sake of init_callproc_1.
4108 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
4110 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
4112 * unexaix.c: Port to more-recent AIX compilers.
4113 (report_error, report_error_1, make_hdr, copy_sym)
4114 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
4115 Make arguments const char *, not char *, to avoid violations of C
4116 standard and to fix some AIX warnings reported by Gilles Pion.
4118 2012-05-14 Eli Zaretskii <eliz@gnu.org>
4120 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
4121 already have overlays loaded.
4122 (handle_single_display_spec): Before returning without displaying
4123 fringe bitmap, synchronize the bidi iterator with the main display
4124 iterator, by calling iterate_out_of_display_property.
4125 (iterate_out_of_display_property): Detect buffer iteration by
4126 testing that it->string is a Lisp string.
4127 (get_next_display_element): When the current object is exhausted,
4128 and there's something on it->stack, call set_iterator_to_next to
4129 proceed with what's on the stack, instead of returning zero.
4130 (set_iterator_to_next): If called at the end of a Lisp string,
4131 proceed to consider_string_end without incrementing string
4132 position. Don't increment display vector index past the end of
4133 the display vector. (Bug#11417)
4134 (pos_visible_p): Don't report a position visible when move_it_to
4135 stopped at the last line of window, which happens to be scanned
4136 backwards by the bidi iteration. (Bug#11464)
4138 2012-05-14 Eli Zaretskii <eliz@gnu.org>
4140 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
4141 and right-margin display specs even if the spec is invalid or we
4142 are on a TTY, and thus unable to display on the fringes.
4143 That's because the text with the property will not be displayed anyway,
4144 so we need to signal to the caller that this is a "replacing"
4145 display spec. This fixes display when the spec is invalid or we
4146 are on a TTY.
4148 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
4150 * unexaix.c (make_hdr): Fix typo in prototype.
4151 This bug broke the build on AIX. Problem reported by Gilles Pion.
4153 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
4155 * keyboard.c (kbd_buffer_get_event): Read special events also in
4156 batch mode. (Bug#11415)
4158 2012-05-12 Glenn Morris <rgm@gnu.org>
4160 * ns.mk: Update for ns_appbindir no longer having trailing "/".
4162 2012-05-12 Eli Zaretskii <eliz@gnu.org>
4164 * lisp.mk (lisp): Add newcomment.elc.
4166 2012-05-12 Glenn Morris <rgm@gnu.org>
4168 * Makefile.in (MKDIR_P): New, set by configure.
4169 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
4171 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
4173 Remove unused function hourglass_started.
4174 * dispextern.h (hourglass_started):
4175 * w32fns.c (hourglass_started):
4176 * xdisp.c (hourglass_started): Remove.
4178 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
4180 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
4181 Update dependencies.
4183 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
4185 * xgselect.c (xg_select): Put maxfds+1 into a var.
4186 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
4188 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
4190 2012-05-10 Dave Abrahams <dave@boostpro.com>
4192 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
4193 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
4195 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
4197 * dbusbind.c (xd_registered_buses): New internal Lisp object.
4198 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
4199 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
4200 Initialize xd_registered_buses.
4202 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
4204 Untag more efficiently if USE_LSB_TAG.
4205 This is based on a proposal by YAMAMOTO Mitsuharu in
4206 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
4207 For an admittedly artificial (nth 8000 longlist) benchmark on
4208 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
4209 Emacs's overall text size by 1%.
4210 * lisp.h (XUNTAG): New macro.
4211 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
4212 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
4213 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
4214 * eval.c (Fautoload):
4215 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
4216 * frame.h (XFRAME): Use XUNTAG.
4218 Port recent dbusbind.c changes to 32-bit --with-wide-int.
4219 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
4220 Remove unportable assumptions about print widths of types like
4221 dbus_uint32_t.
4222 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
4223 intptr_t when converting between pointer and integer, to avoid GCC
4224 warnings about wrong width.
4226 2012-05-09 Eli Zaretskii <eliz@gnu.org>
4228 * w32proc.c (new_child): Force Windows to reserve only 64KB of
4229 stack for each reader_thread, instead of defaulting to 8MB
4230 determined by the linker. This avoids failures in creating
4231 subprocesses on Windows 7, see the discussion in this thread:
4232 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
4234 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
4236 Fix up display of the *Minibuf-0* buffer in the mini window.
4237 * keyboard.c (read_char): Don't clear the echo area if there's no
4238 message to clear.
4239 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
4240 contents of *Minibuf-0*) if there's no message displayed in its stead.
4242 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
4244 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
4245 batch mode.
4247 2012-05-06 Chong Yidong <cyd@gnu.org>
4249 * lisp.mk (lisp): Update.
4251 2012-05-05 Jim Meyering <meyering@redhat.com>
4253 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
4255 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
4257 * data.c (PUT_ERROR): New macro.
4258 (syms_of_data): Use it. Add new error type `user-error'.
4259 * undo.c (user_error): New function.
4260 (Fprimitive_undo): Use it.
4261 * print.c (print_error_message): Adjust print style for `user-error'.
4262 * keyboard.c (user_error): New function.
4263 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
4265 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
4267 Do not limit current-time-string to years 1000..9999.
4268 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
4269 (Fcurrent_time_string): Support any year that is supported by the
4270 underlying localtime representation. Don't use asctime, as it
4271 has undefined behavior for years outside the range -999..9999.
4273 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
4275 Fix race conditions involving setenv, gmtime, localtime, asctime.
4276 Without this fix, interrupts could mess up code that uses these
4277 nonreentrant functions, since setting TZ invalidates existing
4278 tm_zone or tzname values, and since most of these functions return
4279 pointers to static storage.
4280 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
4281 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
4282 Grow the critical sections to include not just invoking
4283 localtime/gmtime, but also accessing these functions' results
4284 including their tm_zone values if any, and any related TZ setting.
4285 (format_time_string): Last arg is now struct tm *, not struct tm **,
4286 so that the struct tm is saved in the critical section.
4287 All callers changed. Simplify allocation of initial buffer, partly
4288 motivated by the fact that memory allocation needs to be outside
4289 the critical section.
4291 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
4293 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
4294 with RESET_INTERVAL.
4296 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
4297 Remove duplicated buffer name initialization.
4299 2012-05-02 Jim Meyering <jim@meyering.net>
4301 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
4303 * xfns.c (x_window): Use xstrdup (Bug#11375).
4305 2012-05-02 Eli Zaretskii <eliz@gnu.org>
4307 * xdisp.c (pos_visible_p): If already at a newline from the
4308 display string before the 'while' loop, don't walk back the glyphs
4309 from it3.glyph_row. Solves assertion violation when the display
4310 string begins with a newline (egg.el). (Bug#11367)
4312 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
4314 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):

4319 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
4320 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
4321 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
4322 All were removed before 23.1.
4324 * dispnew.c: Remove HAVE_LIBNCURSES test;
4325 it is always true on relevant platforms.
4327 * Makefile.in (LD_SWITCH_X_SITE_RPATH):

4340 Do not avoid creating empty evaporating overlays (Bug#9642).
4341 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
4342 That is, do not delete an evaporating overlay if it becomes
4343 empty after its bounds are adjusted to fit within its buffer.
4344 This fix caused other problems, and I'm reverting it until we get
4345 to the bottom of them.
4347 2012-04-27 Chong Yidong <cyd@gnu.org>
4349 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
4351 2012-04-27 Eli Zaretskii <eliz@gnu.org>
4353 * xdisp.c (pos_visible_p): If the window start position is beyond
4354 ZV, start the display from buffer beginning. Prevents assertion
4355 violation in init_iterator when the minibuffer window is scrolled
4356 via the scroll bar.
4358 * window.c (window_scroll_pixel_based): Likewise.
4360 2012-04-27 Chong Yidong <cyd@gnu.org>
4362 * keymap.c (where_is_internal): Doc fix (Bug#10872).

4376 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
4377 display element, check also the underlying string or buffer
4378 character. (Bug#11341)
4380 * w32menu.c: Include w32heap.h.
4381 (add_menu_item): If the call to AppendMenuW (via
4382 unicode_append_menu) fails, disable Unicode menus only if we are
4383 running on Windows 9X/Me.
4385 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
4387 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
4388 (xgetint): Add missing shift for LSB tags.
4390 2012-04-24 Martin Rudalics <rudalics@gmx.at>
4392 * keyboard.c (read_char): Don't wipe echo area for select window
4393 events: These might get delayed via `mouse-autoselect-window'
4394 (Bug#11304).
4396 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
4398 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
4399 manipulation of :loaded-from data.
4401 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
4403 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
4404 now a cons (bug#11311).
4406 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
4408 Do not create empty overlays with the evaporate property (Bug#9642).
4409 * buffer.c (Fmove_overlay): Delete an evaporating overlay
4410 if it becomes empty after its bounds are adjusted to fit within
4411 its buffer. Without this fix, in a nonempty buffer (let ((o
4412 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
4413 yields an empty overlay that has the evaporate property, which is
4414 not supposed to happen.
4416 Fix minor GTK3 problems found by static checking.
4417 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
4418 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
4419 (struct _EmacsFixedClass, emacs_fixed_get_type):

4436 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
4437 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
4438 (__malloc_size_t, __malloc_ptrdiff_t):
4439 Remove. All uses removed, replaced by the definiens if needed,
4440 since we can assume C89 or better now.

4451 Define using prototypes, not old style.
4452 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):

4531 * sysdep.c [__FreeBSD__]: Minor cleanups.
4532 (list_system_processes, system_process_attributes) [__FreeBSD__]:
4533 Use Emacs indenting style more consistently. Avoid some casts.

4557 2012-04-20 Chong Yidong <cyd@gnu.org>
4559 * process.c (wait_reading_process_output): If EIO occurs on a pty,
4560 set the status to "failed" and ensure that sentinel is run.

4688 2012-04-11 Daniel Colascione <dancol@dancol.org>
4690 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
4691 against is gone. It's better to use vfork now so that when Cygwin
4692 gains a new, working vfork, we use it automatically (bug#10398).

4751 * xdisp.c (set_cursor_from_row): If the display string appears in
4752 the buffer at position that is closer to point than the position
4753 after the display string, display the cursor on the first glyph of
4754 the display string. Fixes cursor display when a 'display' text
4755 property immediately follows invisible text. (Bug#11094)
4757 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
4759 composite.c: use 'double' consistently
4760 * composite.c (get_composition_id): Use 'double' consistently
4761 instead of converting 'float' to 'double' and vice versa; this is
4762 easier to understand and avoids a GCC warning.
4764 2012-04-09 Glenn Morris <rgm@gnu.org>
4766 * Makefile.in: Generate leim-list with bootstrap-emacs, in
4767 preparation for dumping it with emacs. (Bug#4789)
4768 (leimdir): New variable.
4769 ($(leimdir)/leim-list.el): New rule.
4770 (emacs$(EXEEXT)): Depend on leim-list.el.
4772 * buffer.c (Qucs_set_table_for_input): Remove. (Bug#9821)
4773 (Fget_buffer_create): Don't call Qucs_set_table_for_input.

4783 * xml.c (init_libxml2_functions) [WINDOWSNT]:
4784 Remove unused local variable.
4786 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
4788 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
4789 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
4790 (mark_memory): Mark Lisp_Objects only if pointers might hide in
4791 objects, as mark_maybe_pointer will catch them otherwise.
4792 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
4793 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
4795 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
4797 Fix typo that broke non-Windows builds.
4798 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.
4800 2012-04-07 Eli Zaretskii <eliz@gnu.org>
4802 Support building on MS-Windows with libxml2.
4804 * makefile.w32-in (OBJ2): Add xml.$(O).
4805 (GLOBAL_SOURCES): Add xml.c.
4806 ($(BLD)/xml.$(O)): New dependency list.
4808 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
4809 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
4810 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
4811 [!WINDOWSNT]: New macros.
4812 (init_libxml2_functions, libxml2_loaded_p): New functions.
4813 (parse_region): Call fn_xmlCheckVersion instead of using the macro
4814 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
4815 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
4816 Calls xmlCleanupParser only if libxml2 was loaded (or statically
4817 linked in).
4818 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
4819 Call init_libxml2_functions before calling libxml2 functions.
4820 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
4822 * emacs.c: Don't include libxml/parser.h.
4823 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
4824 xmlCleanupParser directly.
4826 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
4828 2012-04-07 Eli Zaretskii <eliz@gnu.org>
4830 * indent.c (Fvertical_motion): If there is a display string at
4831 point, use it.vpos to compute how many lines to backtrack after
4832 move_it_to point. (Bug#11133)
4834 2012-04-06 Eli Zaretskii <eliz@gnu.org>
4836 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
4837 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
4838 about subtle differences between FETCH_CHAR* and STRING_CHAR*
4839 macros related to unification of CJK characters. For the details,
4840 see the discussion following the message here:
4841 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
4843 2012-04-04 Chong Yidong <cyd@gnu.org>
4845 * keyboard.c (Vdelayed_warnings_list): Doc fix.
4847 2012-04-01 Eli Zaretskii <eliz@gnu.org>
4849 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
4850 instead of alloca. (Bug#11138)
4852 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
4854 * w32menu.c (is_simple_dialog): Properly check lisp types.
4855 (Bug#11141)
4857 2012-03-31 Eli Zaretskii <eliz@gnu.org>
4859 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
4860 position we get to after a call to move_it_to fails the
4861 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
4862 only if we wind up in a string from display property. (Bug#11063)
4864 * window.c (Fdelete_other_windows_internal): Invalidate the row
4865 and column information about mouse highlight, so that redisplay
4866 restores it after reallocating the glyph matrices. (Bug#7464)
4868 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
4869 string comes from a `display' text property, use the buffer
4870 position of that property as if we actually saw that position in
4871 the row's glyphs.
4872 (move_it_by_lines): Remove the assertion that
4873 "it->current_x == 0 && it->hpos == 0" which can be legitimately
4874 violated when there's a before-string at the beginning of a line.
4875 (Bug#11063)
4877 2012-03-30 Eli Zaretskii <eliz@gnu.org>
4879 * xdisp.c (append_space_for_newline): If the default face was
4880 remapped, use the remapped face for the appended newline.
4881 (extend_face_to_end_of_line): Use the remapped default face for
4882 extending the face to the end of the line.
4883 (display_line): Call extend_face_to_end_of_line when the default
4884 face was remapped. (Bug#11068)
4886 2012-03-29 Eli Zaretskii <eliz@gnu.org>
4888 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
4890 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
4892 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
4894 2012-03-27 Glenn Morris <rgm@gnu.org>
4896 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
4897 Doc fixes.
4899 2012-03-26 Kenichi Handa <handa@m17n.org>
4901 * dispextern.h (struct glyph): Fix previous change. Change the
4902 bit length of glyphless.ch to 25 (Bug#11082).
4904 2012-03-26 Chong Yidong <cyd@gnu.org>
4906 * keyboard.c (Vselection_inhibit_update_commands): New variable.
4907 (command_loop_1): Use it; inhibit selection update for
4908 handle-select-window too (Bug#8996).
4910 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
4912 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
4914 2012-03-25 Kenichi Handa <handa@m17n.org>
4916 * dispextern.h (struct glyph): Change the bit length of
4917 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
4919 2012-03-24 Eli Zaretskii <eliz@gnu.org>
4921 * s/ms-w32.h (tzname): Include time.h before redirecting to
4922 _tzname. Fixes the MSVC build. (Bug#9960)
4924 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
4926 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
4927 characters.
4929 * xterm.c (XTread_socket): Only modify handling_signal if
4930 !SYNC_INPUT. (Bug#11080)
4932 2012-03-23 Eli Zaretskii <eliz@gnu.org>
4934 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
4935 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
4936 when fetching a multibyte character consumes more bytes than
4937 CHAR_BYTES returns, due to unification of CJK characters in
4938 string_char. (Bug#11073)
4940 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
4942 * process.c (wait_reading_process_output): Handle pty disconnect
4943 by refraining from sending oneself a SIGCHLD (bug#10933).
4945 2012-03-22 Chong Yidong <cyd@gnu.org>
4947 * dispextern.h (struct it): New member string_from_prefix_prop_p.
4949 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
4950 Mark string as coming from a prefix property.
4951 (handle_face_prop): Use default face for prefix strings (Bug#4281).
4952 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
4954 2012-03-21 Chong Yidong <cyd@gnu.org>
4956 * xfaces.c (Vface_remapping_alist): Doc fix.
4958 2012-03-20 Eli Zaretskii <eliz@gnu.org>
4960 * w32proc.c (Fw32_set_console_codepage)
4961 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
4962 Doc fixes.
4964 2012-03-20 Chong Yidong <cyd@gnu.org>
4966 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
4967 to reflect default non-nil value of redisplay-dont-pause.
4969 2012-03-19 Kenichi Handa <handa@m17n.org>
4971 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
4972 it fit in a valid range (Bug#11003).
4974 2012-03-18 Eli Zaretskii <eliz@gnu.org>
4976 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
4977 that is not from display property, accept the row as a "cursor
4978 row" if one of the string's character has a non-nil `cursor'
4979 property. Fixes cursor positioning when there are newlines in
4980 overlay strings, e.g. in icomplete.el. (Bug#11035)
4982 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
4984 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
4986 2012-03-12 Chong Yidong <cyd@gnu.org>
4988 * eval.c (inhibit_lisp_code): Rename from
4989 inhibit_window_configuration_change_hook; move from window.c.
4991 * xfns.c (unwind_create_frame_1, Fx_create_frame):
4992 * window.c (run_window_configuration_change_hook)
4993 (syms_of_window): Callers changed.
4995 2012-03-11 Chong Yidong <cyd@gnu.org>
4997 * keymap.c (Fkey_description): Doc fix (Bug#9700).

5003 * frame.c (other_visible_frames): Don't assume the selected frame
5004 is visible (Bug#10955).
5006 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
5008 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
5010 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
5012 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
5013 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
5014 zero (Bug#10954).
5016 2012-03-03 Glenn Morris <rgm@gnu.org>
5018 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
5020 2012-03-02 Eli Zaretskii <eliz@gnu.org>
5022 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
5023 position past the first glyph_row that ends at ZV. (Bug#10902)
5024 (redisplay_window, next_element_from_string): Fix typos in
5025 comments.
5026 (redisplay_window): Pass to move_it_vertically the margin in
5027 pixels, not in screen lines.
5029 2012-03-02 Glenn Morris <rgm@gnu.org>
5031 * buffer.c (buffer-list-update-hook): Doc fix.
5033 2012-02-29 Eli Zaretskii <eliz@gnu.org>
5035 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
5036 push_it before setting up the iterator for the first overlay
5037 string, even if we have an empty string loaded.
5038 (next_overlay_string): If there's an empty string on the iterator
5039 stack, pop the stack. (Bug#10903)
5041 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
5043 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
5044 Suggested by Stefan Monnier in
5045 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
5046 * alloc.c (widen_to_Lisp_Object): New static function.
5047 (mark_memory): Also mark Lisp_Objects by fetching pointer words
5048 and widening them to Lisp_Objects. This would work even if
5049 USE_LSB_TAG is defined and wide integers are used, which might
5050 happen in a future version of Emacs.
5052 2012-02-25 Chong Yidong <cyd@gnu.org>
5054 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
5055 Doc fix.
5057 * xselect.c (Fx_selection_exists_p): Doc fix.
5058 (x_clipboard_manager_save_all): Print an informative message
5059 before saving to clipboard manager.
5061 2012-02-24 Chong Yidong <cyd@gnu.org>
5063 * keyboard.c (process_special_events): Handle all X selection
5064 requests in kbd_buffer, not just the next one (Bug#8869).
5066 2012-02-23 Chong Yidong <cyd@gnu.org>
5068 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
5069 call when setting menu-bar-lines and tool-bar-lines parameters.
5070 (unwind_create_frame_1): New helper function.
5072 * window.c (inhibit_window_configuration_change_hook): New var.
5073 (run_window_configuration_change_hook): Obey it.
5074 (syms_of_window): Initialize it.
5076 2012-02-22 Chong Yidong <cyd@gnu.org>
5078 * xterm.c (x_draw_image_relief): Add missing type check for
5079 Vtool_bar_button_margin (Bug#10743).
5081 2012-02-21 Chong Yidong <cyd@gnu.org>
5083 * fileio.c (Vfile_name_handler_alist): Doc fix.
5085 * buffer.c (Fget_file_buffer): Protect against invalid file
5086 handler return value.
5088 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
5090 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
5091 when computing $valmask.
5093 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
5094 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
5095 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
5096 It's useless in that case, and it can cause problems on hosts
5097 that allocate halves of EMACS_INT values separately.
5098 Reported by Dan Horák. Diagnosed by Andreas Schwab in
5099 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
5100 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
5101 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
5102 it avoids undefined behavior on hosts where shifting right by more
5103 than the word width has undefined behavior.
5105 2012-02-19 Chong Yidong <cyd@gnu.org>
5107 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
5108 (Funhandled_file_name_directory, Ffile_name_as_directory)
5109 (Fdirectory_file_name, Fexpand_file_name)
5110 (Fsubstitute_in_file_name): Protect against invalid file handler
5111 return values (Bug#10845).
5113 2012-02-18 Eli Zaretskii <eliz@gnu.org>
5115 * .gdbinit (pitx): Fix incorrect references to fields of the
5116 iterator stack.
5118 2012-02-17 Chong Yidong <cyd@gnu.org>
5120 * syntax.c (Fscan_lists): Doc fix (Bug#10833).
5122 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
5124 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
5125 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
5127 2012-02-15 Chong Yidong <cyd@gnu.org>
5129 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
5130 marked as special. Also, starting docstrings with * is obsolete.
5132 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
5134 * gnutls.c (emacs_gnutls_write): Fix last change.
5136 2012-02-13 Lars Ingebrigtsen <larsi@gnus.org>
5138 * gnutls.c (emacs_gnutls_write): Set errno appropriately for
5139 send_process.
5141 2012-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
5143 * keymap.c (Fsingle_key_description): Handle char ranges.
5145 2012-02-12 Chong Yidong <cyd@gnu.org>
5147 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
5148 as that creates a dangerous corner case.
5150 * window.c (Fdelete_window_internal): Invalidate the mouse
5151 highlight (Bug#9904).
5153 2012-02-12 Glenn Morris <rgm@gnu.org>
5155 * xselect.c (Fx_own_selection_internal)
5156 (Fx_get_selection_internal, Fx_disown_selection_internal)
5157 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
5158 * nsselect.m (Fx_own_selection_internal)
5159 (Fx_disown_selection_internal, Fx_selection_exists_p)
5160 (Fx_selection_owner_p, Fx_get_selection_internal):
5161 Sync docs and argument specs with the xselect.c versions.
5163 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
5165 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
5167 2012-02-11 Eli Zaretskii <eliz@gnu.org>
5169 * w32select.c (Fx_selection_exists_p): Sync doc string and
5170 argument list with xselect.c. (Bug#10783)
5172 * w16select.c (Fx_selection_exists_p): Sync doc string and
5173 argument list with xselect.c. (Bug#10783)

5183 2012-02-07 Chong Yidong <cyd@gnu.org>
5185 * buffer.c (Fbuffer_local_variables)
5186 (buffer_lisp_local_variables): Handle unbound vars correctly;
5187 don't let Qunbound leak into Lisp.
5189 2012-02-07 Glenn Morris <rgm@gnu.org>
5191 * image.c (Fimagemagick_types): Doc fix.
5193 * image.c (imagemagick-render-type): Change it from a lisp object
5194 to an integer. Move the doc here from the lisp manual.
5195 Treat all values not equal to 0 the same.
5197 2012-02-06 Chong Yidong <cyd@gnu.org>
5199 * doc.c (store_function_docstring): Avoid applying docstring of
5200 alias to base function (Bug#2603).
5202 2012-02-04 Andreas Schwab <schwab@linux-m68k.org>
5204 * .gdbinit (pp1, pv1): Remove redundant defines.
5205 (pr): Use pp.
5207 2012-02-04 Chong Yidong <cyd@gnu.org>
5209 * nsterm.m: Declare a global (Bug#10694).
5211 2012-02-04 Eli Zaretskii <eliz@gnu.org>
5213 * w32.c (get_emacs_configuration_options):
5214 Include --enable-checking, if specified, in the return value.
5216 2012-02-04 Martin Rudalics <rudalics@gmx.at>
5218 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
5219 after rounding frame sizes. (Bug#9723)
5221 2012-02-04 Eli Zaretskii <eliz@gnu.org>
5223 * keyboard.c (adjust_point_for_property): Don't position point
5224 before BEGV. (Bug#10696)
5226 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
5228 Handle overflow when computing char display width (Bug#9496).
5229 * character.c (char_width): Return EMACS_INT, not int.
5230 (char_width, c_string_width): Check for overflow when
5231 computing the width; this is possible now that individual
5232 characters can have unbounded width. Problem introduced
5233 by merge from Emacs 23 on 2012-01-19.
5235 2012-02-02 Michael Albinus <michael.albinus@gmx.de>
5237 * dbusbind.c (Fdbus_register_method): Mention the return value
5238 :ignore in the docstring.

5757 unnecessary graphics copy operations.
5759 2011-11-27 Eli Zaretskii <eliz@gnu.org>
5761 * s/ms-w32.h (utimbuf) [_MSC_VER]: Don't define.
5762 (snprintf) [_MSC_VER]: Redirect to _snprintf.
5763 (strtoll) [_MSC_VER]: Redirect to _strtoi64.
5764 (malloc, free, realloc, calloc): Redirect to e_* only when
5765 compiling Emacs.
5767 * lisp.h (GCTYPEBITS): Move before first use.
5768 (ALIGN_GCTYPEBITS) [_MSC_VER]: Define.
5769 (DECL_ALIGN) [_MSC_VER]: Use it, as MSVC doesn't like bit ops in

5783 * fileio.c (Finsert_file_contents): Undo previous change; see
5784 <http://lists.gnu.org/archive/html/emacs-diffs/2011-11/msg00265.html>.

5798 after recentering, and scroll-conservatively is set to a large
5799 number, scroll window by a few more lines to make the cursor fully
5800 visible and out of scroll-margin. (Bug#10105)
5801 (start_display): Don't move to the next line if the display should
5802 start at a newline that is part of a display vector or an overlay
5803 string. (Bug#10119)

5883 Otherwise, valgrind does not work on some platforms.
5884 Problem reported by Andreas Schwab in
5885 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
5886 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
5887 is set, removing the need for VIRT_ADDRESS_VARIES.
5888 (PURE_P): Use a more-efficient implementation that needs just one
5889 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
5890 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
5891 to 4 (xorl, subq, cmpq, setbe).
5892 * alloc.c (pure): Always extern now, since that's the
5893 VIRT_ADDR_VARIES behavior.
5894 (PURE_POINTER_P): Use a single comparison, not two, for
5895 consistency with the new puresize.h.
5896 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
5897 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

5903 (erase_phys_cursor, update_window_cursor, show_mouse_face)
5904 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
5905 behave as if the cursor position were at the window margin.
5907 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
5908 and the cursor position is out of bounds, behave as if the cursor
5909 position were at the window margin. (Bug#10075)
5911 2011-11-18 Chong Yidong <cyd@gnu.org>
5913 * window.c (Fwindow_combination_limit): Make first argument
5914 non-optional, since it is meaningless for live windows like the
5915 selected window.

5929 hash values of the two rows.
5930 (copy_row_except_pointers): Preserve the used[] arrays and the
5931 hash values of the two rows. (Bug#10035)
5932 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
5934 * xdisp.c (row_hash): New function, body extracted from
5935 compute_line_metrics.
5936 (compute_line_metrics): Call row_hash, instead of computing the
5937 hash code inline.
5939 * dispnew.c (verify_row_hash): Call row_hash for computing the
5940 hash code of a row, instead of duplicating code from xdisp.c.
5942 * dispextern.h (row_hash): Add prototype.
5944 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>

5969 (Fset_window_nest): Rename to Fset_window_combination_limit.
5970 (Vwindow_nest): Rename to Vwindow_combination_limit.
5971 (recombine_windows, make_parent_window, make_window)
5972 (Fsplit_window_internal, saved_window)
5973 (Fset_window_configuration, save_window_save): Rename all
5974 occurrences of window_nest to window_combination_limit.
5976 2011-11-15 Juanma Barranquero <lekktu@gmail.com>
5978 * image.c (imagemagick_load_image): Fix typo.
5980 2011-11-14 Eli Zaretskii <eliz@gnu.org>
5982 * xdisp.c (display_line): Move the call to
5983 highlight_trailing_whitespace before the call to
5984 compute_line_metrics, since the latter needs to see the final
5985 faces of all the glyphs to compute ROW's hash value.
5986 Fixes assertion violations in row_equal_p. (Bug#10035)
5988 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
5990 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
5991 just return (bug#10044).

5995 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
5996 with user-defined heap size. Bump the default size of the temacs
5997 heap to 27MB, to avoid memory warning when running temacs.
5998 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
6000 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
6001 current_matrix and desired_matrix. (Bug#9990)
6002 (verify_row_hash) [XASSERTS]: New function.
6003 (adjust_glyph_matrix, row_equal_p): Use it in xassert to verify
6004 that the hash value of glyph rows is correct.

6047 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
6049 Avoid some portability problems by eschewing 'extern inline' functions.
6050 The trivial performance wins aren't worth the portability hassles; see
6051 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
6052 et seq.
6053 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
6054 (window_box_width, window_box_left, window_box_left_offset)
6055 (window_box_right, window_box_right_offset): Undo previous change,
6056 by removing the "extern"s.
6057 * intervals.c (adjust_intervals_for_insertion)
6058 (adjust_intervals_for_deletion): Undo previous change,
6059 making these static again.
6060 (offset_intervals, temp_set_point_both, temp_set_point)
6061 (copy_intervals_to_string): No longer inline.
6062 * xdisp.c (window_text_bottom_y, window_box_width)

6119 * xmenu.c (cleanup_widget_value_tree): New function.
6120 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of

6127 (window_box_width, window_box_left, window_box_left_offset)
6128 (window_box_right, window_box_right_offset): Declare extern.
6129 Otherwise, these inline functions do not conform to C99 and
6130 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
6131 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
6132 * intervals.c (adjust_intervals_for_insertion)
6133 (adjust_intervals_for_deletion): Now extern, because otherwise the
6134 extern inline functions 'offset_intervals' couldn't refer to it.
6135 (static_offset_intervals): Remove.
6136 (offset_intervals): Rewrite using the old contents of
6137 static_offset_intervals. The old version didn't conform to C99
6138 because an extern inline function contained a reference to an
6139 identifier with static linkage.
6141 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
6143 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

6160 (Fwindow_margins, Fwindow_fringes, Fwindow_scroll_bars)
6161 (Fwindow_vscroll): Doc fix.
6162 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
6163 argument, since it makes no sense to pass a live window and for

6243 2011-11-04 Eli Zaretskii <eliz@gnu.org>
6245 * xdisp.c (note_mouse_highlight): If either of
6246 previous/next-single-property-change returns nil, treat that as
6247 the beginning or the end of the buffer. (Bug#9955)
6249 2011-11-04 Jan Djärv <jan.h.d@swipnet.se>

6275 Rename cover_string to disp_string.
6277 2011-11-01 Martin Rudalics <rudalics@gmx.at>
6279 * window.c (temp_output_buffer_show): Don't use
6280 Vtemp_buffer_show_specifiers.
6281 (Vtemp_buffer_show_specifiers): Remove unused variable.
6283 2011-10-30 Eli Zaretskii <eliz@gnu.org>
6285 * xdisp.c (try_cursor_movement): Make sure ROW isn't decremented

6334 2011-10-29 Glenn Morris <rgm@gnu.org>
6336 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
6337 Not clear what it was for, and it causes various bugs. (Bug#9839)
6339 2011-10-28 Eli Zaretskii <eliz@gnu.org>
6341 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
6342 possible random value that matches one of those tested as
6343 condition to clear the mouse face.
6345 2011-10-28 Chong Yidong <cyd@gnu.org>
6347 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.

6361 2011-10-28 Eli Zaretskii <eliz@gnu.org>
6363 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
6364 <oslsachem@gmail.com> for helping to debug this.
6366 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)

6372 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
6373 New functions.
6374 (w32font_open_internal, compute_metrics):
6375 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
6376 instead of calling the "wide" APIs directly.
6378 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
6380 * w32.h (syms_of_w32font): Add prototype.
6382 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
6384 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
6385 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
6386 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
6387 (Fmove_to_window_line): Doc fix.
6389 2011-10-27 Chong Yidong <cyd@gnu.org>
6391 * process.c (make_process): Set gnutls_state to NULL.
6393 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
6394 non-NULL, regardless of GNUTLS_INITSTAGE.
6395 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
6396 an error. Set process slots as soon as we allocate them.

6419 extracted from Fw32_default_color_map.
6420 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
6422 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
6424 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
6426 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
6428 * keyboard.c (test_undefined): New function (bug#9751).
6429 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
6431 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
6433 * sysdep.c (init_sys_modes): Fix the check for the controlling
6434 terminal (Bug#6649).
6436 2011-10-20 Eli Zaretskii <eliz@gnu.org>
6438 * dispextern.h (struct bidi_it): New member next_en_type.
6440 * bidi.c (bidi_line_init): Initialize the next_en_type member.
6441 (bidi_resolve_explicit_1): When next_en_pos is valid for the
6442 current character, check also for next_en_type being WEAK_EN.
6443 (bidi_resolve_weak): Don't enter the expensive loop if the current
6444 position is before next_en_pos. Record the bidi type of the first
6445 non-ET, non-BN character we find, in addition to its position.
6446 (bidi_level_of_next_char): Invalidate next_en_type when
6447 next_en_pos is over-stepped.
6449 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
6451 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
6452 * editfns.c: Rewrite current-time-zone so that it invokes
6453 the equivalent of (format-time-string "%Z") to get the time zone name.
6454 This fixes a bug when the time zone name contains characters that
6455 need converting from the system time locale to Emacs internal format.
6456 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
6457 that patch fixed format-time-string to do the conversion, but
6458 I forgot to fix current-time-zone.
6459 (format_time_string): New function, containing most of
6460 what Fformat_time_string used to contain.
6461 (Fformat_time_string): Rewrite in terms of format_time_string.
6462 This doesn't change this function's behavior.
6463 (current-time-zone): Rewrite to use format_time_string.
6464 This fixes the bug reported by Michael Schierl in
6465 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
6466 Jason Rumney's 2007-06-07 change worked around this bug, but
6467 didn't fix it.
6468 * systime.h (tzname, timezone): Remove no-longer-used declarations.
6470 2011-10-19 Eli Zaretskii <eliz@gnu.org>
6472 * xdisp.c (start_display): If the character at POS is displayed
6473 via a display vector, reset IT->current.dpvec_index to zero.
6474 (try_window_reusing_current_matrix): If a line ends in a display
6475 vector or the next line starts in a display vector, continue
6476 redrawing the window even though the character position of
6477 start_row was reached.
6478 (Bug#9771, part 2)
6480 2011-10-18 Chong Yidong <cyd@gnu.org>
6482 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
6483 with nobreak-char-display too.
6485 2011-10-18 Eli Zaretskii <eliz@gnu.org>
6487 Fix part 3 of bug#9771.
6488 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
6489 (bidi_resolve_neutral): Don't enter the expensive loop looking for
6490 non-neutral characters if the current character is a paragraph
6491 separator (a.k.a. Newline). This avoids running the same
6492 expensive loop twice, once when we consume the preceding newline
6493 and the other time when the line actually needs to be displayed.
6494 Avoid the loop when we see neutrals on the base embedding level
6495 following a character whose directionality is the same as the
6496 paragraph's. This avoids running the expensive loop when a line
6497 ends in a long sequence of neutrals, like control characters.
6498 Add assertion against STRONG_AL type. Slightly rearrange code
6499 that determines the type of a neutral given the first non-neutral
6500 that follows it.
6501 (bidi_level_of_next_char): Set next_en_pos to zero when
6502 invalidating its info.
6504 2011-10-17 Eli Zaretskii <eliz@gnu.org>
6506 * xdisp.c (push_display_prop): Determine whether to record string
6507 or buffer position by IT->string, not by IT->method. Allow
6508 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
6509 (move_it_vertically_backward): Don't look for character position
6510 immediately after the newline when in a continuation line.
6511 (Bug#9771, part 1)
6513 2011-10-15 Martin Rudalics <rudalics@gmx.at>
6515 * window.c (coordinates_in_window): Rewrite and delabelize
6516 vertical border check. (Bug#5357) (Bug#9618)
6518 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
6520 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
6521 errors in XSetWindowBorder (bug#9310).
6523 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
6525 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
6526 avoid crash when xmalloc overrun checking is enabled.
6528 2011-10-13 Eli Zaretskii <eliz@gnu.org>
6530 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
6531 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
6532 cursor motion with <left> and <right> arrow keys.
6534 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
6535 some callers set that themselves.
6537 2011-10-12 Eli Zaretskii <eliz@gnu.org>
6539 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
6540 display string and the previous row comes from the same string and
6541 is empty. (Bug#9739) (Bug#9738)
6543 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
6545 * doc.c (get_doc_string): Encode file name (bug#9735).
6547 2011-10-12 Eli Zaretskii <eliz@gnu.org>
6549 * bidi.c (bidi_level_of_next_char):
6550 * xdisp.c (get_visually_first_element): Remove old incorrect
6551 comments regarding the Unicode Line Separator character.
6553 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
6555 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
6557 * alloc.c (Fgc_status): Do not access beyond zombies array
6558 boundary if nzombies > MAX_ZOMBIES.
6559 * alloc.c (dump_zombies): Add missing format specifier.
6561 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
6563 * xdisp.c (set_cursor_from_row): Simplify conditionals,
6564 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
6566 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
6567 Some packages use them to denote characters with modifiers.
6569 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
6571 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
6572 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
6573 matching a pp-number. Rename parameter var to var1.
6575 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
6577 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
6579 2011-10-08 Glenn Morris <rgm@gnu.org>
6581 * callint.c (Fcall_interactively): Give a more explicit error for the
6582 'c' case with a non-character input. (Bug#8479)
6584 2011-10-08 Eli Zaretskii <eliz@gnu.org>
6586 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
6587 lines.
6588 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
6589 lines that are hscrolled on the left.
6591 * dispnew.c (buffer_posn_from_coords): Account for a possible
6592 presence of header-line. (Bug#4426)
6594 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
6596 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
6597 Don't advertise functionality which we discourage or doesn't work.
6599 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
6601 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
6602 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
6603 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
6604 this makes Emacs dump core during garbage collection on rare
6605 occasions. sizeof is obviously inferior to offsetof here, so
6606 stick with offsetof.
6607 (GC_POINTER_ALIGNMENT): New macro.
6608 (mark_memory): Omit 3rd (offset) arg; caller changed.
6609 Don't assume EMACS_INT alignment is the same as pointer alignment.
6611 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
6613 * keyboard.c (read_key_sequence_remapped): New var.
6614 (read_key_sequence): Compute remapping in the right buffer.
6615 (command_loop_1): Use read_key_sequence's remapping directly.
6617 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
6619 * dired.c (file_name_completion): Don't expand file name.
6620 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
6621 before checking file name handler.
6623 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
6624 they've been requested explicitly (bug#9591).
6626 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
6628 * keymap.c (Fsingle_key_description): Use make_specified_string
6629 instead of build_string to build string from push_key_description.
6630 (Bug#5193)
6632 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
6634 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
6635 This fixes a Y2038 bug on 64-bit hosts.
6636 * buffer.c (reset_buffer):
6637 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
6638 (Fclear_buffer_auto_save_failure):
6639 Use 0, not -1, to represent an unset failure time, since time_t
6640 might not be signed.
6642 Remove dependency on glibc malloc internals.
6643 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6644 Move back here from lisp.h, but with their new implementations.
6645 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
6646 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
6647 * charset.c (charset_table_init): New static var.
6648 (syms_of_charset): Use it instead of xmalloc. This removes a
6649 dependency on glibc malloc internals. See Eli Zaretskii's comment in
6650 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
6651 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6652 Move back to alloc.c.
6653 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
6654 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
6656 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
6658 * nsterm.m (windowDidResize): Call x_set_window_size only when
6659 ns_in_resize is true. Otherwise set pixelwidth/height and
6660 call change_frame_size (Bug#9628).
6662 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
6664 Port --enable-checking=all to Fedora 14 x86-64.
6665 * charset.c (syms_of_charset): Also account for glibc malloc's
6666 internal overhead when calculating the initial malloc maximum.
6668 Port --enable-checking=all to Fedora 14 x86.
6669 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6670 Move to lisp.h.
6671 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
6672 (overrun_check_realloc, overrun_check_free):
6673 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
6674 That way, xmalloc returns a properly-aligned pointer even if
6675 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
6676 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
6677 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
6678 into account when calculating the initial malloc maximum.
6679 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6680 Move here from alloc.c, so that charset.c can use it too.
6681 Properly align; the old code wasn't right for common 32-bit hosts
6682 when configured with --enable-checking=all.
6683 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
6684 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
6686 2011-09-29 Eli Zaretskii <eliz@gnu.org>
6688 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
6689 use EDOM.
6691 2011-09-28 Eli Zaretskii <eliz@gnu.org>
6693 * xdisp.c (compute_display_string_end): If there's no display
6694 string at CHARPOS, return -1.
6696 * bidi.c (bidi_fetch_char): When compute_display_string_end
6697 returns a negative value, treat the character as a normal
6698 character not covered by a display string. (Bug#9624)
6700 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
6702 * lread.c (Fread_from_string): Fix typo in docstring.
6704 2011-09-27 Eli Zaretskii <eliz@gnu.org>
6706 * xdisp.c (handle_invisible_prop): If invisible text ends on a
6707 newline, reseat the iterator instead of bidi-iterating there one
6708 character at a time. (Bug#9610)
6709 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
6710 TO_CHARPOS if the bidi iterator is at base embedding level.
6712 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
6714 * lread.c (readevalloop): Use correct code for NBSP.
6715 (read1): Likewise. (Bug#9608)
6717 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
6719 * dbusbind.c (Fdbus_register_signal): When service is not
6720 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
6722 2011-09-25 Glenn Morris <rgm@gnu.org>
6724 * buffer.c (truncate-lines): Doc fix.
6726 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
6728 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
6729 (Fset_window_next_buffers): Doc fix.
6731 2011-09-24 Glenn Morris <rgm@gnu.org>
6733 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
6735 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
6737 Fix minor problems found by static checking.
6738 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
6739 * indent.c (Fvertical_motion): Fix == vs = typo.
6741 2011-09-24 Eli Zaretskii <eliz@gnu.org>
6743 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
6744 Default value is now t. Doc fix.
6746 * indent.c (Fvertical_motion): Compute and apply the overshoot
6747 logic when moving up, not only when moving down. Fix the
6748 confusing name and values of the it_overshoot_expected variable;
6749 logic changes accordingly. (Bug#9254) (Bug#9549)
6751 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
6752 CHARPOS is covered by a display string which includes newlines.
6753 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
6754 is covered by a display string with embedded newlines.
6756 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
6758 * dbusbind.c (Fdbus_register_signal): Add match rule to
6759 Vdbus_registered_objects_table. (Bug#9581)
6760 (Fdbus_register_method, Vdbus_registered_objects_table):
6761 Fix docstring.
6763 2011-09-24 Jim Meyering <meyering@redhat.com>
6765 do not ignore write error for any output size
6766 The previous change was incomplete.
6767 While it makes emacs --batch detect the vast majority of stdout
6768 write failures, errors were still ignored whenever the output size is
6769 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
6770 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
6771 && echo FAIL: ignored write error
6772 FAIL: ignored write error
6773 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
6774 && echo FAIL: ignored write error
6775 FAIL: ignored write error
6776 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
6778 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
6780 * emacs.c (Fkill_emacs): In noninteractive mode exit
6781 non-successfully if a write error occurred on stdout. (Bug#9574)
6783 2011-09-21 Eli Zaretskii <eliz@gnu.org>
6785 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
6786 the xassert test.
6788 * dispextern.h (struct it): Update the comment documenting what
6789 can it->OBJECT be.
6791 2011-09-20 Eli Zaretskii <eliz@gnu.org>
6793 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
6794 a display string, extend search for cursor position to end of row.
6795 (find_row_edges): If the row ends in a newline from a display
6796 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
6797 Handle the case of a display string with multiple newlines.
6798 (Fcurrent_bidi_paragraph_direction): Fix search for previous
6799 non-empty line. Fixes confusing cursor motion with arrow keys at
6800 the beginning of a line that starts with whitespace.
6802 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
6804 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
6805 (bug#9493).
6807 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
6809 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
6810 boolean (Bug#9154).
6812 2011-09-18 Eli Zaretskii <eliz@gnu.org>
6814 * xdisp.c (display_line): Record maximum and minimum buffer
6815 positions even if no glyphs were produced (e.g., by a zero-width
6816 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
6817 buffer positions that will be removed from the glyph row because
6818 they don't fit.
6819 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
6820 column is beyond frame width: don't subtract 1 "pixel" when
6821 computing width of the stretch.
6822 (reseat_at_next_visible_line_start): Undo the change made on
6823 2011-09-17 that saved paragraph information and restored it after
6824 the call to `reseat'. (Bug#9545)
6826 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6828 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
6829 and turn window cursor on if cleared (Bug#9415).
6831 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
6833 * search.c (boyer_moore): Take unibyte characters from pattern
6834 literally. (Bug#9458)
6836 2011-09-18 Eli Zaretskii <eliz@gnu.org>
6838 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
6840 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
6842 Fix minor problem found by static checking.
6843 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
6844 initialized, to pacify gcc -Wuninitialized.
6846 * fileio.c: Report proper errno when syscall falls.
6847 (Finsert_file_contents): Save and restore errno,
6848 so that report_file_error outputs the correct diagnostic.
6849 (Fwrite_region) [CLASH_DETECTION]: Likewise.
6851 2011-09-18 Eli Zaretskii <eliz@gnu.org>
6853 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
6855 2011-09-17 Eli Zaretskii <eliz@gnu.org>
6857 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
6858 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
6860 2011-09-17 Eli Zaretskii <eliz@gnu.org>
6862 * xdisp.c (reseat_at_next_visible_line_start): Keep information
6863 about the current paragraph and restore it after the call to reseat.
6865 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
6866 (bidi_find_paragraph_start): Search back for paragraph beginning
6867 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
6868 (bidi_move_to_visually_next): Only trigger paragraph-related
6869 computations when the last character is a newline or at EOB, not
6870 just any NEUTRAL_B. (Bug#9470)
6872 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
6873 truncated lines if point is covered by a display string. (Bug#9524)
6875 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
6877 * xselect.c: Relax test for outgoing X longs (Bug#9498).
6878 (cons_to_x_long): New function.
6879 (lisp_data_to_selection_data): Use it. Correct the test for
6880 short-versus-long data; it was negated. Break out of vector
6881 loop, for efficiency, when a long datum is discovered.
6883 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
6885 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
6887 2011-09-16 Eli Zaretskii <eliz@gnu.org>
6889 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
6890 GCC PR/17406) by declaring this function with external scope.
6892 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
6894 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
6895 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
6897 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
6899 * editfns.c (Fformat): Correctly handle text properties on "%%".
6901 2011-09-15 Eli Zaretskii <eliz@gnu.org>
6903 * xterm.c (x_draw_composite_glyph_string_foreground):
6904 * w32term.c (x_draw_composite_glyph_string_foreground):
6905 * term.c (encode_terminal_code):
6906 * composite.c (composition_update_it, get_composition_id):
6907 * xdisp.c (get_next_display_element)
6908 (fill_composite_glyph_string): Add comments about special meaning
6909 of TAB characters in a composition.
6911 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
6913 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
6914 This occurs when processing a multibyte format.
6915 Problem reported by Wolfgang Jenker.
6917 2011-09-15 Johan Bockgård <bojohan@gnu.org>
6919 * xdisp.c (try_cursor_movement): Only check for exact match if
6920 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
6922 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
6924 Remove unused external symbols.
6925 * dispextern.h (calc_pixel_width_or_height): Remove decl.
6926 * xdisp.c (calc_pixel_width_or_height): Now static.
6927 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
6928 * indent.c (check_display_width):
6929 * w32term.c: Fix comment to match code.
6930 * xterm.c, xterm.h (x_catching_errors): Remove.
6932 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
6934 * xselect.c: Use signed conversions more consistently (Bug#9498).
6935 (selection_data_to_lisp_data): Assume incoming selection data are
6936 signed integers, not unsigned. This is to be consistent with
6937 outgoing selection data, which was modified to use signed integers
6938 in as part of the fix to Bug#9196 in response to Jan D.'s comment
6939 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
6940 expects long, not unsigned long.
6942 2011-09-14 Eli Zaretskii <eliz@gnu.org>
6944 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
6945 computation of loop end. Reported by Johan Bockgård
6946 <bojohan@gnu.org>.
6948 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
6950 * frame.c (Fother_visible_frames_p): Function deleted.
6952 2011-09-12 Eli Zaretskii <eliz@gnu.org>
6954 * indent.c (compute_motion): Process display vector front to back
6955 rather than the other way around. (Bug#2496)
6957 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
6959 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
6961 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
6963 * minibuf.c (Fread_from_minibuffer): Doc fix.
6965 2011-09-11 Eli Zaretskii <eliz@gnu.org>
6967 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
6968 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
6970 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
6972 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
6973 value for non-existent files.
6975 2011-09-11 Eli Zaretskii <eliz@gnu.org>
6977 * fileio.c (Finsert_file_contents): If the file cannot be opened,
6978 set its "size" to -1. This will set the modtime_size field of
6979 the corresponding buffer to -1, which is what
6980 verify-visited-file-modtime expects for files that do not exist.
6981 (Bug#9139)
6983 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
6985 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
6986 here ...
6987 * lisp.h: ... from here. push_key_description is no longer
6988 defined in keyboard.c, so its declaration should not be in
6989 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
6990 logically belongs with push_key_description.
6992 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
6994 * buffer.h: Include <sys/types.h> instead of <time.h>.
6995 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
6996 Problem reported by Herbert J. Skuhra.
6998 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
7000 * xml.c (parse_region): Make the parsing work for
7001 non-comment-starting XML files again (bug#9144).
7003 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
7005 * image.c (gif_load): Fix calculation of bottom and right corner.
7006 (Bug#9468)
7008 2011-09-10 Eli Zaretskii <eliz@gnu.org>
7010 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
7011 redisplay in small windows.
7013 2011-09-09 Eli Zaretskii <eliz@gnu.org>
7015 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
7017 2011-09-08 Martin Rudalics <rudalics@gmx.at>
7019 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
7020 Operate on live windows only.
7022 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
7024 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
7026 2011-09-07 Eli Zaretskii <eliz@gnu.org>
7028 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
7029 only under bidi iteration.
7031 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
7033 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
7035 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7037 isnan: Fix porting problem to Solaris 10 with bundled gcc.
7038 Without this fix, the command to link temacs failed due to an
7039 undefined symbol __builtin_isnan. This is because
7040 /usr/include/iso/math_c99.h #defines isnan(x) to
7041 __builtin_isnan(x), but the bundled gcc, which identifies itself
7042 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
7043 a __builtin_isnan.
7044 * floatfns.c (isnan): #undef, and then #define to a clone of
7045 what's in data.c.
7046 (Fisnan): Always define, since it's always available now.
7047 (syms_of_floatfns): Always define isnan at the Lisp level.
7049 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7051 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
7053 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
7055 * fileio.c: Fix bugs with large file offsets (Bug#9428).
7056 The previous code assumed that file offsets (off_t values) fit in
7057 EMACS_INT variables, which is not true on typical 32-bit hosts.
7058 The code messed up by falsely reporting buffer overflow in cases
7059 such as (insert-file-contents "big" nil 1 2) into an empty buffer
7060 when "big" contains more than 2**29 bytes, even though this
7061 inserts just one byte and does not overflow the buffer.
7062 (Finsert_file_contents): Store file offsets as off_t
7063 values, not as EMACS_INT values. Check for overflow when
7064 converting between EMACS_INT and off_t. When checking for
7065 buffer overflow or for overlap, take the offsets into account.
7066 Don't use EMACS_INT for small values where int suffices.
7067 When checking for overlap, fix a typo: ZV was used where
7068 ZV_BYTE was intended.
7069 (Fwrite_region): Don't assume off_t fits into 'long'.
7070 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
7072 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
7074 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
7076 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7078 sprintf-related integer and memory overflow issues (Bug#9412).
7080 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
7081 (esprintf, exprintf, evxprintf): New functions.
7082 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
7083 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
7084 (modify_event_symbol): Do not assume that the length of
7085 name_alist_or_stem is safe to alloca and fits in int.
7086 (Fexecute_extended_command): Likewise for function name and binding.
7087 (Frecursion_depth): Wrap around reliably on integer overflow.
7088 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
7089 since some callers pass EMACS_INT values.
7090 (Fsingle_key_description): Don't crash if symbol name contains more
7091 than MAX_ALLOCA bytes.
7092 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
7093 (get_minibuffer): Arg is now EMACS_INT, not int.
7094 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
7095 (esprintf, exprintf, evxprintf): New decls.
7096 * window.h (command_loop_level, minibuf_level): Reflect API changes.
7098 * dbusbind.c (signature_cat): New function.
7099 (xd_signature, Fdbus_register_signal):
7100 Do not overrun buffer; instead, report string overflow.
7102 * dispnew.c (add_window_display_history): Don't overrun buffer.
7103 Truncate instead; this is OK since it's just a log.
7105 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
7106 even if the time zone offset is outlandishly large.
7107 Don't mishandle offset == INT_MIN.
7109 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
7110 when creating daemon; the previous buffer-overflow check was incorrect.
7112 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
7113 which has the guts of the old verror function.
7115 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
7116 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
7118 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
7119 (font_unparse_xlfd): Don't blindly alloca long strings.
7120 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
7121 fits in int, when using sprintf. Use single snprintf to count
7122 length of string rather than counting it via multiple sprintfs;
7123 that's simpler and more reliable.
7124 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
7125 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
7126 sprintf, in case result does not fit in int.
7128 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
7129 (fontset_from_font): Print it.
7131 * frame.c (tty_frame_count): Now printmax_t, not int.
7132 (make_terminal_frame, set_term_frame_name): Print it.
7133 (x_report_frame_params): In X, window IDs are unsigned long,
7134 not signed long, so print them as unsigned.
7135 (validate_x_resource_name): Check for implausibly long names,
7136 and don't assume name length fits in 'int'.
7137 (x_get_resource_string): Don't blindly alloca invocation name;
7138 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
7139 not fit in int.
7141 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
7142 (xg_check_special_colors, xg_set_geometry):
7143 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
7145 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
7146 Use esprintf, not sprintf, in case result does not fit in int.
7148 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7149 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
7150 it as a large positive number.
7151 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
7152 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7154 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
7155 in case result does not fit in int.
7157 * print.c (float_to_string): Detect width overflow more reliably.
7158 (print_object): Make sprintf buffer a bit bigger, to avoid potential
7159 buffer overrun. Don't assume list length fits in 'int'. Treat
7160 print length of 0 as 0, not as infinity; to be consistent with other
7161 uses of print length in this function. Don't overflow print length
7162 index. Don't assume hash table size fits in 'long', or that
7163 vectorlike size fits in 'unsigned long'.
7165 * process.c (make_process): Use printmax_t, not int, to format
7166 process-name gensyms.
7168 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
7170 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
7171 to avoid potential buffer overrun.
7173 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
7174 if X resource line is longer than 512 bytes.
7176 * xfns.c (x_window): Make sprintf buffer a bit bigger
7177 to avoid potential buffer overrun.
7179 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
7181 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
7183 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7185 Integer overflow fixes for scrolling, etc.
7186 Without these, Emacs silently mishandles large integers sometimes.
7187 For example, "C-u 4294967297 M-x recenter" was treated as if
7188 it were "C-u 1 M-x recenter" on a typical 64-bit host.
7190 * xdisp.c (try_window_id): Check Emacs fixnum range before
7191 converting to 'int'.
7193 * window.c (window_scroll_line_based, Frecenter):
7194 Check that an Emacs fixnum is in range before assigning it to 'int'.
7195 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
7196 values converted from Emacs fixnums.
7197 (Frecenter): Don't wrap around a line count if it is out of 'int'
7198 range; instead, treat it as an extreme value.
7199 (Fset_window_configuration, compare_window_configurations):
7200 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
7202 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
7203 that can exceed INT_MAX. Check that EMACS_INT value is in range
7204 before assigning it to the (possibly-narrower) index.
7205 (match_limit): Don't assume that a fixnum can fit in 'int'.
7207 * print.c (print_object): Use ptrdiff_t, not int, for index that can
7208 exceed INT_MAX.
7210 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
7211 (Fvertical_motion): Don't wrap around LINES values that don't fit
7212 in 'int'. Instead, treat them as extreme values. This is good
7213 enough for windows, which can't have more than INT_MAX lines anyway.
7215 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
7217 * Require libxml/parser.h to avoid compilation warning.
7219 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
7221 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
7222 since this reportedly can destroy thread storage.
7224 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
7226 * syntax.c (find_defun_start): Update all cache variables if
7227 exiting early (Bug#9401).
7229 2011-08-30 Eli Zaretskii <eliz@gnu.org>
7231 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
7233 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
7234 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
7235 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
7237 * term.c (tty_append_glyph): New function.
7238 (produce_stretch_glyph): Static function and its prototype deleted.
7240 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
7241 Add prototypes.
7243 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
7245 * image.c (parse_image_spec): Check for nonnegative, not for positive,
7246 when checking :margin (Bug#9390).
7247 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
7248 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
7249 so that the name doesn't mislead. All uses changed.
7251 2011-08-28 Johan Bockgård <bojohan@gnu.org>
7253 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
7254 set_tty_hooks.
7256 2011-08-27 Eli Zaretskii <eliz@gnu.org>
7258 * xdisp.c (move_it_to): Don't bail out early when reaching
7259 position beyond to_charpos, if we are scanning backwards.
7260 (move_it_vertically_backward): When DY == 0, make sure we get to
7261 the first character in the line after the newline.
7263 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
7265 * ccl.c: Improve and simplify overflow checking (Bug#9196).
7266 (ccl_driver): Do not generate an out-of-range pointer.
7267 (Fccl_execute_on_string): Remove unnecessary check for
7268 integer overflow, noted by Stefan Monnier in
7269 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
7270 Remove a FIXME that didn't need fixing.
7271 Simplify the newly-introduced buffer reallocation code.
7273 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
7275 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
7277 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
7279 Integer and memory overflow issues (Bug#9196).
7281 * doc.c (get_doc_string): Rework so that
7282 get_doc_string_buffer_size is the actual buffer size, rather than
7283 being 1 less than the actual buffer size; this makes xpalloc more
7284 convenient.
7286 * image.c (x_allocate_bitmap_record, cache_image):
7287 * xselect.c (Fx_register_dnd_atom):
7288 Simplify previous changes by using xpalloc.
7290 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
7291 since either will do and ptrdiff_t is convenient with xpalloc.
7293 * charset.c (charset_table_size)
7294 (struct charset_sort_data.priority): Now ptrdiff_t.
7295 (charset_compare): Don't overflow if priorities differ greatly.
7296 (Fsort_charsets): Don't assume list length fits in int.
7297 Check for size-calculation overflow when allocating sort data.
7298 (syms_of_charset): Allocate an initial charset table that is
7299 just under 64 KiB, to avoid problems with glibc malloc and mmap.
7301 * cmds.c (internal_self_insert): Check for size-calculation overflow.
7303 * composite.h (struct composition.glyph_len): Now int, not unsigned.
7304 The actual value is always <= INT_MAX, and leaving it unsigned made
7305 overflow checking harder.
7307 * dispextern.h (struct glyph_matrix.rows_allocated)
7308 (struct face_cache.size): Now ptrdiff_t, for convenience in use
7309 with xpalloc. The values are still always <= INT_MAX.
7311 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
7313 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
7314 (SAFE_NALLOCA): New macro.
7316 * region-cache.c (struct boundary.pos, find_cache_boundary)
7317 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
7318 (set_cache_region, invalidate_region_cache)
7319 (revalidate_region_cache, know_region_cache, region_cache_forward)
7320 (region_cache_backward, pp_cache):
7321 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
7322 so that ptrdiff_t * can be passed to xpalloc.
7323 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
7324 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
7325 (pp_cache): Don't assume cache_len fits in int.
7326 * region-cache.h: Adjust extern decls to match.
7328 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
7329 EMACS_INT, since either will do, for xpalloc.
7331 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
7332 (xnmalloc, xnrealloc, xpalloc): New functions.
7334 * bidi.c (bidi_shelve_header_size): New constant.
7335 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
7336 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
7338 * bidi.c (bidi_cache_shrink):
7339 * buffer.c (overlays_at, overlays_in, record_overlay_string)
7340 (overlay_strings):
7341 Don't update size of array until after memory allocation succeeds,
7342 because xmalloc/xrealloc may not return.
7343 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
7344 now that we have proper integer overflow checking.
7345 (record_overlay_string, overlay_strings): Catch overflows when
7346 calculating size of overlay_str_buf.
7348 * callproc.c (Fcall_process): Check for size overflow when
7349 calculating size of args2.
7350 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
7351 Normally we prefer signed values, but sticking with ptrdiff_t would
7352 require adding more-complicated checks.
7354 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
7355 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
7356 Redo buffer-overflow calculations to avoid integer overflow.
7357 Add a FIXME comment where memory seems to be over-allocated.
7359 * character.c (Fstring): Check for size-calculation overflow.
7361 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
7362 unnecessary integer overflow. Check for size overflow.
7363 (encode_coding_object): Don't update size until xmalloc succeeds.
7365 * composite.c (get_composition_id): Check for overflow in glyph
7366 length calculations.
7368 Integer and memory overflow fixes for display code.
7369 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
7370 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
7371 (scrolling_window): Check for overflow in size calculations.
7372 (line_draw_cost, realloc_glyph_pool, add_row_entry):
7373 Don't assume glyph table len fits in int.

7375 (row_table_size): Now ptrdiff_t, not int.
7376 (scrolling_window): Avoid overflow in size calculations.
7377 Don't update size until allocation succeeds.

7384 (get_doc_string): Check for size calculation overflow.
7385 Don't update size until allocation succeeds.
7386 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
7387 EMACS_INT, where ptrdiff_t will do.
7388 (Fsubstitute_command_keys): Check for string overflow.
7390 * editfns.c (set_time_zone_rule): Don't assume environment length
7391 fits in int.
7392 (message_length): Now ptrdiff_t, not int.
7393 (Fmessage_box): Don't update size until allocation succeeds.
7394 Don't assume message length fits in int.
7395 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
7397 * emacs.c (main): Do not reallocate argv, since there is a null at
7398 the end that can be overwritten, and this way there's no need to
7399 worry about size-calculation overflow.
7400 (sort_args): Check for size-calculation overflow.
7402 * eval.c (init_eval_once, grow_specpdl): Don't update size until
7403 alloc succeeds.
7404 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
7406 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
7407 (x_set_scroll_bar_width, x_figure_window_size):
7408 Check for integer overflow.
7409 (x_set_alpha): Do not assume XINT fits in int.
7411 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
7412 This is for the members text_lines, text_cols, total_lines, total_cols,
7413 where the system imposes an 'int' limit.
7415 * fringe.c (Fdefine_fringe_bitmap):
7416 Don't update size until alloc works.
7418 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
7419 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
7421 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
7422 Check for size-calculation overflow.
7423 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
7424 do, as we prefer signed integers.
7425 (id_to_widget.max_size, id_to_widget.used)
7426 (xg_store_widget_in_map, xg_remove_widget_from_map)
7427 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
7428 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
7429 Use and return ptrdiff_t, not int.
7430 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
7431 * gtkutil.h: Change prototypes to match the above.
7433 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
7434 are duplicate now that they've been promoted to lisp.h.
7435 (x_allocate_bitmap_record, x_alloc_image_color)
7436 (make_image_cache, cache_image, xpm_load):
7437 Don't update size until alloc is done.
7438 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
7439 (x_detect_edges):
7440 Check for size calculation overflow.
7441 (ct_colors_allocated_max): New constant.

7446 (read_char_x_menu_prompt, read_char_minibuf_menu_width)
7447 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
7448 Use ptrdiff_t, not int, to count maps.
7449 (read_char_minibuf_menu_prompt): Check for overflow in size
7450 calculations. Don't update size until allocation succeeds.
7451 Redo calculations to avoid overflow.
7452 * keyboard.h: Change prototypes to match the above.

7457 * keymap.h: Change prototypes to match the above.
7459 * lread.c (read1, init_obarray): Don't update size until alloc done.
7461 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.
7462 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.

7475 overflow. Don't bother calling xmalloc when xrealloc will do.
7477 * search.c (Freplace_match): Check for size calculation overflow.
7478 (Fset_match_data): Don't assume list lengths fit in 'int'.
7480 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
7481 for command line length. Do not attempt to address one before the
7482 beginning of an array, as that's not portable.
7484 * term.c (max_frame_lines): Remove; unused.
7485 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
7486 not int.
7487 (encode_terminal_code, calculate_costs): Check for size
7488 calculation overflow.

7494 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
7495 subtracting pointers.

7497 until alloc done.
7499 * tparam.c (tparam1): Use ptrdiff_t, not int, for sizes.

7509 * xfaces.c (lface_id_to_name_size, Finternal_make_lisp_face):
7510 Use ptrdiff_t, not int, for sizes.
7511 (Finternal_make_lisp_face, cache_face):
7512 Check for size calculation overflow.
7513 (cache_face): Treat size calculation overflows as if they were
7514 memory exhaustion (the usual treatment), rather than aborting.
7516 * xfns.c (x_encode_text, x_set_name_internal)
7517 (Fx_change_window_property): Use ptrdiff_t, not int, to count
7518 sizes, since they can exceed INT_MAX in size. Check for size

7522 (xg_select): Check for size calculation overflow.
7523 Don't update size until alloc done.
7525 * xrdb.c (get_environ_db): Don't assume path length fits in int,
7526 as sprintf is limited to int lengths.
7528 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
7529 (X_LONG_MIN): New macros.
7530 Use them to make the following changes clearer.
7531 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
7532 This change doesn't affect the value now, but it may help remind
7533 future maintainers not to raise the value too much later.
7534 (SELECTION_QUANTUM): Remove, replacing with ...
7535 (selection_quantum): ... new function, which avoids overflow.
7536 All uses changed.
7537 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
7538 assumption that selection length fits in 'int'.
7539 (x_reply_selection_request, x_handle_selection_request)
7540 (x_get_window_property, receive_incremental_selection)
7541 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
7542 (lisp_data_to_selection_data, clean_local_selection_data):
7543 Use ptrdiff_t, not int, to record length of selection.
7544 (x_reply_selection_request, x_get_window_property)
7545 (receive_incremental_selection, x_property_data_to_lisp):
7546 Redo calculations to avoid overflow.
7547 (x_reply_selection_request): When sending hint, ceiling it at
7548 X_LONG_MAX rather than relying on wraparound overflow to send
7549 something.
7550 (x_get_window_property, receive_incremental_selection)
7551 (lisp_data_to_selection_data, x_property_data_to_lisp):
7552 Check for size-calculation overflow.
7553 (x_get_window_property, receive_incremental_selection)
7554 (lisp_data_to_selection_data, Fx_register_dnd_atom):
7555 Don't store size until memory allocation succeeds.
7556 (x_get_window_property): Plug memory leak on memory exhaustion.
7557 Don't double-block input; malloc is safe here. Don't assume 2**34
7558 - 4 fits in unsigned long. Add an xassert to check
7559 XGetWindowProperty overflow. Be more careful about overflow
7560 calculations, and distinguish size from memory overflow better.
7561 (receive_incremental_selection): When tracing, don't assume
7562 unsigned int is less than INT_MAX.

7564 harmful) conversions of unsigned short to int.
7565 (lisp_data_to_selection_data): Don't assume that integers
7566 in the range -65535 through -1 fit in an X unsigned short.
7567 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
7568 result parameters unless successful. Rely on cons_to_unsigned
7569 to report problems with elements; the old code wasn't right anyway.
7570 (x_check_property_data): Check for int overflow; we cannot use
7571 a wider type due to X limits.
7572 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
7574 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
7576 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)
7577 (x_term_init): Check for size calculation overflow.
7578 (x_color_cells): Don't store size until memory allocation succeeds.
7579 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
7580 Don't assume alloca size is less than MAX_ALLOCA.
7581 (x_term_init): Don't assume length fits in int (sprintf is limited
7582 to int size).
7584 Use ptrdiff_t for composition IDs.
7585 * character.c (lisp_string_width):
7586 * composite.c (composition_table_size, n_compositions)
7587 (get_composition_id, composition_gstring_from_id):

7603 * image.c (xpm_get_color_table_h):
7604 * lisp.h (hash_lookup, hash_put):
7605 * minibuf.c (Ftest_completion):
7606 Use ptrdiff_t for hash table indexes, not int (which is too
7607 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
7608 32-bit --with-wide-int hosts).
7610 * charset.c (Fdefine_charset_internal): Check for integer overflow.
7611 Add a FIXME comment about memory leaks.
7612 (syms_of_charset): Don't assume xmalloc returns.
7614 Don't assume that stated character widths fit in int.
7615 * character.c (Fchar_width, c_string_width, lisp_string_width):
7616 * character.h (CHAR_WIDTH):
7617 * indent.c (MULTIBYTE_BYTES_WIDTH):
7618 Use sanitize_char_width to avoid undefined and/or bad behavior
7619 with outlandish widths.
7620 * character.h (sanitize_tab_width): Rename from sanitize_width,
7621 now that we have two such functions. All uses changed.
7622 (sanitize_char_width): New inline function.
7624 Don't assume that tab-width fits in int.
7625 * character.h (sanitize_width): New inline function.
7626 (SANE_TAB_WIDTH): New macro.

7628 * indent.c (sane_tab_width): Remove. All uses replaced by
7629 SANE_TAB_WIDTH (current_buffer).
7630 * xdisp.c (init_iterator): Use SANE_TAB_WIDTH.
7632 * fileio.c: Integer overflow issues with file modes.
7633 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
7635 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
7636 Remove unreachable code.

7639 * xterm.c: Don't go over XClientMessageEvent limit.
7640 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
7641 (x_send_scroll_bar_event): Likewise. Check that the size does not
7642 exceed limits imposed by XClientMessageEvent, as well as the usual
7643 ptrdiff_t and size_t limits.
7645 * keyboard.c: Overflow, signedness and related fixes.
7646 (make_lispy_movement): Use same integer type in forward decl
7647 that is used in the definition.
7648 (read_key_sequence, keyremap_step):
7649 Change bufsize argument back to int, undoing my 2011-03-30 change.
7650 We prefer signed types, and int is wide enough here.
7651 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
7652 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
7653 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
7654 length, not size_t. Use ptrdiff_t for index, not int.
7655 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
7656 possibility of integer overflow.
7658 Overflow, signedness and related fixes for images.
7660 * dispextern.h (struct it.stack[0].u.image.image_id)
7661 (struct_it.image_id, struct image.id, struct image_cache.size)

7667 * nsmenu.m (update_frame_tool_bar):
7668 * xdisp.c (calc_pixel_width_or_height):
7669 * xfns.c (image_cache_refcount):
7670 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
7671 on typical 64-bit hosts.
7673 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
7674 (x_bitmap_pixmap, x_create_x_image_and_pixmap):

7679 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
7680 (lookup_image): Remove unnecessary tests.
7681 (xbm_image_p): Locals are now of int, not EMACS_INT,
7682 since parse_image_check makes sure they fit into int.
7683 (png_load, gif_load, svg_load_image):
7684 Prefer int to unsigned where either will do.
7685 (tiff_handler): New function, combining the cores of the
7686 old tiff_error_handler and tiff_warning_handler.
7687 This function is rewritten to use vsnprintf and thereby avoid
7688 stack buffer overflows. It uses only the features of vsnprintf
7689 that are common to both POSIX and native Microsoft.
7690 (tiff_error_handler, tiff_warning_handler): Use it.
7691 (tiff_load, gif_load, imagemagick_load_image):
7692 Don't assume :index value fits in 'int'.
7693 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
7694 (imagemagick_load_image): Check that crop parameters fit into
7695 the integer types that MagickCropImage accepts. Don't assume
7696 Vimagemagick_render_type has a nonnegative value. Don't assume
7697 size_t fits in 'long'.
7698 (gs_load): Use printmax_t to print the widest integers possible.
7699 Check for integer overflow when computing image height and width.
7701 2011-08-26 Eli Zaretskii <eliz@gnu.org>

7704 will be invisible in the resulting window. (Bug#9324)
7706 2011-08-25 Eli Zaretskii <eliz@gnu.org>
7708 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
7709 the display spec is of the form `(space ...)'.
7710 (handle_display_spec): Return the value returned by
7711 handle_single_display_spec, not just 1 or zero.
7712 (handle_single_display_spec): If the display spec is of the form
7713 `(space ...)', and specifies display in the text area, return 2
7714 rather than 1.
7715 (try_cursor_movement): Check for the need to scroll more
7716 accurately, and prefer exact match for point under bidi.
7717 Don't advance `row' beyond the last row of the window.
7719 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
7720 into disp_prop; all users changed.
7722 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
7723 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
7724 for the text covered by the display property.
7726 2011-08-25 Chong Yidong <cyd@stupidchicken.com>
7728 * buffer.c (Fbury_buffer_internal): Rename from Funrecord_buffer.

7734 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
7735 buffers, return left-to-right.
7736 (set_cursor_from_row): Consider candidate row a win if its glyph
7737 represents a newline and point is on that newline. Fixes cursor
7738 positioning on the newline at EOL of R2L text within L2R
7739 paragraph, and vice versa.
7740 (try_cursor_movement): Check continued rows, in addition to
7741 continuation rows. Fixes unwarranted scroll when point enters a
7742 continued line of R2L text within an L2R paragraph, or vice versa.
7743 (cursor_row_p): Consider the case of point being equal to
7744 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
7745 from the end of a short line to the beginning of a continued line
7746 of R2L text within L2R paragraph.
7747 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for

7757 a character.
7759 2011-08-23 Chong Yidong <cyd@stupidchicken.com>
7761 * nsfont.m (ns_otf_to_script): Fix typo.
7763 2011-08-22 Kenichi Handa <handa@m17n.org>
7765 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
7766 extra slot even if the purpose is char-code-property-table.
7768 2011-08-23 Eli Zaretskii <eliz@gnu.org>
7770 * xdisp.c (redisplay_window): When computing centering_position,
7771 account for the height of the header line. (Bug#8874)
7773 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
7774 instead of CHAR_TO_BYTE. Fixes a crash when a completion
7775 candidate is selected by the mouse, and that candidate has a
7776 composed character under the mouse.
7778 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
7779 coordinates reported by pos-visible-in-window-p for a composed
7780 character in column zero.
7782 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
7784 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
7786 2011-08-22 Eli Zaretskii <eliz@gnu.org>
7788 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
7789 consider it a hit if to_charpos is anywhere in the range of the
7790 composed buffer positions.
7792 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
7794 * image.c (gif_load): Don't assume that each subimage has the same
7795 dimensions as the base image. Handle disposal method that is
7796 "undefined" by the gif spec (Bug#9335).
7798 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
7800 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
7801 (Fcondition_case): Document `debug' symbol in error handler.
7803 2011-08-19 Eli Zaretskii <eliz@gnu.org>
7805 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
7806 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
7807 from an Org mode buffer to a Speedbar frame.
7809 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
7810 a composition, take its buffer position from IT->cmp_it.charpos.
7811 Fixes cursor positioning at the beginning of a line that begins
7812 with a composed character.
7814 2011-08-18 Eli Zaretskii <eliz@gnu.org>
7816 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
7817 character bidirectional type, use STRONG_L instead. Fixes crashes
7818 in a buffer produced by `describe-categories'.
7820 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
7821 members before the level stack, so they would be saved and
7822 restored when copying iterator state. Fixes incorrect reordering
7823 around TABs covered by display properties.
7825 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
7827 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

7832 (internal_condition_case_2, internal_condition_case_n):
7833 Remove unnecessary aborts (Bug#9081).
7835 2011-08-17 Eli Zaretskii <eliz@gnu.org>
7837 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
7838 has no `load' handler, try opening the file locally. (Bug#9311)
7840 2011-08-16 Ken Brown <kbrown@cornell.edu>
7842 * gmalloc.c: Expand comment.
7844 2011-08-16 Eli Zaretskii <eliz@gnu.org>
7846 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
7847 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.
7849 2011-08-16 Ken Brown <kbrown@cornell.edu>
7851 Fix memory allocation problems in Cygwin build (Bug#9273).
7853 * unexcw.c ( __malloc_initialized): Declare external variable.

7892 * process.c (create_process): Call setup_process_coding_systems
7893 after the pid of the process is set to -1 (Bug#8162).
7895 2011-08-14 Eli Zaretskii <eliz@gnu.org>
7897 * xdisp.c (move_it_in_display_line_to): Don't invoke
7898 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
7899 ppos_it. Fixes vertical cursor motion when line beginning is
7900 covered by an image. (Bug#9296)
7902 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
7904 * nsterm.h (ns_run_ascript): Declare.
7905 (NSAPP_DATA2_RUNASSCRIPT): Define.
7907 * nsfns.m (as_script, as_result, as_status): New static variables.
7908 (ns_run_ascript): New function.
7909 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
7910 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
7911 the event loop. Get status from as_status (Bug#7276).
7913 * nsterm.m (sendEvent): If event is NSApplicationDefined and
7914 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
7915 the event loop (Bug#7276).
7917 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
7919 * gnutls.c (QCgnutls_bootprop_priority)

7940 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
7941 (Fnetwork_interface_list): Allocate in increments of bytes instead
7942 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
7943 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
7944 sockaddr.
7945 (struct ifflag_def): notrailers is smart on OSX.
7946 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
7947 Get hardware address with getifaddrs if available.
7949 2011-08-12 Eli Zaretskii <eliz@gnu.org>
7951 * xdisp.c (iterate_out_of_display_property): xassert that
7952 IT->position is set to within IT->object's boundaries. Break from
7953 the loop as soon as EOB is reached; avoids infloops in redisplay
7954 when IT->position is set up wrongly due to some bug.
7955 Set IT->current to match the bidi iterator unconditionally.
7956 (push_display_prop): Allow GET_FROM_STRING as IT->method on
7957 entry. Force push_it to save on the stack the current
7958 buffer/string position, to be restored by pop_it. Fix flags in
7959 the iterator structure wrt the object coming from a display
7960 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
7961 properties. (Bug#9284)
7963 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
7965 * fontset.c (fontset_get_font_group): Add proper type checks.

7975 2011-08-08 Eli Zaretskii <eliz@gnu.org>
7977 * xdisp.c (forward_to_next_line_start): Allow to use the
7978 no-display-properties-and-no-overlays under bidi display.
7979 Set disp_pos in the bidi iterator to avoid searches for display
7980 properties and overlays.
7982 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
7984 * editfns.c (Fset_time_zone_rule): Document relationship with the
7985 setenv function.

7988 the font entity extracted from the cache (Bug#8109).
7990 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
7992 * composite.c (autocmp_chars): Don't reset point. That is done by
7993 restore_point_unwind (Bug#5984).
7995 2011-08-07 Juri Linkov <juri@jurta.org>
7997 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
7998 to show the arg `TIME' instead of `TIMEVAL'.
8000 2011-08-06 Eli Zaretskii <eliz@gnu.org>
8002 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
8003 display property strides EOL and includes a newline, as in
8004 longlines-mode. (Bug#9254)
8005 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
8006 word-wrap under bidirectional display. (Bug#9224)
8008 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
8009 is non-zero, even if the data buffer is NULL. Fixes a crash in
8010 vertical-motion with longlines-mode. (Bug#9254)
8012 2011-08-05 Eli Zaretskii <eliz@gnu.org>
8014 * bidi.c <bidi_cache_total_alloc>: Now static.
8015 (bidi_initialize): Initialize bidi_cache_total_alloc.
8017 * xdisp.c (display_line): Release buffer allocated for shelved bidi
8018 cache. (Bug#9221)
8020 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
8021 amount allocated this far in `bidi_cache_total_alloc'.
8022 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
8023 non-zero, only free the data buffer without restoring the cache
8024 contents. All callers changed.
8026 * dispextern.h (bidi_unshelve_cache): Update prototype.
8028 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
8029 (move_it_in_display_line, move_it_to)
8030 (move_it_vertically_backward, move_it_by_lines): Replace the call
8031 to xfree to an equivalent call to bidi_unshelve_cache.
8032 (move_it_in_display_line_to): Fix logic of returning
8033 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
8035 2011-08-05 Eli Zaretskii <eliz@gnu.org>
8037 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
8038 came from a string character with a `cursor' property. (Bug#9229)
8040 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
8042 * Makefile.in (LIB_PTHREAD): New variable.
8043 (LIBES): Add LIB_PTHREAD (Bug#9216).
8045 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
8046 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
8048 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
8050 * regex.c (re_iswctype): Remove some redundant boolean conversions.
8052 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
8054 * xterm.c (x_find_topmost_parent): New function.
8055 (x_set_frame_alpha): Find topmost parent window with
8056 x_find_topmost_parent and set the property there also (bug#9181).
8057 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
8059 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
8061 * callproc.c (Fcall_process): Avoid vfork clobbering
8062 the local vars buffer, coding_systems, current_dir.
8064 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
8066 * keymap.c (Fmake_composed_keymap): Move to subr.el.
8068 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
8070 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
8071 so that it is not optimized away.
8073 * xdisp.c (compute_display_string_pos): Remove unused local.
8075 2011-08-02 Eli Zaretskii <eliz@gnu.org>
8077 Fix slow cursor motion and scrolling in large buffers with
8078 selective display, like Org Mode buffers. (Bug#9218)
8080 * dispextern.h (struct bidi_it): New member disp_prop_p.
8082 * xdisp.c: Remove one-slot cache of display string positions.
8083 (compute_display_string_pos): Accept an additional argument
8084 DISP_PROP_P; callers changed. Scan at most 5K characters forward
8085 for a display string or property. If found, set DISP_PROP_P
8086 non-zero.
8088 * bidi.c (bidi_fetch_char): Accept an additional argument
8089 DISP_PROP_P, and pass it to compute_display_string_pos.
8090 Only handle text covered by a display string if DISP_PROP_P is returned
8091 non-zero. All callers of bidi_fetch_char changed.
8093 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
8095 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
8097 2010-12-03 Don March <don@ohspite.net>
8099 * keymap.c (Fdefine_key): Fix non-prefix key error message when
8100 last character M-[char] is translated to ESC [char] (bug#7541).
8102 2011-08-02 Kenichi Handa <handa@m17n.org>
8104 * lisp.h (uniprop_table): Extern it.
8106 * chartab.c (uniprop_table): Make it non-static.
8108 2011-08-01 Eli Zaretskii <eliz@gnu.org>
8110 * xdisp.c (forward_to_next_line_start): Accept additional argument
8111 BIDI_IT_PREV, and store into it the state of the bidi iterator had
8112 on the newline.
8113 (reseat_at_next_visible_line_start): Use the bidi iterator state
8114 returned by forward_to_next_line_start to restore the state of
8115 it->bidi_it after backing up to previous newline. (Bug#9212)
8117 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
8119 * regex.c (re_comp): Protoize.
8120 (re_exec): Fix return type.
8121 (regexec): Fix type of `ret'. (Bug#9203)
8123 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8125 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
8126 This is needed if max-image-size is a floating-point number.
8128 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8130 * print.c (print_object): Print empty symbol as ##.
8132 * lread.c (read1): Read ## as empty symbol.
8134 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8136 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
8137 setting frame foreground color (Bug#9175).
8138 (x_set_background_color): Likewise.
8140 * nsmenu.m (-setText): Size tooltip dimensions precisely to
8141 contents (Bug#9176).
8142 (EmacsTooltip -init): Remove bezels and add shadows to
8143 tooltip windows.
8145 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
8146 or scroll bar (Bug#8470).
8148 * nsfont.m (nsfont_open): Remove assignment to voffset and
8149 unnecessary vars hshink, expand, hd, full_height, min_height.
8150 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
8152 * nsterm.h (nsfont_info): Remove voffset field.
8154 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8156 Implement strike-through and overline on NextStep (Bug#8863).
8158 * nsfont.m (nsfont_open): Use underline position provided by font,
8159 instead of hard-coded value of 2.
8160 (nsfont_draw): Call ns_draw_text_decoration instead.
8162 * nsterm.h: Add declaration for ns_draw_text_decoration.
8164 * nsterm.m (ns_draw_text_decoration): New function for drawing
8165 underline, overline, and strike-through.
8166 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
8167 ns_draw_text_decoration. Change treatment of cursor drawing to
8168 accommodate underlining, etc.
8170 2011-07-28 Eli Zaretskii <eliz@gnu.org>
8172 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
8173 default.
8175 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8177 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
8178 Without this fix, if a signal arrives just after memory fills up,
8179 'malloc' might be invoked reentrantly.
8181 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
8182 In other words, assume that every image size is allowed, on non-X
8183 hosts. This assumption is probably wrong, but it lets Emacs compile.
8185 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8187 * regex.c (re_iswctype): Convert return values to boolean.
8189 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
8191 * xdisp.c (compute_display_string_pos): Don't use cached display
8192 string position if the buffer had its restriction changed.
8193 (Bug#9184)
8195 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8197 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
8199 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8201 Integer signedness and overflow and related fixes. (Bug#9079)
8203 * bidi.c: Integer size and overflow fixes.
8204 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
8205 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
8206 (bidi_cache_find_level_change, bidi_cache_ensure_space)
8207 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
8208 (bidi_find_other_level_edge):
8209 Use ptrdiff_t instead of EMACS_INT where either will do.
8210 This works better on 32-bit hosts configured --with-wide-int.
8211 (bidi_cache_ensure_space): Check for size-calculation overflow.
8212 Use % rather than repeated addition, for better worst-case speed.
8213 Don't set bidi_cache_size until after xrealloc returns, because it
8214 might not return.
8215 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
8216 (bidi_cache_ensure_space): Also check that the bidi cache size
8217 does not exceed that of the largest Lisp string or buffer. See Eli
8218 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
8220 * alloc.c (__malloc_size_t): Remove.
8221 All uses replaced by size_t. See Andreas Schwab's note
8222 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
8224 * image.c: Improve checking for integer overflow.
8225 (check_image_size): Assume that f is nonnull, since
8226 it is always nonnull in practice. This is one less thing to
8227 worry about when checking for integer overflow later.
8228 (x_check_image_size): New function, which checks for integer
8229 overflow issues inside X.
8230 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
8231 This removes the need for a memory_full check.
8232 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
8233 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
8234 (xbm_read_bitmap_data): Change locals back to 'int', since
8235 their values must fit in 'int'.
8236 (xpm_load_image, png_load, tiff_load):
8237 Invoke x_create_x_image_and_pixmap earlier,
8238 to avoid much needless work if the image is too large.
8239 (tiff_load): Treat overly large images as if
8240 x_create_x_image_and_pixmap failed, not as malloc failures.
8241 (gs_load): Use x_check_image_size.
8243 * gtkutil.c: Omit integer casts.
8244 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
8245 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
8247 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
8249 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
8250 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
8251 would wrongly return t on a 64-bit host.
8253 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
8254 The plain *_OVERFLOW macros run afoul of GCC bug 49705
8255 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
8256 and therefore cause GCC to emit a bogus diagnostic in some cases.
8258 * image.c: Integer signedness and overflow and related fixes.
8259 This is not an exhaustive set of fixes, but it's time to
8260 record what I've got.
8261 (lookup_pixel_color, check_image_size): Remove redundant decls.
8262 (check_image_size): Don't assume that arbitrary EMACS_INT values
8263 fit in 'int', or that arbitrary 'double' values fit in 'int'.
8264 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
8265 (tiff_load, imagemagick_load_image):
8266 Check for overflow in size calculations.
8267 (x_create_x_image_and_pixmap): Remove unnecessary test for
8268 xmalloc returning NULL; that can't happen.
8269 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
8270 (xpm_color_bucket): Use better integer hashing function.
8271 (xpm_cache_color): Don't possibly over-allocate memory.
8272 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
8273 (gif_memory_source):
8274 Use ptrdiff_t, not int or size_t, to record sizes.
8275 (png_load): Don't assume values greater than 2**31 fit in 'int'.
8276 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
8277 either works, as we prefer signed integers.
8278 (tiff_read_from_memory, tiff_write_from_memory):
8279 Return tsize_t, not size_t, since that's what the TIFF API wants.
8280 (tiff_read_from_memory): Don't fail simply because the read would
8281 go past EOF; instead, return a short read.
8282 (tiff_load): Omit no-longer-needed casts.
8283 (Fimagemagick_types): Don't assume size fits into 'int'.
8285 Improve hashing quality when configured --with-wide-int.
8286 * fns.c (hash_string): New function, taken from sxhash_string.
8287 Do not discard information about ASCII character case; this
8288 discarding is no longer needed.
8289 (sxhash-string): Use it. Change sig to match it. Caller changed.
8290 * lisp.h: Declare it.
8291 * lread.c (hash_string): Remove, since we now use fns.c's version.
8292 The fns.c version returns a wider integer if --with-wide-int is
8293 specified, so this should help the quality of the hashing a bit.
8295 * emacs.c: Integer overflow minor fix.
8296 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
8297 Define only if GNU_LINUX.
8298 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
8300 * dispnew.c: Integer signedness and overflow fixes.
8301 Remove unnecessary forward decls, that were a maintenance hassle.
8302 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
8303 All uses changed.
8304 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
8305 (scrolling_window): Use ptrdiff_t, not int, for byte count.
8306 (prepare_desired_row, line_draw_cost):
8307 Use int, not unsigned, where either works.
8308 (save_current_matrix, restore_current_matrix):
8309 Use ptrdiff_t, not size_t, where either works.
8310 (init_display): Check for overflow more accurately, and without
8311 relying on undefined behavior.
8313 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
8314 Remove, replacing with the new symbols in lisp.h. All uses changed.
8315 * fileio.c (make_temp_name):
8316 * filelock.c (lock_file_1, lock_file):
8317 * xdisp.c (message_dolog):
8318 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
8319 Use pMd etc. instead.
8320 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
8321 replacing the pWIDE etc. symbols removed from editfns.c.
8323 * keyboard.h (num_input_events): Now uintmax_t.
8324 This is (very slightly) less likely to mess up due to wraparound.
8325 All uses changed.
8327 * buffer.c: Integer signedness fixes.
8328 (alloc_buffer_text, enlarge_buffer_text):
8329 Use ptrdiff_t rather than size_t when either will do, as we prefer
8330 signed integers.
8332 * alloc.c: Integer signedness and overflow fixes.
8333 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
8334 (__malloc_size_t): Default to size_t, not to int.
8335 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
8336 (Fgarbage_collect, mark_object_loop_halt, mark_object):
8337 Prefer ptrdiff_t to size_t when either would do, as we prefer
8338 signed integers.
8339 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
8340 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
8341 Now const. Initialize with values that are in range even if char
8342 is signed.
8343 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
8344 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
8345 These functions do the right thing with sizes > 2**32.
8346 (check_depth): Now ptrdiff_t, not int.
8347 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
8348 Adjust to new way of storing sizes. Check for size overflow bugs
8349 in rest of code.
8350 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
8351 slightly wrong anyway, as it missed one instance of
8352 XMALLOC_OVERRUN_CHECK_OVERHEAD.
8353 (refill_memory_reserve): Omit needless cast to size_t.
8354 (mark_object_loop_halt): Mark as externally visible.
8356 * xselect.c: Integer signedness and overflow fixes.
8357 (Fx_register_dnd_atom, x_handle_dnd_message):
8358 Use ptrdiff_t, not size_t, since we prefer signed.
8359 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
8360 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
8361 x_dnd_atoms_size and x_dnd_atoms_length.
8363 * doprnt.c: Prefer signed to unsigned when either works.
8364 * eval.c (verror):
8365 * doprnt.c (doprnt):
8366 * lisp.h (doprnt):
8367 * xdisp.c (vmessage):
8368 Use ptrdiff_t, not size_t, when using or implementing doprnt,
8369 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
8370 prefer signed arithmetic to avoid comparison confusion.
8371 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
8372 but is a bit tricky.
8374 Assume freestanding C89 headers, string.h, stdlib.h.
8375 * data.c, doprnt.c, floatfns.c, print.c:
8376 Include float.h unconditionally.
8377 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
8378 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
8379 * regex.c: Likewise for stddef.h, string.h.
8380 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
8381 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
8382 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
8383 (STDC_HEADERS): Remove obsolete defines.
8384 * sysdep.c: Include limits.h unconditionally.
8386 Assume support for memcmp, memcpy, memmove, memset.
8387 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
8388 * regex.c (memcmp, memcpy):
8389 Remove; we assume C89 now.
8391 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
8392 (__malloc_safe_bcopy): Remove; no longer needed.
8394 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
8395 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
8396 well either way, and we prefer signed to unsigned.
8398 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
8400 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
8401 closes the connection while we're reading (bug#9182).
8403 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
8405 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
8406 are specified (Bug#9168).
8408 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
8410 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
8411 Found by GCC static checking and --with-wide-int on a 32-bit host.
8413 2011-07-25 Eli Zaretskii <eliz@gnu.org>
8415 * xdisp.c (compute_display_string_pos): Fix logic of caching
8416 previous display string position. Initialize cached_prev_pos to
8417 -1. Fixes slow-down at the beginning of a buffer.
8419 2011-07-24 Eli Zaretskii <eliz@gnu.org>
8421 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
8422 for attrs[LFACE_FONTSET_INDEX].
8424 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
8426 * xml.c (parse_region): Remove unused local
8427 that was recently introduced.
8429 2011-07-23 Eli Zaretskii <eliz@gnu.org>
8431 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
8432 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
8434 * xdisp.c (move_it_in_display_line_to): Record the best matching
8435 position for TO_CHARPOS while scanning the line, and restore it on
8436 exit if none of the characters scanned was an exact match.
8437 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
8438 when exact match is impossible due to invisible text, and the
8439 lines are truncated.
8441 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
8443 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
8444 for OSX >= 10.7.
8446 2011-07-22 Eli Zaretskii <eliz@gnu.org>
8448 Fix a significant slow-down of cursor motion with C-n, C-p,
8449 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
8450 auto-repeat under bidi redisplay in fontified buffers.
8451 * xdisp.c (compute_stop_pos_backwards): New function.
8452 (next_element_from_buffer): Call compute_stop_pos_backwards to
8453 find a suitable prev_stop when we find ourselves before
8454 base_level_stop.
8455 (reseat): Don't look for prev_stop, as that could mean a very long
8456 run.
8457 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
8458 <cached_disp_overlay_modiff>: Cache for last found display string
8459 position.
8460 (compute_display_string_pos): Return the cached position if asked
8461 about the same buffer in the same area of character positions, and
8462 the buffer wasn't changed since the time the display string
8463 position was cached.
8465 2011-07-22 Eli Zaretskii <eliz@gnu.org>
8467 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
8468 is an integer, which is important for empty lines. (Bug#9149)
8470 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
8472 * frame.c (Fmodify_frame_parameters): In tty case, update the
8473 default face if necessary (Bug#4238).
8475 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
8477 * editfns.c (Fstring_to_char): No need to explain what a character
8478 is in the docstring (Bug#6576).
8480 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
8482 * xml.c (parse_region): Make sure we always return a tree.
8484 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
8486 * xml.c (parse_region): If a document contains only comments,
8487 return that, too.
8489 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
8491 * xml.c (make_dom): Return comments, too.
8493 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
8495 Port to OpenBSD.
8496 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
8497 and the surrounding thread.
8498 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
8499 rather than fgets, and retry after EINTR. Otherwise, 'emacs
8500 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
8501 timer goes off.
8502 * s/openbsd.h (BROKEN_SIGIO): Define.
8503 * unexelf.c (unexec) [__OpenBSD__]:
8504 Don't update the .mdebug section of the Alpha COFF symbol table.
8506 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
8508 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
8509 (bug#8460).
8511 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
8513 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
8514 This fixes some race conditions on the permissions of any newly
8515 created file.
8517 * alloc.c (valid_pointer_p): Use pipe, not open.
8518 This fixes some permissions issues when debugging.
8520 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
8521 If fchown fails to set both uid and gid, try to set just gid,
8522 as that is sometimes allowed. Adjust the file's mode to eliminate
8523 setuid or setgid bits that are inappropriate if fchown fails.
8525 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
8527 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
8528 to compare Lisp_Objects.
8529 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
8530 global_gnutls_log_level, don't mistake it for a Lisp_Object.
8531 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
8533 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
8535 * lread.c (read_integer): Unread even EOF character.
8536 (read1): Likewise. Properly record start position of symbol.
8538 * lread.c (read1): Read `#:' as empty uninterned symbol if no
8539 symbol character follows.
8541 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
8543 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
8544 This works around a problem with the previous change to Fcopy_file.
8545 Recent glibc declares fchown with __attribute__((warn_unused_result)),
8546 and without this change, GCC might complain about discarding
8547 fchown's return value.
8549 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
8551 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
8553 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
8555 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
8557 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
8559 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
8560 it's used from the C level.
8562 * process.c: Use the same condition for POLL_FOR_INPUT in both
8563 keyboard.c and process.c (bug#1858).
8565 2011-07-09 Lawrence Mitchell <wence@gmx.li>
8567 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
8568 (Fgnutls_boot): Use it.
8570 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
8572 * doc.c (Fsubstitute_command_keys): Revert last change.
8574 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
8576 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
8577 quotes the next character, and doesn't affect other longer
8578 sequences (bug#8935).
8580 * lread.c (syms_of_lread): Clarify that is isn't only
8581 `eval-buffer' and `eval-defun' that's affected by
8582 `lexical-binding' (bug#8460).
8584 2011-07-15 Eli Zaretskii <eliz@gnu.org>
8586 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
8587 bidi redisplay when a line includes both an image and is truncated.
8589 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
8591 Fix minor problems found by static checking.
8592 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
8593 (elsz): Now a signed constant, not a size_t var. We prefer signed
8594 types to unsigned, to avoid integer comparison confusion. Without
8595 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
8596 "cannot optimize loop, the loop counter may overflow", a symptom
8597 of the confusion.
8598 * indent.c (Fvertical_motion): Mark locals as initialized.
8599 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
8601 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
8603 * search.c (Fre_search_backward): Mention `case-fold-search' in
8604 all the re_search_* functions (bug#8138).
8606 * keyboard.c (Fopen_dribble_file): Document when the file is
8607 closed (bug#8056).
8609 2011-07-14 Eli Zaretskii <eliz@gnu.org>
8611 * bidi.c (bidi_dump_cached_states): Fix format of displaying
8612 bidi_cache_idx.
8614 Support bidi reordering of display and overlay strings.

8624 buffer position was specified. Initialize paragraph_embedding to
8625 L2R.
8626 (reseat_to_string): Initialize the bidi iterator.
8627 (display_string): If we need to ignore text properties of
8628 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
8629 original value of -1 will not work with bidi.)
8630 (compute_display_string_pos): First arg is now struct
8631 `text_pos *'; all callers changed. Support display properties on
8632 Lisp strings.
8633 (compute_display_string_end): Support display properties on Lisp
8634 strings.
8635 (init_iterator, reseat_1, reseat_to_string): Initialize the
8636 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
8637 when iterating on a string not from display properties).
8638 (compute_display_string_pos, compute_display_string_end):
8639 Fix calculation of the object to scan. Fixes an error when using
8640 arrow keys.
8641 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
8642 base_level_stop; instead, set base_level_stop to BEGV.
8643 Fixes crashes in vertical-motion.
8644 (next_element_from_buffer): Improve commentary for when
8645 the iterator is before prev_stop.
8646 (init_iterator): Initialize bidi_p from the default value of
8647 bidi-display-reordering, not from buffer-local value. Use the
8648 buffer-local value only if initializing for buffer iteration.
8649 (handle_invisible_prop): Support invisible properties on strings
8650 that are being bidi-reordered.
8651 (set_iterator_to_next): Support bidi reordering of C strings and

8654 strings.
8655 (handle_stop_backwards): Support Lisp strings as well.
8656 (display_string): Support display of R2L glyph rows.
8657 Use IT_STRING_CHARPOS when displaying from a Lisp string.
8658 (init_iterator): Don't initialize it->bidi_p for strings
8659 here.
8660 (reseat_to_string): Initialize it->bidi_p for strings here.
8661 (next_element_from_string, next_element_from_c_string)
8662 (next_element_from_buffer): Add xassert's for correspondence

8666 (next_element_from_c_string): Handle the case of the first string
8667 character that is not the first one in the visual order.
8668 (get_visually_first_element): New function, refactored from common
8669 parts of next_element_from_buffer, next_element_from_string, and
8670 next_element_from_c_string.
8671 (tool_bar_lines_needed, redisplay_tool_bar)
8672 (display_menu_bar): Force left-to-right direction. Add a FIXME
8673 comment for making that be controlled by a user option.
8674 (push_it, pop_it): Save and restore the state of the
8675 bidi iterator. Save and restore the bidi_p flag.
8676 (pop_it): Iterate out of display property for string iteration as

8678 (iterate_out_of_display_property): Support iteration over strings.
8679 (handle_single_display_spec): Set up it->bidi_it for iteration
8680 over a display string, and call bidi_init_it.
8681 (handle_single_display_spec, next_overlay_string)
8682 (get_overlay_strings_1, push_display_prop): Set up the bidi
8683 iterator for displaying display or overlay strings.
8684 (forward_to_next_line_start): Don't use the shortcut if
8685 bidi-iterating.
8686 (back_to_previous_visible_line_start): If handle_display_prop
8687 pushed the iterator stack, restore the internal state of the bidi
8688 iterator by calling bidi_pop_it same number of times.
8689 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
8690 and we are bidi-iterating, don't decrement the iterator position;
8691 instead, set the first_elt flag in the bidi iterator, to produce
8692 the same effect.
8693 (reseat_1): Remove redundant setting of string_from_display_prop_p.
8694 (push_display_prop): xassert that we are iterating a buffer.
8695 (push_it, pop_it): Save and restore paragraph_embedding member.
8696 (handle_single_display_spec, next_overlay_string)
8697 (get_overlay_strings_1, reseat_1, reseat_to_string)
8698 (push_display_prop): Set up the `unibyte' member of bidi_it.string
8699 correctly. Don't assume unibyte strings are not bidi-reordered.

8701 (compute_display_string_end): Fix handling the case of C string.
8702 (push_it, pop_it): Save and restore from_disp_prop_p.

8705 (get_overlay_strings_1): Reset the from_disp_prop_p flag.
8706 (pop_it): Call iterate_out_of_display_property only if we are
8707 popping after iteration over a string that came from a display
8708 property. Fix a typo in popping stretch info. Add an assertion
8709 for verifying that the iterator position is in sync with the bidi
8710 iterator.

8712 (push_display_prop): Fix initialization of paragraph direction for
8713 string when that of the parent object is not yet determined.
8714 (reseat_1): Call bidi_init_it to resync the bidi
8715 iterator with IT's position. (Bug#7616)
8716 (find_row_edges): If ROW->start.pos gives position
8717 smaller than min_pos, use it as ROW->minpos. (Bug#7616)
8718 (handle_stop, back_to_previous_visible_line_start, reseat_1):
8719 Reset the from_disp_prop_p flag.
8720 (SAVE_IT, RESTORE_IT): New macros.
8721 (pos_visible_p, face_before_or_after_it_pos)
8722 (back_to_previous_visible_line_start)
8723 (move_it_in_display_line_to, move_it_in_display_line)
8724 (move_it_to, move_it_vertically_backward, move_it_by_lines)
8725 (try_scrolling, redisplay_window, display_line): Use them when
8726 saving a temporary copy of the iterator and restoring it back.
8727 (back_to_previous_visible_line_start, reseat_1)
8728 (init_iterator): Empty the bidi cache "stack".
8729 (move_it_in_display_line_to): If iterator ended up at
8730 EOL, but we never saw any buffer positions smaller than
8731 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
8732 motion in bidi-reordered lines.
8733 (move_it_in_display_line_to): Record prev_method and prev_pos
8734 immediately before the call to set_iterator_to_next. Fixes cursor
8735 motion in bidi-reordered lines with stretch glyphs and strings
8736 displayed in margins. (Bug#8133) (Bug#8867)
8737 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
8738 TO_CHARPOS.
8739 (pos_visible_p): Support positions in bidi-reordered lines.
8740 Save and restore bidi cache.
8742 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.
8743 (bidi_paragraph_info): Delete unused struct.
8744 (bidi_cache_idx, bidi_cache_last_idx): Declare EMACS_INT.
8745 (bidi_cache_start): New variable.
8746 (bidi_cache_reset): Reset bidi_cache_idx to bidi_cache_start, not
8747 to zero.
8748 (bidi_cache_fetch_state, bidi_cache_search)
8749 (bidi_cache_find_level_change, bidi_cache_iterator_state)
8750 (bidi_cache_find, bidi_peek_at_next_level)

8763 (bidi_resolve_explicit, bidi_type_of_next_char): ignore_bn_limit
8764 can now be zero (for strings); special values 0 and -1 were
8765 changed to -1 and -2, respectively.
8766 (bidi_char_at_pos): New function.
8767 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak):

8778 (bidi_initialize): Initialize the bidi cache start stack pointer.
8779 (bidi_cache_ensure_space): New function, refactored from part of

8793 All variables related to cache indices are now EMACS_INT.
8795 * dispextern.h (struct bidi_string_data): New structure.
8796 (struct bidi_it): New member `string'. Make flag members be 1-bit
8797 fields, and put them last in the struct.
8798 (compute_display_string_pos, compute_display_string_end):
8799 Update prototypes.
8800 (bidi_push_it, bidi_pop_it): Add prototypes.
8801 (struct iterator_stack_entry): New members bidi_p,
8802 paragraph_embedding, and from_disp_prop_p.
8803 (struct it): Member bidi_p is now a bit field 1 bit wide.
8804 (bidi_shelve_cache, bidi_unshelve_cache):
8805 Declare prototypes.
8807 * .gdbinit (xvectype, xvector, xcompiled, xchartable, xboolvector)

8849 (x_handle_selection_clear,x_clear_frame_selections):
8850 Pass Qx_lost_selection_functions rather than
8851 Vx_lost_selection_functions to Frun_hook_with_args.
8853 2011-07-13 Paul Eggert <eggert@cs.ucla.edu>
8855 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
8856 The old code sometimes used this field without initializing it.
8858 * alloc.c (gc_sweep): Don't read past end of array.
8859 In theory, the old code could also have corrupted Emacs internals,
8860 though it'd be very unlikely.
8862 2011-07-12 Andreas Schwab <schwab@linux-m68k.org>
8864 * character.c (Fcharacterp): Don't advertise optional ignored
8865 argument. (Bug#4026)
8867 2011-07-12 Lars Magne Ingebrigtsen <larsi@gnus.org>
8869 * keymap.c (syms_of_keymap): Clarify that "modifier" is "modifier
8870 key" (bug#4257).
8872 * window.c (Fset_window_start): Doc fix (bug#4199).
8873 (Fset_window_hscroll): Ditto.
8875 2011-07-12 Paul Eggert <eggert@cs.ucla.edu>

8890 are the mini-buffer and the echo area (bug#3320).
8892 * term.c (init_tty): Remove support for supdup, c10 and perq
8893 terminals, which are no longer supported (bug#1482).

9123 (clone_per_buffer_values): Don't assume that

9125 This isn't true in general, and it's particularly not true
9126 if Emacs is configured with --with-wide-int.
9127 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):

9164 Random fixes. E.g., (random) never returned negative values.
9165 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
9166 subseconds part to the entropy, as that's a bit more random.
9167 Prefer signed to unsigned, since the signedness doesn't matter and
9168 in general we prefer signed. When given a limit, use a
9169 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
9170 latter isn't right if USE_2_TAGS_FOR_INTS.
9171 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
9172 not 0..VALMASK. Don't discard "excess" bits that random () returns.
9174 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
9176 * textprop.c (text_property_stickiness):

9185 This is more efficient than Ffile_directory_p and avoids a minor race.
9187 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
9189 * buffer.c (Foverlay_put): Say what the return value is
9190 (bug#7835).
9192 * fileio.c (barf_or_query_if_file_exists): Check first if the file
9193 is a directory before asking whether to use the file name
9194 (bug#7564).
9195 (barf_or_query_if_file_exists): Make the "File is a directory"
9196 error be more correct.
9198 * fns.c (Frequire): Remove the mention of the .gz files, since
9199 that's installation-specific, but keep the mention of
9200 `get-load-suffixes'.
9202 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
9204 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

9215 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
9216 Also (re)move comments that are misplaced or no longer relevant.
9218 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>

9279 (syms_of_keymap): Defsubr make-composed-keymap.
9280 * keyboard.c (menu_bar_items): Use map_keymap_canonical.
9281 (parse_menu_item): Trivial simplification.
9283 2011-07-01 Glenn Morris <rgm@gnu.org>

9313 xg_select.
9315 2011-07-01 Paul Eggert <eggert@cs.ucla.edu>
9317 * eval.c (struct backtrace): Simplify and port the data structure.
9318 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
9319 signed bit field, as this assumption is not portable and it makes
9320 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
9321 "char debug_on_exit : 1" as this is not portable either; instead,
9322 use the portable "unsigned int debug_on_exit : 1". Remove unused
9323 member evalargs. Remove obsolete comments about cc bombing out.
9325 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

9417 2011-06-25 Paul Eggert <eggert@cs.ucla.edu>
9419 Use gnulib's dup2 module instead of rolling our own.

9487 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
9489 Integer and buffer overflow fixes (Bug#8873).
9491 * print.c (printchar, strout): Check for string overflow.
9492 (PRINTPREPARE, printchar, strout):
9493 Don't set size unless allocation succeeds.
9495 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
9496 for sizes. Check for string overflow more accurately.
9497 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
9499 * macros.c: Integer and buffer overflow fixes.
9500 * keyboard.h (struct keyboard.kbd_macro_bufsize):
9501 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

9507 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
9509 * lread.c: Integer overflow fixes.
9510 (read_integer): Radix is now EMACS_INT, not int,
9511 to improve quality of diagnostics for out-of-range radices.
9512 Calculate buffer size correctly for out-of-range radices.
9513 (read1): Check for integer overflow in radices, and in
9514 read-circle numbers.
9515 (read_escape): Avoid int overflow.
9516 (Fload, openp, read_buffer_size, read1)
9517 (substitute_object_recurse, read_vector, read_list, map_obarray):

9531 (read_escape): Check for hex character overflow.
9533 2011-06-22 Leo Liu <sdl.web@gmail.com>
9535 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
9536 Move to minibuffer.el.
9538 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
9540 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
9541 The following patches are for when GLYPH_DEBUG && !XASSERT.
9542 * dispextern.h (trace_redisplay_p, dump_glyph_string):
9543 * dispnew.c (flush_stdout):
9544 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
9545 Mark as externally visible.
9546 * dispnew.c (check_window_matrix_pointers): Now static.
9547 * dispnew.c (window_to_frame_vpos):
9548 * xfns.c (unwind_create_frame):
9549 * xterm.c (x_check_font): Remove unused local.
9550 * scroll.c (CHECK_BOUNDS):
9551 * xfaces.c (cache_fache): Rename local to avoid shadowing.
9552 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
9553 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
9554 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
9555 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
9556 Now static.
9557 (debug_method_add): Use va_list and vsprintf rather than relying
9558 on undefined behavior with wrong number of arguments.
9559 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
9560 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
9561 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
9562 since we're not interested in debugging glyphs with old libraries.
9563 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
9564 GCC 4.6.0's static checking.
9566 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
9568 Integer overflow and signedness fixes (Bug#8873).

9580 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
9581 (.bitmaps_last):
9582 * xfaces.c (load_pixmap):
9583 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
9584 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
9585 (.bitmaps_last, struct x_output.icon_bitmap):
9586 Use ptrdiff_t, not int, for bitmap indexes.
9587 (x_allocate_bitmap_record): Check for size overflow.
9588 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
9590 Use ptrdiff_t, not int, for overlay counts.
9591 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
9592 * editfns.c (overlays_around, get_pos_property):
9593 * textprop.c (get_char_property_and_overlay):
9594 * xdisp.c (next_overlay_change, note_mouse_highlight):
9595 * xfaces.c (face_at_buffer_position):
9596 * buffer.c (OVERLAY_COUNT_MAX): New macro.
9597 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
9598 (Fnext_overlay_change, Fprevious_overlay_change)
9599 (mouse_face_overlay_overlaps, Foverlays_in):
9600 Use ptrdiff_t, not int, for sizes.
9601 (overlays_at, overlays_in): Check for size-calculation overflow.
9603 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
9605 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
9606 (x_session_initialize): Do not assume string length fits in int.
9608 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
9609 This is unlikely, but can occur if DPI is outlandish.
9611 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
9612 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
9614 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
9615 * xrdb.c (magic_file_p, search_magic_path):
9616 Omit last arg SUFFIX; it was always 0. All callers changed.
9617 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.

9624 * xdisp.c (message_log_check_duplicate): Return intmax_t,
9625 not unsigned long, as we prefer signed integers. All callers changed.
9626 Detect integer overflow in repeat count.
9627 (message_dolog): Don't assume print length fits in 39 bytes.
9628 (display_mode_element): Don't assume strlen fits in int.
9630 * termcap.c: Don't assume sizes fit in int and never overflow.
9631 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
9632 (gobble_line): Check for size-calculation overflow.
9634 * minibuf.c (Fread_buffer):
9635 * lread.c (intern, intern_c_string):
9636 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
9637 Don't assume string length fits in int.

9649 * filelock.c: Fix some buffer overrun and integer overflow issues.
9650 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
9651 Reformulate so as not to need the command string.
9652 Invoke gzip -cd rather than gunzip, as it's more portable.
9653 (lock_info_type, lock_file_1, lock_file):
9654 Don't assume pid_t and time_t fit in unsigned long.
9655 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
9656 (current_lock_owner): Prefer signed type for sizes.
9657 Use memcpy, not strncpy, where memcpy is what is really wanted.
9658 Don't assume (via atoi) that time_t and pid_t fit in int.
9659 Check for time_t and/or pid_t out of range, e.g., via a network share.
9660 Don't alloca where an auto var works fine.
9662 * fileio.c: Fix some integer overflow issues.
9663 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
9664 Don't assume string length fits in int.
9665 (directory_file_name): Don't assume string length fits in long.

9667 length is less than 20.
9669 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
9671 * coding.c (make_subsidiaries): Don't assume string length fits in int.
9673 * callproc.c (child_setup): Rewrite to avoid two strlen calls.

9687 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
9689 * lread.c (invalid_syntax): Omit length argument.
9690 All uses changed. This doesn't fix a bug, but it simplifies the
9691 code away from its former Hollerith-constant appearance, and it's
9692 one less 'int' to worry about when looking at integer-overflow issues.
9693 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
9695 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
9696 This didn't break anything, but it didn't help either.
9697 It's confusing to put a bogus integer in a place where the actual
9698 value does not matter.
9699 (LIST_END_P): Remove unused macro and its bogus comment.
9700 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
9702 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
9703 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
9704 implementation.
9705 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
9706 We prefer signed types, and the value cannot exceed the EMACS_INT
9707 range anyway (because otherwise the length would not be representable).
9708 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
9709 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
9710 This avoids a GCC warning when WIDE_EMACS_INT.
9712 * indent.c (sane_tab_width): New function.
9713 (current_column, scan_for_column, Findent_to, position_indentation)
9714 (compute_motion): Use it. This is just for clarity.
9715 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
9717 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
9719 * lisp.h (lint_assume): New macro.
9720 * composite.c (composition_gstring_put_cache):
9721 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
9723 * editfns.c, insdel.c:
9724 Omit unnecessary forward decls, to simplify future changes.
9726 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
9728 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
9730 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
9731 Use much-faster test for byte-length change.
9732 Don't assume string byte-length fits in 'int'.
9733 Check that character arg fits in 'int'.
9734 (mapcar1): Declare byte as byte, for clarity.
9736 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
9738 * fns.c (concat): Catch string overflow earlier.
9739 Do not rely on integer wraparound.
9741 * dispextern.h (struct it.overlay_strings_charpos)
9742 (struct it.selective): Now EMACS_INT, not int.
9743 * xdisp.c (forward_to_next_line_start)
9744 (back_to_previous_visible_line_start)
9745 (reseat_at_next_visible_line_start, next_element_from_buffer):
9746 Don't arbitrarily truncate the value of 'selective' to int.
9748 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
9750 * composite.c: Don't truncate sizes to 'int'.
9751 (composition_gstring_p, composition_reseat_it)
9752 (composition_adjust_point): Use EMACS_INT, not int.
9753 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
9754 not EMACS_UINT, for indexes.
9756 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
9758 * buffer.c: Include <verify.h>.
9759 (struct sortvec.priority, struct sortstr.priority):
9760 Now EMACS_INT, not int.
9761 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
9762 (struct sortstr.size, record_overlay_string)
9763 (struct sortstrlist.size, struct sortlist.used):
9764 Don't truncate size to int.
9765 (record_overlay_string): Check for size-calculation overflow.
9766 (init_buffer_once): Check at compile-time, not run-time.
9768 2011-06-22 Jim Meyering <meyering@redhat.com>
9770 Don't leak an XBM-image-sized buffer
9771 * image.c (xbm_load): Free the image buffer after using it.
9773 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
9775 Port to Sun C.
9776 * composite.c (find_automatic_composition): Omit needless 'return 0;'
9777 that Sun C diagnosed.
9778 * fns.c (secure_hash): Fix pointer signedness issue.
9779 * intervals.c (static_offset_intervals): New function.
9780 (offset_intervals): Use it.
9782 2011-06-21 Leo Liu <sdl.web@gmail.com>
9784 * deps.mk (fns.o):
9785 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
9786 sha512.h.
9788 * fns.c (secure_hash): Rename from crypto_hash_function and change
9789 the first arg to accept symbols.
9790 (Fsecure_hash): New primitive.
9791 (syms_of_fns): New symbols.
9793 2011-06-20 Deniz Dogan <deniz@dogan.se>
9795 * process.c (Fset_process_buffer): Clarify return value in
9796 docstring.
9798 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
9800 * dispnew.c (add_window_display_history): Use BVAR.

9803 (check_window_end, dump_glyph_matrix, dump_glyph)
9804 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
9806 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
9807 Likewise.
9809 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
9810 check till after the cache is created in init_frame_faces.
9812 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
9814 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
9816 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
9818 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
9819 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
9820 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
9822 Improve buffer-overflow checking (Bug#8873).
9823 * fileio.c (Finsert_file_contents):
9824 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
9825 Remove the old (too-loose) buffer overflow checks.
9826 They weren't needed, since make_gap checks for buffer overflow.
9827 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
9828 The old code merely checked for Emacs fixnum overflow, and relied
9829 on undefined (wraparound) behavior. The new code avoids undefined
9830 behavior, and also checks for ptrdiff_t and/or size_t overflow.
9832 * editfns.c (Finsert_char): Don't dump core with very negative counts.
9833 Tune. Don't use wider integers than needed. Don't use alloca.
9834 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
9836 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
9838 * insdel.c, lisp.h (buffer_overflow): New function.
9839 (insert_from_buffer_1, replace_range, replace_range_2):
9840 * insdel.c (make_gap_larger):
9841 * editfns.c (Finsert_char):
9842 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
9844 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
9846 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
9848 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
9850 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
9851 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
9853 * fileio.c: Don't assume EMACS_INT fits in off_t.
9854 (emacs_lseek): New static function.
9855 (Finsert_file_contents, Fwrite_region): Use it.
9856 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
9858 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
9860 * fns.c: Don't overflow int when computing a list length.
9861 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
9862 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
9863 truncation on 64-bit hosts. Check for QUIT every
9864 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
9865 faster and is responsive enough.
9866 (Flength): Report an error instead of overflowing an integer.
9867 (Fsafe_length): Return a float if the value is not representable
9868 as a fixnum. This shouldn't happen except in contrived situations.
9869 (Fnthcdr, Fsort): Don't assume list length fits in int.
9870 (Fcopy_sequence): Don't assume vector length fits in int.
9872 * alloc.c: Check that resized vectors' lengths fit in fixnums.
9873 (header_size, word_size): New constants.
9874 (allocate_vectorlike): Don't check size overflow here.
9875 (allocate_vector): Check it here instead, since this is the only
9876 caller of allocate_vectorlike that could cause overflow.
9877 Check that the new vector's length is representable as a fixnum.
9879 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
9880 The previous code was bogus. For example, next_almost_prime (32)
9881 returned 39, which is undesirable as it is a multiple of 3; and
9882 next_almost_prime (24) returned 25, which is a multiple of 5 so
9883 why was the code bothering to check for multiples of 7?
9885 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
9887 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
9889 Variadic C functions now count arguments with ptrdiff_t.
9890 This partly undoes my 2011-03-30 change, which replaced int with size_t.
9891 Back then I didn't know that the Emacs coding style prefers signed int.
9892 Also, in the meantime I found a few more instances where arguments
9893 were being counted with int, which may truncate counts on 64-bit
9894 machines, or EMACS_INT, which may be unnecessarily wide.
9895 * lisp.h (struct Lisp_Subr.function.aMANY)
9896 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
9897 Arg counts are now ptrdiff_t, not size_t.
9898 All variadic functions and their callers changed accordingly.
9899 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
9900 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
9901 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
9902 * callint.c (Fcall_interactively): Check arg count for overflow,
9903 to avoid potential buffer overrun. Use signed char, not 'int',
9904 for 'varies' array, so that we needn't bother to check its size
9905 calculation for overflow.
9906 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
9907 * eval.c (apply_lambda):
9908 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
9909 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
9910 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
9912 * callint.c (Fcall_interactively): Don't use index var as event count.
9914 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
9915 * mem-limits.h (SIZE): Remove; no longer used.
9917 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
9919 Remove unnecessary casts.
9920 * xterm.c (x_term_init):
9921 * xfns.c (x_set_border_pixel):
9922 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
9923 These aren't needed now that we assume ANSI C.
9925 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
9926 It's more likely to cause problems (due to unsigned overflow)
9927 than to cure them.
9929 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
9931 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
9933 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
9935 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
9937 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
9939 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
9941 GLYPH_CODE_FACE returns EMACS_INT, not int.
9942 * dispextern.h (merge_faces):
9943 * xfaces.c (merge_faces):
9944 * xdisp.c (get_next_display_element, next_element_from_display_vector):
9945 Don't assume EMACS_INT fits in int.
9947 * character.h (CHAR_VALID_P): Remove unused parameter.
9948 * fontset.c, lisp.h, xdisp.c: All uses changed.
9950 * editfns.c (Ftranslate_region_internal): Omit redundant test.
9952 * fns.c (concat): Minor tuning based on overflow analysis.
9953 This doesn't fix any bugs. Use int to hold character, instead
9954 of constantly refetching from Emacs object. Use XFASTINT, not
9955 XINT, for value known to be a character. Don't bother comparing
9956 a single byte to 0400, as it's always less.
9958 * floatfns.c (Fexpt):
9959 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
9961 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
9962 for characters.
9964 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
9966 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
9967 Without this fix, on a 64-bit host (aset S 0 4294967386) would
9968 incorrectly succeed when S was a string, because 4294967386 was
9969 truncated before it was used.
9971 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
9972 Otherwise, an out-of-range integer could cause undefined behavior
9973 on a 64-bit host.
9975 * composite.c: Use int, not EMACS_INT, for characters.
9976 (fill_gstring_body, composition_compute_stop_pos): Use int, not
9977 EMACS_INT, for values that are known to be in character range.
9978 This doesn't fix any bugs but is the usual style inside Emacs and
9979 may generate better code on 32-bit machines.
9981 Make sure a 64-bit char is never passed to ENCODE_CHAR.
9982 This is for reasons similar to the recent CHAR_STRING fix.
9983 * charset.c (Fencode_char): Check that character arg is actually
9984 a character. Pass an int to ENCODE_CHAR.
9985 * charset.h (ENCODE_CHAR): Verify that the character argument is no
9986 wider than 'int', as a compile-time check to prevent future regressions
9987 in this area.
9989 * character.c (char_string): Remove unnecessary casts.
9991 Make sure a 64-bit char is never passed to CHAR_STRING.
9992 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
9993 by silently ignoring the top 32 bits, allowing some values
9994 that were far too large to be valid characters.
9995 * character.h: Include <verify.h>.
9996 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
9997 arguments are no wider than unsigned, as a compile-time check
9998 to prevent future regressions in this area.
9999 * data.c (Faset):
10000 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
10001 (Fsubst_char_in_region):
10002 * fns.c (concat):
10003 * xdisp.c (decode_mode_spec_coding):
10004 Adjust to CHAR_STRING's new requirement.
10005 * editfns.c (Finsert_char, Fsubst_char_in_region):
10006 * fns.c (concat): Check that character args are actually
10007 characters. Without this test, these functions did the wrong
10008 thing with wildly out-of-range values on 64-bit hosts.
10010 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
10011 These casts should not be needed on 32-bit hosts, either.
10012 * keyboard.c (read_char):
10013 * lread.c (Fload): Remove casts to unsigned.
10015 * lisp.h (UNSIGNED_CMP): New macro.
10016 This fixes comparison bugs on 64-bit hosts.
10017 (ASCII_CHAR_P): Use it.
10018 * casefiddle.c (casify_object):
10019 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
10020 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
10021 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
10022 * dispextern.h (FACE_FROM_ID):
10023 * keyboard.c (read_char): Use UNSIGNED_CMP.
10025 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
10026 not to EMACS_INT, to avoid GCC warning.
10028 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
10030 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
10031 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
10032 isn't needed on 32-bit machines.
10034 * buffer.c (Fgenerate_new_buffer_name):
10035 Use EMACS_INT for count, not int.
10036 (advance_to_char_boundary): Return EMACS_INT, not int.
10038 * data.c (Qcompiled_function): Now static.
10040 * window.c (window_body_lines): Now static.
10042 * image.c (gif_load): Rename local to avoid shadowing.
10044 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
10045 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
10046 * alloc.c (make_save_value): Integer argument is now of type
10047 ptrdiff_t, not int.
10048 (mark_object): Use ptrdiff_t, not int.
10049 * lisp.h (pD): New macro.
10050 * print.c (print_object): Use it.
10052 * alloc.c: Use EMACS_INT, not int, to count objects.
10053 (total_conses, total_markers, total_symbols, total_vector_size)
10054 (total_free_conses, total_free_markers, total_free_symbols)
10055 (total_free_floats, total_floats, total_free_intervals)
10056 (total_intervals, total_strings, total_free_strings):
10057 Now EMACS_INT, not int. All uses changed.
10058 (Fgarbage_collect): Compute overall total using a double, so that
10059 integer overflow is less likely to be a problem. Check for overflow
10060 when converting back to an integer.
10061 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
10062 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
10063 These were 'int' variables that could overflow on 64-bit hosts;
10064 they were never used, so remove them instead of repairing them.
10065 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
10066 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
10067 Previously, this ceilinged at INT_MAX, but that doesn't work on
10068 64-bit machines.
10069 (allocate_pseudovector): Don't use EMACS_INT when int would do.
10071 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
10072 (allocate_vectorlike): Check for ptrdiff_t overflow.
10073 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
10074 when a (possibly-narrower) signed value would do just as well.
10075 We prefer using signed arithmetic, to avoid comparison confusion.
10077 * alloc.c: Catch some string size overflows that we were missing.
10078 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
10079 for convenience in STRING_BYTES_MAX.
10080 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
10081 The definition here is exact; the one in lisp.h was approximate.
10082 (allocate_string_data): Check for string overflow. This catches
10083 some instances we weren't catching before. Also, it catches
10084 size_t overflow on (unusual) hosts where SIZE_MAX <= min
10085 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
10086 and ptrdiff_t and EMACS_INT are both 64 bits.
10088 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
10089 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
10090 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
10092 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
10094 * alloc.c (Fmake_string): Check for out-of-range init.
10096 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
10098 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
10100 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
10102 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
10103 xg_get_default_scrollbar_width.
10105 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
10106 (int_gtk_range_get_value): Move to the scroll bar part of the file.
10107 (style_changed_cb): Call update_theme_scrollbar_width and call
10108 x_set_scroll_bar_default_width and xg_frame_set_char_size for
10109 all frames (Bug#8505).
10110 (xg_create_frame_widgets): Call emacs_fixed_new if HAVE_GTK3 (Bug#8505).
10111 Call gtk_window_set_resizable if HAVE_GTK3.
10112 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
10113 and height if HAVE_GTK3 (Bug#8505).
10114 (scroll_bar_width_for_theme): New variable.
10115 (update_theme_scrollbar_width): New function.
10116 (xg_get_default_scrollbar_width): Move code to
10117 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
10118 (xg_initialize): Call update_theme_scrollbar_width.
10120 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
10122 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
10124 2011-06-12 Martin Rudalics <rudalics@gmx.at>
10126 * frame.c (make_frame): Call other_buffer_safely instead of
10127 other_buffer.
10129 * window.c (temp_output_buffer_show): Call display_buffer with
10130 second argument Vtemp_buffer_show_specifiers and reset latter
10131 immediately after the call.
10132 (Vtemp_buffer_show_specifiers): New variable.
10133 (auto_window_vscroll_p, next_screen_context_lines)
10134 (Vscroll_preserve_screen_position): Remove leading asterisks from
10135 doc-strings.
10137 2011-06-12 Paul Eggert <eggert@cs.ucla.edu>
10139 Fix minor problems found by GCC 4.6.0 static checking.
10140 * buffer.c (Qclone_number): Remove for now, as it's unused.
10141 (record_buffer, Funrecord_buffer): Rename local to avoid shadowing.
10142 (record_buffer): Remove unused local.
10143 * frame.c (other_visible_frames, frame_buffer_list): Now static.
10144 (set_frame_buffer_list): Remove; unused.
10145 * frame.h (other_visible_frames): Remove decl.
10146 * keyboard.h (menu_items_inuse): Declare only if USE_GTK || USE_MOTIF.
10147 * lisp.h (frame_buffer_list, set_frame_buffer_list): Remove decls.
10148 (add_gpm_wait_descriptor, delete_gpm_wait_descriptor): Declare only
10149 if HAVE_GPM.
10150 * menu.c (menu_items_inuse): Now static unless USE_GTK || USE_MOTIF.
10151 * process.c (add_gpm_wait_descriptor, delete_gpm_wait_descriptor):
10152 Define only if HAVE_GPM.
10153 * widget.c (EmacsFrameResize, emacsFrameClassRec): Now static.
10154 (update_hints_inhibit): Remove; never set. All uses removed.
10155 * widgetprv.h (emacsFrameClassRec): Remove decl.
10156 * window.c (delete_deletable_window): Now returns void, since it
10157 wasn't returning anything.
10158 (compare_window_configurations): Remove unused locals.
10159 * xfns.c (x_set_scroll_bar_default_width): Remove unused locals.
10160 * xmenu.c (x_menu_set_in_use): Define only if USE_GTK || USE_MOTIF.
10161 (dialog_selection_callback) [!USE_GTK]: Prefer intptr_t for integers
10162 the same widths as pointers. This follows up on the 2011-05-06 patch.
10163 * xterm.c (x_alloc_lighter_color_for_widget): Define only if USE_LUCID.
10164 * xterm.h: Likewise.
10165 (x_menu_set_in_use): Declare only if USE_GTK || USE_MOTIF.
10167 2011-06-12 Juanma Barranquero <lekktu@gmail.com>
10169 * makefile.w32-in: Update dependencies.
10170 (LISP_H): Add lib/intprops.h.
10172 2011-06-11 Chong Yidong <cyd@stupidchicken.com>
10174 * image.c (gif_load): Add animation frame delay to the metadata.
10175 (syms_of_image): Use DEFSYM. New symbol `delay'.
10177 2011-06-11 Martin Rudalics <rudalics@gmx.at>
10179 * window.c (delete_deletable_window): Re-add.
10180 (Fset_window_configuration): Rewrite to handle dead buffers and
10181 consequently deletable windows.
10182 (window_tree, Fwindow_tree): Remove. Supply functionality in
10183 window.el.
10184 (compare_window_configurations): Simplify code.
10186 2011-06-11 Andreas Schwab <schwab@linux-m68k.org>
10188 * image.c (imagemagick_load_image): Fix type mismatch.
10189 (Fimagemagick_types): Likewise.
10191 * window.h (replace_buffer_in_windows): Declare.
10193 2011-06-11 Martin Rudalics <rudalics@gmx.at>
10195 * buffer.c: New Lisp objects Qbuffer_list_update_hook and
10196 Qclone_number. Remove external declaration of Qdelete_window.
10197 (Fbuffer_list): Rewrite doc-string. Minor restructuring of
10198 code.
10199 (Fget_buffer_create, Fmake_indirect_buffer, Frename_buffer):
10200 Run Qbuffer_list_update_hook if allowed.
10201 (Fother_buffer): Rewrite doc-string. Major rewrite for new
10202 buffer list implementation.
10203 (other_buffer_safely): New function.
10204 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by
10205 calls to replace_buffer_in_windows and
10206 replace_buffer_in_windows_safely. Run Qbuffer_list_update_hook
10207 if allowed.
10208 (record_buffer): Inhibit quitting and rewrite using quittable
10209 functions. Run Qbuffer_list_update_hook if allowed.
10210 (Frecord_buffer, Funrecord_buffer): New functions.
10211 (switch_to_buffer_1, Fswitch_to_buffer): Remove.
10212 Move switch-to-buffer to window.el.
10213 (bury-buffer): Move to window.el.
10214 (Vbuffer_list_update_hook): New variable.
10216 * lisp.h (other_buffer_safely): Add prototype in buffer.c
10217 section.
10219 * window.h (resize_frame_windows): Move up in code.
10220 (Fwindow_frame): Remove EXFUN.
10221 (replace_buffer_in_all_windows): Remove prototype.
10222 (replace_buffer_in_windows_safely): Add prototype.
10224 * window.c: Declare Qdelete_window static again. Move down
10225 declaration of select_count.
10226 (Fnext_window, Fprevious_window): Rewrite doc-strings.
10227 (Fother_window): Move to window.el.
10228 (window_loop): Remove DELETE_BUFFER_WINDOWS and UNSHOW_BUFFER
10229 cases. Add REPLACE_BUFFER_IN_WINDOWS_SAFELY case.
10230 (Fdelete_windows_on, Freplace_buffer_in_windows): Move to
10231 window.el.
10232 (replace_buffer_in_windows): Implement by calling

10668 (bidi_resolve_explicit, bidi_resolve_weak):
10669 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
10670 bidirectional text is supported only in multibyte buffers.
10671 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
10672 it to initialize the frame_window_p member of struct bidi_it.
10673 (bidi_cache_iterator_state, bidi_resolve_explicit_1)
10674 (bidi_resolve_explicit, bidi_resolve_weak)
10675 (bidi_level_of_next_char, bidi_move_to_visually_next): Abort if
10676 bidi_it->nchars is non-positive.
10677 (bidi_level_of_next_char): Don't try to lookup the cache for the
10678 next/previous character if nothing is cached there yet, or if we
10679 were just reseat()'ed to a new position.
10681 * xdisp.c (set_cursor_from_row): Set start and stop points
10682 according to the row's direction when priming the loop that looks
10683 for the glyph on which to display cursor.
10684 (single_display_spec_intangible_p): Function deleted.
10685 (display_prop_intangible_p): Reimplement to call
10686 handle_display_spec instead of single_display_spec_intangible_p.
10687 Accept 3 additional arguments needed by handle_display_spec.
10688 This fixes incorrect cursor motion across display property with complex
10689 values: lists, `(when COND...)' forms, etc.
10690 (single_display_spec_string_p): Support property values that are
10691 lists with the argument STRING its top-level element.
10692 (display_prop_string_p): Fix the condition for processing a
10693 property that is a list to be consistent with handle_display_spec.
10694 (handle_display_spec): New function, refactored from the
10695 last portion of handle_display_prop.
10696 (compute_display_string_pos): Accept additional argument
10697 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
10698 value of a `display' property is a "replacing spec".
10699 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
10700 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
10701 the display property, but just return a value indicating whether
10702 the display property will replace the characters it covers.
10703 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
10704 frame_window_p members of struct bidi_it.
10705 (compute_display_string_pos, compute_display_string_end):
10706 New functions.
10707 (push_it): Accept second argument POSITION, where pop_it should
10708 jump to continue iteration.
10709 (reseat_1): Initialize bidi_it.disp_pos.
10711 * keyboard.c (adjust_point_for_property): Adjust the call to
10712 display_prop_intangible_p to its new signature.
10714 * dispextern.h (struct bidi_it): New member frame_window_p.
10715 (bidi_init_it): Update prototypes.
10716 (display_prop_intangible_p): Update prototype.
10717 (compute_display_string_pos, compute_display_string_end):
10718 Declare prototypes.
10719 (struct bidi_it): New members nchars and disp_pos. ch_len is now
10720 EMACS_INT.
10722 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
10724 Malloc failure behavior now depends on size of allocation.
10725 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
10726 * lisp.h: Change signatures accordingly.
10727 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
10728 All callers changed. (Bug#8762)
10730 * gnutls.c: Use Emacs's memory allocators.
10731 Without this change, the gnutls library would invoke malloc etc.
10732 directly, which causes problems on non-SYNC_INPUT hosts, and which
10733 runs afoul of improving memory_full behavior. (Bug#8761)
10734 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
10735 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
10736 xfree instead of the default malloc, realloc, free.
10737 (Fgnutls_boot): No need to check for memory allocation failure,
10738 since xmalloc does that for us.
10740 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
10741 * category.c (hash_get_category_set):
10742 * ccl.c (ccl_driver):
10743 * charset.c (Fdefine_charset_internal):

10747 * composite.h (struct composition.hash_index):
10748 * dispextern.h (struct image.hash):
10749 * fns.c (next_almost_prime, larger_vector, cmpfn_eql)
10750 (cmpfn_equal, cmpfn_user_defined, hashfn_eq, hashfn_eql)
10751 (hashfn_equal, hashfn_user_defined, make_hash_table)
10752 (maybe_resize_hash_table, hash_lookup, hash_put)
10753 (hash_remove_from_table, hash_clear, sweep_weak_table, SXHASH_COMBINE)
10754 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
10755 (Fsxhash, Fgethash, Fputhash, Fmaphash):
10756 * image.c (make_image, search_image_cache, lookup_image)
10757 (xpm_put_color_table_h):
10758 * lisp.h (struct Lisp_Hash_Table):
10759 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
10760 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
10761 for hashes and hash indexes, instead of 'unsigned' and 'int'.
10762 * alloc.c (allocate_vectorlike):
10763 Check for overflow in vector size calculations.
10764 * ccl.c (ccl_driver):
10765 Check for overflow when converting EMACS_INT to int.
10766 * fns.c, image.c: Remove unnecessary static decls that would otherwise
10767 need to be updated by these changes.
10768 * fns.c (make_hash_table, maybe_resize_hash_table):
10769 Check for integer overflow with large hash tables.
10770 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
10771 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
10772 (SXHASH_REDUCE): New macro.
10773 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
10774 Use it instead of discarding useful hash info with large hash values.
10775 (sxhash_float): New function.
10776 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
10777 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
10778 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
10779 Rewrite to use FIXNUM_BITS, as this simplifies things.
10780 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
10781 Adjust signatures to match updated version of code.
10782 (consing_since_gc): Now EMACS_INT, since a single hash table can
10783 use more than INT_MAX bytes.
10785 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
10787 Make it possible to build with GCC-4.6+ -O2 -flto.
10789 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
10791 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
10793 * minibuf.c (get_minibuffer, read_minibuf_unwind):
10794 Call minibuffer-inactive-mode.
10796 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
10798 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
10799 Update dependencies.
10801 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
10803 * data.c (init_data): Remove code for UTS, this system is not
10804 supported anymore.
10806 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
10808 Don't force ./temacs to start in terminal mode.
10810 * frame.c (make_initial_frame): Initialize faces in all cases, not
10811 only when CANNOT_DUMP is defined.
10812 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
10814 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
10816 * dispnew.c (add_window_display_history): Use const for the string
10817 pointer. Remove declaration, not needed.
10819 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
10821 Use 'inline', not 'INLINE'.
10822 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
10823 * alloc.c, fontset.c (INLINE): Remove.
10824 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
10825 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
10826 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
10827 * gmalloc.c (register_heapinfo): Use inline unconditionally.
10828 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
10830 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
10832 Make it possible to run ./temacs.
10834 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
10835 syms_of_callproc does the same thing. Remove test for
10836 "initialized", do it in the caller.
10837 * emacs.c (main): Avoid calling set_initial_environment when dumping.
10839 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
10841 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
10842 (read_minibuf): Use get_minibuffer.
10843 (syms_of_minibuf): Use DEFSYM.
10844 (Qmetadata): New var.
10845 * data.c (Qbuffer): Don't make it static.
10846 (syms_of_data): Use DEFSYM.
10848 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
10850 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
10851 (CCL_CODE_MIN): New macro.
10853 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
10855 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
10857 * eval.c (Qdebug): Now static.
10858 * lisp.h (Qdebug): Remove decl. This reverts a part of the
10859 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
10860 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
10862 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
10864 * image.c: Various fixes to ImageMagick code comments.
10865 (Fimagemagick_types): Doc fix.
10867 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
10869 Minor fixes prompted by GCC 4.6.0 warnings.
10871 * xselect.c (converted_selections, conversion_fail_tag): Now static.
10873 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
10874 (x_clipboard_manager_save_all): Move extern decl to ...
10875 * xterm.h: ... here, so that it can be checked for consistency.
10877 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
10879 * xselect.c (x_clipboard_manager_save_frame)
10880 (x_clipboard_manager_save_all): New functions.
10881 (Fx_clipboard_manager_save): Lisp function deleted.
10883 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
10884 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
10886 * xterm.h: Update prototype.
10888 2011-05-28 William Xu <william.xwl@gmail.com>
10890 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
10891 exiting (Bug#8239).
10893 2011-05-28 Jim Meyering <meyering@redhat.com>
10895 Avoid a sign-extension bug in crypto_hash_function.
10896 * fns.c (to_uchar): Define.
10897 (crypto_hash_function): Use it to convert some newly-signed
10898 variables to unsigned, to avoid sign-extension bugs. For example,
10899 without this change, (md5 "truc") would evaluate to
10900 45723a2aff78ff4fff7fff1114760e62 rather than the expected
10901 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
10902 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
10904 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
10906 Integer overflow fixes.
10908 * dbusbind.c: Serial number integer overflow fixes.
10909 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
10910 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
10911 to hold a serial number that is too large for a fixnum.
10912 (Fdbus_method_return_internal, Fdbus_method_error_internal):
10913 Check for serial numbers out of range. Decode any serial number
10914 that was so large that it became a float. (Bug#8722)
10916 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
10917 (Fdbus_call_method, Fdbus_call_method_asynchronously):
10918 Use XFASTINT rather than XUINT when numbers are nonnegative.
10919 (xd_append_arg, Fdbus_method_return_internal):
10920 (Fdbus_method_error_internal): Likewise. Also, for unsigned
10921 arguments, check that Lisp number is nonnegative, rather than
10922 silently wrapping negative numbers around. (Bug#8722)
10923 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
10924 (Bug#8722)
10926 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
10928 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
10930 ccl: Add integer overflow checks.
10931 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
10932 (IN_INT_RANGE): New macros.
10933 (ccl_driver): Use them to check for integer overflow when
10934 decoding a CCL program. Many of the new checks are whether XINT (x)
10935 fits in int; it doesn't always, on 64-bit hosts. The new version
10936 doesn't catch all possible integer overflows, but it's an
10937 improvement. (Bug#8719)
10939 * alloc.c (make_event_array): Use XINT, not XUINT.
10940 There's no need for unsigned here.
10942 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
10943 This follows up to the 2011-05-06 change that substituted uintptr_t
10944 for EMACS_INT. This case wasn't caught back then.
10946 Rework Fformat to avoid integer overflow issues.
10947 * editfns.c: Include <float.h> unconditionally, as it's everywhere
10948 now (part of C89). Include <verify.h>.
10949 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
10950 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
10951 (Fformat): Avoid the prepass trying to compute sizes; it was only
10952 approximate and thus did not catch overflow reliably. Instead, walk
10953 through the format just once, formatting and computing sizes as we go,
10954 checking for integer overflow at every step, and allocating a larger
10955 buffer as needed. Keep track separately whether the format is
10956 multibyte. Keep only the most-recently calculated precision, rather
10957 than them all. Record whether each argument has been converted to
10958 string. Use EMACS_INT, not int, for byte and char and arg counts.
10959 Support field widths and precisions larger than INT_MAX. Avoid
10960 sprintf's undefined behavior with conversion specifications such as %#d
10961 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
10962 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
10963 formatting out-of-range floating point numbers with int
10964 formats. (Bug#8668)
10966 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
10968 * data.c: Avoid integer truncation in expressions involving floats.
10969 * data.c: Include <intprops.h>.
10970 (arith_driver): When there's an integer overflow in an expression
10971 involving floating point, convert the integers to floating point
10972 so that the resulting value does not suffer from catastrophic
10973 integer truncation. For example, on a 64-bit host (* 4
10974 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
10975 Do not rely on undefined behavior after integer overflow.
10977 merge count_size_as_multibyte, parse_str_to_multibyte
10978 * character.c, character.h (count_size_as_multibyte):
10979 Rename from parse_str_to_multibyte; all uses changed.
10980 Check for integer overflow.
10981 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
10982 since it's now a duplicate of the other. This is more of
10983 a character than a buffer op, so better that it's in character.c.
10984 * fns.c, print.c: Adjust to above changes.
10986 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
10988 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
10990 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
10992 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
10993 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
10994 (x_clipboard_manager_save): Now static.
10995 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
10997 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
10998 (crypto_hash_function): Now static.
10999 Fix pointer signedness problems. Avoid unnecessary initializations.
11001 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
11003 * termhooks.h (Vselection_alist): Make it terminal-local.
11005 * terminal.c (create_terminal): Initialize it.
11007 * xselect.c: Support for clipboard managers.
11008 (Vselection_alist): Move to termhooks.h as terminal-local var.
11009 (LOCAL_SELECTION): New macro.
11010 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
11011 (symbol_to_x_atom): Remove gratuitous arg.
11012 (x_handle_selection_request, lisp_data_to_selection_data)
11013 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
11014 (x_own_selection, x_get_local_selection, x_convert_selection):
11015 New arg, specifying work frame. Use terminal-local Vselection_alist.
11016 (some_frame_on_display): Delete unused function.
11017 (Fx_own_selection_internal, Fx_get_selection_internal)
11018 (Fx_disown_selection_internal, Fx_selection_owner_p)
11019 (Fx_selection_exists_p): New optional frame arg.
11020 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
11021 (x_handle_selection_clear): Don't treat other terminals with the
11022 same keyboard specially. Use the terminal-local Vselection_alist.
11023 (x_clear_frame_selections): Use Frun_hook_with_args.
11025 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
11027 * xterm.h: Add support for those atoms.
11029 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
11031 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
11032 (converted_selections, conversion_fail_tag): New global variables.
11033 (x_selection_request_lisp_error): Free the above.
11034 (x_get_local_selection): Remove unnecessary code.
11035 (x_reply_selection_request): Args changed; handle arbitrary array
11036 of converted selections stored in converted_selections.
11037 Separate the XChangeProperty and SelectionNotify steps.
11038 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
11039 (x_convert_selection): New function.
11040 (x_handle_selection_event): Simplify.
11041 (x_get_foreign_selection): Don't ignore incoming requests while
11042 waiting for an answer; this will fail when we implement
11043 SAVE_TARGETS, and seems unnecessary anyway.
11044 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
11045 (Vx_sent_selection_functions): Doc fix.
11047 2011-05-26 Leo Liu <sdl.web@gmail.com>
11049 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
11051 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11053 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
11055 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
11056 for fringe update if it has periodic bitmap.
11057 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
11058 and fringe_bitmap_periodic_p.
11060 * fringe.c (get_fringe_bitmap_data): New function.
11061 (draw_fringe_bitmap_1, update_window_fringes): Use it.
11062 (update_window_fringes): Record periodicity of fringe bitmap in glyph
11063 row. Mark glyph row for fringe update if periodicity changed.
11065 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
11066 for fringe update unless it has periodic bitmap.
11068 2011-05-25 Kenichi Handa <handa@m17n.org>
11070 * xdisp.c (get_next_display_element): Set correct it->face_id for
11071 a static composition.
11073 2011-05-24 Leo Liu <sdl.web@gmail.com>
11075 * deps.mk (fns.o):
11076 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
11078 * fns.c (crypto_hash_function, Fsha1): New function.
11079 (Fmd5): Use crypto_hash_function.
11080 (syms_of_fns): Add Ssha1.
11082 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
11084 * gnutls.c: Remove unused macros.
11085 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
11086 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
11087 Remove macros that are defined and never used.
11088 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
11090 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
11092 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
11093 (Fx_get_selection_internal): Minor cleanup.
11094 (Fx_own_selection_internal): Rename arguments for consistency with
11095 select.el.
11097 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
11099 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
11101 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
11103 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
11105 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11107 * dispnew.c (scrolling_window): Don't exclude the case that the
11108 last enabled row in the desired matrix touches the bottom boundary.
11110 2011-05-21 Glenn Morris <rgm@gnu.org>
11112 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
11113 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
11114 and add some more files.
11116 2011-05-20 Eli Zaretskii <eliz@gnu.org>
11118 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
11119 report_file_error introduced by the change from 2011-05-07.
11121 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
11123 * systime.h (Time): Define only if emacs is defined.
11124 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
11125 where the include path doesn't have X11/X.h by default. See
11126 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
11128 2011-05-20 Kenichi Handa <handa@m17n.org>
11130 * composite.c (find_automatic_composition): Fix previous change.
11132 2011-05-20 Glenn Morris <rgm@gnu.org>
11134 * lisp.mk: New file, split from Makefile.in.
11135 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
11136 (shortlisp): Remove.
11137 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
11139 2011-05-19 Glenn Morris <rgm@gnu.org>
11141 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
11142 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
11143 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
11144 (lisp): Set the order to that of loadup.el.
11145 (shortlisp): Make it a copy of $lisp.
11146 (SOME_MACHINE_LISP): Remove.
11147 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
11148 Use just $shortlisp, not $SOME_MACHINE_LISP too.
11150 2011-05-18 Kenichi Handa <handa@m17n.org>
11152 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
11153 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
11154 (find_automatic_composition): Mostly rewrite for efficiency.
11156 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
11158 * makefile.w32-in: Update dependencies.
11160 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
11162 * menu.c: Include limits.h (fixes the MS-Windows build broken by
11163 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
11165 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
11167 Fix some integer overflow issues, such as string length overflow.
11169 * insdel.c (count_size_as_multibyte): Check for string overflow.
11171 * character.c (lisp_string_width): Check for string overflow.
11172 Use EMACS_INT, not int, for string indexes and lengths; in
11173 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
11174 the resulting string length overflows an EMACS_INT; instead,
11175 report a string overflow if no precision given. When checking for
11176 precision exhaustion, use a check that cannot possibly have
11177 integer overflow. (Bug#8675)
11178 * character.h (lisp_string_width): Adjust to new signature.
11180 * alloc.c (string_overflow): New function.
11181 (Fmake_string): Use it. This doesn't change behavior, but saves
11182 a few bytes and will simplify future changes.
11183 * character.c (string_escape_byte8): Likewise.
11184 * lisp.h (string_overflow): New decl.
11186 Fixups, following up to the user-interface timestamp change.
11187 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
11188 for UI timestamps, instead of unsigned long.
11189 * msdos.c (mouse_get_pos): Likewise.
11190 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
11191 * w32gui.h (Time): Define by including "systime.h" rather than by
11192 declaring it ourselves. (Bug#8664)
11194 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
11195 * image.c (clear_image_cache): Likewise.
11197 * term.c (term_mouse_position): Don't assume time_t wraparound.
11199 Be more systematic about user-interface timestamps.
11200 Before, the code sometimes used 'Time', sometimes 'unsigned long',
11201 and sometimes 'EMACS_UINT', to represent these timestamps.
11202 This change causes it to use 'Time' uniformly, as that's what X uses.
11203 This makes the code easier to follow, and makes it easier to catch
11204 integer overflow bugs such as Bug#8664.
11205 * frame.c (Fmouse_position, Fmouse_pixel_position):
11206 Use Time, not unsigned long, for user-interface timestamps.
11207 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
11208 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
11209 * keyboard.h (last_event_timestamp): Likewise.
11210 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
11211 * menu.h (xmenu_show): Likewise.
11212 * term.c (term_mouse_position): Likewise.
11213 * termhooks.h (struct input_event.timestamp): Likewise.
11214 (struct terminal.mouse_position_hook): Likewise.
11215 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
11216 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
11217 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
11218 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
11219 what it was before.
11220 * menu.h, termhooks.h: Include "systime.h", for Time.
11222 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
11223 Don't assume that the difference between two unsigned long values
11224 can fit into an integer. At this point, we know button_down_time
11225 <= event->timestamp, so the difference must be nonnegative, so
11226 there's no need to cast the result if double-click-time is
11227 nonnegative, as it should be; check that it's nonnegative, just in
11228 case. This bug is triggered when events are more than 2**31 ms
11229 apart (about 25 days). (Bug#8664)
11231 * xselect.c (last_event_timestamp): Remove duplicate decl.
11232 (x_own_selection): Remove needless cast to unsigned long.
11234 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
11235 that always fit in int. Use a sentinel instead of a counter, to
11236 avoid a temp and to allay GCC's concerns about possible int overflow.
11237 * frame.h (struct frame): Use int for menu_bar_items_used
11238 instead of EMACS_INT, since it always fits in int.
11240 * menu.c (grow_menu_items): Check for int overflow.
11242 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
11244 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
11245 Before, the code was not consistent. These values cannot exceed
11246 2**31 - 1 so there's no need to make them unsigned.
11247 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
11248 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
11249 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
11250 as modifiers.
11251 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
11253 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
11254 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
11255 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
11256 presumably because the widths might not match.
11258 * window.c (size_window): Avoid needless test at loop start.
11260 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
11262 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
11264 2011-05-12 Drew Adams <drew.adams@oracle.com>
11266 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
11268 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11270 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
11271 `width' to `bar_area_x' and `bar_area_width', respectively.
11272 (x_scroll_run): Take account of fringe background extension.
11274 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
11275 Rename local vars `left' and `width' to `bar_area_x' and
11276 `bar_area_width', respectively.
11277 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
11278 background extension.
11280 2011-05-10 Jim Meyering <meyering@redhat.com>
11282 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
11284 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
11286 * image.c (Finit_image_library): Return t for built-in image types,
11287 like pbm and xbm. (Bug#8640)
11289 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
11291 * w32menu.c (set_frame_menubar): Fix submenu allocation.
11293 2011-05-07 Eli Zaretskii <eliz@gnu.org>
11295 * w32console.c (Fset_screen_color): Doc fix.
11296 (Fget_screen_color): New function.
11297 (syms_of_ntterm): Defsubr it.
11299 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
11300 unlink the temporary file if Fcall_process didn't create it in the
11301 first place.
11302 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
11303 child process will be redirected to a file specified with `:file'.
11304 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
11305 cue to call_process_cleanup not to close that handle.
11307 2011-05-07 Ben Key <bkey76@gmail.com>
11309 * makefile.w32-in: The bootstrap-temacs rule now makes use of
11310 one of two shell specific rules, either bootstrap-temacs-CMD or
11311 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
11312 to the previous implementation of the bootstrap-temacs rule.
11313 The bootstrap-temacs-CMD rule is similar to the previous
11314 implementation of the bootstrap-temacs rule except that it
11315 makes use of the ESC_CFLAGS variable instead of the CFLAGS
11316 variable.
11318 These changes, along with some changes to nt/configure.bat,
11319 nt/gmake.defs, and nt/nmake.defs, are required to extend my
11320 earlier fix to add support for --cflags and --ldflags options
11321 that include quotes so that it works whether make uses cmd or
11322 sh as the shell.
11324 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
11326 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
11327 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
11328 is a constant.
11329 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
11330 a string. Handle both cases.
11331 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
11332 (Fdbus_register_method): Use Qinvalid_function.
11334 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
11336 * makefile.w32-in: Update dependencies.
11337 (LISP_H): Add inttypes.h and stdin.h.
11338 (PROCESS_H): Add unistd.h.
11340 2011-05-06 Eli Zaretskii <eliz@gnu.org>
11342 * lread.c: Include limits.h (fixes the MS-Windows build broken by
11343 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
11345 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
11347 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
11349 * term.c (vfatal): Remove stray call to va_end.
11350 It's not needed and the C Standard doesn't allow it here anyway.
11352 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
11353 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
11355 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
11356 bytes.
11358 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
11360 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
11362 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
11364 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
11366 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
11368 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
11369 * charset.c (Fdefine_charset_internal): Don't initialize
11370 charset.code_space[15]. The value was garbage, on hosts with
11371 32-bit int (Bug#8600).
11373 * lread.c (read_integer): Be more consistent with string-to-number.
11374 Use string_to_number to do the actual conversion; this avoids
11375 rounding errors and fixes some other screwups. Without this fix,
11376 for example, #x1fffffffffffffff was misread as -2305843009213693952.
11377 (digit_to_number): Move earlier, for benefit of read_integer.
11378 Return -1 if the digit is out of range for the base, -2 if it is
11379 not a digit in any supported base. (Bug#8602)
11381 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
11383 * dispnew.c (scrolling_window): Return 1 if we scrolled,
11384 to match comment at start of function. This also removes a
11385 GCC warning about overflow in a 32+64-bit port.
11387 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
11389 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
11390 Reported by Stefan Monnier in
11391 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
11392 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
11393 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
11395 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
11396 (EMACS_UINTPTR): Likewise, with uintptr_t.
11398 * lisp.h: Prefer 64-bit EMACS_INT if available.
11399 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
11400 on 32-bit hosts that have 64-bit int, so that they can access
11401 large files.
11402 However, temporarily disable this change unless the temporary
11403 symbol WIDE_EMACS_INT is defined.
11405 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
11407 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
11408 This removes an assumption that EMACS_INT and long are the same
11409 width as pointers. The assumption is true for Emacs porting targets
11410 now, but we want to make other targets possible.
11411 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
11412 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
11413 In the rest of the code, change types of integers that hold casted
11414 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
11415 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
11416 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
11417 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
11418 No need to cast type when ORing.
11419 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
11420 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
11421 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
11422 assume EMACS_INT is the same width as char *.
11423 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
11424 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
11425 Remove no-longer-needed casts.
11426 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
11427 (xg_tool_bar_help_callback, xg_make_tool_item):
11428 Use EMACS_INTPTR to hold an integer
11429 that will be cast to void *; this can avoid a GCC warning
11430 if EMACS_INT is not the same width as void *.
11431 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
11432 * xdisp.c (display_echo_area_1, resize_mini_window_1):
11433 (current_message_1, set_message_1):
11434 Use a local to convert to proper width without a cast.
11435 * xmenu.c (dialog_selection_callback): Likewise.
11437 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
11438 Also, don't assume VALBITS / RAND_BITS is less than 5,
11439 and don't rely on undefined behavior when shifting a 1 left into
11440 the sign bit.
11441 * lisp.h (get_random): Change signature to match.
11443 * lread.c (hash_string): Use size_t, not int, for hash computation.
11444 Normally we prefer signed values; but hashing is special, because
11445 it's better to use unsigned division on hash table sizes so that
11446 the remainder is nonnegative. Also, size_t is the natural width
11447 for hashing into memory. The previous code used 'int', which doesn't
11448 retain enough info to hash well into very large tables.
11449 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
11451 * dbusbind.c: Don't possibly lose pointer info when converting.
11452 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
11453 Use XPNTR rather than XHASH, so that the high-order bits of
11454 the pointer aren't lost when converting through void *.
11456 * eval.c (Fautoload): Don't double-shift a pointer.
11458 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
11460 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
11462 * gnutls.c (DEF_GNUTLS_FN):
11463 * image.c (DEF_IMGLIB_FN): Make function pointers static.
11465 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
11467 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
11468 marker. (Bug#8610)
11470 2011-05-05 Eli Zaretskii <eliz@gnu.org>
11472 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
11473 New version that can reserve upto 2GB of heap space.
11475 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
11477 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
11479 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
11481 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
11482 `gnutls_certificate_set_x509_key_file'.
11484 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
11486 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
11487 Update dependencies.
11489 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
11491 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
11492 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
11493 Remove unused parameter `fildes'.
11494 * process.c (read_process_output, send_process): Don't pass it.
11496 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
11498 Fix previous change: the library cache is defined in w32.c.
11499 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
11500 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
11502 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
11504 Implement dynamic loading of GnuTLS on Windows.
11506 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
11507 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
11508 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
11509 Declare.
11511 * gnutls.c (Qgnutls_dll): Define.

11541 * process.c: Include lisp.h before w32.h, not after.
11542 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
11543 instead of gnutls_record_check_pending.
11545 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
11547 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
11549 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
11550 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
11551 as passed in.
11553 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
11555 * xterm.c (x_set_frame_alpha): Do not set property on anything
11556 else than FRAME_X_OUTER_WINDOW (Bug#8608).

11560 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
11562 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
11564 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
11565 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

11586 interruptions.
11588 * callproc.c (Fcall_process): Add (:file "file") as an option for
11589 the STDOUT buffer.
11590 (Fcall_process_region): Ditto.
11592 2011-04-30 Eli Zaretskii <eliz@gnu.org>
11594 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
11595 rather than `XVECTOR (FOO)->size'.
11597 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
11598 inttypes.h, as a gnulib replacement is used if it not available in
11599 system headers.
11601 2011-04-21 Eli Zaretskii <eliz@gnu.org>
11603 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
11604 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
11605 of MOST_POSITIVE_FIXNUM. (Bug#8528)
11607 * coding.c (coding_alloc_by_realloc): Error out if destination
11608 will grow beyond MOST_POSITIVE_FIXNUM.
11609 (decode_coding_emacs_mule): Abort if there isn't enough place in
11610 charbuf for the composition carryover bytes. Reserve an extra
11611 space for up to 2 characters produced in a loop.
11612 (decode_coding_iso_2022): Abort if there isn't enough place in
11613 charbuf for the composition carryover bytes.
11615 2011-04-21 Eli Zaretskii <eliz@gnu.org>
11617 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
11618 aborting when %lld or %lll format is passed.
11619 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
11620 %llo or %llx format is passed. (Bug#8545)
11622 * window.c (window_scroll_line_based): Use a marker instead of
11623 simple variables to record original value of point. (Bug#7952)
11625 * doprnt.c (doprnt): Fix the case where a multibyte sequence
11626 produced by %s or %c overflows available buffer space. (Bug#8545)
11628 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
11630 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
11631 (SIZE_MAX): Move defn after all includes, as they might #define it.
11633 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
11635 * w32.c (init_environment): Warn about defaulting HOME to C:\.
11637 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
11639 * keyboard.c (Qdelayed_warnings_hook): Define.
11640 (command_loop_1): Run `delayed-warnings-hook'
11641 if Vdelayed_warnings_list is non-nil.
11642 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
11643 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
11645 2011-04-28 Eli Zaretskii <eliz@gnu.org>
11647 * doprnt.c (doprnt): Don't return value smaller than the buffer
11648 size if the message was truncated. (Bug#8545).
11650 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
11652 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
11653 (Fx_window_property): #if-0 the whole functions, not just the bodies.
11655 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
11657 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
11659 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
11661 * makefile.w32-in: Update dependencies.
11663 2011-04-27 Eli Zaretskii <eliz@gnu.org>
11665 Improve `doprnt' and its usage. (Bug#8545)
11666 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
11667 `format_end'. Remove support for %l as a conversion specifier.
11668 Don't use xrealloc. Improve diagnostics when the %l size modifier
11669 is used. Update the commentary.
11671 * eval.c (verror): Simplify calculation of size_t.
11673 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
11674 messages.
11676 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
11678 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
11679 change.
11681 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
11683 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
11684 This makes this file independent of the recent pseudovector change.
11686 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
11688 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
11690 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
11691 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
11692 Remove unused local.
11693 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
11695 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
11696 GCC 4.6.0 optimizes based on type-based alias analysis.
11697 For example, if b is of type struct buffer * and v of type struct
11698 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
11699 != &v->size, and therefore "v->size = 1; b->size = 2; return
11700 v->size;" must therefore return 1. This assumption is incorrect
11701 for Emacs, since it type-puns struct Lisp_Vector * with many other
11702 types. To fix this problem, this patch adds a new type struct
11703 vectorlike_header that documents the constraints on layout of vectors
11704 and pseudovectors, and helps optimizing compilers not get fooled
11705 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
11706 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
11707 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
11708 the size member.
11709 (XSETPVECTYPE): Rewrite in terms of new macro.
11710 (XSETPVECTYPESIZE): New macro, specifying both type and size.
11711 This is a bit clearer, and further avoids the possibility of
11712 undesirable aliasing.
11713 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
11714 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
11715 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
11716 since Lisp_Subr is a special case (no "next" field).
11717 (ASIZE): Now uses header.size rather than size.
11718 All previous uses of XVECTOR (foo)->size replaced to use this macro,
11719 to avoid the hassle of writing XVECTOR (foo)->header.size.
11720 (struct vectorlike_header): New type.
11721 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
11722 object, to help avoid aliasing.
11723 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
11724 (SUBRP): Likewise, since Lisp_Subr is a special case.
11725 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
11726 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
11727 (struct Lisp_Hash_Table): Combine first two members into a single
11728 struct vectorlike_header member. All uses of "size" and "next" members
11729 changed to be "header.size" and "header.next".
11730 * buffer.h (struct buffer): Likewise.
11731 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
11732 * frame.h (struct frame): Likewise.
11733 * process.h (struct Lisp_Process): Likewise.
11734 * termhooks.h (struct terminal): Likewise.
11735 * window.c (struct save_window_data, struct saved_window): Likewise.
11736 * window.h (struct window): Likewise.
11737 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
11738 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
11739 * buffer.c (init_buffer_once): Likewise.
11740 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
11741 special case.
11742 * process.c (Fformat_network_address): Use local var for size,
11743 for brevity.
11745 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
11747 Make the Lisp reader and string-to-float more consistent (Bug#8525)
11748 * data.c (atof): Remove decl; no longer used or needed.
11749 (digit_to_number): Move to lread.c.
11750 (Fstring_to_number): Use new string_to_number function, to be
11751 consistent with how the Lisp reader treats infinities and NaNs.
11752 Do not assume that floating-point numbers represent EMACS_INT
11753 without losing information; this is not true on most 64-bit hosts.
11754 Avoid double-rounding errors, by insisting on integers when
11755 parsing non-base-10 numbers, as the documentation specifies.
11756 * lisp.h (string_to_number): New decl, replacing ...
11757 (isfloat_string): Remove.
11758 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
11759 (read1): Do not accept +. and -. as integers; this
11760 appears to have been a coding error. Similarly, do not accept
11761 strings like +-1e0 as floating point numbers. Do not report
11762 overflow for integer overflows unless the base is not 10 which
11763 means we have no simple and reliable way to continue.
11764 Break out the floating-point parsing into a new
11765 function string_to_number, so that Fstring_to_number parses
11766 floating point numbers consistently with the Lisp reader.
11767 (digit_to_number): Move here from data.c. Make it static inline.
11768 (E_CHAR, EXP_INT): Remove, replacing with ...
11769 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
11770 (string_to_number): New function, replacing isfloat_string.
11771 This function checks for valid syntax and produces the resulting
11772 Lisp float number too. Rework it so that string-to-number
11773 no longer mishandles examples like "1.0e+". Use strtoumax,
11774 so that overflow for non-base-10 numbers is reported only when
11775 there's no portable and simple way to convert to floating point.
11777 * textprop.c (set_text_properties_1): Rewrite for clarity,
11778 and to avoid GCC warning about integer overflow.
11780 * intervals.h (struct interval): Use EMACS_INT for members
11781 where EMACS_UINT might cause problems. See
11782 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
11783 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
11784 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
11785 All uses changed.
11786 (offset_intervals): Tell GCC not to worry about length overflow
11787 when negating a negative length.
11789 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
11790 (overrun_check_free): Likewise.
11792 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
11793 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
11794 word size.
11796 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
11797 (gnutls_make_error): Rename local to avoid shadowing.
11798 (gnutls_emacs_global_deinit): ifdef out; not used.
11799 (Fgnutls_boot): Use const for pointer to readonly storage.
11800 Comment out unused local. Fix pointer signedness problems.
11802 * lread.c (openp): Don't stuff size_t into an 'int'.
11803 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
11804 about possible signed overflow.
11806 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
11807 (GDK_KEY_g): Don't define if already defined.
11808 (xg_prepare_tooltip): Avoid pointer signedness problem.
11809 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
11811 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
11812 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
11814 * xfns.c (Fx_window_property): Simplify a bit,
11815 to make a bit faster and to avoid GCC 4.6.0 warning.
11816 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
11818 * fns.c (internal_equal): Don't assume size_t fits in int.
11820 * alloc.c (compact_small_strings): Tighten assertion a little.
11822 Replace pEd with more-general pI, and fix some printf arg casts.
11823 * lisp.h (pI): New macro, generalizing old pEd macro to other
11824 conversion specifiers. For example, use "...%"pI"d..." rather
11825 than "...%"pEd"...".
11826 (pEd): Remove. All uses replaced with similar uses of pI.
11827 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
11828 * alloc.c (check_pure_size): Don't overflow by converting size to int.
11829 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
11830 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
11831 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
11832 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
11833 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
11834 64-bit hosts.
11835 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
11836 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
11837 * print.c (safe_debug_print, print_object): Likewise.
11838 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
11839 to int.
11840 Use pI instead of if-then-else-abort. Use %p to avoid casts,
11841 avoiding the 0 flag, which is not portable.
11842 * process.c (Fmake_network_process): Use pI to avoid cast.
11843 * region-cache.c (pp_cache): Likewise.
11844 * xdisp.c (decode_mode_spec): Likewise.
11845 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
11846 behavior on 64-bit hosts with printf arg.
11847 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
11848 (x_stop_queuing_selection_requests): Likewise.
11849 (x_get_window_property): Don't truncate byte count to an 'int'
11850 when tracing.
11852 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
11853 here, since it parses constructs like leading '-' and spaces,
11854 which are not wanted; and it overflows with large numbers.
11855 Instead, simply match F[0-9]+, which is what is wanted anyway.
11857 * alloc.c: Remove unportable assumptions about struct layout.
11858 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
11859 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
11860 (allocate_vectorlike, make_pure_vector): Use the new macros,
11861 plus offsetof, to remove unportable assumptions about struct layout.
11862 These assumptions hold on all porting targets that I know of, but
11863 they are not guaranteed, they're easy to remove, and removing them
11864 makes further changes easier.
11866 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
11867 This doesn't fix a bug but makes the code clearer.
11868 (string_overrun_cookie): Now const. Use initializers that
11869 don't formally overflow signed char, to avoid warnings.
11870 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
11871 can cause Emacs to crash when string overrun checking is enabled.
11872 (allocate_buffer): Don't assume sizeof (struct buffer) is a
11873 multiple of sizeof (EMACS_INT); it need not be, if
11874 alignof(EMACS_INT) < sizeof (EMACS_INT).
11875 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
11877 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
11879 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
11881 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
11883 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
11884 supposed to be handshaking. (Bug#8556)
11885 Reported by Paul Eggert <eggert@cs.ucla.edu>.
11887 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
11889 * lisp.h (Qdebug): List symbol.
11890 * eval.c (Qdebug): Restore global linkage.
11891 * keyboard.c (debug-on-event): New variable.
11892 (handle_user_signal): Break into debugger when debug-on-event
11893 matches the current signal symbol.
11895 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
11897 * alloc.c (check_sblock, check_string_bytes)
11898 (check_string_free_list): Convert to standard C.
11900 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
11902 * w32.c (emacs_gnutls_push): Fix typo.
11904 2011-04-25 Eli Zaretskii <eliz@gnu.org>
11906 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
11907 "cast to pointer from integer of different size".
11909 Improve doprnt and its use in verror. (Bug#8545)
11910 * doprnt.c (doprnt): Document the set of format control sequences
11911 supported by the function. Use SAFE_ALLOCA instead of always
11912 using `alloca'.
11914 * eval.c (verror): Don't limit the buffer size at size_max-1, that
11915 is one byte too soon. Don't use xrealloc; instead xfree and
11916 xmalloc anew.
11918 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
11920 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
11921 callbacks stage.

12649 DEFUN now defines a static function. To make the function external
12650 so that it can be used in other C modules, use the new macro DEFUE.

12728 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
12729 since callers should never pass a negative size.

12734 2011-04-11 Eli Zaretskii <eliz@gnu.org>
12736 * xdisp.c (redisplay_window): Don't try to determine the character
12737 position of the scroll margin if the window start point w->startp
12738 is outside the buffer's accessible region. (Bug#8468)
12740 2011-04-10 Eli Zaretskii <eliz@gnu.org>
12742 Fix write-region and its subroutines for buffers > 2GB.
12743 * fileio.c (a_write, e_write): Modify declaration of arguments and
12744 local variables to support buffers larger than 2GB.
12745 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
12747 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
12748 argument, local variables, and return value.

12754 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
12756 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.

12760 * xdisp.c (vmessage): Use a better test for character truncation.
12762 * charset.c (load_charset_map): <, not <=, for optimization,

12772 * callint.c (Fcall_interactively): <, not <=, for optimization.
12773 (Fcall_interactively): Count the number of arguments produced,
12774 not the number of arguments given. This is simpler and lets GCC
12775 4.6.0 generate slightly better code.
12777 * ftfont.c: Distingish more carefully between FcChar8 and char.
12778 The previous code passed unsigned char * to a functions like
12779 strlen and xstrcasecmp that expect char *, which does not
12780 conform to the C standard.
12781 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
12782 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
12783 char * when the C standard requires it.
12785 * keyboard.c (read_char): Remove unused var.
12787 * eval.c: Port to Windows vsnprintf (Bug#8435).
12788 Include <limits.h>.
12789 (SIZE_MAX): Define if the headers do not.
12790 (verror): Do not give up if vsnprintf returns a negative count.
12791 Instead, grow the buffer. This ports to Windows vsnprintf, which
12792 does not conform to C99. Problem reported by Eli Zaretskii.
12793 Also, simplify the allocation scheme, by avoiding the need for
12794 calling realloc, and removing the ALLOCATED variable.
12796 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
12798 Remove invocations of doprnt, as Emacs now uses vsnprintf.
12799 But keep the doprint source code for now, as we might revamp it
12800 and use it again (Bug#8435).
12801 * lisp.h (doprnt): Remove.
12802 * Makefile.in (base_obj): Remove doprnt.o.
12803 * deps.mk (doprnt.o): Remove.
12805 error: Print 32- and 64-bit integers portably (Bug#8435).
12806 Without this change, on typical 64-bit hosts error ("...%d...", N)
12807 was used to print both 32- and 64-bit integers N, which relied on
12808 undefined behavior.
12809 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
12810 * lisp.h (error, verror): Mark as printf-like functions.
12811 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
12812 Report overflow in size calculations when allocating printf buffer.
12813 Do not truncate output string at its first null byte.
12814 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
12815 Truncate the output at a character boundary, since vsnprintf does not
12816 do that.
12817 * charset.c (check_iso_charset_parameter): Convert internal
12818 character to string before calling 'error', since %c now has the
12819 printf meaning.
12820 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
12821 overflow when computing char to be passed to 'error'. Do not
12822 pass Lisp_Object to 'error'; pass the integer instead.
12823 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
12824 formatted with plain %d.
12826 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
12828 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
12830 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
12832 * xterm.c (x_catch_errors): Remove duplicate declaration.
12834 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
12836 * xdisp.c, lisp.h (message_nolog): Remove; unused.
12838 2011-04-10 Jim Meyering <meyering@redhat.com>
12840 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
12841 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
12842 return ssize_t not "int", and use size_t as the buffer length.
12843 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
12844 * gnutls.h: Update declarations.
12845 * process.c (read_process_output): Use ssize_t, to match.
12846 (send_process): Likewise.
12848 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
12850 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
12852 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
12854 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
12855 Use unsigned char, to match FcChar8 type definition.
12857 * xterm.c (handle_one_xevent):
12858 * xmenu.c (create_and_show_popup_menu):
12859 * xselect.c (x_decline_selection_request)
12860 (x_reply_selection_request): Avoid type-punned deref of X events.
12862 2011-04-09 Eli Zaretskii <eliz@gnu.org>
12864 Fix some uses of `int' instead of EMACS_INT.
12865 * search.c (string_match_1, fast_string_match)
12866 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
12867 (scan_buffer, find_next_newline_no_quit)
12868 (find_before_next_newline, search_command, Freplace_match)
12869 (Fmatch_data): Make some `int' variables be EMACS_INT.
12871 * xdisp.c (display_count_lines): 3rd argument and return value now
12872 EMACS_INT. All callers changed.
12873 (pint2hrstr): Last argument is now EMACS_INT.
12875 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
12876 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
12877 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
12878 (decode_coding_utf_16, decode_coding_emacs_mule)

12884 <char_offset, last_offset>: Declare EMACS_INT.
12885 (encode_coding_utf_8, encode_coding_utf_16)
12886 (encode_coding_emacs_mule, encode_invocation_designation)
12887 (encode_designation_at_bol, encode_coding_iso_2022)
12888 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
12889 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
12890 Declare EMACS_INT.
12891 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
12892 (encode_invocation_designation): Last argument P_NCHARS is now
12893 EMACS_INT.
12894 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
12895 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
12897 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
12898 All users changed.
12900 * ccl.c (Fccl_execute_on_string): Declare some variables
12901 EMACS_INT.
12903 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)

12915 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
12917 * keyboard.c (read_char): Call Lisp function help-form-show,
12918 instead of using internal_with_output_to_temp_buffer.
12919 (Qhelp_form_show): New var.
12920 (syms_of_keyboard): Use DEFSYM macro.
12922 * print.c (internal_with_output_to_temp_buffer): Function deleted.
12924 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
12926 2011-04-06 Chong Yidong <cyd@stupidchicken.com>

12935 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
12937 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
12939 Fix more problems found by GCC 4.6.0's static checks.

12955 (tiff_load): Add casts to remove these marks before passing them
12956 to system-supplied API.
12958 * eval.c (Fsignal): Remove excess argument to 'fatal'.
12960 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
12961 This avoids several warnings with gcc -Wstrict-overflow.
12962 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
12963 directly, rather than having caller test rule sign. This avoids
12964 some unnecessary tests.
12965 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
12966 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
12967 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
12969 * xfont.c (xfont_text_extents): Remove var that was set but not used.
12970 (xfont_open): Avoid unnecessary tests.
12972 * composite.c (composition_gstring_put_cache): Use unsigned integer.
12974 * composite.h, composite.c (composition_gstring_put_cache):
12975 Use EMACS_INT, not int, for length.
12977 * composite.h (COMPOSITION_DECODE_REFS): New macro,
12978 breaking out part of COMPOSITION_DECODE_RULE.
12979 (COMPOSITION_DECODE_RULE): Use it.
12980 * composite.c (get_composition_id): Remove unused local vars,
12981 by using the new macro.
12983 * textprop.c (set_text_properties_1): Change while to do-while,
12984 since the condition is always true at first.
12986 * intervals.c (graft_intervals_into_buffer): Mark var as used.
12987 (interval_deletion_adjustment): Return unsigned value.
12988 All uses changed.

12991 (exec_sentinel): Remove vars that were set but not used.
12992 (create_pty): Remove unnecessary "volatile"s.

13004 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
13006 * print.c (print_error_message): Avoid int overflow.
13008 * font.c (font_list_entities): Redo for clarity,
13009 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
13011 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
13012 (font_score): Avoid potential overflow in diff calculation.
13014 * fns.c (substring_both): Remove var that is set but not used.
13015 (sxhash): Redo loop for clarity and to avoid wraparound warning.
13017 * eval.c (funcall_lambda): Rename local to avoid shadowing.
13019 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
13020 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
13021 can always succeed if overflow has undefined behavior.
13023 * search.c (boyer_moore, wordify): Remove vars set but not used.
13024 (wordify): Omit three unnecessary tests.
13026 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
13027 All callers changed. This avoids the need for an unused var.

13031 * dired.c (file_name_completion): Remove var that is set but not used.
13033 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
13035 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
13036 (Finsert_file_contents): Remove unnecessary code checking fd.
13038 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
13039 Check for integer overflow on size calculations.
13041 * buffer.c (Fprevious_overlay_change): Remove var that is set
13042 but not used.
13044 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
13045 Remove vars that are set but not used.
13046 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
13047 (timer_check_2): Mark vars as initialized.
13049 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
13051 * image.c (lookup_image): Remove var that is set but not used.
13052 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
13054 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
13055 that are set but not used.
13057 * xfns.c (make_invisible_cursor): Don't return garbage
13058 if XCreateBitmapFromData fails (Bug#8410).
13060 * xselect.c (x_get_local_selection, x_handle_property_notify):
13061 Remove vars that are set but not used.
13063 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
13064 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
13066 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
13067 Remove var that is set but not used.
13068 (scroll_bar_windows_size): Now size_t, not int.
13069 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
13070 Check for overflow.
13072 * xfaces.c (realize_named_face): Remove vars that are set but not used.
13073 (map_tty_color) [!defined MSDOS]: Likewise.
13075 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
13077 * coding.c: Remove vars that are set but not used.
13078 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
13079 All callers changed.
13080 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
13081 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
13082 (decode_coding_charset): Remove vars that are set but not used.
13084 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
13085 that is set but not used.
13087 * print.c (print_object): Remove var that is set but not used.
13089 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
13090 The gnulib version avoids calling malloc in the usual case,
13091 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
13092 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
13093 * filelock.c (current_lock_owner): Likewise.
13094 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
13095 * sysdep.c: Include allocator.h, careadlinkat.h.
13096 (emacs_no_realloc_allocator): New static constant.
13097 (emacs_readlink): New function.
13098 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
13099 ../lib/careadlinkat.h.
13101 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
13103 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
13104 first non-nil return value).
13106 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
13108 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
13109 if not defined (Bug#8403).
13111 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
13113 * xdisp.c (display_count_lines): Remove parameter `start',

13118 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
13119 and thereabouts. All callers changed.
13120 (get_per_char_metric): Remove parameter `f', unused since
13121 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
13123 2011-04-02 Jim Meyering <meyering@redhat.com>
13125 do not dereference NULL upon failed strdup
13126 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
13127 (ns_get_family): Likewise.
13129 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
13131 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
13133 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
13135 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
13136 later (Bug#8403).
13138 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
13140 Add lexical binding.
13142 * window.c (Ftemp_output_buffer_show): New fun.
13143 (Fsave_window_excursion):
13144 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
13146 * lread.c (lisp_file_lexically_bound_p): New function.

13151 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
13152 Mark as dynamic.
13153 (syms_of_lread): Declare `lexical-binding'.
13155 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
13157 * keyboard.c (eval_dyn): New fun.
13158 (menu_item_eval_property): Use it.
13160 * image.c (parse_image_spec): Use Ffunctionp.
13162 * fns.c (concat, mapcar1): Accept byte-code-functions.
13164 * eval.c (Fsetq): Handle lexical vars.
13165 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
13166 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
13167 (FletX, Flet): Obey lexical binding.
13168 (Fcommandp): Handle closures.
13169 (Feval): New `lexical' arg.
13170 (eval_sub): New function extracted from Feval. Use it almost
13171 everywhere where Feval was used. Look up vars in lexical env.
13172 Handle closures.
13173 (Ffunctionp): Move from subr.el.
13174 (Ffuncall): Handle closures.
13175 (apply_lambda): Remove `eval_flags'.
13176 (funcall_lambda): Handle closures and new byte-code-functions.
13177 (Fspecial_variable_p): New function.
13178 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
13179 but without exporting it to Lisp.
13181 * doc.c (Fdocumentation, store_function_docstring):
13182 * data.c (Finteractive_form): Handle closures.
13184 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
13185 interactive spec.
13187 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
13188 New byte-codes.
13189 (exec_byte_code): New function extracted from Fbyte_code to handle new
13190 calling convention for byte-code-functions. Add new byte-codes.
13192 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
13194 * alloc.c (Fmake_symbol): Init new `declared_special' field.
13196 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
13198 * xdisp.c (redisplay_internal): Fix prototype.
13200 2011-03-31 Eli Zaretskii <eliz@gnu.org>
13202 * xdisp.c (SCROLL_LIMIT): New macro.
13203 (try_scrolling): Use it when setting scroll_limit.
13204 Limit scrolling to 100 screen lines.
13205 (redisplay_window): Even when falling back on "recentering",
13206 position point in the window according to scroll-conservatively,
13207 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
13209 (try_scrolling): When point is above the window, allow searching
13210 as far as scroll_max, or one screenful, to compute vertical
13211 distance from PT to the scroll margin position. This prevents
13212 try_scrolling from unnecessarily failing when
13213 scroll-conservatively is set to a value slightly larger than the
13214 window height. Clean up the case of PT below the margin at bottom
13215 of window: scroll_max can no longer be INT_MAX. When aggressive
13216 scrolling is in use, don't let point enter the opposite scroll
13217 margin as result of the scroll.
13218 (syms_of_xdisp) <scroll-conservatively>: Document the
13219 threshold of 100 lines for never-recentering scrolling.
13221 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
13223 * dispextern.h (move_it_by_lines):
13224 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
13225 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
13226 (message_log_check_duplicate): Remove parameters `prev_bol' and
13227 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
13228 (redisplay_internal): Remove parameter `preserve_echo_area',
13229 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
13231 * indent.c (Fvertical_motion):
13232 * window.c (window_scroll_pixel_based, Frecenter):
13233 Don't pass `need_y_p' to `move_it_by_lines'.
13235 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
13237 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
13238 steal a few bits to be more compact.
13239 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
13240 Remove unneeded casts.
13242 * bytecode.c (Fbyte_code): CAR and CDR can GC.
13244 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
13246 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
13247 binding" message (bug#7967).
13249 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
13251 Fix more problems found by GCC 4.6.0's static checks.
13253 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
13254 Remove unused local var.
13256 * editfns.c (Fmessage_box): Remove unused local var.
13258 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
13259 (note_mode_line_or_margin_highlight, note_mouse_highlight):
13260 Omit unused local vars.
13261 * window.c (shrink_windows): Omit unused local var.
13262 * menu.c (digest_single_submenu): Omit unused local var.
13263 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
13264 Omit unused local var.
13266 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
13267 Don't assume string length fits in int.
13268 (keyremap_step, read_key_sequence): Use size_t for sizes.
13269 (read_key_sequence): Don't check last_real_key_start redundantly.
13271 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
13272 instead of alloca (Bug#8344).
13274 * eval.c (Fbacktrace): Don't assume nargs fits in int.
13275 (Fbacktrace_frame): Don't assume nframes fits in int.
13277 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

13284 * cm.c (calccost): Turn while-do into do-while, for clarity.
13286 * keyboard.c (syms_of_keyboard): Use the same style as later
13287 in this function when indexing through an array. This also
13288 works around GCC bug 48267.
13290 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
13292 * xselect.c (x_check_property_data): Return correct size (Bug#8335).

13295 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
13297 * keyboard.c, keyboard.h (num_input_events): Now size_t.
13298 This avoids undefined behavior on integer overflow, and is a bit
13299 more convenient anyway since it is compared to a size_t variable.
13301 Variadic C functions now count arguments with size_t, not int.
13302 This avoids an unnecessary limitation on 64-bit machines, which
13303 caused (substring ...) to crash on large vectors (Bug#8344).
13304 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
13305 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
13306 All variadic functions and their callers changed accordingly.
13307 (struct gcpro.nvars): Now size_t, not int. All uses changed.

13311 (internal_condition_case_n, run_hook_with_args, apply_lambda)
13312 (funcall_lambda, mark_backtrace): Likewise.
13313 * fns.c (concat): Likewise.
13314 * frame.c (x_set_frame_parameters): Likewise.
13315 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
13316 0 if not found, not -1. All callers changed.
13318 * alloc.c (garbage_collect): Don't assume stack size fits in int.
13319 (stack_copy_size): Now size_t, not int.
13320 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
13322 2011-03-28 Juanma Barranquero <lekktu@gmail.com>

13325 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
13326 All callers changed.
13328 * lisp.h (multibyte_char_to_unibyte):
13329 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
13330 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
13331 * character.h (CHAR_TO_BYTE8):
13332 * cmds.c (internal_self_insert):
13333 * editfns.c (general_insert_function):
13334 * keymap.c (push_key_description):
13335 * search.c (Freplace_match):
13336 * xdisp.c (message_dolog, set_message_1): All callers changed.
13338 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
13340 * keyboard.c (safe_run_hook_funcall): New function.
13341 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
13342 don't set the hook to nil, but remove the offending function instead.
13343 (Qcommand_hook_internal): Remove, unused.
13344 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
13345 Vcommand_hook_internal.
13347 * eval.c (enum run_hooks_condition): Remove.
13348 (funcall_nil, funcall_not): New functions.
13349 (run_hook_with_args): Call each function through a `funcall' argument.
13350 Remove `cond' argument, now redundant.
13351 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
13352 (Frun_hook_with_args_until_failure): Adjust accordingly.
13353 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.

13359 * print.c (strout): Remove parameter `multibyte', unused since
13360 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
13362 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
13363 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
13364 All callers changed.
13366 * w32.c (_wsa_errlist): Use braces for struct initializers.

13372 used outside xdisp.c).
13373 (cursor_row_p): Remove parameter `w', unused since
13374 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

13376 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
13377 All callers changed.
13379 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
13381 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.

13410 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
13412 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
13414 * w32.c (read_unc_volume): Use parameter `henum', instead of
13415 global variable `wget_enum_handle'.
13417 * keymap.c (describe_vector): Remove parameters `indices' and
13418 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.

13433 * gtkutil.c (xg_maybe_add_timer):
13434 * keyboard.c (readable_events):
13435 * process.c (wait_reading_process_output):
13436 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
13438 * insdel.c (adjust_markers_gap_motion):
13439 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.

13513 2011-03-23 Julien Danjou <julien@danjou.info>
13515 * term.c (Fsuspend_tty, Fresume_tty):
13516 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
13517 * window.c (temp_output_buffer_show):
13518 * insdel.c (signal_before_change):
13519 * frame.c (Fhandle_switch_frame):
13520 * fileio.c (Fdo_auto_save):
13521 * emacs.c (Fkill_emacs):
13522 * editfns.c (save_excursion_restore):
13523 * cmds.c (internal_self_insert):
13524 * callint.c (Fcall_interactively):
13525 * buffer.c (Fkill_all_local_variables):
13526 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
13527 Use Frun_hooks.
13528 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
13529 unconditionally since it does the check itself.
13531 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
13533 Fix more problems found by GCC 4.5.2's static checks.
13535 * coding.c (encode_coding_raw_text): Avoid unnecessary test
13536 the first time through the loop, since we know p0 < p1 then.
13537 This also avoids a gcc -Wstrict-overflow warning.
13539 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
13540 leading to a memory leak, possible in functions like
13541 load_charset_map_from_file that can allocate an unbounded number
13542 of objects (Bug#8318).
13544 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
13545 that could (at least in theory) be that large.
13547 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
13548 This is less likely to overflow, and avoids undefined behavior if
13549 overflow does occur. All callers changed. Use strtoul to scan
13550 for the unsigned long integer.
13551 (pint2hrstr): Simplify and tune code slightly.
13552 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

13555 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
13557 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
13558 This also avoids a warning with gcc -Wstrict-overflow.

13560 This also avoids a warning with gcc -Wstrict-overflow.
13562 * fileio.c (Fcopy_file): Report error if fchown or fchmod
13563 fail (Bug#8306).
13565 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
13567 * process.c (Fmake_network_process): Use socklen_t, not int,
13568 where POSIX says socklen_t is required in portable programs.
13569 This fixes a porting bug on hosts like 64-bit HP-UX, where
13570 socklen_t is wider than int (Bug#8277).
13571 (Fmake_network_process, server_accept_connection):
13572 (wait_reading_process_output, read_process_output):
13573 Likewise.
13575 * process.c: Rename or move locals to avoid shadowing.
13576 (list_processes_1, Fmake_network_process):
13577 (read_process_output_error_handler, exec_sentinel_error_handler):
13578 Rename or move locals.
13579 (Fmake_network_process): Define label "retry_connect" only if needed.
13580 (Fnetwork_interface_info): Fix pointer signedness.
13581 (process_send_signal): Add cast to avoid pointer signedness problem.
13582 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
13583 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
13585 Make tparam.h and terminfo.c consistent.
13586 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
13587 Include tparam.h instead, since it declares them.
13588 * cm.h (PC): Remove extern decl; tparam.h now does this.
13589 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
13590 * terminfo.c: Include tparam.h, to check interfaces.
13591 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
13592 (tparam): Adjust signature to match interface in tparam.h;
13593 this removes some undefined behavior. Check that outstring and len
13594 are zero, which they always are with Emacs.
13595 * tparam.h (PC, BC, UP): New extern decls.
13597 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
13598 (xftfont_open): Rename locals to avoid shadowing.
13600 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
13601 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
13602 (OTF_TAG_SYM): Omit macro if not needed.
13603 (ftfont_list): Remove unused local.
13604 (get_adstyle_property, ftfont_pattern_entity):
13605 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
13606 Rename locals to avoid shadowing.
13608 * xfont.c (xfont_list_family): Mark var as initialized.
13610 * xml.c (make_dom): Now static.
13612 * composite.c (composition_compute_stop_pos): Rename local to
13613 avoid shadowing.
13614 (composition_reseat_it): Remove unused locals.
13615 (find_automatic_composition, composition_adjust_point): Likewise.
13616 (composition_update_it): Mark var as initialized.
13617 (find_automatic_composition): Mark vars as initialized,
13618 with a FIXME (Bug#8290).
13620 character.h: Rename locals to avoid shadowing.
13621 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
13622 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
13623 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
13624 (BUF_DEC_POS): Be more systematic about renaming local temporaries
13625 to avoid shadowing.
13627 * textprop.c (property_change_between_p): Remove; unused.
13629 * intervals.c (interval_start_pos): Now static.
13631 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
13633 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
13634 Rename locals to avoid shadowing.
13636 * sound.c (wav_play, au_play, Fplay_sound_internal):
13637 Fix pointer signedness.
13638 (alsa_choose_format): Remove unused local var.
13639 (wav_play): Initialize a variable to 0, to prevent undefined
13640 behavior (Bug#8278).
13642 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
13644 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
13646 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
13647 clobbering (Bug#8298).
13648 * sysdep.c (sys_subshell): Likewise.
13649 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
13651 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
13652 This should get cleaned up, so that child_setup has the
13653 same signature on all platforms.
13655 * callproc.c (call_process_cleanup): Now static.
13656 (relocate_fd): Rename locals to avoid shadowing.
13658 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
13660 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears

13718 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
13720 * deps.mk (unexalpha.o): Remove; unused.
13722 New file unexec.h, the (simple) interface for unexec (Bug#8267).

13782 Move decls here, to check interfaces.
13783 * process.c (get_operating_system_release): Move decl to lisp.h.
13784 * xrdb.c (get_system_name): Likewise.

13786 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
13787 some of which prompt warnings from gcc -Wbad-function-cast.
13788 (Fformat_time_string, Fencode_time, Finsert_char):
13789 (Ftranslate_region_internal, Fformat):

13817 (Fmemory_limit): Cast sbrk's returned value to char *.

13822 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
13824 Use functions, not macros, for up- and down-casing (Bug#8254).
13825 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
13826 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
13827 to use the following functions instead of these macros.
13828 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
13829 EMACS_INT, since callers assume the returned value fits in int.
13830 (upcase1): Likewise, for UPCASE_TABLE.
13831 (uppercasep, lowercasep, upcase): New static inline functions.
13832 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

13838 (regex_compile, re_search_2, re_match_2_internal):
13839 Remove unused local vars.

13842 (regex_compile, re_match_2_internal): Mark locals as initialized.
13843 (RETALLOC_IF): Define only if needed.
13844 (WORDCHAR_P): Likewise. This one is never needed, but is used
13845 only in a comment talking about a compiler bug, so put inside
13846 the #if 0 of that comment.
13847 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
13848 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

13861 * character.h (INC_POS, DEC_POS): Rename locals to avoid shadowing.
13863 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
13864 All uses changed.
13865 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
13866 Rename locals to avoid shadowing.
13867 (Fvertical_motion): Mark locals as initialized.
13869 * casefiddle.c (casify_object, casify_region): Now static.
13870 (casify_region): Mark local as initialized.

13874 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
13875 New macros, so that the caller can use some names other than
13876 gcpro1, gcpro2, etc.
13877 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
13878 of the new macros.
13879 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
13880 argument, for consistency with GCPRO2_VAR, etc: it is now the
13881 prefix of the variable, not the variable itself. All uses
13882 changed.
13883 * dired.c (directory_files_internal, file_name_completion):
13884 Rename locals to avoid shadowing.
13886 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
13887 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
13888 dired.c's scmp function, had undefined behavior.
13889 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
13890 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
13891 * buffer.h: ... to here, because these macros use current_buffer,
13892 and the new implementation with inline functions needs to have
13893 current_buffer in scope now, rather than later when the macros
13894 are used.
13895 (downcase, upcase1): New static inline functions.
13896 (DOWNCASE, UPCASE1): Reimplement using these functions.
13897 This avoids undefined behavior in expressions like
13898 DOWNCASE (x) == DOWNCASE (y), which previously suffered
13899 from race conditions in accessing the global variables
13900 case_temp1 and case_temp2.
13901 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
13902 * lisp.h (case_temp1, case_temp2): Remove their decls.
13903 * character.h (ASCII_CHAR_P): Move from here ...
13904 * lisp.h: ... to here, so that the inline functions mentioned
13905 above can use them.
13907 * dired.c (directory_files_internal_unwind): Now static.
13909 * fileio.c (file_name_as_directory, directory_file_name):
13910 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
13911 Now static.
13912 (file_name_as_directory): Use const pointers when appropriate.
13913 (Fexpand_file_name): Likewise. In particular, newdir might
13914 point at constant storage, so make it a const pointer.
13915 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
13916 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
13917 signedness issues.
13918 (Fset_file_times, Finsert_file_contents, auto_save_error):
13919 Rename locals to avoid shadowing.
13921 * minibuf.c (choose_minibuf_frame_1): Now static.
13922 (Ftry_completion, Fall_completions): Rename or remove locals
13923 to avoid shadowing.
13925 * marker.c (bytepos_to_charpos): Remove; unused.
13927 * lisp.h (verify_bytepos, count_markers): New decls,
13928 so that gcc does not warn that these functions aren't declared.
13930 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
13931 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
13932 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
13933 (copy_text): Remove unused local var.
13935 * filelock.c (within_one_second): Now static.
13936 (lock_file_1): Rename local to avoid shadowing.
13938 * buffer.c (fix_overlays_before): Mark locals as initialized.
13939 (fix_start_end_in_overlays): Likewise. This function should be
13940 simplified by using pointers-to-pointers, but that's a different
13941 matter.
13942 (switch_to_buffer_1): Now static.
13943 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
13944 (report_overlay_modification): Rename locals to avoid shadowing.
13946 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
13947 Fix pointer signedness issue.
13948 (sys_subshell): Mark local as volatile if checking for lint,
13949 to suppress a gcc -Wclobbered warning that does not seem to be right.
13950 (MAXPATHLEN): Define only if needed.
13952 * process.c (serial_open, serial_configure): Move decls from here ...
13953 * systty.h: ... to here, so that they can be checked.
13955 * fns.c (get_random, seed_random): Move extern decls from here ...
13956 * lisp.h: ... to here, so that they can be checked.
13958 * sysdep.c (reset_io): Now static.
13959 (wait_for_termination_signal): Remove; unused.
13961 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
13962 (copy_keymap_item, append_key, push_text_char_description):
13963 Now static.
13964 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
13965 (DENSE_TABLE_SIZE): Remove; unused.
13966 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
13967 (describe_map_tree):
13968 Rename locals to avoid shadowing.
13970 * keyboard.c: Declare functions static if they are not used elsewhere.
13971 (echo_char, echo_dash, cmd_error, top_level_2):
13972 (poll_for_input, handle_async_input): Now static.
13973 (read_char, kbd_buffer_get_event, make_lispy_position):
13974 (make_lispy_event, make_lispy_movement, apply_modifiers):
13975 (decode_keyboard_code, tty_read_avail_input, menu_bar_items):
13976 (parse_tool_bar_item, read_key_sequence, Fread_key_sequence):
13977 (Fread_key_sequence_vector): Rename locals to avoid shadowing.

13987 * emacs.c (init_cmdargs): Rename local to avoid shadowing.
13988 (DEFINE_DUMMY_FUNCTION): New macro.
13989 (__do_global_ctors, __do_global_ctors_aux, __do_global_dtors, __main):
13990 Use it.
13991 (main): Add casts to avoid warnings
13992 if GCC considers string literals to be constants.
13994 * lisp.h (fatal_error_signal): Add decl, since it's exported.
13996 * dbusbind.c: Pointer signedness fixes.
13997 (xd_signature, xd_append_arg, xd_initialize):
13998 (Fdbus_call_method, Fdbus_call_method_asynchronously):
13999 (Fdbus_method_return_internal, Fdbus_method_error_internal):
14000 (Fdbus_send_signal, xd_read_message_1, Fdbus_register_service):
14001 (Fdbus_register_signal): Use SSDATA when the context wants char *.
14003 * dbusbind.c (Fdbus_init_bus): Add cast to avoid warning
14004 if GCC considers string literals to be constants.

14044 * w32term.c (Vwindow_system, updating_frame):
14045 * w32uniscribe.c (initialized, uniscribe_font_driver):
14046 Remove unneeded extern declarations.
14048 2011-03-14 Chong Yidong <cyd@stupidchicken.com>
14050 * buffer.c (Fmake_indirect_buffer): Fix incorrect assertions.
14052 2011-03-13 Chong Yidong <cyd@stupidchicken.com>
