544 and continuation glyphs alike.
545 (produce_special_glyphs) [HAVE_WINDOW_SYSTEM]: Produce a stretch
546 glyph of a suitably computed width, to align the special glyphs at

727 The functional style also makes code easier to read and maintain.
728 * systime.h: Include <sys/time.h> on all hosts, not just if

770 Prefer snprintf to strncpy.
771 * nsterm.m (ns_term_init):
772 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
773 * nsterm.m (ns_term_init):
774 Avoid the need for strncpy, by using build_string or
775 make_unibyte_string directly. Use dtoastr, not snprintf.
776 * process.c (Fmake_network_process): Diagnose service names that
777 are too long, rather than silently truncating them or creating
778 non-null-terminated names.
779 (Fnetwork_interface_info): Likewise, for interface names.
780 * sysdep.c (system_process_attributes) [GNU_LINUX]:
781 Prefer sprintf to strncat.

851 O_RDONLY already includes it).
853 Stop ns builds setting the EMACSLOADPATH environment variable.
854 * nsterm.m (ns_load_path): Rename from ns_init_paths.

950 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
953 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
955 * xdisp.c (display_line): Avoid warning about implicit declaration
958 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
960 * lisp.h: Remove empty conditional.
962 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
964 * lread.c (load_path_check): Now static.
966 Fix some minor --with-ns problems found by static checking.
967 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
968 (x_set_font) [!HAVE_X_WINDOWS]:
969 * image.c (xpm_load_image) [HAVE_NS]:
970 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
971 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
973 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
974 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
975 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
976 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
977 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
978 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
979 Fix pointer signedness problem.
980 * xfaces.c (FRAME_X_FONT_TABLE):
981 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
983 2012-07-07 Glenn Morris <rgm@gnu.org>
985 * lread.c (load_path_check): New function, split from init_lread.
986 (init_lread): Reorganize. Motivation:
987 If EMACSLOADPATH is set, check/warn about that rather than the
988 defaults, which we are not going to use. Hence we can remove
989 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
990 Don't warn if site-lisp directories are missing.
991 If not installed, start from a blank load-path, since
992 PATH_LOADSEARCH refers to the eventual installation directories.
994 2012-07-07 Eli Zaretskii <eliz@gnu.org>
996 Support truncation and continuation glyphs on GUI frames, when
997 fringes are disabled. (Bug#11832)
998 * xdisp.c (init_iterator): Get dimensions of truncation and
999 continuation glyphs even if on GUI frames. Adjust
1000 it->last_visible_x on GUI frames when the left or right fringes,
1001 or both, are absent.
1002 (start_display, move_it_in_display_line_to): Handle the case of a
1003 GUI frame without a fringe to display continuation or truncation
1005 (insert_left_trunc_glyphs): Support GUI frames: make sure
1006 truncation glyphs overwrite enough glyphs from the current line to
1007 have sufficient space in pixels.
1008 (display_line): Support truncation and continuation glyphs on GUI
1009 frames. If some spare pixels are left on the line after inserting
1010 the truncation glyphs, fill that space with a stretch glyph of a
1011 suitably computed width.
1013 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
1014 produce_glyphs, to support GUI sessions.
1016 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
1018 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
1020 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
1022 Do not require float-time's arg to fit in time_t (Bug#11825).
1023 This works better on hosts where time_t is unsigned, and where
1024 float-time is applied to the (negative) difference between two times.
1025 * editfns.c (decode_time_components): Last arg is now double *,
1026 not int *, and means to store all the result as a double, without
1027 worrying about whether the seconds part fits in time_t.
1028 All callers changed.
1029 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
1030 All callers changed.
1031 (Ffloat_time): Do not fail merely because the specified time falls
1032 outside of time_t range.
1034 2012-07-07 Glenn Morris <rgm@gnu.org>
1036 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
1037 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
1038 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
1040 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
1042 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
1043 Update dependencies.
1045 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
1047 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1049 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
1050 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
1051 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
1052 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
1053 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
1054 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
1056 * xfont.c (compare_font_names): Redo to omit the need for casts.
1058 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
1060 * xfns.c (Fx_change_window_property): Doc fix.
1061 * w32fns.c (Fx_change_window_property): Doc fix.
1063 * w32fns.c (Fx_window_property): Accept the same arguments as the
1064 X Windows version. Doc fix.
1065 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
1067 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
1068 Eli Zaretskii <eliz@gnu.org>
1070 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
1071 Windows-specific code from nt/config.nt moved here.
1072 Obsolete settings removed.
1074 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1076 * process.c: Avoid unnecessary calls to gettime.
1077 (wait_reading_process_output): Don't get the time of day
1078 when gobbling data immediately and not waiting, as there's no need
1079 for it in that case. This removes a FIXME.
1081 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
1083 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
1084 is defined (Bug#11768).
1086 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1088 Fix marker debugging code.
1089 * marker.c (byte_char_debug_check): Do not perform the check
1090 if buffer is not multibyte.
1091 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
1092 Call byte_char_debug_check with correct arguments.
1094 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1096 Compile marker debugging code only if ENABLE_CHECKING is defined.
1097 * marker.c (byte_char_debug_check, count_markers):
1098 Use only if ENABLE_CHECKING is defined.
1099 (byte_debug_flag): Remove.
1100 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
1101 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
1103 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1105 Avoid code repetition in marker-related functions.
1106 * marker.c (attach_marker): New function.
1107 (Fset_marker, set_marker_restricted, set_marker_both)
1108 (set_marker_restricted_both): Use it.
1109 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
1110 Consistently rename charno to charpos.
1111 (marker_position): Add eassert.
1112 (marker_byte_position): Convert to eassert.
1114 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1116 Simplify list operations in unchain_overlay and unchain_marker.
1117 * buffer.c (unchain_overlay): Simplify. Add comment.
1118 * marker.c (unchain_marker): Simplify. Fix comments.
1120 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1122 Introduce fast path for the widely used marker operation.
1123 * alloc.c (build_marker): New function.
1124 * lisp.h (build_marker): New prototype.
1125 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
1126 * composite.c (autocmp_chars): Likewise.
1127 * editfns.c (buildmark): Remove.
1128 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
1129 (save_restriction_save): Use build_marker.
1130 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
1131 * window.c (save_window_save): Likewise.
1133 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1135 Do not use Fdelete_overlay in delete_all_overlays
1136 to avoid redundant calls to unchain_overlay.
1137 * buffer.c (drop_overlay): New function.
1138 (delete_all_overlays, Fdelete_overlay): Use it.
1139 * minibuf.c (get_minibuffer): Fix comment.
1141 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1143 Port to OpenBSD 5.1 amd64.
1144 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
1145 This is needed for OpenBSD, and should be harmless on all BSD systems.
1146 Also, include <sys/sysctl.h>, as it should be available on all
1147 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
1148 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
1149 use p_pid member, not kp_proc.pid.
1151 2012-07-06 Glenn Morris <rgm@gnu.org>
1153 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
1155 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
1157 More xmalloc and related cleanup.
1158 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
1159 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:
1160 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c:

1164 * regex.c, region-cache.c, scroll.c, search.c, sound.c, syntax.c:
1165 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
1166 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
1168 Omit needless casts involving void * pointers and allocation.
1169 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
1170 as the former is more robust if P's type is changed.
1171 Prefer xzalloc to xmalloc + memset 0.
1172 Simplify malloc-or-realloc to realloc.
1173 Don't worry about xmalloc returning a null pointer.
1174 Prefer xstrdup to xmalloc + strcpy.
1175 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
1177 * keyboard.c (apply_modifiers_uncached): Prefer local array to
1178 alloca of a constant.
1180 2012-07-05 Eli Zaretskii <eliz@gnu.org>
1182 * xdisp.c (display_line): Fix horizontal pixel coordinates when
1183 hscroll is larger than the line width. Fixes long and futile
1184 looping inside extend_face_to_end_of_line (on a TTY) producing
1185 glyphs that are not needed and thrown away.
1187 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
1189 * marker.c (set_marker_restricted_both): Simplify by using
1192 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
1194 * editfns.c (region_limit): Simplify by using clip_to_bounds.
1196 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>

1199 not defined (Bug#11768).
1200 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
1201 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
1202 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
1203 followed by gtk_box_set_homogeneous (Bug#11768).
1204 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
1205 (update_theme_scrollbar_width, xg_create_scroll_bar):
1206 Use gtk_scrollbar_new (Bug#11768).
1207 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
1208 (is_box_type): New function (Bug#11768).
1209 (xg_tool_item_stale_p): Call is_box_type.
1210 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
1211 with default display (Bug#11768).
1213 2012-07-05 Eli Zaretskii <eliz@gnu.org>
1215 * xdisp.c (window_hscroll_limited): New function.
1216 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
1217 coordinates when window's hscroll is set to insanely large
1220 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
1222 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
1223 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
1225 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
1228 * lisp.h (xzalloc): New prototype. Omit needless casts.
1229 * alloc.c (xzalloc): New function. Omit needless casts.

1281 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
1283 * fileio.c (time_error_value): Check the right error number.
1284 Problem reported by Troels Nielsen in
1285 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
1287 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1289 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
1290 This should be fixed in a better way; see Eli Zaretskii in
1291 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
1292 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
1294 * fileio.c (time_error_value): Rename from special_mtime.
1295 The old name's problems were noted by Eli Zaretskii in
1296 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
1298 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
1299 This variable's comment says Emacs needs at least one GDB-visible
1300 symbol of type enum pvec_type, to work around GDB problems.
1301 The symbol's value doesn't matter.
1303 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
1304 that causes compilation to fail on pre-C99 compilers.
1306 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
1308 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
1309 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
1311 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
1313 * buffer.c (init_buffer_once): Fix initialization of
1314 headers for buffer_defaults and buffer_local_symbols.
1315 Reported by Juanma Barranquero <lekktu@gmail.com>.
1317 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
1319 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
1320 * lisp.h (enum pvec_type): Use fewer bits.
1321 (PSEUDOVECTOR_SIZE_BITS): New constant.
1322 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
1323 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
1324 change in pvec_type.
1325 (PSEUDOVECTOR_TYPEP): New macro.
1326 (TYPED_PSEUDOVECTORP): Use it.
1327 * fns.c (internal_equal): Adapt code to extract pvectype.
1328 * emacs.c (gdb_pvec_type): Update type.
1329 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
1330 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
1331 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
1332 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
1333 (sweep_vectors): Use it. Use local var `total_bytes' instead of
1334 abusing vector->header.next.nbytes.
1335 (live_vector_p): Use PVEC_TYPE.
1336 (mark_object): Adapt code to extract pvectype. Use switch.
1338 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1340 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
1341 Tighten new eassert a bit.
1343 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
1345 Fix compilation with --enable-gcc-warnings and -O1
1347 * doprnt.c (doprnt): Change type of tem to int, initialize
1348 to avoid compiler warning. Add eassert.
1349 * search.c (simple_search): Initialize match_byte to avoid
1350 compiler warning. Add eassert.
1352 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1354 Avoid weird behavior with large horizontal scrolls.
1355 Without this change, for example, large hscroll values would
1356 mess up Emacs's display on Fedora 15 x86, presumably due to
1357 overflows in int calculations in the display code.
1358 Also, if buffers had long lines, Emacs would freeze.
1359 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
1360 (set_window_hscroll): New function, containing the old guts of
1361 Fset_window_hscroll. Return the clipped value.
1362 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
1363 This avoids the need to check against PTRDIFF_MAX.
1365 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
1367 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
1369 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
1371 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1373 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
1374 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
1375 since GCC 4.4.6 issues a bogus warning for them.
1377 Fix bugs in file timestamp newness comparisons.
1378 * fileio.c (Ffile_newer_than_file_p):
1379 * lread.c (Fload): Use full timestamp resolution of files,
1380 not just the 1-second resolution, so that files that are only
1381 slightly newer still count as newer.
1382 * fileio.c (Ffile_newer_than_file_p): Don't assume file
1383 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
1385 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
1387 * fileio.c: Improve handling of file time marker. (Bug#11852)
1388 (special_mtime): New function.
1389 (Finsert_file_contents, Fverify_visited_file_modtime):
1390 Use it to set special mtime values consistently.
1392 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
1394 * fileio.c (Finsert_file_contents): Properly handle st_mtime
1395 marker for non-existing file. (Bug#11852)
1397 2012-07-03 Glenn Morris <rgm@gnu.org>
1399 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
1400 and did not make it into globals.h).
1402 2012-07-03 Tom Tromey <tromey@redhat.com>
1404 * window.c (Fset_window_margins, Fset_window_fringes)
1405 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
1406 * textprop.c (Fprevious_property_change): No longer static.
1407 * syntax.c (Fsyntax_table_p): No longer static.
1408 * process.c (Fget_process, Fprocess_datagram_address): No longer

1448 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
1449 values which aren't power of 2.
1450 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro. Verify
1451 it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
1454 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
1456 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
1458 * alloc.c (mark_object): Revert part of last patch to use `switch'.
1460 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
1462 * alloc.c (allocate_vector_block): Remove redundant
1463 calls to mallopt if DOUG_LEA_MALLOC is defined.
1464 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
1465 avoid calls to mallopt if zero_vector is returned.
1467 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
1469 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
1470 is enabled, avoid dereferencing NULL current_sblock if
1473 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
1475 Cleanup basic buffer management.
1476 * buffer.h (struct buffer): Change layout to use generic vector
1477 marking code. Fix some comments. Change type of 'clip_changed'
1478 to bitfield. Remove unused #ifndef old.
1479 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
1480 (GET_OVERLAYS_AT): Fix indentation.
1481 (for_each_per_buffer_object_at): New macro.
1482 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)

1485 * alloc.c (allocate_buffer): Adjust to match new layout of
1486 struct buffer. Fix comment.
1487 (mark_overlay): New function.
1488 (mark_buffer): Use it. Use mark_vectorlike to mark normal
1489 Lisp area of struct buffer.
1490 (mark_object): Use it. Adjust marking of misc objects
1491 and related comments.
1493 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
1495 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
1496 wrapper that is not needed because the wrapped code is a no-op (zero
1497 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
1498 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
1500 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
1502 * alloc.c (mark_buffer): Simplify. Remove prototype.
1503 (mark_object): Add comment. Reorganize marking of vector-like
1504 objects. Use CHECK_LIVE for all vector-like objects except buffers
1505 and subroutines when GC_CHECK_MARKED_OBJECTS is defined. Avoid
1506 redundant calls to mark_vectorlike for bool vectors.
1508 2012-06-30 Glenn Morris <rgm@gnu.org>
1510 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
1512 * epaths.in (PATH_SITELOADSEARCH): New.
1513 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
1514 This is rather than relying on --enable-locallisppath elements
1515 having "site-lisp" in their names. (Bug#10208#25, 11658)
1517 2012-06-30 Eli Zaretskii <eliz@gnu.org>
1519 * w32proc.c (sys_select): Accept and ignore one more argument.
1521 * w32.c (emacs_gnutls_pull): Call select with one more argument.
1523 * sysselect.h [DOS_NT]: Don't include sys/select.h.
1524 (pselect) [!MS_DOS]: Redirect to sys_select.
1526 * sysdep.c: Don't include dos.h and dosfns.h.
1528 * process.c (sys_select):
1529 * msdos.c (sys_select): Accept one more argument and ignore it.
1531 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
1532 adapt data types and code to that.
1535 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
1536 which clashes with the gnulib function of the same name.
1538 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
1540 * font.c (font_style_to_value, font_style_symbolic)
1541 (font_prop_validate_style): Add type checks for values in
1544 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
1546 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
1549 2012-06-29 Eli Zaretskii <eliz@gnu.org>
1551 * xdisp.c (try_window_id): Undo last change.
1553 * w32.c (getwd): Adjust commentary about startup_dir.
1554 (init_environment): Always call sys_access, even in non-MSVC
1555 builds. Don't chdir to the directory of the Emacs executable.
1556 This undoes code from 1997 which was justified by the need to
1557 "avoid conflicts when removing and renaming directories". But its
1558 downside was that every relative file name was being interpreted
1559 relative to the directory of the Emacs executable, which can never
1560 be TRT. In particular, it broke sys_access when called with
1561 relative file names.
1562 (sys_access): Map GetLastError to errno.
1564 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
1566 * window.h (struct window): Change type of 'fringes_outside_margins'

1570 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
1573 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>

1582 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
1584 * editfns.c (region_limit): Fix type mismatch.
1586 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
1588 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
1589 undefined. Convert from xassert to eassert.
1590 * nsmenu.m: Convert from xassert to eassert.

1606 * window.h (struct window): Change type of 'hscroll',
1607 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
1608 'last_modified' and 'last_overlay_modified' to EMACS_INT.
1609 Adjust users accordingly.
1610 * xdisp.c (try_cursor_movement): Replace type check with eassert.
1611 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
1612 from EMACS_INT to ptrdiff_t.

1688 * alloc.c (allocate_string): Omit intervals initialization.
1689 * alloc.c (make_uninit_multibyte_string): Initialize intervals

1748 a better opportunity to optimize away calls to strlen when the
1749 function is called with compile-time constant argument.
1750 * image.c (imagemagick_error): Convert to build_string.
1751 * w32proc.c (sys_spawnve): Likewise.

1754 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
1756 Use sprintf return value instead of invoking strlen on result.
1757 In the old days this wasn't portable, since some sprintf
1758 implementations returned char *. But they died out years ago and
1759 Emacs already assumes sprintf returns int.
1760 Similarly for float_to_string.
1761 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

1769 Use sprintf or float_to_string result to avoid need to call strlen.
1770 * data.c (Fnumber_to_string):
1771 Use make_unibyte_string, since the string must be ASCII.
1772 * lisp.h, print.c (float_to_string): Now returns int length.
1773 * term.c (produce_glyphless_glyph):
1774 Use sprintf result rather than recomputing it.
1776 Clean out last vestiges of the old HAVE_CONFIG_H stuff.

1809 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from

1812 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
1814 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
1815 instead of truncating it to 63 (admittedly a generous limit).
1817 * process.c: Fix spelling and caps in comments.
1819 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>

1875 * keyboard.c (kbd_buffer_get_event):

1891 * makefile.w32-in: Update dependencies.

1896 2012-06-23 Paul Eggert <eggert@cs.ucla.edu>
1898 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
1899 Privately reported by Herbert J. Skuhra.
1900 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
1902 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,

1937 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
1938 Privately reported by Herbert J. Skuhra.

1940 (timeval_to_EMACS_TIME) [__FreeBSD__]: New static function.
1941 (TIMEVAL) [__FreeBSD__]: Now a static function rather than a macro.
1942 (TIMEVAL, system_process_attributes) [__FreeBSD__]:
1943 Don't assume EMACS_TIME and struct timeval are the same type.
1945 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
1947 Support higher-resolution time stamps (Bug#9000).
1948 The time stamps are only nanosecond-resolution at the C level,
1949 since that's the best that any real-world system supports now.
1950 But they are picosecond-resolution at the Lisp level, as that's
1951 easy, and leaves room for future OS improvements.
1953 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
1956 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
1957 Don't get current time unless it's needed.
1959 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
1960 now provides it if it's absent.
1961 (start_atimer): Port to higher-res time stamps.
1962 Check for time stamp overflow. Don't get current time more
1963 often than is needed.
1965 * buffer.h (struct buffer): Buffer modtime now has high resolution.

1973 (struct image): Timestamp now has higher resolution.
1975 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
1976 has at least microseconds now. All uses removed.
1977 (update_frame, update_single_window, update_window, update_frame_1)
1978 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
1980 * editfns.c (time_overflow): Now extern.

1988 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
1989 Report an error if the time is invalid, rather than having the caller
1992 * fileio.c: Include <stat-time.h>
1993 (Fcopy_file): Copy higher-resolution time stamps.
1994 Prefer to set the time stamp via a file descriptor if that works.

1997 (Fvisited_file_modtime, Fset_visited_file_modtime):
1998 Support higher-resolution time stamps.
2000 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
2002 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
2004 * image.c (prepare_image_for_display, clear_image_cache)
2005 (lookup_image): Port to higer-resolution time stamps.
2007 * keyboard.c (start_polling, bind_polling_period):
2008 Check for time stamp overflow.

2011 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
2012 Port to higher-resolution time stamps. Do not assume time_t is signed.
2013 (decode_timer): New function. Timers are now vectors of length 9,
2014 not 8, to accommodate the picosecond component.
2015 (timer_check_2): Use it.
2017 * nsterm.m (select_timeout, timeval_subtract): Remove.
2018 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
2019 as they're a bit more accurate and handle overflow better.
2020 (ns_select): Change prototype to be compatible with pselect.
2021 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
2022 * nsterm.h (ns_select): Adjust prototype.
2024 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
2025 us-resolution time stamps.
2026 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
2028 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
2030 * lisp.h (time_overflow): New decl.
2031 (wait_reading_process_output): First arg is now intmax_t, not int,
2032 to accommodate larger waits.
2034 * process.h (struct Lisp_Process.read_output_delay):
2035 Now counts nanoseconds, not microseconds.
2036 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about

2041 (Faccept_process_output, wait_reading_process_output):
2042 Check for time stamp overflow. Do not assume time_t is signed.
2043 (select_wrapper): Remove; we now use pselect.
2044 (Fprocess_attributes): Now generates ns-resolution time stamps.
2046 * sysdep.c: Include utimens.h. Don't include utime.h
2047 or worry about struct utimbuf; gnulib does that for us now.
2048 (gettimeofday): Remove; gnulib provides a substitute.
2049 (make_timeval): New function.
2050 (set_file_times): Now sets ns-resolution time stamps.
2051 New arg FD; all uses changed.
2052 (time_from_jiffies, ltime_from_jiffies, get_up_time)
2053 (system_process_attributes):
2054 Now returns ns-resolution time stamp. All uses changed.
2055 Check for time stamp overflow.
2057 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
2058 provides a substitute now.
2060 * systime.h: Include timespec.h rather than sys/time.h and time.h,
2061 since it guarantees struct timespec.
2062 (EMACS_TIME): Now struct timespec, so that we can support
2063 ns-resolution time stamps.
2064 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
2065 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
2066 (EMACS_USECS): Remove.
2067 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
2068 so multiply the arg by 1000 before storing it.
2069 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
2071 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
2072 Port to ns-resolution time stamps.
2073 (EMACS_TIME_NEG_P): Remove; replaced by....

2078 (make_timeval, make_lisp_time, decode_time_components): New decls.
2079 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
2080 that it mishandled time_t overflow. You can't compare by subtracting!
2081 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
2082 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.

2093 (w32_get_internal_run_time):
2094 Port to higher-resolution Emacs time stamps.

2100 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
2101 for compatibility with pselect. Support ns-resolution time stamps.

2105 * xselect.c (wait_for_property_change, x_get_foreign_selection):
2106 Check for time stamp overflow, and support ns-resolution time stamps.
2108 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
2109 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
2110 (timeval_subtract): Remove; no longer needed.
2111 (XTflash, XTring_bell, x_wait_for_event):
2112 Port to ns-resolution time stamps. Don't assume time_t is signed.
2114 2012-06-22 Chong Yidong <cyd@gnu.org>

2118 2012-06-22 Eli Zaretskii <eliz@gnu.org>
2120 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
2121 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
2122 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
2123 staticidx goes up to 1597 out of 1600 = 0x640.)
2125 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
2127 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
2128 Otherwise, the umask might be mistakenly 0 while handling input signals.

2162 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
2163 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
2164 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.

2173 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
2174 gets killed during executing of this function (Bug#11665).
2175 Try to always return Qt when the buffer has been actually killed.
2176 (Vkill_buffer_query_functions): In doc-string say that functions
2177 run by this hook should not change the current buffer.
2179 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
2181 Fix recently-introduced process.c problems found by static checking.

2202 This removes the need for CHECK.
2203 (CHECK): Remove. Its comments about always evaluating its
2204 argument were confusing, as 'eassert' typically does not evaluate
2207 * coding.c (produce_chars): Use ptrdiff_t, not int.
2209 * xterm.c (x_draw_underwave): Check for integer overflow.
2210 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

2385 Remove, as lisp.h always defines this now.
2386 (mark_maybe_pointer): Simplify since USE_LSB_TAG is always defined now.
2387 (roundup_size): Verify that it is a power of 2.
2388 * data.c (Fmake_variable_buffer_local, Fmake_local_variable):
2389 * ftfont.c (ftfont_driver): Use LISP_INITIALLY_ZERO.
2390 * lisp.h (USE_LSB_TAG): Allow the builder to compile with
2391 -DUSE_LSB_TAG=0, to override the automatically-selected default.
2392 USE_LSB_TAG now is always defined to be either 0 or 1.
2394 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
2395 code works fine either way, and efficiency is not a concern here,
2396 as the union type is for debugging, not for production.
2397 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
2398 Use an inline function on all platforms when using the union type,
2399 since this is simpler and 'static inline' can be used portably
2401 (LISP_INITIALLY_ZERO): New macro.
2402 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
2403 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.
2405 2012-06-12 Glenn Morris <rgm@gnu.org>
2407 * s/gnu-kfreebsd.h, s/hpux11.h, s/openbsd.h, s/sol2-10.h: Remove files.

2425 * image.c (imagemagick_load_image): Remove unused label.
2427 2012-06-11 Glenn Morris <rgm@gnu.org>
2429 * s/aix4-2.h, s/bsd-common.h, s/cygwin.h, s/darwin.h:
2430 * s/gnu-kfreebsd.h, s/gnu-linux.h, s/gnu.h, s/hpux10-20.h:
2431 * s/irix6-5.h, s/ms-w32.h, s/msdos.h, s/template.h:
2432 * s/usg5-4-common.h: Move SYSTEM_TYPE to configure.
2434 2012-06-11 Stefan Monnier <monnier@iro.umontreal.ca>
2436 * alloc.c (make_byte_code): New function.

2465 * dispextern.h: Replace unused TTY_CAP_BLINK with TTY_CAP_ITALIC.
2466 (struct face): Remove unused fields tty_dim_p, tty_blinking_p, and
2467 tty_alt_charset_p. Add tty_italic_p.
2469 2012-06-09 Michael Albinus <michael.albinus@gmx.de>
2471 * dbusbind.c (XD_BASIC_DBUS_TYPE): Use dbus_type_is_valid and
2472 dbus_type_is_basic if available.
2473 (xd_extract_signed, xd_extract_unsigned): Rename from
2474 extract_signed and extract_unsigned, respectively. Adapt callers.
2476 2012-06-09 Chong Yidong <cyd@gnu.org>
2478 * xfaces.c (face_for_overlay_string): Handle face remapping (Bug#2066).
2480 * fringe.c (Fset_fringe_bitmap_face): Handle the noninteractive
2483 2012-06-08 Paul Eggert <eggert@cs.ucla.edu>
2485 * xdisp.c (vmessage): Treat frame message as multibyte.
2486 Without this change, (let ((§ 1)) (make-variable-buffer-local '§))
2487 would generate the diagnostic "Making \302\247 buffer-local while
2490 2012-06-08 Eli Zaretskii <eliz@gnu.org>
2492 * dispnew.c (showing_window_margins_p): Undo last change, which

2503 2012-06-08 Juanma Barranquero <lekktu@gmail.com>
2505 * dispnew.c (showing_window_margins_p): Wrap in #if 0 to prevent unused
2506 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
2508 2012-06-08 Eli Zaretskii <eliz@gnu.org>
2510 * alloc.c (allocate_vectorlike): Fix last change.
2512 2012-06-08 Dmitry Antipov <dmantipov@yandex.ru>
2514 Block-based vector allocation of small vectors.
2515 * lisp.h (struct vectorlike_header): New field `nbytes',
2516 adjust comment accordingly.
2517 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'
2518 to denote vector blocks. Adjust users (live_vector_p,
2519 mark_maybe_pointer, valid_lisp_object_p) accordingly.
2520 (COMMON_MULTIPLE): Move outside #if USE_LSB_TAG.
2521 (VECTOR_BLOCK_SIZE, vroundup, VECTOR_BLOCK_BYTES),
2522 (VBLOCK_BYTES_MIN, VBLOCK_BYTES_MAX, VECTOR_MAX_FREE_LIST_INDEX),
2523 (VECTOR_FREE_LIST_FLAG, ADVANCE, VINDEX, SETUP_ON_FREE_LIST),
2524 (VECTOR_SIZE, VECTOR_IN_BLOCK): New macros.

2539 * eval.c (Fmacroexpand): Stop if the macro returns the same form.
2541 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
2543 * doprnt.c (doprnt): Truncate multibyte char correctly.
2544 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
2545 would mishandle a string argument "Xc" if X was a multibyte
2546 character of length 2: it would truncate after X's first byte
2547 rather than including all of X.
2549 2012-06-06 Chong Yidong <cyd@gnu.org>
2551 * buffer.c (word_wrap): Doc fix.
2553 2012-06-04 Paul Eggert <eggert@cs.ucla.edu>

2598 * minibuf.c (Fassoc_string): Remove duplicate declaration.
2600 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
2601 Convert pctcpu and pctmem to Lisp float properly.
2602 Let the compiler fold better, as 100.0/0x8000 is exact.
2604 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
2606 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
2609 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
2611 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
2613 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
2615 For a 'struct window', replace some Lisp_Object fields to
2616 bitfields where appropriate, remove unused fields.
2617 * window.h (struct window): Remove unused 'last_mark_x' and
2618 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
2619 change it's type from Lisp_Object to bitfield.
2620 Change type of 'force_start', 'optional_new_start',
2621 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
2622 fields from Lisp_Object to bitfield. Adjust users accordingly.
2624 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
2626 Pacify gcc -Wdouble-precision when using Xaw.
2627 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
2628 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
2629 Use 'float' consistently, rather than 'float' in most places
2630 and 'double' in a couple of places.
2632 2012-05-31 Eli Zaretskii <eliz@gnu.org>
2634 * xdisp.c (handle_stop): Detect whether we have overlay strings
2635 loaded by testing it->current.overlay_string_index to be
2636 non-negative, instead of checking whether n_overlay_strings is
2637 positive. (Bug#11587)
2639 2012-05-31 Chong Yidong <cyd@gnu.org>
2641 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
2643 * doc.c (Fsubstitute_command_keys): Doc fix.
2645 2012-05-31 Eli Zaretskii <eliz@gnu.org>
2647 * search.c (search_buffer): Remove calls to
2648 r_alloc_inhibit_buffer_relocation, as it is now called by
2649 maybe_unify_char, which was the cause of relocation of buffer text
2652 2012-05-31 Eli Zaretskii <eliz@gnu.org>
2654 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
2655 for the duration of call to load_charset, to avoid problems with
2656 callers of maybe_unify_char that access buffer text through C
2659 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
2660 decrement the inhibition flag, instead of just setting or
2663 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
2665 Remove obsolete '#define static' cruft.
2666 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
2667 This #undef was "temporary" in 2000; it is no longer needed
2668 now that '#define static' has gone away.
2669 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
2670 (gray_bitmap_bits): Remove; no longer needed.
2671 All uses replaced with definiens.
2672 * xterm.c: Include "bitmaps/gray.xbm".
2674 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
2676 Clean up __executable_start, monstartup when --enable-profiling.
2677 The following changes affect the code only when profiling.
2678 * dispnew.c (__executable_start): Rename from safe_bcopy.
2679 Define only on platforms that need it.
2680 * emacs.c: Include <sys/gmon.h> when profiling.
2681 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
2682 (__executable_start): Remove decl, since lisp.h does it now.
2683 (safe_bcopy): Remove decl; no longer has that name.
2684 (main): Coalesce #if into single bit of code, for simplicity.
2685 Cast pointers to uintptr_t, since standard libraries want integers

2689 2012-05-31 Glenn Morris <rgm@gnu.org>
2691 * image.c (Fimagemagick_types): Doc fix.

2709 * lisp.h (Qdefun): Remove.
2710 * lread.c (read1): Tiny simplification.
2712 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
2714 Do not create empty overlays with the evaporate property (Bug#9642).
2715 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
2716 Bug#9642, but explicitly check that the buffer the overlay would
2717 be moved to is live and rearrange lines to make sure that errors
2718 will not put the overlay in an inconsistent state.
2719 (Fdelete_overlay): Cosmetics.
2721 2012-05-28 Eli Zaretskii <eliz@gnu.org>
2723 * w32term.c (my_bring_window_to_top): New function.
2724 (x_raise_frame): Use handle returned by DeferWindowPos, which
2725 could be different from the original one.
2726 Call my_bring_window_to_top instead of my_set_foreground_window.
2729 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
2730 by calling BringWindowToTop.

2735 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
2737 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
2738 This avoids undefined behavior that might cause the eassert
2739 to not catch an out-of-range value.
2741 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
2743 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

2753 when referring to sectname field in printf format.
2755 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
2757 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
2758 Only r_alloc_inhibit_buffer_relocation needed to be added;
2759 the others were already declared.
2761 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
2762 before checking whether it's out of range. Put the check inside
2764 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
2766 2012-05-27 Ken Brown <kbrown@cornell.edu>
2768 * callproc.c (Fcall_process): Restore a line that was accidentally
2769 commented out in the 2011-02-13 change (bug#11547).

2773 * lisp.h [REL_ALLOC]: Add prototypes for external functions
2774 defined on ralloc.c.
2776 * buffer.c [REL_ALLOC]: Remove prototypes of
2777 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
2778 they are now on lisp.h.
2780 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
2782 * search.c (search_buffer): Use it to inhibit relocation of buffer
2783 text while re_search_2 is doing its job, because re_search_2 is
2784 passed C pointers to buffer text. (Bug#11519)
2786 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
2789 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
2790 state after an additional call to move_it_in_display_line_to, keep
2791 the values of it->max_ascent and it->max_descent found for the
2793 (pos_visible_p): Revert the comparison against bottom_y to what it
2794 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
2797 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
2799 Fix coding-related core dumps with gcc -ftrapv.
2800 The code was computing A - B, where A and B are pointers, and B is
2801 random garbage. This can lead to core dumps on platforms that
2802 have special pointer registers, and it also leads to core dumps on
2803 x86-64 when compiled with gcc -ftrapv. The fix is to compute
2804 A - B only when B is initialized properly.
2805 * coding.c (coding_set_source, coding_set_destination): Return void.
2806 (coding_change_source, coding_change_destinations): New functions,
2807 with the old behaviors of coding_set_source and coding_set_destination.
2808 All callers that need an offset changed to use these new functions.
2810 2012-05-26 Glenn Morris <rgm@gnu.org>
2812 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
2814 2012-05-26 Eli Zaretskii <eliz@gnu.org>
2816 Extend mouse support on W32 text-mode console.
2817 * xdisp.c (draw_row_with_mouse_face):
2818 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
2820 * w32console.c: Include window.h.
2821 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
2823 (initialize_w32_display): Initialize mouse-highlight data.
2825 * w32inevt.c: Include termchar.h and window.h.
2826 (do_mouse_event): Support mouse-autoselect-window. When the mouse
2827 moves, call note_mouse_highlight. If help_echo changed, call
2828 gen_help_event to produce help-echo message in the echo area.
2829 Call clear_mouse_face if mouse_face_hidden is set in the mouse
2832 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
2834 * lread.c (read1): Simplify slightly to avoid an overflow warning
2835 with GCC 4.7.0 on x86-64.
2837 2012-05-26 Eli Zaretskii <eliz@gnu.org>
2839 * bidi.c (bidi_mirror_char): Revert last change: an int is
2840 definitely wide enough here.
2842 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
2844 Fix integer width and related bugs (Bug#9874).
2845 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
2846 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
2847 (string_bytes, check_sblock, allocate_string_data):
2848 (compact_small_strings, Fmake_bool_vector, make_string)
2849 (make_unibyte_string, make_multibyte_string)
2850 (make_string_from_bytes, make_specified_string)
2851 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
2852 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
2854 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2855 (allocate_pseudovector):
2856 Use int, not EMACS_INT, where int is wide enough.
2857 (inhibit_garbage_collection, Fgarbage_collect):
2858 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

2876 (Foverlay_recenter, last_overlay_modification_hooks_used)
2877 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
2878 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2879 (validate_region): Omit unnecessary test for b <= e,
2880 since that's guaranteed by the previous test.

2882 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
2883 (report_overlay_modification):

2889 * buffer.h: Adjust decls to match defn changes elsewhere.

2894 not int, to avoid needless 32-bit limit on 64-bit hosts.
2895 (exec_byte_code): Use tighter memory-full test, one that checks
2896 for alloca overflow. Don't compute the address of the object just
2897 before an array, as that's not portable. Use EMACS_INT, not
2898 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
2899 * callint.c (Fcall_interactively):
2900 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

2913 (casify_object): Avoid integer overflow when overallocating buffer.
2914 * casetab.c (set_identity, shuffle): Prefer int to unsigned when

2917 * category.h (CATEGORYP): Don't assume arg is nonnegative.

2921 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2922 For CCL_MapSingle, check that content and value are in int range.

2924 Check that Vcode_version_map_vector is a vector.
2925 (resolve_symbol_ccl_program): Check that vector header is in range.
2926 Always copy the vector, so that we can check its contents reliably
2927 now rather than having to recheck each instruction as it's being
2928 executed. Check that vector words fit in 'int'.
2929 (ccl_get_compiled_code, Fregister_ccl_program)
2930 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
2931 program indexes, to avoid needless 32-bit limit on 64-bit hosts.

2933 contents are in range.
2934 (Fccl_execute_on_string): Check that status is in range.
2935 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
2936 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
2937 Accept and return EMACS_INT, not int, because callers can pass values

2946 avoid mishandling large integers.

2958 Don't assume unsigned int fits into fixnum, or that fixnum fits
2959 into unsigned int. Don't require max_code to be a valid fixnum;
2960 that's not true for gb10830 4-byte on a 32-bit host. Allow
2961 invalid_code to be a cons, for the same reason. Require code_offset
2962 to be a character. Avoid int overflow if max_char is close
2964 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
2965 this is intended anyway and avoids some undefined behavior.
2966 (load_charset_map): Pass unsigned, not int, as 2nd arg of
2967 INDEX_TO_CODE_POINT, as that's what it expects.
2968 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
2969 * charset.h (DECODE_CHAR): Return int, not unsigned;
2970 this is what was intended anyway, and it avoids undefined behavior.
2971 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
2972 integer-overflow issues.
2973 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
2974 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
2975 where the argument is EMACS_INT, and this behavior is not intended.
2976 * chartab.c (Fmake_char_table, Fset_char_table_range)
2977 (uniprop_get_decoder, uniprop_get_encoder):
2978 Don't assume fixnum fits in int.
2979 * cmds.c (move_point): New function, that does the gist of
2980 Fforward_char and Fbackward_char, but does so while checking
2981 for integer overflow more accurately.
2982 (Fforward_char, Fbackward_char): Use it.
2983 (Fforward_line, Fend_of_line, internal_self_insert)
2984 (internal_self_insert):

3640 (struct scroll_bar): Use struct vectorlike_header
3641 rather than rolling our own approximation.
3642 (SCROLL_BAR_VEC_SIZE): Remove; not used.
3644 2012-05-25 Glenn Morris <rgm@gnu.org>
3646 * lisp.mk (lisp): Update for more files being compiled now.
3648 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
3650 * lread.c: Remove `read_pure' which makes no difference.
3651 (read_pure): Remove var.
3652 (unreadpure): Remove function.
3653 (readevalloop): Don't call read_list with -1 flag.
3654 (read1, read_vector): Don't test read_pure any more.

3668 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
3671 This directory predates autoconf and is no longer needed nowadays.
3672 Move its few remaining bits of functionality to where they're needed.
3673 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:

3682 (EMACS_UINT): Define unconditionally now.
3683 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
3684 (BITS_PER_EMACS_INT): New constants, replacing
3685 what used to be in config.h, but not useful in #if.
3686 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
3687 define them any more.
3688 (VAL_MAX): New macro.
3690 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
3691 BITS_PER_EMACS_INT, in #if.
3692 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
3693 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
3694 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
3695 * s/ms-w32.h (DATA_START):
3696 Move here from removed file m/intel386.h.
3697 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
3698 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
3700 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
3702 Assume C89 or later.

3711 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
3712 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
3713 * xterm.c (input_signal_count): Assume volatile works.
3715 2012-05-21 Ken Brown <kbrown@cornell.edu>
3717 * xgselect.c (xg_select): Fix first argument in call to 'select'
3720 2012-05-20 Ken Brown <kbrown@cornell.edu>
3722 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
3723 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
3725 2012-05-19 Ken Brown <kbrown@cornell.edu>
3727 * xfns.c (x_in_use): Remove `static' qualifier.
3728 * xterm.h (x_in_use): Declare.
3729 * xgselect.c: Include xterm.h.
3730 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
3731 and `display_arg' (bug#9754).
3733 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
3735 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
3737 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
3738 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
3740 2012-05-18 Eli Zaretskii <eliz@gnu.org>
3742 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
3744 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
3745 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
3747 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
3748 reference to image_cache->refcount.
3749 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
3751 2012-05-17 Juri Linkov <juri@jurta.org>
3753 * search.c (Fword_search_regexp, Fword_search_backward)
3754 (Fword_search_forward, Fword_search_backward_lax)
3755 (Fword_search_forward_lax): Move functions to isearch.el
3756 (bug#10145, bug#11381).
3758 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
3760 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
3762 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
3764 * lread.c (init_obarray): Declare Qt and Qnil as special.
3766 2012-05-14 Glenn Morris <rgm@gnu.org>
3768 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
3769 Put "libexec" before "bin", for the sake of init_callproc_1.
3771 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
3773 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
3775 * unexaix.c: Port to more-recent AIX compilers.
3776 (report_error, report_error_1, make_hdr, copy_sym)
3777 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
3778 Make arguments const char *, not char *, to avoid violations of C
3779 standard and to fix some AIX warnings reported by Gilles Pion.
3781 2012-05-14 Eli Zaretskii <eliz@gnu.org>
3783 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
3784 already have overlays loaded.
3785 (handle_single_display_spec): Before returning without displaying
3786 fringe bitmap, synchronize the bidi iterator with the main display
3787 iterator, by calling iterate_out_of_display_property.
3788 (iterate_out_of_display_property): Detect buffer iteration by
3789 testing that it->string is a Lisp string.
3790 (get_next_display_element): When the current object is exhausted,
3791 and there's something on it->stack, call set_iterator_to_next to
3792 proceed with what's on the stack, instead of returning zero.
3793 (set_iterator_to_next): If called at the end of a Lisp string,
3794 proceed to consider_string_end without incrementing string
3795 position. Don't increment display vector index past the end of
3796 the display vector. (Bug#11417)
3797 (pos_visible_p): Don't report a position visible when move_it_to
3798 stopped at the last line of window, which happens to be scanned
3799 backwards by the bidi iteration. (Bug#11464)
3801 2012-05-14 Eli Zaretskii <eliz@gnu.org>
3803 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
3804 and right-margin display specs even if the spec is invalid or we
3805 are on a TTY, and thus unable to display on the fringes.
3806 That's because the text with the property will not be displayed anyway,
3807 so we need to signal to the caller that this is a "replacing"
3808 display spec. This fixes display when the spec is invalid or we
3811 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
3813 * unexaix.c (make_hdr): Fix typo in prototype.
3814 This bug broke the build on AIX. Problem reported by Gilles Pion.
3816 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
3818 * keyboard.c (kbd_buffer_get_event): Read special events also in
3819 batch mode. (Bug#11415)
3821 2012-05-12 Glenn Morris <rgm@gnu.org>
3823 * ns.mk: Update for ns_appbindir no longer having trailing "/".
3825 2012-05-12 Eli Zaretskii <eliz@gnu.org>
3827 * lisp.mk (lisp): Add newcomment.elc.
3829 2012-05-12 Glenn Morris <rgm@gnu.org>
3831 * Makefile.in (MKDIR_P): New, set by configure.
3832 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
3834 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
3836 Remove unused function hourglass_started.
3837 * dispextern.h (hourglass_started):
3838 * w32fns.c (hourglass_started):
3839 * xdisp.c (hourglass_started): Remove.
3841 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
3843 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
3844 Update dependencies.
3846 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
3848 * xgselect.c (xg_select): Put maxfds+1 into a var.
3849 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
3851 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
3853 2012-05-10 Dave Abrahams <dave@boostpro.com>
3855 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
3856 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
3858 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
3860 * dbusbind.c (xd_registered_buses): New internal Lisp object.
3861 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
3862 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
3863 Initialize xd_registered_buses.
3865 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
3867 Untag more efficiently if USE_LSB_TAG.
3868 This is based on a proposal by YAMAMOTO Mitsuharu in
3869 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
3870 For an admittedly artificial (nth 8000 longlist) benchmark on
3871 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
3872 Emacs's overall text size by 1%.
3873 * lisp.h (XUNTAG): New macro.
3874 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
3875 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
3876 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
3877 * eval.c (Fautoload):
3878 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
3879 * frame.h (XFRAME): Use XUNTAG.
3881 Port recent dbusbind.c changes to 32-bit --with-wide-int.
3882 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
3883 Remove unportable assumptions about print widths of types like
3885 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
3886 intptr_t when converting between pointer and integer, to avoid GCC
3887 warnings about wrong width.
3889 2012-05-09 Eli Zaretskii <eliz@gnu.org>
3891 * w32proc.c (new_child): Force Windows to reserve only 64KB of
3892 stack for each reader_thread, instead of defaulting to 8MB
3893 determined by the linker. This avoids failures in creating
3894 subprocesses on Windows 7, see the discussion in this thread:
3895 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
3897 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
3899 Fix up display of the *Minibuf-0* buffer in the mini window.
3900 * keyboard.c (read_char): Don't clear the echo area if there's no
3902 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
3903 contents of *Minibuf-0*) if there's no message displayed in its stead.
3905 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
3907 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
3910 2012-05-06 Chong Yidong <cyd@gnu.org>
3912 * lisp.mk (lisp): Update.
3914 2012-05-05 Jim Meyering <meyering@redhat.com>
3916 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
3918 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
3920 * data.c (PUT_ERROR): New macro.
3921 (syms_of_data): Use it. Add new error type `user-error'.
3922 * undo.c (user_error): New function.
3923 (Fprimitive_undo): Use it.
3924 * print.c (print_error_message): Adjust print style for `user-error'.
3925 * keyboard.c (user_error): New function.
3926 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
3928 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
3930 Do not limit current-time-string to years 1000..9999.
3931 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
3932 (Fcurrent_time_string): Support any year that is supported by the
3933 underlying localtime representation. Don't use asctime, as it
3934 has undefined behavior for years outside the range -999..9999.
3936 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
3938 Fix race conditions involving setenv, gmtime, localtime, asctime.
3939 Without this fix, interrupts could mess up code that uses these
3940 nonreentrant functions, since setting TZ invalidates existing
3941 tm_zone or tzname values, and since most of these functions return
3942 pointers to static storage.
3943 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
3944 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
3945 Grow the critical sections to include not just invoking
3946 localtime/gmtime, but also accessing these functions' results
3947 including their tm_zone values if any, and any related TZ setting.
3948 (format_time_string): Last arg is now struct tm *, not struct tm **,
3949 so that the struct tm is saved in the critical section.
3950 All callers changed. Simplify allocation of initial buffer, partly
3951 motivated by the fact that memory allocation needs to be outside
3952 the critical section.
3954 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
3956 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
3957 with RESET_INTERVAL.
3959 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
3960 Remove duplicated buffer name initialization.
3962 2012-05-02 Jim Meyering <jim@meyering.net>
3964 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
3966 * xfns.c (x_window): Use xstrdup (Bug#11375).
3968 2012-05-02 Eli Zaretskii <eliz@gnu.org>
3970 * xdisp.c (pos_visible_p): If already at a newline from the
3971 display string before the 'while' loop, don't walk back the glyphs
3972 from it3.glyph_row. Solves assertion violation when the display
3973 string begins with a newline (egg.el). (Bug#11367)
3975 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
3977 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
3980 2012-05-01 Glenn Morris <rgm@gnu.org>
3982 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
3983 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
3984 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
3985 All were removed before 23.1.
3987 * dispnew.c: Remove HAVE_LIBNCURSES test;
3988 it is always true on relevant platforms.
3990 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
3991 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
3993 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.

4003 Do not avoid creating empty evaporating overlays (Bug#9642).
4004 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
4005 That is, do not delete an evaporating overlay if it becomes
4006 empty after its bounds are adjusted to fit within its buffer.
4007 This fix caused other problems, and I'm reverting it until we get
4008 to the bottom of them.
4010 2012-04-27 Chong Yidong <cyd@gnu.org>
4012 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
4014 2012-04-27 Eli Zaretskii <eliz@gnu.org>
4016 * xdisp.c (pos_visible_p): If the window start position is beyond
4017 ZV, start the display from buffer beginning. Prevents assertion
4018 violation in init_iterator when the minibuffer window is scrolled
4021 * window.c (window_scroll_pixel_based): Likewise.
4023 2012-04-27 Chong Yidong <cyd@gnu.org>

4040 display element, check also the underlying string or buffer
4041 character. (Bug#11341)
4043 * w32menu.c: Include w32heap.h.
4044 (add_menu_item): If the call to AppendMenuW (via
4045 unicode_append_menu) fails, disable Unicode menus only if we are
4046 running on Windows 9X/Me.
4048 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
4050 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.

4053 2012-04-24 Martin Rudalics <rudalics@gmx.at>
4055 * keyboard.c (read_char): Don't wipe echo area for select window

4062 manipulation of :loaded-from data.
4064 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
4066 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
4067 now a cons (bug#11311).
4069 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
4071 Do not create empty overlays with the evaporate property (Bug#9642).
4072 * buffer.c (Fmove_overlay): Delete an evaporating overlay
4073 if it becomes empty after its bounds are adjusted to fit within
4074 its buffer. Without this fix, in a nonempty buffer (let ((o
4075 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
4076 yields an empty overlay that has the evaporate property, which is
4077 not supposed to happen.
4079 Fix minor GTK3 problems found by static checking.
4080 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)

4100 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
4101 (__malloc_size_t, __malloc_ptrdiff_t):

4181 since the two debugging options are incompatible.
4182 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
4184 (mem_init, mem_insert, mem_insert_fixup):
4185 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

4194 * sysdep.c [__FreeBSD__]: Minor cleanups.
4195 (list_system_processes, system_process_attributes) [__FreeBSD__]:
4196 Use Emacs indenting style more consistently. Avoid some casts.
4197 Use 'double' consistently rather than mixing 'float' and 'double'.

4217 (print_object): Check for cycles even when print-circle is nil and
4218 print-gensym is t, but only check print_depth if print-circle is nil.
4220 2012-04-20 Chong Yidong <cyd@gnu.org>
4222 * process.c (wait_reading_process_output): If EIO occurs on a pty,
4223 set the status to "failed" and ensure that sentinel is run.

4278 New extern decls, to avoid calling undeclared functions.
4279 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
4280 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
4281 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
4282 (NEED_MEM_INSERT): New macro.
4283 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
4284 Remove one incorrect comment and fix another.

4298 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
4299 Remove decls. This fixes an "It stinks!".
4301 * alloc.c (which_symbols): Fix alignment issue / type clash.
4303 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
4305 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

4325 no longer the default.
4326 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
4328 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

4351 2012-04-11 Daniel Colascione <dancol@dancol.org>
4353 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
4354 against is gone. It's better to use vfork now so that when Cygwin
4355 gains a new, working vfork, we use it automatically (bug#10398).
4357 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

4378 being loaded (bug#10424).
4380 2012-04-09 Glenn Morris <rgm@gnu.org>
4382 * doc.c (Fsnarf_documentation): Check variables, functions are bound,

4395 Add convenience `GNUTLS_LOG2i' macro.
4397 * gnutls.c (gnutls_log_function2i): Convenience log function.
4398 (emacs_gnutls_read): Use new log functions,
4399 `gnutls_handshakes_tried' process member, and
4400 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
4401 attempts per process (connection).
4403 2012-04-09 Chong Yidong <cyd@gnu.org>

4410 * minibuf.c (Fread_variable): Callers changed.
4412 2012-04-09 Eli Zaretskii <eliz@gnu.org>
4414 * xdisp.c (set_cursor_from_row): If the display string appears in
4415 the buffer at position that is closer to point than the position
4416 after the display string, display the cursor on the first glyph of
4417 the display string. Fixes cursor display when a 'display' text
4418 property immediately follows invisible text. (Bug#11094)
4420 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
4422 composite.c: use 'double' consistently
4423 * composite.c (get_composition_id): Use 'double' consistently
4424 instead of converting 'float' to 'double' and vice versa; this is
4425 easier to understand and avoids a GCC warning.
4427 2012-04-09 Glenn Morris <rgm@gnu.org>
4429 * Makefile.in: Generate leim-list with bootstrap-emacs, in
4430 preparation for dumping it with emacs. (Bug#4789)

4451 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
4452 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
4453 (mark_memory): Mark Lisp_Objects only if pointers might hide in
4454 objects, as mark_maybe_pointer will catch them otherwise.
4455 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
4456 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
4458 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
4460 Fix typo that broke non-Windows builds.
4461 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.

4474 [!WINDOWSNT]: New macros.
4475 (init_libxml2_functions, libxml2_loaded_p): New functions.
4476 (parse_region): Call fn_xmlCheckVersion instead of using the macro
4477 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
4478 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
4479 Calls xmlCleanupParser only if libxml2 was loaded (or statically
4481 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
4482 Call init_libxml2_functions before calling libxml2 functions.
4483 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
4485 * emacs.c: Don't include libxml/parser.h.
4486 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
4487 xmlCleanupParser directly.
4489 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
4491 2012-04-07 Eli Zaretskii <eliz@gnu.org>
4493 * indent.c (Fvertical_motion): If there is a display string at
4494 point, use it.vpos to compute how many lines to backtrack after

4499 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
4500 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
4501 about subtle differences between FETCH_CHAR* and STRING_CHAR*
4502 macros related to unification of CJK characters. For the details,
4503 see the discussion following the message here:
4504 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
4506 2012-04-04 Chong Yidong <cyd@gnu.org>
4508 * keyboard.c (Vdelayed_warnings_list): Doc fix.
4510 2012-04-01 Eli Zaretskii <eliz@gnu.org>
4512 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA

4520 2012-03-31 Eli Zaretskii <eliz@gnu.org>
4522 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
4523 position we get to after a call to move_it_to fails the
4524 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
4525 only if we wind up in a string from display property. (Bug#11063)
4527 * window.c (Fdelete_other_windows_internal): Invalidate the row
4528 and column information about mouse highlight, so that redisplay
4529 restores it after reallocating the glyph matrices. (Bug#7464)
4531 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
4532 string comes from a `display' text property, use the buffer
4533 position of that property as if we actually saw that position in
4535 (move_it_by_lines): Remove the assertion that
4536 "it->current_x == 0 && it->hpos == 0" which can be legitimately
4537 violated when there's a before-string at the beginning of a line.
4540 2012-03-30 Eli Zaretskii <eliz@gnu.org>
4542 * xdisp.c (append_space_for_newline): If the default face was
4543 remapped, use the remapped face for the appended newline.
4544 (extend_face_to_end_of_line): Use the remapped default face for
4545 extending the face to the end of the line.
4546 (display_line): Call extend_face_to_end_of_line when the default
4547 face was remapped. (Bug#11068)
4549 2012-03-29 Eli Zaretskii <eliz@gnu.org>
4551 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.

4562 2012-03-26 Kenichi Handa <handa@m17n.org>
4564 * dispextern.h (struct glyph): Fix previous change. Change the
4565 bit length of glyphless.ch to 25 (Bug#11082).
4567 2012-03-26 Chong Yidong <cyd@gnu.org>
4569 * keyboard.c (Vselection_inhibit_update_commands): New variable.
4570 (command_loop_1): Use it; inhibit selection update for
4571 handle-select-window too (Bug#8996).
4573 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
4575 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
4577 2012-03-25 Kenichi Handa <handa@m17n.org>
4579 * dispextern.h (struct glyph): Change the bit length of
4580 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
4582 2012-03-24 Eli Zaretskii <eliz@gnu.org>
4584 * s/ms-w32.h (tzname): Include time.h before redirecting to
4585 _tzname. Fixes the MSVC build. (Bug#9960)
4587 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
4589 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
4592 * xterm.c (XTread_socket): Only modify handling_signal if
4593 !SYNC_INPUT. (Bug#11080)
4595 2012-03-23 Eli Zaretskii <eliz@gnu.org>
4597 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
4598 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
4599 when fetching a multibyte character consumes more bytes than
4600 CHAR_BYTES returns, due to unification of CJK characters in
4601 string_char. (Bug#11073)
4603 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
4605 * process.c (wait_reading_process_output): Handle pty disconnect
4606 by refraining from sending oneself a SIGCHLD (bug#10933).
4608 2012-03-22 Chong Yidong <cyd@gnu.org>

4621 2012-03-20 Eli Zaretskii <eliz@gnu.org>
4623 * w32proc.c (Fw32_set_console_codepage)
4624 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):

4629 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
4630 to reflect default non-nil value of redisplay-dont-pause.
4632 2012-03-19 Kenichi Handa <handa@m17n.org>

4635 it fit in a valid range (Bug#11003).
4637 2012-03-18 Eli Zaretskii <eliz@gnu.org>
4639 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
4640 that is not from display property, accept the row as a "cursor
4641 row" if one of the string's character has a non-nil `cursor'
4642 property. Fixes cursor positioning when there are newlines in
4643 overlay strings, e.g. in icomplete.el. (Bug#11035)
4645 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
4647 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
4649 2012-03-12 Chong Yidong <cyd@gnu.org>
4651 * eval.c (inhibit_lisp_code): Rename from
4652 inhibit_window_configuration_change_hook; move from window.c.
4654 * xfns.c (unwind_create_frame_1, Fx_create_frame):
4655 * window.c (run_window_configuration_change_hook)
4656 (syms_of_window): Callers changed.
4658 2012-03-11 Chong Yidong <cyd@gnu.org>

4671 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
4673 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
4675 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
4676 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
4679 2012-03-03 Glenn Morris <rgm@gnu.org>
4681 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
4683 2012-03-02 Eli Zaretskii <eliz@gnu.org>
4685 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
4686 position past the first glyph_row that ends at ZV. (Bug#10902)
4687 (redisplay_window, next_element_from_string): Fix typos in
4689 (redisplay_window): Pass to move_it_vertically the margin in
4690 pixels, not in screen lines.
4692 2012-03-02 Glenn Morris <rgm@gnu.org>
4694 * buffer.c (buffer-list-update-hook): Doc fix.
4696 2012-02-29 Eli Zaretskii <eliz@gnu.org>
4698 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
4699 push_it before setting up the iterator for the first overlay
4700 string, even if we have an empty string loaded.
4701 (next_overlay_string): If there's an empty string on the iterator
4702 stack, pop the stack. (Bug#10903)
4704 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
4706 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
4707 Suggested by Stefan Monnier in
4708 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
4709 * alloc.c (widen_to_Lisp_Object): New static function.
4710 (mark_memory): Also mark Lisp_Objects by fetching pointer words
4711 and widening them to Lisp_Objects. This would work even if
4712 USE_LSB_TAG is defined and wide integers are used, which might
4713 happen in a future version of Emacs.
4715 2012-02-25 Chong Yidong <cyd@gnu.org>
4717 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
4720 * xselect.c (Fx_selection_exists_p): Doc fix.
4721 (x_clipboard_manager_save_all): Print an informative message
4722 before saving to clipboard manager.
4724 2012-02-24 Chong Yidong <cyd@gnu.org>
4726 * keyboard.c (process_special_events): Handle all X selection
4727 requests in kbd_buffer, not just the next one (Bug#8869).
4729 2012-02-23 Chong Yidong <cyd@gnu.org>
4731 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
4732 call when setting menu-bar-lines and tool-bar-lines parameters.
4733 (unwind_create_frame_1): New helper function.
4735 * window.c (inhibit_window_configuration_change_hook): New var.
4736 (run_window_configuration_change_hook): Obey it.
4737 (syms_of_window): Initialize it.
4739 2012-02-22 Chong Yidong <cyd@gnu.org>
4741 * xterm.c (x_draw_image_relief): Add missing type check for
4742 Vtool_bar_button_margin (Bug#10743).

4746 * fileio.c (Vfile_name_handler_alist): Doc fix.
4748 * buffer.c (Fget_file_buffer): Protect against invalid file
4749 handler return value.
4751 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
4753 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
4754 when computing $valmask.
4756 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
4757 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
4758 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
4759 It's useless in that case, and it can cause problems on hosts
4760 that allocate halves of EMACS_INT values separately.
4761 Reported by Dan Horák. Diagnosed by Andreas Schwab in
4762 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
4763 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
4764 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
4765 it avoids undefined behavior on hosts where shifting right by more
4766 than the word width has undefined behavior.
4768 2012-02-19 Chong Yidong <cyd@gnu.org>
4770 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
4771 (Funhandled_file_name_directory, Ffile_name_as_directory)
4772 (Fdirectory_file_name, Fexpand_file_name)
4773 (Fsubstitute_in_file_name): Protect against invalid file handler
4774 return values (Bug#10845).
4776 2012-02-18 Eli Zaretskii <eliz@gnu.org>

4788 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
4790 2012-02-15 Chong Yidong <cyd@gnu.org>
4792 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
4793 marked as special. Also, starting docstrings with * is obsolete.
4795 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
4797 * gnutls.c (emacs_gnutls_write): Fix last change.
4799 2012-02-13 Lars Ingebrigtsen <larsi@gnus.org>

4804 2012-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
4806 * keymap.c (Fsingle_key_description): Handle char ranges.
4808 2012-02-12 Chong Yidong <cyd@gnu.org>
4810 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
4811 as that creates a dangerous corner case.
4813 * window.c (Fdelete_window_internal): Invalidate the mouse
4814 highlight (Bug#9904).
4816 2012-02-12 Glenn Morris <rgm@gnu.org>
4818 * xselect.c (Fx_own_selection_internal)
4819 (Fx_get_selection_internal, Fx_disown_selection_internal)
4820 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
4821 * nsselect.m (Fx_own_selection_internal)
4822 (Fx_disown_selection_internal, Fx_selection_exists_p)
4823 (Fx_selection_owner_p, Fx_get_selection_internal):
4824 Sync docs and argument specs with the xselect.c versions.
4826 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
4828 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
4830 2012-02-11 Eli Zaretskii <eliz@gnu.org>

4846 2012-02-07 Chong Yidong <cyd@gnu.org>
4848 * buffer.c (Fbuffer_local_variables)
4849 (buffer_lisp_local_variables): Handle unbound vars correctly;
4850 don't let Qunbound leak into Lisp.
4852 2012-02-07 Glenn Morris <rgm@gnu.org>
4854 * image.c (Fimagemagick_types): Doc fix.
4856 * image.c (imagemagick-render-type): Change it from a lisp object
4857 to an integer. Move the doc here from the lisp manual.

4860 2012-02-06 Chong Yidong <cyd@gnu.org>
4862 * doc.c (store_function_docstring): Avoid applying docstring of
4863 alias to base function (Bug#2603).
4865 2012-02-04 Andreas Schwab <schwab@linux-m68k.org>
4867 * .gdbinit (pp1, pv1): Remove redundant defines.
4870 2012-02-04 Chong Yidong <cyd@gnu.org>
4872 * nsterm.m: Declare a global (Bug#10694).
4874 2012-02-04 Eli Zaretskii <eliz@gnu.org>
4876 * w32.c (get_emacs_configuration_options):
4877 Include --enable-checking, if specified, in the return value.
4879 2012-02-04 Martin Rudalics <rudalics@gmx.at>
4881 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
4882 after rounding frame sizes. (Bug#9723)
4884 2012-02-04 Eli Zaretskii <eliz@gnu.org>
4886 * keyboard.c (adjust_point_for_property): Don't position point
4887 before BEGV. (Bug#10696)
4889 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
4891 Handle overflow when computing char display width (Bug#9496).
4892 * character.c (char_width): Return EMACS_INT, not int.
4893 (char_width, c_string_width): Check for overflow when
4894 computing the width; this is possible now that individual
4895 characters can have unbounded width. Problem introduced
4896 by merge from Emacs 23 on 2012-01-19.
4898 2012-02-02 Michael Albinus <michael.albinus@gmx.de>
4900 * dbusbind.c (Fdbus_register_method): Mention the return value

4913 2012-02-02 Kenichi Handa <handa@m17n.org>
4915 (x_produce_glyphs): Cancel previous change. If cmp->glyph_len is
4916 0, do not call append_composite_glyph.
4918 2012-02-02 Kenichi Handa <handa@m17n.org>
4920 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
4922 (x_produce_glyphs): If the component of a composition is a null
4923 string, set it->pixel_width to 1 to avoid zero-width glyph.
4925 2012-02-01 Eli Zaretskii <eliz@gnu.org>
4927 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
4928 first 2 arguments are identical. This makes inserting large
4929 output from a subprocess an order of magnitude faster on
4930 MS-Windows, where all sbrk'ed memory is always contiguous.

5460 * xdisp.c (redisplay_window): If cursor row is not fully visible
5461 after recentering, and scroll-conservatively is set to a large
5462 number, scroll window by a few more lines to make the cursor fully
5463 visible and out of scroll-margin. (Bug#10105)
5464 (start_display): Don't move to the next line if the display should
5465 start at a newline that is part of a display vector or an overlay

5549 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
5550 is set, removing the need for VIRT_ADDRESS_VARIES.
5551 (PURE_P): Use a more-efficient implementation that needs just one
5552 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
5553 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
5554 to 4 (xorl, subq, cmpq, setbe).
5555 * alloc.c (pure): Always extern now, since that's the
5556 VIRT_ADDR_VARIES behavior.
5557 (PURE_POINTER_P): Use a single comparison, not two, for
5558 consistency with the new puresize.h.
5559 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.

5566 (erase_phys_cursor, update_window_cursor, show_mouse_face)
5567 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
5568 behave as if the cursor position were at the window margin.
5570 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
5571 and the cursor position is out of bounds, behave as if the cursor
5572 position were at the window margin. (Bug#10075)
5574 2011-11-18 Chong Yidong <cyd@gnu.org>
5576 * window.c (Fwindow_combination_limit): Make first argument

5598 compute_line_metrics.
5599 (compute_line_metrics): Call row_hash, instead of computing the
5602 * dispnew.c (verify_row_hash): Call row_hash for computing the
5603 hash code of a row, instead of duplicating code from xdisp.c.
5605 * dispextern.h (row_hash): Add prototype.
5607 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>

5637 occurrences of window_nest to window_combination_limit.
5639 2011-11-15 Juanma Barranquero <lekktu@gmail.com>
5641 * image.c (imagemagick_load_image): Fix typo.
5643 2011-11-14 Eli Zaretskii <eliz@gnu.org>
5645 * xdisp.c (display_line): Move the call to
5646 highlight_trailing_whitespace before the call to
5647 compute_line_metrics, since the latter needs to see the final
5648 faces of all the glyphs to compute ROW's hash value.
5649 Fixes assertion violations in row_equal_p. (Bug#10035)
5651 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
5653 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,

5658 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
5659 with user-defined heap size. Bump the default size of the temacs
5660 heap to 27MB, to avoid memory warning when running temacs.
5661 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
5663 * dispnew.c (scrolling_window): Fix incorrect indices in accessing

5710 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
5712 Avoid some portability problems by eschewing 'extern inline' functions.
5713 The trivial performance wins aren't worth the portability hassles; see
5714 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
5716 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

5718 (window_box_right, window_box_right_offset): Undo previous change,
5719 by removing the "extern"s.
5720 * intervals.c (adjust_intervals_for_insertion)
5721 (adjust_intervals_for_deletion): Undo previous change,
5722 making these static again.
5723 (offset_intervals, temp_set_point_both, temp_set_point)
5724 (copy_intervals_to_string): No longer inline.
5725 * xdisp.c (window_text_bottom_y, window_box_width)

5790 (window_box_width, window_box_left, window_box_left_offset)
5791 (window_box_right, window_box_right_offset): Declare extern.
5792 Otherwise, these inline functions do not conform to C99 and
5793 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
5794 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
5795 * intervals.c (adjust_intervals_for_insertion)
5796 (adjust_intervals_for_deletion): Now extern, because otherwise the

5798 (static_offset_intervals): Remove.
5799 (offset_intervals): Rewrite using the old contents of
5800 static_offset_intervals. The old version didn't conform to C99
5801 because an extern inline function contained a reference to an
5802 identifier with static linkage.
5804 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
5806 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

5824 (Fwindow_vscroll): Doc fix.
5825 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
5826 argument, since it makes no sense to pass a live window and for

5855 (unwind_create_frame): New function (Bug#9943).
5856 (Fx_create_frame): Restructure code to be more similar to the one in
5857 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).
5858 Initialize image_cache_refcount if GLYPH_DEBUG (Bug#9943).
5859 Move terminal->reference_count++ just before making the frame official

5904 * regex.c <re_char> [_MSC_VER]: A separate definition for MSVC.
5906 2011-11-04 Eli Zaretskii <eliz@gnu.org>
5908 * xdisp.c (note_mouse_highlight): If either of
5909 previous/next-single-property-change returns nil, treat that as
5910 the beginning or the end of the buffer. (Bug#9955)
5912 2011-11-04 Jan Djärv <jan.h.d@swipnet.se>
5914 * gtkutil.c (xg_make_tool_item): Add callbacks if one of wimage or
5915 label is not null (Bug#9951).

5926 * xdisp.c (note_mouse_highlight): Initialize `area'. (Bug#9947)
5928 * w32fns.c (unwind_create_frame): If needed, free the glyph
5929 matrices of the partially constructed frame. (Bug#9943)
5930 * xfns.c (unwind_create_frame): Likewise.
5932 2011-11-01 Eli Zaretskii <eliz@gnu.org>
5934 * xdisp.c (mouse_face_from_buffer_pos): Fix a typo in a comment.
5935 Don't stop backward scan on the continuation glyph, even though
5936 its CHARPOS is positive.
5937 (mouse_face_from_buffer_pos, note_mouse_highlight):
5938 Rename cover_string to disp_string.
5940 2011-11-01 Martin Rudalics <rudalics@gmx.at>
5942 * window.c (temp_output_buffer_show): Don't use
5943 Vtemp_buffer_show_specifiers.
5944 (Vtemp_buffer_show_specifiers): Remove unused variable.
5946 2011-10-30 Eli Zaretskii <eliz@gnu.org>
5948 * xdisp.c (try_cursor_movement): Make sure ROW isn't decremented
5949 past the beginning of the current glyph matrix.
5951 2011-10-30 Adam Sjøgren <asjo@koldfront.dk> (tiny change)
5953 * xterm.c: Include X11/Xproto.h if HAVE_GTK3.
5954 (x_error_handler): Ignore BadMatch for X_SetInputFocus for
5955 HAVE_GTK3 (Bug#9869).
5957 * gtkutil.c (xg_win_to_widget, xg_event_is_for_menubar): Initialize
5958 type to GDK_NOTHING so valgrind does not complain (Bug#9901).
5960 * xterm.h (x_display_info): Add Xatom_net_wm_state_hidden (Bug#9893).
5962 * xterm.c: Declare x_handle_net_wm_state to return int.

5971 2011-10-29 Paul Eggert <eggert@cs.ucla.edu>
5973 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
5974 so that this new function doesn't get optimized away by a
5975 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
5977 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
5979 * frame.h (MOUSE_HL_INFO): Remove excess parens.
5981 2011-10-29 Eli Zaretskii <eliz@gnu.org>
5983 Fix the `xbytecode' command.
5984 * .gdbinit (xprintbytestr): New command.
5985 (xwhichsymbols): Rename from `which'; all callers changed.
5986 (xbytecode): Print the byte-code string as well.
5988 2011-10-29 Kim Storm <storm@cua.dk>
5990 * alloc.c (which_symbols): New function.
5992 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
5994 * minibuf.c (read_minibuf_noninteractive): Allow reading empty
5997 2011-10-29 Glenn Morris <rgm@gnu.org>
5999 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
6000 Not clear what it was for, and it causes various bugs. (Bug#9839)
6002 2011-10-28 Eli Zaretskii <eliz@gnu.org>
6004 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
6005 possible random value that matches one of those tested as
6006 condition to clear the mouse face.
6008 2011-10-28 Chong Yidong <cyd@gnu.org>
6010 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.
6012 2011-10-28 Dan Nicolaescu <dann@ics.uci.edu>
6014 * window.c (make_window): Initialize phys_cursor_on_p.
6016 2011-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
6018 * lisp.h (struct Lisp_Symbol): Update comments.
6020 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
6022 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
6024 2011-10-28 Eli Zaretskii <eliz@gnu.org>
6026 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
6027 <oslsachem@gmail.com> for helping to debug this.
6029 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
6030 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
6031 (g_b_init_get_glyph_outline_w): New static variables.
6032 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
6033 (GetGlyphOutlineW_Proc): New typedefs.
6034 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
6035 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
6037 (w32font_open_internal, compute_metrics):
6038 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
6039 instead of calling the "wide" APIs directly.
6041 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
6043 * w32.h (syms_of_w32font): Add prototype.
6045 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
6047 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
6048 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
6049 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.

6052 2011-10-27 Chong Yidong <cyd@gnu.org>
6054 * process.c (make_process): Set gnutls_state to NULL.
6056 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
6057 non-NULL, regardless of GNUTLS_INITSTAGE.
6058 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
6059 an error. Set process slots as soon as we allocate them.
6061 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
6063 2011-10-27 Chong Yidong <cyd@gnu.org>

6069 * process.c (make_process): Initialize GnuTLS credentials to NULL.
6070 (deactivate_process): Call emacs_gnutls_deinit.
6072 2011-10-27 Juanma Barranquero <lekktu@gmail.com>

6076 * w32font.c (fill_in_logfont):
6077 * w32reg.c (x_get_string_resource): Silence compiler warnings.
6079 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
6081 * w32fns.c (w32_default_color_map): New function,
6082 extracted from Fw32_default_color_map.
6083 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
6085 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
6087 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
6089 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
6091 * keyboard.c (test_undefined): New function (bug#9751).
6092 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
6094 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
6096 * sysdep.c (init_sys_modes): Fix the check for the controlling
6097 terminal (Bug#6649).
6099 2011-10-20 Eli Zaretskii <eliz@gnu.org>
6101 * dispextern.h (struct bidi_it): New member next_en_type.
6103 * bidi.c (bidi_line_init): Initialize the next_en_type member.
6104 (bidi_resolve_explicit_1): When next_en_pos is valid for the
6105 current character, check also for next_en_type being WEAK_EN.
6106 (bidi_resolve_weak): Don't enter the expensive loop if the current
6107 position is before next_en_pos. Record the bidi type of the first
6108 non-ET, non-BN character we find, in addition to its position.
6109 (bidi_level_of_next_char): Invalidate next_en_type when
6110 next_en_pos is over-stepped.
6112 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
6114 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
6115 * editfns.c: Rewrite current-time-zone so that it invokes
6116 the equivalent of (format-time-string "%Z") to get the time zone name.
6117 This fixes a bug when the time zone name contains characters that
6118 need converting from the system time locale to Emacs internal format.
6119 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
6120 that patch fixed format-time-string to do the conversion, but
6121 I forgot to fix current-time-zone.
6122 (format_time_string): New function, containing most of
6123 what Fformat_time_string used to contain.
6124 (Fformat_time_string): Rewrite in terms of format_time_string.
6125 This doesn't change this function's behavior.
6126 (current-time-zone): Rewrite to use format_time_string.
6127 This fixes the bug reported by Michael Schierl in
6128 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
6129 Jason Rumney's 2007-06-07 change worked around this bug, but
6131 * systime.h (tzname, timezone): Remove no-longer-used declarations.
6133 2011-10-19 Eli Zaretskii <eliz@gnu.org>
6135 * xdisp.c (start_display): If the character at POS is displayed
6136 via a display vector, reset IT->current.dpvec_index to zero.
6137 (try_window_reusing_current_matrix): If a line ends in a display
6138 vector or the next line starts in a display vector, continue
6139 redrawing the window even though the character position of
6140 start_row was reached.
6143 2011-10-18 Chong Yidong <cyd@gnu.org>
6145 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
6146 with nobreak-char-display too.
6148 2011-10-18 Eli Zaretskii <eliz@gnu.org>
6150 Fix part 3 of bug#9771.
6151 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
6152 (bidi_resolve_neutral): Don't enter the expensive loop looking for
6153 non-neutral characters if the current character is a paragraph
6154 separator (a.k.a. Newline). This avoids running the same
6155 expensive loop twice, once when we consume the preceding newline
6156 and the other time when the line actually needs to be displayed.
6157 Avoid the loop when we see neutrals on the base embedding level
6158 following a character whose directionality is the same as the
6159 paragraph's. This avoids running the expensive loop when a line
6160 ends in a long sequence of neutrals, like control characters.
6161 Add assertion against STRONG_AL type. Slightly rearrange code
6162 that determines the type of a neutral given the first non-neutral
6164 (bidi_level_of_next_char): Set next_en_pos to zero when
6165 invalidating its info.
6167 2011-10-17 Eli Zaretskii <eliz@gnu.org>
6169 * xdisp.c (push_display_prop): Determine whether to record string
6170 or buffer position by IT->string, not by IT->method. Allow
6171 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
6172 (move_it_vertically_backward): Don't look for character position
6173 immediately after the newline when in a continuation line.
6176 2011-10-15 Martin Rudalics <rudalics@gmx.at>
6178 * window.c (coordinates_in_window): Rewrite and delabelize
6179 vertical border check. (Bug#5357) (Bug#9618)
6181 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
6183 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
6184 errors in XSetWindowBorder (bug#9310).
6186 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
6188 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
6189 avoid crash when xmalloc overrun checking is enabled.
6191 2011-10-13 Eli Zaretskii <eliz@gnu.org>
6193 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
6194 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
6195 cursor motion with <left> and <right> arrow keys.
6197 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
6198 some callers set that themselves.
6200 2011-10-12 Eli Zaretskii <eliz@gnu.org>
6202 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
6203 display string and the previous row comes from the same string and
6204 is empty. (Bug#9739) (Bug#9738)
6206 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
6208 * doc.c (get_doc_string): Encode file name (bug#9735).
6210 2011-10-12 Eli Zaretskii <eliz@gnu.org>
6212 * bidi.c (bidi_level_of_next_char):
6213 * xdisp.c (get_visually_first_element): Remove old incorrect
6214 comments regarding the Unicode Line Separator character.
6216 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
6218 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
6220 * alloc.c (Fgc_status): Do not access beyond zombies array
6221 boundary if nzombies > MAX_ZOMBIES.
6222 * alloc.c (dump_zombies): Add missing format specifier.
6224 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
6226 * xdisp.c (set_cursor_from_row): Simplify conditionals,
6227 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
6229 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
6230 Some packages use them to denote characters with modifiers.
6232 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
6234 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
6235 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
6236 matching a pp-number. Rename parameter var to var1.
6238 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
6240 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
6242 2011-10-08 Glenn Morris <rgm@gnu.org>
6244 * callint.c (Fcall_interactively): Give a more explicit error for the
6245 'c' case with a non-character input. (Bug#8479)
6247 2011-10-08 Eli Zaretskii <eliz@gnu.org>
6249 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
6251 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
6252 lines that are hscrolled on the left.
6254 * dispnew.c (buffer_posn_from_coords): Account for a possible
6255 presence of header-line. (Bug#4426)
6257 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
6259 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
6260 Don't advertise functionality which we discourage or doesn't work.
6262 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
6264 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
6265 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
6266 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
6267 this makes Emacs dump core during garbage collection on rare
6268 occasions. sizeof is obviously inferior to offsetof here, so
6269 stick with offsetof.
6270 (GC_POINTER_ALIGNMENT): New macro.
6271 (mark_memory): Omit 3rd (offset) arg; caller changed.
6272 Don't assume EMACS_INT alignment is the same as pointer alignment.
6274 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
6276 * keyboard.c (read_key_sequence_remapped): New var.
6277 (read_key_sequence): Compute remapping in the right buffer.
6278 (command_loop_1): Use read_key_sequence's remapping directly.
6280 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
6282 * dired.c (file_name_completion): Don't expand file name.
6283 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
6284 before checking file name handler.
6286 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
6287 they've been requested explicitly (bug#9591).
6289 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
6291 * keymap.c (Fsingle_key_description): Use make_specified_string
6292 instead of build_string to build string from push_key_description.
6295 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
6297 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
6298 This fixes a Y2038 bug on 64-bit hosts.
6299 * buffer.c (reset_buffer):
6300 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
6301 (Fclear_buffer_auto_save_failure):
6302 Use 0, not -1, to represent an unset failure time, since time_t
6303 might not be signed.
6305 Remove dependency on glibc malloc internals.
6306 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6307 Move back here from lisp.h, but with their new implementations.
6308 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
6309 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
6310 * charset.c (charset_table_init): New static var.
6311 (syms_of_charset): Use it instead of xmalloc. This removes a
6312 dependency on glibc malloc internals. See Eli Zaretskii's comment in
6313 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
6314 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6315 Move back to alloc.c.
6316 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
6317 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
6319 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
6321 * nsterm.m (windowDidResize): Call x_set_window_size only when
6322 ns_in_resize is true. Otherwise set pixelwidth/height and
6323 call change_frame_size (Bug#9628).
6325 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
6327 Port --enable-checking=all to Fedora 14 x86-64.
6328 * charset.c (syms_of_charset): Also account for glibc malloc's
6329 internal overhead when calculating the initial malloc maximum.
6331 Port --enable-checking=all to Fedora 14 x86.
6332 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6334 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
6335 (overrun_check_realloc, overrun_check_free):
6336 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
6337 That way, xmalloc returns a properly-aligned pointer even if
6338 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
6339 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
6340 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
6341 into account when calculating the initial malloc maximum.
6342 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6343 Move here from alloc.c, so that charset.c can use it too.
6344 Properly align; the old code wasn't right for common 32-bit hosts
6345 when configured with --enable-checking=all.
6346 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
6347 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
6349 2011-09-29 Eli Zaretskii <eliz@gnu.org>
6351 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
6354 2011-09-28 Eli Zaretskii <eliz@gnu.org>
6356 * xdisp.c (compute_display_string_end): If there's no display
6357 string at CHARPOS, return -1.
6359 * bidi.c (bidi_fetch_char): When compute_display_string_end
6360 returns a negative value, treat the character as a normal
6361 character not covered by a display string. (Bug#9624)
6363 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
6365 * lread.c (Fread_from_string): Fix typo in docstring.
6367 2011-09-27 Eli Zaretskii <eliz@gnu.org>
6369 * xdisp.c (handle_invisible_prop): If invisible text ends on a
6370 newline, reseat the iterator instead of bidi-iterating there one
6371 character at a time. (Bug#9610)
6372 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
6373 TO_CHARPOS if the bidi iterator is at base embedding level.
6375 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
6377 * lread.c (readevalloop): Use correct code for NBSP.
6378 (read1): Likewise. (Bug#9608)
6380 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
6382 * dbusbind.c (Fdbus_register_signal): When service is not
6383 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
6385 2011-09-25 Glenn Morris <rgm@gnu.org>
6387 * buffer.c (truncate-lines): Doc fix.
6389 2011-09-24 Chong Yidong <cyd@stupidchicken.com>

6404 2011-09-24 Eli Zaretskii <eliz@gnu.org>
6406 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
6407 Default value is now t. Doc fix.
6409 * indent.c (Fvertical_motion): Compute and apply the overshoot
6410 logic when moving up, not only when moving down. Fix the
6411 confusing name and values of the it_overshoot_expected variable;
6412 logic changes accordingly. (Bug#9254) (Bug#9549)
6414 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
6415 CHARPOS is covered by a display string which includes newlines.
6416 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
6417 is covered by a display string with embedded newlines.
6419 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
6421 * dbusbind.c (Fdbus_register_signal): Add match rule to
6422 Vdbus_registered_objects_table. (Bug#9581)
6423 (Fdbus_register_method, Vdbus_registered_objects_table):
6426 2011-09-24 Jim Meyering <meyering@redhat.com>
6428 do not ignore write error for any output size
6429 The previous change was incomplete.
6430 While it makes emacs --batch detect the vast majority of stdout
6431 write failures, errors were still ignored whenever the output size is
6432 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
6433 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
6434 && echo FAIL: ignored write error
6435 FAIL: ignored write error
6436 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
6437 && echo FAIL: ignored write error
6438 FAIL: ignored write error
6439 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
6441 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
6443 * emacs.c (Fkill_emacs): In noninteractive mode exit
6444 non-successfully if a write error occurred on stdout. (Bug#9574)
6446 2011-09-21 Eli Zaretskii <eliz@gnu.org>
6448 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
6451 * dispextern.h (struct it): Update the comment documenting what
6454 2011-09-20 Eli Zaretskii <eliz@gnu.org>
6456 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
6457 a display string, extend search for cursor position to end of row.
6458 (find_row_edges): If the row ends in a newline from a display
6459 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
6460 Handle the case of a display string with multiple newlines.
6461 (Fcurrent_bidi_paragraph_direction): Fix search for previous
6462 non-empty line. Fixes confusing cursor motion with arrow keys at
6463 the beginning of a line that starts with whitespace.
6465 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
6467 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
6470 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
6472 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
6475 2011-09-18 Eli Zaretskii <eliz@gnu.org>
6477 * xdisp.c (display_line): Record maximum and minimum buffer
6478 positions even if no glyphs were produced (e.g., by a zero-width
6479 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
6480 buffer positions that will be removed from the glyph row because
6482 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
6483 column is beyond frame width: don't subtract 1 "pixel" when
6484 computing width of the stretch.
6485 (reseat_at_next_visible_line_start): Undo the change made on
6486 2011-09-17 that saved paragraph information and restored it after
6487 the call to `reseat'. (Bug#9545)
6489 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6491 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
6492 and turn window cursor on if cleared (Bug#9415).

6496 * search.c (boyer_moore): Take unibyte characters from pattern
6497 literally. (Bug#9458)
6499 2011-09-18 Eli Zaretskii <eliz@gnu.org>

6503 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
6505 Fix minor problem found by static checking.
6506 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
6507 initialized, to pacify gcc -Wuninitialized.
6509 * fileio.c: Report proper errno when syscall falls.
6510 (Finsert_file_contents): Save and restore errno,
6511 so that report_file_error outputs the correct diagnostic.
6512 (Fwrite_region) [CLASH_DETECTION]: Likewise.
6514 2011-09-18 Eli Zaretskii <eliz@gnu.org>
6516 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
6518 2011-09-17 Eli Zaretskii <eliz@gnu.org>
6520 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
6521 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
6523 2011-09-17 Eli Zaretskii <eliz@gnu.org>
6525 * xdisp.c (reseat_at_next_visible_line_start): Keep information
6526 about the current paragraph and restore it after the call to reseat.
6528 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
6529 (bidi_find_paragraph_start): Search back for paragraph beginning
6530 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
6531 (bidi_move_to_visually_next): Only trigger paragraph-related
6532 computations when the last character is a newline or at EOB, not
6533 just any NEUTRAL_B. (Bug#9470)
6535 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
6536 truncated lines if point is covered by a display string. (Bug#9524)
6538 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
6540 * xselect.c: Relax test for outgoing X longs (Bug#9498).
6541 (cons_to_x_long): New function.
6542 (lisp_data_to_selection_data): Use it. Correct the test for
6543 short-versus-long data; it was negated. Break out of vector
6544 loop, for efficiency, when a long datum is discovered.
6546 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
6548 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
6550 2011-09-16 Eli Zaretskii <eliz@gnu.org>
6552 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
6553 GCC PR/17406) by declaring this function with external scope.
6555 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
6557 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
6558 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
6560 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
6562 * editfns.c (Fformat): Correctly handle text properties on "%%".

6572 of TAB characters in a composition.
6574 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
6576 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
6577 This occurs when processing a multibyte format.
6578 Problem reported by Wolfgang Jenker.
6580 2011-09-15 Johan Bockgård <bojohan@gnu.org>
6582 * xdisp.c (try_cursor_movement): Only check for exact match if
6583 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
6585 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
6587 Remove unused external symbols.
6588 * dispextern.h (calc_pixel_width_or_height): Remove decl.

6590 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
6591 * indent.c (check_display_width):
6592 * w32term.c: Fix comment to match code.
6593 * xterm.c, xterm.h (x_catching_errors): Remove.
6595 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
6597 * xselect.c: Use signed conversions more consistently (Bug#9498).
6598 (selection_data_to_lisp_data): Assume incoming selection data are
6599 signed integers, not unsigned. This is to be consistent with
6600 outgoing selection data, which was modified to use signed integers
6601 in as part of the fix to Bug#9196 in response to Jan D.'s comment
6602 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
6603 expects long, not unsigned long.
6605 2011-09-14 Eli Zaretskii <eliz@gnu.org>
6607 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
6608 computation of loop end. Reported by Johan Bockgård
6611 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
6613 * frame.c (Fother_visible_frames_p): Function deleted.
6615 2011-09-12 Eli Zaretskii <eliz@gnu.org>
6617 * indent.c (compute_motion): Process display vector front to back
6618 rather than the other way around. (Bug#2496)
6620 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
6622 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
6624 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
6626 * minibuf.c (Fread_from_minibuffer): Doc fix.
6628 2011-09-11 Eli Zaretskii <eliz@gnu.org>
6630 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
6631 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
6633 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
6635 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
6636 value for non-existent files.
6638 2011-09-11 Eli Zaretskii <eliz@gnu.org>
6640 * fileio.c (Finsert_file_contents): If the file cannot be opened,
6641 set its "size" to -1. This will set the modtime_size field of
6642 the corresponding buffer to -1, which is what
6643 verify-visited-file-modtime expects for files that do not exist.
6646 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
6648 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
6650 * lisp.h: ... from here. push_key_description is no longer
6651 defined in keyboard.c, so its declaration should not be in
6652 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
6653 logically belongs with push_key_description.
6655 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
6657 * buffer.h: Include <sys/types.h> instead of <time.h>.
6658 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
6659 Problem reported by Herbert J. Skuhra.
6661 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
6663 * xml.c (parse_region): Make the parsing work for
6664 non-comment-starting XML files again (bug#9144).
6666 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
6668 * image.c (gif_load): Fix calculation of bottom and right corner.
6671 2011-09-10 Eli Zaretskii <eliz@gnu.org>
6673 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
6674 redisplay in small windows.
6676 2011-09-09 Eli Zaretskii <eliz@gnu.org>
6678 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
6680 2011-09-08 Martin Rudalics <rudalics@gmx.at>
6682 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
6683 Operate on live windows only.
6685 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
6687 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
6689 2011-09-07 Eli Zaretskii <eliz@gnu.org>
6691 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
6692 only under bidi iteration.
6694 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
6696 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
6698 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
6700 isnan: Fix porting problem to Solaris 10 with bundled gcc.
6701 Without this fix, the command to link temacs failed due to an
6702 undefined symbol __builtin_isnan. This is because
6703 /usr/include/iso/math_c99.h #defines isnan(x) to
6704 __builtin_isnan(x), but the bundled gcc, which identifies itself
6705 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
6707 * floatfns.c (isnan): #undef, and then #define to a clone of
6709 (Fisnan): Always define, since it's always available now.
6710 (syms_of_floatfns): Always define isnan at the Lisp level.
6712 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
6714 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
6716 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
6718 * fileio.c: Fix bugs with large file offsets (Bug#9428).
6719 The previous code assumed that file offsets (off_t values) fit in
6720 EMACS_INT variables, which is not true on typical 32-bit hosts.
6721 The code messed up by falsely reporting buffer overflow in cases
6722 such as (insert-file-contents "big" nil 1 2) into an empty buffer
6723 when "big" contains more than 2**29 bytes, even though this
6724 inserts just one byte and does not overflow the buffer.
6725 (Finsert_file_contents): Store file offsets as off_t
6726 values, not as EMACS_INT values. Check for overflow when
6727 converting between EMACS_INT and off_t. When checking for
6728 buffer overflow or for overlap, take the offsets into account.
6729 Don't use EMACS_INT for small values where int suffices.
6730 When checking for overlap, fix a typo: ZV was used where
6731 ZV_BYTE was intended.
6732 (Fwrite_region): Don't assume off_t fits into 'long'.
6733 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
6735 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
6737 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
6739 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
6741 sprintf-related integer and memory overflow issues (Bug#9412).
6743 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
6744 (esprintf, exprintf, evxprintf): New functions.
6745 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
6746 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
6747 (modify_event_symbol): Do not assume that the length of
6748 name_alist_or_stem is safe to alloca and fits in int.
6749 (Fexecute_extended_command): Likewise for function name and binding.
6750 (Frecursion_depth): Wrap around reliably on integer overflow.
6751 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
6752 since some callers pass EMACS_INT values.
6753 (Fsingle_key_description): Don't crash if symbol name contains more
6754 than MAX_ALLOCA bytes.
6755 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
6756 (get_minibuffer): Arg is now EMACS_INT, not int.
6757 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
6758 (esprintf, exprintf, evxprintf): New decls.
6759 * window.h (command_loop_level, minibuf_level): Reflect API changes.
6761 * dbusbind.c (signature_cat): New function.
6762 (xd_signature, Fdbus_register_signal):
6763 Do not overrun buffer; instead, report string overflow.
6765 * dispnew.c (add_window_display_history): Don't overrun buffer.
6766 Truncate instead; this is OK since it's just a log.
6768 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
6769 even if the time zone offset is outlandishly large.
6770 Don't mishandle offset == INT_MIN.
6772 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
6773 when creating daemon; the previous buffer-overflow check was incorrect.
6775 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
6776 which has the guts of the old verror function.
6778 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
6779 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
6781 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
6782 (font_unparse_xlfd): Don't blindly alloca long strings.
6783 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
6784 fits in int, when using sprintf. Use single snprintf to count
6785 length of string rather than counting it via multiple sprintfs;
6786 that's simpler and more reliable.
6787 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
6788 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
6789 sprintf, in case result does not fit in int.
6791 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
6792 (fontset_from_font): Print it.
6794 * frame.c (tty_frame_count): Now printmax_t, not int.
6795 (make_terminal_frame, set_term_frame_name): Print it.
6796 (x_report_frame_params): In X, window IDs are unsigned long,
6797 not signed long, so print them as unsigned.
6798 (validate_x_resource_name): Check for implausibly long names,
6799 and don't assume name length fits in 'int'.
6800 (x_get_resource_string): Don't blindly alloca invocation name;
6801 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
6804 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
6805 (xg_check_special_colors, xg_set_geometry):
6806 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
6808 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
6809 Use esprintf, not sprintf, in case result does not fit in int.
6811 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
6812 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
6813 it as a large positive number.
6814 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
6815 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
6817 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
6818 in case result does not fit in int.
6820 * print.c (float_to_string): Detect width overflow more reliably.
6821 (print_object): Make sprintf buffer a bit bigger, to avoid potential
6822 buffer overrun. Don't assume list length fits in 'int'. Treat
6823 print length of 0 as 0, not as infinity; to be consistent with other
6824 uses of print length in this function. Don't overflow print length
6825 index. Don't assume hash table size fits in 'long', or that
6826 vectorlike size fits in 'unsigned long'.
6828 * process.c (make_process): Use printmax_t, not int, to format
6829 process-name gensyms.
6831 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
6833 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
6834 to avoid potential buffer overrun.
6836 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
6837 if X resource line is longer than 512 bytes.
6839 * xfns.c (x_window): Make sprintf buffer a bit bigger
6840 to avoid potential buffer overrun.
6842 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
6844 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
6846 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
6848 Integer overflow fixes for scrolling, etc.
6849 Without these, Emacs silently mishandles large integers sometimes.
6850 For example, "C-u 4294967297 M-x recenter" was treated as if
6851 it were "C-u 1 M-x recenter" on a typical 64-bit host.
6853 * xdisp.c (try_window_id): Check Emacs fixnum range before
6854 converting to 'int'.
6856 * window.c (window_scroll_line_based, Frecenter):
6857 Check that an Emacs fixnum is in range before assigning it to 'int'.
6858 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
6859 values converted from Emacs fixnums.
6860 (Frecenter): Don't wrap around a line count if it is out of 'int'
6861 range; instead, treat it as an extreme value.
6862 (Fset_window_configuration, compare_window_configurations):
6863 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
6865 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
6866 that can exceed INT_MAX. Check that EMACS_INT value is in range
6867 before assigning it to the (possibly-narrower) index.
6868 (match_limit): Don't assume that a fixnum can fit in 'int'.
6870 * print.c (print_object): Use ptrdiff_t, not int, for index that can
6873 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
6874 (Fvertical_motion): Don't wrap around LINES values that don't fit
6875 in 'int'. Instead, treat them as extreme values. This is good
6876 enough for windows, which can't have more than INT_MAX lines anyway.
6878 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
6880 * Require libxml/parser.h to avoid compilation warning.
6882 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
6884 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
6885 since this reportedly can destroy thread storage.
6887 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
6889 * syntax.c (find_defun_start): Update all cache variables if
6890 exiting early (Bug#9401).
6892 2011-08-30 Eli Zaretskii <eliz@gnu.org>
6894 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
6896 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
6897 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
6898 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
6900 * term.c (tty_append_glyph): New function.
6901 (produce_stretch_glyph): Static function and its prototype deleted.
6903 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
6906 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
6908 * image.c (parse_image_spec): Check for nonnegative, not for positive,
6909 when checking :margin (Bug#9390).
6910 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
6911 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
6912 so that the name doesn't mislead. All uses changed.
6914 2011-08-28 Johan Bockgård <bojohan@gnu.org>
6916 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
6919 2011-08-27 Eli Zaretskii <eliz@gnu.org>
6921 * xdisp.c (move_it_to): Don't bail out early when reaching
6922 position beyond to_charpos, if we are scanning backwards.
6923 (move_it_vertically_backward): When DY == 0, make sure we get to
6924 the first character in the line after the newline.
6926 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
6928 * ccl.c: Improve and simplify overflow checking (Bug#9196).
6929 (ccl_driver): Do not generate an out-of-range pointer.
6930 (Fccl_execute_on_string): Remove unnecessary check for
6931 integer overflow, noted by Stefan Monnier in
6932 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
6933 Remove a FIXME that didn't need fixing.
6934 Simplify the newly-introduced buffer reallocation code.
6936 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
6938 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
6940 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
6942 Integer and memory overflow issues (Bug#9196).
6944 * doc.c (get_doc_string): Rework so that
6945 get_doc_string_buffer_size is the actual buffer size, rather than
6946 being 1 less than the actual buffer size; this makes xpalloc more
6949 * image.c (x_allocate_bitmap_record, cache_image):
6950 * xselect.c (Fx_register_dnd_atom):
6951 Simplify previous changes by using xpalloc.
6953 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
6954 since either will do and ptrdiff_t is convenient with xpalloc.
6956 * charset.c (charset_table_size)
6957 (struct charset_sort_data.priority): Now ptrdiff_t.
6958 (charset_compare): Don't overflow if priorities differ greatly.
6959 (Fsort_charsets): Don't assume list length fits in int.
6960 Check for size-calculation overflow when allocating sort data.
6961 (syms_of_charset): Allocate an initial charset table that is
6962 just under 64 KiB, to avoid problems with glibc malloc and mmap.
6964 * cmds.c (internal_self_insert): Check for size-calculation overflow.
6966 * composite.h (struct composition.glyph_len): Now int, not unsigned.
6967 The actual value is always <= INT_MAX, and leaving it unsigned made
6968 overflow checking harder.
6970 * dispextern.h (struct glyph_matrix.rows_allocated)
6971 (struct face_cache.size): Now ptrdiff_t, for convenience in use
6972 with xpalloc. The values are still always <= INT_MAX.
6974 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
6976 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
6977 (SAFE_NALLOCA): New macro.
6979 * region-cache.c (struct boundary.pos, find_cache_boundary)
6980 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
6981 (set_cache_region, invalidate_region_cache)
6982 (revalidate_region_cache, know_region_cache, region_cache_forward)
6983 (region_cache_backward, pp_cache):
6984 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
6985 so that ptrdiff_t * can be passed to xpalloc.
6986 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
6987 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
6988 (pp_cache): Don't assume cache_len fits in int.
6989 * region-cache.h: Adjust extern decls to match.
6991 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
6992 EMACS_INT, since either will do, for xpalloc.
6994 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
6995 (xnmalloc, xnrealloc, xpalloc): New functions.
6997 * bidi.c (bidi_shelve_header_size): New constant.
6998 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
6999 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
7001 * bidi.c (bidi_cache_shrink):
7002 * buffer.c (overlays_at, overlays_in, record_overlay_string)
7004 Don't update size of array until after memory allocation succeeds,
7005 because xmalloc/xrealloc may not return.
7006 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
7007 now that we have proper integer overflow checking.
7008 (record_overlay_string, overlay_strings): Catch overflows when
7009 calculating size of overlay_str_buf.
7011 * callproc.c (Fcall_process): Check for size overflow when
7012 calculating size of args2.
7013 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
7014 Normally we prefer signed values, but sticking with ptrdiff_t would
7015 require adding more-complicated checks.
7017 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
7018 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
7019 Redo buffer-overflow calculations to avoid integer overflow.
7020 Add a FIXME comment where memory seems to be over-allocated.
7022 * character.c (Fstring): Check for size-calculation overflow.
7024 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
7025 unnecessary integer overflow. Check for size overflow.
7026 (encode_coding_object): Don't update size until xmalloc succeeds.
7028 * composite.c (get_composition_id): Check for overflow in glyph
7029 length calculations.
7031 Integer and memory overflow fixes for display code.
7032 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
7033 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
7034 (scrolling_window): Check for overflow in size calculations.
7035 (line_draw_cost, realloc_glyph_pool, add_row_entry):

7046 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
7047 (get_doc_string): Check for size calculation overflow.
7048 Don't update size until allocation succeeds.
7049 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
7050 EMACS_INT, where ptrdiff_t will do.
7051 (Fsubstitute_command_keys): Check for string overflow.
7053 * editfns.c (set_time_zone_rule): Don't assume environment length
7055 (message_length): Now ptrdiff_t, not int.
7056 (Fmessage_box): Don't update size until allocation succeeds.
7057 Don't assume message length fits in int.
7058 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
7060 * emacs.c (main): Do not reallocate argv, since there is a null at
7061 the end that can be overwritten, and this way there's no need to
7062 worry about size-calculation overflow.
7063 (sort_args): Check for size-calculation overflow.
7065 * eval.c (init_eval_once, grow_specpdl): Don't update size until
7067 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
7069 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
7070 (x_set_scroll_bar_width, x_figure_window_size):
7071 Check for integer overflow.
7072 (x_set_alpha): Do not assume XINT fits in int.
7074 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
7075 This is for the members text_lines, text_cols, total_lines, total_cols,
7076 where the system imposes an 'int' limit.
7078 * fringe.c (Fdefine_fringe_bitmap):
7079 Don't update size until alloc works.
7081 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
7082 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
7084 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
7085 Check for size-calculation overflow.
7086 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
7087 do, as we prefer signed integers.
7088 (id_to_widget.max_size, id_to_widget.used)
7089 (xg_store_widget_in_map, xg_remove_widget_from_map)
7090 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
7091 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
7092 Use and return ptrdiff_t, not int.
7093 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
7094 * gtkutil.h: Change prototypes to match the above.
7096 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
7097 are duplicate now that they've been promoted to lisp.h.
7098 (x_allocate_bitmap_record, x_alloc_image_color)
7099 (make_image_cache, cache_image, xpm_load):
7100 Don't update size until alloc is done.

7110 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
7111 Use ptrdiff_t, not int, to count maps.
7112 (read_char_minibuf_menu_prompt): Check for overflow in size
7113 calculations. Don't update size until allocation succeeds.

7125 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.
7127 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
7128 Now ptrdiff_t, not int.
7129 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.

7140 * search.c (Freplace_match): Check for size calculation overflow.
7141 (Fset_match_data): Don't assume list lengths fit in 'int'.
7143 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
7144 for command line length. Do not attempt to address one before the
7145 beginning of an array, as that's not portable.

7148 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
7150 (encode_terminal_code, calculate_costs): Check for size
7151 calculation overflow.

7153 table lengths and related sizes. Don't update size until alloc
7154 done. Redo calculations to avoid overflow.
7155 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
7157 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of

7173 Use ptrdiff_t, not int, for sizes.
7174 (Finternal_make_lisp_face, cache_face):
7175 Check for size calculation overflow.
7176 (cache_face): Treat size calculation overflows as if they were
7177 memory exhaustion (the usual treatment), rather than aborting.
7179 * xfns.c (x_encode_text, x_set_name_internal)
7180 (Fx_change_window_property): Use ptrdiff_t, not int, to count
7181 sizes, since they can exceed INT_MAX in size. Check for size

7185 (xg_select): Check for size calculation overflow.
7186 Don't update size until alloc done.
7188 * xrdb.c (get_environ_db): Don't assume path length fits in int,
7189 as sprintf is limited to int lengths.
7191 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
7192 (X_LONG_MIN): New macros.
7193 Use them to make the following changes clearer.
7194 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
7195 This change doesn't affect the value now, but it may help remind
7196 future maintainers not to raise the value too much later.
7197 (SELECTION_QUANTUM): Remove, replacing with ...
7198 (selection_quantum): ... new function, which avoids overflow.
7200 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
7201 assumption that selection length fits in 'int'.

7204 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
7205 (lisp_data_to_selection_data, clean_local_selection_data):

7209 Redo calculations to avoid overflow.
7210 (x_reply_selection_request): When sending hint, ceiling it at
7211 X_LONG_MAX rather than relying on wraparound overflow to send

7214 (lisp_data_to_selection_data, x_property_data_to_lisp):
7215 Check for size-calculation overflow.

7218 Don't store size until memory allocation succeeds.
7219 (x_get_window_property): Plug memory leak on memory exhaustion.
7220 Don't double-block input; malloc is safe here. Don't assume 2**34
7221 - 4 fits in unsigned long. Add an xassert to check
7222 XGetWindowProperty overflow. Be more careful about overflow
7223 calculations, and distinguish size from memory overflow better.
7224 (receive_incremental_selection): When tracing, don't assume
7225 unsigned int is less than INT_MAX.
7226 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
7227 harmful) conversions of unsigned short to int.
7228 (lisp_data_to_selection_data): Don't assume that integers
7229 in the range -65535 through -1 fit in an X unsigned short.
7230 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
7231 result parameters unless successful. Rely on cons_to_unsigned
7232 to report problems with elements; the old code wasn't right anyway.
7233 (x_check_property_data): Check for int overflow; we cannot use
7234 a wider type due to X limits.
7235 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

7266 * image.c (xpm_get_color_table_h):
7267 * lisp.h (hash_lookup, hash_put):
7268 * minibuf.c (Ftest_completion):
7269 Use ptrdiff_t for hash table indexes, not int (which is too
7270 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
7271 32-bit --with-wide-int hosts).
7273 * charset.c (Fdefine_charset_internal): Check for integer overflow.
7274 Add a FIXME comment about memory leaks.

7279 * character.h (CHAR_WIDTH):
7280 * indent.c (MULTIBYTE_BYTES_WIDTH):
7281 Use sanitize_char_width to avoid undefined and/or bad behavior
7282 with outlandish widths.
7283 * character.h (sanitize_tab_width): Rename from sanitize_width,
7284 now that we have two such functions. All uses changed.
7285 (sanitize_char_width): New inline function.
7287 Don't assume that tab-width fits in int.
7288 * character.h (sanitize_width): New inline function.
7289 (SANE_TAB_WIDTH): New macro.

7304 (x_send_scroll_bar_event): Likewise. Check that the size does not
7305 exceed limits imposed by XClientMessageEvent, as well as the usual
7306 ptrdiff_t and size_t limits.
7308 * keyboard.c: Overflow, signedness and related fixes.
7309 (make_lispy_movement): Use same integer type in forward decl
7310 that is used in the definition.
7311 (read_key_sequence, keyremap_step):
7312 Change bufsize argument back to int, undoing my 2011-03-30 change.
7313 We prefer signed types, and int is wide enough here.
7314 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
7315 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
7316 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
7317 length, not size_t. Use ptrdiff_t for index, not int.
7318 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
7319 possibility of integer overflow.
7321 Overflow, signedness and related fixes for images.
7323 * dispextern.h (struct it.stack[0].u.image.image_id)
7324 (struct_it.image_id, struct image.id, struct image_cache.size)

7330 * nsmenu.m (update_frame_tool_bar):
7331 * xdisp.c (calc_pixel_width_or_height):
7332 * xfns.c (image_cache_refcount):

7334 on typical 64-bit hosts.
7336 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
7337 (x_bitmap_pixmap, x_create_x_image_and_pixmap):
7338 Omit unnecessary casts to int.

7340 when the callers expect that.
7341 (image_ascent): Redo ascent calculation to avoid int overflow.
7342 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
7343 (lookup_image): Remove unnecessary tests.
7344 (xbm_image_p): Locals are now of int, not EMACS_INT,
7345 since parse_image_check makes sure they fit into int.
7346 (png_load, gif_load, svg_load_image):
7347 Prefer int to unsigned where either will do.
7348 (tiff_handler): New function, combining the cores of the
7349 old tiff_error_handler and tiff_warning_handler.
7350 This function is rewritten to use vsnprintf and thereby avoid
7351 stack buffer overflows. It uses only the features of vsnprintf
7352 that are common to both POSIX and native Microsoft.
7353 (tiff_error_handler, tiff_warning_handler): Use it.
7354 (tiff_load, gif_load, imagemagick_load_image):
7355 Don't assume :index value fits in 'int'.
7356 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
7357 (imagemagick_load_image): Check that crop parameters fit into
7358 the integer types that MagickCropImage accepts. Don't assume
7359 Vimagemagick_render_type has a nonnegative value. Don't assume
7360 size_t fits in 'long'.
7361 (gs_load): Use printmax_t to print the widest integers possible.
7362 Check for integer overflow when computing image height and width.
7364 2011-08-26 Eli Zaretskii <eliz@gnu.org>
7366 * xdisp.c (redisplay_window): Don't force window start if point

7374 handle_single_display_spec, not just 1 or zero.
7375 (handle_single_display_spec): If the display spec is of the form
7376 `(space ...)', and specifies display in the text area, return 2
7378 (try_cursor_movement): Check for the need to scroll more
7379 accurately, and prefer exact match for point under bidi.
7380 Don't advance `row' beyond the last row of the window.
7382 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
7383 into disp_prop; all users changed.
7385 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
7386 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
7387 for the text covered by the display property.
7389 2011-08-25 Chong Yidong <cyd@stupidchicken.com>
7391 * buffer.c (Fbury_buffer_internal): Rename from Funrecord_buffer.

7397 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
7398 buffers, return left-to-right.
7399 (set_cursor_from_row): Consider candidate row a win if its glyph
7400 represents a newline and point is on that newline. Fixes cursor
7401 positioning on the newline at EOL of R2L text within L2R
7402 paragraph, and vice versa.
7403 (try_cursor_movement): Check continued rows, in addition to
7404 continuation rows. Fixes unwarranted scroll when point enters a
7405 continued line of R2L text within an L2R paragraph, or vice versa.
7406 (cursor_row_p): Consider the case of point being equal to
7407 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
7408 from the end of a short line to the beginning of a continued line
7409 of R2L text within L2R paragraph.
7410 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
7411 composed characters.
7413 * bidi.c (bidi_check_type): Use xassert.
7414 (bidi_cache_iterator_state): Update the disp_pos and disp_prop_p
7417 2011-08-23 Eli Zaretskii <eliz@gnu.org>
7419 * bidi.c (bidi_get_type): Abort if we get zero as the bidi type of
7422 2011-08-23 Chong Yidong <cyd@stupidchicken.com>
7424 * nsfont.m (ns_otf_to_script): Fix typo.
7426 2011-08-22 Kenichi Handa <handa@m17n.org>
7428 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
7429 extra slot even if the purpose is char-code-property-table.
7431 2011-08-23 Eli Zaretskii <eliz@gnu.org>
7433 * xdisp.c (redisplay_window): When computing centering_position,
7434 account for the height of the header line. (Bug#8874)
7436 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
7437 instead of CHAR_TO_BYTE. Fixes a crash when a completion
7438 candidate is selected by the mouse, and that candidate has a
7439 composed character under the mouse.
7441 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
7442 coordinates reported by pos-visible-in-window-p for a composed
7443 character in column zero.
7445 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>
7447 * cmds.c (Fself_insert_command): Mention post-self-insert-hook.
7449 2011-08-22 Eli Zaretskii <eliz@gnu.org>
7451 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
7452 consider it a hit if to_charpos is anywhere in the range of the
7453 composed buffer positions.
7455 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
7457 * image.c (gif_load): Don't assume that each subimage has the same
7458 dimensions as the base image. Handle disposal method that is
7459 "undefined" by the gif spec (Bug#9335).
7461 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
7463 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
7464 (Fcondition_case): Document `debug' symbol in error handler.
7466 2011-08-19 Eli Zaretskii <eliz@gnu.org>
7468 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
7469 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
7470 from an Org mode buffer to a Speedbar frame.
7472 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
7473 a composition, take its buffer position from IT->cmp_it.charpos.
7474 Fixes cursor positioning at the beginning of a line that begins
7475 with a composed character.
7477 2011-08-18 Eli Zaretskii <eliz@gnu.org>
7479 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
7480 character bidirectional type, use STRONG_L instead. Fixes crashes
7481 in a buffer produced by `describe-categories'.
7483 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
7484 members before the level stack, so they would be saved and
7485 restored when copying iterator state. Fixes incorrect reordering
7486 around TABs covered by display properties.
7488 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
7490 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

7560 * xdisp.c (move_it_in_display_line_to): Don't invoke
7561 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
7562 ppos_it. Fixes vertical cursor motion when line beginning is
7563 covered by an image. (Bug#9296)
7565 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
7567 * nsterm.h (ns_run_ascript): Declare.

7571 (ns_run_ascript): New function.
7572 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
7573 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
7574 the event loop. Get status from as_status (Bug#7276).
7576 * nsterm.m (sendEvent): If event is NSApplicationDefined and
7577 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
7578 the event loop (Bug#7276).

7604 (Fnetwork_interface_list): Allocate in increments of bytes instead
7605 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
7606 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
7608 (struct ifflag_def): notrailers is smart on OSX.
7609 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
7610 Get hardware address with getifaddrs if available.
7612 2011-08-12 Eli Zaretskii <eliz@gnu.org>
7614 * xdisp.c (iterate_out_of_display_property): xassert that
7615 IT->position is set to within IT->object's boundaries. Break from
7616 the loop as soon as EOB is reached; avoids infloops in redisplay
7617 when IT->position is set up wrongly due to some bug.
7618 Set IT->current to match the bidi iterator unconditionally.
7619 (push_display_prop): Allow GET_FROM_STRING as IT->method on
7620 entry. Force push_it to save on the stack the current
7621 buffer/string position, to be restored by pop_it. Fix flags in
7622 the iterator structure wrt the object coming from a display
7623 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
7624 properties. (Bug#9284)
7626 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
7628 * fontset.c (fontset_get_font_group): Add proper type checks.

7641 no-display-properties-and-no-overlays under bidi display.
7642 Set disp_pos in the bidi iterator to avoid searches for display
7643 properties and overlays.
7645 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
7647 * editfns.c (Fset_time_zone_rule): Document relationship with the

7656 restore_point_unwind (Bug#5984).
7658 2011-08-07 Juri Linkov <juri@jurta.org>
7660 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
7661 to show the arg `TIME' instead of `TIMEVAL'.

7667 longlines-mode. (Bug#9254)
7668 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
7669 word-wrap under bidirectional display. (Bug#9224)
7671 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
7672 is non-zero, even if the data buffer is NULL. Fixes a crash in
7673 vertical-motion with longlines-mode. (Bug#9254)
7675 2011-08-05 Eli Zaretskii <eliz@gnu.org>
7677 * bidi.c <bidi_cache_total_alloc>: Now static.

7680 * xdisp.c (display_line): Release buffer allocated for shelved bidi
7683 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
7684 amount allocated this far in `bidi_cache_total_alloc'.
7685 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
7686 non-zero, only free the data buffer without restoring the cache
7687 contents. All callers changed.
7689 * dispextern.h (bidi_unshelve_cache): Update prototype.
7691 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
7692 (move_it_in_display_line, move_it_to)
7693 (move_it_vertically_backward, move_it_by_lines): Replace the call
7694 to xfree to an equivalent call to bidi_unshelve_cache.
7695 (move_it_in_display_line_to): Fix logic of returning
7696 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
7698 2011-08-05 Eli Zaretskii <eliz@gnu.org>
7700 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that

7774 BIDI_IT_PREV, and store into it the state of the bidi iterator had
7776 (reseat_at_next_visible_line_start): Use the bidi iterator state
7777 returned by forward_to_next_line_start to restore the state of
7778 it->bidi_it after backing up to previous newline. (Bug#9212)

7783 (re_exec): Fix return type.
7784 (regexec): Fix type of `ret'. (Bug#9203)
7786 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
7788 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
7789 This is needed if max-image-size is a floating-point number.
7791 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
7793 * print.c (print_object): Print empty symbol as ##.
7795 * lread.c (read1): Read ## as empty symbol.
7797 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
7799 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
7800 setting frame foreground color (Bug#9175).
7801 (x_set_background_color): Likewise.
7803 * nsmenu.m (-setText): Size tooltip dimensions precisely to
7804 contents (Bug#9176).
7805 (EmacsTooltip -init): Remove bezels and add shadows to
7808 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
7809 or scroll bar (Bug#8470).
7811 * nsfont.m (nsfont_open): Remove assignment to voffset and
7812 unnecessary vars hshink, expand, hd, full_height, min_height.
7813 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
7815 * nsterm.h (nsfont_info): Remove voffset field.
7817 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
7819 Implement strike-through and overline on NextStep (Bug#8863).
7821 * nsfont.m (nsfont_open): Use underline position provided by font,
7822 instead of hard-coded value of 2.
7823 (nsfont_draw): Call ns_draw_text_decoration instead.
7825 * nsterm.h: Add declaration for ns_draw_text_decoration.
7827 * nsterm.m (ns_draw_text_decoration): New function for drawing
7828 underline, overline, and strike-through.
7829 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
7830 ns_draw_text_decoration. Change treatment of cursor drawing to
7831 accommodate underlining, etc.
7833 2011-07-28 Eli Zaretskii <eliz@gnu.org>
7835 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
7838 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
7840 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
7841 Without this fix, if a signal arrives just after memory fills up,
7842 'malloc' might be invoked reentrantly.
7844 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
7845 In other words, assume that every image size is allowed, on non-X
7846 hosts. This assumption is probably wrong, but it lets Emacs compile.
7848 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
7850 * regex.c (re_iswctype): Convert return values to boolean.
7852 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
7854 * xdisp.c (compute_display_string_pos): Don't use cached display
7855 string position if the buffer had its restriction changed.
7858 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
7860 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
7862 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
7864 Integer signedness and overflow and related fixes. (Bug#9079)
7866 * bidi.c: Integer size and overflow fixes.
7867 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
7868 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
7869 (bidi_cache_find_level_change, bidi_cache_ensure_space)
7870 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
7871 (bidi_find_other_level_edge):
7872 Use ptrdiff_t instead of EMACS_INT where either will do.
7873 This works better on 32-bit hosts configured --with-wide-int.
7874 (bidi_cache_ensure_space): Check for size-calculation overflow.
7875 Use % rather than repeated addition, for better worst-case speed.
7876 Don't set bidi_cache_size until after xrealloc returns, because it
7878 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
7879 (bidi_cache_ensure_space): Also check that the bidi cache size
7880 does not exceed that of the largest Lisp string or buffer. See Eli
7881 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
7883 * alloc.c (__malloc_size_t): Remove.
7884 All uses replaced by size_t. See Andreas Schwab's note
7885 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
7887 * image.c: Improve checking for integer overflow.
7888 (check_image_size): Assume that f is nonnull, since
7889 it is always nonnull in practice. This is one less thing to
7890 worry about when checking for integer overflow later.
7891 (x_check_image_size): New function, which checks for integer
7892 overflow issues inside X.
7893 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
7894 This removes the need for a memory_full check.
7895 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
7896 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
7897 (xbm_read_bitmap_data): Change locals back to 'int', since
7898 their values must fit in 'int'.
7899 (xpm_load_image, png_load, tiff_load):
7900 Invoke x_create_x_image_and_pixmap earlier,
7901 to avoid much needless work if the image is too large.
7902 (tiff_load): Treat overly large images as if
7903 x_create_x_image_and_pixmap failed, not as malloc failures.
7904 (gs_load): Use x_check_image_size.
7906 * gtkutil.c: Omit integer casts.
7907 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
7908 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
7910 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
7912 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
7913 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
7914 would wrongly return t on a 64-bit host.
7916 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
7917 The plain *_OVERFLOW macros run afoul of GCC bug 49705
7918 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
7919 and therefore cause GCC to emit a bogus diagnostic in some cases.
7921 * image.c: Integer signedness and overflow and related fixes.
7922 This is not an exhaustive set of fixes, but it's time to
7923 record what I've got.
7924 (lookup_pixel_color, check_image_size): Remove redundant decls.
7925 (check_image_size): Don't assume that arbitrary EMACS_INT values
7926 fit in 'int', or that arbitrary 'double' values fit in 'int'.
7927 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
7928 (tiff_load, imagemagick_load_image):
7929 Check for overflow in size calculations.
7930 (x_create_x_image_and_pixmap): Remove unnecessary test for
7931 xmalloc returning NULL; that can't happen.
7932 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
7933 (xpm_color_bucket): Use better integer hashing function.
7934 (xpm_cache_color): Don't possibly over-allocate memory.
7935 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
7936 (gif_memory_source):
7937 Use ptrdiff_t, not int or size_t, to record sizes.
7938 (png_load): Don't assume values greater than 2**31 fit in 'int'.
7939 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
7940 either works, as we prefer signed integers.
7941 (tiff_read_from_memory, tiff_write_from_memory):
7942 Return tsize_t, not size_t, since that's what the TIFF API wants.
7943 (tiff_read_from_memory): Don't fail simply because the read would
7944 go past EOF; instead, return a short read.
7945 (tiff_load): Omit no-longer-needed casts.
7946 (Fimagemagick_types): Don't assume size fits into 'int'.
7948 Improve hashing quality when configured --with-wide-int.
7949 * fns.c (hash_string): New function, taken from sxhash_string.
7950 Do not discard information about ASCII character case; this
7951 discarding is no longer needed.
7952 (sxhash-string): Use it. Change sig to match it. Caller changed.
7953 * lisp.h: Declare it.
7954 * lread.c (hash_string): Remove, since we now use fns.c's version.
7955 The fns.c version returns a wider integer if --with-wide-int is
7956 specified, so this should help the quality of the hashing a bit.
7958 * emacs.c: Integer overflow minor fix.
7959 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
7960 Define only if GNU_LINUX.
7961 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
7963 * dispnew.c: Integer signedness and overflow fixes.
7964 Remove unnecessary forward decls, that were a maintenance hassle.
7965 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
7967 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
7968 (scrolling_window): Use ptrdiff_t, not int, for byte count.
7969 (prepare_desired_row, line_draw_cost):
7970 Use int, not unsigned, where either works.
7971 (save_current_matrix, restore_current_matrix):
7972 Use ptrdiff_t, not size_t, where either works.
7973 (init_display): Check for overflow more accurately, and without
7974 relying on undefined behavior.
7976 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
7977 Remove, replacing with the new symbols in lisp.h. All uses changed.
7978 * fileio.c (make_temp_name):
7979 * filelock.c (lock_file_1, lock_file):
7980 * xdisp.c (message_dolog):
7981 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
7982 Use pMd etc. instead.
7983 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
7984 replacing the pWIDE etc. symbols removed from editfns.c.
7986 * keyboard.h (num_input_events): Now uintmax_t.
7987 This is (very slightly) less likely to mess up due to wraparound.
7990 * buffer.c: Integer signedness fixes.
7991 (alloc_buffer_text, enlarge_buffer_text):
7992 Use ptrdiff_t rather than size_t when either will do, as we prefer
7995 * alloc.c: Integer signedness and overflow fixes.
7996 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
7997 (__malloc_size_t): Default to size_t, not to int.
7998 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
7999 (Fgarbage_collect, mark_object_loop_halt, mark_object):
8000 Prefer ptrdiff_t to size_t when either would do, as we prefer
8002 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
8003 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
8004 Now const. Initialize with values that are in range even if char
8006 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
8007 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
8008 These functions do the right thing with sizes > 2**32.
8009 (check_depth): Now ptrdiff_t, not int.
8010 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
8011 Adjust to new way of storing sizes. Check for size overflow bugs
8013 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
8014 slightly wrong anyway, as it missed one instance of
8015 XMALLOC_OVERRUN_CHECK_OVERHEAD.
8016 (refill_memory_reserve): Omit needless cast to size_t.
8017 (mark_object_loop_halt): Mark as externally visible.
8019 * xselect.c: Integer signedness and overflow fixes.
8020 (Fx_register_dnd_atom, x_handle_dnd_message):
8021 Use ptrdiff_t, not size_t, since we prefer signed.
8022 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
8023 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
8024 x_dnd_atoms_size and x_dnd_atoms_length.
8026 * doprnt.c: Prefer signed to unsigned when either works.
8028 * doprnt.c (doprnt):
8030 * xdisp.c (vmessage):
8031 Use ptrdiff_t, not size_t, when using or implementing doprnt,
8032 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
8033 prefer signed arithmetic to avoid comparison confusion.
8034 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
8035 but is a bit tricky.
8037 Assume freestanding C89 headers, string.h, stdlib.h.
8038 * data.c, doprnt.c, floatfns.c, print.c:
8039 Include float.h unconditionally.
8040 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
8041 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
8042 * regex.c: Likewise for stddef.h, string.h.
8043 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
8044 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
8045 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
8046 (STDC_HEADERS): Remove obsolete defines.
8047 * sysdep.c: Include limits.h unconditionally.
8049 Assume support for memcmp, memcpy, memmove, memset.
8050 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
8051 * regex.c (memcmp, memcpy):
8052 Remove; we assume C89 now.
8054 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
8055 (__malloc_safe_bcopy): Remove; no longer needed.
8057 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
8058 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
8059 well either way, and we prefer signed to unsigned.
8061 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
8063 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
8064 closes the connection while we're reading (bug#9182).
8066 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
8068 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
8069 are specified (Bug#9168).
8071 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
8073 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
8074 Found by GCC static checking and --with-wide-int on a 32-bit host.
8076 2011-07-25 Eli Zaretskii <eliz@gnu.org>
8078 * xdisp.c (compute_display_string_pos): Fix logic of caching
8079 previous display string position. Initialize cached_prev_pos to
8080 -1. Fixes slow-down at the beginning of a buffer.
8082 2011-07-24 Eli Zaretskii <eliz@gnu.org>
8084 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
8085 for attrs[LFACE_FONTSET_INDEX].
8087 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
8089 * xml.c (parse_region): Remove unused local
8090 that was recently introduced.
8092 2011-07-23 Eli Zaretskii <eliz@gnu.org>
8094 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
8095 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
8097 * xdisp.c (move_it_in_display_line_to): Record the best matching
8098 position for TO_CHARPOS while scanning the line, and restore it on
8099 exit if none of the characters scanned was an exact match.
8100 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
8101 when exact match is impossible due to invisible text, and the
8102 lines are truncated.
8104 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
8106 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
8109 2011-07-22 Eli Zaretskii <eliz@gnu.org>
8111 Fix a significant slow-down of cursor motion with C-n, C-p,
8112 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
8113 auto-repeat under bidi redisplay in fontified buffers.
8114 * xdisp.c (compute_stop_pos_backwards): New function.
8115 (next_element_from_buffer): Call compute_stop_pos_backwards to
8116 find a suitable prev_stop when we find ourselves before
8118 (reseat): Don't look for prev_stop, as that could mean a very long
8120 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
8121 <cached_disp_overlay_modiff>: Cache for last found display string
8123 (compute_display_string_pos): Return the cached position if asked
8124 about the same buffer in the same area of character positions, and
8125 the buffer wasn't changed since the time the display string
8126 position was cached.
8128 2011-07-22 Eli Zaretskii <eliz@gnu.org>
8130 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
8131 is an integer, which is important for empty lines. (Bug#9149)
8133 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
8135 * frame.c (Fmodify_frame_parameters): In tty case, update the
8136 default face if necessary (Bug#4238).
8138 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
8140 * editfns.c (Fstring_to_char): No need to explain what a character
8141 is in the docstring (Bug#6576).
8143 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
8145 * xml.c (parse_region): Make sure we always return a tree.
8147 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
8149 * xml.c (parse_region): If a document contains only comments,
8152 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
8154 * xml.c (make_dom): Return comments, too.
8156 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
8159 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
8160 and the surrounding thread.
8161 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
8162 rather than fgets, and retry after EINTR. Otherwise, 'emacs
8163 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
8165 * s/openbsd.h (BROKEN_SIGIO): Define.
8166 * unexelf.c (unexec) [__OpenBSD__]:
8167 Don't update the .mdebug section of the Alpha COFF symbol table.
8169 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
8171 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
8174 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
8176 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
8177 This fixes some race conditions on the permissions of any newly
8180 * alloc.c (valid_pointer_p): Use pipe, not open.
8181 This fixes some permissions issues when debugging.
8183 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
8184 If fchown fails to set both uid and gid, try to set just gid,
8185 as that is sometimes allowed. Adjust the file's mode to eliminate
8186 setuid or setgid bits that are inappropriate if fchown fails.
8188 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
8190 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
8191 to compare Lisp_Objects.
8192 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
8193 global_gnutls_log_level, don't mistake it for a Lisp_Object.
8194 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
8196 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
8198 * lread.c (read_integer): Unread even EOF character.
8199 (read1): Likewise. Properly record start position of symbol.
8201 * lread.c (read1): Read `#:' as empty uninterned symbol if no
8202 symbol character follows.
8204 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
8206 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
8207 This works around a problem with the previous change to Fcopy_file.
8208 Recent glibc declares fchown with __attribute__((warn_unused_result)),
8209 and without this change, GCC might complain about discarding
8210 fchown's return value.
8212 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
8214 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
8216 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
8218 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
8220 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
8222 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
8223 it's used from the C level.
8225 * process.c: Use the same condition for POLL_FOR_INPUT in both
8226 keyboard.c and process.c (bug#1858).
8228 2011-07-09 Lawrence Mitchell <wence@gmx.li>
8230 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
8231 (Fgnutls_boot): Use it.
8233 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
8235 * doc.c (Fsubstitute_command_keys): Revert last change.
8237 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
8239 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
8240 quotes the next character, and doesn't affect other longer
8241 sequences (bug#8935).
8243 * lread.c (syms_of_lread): Clarify that is isn't only
8244 `eval-buffer' and `eval-defun' that's affected by
8245 `lexical-binding' (bug#8460).
8247 2011-07-15 Eli Zaretskii <eliz@gnu.org>

8308 the iterator is before prev_stop.
8309 (init_iterator): Initialize bidi_p from the default value of

8786 (clone_per_buffer_values): Don't assume that

8827 Random fixes. E.g., (random) never returned negative values.
8828 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
8829 subseconds part to the entropy, as that's a bit more random.
8830 Prefer signed to unsigned, since the signedness doesn't matter and
8831 in general we prefer signed. When given a limit, use a
8832 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
8833 latter isn't right if USE_2_TAGS_FOR_INTS.
8834 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
8835 not 0..VALMASK. Don't discard "excess" bits that random () returns.

8848 This is more efficient than Ffile_directory_p and avoids a minor race.
8850 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
8852 * buffer.c (Foverlay_put): Say what the return value is
8855 * fileio.c (barf_or_query_if_file_exists): Check first if the file
8856 is a directory before asking whether to use the file name
8858 (barf_or_query_if_file_exists): Make the "File is a directory"
8859 error be more correct.
8861 * fns.c (Frequire): Remove the mention of the .gz files, since
8862 that's installation-specific, but keep the mention of
8863 `get-load-suffixes'.
8865 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
8867 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

8878 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.

8980 * eval.c (struct backtrace): Simplify and port the data structure.
8981 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
8982 signed bit field, as this assumption is not portable and it makes
8983 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
8984 "char debug_on_exit : 1" as this is not portable either; instead,
8985 use the portable "unsigned int debug_on_exit : 1". Remove unused
8986 member evalargs. Remove obsolete comments about cc bombing out.
8988 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

9165 Use ptrdiff_t, not int, for sizes.
9166 Don't increment bufsize until after realloc succeeds.
9167 Check for size-calculation overflow.
9168 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
9170 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
9172 * lread.c: Integer overflow fixes.
9173 (read_integer): Radix is now EMACS_INT, not int,
9174 to improve quality of diagnostics for out-of-range radices.
9175 Calculate buffer size correctly for out-of-range radices.
9176 (read1): Check for integer overflow in radices, and in
9177 read-circle numbers.
9178 (read_escape): Avoid int overflow.
9179 (Fload, openp, read_buffer_size, read1)
9180 (substitute_object_recurse, read_vector, read_list, map_obarray):
9181 Use ptrdiff_t, not int, for sizes.
9182 (read1): Use EMACS_INT, not int, for sizes.
9183 Check for size overflow.
9185 * image.c (cache_image): Check for size arithmetic overflow.
9187 * lread.c: Integer overflow issues.
9188 (saved_doc_string_size, saved_doc_string_length)
9189 (prev_saved_doc_string_size, prev_saved_doc_string_length):
9190 Now ptrdiff_t, not int.
9191 (read1): Don't assume doc string length fits in int. Check for
9192 out-of-range doc string lengths.
9193 (read_list): Don't assume file position fits in int.
9194 (read_escape): Check for hex character overflow.
9196 2011-06-22 Leo Liu <sdl.web@gmail.com>
9198 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
9199 Move to minibuffer.el.
9201 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
9203 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
9204 The following patches are for when GLYPH_DEBUG && !XASSERT.
9205 * dispextern.h (trace_redisplay_p, dump_glyph_string):
9206 * dispnew.c (flush_stdout):
9207 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
9208 Mark as externally visible.
9209 * dispnew.c (check_window_matrix_pointers): Now static.
9210 * dispnew.c (window_to_frame_vpos):
9211 * xfns.c (unwind_create_frame):
9212 * xterm.c (x_check_font): Remove unused local.
9213 * scroll.c (CHECK_BOUNDS):
9214 * xfaces.c (cache_fache): Rename local to avoid shadowing.
9215 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
9216 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
9217 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
9218 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
9220 (debug_method_add): Use va_list and vsprintf rather than relying
9221 on undefined behavior with wrong number of arguments.
9222 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
9223 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
9224 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
9225 since we're not interested in debugging glyphs with old libraries.
9226 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
9227 GCC 4.6.0's static checking.
9229 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
9231 Integer overflow and signedness fixes (Bug#8873).
9232 A few related buffer overrun fixes, too.

9236 * dispextern.h (struct face.stipple):
9237 * image.c (x_bitmap_height, x_bitmap_width, x_bitmap_pixmap)
9238 (x_bitmap_mask, x_allocate_bitmap_record)
9239 (x_create_bitmap_from_data, x_create_bitmap_from_file)
9240 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
9241 (x_create_bitmap_from_xpm_data):
9242 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
9243 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
9245 * xfaces.c (load_pixmap):
9246 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
9247 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
9248 (.bitmaps_last, struct x_output.icon_bitmap):
9249 Use ptrdiff_t, not int, for bitmap indexes.
9250 (x_allocate_bitmap_record): Check for size overflow.
9251 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
9253 Use ptrdiff_t, not int, for overlay counts.
9254 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
9255 * editfns.c (overlays_around, get_pos_property):
9256 * textprop.c (get_char_property_and_overlay):
9257 * xdisp.c (next_overlay_change, note_mouse_highlight):
9258 * xfaces.c (face_at_buffer_position):
9259 * buffer.c (OVERLAY_COUNT_MAX): New macro.
9260 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
9261 (Fnext_overlay_change, Fprevious_overlay_change)
9262 (mouse_face_overlay_overlaps, Foverlays_in):
9263 Use ptrdiff_t, not int, for sizes.
9264 (overlays_at, overlays_in): Check for size-calculation overflow.
9266 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
9268 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
9269 (x_session_initialize): Do not assume string length fits in int.
9271 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
9272 This is unlikely, but can occur if DPI is outlandish.
9274 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
9275 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
9277 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
9278 * xrdb.c (magic_file_p, search_magic_path):
9279 Omit last arg SUFFIX; it was always 0. All callers changed.
9280 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
9282 * xfont.c (xfont_match): Avoid need for strlen.
9284 * xfns.c: Don't assume strlen fits in int.
9285 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
9287 * xdisp.c (message_log_check_duplicate): Return intmax_t,
9288 not unsigned long, as we prefer signed integers. All callers changed.
9289 Detect integer overflow in repeat count.
9290 (message_dolog): Don't assume print length fits in 39 bytes.
9291 (display_mode_element): Don't assume strlen fits in int.
9293 * termcap.c: Don't assume sizes fit in int and never overflow.
9294 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
9295 (gobble_line): Check for size-calculation overflow.
9297 * minibuf.c (Fread_buffer):
9298 * lread.c (intern, intern_c_string):
9299 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
9300 Don't assume string length fits in int.
9302 * keyboard.c (parse_tool_bar_item):
9303 * gtkutil.c (style_changed_cb): Avoid need for strlen.
9305 * font.c: Don't assume string length fits in int.
9306 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
9307 Use ptrdiff_t, not int.
9308 (font_intern_prop): Don't assume string length fits in int.
9309 Don't assume integer property fits in fixnum.
9310 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
9312 * filelock.c: Fix some buffer overrun and integer overflow issues.
9313 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
9314 Reformulate so as not to need the command string.
9315 Invoke gzip -cd rather than gunzip, as it's more portable.
9316 (lock_info_type, lock_file_1, lock_file):
9317 Don't assume pid_t and time_t fit in unsigned long.
9318 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
9319 (current_lock_owner): Prefer signed type for sizes.
9320 Use memcpy, not strncpy, where memcpy is what is really wanted.
9321 Don't assume (via atoi) that time_t and pid_t fit in int.
9322 Check for time_t and/or pid_t out of range, e.g., via a network share.
9323 Don't alloca where an auto var works fine.
9325 * fileio.c: Fix some integer overflow issues.
9326 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
9327 Don't assume string length fits in int.
9328 (directory_file_name): Don't assume string length fits in long.
9329 (make_temp_name): Don't assume pid fits in int, or that its print
9330 length is less than 20.
9332 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
9334 * coding.c (make_subsidiaries): Don't assume string length fits in int.
9336 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
9338 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
9339 We prefer signed integers, even for size calculations.
9341 * emacs.c: Don't assume string length fits in 'int'.
9342 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
9343 (main): Don't invoke strlen when not needed.
9345 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
9346 (XD_DEBUG_MESSAGE): Don't waste a byte.
9348 * callproc.c (getenv_internal_1, getenv_internal)
9350 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
9352 * lread.c (invalid_syntax): Omit length argument.
9353 All uses changed. This doesn't fix a bug, but it simplifies the
9354 code away from its former Hollerith-constant appearance, and it's
9355 one less 'int' to worry about when looking at integer-overflow issues.
9356 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
9358 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
9359 This didn't break anything, but it didn't help either.
9360 It's confusing to put a bogus integer in a place where the actual
9361 value does not matter.
9362 (LIST_END_P): Remove unused macro and its bogus comment.
9363 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
9365 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
9366 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
9368 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
9369 We prefer signed types, and the value cannot exceed the EMACS_INT
9370 range anyway (because otherwise the length would not be representable).
9371 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
9372 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
9373 This avoids a GCC warning when WIDE_EMACS_INT.
9375 * indent.c (sane_tab_width): New function.
9376 (current_column, scan_for_column, Findent_to, position_indentation)
9377 (compute_motion): Use it. This is just for clarity.
9378 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
9380 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
9382 * lisp.h (lint_assume): New macro.
9383 * composite.c (composition_gstring_put_cache):
9384 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
9386 * editfns.c, insdel.c:
9387 Omit unnecessary forward decls, to simplify future changes.
9389 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
9391 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
9393 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
9394 Use much-faster test for byte-length change.
9395 Don't assume string byte-length fits in 'int'.
9396 Check that character arg fits in 'int'.
9397 (mapcar1): Declare byte as byte, for clarity.
9399 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
9401 * fns.c (concat): Catch string overflow earlier.
9402 Do not rely on integer wraparound.
9404 * dispextern.h (struct it.overlay_strings_charpos)
9405 (struct it.selective): Now EMACS_INT, not int.
9406 * xdisp.c (forward_to_next_line_start)
9407 (back_to_previous_visible_line_start)
9408 (reseat_at_next_visible_line_start, next_element_from_buffer):
9409 Don't arbitrarily truncate the value of 'selective' to int.
9411 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
9413 * composite.c: Don't truncate sizes to 'int'.
9414 (composition_gstring_p, composition_reseat_it)
9415 (composition_adjust_point): Use EMACS_INT, not int.
9416 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
9417 not EMACS_UINT, for indexes.
9419 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
9421 * buffer.c: Include <verify.h>.
9422 (struct sortvec.priority, struct sortstr.priority):
9423 Now EMACS_INT, not int.
9424 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
9425 (struct sortstr.size, record_overlay_string)
9426 (struct sortstrlist.size, struct sortlist.used):
9427 Don't truncate size to int.
9428 (record_overlay_string): Check for size-calculation overflow.
9429 (init_buffer_once): Check at compile-time, not run-time.
9431 2011-06-22 Jim Meyering <meyering@redhat.com>
9433 Don't leak an XBM-image-sized buffer
9434 * image.c (xbm_load): Free the image buffer after using it.
9436 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
9439 * composite.c (find_automatic_composition): Omit needless 'return 0;'
9440 that Sun C diagnosed.
9441 * fns.c (secure_hash): Fix pointer signedness issue.
9442 * intervals.c (static_offset_intervals): New function.
9443 (offset_intervals): Use it.
9445 2011-06-21 Leo Liu <sdl.web@gmail.com>
9448 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
9451 * fns.c (secure_hash): Rename from crypto_hash_function and change
9452 the first arg to accept symbols.
9453 (Fsecure_hash): New primitive.
9454 (syms_of_fns): New symbols.
9456 2011-06-20 Deniz Dogan <deniz@dogan.se>
9458 * process.c (Fset_process_buffer): Clarify return value in
9461 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
9463 * dispnew.c (add_window_display_history): Use BVAR.
9465 * xdisp.c (debug_method_add): Use BVAR.
9466 (check_window_end, dump_glyph_matrix, dump_glyph)
9467 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
9469 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
9472 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
9473 check till after the cache is created in init_frame_faces.
9475 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
9477 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
9479 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
9481 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
9482 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
9483 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
9485 Improve buffer-overflow checking (Bug#8873).
9486 * fileio.c (Finsert_file_contents):
9487 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
9488 Remove the old (too-loose) buffer overflow checks.
9489 They weren't needed, since make_gap checks for buffer overflow.
9490 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
9491 The old code merely checked for Emacs fixnum overflow, and relied
9492 on undefined (wraparound) behavior. The new code avoids undefined
9493 behavior, and also checks for ptrdiff_t and/or size_t overflow.
9495 * editfns.c (Finsert_char): Don't dump core with very negative counts.
9496 Tune. Don't use wider integers than needed. Don't use alloca.
9497 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
9499 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
9501 * insdel.c, lisp.h (buffer_overflow): New function.
9502 (insert_from_buffer_1, replace_range, replace_range_2):
9503 * insdel.c (make_gap_larger):
9504 * editfns.c (Finsert_char):
9505 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
9507 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
9509 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
9511 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
9513 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
9514 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
9516 * fileio.c: Don't assume EMACS_INT fits in off_t.
9517 (emacs_lseek): New static function.
9518 (Finsert_file_contents, Fwrite_region): Use it.
9519 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
9521 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
9523 * fns.c: Don't overflow int when computing a list length.
9524 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
9525 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
9526 truncation on 64-bit hosts. Check for QUIT every
9527 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
9528 faster and is responsive enough.
9529 (Flength): Report an error instead of overflowing an integer.
9530 (Fsafe_length): Return a float if the value is not representable
9531 as a fixnum. This shouldn't happen except in contrived situations.
9532 (Fnthcdr, Fsort): Don't assume list length fits in int.
9533 (Fcopy_sequence): Don't assume vector length fits in int.
9535 * alloc.c: Check that resized vectors' lengths fit in fixnums.
9536 (header_size, word_size): New constants.
9537 (allocate_vectorlike): Don't check size overflow here.
9538 (allocate_vector): Check it here instead, since this is the only
9539 caller of allocate_vectorlike that could cause overflow.
9540 Check that the new vector's length is representable as a fixnum.
9542 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
9543 The previous code was bogus. For example, next_almost_prime (32)
9544 returned 39, which is undesirable as it is a multiple of 3; and
9545 next_almost_prime (24) returned 25, which is a multiple of 5 so
9546 why was the code bothering to check for multiples of 7?
9548 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
9550 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
9552 Variadic C functions now count arguments with ptrdiff_t.
9553 This partly undoes my 2011-03-30 change, which replaced int with size_t.
9554 Back then I didn't know that the Emacs coding style prefers signed int.
9555 Also, in the meantime I found a few more instances where arguments
9556 were being counted with int, which may truncate counts on 64-bit
9557 machines, or EMACS_INT, which may be unnecessarily wide.
9558 * lisp.h (struct Lisp_Subr.function.aMANY)
9559 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
9560 Arg counts are now ptrdiff_t, not size_t.
9561 All variadic functions and their callers changed accordingly.
9562 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
9563 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
9564 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
9565 * callint.c (Fcall_interactively): Check arg count for overflow,
9566 to avoid potential buffer overrun. Use signed char, not 'int',
9567 for 'varies' array, so that we needn't bother to check its size
9568 calculation for overflow.
9569 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
9570 * eval.c (apply_lambda):
9571 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
9572 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
9573 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
9575 * callint.c (Fcall_interactively): Don't use index var as event count.
9577 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
9578 * mem-limits.h (SIZE): Remove; no longer used.
9580 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
9582 Remove unnecessary casts.
9583 * xterm.c (x_term_init):
9584 * xfns.c (x_set_border_pixel):
9585 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
9586 These aren't needed now that we assume ANSI C.
9588 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
9589 It's more likely to cause problems (due to unsigned overflow)
9592 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
9594 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
9596 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
9598 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
9600 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
9602 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
9604 GLYPH_CODE_FACE returns EMACS_INT, not int.
9605 * dispextern.h (merge_faces):
9606 * xfaces.c (merge_faces):
9607 * xdisp.c (get_next_display_element, next_element_from_display_vector):
9608 Don't assume EMACS_INT fits in int.
9610 * character.h (CHAR_VALID_P): Remove unused parameter.
9611 * fontset.c, lisp.h, xdisp.c: All uses changed.
9613 * editfns.c (Ftranslate_region_internal): Omit redundant test.
9615 * fns.c (concat): Minor tuning based on overflow analysis.
9616 This doesn't fix any bugs. Use int to hold character, instead
9617 of constantly refetching from Emacs object. Use XFASTINT, not
9618 XINT, for value known to be a character. Don't bother comparing
9619 a single byte to 0400, as it's always less.
9621 * floatfns.c (Fexpt):
9622 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
9624 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
9627 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
9629 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
9630 Without this fix, on a 64-bit host (aset S 0 4294967386) would
9631 incorrectly succeed when S was a string, because 4294967386 was
9632 truncated before it was used.
9634 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
9635 Otherwise, an out-of-range integer could cause undefined behavior
9638 * composite.c: Use int, not EMACS_INT, for characters.
9639 (fill_gstring_body, composition_compute_stop_pos): Use int, not
9640 EMACS_INT, for values that are known to be in character range.
9641 This doesn't fix any bugs but is the usual style inside Emacs and
9642 may generate better code on 32-bit machines.
9644 Make sure a 64-bit char is never passed to ENCODE_CHAR.
9645 This is for reasons similar to the recent CHAR_STRING fix.
9646 * charset.c (Fencode_char): Check that character arg is actually
9647 a character. Pass an int to ENCODE_CHAR.
9648 * charset.h (ENCODE_CHAR): Verify that the character argument is no
9649 wider than 'int', as a compile-time check to prevent future regressions
9652 * character.c (char_string): Remove unnecessary casts.
9654 Make sure a 64-bit char is never passed to CHAR_STRING.
9655 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
9656 by silently ignoring the top 32 bits, allowing some values
9657 that were far too large to be valid characters.
9658 * character.h: Include <verify.h>.
9659 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
9660 arguments are no wider than unsigned, as a compile-time check
9661 to prevent future regressions in this area.
9663 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
9664 (Fsubst_char_in_region):
9666 * xdisp.c (decode_mode_spec_coding):
9667 Adjust to CHAR_STRING's new requirement.
9668 * editfns.c (Finsert_char, Fsubst_char_in_region):
9669 * fns.c (concat): Check that character args are actually
9670 characters. Without this test, these functions did the wrong
9671 thing with wildly out-of-range values on 64-bit hosts.
9673 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
9674 These casts should not be needed on 32-bit hosts, either.
9675 * keyboard.c (read_char):
9676 * lread.c (Fload): Remove casts to unsigned.
9678 * lisp.h (UNSIGNED_CMP): New macro.
9679 This fixes comparison bugs on 64-bit hosts.
9680 (ASCII_CHAR_P): Use it.
9681 * casefiddle.c (casify_object):
9682 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
9683 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
9684 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
9685 * dispextern.h (FACE_FROM_ID):
9686 * keyboard.c (read_char): Use UNSIGNED_CMP.
9688 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
9689 not to EMACS_INT, to avoid GCC warning.
9691 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
9693 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
9694 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
9695 isn't needed on 32-bit machines.
9697 * buffer.c (Fgenerate_new_buffer_name):
9698 Use EMACS_INT for count, not int.
9699 (advance_to_char_boundary): Return EMACS_INT, not int.
9701 * data.c (Qcompiled_function): Now static.
9703 * window.c (window_body_lines): Now static.
9705 * image.c (gif_load): Rename local to avoid shadowing.
9707 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
9708 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
9709 * alloc.c (make_save_value): Integer argument is now of type
9711 (mark_object): Use ptrdiff_t, not int.
9712 * lisp.h (pD): New macro.
9713 * print.c (print_object): Use it.
9715 * alloc.c: Use EMACS_INT, not int, to count objects.
9716 (total_conses, total_markers, total_symbols, total_vector_size)
9717 (total_free_conses, total_free_markers, total_free_symbols)
9718 (total_free_floats, total_floats, total_free_intervals)
9719 (total_intervals, total_strings, total_free_strings):
9720 Now EMACS_INT, not int. All uses changed.
9721 (Fgarbage_collect): Compute overall total using a double, so that
9722 integer overflow is less likely to be a problem. Check for overflow
9723 when converting back to an integer.
9724 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
9725 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
9726 These were 'int' variables that could overflow on 64-bit hosts;
9727 they were never used, so remove them instead of repairing them.
9728 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
9729 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
9730 Previously, this ceilinged at INT_MAX, but that doesn't work on
9732 (allocate_pseudovector): Don't use EMACS_INT when int would do.
9734 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
9735 (allocate_vectorlike): Check for ptrdiff_t overflow.
9736 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
9737 when a (possibly-narrower) signed value would do just as well.
9738 We prefer using signed arithmetic, to avoid comparison confusion.
9740 * alloc.c: Catch some string size overflows that we were missing.
9741 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
9742 for convenience in STRING_BYTES_MAX.
9743 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
9744 The definition here is exact; the one in lisp.h was approximate.
9745 (allocate_string_data): Check for string overflow. This catches
9746 some instances we weren't catching before. Also, it catches
9747 size_t overflow on (unusual) hosts where SIZE_MAX <= min
9748 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
9749 and ptrdiff_t and EMACS_INT are both 64 bits.
9751 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
9752 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
9753 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
9755 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
9757 * alloc.c (Fmake_string): Check for out-of-range init.
9759 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
9761 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.

9774 Call gtk_window_set_resizable if HAVE_GTK3.
9775 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
9776 and height if HAVE_GTK3 (Bug#8505).
9777 (scroll_bar_width_for_theme): New variable.
9778 (update_theme_scrollbar_width): New function.
9779 (xg_get_default_scrollbar_width): Move code to
9780 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
9781 (xg_initialize): Call update_theme_scrollbar_width.
9783 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
9785 * emacsgtkfixed.c, emacsgtkfixed.h: New files.

10342 were just reseat()'ed to a new position.
10344 * xdisp.c (set_cursor_from_row): Set start and stop points
10345 according to the row's direction when priming the loop that looks
10346 for the glyph on which to display cursor.

10348 (display_prop_intangible_p): Reimplement to call
10349 handle_display_spec instead of single_display_spec_intangible_p.

10360 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
10361 value of a `display' property is a "replacing spec".
10362 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
10363 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
10364 the display property, but just return a value indicating whether
10365 the display property will replace the characters it covers.
10366 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
10367 frame_window_p members of struct bidi_it.

10393 * gnutls.c: Use Emacs's memory allocators.
10394 Without this change, the gnutls library would invoke malloc etc.
10395 directly, which causes problems on non-SYNC_INPUT hosts, and which
10396 runs afoul of improving memory_full behavior. (Bug#8761)
10397 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
10398 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
10399 xfree instead of the default malloc, realloc, free.
10400 (Fgnutls_boot): No need to check for memory allocation failure,
10401 since xmalloc does that for us.

10430 need to be updated by these changes.
10431 * fns.c (make_hash_table, maybe_resize_hash_table):
10432 Check for integer overflow with large hash tables.
10433 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
10434 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
10435 (SXHASH_REDUCE): New macro.
10436 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
10437 Use it instead of discarding useful hash info with large hash values.
10438 (sxhash_float): New function.
10439 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
10440 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
10441 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
10442 Rewrite to use FIXNUM_BITS, as this simplifies things.
10443 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
10444 Adjust signatures to match updated version of code.
10445 (consing_since_gc): Now EMACS_INT, since a single hash table can
10446 use more than INT_MAX bytes.

10495 Make it possible to run ./temacs.
10497 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
10498 syms_of_callproc does the same thing. Remove test for
10499 "initialized", do it in the caller.
10500 * emacs.c (main): Avoid calling set_initial_environment when dumping.
10502 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
10504 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
10505 (read_minibuf): Use get_minibuffer.
10506 (syms_of_minibuf): Use DEFSYM.
10507 (Qmetadata): New var.
10508 * data.c (Qbuffer): Don't make it static.
10509 (syms_of_data): Use DEFSYM.
10511 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
10513 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
10514 (CCL_CODE_MIN): New macro.
10516 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
10518 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
10520 * eval.c (Qdebug): Now static.
10521 * lisp.h (Qdebug): Remove decl. This reverts a part of the
10522 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
10523 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
10525 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
10527 * image.c: Various fixes to ImageMagick code comments.
10528 (Fimagemagick_types): Doc fix.
10530 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
10532 Minor fixes prompted by GCC 4.6.0 warnings.
10534 * xselect.c (converted_selections, conversion_fail_tag): Now static.
10536 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
10537 (x_clipboard_manager_save_all): Move extern decl to ...
10538 * xterm.h: ... here, so that it can be checked for consistency.
10540 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
10542 * xselect.c (x_clipboard_manager_save_frame)
10543 (x_clipboard_manager_save_all): New functions.
10544 (Fx_clipboard_manager_save): Lisp function deleted.
10546 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
10547 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
10549 * xterm.h: Update prototype.
10551 2011-05-28 William Xu <william.xwl@gmail.com>
10553 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
10554 exiting (Bug#8239).
10556 2011-05-28 Jim Meyering <meyering@redhat.com>
10558 Avoid a sign-extension bug in crypto_hash_function.
10559 * fns.c (to_uchar): Define.
10560 (crypto_hash_function): Use it to convert some newly-signed
10561 variables to unsigned, to avoid sign-extension bugs. For example,
10562 without this change, (md5 "truc") would evaluate to
10563 45723a2aff78ff4fff7fff1114760e62 rather than the expected
10564 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
10565 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
10567 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
10569 Integer overflow fixes.
10571 * dbusbind.c: Serial number integer overflow fixes.
10572 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
10573 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
10574 to hold a serial number that is too large for a fixnum.
10575 (Fdbus_method_return_internal, Fdbus_method_error_internal):
10576 Check for serial numbers out of range. Decode any serial number
10577 that was so large that it became a float. (Bug#8722)
10579 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
10580 (Fdbus_call_method, Fdbus_call_method_asynchronously):
10581 Use XFASTINT rather than XUINT when numbers are nonnegative.
10582 (xd_append_arg, Fdbus_method_return_internal):
10583 (Fdbus_method_error_internal): Likewise. Also, for unsigned
10584 arguments, check that Lisp number is nonnegative, rather than
10585 silently wrapping negative numbers around. (Bug#8722)
10586 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
10589 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
10591 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
10593 ccl: Add integer overflow checks.
10594 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
10595 (IN_INT_RANGE): New macros.
10596 (ccl_driver): Use them to check for integer overflow when
10597 decoding a CCL program. Many of the new checks are whether XINT (x)
10598 fits in int; it doesn't always, on 64-bit hosts. The new version
10599 doesn't catch all possible integer overflows, but it's an
10600 improvement. (Bug#8719)
10602 * alloc.c (make_event_array): Use XINT, not XUINT.
10603 There's no need for unsigned here.
10605 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
10606 This follows up to the 2011-05-06 change that substituted uintptr_t
10607 for EMACS_INT. This case wasn't caught back then.
10609 Rework Fformat to avoid integer overflow issues.
10610 * editfns.c: Include <float.h> unconditionally, as it's everywhere
10611 now (part of C89). Include <verify.h>.
10612 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
10613 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
10614 (Fformat): Avoid the prepass trying to compute sizes; it was only
10615 approximate and thus did not catch overflow reliably. Instead, walk
10616 through the format just once, formatting and computing sizes as we go,
10617 checking for integer overflow at every step, and allocating a larger
10618 buffer as needed. Keep track separately whether the format is
10619 multibyte. Keep only the most-recently calculated precision, rather
10620 than them all. Record whether each argument has been converted to
10621 string. Use EMACS_INT, not int, for byte and char and arg counts.
10622 Support field widths and precisions larger than INT_MAX. Avoid
10623 sprintf's undefined behavior with conversion specifications such as %#d
10624 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
10625 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
10626 formatting out-of-range floating point numbers with int
10627 formats. (Bug#8668)
10629 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
10631 * data.c: Avoid integer truncation in expressions involving floats.
10632 * data.c: Include <intprops.h>.
10633 (arith_driver): When there's an integer overflow in an expression
10634 involving floating point, convert the integers to floating point
10635 so that the resulting value does not suffer from catastrophic
10636 integer truncation. For example, on a 64-bit host (* 4
10637 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
10638 Do not rely on undefined behavior after integer overflow.
10640 merge count_size_as_multibyte, parse_str_to_multibyte
10641 * character.c, character.h (count_size_as_multibyte):
10642 Rename from parse_str_to_multibyte; all uses changed.
10643 Check for integer overflow.
10644 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
10645 since it's now a duplicate of the other. This is more of
10646 a character than a buffer op, so better that it's in character.c.
10647 * fns.c, print.c: Adjust to above changes.
10649 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
10651 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
10653 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
10655 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
10656 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
10657 (x_clipboard_manager_save): Now static.
10658 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
10660 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
10661 (crypto_hash_function): Now static.
10662 Fix pointer signedness problems. Avoid unnecessary initializations.
10664 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
10666 * termhooks.h (Vselection_alist): Make it terminal-local.
10668 * terminal.c (create_terminal): Initialize it.
10670 * xselect.c: Support for clipboard managers.
10671 (Vselection_alist): Move to termhooks.h as terminal-local var.
10672 (LOCAL_SELECTION): New macro.
10673 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
10674 (symbol_to_x_atom): Remove gratuitous arg.
10675 (x_handle_selection_request, lisp_data_to_selection_data)
10676 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
10677 (x_own_selection, x_get_local_selection, x_convert_selection):
10678 New arg, specifying work frame. Use terminal-local Vselection_alist.
10679 (some_frame_on_display): Delete unused function.
10680 (Fx_own_selection_internal, Fx_get_selection_internal)
10681 (Fx_disown_selection_internal, Fx_selection_owner_p)
10682 (Fx_selection_exists_p): New optional frame arg.
10683 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
10684 (x_handle_selection_clear): Don't treat other terminals with the
10685 same keyboard specially. Use the terminal-local Vselection_alist.
10686 (x_clear_frame_selections): Use Frun_hook_with_args.
10688 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
10690 * xterm.h: Add support for those atoms.
10692 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
10694 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
10695 (converted_selections, conversion_fail_tag): New global variables.
10696 (x_selection_request_lisp_error): Free the above.
10697 (x_get_local_selection): Remove unnecessary code.
10698 (x_reply_selection_request): Args changed; handle arbitrary array
10699 of converted selections stored in converted_selections.
10700 Separate the XChangeProperty and SelectionNotify steps.
10701 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
10702 (x_convert_selection): New function.
10703 (x_handle_selection_event): Simplify.
10704 (x_get_foreign_selection): Don't ignore incoming requests while
10705 waiting for an answer; this will fail when we implement
10706 SAVE_TARGETS, and seems unnecessary anyway.
10707 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
10708 (Vx_sent_selection_functions): Doc fix.
10710 2011-05-26 Leo Liu <sdl.web@gmail.com>
10712 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
10714 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10716 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
10718 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
10719 for fringe update if it has periodic bitmap.
10720 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
10721 and fringe_bitmap_periodic_p.
10723 * fringe.c (get_fringe_bitmap_data): New function.
10724 (draw_fringe_bitmap_1, update_window_fringes): Use it.
10725 (update_window_fringes): Record periodicity of fringe bitmap in glyph
10726 row. Mark glyph row for fringe update if periodicity changed.
10728 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
10729 for fringe update unless it has periodic bitmap.
10731 2011-05-25 Kenichi Handa <handa@m17n.org>
10733 * xdisp.c (get_next_display_element): Set correct it->face_id for
10734 a static composition.
10736 2011-05-24 Leo Liu <sdl.web@gmail.com>
10739 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
10741 * fns.c (crypto_hash_function, Fsha1): New function.
10742 (Fmd5): Use crypto_hash_function.
10743 (syms_of_fns): Add Ssha1.
10745 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
10747 * gnutls.c: Remove unused macros.
10748 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
10749 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
10750 Remove macros that are defined and never used.
10751 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
10753 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
10755 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
10756 (Fx_get_selection_internal): Minor cleanup.
10757 (Fx_own_selection_internal): Rename arguments for consistency with
10760 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
10762 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
10764 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
10766 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
10768 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10770 * dispnew.c (scrolling_window): Don't exclude the case that the
10771 last enabled row in the desired matrix touches the bottom boundary.
10773 2011-05-21 Glenn Morris <rgm@gnu.org>
10775 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
10776 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
10777 and add some more files.
10779 2011-05-20 Eli Zaretskii <eliz@gnu.org>
10781 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
10782 report_file_error introduced by the change from 2011-05-07.
10784 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
10786 * systime.h (Time): Define only if emacs is defined.
10787 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
10788 where the include path doesn't have X11/X.h by default. See
10789 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
10791 2011-05-20 Kenichi Handa <handa@m17n.org>
10793 * composite.c (find_automatic_composition): Fix previous change.
10795 2011-05-20 Glenn Morris <rgm@gnu.org>
10797 * lisp.mk: New file, split from Makefile.in.
10798 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
10799 (shortlisp): Remove.
10800 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
10802 2011-05-19 Glenn Morris <rgm@gnu.org>
10804 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
10805 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
10806 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
10807 (lisp): Set the order to that of loadup.el.
10808 (shortlisp): Make it a copy of $lisp.
10809 (SOME_MACHINE_LISP): Remove.
10810 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
10811 Use just $shortlisp, not $SOME_MACHINE_LISP too.
10813 2011-05-18 Kenichi Handa <handa@m17n.org>
10815 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
10816 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
10817 (find_automatic_composition): Mostly rewrite for efficiency.
10819 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
10821 * makefile.w32-in: Update dependencies.
10823 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
10825 * menu.c: Include limits.h (fixes the MS-Windows build broken by
10826 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
10828 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
10830 Fix some integer overflow issues, such as string length overflow.
10832 * insdel.c (count_size_as_multibyte): Check for string overflow.
10834 * character.c (lisp_string_width): Check for string overflow.
10835 Use EMACS_INT, not int, for string indexes and lengths; in
10836 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
10837 the resulting string length overflows an EMACS_INT; instead,
10838 report a string overflow if no precision given. When checking for
10839 precision exhaustion, use a check that cannot possibly have
10840 integer overflow. (Bug#8675)
10841 * character.h (lisp_string_width): Adjust to new signature.
10843 * alloc.c (string_overflow): New function.
10844 (Fmake_string): Use it. This doesn't change behavior, but saves
10845 a few bytes and will simplify future changes.
10846 * character.c (string_escape_byte8): Likewise.
10847 * lisp.h (string_overflow): New decl.
10849 Fixups, following up to the user-interface timestamp change.
10850 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
10851 for UI timestamps, instead of unsigned long.
10852 * msdos.c (mouse_get_pos): Likewise.
10853 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
10854 * w32gui.h (Time): Define by including "systime.h" rather than by
10855 declaring it ourselves. (Bug#8664)
10857 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
10858 * image.c (clear_image_cache): Likewise.
10860 * term.c (term_mouse_position): Don't assume time_t wraparound.
10862 Be more systematic about user-interface timestamps.
10863 Before, the code sometimes used 'Time', sometimes 'unsigned long',
10864 and sometimes 'EMACS_UINT', to represent these timestamps.
10865 This change causes it to use 'Time' uniformly, as that's what X uses.
10866 This makes the code easier to follow, and makes it easier to catch
10867 integer overflow bugs such as Bug#8664.
10868 * frame.c (Fmouse_position, Fmouse_pixel_position):
10869 Use Time, not unsigned long, for user-interface timestamps.
10870 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
10871 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
10872 * keyboard.h (last_event_timestamp): Likewise.
10873 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
10874 * menu.h (xmenu_show): Likewise.
10875 * term.c (term_mouse_position): Likewise.
10876 * termhooks.h (struct input_event.timestamp): Likewise.
10877 (struct terminal.mouse_position_hook): Likewise.
10878 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
10879 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
10880 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
10881 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
10882 what it was before.
10883 * menu.h, termhooks.h: Include "systime.h", for Time.
10885 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
10886 Don't assume that the difference between two unsigned long values
10887 can fit into an integer. At this point, we know button_down_time
10888 <= event->timestamp, so the difference must be nonnegative, so
10889 there's no need to cast the result if double-click-time is
10890 nonnegative, as it should be; check that it's nonnegative, just in
10891 case. This bug is triggered when events are more than 2**31 ms
10892 apart (about 25 days). (Bug#8664)
10894 * xselect.c (last_event_timestamp): Remove duplicate decl.
10895 (x_own_selection): Remove needless cast to unsigned long.
10897 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
10898 that always fit in int. Use a sentinel instead of a counter, to
10899 avoid a temp and to allay GCC's concerns about possible int overflow.
10900 * frame.h (struct frame): Use int for menu_bar_items_used
10901 instead of EMACS_INT, since it always fits in int.
10903 * menu.c (grow_menu_items): Check for int overflow.
10905 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
10907 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
10908 Before, the code was not consistent. These values cannot exceed
10909 2**31 - 1 so there's no need to make them unsigned.
10910 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
10911 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
10912 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
10914 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
10916 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
10917 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
10918 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
10919 presumably because the widths might not match.
10921 * window.c (size_window): Avoid needless test at loop start.
10923 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
10925 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
10927 2011-05-12 Drew Adams <drew.adams@oracle.com>
10929 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
10931 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10933 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
10934 `width' to `bar_area_x' and `bar_area_width', respectively.
10935 (x_scroll_run): Take account of fringe background extension.
10937 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
10938 Rename local vars `left' and `width' to `bar_area_x' and
10939 `bar_area_width', respectively.
10940 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
10941 background extension.
10943 2011-05-10 Jim Meyering <meyering@redhat.com>
10945 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
10947 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
10949 * image.c (Finit_image_library): Return t for built-in image types,
10950 like pbm and xbm. (Bug#8640)
10952 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
10954 * w32menu.c (set_frame_menubar): Fix submenu allocation.
10956 2011-05-07 Eli Zaretskii <eliz@gnu.org>
10958 * w32console.c (Fset_screen_color): Doc fix.
10959 (Fget_screen_color): New function.
10960 (syms_of_ntterm): Defsubr it.
10962 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
10963 unlink the temporary file if Fcall_process didn't create it in the
10965 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
10966 child process will be redirected to a file specified with `:file'.
10967 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
10968 cue to call_process_cleanup not to close that handle.
10970 2011-05-07 Ben Key <bkey76@gmail.com>
10972 * makefile.w32-in: The bootstrap-temacs rule now makes use of
10973 one of two shell specific rules, either bootstrap-temacs-CMD or
10974 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
10975 to the previous implementation of the bootstrap-temacs rule.
10976 The bootstrap-temacs-CMD rule is similar to the previous
10977 implementation of the bootstrap-temacs rule except that it
10978 makes use of the ESC_CFLAGS variable instead of the CFLAGS
10981 These changes, along with some changes to nt/configure.bat,
10982 nt/gmake.defs, and nt/nmake.defs, are required to extend my
10983 earlier fix to add support for --cflags and --ldflags options
10984 that include quotes so that it works whether make uses cmd or
10987 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
10989 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
10990 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
10992 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
10993 a string. Handle both cases.
10994 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
10995 (Fdbus_register_method): Use Qinvalid_function.
10997 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
10999 * makefile.w32-in: Update dependencies.
11000 (LISP_H): Add inttypes.h and stdin.h.
11001 (PROCESS_H): Add unistd.h.
11003 2011-05-06 Eli Zaretskii <eliz@gnu.org>
11005 * lread.c: Include limits.h (fixes the MS-Windows build broken by
11006 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
11008 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
11010 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
11012 * term.c (vfatal): Remove stray call to va_end.
11013 It's not needed and the C Standard doesn't allow it here anyway.
11015 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
11016 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
11018 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
11021 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
11023 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
11025 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
11027 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
11029 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
11031 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
11032 * charset.c (Fdefine_charset_internal): Don't initialize
11033 charset.code_space[15]. The value was garbage, on hosts with
11034 32-bit int (Bug#8600).
11036 * lread.c (read_integer): Be more consistent with string-to-number.
11037 Use string_to_number to do the actual conversion; this avoids
11038 rounding errors and fixes some other screwups. Without this fix,
11039 for example, #x1fffffffffffffff was misread as -2305843009213693952.
11040 (digit_to_number): Move earlier, for benefit of read_integer.
11041 Return -1 if the digit is out of range for the base, -2 if it is
11042 not a digit in any supported base. (Bug#8602)
11044 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
11046 * dispnew.c (scrolling_window): Return 1 if we scrolled,
11047 to match comment at start of function. This also removes a
11048 GCC warning about overflow in a 32+64-bit port.
11050 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
11052 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
11053 Reported by Stefan Monnier in
11054 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
11055 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
11056 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
11058 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
11059 (EMACS_UINTPTR): Likewise, with uintptr_t.
11061 * lisp.h: Prefer 64-bit EMACS_INT if available.
11062 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
11063 on 32-bit hosts that have 64-bit int, so that they can access
11065 However, temporarily disable this change unless the temporary
11066 symbol WIDE_EMACS_INT is defined.
11068 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
11070 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
11071 This removes an assumption that EMACS_INT and long are the same
11072 width as pointers. The assumption is true for Emacs porting targets
11073 now, but we want to make other targets possible.
11074 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
11075 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
11076 In the rest of the code, change types of integers that hold casted
11077 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
11078 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
11079 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
11080 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
11081 No need to cast type when ORing.
11082 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
11083 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
11084 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
11085 assume EMACS_INT is the same width as char *.
11086 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
11087 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
11088 Remove no-longer-needed casts.
11089 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
11090 (xg_tool_bar_help_callback, xg_make_tool_item):
11091 Use EMACS_INTPTR to hold an integer
11092 that will be cast to void *; this can avoid a GCC warning
11093 if EMACS_INT is not the same width as void *.
11094 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
11095 * xdisp.c (display_echo_area_1, resize_mini_window_1):
11096 (current_message_1, set_message_1):
11097 Use a local to convert to proper width without a cast.
11098 * xmenu.c (dialog_selection_callback): Likewise.
11100 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
11101 Also, don't assume VALBITS / RAND_BITS is less than 5,
11102 and don't rely on undefined behavior when shifting a 1 left into
11104 * lisp.h (get_random): Change signature to match.
11106 * lread.c (hash_string): Use size_t, not int, for hash computation.
11107 Normally we prefer signed values; but hashing is special, because
11108 it's better to use unsigned division on hash table sizes so that
11109 the remainder is nonnegative. Also, size_t is the natural width
11110 for hashing into memory. The previous code used 'int', which doesn't
11111 retain enough info to hash well into very large tables.
11112 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
11114 * dbusbind.c: Don't possibly lose pointer info when converting.
11115 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
11116 Use XPNTR rather than XHASH, so that the high-order bits of
11117 the pointer aren't lost when converting through void *.
11119 * eval.c (Fautoload): Don't double-shift a pointer.
11121 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
11123 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
11125 * gnutls.c (DEF_GNUTLS_FN):
11126 * image.c (DEF_IMGLIB_FN): Make function pointers static.
11128 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
11130 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
11133 2011-05-05 Eli Zaretskii <eliz@gnu.org>
11135 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
11136 New version that can reserve upto 2GB of heap space.
11138 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
11140 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
11142 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
11144 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
11145 `gnutls_certificate_set_x509_key_file'.
11147 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
11149 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
11150 Update dependencies.
11152 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
11154 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
11155 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
11156 Remove unused parameter `fildes'.
11157 * process.c (read_process_output, send_process): Don't pass it.
11159 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
11161 Fix previous change: the library cache is defined in w32.c.
11162 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
11163 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
11165 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
11167 Implement dynamic loading of GnuTLS on Windows.
11169 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
11170 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
11171 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
11174 * gnutls.c (Qgnutls_dll): Define.
11175 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
11176 (gnutls_*): Declare function pointers.
11177 (init_gnutls_functions): New function to initialize function pointers.

11180 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
11181 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
11182 (emacs_gnutls_write, emacs_gnutls_read)
11183 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
11184 (Fgnutls_available_p): New function.
11185 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
11186 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
11187 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
11189 * image.c: Include w32.h.
11190 (Vimage_type_cache): Delete.

11193 (w32_delayed_load): Move to w32.c.
11195 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
11197 * w32.c (QCloaded_from, Vlibrary_cache): Define.
11198 (w32_delayed_load): Move from image.c. When loading a library, record
11199 its filename in the :loaded-from property of the library id.
11200 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
11201 Initialize and staticpro them.
11202 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
11204 * process.c: Include lisp.h before w32.h, not after.
11205 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
11206 instead of gnutls_record_check_pending.
11208 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
11210 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
11212 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
11213 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
11216 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
11218 * xterm.c (x_set_frame_alpha): Do not set property on anything
11219 else than FRAME_X_OUTER_WINDOW (Bug#8608).

11241 * sysdep.c (wait_for_termination_1): Make static.
11242 (wait_for_termination, interruptible_wait_for_termination):
11243 Move after wait_for_termination_1.
11245 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
11247 * sysdep.c (interruptible_wait_for_termination): New function
11248 which is like wait_for_termination, but allows keyboard
11251 * callproc.c (Fcall_process): Add (:file "file") as an option for
11253 (Fcall_process_region): Ditto.
11255 2011-04-30 Eli Zaretskii <eliz@gnu.org>
11257 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
11258 rather than `XVECTOR (FOO)->size'.
11260 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
11261 inttypes.h, as a gnulib replacement is used if it not available in
11264 2011-04-21 Eli Zaretskii <eliz@gnu.org>
11266 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
11267 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
11268 of MOST_POSITIVE_FIXNUM. (Bug#8528)
11270 * coding.c (coding_alloc_by_realloc): Error out if destination
11271 will grow beyond MOST_POSITIVE_FIXNUM.
11272 (decode_coding_emacs_mule): Abort if there isn't enough place in

11282 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
11283 %llo or %llx format is passed. (Bug#8545)
11285 * window.c (window_scroll_line_based): Use a marker instead of
11286 simple variables to record original value of point. (Bug#7952)
11288 * doprnt.c (doprnt): Fix the case where a multibyte sequence
11289 produced by %s or %c overflows available buffer space. (Bug#8545)
11291 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
11293 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

11318 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
11320 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
11322 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
11324 * makefile.w32-in: Update dependencies.
11326 2011-04-27 Eli Zaretskii <eliz@gnu.org>
11328 Improve `doprnt' and its usage. (Bug#8545)
11329 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
11330 `format_end'. Remove support for %l as a conversion specifier.
11331 Don't use xrealloc. Improve diagnostics when the %l size modifier
11332 is used. Update the commentary.
11334 * eval.c (verror): Simplify calculation of size_t.
11336 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
11339 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
11341 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
11344 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
11346 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
11347 This makes this file independent of the recent pseudovector change.
11349 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
11351 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
11353 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
11354 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
11355 Remove unused local.
11356 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
11358 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
11359 GCC 4.6.0 optimizes based on type-based alias analysis.
11360 For example, if b is of type struct buffer * and v of type struct
11361 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
11362 != &v->size, and therefore "v->size = 1; b->size = 2; return
11363 v->size;" must therefore return 1. This assumption is incorrect
11364 for Emacs, since it type-puns struct Lisp_Vector * with many other
11365 types. To fix this problem, this patch adds a new type struct
11366 vectorlike_header that documents the constraints on layout of vectors
11367 and pseudovectors, and helps optimizing compilers not get fooled
11368 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
11369 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
11370 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
11372 (XSETPVECTYPE): Rewrite in terms of new macro.
11373 (XSETPVECTYPESIZE): New macro, specifying both type and size.
11374 This is a bit clearer, and further avoids the possibility of
11375 undesirable aliasing.
11376 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
11377 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
11378 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
11379 since Lisp_Subr is a special case (no "next" field).
11380 (ASIZE): Now uses header.size rather than size.
11381 All previous uses of XVECTOR (foo)->size replaced to use this macro,
11382 to avoid the hassle of writing XVECTOR (foo)->header.size.
11383 (struct vectorlike_header): New type.
11384 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
11385 object, to help avoid aliasing.
11386 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
11387 (SUBRP): Likewise, since Lisp_Subr is a special case.
11388 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
11389 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
11390 (struct Lisp_Hash_Table): Combine first two members into a single
11391 struct vectorlike_header member. All uses of "size" and "next" members
11392 changed to be "header.size" and "header.next".
11393 * buffer.h (struct buffer): Likewise.
11394 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
11395 * frame.h (struct frame): Likewise.
11396 * process.h (struct Lisp_Process): Likewise.
11397 * termhooks.h (struct terminal): Likewise.
11398 * window.c (struct save_window_data, struct saved_window): Likewise.
11399 * window.h (struct window): Likewise.
11400 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
11401 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
11402 * buffer.c (init_buffer_once): Likewise.
11403 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
11405 * process.c (Fformat_network_address): Use local var for size,
11408 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
11410 Make the Lisp reader and string-to-float more consistent (Bug#8525)
11411 * data.c (atof): Remove decl; no longer used or needed.
11412 (digit_to_number): Move to lread.c.
11413 (Fstring_to_number): Use new string_to_number function, to be
11414 consistent with how the Lisp reader treats infinities and NaNs.
11415 Do not assume that floating-point numbers represent EMACS_INT
11416 without losing information; this is not true on most 64-bit hosts.
11417 Avoid double-rounding errors, by insisting on integers when
11418 parsing non-base-10 numbers, as the documentation specifies.
11419 * lisp.h (string_to_number): New decl, replacing ...
11420 (isfloat_string): Remove.
11421 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
11422 (read1): Do not accept +. and -. as integers; this
11423 appears to have been a coding error. Similarly, do not accept
11424 strings like +-1e0 as floating point numbers. Do not report
11425 overflow for integer overflows unless the base is not 10 which
11426 means we have no simple and reliable way to continue.
11427 Break out the floating-point parsing into a new
11428 function string_to_number, so that Fstring_to_number parses
11429 floating point numbers consistently with the Lisp reader.
11430 (digit_to_number): Move here from data.c. Make it static inline.
11431 (E_CHAR, EXP_INT): Remove, replacing with ...
11432 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
11433 (string_to_number): New function, replacing isfloat_string.
11434 This function checks for valid syntax and produces the resulting
11435 Lisp float number too. Rework it so that string-to-number
11436 no longer mishandles examples like "1.0e+". Use strtoumax,
11437 so that overflow for non-base-10 numbers is reported only when
11438 there's no portable and simple way to convert to floating point.
11440 * textprop.c (set_text_properties_1): Rewrite for clarity,
11441 and to avoid GCC warning about integer overflow.
11443 * intervals.h (struct interval): Use EMACS_INT for members
11444 where EMACS_UINT might cause problems. See
11445 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
11446 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
11447 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
11449 (offset_intervals): Tell GCC not to worry about length overflow
11450 when negating a negative length.
11452 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
11453 (overrun_check_free): Likewise.
11455 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
11456 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
11459 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
11460 (gnutls_make_error): Rename local to avoid shadowing.
11461 (gnutls_emacs_global_deinit): ifdef out; not used.
11462 (Fgnutls_boot): Use const for pointer to readonly storage.
11463 Comment out unused local. Fix pointer signedness problems.
11465 * lread.c (openp): Don't stuff size_t into an 'int'.
11466 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
11467 about possible signed overflow.
11469 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
11470 (GDK_KEY_g): Don't define if already defined.
11471 (xg_prepare_tooltip): Avoid pointer signedness problem.
11472 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
11474 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
11475 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
11477 * xfns.c (Fx_window_property): Simplify a bit,
11478 to make a bit faster and to avoid GCC 4.6.0 warning.
11479 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
11481 * fns.c (internal_equal): Don't assume size_t fits in int.
11483 * alloc.c (compact_small_strings): Tighten assertion a little.
11485 Replace pEd with more-general pI, and fix some printf arg casts.
11486 * lisp.h (pI): New macro, generalizing old pEd macro to other
11487 conversion specifiers. For example, use "...%"pI"d..." rather
11488 than "...%"pEd"...".
11489 (pEd): Remove. All uses replaced with similar uses of pI.
11490 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
11491 * alloc.c (check_pure_size): Don't overflow by converting size to int.
11492 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
11493 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
11494 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
11495 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
11496 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
11498 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
11499 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
11500 * print.c (safe_debug_print, print_object): Likewise.
11501 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
11503 Use pI instead of if-then-else-abort. Use %p to avoid casts,
11504 avoiding the 0 flag, which is not portable.
11505 * process.c (Fmake_network_process): Use pI to avoid cast.
11506 * region-cache.c (pp_cache): Likewise.
11507 * xdisp.c (decode_mode_spec): Likewise.
11508 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
11509 behavior on 64-bit hosts with printf arg.
11510 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
11511 (x_stop_queuing_selection_requests): Likewise.
11512 (x_get_window_property): Don't truncate byte count to an 'int'
11515 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
11516 here, since it parses constructs like leading '-' and spaces,
11517 which are not wanted; and it overflows with large numbers.
11518 Instead, simply match F[0-9]+, which is what is wanted anyway.
11520 * alloc.c: Remove unportable assumptions about struct layout.
11521 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
11522 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
11523 (allocate_vectorlike, make_pure_vector): Use the new macros,
11524 plus offsetof, to remove unportable assumptions about struct layout.
11525 These assumptions hold on all porting targets that I know of, but
11526 they are not guaranteed, they're easy to remove, and removing them
11527 makes further changes easier.
11529 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
11530 This doesn't fix a bug but makes the code clearer.
11531 (string_overrun_cookie): Now const. Use initializers that
11532 don't formally overflow signed char, to avoid warnings.
11533 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
11534 can cause Emacs to crash when string overrun checking is enabled.
11535 (allocate_buffer): Don't assume sizeof (struct buffer) is a
11536 multiple of sizeof (EMACS_INT); it need not be, if
11537 alignof(EMACS_INT) < sizeof (EMACS_INT).
11538 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
11540 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

11547 supposed to be handshaking. (Bug#8556)
11548 Reported by Paul Eggert <eggert@cs.ucla.edu>.
11550 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>

11567 2011-04-25 Eli Zaretskii <eliz@gnu.org>
11569 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
11570 "cast to pointer from integer of different size".
11572 Improve doprnt and its use in verror. (Bug#8545)
11573 * doprnt.c (doprnt): Document the set of format control sequences
11574 supported by the function. Use SAFE_ALLOCA instead of always
11577 * eval.c (verror): Don't limit the buffer size at size_max-1, that
11578 is one byte too soon. Don't use xrealloc; instead xfree and
11581 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
11583 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
11586 * gnutls.c: Renamed global_initialized to
11587 gnutls_global_initialized. Added internals for the
11588 :verify-hostname-error, :verify-error, and :verify-flags
11589 parameters of `gnutls-boot' and documented those parameters in the
11590 docstring. Start callback support.
11591 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
11592 unless a fatal error occurred. Call gnutls_alert_send_appropriate

11665 * doprnt.c: Include limits.h.
11666 (SIZE_MAX): New macro.
11667 (doprnt): Return a size_t value. 2nd arg is now size_t.
11668 Many local variables are now size_t instead of int or unsigned.
11669 Improve overflow protection. Support `l' modifier for integer
11670 conversions. Support %l conversion. Don't assume an EMACS_INT
11671 argument for integer conversions and for %c.
11673 * lisp.h (doprnt): Restore prototype.
11675 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
11676 $(SRC)/character.h.
11678 * Makefile.in (base_obj): Add back doprnt.o.
11680 * deps.mk (doprnt.o): Add back prerequisites.
11681 (callint.o): Depend on character.h.
11683 * eval.c (internal_lisp_condition_case): Include the handler
11684 representation in the error message.

11690 * callint.c (Fcall_interactively): When displaying error message
11691 about invalid control letter, pass the character's codepoint, not
11692 a pointer to its multibyte form. Improve display of the character
11693 in octal and display also its hex code.
11695 * character.c (char_string): Use %x to display the (unsigned)
11696 codepoint of an invalid character, to avoid displaying a bogus
11699 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
11700 `error', not SYMBOL_NAME itself.
11702 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
11703 character arguments to `error'.
11705 * charset.c (check_iso_charset_parameter): Fix incorrect argument
11706 to `error' in error message about FINAL_CHAR argument. Make sure
11707 FINAL_CHAR is a character, and use %c when it is passed as
11708 argument to `error'.

11772 Define only if needed.
11774 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
11775 by pacifying GCC about it. Maybe it's time to retire it?

11778 * dispextern.h (struct redisplay_interface): Rename param
11779 to avoid shadowing.
11780 * termhooks.h (struct terminal): Likewise.
11781 * xterm.c (xembed_send_message): Likewise.
11783 * insdel.c (make_gap_smaller): Define only if
11784 USE_MMAP_FOR_BUFFERS || REL_ALLOC || DOUG_LEA_MALLOC.
11786 * keyboard.c (read_char): Make a var volatile so longjmp won't clobber
11789 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
11790 so that we aren't warned about unused symbols.
11792 * xfns.c (Fx_file_dialog): Rename local to avoid shadowing.
11794 * xdisp.c (x_produce_glyphs): Mark var as initialized (Bug#8512).
11796 * xfns.c (x_real_positions): Mark locals as initialized.

11801 (toolkit_scroll_bar_interaction): Define and use only if USE_X_TOOLKIT.
11802 (x_dispatch_event): Declare static if USE_GTK, and
11803 define if USE_GTK || USE_X_TOOLKIT.
11804 (SET_SAVED_BUTTON_EVENT): Define only if USE_X_TOOLKIT || USE_GTK.
11805 * xterm.h (x_dispatch_event): Extern only if USE_X_TOOLKIT.
11806 * xterm.c, xterm.h (x_mouse_leave): Bring this function back, but only
11807 if defined HAVE_MENUS && !defined USE_X_TOOLKIT && !defined USE_GTK.
11809 * xmenu.c (menu_help_callback): Pointer type fixes.
11810 Use const pointers when pointing at readonly data. Avoid pointer
11811 signedness clashes.

12258 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
12259 * dispextern.h (bidi_dump_cached_states): Remove, since it's
12260 exported only to the debugger.
12262 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
12263 * atimer.h (run_all_atimers): Remove; not exported.
12265 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
12266 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
12267 was inaccessible from Lisp.
12268 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
12269 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
12271 alloc.c: Import and export fewer symbols, and remove unused items.
12272 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
12274 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
12275 it's not optimized away by whole-program optimization.
12276 (message_enable_multibyte, free_misc): Remove.
12277 (catchlist, handlerlist, mark_backtrace):
12278 Declare only if BYTE_MARK_STACK.
12279 (mark_byte_stack): Likewise, fixing a ifdef-vs-if typo.
12280 * alloc.c (pure): Export only if VIRT_ADDR_VARIES is defined.
12281 (message_enable_multibyte): Remove decl.
12282 (free_misc, interval_free_list, float_block, float_block_index):
12283 (n_float_blocks, float_free_list, cons_block, cons_block_index):
12284 (cons_free_list, last_marked_index):
12286 (suppress_checking, die): Define only if ENABLE_CHECKING is defined.
12287 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
12288 (mark_backtrace): Define only if BYTE_MARK_STACK.
12289 * xdisp.c (message_enable_multibyte): Now static.
12291 Declare Lisp_Object Q* variables to be 'static' if not exported.
12292 This makes it easier for human readers (and static analyzers)
12293 to see whether these variables are used from other modules.
12294 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
12295 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
12296 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:
12297 * font.c, frame.c, fringe.c, ftfont.c, image.c, keyboard.c, keymap.c:
12298 * lread.c, macros.c, minibuf.c, print.c, process.c, search.c:
12299 * sound.c, syntax.c, textprop.c, window.c, xdisp.c, xfaces.c, xfns.c:
12300 * xmenu.c, xselect.c:
12301 Declare Q* vars static if they are not used in other modules.
12302 * ccl.h, character.h, charset.h, coding.h, composite.h, font.h:
12303 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
12304 Remove decls of unexported vars.
12305 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
12307 * lisp.h (DEFINE_FUNC): Make sname 'static'.
12309 Make Emacs functions such as Fatom 'static' by default.
12310 This makes it easier for human readers (and static analyzers)
12311 to see whether these functions can be called from other modules.
12312 DEFUN now defines a static function. To make the function external
12313 so that it can be used in other C modules, use the new macro DEFUE.
12314 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
12315 (Finit_image_library):
12316 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
12317 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
12318 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
12319 Remove decls, since these functions are now static.
12320 (Funintern, Fget_internal_run_time): New decls, since these functions
12321 were already external.
12323 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
12324 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:
12325 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, floatfns.c:
12326 * fns.c, font.c, fontset.c, frame.c, image.c, indent.c:
12327 * keyboard.c, keymap.c, lread.c:
12328 * macros.c, marker.c, menu.c, minibuf.c, print.c, process.c, search.c:
12329 * syntax.c, term.c, terminal.c, textprop.c, undo.c:
12330 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
12331 Mark functions with DEFUE instead of DEFUN,
12332 if they are used in other modules.
12333 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
12334 decls for now-static functions.
12335 * buffer.h (Fdelete_overlay): Remove decl.
12336 * callproc.c (Fgetenv_internal): Mark as internal.
12337 * composite.c (Fremove_list_of_text_properties): Remove decl.

12339 * composite.h (Fcomposite_get_gstring): Remove decl.
12340 * dired.c (Ffile_attributes): New forward static decl.
12341 * doc.c (Fdocumntation_property): New forward static decl.
12342 * eval.c (Ffetch_bytecode): New forward static decl.
12343 (Funintern): Remove extern decl; now in .h file where it belongs.
12344 * fileio.c (Fmake_symbolic_link): New forward static decl.
12345 * image.c (Finit_image_library): New forward static decl.
12346 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
12347 * intervals.h (Fprevious_property_change):
12348 (Fremove_list_of_text_properties): Remove decls.
12349 * keyboard.c (Fthis_command_keys): Remove decl.
12350 (Fcommand_execute): New forward static decl.
12351 * keymap.c (Flookup_key): New forward static decl.
12352 (Fcopy_keymap): Now static.
12353 * keymap.h (Flookup_key): Remove decl.
12354 * process.c (Fget_process): New forward static decl.
12355 (Fprocess_datagram_address): Mark as internal.
12356 * syntax.c (Fsyntax_table_p): New forward static decl.
12357 (skip_chars): Remove duplicate decl.
12358 * textprop.c (Fprevious_property_change): New forward static decl.
12359 * window.c (Fset_window_fringes, Fset_window_scroll_bars):
12361 (Fset_window_margins, Fset_window_vscroll): New forward static decls.
12362 * window.h (Fset_window_vscroll, Fset_window_margins): Remove decls.

12366 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
12368 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
12371 2011-04-13 Eli Zaretskii <eliz@gnu.org>
12373 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
12374 when at ZV. (Bug#8487)
12376 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
12378 * charset.c (Fclear_charset_maps): Use xfree instead of free.
12380 * keyboard.c (parse_tool_bar_item): Likewise.
12381 * sound.c (sound_cleanup, alsa_close): Likewise.
12382 * termcap.c (tgetent): Likewise.
12383 * xfns.c (x_default_font_parameter): Likewise.
12384 * xsettings.c (read_and_apply_settings): Likewise.
12386 * alloc.c (overrun_check_malloc, overrun_check_realloc)
12387 (overrun_check_free): Protoize.
12389 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
12391 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
12392 since callers should never pass a negative size.
12393 Change the signature to match that of plain 'read' and 'write'; see
12394 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
12395 * lisp.h: Update prototypes of emacs_write and emacs_read.
12397 2011-04-11 Eli Zaretskii <eliz@gnu.org>
12399 * xdisp.c (redisplay_window): Don't try to determine the character
12400 position of the scroll margin if the window start point w->startp
12401 is outside the buffer's accessible region. (Bug#8468)
12403 2011-04-10 Eli Zaretskii <eliz@gnu.org>
12405 Fix write-region and its subroutines for buffers > 2GB.
12406 * fileio.c (a_write, e_write): Modify declaration of arguments and
12407 local variables to support buffers larger than 2GB.
12408 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
12410 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
12411 argument, local variables, and return value.
12413 * lisp.h: Update prototypes of emacs_write and emacs_read.
12415 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
12417 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
12419 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
12421 Fix more problems found by GCC 4.6.0's static checks.
12423 * xdisp.c (vmessage): Use a better test for character truncation.
12425 * charset.c (load_charset_map): <, not <=, for optimization,
12426 and to avoid potential problems with integer overflow.
12427 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
12428 * casetab.c (set_identity, shuffle): Likewise.
12429 * editfns.c (Fformat): Likewise.
12430 * syntax.c (skip_chars): Likewise.
12432 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
12433 This also lets GCC 4.6.0 generate slightly better loop code.
12435 * callint.c (Fcall_interactively): <, not <=, for optimization.
12436 (Fcall_interactively): Count the number of arguments produced,
12437 not the number of arguments given. This is simpler and lets GCC
12438 4.6.0 generate slightly better code.
12440 * ftfont.c: Distingish more carefully between FcChar8 and char.
12441 The previous code passed unsigned char * to a functions like
12442 strlen and xstrcasecmp that expect char *, which does not
12443 conform to the C standard.
12444 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
12445 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
12446 char * when the C standard requires it.
12448 * keyboard.c (read_char): Remove unused var.
12450 * eval.c: Port to Windows vsnprintf (Bug#8435).
12451 Include <limits.h>.
12452 (SIZE_MAX): Define if the headers do not.
12453 (verror): Do not give up if vsnprintf returns a negative count.
12454 Instead, grow the buffer. This ports to Windows vsnprintf, which
12455 does not conform to C99. Problem reported by Eli Zaretskii.
12456 Also, simplify the allocation scheme, by avoiding the need for
12457 calling realloc, and removing the ALLOCATED variable.
12459 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
12461 Remove invocations of doprnt, as Emacs now uses vsnprintf.
12462 But keep the doprint source code for now, as we might revamp it
12463 and use it again (Bug#8435).
12464 * lisp.h (doprnt): Remove.
12465 * Makefile.in (base_obj): Remove doprnt.o.
12466 * deps.mk (doprnt.o): Remove.
12468 error: Print 32- and 64-bit integers portably (Bug#8435).
12469 Without this change, on typical 64-bit hosts error ("...%d...", N)
12470 was used to print both 32- and 64-bit integers N, which relied on
12471 undefined behavior.
12472 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
12473 * lisp.h (error, verror): Mark as printf-like functions.
12474 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
12475 Report overflow in size calculations when allocating printf buffer.
12476 Do not truncate output string at its first null byte.
12477 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
12478 Truncate the output at a character boundary, since vsnprintf does not
12480 * charset.c (check_iso_charset_parameter): Convert internal
12481 character to string before calling 'error', since %c now has the
12483 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
12484 overflow when computing char to be passed to 'error'. Do not
12485 pass Lisp_Object to 'error'; pass the integer instead.
12486 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
12487 formatted with plain %d.
12489 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
12491 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
12493 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
12495 * xterm.c (x_catch_errors): Remove duplicate declaration.
12497 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
12499 * xdisp.c, lisp.h (message_nolog): Remove; unused.
12501 2011-04-10 Jim Meyering <meyering@redhat.com>
12503 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
12504 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
12505 return ssize_t not "int", and use size_t as the buffer length.
12506 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
12507 * gnutls.h: Update declarations.
12508 * process.c (read_process_output): Use ssize_t, to match.
12509 (send_process): Likewise.
12511 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
12513 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
12515 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
12517 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
12518 Use unsigned char, to match FcChar8 type definition.
12520 * xterm.c (handle_one_xevent):
12521 * xmenu.c (create_and_show_popup_menu):
12522 * xselect.c (x_decline_selection_request)
12523 (x_reply_selection_request): Avoid type-punned deref of X events.
12525 2011-04-09 Eli Zaretskii <eliz@gnu.org>
12527 Fix some uses of `int' instead of EMACS_INT.
12528 * search.c (string_match_1, fast_string_match)
12529 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
12530 (scan_buffer, find_next_newline_no_quit)
12531 (find_before_next_newline, search_command, Freplace_match)
12532 (Fmatch_data): Make some `int' variables be EMACS_INT.
12534 * xdisp.c (display_count_lines): 3rd argument and return value now
12535 EMACS_INT. All callers changed.
12536 (pint2hrstr): Last argument is now EMACS_INT.
12538 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
12539 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
12540 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
12541 (decode_coding_utf_16, decode_coding_emacs_mule)
12542 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
12543 (decode_coding_ccl, decode_coding_charset)
12544 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
12545 (decode_coding_iso_2022, decode_coding_emacs_mule)
12546 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
12547 <char_offset, last_offset>: Declare EMACS_INT.
12548 (encode_coding_utf_8, encode_coding_utf_16)
12549 (encode_coding_emacs_mule, encode_invocation_designation)
12550 (encode_designation_at_bol, encode_coding_iso_2022)
12551 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
12552 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
12554 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
12555 (encode_invocation_designation): Last argument P_NCHARS is now
12557 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
12558 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
12560 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
12563 * ccl.c (Fccl_execute_on_string): Declare some variables
12566 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
12568 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
12570 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
12572 * process.c (Fformat_network_address): Doc fix.
12574 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
12576 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
12578 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
12580 * keyboard.c (read_char): Call Lisp function help-form-show,
12581 instead of using internal_with_output_to_temp_buffer.
12582 (Qhelp_form_show): New var.
12583 (syms_of_keyboard): Use DEFSYM macro.
12585 * print.c (internal_with_output_to_temp_buffer): Function deleted.
12587 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
12589 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
12591 * process.c (Flist_processes): Remove to Lisp.
12592 (list_processes_1): Delete.
12594 2011-04-06 Eli Zaretskii <eliz@gnu.org>
12596 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
12598 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
12600 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
12602 Fix more problems found by GCC 4.6.0's static checks.
12604 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
12606 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
12608 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
12610 * xdisp.c (vmessage): Mark as a printf-like function.
12612 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
12614 * sound.c (sound_warning): Don't crash if arg contains a printf format.
12616 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
12617 printf-like functions.
12618 (tiff_load): Add casts to remove these marks before passing them
12619 to system-supplied API.
12621 * eval.c (Fsignal): Remove excess argument to 'fatal'.
12623 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
12624 This avoids several warnings with gcc -Wstrict-overflow.
12625 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
12626 directly, rather than having caller test rule sign. This avoids
12627 some unnecessary tests.
12628 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
12629 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
12630 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
12632 * xfont.c (xfont_text_extents): Remove var that was set but not used.
12633 (xfont_open): Avoid unnecessary tests.
12635 * composite.c (composition_gstring_put_cache): Use unsigned integer.
12637 * composite.h, composite.c (composition_gstring_put_cache):
12638 Use EMACS_INT, not int, for length.
12640 * composite.h (COMPOSITION_DECODE_REFS): New macro,
12641 breaking out part of COMPOSITION_DECODE_RULE.
12642 (COMPOSITION_DECODE_RULE): Use it.
12643 * composite.c (get_composition_id): Remove unused local vars,
12644 by using the new macro.
12646 * textprop.c (set_text_properties_1): Change while to do-while,
12647 since the condition is always true at first.
12649 * intervals.c (graft_intervals_into_buffer): Mark var as used.
12650 (interval_deletion_adjustment): Return unsigned value.
12653 * process.c (list_processes_1, create_pty, read_process_output):
12654 (exec_sentinel): Remove vars that were set but not used.
12655 (create_pty): Remove unnecessary "volatile"s.
12656 (Fnetwork_interface_info): Avoid possibility of int overflow.
12657 (read_process_output): Do adaptive read buffering even if carryover.
12658 (read_process_output): Simplify nbytes computation if buffered.
12660 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
12662 * syntax.c (scan_words): Remove var that was set but not used.
12663 (update_syntax_table): Use unsigned instead of int.
12665 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
12666 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
12667 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
12669 * print.c (print_error_message): Avoid int overflow.
12671 * font.c (font_list_entities): Redo for clarity,
12672 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
12674 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
12675 (font_score): Avoid potential overflow in diff calculation.
12677 * fns.c (substring_both): Remove var that is set but not used.
12678 (sxhash): Redo loop for clarity and to avoid wraparound warning.
12680 * eval.c (funcall_lambda): Rename local to avoid shadowing.
12682 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
12683 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
12684 can always succeed if overflow has undefined behavior.

12694 * dired.c (file_name_completion): Remove var that is set but not used.
12696 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
12698 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
12699 (Finsert_file_contents): Remove unnecessary code checking fd.
12701 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
12702 Check for integer overflow on size calculations.
12704 * buffer.c (Fprevious_overlay_change): Remove var that is set
12707 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
12708 Remove vars that are set but not used.
12709 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
12710 (timer_check_2): Mark vars as initialized.

12714 * image.c (lookup_image): Remove var that is set but not used.
12715 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
12717 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
12718 that are set but not used.
12720 * xfns.c (make_invisible_cursor): Don't return garbage
12721 if XCreateBitmapFromData fails (Bug#8410).
12723 * xselect.c (x_get_local_selection, x_handle_property_notify):
12724 Remove vars that are set but not used.
12726 * xfns.c (x_create_tip_frame): Remove var that is set but not used.

12730 Remove var that is set but not used.
12731 (scroll_bar_windows_size): Now size_t, not int.
12732 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
12733 Check for overflow.
12735 * xfaces.c (realize_named_face): Remove vars that are set but not used.
12736 (map_tty_color) [!defined MSDOS]: Likewise.
12738 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
12740 * coding.c: Remove vars that are set but not used.
12741 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
12742 All callers changed.

12750 * print.c (print_object): Remove var that is set but not used.
12752 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
12753 The gnulib version avoids calling malloc in the usual case,
12754 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
12755 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
12756 * filelock.c (current_lock_owner): Likewise.
12757 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
12758 * sysdep.c: Include allocator.h, careadlinkat.h.
12759 (emacs_no_realloc_allocator): New static constant.
12760 (emacs_readlink): New function.
12761 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
12762 ../lib/careadlinkat.h.
12764 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
12766 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the

12788 do not dereference NULL upon failed strdup
12789 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
12790 (ns_get_family): Likewise.
12792 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
12794 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
12796 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
12798 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
12801 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
12803 Add lexical binding.

12814 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
12816 (syms_of_lread): Declare `lexical-binding'.
12818 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
12820 * keyboard.c (eval_dyn): New fun.
12821 (menu_item_eval_property): Use it.
12823 * image.c (parse_image_spec): Use Ffunctionp.
12825 * fns.c (concat, mapcar1): Accept byte-code-functions.
12827 * eval.c (Fsetq): Handle lexical vars.
12828 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
12829 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
12830 (FletX, Flet): Obey lexical binding.
12831 (Fcommandp): Handle closures.
12832 (Feval): New `lexical' arg.
12833 (eval_sub): New function extracted from Feval. Use it almost
12834 everywhere where Feval was used. Look up vars in lexical env.
12836 (Ffunctionp): Move from subr.el.
12837 (Ffuncall): Handle closures.
12838 (apply_lambda): Remove `eval_flags'.
12839 (funcall_lambda): Handle closures and new byte-code-functions.
12840 (Fspecial_variable_p): New function.
12841 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
12842 but without exporting it to Lisp.
12844 * doc.c (Fdocumentation, store_function_docstring):
12845 * data.c (Finteractive_form): Handle closures.
12847 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
12850 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
12852 (exec_byte_code): New function extracted from Fbyte_code to handle new
12853 calling convention for byte-code-functions. Add new byte-codes.
12855 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
12857 * alloc.c (Fmake_symbol): Init new `declared_special' field.
12859 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
12861 * xdisp.c (redisplay_internal): Fix prototype.
12863 2011-03-31 Eli Zaretskii <eliz@gnu.org>
12865 * xdisp.c (SCROLL_LIMIT): New macro.
12866 (try_scrolling): Use it when setting scroll_limit.
12867 Limit scrolling to 100 screen lines.
12868 (redisplay_window): Even when falling back on "recentering",
12869 position point in the window according to scroll-conservatively,
12870 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
12872 (try_scrolling): When point is above the window, allow searching
12873 as far as scroll_max, or one screenful, to compute vertical
12874 distance from PT to the scroll margin position. This prevents
12875 try_scrolling from unnecessarily failing when
12876 scroll-conservatively is set to a value slightly larger than the
12877 window height. Clean up the case of PT below the margin at bottom
12878 of window: scroll_max can no longer be INT_MAX. When aggressive
12879 scrolling is in use, don't let point enter the opposite scroll
12880 margin as result of the scroll.
12881 (syms_of_xdisp) <scroll-conservatively>: Document the
12882 threshold of 100 lines for never-recentering scrolling.

12889 (message_log_check_duplicate): Remove parameters `prev_bol' and
12890 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
12891 (redisplay_internal): Remove parameter `preserve_echo_area',
12892 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
12894 * indent.c (Fvertical_motion):
12895 * window.c (window_scroll_pixel_based, Frecenter):
12896 Don't pass `need_y_p' to `move_it_by_lines'.
12898 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
12900 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
12901 steal a few bits to be more compact.
12902 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
12903 Remove unneeded casts.
12905 * bytecode.c (Fbyte_code): CAR and CDR can GC.
12907 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
12909 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
12910 binding" message (bug#7967).
12912 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
12914 Fix more problems found by GCC 4.6.0's static checks.
12916 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
12917 Remove unused local var.
12919 * editfns.c (Fmessage_box): Remove unused local var.
12921 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
12922 (note_mode_line_or_margin_highlight, note_mouse_highlight):
12923 Omit unused local vars.
12924 * window.c (shrink_windows): Omit unused local var.
12925 * menu.c (digest_single_submenu): Omit unused local var.
12926 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
12927 Omit unused local var.
12929 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
12930 Don't assume string length fits in int.
12931 (keyremap_step, read_key_sequence): Use size_t for sizes.

12935 instead of alloca (Bug#8344).
12937 * eval.c (Fbacktrace): Don't assume nargs fits in int.
12938 (Fbacktrace_frame): Don't assume nframes fits in int.
12940 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

12945 * term.c (produce_glyphless_glyph): Remove unnecessary test.
12947 * cm.c (calccost): Turn while-do into do-while, for clarity.
12949 * keyboard.c (syms_of_keyboard): Use the same style as later
12950 in this function when indexing through an array. This also
12951 works around GCC bug 48267.
12953 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
12955 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
12957 * chartab.c (sub_char_table_ref_and_range): Redo for slight
12958 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
12960 * keyboard.c, keyboard.h (num_input_events): Now size_t.
12961 This avoids undefined behavior on integer overflow, and is a bit
12962 more convenient anyway since it is compared to a size_t variable.
12964 Variadic C functions now count arguments with size_t, not int.
12965 This avoids an unnecessary limitation on 64-bit machines, which
12966 caused (substring ...) to crash on large vectors (Bug#8344).

12976 * fns.c (concat): Likewise.
12977 * frame.c (x_set_frame_parameters): Likewise.
12978 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
12979 0 if not found, not -1. All callers changed.
12981 * alloc.c (garbage_collect): Don't assume stack size fits in int.
12982 (stack_copy_size): Now size_t, not int.
12983 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
12985 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
12987 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
12988 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

12992 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
12993 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

13004 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
13005 don't set the hook to nil, but remove the offending function instead.
13006 (Qcommand_hook_internal): Remove, unused.
13007 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
13008 Vcommand_hook_internal.

13011 (funcall_nil, funcall_not): New functions.
13012 (run_hook_with_args): Call each function through a `funcall' argument.

13026 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.

13147 Remove unused variable `width'.
13149 2011-03-24 Juanma Barranquero <lekktu@gmail.com>
13151 * w32term.c (x_set_glyph_string_clipping):
13152 Don't pass uninitialized region to CombineRgn.
13154 2011-03-23 Juanma Barranquero <lekktu@gmail.com>
13156 * w32fns.c (x_set_menu_bar_lines): Remove unused variable `olines'.

13176 2011-03-23 Julien Danjou <julien@danjou.info>
13178 * term.c (Fsuspend_tty, Fresume_tty):
13179 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
13180 * window.c (temp_output_buffer_show):
13181 * insdel.c (signal_before_change):
13182 * frame.c (Fhandle_switch_frame):
13183 * fileio.c (Fdo_auto_save):

13186 * cmds.c (internal_self_insert):
13187 * callint.c (Fcall_interactively):
13188 * buffer.c (Fkill_all_local_variables):
13189 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
13191 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
13192 unconditionally since it does the check itself.
13194 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
13196 Fix more problems found by GCC 4.5.2's static checks.
13198 * coding.c (encode_coding_raw_text): Avoid unnecessary test
13199 the first time through the loop, since we know p0 < p1 then.
13200 This also avoids a gcc -Wstrict-overflow warning.
13202 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
13203 leading to a memory leak, possible in functions like
13204 load_charset_map_from_file that can allocate an unbounded number
13205 of objects (Bug#8318).
13207 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
13208 that could (at least in theory) be that large.
13210 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
13211 This is less likely to overflow, and avoids undefined behavior if
13212 overflow does occur. All callers changed. Use strtoul to scan
13213 for the unsigned long integer.
13214 (pint2hrstr): Simplify and tune code slightly.
13215 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
13217 * scroll.c (do_scrolling): Work around GCC bug 48228.
13218 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.

13221 This also avoids a warning with gcc -Wstrict-overflow.
13222 (validate_x_resource_name): Simplify count usage.
13223 This also avoids a warning with gcc -Wstrict-overflow.
13225 * fileio.c (Fcopy_file): Report error if fchown or fchmod
13228 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
13230 * process.c (Fmake_network_process): Use socklen_t, not int,
13231 where POSIX says socklen_t is required in portable programs.
13232 This fixes a porting bug on hosts like 64-bit HP-UX, where
13233 socklen_t is wider than int (Bug#8277).
13234 (Fmake_network_process, server_accept_connection):
13235 (wait_reading_process_output, read_process_output):
13238 * process.c: Rename or move locals to avoid shadowing.

13248 Make tparam.h and terminfo.c consistent.
13249 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
13250 Include tparam.h instead, since it declares them.
13251 * cm.h (PC): Remove extern decl; tparam.h now does this.
13252 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
13253 * terminfo.c: Include tparam.h, to check interfaces.
13254 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
13255 (tparam): Adjust signature to match interface in tparam.h;
13256 this removes some undefined behavior. Check that outstring and len
13257 are zero, which they always are with Emacs.
13258 * tparam.h (PC, BC, UP): New extern decls.
13260 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
13261 (xftfont_open): Rename locals to avoid shadowing.
13263 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
13264 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
13265 (OTF_TAG_SYM): Omit macro if not needed.

13273 * xml.c (make_dom): Now static.
13275 * composite.c (composition_compute_stop_pos): Rename local to
13277 (composition_reseat_it): Remove unused locals.
13278 (find_automatic_composition, composition_adjust_point): Likewise.
13279 (composition_update_it): Mark var as initialized.
13280 (find_automatic_composition): Mark vars as initialized,
13281 with a FIXME (Bug#8290).

13284 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
13285 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
13286 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
13287 (BUF_DEC_POS): Be more systematic about renaming local temporaries
13288 to avoid shadowing.
13290 * textprop.c (property_change_between_p): Remove; unused.
13292 * intervals.c (interval_start_pos): Now static.
13294 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

13297 Rename locals to avoid shadowing.
13299 * sound.c (wav_play, au_play, Fplay_sound_internal):
13300 Fix pointer signedness.
13301 (alsa_choose_format): Remove unused local var.
13302 (wav_play): Initialize a variable to 0, to prevent undefined
13303 behavior (Bug#8278).
13305 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
13307 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
13309 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
13310 clobbering (Bug#8298).
13311 * sysdep.c (sys_subshell): Likewise.
13312 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
13314 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
13315 This should get cleaned up, so that child_setup has the
13316 same signature on all platforms.
13318 * callproc.c (call_process_cleanup): Now static.
13319 (relocate_fd): Rename locals to avoid shadowing.
13321 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
13323 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
13324 not to be necessary, and produces flickering.
13326 2011-03-20 Glenn Morris <rgm@gnu.org>
13328 * config.in: Remove file.
13330 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
13332 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
13333 are now in src/globals.h.
13334 (syms_of_minibuf): Remove spurious & from previous change.
13336 2011-03-20 Leo Liu <sdl.web@gmail.com>
13338 * minibuf.c (completing-read-function): New variable.
13339 (completing-read-default): Rename from completing-read.
13340 (completing-read): Call completing-read-function.
13342 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
13344 * xfaces.c (Fx_load_color_file):
13345 Read color file from absolute filename (bug#8250).
13347 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
13349 * makefile.w32-in: Update dependencies.
13351 2011-03-17 Eli Zaretskii <eliz@gnu.org>
13353 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

13360 (sigchld_handler): Now static.
13362 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
13363 That way, the code declares only the vars that it needs.
13364 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
13365 * s/cygwin.h (PTY_ITERATION): Likewise.
13366 * s/darwin.h (PTY_ITERATION): Likewise.

13373 (CONSTANTLIM): Remove; unused.
13374 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
13375 Define only if needed.
13377 * unexelf.c (unexec): Name an expression,
13378 to avoid gcc -Wbad-function-cast warning.
13379 Use a different way to cause a compilation error if anyone uses
13380 n rather than nn, a way that does not involve shadowing.
13381 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
13383 * deps.mk (unexalpha.o): Remove; unused.
13385 New file unexec.h, the (simple) interface for unexec (Bug#8267).
13386 * unexec.h: New file.
13387 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
13388 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
13389 Depend on unexec.h.
13390 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
13391 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
13392 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
13393 Change as necessary to match prototype in unexec.h.
13395 * syntax.c (Fforward_comment, scan_lists): Rename locals to avoid
13397 (back_comment, skip_chars): Mark vars as initialized.

13412 (font_sort_entities): Mark var as initialized.
13414 * character.h (FETCH_CHAR_ADVANCE): Rename locals to avoid shadowing.
13416 * font.c (font_unparse_xlfd): Don't mix pointers to variables with

13440 * callint.c (quotify_arg, quotify_args): Now static.
13441 (Fcall_interactively): Rename locals to avoid shadowing.
13442 Use const pointer when appropriate.

13448 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
13449 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
13450 some of which prompt warnings from gcc -Wbad-function-cast.
13451 (Fformat_time_string, Fencode_time, Finsert_char):
13452 (Ftranslate_region_internal, Fformat):
13453 Rename or remove local vars to avoid shadowing.
13454 (Ftranslate_region_internal): Mark var as initialized.
13456 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
13459 * lisp.h (eassert): Check that the argument compiles, even if
13460 ENABLE_CHECKING is not defined.
13462 * data.c (Findirect_variable): Name an expression, to avoid
13463 gcc -Wbad-function-cast warning.

13472 Rename locals to avoid shadowing.
13473 (mark_stack): Move local variables into the #ifdef region where
13475 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
13476 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
13478 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
13479 (GC_STRING_CHARS): Remove; not used.
13480 (Fmemory_limit): Cast sbrk's returned value to char *.
13482 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
13483 avoids undefined behavior in theory.
13485 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.

13488 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
13489 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
13490 to use the following functions instead of these macros.
13491 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
13492 EMACS_INT, since callers assume the returned value fits in int.
13493 (upcase1): Likewise, for UPCASE_TABLE.
13494 (uppercasep, lowercasep, upcase): New static inline functions.
13495 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
13496 the race-condition problem in the old DOWNCASE.
13498 * regex.c (CHARSET_LOOKUP_RANGE_TABLE_RAW, POP_FAILURE_REG_OR_COUNT):
13499 Rename locals to avoid shadowing.
13500 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
13501 (regex_compile, re_search_2, re_match_2_internal):
13502 Remove unused local vars.
13503 (FREE_VAR): Rewrite so as not to use empty "else",
13504 which gcc can warn about.
13505 (regex_compile, re_match_2_internal): Mark locals as initialized.
13506 (RETALLOC_IF): Define only if needed.
13507 (WORDCHAR_P): Likewise. This one is never needed, but is used
13508 only in a comment talking about a compiler bug, so put inside
13509 the #if 0 of that comment.
13510 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
13511 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
13514 * search.c (boyer_moore): Rename locals to avoid shadowing.
13515 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
13516 (PREV_CHAR_BOUNDARY): Likewise.
13518 * search.c (simple_search): Remove unused var.
13520 * dired.c (compile_pattern): Move decl from here ...

13526 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
13528 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
13529 Rename locals to avoid shadowing.
13530 (Fvertical_motion): Mark locals as initialized.
13532 * casefiddle.c (casify_object, casify_region): Now static.
13533 (casify_region): Mark local as initialized.
13535 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
13537 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
13538 New macros, so that the caller can use some names other than
13539 gcpro1, gcpro2, etc.
13540 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
13542 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
13543 argument, for consistency with GCPRO2_VAR, etc: it is now the
13544 prefix of the variable, not the variable itself. All uses
13546 * dired.c (directory_files_internal, file_name_completion):
13547 Rename locals to avoid shadowing.
13549 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
13550 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
13551 dired.c's scmp function, had undefined behavior.
13552 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
13553 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
13554 * buffer.h: ... to here, because these macros use current_buffer,
13555 and the new implementation with inline functions needs to have
13556 current_buffer in scope now, rather than later when the macros
13558 (downcase, upcase1): New static inline functions.
13559 (DOWNCASE, UPCASE1): Reimplement using these functions.
13560 This avoids undefined behavior in expressions like
13561 DOWNCASE (x) == DOWNCASE (y), which previously suffered
13562 from race conditions in accessing the global variables
13563 case_temp1 and case_temp2.
13564 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
13565 * lisp.h (case_temp1, case_temp2): Remove their decls.
13566 * character.h (ASCII_CHAR_P): Move from here ...
13567 * lisp.h: ... to here, so that the inline functions mentioned
13568 above can use them.
13570 * dired.c (directory_files_internal_unwind): Now static.
13572 * fileio.c (file_name_as_directory, directory_file_name):
13573 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
13575 (file_name_as_directory): Use const pointers when appropriate.

14001 * cm.c (cmgoto): Mark variables that gcc -Wuninitialized does not
14002 deduce are never used uninitialized.

14011 Move these decls to tparam.h, and make them agree with what
14012 is actually in tparam.c. The previous trick of using incompatible
14013 decls in different modules does not conform to the C standard.
