500 glyph. Improve commentary.
501 (display_line): Fix display of continuation glyphs on GUI frames
502 when the right fringe is turned off and variable-size fonts are
503 used in the window. Move the code that appends a stretch glyph to
504 produce_special_glyphs, so that it could be used for truncation
505 and continuation glyphs alike.
506 (produce_special_glyphs) [HAVE_WINDOW_SYSTEM]: Produce a stretch
507 glyph of a suitably computed width, to align the special glyphs at
508 the window margin. Code moved from display_line. (Bug#11832)

688 The functional style also makes code easier to read and maintain.
689 * systime.h: Include <sys/time.h> on all hosts, not just if
690 WINDOWSNT, since 'struct timeval' is needed in general.
691 (EMACS_TIME): Now a typedef, not a macro.

706 (add_emacs_time, sub_emacs_time): New functions.
707 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.

731 Prefer snprintf to strncpy.
732 * nsterm.m (ns_term_init):
733 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
734 * nsterm.m (ns_term_init):
735 Avoid the need for strncpy, by using build_string or
736 make_unibyte_string directly. Use dtoastr, not snprintf.
737 * process.c (Fmake_network_process): Diagnose service names that
738 are too long, rather than silently truncating them or creating
739 non-null-terminated names.
740 (Fnetwork_interface_info): Likewise, for interface names.
741 * sysdep.c (system_process_attributes) [GNU_LINUX]:
742 Prefer sprintf to strncat.

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

769 Optimize pure C strings initialization.
770 * lisp.h (make_pure_string): Fix prototype.
771 (build_pure_c_string): New function, defined as static inline. This
772 provides a better opportunity to optimize away calls to strlen when
773 the function is called with compile-time constant argument.
774 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
775 argument, adjust users accordingly. Use build_pure_c_string where

795 swap 1st and 2nd arguments to obey the common convention. Adjust
797 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
799 2012-07-10 Glenn Morris <rgm@gnu.org>

812 O_RDONLY already includes it).
814 Stop ns builds setting the EMACSLOADPATH environment variable.
815 * nsterm.m (ns_load_path): Rename from ns_init_paths.
816 Now it does not set EMACSLOADPATH, just returns the load-path string.

818 * lread.c [HAVE_NS]: Include nsterm.h.
819 (init_lread) [HAVE_NS]: Use ns_load_path.

822 2012-07-09 Glenn Morris <rgm@gnu.org>
824 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
825 since the included bsd-common.h does so.
827 Stop ns builds setting the EMACSPATH environment variable.
828 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
829 (ns_init_paths): Do not set EMACSPATH.
830 * nsterm.h (ns_exec_path): Add it.
831 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
834 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.

889 Move marker debugging code under MARKER_DEBUG.
890 * marker.c (MARKER_DEBUG): Move marker debugging code under
891 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
892 for bootstrap with --enable-checking (~3x slowdown reported
893 by Juanma Barranquero <lekktu@gmail.com>).
894 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
896 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>

907 (produce_special_glyphs): Move here from term.c.
909 * term.c (produce_special_glyphs): Move to xdisp.c.

946 * lread.c (load_path_check): New function, split from init_lread.
947 (init_lread): Reorganize. Motivation:
948 If EMACSLOADPATH is set, check/warn about that rather than the
949 defaults, which we are not going to use. Hence we can remove
950 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
951 Don't warn if site-lisp directories are missing.
952 If not installed, start from a blank load-path, since
953 PATH_LOADSEARCH refers to the eventual installation directories.

957 Support truncation and continuation glyphs on GUI frames, when
958 fringes are disabled. (Bug#11832)
959 * xdisp.c (init_iterator): Get dimensions of truncation and
960 continuation glyphs even if on GUI frames. Adjust
961 it->last_visible_x on GUI frames when the left or right fringes,
963 (start_display, move_it_in_display_line_to): Handle the case of a
964 GUI frame without a fringe to display continuation or truncation
966 (insert_left_trunc_glyphs): Support GUI frames: make sure
967 truncation glyphs overwrite enough glyphs from the current line to
968 have sufficient space in pixels.
969 (display_line): Support truncation and continuation glyphs on GUI
970 frames. If some spare pixels are left on the line after inserting
971 the truncation glyphs, fill that space with a stretch glyph of a
972 suitably computed width.
974 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
975 produce_glyphs, to support GUI sessions.
977 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
979 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
981 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
983 Do not require float-time's arg to fit in time_t (Bug#11825).
984 This works better on hosts where time_t is unsigned, and where
985 float-time is applied to the (negative) difference between two times.
986 * editfns.c (decode_time_components): Last arg is now double *,
987 not int *, and means to store all the result as a double, without
988 worrying about whether the seconds part fits in time_t.
990 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
992 (Ffloat_time): Do not fail merely because the specified time falls
993 outside of time_t range.
995 2012-07-07 Glenn Morris <rgm@gnu.org>
997 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

1008 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1010 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
1011 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
1012 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
1013 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
1014 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.

1017 * xfont.c (compare_font_names): Redo to omit the need for casts.
1019 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
1021 * xfns.c (Fx_change_window_property): Doc fix.
1022 * w32fns.c (Fx_change_window_property): Doc fix.
1024 * w32fns.c (Fx_window_property): Accept the same arguments as the
1025 X Windows version. Doc fix.
1026 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
1028 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
1029 Eli Zaretskii <eliz@gnu.org>
1031 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
1032 Windows-specific code from nt/config.nt moved here.
1033 Obsolete settings removed.
1035 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1037 * process.c: Avoid unnecessary calls to gettime.
1038 (wait_reading_process_output): Don't get the time of day
1039 when gobbling data immediately and not waiting, as there's no need
1040 for it in that case. This removes a FIXME.
1042 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
1044 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
1045 is defined (Bug#11768).
1047 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1049 Fix marker debugging code.
1050 * marker.c (byte_char_debug_check): Do not perform the check
1051 if buffer is not multibyte.
1052 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
1053 Call byte_char_debug_check with correct arguments.
1055 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1057 Compile marker debugging code only if ENABLE_CHECKING is defined.
1058 * marker.c (byte_char_debug_check, count_markers):
1059 Use only if ENABLE_CHECKING is defined.
1060 (byte_debug_flag): Remove.
1061 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
1062 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
1064 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1066 Avoid code repetition in marker-related functions.
1067 * marker.c (attach_marker): New function.
1068 (Fset_marker, set_marker_restricted, set_marker_both)
1069 (set_marker_restricted_both): Use it.
1070 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
1071 Consistently rename charno to charpos.
1072 (marker_position): Add eassert.
1073 (marker_byte_position): Convert to eassert.
1075 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

1085 * lisp.h (build_marker): New prototype.
1086 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
1087 * composite.c (autocmp_chars): Likewise.
1088 * editfns.c (buildmark): Remove.
1089 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
1090 (save_restriction_save): Use build_marker.
1091 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
1092 * window.c (save_window_save): Likewise.
1094 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1096 Do not use Fdelete_overlay in delete_all_overlays
1097 to avoid redundant calls to unchain_overlay.
1098 * buffer.c (drop_overlay): New function.
1099 (delete_all_overlays, Fdelete_overlay): Use it.
1100 * minibuf.c (get_minibuffer): Fix comment.
1102 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1104 Port to OpenBSD 5.1 amd64.
1105 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
1106 This is needed for OpenBSD, and should be harmless on all BSD systems.
1107 Also, include <sys/sysctl.h>, as it should be available on all
1108 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
1109 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
1110 use p_pid member, not kp_proc.pid.
1112 2012-07-06 Glenn Morris <rgm@gnu.org>
1114 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
1116 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
1118 More xmalloc and related cleanup.
1119 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:

1126 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
1127 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
1129 Omit needless casts involving void * pointers and allocation.
1130 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
1131 as the former is more robust if P's type is changed.
1132 Prefer xzalloc to xmalloc + memset 0.
1133 Simplify malloc-or-realloc to realloc.
1134 Don't worry about xmalloc returning a null pointer.
1135 Prefer xstrdup to xmalloc + strcpy.
1136 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
1138 * keyboard.c (apply_modifiers_uncached): Prefer local array to
1139 alloca of a constant.
1141 2012-07-05 Eli Zaretskii <eliz@gnu.org>
1143 * xdisp.c (display_line): Fix horizontal pixel coordinates when
1144 hscroll is larger than the line width. Fixes long and futile
1145 looping inside extend_face_to_end_of_line (on a TTY) producing
1146 glyphs that are not needed and thrown away.
1148 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
1150 * marker.c (set_marker_restricted_both): Simplify by using
1153 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
1155 * editfns.c (region_limit): Simplify by using clip_to_bounds.

1162 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
1163 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
1164 followed by gtk_box_set_homogeneous (Bug#11768).
1165 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
1166 (update_theme_scrollbar_width, xg_create_scroll_bar):
1167 Use gtk_scrollbar_new (Bug#11768).
1168 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
1169 (is_box_type): New function (Bug#11768).
1170 (xg_tool_item_stale_p): Call is_box_type.
1171 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
1172 with default display (Bug#11768).
1174 2012-07-05 Eli Zaretskii <eliz@gnu.org>
1176 * xdisp.c (window_hscroll_limited): New function.
1177 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
1178 coordinates when window's hscroll is set to insanely large
1181 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
1183 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

1244 * fileio.c (time_error_value): Check the right error number.
1245 Problem reported by Troels Nielsen in
1246 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
1248 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1250 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
1251 This should be fixed in a better way; see Eli Zaretskii in
1252 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
1253 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
1255 * fileio.c (time_error_value): Rename from special_mtime.
1256 The old name's problems were noted by Eli Zaretskii in
1257 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
1259 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
1260 This variable's comment says Emacs needs at least one GDB-visible
1261 symbol of type enum pvec_type, to work around GDB problems.
1262 The symbol's value doesn't matter.
1264 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
1265 that causes compilation to fail on pre-C99 compilers.
1267 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
1269 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

1278 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
1280 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
1281 * lisp.h (enum pvec_type): Use fewer bits.
1282 (PSEUDOVECTOR_SIZE_BITS): New constant.
1283 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
1284 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
1285 change in pvec_type.

1290 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
1291 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
1292 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
1293 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
1294 (sweep_vectors): Use it. Use local var `total_bytes' instead of
1295 abusing vector->header.next.nbytes.
1296 (live_vector_p): Use PVEC_TYPE.
1297 (mark_object): Adapt code to extract pvectype. Use switch.
1299 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1301 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
1302 Tighten new eassert a bit.
1304 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
1306 Fix compilation with --enable-gcc-warnings and -O1
1308 * doprnt.c (doprnt): Change type of tem to int, initialize
1309 to avoid compiler warning. Add eassert.
1310 * search.c (simple_search): Initialize match_byte to avoid
1311 compiler warning. Add eassert.
1313 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1315 Avoid weird behavior with large horizontal scrolls.
1316 Without this change, for example, large hscroll values would
1317 mess up Emacs's display on Fedora 15 x86, presumably due to
1318 overflows in int calculations in the display code.
1319 Also, if buffers had long lines, Emacs would freeze.
1320 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
1321 (set_window_hscroll): New function, containing the old guts of
1322 Fset_window_hscroll. Return the clipped value.
1323 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
1324 This avoids the need to check against PTRDIFF_MAX.
1326 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
1328 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
1330 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
1332 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1334 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
1335 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
1336 since GCC 4.4.6 issues a bogus warning for them.
1338 Fix bugs in file timestamp newness comparisons.
1339 * fileio.c (Ffile_newer_than_file_p):
1340 * lread.c (Fload): Use full timestamp resolution of files,
1341 not just the 1-second resolution, so that files that are only
1342 slightly newer still count as newer.
1343 * fileio.c (Ffile_newer_than_file_p): Don't assume file
1344 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
1346 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
1348 * fileio.c: Improve handling of file time marker. (Bug#11852)
1349 (special_mtime): New function.
1350 (Finsert_file_contents, Fverify_visited_file_modtime):
1351 Use it to set special mtime values consistently.
1353 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
1355 * fileio.c (Finsert_file_contents): Properly handle st_mtime
1356 marker for non-existing file. (Bug#11852)
1358 2012-07-03 Glenn Morris <rgm@gnu.org>
1360 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
1361 and did not make it into globals.h).
1363 2012-07-03 Tom Tromey <tromey@redhat.com>

1401 2012-07-03 Glenn Morris <rgm@gnu.org>
1403 * lisp.h (Frandom): Make it visible to C.
1404 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
1405 buffer for invisible buffers. (Bug#1229)

1409 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
1410 values which aren't power of 2.
1411 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro. Verify
1412 it's value and the value of VECTOR_BLOCK_SIZE. Adjust users

1417 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
1419 * alloc.c (mark_object): Revert part of last patch to use `switch'.
1421 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
1423 * alloc.c (allocate_vector_block): Remove redundant
1424 calls to mallopt if DOUG_LEA_MALLOC is defined.
1425 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
1426 avoid calls to mallopt if zero_vector is returned.
1428 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
1430 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
1431 is enabled, avoid dereferencing NULL current_sblock if
1434 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
1436 Cleanup basic buffer management.
1437 * buffer.h (struct buffer): Change layout to use generic vector
1438 marking code. Fix some comments. Change type of 'clip_changed'
1439 to bitfield. Remove unused #ifndef old.
1440 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
1441 (GET_OVERLAYS_AT): Fix indentation.
1442 (for_each_per_buffer_object_at): New macro.
1443 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
1444 (Fbuffer_local_variables): Use it.
1445 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
1446 * alloc.c (allocate_buffer): Adjust to match new layout of
1447 struct buffer. Fix comment.
1448 (mark_overlay): New function.
1449 (mark_buffer): Use it. Use mark_vectorlike to mark normal
1450 Lisp area of struct buffer.
1451 (mark_object): Use it. Adjust marking of misc objects
1452 and related comments.
1454 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
1456 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
1457 wrapper that is not needed because the wrapped code is a no-op (zero
1458 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
1459 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
1461 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
1463 * alloc.c (mark_buffer): Simplify. Remove prototype.
1464 (mark_object): Add comment. Reorganize marking of vector-like
1465 objects. Use CHECK_LIVE for all vector-like objects except buffers
1466 and subroutines when GC_CHECK_MARKED_OBJECTS is defined. Avoid
1467 redundant calls to mark_vectorlike for bool vectors.
1469 2012-06-30 Glenn Morris <rgm@gnu.org>
1471 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
1473 * epaths.in (PATH_SITELOADSEARCH): New.
1474 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
1475 This is rather than relying on --enable-locallisppath elements
1476 having "site-lisp" in their names. (Bug#10208#25, 11658)
1478 2012-06-30 Eli Zaretskii <eliz@gnu.org>
1480 * w32proc.c (sys_select): Accept and ignore one more argument.
1482 * w32.c (emacs_gnutls_pull): Call select with one more argument.
1484 * sysselect.h [DOS_NT]: Don't include sys/select.h.
1485 (pselect) [!MS_DOS]: Redirect to sys_select.
1487 * sysdep.c: Don't include dos.h and dosfns.h.
1489 * process.c (sys_select):
1490 * msdos.c (sys_select): Accept one more argument and ignore it.
1492 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
1493 adapt data types and code to that.
1496 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
1497 which clashes with the gnulib function of the same name.
1499 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
1501 * font.c (font_style_to_value, font_style_symbolic)
1502 (font_prop_validate_style): Add type checks for values in
1505 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
1507 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
1510 2012-06-29 Eli Zaretskii <eliz@gnu.org>
1512 * xdisp.c (try_window_id): Undo last change.
1514 * w32.c (getwd): Adjust commentary about startup_dir.
1515 (init_environment): Always call sys_access, even in non-MSVC
1516 builds. Don't chdir to the directory of the Emacs executable.
1517 This undoes code from 1997 which was justified by the need to
1518 "avoid conflicts when removing and renaming directories". But its
1519 downside was that every relative file name was being interpreted
1520 relative to the directory of the Emacs executable, which can never
1521 be TRT. In particular, it broke sys_access when called with
1522 relative file names.
1523 (sys_access): Map GetLastError to errno.
1525 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
1527 * window.h (struct window): Change type of 'fringes_outside_margins'
1528 to bitfield. Fix comment. Adjust users accordingly.
1529 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
1531 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
1534 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
1536 * gnutls.c (emacs_gnutls_handshake):
1537 Add QUIT to make the loop interruptible.
1539 2012-06-29 Glenn Morris <rgm@gnu.org>
1541 * charset.c (init_charset): Make lack of etc/charsets fatal.
1543 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
1545 * editfns.c (region_limit): Fix type mismatch.
1547 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
1549 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
1550 undefined. Convert from xassert to eassert.
1551 * nsmenu.m: Convert from xassert to eassert.
1552 * nsterm.m: Likewise.
1554 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
1556 * editfns.c (region_limit): Clip to narrowing (bug#11770).
1558 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
1560 Avoid integer overflow on scroll-left and scroll-right.
1561 * window.c (HSCROLL_MAX): New macro.
1562 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
1563 overflow when requested scroll falls outside ptrdiff_t range.
1565 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
1567 * window.h (struct window): Change type of 'hscroll',
1568 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
1569 'last_modified' and 'last_overlay_modified' to EMACS_INT.
1570 Adjust users accordingly.
1571 * xdisp.c (try_cursor_movement): Replace type check with eassert.
1572 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
1573 from EMACS_INT to ptrdiff_t.
1574 (make_window): Omit redundant initialization.
1576 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
1578 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
1580 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
1582 * window.h (struct window): Change type of 'use_time' and
1583 'sequence_number' from Lisp_Object to int.
1584 * frame.c (make_frame): Adjust users accordingly.
1585 * print.c (print_object): Likewise.

1592 enabled with --enable-checking=[all,glyphs] configure option.
1593 Fix GLYPH_DEBUG usage assuming that it may be undefined,
1594 adjust comments accordingly.

1643 * alloc.c (allocate_string_data): Remove dead code.
1644 * xsettings.c (XSETTINGS_FONT_NAME): Move under HAVE_XFT to
1645 avoid GCC warning about unused macro.
1647 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
1649 * alloc.c (allocate_string): Omit intervals initialization.
1650 * alloc.c (make_uninit_multibyte_string): Initialize intervals
1651 as in make_pure_string and make_pure_c_string.
1653 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
1655 * alloc.c (allocate_string): Fix last change.
1657 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>

1682 2012-06-26 Eli Zaretskii <eliz@gnu.org>
1684 * s/ms-w32.h (strcasecmp, strncasecmp) [_MSC_VER]: Redirect to
1685 _stricmp and _strnicmp.
1686 (HAVE_STRCASECMP, HAVE_STRNCASECMP): Define to 1.

1703 * term.c (delete_tty): Remove redundant call to memset.
1705 2012-06-26 Dmitry Antipov <dmantipov@yandex.ru>
1707 * alloc.c: Remove build_string.
1708 * lisp.h: Define build_string as static inline. This provides
1709 a better opportunity to optimize away calls to strlen when the
1710 function is called with compile-time constant argument.
1711 * image.c (imagemagick_error): Convert to build_string.
1712 * w32proc.c (sys_spawnve): Likewise.
1713 * xterm.c (x_term_init): Likewise.
1715 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
1717 Use sprintf return value instead of invoking strlen on result.
1718 In the old days this wasn't portable, since some sprintf
1719 implementations returned char *. But they died out years ago and
1720 Emacs already assumes sprintf returns int.
1721 Similarly for float_to_string.
1722 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
1723 * ccl.c (ccl_driver):
1724 * character.c (string_escape_byte8):

1727 * print.c (print_object):
1728 * xdisp.c (message_dolog):
1729 * xfns.c (syms_of_xfns):
1730 Use sprintf or float_to_string result to avoid need to call strlen.
1731 * data.c (Fnumber_to_string):
1732 Use make_unibyte_string, since the string must be ASCII.
1733 * lisp.h, print.c (float_to_string): Now returns int length.
1734 * term.c (produce_glyphless_glyph):
1735 Use sprintf result rather than recomputing it.
1737 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
1738 * Makefile.in (ALL_CFLAGS):
1739 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
1740 * gmalloc.c, regex.c: Include <config.h> unconditionally.

1744 * dispextern.h (xstrcasecmp): Define to library function
1745 strcasecmp if available.
1746 * xfaces.c: Do not use xstrcasecmp if strcasecmp is available.
1748 2012-06-25 Andreas Schwab <schwab@linux-m68k.org>
1750 * keyboard.c (menu_bar_items, menu_bar_item, read_key_sequence):

1761 2012-06-25 Paul Eggert <eggert@cs.ucla.edu>
1763 * gtkutil.c (get_utf8_string): Remove redundant assignment.
1764 sprintf already null-terminates its output.
1766 * xfns.c (x_window): Remove redundant cast.
1768 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
1770 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
1771 `const char *' to `char *' to avoid compiler warning.
1773 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
1775 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
1776 instead of truncating it to 63 (admittedly a generous limit).
1778 * process.c: Fix spelling and caps in comments.
1780 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
1782 * emacs.c (setpgrp): Remove definition, unused.

1792 (SYSTIME_H): Add nt/inc/sys/time.h.
1794 * systime.h [WINDOWSNT]: Include sys/time.h.
1796 * s/ms-w32.h (struct timespec): Definition moved from
1797 nt/inc/sys/time.h. Suggested by Paul Eggert <eggert@cs.ucla.edu>.
1799 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>

1827 No need for separate decl merely because of _Noreturn.
1828 * sound.c (sound_warning, parse_sound):
1829 Remove unnecessary forward decls.
1831 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
1833 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
1834 * lisp.h (WAIT_READING_MAX): New macro.
1835 * dispnew.c (Fsleep_for, sit_for):
1836 * keyboard.c (kbd_buffer_get_event):
1837 * process.c (Faccept_process_output):
1838 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
1839 This improves on the previous patch, which introduced a bug
1840 when time_t is unsigned and as wide as intmax_t.
1841 See <http://bugs.gnu.org/9000#51>.
1843 2012-06-23 Eli Zaretskii <eliz@gnu.org>

1850 2012-06-23 Juanma Barranquero <lekktu@gmail.com>
1852 * makefile.w32-in: Update dependencies.
1854 * w32.c (ltime): Add return type and declare static.
1855 (w32_get_internal_run_time): Remove usused variable `time_100ns'.
1857 2012-06-23 Paul Eggert <eggert@cs.ucla.edu>
1859 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
1860 Privately reported by Herbert J. Skuhra.
1861 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
1863 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
1864 not make_lisp_timeval, when the argument is of type EMACS_TIME.
1866 2012-06-23 Eli Zaretskii <eliz@gnu.org>
1868 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
1869 last argument of make_unibyte_string.
1871 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
1872 language ID in the event parameters.
1874 * w32term.c (w32_read_socket): Put the new keyboard codepage into
1875 event.code, not the obscure "character set ID".
1877 2012-06-23 Chong Yidong <cyd@gnu.org>
1879 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.
1881 2012-06-23 Eli Zaretskii <eliz@gnu.org>
1883 Fix the MS-Windows build broken by 2012-06-22T21:17:42Z!eggert@cs.ucla.edu.
1884 * w32.c (fdutimens): New function.
1886 * w32proc.c (sys_select): Adapt to change in the EMACS_TIME type.
1888 * s/ms-w32.h (pselect): Redirect to sys_select.
1890 * sysselect.h [WINDOWSNT]: Don't include sys/select.h.
1892 * ralloc.c (r_alloc_inhibit_buffer_relocation): Fix stupid thinko
1893 in the logic of incrementing and decrementing the value of
1894 use_relocatable_buffers.

1898 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
1899 Privately reported by Herbert J. Skuhra.
1900 [__FreeBSD__]: Remove "*/" typo after "#include".
1901 (timeval_to_EMACS_TIME) [__FreeBSD__]: New static function.
1902 (TIMEVAL) [__FreeBSD__]: Now a static function rather than a macro.
1903 (TIMEVAL, system_process_attributes) [__FreeBSD__]:
1904 Don't assume EMACS_TIME and struct timeval are the same type.
1906 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
1908 Support higher-resolution time stamps (Bug#9000).
1909 The time stamps are only nanosecond-resolution at the C level,
1910 since that's the best that any real-world system supports now.
1911 But they are picosecond-resolution at the Lisp level, as that's
1912 easy, and leaves room for future OS improvements.
1914 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
1917 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
1918 Don't get current time unless it's needed.

1978 * nsterm.m (select_timeout, timeval_subtract): Remove.
1979 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,

2005 (Fprocess_attributes): Now generates ns-resolution time stamps.
2007 * sysdep.c: Include utimens.h. Don't include utime.h
2008 or worry about struct utimbuf; gnulib does that for us now.

2015 Now returns ns-resolution time stamp. All uses changed.
2016 Check for time stamp overflow.
2018 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
2019 provides a substitute now.
2021 * systime.h: Include timespec.h rather than sys/time.h and time.h,
2022 since it guarantees struct timespec.
2023 (EMACS_TIME): Now struct timespec, so that we can support
2024 ns-resolution time stamps.
2025 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
2026 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
2027 (EMACS_USECS): Remove.
2028 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
2029 so multiply the arg by 1000 before storing it.

2039 (make_timeval, make_lisp_time, decode_time_components): New decls.
2040 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
2041 that it mishandled time_t overflow. You can't compare by subtracting!
2042 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
2043 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.

2070 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
2071 (timeval_subtract): Remove; no longer needed.
2072 (XTflash, XTring_bell, x_wait_for_event):

2079 2012-06-22 Eli Zaretskii <eliz@gnu.org>
2081 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
2082 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
2083 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
2084 staticidx goes up to 1597 out of 1600 = 0x640.)
2086 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
2088 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
2089 Otherwise, the umask might be mistakenly 0 while handling input signals.

2122 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
2123 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
2124 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
2125 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.

2132 2012-06-18 Martin Rudalics <rudalics@gmx.at>
2134 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
2135 gets killed during executing of this function (Bug#11665).
2136 Try to always return Qt when the buffer has been actually killed.
2137 (Vkill_buffer_query_functions): In doc-string say that functions
2138 run by this hook should not change the current buffer.
2140 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
2142 Fix recently-introduced process.c problems found by static checking.

2163 This removes the need for CHECK.
2164 (CHECK): Remove. Its comments about always evaluating its
2165 argument were confusing, as 'eassert' typically does not evaluate
2168 * coding.c (produce_chars): Use ptrdiff_t, not int.
2170 * xterm.c (x_draw_underwave): Check for integer overflow.
2171 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

2502 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
2504 * doprnt.c (doprnt): Truncate multibyte char correctly.
2505 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
2506 would mishandle a string argument "Xc" if X was a multibyte
2507 character of length 2: it would truncate after X's first byte
2508 rather than including all of X.
2510 2012-06-06 Chong Yidong <cyd@gnu.org>
2512 * buffer.c (word_wrap): Doc fix.

2565 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
2567 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
2570 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
2572 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
2574 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
2576 For a 'struct window', replace some Lisp_Object fields to
2577 bitfields where appropriate, remove unused fields.
2578 * window.h (struct window): Remove unused 'last_mark_x' and
2579 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
2580 change it's type from Lisp_Object to bitfield.
2581 Change type of 'force_start', 'optional_new_start',
2582 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
2583 fields from Lisp_Object to bitfield. Adjust users accordingly.
2585 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
2587 Pacify gcc -Wdouble-precision when using Xaw.

2589 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
2590 Use 'float' consistently, rather than 'float' in most places
2591 and 'double' in a couple of places.
2593 2012-05-31 Eli Zaretskii <eliz@gnu.org>
2595 * xdisp.c (handle_stop): Detect whether we have overlay strings
2596 loaded by testing it->current.overlay_string_index to be
2597 non-negative, instead of checking whether n_overlay_strings is
2598 positive. (Bug#11587)
2600 2012-05-31 Chong Yidong <cyd@gnu.org>
2602 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
2604 * doc.c (Fsubstitute_command_keys): Doc fix.
2606 2012-05-31 Eli Zaretskii <eliz@gnu.org>
2608 * search.c (search_buffer): Remove calls to
2609 r_alloc_inhibit_buffer_relocation, as it is now called by
2610 maybe_unify_char, which was the cause of relocation of buffer text
2613 2012-05-31 Eli Zaretskii <eliz@gnu.org>
2615 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
2616 for the duration of call to load_charset, to avoid problems with
2617 callers of maybe_unify_char that access buffer text through C
2620 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
2621 decrement the inhibition flag, instead of just setting or
2624 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
2626 Remove obsolete '#define static' cruft.
2627 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
2628 This #undef was "temporary" in 2000; it is no longer needed
2629 now that '#define static' has gone away.
2630 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
2631 (gray_bitmap_bits): Remove; no longer needed.
2632 All uses replaced with definiens.
2633 * xterm.c: Include "bitmaps/gray.xbm".
2635 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
2637 Clean up __executable_start, monstartup when --enable-profiling.
2638 The following changes affect the code only when profiling.
2639 * dispnew.c (__executable_start): Rename from safe_bcopy.
2640 Define only on platforms that need it.
2641 * emacs.c: Include <sys/gmon.h> when profiling.
2642 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.

2644 (safe_bcopy): Remove decl; no longer has that name.
2645 (main): Coalesce #if into single bit of code, for simplicity.

2675 Do not create empty overlays with the evaporate property (Bug#9642).
2676 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
2677 Bug#9642, but explicitly check that the buffer the overlay would
2678 be moved to is live and rearrange lines to make sure that errors
2679 will not put the overlay in an inconsistent state.
2680 (Fdelete_overlay): Cosmetics.
2682 2012-05-28 Eli Zaretskii <eliz@gnu.org>
2684 * w32term.c (my_bring_window_to_top): New function.
2685 (x_raise_frame): Use handle returned by DeferWindowPos, which

2690 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
2691 by calling BringWindowToTop.

2696 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
2698 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
2699 This avoids undefined behavior that might cause the eassert
2700 to not catch an out-of-range value.
2702 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
2704 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

2718 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
2719 Only r_alloc_inhibit_buffer_relocation needed to be added;
2720 the others were already declared.
2722 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
2723 before checking whether it's out of range. Put the check inside
2725 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
2727 2012-05-27 Ken Brown <kbrown@cornell.edu>
2729 * callproc.c (Fcall_process): Restore a line that was accidentally
2730 commented out in the 2011-02-13 change (bug#11547).

2734 * lisp.h [REL_ALLOC]: Add prototypes for external functions
2735 defined on ralloc.c.
2737 * buffer.c [REL_ALLOC]: Remove prototypes of

2739 they are now on lisp.h.
2741 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
2743 * search.c (search_buffer): Use it to inhibit relocation of buffer
2744 text while re_search_2 is doing its job, because re_search_2 is
2745 passed C pointers to buffer text. (Bug#11519)
2747 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
2750 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator

2755 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
2758 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
2760 Fix coding-related core dumps with gcc -ftrapv.
2761 The code was computing A - B, where A and B are pointers, and B is
2762 random garbage. This can lead to core dumps on platforms that
2763 have special pointer registers, and it also leads to core dumps on
2764 x86-64 when compiled with gcc -ftrapv. The fix is to compute
2765 A - B only when B is initialized properly.
2766 * coding.c (coding_set_source, coding_set_destination): Return void.
2767 (coding_change_source, coding_change_destinations): New functions,
2768 with the old behaviors of coding_set_source and coding_set_destination.
2769 All callers that need an offset changed to use these new functions.

2773 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
2775 2012-05-26 Eli Zaretskii <eliz@gnu.org>

2778 * xdisp.c (draw_row_with_mouse_face):
2779 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
2781 * w32console.c: Include window.h.
2782 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
2784 (initialize_w32_display): Initialize mouse-highlight data.
2786 * w32inevt.c: Include termchar.h and window.h.
2787 (do_mouse_event): Support mouse-autoselect-window. When the mouse
2788 moves, call note_mouse_highlight. If help_echo changed, call
2789 gen_help_event to produce help-echo message in the echo area.
2790 Call clear_mouse_face if mouse_face_hidden is set in the mouse
2793 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
2795 * lread.c (read1): Simplify slightly to avoid an overflow warning
2796 with GCC 4.7.0 on x86-64.
2798 2012-05-26 Eli Zaretskii <eliz@gnu.org>
2800 * bidi.c (bidi_mirror_char): Revert last change: an int is
2801 definitely wide enough here.

2813 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
2815 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2816 (allocate_pseudovector):
2817 Use int, not EMACS_INT, where int is wide enough.
2818 (inhibit_garbage_collection, Fgarbage_collect):
2819 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
2820 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
2821 int might not be wide enough.
2822 (bidi_cache_search, bidi_cache_find, bidi_init_it)

2830 (advance_to_char_boundary, Fbuffer_swap_text)
2831 (Fset_buffer_multibyte, overlays_at, overlays_in)

2833 (overlay_strings, recenter_overlay_lists)
2834 (adjust_overlays_for_insert, adjust_overlays_for_delete)
2835 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
2836 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
2837 (Foverlay_recenter, last_overlay_modification_hooks_used)
2838 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
2839 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2840 (validate_region): Omit unnecessary test for b <= e,
2841 since that's guaranteed by the previous test.

2843 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
2844 (report_overlay_modification):

2846 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
2847 Omit pointer cast, which isn't needed anyway, and doesn't work
2848 after the EMACS_INT -> ptrdiff_t change.
2849 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.

2855 not int, to avoid needless 32-bit limit on 64-bit hosts.
2856 (exec_byte_code): Use tighter memory-full test, one that checks
2857 for alloca overflow. Don't compute the address of the object just
2858 before an array, as that's not portable. Use EMACS_INT, not
2859 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
2860 * callint.c (Fcall_interactively):
2861 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

2872 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
2873 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2874 (casify_object): Avoid integer overflow when overallocating buffer.
2875 * casetab.c (set_identity, shuffle): Prefer int to unsigned when

2878 * category.h (CATEGORYP): Don't assume arg is nonnegative.
2879 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
2880 integers are now checked earlier. All uses replaced with XINT.
2882 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2883 For CCL_MapSingle, check that content and value are in int range.
2884 (ccl_driver, Fregister_code_conversion_map):
2885 Check that Vcode_version_map_vector is a vector.
2886 (resolve_symbol_ccl_program): Check that vector header is in range.
2887 Always copy the vector, so that we can check its contents reliably
2888 now rather than having to recheck each instruction as it's being
2889 executed. Check that vector words fit in 'int'.
2890 (ccl_get_compiled_code, Fregister_ccl_program)
2891 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
2892 program indexes, to avoid needless 32-bit limit on 64-bit hosts.

2894 contents are in range.
2895 (Fccl_execute_on_string): Check that status is in range.
2896 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
2897 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
2898 Accept and return EMACS_INT, not int, because callers can pass values

2905 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

2918 Don't rely on undefined behavior with signed left shift overflow.
2919 Don't assume unsigned int fits into fixnum, or that fixnum fits
2920 into unsigned int. Don't require max_code to be a valid fixnum;
2921 that's not true for gb10830 4-byte on a 32-bit host. Allow
2922 invalid_code to be a cons, for the same reason. Require code_offset
2923 to be a character. Avoid int overflow if max_char is close
2925 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
2926 this is intended anyway and avoids some undefined behavior.
2927 (load_charset_map): Pass unsigned, not int, as 2nd arg of
2928 INDEX_TO_CODE_POINT, as that's what it expects.
2929 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
2930 * charset.h (DECODE_CHAR): Return int, not unsigned;
2931 this is what was intended anyway, and it avoids undefined behavior.
2932 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
2933 integer-overflow issues.
2934 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
2935 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
2936 where the argument is EMACS_INT, and this behavior is not intended.
2937 * chartab.c (Fmake_char_table, Fset_char_table_range)
2938 (uniprop_get_decoder, uniprop_get_encoder):
2939 Don't assume fixnum fits in int.
2940 * cmds.c (move_point): New function, that does the gist of
2941 Fforward_char and Fbackward_char, but does so while checking
2942 for integer overflow more accurately.
2943 (Fforward_char, Fbackward_char): Use it.
2944 (Fforward_line, Fend_of_line, internal_self_insert)
2945 (internal_self_insert):
2946 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

3549 (handle_tool_bar_click):
3550 Use int, not unsigned, since we prefer signed and the signedness
3551 doesn't matter here.
3552 (get_next_display_element, next_element_from_display_vector):
3553 Use int, not EMACS_INT, when int is wide enough.
3554 (start_hourglass): Use duration_to_sec_usec to do proper
3555 overflow checking on durations.
3556 * xfaces.c (Fbitmap_spec_p):
3557 Check that fixnums are in proper range for system types.
3558 (compare_fonts_by_sort_order):
3559 Avoid mishandling comparisons due to subtraction overflow.

3564 Use SAFE_ALLOCA_LISP, not alloca.
3565 (merge_face_heights): Remove unnecessary cast to EMACS_INT.

3568 (face_at_string_position):
3569 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3570 (merge_faces): Use int, not EMACS_INT, where int is wide enough.
3571 * xfns.c (x_set_menu_bar_lines, x_set_tool_bar_lines, x_icon_verify)
3573 Check that fixnums are in proper range for system types.
3574 (Fx_create_frame, x_create_tip_frame, Fx_show_tip)
3575 (Fx_hide_tip, Fx_file_dialog, Fx_select_font):

3577 (Fx_change_window_property): Don't assume fixnums fit in int.
3578 * xfont.c (xfont_chars_supported):
3579 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

3583 * xml.c (parse_region):
3584 * xrdb.c (magic_file_p):
3585 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

3587 (x_get_local_selection, x_reply_selection_request)
3588 (x_handle_selection_request, wait_for_property_change):
3589 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3590 (selection_data_to_lisp_data): Use short, not EMACS_INT, where
3591 short is wide enough.
3592 (x_send_client_event): Don't assume fixnum fits in int.
3593 * xterm.c (x_x_to_emacs_modifiers):
3594 Don't assume EMACS_INT overflows nicely into int.
3595 (x_emacs_to_x_modifiers): Use EMACS_INT, not int, because values
3597 (handle_one_xevent): NATNUMP can eval its arg twice.
3598 (x_connection_closed):
3599 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3600 * xterm.h: Adjust decls to match defn changes elsewhere.
3601 (struct scroll_bar): Use struct vectorlike_header
3602 rather than rolling our own approximation.
3603 (SCROLL_BAR_VEC_SIZE): Remove; not used.
3605 2012-05-25 Glenn Morris <rgm@gnu.org>
3607 * lisp.mk (lisp): Update for more files being compiled now.
3609 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
3611 * lread.c: Remove `read_pure' which makes no difference.
3612 (read_pure): Remove var.
3613 (unreadpure): Remove function.
3614 (readevalloop): Don't call read_list with -1 flag.
3615 (read1, read_vector): Don't test read_pure any more.
3616 (read_list): Simplify.
3618 * fileio.c, character.h: Minor style tweaks.
3620 2012-05-24 Dmitry Antipov <dmantipov@yandex.ru>
3622 * window.h (clip_changed): Remove useless declaration.
3624 2012-05-22 Juanma Barranquero <lekktu@gmail.com>

3627 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
3629 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
3632 This directory predates autoconf and is no longer needed nowadays.
3633 Move its few remaining bits of functionality to where they're needed.
3634 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:
3635 * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:

3639 * lisp.h (USE_LSB_TAG):
3640 * mem-limits.h (EXCEEDS_LISP_PTR):
3641 Use VAL_MAX, not VALBITS, in #if.
3642 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
3643 (EMACS_UINT): Define unconditionally now.
3644 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
3645 (BITS_PER_EMACS_INT): New constants, replacing
3646 what used to be in config.h, but not useful in #if.
3647 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
3648 define them any more.
3649 (VAL_MAX): New macro.
3651 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
3652 BITS_PER_EMACS_INT, in #if.
3653 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
3654 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
3655 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
3656 * s/ms-w32.h (DATA_START):
3657 Move here from removed file m/intel386.h.
3658 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
3659 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
3661 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
3663 Assume C89 or later.
3664 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.

3671 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
3672 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
3673 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
3674 * xterm.c (input_signal_count): Assume volatile works.
3676 2012-05-21 Ken Brown <kbrown@cornell.edu>
3678 * xgselect.c (xg_select): Fix first argument in call to 'select'
3681 2012-05-20 Ken Brown <kbrown@cornell.edu>
3683 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
3684 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
3686 2012-05-19 Ken Brown <kbrown@cornell.edu>
3688 * xfns.c (x_in_use): Remove `static' qualifier.
3689 * xterm.h (x_in_use): Declare.
3690 * xgselect.c: Include xterm.h.
3691 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
3692 and `display_arg' (bug#9754).
3694 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
3696 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
3698 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
3699 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
3701 2012-05-18 Eli Zaretskii <eliz@gnu.org>
3703 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
3705 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
3706 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
3708 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
3709 reference to image_cache->refcount.
3710 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
3712 2012-05-17 Juri Linkov <juri@jurta.org>
3714 * search.c (Fword_search_regexp, Fword_search_backward)
3715 (Fword_search_forward, Fword_search_backward_lax)
3716 (Fword_search_forward_lax): Move functions to isearch.el
3717 (bug#10145, bug#11381).
3719 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
3721 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
3723 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
3725 * lread.c (init_obarray): Declare Qt and Qnil as special.
3727 2012-05-14 Glenn Morris <rgm@gnu.org>
3729 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
3730 Put "libexec" before "bin", for the sake of init_callproc_1.
3732 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
3734 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
3736 * unexaix.c: Port to more-recent AIX compilers.
3737 (report_error, report_error_1, make_hdr, copy_sym)
3738 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
3739 Make arguments const char *, not char *, to avoid violations of C
3740 standard and to fix some AIX warnings reported by Gilles Pion.
3742 2012-05-14 Eli Zaretskii <eliz@gnu.org>
3744 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
3745 already have overlays loaded.
3746 (handle_single_display_spec): Before returning without displaying
3747 fringe bitmap, synchronize the bidi iterator with the main display
3748 iterator, by calling iterate_out_of_display_property.
3749 (iterate_out_of_display_property): Detect buffer iteration by
3750 testing that it->string is a Lisp string.
3751 (get_next_display_element): When the current object is exhausted,
3752 and there's something on it->stack, call set_iterator_to_next to
3753 proceed with what's on the stack, instead of returning zero.
3754 (set_iterator_to_next): If called at the end of a Lisp string,
3755 proceed to consider_string_end without incrementing string
3756 position. Don't increment display vector index past the end of
3757 the display vector. (Bug#11417)
3758 (pos_visible_p): Don't report a position visible when move_it_to
3759 stopped at the last line of window, which happens to be scanned
3760 backwards by the bidi iteration. (Bug#11464)
3762 2012-05-14 Eli Zaretskii <eliz@gnu.org>
3764 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
3765 and right-margin display specs even if the spec is invalid or we
3766 are on a TTY, and thus unable to display on the fringes.
3767 That's because the text with the property will not be displayed anyway,
3768 so we need to signal to the caller that this is a "replacing"
3769 display spec. This fixes display when the spec is invalid or we
3772 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
3774 * unexaix.c (make_hdr): Fix typo in prototype.
3775 This bug broke the build on AIX. Problem reported by Gilles Pion.
3777 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
3779 * keyboard.c (kbd_buffer_get_event): Read special events also in
3780 batch mode. (Bug#11415)
3782 2012-05-12 Glenn Morris <rgm@gnu.org>
3784 * ns.mk: Update for ns_appbindir no longer having trailing "/".
3786 2012-05-12 Eli Zaretskii <eliz@gnu.org>
3788 * lisp.mk (lisp): Add newcomment.elc.
3790 2012-05-12 Glenn Morris <rgm@gnu.org>
3792 * Makefile.in (MKDIR_P): New, set by configure.
3793 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
3795 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
3797 Remove unused function hourglass_started.
3798 * dispextern.h (hourglass_started):
3799 * w32fns.c (hourglass_started):
3800 * xdisp.c (hourglass_started): Remove.
3802 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
3804 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
3805 Update dependencies.
3807 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
3809 * xgselect.c (xg_select): Put maxfds+1 into a var.
3810 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
3812 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
3814 2012-05-10 Dave Abrahams <dave@boostpro.com>
3816 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
3817 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
3819 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
3821 * dbusbind.c (xd_registered_buses): New internal Lisp object.
3822 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
3823 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
3824 Initialize xd_registered_buses.
3826 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
3828 Untag more efficiently if USE_LSB_TAG.
3829 This is based on a proposal by YAMAMOTO Mitsuharu in
3830 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
3831 For an admittedly artificial (nth 8000 longlist) benchmark on
3832 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
3833 Emacs's overall text size by 1%.
3834 * lisp.h (XUNTAG): New macro.
3835 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
3836 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
3837 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
3838 * eval.c (Fautoload):
3839 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
3840 * frame.h (XFRAME): Use XUNTAG.
3842 Port recent dbusbind.c changes to 32-bit --with-wide-int.
3843 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
3844 Remove unportable assumptions about print widths of types like
3846 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
3847 intptr_t when converting between pointer and integer, to avoid GCC
3848 warnings about wrong width.
3850 2012-05-09 Eli Zaretskii <eliz@gnu.org>
3852 * w32proc.c (new_child): Force Windows to reserve only 64KB of
3853 stack for each reader_thread, instead of defaulting to 8MB
3854 determined by the linker. This avoids failures in creating
3855 subprocesses on Windows 7, see the discussion in this thread:
3856 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
3858 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
3860 Fix up display of the *Minibuf-0* buffer in the mini window.
3861 * keyboard.c (read_char): Don't clear the echo area if there's no
3863 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
3864 contents of *Minibuf-0*) if there's no message displayed in its stead.
3866 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
3868 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
3871 2012-05-06 Chong Yidong <cyd@gnu.org>
3873 * lisp.mk (lisp): Update.
3875 2012-05-05 Jim Meyering <meyering@redhat.com>
3877 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
3879 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
3881 * data.c (PUT_ERROR): New macro.
3882 (syms_of_data): Use it. Add new error type `user-error'.
3883 * undo.c (user_error): New function.
3884 (Fprimitive_undo): Use it.
3885 * print.c (print_error_message): Adjust print style for `user-error'.
3886 * keyboard.c (user_error): New function.
3887 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
3889 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
3891 Do not limit current-time-string to years 1000..9999.
3892 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
3893 (Fcurrent_time_string): Support any year that is supported by the
3894 underlying localtime representation. Don't use asctime, as it
3895 has undefined behavior for years outside the range -999..9999.
3897 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
3899 Fix race conditions involving setenv, gmtime, localtime, asctime.
3900 Without this fix, interrupts could mess up code that uses these
3901 nonreentrant functions, since setting TZ invalidates existing
3902 tm_zone or tzname values, and since most of these functions return
3903 pointers to static storage.
3904 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
3905 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
3906 Grow the critical sections to include not just invoking
3907 localtime/gmtime, but also accessing these functions' results
3908 including their tm_zone values if any, and any related TZ setting.
3909 (format_time_string): Last arg is now struct tm *, not struct tm **,
3910 so that the struct tm is saved in the critical section.
3911 All callers changed. Simplify allocation of initial buffer, partly
3912 motivated by the fact that memory allocation needs to be outside
3913 the critical section.
3915 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
3917 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
3918 with RESET_INTERVAL.
3920 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
3921 Remove duplicated buffer name initialization.
3923 2012-05-02 Jim Meyering <jim@meyering.net>
3925 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
3927 * xfns.c (x_window): Use xstrdup (Bug#11375).
3929 2012-05-02 Eli Zaretskii <eliz@gnu.org>
3931 * xdisp.c (pos_visible_p): If already at a newline from the
3932 display string before the 'while' loop, don't walk back the glyphs
3933 from it3.glyph_row. Solves assertion violation when the display
3934 string begins with a newline (egg.el). (Bug#11367)
3936 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
3938 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
3941 2012-05-01 Glenn Morris <rgm@gnu.org>
3943 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
3944 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
3945 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
3946 All were removed before 23.1.
3948 * dispnew.c: Remove HAVE_LIBNCURSES test;
3949 it is always true on relevant platforms.
3951 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
3952 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
3954 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
3956 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
3958 * .gdbinit (xpr): Remove checks for no longer existing misc types.
3959 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
3962 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
3964 Do not avoid creating empty evaporating overlays (Bug#9642).
3965 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
3966 That is, do not delete an evaporating overlay if it becomes
3967 empty after its bounds are adjusted to fit within its buffer.
3968 This fix caused other problems, and I'm reverting it until we get
3969 to the bottom of them.
3971 2012-04-27 Chong Yidong <cyd@gnu.org>
3973 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
3975 2012-04-27 Eli Zaretskii <eliz@gnu.org>
3977 * xdisp.c (pos_visible_p): If the window start position is beyond
3978 ZV, start the display from buffer beginning. Prevents assertion
3979 violation in init_iterator when the minibuffer window is scrolled
3982 * window.c (window_scroll_pixel_based): Likewise.
3984 2012-04-27 Chong Yidong <cyd@gnu.org>
3986 * keymap.c (where_is_internal): Doc fix (Bug#10872).
3988 2012-04-27 Glenn Morris <rgm@gnu.org>
3990 * fileio.c (Fcopy_file, Fset_file_selinux_context):
3991 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
3993 2012-04-27 Eli Zaretskii <eliz@gnu.org>
3995 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):

4030 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
4032 Do not create empty overlays with the evaporate property (Bug#9642).
4033 * buffer.c (Fmove_overlay): Delete an evaporating overlay
4034 if it becomes empty after its bounds are adjusted to fit within
4035 its buffer. Without this fix, in a nonempty buffer (let ((o
4036 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
4037 yields an empty overlay that has the evaporate property, which is
4038 not supposed to happen.

4142 since the two debugging options are incompatible.
4143 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
4145 (mem_init, mem_insert, mem_insert_fixup):
4146 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

4178 (print_object): Check for cycles even when print-circle is nil and
4179 print-gensym is t, but only check print_depth if print-circle is nil.
4181 2012-04-20 Chong Yidong <cyd@gnu.org>
4183 * process.c (wait_reading_process_output): If EIO occurs on a pty,

4239 New extern decls, to avoid calling undeclared functions.
4240 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
4241 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
4242 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.

4244 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
4245 Remove one incorrect comment and fix another.

4259 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
4260 Remove decls. This fixes an "It stinks!".
4262 * alloc.c (which_symbols): Fix alignment issue / type clash.
4264 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
4266 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

4283 Remove definition of GC_MARK_STACK, since the default now works.
4284 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
4285 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
4286 no longer the default.
4287 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
4289 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

4312 2012-04-11 Daniel Colascione <dancol@dancol.org>
4314 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
4315 against is gone. It's better to use vfork now so that when Cygwin
4316 gains a new, working vfork, we use it automatically (bug#10398).
4318 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

4373 2012-04-09 Eli Zaretskii <eliz@gnu.org>
4375 * xdisp.c (set_cursor_from_row): If the display string appears in
4376 the buffer at position that is closer to point than the position
4377 after the display string, display the cursor on the first glyph of
4378 the display string. Fixes cursor display when a 'display' text
4379 property immediately follows invisible text. (Bug#11094)
4381 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
4383 composite.c: use 'double' consistently
4384 * composite.c (get_composition_id): Use 'double' consistently
4385 instead of converting 'float' to 'double' and vice versa; this is
4386 easier to understand and avoids a GCC warning.
4388 2012-04-09 Glenn Morris <rgm@gnu.org>
4390 * Makefile.in: Generate leim-list with bootstrap-emacs, in
4391 preparation for dumping it with emacs. (Bug#4789)

4436 (init_libxml2_functions, libxml2_loaded_p): New functions.
4437 (parse_region): Call fn_xmlCheckVersion instead of using the macro
4438 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
4439 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
4440 Calls xmlCleanupParser only if libxml2 was loaded (or statically
4442 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
4443 Call init_libxml2_functions before calling libxml2 functions.
4444 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
4446 * emacs.c: Don't include libxml/parser.h.
4447 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
4448 xmlCleanupParser directly.
4450 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
4452 2012-04-07 Eli Zaretskii <eliz@gnu.org>
4454 * indent.c (Fvertical_motion): If there is a display string at
4455 point, use it.vpos to compute how many lines to backtrack after
4456 move_it_to point. (Bug#11133)
4458 2012-04-06 Eli Zaretskii <eliz@gnu.org>
4460 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
4461 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
4462 about subtle differences between FETCH_CHAR* and STRING_CHAR*
4463 macros related to unification of CJK characters. For the details,
4464 see the discussion following the message here:
4465 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
4467 2012-04-04 Chong Yidong <cyd@gnu.org>
4469 * keyboard.c (Vdelayed_warnings_list): Doc fix.
4471 2012-04-01 Eli Zaretskii <eliz@gnu.org>
4473 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
4474 instead of alloca. (Bug#11138)
4476 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
4478 * w32menu.c (is_simple_dialog): Properly check lisp types.
4481 2012-03-31 Eli Zaretskii <eliz@gnu.org>
4483 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
4484 position we get to after a call to move_it_to fails the
4485 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
4486 only if we wind up in a string from display property. (Bug#11063)
4488 * window.c (Fdelete_other_windows_internal): Invalidate the row
4489 and column information about mouse highlight, so that redisplay
4490 restores it after reallocating the glyph matrices. (Bug#7464)
4492 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
4493 string comes from a `display' text property, use the buffer
4494 position of that property as if we actually saw that position in
4496 (move_it_by_lines): Remove the assertion that
4497 "it->current_x == 0 && it->hpos == 0" which can be legitimately
4498 violated when there's a before-string at the beginning of a line.
4501 2012-03-30 Eli Zaretskii <eliz@gnu.org>
4503 * xdisp.c (append_space_for_newline): If the default face was
4504 remapped, use the remapped face for the appended newline.
4505 (extend_face_to_end_of_line): Use the remapped default face for
4506 extending the face to the end of the line.
4507 (display_line): Call extend_face_to_end_of_line when the default
4508 face was remapped. (Bug#11068)
4510 2012-03-29 Eli Zaretskii <eliz@gnu.org>
4512 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
4514 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
4516 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
4518 2012-03-27 Glenn Morris <rgm@gnu.org>
4520 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
4523 2012-03-26 Kenichi Handa <handa@m17n.org>
4525 * dispextern.h (struct glyph): Fix previous change. Change the
4526 bit length of glyphless.ch to 25 (Bug#11082).
4528 2012-03-26 Chong Yidong <cyd@gnu.org>
4530 * keyboard.c (Vselection_inhibit_update_commands): New variable.
4531 (command_loop_1): Use it; inhibit selection update for
4532 handle-select-window too (Bug#8996).
4534 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
4536 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
4538 2012-03-25 Kenichi Handa <handa@m17n.org>
4540 * dispextern.h (struct glyph): Change the bit length of
4541 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
4543 2012-03-24 Eli Zaretskii <eliz@gnu.org>
4545 * s/ms-w32.h (tzname): Include time.h before redirecting to
4546 _tzname. Fixes the MSVC build. (Bug#9960)
4548 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
4550 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
4553 * xterm.c (XTread_socket): Only modify handling_signal if
4554 !SYNC_INPUT. (Bug#11080)
4556 2012-03-23 Eli Zaretskii <eliz@gnu.org>
4558 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
4559 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
4560 when fetching a multibyte character consumes more bytes than
4561 CHAR_BYTES returns, due to unification of CJK characters in
4562 string_char. (Bug#11073)
4564 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
4566 * process.c (wait_reading_process_output): Handle pty disconnect
4567 by refraining from sending oneself a SIGCHLD (bug#10933).
4569 2012-03-22 Chong Yidong <cyd@gnu.org>
4571 * dispextern.h (struct it): New member string_from_prefix_prop_p.
4573 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
4574 Mark string as coming from a prefix property.
4575 (handle_face_prop): Use default face for prefix strings (Bug#4281).
4576 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
4578 2012-03-21 Chong Yidong <cyd@gnu.org>
4580 * xfaces.c (Vface_remapping_alist): Doc fix.
4582 2012-03-20 Eli Zaretskii <eliz@gnu.org>
4584 * w32proc.c (Fw32_set_console_codepage)
4585 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
4588 2012-03-20 Chong Yidong <cyd@gnu.org>
4590 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
4591 to reflect default non-nil value of redisplay-dont-pause.
4593 2012-03-19 Kenichi Handa <handa@m17n.org>
4595 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
4596 it fit in a valid range (Bug#11003).
4598 2012-03-18 Eli Zaretskii <eliz@gnu.org>
4600 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
4601 that is not from display property, accept the row as a "cursor
4602 row" if one of the string's character has a non-nil `cursor'
4603 property. Fixes cursor positioning when there are newlines in
4604 overlay strings, e.g. in icomplete.el. (Bug#11035)
4606 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
4608 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
4610 2012-03-12 Chong Yidong <cyd@gnu.org>
4612 * eval.c (inhibit_lisp_code): Rename from
4613 inhibit_window_configuration_change_hook; move from window.c.
4615 * xfns.c (unwind_create_frame_1, Fx_create_frame):
4616 * window.c (run_window_configuration_change_hook)
4617 (syms_of_window): Callers changed.
4619 2012-03-11 Chong Yidong <cyd@gnu.org>

4628 is visible (Bug#10955).
4630 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
4632 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
4634 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
4636 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
4637 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
4640 2012-03-03 Glenn Morris <rgm@gnu.org>
4642 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
4644 2012-03-02 Eli Zaretskii <eliz@gnu.org>
4646 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
4647 position past the first glyph_row that ends at ZV. (Bug#10902)
4648 (redisplay_window, next_element_from_string): Fix typos in
4650 (redisplay_window): Pass to move_it_vertically the margin in
4651 pixels, not in screen lines.
4653 2012-03-02 Glenn Morris <rgm@gnu.org>
4655 * buffer.c (buffer-list-update-hook): Doc fix.
4657 2012-02-29 Eli Zaretskii <eliz@gnu.org>
4659 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
4660 push_it before setting up the iterator for the first overlay
4661 string, even if we have an empty string loaded.
4662 (next_overlay_string): If there's an empty string on the iterator
4663 stack, pop the stack. (Bug#10903)
4665 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
4667 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
4668 Suggested by Stefan Monnier in
4669 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
4670 * alloc.c (widen_to_Lisp_Object): New static function.
4671 (mark_memory): Also mark Lisp_Objects by fetching pointer words
4672 and widening them to Lisp_Objects. This would work even if
4673 USE_LSB_TAG is defined and wide integers are used, which might
4674 happen in a future version of Emacs.
4676 2012-02-25 Chong Yidong <cyd@gnu.org>
4678 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
4681 * xselect.c (Fx_selection_exists_p): Doc fix.
4682 (x_clipboard_manager_save_all): Print an informative message
4683 before saving to clipboard manager.
4685 2012-02-24 Chong Yidong <cyd@gnu.org>
4687 * keyboard.c (process_special_events): Handle all X selection
4688 requests in kbd_buffer, not just the next one (Bug#8869).
4690 2012-02-23 Chong Yidong <cyd@gnu.org>
4692 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
4693 call when setting menu-bar-lines and tool-bar-lines parameters.
4694 (unwind_create_frame_1): New helper function.
4696 * window.c (inhibit_window_configuration_change_hook): New var.
4697 (run_window_configuration_change_hook): Obey it.
4698 (syms_of_window): Initialize it.
4700 2012-02-22 Chong Yidong <cyd@gnu.org>
4702 * xterm.c (x_draw_image_relief): Add missing type check for
4703 Vtool_bar_button_margin (Bug#10743).
4705 2012-02-21 Chong Yidong <cyd@gnu.org>
4707 * fileio.c (Vfile_name_handler_alist): Doc fix.
4709 * buffer.c (Fget_file_buffer): Protect against invalid file
4710 handler return value.
4712 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
4714 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
4715 when computing $valmask.
4717 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
4718 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
4719 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
4720 It's useless in that case, and it can cause problems on hosts
4721 that allocate halves of EMACS_INT values separately.
4722 Reported by Dan Horák. Diagnosed by Andreas Schwab in
4723 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
4724 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
4725 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
4726 it avoids undefined behavior on hosts where shifting right by more
4727 than the word width has undefined behavior.
4729 2012-02-19 Chong Yidong <cyd@gnu.org>
4731 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
4732 (Funhandled_file_name_directory, Ffile_name_as_directory)
4733 (Fdirectory_file_name, Fexpand_file_name)
4734 (Fsubstitute_in_file_name): Protect against invalid file handler
4735 return values (Bug#10845).
4737 2012-02-18 Eli Zaretskii <eliz@gnu.org>
4739 * .gdbinit (pitx): Fix incorrect references to fields of the
4742 2012-02-17 Chong Yidong <cyd@gnu.org>
4744 * syntax.c (Fscan_lists): Doc fix (Bug#10833).
4746 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
4748 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
4749 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
4751 2012-02-15 Chong Yidong <cyd@gnu.org>
4753 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
4754 marked as special. Also, starting docstrings with * is obsolete.
4756 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
4758 * gnutls.c (emacs_gnutls_write): Fix last change.
4760 2012-02-13 Lars Ingebrigtsen <larsi@gnus.org>

4765 2012-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
4767 * keymap.c (Fsingle_key_description): Handle char ranges.
4769 2012-02-12 Chong Yidong <cyd@gnu.org>
4771 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
4772 as that creates a dangerous corner case.
4774 * window.c (Fdelete_window_internal): Invalidate the mouse
4775 highlight (Bug#9904).
4777 2012-02-12 Glenn Morris <rgm@gnu.org>
4779 * xselect.c (Fx_own_selection_internal)
4780 (Fx_get_selection_internal, Fx_disown_selection_internal)
4781 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
4782 * nsselect.m (Fx_own_selection_internal)
4783 (Fx_disown_selection_internal, Fx_selection_exists_p)
4784 (Fx_selection_owner_p, Fx_get_selection_internal):
4785 Sync docs and argument specs with the xselect.c versions.
4787 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
4789 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
4791 2012-02-11 Eli Zaretskii <eliz@gnu.org>
4793 * w32select.c (Fx_selection_exists_p): Sync doc string and
4794 argument list with xselect.c. (Bug#10783)
4796 * w16select.c (Fx_selection_exists_p): Sync doc string and
4797 argument list with xselect.c. (Bug#10783)

4807 2012-02-07 Chong Yidong <cyd@gnu.org>
4809 * buffer.c (Fbuffer_local_variables)
4810 (buffer_lisp_local_variables): Handle unbound vars correctly;
4811 don't let Qunbound leak into Lisp.
4813 2012-02-07 Glenn Morris <rgm@gnu.org>
4815 * image.c (Fimagemagick_types): Doc fix.
4817 * image.c (imagemagick-render-type): Change it from a lisp object
4818 to an integer. Move the doc here from the lisp manual.

4821 2012-02-06 Chong Yidong <cyd@gnu.org>
4823 * doc.c (store_function_docstring): Avoid applying docstring of
4824 alias to base function (Bug#2603).
4826 2012-02-04 Andreas Schwab <schwab@linux-m68k.org>
4828 * .gdbinit (pp1, pv1): Remove redundant defines.
4831 2012-02-04 Chong Yidong <cyd@gnu.org>
4833 * nsterm.m: Declare a global (Bug#10694).
4835 2012-02-04 Eli Zaretskii <eliz@gnu.org>
4837 * w32.c (get_emacs_configuration_options):
4838 Include --enable-checking, if specified, in the return value.
4840 2012-02-04 Martin Rudalics <rudalics@gmx.at>
4842 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
4843 after rounding frame sizes. (Bug#9723)

4847 * keyboard.c (adjust_point_for_property): Don't position point
4848 before BEGV. (Bug#10696)
4850 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
4852 Handle overflow when computing char display width (Bug#9496).
4853 * character.c (char_width): Return EMACS_INT, not int.
4854 (char_width, c_string_width): Check for overflow when
4855 computing the width; this is possible now that individual
4856 characters can have unbounded width. Problem introduced
4857 by merge from Emacs 23 on 2012-01-19.
4859 2012-02-02 Michael Albinus <michael.albinus@gmx.de>
4861 * dbusbind.c (Fdbus_register_method): Mention the return value
4862 :ignore in the docstring.
4864 2012-02-02 Glenn Morris <rgm@gnu.org>
4866 * callproc.c (Fcall_process, Fcall_process_region): Doc fix.

4874 2012-02-02 Kenichi Handa <handa@m17n.org>
4876 (x_produce_glyphs): Cancel previous change. If cmp->glyph_len is
4877 0, do not call append_composite_glyph.
4879 2012-02-02 Kenichi Handa <handa@m17n.org>
4881 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
4883 (x_produce_glyphs): If the component of a composition is a null
4884 string, set it->pixel_width to 1 to avoid zero-width glyph.
4886 2012-02-01 Eli Zaretskii <eliz@gnu.org>
4888 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
4889 first 2 arguments are identical. This makes inserting large
4890 output from a subprocess an order of magnitude faster on
4891 MS-Windows, where all sbrk'ed memory is always contiguous.
4893 2012-01-31 Glenn Morris <rgm@gnu.org>
4895 * nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:

4931 2012-01-21 Chong Yidong <cyd@gnu.org>
4933 * floatfns.c (Fcopysign): Make the second argument non-optional,
4934 since nil is not allowed anyway.
4936 2012-01-21 Andreas Schwab <schwab@linux-m68k.org>
4938 * process.c (read_process_output): Use p instead of XPROCESS (proc).
4939 (send_process): Likewise.
4941 2012-01-19 Martin Rudalics <rudalics@gmx.at>
4943 * window.c (save_window_save, Fcurrent_window_configuration)
4944 (Vwindow_persistent_parameters): Do not use Qstate.
4945 Rewrite doc-strings.

5510 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
5511 is set, removing the need for VIRT_ADDRESS_VARIES.
5512 (PURE_P): Use a more-efficient implementation that needs just one
5513 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
5514 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
5515 to 4 (xorl, subq, cmpq, setbe).
5516 * alloc.c (pure): Always extern now, since that's the
5517 VIRT_ADDR_VARIES behavior.
5518 (PURE_POINTER_P): Use a single comparison, not two, for
5519 consistency with the new puresize.h.
5520 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.

5528 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
5529 behave as if the cursor position were at the window margin.
5531 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
5532 and the cursor position is out of bounds, behave as if the cursor
5533 position were at the window margin. (Bug#10075)
5535 2011-11-18 Chong Yidong <cyd@gnu.org>
5537 * window.c (Fwindow_combination_limit): Make first argument

5560 (compute_line_metrics): Call row_hash, instead of computing the
5563 * dispnew.c (verify_row_hash): Call row_hash for computing the
5564 hash code of a row, instead of duplicating code from xdisp.c.
5566 * dispextern.h (row_hash): Add prototype.

5602 * image.c (imagemagick_load_image): Fix typo.
5604 2011-11-14 Eli Zaretskii <eliz@gnu.org>
5606 * xdisp.c (display_line): Move the call to
5607 highlight_trailing_whitespace before the call to
5608 compute_line_metrics, since the latter needs to see the final
5609 faces of all the glyphs to compute ROW's hash value.
5610 Fixes assertion violations in row_equal_p. (Bug#10035)
5612 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
5614 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,

5619 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
5620 with user-defined heap size. Bump the default size of the temacs
5621 heap to 27MB, to avoid memory warning when running temacs.

5671 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
5673 Avoid some portability problems by eschewing 'extern inline' functions.
5674 The trivial performance wins aren't worth the portability hassles; see
5675 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
5677 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

5679 (window_box_right, window_box_right_offset): Undo previous change,
5680 by removing the "extern"s.
5681 * intervals.c (adjust_intervals_for_insertion)
5682 (adjust_intervals_for_deletion): Undo previous change,
5683 making these static again.
5684 (offset_intervals, temp_set_point_both, temp_set_point)
5685 (copy_intervals_to_string): No longer inline.
5686 * xdisp.c (window_text_bottom_y, window_box_width)

5752 (window_box_right, window_box_right_offset): Declare extern.
5753 Otherwise, these inline functions do not conform to C99 and
5754 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
5755 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
5756 * intervals.c (adjust_intervals_for_insertion)

5759 (static_offset_intervals): Remove.
5760 (offset_intervals): Rewrite using the old contents of
5761 static_offset_intervals. The old version didn't conform to C99
5762 because an extern inline function contained a reference to an
5763 identifier with static linkage.

5785 (Fwindow_vscroll): Doc fix.
5786 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
5787 argument, since it makes no sense to pass a live window and for
5788 consistency with window-child.

5816 (unwind_create_frame): New function (Bug#9943).
5817 (Fx_create_frame): Restructure code to be more similar to the one in
5818 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).
5819 Initialize image_cache_refcount if GLYPH_DEBUG (Bug#9943).
5820 Move terminal->reference_count++ just before making the frame official

5915 (x_error_handler): Ignore BadMatch for X_SetInputFocus for
5916 HAVE_GTK3 (Bug#9869).
5918 * gtkutil.c (xg_win_to_widget, xg_event_is_for_menubar): Initialize
5919 type to GDK_NOTHING so valgrind does not complain (Bug#9901).
5921 * xterm.h (x_display_info): Add Xatom_net_wm_state_hidden (Bug#9893).
5923 * xterm.c: Declare x_handle_net_wm_state to return int.
5924 (handle_one_xevent): Check if we are iconified but don't have
5925 _NET_WM_STATE_HIDDEN. If do, treat as deiconify (Bug#9893).
5926 (get_current_wm_state): Return non-zero if not hidden,
5927 check for _NET_WM_STATE_HIDDEN (Bug#9893).
5928 (do_ewmh_fullscreen): Ignore return value from get_current_wm_state.
5929 (x_handle_net_wm_state): Return what get_current_wm_state returns.
5930 (x_term_init): Initialize dpyinfo->Xatom_net_wm_state_hidden.
5932 2011-10-29 Paul Eggert <eggert@cs.ucla.edu>
5934 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
5935 so that this new function doesn't get optimized away by a
5936 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
5938 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
5940 * frame.h (MOUSE_HL_INFO): Remove excess parens.
5942 2011-10-29 Eli Zaretskii <eliz@gnu.org>
5944 Fix the `xbytecode' command.
5945 * .gdbinit (xprintbytestr): New command.
5946 (xwhichsymbols): Rename from `which'; all callers changed.
5947 (xbytecode): Print the byte-code string as well.
5949 2011-10-29 Kim Storm <storm@cua.dk>
5951 * alloc.c (which_symbols): New function.
5953 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
5955 * minibuf.c (read_minibuf_noninteractive): Allow reading empty
5958 2011-10-29 Glenn Morris <rgm@gnu.org>
5960 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
5961 Not clear what it was for, and it causes various bugs. (Bug#9839)
5963 2011-10-28 Eli Zaretskii <eliz@gnu.org>
5965 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
5966 possible random value that matches one of those tested as
5967 condition to clear the mouse face.
5969 2011-10-28 Chong Yidong <cyd@gnu.org>
5971 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.
5973 2011-10-28 Dan Nicolaescu <dann@ics.uci.edu>
5975 * window.c (make_window): Initialize phys_cursor_on_p.
5977 2011-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
5979 * lisp.h (struct Lisp_Symbol): Update comments.
5981 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
5983 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
5985 2011-10-28 Eli Zaretskii <eliz@gnu.org>
5987 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
5988 <oslsachem@gmail.com> for helping to debug this.
5990 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
5991 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
5992 (g_b_init_get_glyph_outline_w): New static variables.
5993 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
5994 (GetGlyphOutlineW_Proc): New typedefs.
5995 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
5996 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
5998 (w32font_open_internal, compute_metrics):
5999 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
6000 instead of calling the "wide" APIs directly.
6002 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
6004 * w32.h (syms_of_w32font): Add prototype.
6006 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
6008 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
6009 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
6010 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
6011 (Fmove_to_window_line): Doc fix.
6013 2011-10-27 Chong Yidong <cyd@gnu.org>
6015 * process.c (make_process): Set gnutls_state to NULL.
6017 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
6018 non-NULL, regardless of GNUTLS_INITSTAGE.
6019 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
6020 an error. Set process slots as soon as we allocate them.
6022 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
6024 2011-10-27 Chong Yidong <cyd@gnu.org>
6026 * gnutls.c (emacs_gnutls_deinit): New function.
6027 Deallocate credentials structures as well as calling gnutls_deinit.
6028 (Fgnutls_deinit, Fgnutls_boot): Use it.
6030 * process.c (make_process): Initialize GnuTLS credentials to NULL.
6031 (deactivate_process): Call emacs_gnutls_deinit.
6033 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
6035 * image.c (x_create_x_image_and_pixmap):
6036 * w32.c (sys_rename, w32_delayed_load):
6037 * w32font.c (fill_in_logfont):
6038 * w32reg.c (x_get_string_resource): Silence compiler warnings.
6040 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
6042 * w32fns.c (w32_default_color_map): New function,
6043 extracted from Fw32_default_color_map.
6044 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
6046 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
6048 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
6050 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
6052 * keyboard.c (test_undefined): New function (bug#9751).
6053 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
6055 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
6057 * sysdep.c (init_sys_modes): Fix the check for the controlling
6058 terminal (Bug#6649).
6060 2011-10-20 Eli Zaretskii <eliz@gnu.org>
6062 * dispextern.h (struct bidi_it): New member next_en_type.
6064 * bidi.c (bidi_line_init): Initialize the next_en_type member.
6065 (bidi_resolve_explicit_1): When next_en_pos is valid for the
6066 current character, check also for next_en_type being WEAK_EN.
6067 (bidi_resolve_weak): Don't enter the expensive loop if the current
6068 position is before next_en_pos. Record the bidi type of the first
6069 non-ET, non-BN character we find, in addition to its position.
6070 (bidi_level_of_next_char): Invalidate next_en_type when
6071 next_en_pos is over-stepped.
6073 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
6075 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
6076 * editfns.c: Rewrite current-time-zone so that it invokes
6077 the equivalent of (format-time-string "%Z") to get the time zone name.
6078 This fixes a bug when the time zone name contains characters that
6079 need converting from the system time locale to Emacs internal format.
6080 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
6081 that patch fixed format-time-string to do the conversion, but
6082 I forgot to fix current-time-zone.
6083 (format_time_string): New function, containing most of
6084 what Fformat_time_string used to contain.
6085 (Fformat_time_string): Rewrite in terms of format_time_string.
6086 This doesn't change this function's behavior.
6087 (current-time-zone): Rewrite to use format_time_string.
6088 This fixes the bug reported by Michael Schierl in
6089 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
6090 Jason Rumney's 2007-06-07 change worked around this bug, but
6092 * systime.h (tzname, timezone): Remove no-longer-used declarations.
6094 2011-10-19 Eli Zaretskii <eliz@gnu.org>
6096 * xdisp.c (start_display): If the character at POS is displayed
6097 via a display vector, reset IT->current.dpvec_index to zero.
6098 (try_window_reusing_current_matrix): If a line ends in a display
6099 vector or the next line starts in a display vector, continue
6100 redrawing the window even though the character position of
6101 start_row was reached.
6104 2011-10-18 Chong Yidong <cyd@gnu.org>
6106 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
6107 with nobreak-char-display too.
6109 2011-10-18 Eli Zaretskii <eliz@gnu.org>
6111 Fix part 3 of bug#9771.
6112 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
6113 (bidi_resolve_neutral): Don't enter the expensive loop looking for
6114 non-neutral characters if the current character is a paragraph
6115 separator (a.k.a. Newline). This avoids running the same
6116 expensive loop twice, once when we consume the preceding newline
6117 and the other time when the line actually needs to be displayed.
6118 Avoid the loop when we see neutrals on the base embedding level
6119 following a character whose directionality is the same as the
6120 paragraph's. This avoids running the expensive loop when a line
6121 ends in a long sequence of neutrals, like control characters.
6122 Add assertion against STRONG_AL type. Slightly rearrange code
6123 that determines the type of a neutral given the first non-neutral
6125 (bidi_level_of_next_char): Set next_en_pos to zero when
6126 invalidating its info.
6128 2011-10-17 Eli Zaretskii <eliz@gnu.org>
6130 * xdisp.c (push_display_prop): Determine whether to record string
6131 or buffer position by IT->string, not by IT->method. Allow
6132 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
6133 (move_it_vertically_backward): Don't look for character position
6134 immediately after the newline when in a continuation line.
6137 2011-10-15 Martin Rudalics <rudalics@gmx.at>
6139 * window.c (coordinates_in_window): Rewrite and delabelize
6140 vertical border check. (Bug#5357) (Bug#9618)
6142 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
6144 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
6145 errors in XSetWindowBorder (bug#9310).
6147 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
6149 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
6150 avoid crash when xmalloc overrun checking is enabled.
6152 2011-10-13 Eli Zaretskii <eliz@gnu.org>
6154 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
6155 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
6156 cursor motion with <left> and <right> arrow keys.
6158 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
6159 some callers set that themselves.
6161 2011-10-12 Eli Zaretskii <eliz@gnu.org>
6163 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
6164 display string and the previous row comes from the same string and
6165 is empty. (Bug#9739) (Bug#9738)
6167 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
6169 * doc.c (get_doc_string): Encode file name (bug#9735).
6171 2011-10-12 Eli Zaretskii <eliz@gnu.org>
6173 * bidi.c (bidi_level_of_next_char):
6174 * xdisp.c (get_visually_first_element): Remove old incorrect
6175 comments regarding the Unicode Line Separator character.
6177 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
6179 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
6181 * alloc.c (Fgc_status): Do not access beyond zombies array
6182 boundary if nzombies > MAX_ZOMBIES.
6183 * alloc.c (dump_zombies): Add missing format specifier.
6185 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
6187 * xdisp.c (set_cursor_from_row): Simplify conditionals,
6188 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
6190 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
6191 Some packages use them to denote characters with modifiers.
6193 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
6195 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
6196 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
6197 matching a pp-number. Rename parameter var to var1.
6199 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
6201 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
6203 2011-10-08 Glenn Morris <rgm@gnu.org>
6205 * callint.c (Fcall_interactively): Give a more explicit error for the
6206 'c' case with a non-character input. (Bug#8479)
6208 2011-10-08 Eli Zaretskii <eliz@gnu.org>
6210 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
6212 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
6213 lines that are hscrolled on the left.
6215 * dispnew.c (buffer_posn_from_coords): Account for a possible
6216 presence of header-line. (Bug#4426)
6218 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
6220 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
6221 Don't advertise functionality which we discourage or doesn't work.
6223 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
6225 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
6226 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
6227 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
6228 this makes Emacs dump core during garbage collection on rare
6229 occasions. sizeof is obviously inferior to offsetof here, so
6230 stick with offsetof.
6231 (GC_POINTER_ALIGNMENT): New macro.
6232 (mark_memory): Omit 3rd (offset) arg; caller changed.
6233 Don't assume EMACS_INT alignment is the same as pointer alignment.
6235 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
6237 * keyboard.c (read_key_sequence_remapped): New var.
6238 (read_key_sequence): Compute remapping in the right buffer.
6239 (command_loop_1): Use read_key_sequence's remapping directly.
6241 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
6243 * dired.c (file_name_completion): Don't expand file name.
6244 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
6245 before checking file name handler.
6247 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
6248 they've been requested explicitly (bug#9591).
6250 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
6252 * keymap.c (Fsingle_key_description): Use make_specified_string
6253 instead of build_string to build string from push_key_description.
6256 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
6258 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
6259 This fixes a Y2038 bug on 64-bit hosts.
6260 * buffer.c (reset_buffer):
6261 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
6262 (Fclear_buffer_auto_save_failure):
6263 Use 0, not -1, to represent an unset failure time, since time_t
6264 might not be signed.
6266 Remove dependency on glibc malloc internals.
6267 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6268 Move back here from lisp.h, but with their new implementations.
6269 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
6270 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
6271 * charset.c (charset_table_init): New static var.
6272 (syms_of_charset): Use it instead of xmalloc. This removes a
6273 dependency on glibc malloc internals. See Eli Zaretskii's comment in
6274 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
6275 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6276 Move back to alloc.c.
6277 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
6278 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
6280 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
6282 * nsterm.m (windowDidResize): Call x_set_window_size only when
6283 ns_in_resize is true. Otherwise set pixelwidth/height and
6284 call change_frame_size (Bug#9628).
6286 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
6288 Port --enable-checking=all to Fedora 14 x86-64.
6289 * charset.c (syms_of_charset): Also account for glibc malloc's
6290 internal overhead when calculating the initial malloc maximum.
6292 Port --enable-checking=all to Fedora 14 x86.
6293 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6295 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
6296 (overrun_check_realloc, overrun_check_free):
6297 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
6298 That way, xmalloc returns a properly-aligned pointer even if
6299 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
6300 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
6301 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
6302 into account when calculating the initial malloc maximum.
6303 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6304 Move here from alloc.c, so that charset.c can use it too.
6305 Properly align; the old code wasn't right for common 32-bit hosts
6306 when configured with --enable-checking=all.
6307 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
6308 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
6310 2011-09-29 Eli Zaretskii <eliz@gnu.org>
6312 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
6315 2011-09-28 Eli Zaretskii <eliz@gnu.org>
6317 * xdisp.c (compute_display_string_end): If there's no display
6318 string at CHARPOS, return -1.
6320 * bidi.c (bidi_fetch_char): When compute_display_string_end
6321 returns a negative value, treat the character as a normal
6322 character not covered by a display string. (Bug#9624)
6324 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
6326 * lread.c (Fread_from_string): Fix typo in docstring.
6328 2011-09-27 Eli Zaretskii <eliz@gnu.org>
6330 * xdisp.c (handle_invisible_prop): If invisible text ends on a
6331 newline, reseat the iterator instead of bidi-iterating there one
6332 character at a time. (Bug#9610)
6333 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
6334 TO_CHARPOS if the bidi iterator is at base embedding level.
6336 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
6338 * lread.c (readevalloop): Use correct code for NBSP.
6339 (read1): Likewise. (Bug#9608)
6341 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
6343 * dbusbind.c (Fdbus_register_signal): When service is not
6344 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
6346 2011-09-25 Glenn Morris <rgm@gnu.org>
6348 * buffer.c (truncate-lines): Doc fix.
6350 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
6352 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
6353 (Fset_window_next_buffers): Doc fix.
6355 2011-09-24 Glenn Morris <rgm@gnu.org>
6357 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
6359 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
6361 Fix minor problems found by static checking.
6362 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
6363 * indent.c (Fvertical_motion): Fix == vs = typo.
6365 2011-09-24 Eli Zaretskii <eliz@gnu.org>
6367 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
6368 Default value is now t. Doc fix.
6370 * indent.c (Fvertical_motion): Compute and apply the overshoot
6371 logic when moving up, not only when moving down. Fix the
6372 confusing name and values of the it_overshoot_expected variable;
6373 logic changes accordingly. (Bug#9254) (Bug#9549)
6375 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
6376 CHARPOS is covered by a display string which includes newlines.
6377 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
6378 is covered by a display string with embedded newlines.
6380 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
6382 * dbusbind.c (Fdbus_register_signal): Add match rule to
6383 Vdbus_registered_objects_table. (Bug#9581)
6384 (Fdbus_register_method, Vdbus_registered_objects_table):
6387 2011-09-24 Jim Meyering <meyering@redhat.com>
6389 do not ignore write error for any output size
6390 The previous change was incomplete.
6391 While it makes emacs --batch detect the vast majority of stdout
6392 write failures, errors were still ignored whenever the output size is
6393 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
6394 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
6395 && echo FAIL: ignored write error
6396 FAIL: ignored write error
6397 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
6398 && echo FAIL: ignored write error
6399 FAIL: ignored write error
6400 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
6402 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
6404 * emacs.c (Fkill_emacs): In noninteractive mode exit
6405 non-successfully if a write error occurred on stdout. (Bug#9574)
6407 2011-09-21 Eli Zaretskii <eliz@gnu.org>
6409 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
6412 * dispextern.h (struct it): Update the comment documenting what
6415 2011-09-20 Eli Zaretskii <eliz@gnu.org>
6417 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
6418 a display string, extend search for cursor position to end of row.
6419 (find_row_edges): If the row ends in a newline from a display
6420 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
6421 Handle the case of a display string with multiple newlines.
6422 (Fcurrent_bidi_paragraph_direction): Fix search for previous
6423 non-empty line. Fixes confusing cursor motion with arrow keys at
6424 the beginning of a line that starts with whitespace.
6426 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
6428 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
6431 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
6433 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
6436 2011-09-18 Eli Zaretskii <eliz@gnu.org>
6438 * xdisp.c (display_line): Record maximum and minimum buffer
6439 positions even if no glyphs were produced (e.g., by a zero-width
6440 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
6441 buffer positions that will be removed from the glyph row because
6443 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
6444 column is beyond frame width: don't subtract 1 "pixel" when
6445 computing width of the stretch.
6446 (reseat_at_next_visible_line_start): Undo the change made on
6447 2011-09-17 that saved paragraph information and restored it after
6448 the call to `reseat'. (Bug#9545)
6450 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6452 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
6453 and turn window cursor on if cleared (Bug#9415).
6455 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
6457 * search.c (boyer_moore): Take unibyte characters from pattern
6458 literally. (Bug#9458)
6460 2011-09-18 Eli Zaretskii <eliz@gnu.org>
6462 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
6464 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
6466 Fix minor problem found by static checking.
6467 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
6468 initialized, to pacify gcc -Wuninitialized.
6470 * fileio.c: Report proper errno when syscall falls.
6471 (Finsert_file_contents): Save and restore errno,
6472 so that report_file_error outputs the correct diagnostic.
6473 (Fwrite_region) [CLASH_DETECTION]: Likewise.
6475 2011-09-18 Eli Zaretskii <eliz@gnu.org>
6477 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
6479 2011-09-17 Eli Zaretskii <eliz@gnu.org>
6481 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
6482 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
6484 2011-09-17 Eli Zaretskii <eliz@gnu.org>
6486 * xdisp.c (reseat_at_next_visible_line_start): Keep information
6487 about the current paragraph and restore it after the call to reseat.
6489 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
6490 (bidi_find_paragraph_start): Search back for paragraph beginning
6491 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
6492 (bidi_move_to_visually_next): Only trigger paragraph-related
6493 computations when the last character is a newline or at EOB, not
6494 just any NEUTRAL_B. (Bug#9470)
6496 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
6497 truncated lines if point is covered by a display string. (Bug#9524)
6499 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
6501 * xselect.c: Relax test for outgoing X longs (Bug#9498).
6502 (cons_to_x_long): New function.
6503 (lisp_data_to_selection_data): Use it. Correct the test for
6504 short-versus-long data; it was negated. Break out of vector
6505 loop, for efficiency, when a long datum is discovered.
6507 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
6509 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
6511 2011-09-16 Eli Zaretskii <eliz@gnu.org>
6513 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
6514 GCC PR/17406) by declaring this function with external scope.
6516 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
6518 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
6519 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
6521 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
6523 * editfns.c (Fformat): Correctly handle text properties on "%%".

6533 of TAB characters in a composition.
6535 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
6537 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
6538 This occurs when processing a multibyte format.
6539 Problem reported by Wolfgang Jenker.
6541 2011-09-15 Johan Bockgård <bojohan@gnu.org>
6543 * xdisp.c (try_cursor_movement): Only check for exact match if
6544 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
6546 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
6548 Remove unused external symbols.
6549 * dispextern.h (calc_pixel_width_or_height): Remove decl.
6550 * xdisp.c (calc_pixel_width_or_height): Now static.
6551 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
6552 * indent.c (check_display_width):
6553 * w32term.c: Fix comment to match code.
6554 * xterm.c, xterm.h (x_catching_errors): Remove.
6556 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
6558 * xselect.c: Use signed conversions more consistently (Bug#9498).
6559 (selection_data_to_lisp_data): Assume incoming selection data are
6560 signed integers, not unsigned. This is to be consistent with
6561 outgoing selection data, which was modified to use signed integers
6562 in as part of the fix to Bug#9196 in response to Jan D.'s comment
6563 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
6564 expects long, not unsigned long.
6566 2011-09-14 Eli Zaretskii <eliz@gnu.org>
6568 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
6569 computation of loop end. Reported by Johan Bockgård
6572 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
6574 * frame.c (Fother_visible_frames_p): Function deleted.
6576 2011-09-12 Eli Zaretskii <eliz@gnu.org>
6578 * indent.c (compute_motion): Process display vector front to back
6579 rather than the other way around. (Bug#2496)
6581 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
6583 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
6585 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
6587 * minibuf.c (Fread_from_minibuffer): Doc fix.
6589 2011-09-11 Eli Zaretskii <eliz@gnu.org>
6591 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
6592 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
6594 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
6596 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
6597 value for non-existent files.
6599 2011-09-11 Eli Zaretskii <eliz@gnu.org>
6601 * fileio.c (Finsert_file_contents): If the file cannot be opened,
6602 set its "size" to -1. This will set the modtime_size field of
6603 the corresponding buffer to -1, which is what
6604 verify-visited-file-modtime expects for files that do not exist.
6607 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
6609 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
6611 * lisp.h: ... from here. push_key_description is no longer
6612 defined in keyboard.c, so its declaration should not be in
6613 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
6614 logically belongs with push_key_description.
6616 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
6618 * buffer.h: Include <sys/types.h> instead of <time.h>.
6619 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
6620 Problem reported by Herbert J. Skuhra.
6622 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
6624 * xml.c (parse_region): Make the parsing work for
6625 non-comment-starting XML files again (bug#9144).
6627 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
6629 * image.c (gif_load): Fix calculation of bottom and right corner.
6632 2011-09-10 Eli Zaretskii <eliz@gnu.org>
6634 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
6635 redisplay in small windows.
6637 2011-09-09 Eli Zaretskii <eliz@gnu.org>
6639 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
6641 2011-09-08 Martin Rudalics <rudalics@gmx.at>
6643 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
6644 Operate on live windows only.
6646 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
6648 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
6650 2011-09-07 Eli Zaretskii <eliz@gnu.org>
6652 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
6653 only under bidi iteration.
6655 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
6657 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
6659 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
6661 isnan: Fix porting problem to Solaris 10 with bundled gcc.
6662 Without this fix, the command to link temacs failed due to an
6663 undefined symbol __builtin_isnan. This is because
6664 /usr/include/iso/math_c99.h #defines isnan(x) to
6665 __builtin_isnan(x), but the bundled gcc, which identifies itself
6666 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
6668 * floatfns.c (isnan): #undef, and then #define to a clone of
6670 (Fisnan): Always define, since it's always available now.
6671 (syms_of_floatfns): Always define isnan at the Lisp level.
6673 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
6675 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
6677 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
6679 * fileio.c: Fix bugs with large file offsets (Bug#9428).
6680 The previous code assumed that file offsets (off_t values) fit in
6681 EMACS_INT variables, which is not true on typical 32-bit hosts.
6682 The code messed up by falsely reporting buffer overflow in cases
6683 such as (insert-file-contents "big" nil 1 2) into an empty buffer
6684 when "big" contains more than 2**29 bytes, even though this
6685 inserts just one byte and does not overflow the buffer.
6686 (Finsert_file_contents): Store file offsets as off_t
6687 values, not as EMACS_INT values. Check for overflow when
6688 converting between EMACS_INT and off_t. When checking for
6689 buffer overflow or for overlap, take the offsets into account.
6690 Don't use EMACS_INT for small values where int suffices.
6691 When checking for overlap, fix a typo: ZV was used where
6692 ZV_BYTE was intended.
6693 (Fwrite_region): Don't assume off_t fits into 'long'.
6694 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
6696 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
6698 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
6700 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
6702 sprintf-related integer and memory overflow issues (Bug#9412).
6704 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
6705 (esprintf, exprintf, evxprintf): New functions.
6706 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
6707 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
6708 (modify_event_symbol): Do not assume that the length of
6709 name_alist_or_stem is safe to alloca and fits in int.
6710 (Fexecute_extended_command): Likewise for function name and binding.
6711 (Frecursion_depth): Wrap around reliably on integer overflow.
6712 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
6713 since some callers pass EMACS_INT values.
6714 (Fsingle_key_description): Don't crash if symbol name contains more
6715 than MAX_ALLOCA bytes.
6716 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
6717 (get_minibuffer): Arg is now EMACS_INT, not int.
6718 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
6719 (esprintf, exprintf, evxprintf): New decls.
6720 * window.h (command_loop_level, minibuf_level): Reflect API changes.
6722 * dbusbind.c (signature_cat): New function.
6723 (xd_signature, Fdbus_register_signal):
6724 Do not overrun buffer; instead, report string overflow.
6726 * dispnew.c (add_window_display_history): Don't overrun buffer.
6727 Truncate instead; this is OK since it's just a log.
6729 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
6730 even if the time zone offset is outlandishly large.
6731 Don't mishandle offset == INT_MIN.
6733 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
6734 when creating daemon; the previous buffer-overflow check was incorrect.
6736 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
6737 which has the guts of the old verror function.
6739 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
6740 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
6742 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
6743 (font_unparse_xlfd): Don't blindly alloca long strings.
6744 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
6745 fits in int, when using sprintf. Use single snprintf to count
6746 length of string rather than counting it via multiple sprintfs;
6747 that's simpler and more reliable.
6748 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
6749 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
6750 sprintf, in case result does not fit in int.
6752 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
6753 (fontset_from_font): Print it.
6755 * frame.c (tty_frame_count): Now printmax_t, not int.
6756 (make_terminal_frame, set_term_frame_name): Print it.
6757 (x_report_frame_params): In X, window IDs are unsigned long,
6758 not signed long, so print them as unsigned.
6759 (validate_x_resource_name): Check for implausibly long names,
6760 and don't assume name length fits in 'int'.
6761 (x_get_resource_string): Don't blindly alloca invocation name;
6762 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
6765 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
6766 (xg_check_special_colors, xg_set_geometry):
6767 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
6769 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
6770 Use esprintf, not sprintf, in case result does not fit in int.
6772 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
6773 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
6774 it as a large positive number.
6775 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
6776 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
6778 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
6779 in case result does not fit in int.
6781 * print.c (float_to_string): Detect width overflow more reliably.
6782 (print_object): Make sprintf buffer a bit bigger, to avoid potential
6783 buffer overrun. Don't assume list length fits in 'int'. Treat
6784 print length of 0 as 0, not as infinity; to be consistent with other
6785 uses of print length in this function. Don't overflow print length
6786 index. Don't assume hash table size fits in 'long', or that
6787 vectorlike size fits in 'unsigned long'.
6789 * process.c (make_process): Use printmax_t, not int, to format
6790 process-name gensyms.
6792 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
6794 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
6795 to avoid potential buffer overrun.
6797 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
6798 if X resource line is longer than 512 bytes.
6800 * xfns.c (x_window): Make sprintf buffer a bit bigger
6801 to avoid potential buffer overrun.
6803 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
6805 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
6807 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
6809 Integer overflow fixes for scrolling, etc.
6810 Without these, Emacs silently mishandles large integers sometimes.
6811 For example, "C-u 4294967297 M-x recenter" was treated as if
6812 it were "C-u 1 M-x recenter" on a typical 64-bit host.
6814 * xdisp.c (try_window_id): Check Emacs fixnum range before
6815 converting to 'int'.
6817 * window.c (window_scroll_line_based, Frecenter):
6818 Check that an Emacs fixnum is in range before assigning it to 'int'.
6819 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
6820 values converted from Emacs fixnums.
6821 (Frecenter): Don't wrap around a line count if it is out of 'int'
6822 range; instead, treat it as an extreme value.
6823 (Fset_window_configuration, compare_window_configurations):
6824 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
6826 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
6827 that can exceed INT_MAX. Check that EMACS_INT value is in range
6828 before assigning it to the (possibly-narrower) index.
6829 (match_limit): Don't assume that a fixnum can fit in 'int'.
6831 * print.c (print_object): Use ptrdiff_t, not int, for index that can
6834 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
6835 (Fvertical_motion): Don't wrap around LINES values that don't fit
6836 in 'int'. Instead, treat them as extreme values. This is good
6837 enough for windows, which can't have more than INT_MAX lines anyway.
6839 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
6841 * Require libxml/parser.h to avoid compilation warning.
6843 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
6845 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
6846 since this reportedly can destroy thread storage.
6848 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
6850 * syntax.c (find_defun_start): Update all cache variables if
6851 exiting early (Bug#9401).
6853 2011-08-30 Eli Zaretskii <eliz@gnu.org>
6855 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
6857 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
6858 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
6859 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
6861 * term.c (tty_append_glyph): New function.
6862 (produce_stretch_glyph): Static function and its prototype deleted.
6864 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
6867 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
6869 * image.c (parse_image_spec): Check for nonnegative, not for positive,
6870 when checking :margin (Bug#9390).
6871 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
6872 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
6873 so that the name doesn't mislead. All uses changed.
6875 2011-08-28 Johan Bockgård <bojohan@gnu.org>
6877 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
6880 2011-08-27 Eli Zaretskii <eliz@gnu.org>
6882 * xdisp.c (move_it_to): Don't bail out early when reaching
6883 position beyond to_charpos, if we are scanning backwards.
6884 (move_it_vertically_backward): When DY == 0, make sure we get to
6885 the first character in the line after the newline.
6887 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
6889 * ccl.c: Improve and simplify overflow checking (Bug#9196).
6890 (ccl_driver): Do not generate an out-of-range pointer.
6891 (Fccl_execute_on_string): Remove unnecessary check for
6892 integer overflow, noted by Stefan Monnier in
6893 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
6894 Remove a FIXME that didn't need fixing.

6901 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
6903 Integer and memory overflow issues (Bug#9196).
6905 * doc.c (get_doc_string): Rework so that
6906 get_doc_string_buffer_size is the actual buffer size, rather than
6907 being 1 less than the actual buffer size; this makes xpalloc more
6910 * image.c (x_allocate_bitmap_record, cache_image):
6911 * xselect.c (Fx_register_dnd_atom):
6912 Simplify previous changes by using xpalloc.
6914 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
6915 since either will do and ptrdiff_t is convenient with xpalloc.
6917 * charset.c (charset_table_size)
6918 (struct charset_sort_data.priority): Now ptrdiff_t.
6919 (charset_compare): Don't overflow if priorities differ greatly.
6920 (Fsort_charsets): Don't assume list length fits in int.
6921 Check for size-calculation overflow when allocating sort data.
6922 (syms_of_charset): Allocate an initial charset table that is
6923 just under 64 KiB, to avoid problems with glibc malloc and mmap.
6925 * cmds.c (internal_self_insert): Check for size-calculation overflow.
6927 * composite.h (struct composition.glyph_len): Now int, not unsigned.
6928 The actual value is always <= INT_MAX, and leaving it unsigned made
6929 overflow checking harder.
6931 * dispextern.h (struct glyph_matrix.rows_allocated)
6932 (struct face_cache.size): Now ptrdiff_t, for convenience in use
6933 with xpalloc. The values are still always <= INT_MAX.
6935 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
6937 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
6938 (SAFE_NALLOCA): New macro.
6940 * region-cache.c (struct boundary.pos, find_cache_boundary)
6941 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
6942 (set_cache_region, invalidate_region_cache)
6943 (revalidate_region_cache, know_region_cache, region_cache_forward)
6944 (region_cache_backward, pp_cache):
6945 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
6946 so that ptrdiff_t * can be passed to xpalloc.
6947 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
6948 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
6949 (pp_cache): Don't assume cache_len fits in int.
6950 * region-cache.h: Adjust extern decls to match.

6956 (xnmalloc, xnrealloc, xpalloc): New functions.
6958 * bidi.c (bidi_shelve_header_size): New constant.

6960 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
6962 * bidi.c (bidi_cache_shrink):
6963 * buffer.c (overlays_at, overlays_in, record_overlay_string)
6965 Don't update size of array until after memory allocation succeeds,
6966 because xmalloc/xrealloc may not return.
6967 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
6968 now that we have proper integer overflow checking.
6969 (record_overlay_string, overlay_strings): Catch overflows when
6970 calculating size of overlay_str_buf.
6972 * callproc.c (Fcall_process): Check for size overflow when
6973 calculating size of args2.
6974 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
6975 Normally we prefer signed values, but sticking with ptrdiff_t would
6976 require adding more-complicated checks.
6978 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
6979 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
6980 Redo buffer-overflow calculations to avoid integer overflow.
6981 Add a FIXME comment where memory seems to be over-allocated.
6983 * character.c (Fstring): Check for size-calculation overflow.
6985 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
6986 unnecessary integer overflow. Check for size overflow.
6987 (encode_coding_object): Don't update size until xmalloc succeeds.
6989 * composite.c (get_composition_id): Check for overflow in glyph
6990 length calculations.

6994 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
6995 (scrolling_window): Check for overflow in size calculations.
6996 (line_draw_cost, realloc_glyph_pool, add_row_entry):

7008 (get_doc_string): Check for size calculation overflow.
7009 Don't update size until allocation succeeds.
7010 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
7011 EMACS_INT, where ptrdiff_t will do.
7012 (Fsubstitute_command_keys): Check for string overflow.
7014 * editfns.c (set_time_zone_rule): Don't assume environment length
7016 (message_length): Now ptrdiff_t, not int.
7017 (Fmessage_box): Don't update size until allocation succeeds.
7018 Don't assume message length fits in int.
7019 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
7021 * emacs.c (main): Do not reallocate argv, since there is a null at
7022 the end that can be overwritten, and this way there's no need to
7023 worry about size-calculation overflow.
7024 (sort_args): Check for size-calculation overflow.
7026 * eval.c (init_eval_once, grow_specpdl): Don't update size until
7028 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
7030 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
7031 (x_set_scroll_bar_width, x_figure_window_size):
7032 Check for integer overflow.
7033 (x_set_alpha): Do not assume XINT fits in int.
7035 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
7036 This is for the members text_lines, text_cols, total_lines, total_cols,
7037 where the system imposes an 'int' limit.
7039 * fringe.c (Fdefine_fringe_bitmap):
7040 Don't update size until alloc works.
7042 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
7043 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
7045 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
7046 Check for size-calculation overflow.
7047 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
7048 do, as we prefer signed integers.
7049 (id_to_widget.max_size, id_to_widget.used)
7050 (xg_store_widget_in_map, xg_remove_widget_from_map)
7051 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
7052 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
7053 Use and return ptrdiff_t, not int.
7054 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
7055 * gtkutil.h: Change prototypes to match the above.
7057 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
7058 are duplicate now that they've been promoted to lisp.h.
7059 (x_allocate_bitmap_record, x_alloc_image_color)
7060 (make_image_cache, cache_image, xpm_load):

7071 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
7072 Use ptrdiff_t, not int, to count maps.

7102 (Fset_match_data): Don't assume list lengths fit in 'int'.
7104 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
7105 for command line length. Do not attempt to address one before the

7111 (encode_terminal_code, calculate_costs): Check for size
7112 calculation overflow.

7141 (Fx_change_window_property): Use ptrdiff_t, not int, to count
7142 sizes, since they can exceed INT_MAX in size. Check for size

7146 (xg_select): Check for size calculation overflow.
7147 Don't update size until alloc done.
7149 * xrdb.c (get_environ_db): Don't assume path length fits in int,

7153 (X_LONG_MIN): New macros.
7154 Use them to make the following changes clearer.
7155 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.

7157 future maintainers not to raise the value too much later.
7158 (SELECTION_QUANTUM): Remove, replacing with ...
7159 (selection_quantum): ... new function, which avoids overflow.
7161 (struct selection_data.size): Now ptrdiff_t, not int, to avoid

7175 (lisp_data_to_selection_data, x_property_data_to_lisp):
7176 Check for size-calculation overflow.

7179 Don't store size until memory allocation succeeds.
7180 (x_get_window_property): Plug memory leak on memory exhaustion.
7181 Don't double-block input; malloc is safe here. Don't assume 2**34
7182 - 4 fits in unsigned long. Add an xassert to check
7183 XGetWindowProperty overflow. Be more careful about overflow
7184 calculations, and distinguish size from memory overflow better.
7185 (receive_incremental_selection): When tracing, don't assume
7186 unsigned int is less than INT_MAX.
7187 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
7188 harmful) conversions of unsigned short to int.
7189 (lisp_data_to_selection_data): Don't assume that integers
7190 in the range -65535 through -1 fit in an X unsigned short.
7191 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
7192 result parameters unless successful. Rely on cons_to_unsigned
7193 to report problems with elements; the old code wasn't right anyway.
7194 (x_check_property_data): Check for int overflow; we cannot use
7195 a wider type due to X limits.

7228 * lisp.h (hash_lookup, hash_put):
7229 * minibuf.c (Ftest_completion):
7230 Use ptrdiff_t for hash table indexes, not int (which is too
7231 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
7232 32-bit --with-wide-int hosts).

7243 with outlandish widths.
7244 * character.h (sanitize_tab_width): Rename from sanitize_width,
7245 now that we have two such functions. All uses changed.

7270 (make_lispy_movement): Use same integer type in forward decl
7271 that is used in the definition.
7272 (read_key_sequence, keyremap_step):
7273 Change bufsize argument back to int, undoing my 2011-03-30 change.
7274 We prefer signed types, and int is wide enough here.
7275 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
7276 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
7277 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
7278 length, not size_t. Use ptrdiff_t for index, not int.
7279 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
7280 possibility of integer overflow.

7308 Prefer int to unsigned where either will do.
7309 (tiff_handler): New function, combining the cores of the
7310 old tiff_error_handler and tiff_warning_handler.
7311 This function is rewritten to use vsnprintf and thereby avoid
7312 stack buffer overflows. It uses only the features of vsnprintf
7313 that are common to both POSIX and native Microsoft.
7314 (tiff_error_handler, tiff_warning_handler): Use it.
7315 (tiff_load, gif_load, imagemagick_load_image):
7316 Don't assume :index value fits in 'int'.
7317 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.

7319 the integer types that MagickCropImage accepts. Don't assume
7320 Vimagemagick_render_type has a nonnegative value. Don't assume
7321 size_t fits in 'long'.
7322 (gs_load): Use printmax_t to print the widest integers possible.

7336 (handle_single_display_spec): If the display spec is of the form
7337 `(space ...)', and specifies display in the text area, return 2
7339 (try_cursor_movement): Check for the need to scroll more
7340 accurately, and prefer exact match for point under bidi.
7341 Don't advance `row' beyond the last row of the window.

7362 positioning on the newline at EOL of R2L text within L2R
7363 paragraph, and vice versa.
7364 (try_cursor_movement): Check continued rows, in addition to
7365 continuation rows. Fixes unwarranted scroll when point enters a
7366 continued line of R2L text within an L2R paragraph, or vice versa.

7368 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
7369 from the end of a short line to the beginning of a continued line
7370 of R2L text within L2R paragraph.
7371 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for

7387 2011-08-22 Kenichi Handa <handa@m17n.org>
7389 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
7390 extra slot even if the purpose is char-code-property-table.
7392 2011-08-23 Eli Zaretskii <eliz@gnu.org>
7394 * xdisp.c (redisplay_window): When computing centering_position,
7395 account for the height of the header line. (Bug#8874)
7397 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
7398 instead of CHAR_TO_BYTE. Fixes a crash when a completion
7399 candidate is selected by the mouse, and that candidate has a
7400 composed character under the mouse.
7402 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
7403 coordinates reported by pos-visible-in-window-p for a composed
7404 character in column zero.

7414 composed buffer positions.
7416 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
7418 * image.c (gif_load): Don't assume that each subimage has the same
7419 dimensions as the base image. Handle disposal method that is
7420 "undefined" by the gif spec (Bug#9335).
7422 2011-08-20 Chong Yidong <cyd@stupidchicken.com>

7430 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
7431 from an Org mode buffer to a Speedbar frame.
7433 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
7434 a composition, take its buffer position from IT->cmp_it.charpos.
7435 Fixes cursor positioning at the beginning of a line that begins
7436 with a composed character.
7438 2011-08-18 Eli Zaretskii <eliz@gnu.org>
7440 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
7441 character bidirectional type, use STRONG_L instead. Fixes crashes
7442 in a buffer produced by `describe-categories'.
7444 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
7445 members before the level stack, so they would be saved and
7446 restored when copying iterator state. Fixes incorrect reordering
7447 around TABs covered by display properties.
7449 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>

7582 buffer/string position, to be restored by pop_it. Fix flags in
7583 the iterator structure wrt the object coming from a display
7584 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
7585 properties. (Bug#9284)

7796 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
7799 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
7801 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
7802 Without this fix, if a signal arrives just after memory fills up,
7803 'malloc' might be invoked reentrantly.
7805 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
7806 In other words, assume that every image size is allowed, on non-X
7807 hosts. This assumption is probably wrong, but it lets Emacs compile.
7809 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
7811 * regex.c (re_iswctype): Convert return values to boolean.
7813 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
7815 * xdisp.c (compute_display_string_pos): Don't use cached display
7816 string position if the buffer had its restriction changed.
7819 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
7821 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
7823 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
7825 Integer signedness and overflow and related fixes. (Bug#9079)
7827 * bidi.c: Integer size and overflow fixes.
7828 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
7829 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
7830 (bidi_cache_find_level_change, bidi_cache_ensure_space)
7831 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
7832 (bidi_find_other_level_edge):
7833 Use ptrdiff_t instead of EMACS_INT where either will do.
7834 This works better on 32-bit hosts configured --with-wide-int.
7835 (bidi_cache_ensure_space): Check for size-calculation overflow.
7836 Use % rather than repeated addition, for better worst-case speed.
7837 Don't set bidi_cache_size until after xrealloc returns, because it
7839 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
7840 (bidi_cache_ensure_space): Also check that the bidi cache size
7841 does not exceed that of the largest Lisp string or buffer. See Eli
7842 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
7844 * alloc.c (__malloc_size_t): Remove.
7845 All uses replaced by size_t. See Andreas Schwab's note
7846 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
7848 * image.c: Improve checking for integer overflow.
7849 (check_image_size): Assume that f is nonnull, since
7850 it is always nonnull in practice. This is one less thing to
7851 worry about when checking for integer overflow later.
7852 (x_check_image_size): New function, which checks for integer
7853 overflow issues inside X.
7854 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
7855 This removes the need for a memory_full check.
7856 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
7857 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
7858 (xbm_read_bitmap_data): Change locals back to 'int', since
7859 their values must fit in 'int'.
7860 (xpm_load_image, png_load, tiff_load):
7861 Invoke x_create_x_image_and_pixmap earlier,
7862 to avoid much needless work if the image is too large.
7863 (tiff_load): Treat overly large images as if
7864 x_create_x_image_and_pixmap failed, not as malloc failures.
7865 (gs_load): Use x_check_image_size.
7867 * gtkutil.c: Omit integer casts.
7868 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
7869 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
7871 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
7873 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
7874 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
7875 would wrongly return t on a 64-bit host.
7877 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
7878 The plain *_OVERFLOW macros run afoul of GCC bug 49705
7879 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
7880 and therefore cause GCC to emit a bogus diagnostic in some cases.
7882 * image.c: Integer signedness and overflow and related fixes.
7883 This is not an exhaustive set of fixes, but it's time to
7884 record what I've got.
7885 (lookup_pixel_color, check_image_size): Remove redundant decls.
7886 (check_image_size): Don't assume that arbitrary EMACS_INT values
7887 fit in 'int', or that arbitrary 'double' values fit in 'int'.
7888 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
7889 (tiff_load, imagemagick_load_image):
7890 Check for overflow in size calculations.
7891 (x_create_x_image_and_pixmap): Remove unnecessary test for
7892 xmalloc returning NULL; that can't happen.
7893 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
7894 (xpm_color_bucket): Use better integer hashing function.
7895 (xpm_cache_color): Don't possibly over-allocate memory.
7896 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
7897 (gif_memory_source):
7898 Use ptrdiff_t, not int or size_t, to record sizes.
7899 (png_load): Don't assume values greater than 2**31 fit in 'int'.
7900 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
7901 either works, as we prefer signed integers.
7902 (tiff_read_from_memory, tiff_write_from_memory):
7903 Return tsize_t, not size_t, since that's what the TIFF API wants.
7904 (tiff_read_from_memory): Don't fail simply because the read would
7905 go past EOF; instead, return a short read.
7906 (tiff_load): Omit no-longer-needed casts.
7907 (Fimagemagick_types): Don't assume size fits into 'int'.
7909 Improve hashing quality when configured --with-wide-int.
7910 * fns.c (hash_string): New function, taken from sxhash_string.
7911 Do not discard information about ASCII character case; this
7912 discarding is no longer needed.
7913 (sxhash-string): Use it. Change sig to match it. Caller changed.
7914 * lisp.h: Declare it.
7915 * lread.c (hash_string): Remove, since we now use fns.c's version.
7916 The fns.c version returns a wider integer if --with-wide-int is
7917 specified, so this should help the quality of the hashing a bit.
7919 * emacs.c: Integer overflow minor fix.
7920 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
7921 Define only if GNU_LINUX.
7922 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
7924 * dispnew.c: Integer signedness and overflow fixes.
7925 Remove unnecessary forward decls, that were a maintenance hassle.
7926 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
7928 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
7929 (scrolling_window): Use ptrdiff_t, not int, for byte count.
7930 (prepare_desired_row, line_draw_cost):
7931 Use int, not unsigned, where either works.
7932 (save_current_matrix, restore_current_matrix):
7933 Use ptrdiff_t, not size_t, where either works.
7934 (init_display): Check for overflow more accurately, and without
7935 relying on undefined behavior.
7937 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
7938 Remove, replacing with the new symbols in lisp.h. All uses changed.
7939 * fileio.c (make_temp_name):
7940 * filelock.c (lock_file_1, lock_file):
7941 * xdisp.c (message_dolog):
7942 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
7943 Use pMd etc. instead.
7944 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
7945 replacing the pWIDE etc. symbols removed from editfns.c.
7947 * keyboard.h (num_input_events): Now uintmax_t.
7948 This is (very slightly) less likely to mess up due to wraparound.
7951 * buffer.c: Integer signedness fixes.
7952 (alloc_buffer_text, enlarge_buffer_text):
7953 Use ptrdiff_t rather than size_t when either will do, as we prefer
7956 * alloc.c: Integer signedness and overflow fixes.
7957 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
7958 (__malloc_size_t): Default to size_t, not to int.
7959 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
7960 (Fgarbage_collect, mark_object_loop_halt, mark_object):
7961 Prefer ptrdiff_t to size_t when either would do, as we prefer
7963 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
7964 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
7965 Now const. Initialize with values that are in range even if char
7967 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
7968 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
7969 These functions do the right thing with sizes > 2**32.
7970 (check_depth): Now ptrdiff_t, not int.
7971 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
7972 Adjust to new way of storing sizes. Check for size overflow bugs
7974 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
7975 slightly wrong anyway, as it missed one instance of
7976 XMALLOC_OVERRUN_CHECK_OVERHEAD.
7977 (refill_memory_reserve): Omit needless cast to size_t.
7978 (mark_object_loop_halt): Mark as externally visible.
7980 * xselect.c: Integer signedness and overflow fixes.
7981 (Fx_register_dnd_atom, x_handle_dnd_message):
7982 Use ptrdiff_t, not size_t, since we prefer signed.
7983 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
7984 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
7985 x_dnd_atoms_size and x_dnd_atoms_length.
7987 * doprnt.c: Prefer signed to unsigned when either works.
7989 * doprnt.c (doprnt):
7991 * xdisp.c (vmessage):
7992 Use ptrdiff_t, not size_t, when using or implementing doprnt,
7993 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
7994 prefer signed arithmetic to avoid comparison confusion.
7995 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
7996 but is a bit tricky.
7998 Assume freestanding C89 headers, string.h, stdlib.h.
7999 * data.c, doprnt.c, floatfns.c, print.c:
8000 Include float.h unconditionally.
8001 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
8002 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
8003 * regex.c: Likewise for stddef.h, string.h.
8004 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
8005 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
8006 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
8007 (STDC_HEADERS): Remove obsolete defines.
8008 * sysdep.c: Include limits.h unconditionally.
8010 Assume support for memcmp, memcpy, memmove, memset.
8011 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
8012 * regex.c (memcmp, memcpy):
8013 Remove; we assume C89 now.
8015 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
8016 (__malloc_safe_bcopy): Remove; no longer needed.
8018 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
8019 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
8020 well either way, and we prefer signed to unsigned.
8022 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
8024 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
8025 closes the connection while we're reading (bug#9182).
8027 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
8029 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
8030 are specified (Bug#9168).
8032 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
8034 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
8035 Found by GCC static checking and --with-wide-int on a 32-bit host.
8037 2011-07-25 Eli Zaretskii <eliz@gnu.org>
8039 * xdisp.c (compute_display_string_pos): Fix logic of caching
8040 previous display string position. Initialize cached_prev_pos to
8041 -1. Fixes slow-down at the beginning of a buffer.
8043 2011-07-24 Eli Zaretskii <eliz@gnu.org>
8045 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
8046 for attrs[LFACE_FONTSET_INDEX].
8048 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
8050 * xml.c (parse_region): Remove unused local
8051 that was recently introduced.
8053 2011-07-23 Eli Zaretskii <eliz@gnu.org>
8055 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
8056 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
8058 * xdisp.c (move_it_in_display_line_to): Record the best matching
8059 position for TO_CHARPOS while scanning the line, and restore it on
8060 exit if none of the characters scanned was an exact match.
8061 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
8062 when exact match is impossible due to invisible text, and the
8063 lines are truncated.
8065 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
8067 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
8070 2011-07-22 Eli Zaretskii <eliz@gnu.org>
8072 Fix a significant slow-down of cursor motion with C-n, C-p,
8073 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
8074 auto-repeat under bidi redisplay in fontified buffers.
8075 * xdisp.c (compute_stop_pos_backwards): New function.
8076 (next_element_from_buffer): Call compute_stop_pos_backwards to
8077 find a suitable prev_stop when we find ourselves before
8079 (reseat): Don't look for prev_stop, as that could mean a very long
8081 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
8082 <cached_disp_overlay_modiff>: Cache for last found display string
8084 (compute_display_string_pos): Return the cached position if asked
8085 about the same buffer in the same area of character positions, and
8086 the buffer wasn't changed since the time the display string
8087 position was cached.
8089 2011-07-22 Eli Zaretskii <eliz@gnu.org>
8091 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
8092 is an integer, which is important for empty lines. (Bug#9149)
8094 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
8096 * frame.c (Fmodify_frame_parameters): In tty case, update the
8097 default face if necessary (Bug#4238).
8099 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
8101 * editfns.c (Fstring_to_char): No need to explain what a character
8102 is in the docstring (Bug#6576).
8104 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
8106 * xml.c (parse_region): Make sure we always return a tree.
8108 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
8110 * xml.c (parse_region): If a document contains only comments,
8113 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
8115 * xml.c (make_dom): Return comments, too.
8117 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
8120 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
8121 and the surrounding thread.
8122 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
8123 rather than fgets, and retry after EINTR. Otherwise, 'emacs
8124 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
8126 * s/openbsd.h (BROKEN_SIGIO): Define.
8127 * unexelf.c (unexec) [__OpenBSD__]:
8128 Don't update the .mdebug section of the Alpha COFF symbol table.
8130 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
8132 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
8135 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
8137 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
8138 This fixes some race conditions on the permissions of any newly
8141 * alloc.c (valid_pointer_p): Use pipe, not open.
8142 This fixes some permissions issues when debugging.
8144 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
8145 If fchown fails to set both uid and gid, try to set just gid,
8146 as that is sometimes allowed. Adjust the file's mode to eliminate
8147 setuid or setgid bits that are inappropriate if fchown fails.
8149 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
8151 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
8152 to compare Lisp_Objects.
8153 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
8154 global_gnutls_log_level, don't mistake it for a Lisp_Object.
8155 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
8157 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
8159 * lread.c (read_integer): Unread even EOF character.
8160 (read1): Likewise. Properly record start position of symbol.
8162 * lread.c (read1): Read `#:' as empty uninterned symbol if no
8163 symbol character follows.
8165 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
8167 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
8168 This works around a problem with the previous change to Fcopy_file.
8169 Recent glibc declares fchown with __attribute__((warn_unused_result)),
8170 and without this change, GCC might complain about discarding
8171 fchown's return value.
8173 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
8175 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
8177 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
8179 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
8181 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
8183 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
8184 it's used from the C level.
8186 * process.c: Use the same condition for POLL_FOR_INPUT in both
8187 keyboard.c and process.c (bug#1858).
8189 2011-07-09 Lawrence Mitchell <wence@gmx.li>
8191 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
8192 (Fgnutls_boot): Use it.
8194 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
8196 * doc.c (Fsubstitute_command_keys): Revert last change.
8198 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
8200 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
8201 quotes the next character, and doesn't affect other longer
8202 sequences (bug#8935).
8204 * lread.c (syms_of_lread): Clarify that is isn't only
8205 `eval-buffer' and `eval-defun' that's affected by
8206 `lexical-binding' (bug#8460).
8208 2011-07-15 Eli Zaretskii <eliz@gnu.org>
8210 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
8211 bidi redisplay when a line includes both an image and is truncated.
8213 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
8215 Fix minor problems found by static checking.
8216 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
8217 (elsz): Now a signed constant, not a size_t var. We prefer signed
8218 types to unsigned, to avoid integer comparison confusion. Without
8219 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
8220 "cannot optimize loop, the loop counter may overflow", a symptom
8222 * indent.c (Fvertical_motion): Mark locals as initialized.
8223 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
8225 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
8227 * search.c (Fre_search_backward): Mention `case-fold-search' in
8228 all the re_search_* functions (bug#8138).
8230 * keyboard.c (Fopen_dribble_file): Document when the file is
8233 2011-07-14 Eli Zaretskii <eliz@gnu.org>
8235 * bidi.c (bidi_dump_cached_states): Fix format of displaying
8238 Support bidi reordering of display and overlay strings.
8239 * xdisp.c (compute_display_string_pos)
8240 (compute_display_string_end): Accept additional argument STRING.
8241 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
8242 (reseat_to_string): Initialize bidi_it->string.s and
8243 bidi_it->string.schars.
8244 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
8245 NULL (avoids a crash in bidi_paragraph_init).
8246 Initialize itb.string.lstring.
8247 (init_iterator): Call bidi_init_it only of a valid
8248 buffer position was specified. Initialize paragraph_embedding to
8250 (reseat_to_string): Initialize the bidi iterator.
8251 (display_string): If we need to ignore text properties of
8252 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
8253 original value of -1 will not work with bidi.)
8254 (compute_display_string_pos): First arg is now struct

8747 (clone_per_buffer_values): Don't assume that

8788 Random fixes. E.g., (random) never returned negative values.
8789 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
8790 subseconds part to the entropy, as that's a bit more random.
8791 Prefer signed to unsigned, since the signedness doesn't matter and
8792 in general we prefer signed. When given a limit, use a
8793 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
8794 latter isn't right if USE_2_TAGS_FOR_INTS.
8795 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
8796 not 0..VALMASK. Don't discard "excess" bits that random () returns.

8808 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
8809 This is more efficient than Ffile_directory_p and avoids a minor race.
8811 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
8813 * buffer.c (Foverlay_put): Say what the return value is
8816 * fileio.c (barf_or_query_if_file_exists): Check first if the file
8817 is a directory before asking whether to use the file name
8819 (barf_or_query_if_file_exists): Make the "File is a directory"
8820 error be more correct.
8822 * fns.c (Frequire): Remove the mention of the .gz files, since
8823 that's installation-specific, but keep the mention of
8824 `get-load-suffixes'.
8826 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
8828 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

8839 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
8840 Also (re)move comments that are misplaced or no longer relevant.
8842 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
8844 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

8941 * eval.c (struct backtrace): Simplify and port the data structure.
8942 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
8943 signed bit field, as this assumption is not portable and it makes
8944 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
8945 "char debug_on_exit : 1" as this is not portable either; instead,
8946 use the portable "unsigned int debug_on_exit : 1". Remove unused
8947 member evalargs. Remove obsolete comments about cc bombing out.

9171 * dispnew.c (window_to_frame_vpos):
9172 * xfns.c (unwind_create_frame):
9173 * xterm.c (x_check_font): Remove unused local.
9174 * scroll.c (CHECK_BOUNDS):
9175 * xfaces.c (cache_fache): Rename local to avoid shadowing.
9176 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
9177 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
9178 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
9179 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
9181 (debug_method_add): Use va_list and vsprintf rather than relying
9182 on undefined behavior with wrong number of arguments.
9183 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
9184 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
9185 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
9186 since we're not interested in debugging glyphs with old libraries.
9187 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
9188 GCC 4.6.0's static checking.
9190 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
9192 Integer overflow and signedness fixes (Bug#8873).
9193 A few related buffer overrun fixes, too.
9195 * font.c (font_score): Use EMACS_INT, not int, to store XINT value.
9197 * dispextern.h (struct face.stipple):
9198 * image.c (x_bitmap_height, x_bitmap_width, x_bitmap_pixmap)
9199 (x_bitmap_mask, x_allocate_bitmap_record)
9200 (x_create_bitmap_from_data, x_create_bitmap_from_file)
9201 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
9202 (x_create_bitmap_from_xpm_data):
9203 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
9204 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
9206 * xfaces.c (load_pixmap):
9207 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
9208 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
9209 (.bitmaps_last, struct x_output.icon_bitmap):
9210 Use ptrdiff_t, not int, for bitmap indexes.
9211 (x_allocate_bitmap_record): Check for size overflow.
9212 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
9214 Use ptrdiff_t, not int, for overlay counts.
9215 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
9216 * editfns.c (overlays_around, get_pos_property):
9217 * textprop.c (get_char_property_and_overlay):
9218 * xdisp.c (next_overlay_change, note_mouse_highlight):
9219 * xfaces.c (face_at_buffer_position):
9220 * buffer.c (OVERLAY_COUNT_MAX): New macro.
9221 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
9222 (Fnext_overlay_change, Fprevious_overlay_change)
9223 (mouse_face_overlay_overlaps, Foverlays_in):
9224 Use ptrdiff_t, not int, for sizes.
9225 (overlays_at, overlays_in): Check for size-calculation overflow.
9227 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
9229 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
9230 (x_session_initialize): Do not assume string length fits in int.
9232 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
9233 This is unlikely, but can occur if DPI is outlandish.
9235 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
9236 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
9238 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
9239 * xrdb.c (magic_file_p, search_magic_path):
9240 Omit last arg SUFFIX; it was always 0. All callers changed.
9241 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
9243 * xfont.c (xfont_match): Avoid need for strlen.
9245 * xfns.c: Don't assume strlen fits in int.
9246 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
9248 * xdisp.c (message_log_check_duplicate): Return intmax_t,
9249 not unsigned long, as we prefer signed integers. All callers changed.
9250 Detect integer overflow in repeat count.
9251 (message_dolog): Don't assume print length fits in 39 bytes.
9252 (display_mode_element): Don't assume strlen fits in int.
9254 * termcap.c: Don't assume sizes fit in int and never overflow.
9255 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
9256 (gobble_line): Check for size-calculation overflow.
9258 * minibuf.c (Fread_buffer):
9259 * lread.c (intern, intern_c_string):
9260 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
9261 Don't assume string length fits in int.
9263 * keyboard.c (parse_tool_bar_item):
9264 * gtkutil.c (style_changed_cb): Avoid need for strlen.
9266 * font.c: Don't assume string length fits in int.
9267 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
9268 Use ptrdiff_t, not int.
9269 (font_intern_prop): Don't assume string length fits in int.
9270 Don't assume integer property fits in fixnum.
9271 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
9273 * filelock.c: Fix some buffer overrun and integer overflow issues.
9274 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
9275 Reformulate so as not to need the command string.
9276 Invoke gzip -cd rather than gunzip, as it's more portable.
9277 (lock_info_type, lock_file_1, lock_file):
9278 Don't assume pid_t and time_t fit in unsigned long.
9279 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
9280 (current_lock_owner): Prefer signed type for sizes.
9281 Use memcpy, not strncpy, where memcpy is what is really wanted.
9282 Don't assume (via atoi) that time_t and pid_t fit in int.
9283 Check for time_t and/or pid_t out of range, e.g., via a network share.
9284 Don't alloca where an auto var works fine.
9286 * fileio.c: Fix some integer overflow issues.
9287 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
9288 Don't assume string length fits in int.
9289 (directory_file_name): Don't assume string length fits in long.
9290 (make_temp_name): Don't assume pid fits in int, or that its print
9291 length is less than 20.
9293 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
9295 * coding.c (make_subsidiaries): Don't assume string length fits in int.
9297 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
9299 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
9300 We prefer signed integers, even for size calculations.
9302 * emacs.c: Don't assume string length fits in 'int'.
9303 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
9304 (main): Don't invoke strlen when not needed.
9306 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
9307 (XD_DEBUG_MESSAGE): Don't waste a byte.
9309 * callproc.c (getenv_internal_1, getenv_internal)
9311 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
9313 * lread.c (invalid_syntax): Omit length argument.
9314 All uses changed. This doesn't fix a bug, but it simplifies the
9315 code away from its former Hollerith-constant appearance, and it's
9316 one less 'int' to worry about when looking at integer-overflow issues.
9317 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
9319 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
9320 This didn't break anything, but it didn't help either.
9321 It's confusing to put a bogus integer in a place where the actual
9322 value does not matter.
9323 (LIST_END_P): Remove unused macro and its bogus comment.
9324 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
9326 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
9327 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
9329 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
9330 We prefer signed types, and the value cannot exceed the EMACS_INT
9331 range anyway (because otherwise the length would not be representable).
9332 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
9333 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
9334 This avoids a GCC warning when WIDE_EMACS_INT.
9336 * indent.c (sane_tab_width): New function.
9337 (current_column, scan_for_column, Findent_to, position_indentation)
9338 (compute_motion): Use it. This is just for clarity.
9339 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
9341 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
9343 * lisp.h (lint_assume): New macro.
9344 * composite.c (composition_gstring_put_cache):
9345 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
9347 * editfns.c, insdel.c:
9348 Omit unnecessary forward decls, to simplify future changes.
9350 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
9352 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
9354 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
9355 Use much-faster test for byte-length change.
9356 Don't assume string byte-length fits in 'int'.
9357 Check that character arg fits in 'int'.
9358 (mapcar1): Declare byte as byte, for clarity.
9360 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
9362 * fns.c (concat): Catch string overflow earlier.
9363 Do not rely on integer wraparound.
9365 * dispextern.h (struct it.overlay_strings_charpos)
9366 (struct it.selective): Now EMACS_INT, not int.
9367 * xdisp.c (forward_to_next_line_start)
9368 (back_to_previous_visible_line_start)
9369 (reseat_at_next_visible_line_start, next_element_from_buffer):
9370 Don't arbitrarily truncate the value of 'selective' to int.
9372 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
9374 * composite.c: Don't truncate sizes to 'int'.
9375 (composition_gstring_p, composition_reseat_it)
9376 (composition_adjust_point): Use EMACS_INT, not int.
9377 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
9378 not EMACS_UINT, for indexes.
9380 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
9382 * buffer.c: Include <verify.h>.
9383 (struct sortvec.priority, struct sortstr.priority):
9384 Now EMACS_INT, not int.
9385 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
9386 (struct sortstr.size, record_overlay_string)
9387 (struct sortstrlist.size, struct sortlist.used):
9388 Don't truncate size to int.
9389 (record_overlay_string): Check for size-calculation overflow.
9390 (init_buffer_once): Check at compile-time, not run-time.
9392 2011-06-22 Jim Meyering <meyering@redhat.com>
9394 Don't leak an XBM-image-sized buffer
9395 * image.c (xbm_load): Free the image buffer after using it.
9397 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
9400 * composite.c (find_automatic_composition): Omit needless 'return 0;'
9401 that Sun C diagnosed.
9402 * fns.c (secure_hash): Fix pointer signedness issue.
9403 * intervals.c (static_offset_intervals): New function.
9404 (offset_intervals): Use it.
9406 2011-06-21 Leo Liu <sdl.web@gmail.com>
9409 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
9412 * fns.c (secure_hash): Rename from crypto_hash_function and change
9413 the first arg to accept symbols.
9414 (Fsecure_hash): New primitive.
9415 (syms_of_fns): New symbols.
9417 2011-06-20 Deniz Dogan <deniz@dogan.se>
9419 * process.c (Fset_process_buffer): Clarify return value in
9422 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
9424 * dispnew.c (add_window_display_history): Use BVAR.
9426 * xdisp.c (debug_method_add): Use BVAR.
9427 (check_window_end, dump_glyph_matrix, dump_glyph)
9428 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
9430 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
9433 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
9434 check till after the cache is created in init_frame_faces.
9436 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
9438 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
9440 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
9442 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
9443 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
9444 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
9446 Improve buffer-overflow checking (Bug#8873).
9447 * fileio.c (Finsert_file_contents):
9448 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
9449 Remove the old (too-loose) buffer overflow checks.
9450 They weren't needed, since make_gap checks for buffer overflow.
9451 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
9452 The old code merely checked for Emacs fixnum overflow, and relied
9453 on undefined (wraparound) behavior. The new code avoids undefined
9454 behavior, and also checks for ptrdiff_t and/or size_t overflow.
9456 * editfns.c (Finsert_char): Don't dump core with very negative counts.
9457 Tune. Don't use wider integers than needed. Don't use alloca.
9458 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
9460 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
9462 * insdel.c, lisp.h (buffer_overflow): New function.
9463 (insert_from_buffer_1, replace_range, replace_range_2):
9464 * insdel.c (make_gap_larger):
9465 * editfns.c (Finsert_char):
9466 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
9468 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
9470 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
9472 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
9474 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
9475 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
9477 * fileio.c: Don't assume EMACS_INT fits in off_t.
9478 (emacs_lseek): New static function.
9479 (Finsert_file_contents, Fwrite_region): Use it.
9480 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
9482 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
9484 * fns.c: Don't overflow int when computing a list length.
9485 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
9486 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
9487 truncation on 64-bit hosts. Check for QUIT every
9488 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
9489 faster and is responsive enough.
9490 (Flength): Report an error instead of overflowing an integer.
9491 (Fsafe_length): Return a float if the value is not representable
9492 as a fixnum. This shouldn't happen except in contrived situations.
9493 (Fnthcdr, Fsort): Don't assume list length fits in int.
9494 (Fcopy_sequence): Don't assume vector length fits in int.
9496 * alloc.c: Check that resized vectors' lengths fit in fixnums.
9497 (header_size, word_size): New constants.
9498 (allocate_vectorlike): Don't check size overflow here.
9499 (allocate_vector): Check it here instead, since this is the only
9500 caller of allocate_vectorlike that could cause overflow.
9501 Check that the new vector's length is representable as a fixnum.
9503 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
9504 The previous code was bogus. For example, next_almost_prime (32)
9505 returned 39, which is undesirable as it is a multiple of 3; and
9506 next_almost_prime (24) returned 25, which is a multiple of 5 so
9507 why was the code bothering to check for multiples of 7?
9509 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
9511 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
9513 Variadic C functions now count arguments with ptrdiff_t.
9514 This partly undoes my 2011-03-30 change, which replaced int with size_t.
9515 Back then I didn't know that the Emacs coding style prefers signed int.
9516 Also, in the meantime I found a few more instances where arguments
9517 were being counted with int, which may truncate counts on 64-bit
9518 machines, or EMACS_INT, which may be unnecessarily wide.
9519 * lisp.h (struct Lisp_Subr.function.aMANY)
9520 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
9521 Arg counts are now ptrdiff_t, not size_t.
9522 All variadic functions and their callers changed accordingly.
9523 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
9524 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
9525 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
9526 * callint.c (Fcall_interactively): Check arg count for overflow,
9527 to avoid potential buffer overrun. Use signed char, not 'int',
9528 for 'varies' array, so that we needn't bother to check its size
9529 calculation for overflow.
9530 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
9531 * eval.c (apply_lambda):
9532 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
9533 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
9534 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
9536 * callint.c (Fcall_interactively): Don't use index var as event count.
9538 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
9539 * mem-limits.h (SIZE): Remove; no longer used.
9541 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
9543 Remove unnecessary casts.
9544 * xterm.c (x_term_init):
9545 * xfns.c (x_set_border_pixel):
9546 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
9547 These aren't needed now that we assume ANSI C.
9549 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
9550 It's more likely to cause problems (due to unsigned overflow)
9553 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
9555 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
9557 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
9559 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
9561 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
9563 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
9565 GLYPH_CODE_FACE returns EMACS_INT, not int.
9566 * dispextern.h (merge_faces):
9567 * xfaces.c (merge_faces):
9568 * xdisp.c (get_next_display_element, next_element_from_display_vector):
9569 Don't assume EMACS_INT fits in int.
9571 * character.h (CHAR_VALID_P): Remove unused parameter.
9572 * fontset.c, lisp.h, xdisp.c: All uses changed.
9574 * editfns.c (Ftranslate_region_internal): Omit redundant test.
9576 * fns.c (concat): Minor tuning based on overflow analysis.
9577 This doesn't fix any bugs. Use int to hold character, instead
9578 of constantly refetching from Emacs object. Use XFASTINT, not
9579 XINT, for value known to be a character. Don't bother comparing
9580 a single byte to 0400, as it's always less.
9582 * floatfns.c (Fexpt):
9583 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
9585 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
9588 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
9590 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
9591 Without this fix, on a 64-bit host (aset S 0 4294967386) would
9592 incorrectly succeed when S was a string, because 4294967386 was
9593 truncated before it was used.
9595 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
9596 Otherwise, an out-of-range integer could cause undefined behavior
9599 * composite.c: Use int, not EMACS_INT, for characters.
9600 (fill_gstring_body, composition_compute_stop_pos): Use int, not
9601 EMACS_INT, for values that are known to be in character range.
9602 This doesn't fix any bugs but is the usual style inside Emacs and
9603 may generate better code on 32-bit machines.
9605 Make sure a 64-bit char is never passed to ENCODE_CHAR.
9606 This is for reasons similar to the recent CHAR_STRING fix.
9607 * charset.c (Fencode_char): Check that character arg is actually
9608 a character. Pass an int to ENCODE_CHAR.
9609 * charset.h (ENCODE_CHAR): Verify that the character argument is no
9610 wider than 'int', as a compile-time check to prevent future regressions
9613 * character.c (char_string): Remove unnecessary casts.
9615 Make sure a 64-bit char is never passed to CHAR_STRING.
9616 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
9617 by silently ignoring the top 32 bits, allowing some values
9618 that were far too large to be valid characters.
9619 * character.h: Include <verify.h>.
9620 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
9621 arguments are no wider than unsigned, as a compile-time check
9622 to prevent future regressions in this area.
9624 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
9625 (Fsubst_char_in_region):
9627 * xdisp.c (decode_mode_spec_coding):
9628 Adjust to CHAR_STRING's new requirement.
9629 * editfns.c (Finsert_char, Fsubst_char_in_region):
9630 * fns.c (concat): Check that character args are actually
9631 characters. Without this test, these functions did the wrong
9632 thing with wildly out-of-range values on 64-bit hosts.
9634 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
9635 These casts should not be needed on 32-bit hosts, either.
9636 * keyboard.c (read_char):
9637 * lread.c (Fload): Remove casts to unsigned.
9639 * lisp.h (UNSIGNED_CMP): New macro.
9640 This fixes comparison bugs on 64-bit hosts.
9641 (ASCII_CHAR_P): Use it.
9642 * casefiddle.c (casify_object):
9643 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
9644 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
9645 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
9646 * dispextern.h (FACE_FROM_ID):
9647 * keyboard.c (read_char): Use UNSIGNED_CMP.
9649 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
9650 not to EMACS_INT, to avoid GCC warning.
9652 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
9654 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
9655 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
9656 isn't needed on 32-bit machines.
9658 * buffer.c (Fgenerate_new_buffer_name):
9659 Use EMACS_INT for count, not int.
9660 (advance_to_char_boundary): Return EMACS_INT, not int.

9672 (mark_object): Use ptrdiff_t, not int.
9673 * lisp.h (pD): New macro.
9674 * print.c (print_object): Use it.
9676 * alloc.c: Use EMACS_INT, not int, to count objects.

9678 (total_free_conses, total_free_markers, total_free_symbols)
9679 (total_free_floats, total_floats, total_free_intervals)
9680 (total_intervals, total_strings, total_free_strings):
9681 Now EMACS_INT, not int. All uses changed.
9682 (Fgarbage_collect): Compute overall total using a double, so that
9683 integer overflow is less likely to be a problem. Check for overflow
9684 when converting back to an integer.
9685 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
9686 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
9687 These were 'int' variables that could overflow on 64-bit hosts;
9688 they were never used, so remove them instead of repairing them.
9689 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
9690 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
9691 Previously, this ceilinged at INT_MAX, but that doesn't work on
9693 (allocate_pseudovector): Don't use EMACS_INT when int would do.
9695 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
9696 (allocate_vectorlike): Check for ptrdiff_t overflow.
9697 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
9698 when a (possibly-narrower) signed value would do just as well.
9699 We prefer using signed arithmetic, to avoid comparison confusion.
9701 * alloc.c: Catch some string size overflows that we were missing.
9702 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
9703 for convenience in STRING_BYTES_MAX.
9704 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
9705 The definition here is exact; the one in lisp.h was approximate.
9706 (allocate_string_data): Check for string overflow. This catches
9707 some instances we weren't catching before. Also, it catches
9708 size_t overflow on (unusual) hosts where SIZE_MAX <= min
9709 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
9710 and ptrdiff_t and EMACS_INT are both 64 bits.
9712 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
9713 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
9714 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
9716 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
9718 * alloc.c (Fmake_string): Check for out-of-range init.

9735 Call gtk_window_set_resizable if HAVE_GTK3.
9736 (x_wm_set_size_hint): Call emacs_fixed_set_min_size with min width
9737 and height if HAVE_GTK3 (Bug#8505).

10291 instead of using explicit *_CHAR codes.
10292 (bidi_resolve_explicit, bidi_resolve_weak):

10301 (bidi_level_of_next_char): Don't try to lookup the cache for the
10302 next/previous character if nothing is cached there yet, or if we
10303 were just reseat()'ed to a new position.
10305 * xdisp.c (set_cursor_from_row): Set start and stop points
10306 according to the row's direction when priming the loop that looks
10307 for the glyph on which to display cursor.

10309 (display_prop_intangible_p): Reimplement to call
10310 handle_display_spec instead of single_display_spec_intangible_p.
10311 Accept 3 additional arguments needed by handle_display_spec.
10312 This fixes incorrect cursor motion across display property with complex

10321 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
10322 value of a `display' property is a "replacing spec".
10323 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
10324 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
10325 the display property, but just return a value indicating whether
10326 the display property will replace the characters it covers.
10327 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
10328 frame_window_p members of struct bidi_it.

10354 * gnutls.c: Use Emacs's memory allocators.
10355 Without this change, the gnutls library would invoke malloc etc.
10356 directly, which causes problems on non-SYNC_INPUT hosts, and which
10357 runs afoul of improving memory_full behavior. (Bug#8761)
10358 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
10359 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
10360 xfree instead of the default malloc, realloc, free.
10361 (Fgnutls_boot): No need to check for memory allocation failure,
10362 since xmalloc does that for us.

10385 for hashes and hash indexes, instead of 'unsigned' and 'int'.
10386 * alloc.c (allocate_vectorlike):
10387 Check for overflow in vector size calculations.
10388 * ccl.c (ccl_driver):
10389 Check for overflow when converting EMACS_INT to int.

10391 need to be updated by these changes.
10392 * fns.c (make_hash_table, maybe_resize_hash_table):
10393 Check for integer overflow with large hash tables.
10394 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
10395 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
10396 (SXHASH_REDUCE): New macro.
10397 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
10398 Use it instead of discarding useful hash info with large hash values.
10399 (sxhash_float): New function.
10400 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
10401 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
10402 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
10403 Rewrite to use FIXNUM_BITS, as this simplifies things.
10404 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
10405 Adjust signatures to match updated version of code.
10406 (consing_since_gc): Now EMACS_INT, since a single hash table can
10407 use more than INT_MAX bytes.

10456 Make it possible to run ./temacs.
10458 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
10459 syms_of_callproc does the same thing. Remove test for

10514 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
10515 exiting (Bug#8239).
10517 2011-05-28 Jim Meyering <meyering@redhat.com>
10519 Avoid a sign-extension bug in crypto_hash_function.
10520 * fns.c (to_uchar): Define.
10521 (crypto_hash_function): Use it to convert some newly-signed
10522 variables to unsigned, to avoid sign-extension bugs. For example,
10523 without this change, (md5 "truc") would evaluate to
10524 45723a2aff78ff4fff7fff1114760e62 rather than the expected
10525 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
10526 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
10528 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
10530 Integer overflow fixes.
10532 * dbusbind.c: Serial number integer overflow fixes.
10533 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
10534 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
10535 to hold a serial number that is too large for a fixnum.
10536 (Fdbus_method_return_internal, Fdbus_method_error_internal):
10537 Check for serial numbers out of range. Decode any serial number
10538 that was so large that it became a float. (Bug#8722)
10540 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
10541 (Fdbus_call_method, Fdbus_call_method_asynchronously):
10542 Use XFASTINT rather than XUINT when numbers are nonnegative.
10543 (xd_append_arg, Fdbus_method_return_internal):
10544 (Fdbus_method_error_internal): Likewise. Also, for unsigned
10545 arguments, check that Lisp number is nonnegative, rather than
10546 silently wrapping negative numbers around. (Bug#8722)
10547 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
10550 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
10552 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
10554 ccl: Add integer overflow checks.
10555 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
10556 (IN_INT_RANGE): New macros.
10557 (ccl_driver): Use them to check for integer overflow when
10558 decoding a CCL program. Many of the new checks are whether XINT (x)
10559 fits in int; it doesn't always, on 64-bit hosts. The new version
10560 doesn't catch all possible integer overflows, but it's an
10561 improvement. (Bug#8719)
10563 * alloc.c (make_event_array): Use XINT, not XUINT.
10564 There's no need for unsigned here.
10566 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
10567 This follows up to the 2011-05-06 change that substituted uintptr_t
10568 for EMACS_INT. This case wasn't caught back then.
10570 Rework Fformat to avoid integer overflow issues.
10571 * editfns.c: Include <float.h> unconditionally, as it's everywhere
10572 now (part of C89). Include <verify.h>.
10573 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
10574 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
10575 (Fformat): Avoid the prepass trying to compute sizes; it was only
10576 approximate and thus did not catch overflow reliably. Instead, walk
10577 through the format just once, formatting and computing sizes as we go,
10578 checking for integer overflow at every step, and allocating a larger
10579 buffer as needed. Keep track separately whether the format is
10580 multibyte. Keep only the most-recently calculated precision, rather
10581 than them all. Record whether each argument has been converted to
10582 string. Use EMACS_INT, not int, for byte and char and arg counts.
10583 Support field widths and precisions larger than INT_MAX. Avoid
10584 sprintf's undefined behavior with conversion specifications such as %#d
10585 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
10586 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
10587 formatting out-of-range floating point numbers with int
10588 formats. (Bug#8668)
10590 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
10592 * data.c: Avoid integer truncation in expressions involving floats.
10593 * data.c: Include <intprops.h>.
10594 (arith_driver): When there's an integer overflow in an expression
10595 involving floating point, convert the integers to floating point
10596 so that the resulting value does not suffer from catastrophic
10597 integer truncation. For example, on a 64-bit host (* 4
10598 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
10599 Do not rely on undefined behavior after integer overflow.
10601 merge count_size_as_multibyte, parse_str_to_multibyte
10602 * character.c, character.h (count_size_as_multibyte):
10603 Rename from parse_str_to_multibyte; all uses changed.
10604 Check for integer overflow.
10605 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
10606 since it's now a duplicate of the other. This is more of
10607 a character than a buffer op, so better that it's in character.c.
10608 * fns.c, print.c: Adjust to above changes.
10610 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
10612 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
10614 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
10616 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
10617 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
10618 (x_clipboard_manager_save): Now static.
10619 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
10621 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
10622 (crypto_hash_function): Now static.
10623 Fix pointer signedness problems. Avoid unnecessary initializations.
10625 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
10627 * termhooks.h (Vselection_alist): Make it terminal-local.
10629 * terminal.c (create_terminal): Initialize it.
10631 * xselect.c: Support for clipboard managers.
10632 (Vselection_alist): Move to termhooks.h as terminal-local var.
10633 (LOCAL_SELECTION): New macro.
10634 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
10635 (symbol_to_x_atom): Remove gratuitous arg.
10636 (x_handle_selection_request, lisp_data_to_selection_data)
10637 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
10638 (x_own_selection, x_get_local_selection, x_convert_selection):
10639 New arg, specifying work frame. Use terminal-local Vselection_alist.
10640 (some_frame_on_display): Delete unused function.
10641 (Fx_own_selection_internal, Fx_get_selection_internal)
10642 (Fx_disown_selection_internal, Fx_selection_owner_p)
10643 (Fx_selection_exists_p): New optional frame arg.
10644 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
10645 (x_handle_selection_clear): Don't treat other terminals with the
10646 same keyboard specially. Use the terminal-local Vselection_alist.
10647 (x_clear_frame_selections): Use Frun_hook_with_args.
10649 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
10651 * xterm.h: Add support for those atoms.
10653 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
10655 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
10656 (converted_selections, conversion_fail_tag): New global variables.
10657 (x_selection_request_lisp_error): Free the above.
10658 (x_get_local_selection): Remove unnecessary code.
10659 (x_reply_selection_request): Args changed; handle arbitrary array
10660 of converted selections stored in converted_selections.
10661 Separate the XChangeProperty and SelectionNotify steps.
10662 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
10663 (x_convert_selection): New function.
10664 (x_handle_selection_event): Simplify.
10665 (x_get_foreign_selection): Don't ignore incoming requests while
10666 waiting for an answer; this will fail when we implement
10667 SAVE_TARGETS, and seems unnecessary anyway.
10668 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
10669 (Vx_sent_selection_functions): Doc fix.
10671 2011-05-26 Leo Liu <sdl.web@gmail.com>
10673 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
10675 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10677 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
10679 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
10680 for fringe update if it has periodic bitmap.
10681 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
10682 and fringe_bitmap_periodic_p.
10684 * fringe.c (get_fringe_bitmap_data): New function.
10685 (draw_fringe_bitmap_1, update_window_fringes): Use it.
10686 (update_window_fringes): Record periodicity of fringe bitmap in glyph
10687 row. Mark glyph row for fringe update if periodicity changed.
10689 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
10690 for fringe update unless it has periodic bitmap.
10692 2011-05-25 Kenichi Handa <handa@m17n.org>
10694 * xdisp.c (get_next_display_element): Set correct it->face_id for
10695 a static composition.
10697 2011-05-24 Leo Liu <sdl.web@gmail.com>
10700 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
10702 * fns.c (crypto_hash_function, Fsha1): New function.
10703 (Fmd5): Use crypto_hash_function.
10704 (syms_of_fns): Add Ssha1.
10706 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
10708 * gnutls.c: Remove unused macros.
10709 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
10710 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
10711 Remove macros that are defined and never used.
10712 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
10714 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
10716 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
10717 (Fx_get_selection_internal): Minor cleanup.
10718 (Fx_own_selection_internal): Rename arguments for consistency with
10721 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
10723 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
10725 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
10727 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
10729 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10731 * dispnew.c (scrolling_window): Don't exclude the case that the
10732 last enabled row in the desired matrix touches the bottom boundary.
10734 2011-05-21 Glenn Morris <rgm@gnu.org>
10736 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
10737 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
10738 and add some more files.
10740 2011-05-20 Eli Zaretskii <eliz@gnu.org>
10742 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
10743 report_file_error introduced by the change from 2011-05-07.
10745 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
10747 * systime.h (Time): Define only if emacs is defined.
10748 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
10749 where the include path doesn't have X11/X.h by default. See
10750 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
10752 2011-05-20 Kenichi Handa <handa@m17n.org>
10754 * composite.c (find_automatic_composition): Fix previous change.
10756 2011-05-20 Glenn Morris <rgm@gnu.org>
10758 * lisp.mk: New file, split from Makefile.in.
10759 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
10760 (shortlisp): Remove.
10761 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
10763 2011-05-19 Glenn Morris <rgm@gnu.org>
10765 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
10766 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
10767 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
10768 (lisp): Set the order to that of loadup.el.
10769 (shortlisp): Make it a copy of $lisp.
10770 (SOME_MACHINE_LISP): Remove.
10771 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
10772 Use just $shortlisp, not $SOME_MACHINE_LISP too.
10774 2011-05-18 Kenichi Handa <handa@m17n.org>
10776 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
10777 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
10778 (find_automatic_composition): Mostly rewrite for efficiency.
10780 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
10782 * makefile.w32-in: Update dependencies.
10784 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
10786 * menu.c: Include limits.h (fixes the MS-Windows build broken by
10787 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
10789 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
10791 Fix some integer overflow issues, such as string length overflow.
10793 * insdel.c (count_size_as_multibyte): Check for string overflow.
10795 * character.c (lisp_string_width): Check for string overflow.
10796 Use EMACS_INT, not int, for string indexes and lengths; in
10797 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
10798 the resulting string length overflows an EMACS_INT; instead,
10799 report a string overflow if no precision given. When checking for
10800 precision exhaustion, use a check that cannot possibly have
10801 integer overflow. (Bug#8675)
10802 * character.h (lisp_string_width): Adjust to new signature.
10804 * alloc.c (string_overflow): New function.
10805 (Fmake_string): Use it. This doesn't change behavior, but saves
10806 a few bytes and will simplify future changes.
10807 * character.c (string_escape_byte8): Likewise.
10808 * lisp.h (string_overflow): New decl.
10810 Fixups, following up to the user-interface timestamp change.
10811 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
10812 for UI timestamps, instead of unsigned long.
10813 * msdos.c (mouse_get_pos): Likewise.
10814 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
10815 * w32gui.h (Time): Define by including "systime.h" rather than by
10816 declaring it ourselves. (Bug#8664)
10818 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
10819 * image.c (clear_image_cache): Likewise.
10821 * term.c (term_mouse_position): Don't assume time_t wraparound.
10823 Be more systematic about user-interface timestamps.
10824 Before, the code sometimes used 'Time', sometimes 'unsigned long',
10825 and sometimes 'EMACS_UINT', to represent these timestamps.
10826 This change causes it to use 'Time' uniformly, as that's what X uses.
10827 This makes the code easier to follow, and makes it easier to catch
10828 integer overflow bugs such as Bug#8664.
10829 * frame.c (Fmouse_position, Fmouse_pixel_position):
10830 Use Time, not unsigned long, for user-interface timestamps.
10831 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
10832 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
10833 * keyboard.h (last_event_timestamp): Likewise.
10834 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
10835 * menu.h (xmenu_show): Likewise.
10836 * term.c (term_mouse_position): Likewise.
10837 * termhooks.h (struct input_event.timestamp): Likewise.
10838 (struct terminal.mouse_position_hook): Likewise.
10839 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
10840 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
10841 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
10842 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
10843 what it was before.
10844 * menu.h, termhooks.h: Include "systime.h", for Time.
10846 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
10847 Don't assume that the difference between two unsigned long values
10848 can fit into an integer. At this point, we know button_down_time
10849 <= event->timestamp, so the difference must be nonnegative, so
10850 there's no need to cast the result if double-click-time is
10851 nonnegative, as it should be; check that it's nonnegative, just in
10852 case. This bug is triggered when events are more than 2**31 ms
10853 apart (about 25 days). (Bug#8664)
10855 * xselect.c (last_event_timestamp): Remove duplicate decl.
10856 (x_own_selection): Remove needless cast to unsigned long.
10858 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
10859 that always fit in int. Use a sentinel instead of a counter, to
10860 avoid a temp and to allay GCC's concerns about possible int overflow.
10861 * frame.h (struct frame): Use int for menu_bar_items_used
10862 instead of EMACS_INT, since it always fits in int.
10864 * menu.c (grow_menu_items): Check for int overflow.
10866 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
10868 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
10869 Before, the code was not consistent. These values cannot exceed
10870 2**31 - 1 so there's no need to make them unsigned.
10871 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
10872 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
10873 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
10875 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
10877 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
10878 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
10879 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
10880 presumably because the widths might not match.
10882 * window.c (size_window): Avoid needless test at loop start.
10884 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
10886 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
10888 2011-05-12 Drew Adams <drew.adams@oracle.com>
10890 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
10892 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10894 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
10895 `width' to `bar_area_x' and `bar_area_width', respectively.
10896 (x_scroll_run): Take account of fringe background extension.
10898 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
10899 Rename local vars `left' and `width' to `bar_area_x' and
10900 `bar_area_width', respectively.
10901 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
10902 background extension.
10904 2011-05-10 Jim Meyering <meyering@redhat.com>
10906 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
10908 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
10910 * image.c (Finit_image_library): Return t for built-in image types,
10911 like pbm and xbm. (Bug#8640)
10913 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
10915 * w32menu.c (set_frame_menubar): Fix submenu allocation.
10917 2011-05-07 Eli Zaretskii <eliz@gnu.org>
10919 * w32console.c (Fset_screen_color): Doc fix.
10920 (Fget_screen_color): New function.
10921 (syms_of_ntterm): Defsubr it.
10923 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
10924 unlink the temporary file if Fcall_process didn't create it in the
10926 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
10927 child process will be redirected to a file specified with `:file'.
10928 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
10929 cue to call_process_cleanup not to close that handle.
10931 2011-05-07 Ben Key <bkey76@gmail.com>
10933 * makefile.w32-in: The bootstrap-temacs rule now makes use of
10934 one of two shell specific rules, either bootstrap-temacs-CMD or
10935 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
10936 to the previous implementation of the bootstrap-temacs rule.
10937 The bootstrap-temacs-CMD rule is similar to the previous
10938 implementation of the bootstrap-temacs rule except that it
10939 makes use of the ESC_CFLAGS variable instead of the CFLAGS
10942 These changes, along with some changes to nt/configure.bat,
10943 nt/gmake.defs, and nt/nmake.defs, are required to extend my
10944 earlier fix to add support for --cflags and --ldflags options
10945 that include quotes so that it works whether make uses cmd or
10948 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
10950 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
10951 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
10953 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
10954 a string. Handle both cases.
10955 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
10956 (Fdbus_register_method): Use Qinvalid_function.
10958 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
10960 * makefile.w32-in: Update dependencies.
10961 (LISP_H): Add inttypes.h and stdin.h.
10962 (PROCESS_H): Add unistd.h.
10964 2011-05-06 Eli Zaretskii <eliz@gnu.org>
10966 * lread.c: Include limits.h (fixes the MS-Windows build broken by
10967 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
10969 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
10971 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
10973 * term.c (vfatal): Remove stray call to va_end.
10974 It's not needed and the C Standard doesn't allow it here anyway.
10976 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
10977 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
10979 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
10982 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
10984 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
10986 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
10988 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
10990 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
10992 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
10993 * charset.c (Fdefine_charset_internal): Don't initialize
10994 charset.code_space[15]. The value was garbage, on hosts with
10995 32-bit int (Bug#8600).
10997 * lread.c (read_integer): Be more consistent with string-to-number.
10998 Use string_to_number to do the actual conversion; this avoids
10999 rounding errors and fixes some other screwups. Without this fix,
11000 for example, #x1fffffffffffffff was misread as -2305843009213693952.
11001 (digit_to_number): Move earlier, for benefit of read_integer.
11002 Return -1 if the digit is out of range for the base, -2 if it is
11003 not a digit in any supported base. (Bug#8602)
11005 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
11007 * dispnew.c (scrolling_window): Return 1 if we scrolled,
11008 to match comment at start of function. This also removes a
11009 GCC warning about overflow in a 32+64-bit port.
11011 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
11013 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
11014 Reported by Stefan Monnier in
11015 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
11016 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
11017 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
11019 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
11020 (EMACS_UINTPTR): Likewise, with uintptr_t.
11022 * lisp.h: Prefer 64-bit EMACS_INT if available.
11023 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
11024 on 32-bit hosts that have 64-bit int, so that they can access
11026 However, temporarily disable this change unless the temporary
11027 symbol WIDE_EMACS_INT is defined.
11029 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
11031 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
11032 This removes an assumption that EMACS_INT and long are the same
11033 width as pointers. The assumption is true for Emacs porting targets
11034 now, but we want to make other targets possible.
11035 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
11036 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
11037 In the rest of the code, change types of integers that hold casted
11038 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
11039 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
11040 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
11041 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
11042 No need to cast type when ORing.
11043 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
11044 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
11045 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
11046 assume EMACS_INT is the same width as char *.
11047 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
11048 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
11049 Remove no-longer-needed casts.
11050 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
11051 (xg_tool_bar_help_callback, xg_make_tool_item):
11052 Use EMACS_INTPTR to hold an integer
11053 that will be cast to void *; this can avoid a GCC warning
11054 if EMACS_INT is not the same width as void *.
11055 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
11056 * xdisp.c (display_echo_area_1, resize_mini_window_1):
11057 (current_message_1, set_message_1):
11058 Use a local to convert to proper width without a cast.
11059 * xmenu.c (dialog_selection_callback): Likewise.
11061 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
11062 Also, don't assume VALBITS / RAND_BITS is less than 5,
11063 and don't rely on undefined behavior when shifting a 1 left into
11065 * lisp.h (get_random): Change signature to match.
11067 * lread.c (hash_string): Use size_t, not int, for hash computation.
11068 Normally we prefer signed values; but hashing is special, because
11069 it's better to use unsigned division on hash table sizes so that
11070 the remainder is nonnegative. Also, size_t is the natural width
11071 for hashing into memory. The previous code used 'int', which doesn't
11072 retain enough info to hash well into very large tables.
11073 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
11075 * dbusbind.c: Don't possibly lose pointer info when converting.
11076 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
11077 Use XPNTR rather than XHASH, so that the high-order bits of
11078 the pointer aren't lost when converting through void *.
11080 * eval.c (Fautoload): Don't double-shift a pointer.
11082 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
11084 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
11086 * gnutls.c (DEF_GNUTLS_FN):
11087 * image.c (DEF_IMGLIB_FN): Make function pointers static.
11089 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
11091 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
11094 2011-05-05 Eli Zaretskii <eliz@gnu.org>
11096 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
11097 New version that can reserve upto 2GB of heap space.
11099 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
11101 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
11103 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
11105 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
11106 `gnutls_certificate_set_x509_key_file'.
11108 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
11110 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
11111 Update dependencies.
11113 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
11115 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
11116 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
11117 Remove unused parameter `fildes'.
11118 * process.c (read_process_output, send_process): Don't pass it.
11120 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
11122 Fix previous change: the library cache is defined in w32.c.
11123 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
11124 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
11126 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
11128 Implement dynamic loading of GnuTLS on Windows.
11130 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
11131 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
11132 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
11135 * gnutls.c (Qgnutls_dll): Define.
11136 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
11137 (gnutls_*): Declare function pointers.
11138 (init_gnutls_functions): New function to initialize function pointers.

11141 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
11142 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
11143 (emacs_gnutls_write, emacs_gnutls_read)
11144 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
11145 (Fgnutls_available_p): New function.
11146 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.

11158 * w32.c (QCloaded_from, Vlibrary_cache): Define.
11159 (w32_delayed_load): Move from image.c. When loading a library, record
11160 its filename in the :loaded-from property of the library id.
11161 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
11162 Initialize and staticpro them.
11163 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
11165 * process.c: Include lisp.h before w32.h, not after.
11166 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
11167 instead of gnutls_record_check_pending.
11169 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
11171 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
11173 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
11174 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
11177 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
11179 * xterm.c (x_set_frame_alpha): Do not set property on anything
11180 else than FRAME_X_OUTER_WINDOW (Bug#8608).
11182 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
11184 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
11186 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
11188 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)

11198 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
11200 * callproc.c: Indentation fixup.
11202 * sysdep.c (wait_for_termination_1): Make static.
11203 (wait_for_termination, interruptible_wait_for_termination):
11204 Move after wait_for_termination_1.
11206 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
11208 * sysdep.c (interruptible_wait_for_termination): New function
11209 which is like wait_for_termination, but allows keyboard
11212 * callproc.c (Fcall_process): Add (:file "file") as an option for
11214 (Fcall_process_region): Ditto.
11216 2011-04-30 Eli Zaretskii <eliz@gnu.org>
11218 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
11219 rather than `XVECTOR (FOO)->size'.
11221 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
11222 inttypes.h, as a gnulib replacement is used if it not available in
11225 2011-04-21 Eli Zaretskii <eliz@gnu.org>
11227 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
11228 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
11229 of MOST_POSITIVE_FIXNUM. (Bug#8528)
11231 * coding.c (coding_alloc_by_realloc): Error out if destination
11232 will grow beyond MOST_POSITIVE_FIXNUM.
11233 (decode_coding_emacs_mule): Abort if there isn't enough place in
11234 charbuf for the composition carryover bytes. Reserve an extra
11235 space for up to 2 characters produced in a loop.
11236 (decode_coding_iso_2022): Abort if there isn't enough place in
11237 charbuf for the composition carryover bytes.

11243 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
11244 %llo or %llx format is passed. (Bug#8545)
11246 * window.c (window_scroll_line_based): Use a marker instead of
11247 simple variables to record original value of point. (Bug#7952)
11249 * doprnt.c (doprnt): Fix the case where a multibyte sequence
11250 produced by %s or %c overflows available buffer space. (Bug#8545)
11252 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
11254 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

11287 2011-04-27 Eli Zaretskii <eliz@gnu.org>
11289 Improve `doprnt' and its usage. (Bug#8545)
11290 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
11291 `format_end'. Remove support for %l as a conversion specifier.
11292 Don't use xrealloc. Improve diagnostics when the %l size modifier
11293 is used. Update the commentary.
11295 * eval.c (verror): Simplify calculation of size_t.
11297 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
11300 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
11302 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
11305 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
11307 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
11308 This makes this file independent of the recent pseudovector change.
11310 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
11312 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
11314 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
11315 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
11316 Remove unused local.
11317 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
11319 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
11320 GCC 4.6.0 optimizes based on type-based alias analysis.
11321 For example, if b is of type struct buffer * and v of type struct
11322 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
11323 != &v->size, and therefore "v->size = 1; b->size = 2; return
11324 v->size;" must therefore return 1. This assumption is incorrect
11325 for Emacs, since it type-puns struct Lisp_Vector * with many other
11326 types. To fix this problem, this patch adds a new type struct
11327 vectorlike_header that documents the constraints on layout of vectors
11328 and pseudovectors, and helps optimizing compilers not get fooled
11329 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
11330 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
11331 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
11333 (XSETPVECTYPE): Rewrite in terms of new macro.
11334 (XSETPVECTYPESIZE): New macro, specifying both type and size.
11335 This is a bit clearer, and further avoids the possibility of
11336 undesirable aliasing.
11337 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
11338 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
11339 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
11340 since Lisp_Subr is a special case (no "next" field).
11341 (ASIZE): Now uses header.size rather than size.
11342 All previous uses of XVECTOR (foo)->size replaced to use this macro,
11343 to avoid the hassle of writing XVECTOR (foo)->header.size.
11344 (struct vectorlike_header): New type.
11345 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
11346 object, to help avoid aliasing.
11347 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
11348 (SUBRP): Likewise, since Lisp_Subr is a special case.
11349 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
11350 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
11351 (struct Lisp_Hash_Table): Combine first two members into a single
11352 struct vectorlike_header member. All uses of "size" and "next" members
11353 changed to be "header.size" and "header.next".
11354 * buffer.h (struct buffer): Likewise.
11355 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
11356 * frame.h (struct frame): Likewise.
11357 * process.h (struct Lisp_Process): Likewise.
11358 * termhooks.h (struct terminal): Likewise.
11359 * window.c (struct save_window_data, struct saved_window): Likewise.
11360 * window.h (struct window): Likewise.
11361 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
11362 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
11363 * buffer.c (init_buffer_once): Likewise.
11364 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
11366 * process.c (Fformat_network_address): Use local var for size,
11369 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
11371 Make the Lisp reader and string-to-float more consistent (Bug#8525)
11372 * data.c (atof): Remove decl; no longer used or needed.
11373 (digit_to_number): Move to lread.c.
11374 (Fstring_to_number): Use new string_to_number function, to be
11375 consistent with how the Lisp reader treats infinities and NaNs.
11376 Do not assume that floating-point numbers represent EMACS_INT
11377 without losing information; this is not true on most 64-bit hosts.
11378 Avoid double-rounding errors, by insisting on integers when
11379 parsing non-base-10 numbers, as the documentation specifies.
11380 * lisp.h (string_to_number): New decl, replacing ...
11381 (isfloat_string): Remove.
11382 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
11383 (read1): Do not accept +. and -. as integers; this
11384 appears to have been a coding error. Similarly, do not accept
11385 strings like +-1e0 as floating point numbers. Do not report
11386 overflow for integer overflows unless the base is not 10 which
11387 means we have no simple and reliable way to continue.
11388 Break out the floating-point parsing into a new
11389 function string_to_number, so that Fstring_to_number parses
11390 floating point numbers consistently with the Lisp reader.
11391 (digit_to_number): Move here from data.c. Make it static inline.
11392 (E_CHAR, EXP_INT): Remove, replacing with ...
11393 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
11394 (string_to_number): New function, replacing isfloat_string.
11395 This function checks for valid syntax and produces the resulting
11396 Lisp float number too. Rework it so that string-to-number
11397 no longer mishandles examples like "1.0e+". Use strtoumax,
11398 so that overflow for non-base-10 numbers is reported only when
11399 there's no portable and simple way to convert to floating point.
11401 * textprop.c (set_text_properties_1): Rewrite for clarity,
11402 and to avoid GCC warning about integer overflow.
11404 * intervals.h (struct interval): Use EMACS_INT for members
11405 where EMACS_UINT might cause problems. See
11406 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
11407 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
11408 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
11410 (offset_intervals): Tell GCC not to worry about length overflow
11411 when negating a negative length.
11413 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
11414 (overrun_check_free): Likewise.
11416 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
11417 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
11420 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
11421 (gnutls_make_error): Rename local to avoid shadowing.
11422 (gnutls_emacs_global_deinit): ifdef out; not used.
11423 (Fgnutls_boot): Use const for pointer to readonly storage.
11424 Comment out unused local. Fix pointer signedness problems.
11426 * lread.c (openp): Don't stuff size_t into an 'int'.
11427 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
11428 about possible signed overflow.
11430 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
11431 (GDK_KEY_g): Don't define if already defined.
11432 (xg_prepare_tooltip): Avoid pointer signedness problem.
11433 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
11435 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
11436 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
11438 * xfns.c (Fx_window_property): Simplify a bit,
11439 to make a bit faster and to avoid GCC 4.6.0 warning.
11440 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
11442 * fns.c (internal_equal): Don't assume size_t fits in int.
11444 * alloc.c (compact_small_strings): Tighten assertion a little.
11446 Replace pEd with more-general pI, and fix some printf arg casts.
11447 * lisp.h (pI): New macro, generalizing old pEd macro to other
11448 conversion specifiers. For example, use "...%"pI"d..." rather
11449 than "...%"pEd"...".
11450 (pEd): Remove. All uses replaced with similar uses of pI.
11451 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
11452 * alloc.c (check_pure_size): Don't overflow by converting size to int.
11453 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
11454 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
11455 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
11456 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
11457 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
11459 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
11460 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
11461 * print.c (safe_debug_print, print_object): Likewise.
11462 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
11464 Use pI instead of if-then-else-abort. Use %p to avoid casts,
11465 avoiding the 0 flag, which is not portable.
11466 * process.c (Fmake_network_process): Use pI to avoid cast.
11467 * region-cache.c (pp_cache): Likewise.
11468 * xdisp.c (decode_mode_spec): Likewise.
11469 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
11470 behavior on 64-bit hosts with printf arg.
11471 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
11472 (x_stop_queuing_selection_requests): Likewise.
11473 (x_get_window_property): Don't truncate byte count to an 'int'
11476 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
11477 here, since it parses constructs like leading '-' and spaces,
11478 which are not wanted; and it overflows with large numbers.
11479 Instead, simply match F[0-9]+, which is what is wanted anyway.
11481 * alloc.c: Remove unportable assumptions about struct layout.
11482 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
11483 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
11484 (allocate_vectorlike, make_pure_vector): Use the new macros,
11485 plus offsetof, to remove unportable assumptions about struct layout.
11486 These assumptions hold on all porting targets that I know of, but
11487 they are not guaranteed, they're easy to remove, and removing them
11488 makes further changes easier.
11490 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
11491 This doesn't fix a bug but makes the code clearer.
11492 (string_overrun_cookie): Now const. Use initializers that
11493 don't formally overflow signed char, to avoid warnings.
11494 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
11495 can cause Emacs to crash when string overrun checking is enabled.
11496 (allocate_buffer): Don't assume sizeof (struct buffer) is a
11497 multiple of sizeof (EMACS_INT); it need not be, if
11498 alignof(EMACS_INT) < sizeof (EMACS_INT).
11499 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
11501 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

11508 supposed to be handshaking. (Bug#8556)
11509 Reported by Paul Eggert <eggert@cs.ucla.edu>.

11528 2011-04-25 Eli Zaretskii <eliz@gnu.org>
11530 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
11531 "cast to pointer from integer of different size".
11533 Improve doprnt and its use in verror. (Bug#8545)
11534 * doprnt.c (doprnt): Document the set of format control sequences
11535 supported by the function. Use SAFE_ALLOCA instead of always
11538 * eval.c (verror): Don't limit the buffer size at size_max-1, that
11539 is one byte too soon. Don't use xrealloc; instead xfree and
11542 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
11544 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
11547 * gnutls.c: Renamed global_initialized to
11548 gnutls_global_initialized. Added internals for the
11549 :verify-hostname-error, :verify-error, and :verify-flags
11550 parameters of `gnutls-boot' and documented those parameters in the
11551 docstring. Start callback support.
11552 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
11553 unless a fatal error occurred. Call gnutls_alert_send_appropriate

11626 * doprnt.c: Include limits.h.
11627 (SIZE_MAX): New macro.
11628 (doprnt): Return a size_t value. 2nd arg is now size_t.
11629 Many local variables are now size_t instead of int or unsigned.
11630 Improve overflow protection. Support `l' modifier for integer
11631 conversions. Support %l conversion. Don't assume an EMACS_INT
11632 argument for integer conversions and for %c.
11634 * lisp.h (doprnt): Restore prototype.
11636 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
11637 $(SRC)/character.h.
11639 * Makefile.in (base_obj): Add back doprnt.o.
11641 * deps.mk (doprnt.o): Add back prerequisites.
11642 (callint.o): Depend on character.h.
11644 * eval.c (internal_lisp_condition_case): Include the handler
11645 representation in the error message.

11651 * callint.c (Fcall_interactively): When displaying error message
11652 about invalid control letter, pass the character's codepoint, not
11653 a pointer to its multibyte form. Improve display of the character
11654 in octal and display also its hex code.
11656 * character.c (char_string): Use %x to display the (unsigned)
11657 codepoint of an invalid character, to avoid displaying a bogus
11660 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
11661 `error', not SYMBOL_NAME itself.
11663 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
11664 character arguments to `error'.
11666 * charset.c (check_iso_charset_parameter): Fix incorrect argument
11667 to `error' in error message about FINAL_CHAR argument. Make sure
11668 FINAL_CHAR is a character, and use %c when it is passed as

11739 * dispextern.h (struct redisplay_interface): Rename param
11740 to avoid shadowing.
11741 * termhooks.h (struct terminal): Likewise.
11742 * xterm.c (xembed_send_message): Likewise.
11744 * insdel.c (make_gap_smaller): Define only if
11745 USE_MMAP_FOR_BUFFERS || REL_ALLOC || DOUG_LEA_MALLOC.
11747 * keyboard.c (read_char): Make a var volatile so longjmp won't clobber
11750 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
11751 so that we aren't warned about unused symbols.
11753 * xfns.c (Fx_file_dialog): Rename local to avoid shadowing.
11755 * xdisp.c (x_produce_glyphs): Mark var as initialized (Bug#8512).

11768 if defined HAVE_MENUS && !defined USE_X_TOOLKIT && !defined USE_GTK.
11770 * xmenu.c (menu_help_callback): Pointer type fixes.

11788 compatible char. Avoid the old compiler warnings about
11789 out-of-range initializers by using, for example, '\xab' rather
11792 * xgselect.c (xgselect_initialize): Check vs interface
11793 even if ! (defined (USE_GTK) || defined (HAVE_GCONF)).

11858 * nsfont.m: Fixed bugs in ns_get_family and
11859 ns_descriptor_to_entity that were caused by using free to
11860 deallocate memory blocks that were allocated by xmalloc (via
11861 xstrdup). This caused Emacs to crash when compiled with
11862 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
11863 --enable-checking=xmallocoverrun). xfree is now used to
11864 deallocate these memory blocks.

12260 * sound.c, syntax.c, textprop.c, window.c, xdisp.c, xfaces.c, xfns.c:
12261 * xmenu.c, xselect.c:
12262 Declare Q* vars static if they are not used in other modules.
12263 * ccl.h, character.h, charset.h, coding.h, composite.h, font.h:
12264 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
12265 Remove decls of unexported vars.
12266 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
12268 * lisp.h (DEFINE_FUNC): Make sname 'static'.
12270 Make Emacs functions such as Fatom 'static' by default.
12271 This makes it easier for human readers (and static analyzers)
12272 to see whether these functions can be called from other modules.
12273 DEFUN now defines a static function. To make the function external
12274 so that it can be used in other C modules, use the new macro DEFUE.
12275 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
12276 (Finit_image_library):
12277 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
12278 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
12279 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
12280 Remove decls, since these functions are now static.
12281 (Funintern, Fget_internal_run_time): New decls, since these functions
12282 were already external.
12284 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
12285 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:

12291 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
12292 Mark functions with DEFUE instead of DEFUN,
12293 if they are used in other modules.
12294 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
12295 decls for now-static functions.
12296 * buffer.h (Fdelete_overlay): Remove decl.
12297 * callproc.c (Fgetenv_internal): Mark as internal.
12298 * composite.c (Fremove_list_of_text_properties): Remove decl.

12302 * doc.c (Fdocumntation_property): New forward static decl.
12303 * eval.c (Ffetch_bytecode): New forward static decl.
12304 (Funintern): Remove extern decl; now in .h file where it belongs.
12305 * fileio.c (Fmake_symbolic_link): New forward static decl.
12306 * image.c (Finit_image_library): New forward static decl.
12307 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
12308 * intervals.h (Fprevious_property_change):
12309 (Fremove_list_of_text_properties): Remove decls.
12310 * keyboard.c (Fthis_command_keys): Remove decl.
12311 (Fcommand_execute): New forward static decl.
12312 * keymap.c (Flookup_key): New forward static decl.
12313 (Fcopy_keymap): Now static.
12314 * keymap.h (Flookup_key): Remove decl.
12315 * process.c (Fget_process): New forward static decl.

12327 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
12329 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
12332 2011-04-13 Eli Zaretskii <eliz@gnu.org>
12334 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
12335 when at ZV. (Bug#8487)
12337 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
12339 * charset.c (Fclear_charset_maps): Use xfree instead of free.
12341 * keyboard.c (parse_tool_bar_item): Likewise.
12342 * sound.c (sound_cleanup, alsa_close): Likewise.
12343 * termcap.c (tgetent): Likewise.
12344 * xfns.c (x_default_font_parameter): Likewise.
12345 * xsettings.c (read_and_apply_settings): Likewise.
12347 * alloc.c (overrun_check_malloc, overrun_check_realloc)
12348 (overrun_check_free): Protoize.
12350 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
12352 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
12353 since callers should never pass a negative size.
12354 Change the signature to match that of plain 'read' and 'write'; see
12355 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
12356 * lisp.h: Update prototypes of emacs_write and emacs_read.
12358 2011-04-11 Eli Zaretskii <eliz@gnu.org>
12360 * xdisp.c (redisplay_window): Don't try to determine the character
12361 position of the scroll margin if the window start point w->startp
12362 is outside the buffer's accessible region. (Bug#8468)
12364 2011-04-10 Eli Zaretskii <eliz@gnu.org>
12366 Fix write-region and its subroutines for buffers > 2GB.
12367 * fileio.c (a_write, e_write): Modify declaration of arguments and
12368 local variables to support buffers larger than 2GB.
12369 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
12371 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
12372 argument, local variables, and return value.
12374 * lisp.h: Update prototypes of emacs_write and emacs_read.
12376 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
12378 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
12380 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
12382 Fix more problems found by GCC 4.6.0's static checks.
12384 * xdisp.c (vmessage): Use a better test for character truncation.
12386 * charset.c (load_charset_map): <, not <=, for optimization,
12387 and to avoid potential problems with integer overflow.
12388 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
12389 * casetab.c (set_identity, shuffle): Likewise.
12390 * editfns.c (Fformat): Likewise.
12391 * syntax.c (skip_chars): Likewise.
12393 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
12394 This also lets GCC 4.6.0 generate slightly better loop code.
12396 * callint.c (Fcall_interactively): <, not <=, for optimization.
12397 (Fcall_interactively): Count the number of arguments produced,
12398 not the number of arguments given. This is simpler and lets GCC
12399 4.6.0 generate slightly better code.
12401 * ftfont.c: Distingish more carefully between FcChar8 and char.
12402 The previous code passed unsigned char * to a functions like
12403 strlen and xstrcasecmp that expect char *, which does not
12404 conform to the C standard.
12405 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
12406 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
12407 char * when the C standard requires it.
12409 * keyboard.c (read_char): Remove unused var.
12411 * eval.c: Port to Windows vsnprintf (Bug#8435).
12412 Include <limits.h>.
12413 (SIZE_MAX): Define if the headers do not.
12414 (verror): Do not give up if vsnprintf returns a negative count.
12415 Instead, grow the buffer. This ports to Windows vsnprintf, which
12416 does not conform to C99. Problem reported by Eli Zaretskii.
12417 Also, simplify the allocation scheme, by avoiding the need for
12418 calling realloc, and removing the ALLOCATED variable.
12420 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
12422 Remove invocations of doprnt, as Emacs now uses vsnprintf.
12423 But keep the doprint source code for now, as we might revamp it
12424 and use it again (Bug#8435).
12425 * lisp.h (doprnt): Remove.
12426 * Makefile.in (base_obj): Remove doprnt.o.
12427 * deps.mk (doprnt.o): Remove.
12429 error: Print 32- and 64-bit integers portably (Bug#8435).
12430 Without this change, on typical 64-bit hosts error ("...%d...", N)
12431 was used to print both 32- and 64-bit integers N, which relied on
12432 undefined behavior.
12433 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
12434 * lisp.h (error, verror): Mark as printf-like functions.
12435 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
12436 Report overflow in size calculations when allocating printf buffer.
12437 Do not truncate output string at its first null byte.
12438 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
12439 Truncate the output at a character boundary, since vsnprintf does not
12441 * charset.c (check_iso_charset_parameter): Convert internal
12442 character to string before calling 'error', since %c now has the
12444 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
12445 overflow when computing char to be passed to 'error'. Do not
12446 pass Lisp_Object to 'error'; pass the integer instead.
12447 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
12448 formatted with plain %d.
12450 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
12452 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
12454 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
12456 * xterm.c (x_catch_errors): Remove duplicate declaration.
12458 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
12460 * xdisp.c, lisp.h (message_nolog): Remove; unused.
12462 2011-04-10 Jim Meyering <meyering@redhat.com>
12464 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
12465 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
12466 return ssize_t not "int", and use size_t as the buffer length.
12467 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
12468 * gnutls.h: Update declarations.
12469 * process.c (read_process_output): Use ssize_t, to match.
12470 (send_process): Likewise.
12472 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
12474 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
12476 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
12478 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
12479 Use unsigned char, to match FcChar8 type definition.
12481 * xterm.c (handle_one_xevent):
12482 * xmenu.c (create_and_show_popup_menu):
12483 * xselect.c (x_decline_selection_request)
12484 (x_reply_selection_request): Avoid type-punned deref of X events.
12486 2011-04-09 Eli Zaretskii <eliz@gnu.org>
12488 Fix some uses of `int' instead of EMACS_INT.
12489 * search.c (string_match_1, fast_string_match)
12490 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
12491 (scan_buffer, find_next_newline_no_quit)
12492 (find_before_next_newline, search_command, Freplace_match)
12493 (Fmatch_data): Make some `int' variables be EMACS_INT.
12495 * xdisp.c (display_count_lines): 3rd argument and return value now
12496 EMACS_INT. All callers changed.
12497 (pint2hrstr): Last argument is now EMACS_INT.
12499 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
12500 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
12501 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
12502 (decode_coding_utf_16, decode_coding_emacs_mule)

12504 (decode_coding_ccl, decode_coding_charset)
12505 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
12506 (decode_coding_iso_2022, decode_coding_emacs_mule)
12507 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
12508 <char_offset, last_offset>: Declare EMACS_INT.

12510 (encode_coding_emacs_mule, encode_invocation_designation)
12511 (encode_designation_at_bol, encode_coding_iso_2022)
12512 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
12513 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
12515 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
12516 (encode_invocation_designation): Last argument P_NCHARS is now
12518 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
12519 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
12521 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
12524 * ccl.c (Fccl_execute_on_string): Declare some variables
12527 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
12529 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
12531 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
12533 * process.c (Fformat_network_address): Doc fix.
12535 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
12537 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
12539 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
12541 * keyboard.c (read_char): Call Lisp function help-form-show,
12542 instead of using internal_with_output_to_temp_buffer.
12543 (Qhelp_form_show): New var.
12544 (syms_of_keyboard): Use DEFSYM macro.
12546 * print.c (internal_with_output_to_temp_buffer): Function deleted.

12550 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
12552 * process.c (Flist_processes): Remove to Lisp.
12553 (list_processes_1): Delete.
12555 2011-04-06 Eli Zaretskii <eliz@gnu.org>
12557 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
12559 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
12561 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
12563 Fix more problems found by GCC 4.6.0's static checks.
12565 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
12567 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
12569 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
12571 * xdisp.c (vmessage): Mark as a printf-like function.
12573 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
12575 * sound.c (sound_warning): Don't crash if arg contains a printf format.

12580 to system-supplied API.
12582 * eval.c (Fsignal): Remove excess argument to 'fatal'.
12584 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
12585 This avoids several warnings with gcc -Wstrict-overflow.
12586 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
12587 directly, rather than having caller test rule sign. This avoids
12588 some unnecessary tests.
12589 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
12590 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
12591 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
12593 * xfont.c (xfont_text_extents): Remove var that was set but not used.
12594 (xfont_open): Avoid unnecessary tests.
12596 * composite.c (composition_gstring_put_cache): Use unsigned integer.

12605 by using the new macro.
12607 * textprop.c (set_text_properties_1): Change while to do-while,
12608 since the condition is always true at first.
12610 * intervals.c (graft_intervals_into_buffer): Mark var as used.
12611 (interval_deletion_adjustment): Return unsigned value.
12614 * process.c (list_processes_1, create_pty, read_process_output):

12624 (update_syntax_table): Use unsigned instead of int.
12626 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
12627 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
12628 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
12630 * print.c (print_error_message): Avoid int overflow.
12632 * font.c (font_list_entities): Redo for clarity,
12633 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
12635 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
12636 (font_score): Avoid potential overflow in diff calculation.
12638 * fns.c (substring_both): Remove var that is set but not used.
12639 (sxhash): Redo loop for clarity and to avoid wraparound warning.
12641 * eval.c (funcall_lambda): Rename local to avoid shadowing.
12643 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
12644 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
12645 can always succeed if overflow has undefined behavior.
12647 * search.c (boyer_moore, wordify): Remove vars set but not used.
12648 (wordify): Omit three unnecessary tests.
12650 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
12651 All callers changed. This avoids the need for an unused var.
12653 * casefiddle.c (casify_region): Remove var that is set but not used.
12655 * dired.c (file_name_completion): Remove var that is set but not used.
12657 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
12659 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
12660 (Finsert_file_contents): Remove unnecessary code checking fd.
12662 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
12663 Check for integer overflow on size calculations.
12665 * buffer.c (Fprevious_overlay_change): Remove var that is set
12668 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
12669 Remove vars that are set but not used.
12670 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
12671 (timer_check_2): Mark vars as initialized.
12673 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
12675 * image.c (lookup_image): Remove var that is set but not used.
12676 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
12678 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
12679 that are set but not used.
12681 * xfns.c (make_invisible_cursor): Don't return garbage
12682 if XCreateBitmapFromData fails (Bug#8410).
12684 * xselect.c (x_get_local_selection, x_handle_property_notify):
12685 Remove vars that are set but not used.
12687 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
12688 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
12690 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
12691 Remove var that is set but not used.
12692 (scroll_bar_windows_size): Now size_t, not int.
12693 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
12694 Check for overflow.
12696 * xfaces.c (realize_named_face): Remove vars that are set but not used.
12697 (map_tty_color) [!defined MSDOS]: Likewise.
12699 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
12701 * coding.c: Remove vars that are set but not used.
12702 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.

12709 that is set but not used.
12711 * print.c (print_object): Remove var that is set but not used.
12713 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
12714 The gnulib version avoids calling malloc in the usual case,
12715 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
12716 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
12717 * filelock.c (current_lock_owner): Likewise.
12718 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
12719 * sysdep.c: Include allocator.h, careadlinkat.h.
12720 (emacs_no_realloc_allocator): New static constant.
12721 (emacs_readlink): New function.
12722 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
12723 ../lib/careadlinkat.h.
12725 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
12727 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the

12749 do not dereference NULL upon failed strdup
12750 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
12751 (ns_get_family): Likewise.
12753 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
12755 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
12757 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
12759 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
12762 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
12764 Add lexical binding.
12766 * window.c (Ftemp_output_buffer_show): New fun.
12767 (Fsave_window_excursion):
12768 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.

12773 Bind Qinternal_interpreter_environment.
12774 (Feval_buffer): Bind Qlexical_binding.
12775 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
12777 (syms_of_lread): Declare `lexical-binding'.
12779 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
12781 * keyboard.c (eval_dyn): New fun.
12782 (menu_item_eval_property): Use it.
12784 * image.c (parse_image_spec): Use Ffunctionp.
12786 * fns.c (concat, mapcar1): Accept byte-code-functions.
12788 * eval.c (Fsetq): Handle lexical vars.
12789 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
12790 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
12791 (FletX, Flet): Obey lexical binding.
12792 (Fcommandp): Handle closures.
12793 (Feval): New `lexical' arg.
12794 (eval_sub): New function extracted from Feval. Use it almost
12795 everywhere where Feval was used. Look up vars in lexical env.
12797 (Ffunctionp): Move from subr.el.
12798 (Ffuncall): Handle closures.
12799 (apply_lambda): Remove `eval_flags'.
12800 (funcall_lambda): Handle closures and new byte-code-functions.
12801 (Fspecial_variable_p): New function.
12802 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
12803 but without exporting it to Lisp.
12805 * doc.c (Fdocumentation, store_function_docstring):
12806 * data.c (Finteractive_form): Handle closures.
12808 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
12811 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
12813 (exec_byte_code): New function extracted from Fbyte_code to handle new
12814 calling convention for byte-code-functions. Add new byte-codes.
12816 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
12818 * alloc.c (Fmake_symbol): Init new `declared_special' field.
12820 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
12822 * xdisp.c (redisplay_internal): Fix prototype.
12824 2011-03-31 Eli Zaretskii <eliz@gnu.org>
12826 * xdisp.c (SCROLL_LIMIT): New macro.
12827 (try_scrolling): Use it when setting scroll_limit.
12828 Limit scrolling to 100 screen lines.
12829 (redisplay_window): Even when falling back on "recentering",
12830 position point in the window according to scroll-conservatively,
12831 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
12833 (try_scrolling): When point is above the window, allow searching
12834 as far as scroll_max, or one screenful, to compute vertical
12835 distance from PT to the scroll margin position. This prevents
12836 try_scrolling from unnecessarily failing when
12837 scroll-conservatively is set to a value slightly larger than the
12838 window height. Clean up the case of PT below the margin at bottom
12839 of window: scroll_max can no longer be INT_MAX. When aggressive
12840 scrolling is in use, don't let point enter the opposite scroll
12841 margin as result of the scroll.
12842 (syms_of_xdisp) <scroll-conservatively>: Document the
12843 threshold of 100 lines for never-recentering scrolling.

12850 (message_log_check_duplicate): Remove parameters `prev_bol' and
12851 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
12852 (redisplay_internal): Remove parameter `preserve_echo_area',
12853 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
12855 * indent.c (Fvertical_motion):
12856 * window.c (window_scroll_pixel_based, Frecenter):
12857 Don't pass `need_y_p' to `move_it_by_lines'.
12859 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
12861 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
12862 steal a few bits to be more compact.
12863 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
12864 Remove unneeded casts.
12866 * bytecode.c (Fbyte_code): CAR and CDR can GC.
12868 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
12870 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
12871 binding" message (bug#7967).
12873 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
12875 Fix more problems found by GCC 4.6.0's static checks.
12877 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
12878 Remove unused local var.
12880 * editfns.c (Fmessage_box): Remove unused local var.
12882 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
12883 (note_mode_line_or_margin_highlight, note_mouse_highlight):
12884 Omit unused local vars.
12885 * window.c (shrink_windows): Omit unused local var.
12886 * menu.c (digest_single_submenu): Omit unused local var.
12887 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
12888 Omit unused local var.
12890 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
12891 Don't assume string length fits in int.
12892 (keyremap_step, read_key_sequence): Use size_t for sizes.
12893 (read_key_sequence): Don't check last_real_key_start redundantly.
12895 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
12896 instead of alloca (Bug#8344).
12898 * eval.c (Fbacktrace): Don't assume nargs fits in int.
12899 (Fbacktrace_frame): Don't assume nframes fits in int.
12901 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

12908 * cm.c (calccost): Turn while-do into do-while, for clarity.
12910 * keyboard.c (syms_of_keyboard): Use the same style as later
12911 in this function when indexing through an array. This also
12912 works around GCC bug 48267.
12914 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
12916 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
12918 * chartab.c (sub_char_table_ref_and_range): Redo for slight
12919 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
12921 * keyboard.c, keyboard.h (num_input_events): Now size_t.
12922 This avoids undefined behavior on integer overflow, and is a bit
12923 more convenient anyway since it is compared to a size_t variable.
12925 Variadic C functions now count arguments with size_t, not int.
12926 This avoids an unnecessary limitation on 64-bit machines, which
12927 caused (substring ...) to crash on large vectors (Bug#8344).

12937 * fns.c (concat): Likewise.
12938 * frame.c (x_set_frame_parameters): Likewise.
12939 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
12940 0 if not found, not -1. All callers changed.
12942 * alloc.c (garbage_collect): Don't assume stack size fits in int.
12943 (stack_copy_size): Now size_t, not int.
12944 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
12946 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
12948 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',

12965 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
12966 don't set the hook to nil, but remove the offending function instead.
12967 (Qcommand_hook_internal): Remove, unused.
12968 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
12969 Vcommand_hook_internal.
12971 * eval.c (enum run_hooks_condition): Remove.
12972 (funcall_nil, funcall_not): New functions.
12973 (run_hook_with_args): Call each function through a `funcall' argument.

12987 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.

13137 2011-03-23 Julien Danjou <julien@danjou.info>
13139 * term.c (Fsuspend_tty, Fresume_tty):
13140 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
13141 * window.c (temp_output_buffer_show):
13142 * insdel.c (signal_before_change):
13143 * frame.c (Fhandle_switch_frame):
13144 * fileio.c (Fdo_auto_save):
13145 * emacs.c (Fkill_emacs):
13146 * editfns.c (save_excursion_restore):
13147 * cmds.c (internal_self_insert):
13148 * callint.c (Fcall_interactively):
13149 * buffer.c (Fkill_all_local_variables):
13150 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
13152 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
13153 unconditionally since it does the check itself.
13155 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
13157 Fix more problems found by GCC 4.5.2's static checks.
13159 * coding.c (encode_coding_raw_text): Avoid unnecessary test
13160 the first time through the loop, since we know p0 < p1 then.
13161 This also avoids a gcc -Wstrict-overflow warning.
13163 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
13164 leading to a memory leak, possible in functions like
13165 load_charset_map_from_file that can allocate an unbounded number
13166 of objects (Bug#8318).
13168 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
13169 that could (at least in theory) be that large.
13171 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
13172 This is less likely to overflow, and avoids undefined behavior if
13173 overflow does occur. All callers changed. Use strtoul to scan
13174 for the unsigned long integer.
13175 (pint2hrstr): Simplify and tune code slightly.
13176 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
13178 * scroll.c (do_scrolling): Work around GCC bug 48228.
13179 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
13181 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
13182 This also avoids a warning with gcc -Wstrict-overflow.
13183 (validate_x_resource_name): Simplify count usage.
13184 This also avoids a warning with gcc -Wstrict-overflow.
13186 * fileio.c (Fcopy_file): Report error if fchown or fchmod
13189 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
13191 * process.c (Fmake_network_process): Use socklen_t, not int,
13192 where POSIX says socklen_t is required in portable programs.
13193 This fixes a porting bug on hosts like 64-bit HP-UX, where
13194 socklen_t is wider than int (Bug#8277).
13195 (Fmake_network_process, server_accept_connection):
13196 (wait_reading_process_output, read_process_output):
13199 * process.c: Rename or move locals to avoid shadowing.
13200 (list_processes_1, Fmake_network_process):
13201 (read_process_output_error_handler, exec_sentinel_error_handler):
13202 Rename or move locals.
13203 (Fmake_network_process): Define label "retry_connect" only if needed.
13204 (Fnetwork_interface_info): Fix pointer signedness.
13205 (process_send_signal): Add cast to avoid pointer signedness problem.
13206 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
13207 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
13209 Make tparam.h and terminfo.c consistent.
13210 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
13211 Include tparam.h instead, since it declares them.
13212 * cm.h (PC): Remove extern decl; tparam.h now does this.
13213 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
13214 * terminfo.c: Include tparam.h, to check interfaces.
13215 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
13216 (tparam): Adjust signature to match interface in tparam.h;
13217 this removes some undefined behavior. Check that outstring and len
13218 are zero, which they always are with Emacs.
13219 * tparam.h (PC, BC, UP): New extern decls.
13221 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
13222 (xftfont_open): Rename locals to avoid shadowing.
13224 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
13225 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
13226 (OTF_TAG_SYM): Omit macro if not needed.
13227 (ftfont_list): Remove unused local.
13228 (get_adstyle_property, ftfont_pattern_entity):
13229 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
13230 Rename locals to avoid shadowing.
13232 * xfont.c (xfont_list_family): Mark var as initialized.
13234 * xml.c (make_dom): Now static.
13236 * composite.c (composition_compute_stop_pos): Rename local to
13238 (composition_reseat_it): Remove unused locals.
13239 (find_automatic_composition, composition_adjust_point): Likewise.
13240 (composition_update_it): Mark var as initialized.
13241 (find_automatic_composition): Mark vars as initialized,
13242 with a FIXME (Bug#8290).
13244 character.h: Rename locals to avoid shadowing.
13245 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
13246 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
13247 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
13248 (BUF_DEC_POS): Be more systematic about renaming local temporaries
13249 to avoid shadowing.
13251 * textprop.c (property_change_between_p): Remove; unused.
13253 * intervals.c (interval_start_pos): Now static.
13255 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
13257 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
13258 Rename locals to avoid shadowing.
13260 * sound.c (wav_play, au_play, Fplay_sound_internal):
13261 Fix pointer signedness.
13262 (alsa_choose_format): Remove unused local var.
13263 (wav_play): Initialize a variable to 0, to prevent undefined
13264 behavior (Bug#8278).
13266 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
13268 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
13270 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
13271 clobbering (Bug#8298).
13272 * sysdep.c (sys_subshell): Likewise.
13273 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
13275 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
13276 This should get cleaned up, so that child_setup has the
13277 same signature on all platforms.
13279 * callproc.c (call_process_cleanup): Now static.
13280 (relocate_fd): Rename locals to avoid shadowing.
13282 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
13284 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
13285 not to be necessary, and produces flickering.
13287 2011-03-20 Glenn Morris <rgm@gnu.org>
13289 * config.in: Remove file.
13291 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
13293 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
13294 are now in src/globals.h.
13295 (syms_of_minibuf): Remove spurious & from previous change.
13297 2011-03-20 Leo Liu <sdl.web@gmail.com>
13299 * minibuf.c (completing-read-function): New variable.
13300 (completing-read-default): Rename from completing-read.
13301 (completing-read): Call completing-read-function.
13303 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
13305 * xfaces.c (Fx_load_color_file):
13306 Read color file from absolute filename (bug#8250).
13308 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
13310 * makefile.w32-in: Update dependencies.
13312 2011-03-17 Eli Zaretskii <eliz@gnu.org>
13314 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

13318 Fix more problems found by GCC 4.5.2's static checks.
13320 * process.c (make_serial_process_unwind, send_process_trap):
13321 (sigchld_handler): Now static.
13323 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
13324 That way, the code declares only the vars that it needs.
13325 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
13326 * s/cygwin.h (PTY_ITERATION): Likewise.
13327 * s/darwin.h (PTY_ITERATION): Likewise.

13331 * process.c (allocate_pty): Don't declare stb unless it's needed.
13333 * bytecode.c (MAYBE_GC): Rewrite so as not to use empty "else".
13334 (CONSTANTLIM): Remove; unused.
13335 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
13336 Define only if needed.
13338 * unexelf.c (unexec): Name an expression,
13339 to avoid gcc -Wbad-function-cast warning.
13340 Use a different way to cause a compilation error if anyone uses
13341 n rather than nn, a way that does not involve shadowing.
13342 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
13344 * deps.mk (unexalpha.o): Remove; unused.
13346 New file unexec.h, the (simple) interface for unexec (Bug#8267).
13347 * unexec.h: New file.
13348 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
13349 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
13350 Depend on unexec.h.
13351 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
13352 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
13353 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
13354 Change as necessary to match prototype in unexec.h.
13356 * syntax.c (Fforward_comment, scan_lists): Rename locals to avoid
13358 (back_comment, skip_chars): Mark vars as initialized.
13360 * character.h (FETCH_STRING_CHAR_ADVANCE_NO_CHECK, BUF_INC_POS):

13366 * print.c (Fredirect_debugging_output): Fix pointer signedess.
13368 * lisp.h (debug_output_compilation_hack): Add decl here, to avoid
13369 warning when compiling print.c.

13372 instead of using an uninitialized var.
13373 (font_sort_entities): Mark var as initialized.
13375 * character.h (FETCH_CHAR_ADVANCE): Rename locals to avoid shadowing.
13377 * font.c (font_unparse_xlfd): Don't mix pointers to variables with

13389 * floatfns.c (domain_error2): Define only if needed.
13390 (Ffrexp, Fldexp): Rename locals to avoid shadowing.
13392 * alloc.c (mark_backtrace): Move decl from here ...
13393 * lisp.h: ... to here, so that it can be checked.

13401 * callint.c (quotify_arg, quotify_args): Now static.
13402 (Fcall_interactively): Rename locals to avoid shadowing.
13403 Use const pointer when appropriate.
13405 * lisp.h (get_system_name, get_operating_system_release):

13409 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
13410 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
13411 some of which prompt warnings from gcc -Wbad-function-cast.
13412 (Fformat_time_string, Fencode_time, Finsert_char):
13413 (Ftranslate_region_internal, Fformat):
13414 Rename or remove local vars to avoid shadowing.
13415 (Ftranslate_region_internal): Mark var as initialized.
13417 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
13420 * lisp.h (eassert): Check that the argument compiles, even if
13421 ENABLE_CHECKING is not defined.
13423 * data.c (Findirect_variable): Name an expression, to avoid
13424 gcc -Wbad-function-cast warning.
13425 (default_value, arithcompare, arith_driver, arith_error): Now static.

13432 (Fmake_vector, Fvector, Fmake_byte_code, Fgarbage_collect):
13433 Rename locals to avoid shadowing.
13434 (mark_stack): Move local variables into the #ifdef region where
13436 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
13437 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
13439 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
13440 (GC_STRING_CHARS): Remove; not used.
13441 (Fmemory_limit): Cast sbrk's returned value to char *.
13443 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
13444 avoids undefined behavior in theory.
13446 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
13448 Use functions, not macros, for up- and down-casing (Bug#8254).
13449 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
13450 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
13451 to use the following functions instead of these macros.
13452 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
13453 EMACS_INT, since callers assume the returned value fits in int.
13454 (upcase1): Likewise, for UPCASE_TABLE.
13455 (uppercasep, lowercasep, upcase): New static inline functions.
13456 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
13457 the race-condition problem in the old DOWNCASE.
13459 * regex.c (CHARSET_LOOKUP_RANGE_TABLE_RAW, POP_FAILURE_REG_OR_COUNT):
13460 Rename locals to avoid shadowing.
13461 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
13462 (regex_compile, re_search_2, re_match_2_internal):
13463 Remove unused local vars.
13464 (FREE_VAR): Rewrite so as not to use empty "else",
13465 which gcc can warn about.
13466 (regex_compile, re_match_2_internal): Mark locals as initialized.
13467 (RETALLOC_IF): Define only if needed.
13468 (WORDCHAR_P): Likewise. This one is never needed, but is used
13469 only in a comment talking about a compiler bug, so put inside
13470 the #if 0 of that comment.
13471 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
13472 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
13475 * search.c (boyer_moore): Rename locals to avoid shadowing.
13476 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
13477 (PREV_CHAR_BOUNDARY): Likewise.

13487 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
13489 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
13490 Rename locals to avoid shadowing.
13491 (Fvertical_motion): Mark locals as initialized.
13493 * casefiddle.c (casify_object, casify_region): Now static.
13494 (casify_region): Mark local as initialized.
13496 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
13498 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
13499 New macros, so that the caller can use some names other than
13500 gcpro1, gcpro2, etc.
13501 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
13503 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
13504 argument, for consistency with GCPRO2_VAR, etc: it is now the
13505 prefix of the variable, not the variable itself. All uses
13507 * dired.c (directory_files_internal, file_name_completion):
13508 Rename locals to avoid shadowing.
13510 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
13511 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
13512 dired.c's scmp function, had undefined behavior.
13513 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
13514 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
13515 * buffer.h: ... to here, because these macros use current_buffer,
13516 and the new implementation with inline functions needs to have
13517 current_buffer in scope now, rather than later when the macros
13519 (downcase, upcase1): New static inline functions.
13520 (DOWNCASE, UPCASE1): Reimplement using these functions.
13521 This avoids undefined behavior in expressions like
13522 DOWNCASE (x) == DOWNCASE (y), which previously suffered
13523 from race conditions in accessing the global variables
13524 case_temp1 and case_temp2.
13525 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
13526 * lisp.h (case_temp1, case_temp2): Remove their decls.
13527 * character.h (ASCII_CHAR_P): Move from here ...
13528 * lisp.h: ... to here, so that the inline functions mentioned
13529 above can use them.
13531 * dired.c (directory_files_internal_unwind): Now static.
13533 * fileio.c (file_name_as_directory, directory_file_name):
13534 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
13536 (file_name_as_directory): Use const pointers when appropriate.
13537 (Fexpand_file_name): Likewise. In particular, newdir might
13538 point at constant storage, so make it a const pointer.
13539 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
13540 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
13542 (Fset_file_times, Finsert_file_contents, auto_save_error):
13543 Rename locals to avoid shadowing.
13545 * minibuf.c (choose_minibuf_frame_1): Now static.
13546 (Ftry_completion, Fall_completions): Rename or remove locals
13547 to avoid shadowing.
13549 * marker.c (bytepos_to_charpos): Remove; unused.
13551 * lisp.h (verify_bytepos, count_markers): New decls,
13552 so that gcc does not warn that these functions aren't declared.
13554 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
13555 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
13556 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
13557 (copy_text): Remove unused local var.
13559 * filelock.c (within_one_second): Now static.
13560 (lock_file_1): Rename local to avoid shadowing.
13562 * buffer.c (fix_overlays_before): Mark locals as initialized.
13563 (fix_start_end_in_overlays): Likewise. This function should be
13564 simplified by using pointers-to-pointers, but that's a different
13566 (switch_to_buffer_1): Now static.
13567 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
13568 (report_overlay_modification): Rename locals to avoid shadowing.
13570 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
13571 Fix pointer signedness issue.
13572 (sys_subshell): Mark local as volatile if checking for lint,
13573 to suppress a gcc -Wclobbered warning that does not seem to be right.
13574 (MAXPATHLEN): Define only if needed.
13576 * process.c (serial_open, serial_configure): Move decls from here ...
13577 * systty.h: ... to here, so that they can be checked.
13579 * fns.c (get_random, seed_random): Move extern decls from here ...
13580 * lisp.h: ... to here, so that they can be checked.
13582 * sysdep.c (reset_io): Now static.
13583 (wait_for_termination_signal): Remove; unused.
13585 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
13586 (copy_keymap_item, append_key, push_text_char_description):
