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

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

707 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
708 Prefer snprintf to strncpy.
709 * nsterm.m (ns_term_init):
710 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
711 * nsterm.m (ns_term_init):
712 Avoid the need for strncpy, by using build_string or
713 make_unibyte_string directly. Use dtoastr, not snprintf.
714 * process.c (Fmake_network_process): Diagnose service names that
715 are too long, rather than silently truncating them or creating
716 non-null-terminated names.
717 (Fnetwork_interface_info): Likewise, for interface names.
718 * sysdep.c (system_process_attributes) [GNU_LINUX]:
719 Prefer sprintf to strncat.
720 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:

733 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
734 where argument type is known to be a Lisp_Cons.
736 2012-07-10 Tom Tromey <tromey@redhat.com>
738 * bytecode.c (BYTE_CODE_THREADED): New macro.

746 Optimize pure C strings initialization.
747 * lisp.h (make_pure_string): Fix prototype.
748 (build_pure_c_string): New function, defined as static inline. This
749 provides a better opportunity to optimize away calls to strlen when
750 the function is called with compile-time constant argument.
751 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
752 argument, adjust users accordingly. Use build_pure_c_string where
754 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
755 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,

772 swap 1st and 2nd arguments to obey the common convention. Adjust
774 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
776 2012-07-10 Glenn Morris <rgm@gnu.org>

789 O_RDONLY already includes it).
791 Stop ns builds setting the EMACSLOADPATH environment variable.
792 * nsterm.m (ns_load_path): Rename from ns_init_paths.
793 Now it does not set EMACSLOADPATH, just returns the load-path string.
794 * nsterm.h: Update accordingly.
795 * lread.c [HAVE_NS]: Include nsterm.h.
796 (init_lread) [HAVE_NS]: Use ns_load_path.
797 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
799 2012-07-09 Glenn Morris <rgm@gnu.org>
801 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
802 since the included bsd-common.h does so.
804 Stop ns builds setting the EMACSPATH environment variable.
805 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
806 (ns_init_paths): Do not set EMACSPATH.
807 * nsterm.h (ns_exec_path): Add it.
808 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
811 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
813 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
815 * process.c (wait_reading_process_output): 'waitchannels' was unset
816 when read_kbd || !NILP (wait_for_cell); fix this.

832 Minor improvements to make_formatted_string.
833 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t

866 Move marker debugging code under MARKER_DEBUG.
867 * marker.c (MARKER_DEBUG): Move marker debugging code under
868 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
869 for bootstrap with --enable-checking (~3x slowdown reported
870 by Juanma Barranquero <lekktu@gmail.com>).
871 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
873 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>

880 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
881 has no font, use the frame's font. (Bug#11813)
882 (display_line): Add commentary about displaying truncation glyphs
884 (produce_special_glyphs): Move here from term.c.
886 * term.c (produce_special_glyphs): Move to xdisp.c.
888 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
891 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
893 * xdisp.c (display_line): Avoid warning about implicit declaration
896 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
898 * lisp.h: Remove empty conditional.
900 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>

923 * lread.c (load_path_check): New function, split from init_lread.
924 (init_lread): Reorganize. Motivation:
925 If EMACSLOADPATH is set, check/warn about that rather than the
926 defaults, which we are not going to use. Hence we can remove
927 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
928 Don't warn if site-lisp directories are missing.
929 If not installed, start from a blank load-path, since
930 PATH_LOADSEARCH refers to the eventual installation directories.
932 2012-07-07 Eli Zaretskii <eliz@gnu.org>
934 Support truncation and continuation glyphs on GUI frames, when
935 fringes are disabled. (Bug#11832)

944 truncation glyphs overwrite enough glyphs from the current line to
945 have sufficient space in pixels.
946 (display_line): Support truncation and continuation glyphs on GUI
947 frames. If some spare pixels are left on the line after inserting
948 the truncation glyphs, fill that space with a stretch glyph of a
949 suitably computed width.
951 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
952 produce_glyphs, to support GUI sessions.
954 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
956 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
958 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
960 Do not require float-time's arg to fit in time_t (Bug#11825).
961 This works better on hosts where time_t is unsigned, and where
962 float-time is applied to the (negative) difference between two times.
963 * editfns.c (decode_time_components): Last arg is now double *,
964 not int *, and means to store all the result as a double, without
965 worrying about whether the seconds part fits in time_t.
967 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
969 (Ffloat_time): Do not fail merely because the specified time falls
970 outside of time_t range.
972 2012-07-07 Glenn Morris <rgm@gnu.org>
974 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

985 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
987 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).

999 * w32fns.c (Fx_change_window_property): Doc fix.
1001 * w32fns.c (Fx_window_property): Accept the same arguments as the
1002 X Windows version. Doc fix.
1003 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
1005 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
1006 Eli Zaretskii <eliz@gnu.org>
1008 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.

1010 Obsolete settings removed.
1012 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1014 * process.c: Avoid unnecessary calls to gettime.
1015 (wait_reading_process_output): Don't get the time of day
1016 when gobbling data immediately and not waiting, as there's no need
1017 for it in that case. This removes a FIXME.
1019 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
1021 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
1022 is defined (Bug#11768).
1024 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1026 Fix marker debugging code.
1027 * marker.c (byte_char_debug_check): Do not perform the check
1028 if buffer is not multibyte.
1029 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
1030 Call byte_char_debug_check with correct arguments.
1032 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1034 Compile marker debugging code only if ENABLE_CHECKING is defined.
1035 * marker.c (byte_char_debug_check, count_markers):
1036 Use only if ENABLE_CHECKING is defined.
1037 (byte_debug_flag): Remove.
1038 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
1039 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
1041 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1043 Avoid code repetition in marker-related functions.
1044 * marker.c (attach_marker): New function.

1047 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
1048 Consistently rename charno to charpos.
1049 (marker_position): Add eassert.
1050 (marker_byte_position): Convert to eassert.

1062 * lisp.h (build_marker): New prototype.
1063 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
1064 * composite.c (autocmp_chars): Likewise.
1065 * editfns.c (buildmark): Remove.
1066 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
1067 (save_restriction_save): Use build_marker.
1068 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
1069 * window.c (save_window_save): Likewise.
1071 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

1074 to avoid redundant calls to unchain_overlay.
1075 * buffer.c (drop_overlay): New function.
1076 (delete_all_overlays, Fdelete_overlay): Use it.
1077 * minibuf.c (get_minibuffer): Fix comment.
1079 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1081 Port to OpenBSD 5.1 amd64.
1082 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
1083 This is needed for OpenBSD, and should be harmless on all BSD systems.
1084 Also, include <sys/sysctl.h>, as it should be available on all
1085 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
1086 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
1087 use p_pid member, not kp_proc.pid.
1089 2012-07-06 Glenn Morris <rgm@gnu.org>
1091 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
1093 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
1095 More xmalloc and related cleanup.

1103 * sysdep.c, term.c, termcap.c, unexmacosx.c, window.c, xdisp.c:
1104 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
1106 Omit needless casts involving void * pointers and allocation.
1107 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
1108 as the former is more robust if P's type is changed.
1109 Prefer xzalloc to xmalloc + memset 0.
1110 Simplify malloc-or-realloc to realloc.
1111 Don't worry about xmalloc returning a null pointer.
1112 Prefer xstrdup to xmalloc + strcpy.
1113 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
1115 * keyboard.c (apply_modifiers_uncached): Prefer local array to
1116 alloca of a constant.
1118 2012-07-05 Eli Zaretskii <eliz@gnu.org>
1120 * xdisp.c (display_line): Fix horizontal pixel coordinates when
1121 hscroll is larger than the line width. Fixes long and futile
1122 looping inside extend_face_to_end_of_line (on a TTY) producing
1123 glyphs that are not needed and thrown away.
1125 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
1127 * marker.c (set_marker_restricted_both): Simplify by using
1130 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>

1141 followed by gtk_box_set_homogeneous (Bug#11768).
1142 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
1143 (update_theme_scrollbar_width, xg_create_scroll_bar):
1144 Use gtk_scrollbar_new (Bug#11768).
1145 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
1146 (is_box_type): New function (Bug#11768).
1147 (xg_tool_item_stale_p): Call is_box_type.
1148 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
1149 with default display (Bug#11768).

1153 * xdisp.c (window_hscroll_limited): New function.
1154 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
1155 coordinates when window's hscroll is set to insanely large
1158 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
1160 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

1221 * fileio.c (time_error_value): Check the right error number.
1222 Problem reported by Troels Nielsen in
1223 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.

1227 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
1228 This should be fixed in a better way; see Eli Zaretskii in
1229 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
1230 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
1232 * fileio.c (time_error_value): Rename from special_mtime.
1233 The old name's problems were noted by Eli Zaretskii in
1234 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
1236 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
1237 This variable's comment says Emacs needs at least one GDB-visible
1238 symbol of type enum pvec_type, to work around GDB problems.
1239 The symbol's value doesn't matter.
1241 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
1242 that causes compilation to fail on pre-C99 compilers.
1244 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
1246 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

1259 (PSEUDOVECTOR_SIZE_BITS): New constant.
1260 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
1261 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to

1269 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
1270 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
1271 (sweep_vectors): Use it. Use local var `total_bytes' instead of
1272 abusing vector->header.next.nbytes.
1273 (live_vector_p): Use PVEC_TYPE.
1274 (mark_object): Adapt code to extract pvectype. Use switch.
1276 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1278 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
1279 Tighten new eassert a bit.
1281 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
1283 Fix compilation with --enable-gcc-warnings and -O1
1285 * doprnt.c (doprnt): Change type of tem to int, initialize
1286 to avoid compiler warning. Add eassert.
1287 * search.c (simple_search): Initialize match_byte to avoid
1288 compiler warning. Add eassert.
1290 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1292 Avoid weird behavior with large horizontal scrolls.
1293 Without this change, for example, large hscroll values would
1294 mess up Emacs's display on Fedora 15 x86, presumably due to
1295 overflows in int calculations in the display code.
1296 Also, if buffers had long lines, Emacs would freeze.
1297 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
1298 (set_window_hscroll): New function, containing the old guts of
1299 Fset_window_hscroll. Return the clipped value.
1300 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
1301 This avoids the need to check against PTRDIFF_MAX.
1303 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
1305 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>

1309 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1311 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
1312 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
1313 since GCC 4.4.6 issues a bogus warning for them.
1315 Fix bugs in file timestamp newness comparisons.
1316 * fileio.c (Ffile_newer_than_file_p):
1317 * lread.c (Fload): Use full timestamp resolution of files,
1318 not just the 1-second resolution, so that files that are only
1319 slightly newer still count as newer.
1320 * fileio.c (Ffile_newer_than_file_p): Don't assume file
1321 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
1323 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
1325 * fileio.c: Improve handling of file time marker. (Bug#11852)
1326 (special_mtime): New function.
1327 (Finsert_file_contents, Fverify_visited_file_modtime):
1328 Use it to set special mtime values consistently.
1330 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
1332 * fileio.c (Finsert_file_contents): Properly handle st_mtime
1333 marker for non-existing file. (Bug#11852)
1335 2012-07-03 Glenn Morris <rgm@gnu.org>
1337 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
1338 and did not make it into globals.h).
1340 2012-07-03 Tom Tromey <tromey@redhat.com>

1378 2012-07-03 Glenn Morris <rgm@gnu.org>
1380 * lisp.h (Frandom): Make it visible to C.
1381 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
1382 buffer for invisible buffers. (Bug#1229)

1386 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
1387 values which aren't power of 2.
1388 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro. Verify
1389 it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
1392 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
1394 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.

1400 * alloc.c (allocate_vector_block): Remove redundant
1401 calls to mallopt if DOUG_LEA_MALLOC is defined.
1402 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
1403 avoid calls to mallopt if zero_vector is returned.
1405 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
1407 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
1408 is enabled, avoid dereferencing NULL current_sblock if
1411 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
1413 Cleanup basic buffer management.
1414 * buffer.h (struct buffer): Change layout to use generic vector
1415 marking code. Fix some comments. Change type of 'clip_changed'
1416 to bitfield. Remove unused #ifndef old.
1417 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
1418 (GET_OVERLAYS_AT): Fix indentation.
1419 (for_each_per_buffer_object_at): New macro.
1420 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
1421 (Fbuffer_local_variables): Use it.
1422 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
1423 * alloc.c (allocate_buffer): Adjust to match new layout of
1424 struct buffer. Fix comment.
1425 (mark_overlay): New function.
1426 (mark_buffer): Use it. Use mark_vectorlike to mark normal
1427 Lisp area of struct buffer.
1428 (mark_object): Use it. Adjust marking of misc objects
1429 and related comments.
1431 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
1433 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
1434 wrapper that is not needed because the wrapped code is a no-op (zero
1435 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
1436 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
1438 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
1440 * alloc.c (mark_buffer): Simplify. Remove prototype.
1441 (mark_object): Add comment. Reorganize marking of vector-like
1442 objects. Use CHECK_LIVE for all vector-like objects except buffers
1443 and subroutines when GC_CHECK_MARKED_OBJECTS is defined. Avoid
1444 redundant calls to mark_vectorlike for bool vectors.
1446 2012-06-30 Glenn Morris <rgm@gnu.org>
1448 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
1450 * epaths.in (PATH_SITELOADSEARCH): New.
1451 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
1452 This is rather than relying on --enable-locallisppath elements
1453 having "site-lisp" in their names. (Bug#10208#25, 11658)
1455 2012-06-30 Eli Zaretskii <eliz@gnu.org>
1457 * w32proc.c (sys_select): Accept and ignore one more argument.
1459 * w32.c (emacs_gnutls_pull): Call select with one more argument.
1461 * sysselect.h [DOS_NT]: Don't include sys/select.h.
1462 (pselect) [!MS_DOS]: Redirect to sys_select.
1464 * sysdep.c: Don't include dos.h and dosfns.h.
1466 * process.c (sys_select):
1467 * msdos.c (sys_select): Accept one more argument and ignore it.
1469 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
1470 adapt data types and code to that.
1473 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
1474 which clashes with the gnulib function of the same name.
1476 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
1478 * font.c (font_style_to_value, font_style_symbolic)
1479 (font_prop_validate_style): Add type checks for values in
1482 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
1484 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
1487 2012-06-29 Eli Zaretskii <eliz@gnu.org>
1489 * xdisp.c (try_window_id): Undo last change.
1491 * w32.c (getwd): Adjust commentary about startup_dir.
1492 (init_environment): Always call sys_access, even in non-MSVC
1493 builds. Don't chdir to the directory of the Emacs executable.
1494 This undoes code from 1997 which was justified by the need to
1495 "avoid conflicts when removing and renaming directories". But its
1496 downside was that every relative file name was being interpreted
1497 relative to the directory of the Emacs executable, which can never
1498 be TRT. In particular, it broke sys_access when called with
1499 relative file names.
1500 (sys_access): Map GetLastError to errno.
1502 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
1504 * window.h (struct window): Change type of 'fringes_outside_margins'
1505 to bitfield. Fix comment. Adjust users accordingly.
1506 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
1508 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
1511 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
1513 * gnutls.c (emacs_gnutls_handshake):
1514 Add QUIT to make the loop interruptible.
1516 2012-06-29 Glenn Morris <rgm@gnu.org>
1518 * charset.c (init_charset): Make lack of etc/charsets fatal.
1520 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
1522 * editfns.c (region_limit): Fix type mismatch.
1524 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
1526 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
1527 undefined. Convert from xassert to eassert.
1528 * nsmenu.m: Convert from xassert to eassert.
1529 * nsterm.m: Likewise.
1531 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>
1533 * editfns.c (region_limit): Clip to narrowing (bug#11770).
1535 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
1537 Avoid integer overflow on scroll-left and scroll-right.
1538 * window.c (HSCROLL_MAX): New macro.
1539 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
1540 overflow when requested scroll falls outside ptrdiff_t range.
1542 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
1544 * window.h (struct window): Change type of 'hscroll',
1545 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
1546 'last_modified' and 'last_overlay_modified' to EMACS_INT.
1547 Adjust users accordingly.
1548 * xdisp.c (try_cursor_movement): Replace type check with eassert.
1549 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
1550 from EMACS_INT to ptrdiff_t.
1551 (make_window): Omit redundant initialization.
1553 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
1555 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
1557 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
1559 * window.h (struct window): Change type of 'use_time' and
1560 'sequence_number' from Lisp_Object to int.
1561 * frame.c (make_frame): Adjust users accordingly.
1562 * print.c (print_object): Likewise.
1563 * window.c (select_window, Fwindow_use_time, make_parent_window)

1569 enabled with --enable-checking=[all,glyphs] configure option.
1570 Fix GLYPH_DEBUG usage assuming that it may be undefined,
1571 adjust comments accordingly.

1620 * alloc.c (allocate_string_data): Remove dead code.
1621 * xsettings.c (XSETTINGS_FONT_NAME): Move under HAVE_XFT to
1622 avoid GCC warning about unused macro.
1624 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
1626 * alloc.c (allocate_string): Omit intervals initialization.
1627 * alloc.c (make_uninit_multibyte_string): Initialize intervals
1628 as in make_pure_string and make_pure_c_string.
1630 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
1632 * alloc.c (allocate_string): Fix last change.
1634 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>

1647 2012-06-26 John Wiegley <johnw@newartisans.com>
1649 * unexmacosx.c (copy_data_segment): Add two section names used
1650 on Mac OS X Lion: __mod_init_func and __mod_term_func.

1653 when building with Clang.
1655 2012-06-26 Stefan Monnier <monnier@iro.umontreal.ca>

1659 2012-06-26 Eli Zaretskii <eliz@gnu.org>
1661 * s/ms-w32.h (strcasecmp, strncasecmp) [_MSC_VER]: Redirect to
1662 _stricmp and _strnicmp.
1663 (HAVE_STRCASECMP, HAVE_STRNCASECMP): Define to 1.
1665 2012-06-26 Dmitry Antipov <dmantipov@yandex.ru>
1667 * alloc.c (allocate_window): Zero out non-Lisp part of newly
1669 (allocate_process): Likewise for new process.

1680 * term.c (delete_tty): Remove redundant call to memset.
1682 2012-06-26 Dmitry Antipov <dmantipov@yandex.ru>
1684 * alloc.c: Remove build_string.
1685 * lisp.h: Define build_string as static inline. This provides
1686 a better opportunity to optimize away calls to strlen when the
1687 function is called with compile-time constant argument.
1688 * image.c (imagemagick_error): Convert to build_string.
1689 * w32proc.c (sys_spawnve): Likewise.
1690 * xterm.c (x_term_init): Likewise.
1692 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
1694 Use sprintf return value instead of invoking strlen on result.
1695 In the old days this wasn't portable, since some sprintf
1696 implementations returned char *. But they died out years ago and
1697 Emacs already assumes sprintf returns int.
1698 Similarly for float_to_string.
1699 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
1700 * ccl.c (ccl_driver):
1701 * character.c (string_escape_byte8):

1704 * print.c (print_object):
1705 * xdisp.c (message_dolog):
1706 * xfns.c (syms_of_xfns):
1707 Use sprintf or float_to_string result to avoid need to call strlen.
1708 * data.c (Fnumber_to_string):
1709 Use make_unibyte_string, since the string must be ASCII.
1710 * lisp.h, print.c (float_to_string): Now returns int length.
1711 * term.c (produce_glyphless_glyph):
1712 Use sprintf result rather than recomputing it.
1714 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
1715 * Makefile.in (ALL_CFLAGS):
1716 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
1717 * gmalloc.c, regex.c: Include <config.h> unconditionally.
1719 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
1721 * dispextern.h (xstrcasecmp): Define to library function
1722 strcasecmp if available.
1723 * xfaces.c: Do not use xstrcasecmp if strcasecmp is available.
1725 2012-06-25 Andreas Schwab <schwab@linux-m68k.org>
1727 * keyboard.c (menu_bar_items, menu_bar_item, read_key_sequence):

1738 2012-06-25 Paul Eggert <eggert@cs.ucla.edu>
1740 * gtkutil.c (get_utf8_string): Remove redundant assignment.
1741 sprintf already null-terminates its output.
1743 * xfns.c (x_window): Remove redundant cast.
1745 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
1747 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
1748 `const char *' to `char *' to avoid compiler warning.
1750 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
1752 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
1753 instead of truncating it to 63 (admittedly a generous limit).
1755 * process.c: Fix spelling and caps in comments.
1757 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
1759 * emacs.c (setpgrp): Remove definition, unused.

1769 (SYSTIME_H): Add nt/inc/sys/time.h.
1771 * systime.h [WINDOWSNT]: Include sys/time.h.
1773 * s/ms-w32.h (struct timespec): Definition moved from
1774 nt/inc/sys/time.h. Suggested by Paul Eggert <eggert@cs.ucla.edu>.
1776 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>

1804 No need for separate decl merely because of _Noreturn.
1805 * sound.c (sound_warning, parse_sound):
1806 Remove unnecessary forward decls.
1808 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
1810 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
1811 * lisp.h (WAIT_READING_MAX): New macro.
1812 * dispnew.c (Fsleep_for, sit_for):
1813 * keyboard.c (kbd_buffer_get_event):
1814 * process.c (Faccept_process_output):
1815 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
1816 This improves on the previous patch, which introduced a bug
1817 when time_t is unsigned and as wide as intmax_t.
1818 See <http://bugs.gnu.org/9000#51>.
1820 2012-06-23 Eli Zaretskii <eliz@gnu.org>
1822 * dispnew.c (sit_for, Fsleep_for):
1823 * keyboard.c (kbd_buffer_get_event):

1825 comparing a 32-bit time_t with a 64-bit INTMAX_MAX.
1827 2012-06-23 Juanma Barranquero <lekktu@gmail.com>
1829 * makefile.w32-in: Update dependencies.
1831 * w32.c (ltime): Add return type and declare static.
1832 (w32_get_internal_run_time): Remove usused variable `time_100ns'.
1834 2012-06-23 Paul Eggert <eggert@cs.ucla.edu>
1836 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
1837 Privately reported by Herbert J. Skuhra.
1838 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
1840 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
1841 not make_lisp_timeval, when the argument is of type EMACS_TIME.
1843 2012-06-23 Eli Zaretskii <eliz@gnu.org>
1845 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
1846 last argument of make_unibyte_string.
1848 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
1849 language ID in the event parameters.
1851 * w32term.c (w32_read_socket): Put the new keyboard codepage into
1852 event.code, not the obscure "character set ID".
1854 2012-06-23 Chong Yidong <cyd@gnu.org>
1856 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.
1858 2012-06-23 Eli Zaretskii <eliz@gnu.org>
1860 Fix the MS-Windows build broken by 2012-06-22T21:17:42Z!eggert@cs.ucla.edu.
1861 * w32.c (fdutimens): New function.
1863 * w32proc.c (sys_select): Adapt to change in the EMACS_TIME type.
1865 * s/ms-w32.h (pselect): Redirect to sys_select.
1867 * sysselect.h [WINDOWSNT]: Don't include sys/select.h.

1875 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.
1876 Privately reported by Herbert J. Skuhra.

1883 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
1885 Support higher-resolution time stamps (Bug#9000).
1886 The time stamps are only nanosecond-resolution at the C level,
1887 since that's the best that any real-world system supports now.
1888 But they are picosecond-resolution at the Lisp level, as that's
1889 easy, and leaves room for future OS improvements.
1891 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
1894 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
1895 Don't get current time unless it's needed.
1897 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
1898 now provides it if it's absent.
1899 (start_atimer): Port to higher-res time stamps.
1900 Check for time stamp overflow. Don't get current time more
1901 often than is needed.
1903 * buffer.h (struct buffer): Buffer modtime now has high resolution.
1904 Include systime.h, not time.h.
1905 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
1907 * dired.c: Include stat-time.h.
1908 (Ffile-attributes): File times now have higher resolution.
1910 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
1911 (struct image): Timestamp now has higher resolution.
1913 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
1914 has at least microseconds now. All uses removed.
1915 (update_frame, update_single_window, update_window, update_frame_1)
1916 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
1918 * editfns.c (time_overflow): Now extern.

1930 * fileio.c: Include <stat-time.h>
1931 (Fcopy_file): Copy higher-resolution time stamps.
1932 Prefer to set the time stamp via a file descriptor if that works.

1949 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
1950 Port to higher-resolution time stamps. Do not assume time_t is signed.
1951 (decode_timer): New function. Timers are now vectors of length 9,
1952 not 8, to accommodate the picosecond component.
1953 (timer_check_2): Use it.
1955 * nsterm.m (select_timeout, timeval_subtract): Remove.
1956 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
1957 as they're a bit more accurate and handle overflow better.

1959 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
1960 * nsterm.h (ns_select): Adjust prototype.
1962 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes

1964 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
1966 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
1968 * lisp.h (time_overflow): New decl.

1982 (Fprocess_attributes): Now generates ns-resolution time stamps.
1984 * sysdep.c: Include utimens.h. Don't include utime.h
1985 or worry about struct utimbuf; gnulib does that for us now.

1988 (set_file_times): Now sets ns-resolution time stamps.
1989 New arg FD; all uses changed.

1992 Now returns ns-resolution time stamp. All uses changed.
1993 Check for time stamp overflow.
1995 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
1996 provides a substitute now.
1998 * systime.h: Include timespec.h rather than sys/time.h and time.h,
1999 since it guarantees struct timespec.
2000 (EMACS_TIME): Now struct timespec, so that we can support
2001 ns-resolution time stamps.
2002 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
2003 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
2004 (EMACS_USECS): Remove.
2005 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
2006 so multiply the arg by 1000 before storing it.
2007 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
2009 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):

2016 (make_timeval, make_lisp_time, decode_time_components): New decls.
2017 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in

2019 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
2020 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.

2031 (w32_get_internal_run_time):
2032 Port to higher-resolution Emacs time stamps.

2047 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
2048 (timeval_subtract): Remove; no longer needed.
2049 (XTflash, XTring_bell, x_wait_for_event):
2050 Port to ns-resolution time stamps. Don't assume time_t is signed.

2056 2012-06-22 Eli Zaretskii <eliz@gnu.org>
2058 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
2059 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
2060 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
2061 staticidx goes up to 1597 out of 1600 = 0x640.)
2063 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
2065 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
2066 Otherwise, the umask might be mistakenly 0 while handling input signals.

2111 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
2112 gets killed during executing of this function (Bug#11665).
2113 Try to always return Qt when the buffer has been actually killed.
2114 (Vkill_buffer_query_functions): In doc-string say that functions
2115 run by this hook should not change the current buffer.
2117 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
2119 Fix recently-introduced process.c problems found by static checking.

2140 This removes the need for CHECK.
2141 (CHECK): Remove. Its comments about always evaluating its
2142 argument were confusing, as 'eassert' typically does not evaluate
2145 * coding.c (produce_chars): Use ptrdiff_t, not int.
2147 * xterm.c (x_draw_underwave): Check for integer overflow.
2148 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

2334 as the union type is for debugging, not for production.
2335 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
2336 Use an inline function on all platforms when using the union type,
2337 since this is simpler and 'static inline' can be used portably

2479 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
2481 * doprnt.c (doprnt): Truncate multibyte char correctly.
2482 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
2483 would mishandle a string argument "Xc" if X was a multibyte
2484 character of length 2: it would truncate after X's first byte
2485 rather than including all of X.
2487 2012-06-06 Chong Yidong <cyd@gnu.org>
2489 * buffer.c (word_wrap): Doc fix.

2538 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
2539 Convert pctcpu and pctmem to Lisp float properly.
2540 Let the compiler fold better, as 100.0/0x8000 is exact.
2542 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
2544 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
2547 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
2549 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
2551 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
2553 For a 'struct window', replace some Lisp_Object fields to
2554 bitfields where appropriate, remove unused fields.
2555 * window.h (struct window): Remove unused 'last_mark_x' and
2556 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
2557 change it's type from Lisp_Object to bitfield.
2558 Change type of 'force_start', 'optional_new_start',
2559 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
2560 fields from Lisp_Object to bitfield. Adjust users accordingly.
2562 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
2564 Pacify gcc -Wdouble-precision when using Xaw.
2565 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
2566 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
2567 Use 'float' consistently, rather than 'float' in most places
2568 and 'double' in a couple of places.
2570 2012-05-31 Eli Zaretskii <eliz@gnu.org>
2572 * xdisp.c (handle_stop): Detect whether we have overlay strings
2573 loaded by testing it->current.overlay_string_index to be
2574 non-negative, instead of checking whether n_overlay_strings is
2575 positive. (Bug#11587)
2577 2012-05-31 Chong Yidong <cyd@gnu.org>
2579 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
2581 * doc.c (Fsubstitute_command_keys): Doc fix.
2583 2012-05-31 Eli Zaretskii <eliz@gnu.org>
2585 * search.c (search_buffer): Remove calls to
2586 r_alloc_inhibit_buffer_relocation, as it is now called by
2587 maybe_unify_char, which was the cause of relocation of buffer text
2590 2012-05-31 Eli Zaretskii <eliz@gnu.org>
2592 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
2593 for the duration of call to load_charset, to avoid problems with
2594 callers of maybe_unify_char that access buffer text through C
2597 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
2598 decrement the inhibition flag, instead of just setting or
2601 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
2603 Remove obsolete '#define static' cruft.
2604 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
2605 This #undef was "temporary" in 2000; it is no longer needed
2606 now that '#define static' has gone away.
2607 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
2608 (gray_bitmap_bits): Remove; no longer needed.
2609 All uses replaced with definiens.
2610 * xterm.c: Include "bitmaps/gray.xbm".
2612 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
2614 Clean up __executable_start, monstartup when --enable-profiling.
2615 The following changes affect the code only when profiling.
2616 * dispnew.c (__executable_start): Rename from safe_bcopy.
2617 Define only on platforms that need it.
2618 * emacs.c: Include <sys/gmon.h> when profiling.
2619 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
2620 (__executable_start): Remove decl, since lisp.h does it now.
2621 (safe_bcopy): Remove decl; no longer has that name.
2622 (main): Coalesce #if into single bit of code, for simplicity.
2623 Cast pointers to uintptr_t, since standard libraries want integers

2652 Do not create empty overlays with the evaporate property (Bug#9642).
2653 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
2654 Bug#9642, but explicitly check that the buffer the overlay would
2655 be moved to is live and rearrange lines to make sure that errors
2656 will not put the overlay in an inconsistent state.
2657 (Fdelete_overlay): Cosmetics.
2659 2012-05-28 Eli Zaretskii <eliz@gnu.org>
2661 * w32term.c (my_bring_window_to_top): New function.
2662 (x_raise_frame): Use handle returned by DeferWindowPos, which
2663 could be different from the original one.

2667 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
2668 by calling BringWindowToTop.
2670 * w32term.h (WM_EMACS_BRINGTOTOP): New message.
2671 (WM_EMACS_END): Increase by one.
2673 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
2675 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
2676 This avoids undefined behavior that might cause the eassert
2677 to not catch an out-of-range value.
2679 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
2681 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

2691 when referring to sectname field in printf format.
2693 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
2695 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
2696 Only r_alloc_inhibit_buffer_relocation needed to be added;
2697 the others were already declared.
2699 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
2700 before checking whether it's out of range. Put the check inside
2702 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
2704 2012-05-27 Ken Brown <kbrown@cornell.edu>
2706 * callproc.c (Fcall_process): Restore a line that was accidentally
2707 commented out in the 2011-02-13 change (bug#11547).

2712 defined on ralloc.c.
2714 * buffer.c [REL_ALLOC]: Remove prototypes of

2716 they are now on lisp.h.
2718 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
2720 * search.c (search_buffer): Use it to inhibit relocation of buffer
2721 text while re_search_2 is doing its job, because re_search_2 is
2722 passed C pointers to buffer text. (Bug#11519)
2724 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
2727 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
2728 state after an additional call to move_it_in_display_line_to, keep
2729 the values of it->max_ascent and it->max_descent found for the
2731 (pos_visible_p): Revert the comparison against bottom_y to what it
2732 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
2735 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
2737 Fix coding-related core dumps with gcc -ftrapv.
2738 The code was computing A - B, where A and B are pointers, and B is
2739 random garbage. This can lead to core dumps on platforms that
2740 have special pointer registers, and it also leads to core dumps on
2741 x86-64 when compiled with gcc -ftrapv. The fix is to compute
2742 A - B only when B is initialized properly.
2743 * coding.c (coding_set_source, coding_set_destination): Return void.
2744 (coding_change_source, coding_change_destinations): New functions,
2745 with the old behaviors of coding_set_source and coding_set_destination.
2746 All callers that need an offset changed to use these new functions.

2750 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
2752 2012-05-26 Eli Zaretskii <eliz@gnu.org>

2755 * xdisp.c (draw_row_with_mouse_face):
2756 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
2758 * w32console.c: Include window.h.
2759 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
2761 (initialize_w32_display): Initialize mouse-highlight data.
2763 * w32inevt.c: Include termchar.h and window.h.
2764 (do_mouse_event): Support mouse-autoselect-window. When the mouse
2765 moves, call note_mouse_highlight. If help_echo changed, call
2766 gen_help_event to produce help-echo message in the echo area.
2767 Call clear_mouse_face if mouse_face_hidden is set in the mouse
2770 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
2772 * lread.c (read1): Simplify slightly to avoid an overflow warning
2773 with GCC 4.7.0 on x86-64.
2775 2012-05-26 Eli Zaretskii <eliz@gnu.org>
2777 * bidi.c (bidi_mirror_char): Revert last change: an int is
2778 definitely wide enough here.

2790 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
2792 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2793 (allocate_pseudovector):
2794 Use int, not EMACS_INT, where int is wide enough.
2795 (inhibit_garbage_collection, Fgarbage_collect):
2796 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
2797 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
2798 int might not be wide enough.
2799 (bidi_cache_search, bidi_cache_find, bidi_init_it)
2800 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)

2802 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
2803 (bidi_level_of_next_char, bidi_move_to_visually_next):
2804 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2805 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
2806 (Fkill_buffer, Fset_buffer_major_mode)
2807 (advance_to_char_boundary, Fbuffer_swap_text)
2808 (Fset_buffer_multibyte, overlays_at, overlays_in)
2809 (overlay_touches_p, struct sortvec, record_overlay_string)
2810 (overlay_strings, recenter_overlay_lists)

2813 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
2814 (Foverlay_recenter, last_overlay_modification_hooks_used)
2815 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
2816 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2817 (validate_region): Omit unnecessary test for b <= e,
2818 since that's guaranteed by the previous test.
2819 (adjust_overlays_for_delete): Avoid pos + length overflow.
2820 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
2821 (report_overlay_modification):

2823 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
2824 Omit pointer cast, which isn't needed anyway, and doesn't work
2825 after the EMACS_INT -> ptrdiff_t change.
2826 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
2827 * buffer.h: Adjust decls to match defn changes elsewhere.
2828 (struct buffer_text, struct buffer):
2829 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2830 Use EMACS_INT, not int, where int might not be wide enough.
2831 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
2832 not int, to avoid needless 32-bit limit on 64-bit hosts.
2833 (exec_byte_code): Use tighter memory-full test, one that checks
2834 for alloca overflow. Don't compute the address of the object just
2835 before an array, as that's not portable. Use EMACS_INT, not
2836 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
2837 * callint.c (Fcall_interactively):
2838 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
2839 * callproc.c (call_process_kill, Fcall_process):
2840 Don't assume pid_t fits into an Emacs fixnum.
2841 (call_process_cleanup, Fcall_process, child_setup):

2851 (casify_object): Avoid integer overflow when overallocating buffer.
2852 * casetab.c (set_identity, shuffle): Prefer int to unsigned when

2855 * category.h (CATEGORYP): Don't assume arg is nonnegative.
2856 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
2857 integers are now checked earlier. All uses replaced with XINT.
2859 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
2860 For CCL_MapSingle, check that content and value are in int range.
2861 (ccl_driver, Fregister_code_conversion_map):
2862 Check that Vcode_version_map_vector is a vector.
2863 (resolve_symbol_ccl_program): Check that vector header is in range.
2864 Always copy the vector, so that we can check its contents reliably
2865 now rather than having to recheck each instruction as it's being
2866 executed. Check that vector words fit in 'int'.
2867 (ccl_get_compiled_code, Fregister_ccl_program)
2868 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
2869 program indexes, to avoid needless 32-bit limit on 64-bit hosts.

2871 contents are in range.
2872 (Fccl_execute_on_string): Check that status is in range.

2874 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):

2898 that's not true for gb10830 4-byte on a 32-bit host. Allow
2899 invalid_code to be a cons, for the same reason. Require code_offset
2900 to be a character. Avoid int overflow if max_char is close

2903 this is intended anyway and avoids some undefined behavior.

2905 INDEX_TO_CODE_POINT, as that's what it expects.
2906 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.

2910 integer-overflow issues.

2913 where the argument is EMACS_INT, and this behavior is not intended.
2914 * chartab.c (Fmake_char_table, Fset_char_table_range)
2915 (uniprop_get_decoder, uniprop_get_encoder):
2916 Don't assume fixnum fits in int.
2917 * cmds.c (move_point): New function, that does the gist of

2919 for integer overflow more accurately.

3546 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3547 (merge_faces): Use int, not EMACS_INT, where int is wide enough.
3548 * xfns.c (x_set_menu_bar_lines, x_set_tool_bar_lines, x_icon_verify)
3550 Check that fixnums are in proper range for system types.
3551 (Fx_create_frame, x_create_tip_frame, Fx_show_tip)
3552 (Fx_hide_tip, Fx_file_dialog, Fx_select_font):

3554 (Fx_change_window_property): Don't assume fixnums fit in int.
3555 * xfont.c (xfont_chars_supported):
3556 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.

3560 * xml.c (parse_region):
3561 * xrdb.c (magic_file_p):
3562 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

3564 (x_get_local_selection, x_reply_selection_request)
3565 (x_handle_selection_request, wait_for_property_change):
3566 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3567 (selection_data_to_lisp_data): Use short, not EMACS_INT, where
3568 short is wide enough.
3569 (x_send_client_event): Don't assume fixnum fits in int.
3570 * xterm.c (x_x_to_emacs_modifiers):
3571 Don't assume EMACS_INT overflows nicely into int.
3572 (x_emacs_to_x_modifiers): Use EMACS_INT, not int, because values
3574 (handle_one_xevent): NATNUMP can eval its arg twice.
3575 (x_connection_closed):
3576 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3577 * xterm.h: Adjust decls to match defn changes elsewhere.
3578 (struct scroll_bar): Use struct vectorlike_header
3579 rather than rolling our own approximation.
3580 (SCROLL_BAR_VEC_SIZE): Remove; not used.
3582 2012-05-25 Glenn Morris <rgm@gnu.org>
3584 * lisp.mk (lisp): Update for more files being compiled now.
3586 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>

3589 (read_pure): Remove var.
3590 (unreadpure): Remove function.
3591 (readevalloop): Don't call read_list with -1 flag.
3592 (read1, read_vector): Don't test read_pure any more.
3593 (read_list): Simplify.
3595 * fileio.c, character.h: Minor style tweaks.
3597 2012-05-24 Dmitry Antipov <dmantipov@yandex.ru>
3599 * window.h (clip_changed): Remove useless declaration.
3601 2012-05-22 Juanma Barranquero <lekktu@gmail.com>
3603 * makefile.w32-in: Follow-up to 2012-05-22T16:20:27Z!eggert@cs.ucla.edu.
3604 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
3606 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
3609 This directory predates autoconf and is no longer needed nowadays.
3610 Move its few remaining bits of functionality to where they're needed.
3611 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:
3612 * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:

3616 * lisp.h (USE_LSB_TAG):
3617 * mem-limits.h (EXCEEDS_LISP_PTR):
3618 Use VAL_MAX, not VALBITS, in #if.
3619 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
3620 (EMACS_UINT): Define unconditionally now.
3621 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
3622 (BITS_PER_EMACS_INT): New constants, replacing
3623 what used to be in config.h, but not useful in #if.
3624 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
3625 define them any more.
3626 (VAL_MAX): New macro.
3628 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
3629 BITS_PER_EMACS_INT, in #if.
3630 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
3631 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
3632 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
3633 * s/ms-w32.h (DATA_START):
3634 Move here from removed file m/intel386.h.
3635 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
3636 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
3638 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
3640 Assume C89 or later.
3641 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.

3648 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
3649 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
3650 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
3651 * xterm.c (input_signal_count): Assume volatile works.
3653 2012-05-21 Ken Brown <kbrown@cornell.edu>
3655 * xgselect.c (xg_select): Fix first argument in call to 'select'
3658 2012-05-20 Ken Brown <kbrown@cornell.edu>
3660 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
3661 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
3663 2012-05-19 Ken Brown <kbrown@cornell.edu>
3665 * xfns.c (x_in_use): Remove `static' qualifier.
3666 * xterm.h (x_in_use): Declare.
3667 * xgselect.c: Include xterm.h.
3668 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
3669 and `display_arg' (bug#9754).
3671 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
3673 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
3675 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
3676 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
3678 2012-05-18 Eli Zaretskii <eliz@gnu.org>
3680 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
3682 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
3683 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
3685 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
3686 reference to image_cache->refcount.
3687 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
3689 2012-05-17 Juri Linkov <juri@jurta.org>
3691 * search.c (Fword_search_regexp, Fword_search_backward)
3692 (Fword_search_forward, Fword_search_backward_lax)
3693 (Fword_search_forward_lax): Move functions to isearch.el
3694 (bug#10145, bug#11381).
3696 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
3698 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
3700 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
3702 * lread.c (init_obarray): Declare Qt and Qnil as special.
3704 2012-05-14 Glenn Morris <rgm@gnu.org>
3706 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
3707 Put "libexec" before "bin", for the sake of init_callproc_1.
3709 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
3711 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
3713 * unexaix.c: Port to more-recent AIX compilers.
3714 (report_error, report_error_1, make_hdr, copy_sym)
3715 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
3716 Make arguments const char *, not char *, to avoid violations of C
3717 standard and to fix some AIX warnings reported by Gilles Pion.
3719 2012-05-14 Eli Zaretskii <eliz@gnu.org>
3721 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
3722 already have overlays loaded.
3723 (handle_single_display_spec): Before returning without displaying
3724 fringe bitmap, synchronize the bidi iterator with the main display
3725 iterator, by calling iterate_out_of_display_property.
3726 (iterate_out_of_display_property): Detect buffer iteration by
3727 testing that it->string is a Lisp string.
3728 (get_next_display_element): When the current object is exhausted,
3729 and there's something on it->stack, call set_iterator_to_next to
3730 proceed with what's on the stack, instead of returning zero.
3731 (set_iterator_to_next): If called at the end of a Lisp string,
3732 proceed to consider_string_end without incrementing string
3733 position. Don't increment display vector index past the end of
3734 the display vector. (Bug#11417)
3735 (pos_visible_p): Don't report a position visible when move_it_to
3736 stopped at the last line of window, which happens to be scanned
3737 backwards by the bidi iteration. (Bug#11464)
3739 2012-05-14 Eli Zaretskii <eliz@gnu.org>
3741 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
3742 and right-margin display specs even if the spec is invalid or we
3743 are on a TTY, and thus unable to display on the fringes.
3744 That's because the text with the property will not be displayed anyway,
3745 so we need to signal to the caller that this is a "replacing"
3746 display spec. This fixes display when the spec is invalid or we
3749 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
3751 * unexaix.c (make_hdr): Fix typo in prototype.
3752 This bug broke the build on AIX. Problem reported by Gilles Pion.
3754 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
3756 * keyboard.c (kbd_buffer_get_event): Read special events also in
3757 batch mode. (Bug#11415)
3759 2012-05-12 Glenn Morris <rgm@gnu.org>
3761 * ns.mk: Update for ns_appbindir no longer having trailing "/".
3763 2012-05-12 Eli Zaretskii <eliz@gnu.org>
3765 * lisp.mk (lisp): Add newcomment.elc.
3767 2012-05-12 Glenn Morris <rgm@gnu.org>
3769 * Makefile.in (MKDIR_P): New, set by configure.
3770 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
3772 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
3774 Remove unused function hourglass_started.
3775 * dispextern.h (hourglass_started):
3776 * w32fns.c (hourglass_started):
3777 * xdisp.c (hourglass_started): Remove.
3779 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
3781 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
3782 Update dependencies.
3784 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
3786 * xgselect.c (xg_select): Put maxfds+1 into a var.
3787 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
3789 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
3791 2012-05-10 Dave Abrahams <dave@boostpro.com>
3793 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
3794 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
3796 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
3798 * dbusbind.c (xd_registered_buses): New internal Lisp object.
3799 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
3800 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
3801 Initialize xd_registered_buses.
3803 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
3805 Untag more efficiently if USE_LSB_TAG.
3806 This is based on a proposal by YAMAMOTO Mitsuharu in
3807 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
3808 For an admittedly artificial (nth 8000 longlist) benchmark on
3809 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
3810 Emacs's overall text size by 1%.
3811 * lisp.h (XUNTAG): New macro.
3812 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
3813 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
3814 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
3815 * eval.c (Fautoload):
3816 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
3817 * frame.h (XFRAME): Use XUNTAG.
3819 Port recent dbusbind.c changes to 32-bit --with-wide-int.
3820 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
3821 Remove unportable assumptions about print widths of types like
3823 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
3824 intptr_t when converting between pointer and integer, to avoid GCC
3825 warnings about wrong width.
3827 2012-05-09 Eli Zaretskii <eliz@gnu.org>
3829 * w32proc.c (new_child): Force Windows to reserve only 64KB of
3830 stack for each reader_thread, instead of defaulting to 8MB
3831 determined by the linker. This avoids failures in creating
3832 subprocesses on Windows 7, see the discussion in this thread:
3833 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
3835 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
3837 Fix up display of the *Minibuf-0* buffer in the mini window.
3838 * keyboard.c (read_char): Don't clear the echo area if there's no
3840 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
3841 contents of *Minibuf-0*) if there's no message displayed in its stead.
3843 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
3845 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
3848 2012-05-06 Chong Yidong <cyd@gnu.org>
3850 * lisp.mk (lisp): Update.
3852 2012-05-05 Jim Meyering <meyering@redhat.com>
3854 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
3856 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
3858 * data.c (PUT_ERROR): New macro.
3859 (syms_of_data): Use it. Add new error type `user-error'.
3860 * undo.c (user_error): New function.
3861 (Fprimitive_undo): Use it.
3862 * print.c (print_error_message): Adjust print style for `user-error'.
3863 * keyboard.c (user_error): New function.
3864 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
3866 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
3868 Do not limit current-time-string to years 1000..9999.
3869 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
3870 (Fcurrent_time_string): Support any year that is supported by the
3871 underlying localtime representation. Don't use asctime, as it
3872 has undefined behavior for years outside the range -999..9999.
3874 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
3876 Fix race conditions involving setenv, gmtime, localtime, asctime.
3877 Without this fix, interrupts could mess up code that uses these
3878 nonreentrant functions, since setting TZ invalidates existing
3879 tm_zone or tzname values, and since most of these functions return
3880 pointers to static storage.
3881 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
3882 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
3883 Grow the critical sections to include not just invoking
3884 localtime/gmtime, but also accessing these functions' results
3885 including their tm_zone values if any, and any related TZ setting.
3886 (format_time_string): Last arg is now struct tm *, not struct tm **,
3887 so that the struct tm is saved in the critical section.
3888 All callers changed. Simplify allocation of initial buffer, partly
3889 motivated by the fact that memory allocation needs to be outside
3890 the critical section.
3892 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
3894 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
3895 with RESET_INTERVAL.
3897 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
3898 Remove duplicated buffer name initialization.
3900 2012-05-02 Jim Meyering <jim@meyering.net>
3902 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
3904 * xfns.c (x_window): Use xstrdup (Bug#11375).
3906 2012-05-02 Eli Zaretskii <eliz@gnu.org>
3908 * xdisp.c (pos_visible_p): If already at a newline from the
3909 display string before the 'while' loop, don't walk back the glyphs
3910 from it3.glyph_row. Solves assertion violation when the display
3911 string begins with a newline (egg.el). (Bug#11367)
3913 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
3915 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
3918 2012-05-01 Glenn Morris <rgm@gnu.org>
3920 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
3921 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
3922 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
3923 All were removed before 23.1.
3925 * dispnew.c: Remove HAVE_LIBNCURSES test;
3926 it is always true on relevant platforms.
3928 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
3929 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
3931 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
3933 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
3935 * .gdbinit (xpr): Remove checks for no longer existing misc types.
3936 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
3939 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
3941 Do not avoid creating empty evaporating overlays (Bug#9642).
3942 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
3943 That is, do not delete an evaporating overlay if it becomes
3944 empty after its bounds are adjusted to fit within its buffer.
3945 This fix caused other problems, and I'm reverting it until we get
3946 to the bottom of them.
3948 2012-04-27 Chong Yidong <cyd@gnu.org>
3950 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
3952 2012-04-27 Eli Zaretskii <eliz@gnu.org>
3954 * xdisp.c (pos_visible_p): If the window start position is beyond
3955 ZV, start the display from buffer beginning. Prevents assertion
3956 violation in init_iterator when the minibuffer window is scrolled
3959 * window.c (window_scroll_pixel_based): Likewise.
3961 2012-04-27 Chong Yidong <cyd@gnu.org>
3963 * keymap.c (where_is_internal): Doc fix (Bug#10872).
3965 2012-04-27 Glenn Morris <rgm@gnu.org>
3967 * fileio.c (Fcopy_file, Fset_file_selinux_context):
3968 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
3970 2012-04-27 Eli Zaretskii <eliz@gnu.org>
3972 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
3973 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
3975 2012-04-26 Eli Zaretskii <eliz@gnu.org>
3977 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
3978 display element, check also the underlying string or buffer
3979 character. (Bug#11341)
3981 * w32menu.c: Include w32heap.h.
3982 (add_menu_item): If the call to AppendMenuW (via
3983 unicode_append_menu) fails, disable Unicode menus only if we are
3984 running on Windows 9X/Me.
3986 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
3988 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
3989 (xgetint): Add missing shift for LSB tags.
3991 2012-04-24 Martin Rudalics <rudalics@gmx.at>
3993 * keyboard.c (read_char): Don't wipe echo area for select window
3994 events: These might get delayed via `mouse-autoselect-window'

4007 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
4009 Do not create empty overlays with the evaporate property (Bug#9642).
4010 * buffer.c (Fmove_overlay): Delete an evaporating overlay
4011 if it becomes empty after its bounds are adjusted to fit within
4012 its buffer. Without this fix, in a nonempty buffer (let ((o
4013 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
4014 yields an empty overlay that has the evaporate property, which is
4015 not supposed to happen.

4119 since the two debugging options are incompatible.
4120 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
4122 (mem_init, mem_insert, mem_insert_fixup):
4123 Define if GC_MARK_STACK || GC_MALLOC_CHECK.

4155 (print_object): Check for cycles even when print-circle is nil and
4156 print-gensym is t, but only check print_depth if print-circle is nil.
4158 2012-04-20 Chong Yidong <cyd@gnu.org>
4160 * process.c (wait_reading_process_output): If EIO occurs on a pty,

4216 New extern decls, to avoid calling undeclared functions.
4217 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
4218 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
4219 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
4220 (NEED_MEM_INSERT): New macro.
4221 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
4222 Remove one incorrect comment and fix another.

4236 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
4237 Remove decls. This fixes an "It stinks!".

4241 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
4243 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

4260 Remove definition of GC_MARK_STACK, since the default now works.
4261 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:

4263 no longer the default.
4264 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
4266 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

4289 2012-04-11 Daniel Colascione <dancol@dancol.org>
4291 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
4292 against is gone. It's better to use vfork now so that when Cygwin
4293 gains a new, working vfork, we use it automatically (bug#10398).
4295 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

4350 2012-04-09 Eli Zaretskii <eliz@gnu.org>
4352 * xdisp.c (set_cursor_from_row): If the display string appears in
4353 the buffer at position that is closer to point than the position
4354 after the display string, display the cursor on the first glyph of
4355 the display string. Fixes cursor display when a 'display' text
4356 property immediately follows invisible text. (Bug#11094)
4358 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
4360 composite.c: use 'double' consistently
4361 * composite.c (get_composition_id): Use 'double' consistently
4362 instead of converting 'float' to 'double' and vice versa; this is
4363 easier to understand and avoids a GCC warning.
4365 2012-04-09 Glenn Morris <rgm@gnu.org>
4367 * Makefile.in: Generate leim-list with bootstrap-emacs, in

4412 [!WINDOWSNT]: New macros.
4413 (init_libxml2_functions, libxml2_loaded_p): New functions.
4414 (parse_region): Call fn_xmlCheckVersion instead of using the macro
4415 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
4416 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
4417 Calls xmlCleanupParser only if libxml2 was loaded (or statically
4419 (Flibxml_parse_html_region, Flibxml_parse_xml_region):

4437 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
4438 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
4439 about subtle differences between FETCH_CHAR* and STRING_CHAR*
4440 macros related to unification of CJK characters. For the details,

4442 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
4444 2012-04-04 Chong Yidong <cyd@gnu.org>
4446 * keyboard.c (Vdelayed_warnings_list): Doc fix.
4448 2012-04-01 Eli Zaretskii <eliz@gnu.org>
4450 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
4451 instead of alloca. (Bug#11138)
4453 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
4455 * w32menu.c (is_simple_dialog): Properly check lisp types.
4458 2012-03-31 Eli Zaretskii <eliz@gnu.org>
4460 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
4461 position we get to after a call to move_it_to fails the
4462 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
4463 only if we wind up in a string from display property. (Bug#11063)
4465 * window.c (Fdelete_other_windows_internal): Invalidate the row
4466 and column information about mouse highlight, so that redisplay
4467 restores it after reallocating the glyph matrices. (Bug#7464)
4469 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
4470 string comes from a `display' text property, use the buffer
4471 position of that property as if we actually saw that position in
4473 (move_it_by_lines): Remove the assertion that
4474 "it->current_x == 0 && it->hpos == 0" which can be legitimately
4475 violated when there's a before-string at the beginning of a line.
4478 2012-03-30 Eli Zaretskii <eliz@gnu.org>
4480 * xdisp.c (append_space_for_newline): If the default face was
4481 remapped, use the remapped face for the appended newline.
4482 (extend_face_to_end_of_line): Use the remapped default face for
4483 extending the face to the end of the line.
4484 (display_line): Call extend_face_to_end_of_line when the default
4485 face was remapped. (Bug#11068)
4487 2012-03-29 Eli Zaretskii <eliz@gnu.org>
4489 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
4491 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
4493 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
4495 2012-03-27 Glenn Morris <rgm@gnu.org>
4497 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
4500 2012-03-26 Kenichi Handa <handa@m17n.org>
4502 * dispextern.h (struct glyph): Fix previous change. Change the
4503 bit length of glyphless.ch to 25 (Bug#11082).
4505 2012-03-26 Chong Yidong <cyd@gnu.org>
4507 * keyboard.c (Vselection_inhibit_update_commands): New variable.
4508 (command_loop_1): Use it; inhibit selection update for
4509 handle-select-window too (Bug#8996).
4511 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
4513 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
4515 2012-03-25 Kenichi Handa <handa@m17n.org>
4517 * dispextern.h (struct glyph): Change the bit length of
4518 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
4520 2012-03-24 Eli Zaretskii <eliz@gnu.org>
4522 * s/ms-w32.h (tzname): Include time.h before redirecting to
4523 _tzname. Fixes the MSVC build. (Bug#9960)
4525 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
4527 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
4530 * xterm.c (XTread_socket): Only modify handling_signal if
4531 !SYNC_INPUT. (Bug#11080)
4533 2012-03-23 Eli Zaretskii <eliz@gnu.org>
4535 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
4536 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
4537 when fetching a multibyte character consumes more bytes than
4538 CHAR_BYTES returns, due to unification of CJK characters in
4539 string_char. (Bug#11073)
4541 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
4543 * process.c (wait_reading_process_output): Handle pty disconnect
4544 by refraining from sending oneself a SIGCHLD (bug#10933).
4546 2012-03-22 Chong Yidong <cyd@gnu.org>
4548 * dispextern.h (struct it): New member string_from_prefix_prop_p.
4550 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
4551 Mark string as coming from a prefix property.
4552 (handle_face_prop): Use default face for prefix strings (Bug#4281).
4553 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
4555 2012-03-21 Chong Yidong <cyd@gnu.org>
4557 * xfaces.c (Vface_remapping_alist): Doc fix.
4559 2012-03-20 Eli Zaretskii <eliz@gnu.org>
4561 * w32proc.c (Fw32_set_console_codepage)
4562 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
4565 2012-03-20 Chong Yidong <cyd@gnu.org>
4567 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
4568 to reflect default non-nil value of redisplay-dont-pause.
4570 2012-03-19 Kenichi Handa <handa@m17n.org>
4572 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
4573 it fit in a valid range (Bug#11003).
4575 2012-03-18 Eli Zaretskii <eliz@gnu.org>
4577 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
4578 that is not from display property, accept the row as a "cursor
4579 row" if one of the string's character has a non-nil `cursor'
4580 property. Fixes cursor positioning when there are newlines in
4581 overlay strings, e.g. in icomplete.el. (Bug#11035)
4583 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
4585 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
4587 2012-03-12 Chong Yidong <cyd@gnu.org>
4589 * eval.c (inhibit_lisp_code): Rename from
4590 inhibit_window_configuration_change_hook; move from window.c.
4592 * xfns.c (unwind_create_frame_1, Fx_create_frame):
4593 * window.c (run_window_configuration_change_hook)
4594 (syms_of_window): Callers changed.
4596 2012-03-11 Chong Yidong <cyd@gnu.org>
4598 * keymap.c (Fkey_description): Doc fix (Bug#9700).
4600 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).

4605 is visible (Bug#10955).
4607 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
4609 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
4611 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
4613 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
4614 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
4617 2012-03-03 Glenn Morris <rgm@gnu.org>
4619 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
4621 2012-03-02 Eli Zaretskii <eliz@gnu.org>
4623 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
4624 position past the first glyph_row that ends at ZV. (Bug#10902)
4625 (redisplay_window, next_element_from_string): Fix typos in
4627 (redisplay_window): Pass to move_it_vertically the margin in
4628 pixels, not in screen lines.
4630 2012-03-02 Glenn Morris <rgm@gnu.org>
4632 * buffer.c (buffer-list-update-hook): Doc fix.
4634 2012-02-29 Eli Zaretskii <eliz@gnu.org>
4636 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
4637 push_it before setting up the iterator for the first overlay
4638 string, even if we have an empty string loaded.
4639 (next_overlay_string): If there's an empty string on the iterator
4640 stack, pop the stack. (Bug#10903)
4642 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
4644 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
4645 Suggested by Stefan Monnier in
4646 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
4647 * alloc.c (widen_to_Lisp_Object): New static function.
4648 (mark_memory): Also mark Lisp_Objects by fetching pointer words
4649 and widening them to Lisp_Objects. This would work even if
4650 USE_LSB_TAG is defined and wide integers are used, which might
4651 happen in a future version of Emacs.
4653 2012-02-25 Chong Yidong <cyd@gnu.org>
4655 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
4658 * xselect.c (Fx_selection_exists_p): Doc fix.
4659 (x_clipboard_manager_save_all): Print an informative message
4660 before saving to clipboard manager.
4662 2012-02-24 Chong Yidong <cyd@gnu.org>
4664 * keyboard.c (process_special_events): Handle all X selection
4665 requests in kbd_buffer, not just the next one (Bug#8869).
4667 2012-02-23 Chong Yidong <cyd@gnu.org>
4669 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
4670 call when setting menu-bar-lines and tool-bar-lines parameters.
4671 (unwind_create_frame_1): New helper function.
4673 * window.c (inhibit_window_configuration_change_hook): New var.
4674 (run_window_configuration_change_hook): Obey it.
4675 (syms_of_window): Initialize it.
4677 2012-02-22 Chong Yidong <cyd@gnu.org>
4679 * xterm.c (x_draw_image_relief): Add missing type check for
4680 Vtool_bar_button_margin (Bug#10743).
4682 2012-02-21 Chong Yidong <cyd@gnu.org>
4684 * fileio.c (Vfile_name_handler_alist): Doc fix.
4686 * buffer.c (Fget_file_buffer): Protect against invalid file
4687 handler return value.
4689 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
4691 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
4692 when computing $valmask.
4694 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
4695 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
4696 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
4697 It's useless in that case, and it can cause problems on hosts
4698 that allocate halves of EMACS_INT values separately.
4699 Reported by Dan Horák. Diagnosed by Andreas Schwab in
4700 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
4701 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
4702 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
4703 it avoids undefined behavior on hosts where shifting right by more
4704 than the word width has undefined behavior.
4706 2012-02-19 Chong Yidong <cyd@gnu.org>
4708 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
4709 (Funhandled_file_name_directory, Ffile_name_as_directory)
4710 (Fdirectory_file_name, Fexpand_file_name)
4711 (Fsubstitute_in_file_name): Protect against invalid file handler
4712 return values (Bug#10845).
4714 2012-02-18 Eli Zaretskii <eliz@gnu.org>
4716 * .gdbinit (pitx): Fix incorrect references to fields of the
4719 2012-02-17 Chong Yidong <cyd@gnu.org>
4721 * syntax.c (Fscan_lists): Doc fix (Bug#10833).
4723 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
4725 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
4726 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
4728 2012-02-15 Chong Yidong <cyd@gnu.org>
4730 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
4731 marked as special. Also, starting docstrings with * is obsolete.
4733 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
4735 * gnutls.c (emacs_gnutls_write): Fix last change.
4737 2012-02-13 Lars Ingebrigtsen <larsi@gnus.org>

4742 2012-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
4744 * keymap.c (Fsingle_key_description): Handle char ranges.
4746 2012-02-12 Chong Yidong <cyd@gnu.org>
4748 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
4749 as that creates a dangerous corner case.
4751 * window.c (Fdelete_window_internal): Invalidate the mouse
4752 highlight (Bug#9904).
4754 2012-02-12 Glenn Morris <rgm@gnu.org>
4756 * xselect.c (Fx_own_selection_internal)
4757 (Fx_get_selection_internal, Fx_disown_selection_internal)
4758 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
4759 * nsselect.m (Fx_own_selection_internal)
4760 (Fx_disown_selection_internal, Fx_selection_exists_p)
4761 (Fx_selection_owner_p, Fx_get_selection_internal):
4762 Sync docs and argument specs with the xselect.c versions.
4764 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
4766 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
4768 2012-02-11 Eli Zaretskii <eliz@gnu.org>
4770 * w32select.c (Fx_selection_exists_p): Sync doc string and
4771 argument list with xselect.c. (Bug#10783)
4773 * w16select.c (Fx_selection_exists_p): Sync doc string and
4774 argument list with xselect.c. (Bug#10783)
4776 2012-02-10 Glenn Morris <rgm@gnu.org>

4780 2012-02-09 Kenichi Handa <handa@m17n.org>
4782 * coding.c (produce_chars): Fix updating of src_end (Bug#10701).
4784 2012-02-07 Chong Yidong <cyd@gnu.org>
4786 * buffer.c (Fbuffer_local_variables)
4787 (buffer_lisp_local_variables): Handle unbound vars correctly;
4788 don't let Qunbound leak into Lisp.
4790 2012-02-07 Glenn Morris <rgm@gnu.org>
4792 * image.c (Fimagemagick_types): Doc fix.
4794 * image.c (imagemagick-render-type): Change it from a lisp object
4795 to an integer. Move the doc here from the lisp manual.

4798 2012-02-06 Chong Yidong <cyd@gnu.org>
4800 * doc.c (store_function_docstring): Avoid applying docstring of
4801 alias to base function (Bug#2603).
4803 2012-02-04 Andreas Schwab <schwab@linux-m68k.org>
4805 * .gdbinit (pp1, pv1): Remove redundant defines.
4808 2012-02-04 Chong Yidong <cyd@gnu.org>
4810 * nsterm.m: Declare a global (Bug#10694).
4812 2012-02-04 Eli Zaretskii <eliz@gnu.org>
4814 * w32.c (get_emacs_configuration_options):
4815 Include --enable-checking, if specified, in the return value.

4824 * keyboard.c (adjust_point_for_property): Don't position point
4825 before BEGV. (Bug#10696)
4827 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
4829 Handle overflow when computing char display width (Bug#9496).
4830 * character.c (char_width): Return EMACS_INT, not int.
4831 (char_width, c_string_width): Check for overflow when
4832 computing the width; this is possible now that individual
4833 characters can have unbounded width. Problem introduced
4834 by merge from Emacs 23 on 2012-01-19.
4836 2012-02-02 Michael Albinus <michael.albinus@gmx.de>
4838 * dbusbind.c (Fdbus_register_method): Mention the return value

4851 2012-02-02 Kenichi Handa <handa@m17n.org>
4853 (x_produce_glyphs): Cancel previous change. If cmp->glyph_len is
4854 0, do not call append_composite_glyph.
4856 2012-02-02 Kenichi Handa <handa@m17n.org>
4858 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
4860 (x_produce_glyphs): If the component of a composition is a null
4861 string, set it->pixel_width to 1 to avoid zero-width glyph.
4863 2012-02-01 Eli Zaretskii <eliz@gnu.org>
4865 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
4866 first 2 arguments are identical. This makes inserting large
4867 output from a subprocess an order of magnitude faster on
4868 MS-Windows, where all sbrk'ed memory is always contiguous.
4870 2012-01-31 Glenn Morris <rgm@gnu.org>
4872 * nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:

4908 2012-01-21 Chong Yidong <cyd@gnu.org>
4910 * floatfns.c (Fcopysign): Make the second argument non-optional,
4911 since nil is not allowed anyway.
4913 2012-01-21 Andreas Schwab <schwab@linux-m68k.org>
4915 * process.c (read_process_output): Use p instead of XPROCESS (proc).
4916 (send_process): Likewise.

4924 2012-01-19 Kenichi Handa <handa@m17n.org>
4926 * character.c (char_width): New function.
4927 (Fchar_width, c_string_width, lisp_string_width):
4928 Use char_width (Bug#9496).
4930 2012-01-16 Martin Rudalics <rudalics@gmx.at>
4932 * window.c (Vwindow_persistent_parameters): New variable.
4933 (Fset_window_configuration, save_window_save): Handle persistent
4936 2012-01-14 Eli Zaretskii <eliz@gnu.org>
4938 * w32fns.c (signal_user_input): Don't do a QUIT, to avoid
4939 thrashing the stack of the thread. (Bug#9087)
4941 2012-01-12 Paul Eggert <eggert@cs.ucla.edu>
4943 * xdisp.c (rows_from_pos_range): Add parens as per gcc -Wparentheses.
4945 2012-01-11 Eli Zaretskii <eliz@gnu.org>

5483 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
5484 Otherwise, valgrind does not work on some platforms.
5485 Problem reported by Andreas Schwab in
5486 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
5487 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
5488 is set, removing the need for VIRT_ADDRESS_VARIES.
5489 (PURE_P): Use a more-efficient implementation that needs just one
5490 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
5491 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
5492 to 4 (xorl, subq, cmpq, setbe).
5493 * alloc.c (pure): Always extern now, since that's the
5494 VIRT_ADDR_VARIES behavior.
5495 (PURE_POINTER_P): Use a single comparison, not two, for
5496 consistency with the new puresize.h.
5497 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
5498 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

5505 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
5506 behave as if the cursor position were at the window margin.
5508 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
5509 and the cursor position is out of bounds, behave as if the cursor
5510 position were at the window margin. (Bug#10075)
5512 2011-11-18 Chong Yidong <cyd@gnu.org>
5514 * window.c (Fwindow_combination_limit): Make first argument

5537 (compute_line_metrics): Call row_hash, instead of computing the
5540 * dispnew.c (verify_row_hash): Call row_hash for computing the
5541 hash code of a row, instead of duplicating code from xdisp.c.

5579 * image.c (imagemagick_load_image): Fix typo.
5581 2011-11-14 Eli Zaretskii <eliz@gnu.org>
5583 * xdisp.c (display_line): Move the call to
5584 highlight_trailing_whitespace before the call to
5585 compute_line_metrics, since the latter needs to see the final
5586 faces of all the glyphs to compute ROW's hash value.
5587 Fixes assertion violations in row_equal_p. (Bug#10035)
5589 2011-11-14 Juanma Barranquero <lekktu@gmail.com>

5596 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
5597 with user-defined heap size. Bump the default size of the temacs
5598 heap to 27MB, to avoid memory warning when running temacs.
5599 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
5601 * dispnew.c (scrolling_window): Fix incorrect indices in accessing

5651 The trivial performance wins aren't worth the portability hassles; see
5652 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
5654 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

5656 (window_box_right, window_box_right_offset): Undo previous change,
5657 by removing the "extern"s.
5658 * intervals.c (adjust_intervals_for_insertion)
5659 (adjust_intervals_for_deletion): Undo previous change,
5660 making these static again.
5661 (offset_intervals, temp_set_point_both, temp_set_point)
5662 (copy_intervals_to_string): No longer inline.
5663 * xdisp.c (window_text_bottom_y, window_box_width)

5736 (static_offset_intervals): Remove.
5737 (offset_intervals): Rewrite using the old contents of
5738 static_offset_intervals. The old version didn't conform to C99
5739 because an extern inline function contained a reference to an

5912 so that this new function doesn't get optimized away by a
5913 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
5915 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
5917 * frame.h (MOUSE_HL_INFO): Remove excess parens.
5919 2011-10-29 Eli Zaretskii <eliz@gnu.org>
5921 Fix the `xbytecode' command.
5922 * .gdbinit (xprintbytestr): New command.
5923 (xwhichsymbols): Rename from `which'; all callers changed.
5924 (xbytecode): Print the byte-code string as well.
5926 2011-10-29 Kim Storm <storm@cua.dk>
5928 * alloc.c (which_symbols): New function.
5930 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
5932 * minibuf.c (read_minibuf_noninteractive): Allow reading empty
5935 2011-10-29 Glenn Morris <rgm@gnu.org>
5937 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
5938 Not clear what it was for, and it causes various bugs. (Bug#9839)
5940 2011-10-28 Eli Zaretskii <eliz@gnu.org>
5942 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
5943 possible random value that matches one of those tested as
5944 condition to clear the mouse face.
5946 2011-10-28 Chong Yidong <cyd@gnu.org>
5948 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.
5950 2011-10-28 Dan Nicolaescu <dann@ics.uci.edu>
5952 * window.c (make_window): Initialize phys_cursor_on_p.
5954 2011-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
5956 * lisp.h (struct Lisp_Symbol): Update comments.
5958 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
5960 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
5962 2011-10-28 Eli Zaretskii <eliz@gnu.org>
5964 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
5965 <oslsachem@gmail.com> for helping to debug this.
5967 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
5968 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
5969 (g_b_init_get_glyph_outline_w): New static variables.
5970 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
5971 (GetGlyphOutlineW_Proc): New typedefs.
5972 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
5973 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
5975 (w32font_open_internal, compute_metrics):
5976 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
5977 instead of calling the "wide" APIs directly.
5979 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
5981 * w32.h (syms_of_w32font): Add prototype.
5983 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
5985 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
5986 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
5987 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
5988 (Fmove_to_window_line): Doc fix.
5990 2011-10-27 Chong Yidong <cyd@gnu.org>
5992 * process.c (make_process): Set gnutls_state to NULL.
5994 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
5995 non-NULL, regardless of GNUTLS_INITSTAGE.
5996 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
5997 an error. Set process slots as soon as we allocate them.
5999 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
6001 2011-10-27 Chong Yidong <cyd@gnu.org>
6003 * gnutls.c (emacs_gnutls_deinit): New function.
6004 Deallocate credentials structures as well as calling gnutls_deinit.
6005 (Fgnutls_deinit, Fgnutls_boot): Use it.
6007 * process.c (make_process): Initialize GnuTLS credentials to NULL.
6008 (deactivate_process): Call emacs_gnutls_deinit.
6010 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
6012 * image.c (x_create_x_image_and_pixmap):
6013 * w32.c (sys_rename, w32_delayed_load):
6014 * w32font.c (fill_in_logfont):
6015 * w32reg.c (x_get_string_resource): Silence compiler warnings.
6017 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
6019 * w32fns.c (w32_default_color_map): New function,
6020 extracted from Fw32_default_color_map.
6021 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
6023 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
6025 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
6027 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
6029 * keyboard.c (test_undefined): New function (bug#9751).
6030 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
6032 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
6034 * sysdep.c (init_sys_modes): Fix the check for the controlling
6035 terminal (Bug#6649).
6037 2011-10-20 Eli Zaretskii <eliz@gnu.org>
6039 * dispextern.h (struct bidi_it): New member next_en_type.
6041 * bidi.c (bidi_line_init): Initialize the next_en_type member.
6042 (bidi_resolve_explicit_1): When next_en_pos is valid for the
6043 current character, check also for next_en_type being WEAK_EN.
6044 (bidi_resolve_weak): Don't enter the expensive loop if the current
6045 position is before next_en_pos. Record the bidi type of the first
6046 non-ET, non-BN character we find, in addition to its position.
6047 (bidi_level_of_next_char): Invalidate next_en_type when
6048 next_en_pos is over-stepped.
6050 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
6052 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
6053 * editfns.c: Rewrite current-time-zone so that it invokes
6054 the equivalent of (format-time-string "%Z") to get the time zone name.
6055 This fixes a bug when the time zone name contains characters that
6056 need converting from the system time locale to Emacs internal format.
6057 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
6058 that patch fixed format-time-string to do the conversion, but
6059 I forgot to fix current-time-zone.
6060 (format_time_string): New function, containing most of
6061 what Fformat_time_string used to contain.
6062 (Fformat_time_string): Rewrite in terms of format_time_string.
6063 This doesn't change this function's behavior.
6064 (current-time-zone): Rewrite to use format_time_string.
6065 This fixes the bug reported by Michael Schierl in
6066 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
6067 Jason Rumney's 2007-06-07 change worked around this bug, but
6069 * systime.h (tzname, timezone): Remove no-longer-used declarations.
6071 2011-10-19 Eli Zaretskii <eliz@gnu.org>
6073 * xdisp.c (start_display): If the character at POS is displayed
6074 via a display vector, reset IT->current.dpvec_index to zero.
6075 (try_window_reusing_current_matrix): If a line ends in a display
6076 vector or the next line starts in a display vector, continue
6077 redrawing the window even though the character position of
6078 start_row was reached.
6081 2011-10-18 Chong Yidong <cyd@gnu.org>
6083 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
6084 with nobreak-char-display too.
6086 2011-10-18 Eli Zaretskii <eliz@gnu.org>
6088 Fix part 3 of bug#9771.
6089 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
6090 (bidi_resolve_neutral): Don't enter the expensive loop looking for
6091 non-neutral characters if the current character is a paragraph
6092 separator (a.k.a. Newline). This avoids running the same
6093 expensive loop twice, once when we consume the preceding newline
6094 and the other time when the line actually needs to be displayed.
6095 Avoid the loop when we see neutrals on the base embedding level
6096 following a character whose directionality is the same as the
6097 paragraph's. This avoids running the expensive loop when a line
6098 ends in a long sequence of neutrals, like control characters.
6099 Add assertion against STRONG_AL type. Slightly rearrange code
6100 that determines the type of a neutral given the first non-neutral
6102 (bidi_level_of_next_char): Set next_en_pos to zero when
6103 invalidating its info.
6105 2011-10-17 Eli Zaretskii <eliz@gnu.org>
6107 * xdisp.c (push_display_prop): Determine whether to record string
6108 or buffer position by IT->string, not by IT->method. Allow
6109 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
6110 (move_it_vertically_backward): Don't look for character position
6111 immediately after the newline when in a continuation line.
6114 2011-10-15 Martin Rudalics <rudalics@gmx.at>
6116 * window.c (coordinates_in_window): Rewrite and delabelize
6117 vertical border check. (Bug#5357) (Bug#9618)
6119 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
6121 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
6122 errors in XSetWindowBorder (bug#9310).
6124 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
6126 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
6127 avoid crash when xmalloc overrun checking is enabled.
6129 2011-10-13 Eli Zaretskii <eliz@gnu.org>
6131 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
6132 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
6133 cursor motion with <left> and <right> arrow keys.
6135 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
6136 some callers set that themselves.
6138 2011-10-12 Eli Zaretskii <eliz@gnu.org>
6140 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
6141 display string and the previous row comes from the same string and
6142 is empty. (Bug#9739) (Bug#9738)
6144 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
6146 * doc.c (get_doc_string): Encode file name (bug#9735).
6148 2011-10-12 Eli Zaretskii <eliz@gnu.org>
6150 * bidi.c (bidi_level_of_next_char):
6151 * xdisp.c (get_visually_first_element): Remove old incorrect
6152 comments regarding the Unicode Line Separator character.
6154 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
6156 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
6158 * alloc.c (Fgc_status): Do not access beyond zombies array
6159 boundary if nzombies > MAX_ZOMBIES.
6160 * alloc.c (dump_zombies): Add missing format specifier.
6162 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
6164 * xdisp.c (set_cursor_from_row): Simplify conditionals,
6165 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
6167 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
6168 Some packages use them to denote characters with modifiers.
6170 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
6172 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
6173 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
6174 matching a pp-number. Rename parameter var to var1.
6176 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
6178 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
6180 2011-10-08 Glenn Morris <rgm@gnu.org>
6182 * callint.c (Fcall_interactively): Give a more explicit error for the
6183 'c' case with a non-character input. (Bug#8479)
6185 2011-10-08 Eli Zaretskii <eliz@gnu.org>
6187 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
6189 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
6190 lines that are hscrolled on the left.
6192 * dispnew.c (buffer_posn_from_coords): Account for a possible
6193 presence of header-line. (Bug#4426)
6195 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
6197 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
6198 Don't advertise functionality which we discourage or doesn't work.
6200 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
6202 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
6203 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
6204 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
6205 this makes Emacs dump core during garbage collection on rare
6206 occasions. sizeof is obviously inferior to offsetof here, so
6207 stick with offsetof.
6208 (GC_POINTER_ALIGNMENT): New macro.
6209 (mark_memory): Omit 3rd (offset) arg; caller changed.
6210 Don't assume EMACS_INT alignment is the same as pointer alignment.
6212 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
6214 * keyboard.c (read_key_sequence_remapped): New var.
6215 (read_key_sequence): Compute remapping in the right buffer.
6216 (command_loop_1): Use read_key_sequence's remapping directly.
6218 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
6220 * dired.c (file_name_completion): Don't expand file name.
6221 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
6222 before checking file name handler.
6224 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
6225 they've been requested explicitly (bug#9591).
6227 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
6229 * keymap.c (Fsingle_key_description): Use make_specified_string
6230 instead of build_string to build string from push_key_description.
6233 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
6235 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
6236 This fixes a Y2038 bug on 64-bit hosts.
6237 * buffer.c (reset_buffer):
6238 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
6239 (Fclear_buffer_auto_save_failure):
6240 Use 0, not -1, to represent an unset failure time, since time_t
6241 might not be signed.
6243 Remove dependency on glibc malloc internals.
6244 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6245 Move back here from lisp.h, but with their new implementations.
6246 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
6247 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
6248 * charset.c (charset_table_init): New static var.
6249 (syms_of_charset): Use it instead of xmalloc. This removes a
6250 dependency on glibc malloc internals. See Eli Zaretskii's comment in
6251 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
6252 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6253 Move back to alloc.c.
6254 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
6255 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
6257 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
6259 * nsterm.m (windowDidResize): Call x_set_window_size only when
6260 ns_in_resize is true. Otherwise set pixelwidth/height and
6261 call change_frame_size (Bug#9628).
6263 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
6265 Port --enable-checking=all to Fedora 14 x86-64.
6266 * charset.c (syms_of_charset): Also account for glibc malloc's
6267 internal overhead when calculating the initial malloc maximum.
6269 Port --enable-checking=all to Fedora 14 x86.
6270 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6272 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
6273 (overrun_check_realloc, overrun_check_free):
6274 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
6275 That way, xmalloc returns a properly-aligned pointer even if
6276 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
6277 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
6278 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
6279 into account when calculating the initial malloc maximum.
6280 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6281 Move here from alloc.c, so that charset.c can use it too.
6282 Properly align; the old code wasn't right for common 32-bit hosts
6283 when configured with --enable-checking=all.
6284 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
6285 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
6287 2011-09-29 Eli Zaretskii <eliz@gnu.org>
6289 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
6292 2011-09-28 Eli Zaretskii <eliz@gnu.org>
6294 * xdisp.c (compute_display_string_end): If there's no display
6295 string at CHARPOS, return -1.
6297 * bidi.c (bidi_fetch_char): When compute_display_string_end
6298 returns a negative value, treat the character as a normal
6299 character not covered by a display string. (Bug#9624)
6301 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
6303 * lread.c (Fread_from_string): Fix typo in docstring.
6305 2011-09-27 Eli Zaretskii <eliz@gnu.org>
6307 * xdisp.c (handle_invisible_prop): If invisible text ends on a
6308 newline, reseat the iterator instead of bidi-iterating there one
6309 character at a time. (Bug#9610)
6310 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
6311 TO_CHARPOS if the bidi iterator is at base embedding level.
6313 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
6315 * lread.c (readevalloop): Use correct code for NBSP.
6316 (read1): Likewise. (Bug#9608)
6318 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
6320 * dbusbind.c (Fdbus_register_signal): When service is not
6321 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
6323 2011-09-25 Glenn Morris <rgm@gnu.org>
6325 * buffer.c (truncate-lines): Doc fix.
6327 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
6329 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
6330 (Fset_window_next_buffers): Doc fix.
6332 2011-09-24 Glenn Morris <rgm@gnu.org>
6334 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
6336 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
6338 Fix minor problems found by static checking.
6339 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
6340 * indent.c (Fvertical_motion): Fix == vs = typo.
6342 2011-09-24 Eli Zaretskii <eliz@gnu.org>
6344 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
6345 Default value is now t. Doc fix.
6347 * indent.c (Fvertical_motion): Compute and apply the overshoot
6348 logic when moving up, not only when moving down. Fix the
6349 confusing name and values of the it_overshoot_expected variable;
6350 logic changes accordingly. (Bug#9254) (Bug#9549)
6352 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
6353 CHARPOS is covered by a display string which includes newlines.
6354 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
6355 is covered by a display string with embedded newlines.
6357 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
6359 * dbusbind.c (Fdbus_register_signal): Add match rule to
6360 Vdbus_registered_objects_table. (Bug#9581)
6361 (Fdbus_register_method, Vdbus_registered_objects_table):
6364 2011-09-24 Jim Meyering <meyering@redhat.com>
6366 do not ignore write error for any output size
6367 The previous change was incomplete.
6368 While it makes emacs --batch detect the vast majority of stdout
6369 write failures, errors were still ignored whenever the output size is
6370 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
6371 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
6372 && echo FAIL: ignored write error
6373 FAIL: ignored write error
6374 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
6375 && echo FAIL: ignored write error

6397 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
6398 Handle the case of a display string with multiple newlines.
6399 (Fcurrent_bidi_paragraph_direction): Fix search for previous
6400 non-empty line. Fixes confusing cursor motion with arrow keys at
6401 the beginning of a line that starts with whitespace.

6413 2011-09-18 Eli Zaretskii <eliz@gnu.org>
6415 * xdisp.c (display_line): Record maximum and minimum buffer
6416 positions even if no glyphs were produced (e.g., by a zero-width
6417 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
6418 buffer positions that will be removed from the glyph row because
6420 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
6421 column is beyond frame width: don't subtract 1 "pixel" when
6422 computing width of the stretch.
6423 (reseat_at_next_visible_line_start): Undo the change made on
6424 2011-09-17 that saved paragraph information and restored it after
6425 the call to `reseat'. (Bug#9545)
6427 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6429 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
6430 and turn window cursor on if cleared (Bug#9415).
6432 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
6434 * search.c (boyer_moore): Take unibyte characters from pattern
6435 literally. (Bug#9458)
6437 2011-09-18 Eli Zaretskii <eliz@gnu.org>
6439 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.

6443 Fix minor problem found by static checking.
6444 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
6445 initialized, to pacify gcc -Wuninitialized.
6447 * fileio.c: Report proper errno when syscall falls.
6448 (Finsert_file_contents): Save and restore errno,
6449 so that report_file_error outputs the correct diagnostic.
6450 (Fwrite_region) [CLASH_DETECTION]: Likewise.
6452 2011-09-18 Eli Zaretskii <eliz@gnu.org>
6454 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
6456 2011-09-17 Eli Zaretskii <eliz@gnu.org>
6458 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
6459 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
6461 2011-09-17 Eli Zaretskii <eliz@gnu.org>
6463 * xdisp.c (reseat_at_next_visible_line_start): Keep information
6464 about the current paragraph and restore it after the call to reseat.
6466 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
6467 (bidi_find_paragraph_start): Search back for paragraph beginning
6468 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
6469 (bidi_move_to_visually_next): Only trigger paragraph-related
6470 computations when the last character is a newline or at EOB, not
6471 just any NEUTRAL_B. (Bug#9470)
6473 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
6474 truncated lines if point is covered by a display string. (Bug#9524)
6476 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
6478 * xselect.c: Relax test for outgoing X longs (Bug#9498).
6479 (cons_to_x_long): New function.
6480 (lisp_data_to_selection_data): Use it. Correct the test for
6481 short-versus-long data; it was negated. Break out of vector
6482 loop, for efficiency, when a long datum is discovered.
6484 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
6486 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
6488 2011-09-16 Eli Zaretskii <eliz@gnu.org>
6490 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
6491 GCC PR/17406) by declaring this function with external scope.
6493 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>

6510 of TAB characters in a composition.
6512 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
6514 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
6515 This occurs when processing a multibyte format.
6516 Problem reported by Wolfgang Jenker.
6518 2011-09-15 Johan Bockgård <bojohan@gnu.org>
6520 * xdisp.c (try_cursor_movement): Only check for exact match if
6521 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
6523 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
6525 Remove unused external symbols.
6526 * dispextern.h (calc_pixel_width_or_height): Remove decl.

6533 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
6535 * xselect.c: Use signed conversions more consistently (Bug#9498).
6536 (selection_data_to_lisp_data): Assume incoming selection data are
6537 signed integers, not unsigned. This is to be consistent with
6538 outgoing selection data, which was modified to use signed integers
6539 in as part of the fix to Bug#9196 in response to Jan D.'s comment
6540 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
6541 expects long, not unsigned long.
6543 2011-09-14 Eli Zaretskii <eliz@gnu.org>
6545 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
6546 computation of loop end. Reported by Johan Bockgård
6549 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
6551 * frame.c (Fother_visible_frames_p): Function deleted.
6553 2011-09-12 Eli Zaretskii <eliz@gnu.org>
6555 * indent.c (compute_motion): Process display vector front to back
6556 rather than the other way around. (Bug#2496)
6558 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
6560 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
6562 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
6564 * minibuf.c (Fread_from_minibuffer): Doc fix.
6566 2011-09-11 Eli Zaretskii <eliz@gnu.org>
6568 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
6569 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
6571 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
6573 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
6574 value for non-existent files.
6576 2011-09-11 Eli Zaretskii <eliz@gnu.org>
6578 * fileio.c (Finsert_file_contents): If the file cannot be opened,
6579 set its "size" to -1. This will set the modtime_size field of
6580 the corresponding buffer to -1, which is what
6581 verify-visited-file-modtime expects for files that do not exist.
6584 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
6586 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
6588 * lisp.h: ... from here. push_key_description is no longer
6589 defined in keyboard.c, so its declaration should not be in
6590 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
6591 logically belongs with push_key_description.
6593 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
6595 * buffer.h: Include <sys/types.h> instead of <time.h>.
6596 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
6597 Problem reported by Herbert J. Skuhra.
6599 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
6601 * xml.c (parse_region): Make the parsing work for
6602 non-comment-starting XML files again (bug#9144).
6604 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
6606 * image.c (gif_load): Fix calculation of bottom and right corner.
6609 2011-09-10 Eli Zaretskii <eliz@gnu.org>
6611 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
6612 redisplay in small windows.
6614 2011-09-09 Eli Zaretskii <eliz@gnu.org>
6616 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
6618 2011-09-08 Martin Rudalics <rudalics@gmx.at>
6620 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
6621 Operate on live windows only.
6623 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
6625 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
6627 2011-09-07 Eli Zaretskii <eliz@gnu.org>
6629 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
6630 only under bidi iteration.
6632 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
6634 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
6636 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
6638 isnan: Fix porting problem to Solaris 10 with bundled gcc.
6639 Without this fix, the command to link temacs failed due to an
6640 undefined symbol __builtin_isnan. This is because
6641 /usr/include/iso/math_c99.h #defines isnan(x) to
6642 __builtin_isnan(x), but the bundled gcc, which identifies itself
6643 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
6645 * floatfns.c (isnan): #undef, and then #define to a clone of
6647 (Fisnan): Always define, since it's always available now.
6648 (syms_of_floatfns): Always define isnan at the Lisp level.
6650 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
6652 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
6654 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
6656 * fileio.c: Fix bugs with large file offsets (Bug#9428).
6657 The previous code assumed that file offsets (off_t values) fit in
6658 EMACS_INT variables, which is not true on typical 32-bit hosts.
6659 The code messed up by falsely reporting buffer overflow in cases
6660 such as (insert-file-contents "big" nil 1 2) into an empty buffer
6661 when "big" contains more than 2**29 bytes, even though this
6662 inserts just one byte and does not overflow the buffer.
6663 (Finsert_file_contents): Store file offsets as off_t
6664 values, not as EMACS_INT values. Check for overflow when
6665 converting between EMACS_INT and off_t. When checking for
6666 buffer overflow or for overlap, take the offsets into account.
6667 Don't use EMACS_INT for small values where int suffices.
6668 When checking for overlap, fix a typo: ZV was used where
6669 ZV_BYTE was intended.
6670 (Fwrite_region): Don't assume off_t fits into 'long'.
6671 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
6673 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
6675 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
6677 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
6679 sprintf-related integer and memory overflow issues (Bug#9412).
6681 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
6682 (esprintf, exprintf, evxprintf): New functions.
6683 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
6684 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
6685 (modify_event_symbol): Do not assume that the length of
6686 name_alist_or_stem is safe to alloca and fits in int.
6687 (Fexecute_extended_command): Likewise for function name and binding.
6688 (Frecursion_depth): Wrap around reliably on integer overflow.
6689 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
6690 since some callers pass EMACS_INT values.
6691 (Fsingle_key_description): Don't crash if symbol name contains more
6692 than MAX_ALLOCA bytes.
6693 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
6694 (get_minibuffer): Arg is now EMACS_INT, not int.
6695 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
6696 (esprintf, exprintf, evxprintf): New decls.
6697 * window.h (command_loop_level, minibuf_level): Reflect API changes.
6699 * dbusbind.c (signature_cat): New function.
6700 (xd_signature, Fdbus_register_signal):
6701 Do not overrun buffer; instead, report string overflow.
6703 * dispnew.c (add_window_display_history): Don't overrun buffer.
6704 Truncate instead; this is OK since it's just a log.
6706 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
6707 even if the time zone offset is outlandishly large.
6708 Don't mishandle offset == INT_MIN.
6710 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
6711 when creating daemon; the previous buffer-overflow check was incorrect.
6713 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
6714 which has the guts of the old verror function.
6716 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
6717 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
6719 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
6720 (font_unparse_xlfd): Don't blindly alloca long strings.
6721 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
6722 fits in int, when using sprintf. Use single snprintf to count
6723 length of string rather than counting it via multiple sprintfs;
6724 that's simpler and more reliable.
6725 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
6726 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
6727 sprintf, in case result does not fit in int.
6729 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
6730 (fontset_from_font): Print it.
6732 * frame.c (tty_frame_count): Now printmax_t, not int.
6733 (make_terminal_frame, set_term_frame_name): Print it.
6734 (x_report_frame_params): In X, window IDs are unsigned long,
6735 not signed long, so print them as unsigned.
6736 (validate_x_resource_name): Check for implausibly long names,
6737 and don't assume name length fits in 'int'.
6738 (x_get_resource_string): Don't blindly alloca invocation name;
6739 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
6742 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
6743 (xg_check_special_colors, xg_set_geometry):
6744 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
6746 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
6747 Use esprintf, not sprintf, in case result does not fit in int.
6749 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
6750 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
6751 it as a large positive number.
6752 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
6753 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
6755 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
6756 in case result does not fit in int.
6758 * print.c (float_to_string): Detect width overflow more reliably.
6759 (print_object): Make sprintf buffer a bit bigger, to avoid potential
6760 buffer overrun. Don't assume list length fits in 'int'. Treat
6761 print length of 0 as 0, not as infinity; to be consistent with other
6762 uses of print length in this function. Don't overflow print length
6763 index. Don't assume hash table size fits in 'long', or that
6764 vectorlike size fits in 'unsigned long'.
6766 * process.c (make_process): Use printmax_t, not int, to format
6767 process-name gensyms.
6769 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
6771 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
6772 to avoid potential buffer overrun.
6774 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
6775 if X resource line is longer than 512 bytes.
6777 * xfns.c (x_window): Make sprintf buffer a bit bigger
6778 to avoid potential buffer overrun.
6780 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
6782 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
6784 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
6786 Integer overflow fixes for scrolling, etc.
6787 Without these, Emacs silently mishandles large integers sometimes.
6788 For example, "C-u 4294967297 M-x recenter" was treated as if
6789 it were "C-u 1 M-x recenter" on a typical 64-bit host.
6791 * xdisp.c (try_window_id): Check Emacs fixnum range before
6792 converting to 'int'.
6794 * window.c (window_scroll_line_based, Frecenter):
6795 Check that an Emacs fixnum is in range before assigning it to 'int'.
6796 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
6797 values converted from Emacs fixnums.
6798 (Frecenter): Don't wrap around a line count if it is out of 'int'
6799 range; instead, treat it as an extreme value.
6800 (Fset_window_configuration, compare_window_configurations):
6801 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
6803 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
6804 that can exceed INT_MAX. Check that EMACS_INT value is in range
6805 before assigning it to the (possibly-narrower) index.
6806 (match_limit): Don't assume that a fixnum can fit in 'int'.
6808 * print.c (print_object): Use ptrdiff_t, not int, for index that can
6811 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
6812 (Fvertical_motion): Don't wrap around LINES values that don't fit
6813 in 'int'. Instead, treat them as extreme values. This is good
6814 enough for windows, which can't have more than INT_MAX lines anyway.
6816 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
6818 * Require libxml/parser.h to avoid compilation warning.
6820 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
6822 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
6823 since this reportedly can destroy thread storage.
6825 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
6827 * syntax.c (find_defun_start): Update all cache variables if
6828 exiting early (Bug#9401).
6830 2011-08-30 Eli Zaretskii <eliz@gnu.org>
6832 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
6834 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
6835 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
6836 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
6838 * term.c (tty_append_glyph): New function.
6839 (produce_stretch_glyph): Static function and its prototype deleted.
6841 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
6844 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
6846 * image.c (parse_image_spec): Check for nonnegative, not for positive,
6847 when checking :margin (Bug#9390).
6848 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
6849 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
6850 so that the name doesn't mislead. All uses changed.
6852 2011-08-28 Johan Bockgård <bojohan@gnu.org>
6854 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
6857 2011-08-27 Eli Zaretskii <eliz@gnu.org>
6859 * xdisp.c (move_it_to): Don't bail out early when reaching
6860 position beyond to_charpos, if we are scanning backwards.
6861 (move_it_vertically_backward): When DY == 0, make sure we get to
6862 the first character in the line after the newline.
6864 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
6866 * ccl.c: Improve and simplify overflow checking (Bug#9196).
6867 (ccl_driver): Do not generate an out-of-range pointer.
6868 (Fccl_execute_on_string): Remove unnecessary check for
6869 integer overflow, noted by Stefan Monnier in
6870 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
6871 Remove a FIXME that didn't need fixing.
6872 Simplify the newly-introduced buffer reallocation code.
6874 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
6876 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
6878 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
6880 Integer and memory overflow issues (Bug#9196).
6882 * doc.c (get_doc_string): Rework so that
6883 get_doc_string_buffer_size is the actual buffer size, rather than
6884 being 1 less than the actual buffer size; this makes xpalloc more
6887 * image.c (x_allocate_bitmap_record, cache_image):
6888 * xselect.c (Fx_register_dnd_atom):
6889 Simplify previous changes by using xpalloc.
6891 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
6892 since either will do and ptrdiff_t is convenient with xpalloc.
6894 * charset.c (charset_table_size)
6895 (struct charset_sort_data.priority): Now ptrdiff_t.
6896 (charset_compare): Don't overflow if priorities differ greatly.
6897 (Fsort_charsets): Don't assume list length fits in int.
6898 Check for size-calculation overflow when allocating sort data.
6899 (syms_of_charset): Allocate an initial charset table that is
6900 just under 64 KiB, to avoid problems with glibc malloc and mmap.
6902 * cmds.c (internal_self_insert): Check for size-calculation overflow.
6904 * composite.h (struct composition.glyph_len): Now int, not unsigned.
6905 The actual value is always <= INT_MAX, and leaving it unsigned made
6906 overflow checking harder.
6908 * dispextern.h (struct glyph_matrix.rows_allocated)
6909 (struct face_cache.size): Now ptrdiff_t, for convenience in use
6910 with xpalloc. The values are still always <= INT_MAX.
6912 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
6914 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
6915 (SAFE_NALLOCA): New macro.
6917 * region-cache.c (struct boundary.pos, find_cache_boundary)
6918 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
6919 (set_cache_region, invalidate_region_cache)
6920 (revalidate_region_cache, know_region_cache, region_cache_forward)
6921 (region_cache_backward, pp_cache):
6922 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
6923 so that ptrdiff_t * can be passed to xpalloc.
6924 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
6925 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
6926 (pp_cache): Don't assume cache_len fits in int.
6927 * region-cache.h: Adjust extern decls to match.

6930 EMACS_INT, since either will do, for xpalloc.
6932 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
6933 (xnmalloc, xnrealloc, xpalloc): New functions.
6935 * bidi.c (bidi_shelve_header_size): New constant.

6937 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
6939 * bidi.c (bidi_cache_shrink):
6940 * buffer.c (overlays_at, overlays_in, record_overlay_string)
6942 Don't update size of array until after memory allocation succeeds,
6943 because xmalloc/xrealloc may not return.
6944 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
6945 now that we have proper integer overflow checking.
6946 (record_overlay_string, overlay_strings): Catch overflows when
6947 calculating size of overlay_str_buf.
6949 * callproc.c (Fcall_process): Check for size overflow when
6950 calculating size of args2.
6951 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
6952 Normally we prefer signed values, but sticking with ptrdiff_t would
6953 require adding more-complicated checks.
6955 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
6956 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
6957 Redo buffer-overflow calculations to avoid integer overflow.
6958 Add a FIXME comment where memory seems to be over-allocated.
6960 * character.c (Fstring): Check for size-calculation overflow.
6962 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
6963 unnecessary integer overflow. Check for size overflow.
6964 (encode_coding_object): Don't update size until xmalloc succeeds.
6966 * composite.c (get_composition_id): Check for overflow in glyph
6967 length calculations.
6969 Integer and memory overflow fixes for display code.
6970 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
6971 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
6972 (scrolling_window): Check for overflow in size calculations.
6973 (line_draw_cost, realloc_glyph_pool, add_row_entry):

6985 (get_doc_string): Check for size calculation overflow.
6986 Don't update size until allocation succeeds.
6987 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
6988 EMACS_INT, where ptrdiff_t will do.
6989 (Fsubstitute_command_keys): Check for string overflow.
6991 * editfns.c (set_time_zone_rule): Don't assume environment length
6993 (message_length): Now ptrdiff_t, not int.
6994 (Fmessage_box): Don't update size until allocation succeeds.
6995 Don't assume message length fits in int.
6996 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
6998 * emacs.c (main): Do not reallocate argv, since there is a null at
6999 the end that can be overwritten, and this way there's no need to
7000 worry about size-calculation overflow.
7001 (sort_args): Check for size-calculation overflow.
7003 * eval.c (init_eval_once, grow_specpdl): Don't update size until
7005 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
7007 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
7008 (x_set_scroll_bar_width, x_figure_window_size):
7009 Check for integer overflow.
7010 (x_set_alpha): Do not assume XINT fits in int.
7012 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
7013 This is for the members text_lines, text_cols, total_lines, total_cols,
7014 where the system imposes an 'int' limit.
7016 * fringe.c (Fdefine_fringe_bitmap):
7017 Don't update size until alloc works.
7019 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
7020 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
7022 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
7023 Check for size-calculation overflow.
7024 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
7025 do, as we prefer signed integers.
7026 (id_to_widget.max_size, id_to_widget.used)
7027 (xg_store_widget_in_map, xg_remove_widget_from_map)
7028 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
7029 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
7030 Use and return ptrdiff_t, not int.
7031 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
7032 * gtkutil.h: Change prototypes to match the above.
7034 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
7035 are duplicate now that they've been promoted to lisp.h.
7036 (x_allocate_bitmap_record, x_alloc_image_color)
7037 (make_image_cache, cache_image, xpm_load):
7038 Don't update size until alloc is done.

7048 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
7049 Use ptrdiff_t, not int, to count maps.
7050 (read_char_minibuf_menu_prompt): Check for overflow in size

7079 (Fset_match_data): Don't assume list lengths fit in 'int'.
7081 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
7082 for command line length. Do not attempt to address one before the

7086 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
7088 (encode_terminal_code, calculate_costs): Check for size
7089 calculation overflow.

7091 table lengths and related sizes. Don't update size until alloc
7092 done. Redo calculations to avoid overflow.
7093 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
7095 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of

7111 Use ptrdiff_t, not int, for sizes.
7112 (Finternal_make_lisp_face, cache_face):
7113 Check for size calculation overflow.
7114 (cache_face): Treat size calculation overflows as if they were
7115 memory exhaustion (the usual treatment), rather than aborting.
7117 * xfns.c (x_encode_text, x_set_name_internal)
7118 (Fx_change_window_property): Use ptrdiff_t, not int, to count
7119 sizes, since they can exceed INT_MAX in size. Check for size

7123 (xg_select): Check for size calculation overflow.
7124 Don't update size until alloc done.
7126 * xrdb.c (get_environ_db): Don't assume path length fits in int,

7129 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
7130 (X_LONG_MIN): New macros.
7131 Use them to make the following changes clearer.
7132 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
7133 This change doesn't affect the value now, but it may help remind
7134 future maintainers not to raise the value too much later.
7135 (SELECTION_QUANTUM): Remove, replacing with ...
7136 (selection_quantum): ... new function, which avoids overflow.
7138 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
7139 assumption that selection length fits in 'int'.

7147 Redo calculations to avoid overflow.
7148 (x_reply_selection_request): When sending hint, ceiling it at
7149 X_LONG_MAX rather than relying on wraparound overflow to send

7152 (lisp_data_to_selection_data, x_property_data_to_lisp):
7153 Check for size-calculation overflow.

7156 Don't store size until memory allocation succeeds.
7157 (x_get_window_property): Plug memory leak on memory exhaustion.
7158 Don't double-block input; malloc is safe here. Don't assume 2**34
7159 - 4 fits in unsigned long. Add an xassert to check
7160 XGetWindowProperty overflow. Be more careful about overflow
7161 calculations, and distinguish size from memory overflow better.
7162 (receive_incremental_selection): When tracing, don't assume
7163 unsigned int is less than INT_MAX.
7164 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
7165 harmful) conversions of unsigned short to int.
7166 (lisp_data_to_selection_data): Don't assume that integers
7167 in the range -65535 through -1 fit in an X unsigned short.
7168 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
7169 result parameters unless successful. Rely on cons_to_unsigned
7170 to report problems with elements; the old code wasn't right anyway.
7171 (x_check_property_data): Check for int overflow; we cannot use
7172 a wider type due to X limits.
7173 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

7204 * image.c (xpm_get_color_table_h):
7205 * lisp.h (hash_lookup, hash_put):
7206 * minibuf.c (Ftest_completion):
7207 Use ptrdiff_t for hash table indexes, not int (which is too
7208 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
7209 32-bit --with-wide-int hosts).
7211 * charset.c (Fdefine_charset_internal): Check for integer overflow.
7212 Add a FIXME comment about memory leaks.

7217 * character.h (CHAR_WIDTH):
7218 * indent.c (MULTIBYTE_BYTES_WIDTH):
7219 Use sanitize_char_width to avoid undefined and/or bad behavior
7220 with outlandish widths.
7221 * character.h (sanitize_tab_width): Rename from sanitize_width,
7222 now that we have two such functions. All uses changed.
7223 (sanitize_char_width): New inline function.
7225 Don't assume that tab-width fits in int.
7226 * character.h (sanitize_width): New inline function.
7227 (SANE_TAB_WIDTH): New macro.

7244 ptrdiff_t and size_t limits.
7246 * keyboard.c: Overflow, signedness and related fixes.
7247 (make_lispy_movement): Use same integer type in forward decl
7248 that is used in the definition.
7249 (read_key_sequence, keyremap_step):
7250 Change bufsize argument back to int, undoing my 2011-03-30 change.
7251 We prefer signed types, and int is wide enough here.
7252 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
7253 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
7254 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
7255 length, not size_t. Use ptrdiff_t for index, not int.
7256 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
7257 possibility of integer overflow.
7259 Overflow, signedness and related fixes for images.

7269 * xdisp.c (calc_pixel_width_or_height):
7270 * xfns.c (image_cache_refcount):

7272 on typical 64-bit hosts.
7274 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
7275 (x_bitmap_pixmap, x_create_x_image_and_pixmap):

7280 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
7281 (lookup_image): Remove unnecessary tests.

7284 (png_load, gif_load, svg_load_image):
7285 Prefer int to unsigned where either will do.
7286 (tiff_handler): New function, combining the cores of the
7287 old tiff_error_handler and tiff_warning_handler.
7288 This function is rewritten to use vsnprintf and thereby avoid
7289 stack buffer overflows. It uses only the features of vsnprintf
7290 that are common to both POSIX and native Microsoft.
7291 (tiff_error_handler, tiff_warning_handler): Use it.
7292 (tiff_load, gif_load, imagemagick_load_image):
7293 Don't assume :index value fits in 'int'.
7294 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.

7296 the integer types that MagickCropImage accepts. Don't assume
7297 Vimagemagick_render_type has a nonnegative value. Don't assume
7298 size_t fits in 'long'.

7312 handle_single_display_spec, not just 1 or zero.
7313 (handle_single_display_spec): If the display spec is of the form
7314 `(space ...)', and specifies display in the text area, return 2
7316 (try_cursor_movement): Check for the need to scroll more
7317 accurately, and prefer exact match for point under bidi.

7367 extra slot even if the purpose is char-code-property-table.
7369 2011-08-23 Eli Zaretskii <eliz@gnu.org>
7371 * xdisp.c (redisplay_window): When computing centering_position,
7372 account for the height of the header line. (Bug#8874)
7374 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
7375 instead of CHAR_TO_BYTE. Fixes a crash when a completion
7376 candidate is selected by the mouse, and that candidate has a
7377 composed character under the mouse.
7379 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
7380 coordinates reported by pos-visible-in-window-p for a composed
7381 character in column zero.

7387 2011-08-22 Eli Zaretskii <eliz@gnu.org>
7389 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
7390 consider it a hit if to_charpos is anywhere in the range of the
7391 composed buffer positions.
7393 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
7395 * image.c (gif_load): Don't assume that each subimage has the same
7396 dimensions as the base image. Handle disposal method that is
7397 "undefined" by the gif spec (Bug#9335).
7399 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
7401 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
7402 (Fcondition_case): Document `debug' symbol in error handler.
7404 2011-08-19 Eli Zaretskii <eliz@gnu.org>
7406 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
7407 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
7408 from an Org mode buffer to a Speedbar frame.
7410 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
7411 a composition, take its buffer position from IT->cmp_it.charpos.
7412 Fixes cursor positioning at the beginning of a line that begins
7413 with a composed character.
7415 2011-08-18 Eli Zaretskii <eliz@gnu.org>
7417 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
7418 character bidirectional type, use STRONG_L instead. Fixes crashes
7419 in a buffer produced by `describe-categories'.
7421 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
7422 members before the level stack, so they would be saved and
7423 restored when copying iterator state. Fixes incorrect reordering
7424 around TABs covered by display properties.
7426 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
7428 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

7433 (internal_condition_case_2, internal_condition_case_n):
7434 Remove unnecessary aborts (Bug#9081).
7436 2011-08-17 Eli Zaretskii <eliz@gnu.org>
7438 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
7439 has no `load' handler, try opening the file locally. (Bug#9311)
7441 2011-08-16 Ken Brown <kbrown@cornell.edu>

7510 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
7511 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
7512 the event loop. Get status from as_status (Bug#7276).
7514 * nsterm.m (sendEvent): If event is NSApplicationDefined and
7515 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
7516 the event loop (Bug#7276).

7542 (Fnetwork_interface_list): Allocate in increments of bytes instead
7543 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
7544 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
7546 (struct ifflag_def): notrailers is smart on OSX.
7547 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
7548 Get hardware address with getifaddrs if available.
7550 2011-08-12 Eli Zaretskii <eliz@gnu.org>
7552 * xdisp.c (iterate_out_of_display_property): xassert that
7553 IT->position is set to within IT->object's boundaries. Break from

7556 Set IT->current to match the bidi iterator unconditionally.
7557 (push_display_prop): Allow GET_FROM_STRING as IT->method on
7558 entry. Force push_it to save on the stack the current
7559 buffer/string position, to be restored by pop_it. Fix flags in
7560 the iterator structure wrt the object coming from a display
7561 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
7562 properties. (Bug#9284)
7564 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
7566 * fontset.c (fontset_get_font_group): Add proper type checks.

7591 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
7593 * composite.c (autocmp_chars): Don't reset point. That is done by
7594 restore_point_unwind (Bug#5984).
7596 2011-08-07 Juri Linkov <juri@jurta.org>
7598 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
7599 to show the arg `TIME' instead of `TIMEVAL'.
7601 2011-08-06 Eli Zaretskii <eliz@gnu.org>
7603 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a

7607 word-wrap under bidirectional display. (Bug#9224)
7609 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
7610 is non-zero, even if the data buffer is NULL. Fixes a crash in
7611 vertical-motion with longlines-mode. (Bug#9254)
7613 2011-08-05 Eli Zaretskii <eliz@gnu.org>
7615 * bidi.c <bidi_cache_total_alloc>: Now static.

7621 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
7622 amount allocated this far in `bidi_cache_total_alloc'.
7623 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
7624 non-zero, only free the data buffer without restoring the cache
7625 contents. All callers changed.
7627 * dispextern.h (bidi_unshelve_cache): Update prototype.
7629 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
7630 (move_it_in_display_line, move_it_to)
7631 (move_it_vertically_backward, move_it_by_lines): Replace the call
7632 to xfree to an equivalent call to bidi_unshelve_cache.

7689 * bidi.c (bidi_fetch_char): Accept an additional argument
7690 DISP_PROP_P, and pass it to compute_display_string_pos.
7691 Only handle text covered by a display string if DISP_PROP_P is returned

7779 Without this fix, if a signal arrives just after memory fills up,
7780 'malloc' might be invoked reentrantly.
7782 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
7783 In other words, assume that every image size is allowed, on non-X
7784 hosts. This assumption is probably wrong, but it lets Emacs compile.

7802 Integer signedness and overflow and related fixes. (Bug#9079)
7804 * bidi.c: Integer size and overflow fixes.
7805 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
7806 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
7807 (bidi_cache_find_level_change, bidi_cache_ensure_space)
7808 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
7809 (bidi_find_other_level_edge):
7810 Use ptrdiff_t instead of EMACS_INT where either will do.
7811 This works better on 32-bit hosts configured --with-wide-int.
7812 (bidi_cache_ensure_space): Check for size-calculation overflow.
7813 Use % rather than repeated addition, for better worst-case speed.
7814 Don't set bidi_cache_size until after xrealloc returns, because it
7816 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
7817 (bidi_cache_ensure_space): Also check that the bidi cache size
7818 does not exceed that of the largest Lisp string or buffer. See Eli
7819 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
7821 * alloc.c (__malloc_size_t): Remove.
7822 All uses replaced by size_t. See Andreas Schwab's note
7823 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
7825 * image.c: Improve checking for integer overflow.
7826 (check_image_size): Assume that f is nonnull, since
7827 it is always nonnull in practice. This is one less thing to
7828 worry about when checking for integer overflow later.
7829 (x_check_image_size): New function, which checks for integer
7830 overflow issues inside X.
7831 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
7832 This removes the need for a memory_full check.
7833 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
7834 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
7835 (xbm_read_bitmap_data): Change locals back to 'int', since
7836 their values must fit in 'int'.
7837 (xpm_load_image, png_load, tiff_load):
7838 Invoke x_create_x_image_and_pixmap earlier,
7839 to avoid much needless work if the image is too large.
7840 (tiff_load): Treat overly large images as if
7841 x_create_x_image_and_pixmap failed, not as malloc failures.
7842 (gs_load): Use x_check_image_size.
7844 * gtkutil.c: Omit integer casts.
7845 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
7846 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
7848 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
7850 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
7851 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
7852 would wrongly return t on a 64-bit host.
7854 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
7855 The plain *_OVERFLOW macros run afoul of GCC bug 49705
7856 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
7857 and therefore cause GCC to emit a bogus diagnostic in some cases.
7859 * image.c: Integer signedness and overflow and related fixes.
7860 This is not an exhaustive set of fixes, but it's time to
7861 record what I've got.
7862 (lookup_pixel_color, check_image_size): Remove redundant decls.
7863 (check_image_size): Don't assume that arbitrary EMACS_INT values
7864 fit in 'int', or that arbitrary 'double' values fit in 'int'.
7865 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
7866 (tiff_load, imagemagick_load_image):
7867 Check for overflow in size calculations.
7868 (x_create_x_image_and_pixmap): Remove unnecessary test for
7869 xmalloc returning NULL; that can't happen.
7870 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
7871 (xpm_color_bucket): Use better integer hashing function.
7872 (xpm_cache_color): Don't possibly over-allocate memory.
7873 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
7874 (gif_memory_source):
7875 Use ptrdiff_t, not int or size_t, to record sizes.
7876 (png_load): Don't assume values greater than 2**31 fit in 'int'.
7877 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
7878 either works, as we prefer signed integers.
7879 (tiff_read_from_memory, tiff_write_from_memory):
7880 Return tsize_t, not size_t, since that's what the TIFF API wants.
7881 (tiff_read_from_memory): Don't fail simply because the read would
7882 go past EOF; instead, return a short read.
7883 (tiff_load): Omit no-longer-needed casts.
7884 (Fimagemagick_types): Don't assume size fits into 'int'.
7886 Improve hashing quality when configured --with-wide-int.
7887 * fns.c (hash_string): New function, taken from sxhash_string.
7888 Do not discard information about ASCII character case; this
7889 discarding is no longer needed.
7890 (sxhash-string): Use it. Change sig to match it. Caller changed.
7891 * lisp.h: Declare it.
7892 * lread.c (hash_string): Remove, since we now use fns.c's version.
7893 The fns.c version returns a wider integer if --with-wide-int is
7894 specified, so this should help the quality of the hashing a bit.
7896 * emacs.c: Integer overflow minor fix.
7897 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
7898 Define only if GNU_LINUX.
7899 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
7901 * dispnew.c: Integer signedness and overflow fixes.
7902 Remove unnecessary forward decls, that were a maintenance hassle.
7903 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
7905 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
7906 (scrolling_window): Use ptrdiff_t, not int, for byte count.
7907 (prepare_desired_row, line_draw_cost):
7908 Use int, not unsigned, where either works.
7909 (save_current_matrix, restore_current_matrix):
7910 Use ptrdiff_t, not size_t, where either works.
7911 (init_display): Check for overflow more accurately, and without
7912 relying on undefined behavior.
7914 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
7915 Remove, replacing with the new symbols in lisp.h. All uses changed.
7916 * fileio.c (make_temp_name):
7917 * filelock.c (lock_file_1, lock_file):
7918 * xdisp.c (message_dolog):
7919 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
7920 Use pMd etc. instead.
7921 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
7922 replacing the pWIDE etc. symbols removed from editfns.c.
7924 * keyboard.h (num_input_events): Now uintmax_t.
7925 This is (very slightly) less likely to mess up due to wraparound.
7928 * buffer.c: Integer signedness fixes.
7929 (alloc_buffer_text, enlarge_buffer_text):
7930 Use ptrdiff_t rather than size_t when either will do, as we prefer
7933 * alloc.c: Integer signedness and overflow fixes.
7934 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
7935 (__malloc_size_t): Default to size_t, not to int.
7936 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
7937 (Fgarbage_collect, mark_object_loop_halt, mark_object):
7938 Prefer ptrdiff_t to size_t when either would do, as we prefer
7940 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
7941 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
7942 Now const. Initialize with values that are in range even if char
7944 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
7945 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
7946 These functions do the right thing with sizes > 2**32.
7947 (check_depth): Now ptrdiff_t, not int.
7948 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
7949 Adjust to new way of storing sizes. Check for size overflow bugs
7951 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
7952 slightly wrong anyway, as it missed one instance of
7953 XMALLOC_OVERRUN_CHECK_OVERHEAD.
7954 (refill_memory_reserve): Omit needless cast to size_t.
7955 (mark_object_loop_halt): Mark as externally visible.
7957 * xselect.c: Integer signedness and overflow fixes.
7958 (Fx_register_dnd_atom, x_handle_dnd_message):
7959 Use ptrdiff_t, not size_t, since we prefer signed.
7960 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
7961 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
7962 x_dnd_atoms_size and x_dnd_atoms_length.
7964 * doprnt.c: Prefer signed to unsigned when either works.
7966 * doprnt.c (doprnt):
7968 * xdisp.c (vmessage):
7969 Use ptrdiff_t, not size_t, when using or implementing doprnt,
7970 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
7971 prefer signed arithmetic to avoid comparison confusion.
7972 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
7973 but is a bit tricky.
7975 Assume freestanding C89 headers, string.h, stdlib.h.
7976 * data.c, doprnt.c, floatfns.c, print.c:
7977 Include float.h unconditionally.
7978 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
7979 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
7980 * regex.c: Likewise for stddef.h, string.h.
7981 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
7982 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
7983 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
7984 (STDC_HEADERS): Remove obsolete defines.
7985 * sysdep.c: Include limits.h unconditionally.
7987 Assume support for memcmp, memcpy, memmove, memset.
7988 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
7989 * regex.c (memcmp, memcpy):
7990 Remove; we assume C89 now.
7992 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
7993 (__malloc_safe_bcopy): Remove; no longer needed.
7995 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
7996 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
7997 well either way, and we prefer signed to unsigned.
7999 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
8001 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
8002 closes the connection while we're reading (bug#9182).
8004 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
8006 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
8007 are specified (Bug#9168).
8009 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
8011 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
8012 Found by GCC static checking and --with-wide-int on a 32-bit host.
8014 2011-07-25 Eli Zaretskii <eliz@gnu.org>
8016 * xdisp.c (compute_display_string_pos): Fix logic of caching
8017 previous display string position. Initialize cached_prev_pos to
8018 -1. Fixes slow-down at the beginning of a buffer.
8020 2011-07-24 Eli Zaretskii <eliz@gnu.org>
8022 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
8023 for attrs[LFACE_FONTSET_INDEX].
8025 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
8027 * xml.c (parse_region): Remove unused local
8028 that was recently introduced.
8030 2011-07-23 Eli Zaretskii <eliz@gnu.org>
8032 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
8033 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
8035 * xdisp.c (move_it_in_display_line_to): Record the best matching
8036 position for TO_CHARPOS while scanning the line, and restore it on
8037 exit if none of the characters scanned was an exact match.
8038 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
8039 when exact match is impossible due to invisible text, and the
8040 lines are truncated.
8042 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
8044 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
8047 2011-07-22 Eli Zaretskii <eliz@gnu.org>
8049 Fix a significant slow-down of cursor motion with C-n, C-p,
8050 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
8051 auto-repeat under bidi redisplay in fontified buffers.
8052 * xdisp.c (compute_stop_pos_backwards): New function.
8053 (next_element_from_buffer): Call compute_stop_pos_backwards to
8054 find a suitable prev_stop when we find ourselves before
8056 (reseat): Don't look for prev_stop, as that could mean a very long
8058 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
8059 <cached_disp_overlay_modiff>: Cache for last found display string
8061 (compute_display_string_pos): Return the cached position if asked
8062 about the same buffer in the same area of character positions, and
8063 the buffer wasn't changed since the time the display string
8064 position was cached.
8066 2011-07-22 Eli Zaretskii <eliz@gnu.org>
8068 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
8069 is an integer, which is important for empty lines. (Bug#9149)
8071 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
8073 * frame.c (Fmodify_frame_parameters): In tty case, update the
8074 default face if necessary (Bug#4238).
8076 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
8078 * editfns.c (Fstring_to_char): No need to explain what a character
8079 is in the docstring (Bug#6576).
8081 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
8083 * xml.c (parse_region): Make sure we always return a tree.
8085 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
8087 * xml.c (parse_region): If a document contains only comments,
8090 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
8092 * xml.c (make_dom): Return comments, too.
8094 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
8097 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
8098 and the surrounding thread.
8099 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
8100 rather than fgets, and retry after EINTR. Otherwise, 'emacs
8101 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
8103 * s/openbsd.h (BROKEN_SIGIO): Define.
8104 * unexelf.c (unexec) [__OpenBSD__]:
8105 Don't update the .mdebug section of the Alpha COFF symbol table.
8107 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
8109 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
8112 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
8114 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
8115 This fixes some race conditions on the permissions of any newly
8118 * alloc.c (valid_pointer_p): Use pipe, not open.
8119 This fixes some permissions issues when debugging.
8121 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
8122 If fchown fails to set both uid and gid, try to set just gid,
8123 as that is sometimes allowed. Adjust the file's mode to eliminate
8124 setuid or setgid bits that are inappropriate if fchown fails.
8126 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
8128 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
8129 to compare Lisp_Objects.
8130 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
8131 global_gnutls_log_level, don't mistake it for a Lisp_Object.
8132 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
8134 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
8136 * lread.c (read_integer): Unread even EOF character.
8137 (read1): Likewise. Properly record start position of symbol.
8139 * lread.c (read1): Read `#:' as empty uninterned symbol if no
8140 symbol character follows.
8142 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
8144 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
8145 This works around a problem with the previous change to Fcopy_file.
8146 Recent glibc declares fchown with __attribute__((warn_unused_result)),
8147 and without this change, GCC might complain about discarding
8148 fchown's return value.
8150 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
8152 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
8154 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
8156 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
8158 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
8160 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
8161 it's used from the C level.
8163 * process.c: Use the same condition for POLL_FOR_INPUT in both
8164 keyboard.c and process.c (bug#1858).
8166 2011-07-09 Lawrence Mitchell <wence@gmx.li>
8168 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
8169 (Fgnutls_boot): Use it.
8171 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
8173 * doc.c (Fsubstitute_command_keys): Revert last change.
8175 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
8177 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
8178 quotes the next character, and doesn't affect other longer
8179 sequences (bug#8935).
8181 * lread.c (syms_of_lread): Clarify that is isn't only
8182 `eval-buffer' and `eval-defun' that's affected by
8183 `lexical-binding' (bug#8460).
8185 2011-07-15 Eli Zaretskii <eliz@gnu.org>
8187 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
8188 bidi redisplay when a line includes both an image and is truncated.
8190 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
8192 Fix minor problems found by static checking.
8193 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
8194 (elsz): Now a signed constant, not a size_t var. We prefer signed
8195 types to unsigned, to avoid integer comparison confusion. Without
8196 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
8197 "cannot optimize loop, the loop counter may overflow", a symptom
8199 * indent.c (Fvertical_motion): Mark locals as initialized.
8200 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
8202 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
8204 * search.c (Fre_search_backward): Mention `case-fold-search' in
8205 all the re_search_* functions (bug#8138).
8207 * keyboard.c (Fopen_dribble_file): Document when the file is
8210 2011-07-14 Eli Zaretskii <eliz@gnu.org>
8212 * bidi.c (bidi_dump_cached_states): Fix format of displaying
8215 Support bidi reordering of display and overlay strings.
8216 * xdisp.c (compute_display_string_pos)
8217 (compute_display_string_end): Accept additional argument STRING.
8218 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
8219 (reseat_to_string): Initialize bidi_it->string.s and
8220 bidi_it->string.schars.
8221 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
8222 NULL (avoids a crash in bidi_paragraph_init).
8223 Initialize itb.string.lstring.
8224 (init_iterator): Call bidi_init_it only of a valid
8225 buffer position was specified. Initialize paragraph_embedding to
8227 (reseat_to_string): Initialize the bidi iterator.
8228 (display_string): If we need to ignore text properties of
8229 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
8230 original value of -1 will not work with bidi.)
8231 (compute_display_string_pos): First arg is now struct
8232 `text_pos *'; all callers changed. Support display properties on
8234 (compute_display_string_end): Support display properties on Lisp
8236 (init_iterator, reseat_1, reseat_to_string): Initialize the
8237 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
8238 when iterating on a string not from display properties).
8239 (compute_display_string_pos, compute_display_string_end):
8240 Fix calculation of the object to scan. Fixes an error when using
8242 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
8243 base_level_stop; instead, set base_level_stop to BEGV.
8244 Fixes crashes in vertical-motion.
8245 (next_element_from_buffer): Improve commentary for when
8246 the iterator is before prev_stop.
8247 (init_iterator): Initialize bidi_p from the default value of
8248 bidi-display-reordering, not from buffer-local value. Use the
8249 buffer-local value only if initializing for buffer iteration.
8250 (handle_invisible_prop): Support invisible properties on strings
8251 that are being bidi-reordered.
8252 (set_iterator_to_next): Support bidi reordering of C strings and
8254 (next_element_from_string): Support bidi reordering of Lisp
8256 (handle_stop_backwards): Support Lisp strings as well.

8722 * alloc.c (mark_buffer):
8723 * buffer.c (reset_buffer_local_variables, Fbuffer_local_variables)
8724 (clone_per_buffer_values): Don't assume that
8725 sizeof (struct buffer) is a multiple of sizeof (Lisp_Object).
8726 This isn't true in general, and it's particularly not true
8727 if Emacs is configured with --with-wide-int.
8728 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
8729 New macros, used in the buffer.c change.

8736 (store_tool_bar_style_changed): New functions.
8737 (store_monospaced_changed): Add comment. Call dpyinfo_valid.
8738 (struct xsettings): Move font inside HAVE_XFT.
8739 (GSETTINGS_TOOL_BAR_STYLE, GSETTINGS_FONT_NAME): New defines.
8740 (GSETTINGS_MONO_FONT): Rename from SYSTEM_MONO_FONT.

8743 Check for changes in GSETTINGS_TOOL_BAR_STYLE and GSETTINGS_FONT_NAME
8745 (GCONF_TOOL_BAR_STYLE, GCONF_FONT_NAME): New defines.
8746 (GCONF_MONO_FONT): Rename from SYSTEM_MONO_FONT. Move inside HAVE_XFT.
8747 (something_changed_gconfCB): Rename from something_changedCB.
8748 Check for changes in GCONF_TOOL_BAR_STYLE and GCONF_FONT_NAME also.
8749 (parse_settings): Move check for font inside HAVE_XFT.
8750 (read_settings, apply_xft_settings): Add comment.
8751 (read_and_apply_settings): Add comment. Call map_tool_bar_style and

8763 2011-07-05 Paul Eggert <eggert@cs.ucla.edu>
8765 Random fixes. E.g., (random) never returned negative values.
8766 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
8767 subseconds part to the entropy, as that's a bit more random.
8768 Prefer signed to unsigned, since the signedness doesn't matter and
8769 in general we prefer signed. When given a limit, use a
8770 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
8771 latter isn't right if USE_2_TAGS_FOR_INTS.
8772 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
8773 not 0..VALMASK. Don't discard "excess" bits that random () returns.
8775 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>

8783 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
8785 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
8786 This is more efficient than Ffile_directory_p and avoids a minor race.
8788 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
8790 * buffer.c (Foverlay_put): Say what the return value is
8793 * fileio.c (barf_or_query_if_file_exists): Check first if the file
8794 is a directory before asking whether to use the file name
8796 (barf_or_query_if_file_exists): Make the "File is a directory"
8797 error be more correct.
8799 * fns.c (Frequire): Remove the mention of the .gz files, since
8800 that's installation-specific, but keep the mention of
8801 `get-load-suffixes'.
8803 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
8805 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.
8806 Report string overflow if the output is too long.
8808 2011-07-04 Juanma Barranquero <lekktu@gmail.com>
8810 * gnutls.c (Fgnutls_boot): Don't mention :verify-error.
8811 (syms_of_gnutls): Remove duplicate DEFSYM for
8812 Qgnutls_bootprop_verify_hostname_error, an error for
8813 Qgnutls_bootprop_verify_error (which is no longer used).
8815 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
8816 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
8817 Also (re)move comments that are misplaced or no longer relevant.
8819 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
8821 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).
8823 2011-07-03 Chong Yidong <cyd@stupidchicken.com>
8825 * xfaces.c (Finternal_merge_in_global_face): Modify the foreground
8826 and background color parameters if they have been changed.
8828 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>

8850 (Frequire): Mention get-load-suffixes.
8852 2011-07-02 Martin Rudalics <rudalics@gmx.at>
8854 * window.h (window): Remove clone_number slot.

8880 (syms_of_keymap): Defsubr make-composed-keymap.
8881 * keyboard.c (menu_bar_items): Use map_keymap_canonical.
8882 (parse_menu_item): Trivial simplification.
8884 2011-07-01 Glenn Morris <rgm@gnu.org>
8886 * Makefile.in (SETTINGS_LIBS): Fix typo.
8888 2011-07-01 Kazuhiro Ito <kzhr@d1.dion.ne.jp> (tiny patch)
8890 * coding.c (Fencode_coding_string): Record the last coding system
8891 used, as the function doc string says (bug#8738).

8913 (wait_reading_process_output): Add defined (HAVE_GSETTINGS) for
8916 2011-07-01 Paul Eggert <eggert@cs.ucla.edu>
8918 * eval.c (struct backtrace): Simplify and port the data structure.
8919 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
8920 signed bit field, as this assumption is not portable and it makes
8921 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
8922 "char debug_on_exit : 1" as this is not portable either; instead,
8923 use the portable "unsigned int debug_on_exit : 1". Remove unused
8924 member evalargs. Remove obsolete comments about cc bombing out.
8926 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

9088 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
9090 Integer and buffer overflow fixes (Bug#8873).
9092 * print.c (printchar, strout): Check for string overflow.
9093 (PRINTPREPARE, printchar, strout):
9094 Don't set size unless allocation succeeds.
9096 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
9097 for sizes. Check for string overflow more accurately.

9110 * lread.c: Integer overflow fixes.
9111 (read_integer): Radix is now EMACS_INT, not int,
9112 to improve quality of diagnostics for out-of-range radices.

9114 (read1): Check for integer overflow in radices, and in
9115 read-circle numbers.
9116 (read_escape): Avoid int overflow.
9117 (Fload, openp, read_buffer_size, read1)
9118 (substitute_object_recurse, read_vector, read_list, map_obarray):

9139 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
9141 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
9142 The following patches are for when GLYPH_DEBUG && !XASSERT.
9143 * dispextern.h (trace_redisplay_p, dump_glyph_string):
9144 * dispnew.c (flush_stdout):
9145 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
9146 Mark as externally visible.
9147 * dispnew.c (check_window_matrix_pointers): Now static.
9148 * dispnew.c (window_to_frame_vpos):
9149 * xfns.c (unwind_create_frame):
9150 * xterm.c (x_check_font): Remove unused local.
9151 * scroll.c (CHECK_BOUNDS):
9152 * xfaces.c (cache_fache): Rename local to avoid shadowing.
9153 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
9154 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
9155 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
9156 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
9158 (debug_method_add): Use va_list and vsprintf rather than relying
9159 on undefined behavior with wrong number of arguments.
9160 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
9161 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
9162 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
9163 since we're not interested in debugging glyphs with old libraries.
9164 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
9165 GCC 4.6.0's static checking.
9167 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
9169 Integer overflow and signedness fixes (Bug#8873).
9170 A few related buffer overrun fixes, too.
9172 * font.c (font_score): Use EMACS_INT, not int, to store XINT value.
9174 * dispextern.h (struct face.stipple):
9175 * image.c (x_bitmap_height, x_bitmap_width, x_bitmap_pixmap)
9176 (x_bitmap_mask, x_allocate_bitmap_record)
9177 (x_create_bitmap_from_data, x_create_bitmap_from_file)
9178 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
9179 (x_create_bitmap_from_xpm_data):
9180 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
9181 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
9183 * xfaces.c (load_pixmap):
9184 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
9185 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
9186 (.bitmaps_last, struct x_output.icon_bitmap):
9187 Use ptrdiff_t, not int, for bitmap indexes.
9188 (x_allocate_bitmap_record): Check for size overflow.
9189 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
9191 Use ptrdiff_t, not int, for overlay counts.
9192 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
9193 * editfns.c (overlays_around, get_pos_property):
9194 * textprop.c (get_char_property_and_overlay):
9195 * xdisp.c (next_overlay_change, note_mouse_highlight):
9196 * xfaces.c (face_at_buffer_position):
9197 * buffer.c (OVERLAY_COUNT_MAX): New macro.
9198 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
9199 (Fnext_overlay_change, Fprevious_overlay_change)
9200 (mouse_face_overlay_overlaps, Foverlays_in):
9201 Use ptrdiff_t, not int, for sizes.
9202 (overlays_at, overlays_in): Check for size-calculation overflow.
9204 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
9206 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
9207 (x_session_initialize): Do not assume string length fits in int.
9209 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
9210 This is unlikely, but can occur if DPI is outlandish.
9212 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
9213 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
9215 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
9216 * xrdb.c (magic_file_p, search_magic_path):
9217 Omit last arg SUFFIX; it was always 0. All callers changed.
9218 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
9220 * xfont.c (xfont_match): Avoid need for strlen.
9222 * xfns.c: Don't assume strlen fits in int.
9223 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
9225 * xdisp.c (message_log_check_duplicate): Return intmax_t,
9226 not unsigned long, as we prefer signed integers. All callers changed.
9227 Detect integer overflow in repeat count.
9228 (message_dolog): Don't assume print length fits in 39 bytes.
9229 (display_mode_element): Don't assume strlen fits in int.
9231 * termcap.c: Don't assume sizes fit in int and never overflow.
9232 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
9233 (gobble_line): Check for size-calculation overflow.
9235 * minibuf.c (Fread_buffer):
9236 * lread.c (intern, intern_c_string):
9237 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
9238 Don't assume string length fits in int.
9240 * keyboard.c (parse_tool_bar_item):
9241 * gtkutil.c (style_changed_cb): Avoid need for strlen.
9243 * font.c: Don't assume string length fits in int.
9244 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
9245 Use ptrdiff_t, not int.
9246 (font_intern_prop): Don't assume string length fits in int.
9247 Don't assume integer property fits in fixnum.
9248 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
9250 * filelock.c: Fix some buffer overrun and integer overflow issues.
9251 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
9252 Reformulate so as not to need the command string.
9253 Invoke gzip -cd rather than gunzip, as it's more portable.
9254 (lock_info_type, lock_file_1, lock_file):
9255 Don't assume pid_t and time_t fit in unsigned long.
9256 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
9257 (current_lock_owner): Prefer signed type for sizes.
9258 Use memcpy, not strncpy, where memcpy is what is really wanted.
9259 Don't assume (via atoi) that time_t and pid_t fit in int.
9260 Check for time_t and/or pid_t out of range, e.g., via a network share.
9261 Don't alloca where an auto var works fine.
9263 * fileio.c: Fix some integer overflow issues.
9264 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
9265 Don't assume string length fits in int.
9266 (directory_file_name): Don't assume string length fits in long.
9267 (make_temp_name): Don't assume pid fits in int, or that its print
9268 length is less than 20.
9270 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
9272 * coding.c (make_subsidiaries): Don't assume string length fits in int.
9274 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
9276 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
9277 We prefer signed integers, even for size calculations.
9279 * emacs.c: Don't assume string length fits in 'int'.
9280 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
9281 (main): Don't invoke strlen when not needed.
9283 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
9284 (XD_DEBUG_MESSAGE): Don't waste a byte.
9286 * callproc.c (getenv_internal_1, getenv_internal)
9288 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
9290 * lread.c (invalid_syntax): Omit length argument.
9291 All uses changed. This doesn't fix a bug, but it simplifies the
9292 code away from its former Hollerith-constant appearance, and it's
9293 one less 'int' to worry about when looking at integer-overflow issues.
9294 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
9296 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
9297 This didn't break anything, but it didn't help either.
9298 It's confusing to put a bogus integer in a place where the actual
9299 value does not matter.
9300 (LIST_END_P): Remove unused macro and its bogus comment.
9301 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
9303 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
9304 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
9306 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
9307 We prefer signed types, and the value cannot exceed the EMACS_INT
9308 range anyway (because otherwise the length would not be representable).
9309 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
9310 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
9311 This avoids a GCC warning when WIDE_EMACS_INT.
9313 * indent.c (sane_tab_width): New function.
9314 (current_column, scan_for_column, Findent_to, position_indentation)
9315 (compute_motion): Use it. This is just for clarity.
9316 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
9318 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
9320 * lisp.h (lint_assume): New macro.
9321 * composite.c (composition_gstring_put_cache):
9322 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
9324 * editfns.c, insdel.c:
9325 Omit unnecessary forward decls, to simplify future changes.
9327 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
9329 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
9331 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
9332 Use much-faster test for byte-length change.
9333 Don't assume string byte-length fits in 'int'.
9334 Check that character arg fits in 'int'.
9335 (mapcar1): Declare byte as byte, for clarity.
9337 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
9339 * fns.c (concat): Catch string overflow earlier.
9340 Do not rely on integer wraparound.
9342 * dispextern.h (struct it.overlay_strings_charpos)
9343 (struct it.selective): Now EMACS_INT, not int.
9344 * xdisp.c (forward_to_next_line_start)
9345 (back_to_previous_visible_line_start)
9346 (reseat_at_next_visible_line_start, next_element_from_buffer):
9347 Don't arbitrarily truncate the value of 'selective' to int.
9349 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
9351 * composite.c: Don't truncate sizes to 'int'.
9352 (composition_gstring_p, composition_reseat_it)
9353 (composition_adjust_point): Use EMACS_INT, not int.
9354 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
9355 not EMACS_UINT, for indexes.
9357 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
9359 * buffer.c: Include <verify.h>.
9360 (struct sortvec.priority, struct sortstr.priority):
9361 Now EMACS_INT, not int.
9362 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
9363 (struct sortstr.size, record_overlay_string)
9364 (struct sortstrlist.size, struct sortlist.used):
9365 Don't truncate size to int.
9366 (record_overlay_string): Check for size-calculation overflow.
9367 (init_buffer_once): Check at compile-time, not run-time.
9369 2011-06-22 Jim Meyering <meyering@redhat.com>
9371 Don't leak an XBM-image-sized buffer
9372 * image.c (xbm_load): Free the image buffer after using it.
9374 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
9377 * composite.c (find_automatic_composition): Omit needless 'return 0;'
9378 that Sun C diagnosed.
9379 * fns.c (secure_hash): Fix pointer signedness issue.
9380 * intervals.c (static_offset_intervals): New function.
9381 (offset_intervals): Use it.
9383 2011-06-21 Leo Liu <sdl.web@gmail.com>
9386 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
9389 * fns.c (secure_hash): Rename from crypto_hash_function and change
9390 the first arg to accept symbols.
9391 (Fsecure_hash): New primitive.
9392 (syms_of_fns): New symbols.
9394 2011-06-20 Deniz Dogan <deniz@dogan.se>
9396 * process.c (Fset_process_buffer): Clarify return value in
9399 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
9401 * dispnew.c (add_window_display_history): Use BVAR.
9403 * xdisp.c (debug_method_add): Use BVAR.
9404 (check_window_end, dump_glyph_matrix, dump_glyph)
9405 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
9407 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
9410 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
9411 check till after the cache is created in init_frame_faces.
9413 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
9415 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
9417 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
9419 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
9420 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
9421 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
9423 Improve buffer-overflow checking (Bug#8873).
9424 * fileio.c (Finsert_file_contents):
9425 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
9426 Remove the old (too-loose) buffer overflow checks.
9427 They weren't needed, since make_gap checks for buffer overflow.
9428 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
9429 The old code merely checked for Emacs fixnum overflow, and relied
9430 on undefined (wraparound) behavior. The new code avoids undefined
9431 behavior, and also checks for ptrdiff_t and/or size_t overflow.
9433 * editfns.c (Finsert_char): Don't dump core with very negative counts.
9434 Tune. Don't use wider integers than needed. Don't use alloca.
9435 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
9437 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
9439 * insdel.c, lisp.h (buffer_overflow): New function.
9440 (insert_from_buffer_1, replace_range, replace_range_2):
9441 * insdel.c (make_gap_larger):
9442 * editfns.c (Finsert_char):
9443 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
9445 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
9447 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
9449 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
9451 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
9452 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
9454 * fileio.c: Don't assume EMACS_INT fits in off_t.
9455 (emacs_lseek): New static function.
9456 (Finsert_file_contents, Fwrite_region): Use it.
9457 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
9459 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
9461 * fns.c: Don't overflow int when computing a list length.
9462 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
9463 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
9464 truncation on 64-bit hosts. Check for QUIT every
9465 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
9466 faster and is responsive enough.
9467 (Flength): Report an error instead of overflowing an integer.
9468 (Fsafe_length): Return a float if the value is not representable
9469 as a fixnum. This shouldn't happen except in contrived situations.
9470 (Fnthcdr, Fsort): Don't assume list length fits in int.
9471 (Fcopy_sequence): Don't assume vector length fits in int.
9473 * alloc.c: Check that resized vectors' lengths fit in fixnums.
9474 (header_size, word_size): New constants.
9475 (allocate_vectorlike): Don't check size overflow here.
9476 (allocate_vector): Check it here instead, since this is the only
9477 caller of allocate_vectorlike that could cause overflow.
9478 Check that the new vector's length is representable as a fixnum.
9480 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
9481 The previous code was bogus. For example, next_almost_prime (32)
9482 returned 39, which is undesirable as it is a multiple of 3; and
9483 next_almost_prime (24) returned 25, which is a multiple of 5 so
9484 why was the code bothering to check for multiples of 7?
9486 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
9488 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
9490 Variadic C functions now count arguments with ptrdiff_t.
9491 This partly undoes my 2011-03-30 change, which replaced int with size_t.
9492 Back then I didn't know that the Emacs coding style prefers signed int.
9493 Also, in the meantime I found a few more instances where arguments
9494 were being counted with int, which may truncate counts on 64-bit
9495 machines, or EMACS_INT, which may be unnecessarily wide.
9496 * lisp.h (struct Lisp_Subr.function.aMANY)
9497 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
9498 Arg counts are now ptrdiff_t, not size_t.
9499 All variadic functions and their callers changed accordingly.
9500 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
9501 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
9502 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
9503 * callint.c (Fcall_interactively): Check arg count for overflow,
9504 to avoid potential buffer overrun. Use signed char, not 'int',
9505 for 'varies' array, so that we needn't bother to check its size
9506 calculation for overflow.
9507 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
9508 * eval.c (apply_lambda):
9509 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
9510 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
9511 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
9513 * callint.c (Fcall_interactively): Don't use index var as event count.
9515 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
9516 * mem-limits.h (SIZE): Remove; no longer used.
9518 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
9520 Remove unnecessary casts.
9521 * xterm.c (x_term_init):
9522 * xfns.c (x_set_border_pixel):
9523 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
9524 These aren't needed now that we assume ANSI C.
9526 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
9527 It's more likely to cause problems (due to unsigned overflow)
9530 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
9532 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
9534 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
9536 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
9538 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
9540 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
9542 GLYPH_CODE_FACE returns EMACS_INT, not int.
9543 * dispextern.h (merge_faces):
9544 * xfaces.c (merge_faces):
9545 * xdisp.c (get_next_display_element, next_element_from_display_vector):
9546 Don't assume EMACS_INT fits in int.
9548 * character.h (CHAR_VALID_P): Remove unused parameter.
9549 * fontset.c, lisp.h, xdisp.c: All uses changed.
9551 * editfns.c (Ftranslate_region_internal): Omit redundant test.
9553 * fns.c (concat): Minor tuning based on overflow analysis.
9554 This doesn't fix any bugs. Use int to hold character, instead
9555 of constantly refetching from Emacs object. Use XFASTINT, not
9556 XINT, for value known to be a character. Don't bother comparing
9557 a single byte to 0400, as it's always less.
9559 * floatfns.c (Fexpt):
9560 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
9562 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
9565 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
9567 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
9568 Without this fix, on a 64-bit host (aset S 0 4294967386) would
9569 incorrectly succeed when S was a string, because 4294967386 was
9570 truncated before it was used.
9572 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
9573 Otherwise, an out-of-range integer could cause undefined behavior
9576 * composite.c: Use int, not EMACS_INT, for characters.
9577 (fill_gstring_body, composition_compute_stop_pos): Use int, not
9578 EMACS_INT, for values that are known to be in character range.
9579 This doesn't fix any bugs but is the usual style inside Emacs and
9580 may generate better code on 32-bit machines.
9582 Make sure a 64-bit char is never passed to ENCODE_CHAR.
9583 This is for reasons similar to the recent CHAR_STRING fix.
9584 * charset.c (Fencode_char): Check that character arg is actually
9585 a character. Pass an int to ENCODE_CHAR.
9586 * charset.h (ENCODE_CHAR): Verify that the character argument is no
9587 wider than 'int', as a compile-time check to prevent future regressions
9590 * character.c (char_string): Remove unnecessary casts.
9592 Make sure a 64-bit char is never passed to CHAR_STRING.
9593 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
9594 by silently ignoring the top 32 bits, allowing some values
9595 that were far too large to be valid characters.
9596 * character.h: Include <verify.h>.
9597 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
9598 arguments are no wider than unsigned, as a compile-time check
9599 to prevent future regressions in this area.
9601 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
9602 (Fsubst_char_in_region):
9604 * xdisp.c (decode_mode_spec_coding):
9605 Adjust to CHAR_STRING's new requirement.
9606 * editfns.c (Finsert_char, Fsubst_char_in_region):
9607 * fns.c (concat): Check that character args are actually
9608 characters. Without this test, these functions did the wrong
9609 thing with wildly out-of-range values on 64-bit hosts.
9611 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
9612 These casts should not be needed on 32-bit hosts, either.
9613 * keyboard.c (read_char):
9614 * lread.c (Fload): Remove casts to unsigned.
9616 * lisp.h (UNSIGNED_CMP): New macro.
9617 This fixes comparison bugs on 64-bit hosts.
9618 (ASCII_CHAR_P): Use it.
9619 * casefiddle.c (casify_object):
9620 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
9621 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
9622 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
9623 * dispextern.h (FACE_FROM_ID):

9678 * alloc.c: Catch some string size overflows that we were missing.
9679 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
9680 for convenience in STRING_BYTES_MAX.
9681 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
9682 The definition here is exact; the one in lisp.h was approximate.
9683 (allocate_string_data): Check for string overflow. This catches
9684 some instances we weren't catching before. Also, it catches
9685 size_t overflow on (unusual) hosts where SIZE_MAX <= min
9686 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
9687 and ptrdiff_t and EMACS_INT are both 64 bits.
9689 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
9690 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
9691 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.

10268 instead of using explicit *_CHAR codes.
10269 (bidi_resolve_explicit, bidi_resolve_weak):

10278 (bidi_level_of_next_char): Don't try to lookup the cache for the
10279 next/previous character if nothing is cached there yet, or if we
10280 were just reseat()'ed to a new position.
10282 * xdisp.c (set_cursor_from_row): Set start and stop points
10283 according to the row's direction when priming the loop that looks
10284 for the glyph on which to display cursor.

10286 (display_prop_intangible_p): Reimplement to call
10287 handle_display_spec instead of single_display_spec_intangible_p.
10288 Accept 3 additional arguments needed by handle_display_spec.
10289 This fixes incorrect cursor motion across display property with complex

10292 lists with the argument STRING its top-level element.
10293 (display_prop_string_p): Fix the condition for processing a

10297 (compute_display_string_pos): Accept additional argument
10298 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
10299 value of a `display' property is a "replacing spec".
10300 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
10301 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
10302 the display property, but just return a value indicating whether
10303 the display property will replace the characters it covers.
10304 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
10305 frame_window_p members of struct bidi_it.

10329 All callers changed. (Bug#8762)
10331 * gnutls.c: Use Emacs's memory allocators.
10332 Without this change, the gnutls library would invoke malloc etc.
10333 directly, which causes problems on non-SYNC_INPUT hosts, and which
10334 runs afoul of improving memory_full behavior. (Bug#8761)
10335 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
10336 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
10337 xfree instead of the default malloc, realloc, free.
10338 (Fgnutls_boot): No need to check for memory allocation failure,
10339 since xmalloc does that for us.

10362 for hashes and hash indexes, instead of 'unsigned' and 'int'.
10363 * alloc.c (allocate_vectorlike):
10364 Check for overflow in vector size calculations.
10365 * ccl.c (ccl_driver):
10366 Check for overflow when converting EMACS_INT to int.

10368 need to be updated by these changes.
10369 * fns.c (make_hash_table, maybe_resize_hash_table):
10370 Check for integer overflow with large hash tables.
10371 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
10372 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
10373 (SXHASH_REDUCE): New macro.
10374 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
10375 Use it instead of discarding useful hash info with large hash values.
10376 (sxhash_float): New function.
10377 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
10378 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
10379 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
10380 Rewrite to use FIXNUM_BITS, as this simplifies things.
10381 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
10382 Adjust signatures to match updated version of code.
10383 (consing_since_gc): Now EMACS_INT, since a single hash table can
10384 use more than INT_MAX bytes.

10433 Make it possible to run ./temacs.
10435 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
10436 syms_of_callproc does the same thing. Remove test for

10497 * fns.c (to_uchar): Define.
10498 (crypto_hash_function): Use it to convert some newly-signed

10511 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
10512 to hold a serial number that is too large for a fixnum.
10513 (Fdbus_method_return_internal, Fdbus_method_error_internal):
10514 Check for serial numbers out of range. Decode any serial number
10515 that was so large that it became a float. (Bug#8722)
10517 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
10518 (Fdbus_call_method, Fdbus_call_method_asynchronously):
10519 Use XFASTINT rather than XUINT when numbers are nonnegative.
10520 (xd_append_arg, Fdbus_method_return_internal):
10521 (Fdbus_method_error_internal): Likewise. Also, for unsigned
10522 arguments, check that Lisp number is nonnegative, rather than
10523 silently wrapping negative numbers around. (Bug#8722)
10524 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
10527 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
10529 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
10531 ccl: Add integer overflow checks.
10532 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
10533 (IN_INT_RANGE): New macros.
10534 (ccl_driver): Use them to check for integer overflow when
10535 decoding a CCL program. Many of the new checks are whether XINT (x)
10536 fits in int; it doesn't always, on 64-bit hosts. The new version
10537 doesn't catch all possible integer overflows, but it's an
10538 improvement. (Bug#8719)
10540 * alloc.c (make_event_array): Use XINT, not XUINT.
10541 There's no need for unsigned here.
10543 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
10544 This follows up to the 2011-05-06 change that substituted uintptr_t
10545 for EMACS_INT. This case wasn't caught back then.
10547 Rework Fformat to avoid integer overflow issues.
10548 * editfns.c: Include <float.h> unconditionally, as it's everywhere
10549 now (part of C89). Include <verify.h>.
10550 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
10551 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
10552 (Fformat): Avoid the prepass trying to compute sizes; it was only
10553 approximate and thus did not catch overflow reliably. Instead, walk
10554 through the format just once, formatting and computing sizes as we go,
10555 checking for integer overflow at every step, and allocating a larger
10556 buffer as needed. Keep track separately whether the format is
10557 multibyte. Keep only the most-recently calculated precision, rather
10558 than them all. Record whether each argument has been converted to
10559 string. Use EMACS_INT, not int, for byte and char and arg counts.
10560 Support field widths and precisions larger than INT_MAX. Avoid
10561 sprintf's undefined behavior with conversion specifications such as %#d
10562 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
10563 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
10564 formatting out-of-range floating point numbers with int
10565 formats. (Bug#8668)
10567 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
10569 * data.c: Avoid integer truncation in expressions involving floats.
10570 * data.c: Include <intprops.h>.
10571 (arith_driver): When there's an integer overflow in an expression
10572 involving floating point, convert the integers to floating point
10573 so that the resulting value does not suffer from catastrophic
10574 integer truncation. For example, on a 64-bit host (* 4
10575 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
10576 Do not rely on undefined behavior after integer overflow.
10578 merge count_size_as_multibyte, parse_str_to_multibyte
10579 * character.c, character.h (count_size_as_multibyte):
10580 Rename from parse_str_to_multibyte; all uses changed.
10581 Check for integer overflow.
10582 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
10583 since it's now a duplicate of the other. This is more of
10584 a character than a buffer op, so better that it's in character.c.
10585 * fns.c, print.c: Adjust to above changes.
10587 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
10589 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
10591 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
10593 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
10594 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
10595 (x_clipboard_manager_save): Now static.
10596 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
10598 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
10599 (crypto_hash_function): Now static.
10600 Fix pointer signedness problems. Avoid unnecessary initializations.
10602 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
10604 * termhooks.h (Vselection_alist): Make it terminal-local.
10606 * terminal.c (create_terminal): Initialize it.
10608 * xselect.c: Support for clipboard managers.
10609 (Vselection_alist): Move to termhooks.h as terminal-local var.
10610 (LOCAL_SELECTION): New macro.
10611 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
10612 (symbol_to_x_atom): Remove gratuitous arg.
10613 (x_handle_selection_request, lisp_data_to_selection_data)
10614 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
10615 (x_own_selection, x_get_local_selection, x_convert_selection):
10616 New arg, specifying work frame. Use terminal-local Vselection_alist.
10617 (some_frame_on_display): Delete unused function.
10618 (Fx_own_selection_internal, Fx_get_selection_internal)
10619 (Fx_disown_selection_internal, Fx_selection_owner_p)
10620 (Fx_selection_exists_p): New optional frame arg.
10621 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
10622 (x_handle_selection_clear): Don't treat other terminals with the
10623 same keyboard specially. Use the terminal-local Vselection_alist.
10624 (x_clear_frame_selections): Use Frun_hook_with_args.
10626 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
10628 * xterm.h: Add support for those atoms.
10630 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
10632 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
10633 (converted_selections, conversion_fail_tag): New global variables.
10634 (x_selection_request_lisp_error): Free the above.
10635 (x_get_local_selection): Remove unnecessary code.
10636 (x_reply_selection_request): Args changed; handle arbitrary array
10637 of converted selections stored in converted_selections.
10638 Separate the XChangeProperty and SelectionNotify steps.
10639 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
10640 (x_convert_selection): New function.
10641 (x_handle_selection_event): Simplify.
10642 (x_get_foreign_selection): Don't ignore incoming requests while
10643 waiting for an answer; this will fail when we implement
10644 SAVE_TARGETS, and seems unnecessary anyway.
10645 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
10646 (Vx_sent_selection_functions): Doc fix.
10648 2011-05-26 Leo Liu <sdl.web@gmail.com>
10650 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
10652 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10654 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
10656 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
10657 for fringe update if it has periodic bitmap.
10658 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
10659 and fringe_bitmap_periodic_p.
10661 * fringe.c (get_fringe_bitmap_data): New function.
10662 (draw_fringe_bitmap_1, update_window_fringes): Use it.
10663 (update_window_fringes): Record periodicity of fringe bitmap in glyph
10664 row. Mark glyph row for fringe update if periodicity changed.
10666 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
10667 for fringe update unless it has periodic bitmap.
10669 2011-05-25 Kenichi Handa <handa@m17n.org>
10671 * xdisp.c (get_next_display_element): Set correct it->face_id for
10672 a static composition.
10674 2011-05-24 Leo Liu <sdl.web@gmail.com>
10677 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
10679 * fns.c (crypto_hash_function, Fsha1): New function.
10680 (Fmd5): Use crypto_hash_function.
10681 (syms_of_fns): Add Ssha1.
10683 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
10685 * gnutls.c: Remove unused macros.
10686 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
10687 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
10688 Remove macros that are defined and never used.
10689 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
10691 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
10693 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
10694 (Fx_get_selection_internal): Minor cleanup.
10695 (Fx_own_selection_internal): Rename arguments for consistency with
10698 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
10700 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
10702 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
10704 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
10706 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10708 * dispnew.c (scrolling_window): Don't exclude the case that the
10709 last enabled row in the desired matrix touches the bottom boundary.
10711 2011-05-21 Glenn Morris <rgm@gnu.org>
10713 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
10714 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
10715 and add some more files.
10717 2011-05-20 Eli Zaretskii <eliz@gnu.org>
10719 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
10720 report_file_error introduced by the change from 2011-05-07.
10722 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
10724 * systime.h (Time): Define only if emacs is defined.
10725 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
10726 where the include path doesn't have X11/X.h by default. See
10727 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
10729 2011-05-20 Kenichi Handa <handa@m17n.org>
10731 * composite.c (find_automatic_composition): Fix previous change.
10733 2011-05-20 Glenn Morris <rgm@gnu.org>
10735 * lisp.mk: New file, split from Makefile.in.
10736 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
10737 (shortlisp): Remove.
10738 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
10740 2011-05-19 Glenn Morris <rgm@gnu.org>
10742 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
10743 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
10744 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
10745 (lisp): Set the order to that of loadup.el.
10746 (shortlisp): Make it a copy of $lisp.
10747 (SOME_MACHINE_LISP): Remove.
10748 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
10749 Use just $shortlisp, not $SOME_MACHINE_LISP too.
10751 2011-05-18 Kenichi Handa <handa@m17n.org>
10753 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
10754 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
10755 (find_automatic_composition): Mostly rewrite for efficiency.
10757 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
10759 * makefile.w32-in: Update dependencies.
10761 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
10763 * menu.c: Include limits.h (fixes the MS-Windows build broken by
10764 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
10766 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
10768 Fix some integer overflow issues, such as string length overflow.
10770 * insdel.c (count_size_as_multibyte): Check for string overflow.
10772 * character.c (lisp_string_width): Check for string overflow.
10773 Use EMACS_INT, not int, for string indexes and lengths; in
10774 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
10775 the resulting string length overflows an EMACS_INT; instead,
10776 report a string overflow if no precision given. When checking for
10777 precision exhaustion, use a check that cannot possibly have
10778 integer overflow. (Bug#8675)
10779 * character.h (lisp_string_width): Adjust to new signature.
10781 * alloc.c (string_overflow): New function.
10782 (Fmake_string): Use it. This doesn't change behavior, but saves
10783 a few bytes and will simplify future changes.
10784 * character.c (string_escape_byte8): Likewise.
10785 * lisp.h (string_overflow): New decl.
10787 Fixups, following up to the user-interface timestamp change.
10788 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
10789 for UI timestamps, instead of unsigned long.
10790 * msdos.c (mouse_get_pos): Likewise.
10791 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
10792 * w32gui.h (Time): Define by including "systime.h" rather than by
10793 declaring it ourselves. (Bug#8664)
10795 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
10796 * image.c (clear_image_cache): Likewise.
10798 * term.c (term_mouse_position): Don't assume time_t wraparound.
10800 Be more systematic about user-interface timestamps.
10801 Before, the code sometimes used 'Time', sometimes 'unsigned long',
10802 and sometimes 'EMACS_UINT', to represent these timestamps.
10803 This change causes it to use 'Time' uniformly, as that's what X uses.
10804 This makes the code easier to follow, and makes it easier to catch
10805 integer overflow bugs such as Bug#8664.
10806 * frame.c (Fmouse_position, Fmouse_pixel_position):
10807 Use Time, not unsigned long, for user-interface timestamps.
10808 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
10809 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
10810 * keyboard.h (last_event_timestamp): Likewise.
10811 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
10812 * menu.h (xmenu_show): Likewise.
10813 * term.c (term_mouse_position): Likewise.
10814 * termhooks.h (struct input_event.timestamp): Likewise.
10815 (struct terminal.mouse_position_hook): Likewise.
10816 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
10817 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
10818 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
10819 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
10820 what it was before.
10821 * menu.h, termhooks.h: Include "systime.h", for Time.
10823 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
10824 Don't assume that the difference between two unsigned long values
10825 can fit into an integer. At this point, we know button_down_time
10826 <= event->timestamp, so the difference must be nonnegative, so
10827 there's no need to cast the result if double-click-time is
10828 nonnegative, as it should be; check that it's nonnegative, just in
10829 case. This bug is triggered when events are more than 2**31 ms
10830 apart (about 25 days). (Bug#8664)
10832 * xselect.c (last_event_timestamp): Remove duplicate decl.
10833 (x_own_selection): Remove needless cast to unsigned long.
10835 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
10836 that always fit in int. Use a sentinel instead of a counter, to
10837 avoid a temp and to allay GCC's concerns about possible int overflow.
10838 * frame.h (struct frame): Use int for menu_bar_items_used
10839 instead of EMACS_INT, since it always fits in int.
10841 * menu.c (grow_menu_items): Check for int overflow.
10843 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
10845 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
10846 Before, the code was not consistent. These values cannot exceed
10847 2**31 - 1 so there's no need to make them unsigned.
10848 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
10849 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
10850 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
10852 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
10854 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
10855 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
10856 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
10857 presumably because the widths might not match.
10859 * window.c (size_window): Avoid needless test at loop start.
10861 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
10863 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
10865 2011-05-12 Drew Adams <drew.adams@oracle.com>
10867 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
10869 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10871 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
10872 `width' to `bar_area_x' and `bar_area_width', respectively.
10873 (x_scroll_run): Take account of fringe background extension.
10875 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
10876 Rename local vars `left' and `width' to `bar_area_x' and
10877 `bar_area_width', respectively.
10878 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
10879 background extension.
10881 2011-05-10 Jim Meyering <meyering@redhat.com>
10883 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
10885 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
10887 * image.c (Finit_image_library): Return t for built-in image types,
10888 like pbm and xbm. (Bug#8640)
10890 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
10892 * w32menu.c (set_frame_menubar): Fix submenu allocation.
10894 2011-05-07 Eli Zaretskii <eliz@gnu.org>
10896 * w32console.c (Fset_screen_color): Doc fix.
10897 (Fget_screen_color): New function.
10898 (syms_of_ntterm): Defsubr it.
10900 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
10901 unlink the temporary file if Fcall_process didn't create it in the
10903 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
10904 child process will be redirected to a file specified with `:file'.
10905 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
10906 cue to call_process_cleanup not to close that handle.
10908 2011-05-07 Ben Key <bkey76@gmail.com>
10910 * makefile.w32-in: The bootstrap-temacs rule now makes use of
10911 one of two shell specific rules, either bootstrap-temacs-CMD or
10912 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
10913 to the previous implementation of the bootstrap-temacs rule.
10914 The bootstrap-temacs-CMD rule is similar to the previous
10915 implementation of the bootstrap-temacs rule except that it
10916 makes use of the ESC_CFLAGS variable instead of the CFLAGS
10919 These changes, along with some changes to nt/configure.bat,
10920 nt/gmake.defs, and nt/nmake.defs, are required to extend my
10921 earlier fix to add support for --cflags and --ldflags options
10922 that include quotes so that it works whether make uses cmd or
10925 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
10927 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
10928 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
10930 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
10931 a string. Handle both cases.
10932 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
10933 (Fdbus_register_method): Use Qinvalid_function.
10935 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
10937 * makefile.w32-in: Update dependencies.
10938 (LISP_H): Add inttypes.h and stdin.h.
10939 (PROCESS_H): Add unistd.h.
10941 2011-05-06 Eli Zaretskii <eliz@gnu.org>
10943 * lread.c: Include limits.h (fixes the MS-Windows build broken by
10944 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
10946 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
10948 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
10950 * term.c (vfatal): Remove stray call to va_end.
10951 It's not needed and the C Standard doesn't allow it here anyway.
10953 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
10954 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
10956 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
10959 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
10961 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
10963 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
10965 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
10967 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
10969 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
10970 * charset.c (Fdefine_charset_internal): Don't initialize
10971 charset.code_space[15]. The value was garbage, on hosts with
10972 32-bit int (Bug#8600).
10974 * lread.c (read_integer): Be more consistent with string-to-number.
10975 Use string_to_number to do the actual conversion; this avoids
10976 rounding errors and fixes some other screwups. Without this fix,
10977 for example, #x1fffffffffffffff was misread as -2305843009213693952.
10978 (digit_to_number): Move earlier, for benefit of read_integer.
10979 Return -1 if the digit is out of range for the base, -2 if it is
10980 not a digit in any supported base. (Bug#8602)
10982 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
10984 * dispnew.c (scrolling_window): Return 1 if we scrolled,
10985 to match comment at start of function. This also removes a
10986 GCC warning about overflow in a 32+64-bit port.
10988 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
10990 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
10991 Reported by Stefan Monnier in
10992 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
10993 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
10994 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
10996 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
10997 (EMACS_UINTPTR): Likewise, with uintptr_t.
10999 * lisp.h: Prefer 64-bit EMACS_INT if available.
11000 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
11001 on 32-bit hosts that have 64-bit int, so that they can access
11003 However, temporarily disable this change unless the temporary
11004 symbol WIDE_EMACS_INT is defined.
11006 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
11008 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
11009 This removes an assumption that EMACS_INT and long are the same
11010 width as pointers. The assumption is true for Emacs porting targets
11011 now, but we want to make other targets possible.
11012 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
11013 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
11014 In the rest of the code, change types of integers that hold casted
11015 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
11016 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
11017 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
11018 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
11019 No need to cast type when ORing.
11020 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
11021 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
11022 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
11023 assume EMACS_INT is the same width as char *.
11024 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
11025 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
11026 Remove no-longer-needed casts.
11027 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
11028 (xg_tool_bar_help_callback, xg_make_tool_item):
11029 Use EMACS_INTPTR to hold an integer
11030 that will be cast to void *; this can avoid a GCC warning
11031 if EMACS_INT is not the same width as void *.
11032 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
11033 * xdisp.c (display_echo_area_1, resize_mini_window_1):
11034 (current_message_1, set_message_1):
11035 Use a local to convert to proper width without a cast.
11036 * xmenu.c (dialog_selection_callback): Likewise.
11038 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
11039 Also, don't assume VALBITS / RAND_BITS is less than 5,
11040 and don't rely on undefined behavior when shifting a 1 left into
11042 * lisp.h (get_random): Change signature to match.
11044 * lread.c (hash_string): Use size_t, not int, for hash computation.
11045 Normally we prefer signed values; but hashing is special, because
11046 it's better to use unsigned division on hash table sizes so that
11047 the remainder is nonnegative. Also, size_t is the natural width
11048 for hashing into memory. The previous code used 'int', which doesn't
11049 retain enough info to hash well into very large tables.
11050 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
11052 * dbusbind.c: Don't possibly lose pointer info when converting.
11053 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
11054 Use XPNTR rather than XHASH, so that the high-order bits of
11055 the pointer aren't lost when converting through void *.
11057 * eval.c (Fautoload): Don't double-shift a pointer.
11059 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
11061 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
11063 * gnutls.c (DEF_GNUTLS_FN):
11064 * image.c (DEF_IMGLIB_FN): Make function pointers static.
11066 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
11068 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
11071 2011-05-05 Eli Zaretskii <eliz@gnu.org>
11073 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
11074 New version that can reserve upto 2GB of heap space.
11076 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
11078 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
11080 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
11082 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
11083 `gnutls_certificate_set_x509_key_file'.
11085 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
11087 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
11088 Update dependencies.
11090 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
11092 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
11093 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
11094 Remove unused parameter `fildes'.
11095 * process.c (read_process_output, send_process): Don't pass it.
11097 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
11099 Fix previous change: the library cache is defined in w32.c.
11100 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
11101 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
11103 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
11105 Implement dynamic loading of GnuTLS on Windows.
11107 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
11108 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
11109 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
11112 * gnutls.c (Qgnutls_dll): Define.
11113 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
11114 (gnutls_*): Declare function pointers.
11115 (init_gnutls_functions): New function to initialize function pointers.

11118 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
11119 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
11120 (emacs_gnutls_write, emacs_gnutls_read)
11121 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
11122 (Fgnutls_available_p): New function.
11123 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
11124 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
11125 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
11127 * image.c: Include w32.h.
11128 (Vimage_type_cache): Delete.
11129 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
11130 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
11131 (w32_delayed_load): Move to w32.c.
11133 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
11135 * w32.c (QCloaded_from, Vlibrary_cache): Define.
11136 (w32_delayed_load): Move from image.c. When loading a library, record
11137 its filename in the :loaded-from property of the library id.
11138 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
11139 Initialize and staticpro them.
11140 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
11142 * process.c: Include lisp.h before w32.h, not after.
11143 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
11144 instead of gnutls_record_check_pending.
11146 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
11148 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
11150 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
11151 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
11154 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
11156 * xterm.c (x_set_frame_alpha): Do not set property on anything
11157 else than FRAME_X_OUTER_WINDOW (Bug#8608).
11159 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
11161 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
11163 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
11165 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
11166 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

11175 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
11177 * callproc.c: Indentation fixup.
11179 * sysdep.c (wait_for_termination_1): Make static.
11180 (wait_for_termination, interruptible_wait_for_termination):
11181 Move after wait_for_termination_1.
11183 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
11185 * sysdep.c (interruptible_wait_for_termination): New function
11186 which is like wait_for_termination, but allows keyboard
11189 * callproc.c (Fcall_process): Add (:file "file") as an option for
11191 (Fcall_process_region): Ditto.
11193 2011-04-30 Eli Zaretskii <eliz@gnu.org>
11195 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
11196 rather than `XVECTOR (FOO)->size'.
11198 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
11199 inttypes.h, as a gnulib replacement is used if it not available in
11202 2011-04-21 Eli Zaretskii <eliz@gnu.org>
11204 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
11205 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
11206 of MOST_POSITIVE_FIXNUM. (Bug#8528)
11208 * coding.c (coding_alloc_by_realloc): Error out if destination
11209 will grow beyond MOST_POSITIVE_FIXNUM.
11210 (decode_coding_emacs_mule): Abort if there isn't enough place in
11211 charbuf for the composition carryover bytes. Reserve an extra
11212 space for up to 2 characters produced in a loop.
11213 (decode_coding_iso_2022): Abort if there isn't enough place in
11214 charbuf for the composition carryover bytes.
11216 2011-04-21 Eli Zaretskii <eliz@gnu.org>
11218 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
11219 aborting when %lld or %lll format is passed.
11220 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
11221 %llo or %llx format is passed. (Bug#8545)
11223 * window.c (window_scroll_line_based): Use a marker instead of
11224 simple variables to record original value of point. (Bug#7952)
11226 * doprnt.c (doprnt): Fix the case where a multibyte sequence
11227 produced by %s or %c overflows available buffer space. (Bug#8545)
11229 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
11231 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
11232 (SIZE_MAX): Move defn after all includes, as they might #define it.
11234 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
11236 * w32.c (init_environment): Warn about defaulting HOME to C:\.
11238 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
11240 * keyboard.c (Qdelayed_warnings_hook): Define.
11241 (command_loop_1): Run `delayed-warnings-hook'
11242 if Vdelayed_warnings_list is non-nil.
11243 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
11244 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
11246 2011-04-28 Eli Zaretskii <eliz@gnu.org>
11248 * doprnt.c (doprnt): Don't return value smaller than the buffer
11249 size if the message was truncated. (Bug#8545).
11251 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
11253 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
11254 (Fx_window_property): #if-0 the whole functions, not just the bodies.
11256 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
11258 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
11260 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
11262 * makefile.w32-in: Update dependencies.
11264 2011-04-27 Eli Zaretskii <eliz@gnu.org>
11266 Improve `doprnt' and its usage. (Bug#8545)
11267 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
11268 `format_end'. Remove support for %l as a conversion specifier.
11269 Don't use xrealloc. Improve diagnostics when the %l size modifier
11270 is used. Update the commentary.
11272 * eval.c (verror): Simplify calculation of size_t.
11274 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
11277 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
11279 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
11282 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
11284 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
11285 This makes this file independent of the recent pseudovector change.
11287 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
11289 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
11291 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
11292 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
11293 Remove unused local.
11294 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
11296 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
11297 GCC 4.6.0 optimizes based on type-based alias analysis.
11298 For example, if b is of type struct buffer * and v of type struct
11299 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
11300 != &v->size, and therefore "v->size = 1; b->size = 2; return
11301 v->size;" must therefore return 1. This assumption is incorrect
11302 for Emacs, since it type-puns struct Lisp_Vector * with many other
11303 types. To fix this problem, this patch adds a new type struct
11304 vectorlike_header that documents the constraints on layout of vectors
11305 and pseudovectors, and helps optimizing compilers not get fooled
11306 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
11307 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
11308 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
11310 (XSETPVECTYPE): Rewrite in terms of new macro.
11311 (XSETPVECTYPESIZE): New macro, specifying both type and size.
11312 This is a bit clearer, and further avoids the possibility of
11313 undesirable aliasing.
11314 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
11315 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
11316 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
11317 since Lisp_Subr is a special case (no "next" field).
11318 (ASIZE): Now uses header.size rather than size.
11319 All previous uses of XVECTOR (foo)->size replaced to use this macro,
11320 to avoid the hassle of writing XVECTOR (foo)->header.size.
11321 (struct vectorlike_header): New type.
11322 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
11323 object, to help avoid aliasing.
11324 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
11325 (SUBRP): Likewise, since Lisp_Subr is a special case.
11326 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
11327 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
11328 (struct Lisp_Hash_Table): Combine first two members into a single
11329 struct vectorlike_header member. All uses of "size" and "next" members
11330 changed to be "header.size" and "header.next".
11331 * buffer.h (struct buffer): Likewise.
11332 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
11333 * frame.h (struct frame): Likewise.
11334 * process.h (struct Lisp_Process): Likewise.
11335 * termhooks.h (struct terminal): Likewise.
11336 * window.c (struct save_window_data, struct saved_window): Likewise.
11337 * window.h (struct window): Likewise.
11338 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
11339 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
11340 * buffer.c (init_buffer_once): Likewise.
11341 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
11343 * process.c (Fformat_network_address): Use local var for size,
11346 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
11348 Make the Lisp reader and string-to-float more consistent (Bug#8525)
11349 * data.c (atof): Remove decl; no longer used or needed.
11350 (digit_to_number): Move to lread.c.
11351 (Fstring_to_number): Use new string_to_number function, to be
11352 consistent with how the Lisp reader treats infinities and NaNs.
11353 Do not assume that floating-point numbers represent EMACS_INT
11354 without losing information; this is not true on most 64-bit hosts.
11355 Avoid double-rounding errors, by insisting on integers when
11356 parsing non-base-10 numbers, as the documentation specifies.
11357 * lisp.h (string_to_number): New decl, replacing ...
11358 (isfloat_string): Remove.
11359 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
11360 (read1): Do not accept +. and -. as integers; this
11361 appears to have been a coding error. Similarly, do not accept
11362 strings like +-1e0 as floating point numbers. Do not report
11363 overflow for integer overflows unless the base is not 10 which
11364 means we have no simple and reliable way to continue.
11365 Break out the floating-point parsing into a new
11366 function string_to_number, so that Fstring_to_number parses
11367 floating point numbers consistently with the Lisp reader.
11368 (digit_to_number): Move here from data.c. Make it static inline.
11369 (E_CHAR, EXP_INT): Remove, replacing with ...
11370 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
11371 (string_to_number): New function, replacing isfloat_string.
11372 This function checks for valid syntax and produces the resulting
11373 Lisp float number too. Rework it so that string-to-number
11374 no longer mishandles examples like "1.0e+". Use strtoumax,
11375 so that overflow for non-base-10 numbers is reported only when
11376 there's no portable and simple way to convert to floating point.
11378 * textprop.c (set_text_properties_1): Rewrite for clarity,
11379 and to avoid GCC warning about integer overflow.
11381 * intervals.h (struct interval): Use EMACS_INT for members
11382 where EMACS_UINT might cause problems. See
11383 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
11384 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
11385 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
11387 (offset_intervals): Tell GCC not to worry about length overflow
11388 when negating a negative length.
11390 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
11391 (overrun_check_free): Likewise.
11393 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
11394 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
11397 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
11398 (gnutls_make_error): Rename local to avoid shadowing.
11399 (gnutls_emacs_global_deinit): ifdef out; not used.
11400 (Fgnutls_boot): Use const for pointer to readonly storage.
11401 Comment out unused local. Fix pointer signedness problems.
11403 * lread.c (openp): Don't stuff size_t into an 'int'.
11404 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
11405 about possible signed overflow.
11407 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
11408 (GDK_KEY_g): Don't define if already defined.
11409 (xg_prepare_tooltip): Avoid pointer signedness problem.
11410 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
11412 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
11413 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
11415 * xfns.c (Fx_window_property): Simplify a bit,
11416 to make a bit faster and to avoid GCC 4.6.0 warning.
11417 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
11419 * fns.c (internal_equal): Don't assume size_t fits in int.
11421 * alloc.c (compact_small_strings): Tighten assertion a little.
11423 Replace pEd with more-general pI, and fix some printf arg casts.
11424 * lisp.h (pI): New macro, generalizing old pEd macro to other
11425 conversion specifiers. For example, use "...%"pI"d..." rather
11426 than "...%"pEd"...".
11427 (pEd): Remove. All uses replaced with similar uses of pI.
11428 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
11429 * alloc.c (check_pure_size): Don't overflow by converting size to int.
11430 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
11431 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
11432 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
11433 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
11434 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
11436 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
11437 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
11438 * print.c (safe_debug_print, print_object): Likewise.
11439 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
11441 Use pI instead of if-then-else-abort. Use %p to avoid casts,
11442 avoiding the 0 flag, which is not portable.
11443 * process.c (Fmake_network_process): Use pI to avoid cast.
11444 * region-cache.c (pp_cache): Likewise.
11445 * xdisp.c (decode_mode_spec): Likewise.
11446 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
11447 behavior on 64-bit hosts with printf arg.
11448 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
11449 (x_stop_queuing_selection_requests): Likewise.
11450 (x_get_window_property): Don't truncate byte count to an 'int'
11453 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
11454 here, since it parses constructs like leading '-' and spaces,
11455 which are not wanted; and it overflows with large numbers.
11456 Instead, simply match F[0-9]+, which is what is wanted anyway.
11458 * alloc.c: Remove unportable assumptions about struct layout.
11459 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
11460 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
11461 (allocate_vectorlike, make_pure_vector): Use the new macros,
11462 plus offsetof, to remove unportable assumptions about struct layout.
11463 These assumptions hold on all porting targets that I know of, but
11464 they are not guaranteed, they're easy to remove, and removing them
11465 makes further changes easier.
11467 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
11468 This doesn't fix a bug but makes the code clearer.
11469 (string_overrun_cookie): Now const. Use initializers that
11470 don't formally overflow signed char, to avoid warnings.
11471 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
11472 can cause Emacs to crash when string overrun checking is enabled.
11473 (allocate_buffer): Don't assume sizeof (struct buffer) is a
11474 multiple of sizeof (EMACS_INT); it need not be, if
11475 alignof(EMACS_INT) < sizeof (EMACS_INT).
11476 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
11478 2011-04-26 Juanma Barranquero <lekktu@gmail.com>

11505 2011-04-25 Eli Zaretskii <eliz@gnu.org>
11507 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
11508 "cast to pointer from integer of different size".
11510 Improve doprnt and its use in verror. (Bug#8545)
11511 * doprnt.c (doprnt): Document the set of format control sequences
11512 supported by the function. Use SAFE_ALLOCA instead of always
11515 * eval.c (verror): Don't limit the buffer size at size_max-1, that
11516 is one byte too soon. Don't use xrealloc; instead xfree and
11519 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
11521 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the

11525 gnutls_global_initialized. Added internals for the
11526 :verify-hostname-error, :verify-error, and :verify-flags
11527 parameters of `gnutls-boot' and documented those parameters in the
11528 docstring. Start callback support.
11529 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
11530 unless a fatal error occurred. Call gnutls_alert_send_appropriate

11606 Many local variables are now size_t instead of int or unsigned.
11607 Improve overflow protection. Support `l' modifier for integer
11608 conversions. Support %l conversion. Don't assume an EMACS_INT
11609 argument for integer conversions and for %c.

11628 * callint.c (Fcall_interactively): When displaying error message
11629 about invalid control letter, pass the character's codepoint, not

11631 in octal and display also its hex code.
11633 * character.c (char_string): Use %x to display the (unsigned)
11634 codepoint of an invalid character, to avoid displaying a bogus
11637 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
11638 `error', not SYMBOL_NAME itself.

11716 * dispextern.h (struct redisplay_interface): Rename param
11717 to avoid shadowing.
11718 * termhooks.h (struct terminal): Likewise.

11835 * nsfont.m: Fixed bugs in ns_get_family and
11836 ns_descriptor_to_entity that were caused by using free to
11837 deallocate memory blocks that were allocated by xmalloc (via
11838 xstrdup). This caused Emacs to crash when compiled with
11839 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
11840 --enable-checking=xmallocoverrun). xfree is now used to
11841 deallocate these memory blocks.

12255 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
12256 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
12257 Remove decls, since these functions are now static.
12258 (Funintern, Fget_internal_run_time): New decls, since these functions
12259 were already external.
12261 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:

12269 Mark functions with DEFUE instead of DEFUN,
12270 if they are used in other modules.
12271 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
12272 decls for now-static functions.
12273 * buffer.h (Fdelete_overlay): Remove decl.

12309 2011-04-13 Eli Zaretskii <eliz@gnu.org>
12311 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
12312 when at ZV. (Bug#8487)
12314 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
12316 * charset.c (Fclear_charset_maps): Use xfree instead of free.

12324 * alloc.c (overrun_check_malloc, overrun_check_realloc)
12325 (overrun_check_free): Protoize.
12327 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
12329 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
12330 since callers should never pass a negative size.
12331 Change the signature to match that of plain 'read' and 'write'; see
12332 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
12333 * lisp.h: Update prototypes of emacs_write and emacs_read.
12335 2011-04-11 Eli Zaretskii <eliz@gnu.org>
12337 * xdisp.c (redisplay_window): Don't try to determine the character
12338 position of the scroll margin if the window start point w->startp
12339 is outside the buffer's accessible region. (Bug#8468)
12341 2011-04-10 Eli Zaretskii <eliz@gnu.org>
12343 Fix write-region and its subroutines for buffers > 2GB.
12344 * fileio.c (a_write, e_write): Modify declaration of arguments and
12345 local variables to support buffers larger than 2GB.
12346 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
12348 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
12349 argument, local variables, and return value.
12351 * lisp.h: Update prototypes of emacs_write and emacs_read.
12353 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
12355 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
12357 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
12359 Fix more problems found by GCC 4.6.0's static checks.
12361 * xdisp.c (vmessage): Use a better test for character truncation.
12363 * charset.c (load_charset_map): <, not <=, for optimization,
12364 and to avoid potential problems with integer overflow.
12365 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
12366 * casetab.c (set_identity, shuffle): Likewise.
12367 * editfns.c (Fformat): Likewise.
12368 * syntax.c (skip_chars): Likewise.
12370 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
12371 This also lets GCC 4.6.0 generate slightly better loop code.
12373 * callint.c (Fcall_interactively): <, not <=, for optimization.
12374 (Fcall_interactively): Count the number of arguments produced,
12375 not the number of arguments given. This is simpler and lets GCC
12376 4.6.0 generate slightly better code.
12378 * ftfont.c: Distingish more carefully between FcChar8 and char.
12379 The previous code passed unsigned char * to a functions like
12380 strlen and xstrcasecmp that expect char *, which does not
12381 conform to the C standard.
12382 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
12383 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
12384 char * when the C standard requires it.
12386 * keyboard.c (read_char): Remove unused var.
12388 * eval.c: Port to Windows vsnprintf (Bug#8435).
12389 Include <limits.h>.
12390 (SIZE_MAX): Define if the headers do not.
12391 (verror): Do not give up if vsnprintf returns a negative count.
12392 Instead, grow the buffer. This ports to Windows vsnprintf, which
12393 does not conform to C99. Problem reported by Eli Zaretskii.
12394 Also, simplify the allocation scheme, by avoiding the need for
12395 calling realloc, and removing the ALLOCATED variable.
12397 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
12399 Remove invocations of doprnt, as Emacs now uses vsnprintf.
12400 But keep the doprint source code for now, as we might revamp it
12401 and use it again (Bug#8435).
12402 * lisp.h (doprnt): Remove.
12403 * Makefile.in (base_obj): Remove doprnt.o.
12404 * deps.mk (doprnt.o): Remove.
12406 error: Print 32- and 64-bit integers portably (Bug#8435).
12407 Without this change, on typical 64-bit hosts error ("...%d...", N)
12408 was used to print both 32- and 64-bit integers N, which relied on
12409 undefined behavior.
12410 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
12411 * lisp.h (error, verror): Mark as printf-like functions.
12412 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
12413 Report overflow in size calculations when allocating printf buffer.
12414 Do not truncate output string at its first null byte.
12415 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
12416 Truncate the output at a character boundary, since vsnprintf does not
12418 * charset.c (check_iso_charset_parameter): Convert internal
12419 character to string before calling 'error', since %c now has the
12421 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
12422 overflow when computing char to be passed to 'error'. Do not
12423 pass Lisp_Object to 'error'; pass the integer instead.
12424 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
12425 formatted with plain %d.
12427 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
12429 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
12431 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
12433 * xterm.c (x_catch_errors): Remove duplicate declaration.
12435 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
12437 * xdisp.c, lisp.h (message_nolog): Remove; unused.
12439 2011-04-10 Jim Meyering <meyering@redhat.com>
12441 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
12442 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
12443 return ssize_t not "int", and use size_t as the buffer length.
12444 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
12445 * gnutls.h: Update declarations.
12446 * process.c (read_process_output): Use ssize_t, to match.
12447 (send_process): Likewise.
12449 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
12451 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
12453 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
12455 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
12456 Use unsigned char, to match FcChar8 type definition.
12458 * xterm.c (handle_one_xevent):
12459 * xmenu.c (create_and_show_popup_menu):
12460 * xselect.c (x_decline_selection_request)
12461 (x_reply_selection_request): Avoid type-punned deref of X events.
12463 2011-04-09 Eli Zaretskii <eliz@gnu.org>
12465 Fix some uses of `int' instead of EMACS_INT.
12466 * search.c (string_match_1, fast_string_match)
12467 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
12468 (scan_buffer, find_next_newline_no_quit)
12469 (find_before_next_newline, search_command, Freplace_match)
12470 (Fmatch_data): Make some `int' variables be EMACS_INT.
12472 * xdisp.c (display_count_lines): 3rd argument and return value now
12473 EMACS_INT. All callers changed.
12474 (pint2hrstr): Last argument is now EMACS_INT.
12476 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
12477 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)

12489 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
12490 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
12492 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
12493 (encode_invocation_designation): Last argument P_NCHARS is now
12495 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
12496 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
12498 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
12501 * ccl.c (Fccl_execute_on_string): Declare some variables
12504 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
12506 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
12508 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
12510 * process.c (Fformat_network_address): Doc fix.
12512 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
12514 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
12516 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
12518 * keyboard.c (read_char): Call Lisp function help-form-show,
12519 instead of using internal_with_output_to_temp_buffer.
12520 (Qhelp_form_show): New var.
12521 (syms_of_keyboard): Use DEFSYM macro.
12523 * print.c (internal_with_output_to_temp_buffer): Function deleted.
12525 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
12527 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
12529 * process.c (Flist_processes): Remove to Lisp.

12536 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
12538 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
12540 Fix more problems found by GCC 4.6.0's static checks.

12544 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
12546 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
12548 * xdisp.c (vmessage): Mark as a printf-like function.
12550 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
12552 * sound.c (sound_warning): Don't crash if arg contains a printf format.

12557 to system-supplied API.
12559 * eval.c (Fsignal): Remove excess argument to 'fatal'.
12561 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
12562 This avoids several warnings with gcc -Wstrict-overflow.
12563 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
12564 directly, rather than having caller test rule sign. This avoids
12565 some unnecessary tests.
12566 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
12567 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
12568 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
12570 * xfont.c (xfont_text_extents): Remove var that was set but not used.
12571 (xfont_open): Avoid unnecessary tests.
12573 * composite.c (composition_gstring_put_cache): Use unsigned integer.
12575 * composite.h, composite.c (composition_gstring_put_cache):
12576 Use EMACS_INT, not int, for length.

12582 by using the new macro.
12584 * textprop.c (set_text_properties_1): Change while to do-while,
12585 since the condition is always true at first.
12587 * intervals.c (graft_intervals_into_buffer): Mark var as used.
12588 (interval_deletion_adjustment): Return unsigned value.
12591 * process.c (list_processes_1, create_pty, read_process_output):

12603 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
12604 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
12605 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
12607 * print.c (print_error_message): Avoid int overflow.
12609 * font.c (font_list_entities): Redo for clarity,
12610 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
12612 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
12613 (font_score): Avoid potential overflow in diff calculation.
12615 * fns.c (substring_both): Remove var that is set but not used.
12616 (sxhash): Redo loop for clarity and to avoid wraparound warning.
12618 * eval.c (funcall_lambda): Rename local to avoid shadowing.
12620 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
12621 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
12622 can always succeed if overflow has undefined behavior.
12624 * search.c (boyer_moore, wordify): Remove vars set but not used.
12625 (wordify): Omit three unnecessary tests.
12627 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
12628 All callers changed. This avoids the need for an unused var.
12630 * casefiddle.c (casify_region): Remove var that is set but not used.
12632 * dired.c (file_name_completion): Remove var that is set but not used.
12634 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
12636 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
12637 (Finsert_file_contents): Remove unnecessary code checking fd.
12639 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
12640 Check for integer overflow on size calculations.
12642 * buffer.c (Fprevious_overlay_change): Remove var that is set
12645 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
12646 Remove vars that are set but not used.
12647 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
12648 (timer_check_2): Mark vars as initialized.
12650 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
12652 * image.c (lookup_image): Remove var that is set but not used.
12653 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
12655 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
12656 that are set but not used.
12658 * xfns.c (make_invisible_cursor): Don't return garbage
12659 if XCreateBitmapFromData fails (Bug#8410).
12661 * xselect.c (x_get_local_selection, x_handle_property_notify):
12662 Remove vars that are set but not used.
12664 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
12665 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
12667 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
12668 Remove var that is set but not used.

12670 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
12671 Check for overflow.
12673 * xfaces.c (realize_named_face): Remove vars that are set but not used.
12674 (map_tty_color) [!defined MSDOS]: Likewise.
12676 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
12678 * coding.c: Remove vars that are set but not used.
12679 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
12680 All callers changed.
12681 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
12682 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
12683 (decode_coding_charset): Remove vars that are set but not used.
12685 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
12686 that is set but not used.
12688 * print.c (print_object): Remove var that is set but not used.
12690 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
12691 The gnulib version avoids calling malloc in the usual case,
12692 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
12693 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
12694 * filelock.c (current_lock_owner): Likewise.
12695 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
12696 * sysdep.c: Include allocator.h, careadlinkat.h.
12697 (emacs_no_realloc_allocator): New static constant.

12727 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
12728 (ns_get_family): Likewise.
12730 2011-04-02 Juanma Barranquero <lekktu@gmail.com>

12736 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
12739 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
12741 Add lexical binding.

12752 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
12754 (syms_of_lread): Declare `lexical-binding'.
12756 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
12758 * keyboard.c (eval_dyn): New fun.
12759 (menu_item_eval_property): Use it.
12761 * image.c (parse_image_spec): Use Ffunctionp.
12763 * fns.c (concat, mapcar1): Accept byte-code-functions.
12765 * eval.c (Fsetq): Handle lexical vars.
12766 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
12767 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
12768 (FletX, Flet): Obey lexical binding.
12769 (Fcommandp): Handle closures.
12770 (Feval): New `lexical' arg.
12771 (eval_sub): New function extracted from Feval. Use it almost
12772 everywhere where Feval was used. Look up vars in lexical env.
12774 (Ffunctionp): Move from subr.el.
12775 (Ffuncall): Handle closures.
12776 (apply_lambda): Remove `eval_flags'.
12777 (funcall_lambda): Handle closures and new byte-code-functions.
12778 (Fspecial_variable_p): New function.
12779 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
12780 but without exporting it to Lisp.
12782 * doc.c (Fdocumentation, store_function_docstring):
12783 * data.c (Finteractive_form): Handle closures.
12785 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
12788 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
12790 (exec_byte_code): New function extracted from Fbyte_code to handle new
12791 calling convention for byte-code-functions. Add new byte-codes.
12793 * buffer.c (defvar_per_buffer): Set new `declared_special' field.

12799 * xdisp.c (redisplay_internal): Fix prototype.
12801 2011-03-31 Eli Zaretskii <eliz@gnu.org>
12803 * xdisp.c (SCROLL_LIMIT): New macro.
12804 (try_scrolling): Use it when setting scroll_limit.
12805 Limit scrolling to 100 screen lines.
12806 (redisplay_window): Even when falling back on "recentering",
12807 position point in the window according to scroll-conservatively,
12808 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
12810 (try_scrolling): When point is above the window, allow searching
12811 as far as scroll_max, or one screenful, to compute vertical
12812 distance from PT to the scroll margin position. This prevents
12813 try_scrolling from unnecessarily failing when
12814 scroll-conservatively is set to a value slightly larger than the
12815 window height. Clean up the case of PT below the margin at bottom
12816 of window: scroll_max can no longer be INT_MAX. When aggressive
12817 scrolling is in use, don't let point enter the opposite scroll
12818 margin as result of the scroll.
12819 (syms_of_xdisp) <scroll-conservatively>: Document the
12820 threshold of 100 lines for never-recentering scrolling.
12822 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
12824 * dispextern.h (move_it_by_lines):

12830 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
12832 * indent.c (Fvertical_motion):
12833 * window.c (window_scroll_pixel_based, Frecenter):
12834 Don't pass `need_y_p' to `move_it_by_lines'.
12836 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
12838 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
12839 steal a few bits to be more compact.
12840 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
12841 Remove unneeded casts.
12843 * bytecode.c (Fbyte_code): CAR and CDR can GC.
12845 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
12847 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
12848 binding" message (bug#7967).
12850 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
12852 Fix more problems found by GCC 4.6.0's static checks.
12854 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
12855 Remove unused local var.
12857 * editfns.c (Fmessage_box): Remove unused local var.
12859 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
12860 (note_mode_line_or_margin_highlight, note_mouse_highlight):
12861 Omit unused local vars.
12862 * window.c (shrink_windows): Omit unused local var.
12863 * menu.c (digest_single_submenu): Omit unused local var.
12864 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
12865 Omit unused local var.
12867 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
12868 Don't assume string length fits in int.
12869 (keyremap_step, read_key_sequence): Use size_t for sizes.
12870 (read_key_sequence): Don't check last_real_key_start redundantly.
12872 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
12873 instead of alloca (Bug#8344).
12875 * eval.c (Fbacktrace): Don't assume nargs fits in int.
12876 (Fbacktrace_frame): Don't assume nframes fits in int.
12878 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

12885 * cm.c (calccost): Turn while-do into do-while, for clarity.
12887 * keyboard.c (syms_of_keyboard): Use the same style as later
12888 in this function when indexing through an array. This also
12889 works around GCC bug 48267.
12891 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
12893 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
12895 * chartab.c (sub_char_table_ref_and_range): Redo for slight
12896 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
12898 * keyboard.c, keyboard.h (num_input_events): Now size_t.
12899 This avoids undefined behavior on integer overflow, and is a bit
12900 more convenient anyway since it is compared to a size_t variable.
12902 Variadic C functions now count arguments with size_t, not int.
12903 This avoids an unnecessary limitation on 64-bit machines, which
12904 caused (substring ...) to crash on large vectors (Bug#8344).

12914 * fns.c (concat): Likewise.
12915 * frame.c (x_set_frame_parameters): Likewise.
12916 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
12917 0 if not found, not -1. All callers changed.
12919 * alloc.c (garbage_collect): Don't assume stack size fits in int.
12920 (stack_copy_size): Now size_t, not int.
12921 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
12923 2011-03-28 Juanma Barranquero <lekktu@gmail.com>

12942 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
12943 don't set the hook to nil, but remove the offending function instead.
12944 (Qcommand_hook_internal): Remove, unused.
12945 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
12946 Vcommand_hook_internal.
12948 * eval.c (enum run_hooks_condition): Remove.
12949 (funcall_nil, funcall_not): New functions.
12950 (run_hook_with_args): Call each function through a `funcall' argument.

13136 * coding.c (encode_coding_raw_text): Avoid unnecessary test
13137 the first time through the loop, since we know p0 < p1 then.
13138 This also avoids a gcc -Wstrict-overflow warning.
13140 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
13141 leading to a memory leak, possible in functions like
13142 load_charset_map_from_file that can allocate an unbounded number
13143 of objects (Bug#8318).
13145 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
13146 that could (at least in theory) be that large.
13148 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
13149 This is less likely to overflow, and avoids undefined behavior if
13150 overflow does occur. All callers changed. Use strtoul to scan
13151 for the unsigned long integer.
13152 (pint2hrstr): Simplify and tune code slightly.
13153 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
13155 * scroll.c (do_scrolling): Work around GCC bug 48228.
13156 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
13158 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
13159 This also avoids a warning with gcc -Wstrict-overflow.
13160 (validate_x_resource_name): Simplify count usage.
13161 This also avoids a warning with gcc -Wstrict-overflow.
13163 * fileio.c (Fcopy_file): Report error if fchown or fchmod
13166 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
13168 * process.c (Fmake_network_process): Use socklen_t, not int,
13169 where POSIX says socklen_t is required in portable programs.
13170 This fixes a porting bug on hosts like 64-bit HP-UX, where
13171 socklen_t is wider than int (Bug#8277).
13172 (Fmake_network_process, server_accept_connection):
13173 (wait_reading_process_output, read_process_output):
13176 * process.c: Rename or move locals to avoid shadowing.

13178 (read_process_output_error_handler, exec_sentinel_error_handler):
13179 Rename or move locals.
13180 (Fmake_network_process): Define label "retry_connect" only if needed.
13181 (Fnetwork_interface_info): Fix pointer signedness.
13182 (process_send_signal): Add cast to avoid pointer signedness problem.
13183 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
13184 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
13186 Make tparam.h and terminfo.c consistent.
13187 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
13188 Include tparam.h instead, since it declares them.
13189 * cm.h (PC): Remove extern decl; tparam.h now does this.
13190 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
13191 * terminfo.c: Include tparam.h, to check interfaces.
13192 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
13193 (tparam): Adjust signature to match interface in tparam.h;
13194 this removes some undefined behavior. Check that outstring and len
13195 are zero, which they always are with Emacs.
13196 * tparam.h (PC, BC, UP): New extern decls.
13198 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
13199 (xftfont_open): Rename locals to avoid shadowing.
13201 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.

13211 * xml.c (make_dom): Now static.
13213 * composite.c (composition_compute_stop_pos): Rename local to
13215 (composition_reseat_it): Remove unused locals.
13216 (find_automatic_composition, composition_adjust_point): Likewise.
13217 (composition_update_it): Mark var as initialized.
13218 (find_automatic_composition): Mark vars as initialized,
13219 with a FIXME (Bug#8290).

13223 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
13224 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
13225 (BUF_DEC_POS): Be more systematic about renaming local temporaries
13226 to avoid shadowing.
13228 * textprop.c (property_change_between_p): Remove; unused.
13230 * intervals.c (interval_start_pos): Now static.
13232 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

13235 Rename locals to avoid shadowing.
13237 * sound.c (wav_play, au_play, Fplay_sound_internal):
13238 Fix pointer signedness.
13239 (alsa_choose_format): Remove unused local var.
13240 (wav_play): Initialize a variable to 0, to prevent undefined
13241 behavior (Bug#8278).
13243 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
13245 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
13247 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
13248 clobbering (Bug#8298).
13249 * sysdep.c (sys_subshell): Likewise.
13250 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
13252 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
13253 This should get cleaned up, so that child_setup has the
13254 same signature on all platforms.
13256 * callproc.c (call_process_cleanup): Now static.
13257 (relocate_fd): Rename locals to avoid shadowing.
13259 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
13261 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
13262 not to be necessary, and produces flickering.
13264 2011-03-20 Glenn Morris <rgm@gnu.org>
13266 * config.in: Remove file.
13268 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
13270 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
13271 are now in src/globals.h.
13272 (syms_of_minibuf): Remove spurious & from previous change.
13274 2011-03-20 Leo Liu <sdl.web@gmail.com>
13276 * minibuf.c (completing-read-function): New variable.
13277 (completing-read-default): Rename from completing-read.
13278 (completing-read): Call completing-read-function.
13280 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
13282 * xfaces.c (Fx_load_color_file):
13283 Read color file from absolute filename (bug#8250).
13285 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
13287 * makefile.w32-in: Update dependencies.
13289 2011-03-17 Eli Zaretskii <eliz@gnu.org>
13291 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.

13298 (sigchld_handler): Now static.
13300 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.

13311 (CONSTANTLIM): Remove; unused.
13312 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
13313 Define only if needed.
13315 * unexelf.c (unexec): Name an expression,
13316 to avoid gcc -Wbad-function-cast warning.
13317 Use a different way to cause a compilation error if anyone uses
13318 n rather than nn, a way that does not involve shadowing.
13319 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
13321 * deps.mk (unexalpha.o): Remove; unused.
13323 New file unexec.h, the (simple) interface for unexec (Bug#8267).
13324 * unexec.h: New file.
13325 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
13326 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
13327 Depend on unexec.h.
13328 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
13329 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
13330 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.

13378 * callint.c (quotify_arg, quotify_args): Now static.
13379 (Fcall_interactively): Rename locals to avoid shadowing.
13380 Use const pointer when appropriate.
13382 * lisp.h (get_system_name, get_operating_system_release):

13386 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
13387 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
13388 some of which prompt warnings from gcc -Wbad-function-cast.
13389 (Fformat_time_string, Fencode_time, Finsert_char):
13390 (Ftranslate_region_internal, Fformat):
13391 Rename or remove local vars to avoid shadowing.

13394 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
13397 * lisp.h (eassert): Check that the argument compiles, even if

13416 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
13417 (GC_STRING_CHARS): Remove; not used.
13418 (Fmemory_limit): Cast sbrk's returned value to char *.
13420 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
13421 avoids undefined behavior in theory.
13423 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
13425 Use functions, not macros, for up- and down-casing (Bug#8254).
13426 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
13427 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
13428 to use the following functions instead of these macros.
13429 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
13430 EMACS_INT, since callers assume the returned value fits in int.
13431 (upcase1): Likewise, for UPCASE_TABLE.
13432 (uppercasep, lowercasep, upcase): New static inline functions.
13433 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

13442 which gcc can warn about.
13443 (regex_compile, re_match_2_internal): Mark locals as initialized.
13444 (RETALLOC_IF): Define only if needed.
13445 (WORDCHAR_P): Likewise. This one is never needed, but is used
13446 only in a comment talking about a compiler bug, so put inside
13447 the #if 0 of that comment.
13448 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
13449 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
13452 * search.c (boyer_moore): Rename locals to avoid shadowing.
13453 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):

13466 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
13467 Rename locals to avoid shadowing.
13468 (Fvertical_motion): Mark locals as initialized.
13470 * casefiddle.c (casify_object, casify_region): Now static.
13471 (casify_region): Mark local as initialized.
13473 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
13475 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
13476 New macros, so that the caller can use some names other than
13477 gcpro1, gcpro2, etc.
13478 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
13480 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
13481 argument, for consistency with GCPRO2_VAR, etc: it is now the
13482 prefix of the variable, not the variable itself. All uses
13484 * dired.c (directory_files_internal, file_name_completion):
13485 Rename locals to avoid shadowing.
13487 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
13488 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
13489 dired.c's scmp function, had undefined behavior.
13490 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
13491 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
13492 * buffer.h: ... to here, because these macros use current_buffer,
13493 and the new implementation with inline functions needs to have
13494 current_buffer in scope now, rather than later when the macros
13496 (downcase, upcase1): New static inline functions.
13497 (DOWNCASE, UPCASE1): Reimplement using these functions.
13498 This avoids undefined behavior in expressions like
13499 DOWNCASE (x) == DOWNCASE (y), which previously suffered
13500 from race conditions in accessing the global variables
13501 case_temp1 and case_temp2.
13502 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
13503 * lisp.h (case_temp1, case_temp2): Remove their decls.
13504 * character.h (ASCII_CHAR_P): Move from here ...
13505 * lisp.h: ... to here, so that the inline functions mentioned
13506 above can use them.
13508 * dired.c (directory_files_internal_unwind): Now static.
13510 * fileio.c (file_name_as_directory, directory_file_name):
13511 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
13513 (file_name_as_directory): Use const pointers when appropriate.
13514 (Fexpand_file_name): Likewise. In particular, newdir might
13515 point at constant storage, so make it a const pointer.
13516 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
13517 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
13519 (Fset_file_times, Finsert_file_contents, auto_save_error):
13520 Rename locals to avoid shadowing.

13524 to avoid shadowing.
13526 * marker.c (bytepos_to_charpos): Remove; unused.
13528 * lisp.h (verify_bytepos, count_markers): New decls,
13529 so that gcc does not warn that these functions aren't declared.
13531 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
13532 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
13533 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
13534 (copy_text): Remove unused local var.
13536 * filelock.c (within_one_second): Now static.
13537 (lock_file_1): Rename local to avoid shadowing.
13539 * buffer.c (fix_overlays_before): Mark locals as initialized.
13540 (fix_start_end_in_overlays): Likewise. This function should be
13541 simplified by using pointers-to-pointers, but that's a different
13543 (switch_to_buffer_1): Now static.
13544 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
13545 (report_overlay_modification): Rename locals to avoid shadowing.
13547 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
13548 Fix pointer signedness issue.
13549 (sys_subshell): Mark local as volatile if checking for lint,
13550 to suppress a gcc -Wclobbered warning that does not seem to be right.
13551 (MAXPATHLEN): Define only if needed.
13553 * process.c (serial_open, serial_configure): Move decls from here ...
13554 * systty.h: ... to here, so that they can be checked.
13556 * fns.c (get_random, seed_random): Move extern decls from here ...
13557 * lisp.h: ... to here, so that they can be checked.
13559 * sysdep.c (reset_io): Now static.
13560 (wait_for_termination_signal): Remove; unused.
13562 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

13565 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
13566 (DENSE_TABLE_SIZE): Remove; unused.
13567 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
13568 (describe_map_tree):
13569 Rename locals to avoid shadowing.
13571 * keyboard.c: Declare functions static if they are not used elsewhere.
13572 (echo_char, echo_dash, cmd_error, top_level_2):
13573 (poll_for_input, handle_async_input): Now static.
13574 (read_char, kbd_buffer_get_event, make_lispy_position):
13575 (make_lispy_event, make_lispy_movement, apply_modifiers):

13577 (parse_tool_bar_item, read_key_sequence, Fread_key_sequence):
13578 (Fread_key_sequence_vector): Rename locals to avoid shadowing.
13579 (read_key_sequence, read_char): Mark locals as initialized.
