26 * window.h (struct window): Replace hchild, vchild and buffer slots
27 with the only contents slot. This is possible because each valid
28 window may have either the child window (in vertical or horizontal
29 combination) or buffer to display (for the leaf window). Using that,
30 a lof of operations to traverse and/or change window hierarchies may
31 be simplified. New member horizontal is used to distinguish between
32 horizontal and vertical combinations of internal windows.

61 (sync_window_with_frame_matrix_rows): Enforce live window.
62 Use contents slot, not buffer, where appropriate.

71 * textprop.c (get_char_property_and_overlay): Add CHECK_LIVE_WINDOW
72 to avoid deleted windows. Use contents slot instead of buffer.
73 * buffer.c, dispextern.h, editfns.c, fileio.c, font.c, fringe.c:
74 * indent.c, insdel.c, keyboard.c, keymap.c, minibuf.c, msdos.c:
75 * nsfns.m, nsmenu.m, nsterm.m, print.c, w32fns.c, w32menu.c, xfaces.c:

257 'fullscreen' parameter. Always record previous width and height
258 of the frame, except when switching out of maximized modes, so
259 that they could be restored correctly, instead of resetting to the
260 default frame dimensions. Send SC_RESTORE command to the frame,
261 unless we are going to send SC_MAXIMIZE, to restore the frame
262 resize hints in the mouse pointer shown by the window manager.

393 Use getFilename and getDirectory.
394 (getFilename, getDirectory): New methods for EmacsSavePanel and
396 (ok:): In EmacsOpenPanel, if we can't choose directories, just return.

415 (produce_chars): Call insert_from_gap with the new arg 0.
416 (encode_coding): Likewise.
417 (decode_coding_gap): Control ASCII optimization by the variable

468 * w32term.c (w32_read_socket): If the Emacs frame is being
469 activated, call w32fullscreen_hook, to make sure the new frame
470 dimensions are in effect. (Bug#13937)
472 2013-03-13 Dmitry Antipov <dmantipov@yandex.ru>
474 * xdisp.c (init_iterator): Simplify because both character and byte
475 positions are either specified or -1. Add eassert. Adjust comment.

498 is simpler here. Include <sys/sysctl.h> if DARWIN_OS ||
499 __FreeBSD__, not if BSD_SYSTEM, since it's needed only for Darwin

643 to match other functions accepting character and byte positions.
645 (bidi_resolve_explicit_1, bidi_level_of_next_char): Adjust users.

726 * sysdep.c (list_system_processes)
727 [BSD_SYSTEM && !DARWIN_OS && !__FreeBSD__]:
728 Make it a stub in this case; otherwise the build might fail,
729 and this code hasn't been tested on such hosts anyway.
730 Problem reported by Nelson H. F. Beebe in
731 <http://lists.gnu.org/archive/html/emacs-devel/2013-03/msg00021.html>
732 and analyzed by Jérémie Courrèges-Anglas in

735 2013-03-06 Dmitry Antipov <dmantipov@yandex.ru>
737 * lisp.h (find_next_newline_no_quit): Rename to find_next_newline.

743 2013-03-05 Paul Eggert <eggert@cs.ucla.edu>
745 FILE's lock is now always .#FILE and may be a regular file (Bug#13807).
746 * filelock.c: Include <c-ctype.h>.
747 (MAX_LFINFO): New top-level constant.
748 (lock_info_type): Remove members pid, boot_time. Add members at,
749 dot, colon. Change user member to be the entire buffer, not a
750 pointer. This allows us to handle the case where a foreign
751 pid or boot time exceeds the local range. All uses changed.
752 (LINKS_MIGHT_NOT_WORK): New constant.
753 (FREE_LOCK_INFO): Remove, as the pieces no longer need freeing.
754 (defined_WINDOWSNT): Remove.
755 (MAKE_LOCK_NAME, file_in_lock_file_name):
756 Always use .#FILE (not .#-FILE) for the file lock,
757 even if it is a regular file.
758 (rename_lock_file): New function.
759 (create_lock_file): Use it.
760 (create_lock_file, read_lock_data):
761 Prefer a symbolic link for the lock file, falling back on a
762 regular file if symlinks don't work. Do not try to create
763 symlinks on MS-Windows, due to security hassles. Stick with
764 POSIXish functions (open, read, write, close, fchmod, readlink, symlink,
765 link, rename, unlink, mkstemp) when creating locks, as a GNUish
766 host may be using a Windowsish file system, and cannot use
767 MS-Windows-only system calls. Fall back on mktemp if mkstemp
768 doesn't work. Don't fail merely because of a symlink-contents
769 length limit in the current file system; fall back on regular
770 files. Increase the symlink contents length limit to 8 KiB, this
771 should be big enough for any real use and doesn't crunch the
773 (create_lock_file, lock_file_1, read_lock_data):
774 Simplify allocation of lock file buffers now that they fit in 8 KiB.
775 (lock_file_1): Return error number, not bool. All callers changed.
776 (ELOOP): New macro, if not already defined.
777 (read_lock_data): Return size of lock file contents, not Lisp object.
778 All callers changed. Handle a race condition if some other process
779 replaces a regular-file lock with a symlink lock or vice versa,
780 while we're trying to read the lock.
781 (current_lock_owner): Parse contents more carefully, to help avoid
782 confusing a regular-file lock with some other application's use
783 of the file. Check for lock file contents being too long, or
784 not parsing correctly.
785 (current_lock_owner, lock_file):
786 Allow foreign pid and boot times that exceed the local range.
787 (current_lock_owner, lock_if_free, lock_file):
788 Simplify allocation of lock file contents.
789 * w32.c (sys_rename_replace): New function, containing most of
790 the contents of the old sys_rename.
791 (sys_rename): Use it.
792 (fchmod): New dummy function.
793 * w32.h (sys_rename_replace, fchmod): New decls.
795 2013-03-05 Eli Zaretskii <eliz@gnu.org>
797 * bidi.c (bidi_resolve_explicit_1): Don't call CHAR_TO_BYTE or
798 bidi_count_bytes, as the callers now arrange for bidi_it->charpos
799 to be in sync with bidi_it->bytepos. Suggested by Dmitry Antipov
800 <dmantipov@yandex.ru>.
802 2013-03-05 Dmitry Antipov <dmantipov@yandex.ru>
804 * composite.c (get_composition_id, fill_gstring_header):
805 Use make_uninit_vector where appropriate.
806 * font.c (Ffont_get_glyphs, build_style_table): Likewise.
807 * xselect.c (clean_local_selection_data): Likewise.
809 2013-03-04 Paul Eggert <eggert@cs.ucla.edu>
811 Fix misuse of ImageMagick that caused core dump (Bug#13846).
812 * image.c (imagemagick_load_image): Calculate height and width
813 after flattening the image, not before.
815 2013-03-04 Dmitry Antipov <dmantipov@yandex.ru>
817 * font.c (Ffont_get_glyphs): Use convenient LGLYPH_NEW.
818 * ftfont.c (ftfont_shape_by_flt): Likewise.
819 * w32uniscribe.c (uniscribe_shape): Likewise.
821 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
823 The lock for FILE is now .#FILE or .#-FILE (Bug#13807).
824 The old approach, which fell back on DIR/.#FILE.0 through
825 DIR/.#FILE.9, had race conditions that could not be easily fixed.
826 If DIR/.#FILE is a non-symlink file, Emacs now does not create a
827 lock file for DIR/FILE; that is, DIR/FILE is no longer partly
828 protected by a lock if DIR/.#FILE is a non-symlink file ("partly"
829 because the locking mechanism was never reliable in that case).
830 This patch fixes this and other bugs discovered by a code
831 inspection that was prompted by
832 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00531.html>.
833 Also, this patch switches to .#-FILE (not .#FILE) on MS-Windows,
834 to avoid interoperability problems between the MS-Windows and
835 non-MS-Windows implementations. MS-Windows and non-MS-Windows
836 instances of Emacs now ignore each others' locks.
837 * filelock.c (defined_WINDOWSNT): New constant.
838 (MAKE_LOCK_NAME, fill_in_lock_file_name):
839 Don't create DIR/.#FILE.0 through DIR/.#FILE.9. Instead, create
840 DIR/.#FILE symlinks on non-MS-Windows hosts, and DIR/.#-FILE
841 regular files on MS-Windows hosts.
842 (MAKE_LOCK_NAME, unlock_file, Ffile_locked_p):
843 Use SAFE_ALLOCA to avoid problems with long file names.
844 (MAX_LFINFO): Now a local constant, not a global macro.
845 (IS_LOCK_FILE): Remove.
846 (lock_file_1): Don't inspect errno if symlink call succeeds;
848 (lock_file): Document that this function can return if lock
850 (lock_file): Don't access freed storage.
852 2013-03-02 Andreas Schwab <schwab@linux-m68k.org>

856 2013-03-02 Paul Eggert <eggert@cs.ucla.edu>
858 * textprop.c: Use bool for booleans.
859 (validate_interval_range, Fadd_text_properties)
860 (Fremove_text_properties): Prefer bool to int when either works.
862 2013-03-02 Eli Zaretskii <eliz@gnu.org>
864 * textprop.c (Fadd_text_properties, Fremove_text_properties):
865 If the interval tree changes as a side effect of calling
866 modify_region, re-do processing starting from the call to
867 validate_interval_range. (Bug#13743)
869 2013-02-28 Eli Zaretskii <eliz@gnu.org>
871 * w32.c (sys_open): Don't reset the flags for FD in fd_info[].
874 2013-02-27 Eli Zaretskii <eliz@gnu.org>
876 * filelock.c (create_lock_file) [WINDOWSNT]: Use _sopen with
877 _SH_DENYRW flag, instead of emacs_open, to deny any other process
878 access to the lock file until it is written and closed.
881 2013-02-27 Paul Eggert <eggert@cs.ucla.edu>
883 * callint.c (Qcall_interactively):
884 * macros.c (Qexecute_kbd_macro):

891 2013-02-26 Paul Eggert <eggert@cs.ucla.edu>
893 Minor textprop integer cleanup.
894 * intervals.h, textprop.c (add_text_properties_from_list):
895 Return void, not int, since nobody uses the return value.
896 * textprop.c (validate_plist, add_properties, remove_properties)
897 (Fadd_text_properties):
898 Don't assume list length fits in int.
899 (interval_has_all_properties, interval_has_some_properties)
900 (interval_has_some_properties_list, add_properties, remove_properties)

910 Implement CLASH_DETECTION for MS-Windows.
912 * filelock.c [WINDOWSNT]: Include w32.h.
913 (MAKE_LOCK_NAME): Don't use 'lock', it clashes with MS runtime
914 function of that name. Up-case the macro arguments.
915 (IS_LOCK_FILE): New macro.
916 (fill_in_lock_file_name): Use IS_LOCK_FILE instead of S_ISLNK.
917 (create_lock_file): New function, with body extracted from
919 [WINDOWSNT]: Implement lock files by writing a regular file with
920 the lock information as its contents.
921 (read_lock_data): New function, on Posix platforms just calls
923 [WINDOWSNT]: Read the lock info from the file.
924 (current_lock_owner): Call read_lock_data instead of calling
925 emacs_readlinkat directly.
926 (lock_file) [WINDOWSNT]: Run the file name through
929 * w32proc.c (sys_kill): Support the case of SIG = 0, in which case
930 just check if the process by that PID exists.
932 * w32.c (sys_open): Don't reset the _O_CREAT flag if _O_EXCL is
933 also present, as doing so will fail to error out if the file
936 * makefile.w32-in ($(BLD)/filelock.$(O)): Depend on src/w32.h.
938 * textprop.c (Fadd_text_properties, Fremove_text_properties)
939 (Fremove_list_of_text_properties): Skip all of the intervals in
940 the region between START and END that already have resp. don't
941 have the requested properties, not just the first one.
942 Add assertions that the loop afterwards always modifies the
943 properties. (Bug#13743)
945 2013-02-25 Stefan Monnier <monnier@iro.umontreal.ca>

955 * Makefile.in (LD_FIRSTFLAG, LIB_GCC, CRT_DIR, LIB_STANDARD)
956 (START_FILES): Remove. All uses removed.
957 (otherobj): Remove $(VMLIMIT_OBJ), as it's now first.
958 (ALLOBJS): Move here from autodeps.mk, and with VMLIMITS_OBJ first.
959 (buildobj.h): Use it.
960 ($(ALLOBJS)): Depend on globals.h.
961 (temacs$(EXEEXT)): Use $(ALLOBJS).
962 * autodeps.mk (ALLOBJS): Move to Makefile.in.
963 * deps.mk (vm-limit.o):
964 * makefile.w32-in ($(BLD)/vm-limit.$(O)):
965 Do not depend on mem-limits.h.
966 * emacs.c (__do_global_ctors, __do_global_ctors_aux)
967 (__do_global_dtors, __CTOR_LIST__, __DTOR_LIST__)
968 [__GNUC__ && !ORDINARY_LINK]: Remove.

972 (make_hdr): Use DATA_START instead of start_of_data.
973 * vm-limit.c: Move most of mem-limits.h's contents here.
974 (data_start): New decl. It's OK if this is approximate,
975 so simplify-away some unnecessary exactness.
976 (POINTER): Remove; all uses removed.
977 (data_space_start): Now char *, to avoid casts.
978 (exceeds_lisp_ptr): New function, replacing the old
979 EXCEEDS_LISP_PTR macro. All uses changed.
980 (check_memory_limits): Simplify and remove casts.
981 (start_of_data) [!CANNOT_DUMP || !SYSTEM_MALLOC]: Remove.

995 and diagnosed by Andreas Schwab in
996 <http://lists.gnu.org/archive/html/emacs-devel/2013-02/msg00534.html>.
998 2013-02-22 Paul Eggert <eggert@cs.ucla.edu>
1000 Assume C89 or better.
1001 * ralloc.c (SIZE, POINTER, NIL):
1002 * vm-limit.c (POINTER):
1003 Remove, replacing all uses with C89 equivalents. These old
1004 symbols were present only for porting to pre-C89 platforms.
1006 2013-02-22 Claudio Bley <claudio.bley@gmail.com>
1008 * w32.c (emacs_gnutls_pull): Don't call 'select', and don't loop.
1009 This avoids warning messages reported as part of Bug#13546.
1011 2013-02-21 Ken Brown <kbrown@cornell.edu>
1013 * sheap.c (report_sheap_usage): Fix arguments of message1_no_log.
1015 2013-02-20 Stefan Monnier <monnier@iro.umontreal.ca>
1017 * sheap.c (report_sheap_usage): Prefer message1_nolog.

1024 2013-02-19 Daniel Colascione <dancol@dancol.org>
1026 * sheap.c (report_sheap_usage): Use message, not message1, so
1027 that we don't try to create a buffer while we're in the middle
1028 of dumping Emacs. Explain why.
1030 2013-02-20 Dmitry Antipov <dmantipov@yandex.ru>
1032 * search.c (find_newline): Return byte position in bytepos.

1042 (get_visually_first_element, move_it_vertically_backward):
1043 Adjust users and avoid calls to CHAR_TO_BYTE where appropriate.
1045 2013-02-19 Eli Zaretskii <eliz@gnu.org>
1047 * w32proc.c (new_child): Avoid leaking handles if the subprocess
1048 resources were not orderly released.
1050 2013-02-17 Eli Zaretskii <eliz@gnu.org>
1052 * xdisp.c (x_draw_vertical_border): For a window that is neither
1053 the leftmost nor the rightmost, redraw both the left and the right
1054 vertical borders. (Bug#13723)
1056 2013-02-17 Stefan Monnier <monnier@iro.umontreal.ca>
1058 * xml.c (init_libxml2_functions):

1065 * editfns.c (Fmessage, Fmessage_box):
1066 * callint.c (Fcall_interactively):
1067 * fns.c (Fyes_or_no_p): Prefer `message1' over `message'.
1069 2013-02-17 Jan Djärv <jan.h.d@swipnet.se>
1071 * xterm.c (syms_of_xterm): Move scroll-bar-adjust-thumb-portion ...
1072 * frame.c (syms_of_frame): ... to here.
1074 2013-02-16 Eli Zaretskii <eliz@gnu.org>
1076 * w32.c (sys_chown): Remove unused function.

1079 unconditionally. (Bug#9066)
1081 * w32.c (set_errno): Reset h_errno and don't set it to any other
1082 value. Set errno instead.
1083 (check_errno): Reset h_errno.
1084 (sys_socket, socket_to_fd, sys_bind, sys_connect)
1085 (sys_gethostname, sys_getservbyname, sys_getpeername)
1086 (sys_shutdown, sys_setsockopt, sys_listen, sys_getsockname)
1087 (sys_accept, sys_recvfrom, sys_sendto, fcntl, sys_read): Don't set
1089 (sys_gethostbyname): Set h_errno only errors detected.
1091 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
1093 * process.c (h_errno) [!HAVE_H_ERRNO]: Remove unused decl.
1095 2013-02-15 Eli Zaretskii <eliz@gnu.org>
1097 * keyboard.c (read_char): Fix calculation of auto-save time out
1098 when auto-save-timeout is less than 4. (Bug#13720)
1100 * w32proc.c (new_child): Free up to 2 slots of dead processes at a
1101 time. Improve diagnostics in DebPrint. (Bug#13546)

1122 (get_overlay_arrow_glyph_row, display_mode_element):
1123 (decode_mode_spec_coding, message3):
1124 * xfaces.c (face_at_string_position): Use bool for booleans.
1127 2013-02-15 Paul Eggert <eggert@cs.ucla.edu>
1129 Fix AIX port (Bug#13650).
1130 * lisp.h (XPNTR) [!USE_LSB_TAG && DATA_SEG_BITS]:
1131 Fix bug introduced in 2012-07-27 change. DATA_SEG_BITS, if set,
1132 was #undeffed earlier, so it cannot be used as a macro here.
1133 Use the constant and not the macro.
1135 2013-02-15 Eli Zaretskii <eliz@gnu.org>
1137 * w32proc.c (new_child): If no vacant slots are found in
1138 child_procs[], make another pass looking for slots whose process
1139 has exited or died. (Bug#13546)
1141 * w32.c (sys_pipe): When failing due to file descriptors above
1142 MAXDESC, set errno to EMFILE.
1143 (_sys_read_ahead): Update cp->status when failing to read serial
1144 communications input, so that the status doesn't stay at
1145 STATUS_READ_IN_PROGRESS. (Bug#13546)
1147 2013-02-14 Jan Djärv <jan.h.d@swipnet.se>
1149 * gtkutil.c (tb_size_cb): New function.

1152 2013-02-14 Stefan Monnier <monnier@iro.umontreal.ca>
1154 * keyboard.c (active_maps): Fcurrent_active_maps expects a position, not
1157 2013-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
1159 * keyboard.c (syms_of_keyboard): Further tweaks of docstring.
1161 2013-02-13 Dmitry Antipov <dmantipov@yandex.ru>

1165 * font.h (font_range): Adjust prototype.
1166 * composite.c (autocmp_chars): Pass byte position to font_range.
1167 Break long line. Remove useless prototype and format comment.
1169 2013-02-13 Glenn Morris <rgm@gnu.org>
1171 * keyboard.c (input-decode-map, key-translation-map): Doc fixes.
1173 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
1175 Improve AIX port some more (Bug#13650).
1176 With this, it should be as good as it was in 23.3, though it's
1177 still pretty bad: the dumped emacs does not run. See Mark Fleishman in
1178 http://lists.gnu.org/archive/html/help-gnu-emacs/2011-04/msg00287.html
1179 * unexaix.c (start_of_text): Remove.
1180 (_data, _text): Declare as char[], not int, as AIX manual suggests.
1181 (bias, lnnoptr, text_scnptr, data_scnptr, load_scnptr)
1182 (orig_load_scnptr, orig_data_scnptr):
1183 Now off_t, not long, since they are file offsets.
1184 (make_hdr): Use _data, not start_of_data ().
1185 This is the key part of the fix.
1186 (make_hdr, unrelocate_symbols): Use off_t for file offsets.
1187 (unrelocate_symbols): Cast pointers to intptr_t, not to ulong.
1189 * pre-crt0.c (data_start): Initialize to 1.
1190 This ports to compilers that optimize the external declaration
1191 'int x = 0;' as if it were 'int x;' to shrink the executable.
1193 Improve AIX port (Bug#13650).
1194 This doesn't fix the bug, but it makes progress: Emacs builds now.
1195 * unexaix.c: Include inttypes.h, stdarg.h.
1196 (report_error, report_error_1): Mark as _Noreturn.
1197 (report_error): Don't report the wrong errno.
1198 (report_error_1): Now varargs. All callers changed.
1199 (make_hdr): Use uintptr_t, not unsigned, when converting pointers
1200 to unsigned. Don't use ADDR_CORRECT, as it no longer exists.
1201 (write_ptr): Use %p to print address rather than %lx and a cast
1202 to unsigned long. Grow buffer a bit, to be safer.
1204 2013-02-13 Eli Zaretskii <eliz@gnu.org>
1206 * bidi.c (bidi_resolve_neutral): After finding the next
1207 non-neutral character, accept NEUTRAL_ON type as well, because
1208 directional control characters, such as LRE and RLE, have their
1209 type converted to that by bidi_resolve_weak. This avoids aborts
1210 when LRE/RLE follows a run of neutrals.
1211 (bidi_move_to_visually_next): Assert that return value of
1212 bidi_peek_at_next_level is non-negative. Negative values will
1215 2013-02-13 Paul Eggert <eggert@cs.ucla.edu>
1217 Minor getenv-related fixes.
1218 * callproc.c (Fcall_process_region) [!DOS_NT]:
1219 Avoid unnecessary duplicate call to getenv.
1220 * callproc.c (init_callproc):
1221 * dispnew.c (init_display):
1222 * sysdep.c (sys_subshell):
1223 Omit unnecessary cast of getenv or egetenv.
1225 2013-02-13 Juanma Barranquero <lekktu@gmail.com>
1227 * makefile.w32-in ($(BLD)/filelock.$(O), $(BLD)/sysdep.$(O)):
1228 Update dependencies.
1230 2013-02-12 Eli Zaretskii <eliz@gnu.org>
1232 * xdisp.c (redisplay_internal): Don't set w->region_showing to the
1234 (display_line): Set w->region_showing to the value of
1235 it->region_beg_charpos, not to -1. This fixes redisplay
1236 optimization when cursor is moved up after M->. (Bug#13623)
1238 (try_scrolling): Scroll text up more if point is too close to ZV
1239 and inside the scroll margin. This makes sure point is moved
1240 outside the scroll margin in these cases.
1242 * window.h (struct window): region_showing can no longer be
1245 2013-02-11 Paul Eggert <eggert@cs.ucla.edu>
1247 Tune by using memchr and memrchr.
1248 * doc.c (Fsnarf_documentation):
1249 * fileio.c (Fsubstitute_in_file_name):
1250 * search.c (find_newline, scan_newline):
1251 * xdisp.c (pos_visible_p, display_count_lines):
1252 Use memchr and memrchr rather than scanning byte-by-byte.
1253 * search.c (find_newline): Rename from scan_buffer.
1254 Omit first arg TARGET, as it's always '\n'. All callers changed.
1256 Clean up read_key_sequence a tiny bit more.
1257 * keyboard.c (read_char_x_menu_prompt) [HAVE_MENUS]:
1258 (read_key_sequence): Remove unused locals.
1260 2013-02-11 Stefan Monnier <monnier@iro.umontreal.ca>
1262 Clean up read_key_sequence a bit; reread active keymaps after first event.
1263 * keyboard.c (read_char, read_char_x_menu_prompt)
1264 (read_char_minibuf_menu_prompt):
1265 Replace nmaps+maps with a single `map' arg.
1266 (follow_key): Operate on a single map.
1267 (active_maps): New function.
1268 (test_undefined): Also return true for nil bindings.
1269 (read_key_sequence): Use active_maps to replace the arrays of keymaps with
1270 a single (composed) keymap. Remember `first_event' to choose the right
1271 set of active keymaps. Recompute the set of keymaps after receiving
1272 the first event. Remove GOBBLE_FIRST_EVENT.
1273 (syms_of_keyboard): Remove inhibit_local_menu_bar_menus.
1274 * keyboard.h (read_char): Update declaration.
1275 * lread.c (read_filtered_event): Adjust call to read_char.
1277 2013-02-11 Eli Zaretskii <eliz@gnu.org>
1279 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
1280 Don't use the limitation on backwards movement when lines are truncated
1281 in the window. (Bug#13675)
1283 2013-02-11 Dmitry Antipov <dmantipov@yandex.ru>
1285 * marker.c (set_marker_internal): If desired position is passed
1286 as a marker, avoid call to buf_charpos_to_bytepos.
1287 * window.c (Fset_window_point): Omit redundant type checking.
1288 (Fset_window_start): Likewise. Format comment.
1289 (window_scroll_pixel_based): Use set_marker_restricted_both
1290 with character and byte positions obtained from an iterator.
1291 (Fset_window_configuration): Use set_marker_restricted_both.
1292 * xdisp.c (message_dolog): Likewise.
1294 2013-02-10 Eli Zaretskii <eliz@gnu.org>
1296 * xdisp.c (move_it_vertically_backward, move_it_by_lines):
1297 When text lines are longer than window's screen lines, don't move back
1298 too far. This speeds up some redisplay operations. (Bug#13675)
1300 2013-02-10 Dmitry Antipov <dmantipov@yandex.ru>
1302 * syntax.c (scan_sexps_forward): Fix byte position calculation
1303 Bug#13664 (a.k.a Bug#13667) introduced with 2013-02-08 change.
1305 2013-02-10 Paul Eggert <eggert@cs.ucla.edu>

1308 that was not needed.
1310 2013-02-09 Paul Eggert <eggert@cs.ucla.edu>
1312 Minor hashing refactoring.
1313 * fns.c (SXHASH_REDUCE): Move to lisp.h.
1314 (sxhash_float): Return EMACS_UINT, for consistency with the other
1316 * lisp.h (INTMASK): Now a macro, since SXHASH_REDUCE is now a
1317 non-static inline function and therefore can't use static vars.
1318 (SXHASH_REDUCE): Move here from fns.c, and make it inline.
1319 * profiler.c (hashfn_profiler): Use SXHASH_REDUCE, to be consistent
1320 with the other hash functions.
1322 2013-02-09 Eli Zaretskii <eliz@gnu.org>
1324 * callproc.c (Fcall_process_region) [WINDOWSNT]: Make sure the
1325 XXXXXX part of the temporary file pattern is not downcased even
1326 when w32-downcase-file-names is non-nil. (Bug#13661)
1328 * xdisp.c (decode_mode_spec): Remove handling of %t.

1377 * nsmenu.m (update_frame_tool_bar): Check for negative tool bar
1380 * nsterm.h (HAVE_NATIVE_FS): Define if OSX => 10.7.

1403 (fsIsNative, isFullscreen, updateCollectionBehaviour): New methods.
1404 (toggleFullScreen:): If fs_is_native, call toggleFullScreen on
1405 window. Do no set FRAME_EXTERNAL_TOOL_BAR (f) to 0.
1406 Check FRAME_EXTERNAL_TOOL_BAR (f) before restoring
1407 FRAME_TOOLBAR_HEIGHT (f). Call updateFrameSize when going non-fs.
1408 (syms_of_nsterm): Add ns-use-native-fullscreen.
1410 2013-02-04 Paul Eggert <eggert@cs.ucla.edu>
1412 * fileio.c (Qchoose_write_coding_system): Now static.
1414 2013-02-04 Eli Zaretskii <eliz@gnu.org>
1416 * xdisp.c (window_buffer_changed): region_showing can be negative,
1417 which still means region is being displayed.
1418 (redisplay_internal): Resurrect code that forced redisplay of the
1419 whole window when showing region and the mark has changed.
1420 Record the new mark position to allow redisplay optimizations.
1421 (display_line): If it->region_beg_charpos is non-zero, set the
1422 window's region_showing member to -1. (Bug#13623) (Bug#13626)
1424 * window.h (struct window) <region_showing>: Declare ptrdiff_t,
1425 not bitfield of 1 bit.
1427 2013-02-03 Daniel Colascione <dancol@dancol.org>
1429 * emacs.c: Use execvp, not execv, when DAEMON_MUST_EXEC, so that
1430 daemon mode works on cygw32 when Emacs is installed and not just
1433 2013-02-02 Paul Eggert <eggert@cs.ucla.edu>
1435 Avoid file time stamp bug on MS-Windows (Bug#13149).
1436 * fileio.c (Fwrite_region): Don't use the heuristic on empty files,
1437 as FAT32 doesn't update time stamps when truncating them.
1438 Also, check that a file time stamp is not a multiple of 100 ns;
1439 this should catch all instances of the problem on MS-Windows,
1440 as its native file system resolution is 100 ns or worse, and
1441 checking for a non-multiple of 100 ns should impose only a small
1442 overhead on systems with ns resolution.
1444 2013-02-02 Eli Zaretskii <eliz@gnu.org>
1446 Avoid encoding file names on MS-Windows when they need to be run
1447 through dostounix_filename.
1448 * w32.c (normalize_filename): Accept an additional argument
1449 MULTIBYTE; if non-zero, traverse the file name by bytes and don't
1450 downcase it even if w32-downcase-file-names is non-nil.
1451 (dostounix_filename): Accept an additional argument MULTIBYTE and
1452 pass it to normalize_filename.
1453 (emacs_root_dir): Adjust.
1455 * msdos.h (dostounix_filename): Adjust prototype.
1457 * w32.h (dostounix_filename): Adjust prototype.
1459 * msdos.c (dostounix_filename): Accept an additional argument and
1461 (init_environment): Adjust callers of dostounix_filename.
1463 * fileio.c (Ffile_name_directory, file_name_as_directory)
1464 (directory_file_name, Fexpand_file_name)
1465 (Fsubstitute_in_file_name): [DOS_NT] Adjust call to
1467 [WINDOWSNT]: Downcase file names if w32-downcase-file-names is
1469 (Fsubstitute_in_file_name): [DOS_NT] Don't downcase environment
1470 variables, as egetenv is case-insensitive for DOS_NT.
1472 * dired.c (file_name_completion): Don't call Fdirectory_file_name
1473 with an encoded file name.
1475 * w32proc.c (Fw32_short_file_name, Fw32_long_file_name):
1476 Adjust calls to dostounix_filename.
1478 * w32fns.c (Fx_file_dialog): Adjust call to dostounix_filename.
1480 * unexw32.c (unexec): Adjust call to dostounix_filename.
1482 * termcap.c (tgetent) [MSDOS]: Adjust call to dostounix_filename.
1484 * emacs.c (decode_env_path) [DOS_NT]: Adjust call to
1487 * callproc.c (Fcall_process) [MSDOS]: Adjust call to
1490 * callproc.c (Fcall_process): Make sure program name in PATH and
1491 new_argv[0] is encoded, if needed. Otherwise, un-encoded string
1492 is passed to exec/spawnve, which fails unless the file-name
1495 * w32proc.c (sys_spawnve): Make sure escape_char is initialized,
1496 even if w32-quote-process-args is nil.
1498 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
1500 Fix timestamp bug when write-region appends nothing (Bug#13149).
1501 * fileio.c (Fwrite_region): When neither O_EXCL nor O_TRUNC is used,
1502 the file's time stamp doesn't change if Emacs happens to write nothing
1503 to the file, and on a buggy file system this could cause Emacs to
1504 incorrectly infer that the file system doesn't have the bug.
1505 Avoid this problem by inhibiting the inference in this case.
1507 2013-02-01 Dmitry Antipov <dmantipov@yandex.ru>
1509 * window.h (struct window): Convert base_line_number, base_line_pos
1510 and column_number_displayed members from Lisp_Object to ptrdiff_t.
1511 Convert region_showing member from Lisp_Object to bitfield.
1512 Remove sequence_number member. Adjust comments.
1513 * window.c (sequence_number): Remove.
1514 (make_window): Initialize column_number_displayed.
1515 * print.c (print_object): Follow the printed representation of
1516 frames and print window pointer to distinguish between windows.
1517 (adjust_window_count): Invalidate base_line_pos. Adjust comment.
1518 * xdisp.c (wset_base_line_number, wset_base_line_pos)
1519 (wset_column_number_displayed, wset_region_showing): Remove.
1520 (window_buffer_changed, mode_line_update_needed, redisplay_internal)
1521 (try_scrolling, try_cursor_movement, redisplay_window)
1522 (try_window_reusing_current_matrix, try_window_id, display_line)
1523 (display_mode_lines, decode_mode_spec): Adjust users.
1524 * .gdbinit (pwinx): Do not print sequence_number.
1526 2013-02-01 Paul Eggert <eggert@cs.ucla.edu>
1528 Use fdopendir, fstatat and readlinkat, for efficiency (Bug#13539).
1529 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): Remove.
1530 * dired.c: Include <fcntl.h>.
1531 (open_directory): New function, which uses open and fdopendir
1532 rather than opendir. DOS_NT platforms still use opendir, though.
1533 (directory_files_internal, file_name_completion): Use it.
1534 (file_attributes): New function, with most of the old Ffile_attributes.
1535 (directory_files_internal, Ffile_attributes): Use it.
1536 (file_attributes, file_name_completion_stat): First arg is now fd,
1537 not dir name. All uses changed. Use fstatat rather than lstat +
1539 (file_attributes): Use emacs_readlinkat rather than Ffile_symlink_p.
1540 * fileio.c: Include <allocator.h>, <careadlinkat.h>.
1541 (emacs_readlinkat): New function, with much of the old
1542 Ffile_symlink_p, but with an fd argument for speed.
1543 It uses readlinkat rather than careadlinkatcwd, so that it
1544 need not assume the working directory.
1545 (Ffile_symlink_p): Use it.
1546 * filelock.c (current_lock_owner): Use emacs_readlinkat
1547 rather than emacs_readlink.
1548 * lisp.h (emacs_readlinkat): New decl.
1549 (READLINK_BUFSIZE, emacs_readlink): Remove.
1550 * sysdep.c: Do not include <allocator.h>, <careadlinkat.h>.
1551 (emacs_norealloc_allocator, emacs_readlink): Remove.
1552 This stuff is moved to fileio.c.
1553 * w32.c (fstatat, readlinkat): New functions.
1554 (careadlinkat): Don't check that fd == AT_FDCWD.
1555 (careadlinkatcwd): Remove; no longer needed.
1557 2013-01-31 Glenn Morris <rgm@gnu.org>
1559 * fileio.c (choose_write_coding_system): Make it callable from Lisp.
1560 (Fwrite_region): Update for new choose_write_coding_system args.
1561 Move the last piece of choose_write_coding_system here. (Bug#13522)
1562 (syms_of_fileio): Add choose-write-coding-system.
1564 2013-01-30 Eli Zaretskii <eliz@gnu.org>
1566 * w32.c (sys_open): Zero out the flags for the new file descriptor.
1567 (sys_close): Zero out the flags for the file descriptor before
1568 closing it. (Bug#13546)
1570 * w32.c (parse_root, get_volume_info, readdir, read_unc_volume)
1571 (logon_network_drive, stat_worker, symlink, chase_symlinks):
1572 Use CharNextExA and CharPrevExA to iterate over file names encoded in
1575 * w32.c (w32_get_long_filename, init_environment, readlink):
1576 Support file names encoded in DBCS codepages.
1577 (readlink): Use the current file-name-coding-system, not the ANSI
1578 codepage, to decode and handle targets of symlinks.
1580 2013-01-28 Eli Zaretskii <eliz@gnu.org>
1582 * w32.c (opendir): Now accepts a 'const char *'.
1584 2013-01-28 Dmitry Antipov <dmantipov@yandex.ru>
1586 Remove obsolete redisplay code. See the discussion at
1587 http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00576.html.
1588 * dispnew.c (preemption_period, preemption_next_check): Remove.
1589 (Vredisplay_preemption_period): Likewise.
1590 (update_frame, update_single_window, update_window, update_frame_1):
1591 Adjust users. Always assume that PERIODIC_PREEMPTION_CHECKING is not
1592 used, following the 2012-06-22 change.
1594 2013-01-25 Eli Zaretskii <eliz@gnu.org>
1596 * w32notify.c (Fw32notify_add_watch): Doc fix. (Bug#13540)
1598 2013-01-25 Dmitry Antipov <dmantipov@yandex.ru>
1600 * font.c (num_fonts): Remove the leftover from old
1601 debugging code. Adjust comment style here and there.
1602 * insdel.c (insert_1): Remove.
1603 * lisp.h (insert_1): Remove prototype.
1604 * xdisp.c (message_dolog): Adjust users to call insert_1_both.
1606 2013-01-25 Eli Zaretskii <eliz@gnu.org>
1608 * w32.c (max_filename_mbslen): New function.
1609 (normalize_filename, readdir): Use it to detect locales where ANSI
1610 encoding of file names uses a double-byte character set (DBCS).
1611 If a DBCS encoding is used, advance by characters using
1612 CharNextExA, instead of incrementing a 'char *' pointer.
1613 Use _mbslwr instead of _strlwr. (Bug#13515)
1615 * w32heap.c (allocate_heap) [!_WIN64]: Decrease the initial
1616 request of memory reservation to 1.7GB. (Bug#13065)
1618 2013-01-25 Andreas Schwab <schwab@linux-m68k.org>
1620 * coding.c (detect_coding_iso_2022): Move back mis-reordered code
1621 at check_extra_latin label. (Bug#13505)
1623 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1625 * nsfont.m (ns_escape_name, ns_unescape_name, ns_registry_to_script):
1626 Avoid redundant calls to strlen.
1628 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1630 Drop async_visible and async_iconified fields of struct frame.
1631 This is possible because async input is gone; for details, see
1632 http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00734.html.
1633 * frame.h (struct frame): Remove async_visible and async_iconified
1634 members, convert garbaged to unsigned bitfield. Adjust comments.
1635 (FRAME_SAMPLE_VISIBILITY): Remove. Adjust all users.
1636 (SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED): New macros.
1637 * frame.c, gtkutil.c, term.c, w32fns.c, window.c, xdisp.c:
1638 Consistently use SET_FRAME_VISIBLE, SET_FRAME_ICONIFIED,
1639 FRAME_VISIBLE_P and FRAME_ICONIFIED_P macros where appropriate.
1641 (w32_read_socket): Save iconified state to generate DEICONIFY_EVENT
1642 properly. Likewise for obscured.
1644 (handle_one_xevent): Save visible state to generate ICONIFY_EVENT
1647 (windowDidDeminiaturize): Generate DEICONIFY_EVENT.
1649 2013-01-24 Dmitry Antipov <dmantipov@yandex.ru>
1651 * insdel.c (prepare_to_modify_buffer): Revert last change as suggested
1652 in http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00555.html.
1654 2013-01-23 Stefan Monnier <monnier@iro.umontreal.ca>
1656 * xdisp.c (message2, message2_nolog): Remove functions.
1657 (message3, message3_nolog): Extract nbytes and multibyteness directly
1658 from the string. Change all callers.
1659 (message3_nolog): Don't set message_enable_multibyte since set_message
1660 will reset it anyway.
1661 (message1, message1_nolog): Use message3.
1662 (vmessage): Use a stack allocated buffer rather than f->message_buf.
1663 (with_echo_area_buffer): Remove last two arguments. Update all callers.
1664 (set_message): Drop all but the second arg, which has to be a string.
1665 (set_message_1): Simplify now that we know that a1 is NULL and the
1666 second arg is a string.
1667 * frame.h (struct frame): Remove `message_buf' field.
1668 Use glyphs_initialized_p instead.
1669 (FRAME_MESSAGE_BUF): Remove macro.
1670 * w16select.c (Fw16_set_clipboard_data): Prefer message3 to message2.
1671 * lisp.h (message2, message2_nolog): Remove declarations.
1672 (message3, message3_nolog): Update declarations.
1673 * keyboard.c (read_char_minibuf_menu_text)
1674 (read_char_minibuf_menu_width): Remove vars.
1675 (read_char_minibuf_menu_prompt): Rewrite the menu's construction so as
1676 to correctly handle multibyte strings.
1677 * frame.c (delete_frame): Don't free message_buf any more.
1678 * editfns.c (message_text, message_length): Remove vars.
1679 (Fmessage_box): Don't copy the Lisp string's bytes any longer.
1680 * fileio.c (auto_save_error): Use message3 instead of message2.
1681 * dispnew.c (adjust_frame_message_buffer): Remove function.
1683 2013-01-23 Eli Zaretskii <eliz@gnu.org>
1685 * w32term.c (w32fullscreen_hook): Account correctly for the screen
1686 real estate used for the tool bar and the menu bar.
1688 2013-01-23 Dmitry Antipov <dmantipov@yandex.ru>
1690 * insdel.c (prepare_to_modify_buffer): Force redisplay if
1691 hidden buffer is prepared to modification (Bug#13164).
1693 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
1695 * window.h (struct window): Change window_end_valid member from
1696 Lisp_Object to a bitfield. Adjust comments.
1697 (wset_window_end_valid): Remove.
1698 * window.c (adjust_window_count): Clear window_end_valid.
1699 (Fwindow_end): Adjust user. Remove ancient #if 0 code.
1700 (Fwindow_line_height, set_window_buffer, Frecenter)
1701 (Fsplit_window_internal, Fdelete_other_windows_internal)
1702 (Fset_window_fringes, Fset_window_scroll_bars): Adjust users.
1703 * dispnew.c (adjust_glyph_matrix, clear_window_matrices): Likewise.
1704 * xdisp.c (check_window_end, reconsider_clip_changes)
1705 (redisplay_internal, mark_window_display_accurate_1, redisplay_window)
1706 (try_window, try_window_reusing_current_matrix, note_mouse_highlight)
1707 (find_first_unchanged_at_end_row, try_window_id): Likewise.
1709 2013-01-22 Dmitry Antipov <dmantipov@yandex.ru>
1711 * xdisp.c (mark_window_display_accurate): Simplify the loop
1712 assuming that the only one of vchild, hchild or buffer window
1713 slots is non-nil. Call mark_window_display_accurate_1 for
1714 the leaf windows only.
1715 (mark_window_display_accurate_1): Always assume leaf window.
1718 2013-01-22 Paul Eggert <eggert@cs.ucla.edu>
1720 * emacs.c (Qkill_emacs_hook): Now static.
1722 * fileio.c (Finsert_file_contents): Simplify.
1723 Remove unnecessary assignments and tests.
1725 2013-01-21 Eli Zaretskii <eliz@gnu.org>
1727 * w32.c (acl_set_file): Don't test for errors unless
1728 set_file_security returns FALSE. Avoids spurious errors when
1731 2013-01-21 Dmitry Antipov <dmantipov@yandex.ru>
1733 * fileio.c (Finsert_file_contents): Revert code introduced at
1734 2013-01-18 in favor of the simpler and generally better fix.
1735 Save stack space by removing 'buffer' and reusing 'read_buf'
1738 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1740 * lisp.h (eabs): Define unconditionally (Bug#13419).
1741 The old "#if !defined (eabs)" was an unnecessary revenant of back
1742 when this macro was called "abs". Document 'eabs' better.
1744 2013-01-19 Glenn Morris <rgm@gnu.org>
1746 * fns.c (Frandom): Doc fix.
1748 2013-01-19 Eli Zaretskii <eliz@gnu.org>
1750 * editfns.c (get_pos_property): Use SAFE_ALLOCA_LISP, to avoid
1751 segfault when there are lots of overlays.
1753 * buffer.c (sort_overlays): Use SAFE_NALLOCA, to avoid segfault
1754 when there are lots of overlays.
1755 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00421.html
1756 for the details and a way to reproduce.
1758 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1760 * fileio.c: Use O_APPEND to append.
1761 This corresponds better to the natural interpretation of "append",
1762 and avoids the need to open the output file twice, or to invoke
1763 lseek when APPEND is neither nil nor a number.
1764 This relies on POSIX 1003.1-1988 or later, which is OK nowadays.
1765 (Fwrite_region): Simplify. Use O_APPEND instead of opening the
1766 file possibly twice, and lseeking to its end; this avoids the
1767 need to lseek on non-regular files. Do not use O_EXCL and O_TRUNC
1768 at the same time: the combination is never needed and apparently
1769 it doesn't work with DOS_NT.
1771 Fix size bug on DOS_NT introduced by CIFS workaround (Bug#13149).
1772 * fileio.c (Fwrite_region): Use O_BINARY in checking code, too.
1774 Allow floating-point file offsets.
1775 Problem reported by Vitalie Spinu in
1776 <http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00411.html>.
1777 * fileio.c (emacs_lseek): Remove.
1778 (file_offset): New function.
1779 (Finsert_file_contents, Fwrite_region): Use it.
1781 2013-01-19 Chong Yidong <cyd@gnu.org>
1783 * emacs.c (Fkill_emacs): Set waiting_for_input to 0 to avoid
1784 aborting on Fsignal (Bug#13289).
1786 2013-01-19 Eli Zaretskii <eliz@gnu.org>
1788 * w32.c (acl_set_file): Treat ERROR_ACCESS_DENIED from
1789 set_file_security as failure due to insufficient privileges.
1790 Reported by Fabrice Popineau <fabrice.popineau@supelec.fr>.
1791 (fstat): Return owner and group like 'stat' and 'lstat' do.
1793 2013-01-19 Paul Eggert <eggert@cs.ucla.edu>
1795 Work around bug in CIFS and vboxsf file systems (Bug#13149).
1796 The bug was observed on Ubuntu operating inside a virtual machine,
1797 editing files mounted via CIFS or vboxsf from the MS Windows 7 host.
1798 The workaround introduces a race condition on non-buggy hosts,
1799 but it's an unlikely race and anyway there's a nearly identical
1800 nearby race that can't be fixed.
1801 * fileio.c (valid_timestamp_file_system, timestamp_file_system):
1803 (Fwrite_region): Test for file system time stamp bug.
1804 (init_fileio): New function.
1805 * lisp.h (init_fileio): Declare it.
1806 * emacs.c (main): Call it.
1808 * fileio.c (Finsert_file_contents): Simplify new diagnostic
1809 and make it more consistent with other stat-failure diagnostics.
1811 2013-01-18 Dmitry Antipov <dmantipov@yandex.ru>
1813 Fix crash when inserting data from non-regular files.
1814 See http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00406.html
1815 for the error description produced by valgrind.
1816 * fileio.c (read_non_regular): Rename to read_contents.
1817 Free Lisp_Save_Value object used to pass parameters.
1818 (read_non_regular_quit): Rename to read_contents_quit.
1819 (Finsert_file_contents): Redesign internal file reading loop to adjust
1820 gap and end positions after each read and so help make_gap to work
1821 properly. Do not signal an I/O error too early and so do not leave
1822 not yet decoded characters in a buffer, which was the reason of
1823 redisplay crash. Use list2 to build return value. Adjust comments.
1825 2013-01-17 Paul Eggert <eggert@cs.ucla.edu>
1827 Close a race when statting and reading files (Bug#13149).
1828 * fileio.c (Finsert_file_contents): Use open+fstat, not stat+open.
1829 This avoids a race if the file is renamed between stat and open.
1830 This race is not the problem originally noted in Bug#13149;
1831 see <http://bugs.gnu.org/13149#73> and later messages in the thread.
1833 2013-01-17 Dmitry Antipov <dmantipov@yandex.ru>
1835 * lisp.h (toplevel): Add comment about using Lisp_Save_Value
1836 objects, related functions and macros.
1837 (make_save_value): Adjust prototype.
1838 (make_save_pointer): New prototype.
1839 (SAFE_NALLOCA): Fix indentation. Use make_save_pointer.
1840 (SAFE_ALLOCA_LISP): Adjust make_save_value usage.
1841 * alloc.c (format_save_value): Rename to make_save_value.
1842 (make_save_pointer): New function.
1843 (record_xmalloc): Use make_save_pointer.
1844 * dired.c, editfns.c, fileio.c, font.c, gtkutil.c, lread.c:
1845 * nsmenu.m, nsterm.m, xfns.c, xmenu.c, xselect.c, keymap.c:
1846 Change users of make_save_value to make_save_pointer.

2139 2012-12-31 Eli Zaretskii <eliz@gnu.org>
2141 * w32.c (unsetenv): Set up the string passed to _putenv
2143 See http://lists.gnu.org/archive/html/emacs-devel/2012-12/msg00863.html

2171 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2172 (xg_initialize): Initialize xg_detached_menus only if
2173 HAVE_GTK_TEAROFF_MENU_ITEM_NEW.
2175 * xterm.h (struct x_output): Surround handlebox_widget with
2176 #ifdef HAVE_GTK_HANDLE_BOX_NEW. toolbar_is_packed is new,

2215 * fileio.c (file_name_as_directory, directory_file_name):
2216 Accept an additional argument MULTIBYTE to indicate whether the input C

2218 adjusted. Don't assume the input string is always multibyte.
2220 (Ffile_name_directory) [DOS_NT]: Handle unibyte strings correctly:
2221 don't ENCODE_FILE them, and return a unibyte string if the input
2223 (Fexpand_file_name): Don't mix unibyte with multibyte strings, and
2224 don't assume the input strings will always be multibyte. If the

2241 * frame.h (enum output_method): Remove output_mac member since
2242 it's a leftover from the deleted code.
2243 * frame.c (Fframep): Adjust user here ...
2244 * terminal.c (Fterminal_live_p): ... and here.
2245 * coding.c (Qmac): Now here because it's only used to denote
2246 end-of-line encoding type.
2247 (syms_of_coding): DEFSYM it.
2248 * frame.h (Qmac): Remove duplicated declaration.
2250 2012-12-26 Paul Eggert <eggert@cs.ucla.edu>
2252 * window.c (select_window_1): Now static, since it's used only here.

2256 * window.c (window_body_cols): Subtract display margins from the
2257 window body width on TTYs as well. See
2258 http://lists.gnu.org/archive/html/help-gnu-emacs/2012-12/msg00317.html
2259 for the original report.
2261 2012-12-25 Dmitry Antipov <dmantipov@yandex.ru>
2263 * xdisp.c (redisplay_window): Remove inner local variable
2264 because the outer shadowed one has the same meaning.
2265 * xterm.h (struct x_output): Remove toolbar_detached member since it's
2267 * gtkutil.c (xg_tool_bar_detach_callback, xg_tool_bar_attach_callback)
2268 (xg_create_tool_bar): Adjust users.
2270 2012-12-24 Dmitry Antipov <dmantipov@yandex.ru>
2272 * buffer.h (BUF_COMPACT): New macro to follow the common style.
2273 * buffer.c (Fget_buffer_create): Use it to set compact field of
2274 struct buffer_text to avoid accessing an uninitialized value
2275 when compact_buffer is called for the first time.
2276 (compact_buffer): Use convenient BUF_COMPACT and BUF_MODIFF.
2277 (Fset_buffer_modified_p): Use buffer_window_count to check
2278 whether the buffer is displayed in some window.

2283 * w32.c (acl_set_file): If setting the file security descriptor
2284 fails, and the new DACL is identical to the existing one, silently

2289 * w32proc.c (reader_thread): Do not index fd_info[] with negative
2291 (reader_thread): Exit when cp->status becomes STATUS_READ_ERROR
2292 after WaitForSingleObject returns normally. This expedites reader
2293 thread shutdown when delete_child triggers it.
2294 (reap_subprocess): More accurate commentary for why we call
2295 delete_child only when cp->fd is negative.
2297 * w32.c (sys_close): Do not call delete_child on a subprocess
2298 whose handle is not yet closed. Instead, set its file descriptor
2299 to a negative value, so that reap_subprocess will call
2300 delete_child on that subprocess when its SIGCHLD arrives.
2301 This avoids closing handles used for communications between sys_select
2302 and reader_thread, which doesn't give sys_select a chance to
2303 notice that the process exited and invoke the SIGCHLD handler for
2306 2012-12-23 Jan Djärv <jan.h.d@swipnet.se>

2324 * fileio.c (Finsert_file_contents): Doc fix.
2326 * w32proc.c (new_child, delete_child, find_child_pid): For a
2327 subprocess, consider its slot being in use as long as its process
2328 handle (procinfo.hProcess) is not NULL. This avoids reusing the
2329 slot when a new process is started immediately after killing
2330 another one, without waiting enough time for the first process to
2331 be reaped and resources allocated for it be orderly freed.
2333 Suggested by Fabrice Popineau <fabrice.popineau@supelec.fr>.
2335 2012-12-21 Chong Yidong <cyd@gnu.org>

2346 Remove now unused argument FNAME; all callers changed.
2347 (get_file_owner_and_group): Remove now unused argument FNAME; all
2350 2012-12-21 Chong Yidong <cyd@gnu.org>
2352 * editfns.c (Finsert_char): Since read-char-by-name now signals an
2353 error for invalid chars, don't check for a nil return value.

2380 proper value of frame-local variables (bug#13225).
2382 2012-12-20 Dmitry Antipov <dmantipov@yandex.ru>
2384 * textprop.c (set_text_properties_1): Do not allow NULL interval.
2385 Rename 4th argument since it may be buffer or string. Adjust comment.
2386 * intervals.c (graft_intervals_info_buffer): Find an interval here.
2388 2012-12-19 Dmitry Antipov <dmantipov@yandex.ru>
2390 * coding.c (Fdetect_coding_region): Do not check start and end with
2391 CHECK_NUMBER_COERCE_MARKER since validate_region does that itself.
2392 (code_convert_region): Likewise.
2394 2012-12-18 Eli Zaretskii <eliz@gnu.org>
2396 * w32.c (acl_get_file, acl_set_file): Run the file name through
2397 map_w32_filename, and resolve any symlinks in the file name, like

2410 propagate redisplay's scrolling (if any) to the right window.
2411 (redisplay_internal): Use ensure_selected_frame.
2412 (display_mode_lines): Complete last fix.
2413 * window.c (select_window_1): New func, extracted from select_window.
2414 (select_window): Use it.
2415 * window.h (select_window_1): Declare.

2441 2012-12-17 Paul Eggert <eggert@cs.ucla.edu>
2443 Don't reraise SIGCHLD, as that can now lose (Bug#13192).
2444 With the 2012-12-03 fix for Bug#12980 in place, an old workaround
2445 for some of that bug's symptoms can now cause Emacs to abort.
2446 Remove the workaround.
2447 * process.c (wait_reading_process_output): Don't reraise SIGCHLD.
2448 The bug that caused SIGCHLD to get lost has been fixed, and the
2449 workaround for it can now cause Emacs to abort.
2451 2012-12-16 Paul Eggert <eggert@cs.ucla.edu>
2453 * sysdep.c (emacs_abort): Bump backtrace size to 40.
2454 Companion to the 2012-09-30 patch. Suggested by Eli Zaretskii in
2455 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00796.html>.

2491 * lisp.h (internal_delete_file): Adjust prototype.
2493 * callproc.c (Fcall_process): Don't overwrite infile with result
2495 [WINDOWSNT] If BUFFER is an integer, i.e. we are launching an
2496 asynchronous subprocess, record the name of the input file name,
2498 (delete_temp_file) [WINDOWSNT]: If internal_delete_file fails to
2499 delete the file, record it as pending deletion when the subprocess
2502 2012-12-14 Eli Zaretskii <eliz@gnu.org>
2504 * editfns.c [HAVE_PWD_H]: Include grp.h.

2510 Fix permissions bugs with setgid directories etc. (Bug#13125)
2511 * dired.c (Ffile_attributes): Return t as the 9th attribute,

2522 2012-12-14 Eli Zaretskii <eliz@gnu.org>
2524 * w32.c (stat_worker): If w32_stat_get_owner_group is zero, do not
2525 try to get accurate owner and group information from NT file
2526 security APIs. This is to make most callers of 'stat' and
2527 'lstat', which don't need that information, much faster.
2529 * dired.c (Ffile_attributes) [WINDOWSNT]:
2530 Set w32_stat_get_owner_group to a non-zero value, to request accurate
2531 owner and group information from 'lstat'.
2533 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2535 * fileio.c (Finsert_file_contents): Don't put tail into head area,
2536 as that confuses set-auto-coding, so insist on the head-read

2561 * fileio.c (Fvisited_file_modtime): Return (-1 ...) for nonexistent
2562 files, fixing a regression from 24.2.
2563 (Fverify_visited_file_modtime): Don't read uninitialized st.st_size.
2565 2012-12-13 Paul Eggert <eggert@cs.ucla.edu>
2567 * fileio.c (Fcopy_file): Make fstat failure as serious as open failure.
2568 fstat shouldn't fail, and if it does fail copy-file should not proceed.
2569 Remove unnecessary S_ISLNK test, as (contra the comments) this
2570 function can't copy symlinks. Improve quality of error message
2571 when attempting to copy files that are neither regular files nor

2584 * unexcw.c (fixup_executable): Use posix_fallocate to ensure that
2585 the dumped Emacs is not a sparse file, greatly improving Cygwin
2586 "make bootstrap" performance.

2590 * inotify.c (inotify_callback): Generate an Emacs event for every
2591 incoming inotify event.
2593 2012-12-11 Eli Zaretskii <eliz@gnu.org>
2595 * xdisp.c (handle_face_prop): Fix logic of computing
2596 it->start_of_box_run_p.
2597 (append_space_for_newline): If the glyph row is R2L, reset the
2598 iterator's end_of_box_run_p flag before prepending the space glyph.
2599 (extend_face_to_end_of_line): If the glyph row is R2L, reset the
2600 iterator's start_of_box_run_p flag before prepending the stretch.

2602 (append_stretch_glyph, append_glyphless_glyph): Reverse the
2603 left_box_line_p and right_box_line_p flags of the glyph for R2L
2604 glyph rows. (Bug#13011)

2800 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
2802 Use putenv+unsetenv instead of modifying environ directly (Bug#13070).
2803 * alloc.c (xputenv): New function.
2804 * dbusbind.c (Fdbus_init_bus):
2806 * xterm.c (x_term_init):
2807 Use xputenv instead of setenv or putenv, to detect memory exhaustion.
2808 * editfns.c (initial_tz): Move static var decl up.
2809 (tzvalbuf_in_environ): New static var.
2810 (init_editfns): Initialize these two static vars.
2811 (Fencode_time): Don't assume arbitrary limit on EMACS_INT width.
2812 Save old TZ value on stack, if it's small.
2813 (Fencode_time, set_time_zone_rule): Don't modify 'environ' directly;
2814 instead, use xputenv+unsetenv to set and restore TZ.
2815 (environbuf): Remove static var. All uses removed.
2816 (Fset_time_zone_rule): Do not save TZ and environ;
2817 no longer needed here.
2818 (set_time_zone_rule_tz1, set_time_zone_rule_tz2) [LOCALTIME_CACHE]:
2819 Move to inside set_time_zone_rule; they don't need file scope any more.
2820 (set_time_zone_rule): Maintain the TZ=value string separately.
2821 (syms_of_editfns): Don't initialize initial_tz;
2822 init_editfns now does it.
2823 * emacs.c (dump_tz) [HAVE_TZSET]: Now const.
2824 * lisp.h (xputenv): New decl.
2826 2012-12-08 Fabrice Popineau <fabrice.popineau@gmail.com>
2828 * w32fns.c (emacs_abort): Don't do arithmetics on void pointers.
2830 2012-12-08 Eli Zaretskii <eliz@gnu.org>
2832 * w32.c (unsetenv, sys_putenv): New functions.
2834 2012-12-08 Chong Yidong <cyd@gnu.org>
2836 * editfns.c (Finsert_char): Make the error message more
2837 informative (Bug#12992).
2839 2012-12-08 Paul Eggert <eggert@cs.ucla.edu>
2841 Simplify get_lim_data.
2842 * vm-limit.c (get_lim_data): Combine RLIMIT_AS and RLIMIT_DATA methods.
2843 Remove USG and vlimit methods; no longer used these days.
2844 Add #error catchall just in case.
2846 Assume POSIX 1003.1-1988 or later for signal.h (Bug#13026).
2847 Exceptions: do not assume SIGCONT, SIGSTOP, SIGTSTP, SIGTTIN,
2848 SIGTTOU, SIGUSR1, SIGUSR2, as Microsoft platforms lack these.
2849 * process.c [subprocesses]: Include <c-ctype.h>, <sig2str.h>.
2850 (deleted_pid_list, Fdelete_process, create_process)
2851 (record_child_status_change, handle_child_signal, deliver_child_signal)
2852 (init_process_emacs, syms_of_process):
2853 Assume SIGCHLD is defined.
2854 (parse_signal): Remove. All uses removed.
2855 (abbr_to_signal): New static function.
2856 (Fsignal_process): Use it to convert signal names to ints.
2857 * sysdep.c (sys_suspend) [!DOS_NT]: Use kill (0, ...) rather than
2858 kill (getpgrp (), ...).
2859 (emacs_sigaction_init): Assume SIGCHLD is defined.
2860 (init_signals): Assume SIGALRM, SIGCHLD, SIGHUP, SIGKILL,
2861 SIGPIPE, and SIGQUIT are defined. Do not worry about SIGCLD any more.
2862 * syssignal.h (EMACS_KILLPG): Remove.
2863 All uses replaced by 'kill' with a negative pid.
2864 (SIGCHLD): Remove definition, as we now assume SIGCHLD.
2865 * w32proc.c (sys_kill): Support negative pids compatibly with POSIX.
2867 2012-12-07 Paul Eggert <eggert@cs.ucla.edu>
2869 * sysdep.c (get_child_status): Abort on internal error (Bug#13086).
2870 This will cause a production Emacs to dump core instead of
2873 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
2875 * frame.c (make_frame): Do not set window's buffer to t.
2876 * window.c (Fsplit_window_internal): Likewise. Previously it was
2877 used to indicate that the window is being set up. Now we use
2878 set_window_buffer for all new windows, so the condition in ...
2879 (Fset_window_buffer): ... is always true and can be removed.
2881 2012-12-07 Dmitry Antipov <dmantipov@yandex.ru>
2883 Convenient macro to check whether the buffer is hidden.
2884 * buffer.h (BUFFER_HIDDEN_P): New macro.
2885 * frame.c (make_frame): Use it. Adjust comment.
2886 * buffer.c (candidate_buffer): New function.
2887 (Fother_buffer, other_buffer_safely): Use it.
2889 2012-12-06 Eli Zaretskii <eliz@gnu.org>
2891 * w32proc.c (waitpid): Avoid busy-waiting when called with WNOHANG
2892 if the child process is still running. Instead, exit the wait
2893 loop and return zero. (Bug#13086)
2895 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
2897 * frame.h (x_char_width, x_char_height): Remove prototypes.
2898 * w32term.h (x_char_width, x_char_height): Likewise.
2899 * xfns.c (x_char_width, x_char_height): Remove.
2900 * w32fns.c (x_char_width, x_char_height): Likewise.
2901 * nsfns.c (x_char_width, x_char_height): Likewise.
2902 * frame.c (Fframe_char_width): Use FRAME_COLUMN_WIDTH for
2904 (Fframe_char_height): Likewise with FRAME_LINE_HEIGHT.
2905 * keyboard.c (command_loop_1): Remove prototype.
2906 (command_loop_2, top_level_1): Add static to match prototype.
2908 2012-12-06 Paul Eggert <eggert@cs.ucla.edu>
2910 Fix a recently-introduced delete-process race condition.
2911 * callproc.c, process.h (record_kill_process):
2912 New function, containing part of the old call_process_kill.
2913 (call_process_kill): Use it.
2914 This does not change call_process_kill's behavior.
2915 * process.c (Fdelete_process): Use record_kill_process to fix a
2916 race condition that could cause Emacs to lose track of a child.
2918 2012-12-06 Dmitry Antipov <dmantipov@yandex.ru>
2920 Avoid code duplication between prev_frame and next_frame.
2921 * frame.c (candidate_frame): New function. Add comment.
2922 (prev_frame, next_frame): Use it. Adjust comment.
2924 2012-12-06 Eli Zaretskii <eliz@gnu.org>
2926 * callproc.c (Fcall_process_region) [!HAVE_MKSTEMP]: If mktemp
2927 fails, signal an error instead of continuing with an empty
2929 Encode expanded temp file pattern before passing it to mkstemp or
2932 * fileio.c (file_name_as_directory, directory_file_name) [DOS_NT]:
2933 Encode the file name before passing it to dostounix_filename, in
2934 case it will downcase it (under w32-downcase-file-names).
2937 2012-12-05 Paul Eggert <eggert@cs.ucla.edu>
2939 Minor call-process cleanups.
2940 * callproc.c (Fcall_process): Do record-unwind-protect on MSDOS
2941 at the same time as other platforms, to simplify analysis.
2942 No need for fd0_volatile since we have synch_process_fd.
2943 Avoid needless emacs_close; arg is always negative.
2945 2012-12-04 Andreas Schwab <schwab@linux-m68k.org>
2947 * callproc.c (Fcall_process): Fix specpdl nesting for asynchronous
2950 2012-12-04 Dmitry Antipov <dmantipov@yandex.ru>
2952 * lisp.h (Mouse_HLInfo): Remove set-but-unused mouse_face_image_state
2953 member. Adjust users. Convert mouse_face_past_end, mouse_face_defer
2954 and mouse_face_hidden members to a bitfields.
2955 * frame.h (struct frame): Remove set-but-not-used space_width member.
2956 (FRAME_SPACE_WIDTH): Remove.
2957 * nsterm.m, w32term.c, xterm.c: Adjust users.
2958 * termchar.h (struct tty_display_info): Remove set-but-unused se_is_so
2959 member. Adjust users. Convert term_initted, delete_in_insert_mode,
2960 costs_set, insert_mode, standout_mode, cursor_hidden and flow_control
2961 members to a bitfields.
2963 2012-12-03 Paul Eggert <eggert@cs.ucla.edu>
2965 Don't let call-process be a zombie factory (Bug#12980).
2966 Fixing this bug required some cleanup of the signal-handling code.
2967 As a side effect, this change also fixes a longstanding rare race
2968 condition whereby Emacs could mistakenly kill unrelated processes,
2969 and it fixes a bug where a second C-g does not kill a recalcitrant
2970 synchronous process in GNU/Linux and similar platforms.
2971 The patch should also fix the last vestiges of Bug#9488,
2972 a bug which has mostly been fixed on the trunk by other changes.
2973 * callproc.c, process.h (synch_process_alive, synch_process_death)
2974 (synch_process_termsig, sync_process_retcode):
2975 Remove. All uses removed, to simplify analysis and so that
2976 less consing is done inside critical sections.
2977 * callproc.c (call_process_exited): Remove. All uses replaced
2978 with !synch_process_pid.
2979 * callproc.c (synch_process_pid, synch_process_fd): New static vars.
2980 These take the role of what used to be in unwind-protect arg.
2982 (block_child_signal, unblock_child_signal):
2983 New functions, to avoid races that could kill innocent-victim processes.
2984 (call_process_kill, call_process_cleanup, Fcall_process): Use them.
2985 (call_process_kill): Record killed processes as deleted, so that
2986 zombies do not clutter up the system. Do this inside a critical
2987 section, to avoid a race that would allow the clutter.
2988 (call_process_cleanup): Fix code so that the second C-g works again
2989 on common platforms such as GNU/Linux.
2990 (Fcall_process): Create the child process in a critical section,
2991 to fix a race condition. If creating an asynchronous process,
2992 record it as deleted so that zombies do not clutter up the system.
2993 Do unwind-protect for WINDOWSNT too, as that's simpler in the
2994 light of these changes. Omit unnecessary call to emacs_close
2995 before failure, as the unwind-protect code does that.
2996 * callproc.c (call_process_cleanup):
2997 * w32proc.c (waitpid): Simplify now that synch_process_alive is gone.
2998 * process.c (record_deleted_pid): New function, containing
2999 code refactored out of Fdelete_process.
3000 (Fdelete_process): Use it.
3001 (process_status_retrieved): Remove. All callers changed to use
3002 child_status_change.
3003 (record_child_status_change): Remove, folding its contents into ...
3004 (handle_child_signal): ... this signal handler. Now, this
3005 function is purely a handler for SIGCHLD, and is not called after
3006 a synchronous waitpid returns; the synchronous code is moved to
3007 wait_for_termination. There is no need to worry about reaping
3008 more than one child now.
3009 * sysdep.c (get_child_status, child_status_changed): New functions.
3010 (wait_for_termination): Now takes int * status and bool
3011 interruptible arguments, too. Do not record child status change;
3012 that's now the caller's responsibility. All callers changed.
3013 Reimplement in terms of get_child_status.
3014 (wait_for_termination_1, interruptible_wait_for_termination):
3015 Remove. All callers changed to use wait_for_termination.
3016 * syswait.h: Include <stdbool.h>, for bool.
3017 (record_child_status_change, interruptible_wait_for_termination):
3019 (record_deleted_pid, child_status_changed): New decls.
3020 (wait_for_termination): Adjust to API changes noted above.
3022 * bytecode.c, lisp.h (Qbytecode): Remove.
3023 No longer needed after 2012-11-20 interactive-p changes.
3025 2012-12-03 Eli Zaretskii <eliz@gnu.org>
3027 * xdisp.c (redisplay_window): If the cursor is visible, but inside
3028 the scroll margin, move point outside the margin. (Bug#13055)
3030 2012-12-03 Jan Djärv <jan.h.d@swipnet.se>
3032 * gtkutil.c (my_log_handler): New function.
3033 (xg_set_geometry): Set log handler to my_log_handler (Bug#11177).
3035 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
3037 * lisp.h (modify_region): Rename to...
3038 (modify_region_1): ...new prototype.
3039 * textprop.c (modify_region): Now static. Adjust users.
3040 * insdel.c (modify_region): Rename to...
3041 (modify_region_1): ...new function to work with current buffer.
3042 Adjust comment and users. Use true and false for booleans.
3044 2012-12-03 Dmitry Antipov <dmantipov@yandex.ru>
3046 * alloc.c (free_save_value): New function.
3047 (safe_alloca_unwind): Use it.
3048 * lisp.h (free_save_value): New prototype.
3049 * editfns.c (save_excursion_save): Use Lisp_Misc_Save_Value.
3051 (save_excursion_restore): Adjust to match saved data structure.
3052 Use free_save_value to offload some work from GC. Drop obsolete
3055 2012-12-03 Chong Yidong <cyd@gnu.org>
3057 * fileio.c (Vauto_save_list_file_name): Doc fix.
3059 2012-12-03 Fabrice Popineau <fabrice.popineau@gmail.com>
3061 * w32fns.c: Remove prototype of atof.
3062 (syspage_mask): Make it DWORD_PTR, for compatibility with 64-bit
3064 (file_dialog_callback): Make it UINT_PTR.
3066 * w32common.h (syspage_mask): Declare DWORD_PTR, for compatibility
3069 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
3070 (FILE_ANY_ACCESS, CTL_CODE) [_MSC_VER]: Define only if not already
3073 2012-12-03 Glenn Morris <rgm@gnu.org>
3075 * data.c (Fboundp, Fsymbol_value): Doc fix re lexical-binding.
3077 2012-12-02 Paul Eggert <eggert@cs.ucla.edu>
3079 Fix xpalloc confusion after memory is exhausted.
3080 * alloc.c (xpalloc): Comment fix.
3081 * charset.c (Fdefine_charset_internal): If xpalloc exhausts memory
3082 and signals an error, do not clear charset_table_size, as
3083 charset_table is still valid.
3084 * doprnt.c (evxprintf): Clear *BUF after freeing it.
3086 Use execve to avoid need to munge environ (Bug#13054).
3087 * callproc.c (Fcall_process):
3088 * process.c (create_process):
3089 Don't save and restore environ; no longer needed.
3090 * callproc.c (child_setup):
3091 Use execve, not execvp, to preserve environ.
3093 2012-12-01 Paul Eggert <eggert@cs.ucla.edu>
3095 * xterm.c (x_draw_image_relief): Remove unused locals (Bug#10500).
3097 2012-12-01 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3099 * xterm.c (x_draw_relief_rect, x_draw_image_relief): Fix relief
3100 display for sliced images (Bug#10500).
3102 * w32term.c (w32_draw_relief_rect, x_draw_image_relief): Likewise.
3104 2012-11-30 Juanma Barranquero <lekktu@gmail.com>
3106 * doc.c (Fdocumentation): Re-add handling of function-documentation,
3107 accidentally removed in 2012-11-09T04:10:16Z!monnier@iro.umontreal.ca (bug#13034).
3109 2012-11-29 Dmitry Antipov <dmantipov@yandex.ru>
3111 * xdisp.c (window_outdated): Remove eassert since it hits
3112 some suspicious corner cases (see Bug#13007 and Bug#13012).
3113 (mode_line_update_needed): New function.
3114 (redisplay_internal, redisplay_window): Use it.
3115 (ensure_selected_frame): New function.
3116 (redisplay_internal, unwind_redisplay): Use it.
3117 (redisplay_internal): Move comment about buffer_shared...
3118 (buffer_shared_and_changed): ...near to its real use.
3120 2012-11-29 Paul Eggert <eggert@cs.ucla.edu>
3122 * callproc.c (Fcall_process): Don't misreport vfork failure.
3124 2012-11-28 Paul Eggert <eggert@cs.ucla.edu>
3126 * callproc.c (Fcall_process): Fix vfork portability problems.
3127 Do not assume that fd[0], count, filefd, and save_environ survive
3128 vfork. Fix bug whereby wrong errno value could be reported for
3129 pipe failure. Some minor cleanups, too, as follows. Move buf and
3130 bufsize to the context where they're needed. Change new_argv to
3131 be of type char **, as this is more convenient and avoids casts.
3132 (CALLPROC_BUFFER_SIZE_MIN, CALLPROC_BUFFER_SIZE_MAX):
3133 Now local constants, not macros.
3135 2012-11-18 Kenichi Handa <handa@gnu.org>
3137 * font.c (font_unparse_xlfd): Fix previous change. Keep "const"
3138 for the variable "f".
3140 2012-11-13 Kenichi Handa <handa@gnu.org>
3142 * font.c (font_unparse_xlfd): Exclude special characters from the
3143 generating XLFD name.
3145 2012-11-27 Paul Eggert <eggert@cs.ucla.edu>
3147 Assume POSIX 1003.1-1988 or later for grp.h, pwd.h.

3149 * fileio.c (Fexpand_file_name): Remove no-longer-needed casts.
3151 Assume POSIX 1003.1-1988 or later for errno.h (Bug#12968).

3155 * fileio.c (Fcopy_file): Assume EISDIR is defined.
3156 * gmalloc.c (ENOMEM, EINVAL): Assume they're defined.
3157 * gnutls.c (emacs_gnutls_write): Assume EAGAIN is defined.
3158 * lread.c (readbyte_from_file): Assume EINTR is defined.
3159 * process.c (wait_reading_process_output, send_process) [subprocesses]:
3160 Assume EIO and EAGAIN are defined.
3161 * unexcoff.c (write_segment): Assume EFAULT is defined.
3163 2012-11-27 Eli Zaretskii <eliz@gnu.org>
3165 * fontset.c (Finternal_char_font): Return nil on non-GUI frames.
3168 * xdisp.c (draw_glyphs): Don't draw in mouse face if mouse
3169 highlighting on the frame was cleared. Prevents assertion
3170 violations when repeatedly clicking on the "Top" link of the
3171 "bread-crumbs" in Info buffers.
3173 2012-11-25 Paul Eggert <eggert@cs.ucla.edu>
3175 * sysdep.c (sys_subshell): Don't assume pid_t fits in int.
3177 2012-11-24 Ken Brown <kbrown@cornell.edu>
3179 * keyboard.c (HAVE_MOUSE):
3180 * frame.c (HAVE_MOUSE): Remove, and rewrite code as if HAVE_MOUSE
3181 were always defined.
3183 2012-11-24 Eli Zaretskii <eliz@gnu.org>
3185 * xdisp.c (set_cursor_from_row): Skip step 2 only if point is not
3186 between bpos_covered and bpos_max. This fixes cursor display when
3187 several display strings follow each other.
3189 * .gdbinit (pgx): If the glyph's object is a string, display the
3190 pointer to string data, rather than the value of the string object
3191 itself (which barfs under CHECK_LISP_OBJECT_TYPE).
3193 * indent.c (Fvertical_motion): If the starting position is covered
3194 by a display string, return to one position before that, to avoid
3195 overshooting it inside move_it_to. (Bug#12930)
3197 2012-11-23 Dmitry Antipov <dmantipov@yandex.ru>
3199 * frame.h (struct frame): Remove display_preempted member

3202 * w32menu.c (pending_menu_activation): Remove since not
3204 (set_frame_menubar): Adjust user.
3205 * w32term.h (struct x_output): Drop outdated #if 0 code.
3206 (struct w32_output): Use bitfields for explicit_parent,
3207 asked_for_visible and menubar_active members.
3208 Drop unused pending_menu_activation member.
3209 * xterm.h (struct x_output): Drop outdated #if 0 code.
3210 Use bitfields for explicit_parent, asked_for_visible,
3211 has_been_visible and net_wm_state_hidden_seen members.
3213 2012-11-23 Eli Zaretskii <eliz@gnu.org>
3215 * makefile.w32-in (globals.h, gl-stamp): Use $(SWITCHCHAR) instead
3216 of a literal "/". (Bug#12955)
3217 (gl-stamp): Invoke fc.exe directly, not through cmd.
3219 2012-11-23 Paul Eggert <eggert@cs.ucla.edu>
3221 Assume POSIX 1003.1-1988 or later for dirent.h (Bug#12958).
3222 * dired.c: Assume HAVE_DIRENT_H.
3223 (NAMLEN): Remove, replacing with ...
3224 (dirent_namelen): New function. All uses changed. Use the GNU macro
3225 _D_EXACT_NAMELEN if available, as it's faster than strlen.
3226 (DIRENTRY): Remove, replacing all uses with 'struct dirent'.
3227 (DIRENTRY_NONEMPTY): Remove. All callers now assume it's nonzero.
3228 * makefile.w32-in (DIR_H): Remove. All uses replaced with
3230 ($(BLD)/w32.$(O)): Do not depend on $(SRC)/ndir.h.
3231 * ndir.h: Rename to ../nt/inc/dirent.h.
3232 * sysdep.h (closedir) [!HAVE_CLOSEDIR]: Remove.
3233 Do not include <dirent.h>; no longer needed.
3234 * w32.c: Include <dirent.h> rather than "ndir.h".
3236 2012-11-23 Chong Yidong <cyd@gnu.org>
3238 * xftfont.c (xftfont_open): Remove duplicate assignment.
3240 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
3242 * alloc.c (Fgarbage_collect): Unblock input after clearing
3243 gc_in_progress to avoid note_mouse_highlight glitch with GC.
3244 * frame.h (FRAME_MOUSE_UPDATE): New macro.
3245 * msdos.c (IT_frame_up_to_date): Use it here...
3246 * w32term.c (w32_frame_up_to_date): ...here...
3247 * xterm.c (XTframe_up_to_date): ...and here...
3248 * nsterm.m (ns_frame_up_to_date): ...but not here.
3249 * lisp.h (Mouse_HLInfo): Remove mouse_face_deferred_gc member.
3251 * xdisp.c (message2_nolog, message3_nolog, note_mouse_highlight):
3252 Do not check whether GC is in progress.
3254 2012-11-22 Dmitry Antipov <dmantipov@yandex.ru>
3256 * xdisp.c (window_buffer_changed): New function.
3257 (update_menu_bar, update_tool_bar): Use it to
3258 simplify large 'if' statements.
3259 (redisplay_internal): Generalize commonly used
3260 'tail' and 'frame' local variables.
3262 2012-11-22 Eli Zaretskii <eliz@gnu.org>
3264 * w32.c (getcwd): Fix the 2nd argument type, to prevent conflicts
3265 with Windows system header.
3267 2012-11-21 Paul Eggert <eggert@cs.ucla.edu>
3269 Assume POSIX 1003.1-1988 or later for unistd.h (Bug#12945).
3270 * alloc.c: Assume unistd.h exists.
3271 * fileio.c (Fexpand_file_name) [DOS_NT]: Use getcwd, not getwd.
3272 * sysdep.c (get_current_dir_name): Assume getcwd exists.
3273 (getwd) [USG]: Remove; no longer needed.
3274 (sys_subshell) [DOS_NT]: Use getcwd, not getwd.
3275 * w32.c (getcwd): Rename from getwd, and switch to getcwd's API.
3276 * w32.h (getcwd): Remove decl.
3278 2012-11-21 Stefan Monnier <monnier@iro.umontreal.ca>
3280 * xdisp.c (fast_set_selected_frame): Rename from update_tool_bar_unwind.
3281 Make it set selected_window as well.
3282 (update_tool_bar): Use it.
3284 2012-11-21 Ken Brown <kbrown@cornell.edu>
3286 * emacs.c (main): Set the G_SLICE environment variable for all
3287 Cygwin builds, not just GTK builds. See
3288 https://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00368.html.
3290 2012-11-21 Eli Zaretskii <eliz@gnu.org>
3292 * w32.c (FILE_DEVICE_FILE_SYSTEM, METHOD_BUFFERED)
3293 (FILE_ANY_ACCESS, CTL_CODE, FSCTL_GET_REPARSE_POINT) [_MSC_VER]:
3294 Define for the MSVC compiler.
3296 * w32term.h (EnumSystemLocalesW) [_MSC_VER]: Add a missing semi-colon.
3298 * fileio.c (Fsubstitute_in_file_name, Ffile_name_directory)
3299 (Fexpand_file_name) [DOS_NT]: Pass encoded file name to
3300 dostounix_filename. Prevents crashes down the road, because
3301 dostounix_filename assumes it gets a unibyte string.
3302 Reported by Michel de Ruiter <michel@sentient.nl>, see
3303 http://lists.gnu.org/archive/html/help-emacs-windows/2012-11/msg00017.html
3305 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>

3309 * lread.c (init_obarray): Set `function' fields to Qnil.
3310 * eval.c (Fcommandp): Ignore Qunbound.
3311 (Fautoload, eval_sub, Fapply, Ffuncall, Fmacroexpand):
3312 * data.c (Ffset, Ffboundp, indirect_function, Findirect_function):
3313 Test NILP rather than Qunbound.
3314 (Ffmakunbound): Set to Qnil.
3315 (Fsymbol_function): Never signal an error.
3316 (Finteractive_form): Ignore Qunbound.
3318 2012-11-20 Paul Eggert <eggert@cs.ucla.edu>
3320 * eval.c (interactive_p): Remove no-longer-used decl.
3322 2012-11-20 Dmitry Antipov <dmantipov@yandex.ru>
3324 * xdisp.c (buffer_shared): Adjust comment.
3325 (buffer_shared_and_changed): New function.
3326 (prepare_menu_bars, redisplay_internal): Use it to
3327 decide whether all windows or frames should be updated.
3328 (window_outdated): New function.
3329 (text_outside_line_unchanged_p, redisplay_window): Use it.
3330 (redisplay_internal): Likewise. Fix indentation.
3332 2012-11-20 Stefan Monnier <monnier@iro.umontreal.ca>
3334 * eval.c (Finteractive_p, Fcalled_interactively_p, interactive_p): Remove.
3335 (syms_of_eval): Remove corresponding defsubr.
3336 * bytecode.c (exec_byte_code): `interactive-p' is now a Lisp function.
3338 2012-11-19 Daniel Colascione <dancol@dancol.org>
3340 * w32fns.c (Fx_file_dialog):
3341 (Fx_file_dialog): Accomodate rename of cygwin_convert_path* to
3342 cygwin_convert_file_name*.
3344 * cygw32.c (Fcygwin_convert_path_to_windows, syms_of_cygw32):
3345 Rename cygwin_convert_path* to cygwin_convert_file_name*.
3347 2012-11-18 Paul Eggert <eggert@cs.ucla.edu>
3349 * nsterm.m (ns_select): Send SIGIO only to self, not to process group.
3351 2012-11-18 Eli Zaretskii <eliz@gnu.org>
3353 * w32select.c: Include w32common.h before w32term.h, so that
3354 windows.h gets included before w32term.h uses some of its
3355 features, see below.
3357 * w32term.h (LOCALE_ENUMPROCA, LOCALE_ENUMPROCW) [_MSC_VER]:
3359 (EnumSystemLocalesA, EnumSystemLocalesW) [_MSC_VER]:
3361 (EnumSystemLocales) [_MSC_VER]: Define if undefined. (Bug#12878)
3363 2012-11-18 Jan Djärv <jan.h.d@swipnet.se>
3365 * nsterm.m (hold_event): Set send_appdefined to YES (Bug#12834).
3366 (ns_select): Return at once if events are held (Bug#12834).
3368 2012-11-18 enami tsugutomo <tsugutomo.enami@jp.sony.com>
3370 * unexelf.c (ELFSIZE) [__NetBSD__ && _LP64]: Set to 64.
3371 Needed following 2012-10-20 change. (Bug#12902)
3373 2012-11-18 Juanma Barranquero <lekktu@gmail.com>
3375 * w32proc.c (waitpid): Remove unused label get_result.
3377 2012-11-17 Juanma Barranquero <lekktu@gmail.com>
3379 * makefile.w32-in (SYSWAIT_H): New macro.
3380 ($(BLD)/callproc.$(O), $(BLD)/w32proc.$(O), $(BLD)/process.$(O))
3381 ($(BLD)/sysdep.$(O)): Update dependencies.
3383 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
3385 Assume POSIX 1003.1-1988 or later for fcntl.h (Bug#12881).
3386 * callproc.c (relocate_fd): Assume F_DUPFD.
3387 * emacs.c, term.c (O_RDWR): Remove.
3388 * keyboard.c (tty_read_avail_input): Use O_NONBLOCK rather than
3389 O_NDELAY, since O_NONBLOCK is the standard name for this flag.
3390 * nsterm.m: Assume <fcntl.h> exists.
3391 * process.c (NON_BLOCKING_CONNECT, allocate_pty, create_process)
3392 (create_pty, Fmake_network_process, server_accept_connection)
3393 (wait_reading_process_output, init_process_emacs):
3395 (wait_reading_process_output): Put in a special case for WINDOWSNT
3396 to mimick the older behavior where it had O_NDELAY but not O_NONBLOCK.
3397 It's not clear this is needed, but it's a more-conservative change.
3398 (create_process): Assume FD_CLOEXEC.
3399 (create_process, create_pty): Assume O_NOCTTY.
3400 * sysdep.c (init_sys_modes, reset_sys_modes): Assume F_SETFL.
3401 (reset_sys_modes): Use O_NONBLOCK rather than O_NDELAY.
3402 Omit if not DOS_NT, since F_GETFL is not defined there.
3403 (serial_open): Assume O_NONBLOCK and O_NOCTTY.
3404 * term.c: Include <fcntl.h>, for flags like O_NOCTTY.
3406 (init_tty): Assume O_IGNORE_CTTY is defined to 0 on platforms that
3407 lack it, since gnulib guarantees this.
3408 * w32.c (fcntl): Test for O_NONBLOCK rather than O_NDELAY.
3410 2012-11-17 Eli Zaretskii <eliz@gnu.org>
3412 * w32.c (faccessat): Pretend that directories have the execute bit
3413 set. Emacs expects that, e.g., in files.el:cd-absolute.
3415 * w32proc.c (create_child): Don't clip the PID of the child
3416 process to fit into an Emacs integer, as this is no longer a
3418 (waitpid): Rename from sys_wait. Emulate a Posix 'waitpid' by
3419 reaping only the process specified by PID argument, if that is
3420 positive. Use PID instead of dead_child to know which process to
3421 reap. Wait for the child to die only if WNOHANG is not in
3423 (sys_select): Don't set dead_child.
3425 * sysdep.c (wait_for_termination_1): Remove the WINDOWSNT portion,
3426 as it is no longer needed.
3428 * process.c (waitpid, WUNTRACED) [!WNOHANG]: Remove definitions,
3430 (record_child_status_change): Remove the setting of
3431 record_at_most_one_child for the !WNOHANG case.
3433 2012-11-17 Paul Eggert <eggert@cs.ucla.edu>
3435 Fix problems in ns port found by static checking.
3436 * nsterm.m: Include <pthread.h>, for pthread_mutex_lock etc.
3437 (hold_event, setPosition:portion:whole:): Send SIGIO only to self,
3438 not to process group.
3439 (ns_select): Use emacs_write, not write, as that's more robust
3440 in the presence of signals.
3441 (fd_handler:): Check for read errors.
3443 2012-11-16 Glenn Morris <rgm@gnu.org>
3445 * editfns.c (Fmessage): Mention message-log-max. (Bug#12849)
3447 2012-11-16 Stefan Monnier <monnier@iro.umontreal.ca>
3449 * eval.c (Finteractive_p): Revert lexbind-merge mishap.
3451 2012-11-16 Eli Zaretskii <eliz@gnu.org>
3453 * w32proc.c (timer_loop): Make sure SuspendThread and ResumeThread
3454 use the same value of thread handle.
3455 (start_timer_thread): If the timer thread exited (due to error),
3456 clean up by closing the two handles it used. Duplicate the caller
3457 thread's handle here, so it gets duplicated only once, when
3458 launching the timer thread. Set priority of the timer thread, not
3460 (getitimer): Don't duplicate the caller thread's handle here.
3463 2012-11-16 Jan Djärv <jan.h.d@swipnet.se>
3465 * nsterm.m (hold_event): Send SIGIO to make sure ns_read_socket is
3468 2012-11-16 Paul Eggert <eggert@cs.ucla.edu>
3470 Remove no-longer-used pty_max_bytes variable.
3471 * process.c (pty_max_bytes): Remove; unused.
3472 (send_process): Do not set it.
3474 2012-11-15 Juanma Barranquero <lekktu@gmail.com>
3476 * makefile.w32-in ($(BLD)/dispnew.$(O), $(BLD)/emacs.$(O)):
3477 Update dependencies.
3479 2012-11-15 Paul Eggert <eggert@cs.ucla.edu>
3481 * eval.c (mark_backtrace) [BYTE_MARK_STACK]: Remove stray '*'.
3482 This follows up on the 2012-09-29 patch that removed indirection
3483 for the 'function' field. Reported by Sergey Vinokurov in
3484 <http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00263.html>.
3486 2012-11-14 Eli Zaretskii <eliz@gnu.org>
3488 * w32.c (faccessat): Rename from sys_faccessat. (No need to use a
3489 different name, as the MS runtime does not have such a function,
3490 and probably never will.) All callers changed. Ignore DIRFD
3491 value if PATH is an absolute file name, to match Posix spec
3492 better. If AT_SYMLINK_NOFOLLOW is set in FLAGS, don't resolve
3495 2012-11-14 Dmitry Antipov <dmantipov@yandex.ru>
3497 * xdisp.c (echo_area_display, redisplay_internal):
3498 Omit redundant check whether frame_garbaged is set.
3500 2012-11-14 Paul Eggert <eggert@cs.ucla.edu>
3502 Use faccessat, not access, when checking file permissions (Bug#12632).
3503 This fixes a bug that has been present in Emacs since its creation.
3504 It was reported by Chris Torek in 1983 even before GNU Emacs existed,
3505 which must set some sort of record. (Torek's bug report was against
3506 a predecessor of GNU Emacs, but GNU Emacs happened to have the
3507 same common flaw.) See Torek's Usenet posting
3508 "setuid/setgid programs & Emacs" Article-I.D.: sri-arpa.858
3509 Posted: Fri Apr 8 14:18:56 1983.
3510 * Makefile.in (LIB_EACCESS): New macro.
3512 * callproc.c (init_callproc):
3513 * charset.c (init_charset):
3514 * fileio.c (check_existing, check_executable, check_writable)
3516 * lread.c (openp, load_path_check):
3517 * process.c (allocate_pty):
3519 Use effective UID when checking permissions, not real UID.
3520 * callproc.c (init_callproc):
3521 * charset.c (init_charset):
3522 * lread.c (load_path_check, init_lread):
3523 Test whether directories are accessible, not merely whether they exist.
3524 * conf_post.h (GNULIB_SUPPORT_ONLY_AT_FDCWD): New macro.
3525 * fileio.c (check_existing, check_executable, check_writable)
3527 Use symbolic names instead of integers for the flags, as they're
3529 (check_writable): New arg AMODE. All uses changed.
3530 Set errno on failure.
3531 (Ffile_readable_p): Use faccessat, not stat + open + close.
3532 (Ffile_writable_p): No need to call check_existing + check_writable.
3533 Just call check_writable and then look at errno. This saves a syscall.
3534 dir should never be nil; replace an unnecessary runtime check
3535 with an eassert. When checking the parent directory of a nonexistent
3536 file, check that the directory is searchable as well as writable, as
3537 we can't create files in unsearchable directories.
3538 (file_directory_p): New function, which uses 'stat' on most platforms
3539 but faccessat with D_OK (for efficiency) if WINDOWSNT.
3540 (Ffile_directory_p, Fset_file_times): Use it.
3541 (file_accessible_directory_p): New function, which uses a single
3542 syscall for efficiency.
3543 (Ffile_accessible_directory_p): Use it.
3544 * xrdb.c (file_p): Use file_directory_p.
3545 * lisp.h (file_directory_p, file_accessible_directory_p): New decls.
3546 * lread.c (openp): When opening a file, use fstat rather than
3547 stat, as that avoids a permissions race. When not opening a file,
3548 use file_directory_p rather than stat.
3549 (dir_warning): First arg is now a usage string, not a format.
3550 Use errno. All uses changed.
3551 * nsterm.m (ns_term_init): Remove unnecessary call to file-readable
3552 that merely introduced a race.
3553 * process.c, sysdep.c, term.c: All uses of '#ifdef O_NONBLOCK'
3554 changed to '#if O_NONBLOCK', to accommodate gnulib O_* style,
3555 and similarly for the other O_* flags.
3556 * w32.c (sys_faccessat): Rename from sys_access and switch to
3557 faccessat's API. All uses changed.
3558 * xrdb.c: Do not include <sys/stat.h>; no longer needed.
3559 (magic_db): Rename from magic_file_p.
3560 (magic_db, search_magic_path): Return an XrmDatabase rather than a
3561 char *, so that we don't have to test for file existence
3562 separately from opening the file for reading. This removes a race
3563 fixes a permission-checking problem, and simplifies the code.
3565 (file_p): Remove; no longer needed.
3567 2012-11-13 Dmitry Antipov <dmantipov@yandex.ru>
3569 Omit glyphs initialization at startup.
3570 * dispnew.c (glyphs_initialized_initially_p): Remove.
3571 (adjust_frame_glyphs_initially): Likewise. Adjust users.
3572 (Fredraw_frame): Move actual code from here...
3573 (redraw_frame): ...to here. Add eassert. Adjust comment.
3574 (Fredraw_display): Use redraw_frame.
3575 * xdisp.c (clear_garbaged_frames): Likewise.
3577 2012-11-13 Eli Zaretskii <eliz@gnu.org>
3579 * xdisp.c (decode_mode_spec): Limit the value of WIDTH argument
3580 passed to pint2str and pint2hrstr to be at most the size of the
3581 frame's decode_mode_spec_buffer. This avoids crashes with very
3582 large values of FIELD_WIDTH argument to decode_mode_spec.
3585 2012-11-13 Paul Eggert <eggert@cs.ucla.edu>
3587 Fix a race with verify-visited-file-modtime (Bug#12863).
3588 Since at least 1991 Emacs has ignored an mtime difference of no
3589 more than one second, but my guess is that this was to work around
3590 file system bugs that were fixed long ago. Since the race is
3591 causing problems now, let's remove that code.
3592 * fileio.c (Fverify_visited_file_modtime): Do not accept a file
3593 whose time stamp is off by no more than a second. Insist that the
3594 file time stamps match exactly.
3596 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
3598 * frame.h (struct frame): Convert external_tool_bar member to
3599 1-bit unsigned bitfield.
3600 * termhooks.h (struct terminal): Remove mouse_moved member since
3601 all users are long dead. Adjust comment on mouse_position_hook.
3603 2012-11-12 Dmitry Antipov <dmantipov@yandex.ru>
3605 Simplify by using FOR_EACH_FRAME here and there.
3606 * frame.c (next_frame, prev_frame, other_visible_frames)
3607 (delete_frame, visible-frame-list): Use FOR_EACH_FRAME.
3608 * w32term.c (x_window_to_scroll_bar): Likewise.
3609 * window.c (window_list): Likewise.
3610 * xdisp.c (x_consider_frame_title): Likewise.
3611 * xfaces.c ( Fdisplay_supports_face_attributes_p): Likewise.
3612 * xfns.c (x_window_to_frame, x_any_window_to_frame)
3613 (x_menubar_window_to_frame, x_top_window_to_frame): Likewise.
3614 * xmenu.c (menubar_id_to_frame): Likewise.
3615 * xselect.c (frame_for_x_selection): Likewise.
3616 * xterm.c (x_frame_of_widget, x_window_to_scroll_bar)
3617 (x_window_to_menu_bar): Likewise.
3618 * w32fns.c (x_window_to_frame): Likewise. Adjust comment.
3620 2012-11-12 Paul Eggert <eggert@cs.ucla.edu>
3622 * data.c (Qdefalias_fset_function): Now static.
3624 Another tweak to vectorlike_header change.
3625 * alloc.c (struct Lisp_Vectorlike_Free, NEXT_IN_FREE_LIST):
3626 Remove, and replace all uses with ...
3627 (next_in_free_list, set_next_in_free_list):
3628 New functions, which respect C's aliasing rules better.
3630 2012-11-11 Paul Eggert <eggert@cs.ucla.edu>
3632 * window.c (list4i): Rename from 'quad'. All uses changed.
3633 Needed because <sys/types.h> defines 'quad' on Solaris 10.
3635 2012-11-11 Juanma Barranquero <lekktu@gmail.com>
3637 * xdisp.c (start_hourglass) [HAVE_NTGUI]: Add block to silence
3638 warning about mixing declarations and code in ISO C90.
3640 2012-11-10 Martin Rudalics <rudalics@gmx.at>
3642 * window.c (Fsplit_window_internal): Set combination limit of
3643 new parent window to t iff Vwindow_combination_limit is t;
3644 fixing a regression introduced with the change from 2012-09-22.
3645 (Fset_window_combination_limit): Fix doc-string.
3647 2012-11-10 Eli Zaretskii <eliz@gnu.org>
3649 * xdisp.c (try_scrolling): Fix correction of aggressive-scroll
3650 amount when the scroll margins are too large. When scrolling
3651 backwards in the buffer, give up if cannot reach point or the
3652 scroll margin within a reasonable number of screen lines.
3653 Fixes point position in window under scroll-up/down-aggressively when
3654 point is positioned many lines beyond the window top/bottom.
3657 * ralloc.c (relinquish): If real_morecore fails to return memory
3658 to the system, don't crash; instead, leave the last heap
3659 unchanged and return. (Bug#12774)
3661 2012-11-09 Stefan Monnier <monnier@iro.umontreal.ca>
3663 * lisp.h (AUTOLOADP): New macro.
3664 * eval.c (Fautoload): Don't attach to loadhist, call Fdefalias instead.
3665 * data.c (Ffset): Remove special ad-advice-info handling.
3666 (Fdefalias): Handle autoload definitions and new Qdefalias_fset_function.
3668 (Finteractive_form): Simplify.
3669 (Fquo): Don't insist on having at least 2 arguments.
3670 (Qdefalias_fset_function): New var.
3672 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
3674 * image.c (xpm_make_color_table_h): Change to hashtest_equal.
3676 * nsfont.m (Qcondensed, Qexpanded): New variables.
3677 (ns_descriptor_to_entity): Restore Qcondensed, Qexpanded setting.
3678 (syms_of_nsfont): Defsym Qcondensed, Qexpanded.
3680 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
3682 Fix recently introduced crash on MS-Windows (Bug#12839).
3683 * w32term.h (struct scroll_bar): Use convenient header.
3684 (SCROLL_BAR_VEC_SIZE): Remove.
3685 * w32term.c (x_scroll_bar_create): Use VECSIZE.
3687 2012-11-09 Dmitry Antipov <dmantipov@yandex.ru>
3689 Tweak last vectorlike_header change.
3690 * alloc.c (struct Lisp_Vectorlike_Free): Special type to represent
3691 vectorlike object on the free list. This is introduced to avoid
3692 some (but not all) pointer casting and aliasing problems, see
3693 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00105.html.
3694 * .gdbinit (pvectype, pvecsize): New commands to examine vectorlike
3696 (xvectype, xvecsize): Use them to examine Lisp_Object values.
3698 2012-11-09 Jan Djärv <jan.h.d@swipnet.se>
3700 * nsfont.m (ns_descriptor_to_entity): Qcondensed and Qexpanded has
3701 been removed, so remove them here also.

3723 * lisp.h (sxhash_combine): New inline function, with the contents
3724 of the old SXHASH_COMBINE.
3725 * profiler.c (hashfn_profiler): Use it, instead of having a
3726 special hash function containing a comparison that always yields 1.
3728 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3730 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic)
3731 (Qultra_condensed, Qextra_condensed, Qcondensed, Qsemi_condensed)
3732 (Qsemi_expanded, Qextra_expanded, Qexpanded, Qultra_expanded):
3735 2012-11-08 Jan Djärv <jan.h.d@swipnet.se>
3737 * image.c (xpm_make_color_table_h): Fix compiler error because
3738 make_hash_table changed.
3740 2012-11-08 Thomas Kappler <tkappler@gmail.com> (tiny change)
3742 * nsfont.m (ns_findfonts): Handle empty matchingDescs (Bug#11541).
3744 2012-11-08 Stefan Monnier <monnier@iro.umontreal.ca>
3746 Use ad-hoc comparison function for the profiler's hash-tables.
3747 * profiler.c (Qprofiler_backtrace_equal, hashtest_profiler): New vars.
3748 (make_log): Use them.
3749 (handle_profiler_signal): Don't inhibit quit any longer since we don't
3750 call Fequal any more.

3759 (hashfn_equal, hashfn_user_defined): Adjust to new calling convention.
3760 (hash_lookup, hash_remove_from_table): Move assertion checking of
3761 hashfn result here. Check hash-equality before calling cmpfn.

3773 * w32fns.c (modifier_set): Fix handling of Scroll Lock when the
3774 value of w32-scroll-lock-modifier is neither nil nor one of the
3775 known key modifiers. (Bug#12806)
3777 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
3779 Shrink struct vectorlike_header to the only size field.
3780 * lisp.h (enum pvec_type): Avoid explicit enum member values.
3782 (enum More_Lisp_Bits): Change PSEUDOVECTOR_SIZE_BITS and
3783 PVEC_TYPE_MASK to arrange new bitfield in the vector header.
3784 (PSEUDOVECTOR_REST_BITS, PSEUDOVECTOR_REST_MASK): New members.
3785 (PSEUDOVECTOR_AREA_BITS): New member used to extract subtype
3786 information from the vector header. Adjust comment.

3801 the vectors with the memory footprint more than VBLOOCK_BYTES_MAX.
3802 (large_vectors): Change type to struct large_vector.
3803 (allocate_vector_from_block): Simplify.
3804 (PSEUDOVECTOR_NBYTES): Replace with...
3805 (vector_nbytes): ...new function. Adjust users.

3807 (allocate_vectorlike): Likewise.
3808 (allocate_pseudovector): Change type of 3rd arg to enum pvec_type.
3809 Add easserts. Adjust XSETPVECTYPESIZE usage.
3810 (allocate_buffer): Use BUFFER_PVEC_INIT.
3811 (live_vector_p): Adjust to match large vector.
3812 * buffer.c (init_buffer_once): Use BUFFER_PVEC_INIT.
3813 * buffer.h (struct buffer): Add next member.
3814 (BUFFER_LISP_SIZE, BUFFER_REST_SIZE, BUFFER_PVEC_INIT):

3824 2012-11-08 Dmitry Antipov <dmantipov@yandex.ru>
3826 * keyboard.c (event_to_kboard): Do not dereference
3827 frame_or_window field of SELECTION_REQUEST_EVENT
3828 and SELECTION_CLEAR_EVENT events (Bug#12814).
3829 * xterm.h (struct selection_input_event): Adjust comment.
3831 2012-11-07 Eli Zaretskii <eliz@gnu.org>
3833 * w32fns.c (modifier_set): Don't report modifiers from toggle key,
3834 such as Scroll Lock, if the respective keys are treated as
3835 function keys, not as modifiers. This avoids destroying non-ASCII
3836 keyboard input when Scroll Lock is toggled ON. (Bug#12806)
3838 2012-11-07 Dmitry Antipov <dmantipov@yandex.ru>
3840 * xfns.c (Fx_wm_set_size_hint): Use check_x_frame. Adjust docstring.
3842 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
3844 Restore some duplicate definitions (Bug#12814).
3845 This undoes part of the 2012-11-03 changes. Some people build
3846 with plain -g rather than with -g3, and they need the duplicate
3847 definitions for .gdbinit to work; see <http://bugs.gnu.org/12814#26>.
3848 * lisp.h (GCTYPEBITS, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK):
3849 Define as macros, as well as as enums or as constants.
3851 2012-11-06 Jan Djärv <jan.h.d@swipnet.se>
3853 * nsterm.m (convert_ns_to_X_keysym, keyDown:): Add NSNumericPadKeyMask
3854 to keypad keys (Bug#12816).
3856 2012-11-06 Paul Eggert <eggert@cs.ucla.edu>
3858 Minor adjustments of recently-changed frame functions.
3859 * buffer.c (Fbuffer_list): Omit CHECK_FRAME, since arg is already
3860 known to be a frame (we're in the FRAMEP branch).
3861 * lisp.h (Qframep): Remove decl. frame.h declares this.
3862 * window.c (quad): Args are of type EMACS_INT, not ptrdiff_t,
3863 since they're meant for Lisp fixnum values.
3865 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3867 * window.c (Fwindow_combination_limit): Revert to the only
3868 required argument and adjust docstring as suggested in
3869 http://lists.gnu.org/archive/html/emacs-diffs/2012-11/msg01082.html
3870 by Martin Rudalics <rudalics@gmx.at>.
3872 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3874 Widely used frame validity and checking functions.
3875 * frame.h (decode_live_frame, decode_any_frame): Add prototypes.
3876 * frame.c (decode_live_frame, decode_any_frame): New functions.
3877 (delete_frame, Fredirect_frame_focus, Fframe_parameters)
3878 (Fframe_parameter, Fframe_char_height, Fframe_char_width)
3879 (Fframe_pixel_height, Fframe_pixel_width, Ftool_bar_pixel_width)

3883 (Fset_frame_height, Fset_frame_width): Use decode_live_frame.
3884 (Fframe_focus): Likewise. Allow zero number of arguments.
3886 (frame_buffer_list, frame_buffer_predicate): Remove.
3887 * lisp.h (frame_buffer_predicate): Remove prototype.
3888 * buffer.c (Fother_buffer): Use decode_any_frame.
3889 * xdisp.c (Ftool_bar_lines_needed): Likewise.
3890 * xfaces.c (Fcolor_gray_p, Fcolor_supported_p): Likewise.
3891 * font.c (Ffont_face_attributes, Ffont_family_list, Fopen_font)
3892 (Fclose_font, Ffont_info): Use decode_live_frame.
3893 * fontset.c (check_fontset_name): Likewise.
3894 * terminal.c (Fframe_terminal): Likewise.
3895 * w32fns.c (check_x_frame): Likewise.
3896 * window.c (Fminibuffer_window, Fwindow_at)
3897 (Fcurrent_window_configuration): Likewise.
3898 (Frun_window_configuration_change_hook, Fwindow_resize_apply):
3899 Likewise. Allow zero number of arguments. Adjust docstring.
3900 * dispnew.c (Fredraw_frame): Likewise.
3901 * xfaces.c (frame_or_selected_frame): Remove.
3902 (Fx_list_fonts, Finternal_get_lisp_face_attribute, Fface_font)
3903 (Finternal_lisp_face_equal_p, Finternal_lisp_face_empty_p)
3904 (Fframe_face_alist): Use decode_live_frame.
3905 * xfns.c (check_x_frame): Likewise.
3907 2012-11-06 Dmitry Antipov <dmantipov@yandex.ru>
3909 * window.c (quad): New function.
3910 (Fwindow_edges, Fwindow_pixel_edges, Fwindow_inside_edges)
3911 (Fwindow_absolute_pixel_edges, Fwindow_inside_absolute_pixel_edges)
3912 (Fwindow_inside_pixel_edges, Fpos_visible_in_window_p)
3913 (Fwindow_line_height): Use it.
3914 (Fwindow_fringes): Use list3.
3915 (Fwindow_scroll_bars): Use list4.
3916 (Fwindow_frame, Fwindow_top_child, Fwindow_left_child)
3917 (Fwindow_combination_limit): Allow zero number of arguments.
3919 2012-11-05 Eli Zaretskii <eliz@gnu.org>
3921 * makefile.w32-in ($(BLD)/w32fns.$(O)): Depend on $(NT_INC)/unistd.h.
3923 * w32fns.c: Include unistd.h, to avoid compiler warnings on Cygwin.
3924 (emacs_abort) [CYGWIN]: Don't call _open_osfhandle; instead, use
3925 file descriptor 2 for standard error. (Bug#12805)
3927 2012-11-05 Chong Yidong <cyd@gnu.org>
3929 * process.c (wait_reading_process_output): Revert previous change.
3931 2012-11-05 Paul Eggert <eggert@cs.ucla.edu>
3933 Assume at least POSIX.1-1988 for getpgrp, setpgid, setsid (Bug#12800).
3934 This removes code that has been obsolete since around 1990.
3935 * callproc.c (Fcall_process):
3937 * process.c (create_process):
3938 * term.c (dissociate_if_controlling_tty):
3939 Assume setsid exists.
3940 * callproc.c (child_setup): Assume setpgid exists and behaves as
3941 per POSIX.1-1988 or later.
3942 * conf_post.h (setpgid) [!HAVE_SETPGID]: Remove.
3943 * emacs.c (shut_down_emacs):
3944 * sysdep.c (sys_suspend, init_foreground_group):
3945 Assume getpgrp behaves as per POSIX.1-1998 or later.
3946 * msdos.c (setpgrp): Remove.
3947 (tcgetpgrp, setpgid, setsid): New functions.
3948 * systty.h (EMACS_GETPGRP): Remove. All callers now use getpgrp.
3949 * term.c (no_controlling_tty): Remove; unused.
3950 * w32proc.c (setpgrp): Remove.
3951 (setsid, tcgetpgrp): New functions.
3953 Simplify by assuming __fpending.
3954 * dispnew.c: Include <fpending.h>, not <stdio_ext.h>.
3955 (update_frame_1): Use __fpending, not PENDING_OUTPUT_COUNT.
3956 Do not assume that __fpending's result fits in int.
3958 2012-11-04 Paul Eggert <eggert@cs.ucla.edu>
3960 Remove EMACS_OUTQSIZE+sleep hack.
3961 * dispnew.c (update_frame_1): Remove hack for terminals slower
3962 than 2400 bps, which throttled Emacs by having it sleep.
3963 This code hasn't worked since at least 2007, when the multi-tty stuff
3964 was added, and anyway those old terminals are long dead.
3965 * systty.h (EMACS_OUTQSIZE): Remove; unused. The macro isn't used even
3966 without the dispnew.c change, as dispnew.c doesn't include systty.h.
3968 Fix data-loss with --version (Bug#9574).
3969 * emacs.c (close_output_streams): Use strerror, not emacs_strerror,
3970 as we can't assume that emacs_strerror is initialized, and strerror
3971 is good enough here.
3972 (main): Invoke atexit earlier, to catch earlier instances of
3973 sending data to stdout and exiting, e.g., "emacs --version >/dev/full".
3975 2012-11-04 Michael Marchionna <tralfaz@pacbell.net>
3977 * nsterm.m: Add NSClearLineFunctionKey and keypad keys (Bug#8680).
3978 (keyDown): Remap keypad keys to X11 virtual key codes.
3980 2012-11-03 Paul Eggert <eggert@cs.ucla.edu>
3982 Fix data-loss with --batch (Bug#9574).
3983 * emacs.c: Include <close-stream.h>.
3984 (close_output_streams): New function.
3985 (main): Pass it to atexit, so that Emacs closes stdout and stderr
3986 and handles errors appropriately.
3987 (Fkill_emacs): Don't worry about flushing, as close_output_stream
3990 Fix a race condition that causes Emacs to mess up glib (Bug#8855).
3991 The symptom is a diagnostic "GLib-WARNING **: In call to
3992 g_spawn_sync(), exit status of a child process was requested but
3993 SIGCHLD action was set to SIG_IGN and ECHILD was received by
3994 waitpid(), so exit status can't be returned." The diagnostic
3995 is partly wrong, as the SIGCHLD action is not set to SIG_IGN.
3996 The real bug is a race condition between Emacs and glib: Emacs
3997 does a waitpid (-1, ...) and reaps glib's subprocess by mistake,
3998 so that glib can't find it. Work around the bug by invoking
3999 waitpid only on subprocesses that Emacs itself creates.
4000 * process.c (create_process, record_child_status_change):
4001 Don't use special value -1 in pid field, as the caller now must
4002 know the pid rather than having the callee infer it.
4003 The inference was sometimes incorrect anyway, due to another race.
4004 (create_process): Set new 'alive' member if child is created.
4005 (process_status_retrieved): New function.
4006 (record_child_status_change): Use it.
4007 Accept negative 1st argument, which means to wait for the
4008 processes that Emacs already knows about. Move special-case code
4009 for DOS_NT (which lacks WNOHANG) here, from caller. Keep track of
4010 processes that have already been waited for, by testing and
4011 clearing new 'alive' member.
4012 (CAN_HANDLE_MULTIPLE_CHILDREN): Remove, as record_child_status_change
4013 now does this internally.
4014 (handle_child_signal): Let record_child_status_change do all
4015 the work, since we do not want to reap all exited child processes,
4016 only the child processes that Emacs itself created.
4017 * process.h (Lisp_Process): New boolean member 'alive'.
4019 Omit duplicate definitions no longer needed with gcc -g3.
4020 * lisp.h (GCTYPEBITS, GCALIGNMENT, ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG)
4021 (VALMASK, MOST_POSITIVE_FIXNUM, MOST_NEGATIVE_FIXNUM):
4022 Define only as macros. There's no longer any need to also define
4023 these symbols as enums or as constants, since we now assume
4024 gcc -g3 when debugging.
4026 2012-11-03 Eli Zaretskii <eliz@gnu.org>
4028 * lisp.mk: Adjust comments to the fact that term/internal is now
4029 loaded from loadup.el.
4031 * msdos.c (msdos_abort): Rename from emacs_abort, and make static.
4032 (msdos_fatal_signal): New function.
4033 (XMenuActivate): Adjust the call to kbd_buffer_events_waiting to
4036 * conf_post.h (_GL_EXECINFO_INLINE) [MSDOS]: Define to "inline"
4037 for GCC versions before 4.
4038 (emacs_raise): Define to call msdos_fatal_signal.
4040 * xdisp.c (init_from_display_pos): Fix initialization of the bidi
4041 iterator when starting in the middle of a display or overlay
4044 2012-11-03 Chong Yidong <cyd@gnu.org>
4046 * process.c (wait_reading_process_output): Clean up the last
4049 2012-11-03 Jim Paris <jim@jtan.com> (tiny change)
4051 * process.c (wait_reading_process_output): Avoid a race condition
4052 with SIGIO delivery (Bug#11536).
4054 2012-11-03 Chong Yidong <cyd@gnu.org>
4056 * buffer.c (cursor_type): Untabify docstring.
4058 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
4060 * frame.h (struct frame): Drop can_have_scroll_bars member
4061 which is meaningless for a long time. Adjust comments.
4062 (FRAME_CAN_HAVE_SCROLL_BARS): Remove.
4063 * frame.c, nsfns.m, term.c, w32fns.c, xfns.c: Adjust users.
4065 2012-11-03 Dmitry Antipov <dmantipov@yandex.ru>
4067 * window.c (decode_next_window_args): Update window arg after
4068 calling decode_live_window and so fix crash reported at
4069 http://lists.gnu.org/archive/html/emacs-devel/2012-11/msg00035.html
4070 by Juanma Barranquero <lekktu@gmail.com>.
4071 (Fwindow_body_width, Fwindow_body_height): Simplify a bit.
4072 * font.c (Ffont_at): Likewise.
4074 2012-11-01 Jan Djärv <jan.h.d@swipnet.se>
4076 * widget.c (resize_cb): New function.
4077 (EmacsFrameRealize): Add resize_cb as event handler (Bug#12733).
4078 (EmacsFrameResize): Check if all is up to date before changing frame
4081 2012-11-02 Eli Zaretskii <eliz@gnu.org>
4083 Implement backtrace output for fatal errors on MS-Windows.
4084 * w32fns.c (CaptureStackBackTrace_proc): New typedef.
4085 (BACKTRACE_LIMIT_MAX): New macro.
4086 (w32_backtrace): New function.
4087 (emacs_abort): Use w32_backtrace when the user chooses not to
4088 attach a debugger. Update the text of the abort dialog.
4090 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
4092 Window-related stuff cleanup here and there.
4093 * dispnew.c (Finternal_show_cursor, Finternal_show_cursor_p):
4094 Use decode_any_window.
4095 * fringe.c (Ffringe_bitmaps_at_pos): Likewise.
4096 * xdisp.c (Fformat_mode_line): Likewise.
4097 * font.c (Ffont_at): Use decode_live_window.
4098 * indent.c (Fcompute_motion, Fvertical_motion): Likewise.
4099 * window.c (decode_next_window_args): Likewise.
4100 (decode_any_window): Remove static.
4101 * window.h (decode_any_window): Add prototype.
4102 * lisp.h (CHECK_VALID_WINDOW, CHECK_LIVE_WINDOW): Move from here...
4103 * window.h: ...to here, redefine via WINDOW_VALID_P and WINDOW_LIVE_P,
4106 2012-11-02 Dmitry Antipov <dmantipov@yandex.ru>
4108 Remove pad from struct input_event.
4109 * termhooks.h (struct input_event): Remove padding field.
4111 * keyboard.c (event_to_kboard): Simplify because frame_or_window
4112 member is never cons for a long time. Adjust comment.
4113 (mark_kboards): Adjust because SELECTION_REQUEST_EVENT and
4114 SELECTION_CLEAR_EVENT has no Lisp_Objects to mark. Add comment.
4115 * xterm.c (handle_one_xevent): Do not initialize frame_or_window
4116 field of SELECTION_REQUEST_EVENT and SELECTION_CLEAR_EVENT.
4118 2012-11-01 Eli Zaretskii <eliz@gnu.org>
4120 * w32proc.c (getpgrp, setpgid): New functions. (Bug#12776)
4122 2012-10-31 Paul Eggert <eggert@cs.ucla.edu>
4124 Fix crash when using Emacs as commit editor for git (Bug#12697).
4125 * callproc.c (setpgrp): Remove macro, as we now use setpgid
4126 and it is configured in conf_post.h.
4127 (Fcall_process): Don't invoke both setsid and setpgid; the former
4128 is enough, if it exists.
4129 * callproc.c (Fcall_process, child_setup):
4130 * process.c (create_process): Use setpgid.
4131 * conf_post.h (setpgid) [!HAVE_SETPGID]: New macro, which substitutes
4133 * dispnew.c (init_display): Initialize the foreground group
4134 if we are running a tty display.
4135 * emacs.c (main): Do not worry about setpgrp; init_display does it now.
4136 * lisp.h (init_foreground_group): New decl.
4137 * sysdep.c (inherited_pgroup): New static var.
4138 (init_foreground_group, tcsetpgrp_without_stopping)
4139 (narrow_foreground_group, widen_foreground_group): New functions.
4140 (init_sys_modes): Narrow foreground group.

4143 2012-10-31 Michael Albinus <michael.albinus@gmx.de>
4145 * dbusbind.c: Fix cut'n'waste error. Use HAVE_DBUS_VALIDATE_INTERFACE.
4147 2012-10-31 Martin Rudalics <rudalics@gmx.at>
4149 * minibuf.c (read_minibuf): Restore current buffer since
4150 choose_minibuf_frame calling Fset_frame_selected_window may
4151 change it (Bug#12766).
4153 2012-10-30 Jan Djärv <jan.h.d@swipnet.se>
4155 * frame.c (Fframe_pixel_height): Fix documentation (Bug#12733).
4157 2012-10-30 Kenichi Handa <handa@gnu.org>
4159 * font.c (Ffont_at): If WINDOW is specified and it is not
4160 displaying the current buffer, signal an error.
4162 2012-10-29 Daniel Colascione <dancol@dancol.org>
4164 * cygw32.h, cygw32.c (Qutf_16le, from_unicode, to_unicode):
4165 In preparation for fixing bug#12739, move these functions from
4168 * coding.h, coding.c: ... to here, and compile them only when
4169 WINDOWSNT or CYGWIN. Moving these functions out of cygw32 proper
4170 lets us write cygw32-agnostic code for the HAVE_NTGUI case.
4172 2012-10-28 Eli Zaretskii <eliz@gnu.org>
4174 * w32proc.c (TIMER_TICKS_PER_SEC): New macro.
4175 (timer_loop, getitimer, setitimer): Use it instead of
4176 CLOCKS_PER_SEC, which is no longer pertinent, since we don't use
4178 (w32_get_timer_time): Use 10*TIMER_TICKS_PER_SEC instead of a
4181 2012-10-28 Jan Djärv <jan.h.d@swipnet.se>

4185 (last_appdefined_event): Remove.
4186 (ns_select): Initialize t from last_appdefined_event_data instead
4187 of [last_appdefined_event data1].
4188 (sendEvent:): Save [theEvent data1] to last_appdefined_event_data,
4189 remove last_appdefined_event (Bug#12698).
4191 2012-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
4193 * frame.c (x_set_font): Catch internal error.
4195 2012-10-27 Eli Zaretskii <eliz@gnu.org>
4197 Avoid overflow in w32 implementation of interval timers.
4198 When possible, for ITIMER_PROF count only times the main thread
4200 * w32proc.c <struct itimer_data>: 'expire' and 'reload' are now
4201 'volatile ULONGLONG' types. All the other data which was
4202 previously clock_t is now ULONGLONG. 'terminate' is 'volatile int'.
4203 (GetThreadTimes_Proc): New typedef.
4204 (w32_get_timer_time): New function, returns a suitable time value
4206 (timer_loop): Enter critical section when accessing ULONGLONG
4207 values of the itimer_data struct, as these accesses are no longer
4208 atomic. Call 'w32_get_timer_time' instead of 'clock'.
4209 Remove unused variable.
4210 (init_timers): Initialize s_pfn_Get_Thread_Times.
4211 (start_timer_thread): Don't assign itimer->caller_thread here.
4212 (getitimer): Assign itimer->caller_thread here.
4213 (setitimer): Always call getitimer to get the value of ticks_now.

4218 * w32fns.c (w32_wnd_proc) <WM_MOUSEMOVE>: Don't enable tracking of
4219 mouse movement events if the menu bar is active. This avoids
4220 producing a busy "hour-glass" cursor by Windows if the mouse
4221 pointer is positioned over a tooltip shown for some menu item.
4223 2012-10-25 Paul Eggert <eggert@cs.ucla.edu>
4225 Don't assume process IDs fit in int.
4226 * emacs.c (shut_down_emacs) [!DOS_NT]:
4227 * sysdep.c (sys_suspend) [SIGTSTP && !MSDOS]:
4228 * term.c (dissociate_if_controlling_tty) [!DOS_NT]:
4229 Use pid_t, not int, to store process IDs, as 'int'
4230 is not wide enough on a few platforms (e.g., AIX and IRIX).
4232 2012-10-23 Kenichi Handa <handa@gnu.org>
4234 The following change is to make face-font-rescale-alist work
4235 correctly for non-ASCII fonts.
4237 * font.c (font_open_entity): Don't handle Vface_font_rescale_alist.
4238 (font_open_for_lface): Handle Vface_font_rescale_alist.

4242 * xfaces.c (Vfont_list_limit): Move unused variable to faces.el.
4244 2012-10-21 Jan Djärv <jan.h.d@swipnet.se>

4253 2012-10-21 Glenn Morris <rgm@gnu.org>
4255 * lisp.mk (lisp): Add cp51932.el and eucjp-ms.el.
4257 2012-10-20 Paul Eggert <eggert@cs.ucla.edu>
4259 Port to OpenBSD 5.1.
4260 * frame.c (Fmouse_position, Fmouse_pixel_position):
4261 * xdisp.c (produce_stretch_glyph):
4262 Declare local vars only when they're needed.
4263 This is clearer and avoids a warning on OpenBSD about unused vars.

4265 This is safer, and avoids OpenBSD warnings about unused vars.
4266 * keyboard.c (record_menu_key): Remove unnecessary decl.
4267 (poll_timer): Define only if POLL_FOR_INPUT is defined.
4268 * unexelf.c (ELFSIZE) [!ElfW]: Do not define if already defined,
4269 as our definition clashes with OpenBSD's.
4270 * xfaces.c (load_face_colors, check_lface_attrs)
4271 (get_lface_attributes_no_remap, get_lface_attributes)
4272 (lface_fully_specified_p, x_supports_face_attributes_p)
4273 (tty_supports_face_attributes_p, face_fontset, realize_face)
4274 (realize_x_face, realize_tty_face):
4275 Declare parameters to be Lisp_Object[LFACE_VECTOR_SIZE], not
4276 merely Lisp_Object *. This is more informative and avoids
4277 a warning on OpenBSD about accessing beyond an object's size.
4279 2012-10-20 Chong Yidong <cyd@gnu.org>
4281 * lread.c (Fload): Doc fix (Bug#12592).

4307 * alloc.c (NSTATICS): Increase from 0x650 to 0x1000
4308 (staticpro): If we run out of staticpro slots, die with an
4309 informative error instead of just calling emacs_abort.
4311 2012-10-18 Martin Rudalics <rudalics@gmx.at>
4313 Fix two flaws reported by Dmitry Antipov.

4571 the same pointer-to-int (now pointer-to-boolean) &input_pending,

4573 input_pending. All callers changed.
4574 * keyboard.h (struct kboard): Use unsigned : 1 for boolean member
4575 immediate_echo. Use ptrdiff_t for echo_after_prompt, since it's

4615 2012-10-09 Eli Zaretskii <eliz@gnu.org>
4617 * w32fns.c (w32_last_error): Change the return value to DWORD, to
4618 match what GetLastError returns. Explain why the function is
4621 * frame.c (delete_frame): Rename local variable 'tooltip_frame' to
4622 'is_tooltip_frame', to avoid confusion with its global namesake.
4624 2012-10-08 Daniel Colascione <dancol@dancol.org>
4626 * xdisp.c (start_hourglass): Call w32_note_current_window when
4627 HAVE_NTGUI, not just WINDOWSNT, resolving a problem in the cygw32
4628 build that caused Emacs to display the hourglass cursor forever.
4630 * w32fns.c (Fx_display_color_cells): Instead of using NCOLORS,
4631 which is broken under remote desktop, calculate the number of
4632 colors available for a display based on the display's number of
4633 planes and number of bits per pixel per plane. (bug#10397).
4635 2012-10-08 Jan Djärv <jan.h.d@swipnet.se>
4637 * nsfont.m (Vfonts_in_cache): New variable.
4638 (nsfont_open): Use unsignedLongLongValue for cache in case wide ints
4639 are used. Add cached fonts to Vfonts_in_cache.
4640 (syms_of_nsfont): Initialize and staticpro Vfonts_in_cache.
4642 2012-10-08 Juanma Barranquero <lekktu@gmail.com>
4644 * makefile.w32-in (LOCAL_FLAGS): Don't define HAVE_NTGUI, it's now
4646 (FONT_H): Define after FRAME_H.
4647 ($(BLD)/emacs.$(O), $(BLD)/process.$(O), $(BLD)/w32heap.$(O)):
4648 Update dependencies.
4650 * w32term.c: Remove leftover declaration of keyboard_codepage.
4652 2012-10-08 Eli Zaretskii <eliz@gnu.org>
4654 * makefile.w32-in (FONT_H): Add $(FRAME_H).
4655 (W32TERM_H): Add $(ATIMER_H) and $(FRAME_H).
4656 ($(BLD)/emacs.$(O), $(BLD)/w32console.$(O)): Update dependencies.
4657 (GLOBAL_SOURCES): Add cygw32.c.
4658 ($(BLD)/unexw32.$(O)):
4660 ($(BLD)/w32console.$(O)):
4661 ($(BLD)/w32fns.$(O)):
4662 ($(BLD)/w32heap.$(O)):
4663 ($(BLD)/w32menu.$(O)):
4664 ($(BLD)/w32proc.$(O)): Add w32common.h.
4666 * w32fns.c (w32_color_map_lookup, x_to_w32_color): Argument is now
4668 (x_to_w32_color): Don't modify the argument, modify a copy instead.
4670 2012-10-08 Daniel Colascione <dancol@dancol.org>
4672 * w32term.h (WM_EMACS_BRINGTOTOP, WM_EMACS_INPUT_READY)
4673 (WM_EMACS_END): Change WM_EMACS_BRINGTOTOP from 22 to 21 to close
4674 accidental message numbering hole. Change other messages to
4677 * w32select.h (HAVE_W32SELECT): Remove.
4679 * w32select.c, w32proc.c, w32menu.c, w32console.c, w32.c: Include
4680 w32common.h instead of w32heap.h.
4682 * w32heap.h (ROUND_UP, ROUND_DOWN, get_page_size)
4683 (get_allocation_unit, get_processor_type, get_w32_major_version)
4684 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
4685 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
4686 (OS_NT, os_subtype, cache_system_info): Move declarations to
4689 * w32heap.c: Include w32common.h.
4690 (sysinfo_cache, syspage_mask, osinfo_cache, w32_major_version)
4691 (w32_minor_version, w32_build_number, w32_subtype):
4692 Remove duplicate definitions.
4694 * w32fns.c: Include w32common.h; include w32heap.h only in
4697 (Fx_file_dialog): Clarify comment on GetOpenFileName structure.
4698 Use `report_file_error' instead of `error' in order to better
4699 inform users of what went wrong. Increase NTGUI_UNICODE file
4700 dialog box file name length to 32k, the maximum allowed by the NT
4703 * w32common.h: New file.
4704 (ROUND_UP, ROUND_DOWN, get_page_size)
4705 (get_allocation_unit, get_processor_type, get_w32_major_version)
4706 (get_w32_minor_version, sysinfo_cache, osinfo_cache)
4707 (w32_major_version, w32_minor_version, w32_build_number, OS_9X)
4708 (OS_NT, os_subtype, cache_system_info): Move here.
4710 * unexw32.c, unexcw.c: Include w32common.h.
4712 * emacs.c (main): Use (defined (WINDOWSNT) || defined
4713 HAVE_NTGUI) instead of removed HAVE_W32SELECT to decide whether
4714 to call syms_of_w32select.
4716 * cygw32.h: Remove obsolete EXFUN declarations.
4718 * cygw32.c (Qutf_16_le): Rename to Qutf_16le.
4720 * Makefile.in (SOME_MACHINE_OBJECTS): Reverse accidental removal
4721 of w32inevt.o from SOME_MACHINE_OBJECTS.
4723 2012-10-08 Daniel Colascione <dancol@dancol.org>
4725 * image.c: Permanent fix for JPEG compilation issue --- limit
4726 jpeglib `boolean' redefinition to Cygwin builds.
4728 2012-10-08 Eli Zaretskii <eliz@gnu.org>
4730 * image.c (CHECK_LIB_AVAILABLE): Remove, no longer used.
4732 * emacs.c (DAEMON_MUST_EXEC) [HAVE_NTGUI]: Define this only on
4735 2012-10-08 Daniel Colascione <dancol@dancol.org>
4737 * xfaces.c, xdisp.c, window.c, w32xfns.c, w32term.h, w32term.c,
4738 w32select.h w32select.c, w32proc.c, w32menu.c, w32inevt.c,
4739 w32help.c, w32font.c, w32font.c, w32fns.c, w32console.c, w32.h,
4740 w32.c, unexw32.c, termhooks.h, process.c, menu.c, keyboard.h,
4741 keyboard.c, image.c, frame.h, frame.c, fontset.c, font.h, font.c,
4742 emacs.c, dispextern.h, cygw32.h, cygw32.c, conf_post.h,
4743 Makefile.in: use HAVE_NTGUI for W32 GUI and WINDOWSNT for the
4744 operating system. defined(HAVE_NTGUI) && !defined(WINDOWSNT) is
4745 now a supported configuration.
4747 * Makefile.in: consolidate image variables into LIBIMAGE; add
4748 W32_OBJ and W32_LIBS. Compile new files.
4751 (_DebPrint) declare tracing facility for W32 debugging. We need
4752 to unify tracing later.
4754 (NTGUI_UNICODE) Define when compiling for Cygwin to allow the
4755 unconditional use of W32 Unicode functions. Cygwin runs only on
4756 100% Unicode operating systems.
4758 * cygw32.c: New file. Define Cygwin-specific facilities.
4759 (Fcygwin_convert_path_to_windows)
4760 (Fcygwin_convert_path_from_windows): New user functions for
4761 accessing Cygwin path-munging routines.
4763 * cygw32.h: New file.
4764 (WCSDATA, to_unicode, from_unicode): Define facilities for storing
4765 UTF-16LE strings temporarily inside non-Lisp-visible string
4768 (w32_strerror): Just what it says on the tin.
4770 * emacs.c: Make the NS fork-then-exec code for daemon-launching
4771 also run for Cygwin; both systems have the same problem with using
4772 GUI facilities in a forked child. Also call syms_of_cygw32,
4773 syms_of_w32select in correct places.
4775 (DAEMON_MUST_EXEC): new macro defined to signal that a platform
4776 needs fork-then-exec for daemon launching.
4778 * font.h: Include frame.h.
4780 * image.c: Use the image library cache machinery only when we're
4781 compiling for native WINDOWSNT; Cygwin can use shared libraries
4782 like any other Unixlike system.
4784 * keyboard.c: Clarify a comment regarding the input loop.
4786 * menu.c: When NTGUI_UNICODE is defined, use Unicode menu
4787 functions directly instead of trying to detect at runtime that our
4788 host operating system supports them. We make this change for two
4789 reasons: Cygwin lacks support for the multibyte character
4790 conversion functions used by the legacy menu code, and Cygwin
4791 never needs to rely on non-Unicode APIs.
4793 * unexw32.c (hinst): Declare extern.
4795 * w32.c: Change header order;
4796 (w32_strerror): Move to w32fns.c because we need it for
4797 non-WINDOWSNT builds.
4799 * w32.h: Add #error macro to make sure we don't include w32.h for
4800 Cygwin builds. Remove w32select declarations.
4802 * w32console.c (w32_sys_ring_bell, Fset_message_beep): Move to
4803 w32fns.c. w32console.c is WINDOWSNT-only.
4805 * w32fns.c: Include cygw32.h or w32.h depending on CYGWIN; more
4806 NTGUI_UNICODE tweaks. (See above.) Change _snprintf to the more
4808 (faked_key, sysinfo_cache, osinfo_cahce, syspage_mask)
4809 (w32_major_version, w32_minor_version, w32_build_number)
4810 (os_subtype, sound_type): Define here
4811 (w32_defined_color): Make color parameter const for consistency
4812 with other _defined_color functions.
4813 (w32_createwindow): Unconditionally call w32_init_class instead of
4814 doing so only when hprevinst is non-NULL. Plumbing hprevinst
4815 through the code is complex and unnecessary because class
4816 registration is practically free.
4817 (w32_name_of_message): New EMACSDEBUG-only function.
4818 (Fset_message_beep): Move here
4819 (Fx_open_connection): Require that the display name for Windows be
4820 "w32" for consistency, emacsclient disambiguation, and maybe, one
4821 day, multi-window-system support.
4822 (file_dialog_callback): NTGUI_UNICODE changes; encode and decode
4823 Cygwin files for W32 GUI facilities, since these clearly don't
4824 expect Cygwin names.
4825 (_DebPrint): Define.
4826 (w32_strerror, w32_console_toggle_lock_key, w32_kbd_mods_to_emacs)
4827 (w32_kbd_patch_key, w32_sys_ring_bell): Move here.
4828 (Ssystem_move_file_to_trash): Define only for native WINDOWSNT.
4829 (w32_last_error): Remove.
4831 * w32font.c: Define _strlwr to strlwr for non-WINDOWSNT builds.
4833 * w32heap.c (syspage_mask): Declare here.
4834 (cache_system_info): Remove.
4836 * w32inevt.c (faked_key): Define globally, not statically.
4837 (w32_kbd_mods_to_emacs, w32_kbd_patch_key, faked_key)
4838 (w32_console_toggle_lock_key): Move to w32fns.c.
4840 * w32menu.c: Include setjmp.h. NTGUI_UNICODE changes throughout.
4842 * w32proc.c (_DebPrint): Move to w32fns.c.
4843 * w32select.c: Include string.h, stdio.h for Cygwin.
4844 * w32select.h: New File.
4846 * w32term.c: Include io.h for non-CYGWIN builds; needed for
4848 (w32_message_fd): New variable. Under Cygwin, holds the file
4849 descriptor the system used to tell us about pending thread
4852 (w32_init_term): Remove incorrect calls to fcntl and init_sigio
4853 that prevented compilation under non-WINDOWSNT systems.
4855 (w32_initialize): Open /dev/windows and assign it to
4856 w32_message_fd. Provide w32 feature.
4858 * w32term.h: Include frame.h, atimer.h. Declare various frame functions.
4859 (WM_EMACS_INPUT_READY): add.
4860 (prepend_msg, w32_message_fd): Declare globally.
4863 (keyboard_handle): Use only when WINDOWSNT.
4864 (notify_msg_ready): New function. Posts a message to the main
4865 thread's message queue under CYGWIN, which wakes up the main
4866 thread from select(2) by making the /dev/windows file descriptor
4867 ready. Under WINDOWSNT, it sets an event the same way the old
4870 (post, prepend_msg): Actually call notify_msg_ready instead of
4871 setting the input event directly.
4873 2012-10-07 Eli Zaretskii <eliz@gnu.org>
4875 * ralloc.c (relinquish): If a heap is ready to be relinquished,
4876 but it still has blocs in it, don't return it to the system,
4877 instead of aborting. (Bug#12402)
4879 2012-10-07 Jan Djärv <jan.h.d@swipnet.se>
4881 * nsterm.m (ns_dumpglyphs_image): Only draw slice of image (Bug#12506).
4883 * nsterm.m (ns_update_auto_hide_menu_bar): Remove defintion of
4884 MAC_OS_X_VERSION_10_6.
4885 (syms_of_nsterm): Remove comment about Panther and above for
4887 * nsterm.h (MAC_OS_X_VERSION_10_3, onTiger): Remove.
4888 (EmacsApp): Remove check for >= MAC_OS_X_VERSION_10_4.
4889 (struct nsfont_info): Remove check for >= MAC_OS_X_VERSION_10_3.
4891 * nsselect.m (ns_string_from_pasteboard): Remove check for >=
4892 MAC_OS_X_VERSION_10_4.
4894 * nsmenu.m (fillWithWidgetValue:): Remove code for <
4895 MAC_OS_X_VERSION_10_2.
4897 * nsimage.m (setPixmapData, getPixelAtX, setAlphaAtX): Remove onTiger.
4899 * nsfns.m (Fns_list_services): Remove comment and check for OSX < 10.4.
4900 (ns_do_applescript): Remove check for >= MAC_OS_X_VERSION_10_4.
4902 * nsterm.m (ns_in_resize): Remove (Bug#12479).
4903 (ns_resize_handle_rect, mouseDown, mouseUp, mouseDragged): Remove.
4904 (ns_clear_frame, sendEvent, windowDidResize, drawRect:):
4905 Remove ns_in_resize check.
4906 (ns_clear_frame_area): Remove resize handle code.
4908 * nsfns.m (ns_in_resize): Remove.
4909 (x_set_icon_name, ns_set_name, ns_set_name_as_filename):
4910 Remove ns_in_resize check.
4912 2012-10-07 Paul Eggert <eggert@cs.ucla.edu>
4914 Improve sys_siglist detection.
4915 * sysdep.c (sys_siglist, init_signals): Use _sys_siglist if it's
4916 defined as a macro, as is done in Solaris.
4917 (sys_siglist_entries): New macro.
4918 (save_strsignal): Use it.
4919 * syssignal.h (safe_strsignal): Now ATTRIBUTE_CONST, to pacify
4920 GCC 4.7.2 on Fedora 17 with the fixed sys_siglist detection.
4922 2012-10-06 Jan Djärv <jan.h.d@swipnet.se>
4924 * nsfns.m (Fx_create_frame): Call x_default_parameter with
4925 fullscreen/Fullscreen.
4927 * nsterm.h (EmacsView): Rename tbar_height to tibar_height.
4928 tobar_height is new.
4930 * nsterm.m (x_make_frame_visible): Check for fullscreen.
4931 (ns_fullscreen_hook): Activate old style fullscreen with a timer.
4932 (ns_term_init): Set activateIgnoringOtherApps if old style fullscreen.
4933 (windowDidResize:): Check for correct window if old style fullscreen.
4934 Capitalize word in comment. Remove incorrect comment.
4935 (initFrameFromEmacs:): tbar_height renamed tibar_height.
4936 (windowDidEnterFullScreen:): Toggle toolbar for fullscreen to fix
4937 error in drawing background.
4938 (toggleFullScreen:): Remove comment. Rearrange calls.
4939 Set toolbar values to zero, save old height in tobar_height.
4940 Restore tool bar height when leaving fullscreen.
4941 (canBecomeMainWindow): New function.
4943 2012-10-06 Paul Eggert <eggert@cs.ucla.edu>
4945 * keyboard.c (read_char): Remove unnecessary 'volatile's and label.
4947 2012-10-05 Eli Zaretskii <eliz@gnu.org>
4949 * w32proc.c (stop_timer_thread): Fix declaration of 'err'.
4951 * w32.c (utime): Open the file with FILE_FLAG_BACKUP_SEMANTICS, so
4952 that time stamps of directories could also be changed.
4953 Don't request the too broad GENERIC_WRITE, only the more restrictive
4954 FILE_WRITE_ATTRIBUTES access rights.
4956 * fileio.c (Fset_file_times): Special-case ignoring errors for
4957 directories only on MSDOS, not on MS-Windows.
4959 2012-10-05 Ikumi Keita <ikumi@ikumi.que.jp> (tiny change)
4961 * minibuf.c (Fcompleting_read): Doc fix. (Bug#12555)
4963 2012-10-04 Eli Zaretskii <eliz@gnu.org>
4965 * w32.c (utime): Test for INVALID_HANDLE_VALUE, not for NULL, to
4966 see whether CreateFile failed.
4968 2012-10-04 Paul Eggert <eggert@cs.ucla.edu>
4970 * profiler.c (handle_profiler_signal): Inhibit pending signals too,
4971 to avoid similar races.
4972 * keyboard.c (pending_signals): Now bool, not int.
4974 Port timers to OpenBSD, plus check for timer failures.
4975 OpenBSD problem reported by Han Boetes.
4976 * profiler.c (setup_cpu_timer): Check for failure of timer_settime
4978 (Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
4979 * syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
4980 like OpenBSD, which has timer_settime but does not declare it.
4981 OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
4982 whether to use itimerspec-related primitives. All uses of
4983 HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
4985 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
4987 * profiler.c (handle_profiler_signal): Fix a malloc race
4988 that caused Emacs to hang on Fedora 17 when profiling Lisp.
4990 2012-10-02 Jan Djärv <jan.h.d@swipnet.se>
4992 * nsterm.m (windowDidEnterFullScreen): Remove fprintf.
4994 2012-10-02 Eli Zaretskii <eliz@gnu.org>
4996 * w32proc.c (sys_wait): Declare 'signame' 'const char *', to be
4997 consistent with the change in return value of 'safe_strsignal'.
4999 2012-10-02 Paul Eggert <eggert@cs.ucla.edu>
5001 Prefer plain 'static' to 'static inline' (Bug#12541).
5002 * bidi.c (bidi_get_type, bidi_check_type, bidi_get_category)
5003 (bidi_set_sor_type, bidi_push_embedding_level)
5004 (bidi_pop_embedding_level, bidi_remember_char, bidi_copy_it)
5005 (bidi_cache_reset, bidi_cache_shrink, bidi_cache_fetch_state)
5006 (bidi_cache_search, bidi_cache_ensure_space)
5007 (bidi_cache_iterator_state, bidi_cache_find)
5008 (bidi_peek_at_next_level, bidi_set_paragraph_end)
5009 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
5010 (bidi_explicit_dir_char, bidi_resolve_neutral_1):
5011 Now 'static', not 'static inline'.
5013 Count overruns when profiling; change units to ns.
5014 * profiler.c (handle_profiler_signal): Count sampling intervals, not ms.
5015 Give extra weight to samples after overruns, to attempt to count
5016 the time more accurately.
5017 (setup_cpu_timer): Change sampling interval units from ms to ns, since
5018 the underlying primitives nominally do ns.
5019 (Fprofiler_cpu_start): Document the change. Mention that
5020 the sampling intervals are only approximate.
5022 2012-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
5024 * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.
5026 * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
5027 case for the special 0 coding-system.
5029 * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.
5030 (Fmake_overlay): Remove redundant tests.
5031 (fix_start_end_in_overlays): Remove redundant recentering.
5033 2012-10-02 Juanma Barranquero <lekktu@gmail.com>
5035 * makefile.w32-in ($(BLD)/alloc.$(O), $(BLD)/gmalloc.$(O)):
5036 Update dependencies.
5038 2012-10-01 Paul Eggert <eggert@cs.ucla.edu>
5040 Fix a malloc race condition involving strsignal.
5041 A signal can arrive in the middle of a malloc, and Emacs's signal
5042 handler can invoke strsignal, which can invoke malloc, which is
5043 not portable. This race condition bug makes Emacs hang on GNU/Linux.
5044 Fix it by altering the signal handler so that it does not invoke
5046 * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
5047 * process.c (status_message): Use const pointer, in case strsignal
5048 is #defined to safe_strsignal.
5049 * sysdep.c (sys_siglist, init_signals): Always define and
5050 initialize a substitute sys_siglist if the system does not define
5051 one, even if HAVE_STRSIGNAL.
5052 (safe_strsignal): Rename from strsignal. Always define,
5053 using sys_siglist. Return a const pointer.
5054 * syssignal.h (safe_strsignal): New decl.
5055 (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.
5057 2012-10-01 Eli Zaretskii <eliz@gnu.org>
5059 * w32proc.c (timer_loop): Fix code that waits for timer
5060 expiration, to avoid high CPU usage.
5062 2012-10-01 Stefan Monnier <monnier@iro.umontreal.ca>
5064 * fns.c (check_hash_table, get_key_arg, maybe_resize_hash_table)
5065 (sweep_weak_table): Remove redundant prototypes.
5067 2012-10-01 Fabrice Popineau <fabrice.popineau@gmail.com>
5069 * emacs.c: Move the inclusion of TERM_HEADER after including
5070 windows.h on WINDOWSNT. This avoids compilation problems with
5073 2012-10-01 Eli Zaretskii <eliz@gnu.org>
5075 * unexw32.c (OFFSET_TO_RVA, RVA_TO_OFFSET)
5076 (RVA_TO_SECTION_OFFSET): Encode all macro arguments in parentheses.
5077 (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
5078 as the previous version used 'void *'.
5080 * ralloc.c (ROUNDUP): Fix last change.
5081 (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
5084 * w32proc.c <disable_itimers>: New static flag.
5085 (init_timers): Initialize it to zero, after creating the critical
5086 sections used by the timer threads.
5087 (term_timers): Set to 1 before deleting the critical sections.
5088 (getitimer, setitimer): If disable_itimers is non-zero, return an
5089 error indication without doing anything. Reported by Fabrice
5090 Popineau <fabrice.popineau@supelec.fr> as part of bug#12544.
5091 (alarm) [HAVE_SETITIMER]: Be more conformant to the expected
5093 [!HAVE_SETITIMER]: Behave as the previous version that didn't
5096 * emacs.c (shut_down_emacs) [WINDOWSNT]: Move the call to
5097 term_ntproc after all the other bookkeeping, to get timers working
5098 as long as possible.

5102 * xdisp.c (syms_of_xdisp): Default message-log-max to 1000, not 100.
5103 Suggested by Juri Linkov in
5104 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00821.html>.
5106 Prefer plain 'static' to 'static inline' (Bug#12541).
5107 With static functions, modern compilers inline pretty well by
5108 themselves; advice from programmers often hurts as much as it helps.
5109 On my host (x86-64, Fedora 17, GCC 4.7.2, default 'configure'),
5110 this change shrinks the text size of the Emacs executable by 1.1%
5111 without affecting CPU significantly in my benchmark.

5194 Revert the FOLLOW-SYMLINKS change for file-attributes.
5195 Doing it right would require several changes to Tramp, and there's
5196 not enough time to get that tested before the freeze today.
5197 * dired.c (directory_files_internal, Ffile_attributes):
5200 * frame.c (x_report_frame_params): Port better to wider ints.

5404 All uses changed to store the new value.
5405 (handle_profiler_signal): Rename from sigprof_handler_1,
5406 for consistency with other handlers. Do not check whether
5407 cpu_log is a hash-table if garbage collecting, since it
5408 doesn't matter in that case.

5410 for consistency with other handlers.
5411 (setup_cpu_timer): New function, with much of what used to be in

5413 Prefer timer_settime if available, and prefer
5414 thread cputime clocks, then process cputime clocks, then
5415 monotonic clocks, to the old realtime clock. Use make_timeval
5416 to round more-correctly when falling back to setitimer.
5417 (Fprofiler_cpu_start): Use it.
5418 (Fprofiler_cpu_stop): Prefer timer_settime if available.
5419 Don't assume that passing NULL as the 2nd argument of setitimer
5420 is the same as passing a pointer to all-zero storage.
5421 Ignore SIGPROF afterwards.
5422 (malloc_probe): Saturate at MOST_POSITIVE_FIXNUM.
5423 * sysdep.c (emacs_sigaction_init): Also mask out SIGPROF in
5424 non-fatal signal handlers. Ignore SIGPROF on startup.
5425 * syssignal.h (PROFILER_CPU_SUPPORT): Define this macro here, not
5426 in profiler.c, since sysdep.c now uses it.
5428 * sysdep.c (handle_fatal_signal): Bump backtrace size to 40.

5484 * charset.c (decode_char): Use maybe_unify_char, not MAYBE_UNIFY_CHAR.
5485 Since this stuff is now private to charset.c, there's no need for
5486 a public macro and no need to inline by hand.

5524 (set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.
5525 (init_atimer) [SIGEV_SIGNAL]: Initialize them.
5527 2012-09-25 Eli Zaretskii <eliz@gnu.org>
5529 * coding.c (CHAR_STRING_ADVANCE_NO_UNIFY): Make it an alias of
5530 CHAR_STRING_ADVANCE.
5531 (STRING_CHAR_ADVANCE_NO_UNIFY): Make it an alias of
5532 STRING_CHAR_ADVANCE.
5534 2012-09-25 Juanma Barranquero <lekktu@gmail.com>
5536 Move Vlibrary_cache to emacs.c and reset before dumping.
5538 * lisp.h (reset_image_types): Declare.
5539 [WINDOWSNT] (Vlibrary_cache): Declare.
5541 * image.c (reset_image_types): New function.
5543 * emacs.c [WINDOWSNT] (Vlibrary_cache): Move from w32.c.
5544 (syms_of_emacs) [WINDOWSNT] <Vlibrary_cache>: Initialize and staticpro.
5545 (Fdump_emacs): Reset Vlibrary_cache and image_types.
5547 * w32.c (Vlibrary_cache): Do not define; moved to emacs.c
5548 (globals_of_w32) <Vlibrary_cache>: Do not initialize.
5550 * w32.h (Vlibrary_cache): Do not declare.
5552 2012-09-25 Eli Zaretskii <eliz@gnu.org>
5554 * w32proc.c (sys_signal): Handle all signals defined by the
5555 MS-Windows runtime, not just SIGCHLD. Actually install the signal
5556 handlers for signals supported by Windows. Don't override
5557 term_ntproc as the handler for SIGABRT.
5558 (sigaction): Rewrite to call sys_signal instead of duplicating its
5560 (sys_kill): Improve commentary.
5562 * w32.c (term_ntproc): Accept (and ignore) one argument, for
5563 consistency with a signature of a signal handler. All callers
5565 (init_ntproc): Accept an argument DUMPING. If dumping, don't
5566 install term_ntproc as a signal handler for SIGABRT, as that
5567 should be done by the dumped Emacs.
5569 * w32.h (init_ntproc, term_ntproc): Adjust prototypes.
5571 * w32select.c (term_w32select): Protect against repeated
5572 invocation by setting clipboard_owner to NULL after calling
5575 * emacs.c (shut_down_emacs, main): Adapt the calls to init_ntproc
5576 and term_ntproc to their modified signatures.
5578 * character.c (char_string, string_char): Remove calls to
5579 MAYBE_UNIFY_CHAR. See the discussion starting at
5580 http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00433.html
5583 2012-09-25 Chong Yidong <cyd@gnu.org>
5585 * xdisp.c (mode_line_inverse_video): Delete obsolete variable.
5587 2012-09-24 Stefan Monnier <monnier@iro.umontreal.ca>
5589 * bytecode.c (exec_byte_code): Signal an error instead of aborting,
5590 when encountering an unknown bytecode.
5592 2012-09-24 Paul Eggert <eggert@cs.ucla.edu>
5594 image.c, indent.c: Use bool for booleans.
5595 * dispextern.h (struct image_type): Members valid_p, load, init
5596 now return bool, not int. All uses changed.
5597 * image.c: Omit unnecessary static decls.
5598 (x_create_bitmap_mask, x_build_heuristic_mask):
5599 Return void, not int, since callers don't care about the return value.

5628 Use bool for booleans.
5630 2012-09-24 Chong Yidong <cyd@gnu.org>
5632 * chartab.c (Fset_char_table_default): Obsolete function removed.
5634 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5636 Move pid_t related decls out of lisp.h.
5637 * lisp.h, syswait.h (record_child_status_change, wait_for_termination)
5638 (interruptible_wait_for_termination):
5639 Move these decls from lisp.h to syswait.h, since they use pid_t.
5640 Needed on FreeBSD; see Herbert J. Skuhra in
5641 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00571.html>.
5642 * callproc.c: Include syswait.h.

5660 * nsmenu.m, w32menu.c, xmenu.c (set_frame_menubar):
5661 * xfns.c (Fx_show_tip) [USE_GTK]:
5662 Use bool for boolean.
5663 * gtkutil.c (xg_update_frame_menubar):
5664 * xmenu.c (update_frame_menubar):
5665 Return void, not int, since caller ignores return value.
5666 * gtkutil.c (xg_change_toolbar_position):
5669 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
5671 * makefile.w32-in (BLOCKINPUT_H): Remove.

5688 2012-09-23 Eli Zaretskii <eliz@gnu.org>
5690 * .gdbinit: Set breakpoint on terminate_due_to_signal, not on
5691 fatal_error_backtrace.
5693 * w32proc.c (sys_kill): Undo last change: don't do anything when
5694 invoked to deliver SIGABRT to our own process. This is now
5695 handled by emacs_raise.
5697 2012-09-23 Juanma Barranquero <lekktu@gmail.com>
5699 * w32term.c (w32_read_socket): Remove leftover reference to
5700 interrupt_input_pending.
5702 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5704 Do not use SA_NODEFER.
5705 Problem reported by Dani Moncayo in
5706 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00557.html>.
5708 * sysdep.c (emacs_abort): Do not reset signal handler.
5709 * emacs.c (terminate_due_to_signal): Reset signal handler here.
5710 * sysdep.c (init_signals): Do not use SA_NODEFER. It wasn't
5711 wanted even on POSIXish hosts, and it doesn't work on Windows.
5713 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
5715 * xterm.c (x_term_init): Call fixup_locale before and after calling
5716 gtk_init (Bug#12392).
5718 2012-09-23 Chong Yidong <cyd@gnu.org>
5720 * w32.c (w32_delayed_load): Remove LIBRARIES argument; always use
5721 Vdynamic_library_alist.
5723 * gnutls.c (init_gnutls_functions): Caller changed; remove arg.
5724 (Fgnutls_available_p): Caller changed.
5726 * xml.c (init_libxml2_functions, Flibxml_parse_html_region)
5727 (Flibxml_parse_xml_region): Likewise.
5729 * dispextern.h (struct image_type): Remove arg from init function.
5731 * image.c (Finit_image_library, lookup_image_type)
5732 (define_image_type): Remove now-unneeded second arg.
5733 (init_xpm_functions, init_png_functions, init_jpeg_functions)
5734 (init_tiff_functions, init_gif_functions, init_svg_functions):
5735 Arglist and w32_delayed_load calling convention changed.
5736 (gs_type): Remove init_gs_functions; there is no such function.
5737 (valid_image_p, make_image): Fix caller to lookup_image_type.
5739 2012-09-23 Paul Eggert <eggert@cs.ucla.edu>
5741 Simplify and avoid signal-handling races (Bug#12471).
5743 * sysdep.c (emacs_abort) [HAVE_NTGUI]:
5744 Avoid recursive loop if there's a fatal error in the function itself.
5745 * atimer.c (pending_atimers):
5746 * blockinput.h: Don't include "atimer.h"; no longer needed.
5747 (interrupt_input_pending): Remove. All uses removed.
5748 pending_signals now counts both atimers and ordinary interrupts.
5749 This is less racy than having three separate pending-signal flags.
5750 (block_input, unblock_input, totally_unblock_input, unblock_input_to)
5752 Rename from their upper-case counterparts BLOCK_INPUT,
5753 UNBLOCK_INPUT, TOTALLY_UNBLOCK_INPUT, UNBLOCK_INPUT_TO,
5754 INPUT_BLOCKED_P, and turn into functions. All uses changed.
5755 This makes it easier to access volatile variables more accurately.
5756 (BLOCK_INPUT_RESIGNAL): Remove. All uses replaced by unblock_input ().
5757 (input_blocked_p): Prefer this to 'interrupt_input_blocked', as
5758 that's more reliable if the code is buggy and sets
5759 interrupt_input_blocked to a negative value. All uses changed.
5760 * atimer.c (deliver_alarm_signal):
5761 Remove. No need to deliver this to the parent; any thread can
5762 handle this signal now. All uses replaced by underlying handler.
5763 * atimer.c (turn_on_atimers):
5764 * dispnew.c (handle_window_change_signal):
5765 * emacs.c (handle_danger_signal):
5766 * keyboard.c (kbd_buffer_get_event):
5767 Don't reestablish signal handler; not needed with sigaction.
5768 * blockinput.h (UNBLOCK_INPUT_TO, TOTALLY_UNBLOCK_INPUT)
5770 Rework to avoid unnecessary accesses to volatile variables.
5771 (UNBLOCK_INPUT_TO): Now a function.
5772 (totally_unblock_input, unblock_input): New decls.
5773 * data.c (handle_arith_signal, deliver_arith_signal): Move to sysdep.c
5774 (init_data): Remove. Necessary stuff now done in init_signal.
5775 * emacs.c, xdisp.c: Include "atimer.h", since we invoke atimer functions.
5776 * emacs.c (handle_fatal_signal, deliver_fatal_signal): Move to sysdep.c.
5777 (fatal_error_code): Remove; no longer needed.
5778 (terminate_due_to_signal): Rename from fatal_error_backtrace, since
5779 it doesn't always backtrace. All uses changed. No need to reset
5780 signal to default, since sigaction and/or die does that for us now.
5781 Use emacs_raise (FOO), not kill (getpid (), FOO).
5782 (main): Check more-accurately whether we're dumping.
5783 Move fatal-error setup to sysdep.c
5784 * floatfns.c: Do not include "syssignal.h"; no longer needed.
5785 * gtkutil.c (xg_get_file_name, xg_get_font):
5786 Remove no-longer-needed signal-mask manipulation.
5787 * keyboard.c, process.c (POLL_FOR_INPUT):
5788 Don't depend on USE_ASYNC_EVENTS, a symbol that is never defined.
5789 * keyboard.c (read_avail_input): Remove.
5790 All uses replaced by gobble_input.
5791 (Ftop_level): Use TOTALLY_UNBLOCK_INPUT rather than open code.
5792 (kbd_buffer_store_event_hold, gobble_input):
5793 (record_asynch_buffer_change) [USABLE_SIGIO]:
5794 (store_user_signal_events):
5795 No need to mess with signal mask.
5796 (gobble_input): If blocking input and there are terminals, simply
5797 set pending_signals to 1 and return. All hooks changed to not
5798 worry about whether input is blocked.
5799 (process_pending_signals): Clear pending_signals before processing
5800 them, in case a signal comes in while we're processing.
5801 By convention callers now test pending_signals before calling us.
5802 (UNBLOCK_INPUT_TO, unblock_input, totally_unblock_input):
5803 New functions, to support changes to blockinput.h.
5804 (handle_input_available_signal): Now extern.
5805 (reinvoke_input_signal): Remove. All uses replaced by
5807 (quit_count): Now volatile, since a signal handler uses it.
5808 (handle_interrupt): Now takes bool IN_SIGNAL_HANDLER as arg.
5809 All callers changed. Block SIGINT only if not already blocked.
5810 Clear sigmask reliably, even if Fsignal returns, which it can.
5811 Omit unnecessary accesses to volatile var.
5812 (quit_throw_to_read_char): No need to restore sigmask.
5813 * keyboard.c (gobble_input, handle_user_signal):
5814 * process.c (wait_reading_process_output):
5815 Call signal-handling code rather than killing ourselves.
5816 * lisp.h: Include <float.h>, for...
5817 (IEEE_FLOATING_POINT): New macro, moved here to avoid duplication.
5818 (pending_signals): Now volatile.
5819 (syms_of_data): Now const if IEEE floating point.
5820 (handle_input_available_signal) [USABLE_SIGIO]:
5821 (terminate_due_to_signal, record_child_status_change): New decls.
5822 * process.c (create_process): Avoid disaster if memory is exhausted
5823 while we're processing a vfork, by tightening the critical section
5825 (send_process_frame, process_sent_to, handle_pipe_signal)
5826 (deliver_pipe_signal): Remove. No longer needed, as Emacs now
5828 (send_process): No need for setjmp/longjmp any more, since the
5829 SIGPIPE stuff is now gone. Instead, report an error if errno
5831 (record_child_status_change): Now extern. PID and W are now args.
5832 Return void, not bool. All callers changed.
5833 * sysdep.c (wait_debugging) [(BSD_SYSTEM || HPUX) && !defined (__GNU__)]:
5834 Remove. All uses removed. This bug should be fixed now in a
5836 (wait_for_termination_1): Use waitpid rather than sigsuspend,
5837 and record the child status change directly. This avoids the
5838 need to futz with the signal mask.
5839 (process_fatal_action): Move here from emacs.c.
5840 (emacs_sigaction_flags): New function, containing
5841 much of what used to be in emacs_sigaction_init.
5842 (emacs_sigaction_init): Use it. Block nonfatal system signals that are
5843 caught by emacs, to make races less likely.
5844 (deliver_process_signal): Rename from handle_on_main_thread.
5846 (BACKTRACE_LIMIT_MAX): Now at top level.
5847 (thread_backtrace_buffer, threadback_backtrace_pointers):
5849 (deliver_thread_signal, deliver_fatal_thread_signal):
5850 New functions, for more-accurate delivery of thread-specific signals.
5851 (handle_fatal_signal, deliver_fatal_signal): Move here from emacs.c.
5852 (deliver_arith_signal): Handle in this thread, not
5853 in the main thread, since it's triggered by this thread.
5854 (maybe_fatal_sig): New function.
5855 (init_signals): New arg DUMPING so that we can be more accurate
5856 about whether we're dumping. Caller changed.
5857 Treat thread-specific signals differently from process-general signals.
5858 Block all signals while handling fatal error; that's safer.
5859 xsignal from SIGFPE only on non-IEEE hosts, treating it as fatal
5861 When batch, ignore SIGHUP, SIGINT, SIGTERM if they were already ignored.
5862 Ignore SIGPIPE unless batch.
5863 (emacs_backtrace): Output backtrace for the appropriate thread,
5864 which is not necessarily the main thread.
5865 * syssignal.h: Include <stdbool.h>.
5866 (emacs_raise): New macro.
5867 * xterm.c (x_connection_signal): Remove; no longer needed
5868 now that we use sigaction.
5869 (x_connection_closed): No need to mess with sigmask now.
5870 (x_initialize): No need to reset SIGPIPE handler here, since
5871 init_signals does this for us now.
5873 2012-09-23 Jan Djärv <jan.h.d@swipnet.se>
5875 * nsterm.m (ns_dumpglyphs_image): dr is a new rect to draw image into,
5876 background rect may be larger (Bug#12245).
5878 2012-09-23 Chong Yidong <cyd@gnu.org>
5880 * keyboard.c (timer_check): Avoid quitting during Fcopy_sequence.
5882 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
5884 * .gdbinit: Just stop at fatal_error_backtrace.
5885 See Stefan Monnier's request in
5886 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00549.html>.
5887 Remove no-longer-used query of system type.
5889 2012-09-22 Chong Yidong <cyd@gnu.org>
5891 * search.c (Freplace_match): Doc fix (Bug#12325).
5893 * minibuf.c (Finternal_complete_buffer): Doc fix (Bug#12391).
5895 * editfns.c (Fline_beginning_position): Doc fix (Bug#12416).
5896 (Fline_end_position): Doc fix.
5898 * cmds.c (Fforward_char, Fbackward_char): Doc fix (Bug#12414).
5900 2012-09-22 Chong Yidong <cyd@gnu.org>
5902 * dispextern.h (struct image_type): Add new slot, storing a type
5903 initialization function.
5905 * image.c (define_image_type): Call the image initializer function
5906 if it is defined. Arguments and return value changed.
5907 (valid_image_p, make_image): Callers changed.
5908 (xbm_type, xpm_type, pbm_type, png_type, jpeg_type, tiff_type)
5909 (gif_type, imagemagick_type, svg_type, gs_type):
5910 Add initialization functions.
5911 (Finit_image_library): Call lookup_image_type.
5912 (CHECK_LIB_AVAILABLE): Macro deleted.
5913 (lookup_image_type): Call define_image_type here, rather than via
5914 Finit_image_library, and without using CHECK_LIB_AVAILABLE.
5915 (syms_of_image): Move define_image_type calls for xbm_type and
5916 pbm_type to lookup_image_type.
5918 2012-09-22 Eli Zaretskii <eliz@gnu.org>
5920 * keyboard.c (timer_check_2): Move calculation of 'timers' and
5921 'idle_timers' from here ...
5922 (timer_check): ... to here. Use Fcopy_sequence to copy the timer
5923 lists, to avoid infloops when the timer does something stupid,
5924 like reinvoke itself with the same or smaller time-out.
5927 2012-09-22 Martin Rudalics <rudalics@gmx.at>
5929 * window.c (Fsplit_window_internal): Handle only Qt value of
5930 Vwindow_combination_limit separately.
5931 (Qtemp_buffer_resize): New symbol.
5932 (Vwindow_combination_limit): New default value.
5935 2012-09-22 Eli Zaretskii <eliz@gnu.org>
5937 * xdisp.c (next_overlay_string): Initialize it->end_charpos for
5938 the new overlay string. (Bug#10159)
5940 2012-09-22 Paul Eggert <eggert@cs.ucla.edu>
5942 * emacs.c (shut_down_emacs): Don't assume stderr is buffered,
5943 or that fprintf is async-signal-safe. POSIX doesn't require
5946 2012-09-22 Chong Yidong <cyd@gnu.org>
5948 * buffer.c (Fset_buffer_modified_p): Handle indirect buffers
5951 2012-09-22 Kenichi Handa <handa@gnu.org>
5953 * composite.c (composition_reseat_it): Handle the case that a
5954 grapheme cluster is not covered by a single font (Bug#12352).
5956 2012-09-21 Chong Yidong <cyd@gnu.org>
5958 * image.c (define_image_type): Avoid adding duplicate types to
5959 image_types (Bug#12463). Suggested by Jörg Walter.
5961 2012-09-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5963 * unexmacosx.c: Define LC_DATA_IN_CODE if not defined.
5964 (print_load_command_name): Add case LC_DATA_IN_CODE.
5965 (dump_it) [LC_DATA_IN_CODE]: Call copy_linkedit_data.
5967 2012-09-21 Glenn Morris <rgm@gnu.org>
5969 * eval.c (Frun_hook_with_args_until_success)
5970 (Frun_hook_with_args_until_failure): Doc fixes. (Bug#12393)
5972 2012-09-21 Andreas Schwab <schwab@linux-m68k.org>
5974 * fileio.c (Ffile_selinux_context): Only call freecon when
5975 lgetfilecon succeeded.
5976 (Fset_file_selinux_context): Likewise. (Bug#12444)
5978 2012-09-21 Eli Zaretskii <eliz@gnu.org>
5980 * xdisp.c (try_window_reusing_current_matrix): Under bidi
5981 reordering, locate the cursor by calling set_cursor_from_row; if
5982 that fails, clear the desired glyph matrix before returning a
5983 failure indication to the caller. Fixes leaving garbled display
5984 when fast scrolling with a down-key. (Bug#12403)
5985 (compute_stop_pos_backwards): Fix a typo that caused crashes while
5986 scrolling through multibyte text.
5988 2012-09-20 Stefan Monnier <monnier@iro.umontreal.ca>
5990 * alloc.c (mark_object) <PVEC_WINDOW>: Mark prev/next_buffers *after*
5991 calling mark_vectorlike since that's the one that marks the window.
5992 (mark_discard_killed_buffers): Mark the final cdr.
5993 * window.h (struct window): Move prev/next_buffers to the
5994 non-standard fields.
5995 * window.c (make_window): Initialize prev/next_buffers manually.
5997 2012-09-20 Paul Eggert <eggert@cs.ucla.edu>
5999 Omit unused arg EXPECTED from socket hooks.
6000 * keyboard.c (gobble_input, read_avail_input, tty_read_avail_input):
6001 * nsterm.m (ns_term_init):
6002 * termhooks.h (struct terminal.read_socket_hook):
6003 * w32inevt.c (w32_console_read_socket):
6004 * w32term.c (w32_read_socket):
6005 * xterm.c (XTread_socket):
6006 Omit unused arg EXPECTED. All callers changed.
6007 (store_user_signal_events): Return void, not int, since callers no
6008 longer care about the return value. All uses changed.
6010 2012-09-20 Juanma Barranquero <lekktu@gmail.com>
6012 * w32gui.h (XParseGeometry): Do not declare.
6014 2012-09-19 Paul Eggert <eggert@cs.ucla.edu>
6016 * w32inevt.c (w32_console_read_socket): Return -1 on failure, not 0.
6017 Ignore 'expected'. See Eli Zaretskii in
6018 <http://bugs.gnu.org/12471#8> (last line).
6020 * frame.c (read_integer): Remove. All uses replaced by strtol/strtoul.
6021 (XParseGeometry): Now static. Substitute extremal values for
6022 values that are out of range.
6024 2012-09-19 Jan Djärv <jan.h.d@swipnet.se>
6026 * w32xfns.c (read_integer, XParseGeometry): Move to frame.c.
6028 * nsfns.m (XParseGeometry): Remove.
6029 (Fx_create_frame): Call x_set_offset to correctly interpret
6030 top_pos in geometry.
6032 * frame.c (read_integer, XParseGeometry): Move from w32xfns.c.
6033 (Fx_parse_geometry): If there is a space in string, call
6034 Qns_parse_geometry, otherwise do as on other terms (Bug#12368).
6036 2012-09-17 Eli Zaretskii <eliz@gnu.org>
6038 * search.c (scan_buffer): Use character positions in calls to
6039 region_cache_forward and region_cache_backward, not byte
6040 positions. (Bug#12196)
6042 * w32term.c (w32_read_socket): Set pending_signals to 1, like
6043 xterm.c does. Reported by Daniel Colascione <dancol@dancol.org>.
6045 * ralloc.c (r_alloc_init) [!SYSTEM_MALLOC]: Initialize
6046 __malloc_extra_blocks to 32 instead of 64, like alloc.c did in
6047 emacs_blocked_malloc, now deleted.
6049 2012-09-17 Paul Eggert <eggert@cs.ucla.edu>
6051 Remove no-longer-needed Solaris 2.4 vfork bug workaround.
6052 The workaround was for improving performance on Solaris 2.4, but
6053 is getting in the way now. Emacs will still work if someone is
6054 still running Solaris 2.4 in a museum somewhere; Sun dropped
6055 support for Solaris 2.4 in 2003.
6056 * callproc.c (Fcall_process) [HAVE_WORKING_VFORK]:
6057 * process.c (create_process) [HAVE_WORKING_VFORK]:
6058 Omit now-unnecessary workaround for the Solaris 2.4 vfork bug,
6059 since Emacs no longer uses vfork on that platform.
6061 2012-09-17 Glenn Morris <rgm@gnu.org>
6063 * emacs.c: Use COPYRIGHT.
6065 2012-09-16 Paul Eggert <eggert@cs.ucla.edu>
6067 Remove configure's --without-sync-input option (Bug#12450).
6068 When auditing signal-handling in preparation for cleaning it up,
6069 I found that SYNC_INPUT has race conditions and would be a real
6070 pain to fix. Since it's an undocumented and deprecated
6071 configure-time option, now seems like a good time to remove it.
6072 Also see <http://bugs.gnu.org/11080#16>.
6073 * alloc.c (_bytes_used, __malloc_extra_blocks, _malloc_internal)
6074 (_free_internal) [!DOUG_LEA_MALLOC]: Remove decls.
6075 (alloc_mutex) [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
6076 (malloc_hysteresis):
6077 (check_depth) [XMALLOC_OVERRUN_CHECK]:
6078 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT):
6079 (__malloc_hook, __realloc_hook, __free_hook, BYTES_USED)
6080 (dont_register_blocks, bytes_used_when_reconsidered)
6081 (bytes_used_when_full, emacs_blocked_free, emacs_blocked_malloc)
6082 (emacs_blocked_realloc, reset_malloc_hooks, uninterrupt_malloc):
6083 [!SYSTEM_MALLOC && !SYNC_INPUT]:
6084 Remove. All uses removed.
6085 (MALLOC_BLOCK_INPUT, MALLOC_UNBLOCK_INPUT): Use a different
6086 implementation, one that depends on whether the new macro
6087 XMALLOC_BLOCK_INPUT_CHECK is defined, not on whether SYNC_INPUT
6089 * atimer.c (run_timers, handle_alarm_signal):
6090 * keyboard.c (pending_signal, poll_for_input_1, poll_for_input)
6091 (handle_async_input, process_pending_signals)
6092 (handle_input_available_signal, init_keyboard):
6093 * nsterm.m (ns_read_socket):
6094 * process.c (wait_reading_process_output):
6095 * regex.c (immediate_quit, IMMEDIATE_QUIT_CHECK):
6096 * sysdep.c (emacs_sigaction_init) [SA_RESTART]:
6098 * xterm.c (XTread_socket):
6100 * conf_post.h (SA_RESTART) [IRIX6_5]: Do not #undef.
6101 * eval.c (handling_signal): Remove. All uses removed.
6102 * lisp.h (ELSE_PENDING_SIGNALS): Remove.
6103 All uses replaced with the SYNC_INPUT version.
6104 (reset_malloc_hooks, uninterrupt_malloc, handling_signal):
6106 * sysdep.c, syssignal.h (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6109 * font.c (Ffont_shape_gstring): Remove unused local.
6111 2012-09-16 Glenn Morris <rgm@gnu.org>
6113 * Makefile.in (clean): No longer run nextstep's clean.
6115 * Makefile.in (ns_appdir, ns_appbindir, ns_appsrc): Remove variables.
6117 (ns-app): Move here from ns.mk, and simplify.
6118 (clean): Simplify nextstep entry.
6119 * ns.mk: Remove file.
6121 2012-09-17 Kenichi Handa <handa@gnu.org>
6123 * font.c (Ffont_shape_gstring): Fix previous change; GLYPHs may
6124 not covert the last few charactes.
6126 2012-09-16 Kenichi Handa <handa@gnu.org>
6128 * font.c (Ffont_shape_gstring): Don't adjust grapheme cluster
6129 here, but just check the validity of glyphs in the glyph-string.
6131 2012-09-16 Martin Rudalics <rudalics@gmx.at>
6133 * window.c (Fwindow_parameter, Fset_window_parameter):
6134 Accept any window as argument (Bug#12452).
6136 2012-09-16 Jan Djärv <jan.h.d@swipnet.se>
6138 * nsfns.m (Fx_open_connection): Move initialization of ns_*_types
6139 to ns_term_init to avoid memory leak.
6141 * nsterm.m (ns_update_begin): Initialize bp after lcokFocus, use
6142 explicit retain/release.
6143 (ns_term_init): Only allow one display. Initialize outerpool and
6146 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
6148 Port _setjmp fix to POSIXish hosts as well as Microsoft.
6149 * image.c (_setjmp) [!HAVE__SETJMP]: Restore definition, as
6150 it's needed on POSIXish hosts that lack _setjmp. Attempt to solve
6151 the Microsoft problem in a different way, by altering ../nt/config.nt.
6153 2012-09-15 Eli Zaretskii <eliz@gnu.org>
6168 * w16select.c: Remove inclusion of setjmp.h, as it is now included
6169 by lisp.h. This completes removal of setjmp.h inclusion
6170 erroneously announced in the previous commit. (Bug#12446)
6172 * lisp.h [!HAVE__SETJMP, !HAVE_SIGSETJMP]: Make the commentary
6175 * image.c (_setjmp) [!HAVE__SETJMP]: Define only if 'setjmp' is
6176 not defined as a macro. The latter happens on MS-Windows.
6179 2012-09-15 Paul Eggert <eggert@cs.ucla.edu>
6181 Port better to POSIX hosts lacking _setjmp (Bug#12446).
6182 * lisp.h: Include <setjmp.h> here, since we use its symbols here.
6183 Some instances of '#include <setjmp.h>' removed, if the
6184 only reason for the instance was because "lisp.h" was included.
6185 (sys_jmp_buf, sys_setjmp, sys_longjmp): New symbols.
6186 Unless otherwise specified, replace all uses of jmp_buf, _setjmp,
6187 and _longjmp with the new symbols. Emacs already uses _setjmp if
6188 available, so this change affects only POSIXish hosts that have
6189 sigsetjmp but not _setjmp, such as some versions of Solaris and
6190 Unixware. (Also, POSIX-2008 marks _setjmp as obsolescent.)
6191 * image.c (_setjmp, _longjmp) [HAVE_PNG && !HAVE__SETJMP]: New macros.
6192 (png_load_body) [HAVE_PNG]:
6193 (PNG_LONGJMP) [HAVE_PNG && PNG_LIBPNG_VER < 10500]:
6194 (PNG_JMPBUF) [HAVE_PNG && PNG_LIBPNG_VER >= 10500]:
6195 Use _setjmp and _longjmp rather than sys_setjmp and sys_longjmp,
6196 since PNG requires jmp_buf. This is the only exception to the
6197 general rule that we now use sys_setjmp and sys_longjmp.
6198 This exception is OK since this code does not change the signal
6199 mask or longjmp out of a signal handler.
6201 2012-09-14 Paul Eggert <eggert@cs.ucla.edu>
6203 * alloc.c [!SYSTEM_MALLOC && !SYNC_INPUT && HAVE_PTHREAD]:
6204 Include "syssignal.h", for 'main_thread'.
6206 2012-09-14 Dmitry Antipov <dmantipov@yandex.ru>
6208 Avoid out-of-range marker position (Bug#12426).
6209 * insdel.c (replace_range, replace_range_2):
6210 Adjust markers before overlays, as suggested by comments.
6211 (insert_1_both, insert_from_buffer_1, adjust_after_replace):
6212 Remove redundant check before calling offset_intervals.
6214 2012-09-14 Martin Rudalics <rudalics@gmx.at>
6216 * xdisp.c (Fformat_mode_line): Unconditionally save/restore
6217 current buffer (Bug#12387).
6219 2012-09-14 Juanma Barranquero <lekktu@gmail.com>
6221 * makefile.w32-in ($(BLD)/alloc.$(O)): Update dependencies.
6223 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
6225 Use a more backwards-compatible timer format (Bug#12430).
6226 * keyboard.c (decode_timer): Get PSECS from the 8th (origin-0)
6227 vector element, not from the 4th, since PSECS is now at the end.
6228 (Fcurrent_idle_time): Doc fix.
6230 2012-09-13 Dmitry Antipov <dmantipov@yandex.ru>
6232 Function to mark objects and remove killed buffers at once.
6233 * alloc.c (discard_killed_buffers): Rename to ...
6234 (mark_discard_killed buffers) ... new name. Add marking
6235 of remaining objects. Fix comment. Adjust users.
6236 (mark_object): Do not touch frame buffer lists here.
6237 * frame.c (delete_frame): Reset frame buffer lists here.
6239 2012-09-13 Paul Eggert <eggert@cs.ucla.edu>
6241 Better workaround for GNOME bug when --enable-gcc-warnings.
6242 * emacsgtkfixed.c (G_STATIC_ASSERT): Remove, undoing last change.
6243 Instead, disable -Wunused-local-typedefs. See Dmitry Antipov in
6244 <http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00335.html>.
6246 Simplify SIGIO usage (Bug#12408).
6247 The code that dealt with SIGIO was crufty and confusing, e.g., it
6248 played tricks like "#undef SIGIO" but these tricks were not used
6249 consistently. Simplify mostly by not #undeffing standard symbols,
6250 e.g., use "defined USABLE_SIGIO" (our symbol, which we can define
6251 or not as we please) rather than "defined SIGIO" (standard symbol
6252 that we probably shouldn't #undef).
6253 * conf_post.h [USG5_4]: Do not include <sys/wait.h> here.
6254 Modules that need it can include it.
6255 [USG5_4 && emacs]: Likewise, do not include the streams stuff here.
6256 * dispextern.h (ignore_sigio): New decl.
6257 * emacs.c (shut_down_emacs): Invoke unrequest_sigio
6258 unconditionally, since it's now a no-op if !USABLE_SIGIO.
6259 * emacs.c (shut_down_emacs):
6260 * keyboard.c (kbd_buffer_store_event_hold):
6261 Use ignore_sigio rather than invoking 'signal' directly.
6262 * keyboard.c (USABLE_FIONREAD && USG5_4): Include <sys/filio.h>,
6264 (FIONREAD, SIGIO): Do not #undef.
6265 (tty_read_avail_input): Use #error rather than a syntax error.
6266 * process.c [USG5_4]: Include <sys/stream.h> and <sys/stropts.h>,
6267 for I_PIPE, used by SETUP_SLAVE_PTY.
6268 (DATAGRAM_SOCKETS): Simplify defn, based on USABLE_FIONREAD.
6269 * sysdep.c (croak): Remove; no longer needed. This bit of
6270 temporary code, with Fred N. Fish's comment that it's temporary,
6271 has been in Emacs since at least 1992!
6272 (init_sigio, reset_sigio, request_sigio, unrequest_sigio):
6273 Arrange for them to be no-ops in all cases when ! USABLE_SIGIO.
6274 * syssignal.h (croak): Remove decl.
6275 (SIGIO, SIGPOO, SIGAIO, SIGPTY): Do not #undef; that's too fragile.
6276 * systty.h [!NO_TERMIO]: Do not include <termio.h>; no longer needed
6277 now that we're termios-only.
6278 (FIONREAD, ASYNC) [BROKEN_FIONREAD]: Do not #undef.
6279 * term.c (dissociate_if_controlling_tty): Use #error rather than
6282 Work around GCC and GNOME bugs when --enable-gcc-warnings.
6283 * emacsgtkfixed.c (G_STATIC_ASSERT): Redefine to use 'verify',
6284 to work around GNOME bug 683906.
6285 * image.c (jpeg_load_body) [HAVE_JPEG && lint]: Pacify gcc -Wclobber.
6286 (struct my_jpeg_error_mgr) [HAVE_JPEG && lint]: New member fp.
6287 This works around GCC bug 54561.
6289 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
6291 More fixes for 'volatile' and setjmp/longjmp.
6292 * eval.c (Fdefvar, Fcondition_case): Remove unnecessary 'volatile's.
6293 * image.c (struct png_load_context) [HAVE_PNG]: New type.
6294 (png_load_body) [HAVE_PNG]:
6295 (jpeg_load_body) [HAVE_JPEG]:
6296 New function, with most of the old parent function's body.
6297 (png_load) [HAVE_PNG]:
6298 (jpeg_load) [HAVE_JPEG]:
6299 Invoke the new function, to avoid longjmp munging our locals.
6300 (struct my_jpeg_error_mgr) [HAVE_JPEG]: New members cinfo, failure_code.
6301 (my_error_exit) [HAVE_JPEG]: Don't trust 'setjmp' to return 2 when
6302 longjmp is passed 2, as the C standard doesn't guarantee this.
6303 Instead, store the failure code into mgr->failure_code.
6305 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
6307 * keyboard.c (read_char, requeued_events_pending_p, Finput_pending_p)
6308 (Fdiscard_input, quit_throw_to_read_char, init_keyboard)
6309 (syms_of_keyboard): Remove support for unread-command-char.
6311 2012-09-12 Eli Zaretskii <eliz@gnu.org>
6313 * w32proc.c (sys_kill): If PID is our process ID and the signal is
6314 SIGABRT, call emacs_abort. Avoids silently exiting upon assertion
6315 violation. (Bug#12426)
6317 2012-09-12 Paul Eggert <eggert@cs.ucla.edu>
6319 * image.c (jpeg_memory_src): Don't assume string len fits in unsigned.
6321 2012-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
6323 * eval.c: Add `inhibit-debugger'.
6324 (Qinhibit_debugger): New symbol.
6325 (call_debugger): Bind it instead of Qdebug_on_error.
6326 (maybe_call_debugger): Test Vinhibit_debugger.
6327 (syms_of_eval): Define inhibit-debugger.
6328 * xdisp.c (set_message): Don't bind Qinhibit_debug_on_message.
6329 (syms_of_xdisp): Remove inhibit-debug-on-message.
6331 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
6333 Avoid _setjmp/_longjmp problems with local nonvolatile variables.
6334 If a nonvolatile local variable is written before a _longjmp to
6335 the frame containing the variable, and is read after the _longjmp,
6336 the value read is indeterminate. Some local variables of type
6337 'struct handler' and 'struct catchtag' are used in this way, so
6338 mark each of their slots as volatile if the slot can be set before
6339 _longjmp and read afterwards.
6340 * lisp.h (struct handler): var and chosen_clause are now volatile.
6341 (struct catchtag): val, next, and pdlcount are now volatile.
6343 * bidi.c (bidi_push_it, bidi_pop_it):
6344 * fns.c (copy_hash_table):
6345 * image.c (define_image_type):
6346 * keyboard.c (kbd_buffer_store_event_hold):
6347 * process.c (Fprocess_send_eof):
6348 * xfaces.c (x_create_gc) [HAVE_NS]:
6349 * xgselect.c (xg_select):
6350 Prefer assignment to memcpy when either will do.
6352 * alloc.c (discard_killed_buffers): Tune and simplify a bit.
6353 Use pointer-to-a-pointer to simplify and avoid a NILP check each
6354 time an item is removed. No need to mark this function 'inline';
6355 the compiler knows better than we do.
6357 2012-09-11 Jan Djärv <jan.h.d@swipnet.se>
6359 * nsterm.m (ns_judge_scroll_bars): Pass NO to updateFrameSize.
6360 (updateFrameSize:): Add delay parameter to updateFrameSize, send it
6361 to change_frame_size (Bug#12388).
6362 (windowDidResize:): Pass YES to updateFrameSize.
6364 * nsterm.h: Add delay parameter to updateFrameSize.
6366 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
6368 Discard killed buffers from deleted window and frame objects.
6369 This reduces an amount of references to killed buffers and
6370 helps GC to reclaim them faster.
6371 * alloc.c (discard_killed_buffers): New function.
6372 (mark_object): Use it for deleted windows and frames.
6373 (mark_object): If symbol's value is set up for a killed buffer
6374 or deleted frame, restore its global binding.
6375 * data.c (swap_in_global_binding): Add GC notice.
6376 (swap_in_symval_forwarding): Use convenient set_blv_where.
6377 * window.c (wset_next_buffers, wset_prev_buffers): Move ...
6378 * window.h: ... to here.
6380 2012-09-11 Dmitry Antipov <dmantipov@yandex.ru>
6382 Convenient macro to check whether the buffer is live.
6383 * buffer.h (BUFFER_LIVE_P): New macro.
6384 * alloc.c, buffer.c, editfns.c, insdel.c, lread.c, marker.c:
6385 * minibuf.c, print.c, process.c, window.c, xdisp.c: Use it.
6387 2012-09-11 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6389 * xdisp.c (right_overwritten, right_overwriting): Also handle gstring
6390 composition cases (Bug#12364).
6392 * xterm.c (x_draw_glyph_string): Avoid overwriting inverted left
6393 overhang of succeeding glyphs overlapping box cursor.
6395 * w32term.c (x_draw_glyph_string): Likewise.
6397 2012-09-11 Paul Eggert <eggert@cs.ucla.edu>
6399 Simplify, document, and port floating-point (Bug#12381).
6400 The porting part of this patch fixes bugs on non-IEEE platforms
6401 with frexp, ldexp, logb.
6402 * data.c, lisp.h (Qdomain_error, Qsingularity_error, Qunderflow_error):
6404 * floatfns.c: Simplify discussion of functions that Emacs doesn't
6405 support, by removing commented-out code and briefly listing the
6406 C89 functions excluded. The commented-out stuff was confusing
6407 maintenance, e.g., we thought we needed cbrt but it was commented out.
6408 (logb): Remove decl; no longer needed.
6409 (isfinite): New macro, if not already supplied.
6410 (isnan): Don't replace any existing macro.
6411 (Ffrexp, Fldexp): Define even if !HAVE_COPYSIGN, as frexp and ldexp
6412 are present on all C89 platforms.
6413 (Ffrexp): Do not special-case zero, as frexp does the right thing
6415 (Flogb): Do not use logb, as it doesn't have the desired meaning
6416 on hosts that use non-base-2 floating point. Instead, stick with
6417 frexp, which is C89 anyway. Do not pass an infinity or a NaN to
6418 frexp, to avoid getting an unspecified result.
6420 * xdisp.c (Qinhibit_debug_on_message): Now static.
6422 2012-09-10 Jan Djärv <jan.h.d@swipnet.se>
6424 * nsterm.m (ns_update_begin): Set clip path to whole view by using
6425 NSBezierPath (Bug#12131).
6427 2012-09-10 Chong Yidong <cyd@gnu.org>
6429 * fns.c (Fdelq, Fdelete): Doc fix.
6431 2012-09-10 Paul Eggert <eggert@cs.ucla.edu>
6433 * lisp.h (XSETINT, XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL)
6434 (XSETFLOAT, XSETMISC): Parenthesize macro bodies.
6436 2012-09-09 Stefan Monnier <monnier@iro.umontreal.ca>
6438 * lisp.h (make_lisp_ptr): New macro to replace XSET.
6439 (XSETCONS, XSETVECTOR, XSETSTRING, XSETSYMBOL, XSETFLOAT, XSETMISC):
6442 2012-09-09 Eli Zaretskii <eliz@gnu.org>
6444 * fringe.c (draw_fringe_bitmap_1): Don't reduce the width of the
6445 left fringe if the window has a left margin. This avoids leaving
6446 traces of the cursor because its leftmost pixel is not drawn over.
6448 * dispnew.c (update_window_line): When the left margin area of a
6449 screen line is updated, set the redraw_fringe_bitmaps_p flag of
6450 that screen line. (Bug#12277)
6452 2012-09-09 Paul Eggert <eggert@cs.ucla.edu>
6454 Assume C89 or later for math functions (Bug#12381).
6455 This simplifies the code, and makes it a bit smaller and faster,
6456 and (most important) makes it easier to clean up signal handling
6457 since we can stop worring about floating-point exceptions in
6458 library code. That was a problem before C89, but the problem
6459 went away many years ago on all practical Emacs targets.
6460 * data.c, image.c, lread.c, print.c:
6461 Don't include <math.h>; no longer needed.
6462 * data.c, floatfns.c (IEEE_FLOATING_POINT): Don't worry that it
6463 might be autoconfigured, as that never happens.
6465 * doprnt.c (DBL_MAX_10_EXP):
6466 * print.c (DBL_DIG):
6467 Remove. C89 or later always defines these.
6468 * floatfns.c (HAVE_MATHERR, FLOAT_CHECK_ERRNO, FLOAT_CHECK_DOMAIN)
6469 (in_float, float_error_arg, float_error_arg2, float_error_fn_name)
6470 (arith_error, domain_error, domain_error2):
6471 Remove all this pre-C89 cruft. Do not include <errno.h> as that's
6472 no longer needed -- we simply return what C returns. All uses removed.
6473 (IN_FLOAT, IN_FLOAT2): Remove. All uses replaced with
6475 (FLOAT_TO_INT, FLOAT_TO_INT2, range_error, range_error2):
6476 Remove. All uses expanded, as these macros are no longer used
6477 more than once and are now more trouble than they're worth.
6478 (Ftan): Use tan, not sin / cos.
6479 (Flogb): Assume C89 frexp.
6480 (fmod_float): Assume C89 fmod.
6481 (matherr) [HAVE_MATHERR]: Remove; no longer needed.
6482 (init_floatfns): Remove. All uses removed.
6484 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6486 * nsterm.m (ns_draw_fringe_bitmap, ns_dumpglyphs_image): Take back
6487 compositeToPoint for OSX < 10.6 (Bug#12390).
6489 2012-09-08 Paul Eggert <eggert@cs.ucla.edu>
6491 * floatfns.c (Ftan): Use tan (x), not (sin (x) / cos (x)).
6492 This produces more-accurate results.
6494 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6496 * nsterm.m (updateFrameSize): Call setFrame: on the view when size
6497 changes (Bug#12088).
6499 2012-09-08 Chong Yidong <cyd@gnu.org>
6501 * syntax.c (Fstring_to_syntax): Doc fix.
6503 2012-09-08 Jan Djärv <jan.h.d@swipnet.se>
6505 * nsterm.m (ns_clip_to_row): Remove code that deals with drawing fringe
6506 in the internal border.
6507 (x_set_window_size): Remove static variables and their usage.
6508 (ns_redraw_scroll_bars): Fix NSTRACE arg.
6509 (ns_after_update_window_line, ns_draw_fringe_bitmap):
6510 Remove fringe/internal border adjustment (Bug#11052).
6511 (ns_draw_fringe_bitmap): Make code more like other terms (xterm.c).
6512 (ns_draw_window_cursor): Remove fringe/internal border adjustment.
6513 (ns_fix_rect_ibw): Remove.
6514 (ns_get_glyph_string_clip_rect): Remove call to ns_fix_rect_ibw.
6515 (ns_dumpglyphs_box_or_relief): Ditto.
6516 (ns_maybe_dumpglyphs_background): Remove fringe/internal border
6518 (ns_dumpglyphs_image): Ditto.
6519 (ns_dumpglyphs_stretch): Fix coding style. Remove fringe/internal
6521 (ns_set_vertical_scroll_bar): Remove variables barOnVeryLeft/Right and
6522 their usage. Add fringe_extended_p and its use as in other terms.
6523 (ns_judge_scroll_bars): Code style fix. Call updateFrameSize if
6524 scroll bar was removed.
6525 (updateFrameSize): New function.
6526 (windowDidResize): Move code to updateFrameSize and call it.
6528 * nsterm.h (EmacsView): Add updateFrameSize.
6530 2012-09-07 Chong Yidong <cyd@gnu.org>
6532 * textprop.c (Fget_text_property): Minor doc fix (Bug#12323).
6534 * data.c (Flocal_variable_if_set_p): Doc fix (Bug#10713).
6536 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
6538 More signal-handler cleanup (Bug#12327).
6539 * emacs.c (main): Convert three 'signal' calls to 'sigaction' calls.
6540 Problem introduced when merging patches. Noted by Eli Zaretskii in
6541 <http://bugs.gnu.org/12327#67>.
6542 * floatfns.c: Comment fix.
6543 * lisp.h (force_auto_save_soon): Declare regardless of SIGDANGER.
6544 SIGDANGER might not be in scope so "#ifdef SIGDANGER" is not right,
6545 and anyway the declaration is harmless even if SIGDANGER is not defined.
6546 * syssignal.h (SIGIO): Also #undef if (! defined FIONREAD ||
6547 defined BROKEN_FIONREAD). systty.h formerly did this, but other
6548 source files not surprisingly expected syssignal.h to define, or
6549 not define, SIGIO, and it's cleaner to do it that way, for consistency.
6550 Include <sys/ioctl.h>, for FIONREAD.
6551 * systty.h (SIGIO): Do not #undef here; it's now syssignal.h's job.
6552 This eliminates a problem whereby other files mysteriously had
6553 to include "syssignal.h" before including "systty.h" if they
6554 wanted to use "#ifdef SIGIO".
6556 2012-09-07 Eli Zaretskii <eliz@gnu.org>
6558 * w32proc.c (sigaction): New function, emulates Posix 'sigaction'.
6560 * w32.c (sigemptyset): Empty the set.
6561 (sigsetmask, sigmask, sigblock, sigunblock): Remove unused functions.
6563 * alloc.c [ENABLE_CHECKING]: Include signal.h, since we need SIGABRT.
6565 2012-09-07 Dmitry Antipov <dmantipov@yandex.ru>
6567 * alloc.c (mark_buffer): Revert unsafe marking optimization.
6568 (mark_object): Likewise for frame objects.
6570 2012-09-07 Paul Eggert <eggert@cs.ucla.edu>
6572 * syssignal.h (handle_on_main_thread): Always declare,
6573 even if FORWARD_SIGNAL_TO_MAIN_THREAD is not defined.
6574 This ports to platforms without HAVE_PTHREAD.
6576 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
6578 Signal-handler cleanup (Bug#12327).
6579 Emacs's signal handlers were written in the old 4.2BSD style with
6580 sigblock and sigmask and so forth, and this led to some
6581 inefficiencies and confusion. Rewrite these to use
6582 pthread_sigmask etc. without copying signal sets around. Also,
6583 get rid of the confusing macros 'SIGNAL_THREAD_CHECK' and
6584 'signal', and instead use functions that do not attempt to take
6585 over the system name space. This patch causes Emacs's text
6586 segment to shrink by 0.7% on my platform, Fedora 17 x86-64.
6587 * alloc.c, emacsgtkfixed.c, nsfns.m, widget.c, xmenu.c:
6588 Do not include <signal.h> or "syssignal.h", as these
6589 modules do not use signals.
6590 * atimer.c, callproc.c, data.c, dispnew.c, emacs.c, floatfns.c:
6591 * gtkutil.c, keyboard.c, process.c, sound.c, sysdep.c, term.c, xterm.c:
6592 Do not include <signal.h>, as "syssignal.h" does that for us now.
6593 * atimer.c (sigmask_atimers): New function.
6594 (block_atimers, unblock_atimers): New functions,
6595 replacing the old macros BLOCK_ATIMERS and UNBLOCK_ATIMERS.
6597 * conf_post.h [SIGNAL_H_AHB]: Do not include <signal.h>;
6598 no longer needed here.
6599 * emacs.c (main): Inspect existing signal handler with sigaction,
6600 so that there's no need to block and unblock SIGHUP.
6601 * sysdep.c (struct save_signal): New member 'action', replacing
6602 old member 'handler'.
6603 (save_signal_handlers, restore_signal_handlers):
6604 Use sigaction instead of 'signal' to save and restore.
6605 (get_set_sighandler, set_sighandler) [!WINDOWSNT]:
6606 New function. All users of 'signal' modified to use set_sighandler
6607 if they're writeonly, and to use sys_signal if they're read+write.
6608 (emacs_sigaction_init, forwarded_signal): New functions.
6609 (sys_signal): Remove. All uses replaced by calls to sigaction
6610 and emacs_sigaction_init, or by direct calls to 'signal'.
6611 (sys_sigmask) [!__GNUC__]: Remove; no longer needed.
6612 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove;
6613 all uses replaced by pthread_sigmask etc. calls.
6614 * syssignal.h: Include <signal.h>.
6615 (emacs_sigaction_init, forwarded_signal): New decls.
6616 (SIGMASKTYPE): Remove. All uses replaced by its definiens, sigset_t.
6617 (SIGEMPTYMASK): Remove; all uses replaced by its definiens, empty_mask.
6618 (sigmask, sys_sigmask): Remove; no longer needed.
6619 (sigpause): Remove. All uses replaced by its definiens, sigsuspend.
6620 (sigblock, sigunblock, sigfree):
6621 (sigsetmask) [!defined sigsetmask]:
6622 Remove. All uses replaced by pthread_sigmask.
6623 (signal): Remove. Its remaining uses (with SIG_DFL and SIG_IGN)
6624 no longer need to be replaced, and its typical old uses
6625 are now done via emacs_sigaction_init and sigaction.
6626 (sys_sigblock, sys_sigunblock, sys_sigsetmask): Remove decls.
6627 (sys_sigdel): Remove; unused.
6628 (NSIG): Remove a FIXME; the code's fine. Remove an unnecessary ifdef.
6630 2012-09-06 Eli Zaretskii <eliz@gnu.org>
6632 * process.c (CAN_HANDLE_MULTIPLE_CHILDREN): Fix a typo that broke
6633 SIGCHLD handling on systems that don't have WNOHANG. (Bug#12327)
6635 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
6637 Explicitly mark buffer_defaults and buffer_local_symbols.
6638 * alloc.c (Fgarbage_collect): Mark buffer_defaults and
6639 mark_local_symbols here.
6640 (mark_object): If GC_CHECK_MARKED_OBJECTS, simplify checking
6641 since special buffers aren't marked here any more.
6642 (allocate_buffer): Chain new buffer with all_buffers here...
6643 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer): ...and
6645 (Vbuffer_defaults, Vbuffer_local_symbols): Remove.
6646 (syms_of_buffer): Remove staticpro of the above.
6647 (init_buffer_once): Set names for buffer_defaults and
6648 buffer_local_symbols.
6650 2012-09-06 Paul Eggert <eggert@cs.ucla.edu>
6652 Use bool for booleans in font-related modules.
6653 * font.c (font_intern_prop, font_style_to_value)
6654 (font_style_symbolic, font_parse_xlfd, font_parse_fcname)
6655 (generate_otf_features, font_check_otf_features, font_check_otf)
6656 (font_match_p, font_list_entities, font_at):
6657 * fontset.c (fontset_id_valid_p, reorder_font_vector
6658 (fontset_find_font, Fset_fontset_font)
6659 (face_suitable_for_char_p) [0]:
6660 * ftfont.c (fc_initialized, ftfont_get_open_type_spec)
6661 (ftfont_open, ftfont_text_extents, ftfont_check_otf):
6662 (m17n_flt_initialized, ftfont_shape_by_flt):
6663 * ftxfont.c (ftxfont_draw_bitmap, ftxfont_draw):
6664 * nsfont.m (nsfont_draw):
6665 * w32font.c (w32font_draw):
6666 * w32term.c (x_draw_glyphless_glyph_string_foreground):
6667 Use bool for booleans.
6668 * font.h: Adjust to above API changes.
6669 (struct font, struct font_driver, struct font_driver_list):
6670 Use bool for booleans.
6671 (struct font): Remove useless member encoding_type.
6673 * fontset.c, xftfont.c: Omit unnecessary static decls.
6675 2012-09-06 Dmitry Antipov <dmantipov@yandex.ru>
6677 * alloc.c (mark_object): Revert window marking code
6678 since it's unsafe for the Fset_window_configuration.
6680 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
6682 Fix race conditions with signal handlers and errno (Bug#12327).
6683 Be more systematic about preserving errno whenever a signal
6684 handler returns, even if it's not in the main thread. Do this by
6685 renaming signal handlers to distinguish between signal delivery
6686 and signal handling. All uses changed.
6687 * atimer.c (deliver_alarm_signal): Rename from alarm_signal_handler.
6688 * data.c (deliver_arith_signal): Rename from arith_error.
6689 * dispnew.c (deliver_window_change_signal): Rename from
6690 window_change_signal.
6691 * emacs.c (deliver_error_signal): Rename from fatal_error_signal.
6692 (deliver_danger_signal) [SIGDANGER]: Rename from memory_warning_signal.
6693 * keyboard.c (deliver_input_available_signal): Rename from
6694 input_available_signal.
6695 (deliver_user_signal): Rename from handle_user_signal.
6696 (deliver_interrupt_signal): Rename from interrupt_signal.
6697 * process.c (deliver_pipe_signal): Rename from send_process_trap.
6698 (deliver_child_signal): Rename from sigchld_handler.
6699 * atimer.c (handle_alarm_signal):
6700 * data.c (handle_arith_signal):
6701 * dispnew.c (handle_window_change_signal):
6702 * emacs.c (handle_fatal_signal, handle_danger_signal):
6703 * keyboard.c (handle_input_available_signal):
6704 * keyboard.c (handle_user_signal, handle_interrupt_signal):
6705 * process.c (handle_pipe_signal, handle_child_signal):
6706 New functions, with the actual signal-handling code taken from the
6707 original respective signal handlers, sans the sporadic attempts to
6708 preserve errno, since that's now done by handle_on_main_thread.
6709 * atimer.c (alarm_signal_handler): Remove unnecessary decl.
6710 * emacs.c, floatfns.c, lisp.h: Remove unused FLOAT_CATCH_SIGKILL cruft.
6711 * emacs.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6713 (main) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6714 Move initialization of main_thread to sysdep.c's init_signals.
6715 * process.c (waitpid) [!WNOHANG]: #define to wait; that's good enough for
6716 our usage, and simplifies the mainline code.
6717 (record_child_status_change): New static function, as a helper
6718 for handle_child_signal, and with most of the old child handler's
6720 (CAN_HANDLE_MULTIPLE_CHILDREN): New constant.
6721 (handle_child_signal): Use the above.
6722 * sysdep.c (main_thread) [FORWARD_SIGNAL_TO_MAIN_THREAD]:
6723 Moved here from emacs.c.
6724 (init_signals) [FORWARD_SIGNAL_TO_MAIN_THREAD]: Initialize it;
6725 code moved here from emacs.c's main function.
6726 * sysdep.c, syssignal.h (handle_on_main_thread): New function,
6727 replacing the old SIGNAL_THREAD_CHECK. All uses changed.
6728 This lets callers save and restore errno properly.
6730 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6732 Remove redundant or unused things here and there.
6733 * lisp.h (CYCLE_CHECK, CHAR_TABLE_TRANSLATE): Remove.
6734 * conf_post.h (RE_TRANSLATE): Use char_table_translate.
6735 * editfns.c (Fcompare_buffer_substrings): Likewise.
6736 * frame.h (struct terminal, struct font_driver_list):
6737 Remove redundant declarations.
6738 * window.h (Qleft, Qright): Likewise.
6740 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6742 Do not mark objects from deleted buffers, windows and frames.
6743 * alloc.c (mark_buffer): Mark just the buffer if it is dead.
6744 (mark_object): Likewise for windows and frames.
6746 2012-09-05 Dmitry Antipov <dmantipov@yandex.ru>
6748 * alloc.c (valid_lisp_object_p): Treat killed buffers,
6749 buffer_defaults and buffer_local_symbols as valid objects.
6750 Return special value to denote them.
6752 2012-09-05 Paul Eggert <eggert@cs.ucla.edu>
6754 * fileio.c, filelock.c, floatfns.c, fns.c: Use bool for boolean.
6755 * fileio.c (auto_saving, auto_save_error_occurred, make_temp_name)
6756 (Fexpand_file_name, barf_or_query_if_file_exists, Fcopy_file)
6757 (file_name_absolute_p, Fsubstitute_in_file_name):
6758 (check_executable, check_writable, Ffile_accessible_directory_p)
6759 (Fset_file_selinux_context, Fdefault_file_modes)
6760 (Finsert_file_contents, choose_write_coding_system)
6761 (Fwrite_region, build_annotations, a_write, e_write)
6763 * filelock.c (boot_time_initialized, get_boot_time)
6764 (get_boot_time_1, lock_file_1, within_one_second):
6765 * floatfns.c (in_float):
6766 * fns.c (concat, internal_equal, Frequire, base64_encode_1)
6767 (base64_decode_1, cmpfn_eql, cmpfn_user_defined)
6768 (sweep_weak_table, sweep_weak_hash_tables, secure_hash):
6769 * lisp.h (struct Lisp_Hash_Table.cmpfn):
6770 * window.c (compare_window_configurations):
6771 Use bool for booleans.
6772 * fileio.c (auto_saving_dir_umask, auto_saving_mode_bits)
6773 (Fdefault_file_modes): Now mode_t, not int, for modes.
6774 (Fdo_auto_save): Set a boolean to 1 rather than using ++.
6775 (internal_delete_file): Now returns void, not a (boolean) int,
6776 since nobody was looking at the return value.
6777 * lisp.h, window.h: Adjust to above API changes.
6779 * xdisp.c (set_message): Simplify and reindent last change.
6781 2012-09-05 Juanma Barranquero <lekktu@gmail.com>
6783 * makefile.w32-in ($(BLD)/sysdep.$(O)): Update dependencies.
6785 2012-09-04 Lars Ingebrigtsen <larsi@gnus.org>
6787 * eval.c (call_debugger): Make the function non-static so that we
6788 can call it from set_message.
6790 * xdisp.c (set_message): Implement the new variable `debug-on-message'.
6791 (syms_of_xdisp): Defvar it and `inhibit-debug-on-message'.
6793 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6795 Give more-useful info on a fatal error (Bug#12328).
6796 * alloc.c [ENABLE_CHECKING]: Do not include <execinfo.h>.
6797 (die) [ENABLE_CHECKING]: Call fatal_error_backtrace instead
6798 of doing the work ourselves.
6799 * emacs.c (fatal_error_signal): Let fatal_error_backtrace
6800 do most of the work.
6801 (fatal_error_backtrace): New function, taken from the guts
6802 of the old fatal_error_signal, but with a new option to output
6804 (shut_down_emacs) [!DOS_NT]: Use strsignal to give more-useful
6805 info about the signal than just its number.
6806 * lisp.h (fatal_error_backtrace, emacs_backtrace): New decls.
6807 * sysdep.c: Include <execinfo.h>
6808 (emacs_backtrace): New function, taken partly from the previous
6809 code of the 'die' function.
6810 (emacs_abort): Call fatal_error_backtrace rather than abort.
6812 2012-09-04 Stefan Monnier <monnier@iro.umontreal.ca>
6814 * lread.c (readevalloop): Call internal-macroexpand-for-load to perform
6815 eager (load-time) macro-expansion.
6816 * lisp.mk (lisp): Add macroexp.
6818 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6820 Simplify redefinition of 'abort' (Bug#12316).
6821 Do not try to redefine the 'abort' function. Instead, redo
6822 the code so that it calls 'emacs_abort' rather than 'abort'.
6823 This removes the need for the NO_ABORT configure-time macro
6824 and makes it easier to change the abort code to do a backtrace.
6825 * .gdbinit: Just stop at emacs_abort, not at w32_abort or abort.
6826 * emacs.c (abort) [!DOS_NT && !NO_ABORT]:
6827 Remove; sysdep.c's emacs_abort now takes its place.
6828 * lisp.h (emacs_abort): New decl. All calls from Emacs code to
6829 'abort' changed to use 'emacs_abort'.
6830 * msdos.c (dos_abort) [defined abort]: Remove; not used.
6831 (abort) [!defined abort]: Rename to ...
6832 (emacs_abort): ... new name.
6833 * sysdep.c (emacs_abort) [!HAVE_NTGUI]: New function, taking
6834 the place of the old 'abort' in emacs.c.
6835 * w32.c, w32fns.c (abort): Do not #undef.
6836 * w32.c (emacs_abort): Rename from w32_abort.
6838 2012-09-04 Eli Zaretskii <eliz@gnu.org>
6840 * w32uniscribe.c (uniscribe_shape): Reverse the sign of
6841 offsets[j].dv, since the y axis of the screen coordinates points
6842 down, while the y axis of the font definition coordinates points
6843 up. This fixes display of Arabic diacritics such as KASRA and
6844 KASRATAN. (Bug#11860)
6846 2012-09-04 Paul Eggert <eggert@cs.ucla.edu>
6848 Be more systematic about _setjmp vs setjmp.
6849 * alloc.c (test_setjmp, mark_stack):
6850 * image.c (PNG_LONGJMP) [PNG_LIBPNG_VER < 10500]:
6851 (PNG_JMPBUF) [! (PNG_LIBPNG_VER < 10500)]:
6852 (png_load, my_error_exit, jpeg_load):
6853 * process.c (send_process_trap, send_process):
6854 Uniformly prefer _setjmp and _longjmp to setjmp and longjmp.
6855 The underscored versions are up to 30x faster on some hosts.
6856 Formerly, the code used setjmp+longjmp sometimes and
6857 _setjmp+_longjmp at other times, with no particular reason to
6858 prefer setjmp+longjmp.
6860 2012-09-03 Paul Eggert <eggert@cs.ucla.edu>

6890 * dispextern.h, lisp.h: Reflect above API changes.
6891 * firstfile.c (dummy): Use the address of 'main', whose signature
6892 won't change, instead of the address of 'initialize', whose
6893 signature just changed from int to bool.
6894 * lisp.h (fatal_error_in_progress): New decl of boolean, moved here ...
6895 * msdos.c (fatal_error_in_progress): ... from here.
6896 * xdisp.c (redisplaying_p): Now a boolean. Set it to 1 instead
6898 (redisplay_internal, unwind_redisplay): Simply clear
6899 REDISPLAYING_P when unwinding, instead of saving its previous,
6900 always-false value and then restoring it.
6902 Clean up some extern decls.
6903 Mostly, this hoists extern decls out of .c files and into .h files.
6904 That way, we're more likely to catch errors if the interfaces change.
6905 * alloc.c [USE_GTK]: Include "gtkutil.h" so that we need not
6906 declare xg_mark_data.
6907 * dispextern.h (x_frame_parm_handlers):

6927 Remove now-redundant extern decls.
6928 * keyboard.c, keyboard.h (ignore_mouse_drag_p) [USE_GTK || HAVE_NS]:
6929 * xfaces.c (Qultra_light, Qreverse_oblique, Qreverse_italic):
6931 * xfaces.c: Remove unnecessary static decls.
6932 * xterm.c (updating_frame): Remove decl of nonexistent object.
6934 * Makefile.in (gl-stamp): Don't scan $(SOME_MACHINE_OBJECTS)
6935 when building globals.h, as the objects that are not built on
6936 this host are not needed to compile C files on this host.
6938 2012-09-02 Jan Djärv <jan.h.d@swipnet.se>
6940 * gtkutil.h: Remove prototype for x_wm_set_size_hint.

6969 Use bool for boolean.
6970 * intervals.h, lisp.h, systime.h: Reflect above API changes.

6988 2012-09-01 Eli Zaretskii <eliz@gnu.org>
6990 * w32uniscribe.c (uniscribe_shape): Handle correctly the case of
6991 more than one grapheme cluster passed to the shaper: compute the
6992 offset adjustment values separately for each cluster. (Bug#11860)
6994 * image.c: Restore mistakenly removed inclusion of w32.h. Without
6995 it, GCC doesn't see prototypes of w32_delayed_load, and complains
6996 about implicit conversions from integer to pointer.
6998 2012-09-01 Daniel Colascione <dancol@dancol.org>
7000 * w32fns.c (x_display_info_for_name): Prevent crash if w32 window
7001 system used too early.
7003 2012-09-01 Paul Eggert <eggert@cs.ucla.edu>

7054 window system declarations.
7056 * frame.h: Move common functions here: set_frame_menubar,
7057 x_set_window_size, x_sync, x_get_focus_frame,
7058 x_set_mouse_position, x_set_mouse_pixel_position,
7059 x_make_frame_visible, x_make_frame_invisible, x_iconify_frame,

7086 * lisp.h (mark_ttys): Remove prototype.
7087 * alloc.c (Fgarbage_collect): Remove redundant (and the only) call

7120 * lread.c (init_lread): For out-of-tree builds, only add the
7121 source directory's site-lisp dir to the load-path if it exists,
7122 consistent with in-tree builds. (Bug#12302)

7143 Handle click on close button as quit.
7145 * nsterm.h (EmacsDialogPanel): Make timer_fired BOOL.
7146 Add window_closed and button_values. Add void as return value for
7147 add(Button|String|Split). addButton takes int instead of Lisp_Object.
7148 Add process_dialog as new member.
7150 2012-08-28 Eli Zaretskii <eliz@gnu.org>
7152 * ralloc.c (free_bloc): Don't dereference a 'heap' structure if it

7282 (code_convert_string, code_convert_string_norecord)
7283 (Fset_coding_system_priority):
7284 * fileio.c (Finsert_file_contents):
7285 Use bool for booleans.
7286 * coding.h, lisp.h: Reflect above API changes.
7287 * coding.c: Remove unnecessary static function decls.
7288 (detect_coding): Use unsigned, not signed, to copy an unsigned field.
7289 (decode_coding, encode_coding, decode_coding_gap): Return 'void',
7290 not a boolean 'int', since callers never look at the return value.
7291 (ALLOC_CONVERSION_WORK_AREA): Assume caller returns 'void', not 'int'.
7292 * coding.h (decoding_buffer_size, encoding_buffer_size)
7293 (emacs_mule_string_char): Remove unused extern decls.
7294 (struct iso_2022_spec, struct coding_system):
7295 Use 'unsigned int : 1' for boolean fields, since there's more than one.
7296 (struct emacs_mule_spec): Remove unused field 'full_support'.
7297 All initializations removed.
7298 * cmds.c (internal_self_insert): Don't assume EMACS_INT fits in 'int'.
7300 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
7302 Fix spare memory change (Bug#12286).
7303 * alloc.c (mark_maybe_pointer): Handle MEM_TYPE_SPARE.
7304 (valid_lisp_object_p): Likewise.
7306 2012-08-27 Martin Rudalics <rudalics@gmx.at>
7308 * window.c (Fset_window_configuration): Record any window's old
7309 buffer if it's replaced (see Bug#8789). If the new current
7310 buffer doesn't appear in the selected window, go to its old
7313 2012-08-27 Dmitry Antipov <dmantipov@yandex.ru>
7315 Special MEM_TYPE_SPARE to denote reserved memory.
7316 * alloc.c (enum mem_type): New memory type.
7317 (refill_memory_reserve): Use new type for spare memory.
7318 This prevents live_cons_p and live_string_p from incorrect
7319 detection of uninitialized objects from spare memory as live.
7321 2012-08-26 Paul Eggert <eggert@cs.ucla.edu>
7324 * Makefile.in (.PHONY): versioclean -> versionclean.
7326 Remove unused external symbols.
7327 * data.c (Qcons, Qfloat, Qmisc, Qstring, Qvector):
7328 * window.c (Qwindow_valid_p, decode_valid_window):
7329 Now static, not extern.
7330 * data.c (Qinterval): Remove; unused.
7331 (syms_of_data): Do not define 'interval'.
7332 * lisp.h (Qinteger, Qstring, Qmisc, Qvector, Qfloat, Qcons):
7333 * window.h (decode_valid_window):
7336 * character.c, charset.c, chartab.c: Use bool for booleans.
7337 * character.c (lisp_string_width, string_count_byte8)
7338 (string_escape_byte8):
7339 * charset.c (charset_map_loaded, load_charset_map, read_hex):
7340 (load_charset_map_from_file, map_charset_chars)
7341 (Fdefine_charset_internal, define_charset_internal)
7342 (Fdeclare_equiv_charset, find_charsets_in_text)
7343 (Ffind_charset_region, char_charset, Fiso_charset):
7344 * chartab.c (sub_char_table_ref, sub_char_table_ref_and_range)
7345 (sub_char_table_set, sub_char_table_set_range)
7346 (char_table_set_range, optimize_sub_char_table)
7347 (map_sub_char_table):
7348 Use bool for boolean.
7349 * character.c (str_to_unibyte): Omit last boolean argument; it was
7350 always 0. All callers changed.
7351 * character.h, charset.h: Adjust to match previous changes.
7352 * character.h (char_printable_p): Remove decl of nonexistent function.
7353 * charset.h (struct charset): Members code_linear_p, iso_chars_96,
7354 ascii_compatible_p, supplementary_p, compact_codes_p, unified_p
7355 are all boolean, so make them single-bit bitfields.
7357 * lisp.h (ASET): Remove attempt to detect side effects.
7358 It was meant to be temporary and it often doesn't work,
7359 because when IDX has side effects the behavior of IDX==IDX
7360 is undefined. See Stefan Monnier in
7361 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00762.html>.
7363 2012-08-26 Barry OReilly <gundaetiapo@gmail.com> (tiny change)
7365 * lisp.h (functionp): New function (extracted from Ffunctionp).
7366 (FUNCTIONP): Use it.
7367 * eval.c (Ffunctionp): Use it.
7369 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
7371 * xgselect.c (xg_select): Use auto storage for the GPollFD buffer
7372 as that's faster and simpler than static storage. Don't bother
7373 with the g_main_context_query overhead if g_main_context_pending
7374 says no events are pending.
7375 (gfds, gfds_size): Remove these static vars.
7376 (xgselect_initialize): Remove; no longer needed.
7377 All uses and decls removed.
7379 * emacs.c (fatal_error_signal_hook): Remove.
7380 All uses removed. This leftover from old code was always 0.
7382 * casefiddle.c, casetab.c, category.c: Use bool for boolean.
7383 * casefiddle.c (casify_object, casify_region):
7384 * casetab.c (set_case_table):
7385 * category.c, category.h (word_boundary_p):
7386 * category.h (CHAR_HAS_CATEGORY):
7387 Use bool for booleans, instead of int.
7389 2012-08-25 Eli Zaretskii <eliz@gnu.org>
7391 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on $(GNU_LIB)/execinfo.h.
7393 2012-08-25 Paul Eggert <eggert@cs.ucla.edu>
7395 On assertion failure, print backtrace if available.
7396 * alloc.c [ENABLE_CHECKING]: Include <execinfo.h>.
7397 (die) [ENABLE_CHECKING]: Print a backtrace if available.
7398 * Makefile.in (LIB_EXECINFO): New macro.
7401 * bytecode.c, callint.c, callproc.c: Use bool for boolean.
7402 * bytecode.c (exec_byte_code):
7403 * callint.c (check_mark, Fcall_interactively):
7404 * callproc.c (Fcall_process, add_env, child_setup, getenv_internal_1)
7405 (getenv_internal, sync_process_alive, call_process_exited):
7406 * lisp.h (USE_SAFE_ALLOCA):
7407 Use bool for booleans, instead of int.
7408 * lisp.h, process.h: Adjust prototypes to match above changes.
7409 * callint.c (Fcall_interactively): Don't assume the mark's
7410 offset fits in 'int'.
7412 2012-08-24 Paul Eggert <eggert@cs.ucla.edu>
7414 * buffer.c, buffer.h: Use bool for boolean.
7415 * buffer.c (reset_buffer_local_variables)
7416 (buffer_lisp_local_variables, Fset_buffer_modified_p)
7417 (Frestore_buffer_modified_p, Fset_buffer_multibyte):
7418 (overlays_at, overlays_in, mouse_face_overlay_overlaps)
7419 (overlay_touches_p, overlay_strings, Foverlay_put)
7420 (report_overlay_modification, call_overlay_mod_hooks):
7421 (mmap_enlarge, mmap_set_vars):
7422 * buffer.h (buffer_has_overlays, uppercasep, lowercasep):
7423 Use bool for booleans, instead of int.
7424 * buffer.c (compact_buffer, mmap_free_1): Return void, not int,
7425 since the 1-or-0 return value is always ignored anyway.
7426 (mmap_initialized_p):
7427 * buffer.h (struct buffer_text.inhibit_shrinking): Now bool, not int.
7428 * buffer.h, lisp.h: Adjust prototypes to match above changes.
7430 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
7432 * bidi.c: Use bool for boolean.
7433 This is a bit more readable, and makes the text segment of bidi.o
7434 0.4% smaller on my platform (GCC 4.7.1 x86-64, Fedora 15).
7435 Presumably it's faster too.
7436 (bidi_initialized, bidi_ignore_explicit_marks_for_paragraph_level):
7438 (bidi_cache_find_level_change, bidi_cache_iterator_state)
7439 (bidi_unshelve_cache, bidi_init_it, bidi_count_bytes)
7440 (bidi_char_at_pos, bidi_fetch_char, bidi_paragraph_init)
7441 (bidi_explicit_dir_char, bidi_level_of_next_char)
7442 (bidi_find_other_level_edge, bidi_move_to_visually_next):
7443 Use bool for booleans, instead of int.
7444 * dispextern.h (bidi_init_it, bidi_paragraph_init)
7445 (bidi_unshelve_cache): Adjust decls to match code.
7447 2012-08-23 Martin Rudalics <rudalics@gmx.at>
7449 * keyboard.c (Fposn_at_x_y): Do not allow internal window as
7452 2012-08-23 Paul Eggert <eggert@cs.ucla.edu>
7454 * atimer.c, atimer.h (turn_on_atimers): Use bool for boolean.
7455 * atimer.h: Include <stdbool.h>.
7457 2012-08-22 Dan Nicolaescu <dann@gnu.org>
7459 * frame.h (FRAME_W32_P, FRAME_MSDOS_P, FRAME_NS_P): Change to
7460 compile time tests instead of run time tests on systems that do
7462 (FRAME_MAC_P): Remove leftover from deleted code.
7463 * frame.c (syms_of_frame): Remove leftover from deleted code.
7465 2012-08-22 Jan Djärv <jan.h.d@swipnet.se>
7467 * nsterm.m (insertText:): Don't clear modifiers if code is space.
7469 2012-08-22 Paul Eggert <eggert@cs.ucla.edu>
7471 * fontset.c (FONTSET_ADD): Return void, not Lisp_Object.
7472 Otherwise, the compiler complains about (A?B:C) where B is void
7473 and C is Lisp_Object. This fixes an incompatibility with Sun C 5.12.
7474 (fontset_add): Return void, for FONTSET_ADD.
7476 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7478 * alloc.c: Use bool for booleans.
7479 (gc_in_progress, abort_on_gc)
7480 (setjmp_tested_p) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
7481 (dont_register_blocks) [GC_MALLOC_CHECK]:
7482 (suppress_checking) [ENABLE_CHECKING]: Now bool, not int.
7483 (check_string_bytes, make_specified_string, memory_full)
7484 (live_string_p, live_cons_p, live_symbol_p, live_float_p)
7485 (live_misc_p, live_vector_p, live_buffer_p, mark_maybe_object)
7486 (mark_stack, valid_pointer_p, make_pure_string)
7487 (Fgarbage_collect, survives_gc_p, gc_sweep):
7488 Use bool for booleans, instead of int.
7489 (test_setjmp) [!GC_SAVE_REGISTERS_ON_STACK && !GC_SETJMP_WORKS]:
7490 Remove unused local.
7491 * alloc.c (PURE_POINTER_P):
7492 * lisp.h (STRING_MULTIBYTE): Document that it returns a boolean.
7493 * editfns.c (Fformat):
7494 * fileio.c (Fexpand_file_name, Fsubstitute_in_file_name)
7496 * fns.c (sweep_weak_table):
7497 * lisp.h (suppress_checking, push_message, survives_gc_p)
7498 (make_pure_string, gc_in_progress, abort_on_gc):
7499 * lread.c (readchar, read1):
7500 * print.c (Fprin1_to_string):
7501 * xdisp.c (push_message):
7502 Use bool for booleans affected directly or indirectly by
7505 Make recently-introduced setters macros.
7506 * fontset.c (set_fontset_id, set_fontset_name, set_fontset_ascii)
7507 (set_fontset_base, set_fontset_frame, set_fontset_nofont_face)
7508 (set_fontset_default, set_fontset_fallback): Rename from their
7509 upper-case counterparts, and make them functions rather than macros.
7510 This is more consistent with the other recently-introduced setters.
7511 These don't need to be inline, since they're local.
7513 2012-08-21 Jan Djärv <jan.h.d@swipnet.se>
7515 * nsterm.m (fd_handler:): Alloc and release a NSAutoreleasePool in
7516 the loop (Bug#12247).
7518 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7520 * lisp.h (vcopy): Use memcpy rather than our own loop.
7521 This fixes a performance regression introduced by the recent
7522 addition of vcopy. This means 'vcopy' will need to be modified
7523 for a copying collector, but that's OK. Also, tighten the
7524 checking in the assertion.
7526 2012-08-21 Eli Zaretskii <eliz@gnu.org>
7528 * w32uniscribe.c (uniscribe_shape): Fix producing gstring
7529 components for RTL text (Bug#11860). Adjust X-OFFSET of each
7530 non-base glyph for the width of the base character, according to
7531 what x_draw_composite_glyph_string_foreground expects.
7532 Generate WADJUST value according to composition_gstring_width's
7533 expectations, to produce correct width of the composed character.
7534 Reverse the sign of the DU offset produced by ScriptPlace.
7536 2012-08-21 Paul Eggert <eggert@cs.ucla.edu>
7538 * dbusbind.c (xd_remove_watch): Do not assume C99 comments.
7540 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
7542 Avoid direct writes to contents member of struct Lisp_Vector.
7543 * lisp.h (vcopy): New function to copy data into vector.
7544 * dispnew.c (Fframe_or_buffer_changed_p): Use AREF and ASET.
7545 * fns.c (Ffillarray): Use ASET.
7546 * keyboard.c (timer_check_2): Use AREF and ASET.
7547 (append_tool_bar_item, Frecent_keys): Use vcopy.
7548 * lread.c (read_vector): Use ASET.
7549 * msdos.c (Frecent_doskeys): Use vcopy.
7550 * xface.c (Finternal_copy_lisp_face): Use vcopy.
7551 (Finternal_merge_in_global_face): Use ASET and vcopy.
7552 * xfont.c (xfont_list_pattern): Likewise.
7554 2012-08-21 Martin Rudalics <rudalics@gmx.at>
7556 * window.c (Fwindow_point): For the selected window always return
7557 the position of its buffer's point.
7558 (Fset_window_point): For the selected window always go in its
7559 buffer to the specified position.
7561 2012-08-21 Dmitry Antipov <dmantipov@yandex.ru>
7563 Setter macros for fontsets.
7564 * fontset.c (SET_FONTSET_ID, SET_FONTSET_NAME, SET_FONTSET_ASCII)
7565 (SET_FONTSET_BASE, SET_FONTSET_FRAME, SET_FONTSET_NOFONT_FACE)
7566 (SET_FONTSET_DEFAULT, SET_FONTSET_FALLBACK): New macros.
7569 2012-08-20 Glenn Morris <rgm@gnu.org>
7571 * Makefile.in (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
7572 Don't assume that `ln -f' works.
7574 2012-08-20 Eli Zaretskii <eliz@gnu.org>
7576 * .gdbinit: Use "set $dummy = ..." to avoid warnings from GDB 7.5
7577 and later about non-assignments with no effect. See discussion at
7578 http://sourceware.org/ml/gdb-patches/2012-08/msg00518.html for
7581 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7583 Inline setter functions for Lisp_Objects slots of struct specbinding.
7584 * eval.c (set_specpdl_symbol, set_specpdl_old_value): New functions.
7587 2012-08-20 Martin Rudalics <rudalics@gmx.at>
7589 * window.c (select_window): Always make selected window's buffer
7592 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7594 Use AREF and ASET for docstrings of category tables.
7595 * category.h (CATEGORY_DOCSTRING): Use AREF.
7596 (SET_CATEGORY_DOCSTRING): Use ASET.
7597 * category.c (Fdefine_category): Use SET_CATEGORY_DOCSTRING.
7599 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7601 Inline setter functions for hash table members.
7602 * lisp.h (set_hash_key, set_hash_value, set_hash_next)
7603 (set_hash_hash, set_hash_index): Rename with _slot suffix.
7604 (set_hash_key_and_value, set_hash_index, set_hash_next)
7605 (set_hash_hash): New functions.
7606 * charset.c, fns.c: Adjust users.
7608 2012-08-20 Dmitry Antipov <dmantipov@yandex.ru>
7610 Inline getter and setter functions for per-buffer values.
7611 * buffer.h (per_buffer_default, set_per_buffer_default)
7612 (per_buffer_value, set_per_buffer_value): New functions.
7613 (PER_BUFFER_VALUE, PER_BUFFER_DEFAULT): Remove.
7614 * buffer.c, data.c: Adjust users.
7616 2012-08-20 Juanma Barranquero <lekktu@gmail.com>
7618 * makefile.w32-in ($(BLD)/vm-limit.$(O)): Update dependencies.
7620 2012-08-19 Paul Eggert <eggert@cs.ucla.edu>
7622 Rely on <config.h> + <unistd.h> to declare 'environ',
7623 as gnulib does this if the system doesn't.
7624 * callproc.c, editfns.c, process.c (environ) [!USE_CRT_DLL]:
7625 Remove declaration. MS-Windows declares it on stdlib.h which is
7626 included by conf_post.h.
7627 * emacs.c (environ) [DOUG_LEA_MALLOC]:
7628 * vm-limit.c (environ) [ORDINARY_LINK]: Remove decl.
7629 * vm-limit.c: Include <unistd.h>, for 'environ'.
7631 * unexaix.c, unexcoff.c: Include "mem-limits.h".
7632 (start_of_data): Remove decl; mem-limits.h provides it.
7634 * xdisp.c (handle_invisible_prop): Make it a bit faster
7635 and avoid a gcc -Wmaybe-uninitialized diagnostic.
7637 2012-08-19 Chong Yidong <cyd@gnu.org>
7639 * xdisp.c (handle_invisible_prop): Fix ellipses at overlay string
7642 2012-08-19 Andreas Schwab <schwab@linux-m68k.org>
7644 * .gdbinit: Use call instead of set when calling a function in the
7647 * data.c (set_internal): Don't use set_blv_found.
7648 (Fkill_local_variable): Likewise.
7650 2012-08-18 Alp Aker <alp.tekin.aker@gmail.com>
7652 * nsfont.m (ns_ascii_average_width): Ensure the string
7653 ascii_printable is initialized with a null-terminated character
7654 array. Otherwise, it can contain undesired extra characters.
7656 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
7658 port new setting code to Sun C 5.8 2005/10/13
7659 * chartab.c, lisp.h (char_table_set, char_table_set_range):
7660 Return void, not Lisp_Object. Otherwise, the compiler
7661 complains about (A?B:C) where B is void and C is Lisp_Object
7662 when compiling CHAR_TABLE_SET, due to the recent change to
7663 the API of sub_char_table_set_contents.
7665 2012-08-18 Chong Yidong <cyd@gnu.org>
7667 * xdisp.c (handle_invisible_prop): Obey TEXT_PROP_MEANS_INVISIBLE
7668 for the string case (Bug#3874).
7670 2012-08-18 Paul Eggert <eggert@cs.ucla.edu>
7672 * buffer.h (BSET): Remove (Bug#12215).
7673 Replace all uses with calls to new setter functions.

7701 * category.c (bset_category_table):
7702 * syntax.c (bset_syntax_table):
7703 New setter functions.
7705 * process.h (PSET): Remove (Bug#12215).
7706 Replace all uses with calls to new setter functions.
7707 Use INLINE_HEADER_BEGIN, INLINE_HEADER_END.
7708 (PROCESS_INLINE): New macro.
7709 (pset_childp): New setter function.
7710 (pset_gnutls_cred_type) [HAVE_GNUTLS]: New setter function.
7711 * process.c (PROCESS_INLINE):
7712 Define to EXTERN_INLINE, so that the corresponding functions
7713 are compiled into code.
7714 (pset_buffer, pset_command, pset_decode_coding_system)
7715 (pset_decoding_buf, pset_encode_coding_system)

8609 since it's used in non-static inline functions now.
8611 * xfaces.c (face_at_buffer_position, face_for_overlay_string):

8665 it easier to think about future improvements. See
8666 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.

9048 (fill_queue): Call w32_read_console_input instead of ReadConsoleInput.
9049 (w32_kbd_patch_key, key_event): Use the codepage returned by
9050 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.
9051 (key_event): use uChar.UnicodeChar only if
9052 w32_console_unicode_input is non-zero.
9054 * w32console.c: Include w32heap.h.

9079 * alloc.c (listn): Fix the order the arguments are consed onto the
9082 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
9083 enumeration constants, as PURE and HEAP are too general, and clash
9084 with other headers and sources, such as gmalloc.c and the
9085 MS-Windows system headers. All users changed.
9087 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
9089 Revert last save_excursion_save and save_excursion_restore changes.
9090 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

9100 2012-07-27 Paul Eggert <eggert@cs.ucla.edu>
9102 Improve GDB symbol export (Bug#12036).
9103 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
9104 arms of an 'if', not using conditional expressions; otherwise GDB
9105 complains about the types in the unevaluated arm when the argument
9106 is an integer literal.
9107 (xgetint): Simplify expression.
9108 * alloc.c (gdb_make_enums_visible): New constant. This ports to
9109 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
9110 Zaretskii in <http://bugs.gnu.org/12036#13>.
9111 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
9112 needed now that we have gdb_make_enums_visible.
9113 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
9114 (enum enum_USE_LSB_TAG):
9115 New enum types, packaging up enums that need to be exported to GDB.
9117 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
9119 Utility function to make a list from specified amount of objects.

9133 * xdisp.c (syms_of_xdisp): Likewise.
9134 * xfns.c (syms_of_xfns): Likewise.
9136 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
9138 Fast save_excursion_save and save_excursion_restore.
9139 * lisp.h (struct Lisp_Excursion): New data type.
9140 (PVEC_EXCURSION): New pseudovector type.
9141 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
9142 to deal with it. Adjust comments.
9143 (init_marker, attach_marker): New prototype.
9144 (unchain_marker): Adjust prototype.

9153 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
9155 Fix export of symbols to GDB (Bug#12036).
9156 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
9157 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
9158 emacs.c, as this is a more-suitable home. Had this been done earlier
9159 the fix for 12036 would have avoided some of the problems noted in
9160 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
9161 would have been more obvious.
9162 * emacs.c: Do not include <verify.h>; no longer needed.
9163 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
9164 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
9165 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
9166 Remove; now done in lisp.h.
9167 * lisp.h (PUBLISH_TO_GDB): New macro.
9168 (GCTYPEBITS, USE_LSB_TAG, CHECK_LISP_OBJECT_TYPE, enum pvec_type)
9169 (DATA_SEG_BITS): Use it.
9170 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
9171 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
9172 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
9173 not be usable in #if. This simplifies things.
9175 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
9177 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
9179 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
9181 Simplify export of symbols to GDB (Bug#12036).
9182 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
9183 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
9184 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
9185 Adjust to changes in lisp.h and emacs.c, by using
9186 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
9187 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
9188 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
9189 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
9190 instead of gdb_valbits.
9191 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
9192 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
9193 instead of gdb_array_mark_flag.
9194 (xboolvector): Get size from $->size, not $->header.size.
9195 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
9196 (xreload, hook-run, hookpost-run): Remove.
9197 * emacs.c: Include <verify.h>.
9198 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
9199 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
9201 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
9202 (gdb_USE_LSB_TAG): New enum constants.
9203 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
9204 Also define these as enum constants, so they're visible to GDB.
9205 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
9206 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
9207 as constants, so they're visible to GDB.
9208 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
9209 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
9210 Now enum constants, not macros, so they're visible to GDB.
9211 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
9212 more convenient now. All uses changed.
9213 (VALMASK) [USE_LSB_TAG]: Also define in this case.
9214 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
9216 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>

9221 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
9223 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
9224 add argument, tune behavior, and adjust all callers.
9226 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
9228 Use typedef for EMACS_INT, EMACS_UINT.
9229 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
9230 than macros. This simplifies debugging in the usual case, since
9231 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
9232 and it allows expressions involving EMACS_INT casts.
9233 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
9235 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>
9237 * nsterm.m (ns_read_socket): Return early if there is a modal

9243 that FOCUS-FRAME can be omitted.
9245 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
9247 Adjust buffer text indirection counters at the end of Fkill_buffer.
9248 * buffer.c (Fkill_buffer): Adjust indirection counters when the
9249 buffer is definitely dead. This should really fix an issue reported
9250 by Christoph Scholtes again. (Bug#12007).
9251 (init_buffer_once): Initialize indirection counters of
9252 buffer_defaults and buffer_local_symbols (for sanity and safety).
9254 2012-07-24 Eli Zaretskii <eliz@gnu.org>
9256 * xdisp.c (init_iterator): Don't compute dimensions of truncation
9257 and continuation glyphs on tooltip frames, leave them at zero.

9260 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
9262 Simplify copy_overlay.
9263 * buffer.c (copy_overlay): Simplify. Use build_marker.

9272 it signals an error when a tooltip frame is being created.
9274 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
9276 Cleanup miscellaneous objects allocation and initialization.

9283 (build_overlay): Add prototype.
9285 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
9287 Swap buffer text indirection counters in Fbuffer_swap_text.
9288 * buffer.c (Fbuffer_swap_text): Swap indirections too.
9289 This avoids crash reported by Christoph Scholtes at
9290 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
9292 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
9294 * nsmenu.m (Popdown_data): New struct.
9295 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
9297 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
9298 (initWithContentRect): Make imgView and contentView non-static
9299 and autorelease them. Also autorelease img and matrix (Bug#12005).
9300 (dealloc): Remove (Bug#12005).
9302 2012-07-22 Dmitry Antipov <dmantipov@yandex.ru>
9304 Adjust consing_since_gc when objects are explicitly freed.
9305 * alloc.c (GC_DEFAULT_THRESHOLD): New macro.
9306 (Fgarbage_collect): Use it. Change minimum to 1/10 of default.

9313 (live_buffer, set_marker_internal): New function.
9314 (Fset_marker, set_marker_restricted): Use set_marker_internal.

9317 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
9319 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
9320 as it's limited by the amount of memory, not by INT_MAX.
9322 2012-07-21 Eli Zaretskii <eliz@gnu.org>
9324 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
9325 in special-event-map. See the discussion at
9326 http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00417.html
9329 * w32menu.c (add_menu_item): Cast to ULONG_PTR when assigning
9330 info.dwItemData. Fixes crashes on 64-bit Windows.

9384 * font.c (font_open_by_name): Change 2nd and 3rd args to the only arg
9385 of type Lisp_Object to avoid redundant calls to make_unibyte_string.
9386 Adjust users accordingly.
9387 * font.h (font_open_by_name): Adjust prototype.

9405 * buffer.h (FOR_EACH_BUFFER): Rename from 'for_each_buffer'.
9406 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
9407 'for_each_per_buffer_object_at'.
9408 All uses changed. It's better to use upper-case for macros that
9409 cannot be implemented as functions, to give the reader a clue
9410 that they're special.
9412 2012-07-19 Stefan Monnier <monnier@iro.umontreal.ca>
9414 * alloc.c (Fgarbage_collect): Tweak docstring.

9455 * intervals.c (merge_interval_right, merge_interval_left):
9456 Do not zero out this interval if it is absorbed by its children,
9457 as this interval's total length doesn't change in that case. See
9458 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00403.html>.
9460 2012-07-18 Paul Eggert <eggert@cs.ucla.edu>
9462 * alloc.c (Fmake_bool_vector): Fix off-by-8 bug
9463 when invoking (make-bool-vector N t) and N is a positive
9464 multiple of 8 -- the last 8 bits were mistakenly cleared.
9466 Remove some struct layout assumptions in bool vectors.
9467 * alloc.c (bool_header_size): New constant.
9468 (header_size, word_size): Move earlier, as they're now used earlier.
9469 Use 'word_size' in a few more places, where it's appropriate.
9470 (Fmake_bool_vector, sweep_vectors): Don't assume that there is no
9471 padding before the data member of a bool vector.
9472 (sweep_vectors): Use PSEUDOVECTOR_TYPEP, in an eassert, rather
9473 than doing the check by hand with an abort ().
9475 2012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
9477 * eval.c (Fdefvar): Don't check constants since we only set the var if
9478 it's not yet defined anyway (bug#11904).
9480 * lisp.h (last_undo_boundary): Declare new var.
9481 * keyboard.c (command_loop_1): Set it.

9974 * w32menu.c (Fx_popup_dialog): Likewise.
9976 2012-07-11 Glenn Morris <rgm@gnu.org>
9978 * s/bsd-common.h, s/cygwin.h: No need to undefine INTERRUPT_INPUT,
9979 since nothing has defined it on these platforms.

9993 2012-07-11 John Wiegley <johnw@newartisans.com>
9995 * alloc.c (mark_memory): Guard the "no_address_safety_analysis"
9996 function attribute, so we only use it if it exists in the
9999 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
10001 Avoid call to strlen in fast_c_string_match_ignore_case.
10002 * search.c (fast_c_string_match_ignore_case): Change to use
10003 length argument. Adjust users accordingly.
10004 * lisp.h (fast_c_string_match_ignore_case): Adjust prototype.
10006 2012-07-11 Paul Eggert <eggert@cs.ucla.edu>

10023 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
10025 Avoid calls to strlen in font processing functions.
10026 * font.c (font_parse_name, font_parse_xlfd, font_parse_fcname)
10027 (font_open_by_name): Change to use length argument.

10045 2012-07-10 Paul Eggert <eggert@cs.ucla.edu>
10047 Remove "#define unix" that is no longer needed (Bug#11905).
10048 * s/aix4-2.h (unix): Remove; no longer needed.
10050 EMACS_TIME simplification (Bug#11875).
10051 This replaces macros (which typically do not work in GDB)
10052 with functions, typedefs and enums, making the code easier to debug.
10053 The functional style also makes code easier to read and maintain.
10054 * systime.h: Include <sys/time.h> on all hosts, not just if
10055 WINDOWSNT, since 'struct timeval' is needed in general.
10056 (EMACS_TIME): Now a typedef, not a macro.
10057 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
10059 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)
10060 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE, EMACS_TIME_EQ)

10064 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
10065 which are not functions. All uses rewritten to use:
10066 (make_emacs_time): New function.
10067 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
10068 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
10069 not functions. All uses rewritten to use the following, respectively:
10070 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
10071 (add_emacs_time, sub_emacs_time): New functions.
10072 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
10073 * fileio.c (Fcopy_file):
10074 * xterm.c (XTflash): Get the current time closer to when it's used.
10075 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.
10077 * bytecode.c (targets): Suppress -Woverride-init warnings.
10079 Simplify by avoiding confusing use of strncpy etc.
10080 * doc.c (Fsnarf_documentation):
10081 * fileio.c (Ffile_name_directory, Fsubstitute_in_file_name):
10082 * frame.c (Fmake_terminal_frame):
10083 * gtkutil.c (get_utf8_string):
10085 * nsmenu.m (ns_update_menubar):
10086 * regex.c (regerror):
10087 Prefer memcpy to strncpy and strncat when either will do.
10088 * fileio.c (Fsubstitute_in_file_name):
10089 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
10090 (menu_separator_name_p):
10091 * nsmenu.m (ns_update_menubar):
10092 Prefer memcmp to strncmp when either will do.
10093 * nsterm.m: Include <ftoastr.h>.
10095 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
10096 Prefer snprintf to strncpy.
10097 * nsterm.m (ns_term_init):
10098 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
10099 * nsterm.m (ns_term_init):
10100 Avoid the need for strncpy, by using build_string or
10101 make_unibyte_string directly. Use dtoastr, not snprintf.
10102 * process.c (Fmake_network_process): Diagnose service names that
10103 are too long, rather than silently truncating them or creating
10104 non-null-terminated names.
10105 (Fnetwork_interface_info): Likewise, for interface names.
10106 * sysdep.c (system_process_attributes) [GNU_LINUX]:
10107 Prefer sprintf to strncat.
10108 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
10109 Prefer vsnprintf to vsprintf + strncpy.
10111 2012-07-10 Glenn Morris <rgm@gnu.org>
10113 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
10114 Clarify fallback case.
10116 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
10118 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
10119 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
10120 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
10121 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
10122 where argument type is known to be a Lisp_Cons.
10124 2012-07-10 Tom Tromey <tromey@redhat.com>
10126 * bytecode.c (BYTE_CODE_THREADED): New macro.
10127 (BYTE_CODES): New macro. Replaces all old byte-code defines.
10128 (enum byte_code_op): New type.
10129 (CASE, NEXT, FIRST, CASE_DEFAULT, CASE_ABORT): New macros.
10130 (exec_byte_code): Use them. Use token threading when applicable.
10132 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
10134 Optimize pure C strings initialization.
10135 * lisp.h (make_pure_string): Fix prototype.
10136 (build_pure_c_string): New function, defined as static inline. This
10137 provides a better opportunity to optimize away calls to strlen when
10138 the function is called with compile-time constant argument.
10139 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
10140 argument, adjust users accordingly. Use build_pure_c_string where
10142 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
10143 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
10144 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
10146 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
10148 Avoid calls to strlen in miscellaneous functions.
10149 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
10150 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
10151 * lread.c (openp): Likewise.
10153 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
10155 Avoid calls to strlen in path processing functions.
10156 * fileio.c (file_name_as_directory): Add comment. Change to add
10157 srclen argument and return the length of result. Adjust users
10159 (directory_file_name): Fix comment. Change to add srclen argument,
10160 swap 1st and 2nd arguments to obey the common convention.
10161 Adjust users accordingly.
10162 * filelock.c (fill_in_lock_file_name): Avoid calls to strlen.
10164 2012-07-10 Glenn Morris <rgm@gnu.org>
10166 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/netbsd.h, s/unixware.h:
10167 Move PENDING_OUTPUT_COUNT definition to configure.
10169 * s/irix6-5.h (DATA_START, DATA_SEG_BITS):
10170 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
10171 * s/gnu.h (DATA_START): Move definitions to configure.
10173 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
10174 We include usg5-4-common.h, which defines them both.
10176 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
10177 O_RDONLY already includes it).
10179 Stop ns builds setting the EMACSLOADPATH environment variable.
10180 * nsterm.m (ns_load_path): Rename from ns_init_paths.
10181 Now it does not set EMACSLOADPATH, just returns the load-path string.
10182 * nsterm.h: Update accordingly.
10183 * lread.c [HAVE_NS]: Include nsterm.h.
10184 (init_lread) [HAVE_NS]: Use ns_load_path.
10185 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
10187 2012-07-09 Glenn Morris <rgm@gnu.org>
10189 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
10190 since the included bsd-common.h does so.
10192 Stop ns builds setting the EMACSPATH environment variable.
10193 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
10194 (ns_init_paths): Do not set EMACSPATH.
10195 * nsterm.h (ns_exec_path): Add it.
10196 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
10199 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
10201 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
10203 * process.c (wait_reading_process_output): 'waitchannels' was unset
10204 when read_kbd || !NILP (wait_for_cell); fix this.
10206 Add GCC-style 'const' attribute to functions that can use it.
10207 * character.h (char_resolve_modifier_mask):
10208 * keyboard.h (make_ctrl_char):
10209 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
10210 (init_character_once, next_almost_prime, init_fns, init_image)
10211 (flush_pending_output, init_sound):
10212 * mem-limits.h (start_of_data):
10213 * menu.h (finish_menu_items):
10214 Add ATTRIBUTE_CONST.
10215 * emacs.c (DEFINE_DUMMY_FUNCTION):
10216 Declare the dummy function with ATTRIBUTE_CONST.
10217 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
10218 Add decls with ATTRIBUTE_CONST.
10220 Minor improvements to make_formatted_string.
10221 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
10222 where int is good enough, as vsprintf returns an int.
10223 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
10225 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
10227 Use make_formatted_string to avoid double length calculation.
10228 * lisp.h (make_formatted_string): New prototype.
10229 * alloc.c (make_formatted_string): New function.
10230 * buffer.c (Fgenerate_new_buffer_name): Use it.
10231 * dbusbind.c (syms_of_dbusbind): Likewise.
10232 * editfns.c (Fcurrent_time_zone): Likewise.
10233 * filelock.c (get_boot_time): Likewise.
10234 * frame.c (make_terminal_frame, set_term_frame_name)
10235 (x_report_frame_params): Likewise.
10236 * image.c (gs_load): Likewise.
10237 * minibuf.c (get_minibuffer): Likewise.
10238 * msdos.c (dos_set_window_size): Likewise.
10239 * process.c (make_process): Likewise.
10240 * xdisp.c (ensure_echo_area_buffers): Likewise.
10241 * xsettings.c (apply_xft_settings): Likewise.
10243 2012-07-09 Glenn Morris <rgm@gnu.org>
10245 Stop ns builds polluting the environment with EMACSDATA, EMACSDOC.
10246 * nsterm.m (ns_etc_directory): New function, split from ns_init_paths.
10247 (ns_init_paths): Do not set EMACSDATA, EMACSDOC.
10248 * nsterm.h (ns_etc_directory): Add it.
10249 * callproc.c [HAVE_NS]: Include nsterm.h.
10250 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
10252 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
10254 Move marker debugging code under MARKER_DEBUG.
10255 * marker.c (MARKER_DEBUG): Move marker debugging code under
10256 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
10257 for bootstrap with --enable-checking (~3x slowdown reported
10258 by Juanma Barranquero <lekktu@gmail.com>).
10259 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
10261 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
10263 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
10264 See <http://bugs.gnu.org/11825#29>.
10266 2012-07-08 Eli Zaretskii <eliz@gnu.org>
10268 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
10269 has no font, use the frame's font. (Bug#11813)
10270 (display_line): Add commentary about displaying truncation glyphs
10272 (produce_special_glyphs): Move here from term.c.
10274 * term.c (produce_special_glyphs): Move to xdisp.c.
10276 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
10279 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
10281 * xdisp.c (display_line): Avoid warning about implicit declaration
10284 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
10286 * lisp.h: Remove empty conditional.
10288 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
10290 * lread.c (load_path_check): Now static.
10292 Fix some minor --with-ns problems found by static checking.
10293 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
10294 (x_set_font) [!HAVE_X_WINDOWS]:
10295 * image.c (xpm_load_image) [HAVE_NS]:
10296 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
10297 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
10298 Remove unused local.
10299 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
10300 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
10301 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
10302 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
10303 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
10304 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
10305 Fix pointer signedness problem.
10306 * xfaces.c (FRAME_X_FONT_TABLE):
10307 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
10309 2012-07-07 Glenn Morris <rgm@gnu.org>
10311 * lread.c (load_path_check): New function, split from init_lread.
10312 (init_lread): Reorganize. Motivation:
10313 If EMACSLOADPATH is set, check/warn about that rather than the
10314 defaults, which we are not going to use. Hence we can remove
10315 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
10316 Don't warn if site-lisp directories are missing.
10317 If not installed, start from a blank load-path, since
10318 PATH_LOADSEARCH refers to the eventual installation directories.
10320 2012-07-07 Eli Zaretskii <eliz@gnu.org>
10322 Support truncation and continuation glyphs on GUI frames, when
10323 fringes are disabled. (Bug#11832)
10324 * xdisp.c (init_iterator): Get dimensions of truncation and
10325 continuation glyphs even if on GUI frames.
10326 Adjust it->last_visible_x on GUI frames when the left or right fringes,
10327 or both, are absent.
10328 (start_display, move_it_in_display_line_to): Handle the case of a
10329 GUI frame without a fringe to display continuation or truncation
10331 (insert_left_trunc_glyphs): Support GUI frames: make sure
10332 truncation glyphs overwrite enough glyphs from the current line to
10333 have sufficient space in pixels.
10334 (display_line): Support truncation and continuation glyphs on GUI
10335 frames. If some spare pixels are left on the line after inserting
10336 the truncation glyphs, fill that space with a stretch glyph of a
10337 suitably computed width.
10339 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
10340 produce_glyphs, to support GUI sessions.
10342 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
10344 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
10346 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
10348 Do not require float-time's arg to fit in time_t (Bug#11825).
10349 This works better on hosts where time_t is unsigned, and where
10350 float-time is applied to the (negative) difference between two times.
10351 * editfns.c (decode_time_components): Last arg is now double *,
10352 not int *, and means to store all the result as a double, without
10353 worrying about whether the seconds part fits in time_t.
10354 All callers changed.
10355 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
10356 All callers changed.
10357 (Ffloat_time): Do not fail merely because the specified time falls
10358 outside of time_t range.
10360 2012-07-07 Glenn Morris <rgm@gnu.org>
10362 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

10393 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
10394 Eli Zaretskii <eliz@gnu.org>
10396 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.

10398 Obsolete settings removed.
10400 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10402 * process.c: Avoid unnecessary calls to gettime.
10403 (wait_reading_process_output): Don't get the time of day
10404 when gobbling data immediately and not waiting, as there's no need
10405 for it in that case. This removes a FIXME.
10407 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
10409 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
10410 is defined (Bug#11768).

10418 Call byte_char_debug_check with correct arguments.
10420 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10422 Compile marker debugging code only if ENABLE_CHECKING is defined.
10423 * marker.c (byte_char_debug_check, count_markers):
10424 Use only if ENABLE_CHECKING is defined.
10425 (byte_debug_flag): Remove.
10426 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
10427 Always call byte_char_debug_check if ENABLE_CHECKING is defined.

10457 * window.c (save_window_save): Likewise.
10459 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
10461 Do not use Fdelete_overlay in delete_all_overlays
10462 to avoid redundant calls to unchain_overlay.
10463 * buffer.c (drop_overlay): New function.
10464 (delete_all_overlays, Fdelete_overlay): Use it.
10465 * minibuf.c (get_minibuffer): Fix comment.
10467 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
10469 Port to OpenBSD 5.1 amd64.
10470 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
10471 This is needed for OpenBSD, and should be harmless on all BSD systems.
10472 Also, include <sys/sysctl.h>, as it should be available on all
10473 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
10474 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
10475 use p_pid member, not kp_proc.pid.
10477 2012-07-06 Glenn Morris <rgm@gnu.org>
10479 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
10481 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
10483 More xmalloc and related cleanup.

10492 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
10494 Omit needless casts involving void * pointers and allocation.
10495 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
10496 as the former is more robust if P's type is changed.
10497 Prefer xzalloc to xmalloc + memset 0.
10498 Simplify malloc-or-realloc to realloc.
10499 Don't worry about xmalloc returning a null pointer.
10500 Prefer xstrdup to xmalloc + strcpy.

10508 * xdisp.c (display_line): Fix horizontal pixel coordinates when
10509 hscroll is larger than the line width. Fixes long and futile
10510 looping inside extend_face_to_end_of_line (on a TTY) producing
10511 glyphs that are not needed and thrown away.
10513 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
10515 * marker.c (set_marker_restricted_both): Simplify by using
10518 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
10520 * editfns.c (region_limit): Simplify by using clip_to_bounds.

10529 followed by gtk_box_set_homogeneous (Bug#11768).
10530 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
10531 (update_theme_scrollbar_width, xg_create_scroll_bar):
10532 Use gtk_scrollbar_new (Bug#11768).

10534 (is_box_type): New function (Bug#11768).
10535 (xg_tool_item_stale_p): Call is_box_type.
10536 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
10537 with default display (Bug#11768).
10539 2012-07-05 Eli Zaretskii <eliz@gnu.org>
10541 * xdisp.c (window_hscroll_limited): New function.
10542 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
10543 coordinates when window's hscroll is set to insanely large
10544 values. (Bug#11857)
10546 2012-07-05 Juanma Barranquero <lekktu@gmail.com>

10610 Problem reported by Troels Nielsen in
10611 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
10613 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10615 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
10616 This should be fixed in a better way; see Eli Zaretskii in
10617 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
10618 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
10620 * fileio.c (time_error_value): Rename from special_mtime.
10621 The old name's problems were noted by Eli Zaretskii in
10622 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
10624 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
10625 This variable's comment says Emacs needs at least one GDB-visible
10626 symbol of type enum pvec_type, to work around GDB problems.
10627 The symbol's value doesn't matter.
10629 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
10630 that causes compilation to fail on pre-C99 compilers.
10632 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
10634 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)

10658 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
10659 (sweep_vectors): Use it. Use local var `total_bytes' instead of
10660 abusing vector->header.next.nbytes.
10661 (live_vector_p): Use PVEC_TYPE.
10662 (mark_object): Adapt code to extract pvectype. Use switch.
10664 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>

10671 Fix compilation with --enable-gcc-warnings and -O1
10672 optimization level.

10674 to avoid compiler warning. Add eassert.
10675 * search.c (simple_search): Initialize match_byte to avoid
10676 compiler warning. Add eassert.
10678 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10680 Avoid weird behavior with large horizontal scrolls.
10681 Without this change, for example, large hscroll values would
10682 mess up Emacs's display on Fedora 15 x86, presumably due to
10683 overflows in int calculations in the display code.
10684 Also, if buffers had long lines, Emacs would freeze.
10685 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
10686 (set_window_hscroll): New function, containing the old guts of
10687 Fset_window_hscroll. Return the clipped value.
10688 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
10689 This avoids the need to check against PTRDIFF_MAX.
10691 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
10693 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>

10697 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
10699 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
10700 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
10701 since GCC 4.4.6 issues a bogus warning for them.
10703 Fix bugs in file timestamp newness comparisons.
10704 * fileio.c (Ffile_newer_than_file_p):
10705 * lread.c (Fload): Use full timestamp resolution of files,
10706 not just the 1-second resolution, so that files that are only
10707 slightly newer still count as newer.
10708 * fileio.c (Ffile_newer_than_file_p): Don't assume file
10709 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
10711 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
10713 * fileio.c: Improve handling of file time marker. (Bug#11852)

10720 * fileio.c (Finsert_file_contents): Properly handle st_mtime
10721 marker for non-existing file. (Bug#11852)
10723 2012-07-03 Glenn Morris <rgm@gnu.org>
10725 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
10726 and did not make it into globals.h).
10728 2012-07-03 Tom Tromey <tromey@redhat.com>

10775 values which aren't power of 2.
10776 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
10777 Verify its value and the value of VECTOR_BLOCK_SIZE. Adjust users

10784 * alloc.c (mark_object): Revert part of last patch to use `switch'.
10786 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10788 * alloc.c (allocate_vector_block): Remove redundant
10789 calls to mallopt if DOUG_LEA_MALLOC is defined.
10790 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
10791 avoid calls to mallopt if zero_vector is returned.
10793 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10795 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
10796 is enabled, avoid dereferencing NULL current_sblock if
10799 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
10801 Cleanup basic buffer management.
10802 * buffer.h (struct buffer): Change layout to use generic vector
10803 marking code. Fix some comments. Change type of 'clip_changed'
10804 to bitfield. Remove unused #ifndef old.
10805 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
10806 (GET_OVERLAYS_AT): Fix indentation.
10807 (for_each_per_buffer_object_at): New macro.
10808 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
10809 (Fbuffer_local_variables): Use it.
10810 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
10811 * alloc.c (allocate_buffer): Adjust to match new layout of
10812 struct buffer. Fix comment.
10813 (mark_overlay): New function.
10814 (mark_buffer): Use it. Use mark_vectorlike to mark normal
10815 Lisp area of struct buffer.
10816 (mark_object): Use it. Adjust marking of misc objects
10817 and related comments.
10819 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
10821 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
10822 wrapper that is not needed because the wrapped code is a no-op (zero
10823 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
10824 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
10826 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
10828 * alloc.c (mark_buffer): Simplify. Remove prototype.
10829 (mark_object): Add comment. Reorganize marking of vector-like
10830 objects. Use CHECK_LIVE for all vector-like objects except buffers
10831 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
10832 Avoid redundant calls to mark_vectorlike for bool vectors.
10834 2012-06-30 Glenn Morris <rgm@gnu.org>
10836 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
10838 * epaths.in (PATH_SITELOADSEARCH): New.
10839 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
10840 This is rather than relying on --enable-locallisppath elements
10841 having "site-lisp" in their names. (Bug#10208#25, 11658)
10843 2012-06-30 Eli Zaretskii <eliz@gnu.org>
10845 * w32proc.c (sys_select): Accept and ignore one more argument.
10847 * w32.c (emacs_gnutls_pull): Call select with one more argument.
10849 * sysselect.h [DOS_NT]: Don't include sys/select.h.
10850 (pselect) [!MS_DOS]: Redirect to sys_select.
10852 * sysdep.c: Don't include dos.h and dosfns.h.
10854 * process.c (sys_select):
10855 * msdos.c (sys_select): Accept one more argument and ignore it.
10857 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
10858 adapt data types and code to that.
10861 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
10862 which clashes with the gnulib function of the same name.
10864 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
10866 * font.c (font_style_to_value, font_style_symbolic)
10867 (font_prop_validate_style): Add type checks for values in
10870 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
10872 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
10875 2012-06-29 Eli Zaretskii <eliz@gnu.org>
10877 * xdisp.c (try_window_id): Undo last change.
10879 * w32.c (getwd): Adjust commentary about startup_dir.
10880 (init_environment): Always call sys_access, even in non-MSVC
10881 builds. Don't chdir to the directory of the Emacs executable.
10882 This undoes code from 1997 which was justified by the need to
10883 "avoid conflicts when removing and renaming directories". But its
10884 downside was that every relative file name was being interpreted
10885 relative to the directory of the Emacs executable, which can never
10886 be TRT. In particular, it broke sys_access when called with
10887 relative file names.
10888 (sys_access): Map GetLastError to errno.
10890 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>

10896 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
10899 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
10901 * gnutls.c (emacs_gnutls_handshake):
10902 Add QUIT to make the loop interruptible.
10904 2012-06-29 Glenn Morris <rgm@gnu.org>
10906 * charset.c (init_charset): Make lack of etc/charsets fatal.

10914 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
10915 undefined. Convert from xassert to eassert.

10917 * nsterm.m: Likewise.
10919 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>

10925 Avoid integer overflow on scroll-left and scroll-right.
10926 * window.c (HSCROLL_MAX): New macro.
10927 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
10928 overflow when requested scroll falls outside ptrdiff_t range.
10930 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
10932 * window.h (struct window): Change type of 'hscroll',
10933 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
10934 'last_modified' and 'last_overlay_modified' to EMACS_INT.
10935 Adjust users accordingly.
10936 * xdisp.c (try_cursor_movement): Replace type check with eassert.
10937 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
10938 from EMACS_INT to ptrdiff_t.
10939 (make_window): Omit redundant initialization.

10957 enabled with --enable-checking=[all,glyphs] configure option.
10958 Fix GLYPH_DEBUG usage assuming that it may be undefined,
10959 adjust comments accordingly.

11008 * alloc.c (allocate_string_data): Remove dead code.
11009 * xsettings.c (XSETTINGS_FONT_NAME): Move under HAVE_XFT to
11010 avoid GCC warning about unused macro.
11012 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
11014 * alloc.c (allocate_string): Omit intervals initialization.
11015 * alloc.c (make_uninit_multibyte_string): Initialize intervals

11041 when building with Clang.

11070 2012-06-26 Dmitry Antipov <dmantipov@yandex.ru>
11072 * alloc.c: Remove build_string.
11073 * lisp.h: Define build_string as static inline. This provides
11074 a better opportunity to optimize away calls to strlen when the
11075 function is called with compile-time constant argument.
11076 * image.c (imagemagick_error): Convert to build_string.
11077 * w32proc.c (sys_spawnve): Likewise.
11078 * xterm.c (x_term_init): Likewise.
11080 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
11082 Use sprintf return value instead of invoking strlen on result.
11083 In the old days this wasn't portable, since some sprintf
11084 implementations returned char *. But they died out years ago and
11085 Emacs already assumes sprintf returns int.
11086 Similarly for float_to_string.
11087 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

11092 * print.c (print_object):
11093 * xdisp.c (message_dolog):
11094 * xfns.c (syms_of_xfns):
11095 Use sprintf or float_to_string result to avoid need to call strlen.
11096 * data.c (Fnumber_to_string):
11097 Use make_unibyte_string, since the string must be ASCII.
11098 * lisp.h, print.c (float_to_string): Now returns int length.
11099 * term.c (produce_glyphless_glyph):
11100 Use sprintf result rather than recomputing it.
11102 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
11103 * Makefile.in (ALL_CFLAGS):
11104 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
11105 * gmalloc.c, regex.c: Include <config.h> unconditionally.
11107 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
11109 * dispextern.h (xstrcasecmp): Define to library function
11110 strcasecmp if available.

11128 * gtkutil.c (get_utf8_string): Remove redundant assignment.
11129 sprintf already null-terminates its output.
11131 * xfns.c (x_window): Remove redundant cast.
11133 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
11135 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
11136 `const char *' to `char *' to avoid compiler warning.
11138 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
11140 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
11141 instead of truncating it to 63 (admittedly a generous limit).
11143 * process.c: Fix spelling and caps in comments.
11145 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>
11147 * emacs.c (setpgrp): Remove definition, unused.

11157 (SYSTIME_H): Add nt/inc/sys/time.h.
11159 * systime.h [WINDOWSNT]: Include sys/time.h.
11161 * s/ms-w32.h (struct timespec): Definition moved from
11162 nt/inc/sys/time.h. Suggested by Paul Eggert <eggert@cs.ucla.edu>.

11192 No need for separate decl merely because of _Noreturn.
11193 * sound.c (sound_warning, parse_sound):
11194 Remove unnecessary forward decls.
11196 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
11198 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
11199 * lisp.h (WAIT_READING_MAX): New macro.
11200 * dispnew.c (Fsleep_for, sit_for):
11201 * keyboard.c (kbd_buffer_get_event):
11202 * process.c (Faccept_process_output):
11203 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
11204 This improves on the previous patch, which introduced a bug
11205 when time_t is unsigned and as wide as intmax_t.
11206 See <http://bugs.gnu.org/9000#51>.
11208 2012-06-23 Eli Zaretskii <eliz@gnu.org>

11222 2012-06-23 Paul Eggert <eggert@cs.ucla.edu>
11224 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
11225 Privately reported by Herbert J. Skuhra.
11226 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
11228 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
11229 not make_lisp_timeval, when the argument is of type EMACS_TIME.
11231 2012-06-23 Eli Zaretskii <eliz@gnu.org>
11233 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
11234 last argument of make_unibyte_string.
11236 * keyboard.c (kbd_buffer_get_event): Include the codepage and the
11237 language ID in the event parameters.
11239 * w32term.c (w32_read_socket): Put the new keyboard codepage into
11240 event.code, not the obscure "character set ID".
11242 2012-06-23 Chong Yidong <cyd@gnu.org>
11244 * xmenu.c (x_menu_wait_for_event): Adapt GTK3 to new xg_select.

11248 Fix the MS-Windows build broken by 2012-06-22T21:17:42Z!eggert@cs.ucla.edu.
11249 * w32.c (fdutimens): New function.
11251 * w32proc.c (sys_select): Adapt to change in the EMACS_TIME type.
11253 * s/ms-w32.h (pselect): Redirect to sys_select.
11255 * sysselect.h [WINDOWSNT]: Don't include sys/select.h.
11257 * ralloc.c (r_alloc_inhibit_buffer_relocation): Fix stupid thinko
11258 in the logic of incrementing and decrementing the value of
11259 use_relocatable_buffers.

11263 * sysdep.c [__FreeBSD__]: Fix recently-introduced typos.

11267 (TIMEVAL) [__FreeBSD__]: Now a static function rather than a macro.
11268 (TIMEVAL, system_process_attributes) [__FreeBSD__]:

11273 Support higher-resolution time stamps (Bug#9000).
11274 The time stamps are only nanosecond-resolution at the C level,
11275 since that's the best that any real-world system supports now.
11276 But they are picosecond-resolution at the Lisp level, as that's

11286 now provides it if it's absent.
11287 (start_atimer): Port to higher-res time stamps.
11288 Check for time stamp overflow. Don't get current time more
11289 often than is needed.

11342 (timer_check_2): Use it.
11344 * nsterm.m (select_timeout, timeval_subtract): Remove.
11345 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,

11348 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
11349 * nsterm.h (ns_select): Adjust prototype.

11369 Check for time stamp overflow. Do not assume time_t is signed.
11370 (select_wrapper): Remove; we now use pselect.
11371 (Fprocess_attributes): Now generates ns-resolution time stamps.
11373 * sysdep.c: Include utimens.h. Don't include utime.h
11374 or worry about struct utimbuf; gnulib does that for us now.
11375 (gettimeofday): Remove; gnulib provides a substitute.
11376 (make_timeval): New function.
11377 (set_file_times): Now sets ns-resolution time stamps.
11378 New arg FD; all uses changed.

11385 provides a substitute now.
11387 * systime.h: Include timespec.h rather than sys/time.h and time.h,
11388 since it guarantees struct timespec.
11389 (EMACS_TIME): Now struct timespec, so that we can support
11390 ns-resolution time stamps.
11391 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
11392 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
11393 (EMACS_USECS): Remove.
11394 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
11395 so multiply the arg by 1000 before storing it.
11396 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
11398 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):

11405 (make_timeval, make_lisp_time, decode_time_components): New decls.
11406 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in

11408 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
11409 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.

11427 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
11428 for compatibility with pselect. Support ns-resolution time stamps.

11432 * xselect.c (wait_for_property_change, x_get_foreign_selection):
11433 Check for time stamp overflow, and support ns-resolution time stamps.

11437 (timeval_subtract): Remove; no longer needed.
11438 (XTflash, XTring_bell, x_wait_for_event):
11439 Port to ns-resolution time stamps. Don't assume time_t is signed.

11445 2012-06-22 Eli Zaretskii <eliz@gnu.org>
11447 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
11448 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
11449 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
11450 staticidx goes up to 1597 out of 1600 = 0x640.)
11452 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
11454 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.

11500 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
11501 gets killed during executing of this function (Bug#11665).
11502 Try to always return Qt when the buffer has been actually killed.
11503 (Vkill_buffer_query_functions): In doc-string say that functions
11504 run by this hook should not change the current buffer.

11528 * lisp.h (eassert): Assume C89 or later.
11529 This removes the need for CHECK.
11530 (CHECK): Remove. Its comments about always evaluating its
11531 argument were confusing, as 'eassert' typically does not evaluate
11534 * coding.c (produce_chars): Use ptrdiff_t, not int.
11536 * xterm.c (x_draw_underwave): Check for integer overflow.
11537 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

11719 USE_LSB_TAG now is always defined to be either 0 or 1.
11721 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
11722 code works fine either way, and efficiency is not a concern here,
11723 as the union type is for debugging, not for production.
11724 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
11725 Use an inline function on all platforms when using the union type,
11726 since this is simpler and 'static inline' can be used portably
11728 (LISP_INITIALLY_ZERO): New macro.
11729 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
11730 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.

11757 * s/gnu-kfreebsd.h, s/gnu-linux.h, s/gnu.h, s/hpux10-20.h:
11758 * s/irix6-5.h, s/ms-w32.h, s/msdos.h, s/template.h:
11759 * s/usg5-4-common.h: Move SYSTEM_TYPE to configure.
11761 2012-06-11 Stefan Monnier <monnier@iro.umontreal.ca>
11763 * alloc.c (make_byte_code): New function.

11819 * dispnew.c (showing_window_margins_p): Undo last change, which
11820 was done due to an inadvertent commit.
11821 (adjust_frame_glyphs_for_frame_redisplay): Do call

11832 * dispnew.c (showing_window_margins_p): Wrap in #if 0 to prevent unused
11833 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
11835 2012-06-08 Eli Zaretskii <eliz@gnu.org>
11837 * alloc.c (allocate_vectorlike): Fix last change.
11839 2012-06-08 Dmitry Antipov <dmantipov@yandex.ru>
11841 Block-based vector allocation of small vectors.
11842 * lisp.h (struct vectorlike_header): New field `nbytes',
11843 adjust comment accordingly.
11844 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'
11845 to denote vector blocks. Adjust users (live_vector_p,
11846 mark_maybe_pointer, valid_lisp_object_p) accordingly.

11868 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
11870 * doprnt.c (doprnt): Truncate multibyte char correctly.
11871 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
11872 would mishandle a string argument "Xc" if X was a multibyte
11873 character of length 2: it would truncate after X's first byte
11874 rather than including all of X.
11876 2012-06-06 Chong Yidong <cyd@gnu.org>
11878 * buffer.c (word_wrap): Doc fix.
11880 2012-06-04 Paul Eggert <eggert@cs.ucla.edu>

11909 Fbuffer_local_value; can return Qunbound.
11910 (Fbuffer_local_value): Use it.

11925 * minibuf.c (Fassoc_string): Remove duplicate declaration.
11927 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
11928 Convert pctcpu and pctmem to Lisp float properly.
11929 Let the compiler fold better, as 100.0/0x8000 is exact.
11931 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
11933 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
11936 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>

11940 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
11942 For a 'struct window', replace some Lisp_Object fields to
11943 bitfields where appropriate, remove unused fields.
11944 * window.h (struct window): Remove unused 'last_mark_x' and
11945 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
11946 change its type from Lisp_Object to bitfield.
11947 Change type of 'force_start', 'optional_new_start',
11948 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
11949 fields from Lisp_Object to bitfield. Adjust users accordingly.
11951 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
11953 Pacify gcc -Wdouble-precision when using Xaw.
11954 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
11955 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
11956 Use 'float' consistently, rather than 'float' in most places
11957 and 'double' in a couple of places.
11959 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11961 * xdisp.c (handle_stop): Detect whether we have overlay strings
11962 loaded by testing it->current.overlay_string_index to be
11963 non-negative, instead of checking whether n_overlay_strings is
11964 positive. (Bug#11587)
11966 2012-05-31 Chong Yidong <cyd@gnu.org>
11968 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).

11972 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11974 * search.c (search_buffer): Remove calls to
11975 r_alloc_inhibit_buffer_relocation, as it is now called by
11976 maybe_unify_char, which was the cause of relocation of buffer text
11979 2012-05-31 Eli Zaretskii <eliz@gnu.org>
11981 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
11982 for the duration of call to load_charset, to avoid problems with
11983 callers of maybe_unify_char that access buffer text through C
11986 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
11987 decrement the inhibition flag, instead of just setting or
11990 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
11992 Remove obsolete '#define static' cruft.
11993 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
11994 This #undef was "temporary" in 2000; it is no longer needed
11995 now that '#define static' has gone away.
11996 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
11997 (gray_bitmap_bits): Remove; no longer needed.
11998 All uses replaced with definiens.

12004 The following changes affect the code only when profiling.
12005 * dispnew.c (__executable_start): Rename from safe_bcopy.
12006 Define only on platforms that need it.
12007 * emacs.c: Include <sys/gmon.h> when profiling.
12008 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
12009 (__executable_start): Remove decl, since lisp.h does it now.
12010 (safe_bcopy): Remove decl; no longer has that name.
12011 (main): Coalesce #if into single bit of code, for simplicity.
12012 Cast pointers to uintptr_t, since standard libraries want integers
12014 * lisp.h (__executable_start): New decl.
12016 2012-05-31 Glenn Morris <rgm@gnu.org>
12018 * image.c (Fimagemagick_types): Doc fix.

12039 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
12041 Do not create empty overlays with the evaporate property (Bug#9642).
12042 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
12043 Bug#9642, but explicitly check that the buffer the overlay would
12044 be moved to is live and rearrange lines to make sure that errors
12045 will not put the overlay in an inconsistent state.
12046 (Fdelete_overlay): Cosmetics.
12048 2012-05-28 Eli Zaretskii <eliz@gnu.org>
12050 * w32term.c (my_bring_window_to_top): New function.
12051 (x_raise_frame): Use handle returned by DeferWindowPos, which
12052 could be different from the original one.

12062 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
12064 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
12065 This avoids undefined behavior that might cause the eassert
12066 to not catch an out-of-range value.
12068 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
12070 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):

12082 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
12084 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
12085 Only r_alloc_inhibit_buffer_relocation needed to be added;
12086 the others were already declared.
12088 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
12089 before checking whether it's out of range. Put the check inside
12091 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
12093 2012-05-27 Ken Brown <kbrown@cornell.edu>
12095 * callproc.c (Fcall_process): Restore a line that was accidentally
12096 commented out in the 2011-02-13 change (bug#11547).

12100 * lisp.h [REL_ALLOC]: Add prototypes for external functions
12101 defined on ralloc.c.
12103 * buffer.c [REL_ALLOC]: Remove prototypes of
12104 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
12105 they are now on lisp.h.
12107 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
12109 * search.c (search_buffer): Use it to inhibit relocation of buffer
12110 text while re_search_2 is doing its job, because re_search_2 is
12111 passed C pointers to buffer text. (Bug#11519)
12113 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
12114 Update value to 24.
12116 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
12117 state after an additional call to move_it_in_display_line_to, keep
12118 the values of it->max_ascent and it->max_descent found for the
12120 (pos_visible_p): Revert the comparison against bottom_y to what it
12121 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
12124 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
12126 Fix coding-related core dumps with gcc -ftrapv.
12127 The code was computing A - B, where A and B are pointers, and B is
12128 random garbage. This can lead to core dumps on platforms that
12129 have special pointer registers, and it also leads to core dumps on
12130 x86-64 when compiled with gcc -ftrapv. The fix is to compute
12131 A - B only when B is initialized properly.
12132 * coding.c (coding_set_source, coding_set_destination): Return void.
12133 (coding_change_source, coding_change_destinations): New functions,
12134 with the old behaviors of coding_set_source and coding_set_destination.
12135 All callers that need an offset changed to use these new functions.

12145 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
12147 * w32console.c: Include window.h.
12148 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
12150 (initialize_w32_display): Initialize mouse-highlight data.
12152 * w32inevt.c: Include termchar.h and window.h.
12153 (do_mouse_event): Support mouse-autoselect-window. When the mouse
12154 moves, call note_mouse_highlight. If help_echo changed, call
12155 gen_help_event to produce help-echo message in the echo area.
12156 Call clear_mouse_face if mouse_face_hidden is set in the mouse
12159 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
12161 * lread.c (read1): Simplify slightly to avoid an overflow warning
12162 with GCC 4.7.0 on x86-64.
12164 2012-05-26 Eli Zaretskii <eliz@gnu.org>
12166 * bidi.c (bidi_mirror_char): Revert last change: an int is
12167 definitely wide enough here.
12169 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
12171 Fix integer width and related bugs (Bug#9874).
12172 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
12173 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
12174 (string_bytes, check_sblock, allocate_string_data):
12175 (compact_small_strings, Fmake_bool_vector, make_string)
12176 (make_unibyte_string, make_multibyte_string)
12177 (make_string_from_bytes, make_specified_string)

12205 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12206 (validate_region): Omit unnecessary test for b <= e,
12207 since that's guaranteed by the previous test.
12208 (adjust_overlays_for_delete): Avoid pos + length overflow.
12209 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
12210 (report_overlay_modification):
12211 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12212 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
12213 Omit pointer cast, which isn't needed anyway, and doesn't work
12214 after the EMACS_INT -> ptrdiff_t change.
12215 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
12216 * buffer.h: Adjust decls to match defn changes elsewhere.

12221 not int, to avoid needless 32-bit limit on 64-bit hosts.
12222 (exec_byte_code): Use tighter memory-full test, one that checks
12223 for alloca overflow. Don't compute the address of the object just
12224 before an array, as that's not portable. Use EMACS_INT, not
12225 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
12226 * callint.c (Fcall_interactively):
12227 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
12228 * callproc.c (call_process_kill, Fcall_process):
12229 Don't assume pid_t fits into an Emacs fixnum.

12239 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12240 (casify_object): Avoid integer overflow when overallocating buffer.
12241 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
12242 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
12243 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
12244 * category.h (CATEGORYP): Don't assume arg is nonnegative.
12245 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the

12248 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12249 For CCL_MapSingle, check that content and value are in int range.
12250 (ccl_driver, Fregister_code_conversion_map):
12251 Check that Vcode_version_map_vector is a vector.
12252 (resolve_symbol_ccl_program): Check that vector header is in range.
12253 Always copy the vector, so that we can check its contents reliably
12254 now rather than having to recheck each instruction as it's being
12255 executed. Check that vector words fit in 'int'.
12256 (ccl_get_compiled_code, Fregister_ccl_program)
12257 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
12258 program indexes, to avoid needless 32-bit limit on 64-bit hosts.

12260 contents are in range.
12261 (Fccl_execute_on_string): Check that status is in range.
12262 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
12263 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
12264 Accept and return EMACS_INT, not int, because callers can pass values
12265 out of 'int' range.

12271 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
12272 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
12273 avoid mishandling large integers.

12282 Remove now-unnecessary CHECK_NATNUMs.
12283 (Fdefine_charset_internal): Check ranges here, more carefully.
12284 Don't rely on undefined behavior with signed left shift overflow.
12285 Don't assume unsigned int fits into fixnum, or that fixnum fits
12286 into unsigned int. Don't require max_code to be a valid fixnum;
12287 that's not true for gb10830 4-byte on a 32-bit host. Allow
12288 invalid_code to be a cons, for the same reason. Require code_offset
12289 to be a character. Avoid int overflow if max_char is close
12291 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
12292 this is intended anyway and avoids some undefined behavior.
12293 (load_charset_map): Pass unsigned, not int, as 2nd arg of
12294 INDEX_TO_CODE_POINT, as that's what it expects.
12295 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
12296 * charset.h (DECODE_CHAR): Return int, not unsigned;
12297 this is what was intended anyway, and it avoids undefined behavior.
12298 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
12299 integer-overflow issues.
12300 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
12301 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
12302 where the argument is EMACS_INT, and this behavior is not intended.
12303 * chartab.c (Fmake_char_table, Fset_char_table_range)
12304 (uniprop_get_decoder, uniprop_get_encoder):
12305 Don't assume fixnum fits in int.
12306 * cmds.c (move_point): New function, that does the gist of
12307 Fforward_char and Fbackward_char, but does so while checking
12308 for integer overflow more accurately.
12309 (Fforward_char, Fbackward_char): Use it.
12310 (Fforward_line, Fend_of_line, internal_self_insert)
12311 (internal_self_insert):
12312 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.

13081 (Fword_search_forward, Fword_search_backward_lax)
13082 (Fword_search_forward_lax): Move functions to isearch.el

13085 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
13087 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
13089 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
13091 * lread.c (init_obarray): Declare Qt and Qnil as special.
13093 2012-05-14 Glenn Morris <rgm@gnu.org>
13095 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
13096 Put "libexec" before "bin", for the sake of init_callproc_1.
13098 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
13100 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.

13103 (report_error, report_error_1, make_hdr, copy_sym)
13104 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
13105 Make arguments const char *, not char *, to avoid violations of C
13106 standard and to fix some AIX warnings reported by Gilles Pion.
13108 2012-05-14 Eli Zaretskii <eliz@gnu.org>
13110 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
13111 already have overlays loaded.
13112 (handle_single_display_spec): Before returning without displaying
13113 fringe bitmap, synchronize the bidi iterator with the main display
13114 iterator, by calling iterate_out_of_display_property.
13115 (iterate_out_of_display_property): Detect buffer iteration by
13116 testing that it->string is a Lisp string.
13117 (get_next_display_element): When the current object is exhausted,
13118 and there's something on it->stack, call set_iterator_to_next to
13119 proceed with what's on the stack, instead of returning zero.
13120 (set_iterator_to_next): If called at the end of a Lisp string,
13121 proceed to consider_string_end without incrementing string
13122 position. Don't increment display vector index past the end of
13123 the display vector. (Bug#11417)
13124 (pos_visible_p): Don't report a position visible when move_it_to
13125 stopped at the last line of window, which happens to be scanned
13126 backwards by the bidi iteration. (Bug#11464)
13128 2012-05-14 Eli Zaretskii <eliz@gnu.org>
13130 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
13131 and right-margin display specs even if the spec is invalid or we
13132 are on a TTY, and thus unable to display on the fringes.
13133 That's because the text with the property will not be displayed anyway,
13134 so we need to signal to the caller that this is a "replacing"
13135 display spec. This fixes display when the spec is invalid or we
13138 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
13140 * unexaix.c (make_hdr): Fix typo in prototype.
13141 This bug broke the build on AIX. Problem reported by Gilles Pion.
13143 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
13145 * keyboard.c (kbd_buffer_get_event): Read special events also in
13146 batch mode. (Bug#11415)
13148 2012-05-12 Glenn Morris <rgm@gnu.org>

13152 2012-05-12 Eli Zaretskii <eliz@gnu.org>
13154 * lisp.mk (lisp): Add newcomment.elc.
13156 2012-05-12 Glenn Morris <rgm@gnu.org>
13158 * Makefile.in (MKDIR_P): New, set by configure.
13159 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
13161 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
13163 Remove unused function hourglass_started.
13164 * dispextern.h (hourglass_started):
13165 * w32fns.c (hourglass_started):
13166 * xdisp.c (hourglass_started): Remove.

13170 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
13171 Update dependencies.
13173 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
13175 * xgselect.c (xg_select): Put maxfds+1 into a var.
13176 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
13178 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
13180 2012-05-10 Dave Abrahams <dave@boostpro.com>
13182 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
13183 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
13185 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
13187 * dbusbind.c (xd_registered_buses): New internal Lisp object.
13188 Rename all occurrences of Vdbus_registered_buses to xd_registered_buses.
13189 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
13190 Initialize xd_registered_buses.
13192 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
13194 Untag more efficiently if USE_LSB_TAG.
13195 This is based on a proposal by YAMAMOTO Mitsuharu in
13196 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
13197 For an admittedly artificial (nth 8000 longlist) benchmark on
13198 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
13199 Emacs's overall text size by 1%.
13200 * lisp.h (XUNTAG): New macro.
13201 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
13202 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
13203 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
13204 * eval.c (Fautoload):
13205 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
13206 * frame.h (XFRAME): Use XUNTAG.
13208 Port recent dbusbind.c changes to 32-bit --with-wide-int.
13209 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
13210 Remove unportable assumptions about print widths of types like
13212 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
13213 intptr_t when converting between pointer and integer, to avoid GCC
13214 warnings about wrong width.
13216 2012-05-09 Eli Zaretskii <eliz@gnu.org>
13218 * w32proc.c (new_child): Force Windows to reserve only 64KB of
13219 stack for each reader_thread, instead of defaulting to 8MB
13220 determined by the linker. This avoids failures in creating
13221 subprocesses on Windows 7, see the discussion in this thread:
13222 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
13224 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
13226 Fix up display of the *Minibuf-0* buffer in the mini window.
13227 * keyboard.c (read_char): Don't clear the echo area if there's no
13229 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
13230 contents of *Minibuf-0*) if there's no message displayed in its stead.
13232 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
13234 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
13237 2012-05-06 Chong Yidong <cyd@gnu.org>
13239 * lisp.mk (lisp): Update.
13241 2012-05-05 Jim Meyering <meyering@redhat.com>
13243 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
13245 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
13247 * data.c (PUT_ERROR): New macro.
13248 (syms_of_data): Use it. Add new error type `user-error'.
13249 * undo.c (user_error): New function.
13250 (Fprimitive_undo): Use it.
13251 * print.c (print_error_message): Adjust print style for `user-error'.
13252 * keyboard.c (user_error): New function.
13253 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
13255 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
13257 Do not limit current-time-string to years 1000..9999.
13258 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
13259 (Fcurrent_time_string): Support any year that is supported by the
13260 underlying localtime representation. Don't use asctime, as it
13261 has undefined behavior for years outside the range -999..9999.
13263 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
13265 Fix race conditions involving setenv, gmtime, localtime, asctime.
13266 Without this fix, interrupts could mess up code that uses these
13267 nonreentrant functions, since setting TZ invalidates existing
13268 tm_zone or tzname values, and since most of these functions return
13269 pointers to static storage.
13270 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
13271 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
13272 Grow the critical sections to include not just invoking
13273 localtime/gmtime, but also accessing these functions' results
13274 including their tm_zone values if any, and any related TZ setting.
13275 (format_time_string): Last arg is now struct tm *, not struct tm **,
13276 so that the struct tm is saved in the critical section.
13277 All callers changed. Simplify allocation of initial buffer, partly
13278 motivated by the fact that memory allocation needs to be outside
13279 the critical section.
13281 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
13283 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
13284 with RESET_INTERVAL.
13286 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
13287 Remove duplicated buffer name initialization.
13289 2012-05-02 Jim Meyering <jim@meyering.net>
13291 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
13293 * xfns.c (x_window): Use xstrdup (Bug#11375).
13295 2012-05-02 Eli Zaretskii <eliz@gnu.org>
13297 * xdisp.c (pos_visible_p): If already at a newline from the
13298 display string before the 'while' loop, don't walk back the glyphs
13299 from it3.glyph_row. Solves assertion violation when the display
13300 string begins with a newline (egg.el). (Bug#11367)
13302 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
13304 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
13307 2012-05-01 Glenn Morris <rgm@gnu.org>
13309 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
13310 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
13311 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
13312 All were removed before 23.1.
13314 * dispnew.c: Remove HAVE_LIBNCURSES test;
13315 it is always true on relevant platforms.
13317 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
13318 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
13320 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
13322 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
13324 * .gdbinit (xpr): Remove checks for no longer existing misc types.
13325 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
13328 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
13330 Do not avoid creating empty evaporating overlays (Bug#9642).
13331 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
13332 That is, do not delete an evaporating overlay if it becomes
13333 empty after its bounds are adjusted to fit within its buffer.
13334 This fix caused other problems, and I'm reverting it until we get
13335 to the bottom of them.
13337 2012-04-27 Chong Yidong <cyd@gnu.org>
13339 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
13341 2012-04-27 Eli Zaretskii <eliz@gnu.org>
13343 * xdisp.c (pos_visible_p): If the window start position is beyond
13344 ZV, start the display from buffer beginning. Prevents assertion
13345 violation in init_iterator when the minibuffer window is scrolled
13346 via the scroll bar.
13348 * window.c (window_scroll_pixel_based): Likewise.
13350 2012-04-27 Chong Yidong <cyd@gnu.org>
13352 * keymap.c (where_is_internal): Doc fix (Bug#10872).
13354 2012-04-27 Glenn Morris <rgm@gnu.org>
13356 * fileio.c (Fcopy_file, Fset_file_selinux_context):
13357 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
13359 2012-04-27 Eli Zaretskii <eliz@gnu.org>
13361 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
13362 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
13364 2012-04-26 Eli Zaretskii <eliz@gnu.org>
13366 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
13367 display element, check also the underlying string or buffer
13368 character. (Bug#11341)
13370 * w32menu.c: Include w32heap.h.
13371 (add_menu_item): If the call to AppendMenuW (via
13372 unicode_append_menu) fails, disable Unicode menus only if we are
13373 running on Windows 9X/Me.
13375 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
13377 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
13378 (xgetint): Add missing shift for LSB tags.
13380 2012-04-24 Martin Rudalics <rudalics@gmx.at>
13382 * keyboard.c (read_char): Don't wipe echo area for select window
13383 events: These might get delayed via `mouse-autoselect-window'
13386 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
13388 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
13389 manipulation of :loaded-from data.
13391 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
13393 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
13394 now a cons (bug#11311).
13396 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
13398 Do not create empty overlays with the evaporate property (Bug#9642).
13399 * buffer.c (Fmove_overlay): Delete an evaporating overlay
13400 if it becomes empty after its bounds are adjusted to fit within
13401 its buffer. Without this fix, in a nonempty buffer (let ((o
13402 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
13403 yields an empty overlay that has the evaporate property, which is
13404 not supposed to happen.
13406 Fix minor GTK3 problems found by static checking.
13407 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)

13426 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
13427 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
13428 (__malloc_size_t, __malloc_ptrdiff_t):
13429 Remove. All uses removed, replaced by the definiens if needed,
13430 since we can assume C89 or better now.
13431 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.

13439 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
13440 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
13441 Define using prototypes, not old style.

13506 * alloc.c: Handle unusual debugging option combinations.
13507 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
13508 since the two debugging options are incompatible.
13509 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS

13563 row, return zero immediately.
13564 (try_cursor_movement): If inside continuation line, don't back up
13565 farther than the first row after the header line, if any.

13606 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
13607 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined

13610 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
13611 Remove one incorrect comment and fix another.

13615 * ralloc.c (ALIGNED, ROUND_TO_PAGE, HEAP_PTR_SIZE)
13616 (r_alloc_size_in_use, r_alloc_freeze, r_alloc_thaw): Remove; unused.
13617 (r_alloc_sbrk): Now static.
13619 Improve ralloc.c interface checking.
13620 See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html
13621 * buffer.c (ralloc_reset_variable, r_alloc, r_re_alloc)

13648 * s/netbsd.h, s/sol2-6.h:
13649 Remove definition of GC_MARK_STACK, since the default now works.
13650 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
13651 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
13652 no longer the default.
13653 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
13655 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
13657 * lread.c (lisp_file_lexically_bound_p):

13667 * nsterm.m (constrainFrameRect): Always constrain when there is only
13668 one screen (Bug#10962).
13670 2012-04-13 Ken Brown <kbrown@cornell.edu>
13672 * s/cygwin.h (PTY_OPEN): Don't try to close a bogus file descriptor.
13674 2012-04-13 Reuben Thomas <rrt@sc3d.org>
13676 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
13678 2012-04-11 Daniel Colascione <dancol@dancol.org>
13680 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
13681 against is gone. It's better to use vfork now so that when Cygwin
13682 gains a new, working vfork, we use it automatically (bug#10398).
13684 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
13686 * window.c (save_window_save): Obey window-point-insertion-type.

13699 (force_quit_count): New var.
13700 (handle_interrupt): Use it.
13702 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
13704 * w32.c (w32_delayed_load): Record the full path of the library
13705 being loaded (bug#10424).
13707 2012-04-09 Glenn Morris <rgm@gnu.org>
13709 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
13710 not just in the obarray, before snarfing them. (Bug#11036)
13712 * Makefile.in ($(leimdir)/leim-list.el):
13713 Pass EMACS rather than BUILT_EMACS.
13715 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
13717 * process.c (make_process):
13718 * process.h: Add integer `gnutls_handshakes_tried' member to
13721 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
13722 Add convenience `GNUTLS_LOG2i' macro.
13724 * gnutls.c (gnutls_log_function2i): Convenience log function.
13725 (emacs_gnutls_read): Use new log functions,
13726 `gnutls_handshakes_tried' process member, and
13727 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
13728 attempts per process (connection).
13730 2012-04-09 Chong Yidong <cyd@gnu.org>
13732 * eval.c (Fuser_variable_p, user_variable_p_eh)
13733 (lisp_indirect_variable): Functions deleted.
13734 (Fdefvar): Caller changed.
13736 * callint.c (Finteractive, Fcall_interactively):
13737 * minibuf.c (Fread_variable): Callers changed.
13739 2012-04-09 Eli Zaretskii <eliz@gnu.org>
13741 * xdisp.c (set_cursor_from_row): If the display string appears in
13742 the buffer at position that is closer to point than the position
13743 after the display string, display the cursor on the first glyph of
13744 the display string. Fixes cursor display when a 'display' text
13745 property immediately follows invisible text. (Bug#11094)
13747 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
13749 composite.c: use 'double' consistently
13750 * composite.c (get_composition_id): Use 'double' consistently
13751 instead of converting 'float' to 'double' and vice versa; this is
13752 easier to understand and avoids a GCC warning.
13754 2012-04-09 Glenn Morris <rgm@gnu.org>
13756 * Makefile.in: Generate leim-list with bootstrap-emacs, in
13757 preparation for dumping it with emacs. (Bug#4789)
13758 (leimdir): New variable.
13759 ($(leimdir)/leim-list.el): New rule.
13760 (emacs$(EXEEXT)): Depend on leim-list.el.
13762 * buffer.c (Qucs_set_table_for_input): Remove. (Bug#9821)
13763 (Fget_buffer_create): Don't call Qucs_set_table_for_input.
13764 (init_buffer_once, syms_of_buffer): Remove Qucs_set_table_for_input.
13766 2012-04-08 Andreas Schwab <schwab@linux-m68k.org>

13774 Remove unused local variable.
13776 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
13778 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
13779 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
13780 (mark_memory): Mark Lisp_Objects only if pointers might hide in
13781 objects, as mark_maybe_pointer will catch them otherwise.
13782 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
13783 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
13785 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
13787 Fix typo that broke non-Windows builds.
13788 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.
13790 2012-04-07 Eli Zaretskii <eliz@gnu.org>
13792 Support building on MS-Windows with libxml2.
13794 * makefile.w32-in (OBJ2): Add xml.$(O).
13795 (GLOBAL_SOURCES): Add xml.c.
13796 ($(BLD)/xml.$(O)): New dependency list.
13798 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
13799 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
13800 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
13801 [!WINDOWSNT]: New macros.
13802 (init_libxml2_functions, libxml2_loaded_p): New functions.
13803 (parse_region): Call fn_xmlCheckVersion instead of using the macro
13804 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
13805 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
13806 Calls xmlCleanupParser only if libxml2 was loaded (or statically
13808 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
13809 Call init_libxml2_functions before calling libxml2 functions.
13810 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
13812 * emacs.c: Don't include libxml/parser.h.
13813 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
13814 xmlCleanupParser directly.
13816 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
13818 2012-04-07 Eli Zaretskii <eliz@gnu.org>
13820 * indent.c (Fvertical_motion): If there is a display string at
13821 point, use it.vpos to compute how many lines to backtrack after
13822 move_it_to point. (Bug#11133)
13824 2012-04-06 Eli Zaretskii <eliz@gnu.org>
13826 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
13827 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
13828 about subtle differences between FETCH_CHAR* and STRING_CHAR*
13829 macros related to unification of CJK characters. For the details,
13830 see the discussion following the message here:
13831 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
13833 2012-04-04 Chong Yidong <cyd@gnu.org>
13835 * keyboard.c (Vdelayed_warnings_list): Doc fix.
13837 2012-04-01 Eli Zaretskii <eliz@gnu.org>
13839 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
13840 instead of alloca. (Bug#11138)
13842 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
13844 * w32menu.c (is_simple_dialog): Properly check lisp types.
13847 2012-03-31 Eli Zaretskii <eliz@gnu.org>
13849 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
13850 position we get to after a call to move_it_to fails the
13851 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
13852 only if we wind up in a string from display property. (Bug#11063)
13854 * window.c (Fdelete_other_windows_internal): Invalidate the row
13855 and column information about mouse highlight, so that redisplay
13856 restores it after reallocating the glyph matrices. (Bug#7464)
13858 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
13859 string comes from a `display' text property, use the buffer
13860 position of that property as if we actually saw that position in
13862 (move_it_by_lines): Remove the assertion that
13863 "it->current_x == 0 && it->hpos == 0" which can be legitimately
13864 violated when there's a before-string at the beginning of a line.
13867 2012-03-30 Eli Zaretskii <eliz@gnu.org>
13869 * xdisp.c (append_space_for_newline): If the default face was
13870 remapped, use the remapped face for the appended newline.
13871 (extend_face_to_end_of_line): Use the remapped default face for
13872 extending the face to the end of the line.
13873 (display_line): Call extend_face_to_end_of_line when the default
13874 face was remapped. (Bug#11068)
13876 2012-03-29 Eli Zaretskii <eliz@gnu.org>
13878 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
13880 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
13882 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
13884 2012-03-27 Glenn Morris <rgm@gnu.org>
13886 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
13889 2012-03-26 Kenichi Handa <handa@m17n.org>
13891 * dispextern.h (struct glyph): Fix previous change. Change the
13892 bit length of glyphless.ch to 25 (Bug#11082).
13894 2012-03-26 Chong Yidong <cyd@gnu.org>
13896 * keyboard.c (Vselection_inhibit_update_commands): New variable.
13897 (command_loop_1): Use it; inhibit selection update for
13898 handle-select-window too (Bug#8996).
13900 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
13902 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
13904 2012-03-25 Kenichi Handa <handa@m17n.org>
13906 * dispextern.h (struct glyph): Change the bit length of
13907 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
13909 2012-03-24 Eli Zaretskii <eliz@gnu.org>
13911 * s/ms-w32.h (tzname): Include time.h before redirecting to
13912 _tzname. Fixes the MSVC build. (Bug#9960)
13914 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
13916 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
13919 * xterm.c (XTread_socket): Only modify handling_signal if
13920 !SYNC_INPUT. (Bug#11080)
13922 2012-03-23 Eli Zaretskii <eliz@gnu.org>
13924 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
13925 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
13926 when fetching a multibyte character consumes more bytes than
13927 CHAR_BYTES returns, due to unification of CJK characters in
13928 string_char. (Bug#11073)
13930 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
13932 * process.c (wait_reading_process_output): Handle pty disconnect
13933 by refraining from sending oneself a SIGCHLD (bug#10933).
13935 2012-03-22 Chong Yidong <cyd@gnu.org>
13937 * dispextern.h (struct it): New member string_from_prefix_prop_p.
13939 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
13940 Mark string as coming from a prefix property.
13941 (handle_face_prop): Use default face for prefix strings (Bug#4281).
13942 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
13944 2012-03-21 Chong Yidong <cyd@gnu.org>
13946 * xfaces.c (Vface_remapping_alist): Doc fix.
13948 2012-03-20 Eli Zaretskii <eliz@gnu.org>
13950 * w32proc.c (Fw32_set_console_codepage)
13951 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
13954 2012-03-20 Chong Yidong <cyd@gnu.org>
13956 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
13957 to reflect default non-nil value of redisplay-dont-pause.
13959 2012-03-19 Kenichi Handa <handa@m17n.org>
13961 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
13962 it fit in a valid range (Bug#11003).
13964 2012-03-18 Eli Zaretskii <eliz@gnu.org>
13966 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
13967 that is not from display property, accept the row as a "cursor
13968 row" if one of the string's character has a non-nil `cursor'
13969 property. Fixes cursor positioning when there are newlines in
13970 overlay strings, e.g. in icomplete.el. (Bug#11035)
13972 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
13974 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
13976 2012-03-12 Chong Yidong <cyd@gnu.org>
13978 * eval.c (inhibit_lisp_code): Rename from
13979 inhibit_window_configuration_change_hook; move from window.c.
13981 * xfns.c (unwind_create_frame_1, Fx_create_frame):
13982 * window.c (run_window_configuration_change_hook)
13983 (syms_of_window): Callers changed.
13985 2012-03-11 Chong Yidong <cyd@gnu.org>
13987 * keymap.c (Fkey_description): Doc fix (Bug#9700).
13989 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
13991 2012-03-10 Chong Yidong <cyd@gnu.org>
13993 * frame.c (other_visible_frames): Don't assume the selected frame
13994 is visible (Bug#10955).
13996 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
13998 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
14000 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
14002 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
14003 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
14006 2012-03-03 Glenn Morris <rgm@gnu.org>
14008 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
14010 2012-03-02 Eli Zaretskii <eliz@gnu.org>
14012 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
14013 position past the first glyph_row that ends at ZV. (Bug#10902)
14014 (redisplay_window, next_element_from_string): Fix typos in
14016 (redisplay_window): Pass to move_it_vertically the margin in
14017 pixels, not in screen lines.
14019 2012-03-02 Glenn Morris <rgm@gnu.org>
14021 * buffer.c (buffer-list-update-hook): Doc fix.
14023 2012-02-29 Eli Zaretskii <eliz@gnu.org>
14025 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
14026 push_it before setting up the iterator for the first overlay
14027 string, even if we have an empty string loaded.
14028 (next_overlay_string): If there's an empty string on the iterator
14029 stack, pop the stack. (Bug#10903)
14031 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
14033 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
14034 Suggested by Stefan Monnier in
14035 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
14036 * alloc.c (widen_to_Lisp_Object): New static function.
14037 (mark_memory): Also mark Lisp_Objects by fetching pointer words
14038 and widening them to Lisp_Objects. This would work even if
14039 USE_LSB_TAG is defined and wide integers are used, which might
14040 happen in a future version of Emacs.
14042 2012-02-25 Chong Yidong <cyd@gnu.org>
14044 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
14047 * xselect.c (Fx_selection_exists_p): Doc fix.
14048 (x_clipboard_manager_save_all): Print an informative message
14049 before saving to clipboard manager.
14051 2012-02-24 Chong Yidong <cyd@gnu.org>
14053 * keyboard.c (process_special_events): Handle all X selection
14054 requests in kbd_buffer, not just the next one (Bug#8869).
14056 2012-02-23 Chong Yidong <cyd@gnu.org>
14058 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
14059 call when setting menu-bar-lines and tool-bar-lines parameters.
14060 (unwind_create_frame_1): New helper function.
14062 * window.c (inhibit_window_configuration_change_hook): New var.
14063 (run_window_configuration_change_hook): Obey it.
14064 (syms_of_window): Initialize it.
14066 2012-02-22 Chong Yidong <cyd@gnu.org>
14068 * xterm.c (x_draw_image_relief): Add missing type check for
14069 Vtool_bar_button_margin (Bug#10743).
14071 2012-02-21 Chong Yidong <cyd@gnu.org>
14073 * fileio.c (Vfile_name_handler_alist): Doc fix.
14075 * buffer.c (Fget_file_buffer): Protect against invalid file
14076 handler return value.
14078 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
14080 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
14081 when computing $valmask.
14083 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
14084 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
14085 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
14086 It's useless in that case, and it can cause problems on hosts
14087 that allocate halves of EMACS_INT values separately.
14088 Reported by Dan Horák. Diagnosed by Andreas Schwab in
14089 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
14090 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
14091 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
14092 it avoids undefined behavior on hosts where shifting right by more
14093 than the word width has undefined behavior.
14095 2012-02-19 Chong Yidong <cyd@gnu.org>
14097 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
14098 (Funhandled_file_name_directory, Ffile_name_as_directory)
14099 (Fdirectory_file_name, Fexpand_file_name)
14100 (Fsubstitute_in_file_name): Protect against invalid file handler
14101 return values (Bug#10845).
14103 2012-02-18 Eli Zaretskii <eliz@gnu.org>
14105 * .gdbinit (pitx): Fix incorrect references to fields of the
14108 2012-02-17 Chong Yidong <cyd@gnu.org>
14110 * syntax.c (Fscan_lists): Doc fix (Bug#10833).
14112 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
14114 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
14115 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
14117 2012-02-15 Chong Yidong <cyd@gnu.org>
14119 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
14120 marked as special. Also, starting docstrings with * is obsolete.
14122 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
14124 * gnutls.c (emacs_gnutls_write): Fix last change.
14126 2012-02-13 Lars Ingebrigtsen <larsi@gnus.org>
14128 * gnutls.c (emacs_gnutls_write): Set errno appropriately for
14131 2012-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
14133 * keymap.c (Fsingle_key_description): Handle char ranges.
14135 2012-02-12 Chong Yidong <cyd@gnu.org>
14137 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
14138 as that creates a dangerous corner case.
14140 * window.c (Fdelete_window_internal): Invalidate the mouse
14141 highlight (Bug#9904).
14143 2012-02-12 Glenn Morris <rgm@gnu.org>
14145 * xselect.c (Fx_own_selection_internal)
14146 (Fx_get_selection_internal, Fx_disown_selection_internal)

14700 cases where the *-change-functions have already been properly called
14703 2011-12-01 Andreas Schwab <schwab@linux-m68k.org>
14705 * keyboard.c (interrupt_signal): Don't call kill-emacs when
14706 waiting for input. (Bug#10169)
14708 2011-11-30 Eli Zaretskii <eliz@gnu.org>
14710 * dispnew.c (adjust_glyph_matrix): Remove the assertion that
14711 verifies glyph row's hash code--we have just reallocated the
14712 glyphs, so their contents can be complete garbage. (Bug#10164)

14758 (ALIGN_GCTYPEBITS) [_MSC_VER]: Define.
14759 (DECL_ALIGN) [_MSC_VER]: Use it, as MSVC doesn't like bit ops in

14790 visible and out of scroll-margin. (Bug#10105)
14791 (start_display): Don't move to the next line if the display should
14792 start at a newline that is part of a display vector or an overlay

14872 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
14873 Otherwise, valgrind does not work on some platforms.
14874 Problem reported by Andreas Schwab in

14876 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
14877 is set, removing the need for VIRT_ADDRESS_VARIES.
14878 (PURE_P): Use a more-efficient implementation that needs just one
14879 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the

14885 consistency with the new puresize.h.
14886 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
14887 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

14893 (erase_phys_cursor, update_window_cursor, show_mouse_face)
14894 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
14895 behave as if the cursor position were at the window margin.
14897 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
14898 and the cursor position is out of bounds, behave as if the cursor
14899 position were at the window margin. (Bug#10075)
14901 2011-11-18 Chong Yidong <cyd@gnu.org>
14903 * window.c (Fwindow_combination_limit): Make first argument

14922 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
14924 * xdisp.c (row_hash): New function, body extracted from
14925 compute_line_metrics.
14926 (compute_line_metrics): Call row_hash, instead of computing the
14929 * dispnew.c (verify_row_hash): Call row_hash for computing the
14930 hash code of a row, instead of duplicating code from xdisp.c.
14932 * dispextern.h (row_hash): Add prototype.
14934 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
14936 * frame.c (delete_frame): Don't delete the terminal when the last

14962 (Fsplit_window_internal, saved_window)
14963 (Fset_window_configuration, save_window_save): Rename all

14972 * xdisp.c (display_line): Move the call to
14973 highlight_trailing_whitespace before the call to
14974 compute_line_metrics, since the latter needs to see the final
14975 faces of all the glyphs to compute ROW's hash value.

14985 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
14986 with user-defined heap size. Bump the default size of the temacs

14990 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
14991 current_matrix and desired_matrix. (Bug#9990)
14992 (verify_row_hash) [XASSERTS]: New function.
14993 (adjust_glyph_matrix, row_equal_p): Use it in xassert to verify

15037 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
15039 Avoid some portability problems by eschewing 'extern inline' functions.
15040 The trivial performance wins aren't worth the portability hassles; see
15041 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
15043 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
15044 (window_box_width, window_box_left, window_box_left_offset)

15092 This is also needed for porting to any host where GC_MARK_STACK is
15093 not GC_MAKE_GCPROS_NOOPS.
15094 (which_symbols): Use it.
15096 2011-11-07 Kenichi Handa <handa@m17n.org>
15098 * coding.c (coding_set_destination): Check coding->src_pos only
15099 when coding->src_object is a buffer (bug#9910).
15101 * process.c (send_process): Set the member src_multibyte of coding
15102 to 0 (bug#9911) when sending a unibyte text.

15105 process_coding to 0 (bug#9912).
15107 2011-11-06 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15109 * xmenu.c (cleanup_widget_value_tree): New function.
15110 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of
15111 calling free_menubar_widget_value_tree directly (Bug#9830).
15113 2011-11-06 Paul Eggert <eggert@cs.ucla.edu>
15115 Fix some portability problems with 'inline'.
15116 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
15117 (window_box_width, window_box_left, window_box_left_offset)
15118 (window_box_right, window_box_right_offset): Declare extern.
15119 Otherwise, these inline functions do not conform to C99 and
15120 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
15121 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
15122 * intervals.c (adjust_intervals_for_insertion)
15123 (adjust_intervals_for_deletion): Now extern, because otherwise the
15124 extern inline functions 'offset_intervals' couldn't refer to it.
15125 (static_offset_intervals): Remove.
15126 (offset_intervals): Rewrite using the old contents of
15127 static_offset_intervals. The old version didn't conform to C99
15128 because an extern inline function contained a reference to an
15129 identifier with static linkage.
15131 2011-11-06 Andreas Schwab <schwab@linux-m68k.org>
15133 * keyboard.c (interrupt_signal): Don't call kill-emacs while in

15139 iterator's bidi_p flag if Vpurify_flag is non-nil. (Bug#9963)
15140 (Fcurrent_bidi_paragraph_direction): If Vpurify_flag is non-nil,
15141 return Qleft_to_right.

15150 (Fwindow_margins, Fwindow_fringes, Fwindow_scroll_bars)
15151 (Fwindow_vscroll): Doc fix.
15152 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
15153 argument, since it makes no sense to pass a live window and for
15154 consistency with window-child.

15182 (unwind_create_frame): New function (Bug#9943).
15183 (Fx_create_frame): Restructure code to be more similar to the one in
15184 xfns.c. Call record_unwind_protect with unwind_create_frame (Bug#9943).
15185 Initialize image_cache_refcount if GLYPH_DEBUG (Bug#9943).
15186 Move terminal->reference_count++ just before making the frame official
15189 * nsterm.m (x_free_frame_resources): New function.

15194 Move terminal->reference_count++ just before making the frame
15195 official. Move initialization of image_cache_refcount and
15196 dpyinfo_refcount before calling init_frame_faces (Bug#9943).

15236 previous/next-single-property-change returns nil, treat that as
15237 the beginning or the end of the buffer. (Bug#9955)
15239 2011-11-04 Jan Djärv <jan.h.d@swipnet.se>
15241 * gtkutil.c (xg_make_tool_item): Add callbacks if one of wimage or

15264 (mouse_face_from_buffer_pos, note_mouse_highlight):
15265 Rename cover_string to disp_string.
15267 2011-11-01 Martin Rudalics <rudalics@gmx.at>

15270 Vtemp_buffer_show_specifiers.
15271 (Vtemp_buffer_show_specifiers): Remove unused variable.
15273 2011-10-30 Eli Zaretskii <eliz@gnu.org>
15275 * xdisp.c (try_cursor_movement): Make sure ROW isn't decremented
15276 past the beginning of the current glyph matrix.
15278 2011-10-30 Adam Sjøgren <asjo@koldfront.dk> (tiny change)
15280 * xterm.c: Include X11/Xproto.h if HAVE_GTK3.
15281 (x_error_handler): Ignore BadMatch for X_SetInputFocus for

15324 2011-10-29 Glenn Morris <rgm@gnu.org>
15326 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
15327 Not clear what it was for, and it causes various bugs. (Bug#9839)
15329 2011-10-28 Eli Zaretskii <eliz@gnu.org>
15331 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a

15351 2011-10-28 Eli Zaretskii <eliz@gnu.org>
15353 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem

15364 (w32font_open_internal, compute_metrics):
15365 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
15366 instead of calling the "wide" APIs directly.
15368 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
15370 * w32.h (syms_of_w32font): Add prototype.
15372 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
15374 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)

15376 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
15377 (Fmove_to_window_line): Doc fix.
15379 2011-10-27 Chong Yidong <cyd@gnu.org>
15381 * process.c (make_process): Set gnutls_state to NULL.
15383 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
15384 non-NULL, regardless of GNUTLS_INITSTAGE.
15385 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal

15412 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
15414 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).

15433 (bidi_resolve_weak): Don't enter the expensive loop if the current
15434 position is before next_en_pos. Record the bidi type of the first
15435 non-ET, non-BN character we find, in addition to its position.
15436 (bidi_level_of_next_char): Invalidate next_en_type when
15437 next_en_pos is over-stepped.
15439 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
15441 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
15442 * editfns.c: Rewrite current-time-zone so that it invokes
15443 the equivalent of (format-time-string "%Z") to get the time zone name.
15444 This fixes a bug when the time zone name contains characters that
15445 need converting from the system time locale to Emacs internal format.
15446 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
15447 that patch fixed format-time-string to do the conversion, but
15448 I forgot to fix current-time-zone.
15449 (format_time_string): New function, containing most of
15450 what Fformat_time_string used to contain.
15451 (Fformat_time_string): Rewrite in terms of format_time_string.
15452 This doesn't change this function's behavior.
15453 (current-time-zone): Rewrite to use format_time_string.
15454 This fixes the bug reported by Michael Schierl in
15455 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
15456 Jason Rumney's 2007-06-07 change worked around this bug, but
15458 * systime.h (tzname, timezone): Remove no-longer-used declarations.
15460 2011-10-19 Eli Zaretskii <eliz@gnu.org>
15462 * xdisp.c (start_display): If the character at POS is displayed
15463 via a display vector, reset IT->current.dpvec_index to zero.
15464 (try_window_reusing_current_matrix): If a line ends in a display
15465 vector or the next line starts in a display vector, continue
15466 redrawing the window even though the character position of
15467 start_row was reached.
15470 2011-10-18 Chong Yidong <cyd@gnu.org>
15472 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
15473 with nobreak-char-display too.
15475 2011-10-18 Eli Zaretskii <eliz@gnu.org>
15477 Fix part 3 of bug#9771.
15478 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
15479 (bidi_resolve_neutral): Don't enter the expensive loop looking for
15480 non-neutral characters if the current character is a paragraph
15481 separator (a.k.a. Newline). This avoids running the same
15482 expensive loop twice, once when we consume the preceding newline
15483 and the other time when the line actually needs to be displayed.
15484 Avoid the loop when we see neutrals on the base embedding level
15485 following a character whose directionality is the same as the
15486 paragraph's. This avoids running the expensive loop when a line
15487 ends in a long sequence of neutrals, like control characters.
15488 Add assertion against STRONG_AL type. Slightly rearrange code
15489 that determines the type of a neutral given the first non-neutral
15491 (bidi_level_of_next_char): Set next_en_pos to zero when
15492 invalidating its info.
15494 2011-10-17 Eli Zaretskii <eliz@gnu.org>
15496 * xdisp.c (push_display_prop): Determine whether to record string
15497 or buffer position by IT->string, not by IT->method. Allow
15498 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
15499 (move_it_vertically_backward): Don't look for character position
15500 immediately after the newline when in a continuation line.
15503 2011-10-15 Martin Rudalics <rudalics@gmx.at>
15505 * window.c (coordinates_in_window): Rewrite and delabelize
15506 vertical border check. (Bug#5357) (Bug#9618)
15508 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
15510 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
15511 errors in XSetWindowBorder (bug#9310).
15513 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
15515 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
15516 avoid crash when xmalloc overrun checking is enabled.
15518 2011-10-13 Eli Zaretskii <eliz@gnu.org>
15520 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
15521 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
15522 cursor motion with <left> and <right> arrow keys.
15524 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
15525 some callers set that themselves.
15527 2011-10-12 Eli Zaretskii <eliz@gnu.org>
15529 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
15530 display string and the previous row comes from the same string and
15531 is empty. (Bug#9739) (Bug#9738)
15533 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
15535 * doc.c (get_doc_string): Encode file name (bug#9735).
15537 2011-10-12 Eli Zaretskii <eliz@gnu.org>
15539 * bidi.c (bidi_level_of_next_char):
15540 * xdisp.c (get_visually_first_element): Remove old incorrect
15541 comments regarding the Unicode Line Separator character.
15543 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
15545 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
15547 * alloc.c (Fgc_status): Do not access beyond zombies array
15548 boundary if nzombies > MAX_ZOMBIES.
15549 * alloc.c (dump_zombies): Add missing format specifier.
15551 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
15553 * xdisp.c (set_cursor_from_row): Simplify conditionals,
15554 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
15556 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
15557 Some packages use them to denote characters with modifiers.
15559 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
15561 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
15562 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
15563 matching a pp-number. Rename parameter var to var1.
15565 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
15567 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
15569 2011-10-08 Glenn Morris <rgm@gnu.org>
15571 * callint.c (Fcall_interactively): Give a more explicit error for the
15572 'c' case with a non-character input. (Bug#8479)
15574 2011-10-08 Eli Zaretskii <eliz@gnu.org>
15576 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
15578 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
15579 lines that are hscrolled on the left.
15581 * dispnew.c (buffer_posn_from_coords): Account for a possible
15582 presence of header-line. (Bug#4426)
15584 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
15586 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
15587 Don't advertise functionality which we discourage or doesn't work.
15589 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
15591 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
15592 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
15593 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
15594 this makes Emacs dump core during garbage collection on rare
15595 occasions. sizeof is obviously inferior to offsetof here, so
15596 stick with offsetof.
15597 (GC_POINTER_ALIGNMENT): New macro.
15598 (mark_memory): Omit 3rd (offset) arg; caller changed.
15599 Don't assume EMACS_INT alignment is the same as pointer alignment.
15601 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
15603 * keyboard.c (read_key_sequence_remapped): New var.
15604 (read_key_sequence): Compute remapping in the right buffer.
15605 (command_loop_1): Use read_key_sequence's remapping directly.
15607 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
15609 * dired.c (file_name_completion): Don't expand file name.
15610 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
15611 before checking file name handler.
15613 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
15614 they've been requested explicitly (bug#9591).
15616 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
15618 * keymap.c (Fsingle_key_description): Use make_specified_string
15619 instead of build_string to build string from push_key_description.
15622 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
15624 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
15625 This fixes a Y2038 bug on 64-bit hosts.
15626 * buffer.c (reset_buffer):
15627 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
15628 (Fclear_buffer_auto_save_failure):
15629 Use 0, not -1, to represent an unset failure time, since time_t
15630 might not be signed.
15632 Remove dependency on glibc malloc internals.
15633 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15634 Move back here from lisp.h, but with their new implementations.
15635 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15636 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
15637 * charset.c (charset_table_init): New static var.
15638 (syms_of_charset): Use it instead of xmalloc. This removes a
15639 dependency on glibc malloc internals. See Eli Zaretskii's comment in
15640 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
15641 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15642 Move back to alloc.c.
15643 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15644 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
15646 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
15648 * nsterm.m (windowDidResize): Call x_set_window_size only when
15649 ns_in_resize is true. Otherwise set pixelwidth/height and
15650 call change_frame_size (Bug#9628).
15652 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
15654 Port --enable-checking=all to Fedora 14 x86-64.
15655 * charset.c (syms_of_charset): Also account for glibc malloc's
15656 internal overhead when calculating the initial malloc maximum.
15658 Port --enable-checking=all to Fedora 14 x86.
15659 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15661 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
15662 (overrun_check_realloc, overrun_check_free):
15663 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
15664 That way, xmalloc returns a properly-aligned pointer even if
15665 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
15666 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
15667 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
15668 into account when calculating the initial malloc maximum.
15669 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
15670 Move here from alloc.c, so that charset.c can use it too.
15671 Properly align; the old code wasn't right for common 32-bit hosts
15672 when configured with --enable-checking=all.
15673 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
15674 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
15676 2011-09-29 Eli Zaretskii <eliz@gnu.org>
15678 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
15681 2011-09-28 Eli Zaretskii <eliz@gnu.org>
15683 * xdisp.c (compute_display_string_end): If there's no display
15684 string at CHARPOS, return -1.
15686 * bidi.c (bidi_fetch_char): When compute_display_string_end
15687 returns a negative value, treat the character as a normal
15688 character not covered by a display string. (Bug#9624)
15690 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
15692 * lread.c (Fread_from_string): Fix typo in docstring.
15694 2011-09-27 Eli Zaretskii <eliz@gnu.org>
15696 * xdisp.c (handle_invisible_prop): If invisible text ends on a
15697 newline, reseat the iterator instead of bidi-iterating there one
15698 character at a time. (Bug#9610)
15699 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
15700 TO_CHARPOS if the bidi iterator is at base embedding level.
15702 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
15704 * lread.c (readevalloop): Use correct code for NBSP.
15705 (read1): Likewise. (Bug#9608)
15707 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
15709 * dbusbind.c (Fdbus_register_signal): When service is not
15710 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
15712 2011-09-25 Glenn Morris <rgm@gnu.org>
15714 * buffer.c (truncate-lines): Doc fix.
15716 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
15718 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
15719 (Fset_window_next_buffers): Doc fix.
15721 2011-09-24 Glenn Morris <rgm@gnu.org>
15723 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
15725 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
15727 Fix minor problems found by static checking.
15728 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
15729 * indent.c (Fvertical_motion): Fix == vs = typo.
15731 2011-09-24 Eli Zaretskii <eliz@gnu.org>
15733 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
15734 Default value is now t. Doc fix.
15736 * indent.c (Fvertical_motion): Compute and apply the overshoot
15737 logic when moving up, not only when moving down. Fix the
15738 confusing name and values of the it_overshoot_expected variable;
15739 logic changes accordingly. (Bug#9254) (Bug#9549)
15741 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
15742 CHARPOS is covered by a display string which includes newlines.
15743 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
15744 is covered by a display string with embedded newlines.
15746 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
15748 * dbusbind.c (Fdbus_register_signal): Add match rule to
15749 Vdbus_registered_objects_table. (Bug#9581)
15750 (Fdbus_register_method, Vdbus_registered_objects_table):
15753 2011-09-24 Jim Meyering <meyering@redhat.com>
15755 do not ignore write error for any output size
15756 The previous change was incomplete.
15757 While it makes emacs --batch detect the vast majority of stdout
15758 write failures, errors were still ignored whenever the output size is
15759 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
15760 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
15761 && echo FAIL: ignored write error
15762 FAIL: ignored write error
15763 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
15764 && echo FAIL: ignored write error
15765 FAIL: ignored write error
15766 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
15768 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
15770 * emacs.c (Fkill_emacs): In noninteractive mode exit
15771 non-successfully if a write error occurred on stdout. (Bug#9574)
15773 2011-09-21 Eli Zaretskii <eliz@gnu.org>
15775 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
15778 * dispextern.h (struct it): Update the comment documenting what
15781 2011-09-20 Eli Zaretskii <eliz@gnu.org>
15783 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
15784 a display string, extend search for cursor position to end of row.
15785 (find_row_edges): If the row ends in a newline from a display
15786 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
15787 Handle the case of a display string with multiple newlines.
15788 (Fcurrent_bidi_paragraph_direction): Fix search for previous
15789 non-empty line. Fixes confusing cursor motion with arrow keys at
15790 the beginning of a line that starts with whitespace.
15792 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
15794 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
15797 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
15799 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
15800 boolean (Bug#9154).
15802 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15804 * xdisp.c (display_line): Record maximum and minimum buffer
15805 positions even if no glyphs were produced (e.g., by a zero-width
15806 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
15807 buffer positions that will be removed from the glyph row because
15809 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
15810 column is beyond frame width: don't subtract 1 "pixel" when
15811 computing width of the stretch.
15812 (reseat_at_next_visible_line_start): Undo the change made on
15813 2011-09-17 that saved paragraph information and restored it after
15814 the call to `reseat'. (Bug#9545)
15816 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
15818 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
15819 and turn window cursor on if cleared (Bug#9415).
15821 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
15823 * search.c (boyer_moore): Take unibyte characters from pattern
15824 literally. (Bug#9458)
15826 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15828 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
15830 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
15832 Fix minor problem found by static checking.
15833 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
15834 initialized, to pacify gcc -Wuninitialized.
15836 * fileio.c: Report proper errno when syscall falls.
15837 (Finsert_file_contents): Save and restore errno,
15838 so that report_file_error outputs the correct diagnostic.
15839 (Fwrite_region) [CLASH_DETECTION]: Likewise.
15841 2011-09-18 Eli Zaretskii <eliz@gnu.org>
15843 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
15845 2011-09-17 Eli Zaretskii <eliz@gnu.org>
15847 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
15848 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
15850 2011-09-17 Eli Zaretskii <eliz@gnu.org>
15852 * xdisp.c (reseat_at_next_visible_line_start): Keep information
15853 about the current paragraph and restore it after the call to reseat.
15855 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
15856 (bidi_find_paragraph_start): Search back for paragraph beginning
15857 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
15858 (bidi_move_to_visually_next): Only trigger paragraph-related
15859 computations when the last character is a newline or at EOB, not
15860 just any NEUTRAL_B. (Bug#9470)
15862 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
15863 truncated lines if point is covered by a display string. (Bug#9524)
15865 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
15867 * xselect.c: Relax test for outgoing X longs (Bug#9498).
15868 (cons_to_x_long): New function.
15869 (lisp_data_to_selection_data): Use it. Correct the test for
15870 short-versus-long data; it was negated. Break out of vector
15871 loop, for efficiency, when a long datum is discovered.
15873 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
15875 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
15877 2011-09-16 Eli Zaretskii <eliz@gnu.org>
15879 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
15880 GCC PR/17406) by declaring this function with external scope.
15882 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
15884 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
15885 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
15887 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
15889 * editfns.c (Fformat): Correctly handle text properties on "%%".
15891 2011-09-15 Eli Zaretskii <eliz@gnu.org>
15893 * xterm.c (x_draw_composite_glyph_string_foreground):
15894 * w32term.c (x_draw_composite_glyph_string_foreground):
15895 * term.c (encode_terminal_code):
15896 * composite.c (composition_update_it, get_composition_id):
15897 * xdisp.c (get_next_display_element)
15898 (fill_composite_glyph_string): Add comments about special meaning
15899 of TAB characters in a composition.
15901 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
15903 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
15904 This occurs when processing a multibyte format.
15905 Problem reported by Wolfgang Jenker.
15907 2011-09-15 Johan Bockgård <bojohan@gnu.org>
15909 * xdisp.c (try_cursor_movement): Only check for exact match if
15910 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
15912 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
15914 Remove unused external symbols.
15915 * dispextern.h (calc_pixel_width_or_height): Remove decl.
15916 * xdisp.c (calc_pixel_width_or_height): Now static.
15917 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
15918 * indent.c (check_display_width):
15919 * w32term.c: Fix comment to match code.
15920 * xterm.c, xterm.h (x_catching_errors): Remove.
15922 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
15924 * xselect.c: Use signed conversions more consistently (Bug#9498).
15925 (selection_data_to_lisp_data): Assume incoming selection data are
15926 signed integers, not unsigned. This is to be consistent with
15927 outgoing selection data, which was modified to use signed integers
15928 in as part of the fix to Bug#9196 in response to Jan D.'s comment
15929 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
15930 expects long, not unsigned long.
15932 2011-09-14 Eli Zaretskii <eliz@gnu.org>
15934 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
15935 computation of loop end. Reported by Johan Bockgård
15938 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
15940 * frame.c (Fother_visible_frames_p): Function deleted.
15942 2011-09-12 Eli Zaretskii <eliz@gnu.org>
15944 * indent.c (compute_motion): Process display vector front to back
15945 rather than the other way around. (Bug#2496)
15947 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
15949 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
15951 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
15953 * minibuf.c (Fread_from_minibuffer): Doc fix.
15955 2011-09-11 Eli Zaretskii <eliz@gnu.org>
15957 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
15958 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
15960 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
15962 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
15963 value for non-existent files.
15965 2011-09-11 Eli Zaretskii <eliz@gnu.org>
15967 * fileio.c (Finsert_file_contents): If the file cannot be opened,
15968 set its "size" to -1. This will set the modtime_size field of
15969 the corresponding buffer to -1, which is what
15970 verify-visited-file-modtime expects for files that do not exist.
15973 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
15975 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
15977 * lisp.h: ... from here. push_key_description is no longer
15978 defined in keyboard.c, so its declaration should not be in
15979 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
15980 logically belongs with push_key_description.
15982 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
15984 * buffer.h: Include <sys/types.h> instead of <time.h>.
15985 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
15986 Problem reported by Herbert J. Skuhra.
15988 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
15990 * xml.c (parse_region): Make the parsing work for
15991 non-comment-starting XML files again (bug#9144).
15993 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
15995 * image.c (gif_load): Fix calculation of bottom and right corner.
15998 2011-09-10 Eli Zaretskii <eliz@gnu.org>
16000 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
16001 redisplay in small windows.
16003 2011-09-09 Eli Zaretskii <eliz@gnu.org>
16005 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
16007 2011-09-08 Martin Rudalics <rudalics@gmx.at>
16009 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
16010 Operate on live windows only.
16012 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
16014 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
16016 2011-09-07 Eli Zaretskii <eliz@gnu.org>
16018 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
16019 only under bidi iteration.
16021 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
16023 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
16025 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
16027 isnan: Fix porting problem to Solaris 10 with bundled gcc.
16028 Without this fix, the command to link temacs failed due to an
16029 undefined symbol __builtin_isnan. This is because
16030 /usr/include/iso/math_c99.h #defines isnan(x) to
16031 __builtin_isnan(x), but the bundled gcc, which identifies itself
16032 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
16034 * floatfns.c (isnan): #undef, and then #define to a clone of
16036 (Fisnan): Always define, since it's always available now.
16037 (syms_of_floatfns): Always define isnan at the Lisp level.
16039 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
16041 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
16043 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
16045 * fileio.c: Fix bugs with large file offsets (Bug#9428).
16046 The previous code assumed that file offsets (off_t values) fit in
16047 EMACS_INT variables, which is not true on typical 32-bit hosts.
16048 The code messed up by falsely reporting buffer overflow in cases
16049 such as (insert-file-contents "big" nil 1 2) into an empty buffer
16050 when "big" contains more than 2**29 bytes, even though this
16051 inserts just one byte and does not overflow the buffer.
16052 (Finsert_file_contents): Store file offsets as off_t
16053 values, not as EMACS_INT values. Check for overflow when
16054 converting between EMACS_INT and off_t. When checking for
16055 buffer overflow or for overlap, take the offsets into account.
16056 Don't use EMACS_INT for small values where int suffices.
16057 When checking for overlap, fix a typo: ZV was used where
16058 ZV_BYTE was intended.
16059 (Fwrite_region): Don't assume off_t fits into 'long'.
16060 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
16062 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
16064 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
16066 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
16068 sprintf-related integer and memory overflow issues (Bug#9412).
16070 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
16071 (esprintf, exprintf, evxprintf): New functions.
16072 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
16073 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
16074 (modify_event_symbol): Do not assume that the length of
16075 name_alist_or_stem is safe to alloca and fits in int.
16076 (Fexecute_extended_command): Likewise for function name and binding.
16077 (Frecursion_depth): Wrap around reliably on integer overflow.
16078 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
16079 since some callers pass EMACS_INT values.
16080 (Fsingle_key_description): Don't crash if symbol name contains more
16081 than MAX_ALLOCA bytes.
16082 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
16083 (get_minibuffer): Arg is now EMACS_INT, not int.
16084 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
16085 (esprintf, exprintf, evxprintf): New decls.
16086 * window.h (command_loop_level, minibuf_level): Reflect API changes.
16088 * dbusbind.c (signature_cat): New function.
16089 (xd_signature, Fdbus_register_signal):
16090 Do not overrun buffer; instead, report string overflow.
16092 * dispnew.c (add_window_display_history): Don't overrun buffer.
16093 Truncate instead; this is OK since it's just a log.
16095 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
16096 even if the time zone offset is outlandishly large.
16097 Don't mishandle offset == INT_MIN.
16099 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
16100 when creating daemon; the previous buffer-overflow check was incorrect.
16102 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
16103 which has the guts of the old verror function.
16105 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
16106 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
16108 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
16109 (font_unparse_xlfd): Don't blindly alloca long strings.
16110 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
16111 fits in int, when using sprintf. Use single snprintf to count
16112 length of string rather than counting it via multiple sprintfs;
16113 that's simpler and more reliable.
16114 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
16115 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
16116 sprintf, in case result does not fit in int.
16118 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
16119 (fontset_from_font): Print it.
16121 * frame.c (tty_frame_count): Now printmax_t, not int.
16122 (make_terminal_frame, set_term_frame_name): Print it.
16123 (x_report_frame_params): In X, window IDs are unsigned long,
16124 not signed long, so print them as unsigned.
16125 (validate_x_resource_name): Check for implausibly long names,
16126 and don't assume name length fits in 'int'.
16127 (x_get_resource_string): Don't blindly alloca invocation name;
16128 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
16131 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
16132 (xg_check_special_colors, xg_set_geometry):
16133 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
16135 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
16136 Use esprintf, not sprintf, in case result does not fit in int.
16138 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
16139 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
16140 it as a large positive number.
16141 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
16142 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
16144 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
16145 in case result does not fit in int.
16147 * print.c (float_to_string): Detect width overflow more reliably.
16148 (print_object): Make sprintf buffer a bit bigger, to avoid potential
16149 buffer overrun. Don't assume list length fits in 'int'. Treat
16150 print length of 0 as 0, not as infinity; to be consistent with other
16151 uses of print length in this function. Don't overflow print length
16152 index. Don't assume hash table size fits in 'long', or that
16153 vectorlike size fits in 'unsigned long'.
16155 * process.c (make_process): Use printmax_t, not int, to format
16156 process-name gensyms.
16158 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
16160 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
16161 to avoid potential buffer overrun.
16163 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
16164 if X resource line is longer than 512 bytes.
16166 * xfns.c (x_window): Make sprintf buffer a bit bigger
16167 to avoid potential buffer overrun.
16169 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
16171 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
16173 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
16175 Integer overflow fixes for scrolling, etc.
16176 Without these, Emacs silently mishandles large integers sometimes.
16177 For example, "C-u 4294967297 M-x recenter" was treated as if
16178 it were "C-u 1 M-x recenter" on a typical 64-bit host.
16180 * xdisp.c (try_window_id): Check Emacs fixnum range before
16181 converting to 'int'.
16183 * window.c (window_scroll_line_based, Frecenter):
16184 Check that an Emacs fixnum is in range before assigning it to 'int'.
16185 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
16186 values converted from Emacs fixnums.
16187 (Frecenter): Don't wrap around a line count if it is out of 'int'
16188 range; instead, treat it as an extreme value.
16189 (Fset_window_configuration, compare_window_configurations):
16190 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
16192 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
16193 that can exceed INT_MAX. Check that EMACS_INT value is in range
16194 before assigning it to the (possibly-narrower) index.
16195 (match_limit): Don't assume that a fixnum can fit in 'int'.
16197 * print.c (print_object): Use ptrdiff_t, not int, for index that can
16200 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
16201 (Fvertical_motion): Don't wrap around LINES values that don't fit
16202 in 'int'. Instead, treat them as extreme values. This is good
16203 enough for windows, which can't have more than INT_MAX lines anyway.
16205 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
16207 * Require libxml/parser.h to avoid compilation warning.
16209 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
16211 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
16212 since this reportedly can destroy thread storage.
16214 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
16216 * syntax.c (find_defun_start): Update all cache variables if
16217 exiting early (Bug#9401).
16219 2011-08-30 Eli Zaretskii <eliz@gnu.org>
16221 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
16223 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
16224 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
16225 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
16227 * term.c (tty_append_glyph): New function.
16228 (produce_stretch_glyph): Static function and its prototype deleted.
16230 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
16233 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
16235 * image.c (parse_image_spec): Check for nonnegative, not for positive,
16236 when checking :margin (Bug#9390).
16237 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
16238 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
16239 so that the name doesn't mislead. All uses changed.
16241 2011-08-28 Johan Bockgård <bojohan@gnu.org>
16243 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
16246 2011-08-27 Eli Zaretskii <eliz@gnu.org>
16248 * xdisp.c (move_it_to): Don't bail out early when reaching
16249 position beyond to_charpos, if we are scanning backwards.
16250 (move_it_vertically_backward): When DY == 0, make sure we get to
16251 the first character in the line after the newline.
16253 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
16255 * ccl.c: Improve and simplify overflow checking (Bug#9196).
16256 (ccl_driver): Do not generate an out-of-range pointer.
16257 (Fccl_execute_on_string): Remove unnecessary check for
16258 integer overflow, noted by Stefan Monnier in
16259 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
16260 Remove a FIXME that didn't need fixing.
16261 Simplify the newly-introduced buffer reallocation code.
16263 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
16265 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
16267 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
16269 Integer and memory overflow issues (Bug#9196).
16271 * doc.c (get_doc_string): Rework so that
16272 get_doc_string_buffer_size is the actual buffer size, rather than
16273 being 1 less than the actual buffer size; this makes xpalloc more
16276 * image.c (x_allocate_bitmap_record, cache_image):
16277 * xselect.c (Fx_register_dnd_atom):
16278 Simplify previous changes by using xpalloc.
16280 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
16281 since either will do and ptrdiff_t is convenient with xpalloc.
16283 * charset.c (charset_table_size)
16284 (struct charset_sort_data.priority): Now ptrdiff_t.
16285 (charset_compare): Don't overflow if priorities differ greatly.
16286 (Fsort_charsets): Don't assume list length fits in int.
16287 Check for size-calculation overflow when allocating sort data.
16288 (syms_of_charset): Allocate an initial charset table that is
16289 just under 64 KiB, to avoid problems with glibc malloc and mmap.
16291 * cmds.c (internal_self_insert): Check for size-calculation overflow.
16293 * composite.h (struct composition.glyph_len): Now int, not unsigned.
16294 The actual value is always <= INT_MAX, and leaving it unsigned made
16295 overflow checking harder.
16297 * dispextern.h (struct glyph_matrix.rows_allocated)
16298 (struct face_cache.size): Now ptrdiff_t, for convenience in use
16299 with xpalloc. The values are still always <= INT_MAX.
16301 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
16303 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
16304 (SAFE_NALLOCA): New macro.
16306 * region-cache.c (struct boundary.pos, find_cache_boundary)
16307 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
16308 (set_cache_region, invalidate_region_cache)
16309 (revalidate_region_cache, know_region_cache, region_cache_forward)
16310 (region_cache_backward, pp_cache):
16311 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
16312 so that ptrdiff_t * can be passed to xpalloc.
16313 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
16314 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
16315 (pp_cache): Don't assume cache_len fits in int.
16316 * region-cache.h: Adjust extern decls to match.
16318 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
16319 EMACS_INT, since either will do, for xpalloc.
16321 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
16322 (xnmalloc, xnrealloc, xpalloc): New functions.
16324 * bidi.c (bidi_shelve_header_size): New constant.
16325 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
16326 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
16328 * bidi.c (bidi_cache_shrink):
16329 * buffer.c (overlays_at, overlays_in, record_overlay_string)
16331 Don't update size of array until after memory allocation succeeds,
16332 because xmalloc/xrealloc may not return.
16333 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
16334 now that we have proper integer overflow checking.
16335 (record_overlay_string, overlay_strings): Catch overflows when
16336 calculating size of overlay_str_buf.
16338 * callproc.c (Fcall_process): Check for size overflow when
16339 calculating size of args2.
16340 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
16341 Normally we prefer signed values, but sticking with ptrdiff_t would
16342 require adding more-complicated checks.
16344 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
16345 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
16346 Redo buffer-overflow calculations to avoid integer overflow.
16347 Add a FIXME comment where memory seems to be over-allocated.
16349 * character.c (Fstring): Check for size-calculation overflow.
16351 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
16352 unnecessary integer overflow. Check for size overflow.
16353 (encode_coding_object): Don't update size until xmalloc succeeds.
16355 * composite.c (get_composition_id): Check for overflow in glyph
16356 length calculations.
16358 Integer and memory overflow fixes for display code.
16359 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
16360 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
16361 (scrolling_window): Check for overflow in size calculations.
16362 (line_draw_cost, realloc_glyph_pool, add_row_entry):
16363 Don't assume glyph table len fits in int.
16364 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
16365 (row_table_size): Now ptrdiff_t, not int.
16366 (scrolling_window): Avoid overflow in size calculations.
16367 Don't update size until allocation succeeds.
16368 * fns.c (concat): Check for overflow in size calculations.
16369 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
16370 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
16371 (NEXT_ALMOST_PRIME_LIMIT): New constant.
16373 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
16374 (get_doc_string): Check for size calculation overflow.
16375 Don't update size until allocation succeeds.
16376 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
16377 EMACS_INT, where ptrdiff_t will do.
16378 (Fsubstitute_command_keys): Check for string overflow.
16380 * editfns.c (set_time_zone_rule): Don't assume environment length
16382 (message_length): Now ptrdiff_t, not int.
16383 (Fmessage_box): Don't update size until allocation succeeds.
16384 Don't assume message length fits in int.
16385 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
16387 * emacs.c (main): Do not reallocate argv, since there is a null at
16388 the end that can be overwritten, and this way there's no need to
16389 worry about size-calculation overflow.
16390 (sort_args): Check for size-calculation overflow.
16392 * eval.c (init_eval_once, grow_specpdl): Don't update size until
16394 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
16396 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
16397 (x_set_scroll_bar_width, x_figure_window_size):
16398 Check for integer overflow.
16399 (x_set_alpha): Do not assume XINT fits in int.
16401 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
16402 This is for the members text_lines, text_cols, total_lines, total_cols,
16403 where the system imposes an 'int' limit.
16405 * fringe.c (Fdefine_fringe_bitmap):
16406 Don't update size until alloc works.
16408 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
16409 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
16411 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
16412 Check for size-calculation overflow.
16413 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
16414 do, as we prefer signed integers.
16415 (id_to_widget.max_size, id_to_widget.used)
16416 (xg_store_widget_in_map, xg_remove_widget_from_map)
16417 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
16418 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
16419 Use and return ptrdiff_t, not int.
16420 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
16421 * gtkutil.h: Change prototypes to match the above.
16423 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
16424 are duplicate now that they've been promoted to lisp.h.
16425 (x_allocate_bitmap_record, x_alloc_image_color)
16426 (make_image_cache, cache_image, xpm_load):
16427 Don't update size until alloc is done.
16428 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
16430 Check for size calculation overflow.
16431 (ct_colors_allocated_max): New constant.
16432 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
16435 * keyboard.c (read_char, menu_bar_items, tool_bar_items)
16436 (read_char_x_menu_prompt, read_char_minibuf_menu_width)
16437 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
16438 Use ptrdiff_t, not int, to count maps.
16439 (read_char_minibuf_menu_prompt): Check for overflow in size
16440 calculations. Don't update size until allocation succeeds.
16441 Redo calculations to avoid overflow.
16442 * keyboard.h: Change prototypes to match the above.
16444 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
16446 (current_minor_maps): Check for size calculation overflow.

16468 (Fset_match_data): Don't assume list lengths fit in 'int'.
16470 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
16471 for command line length. Do not attempt to address one before the
16472 beginning of an array, as that's not portable.
16474 * term.c (max_frame_lines): Remove; unused.

16502 Check for size calculation overflow.
16503 (cache_face): Treat size calculation overflows as if they were
16504 memory exhaustion (the usual treatment), rather than aborting.
16506 * xfns.c (x_encode_text, x_set_name_internal)
16507 (Fx_change_window_property): Use ptrdiff_t, not int, to count
16508 sizes, since they can exceed INT_MAX in size. Check for size
16509 calculation overflow.
16511 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
16512 (xg_select): Check for size calculation overflow.
16513 Don't update size until alloc done.
16515 * xrdb.c (get_environ_db): Don't assume path length fits in int,
16516 as sprintf is limited to int lengths.
16518 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
16519 (X_LONG_MIN): New macros.
16520 Use them to make the following changes clearer.
16521 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
16522 This change doesn't affect the value now, but it may help remind
16523 future maintainers not to raise the value too much later.
16524 (SELECTION_QUANTUM): Remove, replacing with ...
16525 (selection_quantum): ... new function, which avoids overflow.
16527 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
16528 assumption that selection length fits in 'int'.
16529 (x_reply_selection_request, x_handle_selection_request)
16530 (x_get_window_property, receive_incremental_selection)

16545 Don't store size until memory allocation succeeds.
16546 (x_get_window_property): Plug memory leak on memory exhaustion.
16547 Don't double-block input; malloc is safe here. Don't assume 2**34
16548 - 4 fits in unsigned long. Add an xassert to check
16549 XGetWindowProperty overflow. Be more careful about overflow
16550 calculations, and distinguish size from memory overflow better.
16551 (receive_incremental_selection): When tracing, don't assume
16552 unsigned int is less than INT_MAX.
16553 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory

16556 in the range -65535 through -1 fit in an X unsigned short.
16557 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
16558 result parameters unless successful. Rely on cons_to_unsigned
16559 to report problems with elements; the old code wasn't right anyway.
16560 (x_check_property_data): Check for int overflow; we cannot use
16561 a wider type due to X limits.
16562 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

16594 * lisp.h (hash_lookup, hash_put):
16595 * minibuf.c (Ftest_completion):
16596 Use ptrdiff_t for hash table indexes, not int (which is too
16597 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
16598 32-bit --with-wide-int hosts).
16600 * charset.c (Fdefine_charset_internal): Check for integer overflow.
16601 Add a FIXME comment about memory leaks.

16609 with outlandish widths.
16610 * character.h (sanitize_tab_width): Rename from sanitize_width,
16611 now that we have two such functions. All uses changed.

16629 * xterm.c: Don't go over XClientMessageEvent limit.
16630 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
16631 (x_send_scroll_bar_event): Likewise. Check that the size does not
16632 exceed limits imposed by XClientMessageEvent, as well as the usual
16633 ptrdiff_t and size_t limits.
16635 * keyboard.c: Overflow, signedness and related fixes.
16636 (make_lispy_movement): Use same integer type in forward decl
16637 that is used in the definition.
16638 (read_key_sequence, keyremap_step):
16639 Change bufsize argument back to int, undoing my 2011-03-30 change.
16640 We prefer signed types, and int is wide enough here.
16641 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
16642 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
16643 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
16644 length, not size_t. Use ptrdiff_t for index, not int.
16645 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
16646 possibility of integer overflow.
16648 Overflow, signedness and related fixes for images.

16670 (lookup_image): Remove unnecessary tests.
16671 (xbm_image_p): Locals are now of int, not EMACS_INT,
16672 since parse_image_check makes sure they fit into int.
16673 (png_load, gif_load, svg_load_image):
16674 Prefer int to unsigned where either will do.
16675 (tiff_handler): New function, combining the cores of the
16676 old tiff_error_handler and tiff_warning_handler.
16677 This function is rewritten to use vsnprintf and thereby avoid
16678 stack buffer overflows. It uses only the features of vsnprintf
16679 that are common to both POSIX and native Microsoft.
16680 (tiff_error_handler, tiff_warning_handler): Use it.
16681 (tiff_load, gif_load, imagemagick_load_image):
16682 Don't assume :index value fits in 'int'.
16683 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
16684 (imagemagick_load_image): Check that crop parameters fit into
16685 the integer types that MagickCropImage accepts. Don't assume
16686 Vimagemagick_render_type has a nonnegative value. Don't assume
16687 size_t fits in 'long'.
16688 (gs_load): Use printmax_t to print the widest integers possible.

16701 handle_single_display_spec, not just 1 or zero.
16702 (handle_single_display_spec): If the display spec is of the form
16703 `(space ...)', and specifies display in the text area, return 2
16705 (try_cursor_movement): Check for the need to scroll more
16706 accurately, and prefer exact match for point under bidi.
16707 Don't advance `row' beyond the last row of the window.

16725 buffers, return left-to-right.
16726 (set_cursor_from_row): Consider candidate row a win if its glyph
16727 represents a newline and point is on that newline. Fixes cursor
16728 positioning on the newline at EOL of R2L text within L2R
16729 paragraph, and vice versa.
16730 (try_cursor_movement): Check continued rows, in addition to
16731 continuation rows. Fixes unwarranted scroll when point enters a
16732 continued line of R2L text within an L2R paragraph, or vice versa.
16733 (cursor_row_p): Consider the case of point being equal to
16734 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving

16763 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
16764 instead of CHAR_TO_BYTE. Fixes a crash when a completion
16765 candidate is selected by the mouse, and that candidate has a
16766 composed character under the mouse.
16768 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
16769 coordinates reported by pos-visible-in-window-p for a composed
16770 character in column zero.
16772 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

16778 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
16779 consider it a hit if to_charpos is anywhere in the range of the
16780 composed buffer positions.
16782 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
16784 * image.c (gif_load): Don't assume that each subimage has the same
16785 dimensions as the base image. Handle disposal method that is
16786 "undefined" by the gif spec (Bug#9335).
16788 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
16790 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

16796 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
16797 from an Org mode buffer to a Speedbar frame.
16799 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
16800 a composition, take its buffer position from IT->cmp_it.charpos.
16801 Fixes cursor positioning at the beginning of a line that begins
16802 with a composed character.
16804 2011-08-18 Eli Zaretskii <eliz@gnu.org>
16806 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
16807 character bidirectional type, use STRONG_L instead. Fixes crashes
16808 in a buffer produced by `describe-categories'.
16810 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
16811 members before the level stack, so they would be saved and
16812 restored when copying iterator state. Fixes incorrect reordering
16813 around TABs covered by display properties.
16815 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>

16841 Fix memory allocation problems in Cygwin build (Bug#9273).
16843 * unexcw.c ( __malloc_initialized): Declare external variable.
16844 (fixup_executable): Force the dumped emacs to reinitialize malloc.
16846 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):

16887 * xdisp.c (move_it_in_display_line_to): Don't invoke
16888 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
16889 ppos_it. Fixes vertical cursor motion when line beginning is
16890 covered by an image. (Bug#9296)
16892 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
16894 * nsterm.h (ns_run_ascript): Declare.
16895 (NSAPP_DATA2_RUNASSCRIPT): Define.
16897 * nsfns.m (as_script, as_result, as_status): New static variables.
16898 (ns_run_ascript): New function.
16899 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
16900 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
16901 the event loop. Get status from as_status (Bug#7276).
16903 * nsterm.m (sendEvent): If event is NSApplicationDefined and
16904 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
16905 the event loop (Bug#7276).
16907 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
16909 * gnutls.c (QCgnutls_bootprop_priority)
16910 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
16911 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
16912 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
16913 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
16914 (QCgnutls_bootprop_verify_hostname_error)
16915 (QCgnutls_bootprop_callbacks_verify): Rename from
16916 Qgnutls_bootprop_..., all uses changed.
16918 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
16921 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
16923 * xfaces.c (Qframe_set_background_mode): Now static.
16924 * dispextern.h (Qframe_set_background_mode): Remove decl.
16926 * process.c (Fnetwork_interface_info): Declare local only if needed.
16928 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
16930 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
16931 (Fnetwork_interface_list): Allocate in increments of bytes instead
16932 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
16933 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
16935 (struct ifflag_def): notrailers is smart on OSX.
16936 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
16937 Get hardware address with getifaddrs if available.
16939 2011-08-12 Eli Zaretskii <eliz@gnu.org>
16941 * xdisp.c (iterate_out_of_display_property): xassert that
16942 IT->position is set to within IT->object's boundaries. Break from
16943 the loop as soon as EOB is reached; avoids infloops in redisplay
16944 when IT->position is set up wrongly due to some bug.
16945 Set IT->current to match the bidi iterator unconditionally.
16946 (push_display_prop): Allow GET_FROM_STRING as IT->method on
16947 entry. Force push_it to save on the stack the current
16948 buffer/string position, to be restored by pop_it. Fix flags in
16949 the iterator structure wrt the object coming from a display
16950 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
16951 properties. (Bug#9284)
16953 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
16955 * fontset.c (fontset_get_font_group): Add proper type checks.
16958 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
16960 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
16961 and LC_VERSION_MIN_MACOSX.
16962 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
16963 (dump_it) [LC_FUNCTION_STARTS]: Use it.
16965 2011-08-08 Eli Zaretskii <eliz@gnu.org>
16967 * xdisp.c (forward_to_next_line_start): Allow to use the
16968 no-display-properties-and-no-overlays under bidi display.
16969 Set disp_pos in the bidi iterator to avoid searches for display
16970 properties and overlays.
16972 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
16974 * editfns.c (Fset_time_zone_rule): Document relationship with the
16977 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
16978 the font entity extracted from the cache (Bug#8109).
16980 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
16982 * composite.c (autocmp_chars): Don't reset point. That is done by
16983 restore_point_unwind (Bug#5984).
16985 2011-08-07 Juri Linkov <juri@jurta.org>
16987 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
16988 to show the arg `TIME' instead of `TIMEVAL'.
16990 2011-08-06 Eli Zaretskii <eliz@gnu.org>
16992 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
16993 display property strides EOL and includes a newline, as in
16994 longlines-mode. (Bug#9254)
16995 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
16996 word-wrap under bidirectional display. (Bug#9224)
16998 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
16999 is non-zero, even if the data buffer is NULL. Fixes a crash in
17000 vertical-motion with longlines-mode. (Bug#9254)
17002 2011-08-05 Eli Zaretskii <eliz@gnu.org>
17004 * bidi.c <bidi_cache_total_alloc>: Now static.
17005 (bidi_initialize): Initialize bidi_cache_total_alloc.
17007 * xdisp.c (display_line): Release buffer allocated for shelved bidi
17010 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
17011 amount allocated this far in `bidi_cache_total_alloc'.
17012 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
17013 non-zero, only free the data buffer without restoring the cache
17014 contents. All callers changed.
17016 * dispextern.h (bidi_unshelve_cache): Update prototype.
17018 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
17019 (move_it_in_display_line, move_it_to)
17020 (move_it_vertically_backward, move_it_by_lines): Replace the call
17021 to xfree to an equivalent call to bidi_unshelve_cache.
17022 (move_it_in_display_line_to): Fix logic of returning
17023 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
17025 2011-08-05 Eli Zaretskii <eliz@gnu.org>
17027 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
17028 came from a string character with a `cursor' property. (Bug#9229)
17030 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
17032 * Makefile.in (LIB_PTHREAD): New variable.
17033 (LIBES): Add LIB_PTHREAD (Bug#9216).
17035 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
17036 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
17038 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
17040 * regex.c (re_iswctype): Remove some redundant boolean conversions.
17042 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
17044 * xterm.c (x_find_topmost_parent): New function.
17045 (x_set_frame_alpha): Find topmost parent window with
17046 x_find_topmost_parent and set the property there also (bug#9181).
17047 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
17049 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
17051 * callproc.c (Fcall_process): Avoid vfork clobbering
17052 the local vars buffer, coding_systems, current_dir.
17054 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
17056 * keymap.c (Fmake_composed_keymap): Move to subr.el.
17058 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
17060 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
17061 so that it is not optimized away.
17063 * xdisp.c (compute_display_string_pos): Remove unused local.
17065 2011-08-02 Eli Zaretskii <eliz@gnu.org>
17067 Fix slow cursor motion and scrolling in large buffers with
17068 selective display, like Org Mode buffers. (Bug#9218)
17070 * dispextern.h (struct bidi_it): New member disp_prop_p.
17072 * xdisp.c: Remove one-slot cache of display string positions.
17073 (compute_display_string_pos): Accept an additional argument
17074 DISP_PROP_P; callers changed. Scan at most 5K characters forward
17075 for a display string or property. If found, set DISP_PROP_P
17078 * bidi.c (bidi_fetch_char): Accept an additional argument
17079 DISP_PROP_P, and pass it to compute_display_string_pos.
17080 Only handle text covered by a display string if DISP_PROP_P is returned
17081 non-zero. All callers of bidi_fetch_char changed.
17083 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
17085 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
17087 2010-12-03 Don March <don@ohspite.net>
17089 * keymap.c (Fdefine_key): Fix non-prefix key error message when
17090 last character M-[char] is translated to ESC [char] (bug#7541).
17092 2011-08-02 Kenichi Handa <handa@m17n.org>
17094 * lisp.h (uniprop_table): Extern it.
17096 * chartab.c (uniprop_table): Make it non-static.
17098 2011-08-01 Eli Zaretskii <eliz@gnu.org>
17100 * xdisp.c (forward_to_next_line_start): Accept additional argument
17101 BIDI_IT_PREV, and store into it the state of the bidi iterator had
17103 (reseat_at_next_visible_line_start): Use the bidi iterator state
17104 returned by forward_to_next_line_start to restore the state of
17105 it->bidi_it after backing up to previous newline. (Bug#9212)
17107 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
17109 * regex.c (re_comp): Protoize.
17110 (re_exec): Fix return type.
17111 (regexec): Fix type of `ret'. (Bug#9203)
17113 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17115 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
17116 This is needed if max-image-size is a floating-point number.
17118 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
17120 * print.c (print_object): Print empty symbol as ##.
17122 * lread.c (read1): Read ## as empty symbol.
17124 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
17126 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
17127 setting frame foreground color (Bug#9175).
17128 (x_set_background_color): Likewise.
17130 * nsmenu.m (-setText): Size tooltip dimensions precisely to
17131 contents (Bug#9176).
17132 (EmacsTooltip -init): Remove bezels and add shadows to
17135 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
17136 or scroll bar (Bug#8470).
17138 * nsfont.m (nsfont_open): Remove assignment to voffset and
17139 unnecessary vars hshink, expand, hd, full_height, min_height.
17140 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
17142 * nsterm.h (nsfont_info): Remove voffset field.
17144 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
17146 Implement strike-through and overline on NextStep (Bug#8863).
17148 * nsfont.m (nsfont_open): Use underline position provided by font,
17149 instead of hard-coded value of 2.
17150 (nsfont_draw): Call ns_draw_text_decoration instead.
17152 * nsterm.h: Add declaration for ns_draw_text_decoration.
17154 * nsterm.m (ns_draw_text_decoration): New function for drawing
17155 underline, overline, and strike-through.
17156 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
17157 ns_draw_text_decoration. Change treatment of cursor drawing to
17158 accommodate underlining, etc.
17160 2011-07-28 Eli Zaretskii <eliz@gnu.org>
17162 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
17165 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17167 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
17168 Without this fix, if a signal arrives just after memory fills up,
17169 'malloc' might be invoked reentrantly.
17171 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
17172 In other words, assume that every image size is allowed, on non-X
17173 hosts. This assumption is probably wrong, but it lets Emacs compile.
17175 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
17177 * regex.c (re_iswctype): Convert return values to boolean.
17179 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
17181 * xdisp.c (compute_display_string_pos): Don't use cached display
17182 string position if the buffer had its restriction changed.
17185 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17187 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
17189 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
17191 Integer signedness and overflow and related fixes. (Bug#9079)
17193 * bidi.c: Integer size and overflow fixes.
17194 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
17195 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
17196 (bidi_cache_find_level_change, bidi_cache_ensure_space)
17197 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
17198 (bidi_find_other_level_edge):
17199 Use ptrdiff_t instead of EMACS_INT where either will do.
17200 This works better on 32-bit hosts configured --with-wide-int.
17201 (bidi_cache_ensure_space): Check for size-calculation overflow.
17202 Use % rather than repeated addition, for better worst-case speed.
17203 Don't set bidi_cache_size until after xrealloc returns, because it
17205 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
17206 (bidi_cache_ensure_space): Also check that the bidi cache size
17207 does not exceed that of the largest Lisp string or buffer. See Eli
17208 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
17210 * alloc.c (__malloc_size_t): Remove.
17211 All uses replaced by size_t. See Andreas Schwab's note
17212 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
17214 * image.c: Improve checking for integer overflow.
17215 (check_image_size): Assume that f is nonnull, since
17216 it is always nonnull in practice. This is one less thing to
17217 worry about when checking for integer overflow later.
17218 (x_check_image_size): New function, which checks for integer
17219 overflow issues inside X.
17220 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
17221 This removes the need for a memory_full check.
17222 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
17223 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
17224 (xbm_read_bitmap_data): Change locals back to 'int', since
17225 their values must fit in 'int'.
17226 (xpm_load_image, png_load, tiff_load):
17227 Invoke x_create_x_image_and_pixmap earlier,
17228 to avoid much needless work if the image is too large.
17229 (tiff_load): Treat overly large images as if
17230 x_create_x_image_and_pixmap failed, not as malloc failures.
17231 (gs_load): Use x_check_image_size.
17233 * gtkutil.c: Omit integer casts.
17234 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
17235 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
17237 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
17239 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
17240 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
17241 would wrongly return t on a 64-bit host.
17243 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
17244 The plain *_OVERFLOW macros run afoul of GCC bug 49705
17245 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
17246 and therefore cause GCC to emit a bogus diagnostic in some cases.
17248 * image.c: Integer signedness and overflow and related fixes.
17249 This is not an exhaustive set of fixes, but it's time to
17250 record what I've got.
17251 (lookup_pixel_color, check_image_size): Remove redundant decls.
17252 (check_image_size): Don't assume that arbitrary EMACS_INT values
17253 fit in 'int', or that arbitrary 'double' values fit in 'int'.
17254 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
17255 (tiff_load, imagemagick_load_image):
17256 Check for overflow in size calculations.
17257 (x_create_x_image_and_pixmap): Remove unnecessary test for
17258 xmalloc returning NULL; that can't happen.
17259 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
17260 (xpm_color_bucket): Use better integer hashing function.
17261 (xpm_cache_color): Don't possibly over-allocate memory.
17262 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
17263 (gif_memory_source):
17264 Use ptrdiff_t, not int or size_t, to record sizes.
17265 (png_load): Don't assume values greater than 2**31 fit in 'int'.
17266 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
17267 either works, as we prefer signed integers.
17268 (tiff_read_from_memory, tiff_write_from_memory):
17269 Return tsize_t, not size_t, since that's what the TIFF API wants.
17270 (tiff_read_from_memory): Don't fail simply because the read would
17271 go past EOF; instead, return a short read.
17272 (tiff_load): Omit no-longer-needed casts.
17273 (Fimagemagick_types): Don't assume size fits into 'int'.
17275 Improve hashing quality when configured --with-wide-int.
17276 * fns.c (hash_string): New function, taken from sxhash_string.
17277 Do not discard information about ASCII character case; this
17278 discarding is no longer needed.
17279 (sxhash-string): Use it. Change sig to match it. Caller changed.
17280 * lisp.h: Declare it.
17281 * lread.c (hash_string): Remove, since we now use fns.c's version.
17282 The fns.c version returns a wider integer if --with-wide-int is
17283 specified, so this should help the quality of the hashing a bit.
17285 * emacs.c: Integer overflow minor fix.
17286 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
17287 Define only if GNU_LINUX.
17288 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
17290 * dispnew.c: Integer signedness and overflow fixes.
17291 Remove unnecessary forward decls, that were a maintenance hassle.
17292 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
17294 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
17295 (scrolling_window): Use ptrdiff_t, not int, for byte count.
17296 (prepare_desired_row, line_draw_cost):
17297 Use int, not unsigned, where either works.
17298 (save_current_matrix, restore_current_matrix):
17299 Use ptrdiff_t, not size_t, where either works.
17300 (init_display): Check for overflow more accurately, and without
17301 relying on undefined behavior.
17303 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
17304 Remove, replacing with the new symbols in lisp.h. All uses changed.
17305 * fileio.c (make_temp_name):
17306 * filelock.c (lock_file_1, lock_file):
17307 * xdisp.c (message_dolog):
17308 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
17309 Use pMd etc. instead.
17310 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
17311 replacing the pWIDE etc. symbols removed from editfns.c.
17313 * keyboard.h (num_input_events): Now uintmax_t.
17314 This is (very slightly) less likely to mess up due to wraparound.
17317 * buffer.c: Integer signedness fixes.
17318 (alloc_buffer_text, enlarge_buffer_text):
17319 Use ptrdiff_t rather than size_t when either will do, as we prefer
17322 * alloc.c: Integer signedness and overflow fixes.
17323 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
17324 (__malloc_size_t): Default to size_t, not to int.
17325 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
17326 (Fgarbage_collect, mark_object_loop_halt, mark_object):
17327 Prefer ptrdiff_t to size_t when either would do, as we prefer
17329 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
17330 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
17331 Now const. Initialize with values that are in range even if char
17333 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
17334 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
17335 These functions do the right thing with sizes > 2**32.
17336 (check_depth): Now ptrdiff_t, not int.
17337 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
17338 Adjust to new way of storing sizes. Check for size overflow bugs
17340 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
17341 slightly wrong anyway, as it missed one instance of
17342 XMALLOC_OVERRUN_CHECK_OVERHEAD.
17343 (refill_memory_reserve): Omit needless cast to size_t.
17344 (mark_object_loop_halt): Mark as externally visible.
17346 * xselect.c: Integer signedness and overflow fixes.
17347 (Fx_register_dnd_atom, x_handle_dnd_message):
17348 Use ptrdiff_t, not size_t, since we prefer signed.
17349 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
17350 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
17351 x_dnd_atoms_size and x_dnd_atoms_length.
17353 * doprnt.c: Prefer signed to unsigned when either works.
17355 * doprnt.c (doprnt):
17357 * xdisp.c (vmessage):
17358 Use ptrdiff_t, not size_t, when using or implementing doprnt,
17359 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
17360 prefer signed arithmetic to avoid comparison confusion.
17361 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
17362 but is a bit tricky.
17364 Assume freestanding C89 headers, string.h, stdlib.h.
17365 * data.c, doprnt.c, floatfns.c, print.c:
17366 Include float.h unconditionally.
17367 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
17368 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
17369 * regex.c: Likewise for stddef.h, string.h.
17370 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
17371 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
17372 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
17373 (STDC_HEADERS): Remove obsolete defines.
17374 * sysdep.c: Include limits.h unconditionally.
17376 Assume support for memcmp, memcpy, memmove, memset.
17377 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
17378 * regex.c (memcmp, memcpy):
17379 Remove; we assume C89 now.
17381 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
17382 (__malloc_safe_bcopy): Remove; no longer needed.
17384 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
17385 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
17386 well either way, and we prefer signed to unsigned.
17388 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
17390 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
17391 closes the connection while we're reading (bug#9182).
17393 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
17395 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
17396 are specified (Bug#9168).
17398 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
17400 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
17401 Found by GCC static checking and --with-wide-int on a 32-bit host.
17403 2011-07-25 Eli Zaretskii <eliz@gnu.org>
17405 * xdisp.c (compute_display_string_pos): Fix logic of caching
17406 previous display string position. Initialize cached_prev_pos to
17407 -1. Fixes slow-down at the beginning of a buffer.
17409 2011-07-24 Eli Zaretskii <eliz@gnu.org>
17411 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
17412 for attrs[LFACE_FONTSET_INDEX].
17414 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
17416 * xml.c (parse_region): Remove unused local
17417 that was recently introduced.
17419 2011-07-23 Eli Zaretskii <eliz@gnu.org>
17421 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
17422 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
17424 * xdisp.c (move_it_in_display_line_to): Record the best matching
17425 position for TO_CHARPOS while scanning the line, and restore it on
17426 exit if none of the characters scanned was an exact match.
17427 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
17428 when exact match is impossible due to invisible text, and the
17429 lines are truncated.
17431 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
17433 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
17436 2011-07-22 Eli Zaretskii <eliz@gnu.org>
17438 Fix a significant slow-down of cursor motion with C-n, C-p,
17439 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
17440 auto-repeat under bidi redisplay in fontified buffers.
17441 * xdisp.c (compute_stop_pos_backwards): New function.
17442 (next_element_from_buffer): Call compute_stop_pos_backwards to
17443 find a suitable prev_stop when we find ourselves before
17445 (reseat): Don't look for prev_stop, as that could mean a very long
17447 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
17448 <cached_disp_overlay_modiff>: Cache for last found display string
17450 (compute_display_string_pos): Return the cached position if asked
17451 about the same buffer in the same area of character positions, and
17452 the buffer wasn't changed since the time the display string
17453 position was cached.
17455 2011-07-22 Eli Zaretskii <eliz@gnu.org>
17457 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
17458 is an integer, which is important for empty lines. (Bug#9149)
17460 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
17462 * frame.c (Fmodify_frame_parameters): In tty case, update the
17463 default face if necessary (Bug#4238).
17465 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
17467 * editfns.c (Fstring_to_char): No need to explain what a character
17468 is in the docstring (Bug#6576).
17470 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
17472 * xml.c (parse_region): Make sure we always return a tree.
17474 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
17476 * xml.c (parse_region): If a document contains only comments,
17479 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
17481 * xml.c (make_dom): Return comments, too.
17483 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
17486 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
17487 and the surrounding thread.
17488 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
17489 rather than fgets, and retry after EINTR. Otherwise, 'emacs
17490 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
17492 * s/openbsd.h (BROKEN_SIGIO): Define.
17493 * unexelf.c (unexec) [__OpenBSD__]:
17494 Don't update the .mdebug section of the Alpha COFF symbol table.
17496 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
17498 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
17501 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
17503 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
17504 This fixes some race conditions on the permissions of any newly
17507 * alloc.c (valid_pointer_p): Use pipe, not open.
17508 This fixes some permissions issues when debugging.
17510 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
17511 If fchown fails to set both uid and gid, try to set just gid,
17512 as that is sometimes allowed. Adjust the file's mode to eliminate
17513 setuid or setgid bits that are inappropriate if fchown fails.
17515 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
17517 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
17518 to compare Lisp_Objects.
17519 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
17520 global_gnutls_log_level, don't mistake it for a Lisp_Object.
17521 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
17523 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
17525 * lread.c (read_integer): Unread even EOF character.
17526 (read1): Likewise. Properly record start position of symbol.
17528 * lread.c (read1): Read `#:' as empty uninterned symbol if no
17529 symbol character follows.
17531 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
17533 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
17534 This works around a problem with the previous change to Fcopy_file.
17535 Recent glibc declares fchown with __attribute__((warn_unused_result)),
17536 and without this change, GCC might complain about discarding
17537 fchown's return value.
17539 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
17541 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
17543 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
17545 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
17547 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
17549 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
17550 it's used from the C level.
17552 * process.c: Use the same condition for POLL_FOR_INPUT in both
17553 keyboard.c and process.c (bug#1858).
17555 2011-07-09 Lawrence Mitchell <wence@gmx.li>
17557 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
17558 (Fgnutls_boot): Use it.
17560 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
17562 * doc.c (Fsubstitute_command_keys): Revert last change.
17564 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
17566 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
17567 quotes the next character, and doesn't affect other longer
17568 sequences (bug#8935).
17570 * lread.c (syms_of_lread): Clarify that is isn't only
17571 `eval-buffer' and `eval-defun' that's affected by
17572 `lexical-binding' (bug#8460).
17574 2011-07-15 Eli Zaretskii <eliz@gnu.org>
17576 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
17577 bidi redisplay when a line includes both an image and is truncated.
17579 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
17581 Fix minor problems found by static checking.
17582 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
17583 (elsz): Now a signed constant, not a size_t var. We prefer signed
17584 types to unsigned, to avoid integer comparison confusion. Without
17585 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
17586 "cannot optimize loop, the loop counter may overflow", a symptom
17588 * indent.c (Fvertical_motion): Mark locals as initialized.
17589 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
17591 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
17593 * search.c (Fre_search_backward): Mention `case-fold-search' in
17594 all the re_search_* functions (bug#8138).
17596 * keyboard.c (Fopen_dribble_file): Document when the file is

17607 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
17608 (reseat_to_string): Initialize bidi_it->string.s and
17609 bidi_it->string.schars.
17610 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
17611 NULL (avoids a crash in bidi_paragraph_init).
17612 Initialize itb.string.lstring.
17613 (init_iterator): Call bidi_init_it only of a valid
17614 buffer position was specified. Initialize paragraph_embedding to
17616 (reseat_to_string): Initialize the bidi iterator.
17617 (display_string): If we need to ignore text properties of
17618 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
17619 original value of -1 will not work with bidi.)
17620 (compute_display_string_pos): First arg is now struct
17621 `text_pos *'; all callers changed. Support display properties on
17623 (compute_display_string_end): Support display properties on Lisp
17625 (init_iterator, reseat_1, reseat_to_string): Initialize the
17626 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
17627 when iterating on a string not from display properties).
17628 (compute_display_string_pos, compute_display_string_end):
17629 Fix calculation of the object to scan. Fixes an error when using
17631 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
17632 base_level_stop; instead, set base_level_stop to BEGV.
17633 Fixes crashes in vertical-motion.
17634 (next_element_from_buffer): Improve commentary for when
17635 the iterator is before prev_stop.
17636 (init_iterator): Initialize bidi_p from the default value of
17637 bidi-display-reordering, not from buffer-local value. Use the
17638 buffer-local value only if initializing for buffer iteration.
17639 (handle_invisible_prop): Support invisible properties on strings
17640 that are being bidi-reordered.
17641 (set_iterator_to_next): Support bidi reordering of C strings and
17643 (next_element_from_string): Support bidi reordering of Lisp
17645 (handle_stop_backwards): Support Lisp strings as well.
17646 (display_string): Support display of R2L glyph rows.
17647 Use IT_STRING_CHARPOS when displaying from a Lisp string.
17648 (init_iterator): Don't initialize it->bidi_p for strings
17650 (reseat_to_string): Initialize it->bidi_p for strings here.
17651 (next_element_from_string, next_element_from_c_string)
17652 (next_element_from_buffer): Add xassert's for correspondence
17653 between IT's object being iterated and it->bidi_it.string
17655 (face_before_or_after_it_pos): Support bidi iteration.
17656 (next_element_from_c_string): Handle the case of the first string
17657 character that is not the first one in the visual order.
17658 (get_visually_first_element): New function, refactored from common
17659 parts of next_element_from_buffer, next_element_from_string, and
17660 next_element_from_c_string.
17661 (tool_bar_lines_needed, redisplay_tool_bar)
17662 (display_menu_bar): Force left-to-right direction. Add a FIXME
17663 comment for making that be controlled by a user option.
17664 (push_it, pop_it): Save and restore the state of the
17665 bidi iterator. Save and restore the bidi_p flag.
17666 (pop_it): Iterate out of display property for string iteration as
17668 (iterate_out_of_display_property): Support iteration over strings.
17669 (handle_single_display_spec): Set up it->bidi_it for iteration
17670 over a display string, and call bidi_init_it.
17671 (handle_single_display_spec, next_overlay_string)
17672 (get_overlay_strings_1, push_display_prop): Set up the bidi
17673 iterator for displaying display or overlay strings.
17674 (forward_to_next_line_start): Don't use the shortcut if
17676 (back_to_previous_visible_line_start): If handle_display_prop
17677 pushed the iterator stack, restore the internal state of the bidi
17678 iterator by calling bidi_pop_it same number of times.
17679 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
17680 and we are bidi-iterating, don't decrement the iterator position;
17681 instead, set the first_elt flag in the bidi iterator, to produce
17683 (reseat_1): Remove redundant setting of string_from_display_prop_p.
17684 (push_display_prop): xassert that we are iterating a buffer.
17685 (push_it, pop_it): Save and restore paragraph_embedding member.
17686 (handle_single_display_spec, next_overlay_string)
17687 (get_overlay_strings_1, reseat_1, reseat_to_string)
17688 (push_display_prop): Set up the `unibyte' member of bidi_it.string
17689 correctly. Don't assume unibyte strings are not bidi-reordered.
17690 (compute_display_string_pos)
17691 (compute_display_string_end): Fix handling the case of C string.
17692 (push_it, pop_it): Save and restore from_disp_prop_p.
17693 (handle_single_display_spec, push_display_prop): Set the
17694 from_disp_prop_p flag.
17695 (get_overlay_strings_1): Reset the from_disp_prop_p flag.

17697 popping after iteration over a string that came from a display
17698 property. Fix a typo in popping stretch info. Add an assertion
17699 for verifying that the iterator position is in sync with the bidi
17701 (handle_single_display_spec, get_overlay_strings_1)
17702 (push_display_prop): Fix initialization of paragraph direction for
17703 string when that of the parent object is not yet determined.
17704 (reseat_1): Call bidi_init_it to resync the bidi
17705 iterator with IT's position. (Bug#7616)
17706 (find_row_edges): If ROW->start.pos gives position
17707 smaller than min_pos, use it as ROW->minpos. (Bug#7616)
17708 (handle_stop, back_to_previous_visible_line_start, reseat_1):
17709 Reset the from_disp_prop_p flag.
17710 (SAVE_IT, RESTORE_IT): New macros.
17711 (pos_visible_p, face_before_or_after_it_pos)
17712 (back_to_previous_visible_line_start)
17713 (move_it_in_display_line_to, move_it_in_display_line)
17714 (move_it_to, move_it_vertically_backward, move_it_by_lines)
17715 (try_scrolling, redisplay_window, display_line): Use them when
17716 saving a temporary copy of the iterator and restoring it back.
17717 (back_to_previous_visible_line_start, reseat_1)
17718 (init_iterator): Empty the bidi cache "stack".
17719 (move_it_in_display_line_to): If iterator ended up at
17720 EOL, but we never saw any buffer positions smaller than
17721 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
17722 motion in bidi-reordered lines.
17723 (move_it_in_display_line_to): Record prev_method and prev_pos
17724 immediately before the call to set_iterator_to_next. Fixes cursor
17725 motion in bidi-reordered lines with stretch glyphs and strings
17726 displayed in margins. (Bug#8133) (Bug#8867)
17727 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
17729 (pos_visible_p): Support positions in bidi-reordered lines.
17730 Save and restore bidi cache.
17732 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.
17733 (bidi_paragraph_info): Delete unused struct.
17734 (bidi_cache_idx, bidi_cache_last_idx): Declare EMACS_INT.
17735 (bidi_cache_start): New variable.
17736 (bidi_cache_reset): Reset bidi_cache_idx to bidi_cache_start, not
17738 (bidi_cache_fetch_state, bidi_cache_search)
17739 (bidi_cache_find_level_change, bidi_cache_iterator_state)
17740 (bidi_cache_find, bidi_peek_at_next_level)

17744 (bidi_fetch_char): Accept new argument STRING; all callers
17745 changed. Support iteration over a string. Support strings with
17746 display properties. Support unibyte strings. Fix the type of
17747 `len' according to what STRING_CHAR_AND_LENGTH expects.
17748 (bidi_paragraph_init, bidi_resolve_explicit_1)
17749 (bidi_resolve_explicit, bidi_resolve_weak)
17750 (bidi_level_of_next_char, bidi_move_to_visually_next):
17751 Support iteration over a string.
17752 (bidi_set_sor_type, bidi_resolve_explicit_1)
17753 (bidi_resolve_explicit, bidi_type_of_next_char): ignore_bn_limit
17754 can now be zero (for strings); special values 0 and -1 were
17755 changed to -1 and -2, respectively.
17756 (bidi_char_at_pos): New function.
17757 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak):
17758 Call it instead of FETCH_MULTIBYTE_CHAR.
17759 (bidi_move_to_visually_next): Abort if charpos or bytepos were not
17760 initialized to valid values.
17761 (bidi_init_it): Don't initialize charpos and bytepos with invalid
17763 (bidi_level_of_next_char): Allow the sentinel "position" to pass
17764 the test for valid cached positions. Fix the logic for looking up

17843 2011-07-13 Paul Eggert <eggert@cs.ucla.edu>
17845 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
17846 The old code sometimes used this field without initializing it.
17848 * alloc.c (gc_sweep): Don't read past end of array.
17849 In theory, the old code could also have corrupted Emacs internals,
17850 though it'd be very unlikely.

18113 (clone_per_buffer_values): Don't assume that
18114 sizeof (struct buffer) is a multiple of sizeof (Lisp_Object).
18115 This isn't true in general, and it's particularly not true
18116 if Emacs is configured with --with-wide-int.
18117 * buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
18118 New macros, used in the buffer.c change.

18154 Random fixes. E.g., (random) never returned negative values.
18155 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
18156 subseconds part to the entropy, as that's a bit more random.
18157 Prefer signed to unsigned, since the signedness doesn't matter and
18158 in general we prefer signed. When given a limit, use a
18159 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
18160 latter isn't right if USE_2_TAGS_FOR_INTS.
18161 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
18162 not 0..VALMASK. Don't discard "excess" bits that random () returns.

18174 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
18175 This is more efficient than Ffile_directory_p and avoids a minor race.
18177 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
18179 * buffer.c (Foverlay_put): Say what the return value is
18182 * fileio.c (barf_or_query_if_file_exists): Check first if the file
18183 is a directory before asking whether to use the file name
18185 (barf_or_query_if_file_exists): Make the "File is a directory"
18186 error be more correct.
18188 * fns.c (Frequire): Remove the mention of the .gz files, since
18189 that's installation-specific, but keep the mention of
18190 `get-load-suffixes'.

18194 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

18202 Qgnutls_bootprop_verify_error (which is no longer used).
18204 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
18205 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
18206 Also (re)move comments that are misplaced or no longer relevant.

18307 * eval.c (struct backtrace): Simplify and port the data structure.
18308 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
18309 signed bit field, as this assumption is not portable and it makes
18310 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
18311 "char debug_on_exit : 1" as this is not portable either; instead,
18312 use the portable "unsigned int debug_on_exit : 1". Remove unused
18313 member evalargs. Remove obsolete comments about cc bombing out.

18387 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
18388 and use min_width/height from frames size_hint to set
18389 min_width/height (Bug#8919).

18482 (PRINTPREPARE, printchar, strout):
18483 Don't set size unless allocation succeeds.
18485 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
18486 for sizes. Check for string overflow more accurately.

18503 (read1): Check for integer overflow in radices, and in
18504 read-circle numbers.
18505 (read_escape): Avoid int overflow.
18506 (Fload, openp, read_buffer_size, read1)
18507 (substitute_object_recurse, read_vector, read_list, map_obarray):

18548 on undefined behavior with wrong number of arguments.
18549 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
18550 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
18551 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
18552 since we're not interested in debugging glyphs with old libraries.
18553 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
18554 GCC 4.6.0's static checking.
18556 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>

18595 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
18596 (x_session_initialize): Do not assume string length fits in int.
18598 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.

18644 Don't assume pid_t and time_t fit in unsigned long.
18645 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
18646 (current_lock_owner): Prefer signed type for sizes.
18647 Use memcpy, not strncpy, where memcpy is what is really wanted.
18648 Don't assume (via atoi) that time_t and pid_t fit in int.
18649 Check for time_t and/or pid_t out of range, e.g., via a network share.
18650 Don't alloca where an auto var works fine.
18652 * fileio.c: Fix some integer overflow issues.
18653 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
18654 Don't assume string length fits in int.
18655 (directory_file_name): Don't assume string length fits in long.
18656 (make_temp_name): Don't assume pid fits in int, or that its print
18657 length is less than 20.
18659 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
18661 * coding.c (make_subsidiaries): Don't assume string length fits in int.
18663 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
18665 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
18666 We prefer signed integers, even for size calculations.
18668 * emacs.c: Don't assume string length fits in 'int'.
18669 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
18670 (main): Don't invoke strlen when not needed.
18672 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
18673 (XD_DEBUG_MESSAGE): Don't waste a byte.
18675 * callproc.c (getenv_internal_1, getenv_internal)
18676 (Fgetenv_internal):
18677 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
18679 * lread.c (invalid_syntax): Omit length argument.
18680 All uses changed. This doesn't fix a bug, but it simplifies the
18681 code away from its former Hollerith-constant appearance, and it's
18682 one less 'int' to worry about when looking at integer-overflow issues.
18683 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
18685 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
18686 This didn't break anything, but it didn't help either.
18687 It's confusing to put a bogus integer in a place where the actual
18688 value does not matter.
18689 (LIST_END_P): Remove unused macro and its bogus comment.
18690 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
18692 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
18693 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
18695 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
18696 We prefer signed types, and the value cannot exceed the EMACS_INT
18697 range anyway (because otherwise the length would not be representable).
18698 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
18699 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
18700 This avoids a GCC warning when WIDE_EMACS_INT.
18702 * indent.c (sane_tab_width): New function.
18703 (current_column, scan_for_column, Findent_to, position_indentation)
18704 (compute_motion): Use it. This is just for clarity.
18705 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
18707 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
18709 * lisp.h (lint_assume): New macro.
18710 * composite.c (composition_gstring_put_cache):
18711 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
18713 * editfns.c, insdel.c:
18714 Omit unnecessary forward decls, to simplify future changes.
18716 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
18718 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
18720 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
18721 Use much-faster test for byte-length change.
18722 Don't assume string byte-length fits in 'int'.
18723 Check that character arg fits in 'int'.
18724 (mapcar1): Declare byte as byte, for clarity.
18726 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
18728 * fns.c (concat): Catch string overflow earlier.
18729 Do not rely on integer wraparound.
18731 * dispextern.h (struct it.overlay_strings_charpos)
18732 (struct it.selective): Now EMACS_INT, not int.
18733 * xdisp.c (forward_to_next_line_start)
18734 (back_to_previous_visible_line_start)
18735 (reseat_at_next_visible_line_start, next_element_from_buffer):
18736 Don't arbitrarily truncate the value of 'selective' to int.
18738 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
18740 * composite.c: Don't truncate sizes to 'int'.
18741 (composition_gstring_p, composition_reseat_it)
18742 (composition_adjust_point): Use EMACS_INT, not int.
18743 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
18744 not EMACS_UINT, for indexes.
18746 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
18748 * buffer.c: Include <verify.h>.
18749 (struct sortvec.priority, struct sortstr.priority):
18750 Now EMACS_INT, not int.
18751 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
18752 (struct sortstr.size, record_overlay_string)
18753 (struct sortstrlist.size, struct sortlist.used):
18754 Don't truncate size to int.
18755 (record_overlay_string): Check for size-calculation overflow.
18756 (init_buffer_once): Check at compile-time, not run-time.
18758 2011-06-22 Jim Meyering <meyering@redhat.com>
18760 Don't leak an XBM-image-sized buffer
18761 * image.c (xbm_load): Free the image buffer after using it.
18763 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
18766 * composite.c (find_automatic_composition): Omit needless 'return 0;'
18767 that Sun C diagnosed.
18768 * fns.c (secure_hash): Fix pointer signedness issue.
18769 * intervals.c (static_offset_intervals): New function.
18770 (offset_intervals): Use it.
18772 2011-06-21 Leo Liu <sdl.web@gmail.com>
18775 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
18778 * fns.c (secure_hash): Rename from crypto_hash_function and change
18779 the first arg to accept symbols.
18780 (Fsecure_hash): New primitive.
18781 (syms_of_fns): New symbols.
18783 2011-06-20 Deniz Dogan <deniz@dogan.se>
18785 * process.c (Fset_process_buffer): Clarify return value in
18788 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
18790 * dispnew.c (add_window_display_history): Use BVAR.
18792 * xdisp.c (debug_method_add): Use BVAR.
18793 (check_window_end, dump_glyph_matrix, dump_glyph)
18794 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
18796 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
18799 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
18800 check till after the cache is created in init_frame_faces.
18802 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
18804 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
18806 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
18808 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
18809 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
18810 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
18812 Improve buffer-overflow checking (Bug#8873).
18813 * fileio.c (Finsert_file_contents):
18814 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
18815 Remove the old (too-loose) buffer overflow checks.
18816 They weren't needed, since make_gap checks for buffer overflow.
18817 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
18818 The old code merely checked for Emacs fixnum overflow, and relied
18819 on undefined (wraparound) behavior. The new code avoids undefined
18820 behavior, and also checks for ptrdiff_t and/or size_t overflow.
18822 * editfns.c (Finsert_char): Don't dump core with very negative counts.
18823 Tune. Don't use wider integers than needed. Don't use alloca.
18824 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
18826 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
18828 * insdel.c, lisp.h (buffer_overflow): New function.
18829 (insert_from_buffer_1, replace_range, replace_range_2):
18830 * insdel.c (make_gap_larger):
18831 * editfns.c (Finsert_char):
18832 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
18834 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
18836 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
18838 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
18840 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
18841 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
18843 * fileio.c: Don't assume EMACS_INT fits in off_t.
18844 (emacs_lseek): New static function.
18845 (Finsert_file_contents, Fwrite_region): Use it.
18846 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
18848 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
18850 * fns.c: Don't overflow int when computing a list length.
18851 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
18852 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
18853 truncation on 64-bit hosts. Check for QUIT every
18854 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
18855 faster and is responsive enough.
18856 (Flength): Report an error instead of overflowing an integer.
18857 (Fsafe_length): Return a float if the value is not representable
18858 as a fixnum. This shouldn't happen except in contrived situations.
18859 (Fnthcdr, Fsort): Don't assume list length fits in int.
18860 (Fcopy_sequence): Don't assume vector length fits in int.
18862 * alloc.c: Check that resized vectors' lengths fit in fixnums.
18863 (header_size, word_size): New constants.
18864 (allocate_vectorlike): Don't check size overflow here.
18865 (allocate_vector): Check it here instead, since this is the only
18866 caller of allocate_vectorlike that could cause overflow.
18867 Check that the new vector's length is representable as a fixnum.
18869 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
18870 The previous code was bogus. For example, next_almost_prime (32)
18871 returned 39, which is undesirable as it is a multiple of 3; and
18872 next_almost_prime (24) returned 25, which is a multiple of 5 so
18873 why was the code bothering to check for multiples of 7?
18875 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
18877 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
18879 Variadic C functions now count arguments with ptrdiff_t.
18880 This partly undoes my 2011-03-30 change, which replaced int with size_t.
18881 Back then I didn't know that the Emacs coding style prefers signed int.
18882 Also, in the meantime I found a few more instances where arguments
18883 were being counted with int, which may truncate counts on 64-bit
18884 machines, or EMACS_INT, which may be unnecessarily wide.
18885 * lisp.h (struct Lisp_Subr.function.aMANY)
18886 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
18887 Arg counts are now ptrdiff_t, not size_t.
18888 All variadic functions and their callers changed accordingly.
18889 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
18890 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
18891 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
18892 * callint.c (Fcall_interactively): Check arg count for overflow,
18893 to avoid potential buffer overrun. Use signed char, not 'int',
18894 for 'varies' array, so that we needn't bother to check its size
18895 calculation for overflow.
18896 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
18897 * eval.c (apply_lambda):
18898 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
18899 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
18900 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
18902 * callint.c (Fcall_interactively): Don't use index var as event count.
18904 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
18905 * mem-limits.h (SIZE): Remove; no longer used.
18907 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
18909 Remove unnecessary casts.
18910 * xterm.c (x_term_init):
18911 * xfns.c (x_set_border_pixel):
18912 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
18913 These aren't needed now that we assume ANSI C.
18915 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
18916 It's more likely to cause problems (due to unsigned overflow)
18919 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
18921 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
18923 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
18925 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
18927 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
18929 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
18931 GLYPH_CODE_FACE returns EMACS_INT, not int.
18932 * dispextern.h (merge_faces):
18933 * xfaces.c (merge_faces):
18934 * xdisp.c (get_next_display_element, next_element_from_display_vector):
18935 Don't assume EMACS_INT fits in int.
18937 * character.h (CHAR_VALID_P): Remove unused parameter.
18938 * fontset.c, lisp.h, xdisp.c: All uses changed.
18940 * editfns.c (Ftranslate_region_internal): Omit redundant test.
18942 * fns.c (concat): Minor tuning based on overflow analysis.
18943 This doesn't fix any bugs. Use int to hold character, instead
18944 of constantly refetching from Emacs object. Use XFASTINT, not
18945 XINT, for value known to be a character. Don't bother comparing
18946 a single byte to 0400, as it's always less.
18948 * floatfns.c (Fexpt):
18949 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
18951 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
18954 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
18956 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
18957 Without this fix, on a 64-bit host (aset S 0 4294967386) would
18958 incorrectly succeed when S was a string, because 4294967386 was
18959 truncated before it was used.
18961 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
18962 Otherwise, an out-of-range integer could cause undefined behavior
18965 * composite.c: Use int, not EMACS_INT, for characters.
18966 (fill_gstring_body, composition_compute_stop_pos): Use int, not
18967 EMACS_INT, for values that are known to be in character range.
18968 This doesn't fix any bugs but is the usual style inside Emacs and
18969 may generate better code on 32-bit machines.
18971 Make sure a 64-bit char is never passed to ENCODE_CHAR.
18972 This is for reasons similar to the recent CHAR_STRING fix.
18973 * charset.c (Fencode_char): Check that character arg is actually
18974 a character. Pass an int to ENCODE_CHAR.
18975 * charset.h (ENCODE_CHAR): Verify that the character argument is no
18976 wider than 'int', as a compile-time check to prevent future regressions
18979 * character.c (char_string): Remove unnecessary casts.
18981 Make sure a 64-bit char is never passed to CHAR_STRING.
18982 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
18983 by silently ignoring the top 32 bits, allowing some values
18984 that were far too large to be valid characters.
18985 * character.h: Include <verify.h>.
18986 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
18987 arguments are no wider than unsigned, as a compile-time check
18988 to prevent future regressions in this area.
18990 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
18991 (Fsubst_char_in_region):
18993 * xdisp.c (decode_mode_spec_coding):
18994 Adjust to CHAR_STRING's new requirement.
18995 * editfns.c (Finsert_char, Fsubst_char_in_region):
18996 * fns.c (concat): Check that character args are actually
18997 characters. Without this test, these functions did the wrong
18998 thing with wildly out-of-range values on 64-bit hosts.
19000 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
19001 These casts should not be needed on 32-bit hosts, either.
19002 * keyboard.c (read_char):
19003 * lread.c (Fload): Remove casts to unsigned.
19005 * lisp.h (UNSIGNED_CMP): New macro.
19006 This fixes comparison bugs on 64-bit hosts.
19007 (ASCII_CHAR_P): Use it.
19008 * casefiddle.c (casify_object):
19009 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
19010 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
19011 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
19012 * dispextern.h (FACE_FROM_ID):
19013 * keyboard.c (read_char): Use UNSIGNED_CMP.
19015 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
19016 not to EMACS_INT, to avoid GCC warning.
19018 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
19020 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
19021 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
19022 isn't needed on 32-bit machines.
19024 * buffer.c (Fgenerate_new_buffer_name):
19025 Use EMACS_INT for count, not int.
19026 (advance_to_char_boundary): Return EMACS_INT, not int.
19028 * data.c (Qcompiled_function): Now static.
19030 * window.c (window_body_lines): Now static.
19032 * image.c (gif_load): Rename local to avoid shadowing.
19034 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
19035 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
19036 * alloc.c (make_save_value): Integer argument is now of type
19037 ptrdiff_t, not int.
19038 (mark_object): Use ptrdiff_t, not int.
19039 * lisp.h (pD): New macro.
19040 * print.c (print_object): Use it.
19042 * alloc.c: Use EMACS_INT, not int, to count objects.
19043 (total_conses, total_markers, total_symbols, total_vector_size)
19044 (total_free_conses, total_free_markers, total_free_symbols)
19045 (total_free_floats, total_floats, total_free_intervals)
19046 (total_intervals, total_strings, total_free_strings):
19047 Now EMACS_INT, not int. All uses changed.
19048 (Fgarbage_collect): Compute overall total using a double, so that
19049 integer overflow is less likely to be a problem. Check for overflow
19050 when converting back to an integer.
19051 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
19052 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
19053 These were 'int' variables that could overflow on 64-bit hosts;
19054 they were never used, so remove them instead of repairing them.
19055 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
19056 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
19057 Previously, this ceilinged at INT_MAX, but that doesn't work on
19059 (allocate_pseudovector): Don't use EMACS_INT when int would do.
19061 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
19062 (allocate_vectorlike): Check for ptrdiff_t overflow.
19063 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
19064 when a (possibly-narrower) signed value would do just as well.
19065 We prefer using signed arithmetic, to avoid comparison confusion.
19067 * alloc.c: Catch some string size overflows that we were missing.
19068 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
19069 for convenience in STRING_BYTES_MAX.
19070 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
19071 The definition here is exact; the one in lisp.h was approximate.
19072 (allocate_string_data): Check for string overflow. This catches
19073 some instances we weren't catching before. Also, it catches
19074 size_t overflow on (unusual) hosts where SIZE_MAX <= min
19075 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
19076 and ptrdiff_t and EMACS_INT are both 64 bits.
19078 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
19079 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
19080 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
19082 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
19084 * alloc.c (Fmake_string): Check for out-of-range init.
19086 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
19088 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.

19530 (Fsingle_key_description, preferred_sequence_p): XUINT -> XINT,
19531 since it makes no difference and we prefer signed.
19532 * keyboard.c (record_char): Use XUINT when all the neighbors do.
19533 (access_keymap): NATNUMP -> INTEGERP, since the integer must be
19536 2011-06-06 Stefan Monnier <monnier@iro.umontreal.ca>

19576 (Fwindow_minibuffer_p): Move up in code and simplify.
19577 (Fset_frame_selected_window): Move here from frame.c.
19579 (Fselected_window, select_window, Fselect_window): Move up in
19580 code. Minor doc-string fixes.
19582 2011-06-06 Paul Eggert <eggert@cs.ucla.edu>
19584 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
19585 Do not assume that spare memory exists; that assumption is valid
19586 only if SYSTEM_MALLOC.
19587 (LARGE_REQUEST): New macro, so that the issue of large requests
19588 is separated from the issue of spare memory.
19590 2011-06-05 Andreas Schwab <schwab@linux-m68k.org>
19592 * editfns.c (Fformat): Correctly handle zero flag with hexadecimal

19618 New error handlers.
19619 (x_clipboard_manager_save_frame, x_clipboard_manager_save_all):
19620 Obey Vx_select_enable_clipboard_manager. Catch errors in
19621 x_clipboard_manager_save (Bug#8779).
19622 (Vx_select_enable_clipboard_manager): New variable.
19623 (x_get_foreign_selection): Reduce scope of x_catch_errors (Bug#8790).
19625 2011-06-04 Dan Nicolaescu <dann@ics.uci.edu>
19627 * emacs.c (main): Warn when starting a GTK emacs in daemon mode.
19629 2011-06-04 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
19631 * fringe.c (update_window_fringes): Don't update overlay arrow bitmap

19638 2011-06-03 Eli Zaretskii <eliz@gnu.org>
19640 Support bidi reordering of text covered by display properties.
19642 * bidi.c (bidi_copy_it): Use offsetof instead of emulating it.
19643 (bidi_fetch_char, bidi_fetch_char_advance): New functions.
19644 (bidi_cache_search, bidi_cache_iterator_state)
19645 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
19646 (bidi_level_of_next_char, bidi_move_to_visually_next):
19647 Support character positions inside a run of characters covered by a
19649 (bidi_paragraph_init, bidi_resolve_explicit_1)
19650 (bidi_level_of_next_char): Call bidi_fetch_char and
19651 bidi_fetch_char_advance instead of FETCH_CHAR and

19654 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
19656 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
19657 instead of using explicit *_CHAR codes.
19658 (bidi_resolve_explicit, bidi_resolve_weak):
19659 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
19660 bidirectional text is supported only in multibyte buffers.
19661 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
19662 it to initialize the frame_window_p member of struct bidi_it.

19666 bidi_it->nchars is non-positive.
19667 (bidi_level_of_next_char): Don't try to lookup the cache for the
19668 next/previous character if nothing is cached there yet, or if we
19669 were just reseat()'ed to a new position.
19671 * xdisp.c (set_cursor_from_row): Set start and stop points
19672 according to the row's direction when priming the loop that looks
19673 for the glyph on which to display cursor.
19674 (single_display_spec_intangible_p): Function deleted.
19675 (display_prop_intangible_p): Reimplement to call
19676 handle_display_spec instead of single_display_spec_intangible_p.
19677 Accept 3 additional arguments needed by handle_display_spec.
19678 This fixes incorrect cursor motion across display property with complex
19679 values: lists, `(when COND...)' forms, etc.
19680 (single_display_spec_string_p): Support property values that are
19681 lists with the argument STRING its top-level element.
19682 (display_prop_string_p): Fix the condition for processing a
19683 property that is a list to be consistent with handle_display_spec.

19685 last portion of handle_display_prop.
19686 (compute_display_string_pos): Accept additional argument
19687 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
19688 value of a `display' property is a "replacing spec".
19689 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
19690 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
19691 the display property, but just return a value indicating whether
19692 the display property will replace the characters it covers.
19693 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
19694 frame_window_p members of struct bidi_it.
19695 (compute_display_string_pos, compute_display_string_end):
19697 (push_it): Accept second argument POSITION, where pop_it should
19698 jump to continue iteration.
19699 (reseat_1): Initialize bidi_it.disp_pos.
19701 * keyboard.c (adjust_point_for_property): Adjust the call to
19702 display_prop_intangible_p to its new signature.
19704 * dispextern.h (struct bidi_it): New member frame_window_p.
19705 (bidi_init_it): Update prototypes.
19706 (display_prop_intangible_p): Update prototype.
19707 (compute_display_string_pos, compute_display_string_end):

19712 2011-06-02 Paul Eggert <eggert@cs.ucla.edu>
19714 Malloc failure behavior now depends on size of allocation.
19715 * alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
19716 * lisp.h: Change signatures accordingly.
19717 * alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
19718 All callers changed. (Bug#8762)
19720 * gnutls.c: Use Emacs's memory allocators.
19721 Without this change, the gnutls library would invoke malloc etc.
19722 directly, which causes problems on non-SYNC_INPUT hosts, and which
19723 runs afoul of improving memory_full behavior. (Bug#8761)
19724 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
19725 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
19726 xfree instead of the default malloc, realloc, free.
19727 (Fgnutls_boot): No need to check for memory allocation failure,
19728 since xmalloc does that for us.
19730 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
19731 * category.c (hash_get_category_set):
19732 * ccl.c (ccl_driver):
19733 * charset.c (Fdefine_charset_internal):

19744 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector)
19745 (Fsxhash, Fgethash, Fputhash, Fmaphash):
19746 * image.c (make_image, search_image_cache, lookup_image)
19747 (xpm_put_color_table_h):
19748 * lisp.h (struct Lisp_Hash_Table):
19749 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
19750 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
19751 for hashes and hash indexes, instead of 'unsigned' and 'int'.
19752 * alloc.c (allocate_vectorlike):
19753 Check for overflow in vector size calculations.
19754 * ccl.c (ccl_driver):
19755 Check for overflow when converting EMACS_INT to int.
19756 * fns.c, image.c: Remove unnecessary static decls that would otherwise
19757 need to be updated by these changes.
19758 * fns.c (make_hash_table, maybe_resize_hash_table):
19759 Check for integer overflow with large hash tables.
19760 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
19761 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
19762 (SXHASH_REDUCE): New macro.
19763 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
19764 Use it instead of discarding useful hash info with large hash values.
19765 (sxhash_float): New function.
19766 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
19767 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
19768 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
19769 Rewrite to use FIXNUM_BITS, as this simplifies things.
19770 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
19771 Adjust signatures to match updated version of code.
19772 (consing_since_gc): Now EMACS_INT, since a single hash table can
19773 use more than INT_MAX bytes.
19775 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
19777 Make it possible to build with GCC-4.6+ -O2 -flto.
19779 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
19781 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
19783 * minibuf.c (get_minibuffer, read_minibuf_unwind):
19784 Call minibuffer-inactive-mode.
19786 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
19788 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
19789 Update dependencies.
19791 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19793 * data.c (init_data): Remove code for UTS, this system is not
19796 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19798 Don't force ./temacs to start in terminal mode.
19800 * frame.c (make_initial_frame): Initialize faces in all cases, not
19801 only when CANNOT_DUMP is defined.
19802 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
19804 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19806 * dispnew.c (add_window_display_history): Use const for the string
19807 pointer. Remove declaration, not needed.
19809 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
19811 Use 'inline', not 'INLINE'.
19812 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
19813 * alloc.c, fontset.c (INLINE): Remove.
19814 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
19815 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
19816 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
19817 * gmalloc.c (register_heapinfo): Use inline unconditionally.
19818 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
19820 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
19822 Make it possible to run ./temacs.
19824 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
19825 syms_of_callproc does the same thing. Remove test for
19826 "initialized", do it in the caller.
19827 * emacs.c (main): Avoid calling set_initial_environment when dumping.
19829 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
19831 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
19832 (read_minibuf): Use get_minibuffer.
19833 (syms_of_minibuf): Use DEFSYM.
19834 (Qmetadata): New var.
19835 * data.c (Qbuffer): Don't make it static.
19836 (syms_of_data): Use DEFSYM.
19838 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
19840 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
19841 (CCL_CODE_MIN): New macro.
19843 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
19845 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
19847 * eval.c (Qdebug): Now static.
19848 * lisp.h (Qdebug): Remove decl. This reverts a part of the
19849 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
19850 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
19852 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
19854 * image.c: Various fixes to ImageMagick code comments.
19855 (Fimagemagick_types): Doc fix.
19857 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
19859 Minor fixes prompted by GCC 4.6.0 warnings.
19861 * xselect.c (converted_selections, conversion_fail_tag): Now static.
19863 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
19864 (x_clipboard_manager_save_all): Move extern decl to ...
19865 * xterm.h: ... here, so that it can be checked for consistency.
19867 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
19869 * xselect.c (x_clipboard_manager_save_frame)
19870 (x_clipboard_manager_save_all): New functions.
19871 (Fx_clipboard_manager_save): Lisp function deleted.
19873 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
19874 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
19876 * xterm.h: Update prototype.
19878 2011-05-28 William Xu <william.xwl@gmail.com>
19880 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
19881 exiting (Bug#8239).
19883 2011-05-28 Jim Meyering <meyering@redhat.com>
19885 Avoid a sign-extension bug in crypto_hash_function.
19886 * fns.c (to_uchar): Define.
19887 (crypto_hash_function): Use it to convert some newly-signed
19888 variables to unsigned, to avoid sign-extension bugs. For example,
19889 without this change, (md5 "truc") would evaluate to
19890 45723a2aff78ff4fff7fff1114760e62 rather than the expected
19891 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
19892 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
19894 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
19896 Integer overflow fixes.
19898 * dbusbind.c: Serial number integer overflow fixes.
19899 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
19900 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
19901 to hold a serial number that is too large for a fixnum.
19902 (Fdbus_method_return_internal, Fdbus_method_error_internal):
19903 Check for serial numbers out of range. Decode any serial number
19904 that was so large that it became a float. (Bug#8722)
19906 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
19907 (Fdbus_call_method, Fdbus_call_method_asynchronously):
19908 Use XFASTINT rather than XUINT when numbers are nonnegative.
19909 (xd_append_arg, Fdbus_method_return_internal):
19910 (Fdbus_method_error_internal): Likewise. Also, for unsigned
19911 arguments, check that Lisp number is nonnegative, rather than
19912 silently wrapping negative numbers around. (Bug#8722)
19913 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
19916 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
19918 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
19920 ccl: Add integer overflow checks.
19921 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
19922 (IN_INT_RANGE): New macros.
19923 (ccl_driver): Use them to check for integer overflow when
19924 decoding a CCL program. Many of the new checks are whether XINT (x)
19925 fits in int; it doesn't always, on 64-bit hosts. The new version
19926 doesn't catch all possible integer overflows, but it's an
19927 improvement. (Bug#8719)
19929 * alloc.c (make_event_array): Use XINT, not XUINT.
19930 There's no need for unsigned here.
19932 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
19933 This follows up to the 2011-05-06 change that substituted uintptr_t
19934 for EMACS_INT. This case wasn't caught back then.
19936 Rework Fformat to avoid integer overflow issues.
19937 * editfns.c: Include <float.h> unconditionally, as it's everywhere
19938 now (part of C89). Include <verify.h>.
19939 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
19940 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
19941 (Fformat): Avoid the prepass trying to compute sizes; it was only
19942 approximate and thus did not catch overflow reliably. Instead, walk
19943 through the format just once, formatting and computing sizes as we go,
19944 checking for integer overflow at every step, and allocating a larger
19945 buffer as needed. Keep track separately whether the format is
19946 multibyte. Keep only the most-recently calculated precision, rather
19947 than them all. Record whether each argument has been converted to
19948 string. Use EMACS_INT, not int, for byte and char and arg counts.
19949 Support field widths and precisions larger than INT_MAX. Avoid
19950 sprintf's undefined behavior with conversion specifications such as %#d
19951 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
19952 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
19953 formatting out-of-range floating point numbers with int
19954 formats. (Bug#8668)
19956 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
19958 * data.c: Avoid integer truncation in expressions involving floats.
19959 * data.c: Include <intprops.h>.
19960 (arith_driver): When there's an integer overflow in an expression
19961 involving floating point, convert the integers to floating point
19962 so that the resulting value does not suffer from catastrophic
19963 integer truncation. For example, on a 64-bit host (* 4
19964 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
19965 Do not rely on undefined behavior after integer overflow.
19967 merge count_size_as_multibyte, parse_str_to_multibyte
19968 * character.c, character.h (count_size_as_multibyte):
19969 Rename from parse_str_to_multibyte; all uses changed.
19970 Check for integer overflow.
19971 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
19972 since it's now a duplicate of the other. This is more of
19973 a character than a buffer op, so better that it's in character.c.
19974 * fns.c, print.c: Adjust to above changes.
19976 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
19978 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
19980 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
19982 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
19983 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
19984 (x_clipboard_manager_save): Now static.
19985 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
19987 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
19988 (crypto_hash_function): Now static.
19989 Fix pointer signedness problems. Avoid unnecessary initializations.
19991 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
19993 * termhooks.h (Vselection_alist): Make it terminal-local.
19995 * terminal.c (create_terminal): Initialize it.
19997 * xselect.c: Support for clipboard managers.
19998 (Vselection_alist): Move to termhooks.h as terminal-local var.
19999 (LOCAL_SELECTION): New macro.
20000 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
20001 (symbol_to_x_atom): Remove gratuitous arg.
20002 (x_handle_selection_request, lisp_data_to_selection_data)
20003 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
20004 (x_own_selection, x_get_local_selection, x_convert_selection):
20005 New arg, specifying work frame. Use terminal-local Vselection_alist.
20006 (some_frame_on_display): Delete unused function.
20007 (Fx_own_selection_internal, Fx_get_selection_internal)
20008 (Fx_disown_selection_internal, Fx_selection_owner_p)
20009 (Fx_selection_exists_p): New optional frame arg.
20010 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
20011 (x_handle_selection_clear): Don't treat other terminals with the
20012 same keyboard specially. Use the terminal-local Vselection_alist.
20013 (x_clear_frame_selections): Use Frun_hook_with_args.
20015 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
20017 * xterm.h: Add support for those atoms.
20019 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
20021 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
20022 (converted_selections, conversion_fail_tag): New global variables.
20023 (x_selection_request_lisp_error): Free the above.
20024 (x_get_local_selection): Remove unnecessary code.
20025 (x_reply_selection_request): Args changed; handle arbitrary array
20026 of converted selections stored in converted_selections.
20027 Separate the XChangeProperty and SelectionNotify steps.
20028 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
20029 (x_convert_selection): New function.
20030 (x_handle_selection_event): Simplify.
20031 (x_get_foreign_selection): Don't ignore incoming requests while
20032 waiting for an answer; this will fail when we implement
20033 SAVE_TARGETS, and seems unnecessary anyway.
20034 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
20035 (Vx_sent_selection_functions): Doc fix.
20037 2011-05-26 Leo Liu <sdl.web@gmail.com>
20039 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
20041 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
20043 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
20045 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
20046 for fringe update if it has periodic bitmap.
20047 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
20048 and fringe_bitmap_periodic_p.
20050 * fringe.c (get_fringe_bitmap_data): New function.
20051 (draw_fringe_bitmap_1, update_window_fringes): Use it.
20052 (update_window_fringes): Record periodicity of fringe bitmap in glyph
20053 row. Mark glyph row for fringe update if periodicity changed.
20055 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
20056 for fringe update unless it has periodic bitmap.
20058 2011-05-25 Kenichi Handa <handa@m17n.org>
20060 * xdisp.c (get_next_display_element): Set correct it->face_id for
20061 a static composition.
20063 2011-05-24 Leo Liu <sdl.web@gmail.com>
20066 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
20068 * fns.c (crypto_hash_function, Fsha1): New function.
20069 (Fmd5): Use crypto_hash_function.
20070 (syms_of_fns): Add Ssha1.
20072 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
20074 * gnutls.c: Remove unused macros.
20075 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
20076 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
20077 Remove macros that are defined and never used.
20078 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
20080 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
20082 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
20083 (Fx_get_selection_internal): Minor cleanup.
20084 (Fx_own_selection_internal): Rename arguments for consistency with
20087 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
20089 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
20091 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
20093 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
20095 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
20097 * dispnew.c (scrolling_window): Don't exclude the case that the
20098 last enabled row in the desired matrix touches the bottom boundary.
20100 2011-05-21 Glenn Morris <rgm@gnu.org>
20102 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
20103 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
20104 and add some more files.
20106 2011-05-20 Eli Zaretskii <eliz@gnu.org>
20108 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
20109 report_file_error introduced by the change from 2011-05-07.
20111 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
20113 * systime.h (Time): Define only if emacs is defined.
20114 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
20115 where the include path doesn't have X11/X.h by default. See
20116 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
20118 2011-05-20 Kenichi Handa <handa@m17n.org>
20120 * composite.c (find_automatic_composition): Fix previous change.
20122 2011-05-20 Glenn Morris <rgm@gnu.org>
20124 * lisp.mk: New file, split from Makefile.in.
20125 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
20126 (shortlisp): Remove.
20127 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
20129 2011-05-19 Glenn Morris <rgm@gnu.org>
20131 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
20132 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
20133 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
20134 (lisp): Set the order to that of loadup.el.
20135 (shortlisp): Make it a copy of $lisp.
20136 (SOME_MACHINE_LISP): Remove.
20137 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
20138 Use just $shortlisp, not $SOME_MACHINE_LISP too.
20140 2011-05-18 Kenichi Handa <handa@m17n.org>
20142 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
20143 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
20144 (find_automatic_composition): Mostly rewrite for efficiency.
20146 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
20148 * makefile.w32-in: Update dependencies.
20150 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
20152 * menu.c: Include limits.h (fixes the MS-Windows build broken by
20153 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
20155 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
20157 Fix some integer overflow issues, such as string length overflow.
20159 * insdel.c (count_size_as_multibyte): Check for string overflow.
20161 * character.c (lisp_string_width): Check for string overflow.
20162 Use EMACS_INT, not int, for string indexes and lengths; in
20163 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
20164 the resulting string length overflows an EMACS_INT; instead,
20165 report a string overflow if no precision given. When checking for
20166 precision exhaustion, use a check that cannot possibly have
20167 integer overflow. (Bug#8675)
20168 * character.h (lisp_string_width): Adjust to new signature.
20170 * alloc.c (string_overflow): New function.
20171 (Fmake_string): Use it. This doesn't change behavior, but saves
20172 a few bytes and will simplify future changes.
20173 * character.c (string_escape_byte8): Likewise.
20174 * lisp.h (string_overflow): New decl.
20176 Fixups, following up to the user-interface timestamp change.
20177 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
20178 for UI timestamps, instead of unsigned long.
20179 * msdos.c (mouse_get_pos): Likewise.
20180 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
20181 * w32gui.h (Time): Define by including "systime.h" rather than by
20182 declaring it ourselves. (Bug#8664)
20184 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
20185 * image.c (clear_image_cache): Likewise.
20187 * term.c (term_mouse_position): Don't assume time_t wraparound.
20189 Be more systematic about user-interface timestamps.
20190 Before, the code sometimes used 'Time', sometimes 'unsigned long',
20191 and sometimes 'EMACS_UINT', to represent these timestamps.
20192 This change causes it to use 'Time' uniformly, as that's what X uses.
20193 This makes the code easier to follow, and makes it easier to catch
20194 integer overflow bugs such as Bug#8664.
20195 * frame.c (Fmouse_position, Fmouse_pixel_position):
20196 Use Time, not unsigned long, for user-interface timestamps.
20197 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
20198 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
20199 * keyboard.h (last_event_timestamp): Likewise.
20200 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
20201 * menu.h (xmenu_show): Likewise.
20202 * term.c (term_mouse_position): Likewise.
20203 * termhooks.h (struct input_event.timestamp): Likewise.
20204 (struct terminal.mouse_position_hook): Likewise.
20205 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
20206 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
20207 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
20208 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
20209 what it was before.
20210 * menu.h, termhooks.h: Include "systime.h", for Time.
20212 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
20213 Don't assume that the difference between two unsigned long values
20214 can fit into an integer. At this point, we know button_down_time
20215 <= event->timestamp, so the difference must be nonnegative, so
20216 there's no need to cast the result if double-click-time is
20217 nonnegative, as it should be; check that it's nonnegative, just in
20218 case. This bug is triggered when events are more than 2**31 ms
20219 apart (about 25 days). (Bug#8664)
20221 * xselect.c (last_event_timestamp): Remove duplicate decl.
20222 (x_own_selection): Remove needless cast to unsigned long.
20224 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
20225 that always fit in int. Use a sentinel instead of a counter, to
20226 avoid a temp and to allay GCC's concerns about possible int overflow.
20227 * frame.h (struct frame): Use int for menu_bar_items_used
20228 instead of EMACS_INT, since it always fits in int.
20230 * menu.c (grow_menu_items): Check for int overflow.
20232 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
20234 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
20235 Before, the code was not consistent. These values cannot exceed
20236 2**31 - 1 so there's no need to make them unsigned.
20237 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
20238 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
20239 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
20241 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
20243 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
20244 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
20245 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
20246 presumably because the widths might not match.
20248 * window.c (size_window): Avoid needless test at loop start.
20250 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
20252 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
20254 2011-05-12 Drew Adams <drew.adams@oracle.com>
20256 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
20258 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
20260 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
20261 `width' to `bar_area_x' and `bar_area_width', respectively.
20262 (x_scroll_run): Take account of fringe background extension.
20264 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
20265 Rename local vars `left' and `width' to `bar_area_x' and
20266 `bar_area_width', respectively.
20267 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
20268 background extension.
20270 2011-05-10 Jim Meyering <meyering@redhat.com>
20272 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
20274 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
20276 * image.c (Finit_image_library): Return t for built-in image types,
20277 like pbm and xbm. (Bug#8640)
20279 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
20281 * w32menu.c (set_frame_menubar): Fix submenu allocation.
20283 2011-05-07 Eli Zaretskii <eliz@gnu.org>
20285 * w32console.c (Fset_screen_color): Doc fix.
20286 (Fget_screen_color): New function.
20287 (syms_of_ntterm): Defsubr it.
20289 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
20290 unlink the temporary file if Fcall_process didn't create it in the
20292 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
20293 child process will be redirected to a file specified with `:file'.
20294 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
20295 cue to call_process_cleanup not to close that handle.
20297 2011-05-07 Ben Key <bkey76@gmail.com>
20299 * makefile.w32-in: The bootstrap-temacs rule now makes use of
20300 one of two shell specific rules, either bootstrap-temacs-CMD or
20301 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
20302 to the previous implementation of the bootstrap-temacs rule.
20303 The bootstrap-temacs-CMD rule is similar to the previous
20304 implementation of the bootstrap-temacs rule except that it
20305 makes use of the ESC_CFLAGS variable instead of the CFLAGS
20308 These changes, along with some changes to nt/configure.bat,
20309 nt/gmake.defs, and nt/nmake.defs, are required to extend my
20310 earlier fix to add support for --cflags and --ldflags options
20311 that include quotes so that it works whether make uses cmd or
20314 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
20316 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
20317 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
20319 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
20320 a string. Handle both cases.
20321 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
20322 (Fdbus_register_method): Use Qinvalid_function.
20324 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
20326 * makefile.w32-in: Update dependencies.
20327 (LISP_H): Add inttypes.h and stdin.h.
20328 (PROCESS_H): Add unistd.h.
20330 2011-05-06 Eli Zaretskii <eliz@gnu.org>
20332 * lread.c: Include limits.h (fixes the MS-Windows build broken by
20333 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
20335 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
20337 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
20339 * term.c (vfatal): Remove stray call to va_end.
20340 It's not needed and the C Standard doesn't allow it here anyway.
20342 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
20343 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
20345 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
20348 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
20350 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
20352 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
20354 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
20356 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
20358 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
20359 * charset.c (Fdefine_charset_internal): Don't initialize
20360 charset.code_space[15]. The value was garbage, on hosts with
20361 32-bit int (Bug#8600).
20363 * lread.c (read_integer): Be more consistent with string-to-number.
20364 Use string_to_number to do the actual conversion; this avoids
20365 rounding errors and fixes some other screwups. Without this fix,
20366 for example, #x1fffffffffffffff was misread as -2305843009213693952.
20367 (digit_to_number): Move earlier, for benefit of read_integer.
20368 Return -1 if the digit is out of range for the base, -2 if it is
20369 not a digit in any supported base. (Bug#8602)
20371 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
20373 * dispnew.c (scrolling_window): Return 1 if we scrolled,
20374 to match comment at start of function. This also removes a
20375 GCC warning about overflow in a 32+64-bit port.
20377 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
20379 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
20380 Reported by Stefan Monnier in
20381 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
20382 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
20383 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
20385 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
20386 (EMACS_UINTPTR): Likewise, with uintptr_t.
20388 * lisp.h: Prefer 64-bit EMACS_INT if available.
20389 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
20390 on 32-bit hosts that have 64-bit int, so that they can access
20392 However, temporarily disable this change unless the temporary
20393 symbol WIDE_EMACS_INT is defined.
20395 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
20397 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
20398 This removes an assumption that EMACS_INT and long are the same
20399 width as pointers. The assumption is true for Emacs porting targets
20400 now, but we want to make other targets possible.
20401 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
20402 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
20403 In the rest of the code, change types of integers that hold casted
20404 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
20405 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
20406 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
20407 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
20408 No need to cast type when ORing.
20409 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
20410 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
20411 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
20412 assume EMACS_INT is the same width as char *.
20413 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
20414 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
20415 Remove no-longer-needed casts.
20416 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
20417 (xg_tool_bar_help_callback, xg_make_tool_item):
20418 Use EMACS_INTPTR to hold an integer
20419 that will be cast to void *; this can avoid a GCC warning
20420 if EMACS_INT is not the same width as void *.
20421 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
20422 * xdisp.c (display_echo_area_1, resize_mini_window_1):
20423 (current_message_1, set_message_1):
20424 Use a local to convert to proper width without a cast.
20425 * xmenu.c (dialog_selection_callback): Likewise.
20427 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
20428 Also, don't assume VALBITS / RAND_BITS is less than 5,
20429 and don't rely on undefined behavior when shifting a 1 left into
20431 * lisp.h (get_random): Change signature to match.
20433 * lread.c (hash_string): Use size_t, not int, for hash computation.
20434 Normally we prefer signed values; but hashing is special, because
20435 it's better to use unsigned division on hash table sizes so that
20436 the remainder is nonnegative. Also, size_t is the natural width
20437 for hashing into memory. The previous code used 'int', which doesn't
20438 retain enough info to hash well into very large tables.
20439 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
20441 * dbusbind.c: Don't possibly lose pointer info when converting.
20442 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
20443 Use XPNTR rather than XHASH, so that the high-order bits of
20444 the pointer aren't lost when converting through void *.
20446 * eval.c (Fautoload): Don't double-shift a pointer.
20448 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
20450 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
20452 * gnutls.c (DEF_GNUTLS_FN):
20453 * image.c (DEF_IMGLIB_FN): Make function pointers static.
20455 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
20457 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
20460 2011-05-05 Eli Zaretskii <eliz@gnu.org>
20462 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
20463 New version that can reserve upto 2GB of heap space.
20465 2011-05-05 Chong Yidong <cyd@stupidchicken.com>

20471 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
20472 `gnutls_certificate_set_x509_key_file'.
20474 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
20476 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
20477 Update dependencies.
20479 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
20481 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
20482 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
20483 Remove unused parameter `fildes'.
20484 * process.c (read_process_output, send_process): Don't pass it.
20486 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
20488 Fix previous change: the library cache is defined in w32.c.
20489 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
20490 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
20492 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
20494 Implement dynamic loading of GnuTLS on Windows.
20496 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
20497 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
20498 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):

20509 (emacs_gnutls_write, emacs_gnutls_read)
20510 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
20511 (Fgnutls_available_p): New function.
20512 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.

20522 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
20524 * w32.c (QCloaded_from, Vlibrary_cache): Define.
20525 (w32_delayed_load): Move from image.c. When loading a library, record
20526 its filename in the :loaded-from property of the library id.
20527 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
20528 Initialize and staticpro them.
20529 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
20531 * process.c: Include lisp.h before w32.h, not after.
20532 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
20533 instead of gnutls_record_check_pending.
20535 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
20537 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
20539 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
20540 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
20543 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
20545 * xterm.c (x_set_frame_alpha): Do not set property on anything
20546 else than FRAME_X_OUTER_WINDOW (Bug#8608).
20548 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
20550 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
20552 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
20554 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
20555 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

20568 * sysdep.c (wait_for_termination_1): Make static.
20569 (wait_for_termination, interruptible_wait_for_termination):
20570 Move after wait_for_termination_1.
20572 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
20574 * sysdep.c (interruptible_wait_for_termination): New function
20575 which is like wait_for_termination, but allows keyboard
20578 * callproc.c (Fcall_process): Add (:file "file") as an option for
20580 (Fcall_process_region): Ditto.
20582 2011-04-30 Eli Zaretskii <eliz@gnu.org>
20584 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
20585 rather than `XVECTOR (FOO)->size'.
20587 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
20588 inttypes.h, as a gnulib replacement is used if it not available in
20591 2011-04-21 Eli Zaretskii <eliz@gnu.org>
20593 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
20594 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
20595 of MOST_POSITIVE_FIXNUM. (Bug#8528)
20597 * coding.c (coding_alloc_by_realloc): Error out if destination
20598 will grow beyond MOST_POSITIVE_FIXNUM.
20599 (decode_coding_emacs_mule): Abort if there isn't enough place in
20600 charbuf for the composition carryover bytes. Reserve an extra
20601 space for up to 2 characters produced in a loop.
20602 (decode_coding_iso_2022): Abort if there isn't enough place in
20603 charbuf for the composition carryover bytes.
20605 2011-04-21 Eli Zaretskii <eliz@gnu.org>
20607 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
20608 aborting when %lld or %lll format is passed.
20609 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
20610 %llo or %llx format is passed. (Bug#8545)
20612 * window.c (window_scroll_line_based): Use a marker instead of
20613 simple variables to record original value of point. (Bug#7952)
20615 * doprnt.c (doprnt): Fix the case where a multibyte sequence
20616 produced by %s or %c overflows available buffer space. (Bug#8545)
20618 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
20620 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
20621 (SIZE_MAX): Move defn after all includes, as they might #define it.
20623 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
20625 * w32.c (init_environment): Warn about defaulting HOME to C:\.
20627 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
20629 * keyboard.c (Qdelayed_warnings_hook): Define.
20630 (command_loop_1): Run `delayed-warnings-hook'
20631 if Vdelayed_warnings_list is non-nil.
20632 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
20633 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
20635 2011-04-28 Eli Zaretskii <eliz@gnu.org>
20637 * doprnt.c (doprnt): Don't return value smaller than the buffer
20638 size if the message was truncated. (Bug#8545).
20640 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
20642 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
20643 (Fx_window_property): #if-0 the whole functions, not just the bodies.
20645 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
20647 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
20649 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
20651 * makefile.w32-in: Update dependencies.
20653 2011-04-27 Eli Zaretskii <eliz@gnu.org>
20655 Improve `doprnt' and its usage. (Bug#8545)
20656 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
20657 `format_end'. Remove support for %l as a conversion specifier.
20658 Don't use xrealloc. Improve diagnostics when the %l size modifier
20659 is used. Update the commentary.
20661 * eval.c (verror): Simplify calculation of size_t.
20663 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
20666 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
20668 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
20671 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
20673 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
20674 This makes this file independent of the recent pseudovector change.
20676 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
20678 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
20680 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
20681 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
20682 Remove unused local.
20683 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
20685 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
20686 GCC 4.6.0 optimizes based on type-based alias analysis.
20687 For example, if b is of type struct buffer * and v of type struct
20688 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
20689 != &v->size, and therefore "v->size = 1; b->size = 2; return
20690 v->size;" must therefore return 1. This assumption is incorrect
20691 for Emacs, since it type-puns struct Lisp_Vector * with many other
20692 types. To fix this problem, this patch adds a new type struct
20693 vectorlike_header that documents the constraints on layout of vectors
20694 and pseudovectors, and helps optimizing compilers not get fooled
20695 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
20696 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
20697 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
20699 (XSETPVECTYPE): Rewrite in terms of new macro.
20700 (XSETPVECTYPESIZE): New macro, specifying both type and size.
20701 This is a bit clearer, and further avoids the possibility of
20702 undesirable aliasing.
20703 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
20704 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
20705 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
20706 since Lisp_Subr is a special case (no "next" field).
20707 (ASIZE): Now uses header.size rather than size.
20708 All previous uses of XVECTOR (foo)->size replaced to use this macro,
20709 to avoid the hassle of writing XVECTOR (foo)->header.size.
20710 (struct vectorlike_header): New type.
20711 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
20712 object, to help avoid aliasing.
20713 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
20714 (SUBRP): Likewise, since Lisp_Subr is a special case.
20715 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
20716 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
20717 (struct Lisp_Hash_Table): Combine first two members into a single
20718 struct vectorlike_header member. All uses of "size" and "next" members
20719 changed to be "header.size" and "header.next".
20720 * buffer.h (struct buffer): Likewise.
20721 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
20722 * frame.h (struct frame): Likewise.
20723 * process.h (struct Lisp_Process): Likewise.
20724 * termhooks.h (struct terminal): Likewise.
20725 * window.c (struct save_window_data, struct saved_window): Likewise.
20726 * window.h (struct window): Likewise.
20727 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
20728 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
20729 * buffer.c (init_buffer_once): Likewise.
20730 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
20732 * process.c (Fformat_network_address): Use local var for size,
20735 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
20737 Make the Lisp reader and string-to-float more consistent (Bug#8525)
20738 * data.c (atof): Remove decl; no longer used or needed.
20739 (digit_to_number): Move to lread.c.
20740 (Fstring_to_number): Use new string_to_number function, to be
20741 consistent with how the Lisp reader treats infinities and NaNs.
20742 Do not assume that floating-point numbers represent EMACS_INT
20743 without losing information; this is not true on most 64-bit hosts.
20744 Avoid double-rounding errors, by insisting on integers when
20745 parsing non-base-10 numbers, as the documentation specifies.
20746 * lisp.h (string_to_number): New decl, replacing ...
20747 (isfloat_string): Remove.
20748 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
20749 (read1): Do not accept +. and -. as integers; this
20750 appears to have been a coding error. Similarly, do not accept
20751 strings like +-1e0 as floating point numbers. Do not report
20752 overflow for integer overflows unless the base is not 10 which
20753 means we have no simple and reliable way to continue.
20754 Break out the floating-point parsing into a new
20755 function string_to_number, so that Fstring_to_number parses
20756 floating point numbers consistently with the Lisp reader.
20757 (digit_to_number): Move here from data.c. Make it static inline.
20758 (E_CHAR, EXP_INT): Remove, replacing with ...
20759 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
20760 (string_to_number): New function, replacing isfloat_string.
20761 This function checks for valid syntax and produces the resulting
20762 Lisp float number too. Rework it so that string-to-number
20763 no longer mishandles examples like "1.0e+". Use strtoumax,
20764 so that overflow for non-base-10 numbers is reported only when
20765 there's no portable and simple way to convert to floating point.
20767 * textprop.c (set_text_properties_1): Rewrite for clarity,
20768 and to avoid GCC warning about integer overflow.
20770 * intervals.h (struct interval): Use EMACS_INT for members
20771 where EMACS_UINT might cause problems. See
20772 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
20773 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
20774 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
20776 (offset_intervals): Tell GCC not to worry about length overflow
20777 when negating a negative length.
20779 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
20780 (overrun_check_free): Likewise.
20782 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
20783 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
20786 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
20787 (gnutls_make_error): Rename local to avoid shadowing.
20788 (gnutls_emacs_global_deinit): ifdef out; not used.
20789 (Fgnutls_boot): Use const for pointer to readonly storage.
20790 Comment out unused local. Fix pointer signedness problems.
20792 * lread.c (openp): Don't stuff size_t into an 'int'.
20793 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
20794 about possible signed overflow.
20796 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
20797 (GDK_KEY_g): Don't define if already defined.
20798 (xg_prepare_tooltip): Avoid pointer signedness problem.
20799 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
20801 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
20802 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
20804 * xfns.c (Fx_window_property): Simplify a bit,
20805 to make a bit faster and to avoid GCC 4.6.0 warning.
20806 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
20808 * fns.c (internal_equal): Don't assume size_t fits in int.
20810 * alloc.c (compact_small_strings): Tighten assertion a little.
20812 Replace pEd with more-general pI, and fix some printf arg casts.
20813 * lisp.h (pI): New macro, generalizing old pEd macro to other
20814 conversion specifiers. For example, use "...%"pI"d..." rather
20815 than "...%"pEd"...".
20816 (pEd): Remove. All uses replaced with similar uses of pI.
20817 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
20818 * alloc.c (check_pure_size): Don't overflow by converting size to int.
20819 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
20820 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
20821 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
20822 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
20823 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
20825 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
20826 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
20827 * print.c (safe_debug_print, print_object): Likewise.
20828 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
20830 Use pI instead of if-then-else-abort. Use %p to avoid casts,
20831 avoiding the 0 flag, which is not portable.

20833 * region-cache.c (pp_cache): Likewise.
20834 * xdisp.c (decode_mode_spec): Likewise.

20839 (x_get_window_property): Don't truncate byte count to an 'int'
20842 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
20843 here, since it parses constructs like leading '-' and spaces,
20844 which are not wanted; and it overflows with large numbers.
20845 Instead, simply match F[0-9]+, which is what is wanted anyway.
20847 * alloc.c: Remove unportable assumptions about struct layout.
20848 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
20849 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
20850 (allocate_vectorlike, make_pure_vector): Use the new macros,
20851 plus offsetof, to remove unportable assumptions about struct layout.
20852 These assumptions hold on all porting targets that I know of, but
20853 they are not guaranteed, they're easy to remove, and removing them
20854 makes further changes easier.
20856 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
20857 This doesn't fix a bug but makes the code clearer.
20858 (string_overrun_cookie): Now const. Use initializers that
20859 don't formally overflow signed char, to avoid warnings.
20860 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
20861 can cause Emacs to crash when string overrun checking is enabled.
20862 (allocate_buffer): Don't assume sizeof (struct buffer) is a
20863 multiple of sizeof (EMACS_INT); it need not be, if
20864 alignof(EMACS_INT) < sizeof (EMACS_INT).
20865 (check_sblock, check_string_bytes, check_string_free_list): Protoize.

20899 Improve doprnt and its use in verror. (Bug#8545)
20900 * doprnt.c (doprnt): Document the set of format control sequences
20901 supported by the function. Use SAFE_ALLOCA instead of always
20904 * eval.c (verror): Don't limit the buffer size at size_max-1, that
20905 is one byte too soon. Don't use xrealloc; instead xfree and

20917 docstring. Start callback support.
20918 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
20919 unless a fatal error occurred. Call gnutls_alert_send_appropriate

21023 codepoint of an invalid character, to avoid displaying a bogus
21026 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
21027 `error', not SYMBOL_NAME itself.
21029 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for

21032 * charset.c (check_iso_charset_parameter): Fix incorrect argument
21033 to `error' in error message about FINAL_CHAR argument. Make sure
21034 FINAL_CHAR is a character, and use %c when it is passed as
21035 argument to `error'.
21037 2011-04-23 Eli Zaretskii <eliz@gnu.org>
21039 * s/ms-w32.h (localtime): Redirect to sys_localtime.
21041 * w32.c: Include <time.h>.

21105 * dispextern.h (struct redisplay_interface): Rename param
21106 to avoid shadowing.
21107 * termhooks.h (struct terminal): Likewise.

21224 * nsfont.m: Fixed bugs in ns_get_family and
21225 ns_descriptor_to_entity that were caused by using free to
21226 deallocate memory blocks that were allocated by xmalloc (via
21227 xstrdup). This caused Emacs to crash when compiled with
21228 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
21229 --enable-checking=xmallocoverrun). xfree is now used to
21230 deallocate these memory blocks.

21244 (emacs_read, emacs_write): Remove check for negative size, as the
21245 Emacs source code has been audited now.
21246 * sysdep.c (MAX_RW_COUNT): New macro, to work around kernel bugs.
21247 (emacs_read, emacs_write): Use it.
21248 * process.c (send_process): Adjust to the new signatures of
21249 emacs_write and emacs_gnutls_write. Do not attempt to store
21250 a byte offset into an 'int'; it might overflow.
21251 See http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00483.html

21277 2011-04-14 Paul Eggert <eggert@cs.ucla.edu>
21279 Improve C-level modularity by making more things 'static'.

21695 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
21698 2011-04-13 Eli Zaretskii <eliz@gnu.org>
21700 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
21701 when at ZV. (Bug#8487)
21703 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
21705 * charset.c (Fclear_charset_maps): Use xfree instead of free.
21707 * keyboard.c (parse_tool_bar_item): Likewise.
21708 * sound.c (sound_cleanup, alsa_close): Likewise.
21709 * termcap.c (tgetent): Likewise.
21710 * xfns.c (x_default_font_parameter): Likewise.
21711 * xsettings.c (read_and_apply_settings): Likewise.
21713 * alloc.c (overrun_check_malloc, overrun_check_realloc)
21714 (overrun_check_free): Protoize.
21716 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
21718 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
21719 since callers should never pass a negative size.
21720 Change the signature to match that of plain 'read' and 'write'; see
21721 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
21722 * lisp.h: Update prototypes of emacs_write and emacs_read.
21724 2011-04-11 Eli Zaretskii <eliz@gnu.org>
21726 * xdisp.c (redisplay_window): Don't try to determine the character
21727 position of the scroll margin if the window start point w->startp
21728 is outside the buffer's accessible region. (Bug#8468)
21730 2011-04-10 Eli Zaretskii <eliz@gnu.org>
21732 Fix write-region and its subroutines for buffers > 2GB.
21733 * fileio.c (a_write, e_write): Modify declaration of arguments and
21734 local variables to support buffers larger than 2GB.
21735 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
21737 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
21738 argument, local variables, and return value.
21740 * lisp.h: Update prototypes of emacs_write and emacs_read.
21742 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
21744 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
21746 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
21748 Fix more problems found by GCC 4.6.0's static checks.
21750 * xdisp.c (vmessage): Use a better test for character truncation.
21752 * charset.c (load_charset_map): <, not <=, for optimization,
21753 and to avoid potential problems with integer overflow.
21754 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
21755 * casetab.c (set_identity, shuffle): Likewise.
21756 * editfns.c (Fformat): Likewise.
21757 * syntax.c (skip_chars): Likewise.
21759 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
21760 This also lets GCC 4.6.0 generate slightly better loop code.
21762 * callint.c (Fcall_interactively): <, not <=, for optimization.
21763 (Fcall_interactively): Count the number of arguments produced,
21764 not the number of arguments given. This is simpler and lets GCC
21765 4.6.0 generate slightly better code.
21767 * ftfont.c: Distingish more carefully between FcChar8 and char.
21768 The previous code passed unsigned char * to a functions like
21769 strlen and xstrcasecmp that expect char *, which does not
21770 conform to the C standard.
21771 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
21772 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
21773 char * when the C standard requires it.
21775 * keyboard.c (read_char): Remove unused var.
21777 * eval.c: Port to Windows vsnprintf (Bug#8435).
21778 Include <limits.h>.
21779 (SIZE_MAX): Define if the headers do not.
21780 (verror): Do not give up if vsnprintf returns a negative count.
21781 Instead, grow the buffer. This ports to Windows vsnprintf, which
21782 does not conform to C99. Problem reported by Eli Zaretskii.
21783 Also, simplify the allocation scheme, by avoiding the need for
21784 calling realloc, and removing the ALLOCATED variable.
21786 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
21788 Remove invocations of doprnt, as Emacs now uses vsnprintf.
21789 But keep the doprint source code for now, as we might revamp it
21790 and use it again (Bug#8435).
21791 * lisp.h (doprnt): Remove.
21792 * Makefile.in (base_obj): Remove doprnt.o.
21793 * deps.mk (doprnt.o): Remove.
21795 error: Print 32- and 64-bit integers portably (Bug#8435).
21796 Without this change, on typical 64-bit hosts error ("...%d...", N)
21797 was used to print both 32- and 64-bit integers N, which relied on
21798 undefined behavior.
21799 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
21800 * lisp.h (error, verror): Mark as printf-like functions.
21801 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
21802 Report overflow in size calculations when allocating printf buffer.
21803 Do not truncate output string at its first null byte.
21804 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
21805 Truncate the output at a character boundary, since vsnprintf does not
21807 * charset.c (check_iso_charset_parameter): Convert internal
21808 character to string before calling 'error', since %c now has the
21810 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
21811 overflow when computing char to be passed to 'error'. Do not
21812 pass Lisp_Object to 'error'; pass the integer instead.
21813 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
21814 formatted with plain %d.
21816 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
21818 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
21820 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
21822 * xterm.c (x_catch_errors): Remove duplicate declaration.
21824 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
21826 * xdisp.c, lisp.h (message_nolog): Remove; unused.
21828 2011-04-10 Jim Meyering <meyering@redhat.com>
21830 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
21831 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
21832 return ssize_t not "int", and use size_t as the buffer length.
21833 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
21834 * gnutls.h: Update declarations.
21835 * process.c (read_process_output): Use ssize_t, to match.
21836 (send_process): Likewise.
21838 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
21840 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
21842 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
21844 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
21845 Use unsigned char, to match FcChar8 type definition.
21847 * xterm.c (handle_one_xevent):
21848 * xmenu.c (create_and_show_popup_menu):
21849 * xselect.c (x_decline_selection_request)
21850 (x_reply_selection_request): Avoid type-punned deref of X events.
21852 2011-04-09 Eli Zaretskii <eliz@gnu.org>
21854 Fix some uses of `int' instead of EMACS_INT.
21855 * search.c (string_match_1, fast_string_match)
21856 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
21857 (scan_buffer, find_next_newline_no_quit)
21858 (find_before_next_newline, search_command, Freplace_match)
21859 (Fmatch_data): Make some `int' variables be EMACS_INT.
21861 * xdisp.c (display_count_lines): 3rd argument and return value now
21862 EMACS_INT. All callers changed.
21863 (pint2hrstr): Last argument is now EMACS_INT.
21865 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
21866 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
21867 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
21868 (decode_coding_utf_16, decode_coding_emacs_mule)
21869 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
21870 (decode_coding_ccl, decode_coding_charset)
21871 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
21872 (decode_coding_iso_2022, decode_coding_emacs_mule)
21873 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
21874 <char_offset, last_offset>: Declare EMACS_INT.
21875 (encode_coding_utf_8, encode_coding_utf_16)
21876 (encode_coding_emacs_mule, encode_invocation_designation)
21877 (encode_designation_at_bol, encode_coding_iso_2022)
21878 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
21879 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
21881 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
21882 (encode_invocation_designation): Last argument P_NCHARS is now
21884 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
21885 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
21887 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
21890 * ccl.c (Fccl_execute_on_string): Declare some variables
21893 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
21895 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
21897 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
21899 * process.c (Fformat_network_address): Doc fix.
21901 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
21903 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
21905 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
21907 * keyboard.c (read_char): Call Lisp function help-form-show,
21908 instead of using internal_with_output_to_temp_buffer.
21909 (Qhelp_form_show): New var.
21910 (syms_of_keyboard): Use DEFSYM macro.
21912 * print.c (internal_with_output_to_temp_buffer): Function deleted.
21914 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
21916 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
21918 * process.c (Flist_processes): Remove to Lisp.
21919 (list_processes_1): Delete.

21923 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
21925 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
21927 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
21929 Fix more problems found by GCC 4.6.0's static checks.

21933 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
21935 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
21937 * xdisp.c (vmessage): Mark as a printf-like function.
21939 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
21941 * sound.c (sound_warning): Don't crash if arg contains a printf format.
21943 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
21944 printf-like functions.
21945 (tiff_load): Add casts to remove these marks before passing them
21946 to system-supplied API.
21948 * eval.c (Fsignal): Remove excess argument to 'fatal'.
21950 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
21951 This avoids several warnings with gcc -Wstrict-overflow.
21952 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
21953 directly, rather than having caller test rule sign. This avoids
21954 some unnecessary tests.
21955 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
21956 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
21957 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
21959 * xfont.c (xfont_text_extents): Remove var that was set but not used.
21960 (xfont_open): Avoid unnecessary tests.
21962 * composite.c (composition_gstring_put_cache): Use unsigned integer.
21964 * composite.h, composite.c (composition_gstring_put_cache):
21965 Use EMACS_INT, not int, for length.

21968 breaking out part of COMPOSITION_DECODE_RULE.
21969 (COMPOSITION_DECODE_RULE): Use it.

21971 by using the new macro.
21973 * textprop.c (set_text_properties_1): Change while to do-while,
21974 since the condition is always true at first.
21976 * intervals.c (graft_intervals_into_buffer): Mark var as used.
21977 (interval_deletion_adjustment): Return unsigned value.
21980 * process.c (list_processes_1, create_pty, read_process_output):

21990 (update_syntax_table): Use unsigned instead of int.
21992 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
21993 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
21994 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
21996 * print.c (print_error_message): Avoid int overflow.
21998 * font.c (font_list_entities): Redo for clarity,
21999 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
22001 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
22002 (font_score): Avoid potential overflow in diff calculation.
22004 * fns.c (substring_both): Remove var that is set but not used.
22005 (sxhash): Redo loop for clarity and to avoid wraparound warning.
22007 * eval.c (funcall_lambda): Rename local to avoid shadowing.
22009 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
22010 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
22011 can always succeed if overflow has undefined behavior.
22013 * search.c (boyer_moore, wordify): Remove vars set but not used.
22014 (wordify): Omit three unnecessary tests.
22016 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
22017 All callers changed. This avoids the need for an unused var.
22019 * casefiddle.c (casify_region): Remove var that is set but not used.
22021 * dired.c (file_name_completion): Remove var that is set but not used.
22023 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
22025 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
22026 (Finsert_file_contents): Remove unnecessary code checking fd.
22028 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
22029 Check for integer overflow on size calculations.
22031 * buffer.c (Fprevious_overlay_change): Remove var that is set
22034 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
22035 Remove vars that are set but not used.
22036 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
22037 (timer_check_2): Mark vars as initialized.
22039 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
22041 * image.c (lookup_image): Remove var that is set but not used.
22042 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
22044 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
22045 that are set but not used.
22047 * xfns.c (make_invisible_cursor): Don't return garbage
22048 if XCreateBitmapFromData fails (Bug#8410).
22050 * xselect.c (x_get_local_selection, x_handle_property_notify):
22051 Remove vars that are set but not used.

22063 (map_tty_color) [!defined MSDOS]: Likewise.
22065 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
22067 * coding.c: Remove vars that are set but not used.
22068 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
22069 All callers changed.
22070 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
22071 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
22072 (decode_coding_charset): Remove vars that are set but not used.
22074 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
22075 that is set but not used.
22077 * print.c (print_object): Remove var that is set but not used.
22079 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
22080 The gnulib version avoids calling malloc in the usual case,
22081 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
22082 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
22083 * filelock.c (current_lock_owner): Likewise.
22084 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
22085 * sysdep.c: Include allocator.h, careadlinkat.h.
22086 (emacs_no_realloc_allocator): New static constant.
22087 (emacs_readlink): New function.
22088 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
22089 ../lib/careadlinkat.h.
22091 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
22093 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
22094 first non-nil return value).

22098 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
22099 if not defined (Bug#8403).

22103 * xdisp.c (display_count_lines): Remove parameter `start',
22104 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.

22108 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
22109 and thereabouts. All callers changed.
22110 (get_per_char_metric): Remove parameter `f', unused since
22111 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

22115 do not dereference NULL upon failed strdup
22116 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
22117 (ns_get_family): Likewise.
22119 2011-04-02 Juanma Barranquero <lekktu@gmail.com>

22155 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
22156 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
22157 (FletX, Flet): Obey lexical binding.
22158 (Fcommandp): Handle closures.
22159 (Feval): New `lexical' arg.
22160 (eval_sub): New function extracted from Feval. Use it almost
22161 everywhere where Feval was used. Look up vars in lexical env.
22163 (Ffunctionp): Move from subr.el.
22164 (Ffuncall): Handle closures.
22165 (apply_lambda): Remove `eval_flags'.
22166 (funcall_lambda): Handle closures and new byte-code-functions.
22167 (Fspecial_variable_p): New function.
22168 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
22169 but without exporting it to Lisp.
22171 * doc.c (Fdocumentation, store_function_docstring):
22172 * data.c (Finteractive_form): Handle closures.
22174 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
22177 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
22179 (exec_byte_code): New function extracted from Fbyte_code to handle new
22180 calling convention for byte-code-functions. Add new byte-codes.
22182 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
22184 * alloc.c (Fmake_symbol): Init new `declared_special' field.
22186 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
22188 * xdisp.c (redisplay_internal): Fix prototype.
22190 2011-03-31 Eli Zaretskii <eliz@gnu.org>
22192 * xdisp.c (SCROLL_LIMIT): New macro.
22193 (try_scrolling): Use it when setting scroll_limit.
22194 Limit scrolling to 100 screen lines.
22195 (redisplay_window): Even when falling back on "recentering",
22196 position point in the window according to scroll-conservatively,
22197 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
22199 (try_scrolling): When point is above the window, allow searching
22200 as far as scroll_max, or one screenful, to compute vertical
22201 distance from PT to the scroll margin position. This prevents
22202 try_scrolling from unnecessarily failing when
22203 scroll-conservatively is set to a value slightly larger than the
22204 window height. Clean up the case of PT below the margin at bottom
22205 of window: scroll_max can no longer be INT_MAX. When aggressive
22206 scrolling is in use, don't let point enter the opposite scroll
22207 margin as result of the scroll.
22208 (syms_of_xdisp) <scroll-conservatively>: Document the
22209 threshold of 100 lines for never-recentering scrolling.
22211 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
22213 * dispextern.h (move_it_by_lines):
22214 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
22215 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
22216 (message_log_check_duplicate): Remove parameters `prev_bol' and
22217 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
22218 (redisplay_internal): Remove parameter `preserve_echo_area',
22219 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
22221 * indent.c (Fvertical_motion):
22222 * window.c (window_scroll_pixel_based, Frecenter):
22223 Don't pass `need_y_p' to `move_it_by_lines'.
22225 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
22227 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
22228 steal a few bits to be more compact.
22229 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
22230 Remove unneeded casts.
22232 * bytecode.c (Fbyte_code): CAR and CDR can GC.
22234 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
22236 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
22237 binding" message (bug#7967).
22239 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
22241 Fix more problems found by GCC 4.6.0's static checks.
22243 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
22244 Remove unused local var.
22246 * editfns.c (Fmessage_box): Remove unused local var.
22248 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
22249 (note_mode_line_or_margin_highlight, note_mouse_highlight):
22250 Omit unused local vars.
22251 * window.c (shrink_windows): Omit unused local var.
22252 * menu.c (digest_single_submenu): Omit unused local var.
22253 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
22254 Omit unused local var.
22256 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
22257 Don't assume string length fits in int.
22258 (keyremap_step, read_key_sequence): Use size_t for sizes.
22259 (read_key_sequence): Don't check last_real_key_start redundantly.
22261 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
22262 instead of alloca (Bug#8344).
22264 * eval.c (Fbacktrace): Don't assume nargs fits in int.
22265 (Fbacktrace_frame): Don't assume nframes fits in int.
22267 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
22269 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
22272 * term.c (produce_glyphless_glyph): Remove unnecessary test.
22274 * cm.c (calccost): Turn while-do into do-while, for clarity.
22276 * keyboard.c (syms_of_keyboard): Use the same style as later
22277 in this function when indexing through an array. This also
22278 works around GCC bug 48267.
22280 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
22282 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
22284 * chartab.c (sub_char_table_ref_and_range): Redo for slight
22285 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
22287 * keyboard.c, keyboard.h (num_input_events): Now size_t.
22288 This avoids undefined behavior on integer overflow, and is a bit
22289 more convenient anyway since it is compared to a size_t variable.
22291 Variadic C functions now count arguments with size_t, not int.
22292 This avoids an unnecessary limitation on 64-bit machines, which
22293 caused (substring ...) to crash on large vectors (Bug#8344).
22294 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
22295 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
22296 All variadic functions and their callers changed accordingly.
22297 (struct gcpro.nvars): Now size_t, not int. All uses changed.

22299 * editfns.c (general_insert_function): Likewise.
22300 * eval.c (struct backtrace.nargs, interactive_p)
22301 (internal_condition_case_n, run_hook_with_args, apply_lambda)
22302 (funcall_lambda, mark_backtrace): Likewise.
22303 * fns.c (concat): Likewise.
22304 * frame.c (x_set_frame_parameters): Likewise.
22305 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
22306 0 if not found, not -1. All callers changed.
22308 * alloc.c (garbage_collect): Don't assume stack size fits in int.
22309 (stack_copy_size): Now size_t, not int.
22310 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
22312 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
22314 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
22315 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
22316 All callers changed.
22318 * lisp.h (multibyte_char_to_unibyte):
22319 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
22320 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
22321 * character.h (CHAR_TO_BYTE8):
22322 * cmds.c (internal_self_insert):
22323 * editfns.c (general_insert_function):
22324 * keymap.c (push_key_description):
22325 * search.c (Freplace_match):
22326 * xdisp.c (message_dolog, set_message_1): All callers changed.
22328 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
22330 * keyboard.c (safe_run_hook_funcall): New function.
22331 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
22332 don't set the hook to nil, but remove the offending function instead.
22333 (Qcommand_hook_internal): Remove, unused.
22334 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
22335 Vcommand_hook_internal.
22337 * eval.c (enum run_hooks_condition): Remove.
22338 (funcall_nil, funcall_not): New functions.
22339 (run_hook_with_args): Call each function through a `funcall' argument.
22340 Remove `cond' argument, now redundant.
22341 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
22342 (Frun_hook_with_args_until_failure): Adjust accordingly.
22343 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
22345 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
22347 * dispextern.h (string_buffer_position): Remove declaration.
22349 * print.c (strout): Remove parameter `multibyte', unused since
22350 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
22352 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
22353 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
22354 All callers changed.
22356 * w32.c (_wsa_errlist): Use braces for struct initializers.
22358 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
22359 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
22360 All callers changed.
22361 (string_buffer_position): Likewise. Also, make static (it's never
22362 used outside xdisp.c).
22363 (cursor_row_p): Remove parameter `w', unused since
22364 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.

22366 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
22367 All callers changed.
22369 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
22371 * nsterm.m (syms_of_nsterm): Use doc: for ns-auto-hide-menu-bar.
22373 2011-03-27 Anders Lindgren <andlind@gmail.com>
22375 * nsterm.m (ns_menu_bar_is_hidden): New variable.
22376 (ns_constrain_all_frames, ns_menu_bar_should_be_hidden)
22377 (ns_update_auto_hide_menu_bar): New functions.
22378 (ns_update_begin): Call ns_update_auto_hide_menu_bar.

22382 (syms_of_nsterm): DEFVAR ns-auto-hide-menu-bar, init to Qnil.
22384 2011-03-27 Jan Djärv <jan.h.d@swipnet.se>
22386 * nsmenu.m (runDialogAt): Remove argument to timer_check.
22388 2011-03-27 Glenn Morris <rgm@gnu.org>
22390 * syssignal.h: Replace RETSIGTYPE with void.
22391 * atimer.c, data.c, dispnew.c, emacs.c, floatfns.c, keyboard.c:
22392 * keyboard.h, lisp.h, process.c, sysdep.c, xterm.c:
22393 Replace SIGTYPE with void everywhere.
22394 * s/usg5-4-common.h (SIGTYPE): Remove definition.
22395 * s/template.h (SIGTYPE): Remove commented out definition.
22397 2011-03-26 Eli Zaretskii <eliz@gnu.org>
22399 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
22400 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
22402 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
22404 * w32.c (read_unc_volume): Use parameter `henum', instead of
22405 global variable `wget_enum_handle'.
22407 * keymap.c (describe_vector): Remove parameters `indices' and
22408 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.
22409 (describe_map, Fdescribe_vector): Adjust calls to `describe_vector'.
22411 * keyboard.h (timer_check, show_help_echo): Remove unused parameters.
22413 * keyboard.c (timer_check): Remove parameter `do_it_now',
22414 unused since 1996-04-12T06:01:29Z!rms@gnu.org.
22415 (show_help_echo): Remove parameter `ok_to_overwrite_keystroke_echo',
22416 unused since 2008-04-19T19:30:53Z!monnier@iro.umontreal.ca.
22418 * keyboard.c (read_char):
22419 * w32menu.c (w32_menu_display_help):
22420 * xmenu.c (show_help_event, menu_help_callback):
22421 Adjust calls to `show_help_echo'.
22423 * gtkutil.c (xg_maybe_add_timer):
22424 * keyboard.c (readable_events):
22425 * process.c (wait_reading_process_output):
22426 * xmenu.c (x_menu_wait_for_event): Adjust calls to `timer_check'.
22428 * insdel.c (adjust_markers_gap_motion):
22429 Remove; no-op since 1998-01-02T21:29:48Z!rms@gnu.org.
22430 (gap_left, gap_right): Don't call it.
22432 2011-03-25 Chong Yidong <cyd@stupidchicken.com>
22434 * xdisp.c (handle_fontified_prop): Discard changes to clip_changed
22435 incurred during fontification.

22476 2011-03-24 Juanma Barranquero <lekktu@gmail.com>
22478 * w32term.c (x_set_glyph_string_clipping):
22479 Don't pass uninitialized region to CombineRgn.
22481 2011-03-23 Juanma Barranquero <lekktu@gmail.com>
22483 * w32fns.c (x_set_menu_bar_lines): Remove unused variable `olines'.
22484 (w32_wnd_proc): Pass NULL to Windows API, not uninitialized buffer.
22485 (Fx_close_connection): Remove unused variable `i'.
22487 * w32font.c (w32font_draw): Return number of glyphs.

22503 2011-03-23 Julien Danjou <julien@danjou.info>
22505 * term.c (Fsuspend_tty, Fresume_tty):
22506 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
22507 * window.c (temp_output_buffer_show):
22508 * insdel.c (signal_before_change):
22509 * frame.c (Fhandle_switch_frame):
22510 * fileio.c (Fdo_auto_save):
22511 * emacs.c (Fkill_emacs):
22512 * editfns.c (save_excursion_restore):
22513 * cmds.c (internal_self_insert):
22514 * callint.c (Fcall_interactively):
22515 * buffer.c (Fkill_all_local_variables):
22516 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
22518 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
22519 unconditionally since it does the check itself.
22521 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
22523 Fix more problems found by GCC 4.5.2's static checks.
22525 * coding.c (encode_coding_raw_text): Avoid unnecessary test
22526 the first time through the loop, since we know p0 < p1 then.
22527 This also avoids a gcc -Wstrict-overflow warning.
22529 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
22530 leading to a memory leak, possible in functions like
22531 load_charset_map_from_file that can allocate an unbounded number
22532 of objects (Bug#8318).
22534 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
22535 that could (at least in theory) be that large.
22537 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
22538 This is less likely to overflow, and avoids undefined behavior if
22539 overflow does occur. All callers changed. Use strtoul to scan
22540 for the unsigned long integer.
22541 (pint2hrstr): Simplify and tune code slightly.
22542 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
22544 * scroll.c (do_scrolling): Work around GCC bug 48228.
22545 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
22547 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
22548 This also avoids a warning with gcc -Wstrict-overflow.
22549 (validate_x_resource_name): Simplify count usage.
22550 This also avoids a warning with gcc -Wstrict-overflow.
22552 * fileio.c (Fcopy_file): Report error if fchown or fchmod
22555 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
22557 * process.c (Fmake_network_process): Use socklen_t, not int,
22558 where POSIX says socklen_t is required in portable programs.
22559 This fixes a porting bug on hosts like 64-bit HP-UX, where
22560 socklen_t is wider than int (Bug#8277).
22561 (Fmake_network_process, server_accept_connection):
22562 (wait_reading_process_output, read_process_output):
22565 * process.c: Rename or move locals to avoid shadowing.
22566 (list_processes_1, Fmake_network_process):
22567 (read_process_output_error_handler, exec_sentinel_error_handler):
22568 Rename or move locals.
22569 (Fmake_network_process): Define label "retry_connect" only if needed.
22570 (Fnetwork_interface_info): Fix pointer signedness.
22571 (process_send_signal): Add cast to avoid pointer signedness problem.
22572 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
22573 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
22575 Make tparam.h and terminfo.c consistent.
22576 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
22577 Include tparam.h instead, since it declares them.
22578 * cm.h (PC): Remove extern decl; tparam.h now does this.
22579 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
22580 * terminfo.c: Include tparam.h, to check interfaces.
22581 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
22582 (tparam): Adjust signature to match interface in tparam.h;
22583 this removes some undefined behavior. Check that outstring and len

22639 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
22641 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
22642 This should get cleaned up, so that child_setup has the
22643 same signature on all platforms.
22645 * callproc.c (call_process_cleanup): Now static.
22646 (relocate_fd): Rename locals to avoid shadowing.

22777 some of which prompt warnings from gcc -Wbad-function-cast.

22807 (Fmemory_limit): Cast sbrk's returned value to char *.
22809 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

22817 to use the following functions instead of these macros.
22818 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
22819 EMACS_INT, since callers assume the returned value fits in int.
22820 (upcase1): Likewise, for UPCASE_TABLE.
22821 (uppercasep, lowercasep, upcase): New static inline functions.
22822 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

22832 (regex_compile, re_match_2_internal): Mark locals as initialized.
22833 (RETALLOC_IF): Define only if needed.
22834 (WORDCHAR_P): Likewise. This one is never needed, but is used
22835 only in a comment talking about a compiler bug, so put inside
22836 the #if 0 of that comment.
22837 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
22838 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):

22865 New macros, so that the caller can use some names other than
22866 gcpro1, gcpro2, etc.
22867 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
22869 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
22870 argument, for consistency with GCPRO2_VAR, etc: it is now the
22871 prefix of the variable, not the variable itself. All uses
22873 * dired.c (directory_files_internal, file_name_completion):
22874 Rename locals to avoid shadowing.
22876 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
22877 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
22878 dired.c's scmp function, had undefined behavior.
22879 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
22880 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
22881 * buffer.h: ... to here, because these macros use current_buffer,
22882 and the new implementation with inline functions needs to have
22883 current_buffer in scope now, rather than later when the macros
22885 (downcase, upcase1): New static inline functions.
22886 (DOWNCASE, UPCASE1): Reimplement using these functions.
22887 This avoids undefined behavior in expressions like
22888 DOWNCASE (x) == DOWNCASE (y), which previously suffered
22889 from race conditions in accessing the global variables
22890 case_temp1 and case_temp2.
22891 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
22892 * lisp.h (case_temp1, case_temp2): Remove their decls.
22893 * character.h (ASCII_CHAR_P): Move from here ...
22894 * lisp.h: ... to here, so that the inline functions mentioned
22895 above can use them.

22902 (file_name_as_directory): Use const pointers when appropriate.
22903 (Fexpand_file_name): Likewise. In particular, newdir might
22904 point at constant storage, so make it a const pointer.

22906 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
22908 (Fset_file_times, Finsert_file_contents, auto_save_error):

22913 to avoid shadowing.
22915 * marker.c (bytepos_to_charpos): Remove; unused.
22917 * lisp.h (verify_bytepos, count_markers): New decls,
22918 so that gcc does not warn that these functions aren't declared.
22920 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
22921 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
22922 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
22923 (copy_text): Remove unused local var.

22926 (lock_file_1): Rename local to avoid shadowing.
22928 * buffer.c (fix_overlays_before): Mark locals as initialized.
22929 (fix_start_end_in_overlays): Likewise. This function should be
22930 simplified by using pointers-to-pointers, but that's a different
22932 (switch_to_buffer_1): Now static.
22933 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
22934 (report_overlay_modification): Rename locals to avoid shadowing.

22937 Fix pointer signedness issue.
22938 (sys_subshell): Mark local as volatile if checking for lint,
22939 to suppress a gcc -Wclobbered warning that does not seem to be right.
22940 (MAXPATHLEN): Define only if needed.
22942 * process.c (serial_open, serial_configure): Move decls from here ...
22943 * systty.h: ... to here, so that they can be checked.
22945 * fns.c (get_random, seed_random): Move extern decls from here ...
22946 * lisp.h: ... to here, so that they can be checked.
22948 * sysdep.c (reset_io): Now static.
22949 (wait_for_termination_signal): Remove; unused.
22951 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):

22955 (DENSE_TABLE_SIZE): Remove; unused.
22956 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
22957 (describe_map_tree):
22958 Rename locals to avoid shadowing.
22960 * keyboard.c: Declare functions static if they are not used elsewhere.
