29 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
30
31 Fix integer width and related bugs (Bug#9874).
32 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
33 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)

47 int might not be wide enough.
48 (bidi_cache_search, bidi_cache_find, bidi_init_it)
49 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)
50 (bidi_at_paragraph_end, bidi_find_paragraph_start)
51 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
52 (bidi_level_of_next_char, bidi_move_to_visually_next):

54 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
55 (Fkill_buffer, Fset_buffer_major_mode)
56 (advance_to_char_boundary, Fbuffer_swap_text)
57 (Fset_buffer_multibyte, overlays_at, overlays_in)
58 (overlay_touches_p, struct sortvec, record_overlay_string)
59 (overlay_strings, recenter_overlay_lists)
60 (adjust_overlays_for_insert, adjust_overlays_for_delete)
61 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
62 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
63 (Foverlay_recenter, last_overlay_modification_hooks_used)
64 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
65 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
66 (validate_region): Omit unnecessary test for b <= e,
67 since that's guaranteed by the previous test.
68 (adjust_overlays_for_delete): Avoid pos + length overflow.
69 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
70 (report_overlay_modification):

72 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
73 Omit pointer cast, which isn't needed anyway, and doesn't work
74 after the EMACS_INT -> ptrdiff_t change.
75 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
76 * buffer.h: Adjust decls to match defn changes elsewhere.

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

99 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
100 (casify_object): Avoid integer overflow when overallocating buffer.
101 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
102 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
103 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
104 * category.h (CATEGORYP): Don't assume arg is nonnegative.
105 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
106 integers are now checked earlier. All uses replaced with XINT.
107 (ccl_driver):
108 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
109 For CCL_MapSingle, check that content and value are in int range.
110 (ccl_driver, Fregister_code_conversion_map):
111 Check that Vcode_version_map_vector is a vector.
112 (resolve_symbol_ccl_program): Check that vector header is in range.
113 Always copy the vector, so that we can check its contents reliably
114 now rather than having to recheck each instruction as it's being
115 executed. Check that vector words fit in 'int'.
116 (ccl_get_compiled_code, Fregister_ccl_program)
117 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
118 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
119 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
120 contents are in range.
121 (Fccl_execute_on_string): Check that status is in range.
122 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
123 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
124 Accept and return EMACS_INT, not int, because callers can pass values
125 out of 'int' range.
126 (c_string_width, strwidth, lisp_string_width, chars_in_text)
127 (multibyte_chars_in_text, parse_str_as_multibyte)
128 (str_as_multibyte, count_size_as_multibyte, str_to_multibyte)
129 (str_as_unibyte, str_to_unibyte, string_count_byte8)
130 (string_escape_byte8, Fget_byte):
131 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
132 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
133 avoid mishandling large integers.
134 * character.h: Adjust decls to match defn changes elsewhere.
135 * charset.c (load_charset_map_from_file, find_charsets_in_text)
136 (Ffind_charset_region):
137 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
138 (load_charset_map_from_file): Redo idx calculation to avoid overflow.
139 (load_charset_map_from_vector, Fdefine_charset_internal):
140 Don't assume fixnum fits in int.
141 (load_charset_map_from_vector, Fmap_charset_chars):
142 Remove now-unnecessary CHECK_NATNUMs.
143 (Fdefine_charset_internal): Check ranges here, more carefully.
144 Don't rely on undefined behavior with signed left shift overflow.
145 Don't assume unsigned int fits into fixnum, or that fixnum fits
146 into unsigned int. Don't require max_code to be a valid fixnum;
147 that's not true for gb10830 4-byte on a 32-bit host. Allow
148 invalid_code to be a cons, for the same reason. Require code_offset
149 to be a character. Avoid int overflow if max_char is close
150 to INT_MAX.
151 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
152 this is intended anyway and avoids some undefined behavior.
153 (load_charset_map): Pass unsigned, not int, as 2nd arg of
154 INDEX_TO_CODE_POINT, as that's what it expects.
155 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
156 * charset.h (DECODE_CHAR): Return int, not unsigned;
157 this is what was intended anyway, and it avoids undefined behavior.
158 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
159 integer-overflow issues.
160 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
161 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
162 where the argument is EMACS_INT, and this behavior is not intended.
163 * chartab.c (Fmake_char_table, Fset_char_table_range)
164 (uniprop_get_decoder, uniprop_get_encoder):
165 Don't assume fixnum fits in int.
166 * cmds.c (move_point): New function, that does the gist of
167 Fforward_char and Fbackward_char, but does so while checking
168 for integer overflow more accurately.
169 (Fforward_char, Fbackward_char): Use it.
170 (Fforward_line, Fend_of_line, internal_self_insert)
171 (internal_self_insert):
172 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
173 Fix a FIXME, by checking for integer overflow when calculating
174 target_clm and actual_clm.
175 * coding.c (detect_coding_XXX, encode_coding_XXX, CODING_DECODE_CHAR)

212 result of ENCODE_CHAR.

821 (x_emacs_to_x_modifiers): Use EMACS_INT, not int, because values
822 may come from Lisp.
823 (handle_one_xevent): NATNUMP can eval its arg twice.
824 (x_connection_closed):
825 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
826 * xterm.h: Adjust decls to match defn changes elsewhere.
827 (struct scroll_bar): Use struct vectorlike_header
828 rather than rolling our own approximation.
829 (SCROLL_BAR_VEC_SIZE): Remove; not used.
830
831 2012-05-25 Glenn Morris <rgm@gnu.org>
832

834
835 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
836
837 * lread.c: Remove `read_pure' which makes no difference.
838 (read_pure): Remove var.
839 (unreadpure): Remove function.
840 (readevalloop): Don't call read_list with -1 flag.
841 (read1, read_vector): Don't test read_pure any more.
842 (read_list): Simplify.
843
844 * fileio.c, character.h: Minor style tweaks.
845
846 2012-05-24 Dmitry Antipov <dmantipov@yandex.ru>
847

851
852 * makefile.w32-in: Follow-up to 2012-05-22T16:20:27Z!eggert@cs.ucla.edu.
853 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
854
855 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
856
857 Remove src/m/*.
858 This directory predates autoconf and is no longer needed nowadays.
859 Move its few remaining bits of functionality to where they're needed.
860 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:
861 * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:
862 * m/template.h: Remove.
863 * Makefile.in (M_FILE): Remove. All uses removed.
864 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS):
865 * lisp.h (USE_LSB_TAG):
866 * mem-limits.h (EXCEEDS_LISP_PTR):
867 Use VAL_MAX, not VALBITS, in #if.
868 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
869 (EMACS_UINT): Define unconditionally now.
870 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
871 (BITS_PER_EMACS_INT): New constants, replacing
872 what used to be in config.h, but not useful in #if.
873 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
874 define them any more.
875 (VAL_MAX): New macro.
876 (VALMASK): Use it.
877 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
878 BITS_PER_EMACS_INT, in #if.
879 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
880 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
881 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
882 * s/ms-w32.h (DATA_START):
883 Move here from removed file m/intel386.h.
884 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
885 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
886
887 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
888
889 Assume C89 or later.
890 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
891 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
892 (xrealloc):
893 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.
894 * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):
895 * textprop.c, tparam.c (NULL): Remove.
896 * ralloc.c, vm-limit.c (POINTER): Assume void * works.
897 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
898 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
899 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
900 * xterm.c (input_signal_count): Assume volatile works.
901
902 2012-05-21 Ken Brown <kbrown@cornell.edu>
903
904 * xgselect.c (xg_select): Fix first argument in call to 'select'

915 * xterm.h (x_in_use): Declare.
916 * xgselect.c: Include xterm.h.
917 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
918 and `display_arg' (bug#9754).
919
920 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
921
922 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
923
924 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
925 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
926
927 2012-05-18 Eli Zaretskii <eliz@gnu.org>
928
929 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
930

932 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c
933
934 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
935 reference to image_cache->refcount.
936 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
937
938 2012-05-17 Juri Linkov <juri@jurta.org>
939
940 * search.c (Fword_search_regexp, Fword_search_backward)
941 (Fword_search_forward, Fword_search_backward_lax)
942 (Fword_search_forward_lax): Move functions to isearch.el
943 (bug#10145, bug#11381).
944
945 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
946
947 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
948
949 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
950
951 * lread.c (init_obarray): Declare Qt and Qnil as special.
952
953 2012-05-14 Glenn Morris <rgm@gnu.org>
954
955 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
956 Put "libexec" before "bin", for the sake of init_callproc_1.
957
958 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
959
960 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
961
962 * unexaix.c: Port to more-recent AIX compilers.
963 (report_error, report_error_1, make_hdr, copy_sym)
964 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
965 Make arguments const char *, not char *, to avoid violations of C
966 standard and to fix some AIX warnings reported by Gilles Pion.
967
968 2012-05-14 Eli Zaretskii <eliz@gnu.org>
969
970 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
971 already have overlays loaded.
972 (handle_single_display_spec): Before returning without displaying
973 fringe bitmap, synchronize the bidi iterator with the main display
974 iterator, by calling iterate_out_of_display_property.
975 (iterate_out_of_display_property): Detect buffer iteration by
976 testing that it->string is a Lisp string.
977 (get_next_display_element): When the current object is exhausted,
978 and there's something on it->stack, call set_iterator_to_next to
979 proceed with what's on the stack, instead of returning zero.
980 (set_iterator_to_next): If called at the end of a Lisp string,
981 proceed to consider_string_end without incrementing string
982 position. Don't increment display vector index past the end of
983 the display vector. (Bug#11417)
984 (pos_visible_p): Don't report a position visible when move_it_to
985 stopped at the last line of window, which happens to be scanned
986 backwards by the bidi iteration. (Bug#11464)
987
988 2012-05-14 Eli Zaretskii <eliz@gnu.org>
989
990 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
991 and right-margin display specs even if the spec is invalid or we
992 are on a TTY, and thus unable to display on the fringes. That's
993 because the text with the property will not be displayed anyway,
994 so we need to signal to the caller that this is a "replacing"
995 display spec. This fixes display when the spec is invalid or we
996 are on a TTY.
997
998 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
999
1000 * unexaix.c (make_hdr): Fix typo in prototype.
1001 This bug broke the build on AIX. Problem reported by Gilles Pion.
1002
1003 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
1004
1005 * keyboard.c (kbd_buffer_get_event): Read special events also in
1006 batch mode. (Bug#11415)
1007
1008 2012-05-12 Glenn Morris <rgm@gnu.org>
1009
1010 * ns.mk: Update for ns_appbindir no longer having trailing "/".
1011
1012 2012-05-12 Eli Zaretskii <eliz@gnu.org>
1013
1014 * lisp.mk (lisp): Add newcomment.elc.
1015
1016 2012-05-12 Glenn Morris <rgm@gnu.org>
1017
1018 * Makefile.in (MKDIR_P): New, set by configure.
1019 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
1020
1021 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
1022
1023 Remove unused function hourglass_started.
1024 * dispextern.h (hourglass_started):
1025 * w32fns.c (hourglass_started):
1026 * xdisp.c (hourglass_started): Remove.
1027
1028 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
1029
1030 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
1031 Update dependencies.
1032
1033 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
1034
1035 * xgselect.c (xg_select): Put maxfds+1 into a var.
1036 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
1037
1038 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
1039
1040 2012-05-10 Dave Abrahams <dave@boostpro.com>
1041
1042 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
1043 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
1044
1045 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
1046
1047 * dbusbind.c (xd_registered_buses): New internal Lisp object.
1048 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
1049 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
1050 Initialize xd_registered_buses.
1051
1052 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
1053
1054 Untag more efficiently if USE_LSB_TAG.
1055 This is based on a proposal by YAMAMOTO Mitsuharu in
1056 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
1057 For an admittedly artificial (nth 8000 longlist) benchmark on
1058 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
1059 Emacs's overall text size by 1%.
1060 * lisp.h (XUNTAG): New macro.
1061 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
1062 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
1063 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
1064 * eval.c (Fautoload):
1065 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
1066 * frame.h (XFRAME): Use XUNTAG.
1067
1068 Port recent dbusbind.c changes to 32-bit --with-wide-int.
1069 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
1070 Remove unportable assumptions about print widths of types like
1071 dbus_uint32_t.
1072 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
1073 intptr_t when converting between pointer and integer, to avoid GCC
1074 warnings about wrong width.
1075
1076 2012-05-09 Eli Zaretskii <eliz@gnu.org>
1077
1078 * w32proc.c (new_child): Force Windows to reserve only 64KB of
1079 stack for each reader_thread, instead of defaulting to 8MB
1080 determined by the linker. This avoids failures in creating
1081 subprocesses on Windows 7, see the discussion in this thread:
1082 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
1083
1084 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
1085
1086 Fix up display of the *Minibuf-0* buffer in the mini window.
1087 * keyboard.c (read_char): Don't clear the echo area if there's no
1088 message to clear.
1089 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
1090 contents of *Minibuf-0*) if there's no message displayed in its stead.
1091
1092 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
1093
1094 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
1095 batch mode.
1096
1097 2012-05-06 Chong Yidong <cyd@gnu.org>
1098
1099 * lisp.mk (lisp): Update.
1100
1101 2012-05-05 Jim Meyering <meyering@redhat.com>
1102
1103 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
1104
1105 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
1106
1107 * data.c (PUT_ERROR): New macro.
1108 (syms_of_data): Use it. Add new error type `user-error'.
1109 * undo.c (user_error): New function.
1110 (Fprimitive_undo): Use it.
1111 * print.c (print_error_message): Adjust print style for `user-error'.
1112 * keyboard.c (user_error): New function.
1113 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
1114
1115 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
1116
1117 Do not limit current-time-string to years 1000..9999.
1118 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
1119 (Fcurrent_time_string): Support any year that is supported by the
1120 underlying localtime representation. Don't use asctime, as it
1121 has undefined behavior for years outside the range -999..9999.
1122
1123 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
1124
1125 Fix race conditions involving setenv, gmtime, localtime, asctime.
1126 Without this fix, interrupts could mess up code that uses these
1127 nonreentrant functions, since setting TZ invalidates existing
1128 tm_zone or tzname values, and since most of these functions return
1129 pointers to static storage.
1130 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
1131 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
1132 Grow the critical sections to include not just invoking
1133 localtime/gmtime, but also accessing these functions' results
1134 including their tm_zone values if any, and any related TZ setting.
1135 (format_time_string): Last arg is now struct tm *, not struct tm **,
1136 so that the struct tm is saved in the critical section.
1137 All callers changed. Simplify allocation of initial buffer, partly
1138 motivated by the fact that memory allocation needs to be outside
1139 the critical section.
1140
1141 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
1142
1143 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'

1154
1155 2012-05-02 Eli Zaretskii <eliz@gnu.org>
1156
1157 * xdisp.c (pos_visible_p): If already at a newline from the
1158 display string before the 'while' loop, don't walk back the glyphs
1159 from it3.glyph_row. Solves assertion violation when the display
1160 string begins with a newline (egg.el). (Bug#11367)
1161
1162 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
1163

1172 All were removed before 23.1.
1173
1174 * dispnew.c: Remove HAVE_LIBNCURSES test;
1175 it is always true on relevant platforms.
1176
1177 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
1178 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
1179

1189
1190 Do not avoid creating empty evaporating overlays (Bug#9642).
1191 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
1192 That is, do not delete an evaporating overlay if it becomes
1193 empty after its bounds are adjusted to fit within its buffer.
1194 This fix caused other problems, and I'm reverting it until we get
1195 to the bottom of them.
1196

1200
1201 2012-04-27 Eli Zaretskii <eliz@gnu.org>
1202
1203 * xdisp.c (pos_visible_p): If the window start position is beyond
1204 ZV, start the display from buffer beginning. Prevents assertion
1205 violation in init_iterator when the minibuffer window is scrolled
1206 via the scroll bar.
1207
1208 * window.c (window_scroll_pixel_based): Likewise.
1209
1210 2012-04-27 Chong Yidong <cyd@gnu.org>
1211

1225
1226 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
1227 display element, check also the underlying string or buffer
1228 character. (Bug#11341)
1229

1231 (add_menu_item): If the call to AppendMenuW (via
1232 unicode_append_menu) fails, disable Unicode menus only if we are
1233 running on Windows 9X/Me.
1234
1235 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>

1238 (xgetint): Add missing shift for LSB tags.
1239
1240 2012-04-24 Martin Rudalics <rudalics@gmx.at>
1241
1242 * keyboard.c (read_char): Don't wipe echo area for select window
1243 events: These might get delayed via `mouse-autoselect-window'
1244 (Bug#11304).
1245
1246 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
1247

1256 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
1257
1258 Do not create empty overlays with the evaporate property (Bug#9642).
1259 * buffer.c (Fmove_overlay): Delete an evaporating overlay
1260 if it becomes empty after its bounds are adjusted to fit within
1261 its buffer. Without this fix, in a nonempty buffer (let ((o
1262 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
1263 yields an empty overlay that has the evaporate property, which is
1264 not supposed to happen.
1265
1266 Fix minor GTK3 problems found by static checking.
1267 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)

1526
1527 * nsterm.m (constrainFrameRect): Always constrain when there is only
1528 one screen (Bug#10962).

1537
1538 2012-04-11 Daniel Colascione <dancol@dancol.org>
1539
1540 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
1541 against is gone. It's better to use vfork now so that when Cygwin
1542 gains a new, working vfork, we use it automatically (bug#10398).
1543
1544 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
1545
1546 * window.c (save_window_save): Obey window-point-insertion-type.
1547
1548 2012-04-11 Glenn Morris <rgm@gnu.org>
1549

1557
1558 * keyboard.c: Override inhibit-quit after the third C-g (bug#6585).
1559 (force_quit_count): New var.
1560 (handle_interrupt): Use it.
1561
1562 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
1563
1564 * w32.c (w32_delayed_load): Record the full path of the library
1565 being loaded (bug#10424).
1566
1567 2012-04-09 Glenn Morris <rgm@gnu.org>
1568
1569 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
1570 not just in the obarray, before snarfing them. (Bug#11036)
1571
1572 * Makefile.in ($(leimdir)/leim-list.el):
1573 Pass EMACS rather than BUILT_EMACS.
1574
1575 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
1576
1577 * process.c (make_process):
1578 * process.h: Add integer `gnutls_handshakes_tried' member to
1579 process struct.
1580
1581 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
1582 Add convenience `GNUTLS_LOG2i' macro.
1583
1584 * gnutls.c (gnutls_log_function2i): Convenience log function.
1585 (emacs_gnutls_read): Use new log functions,
1586 `gnutls_handshakes_tried' process member, and
1587 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
1588 attempts per process (connection).
1589
1590 2012-04-09 Chong Yidong <cyd@gnu.org>
1591
1592 * eval.c (Fuser_variable_p, user_variable_p_eh)
1593 (lisp_indirect_variable): Functions deleted.
1594 (Fdefvar): Caller changed.
1595

1598
1599 2012-04-09 Eli Zaretskii <eliz@gnu.org>
1600
1601 * xdisp.c (set_cursor_from_row): If the display string appears in
1602 the buffer at position that is closer to point than the position
1603 after the display string, display the cursor on the first glyph of
1604 the display string. Fixes cursor display when a 'display' text
1605 property immediately follows invisible text. (Bug#11094)
1606
1607 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
1608
1609 composite.c: use 'double' consistently
1610 * composite.c (get_composition_id): Use 'double' consistently
1611 instead of converting 'float' to 'double' and vice versa; this is
1612 easier to understand and avoids a GCC warning.
1613
1614 2012-04-09 Glenn Morris <rgm@gnu.org>
1615
1616 * Makefile.in: Generate leim-list with bootstrap-emacs, in
1617 preparation for dumping it with emacs. (Bug#4789)
1618 (leimdir): New variable.
1619 ($(leimdir)/leim-list.el): New rule.
1620 (emacs$(EXEEXT)): Depend on leim-list.el.

1625
1626 2012-04-08 Andreas Schwab <schwab@linux-m68k.org>
1627
1628 * lisp.h (struct Lisp_Symbol): Add explicit padding to ensure
1629 proper alignment.
1630
1631 2012-04-07 Juanma Barranquero <lekktu@gmail.com>

1636 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
1637
1638 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
1639 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
1640 (mark_memory): Mark Lisp_Objects only if pointers might hide in
1641 objects, as mark_maybe_pointer will catch them otherwise.
1642 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
1643 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
1644
1645 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
1646
1647 Fix typo that broke non-Windows builds.
1648 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.
1649
1650 2012-04-07 Eli Zaretskii <eliz@gnu.org>
1651
1652 Support building on MS-Windows with libxml2.
1653
1654 * makefile.w32-in (OBJ2): Add xml.$(O).
1655 (GLOBAL_SOURCES): Add xml.c.

1657
1658 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.

1660 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
1661 [!WINDOWSNT]: New macros.
1662 (init_libxml2_functions, libxml2_loaded_p): New functions.
1663 (parse_region): Call fn_xmlCheckVersion instead of using the macro
1664 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
1665 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
1666 Calls xmlCleanupParser only if libxml2 was loaded (or statically
1667 linked in).
1668 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
1669 Call init_libxml2_functions before calling libxml2 functions.
1670 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
1671
1672 * emacs.c: Don't include libxml/parser.h.
1673 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
1674 xmlCleanupParser directly.
1675
1676 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
1677
1678 2012-04-07 Eli Zaretskii <eliz@gnu.org>
1679
1680 * indent.c (Fvertical_motion): If there is a display string at
1681 point, use it.vpos to compute how many lines to backtrack after
1682 move_it_to point. (Bug#11133)
1683
1684 2012-04-06 Eli Zaretskii <eliz@gnu.org>
1685
1686 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
1687 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
1688 about subtle differences between FETCH_CHAR* and STRING_CHAR*
1689 macros related to unification of CJK characters. For the details,
1690 see the discussion following the message here:
1691 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
1692
1693 2012-04-04 Chong Yidong <cyd@gnu.org>
1694
1695 * keyboard.c (Vdelayed_warnings_list): Doc fix.
1696
1697 2012-04-01 Eli Zaretskii <eliz@gnu.org>
1698
1699 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
1700 instead of alloca. (Bug#11138)
1701
1702 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
1703
1704 * w32menu.c (is_simple_dialog): Properly check lisp types.
1705 (Bug#11141)
1706
1707 2012-03-31 Eli Zaretskii <eliz@gnu.org>
1708
1709 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
1710 position we get to after a call to move_it_to fails the
1711 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
1712 only if we wind up in a string from display property. (Bug#11063)
1713
1714 * window.c (Fdelete_other_windows_internal): Invalidate the row
1715 and column information about mouse highlight, so that redisplay
1716 restores it after reallocating the glyph matrices. (Bug#7464)
1717
1718 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
1719 string comes from a `display' text property, use the buffer
1720 position of that property as if we actually saw that position in
1721 the row's glyphs.
1722 (move_it_by_lines): Remove the assertion that
1723 "it->current_x == 0 && it->hpos == 0" which can be legitimately
1724 violated when there's a before-string at the beginning of a line.
1725 (Bug#11063)
1726
1727 2012-03-30 Eli Zaretskii <eliz@gnu.org>
1728
1729 * xdisp.c (append_space_for_newline): If the default face was
1730 remapped, use the remapped face for the appended newline.
1731 (extend_face_to_end_of_line): Use the remapped default face for
1732 extending the face to the end of the line.
1733 (display_line): Call extend_face_to_end_of_line when the default
1734 face was remapped. (Bug#11068)
1735
1736 2012-03-29 Eli Zaretskii <eliz@gnu.org>
1737
1738 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
1739
1740 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
1741
1742 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
1743
1744 2012-03-27 Glenn Morris <rgm@gnu.org>
1745
1746 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
1747 Doc fixes.
1748
1749 2012-03-26 Kenichi Handa <handa@m17n.org>
1750
1751 * dispextern.h (struct glyph): Fix previous change. Change the
1752 bit length of glyphless.ch to 25 (Bug#11082).
1753
1754 2012-03-26 Chong Yidong <cyd@gnu.org>
1755
1756 * keyboard.c (Vselection_inhibit_update_commands): New variable.
1757 (command_loop_1): Use it; inhibit selection update for
1758 handle-select-window too (Bug#8996).
1759
1760 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
1761
1762 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
1763
1764 2012-03-25 Kenichi Handa <handa@m17n.org>
1765
1766 * dispextern.h (struct glyph): Change the bit length of
1767 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
1768
1769 2012-03-24 Eli Zaretskii <eliz@gnu.org>
1770
1771 * s/ms-w32.h (tzname): Include time.h before redirecting to
1772 _tzname. Fixes the MSVC build. (Bug#9960)
1773
1774 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
1775
1776 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
1777 characters.
1778
1779 * xterm.c (XTread_socket): Only modify handling_signal if
1780 !SYNC_INPUT. (Bug#11080)
1781
1782 2012-03-23 Eli Zaretskii <eliz@gnu.org>
1783
1784 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
1785 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
1786 when fetching a multibyte character consumes more bytes than
1787 CHAR_BYTES returns, due to unification of CJK characters in
1788 string_char. (Bug#11073)
1789
1790 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
1791
1792 * process.c (wait_reading_process_output): Handle pty disconnect
1793 by refraining from sending oneself a SIGCHLD (bug#10933).
1794
1795 2012-03-22 Chong Yidong <cyd@gnu.org>
1796
1797 * dispextern.h (struct it): New member string_from_prefix_prop_p.
1798
1799 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
1800 Mark string as coming from a prefix property.
1801 (handle_face_prop): Use default face for prefix strings (Bug#4281).
1802 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
1803
1804 2012-03-21 Chong Yidong <cyd@gnu.org>
1805
1806 * xfaces.c (Vface_remapping_alist): Doc fix.
1807
1808 2012-03-20 Eli Zaretskii <eliz@gnu.org>
1809
1810 * w32proc.c (Fw32_set_console_codepage)

1812 Doc fixes.
1813
1814 2012-03-20 Chong Yidong <cyd@gnu.org>
1815
1816 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
1817 to reflect default non-nil value of redisplay-dont-pause.
1818
1819 2012-03-19 Kenichi Handa <handa@m17n.org>
1820
1821 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
1822 it fit in a valid range (Bug#11003).
1823
1824 2012-03-18 Eli Zaretskii <eliz@gnu.org>
1825
1826 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
1827 that is not from display property, accept the row as a "cursor
1828 row" if one of the string's character has a non-nil `cursor'
1829 property. Fixes cursor positioning when there are newlines in
1830 overlay strings, e.g. in icomplete.el. (Bug#11035)
1831
1832 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
1833
1834 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
1835
1836 2012-03-12 Chong Yidong <cyd@gnu.org>
1837
1838 * eval.c (inhibit_lisp_code): Rename from
1839 inhibit_window_configuration_change_hook; move from window.c.
1840
1841 * xfns.c (unwind_create_frame_1, Fx_create_frame):
1842 * window.c (run_window_configuration_change_hook)
1843 (syms_of_window): Callers changed.
1844
1845 2012-03-11 Chong Yidong <cyd@gnu.org>
1846
1847 * keymap.c (Fkey_description): Doc fix (Bug#9700).
1848
1849 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
1850
1851 2012-03-10 Chong Yidong <cyd@gnu.org>
1852
1853 * frame.c (other_visible_frames): Don't assume the selected frame
1854 is visible (Bug#10955).

1857
1858 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
1859
1860 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
1861
1862 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
1863 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
1864 zero (Bug#10954).
1865
1866 2012-03-03 Glenn Morris <rgm@gnu.org>
1867
1868 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
1869
1870 2012-03-02 Eli Zaretskii <eliz@gnu.org>
1871
1872 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
1873 position past the first glyph_row that ends at ZV. (Bug#10902)
1874 (redisplay_window, next_element_from_string): Fix typos in
1875 comments.
1876 (redisplay_window): Pass to move_it_vertically the margin in
1877 pixels, not in screen lines.
1878
1879 2012-03-02 Glenn Morris <rgm@gnu.org>
1880
1881 * buffer.c (buffer-list-update-hook): Doc fix.
1882
1883 2012-02-29 Eli Zaretskii <eliz@gnu.org>
1884
1885 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
1886 push_it before setting up the iterator for the first overlay
1887 string, even if we have an empty string loaded.
1888 (next_overlay_string): If there's an empty string on the iterator
1889 stack, pop the stack. (Bug#10903)
1890
1891 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
1892
1893 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
1894 Suggested by Stefan Monnier in
1895 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
1896 * alloc.c (widen_to_Lisp_Object): New static function.
1897 (mark_memory): Also mark Lisp_Objects by fetching pointer words
1898 and widening them to Lisp_Objects. This would work even if
1899 USE_LSB_TAG is defined and wide integers are used, which might
1900 happen in a future version of Emacs.
1901
1902 2012-02-25 Chong Yidong <cyd@gnu.org>
1903
1904 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):

1909 before saving to clipboard manager.
1910
1911 2012-02-24 Chong Yidong <cyd@gnu.org>
1912
1913 * keyboard.c (process_special_events): Handle all X selection
1914 requests in kbd_buffer, not just the next one (Bug#8869).
1915
1916 2012-02-23 Chong Yidong <cyd@gnu.org>
1917
1918 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
1919 call when setting menu-bar-lines and tool-bar-lines parameters.
1920 (unwind_create_frame_1): New helper function.
1921
1922 * window.c (inhibit_window_configuration_change_hook): New var.
1923 (run_window_configuration_change_hook): Obey it.
1924 (syms_of_window): Initialize it.
1925
1926 2012-02-22 Chong Yidong <cyd@gnu.org>
1927
1928 * xterm.c (x_draw_image_relief): Add missing type check for
1929 Vtool_bar_button_margin (Bug#10743).
1930

1932
1933 * fileio.c (Vfile_name_handler_alist): Doc fix.
1934
1935 * buffer.c (Fget_file_buffer): Protect against invalid file
1936 handler return value.
1937
1938 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
1939
1940 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
1941 when computing $valmask.
1942
1943 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
1944 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
1945 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
1946 It's useless in that case, and it can cause problems on hosts
1947 that allocate halves of EMACS_INT values separately.

2583
2584 2011-11-29 Jan Djärv <jan.h.d@swipnet.se>

2733 Otherwise, valgrind does not work on some platforms.
2734 Problem reported by Andreas Schwab in
2735 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
2736 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
2737 is set, removing the need for VIRT_ADDRESS_VARIES.
2738 (PURE_P): Use a more-efficient implementation that needs just one
2739 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
2740 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
2741 to 4 (xorl, subq, cmpq, setbe).
2742 * alloc.c (pure): Always extern now, since that's the
2743 VIRT_ADDR_VARIES behavior.
2744 (PURE_POINTER_P): Use a single comparison, not two, for
2745 consistency with the new puresize.h.
2746 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
2747 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

2753 (erase_phys_cursor, update_window_cursor, show_mouse_face)
2754 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
2755 behave as if the cursor position were at the window margin.
2756
2757 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
2758 and the cursor position is out of bounds, behave as if the cursor
2759 position were at the window margin. (Bug#10075)
2760
2761 2011-11-18 Chong Yidong <cyd@gnu.org>
2762
2763 * window.c (Fwindow_combination_limit): Make first argument
2764 non-optional, since it is meaningless for live windows like the
2765 selected window.

2779 hash values of the two rows.
2780 (copy_row_except_pointers): Preserve the used[] arrays and the
2781 hash values of the two rows. (Bug#10035)
2782 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
2783
2784 * xdisp.c (row_hash): New function, body extracted from
2785 compute_line_metrics.
2786 (compute_line_metrics): Call row_hash, instead of computing the
2787 hash code inline.
2788
2789 * dispnew.c (verify_row_hash): Call row_hash for computing the
2790 hash code of a row, instead of duplicating code from xdisp.c.
2791

2831
2832 * xdisp.c (display_line): Move the call to
2833 highlight_trailing_whitespace before the call to
2834 compute_line_metrics, since the latter needs to see the final
2835 faces of all the glyphs to compute ROW's hash value.
2836 Fixes assertion violations in row_equal_p. (Bug#10035)
2837
2838 2011-11-14 Juanma Barranquero <lekktu@gmail.com>

2902 et seq.
2903 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

2931
2932 * w32.c (check_windows_init_file): Don't look for term/w32-win.el

2977 (window_box_width, window_box_left, window_box_left_offset)
2978 (window_box_right, window_box_right_offset): Declare extern.
2979 Otherwise, these inline functions do not conform to C99 and
2980 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
2981 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
2982 * intervals.c (adjust_intervals_for_insertion)

2985 (static_offset_intervals): Remove.
2986 (offset_intervals): Rewrite using the old contents of
2987 static_offset_intervals. The old version didn't conform to C99
2988 because an extern inline function contained a reference to an
2989 identifier with static linkage.

3011 (Fwindow_vscroll): Doc fix.

3222 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
3223 New functions.
3224 (w32font_open_internal, compute_metrics):
3225 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
3226 instead of calling the "wide" APIs directly.
3227
3228 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
3229
3230 * w32.h (syms_of_w32font): Add prototype.

3239 2011-10-27 Chong Yidong <cyd@gnu.org>
3240
3241 * process.c (make_process): Set gnutls_state to NULL.
3242
3243 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
3244 non-NULL, regardless of GNUTLS_INITSTAGE.
3245 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
3246 an error. Set process slots as soon as we allocate them.
3247
3248 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
3249
3250 2011-10-27 Chong Yidong <cyd@gnu.org>
3251
3252 * gnutls.c (emacs_gnutls_deinit): New function.
3253 Deallocate credentials structures as well as calling gnutls_deinit.

3271
3272 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
3273
3274 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).

3289
3290 * bidi.c (bidi_line_init): Initialize the next_en_type member.
3291 (bidi_resolve_explicit_1): When next_en_pos is valid for the
3292 current character, check also for next_en_type being WEAK_EN.
3293 (bidi_resolve_weak): Don't enter the expensive loop if the current
3294 position is before next_en_pos. Record the bidi type of the first
3295 non-ET, non-BN character we find, in addition to its position.
3296 (bidi_level_of_next_char): Invalidate next_en_type when
3297 next_en_pos is over-stepped.
3298
3299 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
3300
3301 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
3302 * editfns.c: Rewrite current-time-zone so that it invokes
3303 the equivalent of (format-time-string "%Z") to get the time zone name.
3304 This fixes a bug when the time zone name contains characters that
3305 need converting from the system time locale to Emacs internal format.
3306 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
3307 that patch fixed format-time-string to do the conversion, but
3308 I forgot to fix current-time-zone.
3309 (format_time_string): New function, containing most of
3310 what Fformat_time_string used to contain.
3311 (Fformat_time_string): Rewrite in terms of format_time_string.
3312 This doesn't change this function's behavior.
3313 (current-time-zone): Rewrite to use format_time_string.
3314 This fixes the bug reported by Michael Schierl in
3315 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
3316 Jason Rumney's 2007-06-07 change worked around this bug, but
3317 didn't fix it.
3318 * systime.h (tzname, timezone): Remove no-longer-used declarations.
3319
3320 2011-10-19 Eli Zaretskii <eliz@gnu.org>
3321
3322 * xdisp.c (start_display): If the character at POS is displayed
3323 via a display vector, reset IT->current.dpvec_index to zero.
3324 (try_window_reusing_current_matrix): If a line ends in a display
3325 vector or the next line starts in a display vector, continue
3326 redrawing the window even though the character position of
3327 start_row was reached.
3328 (Bug#9771, part 2)
3329
3330 2011-10-18 Chong Yidong <cyd@gnu.org>
3331
3332 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
3333 with nobreak-char-display too.
3334
3335 2011-10-18 Eli Zaretskii <eliz@gnu.org>
3336
3337 Fix part 3 of bug#9771.
3338 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
3339 (bidi_resolve_neutral): Don't enter the expensive loop looking for
3340 non-neutral characters if the current character is a paragraph
3341 separator (a.k.a. Newline). This avoids running the same
3342 expensive loop twice, once when we consume the preceding newline
3343 and the other time when the line actually needs to be displayed.
3344 Avoid the loop when we see neutrals on the base embedding level
3345 following a character whose directionality is the same as the
3346 paragraph's. This avoids running the expensive loop when a line
3347 ends in a long sequence of neutrals, like control characters.
3348 Add assertion against STRONG_AL type. Slightly rearrange code
3349 that determines the type of a neutral given the first non-neutral
3350 that follows it.
3351 (bidi_level_of_next_char): Set next_en_pos to zero when
3352 invalidating its info.
3353
3354 2011-10-17 Eli Zaretskii <eliz@gnu.org>
3355
3356 * xdisp.c (push_display_prop): Determine whether to record string
3357 or buffer position by IT->string, not by IT->method. Allow
3358 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
3359 (move_it_vertically_backward): Don't look for character position
3360 immediately after the newline when in a continuation line.
3361 (Bug#9771, part 1)
3362
3363 2011-10-15 Martin Rudalics <rudalics@gmx.at>

3366 vertical border check. (Bug#5357) (Bug#9618)
3367
3368 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
3369
3370 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
3371 errors in XSetWindowBorder (bug#9310).
3372
3373 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
3374
3375 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
3376 avoid crash when xmalloc overrun checking is enabled.
3377
3378 2011-10-13 Eli Zaretskii <eliz@gnu.org>
3379
3380 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
3381 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
3382 cursor motion with <left> and <right> arrow keys.
3383
3384 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
3385 some callers set that themselves.
3386
3387 2011-10-12 Eli Zaretskii <eliz@gnu.org>
3388
3389 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
3390 display string and the previous row comes from the same string and
3391 is empty. (Bug#9739) (Bug#9738)
3392
3393 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
3394

3396
3397 2011-10-12 Eli Zaretskii <eliz@gnu.org>
3398
3399 * bidi.c (bidi_level_of_next_char):
3400 * xdisp.c (get_visually_first_element): Remove old incorrect
3401 comments regarding the Unicode Line Separator character.
3402
3403 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
3404
3405 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
3406
3407 * alloc.c (Fgc_status): Do not access beyond zombies array
3408 boundary if nzombies > MAX_ZOMBIES.
3409 * alloc.c (dump_zombies): Add missing format specifier.
3410
3411 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
3412
3413 * xdisp.c (set_cursor_from_row): Simplify conditionals,
3414 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
3415
3416 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
3417 Some packages use them to denote characters with modifiers.
3418
3419 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
3420
3421 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
3422 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
3423 matching a pp-number. Rename parameter var to var1.
3424
3425 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
3426
3427 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
3428
3429 2011-10-08 Glenn Morris <rgm@gnu.org>
3430
3431 * callint.c (Fcall_interactively): Give a more explicit error for the
3432 'c' case with a non-character input. (Bug#8479)
3433
3434 2011-10-08 Eli Zaretskii <eliz@gnu.org>
3435
3436 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
3437 lines.
3438 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
3439 lines that are hscrolled on the left.
3440
3441 * dispnew.c (buffer_posn_from_coords): Account for a possible
3442 presence of header-line. (Bug#4426)
3443
3444 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
3445
3446 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
3447 Don't advertise functionality which we discourage or doesn't work.
3448
3449 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
3450
3451 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
3452 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
3453 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
3454 this makes Emacs dump core during garbage collection on rare
3455 occasions. sizeof is obviously inferior to offsetof here, so
3456 stick with offsetof.
3457 (GC_POINTER_ALIGNMENT): New macro.
3458 (mark_memory): Omit 3rd (offset) arg; caller changed.
3459 Don't assume EMACS_INT alignment is the same as pointer alignment.
3460
3461 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
3462
3463 * keyboard.c (read_key_sequence_remapped): New var.
3464 (read_key_sequence): Compute remapping in the right buffer.
3465 (command_loop_1): Use read_key_sequence's remapping directly.
3466
3467 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
3468
3469 * dired.c (file_name_completion): Don't expand file name.
3470 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
3471 before checking file name handler.
3472
3473 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
3474 they've been requested explicitly (bug#9591).
3475
3476 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
3477
3478 * keymap.c (Fsingle_key_description): Use make_specified_string
3479 instead of build_string to build string from push_key_description.
3480 (Bug#5193)
3481
3482 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
3483
3484 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
3485 This fixes a Y2038 bug on 64-bit hosts.
3486 * buffer.c (reset_buffer):
3487 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
3488 (Fclear_buffer_auto_save_failure):
3489 Use 0, not -1, to represent an unset failure time, since time_t
3490 might not be signed.
3491
3492 Remove dependency on glibc malloc internals.
3493 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
3494 Move back here from lisp.h, but with their new implementations.
3495 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
3496 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
3497 * charset.c (charset_table_init): New static var.
3498 (syms_of_charset): Use it instead of xmalloc. This removes a
3499 dependency on glibc malloc internals. See Eli Zaretskii's comment in
3500 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
3501 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
3502 Move back to alloc.c.
3503 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
3504 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
3505
3506 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
3507
3508 * nsterm.m (windowDidResize): Call x_set_window_size only when
3509 ns_in_resize is true. Otherwise set pixelwidth/height and
3510 call change_frame_size (Bug#9628).
3511
3512 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
3513
3514 Port --enable-checking=all to Fedora 14 x86-64.
3515 * charset.c (syms_of_charset): Also account for glibc malloc's
3516 internal overhead when calculating the initial malloc maximum.
3517
3518 Port --enable-checking=all to Fedora 14 x86.
3519 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
3520 Move to lisp.h.
3521 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
3522 (overrun_check_realloc, overrun_check_free):
3523 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
3524 That way, xmalloc returns a properly-aligned pointer even if
3525 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
3526 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
3527 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
3528 into account when calculating the initial malloc maximum.
3529 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
3530 Move here from alloc.c, so that charset.c can use it too.
3531 Properly align; the old code wasn't right for common 32-bit hosts
3532 when configured with --enable-checking=all.
3533 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
3534 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
3535
3536 2011-09-29 Eli Zaretskii <eliz@gnu.org>
3537
3538 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
3539 use EDOM.
3540
3541 2011-09-28 Eli Zaretskii <eliz@gnu.org>
3542
3543 * xdisp.c (compute_display_string_end): If there's no display
3544 string at CHARPOS, return -1.
3545
3546 * bidi.c (bidi_fetch_char): When compute_display_string_end
3547 returns a negative value, treat the character as a normal
3548 character not covered by a display string. (Bug#9624)
3549
3550 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
3551
3552 * lread.c (Fread_from_string): Fix typo in docstring.
3553
3554 2011-09-27 Eli Zaretskii <eliz@gnu.org>
3555
3556 * xdisp.c (handle_invisible_prop): If invisible text ends on a
3557 newline, reseat the iterator instead of bidi-iterating there one
3558 character at a time. (Bug#9610)
3559 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
3560 TO_CHARPOS if the bidi iterator is at base embedding level.
3561
3562 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
3563
3564 * lread.c (readevalloop): Use correct code for NBSP.
3565 (read1): Likewise. (Bug#9608)
3566
3567 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
3568
3569 * dbusbind.c (Fdbus_register_signal): When service is not
3570 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
3571
3572 2011-09-25 Glenn Morris <rgm@gnu.org>
3573

3579 (Fset_window_next_buffers): Doc fix.
3580
3581 2011-09-24 Glenn Morris <rgm@gnu.org>
3582
3583 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
3584
3585 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
3586
3587 Fix minor problems found by static checking.
3588 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.

3590
3591 2011-09-24 Eli Zaretskii <eliz@gnu.org>
3592
3593 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
3594 Default value is now t. Doc fix.
3595
3596 * indent.c (Fvertical_motion): Compute and apply the overshoot
3597 logic when moving up, not only when moving down. Fix the
3598 confusing name and values of the it_overshoot_expected variable;
3599 logic changes accordingly. (Bug#9254) (Bug#9549)
3600
3601 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
3602 CHARPOS is covered by a display string which includes newlines.
3603 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
3604 is covered by a display string with embedded newlines.
3605
3606 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
3607
3608 * dbusbind.c (Fdbus_register_signal): Add match rule to
3609 Vdbus_registered_objects_table. (Bug#9581)
3610 (Fdbus_register_method, Vdbus_registered_objects_table):
3611 Fix docstring.
3612
3613 2011-09-24 Jim Meyering <meyering@redhat.com>
3614
3615 do not ignore write error for any output size
3616 The previous change was incomplete.
3617 While it makes emacs --batch detect the vast majority of stdout
3618 write failures, errors were still ignored whenever the output size is
3619 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
3620 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \

3626 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
3627
3628 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
3629
3630 * emacs.c (Fkill_emacs): In noninteractive mode exit
3631 non-successfully if a write error occurred on stdout. (Bug#9574)
3632
3633 2011-09-21 Eli Zaretskii <eliz@gnu.org>
3634
3635 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
3636 the xassert test.
3637
3638 * dispextern.h (struct it): Update the comment documenting what
3639 can it->OBJECT be.
3640
3641 2011-09-20 Eli Zaretskii <eliz@gnu.org>
3642
3643 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
3644 a display string, extend search for cursor position to end of row.
3645 (find_row_edges): If the row ends in a newline from a display
3646 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
3647 Handle the case of a display string with multiple newlines.
3648 (Fcurrent_bidi_paragraph_direction): Fix search for previous
3649 non-empty line. Fixes confusing cursor motion with arrow keys at
3650 the beginning of a line that starts with whitespace.

3652 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
3653
3654 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
3655 (bug#9493).

3663
3664 * xdisp.c (display_line): Record maximum and minimum buffer
3665 positions even if no glyphs were produced (e.g., by a zero-width
3666 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
3667 buffer positions that will be removed from the glyph row because
3668 they don't fit.
3669 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
3670 column is beyond frame width: don't subtract 1 "pixel" when
3671 computing width of the stretch.
3672 (reseat_at_next_visible_line_start): Undo the change made on
3673 2011-09-17 that saved paragraph information and restored it after
3674 the call to `reseat'. (Bug#9545)
3675
3676 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
3677
3678 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
3679 and turn window cursor on if cleared (Bug#9415).
3680
3681 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
3682
3683 * search.c (boyer_moore): Take unibyte characters from pattern
3684 literally. (Bug#9458)
3685
3686 2011-09-18 Eli Zaretskii <eliz@gnu.org>
3687

3690 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
3691
3692 Fix minor problem found by static checking.
3693 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
3694 initialized, to pacify gcc -Wuninitialized.
3695
3696 * fileio.c: Report proper errno when syscall falls.
3697 (Finsert_file_contents): Save and restore errno,
3698 so that report_file_error outputs the correct diagnostic.
3699 (Fwrite_region) [CLASH_DETECTION]: Likewise.
3700
3701 2011-09-18 Eli Zaretskii <eliz@gnu.org>

3704
3705 2011-09-17 Eli Zaretskii <eliz@gnu.org>
3706
3707 * xdisp.c (produce_stretch_glyph): Another fix for changes made on

3709
3710 2011-09-17 Eli Zaretskii <eliz@gnu.org>
3711
3712 * xdisp.c (reseat_at_next_visible_line_start): Keep information
3713 about the current paragraph and restore it after the call to reseat.
3714
3715 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
3716 (bidi_find_paragraph_start): Search back for paragraph beginning
3717 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
3718 (bidi_move_to_visually_next): Only trigger paragraph-related
3719 computations when the last character is a newline or at EOB, not
3720 just any NEUTRAL_B. (Bug#9470)
3721
3722 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
3723 truncated lines if point is covered by a display string. (Bug#9524)
3724
3725 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
3726
3727 * xselect.c: Relax test for outgoing X longs (Bug#9498).
3728 (cons_to_x_long): New function.
3729 (lisp_data_to_selection_data): Use it. Correct the test for
3730 short-versus-long data; it was negated. Break out of vector
3731 loop, for efficiency, when a long datum is discovered.
3732
3733 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
3734
3735 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
3736
3737 2011-09-16 Eli Zaretskii <eliz@gnu.org>
3738
3739 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
3740 GCC PR/17406) by declaring this function with external scope.
3741
3742 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
3743
3744 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
3745 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
3746
3747 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
3748

3762
3763 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
3764 This occurs when processing a multibyte format.
3765 Problem reported by Wolfgang Jenker.
3766
3767 2011-09-15 Johan Bockgård <bojohan@gnu.org>
3768
3769 * xdisp.c (try_cursor_movement): Only check for exact match if
3770 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
3771
3772 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
3773
3774 Remove unused external symbols.

3781
3782 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
3783
3784 * xselect.c: Use signed conversions more consistently (Bug#9498).
3785 (selection_data_to_lisp_data): Assume incoming selection data are
3786 signed integers, not unsigned. This is to be consistent with
3787 outgoing selection data, which was modified to use signed integers
3788 in as part of the fix to Bug#9196 in response to Jan D.'s comment
3789 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
3790 expects long, not unsigned long.
3791
3792 2011-09-14 Eli Zaretskii <eliz@gnu.org>
3793
3794 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
3795 computation of loop end. Reported by Johan Bockgård
3796 <bojohan@gnu.org>.
3797
3798 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
3799
3800 * frame.c (Fother_visible_frames_p): Function deleted.
3801
3802 2011-09-12 Eli Zaretskii <eliz@gnu.org>
3803
3804 * indent.c (compute_motion): Process display vector front to back
3805 rather than the other way around. (Bug#2496)
3806
3807 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
3808
3809 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
3810
3811 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
3812
3813 * minibuf.c (Fread_from_minibuffer): Doc fix.
3814
3815 2011-09-11 Eli Zaretskii <eliz@gnu.org>
3816
3817 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
3818 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
3819
3820 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
3821
3822 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
3823 value for non-existent files.
3824
3825 2011-09-11 Eli Zaretskii <eliz@gnu.org>
3826
3827 * fileio.c (Finsert_file_contents): If the file cannot be opened,
3828 set its "size" to -1. This will set the modtime_size field of
3829 the corresponding buffer to -1, which is what
3830 verify-visited-file-modtime expects for files that do not exist.
3831 (Bug#9139)
3832
3833 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
3834
3835 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
3836 here ...
3837 * lisp.h: ... from here. push_key_description is no longer
3838 defined in keyboard.c, so its declaration should not be in
3839 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
3840 logically belongs with push_key_description.
3841
3842 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
3843
3844 * buffer.h: Include <sys/types.h> instead of <time.h>.
3845 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
3846 Problem reported by Herbert J. Skuhra.
3847
3848 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
3849
3850 * xml.c (parse_region): Make the parsing work for
3851 non-comment-starting XML files again (bug#9144).
3852
3853 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>

3857
3858 2011-09-10 Eli Zaretskii <eliz@gnu.org>
3859
3860 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
3861 redisplay in small windows.
3862
3863 2011-09-09 Eli Zaretskii <eliz@gnu.org>
3864
3865 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
3866
3867 2011-09-08 Martin Rudalics <rudalics@gmx.at>
3868
3869 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
3870 Operate on live windows only.
3871
3872 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
3873
3874 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
3875
3876 2011-09-07 Eli Zaretskii <eliz@gnu.org>
3877
3878 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
3879 only under bidi iteration.
3880
3881 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
3882
3883 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
3884
3885 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
3886
3887 isnan: Fix porting problem to Solaris 10 with bundled gcc.
3888 Without this fix, the command to link temacs failed due to an
3889 undefined symbol __builtin_isnan. This is because
3890 /usr/include/iso/math_c99.h #defines isnan(x) to
3891 __builtin_isnan(x), but the bundled gcc, which identifies itself
3892 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
3893 a __builtin_isnan.
3894 * floatfns.c (isnan): #undef, and then #define to a clone of
3895 what's in data.c.
3896 (Fisnan): Always define, since it's always available now.
3897 (syms_of_floatfns): Always define isnan at the Lisp level.
3898
3899 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
3900
3901 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
3902
3903 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
3904
3905 * fileio.c: Fix bugs with large file offsets (Bug#9428).
3906 The previous code assumed that file offsets (off_t values) fit in
3907 EMACS_INT variables, which is not true on typical 32-bit hosts.
3908 The code messed up by falsely reporting buffer overflow in cases
3909 such as (insert-file-contents "big" nil 1 2) into an empty buffer
3910 when "big" contains more than 2**29 bytes, even though this
3911 inserts just one byte and does not overflow the buffer.
3912 (Finsert_file_contents): Store file offsets as off_t
3913 values, not as EMACS_INT values. Check for overflow when
3914 converting between EMACS_INT and off_t. When checking for
3915 buffer overflow or for overlap, take the offsets into account.
3916 Don't use EMACS_INT for small values where int suffices.
3917 When checking for overlap, fix a typo: ZV was used where
3918 ZV_BYTE was intended.
3919 (Fwrite_region): Don't assume off_t fits into 'long'.
3920 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
3921
3922 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
3923
3924 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
3925
3926 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
3927
3928 sprintf-related integer and memory overflow issues (Bug#9412).
3929
3930 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
3931 (esprintf, exprintf, evxprintf): New functions.
3932 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
3933 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
3934 (modify_event_symbol): Do not assume that the length of
3935 name_alist_or_stem is safe to alloca and fits in int.
3936 (Fexecute_extended_command): Likewise for function name and binding.
3937 (Frecursion_depth): Wrap around reliably on integer overflow.
3938 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
3939 since some callers pass EMACS_INT values.
3940 (Fsingle_key_description): Don't crash if symbol name contains more
3941 than MAX_ALLOCA bytes.
3942 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
3943 (get_minibuffer): Arg is now EMACS_INT, not int.
3944 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
3945 (esprintf, exprintf, evxprintf): New decls.
3946 * window.h (command_loop_level, minibuf_level): Reflect API changes.
3947
3948 * dbusbind.c (signature_cat): New function.
3949 (xd_signature, Fdbus_register_signal):
3950 Do not overrun buffer; instead, report string overflow.
3951
3952 * dispnew.c (add_window_display_history): Don't overrun buffer.
3953 Truncate instead; this is OK since it's just a log.
3954
3955 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
3956 even if the time zone offset is outlandishly large.
3957 Don't mishandle offset == INT_MIN.
3958
3959 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
3960 when creating daemon; the previous buffer-overflow check was incorrect.
3961
3962 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
3963 which has the guts of the old verror function.
3964
3965 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
3966 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
3967
3968 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
3969 (font_unparse_xlfd): Don't blindly alloca long strings.
3970 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
3971 fits in int, when using sprintf. Use single snprintf to count
3972 length of string rather than counting it via multiple sprintfs;
3973 that's simpler and more reliable.
3974 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
3975 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
3976 sprintf, in case result does not fit in int.
3977
3978 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
3979 (fontset_from_font): Print it.
3980
3981 * frame.c (tty_frame_count): Now printmax_t, not int.
3982 (make_terminal_frame, set_term_frame_name): Print it.
3983 (x_report_frame_params): In X, window IDs are unsigned long,
3984 not signed long, so print them as unsigned.
3985 (validate_x_resource_name): Check for implausibly long names,
3986 and don't assume name length fits in 'int'.
3987 (x_get_resource_string): Don't blindly alloca invocation name;
3988 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
3989 not fit in int.
3990
3991 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
3992 (xg_check_special_colors, xg_set_geometry):
3993 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
3994
3995 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
3996 Use esprintf, not sprintf, in case result does not fit in int.
3997
3998 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
3999 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
4000 it as a large positive number.
4001 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
4002 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
4003
4004 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
4005 in case result does not fit in int.
4006
4007 * print.c (float_to_string): Detect width overflow more reliably.
4008 (print_object): Make sprintf buffer a bit bigger, to avoid potential
4009 buffer overrun. Don't assume list length fits in 'int'. Treat
4010 print length of 0 as 0, not as infinity; to be consistent with other
4011 uses of print length in this function. Don't overflow print length
4012 index. Don't assume hash table size fits in 'long', or that
4013 vectorlike size fits in 'unsigned long'.
4014
4015 * process.c (make_process): Use printmax_t, not int, to format
4016 process-name gensyms.
4017
4018 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
4019
4020 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
4021 to avoid potential buffer overrun.
4022
4023 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
4024 if X resource line is longer than 512 bytes.
4025
4026 * xfns.c (x_window): Make sprintf buffer a bit bigger
4027 to avoid potential buffer overrun.
4028
4029 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
4030
4031 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
4032
4033 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
4034
4035 Integer overflow fixes for scrolling, etc.
4036 Without these, Emacs silently mishandles large integers sometimes.
4037 For example, "C-u 4294967297 M-x recenter" was treated as if
4038 it were "C-u 1 M-x recenter" on a typical 64-bit host.
4039
4040 * xdisp.c (try_window_id): Check Emacs fixnum range before
4041 converting to 'int'.
4042
4043 * window.c (window_scroll_line_based, Frecenter):
4044 Check that an Emacs fixnum is in range before assigning it to 'int'.
4045 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
4046 values converted from Emacs fixnums.
4047 (Frecenter): Don't wrap around a line count if it is out of 'int'
4048 range; instead, treat it as an extreme value.
4049 (Fset_window_configuration, compare_window_configurations):
4050 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
4051
4052 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
4053 that can exceed INT_MAX. Check that EMACS_INT value is in range
4054 before assigning it to the (possibly-narrower) index.
4055 (match_limit): Don't assume that a fixnum can fit in 'int'.
4056
4057 * print.c (print_object): Use ptrdiff_t, not int, for index that can
4058 exceed INT_MAX.
4059
4060 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
4061 (Fvertical_motion): Don't wrap around LINES values that don't fit
4062 in 'int'. Instead, treat them as extreme values. This is good
4063 enough for windows, which can't have more than INT_MAX lines anyway.
4064
4065 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
4066
4067 * Require libxml/parser.h to avoid compilation warning.
4068
4069 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
4070
4071 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
4072 since this reportedly can destroy thread storage.
4073
4074 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
4075
4076 * syntax.c (find_defun_start): Update all cache variables if
4077 exiting early (Bug#9401).
4078
4079 2011-08-30 Eli Zaretskii <eliz@gnu.org>
4080
4081 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
4082
4083 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
4084 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
4085 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
4086
4087 * term.c (tty_append_glyph): New function.
4088 (produce_stretch_glyph): Static function and its prototype deleted.
4089
4090 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
4091 Add prototypes.
4092
4093 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
4094
4095 * image.c (parse_image_spec): Check for nonnegative, not for positive,
4096 when checking :margin (Bug#9390).
4097 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
4098 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
4099 so that the name doesn't mislead. All uses changed.
4100
4101 2011-08-28 Johan Bockgård <bojohan@gnu.org>
4102
4103 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
4104 set_tty_hooks.
4105
4106 2011-08-27 Eli Zaretskii <eliz@gnu.org>
4107
4108 * xdisp.c (move_it_to): Don't bail out early when reaching
4109 position beyond to_charpos, if we are scanning backwards.
4110 (move_it_vertically_backward): When DY == 0, make sure we get to
4111 the first character in the line after the newline.
4112
4113 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
4114
4115 * ccl.c: Improve and simplify overflow checking (Bug#9196).
4116 (ccl_driver): Do not generate an out-of-range pointer.
4117 (Fccl_execute_on_string): Remove unnecessary check for
4118 integer overflow, noted by Stefan Monnier in
4119 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
4120 Remove a FIXME that didn't need fixing.
4121 Simplify the newly-introduced buffer reallocation code.
4122
4123 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
4124
4125 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
4126
4127 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
4128
4129 Integer and memory overflow issues (Bug#9196).
4130
4131 * doc.c (get_doc_string): Rework so that
4132 get_doc_string_buffer_size is the actual buffer size, rather than
4133 being 1 less than the actual buffer size; this makes xpalloc more
4134 convenient.
4135
4136 * image.c (x_allocate_bitmap_record, cache_image):
4137 * xselect.c (Fx_register_dnd_atom):
4138 Simplify previous changes by using xpalloc.
4139
4140 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
4141 since either will do and ptrdiff_t is convenient with xpalloc.
4142
4143 * charset.c (charset_table_size)
4144 (struct charset_sort_data.priority): Now ptrdiff_t.
4145 (charset_compare): Don't overflow if priorities differ greatly.
4146 (Fsort_charsets): Don't assume list length fits in int.
4147 Check for size-calculation overflow when allocating sort data.
4148 (syms_of_charset): Allocate an initial charset table that is
4149 just under 64 KiB, to avoid problems with glibc malloc and mmap.
4150
4151 * cmds.c (internal_self_insert): Check for size-calculation overflow.
4152
4153 * composite.h (struct composition.glyph_len): Now int, not unsigned.
4154 The actual value is always <= INT_MAX, and leaving it unsigned made
4155 overflow checking harder.
4156
4157 * dispextern.h (struct glyph_matrix.rows_allocated)
4158 (struct face_cache.size): Now ptrdiff_t, for convenience in use
4159 with xpalloc. The values are still always <= INT_MAX.
4160
4161 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
4162
4163 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
4164 (SAFE_NALLOCA): New macro.
4165
4166 * region-cache.c (struct boundary.pos, find_cache_boundary)

4168 (set_cache_region, invalidate_region_cache)
4169 (revalidate_region_cache, know_region_cache, region_cache_forward)
4170 (region_cache_backward, pp_cache):
4171 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
4172 so that ptrdiff_t * can be passed to xpalloc.
4173 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
4174 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
4175 (pp_cache): Don't assume cache_len fits in int.
4176 * region-cache.h: Adjust extern decls to match.
4177
4178 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
4179 EMACS_INT, since either will do, for xpalloc.
4180
4181 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
4182 (xnmalloc, xnrealloc, xpalloc): New functions.
4183
4184 * bidi.c (bidi_shelve_header_size): New constant.
4185 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
4186 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
4187
4188 * bidi.c (bidi_cache_shrink):
4189 * buffer.c (overlays_at, overlays_in, record_overlay_string)
4190 (overlay_strings):
4191 Don't update size of array until after memory allocation succeeds,
4192 because xmalloc/xrealloc may not return.
4193 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
4194 now that we have proper integer overflow checking.
4195 (record_overlay_string, overlay_strings): Catch overflows when
4196 calculating size of overlay_str_buf.
4197
4198 * callproc.c (Fcall_process): Check for size overflow when
4199 calculating size of args2.
4200 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
4201 Normally we prefer signed values, but sticking with ptrdiff_t would
4202 require adding more-complicated checks.
4203
4204 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
4205 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
4206 Redo buffer-overflow calculations to avoid integer overflow.
4207 Add a FIXME comment where memory seems to be over-allocated.
4208
4209 * character.c (Fstring): Check for size-calculation overflow.
4210
4211 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
4212 unnecessary integer overflow. Check for size overflow.
4213 (encode_coding_object): Don't update size until xmalloc succeeds.
4214
4215 * composite.c (get_composition_id): Check for overflow in glyph
4216 length calculations.
4217

4220 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
4221 (scrolling_window): Check for overflow in size calculations.
4222 (line_draw_cost, realloc_glyph_pool, add_row_entry):
4223 Don't assume glyph table len fits in int.

4225 (row_table_size): Now ptrdiff_t, not int.
4226 (scrolling_window): Avoid overflow in size calculations.
4227 Don't update size until allocation succeeds.
4228 * fns.c (concat): Check for overflow in size calculations.

4237 EMACS_INT, where ptrdiff_t will do.
4238 (Fsubstitute_command_keys): Check for string overflow.
4239
4240 * editfns.c (set_time_zone_rule): Don't assume environment length
4241 fits in int.
4242 (message_length): Now ptrdiff_t, not int.
4243 (Fmessage_box): Don't update size until allocation succeeds.
4244 Don't assume message length fits in int.
4245 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
4246
4247 * emacs.c (main): Do not reallocate argv, since there is a null at
4248 the end that can be overwritten, and this way there's no need to
4249 worry about size-calculation overflow.
4250 (sort_args): Check for size-calculation overflow.
4251
4252 * eval.c (init_eval_once, grow_specpdl): Don't update size until
4253 alloc succeeds.
4254 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
4255
4256 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
4257 (x_set_scroll_bar_width, x_figure_window_size):
4258 Check for integer overflow.
4259 (x_set_alpha): Do not assume XINT fits in int.
4260
4261 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
4262 This is for the members text_lines, text_cols, total_lines, total_cols,
4263 where the system imposes an 'int' limit.
4264
4265 * fringe.c (Fdefine_fringe_bitmap):
4266 Don't update size until alloc works.
4267
4268 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
4269 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
4270
4271 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
4272 Check for size-calculation overflow.
4273 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
4274 do, as we prefer signed integers.
4275 (id_to_widget.max_size, id_to_widget.used)
4276 (xg_store_widget_in_map, xg_remove_widget_from_map)
4277 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
4278 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
4279 Use and return ptrdiff_t, not int.
4280 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
4281 * gtkutil.h: Change prototypes to match the above.
4282
4283 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
4284 are duplicate now that they've been promoted to lisp.h.
4285 (x_allocate_bitmap_record, x_alloc_image_color)
4286 (make_image_cache, cache_image, xpm_load):
4287 Don't update size until alloc is done.
4288 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
4289 (x_detect_edges):
4290 Check for size calculation overflow.
4291 (ct_colors_allocated_max): New constant.
4292 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
4293 overflow.

4296 (read_char_x_menu_prompt, read_char_minibuf_menu_width)
4297 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
4298 Use ptrdiff_t, not int, to count maps.
4299 (read_char_minibuf_menu_prompt): Check for overflow in size
4300 calculations. Don't update size until allocation succeeds.
4301 Redo calculations to avoid overflow.
4302 * keyboard.h: Change prototypes to match the above.
4303
4304 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
4305 to count maps.
4306 (current_minor_maps): Check for size calculation overflow.
4307 * keymap.h: Change prototypes to match the above.
4308

4329
4330 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
4331 for command line length. Do not attempt to address one before the
4332 beginning of an array, as that's not portable.
4333
4334 * term.c (max_frame_lines): Remove; unused.
4335 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
4336 not int.
4337 (encode_terminal_code, calculate_costs): Check for size
4338 calculation overflow.

4343
4344 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
4345 subtracting pointers.
4346 (gobble_line): Check for overflow more carefully. Don't update size
4347 until alloc done.
4348
4349 * tparam.c (tparam1): Use ptrdiff_t, not int, for sizes.
4350 Don't update size until alloc done.

4361 (Finternal_make_lisp_face, cache_face):
4362 Check for size calculation overflow.
4363 (cache_face): Treat size calculation overflows as if they were

4365
4366 * xfns.c (x_encode_text, x_set_name_internal)
4367 (Fx_change_window_property): Use ptrdiff_t, not int, to count

4372 (xg_select): Check for size calculation overflow.
4373 Don't update size until alloc done.
4374
4375 * xrdb.c (get_environ_db): Don't assume path length fits in int,
4376 as sprintf is limited to int lengths.
4377
4378 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
4379 (X_LONG_MIN): New macros.
4380 Use them to make the following changes clearer.
4381 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
4382 This change doesn't affect the value now, but it may help remind
4383 future maintainers not to raise the value too much later.
4384 (SELECTION_QUANTUM): Remove, replacing with ...
4385 (selection_quantum): ... new function, which avoids overflow.
4386 All uses changed.
4387 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
4388 assumption that selection length fits in 'int'.
4389 (x_reply_selection_request, x_handle_selection_request)
4390 (x_get_window_property, receive_incremental_selection)
4391 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
4392 (lisp_data_to_selection_data, clean_local_selection_data):
4393 Use ptrdiff_t, not int, to record length of selection.
4394 (x_reply_selection_request, x_get_window_property)
4395 (receive_incremental_selection, x_property_data_to_lisp):
4396 Redo calculations to avoid overflow.
4397 (x_reply_selection_request): When sending hint, ceiling it at
4398 X_LONG_MAX rather than relying on wraparound overflow to send
4399 something.
4400 (x_get_window_property, receive_incremental_selection)
4401 (lisp_data_to_selection_data, x_property_data_to_lisp):

4405 Don't store size until memory allocation succeeds.
4406 (x_get_window_property): Plug memory leak on memory exhaustion.
4407 Don't double-block input; malloc is safe here. Don't assume 2**34
4408 - 4 fits in unsigned long. Add an xassert to check
4409 XGetWindowProperty overflow. Be more careful about overflow
4410 calculations, and distinguish size from memory overflow better.
4411 (receive_incremental_selection): When tracing, don't assume
4412 unsigned int is less than INT_MAX.
4413 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
4414 harmful) conversions of unsigned short to int.
4415 (lisp_data_to_selection_data): Don't assume that integers
4416 in the range -65535 through -1 fit in an X unsigned short.
4417 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
4418 result parameters unless successful. Rely on cons_to_unsigned
4419 to report problems with elements; the old code wasn't right anyway.
4420 (x_check_property_data): Check for int overflow; we cannot use
4421 a wider type due to X limits.
4422 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
4423
4424 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.

4431 (x_term_init): Don't assume length fits in int (sprintf is limited
4432 to int size).
4433
4434 Use ptrdiff_t for composition IDs.

4453 * image.c (xpm_get_color_table_h):
4454 * lisp.h (hash_lookup, hash_put):
4455 * minibuf.c (Ftest_completion):
4456 Use ptrdiff_t for hash table indexes, not int (which is too
4457 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
4458 32-bit --with-wide-int hosts).
4459
4460 * charset.c (Fdefine_charset_internal): Check for integer overflow.
4461 Add a FIXME comment about memory leaks.
4462 (syms_of_charset): Don't assume xmalloc returns.
4463
4464 Don't assume that stated character widths fit in int.
4465 * character.c (Fchar_width, c_string_width, lisp_string_width):
4466 * character.h (CHAR_WIDTH):
4467 * indent.c (MULTIBYTE_BYTES_WIDTH):
4468 Use sanitize_char_width to avoid undefined and/or bad behavior
4469 with outlandish widths.
4470 * character.h (sanitize_tab_width): Rename from sanitize_width,
4471 now that we have two such functions. All uses changed.
4472 (sanitize_char_width): New inline function.
4473
4474 Don't assume that tab-width fits in int.
4475 * character.h (sanitize_width): New inline function.
4476 (SANE_TAB_WIDTH): New macro.
4477 (ASCII_CHAR_WIDTH): Use it.

4481
4482 * fileio.c: Integer overflow issues with file modes.
4483 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
4484
4485 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
4486 Remove unreachable code.
4487 (read_hex, load_charset_map_from_file): Check for integer overflow.
4488
4489 * xterm.c: Don't go over XClientMessageEvent limit.
4490 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
4491 (x_send_scroll_bar_event): Likewise. Check that the size does not
4492 exceed limits imposed by XClientMessageEvent, as well as the usual
4493 ptrdiff_t and size_t limits.
4494
4495 * keyboard.c: Overflow, signedness and related fixes.
4496 (make_lispy_movement): Use same integer type in forward decl
4497 that is used in the definition.
4498 (read_key_sequence, keyremap_step):
4499 Change bufsize argument back to int, undoing my 2011-03-30 change.
4500 We prefer signed types, and int is wide enough here.
4501 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
4502 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
4503 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
4504 length, not size_t. Use ptrdiff_t for index, not int.
4505 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
4506 possibility of integer overflow.
4507
4508 Overflow, signedness and related fixes for images.

4516 (cache_image, mark_image_cache, x_kill_gs_process, Flookup_image):
4517 * nsmenu.m (update_frame_tool_bar):
4518 * xdisp.c (calc_pixel_width_or_height):
4519 * xfns.c (image_cache_refcount):
4520 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
4521 on typical 64-bit hosts.
4522
4523 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
4524 (x_bitmap_pixmap, x_create_x_image_and_pixmap):

4527 when the callers expect that.
4528 (image_ascent): Redo ascent calculation to avoid int overflow.
4529 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
4530 (lookup_image): Remove unnecessary tests.
4531 (xbm_image_p): Locals are now of int, not EMACS_INT,
4532 since parse_image_check makes sure they fit into int.
4533 (png_load, gif_load, svg_load_image):
4534 Prefer int to unsigned where either will do.
4535 (tiff_handler): New function, combining the cores of the
4536 old tiff_error_handler and tiff_warning_handler.
4537 This function is rewritten to use vsnprintf and thereby avoid
4538 stack buffer overflows. It uses only the features of vsnprintf
4539 that are common to both POSIX and native Microsoft.
4540 (tiff_error_handler, tiff_warning_handler): Use it.
4541 (tiff_load, gif_load, imagemagick_load_image):
4542 Don't assume :index value fits in 'int'.
4543 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
4544 (imagemagick_load_image): Check that crop parameters fit into
4545 the integer types that MagickCropImage accepts. Don't assume
4546 Vimagemagick_render_type has a nonnegative value. Don't assume
4547 size_t fits in 'long'.
4548 (gs_load): Use printmax_t to print the widest integers possible.
4549 Check for integer overflow when computing image height and width.

4555
4556 2011-08-25 Eli Zaretskii <eliz@gnu.org>
4557
4558 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
4559 the display spec is of the form `(space ...)'.
4560 (handle_display_spec): Return the value returned by
4561 handle_single_display_spec, not just 1 or zero.
4562 (handle_single_display_spec): If the display spec is of the form
4563 `(space ...)', and specifies display in the text area, return 2
4564 rather than 1.
4565 (try_cursor_movement): Check for the need to scroll more
4566 accurately, and prefer exact match for point under bidi.
4567 Don't advance `row' beyond the last row of the window.
4568
4569 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
4570 into disp_prop; all users changed.
4571
4572 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
4573 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
4574 for the text covered by the display property.

4583
4584 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
4585 buffers, return left-to-right.
4586 (set_cursor_from_row): Consider candidate row a win if its glyph
4587 represents a newline and point is on that newline. Fixes cursor
4588 positioning on the newline at EOL of R2L text within L2R
4589 paragraph, and vice versa.
4590 (try_cursor_movement): Check continued rows, in addition to
4591 continuation rows. Fixes unwarranted scroll when point enters a
4592 continued line of R2L text within an L2R paragraph, or vice versa.
4593 (cursor_row_p): Consider the case of point being equal to
4594 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
4595 from the end of a short line to the beginning of a continued line
4596 of R2L text within L2R paragraph.
4597 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
4598 composed characters.
4599

4619
4620 * xdisp.c (redisplay_window): When computing centering_position,
4621 account for the height of the header line. (Bug#8874)
4622
4623 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
4624 instead of CHAR_TO_BYTE. Fixes a crash when a completion
4625 candidate is selected by the mouse, and that candidate has a
4626 composed character under the mouse.
4627
4628 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
4629 coordinates reported by pos-visible-in-window-p for a composed
4630 character in column zero.
4631
4632 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

4636 2011-08-22 Eli Zaretskii <eliz@gnu.org>
4637
4638 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
4639 consider it a hit if to_charpos is anywhere in the range of the
4640 composed buffer positions.
4641
4642 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
4643
4644 * image.c (gif_load): Don't assume that each subimage has the same
4645 dimensions as the base image. Handle disposal method that is
4646 "undefined" by the gif spec (Bug#9335).
4647
4648 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
4649

4652
4653 2011-08-19 Eli Zaretskii <eliz@gnu.org>
4654
4655 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
4656 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
4657 from an Org mode buffer to a Speedbar frame.
4658
4659 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
4660 a composition, take its buffer position from IT->cmp_it.charpos.
4661 Fixes cursor positioning at the beginning of a line that begins
4662 with a composed character.
4663
4664 2011-08-18 Eli Zaretskii <eliz@gnu.org>
4665
4666 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
4667 character bidirectional type, use STRONG_L instead. Fixes crashes
4668 in a buffer produced by `describe-categories'.
4669
4670 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
4671 members before the level stack, so they would be saved and
4672 restored when copying iterator state. Fixes incorrect reordering
4673 around TABs covered by display properties.
4674
4675 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
4676

4760 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
4761 the event loop. Get status from as_status (Bug#7276).
4762
4763 * nsterm.m (sendEvent): If event is NSApplicationDefined and
4764 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
4765 the event loop (Bug#7276).

4794 sockaddr.
4795 (struct ifflag_def): notrailers is smart on OSX.
4796 (Fnetwork_interface_info): Handle case when ifr_flags is negative.

4800
4801 * xdisp.c (iterate_out_of_display_property): xassert that
4802 IT->position is set to within IT->object's boundaries. Break from
4803 the loop as soon as EOB is reached; avoids infloops in redisplay
4804 when IT->position is set up wrongly due to some bug.
4805 Set IT->current to match the bidi iterator unconditionally.
4806 (push_display_prop): Allow GET_FROM_STRING as IT->method on
4807 entry. Force push_it to save on the stack the current
4808 buffer/string position, to be restored by pop_it. Fix flags in
4809 the iterator structure wrt the object coming from a display
4810 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
4811 properties. (Bug#9284)
4812
4813 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
4814

4851
4852 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
4853 display property strides EOL and includes a newline, as in
4854 longlines-mode. (Bug#9254)
4855 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
4856 word-wrap under bidirectional display. (Bug#9224)
4857
4858 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
4859 is non-zero, even if the data buffer is NULL. Fixes a crash in
4860 vertical-motion with longlines-mode. (Bug#9254)
4861
4862 2011-08-05 Eli Zaretskii <eliz@gnu.org>

4868 cache. (Bug#9221)
4869
4870 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
4871 amount allocated this far in `bidi_cache_total_alloc'.
4872 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
4873 non-zero, only free the data buffer without restoring the cache
4874 contents. All callers changed.
4875
4876 * dispextern.h (bidi_unshelve_cache): Update prototype.
4877
4878 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
4879 (move_it_in_display_line, move_it_to)
4880 (move_it_vertically_backward, move_it_by_lines): Replace the call
4881 to xfree to an equivalent call to bidi_unshelve_cache.
4882 (move_it_in_display_line_to): Fix logic of returning
4883 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
4884
4885 2011-08-05 Eli Zaretskii <eliz@gnu.org>
4886
4887 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
4888 came from a string character with a `cursor' property. (Bug#9229)
4889
4890 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
4891
4892 * Makefile.in (LIB_PTHREAD): New variable.
4893 (LIBES): Add LIB_PTHREAD (Bug#9216).
4894
4895 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
4896 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
4897
4898 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
4899
4900 * regex.c (re_iswctype): Remove some redundant boolean conversions.
4901
4902 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
4903
4904 * xterm.c (x_find_topmost_parent): New function.
4905 (x_set_frame_alpha): Find topmost parent window with
4906 x_find_topmost_parent and set the property there also (bug#9181).
4907 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
4908
4909 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
4910
4911 * callproc.c (Fcall_process): Avoid vfork clobbering
4912 the local vars buffer, coding_systems, current_dir.
4913
4914 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
4915
4916 * keymap.c (Fmake_composed_keymap): Move to subr.el.
4917
4918 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
4919
4920 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
4921 so that it is not optimized away.
4922
4923 * xdisp.c (compute_display_string_pos): Remove unused local.
4924
4925 2011-08-02 Eli Zaretskii <eliz@gnu.org>
4926
4927 Fix slow cursor motion and scrolling in large buffers with
4928 selective display, like Org Mode buffers. (Bug#9218)
4929
4930 * dispextern.h (struct bidi_it): New member disp_prop_p.
4931
4932 * xdisp.c: Remove one-slot cache of display string positions.
4933 (compute_display_string_pos): Accept an additional argument
4934 DISP_PROP_P; callers changed. Scan at most 5K characters forward
4935 for a display string or property. If found, set DISP_PROP_P
4936 non-zero.
4937
4938 * bidi.c (bidi_fetch_char): Accept an additional argument
4939 DISP_PROP_P, and pass it to compute_display_string_pos.
4940 Only handle text covered by a display string if DISP_PROP_P is returned
4941 non-zero. All callers of bidi_fetch_char changed.
4942
4943 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
4944
4945 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
4946
4947 2010-12-03 Don March <don@ohspite.net>
4948
4949 * keymap.c (Fdefine_key): Fix non-prefix key error message when
4950 last character M-[char] is translated to ESC [char] (bug#7541).
4951
4952 2011-08-02 Kenichi Handa <handa@m17n.org>
4953
4954 * lisp.h (uniprop_table): Extern it.
4955
4956 * chartab.c (uniprop_table): Make it non-static.
4957
4958 2011-08-01 Eli Zaretskii <eliz@gnu.org>
4959
4960 * xdisp.c (forward_to_next_line_start): Accept additional argument
4961 BIDI_IT_PREV, and store into it the state of the bidi iterator had
4962 on the newline.
4963 (reseat_at_next_visible_line_start): Use the bidi iterator state
4964 returned by forward_to_next_line_start to restore the state of
4965 it->bidi_it after backing up to previous newline. (Bug#9212)
4966
4967 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
4968
4969 * regex.c (re_comp): Protoize.
4970 (re_exec): Fix return type.
4971 (regexec): Fix type of `ret'. (Bug#9203)
4972
4973 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
4974
4975 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
4976 This is needed if max-image-size is a floating-point number.
4977
4978 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
4979
4980 * print.c (print_object): Print empty symbol as ##.
4981
4982 * lread.c (read1): Read ## as empty symbol.
4983
4984 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
4985
4986 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
4987 setting frame foreground color (Bug#9175).
4988 (x_set_background_color): Likewise.
4989
4990 * nsmenu.m (-setText): Size tooltip dimensions precisely to
4991 contents (Bug#9176).
4992 (EmacsTooltip -init): Remove bezels and add shadows to
4993 tooltip windows.
4994
4995 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
4996 or scroll bar (Bug#8470).
4997
4998 * nsfont.m (nsfont_open): Remove assignment to voffset and
4999 unnecessary vars hshink, expand, hd, full_height, min_height.
5000 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
5001
5002 * nsterm.h (nsfont_info): Remove voffset field.
5003
5004 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
5005
5006 Implement strike-through and overline on NextStep (Bug#8863).
5007
5008 * nsfont.m (nsfont_open): Use underline position provided by font,
5009 instead of hard-coded value of 2.
5010 (nsfont_draw): Call ns_draw_text_decoration instead.
5011
5012 * nsterm.h: Add declaration for ns_draw_text_decoration.
5013
5014 * nsterm.m (ns_draw_text_decoration): New function for drawing
5015 underline, overline, and strike-through.
5016 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
5017 ns_draw_text_decoration. Change treatment of cursor drawing to
5018 accommodate underlining, etc.
5019
5020 2011-07-28 Eli Zaretskii <eliz@gnu.org>
5021
5022 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
5023 default.
5024
5025 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
5026
5027 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
5028 Without this fix, if a signal arrives just after memory fills up,
5029 'malloc' might be invoked reentrantly.
5030
5031 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
5032 In other words, assume that every image size is allowed, on non-X
5033 hosts. This assumption is probably wrong, but it lets Emacs compile.
5034
5035 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
5036
5037 * regex.c (re_iswctype): Convert return values to boolean.
5038
5039 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
5040
5041 * xdisp.c (compute_display_string_pos): Don't use cached display
5042 string position if the buffer had its restriction changed.
5043 (Bug#9184)
5044
5045 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
5046
5047 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
5048
5049 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
5050
5051 Integer signedness and overflow and related fixes. (Bug#9079)
5052
5053 * bidi.c: Integer size and overflow fixes.
5054 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
5055 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
5056 (bidi_cache_find_level_change, bidi_cache_ensure_space)
5057 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
5058 (bidi_find_other_level_edge):
5059 Use ptrdiff_t instead of EMACS_INT where either will do.
5060 This works better on 32-bit hosts configured --with-wide-int.
5061 (bidi_cache_ensure_space): Check for size-calculation overflow.
5062 Use % rather than repeated addition, for better worst-case speed.
5063 Don't set bidi_cache_size until after xrealloc returns, because it
5064 might not return.
5065 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
5066 (bidi_cache_ensure_space): Also check that the bidi cache size
5067 does not exceed that of the largest Lisp string or buffer. See Eli
5068 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
5069
5070 * alloc.c (__malloc_size_t): Remove.
5071 All uses replaced by size_t. See Andreas Schwab's note
5072 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
5073
5074 * image.c: Improve checking for integer overflow.
5075 (check_image_size): Assume that f is nonnull, since
5076 it is always nonnull in practice. This is one less thing to
5077 worry about when checking for integer overflow later.
5078 (x_check_image_size): New function, which checks for integer
5079 overflow issues inside X.
5080 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
5081 This removes the need for a memory_full check.
5082 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
5083 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
5084 (xbm_read_bitmap_data): Change locals back to 'int', since
5085 their values must fit in 'int'.
5086 (xpm_load_image, png_load, tiff_load):
5087 Invoke x_create_x_image_and_pixmap earlier,
5088 to avoid much needless work if the image is too large.
5089 (tiff_load): Treat overly large images as if
5090 x_create_x_image_and_pixmap failed, not as malloc failures.
5091 (gs_load): Use x_check_image_size.
5092
5093 * gtkutil.c: Omit integer casts.
5094 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
5095 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
5096
5097 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
5098
5099 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
5100 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
5101 would wrongly return t on a 64-bit host.
5102
5103 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
5104 The plain *_OVERFLOW macros run afoul of GCC bug 49705
5105 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
5106 and therefore cause GCC to emit a bogus diagnostic in some cases.
5107
5108 * image.c: Integer signedness and overflow and related fixes.
5109 This is not an exhaustive set of fixes, but it's time to
5110 record what I've got.
5111 (lookup_pixel_color, check_image_size): Remove redundant decls.
5112 (check_image_size): Don't assume that arbitrary EMACS_INT values
5113 fit in 'int', or that arbitrary 'double' values fit in 'int'.
5114 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
5115 (tiff_load, imagemagick_load_image):
5116 Check for overflow in size calculations.
5117 (x_create_x_image_and_pixmap): Remove unnecessary test for
5118 xmalloc returning NULL; that can't happen.
5119 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
5120 (xpm_color_bucket): Use better integer hashing function.
5121 (xpm_cache_color): Don't possibly over-allocate memory.
5122 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
5123 (gif_memory_source):
5124 Use ptrdiff_t, not int or size_t, to record sizes.
5125 (png_load): Don't assume values greater than 2**31 fit in 'int'.
5126 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
5127 either works, as we prefer signed integers.
5128 (tiff_read_from_memory, tiff_write_from_memory):
5129 Return tsize_t, not size_t, since that's what the TIFF API wants.
5130 (tiff_read_from_memory): Don't fail simply because the read would
5131 go past EOF; instead, return a short read.
5132 (tiff_load): Omit no-longer-needed casts.
5133 (Fimagemagick_types): Don't assume size fits into 'int'.
5134
5135 Improve hashing quality when configured --with-wide-int.
5136 * fns.c (hash_string): New function, taken from sxhash_string.
5137 Do not discard information about ASCII character case; this
5138 discarding is no longer needed.
5139 (sxhash-string): Use it. Change sig to match it. Caller changed.
5140 * lisp.h: Declare it.
5141 * lread.c (hash_string): Remove, since we now use fns.c's version.
5142 The fns.c version returns a wider integer if --with-wide-int is
5143 specified, so this should help the quality of the hashing a bit.
5144
5145 * emacs.c: Integer overflow minor fix.
5146 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
5147 Define only if GNU_LINUX.
5148 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
5149
5150 * dispnew.c: Integer signedness and overflow fixes.
5151 Remove unnecessary forward decls, that were a maintenance hassle.
5152 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
5153 All uses changed.
5154 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
5155 (scrolling_window): Use ptrdiff_t, not int, for byte count.
5156 (prepare_desired_row, line_draw_cost):
5157 Use int, not unsigned, where either works.
5158 (save_current_matrix, restore_current_matrix):
5159 Use ptrdiff_t, not size_t, where either works.
5160 (init_display): Check for overflow more accurately, and without
5161 relying on undefined behavior.
5162
5163 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
5164 Remove, replacing with the new symbols in lisp.h. All uses changed.
5165 * fileio.c (make_temp_name):
5166 * filelock.c (lock_file_1, lock_file):
5167 * xdisp.c (message_dolog):
5168 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
5169 Use pMd etc. instead.
5170 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
5171 replacing the pWIDE etc. symbols removed from editfns.c.
5172
5173 * keyboard.h (num_input_events): Now uintmax_t.
5174 This is (very slightly) less likely to mess up due to wraparound.
5175 All uses changed.
5176
5177 * buffer.c: Integer signedness fixes.
5178 (alloc_buffer_text, enlarge_buffer_text):
5179 Use ptrdiff_t rather than size_t when either will do, as we prefer
5180 signed integers.
5181
5182 * alloc.c: Integer signedness and overflow fixes.
5183 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
5184 (__malloc_size_t): Default to size_t, not to int.
5185 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
5186 (Fgarbage_collect, mark_object_loop_halt, mark_object):
5187 Prefer ptrdiff_t to size_t when either would do, as we prefer
5188 signed integers.
5189 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
5190 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
5191 Now const. Initialize with values that are in range even if char
5192 is signed.
5193 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
5194 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
5195 These functions do the right thing with sizes > 2**32.
5196 (check_depth): Now ptrdiff_t, not int.
5197 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
5198 Adjust to new way of storing sizes. Check for size overflow bugs
5199 in rest of code.
5200 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
5201 slightly wrong anyway, as it missed one instance of
5202 XMALLOC_OVERRUN_CHECK_OVERHEAD.
5203 (refill_memory_reserve): Omit needless cast to size_t.
5204 (mark_object_loop_halt): Mark as externally visible.
5205
5206 * xselect.c: Integer signedness and overflow fixes.
5207 (Fx_register_dnd_atom, x_handle_dnd_message):
5208 Use ptrdiff_t, not size_t, since we prefer signed.
5209 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
5210 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
5211 x_dnd_atoms_size and x_dnd_atoms_length.
5212
5213 * doprnt.c: Prefer signed to unsigned when either works.
5214 * eval.c (verror):
5215 * doprnt.c (doprnt):
5216 * lisp.h (doprnt):
5217 * xdisp.c (vmessage):
5218 Use ptrdiff_t, not size_t, when using or implementing doprnt,
5219 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
5220 prefer signed arithmetic to avoid comparison confusion.
5221 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
5222 but is a bit tricky.
5223
5224 Assume freestanding C89 headers, string.h, stdlib.h.
5225 * data.c, doprnt.c, floatfns.c, print.c:
5226 Include float.h unconditionally.
5227 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
5228 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
5229 * regex.c: Likewise for stddef.h, string.h.
5230 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
5231 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
5232 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
5233 (STDC_HEADERS): Remove obsolete defines.
5234 * sysdep.c: Include limits.h unconditionally.
5235
5236 Assume support for memcmp, memcpy, memmove, memset.
5237 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
5238 * regex.c (memcmp, memcpy):
5239 Remove; we assume C89 now.
5240
5241 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
5242 (__malloc_safe_bcopy): Remove; no longer needed.
5243
5244 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
5245 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
5246 well either way, and we prefer signed to unsigned.
5247
5248 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
5249
5250 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
5251 closes the connection while we're reading (bug#9182).
5252
5253 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
5254
5255 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
5256 are specified (Bug#9168).
5257
5258 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
5259
5260 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
5261 Found by GCC static checking and --with-wide-int on a 32-bit host.
5262
5263 2011-07-25 Eli Zaretskii <eliz@gnu.org>
5264
5265 * xdisp.c (compute_display_string_pos): Fix logic of caching
5266 previous display string position. Initialize cached_prev_pos to
5267 -1. Fixes slow-down at the beginning of a buffer.
5268
5269 2011-07-24 Eli Zaretskii <eliz@gnu.org>
5270
5271 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
5272 for attrs[LFACE_FONTSET_INDEX].
5273
5274 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
5275
5276 * xml.c (parse_region): Remove unused local
5277 that was recently introduced.
5278
5279 2011-07-23 Eli Zaretskii <eliz@gnu.org>
5280
5281 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
5282 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
5283
5284 * xdisp.c (move_it_in_display_line_to): Record the best matching
5285 position for TO_CHARPOS while scanning the line, and restore it on
5286 exit if none of the characters scanned was an exact match.
5287 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
5288 when exact match is impossible due to invisible text, and the

5293 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
5294 for OSX >= 10.7.
5295
5296 2011-07-22 Eli Zaretskii <eliz@gnu.org>
5297
5298 Fix a significant slow-down of cursor motion with C-n, C-p,
5299 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
5300 auto-repeat under bidi redisplay in fontified buffers.
5301 * xdisp.c (compute_stop_pos_backwards): New function.
5302 (next_element_from_buffer): Call compute_stop_pos_backwards to
5303 find a suitable prev_stop when we find ourselves before
5304 base_level_stop.
5305 (reseat): Don't look for prev_stop, as that could mean a very long
5306 run.
5307 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
5308 <cached_disp_overlay_modiff>: Cache for last found display string
5309 position.
5310 (compute_display_string_pos): Return the cached position if asked
5311 about the same buffer in the same area of character positions, and
5312 the buffer wasn't changed since the time the display string
5313 position was cached.
5314
5315 2011-07-22 Eli Zaretskii <eliz@gnu.org>
5316
5317 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
5318 is an integer, which is important for empty lines. (Bug#9149)
5319
5320 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
5321
5322 * frame.c (Fmodify_frame_parameters): In tty case, update the
5323 default face if necessary (Bug#4238).
5324
5325 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
5326
5327 * editfns.c (Fstring_to_char): No need to explain what a character
5328 is in the docstring (Bug#6576).
5329
5330 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
5331
5332 * xml.c (parse_region): Make sure we always return a tree.
5333
5334 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
5335
5336 * xml.c (parse_region): If a document contains only comments,
5337 return that, too.
5338
5339 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
5340
5341 * xml.c (make_dom): Return comments, too.

5345 Port to OpenBSD.
5346 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
5347 and the surrounding thread.
5348 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
5349 rather than fgets, and retry after EINTR. Otherwise, 'emacs
5350 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
5351 timer goes off.
5352 * s/openbsd.h (BROKEN_SIGIO): Define.
5353 * unexelf.c (unexec) [__OpenBSD__]:
5354 Don't update the .mdebug section of the Alpha COFF symbol table.
5355
5356 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
5357
5358 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
5359 (bug#8460).
5360
5361 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
5362
5363 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
5364 This fixes some race conditions on the permissions of any newly
5365 created file.
5366
5367 * alloc.c (valid_pointer_p): Use pipe, not open.
5368 This fixes some permissions issues when debugging.
5369
5370 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
5371 If fchown fails to set both uid and gid, try to set just gid,
5372 as that is sometimes allowed. Adjust the file's mode to eliminate
5373 setuid or setgid bits that are inappropriate if fchown fails.
5374
5375 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
5376
5377 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
5378 to compare Lisp_Objects.
5379 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
5380 global_gnutls_log_level, don't mistake it for a Lisp_Object.
5381 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
5382
5383 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
5384
5385 * lread.c (read_integer): Unread even EOF character.
5386 (read1): Likewise. Properly record start position of symbol.
5387
5388 * lread.c (read1): Read `#:' as empty uninterned symbol if no
5389 symbol character follows.
5390
5391 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
5392
5393 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
5394 This works around a problem with the previous change to Fcopy_file.
5395 Recent glibc declares fchown with __attribute__((warn_unused_result)),
5396 and without this change, GCC might complain about discarding
5397 fchown's return value.
5398
5399 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
5400
5401 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
5402
5403 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
5404
5405 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
5406
5407 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
5408
5409 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
5410 it's used from the C level.
5411
5412 * process.c: Use the same condition for POLL_FOR_INPUT in both
5413 keyboard.c and process.c (bug#1858).
5414
5415 2011-07-09 Lawrence Mitchell <wence@gmx.li>
5416
5417 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
5418 (Fgnutls_boot): Use it.
5419
5420 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
5421
5422 * doc.c (Fsubstitute_command_keys): Revert last change.
5423
5424 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
5425
5426 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
5427 quotes the next character, and doesn't affect other longer
5428 sequences (bug#8935).
5429
5430 * lread.c (syms_of_lread): Clarify that is isn't only
5431 `eval-buffer' and `eval-defun' that's affected by
5432 `lexical-binding' (bug#8460).
5433
5434 2011-07-15 Eli Zaretskii <eliz@gnu.org>
5435
5436 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
5437 bidi redisplay when a line includes both an image and is truncated.
5438
5439 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
5440
5441 Fix minor problems found by static checking.
5442 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
5443 (elsz): Now a signed constant, not a size_t var. We prefer signed
5444 types to unsigned, to avoid integer comparison confusion. Without
5445 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
5446 "cannot optimize loop, the loop counter may overflow", a symptom
5447 of the confusion.
5448 * indent.c (Fvertical_motion): Mark locals as initialized.
5449 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
5450
5451 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
5452
5453 * search.c (Fre_search_backward): Mention `case-fold-search' in
5454 all the re_search_* functions (bug#8138).
5455
5456 * keyboard.c (Fopen_dribble_file): Document when the file is
5457 closed (bug#8056).
5458
5459 2011-07-14 Eli Zaretskii <eliz@gnu.org>

5461 * bidi.c (bidi_dump_cached_states): Fix format of displaying
5462 bidi_cache_idx.
5463
5464 Support bidi reordering of display and overlay strings.
5465 * xdisp.c (compute_display_string_pos)
5466 (compute_display_string_end): Accept additional argument STRING.
5467 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.

5471 NULL (avoids a crash in bidi_paragraph_init).
5472 Initialize itb.string.lstring.
5473 (init_iterator): Call bidi_init_it only of a valid
5474 buffer position was specified. Initialize paragraph_embedding to
5475 L2R.
5476 (reseat_to_string): Initialize the bidi iterator.
5477 (display_string): If we need to ignore text properties of
5478 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
5479 original value of -1 will not work with bidi.)
5480 (compute_display_string_pos): First arg is now struct
5481 `text_pos *'; all callers changed. Support display properties on
5482 Lisp strings.
5483 (compute_display_string_end): Support display properties on Lisp
5484 strings.
5485 (init_iterator, reseat_1, reseat_to_string): Initialize the
5486 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
5487 when iterating on a string not from display properties).
5488 (compute_display_string_pos, compute_display_string_end):
5489 Fix calculation of the object to scan. Fixes an error when using
5490 arrow keys.
5491 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
5492 base_level_stop; instead, set base_level_stop to BEGV.
5493 Fixes crashes in vertical-motion.
5494 (next_element_from_buffer): Improve commentary for when
5495 the iterator is before prev_stop.
5496 (init_iterator): Initialize bidi_p from the default value of
5497 bidi-display-reordering, not from buffer-local value. Use the
5498 buffer-local value only if initializing for buffer iteration.
5499 (handle_invisible_prop): Support invisible properties on strings
5500 that are being bidi-reordered.
5501 (set_iterator_to_next): Support bidi reordering of C strings and
5502 Lisp strings.

5516 (next_element_from_c_string): Handle the case of the first string
5517 character that is not the first one in the visual order.
5518 (get_visually_first_element): New function, refactored from common
5519 parts of next_element_from_buffer, next_element_from_string, and
5520 next_element_from_c_string.
5521 (tool_bar_lines_needed, redisplay_tool_bar)
5522 (display_menu_bar): Force left-to-right direction. Add a FIXME
5523 comment for making that be controlled by a user option.
5524 (push_it, pop_it): Save and restore the state of the
5525 bidi iterator. Save and restore the bidi_p flag.
5526 (pop_it): Iterate out of display property for string iteration as

5532 (get_overlay_strings_1, push_display_prop): Set up the bidi
5533 iterator for displaying display or overlay strings.
5534 (forward_to_next_line_start): Don't use the shortcut if
5535 bidi-iterating.
5536 (back_to_previous_visible_line_start): If handle_display_prop
5537 pushed the iterator stack, restore the internal state of the bidi
5538 iterator by calling bidi_pop_it same number of times.
5539 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
5540 and we are bidi-iterating, don't decrement the iterator position;
5541 instead, set the first_elt flag in the bidi iterator, to produce
5542 the same effect.
5543 (reseat_1): Remove redundant setting of string_from_display_prop_p.
5544 (push_display_prop): xassert that we are iterating a buffer.
5545 (push_it, pop_it): Save and restore paragraph_embedding member.
5546 (handle_single_display_spec, next_overlay_string)
5547 (get_overlay_strings_1, reseat_1, reseat_to_string)

5556 (pop_it): Call iterate_out_of_display_property only if we are
5557 popping after iteration over a string that came from a display
5558 property. Fix a typo in popping stretch info. Add an assertion
5559 for verifying that the iterator position is in sync with the bidi
5560 iterator.
5561 (handle_single_display_spec, get_overlay_strings_1)
5562 (push_display_prop): Fix initialization of paragraph direction for
5563 string when that of the parent object is not yet determined.
5564 (reseat_1): Call bidi_init_it to resync the bidi
5565 iterator with IT's position. (Bug#7616)
5566 (find_row_edges): If ROW->start.pos gives position
5567 smaller than min_pos, use it as ROW->minpos. (Bug#7616)
5568 (handle_stop, back_to_previous_visible_line_start, reseat_1):
5569 Reset the from_disp_prop_p flag.
5570 (SAVE_IT, RESTORE_IT): New macros.

5575 (try_scrolling, redisplay_window, display_line): Use them when
5576 saving a temporary copy of the iterator and restoring it back.
5577 (back_to_previous_visible_line_start, reseat_1)
5578 (init_iterator): Empty the bidi cache "stack".
5579 (move_it_in_display_line_to): If iterator ended up at
5580 EOL, but we never saw any buffer positions smaller than
5581 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
5582 motion in bidi-reordered lines.
5583 (move_it_in_display_line_to): Record prev_method and prev_pos
5584 immediately before the call to set_iterator_to_next. Fixes cursor
5585 motion in bidi-reordered lines with stretch glyphs and strings
5586 displayed in margins. (Bug#8133) (Bug#8867)
5587 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
5588 TO_CHARPOS.
5589 (pos_visible_p): Support positions in bidi-reordered lines.
5590 Save and restore bidi cache.
5591
5592 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.

5604 (bidi_fetch_char): Accept new argument STRING; all callers
5605 changed. Support iteration over a string. Support strings with
5606 display properties. Support unibyte strings. Fix the type of
5607 `len' according to what STRING_CHAR_AND_LENGTH expects.
5608 (bidi_paragraph_init, bidi_resolve_explicit_1)
5609 (bidi_resolve_explicit, bidi_resolve_weak)
5610 (bidi_level_of_next_char, bidi_move_to_visually_next):

5628 (bidi_initialize): Initialize the bidi cache start stack pointer.
5629 (bidi_cache_ensure_space): New function, refactored from part of

5649 Update prototypes.
5650 (bidi_push_it, bidi_pop_it): Add prototypes.
5651 (struct iterator_stack_entry): New members bidi_p,
5652 paragraph_embedding, and from_disp_prop_p.

5704
5705 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
5706 The old code sometimes used this field without initializing it.
5707
5708 * alloc.c (gc_sweep): Don't read past end of array.
5709 In theory, the old code could also have corrupted Emacs internals,
5710 though it'd be very unlikely.
5711
5712 2011-07-12 Andreas Schwab <schwab@linux-m68k.org>
5713
5714 * character.c (Fcharacterp): Don't advertise optional ignored

5810
5811 2011-07-08 Paul Eggert <eggert@cs.ucla.edu>
5812
5813 Use pthread_sigmask, not sigprocmask (Bug#9010).
5814 sigprocmask is portable only for single-threaded applications, and
5815 Emacs can be multi-threaded when it uses GTK.

5973 (clone_per_buffer_values): Don't assume that

5978 New macros, used in the buffer.c change.

6013
6014 Random fixes. E.g., (random) never returned negative values.
6015 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
6016 subseconds part to the entropy, as that's a bit more random.
6017 Prefer signed to unsigned, since the signedness doesn't matter and
6018 in general we prefer signed. When given a limit, use a
6019 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
6020 latter isn't right if USE_2_TAGS_FOR_INTS.
6021 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
6022 not 0..VALMASK. Don't discard "excess" bits that random () returns.

6032 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
6033
6034 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
6035 This is more efficient than Ffile_directory_p and avoids a minor race.
6036
6037 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
6038
6039 * buffer.c (Foverlay_put): Say what the return value is

6046 error be more correct.

6062 Qgnutls_bootprop_verify_error (which is no longer used).
6063
6064 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
6065 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
6066 Also (re)move comments that are misplaced or no longer relevant.

6088 2011-07-02 Chong Yidong <cyd@stupidchicken.com>

6092
6093 2011-07-02 Lars Magne Ingebrigtsen <larsi@gnus.org>

6167 * eval.c (struct backtrace): Simplify and port the data structure.
6168 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
6169 signed bit field, as this assumption is not portable and it makes
6170 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
6171 "char debug_on_exit : 1" as this is not portable either; instead,
6172 use the portable "unsigned int debug_on_exit : 1". Remove unused
6173 member evalargs. Remove obsolete comments about cc bombing out.

6213 2011-06-27 Martin Rudalics <rudalics@gmx.at>
6214
6215 * buffer.c (Qclone_number): Declare static and DEFSYM it.
6216 (sort_overlays, overlay_strings): When an overlay's clone number
6217 matches the window's clone number process the overlay even if
6218 the overlay's window property doesn't match the current window.
6219
6220 * window.c (Fwindow_vchild): Rename to Fwindow_top_child.

6256
6257 * bidi.c (bidi_paragraph_init): Test for ZV_BYTE before calling
6258 bidi_at_paragraph_end, since fast_looking_at doesn't like to be

6350 * keyboard.h (struct keyboard.kbd_macro_bufsize):
6351 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):

6358
6359 * lread.c: Integer overflow fixes.
6360 (read_integer): Radix is now EMACS_INT, not int,
6361 to improve quality of diagnostics for out-of-range radices.
6362 Calculate buffer size correctly for out-of-range radices.
6363 (read1): Check for integer overflow in radices, and in
6364 read-circle numbers.
6365 (read_escape): Avoid int overflow.
6366 (Fload, openp, read_buffer_size, read1)
6367 (substitute_object_recurse, read_vector, read_list, map_obarray):
6368 Use ptrdiff_t, not int, for sizes.

6389
6390 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
6391 The following patches are for when GLYPH_DEBUG && !XASSERT.
6392 * dispextern.h (trace_redisplay_p, dump_glyph_string):
6393 * dispnew.c (flush_stdout):
6394 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
6395 Mark as externally visible.
6396 * dispnew.c (check_window_matrix_pointers): Now static.

6406 Now static.
6407 (debug_method_add): Use va_list and vsprintf rather than relying
6408 on undefined behavior with wrong number of arguments.
6409 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
6410 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
6411 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
6412 since we're not interested in debugging glyphs with old libraries.
6413 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
6414 GCC 4.6.0's static checking.
6415
6416 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>

6473
6474 * xdisp.c (message_log_check_duplicate): Return intmax_t,
6475 not unsigned long, as we prefer signed integers. All callers changed.
6476 Detect integer overflow in repeat count.
6477 (message_dolog): Don't assume print length fits in 39 bytes.
6478 (display_mode_element): Don't assume strlen fits in int.
6479

6503 (lock_info_type, lock_file_1, lock_file):
6504 Don't assume pid_t and time_t fit in unsigned long.
6505 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
6506 (current_lock_owner): Prefer signed type for sizes.
6507 Use memcpy, not strncpy, where memcpy is what is really wanted.

6525 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
6526 We prefer signed integers, even for size calculations.
6527
6528 * emacs.c: Don't assume string length fits in 'int'.
6529 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
6530 (main): Don't invoke strlen when not needed.
6531
6532 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
6533 (XD_DEBUG_MESSAGE): Don't waste a byte.
6534
6535 * callproc.c (getenv_internal_1, getenv_internal)
6536 (Fgetenv_internal):
6537 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
6538
6539 * lread.c (invalid_syntax): Omit length argument.
6540 All uses changed. This doesn't fix a bug, but it simplifies the
6541 code away from its former Hollerith-constant appearance, and it's
6542 one less 'int' to worry about when looking at integer-overflow issues.
6543 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
6544
6545 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
6546 This didn't break anything, but it didn't help either.
6547 It's confusing to put a bogus integer in a place where the actual
6548 value does not matter.
6549 (LIST_END_P): Remove unused macro and its bogus comment.
6550 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
6551
6552 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
6553 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
6554 implementation.
6555 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
6556 We prefer signed types, and the value cannot exceed the EMACS_INT
6557 range anyway (because otherwise the length would not be representable).
6558 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
6559 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
6560 This avoids a GCC warning when WIDE_EMACS_INT.
6561
6562 * indent.c (sane_tab_width): New function.
6563 (current_column, scan_for_column, Findent_to, position_indentation)
6564 (compute_motion): Use it. This is just for clarity.
6565 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
6566
6567 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
6568
6569 * lisp.h (lint_assume): New macro.
6570 * composite.c (composition_gstring_put_cache):
6571 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
6572
6573 * editfns.c, insdel.c:
6574 Omit unnecessary forward decls, to simplify future changes.
6575
6576 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
6577
6578 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
6579
6580 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
6581 Use much-faster test for byte-length change.
6582 Don't assume string byte-length fits in 'int'.
6583 Check that character arg fits in 'int'.
6584 (mapcar1): Declare byte as byte, for clarity.
6585
6586 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
6587
6588 * fns.c (concat): Catch string overflow earlier.
6589 Do not rely on integer wraparound.
6590
6591 * dispextern.h (struct it.overlay_strings_charpos)
6592 (struct it.selective): Now EMACS_INT, not int.
6593 * xdisp.c (forward_to_next_line_start)
6594 (back_to_previous_visible_line_start)
6595 (reseat_at_next_visible_line_start, next_element_from_buffer):
6596 Don't arbitrarily truncate the value of 'selective' to int.
6597
6598 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
6599
6600 * composite.c: Don't truncate sizes to 'int'.
6601 (composition_gstring_p, composition_reseat_it)
6602 (composition_adjust_point): Use EMACS_INT, not int.
6603 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
6604 not EMACS_UINT, for indexes.
6605
6606 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
6607
6608 * buffer.c: Include <verify.h>.
6609 (struct sortvec.priority, struct sortstr.priority):
6610 Now EMACS_INT, not int.
6611 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
6612 (struct sortstr.size, record_overlay_string)
6613 (struct sortstrlist.size, struct sortlist.used):
6614 Don't truncate size to int.
6615 (record_overlay_string): Check for size-calculation overflow.
6616 (init_buffer_once): Check at compile-time, not run-time.
6617
6618 2011-06-22 Jim Meyering <meyering@redhat.com>
6619
6620 Don't leak an XBM-image-sized buffer
6621 * image.c (xbm_load): Free the image buffer after using it.
6622
6623 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
6624
6625 Port to Sun C.
6626 * composite.c (find_automatic_composition): Omit needless 'return 0;'
6627 that Sun C diagnosed.
6628 * fns.c (secure_hash): Fix pointer signedness issue.
6629 * intervals.c (static_offset_intervals): New function.
6630 (offset_intervals): Use it.
6631
6632 2011-06-21 Leo Liu <sdl.web@gmail.com>
6633
6634 * deps.mk (fns.o):
6635 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
6636 sha512.h.
6637
6638 * fns.c (secure_hash): Rename from crypto_hash_function and change
6639 the first arg to accept symbols.
6640 (Fsecure_hash): New primitive.
6641 (syms_of_fns): New symbols.
6642
6643 2011-06-20 Deniz Dogan <deniz@dogan.se>
6644
6645 * process.c (Fset_process_buffer): Clarify return value in
6646 docstring.
6647
6648 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
6649
6650 * dispnew.c (add_window_display_history): Use BVAR.
6651
6652 * xdisp.c (debug_method_add): Use BVAR.
6653 (check_window_end, dump_glyph_matrix, dump_glyph)
6654 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
6655
6656 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
6657 Likewise.
6658
6659 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
6660 check till after the cache is created in init_frame_faces.
6661
6662 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
6663
6664 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
6665
6666 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
6667
6668 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
6669 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
6670 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
6671
6672 Improve buffer-overflow checking (Bug#8873).
6673 * fileio.c (Finsert_file_contents):
6674 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
6675 Remove the old (too-loose) buffer overflow checks.
6676 They weren't needed, since make_gap checks for buffer overflow.
6677 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
6678 The old code merely checked for Emacs fixnum overflow, and relied
6679 on undefined (wraparound) behavior. The new code avoids undefined
6680 behavior, and also checks for ptrdiff_t and/or size_t overflow.
6681
6682 * editfns.c (Finsert_char): Don't dump core with very negative counts.
6683 Tune. Don't use wider integers than needed. Don't use alloca.
6684 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
6685
6686 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
6687
6688 * insdel.c, lisp.h (buffer_overflow): New function.
6689 (insert_from_buffer_1, replace_range, replace_range_2):
6690 * insdel.c (make_gap_larger):
6691 * editfns.c (Finsert_char):
6692 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
6693
6694 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
6695
6696 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
6697
6698 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
6699
6700 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
6701 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
6702
6703 * fileio.c: Don't assume EMACS_INT fits in off_t.
6704 (emacs_lseek): New static function.
6705 (Finsert_file_contents, Fwrite_region): Use it.
6706 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
6707
6708 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
6709
6710 * fns.c: Don't overflow int when computing a list length.
6711 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
6712 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
6713 truncation on 64-bit hosts. Check for QUIT every
6714 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
6715 faster and is responsive enough.
6716 (Flength): Report an error instead of overflowing an integer.
6717 (Fsafe_length): Return a float if the value is not representable
6718 as a fixnum. This shouldn't happen except in contrived situations.
6719 (Fnthcdr, Fsort): Don't assume list length fits in int.
6720 (Fcopy_sequence): Don't assume vector length fits in int.
6721
6722 * alloc.c: Check that resized vectors' lengths fit in fixnums.
6723 (header_size, word_size): New constants.
6724 (allocate_vectorlike): Don't check size overflow here.
6725 (allocate_vector): Check it here instead, since this is the only
6726 caller of allocate_vectorlike that could cause overflow.
6727 Check that the new vector's length is representable as a fixnum.
6728
6729 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
6730 The previous code was bogus. For example, next_almost_prime (32)
6731 returned 39, which is undesirable as it is a multiple of 3; and
6732 next_almost_prime (24) returned 25, which is a multiple of 5 so
6733 why was the code bothering to check for multiples of 7?
6734
6735 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
6736
6737 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
6738
6739 Variadic C functions now count arguments with ptrdiff_t.
6740 This partly undoes my 2011-03-30 change, which replaced int with size_t.
6741 Back then I didn't know that the Emacs coding style prefers signed int.
6742 Also, in the meantime I found a few more instances where arguments
6743 were being counted with int, which may truncate counts on 64-bit
6744 machines, or EMACS_INT, which may be unnecessarily wide.
6745 * lisp.h (struct Lisp_Subr.function.aMANY)
6746 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
6747 Arg counts are now ptrdiff_t, not size_t.
6748 All variadic functions and their callers changed accordingly.
6749 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
6750 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
6751 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
6752 * callint.c (Fcall_interactively): Check arg count for overflow,
6753 to avoid potential buffer overrun. Use signed char, not 'int',
6754 for 'varies' array, so that we needn't bother to check its size
6755 calculation for overflow.
6756 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
6757 * eval.c (apply_lambda):
6758 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
6759 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
6760 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
6761
6762 * callint.c (Fcall_interactively): Don't use index var as event count.
6763
6764 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
6765 * mem-limits.h (SIZE): Remove; no longer used.
6766
6767 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
6768
6769 Remove unnecessary casts.
6770 * xterm.c (x_term_init):
6771 * xfns.c (x_set_border_pixel):
6772 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
6773 These aren't needed now that we assume ANSI C.
6774
6775 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
6776 It's more likely to cause problems (due to unsigned overflow)
6777 than to cure them.
6778
6779 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
6780
6781 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
6782
6783 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
6784
6785 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
6786
6787 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
6788
6789 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
6790
6791 GLYPH_CODE_FACE returns EMACS_INT, not int.
6792 * dispextern.h (merge_faces):
6793 * xfaces.c (merge_faces):
6794 * xdisp.c (get_next_display_element, next_element_from_display_vector):
6795 Don't assume EMACS_INT fits in int.
6796
6797 * character.h (CHAR_VALID_P): Remove unused parameter.
6798 * fontset.c, lisp.h, xdisp.c: All uses changed.
6799
6800 * editfns.c (Ftranslate_region_internal): Omit redundant test.
6801
6802 * fns.c (concat): Minor tuning based on overflow analysis.
6803 This doesn't fix any bugs. Use int to hold character, instead
6804 of constantly refetching from Emacs object. Use XFASTINT, not
6805 XINT, for value known to be a character. Don't bother comparing
6806 a single byte to 0400, as it's always less.
6807
6808 * floatfns.c (Fexpt):
6809 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
6810
6811 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
6812 for characters.
6813
6814 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
6815
6816 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
6817 Without this fix, on a 64-bit host (aset S 0 4294967386) would
6818 incorrectly succeed when S was a string, because 4294967386 was
6819 truncated before it was used.
6820
6821 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
6822 Otherwise, an out-of-range integer could cause undefined behavior
6823 on a 64-bit host.
6824
6825 * composite.c: Use int, not EMACS_INT, for characters.
6826 (fill_gstring_body, composition_compute_stop_pos): Use int, not
6827 EMACS_INT, for values that are known to be in character range.
6828 This doesn't fix any bugs but is the usual style inside Emacs and
6829 may generate better code on 32-bit machines.
6830
6831 Make sure a 64-bit char is never passed to ENCODE_CHAR.
6832 This is for reasons similar to the recent CHAR_STRING fix.
6833 * charset.c (Fencode_char): Check that character arg is actually
6834 a character. Pass an int to ENCODE_CHAR.
6835 * charset.h (ENCODE_CHAR): Verify that the character argument is no
6836 wider than 'int', as a compile-time check to prevent future regressions
6837 in this area.
6838
6839 * character.c (char_string): Remove unnecessary casts.
6840
6841 Make sure a 64-bit char is never passed to CHAR_STRING.
6842 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
6843 by silently ignoring the top 32 bits, allowing some values
6844 that were far too large to be valid characters.
6845 * character.h: Include <verify.h>.
6846 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
6847 arguments are no wider than unsigned, as a compile-time check
6848 to prevent future regressions in this area.
6849 * data.c (Faset):
6850 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
6851 (Fsubst_char_in_region):
6852 * fns.c (concat):
6853 * xdisp.c (decode_mode_spec_coding):
6854 Adjust to CHAR_STRING's new requirement.
6855 * editfns.c (Finsert_char, Fsubst_char_in_region):
6856 * fns.c (concat): Check that character args are actually
6857 characters. Without this test, these functions did the wrong
6858 thing with wildly out-of-range values on 64-bit hosts.
6859
6860 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
6861 These casts should not be needed on 32-bit hosts, either.
6862 * keyboard.c (read_char):
6863 * lread.c (Fload): Remove casts to unsigned.
6864
6865 * lisp.h (UNSIGNED_CMP): New macro.
6866 This fixes comparison bugs on 64-bit hosts.
6867 (ASCII_CHAR_P): Use it.
6868 * casefiddle.c (casify_object):
6869 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
6870 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
6871 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
6872 * dispextern.h (FACE_FROM_ID):
6873 * keyboard.c (read_char): Use UNSIGNED_CMP.
6874
6875 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
6876 not to EMACS_INT, to avoid GCC warning.
6877
6878 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
6879
6880 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
6881 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
6882 isn't needed on 32-bit machines.
6883
6884 * buffer.c (Fgenerate_new_buffer_name):
6885 Use EMACS_INT for count, not int.
6886 (advance_to_char_boundary): Return EMACS_INT, not int.
6887
6888 * data.c (Qcompiled_function): Now static.
6889
6890 * window.c (window_body_lines): Now static.
6891
6892 * image.c (gif_load): Rename local to avoid shadowing.
6893
6894 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
6895 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
6896 * alloc.c (make_save_value): Integer argument is now of type
6897 ptrdiff_t, not int.
6898 (mark_object): Use ptrdiff_t, not int.
6899 * lisp.h (pD): New macro.
6900 * print.c (print_object): Use it.
6901
6902 * alloc.c: Use EMACS_INT, not int, to count objects.
6903 (total_conses, total_markers, total_symbols, total_vector_size)
6904 (total_free_conses, total_free_markers, total_free_symbols)
6905 (total_free_floats, total_floats, total_free_intervals)
6906 (total_intervals, total_strings, total_free_strings):
6907 Now EMACS_INT, not int. All uses changed.
6908 (Fgarbage_collect): Compute overall total using a double, so that
6909 integer overflow is less likely to be a problem. Check for overflow
6910 when converting back to an integer.
6911 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
6912 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
6913 These were 'int' variables that could overflow on 64-bit hosts;
6914 they were never used, so remove them instead of repairing them.
6915 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
6916 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
6917 Previously, this ceilinged at INT_MAX, but that doesn't work on
6918 64-bit machines.
6919 (allocate_pseudovector): Don't use EMACS_INT when int would do.
6920
6921 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
6922 (allocate_vectorlike): Check for ptrdiff_t overflow.
6923 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
6924 when a (possibly-narrower) signed value would do just as well.
6925 We prefer using signed arithmetic, to avoid comparison confusion.
6926
6927 * alloc.c: Catch some string size overflows that we were missing.
6928 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
6929 for convenience in STRING_BYTES_MAX.
6930 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
6931 The definition here is exact; the one in lisp.h was approximate.
6932 (allocate_string_data): Check for string overflow. This catches
6933 some instances we weren't catching before. Also, it catches
6934 size_t overflow on (unusual) hosts where SIZE_MAX <= min
6935 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
6936 and ptrdiff_t and EMACS_INT are both 64 bits.
6937
6938 * character.c, coding.c, doprnt.c, editfns.c, eval.c:

7363 * fileio.c (Finsert_file_contents):
7364 Likewise for BUF_BYTES_MAX.
7365

7381
7382 Minor fixes for signed vs unsigned integers.
7383 * character.h (MAYBE_UNIFY_CHAR):
7384 * charset.c (maybe_unify_char):
7385 * keyboard.c (read_char, reorder_modifiers):
7386 XINT -> XFASTINT, since the integer must be nonnegative.
7387 * ftfont.c (ftfont_spec_pattern):
7388 * keymap.c (access_keymap, silly_event_symbol_error):
7389 XUINT -> XFASTINT, since the integer must be nonnegative.
7390 (Fsingle_key_description, preferred_sequence_p): XUINT -> XINT,
7391 since it makes no difference and we prefer signed.
7392 * keyboard.c (record_char): Use XUINT when all the neighbors do.
7393 (access_keymap): NATNUMP -> INTEGERP, since the integer must be
7394 nonnegative.

7443
7444 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
7445 Do not assume that spare memory exists; that assumption is valid
7446 only if SYSTEM_MALLOC.
7447 (LARGE_REQUEST): New macro, so that the issue of large requests
7448 is separated from the issue of spare memory.
7449
7450 2011-06-05 Andreas Schwab <schwab@linux-m68k.org>
7451

7505 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
7506 (bidi_level_of_next_char, bidi_move_to_visually_next):
7507 Support character positions inside a run of characters covered by a
7508 display string.
7509 (bidi_paragraph_init, bidi_resolve_explicit_1)
7510 (bidi_level_of_next_char): Call bidi_fetch_char and
7511 bidi_fetch_char_advance instead of FETCH_CHAR and
7512 FETCH_CHAR_ADVANCE.

7514 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
7515 definitions.
7516 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
7517 instead of using explicit *_CHAR codes.
7518 (bidi_resolve_explicit, bidi_resolve_weak):
7519 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
7520 bidirectional text is supported only in multibyte buffers.
7521 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
7522 it to initialize the frame_window_p member of struct bidi_it.

7529 were just reseat()'ed to a new position.
7530
7531 * xdisp.c (set_cursor_from_row): Set start and stop points
7532 according to the row's direction when priming the loop that looks
7533 for the glyph on which to display cursor.
7534 (single_display_spec_intangible_p): Function deleted.
7535 (display_prop_intangible_p): Reimplement to call
7536 handle_display_spec instead of single_display_spec_intangible_p.
7537 Accept 3 additional arguments needed by handle_display_spec.
7538 This fixes incorrect cursor motion across display property with complex
7539 values: lists, `(when COND...)' forms, etc.
7540 (single_display_spec_string_p): Support property values that are
7541 lists with the argument STRING its top-level element.
7542 (display_prop_string_p): Fix the condition for processing a
7543 property that is a list to be consistent with handle_display_spec.
7544 (handle_display_spec): New function, refactored from the
7545 last portion of handle_display_prop.
7546 (compute_display_string_pos): Accept additional argument
7547 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
7548 value of a `display' property is a "replacing spec".
7549 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
7550 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
7551 the display property, but just return a value indicating whether
7552 the display property will replace the characters it covers.
7553 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
7554 frame_window_p members of struct bidi_it.
7555 (compute_display_string_pos, compute_display_string_end):
7556 New functions.

7560
7561 * keyboard.c (adjust_point_for_property): Adjust the call to
7562 display_prop_intangible_p to its new signature.
7563
7564 * dispextern.h (struct bidi_it): New member frame_window_p.
7565 (bidi_init_it): Update prototypes.
7566 (display_prop_intangible_p): Update prototype.
7567 (compute_display_string_pos, compute_display_string_end):

7578 All callers changed. (Bug#8762)
7579
7580 * gnutls.c: Use Emacs's memory allocators.
7581 Without this change, the gnutls library would invoke malloc etc.
7582 directly, which causes problems on non-SYNC_INPUT hosts, and which
7583 runs afoul of improving memory_full behavior. (Bug#8761)
7584 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
7585 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
7586 xfree instead of the default malloc, realloc, free.
7587 (Fgnutls_boot): No need to check for memory allocation failure,
7588 since xmalloc does that for us.
7589
7590 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
7591 * category.c (hash_get_category_set):

7606 * image.c (make_image, search_image_cache, lookup_image)
7607 (xpm_put_color_table_h):
7608 * lisp.h (struct Lisp_Hash_Table):
7609 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
7610 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
7611 for hashes and hash indexes, instead of 'unsigned' and 'int'.
7612 * alloc.c (allocate_vectorlike):
7613 Check for overflow in vector size calculations.
7614 * ccl.c (ccl_driver):
7615 Check for overflow when converting EMACS_INT to int.
7616 * fns.c, image.c: Remove unnecessary static decls that would otherwise
7617 need to be updated by these changes.
7618 * fns.c (make_hash_table, maybe_resize_hash_table):
7619 Check for integer overflow with large hash tables.
7620 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
7621 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
7622 (SXHASH_REDUCE): New macro.
7623 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
7624 Use it instead of discarding useful hash info with large hash values.
7625 (sxhash_float): New function.
7626 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
7627 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
7628 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
7629 Rewrite to use FIXNUM_BITS, as this simplifies things.
7630 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
7631 Adjust signatures to match updated version of code.
7632 (consing_since_gc): Now EMACS_INT, since a single hash table can
7633 use more than INT_MAX bytes.
7634

7681
7682 Make it possible to run ./temacs.
7683
7684 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
7685 syms_of_callproc does the same thing. Remove test for

7763 Check for serial numbers out of range. Decode any serial number
7764 that was so large that it became a float. (Bug#8722)
7765
7766 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
7767 (Fdbus_call_method, Fdbus_call_method_asynchronously):
7768 Use XFASTINT rather than XUINT when numbers are nonnegative.
7769 (xd_append_arg, Fdbus_method_return_internal):
7770 (Fdbus_method_error_internal): Likewise. Also, for unsigned
7771 arguments, check that Lisp number is nonnegative, rather than
7772 silently wrapping negative numbers around. (Bug#8722)
7773 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
7774 (Bug#8722)
7775
7776 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
7777
7778 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
7779
7780 ccl: Add integer overflow checks.
7781 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
7782 (IN_INT_RANGE): New macros.
7783 (ccl_driver): Use them to check for integer overflow when
7784 decoding a CCL program. Many of the new checks are whether XINT (x)
7785 fits in int; it doesn't always, on 64-bit hosts. The new version
7786 doesn't catch all possible integer overflows, but it's an
7787 improvement. (Bug#8719)
7788
7789 * alloc.c (make_event_array): Use XINT, not XUINT.
7790 There's no need for unsigned here.
7791
7792 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
7793 This follows up to the 2011-05-06 change that substituted uintptr_t
7794 for EMACS_INT. This case wasn't caught back then.
7795
7796 Rework Fformat to avoid integer overflow issues.
7797 * editfns.c: Include <float.h> unconditionally, as it's everywhere
7798 now (part of C89). Include <verify.h>.
7799 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
7800 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
7801 (Fformat): Avoid the prepass trying to compute sizes; it was only
7802 approximate and thus did not catch overflow reliably. Instead, walk
7803 through the format just once, formatting and computing sizes as we go,
7804 checking for integer overflow at every step, and allocating a larger
7805 buffer as needed. Keep track separately whether the format is
7806 multibyte. Keep only the most-recently calculated precision, rather
7807 than them all. Record whether each argument has been converted to
7808 string. Use EMACS_INT, not int, for byte and char and arg counts.
7809 Support field widths and precisions larger than INT_MAX. Avoid
7810 sprintf's undefined behavior with conversion specifications such as %#d
7811 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
7812 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
7813 formatting out-of-range floating point numbers with int
7814 formats. (Bug#8668)
7815
7816 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
7817
7818 * data.c: Avoid integer truncation in expressions involving floats.
7819 * data.c: Include <intprops.h>.
7820 (arith_driver): When there's an integer overflow in an expression
7821 involving floating point, convert the integers to floating point
7822 so that the resulting value does not suffer from catastrophic
7823 integer truncation. For example, on a 64-bit host (* 4
7824 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
7825 Do not rely on undefined behavior after integer overflow.
7826
7827 merge count_size_as_multibyte, parse_str_to_multibyte
7828 * character.c, character.h (count_size_as_multibyte):
7829 Rename from parse_str_to_multibyte; all uses changed.
7830 Check for integer overflow.
7831 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
7832 since it's now a duplicate of the other. This is more of
7833 a character than a buffer op, so better that it's in character.c.
7834 * fns.c, print.c: Adjust to above changes.
7835
7836 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
7837
7838 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
7839
7840 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
7841
7842 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
7843 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
7844 (x_clipboard_manager_save): Now static.
7845 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
7846
7847 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
7848 (crypto_hash_function): Now static.
7849 Fix pointer signedness problems. Avoid unnecessary initializations.
7850
7851 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
7852
7853 * termhooks.h (Vselection_alist): Make it terminal-local.
7854
7855 * terminal.c (create_terminal): Initialize it.
7856
7857 * xselect.c: Support for clipboard managers.
7858 (Vselection_alist): Move to termhooks.h as terminal-local var.
7859 (LOCAL_SELECTION): New macro.
7860 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
7861 (symbol_to_x_atom): Remove gratuitous arg.
7862 (x_handle_selection_request, lisp_data_to_selection_data)
7863 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
7864 (x_own_selection, x_get_local_selection, x_convert_selection):
7865 New arg, specifying work frame. Use terminal-local Vselection_alist.
7866 (some_frame_on_display): Delete unused function.
7867 (Fx_own_selection_internal, Fx_get_selection_internal)
7868 (Fx_disown_selection_internal, Fx_selection_owner_p)
7869 (Fx_selection_exists_p): New optional frame arg.
7870 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
7871 (x_handle_selection_clear): Don't treat other terminals with the
7872 same keyboard specially. Use the terminal-local Vselection_alist.
7873 (x_clear_frame_selections): Use Frun_hook_with_args.
7874
7875 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
7876
7877 * xterm.h: Add support for those atoms.
7878
7879 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
7880
7881 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
7882 (converted_selections, conversion_fail_tag): New global variables.
7883 (x_selection_request_lisp_error): Free the above.
7884 (x_get_local_selection): Remove unnecessary code.
7885 (x_reply_selection_request): Args changed; handle arbitrary array
7886 of converted selections stored in converted_selections.
7887 Separate the XChangeProperty and SelectionNotify steps.
7888 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
7889 (x_convert_selection): New function.
7890 (x_handle_selection_event): Simplify.
7891 (x_get_foreign_selection): Don't ignore incoming requests while
7892 waiting for an answer; this will fail when we implement
7893 SAVE_TARGETS, and seems unnecessary anyway.
7894 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
7895 (Vx_sent_selection_functions): Doc fix.
7896
7897 2011-05-26 Leo Liu <sdl.web@gmail.com>
7898
7899 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
7900
7901 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
7902
7903 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
7904
7905 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
7906 for fringe update if it has periodic bitmap.
7907 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
7908 and fringe_bitmap_periodic_p.
7909
7910 * fringe.c (get_fringe_bitmap_data): New function.
7911 (draw_fringe_bitmap_1, update_window_fringes): Use it.
7912 (update_window_fringes): Record periodicity of fringe bitmap in glyph
7913 row. Mark glyph row for fringe update if periodicity changed.
7914
7915 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
7916 for fringe update unless it has periodic bitmap.
7917
7918 2011-05-25 Kenichi Handa <handa@m17n.org>
7919
7920 * xdisp.c (get_next_display_element): Set correct it->face_id for
7921 a static composition.
7922
7923 2011-05-24 Leo Liu <sdl.web@gmail.com>
7924
7925 * deps.mk (fns.o):
7926 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
7927
7928 * fns.c (crypto_hash_function, Fsha1): New function.
7929 (Fmd5): Use crypto_hash_function.
7930 (syms_of_fns): Add Ssha1.
7931
7932 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
7933
7934 * gnutls.c: Remove unused macros.
7935 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
7936 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
7937 Remove macros that are defined and never used.
7938 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
7939
7940 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
7941
7942 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
7943 (Fx_get_selection_internal): Minor cleanup.
7944 (Fx_own_selection_internal): Rename arguments for consistency with
7945 select.el.
7946
7947 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
7948
7949 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
7950
7951 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
7952
7953 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
7954
7955 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
7956
7957 * dispnew.c (scrolling_window): Don't exclude the case that the
7958 last enabled row in the desired matrix touches the bottom boundary.
7959
7960 2011-05-21 Glenn Morris <rgm@gnu.org>
7961
7962 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
7963 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
7964 and add some more files.
7965
7966 2011-05-20 Eli Zaretskii <eliz@gnu.org>
7967
7968 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
7969 report_file_error introduced by the change from 2011-05-07.
7970
7971 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
7972
7973 * systime.h (Time): Define only if emacs is defined.
7974 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
7975 where the include path doesn't have X11/X.h by default. See
7976 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
7977
7978 2011-05-20 Kenichi Handa <handa@m17n.org>
7979
7980 * composite.c (find_automatic_composition): Fix previous change.
7981
7982 2011-05-20 Glenn Morris <rgm@gnu.org>
7983
7984 * lisp.mk: New file, split from Makefile.in.
7985 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
7986 (shortlisp): Remove.
7987 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
7988
7989 2011-05-19 Glenn Morris <rgm@gnu.org>
7990
7991 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
7992 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
7993 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
7994 (lisp): Set the order to that of loadup.el.
7995 (shortlisp): Make it a copy of $lisp.
7996 (SOME_MACHINE_LISP): Remove.
7997 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
7998 Use just $shortlisp, not $SOME_MACHINE_LISP too.
7999
8000 2011-05-18 Kenichi Handa <handa@m17n.org>
8001
8002 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
8003 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
8004 (find_automatic_composition): Mostly rewrite for efficiency.
8005
8006 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
8007
8008 * makefile.w32-in: Update dependencies.
8009
8010 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
8011
8012 * menu.c: Include limits.h (fixes the MS-Windows build broken by
8013 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
8014
8015 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
8016
8017 Fix some integer overflow issues, such as string length overflow.
8018
8019 * insdel.c (count_size_as_multibyte): Check for string overflow.
8020
8021 * character.c (lisp_string_width): Check for string overflow.
8022 Use EMACS_INT, not int, for string indexes and lengths; in
8023 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
8024 the resulting string length overflows an EMACS_INT; instead,
8025 report a string overflow if no precision given. When checking for
8026 precision exhaustion, use a check that cannot possibly have
8027 integer overflow. (Bug#8675)
8028 * character.h (lisp_string_width): Adjust to new signature.
8029
8030 * alloc.c (string_overflow): New function.
8031 (Fmake_string): Use it. This doesn't change behavior, but saves
8032 a few bytes and will simplify future changes.
8033 * character.c (string_escape_byte8): Likewise.
8034 * lisp.h (string_overflow): New decl.
8035
8036 Fixups, following up to the user-interface timestamp change.
8037 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
8038 for UI timestamps, instead of unsigned long.
8039 * msdos.c (mouse_get_pos): Likewise.
8040 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
8041 * w32gui.h (Time): Define by including "systime.h" rather than by
8042 declaring it ourselves. (Bug#8664)
8043
8044 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
8045 * image.c (clear_image_cache): Likewise.
8046
8047 * term.c (term_mouse_position): Don't assume time_t wraparound.
8048
8049 Be more systematic about user-interface timestamps.
8050 Before, the code sometimes used 'Time', sometimes 'unsigned long',
8051 and sometimes 'EMACS_UINT', to represent these timestamps.
8052 This change causes it to use 'Time' uniformly, as that's what X uses.
8053 This makes the code easier to follow, and makes it easier to catch
8054 integer overflow bugs such as Bug#8664.
8055 * frame.c (Fmouse_position, Fmouse_pixel_position):
8056 Use Time, not unsigned long, for user-interface timestamps.
8057 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
8058 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
8059 * keyboard.h (last_event_timestamp): Likewise.
8060 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
8061 * menu.h (xmenu_show): Likewise.
8062 * term.c (term_mouse_position): Likewise.
8063 * termhooks.h (struct input_event.timestamp): Likewise.
8064 (struct terminal.mouse_position_hook): Likewise.
8065 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
8066 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
8067 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
8068 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
8069 what it was before.
8070 * menu.h, termhooks.h: Include "systime.h", for Time.
8071
8072 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
8073 Don't assume that the difference between two unsigned long values
8074 can fit into an integer. At this point, we know button_down_time
8075 <= event->timestamp, so the difference must be nonnegative, so
8076 there's no need to cast the result if double-click-time is
8077 nonnegative, as it should be; check that it's nonnegative, just in
8078 case. This bug is triggered when events are more than 2**31 ms
8079 apart (about 25 days). (Bug#8664)
8080
8081 * xselect.c (last_event_timestamp): Remove duplicate decl.
8082 (x_own_selection): Remove needless cast to unsigned long.
8083
8084 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
8085 that always fit in int. Use a sentinel instead of a counter, to
8086 avoid a temp and to allay GCC's concerns about possible int overflow.
8087 * frame.h (struct frame): Use int for menu_bar_items_used
8088 instead of EMACS_INT, since it always fits in int.
8089
8090 * menu.c (grow_menu_items): Check for int overflow.
8091
8092 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
8093
8094 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
8095 Before, the code was not consistent. These values cannot exceed
8096 2**31 - 1 so there's no need to make them unsigned.
8097 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
8098 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
8099 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
8100 as modifiers.
8101 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
8102
8103 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
8104 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
8105 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
8106 presumably because the widths might not match.
8107
8108 * window.c (size_window): Avoid needless test at loop start.
8109
8110 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
8111
8112 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
8113
8114 2011-05-12 Drew Adams <drew.adams@oracle.com>
8115
8116 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
8117
8118 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
8119
8120 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
8121 `width' to `bar_area_x' and `bar_area_width', respectively.
8122 (x_scroll_run): Take account of fringe background extension.
8123
8124 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
8125 Rename local vars `left' and `width' to `bar_area_x' and
8126 `bar_area_width', respectively.
8127 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
8128 background extension.
8129
8130 2011-05-10 Jim Meyering <meyering@redhat.com>
8131
8132 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
8133
8134 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
8135
8136 * image.c (Finit_image_library): Return t for built-in image types,
8137 like pbm and xbm. (Bug#8640)
8138
8139 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
8140
8141 * w32menu.c (set_frame_menubar): Fix submenu allocation.
8142
8143 2011-05-07 Eli Zaretskii <eliz@gnu.org>
8144
8145 * w32console.c (Fset_screen_color): Doc fix.
8146 (Fget_screen_color): New function.
8147 (syms_of_ntterm): Defsubr it.
8148
8149 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
8150 unlink the temporary file if Fcall_process didn't create it in the
8151 first place.
8152 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
8153 child process will be redirected to a file specified with `:file'.
8154 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
8155 cue to call_process_cleanup not to close that handle.
8156
8157 2011-05-07 Ben Key <bkey76@gmail.com>
8158
8159 * makefile.w32-in: The bootstrap-temacs rule now makes use of
8160 one of two shell specific rules, either bootstrap-temacs-CMD or
8161 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
8162 to the previous implementation of the bootstrap-temacs rule.
8163 The bootstrap-temacs-CMD rule is similar to the previous
8164 implementation of the bootstrap-temacs rule except that it
8165 makes use of the ESC_CFLAGS variable instead of the CFLAGS
8166 variable.
8167
8168 These changes, along with some changes to nt/configure.bat,
8169 nt/gmake.defs, and nt/nmake.defs, are required to extend my
8170 earlier fix to add support for --cflags and --ldflags options
8171 that include quotes so that it works whether make uses cmd or
8172 sh as the shell.
8173
8174 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
8175
8176 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
8177 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
8178 is a constant.
8179 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
8180 a string. Handle both cases.
8181 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
8182 (Fdbus_register_method): Use Qinvalid_function.
8183
8184 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
8185
8186 * makefile.w32-in: Update dependencies.
8187 (LISP_H): Add inttypes.h and stdin.h.
8188 (PROCESS_H): Add unistd.h.
8189
8190 2011-05-06 Eli Zaretskii <eliz@gnu.org>
8191
8192 * lread.c: Include limits.h (fixes the MS-Windows build broken by
8193 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
8194
8195 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
8196
8197 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
8198
8199 * term.c (vfatal): Remove stray call to va_end.
8200 It's not needed and the C Standard doesn't allow it here anyway.
8201
8202 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
8203 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
8204
8205 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
8206 bytes.
8207
8208 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
8209
8210 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
8211
8212 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
8213
8214 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
8215
8216 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
8217
8218 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
8219 * charset.c (Fdefine_charset_internal): Don't initialize
8220 charset.code_space[15]. The value was garbage, on hosts with
8221 32-bit int (Bug#8600).
8222
8223 * lread.c (read_integer): Be more consistent with string-to-number.
8224 Use string_to_number to do the actual conversion; this avoids
8225 rounding errors and fixes some other screwups. Without this fix,
8226 for example, #x1fffffffffffffff was misread as -2305843009213693952.
8227 (digit_to_number): Move earlier, for benefit of read_integer.
8228 Return -1 if the digit is out of range for the base, -2 if it is
8229 not a digit in any supported base. (Bug#8602)
8230
8231 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
8232
8233 * dispnew.c (scrolling_window): Return 1 if we scrolled,
8234 to match comment at start of function. This also removes a
8235 GCC warning about overflow in a 32+64-bit port.
8236
8237 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
8238
8239 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
8240 Reported by Stefan Monnier in
8241 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
8242 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
8243 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
8244
8245 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
8246 (EMACS_UINTPTR): Likewise, with uintptr_t.
8247
8248 * lisp.h: Prefer 64-bit EMACS_INT if available.
8249 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
8250 on 32-bit hosts that have 64-bit int, so that they can access
8251 large files.
8252 However, temporarily disable this change unless the temporary
8253 symbol WIDE_EMACS_INT is defined.
8254
8255 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
8256
8257 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
8258 This removes an assumption that EMACS_INT and long are the same
8259 width as pointers. The assumption is true for Emacs porting targets
8260 now, but we want to make other targets possible.
8261 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
8262 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
8263 In the rest of the code, change types of integers that hold casted
8264 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
8265 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
8266 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
8267 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
8268 No need to cast type when ORing.
8269 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
8270 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
8271 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
8272 assume EMACS_INT is the same width as char *.
8273 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
8274 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
8275 Remove no-longer-needed casts.
8276 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
8277 (xg_tool_bar_help_callback, xg_make_tool_item):
8278 Use EMACS_INTPTR to hold an integer
8279 that will be cast to void *; this can avoid a GCC warning
8280 if EMACS_INT is not the same width as void *.
8281 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
8282 * xdisp.c (display_echo_area_1, resize_mini_window_1):
8283 (current_message_1, set_message_1):
8284 Use a local to convert to proper width without a cast.
8285 * xmenu.c (dialog_selection_callback): Likewise.
8286
8287 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
8288 Also, don't assume VALBITS / RAND_BITS is less than 5,
8289 and don't rely on undefined behavior when shifting a 1 left into
8290 the sign bit.
8291 * lisp.h (get_random): Change signature to match.
8292
8293 * lread.c (hash_string): Use size_t, not int, for hash computation.
8294 Normally we prefer signed values; but hashing is special, because
8295 it's better to use unsigned division on hash table sizes so that
8296 the remainder is nonnegative. Also, size_t is the natural width
8297 for hashing into memory. The previous code used 'int', which doesn't
8298 retain enough info to hash well into very large tables.
8299 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
8300
8301 * dbusbind.c: Don't possibly lose pointer info when converting.
8302 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
8303 Use XPNTR rather than XHASH, so that the high-order bits of
8304 the pointer aren't lost when converting through void *.
8305
8306 * eval.c (Fautoload): Don't double-shift a pointer.
8307
8308 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
8309
8310 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
8311
8312 * gnutls.c (DEF_GNUTLS_FN):
8313 * image.c (DEF_IMGLIB_FN): Make function pointers static.
8314
8315 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
8316
8317 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
8318 marker. (Bug#8610)
8319
8320 2011-05-05 Eli Zaretskii <eliz@gnu.org>
8321

8342 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
8343 Remove unused parameter `fildes'.
8344 * process.c (read_process_output, send_process): Don't pass it.
8345
8346 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
8347
8348 Fix previous change: the library cache is defined in w32.c.
8349 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
8350 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
8351
8352 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
8353
8354 Implement dynamic loading of GnuTLS on Windows.
8355

8358 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
8359 Declare.

8388 Initialize and staticpro them.
8389 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
8390
8391 * process.c: Include lisp.h before w32.h, not after.
8392 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
8393 instead of gnutls_record_check_pending.

8421 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
8422 (Qgnutls_bootprop_callbacks_verify): Make static.
8423

8427
8428 * sysdep.c (wait_for_termination_1): Make static.
8429 (wait_for_termination, interruptible_wait_for_termination):
8430 Move after wait_for_termination_1.
8431
8432 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
8433
8434 * sysdep.c (interruptible_wait_for_termination): New function
8435 which is like wait_for_termination, but allows keyboard
8436 interruptions.
8437
8438 * callproc.c (Fcall_process): Add (:file "file") as an option for
8439 the STDOUT buffer.
8440 (Fcall_process_region): Ditto.

8458 will grow beyond MOST_POSITIVE_FIXNUM.
8459 (decode_coding_emacs_mule): Abort if there isn't enough place in
8460 charbuf for the composition carryover bytes. Reserve an extra
8461 space for up to 2 characters produced in a loop.
8462 (decode_coding_iso_2022): Abort if there isn't enough place in
8463 charbuf for the composition carryover bytes.
8464

8512
8513 2011-04-27 Eli Zaretskii <eliz@gnu.org>
8514
8515 Improve `doprnt' and its usage. (Bug#8545)
8516 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
8517 `format_end'. Remove support for %l as a conversion specifier.
8518 Don't use xrealloc. Improve diagnostics when the %l size modifier
8519 is used. Update the commentary.
8520
8521 * eval.c (verror): Simplify calculation of size_t.
8522
8523 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
8524 messages.
8525
8526 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
8527
8528 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
8529 change.
8530
8531 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
8532
8533 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
8534 This makes this file independent of the recent pseudovector change.
8535
8536 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
8537
8538 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
8539
8540 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
8541 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
8542 Remove unused local.
8543 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
8544
8545 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
8546 GCC 4.6.0 optimizes based on type-based alias analysis.
8547 For example, if b is of type struct buffer * and v of type struct
8548 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
8549 != &v->size, and therefore "v->size = 1; b->size = 2; return
8550 v->size;" must therefore return 1. This assumption is incorrect
8551 for Emacs, since it type-puns struct Lisp_Vector * with many other
8552 types. To fix this problem, this patch adds a new type struct
8553 vectorlike_header that documents the constraints on layout of vectors
8554 and pseudovectors, and helps optimizing compilers not get fooled
8555 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
8556 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
8557 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
8558 the size member.
8559 (XSETPVECTYPE): Rewrite in terms of new macro.
8560 (XSETPVECTYPESIZE): New macro, specifying both type and size.
8561 This is a bit clearer, and further avoids the possibility of
8562 undesirable aliasing.
8563 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
8564 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
8565 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
8566 since Lisp_Subr is a special case (no "next" field).
8567 (ASIZE): Now uses header.size rather than size.
8568 All previous uses of XVECTOR (foo)->size replaced to use this macro,
8569 to avoid the hassle of writing XVECTOR (foo)->header.size.
8570 (struct vectorlike_header): New type.
8571 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
8572 object, to help avoid aliasing.
8573 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
8574 (SUBRP): Likewise, since Lisp_Subr is a special case.
8575 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
8576 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
8577 (struct Lisp_Hash_Table): Combine first two members into a single
8578 struct vectorlike_header member. All uses of "size" and "next" members
8579 changed to be "header.size" and "header.next".
8580 * buffer.h (struct buffer): Likewise.
8581 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
8582 * frame.h (struct frame): Likewise.
8583 * process.h (struct Lisp_Process): Likewise.
8584 * termhooks.h (struct terminal): Likewise.
8585 * window.c (struct save_window_data, struct saved_window): Likewise.
8586 * window.h (struct window): Likewise.
8587 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
8588 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
8589 * buffer.c (init_buffer_once): Likewise.
8590 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
8591 special case.
8592 * process.c (Fformat_network_address): Use local var for size,
8593 for brevity.
8594
8595 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
8596
8597 Make the Lisp reader and string-to-float more consistent (Bug#8525)
8598 * data.c (atof): Remove decl; no longer used or needed.
8599 (digit_to_number): Move to lread.c.
8600 (Fstring_to_number): Use new string_to_number function, to be
8601 consistent with how the Lisp reader treats infinities and NaNs.
8602 Do not assume that floating-point numbers represent EMACS_INT
8603 without losing information; this is not true on most 64-bit hosts.
8604 Avoid double-rounding errors, by insisting on integers when
8605 parsing non-base-10 numbers, as the documentation specifies.
8606 * lisp.h (string_to_number): New decl, replacing ...
8607 (isfloat_string): Remove.
8608 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
8609 (read1): Do not accept +. and -. as integers; this
8610 appears to have been a coding error. Similarly, do not accept
8611 strings like +-1e0 as floating point numbers. Do not report
8612 overflow for integer overflows unless the base is not 10 which
8613 means we have no simple and reliable way to continue.
8614 Break out the floating-point parsing into a new
8615 function string_to_number, so that Fstring_to_number parses
8616 floating point numbers consistently with the Lisp reader.
8617 (digit_to_number): Move here from data.c. Make it static inline.
8618 (E_CHAR, EXP_INT): Remove, replacing with ...
8619 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
8620 (string_to_number): New function, replacing isfloat_string.
8621 This function checks for valid syntax and produces the resulting
8622 Lisp float number too. Rework it so that string-to-number
8623 no longer mishandles examples like "1.0e+". Use strtoumax,
8624 so that overflow for non-base-10 numbers is reported only when
8625 there's no portable and simple way to convert to floating point.
8626
8627 * textprop.c (set_text_properties_1): Rewrite for clarity,
8628 and to avoid GCC warning about integer overflow.
8629
8630 * intervals.h (struct interval): Use EMACS_INT for members
8631 where EMACS_UINT might cause problems. See
8632 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
8633 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
8634 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
8635 All uses changed.
8636 (offset_intervals): Tell GCC not to worry about length overflow
8637 when negating a negative length.
8638
8639 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
8640 (overrun_check_free): Likewise.
8641
8642 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
8643 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
8644 word size.
8645
8646 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
8647 (gnutls_make_error): Rename local to avoid shadowing.
8648 (gnutls_emacs_global_deinit): ifdef out; not used.
8649 (Fgnutls_boot): Use const for pointer to readonly storage.
8650 Comment out unused local. Fix pointer signedness problems.
8651
8652 * lread.c (openp): Don't stuff size_t into an 'int'.
8653 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
8654 about possible signed overflow.
8655
8656 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
8657 (GDK_KEY_g): Don't define if already defined.
8658 (xg_prepare_tooltip): Avoid pointer signedness problem.
8659 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
8660
8661 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
8662 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
8663
8664 * xfns.c (Fx_window_property): Simplify a bit,
8665 to make a bit faster and to avoid GCC 4.6.0 warning.
8666 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
8667
8668 * fns.c (internal_equal): Don't assume size_t fits in int.
8669
8670 * alloc.c (compact_small_strings): Tighten assertion a little.
8671
8672 Replace pEd with more-general pI, and fix some printf arg casts.
8673 * lisp.h (pI): New macro, generalizing old pEd macro to other
8674 conversion specifiers. For example, use "...%"pI"d..." rather
8675 than "...%"pEd"...".
8676 (pEd): Remove. All uses replaced with similar uses of pI.
8677 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
8678 * alloc.c (check_pure_size): Don't overflow by converting size to int.
8679 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
8680 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
8681 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
8682 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
8683 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
8684 64-bit hosts.
8685 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
8686 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
8687 * print.c (safe_debug_print, print_object): Likewise.
8688 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
8689 to int.
8690 Use pI instead of if-then-else-abort. Use %p to avoid casts,
8691 avoiding the 0 flag, which is not portable.
8692 * process.c (Fmake_network_process): Use pI to avoid cast.
8693 * region-cache.c (pp_cache): Likewise.
8694 * xdisp.c (decode_mode_spec): Likewise.
8695 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
8696 behavior on 64-bit hosts with printf arg.
8697 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
8698 (x_stop_queuing_selection_requests): Likewise.
8699 (x_get_window_property): Don't truncate byte count to an 'int'
8700 when tracing.
8701
8702 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
8703 here, since it parses constructs like leading '-' and spaces,
8704 which are not wanted; and it overflows with large numbers.
8705 Instead, simply match F[0-9]+, which is what is wanted anyway.
8706
8707 * alloc.c: Remove unportable assumptions about struct layout.
8708 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
8709 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
8710 (allocate_vectorlike, make_pure_vector): Use the new macros,
8711 plus offsetof, to remove unportable assumptions about struct layout.
8712 These assumptions hold on all porting targets that I know of, but
8713 they are not guaranteed, they're easy to remove, and removing them
8714 makes further changes easier.
8715
8716 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
8717 This doesn't fix a bug but makes the code clearer.
8718 (string_overrun_cookie): Now const. Use initializers that
8719 don't formally overflow signed char, to avoid warnings.
8720 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
8721 can cause Emacs to crash when string overrun checking is enabled.
8722 (allocate_buffer): Don't assume sizeof (struct buffer) is a
8723 multiple of sizeof (EMACS_INT); it need not be, if
8724 alignof(EMACS_INT) < sizeof (EMACS_INT).
8725 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
8726
8727 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
8728
8729 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
8730

8732
8733 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
8734 supposed to be handshaking. (Bug#8556)
8735 Reported by Paul Eggert <eggert@cs.ucla.edu>.
8736
8737 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
8738
8739 * lisp.h (Qdebug): List symbol.
8740 * eval.c (Qdebug): Restore global linkage.
8741 * keyboard.c (debug-on-event): New variable.
8742 (handle_user_signal): Break into debugger when debug-on-event
8743 matches the current signal symbol.
8744
8745 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
8746
8747 * alloc.c (check_sblock, check_string_bytes)
8748 (check_string_free_list): Convert to standard C.
8749
8750 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
8751
8752 * w32.c (emacs_gnutls_push): Fix typo.
8753
8754 2011-04-25 Eli Zaretskii <eliz@gnu.org>
8755
8756 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
8757 "cast to pointer from integer of different size".
8758
8759 Improve doprnt and its use in verror. (Bug#8545)
8760 * doprnt.c (doprnt): Document the set of format control sequences
8761 supported by the function. Use SAFE_ALLOCA instead of always
8762 using `alloca'.
8763
8764 * eval.c (verror): Don't limit the buffer size at size_max-1, that
8765 is one byte too soon. Don't use xrealloc; instead xfree and
8766 xmalloc anew.
8767
8768 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
8769
8770 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
8771 callbacks stage.
8772
8773 * gnutls.c: Renamed global_initialized to
8774 gnutls_global_initialized. Added internals for the
8775 :verify-hostname-error, :verify-error, and :verify-flags
8776 parameters of `gnutls-boot' and documented those parameters in the
8777 docstring. Start callback support.
8778 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
8779 unless a fatal error occurred. Call gnutls_alert_send_appropriate
8780 on error. Return error code.
8781 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
8782 (emacs_gnutls_read): Likewise.
8783 (Fgnutls_boot): Return handshake error code.

8806 display_replaced_before_p argument into display_replaced_p, to
8807 make it consistent with the commentary. Fix typos in the
8808 commentary.
8809
8810 * textprop.c (syms_of_textprop): Remove dead code.
8811 (copy_text_properties): Delete obsolete commentary about an

8816 to changes in oldXMenu/XMenu.h from 2011-04-16.
8817 <menu_help_message, prev_menu_help_message>: Constify.

8832 * doprnt.c (doprnt): Improve commentary.
8833
8834 * term.c (init_tty) [MSDOS]: Fix 1st argument to maybe_fatal.
8835
8836 * Makefile.in (TAGS): Depend on $(M_FILE) and $(S_FILE), and scan
8837 them with etags.
8838
8839 * makefile.w32-in (globals.h): Add a dummy recipe, to make any
8840 changes in globals.h immediately force recompilation.
8841 (TAGS): Depend on $(CURDIR)/m/intel386.h and
8842 $(CURDIR)/s/ms-w32.h.
8843 (TAGS-gmake): Scan $(CURDIR)/m/intel386.h and $(CURDIR)/s/ms-w32.h.
8844
8845 * character.c (Fchar_direction): Function deleted.
8846 (syms_of_character): Don't defsubr it.
8847 <char-direction-table>: Deleted.
8848
8849 2011-04-23 Eli Zaretskii <eliz@gnu.org>
8850
8851 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
8852 * doprnt.c: Include limits.h.
8853 (SIZE_MAX): New macro.
8854 (doprnt): Return a size_t value. 2nd arg is now size_t.
8855 Many local variables are now size_t instead of int or unsigned.
8856 Improve overflow protection. Support `l' modifier for integer
8857 conversions. Support %l conversion. Don't assume an EMACS_INT
8858 argument for integer conversions and for %c.
8859
8860 * lisp.h (doprnt): Restore prototype.
8861
8862 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on

8869
8870 * eval.c (internal_lisp_condition_case): Include the handler
8871 representation in the error message.
8872 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
8873 when breaking from the loop.
8874
8875 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
8876
8877 * callint.c (Fcall_interactively): When displaying error message
8878 about invalid control letter, pass the character's codepoint, not
8879 a pointer to its multibyte form. Improve display of the character
8880 in octal and display also its hex code.
8881
8882 * character.c (char_string): Use %x to display the (unsigned)
8883 codepoint of an invalid character, to avoid displaying a bogus
8884 negative value.
8885
8886 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
8887 `error', not SYMBOL_NAME itself.
8888

8890 character arguments to `error'.
8891
8892 * charset.c (check_iso_charset_parameter): Fix incorrect argument
8893 to `error' in error message about FINAL_CHAR argument. Make sure
8894 FINAL_CHAR is a character, and use %c when it is passed as
8895 argument to `error'.
8896

8939 * dispextern.h (FACE_SUITABLE_FOR_ASCII_CHAR_P): Add missing
8940 definition for no-X builds.
8941

8955
8956 * data.c (arith_error): Mark with NO_RETURN if it doesn't return.
8957
8958 * alloc.c (bytes_used_when_full, SPARE_MEMORY, BYTES_USED):
8959 Define only if needed.
8960
8961 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
8962 by pacifying GCC about it. Maybe it's time to retire it?
8963 * xfaces.c (USG, __TIMEVAL__): Likewise.
8964
8965 * dispextern.h (struct redisplay_interface): Rename param
8966 to avoid shadowing.

8974 it.
8975
8976 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,

9083
9084 * nsfont.m: Fixed bugs in ns_get_family and
9085 ns_descriptor_to_entity that were caused by using free to
9086 deallocate memory blocks that were allocated by xmalloc (via
9087 xstrdup). This caused Emacs to crash when compiled with
9088 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
9089 --enable-checking=xmallocoverrun). xfree is now used to
9090 deallocate these memory blocks.

9441 * buffer.c (buffer_count): Remove unused var.
9442
9443 * bidi.c (bidi_dump_cached_states): Mark as externally visible,
9444 so that it's not optimized away.
9445 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
9446 * dispextern.h (bidi_dump_cached_states): Remove, since it's
9447 exported only to the debugger.
9448
9449 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
9450 * atimer.h (run_all_atimers): Remove; not exported.
9451
9452 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
9453 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
9454 was inaccessible from Lisp.
9455 (merge_font_spec): Likewise, renaming from Fmerge_font_spec.
9456 * font.c, font.h, fontset.c, xfaces.c, xfont.c: Change all uses.
9457
9458 alloc.c: Import and export fewer symbols, and remove unused items.
9459 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
9460 is defined.
9461 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
9462 it's not optimized away by whole-program optimization.
9463 (message_enable_multibyte, free_misc): Remove.
9464 (catchlist, handlerlist, mark_backtrace):
9465 Declare only if BYTE_MARK_STACK.

9476 * xdisp.c (message_enable_multibyte): Now static.
9477
9478 Declare Lisp_Object Q* variables to be 'static' if not exported.
9479 This makes it easier for human readers (and static analyzers)
9480 to see whether these variables are used from other modules.
9481 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
9482 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
9483 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:

9491 Remove decls of unexported vars.
9492 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
9493
9494 * lisp.h (DEFINE_FUNC): Make sname 'static'.
9495
9496 Make Emacs functions such as Fatom 'static' by default.
9497 This makes it easier for human readers (and static analyzers)
9498 to see whether these functions can be called from other modules.
9499 DEFUN now defines a static function. To make the function external
9500 so that it can be used in other C modules, use the new macro DEFUE.
9501 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
9502 (Finit_image_library):
9503 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
9504 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
9505 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
9506 Remove decls, since these functions are now static.
9507 (Funintern, Fget_internal_run_time): New decls, since these functions
9508 were already external.
9509
9510 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:

9517 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
9518 Mark functions with DEFUE instead of DEFUN,
9519 if they are used in other modules.
9520 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
9521 decls for now-static functions.
9522 * buffer.h (Fdelete_overlay): Remove decl.
9523 * callproc.c (Fgetenv_internal): Mark as internal.
9524 * composite.c (Fremove_list_of_text_properties): Remove decl.

9553 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
9554
9555 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
9556 change. (Bug#8496)
9557
9558 2011-04-13 Eli Zaretskii <eliz@gnu.org>
9559
9560 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
9561 when at ZV. (Bug#8487)
9562
9563 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
9564
9565 * charset.c (Fclear_charset_maps): Use xfree instead of free.
9566 (Bug#8437)
9567 * keyboard.c (parse_tool_bar_item): Likewise.
9568 * sound.c (sound_cleanup, alsa_close): Likewise.

9572
9573 * alloc.c (overrun_check_malloc, overrun_check_realloc)
9574 (overrun_check_free): Protoize.
9575
9576 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
9577
9578 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
9579 since callers should never pass a negative size.
9580 Change the signature to match that of plain 'read' and 'write'; see
9581 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
9582 * lisp.h: Update prototypes of emacs_write and emacs_read.
9583
9584 2011-04-11 Eli Zaretskii <eliz@gnu.org>
9585
9586 * xdisp.c (redisplay_window): Don't try to determine the character
9587 position of the scroll margin if the window start point w->startp
9588 is outside the buffer's accessible region. (Bug#8468)
9589
9590 2011-04-10 Eli Zaretskii <eliz@gnu.org>
9591
9592 Fix write-region and its subroutines for buffers > 2GB.
9593 * fileio.c (a_write, e_write): Modify declaration of arguments and
9594 local variables to support buffers larger than 2GB.
9595 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
9596
9597 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
9598 argument, local variables, and return value.
9599
9600 * lisp.h: Update prototypes of emacs_write and emacs_read.
9601
9602 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
9603
9604 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
9605
9606 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
9607
9608 Fix more problems found by GCC 4.6.0's static checks.
9609
9610 * xdisp.c (vmessage): Use a better test for character truncation.
9611
9612 * charset.c (load_charset_map): <, not <=, for optimization,
9613 and to avoid potential problems with integer overflow.
9614 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
9615 * casetab.c (set_identity, shuffle): Likewise.
9616 * editfns.c (Fformat): Likewise.
9617 * syntax.c (skip_chars): Likewise.
9618
9619 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
9620 This also lets GCC 4.6.0 generate slightly better loop code.
9621
9622 * callint.c (Fcall_interactively): <, not <=, for optimization.
9623 (Fcall_interactively): Count the number of arguments produced,
9624 not the number of arguments given. This is simpler and lets GCC
9625 4.6.0 generate slightly better code.
9626
9627 * ftfont.c: Distingish more carefully between FcChar8 and char.
9628 The previous code passed unsigned char * to a functions like
9629 strlen and xstrcasecmp that expect char *, which does not
9630 conform to the C standard.
9631 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
9632 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
9633 char * when the C standard requires it.
9634
9635 * keyboard.c (read_char): Remove unused var.
9636
9637 * eval.c: Port to Windows vsnprintf (Bug#8435).
9638 Include <limits.h>.
9639 (SIZE_MAX): Define if the headers do not.
9640 (verror): Do not give up if vsnprintf returns a negative count.
9641 Instead, grow the buffer. This ports to Windows vsnprintf, which
9642 does not conform to C99. Problem reported by Eli Zaretskii.
9643 Also, simplify the allocation scheme, by avoiding the need for
9644 calling realloc, and removing the ALLOCATED variable.
9645
9646 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
9647
9648 Remove invocations of doprnt, as Emacs now uses vsnprintf.
9649 But keep the doprint source code for now, as we might revamp it
9650 and use it again (Bug#8435).
9651 * lisp.h (doprnt): Remove.
9652 * Makefile.in (base_obj): Remove doprnt.o.
9653 * deps.mk (doprnt.o): Remove.
9654
9655 error: Print 32- and 64-bit integers portably (Bug#8435).
9656 Without this change, on typical 64-bit hosts error ("...%d...", N)
9657 was used to print both 32- and 64-bit integers N, which relied on
9658 undefined behavior.
9659 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
9660 * lisp.h (error, verror): Mark as printf-like functions.
9661 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
9662 Report overflow in size calculations when allocating printf buffer.
9663 Do not truncate output string at its first null byte.
9664 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
9665 Truncate the output at a character boundary, since vsnprintf does not
9666 do that.
9667 * charset.c (check_iso_charset_parameter): Convert internal
9668 character to string before calling 'error', since %c now has the
9669 printf meaning.
9670 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
9671 overflow when computing char to be passed to 'error'. Do not
9672 pass Lisp_Object to 'error'; pass the integer instead.
9673 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
9674 formatted with plain %d.
9675
9676 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
9677
9678 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
9679
9680 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
9681
9682 * xterm.c (x_catch_errors): Remove duplicate declaration.
9683
9684 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
9685
9686 * xdisp.c, lisp.h (message_nolog): Remove; unused.
9687
9688 2011-04-10 Jim Meyering <meyering@redhat.com>
9689
9690 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
9691 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
9692 return ssize_t not "int", and use size_t as the buffer length.
9693 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
9694 * gnutls.h: Update declarations.
9695 * process.c (read_process_output): Use ssize_t, to match.
9696 (send_process): Likewise.
9697
9698 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
9699
9700 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
9701
9702 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
9703
9704 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
9705 Use unsigned char, to match FcChar8 type definition.
9706
9707 * xterm.c (handle_one_xevent):
9708 * xmenu.c (create_and_show_popup_menu):
9709 * xselect.c (x_decline_selection_request)
9710 (x_reply_selection_request): Avoid type-punned deref of X events.
9711
9712 2011-04-09 Eli Zaretskii <eliz@gnu.org>
9713
9714 Fix some uses of `int' instead of EMACS_INT.
9715 * search.c (string_match_1, fast_string_match)
9716 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
9717 (scan_buffer, find_next_newline_no_quit)
9718 (find_before_next_newline, search_command, Freplace_match)
9719 (Fmatch_data): Make some `int' variables be EMACS_INT.
9720
9721 * xdisp.c (display_count_lines): 3rd argument and return value now
9722 EMACS_INT. All callers changed.
9723 (pint2hrstr): Last argument is now EMACS_INT.
9724
9725 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
9726 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
9727 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
9728 (decode_coding_utf_16, decode_coding_emacs_mule)
9729 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
9730 (decode_coding_ccl, decode_coding_charset)

9733 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
9734 <char_offset, last_offset>: Declare EMACS_INT.

9736 (encode_coding_emacs_mule, encode_invocation_designation)
9737 (encode_designation_at_bol, encode_coding_iso_2022)
9738 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
9739 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
9740 Declare EMACS_INT.
9741 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
9742 (encode_invocation_designation): Last argument P_NCHARS is now
9743 EMACS_INT.
9744 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
9745 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
9746
9747 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
9748 All users changed.
9749
9750 * ccl.c (Fccl_execute_on_string): Declare some variables
9751 EMACS_INT.
9752
9753 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
9754

9764
9765 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
9766
9767 * keyboard.c (read_char): Call Lisp function help-form-show,
9768 instead of using internal_with_output_to_temp_buffer.
9769 (Qhelp_form_show): New var.
9770 (syms_of_keyboard): Use DEFSYM macro.
9771
9772 * print.c (internal_with_output_to_temp_buffer): Function deleted.
9773
9774 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
9775

9786
9787 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
9788
9789 Fix more problems found by GCC 4.6.0's static checks.

9811 This avoids several warnings with gcc -Wstrict-overflow.
9812 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
9813 directly, rather than having caller test rule sign. This avoids
9814 some unnecessary tests.
9815 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
9816 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
9817 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
9818
9819 * xfont.c (xfont_text_extents): Remove var that was set but not used.
9820 (xfont_open): Avoid unnecessary tests.
9821
9822 * composite.c (composition_gstring_put_cache): Use unsigned integer.

9828 breaking out part of COMPOSITION_DECODE_RULE.
9829 (COMPOSITION_DECODE_RULE): Use it.
9830 * composite.c (get_composition_id): Remove unused local vars,
9831 by using the new macro.
9832
9833 * textprop.c (set_text_properties_1): Change while to do-while,
9834 since the condition is always true at first.
9835
9836 * intervals.c (graft_intervals_into_buffer): Mark var as used.
9837 (interval_deletion_adjustment): Return unsigned value.
9838 All uses changed.
9839
9840 * process.c (list_processes_1, create_pty, read_process_output):
9841 (exec_sentinel): Remove vars that were set but not used.

9851
9852 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
9853 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
9854 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
9855
9856 * print.c (print_error_message): Avoid int overflow.
9857
9858 * font.c (font_list_entities): Redo for clarity,
9859 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
9860
9861 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
9862 (font_score): Avoid potential overflow in diff calculation.
9863
9864 * fns.c (substring_both): Remove var that is set but not used.
9865 (sxhash): Redo loop for clarity and to avoid wraparound warning.
9866
9867 * eval.c (funcall_lambda): Rename local to avoid shadowing.
9868
9869 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
9870 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
9871 can always succeed if overflow has undefined behavior.
9872
9873 * search.c (boyer_moore, wordify): Remove vars set but not used.
9874 (wordify): Omit three unnecessary tests.
9875
9876 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
9877 All callers changed. This avoids the need for an unused var.
9878
9879 * casefiddle.c (casify_region): Remove var that is set but not used.
9880
9881 * dired.c (file_name_completion): Remove var that is set but not used.

9889 Check for integer overflow on size calculations.
9890
9891 * buffer.c (Fprevious_overlay_change): Remove var that is set
9892 but not used.
9893

9900
9901 * image.c (lookup_image): Remove var that is set but not used.
9902 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
9903
9904 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
9905 that are set but not used.
9906
9907 * xfns.c (make_invisible_cursor): Don't return garbage
9908 if XCreateBitmapFromData fails (Bug#8410).
9909
9910 * xselect.c (x_get_local_selection, x_handle_property_notify):
9911 Remove vars that are set but not used.
9912
9913 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
9914 (make_invisible_cursor): Initialize a possibly-uninitialized variable.

9919 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
9920 Check for overflow.
9921
9922 * xfaces.c (realize_named_face): Remove vars that are set but not used.
9923 (map_tty_color) [!defined MSDOS]: Likewise.
9924
9925 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
9926
9927 * coding.c: Remove vars that are set but not used.
9928 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
9929 All callers changed.
9930 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
9931 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
9932 (decode_coding_charset): Remove vars that are set but not used.
9933
9934 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
9935 that is set but not used.
9936
9937 * print.c (print_object): Remove var that is set but not used.
9938
9939 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
9940 The gnulib version avoids calling malloc in the usual case,
9941 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
9942 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
9943 * filelock.c (current_lock_owner): Likewise.
9944 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
9945 * sysdep.c: Include allocator.h, careadlinkat.h.
9946 (emacs_no_realloc_allocator): New static constant.
9947 (emacs_readlink): New function.
9948 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
9949 ../lib/careadlinkat.h.
9950
9951 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
9952
9953 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
9954 first non-nil return value).
9955
9956 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
9957
9958 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
9959 if not defined (Bug#8403).
9960
9961 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
9962
9963 * xdisp.c (display_count_lines): Remove parameter `start',
9964 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
9965 (get_char_face_and_encoding): Remove parameter `multibyte_p',
9966 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

9978
9979 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
9980
9981 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
9982
9983 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
9984
9985 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
9986 later (Bug#8403).
9987
9988 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
9989
9990 Add lexical binding.
9991
9992 * window.c (Ftemp_output_buffer_show): New fun.

9994 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
9995
9996 * lread.c (lisp_file_lexically_bound_p): New function.
9997 (Fload): Bind Qlexical_binding.
9998 (readevalloop): Remove `evalfun' arg.
9999 Bind Qinternal_interpreter_environment.
10000 (Feval_buffer): Bind Qlexical_binding.
10001 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
10002 Mark as dynamic.
10003 (syms_of_lread): Declare `lexical-binding'.
10004
10005 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
10006
10007 * keyboard.c (eval_dyn): New fun.
10008 (menu_item_eval_property): Use it.
10009
10010 * image.c (parse_image_spec): Use Ffunctionp.
10011
10012 * fns.c (concat, mapcar1): Accept byte-code-functions.
10013
10014 * eval.c (Fsetq): Handle lexical vars.
10015 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
10016 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
10017 (FletX, Flet): Obey lexical binding.
10018 (Fcommandp): Handle closures.
10019 (Feval): New `lexical' arg.
10020 (eval_sub): New function extracted from Feval. Use it almost
10021 everywhere where Feval was used. Look up vars in lexical env.
10022 Handle closures.
10023 (Ffunctionp): Move from subr.el.
10024 (Ffuncall): Handle closures.
10025 (apply_lambda): Remove `eval_flags'.
10026 (funcall_lambda): Handle closures and new byte-code-functions.
10027 (Fspecial_variable_p): New function.
10028 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
10029 but without exporting it to Lisp.
10030
10031 * doc.c (Fdocumentation, store_function_docstring):
10032 * data.c (Finteractive_form): Handle closures.
10033
10034 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
10035 interactive spec.
10036
10037 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
10038 New byte-codes.
10039 (exec_byte_code): New function extracted from Fbyte_code to handle new
10040 calling convention for byte-code-functions. Add new byte-codes.
10041
10042 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
10043
10044 * alloc.c (Fmake_symbol): Init new `declared_special' field.
10045
10046 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
10047
10048 * xdisp.c (redisplay_internal): Fix prototype.
10049
10050 2011-03-31 Eli Zaretskii <eliz@gnu.org>
10051
10052 * xdisp.c (SCROLL_LIMIT): New macro.
10053 (try_scrolling): Use it when setting scroll_limit.
10054 Limit scrolling to 100 screen lines.
10055 (redisplay_window): Even when falling back on "recentering",
10056 position point in the window according to scroll-conservatively,
10057 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
10058
10059 (try_scrolling): When point is above the window, allow searching
10060 as far as scroll_max, or one screenful, to compute vertical
10061 distance from PT to the scroll margin position. This prevents
10062 try_scrolling from unnecessarily failing when
10063 scroll-conservatively is set to a value slightly larger than the
10064 window height. Clean up the case of PT below the margin at bottom
10065 of window: scroll_max can no longer be INT_MAX. When aggressive
10066 scrolling is in use, don't let point enter the opposite scroll
10067 margin as result of the scroll.
10068 (syms_of_xdisp) <scroll-conservatively>: Document the
10069 threshold of 100 lines for never-recentering scrolling.
10070
10071 2011-03-31 Juanma Barranquero <lekktu@gmail.com>

10076 (message_log_check_duplicate): Remove parameters `prev_bol' and
10077 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
10078 (redisplay_internal): Remove parameter `preserve_echo_area',
10079 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
10080
10081 * indent.c (Fvertical_motion):
10082 * window.c (window_scroll_pixel_based, Frecenter):
10083 Don't pass `need_y_p' to `move_it_by_lines'.
10084
10085 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
10086
10087 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
10088 steal a few bits to be more compact.
10089 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
10090 Remove unneeded casts.
10091
10092 * bytecode.c (Fbyte_code): CAR and CDR can GC.
10093
10094 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
10095
10096 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
10097 binding" message (bug#7967).
10098
10099 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
10100
10101 Fix more problems found by GCC 4.6.0's static checks.
10102
10103 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
10104 Remove unused local var.
10105
10106 * editfns.c (Fmessage_box): Remove unused local var.
10107
10108 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
10109 (note_mode_line_or_margin_highlight, note_mouse_highlight):
10110 Omit unused local vars.
10111 * window.c (shrink_windows): Omit unused local var.
10112 * menu.c (digest_single_submenu): Omit unused local var.
10113 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
10114 Omit unused local var.
10115
10116 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
10117 Don't assume string length fits in int.
10118 (keyremap_step, read_key_sequence): Use size_t for sizes.
10119 (read_key_sequence): Don't check last_real_key_start redundantly.
10120
10121 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
10122 instead of alloca (Bug#8344).
10123
10124 * eval.c (Fbacktrace): Don't assume nargs fits in int.
10125 (Fbacktrace_frame): Don't assume nframes fits in int.
10126
10127 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
10128
10129 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
10130 concerns.
10131
10132 * term.c (produce_glyphless_glyph): Remove unnecessary test.
10133
10134 * cm.c (calccost): Turn while-do into do-while, for clarity.
10135
10136 * keyboard.c (syms_of_keyboard): Use the same style as later
10137 in this function when indexing through an array. This also
10138 works around GCC bug 48267.
10139
10140 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
10141
10142 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
10143
10144 * chartab.c (sub_char_table_ref_and_range): Redo for slight
10145 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
10146
10147 * keyboard.c, keyboard.h (num_input_events): Now size_t.
10148 This avoids undefined behavior on integer overflow, and is a bit
10149 more convenient anyway since it is compared to a size_t variable.
10150
10151 Variadic C functions now count arguments with size_t, not int.
10152 This avoids an unnecessary limitation on 64-bit machines, which
10153 caused (substring ...) to crash on large vectors (Bug#8344).
10154 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
10155 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
10156 All variadic functions and their callers changed accordingly.
10157 (struct gcpro.nvars): Now size_t, not int. All uses changed.
10158 * data.c (arith_driver, float_arith_driver): Likewise.
10159 * editfns.c (general_insert_function): Likewise.
10160 * eval.c (struct backtrace.nargs, interactive_p)
10161 (internal_condition_case_n, run_hook_with_args, apply_lambda)
10162 (funcall_lambda, mark_backtrace): Likewise.
10163 * fns.c (concat): Likewise.
10164 * frame.c (x_set_frame_parameters): Likewise.
10165 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
10166 0 if not found, not -1. All callers changed.
10167
10168 * alloc.c (garbage_collect): Don't assume stack size fits in int.
10169 (stack_copy_size): Now size_t, not int.
10170 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
10171

10176 All callers changed.
10177
10178 * lisp.h (multibyte_char_to_unibyte):
10179 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
10180 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
10181 * character.h (CHAR_TO_BYTE8):
10182 * cmds.c (internal_self_insert):
10183 * editfns.c (general_insert_function):
10184 * keymap.c (push_key_description):
10185 * search.c (Freplace_match):
10186 * xdisp.c (message_dolog, set_message_1): All callers changed.
10187
10188 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
10189
10190 * keyboard.c (safe_run_hook_funcall): New function.
10191 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
10192 don't set the hook to nil, but remove the offending function instead.
10193 (Qcommand_hook_internal): Remove, unused.
10194 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
10195 Vcommand_hook_internal.
10196
10197 * eval.c (enum run_hooks_condition): Remove.
10198 (funcall_nil, funcall_not): New functions.
10199 (run_hook_with_args): Call each function through a `funcall' argument.
10200 Remove `cond' argument, now redundant.
10201 (Frun_hooks, Frun_hook_with_args, Frun_hook_with_args_until_success)
10202 (Frun_hook_with_args_until_failure): Adjust accordingly.
10203 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
10204
10205 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
10206
10207 * dispextern.h (string_buffer_position): Remove declaration.

10380
10381 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
10382
10383 Fix more problems found by GCC 4.5.2's static checks.
10384
10385 * coding.c (encode_coding_raw_text): Avoid unnecessary test
10386 the first time through the loop, since we know p0 < p1 then.
10387 This also avoids a gcc -Wstrict-overflow warning.
10388
10389 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
10390 leading to a memory leak, possible in functions like
10391 load_charset_map_from_file that can allocate an unbounded number
10392 of objects (Bug#8318).
10393
10394 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
10395 that could (at least in theory) be that large.
10396
10397 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
10398 This is less likely to overflow, and avoids undefined behavior if
10399 overflow does occur. All callers changed. Use strtoul to scan
10400 for the unsigned long integer.
10401 (pint2hrstr): Simplify and tune code slightly.
10402 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
10403

10410 This also avoids a warning with gcc -Wstrict-overflow.
10411
10412 * fileio.c (Fcopy_file): Report error if fchown or fchmod
10413 fail (Bug#8306).
10414
10415 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
10416
10417 * process.c (Fmake_network_process): Use socklen_t, not int,
10418 where POSIX says socklen_t is required in portable programs.
10419 This fixes a porting bug on hosts like 64-bit HP-UX, where
10420 socklen_t is wider than int (Bug#8277).
10421 (Fmake_network_process, server_accept_connection):
10422 (wait_reading_process_output, read_process_output):
10423 Likewise.
10424
10425 * process.c: Rename or move locals to avoid shadowing.

10430 (Fnetwork_interface_info): Fix pointer signedness.
10431 (process_send_signal): Add cast to avoid pointer signedness problem.
10432 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
10433 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
10434
10435 Make tparam.h and terminfo.c consistent.
10436 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
10437 Include tparam.h instead, since it declares them.
10438 * cm.h (PC): Remove extern decl; tparam.h now does this.
10439 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
10440 * terminfo.c: Include tparam.h, to check interfaces.
10441 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
10442 (tparam): Adjust signature to match interface in tparam.h;
10443 this removes some undefined behavior. Check that outstring and len
10444 are zero, which they always are with Emacs.
10445 * tparam.h (PC, BC, UP): New extern decls.
10446
10447 * xftfont.c (xftfont_shape): Now static, and defined only if needed.

10456 Rename locals to avoid shadowing.
10457
10458 * xfont.c (xfont_list_family): Mark var as initialized.
10459
10460 * xml.c (make_dom): Now static.
10461
10462 * composite.c (composition_compute_stop_pos): Rename local to
10463 avoid shadowing.
10464 (composition_reseat_it): Remove unused locals.
10465 (find_automatic_composition, composition_adjust_point): Likewise.
10466 (composition_update_it): Mark var as initialized.
10467 (find_automatic_composition): Mark vars as initialized,
10468 with a FIXME (Bug#8290).
10469
10470 character.h: Rename locals to avoid shadowing.
10471 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):

10473 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
10474 (BUF_DEC_POS): Be more systematic about renaming local temporaries
10475 to avoid shadowing.
10476

10478
10479 * intervals.c (interval_start_pos): Now static.
10480
10481 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
10482

10484 Rename locals to avoid shadowing.
10485
10486 * sound.c (wav_play, au_play, Fplay_sound_internal):
10487 Fix pointer signedness.
10488 (alsa_choose_format): Remove unused local var.
10489 (wav_play): Initialize a variable to 0, to prevent undefined
10490 behavior (Bug#8278).
10491
10492 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
10493
10494 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
10495
10496 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
10497 clobbering (Bug#8298).
10498 * sysdep.c (sys_subshell): Likewise.
10499 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
10500
10501 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
10502 This should get cleaned up, so that child_setup has the
10503 same signature on all platforms.
10504
10505 * callproc.c (call_process_cleanup): Now static.
10506 (relocate_fd): Rename locals to avoid shadowing.
10507
10508 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
10509
10510 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
10511 not to be necessary, and produces flickering.
10512
10513 2011-03-20 Glenn Morris <rgm@gnu.org>
10514
10515 * config.in: Remove file.

10520 are now in src/globals.h.
10521 (syms_of_minibuf): Remove spurious & from previous change.
10522
10523 2011-03-20 Leo Liu <sdl.web@gmail.com>

10547 (sigchld_handler): Now static.
10548
10549 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
10550 That way, the code declares only the vars that it needs.
10551 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
10552 * s/cygwin.h (PTY_ITERATION): Likewise.
10553 * s/darwin.h (PTY_ITERATION): Likewise.

10567 n rather than nn, a way that does not involve shadowing.
10568 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
10569
10570 * deps.mk (unexalpha.o): Remove; unused.

10618 * alloc.c (mark_backtrace): Move decl from here ...
10619 * lisp.h: ... to here, so that it can be checked.
10620
10621 * eval.c (call_debugger, do_debug_on_call, grow_specpdl): Now static.
10622 (Fdefvar): Rewrite so as not to use empty "else".

10624 to avoid gcc -Wbad-function-cast warning.
10625 (Fdefvar): Rename locals to avoid shadowing.
10626
10627 * callint.c (quotify_arg, quotify_args): Now static.

10629 Use const pointer when appropriate.
10630
10631 * lisp.h (get_system_name, get_operating_system_release):
10632 Move decls here, to check interfaces.
10633 * process.c (get_operating_system_release): Move decl to lisp.h.
10634 * xrdb.c (get_system_name): Likewise.
10635 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
10636 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
10637 some of which prompt warnings from gcc -Wbad-function-cast.
10638 (Fformat_time_string, Fencode_time, Finsert_char):
10639 (Ftranslate_region_internal, Fformat):
10640 Rename or remove local vars to avoid shadowing.
10641 (Ftranslate_region_internal): Mark var as initialized.
10642
10643 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
10644 avoid shadowing.
10645
10646 * lisp.h (eassert): Check that the argument compiles, even if
10647 ENABLE_CHECKING is not defined.
10648
10649 * data.c (Findirect_variable): Name an expression, to avoid
10650 gcc -Wbad-function-cast warning.
10651 (default_value, arithcompare, arith_driver, arith_error): Now static.
10652 (store_symval_forwarding): Rename local to avoid shadowing.

10654 Mark variables as initialized.
10655 (do_blv_forwarding, do_symval_forwarding): Remove; unused.
10656
10657 * alloc.c (check_cons_list): Do not define unless GC_CHECK_CONS_LIST.

10660 (mark_stack): Move local variables into the #ifdef region where
10661 they're used.
10662 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
10663 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
10664 needed otherwise.
10665 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
10666 (GC_STRING_CHARS): Remove; not used.
10667 (Fmemory_limit): Cast sbrk's returned value to char *.
10668
10669 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
10670 avoids undefined behavior in theory.
10671
10672 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
10673
10674 Use functions, not macros, for up- and down-casing (Bug#8254).
10675 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
10676 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
10677 to use the following functions instead of these macros.
10678 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
10679 EMACS_INT, since callers assume the returned value fits in int.
10680 (upcase1): Likewise, for UPCASE_TABLE.
10681 (uppercasep, lowercasep, upcase): New static inline functions.
10682 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

10686 Rename locals to avoid shadowing.
10687 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
10688 (regex_compile, re_search_2, re_match_2_internal):
10689 Remove unused local vars.
10690 (FREE_VAR): Rewrite so as not to use empty "else",
10691 which gcc can warn about.
10692 (regex_compile, re_match_2_internal): Mark locals as initialized.
10693 (RETALLOC_IF): Define only if needed.
10694 (WORDCHAR_P): Likewise. This one is never needed, but is used
10695 only in a comment talking about a compiler bug, so put inside
10696 the #if 0 of that comment.
10697 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
10698 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
10699 Remove; unused.
10700
10701 * search.c (boyer_moore): Rename locals to avoid shadowing.
10702 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
10703 (PREV_CHAR_BOUNDARY): Likewise.
10704
10705 * search.c (simple_search): Remove unused var.
10706
10707 * dired.c (compile_pattern): Move decl from here ...
10708 * lisp.h: ... to here, so that it can be checked.
10709 (struct re_registers): New forward decl.
10710
10711 * character.h (INC_POS, DEC_POS): Rename locals to avoid shadowing.
10712
10713 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
10714 All uses changed.
10715 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
10716 Rename locals to avoid shadowing.
10717 (Fvertical_motion): Mark locals as initialized.
10718
10719 * casefiddle.c (casify_object, casify_region): Now static.
10720 (casify_region): Mark local as initialized.
10721
10722 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
10723
10724 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
10725 New macros, so that the caller can use some names other than
10726 gcpro1, gcpro2, etc.
10727 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
10728 of the new macros.
10729 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
10730 argument, for consistency with GCPRO2_VAR, etc: it is now the
10731 prefix of the variable, not the variable itself. All uses
10732 changed.
10733 * dired.c (directory_files_internal, file_name_completion):
10734 Rename locals to avoid shadowing.
10735
10736 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
10737 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
10738 dired.c's scmp function, had undefined behavior.
10739 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
10740 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
10741 * buffer.h: ... to here, because these macros use current_buffer,
10742 and the new implementation with inline functions needs to have
10743 current_buffer in scope now, rather than later when the macros
10744 are used.
10745 (downcase, upcase1): New static inline functions.
10746 (DOWNCASE, UPCASE1): Reimplement using these functions.
10747 This avoids undefined behavior in expressions like
10748 DOWNCASE (x) == DOWNCASE (y), which previously suffered
10749 from race conditions in accessing the global variables
10750 case_temp1 and case_temp2.
10751 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
10752 * lisp.h (case_temp1, case_temp2): Remove their decls.
10753 * character.h (ASCII_CHAR_P): Move from here ...
10754 * lisp.h: ... to here, so that the inline functions mentioned
10755 above can use them.
10756
10757 * dired.c (directory_files_internal_unwind): Now static.
10758
10759 * fileio.c (file_name_as_directory, directory_file_name):
10760 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
10761 Now static.
10762 (file_name_as_directory): Use const pointers when appropriate.
10763 (Fexpand_file_name): Likewise. In particular, newdir might
10764 point at constant storage, so make it a const pointer.
10765 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
10766 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
10767 signedness issues.
10768 (Fset_file_times, Finsert_file_contents, auto_save_error):
10769 Rename locals to avoid shadowing.
10770
10771 * minibuf.c (choose_minibuf_frame_1): Now static.
10772 (Ftry_completion, Fall_completions): Rename or remove locals
10773 to avoid shadowing.
10774
10775 * marker.c (bytepos_to_charpos): Remove; unused.
10776
10777 * lisp.h (verify_bytepos, count_markers): New decls,
10778 so that gcc does not warn that these functions aren't declared.
10779
10780 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
10781 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
10782 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
10783 (copy_text): Remove unused local var.
10784
10785 * filelock.c (within_one_second): Now static.
10786 (lock_file_1): Rename local to avoid shadowing.
10787
10788 * buffer.c (fix_overlays_before): Mark locals as initialized.
10789 (fix_start_end_in_overlays): Likewise. This function should be
10790 simplified by using pointers-to-pointers, but that's a different
10791 matter.
10792 (switch_to_buffer_1): Now static.
10793 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
10794 (report_overlay_modification): Rename locals to avoid shadowing.
10795
10796 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
10797 Fix pointer signedness issue.
10798 (sys_subshell): Mark local as volatile if checking for lint,
10799 to suppress a gcc -Wclobbered warning that does not seem to be right.
10800 (MAXPATHLEN): Define only if needed.
10801
10802 * process.c (serial_open, serial_configure): Move decls from here ...
10803 * systty.h: ... to here, so that they can be checked.
10804
10805 * fns.c (get_random, seed_random): Move extern decls from here ...
10806 * lisp.h: ... to here, so that they can be checked.
10807
10808 * sysdep.c (reset_io): Now static.
10809 (wait_for_termination_signal): Remove; unused.
10810
10811 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
10812 (copy_keymap_item, append_key, push_text_char_description):
10813 Now static.
10814 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
10815 (DENSE_TABLE_SIZE): Remove; unused.
10816 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
10817 (describe_map_tree):
10818 Rename locals to avoid shadowing.
10819
10820 * keyboard.c: Declare functions static if they are not used elsewhere.
10821 (echo_char, echo_dash, cmd_error, top_level_2):
10822 (poll_for_input, handle_async_input): Now static.
10823 (read_char, kbd_buffer_get_event, make_lispy_position):

10830
10831 * keyboard.h (make_ctrl_char): New decl.
10832 (mark_kboards): Move decl here ...
10833 * alloc.c (mark_kboards): ... from here.
10834
10835 * lisp.h (force_auto_save_soon): New decl.
10836
10837 * emacs.c (init_cmdargs): Rename local to avoid shadowing.
10838 (DEFINE_DUMMY_FUNCTION): New macro.
10839 (__do_global_ctors, __do_global_ctors_aux, __do_global_dtors, __main):
10840 Use it.
10841 (main): Add casts to avoid warnings
10842 if GCC considers string literals to be constants.
10843
10844 * lisp.h (fatal_error_signal): Add decl, since it's exported.
10845
10846 * dbusbind.c: Pointer signedness fixes.
10847 (xd_signature, xd_append_arg, xd_initialize):
10848 (Fdbus_call_method, Fdbus_call_method_asynchronously):

10967 For example, without this patch (encode-time 0 0 0 1 1
10968 1152921504606846976) returns the obviously-bogus value (-948597
10969 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
10970 reports time overflow. See
10971 <http://lists.gnu.org/archive/html/emacs-devel/2011-03/msg00470.html>.
10972 * deps.mk (editfns.o): Depend on ../lib/intprops.h.

10982 (check_tm_member): New function.
10983 (Fencode_time): Use it, to test for out-of-range times.
10984 (lisp_time_argument): Don't rely on undefined left-shift and
10985 right-shift behavior when checking for time stamp overflow.
10986
10987 * editfns.c (time_overflow): New function, refactoring common code.
10988 (Fformat_time_string, Fdecode_time, Fencode_time):
