470 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
471 Otherwise, valgrind does not work on some platforms.
472 Problem reported by Andreas Schwab in
473 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
474 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
475 is set, removing the need for VIRT_ADDRESS_VARIES.
476 (PURE_P): Use a more-efficient implementation that needs just one
477 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
478 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
479 to 4 (xorl, subq, cmpq, setbe).
480 * alloc.c (pure): Always extern now, since that's the
481 VIRT_ADDR_VARIES behavior.
482 (PURE_POINTER_P): Use a single comparison, not two, for
483 consistency with the new puresize.h.
484 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
485 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:
486 Remove VIRT_ADDR_VARIES no longer needed.

489
490 * xdisp.c (x_write_glyphs, draw_phys_cursor_glyph)
491 (erase_phys_cursor, update_window_cursor, show_mouse_face)
492 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
493 behave as if the cursor position were at the window margin.
494
495 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
496 and the cursor position is out of bounds, behave as if the cursor
497 position were at the window margin. (Bug#10075)
498
499 2011-11-18 Chong Yidong <cyd@gnu.org>
500
501 * window.c (Fwindow_combination_limit): Make first argument

520 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
521
522 * xdisp.c (row_hash): New function, body extracted from
523 compute_line_metrics.
524 (compute_line_metrics): Call row_hash, instead of computing the
525 hash code inline.
526
527 * dispnew.c (verify_row_hash): Call row_hash for computing the
528 hash code of a row, instead of duplicating code from xdisp.c.
529
530 * dispextern.h (row_hash): Add prototype.

567
568 2011-11-14 Eli Zaretskii <eliz@gnu.org>
569
570 * xdisp.c (display_line): Move the call to
571 highlight_trailing_whitespace before the call to
572 compute_line_metrics, since the latter needs to see the final
573 faces of all the glyphs to compute ROW's hash value.
574 Fixes assertion violations in row_equal_p. (Bug#10035)
575
576 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
577
578 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
579 just return (bug#10044).
580
581 2011-11-12 Eli Zaretskii <eliz@gnu.org>
582
583 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
584 with user-defined heap size. Bump the default size of the temacs
585 heap to 27MB, to avoid memory warning when running temacs.
586 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
587
588 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
589 current_matrix and desired_matrix. (Bug#9990)

637 Avoid some portability problems by eschewing 'extern inline' functions.
638 The trivial performance wins aren't worth the portability hassles; see
639 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
640 et seq.
641 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

688
689 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
690 This is also needed for porting to any host where GC_MARK_STACK is
691 not GC_MAKE_GCPROS_NOOPS.

693
694 2011-11-07 Kenichi Handa <handa@m17n.org>

706
707 * xmenu.c (cleanup_widget_value_tree): New function.
708 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of

715 (window_box_width, window_box_left, window_box_left_offset)
716 (window_box_right, window_box_right_offset): Declare extern.
717 Otherwise, these inline functions do not conform to C99 and
718 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
719 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
720 * intervals.c (adjust_intervals_for_insertion)
721 (adjust_intervals_for_deletion): Now extern, because otherwise the
722 extern inline functions 'offset_intervals' couldn't refer to it.
723 (static_offset_intervals): Remove.
724 (offset_intervals): Rewrite using the old contents of
725 static_offset_intervals. The old version didn't conform to C99
726 because an extern inline function contained a reference to an

748 (Fwindow_margins, Fwindow_fringes, Fwindow_scroll_bars)
749 (Fwindow_vscroll): Doc fix.

793 official. Move initialization of image_cache_refcount and
794 dpyinfo_refcount before calling init_frame_faces (Bug#9943).

797
798 Support MSVC build with newer versions of Visual Studio.
799 * makefile.w32-in (TAGS-gmake): Don't use $(patsubst ...), as

885 * xterm.h (x_display_info): Add Xatom_net_wm_state_hidden (Bug#9893).
886
887 * xterm.c: Declare x_handle_net_wm_state to return int.
888 (handle_one_xevent): Check if we are iconified but don't have
889 _NET_WM_STATE_HIDDEN. If do, treat as deiconify (Bug#9893).
890 (get_current_wm_state): Return non-zero if not hidden,
891 check for _NET_WM_STATE_HIDDEN (Bug#9893).
892 (do_ewmh_fullscreen): Ignore return value from get_current_wm_state.
893 (x_handle_net_wm_state): Return what get_current_wm_state returns.
894 (x_term_init): Initialize dpyinfo->Xatom_net_wm_state_hidden.
895
896 2011-10-29 Paul Eggert <eggert@cs.ucla.edu>
897
898 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
899 so that this new function doesn't get optimized away by a
900 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
901
902 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
903
904 * frame.h (MOUSE_HL_INFO): Remove excess parens.
905
906 2011-10-29 Eli Zaretskii <eliz@gnu.org>
907
908 Fix the `xbytecode' command.
909 * .gdbinit (xprintbytestr): New command.
910 (xwhichsymbols): Rename from `which'; all callers changed.
911 (xbytecode): Print the byte-code string as well.
912
913 2011-10-29 Kim Storm <storm@cua.dk>
914
915 * alloc.c (which_symbols): New function.

920 line. (Bug#9903)
921
922 2011-10-29 Glenn Morris <rgm@gnu.org>
923
924 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
925 Not clear what it was for, and it causes various bugs. (Bug#9839)
926
927 2011-10-28 Eli Zaretskii <eliz@gnu.org>
928
929 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
930 possible random value that matches one of those tested as
931 condition to clear the mouse face.
932
933 2011-10-28 Chong Yidong <cyd@gnu.org>
934
935 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.
936
937 2011-10-28 Dan Nicolaescu <dann@ics.uci.edu>

948
949 2011-10-28 Eli Zaretskii <eliz@gnu.org>
950
951 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
952 <oslsachem@gmail.com> for helping to debug this.
953
954 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
955 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
956 (g_b_init_get_glyph_outline_w): New static variables.
957 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
958 (GetGlyphOutlineW_Proc): New typedefs.
959 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
960 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
961 New functions.
962 (w32font_open_internal, compute_metrics):
963 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
964 instead of calling the "wide" APIs directly.
965
966 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
967
968 * w32.h (syms_of_w32font): Add prototype.
969
970 2011-10-27 Juanma Barranquero <lekktu@gmail.com>

973 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
974 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
975 (Fmove_to_window_line): Doc fix.
976
977 2011-10-27 Chong Yidong <cyd@gnu.org>
978
979 * process.c (make_process): Set gnutls_state to NULL.
980
981 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
982 non-NULL, regardless of GNUTLS_INITSTAGE.
983 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
984 an error. Set process slots as soon as we allocate them.
985
986 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
987
988 2011-10-27 Chong Yidong <cyd@gnu.org>
989
990 * gnutls.c (emacs_gnutls_deinit): New function.
991 Deallocate credentials structures as well as calling gnutls_deinit.
992 (Fgnutls_deinit, Fgnutls_boot): Use it.
993
994 * process.c (make_process): Initialize GnuTLS credentials to NULL.
995 (deactivate_process): Call emacs_gnutls_deinit.
996

998
999 * image.c (x_create_x_image_and_pixmap):
1000 * w32.c (sys_rename, w32_delayed_load):
1001 * w32font.c (fill_in_logfont):
1002 * w32reg.c (x_get_string_resource): Silence compiler warnings.

1007 extracted from Fw32_default_color_map.
1008 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
1009
1010 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
1011
1012 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
1013
1014 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
1015
1016 * keyboard.c (test_undefined): New function (bug#9751).

1018
1019 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
1020
1021 * sysdep.c (init_sys_modes): Fix the check for the controlling
1022 terminal (Bug#6649).
1023
1024 2011-10-20 Eli Zaretskii <eliz@gnu.org>
1025
1026 * dispextern.h (struct bidi_it): New member next_en_type.
1027
1028 * bidi.c (bidi_line_init): Initialize the next_en_type member.
1029 (bidi_resolve_explicit_1): When next_en_pos is valid for the
1030 current character, check also for next_en_type being WEAK_EN.
1031 (bidi_resolve_weak): Don't enter the expensive loop if the current
1032 position is before next_en_pos. Record the bidi type of the first
1033 non-ET, non-BN character we find, in addition to its position.
1034 (bidi_level_of_next_char): Invalidate next_en_type when
1035 next_en_pos is over-stepped.
1036
1037 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
1038
1039 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
1040 * editfns.c: Rewrite current-time-zone so that it invokes
1041 the equivalent of (format-time-string "%Z") to get the time zone name.
1042 This fixes a bug when the time zone name contains characters that
1043 need converting from the system time locale to Emacs internal format.
1044 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
1045 that patch fixed format-time-string to do the conversion, but
1046 I forgot to fix current-time-zone.
1047 (format_time_string): New function, containing most of
1048 what Fformat_time_string used to contain.
1049 (Fformat_time_string): Rewrite in terms of format_time_string.
1050 This doesn't change this function's behavior.
1051 (current-time-zone): Rewrite to use format_time_string.
1052 This fixes the bug reported by Michael Schierl in
1053 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
1054 Jason Rumney's 2007-06-07 change worked around this bug, but
1055 didn't fix it.
1056 * systime.h (tzname, timezone): Remove no-longer-used declarations.
1057
1058 2011-10-19 Eli Zaretskii <eliz@gnu.org>
1059
1060 * xdisp.c (start_display): If the character at POS is displayed
1061 via a display vector, reset IT->current.dpvec_index to zero.
1062 (try_window_reusing_current_matrix): If a line ends in a display
1063 vector or the next line starts in a display vector, continue
1064 redrawing the window even though the character position of
1065 start_row was reached.
1066 (Bug#9771, part 2)
1067
1068 2011-10-18 Chong Yidong <cyd@gnu.org>
1069
1070 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
1071 with nobreak-char-display too.
1072
1073 2011-10-18 Eli Zaretskii <eliz@gnu.org>
1074
1075 Fix part 3 of bug#9771.
1076 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
1077 (bidi_resolve_neutral): Don't enter the expensive loop looking for
1078 non-neutral characters if the current character is a paragraph
1079 separator (a.k.a. Newline). This avoids running the same
1080 expensive loop twice, once when we consume the preceding newline
1081 and the other time when the line actually needs to be displayed.
1082 Avoid the loop when we see neutrals on the base embedding level
1083 following a character whose directionality is the same as the
1084 paragraph's. This avoids running the expensive loop when a line
1085 ends in a long sequence of neutrals, like control characters.
1086 Add assertion against STRONG_AL type. Slightly rearrange code
1087 that determines the type of a neutral given the first non-neutral
1088 that follows it.
1089 (bidi_level_of_next_char): Set next_en_pos to zero when
1090 invalidating its info.
1091
1092 2011-10-17 Eli Zaretskii <eliz@gnu.org>
1093
1094 * xdisp.c (push_display_prop): Determine whether to record string
1095 or buffer position by IT->string, not by IT->method. Allow
1096 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
1097 (move_it_vertically_backward): Don't look for character position
1098 immediately after the newline when in a continuation line.
1099 (Bug#9771, part 1)
1100
1101 2011-10-15 Martin Rudalics <rudalics@gmx.at>
1102
1103 * window.c (coordinates_in_window): Rewrite and delabelize
1104 vertical border check. (Bug#5357) (Bug#9618)
1105
1106 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
1107
1108 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
1109 errors in XSetWindowBorder (bug#9310).
1110
1111 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
1112
1113 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
1114 avoid crash when xmalloc overrun checking is enabled.
1115
1116 2011-10-13 Eli Zaretskii <eliz@gnu.org>
1117
1118 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
1119 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
1120 cursor motion with <left> and <right> arrow keys.
1121
1122 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
1123 some callers set that themselves.
1124
1125 2011-10-12 Eli Zaretskii <eliz@gnu.org>
1126
1127 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
1128 display string and the previous row comes from the same string and
1129 is empty. (Bug#9739) (Bug#9738)
1130
1131 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
1132
1133 * doc.c (get_doc_string): Encode file name (bug#9735).
1134
1135 2011-10-12 Eli Zaretskii <eliz@gnu.org>
1136
1137 * bidi.c (bidi_level_of_next_char):
1138 * xdisp.c (get_visually_first_element): Remove old incorrect
1139 comments regarding the Unicode Line Separator character.
1140
1141 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
1142
1143 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
1144
1145 * alloc.c (Fgc_status): Do not access beyond zombies array
1146 boundary if nzombies > MAX_ZOMBIES.
1147 * alloc.c (dump_zombies): Add missing format specifier.
1148
1149 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
1150
1151 * xdisp.c (set_cursor_from_row): Simplify conditionals,
1152 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
1153
1154 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
1155 Some packages use them to denote characters with modifiers.
1156
1157 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
1158
1159 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
1160 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
1161 matching a pp-number. Rename parameter var to var1.
1162
1163 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
1164
1165 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
1166
1167 2011-10-08 Glenn Morris <rgm@gnu.org>
1168
1169 * callint.c (Fcall_interactively): Give a more explicit error for the
1170 'c' case with a non-character input. (Bug#8479)
1171
1172 2011-10-08 Eli Zaretskii <eliz@gnu.org>
1173
1174 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
1175 lines.
1176 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
1177 lines that are hscrolled on the left.
1178
1179 * dispnew.c (buffer_posn_from_coords): Account for a possible
1180 presence of header-line. (Bug#4426)
1181
1182 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
1183
1184 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
1185 Don't advertise functionality which we discourage or doesn't work.
1186
1187 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
1188
1189 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
1190 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
1191 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
1192 this makes Emacs dump core during garbage collection on rare
1193 occasions. sizeof is obviously inferior to offsetof here, so
1194 stick with offsetof.
1195 (GC_POINTER_ALIGNMENT): New macro.
1196 (mark_memory): Omit 3rd (offset) arg; caller changed.
1197 Don't assume EMACS_INT alignment is the same as pointer alignment.
1198
1199 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
1200
1201 * keyboard.c (read_key_sequence_remapped): New var.
1202 (read_key_sequence): Compute remapping in the right buffer.
1203 (command_loop_1): Use read_key_sequence's remapping directly.
1204
1205 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
1206
1207 * dired.c (file_name_completion): Don't expand file name.
1208 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
1209 before checking file name handler.
1210
1211 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
1212 they've been requested explicitly (bug#9591).
1213
1214 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
1215
1216 * keymap.c (Fsingle_key_description): Use make_specified_string
1217 instead of build_string to build string from push_key_description.
1218 (Bug#5193)
1219
1220 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
1221
1222 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
1223 This fixes a Y2038 bug on 64-bit hosts.
1224 * buffer.c (reset_buffer):
1225 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
1226 (Fclear_buffer_auto_save_failure):
1227 Use 0, not -1, to represent an unset failure time, since time_t
1228 might not be signed.
1229
1230 Remove dependency on glibc malloc internals.
1231 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
1232 Move back here from lisp.h, but with their new implementations.
1233 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
1234 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
1235 * charset.c (charset_table_init): New static var.
1236 (syms_of_charset): Use it instead of xmalloc. This removes a
1237 dependency on glibc malloc internals. See Eli Zaretskii's comment in
1238 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
1239 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
1240 Move back to alloc.c.
1241 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
1242 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
1243
1244 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
1245
1246 * nsterm.m (windowDidResize): Call x_set_window_size only when
1247 ns_in_resize is true. Otherwise set pixelwidth/height and
1248 call change_frame_size (Bug#9628).
1249
1250 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
1251
1252 Port --enable-checking=all to Fedora 14 x86-64.
1253 * charset.c (syms_of_charset): Also account for glibc malloc's
1254 internal overhead when calculating the initial malloc maximum.
1255
1256 Port --enable-checking=all to Fedora 14 x86.
1257 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
1258 Move to lisp.h.
1259 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
1260 (overrun_check_realloc, overrun_check_free):
1261 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
1262 That way, xmalloc returns a properly-aligned pointer even if
1263 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
1264 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
1265 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
1266 into account when calculating the initial malloc maximum.
1267 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
1268 Move here from alloc.c, so that charset.c can use it too.
1269 Properly align; the old code wasn't right for common 32-bit hosts
1270 when configured with --enable-checking=all.
1271 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
1272 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
1273
1274 2011-09-29 Eli Zaretskii <eliz@gnu.org>
1275
1276 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
1277 use EDOM.
1278
1279 2011-09-28 Eli Zaretskii <eliz@gnu.org>
1280
1281 * xdisp.c (compute_display_string_end): If there's no display
1282 string at CHARPOS, return -1.
1283
1284 * bidi.c (bidi_fetch_char): When compute_display_string_end
1285 returns a negative value, treat the character as a normal
1286 character not covered by a display string. (Bug#9624)
1287
1288 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
1289
1290 * lread.c (Fread_from_string): Fix typo in docstring.
1291
1292 2011-09-27 Eli Zaretskii <eliz@gnu.org>
1293
1294 * xdisp.c (handle_invisible_prop): If invisible text ends on a
1295 newline, reseat the iterator instead of bidi-iterating there one
1296 character at a time. (Bug#9610)
1297 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
1298 TO_CHARPOS if the bidi iterator is at base embedding level.

1332 Default value is now t. Doc fix.
1333
1334 * indent.c (Fvertical_motion): Compute and apply the overshoot
1335 logic when moving up, not only when moving down. Fix the
1336 confusing name and values of the it_overshoot_expected variable;
1337 logic changes accordingly. (Bug#9254) (Bug#9549)
1338
1339 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
1340 CHARPOS is covered by a display string which includes newlines.

1351 2011-09-24 Jim Meyering <meyering@redhat.com>
1352
1353 do not ignore write error for any output size
1354 The previous change was incomplete.
1355 While it makes emacs --batch detect the vast majority of stdout
1356 write failures, errors were still ignored whenever the output size is
1357 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
1358 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
1359 && echo FAIL: ignored write error
1360 FAIL: ignored write error
1361 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
1362 && echo FAIL: ignored write error
1363 FAIL: ignored write error
1364 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
1365
1366 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
1367
1368 * emacs.c (Fkill_emacs): In noninteractive mode exit

1370
1371 2011-09-21 Eli Zaretskii <eliz@gnu.org>
1372
1373 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
1374 the xassert test.
1375
1376 * dispextern.h (struct it): Update the comment documenting what
1377 can it->OBJECT be.
1378
1379 2011-09-20 Eli Zaretskii <eliz@gnu.org>
1380
1381 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
1382 a display string, extend search for cursor position to end of row.
1383 (find_row_edges): If the row ends in a newline from a display
1384 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
1385 Handle the case of a display string with multiple newlines.
1386 (Fcurrent_bidi_paragraph_direction): Fix search for previous
1387 non-empty line. Fixes confusing cursor motion with arrow keys at
1388 the beginning of a line that starts with whitespace.

1399
1400 2011-09-18 Eli Zaretskii <eliz@gnu.org>
1401
1402 * xdisp.c (display_line): Record maximum and minimum buffer
1403 positions even if no glyphs were produced (e.g., by a zero-width
1404 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
1405 buffer positions that will be removed from the glyph row because
1406 they don't fit.
1407 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
1408 column is beyond frame width: don't subtract 1 "pixel" when
1409 computing width of the stretch.
1410 (reseat_at_next_visible_line_start): Undo the change made on
1411 2011-09-17 that saved paragraph information and restored it after
1412 the call to `reseat'. (Bug#9545)

1432 initialized, to pacify gcc -Wuninitialized.
1433
1434 * fileio.c: Report proper errno when syscall falls.
1435 (Finsert_file_contents): Save and restore errno,
1436 so that report_file_error outputs the correct diagnostic.

1453 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
1454 (bidi_find_paragraph_start): Search back for paragraph beginning
1455 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
1456 (bidi_move_to_visually_next): Only trigger paragraph-related
1457 computations when the last character is a newline or at EOB, not
1458 just any NEUTRAL_B. (Bug#9470)
1459
1460 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
1461 truncated lines if point is covered by a display string. (Bug#9524)
1462
1463 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
1464
1465 * xselect.c: Relax test for outgoing X longs (Bug#9498).
1466 (cons_to_x_long): New function.
1467 (lisp_data_to_selection_data): Use it. Correct the test for
1468 short-versus-long data; it was negated. Break out of vector
1469 loop, for efficiency, when a long datum is discovered.
1470
1471 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
1472

1474
1475 2011-09-16 Eli Zaretskii <eliz@gnu.org>
1476
1477 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
1478 GCC PR/17406) by declaring this function with external scope.
1479
1480 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
1481
1482 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).

1484
1485 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
1486

1520 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
1521
1522 * xselect.c: Use signed conversions more consistently (Bug#9498).
1523 (selection_data_to_lisp_data): Assume incoming selection data are
1524 signed integers, not unsigned. This is to be consistent with
1525 outgoing selection data, which was modified to use signed integers
1526 in as part of the fix to Bug#9196 in response to Jan D.'s comment
1527 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
1528 expects long, not unsigned long.

1552
1553 2011-09-11 Eli Zaretskii <eliz@gnu.org>
1554
1555 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from

1557
1558 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
1559
1560 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
1561 value for non-existent files.
1562
1563 2011-09-11 Eli Zaretskii <eliz@gnu.org>
1564
1565 * fileio.c (Finsert_file_contents): If the file cannot be opened,
1566 set its "size" to -1. This will set the modtime_size field of
1567 the corresponding buffer to -1, which is what
1568 verify-visited-file-modtime expects for files that do not exist.
1569 (Bug#9139)
1570
1571 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
1572
1573 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
1574 here ...
1575 * lisp.h: ... from here. push_key_description is no longer
1576 defined in keyboard.c, so its declaration should not be in
1577 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
1578 logically belongs with push_key_description.
1579
1580 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
1581
1582 * buffer.h: Include <sys/types.h> instead of <time.h>.

1600
1601 2011-09-09 Eli Zaretskii <eliz@gnu.org>

1608 Operate on live windows only.
1609
1610 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
1611

1624
1625 isnan: Fix porting problem to Solaris 10 with bundled gcc.
1626 Without this fix, the command to link temacs failed due to an
1627 undefined symbol __builtin_isnan. This is because
1628 /usr/include/iso/math_c99.h #defines isnan(x) to
1629 __builtin_isnan(x), but the bundled gcc, which identifies itself
1630 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
1631 a __builtin_isnan.
1632 * floatfns.c (isnan): #undef, and then #define to a clone of
1633 what's in data.c.
1634 (Fisnan): Always define, since it's always available now.
1635 (syms_of_floatfns): Always define isnan at the Lisp level.
1636
1637 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
1638
1639 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
1640
1641 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
1642
1643 * fileio.c: Fix bugs with large file offsets (Bug#9428).
1644 The previous code assumed that file offsets (off_t values) fit in
1645 EMACS_INT variables, which is not true on typical 32-bit hosts.
1646 The code messed up by falsely reporting buffer overflow in cases
1647 such as (insert-file-contents "big" nil 1 2) into an empty buffer
1648 when "big" contains more than 2**29 bytes, even though this
1649 inserts just one byte and does not overflow the buffer.
1650 (Finsert_file_contents): Store file offsets as off_t
1651 values, not as EMACS_INT values. Check for overflow when
1652 converting between EMACS_INT and off_t. When checking for
1653 buffer overflow or for overlap, take the offsets into account.
1654 Don't use EMACS_INT for small values where int suffices.
1655 When checking for overlap, fix a typo: ZV was used where
1656 ZV_BYTE was intended.
1657 (Fwrite_region): Don't assume off_t fits into 'long'.
1658 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
1659
1660 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
1661
1662 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
1663
1664 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
1665
1666 sprintf-related integer and memory overflow issues (Bug#9412).
1667
1668 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
1669 (esprintf, exprintf, evxprintf): New functions.
1670 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
1671 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
1672 (modify_event_symbol): Do not assume that the length of
1673 name_alist_or_stem is safe to alloca and fits in int.
1674 (Fexecute_extended_command): Likewise for function name and binding.
1675 (Frecursion_depth): Wrap around reliably on integer overflow.
1676 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
1677 since some callers pass EMACS_INT values.
1678 (Fsingle_key_description): Don't crash if symbol name contains more
1679 than MAX_ALLOCA bytes.
1680 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
1681 (get_minibuffer): Arg is now EMACS_INT, not int.
1682 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
1683 (esprintf, exprintf, evxprintf): New decls.
1684 * window.h (command_loop_level, minibuf_level): Reflect API changes.
1685
1686 * dbusbind.c (signature_cat): New function.
1687 (xd_signature, Fdbus_register_signal):
1688 Do not overrun buffer; instead, report string overflow.
1689
1690 * dispnew.c (add_window_display_history): Don't overrun buffer.
1691 Truncate instead; this is OK since it's just a log.
1692
1693 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
1694 even if the time zone offset is outlandishly large.
1695 Don't mishandle offset == INT_MIN.
1696
1697 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
1698 when creating daemon; the previous buffer-overflow check was incorrect.
1699
1700 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
1701 which has the guts of the old verror function.
1702
1703 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
1704 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
1705
1706 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
1707 (font_unparse_xlfd): Don't blindly alloca long strings.
1708 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
1709 fits in int, when using sprintf. Use single snprintf to count
1710 length of string rather than counting it via multiple sprintfs;
1711 that's simpler and more reliable.
1712 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
1713 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
1714 sprintf, in case result does not fit in int.
1715
1716 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
1717 (fontset_from_font): Print it.
1718
1719 * frame.c (tty_frame_count): Now printmax_t, not int.
1720 (make_terminal_frame, set_term_frame_name): Print it.
1721 (x_report_frame_params): In X, window IDs are unsigned long,
1722 not signed long, so print them as unsigned.
1723 (validate_x_resource_name): Check for implausibly long names,
1724 and don't assume name length fits in 'int'.
1725 (x_get_resource_string): Don't blindly alloca invocation name;
1726 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
1727 not fit in int.
1728
1729 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
1730 (xg_check_special_colors, xg_set_geometry):
1731 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
1732
1733 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
1734 Use esprintf, not sprintf, in case result does not fit in int.
1735
1736 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
1737 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
1738 it as a large positive number.
1739 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
1740 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
1741

1743 in case result does not fit in int.
1744
1745 * print.c (float_to_string): Detect width overflow more reliably.
1746 (print_object): Make sprintf buffer a bit bigger, to avoid potential
1747 buffer overrun. Don't assume list length fits in 'int'. Treat
1748 print length of 0 as 0, not as infinity; to be consistent with other
1749 uses of print length in this function. Don't overflow print length
1750 index. Don't assume hash table size fits in 'long', or that
1751 vectorlike size fits in 'unsigned long'.
1752
1753 * process.c (make_process): Use printmax_t, not int, to format
1754 process-name gensyms.
1755
1756 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
1757
1758 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
1759 to avoid potential buffer overrun.
1760
1761 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
1762 if X resource line is longer than 512 bytes.
1763
1764 * xfns.c (x_window): Make sprintf buffer a bit bigger
1765 to avoid potential buffer overrun.

1771 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
1772
1773 Integer overflow fixes for scrolling, etc.
1774 Without these, Emacs silently mishandles large integers sometimes.
1775 For example, "C-u 4294967297 M-x recenter" was treated as if
1776 it were "C-u 1 M-x recenter" on a typical 64-bit host.
1777
1778 * xdisp.c (try_window_id): Check Emacs fixnum range before
1779 converting to 'int'.
1780
1781 * window.c (window_scroll_line_based, Frecenter):
1782 Check that an Emacs fixnum is in range before assigning it to 'int'.
1783 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
1784 values converted from Emacs fixnums.
1785 (Frecenter): Don't wrap around a line count if it is out of 'int'
1786 range; instead, treat it as an extreme value.
1787 (Fset_window_configuration, compare_window_configurations):
1788 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
1789
1790 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
1791 that can exceed INT_MAX. Check that EMACS_INT value is in range
1792 before assigning it to the (possibly-narrower) index.
1793 (match_limit): Don't assume that a fixnum can fit in 'int'.
1794
1795 * print.c (print_object): Use ptrdiff_t, not int, for index that can
1796 exceed INT_MAX.
1797
1798 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
1799 (Fvertical_motion): Don't wrap around LINES values that don't fit
1800 in 'int'. Instead, treat them as extreme values. This is good
1801 enough for windows, which can't have more than INT_MAX lines anyway.
1802
1803 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
1804
1805 * Require libxml/parser.h to avoid compilation warning.
1806
1807 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
1808
1809 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
1810 since this reportedly can destroy thread storage.
1811
1812 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
1813
1814 * syntax.c (find_defun_start): Update all cache variables if
1815 exiting early (Bug#9401).
1816
1817 2011-08-30 Eli Zaretskii <eliz@gnu.org>
1818
1819 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
1820
1821 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
1822 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
1823 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
1824
1825 * term.c (tty_append_glyph): New function.
1826 (produce_stretch_glyph): Static function and its prototype deleted.
1827
1828 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
1829 Add prototypes.
1830
1831 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
1832
1833 * image.c (parse_image_spec): Check for nonnegative, not for positive,
1834 when checking :margin (Bug#9390).
1835 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
1836 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
1837 so that the name doesn't mislead. All uses changed.
1838
1839 2011-08-28 Johan Bockgård <bojohan@gnu.org>
1840
1841 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
1842 set_tty_hooks.
1843
1844 2011-08-27 Eli Zaretskii <eliz@gnu.org>
1845
1846 * xdisp.c (move_it_to): Don't bail out early when reaching
1847 position beyond to_charpos, if we are scanning backwards.
1848 (move_it_vertically_backward): When DY == 0, make sure we get to
1849 the first character in the line after the newline.
1850
1851 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
1852
1853 * ccl.c: Improve and simplify overflow checking (Bug#9196).
1854 (ccl_driver): Do not generate an out-of-range pointer.
1855 (Fccl_execute_on_string): Remove unnecessary check for
1856 integer overflow, noted by Stefan Monnier in
1857 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
1858 Remove a FIXME that didn't need fixing.
1859 Simplify the newly-introduced buffer reallocation code.
1860
1861 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
1862
1863 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
1864
1865 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
1866
1867 Integer and memory overflow issues (Bug#9196).
1868
1869 * doc.c (get_doc_string): Rework so that
1870 get_doc_string_buffer_size is the actual buffer size, rather than
1871 being 1 less than the actual buffer size; this makes xpalloc more
1872 convenient.
1873
1874 * image.c (x_allocate_bitmap_record, cache_image):
1875 * xselect.c (Fx_register_dnd_atom):
1876 Simplify previous changes by using xpalloc.
1877
1878 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
1879 since either will do and ptrdiff_t is convenient with xpalloc.
1880
1881 * charset.c (charset_table_size)
1882 (struct charset_sort_data.priority): Now ptrdiff_t.
1883 (charset_compare): Don't overflow if priorities differ greatly.
1884 (Fsort_charsets): Don't assume list length fits in int.
1885 Check for size-calculation overflow when allocating sort data.
1886 (syms_of_charset): Allocate an initial charset table that is
1887 just under 64 KiB, to avoid problems with glibc malloc and mmap.
1888
1889 * cmds.c (internal_self_insert): Check for size-calculation overflow.
1890
1891 * composite.h (struct composition.glyph_len): Now int, not unsigned.
1892 The actual value is always <= INT_MAX, and leaving it unsigned made
1893 overflow checking harder.
1894
1895 * dispextern.h (struct glyph_matrix.rows_allocated)
1896 (struct face_cache.size): Now ptrdiff_t, for convenience in use
1897 with xpalloc. The values are still always <= INT_MAX.
1898
1899 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
1900
1901 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
1902 (SAFE_NALLOCA): New macro.
1903
1904 * region-cache.c (struct boundary.pos, find_cache_boundary)
1905 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
1906 (set_cache_region, invalidate_region_cache)
1907 (revalidate_region_cache, know_region_cache, region_cache_forward)
1908 (region_cache_backward, pp_cache):
1909 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
1910 so that ptrdiff_t * can be passed to xpalloc.
1911 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
1912 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
1913 (pp_cache): Don't assume cache_len fits in int.
1914 * region-cache.h: Adjust extern decls to match.
1915
1916 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
1917 EMACS_INT, since either will do, for xpalloc.
1918
1919 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
1920 (xnmalloc, xnrealloc, xpalloc): New functions.
1921
1922 * bidi.c (bidi_shelve_header_size): New constant.
1923 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
1924 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
1925
1926 * bidi.c (bidi_cache_shrink):
1927 * buffer.c (overlays_at, overlays_in, record_overlay_string)
1928 (overlay_strings):
1929 Don't update size of array until after memory allocation succeeds,
1930 because xmalloc/xrealloc may not return.
1931 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
1932 now that we have proper integer overflow checking.
1933 (record_overlay_string, overlay_strings): Catch overflows when
1934 calculating size of overlay_str_buf.
1935
1936 * callproc.c (Fcall_process): Check for size overflow when
1937 calculating size of args2.
1938 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
1939 Normally we prefer signed values, but sticking with ptrdiff_t would
1940 require adding more-complicated checks.
1941
1942 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
1943 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
1944 Redo buffer-overflow calculations to avoid integer overflow.
1945 Add a FIXME comment where memory seems to be over-allocated.
1946
1947 * character.c (Fstring): Check for size-calculation overflow.
1948
1949 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
1950 unnecessary integer overflow. Check for size overflow.
1951 (encode_coding_object): Don't update size until xmalloc succeeds.
1952
1953 * composite.c (get_composition_id): Check for overflow in glyph
1954 length calculations.
1955
1956 Integer and memory overflow fixes for display code.
1957 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
1958 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
1959 (scrolling_window): Check for overflow in size calculations.
1960 (line_draw_cost, realloc_glyph_pool, add_row_entry):
1961 Don't assume glyph table len fits in int.

1963 (row_table_size): Now ptrdiff_t, not int.
1964 (scrolling_window): Avoid overflow in size calculations.
1965 Don't update size until allocation succeeds.
1966 * fns.c (concat): Check for overflow in size calculations.
1967 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
1968 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.

1970
1971 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
1972 (get_doc_string): Check for size calculation overflow.
1973 Don't update size until allocation succeeds.
1974 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
1975 EMACS_INT, where ptrdiff_t will do.
1976 (Fsubstitute_command_keys): Check for string overflow.
1977
1978 * editfns.c (set_time_zone_rule): Don't assume environment length
1979 fits in int.
1980 (message_length): Now ptrdiff_t, not int.
1981 (Fmessage_box): Don't update size until allocation succeeds.
1982 Don't assume message length fits in int.
1983 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
1984
1985 * emacs.c (main): Do not reallocate argv, since there is a null at
1986 the end that can be overwritten, and this way there's no need to
1987 worry about size-calculation overflow.
1988 (sort_args): Check for size-calculation overflow.
1989
1990 * eval.c (init_eval_once, grow_specpdl): Don't update size until
1991 alloc succeeds.
1992 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
1993
1994 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
1995 (x_set_scroll_bar_width, x_figure_window_size):
1996 Check for integer overflow.
1997 (x_set_alpha): Do not assume XINT fits in int.
1998
1999 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
2000 This is for the members text_lines, text_cols, total_lines, total_cols,
2001 where the system imposes an 'int' limit.
2002
2003 * fringe.c (Fdefine_fringe_bitmap):
2004 Don't update size until alloc works.
2005
2006 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
2007 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
2008
2009 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
2010 Check for size-calculation overflow.
2011 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
2012 do, as we prefer signed integers.
2013 (id_to_widget.max_size, id_to_widget.used)
2014 (xg_store_widget_in_map, xg_remove_widget_from_map)
2015 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
2016 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
2017 Use and return ptrdiff_t, not int.
2018 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
2019 * gtkutil.h: Change prototypes to match the above.
2020
2021 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
2022 are duplicate now that they've been promoted to lisp.h.
2023 (x_allocate_bitmap_record, x_alloc_image_color)
2024 (make_image_cache, cache_image, xpm_load):
2025 Don't update size until alloc is done.
2026 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
2027 (x_detect_edges):
2028 Check for size calculation overflow.
2029 (ct_colors_allocated_max): New constant.
2030 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
2031 overflow.
2032
2033 * keyboard.c (read_char, menu_bar_items, tool_bar_items)
2034 (read_char_x_menu_prompt, read_char_minibuf_menu_width)
2035 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
2036 Use ptrdiff_t, not int, to count maps.
2037 (read_char_minibuf_menu_prompt): Check for overflow in size
2038 calculations. Don't update size until allocation succeeds.
2039 Redo calculations to avoid overflow.
2040 * keyboard.h: Change prototypes to match the above.

2067
2068 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
2069 for command line length. Do not attempt to address one before the
2070 beginning of an array, as that's not portable.
2071
2072 * term.c (max_frame_lines): Remove; unused.
2073 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
2074 not int.

2081
2082 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of

2085 until alloc done.
2086
2087 * tparam.c (tparam1): Use ptrdiff_t, not int, for sizes.
2088 Don't update size until alloc done.
2089 Redo size calculations to avoid overflow.
2090 Check for size calculation overflow.
2091 (main) [DEBUG]: Fix typo in invoking tparam1.

2100 Check for size calculation overflow.
2101 (cache_face): Treat size calculation overflows as if they were

2104 * xfns.c (x_encode_text, x_set_name_internal)
2105 (Fx_change_window_property): Use ptrdiff_t, not int, to count

2111 Don't update size until alloc done.
2112

2114 as sprintf is limited to int lengths.
2115
2116 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
2117 (X_LONG_MIN): New macros.
2118 Use them to make the following changes clearer.
2119 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
2120 This change doesn't affect the value now, but it may help remind
2121 future maintainers not to raise the value too much later.
2122 (SELECTION_QUANTUM): Remove, replacing with ...
2123 (selection_quantum): ... new function, which avoids overflow.
2124 All uses changed.
2125 (struct selection_data.size): Now ptrdiff_t, not int, to avoid

2132 (x_reply_selection_request, x_get_window_property)
2133 (receive_incremental_selection, x_property_data_to_lisp):
2134 Redo calculations to avoid overflow.
2135 (x_reply_selection_request): When sending hint, ceiling it at
2136 X_LONG_MAX rather than relying on wraparound overflow to send
2137 something.

2141 (x_get_window_property, receive_incremental_selection)
2142 (lisp_data_to_selection_data, Fx_register_dnd_atom):
2143 Don't store size until memory allocation succeeds.
2144 (x_get_window_property): Plug memory leak on memory exhaustion.
2145 Don't double-block input; malloc is safe here. Don't assume 2**34
2146 - 4 fits in unsigned long. Add an xassert to check
2147 XGetWindowProperty overflow. Be more careful about overflow
2148 calculations, and distinguish size from memory overflow better.
2149 (receive_incremental_selection): When tracing, don't assume
2150 unsigned int is less than INT_MAX.
2151 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
2152 harmful) conversions of unsigned short to int.
2153 (lisp_data_to_selection_data): Don't assume that integers
2154 in the range -65535 through -1 fit in an X unsigned short.
2155 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
2156 result parameters unless successful. Rely on cons_to_unsigned
2157 to report problems with elements; the old code wasn't right anyway.
2158 (x_check_property_data): Check for int overflow; we cannot use
2159 a wider type due to X limits.
2160 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
2161
2162 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
2163
2164 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)
2165 (x_term_init): Check for size calculation overflow.
2166 (x_color_cells): Don't store size until memory allocation succeeds.
2167 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
2168 Don't assume alloca size is less than MAX_ALLOCA.
2169 (x_term_init): Don't assume length fits in int (sprintf is limited
2170 to int size).
2171
2172 Use ptrdiff_t for composition IDs.
2173 * character.c (lisp_string_width):
2174 * composite.c (composition_table_size, n_compositions)
2175 (get_composition_id, composition_gstring_from_id):
2176 * dispextern.h (struct glyph_string.cmp_id, struct composition_it.id):

2191 * image.c (xpm_get_color_table_h):
2192 * lisp.h (hash_lookup, hash_put):
2193 * minibuf.c (Ftest_completion):
2194 Use ptrdiff_t for hash table indexes, not int (which is too
2195 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
2196 32-bit --with-wide-int hosts).
2197
2198 * charset.c (Fdefine_charset_internal): Check for integer overflow.
2199 Add a FIXME comment about memory leaks.
2200 (syms_of_charset): Don't assume xmalloc returns.
2201
2202 Don't assume that stated character widths fit in int.
2203 * character.c (Fchar_width, c_string_width, lisp_string_width):
2204 * character.h (CHAR_WIDTH):
2205 * indent.c (MULTIBYTE_BYTES_WIDTH):
2206 Use sanitize_char_width to avoid undefined and/or bad behavior
2207 with outlandish widths.
2208 * character.h (sanitize_tab_width): Rename from sanitize_width,
2209 now that we have two such functions. All uses changed.
2210 (sanitize_char_width): New inline function.
2211
2212 Don't assume that tab-width fits in int.
2213 * character.h (sanitize_width): New inline function.
2214 (SANE_TAB_WIDTH): New macro.
2215 (ASCII_CHAR_WIDTH): Use it.
2216 * indent.c (sane_tab_width): Remove. All uses replaced by
2217 SANE_TAB_WIDTH (current_buffer).

2219
2220 * fileio.c: Integer overflow issues with file modes.
2221 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
2222
2223 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
2224 Remove unreachable code.
2225 (read_hex, load_charset_map_from_file): Check for integer overflow.
2226
2227 * xterm.c: don't go over XClientMessageEvent limit
2228 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
2229 (x_send_scroll_bar_event): Likewise. Check that the size does not
2230 exceed limits imposed by XClientMessageEvent, as well as the usual
2231 ptrdiff_t and size_t limits.
2232
2233 * keyboard.c: Overflow, signedness and related fixes.
2234 (make_lispy_movement): Use same integer type in forward decl
2235 that is used in the definition.
2236 (read_key_sequence, keyremap_step):
2237 Change bufsize argument back to int, undoing my 2011-03-30 change.
2238 We prefer signed types, and int is wide enough here.
2239 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
2240 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
2241 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
2242 length, not size_t. Use ptrdiff_t for index, not int.
2243 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
2244 possibility of integer overflow.
2245
2246 Overflow, signedness and related fixes for images.

2255 * nsmenu.m (update_frame_tool_bar):
2256 * xdisp.c (calc_pixel_width_or_height):
2257 * xfns.c (image_cache_refcount):
2258 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
2259 on typical 64-bit hosts.
2260
2261 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
2262 (x_bitmap_pixmap, x_create_x_image_and_pixmap):
2263 Omit unnecessary casts to int.

2265 when the callers expect that.
2266 (image_ascent): Redo ascent calculation to avoid int overflow.
2267 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
2268 (lookup_image): Remove unnecessary tests.
2269 (xbm_image_p): Locals are now of int, not EMACS_INT,
2270 since parse_image_check makes sure they fit into int.
2271 (png_load, gif_load, svg_load_image):
2272 Prefer int to unsigned where either will do.
2273 (tiff_handler): New function, combining the cores of the
2274 old tiff_error_handler and tiff_warning_handler.
2275 This function is rewritten to use vsnprintf and thereby avoid
2276 stack buffer overflows. It uses only the features of vsnprintf
2277 that are common to both POSIX and native Microsoft.
2278 (tiff_error_handler, tiff_warning_handler): Use it.
2279 (tiff_load, gif_load, imagemagick_load_image):
2280 Don't assume :index value fits in 'int'.
2281 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
2282 (imagemagick_load_image): Check that crop parameters fit into
2283 the integer types that MagickCropImage accepts. Don't assume
2284 Vimagemagick_render_type has a nonnegative value. Don't assume
2285 size_t fits in 'long'.
2286 (gs_load): Use printmax_t to print the widest integers possible.
2287 Check for integer overflow when computing image height and width.
2288
2289 2011-08-26 Eli Zaretskii <eliz@gnu.org>
2290
2291 * xdisp.c (redisplay_window): Don't force window start if point
2292 will be invisible in the resulting window. (Bug#9324)
2293
2294 2011-08-25 Eli Zaretskii <eliz@gnu.org>
2295
2296 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
2297 the display spec is of the form `(space ...)'.
2298 (handle_display_spec): Return the value returned by
2299 handle_single_display_spec, not just 1 or zero.
2300 (handle_single_display_spec): If the display spec is of the form
2301 `(space ...)', and specifies display in the text area, return 2
2302 rather than 1.
2303 (try_cursor_movement): Check for the need to scroll more
2304 accurately, and prefer exact match for point under bidi.
2305 Don't advance `row' beyond the last row of the window.
2306
2307 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
2308 into disp_prop; all users changed.
2309
2310 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
2311 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
2312 for the text covered by the display property.

2321
2322 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
2323 buffers, return left-to-right.
2324 (set_cursor_from_row): Consider candidate row a win if its glyph
2325 represents a newline and point is on that newline. Fixes cursor
2326 positioning on the newline at EOL of R2L text within L2R
2327 paragraph, and vice versa.
2328 (try_cursor_movement): Check continued rows, in addition to
2329 continuation rows. Fixes unwarranted scroll when point enters a
2330 continued line of R2L text within an L2R paragraph, or vice versa.
2331 (cursor_row_p): Consider the case of point being equal to
2332 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
2333 from the end of a short line to the beginning of a continued line
2334 of R2L text within L2R paragraph.
2335 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
2336 composed characters.
2337
2338 * bidi.c (bidi_check_type): Use xassert.
2339 (bidi_cache_iterator_state): Update the disp_pos and disp_prop_p
2340 members.
2341
2342 2011-08-23 Eli Zaretskii <eliz@gnu.org>

2357
2358 * xdisp.c (redisplay_window): When computing centering_position,
2359 account for the height of the header line. (Bug#8874)
2360
2361 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
2362 instead of CHAR_TO_BYTE. Fixes a crash when a completion
2363 candidate is selected by the mouse, and that candidate has a
2364 composed character under the mouse.
2365
2366 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
2367 coordinates reported by pos-visible-in-window-p for a composed
2368 character in column zero.
2369
2370 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

2374 2011-08-22 Eli Zaretskii <eliz@gnu.org>
2375
2376 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
2377 consider it a hit if to_charpos is anywhere in the range of the
2378 composed buffer positions.
2379
2380 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
2381
2382 * image.c (gif_load): Don't assume that each subimage has the same
2383 dimensions as the base image. Handle disposal method that is
2384 "undefined" by the gif spec (Bug#9335).
2385
2386 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
2387

2390
2391 2011-08-19 Eli Zaretskii <eliz@gnu.org>
2392
2393 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
2394 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
2395 from an Org mode buffer to a Speedbar frame.
2396
2397 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
2398 a composition, take its buffer position from IT->cmp_it.charpos.
2399 Fixes cursor positioning at the beginning of a line that begins
2400 with a composed character.
2401
2402 2011-08-18 Eli Zaretskii <eliz@gnu.org>
2403
2404 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
2405 character bidirectional type, use STRONG_L instead. Fixes crashes
2406 in a buffer produced by `describe-categories'.
2407
2408 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
2409 members before the level stack, so they would be saved and
2410 restored when copying iterator state. Fixes incorrect reordering
2411 around TABs covered by display properties.
2412
2413 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
2414

2424
2425 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
2426 has no `load' handler, try opening the file locally. (Bug#9311)
2427
2428 2011-08-16 Ken Brown <kbrown@cornell.edu>
2429

2433
2434 * xdisp.c (set_cursor_from_row): Don't accept a previous candidate
2435 if it fails the cursor_row_p test. Fixes cursor positioning at ZV.
2436
2437 2011-08-16 Ken Brown <kbrown@cornell.edu>
2438
2439 Fix memory allocation problems in Cygwin build (Bug#9273).

2484
2485 * xdisp.c (move_it_in_display_line_to): Don't invoke
2486 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
2487 ppos_it. Fixes vertical cursor motion when line beginning is
2488 covered by an image. (Bug#9296)
2489
2490 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>

2497 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
2498 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
2499 the event loop. Get status from as_status (Bug#7276).
2500
2501 * nsterm.m (sendEvent): If event is NSApplicationDefined and
2502 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
2503 the event loop (Bug#7276).
2504
2505 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
2506

2525
2526 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
2527
2528 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
2529 (Fnetwork_interface_list): Allocate in increments of bytes instead
2530 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
2531 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
2532 sockaddr.
2533 (struct ifflag_def): notrailers is smart on OSX.
2534 (Fnetwork_interface_info): Handle case when ifr_flags is negative.

2538
2539 * xdisp.c (iterate_out_of_display_property): xassert that
2540 IT->position is set to within IT->object's boundaries. Break from
2541 the loop as soon as EOB is reached; avoids infloops in redisplay
2542 when IT->position is set up wrongly due to some bug.
2543 Set IT->current to match the bidi iterator unconditionally.
2544 (push_display_prop): Allow GET_FROM_STRING as IT->method on
2545 entry. Force push_it to save on the stack the current
2546 buffer/string position, to be restored by pop_it. Fix flags in
2547 the iterator structure wrt the object coming from a display
2548 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
2549 properties. (Bug#9284)
2550
2551 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
2552

2558 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
2559 and LC_VERSION_MIN_MACOSX.
2560 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
2561 (dump_it) [LC_FUNCTION_STARTS]: Use it.
2562
2563 2011-08-08 Eli Zaretskii <eliz@gnu.org>
2564
2565 * xdisp.c (forward_to_next_line_start): Allow to use the
2566 no-display-properties-and-no-overlays under bidi display.
2567 Set disp_pos in the bidi iterator to avoid searches for display
2568 properties and overlays.
2569
2570 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
2571
2572 * editfns.c (Fset_time_zone_rule): Document relationship with the
2573 setenv function.
2574
2575 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
2576 the font entity extracted from the cache (Bug#8109).
2577
2578 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
2579
2580 * composite.c (autocmp_chars): Don't reset point. That is done by
2581 restore_point_unwind (Bug#5984).
2582
2583 2011-08-07 Juri Linkov <juri@jurta.org>
2584
2585 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'

2589
2590 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
2591 display property strides EOL and includes a newline, as in
2592 longlines-mode. (Bug#9254)
2593 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
2594 word-wrap under bidirectional display. (Bug#9224)
2595
2596 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
2597 is non-zero, even if the data buffer is NULL. Fixes a crash in
2598 vertical-motion with longlines-mode. (Bug#9254)
2599
2600 2011-08-05 Eli Zaretskii <eliz@gnu.org>
2601
2602 * bidi.c <bidi_cache_total_alloc>: Now static.
2603 (bidi_initialize): Initialize bidi_cache_total_alloc.
2604
2605 * xdisp.c (display_line): Release buffer allocated for shelved bidi
2606 cache. (Bug#9221)
2607
2608 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
2609 amount allocated this far in `bidi_cache_total_alloc'.
2610 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
2611 non-zero, only free the data buffer without restoring the cache
2612 contents. All callers changed.
2613
2614 * dispextern.h (bidi_unshelve_cache): Update prototype.
2615
2616 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
2617 (move_it_in_display_line, move_it_to)
2618 (move_it_vertically_backward, move_it_by_lines): Replace the call
2619 to xfree to an equivalent call to bidi_unshelve_cache.
2620 (move_it_in_display_line_to): Fix logic of returning
2621 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
2622
2623 2011-08-05 Eli Zaretskii <eliz@gnu.org>
2624
2625 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
2626 came from a string character with a `cursor' property. (Bug#9229)
2627
2628 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
2629
2630 * Makefile.in (LIB_PTHREAD): New variable.
2631 (LIBES): Add LIB_PTHREAD (Bug#9216).
2632
2633 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
2634 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
2635
2636 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
2637
2638 * regex.c (re_iswctype): Remove some redundant boolean conversions.
2639
2640 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
2641
2642 * xterm.c (x_find_topmost_parent): New function.
2643 (x_set_frame_alpha): Find topmost parent window with
2644 x_find_topmost_parent and set the property there also (bug#9181).
2645 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
2646
2647 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
2648
2649 * callproc.c (Fcall_process): Avoid vfork clobbering
2650 the local vars buffer, coding_systems, current_dir.
2651
2652 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
2653
2654 * keymap.c (Fmake_composed_keymap): Move to subr.el.
2655
2656 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
2657
2658 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
2659 so that it is not optimized away.
2660
2661 * xdisp.c (compute_display_string_pos): Remove unused local.
2662
2663 2011-08-02 Eli Zaretskii <eliz@gnu.org>
2664
2665 Fix slow cursor motion and scrolling in large buffers with
2666 selective display, like Org Mode buffers. (Bug#9218)
2667
2668 * dispextern.h (struct bidi_it): New member disp_prop_p.
2669
2670 * xdisp.c: Remove one-slot cache of display string positions.
2671 (compute_display_string_pos): Accept an additional argument
2672 DISP_PROP_P; callers changed. Scan at most 5K characters forward
2673 for a display string or property. If found, set DISP_PROP_P
2674 non-zero.
2675
2676 * bidi.c (bidi_fetch_char): Accept an additional argument
2677 DISP_PROP_P, and pass it to compute_display_string_pos.
2678 Only handle text covered by a display string if DISP_PROP_P is returned
2679 non-zero. All callers of bidi_fetch_char changed.
2680
2681 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
2682
2683 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
2684
2685 2010-12-03 Don March <don@ohspite.net>
2686
2687 * keymap.c (Fdefine_key): Fix non-prefix key error message when
2688 last character M-[char] is translated to ESC [char] (bug#7541).
2689
2690 2011-08-02 Kenichi Handa <handa@m17n.org>
2691
2692 * lisp.h (uniprop_table): Extern it.
2693
2694 * chartab.c (uniprop_table): Make it non-static.
2695
2696 2011-08-01 Eli Zaretskii <eliz@gnu.org>
2697
2698 * xdisp.c (forward_to_next_line_start): Accept additional argument
2699 BIDI_IT_PREV, and store into it the state of the bidi iterator had
2700 on the newline.
2701 (reseat_at_next_visible_line_start): Use the bidi iterator state
2702 returned by forward_to_next_line_start to restore the state of
2703 it->bidi_it after backing up to previous newline. (Bug#9212)
2704
2705 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
2706
2707 * regex.c (re_comp): Protoize.
2708 (re_exec): Fix return type.
2709 (regexec): Fix type of `ret'. (Bug#9203)
2710
2711 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
2712
2713 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
2714 This is needed if max-image-size is a floating-point number.
2715
2716 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
2717
2718 * print.c (print_object): Print empty symbol as ##.
2719
2720 * lread.c (read1): Read ## as empty symbol.
2721
2722 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
2723
2724 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
2725 setting frame foreground color (Bug#9175).
2726 (x_set_background_color): Likewise.
2727
2728 * nsmenu.m (-setText): Size tooltip dimensions precisely to
2729 contents (Bug#9176).
2730 (EmacsTooltip -init): Remove bezels and add shadows to
2731 tooltip windows.
2732
2733 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
2734 or scroll bar (Bug#8470).
2735
2736 * nsfont.m (nsfont_open): Remove assignment to voffset and
2737 unnecessary vars hshink, expand, hd, full_height, min_height.
2738 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
2739
2740 * nsterm.h (nsfont_info): Remove voffset field.
2741
2742 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
2743
2744 Implement strike-through and overline on NextStep (Bug#8863).
2745
2746 * nsfont.m (nsfont_open): Use underline position provided by font,
2747 instead of hard-coded value of 2.
2748 (nsfont_draw): Call ns_draw_text_decoration instead.
2749
2750 * nsterm.h: Add declaration for ns_draw_text_decoration.
2751
2752 * nsterm.m (ns_draw_text_decoration): New function for drawing
2753 underline, overline, and strike-through.
2754 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
2755 ns_draw_text_decoration. Change treatment of cursor drawing to
2756 accommodate underlining, etc.
2757
2758 2011-07-28 Eli Zaretskii <eliz@gnu.org>
2759
2760 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
2761 default.
2762
2763 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
2764
2765 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
2766 Without this fix, if a signal arrives just after memory fills up,
2767 'malloc' might be invoked reentrantly.
2768
2769 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
2770 In other words, assume that every image size is allowed, on non-X
2771 hosts. This assumption is probably wrong, but it lets Emacs compile.
2772
2773 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
2774
2775 * regex.c (re_iswctype): Convert return values to boolean.
2776
2777 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
2778
2779 * xdisp.c (compute_display_string_pos): Don't use cached display
2780 string position if the buffer had its restriction changed.
2781 (Bug#9184)
2782
2783 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
2784
2785 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
2786
2787 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
2788
2789 Integer signedness and overflow and related fixes. (Bug#9079)
2790
2791 * bidi.c: Integer size and overflow fixes.
2792 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
2793 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
2794 (bidi_cache_find_level_change, bidi_cache_ensure_space)
2795 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
2796 (bidi_find_other_level_edge):
2797 Use ptrdiff_t instead of EMACS_INT where either will do.
2798 This works better on 32-bit hosts configured --with-wide-int.
2799 (bidi_cache_ensure_space): Check for size-calculation overflow.
2800 Use % rather than repeated addition, for better worst-case speed.
2801 Don't set bidi_cache_size until after xrealloc returns, because it
2802 might not return.
2803 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
2804 (bidi_cache_ensure_space): Also check that the bidi cache size
2805 does not exceed that of the largest Lisp string or buffer. See Eli
2806 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
2807
2808 * alloc.c (__malloc_size_t): Remove.
2809 All uses replaced by size_t. See Andreas Schwab's note
2810 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
2811
2812 * image.c: Improve checking for integer overflow.
2813 (check_image_size): Assume that f is nonnull, since
2814 it is always nonnull in practice. This is one less thing to
2815 worry about when checking for integer overflow later.
2816 (x_check_image_size): New function, which checks for integer
2817 overflow issues inside X.
2818 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
2819 This removes the need for a memory_full check.
2820 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
2821 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
2822 (xbm_read_bitmap_data): Change locals back to 'int', since
2823 their values must fit in 'int'.
2824 (xpm_load_image, png_load, tiff_load):
2825 Invoke x_create_x_image_and_pixmap earlier,
2826 to avoid much needless work if the image is too large.
2827 (tiff_load): Treat overly large images as if
2828 x_create_x_image_and_pixmap failed, not as malloc failures.
2829 (gs_load): Use x_check_image_size.
2830
2831 * gtkutil.c: Omit integer casts.
2832 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
2833 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
2834
2835 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
2836
2837 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
2838 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
2839 would wrongly return t on a 64-bit host.
2840
2841 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
2842 The plain *_OVERFLOW macros run afoul of GCC bug 49705
2843 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
2844 and therefore cause GCC to emit a bogus diagnostic in some cases.
2845
2846 * image.c: Integer signedness and overflow and related fixes.
2847 This is not an exhaustive set of fixes, but it's time to
2848 record what I've got.
2849 (lookup_pixel_color, check_image_size): Remove redundant decls.
2850 (check_image_size): Don't assume that arbitrary EMACS_INT values
2851 fit in 'int', or that arbitrary 'double' values fit in 'int'.
2852 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
2853 (tiff_load, imagemagick_load_image):
2854 Check for overflow in size calculations.
2855 (x_create_x_image_and_pixmap): Remove unnecessary test for
2856 xmalloc returning NULL; that can't happen.
2857 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
2858 (xpm_color_bucket): Use better integer hashing function.
2859 (xpm_cache_color): Don't possibly over-allocate memory.
2860 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
2861 (gif_memory_source):
2862 Use ptrdiff_t, not int or size_t, to record sizes.
2863 (png_load): Don't assume values greater than 2**31 fit in 'int'.
2864 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
2865 either works, as we prefer signed integers.
2866 (tiff_read_from_memory, tiff_write_from_memory):
2867 Return tsize_t, not size_t, since that's what the TIFF API wants.
2868 (tiff_read_from_memory): Don't fail simply because the read would
2869 go past EOF; instead, return a short read.
2870 (tiff_load): Omit no-longer-needed casts.
2871 (Fimagemagick_types): Don't assume size fits into 'int'.
2872
2873 Improve hashing quality when configured --with-wide-int.
2874 * fns.c (hash_string): New function, taken from sxhash_string.
2875 Do not discard information about ASCII character case; this
2876 discarding is no longer needed.
2877 (sxhash-string): Use it. Change sig to match it. Caller changed.
2878 * lisp.h: Declare it.
2879 * lread.c (hash_string): Remove, since we now use fns.c's version.
2880 The fns.c version returns a wider integer if --with-wide-int is
2881 specified, so this should help the quality of the hashing a bit.
2882
2883 * emacs.c: Integer overflow minor fix.
2884 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
2885 Define only if GNU_LINUX.
2886 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
2887
2888 * dispnew.c: Integer signedness and overflow fixes.
2889 Remove unnecessary forward decls, that were a maintenance hassle.
2890 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
2891 All uses changed.
2892 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
2893 (scrolling_window): Use ptrdiff_t, not int, for byte count.
2894 (prepare_desired_row, line_draw_cost):
2895 Use int, not unsigned, where either works.
2896 (save_current_matrix, restore_current_matrix):
2897 Use ptrdiff_t, not size_t, where either works.
2898 (init_display): Check for overflow more accurately, and without
2899 relying on undefined behavior.
2900
2901 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
2902 Remove, replacing with the new symbols in lisp.h. All uses changed.
2903 * fileio.c (make_temp_name):
2904 * filelock.c (lock_file_1, lock_file):
2905 * xdisp.c (message_dolog):
2906 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
2907 Use pMd etc. instead.
2908 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
2909 replacing the pWIDE etc. symbols removed from editfns.c.
2910
2911 * keyboard.h (num_input_events): Now uintmax_t.
2912 This is (very slightly) less likely to mess up due to wraparound.
2913 All uses changed.
2914
2915 * buffer.c: Integer signedness fixes.
2916 (alloc_buffer_text, enlarge_buffer_text):
2917 Use ptrdiff_t rather than size_t when either will do, as we prefer
2918 signed integers.
2919
2920 * alloc.c: Integer signedness and overflow fixes.
2921 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
2922 (__malloc_size_t): Default to size_t, not to int.
2923 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
2924 (Fgarbage_collect, mark_object_loop_halt, mark_object):
2925 Prefer ptrdiff_t to size_t when either would do, as we prefer
2926 signed integers.
2927 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
2928 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
2929 Now const. Initialize with values that are in range even if char
2930 is signed.
2931 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
2932 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
2933 These functions do the right thing with sizes > 2**32.
2934 (check_depth): Now ptrdiff_t, not int.
2935 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
2936 Adjust to new way of storing sizes. Check for size overflow bugs
2937 in rest of code.
2938 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
2939 slightly wrong anyway, as it missed one instance of
2940 XMALLOC_OVERRUN_CHECK_OVERHEAD.
2941 (refill_memory_reserve): Omit needless cast to size_t.
2942 (mark_object_loop_halt): Mark as externally visible.
2943
2944 * xselect.c: Integer signedness and overflow fixes.
2945 (Fx_register_dnd_atom, x_handle_dnd_message):
2946 Use ptrdiff_t, not size_t, since we prefer signed.
2947 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
2948 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
2949 x_dnd_atoms_size and x_dnd_atoms_length.
2950
2951 * doprnt.c: Prefer signed to unsigned when either works.
2952 * eval.c (verror):
2953 * doprnt.c (doprnt):
2954 * lisp.h (doprnt):
2955 * xdisp.c (vmessage):
2956 Use ptrdiff_t, not size_t, when using or implementing doprnt,
2957 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
2958 prefer signed arithmetic to avoid comparison confusion.
2959 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
2960 but is a bit tricky.
2961
2962 Assume freestanding C89 headers, string.h, stdlib.h.
2963 * data.c, doprnt.c, floatfns.c, print.c:
2964 Include float.h unconditionally.
2965 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
2966 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
2967 * regex.c: Likewise for stddef.h, string.h.
2968 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
2969 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
2970 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
2971 (STDC_HEADERS): Remove obsolete defines.
2972 * sysdep.c: Include limits.h unconditionally.
2973
2974 Assume support for memcmp, memcpy, memmove, memset.
2975 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
2976 * regex.c (memcmp, memcpy):
2977 Remove; we assume C89 now.
2978
2979 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
2980 (__malloc_safe_bcopy): Remove; no longer needed.
2981
2982 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
2983 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
2984 well either way, and we prefer signed to unsigned.
2985
2986 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
2987
2988 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
2989 closes the connection while we're reading (bug#9182).
2990
2991 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
2992
2993 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
2994 are specified (Bug#9168).
2995
2996 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
2997
2998 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
2999 Found by GCC static checking and --with-wide-int on a 32-bit host.
3000
3001 2011-07-25 Eli Zaretskii <eliz@gnu.org>
3002
3003 * xdisp.c (compute_display_string_pos): Fix logic of caching
3004 previous display string position. Initialize cached_prev_pos to
3005 -1. Fixes slow-down at the beginning of a buffer.
3006
3007 2011-07-24 Eli Zaretskii <eliz@gnu.org>
3008
3009 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
3010 for attrs[LFACE_FONTSET_INDEX].
3011
3012 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
3013
3014 * xml.c (parse_region): Remove unused local
3015 that was recently introduced.
3016
3017 2011-07-23 Eli Zaretskii <eliz@gnu.org>
3018
3019 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
3020 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
3021
3022 * xdisp.c (move_it_in_display_line_to): Record the best matching
3023 position for TO_CHARPOS while scanning the line, and restore it on
3024 exit if none of the characters scanned was an exact match.
3025 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
3026 when exact match is impossible due to invisible text, and the
3027 lines are truncated.
3028
3029 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
3030
3031 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
3032 for OSX >= 10.7.
3033
3034 2011-07-22 Eli Zaretskii <eliz@gnu.org>
3035
3036 Fix a significant slow-down of cursor motion with C-n, C-p,
3037 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
3038 auto-repeat under bidi redisplay in fontified buffers.
3039 * xdisp.c (compute_stop_pos_backwards): New function.
3040 (next_element_from_buffer): Call compute_stop_pos_backwards to
3041 find a suitable prev_stop when we find ourselves before
3042 base_level_stop.
3043 (reseat): Don't look for prev_stop, as that could mean a very long
3044 run.
3045 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
3046 <cached_disp_overlay_modiff>: Cache for last found display string
3047 position.
3048 (compute_display_string_pos): Return the cached position if asked
3049 about the same buffer in the same area of character positions, and
3050 the buffer wasn't changed since the time the display string
3051 position was cached.
3052
3053 2011-07-22 Eli Zaretskii <eliz@gnu.org>
3054
3055 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
3056 is an integer, which is important for empty lines. (Bug#9149)
3057
3058 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
3059
3060 * frame.c (Fmodify_frame_parameters): In tty case, update the
3061 default face if necessary (Bug#4238).
3062
3063 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
3064
3065 * editfns.c (Fstring_to_char): No need to explain what a character
3066 is in the docstring (Bug#6576).
3067
3068 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
3069
3070 * xml.c (parse_region): Make sure we always return a tree.
3071
3072 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
3073
3074 * xml.c (parse_region): If a document contains only comments,
3075 return that, too.
3076
3077 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
3078
3079 * xml.c (make_dom): Return comments, too.
3080
3081 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
3082
3083 Port to OpenBSD.
3084 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
3085 and the surrounding thread.
3086 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
3087 rather than fgets, and retry after EINTR. Otherwise, 'emacs
3088 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
3089 timer goes off.
3090 * s/openbsd.h (BROKEN_SIGIO): Define.
3091 * unexelf.c (unexec) [__OpenBSD__]:
3092 Don't update the .mdebug section of the Alpha COFF symbol table.
3093
3094 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
3095
3096 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
3097 (bug#8460).
3098
3099 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
3100
3101 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
3102 This fixes some race conditions on the permissions of any newly
3103 created file.
3104
3105 * alloc.c (valid_pointer_p): Use pipe, not open.
3106 This fixes some permissions issues when debugging.
3107
3108 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
3109 If fchown fails to set both uid and gid, try to set just gid,
3110 as that is sometimes allowed. Adjust the file's mode to eliminate
3111 setuid or setgid bits that are inappropriate if fchown fails.
3112
3113 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
3114
3115 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
3116 to compare Lisp_Objects.
3117 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
3118 global_gnutls_log_level, don't mistake it for a Lisp_Object.
3119 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
3120
3121 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
3122
3123 * lread.c (read_integer): Unread even EOF character.
3124 (read1): Likewise. Properly record start position of symbol.
3125
3126 * lread.c (read1): Read `#:' as empty uninterned symbol if no
3127 symbol character follows.
3128
3129 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
3130
3131 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
3132 This works around a problem with the previous change to Fcopy_file.
3133 Recent glibc declares fchown with __attribute__((warn_unused_result)),
3134 and without this change, GCC might complain about discarding
3135 fchown's return value.
3136
3137 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
3138
3139 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
3140
3141 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
3142
3143 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
3144
3145 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
3146
3147 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
3148 it's used from the C level.
3149
3150 * process.c: Use the same condition for POLL_FOR_INPUT in both
3151 keyboard.c and process.c (bug#1858).
3152
3153 2011-07-09 Lawrence Mitchell <wence@gmx.li>
3154
3155 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
3156 (Fgnutls_boot): Use it.
3157
3158 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
3159
3160 * doc.c (Fsubstitute_command_keys): Revert last change.
3161
3162 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
3163
3164 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
3165 quotes the next character, and doesn't affect other longer
3166 sequences (bug#8935).
3167
3168 * lread.c (syms_of_lread): Clarify that is isn't only
3169 `eval-buffer' and `eval-defun' that's affected by
3170 `lexical-binding' (bug#8460).
3171
3172 2011-07-15 Eli Zaretskii <eliz@gnu.org>
3173
3174 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
3175 bidi redisplay when a line includes both an image and is truncated.
3176
3177 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
3178
3179 Fix minor problems found by static checking.
3180 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
3181 (elsz): Now a signed constant, not a size_t var. We prefer signed
3182 types to unsigned, to avoid integer comparison confusion. Without
3183 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
3184 "cannot optimize loop, the loop counter may overflow", a symptom
3185 of the confusion.
3186 * indent.c (Fvertical_motion): Mark locals as initialized.
3187 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
3188
3189 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
3190
3191 * search.c (Fre_search_backward): Mention `case-fold-search' in
3192 all the re_search_* functions (bug#8138).
3193
3194 * keyboard.c (Fopen_dribble_file): Document when the file is
3195 closed (bug#8056).
3196
3197 2011-07-14 Eli Zaretskii <eliz@gnu.org>
3198
3199 * bidi.c (bidi_dump_cached_states): Fix format of displaying
3200 bidi_cache_idx.
3201
3202 Support bidi reordering of display and overlay strings.
3203 * xdisp.c (compute_display_string_pos)
3204 (compute_display_string_end): Accept additional argument STRING.
3205 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
3206 (reseat_to_string): Initialize bidi_it->string.s and
3207 bidi_it->string.schars.
3208 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
3209 NULL (avoids a crash in bidi_paragraph_init).
3210 Initialize itb.string.lstring.
3211 (init_iterator): Call bidi_init_it only of a valid
3212 buffer position was specified. Initialize paragraph_embedding to
3213 L2R.
3214 (reseat_to_string): Initialize the bidi iterator.
3215 (display_string): If we need to ignore text properties of
3216 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
3217 original value of -1 will not work with bidi.)
3218 (compute_display_string_pos): First arg is now struct
3219 `text_pos *'; all callers changed. Support display properties on
3220 Lisp strings.
3221 (compute_display_string_end): Support display properties on Lisp
3222 strings.
3223 (init_iterator, reseat_1, reseat_to_string): Initialize the
3224 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
3225 when iterating on a string not from display properties).
3226 (compute_display_string_pos, compute_display_string_end):
3227 Fix calculation of the object to scan. Fixes an error when using
3228 arrow keys.
3229 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
3230 base_level_stop; instead, set base_level_stop to BEGV.
3231 Fixes crashes in vertical-motion.
3232 (next_element_from_buffer): Improve commentary for when
3233 the iterator is before prev_stop.
3234 (init_iterator): Initialize bidi_p from the default value of
3235 bidi-display-reordering, not from buffer-local value. Use the
3236 buffer-local value only if initializing for buffer iteration.
3237 (handle_invisible_prop): Support invisible properties on strings
3238 that are being bidi-reordered.
3239 (set_iterator_to_next): Support bidi reordering of C strings and
3240 Lisp strings.
3241 (next_element_from_string): Support bidi reordering of Lisp
3242 strings.
3243 (handle_stop_backwards): Support Lisp strings as well.
3244 (display_string): Support display of R2L glyph rows.
3245 Use IT_STRING_CHARPOS when displaying from a Lisp string.
3246 (init_iterator): Don't initialize it->bidi_p for strings
3247 here.
3248 (reseat_to_string): Initialize it->bidi_p for strings here.
3249 (next_element_from_string, next_element_from_c_string)
3250 (next_element_from_buffer): Add xassert's for correspondence
3251 between IT's object being iterated and it->bidi_it.string
3252 structure.
3253 (face_before_or_after_it_pos): Support bidi iteration.
3254 (next_element_from_c_string): Handle the case of the first string
3255 character that is not the first one in the visual order.
3256 (get_visually_first_element): New function, refactored from common
3257 parts of next_element_from_buffer, next_element_from_string, and
3258 next_element_from_c_string.
3259 (tool_bar_lines_needed, redisplay_tool_bar)
3260 (display_menu_bar): Force left-to-right direction. Add a FIXME
3261 comment for making that be controlled by a user option.
3262 (push_it, pop_it): Save and restore the state of the
3263 bidi iterator. Save and restore the bidi_p flag.
3264 (pop_it): Iterate out of display property for string iteration as
3265 well.
3266 (iterate_out_of_display_property): Support iteration over strings.
3267 (handle_single_display_spec): Set up it->bidi_it for iteration
3268 over a display string, and call bidi_init_it.
3269 (handle_single_display_spec, next_overlay_string)
3270 (get_overlay_strings_1, push_display_prop): Set up the bidi
3271 iterator for displaying display or overlay strings.
3272 (forward_to_next_line_start): Don't use the shortcut if
3273 bidi-iterating.
3274 (back_to_previous_visible_line_start): If handle_display_prop
3275 pushed the iterator stack, restore the internal state of the bidi
3276 iterator by calling bidi_pop_it same number of times.
3277 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
3278 and we are bidi-iterating, don't decrement the iterator position;
3279 instead, set the first_elt flag in the bidi iterator, to produce
3280 the same effect.
3281 (reseat_1): Remove redundant setting of string_from_display_prop_p.
3282 (push_display_prop): xassert that we are iterating a buffer.
3283 (push_it, pop_it): Save and restore paragraph_embedding member.
3284 (handle_single_display_spec, next_overlay_string)
3285 (get_overlay_strings_1, reseat_1, reseat_to_string)
3286 (push_display_prop): Set up the `unibyte' member of bidi_it.string
3287 correctly. Don't assume unibyte strings are not bidi-reordered.

3289 (compute_display_string_end): Fix handling the case of C string.
3290 (push_it, pop_it): Save and restore from_disp_prop_p.

3294 (pop_it): Call iterate_out_of_display_property only if we are
3295 popping after iteration over a string that came from a display
3296 property. Fix a typo in popping stretch info. Add an assertion
3297 for verifying that the iterator position is in sync with the bidi
3298 iterator.
3299 (handle_single_display_spec, get_overlay_strings_1)
3300 (push_display_prop): Fix initialization of paragraph direction for
3301 string when that of the parent object is not yet determined.
3302 (reseat_1): Call bidi_init_it to resync the bidi
3303 iterator with IT's position. (Bug#7616)
3304 (find_row_edges): If ROW->start.pos gives position
3305 smaller than min_pos, use it as ROW->minpos. (Bug#7616)
3306 (handle_stop, back_to_previous_visible_line_start, reseat_1):
3307 Reset the from_disp_prop_p flag.
3308 (SAVE_IT, RESTORE_IT): New macros.
3309 (pos_visible_p, face_before_or_after_it_pos)
3310 (back_to_previous_visible_line_start)
3311 (move_it_in_display_line_to, move_it_in_display_line)
3312 (move_it_to, move_it_vertically_backward, move_it_by_lines)
3313 (try_scrolling, redisplay_window, display_line): Use them when
3314 saving a temporary copy of the iterator and restoring it back.
3315 (back_to_previous_visible_line_start, reseat_1)
3316 (init_iterator): Empty the bidi cache "stack".
3317 (move_it_in_display_line_to): If iterator ended up at
3318 EOL, but we never saw any buffer positions smaller than
3319 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
3320 motion in bidi-reordered lines.
3321 (move_it_in_display_line_to): Record prev_method and prev_pos
3322 immediately before the call to set_iterator_to_next. Fixes cursor
3323 motion in bidi-reordered lines with stretch glyphs and strings
3324 displayed in margins. (Bug#8133) (Bug#8867)
3325 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
3326 TO_CHARPOS.
3327 (pos_visible_p): Support positions in bidi-reordered lines.
3328 Save and restore bidi cache.
3329
3330 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.
3331 (bidi_paragraph_info): Delete unused struct.
3332 (bidi_cache_idx, bidi_cache_last_idx): Declare EMACS_INT.
3333 (bidi_cache_start): New variable.

3335 to zero.
3336 (bidi_cache_fetch_state, bidi_cache_search)
3337 (bidi_cache_find_level_change, bidi_cache_iterator_state)
3338 (bidi_cache_find, bidi_peek_at_next_level)
3339 (bidi_level_of_next_char, bidi_find_other_level_edge)
3340 (bidi_move_to_visually_next): Compare cache index with
3341 bidi_cache_start rather than with zero.
3342 (bidi_fetch_char): Accept new argument STRING; all callers
3343 changed. Support iteration over a string. Support strings with
3344 display properties. Support unibyte strings. Fix the type of
3345 `len' according to what STRING_CHAR_AND_LENGTH expects.
3346 (bidi_paragraph_init, bidi_resolve_explicit_1)
3347 (bidi_resolve_explicit, bidi_resolve_weak)
3348 (bidi_level_of_next_char, bidi_move_to_visually_next):
3349 Support iteration over a string.
3350 (bidi_set_sor_type, bidi_resolve_explicit_1)
3351 (bidi_resolve_explicit, bidi_type_of_next_char): ignore_bn_limit

3362 the test for valid cached positions. Fix the logic for looking up
3363 the sentinel state in the cache. GCPRO the Lisp string we are
3364 iterating.
3365 (bidi_push_it, bidi_pop_it): New functions.
3366 (bidi_initialize): Initialize the bidi cache start stack pointer.
3367 (bidi_cache_ensure_space): New function, refactored from part of
3368 bidi_cache_iterator_state. Don't assume the required size is just
3369 one BIDI_CACHE_CHUNK away.

3442
3443 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
3444 The old code sometimes used this field without initializing it.
3445
3446 * alloc.c (gc_sweep): Don't read past end of array.
3447 In theory, the old code could also have corrupted Emacs internals,
3448 though it'd be very unlikely.
3449
3450 2011-07-12 Andreas Schwab <schwab@linux-m68k.org>
3451
3452 * character.c (Fcharacterp): Don't advertise optional ignored

3548
3549 2011-07-08 Paul Eggert <eggert@cs.ucla.edu>
3550
3551 Use pthread_sigmask, not sigprocmask (Bug#9010).
3552 sigprocmask is portable only for single-threaded applications, and
3553 Emacs can be multi-threaded when it uses GTK.

3751
3752 Random fixes. E.g., (random) never returned negative values.
3753 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
3754 subseconds part to the entropy, as that's a bit more random.
3755 Prefer signed to unsigned, since the signedness doesn't matter and
3756 in general we prefer signed. When given a limit, use a
3757 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
3758 latter isn't right if USE_2_TAGS_FOR_INTS.
3759 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
3760 not 0..VALMASK. Don't discard "excess" bits that random () returns.

3770 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
3771
3772 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
3773 This is more efficient than Ffile_directory_p and avoids a minor race.
3774
3775 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
3776
3777 * buffer.c (Foverlay_put): Say what the return value is

3784 error be more correct.

3905 * eval.c (struct backtrace): Simplify and port the data structure.
3906 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
3907 signed bit field, as this assumption is not portable and it makes

3909 "char debug_on_exit : 1" as this is not portable either; instead,
3910 use the portable "unsigned int debug_on_exit : 1". Remove unused
3911 member evalargs. Remove obsolete comments about cc bombing out.

3994
3995 * bidi.c (bidi_paragraph_init): Test for ZV_BYTE before calling
3996 bidi_at_paragraph_end, since fast_looking_at doesn't like to be

4098 (read_integer): Radix is now EMACS_INT, not int,
4099 to improve quality of diagnostics for out-of-range radices.
4100 Calculate buffer size correctly for out-of-range radices.
4101 (read1): Check for integer overflow in radices, and in
4102 read-circle numbers.
4103 (read_escape): Avoid int overflow.
4104 (Fload, openp, read_buffer_size, read1)
4105 (substitute_object_recurse, read_vector, read_list, map_obarray):
4106 Use ptrdiff_t, not int, for sizes.

4127
4128 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
4129 The following patches are for when GLYPH_DEBUG && !XASSERT.
4130 * dispextern.h (trace_redisplay_p, dump_glyph_string):
4131 * dispnew.c (flush_stdout):
4132 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
4133 Mark as externally visible.
4134 * dispnew.c (check_window_matrix_pointers): Now static.
4135 * dispnew.c (window_to_frame_vpos):
4136 * xfns.c (unwind_create_frame):
4137 * xterm.c (x_check_font): Remove unused local.
4138 * scroll.c (CHECK_BOUNDS):
4139 * xfaces.c (cache_fache): Rename local to avoid shadowing.
4140 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
4141 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
4142 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
4143 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
4144 Now static.
4145 (debug_method_add): Use va_list and vsprintf rather than relying
4146 on undefined behavior with wrong number of arguments.
4147 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
4148 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
4149 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
4150 since we're not interested in debugging glyphs with old libraries.
4151 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
4152 GCC 4.6.0's static checking.
4153
4154 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
4155

4174 Use ptrdiff_t, not int, for bitmap indexes.
4175 (x_allocate_bitmap_record): Check for size overflow.
4176 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
4177
4178 Use ptrdiff_t, not int, for overlay counts.

4187 (mouse_face_overlay_overlaps, Foverlays_in):
4188 Use ptrdiff_t, not int, for sizes.
4189 (overlays_at, overlays_in): Check for size-calculation overflow.
4190
4191 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
4192
4193 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
4194 (x_session_initialize): Do not assume string length fits in int.
4195
4196 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
4197 This is unlikely, but can occur if DPI is outlandish.
4198
4199 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
4200 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
4201
4202 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
4203 * xrdb.c (magic_file_p, search_magic_path):
4204 Omit last arg SUFFIX; it was always 0. All callers changed.
4205 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
4206
4207 * xfont.c (xfont_match): Avoid need for strlen.
4208
4209 * xfns.c: Don't assume strlen fits in int.
4210 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
4211
4212 * xdisp.c (message_log_check_duplicate): Return intmax_t,
4213 not unsigned long, as we prefer signed integers. All callers changed.
4214 Detect integer overflow in repeat count.
4215 (message_dolog): Don't assume print length fits in 39 bytes.
4216 (display_mode_element): Don't assume strlen fits in int.
4217
4218 * termcap.c: Don't assume sizes fit in int and never overflow.
4219 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
4220 (gobble_line): Check for size-calculation overflow.
4221
4222 * minibuf.c (Fread_buffer):
4223 * lread.c (intern, intern_c_string):
4224 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
4225 Don't assume string length fits in int.
4226
4227 * keyboard.c (parse_tool_bar_item):
4228 * gtkutil.c (style_changed_cb): Avoid need for strlen.
4229
4230 * font.c: Don't assume string length fits in int.
4231 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
4232 Use ptrdiff_t, not int.
4233 (font_intern_prop): Don't assume string length fits in int.
4234 Don't assume integer property fits in fixnum.
4235 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
4236
4237 * filelock.c: Fix some buffer overrun and integer overflow issues.
4238 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
4239 Reformulate so as not to need the command string.
4240 Invoke gzip -cd rather than gunzip, as it's more portable.
4241 (lock_info_type, lock_file_1, lock_file):
4242 Don't assume pid_t and time_t fit in unsigned long.
4243 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
4244 (current_lock_owner): Prefer signed type for sizes.
4245 Use memcpy, not strncpy, where memcpy is what is really wanted.
4246 Don't assume (via atoi) that time_t and pid_t fit in int.
4247 Check for time_t and/or pid_t out of range, e.g., via a network share.
4248 Don't alloca where an auto var works fine.
4249
4250 * fileio.c: Fix some integer overflow issues.
4251 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
4252 Don't assume string length fits in int.
4253 (directory_file_name): Don't assume string length fits in long.
4254 (make_temp_name): Don't assume pid fits in int, or that its print
4255 length is less than 20.
4256
4257 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
4258
4259 * coding.c (make_subsidiaries): Don't assume string length fits in int.
4260
4261 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
4262
4263 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
4264 We prefer signed integers, even for size calculations.
4265
4266 * emacs.c: Don't assume string length fits in 'int'.
4267 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
4268 (main): Don't invoke strlen when not needed.
4269
4270 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
4271 (XD_DEBUG_MESSAGE): Don't waste a byte.
4272
4273 * callproc.c (getenv_internal_1, getenv_internal)
4274 (Fgetenv_internal):
4275 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
4276
4277 * lread.c (invalid_syntax): Omit length argument.
4278 All uses changed. This doesn't fix a bug, but it simplifies the
4279 code away from its former Hollerith-constant appearance, and it's
4280 one less 'int' to worry about when looking at integer-overflow issues.
4281 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
4282
4283 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
4284 This didn't break anything, but it didn't help either.
4285 It's confusing to put a bogus integer in a place where the actual
4286 value does not matter.
4287 (LIST_END_P): Remove unused macro and its bogus comment.
4288 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
4289
4290 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
4291 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
4292 implementation.
4293 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
4294 We prefer signed types, and the value cannot exceed the EMACS_INT
4295 range anyway (because otherwise the length would not be representable).
4296 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
4297 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
4298 This avoids a GCC warning when WIDE_EMACS_INT.
4299
4300 * indent.c (sane_tab_width): New function.
4301 (current_column, scan_for_column, Findent_to, position_indentation)
4302 (compute_motion): Use it. This is just for clarity.
4303 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
4304
4305 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
4306
4307 * lisp.h (lint_assume): New macro.
4308 * composite.c (composition_gstring_put_cache):
4309 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
4310
4311 * editfns.c, insdel.c:
4312 Omit unnecessary forward decls, to simplify future changes.
4313
4314 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
4315
4316 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
4317
4318 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
4319 Use much-faster test for byte-length change.
4320 Don't assume string byte-length fits in 'int'.
4321 Check that character arg fits in 'int'.
4322 (mapcar1): Declare byte as byte, for clarity.
4323
4324 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
4325
4326 * fns.c (concat): Catch string overflow earlier.
4327 Do not rely on integer wraparound.
4328
4329 * dispextern.h (struct it.overlay_strings_charpos)
4330 (struct it.selective): Now EMACS_INT, not int.
4331 * xdisp.c (forward_to_next_line_start)
4332 (back_to_previous_visible_line_start)
4333 (reseat_at_next_visible_line_start, next_element_from_buffer):
4334 Don't arbitrarily truncate the value of 'selective' to int.
4335
4336 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
4337
4338 * composite.c: Don't truncate sizes to 'int'.
4339 (composition_gstring_p, composition_reseat_it)
4340 (composition_adjust_point): Use EMACS_INT, not int.
4341 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
4342 not EMACS_UINT, for indexes.
4343
4344 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
4345
4346 * buffer.c: Include <verify.h>.
4347 (struct sortvec.priority, struct sortstr.priority):
4348 Now EMACS_INT, not int.
4349 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
4350 (struct sortstr.size, record_overlay_string)
4351 (struct sortstrlist.size, struct sortlist.used):
4352 Don't truncate size to int.
4353 (record_overlay_string): Check for size-calculation overflow.
4354 (init_buffer_once): Check at compile-time, not run-time.
4355
4356 2011-06-22 Jim Meyering <meyering@redhat.com>
4357
4358 Don't leak an XBM-image-sized buffer
4359 * image.c (xbm_load): Free the image buffer after using it.
4360
4361 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
4362
4363 Port to Sun C.
4364 * composite.c (find_automatic_composition): Omit needless 'return 0;'
4365 that Sun C diagnosed.
4366 * fns.c (secure_hash): Fix pointer signedness issue.
4367 * intervals.c (static_offset_intervals): New function.
4368 (offset_intervals): Use it.
4369
4370 2011-06-21 Leo Liu <sdl.web@gmail.com>
4371
4372 * deps.mk (fns.o):
4373 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
4374 sha512.h.
4375
4376 * fns.c (secure_hash): Rename from crypto_hash_function and change
4377 the first arg to accept symbols.
4378 (Fsecure_hash): New primitive.
4379 (syms_of_fns): New symbols.
4380
4381 2011-06-20 Deniz Dogan <deniz@dogan.se>
4382
4383 * process.c (Fset_process_buffer): Clarify return value in
4384 docstring.
4385
4386 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
4387
4388 * dispnew.c (add_window_display_history): Use BVAR.
4389
4390 * xdisp.c (debug_method_add): Use BVAR.
4391 (check_window_end, dump_glyph_matrix, dump_glyph)
4392 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
4393
4394 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
4395 Likewise.
4396
4397 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
4398 check till after the cache is created in init_frame_faces.
4399
4400 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
4401
4402 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
4403
4404 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
4405
4406 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
4407 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
4408 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
4409
4410 Improve buffer-overflow checking (Bug#8873).
4411 * fileio.c (Finsert_file_contents):
4412 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
4413 Remove the old (too-loose) buffer overflow checks.
4414 They weren't needed, since make_gap checks for buffer overflow.
4415 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
4416 The old code merely checked for Emacs fixnum overflow, and relied
4417 on undefined (wraparound) behavior. The new code avoids undefined
4418 behavior, and also checks for ptrdiff_t and/or size_t overflow.
4419
4420 * editfns.c (Finsert_char): Don't dump core with very negative counts.
4421 Tune. Don't use wider integers than needed. Don't use alloca.
4422 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
4423
4424 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
4425
4426 * insdel.c, lisp.h (buffer_overflow): New function.
4427 (insert_from_buffer_1, replace_range, replace_range_2):
4428 * insdel.c (make_gap_larger):
4429 * editfns.c (Finsert_char):
4430 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
4431
4432 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
4433
4434 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
4435
4436 Integer overflow and signedness fixes (Bug#8873).
4437
4438 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
4439 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
4440
4441 * fileio.c: Don't assume EMACS_INT fits in off_t.
4442 (emacs_lseek): New static function.
4443 (Finsert_file_contents, Fwrite_region): Use it.
4444 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
4445
4446 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
4447
4448 * fns.c: Don't overflow int when computing a list length.
4449 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
4450 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
4451 truncation on 64-bit hosts. Check for QUIT every
4452 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
4453 faster and is responsive enough.
4454 (Flength): Report an error instead of overflowing an integer.
4455 (Fsafe_length): Return a float if the value is not representable
4456 as a fixnum. This shouldn't happen except in contrived situations.
4457 (Fnthcdr, Fsort): Don't assume list length fits in int.
4458 (Fcopy_sequence): Don't assume vector length fits in int.
4459
4460 * alloc.c: Check that resized vectors' lengths fit in fixnums.
4461 (header_size, word_size): New constants.
4462 (allocate_vectorlike): Don't check size overflow here.
4463 (allocate_vector): Check it here instead, since this is the only
4464 caller of allocate_vectorlike that could cause overflow.
4465 Check that the new vector's length is representable as a fixnum.
4466
4467 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
4468 The previous code was bogus. For example, next_almost_prime (32)
4469 returned 39, which is undesirable as it is a multiple of 3; and
4470 next_almost_prime (24) returned 25, which is a multiple of 5 so
4471 why was the code bothering to check for multiples of 7?
4472
4473 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
4474
4475 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
4476
4477 Variadic C functions now count arguments with ptrdiff_t.
4478 This partly undoes my 2011-03-30 change, which replaced int with size_t.
4479 Back then I didn't know that the Emacs coding style prefers signed int.
4480 Also, in the meantime I found a few more instances where arguments
4481 were being counted with int, which may truncate counts on 64-bit
4482 machines, or EMACS_INT, which may be unnecessarily wide.
4483 * lisp.h (struct Lisp_Subr.function.aMANY)
4484 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
4485 Arg counts are now ptrdiff_t, not size_t.
4486 All variadic functions and their callers changed accordingly.
4487 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
4488 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
4489 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
4490 * callint.c (Fcall_interactively): Check arg count for overflow,
4491 to avoid potential buffer overrun. Use signed char, not 'int',
4492 for 'varies' array, so that we needn't bother to check its size
4493 calculation for overflow.
4494 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
4495 * eval.c (apply_lambda):
4496 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
4497 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
4498 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
4499
4500 * callint.c (Fcall_interactively): Don't use index var as event count.
4501
4502 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
4503 * mem-limits.h (SIZE): Remove; no longer used.
4504
4505 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
4506
4507 Remove unnecessary casts.
4508 * xterm.c (x_term_init):
4509 * xfns.c (x_set_border_pixel):
4510 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
4511 These aren't needed now that we assume ANSI C.
4512
4513 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
4514 It's more likely to cause problems (due to unsigned overflow)
4515 than to cure them.
4516
4517 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
4518
4519 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
4520
4521 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
4522
4523 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
4524
4525 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
4526
4527 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
4528
4529 GLYPH_CODE_FACE returns EMACS_INT, not int.
4530 * dispextern.h (merge_faces):
4531 * xfaces.c (merge_faces):
4532 * xdisp.c (get_next_display_element, next_element_from_display_vector):
4533 Don't assume EMACS_INT fits in int.
4534
4535 * character.h (CHAR_VALID_P): Remove unused parameter.
4536 * fontset.c, lisp.h, xdisp.c: All uses changed.
4537
4538 * editfns.c (Ftranslate_region_internal): Omit redundant test.
4539
4540 * fns.c (concat): Minor tuning based on overflow analysis.
4541 This doesn't fix any bugs. Use int to hold character, instead
4542 of constantly refetching from Emacs object. Use XFASTINT, not
4543 XINT, for value known to be a character. Don't bother comparing
4544 a single byte to 0400, as it's always less.
4545
4546 * floatfns.c (Fexpt):
4547 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
4548
4549 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
4550 for characters.
4551
4552 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
4553
4554 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
4555 Without this fix, on a 64-bit host (aset S 0 4294967386) would
4556 incorrectly succeed when S was a string, because 4294967386 was
4557 truncated before it was used.
4558
4559 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
4560 Otherwise, an out-of-range integer could cause undefined behavior
4561 on a 64-bit host.
4562
4563 * composite.c: Use int, not EMACS_INT, for characters.
4564 (fill_gstring_body, composition_compute_stop_pos): Use int, not
4565 EMACS_INT, for values that are known to be in character range.
4566 This doesn't fix any bugs but is the usual style inside Emacs and
4567 may generate better code on 32-bit machines.
4568
4569 Make sure a 64-bit char is never passed to ENCODE_CHAR.
4570 This is for reasons similar to the recent CHAR_STRING fix.
4571 * charset.c (Fencode_char): Check that character arg is actually
4572 a character. Pass an int to ENCODE_CHAR.
4573 * charset.h (ENCODE_CHAR): Verify that the character argument is no
4574 wider than 'int', as a compile-time check to prevent future regressions
4575 in this area.
4576
4577 * character.c (char_string): Remove unnecessary casts.
4578
4579 Make sure a 64-bit char is never passed to CHAR_STRING.
4580 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
4581 by silently ignoring the top 32 bits, allowing some values
4582 that were far too large to be valid characters.
4583 * character.h: Include <verify.h>.
4584 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
4585 arguments are no wider than unsigned, as a compile-time check
4586 to prevent future regressions in this area.
4587 * data.c (Faset):
4588 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
4589 (Fsubst_char_in_region):
4590 * fns.c (concat):
4591 * xdisp.c (decode_mode_spec_coding):
4592 Adjust to CHAR_STRING's new requirement.
4593 * editfns.c (Finsert_char, Fsubst_char_in_region):
4594 * fns.c (concat): Check that character args are actually
4595 characters. Without this test, these functions did the wrong
4596 thing with wildly out-of-range values on 64-bit hosts.
4597
4598 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
4599 These casts should not be needed on 32-bit hosts, either.
4600 * keyboard.c (read_char):
4601 * lread.c (Fload): Remove casts to unsigned.
4602
4603 * lisp.h (UNSIGNED_CMP): New macro.
4604 This fixes comparison bugs on 64-bit hosts.
4605 (ASCII_CHAR_P): Use it.
4606 * casefiddle.c (casify_object):
4607 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
4608 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
4609 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
4610 * dispextern.h (FACE_FROM_ID):
4611 * keyboard.c (read_char): Use UNSIGNED_CMP.
4612
4613 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
4614 not to EMACS_INT, to avoid GCC warning.
4615
4616 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
4617
4618 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
4619 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
4620 isn't needed on 32-bit machines.

4672 size_t overflow on (unusual) hosts where SIZE_MAX <= min
4673 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
4674 and ptrdiff_t and EMACS_INT are both 64 bits.

5101 * fileio.c (Finsert_file_contents):
5102 Likewise for BUF_BYTES_MAX.
5103

5124 XINT -> XFASTINT, since the integer must be nonnegative.
5125 * ftfont.c (ftfont_spec_pattern):
5126 * keymap.c (access_keymap, silly_event_symbol_error):
5127 XUINT -> XFASTINT, since the integer must be nonnegative.
5128 (Fsingle_key_description, preferred_sequence_p): XUINT -> XINT,
5129 since it makes no difference and we prefer signed.
5130 * keyboard.c (record_char): Use XUINT when all the neighbors do.
5131 (access_keymap): NATNUMP -> INTEGERP, since the integer must be
5132 nonnegative.

5182 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
5183 Do not assume that spare memory exists; that assumption is valid
5184 only if SYSTEM_MALLOC.
5185 (LARGE_REQUEST): New macro, so that the issue of large requests
5186 is separated from the issue of spare memory.
5187
5188 2011-06-05 Andreas Schwab <schwab@linux-m68k.org>
5189

5243 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
5244 (bidi_level_of_next_char, bidi_move_to_visually_next):
5245 Support character positions inside a run of characters covered by a
5246 display string.
5247 (bidi_paragraph_init, bidi_resolve_explicit_1)
5248 (bidi_level_of_next_char): Call bidi_fetch_char and
5249 bidi_fetch_char_advance instead of FETCH_CHAR and
5250 FETCH_CHAR_ADVANCE.

5252 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
5253 definitions.
5254 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
5255 instead of using explicit *_CHAR codes.
5256 (bidi_resolve_explicit, bidi_resolve_weak):
5257 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
5258 bidirectional text is supported only in multibyte buffers.
5259 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
5260 it to initialize the frame_window_p member of struct bidi_it.

5267 were just reseat()'ed to a new position.
5268
5269 * xdisp.c (set_cursor_from_row): Set start and stop points
5270 according to the row's direction when priming the loop that looks
5271 for the glyph on which to display cursor.
5272 (single_display_spec_intangible_p): Function deleted.
5273 (display_prop_intangible_p): Reimplement to call
5274 handle_display_spec instead of single_display_spec_intangible_p.
5275 Accept 3 additional arguments needed by handle_display_spec.
5276 This fixes incorrect cursor motion across display property with complex
5277 values: lists, `(when COND...)' forms, etc.
5278 (single_display_spec_string_p): Support property values that are
5279 lists with the argument STRING its top-level element.
5280 (display_prop_string_p): Fix the condition for processing a
5281 property that is a list to be consistent with handle_display_spec.
5282 (handle_display_spec): New function, refactored from the
5283 last portion of handle_display_prop.
5284 (compute_display_string_pos): Accept additional argument
5285 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
5286 value of a `display' property is a "replacing spec".
5287 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
5288 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
5289 the display property, but just return a value indicating whether
5290 the display property will replace the characters it covers.
5291 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
5292 frame_window_p members of struct bidi_it.
5293 (compute_display_string_pos, compute_display_string_end):
5294 New functions.
5295 (push_it): Accept second argument POSITION, where pop_it should
5296 jump to continue iteration.

5300 display_prop_intangible_p to its new signature.
5301
5302 * dispextern.h (struct bidi_it): New member frame_window_p.
5303 (bidi_init_it): Update prototypes.
5304 (display_prop_intangible_p): Update prototype.
5305 (compute_display_string_pos, compute_display_string_end):

5316 All callers changed. (Bug#8762)
5317
5318 * gnutls.c: Use Emacs's memory allocators.
5319 Without this change, the gnutls library would invoke malloc etc.
5320 directly, which causes problems on non-SYNC_INPUT hosts, and which
5321 runs afoul of improving memory_full behavior. (Bug#8761)
5322 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
5323 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
5324 xfree instead of the default malloc, realloc, free.
5325 (Fgnutls_boot): No need to check for memory allocation failure,
5326 since xmalloc does that for us.
5327

5345 (xpm_put_color_table_h):
5346 * lisp.h (struct Lisp_Hash_Table):
5347 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
5348 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
5349 for hashes and hash indexes, instead of 'unsigned' and 'int'.
5350 * alloc.c (allocate_vectorlike):
5351 Check for overflow in vector size calculations.
5352 * ccl.c (ccl_driver):
5353 Check for overflow when converting EMACS_INT to int.
5354 * fns.c, image.c: Remove unnecessary static decls that would otherwise
5355 need to be updated by these changes.
5356 * fns.c (make_hash_table, maybe_resize_hash_table):
5357 Check for integer overflow with large hash tables.
5358 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
5359 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
5360 (SXHASH_REDUCE): New macro.
5361 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
5362 Use it instead of discarding useful hash info with large hash values.
5363 (sxhash_float): New function.
5364 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
5365 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
5366 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
5367 Rewrite to use FIXNUM_BITS, as this simplifies things.
5368 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
5369 Adjust signatures to match updated version of code.
5370 (consing_since_gc): Now EMACS_INT, since a single hash table can
5371 use more than INT_MAX bytes.
5372

5419
5420 Make it possible to run ./temacs.
5421
5422 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
5423 syms_of_callproc does the same thing. Remove test for
5424 "initialized", do it in the caller.

5446 * lisp.h (Qdebug): Remove decl. This reverts a part of the
5447 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
5448 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
5449
5450 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
5451
5452 * image.c: Various fixes to ImageMagick code comments.
5453 (Fimagemagick_types): Doc fix.
5454
5455 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
5456
5457 Minor fixes prompted by GCC 4.6.0 warnings.
5458
5459 * xselect.c (converted_selections, conversion_fail_tag): Now static.
5460
5461 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
5462 (x_clipboard_manager_save_all): Move extern decl to ...
5463 * xterm.h: ... here, so that it can be checked for consistency.
5464
5465 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
5466
5467 * xselect.c (x_clipboard_manager_save_frame)
5468 (x_clipboard_manager_save_all): New functions.
5469 (Fx_clipboard_manager_save): Lisp function deleted.
5470
5471 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
5472 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
5473
5474 * xterm.h: Update prototype.
5475
5476 2011-05-28 William Xu <william.xwl@gmail.com>
5477
5478 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
5479 exiting (Bug#8239).
5480
5481 2011-05-28 Jim Meyering <meyering@redhat.com>
5482
5483 Avoid a sign-extension bug in crypto_hash_function.
5484 * fns.c (to_uchar): Define.
5485 (crypto_hash_function): Use it to convert some newly-signed
5486 variables to unsigned, to avoid sign-extension bugs. For example,
5487 without this change, (md5 "truc") would evaluate to
5488 45723a2aff78ff4fff7fff1114760e62 rather than the expected
5489 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
5490 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
5491
5492 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
5493
5494 Integer overflow fixes.
5495
5496 * dbusbind.c: Serial number integer overflow fixes.
5497 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
5498 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
5499 to hold a serial number that is too large for a fixnum.
5500 (Fdbus_method_return_internal, Fdbus_method_error_internal):
5501 Check for serial numbers out of range. Decode any serial number
5502 that was so large that it became a float. (Bug#8722)
5503
5504 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
5505 (Fdbus_call_method, Fdbus_call_method_asynchronously):
5506 Use XFASTINT rather than XUINT when numbers are nonnegative.
5507 (xd_append_arg, Fdbus_method_return_internal):
5508 (Fdbus_method_error_internal): Likewise. Also, for unsigned
5509 arguments, check that Lisp number is nonnegative, rather than
5510 silently wrapping negative numbers around. (Bug#8722)
5511 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
5512 (Bug#8722)
5513
5514 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
5515
5516 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
5517
5518 ccl: add integer overflow checks
5519 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
5520 (IN_INT_RANGE): New macros.
5521 (ccl_driver): Use them to check for integer overflow when
5522 decoding a CCL program. Many of the new checks are whether XINT (x)
5523 fits in int; it doesn't always, on 64-bit hosts. The new version
5524 doesn't catch all possible integer overflows, but it's an
5525 improvement. (Bug#8719)
5526
5527 * alloc.c (make_event_array): Use XINT, not XUINT.
5528 There's no need for unsigned here.
5529
5530 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
5531 This follows up to the 2011-05-06 change that substituted uintptr_t
5532 for EMACS_INT. This case wasn't caught back then.
5533
5534 Rework Fformat to avoid integer overflow issues.
5535 * editfns.c: Include <float.h> unconditionally, as it's everywhere
5536 now (part of C89). Include <verify.h>.
5537 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
5538 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
5539 (Fformat): Avoid the prepass trying to compute sizes; it was only
5540 approximate and thus did not catch overflow reliably. Instead, walk
5541 through the format just once, formatting and computing sizes as we go,
5542 checking for integer overflow at every step, and allocating a larger
5543 buffer as needed. Keep track separately whether the format is
5544 multibyte. Keep only the most-recently calculated precision, rather
5545 than them all. Record whether each argument has been converted to
5546 string. Use EMACS_INT, not int, for byte and char and arg counts.
5547 Support field widths and precisions larger than INT_MAX. Avoid
5548 sprintf's undefined behavior with conversion specifications such as %#d
5549 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
5550 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
5551 formatting out-of-range floating point numbers with int
5552 formats. (Bug#8668)
5553
5554 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
5555
5556 * data.c: Avoid integer truncation in expressions involving floats.
5557 * data.c: Include <intprops.h>.
5558 (arith_driver): When there's an integer overflow in an expression
5559 involving floating point, convert the integers to floating point
5560 so that the resulting value does not suffer from catastrophic
5561 integer truncation. For example, on a 64-bit host (* 4
5562 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
5563 Do not rely on undefined behavior after integer overflow.
5564
5565 merge count_size_as_multibyte, parse_str_to_multibyte
5566 * character.c, character.h (count_size_as_multibyte):
5567 Rename from parse_str_to_multibyte; all uses changed.
5568 Check for integer overflow.
5569 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
5570 since it's now a duplicate of the other. This is more of
5571 a character than a buffer op, so better that it's in character.c.
5572 * fns.c, print.c: Adjust to above changes.
5573
5574 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
5575
5576 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
5577
5578 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
5579
5580 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
5581 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
5582 (x_clipboard_manager_save): Now static.
5583 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
5584
5585 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
5586 (crypto_hash_function): Now static.
5587 Fix pointer signedness problems. Avoid unnecessary initializations.
5588
5589 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
5590
5591 * termhooks.h (Vselection_alist): Make it terminal-local.
5592
5593 * terminal.c (create_terminal): Initialize it.
5594
5595 * xselect.c: Support for clipboard managers.
5596 (Vselection_alist): Move to termhooks.h as terminal-local var.
5597 (LOCAL_SELECTION): New macro.
5598 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
5599 (symbol_to_x_atom): Remove gratuitous arg.
5600 (x_handle_selection_request, lisp_data_to_selection_data)
5601 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
5602 (x_own_selection, x_get_local_selection, x_convert_selection):
5603 New arg, specifying work frame. Use terminal-local Vselection_alist.
5604 (some_frame_on_display): Delete unused function.
5605 (Fx_own_selection_internal, Fx_get_selection_internal)
5606 (Fx_disown_selection_internal, Fx_selection_owner_p)
5607 (Fx_selection_exists_p): New optional frame arg.
5608 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
5609 (x_handle_selection_clear): Don't treat other terminals with the
5610 same keyboard specially. Use the terminal-local Vselection_alist.
5611 (x_clear_frame_selections): Use Frun_hook_with_args.
5612
5613 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
5614
5615 * xterm.h: Add support for those atoms.
5616
5617 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
5618
5619 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
5620 (converted_selections, conversion_fail_tag): New global variables.
5621 (x_selection_request_lisp_error): Free the above.
5622 (x_get_local_selection): Remove unnecessary code.
5623 (x_reply_selection_request): Args changed; handle arbitrary array
5624 of converted selections stored in converted_selections.
5625 Separate the XChangeProperty and SelectionNotify steps.
5626 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
5627 (x_convert_selection): New function.
5628 (x_handle_selection_event): Simplify.
5629 (x_get_foreign_selection): Don't ignore incoming requests while
5630 waiting for an answer; this will fail when we implement
5631 SAVE_TARGETS, and seems unnecessary anyway.
5632 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
5633 (Vx_sent_selection_functions): Doc fix.
5634
5635 2011-05-26 Leo Liu <sdl.web@gmail.com>
5636
5637 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
5638
5639 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5640
5641 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
5642
5643 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
5644 for fringe update if it has periodic bitmap.
5645 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
5646 and fringe_bitmap_periodic_p.
5647
5648 * fringe.c (get_fringe_bitmap_data): New function.
5649 (draw_fringe_bitmap_1, update_window_fringes): Use it.
5650 (update_window_fringes): Record periodicity of fringe bitmap in glyph
5651 row. Mark glyph row for fringe update if periodicity changed.
5652
5653 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
5654 for fringe update unless it has periodic bitmap.
5655
5656 2011-05-25 Kenichi Handa <handa@m17n.org>
5657
5658 * xdisp.c (get_next_display_element): Set correct it->face_id for
5659 a static composition.
5660
5661 2011-05-24 Leo Liu <sdl.web@gmail.com>
5662
5663 * deps.mk (fns.o):
5664 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
5665
5666 * fns.c (crypto_hash_function, Fsha1): New function.
5667 (Fmd5): Use crypto_hash_function.
5668 (syms_of_fns): Add Ssha1.
5669
5670 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
5671
5672 * gnutls.c: Remove unused macros.
5673 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
5674 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
5675 Remove macros that are defined and never used.
5676 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
5677
5678 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
5679
5680 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
5681 (Fx_get_selection_internal): Minor cleanup.
5682 (Fx_own_selection_internal): Rename arguments for consistency with
5683 select.el.
5684
5685 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
5686
5687 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
5688
5689 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
5690
5691 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
5692
5693 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5694
5695 * dispnew.c (scrolling_window): Don't exclude the case that the
5696 last enabled row in the desired matrix touches the bottom boundary.
5697
5698 2011-05-21 Glenn Morris <rgm@gnu.org>
5699
5700 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
5701 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
5702 and add some more files.
5703
5704 2011-05-20 Eli Zaretskii <eliz@gnu.org>
5705
5706 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
5707 report_file_error introduced by the change from 2011-05-07.
5708
5709 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
5710
5711 * systime.h (Time): Define only if emacs is defined.
5712 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
5713 where the include path doesn't have X11/X.h by default. See
5714 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
5715
5716 2011-05-20 Kenichi Handa <handa@m17n.org>
5717
5718 * composite.c (find_automatic_composition): Fix previous change.
5719
5720 2011-05-20 Glenn Morris <rgm@gnu.org>
5721
5722 * lisp.mk: New file, split from Makefile.in.
5723 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
5724 (shortlisp): Remove.
5725 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
5726
5727 2011-05-19 Glenn Morris <rgm@gnu.org>
5728
5729 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
5730 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
5731 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
5732 (lisp): Set the order to that of loadup.el.
5733 (shortlisp): Make it a copy of $lisp.
5734 (SOME_MACHINE_LISP): Remove.
5735 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
5736 Use just $shortlisp, not $SOME_MACHINE_LISP too.
5737
5738 2011-05-18 Kenichi Handa <handa@m17n.org>
5739
5740 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
5741 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
5742 (find_automatic_composition): Mostly rewrite for efficiency.
5743
5744 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
5745
5746 * makefile.w32-in: Update dependencies.
5747
5748 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
5749
5750 * menu.c: Include limits.h (fixes the MS-Windows build broken by
5751 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
5752
5753 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
5754
5755 Fix some integer overflow issues, such as string length overflow.
5756
5757 * insdel.c (count_size_as_multibyte): Check for string overflow.
5758
5759 * character.c (lisp_string_width): Check for string overflow.
5760 Use EMACS_INT, not int, for string indexes and lengths; in
5761 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
5762 the resulting string length overflows an EMACS_INT; instead,
5763 report a string overflow if no precision given. When checking for
5764 precision exhaustion, use a check that cannot possibly have
5765 integer overflow. (Bug#8675)
5766 * character.h (lisp_string_width): Adjust to new signature.
5767
5768 * alloc.c (string_overflow): New function.
5769 (Fmake_string): Use it. This doesn't change behavior, but saves
5770 a few bytes and will simplify future changes.
5771 * character.c (string_escape_byte8): Likewise.
5772 * lisp.h (string_overflow): New decl.
5773
5774 Fixups, following up to the user-interface timestamp change.
5775 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
5776 for UI timestamps, instead of unsigned long.
5777 * msdos.c (mouse_get_pos): Likewise.
5778 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
5779 * w32gui.h (Time): Define by including "systime.h" rather than by
5780 declaring it ourselves. (Bug#8664)
5781
5782 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
5783 * image.c (clear_image_cache): Likewise.
5784
5785 * term.c (term_mouse_position): Don't assume time_t wraparound.
5786
5787 Be more systematic about user-interface timestamps.
5788 Before, the code sometimes used 'Time', sometimes 'unsigned long',
5789 and sometimes 'EMACS_UINT', to represent these timestamps.
5790 This change causes it to use 'Time' uniformly, as that's what X uses.
5791 This makes the code easier to follow, and makes it easier to catch
5792 integer overflow bugs such as Bug#8664.
5793 * frame.c (Fmouse_position, Fmouse_pixel_position):
5794 Use Time, not unsigned long, for user-interface timestamps.
5795 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
5796 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
5797 * keyboard.h (last_event_timestamp): Likewise.
5798 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
5799 * menu.h (xmenu_show): Likewise.
5800 * term.c (term_mouse_position): Likewise.
5801 * termhooks.h (struct input_event.timestamp): Likewise.
5802 (struct terminal.mouse_position_hook): Likewise.
5803 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
5804 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
5805 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
5806 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
5807 what it was before.
5808 * menu.h, termhooks.h: Include "systime.h", for Time.
5809
5810 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
5811 Don't assume that the difference between two unsigned long values
5812 can fit into an integer. At this point, we know button_down_time
5813 <= event->timestamp, so the difference must be nonnegative, so
5814 there's no need to cast the result if double-click-time is
5815 nonnegative, as it should be; check that it's nonnegative, just in
5816 case. This bug is triggered when events are more than 2**31 ms
5817 apart (about 25 days). (Bug#8664)
5818
5819 * xselect.c (last_event_timestamp): Remove duplicate decl.
5820 (x_own_selection): Remove needless cast to unsigned long.
5821
5822 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
5823 that always fit in int. Use a sentinel instead of a counter, to
5824 avoid a temp and to allay GCC's concerns about possible int overflow.
5825 * frame.h (struct frame): Use int for menu_bar_items_used
5826 instead of EMACS_INT, since it always fits in int.
5827
5828 * menu.c (grow_menu_items): Check for int overflow.
5829
5830 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
5831
5832 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
5833 Before, the code was not consistent. These values cannot exceed
5834 2**31 - 1 so there's no need to make them unsigned.
5835 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
5836 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
5837 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
5838 as modifiers.
5839 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
5840
5841 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
5842 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
5843 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
5844 presumably because the widths might not match.
5845
5846 * window.c (size_window): Avoid needless test at loop start.
5847
5848 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
5849
5850 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
5851
5852 2011-05-12 Drew Adams <drew.adams@oracle.com>
5853
5854 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
5855
5856 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5857
5858 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
5859 `width' to `bar_area_x' and `bar_area_width', respectively.
5860 (x_scroll_run): Take account of fringe background extension.
5861
5862 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
5863 Rename local vars `left' and `width' to `bar_area_x' and
5864 `bar_area_width', respectively.
5865 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
5866 background extension.
5867
5868 2011-05-10 Jim Meyering <meyering@redhat.com>
5869
5870 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
5871
5872 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
5873
5874 * image.c (Finit_image_library): Return t for built-in image types,
5875 like pbm and xbm. (Bug#8640)
5876
5877 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
5878
5879 * w32menu.c (set_frame_menubar): Fix submenu allocation.
5880
5881 2011-05-07 Eli Zaretskii <eliz@gnu.org>
5882
5883 * w32console.c (Fset_screen_color): Doc fix.
5884 (Fget_screen_color): New function.
5885 (syms_of_ntterm): Defsubr it.
5886
5887 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
5888 unlink the temporary file if Fcall_process didn't create it in the
5889 first place.
5890 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
5891 child process will be redirected to a file specified with `:file'.
5892 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
5893 cue to call_process_cleanup not to close that handle.
5894
5895 2011-05-07 Ben Key <bkey76@gmail.com>
5896
5897 * makefile.w32-in: The bootstrap-temacs rule now makes use of
5898 one of two shell specific rules, either bootstrap-temacs-CMD or
5899 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
5900 to the previous implementation of the bootstrap-temacs rule.
5901 The bootstrap-temacs-CMD rule is similar to the previous
5902 implementation of the bootstrap-temacs rule except that it
5903 makes use of the ESC_CFLAGS variable instead of the CFLAGS
5904 variable.
5905
5906 These changes, along with some changes to nt/configure.bat,
5907 nt/gmake.defs, and nt/nmake.defs, are required to extend my
5908 earlier fix to add support for --cflags and --ldflags options
5909 that include quotes so that it works whether make uses cmd or
5910 sh as the shell.
5911
5912 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
5913
5914 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
5915 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
5916 is a constant.
5917 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
5918 a string. Handle both cases.
5919 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
5920 (Fdbus_register_method): Use Qinvalid_function.
5921
5922 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
5923
5924 * makefile.w32-in: Update dependencies.
5925 (LISP_H): Add inttypes.h and stdin.h.
5926 (PROCESS_H): Add unistd.h.
5927
5928 2011-05-06 Eli Zaretskii <eliz@gnu.org>
5929
5930 * lread.c: Include limits.h (fixes the MS-Windows build broken by
5931 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
5932
5933 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
5934
5935 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
5936
5937 * term.c (vfatal): Remove stray call to va_end.
5938 It's not needed and the C Standard doesn't allow it here anyway.
5939
5940 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
5941 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
5942
5943 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
5944 bytes.
5945
5946 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
5947
5948 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
5949
5950 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
5951
5952 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
5953
5954 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
5955
5956 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
5957 * charset.c (Fdefine_charset_internal): Don't initialize
5958 charset.code_space[15]. The value was garbage, on hosts with
5959 32-bit int (Bug#8600).
5960
5961 * lread.c (read_integer): Be more consistent with string-to-number.
5962 Use string_to_number to do the actual conversion; this avoids
5963 rounding errors and fixes some other screwups. Without this fix,
5964 for example, #x1fffffffffffffff was misread as -2305843009213693952.
5965 (digit_to_number): Move earlier, for benefit of read_integer.
5966 Return -1 if the digit is out of range for the base, -2 if it is
5967 not a digit in any supported base. (Bug#8602)
5968
5969 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
5970
5971 * dispnew.c (scrolling_window): Return 1 if we scrolled,
5972 to match comment at start of function. This also removes a
5973 GCC warning about overflow in a 32+64-bit port.
5974
5975 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
5976
5977 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
5978 Reported by Stefan Monnier in
5979 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
5980 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
5981 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
5982
5983 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
5984 (EMACS_UINTPTR): Likewise, with uintptr_t.
5985
5986 * lisp.h: Prefer 64-bit EMACS_INT if available.
5987 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
5988 on 32-bit hosts that have 64-bit int, so that they can access
5989 large files.
5990 However, temporarily disable this change unless the temporary
5991 symbol WIDE_EMACS_INT is defined.
5992
5993 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
5994
5995 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
5996 This removes an assumption that EMACS_INT and long are the same
5997 width as pointers. The assumption is true for Emacs porting targets
5998 now, but we want to make other targets possible.
5999 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
6000 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
6001 In the rest of the code, change types of integers that hold casted
6002 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
6003 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
6004 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
6005 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
6006 No need to cast type when ORing.
6007 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
6008 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
6009 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
6010 assume EMACS_INT is the same width as char *.
6011 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
6012 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
6013 Remove no-longer-needed casts.
6014 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
6015 (xg_tool_bar_help_callback, xg_make_tool_item):
6016 Use EMACS_INTPTR to hold an integer
6017 that will be cast to void *; this can avoid a GCC warning
6018 if EMACS_INT is not the same width as void *.
6019 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
6020 * xdisp.c (display_echo_area_1, resize_mini_window_1):
6021 (current_message_1, set_message_1):
6022 Use a local to convert to proper width without a cast.
6023 * xmenu.c (dialog_selection_callback): Likewise.
6024
6025 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
6026 Also, don't assume VALBITS / RAND_BITS is less than 5,
6027 and don't rely on undefined behavior when shifting a 1 left into
6028 the sign bit.
6029 * lisp.h (get_random): Change signature to match.
6030
6031 * lread.c (hash_string): Use size_t, not int, for hash computation.
6032 Normally we prefer signed values; but hashing is special, because
6033 it's better to use unsigned division on hash table sizes so that
6034 the remainder is nonnegative. Also, size_t is the natural width
6035 for hashing into memory. The previous code used 'int', which doesn't
6036 retain enough info to hash well into very large tables.
6037 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
6038
6039 * dbusbind.c: Don't possibly lose pointer info when converting.
6040 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
6041 Use XPNTR rather than XHASH, so that the high-order bits of
6042 the pointer aren't lost when converting through void *.
6043
6044 * eval.c (Fautoload): Don't double-shift a pointer.
6045
6046 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
6047
6048 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
6049
6050 * gnutls.c (DEF_GNUTLS_FN):
6051 * image.c (DEF_IMGLIB_FN): Make function pointers static.
6052
6053 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
6054
6055 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
6056 marker. (Bug#8610)
6057
6058 2011-05-05 Eli Zaretskii <eliz@gnu.org>
6059

6080 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
6081 Remove unused parameter `fildes'.
6082 * process.c (read_process_output, send_process): Don't pass it.
6083
6084 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
6085
6086 Fix previous change: the library cache is defined in w32.c.
6087 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
6088 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
6089
6090 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
6091
6092 Implement dynamic loading of GnuTLS on Windows.

6100 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
6101 (gnutls_*): Declare function pointers.
6102 (init_gnutls_functions): New function to initialize function pointers.
6103 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
6104 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
6105 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
6106 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
6107 (emacs_gnutls_write, emacs_gnutls_read)
6108 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
6109 (Fgnutls_available_p): New function.
6110 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.

6123 (w32_delayed_load): Move from image.c. When loading a library, record
6124 its filename in the :loaded-from property of the library id.
6125 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
6126 Initialize and staticpro them.
6127 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
6128
6129 * process.c: Include lisp.h before w32.h, not after.
6130 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
6131 instead of gnutls_record_check_pending.

6159 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
6160 (Qgnutls_bootprop_callbacks_verify): Make static.
6161
6162 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
6163
6164 * callproc.c: Indentation fixup.
6165
6166 * sysdep.c (wait_for_termination_1): Make static.
6167 (wait_for_termination, interruptible_wait_for_termination):
6168 Move after wait_for_termination_1.
6169
6170 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
6171
6172 * sysdep.c (interruptible_wait_for_termination): New function
6173 which is like wait_for_termination, but allows keyboard
6174 interruptions.
6175
6176 * callproc.c (Fcall_process): Add (:file "file") as an option for
6177 the STDOUT buffer.
6178 (Fcall_process_region): Ditto.
6179

6196 will grow beyond MOST_POSITIVE_FIXNUM.
6197 (decode_coding_emacs_mule): Abort if there isn't enough place in
6198 charbuf for the composition carryover bytes. Reserve an extra
6199 space for up to 2 characters produced in a loop.
6200 (decode_coding_iso_2022): Abort if there isn't enough place in
6201 charbuf for the composition carryover bytes.
6202
6203 2011-04-21 Eli Zaretskii <eliz@gnu.org>
6204
6205 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
6206 aborting when %lld or %lll format is passed.
6207 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when

6239
6240 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
6241 (Fx_window_property): #if-0 the whole functions, not just the bodies.
6242
6243 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
6244
6245 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
6246

6248
6249 * makefile.w32-in: Update dependencies.
6250
6251 2011-04-27 Eli Zaretskii <eliz@gnu.org>

6253 Improve `doprnt' and its usage. (Bug#8545)
6254 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
6255 `format_end'. Remove support for %l as a conversion specifier.
6256 Don't use xrealloc. Improve diagnostics when the %l size modifier
6257 is used. Update the commentary.
6258
6259 * eval.c (verror): Simplify calculation of size_t.
6260
6261 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
6262 messages.
6263
6264 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
6265
6266 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
6267 change.
6268
6269 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
6270
6271 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
6272 This makes this file independent of the recent pseudovector change.
6273
6274 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
6275
6276 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
6277
6278 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
6279 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
6280 Remove unused local.
6281 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
6282
6283 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
6284 GCC 4.6.0 optimizes based on type-based alias analysis.
6285 For example, if b is of type struct buffer * and v of type struct
6286 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
6287 != &v->size, and therefore "v->size = 1; b->size = 2; return
6288 v->size;" must therefore return 1. This assumption is incorrect
6289 for Emacs, since it type-puns struct Lisp_Vector * with many other
6290 types. To fix this problem, this patch adds a new type struct
6291 vectorlike_header that documents the constraints on layout of vectors
6292 and pseudovectors, and helps optimizing compilers not get fooled
6293 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
6294 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
6295 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
6296 the size member.
6297 (XSETPVECTYPE): Rewrite in terms of new macro.
6298 (XSETPVECTYPESIZE): New macro, specifying both type and size.
6299 This is a bit clearer, and further avoids the possibility of
6300 undesirable aliasing.
6301 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
6302 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
6303 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
6304 since Lisp_Subr is a special case (no "next" field).
6305 (ASIZE): Now uses header.size rather than size.
6306 All previous uses of XVECTOR (foo)->size replaced to use this macro,
6307 to avoid the hassle of writing XVECTOR (foo)->header.size.
6308 (struct vectorlike_header): New type.
6309 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
6310 object, to help avoid aliasing.
6311 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
6312 (SUBRP): Likewise, since Lisp_Subr is a special case.
6313 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
6314 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
6315 (struct Lisp_Hash_Table): Combine first two members into a single
6316 struct vectorlike_header member. All uses of "size" and "next" members
6317 changed to be "header.size" and "header.next".
6318 * buffer.h (struct buffer): Likewise.
6319 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
6320 * frame.h (struct frame): Likewise.
6321 * process.h (struct Lisp_Process): Likewise.
6322 * termhooks.h (struct terminal): Likewise.
6323 * window.c (struct save_window_data, struct saved_window): Likewise.
6324 * window.h (struct window): Likewise.
6325 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
6326 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
6327 * buffer.c (init_buffer_once): Likewise.
6328 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
6329 special case.
6330 * process.c (Fformat_network_address): Use local var for size,
6331 for brevity.
6332
6333 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
6334
6335 Make the Lisp reader and string-to-float more consistent (Bug#8525)
6336 * data.c (atof): Remove decl; no longer used or needed.
6337 (digit_to_number): Move to lread.c.
6338 (Fstring_to_number): Use new string_to_number function, to be
6339 consistent with how the Lisp reader treats infinities and NaNs.
6340 Do not assume that floating-point numbers represent EMACS_INT
6341 without losing information; this is not true on most 64-bit hosts.
6342 Avoid double-rounding errors, by insisting on integers when
6343 parsing non-base-10 numbers, as the documentation specifies.
6344 * lisp.h (string_to_number): New decl, replacing ...
6345 (isfloat_string): Remove.
6346 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
6347 (read1): Do not accept +. and -. as integers; this
6348 appears to have been a coding error. Similarly, do not accept
6349 strings like +-1e0 as floating point numbers. Do not report
6350 overflow for integer overflows unless the base is not 10 which
6351 means we have no simple and reliable way to continue.
6352 Break out the floating-point parsing into a new
6353 function string_to_number, so that Fstring_to_number parses
6354 floating point numbers consistently with the Lisp reader.
6355 (digit_to_number): Move here from data.c. Make it static inline.
6356 (E_CHAR, EXP_INT): Remove, replacing with ...
6357 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
6358 (string_to_number): New function, replacing isfloat_string.
6359 This function checks for valid syntax and produces the resulting
6360 Lisp float number too. Rework it so that string-to-number
6361 no longer mishandles examples like "1.0e+". Use strtoumax,
6362 so that overflow for non-base-10 numbers is reported only when
6363 there's no portable and simple way to convert to floating point.
6364
6365 * textprop.c (set_text_properties_1): Rewrite for clarity,
6366 and to avoid GCC warning about integer overflow.
6367
6368 * intervals.h (struct interval): Use EMACS_INT for members
6369 where EMACS_UINT might cause problems. See
6370 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
6371 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
6372 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
6373 All uses changed.
6374 (offset_intervals): Tell GCC not to worry about length overflow
6375 when negating a negative length.
6376
6377 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
6378 (overrun_check_free): Likewise.
6379
6380 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
6381 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
6382 word size.
6383
6384 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
6385 (gnutls_make_error): Rename local to avoid shadowing.
6386 (gnutls_emacs_global_deinit): ifdef out; not used.
6387 (Fgnutls_boot): Use const for pointer to readonly storage.
6388 Comment out unused local. Fix pointer signedness problems.
6389
6390 * lread.c (openp): Don't stuff size_t into an 'int'.
6391 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
6392 about possible signed overflow.
6393
6394 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
6395 (GDK_KEY_g): Don't define if already defined.
6396 (xg_prepare_tooltip): Avoid pointer signedness problem.
6397 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
6398
6399 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
6400 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
6401
6402 * xfns.c (Fx_window_property): Simplify a bit,
6403 to make a bit faster and to avoid GCC 4.6.0 warning.
6404 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
6405
6406 * fns.c (internal_equal): Don't assume size_t fits in int.
6407
6408 * alloc.c (compact_small_strings): Tighten assertion a little.
6409
6410 Replace pEd with more-general pI, and fix some printf arg casts.
6411 * lisp.h (pI): New macro, generalizing old pEd macro to other
6412 conversion specifiers. For example, use "...%"pI"d..." rather
6413 than "...%"pEd"...".
6414 (pEd): Remove. All uses replaced with similar uses of pI.
6415 * src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h: Likewise.
6416 * alloc.c (check_pure_size): Don't overflow by converting size to int.
6417 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
6418 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
6419 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
6420 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
6421 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
6422 64-bit hosts.
6423 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
6424 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
6425 * print.c (safe_debug_print, print_object): Likewise.
6426 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
6427 to int.
6428 Use pI instead of if-then-else-abort. Use %p to avoid casts,
6429 avoiding the 0 flag, which is not portable.
6430 * process.c (Fmake_network_process): Use pI to avoid cast.
6431 * region-cache.c (pp_cache): Likewise.
6432 * xdisp.c (decode_mode_spec): Likewise.
6433 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
6434 behavior on 64-bit hosts with printf arg.
6435 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
6436 (x_stop_queuing_selection_requests): Likewise.
6437 (x_get_window_property): Don't truncate byte count to an 'int'
6438 when tracing.
6439
6440 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
6441 here, since it parses constructs like leading '-' and spaces,
6442 which are not wanted; and it overflows with large numbers.
6443 Instead, simply match F[0-9]+, which is what is wanted anyway.
6444
6445 * alloc.c: Remove unportable assumptions about struct layout.
6446 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
6447 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
6448 (allocate_vectorlike, make_pure_vector): Use the new macros,
6449 plus offsetof, to remove unportable assumptions about struct layout.
6450 These assumptions hold on all porting targets that I know of, but
6451 they are not guaranteed, they're easy to remove, and removing them
6452 makes further changes easier.
6453
6454 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
6455 This doesn't fix a bug but makes the code clearer.
6456 (string_overrun_cookie): Now const. Use initializers that
6457 don't formally overflow signed char, to avoid warnings.
6458 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
6459 can cause Emacs to crash when string overrun checking is enabled.
6460 (allocate_buffer): Don't assume sizeof (struct buffer) is a
6461 multiple of sizeof (EMACS_INT); it need not be, if
6462 alignof(EMACS_INT) < sizeof (EMACS_INT).
6463 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
6464
6465 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
6466
6467 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
6468

6470
6471 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
6472 supposed to be handshaking. (Bug#8556)
6473 Reported by Paul Eggert <eggert@cs.ucla.edu>.
6474
6475 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
6476
6477 * lisp.h (Qdebug): List symbol.
6478 * eval.c (Qdebug): Restore global linkage.
6479 * keyboard.c (debug-on-event): New variable.
6480 (handle_user_signal): Break into debugger when debug-on-event
6481 matches the current signal symbol.
6482
6483 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
6484
6485 * alloc.c (check_sblock, check_string_bytes)
6486 (check_string_free_list): Convert to standard C.
6487
6488 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
6489
6490 * w32.c (emacs_gnutls_push): Fix typo.
6491
6492 2011-04-25 Eli Zaretskii <eliz@gnu.org>
6493
6494 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
6495 "cast to pointer from integer of different size".
6496
6497 Improve doprnt and its use in verror. (Bug#8545)
6498 * doprnt.c (doprnt): Document the set of format control sequences
6499 supported by the function. Use SAFE_ALLOCA instead of always
6500 using `alloca'.
6501
6502 * eval.c (verror): Don't limit the buffer size at size_max-1, that
6503 is one byte too soon. Don't use xrealloc; instead xfree and
6504 xmalloc anew.
6505
6506 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
6507
6508 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
6509 callbacks stage.
6510
6511 * gnutls.c: Renamed global_initialized to
6512 gnutls_global_initialized. Added internals for the
6513 :verify-hostname-error, :verify-error, and :verify-flags
6514 parameters of `gnutls-boot' and documented those parameters in the
6515 docstring. Start callback support.
6516 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
6517 unless a fatal error occurred. Call gnutls_alert_send_appropriate
6518 on error. Return error code.
6519 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
6520 (emacs_gnutls_read): Likewise.
6521 (Fgnutls_boot): Return handshake error code.
6522 (emacs_gnutls_handle_error): New function.

6530
6531 2011-04-24 Claudio Bley <claudio.bley@gmail.com> (tiny change)
6532
6533 * process.c (wait_reading_process_output): Check if GnuTLS
6534 buffered some data internally if no FDs are set for TLS
6535 connections.
6536
6537 * makefile.w32-in (OBJ2): Add gnutls.$(O).

6542
6543 * xdisp.c (handle_single_display_spec): Rename the
6544 display_replaced_before_p argument into display_replaced_p, to
6545 make it consistent with the commentary. Fix typos in the
6546 commentary.
6547
6548 * textprop.c (syms_of_textprop): Remove dead code.
6549 (copy_text_properties): Delete obsolete commentary about an
6550 interface that was deleted long ago. Fix typos in the description
6551 of arguments.

6554 to changes in oldXMenu/XMenu.h from 2011-04-16.
6555 <menu_help_message, prev_menu_help_message>: Constify.
6556 (IT_menu_make_room): menu->help_text is now `const char **';
6557 adjust.
6558
6559 * msdos.h (XMenuActivate, XMenuAddSelection): Adjust prototypes
6560 to changes in oldXMenu/XMenu.h from 2011-04-16.

6563 * xfaces.c <Qunspecified>: Make extern again.
6564
6565 * syntax.c: Include sys/types.h before including regex.h, as
6566 required by Posix.

6569
6570 * doprnt.c (doprnt): Improve commentary.
6571
6572 * term.c (init_tty) [MSDOS]: Fix 1st argument to maybe_fatal.
6573
6574 * Makefile.in (TAGS): Depend on $(M_FILE) and $(S_FILE), and scan
6575 them with etags.
6576
6577 * makefile.w32-in (globals.h): Add a dummy recipe, to make any
6578 changes in globals.h immediately force recompilation.
6579 (TAGS): Depend on $(CURDIR)/m/intel386.h and
6580 $(CURDIR)/s/ms-w32.h.
6581 (TAGS-gmake): Scan $(CURDIR)/m/intel386.h and $(CURDIR)/s/ms-w32.h.
6582
6583 * character.c (Fchar_direction): Function deleted.
6584 (syms_of_character): Don't defsubr it.
6585 <char-direction-table>: Deleted.
6586
6587 2011-04-23 Eli Zaretskii <eliz@gnu.org>
6588
6589 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
6590 * doprnt.c: Include limits.h.
6591 (SIZE_MAX): New macro.
6592 (doprnt): Return a size_t value. 2nd arg is now size_t.
6593 Many local variables are now size_t instead of int or unsigned.
6594 Improve overflow protection. Support `l' modifier for integer
6595 conversions. Support %l conversion. Don't assume an EMACS_INT
6596 argument for integer conversions and for %c.
6597
6598 * lisp.h (doprnt): Restore prototype.
6599
6600 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
6601 $(SRC)/character.h.
6602
6603 * Makefile.in (base_obj): Add back doprnt.o.
6604
6605 * deps.mk (doprnt.o): Add back prerequisites.
6606 (callint.o): Depend on character.h.
6607
6608 * eval.c (internal_lisp_condition_case): Include the handler
6609 representation in the error message.
6610 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
6611 when breaking from the loop.
6612
6613 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
6614
6615 * callint.c (Fcall_interactively): When displaying error message
6616 about invalid control letter, pass the character's codepoint, not
6617 a pointer to its multibyte form. Improve display of the character
6618 in octal and display also its hex code.
6619
6620 * character.c (char_string): Use %x to display the (unsigned)
6621 codepoint of an invalid character, to avoid displaying a bogus
6622 negative value.
6623
6624 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
6625 `error', not SYMBOL_NAME itself.
6626
6627 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
6628 character arguments to `error'.
6629
6630 * charset.c (check_iso_charset_parameter): Fix incorrect argument
6631 to `error' in error message about FINAL_CHAR argument. Make sure
6632 FINAL_CHAR is a character, and use %c when it is passed as
6633 argument to `error'.
6634

6821
6822 * nsfont.m: Fixed bugs in ns_get_family and
6823 ns_descriptor_to_entity that were caused by using free to
6824 deallocate memory blocks that were allocated by xmalloc (via
6825 xstrdup). This caused Emacs to crash when compiled with
6826 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
6827 --enable-checking=xmallocoverrun). xfree is now used to
6828 deallocate these memory blocks.

6845 (emacs_read, emacs_write): Use it.

7181 * bidi.c (bidi_dump_cached_states): Mark as externally visible,
7182 so that it's not optimized away.
7183 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
7184 * dispextern.h (bidi_dump_cached_states): Remove, since it's
7185 exported only to the debugger.
7186
7187 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
7188 * atimer.h (run_all_atimers): Remove; not exported.
7189
7190 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
7191 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
7192 was inaccessible from Lisp.

7195
7196 alloc.c: Import and export fewer symbols, and remove unused items.
7197 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
7198 is defined.
7199 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
7200 it's not optimized away by whole-program optimization.
7201 (message_enable_multibyte, free_misc): Remove.
7202 (catchlist, handlerlist, mark_backtrace):

7214 * xdisp.c (message_enable_multibyte): Now static.
7215
7216 Declare Lisp_Object Q* variables to be 'static' if not exported.
7217 This makes it easier for human readers (and static analyzers)
7218 to see whether these variables are used from other modules.
7219 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
7220 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:

7230 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
7231
7232 * lisp.h (DEFINE_FUNC): Make sname 'static'.
7233
7234 Make Emacs functions such as Fatom 'static' by default.
7235 This makes it easier for human readers (and static analyzers)
7236 to see whether these functions can be called from other modules.
7237 DEFUN now defines a static function. To make the function external
7238 so that it can be used in other C modules, use the new macro DEFUE.
7239 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
7240 (Finit_image_library):
7241 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
7242 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
7243 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
7244 Remove decls, since these functions are now static.
7245 (Funintern, Fget_internal_run_time): New decls, since these functions
7246 were already external.
7247

7255 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
7256 Mark functions with DEFUE instead of DEFUN,
7257 if they are used in other modules.
7258 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
7259 decls for now-static functions.
7260 * buffer.h (Fdelete_overlay): Remove decl.
7261 * callproc.c (Fgetenv_internal): Mark as internal.
7262 * composite.c (Fremove_list_of_text_properties): Remove decl.

7291 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
7292
7293 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
7294 change. (Bug#8496)
7295
7296 2011-04-13 Eli Zaretskii <eliz@gnu.org>
7297
7298 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
7299 when at ZV. (Bug#8487)
7300
7301 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
7302
7303 * charset.c (Fclear_charset_maps): Use xfree instead of free.
7304 (Bug#8437)
7305 * keyboard.c (parse_tool_bar_item): Likewise.
7306 * sound.c (sound_cleanup, alsa_close): Likewise.

7312 (overrun_check_free): Protoize.
7313
7314 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
7315
7316 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
7317 since callers should never pass a negative size.
7318 Change the signature to match that of plain 'read' and 'write'; see
7319 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
7320 * lisp.h: Update prototypes of emacs_write and emacs_read.
7321
7322 2011-04-11 Eli Zaretskii <eliz@gnu.org>
7323
7324 * xdisp.c (redisplay_window): Don't try to determine the character
7325 position of the scroll margin if the window start point w->startp
7326 is outside the buffer's accessible region. (Bug#8468)
7327
7328 2011-04-10 Eli Zaretskii <eliz@gnu.org>
7329
7330 Fix write-region and its subroutines for buffers > 2GB.
7331 * fileio.c (a_write, e_write): Modify declaration of arguments and
7332 local variables to support buffers larger than 2GB.
7333 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
7334
7335 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
7336 argument, local variables, and return value.
7337
7338 * lisp.h: Update prototypes of emacs_write and emacs_read.
7339
7340 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
7341
7342 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
7343
7344 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
7345
7346 Fix more problems found by GCC 4.6.0's static checks.
7347
7348 * xdisp.c (vmessage): Use a better test for character truncation.
7349
7350 * charset.c (load_charset_map): <, not <=, for optimization,
7351 and to avoid potential problems with integer overflow.
7352 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
7353 * casetab.c (set_identity, shuffle): Likewise.
7354 * editfns.c (Fformat): Likewise.
7355 * syntax.c (skip_chars): Likewise.
7356
7357 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
7358 This also lets GCC 4.6.0 generate slightly better loop code.
7359
7360 * callint.c (Fcall_interactively): <, not <=, for optimization.
7361 (Fcall_interactively): Count the number of arguments produced,
7362 not the number of arguments given. This is simpler and lets GCC
7363 4.6.0 generate slightly better code.
7364
7365 * ftfont.c: Distingish more carefully between FcChar8 and char.
7366 The previous code passed unsigned char * to a functions like
7367 strlen and xstrcasecmp that expect char *, which does not
7368 conform to the C standard.
7369 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
7370 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
7371 char * when the C standard requires it.
7372
7373 * keyboard.c (read_char): Remove unused var.
7374
7375 * eval.c: Port to Windows vsnprintf (Bug#8435).
7376 Include <limits.h>.
7377 (SIZE_MAX): Define if the headers do not.
7378 (verror): Do not give up if vsnprintf returns a negative count.
7379 Instead, grow the buffer. This ports to Windows vsnprintf, which
7380 does not conform to C99. Problem reported by Eli Zaretskii.
7381 Also, simplify the allocation scheme, by avoiding the need for
7382 calling realloc, and removing the ALLOCATED variable.
7383
7384 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
7385
7386 Remove invocations of doprnt, as Emacs now uses vsnprintf.
7387 But keep the doprint source code for now, as we might revamp it
7388 and use it again (Bug#8435).
7389 * lisp.h (doprnt): Remove.
7390 * Makefile.in (base_obj): Remove doprnt.o.
7391 * deps.mk (doprnt.o): Remove.
7392
7393 error: Print 32- and 64-bit integers portably (Bug#8435).
7394 Without this change, on typical 64-bit hosts error ("...%d...", N)
7395 was used to print both 32- and 64-bit integers N, which relied on
7396 undefined behavior.
7397 * lisp.h, src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h (pEd):
7398 New macro.
7399 * lisp.h (error, verror): Mark as printf-like functions.
7400 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
7401 Report overflow in size calculations when allocating printf buffer.
7402 Do not truncate output string at its first null byte.
7403 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
7404 Truncate the output at a character boundary, since vsnprintf does not
7405 do that.
7406 * charset.c (check_iso_charset_parameter): Convert internal
7407 character to string before calling 'error', since %c now has the
7408 printf meaning.
7409 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
7410 overflow when computing char to be passed to 'error'. Do not
7411 pass Lisp_Object to 'error'; pass the integer instead.
7412 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
7413 formatted with plain %d.
7414
7415 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
7416
7417 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
7418
7419 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
7420
7421 * xterm.c (x_catch_errors): Remove duplicate declaration.
7422
7423 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
7424
7425 * xdisp.c, lisp.h (message_nolog): Remove; unused.
7426
7427 2011-04-10 Jim Meyering <meyering@redhat.com>
7428
7429 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
7430 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
7431 return ssize_t not "int", and use size_t as the buffer length.
7432 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
7433 * gnutls.h: Update declarations.
7434 * process.c (read_process_output): Use ssize_t, to match.
7435 (send_process): Likewise.
7436
7437 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
7438
7439 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
7440
7441 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
7442
7443 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
7444 Use unsigned char, to match FcChar8 type definition.
7445
7446 * xterm.c (handle_one_xevent):
7447 * xmenu.c (create_and_show_popup_menu):
7448 * xselect.c (x_decline_selection_request)
7449 (x_reply_selection_request): Avoid type-punned deref of X events.
7450
7451 2011-04-09 Eli Zaretskii <eliz@gnu.org>
7452
7453 Fix some uses of `int' instead of EMACS_INT.
7454 * search.c (string_match_1, fast_string_match)
7455 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
7456 (scan_buffer, find_next_newline_no_quit)
7457 (find_before_next_newline, search_command, Freplace_match)
7458 (Fmatch_data): Make some `int' variables be EMACS_INT.
7459
7460 * xdisp.c (display_count_lines): 3rd argument and return value now
7461 EMACS_INT. All callers changed.
7462 (pint2hrstr): Last argument is now EMACS_INT.
7463
7464 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
7465 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
7466 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
7467 (decode_coding_utf_16, decode_coding_emacs_mule)
7468 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
7469 (decode_coding_ccl, decode_coding_charset)
7470 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
7471 (decode_coding_iso_2022, decode_coding_emacs_mule)
7472 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
7473 <char_offset, last_offset>: Declare EMACS_INT.
7474 (encode_coding_utf_8, encode_coding_utf_16)
7475 (encode_coding_emacs_mule, encode_invocation_designation)

7481 (encode_invocation_designation): Last argument P_NCHARS is now
7482 EMACS_INT.

7484 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
7485
7486 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
7487 All users changed.
7488

7497
7498 * process.c (Fformat_network_address): Doc fix.
7499
7500 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
7501

7503
7504 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
7505

7509 (syms_of_keyboard): Use DEFSYM macro.
7510
7511 * print.c (internal_with_output_to_temp_buffer): Function deleted.
7512

7516
7517 * process.c (Flist_processes): Remove to Lisp.

7541
7542 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
7543 printf-like functions.
7544 (tiff_load): Add casts to remove these marks before passing them
7545 to system-supplied API.

7547 * eval.c (Fsignal): Remove excess argument to 'fatal'.
7548
7549 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
7550 This avoids several warnings with gcc -Wstrict-overflow.
7551 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
7552 directly, rather than having caller test rule sign. This avoids
7553 some unnecessary tests.
7554 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
7555 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
7556 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
7557
7558 * xfont.c (xfont_text_extents): Remove var that was set but not used.
7559 (xfont_open): Avoid unnecessary tests.
7560
7561 * composite.c (composition_gstring_put_cache): Use unsigned integer.

7563 * composite.h, composite.c (composition_gstring_put_cache):
7564 Use EMACS_INT, not int, for length.
7565
7566 * composite.h (COMPOSITION_DECODE_REFS): New macro,
7567 breaking out part of COMPOSITION_DECODE_RULE.
7568 (COMPOSITION_DECODE_RULE): Use it.
7569 * composite.c (get_composition_id): Remove unused local vars,
7570 by using the new macro.
7571
7572 * textprop.c (set_text_properties_1): Change while to do-while,
7573 since the condition is always true at first.
7574
7575 * intervals.c (graft_intervals_into_buffer): Mark var as used.
7576 (interval_deletion_adjustment): Return unsigned value.
7577 All uses changed.
7578
7579 * process.c (list_processes_1, create_pty, read_process_output):
7580 (exec_sentinel): Remove vars that were set but not used.

7590
7591 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
7592 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
7593 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
7594
7595 * print.c (print_error_message): Avoid int overflow.
7596
7597 * font.c (font_list_entities): Redo for clarity,
7598 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
7599
7600 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
7601 (font_score): Avoid potential overflow in diff calculation.
7602
7603 * fns.c (substring_both): Remove var that is set but not used.
7604 (sxhash): Redo loop for clarity and to avoid wraparound warning.
7605
7606 * eval.c (funcall_lambda): Rename local to avoid shadowing.
7607
7608 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
7609 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
7610 can always succeed if overflow has undefined behavior.
7611
7612 * search.c (boyer_moore, wordify): Remove vars set but not used.
7613 (wordify): Omit three unnecessary tests.
7614
7615 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.

7631 but not used.
7632
7633 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):

7637
7638 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
7639
7640 * image.c (lookup_image): Remove var that is set but not used.
7641 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
7642
7643 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
7644 that are set but not used.
7645
7646 * xfns.c (make_invisible_cursor): Don't return garbage
7647 if XCreateBitmapFromData fails (Bug#8410).
7648
7649 * xselect.c (x_get_local_selection, x_handle_property_notify):
7650 Remove vars that are set but not used.
7651
7652 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
7653 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
7654
7655 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
7656 Remove var that is set but not used.
7657 (scroll_bar_windows_size): Now size_t, not int.
7658 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
7659 Check for overflow.
7660
7661 * xfaces.c (realize_named_face): Remove vars that are set but not used.
7662 (map_tty_color) [!defined MSDOS]: Likewise.
7663
7664 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
7665
7666 * coding.c: Remove vars that are set but not used.
7667 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
7668 All callers changed.
7669 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
7670 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
7671 (decode_coding_charset): Remove vars that are set but not used.
7672
7673 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
7674 that is set but not used.
7675
7676 * print.c (print_object): Remove var that is set but not used.
7677
7678 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
7679 The gnulib version avoids calling malloc in the usual case,
7680 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
7681 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
7682 * filelock.c (current_lock_owner): Likewise.
7683 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
7684 * sysdep.c: Include allocator.h, careadlinkat.h.
7685 (emacs_no_realloc_allocator): New static constant.
7686 (emacs_readlink): New function.
7687 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
7688 ../lib/careadlinkat.h.
7689
7690 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
7691
7692 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
7693 first non-nil return value).
7694
7695 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
7696
7697 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
7698 if not defined (Bug#8403).
7699
7700 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
7701
7702 * xdisp.c (display_count_lines): Remove parameter `start',
7703 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
7704 (get_char_face_and_encoding): Remove parameter `multibyte_p',
7705 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.

7718 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
7719
7720 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
7721
7722 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
7723
7724 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
7725 later (Bug#8403).
7726
7727 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
7728
7729 Add lexical binding.
7730
7731 * window.c (Ftemp_output_buffer_show): New fun.
7732 (Fsave_window_excursion):
7733 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
7734
7735 * lread.c (lisp_file_lexically_bound_p): New function.
7736 (Fload): Bind Qlexical_binding.
7737 (readevalloop): Remove `evalfun' arg.
7738 Bind Qinternal_interpreter_environment.
7739 (Feval_buffer): Bind Qlexical_binding.
7740 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
7741 Mark as dynamic.
7742 (syms_of_lread): Declare `lexical-binding'.
7743
7744 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
7745
7746 * keyboard.c (eval_dyn): New fun.
7747 (menu_item_eval_property): Use it.
7748
7749 * image.c (parse_image_spec): Use Ffunctionp.
7750
7751 * fns.c (concat, mapcar1): Accept byte-code-functions.
7752
7753 * eval.c (Fsetq): Handle lexical vars.
7754 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
7755 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
7756 (FletX, Flet): Obey lexical binding.
7757 (Fcommandp): Handle closures.
7758 (Feval): New `lexical' arg.
7759 (eval_sub): New function extracted from Feval. Use it almost
7760 everywhere where Feval was used. Look up vars in lexical env.
7761 Handle closures.
7762 (Ffunctionp): Move from subr.el.
7763 (Ffuncall): Handle closures.
7764 (apply_lambda): Remove `eval_flags'.
7765 (funcall_lambda): Handle closures and new byte-code-functions.
7766 (Fspecial_variable_p): New function.
7767 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
7768 but without exporting it to Lisp.
7769
7770 * doc.c (Fdocumentation, store_function_docstring):
7771 * data.c (Finteractive_form): Handle closures.
7772
7773 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
7774 interactive spec.
7775
7776 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
7777 New byte-codes.
7778 (exec_byte_code): New function extracted from Fbyte_code to handle new
7779 calling convention for byte-code-functions. Add new byte-codes.
7780
7781 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
7782
7783 * alloc.c (Fmake_symbol): Init new `declared_special' field.
7784
7785 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
7786
7787 * xdisp.c (redisplay_internal): Fix prototype.
7788
7789 2011-03-31 Eli Zaretskii <eliz@gnu.org>
7790
7791 * xdisp.c (SCROLL_LIMIT): New macro.
7792 (try_scrolling): Use it when setting scroll_limit.
7793 Limit scrolling to 100 screen lines.
7794 (redisplay_window): Even when falling back on "recentering",
7795 position point in the window according to scroll-conservatively,
7796 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
7797
7798 (try_scrolling): When point is above the window, allow searching
7799 as far as scroll_max, or one screenful, to compute vertical
7800 distance from PT to the scroll margin position. This prevents
7801 try_scrolling from unnecessarily failing when
7802 scroll-conservatively is set to a value slightly larger than the
7803 window height. Clean up the case of PT below the margin at bottom
7804 of window: scroll_max can no longer be INT_MAX. When aggressive
7805 scrolling is in use, don't let point enter the opposite scroll
7806 margin as result of the scroll.
7807 (syms_of_xdisp) <scroll-conservatively>: Document the
7808 threshold of 100 lines for never-recentering scrolling.
7809
7810 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
7811
7812 * dispextern.h (move_it_by_lines):
7813 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
7814 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
7815 (message_log_check_duplicate): Remove parameters `prev_bol' and
7816 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
7817 (redisplay_internal): Remove parameter `preserve_echo_area',
7818 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
7819
7820 * indent.c (Fvertical_motion):
7821 * window.c (window_scroll_pixel_based, Frecenter):
7822 Don't pass `need_y_p' to `move_it_by_lines'.
7823
7824 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
7825
7826 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
7827 steal a few bits to be more compact.
7828 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
7829 Remove unneeded casts.
7830
7831 * bytecode.c (Fbyte_code): CAR and CDR can GC.
7832
7833 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
7834
7835 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
7836 binding" message (bug#7967).
7837
7838 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
7839
7840 Fix more problems found by GCC 4.6.0's static checks.
7841
7842 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
7843 Remove unused local var.
7844
7845 * editfns.c (Fmessage_box): Remove unused local var.
7846
7847 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
7848 (note_mode_line_or_margin_highlight, note_mouse_highlight):
7849 Omit unused local vars.
7850 * window.c (shrink_windows): Omit unused local var.
7851 * menu.c (digest_single_submenu): Omit unused local var.
7852 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
7853 Omit unused local var.
7854
7855 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
7856 Don't assume string length fits in int.
7857 (keyremap_step, read_key_sequence): Use size_t for sizes.
7858 (read_key_sequence): Don't check last_real_key_start redundantly.
7859
7860 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
7861 instead of alloca (Bug#8344).
7862
7863 * eval.c (Fbacktrace): Don't assume nargs fits in int.
7864 (Fbacktrace_frame): Don't assume nframes fits in int.
7865
7866 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
7867
7868 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
7869 concerns.
7870
7871 * term.c (produce_glyphless_glyph): Remove unnecessary test.
7872
7873 * cm.c (calccost): Turn while-do into do-while, for clarity.
7874
7875 * keyboard.c (syms_of_keyboard): Use the same style as later
7876 in this function when indexing through an array. This also
7877 works around GCC bug 48267.
7878
7879 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
7880
7881 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
7882
7883 * chartab.c (sub_char_table_ref_and_range): Redo for slight
7884 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
7885
7886 * keyboard.c, keyboard.h (num_input_events): Now size_t.
7887 This avoids undefined behavior on integer overflow, and is a bit
7888 more convenient anyway since it is compared to a size_t variable.
7889
7890 Variadic C functions now count arguments with size_t, not int.
7891 This avoids an unnecessary limitation on 64-bit machines, which
7892 caused (substring ...) to crash on large vectors (Bug#8344).
7893 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
7894 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
7895 All variadic functions and their callers changed accordingly.
7896 (struct gcpro.nvars): Now size_t, not int. All uses changed.
7897 * data.c (arith_driver, float_arith_driver): Likewise.
7898 * editfns.c (general_insert_function): Likewise.
7899 * eval.c (struct backtrace.nargs, interactive_p)
7900 (internal_condition_case_n, run_hook_with_args, apply_lambda)
7901 (funcall_lambda, mark_backtrace): Likewise.
7902 * fns.c (concat): Likewise.
7903 * frame.c (x_set_frame_parameters): Likewise.

8120 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
8121
8122 Fix more problems found by GCC 4.5.2's static checks.
8123
8124 * coding.c (encode_coding_raw_text): Avoid unnecessary test
8125 the first time through the loop, since we know p0 < p1 then.
8126 This also avoids a gcc -Wstrict-overflow warning.
8127
8128 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
8129 leading to a memory leak, possible in functions like
8130 load_charset_map_from_file that can allocate an unbounded number
8131 of objects (Bug#8318).
8132
8133 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
8134 that could (at least in theory) be that large.
8135
8136 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
8137 This is less likely to overflow, and avoids undefined behavior if
8138 overflow does occur. All callers changed. Use strtoul to scan
8139 for the unsigned long integer.
8140 (pint2hrstr): Simplify and tune code slightly.
8141 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
8142

8155
8156 * process.c (Fmake_network_process): Use socklen_t, not int,
8157 where POSIX says socklen_t is required in portable programs.
8158 This fixes a porting bug on hosts like 64-bit HP-UX, where
8159 socklen_t is wider than int (Bug#8277).
8160 (Fmake_network_process, server_accept_connection):
8161 (wait_reading_process_output, read_process_output):
8162 Likewise.
8163
8164 * process.c: Rename or move locals to avoid shadowing.

8171 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
8172 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
8173
8174 Make tparam.h and terminfo.c consistent.
8175 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
8176 Include tparam.h instead, since it declares them.
8177 * cm.h (PC): Remove extern decl; tparam.h now does this.
8178 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
8179 * terminfo.c: Include tparam.h, to check interfaces.
8180 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
8181 (tparam): Adjust signature to match interface in tparam.h;
8182 this removes some undefined behavior. Check that outstring and len
8183 are zero, which they always are with Emacs.
8184 * tparam.h (PC, BC, UP): New extern decls.
8185
8186 * xftfont.c (xftfont_shape): Now static, and defined only if needed.

8200
8201 * composite.c (composition_compute_stop_pos): Rename local to
8202 avoid shadowing.
8203 (composition_reseat_it): Remove unused locals.
8204 (find_automatic_composition, composition_adjust_point): Likewise.
8205 (composition_update_it): Mark var as initialized.
8206 (find_automatic_composition): Mark vars as initialized,
8207 with a FIXME (Bug#8290).
8208
8209 character.h: Rename locals to avoid shadowing.
8210 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
8211 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
8212 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
8213 (BUF_DEC_POS): Be more systematic about renaming local temporaries
8214 to avoid shadowing.
8215
8216 * textprop.c (property_change_between_p): Remove; unused.
8217
8218 * intervals.c (interval_start_pos): Now static.

8223 Rename locals to avoid shadowing.
8224
8225 * sound.c (wav_play, au_play, Fplay_sound_internal):
8226 Fix pointer signedness.
8227 (alsa_choose_format): Remove unused local var.
8228 (wav_play): Initialize a variable to 0, to prevent undefined
8229 behavior (Bug#8278).
8230
8231 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
8232
8233 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
8234
8235 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
8236 clobbering (Bug#8298).
8237 * sysdep.c (sys_subshell): Likewise.
8238 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
8239
8240 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
8241 This should get cleaned up, so that child_setup has the
8242 same signature on all platforms.
8243
8244 * callproc.c (call_process_cleanup): Now static.
8245 (relocate_fd): Rename locals to avoid shadowing.
8246
8247 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
8248
8249 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
8250 not to be necessary, and produces flickering.
8251

8253
8254 * config.in: Remove file.
8255

8286 (sigchld_handler): Now static.
8287
8288 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
8289 That way, the code declares only the vars that it needs.

8291 * s/cygwin.h (PTY_ITERATION): Likewise.
8292 * s/darwin.h (PTY_ITERATION): Likewise.
8293 * s/gnu-linux.h (PTY_ITERATION): Likewise.
8294
8295 * s/irix6-5.h (PTY_OPEN): Declare stb, to loosen coupling.
8296 * process.c (allocate_pty): Don't declare stb unless it's needed.
8297
8298 * bytecode.c (MAYBE_GC): Rewrite so as not to use empty "else".
8299 (CONSTANTLIM): Remove; unused.
8300 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
8301 Define only if needed.
8302
8303 * unexelf.c (unexec): Name an expression,
8304 to avoid gcc -Wbad-function-cast warning.

8306 n rather than nn, a way that does not involve shadowing.
8307 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
8308
8309 * deps.mk (unexalpha.o): Remove; unused.

8371 Move decls here, to check interfaces.
8372 * process.c (get_operating_system_release): Move decl to lisp.h.
8373 * xrdb.c (get_system_name): Likewise.
8374 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
8375 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
8376 some of which prompt warnings from gcc -Wbad-function-cast.
8377 (Fformat_time_string, Fencode_time, Finsert_char):
8378 (Ftranslate_region_internal, Fformat):

8386 ENABLE_CHECKING is not defined.
8387

8406 (Fmemory_limit): Cast sbrk's returned value to char *.
8407
8408 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

8410
8411 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
8412
8413 Use functions, not macros, for up- and down-casing (Bug#8254).
8414 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
8415 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
8416 to use the following functions instead of these macros.
8417 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
8418 EMACS_INT, since callers assume the returned value fits in int.
8419 (upcase1): Likewise, for UPCASE_TABLE.
8420 (uppercasep, lowercasep, upcase): New static inline functions.
8421 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

8427 (regex_compile, re_search_2, re_match_2_internal):
8428 Remove unused local vars.

8430 which gcc can warn about.
8431 (regex_compile, re_match_2_internal): Mark locals as initialized.
8432 (RETALLOC_IF): Define only if needed.
8433 (WORDCHAR_P): Likewise. This one is never needed, but is used
8434 only in a comment talking about a compiler bug, so put inside
8435 the #if 0 of that comment.
8436 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
8437 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
8438 Remove; unused.

8450 * character.h (INC_POS, DEC_POS): Rename locals to avoid shadowing.
8451
8452 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
8453 All uses changed.
8454 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
8455 Rename locals to avoid shadowing.
8456 (Fvertical_motion): Mark locals as initialized.
8457
8458 * casefiddle.c (casify_object, casify_region): Now static.

8462
8463 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
8464 New macros, so that the caller can use some names other than
8465 gcpro1, gcpro2, etc.
8466 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
8467 of the new macros.
8468 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
8469 argument, for consistency with GCPRO2_VAR, etc: it is now the
8470 prefix of the variable, not the variable itself. All uses
8471 changed.
8472 * dired.c (directory_files_internal, file_name_completion):
8473 Rename locals to avoid shadowing.
8474
8475 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
8476 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
8477 dired.c's scmp function, had undefined behavior.
8478 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
8479 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
8480 * buffer.h: ... to here, because these macros use current_buffer,
8481 and the new implementation with inline functions needs to have
8482 current_buffer in scope now, rather than later when the macros
8483 are used.
8484 (downcase, upcase1): New static inline functions.
8485 (DOWNCASE, UPCASE1): Reimplement using these functions.
8486 This avoids undefined behavior in expressions like
8487 DOWNCASE (x) == DOWNCASE (y), which previously suffered
8488 from race conditions in accessing the global variables
8489 case_temp1 and case_temp2.
8490 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
8491 * lisp.h (case_temp1, case_temp2): Remove their decls.
8492 * character.h (ASCII_CHAR_P): Move from here ...
8493 * lisp.h: ... to here, so that the inline functions mentioned
8494 above can use them.
8495
8496 * dired.c (directory_files_internal_unwind): Now static.
8497
8498 * fileio.c (file_name_as_directory, directory_file_name):
8499 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
8500 Now static.
8501 (file_name_as_directory): Use const pointers when appropriate.
8502 (Fexpand_file_name): Likewise. In particular, newdir might
8503 point at constant storage, so make it a const pointer.
8504 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
8505 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
8506 signedness issues.
8507 (Fset_file_times, Finsert_file_contents, auto_save_error):
8508 Rename locals to avoid shadowing.

8511 (Ftry_completion, Fall_completions): Rename or remove locals
8512 to avoid shadowing.
8513
8514 * marker.c (bytepos_to_charpos): Remove; unused.
8515
8516 * lisp.h (verify_bytepos, count_markers): New decls,
8517 so that gcc does not warn that these functions aren't declared.
8518
8519 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
8520 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
8521 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
8522 (copy_text): Remove unused local var.
8523
8524 * filelock.c (within_one_second): Now static.
8525 (lock_file_1): Rename local to avoid shadowing.
8526
8527 * buffer.c (fix_overlays_before): Mark locals as initialized.
8528 (fix_start_end_in_overlays): Likewise. This function should be
8529 simplified by using pointers-to-pointers, but that's a different
8530 matter.
8531 (switch_to_buffer_1): Now static.
8532 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
8533 (report_overlay_modification): Rename locals to avoid shadowing.
8534
8535 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
8536 Fix pointer signedness issue.
8537 (sys_subshell): Mark local as volatile if checking for lint,
8538 to suppress a gcc -Wclobbered warning that does not seem to be right.
8539 (MAXPATHLEN): Define only if needed.
8540
8541 * process.c (serial_open, serial_configure): Move decls from here ...
8542 * systty.h: ... to here, so that they can be checked.
8543
8544 * fns.c (get_random, seed_random): Move extern decls from here ...
8545 * lisp.h: ... to here, so that they can be checked.
8546
8547 * sysdep.c (reset_io): Now static.
8548 (wait_for_termination_signal): Remove; unused.
8549
8550 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
8551 (copy_keymap_item, append_key, push_text_char_description):
8552 Now static.
8553 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
8554 (DENSE_TABLE_SIZE): Remove; unused.
8555 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
8556 (describe_map_tree):
8557 Rename locals to avoid shadowing.
8558
8559 * keyboard.c: Declare functions static if they are not used elsewhere.
8560 (echo_char, echo_dash, cmd_error, top_level_2):
8561 (poll_for_input, handle_async_input): Now static.
8562 (read_char, kbd_buffer_get_event, make_lispy_position):
8563 (make_lispy_event, make_lispy_movement, apply_modifiers):
8564 (decode_keyboard_code, tty_read_avail_input, menu_bar_items):

8575
8576 * emacs.c (init_cmdargs): Rename local to avoid shadowing.
8577 (DEFINE_DUMMY_FUNCTION): New macro.
8578 (__do_global_ctors, __do_global_ctors_aux, __do_global_dtors, __main):
8579 Use it.
8580 (main): Add casts to avoid warnings
8581 if GCC considers string literals to be constants.
8582
8583 * lisp.h (fatal_error_signal): Add decl, since it's exported.
8584
8585 * dbusbind.c: Pointer signedness fixes.
8586 (xd_signature, xd_append_arg, xd_initialize):
8587 (Fdbus_call_method, Fdbus_call_method_asynchronously):

8706 For example, without this patch (encode-time 0 0 0 1 1
8707 1152921504606846976) returns the obviously-bogus value (-948597
8708 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
8709 reports time overflow. See
8710 <http://lists.gnu.org/archive/html/emacs-devel/2011-03/msg00470.html>.
8711 * deps.mk (editfns.o): Depend on ../lib/intprops.h.

8726 * editfns.c (time_overflow): New function, refactoring common code.
8727 (Fformat_time_string, Fdecode_time, Fencode_time):
