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

501
502 * xdisp.c (x_write_glyphs, draw_phys_cursor_glyph)
503 (erase_phys_cursor, update_window_cursor, show_mouse_face)
504 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
505 behave as if the cursor position were at the window margin.
506
507 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
508 and the cursor position is out of bounds, behave as if the cursor
509 position were at the window margin. (Bug#10075)
510
511 2011-11-18 Chong Yidong <cyd@gnu.org>
512
513 * window.c (Fwindow_combination_limit): Make first argument
514 non-optional, since it is meaningless for live windows like the
515 selected window.

532 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
533
534 * xdisp.c (row_hash): New function, body extracted from
535 compute_line_metrics.
536 (compute_line_metrics): Call row_hash, instead of computing the
537 hash code inline.
538
539 * dispnew.c (verify_row_hash): Call row_hash for computing the
540 hash code of a row, instead of duplicating code from xdisp.c.
541
542 * dispextern.h (row_hash): Add prototype.
543
544 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>

572 (Fsplit_window_internal, saved_window)
573 (Fset_window_configuration, save_window_save): Rename all
574 occurrences of window_nest to window_combination_limit.

579
580 2011-11-14 Eli Zaretskii <eliz@gnu.org>
581
582 * xdisp.c (display_line): Move the call to
583 highlight_trailing_whitespace before the call to
584 compute_line_metrics, since the latter needs to see the final
585 faces of all the glyphs to compute ROW's hash value.
586 Fixes assertion violations in row_equal_p. (Bug#10035)
587
588 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
589
590 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
591 just return (bug#10044).
592
593 2011-11-12 Eli Zaretskii <eliz@gnu.org>
594
595 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
596 with user-defined heap size. Bump the default size of the temacs
597 heap to 27MB, to avoid memory warning when running temacs.
598 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
599
600 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
601 current_matrix and desired_matrix. (Bug#9990)
602 (verify_row_hash) [XASSERTS]: New function.

631 process_coding.
632
633 2011-11-11 Johan Bockgård <bojohan@gnu.org>

636 avoid a crash (bug#9496).
637
638 2011-11-09 Chong Yidong <cyd@gnu.org>

648
649 Avoid some portability problems by eschewing 'extern inline' functions.
650 The trivial performance wins aren't worth the portability hassles; see
651 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
652 et seq.
653 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

700
701 * alloc.c (DEADP): New macro, for porting to GNU/Hurd (Bug#9926).
702 This is also needed for porting to any host where GC_MARK_STACK is
703 not GC_MAKE_GCPROS_NOOPS.
704 (which_symbols): Use it.
705
706 2011-11-07 Kenichi Handa <handa@m17n.org>

718
719 * xmenu.c (cleanup_widget_value_tree): New function.
720 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of

722
723 2011-11-06 Paul Eggert <eggert@cs.ucla.edu>
724

727 (window_box_width, window_box_left, window_box_left_offset)
728 (window_box_right, window_box_right_offset): Declare extern.
729 Otherwise, these inline functions do not conform to C99 and
730 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
731 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
732 * intervals.c (adjust_intervals_for_insertion)
733 (adjust_intervals_for_deletion): Now extern, because otherwise the
734 extern inline functions 'offset_intervals' couldn't refer to it.
735 (static_offset_intervals): Remove.
736 (offset_intervals): Rewrite using the old contents of
737 static_offset_intervals. The old version didn't conform to C99
738 because an extern inline function contained a reference to an
739 identifier with static linkage.

759 (Fwindow_new_normal, Fwindow_left_column, Fwindow_top_line)
760 (Fwindow_margins, Fwindow_fringes, Fwindow_scroll_bars)
761 (Fwindow_vscroll): Doc fix.
762 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
763 argument, since it makes no sense to pass a live window and for
764 consistency with window-child.

796 Move terminal->reference_count++ just before making the frame official
797 (Bug#9943).

805 official. Move initialization of image_cache_refcount and
806 dpyinfo_refcount before calling init_frame_faces (Bug#9943).
807
808 2011-11-05 Eli Zaretskii <eliz@gnu.org>
809
810 Support MSVC build with newer versions of Visual Studio.
811 * makefile.w32-in (TAGS-gmake): Don't use $(patsubst ...), as

883 2011-10-30 Eli Zaretskii <eliz@gnu.org>
884
885 * xdisp.c (try_cursor_movement): Make sure ROW isn't decremented
886 past the beginning of the current glyph matrix.
887
888 2011-10-30 Adam Sjøgren <asjo@koldfront.dk> (tiny change)
889
890 * xterm.c: Include X11/Xproto.h if HAVE_GTK3.
891 (x_error_handler): Ignore BadMatch for X_SetInputFocus for
892 HAVE_GTK3 (Bug#9869).
893
894 * gtkutil.c (xg_win_to_widget, xg_event_is_for_menubar): Initialize
895 type to GDK_NOTHING so valgrind does not complain (Bug#9901).
896
897 * xterm.h (x_display_info): Add Xatom_net_wm_state_hidden (Bug#9893).
898
899 * xterm.c: Declare x_handle_net_wm_state to return int.
900 (handle_one_xevent): Check if we are iconified but don't have
901 _NET_WM_STATE_HIDDEN. If do, treat as deiconify (Bug#9893).
902 (get_current_wm_state): Return non-zero if not hidden,
903 check for _NET_WM_STATE_HIDDEN (Bug#9893).
904 (do_ewmh_fullscreen): Ignore return value from get_current_wm_state.
905 (x_handle_net_wm_state): Return what get_current_wm_state returns.
906 (x_term_init): Initialize dpyinfo->Xatom_net_wm_state_hidden.
907
908 2011-10-29 Paul Eggert <eggert@cs.ucla.edu>
909
910 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
911 so that this new function doesn't get optimized away by a
912 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
913
914 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
915
916 * frame.h (MOUSE_HL_INFO): Remove excess parens.
917
918 2011-10-29 Eli Zaretskii <eliz@gnu.org>
919
920 Fix the `xbytecode' command.
921 * .gdbinit (xprintbytestr): New command.
922 (xwhichsymbols): Rename from `which'; all callers changed.
923 (xbytecode): Print the byte-code string as well.
924
925 2011-10-29 Kim Storm <storm@cua.dk>
926
927 * alloc.c (which_symbols): New function.
928
929 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
930

932 line. (Bug#9903)
933
934 2011-10-29 Glenn Morris <rgm@gnu.org>
935
936 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
937 Not clear what it was for, and it causes various bugs. (Bug#9839)
938
939 2011-10-28 Eli Zaretskii <eliz@gnu.org>
940
941 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
942 possible random value that matches one of those tested as
943 condition to clear the mouse face.
944
945 2011-10-28 Chong Yidong <cyd@gnu.org>
946
947 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.
948
949 2011-10-28 Dan Nicolaescu <dann@ics.uci.edu>
950
951 * window.c (make_window): Initialize phys_cursor_on_p.
952

960
961 2011-10-28 Eli Zaretskii <eliz@gnu.org>
962
963 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
964 <oslsachem@gmail.com> for helping to debug this.
965
966 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
967 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
968 (g_b_init_get_glyph_outline_w): New static variables.
969 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
970 (GetGlyphOutlineW_Proc): New typedefs.
971 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
972 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
973 New functions.
974 (w32font_open_internal, compute_metrics):
975 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
976 instead of calling the "wide" APIs directly.
977
978 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
979
980 * w32.h (syms_of_w32font): Add prototype.
981
982 2011-10-27 Juanma Barranquero <lekktu@gmail.com>

985 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
986 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
987 (Fmove_to_window_line): Doc fix.
988
989 2011-10-27 Chong Yidong <cyd@gnu.org>
990
991 * process.c (make_process): Set gnutls_state to NULL.
992
993 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
994 non-NULL, regardless of GNUTLS_INITSTAGE.
995 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
996 an error. Set process slots as soon as we allocate them.
997
998 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
999
1000 2011-10-27 Chong Yidong <cyd@gnu.org>
1001
1002 * gnutls.c (emacs_gnutls_deinit): New function.
1003 Deallocate credentials structures as well as calling gnutls_deinit.
1004 (Fgnutls_deinit, Fgnutls_boot): Use it.
1005
1006 * process.c (make_process): Initialize GnuTLS credentials to NULL.
1007 (deactivate_process): Call emacs_gnutls_deinit.
1008
1009 2011-10-27 Juanma Barranquero <lekktu@gmail.com>

1019 extracted from Fw32_default_color_map.
1020 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
1021
1022 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
1023
1024 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
1025
1026 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
1027
1028 * keyboard.c (test_undefined): New function (bug#9751).

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

1303
1304 2011-09-27 Eli Zaretskii <eliz@gnu.org>
1305
1306 * xdisp.c (handle_invisible_prop): If invisible text ends on a
1307 newline, reseat the iterator instead of bidi-iterating there one
1308 character at a time. (Bug#9610)
1309 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
1310 TO_CHARPOS if the bidi iterator is at base embedding level.
1311
1312 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>

1344 Default value is now t. Doc fix.
1345
1346 * indent.c (Fvertical_motion): Compute and apply the overshoot
1347 logic when moving up, not only when moving down. Fix the
1348 confusing name and values of the it_overshoot_expected variable;
1349 logic changes accordingly. (Bug#9254) (Bug#9549)
1350
1351 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
1352 CHARPOS is covered by a display string which includes newlines.
1353 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS

1363 2011-09-24 Jim Meyering <meyering@redhat.com>
1364
1365 do not ignore write error for any output size
1366 The previous change was incomplete.
1367 While it makes emacs --batch detect the vast majority of stdout
1368 write failures, errors were still ignored whenever the output size is
1369 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
1370 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
1371 && echo FAIL: ignored write error
1372 FAIL: ignored write error
1373 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
1374 && echo FAIL: ignored write error
1375 FAIL: ignored write error
1376 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
1377
1378 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
1379
1380 * emacs.c (Fkill_emacs): In noninteractive mode exit
1381 non-successfully if a write error occurred on stdout. (Bug#9574)
1382
1383 2011-09-21 Eli Zaretskii <eliz@gnu.org>
1384
1385 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
1386 the xassert test.
1387
1388 * dispextern.h (struct it): Update the comment documenting what
1389 can it->OBJECT be.
1390
1391 2011-09-20 Eli Zaretskii <eliz@gnu.org>
1392
1393 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
1394 a display string, extend search for cursor position to end of row.
1395 (find_row_edges): If the row ends in a newline from a display
1396 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
1397 Handle the case of a display string with multiple newlines.
1398 (Fcurrent_bidi_paragraph_direction): Fix search for previous
1399 non-empty line. Fixes confusing cursor motion with arrow keys at
1400 the beginning of a line that starts with whitespace.
1401
1402 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>

1411
1412 2011-09-18 Eli Zaretskii <eliz@gnu.org>
1413
1414 * xdisp.c (display_line): Record maximum and minimum buffer
1415 positions even if no glyphs were produced (e.g., by a zero-width
1416 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
1417 buffer positions that will be removed from the glyph row because
1418 they don't fit.
1419 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
1420 column is beyond frame width: don't subtract 1 "pixel" when
1421 computing width of the stretch.
1422 (reseat_at_next_visible_line_start): Undo the change made on
1423 2011-09-17 that saved paragraph information and restored it after
1424 the call to `reseat'. (Bug#9545)
1425
1426 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>

1432
1433 * search.c (boyer_moore): Take unibyte characters from pattern

1442 Fix minor problem found by static checking.
1443 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
1444 initialized, to pacify gcc -Wuninitialized.
1445
1446 * fileio.c: Report proper errno when syscall falls.
1447 (Finsert_file_contents): Save and restore errno,
1448 so that report_file_error outputs the correct diagnostic.
1449 (Fwrite_region) [CLASH_DETECTION]: Likewise.
1450
1451 2011-09-18 Eli Zaretskii <eliz@gnu.org>

1459
1460 2011-09-17 Eli Zaretskii <eliz@gnu.org>
1461
1462 * xdisp.c (reseat_at_next_visible_line_start): Keep information
1463 about the current paragraph and restore it after the call to reseat.

1465 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
1466 (bidi_find_paragraph_start): Search back for paragraph beginning
1467 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
1468 (bidi_move_to_visually_next): Only trigger paragraph-related
1469 computations when the last character is a newline or at EOB, not
1470 just any NEUTRAL_B. (Bug#9470)
1471
1472 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
1473 truncated lines if point is covered by a display string. (Bug#9524)
1474
1475 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
1476
1477 * xselect.c: Relax test for outgoing X longs (Bug#9498).
1478 (cons_to_x_long): New function.
1479 (lisp_data_to_selection_data): Use it. Correct the test for
1480 short-versus-long data; it was negated. Break out of vector
1481 loop, for efficiency, when a long datum is discovered.
1482
1483 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
1484
1485 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
1486
1487 2011-09-16 Eli Zaretskii <eliz@gnu.org>
1488
1489 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
1490 GCC PR/17406) by declaring this function with external scope.
1491
1492 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
1493
1494 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
1495 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
1496
1497 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
1498

1532 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
1533
1534 * xselect.c: Use signed conversions more consistently (Bug#9498).
1535 (selection_data_to_lisp_data): Assume incoming selection data are
1536 signed integers, not unsigned. This is to be consistent with
1537 outgoing selection data, which was modified to use signed integers
1538 in as part of the fix to Bug#9196 in response to Jan D.'s comment
1539 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
1540 expects long, not unsigned long.

1562
1563 * minibuf.c (Fread_from_minibuffer): Doc fix.
1564
1565 2011-09-11 Eli Zaretskii <eliz@gnu.org>
1566
1567 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
1568 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
1569
1570 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
1571
1572 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
1573 value for non-existent files.
1574
1575 2011-09-11 Eli Zaretskii <eliz@gnu.org>
1576
1577 * fileio.c (Finsert_file_contents): If the file cannot be opened,
1578 set its "size" to -1. This will set the modtime_size field of
1579 the corresponding buffer to -1, which is what
1580 verify-visited-file-modtime expects for files that do not exist.
1581 (Bug#9139)
1582
1583 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
1584
1585 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
1586 here ...
1587 * lisp.h: ... from here. push_key_description is no longer
1588 defined in keyboard.c, so its declaration should not be in
1589 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
1590 logically belongs with push_key_description.
1591
1592 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
1593
1594 * buffer.h: Include <sys/types.h> instead of <time.h>.

1612
1613 2011-09-09 Eli Zaretskii <eliz@gnu.org>

1620 Operate on live windows only.
1621
1622 2011-09-08 Juanma Barranquero <lekktu@gmail.com>

1636
1637 isnan: Fix porting problem to Solaris 10 with bundled gcc.
1638 Without this fix, the command to link temacs failed due to an
1639 undefined symbol __builtin_isnan. This is because
1640 /usr/include/iso/math_c99.h #defines isnan(x) to
1641 __builtin_isnan(x), but the bundled gcc, which identifies itself
1642 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
1643 a __builtin_isnan.
1644 * floatfns.c (isnan): #undef, and then #define to a clone of
1645 what's in data.c.
1646 (Fisnan): Always define, since it's always available now.
1647 (syms_of_floatfns): Always define isnan at the Lisp level.
1648
1649 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
1650
1651 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
1652
1653 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
1654
1655 * fileio.c: Fix bugs with large file offsets (Bug#9428).
1656 The previous code assumed that file offsets (off_t values) fit in
1657 EMACS_INT variables, which is not true on typical 32-bit hosts.
1658 The code messed up by falsely reporting buffer overflow in cases
1659 such as (insert-file-contents "big" nil 1 2) into an empty buffer
1660 when "big" contains more than 2**29 bytes, even though this
1661 inserts just one byte and does not overflow the buffer.
1662 (Finsert_file_contents): Store file offsets as off_t
1663 values, not as EMACS_INT values. Check for overflow when
1664 converting between EMACS_INT and off_t. When checking for
1665 buffer overflow or for overlap, take the offsets into account.
1666 Don't use EMACS_INT for small values where int suffices.
1667 When checking for overlap, fix a typo: ZV was used where
1668 ZV_BYTE was intended.
1669 (Fwrite_region): Don't assume off_t fits into 'long'.
1670 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
1671
1672 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
1673
1674 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
1675
1676 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
1677
1678 sprintf-related integer and memory overflow issues (Bug#9412).
1679
1680 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
1681 (esprintf, exprintf, evxprintf): New functions.
1682 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
1683 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
1684 (modify_event_symbol): Do not assume that the length of
1685 name_alist_or_stem is safe to alloca and fits in int.
1686 (Fexecute_extended_command): Likewise for function name and binding.
1687 (Frecursion_depth): Wrap around reliably on integer overflow.
1688 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
1689 since some callers pass EMACS_INT values.
1690 (Fsingle_key_description): Don't crash if symbol name contains more
1691 than MAX_ALLOCA bytes.
1692 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
1693 (get_minibuffer): Arg is now EMACS_INT, not int.
1694 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
1695 (esprintf, exprintf, evxprintf): New decls.
1696 * window.h (command_loop_level, minibuf_level): Reflect API changes.
1697
1698 * dbusbind.c (signature_cat): New function.
1699 (xd_signature, Fdbus_register_signal):
1700 Do not overrun buffer; instead, report string overflow.
1701
1702 * dispnew.c (add_window_display_history): Don't overrun buffer.
1703 Truncate instead; this is OK since it's just a log.
1704
1705 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
1706 even if the time zone offset is outlandishly large.
1707 Don't mishandle offset == INT_MIN.
1708
1709 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
1710 when creating daemon; the previous buffer-overflow check was incorrect.
1711
1712 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
1713 which has the guts of the old verror function.
1714
1715 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
1716 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
1717
1718 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
1719 (font_unparse_xlfd): Don't blindly alloca long strings.
1720 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
1721 fits in int, when using sprintf. Use single snprintf to count
1722 length of string rather than counting it via multiple sprintfs;
1723 that's simpler and more reliable.
1724 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
1725 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
1726 sprintf, in case result does not fit in int.
1727
1728 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
1729 (fontset_from_font): Print it.
1730
1731 * frame.c (tty_frame_count): Now printmax_t, not int.
1732 (make_terminal_frame, set_term_frame_name): Print it.
1733 (x_report_frame_params): In X, window IDs are unsigned long,
1734 not signed long, so print them as unsigned.
1735 (validate_x_resource_name): Check for implausibly long names,
1736 and don't assume name length fits in 'int'.
1737 (x_get_resource_string): Don't blindly alloca invocation name;
1738 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
1739 not fit in int.
1740
1741 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
1742 (xg_check_special_colors, xg_set_geometry):
1743 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
1744
1745 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
1746 Use esprintf, not sprintf, in case result does not fit in int.
1747
1748 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
1749 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
1750 it as a large positive number.
1751 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
1752 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
1753
1754 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
1755 in case result does not fit in int.
1756
1757 * print.c (float_to_string): Detect width overflow more reliably.
1758 (print_object): Make sprintf buffer a bit bigger, to avoid potential
1759 buffer overrun. Don't assume list length fits in 'int'. Treat
1760 print length of 0 as 0, not as infinity; to be consistent with other
1761 uses of print length in this function. Don't overflow print length
1762 index. Don't assume hash table size fits in 'long', or that
1763 vectorlike size fits in 'unsigned long'.
1764
1765 * process.c (make_process): Use printmax_t, not int, to format
1766 process-name gensyms.
1767
1768 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
1769
1770 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
1771 to avoid potential buffer overrun.
1772
1773 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
1774 if X resource line is longer than 512 bytes.
1775
1776 * xfns.c (x_window): Make sprintf buffer a bit bigger
1777 to avoid potential buffer overrun.
1778
1779 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
1780

1783 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
1784
1785 Integer overflow fixes for scrolling, etc.
1786 Without these, Emacs silently mishandles large integers sometimes.
1787 For example, "C-u 4294967297 M-x recenter" was treated as if
1788 it were "C-u 1 M-x recenter" on a typical 64-bit host.
1789
1790 * xdisp.c (try_window_id): Check Emacs fixnum range before
1791 converting to 'int'.
1792
1793 * window.c (window_scroll_line_based, Frecenter):
1794 Check that an Emacs fixnum is in range before assigning it to 'int'.
1795 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
1796 values converted from Emacs fixnums.
1797 (Frecenter): Don't wrap around a line count if it is out of 'int'
1798 range; instead, treat it as an extreme value.
1799 (Fset_window_configuration, compare_window_configurations):
1800 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
1801
1802 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
1803 that can exceed INT_MAX. Check that EMACS_INT value is in range
1804 before assigning it to the (possibly-narrower) index.
1805 (match_limit): Don't assume that a fixnum can fit in 'int'.
1806
1807 * print.c (print_object): Use ptrdiff_t, not int, for index that can
1808 exceed INT_MAX.
1809
1810 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
1811 (Fvertical_motion): Don't wrap around LINES values that don't fit
1812 in 'int'. Instead, treat them as extreme values. This is good
1813 enough for windows, which can't have more than INT_MAX lines anyway.
1814
1815 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
1816
1817 * Require libxml/parser.h to avoid compilation warning.
1818
1819 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
1820
1821 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
1822 since this reportedly can destroy thread storage.
1823
1824 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
1825
1826 * syntax.c (find_defun_start): Update all cache variables if
1827 exiting early (Bug#9401).
1828
1829 2011-08-30 Eli Zaretskii <eliz@gnu.org>
1830
1831 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
1832
1833 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
1834 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
1835 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
1836
1837 * term.c (tty_append_glyph): New function.
1838 (produce_stretch_glyph): Static function and its prototype deleted.
1839
1840 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
1841 Add prototypes.
1842
1843 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
1844
1845 * image.c (parse_image_spec): Check for nonnegative, not for positive,
1846 when checking :margin (Bug#9390).
1847 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
1848 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
1849 so that the name doesn't mislead. All uses changed.
1850
1851 2011-08-28 Johan Bockgård <bojohan@gnu.org>
1852
1853 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
1854 set_tty_hooks.
1855
1856 2011-08-27 Eli Zaretskii <eliz@gnu.org>
1857
1858 * xdisp.c (move_it_to): Don't bail out early when reaching
1859 position beyond to_charpos, if we are scanning backwards.
1860 (move_it_vertically_backward): When DY == 0, make sure we get to
1861 the first character in the line after the newline.
1862
1863 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
1864
1865 * ccl.c: Improve and simplify overflow checking (Bug#9196).
1866 (ccl_driver): Do not generate an out-of-range pointer.
1867 (Fccl_execute_on_string): Remove unnecessary check for
1868 integer overflow, noted by Stefan Monnier in
1869 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
1870 Remove a FIXME that didn't need fixing.
1871 Simplify the newly-introduced buffer reallocation code.
1872
1873 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
1874
1875 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
1876
1877 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
1878
1879 Integer and memory overflow issues (Bug#9196).
1880
1881 * doc.c (get_doc_string): Rework so that
1882 get_doc_string_buffer_size is the actual buffer size, rather than
1883 being 1 less than the actual buffer size; this makes xpalloc more
1884 convenient.
1885
1886 * image.c (x_allocate_bitmap_record, cache_image):
1887 * xselect.c (Fx_register_dnd_atom):
1888 Simplify previous changes by using xpalloc.
1889
1890 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
1891 since either will do and ptrdiff_t is convenient with xpalloc.
1892
1893 * charset.c (charset_table_size)
1894 (struct charset_sort_data.priority): Now ptrdiff_t.
1895 (charset_compare): Don't overflow if priorities differ greatly.
1896 (Fsort_charsets): Don't assume list length fits in int.
1897 Check for size-calculation overflow when allocating sort data.
1898 (syms_of_charset): Allocate an initial charset table that is
1899 just under 64 KiB, to avoid problems with glibc malloc and mmap.
1900
1901 * cmds.c (internal_self_insert): Check for size-calculation overflow.
1902
1903 * composite.h (struct composition.glyph_len): Now int, not unsigned.
1904 The actual value is always <= INT_MAX, and leaving it unsigned made
1905 overflow checking harder.
1906
1907 * dispextern.h (struct glyph_matrix.rows_allocated)
1908 (struct face_cache.size): Now ptrdiff_t, for convenience in use
1909 with xpalloc. The values are still always <= INT_MAX.
1910
1911 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
1912
1913 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
1914 (SAFE_NALLOCA): New macro.
1915
1916 * region-cache.c (struct boundary.pos, find_cache_boundary)
1917 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
1918 (set_cache_region, invalidate_region_cache)
1919 (revalidate_region_cache, know_region_cache, region_cache_forward)
1920 (region_cache_backward, pp_cache):
1921 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
1922 so that ptrdiff_t * can be passed to xpalloc.
1923 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
1924 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
1925 (pp_cache): Don't assume cache_len fits in int.
1926 * region-cache.h: Adjust extern decls to match.
1927
1928 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
1929 EMACS_INT, since either will do, for xpalloc.
1930
1931 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
1932 (xnmalloc, xnrealloc, xpalloc): New functions.
1933
1934 * bidi.c (bidi_shelve_header_size): New constant.
1935 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
1936 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
1937
1938 * bidi.c (bidi_cache_shrink):
1939 * buffer.c (overlays_at, overlays_in, record_overlay_string)
1940 (overlay_strings):
1941 Don't update size of array until after memory allocation succeeds,
1942 because xmalloc/xrealloc may not return.
1943 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
1944 now that we have proper integer overflow checking.
1945 (record_overlay_string, overlay_strings): Catch overflows when
1946 calculating size of overlay_str_buf.
1947
1948 * callproc.c (Fcall_process): Check for size overflow when
1949 calculating size of args2.
1950 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
1951 Normally we prefer signed values, but sticking with ptrdiff_t would
1952 require adding more-complicated checks.
1953
1954 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
1955 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
1956 Redo buffer-overflow calculations to avoid integer overflow.
1957 Add a FIXME comment where memory seems to be over-allocated.
1958
1959 * character.c (Fstring): Check for size-calculation overflow.
1960
1961 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
1962 unnecessary integer overflow. Check for size overflow.
1963 (encode_coding_object): Don't update size until xmalloc succeeds.
1964
1965 * composite.c (get_composition_id): Check for overflow in glyph
1966 length calculations.
1967
1968 Integer and memory overflow fixes for display code.
1969 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
1970 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
1971 (scrolling_window): Check for overflow in size calculations.
1972 (line_draw_cost, realloc_glyph_pool, add_row_entry):
1973 Don't assume glyph table len fits in int.

1975 (row_table_size): Now ptrdiff_t, not int.
1976 (scrolling_window): Avoid overflow in size calculations.
1977 Don't update size until allocation succeeds.
1978 * fns.c (concat): Check for overflow in size calculations.
1979 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
1980 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
1981 (NEXT_ALMOST_PRIME_LIMIT): New constant.
1982
1983 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
1984 (get_doc_string): Check for size calculation overflow.
1985 Don't update size until allocation succeeds.
1986 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
1987 EMACS_INT, where ptrdiff_t will do.
1988 (Fsubstitute_command_keys): Check for string overflow.
1989
1990 * editfns.c (set_time_zone_rule): Don't assume environment length
1991 fits in int.
1992 (message_length): Now ptrdiff_t, not int.
1993 (Fmessage_box): Don't update size until allocation succeeds.
1994 Don't assume message length fits in int.
1995 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
1996
1997 * emacs.c (main): Do not reallocate argv, since there is a null at
1998 the end that can be overwritten, and this way there's no need to
1999 worry about size-calculation overflow.
2000 (sort_args): Check for size-calculation overflow.
2001
2002 * eval.c (init_eval_once, grow_specpdl): Don't update size until
2003 alloc succeeds.
2004 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
2005
2006 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
2007 (x_set_scroll_bar_width, x_figure_window_size):
2008 Check for integer overflow.
2009 (x_set_alpha): Do not assume XINT fits in int.
2010
2011 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
2012 This is for the members text_lines, text_cols, total_lines, total_cols,
2013 where the system imposes an 'int' limit.
2014
2015 * fringe.c (Fdefine_fringe_bitmap):
2016 Don't update size until alloc works.
2017
2018 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
2019 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
2020
2021 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
2022 Check for size-calculation overflow.
2023 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
2024 do, as we prefer signed integers.
2025 (id_to_widget.max_size, id_to_widget.used)
2026 (xg_store_widget_in_map, xg_remove_widget_from_map)
2027 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
2028 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
2029 Use and return ptrdiff_t, not int.
2030 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
2031 * gtkutil.h: Change prototypes to match the above.
2032
2033 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
2034 are duplicate now that they've been promoted to lisp.h.
2035 (x_allocate_bitmap_record, x_alloc_image_color)
2036 (make_image_cache, cache_image, xpm_load):
2037 Don't update size until alloc is done.
2038 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
2039 (x_detect_edges):
2040 Check for size calculation overflow.
2041 (ct_colors_allocated_max): New constant.
2042 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
2043 overflow.
2044
2045 * keyboard.c (read_char, menu_bar_items, tool_bar_items)
2046 (read_char_x_menu_prompt, read_char_minibuf_menu_width)
2047 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
2048 Use ptrdiff_t, not int, to count maps.
2049 (read_char_minibuf_menu_prompt): Check for overflow in size
2050 calculations. Don't update size until allocation succeeds.
2051 Redo calculations to avoid overflow.
2052 * keyboard.h: Change prototypes to match the above.
2053
2054 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
2055 to count maps.

2078 (Fset_match_data): Don't assume list lengths fit in 'int'.
2079
2080 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
2081 for command line length. Do not attempt to address one before the
2082 beginning of an array, as that's not portable.
2083
2084 * term.c (max_frame_lines): Remove; unused.
2085 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
2086 not int.
2087 (encode_terminal_code, calculate_costs): Check for size
2088 calculation overflow.
2089 (encode_terminal_code): Use ptrdiff_t, not int, to record glyph

2093
2094 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
2095 subtracting pointers.

2097 until alloc done.
2098
2099 * tparam.c (tparam1): Use ptrdiff_t, not int, for sizes.
2100 Don't update size until alloc done.
2101 Redo size calculations to avoid overflow.
2102 Check for size calculation overflow.
2103 (main) [DEBUG]: Fix typo in invoking tparam1.
2104
2105 * xdisp.c (store_mode_line_noprop_char, x_consider_frame_title):
2106 Use ptrdiff_t, not int, for sizes.

2111 (Finternal_make_lisp_face, cache_face):
2112 Check for size calculation overflow.
2113 (cache_face): Treat size calculation overflows as if they were
2114 memory exhaustion (the usual treatment), rather than aborting.
2115
2116 * xfns.c (x_encode_text, x_set_name_internal)
2117 (Fx_change_window_property): Use ptrdiff_t, not int, to count

2122 (xg_select): Check for size calculation overflow.
2123 Don't update size until alloc done.
2124
2125 * xrdb.c (get_environ_db): Don't assume path length fits in int,
2126 as sprintf is limited to int lengths.
2127
2128 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
2129 (X_LONG_MIN): New macros.
2130 Use them to make the following changes clearer.
2131 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
2132 This change doesn't affect the value now, but it may help remind
2133 future maintainers not to raise the value too much later.
2134 (SELECTION_QUANTUM): Remove, replacing with ...
2135 (selection_quantum): ... new function, which avoids overflow.
2136 All uses changed.
2137 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
2138 assumption that selection length fits in 'int'.
2139 (x_reply_selection_request, x_handle_selection_request)
2140 (x_get_window_property, receive_incremental_selection)
2141 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
2142 (lisp_data_to_selection_data, clean_local_selection_data):
2143 Use ptrdiff_t, not int, to record length of selection.
2144 (x_reply_selection_request, x_get_window_property)
2145 (receive_incremental_selection, x_property_data_to_lisp):
2146 Redo calculations to avoid overflow.
2147 (x_reply_selection_request): When sending hint, ceiling it at
2148 X_LONG_MAX rather than relying on wraparound overflow to send
2149 something.
2150 (x_get_window_property, receive_incremental_selection)
2151 (lisp_data_to_selection_data, x_property_data_to_lisp):
2152 Check for size-calculation overflow.
2153 (x_get_window_property, receive_incremental_selection)
2154 (lisp_data_to_selection_data, Fx_register_dnd_atom):
2155 Don't store size until memory allocation succeeds.
2156 (x_get_window_property): Plug memory leak on memory exhaustion.
2157 Don't double-block input; malloc is safe here. Don't assume 2**34
2158 - 4 fits in unsigned long. Add an xassert to check
2159 XGetWindowProperty overflow. Be more careful about overflow
2160 calculations, and distinguish size from memory overflow better.
2161 (receive_incremental_selection): When tracing, don't assume
2162 unsigned int is less than INT_MAX.
2163 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
2164 harmful) conversions of unsigned short to int.
2165 (lisp_data_to_selection_data): Don't assume that integers
2166 in the range -65535 through -1 fit in an X unsigned short.
2167 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
2168 result parameters unless successful. Rely on cons_to_unsigned
2169 to report problems with elements; the old code wasn't right anyway.
2170 (x_check_property_data): Check for int overflow; we cannot use
2171 a wider type due to X limits.
2172 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.

2177 (x_term_init): Check for size calculation overflow.
2178 (x_color_cells): Don't store size until memory allocation succeeds.
2179 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
2180 Don't assume alloca size is less than MAX_ALLOCA.
2181 (x_term_init): Don't assume length fits in int (sprintf is limited
2182 to int size).
2183
2184 Use ptrdiff_t for composition IDs.
2185 * character.c (lisp_string_width):
2186 * composite.c (composition_table_size, n_compositions)
2187 (get_composition_id, composition_gstring_from_id):

2204 * lisp.h (hash_lookup, hash_put):
2205 * minibuf.c (Ftest_completion):
2206 Use ptrdiff_t for hash table indexes, not int (which is too
2207 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
2208 32-bit --with-wide-int hosts).
2209
2210 * charset.c (Fdefine_charset_internal): Check for integer overflow.
2211 Add a FIXME comment about memory leaks.
2212 (syms_of_charset): Don't assume xmalloc returns.
2213
2214 Don't assume that stated character widths fit in int.
2215 * character.c (Fchar_width, c_string_width, lisp_string_width):
2216 * character.h (CHAR_WIDTH):
2217 * indent.c (MULTIBYTE_BYTES_WIDTH):
2218 Use sanitize_char_width to avoid undefined and/or bad behavior
2219 with outlandish widths.
2220 * character.h (sanitize_tab_width): Rename from sanitize_width,
2221 now that we have two such functions. All uses changed.
2222 (sanitize_char_width): New inline function.
2223

2232 * fileio.c: Integer overflow issues with file modes.
2233 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
2234
2235 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
2236 Remove unreachable code.
2237 (read_hex, load_charset_map_from_file): Check for integer overflow.
2238
2239 * xterm.c: don't go over XClientMessageEvent limit
2240 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
2241 (x_send_scroll_bar_event): Likewise. Check that the size does not
2242 exceed limits imposed by XClientMessageEvent, as well as the usual
2243 ptrdiff_t and size_t limits.
2244
2245 * keyboard.c: Overflow, signedness and related fixes.
2246 (make_lispy_movement): Use same integer type in forward decl
2247 that is used in the definition.
2248 (read_key_sequence, keyremap_step):
2249 Change bufsize argument back to int, undoing my 2011-03-30 change.
2250 We prefer signed types, and int is wide enough here.
2251 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
2252 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
2253 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
2254 length, not size_t. Use ptrdiff_t for index, not int.
2255 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
2256 possibility of integer overflow.
2257
2258 Overflow, signedness and related fixes for images.

2267 * nsmenu.m (update_frame_tool_bar):
2268 * xdisp.c (calc_pixel_width_or_height):
2269 * xfns.c (image_cache_refcount):
2270 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits

2277 when the callers expect that.
2278 (image_ascent): Redo ascent calculation to avoid int overflow.
2279 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
2280 (lookup_image): Remove unnecessary tests.
2281 (xbm_image_p): Locals are now of int, not EMACS_INT,
2282 since parse_image_check makes sure they fit into int.
2283 (png_load, gif_load, svg_load_image):
2284 Prefer int to unsigned where either will do.
2285 (tiff_handler): New function, combining the cores of the
2286 old tiff_error_handler and tiff_warning_handler.
2287 This function is rewritten to use vsnprintf and thereby avoid
2288 stack buffer overflows. It uses only the features of vsnprintf
2289 that are common to both POSIX and native Microsoft.
2290 (tiff_error_handler, tiff_warning_handler): Use it.
2291 (tiff_load, gif_load, imagemagick_load_image):
2292 Don't assume :index value fits in 'int'.
2293 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
2294 (imagemagick_load_image): Check that crop parameters fit into
2295 the integer types that MagickCropImage accepts. Don't assume
2296 Vimagemagick_render_type has a nonnegative value. Don't assume
2297 size_t fits in 'long'.
2298 (gs_load): Use printmax_t to print the widest integers possible.

2302
2303 * xdisp.c (redisplay_window): Don't force window start if point
2304 will be invisible in the resulting window. (Bug#9324)
2305
2306 2011-08-25 Eli Zaretskii <eliz@gnu.org>
2307
2308 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
2309 the display spec is of the form `(space ...)'.
2310 (handle_display_spec): Return the value returned by
2311 handle_single_display_spec, not just 1 or zero.
2312 (handle_single_display_spec): If the display spec is of the form
2313 `(space ...)', and specifies display in the text area, return 2
2314 rather than 1.
2315 (try_cursor_movement): Check for the need to scroll more
2316 accurately, and prefer exact match for point under bidi.
2317 Don't advance `row' beyond the last row of the window.
2318
2319 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
2320 into disp_prop; all users changed.
2321
2322 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns

2335 buffers, return left-to-right.
2336 (set_cursor_from_row): Consider candidate row a win if its glyph
2337 represents a newline and point is on that newline. Fixes cursor
2338 positioning on the newline at EOL of R2L text within L2R
2339 paragraph, and vice versa.
2340 (try_cursor_movement): Check continued rows, in addition to
2341 continuation rows. Fixes unwarranted scroll when point enters a
2342 continued line of R2L text within an L2R paragraph, or vice versa.
2343 (cursor_row_p): Consider the case of point being equal to
2344 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
2345 from the end of a short line to the beginning of a continued line
2346 of R2L text within L2R paragraph.
2347 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for

2369
2370 * xdisp.c (redisplay_window): When computing centering_position,
2371 account for the height of the header line. (Bug#8874)
2372
2373 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
2374 instead of CHAR_TO_BYTE. Fixes a crash when a completion
2375 candidate is selected by the mouse, and that candidate has a
2376 composed character under the mouse.
2377
2378 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
2379 coordinates reported by pos-visible-in-window-p for a composed
2380 character in column zero.

2387
2388 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
2389 consider it a hit if to_charpos is anywhere in the range of the
2390 composed buffer positions.
2391
2392 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
2393
2394 * image.c (gif_load): Don't assume that each subimage has the same
2395 dimensions as the base image. Handle disposal method that is
2396 "undefined" by the gif spec (Bug#9335).
2397
2398 2011-08-20 Chong Yidong <cyd@stupidchicken.com>

2406 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
2407 from an Org mode buffer to a Speedbar frame.
2408
2409 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
2410 a composition, take its buffer position from IT->cmp_it.charpos.
2411 Fixes cursor positioning at the beginning of a line that begins
2412 with a composed character.
2413
2414 2011-08-18 Eli Zaretskii <eliz@gnu.org>
2415
2416 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
2417 character bidirectional type, use STRONG_L instead. Fixes crashes
2418 in a buffer produced by `describe-categories'.
2419
2420 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
2421 members before the level stack, so they would be saved and
2422 restored when copying iterator state. Fixes incorrect reordering
2423 around TABs covered by display properties.
2424
2425 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>

2511 the event loop. Get status from as_status (Bug#7276).
2512
2513 * nsterm.m (sendEvent): If event is NSApplicationDefined and
2514 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
2515 the event loop (Bug#7276).

2554 when IT->position is set up wrongly due to some bug.
2555 Set IT->current to match the bidi iterator unconditionally.
2556 (push_display_prop): Allow GET_FROM_STRING as IT->method on
2557 entry. Force push_it to save on the stack the current
2558 buffer/string position, to be restored by pop_it. Fix flags in
2559 the iterator structure wrt the object coming from a display
2560 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
2561 properties. (Bug#9284)
2562
2563 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
2564
2565 * fontset.c (fontset_get_font_group): Add proper type checks.

2567
2568 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2569
2570 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
2571 and LC_VERSION_MIN_MACOSX.
2572 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
2573 (dump_it) [LC_FUNCTION_STARTS]: Use it.
2574
2575 2011-08-08 Eli Zaretskii <eliz@gnu.org>
2576
2577 * xdisp.c (forward_to_next_line_start): Allow to use the
2578 no-display-properties-and-no-overlays under bidi display.
2579 Set disp_pos in the bidi iterator to avoid searches for display
2580 properties and overlays.
2581
2582 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
2583
2584 * editfns.c (Fset_time_zone_rule): Document relationship with the
2585 setenv function.
2586
2587 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
2588 the font entity extracted from the cache (Bug#8109).
2589
2590 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
2591
2592 * composite.c (autocmp_chars): Don't reset point. That is done by
2593 restore_point_unwind (Bug#5984).
2594
2595 2011-08-07 Juri Linkov <juri@jurta.org>
2596
2597 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
2598 to show the arg `TIME' instead of `TIMEVAL'.
2599

2601
2602 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
2603 display property strides EOL and includes a newline, as in
2604 longlines-mode. (Bug#9254)
2605 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
2606 word-wrap under bidirectional display. (Bug#9224)
2607
2608 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
2609 is non-zero, even if the data buffer is NULL. Fixes a crash in
2610 vertical-motion with longlines-mode. (Bug#9254)
2611
2612 2011-08-05 Eli Zaretskii <eliz@gnu.org>
2613
2614 * bidi.c <bidi_cache_total_alloc>: Now static.
2615 (bidi_initialize): Initialize bidi_cache_total_alloc.
2616
2617 * xdisp.c (display_line): Release buffer allocated for shelved bidi
2618 cache. (Bug#9221)
2619
2620 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
2621 amount allocated this far in `bidi_cache_total_alloc'.
2622 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
2623 non-zero, only free the data buffer without restoring the cache
2624 contents. All callers changed.
2625
2626 * dispextern.h (bidi_unshelve_cache): Update prototype.
2627
2628 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
2629 (move_it_in_display_line, move_it_to)
2630 (move_it_vertically_backward, move_it_by_lines): Replace the call
2631 to xfree to an equivalent call to bidi_unshelve_cache.
2632 (move_it_in_display_line_to): Fix logic of returning
2633 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
2634
2635 2011-08-05 Eli Zaretskii <eliz@gnu.org>
2636
2637 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
2638 came from a string character with a `cursor' property. (Bug#9229)
2639
2640 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
2641
2642 * Makefile.in (LIB_PTHREAD): New variable.
2643 (LIBES): Add LIB_PTHREAD (Bug#9216).
2644
2645 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
2646 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
2647
2648 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
2649
2650 * regex.c (re_iswctype): Remove some redundant boolean conversions.
2651
2652 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
2653
2654 * xterm.c (x_find_topmost_parent): New function.
2655 (x_set_frame_alpha): Find topmost parent window with
2656 x_find_topmost_parent and set the property there also (bug#9181).
2657 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
2658
2659 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
2660
2661 * callproc.c (Fcall_process): Avoid vfork clobbering
2662 the local vars buffer, coding_systems, current_dir.
2663
2664 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
2665
2666 * keymap.c (Fmake_composed_keymap): Move to subr.el.
2667
2668 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
2669
2670 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
2671 so that it is not optimized away.
2672
2673 * xdisp.c (compute_display_string_pos): Remove unused local.
2674
2675 2011-08-02 Eli Zaretskii <eliz@gnu.org>
2676
2677 Fix slow cursor motion and scrolling in large buffers with
2678 selective display, like Org Mode buffers. (Bug#9218)
2679
2680 * dispextern.h (struct bidi_it): New member disp_prop_p.
2681
2682 * xdisp.c: Remove one-slot cache of display string positions.
2683 (compute_display_string_pos): Accept an additional argument
2684 DISP_PROP_P; callers changed. Scan at most 5K characters forward
2685 for a display string or property. If found, set DISP_PROP_P
2686 non-zero.
2687
2688 * bidi.c (bidi_fetch_char): Accept an additional argument
2689 DISP_PROP_P, and pass it to compute_display_string_pos.
2690 Only handle text covered by a display string if DISP_PROP_P is returned
2691 non-zero. All callers of bidi_fetch_char changed.
2692
2693 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
2694
2695 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
2696
2697 2010-12-03 Don March <don@ohspite.net>
2698
2699 * keymap.c (Fdefine_key): Fix non-prefix key error message when
2700 last character M-[char] is translated to ESC [char] (bug#7541).
2701
2702 2011-08-02 Kenichi Handa <handa@m17n.org>
2703
2704 * lisp.h (uniprop_table): Extern it.
2705
2706 * chartab.c (uniprop_table): Make it non-static.
2707
2708 2011-08-01 Eli Zaretskii <eliz@gnu.org>
2709
2710 * xdisp.c (forward_to_next_line_start): Accept additional argument
2711 BIDI_IT_PREV, and store into it the state of the bidi iterator had
2712 on the newline.
2713 (reseat_at_next_visible_line_start): Use the bidi iterator state
2714 returned by forward_to_next_line_start to restore the state of
2715 it->bidi_it after backing up to previous newline. (Bug#9212)
2716
2717 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
2718
2719 * regex.c (re_comp): Protoize.
2720 (re_exec): Fix return type.
2721 (regexec): Fix type of `ret'. (Bug#9203)
2722
2723 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
2724
2725 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
2726 This is needed if max-image-size is a floating-point number.
2727
2728 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
2729
2730 * print.c (print_object): Print empty symbol as ##.
2731
2732 * lread.c (read1): Read ## as empty symbol.
2733
2734 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
2735
2736 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
2737 setting frame foreground color (Bug#9175).
2738 (x_set_background_color): Likewise.
2739
2740 * nsmenu.m (-setText): Size tooltip dimensions precisely to
2741 contents (Bug#9176).
2742 (EmacsTooltip -init): Remove bezels and add shadows to
2743 tooltip windows.
2744
2745 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
2746 or scroll bar (Bug#8470).
2747
2748 * nsfont.m (nsfont_open): Remove assignment to voffset and
2749 unnecessary vars hshink, expand, hd, full_height, min_height.
2750 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
2751
2752 * nsterm.h (nsfont_info): Remove voffset field.
2753
2754 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
2755
2756 Implement strike-through and overline on NextStep (Bug#8863).
2757
2758 * nsfont.m (nsfont_open): Use underline position provided by font,
2759 instead of hard-coded value of 2.
2760 (nsfont_draw): Call ns_draw_text_decoration instead.
2761
2762 * nsterm.h: Add declaration for ns_draw_text_decoration.
2763
2764 * nsterm.m (ns_draw_text_decoration): New function for drawing
2765 underline, overline, and strike-through.
2766 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
2767 ns_draw_text_decoration. Change treatment of cursor drawing to
2768 accommodate underlining, etc.
2769
2770 2011-07-28 Eli Zaretskii <eliz@gnu.org>
2771
2772 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
2773 default.
2774
2775 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
2776
2777 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
2778 Without this fix, if a signal arrives just after memory fills up,
2779 'malloc' might be invoked reentrantly.
2780
2781 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
2782 In other words, assume that every image size is allowed, on non-X
2783 hosts. This assumption is probably wrong, but it lets Emacs compile.
2784
2785 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
2786
2787 * regex.c (re_iswctype): Convert return values to boolean.
2788
2789 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
2790
2791 * xdisp.c (compute_display_string_pos): Don't use cached display
2792 string position if the buffer had its restriction changed.
2793 (Bug#9184)
2794
2795 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
2796
2797 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
2798
2799 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
2800
2801 Integer signedness and overflow and related fixes. (Bug#9079)
2802
2803 * bidi.c: Integer size and overflow fixes.
2804 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
2805 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
2806 (bidi_cache_find_level_change, bidi_cache_ensure_space)
2807 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
2808 (bidi_find_other_level_edge):
2809 Use ptrdiff_t instead of EMACS_INT where either will do.
2810 This works better on 32-bit hosts configured --with-wide-int.
2811 (bidi_cache_ensure_space): Check for size-calculation overflow.
2812 Use % rather than repeated addition, for better worst-case speed.
2813 Don't set bidi_cache_size until after xrealloc returns, because it
2814 might not return.
2815 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
2816 (bidi_cache_ensure_space): Also check that the bidi cache size
2817 does not exceed that of the largest Lisp string or buffer. See Eli
2818 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
2819
2820 * alloc.c (__malloc_size_t): Remove.
2821 All uses replaced by size_t. See Andreas Schwab's note
2822 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
2823
2824 * image.c: Improve checking for integer overflow.
2825 (check_image_size): Assume that f is nonnull, since
2826 it is always nonnull in practice. This is one less thing to
2827 worry about when checking for integer overflow later.
2828 (x_check_image_size): New function, which checks for integer
2829 overflow issues inside X.
2830 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
2831 This removes the need for a memory_full check.
2832 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
2833 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
2834 (xbm_read_bitmap_data): Change locals back to 'int', since
2835 their values must fit in 'int'.
2836 (xpm_load_image, png_load, tiff_load):
2837 Invoke x_create_x_image_and_pixmap earlier,
2838 to avoid much needless work if the image is too large.
2839 (tiff_load): Treat overly large images as if
2840 x_create_x_image_and_pixmap failed, not as malloc failures.
2841 (gs_load): Use x_check_image_size.
2842
2843 * gtkutil.c: Omit integer casts.
2844 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
2845 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
2846
2847 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
2848
2849 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
2850 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
2851 would wrongly return t on a 64-bit host.
2852
2853 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
2854 The plain *_OVERFLOW macros run afoul of GCC bug 49705
2855 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
2856 and therefore cause GCC to emit a bogus diagnostic in some cases.
2857
2858 * image.c: Integer signedness and overflow and related fixes.
2859 This is not an exhaustive set of fixes, but it's time to
2860 record what I've got.
2861 (lookup_pixel_color, check_image_size): Remove redundant decls.
2862 (check_image_size): Don't assume that arbitrary EMACS_INT values
2863 fit in 'int', or that arbitrary 'double' values fit in 'int'.
2864 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
2865 (tiff_load, imagemagick_load_image):
2866 Check for overflow in size calculations.
2867 (x_create_x_image_and_pixmap): Remove unnecessary test for
2868 xmalloc returning NULL; that can't happen.
2869 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
2870 (xpm_color_bucket): Use better integer hashing function.
2871 (xpm_cache_color): Don't possibly over-allocate memory.
2872 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
2873 (gif_memory_source):
2874 Use ptrdiff_t, not int or size_t, to record sizes.
2875 (png_load): Don't assume values greater than 2**31 fit in 'int'.
2876 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
2877 either works, as we prefer signed integers.
2878 (tiff_read_from_memory, tiff_write_from_memory):
2879 Return tsize_t, not size_t, since that's what the TIFF API wants.
2880 (tiff_read_from_memory): Don't fail simply because the read would
2881 go past EOF; instead, return a short read.
2882 (tiff_load): Omit no-longer-needed casts.
2883 (Fimagemagick_types): Don't assume size fits into 'int'.
2884
2885 Improve hashing quality when configured --with-wide-int.
2886 * fns.c (hash_string): New function, taken from sxhash_string.
2887 Do not discard information about ASCII character case; this
2888 discarding is no longer needed.
2889 (sxhash-string): Use it. Change sig to match it. Caller changed.
2890 * lisp.h: Declare it.
2891 * lread.c (hash_string): Remove, since we now use fns.c's version.
2892 The fns.c version returns a wider integer if --with-wide-int is
2893 specified, so this should help the quality of the hashing a bit.
2894
2895 * emacs.c: Integer overflow minor fix.
2896 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
2897 Define only if GNU_LINUX.
2898 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
2899
2900 * dispnew.c: Integer signedness and overflow fixes.
2901 Remove unnecessary forward decls, that were a maintenance hassle.
2902 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
2903 All uses changed.
2904 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
2905 (scrolling_window): Use ptrdiff_t, not int, for byte count.
2906 (prepare_desired_row, line_draw_cost):
2907 Use int, not unsigned, where either works.
2908 (save_current_matrix, restore_current_matrix):
2909 Use ptrdiff_t, not size_t, where either works.
2910 (init_display): Check for overflow more accurately, and without
2911 relying on undefined behavior.
2912
2913 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
2914 Remove, replacing with the new symbols in lisp.h. All uses changed.
2915 * fileio.c (make_temp_name):
2916 * filelock.c (lock_file_1, lock_file):
2917 * xdisp.c (message_dolog):
2918 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
2919 Use pMd etc. instead.
2920 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
2921 replacing the pWIDE etc. symbols removed from editfns.c.
2922
2923 * keyboard.h (num_input_events): Now uintmax_t.
2924 This is (very slightly) less likely to mess up due to wraparound.
2925 All uses changed.
2926
2927 * buffer.c: Integer signedness fixes.
2928 (alloc_buffer_text, enlarge_buffer_text):
2929 Use ptrdiff_t rather than size_t when either will do, as we prefer
2930 signed integers.
2931
2932 * alloc.c: Integer signedness and overflow fixes.
2933 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
2934 (__malloc_size_t): Default to size_t, not to int.
2935 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
2936 (Fgarbage_collect, mark_object_loop_halt, mark_object):
2937 Prefer ptrdiff_t to size_t when either would do, as we prefer
2938 signed integers.
2939 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
2940 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
2941 Now const. Initialize with values that are in range even if char
2942 is signed.
2943 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
2944 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
2945 These functions do the right thing with sizes > 2**32.
2946 (check_depth): Now ptrdiff_t, not int.
2947 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
2948 Adjust to new way of storing sizes. Check for size overflow bugs
2949 in rest of code.
2950 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
2951 slightly wrong anyway, as it missed one instance of
2952 XMALLOC_OVERRUN_CHECK_OVERHEAD.
2953 (refill_memory_reserve): Omit needless cast to size_t.
2954 (mark_object_loop_halt): Mark as externally visible.
2955
2956 * xselect.c: Integer signedness and overflow fixes.
2957 (Fx_register_dnd_atom, x_handle_dnd_message):
2958 Use ptrdiff_t, not size_t, since we prefer signed.
2959 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
2960 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
2961 x_dnd_atoms_size and x_dnd_atoms_length.
2962
2963 * doprnt.c: Prefer signed to unsigned when either works.
2964 * eval.c (verror):
2965 * doprnt.c (doprnt):
2966 * lisp.h (doprnt):
2967 * xdisp.c (vmessage):
2968 Use ptrdiff_t, not size_t, when using or implementing doprnt,
2969 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
2970 prefer signed arithmetic to avoid comparison confusion.
2971 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
2972 but is a bit tricky.
2973
2974 Assume freestanding C89 headers, string.h, stdlib.h.
2975 * data.c, doprnt.c, floatfns.c, print.c:
2976 Include float.h unconditionally.
2977 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
2978 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
2979 * regex.c: Likewise for stddef.h, string.h.
2980 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
2981 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
2982 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
2983 (STDC_HEADERS): Remove obsolete defines.
2984 * sysdep.c: Include limits.h unconditionally.
2985
2986 Assume support for memcmp, memcpy, memmove, memset.
2987 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
2988 * regex.c (memcmp, memcpy):
2989 Remove; we assume C89 now.
2990
2991 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
2992 (__malloc_safe_bcopy): Remove; no longer needed.
2993
2994 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
2995 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
2996 well either way, and we prefer signed to unsigned.
2997
2998 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
2999
3000 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
3001 closes the connection while we're reading (bug#9182).
3002
3003 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
3004
3005 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
3006 are specified (Bug#9168).
3007
3008 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
3009
3010 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
3011 Found by GCC static checking and --with-wide-int on a 32-bit host.
3012
3013 2011-07-25 Eli Zaretskii <eliz@gnu.org>
3014
3015 * xdisp.c (compute_display_string_pos): Fix logic of caching
3016 previous display string position. Initialize cached_prev_pos to
3017 -1. Fixes slow-down at the beginning of a buffer.
3018
3019 2011-07-24 Eli Zaretskii <eliz@gnu.org>
3020
3021 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
3022 for attrs[LFACE_FONTSET_INDEX].
3023
3024 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
3025
3026 * xml.c (parse_region): Remove unused local
3027 that was recently introduced.
3028
3029 2011-07-23 Eli Zaretskii <eliz@gnu.org>
3030
3031 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
3032 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
3033
3034 * xdisp.c (move_it_in_display_line_to): Record the best matching
3035 position for TO_CHARPOS while scanning the line, and restore it on
3036 exit if none of the characters scanned was an exact match.
3037 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
3038 when exact match is impossible due to invisible text, and the
3039 lines are truncated.
3040
3041 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
3042
3043 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
3044 for OSX >= 10.7.
3045
3046 2011-07-22 Eli Zaretskii <eliz@gnu.org>
3047
3048 Fix a significant slow-down of cursor motion with C-n, C-p,
3049 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
3050 auto-repeat under bidi redisplay in fontified buffers.
3051 * xdisp.c (compute_stop_pos_backwards): New function.
3052 (next_element_from_buffer): Call compute_stop_pos_backwards to
3053 find a suitable prev_stop when we find ourselves before
3054 base_level_stop.
3055 (reseat): Don't look for prev_stop, as that could mean a very long
3056 run.
3057 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
3058 <cached_disp_overlay_modiff>: Cache for last found display string
3059 position.
3060 (compute_display_string_pos): Return the cached position if asked
3061 about the same buffer in the same area of character positions, and
3062 the buffer wasn't changed since the time the display string
3063 position was cached.
3064
3065 2011-07-22 Eli Zaretskii <eliz@gnu.org>
3066
3067 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
3068 is an integer, which is important for empty lines. (Bug#9149)
3069
3070 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
3071
3072 * frame.c (Fmodify_frame_parameters): In tty case, update the
3073 default face if necessary (Bug#4238).
3074
3075 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
3076
3077 * editfns.c (Fstring_to_char): No need to explain what a character
3078 is in the docstring (Bug#6576).
3079
3080 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
3081
3082 * xml.c (parse_region): Make sure we always return a tree.
3083
3084 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
3085
3086 * xml.c (parse_region): If a document contains only comments,
3087 return that, too.
3088
3089 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
3090
3091 * xml.c (make_dom): Return comments, too.
3092
3093 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
3094
3095 Port to OpenBSD.
3096 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
3097 and the surrounding thread.
3098 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
3099 rather than fgets, and retry after EINTR. Otherwise, 'emacs
3100 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
3101 timer goes off.
3102 * s/openbsd.h (BROKEN_SIGIO): Define.
3103 * unexelf.c (unexec) [__OpenBSD__]:
3104 Don't update the .mdebug section of the Alpha COFF symbol table.
3105
3106 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
3107
3108 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
3109 (bug#8460).
3110
3111 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
3112
3113 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
3114 This fixes some race conditions on the permissions of any newly
3115 created file.
3116
3117 * alloc.c (valid_pointer_p): Use pipe, not open.
3118 This fixes some permissions issues when debugging.
3119
3120 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
3121 If fchown fails to set both uid and gid, try to set just gid,
3122 as that is sometimes allowed. Adjust the file's mode to eliminate
3123 setuid or setgid bits that are inappropriate if fchown fails.
3124
3125 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
3126
3127 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
3128 to compare Lisp_Objects.
3129 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
3130 global_gnutls_log_level, don't mistake it for a Lisp_Object.
3131 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
3132
3133 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
3134
3135 * lread.c (read_integer): Unread even EOF character.
3136 (read1): Likewise. Properly record start position of symbol.
3137
3138 * lread.c (read1): Read `#:' as empty uninterned symbol if no
3139 symbol character follows.
3140
3141 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
3142
3143 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
3144 This works around a problem with the previous change to Fcopy_file.
3145 Recent glibc declares fchown with __attribute__((warn_unused_result)),
3146 and without this change, GCC might complain about discarding
3147 fchown's return value.
3148
3149 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
3150
3151 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
3152
3153 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
3154
3155 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
3156
3157 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
3158
3159 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
3160 it's used from the C level.
3161
3162 * process.c: Use the same condition for POLL_FOR_INPUT in both
3163 keyboard.c and process.c (bug#1858).
3164
3165 2011-07-09 Lawrence Mitchell <wence@gmx.li>
3166
3167 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
3168 (Fgnutls_boot): Use it.
3169
3170 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
3171
3172 * doc.c (Fsubstitute_command_keys): Revert last change.
3173
3174 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
3175
3176 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
3177 quotes the next character, and doesn't affect other longer
3178 sequences (bug#8935).
3179
3180 * lread.c (syms_of_lread): Clarify that is isn't only
3181 `eval-buffer' and `eval-defun' that's affected by
3182 `lexical-binding' (bug#8460).
3183
3184 2011-07-15 Eli Zaretskii <eliz@gnu.org>
3185
3186 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
3187 bidi redisplay when a line includes both an image and is truncated.
3188
3189 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
3190
3191 Fix minor problems found by static checking.
3192 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
3193 (elsz): Now a signed constant, not a size_t var. We prefer signed
3194 types to unsigned, to avoid integer comparison confusion. Without
3195 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
3196 "cannot optimize loop, the loop counter may overflow", a symptom
3197 of the confusion.
3198 * indent.c (Fvertical_motion): Mark locals as initialized.
3199 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
3200
3201 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
3202
3203 * search.c (Fre_search_backward): Mention `case-fold-search' in
3204 all the re_search_* functions (bug#8138).
3205
3206 * keyboard.c (Fopen_dribble_file): Document when the file is
3207 closed (bug#8056).
3208
3209 2011-07-14 Eli Zaretskii <eliz@gnu.org>
3210
3211 * bidi.c (bidi_dump_cached_states): Fix format of displaying
3212 bidi_cache_idx.
3213
3214 Support bidi reordering of display and overlay strings.
3215 * xdisp.c (compute_display_string_pos)
3216 (compute_display_string_end): Accept additional argument STRING.
3217 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
3218 (reseat_to_string): Initialize bidi_it->string.s and
3219 bidi_it->string.schars.
3220 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
3221 NULL (avoids a crash in bidi_paragraph_init).
3222 Initialize itb.string.lstring.
3223 (init_iterator): Call bidi_init_it only of a valid
3224 buffer position was specified. Initialize paragraph_embedding to
3225 L2R.
3226 (reseat_to_string): Initialize the bidi iterator.
3227 (display_string): If we need to ignore text properties of
3228 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
3229 original value of -1 will not work with bidi.)
3230 (compute_display_string_pos): First arg is now struct
3231 `text_pos *'; all callers changed. Support display properties on
3232 Lisp strings.
3233 (compute_display_string_end): Support display properties on Lisp
3234 strings.
3235 (init_iterator, reseat_1, reseat_to_string): Initialize the
3236 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
3237 when iterating on a string not from display properties).
3238 (compute_display_string_pos, compute_display_string_end):
3239 Fix calculation of the object to scan. Fixes an error when using
3240 arrow keys.
3241 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
3242 base_level_stop; instead, set base_level_stop to BEGV.
3243 Fixes crashes in vertical-motion.
3244 (next_element_from_buffer): Improve commentary for when
3245 the iterator is before prev_stop.
3246 (init_iterator): Initialize bidi_p from the default value of
3247 bidi-display-reordering, not from buffer-local value. Use the
3248 buffer-local value only if initializing for buffer iteration.
3249 (handle_invisible_prop): Support invisible properties on strings
3250 that are being bidi-reordered.
3251 (set_iterator_to_next): Support bidi reordering of C strings and
3252 Lisp strings.
3253 (next_element_from_string): Support bidi reordering of Lisp
3254 strings.
3255 (handle_stop_backwards): Support Lisp strings as well.
3256 (display_string): Support display of R2L glyph rows.
3257 Use IT_STRING_CHARPOS when displaying from a Lisp string.
3258 (init_iterator): Don't initialize it->bidi_p for strings
3259 here.
3260 (reseat_to_string): Initialize it->bidi_p for strings here.
3261 (next_element_from_string, next_element_from_c_string)
3262 (next_element_from_buffer): Add xassert's for correspondence
3263 between IT's object being iterated and it->bidi_it.string
3264 structure.
3265 (face_before_or_after_it_pos): Support bidi iteration.
3266 (next_element_from_c_string): Handle the case of the first string
3267 character that is not the first one in the visual order.
3268 (get_visually_first_element): New function, refactored from common
3269 parts of next_element_from_buffer, next_element_from_string, and
3270 next_element_from_c_string.
3271 (tool_bar_lines_needed, redisplay_tool_bar)
3272 (display_menu_bar): Force left-to-right direction. Add a FIXME
3273 comment for making that be controlled by a user option.
3274 (push_it, pop_it): Save and restore the state of the
3275 bidi iterator. Save and restore the bidi_p flag.
3276 (pop_it): Iterate out of display property for string iteration as
3277 well.
3278 (iterate_out_of_display_property): Support iteration over strings.
3279 (handle_single_display_spec): Set up it->bidi_it for iteration
3280 over a display string, and call bidi_init_it.
3281 (handle_single_display_spec, next_overlay_string)
3282 (get_overlay_strings_1, push_display_prop): Set up the bidi
3283 iterator for displaying display or overlay strings.
3284 (forward_to_next_line_start): Don't use the shortcut if
3285 bidi-iterating.
3286 (back_to_previous_visible_line_start): If handle_display_prop
3287 pushed the iterator stack, restore the internal state of the bidi
3288 iterator by calling bidi_pop_it same number of times.
3289 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
3290 and we are bidi-iterating, don't decrement the iterator position;
3291 instead, set the first_elt flag in the bidi iterator, to produce
3292 the same effect.
3293 (reseat_1): Remove redundant setting of string_from_display_prop_p.
3294 (push_display_prop): xassert that we are iterating a buffer.
3295 (push_it, pop_it): Save and restore paragraph_embedding member.
3296 (handle_single_display_spec, next_overlay_string)
3297 (get_overlay_strings_1, reseat_1, reseat_to_string)
3298 (push_display_prop): Set up the `unibyte' member of bidi_it.string
3299 correctly. Don't assume unibyte strings are not bidi-reordered.
3300 (compute_display_string_pos)
3301 (compute_display_string_end): Fix handling the case of C string.
3302 (push_it, pop_it): Save and restore from_disp_prop_p.

3305 (get_overlay_strings_1): Reset the from_disp_prop_p flag.
3306 (pop_it): Call iterate_out_of_display_property only if we are
3307 popping after iteration over a string that came from a display
3308 property. Fix a typo in popping stretch info. Add an assertion
3309 for verifying that the iterator position is in sync with the bidi
3310 iterator.
3311 (handle_single_display_spec, get_overlay_strings_1)
3312 (push_display_prop): Fix initialization of paragraph direction for
3313 string when that of the parent object is not yet determined.
3314 (reseat_1): Call bidi_init_it to resync the bidi
3315 iterator with IT's position. (Bug#7616)
3316 (find_row_edges): If ROW->start.pos gives position
3317 smaller than min_pos, use it as ROW->minpos. (Bug#7616)
3318 (handle_stop, back_to_previous_visible_line_start, reseat_1):
3319 Reset the from_disp_prop_p flag.
3320 (SAVE_IT, RESTORE_IT): New macros.
3321 (pos_visible_p, face_before_or_after_it_pos)
3322 (back_to_previous_visible_line_start)
3323 (move_it_in_display_line_to, move_it_in_display_line)
3324 (move_it_to, move_it_vertically_backward, move_it_by_lines)
3325 (try_scrolling, redisplay_window, display_line): Use them when
3326 saving a temporary copy of the iterator and restoring it back.
3327 (back_to_previous_visible_line_start, reseat_1)
3328 (init_iterator): Empty the bidi cache "stack".
3329 (move_it_in_display_line_to): If iterator ended up at
3330 EOL, but we never saw any buffer positions smaller than
3331 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
3332 motion in bidi-reordered lines.
3333 (move_it_in_display_line_to): Record prev_method and prev_pos
3334 immediately before the call to set_iterator_to_next. Fixes cursor
3335 motion in bidi-reordered lines with stretch glyphs and strings
3336 displayed in margins. (Bug#8133) (Bug#8867)
3337 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
3338 TO_CHARPOS.
3339 (pos_visible_p): Support positions in bidi-reordered lines.
3340 Save and restore bidi cache.
3341
3342 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.
3343 (bidi_paragraph_info): Delete unused struct.
3344 (bidi_cache_idx, bidi_cache_last_idx): Declare EMACS_INT.
3345 (bidi_cache_start): New variable.
3346 (bidi_cache_reset): Reset bidi_cache_idx to bidi_cache_start, not
3347 to zero.
3348 (bidi_cache_fetch_state, bidi_cache_search)
3349 (bidi_cache_find_level_change, bidi_cache_iterator_state)
3350 (bidi_cache_find, bidi_peek_at_next_level)
3351 (bidi_level_of_next_char, bidi_find_other_level_edge)
3352 (bidi_move_to_visually_next): Compare cache index with
3353 bidi_cache_start rather than with zero.
3354 (bidi_fetch_char): Accept new argument STRING; all callers
3355 changed. Support iteration over a string. Support strings with
3356 display properties. Support unibyte strings. Fix the type of
3357 `len' according to what STRING_CHAR_AND_LENGTH expects.
3358 (bidi_paragraph_init, bidi_resolve_explicit_1)
3359 (bidi_resolve_explicit, bidi_resolve_weak)
3360 (bidi_level_of_next_char, bidi_move_to_visually_next):
3361 Support iteration over a string.
3362 (bidi_set_sor_type, bidi_resolve_explicit_1)
3363 (bidi_resolve_explicit, bidi_type_of_next_char): ignore_bn_limit
3364 can now be zero (for strings); special values 0 and -1 were
3365 changed to -1 and -2, respectively.
3366 (bidi_char_at_pos): New function.
3367 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak):
3368 Call it instead of FETCH_MULTIBYTE_CHAR.
3369 (bidi_move_to_visually_next): Abort if charpos or bytepos were not
3370 initialized to valid values.
3371 (bidi_init_it): Don't initialize charpos and bytepos with invalid
3372 values.
3373 (bidi_level_of_next_char): Allow the sentinel "position" to pass

3454
3455 * buffer.c (Fget_buffer_create): Initialize inhibit_shrinking.
3456 The old code sometimes used this field without initializing it.
3457
3458 * alloc.c (gc_sweep): Don't read past end of array.
3459 In theory, the old code could also have corrupted Emacs internals,
3460 though it'd be very unlikely.
3461
3462 2011-07-12 Andreas Schwab <schwab@linux-m68k.org>
3463
3464 * character.c (Fcharacterp): Don't advertise optional ignored

3560
3561 2011-07-08 Paul Eggert <eggert@cs.ucla.edu>
3562
3563 Use pthread_sigmask, not sigprocmask (Bug#9010).
3564 sigprocmask is portable only for single-threaded applications, and
3565 Emacs can be multi-threaded when it uses GTK.

3723 (clone_per_buffer_values): Don't assume that

3763
3764 Random fixes. E.g., (random) never returned negative values.
3765 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
3766 subseconds part to the entropy, as that's a bit more random.
3767 Prefer signed to unsigned, since the signedness doesn't matter and
3768 in general we prefer signed. When given a limit, use a
3769 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
3770 latter isn't right if USE_2_TAGS_FOR_INTS.
3771 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
3772 not 0..VALMASK. Don't discard "excess" bits that random () returns.

3781
3782 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
3783
3784 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
3785 This is more efficient than Ffile_directory_p and avoids a minor race.

3917 * eval.c (struct backtrace): Simplify and port the data structure.
3918 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a

4006
4007 * bidi.c (bidi_paragraph_init): Test for ZV_BYTE before calling

4092 (PRINTPREPARE, printchar, strout):
4093 Don't set size unless allocation succeeds.

4110 (read_integer): Radix is now EMACS_INT, not int,
4111 to improve quality of diagnostics for out-of-range radices.
4112 Calculate buffer size correctly for out-of-range radices.
4113 (read1): Check for integer overflow in radices, and in
4114 read-circle numbers.
4115 (read_escape): Avoid int overflow.
4116 (Fload, openp, read_buffer_size, read1)
4117 (substitute_object_recurse, read_vector, read_list, map_obarray):
4118 Use ptrdiff_t, not int, for sizes.

4139
4140 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
4141 The following patches are for when GLYPH_DEBUG && !XASSERT.
4142 * dispextern.h (trace_redisplay_p, dump_glyph_string):
4143 * dispnew.c (flush_stdout):
4144 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
4145 Mark as externally visible.
4146 * dispnew.c (check_window_matrix_pointers): Now static.
4147 * dispnew.c (window_to_frame_vpos):
4148 * xfns.c (unwind_create_frame):
4149 * xterm.c (x_check_font): Remove unused local.
4150 * scroll.c (CHECK_BOUNDS):
4151 * xfaces.c (cache_fache): Rename local to avoid shadowing.
4152 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
4153 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
4154 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
4155 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
4156 Now static.
4157 (debug_method_add): Use va_list and vsprintf rather than relying
4158 on undefined behavior with wrong number of arguments.
4159 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
4160 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
4161 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
4162 since we're not interested in debugging glyphs with old libraries.
4163 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
4164 GCC 4.6.0's static checking.
4165
4166 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
4167

4187 (x_allocate_bitmap_record): Check for size overflow.
4188 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
4189
4190 Use ptrdiff_t, not int, for overlay counts.

4199 (mouse_face_overlay_overlaps, Foverlays_in):
4200 Use ptrdiff_t, not int, for sizes.
4201 (overlays_at, overlays_in): Check for size-calculation overflow.
4202
4203 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
4204
4205 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
4206 (x_session_initialize): Do not assume string length fits in int.
4207
4208 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
4209 This is unlikely, but can occur if DPI is outlandish.
4210
4211 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
4212 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
4213
4214 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
4215 * xrdb.c (magic_file_p, search_magic_path):
4216 Omit last arg SUFFIX; it was always 0. All callers changed.
4217 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
4218
4219 * xfont.c (xfont_match): Avoid need for strlen.
4220
4221 * xfns.c: Don't assume strlen fits in int.
4222 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
4223
4224 * xdisp.c (message_log_check_duplicate): Return intmax_t,
4225 not unsigned long, as we prefer signed integers. All callers changed.
4226 Detect integer overflow in repeat count.
4227 (message_dolog): Don't assume print length fits in 39 bytes.
4228 (display_mode_element): Don't assume strlen fits in int.
4229
4230 * termcap.c: Don't assume sizes fit in int and never overflow.
4231 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
4232 (gobble_line): Check for size-calculation overflow.
4233
4234 * minibuf.c (Fread_buffer):
4235 * lread.c (intern, intern_c_string):
4236 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
4237 Don't assume string length fits in int.
4238
4239 * keyboard.c (parse_tool_bar_item):
4240 * gtkutil.c (style_changed_cb): Avoid need for strlen.
4241
4242 * font.c: Don't assume string length fits in int.
4243 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
4244 Use ptrdiff_t, not int.
4245 (font_intern_prop): Don't assume string length fits in int.
4246 Don't assume integer property fits in fixnum.
4247 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
4248
4249 * filelock.c: Fix some buffer overrun and integer overflow issues.
4250 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
4251 Reformulate so as not to need the command string.
4252 Invoke gzip -cd rather than gunzip, as it's more portable.
4253 (lock_info_type, lock_file_1, lock_file):
4254 Don't assume pid_t and time_t fit in unsigned long.
4255 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
4256 (current_lock_owner): Prefer signed type for sizes.
4257 Use memcpy, not strncpy, where memcpy is what is really wanted.
4258 Don't assume (via atoi) that time_t and pid_t fit in int.
4259 Check for time_t and/or pid_t out of range, e.g., via a network share.
4260 Don't alloca where an auto var works fine.
4261
4262 * fileio.c: Fix some integer overflow issues.
4263 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
4264 Don't assume string length fits in int.
4265 (directory_file_name): Don't assume string length fits in long.
4266 (make_temp_name): Don't assume pid fits in int, or that its print
4267 length is less than 20.
4268
4269 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
4270
4271 * coding.c (make_subsidiaries): Don't assume string length fits in int.
4272
4273 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
4274
4275 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
4276 We prefer signed integers, even for size calculations.
4277
4278 * emacs.c: Don't assume string length fits in 'int'.
4279 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
4280 (main): Don't invoke strlen when not needed.
4281
4282 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
4283 (XD_DEBUG_MESSAGE): Don't waste a byte.
4284
4285 * callproc.c (getenv_internal_1, getenv_internal)
4286 (Fgetenv_internal):
4287 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
4288
4289 * lread.c (invalid_syntax): Omit length argument.
4290 All uses changed. This doesn't fix a bug, but it simplifies the
4291 code away from its former Hollerith-constant appearance, and it's
4292 one less 'int' to worry about when looking at integer-overflow issues.
4293 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
4294
4295 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
4296 This didn't break anything, but it didn't help either.
4297 It's confusing to put a bogus integer in a place where the actual
4298 value does not matter.
4299 (LIST_END_P): Remove unused macro and its bogus comment.
4300 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
4301
4302 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
4303 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
4304 implementation.
4305 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
4306 We prefer signed types, and the value cannot exceed the EMACS_INT
4307 range anyway (because otherwise the length would not be representable).
4308 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
4309 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
4310 This avoids a GCC warning when WIDE_EMACS_INT.
4311
4312 * indent.c (sane_tab_width): New function.
4313 (current_column, scan_for_column, Findent_to, position_indentation)
4314 (compute_motion): Use it. This is just for clarity.
4315 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
4316
4317 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
4318
4319 * lisp.h (lint_assume): New macro.
4320 * composite.c (composition_gstring_put_cache):
4321 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
4322
4323 * editfns.c, insdel.c:
4324 Omit unnecessary forward decls, to simplify future changes.
4325
4326 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
4327
4328 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
4329
4330 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
4331 Use much-faster test for byte-length change.
4332 Don't assume string byte-length fits in 'int'.
4333 Check that character arg fits in 'int'.
4334 (mapcar1): Declare byte as byte, for clarity.
4335
4336 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
4337
4338 * fns.c (concat): Catch string overflow earlier.
4339 Do not rely on integer wraparound.
4340
4341 * dispextern.h (struct it.overlay_strings_charpos)
4342 (struct it.selective): Now EMACS_INT, not int.
4343 * xdisp.c (forward_to_next_line_start)
4344 (back_to_previous_visible_line_start)
4345 (reseat_at_next_visible_line_start, next_element_from_buffer):
4346 Don't arbitrarily truncate the value of 'selective' to int.
4347
4348 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
4349
4350 * composite.c: Don't truncate sizes to 'int'.
4351 (composition_gstring_p, composition_reseat_it)
4352 (composition_adjust_point): Use EMACS_INT, not int.
4353 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
4354 not EMACS_UINT, for indexes.
4355
4356 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
4357
4358 * buffer.c: Include <verify.h>.
4359 (struct sortvec.priority, struct sortstr.priority):
4360 Now EMACS_INT, not int.
4361 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
4362 (struct sortstr.size, record_overlay_string)
4363 (struct sortstrlist.size, struct sortlist.used):
4364 Don't truncate size to int.
4365 (record_overlay_string): Check for size-calculation overflow.
4366 (init_buffer_once): Check at compile-time, not run-time.
4367
4368 2011-06-22 Jim Meyering <meyering@redhat.com>
4369
4370 Don't leak an XBM-image-sized buffer
4371 * image.c (xbm_load): Free the image buffer after using it.
4372
4373 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
4374
4375 Port to Sun C.
4376 * composite.c (find_automatic_composition): Omit needless 'return 0;'
4377 that Sun C diagnosed.
4378 * fns.c (secure_hash): Fix pointer signedness issue.
4379 * intervals.c (static_offset_intervals): New function.
4380 (offset_intervals): Use it.
4381
4382 2011-06-21 Leo Liu <sdl.web@gmail.com>
4383
4384 * deps.mk (fns.o):
4385 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
4386 sha512.h.
4387
4388 * fns.c (secure_hash): Rename from crypto_hash_function and change
4389 the first arg to accept symbols.
4390 (Fsecure_hash): New primitive.
4391 (syms_of_fns): New symbols.
4392
4393 2011-06-20 Deniz Dogan <deniz@dogan.se>
4394
4395 * process.c (Fset_process_buffer): Clarify return value in
4396 docstring.
4397
4398 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
4399
4400 * dispnew.c (add_window_display_history): Use BVAR.
4401
4402 * xdisp.c (debug_method_add): Use BVAR.
4403 (check_window_end, dump_glyph_matrix, dump_glyph)
4404 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
4405
4406 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
4407 Likewise.
4408
4409 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
4410 check till after the cache is created in init_frame_faces.
4411
4412 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
4413
4414 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
4415
4416 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
4417
4418 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
4419 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
4420 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
4421
4422 Improve buffer-overflow checking (Bug#8873).
4423 * fileio.c (Finsert_file_contents):
4424 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
4425 Remove the old (too-loose) buffer overflow checks.
4426 They weren't needed, since make_gap checks for buffer overflow.
4427 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
4428 The old code merely checked for Emacs fixnum overflow, and relied
4429 on undefined (wraparound) behavior. The new code avoids undefined
4430 behavior, and also checks for ptrdiff_t and/or size_t overflow.
4431
4432 * editfns.c (Finsert_char): Don't dump core with very negative counts.
4433 Tune. Don't use wider integers than needed. Don't use alloca.
4434 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
4435
4436 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
4437
4438 * insdel.c, lisp.h (buffer_overflow): New function.
4439 (insert_from_buffer_1, replace_range, replace_range_2):
4440 * insdel.c (make_gap_larger):
4441 * editfns.c (Finsert_char):
4442 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
4443
4444 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
4445
4446 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
4447
4448 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
4449
4450 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
4451 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
4452
4453 * fileio.c: Don't assume EMACS_INT fits in off_t.
4454 (emacs_lseek): New static function.
4455 (Finsert_file_contents, Fwrite_region): Use it.
4456 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
4457
4458 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
4459
4460 * fns.c: Don't overflow int when computing a list length.
4461 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
4462 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
4463 truncation on 64-bit hosts. Check for QUIT every
4464 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
4465 faster and is responsive enough.
4466 (Flength): Report an error instead of overflowing an integer.
4467 (Fsafe_length): Return a float if the value is not representable
4468 as a fixnum. This shouldn't happen except in contrived situations.
4469 (Fnthcdr, Fsort): Don't assume list length fits in int.
4470 (Fcopy_sequence): Don't assume vector length fits in int.
4471
4472 * alloc.c: Check that resized vectors' lengths fit in fixnums.
4473 (header_size, word_size): New constants.
4474 (allocate_vectorlike): Don't check size overflow here.
4475 (allocate_vector): Check it here instead, since this is the only
4476 caller of allocate_vectorlike that could cause overflow.
4477 Check that the new vector's length is representable as a fixnum.
4478
4479 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
4480 The previous code was bogus. For example, next_almost_prime (32)
4481 returned 39, which is undesirable as it is a multiple of 3; and
4482 next_almost_prime (24) returned 25, which is a multiple of 5 so
4483 why was the code bothering to check for multiples of 7?
4484
4485 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
4486
4487 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
4488
4489 Variadic C functions now count arguments with ptrdiff_t.
4490 This partly undoes my 2011-03-30 change, which replaced int with size_t.
4491 Back then I didn't know that the Emacs coding style prefers signed int.
4492 Also, in the meantime I found a few more instances where arguments
4493 were being counted with int, which may truncate counts on 64-bit
4494 machines, or EMACS_INT, which may be unnecessarily wide.
4495 * lisp.h (struct Lisp_Subr.function.aMANY)
4496 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
4497 Arg counts are now ptrdiff_t, not size_t.
4498 All variadic functions and their callers changed accordingly.
4499 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
4500 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
4501 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
4502 * callint.c (Fcall_interactively): Check arg count for overflow,
4503 to avoid potential buffer overrun. Use signed char, not 'int',
4504 for 'varies' array, so that we needn't bother to check its size
4505 calculation for overflow.
4506 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
4507 * eval.c (apply_lambda):
4508 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
4509 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
4510 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
4511
4512 * callint.c (Fcall_interactively): Don't use index var as event count.
4513
4514 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
4515 * mem-limits.h (SIZE): Remove; no longer used.
4516
4517 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
4518
4519 Remove unnecessary casts.
4520 * xterm.c (x_term_init):
4521 * xfns.c (x_set_border_pixel):
4522 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
4523 These aren't needed now that we assume ANSI C.
4524
4525 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
4526 It's more likely to cause problems (due to unsigned overflow)
4527 than to cure them.
4528
4529 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
4530
4531 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
4532
4533 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
4534
4535 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
4536
4537 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
4538
4539 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
4540
4541 GLYPH_CODE_FACE returns EMACS_INT, not int.
4542 * dispextern.h (merge_faces):
4543 * xfaces.c (merge_faces):
4544 * xdisp.c (get_next_display_element, next_element_from_display_vector):
4545 Don't assume EMACS_INT fits in int.
4546
4547 * character.h (CHAR_VALID_P): Remove unused parameter.
4548 * fontset.c, lisp.h, xdisp.c: All uses changed.
4549
4550 * editfns.c (Ftranslate_region_internal): Omit redundant test.
4551
4552 * fns.c (concat): Minor tuning based on overflow analysis.
4553 This doesn't fix any bugs. Use int to hold character, instead
4554 of constantly refetching from Emacs object. Use XFASTINT, not
4555 XINT, for value known to be a character. Don't bother comparing
4556 a single byte to 0400, as it's always less.
4557
4558 * floatfns.c (Fexpt):
4559 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
4560
4561 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
4562 for characters.
4563
4564 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
4565
4566 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
4567 Without this fix, on a 64-bit host (aset S 0 4294967386) would
4568 incorrectly succeed when S was a string, because 4294967386 was
4569 truncated before it was used.
4570
4571 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
4572 Otherwise, an out-of-range integer could cause undefined behavior
4573 on a 64-bit host.
4574
4575 * composite.c: Use int, not EMACS_INT, for characters.
4576 (fill_gstring_body, composition_compute_stop_pos): Use int, not
4577 EMACS_INT, for values that are known to be in character range.
4578 This doesn't fix any bugs but is the usual style inside Emacs and
4579 may generate better code on 32-bit machines.
4580
4581 Make sure a 64-bit char is never passed to ENCODE_CHAR.
4582 This is for reasons similar to the recent CHAR_STRING fix.
4583 * charset.c (Fencode_char): Check that character arg is actually
4584 a character. Pass an int to ENCODE_CHAR.
4585 * charset.h (ENCODE_CHAR): Verify that the character argument is no
4586 wider than 'int', as a compile-time check to prevent future regressions
4587 in this area.
4588
4589 * character.c (char_string): Remove unnecessary casts.
4590
4591 Make sure a 64-bit char is never passed to CHAR_STRING.
4592 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
4593 by silently ignoring the top 32 bits, allowing some values
4594 that were far too large to be valid characters.
4595 * character.h: Include <verify.h>.
4596 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
4597 arguments are no wider than unsigned, as a compile-time check
4598 to prevent future regressions in this area.
4599 * data.c (Faset):
4600 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
4601 (Fsubst_char_in_region):
4602 * fns.c (concat):
4603 * xdisp.c (decode_mode_spec_coding):
4604 Adjust to CHAR_STRING's new requirement.
4605 * editfns.c (Finsert_char, Fsubst_char_in_region):
4606 * fns.c (concat): Check that character args are actually
4607 characters. Without this test, these functions did the wrong
4608 thing with wildly out-of-range values on 64-bit hosts.
4609
4610 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
4611 These casts should not be needed on 32-bit hosts, either.
4612 * keyboard.c (read_char):
4613 * lread.c (Fload): Remove casts to unsigned.
4614
4615 * lisp.h (UNSIGNED_CMP): New macro.
4616 This fixes comparison bugs on 64-bit hosts.
4617 (ASCII_CHAR_P): Use it.
4618 * casefiddle.c (casify_object):
4619 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
4620 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
4621 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
4622 * dispextern.h (FACE_FROM_ID):
4623 * keyboard.c (read_char): Use UNSIGNED_CMP.
4624
4625 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
4626 not to EMACS_INT, to avoid GCC warning.
4627
4628 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
4629
4630 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
4631 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
4632 isn't needed on 32-bit machines.
4633
4634 * buffer.c (Fgenerate_new_buffer_name):
4635 Use EMACS_INT for count, not int.

4662 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
4663 These were 'int' variables that could overflow on 64-bit hosts;
4664 they were never used, so remove them instead of repairing them.

4673 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
4674 when a (possibly-narrower) signed value would do just as well.
4675 We prefer using signed arithmetic, to avoid comparison confusion.
4676
4677 * alloc.c: Catch some string size overflows that we were missing.
4678 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
4679 for convenience in STRING_BYTES_MAX.
4680 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
4681 The definition here is exact; the one in lisp.h was approximate.
4682 (allocate_string_data): Check for string overflow. This catches
4683 some instances we weren't catching before. Also, it catches
4684 size_t overflow on (unusual) hosts where SIZE_MAX <= min
4685 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
4686 and ptrdiff_t and EMACS_INT are both 64 bits.
4687
4688 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
4689 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
4690 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
4691

5197 (LARGE_REQUEST): New macro, so that the issue of large requests
5198 is separated from the issue of spare memory.
5199
5200 2011-06-05 Andreas Schwab <schwab@linux-m68k.org>
5201

5255 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
5256 (bidi_level_of_next_char, bidi_move_to_visually_next):
5257 Support character positions inside a run of characters covered by a
5258 display string.
5259 (bidi_paragraph_init, bidi_resolve_explicit_1)
5260 (bidi_level_of_next_char): Call bidi_fetch_char and
5261 bidi_fetch_char_advance instead of FETCH_CHAR and

5264 (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
5265 definitions.

5267 instead of using explicit *_CHAR codes.
5268 (bidi_resolve_explicit, bidi_resolve_weak):
5269 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
5270 bidirectional text is supported only in multibyte buffers.
5271 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
5272 it to initialize the frame_window_p member of struct bidi_it.

5279 were just reseat()'ed to a new position.
5280
5281 * xdisp.c (set_cursor_from_row): Set start and stop points
5282 according to the row's direction when priming the loop that looks
5283 for the glyph on which to display cursor.
5284 (single_display_spec_intangible_p): Function deleted.
5285 (display_prop_intangible_p): Reimplement to call
5286 handle_display_spec instead of single_display_spec_intangible_p.
5287 Accept 3 additional arguments needed by handle_display_spec.
5288 This fixes incorrect cursor motion across display property with complex
5289 values: lists, `(when COND...)' forms, etc.
5290 (single_display_spec_string_p): Support property values that are
5291 lists with the argument STRING its top-level element.
5292 (display_prop_string_p): Fix the condition for processing a
5293 property that is a list to be consistent with handle_display_spec.
5294 (handle_display_spec): New function, refactored from the
5295 last portion of handle_display_prop.
5296 (compute_display_string_pos): Accept additional argument
5297 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
5298 value of a `display' property is a "replacing spec".
5299 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
5300 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
5301 the display property, but just return a value indicating whether
5302 the display property will replace the characters it covers.
5303 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
5304 frame_window_p members of struct bidi_it.
5305 (compute_display_string_pos, compute_display_string_end):
5306 New functions.

5312 display_prop_intangible_p to its new signature.
5313
5314 * dispextern.h (struct bidi_it): New member frame_window_p.
5315 (bidi_init_it): Update prototypes.
5316 (display_prop_intangible_p): Update prototype.

5328 All callers changed. (Bug#8762)
5329
5330 * gnutls.c: Use Emacs's memory allocators.
5331 Without this change, the gnutls library would invoke malloc etc.
5332 directly, which causes problems on non-SYNC_INPUT hosts, and which
5333 runs afoul of improving memory_full behavior. (Bug#8761)
5334 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
5335 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
5336 xfree instead of the default malloc, realloc, free.
5337 (Fgnutls_boot): No need to check for memory allocation failure,
5338 since xmalloc does that for us.
5339

5357 (xpm_put_color_table_h):
5358 * lisp.h (struct Lisp_Hash_Table):
5359 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
5360 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
5361 for hashes and hash indexes, instead of 'unsigned' and 'int'.
5362 * alloc.c (allocate_vectorlike):
5363 Check for overflow in vector size calculations.
5364 * ccl.c (ccl_driver):
5365 Check for overflow when converting EMACS_INT to int.
5366 * fns.c, image.c: Remove unnecessary static decls that would otherwise
5367 need to be updated by these changes.
5368 * fns.c (make_hash_table, maybe_resize_hash_table):
5369 Check for integer overflow with large hash tables.
5370 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
5371 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
5372 (SXHASH_REDUCE): New macro.
5373 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
5374 Use it instead of discarding useful hash info with large hash values.
5375 (sxhash_float): New function.
5376 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
5377 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
5378 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
5379 Rewrite to use FIXNUM_BITS, as this simplifies things.
5380 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
5381 Adjust signatures to match updated version of code.
5382 (consing_since_gc): Now EMACS_INT, since a single hash table can
5383 use more than INT_MAX bytes.
5384

5431
5432 Make it possible to run ./temacs.
5433
5434 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
5435 syms_of_callproc does the same thing. Remove test for

5448 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
5449
5450 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
5451 (CCL_CODE_MIN): New macro.
5452
5453 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
5454
5455 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
5456
5457 * eval.c (Qdebug): Now static.
5458 * lisp.h (Qdebug): Remove decl. This reverts a part of the
5459 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
5460 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
5461
5462 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
5463
5464 * image.c: Various fixes to ImageMagick code comments.
5465 (Fimagemagick_types): Doc fix.
5466
5467 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
5468
5469 Minor fixes prompted by GCC 4.6.0 warnings.
5470
5471 * xselect.c (converted_selections, conversion_fail_tag): Now static.
5472
5473 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
5474 (x_clipboard_manager_save_all): Move extern decl to ...
5475 * xterm.h: ... here, so that it can be checked for consistency.
5476
5477 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
5478
5479 * xselect.c (x_clipboard_manager_save_frame)
5480 (x_clipboard_manager_save_all): New functions.
5481 (Fx_clipboard_manager_save): Lisp function deleted.
5482
5483 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
5484 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
5485
5486 * xterm.h: Update prototype.
5487
5488 2011-05-28 William Xu <william.xwl@gmail.com>
5489
5490 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
5491 exiting (Bug#8239).
5492
5493 2011-05-28 Jim Meyering <meyering@redhat.com>
5494
5495 Avoid a sign-extension bug in crypto_hash_function.
5496 * fns.c (to_uchar): Define.
5497 (crypto_hash_function): Use it to convert some newly-signed
5498 variables to unsigned, to avoid sign-extension bugs. For example,
5499 without this change, (md5 "truc") would evaluate to
5500 45723a2aff78ff4fff7fff1114760e62 rather than the expected
5501 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
5502 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
5503
5504 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
5505
5506 Integer overflow fixes.
5507
5508 * dbusbind.c: Serial number integer overflow fixes.
5509 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
5510 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
5511 to hold a serial number that is too large for a fixnum.
5512 (Fdbus_method_return_internal, Fdbus_method_error_internal):
5513 Check for serial numbers out of range. Decode any serial number
5514 that was so large that it became a float. (Bug#8722)
5515
5516 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
5517 (Fdbus_call_method, Fdbus_call_method_asynchronously):
5518 Use XFASTINT rather than XUINT when numbers are nonnegative.
5519 (xd_append_arg, Fdbus_method_return_internal):
5520 (Fdbus_method_error_internal): Likewise. Also, for unsigned
5521 arguments, check that Lisp number is nonnegative, rather than
5522 silently wrapping negative numbers around. (Bug#8722)
5523 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
5524 (Bug#8722)
5525
5526 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
5527
5528 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
5529
5530 ccl: add integer overflow checks
5531 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
5532 (IN_INT_RANGE): New macros.
5533 (ccl_driver): Use them to check for integer overflow when
5534 decoding a CCL program. Many of the new checks are whether XINT (x)
5535 fits in int; it doesn't always, on 64-bit hosts. The new version
5536 doesn't catch all possible integer overflows, but it's an
5537 improvement. (Bug#8719)
5538
5539 * alloc.c (make_event_array): Use XINT, not XUINT.
5540 There's no need for unsigned here.
5541
5542 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
5543 This follows up to the 2011-05-06 change that substituted uintptr_t
5544 for EMACS_INT. This case wasn't caught back then.
5545
5546 Rework Fformat to avoid integer overflow issues.
5547 * editfns.c: Include <float.h> unconditionally, as it's everywhere
5548 now (part of C89). Include <verify.h>.
5549 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
5550 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
5551 (Fformat): Avoid the prepass trying to compute sizes; it was only
5552 approximate and thus did not catch overflow reliably. Instead, walk
5553 through the format just once, formatting and computing sizes as we go,
5554 checking for integer overflow at every step, and allocating a larger
5555 buffer as needed. Keep track separately whether the format is
5556 multibyte. Keep only the most-recently calculated precision, rather
5557 than them all. Record whether each argument has been converted to
5558 string. Use EMACS_INT, not int, for byte and char and arg counts.
5559 Support field widths and precisions larger than INT_MAX. Avoid
5560 sprintf's undefined behavior with conversion specifications such as %#d
5561 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
5562 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
5563 formatting out-of-range floating point numbers with int
5564 formats. (Bug#8668)
5565
5566 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
5567
5568 * data.c: Avoid integer truncation in expressions involving floats.
5569 * data.c: Include <intprops.h>.
5570 (arith_driver): When there's an integer overflow in an expression
5571 involving floating point, convert the integers to floating point
5572 so that the resulting value does not suffer from catastrophic
5573 integer truncation. For example, on a 64-bit host (* 4
5574 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
5575 Do not rely on undefined behavior after integer overflow.
5576
5577 merge count_size_as_multibyte, parse_str_to_multibyte
5578 * character.c, character.h (count_size_as_multibyte):
5579 Rename from parse_str_to_multibyte; all uses changed.
5580 Check for integer overflow.
5581 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
5582 since it's now a duplicate of the other. This is more of
5583 a character than a buffer op, so better that it's in character.c.
5584 * fns.c, print.c: Adjust to above changes.
5585
5586 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
5587
5588 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
5589
5590 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
5591
5592 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
5593 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
5594 (x_clipboard_manager_save): Now static.
5595 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
5596
5597 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
5598 (crypto_hash_function): Now static.
5599 Fix pointer signedness problems. Avoid unnecessary initializations.
5600
5601 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
5602
5603 * termhooks.h (Vselection_alist): Make it terminal-local.
5604
5605 * terminal.c (create_terminal): Initialize it.
5606
5607 * xselect.c: Support for clipboard managers.
5608 (Vselection_alist): Move to termhooks.h as terminal-local var.
5609 (LOCAL_SELECTION): New macro.
5610 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
5611 (symbol_to_x_atom): Remove gratuitous arg.
5612 (x_handle_selection_request, lisp_data_to_selection_data)
5613 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
5614 (x_own_selection, x_get_local_selection, x_convert_selection):
5615 New arg, specifying work frame. Use terminal-local Vselection_alist.
5616 (some_frame_on_display): Delete unused function.
5617 (Fx_own_selection_internal, Fx_get_selection_internal)
5618 (Fx_disown_selection_internal, Fx_selection_owner_p)
5619 (Fx_selection_exists_p): New optional frame arg.
5620 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
5621 (x_handle_selection_clear): Don't treat other terminals with the
5622 same keyboard specially. Use the terminal-local Vselection_alist.
5623 (x_clear_frame_selections): Use Frun_hook_with_args.
5624
5625 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
5626
5627 * xterm.h: Add support for those atoms.
5628
5629 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
5630
5631 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
5632 (converted_selections, conversion_fail_tag): New global variables.
5633 (x_selection_request_lisp_error): Free the above.
5634 (x_get_local_selection): Remove unnecessary code.
5635 (x_reply_selection_request): Args changed; handle arbitrary array
5636 of converted selections stored in converted_selections.
5637 Separate the XChangeProperty and SelectionNotify steps.
5638 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
5639 (x_convert_selection): New function.
5640 (x_handle_selection_event): Simplify.
5641 (x_get_foreign_selection): Don't ignore incoming requests while
5642 waiting for an answer; this will fail when we implement
5643 SAVE_TARGETS, and seems unnecessary anyway.
5644 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
5645 (Vx_sent_selection_functions): Doc fix.
5646
5647 2011-05-26 Leo Liu <sdl.web@gmail.com>
5648
5649 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
5650
5651 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5652
5653 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
5654
5655 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
5656 for fringe update if it has periodic bitmap.
5657 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
5658 and fringe_bitmap_periodic_p.
5659
5660 * fringe.c (get_fringe_bitmap_data): New function.
5661 (draw_fringe_bitmap_1, update_window_fringes): Use it.
5662 (update_window_fringes): Record periodicity of fringe bitmap in glyph
5663 row. Mark glyph row for fringe update if periodicity changed.
5664
5665 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
5666 for fringe update unless it has periodic bitmap.
5667
5668 2011-05-25 Kenichi Handa <handa@m17n.org>
5669
5670 * xdisp.c (get_next_display_element): Set correct it->face_id for
5671 a static composition.
5672
5673 2011-05-24 Leo Liu <sdl.web@gmail.com>
5674
5675 * deps.mk (fns.o):
5676 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
5677
5678 * fns.c (crypto_hash_function, Fsha1): New function.
5679 (Fmd5): Use crypto_hash_function.
5680 (syms_of_fns): Add Ssha1.
5681
5682 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
5683
5684 * gnutls.c: Remove unused macros.
5685 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
5686 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
5687 Remove macros that are defined and never used.
5688 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
5689
5690 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
5691
5692 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
5693 (Fx_get_selection_internal): Minor cleanup.
5694 (Fx_own_selection_internal): Rename arguments for consistency with
5695 select.el.
5696
5697 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
5698
5699 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
5700
5701 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
5702
5703 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
5704
5705 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5706
5707 * dispnew.c (scrolling_window): Don't exclude the case that the
5708 last enabled row in the desired matrix touches the bottom boundary.
5709
5710 2011-05-21 Glenn Morris <rgm@gnu.org>
5711
5712 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
5713 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
5714 and add some more files.
5715
5716 2011-05-20 Eli Zaretskii <eliz@gnu.org>
5717
5718 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
5719 report_file_error introduced by the change from 2011-05-07.
5720
5721 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
5722
5723 * systime.h (Time): Define only if emacs is defined.
5724 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
5725 where the include path doesn't have X11/X.h by default. See
5726 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
5727
5728 2011-05-20 Kenichi Handa <handa@m17n.org>
5729
5730 * composite.c (find_automatic_composition): Fix previous change.
5731
5732 2011-05-20 Glenn Morris <rgm@gnu.org>
5733
5734 * lisp.mk: New file, split from Makefile.in.
5735 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
5736 (shortlisp): Remove.
5737 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
5738
5739 2011-05-19 Glenn Morris <rgm@gnu.org>
5740
5741 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
5742 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
5743 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
5744 (lisp): Set the order to that of loadup.el.
5745 (shortlisp): Make it a copy of $lisp.
5746 (SOME_MACHINE_LISP): Remove.
5747 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
5748 Use just $shortlisp, not $SOME_MACHINE_LISP too.
5749
5750 2011-05-18 Kenichi Handa <handa@m17n.org>
5751
5752 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
5753 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
5754 (find_automatic_composition): Mostly rewrite for efficiency.
5755
5756 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
5757
5758 * makefile.w32-in: Update dependencies.
5759
5760 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
5761
5762 * menu.c: Include limits.h (fixes the MS-Windows build broken by
5763 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
5764
5765 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
5766
5767 Fix some integer overflow issues, such as string length overflow.
5768
5769 * insdel.c (count_size_as_multibyte): Check for string overflow.
5770
5771 * character.c (lisp_string_width): Check for string overflow.
5772 Use EMACS_INT, not int, for string indexes and lengths; in
5773 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
5774 the resulting string length overflows an EMACS_INT; instead,
5775 report a string overflow if no precision given. When checking for
5776 precision exhaustion, use a check that cannot possibly have
5777 integer overflow. (Bug#8675)
5778 * character.h (lisp_string_width): Adjust to new signature.
5779
5780 * alloc.c (string_overflow): New function.
5781 (Fmake_string): Use it. This doesn't change behavior, but saves
5782 a few bytes and will simplify future changes.
5783 * character.c (string_escape_byte8): Likewise.
5784 * lisp.h (string_overflow): New decl.
5785
5786 Fixups, following up to the user-interface timestamp change.
5787 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
5788 for UI timestamps, instead of unsigned long.
5789 * msdos.c (mouse_get_pos): Likewise.
5790 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
5791 * w32gui.h (Time): Define by including "systime.h" rather than by
5792 declaring it ourselves. (Bug#8664)
5793
5794 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
5795 * image.c (clear_image_cache): Likewise.
5796
5797 * term.c (term_mouse_position): Don't assume time_t wraparound.
5798
5799 Be more systematic about user-interface timestamps.
5800 Before, the code sometimes used 'Time', sometimes 'unsigned long',
5801 and sometimes 'EMACS_UINT', to represent these timestamps.
5802 This change causes it to use 'Time' uniformly, as that's what X uses.
5803 This makes the code easier to follow, and makes it easier to catch
5804 integer overflow bugs such as Bug#8664.
5805 * frame.c (Fmouse_position, Fmouse_pixel_position):
5806 Use Time, not unsigned long, for user-interface timestamps.
5807 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
5808 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
5809 * keyboard.h (last_event_timestamp): Likewise.
5810 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
5811 * menu.h (xmenu_show): Likewise.
5812 * term.c (term_mouse_position): Likewise.
5813 * termhooks.h (struct input_event.timestamp): Likewise.
5814 (struct terminal.mouse_position_hook): Likewise.
5815 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
5816 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
5817 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
5818 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
5819 what it was before.
5820 * menu.h, termhooks.h: Include "systime.h", for Time.
5821
5822 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
5823 Don't assume that the difference between two unsigned long values
5824 can fit into an integer. At this point, we know button_down_time
5825 <= event->timestamp, so the difference must be nonnegative, so
5826 there's no need to cast the result if double-click-time is
5827 nonnegative, as it should be; check that it's nonnegative, just in
5828 case. This bug is triggered when events are more than 2**31 ms
5829 apart (about 25 days). (Bug#8664)
5830
5831 * xselect.c (last_event_timestamp): Remove duplicate decl.
5832 (x_own_selection): Remove needless cast to unsigned long.
5833
5834 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
5835 that always fit in int. Use a sentinel instead of a counter, to
5836 avoid a temp and to allay GCC's concerns about possible int overflow.
5837 * frame.h (struct frame): Use int for menu_bar_items_used
5838 instead of EMACS_INT, since it always fits in int.
5839
5840 * menu.c (grow_menu_items): Check for int overflow.
5841
5842 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
5843
5844 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
5845 Before, the code was not consistent. These values cannot exceed
5846 2**31 - 1 so there's no need to make them unsigned.
5847 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
5848 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
5849 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
5850 as modifiers.
5851 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
5852
5853 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
5854 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
5855 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
5856 presumably because the widths might not match.
5857
5858 * window.c (size_window): Avoid needless test at loop start.
5859
5860 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
5861
5862 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
5863
5864 2011-05-12 Drew Adams <drew.adams@oracle.com>
5865
5866 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
5867
5868 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5869
5870 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
5871 `width' to `bar_area_x' and `bar_area_width', respectively.
5872 (x_scroll_run): Take account of fringe background extension.
5873
5874 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
5875 Rename local vars `left' and `width' to `bar_area_x' and
5876 `bar_area_width', respectively.
5877 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
5878 background extension.
5879
5880 2011-05-10 Jim Meyering <meyering@redhat.com>
5881
5882 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
5883
5884 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
5885
5886 * image.c (Finit_image_library): Return t for built-in image types,
5887 like pbm and xbm. (Bug#8640)
5888
5889 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
5890
5891 * w32menu.c (set_frame_menubar): Fix submenu allocation.
5892
5893 2011-05-07 Eli Zaretskii <eliz@gnu.org>
5894
5895 * w32console.c (Fset_screen_color): Doc fix.
5896 (Fget_screen_color): New function.
5897 (syms_of_ntterm): Defsubr it.
5898
5899 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
5900 unlink the temporary file if Fcall_process didn't create it in the
5901 first place.
5902 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
5903 child process will be redirected to a file specified with `:file'.
5904 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
5905 cue to call_process_cleanup not to close that handle.
5906
5907 2011-05-07 Ben Key <bkey76@gmail.com>
5908
5909 * makefile.w32-in: The bootstrap-temacs rule now makes use of
5910 one of two shell specific rules, either bootstrap-temacs-CMD or
5911 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
5912 to the previous implementation of the bootstrap-temacs rule.
5913 The bootstrap-temacs-CMD rule is similar to the previous
5914 implementation of the bootstrap-temacs rule except that it
5915 makes use of the ESC_CFLAGS variable instead of the CFLAGS
5916 variable.
5917
5918 These changes, along with some changes to nt/configure.bat,
5919 nt/gmake.defs, and nt/nmake.defs, are required to extend my
5920 earlier fix to add support for --cflags and --ldflags options
5921 that include quotes so that it works whether make uses cmd or
5922 sh as the shell.
5923
5924 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
5925
5926 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
5927 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
5928 is a constant.
5929 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
5930 a string. Handle both cases.
5931 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
5932 (Fdbus_register_method): Use Qinvalid_function.
5933
5934 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
5935
5936 * makefile.w32-in: Update dependencies.
5937 (LISP_H): Add inttypes.h and stdin.h.
5938 (PROCESS_H): Add unistd.h.
5939
5940 2011-05-06 Eli Zaretskii <eliz@gnu.org>
5941
5942 * lread.c: Include limits.h (fixes the MS-Windows build broken by
5943 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
5944
5945 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
5946
5947 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
5948
5949 * term.c (vfatal): Remove stray call to va_end.
5950 It's not needed and the C Standard doesn't allow it here anyway.
5951
5952 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
5953 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
5954
5955 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
5956 bytes.
5957
5958 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
5959
5960 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
5961
5962 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
5963
5964 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
5965
5966 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
5967
5968 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
5969 * charset.c (Fdefine_charset_internal): Don't initialize
5970 charset.code_space[15]. The value was garbage, on hosts with
5971 32-bit int (Bug#8600).
5972
5973 * lread.c (read_integer): Be more consistent with string-to-number.
5974 Use string_to_number to do the actual conversion; this avoids
5975 rounding errors and fixes some other screwups. Without this fix,
5976 for example, #x1fffffffffffffff was misread as -2305843009213693952.
5977 (digit_to_number): Move earlier, for benefit of read_integer.
5978 Return -1 if the digit is out of range for the base, -2 if it is
5979 not a digit in any supported base. (Bug#8602)
5980
5981 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
5982
5983 * dispnew.c (scrolling_window): Return 1 if we scrolled,
5984 to match comment at start of function. This also removes a
5985 GCC warning about overflow in a 32+64-bit port.
5986
5987 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
5988
5989 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
5990 Reported by Stefan Monnier in
5991 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
5992 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
5993 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
5994
5995 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
5996 (EMACS_UINTPTR): Likewise, with uintptr_t.
5997
5998 * lisp.h: Prefer 64-bit EMACS_INT if available.
5999 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
6000 on 32-bit hosts that have 64-bit int, so that they can access
6001 large files.
6002 However, temporarily disable this change unless the temporary
6003 symbol WIDE_EMACS_INT is defined.
6004
6005 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
6006
6007 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
6008 This removes an assumption that EMACS_INT and long are the same
6009 width as pointers. The assumption is true for Emacs porting targets
6010 now, but we want to make other targets possible.
6011 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
6012 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
6013 In the rest of the code, change types of integers that hold casted
6014 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
6015 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
6016 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
6017 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
6018 No need to cast type when ORing.
6019 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
6020 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
6021 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
6022 assume EMACS_INT is the same width as char *.
6023 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
6024 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
6025 Remove no-longer-needed casts.
6026 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
6027 (xg_tool_bar_help_callback, xg_make_tool_item):
6028 Use EMACS_INTPTR to hold an integer
6029 that will be cast to void *; this can avoid a GCC warning
6030 if EMACS_INT is not the same width as void *.
6031 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
6032 * xdisp.c (display_echo_area_1, resize_mini_window_1):
6033 (current_message_1, set_message_1):
6034 Use a local to convert to proper width without a cast.
6035 * xmenu.c (dialog_selection_callback): Likewise.
6036
6037 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
6038 Also, don't assume VALBITS / RAND_BITS is less than 5,
6039 and don't rely on undefined behavior when shifting a 1 left into
6040 the sign bit.
6041 * lisp.h (get_random): Change signature to match.
6042
6043 * lread.c (hash_string): Use size_t, not int, for hash computation.
6044 Normally we prefer signed values; but hashing is special, because
6045 it's better to use unsigned division on hash table sizes so that
6046 the remainder is nonnegative. Also, size_t is the natural width
6047 for hashing into memory. The previous code used 'int', which doesn't
6048 retain enough info to hash well into very large tables.
6049 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
6050
6051 * dbusbind.c: Don't possibly lose pointer info when converting.
6052 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
6053 Use XPNTR rather than XHASH, so that the high-order bits of
6054 the pointer aren't lost when converting through void *.
6055
6056 * eval.c (Fautoload): Don't double-shift a pointer.
6057
6058 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
6059
6060 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
6061
6062 * gnutls.c (DEF_GNUTLS_FN):
6063 * image.c (DEF_IMGLIB_FN): Make function pointers static.
6064
6065 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
6066
6067 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
6068 marker. (Bug#8610)
6069
6070 2011-05-05 Eli Zaretskii <eliz@gnu.org>

6092 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
6093 Remove unused parameter `fildes'.
6094 * process.c (read_process_output, send_process): Don't pass it.
6095

6099 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
6100 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
6101
6102 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
6103
6104 Implement dynamic loading of GnuTLS on Windows.

6112 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
6113 (gnutls_*): Declare function pointers.
6114 (init_gnutls_functions): New function to initialize function pointers.
6115 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
6116 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
6117 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
6118 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
6119 (emacs_gnutls_write, emacs_gnutls_read)
6120 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
6121 (Fgnutls_available_p): New function.

6135 (w32_delayed_load): Move from image.c. When loading a library, record
6136 its filename in the :loaded-from property of the library id.
6137 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
6138 Initialize and staticpro them.
6139 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
6140
6141 * process.c: Include lisp.h before w32.h, not after.
6142 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
6143 instead of gnutls_record_check_pending.

6171 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
6172 (Qgnutls_bootprop_callbacks_verify): Make static.
6173
6174 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
6175

6177
6178 * sysdep.c (wait_for_termination_1): Make static.
6179 (wait_for_termination, interruptible_wait_for_termination):
6180 Move after wait_for_termination_1.
6181
6182 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
6183
6184 * sysdep.c (interruptible_wait_for_termination): New function
6185 which is like wait_for_termination, but allows keyboard
6186 interruptions.
6187
6188 * callproc.c (Fcall_process): Add (:file "file") as an option for
6189 the STDOUT buffer.
6190 (Fcall_process_region): Ditto.

6208 will grow beyond MOST_POSITIVE_FIXNUM.
6209 (decode_coding_emacs_mule): Abort if there isn't enough place in
6210 charbuf for the composition carryover bytes. Reserve an extra
6211 space for up to 2 characters produced in a loop.
6212 (decode_coding_iso_2022): Abort if there isn't enough place in
6213 charbuf for the composition carryover bytes.
6214
6215 2011-04-21 Eli Zaretskii <eliz@gnu.org>
6216
6217 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
6218 aborting when %lld or %lll format is passed.

6251
6252 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
6253 (Fx_window_property): #if-0 the whole functions, not just the bodies.
6254
6255 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
6256
6257 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
6258
6259 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
6260
6261 * makefile.w32-in: Update dependencies.
6262
6263 2011-04-27 Eli Zaretskii <eliz@gnu.org>
6264
6265 Improve `doprnt' and its usage. (Bug#8545)
6266 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
6267 `format_end'. Remove support for %l as a conversion specifier.
6268 Don't use xrealloc. Improve diagnostics when the %l size modifier
6269 is used. Update the commentary.
6270
6271 * eval.c (verror): Simplify calculation of size_t.
6272
6273 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
6274 messages.
6275
6276 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
6277
6278 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
6279 change.
6280
6281 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
6282
6283 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
6284 This makes this file independent of the recent pseudovector change.
6285
6286 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
6287
6288 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
6289
6290 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
6291 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
6292 Remove unused local.
6293 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
6294
6295 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
6296 GCC 4.6.0 optimizes based on type-based alias analysis.
6297 For example, if b is of type struct buffer * and v of type struct
6298 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
6299 != &v->size, and therefore "v->size = 1; b->size = 2; return
6300 v->size;" must therefore return 1. This assumption is incorrect
6301 for Emacs, since it type-puns struct Lisp_Vector * with many other
6302 types. To fix this problem, this patch adds a new type struct
6303 vectorlike_header that documents the constraints on layout of vectors
6304 and pseudovectors, and helps optimizing compilers not get fooled
6305 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
6306 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
6307 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
6308 the size member.
6309 (XSETPVECTYPE): Rewrite in terms of new macro.
6310 (XSETPVECTYPESIZE): New macro, specifying both type and size.
6311 This is a bit clearer, and further avoids the possibility of
6312 undesirable aliasing.
6313 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
6314 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
6315 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
6316 since Lisp_Subr is a special case (no "next" field).
6317 (ASIZE): Now uses header.size rather than size.
6318 All previous uses of XVECTOR (foo)->size replaced to use this macro,
6319 to avoid the hassle of writing XVECTOR (foo)->header.size.
6320 (struct vectorlike_header): New type.
6321 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
6322 object, to help avoid aliasing.
6323 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
6324 (SUBRP): Likewise, since Lisp_Subr is a special case.
6325 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
6326 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
6327 (struct Lisp_Hash_Table): Combine first two members into a single
6328 struct vectorlike_header member. All uses of "size" and "next" members
6329 changed to be "header.size" and "header.next".
6330 * buffer.h (struct buffer): Likewise.
6331 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
6332 * frame.h (struct frame): Likewise.
6333 * process.h (struct Lisp_Process): Likewise.
6334 * termhooks.h (struct terminal): Likewise.
6335 * window.c (struct save_window_data, struct saved_window): Likewise.
6336 * window.h (struct window): Likewise.
6337 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
6338 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
6339 * buffer.c (init_buffer_once): Likewise.
6340 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
6341 special case.
6342 * process.c (Fformat_network_address): Use local var for size,
6343 for brevity.
6344
6345 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
6346
6347 Make the Lisp reader and string-to-float more consistent (Bug#8525)
6348 * data.c (atof): Remove decl; no longer used or needed.
6349 (digit_to_number): Move to lread.c.
6350 (Fstring_to_number): Use new string_to_number function, to be
6351 consistent with how the Lisp reader treats infinities and NaNs.
6352 Do not assume that floating-point numbers represent EMACS_INT
6353 without losing information; this is not true on most 64-bit hosts.
6354 Avoid double-rounding errors, by insisting on integers when
6355 parsing non-base-10 numbers, as the documentation specifies.
6356 * lisp.h (string_to_number): New decl, replacing ...
6357 (isfloat_string): Remove.
6358 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
6359 (read1): Do not accept +. and -. as integers; this
6360 appears to have been a coding error. Similarly, do not accept
6361 strings like +-1e0 as floating point numbers. Do not report
6362 overflow for integer overflows unless the base is not 10 which
6363 means we have no simple and reliable way to continue.
6364 Break out the floating-point parsing into a new
6365 function string_to_number, so that Fstring_to_number parses
6366 floating point numbers consistently with the Lisp reader.
6367 (digit_to_number): Move here from data.c. Make it static inline.
6368 (E_CHAR, EXP_INT): Remove, replacing with ...
6369 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
6370 (string_to_number): New function, replacing isfloat_string.
6371 This function checks for valid syntax and produces the resulting
6372 Lisp float number too. Rework it so that string-to-number
6373 no longer mishandles examples like "1.0e+". Use strtoumax,
6374 so that overflow for non-base-10 numbers is reported only when
6375 there's no portable and simple way to convert to floating point.
6376
6377 * textprop.c (set_text_properties_1): Rewrite for clarity,
6378 and to avoid GCC warning about integer overflow.
6379
6380 * intervals.h (struct interval): Use EMACS_INT for members
6381 where EMACS_UINT might cause problems. See
6382 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
6383 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
6384 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
6385 All uses changed.
6386 (offset_intervals): Tell GCC not to worry about length overflow
6387 when negating a negative length.
6388
6389 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
6390 (overrun_check_free): Likewise.
6391
6392 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
6393 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
6394 word size.
6395
6396 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
6397 (gnutls_make_error): Rename local to avoid shadowing.
6398 (gnutls_emacs_global_deinit): ifdef out; not used.
6399 (Fgnutls_boot): Use const for pointer to readonly storage.
6400 Comment out unused local. Fix pointer signedness problems.
6401
6402 * lread.c (openp): Don't stuff size_t into an 'int'.
6403 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
6404 about possible signed overflow.
6405
6406 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
6407 (GDK_KEY_g): Don't define if already defined.
6408 (xg_prepare_tooltip): Avoid pointer signedness problem.
6409 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
6410
6411 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
6412 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
6413
6414 * xfns.c (Fx_window_property): Simplify a bit,
6415 to make a bit faster and to avoid GCC 4.6.0 warning.
6416 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
6417
6418 * fns.c (internal_equal): Don't assume size_t fits in int.
6419
6420 * alloc.c (compact_small_strings): Tighten assertion a little.
6421
6422 Replace pEd with more-general pI, and fix some printf arg casts.
6423 * lisp.h (pI): New macro, generalizing old pEd macro to other
6424 conversion specifiers. For example, use "...%"pI"d..." rather
6425 than "...%"pEd"...".
6426 (pEd): Remove. All uses replaced with similar uses of pI.
6427 * src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h: Likewise.
6428 * alloc.c (check_pure_size): Don't overflow by converting size to int.
6429 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
6430 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
6431 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
6432 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
6433 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
6434 64-bit hosts.
6435 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
6436 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
6437 * print.c (safe_debug_print, print_object): Likewise.
6438 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
6439 to int.
6440 Use pI instead of if-then-else-abort. Use %p to avoid casts,
6441 avoiding the 0 flag, which is not portable.
6442 * process.c (Fmake_network_process): Use pI to avoid cast.
6443 * region-cache.c (pp_cache): Likewise.
6444 * xdisp.c (decode_mode_spec): Likewise.
6445 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
6446 behavior on 64-bit hosts with printf arg.
6447 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
6448 (x_stop_queuing_selection_requests): Likewise.
6449 (x_get_window_property): Don't truncate byte count to an 'int'
6450 when tracing.
6451
6452 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
6453 here, since it parses constructs like leading '-' and spaces,
6454 which are not wanted; and it overflows with large numbers.
6455 Instead, simply match F[0-9]+, which is what is wanted anyway.
6456
6457 * alloc.c: Remove unportable assumptions about struct layout.
6458 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
6459 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
6460 (allocate_vectorlike, make_pure_vector): Use the new macros,
6461 plus offsetof, to remove unportable assumptions about struct layout.
6462 These assumptions hold on all porting targets that I know of, but
6463 they are not guaranteed, they're easy to remove, and removing them
6464 makes further changes easier.
6465
6466 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
6467 This doesn't fix a bug but makes the code clearer.
6468 (string_overrun_cookie): Now const. Use initializers that
6469 don't formally overflow signed char, to avoid warnings.
6470 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
6471 can cause Emacs to crash when string overrun checking is enabled.
6472 (allocate_buffer): Don't assume sizeof (struct buffer) is a
6473 multiple of sizeof (EMACS_INT); it need not be, if
6474 alignof(EMACS_INT) < sizeof (EMACS_INT).
6475 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
6476
6477 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
6478
6479 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
6480

6482
6483 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
6484 supposed to be handshaking. (Bug#8556)
6485 Reported by Paul Eggert <eggert@cs.ucla.edu>.
6486
6487 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
6488
6489 * lisp.h (Qdebug): List symbol.
6490 * eval.c (Qdebug): Restore global linkage.
6491 * keyboard.c (debug-on-event): New variable.
6492 (handle_user_signal): Break into debugger when debug-on-event
6493 matches the current signal symbol.
6494
6495 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
6496
6497 * alloc.c (check_sblock, check_string_bytes)
6498 (check_string_free_list): Convert to standard C.
6499
6500 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
6501
6502 * w32.c (emacs_gnutls_push): Fix typo.
6503
6504 2011-04-25 Eli Zaretskii <eliz@gnu.org>
6505
6506 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
6507 "cast to pointer from integer of different size".
6508
6509 Improve doprnt and its use in verror. (Bug#8545)
6510 * doprnt.c (doprnt): Document the set of format control sequences
6511 supported by the function. Use SAFE_ALLOCA instead of always
6512 using `alloca'.
6513
6514 * eval.c (verror): Don't limit the buffer size at size_max-1, that
6515 is one byte too soon. Don't use xrealloc; instead xfree and
6516 xmalloc anew.
6517
6518 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
6519
6520 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
6521 callbacks stage.
6522
6523 * gnutls.c: Renamed global_initialized to
6524 gnutls_global_initialized. Added internals for the
6525 :verify-hostname-error, :verify-error, and :verify-flags
6526 parameters of `gnutls-boot' and documented those parameters in the
6527 docstring. Start callback support.
6528 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
6529 unless a fatal error occurred. Call gnutls_alert_send_appropriate
6530 on error. Return error code.
6531 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
6532 (emacs_gnutls_read): Likewise.
6533 (Fgnutls_boot): Return handshake error code.
6534 (emacs_gnutls_handle_error): New function.

6544
6545 * process.c (wait_reading_process_output): Check if GnuTLS
6546 buffered some data internally if no FDs are set for TLS
6547 connections.
6548

6554
6555 * xdisp.c (handle_single_display_spec): Rename the
6556 display_replaced_before_p argument into display_replaced_p, to
6557 make it consistent with the commentary. Fix typos in the
6558 commentary.
6559
6560 * textprop.c (syms_of_textprop): Remove dead code.
6561 (copy_text_properties): Delete obsolete commentary about an
6562 interface that was deleted long ago. Fix typos in the description
6563 of arguments.

6566 to changes in oldXMenu/XMenu.h from 2011-04-16.
6567 <menu_help_message, prev_menu_help_message>: Constify.
6568 (IT_menu_make_room): menu->help_text is now `const char **';
6569 adjust.
6570
6571 * msdos.h (XMenuActivate, XMenuAddSelection): Adjust prototypes
6572 to changes in oldXMenu/XMenu.h from 2011-04-16.

6575 * xfaces.c <Qunspecified>: Make extern again.
6576
6577 * syntax.c: Include sys/types.h before including regex.h, as
6578 required by Posix.

6581
6582 * doprnt.c (doprnt): Improve commentary.
6583
6584 * term.c (init_tty) [MSDOS]: Fix 1st argument to maybe_fatal.
6585
6586 * Makefile.in (TAGS): Depend on $(M_FILE) and $(S_FILE), and scan
6587 them with etags.
6588
6589 * makefile.w32-in (globals.h): Add a dummy recipe, to make any
6590 changes in globals.h immediately force recompilation.
6591 (TAGS): Depend on $(CURDIR)/m/intel386.h and
6592 $(CURDIR)/s/ms-w32.h.
6593 (TAGS-gmake): Scan $(CURDIR)/m/intel386.h and $(CURDIR)/s/ms-w32.h.
6594
6595 * character.c (Fchar_direction): Function deleted.
6596 (syms_of_character): Don't defsubr it.
6597 <char-direction-table>: Deleted.
6598
6599 2011-04-23 Eli Zaretskii <eliz@gnu.org>
6600
6601 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
6602 * doprnt.c: Include limits.h.
6603 (SIZE_MAX): New macro.
6604 (doprnt): Return a size_t value. 2nd arg is now size_t.
6605 Many local variables are now size_t instead of int or unsigned.
6606 Improve overflow protection. Support `l' modifier for integer
6607 conversions. Support %l conversion. Don't assume an EMACS_INT
6608 argument for integer conversions and for %c.
6609
6610 * lisp.h (doprnt): Restore prototype.
6611
6612 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
6613 $(SRC)/character.h.
6614
6615 * Makefile.in (base_obj): Add back doprnt.o.
6616
6617 * deps.mk (doprnt.o): Add back prerequisites.
6618 (callint.o): Depend on character.h.
6619
6620 * eval.c (internal_lisp_condition_case): Include the handler
6621 representation in the error message.
6622 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
6623 when breaking from the loop.
6624
6625 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
6626
6627 * callint.c (Fcall_interactively): When displaying error message
6628 about invalid control letter, pass the character's codepoint, not
6629 a pointer to its multibyte form. Improve display of the character
6630 in octal and display also its hex code.
6631
6632 * character.c (char_string): Use %x to display the (unsigned)
6633 codepoint of an invalid character, to avoid displaying a bogus
6634 negative value.
6635
6636 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
6637 `error', not SYMBOL_NAME itself.
6638
6639 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
6640 character arguments to `error'.
6641
6642 * charset.c (check_iso_charset_parameter): Fix incorrect argument
6643 to `error' in error message about FINAL_CHAR argument. Make sure
6644 FINAL_CHAR is a character, and use %c when it is passed as
6645 argument to `error'.
6646

6664
6665 2011-04-19 Eli Zaretskii <eliz@gnu.org>
6666
6667 * syntax.h (SETUP_SYNTAX_TABLE_FOR_OBJECT): Fix setting of

6833
6834 * nsfont.m: Fixed bugs in ns_get_family and
6835 ns_descriptor_to_entity that were caused by using free to

6838 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
6839 --enable-checking=xmallocoverrun). xfree is now used to
6840 deallocate these memory blocks.

7194 so that it's not optimized away.
7195 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
7196 * dispextern.h (bidi_dump_cached_states): Remove, since it's
7197 exported only to the debugger.
7198
7199 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
7200 * atimer.h (run_all_atimers): Remove; not exported.
7201
7202 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
7203 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
7204 was inaccessible from Lisp.

7207
7208 alloc.c: Import and export fewer symbols, and remove unused items.
7209 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
7210 is defined.
7211 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
7212 it's not optimized away by whole-program optimization.

7228 Declare Lisp_Object Q* variables to be 'static' if not exported.
7229 This makes it easier for human readers (and static analyzers)
7230 to see whether these variables are used from other modules.
7231 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:

7242 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
7243
7244 * lisp.h (DEFINE_FUNC): Make sname 'static'.
7245
7246 Make Emacs functions such as Fatom 'static' by default.
7247 This makes it easier for human readers (and static analyzers)
7248 to see whether these functions can be called from other modules.
7249 DEFUN now defines a static function. To make the function external
7250 so that it can be used in other C modules, use the new macro DEFUE.
7251 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
7252 (Finit_image_library):
7253 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
7254 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
7255 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
7256 Remove decls, since these functions are now static.
7257 (Funintern, Fget_internal_run_time): New decls, since these functions
7258 were already external.
7259
7260 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:

7268 Mark functions with DEFUE instead of DEFUN,
7269 if they are used in other modules.
7270 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
7271 decls for now-static functions.
7272 * buffer.h (Fdelete_overlay): Remove decl.
7273 * callproc.c (Fgetenv_internal): Mark as internal.
7274 * composite.c (Fremove_list_of_text_properties): Remove decl.

7300

7303 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
7304
7305 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
7306 change. (Bug#8496)
7307
7308 2011-04-13 Eli Zaretskii <eliz@gnu.org>
7309
7310 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
7311 when at ZV. (Bug#8487)
7312
7313 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
7314
7315 * charset.c (Fclear_charset_maps): Use xfree instead of free.
7316 (Bug#8437)
7317 * keyboard.c (parse_tool_bar_item): Likewise.
7318 * sound.c (sound_cleanup, alsa_close): Likewise.

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

7509
7510 * process.c (Fformat_network_address): Doc fix.
7511
7512 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
7513

7515
7516 2011-04-08 Chong Yidong <cyd@stupidchicken.com>

7562 This avoids several warnings with gcc -Wstrict-overflow.
7563 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
7564 directly, rather than having caller test rule sign. This avoids
7565 some unnecessary tests.
7566 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
7567 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
7568 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
7569
7570 * xfont.c (xfont_text_extents): Remove var that was set but not used.
7571 (xfont_open): Avoid unnecessary tests.
7572
7573 * composite.c (composition_gstring_put_cache): Use unsigned integer.

7579 breaking out part of COMPOSITION_DECODE_RULE.
7580 (COMPOSITION_DECODE_RULE): Use it.
7581 * composite.c (get_composition_id): Remove unused local vars,
7582 by using the new macro.
7583
7584 * textprop.c (set_text_properties_1): Change while to do-while,
7585 since the condition is always true at first.
7586
7587 * intervals.c (graft_intervals_into_buffer): Mark var as used.
7588 (interval_deletion_adjustment): Return unsigned value.
7589 All uses changed.
7590
7591 * process.c (list_processes_1, create_pty, read_process_output):
7592 (exec_sentinel): Remove vars that were set but not used.

7602
7603 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
7604 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
7605 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
7606
7607 * print.c (print_error_message): Avoid int overflow.
7608
7609 * font.c (font_list_entities): Redo for clarity,
7610 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
7611
7612 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
7613 (font_score): Avoid potential overflow in diff calculation.
7614
7615 * fns.c (substring_both): Remove var that is set but not used.
7616 (sxhash): Redo loop for clarity and to avoid wraparound warning.
7617
7618 * eval.c (funcall_lambda): Rename local to avoid shadowing.
7619
7620 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
7621 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
7622 can always succeed if overflow has undefined behavior.
7623
7624 * search.c (boyer_moore, wordify): Remove vars set but not used.
7625 (wordify): Omit three unnecessary tests.
7626
7627 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.

7643 but not used.
7644
7645 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):

7649
7650 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
7651
7652 * image.c (lookup_image): Remove var that is set but not used.
7653 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
7654
7655 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
7656 that are set but not used.
7657
7658 * xfns.c (make_invisible_cursor): Don't return garbage
7659 if XCreateBitmapFromData fails (Bug#8410).
7660
7661 * xselect.c (x_get_local_selection, x_handle_property_notify):
7662 Remove vars that are set but not used.
7663
7664 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
7665 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
7666
7667 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
7668 Remove var that is set but not used.
7669 (scroll_bar_windows_size): Now size_t, not int.
7670 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
7671 Check for overflow.
7672
7673 * xfaces.c (realize_named_face): Remove vars that are set but not used.
7674 (map_tty_color) [!defined MSDOS]: Likewise.
7675
7676 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
7677
7678 * coding.c: Remove vars that are set but not used.
7679 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
7680 All callers changed.
7681 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
7682 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
7683 (decode_coding_charset): Remove vars that are set but not used.
7684
7685 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
7686 that is set but not used.
7687
7688 * print.c (print_object): Remove var that is set but not used.
7689
7690 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
7691 The gnulib version avoids calling malloc in the usual case,
7692 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
7693 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
7694 * filelock.c (current_lock_owner): Likewise.
7695 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
7696 * sysdep.c: Include allocator.h, careadlinkat.h.
7697 (emacs_no_realloc_allocator): New static constant.
7698 (emacs_readlink): New function.
7699 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
7700 ../lib/careadlinkat.h.
7701
7702 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
7703
7704 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
7705 first non-nil return value).
7706
7707 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
7708
7709 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
7710 if not defined (Bug#8403).
7711
7712 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
7713
7714 * xdisp.c (display_count_lines): Remove parameter `start',
7715 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.

7729
7730 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
7731
7732 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
7733
7734 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
7735
7736 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
7737 later (Bug#8403).
7738
7739 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
7740
7741 Add lexical binding.
7742
7743 * window.c (Ftemp_output_buffer_show): New fun.
7744 (Fsave_window_excursion):
7745 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
7746
7747 * lread.c (lisp_file_lexically_bound_p): New function.
7748 (Fload): Bind Qlexical_binding.
7749 (readevalloop): Remove `evalfun' arg.
7750 Bind Qinternal_interpreter_environment.
7751 (Feval_buffer): Bind Qlexical_binding.
7752 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
7753 Mark as dynamic.
7754 (syms_of_lread): Declare `lexical-binding'.
7755
7756 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
7757
7758 * keyboard.c (eval_dyn): New fun.
7759 (menu_item_eval_property): Use it.
7760
7761 * image.c (parse_image_spec): Use Ffunctionp.
7762
7763 * fns.c (concat, mapcar1): Accept byte-code-functions.
7764
7765 * eval.c (Fsetq): Handle lexical vars.
7766 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
7767 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
7768 (FletX, Flet): Obey lexical binding.
7769 (Fcommandp): Handle closures.
7770 (Feval): New `lexical' arg.
7771 (eval_sub): New function extracted from Feval. Use it almost
7772 everywhere where Feval was used. Look up vars in lexical env.
7773 Handle closures.
7774 (Ffunctionp): Move from subr.el.
7775 (Ffuncall): Handle closures.
7776 (apply_lambda): Remove `eval_flags'.
7777 (funcall_lambda): Handle closures and new byte-code-functions.
7778 (Fspecial_variable_p): New function.
7779 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
7780 but without exporting it to Lisp.
7781
7782 * doc.c (Fdocumentation, store_function_docstring):
7783 * data.c (Finteractive_form): Handle closures.
7784
7785 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
7786 interactive spec.
7787
7788 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
7789 New byte-codes.
7790 (exec_byte_code): New function extracted from Fbyte_code to handle new
7791 calling convention for byte-code-functions. Add new byte-codes.
7792
7793 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
7794
7795 * alloc.c (Fmake_symbol): Init new `declared_special' field.
7796
7797 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
7798
7799 * xdisp.c (redisplay_internal): Fix prototype.
7800
7801 2011-03-31 Eli Zaretskii <eliz@gnu.org>
7802
7803 * xdisp.c (SCROLL_LIMIT): New macro.
7804 (try_scrolling): Use it when setting scroll_limit.
7805 Limit scrolling to 100 screen lines.
7806 (redisplay_window): Even when falling back on "recentering",
7807 position point in the window according to scroll-conservatively,
7808 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
7809
7810 (try_scrolling): When point is above the window, allow searching
7811 as far as scroll_max, or one screenful, to compute vertical
7812 distance from PT to the scroll margin position. This prevents
7813 try_scrolling from unnecessarily failing when
7814 scroll-conservatively is set to a value slightly larger than the
7815 window height. Clean up the case of PT below the margin at bottom
7816 of window: scroll_max can no longer be INT_MAX. When aggressive
7817 scrolling is in use, don't let point enter the opposite scroll
7818 margin as result of the scroll.
7819 (syms_of_xdisp) <scroll-conservatively>: Document the
7820 threshold of 100 lines for never-recentering scrolling.
7821
7822 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
7823
7824 * dispextern.h (move_it_by_lines):
7825 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
7826 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
7827 (message_log_check_duplicate): Remove parameters `prev_bol' and
7828 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
7829 (redisplay_internal): Remove parameter `preserve_echo_area',
7830 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
7831
7832 * indent.c (Fvertical_motion):
7833 * window.c (window_scroll_pixel_based, Frecenter):
7834 Don't pass `need_y_p' to `move_it_by_lines'.
7835
7836 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
7837
7838 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
7839 steal a few bits to be more compact.
7840 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
7841 Remove unneeded casts.
7842
7843 * bytecode.c (Fbyte_code): CAR and CDR can GC.
7844
7845 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
7846
7847 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
7848 binding" message (bug#7967).
7849
7850 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
7851
7852 Fix more problems found by GCC 4.6.0's static checks.
7853
7854 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
7855 Remove unused local var.
7856
7857 * editfns.c (Fmessage_box): Remove unused local var.
7858
7859 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
7860 (note_mode_line_or_margin_highlight, note_mouse_highlight):
7861 Omit unused local vars.
7862 * window.c (shrink_windows): Omit unused local var.
7863 * menu.c (digest_single_submenu): Omit unused local var.
7864 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
7865 Omit unused local var.
7866
7867 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
7868 Don't assume string length fits in int.
7869 (keyremap_step, read_key_sequence): Use size_t for sizes.
7870 (read_key_sequence): Don't check last_real_key_start redundantly.
7871
7872 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
7873 instead of alloca (Bug#8344).
7874
7875 * eval.c (Fbacktrace): Don't assume nargs fits in int.
7876 (Fbacktrace_frame): Don't assume nframes fits in int.
7877
7878 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
7879
7880 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
7881 concerns.
7882
7883 * term.c (produce_glyphless_glyph): Remove unnecessary test.
7884
7885 * cm.c (calccost): Turn while-do into do-while, for clarity.
7886
7887 * keyboard.c (syms_of_keyboard): Use the same style as later
7888 in this function when indexing through an array. This also
7889 works around GCC bug 48267.
7890
7891 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
7892
7893 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
7894
7895 * chartab.c (sub_char_table_ref_and_range): Redo for slight
7896 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
7897
7898 * keyboard.c, keyboard.h (num_input_events): Now size_t.
7899 This avoids undefined behavior on integer overflow, and is a bit
7900 more convenient anyway since it is compared to a size_t variable.
7901
7902 Variadic C functions now count arguments with size_t, not int.
7903 This avoids an unnecessary limitation on 64-bit machines, which
7904 caused (substring ...) to crash on large vectors (Bug#8344).

8132 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
8133
8134 Fix more problems found by GCC 4.5.2's static checks.
8135
8136 * coding.c (encode_coding_raw_text): Avoid unnecessary test
8137 the first time through the loop, since we know p0 < p1 then.
8138 This also avoids a gcc -Wstrict-overflow warning.
8139
8140 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
8141 leading to a memory leak, possible in functions like
8142 load_charset_map_from_file that can allocate an unbounded number
8143 of objects (Bug#8318).
8144
8145 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
8146 that could (at least in theory) be that large.
8147
8148 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
8149 This is less likely to overflow, and avoids undefined behavior if
8150 overflow does occur. All callers changed. Use strtoul to scan
8151 for the unsigned long integer.
8152 (pint2hrstr): Simplify and tune code slightly.
8153 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

8162
8163 * fileio.c (Fcopy_file): Report error if fchown or fchmod

8167
8168 * process.c (Fmake_network_process): Use socklen_t, not int,
8169 where POSIX says socklen_t is required in portable programs.
8170 This fixes a porting bug on hosts like 64-bit HP-UX, where
8171 socklen_t is wider than int (Bug#8277).
8172 (Fmake_network_process, server_accept_connection):
8173 (wait_reading_process_output, read_process_output):
8174 Likewise.
8175
8176 * process.c: Rename or move locals to avoid shadowing.

8183 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
8184 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
8185
8186 Make tparam.h and terminfo.c consistent.
8187 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
8188 Include tparam.h instead, since it declares them.
8189 * cm.h (PC): Remove extern decl; tparam.h now does this.
8190 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
8191 * terminfo.c: Include tparam.h, to check interfaces.
8192 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
8193 (tparam): Adjust signature to match interface in tparam.h;
8194 this removes some undefined behavior. Check that outstring and len
8195 are zero, which they always are with Emacs.
8196 * tparam.h (PC, BC, UP): New extern decls.
8197
8198 * xftfont.c (xftfont_shape): Now static, and defined only if needed.

8212
8213 * composite.c (composition_compute_stop_pos): Rename local to
8214 avoid shadowing.
8215 (composition_reseat_it): Remove unused locals.
8216 (find_automatic_composition, composition_adjust_point): Likewise.
8217 (composition_update_it): Mark var as initialized.
8218 (find_automatic_composition): Mark vars as initialized,
8219 with a FIXME (Bug#8290).
8220
8221 character.h: Rename locals to avoid shadowing.
8222 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
8223 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
8224 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
8225 (BUF_DEC_POS): Be more systematic about renaming local temporaries
8226 to avoid shadowing.
8227
8228 * textprop.c (property_change_between_p): Remove; unused.
8229
8230 * intervals.c (interval_start_pos): Now static.

8235 Rename locals to avoid shadowing.
8236
8237 * sound.c (wav_play, au_play, Fplay_sound_internal):
8238 Fix pointer signedness.
8239 (alsa_choose_format): Remove unused local var.
8240 (wav_play): Initialize a variable to 0, to prevent undefined
8241 behavior (Bug#8278).
8242
8243 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
8244
8245 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
8246
8247 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
8248 clobbering (Bug#8298).
8249 * sysdep.c (sys_subshell): Likewise.
8250 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
8251
8252 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
8253 This should get cleaned up, so that child_setup has the
8254 same signature on all platforms.
8255
8256 * callproc.c (call_process_cleanup): Now static.
8257 (relocate_fd): Rename locals to avoid shadowing.
8258
8259 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
8260
8261 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
8262 not to be necessary, and produces flickering.
8263
8264 2011-03-20 Glenn Morris <rgm@gnu.org>
8265
8266 * config.in: Remove file.
8267

8298 (sigchld_handler): Now static.
8299
8300 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
8301 That way, the code declares only the vars that it needs.

8303 * s/cygwin.h (PTY_ITERATION): Likewise.
8304 * s/darwin.h (PTY_ITERATION): Likewise.

8306
8307 * s/irix6-5.h (PTY_OPEN): Declare stb, to loosen coupling.
8308 * process.c (allocate_pty): Don't declare stb unless it's needed.

8383 Move decls here, to check interfaces.
8384 * process.c (get_operating_system_release): Move decl to lisp.h.
8385 * xrdb.c (get_system_name): Likewise.
8386 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
8387 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
8388 some of which prompt warnings from gcc -Wbad-function-cast.
8389 (Fformat_time_string, Fencode_time, Finsert_char):
8390 (Ftranslate_region_internal, Fformat):

8398 ENABLE_CHECKING is not defined.
8399

8417 (GC_STRING_CHARS): Remove; not used.
8418 (Fmemory_limit): Cast sbrk's returned value to char *.
8419
8420 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this

8422
8423 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
8424
8425 Use functions, not macros, for up- and down-casing (Bug#8254).
8426 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
8427 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
8428 to use the following functions instead of these macros.
8429 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
8430 EMACS_INT, since callers assume the returned value fits in int.
8431 (upcase1): Likewise, for UPCASE_TABLE.
8432 (uppercasep, lowercasep, upcase): New static inline functions.
8433 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

8439 (regex_compile, re_search_2, re_match_2_internal):
8440 Remove unused local vars.

8442 which gcc can warn about.
8443 (regex_compile, re_match_2_internal): Mark locals as initialized.
8444 (RETALLOC_IF): Define only if needed.
8445 (WORDCHAR_P): Likewise. This one is never needed, but is used
8446 only in a comment talking about a compiler bug, so put inside
8447 the #if 0 of that comment.
8448 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
8449 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
8450 Remove; unused.

8461
8462 * character.h (INC_POS, DEC_POS): Rename locals to avoid shadowing.
8463
8464 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
8465 All uses changed.
8466 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
8467 Rename locals to avoid shadowing.
8468 (Fvertical_motion): Mark locals as initialized.
8469
8470 * casefiddle.c (casify_object, casify_region): Now static.

8474
8475 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
8476 New macros, so that the caller can use some names other than
8477 gcpro1, gcpro2, etc.
8478 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
8479 of the new macros.
8480 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
8481 argument, for consistency with GCPRO2_VAR, etc: it is now the
8482 prefix of the variable, not the variable itself. All uses
8483 changed.
8484 * dired.c (directory_files_internal, file_name_completion):
8485 Rename locals to avoid shadowing.
8486
8487 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
8488 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
8489 dired.c's scmp function, had undefined behavior.
8490 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
8491 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
8492 * buffer.h: ... to here, because these macros use current_buffer,
8493 and the new implementation with inline functions needs to have
8494 current_buffer in scope now, rather than later when the macros
8495 are used.
8496 (downcase, upcase1): New static inline functions.
8497 (DOWNCASE, UPCASE1): Reimplement using these functions.
8498 This avoids undefined behavior in expressions like
8499 DOWNCASE (x) == DOWNCASE (y), which previously suffered
8500 from race conditions in accessing the global variables
8501 case_temp1 and case_temp2.
8502 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
8503 * lisp.h (case_temp1, case_temp2): Remove their decls.
8504 * character.h (ASCII_CHAR_P): Move from here ...
8505 * lisp.h: ... to here, so that the inline functions mentioned
8506 above can use them.
8507
8508 * dired.c (directory_files_internal_unwind): Now static.
8509
8510 * fileio.c (file_name_as_directory, directory_file_name):
8511 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
8512 Now static.
8513 (file_name_as_directory): Use const pointers when appropriate.
8514 (Fexpand_file_name): Likewise. In particular, newdir might
8515 point at constant storage, so make it a const pointer.
8516 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
8517 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
8518 signedness issues.
8519 (Fset_file_times, Finsert_file_contents, auto_save_error):
8520 Rename locals to avoid shadowing.
8521
8522 * minibuf.c (choose_minibuf_frame_1): Now static.
8523 (Ftry_completion, Fall_completions): Rename or remove locals
8524 to avoid shadowing.
8525
8526 * marker.c (bytepos_to_charpos): Remove; unused.
8527
8528 * lisp.h (verify_bytepos, count_markers): New decls,
8529 so that gcc does not warn that these functions aren't declared.
8530
8531 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
8532 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
8533 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
8534 (copy_text): Remove unused local var.
8535
8536 * filelock.c (within_one_second): Now static.
8537 (lock_file_1): Rename local to avoid shadowing.
8538
8539 * buffer.c (fix_overlays_before): Mark locals as initialized.
8540 (fix_start_end_in_overlays): Likewise. This function should be
8541 simplified by using pointers-to-pointers, but that's a different
8542 matter.
8543 (switch_to_buffer_1): Now static.
8544 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
8545 (report_overlay_modification): Rename locals to avoid shadowing.
8546
8547 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
8548 Fix pointer signedness issue.
8549 (sys_subshell): Mark local as volatile if checking for lint,
8550 to suppress a gcc -Wclobbered warning that does not seem to be right.
8551 (MAXPATHLEN): Define only if needed.
8552
8553 * process.c (serial_open, serial_configure): Move decls from here ...
8554 * systty.h: ... to here, so that they can be checked.
8555
8556 * fns.c (get_random, seed_random): Move extern decls from here ...
8557 * lisp.h: ... to here, so that they can be checked.
8558
8559 * sysdep.c (reset_io): Now static.
8560 (wait_for_termination_signal): Remove; unused.
8561
8562 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
8563 (copy_keymap_item, append_key, push_text_char_description):
8564 Now static.
8565 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
8566 (DENSE_TABLE_SIZE): Remove; unused.
8567 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
8568 (describe_map_tree):
8569 Rename locals to avoid shadowing.
8570
8571 * keyboard.c: Declare functions static if they are not used elsewhere.
8572 (echo_char, echo_dash, cmd_error, top_level_2):
8573 (poll_for_input, handle_async_input): Now static.
8574 (read_char, kbd_buffer_get_event, make_lispy_position):
8575 (make_lispy_event, make_lispy_movement, apply_modifiers):
8576 (decode_keyboard_code, tty_read_avail_input, menu_bar_items):

8585
8586 * lisp.h (force_auto_save_soon): New decl.
8587
8588 * emacs.c (init_cmdargs): Rename local to avoid shadowing.
8589 (DEFINE_DUMMY_FUNCTION): New macro.
8590 (__do_global_ctors, __do_global_ctors_aux, __do_global_dtors, __main):
8591 Use it.
8592 (main): Add casts to avoid warnings
8593 if GCC considers string literals to be constants.
8594
8595 * lisp.h (fatal_error_signal): Add decl, since it's exported.
8596
8597 * dbusbind.c: Pointer signedness fixes.
8598 (xd_signature, xd_append_arg, xd_initialize):
8599 (Fdbus_call_method, Fdbus_call_method_asynchronously):

8602 (Fdbus_register_signal): Use SSDATA when the context wants char *.
8603

8659 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
8660 Assign struct members directly, instead of using BUF_BEGV etc.

8717 Improve quality of tests for time stamp overflow.
8718 For example, without this patch (encode-time 0 0 0 1 1
8719 1152921504606846976) returns the obviously-bogus value (-948597
8720 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
8721 reports time overflow. See
8722 <http://lists.gnu.org/archive/html/emacs-devel/2011-03/msg00470.html>.
8723 * deps.mk (editfns.o): Depend on ../lib/intprops.h.
