457
458 * xdisp.c (redisplay_window): If cursor row is not fully visible
459 after recentering, and scroll-conservatively is set to a large
460 number, scroll window by a few more lines to make the cursor fully
461 visible and out of scroll-margin. (Bug#10105)
462 (start_display): Don't move to the next line if the display should
463 start at a newline that is part of a display vector or an overlay
464 string. (Bug#10119)

543 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
544 Otherwise, valgrind does not work on some platforms.
545 Problem reported by Andreas Schwab in
546 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
547 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
548 is set, removing the need for VIRT_ADDRESS_VARIES.
549 (PURE_P): Use a more-efficient implementation that needs just one
550 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
551 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
552 to 4 (xorl, subq, cmpq, setbe).
553 * alloc.c (pure): Always extern now, since that's the
554 VIRT_ADDR_VARIES behavior.
555 (PURE_POINTER_P): Use a single comparison, not two, for
556 consistency with the new puresize.h.
557 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
558 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:
559 Remove VIRT_ADDR_VARIES no longer needed.

562
563 * xdisp.c (x_write_glyphs, draw_phys_cursor_glyph)
564 (erase_phys_cursor, update_window_cursor, show_mouse_face)
565 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
566 behave as if the cursor position were at the window margin.
567
568 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
569 and the cursor position is out of bounds, behave as if the cursor
570 position were at the window margin. (Bug#10075)
571
572 2011-11-18 Chong Yidong <cyd@gnu.org>
573
574 * window.c (Fwindow_combination_limit): Make first argument
575 non-optional, since it is meaningless for live windows like the
576 selected window.
577
578 2011-11-18 Dmitry Antipov <dmantipov@yandex.ru>
579
580 * keymap.c (Fwhere_is_internal): Add missing RETURN_UNGCPROs.

593 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
594
595 * xdisp.c (row_hash): New function, body extracted from
596 compute_line_metrics.
597 (compute_line_metrics): Call row_hash, instead of computing the
598 hash code inline.
599
600 * dispnew.c (verify_row_hash): Call row_hash for computing the
601 hash code of a row, instead of duplicating code from xdisp.c.
602
603 * dispextern.h (row_hash): Add prototype.
604
605 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>

640
641 2011-11-14 Eli Zaretskii <eliz@gnu.org>
642
643 * xdisp.c (display_line): Move the call to
644 highlight_trailing_whitespace before the call to
645 compute_line_metrics, since the latter needs to see the final
646 faces of all the glyphs to compute ROW's hash value.
647 Fixes assertion violations in row_equal_p. (Bug#10035)
648
649 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
650
651 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
652 just return (bug#10044).
653
654 2011-11-12 Eli Zaretskii <eliz@gnu.org>
655
656 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
657 with user-defined heap size. Bump the default size of the temacs
658 heap to 27MB, to avoid memory warning when running temacs.
659 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
660
661 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
662 current_matrix and desired_matrix. (Bug#9990)
663 (verify_row_hash) [XASSERTS]: New function.
664 (adjust_glyph_matrix, row_equal_p): Use it in xassert to verify
665 that the hash value of glyph rows is correct.

692 process_coding.
693
694 2011-11-11 Johan Bockgård <bojohan@gnu.org>

709
710 Avoid some portability problems by eschewing 'extern inline' functions.
711 The trivial performance wins aren't worth the portability hassles; see
712 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
713 et seq.
714 * dispextern.h (window_box, window_box_height, window_text_bottom_y)

766
767 2011-11-07 Kenichi Handa <handa@m17n.org>

779
780 * xmenu.c (cleanup_widget_value_tree): New function.
781 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of

788 (window_box_width, window_box_left, window_box_left_offset)
789 (window_box_right, window_box_right_offset): Declare extern.
790 Otherwise, these inline functions do not conform to C99 and
791 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
792 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
793 * intervals.c (adjust_intervals_for_insertion)
794 (adjust_intervals_for_deletion): Now extern, because otherwise the
795 extern inline functions 'offset_intervals' couldn't refer to it.
796 (static_offset_intervals): Remove.
797 (offset_intervals): Rewrite using the old contents of
798 static_offset_intervals. The old version didn't conform to C99
799 because an extern inline function contained a reference to an
800 identifier with static linkage.

821 (Fwindow_margins, Fwindow_fringes, Fwindow_scroll_bars)
822 (Fwindow_vscroll): Doc fix.

856 Initialize image_cache_refcount if GLYPH_DEBUG (Bug#9943).
857 Move terminal->reference_count++ just before making the frame official
858 (Bug#9943).

865 Move terminal->reference_count++ just before making the frame
866 official. Move initialization of image_cache_refcount and
867 dpyinfo_refcount before calling init_frame_faces (Bug#9943).
868
869 2011-11-05 Eli Zaretskii <eliz@gnu.org>
870
871 Support MSVC build with newer versions of Visual Studio.
872 * makefile.w32-in (TAGS-gmake): Don't use $(patsubst ...), as
873 Nmake barfs on that. Use $(OBJ*_c) variables instead, defined on
874 nt/gmake.defs.
875
876 * lisp.h (ENUM_BF): New macro, for enumerated types in bitfields,

923
924 * xdisp.c (note_mouse_highlight): Initialize `area'. (Bug#9947)
925
926 * w32fns.c (unwind_create_frame): If needed, free the glyph
927 matrices of the partially constructed frame. (Bug#9943)
928 * xfns.c (unwind_create_frame): Likewise.
929
930 2011-11-01 Eli Zaretskii <eliz@gnu.org>
931
932 * xdisp.c (mouse_face_from_buffer_pos): Fix a typo in a comment.
933 Don't stop backward scan on the continuation glyph, even though
934 its CHARPOS is positive.

939
940 * window.c (temp_output_buffer_show): Don't use

952 (x_error_handler): Ignore BadMatch for X_SetInputFocus for
953 HAVE_GTK3 (Bug#9869).

956 type to GDK_NOTHING so valgrind does not complain (Bug#9901).
957
958 * xterm.h (x_display_info): Add Xatom_net_wm_state_hidden (Bug#9893).
959
960 * xterm.c: Declare x_handle_net_wm_state to return int.
961 (handle_one_xevent): Check if we are iconified but don't have
962 _NET_WM_STATE_HIDDEN. If do, treat as deiconify (Bug#9893).
963 (get_current_wm_state): Return non-zero if not hidden,
964 check for _NET_WM_STATE_HIDDEN (Bug#9893).

970
971 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
972 so that this new function doesn't get optimized away by a
973 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
974
975 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
976
977 * frame.h (MOUSE_HL_INFO): Remove excess parens.

999
1000 2011-10-28 Eli Zaretskii <eliz@gnu.org>
1001
1002 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
1003 possible random value that matches one of those tested as
1004 condition to clear the mouse face.
1005
1006 2011-10-28 Chong Yidong <cyd@gnu.org>
1007

1033 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
1034 New functions.
1035 (w32font_open_internal, compute_metrics):
1036 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
1037 instead of calling the "wide" APIs directly.
1038
1039 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
1040
1041 * w32.h (syms_of_w32font): Add prototype.

1050 2011-10-27 Chong Yidong <cyd@gnu.org>
1051
1052 * process.c (make_process): Set gnutls_state to NULL.
1053
1054 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
1055 non-NULL, regardless of GNUTLS_INITSTAGE.
1056 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
1057 an error. Set process slots as soon as we allocate them.
1058
1059 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
1060
1061 2011-10-27 Chong Yidong <cyd@gnu.org>

1082
1083 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
1084
1085 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
1086
1087 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
1088

1099 * dispextern.h (struct bidi_it): New member next_en_type.
1100
1101 * bidi.c (bidi_line_init): Initialize the next_en_type member.
1102 (bidi_resolve_explicit_1): When next_en_pos is valid for the
1103 current character, check also for next_en_type being WEAK_EN.
1104 (bidi_resolve_weak): Don't enter the expensive loop if the current
1105 position is before next_en_pos. Record the bidi type of the first
1106 non-ET, non-BN character we find, in addition to its position.
1107 (bidi_level_of_next_char): Invalidate next_en_type when
1108 next_en_pos is over-stepped.
1109
1110 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
1111
1112 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
1113 * editfns.c: Rewrite current-time-zone so that it invokes
1114 the equivalent of (format-time-string "%Z") to get the time zone name.
1115 This fixes a bug when the time zone name contains characters that
1116 need converting from the system time locale to Emacs internal format.
1117 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
1118 that patch fixed format-time-string to do the conversion, but
1119 I forgot to fix current-time-zone.
1120 (format_time_string): New function, containing most of
1121 what Fformat_time_string used to contain.
1122 (Fformat_time_string): Rewrite in terms of format_time_string.
1123 This doesn't change this function's behavior.
1124 (current-time-zone): Rewrite to use format_time_string.
1125 This fixes the bug reported by Michael Schierl in
1126 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
1127 Jason Rumney's 2007-06-07 change worked around this bug, but
1128 didn't fix it.
1129 * systime.h (tzname, timezone): Remove no-longer-used declarations.
1130
1131 2011-10-19 Eli Zaretskii <eliz@gnu.org>
1132
1133 * xdisp.c (start_display): If the character at POS is displayed
1134 via a display vector, reset IT->current.dpvec_index to zero.
1135 (try_window_reusing_current_matrix): If a line ends in a display
1136 vector or the next line starts in a display vector, continue
1137 redrawing the window even though the character position of
1138 start_row was reached.
1139 (Bug#9771, part 2)
1140
1141 2011-10-18 Chong Yidong <cyd@gnu.org>
1142
1143 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
1144 with nobreak-char-display too.
1145
1146 2011-10-18 Eli Zaretskii <eliz@gnu.org>
1147
1148 Fix part 3 of bug#9771.
1149 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
1150 (bidi_resolve_neutral): Don't enter the expensive loop looking for
1151 non-neutral characters if the current character is a paragraph
1152 separator (a.k.a. Newline). This avoids running the same
1153 expensive loop twice, once when we consume the preceding newline
1154 and the other time when the line actually needs to be displayed.
1155 Avoid the loop when we see neutrals on the base embedding level
1156 following a character whose directionality is the same as the
1157 paragraph's. This avoids running the expensive loop when a line
1158 ends in a long sequence of neutrals, like control characters.
1159 Add assertion against STRONG_AL type. Slightly rearrange code
1160 that determines the type of a neutral given the first non-neutral
1161 that follows it.
1162 (bidi_level_of_next_char): Set next_en_pos to zero when
1163 invalidating its info.
1164
1165 2011-10-17 Eli Zaretskii <eliz@gnu.org>
1166
1167 * xdisp.c (push_display_prop): Determine whether to record string
1168 or buffer position by IT->string, not by IT->method. Allow
1169 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
1170 (move_it_vertically_backward): Don't look for character position
1171 immediately after the newline when in a continuation line.
1172 (Bug#9771, part 1)
1173
1174 2011-10-15 Martin Rudalics <rudalics@gmx.at>
1175
1176 * window.c (coordinates_in_window): Rewrite and delabelize
1177 vertical border check. (Bug#5357) (Bug#9618)
1178
1179 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
1180
1181 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
1182 errors in XSetWindowBorder (bug#9310).
1183
1184 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
1185
1186 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
1187 avoid crash when xmalloc overrun checking is enabled.
1188
1189 2011-10-13 Eli Zaretskii <eliz@gnu.org>
1190
1191 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
1192 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
1193 cursor motion with <left> and <right> arrow keys.
1194
1195 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
1196 some callers set that themselves.
1197
1198 2011-10-12 Eli Zaretskii <eliz@gnu.org>
1199
1200 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
1201 display string and the previous row comes from the same string and
1202 is empty. (Bug#9739) (Bug#9738)
1203
1204 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
1205
1206 * doc.c (get_doc_string): Encode file name (bug#9735).

1208 2011-10-12 Eli Zaretskii <eliz@gnu.org>
1209
1210 * bidi.c (bidi_level_of_next_char):
1211 * xdisp.c (get_visually_first_element): Remove old incorrect
1212 comments regarding the Unicode Line Separator character.
1213
1214 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
1215
1216 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
1217
1218 * alloc.c (Fgc_status): Do not access beyond zombies array
1219 boundary if nzombies > MAX_ZOMBIES.
1220 * alloc.c (dump_zombies): Add missing format specifier.
1221
1222 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
1223
1224 * xdisp.c (set_cursor_from_row): Simplify conditionals,
1225 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
1226
1227 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
1228 Some packages use them to denote characters with modifiers.
1229
1230 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
1231
1232 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
1233 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
1234 matching a pp-number. Rename parameter var to var1.
1235
1236 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
1237
1238 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
1239
1240 2011-10-08 Glenn Morris <rgm@gnu.org>
1241
1242 * callint.c (Fcall_interactively): Give a more explicit error for the
1243 'c' case with a non-character input. (Bug#8479)
1244
1245 2011-10-08 Eli Zaretskii <eliz@gnu.org>
1246
1247 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
1248 lines.
1249 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
1250 lines that are hscrolled on the left.
1251
1252 * dispnew.c (buffer_posn_from_coords): Account for a possible
1253 presence of header-line. (Bug#4426)
1254
1255 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
1256
1257 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
1258 Don't advertise functionality which we discourage or doesn't work.
1259
1260 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
1261
1262 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
1263 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
1264 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
1265 this makes Emacs dump core during garbage collection on rare
1266 occasions. sizeof is obviously inferior to offsetof here, so
1267 stick with offsetof.
1268 (GC_POINTER_ALIGNMENT): New macro.
1269 (mark_memory): Omit 3rd (offset) arg; caller changed.
1270 Don't assume EMACS_INT alignment is the same as pointer alignment.
1271
1272 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
1273
1274 * keyboard.c (read_key_sequence_remapped): New var.

1276 (command_loop_1): Use read_key_sequence's remapping directly.
1277
1278 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
1279
1280 * dired.c (file_name_completion): Don't expand file name.
1281 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
1282 before checking file name handler.
1283
1284 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
1285 they've been requested explicitly (bug#9591).
1286
1287 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
1288
1289 * keymap.c (Fsingle_key_description): Use make_specified_string
1290 instead of build_string to build string from push_key_description.
1291 (Bug#5193)
1292
1293 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
1294
1295 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
1296 This fixes a Y2038 bug on 64-bit hosts.
1297 * buffer.c (reset_buffer):
1298 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
1299 (Fclear_buffer_auto_save_failure):
1300 Use 0, not -1, to represent an unset failure time, since time_t
1301 might not be signed.
1302
1303 Remove dependency on glibc malloc internals.
1304 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
1305 Move back here from lisp.h, but with their new implementations.
1306 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
1307 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
1308 * charset.c (charset_table_init): New static var.
1309 (syms_of_charset): Use it instead of xmalloc. This removes a
1310 dependency on glibc malloc internals. See Eli Zaretskii's comment in
1311 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
1312 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
1313 Move back to alloc.c.
1314 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
1315 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
1316
1317 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
1318
1319 * nsterm.m (windowDidResize): Call x_set_window_size only when
1320 ns_in_resize is true. Otherwise set pixelwidth/height and
1321 call change_frame_size (Bug#9628).
1322
1323 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
1324
1325 Port --enable-checking=all to Fedora 14 x86-64.
1326 * charset.c (syms_of_charset): Also account for glibc malloc's
1327 internal overhead when calculating the initial malloc maximum.
1328
1329 Port --enable-checking=all to Fedora 14 x86.
1330 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
1331 Move to lisp.h.
1332 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
1333 (overrun_check_realloc, overrun_check_free):
1334 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
1335 That way, xmalloc returns a properly-aligned pointer even if
1336 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
1337 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
1338 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
1339 into account when calculating the initial malloc maximum.
1340 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
1341 Move here from alloc.c, so that charset.c can use it too.
1342 Properly align; the old code wasn't right for common 32-bit hosts
1343 when configured with --enable-checking=all.
1344 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
1345 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
1346
1347 2011-09-29 Eli Zaretskii <eliz@gnu.org>

1350 use EDOM.
1351
1352 2011-09-28 Eli Zaretskii <eliz@gnu.org>
1353
1354 * xdisp.c (compute_display_string_end): If there's no display
1355 string at CHARPOS, return -1.
1356
1357 * bidi.c (bidi_fetch_char): When compute_display_string_end
1358 returns a negative value, treat the character as a normal
1359 character not covered by a display string. (Bug#9624)
1360
1361 2011-09-28 Juanma Barranquero <lekktu@gmail.com>

1363 * lread.c (Fread_from_string): Fix typo in docstring.
1364
1365 2011-09-27 Eli Zaretskii <eliz@gnu.org>
1366
1367 * xdisp.c (handle_invisible_prop): If invisible text ends on a
1368 newline, reseat the iterator instead of bidi-iterating there one
1369 character at a time. (Bug#9610)
1370 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
1371 TO_CHARPOS if the bidi iterator is at base embedding level.
1372
1373 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>

1401
1402 2011-09-24 Eli Zaretskii <eliz@gnu.org>
1403
1404 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
1405 Default value is now t. Doc fix.
1406
1407 * indent.c (Fvertical_motion): Compute and apply the overshoot
1408 logic when moving up, not only when moving down. Fix the
1409 confusing name and values of the it_overshoot_expected variable;
1410 logic changes accordingly. (Bug#9254) (Bug#9549)
1411
1412 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
1413 CHARPOS is covered by a display string which includes newlines.
1414 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
1415 is covered by a display string with embedded newlines.

1424 2011-09-24 Jim Meyering <meyering@redhat.com>
1425
1426 do not ignore write error for any output size
1427 The previous change was incomplete.
1428 While it makes emacs --batch detect the vast majority of stdout
1429 write failures, errors were still ignored whenever the output size is
1430 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
1431 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
1432 && echo FAIL: ignored write error
1433 FAIL: ignored write error
1434 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
1435 && echo FAIL: ignored write error
1436 FAIL: ignored write error
1437 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
1438
1439 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
1440
1441 * emacs.c (Fkill_emacs): In noninteractive mode exit
1442 non-successfully if a write error occurred on stdout. (Bug#9574)
1443
1444 2011-09-21 Eli Zaretskii <eliz@gnu.org>
1445
1446 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
1447 the xassert test.
1448
1449 * dispextern.h (struct it): Update the comment documenting what
1450 can it->OBJECT be.
1451
1452 2011-09-20 Eli Zaretskii <eliz@gnu.org>
1453
1454 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
1455 a display string, extend search for cursor position to end of row.
1456 (find_row_edges): If the row ends in a newline from a display
1457 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
1458 Handle the case of a display string with multiple newlines.
1459 (Fcurrent_bidi_paragraph_direction): Fix search for previous
1460 non-empty line. Fixes confusing cursor motion with arrow keys at
1461 the beginning of a line that starts with whitespace.
1462
1463 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
1464

1472
1473 2011-09-18 Eli Zaretskii <eliz@gnu.org>
1474
1475 * xdisp.c (display_line): Record maximum and minimum buffer
1476 positions even if no glyphs were produced (e.g., by a zero-width
1477 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
1478 buffer positions that will be removed from the glyph row because
1479 they don't fit.
1480 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
1481 column is beyond frame width: don't subtract 1 "pixel" when
1482 computing width of the stretch.
1483 (reseat_at_next_visible_line_start): Undo the change made on
1484 2011-09-17 that saved paragraph information and restored it after
1485 the call to `reseat'. (Bug#9545)
1486
1487 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
1488
1489 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
1490 and turn window cursor on if cleared (Bug#9415).
1491
1492 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
1493
1494 * search.c (boyer_moore): Take unibyte characters from pattern

1502
1503 Fix minor problem found by static checking.
1504 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
1505 initialized, to pacify gcc -Wuninitialized.
1506
1507 * fileio.c: Report proper errno when syscall falls.
1508 (Finsert_file_contents): Save and restore errno,
1509 so that report_file_error outputs the correct diagnostic.
1510 (Fwrite_region) [CLASH_DETECTION]: Likewise.
1511
1512 2011-09-18 Eli Zaretskii <eliz@gnu.org>

1520
1521 2011-09-17 Eli Zaretskii <eliz@gnu.org>
1522
1523 * xdisp.c (reseat_at_next_visible_line_start): Keep information
1524 about the current paragraph and restore it after the call to reseat.
1525
1526 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
1527 (bidi_find_paragraph_start): Search back for paragraph beginning
1528 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
1529 (bidi_move_to_visually_next): Only trigger paragraph-related
1530 computations when the last character is a newline or at EOB, not
1531 just any NEUTRAL_B. (Bug#9470)
1532
1533 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
1534 truncated lines if point is covered by a display string. (Bug#9524)
1535
1536 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
1537
1538 * xselect.c: Relax test for outgoing X longs (Bug#9498).
1539 (cons_to_x_long): New function.
1540 (lisp_data_to_selection_data): Use it. Correct the test for
1541 short-versus-long data; it was negated. Break out of vector
1542 loop, for efficiency, when a long datum is discovered.
1543
1544 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
1545
1546 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
1547
1548 2011-09-16 Eli Zaretskii <eliz@gnu.org>
1549
1550 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
1551 GCC PR/17406) by declaring this function with external scope.
1552
1553 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
1554
1555 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
1556 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
1557
1558 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
1559

1573
1574 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).

1583 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
1584
1585 Remove unused external symbols.

1592
1593 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
1594
1595 * xselect.c: Use signed conversions more consistently (Bug#9498).
1596 (selection_data_to_lisp_data): Assume incoming selection data are
1597 signed integers, not unsigned. This is to be consistent with
1598 outgoing selection data, which was modified to use signed integers
1599 in as part of the fix to Bug#9196 in response to Jan D.'s comment
1600 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
1601 expects long, not unsigned long.

1613 2011-09-12 Eli Zaretskii <eliz@gnu.org>
1614
1615 * indent.c (compute_motion): Process display vector front to back

1617
1618 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>

1623
1624 * minibuf.c (Fread_from_minibuffer): Doc fix.
1625
1626 2011-09-11 Eli Zaretskii <eliz@gnu.org>
1627
1628 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from

1630
1631 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
1632
1633 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
1634 value for non-existent files.
1635
1636 2011-09-11 Eli Zaretskii <eliz@gnu.org>
1637
1638 * fileio.c (Finsert_file_contents): If the file cannot be opened,
1639 set its "size" to -1. This will set the modtime_size field of
1640 the corresponding buffer to -1, which is what
1641 verify-visited-file-modtime expects for files that do not exist.
1642 (Bug#9139)
1643
1644 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
1645
1646 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
1647 here ...
1648 * lisp.h: ... from here. push_key_description is no longer
1649 defined in keyboard.c, so its declaration should not be in
1650 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
1651 logically belongs with push_key_description.
1652
1653 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
1654
1655 * buffer.h: Include <sys/types.h> instead of <time.h>.

1697
1698 isnan: Fix porting problem to Solaris 10 with bundled gcc.
1699 Without this fix, the command to link temacs failed due to an
1700 undefined symbol __builtin_isnan. This is because
1701 /usr/include/iso/math_c99.h #defines isnan(x) to
1702 __builtin_isnan(x), but the bundled gcc, which identifies itself
1703 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
1704 a __builtin_isnan.
1705 * floatfns.c (isnan): #undef, and then #define to a clone of
1706 what's in data.c.
1707 (Fisnan): Always define, since it's always available now.
1708 (syms_of_floatfns): Always define isnan at the Lisp level.
1709
1710 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>

1715
1716 * fileio.c: Fix bugs with large file offsets (Bug#9428).
1717 The previous code assumed that file offsets (off_t values) fit in
1718 EMACS_INT variables, which is not true on typical 32-bit hosts.
1719 The code messed up by falsely reporting buffer overflow in cases
1720 such as (insert-file-contents "big" nil 1 2) into an empty buffer
1721 when "big" contains more than 2**29 bytes, even though this
1722 inserts just one byte and does not overflow the buffer.
1723 (Finsert_file_contents): Store file offsets as off_t
1724 values, not as EMACS_INT values. Check for overflow when
1725 converting between EMACS_INT and off_t. When checking for
1726 buffer overflow or for overlap, take the offsets into account.
1727 Don't use EMACS_INT for small values where int suffices.
1728 When checking for overlap, fix a typo: ZV was used where
1729 ZV_BYTE was intended.
1730 (Fwrite_region): Don't assume off_t fits into 'long'.
1731 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.

1733 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
1734
1735 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
1736
1737 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
1738
1739 sprintf-related integer and memory overflow issues (Bug#9412).
1740
1741 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
1742 (esprintf, exprintf, evxprintf): New functions.
1743 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
1744 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
1745 (modify_event_symbol): Do not assume that the length of
1746 name_alist_or_stem is safe to alloca and fits in int.
1747 (Fexecute_extended_command): Likewise for function name and binding.
1748 (Frecursion_depth): Wrap around reliably on integer overflow.
1749 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
1750 since some callers pass EMACS_INT values.
1751 (Fsingle_key_description): Don't crash if symbol name contains more
1752 than MAX_ALLOCA bytes.
1753 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
1754 (get_minibuffer): Arg is now EMACS_INT, not int.
1755 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
1756 (esprintf, exprintf, evxprintf): New decls.
1757 * window.h (command_loop_level, minibuf_level): Reflect API changes.
1758
1759 * dbusbind.c (signature_cat): New function.
1760 (xd_signature, Fdbus_register_signal):
1761 Do not overrun buffer; instead, report string overflow.
1762
1763 * dispnew.c (add_window_display_history): Don't overrun buffer.
1764 Truncate instead; this is OK since it's just a log.
1765
1766 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
1767 even if the time zone offset is outlandishly large.
1768 Don't mishandle offset == INT_MIN.
1769
1770 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
1771 when creating daemon; the previous buffer-overflow check was incorrect.
1772
1773 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
1774 which has the guts of the old verror function.
1775
1776 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
1777 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
1778
1779 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
1780 (font_unparse_xlfd): Don't blindly alloca long strings.
1781 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
1782 fits in int, when using sprintf. Use single snprintf to count
1783 length of string rather than counting it via multiple sprintfs;
1784 that's simpler and more reliable.
1785 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
1786 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
1787 sprintf, in case result does not fit in int.
1788
1789 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
1790 (fontset_from_font): Print it.
1791
1792 * frame.c (tty_frame_count): Now printmax_t, not int.
1793 (make_terminal_frame, set_term_frame_name): Print it.
1794 (x_report_frame_params): In X, window IDs are unsigned long,
1795 not signed long, so print them as unsigned.
1796 (validate_x_resource_name): Check for implausibly long names,
1797 and don't assume name length fits in 'int'.
1798 (x_get_resource_string): Don't blindly alloca invocation name;
1799 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
1800 not fit in int.
1801
1802 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
1803 (xg_check_special_colors, xg_set_geometry):
1804 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
1805
1806 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
1807 Use esprintf, not sprintf, in case result does not fit in int.
1808
1809 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
1810 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
1811 it as a large positive number.
1812 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
1813 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
1814
1815 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
1816 in case result does not fit in int.
1817
1818 * print.c (float_to_string): Detect width overflow more reliably.
1819 (print_object): Make sprintf buffer a bit bigger, to avoid potential
1820 buffer overrun. Don't assume list length fits in 'int'. Treat
1821 print length of 0 as 0, not as infinity; to be consistent with other
1822 uses of print length in this function. Don't overflow print length
1823 index. Don't assume hash table size fits in 'long', or that
1824 vectorlike size fits in 'unsigned long'.
1825
1826 * process.c (make_process): Use printmax_t, not int, to format
1827 process-name gensyms.
1828
1829 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
1830
1831 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
1832 to avoid potential buffer overrun.
1833
1834 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
1835 if X resource line is longer than 512 bytes.
1836
1837 * xfns.c (x_window): Make sprintf buffer a bit bigger
1838 to avoid potential buffer overrun.
1839
1840 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
1841
1842 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
1843
1844 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
1845
1846 Integer overflow fixes for scrolling, etc.
1847 Without these, Emacs silently mishandles large integers sometimes.
1848 For example, "C-u 4294967297 M-x recenter" was treated as if
1849 it were "C-u 1 M-x recenter" on a typical 64-bit host.
1850
1851 * xdisp.c (try_window_id): Check Emacs fixnum range before
1852 converting to 'int'.
1853
1854 * window.c (window_scroll_line_based, Frecenter):
1855 Check that an Emacs fixnum is in range before assigning it to 'int'.
1856 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
1857 values converted from Emacs fixnums.
1858 (Frecenter): Don't wrap around a line count if it is out of 'int'
1859 range; instead, treat it as an extreme value.
1860 (Fset_window_configuration, compare_window_configurations):
1861 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
1862
1863 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
1864 that can exceed INT_MAX. Check that EMACS_INT value is in range
1865 before assigning it to the (possibly-narrower) index.
1866 (match_limit): Don't assume that a fixnum can fit in 'int'.
1867
1868 * print.c (print_object): Use ptrdiff_t, not int, for index that can
1869 exceed INT_MAX.
1870
1871 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
1872 (Fvertical_motion): Don't wrap around LINES values that don't fit
1873 in 'int'. Instead, treat them as extreme values. This is good
1874 enough for windows, which can't have more than INT_MAX lines anyway.
1875
1876 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
1877
1878 * Require libxml/parser.h to avoid compilation warning.
1879
1880 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
1881
1882 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
1883 since this reportedly can destroy thread storage.
1884
1885 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
1886
1887 * syntax.c (find_defun_start): Update all cache variables if
1888 exiting early (Bug#9401).
1889
1890 2011-08-30 Eli Zaretskii <eliz@gnu.org>
1891
1892 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
1893
1894 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
1895 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
1896 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
1897
1898 * term.c (tty_append_glyph): New function.
1899 (produce_stretch_glyph): Static function and its prototype deleted.
1900
1901 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
1902 Add prototypes.
1903
1904 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
1905
1906 * image.c (parse_image_spec): Check for nonnegative, not for positive,
1907 when checking :margin (Bug#9390).
1908 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
1909 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
1910 so that the name doesn't mislead. All uses changed.
1911
1912 2011-08-28 Johan Bockgård <bojohan@gnu.org>
1913
1914 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
1915 set_tty_hooks.
1916
1917 2011-08-27 Eli Zaretskii <eliz@gnu.org>
1918
1919 * xdisp.c (move_it_to): Don't bail out early when reaching
1920 position beyond to_charpos, if we are scanning backwards.
1921 (move_it_vertically_backward): When DY == 0, make sure we get to
1922 the first character in the line after the newline.
1923
1924 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
1925
1926 * ccl.c: Improve and simplify overflow checking (Bug#9196).
1927 (ccl_driver): Do not generate an out-of-range pointer.
1928 (Fccl_execute_on_string): Remove unnecessary check for
1929 integer overflow, noted by Stefan Monnier in
1930 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
1931 Remove a FIXME that didn't need fixing.
1932 Simplify the newly-introduced buffer reallocation code.
1933
1934 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
1935
1936 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
1937
1938 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
1939
1940 Integer and memory overflow issues (Bug#9196).
1941
1942 * doc.c (get_doc_string): Rework so that
1943 get_doc_string_buffer_size is the actual buffer size, rather than
1944 being 1 less than the actual buffer size; this makes xpalloc more
1945 convenient.
1946
1947 * image.c (x_allocate_bitmap_record, cache_image):
1948 * xselect.c (Fx_register_dnd_atom):
1949 Simplify previous changes by using xpalloc.
1950
1951 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
1952 since either will do and ptrdiff_t is convenient with xpalloc.
1953
1954 * charset.c (charset_table_size)
1955 (struct charset_sort_data.priority): Now ptrdiff_t.
1956 (charset_compare): Don't overflow if priorities differ greatly.
1957 (Fsort_charsets): Don't assume list length fits in int.
1958 Check for size-calculation overflow when allocating sort data.
1959 (syms_of_charset): Allocate an initial charset table that is
1960 just under 64 KiB, to avoid problems with glibc malloc and mmap.
1961
1962 * cmds.c (internal_self_insert): Check for size-calculation overflow.
1963
1964 * composite.h (struct composition.glyph_len): Now int, not unsigned.
1965 The actual value is always <= INT_MAX, and leaving it unsigned made
1966 overflow checking harder.
1967
1968 * dispextern.h (struct glyph_matrix.rows_allocated)
1969 (struct face_cache.size): Now ptrdiff_t, for convenience in use
1970 with xpalloc. The values are still always <= INT_MAX.
1971
1972 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
1973
1974 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
1975 (SAFE_NALLOCA): New macro.
1976
1977 * region-cache.c (struct boundary.pos, find_cache_boundary)
1978 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
1979 (set_cache_region, invalidate_region_cache)
1980 (revalidate_region_cache, know_region_cache, region_cache_forward)
1981 (region_cache_backward, pp_cache):
1982 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
1983 so that ptrdiff_t * can be passed to xpalloc.
1984 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
1985 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
1986 (pp_cache): Don't assume cache_len fits in int.
1987 * region-cache.h: Adjust extern decls to match.
1988
1989 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
1990 EMACS_INT, since either will do, for xpalloc.
1991
1992 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
1993 (xnmalloc, xnrealloc, xpalloc): New functions.
1994
1995 * bidi.c (bidi_shelve_header_size): New constant.
1996 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
1997 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
1998
1999 * bidi.c (bidi_cache_shrink):
2000 * buffer.c (overlays_at, overlays_in, record_overlay_string)
2001 (overlay_strings):
2002 Don't update size of array until after memory allocation succeeds,
2003 because xmalloc/xrealloc may not return.
2004 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
2005 now that we have proper integer overflow checking.
2006 (record_overlay_string, overlay_strings): Catch overflows when
2007 calculating size of overlay_str_buf.
2008
2009 * callproc.c (Fcall_process): Check for size overflow when
2010 calculating size of args2.
2011 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
2012 Normally we prefer signed values, but sticking with ptrdiff_t would
2013 require adding more-complicated checks.
2014
2015 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
2016 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
2017 Redo buffer-overflow calculations to avoid integer overflow.
2018 Add a FIXME comment where memory seems to be over-allocated.
2019
2020 * character.c (Fstring): Check for size-calculation overflow.
2021
2022 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
2023 unnecessary integer overflow. Check for size overflow.
2024 (encode_coding_object): Don't update size until xmalloc succeeds.
2025
2026 * composite.c (get_composition_id): Check for overflow in glyph
2027 length calculations.
2028
2029 Integer and memory overflow fixes for display code.
2030 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
2031 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
2032 (scrolling_window): Check for overflow in size calculations.
2033 (line_draw_cost, realloc_glyph_pool, add_row_entry):
2034 Don't assume glyph table len fits in int.

2036 (row_table_size): Now ptrdiff_t, not int.
2037 (scrolling_window): Avoid overflow in size calculations.
2038 Don't update size until allocation succeeds.
2039 * fns.c (concat): Check for overflow in size calculations.
2040 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
2041 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
2042 (NEXT_ALMOST_PRIME_LIMIT): New constant.
2043
2044 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
2045 (get_doc_string): Check for size calculation overflow.
2046 Don't update size until allocation succeeds.
2047 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
2048 EMACS_INT, where ptrdiff_t will do.
2049 (Fsubstitute_command_keys): Check for string overflow.
2050
2051 * editfns.c (set_time_zone_rule): Don't assume environment length
2052 fits in int.
2053 (message_length): Now ptrdiff_t, not int.
2054 (Fmessage_box): Don't update size until allocation succeeds.
2055 Don't assume message length fits in int.
2056 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
2057
2058 * emacs.c (main): Do not reallocate argv, since there is a null at
2059 the end that can be overwritten, and this way there's no need to
2060 worry about size-calculation overflow.
2061 (sort_args): Check for size-calculation overflow.
2062
2063 * eval.c (init_eval_once, grow_specpdl): Don't update size until
2064 alloc succeeds.
2065 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
2066
2067 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
2068 (x_set_scroll_bar_width, x_figure_window_size):
2069 Check for integer overflow.
2070 (x_set_alpha): Do not assume XINT fits in int.
2071
2072 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
2073 This is for the members text_lines, text_cols, total_lines, total_cols,
2074 where the system imposes an 'int' limit.
2075
2076 * fringe.c (Fdefine_fringe_bitmap):
2077 Don't update size until alloc works.
2078
2079 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
2080 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
2081
2082 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
2083 Check for size-calculation overflow.
2084 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
2085 do, as we prefer signed integers.
2086 (id_to_widget.max_size, id_to_widget.used)
2087 (xg_store_widget_in_map, xg_remove_widget_from_map)
2088 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
2089 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
2090 Use and return ptrdiff_t, not int.
2091 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
2092 * gtkutil.h: Change prototypes to match the above.
2093
2094 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
2095 are duplicate now that they've been promoted to lisp.h.
2096 (x_allocate_bitmap_record, x_alloc_image_color)
2097 (make_image_cache, cache_image, xpm_load):
2098 Don't update size until alloc is done.
2099 (xpm_load, lookup_rgb_color, lookup_pixel_color, x_to_xcolors)
2100 (x_detect_edges):
2101 Check for size calculation overflow.
2102 (ct_colors_allocated_max): New constant.
2103 (x_to_xcolors, x_detect_edges): Reorder multiplicands to avoid
2104 overflow.
2105
2106 * keyboard.c (read_char, menu_bar_items, tool_bar_items)
2107 (read_char_x_menu_prompt, read_char_minibuf_menu_width)
2108 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
2109 Use ptrdiff_t, not int, to count maps.
2110 (read_char_minibuf_menu_prompt): Check for overflow in size
2111 calculations. Don't update size until allocation succeeds.
2112 Redo calculations to avoid overflow.
2113 * keyboard.h: Change prototypes to match the above.
2114
2115 * keymap.c (cmm_size, current_minor_maps): Use ptrdiff_t, not int,
2116 to count maps.
2117 (current_minor_maps): Check for size calculation overflow.
2118 * keymap.h: Change prototypes to match the above.
2119
2120 * lread.c (read1, init_obarray): Don't update size until alloc done.
2121
2122 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.
2123 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.
2124
2125 * nsterm.h (struct ns_color_table.size, struct ns_color_table.avail):
2126 Now ptrdiff_t, not int.
2127 * nsterm.m (ns_index_color): Use ptrdiff_t, not int, for table indexes.
2128 (ns_draw_fringe_bitmap): Rewrite to avoid overflow.
2129
2130 * process.c (Fnetwork_interface_list): Check for overflow
2131 in size calculation.
2132
2133 * region-cache.c (move_cache_gap): Check for size calculation overflow.
2134
2135 * scroll.c (do_line_insertion_deletion_costs): Check for size calc
2136 overflow. Don't bother calling xmalloc when xrealloc will do.
2137
2138 * search.c (Freplace_match): Check for size calculation overflow.
2139 (Fset_match_data): Don't assume list lengths fit in 'int'.
2140
2141 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
2142 for command line length. Do not attempt to address one before the
2143 beginning of an array, as that's not portable.
2144
2145 * term.c (max_frame_lines): Remove; unused.
2146 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
2147 not int.
2148 (encode_terminal_code, calculate_costs): Check for size
2149 calculation overflow.
2150 (encode_terminal_code): Use ptrdiff_t, not int, to record glyph
2151 table lengths and related sizes. Don't update size until alloc
2152 done. Redo calculations to avoid overflow.
2153 (calculate_costs): Don't bother calling xmalloc when xrealloc will do.
2154
2155 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
2156 subtracting pointers.
2157 (gobble_line): Check for overflow more carefully. Don't update size
2158 until alloc done.
2159
2160 * tparam.c (tparam1): Use ptrdiff_t, not int, for sizes.
2161 Don't update size until alloc done.
2162 Redo size calculations to avoid overflow.
2163 Check for size calculation overflow.

2171 Use ptrdiff_t, not int, for sizes.
2172 (Finternal_make_lisp_face, cache_face):
2173 Check for size calculation overflow.
2174 (cache_face): Treat size calculation overflows as if they were
2175 memory exhaustion (the usual treatment), rather than aborting.
2176
2177 * xfns.c (x_encode_text, x_set_name_internal)
2178 (Fx_change_window_property): Use ptrdiff_t, not int, to count
2179 sizes, since they can exceed INT_MAX in size. Check for size
2180 calculation overflow.
2181
2182 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
2183 (xg_select): Check for size calculation overflow.
2184 Don't update size until alloc done.
2185
2186 * xrdb.c (get_environ_db): Don't assume path length fits in int,
2187 as sprintf is limited to int lengths.
2188
2189 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
2190 (X_LONG_MIN): New macros.
2191 Use them to make the following changes clearer.
2192 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
2193 This change doesn't affect the value now, but it may help remind
2194 future maintainers not to raise the value too much later.
2195 (SELECTION_QUANTUM): Remove, replacing with ...
2196 (selection_quantum): ... new function, which avoids overflow.
2197 All uses changed.
2198 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
2199 assumption that selection length fits in 'int'.
2200 (x_reply_selection_request, x_handle_selection_request)
2201 (x_get_window_property, receive_incremental_selection)
2202 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
2203 (lisp_data_to_selection_data, clean_local_selection_data):
2204 Use ptrdiff_t, not int, to record length of selection.
2205 (x_reply_selection_request, x_get_window_property)
2206 (receive_incremental_selection, x_property_data_to_lisp):
2207 Redo calculations to avoid overflow.
2208 (x_reply_selection_request): When sending hint, ceiling it at
2209 X_LONG_MAX rather than relying on wraparound overflow to send
2210 something.
2211 (x_get_window_property, receive_incremental_selection)
2212 (lisp_data_to_selection_data, x_property_data_to_lisp):
2213 Check for size-calculation overflow.
2214 (x_get_window_property, receive_incremental_selection)
2215 (lisp_data_to_selection_data, Fx_register_dnd_atom):
2216 Don't store size until memory allocation succeeds.
2217 (x_get_window_property): Plug memory leak on memory exhaustion.
2218 Don't double-block input; malloc is safe here. Don't assume 2**34
2219 - 4 fits in unsigned long. Add an xassert to check
2220 XGetWindowProperty overflow. Be more careful about overflow
2221 calculations, and distinguish size from memory overflow better.
2222 (receive_incremental_selection): When tracing, don't assume
2223 unsigned int is less than INT_MAX.
2224 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
2225 harmful) conversions of unsigned short to int.
2226 (lisp_data_to_selection_data): Don't assume that integers
2227 in the range -65535 through -1 fit in an X unsigned short.
2228 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
2229 result parameters unless successful. Rely on cons_to_unsigned
2230 to report problems with elements; the old code wasn't right anyway.
2231 (x_check_property_data): Check for int overflow; we cannot use
2232 a wider type due to X limits.
2233 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
2234
2235 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.
2236
2237 * xterm.c (x_color_cells, x_send_scrollbar_event, handle_one_xevent)
2238 (x_term_init): Check for size calculation overflow.
2239 (x_color_cells): Don't store size until memory allocation succeeds.
2240 (handle_one_xevent): Use ptrdiff_t, not int, for byte counts.
2241 Don't assume alloca size is less than MAX_ALLOCA.
2242 (x_term_init): Don't assume length fits in int (sprintf is limited
2243 to int size).
2244
2245 Use ptrdiff_t for composition IDs.
2246 * character.c (lisp_string_width):
2247 * composite.c (composition_table_size, n_compositions)
2248 (get_composition_id, composition_gstring_from_id):

2264 * image.c (xpm_get_color_table_h):
2265 * lisp.h (hash_lookup, hash_put):
2266 * minibuf.c (Ftest_completion):
2267 Use ptrdiff_t for hash table indexes, not int (which is too
2268 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
2269 32-bit --with-wide-int hosts).
2270
2271 * charset.c (Fdefine_charset_internal): Check for integer overflow.
2272 Add a FIXME comment about memory leaks.
2273 (syms_of_charset): Don't assume xmalloc returns.
2274
2275 Don't assume that stated character widths fit in int.
2276 * character.c (Fchar_width, c_string_width, lisp_string_width):
2277 * character.h (CHAR_WIDTH):
2278 * indent.c (MULTIBYTE_BYTES_WIDTH):
2279 Use sanitize_char_width to avoid undefined and/or bad behavior
2280 with outlandish widths.
2281 * character.h (sanitize_tab_width): Rename from sanitize_width,
2282 now that we have two such functions. All uses changed.
2283 (sanitize_char_width): New inline function.
2284
2285 Don't assume that tab-width fits in int.
2286 * character.h (sanitize_width): New inline function.
2287 (SANE_TAB_WIDTH): New macro.
2288 (ASCII_CHAR_WIDTH): Use it.

2295
2296 * charset.c (read_hex): New arg OVERFLOW. All uses changed.
2297 Remove unreachable code.
2298 (read_hex, load_charset_map_from_file): Check for integer overflow.
2299
2300 * xterm.c: don't go over XClientMessageEvent limit
2301 (scroll_bar_windows_size): Now ptrdiff_t, as we prefer signed.
2302 (x_send_scroll_bar_event): Likewise. Check that the size does not
2303 exceed limits imposed by XClientMessageEvent, as well as the usual
2304 ptrdiff_t and size_t limits.
2305
2306 * keyboard.c: Overflow, signedness and related fixes.
2307 (make_lispy_movement): Use same integer type in forward decl
2308 that is used in the definition.
2309 (read_key_sequence, keyremap_step):
2310 Change bufsize argument back to int, undoing my 2011-03-30 change.
2311 We prefer signed types, and int is wide enough here.
2312 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
2313 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
2314 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
2315 length, not size_t. Use ptrdiff_t for index, not int.
2316 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
2317 possibility of integer overflow.
2318
2319 Overflow, signedness and related fixes for images.

2328 * nsmenu.m (update_frame_tool_bar):
2329 * xdisp.c (calc_pixel_width_or_height):
2330 * xfns.c (image_cache_refcount):
2331 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
2332 on typical 64-bit hosts.

2338 when the callers expect that.
2339 (image_ascent): Redo ascent calculation to avoid int overflow.
2340 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
2341 (lookup_image): Remove unnecessary tests.
2342 (xbm_image_p): Locals are now of int, not EMACS_INT,
2343 since parse_image_check makes sure they fit into int.
2344 (png_load, gif_load, svg_load_image):
2345 Prefer int to unsigned where either will do.
2346 (tiff_handler): New function, combining the cores of the
2347 old tiff_error_handler and tiff_warning_handler.
2348 This function is rewritten to use vsnprintf and thereby avoid
2349 stack buffer overflows. It uses only the features of vsnprintf
2350 that are common to both POSIX and native Microsoft.
2351 (tiff_error_handler, tiff_warning_handler): Use it.
2352 (tiff_load, gif_load, imagemagick_load_image):
2353 Don't assume :index value fits in 'int'.
2354 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
2355 (imagemagick_load_image): Check that crop parameters fit into
2356 the integer types that MagickCropImage accepts. Don't assume
2357 Vimagemagick_render_type has a nonnegative value. Don't assume
2358 size_t fits in 'long'.
2359 (gs_load): Use printmax_t to print the widest integers possible.

2368
2369 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
2370 the display spec is of the form `(space ...)'.
2371 (handle_display_spec): Return the value returned by
2372 handle_single_display_spec, not just 1 or zero.
2373 (handle_single_display_spec): If the display spec is of the form
2374 `(space ...)', and specifies display in the text area, return 2
2375 rather than 1.
2376 (try_cursor_movement): Check for the need to scroll more
2377 accurately, and prefer exact match for point under bidi.
2378 Don't advance `row' beyond the last row of the window.
2379
2380 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
2381 into disp_prop; all users changed.
2382

2396 buffers, return left-to-right.
2397 (set_cursor_from_row): Consider candidate row a win if its glyph
2398 represents a newline and point is on that newline. Fixes cursor
2399 positioning on the newline at EOL of R2L text within L2R
2400 paragraph, and vice versa.
2401 (try_cursor_movement): Check continued rows, in addition to
2402 continuation rows. Fixes unwarranted scroll when point enters a
2403 continued line of R2L text within an L2R paragraph, or vice versa.
2404 (cursor_row_p): Consider the case of point being equal to
2405 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
2406 from the end of a short line to the beginning of a continued line
2407 of R2L text within L2R paragraph.
2408 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
2409 composed characters.
2410

2412 (bidi_cache_iterator_state): Update the disp_pos and disp_prop_p
2413 members.

2430
2431 * xdisp.c (redisplay_window): When computing centering_position,
2432 account for the height of the header line. (Bug#8874)
2433
2434 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
2435 instead of CHAR_TO_BYTE. Fixes a crash when a completion
2436 candidate is selected by the mouse, and that candidate has a
2437 composed character under the mouse.
2438
2439 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
2440 coordinates reported by pos-visible-in-window-p for a composed
2441 character in column zero.

2447 2011-08-22 Eli Zaretskii <eliz@gnu.org>
2448
2449 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
2450 consider it a hit if to_charpos is anywhere in the range of the
2451 composed buffer positions.
2452
2453 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
2454
2455 * image.c (gif_load): Don't assume that each subimage has the same
2456 dimensions as the base image. Handle disposal method that is
2457 "undefined" by the gif spec (Bug#9335).
2458
2459 2011-08-20 Chong Yidong <cyd@stupidchicken.com>

2473 with a composed character.
2474
2475 2011-08-18 Eli Zaretskii <eliz@gnu.org>
2476
2477 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
2478 character bidirectional type, use STRONG_L instead. Fixes crashes
2479 in a buffer produced by `describe-categories'.
2480
2481 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
2482 members before the level stack, so they would be saved and
2483 restored when copying iterator state. Fixes incorrect reordering
2484 around TABs covered by display properties.
2485
2486 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
2487

2560 ppos_it. Fixes vertical cursor motion when line beginning is
2561 covered by an image. (Bug#9296)
2562
2563 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
2564
2565 * nsterm.h (ns_run_ascript): Declare.
2566 (NSAPP_DATA2_RUNASSCRIPT): Define.
2567
2568 * nsfns.m (as_script, as_result, as_status): New static variables.
2569 (ns_run_ascript): New function.
2570 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
2571 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
2572 the event loop. Get status from as_status (Bug#7276).
2573
2574 * nsterm.m (sendEvent): If event is NSApplicationDefined and
2575 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
2576 the event loop (Bug#7276).
2577
2578 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
2579
2580 * gnutls.c (QCgnutls_bootprop_priority)
2581 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
2582 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
2583 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
2584 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
2585 (QCgnutls_bootprop_verify_hostname_error)
2586 (QCgnutls_bootprop_callbacks_verify): Rename from
2587 Qgnutls_bootprop_..., all uses changed.
2588
2589 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
2590 uses changed.
2591
2592 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
2593
2594 * xfaces.c (Qframe_set_background_mode): Now static.
2595 * dispextern.h (Qframe_set_background_mode): Remove decl.
2596
2597 * process.c (Fnetwork_interface_info): Declare local only if needed.
2598
2599 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
2600
2601 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
2602 (Fnetwork_interface_list): Allocate in increments of bytes instead
2603 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
2604 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
2605 sockaddr.
2606 (struct ifflag_def): notrailers is smart on OSX.
2607 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
2608 Get hardware address with getifaddrs if available.
2609
2610 2011-08-12 Eli Zaretskii <eliz@gnu.org>
2611
2612 * xdisp.c (iterate_out_of_display_property): xassert that
2613 IT->position is set to within IT->object's boundaries. Break from
2614 the loop as soon as EOB is reached; avoids infloops in redisplay
2615 when IT->position is set up wrongly due to some bug.
2616 Set IT->current to match the bidi iterator unconditionally.
2617 (push_display_prop): Allow GET_FROM_STRING as IT->method on
2618 entry. Force push_it to save on the stack the current
2619 buffer/string position, to be restored by pop_it. Fix flags in
2620 the iterator structure wrt the object coming from a display
2621 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
2622 properties. (Bug#9284)
2623
2624 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
2625
2626 * fontset.c (fontset_get_font_group): Add proper type checks.
2627 (Bug#9172)
2628
2629 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2630
2631 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
2632 and LC_VERSION_MIN_MACOSX.
2633 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
2634 (dump_it) [LC_FUNCTION_STARTS]: Use it.
2635
2636 2011-08-08 Eli Zaretskii <eliz@gnu.org>
2637
2638 * xdisp.c (forward_to_next_line_start): Allow to use the
2639 no-display-properties-and-no-overlays under bidi display.
2640 Set disp_pos in the bidi iterator to avoid searches for display
2641 properties and overlays.
2642
2643 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
2644
2645 * editfns.c (Fset_time_zone_rule): Document relationship with the
2646 setenv function.
2647
2648 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
2649 the font entity extracted from the cache (Bug#8109).
2650
2651 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
2652
2653 * composite.c (autocmp_chars): Don't reset point. That is done by
2654 restore_point_unwind (Bug#5984).
2655
2656 2011-08-07 Juri Linkov <juri@jurta.org>
2657
2658 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
2659 to show the arg `TIME' instead of `TIMEVAL'.
2660
2661 2011-08-06 Eli Zaretskii <eliz@gnu.org>
2662
2663 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
2664 display property strides EOL and includes a newline, as in
2665 longlines-mode. (Bug#9254)
2666 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
2667 word-wrap under bidirectional display. (Bug#9224)
2668
2669 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
2670 is non-zero, even if the data buffer is NULL. Fixes a crash in
2671 vertical-motion with longlines-mode. (Bug#9254)
2672
2673 2011-08-05 Eli Zaretskii <eliz@gnu.org>
2674
2675 * bidi.c <bidi_cache_total_alloc>: Now static.
2676 (bidi_initialize): Initialize bidi_cache_total_alloc.
2677
2678 * xdisp.c (display_line): Release buffer allocated for shelved bidi
2679 cache. (Bug#9221)
2680
2681 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
2682 amount allocated this far in `bidi_cache_total_alloc'.
2683 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
2684 non-zero, only free the data buffer without restoring the cache
2685 contents. All callers changed.
2686
2687 * dispextern.h (bidi_unshelve_cache): Update prototype.
2688
2689 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
2690 (move_it_in_display_line, move_it_to)
2691 (move_it_vertically_backward, move_it_by_lines): Replace the call
2692 to xfree to an equivalent call to bidi_unshelve_cache.
2693 (move_it_in_display_line_to): Fix logic of returning
2694 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
2695
2696 2011-08-05 Eli Zaretskii <eliz@gnu.org>
2697
2698 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
2699 came from a string character with a `cursor' property. (Bug#9229)
2700
2701 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
2702
2703 * Makefile.in (LIB_PTHREAD): New variable.
2704 (LIBES): Add LIB_PTHREAD (Bug#9216).
2705
2706 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
2707 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
2708
2709 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
2710
2711 * regex.c (re_iswctype): Remove some redundant boolean conversions.
2712
2713 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
2714
2715 * xterm.c (x_find_topmost_parent): New function.
2716 (x_set_frame_alpha): Find topmost parent window with
2717 x_find_topmost_parent and set the property there also (bug#9181).
2718 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
2719
2720 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
2721
2722 * callproc.c (Fcall_process): Avoid vfork clobbering
2723 the local vars buffer, coding_systems, current_dir.
2724
2725 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
2726
2727 * keymap.c (Fmake_composed_keymap): Move to subr.el.
2728
2729 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
2730
2731 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
2732 so that it is not optimized away.
2733
2734 * xdisp.c (compute_display_string_pos): Remove unused local.
2735
2736 2011-08-02 Eli Zaretskii <eliz@gnu.org>
2737
2738 Fix slow cursor motion and scrolling in large buffers with
2739 selective display, like Org Mode buffers. (Bug#9218)
2740
2741 * dispextern.h (struct bidi_it): New member disp_prop_p.
2742
2743 * xdisp.c: Remove one-slot cache of display string positions.
2744 (compute_display_string_pos): Accept an additional argument
2745 DISP_PROP_P; callers changed. Scan at most 5K characters forward
2746 for a display string or property. If found, set DISP_PROP_P
2747 non-zero.
2748
2749 * bidi.c (bidi_fetch_char): Accept an additional argument
2750 DISP_PROP_P, and pass it to compute_display_string_pos.
2751 Only handle text covered by a display string if DISP_PROP_P is returned
2752 non-zero. All callers of bidi_fetch_char changed.
2753
2754 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
2755
2756 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
2757
2758 2010-12-03 Don March <don@ohspite.net>
2759
2760 * keymap.c (Fdefine_key): Fix non-prefix key error message when
2761 last character M-[char] is translated to ESC [char] (bug#7541).
2762
2763 2011-08-02 Kenichi Handa <handa@m17n.org>
2764
2765 * lisp.h (uniprop_table): Extern it.
2766
2767 * chartab.c (uniprop_table): Make it non-static.
2768
2769 2011-08-01 Eli Zaretskii <eliz@gnu.org>
2770
2771 * xdisp.c (forward_to_next_line_start): Accept additional argument
2772 BIDI_IT_PREV, and store into it the state of the bidi iterator had
2773 on the newline.
2774 (reseat_at_next_visible_line_start): Use the bidi iterator state
2775 returned by forward_to_next_line_start to restore the state of
2776 it->bidi_it after backing up to previous newline. (Bug#9212)
2777
2778 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
2779
2780 * regex.c (re_comp): Protoize.
2781 (re_exec): Fix return type.
2782 (regexec): Fix type of `ret'. (Bug#9203)
2783
2784 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
2785
2786 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
2787 This is needed if max-image-size is a floating-point number.
2788
2789 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
2790
2791 * print.c (print_object): Print empty symbol as ##.
2792
2793 * lread.c (read1): Read ## as empty symbol.
2794
2795 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
2796
2797 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
2798 setting frame foreground color (Bug#9175).
2799 (x_set_background_color): Likewise.
2800
2801 * nsmenu.m (-setText): Size tooltip dimensions precisely to
2802 contents (Bug#9176).
2803 (EmacsTooltip -init): Remove bezels and add shadows to
2804 tooltip windows.
2805
2806 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
2807 or scroll bar (Bug#8470).
2808
2809 * nsfont.m (nsfont_open): Remove assignment to voffset and
2810 unnecessary vars hshink, expand, hd, full_height, min_height.
2811 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
2812
2813 * nsterm.h (nsfont_info): Remove voffset field.
2814
2815 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
2816
2817 Implement strike-through and overline on NextStep (Bug#8863).
2818
2819 * nsfont.m (nsfont_open): Use underline position provided by font,
2820 instead of hard-coded value of 2.
2821 (nsfont_draw): Call ns_draw_text_decoration instead.
2822
2823 * nsterm.h: Add declaration for ns_draw_text_decoration.
2824
2825 * nsterm.m (ns_draw_text_decoration): New function for drawing
2826 underline, overline, and strike-through.
2827 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
2828 ns_draw_text_decoration. Change treatment of cursor drawing to
2829 accommodate underlining, etc.
2830
2831 2011-07-28 Eli Zaretskii <eliz@gnu.org>
2832
2833 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
2834 default.
2835
2836 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
2837
2838 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
2839 Without this fix, if a signal arrives just after memory fills up,
2840 'malloc' might be invoked reentrantly.
2841
2842 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
2843 In other words, assume that every image size is allowed, on non-X
2844 hosts. This assumption is probably wrong, but it lets Emacs compile.
2845
2846 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
2847
2848 * regex.c (re_iswctype): Convert return values to boolean.
2849
2850 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
2851
2852 * xdisp.c (compute_display_string_pos): Don't use cached display
2853 string position if the buffer had its restriction changed.
2854 (Bug#9184)
2855
2856 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
2857
2858 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
2859
2860 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
2861
2862 Integer signedness and overflow and related fixes. (Bug#9079)
2863
2864 * bidi.c: Integer size and overflow fixes.
2865 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
2866 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
2867 (bidi_cache_find_level_change, bidi_cache_ensure_space)
2868 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
2869 (bidi_find_other_level_edge):
2870 Use ptrdiff_t instead of EMACS_INT where either will do.
2871 This works better on 32-bit hosts configured --with-wide-int.
2872 (bidi_cache_ensure_space): Check for size-calculation overflow.
2873 Use % rather than repeated addition, for better worst-case speed.
2874 Don't set bidi_cache_size until after xrealloc returns, because it
2875 might not return.
2876 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
2877 (bidi_cache_ensure_space): Also check that the bidi cache size
2878 does not exceed that of the largest Lisp string or buffer. See Eli
2879 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
2880
2881 * alloc.c (__malloc_size_t): Remove.
2882 All uses replaced by size_t. See Andreas Schwab's note
2883 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
2884
2885 * image.c: Improve checking for integer overflow.
2886 (check_image_size): Assume that f is nonnull, since
2887 it is always nonnull in practice. This is one less thing to
2888 worry about when checking for integer overflow later.
2889 (x_check_image_size): New function, which checks for integer
2890 overflow issues inside X.
2891 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
2892 This removes the need for a memory_full check.
2893 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
2894 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
2895 (xbm_read_bitmap_data): Change locals back to 'int', since
2896 their values must fit in 'int'.
2897 (xpm_load_image, png_load, tiff_load):
2898 Invoke x_create_x_image_and_pixmap earlier,
2899 to avoid much needless work if the image is too large.
2900 (tiff_load): Treat overly large images as if
2901 x_create_x_image_and_pixmap failed, not as malloc failures.
2902 (gs_load): Use x_check_image_size.
2903
2904 * gtkutil.c: Omit integer casts.
2905 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
2906 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
2907
2908 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
2909
2910 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
2911 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
2912 would wrongly return t on a 64-bit host.
2913
2914 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
2915 The plain *_OVERFLOW macros run afoul of GCC bug 49705
2916 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
2917 and therefore cause GCC to emit a bogus diagnostic in some cases.
2918
2919 * image.c: Integer signedness and overflow and related fixes.
2920 This is not an exhaustive set of fixes, but it's time to
2921 record what I've got.
2922 (lookup_pixel_color, check_image_size): Remove redundant decls.
2923 (check_image_size): Don't assume that arbitrary EMACS_INT values
2924 fit in 'int', or that arbitrary 'double' values fit in 'int'.
2925 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
2926 (tiff_load, imagemagick_load_image):
2927 Check for overflow in size calculations.
2928 (x_create_x_image_and_pixmap): Remove unnecessary test for
2929 xmalloc returning NULL; that can't happen.
2930 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
2931 (xpm_color_bucket): Use better integer hashing function.
2932 (xpm_cache_color): Don't possibly over-allocate memory.
2933 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
2934 (gif_memory_source):
2935 Use ptrdiff_t, not int or size_t, to record sizes.
2936 (png_load): Don't assume values greater than 2**31 fit in 'int'.
2937 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
2938 either works, as we prefer signed integers.
2939 (tiff_read_from_memory, tiff_write_from_memory):
2940 Return tsize_t, not size_t, since that's what the TIFF API wants.
2941 (tiff_read_from_memory): Don't fail simply because the read would
2942 go past EOF; instead, return a short read.
2943 (tiff_load): Omit no-longer-needed casts.
2944 (Fimagemagick_types): Don't assume size fits into 'int'.
2945
2946 Improve hashing quality when configured --with-wide-int.
2947 * fns.c (hash_string): New function, taken from sxhash_string.
2948 Do not discard information about ASCII character case; this
2949 discarding is no longer needed.
2950 (sxhash-string): Use it. Change sig to match it. Caller changed.
2951 * lisp.h: Declare it.
2952 * lread.c (hash_string): Remove, since we now use fns.c's version.
2953 The fns.c version returns a wider integer if --with-wide-int is
2954 specified, so this should help the quality of the hashing a bit.
2955
2956 * emacs.c: Integer overflow minor fix.
2957 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
2958 Define only if GNU_LINUX.
2959 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
2960
2961 * dispnew.c: Integer signedness and overflow fixes.
2962 Remove unnecessary forward decls, that were a maintenance hassle.
2963 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
2964 All uses changed.
2965 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
2966 (scrolling_window): Use ptrdiff_t, not int, for byte count.
2967 (prepare_desired_row, line_draw_cost):
2968 Use int, not unsigned, where either works.
2969 (save_current_matrix, restore_current_matrix):
2970 Use ptrdiff_t, not size_t, where either works.
2971 (init_display): Check for overflow more accurately, and without
2972 relying on undefined behavior.
2973
2974 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
2975 Remove, replacing with the new symbols in lisp.h. All uses changed.
2976 * fileio.c (make_temp_name):
2977 * filelock.c (lock_file_1, lock_file):
2978 * xdisp.c (message_dolog):
2979 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
2980 Use pMd etc. instead.
2981 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
2982 replacing the pWIDE etc. symbols removed from editfns.c.
2983
2984 * keyboard.h (num_input_events): Now uintmax_t.
2985 This is (very slightly) less likely to mess up due to wraparound.
2986 All uses changed.
2987
2988 * buffer.c: Integer signedness fixes.
2989 (alloc_buffer_text, enlarge_buffer_text):
2990 Use ptrdiff_t rather than size_t when either will do, as we prefer
2991 signed integers.
2992
2993 * alloc.c: Integer signedness and overflow fixes.
2994 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
2995 (__malloc_size_t): Default to size_t, not to int.
2996 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
2997 (Fgarbage_collect, mark_object_loop_halt, mark_object):
2998 Prefer ptrdiff_t to size_t when either would do, as we prefer
2999 signed integers.
3000 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
3001 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
3002 Now const. Initialize with values that are in range even if char
3003 is signed.
3004 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
3005 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
3006 These functions do the right thing with sizes > 2**32.
3007 (check_depth): Now ptrdiff_t, not int.
3008 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
3009 Adjust to new way of storing sizes. Check for size overflow bugs
3010 in rest of code.
3011 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
3012 slightly wrong anyway, as it missed one instance of
3013 XMALLOC_OVERRUN_CHECK_OVERHEAD.
3014 (refill_memory_reserve): Omit needless cast to size_t.
3015 (mark_object_loop_halt): Mark as externally visible.
3016
3017 * xselect.c: Integer signedness and overflow fixes.
3018 (Fx_register_dnd_atom, x_handle_dnd_message):
3019 Use ptrdiff_t, not size_t, since we prefer signed.
3020 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
3021 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
3022 x_dnd_atoms_size and x_dnd_atoms_length.
3023
3024 * doprnt.c: Prefer signed to unsigned when either works.
3025 * eval.c (verror):
3026 * doprnt.c (doprnt):
3027 * lisp.h (doprnt):
3028 * xdisp.c (vmessage):
3029 Use ptrdiff_t, not size_t, when using or implementing doprnt,
3030 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
3031 prefer signed arithmetic to avoid comparison confusion.
3032 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
3033 but is a bit tricky.
3034
3035 Assume freestanding C89 headers, string.h, stdlib.h.
3036 * data.c, doprnt.c, floatfns.c, print.c:
3037 Include float.h unconditionally.
3038 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
3039 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
3040 * regex.c: Likewise for stddef.h, string.h.
3041 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
3042 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
3043 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
3044 (STDC_HEADERS): Remove obsolete defines.
3045 * sysdep.c: Include limits.h unconditionally.
3046
3047 Assume support for memcmp, memcpy, memmove, memset.
3048 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
3049 * regex.c (memcmp, memcpy):
3050 Remove; we assume C89 now.
3051
3052 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
3053 (__malloc_safe_bcopy): Remove; no longer needed.
3054
3055 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
3056 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
3057 well either way, and we prefer signed to unsigned.
3058
3059 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
3060
3061 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
3062 closes the connection while we're reading (bug#9182).
3063
3064 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
3065
3066 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
3067 are specified (Bug#9168).
3068
3069 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
3070
3071 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
3072 Found by GCC static checking and --with-wide-int on a 32-bit host.
3073
3074 2011-07-25 Eli Zaretskii <eliz@gnu.org>
3075
3076 * xdisp.c (compute_display_string_pos): Fix logic of caching
3077 previous display string position. Initialize cached_prev_pos to
3078 -1. Fixes slow-down at the beginning of a buffer.
3079
3080 2011-07-24 Eli Zaretskii <eliz@gnu.org>
3081
3082 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
3083 for attrs[LFACE_FONTSET_INDEX].
3084
3085 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
3086
3087 * xml.c (parse_region): Remove unused local
3088 that was recently introduced.
3089
3090 2011-07-23 Eli Zaretskii <eliz@gnu.org>
3091
3092 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
3093 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
3094
3095 * xdisp.c (move_it_in_display_line_to): Record the best matching
3096 position for TO_CHARPOS while scanning the line, and restore it on
3097 exit if none of the characters scanned was an exact match.
3098 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
3099 when exact match is impossible due to invisible text, and the
3100 lines are truncated.
3101
3102 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
3103
3104 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
3105 for OSX >= 10.7.
3106
3107 2011-07-22 Eli Zaretskii <eliz@gnu.org>
3108
3109 Fix a significant slow-down of cursor motion with C-n, C-p,
3110 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
3111 auto-repeat under bidi redisplay in fontified buffers.
3112 * xdisp.c (compute_stop_pos_backwards): New function.
3113 (next_element_from_buffer): Call compute_stop_pos_backwards to
3114 find a suitable prev_stop when we find ourselves before
3115 base_level_stop.
3116 (reseat): Don't look for prev_stop, as that could mean a very long
3117 run.
3118 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
3119 <cached_disp_overlay_modiff>: Cache for last found display string
3120 position.
3121 (compute_display_string_pos): Return the cached position if asked
3122 about the same buffer in the same area of character positions, and
3123 the buffer wasn't changed since the time the display string
3124 position was cached.
3125
3126 2011-07-22 Eli Zaretskii <eliz@gnu.org>
3127
3128 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
3129 is an integer, which is important for empty lines. (Bug#9149)
3130
3131 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
3132
3133 * frame.c (Fmodify_frame_parameters): In tty case, update the
3134 default face if necessary (Bug#4238).
3135
3136 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
3137
3138 * editfns.c (Fstring_to_char): No need to explain what a character
3139 is in the docstring (Bug#6576).
3140
3141 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
3142
3143 * xml.c (parse_region): Make sure we always return a tree.
3144
3145 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
3146
3147 * xml.c (parse_region): If a document contains only comments,
3148 return that, too.
3149
3150 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
3151
3152 * xml.c (make_dom): Return comments, too.
3153
3154 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
3155
3156 Port to OpenBSD.
3157 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
3158 and the surrounding thread.
3159 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
3160 rather than fgets, and retry after EINTR. Otherwise, 'emacs
3161 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
3162 timer goes off.
3163 * s/openbsd.h (BROKEN_SIGIO): Define.
3164 * unexelf.c (unexec) [__OpenBSD__]:
3165 Don't update the .mdebug section of the Alpha COFF symbol table.
3166
3167 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
3168
3169 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
3170 (bug#8460).
3171
3172 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
3173
3174 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
3175 This fixes some race conditions on the permissions of any newly
3176 created file.
3177
3178 * alloc.c (valid_pointer_p): Use pipe, not open.
3179 This fixes some permissions issues when debugging.
3180
3181 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
3182 If fchown fails to set both uid and gid, try to set just gid,
3183 as that is sometimes allowed. Adjust the file's mode to eliminate
3184 setuid or setgid bits that are inappropriate if fchown fails.
3185
3186 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
3187
3188 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
3189 to compare Lisp_Objects.
3190 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
3191 global_gnutls_log_level, don't mistake it for a Lisp_Object.
3192 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
3193
3194 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
3195
3196 * lread.c (read_integer): Unread even EOF character.
3197 (read1): Likewise. Properly record start position of symbol.
3198
3199 * lread.c (read1): Read `#:' as empty uninterned symbol if no
3200 symbol character follows.
3201
3202 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
3203
3204 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
3205 This works around a problem with the previous change to Fcopy_file.
3206 Recent glibc declares fchown with __attribute__((warn_unused_result)),
3207 and without this change, GCC might complain about discarding
3208 fchown's return value.
3209
3210 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
3211
3212 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
3213
3214 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
3215
3216 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
3217
3218 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
3219
3220 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
3221 it's used from the C level.
3222
3223 * process.c: Use the same condition for POLL_FOR_INPUT in both
3224 keyboard.c and process.c (bug#1858).
3225
3226 2011-07-09 Lawrence Mitchell <wence@gmx.li>
3227
3228 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
3229 (Fgnutls_boot): Use it.
3230
3231 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
3232
3233 * doc.c (Fsubstitute_command_keys): Revert last change.
3234
3235 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
3236
3237 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
3238 quotes the next character, and doesn't affect other longer
3239 sequences (bug#8935).
3240
3241 * lread.c (syms_of_lread): Clarify that is isn't only
3242 `eval-buffer' and `eval-defun' that's affected by
3243 `lexical-binding' (bug#8460).
3244
3245 2011-07-15 Eli Zaretskii <eliz@gnu.org>
3246
3247 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
3248 bidi redisplay when a line includes both an image and is truncated.
3249
3250 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
3251
3252 Fix minor problems found by static checking.
3253 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
3254 (elsz): Now a signed constant, not a size_t var. We prefer signed
3255 types to unsigned, to avoid integer comparison confusion. Without
3256 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
3257 "cannot optimize loop, the loop counter may overflow", a symptom
3258 of the confusion.
3259 * indent.c (Fvertical_motion): Mark locals as initialized.
3260 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
3261
3262 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
3263
3264 * search.c (Fre_search_backward): Mention `case-fold-search' in
3265 all the re_search_* functions (bug#8138).
3266
3267 * keyboard.c (Fopen_dribble_file): Document when the file is
3268 closed (bug#8056).
3269
3270 2011-07-14 Eli Zaretskii <eliz@gnu.org>
3271
3272 * bidi.c (bidi_dump_cached_states): Fix format of displaying
3273 bidi_cache_idx.
3274
3275 Support bidi reordering of display and overlay strings.
3276 * xdisp.c (compute_display_string_pos)
3277 (compute_display_string_end): Accept additional argument STRING.
3278 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
3279 (reseat_to_string): Initialize bidi_it->string.s and
3280 bidi_it->string.schars.
3281 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
3282 NULL (avoids a crash in bidi_paragraph_init).
3283 Initialize itb.string.lstring.
3284 (init_iterator): Call bidi_init_it only of a valid
3285 buffer position was specified. Initialize paragraph_embedding to
3286 L2R.
3287 (reseat_to_string): Initialize the bidi iterator.
3288 (display_string): If we need to ignore text properties of
3289 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
3290 original value of -1 will not work with bidi.)
3291 (compute_display_string_pos): First arg is now struct
3292 `text_pos *'; all callers changed. Support display properties on
3293 Lisp strings.
3294 (compute_display_string_end): Support display properties on Lisp
3295 strings.
3296 (init_iterator, reseat_1, reseat_to_string): Initialize the
3297 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
3298 when iterating on a string not from display properties).
3299 (compute_display_string_pos, compute_display_string_end):
3300 Fix calculation of the object to scan. Fixes an error when using
3301 arrow keys.
3302 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
3303 base_level_stop; instead, set base_level_stop to BEGV.
3304 Fixes crashes in vertical-motion.
3305 (next_element_from_buffer): Improve commentary for when
3306 the iterator is before prev_stop.
3307 (init_iterator): Initialize bidi_p from the default value of
3308 bidi-display-reordering, not from buffer-local value. Use the
3309 buffer-local value only if initializing for buffer iteration.
3310 (handle_invisible_prop): Support invisible properties on strings
3311 that are being bidi-reordered.
3312 (set_iterator_to_next): Support bidi reordering of C strings and
3313 Lisp strings.
3314 (next_element_from_string): Support bidi reordering of Lisp
3315 strings.
3316 (handle_stop_backwards): Support Lisp strings as well.
3317 (display_string): Support display of R2L glyph rows.
3318 Use IT_STRING_CHARPOS when displaying from a Lisp string.
3319 (init_iterator): Don't initialize it->bidi_p for strings
3320 here.
3321 (reseat_to_string): Initialize it->bidi_p for strings here.
3322 (next_element_from_string, next_element_from_c_string)
3323 (next_element_from_buffer): Add xassert's for correspondence
3324 between IT's object being iterated and it->bidi_it.string
3325 structure.
3326 (face_before_or_after_it_pos): Support bidi iteration.
3327 (next_element_from_c_string): Handle the case of the first string
3328 character that is not the first one in the visual order.
3329 (get_visually_first_element): New function, refactored from common
3330 parts of next_element_from_buffer, next_element_from_string, and
3331 next_element_from_c_string.
3332 (tool_bar_lines_needed, redisplay_tool_bar)
3333 (display_menu_bar): Force left-to-right direction. Add a FIXME
3334 comment for making that be controlled by a user option.
3335 (push_it, pop_it): Save and restore the state of the
3336 bidi iterator. Save and restore the bidi_p flag.
3337 (pop_it): Iterate out of display property for string iteration as
3338 well.
3339 (iterate_out_of_display_property): Support iteration over strings.
3340 (handle_single_display_spec): Set up it->bidi_it for iteration
3341 over a display string, and call bidi_init_it.
3342 (handle_single_display_spec, next_overlay_string)
3343 (get_overlay_strings_1, push_display_prop): Set up the bidi
3344 iterator for displaying display or overlay strings.
3345 (forward_to_next_line_start): Don't use the shortcut if
3346 bidi-iterating.
3347 (back_to_previous_visible_line_start): If handle_display_prop
3348 pushed the iterator stack, restore the internal state of the bidi
3349 iterator by calling bidi_pop_it same number of times.
3350 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
3351 and we are bidi-iterating, don't decrement the iterator position;
3352 instead, set the first_elt flag in the bidi iterator, to produce
3353 the same effect.
3354 (reseat_1): Remove redundant setting of string_from_display_prop_p.
3355 (push_display_prop): xassert that we are iterating a buffer.
3356 (push_it, pop_it): Save and restore paragraph_embedding member.
3357 (handle_single_display_spec, next_overlay_string)
3358 (get_overlay_strings_1, reseat_1, reseat_to_string)
3359 (push_display_prop): Set up the `unibyte' member of bidi_it.string
3360 correctly. Don't assume unibyte strings are not bidi-reordered.
3361 (compute_display_string_pos)
3362 (compute_display_string_end): Fix handling the case of C string.
3363 (push_it, pop_it): Save and restore from_disp_prop_p.
3364 (handle_single_display_spec, push_display_prop): Set the
3365 from_disp_prop_p flag.
3366 (get_overlay_strings_1): Reset the from_disp_prop_p flag.
3367 (pop_it): Call iterate_out_of_display_property only if we are
3368 popping after iteration over a string that came from a display
3369 property. Fix a typo in popping stretch info. Add an assertion
3370 for verifying that the iterator position is in sync with the bidi
3371 iterator.
3372 (handle_single_display_spec, get_overlay_strings_1)
3373 (push_display_prop): Fix initialization of paragraph direction for
3374 string when that of the parent object is not yet determined.
3375 (reseat_1): Call bidi_init_it to resync the bidi
3376 iterator with IT's position. (Bug#7616)
3377 (find_row_edges): If ROW->start.pos gives position
3378 smaller than min_pos, use it as ROW->minpos. (Bug#7616)
3379 (handle_stop, back_to_previous_visible_line_start, reseat_1):
3380 Reset the from_disp_prop_p flag.
3381 (SAVE_IT, RESTORE_IT): New macros.
3382 (pos_visible_p, face_before_or_after_it_pos)

3824
3825 Random fixes. E.g., (random) never returned negative values.
3826 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
3827 subseconds part to the entropy, as that's a bit more random.
3828 Prefer signed to unsigned, since the signedness doesn't matter and
3829 in general we prefer signed. When given a limit, use a
3830 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
3831 latter isn't right if USE_2_TAGS_FOR_INTS.
3832 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
3833 not 0..VALMASK. Don't discard "excess" bits that random () returns.

3846 This is more efficient than Ffile_directory_p and avoids a minor race.
3847
3848 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
3849
3850 * buffer.c (Foverlay_put): Say what the return value is

3872 Qgnutls_bootprop_verify_hostname_error, an error for
3873 Qgnutls_bootprop_verify_error (which is no longer used).
3874
3875 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
3876 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.
3877 Also (re)move comments that are misplaced or no longer relevant.

3978 * eval.c (struct backtrace): Simplify and port the data structure.
3979 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
3980 signed bit field, as this assumption is not portable and it makes
3981 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
3982 "char debug_on_exit : 1" as this is not portable either; instead,
3983 use the portable "unsigned int debug_on_exit : 1". Remove unused
3984 member evalargs. Remove obsolete comments about cc bombing out.

4214 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
4215 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
4216 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
4217 Now static.
4218 (debug_method_add): Use va_list and vsprintf rather than relying
4219 on undefined behavior with wrong number of arguments.
4220 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
4221 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
4222 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
4223 since we're not interested in debugging glyphs with old libraries.
4224 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
4225 GCC 4.6.0's static checking.
4226
4227 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
4228
4229 Integer overflow and signedness fixes (Bug#8873).
4230 A few related buffer overrun fixes, too.

4242 (.bitmaps_last):
4243 * xfaces.c (load_pixmap):
4244 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
4245 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
4246 (.bitmaps_last, struct x_output.icon_bitmap):
4247 Use ptrdiff_t, not int, for bitmap indexes.
4248 (x_allocate_bitmap_record): Check for size overflow.
4249 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
4250
4251 Use ptrdiff_t, not int, for overlay counts.
4252 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
4253 * editfns.c (overlays_around, get_pos_property):
4254 * textprop.c (get_char_property_and_overlay):
4255 * xdisp.c (next_overlay_change, note_mouse_highlight):
4256 * xfaces.c (face_at_buffer_position):
4257 * buffer.c (OVERLAY_COUNT_MAX): New macro.
4258 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
4259 (Fnext_overlay_change, Fprevious_overlay_change)
4260 (mouse_face_overlay_overlaps, Foverlays_in):
4261 Use ptrdiff_t, not int, for sizes.
4262 (overlays_at, overlays_in): Check for size-calculation overflow.
4263
4264 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
4265
4266 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
4267 (x_session_initialize): Do not assume string length fits in int.
4268
4269 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
4270 This is unlikely, but can occur if DPI is outlandish.
4271
4272 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
4273 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
4274
4275 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
4276 * xrdb.c (magic_file_p, search_magic_path):
4277 Omit last arg SUFFIX; it was always 0. All callers changed.
4278 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
4279
4280 * xfont.c (xfont_match): Avoid need for strlen.
4281
4282 * xfns.c: Don't assume strlen fits in int.
4283 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
4284
4285 * xdisp.c (message_log_check_duplicate): Return intmax_t,
4286 not unsigned long, as we prefer signed integers. All callers changed.
4287 Detect integer overflow in repeat count.
4288 (message_dolog): Don't assume print length fits in 39 bytes.
4289 (display_mode_element): Don't assume strlen fits in int.
4290
4291 * termcap.c: Don't assume sizes fit in int and never overflow.
4292 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
4293 (gobble_line): Check for size-calculation overflow.
4294
4295 * minibuf.c (Fread_buffer):
4296 * lread.c (intern, intern_c_string):
4297 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
4298 Don't assume string length fits in int.
4299
4300 * keyboard.c (parse_tool_bar_item):
4301 * gtkutil.c (style_changed_cb): Avoid need for strlen.
4302
4303 * font.c: Don't assume string length fits in int.
4304 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
4305 Use ptrdiff_t, not int.
4306 (font_intern_prop): Don't assume string length fits in int.
4307 Don't assume integer property fits in fixnum.
4308 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
4309
4310 * filelock.c: Fix some buffer overrun and integer overflow issues.
4311 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
4312 Reformulate so as not to need the command string.
4313 Invoke gzip -cd rather than gunzip, as it's more portable.
4314 (lock_info_type, lock_file_1, lock_file):
4315 Don't assume pid_t and time_t fit in unsigned long.
4316 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
4317 (current_lock_owner): Prefer signed type for sizes.
4318 Use memcpy, not strncpy, where memcpy is what is really wanted.
4319 Don't assume (via atoi) that time_t and pid_t fit in int.
4320 Check for time_t and/or pid_t out of range, e.g., via a network share.
4321 Don't alloca where an auto var works fine.
4322
4323 * fileio.c: Fix some integer overflow issues.
4324 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
4325 Don't assume string length fits in int.
4326 (directory_file_name): Don't assume string length fits in long.
4327 (make_temp_name): Don't assume pid fits in int, or that its print
4328 length is less than 20.
4329
4330 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
4331
4332 * coding.c (make_subsidiaries): Don't assume string length fits in int.
4333
4334 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
4335
4336 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
4337 We prefer signed integers, even for size calculations.
4338
4339 * emacs.c: Don't assume string length fits in 'int'.
4340 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
4341 (main): Don't invoke strlen when not needed.
4342
4343 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
4344 (XD_DEBUG_MESSAGE): Don't waste a byte.
4345
4346 * callproc.c (getenv_internal_1, getenv_internal)
4347 (Fgetenv_internal):
4348 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
4349
4350 * lread.c (invalid_syntax): Omit length argument.
4351 All uses changed. This doesn't fix a bug, but it simplifies the
4352 code away from its former Hollerith-constant appearance, and it's
4353 one less 'int' to worry about when looking at integer-overflow issues.
4354 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
4355
4356 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
4357 This didn't break anything, but it didn't help either.
4358 It's confusing to put a bogus integer in a place where the actual
4359 value does not matter.
4360 (LIST_END_P): Remove unused macro and its bogus comment.
4361 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
4362
4363 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
4364 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
4365 implementation.
4366 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
4367 We prefer signed types, and the value cannot exceed the EMACS_INT
4368 range anyway (because otherwise the length would not be representable).
4369 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
4370 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
4371 This avoids a GCC warning when WIDE_EMACS_INT.
4372
4373 * indent.c (sane_tab_width): New function.
4374 (current_column, scan_for_column, Findent_to, position_indentation)
4375 (compute_motion): Use it. This is just for clarity.
4376 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
4377
4378 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
4379
4380 * lisp.h (lint_assume): New macro.
4381 * composite.c (composition_gstring_put_cache):
4382 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
4383
4384 * editfns.c, insdel.c:
4385 Omit unnecessary forward decls, to simplify future changes.
4386
4387 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
4388
4389 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
4390
4391 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
4392 Use much-faster test for byte-length change.
4393 Don't assume string byte-length fits in 'int'.
4394 Check that character arg fits in 'int'.
4395 (mapcar1): Declare byte as byte, for clarity.
4396
4397 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
4398
4399 * fns.c (concat): Catch string overflow earlier.
4400 Do not rely on integer wraparound.
4401
4402 * dispextern.h (struct it.overlay_strings_charpos)
4403 (struct it.selective): Now EMACS_INT, not int.
4404 * xdisp.c (forward_to_next_line_start)
4405 (back_to_previous_visible_line_start)
4406 (reseat_at_next_visible_line_start, next_element_from_buffer):
4407 Don't arbitrarily truncate the value of 'selective' to int.
4408
4409 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
4410
4411 * composite.c: Don't truncate sizes to 'int'.
4412 (composition_gstring_p, composition_reseat_it)
4413 (composition_adjust_point): Use EMACS_INT, not int.
4414 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
4415 not EMACS_UINT, for indexes.
4416
4417 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
4418
4419 * buffer.c: Include <verify.h>.
4420 (struct sortvec.priority, struct sortstr.priority):
4421 Now EMACS_INT, not int.
4422 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
4423 (struct sortstr.size, record_overlay_string)
4424 (struct sortstrlist.size, struct sortlist.used):
4425 Don't truncate size to int.
4426 (record_overlay_string): Check for size-calculation overflow.
4427 (init_buffer_once): Check at compile-time, not run-time.
4428
4429 2011-06-22 Jim Meyering <meyering@redhat.com>
4430
4431 Don't leak an XBM-image-sized buffer
4432 * image.c (xbm_load): Free the image buffer after using it.
4433
4434 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
4435
4436 Port to Sun C.
4437 * composite.c (find_automatic_composition): Omit needless 'return 0;'
4438 that Sun C diagnosed.
4439 * fns.c (secure_hash): Fix pointer signedness issue.
4440 * intervals.c (static_offset_intervals): New function.
4441 (offset_intervals): Use it.
4442
4443 2011-06-21 Leo Liu <sdl.web@gmail.com>
4444
4445 * deps.mk (fns.o):
4446 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
4447 sha512.h.
4448
4449 * fns.c (secure_hash): Rename from crypto_hash_function and change
4450 the first arg to accept symbols.
4451 (Fsecure_hash): New primitive.
4452 (syms_of_fns): New symbols.
4453
4454 2011-06-20 Deniz Dogan <deniz@dogan.se>
4455
4456 * process.c (Fset_process_buffer): Clarify return value in
4457 docstring.
4458
4459 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
4460
4461 * dispnew.c (add_window_display_history): Use BVAR.
4462
4463 * xdisp.c (debug_method_add): Use BVAR.
4464 (check_window_end, dump_glyph_matrix, dump_glyph)
4465 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
4466
4467 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
4468 Likewise.
4469
4470 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
4471 check till after the cache is created in init_frame_faces.
4472
4473 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
4474
4475 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
4476
4477 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
4478
4479 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
4480 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
4481 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
4482
4483 Improve buffer-overflow checking (Bug#8873).
4484 * fileio.c (Finsert_file_contents):
4485 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
4486 Remove the old (too-loose) buffer overflow checks.
4487 They weren't needed, since make_gap checks for buffer overflow.
4488 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
4489 The old code merely checked for Emacs fixnum overflow, and relied
4490 on undefined (wraparound) behavior. The new code avoids undefined
4491 behavior, and also checks for ptrdiff_t and/or size_t overflow.
4492
4493 * editfns.c (Finsert_char): Don't dump core with very negative counts.
4494 Tune. Don't use wider integers than needed. Don't use alloca.
4495 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
4496
4497 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
4498
4499 * insdel.c, lisp.h (buffer_overflow): New function.
4500 (insert_from_buffer_1, replace_range, replace_range_2):
4501 * insdel.c (make_gap_larger):
4502 * editfns.c (Finsert_char):
4503 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
4504
4505 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
4506
4507 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
4508
4509 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
4510
4511 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
4512 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
4513
4514 * fileio.c: Don't assume EMACS_INT fits in off_t.
4515 (emacs_lseek): New static function.
4516 (Finsert_file_contents, Fwrite_region): Use it.
4517 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
4518
4519 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
4520
4521 * fns.c: Don't overflow int when computing a list length.
4522 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
4523 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
4524 truncation on 64-bit hosts. Check for QUIT every
4525 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
4526 faster and is responsive enough.
4527 (Flength): Report an error instead of overflowing an integer.
4528 (Fsafe_length): Return a float if the value is not representable
4529 as a fixnum. This shouldn't happen except in contrived situations.
4530 (Fnthcdr, Fsort): Don't assume list length fits in int.
4531 (Fcopy_sequence): Don't assume vector length fits in int.
4532
4533 * alloc.c: Check that resized vectors' lengths fit in fixnums.
4534 (header_size, word_size): New constants.
4535 (allocate_vectorlike): Don't check size overflow here.
4536 (allocate_vector): Check it here instead, since this is the only
4537 caller of allocate_vectorlike that could cause overflow.
4538 Check that the new vector's length is representable as a fixnum.
4539
4540 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
4541 The previous code was bogus. For example, next_almost_prime (32)
4542 returned 39, which is undesirable as it is a multiple of 3; and
4543 next_almost_prime (24) returned 25, which is a multiple of 5 so
4544 why was the code bothering to check for multiples of 7?
4545
4546 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
4547
4548 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
4549
4550 Variadic C functions now count arguments with ptrdiff_t.
4551 This partly undoes my 2011-03-30 change, which replaced int with size_t.
4552 Back then I didn't know that the Emacs coding style prefers signed int.
4553 Also, in the meantime I found a few more instances where arguments
4554 were being counted with int, which may truncate counts on 64-bit
4555 machines, or EMACS_INT, which may be unnecessarily wide.
4556 * lisp.h (struct Lisp_Subr.function.aMANY)
4557 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
4558 Arg counts are now ptrdiff_t, not size_t.
4559 All variadic functions and their callers changed accordingly.
4560 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
4561 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
4562 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
4563 * callint.c (Fcall_interactively): Check arg count for overflow,
4564 to avoid potential buffer overrun. Use signed char, not 'int',
4565 for 'varies' array, so that we needn't bother to check its size
4566 calculation for overflow.
4567 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
4568 * eval.c (apply_lambda):
4569 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
4570 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
4571 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
4572
4573 * callint.c (Fcall_interactively): Don't use index var as event count.
4574
4575 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
4576 * mem-limits.h (SIZE): Remove; no longer used.
4577
4578 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
4579
4580 Remove unnecessary casts.
4581 * xterm.c (x_term_init):
4582 * xfns.c (x_set_border_pixel):
4583 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
4584 These aren't needed now that we assume ANSI C.
4585
4586 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
4587 It's more likely to cause problems (due to unsigned overflow)
4588 than to cure them.
4589
4590 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
4591
4592 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
4593
4594 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
4595
4596 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
4597
4598 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
4599
4600 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
4601
4602 GLYPH_CODE_FACE returns EMACS_INT, not int.
4603 * dispextern.h (merge_faces):
4604 * xfaces.c (merge_faces):
4605 * xdisp.c (get_next_display_element, next_element_from_display_vector):
4606 Don't assume EMACS_INT fits in int.
4607
4608 * character.h (CHAR_VALID_P): Remove unused parameter.
4609 * fontset.c, lisp.h, xdisp.c: All uses changed.
4610
4611 * editfns.c (Ftranslate_region_internal): Omit redundant test.
4612
4613 * fns.c (concat): Minor tuning based on overflow analysis.
4614 This doesn't fix any bugs. Use int to hold character, instead
4615 of constantly refetching from Emacs object. Use XFASTINT, not
4616 XINT, for value known to be a character. Don't bother comparing
4617 a single byte to 0400, as it's always less.
4618
4619 * floatfns.c (Fexpt):
4620 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
4621
4622 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
4623 for characters.
4624
4625 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
4626
4627 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
4628 Without this fix, on a 64-bit host (aset S 0 4294967386) would
4629 incorrectly succeed when S was a string, because 4294967386 was
4630 truncated before it was used.
4631
4632 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
4633 Otherwise, an out-of-range integer could cause undefined behavior
4634 on a 64-bit host.
4635
4636 * composite.c: Use int, not EMACS_INT, for characters.
4637 (fill_gstring_body, composition_compute_stop_pos): Use int, not
4638 EMACS_INT, for values that are known to be in character range.
4639 This doesn't fix any bugs but is the usual style inside Emacs and
4640 may generate better code on 32-bit machines.
4641
4642 Make sure a 64-bit char is never passed to ENCODE_CHAR.
4643 This is for reasons similar to the recent CHAR_STRING fix.
4644 * charset.c (Fencode_char): Check that character arg is actually
4645 a character. Pass an int to ENCODE_CHAR.
4646 * charset.h (ENCODE_CHAR): Verify that the character argument is no
4647 wider than 'int', as a compile-time check to prevent future regressions
4648 in this area.
4649
4650 * character.c (char_string): Remove unnecessary casts.
4651
4652 Make sure a 64-bit char is never passed to CHAR_STRING.
4653 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
4654 by silently ignoring the top 32 bits, allowing some values
4655 that were far too large to be valid characters.
4656 * character.h: Include <verify.h>.
4657 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
4658 arguments are no wider than unsigned, as a compile-time check
4659 to prevent future regressions in this area.
4660 * data.c (Faset):
4661 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
4662 (Fsubst_char_in_region):
4663 * fns.c (concat):
4664 * xdisp.c (decode_mode_spec_coding):
4665 Adjust to CHAR_STRING's new requirement.
4666 * editfns.c (Finsert_char, Fsubst_char_in_region):
4667 * fns.c (concat): Check that character args are actually
4668 characters. Without this test, these functions did the wrong
4669 thing with wildly out-of-range values on 64-bit hosts.
4670
4671 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
4672 These casts should not be needed on 32-bit hosts, either.
4673 * keyboard.c (read_char):
4674 * lread.c (Fload): Remove casts to unsigned.
4675
4676 * lisp.h (UNSIGNED_CMP): New macro.
4677 This fixes comparison bugs on 64-bit hosts.
4678 (ASCII_CHAR_P): Use it.
4679 * casefiddle.c (casify_object):
4680 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
4681 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
4682 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
4683 * dispextern.h (FACE_FROM_ID):
4684 * keyboard.c (read_char): Use UNSIGNED_CMP.
4685
4686 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
4687 not to EMACS_INT, to avoid GCC warning.
4688
4689 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
4690
4691 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
4692 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
4693 isn't needed on 32-bit machines.
4694
4695 * buffer.c (Fgenerate_new_buffer_name):
4696 Use EMACS_INT for count, not int.
4697 (advance_to_char_boundary): Return EMACS_INT, not int.
4698
4699 * data.c (Qcompiled_function): Now static.
4700
4701 * window.c (window_body_lines): Now static.
4702
4703 * image.c (gif_load): Rename local to avoid shadowing.
4704
4705 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
4706 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
4707 * alloc.c (make_save_value): Integer argument is now of type
4708 ptrdiff_t, not int.
4709 (mark_object): Use ptrdiff_t, not int.
4710 * lisp.h (pD): New macro.
4711 * print.c (print_object): Use it.
4712
4713 * alloc.c: Use EMACS_INT, not int, to count objects.
4714 (total_conses, total_markers, total_symbols, total_vector_size)
4715 (total_free_conses, total_free_markers, total_free_symbols)
4716 (total_free_floats, total_floats, total_free_intervals)
4717 (total_intervals, total_strings, total_free_strings):
4718 Now EMACS_INT, not int. All uses changed.
4719 (Fgarbage_collect): Compute overall total using a double, so that
4720 integer overflow is less likely to be a problem. Check for overflow
4721 when converting back to an integer.
4722 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
4723 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
4724 These were 'int' variables that could overflow on 64-bit hosts;
4725 they were never used, so remove them instead of repairing them.
4726 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
4727 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
4728 Previously, this ceilinged at INT_MAX, but that doesn't work on
4729 64-bit machines.
4730 (allocate_pseudovector): Don't use EMACS_INT when int would do.
4731
4732 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
4733 (allocate_vectorlike): Check for ptrdiff_t overflow.
4734 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
4735 when a (possibly-narrower) signed value would do just as well.
4736 We prefer using signed arithmetic, to avoid comparison confusion.
4737
4738 * alloc.c: Catch some string size overflows that we were missing.
4739 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
4740 for convenience in STRING_BYTES_MAX.
4741 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
4742 The definition here is exact; the one in lisp.h was approximate.
4743 (allocate_string_data): Check for string overflow. This catches
4744 some instances we weren't catching before. Also, it catches
4745 size_t overflow on (unusual) hosts where SIZE_MAX <= min
4746 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
4747 and ptrdiff_t and EMACS_INT are both 64 bits.
4748
4749 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
4750 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
4751 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
4752
4753 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
4754
4755 * alloc.c (Fmake_string): Check for out-of-range init.
4756

4758
4759 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
4760
4761 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
4762
4763 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
4764 xg_get_default_scrollbar_width.
4765

4784
4785 2011-06-12 Martin Rudalics <rudalics@gmx.at>
4786
4787 * frame.c (make_frame): Call other_buffer_safely instead of
4788 other_buffer.
4789
4790 * window.c (temp_output_buffer_show): Call display_buffer with
4791 second argument Vtemp_buffer_show_specifiers and reset latter
4792 immediately after the call.

5258 (LARGE_REQUEST): New macro, so that the issue of large requests
5259 is separated from the issue of spare memory.
5260
5261 2011-06-05 Andreas Schwab <schwab@linux-m68k.org>
5262

5319 display string.
5320 (bidi_paragraph_init, bidi_resolve_explicit_1)
5321 (bidi_level_of_next_char): Call bidi_fetch_char and

5328 instead of using explicit *_CHAR codes.
5329 (bidi_resolve_explicit, bidi_resolve_weak):
5330 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
5331 bidirectional text is supported only in multibyte buffers.

5340 were just reseat()'ed to a new position.
5341
5342 * xdisp.c (set_cursor_from_row): Set start and stop points
5343 according to the row's direction when priming the loop that looks

5346 (display_prop_intangible_p): Reimplement to call
5347 handle_display_spec instead of single_display_spec_intangible_p.
5348 Accept 3 additional arguments needed by handle_display_spec.
5349 This fixes incorrect cursor motion across display property with complex
5350 values: lists, `(when COND...)' forms, etc.
5351 (single_display_spec_string_p): Support property values that are
5352 lists with the argument STRING its top-level element.
5353 (display_prop_string_p): Fix the condition for processing a
5354 property that is a list to be consistent with handle_display_spec.

5356 last portion of handle_display_prop.
5357 (compute_display_string_pos): Accept additional argument

5359 value of a `display' property is a "replacing spec".
5360 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
5361 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from

5373 display_prop_intangible_p to its new signature.
5374
5375 * dispextern.h (struct bidi_it): New member frame_window_p.
5376 (bidi_init_it): Update prototypes.
5377 (display_prop_intangible_p): Update prototype.

5389 All callers changed. (Bug#8762)
5390
5391 * gnutls.c: Use Emacs's memory allocators.
5392 Without this change, the gnutls library would invoke malloc etc.
5393 directly, which causes problems on non-SYNC_INPUT hosts, and which
5394 runs afoul of improving memory_full behavior. (Bug#8761)
5395 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
5396 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
5397 xfree instead of the default malloc, realloc, free.
5398 (Fgnutls_boot): No need to check for memory allocation failure,
5399 since xmalloc does that for us.
5400
5401 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
5402 * category.c (hash_get_category_set):

5418 (xpm_put_color_table_h):
5419 * lisp.h (struct Lisp_Hash_Table):
5420 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
5421 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
5422 for hashes and hash indexes, instead of 'unsigned' and 'int'.
5423 * alloc.c (allocate_vectorlike):
5424 Check for overflow in vector size calculations.
5425 * ccl.c (ccl_driver):
5426 Check for overflow when converting EMACS_INT to int.
5427 * fns.c, image.c: Remove unnecessary static decls that would otherwise
5428 need to be updated by these changes.
5429 * fns.c (make_hash_table, maybe_resize_hash_table):
5430 Check for integer overflow with large hash tables.
5431 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
5432 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
5433 (SXHASH_REDUCE): New macro.
5434 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
5435 Use it instead of discarding useful hash info with large hash values.
5436 (sxhash_float): New function.
5437 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
5438 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
5439 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
5440 Rewrite to use FIXNUM_BITS, as this simplifies things.
5441 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
5442 Adjust signatures to match updated version of code.
5443 (consing_since_gc): Now EMACS_INT, since a single hash table can
5444 use more than INT_MAX bytes.

5447
5448 Make it possible to build with GCC-4.6+ -O2 -flto.
5449
5450 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
5451
5452 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
5453
5454 * minibuf.c (get_minibuffer, read_minibuf_unwind):
5455 Call minibuffer-inactive-mode.
5456
5457 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
5458
5459 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
5460 Update dependencies.
5461
5462 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
5463
5464 * data.c (init_data): Remove code for UTS, this system is not
5465 supported anymore.
5466
5467 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
5468
5469 Don't force ./temacs to start in terminal mode.
5470
5471 * frame.c (make_initial_frame): Initialize faces in all cases, not
5472 only when CANNOT_DUMP is defined.
5473 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
5474
5475 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
5476
5477 * dispnew.c (add_window_display_history): Use const for the string
5478 pointer. Remove declaration, not needed.
5479
5480 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
5481
5482 Use 'inline', not 'INLINE'.
5483 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
5484 * alloc.c, fontset.c (INLINE): Remove.
5485 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
5486 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
5487 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
5488 * gmalloc.c (register_heapinfo): Use inline unconditionally.
5489 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
5490
5491 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
5492
5493 Make it possible to run ./temacs.
5494
5495 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
5496 syms_of_callproc does the same thing. Remove test for
5497 "initialized", do it in the caller.
5498 * emacs.c (main): Avoid calling set_initial_environment when dumping.
5499
5500 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
5501
5502 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
5503 (read_minibuf): Use get_minibuffer.
5504 (syms_of_minibuf): Use DEFSYM.
5505 (Qmetadata): New var.
5506 * data.c (Qbuffer): Don't make it static.
5507 (syms_of_data): Use DEFSYM.
5508
5509 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
5510
5511 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
5512 (CCL_CODE_MIN): New macro.
5513
5514 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
5515
5516 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
5517
5518 * eval.c (Qdebug): Now static.
5519 * lisp.h (Qdebug): Remove decl. This reverts a part of the
5520 2011-04-26T11:26:05Z!dan.colascione@gmail.com that inadvertently undid part of
5521 2011-04-14T06:48:41Z!eggert@cs.ucla.edu.
5522
5523 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
5524
5525 * image.c: Various fixes to ImageMagick code comments.
5526 (Fimagemagick_types): Doc fix.
5527
5528 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
5529
5530 Minor fixes prompted by GCC 4.6.0 warnings.
5531
5532 * xselect.c (converted_selections, conversion_fail_tag): Now static.
5533
5534 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
5535 (x_clipboard_manager_save_all): Move extern decl to ...
5536 * xterm.h: ... here, so that it can be checked for consistency.
5537
5538 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
5539
5540 * xselect.c (x_clipboard_manager_save_frame)
5541 (x_clipboard_manager_save_all): New functions.
5542 (Fx_clipboard_manager_save): Lisp function deleted.
5543
5544 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
5545 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
5546
5547 * xterm.h: Update prototype.
5548
5549 2011-05-28 William Xu <william.xwl@gmail.com>
5550
5551 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
5552 exiting (Bug#8239).
5553
5554 2011-05-28 Jim Meyering <meyering@redhat.com>
5555
5556 Avoid a sign-extension bug in crypto_hash_function.
5557 * fns.c (to_uchar): Define.
5558 (crypto_hash_function): Use it to convert some newly-signed
5559 variables to unsigned, to avoid sign-extension bugs. For example,
5560 without this change, (md5 "truc") would evaluate to
5561 45723a2aff78ff4fff7fff1114760e62 rather than the expected
5562 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
5563 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
5564
5565 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
5566
5567 Integer overflow fixes.
5568
5569 * dbusbind.c: Serial number integer overflow fixes.
5570 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
5571 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
5572 to hold a serial number that is too large for a fixnum.
5573 (Fdbus_method_return_internal, Fdbus_method_error_internal):
5574 Check for serial numbers out of range. Decode any serial number
5575 that was so large that it became a float. (Bug#8722)
5576
5577 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
5578 (Fdbus_call_method, Fdbus_call_method_asynchronously):
5579 Use XFASTINT rather than XUINT when numbers are nonnegative.
5580 (xd_append_arg, Fdbus_method_return_internal):
5581 (Fdbus_method_error_internal): Likewise. Also, for unsigned
5582 arguments, check that Lisp number is nonnegative, rather than
5583 silently wrapping negative numbers around. (Bug#8722)
5584 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
5585 (Bug#8722)
5586
5587 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
5588
5589 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
5590
5591 ccl: add integer overflow checks
5592 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
5593 (IN_INT_RANGE): New macros.
5594 (ccl_driver): Use them to check for integer overflow when
5595 decoding a CCL program. Many of the new checks are whether XINT (x)
5596 fits in int; it doesn't always, on 64-bit hosts. The new version
5597 doesn't catch all possible integer overflows, but it's an
5598 improvement. (Bug#8719)
5599
5600 * alloc.c (make_event_array): Use XINT, not XUINT.
5601 There's no need for unsigned here.
5602
5603 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
5604 This follows up to the 2011-05-06 change that substituted uintptr_t
5605 for EMACS_INT. This case wasn't caught back then.
5606
5607 Rework Fformat to avoid integer overflow issues.
5608 * editfns.c: Include <float.h> unconditionally, as it's everywhere
5609 now (part of C89). Include <verify.h>.
5610 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
5611 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
5612 (Fformat): Avoid the prepass trying to compute sizes; it was only
5613 approximate and thus did not catch overflow reliably. Instead, walk
5614 through the format just once, formatting and computing sizes as we go,
5615 checking for integer overflow at every step, and allocating a larger
5616 buffer as needed. Keep track separately whether the format is
5617 multibyte. Keep only the most-recently calculated precision, rather
5618 than them all. Record whether each argument has been converted to
5619 string. Use EMACS_INT, not int, for byte and char and arg counts.
5620 Support field widths and precisions larger than INT_MAX. Avoid
5621 sprintf's undefined behavior with conversion specifications such as %#d
5622 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
5623 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
5624 formatting out-of-range floating point numbers with int
5625 formats. (Bug#8668)
5626
5627 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
5628
5629 * data.c: Avoid integer truncation in expressions involving floats.
5630 * data.c: Include <intprops.h>.
5631 (arith_driver): When there's an integer overflow in an expression
5632 involving floating point, convert the integers to floating point
5633 so that the resulting value does not suffer from catastrophic
5634 integer truncation. For example, on a 64-bit host (* 4
5635 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
5636 Do not rely on undefined behavior after integer overflow.
5637
5638 merge count_size_as_multibyte, parse_str_to_multibyte
5639 * character.c, character.h (count_size_as_multibyte):
5640 Rename from parse_str_to_multibyte; all uses changed.
5641 Check for integer overflow.
5642 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
5643 since it's now a duplicate of the other. This is more of
5644 a character than a buffer op, so better that it's in character.c.
5645 * fns.c, print.c: Adjust to above changes.
5646
5647 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
5648
5649 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
5650
5651 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
5652
5653 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
5654 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
5655 (x_clipboard_manager_save): Now static.
5656 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
5657
5658 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
5659 (crypto_hash_function): Now static.
5660 Fix pointer signedness problems. Avoid unnecessary initializations.
5661
5662 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
5663
5664 * termhooks.h (Vselection_alist): Make it terminal-local.
5665
5666 * terminal.c (create_terminal): Initialize it.
5667
5668 * xselect.c: Support for clipboard managers.
5669 (Vselection_alist): Move to termhooks.h as terminal-local var.
5670 (LOCAL_SELECTION): New macro.
5671 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
5672 (symbol_to_x_atom): Remove gratuitous arg.
5673 (x_handle_selection_request, lisp_data_to_selection_data)
5674 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
5675 (x_own_selection, x_get_local_selection, x_convert_selection):
5676 New arg, specifying work frame. Use terminal-local Vselection_alist.
5677 (some_frame_on_display): Delete unused function.
5678 (Fx_own_selection_internal, Fx_get_selection_internal)
5679 (Fx_disown_selection_internal, Fx_selection_owner_p)
5680 (Fx_selection_exists_p): New optional frame arg.
5681 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
5682 (x_handle_selection_clear): Don't treat other terminals with the
5683 same keyboard specially. Use the terminal-local Vselection_alist.
5684 (x_clear_frame_selections): Use Frun_hook_with_args.
5685
5686 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
5687
5688 * xterm.h: Add support for those atoms.
5689
5690 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
5691
5692 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
5693 (converted_selections, conversion_fail_tag): New global variables.
5694 (x_selection_request_lisp_error): Free the above.
5695 (x_get_local_selection): Remove unnecessary code.
5696 (x_reply_selection_request): Args changed; handle arbitrary array
5697 of converted selections stored in converted_selections.
5698 Separate the XChangeProperty and SelectionNotify steps.
5699 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
5700 (x_convert_selection): New function.
5701 (x_handle_selection_event): Simplify.
5702 (x_get_foreign_selection): Don't ignore incoming requests while
5703 waiting for an answer; this will fail when we implement
5704 SAVE_TARGETS, and seems unnecessary anyway.
5705 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
5706 (Vx_sent_selection_functions): Doc fix.
5707
5708 2011-05-26 Leo Liu <sdl.web@gmail.com>
5709
5710 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
5711
5712 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5713
5714 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
5715
5716 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
5717 for fringe update if it has periodic bitmap.
5718 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
5719 and fringe_bitmap_periodic_p.
5720
5721 * fringe.c (get_fringe_bitmap_data): New function.
5722 (draw_fringe_bitmap_1, update_window_fringes): Use it.
5723 (update_window_fringes): Record periodicity of fringe bitmap in glyph
5724 row. Mark glyph row for fringe update if periodicity changed.
5725
5726 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
5727 for fringe update unless it has periodic bitmap.
5728
5729 2011-05-25 Kenichi Handa <handa@m17n.org>
5730
5731 * xdisp.c (get_next_display_element): Set correct it->face_id for
5732 a static composition.
5733
5734 2011-05-24 Leo Liu <sdl.web@gmail.com>
5735
5736 * deps.mk (fns.o):
5737 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
5738
5739 * fns.c (crypto_hash_function, Fsha1): New function.
5740 (Fmd5): Use crypto_hash_function.
5741 (syms_of_fns): Add Ssha1.
5742
5743 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
5744
5745 * gnutls.c: Remove unused macros.
5746 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
5747 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
5748 Remove macros that are defined and never used.
5749 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
5750
5751 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
5752
5753 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
5754 (Fx_get_selection_internal): Minor cleanup.
5755 (Fx_own_selection_internal): Rename arguments for consistency with
5756 select.el.
5757
5758 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
5759
5760 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
5761
5762 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
5763
5764 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
5765
5766 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5767
5768 * dispnew.c (scrolling_window): Don't exclude the case that the
5769 last enabled row in the desired matrix touches the bottom boundary.
5770
5771 2011-05-21 Glenn Morris <rgm@gnu.org>
5772
5773 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
5774 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
5775 and add some more files.
5776
5777 2011-05-20 Eli Zaretskii <eliz@gnu.org>
5778
5779 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
5780 report_file_error introduced by the change from 2011-05-07.
5781
5782 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
5783
5784 * systime.h (Time): Define only if emacs is defined.
5785 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
5786 where the include path doesn't have X11/X.h by default. See
5787 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
5788
5789 2011-05-20 Kenichi Handa <handa@m17n.org>
5790
5791 * composite.c (find_automatic_composition): Fix previous change.
5792
5793 2011-05-20 Glenn Morris <rgm@gnu.org>
5794
5795 * lisp.mk: New file, split from Makefile.in.
5796 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
5797 (shortlisp): Remove.
5798 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
5799
5800 2011-05-19 Glenn Morris <rgm@gnu.org>
5801
5802 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
5803 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
5804 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
5805 (lisp): Set the order to that of loadup.el.
5806 (shortlisp): Make it a copy of $lisp.
5807 (SOME_MACHINE_LISP): Remove.
5808 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
5809 Use just $shortlisp, not $SOME_MACHINE_LISP too.
5810
5811 2011-05-18 Kenichi Handa <handa@m17n.org>
5812
5813 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
5814 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
5815 (find_automatic_composition): Mostly rewrite for efficiency.
5816
5817 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
5818
5819 * makefile.w32-in: Update dependencies.
5820
5821 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
5822
5823 * menu.c: Include limits.h (fixes the MS-Windows build broken by
5824 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
5825
5826 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
5827
5828 Fix some integer overflow issues, such as string length overflow.
5829
5830 * insdel.c (count_size_as_multibyte): Check for string overflow.
5831
5832 * character.c (lisp_string_width): Check for string overflow.
5833 Use EMACS_INT, not int, for string indexes and lengths; in
5834 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
5835 the resulting string length overflows an EMACS_INT; instead,
5836 report a string overflow if no precision given. When checking for
5837 precision exhaustion, use a check that cannot possibly have
5838 integer overflow. (Bug#8675)
5839 * character.h (lisp_string_width): Adjust to new signature.
5840
5841 * alloc.c (string_overflow): New function.
5842 (Fmake_string): Use it. This doesn't change behavior, but saves
5843 a few bytes and will simplify future changes.
5844 * character.c (string_escape_byte8): Likewise.
5845 * lisp.h (string_overflow): New decl.
5846
5847 Fixups, following up to the user-interface timestamp change.
5848 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
5849 for UI timestamps, instead of unsigned long.
5850 * msdos.c (mouse_get_pos): Likewise.
5851 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
5852 * w32gui.h (Time): Define by including "systime.h" rather than by
5853 declaring it ourselves. (Bug#8664)
5854
5855 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
5856 * image.c (clear_image_cache): Likewise.
5857
5858 * term.c (term_mouse_position): Don't assume time_t wraparound.
5859
5860 Be more systematic about user-interface timestamps.
5861 Before, the code sometimes used 'Time', sometimes 'unsigned long',
5862 and sometimes 'EMACS_UINT', to represent these timestamps.
5863 This change causes it to use 'Time' uniformly, as that's what X uses.
5864 This makes the code easier to follow, and makes it easier to catch
5865 integer overflow bugs such as Bug#8664.
5866 * frame.c (Fmouse_position, Fmouse_pixel_position):
5867 Use Time, not unsigned long, for user-interface timestamps.
5868 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
5869 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
5870 * keyboard.h (last_event_timestamp): Likewise.
5871 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
5872 * menu.h (xmenu_show): Likewise.
5873 * term.c (term_mouse_position): Likewise.
5874 * termhooks.h (struct input_event.timestamp): Likewise.
5875 (struct terminal.mouse_position_hook): Likewise.
5876 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
5877 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
5878 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
5879 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
5880 what it was before.
5881 * menu.h, termhooks.h: Include "systime.h", for Time.
5882
5883 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
5884 Don't assume that the difference between two unsigned long values
5885 can fit into an integer. At this point, we know button_down_time
5886 <= event->timestamp, so the difference must be nonnegative, so
5887 there's no need to cast the result if double-click-time is
5888 nonnegative, as it should be; check that it's nonnegative, just in
5889 case. This bug is triggered when events are more than 2**31 ms
5890 apart (about 25 days). (Bug#8664)
5891
5892 * xselect.c (last_event_timestamp): Remove duplicate decl.
5893 (x_own_selection): Remove needless cast to unsigned long.
5894
5895 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
5896 that always fit in int. Use a sentinel instead of a counter, to
5897 avoid a temp and to allay GCC's concerns about possible int overflow.
5898 * frame.h (struct frame): Use int for menu_bar_items_used
5899 instead of EMACS_INT, since it always fits in int.
5900
5901 * menu.c (grow_menu_items): Check for int overflow.
5902
5903 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
5904
5905 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
5906 Before, the code was not consistent. These values cannot exceed
5907 2**31 - 1 so there's no need to make them unsigned.
5908 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
5909 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
5910 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
5911 as modifiers.
5912 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
5913
5914 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
5915 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
5916 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
5917 presumably because the widths might not match.
5918
5919 * window.c (size_window): Avoid needless test at loop start.
5920
5921 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
5922
5923 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
5924
5925 2011-05-12 Drew Adams <drew.adams@oracle.com>
5926
5927 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
5928
5929 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
5930
5931 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
5932 `width' to `bar_area_x' and `bar_area_width', respectively.
5933 (x_scroll_run): Take account of fringe background extension.
5934
5935 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
5936 Rename local vars `left' and `width' to `bar_area_x' and
5937 `bar_area_width', respectively.
5938 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
5939 background extension.
5940
5941 2011-05-10 Jim Meyering <meyering@redhat.com>
5942
5943 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
5944
5945 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
5946
5947 * image.c (Finit_image_library): Return t for built-in image types,
5948 like pbm and xbm. (Bug#8640)
5949
5950 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
5951
5952 * w32menu.c (set_frame_menubar): Fix submenu allocation.
5953
5954 2011-05-07 Eli Zaretskii <eliz@gnu.org>
5955
5956 * w32console.c (Fset_screen_color): Doc fix.
5957 (Fget_screen_color): New function.
5958 (syms_of_ntterm): Defsubr it.
5959
5960 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
5961 unlink the temporary file if Fcall_process didn't create it in the
5962 first place.
5963 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
5964 child process will be redirected to a file specified with `:file'.
5965 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
5966 cue to call_process_cleanup not to close that handle.
5967
5968 2011-05-07 Ben Key <bkey76@gmail.com>
5969
5970 * makefile.w32-in: The bootstrap-temacs rule now makes use of
5971 one of two shell specific rules, either bootstrap-temacs-CMD or
5972 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
5973 to the previous implementation of the bootstrap-temacs rule.
5974 The bootstrap-temacs-CMD rule is similar to the previous
5975 implementation of the bootstrap-temacs rule except that it
5976 makes use of the ESC_CFLAGS variable instead of the CFLAGS
5977 variable.
5978
5979 These changes, along with some changes to nt/configure.bat,
5980 nt/gmake.defs, and nt/nmake.defs, are required to extend my
5981 earlier fix to add support for --cflags and --ldflags options
5982 that include quotes so that it works whether make uses cmd or
5983 sh as the shell.
5984
5985 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
5986
5987 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
5988 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
5989 is a constant.
5990 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
5991 a string. Handle both cases.
5992 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
5993 (Fdbus_register_method): Use Qinvalid_function.
5994
5995 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
5996
5997 * makefile.w32-in: Update dependencies.
5998 (LISP_H): Add inttypes.h and stdin.h.
5999 (PROCESS_H): Add unistd.h.
6000
6001 2011-05-06 Eli Zaretskii <eliz@gnu.org>
6002
6003 * lread.c: Include limits.h (fixes the MS-Windows build broken by
6004 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
6005
6006 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
6007
6008 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
6009
6010 * term.c (vfatal): Remove stray call to va_end.
6011 It's not needed and the C Standard doesn't allow it here anyway.
6012
6013 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
6014 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
6015
6016 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
6017 bytes.
6018
6019 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
6020
6021 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
6022
6023 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
6024
6025 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
6026
6027 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
6028
6029 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
6030 * charset.c (Fdefine_charset_internal): Don't initialize
6031 charset.code_space[15]. The value was garbage, on hosts with
6032 32-bit int (Bug#8600).
6033
6034 * lread.c (read_integer): Be more consistent with string-to-number.
6035 Use string_to_number to do the actual conversion; this avoids
6036 rounding errors and fixes some other screwups. Without this fix,
6037 for example, #x1fffffffffffffff was misread as -2305843009213693952.
6038 (digit_to_number): Move earlier, for benefit of read_integer.
6039 Return -1 if the digit is out of range for the base, -2 if it is
6040 not a digit in any supported base. (Bug#8602)
6041
6042 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
6043
6044 * dispnew.c (scrolling_window): Return 1 if we scrolled,
6045 to match comment at start of function. This also removes a
6046 GCC warning about overflow in a 32+64-bit port.
6047
6048 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
6049
6050 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
6051 Reported by Stefan Monnier in
6052 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
6053 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
6054 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
6055
6056 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
6057 (EMACS_UINTPTR): Likewise, with uintptr_t.
6058
6059 * lisp.h: Prefer 64-bit EMACS_INT if available.
6060 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
6061 on 32-bit hosts that have 64-bit int, so that they can access
6062 large files.
6063 However, temporarily disable this change unless the temporary
6064 symbol WIDE_EMACS_INT is defined.
6065
6066 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
6067
6068 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
6069 This removes an assumption that EMACS_INT and long are the same
6070 width as pointers. The assumption is true for Emacs porting targets
6071 now, but we want to make other targets possible.
6072 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
6073 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
6074 In the rest of the code, change types of integers that hold casted
6075 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
6076 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
6077 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
6078 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
6079 No need to cast type when ORing.
6080 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
6081 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
6082 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
6083 assume EMACS_INT is the same width as char *.
6084 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
6085 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
6086 Remove no-longer-needed casts.
6087 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
6088 (xg_tool_bar_help_callback, xg_make_tool_item):
6089 Use EMACS_INTPTR to hold an integer
6090 that will be cast to void *; this can avoid a GCC warning
6091 if EMACS_INT is not the same width as void *.
6092 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
6093 * xdisp.c (display_echo_area_1, resize_mini_window_1):
6094 (current_message_1, set_message_1):
6095 Use a local to convert to proper width without a cast.
6096 * xmenu.c (dialog_selection_callback): Likewise.
6097
6098 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
6099 Also, don't assume VALBITS / RAND_BITS is less than 5,
6100 and don't rely on undefined behavior when shifting a 1 left into
6101 the sign bit.
6102 * lisp.h (get_random): Change signature to match.
6103
6104 * lread.c (hash_string): Use size_t, not int, for hash computation.
6105 Normally we prefer signed values; but hashing is special, because
6106 it's better to use unsigned division on hash table sizes so that
6107 the remainder is nonnegative. Also, size_t is the natural width
6108 for hashing into memory. The previous code used 'int', which doesn't
6109 retain enough info to hash well into very large tables.
6110 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
6111
6112 * dbusbind.c: Don't possibly lose pointer info when converting.
6113 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
6114 Use XPNTR rather than XHASH, so that the high-order bits of
6115 the pointer aren't lost when converting through void *.
6116
6117 * eval.c (Fautoload): Don't double-shift a pointer.
6118
6119 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
6120
6121 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
6122
6123 * gnutls.c (DEF_GNUTLS_FN):
6124 * image.c (DEF_IMGLIB_FN): Make function pointers static.
6125
6126 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
6127
6128 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
6129 marker. (Bug#8610)
6130
6131 2011-05-05 Eli Zaretskii <eliz@gnu.org>
6132
6133 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
6134 New version that can reserve upto 2GB of heap space.
6135
6136 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
6137
6138 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).

6144
6145 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
6146
6147 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
6148 Update dependencies.
6149
6150 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
6151
6152 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
6153 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
6154 Remove unused parameter `fildes'.
6155 * process.c (read_process_output, send_process): Don't pass it.
6156
6157 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
6158
6159 Fix previous change: the library cache is defined in w32.c.
6160 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
6161 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
6162
6163 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
6164
6165 Implement dynamic loading of GnuTLS on Windows.
6166
6167 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
6168 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
6169 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
6170 Declare.
6171
6172 * gnutls.c (Qgnutls_dll): Define.
6173 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
6174 (gnutls_*): Declare function pointers.
6175 (init_gnutls_functions): New function to initialize function pointers.
6176 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
6177 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
6178 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
6179 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
6180 (emacs_gnutls_write, emacs_gnutls_read)
6181 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
6182 (Fgnutls_available_p): New function.
6183 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
6184 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
6185 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
6186
6187 * image.c: Include w32.h.
6188 (Vimage_type_cache): Delete.
6189 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
6190 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
6191 (w32_delayed_load): Move to w32.c.
6192
6193 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
6194
6195 * w32.c (QCloaded_from, Vlibrary_cache): Define.
6196 (w32_delayed_load): Move from image.c. When loading a library, record
6197 its filename in the :loaded-from property of the library id.
6198 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
6199 Initialize and staticpro them.
6200 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
6201
6202 * process.c: Include lisp.h before w32.h, not after.
6203 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
6204 instead of gnutls_record_check_pending.
6205
6206 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
6207

6212 as passed in.
6213
6214 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>

6224
6225 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
6226 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)
6227 (Qgnutls_e_invalid_session, Qgnutls_e_not_ready_for_handshake)
6228 (gnutls_global_initialized, Qgnutls_bootprop_priority)
6229 (Qgnutls_bootprop_trustfiles, Qgnutls_bootprop_keyfiles)
6230 (Qgnutls_bootprop_callbacks, Qgnutls_bootprop_loglevel)
6231 (Qgnutls_bootprop_hostname, Qgnutls_bootprop_verify_flags)
6232 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
6233 (Qgnutls_bootprop_callbacks_verify): Make static.
6234
6235 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
6236
6237 * callproc.c: Indentation fixup.
6238
6239 * sysdep.c (wait_for_termination_1): Make static.
6240 (wait_for_termination, interruptible_wait_for_termination):
6241 Move after wait_for_termination_1.
6242
6243 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
6244
6245 * sysdep.c (interruptible_wait_for_termination): New function
6246 which is like wait_for_termination, but allows keyboard
6247 interruptions.
6248
6249 * callproc.c (Fcall_process): Add (:file "file") as an option for
6250 the STDOUT buffer.
6251 (Fcall_process_region): Ditto.
6252

6255 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
6256 rather than `XVECTOR (FOO)->size'.
6257
6258 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
6259 inttypes.h, as a gnulib replacement is used if it not available in
6260 system headers.
6261

6266 of MOST_POSITIVE_FIXNUM. (Bug#8528)
6267
6268 * coding.c (coding_alloc_by_realloc): Error out if destination
6269 will grow beyond MOST_POSITIVE_FIXNUM.
6270 (decode_coding_emacs_mule): Abort if there isn't enough place in
6271 charbuf for the composition carryover bytes. Reserve an extra
6272 space for up to 2 characters produced in a loop.
6273 (decode_coding_iso_2022): Abort if there isn't enough place in
6274 charbuf for the composition carryover bytes.

6276 2011-04-21 Eli Zaretskii <eliz@gnu.org>
6277
6278 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
6279 aborting when %lld or %lll format is passed.
6280 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
6281 %llo or %llx format is passed. (Bug#8545)
6282
6283 * window.c (window_scroll_line_based): Use a marker instead of
6284 simple variables to record original value of point. (Bug#7952)
6285
6286 * doprnt.c (doprnt): Fix the case where a multibyte sequence
6287 produced by %s or %c overflows available buffer space. (Bug#8545)
6288
6289 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
6290
6291 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
6292 (SIZE_MAX): Move defn after all includes, as they might #define it.
6293
6294 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
6295
6296 * w32.c (init_environment): Warn about defaulting HOME to C:\.
6297
6298 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
6299
6300 * keyboard.c (Qdelayed_warnings_hook): Define.
6301 (command_loop_1): Run `delayed-warnings-hook'
6302 if Vdelayed_warnings_list is non-nil.
6303 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
6304 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
6305
6306 2011-04-28 Eli Zaretskii <eliz@gnu.org>
6307
6308 * doprnt.c (doprnt): Don't return value smaller than the buffer
6309 size if the message was truncated. (Bug#8545).
6310
6311 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
6312
6313 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
6314 (Fx_window_property): #if-0 the whole functions, not just the bodies.
6315
6316 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
6317
6318 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
6319
6320 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
6321
6322 * makefile.w32-in: Update dependencies.
6323
6324 2011-04-27 Eli Zaretskii <eliz@gnu.org>
6325
6326 Improve `doprnt' and its usage. (Bug#8545)
6327 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
6328 `format_end'. Remove support for %l as a conversion specifier.
6329 Don't use xrealloc. Improve diagnostics when the %l size modifier
6330 is used. Update the commentary.
6331
6332 * eval.c (verror): Simplify calculation of size_t.
6333
6334 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
6335 messages.
6336
6337 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
6338
6339 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
6340 change.
6341
6342 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
6343
6344 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
6345 This makes this file independent of the recent pseudovector change.
6346
6347 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
6348
6349 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
6350
6351 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
6352 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
6353 Remove unused local.
6354 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
6355
6356 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
6357 GCC 4.6.0 optimizes based on type-based alias analysis.
6358 For example, if b is of type struct buffer * and v of type struct
6359 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
6360 != &v->size, and therefore "v->size = 1; b->size = 2; return
6361 v->size;" must therefore return 1. This assumption is incorrect
6362 for Emacs, since it type-puns struct Lisp_Vector * with many other
6363 types. To fix this problem, this patch adds a new type struct
6364 vectorlike_header that documents the constraints on layout of vectors
6365 and pseudovectors, and helps optimizing compilers not get fooled
6366 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
6367 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
6368 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
6369 the size member.
6370 (XSETPVECTYPE): Rewrite in terms of new macro.
6371 (XSETPVECTYPESIZE): New macro, specifying both type and size.
6372 This is a bit clearer, and further avoids the possibility of
6373 undesirable aliasing.
6374 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
6375 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
6376 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
6377 since Lisp_Subr is a special case (no "next" field).
6378 (ASIZE): Now uses header.size rather than size.
6379 All previous uses of XVECTOR (foo)->size replaced to use this macro,
6380 to avoid the hassle of writing XVECTOR (foo)->header.size.
6381 (struct vectorlike_header): New type.
6382 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
6383 object, to help avoid aliasing.
6384 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
6385 (SUBRP): Likewise, since Lisp_Subr is a special case.
6386 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
6387 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
6388 (struct Lisp_Hash_Table): Combine first two members into a single
6389 struct vectorlike_header member. All uses of "size" and "next" members
6390 changed to be "header.size" and "header.next".
6391 * buffer.h (struct buffer): Likewise.
6392 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
6393 * frame.h (struct frame): Likewise.
6394 * process.h (struct Lisp_Process): Likewise.
6395 * termhooks.h (struct terminal): Likewise.
6396 * window.c (struct save_window_data, struct saved_window): Likewise.
6397 * window.h (struct window): Likewise.
6398 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
6399 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
6400 * buffer.c (init_buffer_once): Likewise.
6401 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
6402 special case.
6403 * process.c (Fformat_network_address): Use local var for size,
6404 for brevity.
6405
6406 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
6407
6408 Make the Lisp reader and string-to-float more consistent (Bug#8525)
6409 * data.c (atof): Remove decl; no longer used or needed.
6410 (digit_to_number): Move to lread.c.
6411 (Fstring_to_number): Use new string_to_number function, to be
6412 consistent with how the Lisp reader treats infinities and NaNs.
6413 Do not assume that floating-point numbers represent EMACS_INT
6414 without losing information; this is not true on most 64-bit hosts.
6415 Avoid double-rounding errors, by insisting on integers when
6416 parsing non-base-10 numbers, as the documentation specifies.
6417 * lisp.h (string_to_number): New decl, replacing ...
6418 (isfloat_string): Remove.
6419 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
6420 (read1): Do not accept +. and -. as integers; this
6421 appears to have been a coding error. Similarly, do not accept
6422 strings like +-1e0 as floating point numbers. Do not report
6423 overflow for integer overflows unless the base is not 10 which
6424 means we have no simple and reliable way to continue.
6425 Break out the floating-point parsing into a new
6426 function string_to_number, so that Fstring_to_number parses
6427 floating point numbers consistently with the Lisp reader.
6428 (digit_to_number): Move here from data.c. Make it static inline.
6429 (E_CHAR, EXP_INT): Remove, replacing with ...
6430 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
6431 (string_to_number): New function, replacing isfloat_string.
6432 This function checks for valid syntax and produces the resulting
6433 Lisp float number too. Rework it so that string-to-number
6434 no longer mishandles examples like "1.0e+". Use strtoumax,
6435 so that overflow for non-base-10 numbers is reported only when
6436 there's no portable and simple way to convert to floating point.
6437
6438 * textprop.c (set_text_properties_1): Rewrite for clarity,
6439 and to avoid GCC warning about integer overflow.
6440
6441 * intervals.h (struct interval): Use EMACS_INT for members
6442 where EMACS_UINT might cause problems. See
6443 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
6444 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
6445 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
6446 All uses changed.
6447 (offset_intervals): Tell GCC not to worry about length overflow
6448 when negating a negative length.
6449
6450 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
6451 (overrun_check_free): Likewise.
6452
6453 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
6454 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
6455 word size.
6456
6457 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
6458 (gnutls_make_error): Rename local to avoid shadowing.
6459 (gnutls_emacs_global_deinit): ifdef out; not used.
6460 (Fgnutls_boot): Use const for pointer to readonly storage.
6461 Comment out unused local. Fix pointer signedness problems.
6462
6463 * lread.c (openp): Don't stuff size_t into an 'int'.
6464 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
6465 about possible signed overflow.
6466
6467 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
6468 (GDK_KEY_g): Don't define if already defined.
6469 (xg_prepare_tooltip): Avoid pointer signedness problem.
6470 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
6471
6472 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
6473 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
6474
6475 * xfns.c (Fx_window_property): Simplify a bit,
6476 to make a bit faster and to avoid GCC 4.6.0 warning.
6477 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
6478
6479 * fns.c (internal_equal): Don't assume size_t fits in int.
6480
6481 * alloc.c (compact_small_strings): Tighten assertion a little.
6482
6483 Replace pEd with more-general pI, and fix some printf arg casts.
6484 * lisp.h (pI): New macro, generalizing old pEd macro to other
6485 conversion specifiers. For example, use "...%"pI"d..." rather
6486 than "...%"pEd"...".
6487 (pEd): Remove. All uses replaced with similar uses of pI.
6488 * src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h: Likewise.
6489 * alloc.c (check_pure_size): Don't overflow by converting size to int.
6490 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
6491 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
6492 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
6493 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
6494 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
6495 64-bit hosts.
6496 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
6497 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
6498 * print.c (safe_debug_print, print_object): Likewise.
6499 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
6500 to int.
6501 Use pI instead of if-then-else-abort. Use %p to avoid casts,
6502 avoiding the 0 flag, which is not portable.
6503 * process.c (Fmake_network_process): Use pI to avoid cast.
6504 * region-cache.c (pp_cache): Likewise.
6505 * xdisp.c (decode_mode_spec): Likewise.
6506 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
6507 behavior on 64-bit hosts with printf arg.
6508 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
6509 (x_stop_queuing_selection_requests): Likewise.
6510 (x_get_window_property): Don't truncate byte count to an 'int'
6511 when tracing.
6512
6513 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
6514 here, since it parses constructs like leading '-' and spaces,
6515 which are not wanted; and it overflows with large numbers.
6516 Instead, simply match F[0-9]+, which is what is wanted anyway.
6517
6518 * alloc.c: Remove unportable assumptions about struct layout.
6519 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
6520 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
6521 (allocate_vectorlike, make_pure_vector): Use the new macros,
6522 plus offsetof, to remove unportable assumptions about struct layout.
6523 These assumptions hold on all porting targets that I know of, but
6524 they are not guaranteed, they're easy to remove, and removing them
6525 makes further changes easier.
6526
6527 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
6528 This doesn't fix a bug but makes the code clearer.
6529 (string_overrun_cookie): Now const. Use initializers that
6530 don't formally overflow signed char, to avoid warnings.
6531 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
6532 can cause Emacs to crash when string overrun checking is enabled.
6533 (allocate_buffer): Don't assume sizeof (struct buffer) is a
6534 multiple of sizeof (EMACS_INT); it need not be, if
6535 alignof(EMACS_INT) < sizeof (EMACS_INT).
6536 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
6537
6538 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
6539
6540 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
6541
6542 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
6543
6544 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
6545 supposed to be handshaking. (Bug#8556)
6546 Reported by Paul Eggert <eggert@cs.ucla.edu>.
6547
6548 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
6549
6550 * lisp.h (Qdebug): List symbol.
6551 * eval.c (Qdebug): Restore global linkage.
6552 * keyboard.c (debug-on-event): New variable.
6553 (handle_user_signal): Break into debugger when debug-on-event
6554 matches the current signal symbol.
6555
6556 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
6557
6558 * alloc.c (check_sblock, check_string_bytes)
6559 (check_string_free_list): Convert to standard C.
6560
6561 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
6562
6563 * w32.c (emacs_gnutls_push): Fix typo.
6564
6565 2011-04-25 Eli Zaretskii <eliz@gnu.org>
6566
6567 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
6568 "cast to pointer from integer of different size".
6569
6570 Improve doprnt and its use in verror. (Bug#8545)
6571 * doprnt.c (doprnt): Document the set of format control sequences
6572 supported by the function. Use SAFE_ALLOCA instead of always
6573 using `alloca'.
6574
6575 * eval.c (verror): Don't limit the buffer size at size_max-1, that
6576 is one byte too soon. Don't use xrealloc; instead xfree and
6577 xmalloc anew.
6578
6579 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
6580
6581 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
6582 callbacks stage.
6583
6584 * gnutls.c: Renamed global_initialized to
6585 gnutls_global_initialized. Added internals for the
6586 :verify-hostname-error, :verify-error, and :verify-flags
6587 parameters of `gnutls-boot' and documented those parameters in the
6588 docstring. Start callback support.
6589 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
6590 unless a fatal error occurred. Call gnutls_alert_send_appropriate
6591 on error. Return error code.
6592 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
6593 (emacs_gnutls_read): Likewise.
6594 (Fgnutls_boot): Return handshake error code.
6595 (emacs_gnutls_handle_error): New function.
6596 (wsaerror_to_errno): Likewise.
6597

6600
6601 * w32.c (emacs_gnutls_pull): New function for GnuTLS on Woe32.
6602 (emacs_gnutls_push): Likewise.
6603

6605
6606 * process.c (wait_reading_process_output): Check if GnuTLS
6607 buffered some data internally if no FDs are set for TLS
6608 connections.
6609
6610 * makefile.w32-in (OBJ2): Add gnutls.$(O).
6611 (LIBS): Link to USER_LIBS.

6615
6616 * xdisp.c (handle_single_display_spec): Rename the
6617 display_replaced_before_p argument into display_replaced_p, to
6618 make it consistent with the commentary. Fix typos in the
6619 commentary.
6620
6621 * textprop.c (syms_of_textprop): Remove dead code.
6622 (copy_text_properties): Delete obsolete commentary about an
6623 interface that was deleted long ago. Fix typos in the description
6624 of arguments.
6625
6626 * msdos.c (XMenuActivate, XMenuAddSelection): Adjust argument list
6627 to changes in oldXMenu/XMenu.h from 2011-04-16.
6628 <menu_help_message, prev_menu_help_message>: Constify.
6629 (IT_menu_make_room): menu->help_text is now `const char **';
6630 adjust.
6631
6632 * msdos.h (XMenuActivate, XMenuAddSelection): Adjust prototypes
6633 to changes in oldXMenu/XMenu.h from 2011-04-16.

6635
6636 * xfaces.c <Qunspecified>: Make extern again.
6637
6638 * syntax.c: Include sys/types.h before including regex.h, as
6639 required by Posix.
6640
6641 * doc.c (get_doc_string): Improve the format passed to `error'.
6642
6643 * doprnt.c (doprnt): Improve commentary.
6644
6645 * term.c (init_tty) [MSDOS]: Fix 1st argument to maybe_fatal.
6646
6647 * Makefile.in (TAGS): Depend on $(M_FILE) and $(S_FILE), and scan
6648 them with etags.
6649
6650 * makefile.w32-in (globals.h): Add a dummy recipe, to make any
6651 changes in globals.h immediately force recompilation.
6652 (TAGS): Depend on $(CURDIR)/m/intel386.h and
6653 $(CURDIR)/s/ms-w32.h.
6654 (TAGS-gmake): Scan $(CURDIR)/m/intel386.h and $(CURDIR)/s/ms-w32.h.
6655
6656 * character.c (Fchar_direction): Function deleted.
6657 (syms_of_character): Don't defsubr it.
6658 <char-direction-table>: Deleted.
6659
6660 2011-04-23 Eli Zaretskii <eliz@gnu.org>

7144 * editfns.c, lisp.h (get_operating_system_release): Remove.
7145 * process.c (init_process) [DARWIN_OS]: Do it inline, as it is not
7146 worth the hassle of breaking this out.
7147
7148 * xterm.c: Make symbols static if they're not exported.
7149 (x_raise_frame, x_lower_frame, x_wm_set_window_state):

7255 so that it's not optimized away.
7256 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
7257 * dispextern.h (bidi_dump_cached_states): Remove, since it's
7258 exported only to the debugger.
7259
7260 * atimer.c (alarm_signal_handler, run_all_atimers): Now static.
7261 * atimer.h (run_all_atimers): Remove; not exported.
7262
7263 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.
7264 * font.c (copy_font_spec): Rename from Fcopy_font_spec, since it
7265 was inaccessible from Lisp.

7268
7269 alloc.c: Import and export fewer symbols, and remove unused items.
7270 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
7271 is defined.
7272 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
7273 it's not optimized away by whole-program optimization.

7289 Declare Lisp_Object Q* variables to be 'static' if not exported.
7290 This makes it easier for human readers (and static analyzers)
7291 to see whether these variables are used from other modules.
7292 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:

7303 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
7304
7305 * lisp.h (DEFINE_FUNC): Make sname 'static'.
7306
7307 Make Emacs functions such as Fatom 'static' by default.
7308 This makes it easier for human readers (and static analyzers)
7309 to see whether these functions can be called from other modules.
7310 DEFUN now defines a static function. To make the function external
7311 so that it can be used in other C modules, use the new macro DEFUE.
7312 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
7313 (Finit_image_library):
7314 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
7315 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
7316 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
7317 Remove decls, since these functions are now static.
7318 (Funintern, Fget_internal_run_time): New decls, since these functions
7319 were already external.
7320
7321 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:

7328 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
7329 Mark functions with DEFUE instead of DEFUN,
7330 if they are used in other modules.
7331 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
7332 decls for now-static functions.
7333 * buffer.h (Fdelete_overlay): Remove decl.
7334 * callproc.c (Fgetenv_internal): Mark as internal.
7335 * composite.c (Fremove_list_of_text_properties): Remove decl.

7361

7363
7364 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
7365
7366 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
7367 change. (Bug#8496)
7368
7369 2011-04-13 Eli Zaretskii <eliz@gnu.org>
7370
7371 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
7372 when at ZV. (Bug#8487)
7373
7374 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
7375
7376 * charset.c (Fclear_charset_maps): Use xfree instead of free.
7377 (Bug#8437)
7378 * keyboard.c (parse_tool_bar_item): Likewise.
7379 * sound.c (sound_cleanup, alsa_close): Likewise.

7383
7384 * alloc.c (overrun_check_malloc, overrun_check_realloc)
7385 (overrun_check_free): Protoize.
7386
7387 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
7388
7389 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
7390 since callers should never pass a negative size.
7391 Change the signature to match that of plain 'read' and 'write'; see
7392 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
7393 * lisp.h: Update prototypes of emacs_write and emacs_read.
7394
7395 2011-04-11 Eli Zaretskii <eliz@gnu.org>
7396
7397 * xdisp.c (redisplay_window): Don't try to determine the character
7398 position of the scroll margin if the window start point w->startp
7399 is outside the buffer's accessible region. (Bug#8468)
7400
7401 2011-04-10 Eli Zaretskii <eliz@gnu.org>
7402
7403 Fix write-region and its subroutines for buffers > 2GB.
7404 * fileio.c (a_write, e_write): Modify declaration of arguments and
7405 local variables to support buffers larger than 2GB.
7406 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
7407
7408 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
7409 argument, local variables, and return value.
7410
7411 * lisp.h: Update prototypes of emacs_write and emacs_read.
7412
7413 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
7414
7415 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
7416
7417 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
7418
7419 Fix more problems found by GCC 4.6.0's static checks.
7420
7421 * xdisp.c (vmessage): Use a better test for character truncation.
7422
7423 * charset.c (load_charset_map): <, not <=, for optimization,
7424 and to avoid potential problems with integer overflow.
7425 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
7426 * casetab.c (set_identity, shuffle): Likewise.
7427 * editfns.c (Fformat): Likewise.
7428 * syntax.c (skip_chars): Likewise.
7429
7430 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
7431 This also lets GCC 4.6.0 generate slightly better loop code.
7432
7433 * callint.c (Fcall_interactively): <, not <=, for optimization.
7434 (Fcall_interactively): Count the number of arguments produced,
7435 not the number of arguments given. This is simpler and lets GCC
7436 4.6.0 generate slightly better code.
7437
7438 * ftfont.c: Distingish more carefully between FcChar8 and char.
7439 The previous code passed unsigned char * to a functions like
7440 strlen and xstrcasecmp that expect char *, which does not
7441 conform to the C standard.
7442 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
7443 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
7444 char * when the C standard requires it.
7445
7446 * keyboard.c (read_char): Remove unused var.
7447
7448 * eval.c: Port to Windows vsnprintf (Bug#8435).
7449 Include <limits.h>.
7450 (SIZE_MAX): Define if the headers do not.
7451 (verror): Do not give up if vsnprintf returns a negative count.
7452 Instead, grow the buffer. This ports to Windows vsnprintf, which
7453 does not conform to C99. Problem reported by Eli Zaretskii.
7454 Also, simplify the allocation scheme, by avoiding the need for
7455 calling realloc, and removing the ALLOCATED variable.
7456
7457 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
7458
7459 Remove invocations of doprnt, as Emacs now uses vsnprintf.
7460 But keep the doprint source code for now, as we might revamp it
7461 and use it again (Bug#8435).
7462 * lisp.h (doprnt): Remove.
7463 * Makefile.in (base_obj): Remove doprnt.o.
7464 * deps.mk (doprnt.o): Remove.
7465
7466 error: Print 32- and 64-bit integers portably (Bug#8435).
7467 Without this change, on typical 64-bit hosts error ("...%d...", N)
7468 was used to print both 32- and 64-bit integers N, which relied on
7469 undefined behavior.
7470 * lisp.h, src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h (pEd):
7471 New macro.
7472 * lisp.h (error, verror): Mark as printf-like functions.
7473 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
7474 Report overflow in size calculations when allocating printf buffer.
7475 Do not truncate output string at its first null byte.
7476 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
7477 Truncate the output at a character boundary, since vsnprintf does not
7478 do that.
7479 * charset.c (check_iso_charset_parameter): Convert internal
7480 character to string before calling 'error', since %c now has the
7481 printf meaning.
7482 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int

7626 some unnecessary tests.
7627 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
7628 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
7629 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.

7643 by using the new macro.
7644
7645 * textprop.c (set_text_properties_1): Change while to do-while,
7646 since the condition is always true at first.
7647
7648 * intervals.c (graft_intervals_into_buffer): Mark var as used.

7672
7673 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
7674 (font_score): Avoid potential overflow in diff calculation.
7675
7676 * fns.c (substring_both): Remove var that is set but not used.

7678
7679 * eval.c (funcall_lambda): Rename local to avoid shadowing.
7680
7681 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.

7683 can always succeed if overflow has undefined behavior.
7684
7685 * search.c (boyer_moore, wordify): Remove vars set but not used.
7686 (wordify): Omit three unnecessary tests.
7687

7715
7716 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
7717 that are set but not used.
7718
7719 * xfns.c (make_invisible_cursor): Don't return garbage
7720 if XCreateBitmapFromData fails (Bug#8410).
7721
7722 * xselect.c (x_get_local_selection, x_handle_property_notify):
7723 Remove vars that are set but not used.

7732 Check for overflow.
7733
7734 * xfaces.c (realize_named_face): Remove vars that are set but not used.
7735 (map_tty_color) [!defined MSDOS]: Likewise.
7736
7737 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
7738
7739 * coding.c: Remove vars that are set but not used.
7740 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
7741 All callers changed.
7742 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
7743 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
7744 (decode_coding_charset): Remove vars that are set but not used.

7751 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
7752 The gnulib version avoids calling malloc in the usual case,
7753 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
7754 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
7755 * filelock.c (current_lock_owner): Likewise.
7756 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
7757 * sysdep.c: Include allocator.h, careadlinkat.h.
7758 (emacs_no_realloc_allocator): New static constant.
7759 (emacs_readlink): New function.
7760 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
7761 ../lib/careadlinkat.h.

7764
7765 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
7766 first non-nil return value).
7767
7768 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
7769
7770 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
7771 if not defined (Bug#8403).
7772
7773 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
7774
7775 * xdisp.c (display_count_lines): Remove parameter `start',
7776 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.

7822 * image.c (parse_image_spec): Use Ffunctionp.
7823
7824 * fns.c (concat, mapcar1): Accept byte-code-functions.
7825
7826 * eval.c (Fsetq): Handle lexical vars.
7827 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
7828 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
7829 (FletX, Flet): Obey lexical binding.
7830 (Fcommandp): Handle closures.
7831 (Feval): New `lexical' arg.
7832 (eval_sub): New function extracted from Feval. Use it almost
7833 everywhere where Feval was used. Look up vars in lexical env.
7834 Handle closures.
7835 (Ffunctionp): Move from subr.el.
7836 (Ffuncall): Handle closures.
7837 (apply_lambda): Remove `eval_flags'.
7838 (funcall_lambda): Handle closures and new byte-code-functions.
7839 (Fspecial_variable_p): New function.
7840 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
7841 but without exporting it to Lisp.
7842
7843 * doc.c (Fdocumentation, store_function_docstring):
7844 * data.c (Finteractive_form): Handle closures.
7845
7846 * callint.c (Fcall_interactively): Preserve lexical-binding mode for

7865 (try_scrolling): Use it when setting scroll_limit.
7866 Limit scrolling to 100 screen lines.
7867 (redisplay_window): Even when falling back on "recentering",
7868 position point in the window according to scroll-conservatively,
7869 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
7870
7871 (try_scrolling): When point is above the window, allow searching
7872 as far as scroll_max, or one screenful, to compute vertical
7873 distance from PT to the scroll margin position. This prevents
7874 try_scrolling from unnecessarily failing when
7875 scroll-conservatively is set to a value slightly larger than the
7876 window height. Clean up the case of PT below the margin at bottom
7877 of window: scroll_max can no longer be INT_MAX. When aggressive
7878 scrolling is in use, don't let point enter the opposite scroll
7879 margin as result of the scroll.
7880 (syms_of_xdisp) <scroll-conservatively>: Document the
7881 threshold of 100 lines for never-recentering scrolling.
7882

7892
7893 * indent.c (Fvertical_motion):
7894 * window.c (window_scroll_pixel_based, Frecenter):
7895 Don't pass `need_y_p' to `move_it_by_lines'.
7896
7897 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
7898
7899 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
7900 steal a few bits to be more compact.
7901 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
7902 Remove unneeded casts.
7903
7904 * bytecode.c (Fbyte_code): CAR and CDR can GC.
7905
7906 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
7907
7908 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
7909 binding" message (bug#7967).
7910
7911 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
7912
7913 Fix more problems found by GCC 4.6.0's static checks.
7914
7915 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
7916 Remove unused local var.
7917
7918 * editfns.c (Fmessage_box): Remove unused local var.
7919
7920 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
7921 (note_mode_line_or_margin_highlight, note_mouse_highlight):
7922 Omit unused local vars.
7923 * window.c (shrink_windows): Omit unused local var.
7924 * menu.c (digest_single_submenu): Omit unused local var.
7925 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
7926 Omit unused local var.
7927
7928 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
7929 Don't assume string length fits in int.
7930 (keyremap_step, read_key_sequence): Use size_t for sizes.
7931 (read_key_sequence): Don't check last_real_key_start redundantly.
7932
7933 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
7934 instead of alloca (Bug#8344).
7935
7936 * eval.c (Fbacktrace): Don't assume nargs fits in int.
7937 (Fbacktrace_frame): Don't assume nframes fits in int.
7938
7939 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
7940
7941 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
7942 concerns.
7943
7944 * term.c (produce_glyphless_glyph): Remove unnecessary test.
7945
7946 * cm.c (calccost): Turn while-do into do-while, for clarity.
7947
7948 * keyboard.c (syms_of_keyboard): Use the same style as later
7949 in this function when indexing through an array. This also
7950 works around GCC bug 48267.
7951
7952 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
7953
7954 * xselect.c (x_check_property_data): Return correct size (Bug#8335).

7957 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
7958
7959 * keyboard.c, keyboard.h (num_input_events): Now size_t.
7960 This avoids undefined behavior on integer overflow, and is a bit
7961 more convenient anyway since it is compared to a size_t variable.
7962
7963 Variadic C functions now count arguments with size_t, not int.
7964 This avoids an unnecessary limitation on 64-bit machines, which
7965 caused (substring ...) to crash on large vectors (Bug#8344).
7966 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
7967 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

7975 * fns.c (concat): Likewise.
7976 * frame.c (x_set_frame_parameters): Likewise.
7977 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
7978 0 if not found, not -1. All callers changed.
7979
7980 * alloc.c (garbage_collect): Don't assume stack size fits in int.
7981 (stack_copy_size): Now size_t, not int.
7982 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.

7988 All callers changed.
7989
7990 * lisp.h (multibyte_char_to_unibyte):
7991 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
7992 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
7993 * character.h (CHAR_TO_BYTE8):
7994 * cmds.c (internal_self_insert):
7995 * editfns.c (general_insert_function):
7996 * keymap.c (push_key_description):
7997 * search.c (Freplace_match):
7998 * xdisp.c (message_dolog, set_message_1): All callers changed.
7999

8001
8002 * keyboard.c (safe_run_hook_funcall): New function.
8003 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
8004 don't set the hook to nil, but remove the offending function instead.
8005 (Qcommand_hook_internal): Remove, unused.
8006 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
8007 Vcommand_hook_internal.
8008
8009 * eval.c (enum run_hooks_condition): Remove.
8010 (funcall_nil, funcall_not): New functions.
8011 (run_hook_with_args): Call each function through a `funcall' argument.

8015 (run_hook_wrapped_funcall, Frun_hook_wrapped): New functions.
8016
8017 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
8018
8019 * dispextern.h (string_buffer_position): Remove declaration.
8020
8021 * print.c (strout): Remove parameter `multibyte', unused since
8022 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
8023
8024 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
8025 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
8026 All callers changed.
8027
8028 * w32.c (_wsa_errlist): Use braces for struct initializers.
8029
8030 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
8031 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.

8070
8071 * xdisp.c (redisplay_window): Don't check buffer's clip_changed
8072 flag as a prerequisite for invoking try_scrolling. (Bug#6671)
8073
8074 2011-03-26 Juanma Barranquero <lekktu@gmail.com>
8075
8076 * w32.c (read_unc_volume): Use parameter `henum', instead of
8077 global variable `wget_enum_handle'.
8078
8079 * keymap.c (describe_vector): Remove parameters `indices' and
8080 `char_table_depth', unused since 2002-03-01T01:43:26Z!handa@m17n.org.

8175 2011-03-23 Julien Danjou <julien@danjou.info>
8176
8177 * term.c (Fsuspend_tty, Fresume_tty):
8178 * minibuf.c (read_minibuf, run_exit_minibuf_hook):

8188 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
8189 Use Frun_hooks.
8190 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
8191 unconditionally since it does the check itself.
8192
8193 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
8194
8195 Fix more problems found by GCC 4.5.2's static checks.
8196
8197 * coding.c (encode_coding_raw_text): Avoid unnecessary test
8198 the first time through the loop, since we know p0 < p1 then.
8199 This also avoids a gcc -Wstrict-overflow warning.
8200
8201 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
8202 leading to a memory leak, possible in functions like
8203 load_charset_map_from_file that can allocate an unbounded number
8204 of objects (Bug#8318).
8205
8206 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
8207 that could (at least in theory) be that large.
8208
8209 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
8210 This is less likely to overflow, and avoids undefined behavior if
8211 overflow does occur. All callers changed. Use strtoul to scan
8212 for the unsigned long integer.
8213 (pint2hrstr): Simplify and tune code slightly.
8214 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
8215

8217 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.
8218
8219 * frame.c (Fmodify_frame_parameters): Simplify loop counter.
8220 This also avoids a warning with gcc -Wstrict-overflow.

8222 This also avoids a warning with gcc -Wstrict-overflow.
8223
8224 * fileio.c (Fcopy_file): Report error if fchown or fchmod
8225 fail (Bug#8306).
8226
8227 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
8228
8229 * process.c (Fmake_network_process): Use socklen_t, not int,
8230 where POSIX says socklen_t is required in portable programs.
8231 This fixes a porting bug on hosts like 64-bit HP-UX, where
8232 socklen_t is wider than int (Bug#8277).
8233 (Fmake_network_process, server_accept_connection):
8234 (wait_reading_process_output, read_process_output):
8235 Likewise.
8236
8237 * process.c: Rename or move locals to avoid shadowing.

8244 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
8245 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
8246
8247 Make tparam.h and terminfo.c consistent.
8248 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
8249 Include tparam.h instead, since it declares them.
8250 * cm.h (PC): Remove extern decl; tparam.h now does this.
8251 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
8252 * terminfo.c: Include tparam.h, to check interfaces.
8253 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
8254 (tparam): Adjust signature to match interface in tparam.h;
8255 this removes some undefined behavior. Check that outstring and len
8256 are zero, which they always are with Emacs.
8257 * tparam.h (PC, BC, UP): New extern decls.
8258
8259 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
8260 (xftfont_open): Rename locals to avoid shadowing.
8261
8262 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
8263 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.

8267 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
8268 Rename locals to avoid shadowing.
8269
8270 * xfont.c (xfont_list_family): Mark var as initialized.
8271
8272 * xml.c (make_dom): Now static.
8273
8274 * composite.c (composition_compute_stop_pos): Rename local to
8275 avoid shadowing.
8276 (composition_reseat_it): Remove unused locals.
8277 (find_automatic_composition, composition_adjust_point): Likewise.
8278 (composition_update_it): Mark var as initialized.
8279 (find_automatic_composition): Mark vars as initialized,
8280 with a FIXME (Bug#8290).
8281
8282 character.h: Rename locals to avoid shadowing.
8283 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
8284 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
8285 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
8286 (BUF_DEC_POS): Be more systematic about renaming local temporaries
8287 to avoid shadowing.
8288
8289 * textprop.c (property_change_between_p): Remove; unused.
8290
8291 * intervals.c (interval_start_pos): Now static.
8292
8293 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
8294
8295 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
8296 Rename locals to avoid shadowing.
8297
8298 * sound.c (wav_play, au_play, Fplay_sound_internal):
8299 Fix pointer signedness.
8300 (alsa_choose_format): Remove unused local var.
8301 (wav_play): Initialize a variable to 0, to prevent undefined
8302 behavior (Bug#8278).
8303
8304 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
8305
8306 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
8307
8308 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
8309 clobbering (Bug#8298).
8310 * sysdep.c (sys_subshell): Likewise.
8311 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
8312
8313 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
8314 This should get cleaned up, so that child_setup has the

8320 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
8321
8322 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
8323 not to be necessary, and produces flickering.

8444 Move decls here, to check interfaces.
8445 * process.c (get_operating_system_release): Move decl to lisp.h.
8446 * xrdb.c (get_system_name): Likewise.
8447 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
8448 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
8449 some of which prompt warnings from gcc -Wbad-function-cast.

8479 (Fmemory_limit): Cast sbrk's returned value to char *.
8480

8486 Use functions, not macros, for up- and down-casing (Bug#8254).
8487 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
8488 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
8489 to use the following functions instead of these macros.
8490 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
8491 EMACS_INT, since callers assume the returned value fits in int.
8492 (upcase1): Likewise, for UPCASE_TABLE.
8493 (uppercasep, lowercasep, upcase): New static inline functions.
8494 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for

8500 (regex_compile, re_search_2, re_match_2_internal):
8501 Remove unused local vars.

8503 which gcc can warn about.
8504 (regex_compile, re_match_2_internal): Mark locals as initialized.
8505 (RETALLOC_IF): Define only if needed.
8506 (WORDCHAR_P): Likewise. This one is never needed, but is used
8507 only in a comment talking about a compiler bug, so put inside
8508 the #if 0 of that comment.
8509 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
8510 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
8511 Remove; unused.

8522
8523 * character.h (INC_POS, DEC_POS): Rename locals to avoid shadowing.
8524
8525 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
8526 All uses changed.
8527 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
8528 Rename locals to avoid shadowing.
8529 (Fvertical_motion): Mark locals as initialized.
8530
8531 * casefiddle.c (casify_object, casify_region): Now static.
8532 (casify_region): Mark local as initialized.
8533
8534 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
8535
8536 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
8537 New macros, so that the caller can use some names other than
8538 gcpro1, gcpro2, etc.
8539 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
8540 of the new macros.
8541 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
8542 argument, for consistency with GCPRO2_VAR, etc: it is now the
8543 prefix of the variable, not the variable itself. All uses
8544 changed.
8545 * dired.c (directory_files_internal, file_name_completion):
8546 Rename locals to avoid shadowing.
8547
8548 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
8549 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
8550 dired.c's scmp function, had undefined behavior.
8551 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
8552 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
8553 * buffer.h: ... to here, because these macros use current_buffer,
8554 and the new implementation with inline functions needs to have
8555 current_buffer in scope now, rather than later when the macros
8556 are used.
8557 (downcase, upcase1): New static inline functions.
8558 (DOWNCASE, UPCASE1): Reimplement using these functions.
8559 This avoids undefined behavior in expressions like
8560 DOWNCASE (x) == DOWNCASE (y), which previously suffered
8561 from race conditions in accessing the global variables
8562 case_temp1 and case_temp2.
8563 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
8564 * lisp.h (case_temp1, case_temp2): Remove their decls.
8565 * character.h (ASCII_CHAR_P): Move from here ...
8566 * lisp.h: ... to here, so that the inline functions mentioned
8567 above can use them.
8568
8569 * dired.c (directory_files_internal_unwind): Now static.
8570
8571 * fileio.c (file_name_as_directory, directory_file_name):
8572 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
8573 Now static.
8574 (file_name_as_directory): Use const pointers when appropriate.
8575 (Fexpand_file_name): Likewise. In particular, newdir might
8576 point at constant storage, so make it a const pointer.
8577 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
8578 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
8579 signedness issues.
8580 (Fset_file_times, Finsert_file_contents, auto_save_error):
8581 Rename locals to avoid shadowing.
8582
8583 * minibuf.c (choose_minibuf_frame_1): Now static.
8584 (Ftry_completion, Fall_completions): Rename or remove locals
8585 to avoid shadowing.
8586
8587 * marker.c (bytepos_to_charpos): Remove; unused.
8588
8589 * lisp.h (verify_bytepos, count_markers): New decls,
8590 so that gcc does not warn that these functions aren't declared.
8591
8592 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
8593 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
8594 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
8595 (copy_text): Remove unused local var.
8596
8597 * filelock.c (within_one_second): Now static.
8598 (lock_file_1): Rename local to avoid shadowing.
8599
8600 * buffer.c (fix_overlays_before): Mark locals as initialized.
8601 (fix_start_end_in_overlays): Likewise. This function should be
8602 simplified by using pointers-to-pointers, but that's a different
8603 matter.
8604 (switch_to_buffer_1): Now static.
8605 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
8606 (report_overlay_modification): Rename locals to avoid shadowing.
8607
8608 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
8609 Fix pointer signedness issue.
8610 (sys_subshell): Mark local as volatile if checking for lint,
8611 to suppress a gcc -Wclobbered warning that does not seem to be right.
8612 (MAXPATHLEN): Define only if needed.
8613
8614 * process.c (serial_open, serial_configure): Move decls from here ...
8615 * systty.h: ... to here, so that they can be checked.
8616
8617 * fns.c (get_random, seed_random): Move extern decls from here ...
8618 * lisp.h: ... to here, so that they can be checked.
8619
8620 * sysdep.c (reset_io): Now static.
8621 (wait_for_termination_signal): Remove; unused.
8622
8623 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
8624 (copy_keymap_item, append_key, push_text_char_description):
8625 Now static.
8626 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
8627 (DENSE_TABLE_SIZE): Remove; unused.
8628 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
8629 (describe_map_tree):
8630 Rename locals to avoid shadowing.
8631
8632 * keyboard.c: Declare functions static if they are not used elsewhere.
8633 (echo_char, echo_dash, cmd_error, top_level_2):
8634 (poll_for_input, handle_async_input): Now static.
8635 (read_char, kbd_buffer_get_event, make_lispy_position):
8636 (make_lispy_event, make_lispy_movement, apply_modifiers):
8637 (decode_keyboard_code, tty_read_avail_input, menu_bar_items):

8645 * alloc.c (mark_kboards): ... from here.
8646
8647 * lisp.h (force_auto_save_soon): New decl.
8648
8649 * emacs.c (init_cmdargs): Rename local to avoid shadowing.
8650 (DEFINE_DUMMY_FUNCTION): New macro.
8651 (__do_global_ctors, __do_global_ctors_aux, __do_global_dtors, __main):
8652 Use it.
8653 (main): Add casts to avoid warnings
8654 if GCC considers string literals to be constants.
8655
8656 * lisp.h (fatal_error_signal): Add decl, since it's exported.
8657
8658 * dbusbind.c: Pointer signedness fixes.
8659 (xd_signature, xd_append_arg, xd_initialize):
8660 (Fdbus_call_method, Fdbus_call_method_asynchronously):
8661 (Fdbus_method_return_internal, Fdbus_method_error_internal):
8662 (Fdbus_send_signal, xd_read_message_1, Fdbus_register_service):
8663 (Fdbus_register_signal): Use SSDATA when the context wants char *.
8664
8665 * dbusbind.c (Fdbus_init_bus): Add cast to avoid warning
8666 if GCC considers string literals to be constants.

8702 * w32inevt.c (reinvoke_input_signal, lispy_function_keys):
8703 * w32menu.c (Qmenu_bar, QCtoggle, QCradio, Qoverriding_local_map)

8720 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
8721 Assign struct members directly, instead of using BUF_BEGV etc.
