524 (clone_per_buffer_values): Don't assume that
525 sizeof (struct buffer) is a multiple of sizeof (Lisp_Object).

563 2011-07-05 Paul Eggert <eggert@cs.ucla.edu>
565 Random fixes. E.g., (random) never returned negative values.
566 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
567 subseconds part to the entropy, as that's a bit more random.
568 Prefer signed to unsigned, since the signedness doesn't matter and
569 in general we prefer signed. When given a limit, use a
570 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
571 latter isn't right if USE_2_TAGS_FOR_INTS.
572 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
573 not 0..VALMASK. Don't discard "excess" bits that random () returns.

583 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
585 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
586 This is more efficient than Ffile_directory_p and avoids a minor race.
588 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
590 * buffer.c (Foverlay_put): Say what the return value is
593 * fileio.c (barf_or_query_if_file_exists): Check first if the file
594 is a directory before asking whether to use the file name
596 (barf_or_query_if_file_exists): Make the "File is a directory"
597 error be more correct.
599 * fns.c (Frequire): Remove the mention of the .gz files, since
600 that's installation-specific, but keep the mention of
603 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
605 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

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

961 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
962 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
963 since we're not interested in debugging glyphs with old libraries.
964 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
965 GCC 4.6.0's static checking.
967 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
969 Integer overflow and signedness fixes (Bug#8873).
970 A few related buffer overrun fixes, too.
972 * font.c (font_score): Use EMACS_INT, not int, to store XINT value.
974 * dispextern.h (struct face.stipple):
975 * image.c (x_bitmap_height, x_bitmap_width, x_bitmap_pixmap)
976 (x_bitmap_mask, x_allocate_bitmap_record)
977 (x_create_bitmap_from_data, x_create_bitmap_from_file)
978 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
979 (x_create_bitmap_from_xpm_data):
980 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
981 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
983 * xfaces.c (load_pixmap):
984 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
985 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
986 (.bitmaps_last, struct x_output.icon_bitmap):
987 Use ptrdiff_t, not int, for bitmap indexes.
988 (x_allocate_bitmap_record): Check for size overflow.
989 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
991 Use ptrdiff_t, not int, for overlay counts.
992 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
993 * editfns.c (overlays_around, get_pos_property):
994 * textprop.c (get_char_property_and_overlay):
995 * xdisp.c (next_overlay_change, note_mouse_highlight):
996 * xfaces.c (face_at_buffer_position):
997 * buffer.c (OVERLAY_COUNT_MAX): New macro.
998 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
999 (Fnext_overlay_change, Fprevious_overlay_change)
1000 (mouse_face_overlay_overlaps, Foverlays_in):
1001 Use ptrdiff_t, not int, for sizes.
1002 (overlays_at, overlays_in): Check for size-calculation overflow.
1004 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
1006 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
1007 (x_session_initialize): Do not assume string length fits in int.
1009 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
1010 This is unlikely, but can occur if DPI is outlandish.
1012 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
1013 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
1015 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
1016 * xrdb.c (magic_file_p, search_magic_path):
1017 Omit last arg SUFFIX; it was always 0. All callers changed.
1018 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
1020 * xfont.c (xfont_match): Avoid need for strlen.
1022 * xfns.c: Don't assume strlen fits in int.
1023 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
1025 * xdisp.c (message_log_check_duplicate): Return intmax_t,
1026 not unsigned long, as we prefer signed integers. All callers changed.
1027 Detect integer overflow in repeat count.
1028 (message_dolog): Don't assume print length fits in 39 bytes.
1029 (display_mode_element): Don't assume strlen fits in int.
1031 * termcap.c: Don't assume sizes fit in int and never overflow.
1032 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
1033 (gobble_line): Check for size-calculation overflow.
1035 * minibuf.c (Fread_buffer):
1036 * lread.c (intern, intern_c_string):
1037 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
1038 Don't assume string length fits in int.
1040 * keyboard.c (parse_tool_bar_item):
1041 * gtkutil.c (style_changed_cb): Avoid need for strlen.
1043 * font.c: Don't assume string length fits in int.
1044 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
1045 Use ptrdiff_t, not int.
1046 (font_intern_prop): Don't assume string length fits in int.
1047 Don't assume integer property fits in fixnum.
1048 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
1050 * filelock.c: Fix some buffer overrun and integer overflow issues.
1051 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
1052 Reformulate so as not to need the command string.
1053 Invoke gzip -cd rather than gunzip, as it's more portable.
1054 (lock_info_type, lock_file_1, lock_file):
1055 Don't assume pid_t and time_t fit in unsigned long.
1056 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
1057 (current_lock_owner): Prefer signed type for sizes.
1058 Use memcpy, not strncpy, where memcpy is what is really wanted.
1059 Don't assume (via atoi) that time_t and pid_t fit in int.
1060 Check for time_t and/or pid_t out of range, e.g., via a network share.
1061 Don't alloca where an auto var works fine.
1063 * fileio.c: Fix some integer overflow issues.
1064 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
1065 Don't assume string length fits in int.
1066 (directory_file_name): Don't assume string length fits in long.
1067 (make_temp_name): Don't assume pid fits in int, or that its print
1068 length is less than 20.
1070 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
1072 * coding.c (make_subsidiaries): Don't assume string length fits in int.
1074 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
1076 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
1077 We prefer signed integers, even for size calculations.
1079 * emacs.c: Don't assume string length fits in 'int'.
1080 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
1081 (main): Don't invoke strlen when not needed.
1083 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
1084 (XD_DEBUG_MESSAGE): Don't waste a byte.
1086 * callproc.c (getenv_internal_1, getenv_internal)
1088 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
1090 * lread.c (invalid_syntax): Omit length argument.
1091 All uses changed. This doesn't fix a bug, but it simplifies the
1092 code away from its former Hollerith-constant appearance, and it's
1093 one less 'int' to worry about when looking at integer-overflow issues.
1094 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
1096 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
1097 This didn't break anything, but it didn't help either.
1098 It's confusing to put a bogus integer in a place where the actual
1099 value does not matter.
1100 (LIST_END_P): Remove unused macro and its bogus comment.
1101 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
1103 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
1104 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
1106 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
1107 We prefer signed types, and the value cannot exceed the EMACS_INT
1108 range anyway (because otherwise the length would not be representable).
1109 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
1110 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
1111 This avoids a GCC warning when WIDE_EMACS_INT.
1113 * indent.c (sane_tab_width): New function.
1114 (current_column, scan_for_column, Findent_to, position_indentation)
1115 (compute_motion): Use it. This is just for clarity.
1116 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
1118 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
1120 * lisp.h (lint_assume): New macro.
1121 * composite.c (composition_gstring_put_cache):
1122 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
1124 * editfns.c, insdel.c:
1125 Omit unnecessary forward decls, to simplify future changes.
1127 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
1129 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
1131 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
1132 Use much-faster test for byte-length change.
1133 Don't assume string byte-length fits in 'int'.
1134 Check that character arg fits in 'int'.
1135 (mapcar1): Declare byte as byte, for clarity.
1137 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
1139 * fns.c (concat): Catch string overflow earlier.
1140 Do not rely on integer wraparound.
1142 * dispextern.h (struct it.overlay_strings_charpos)
1143 (struct it.selective): Now EMACS_INT, not int.
1144 * xdisp.c (forward_to_next_line_start)
1145 (back_to_previous_visible_line_start)
1146 (reseat_at_next_visible_line_start, next_element_from_buffer):
1147 Don't arbitrarily truncate the value of 'selective' to int.
1149 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
1151 * composite.c: Don't truncate sizes to 'int'.
1152 (composition_gstring_p, composition_reseat_it)
1153 (composition_adjust_point): Use EMACS_INT, not int.
1154 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
1155 not EMACS_UINT, for indexes.
1157 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
1159 * buffer.c: Include <verify.h>.
1160 (struct sortvec.priority, struct sortstr.priority):
1161 Now EMACS_INT, not int.
1162 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
1163 (struct sortstr.size, record_overlay_string)
1164 (struct sortstrlist.size, struct sortlist.used):
1165 Don't truncate size to int.
1166 (record_overlay_string): Check for size-calculation overflow.
1167 (init_buffer_once): Check at compile-time, not run-time.
1169 2011-06-22 Jim Meyering <meyering@redhat.com>
1171 Don't leak an XBM-image-sized buffer
1172 * image.c (xbm_load): Free the image buffer after using it.
1174 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
1177 * composite.c (find_automatic_composition): Omit needless 'return 0;'
1178 that Sun C diagnosed.
1179 * fns.c (secure_hash): Fix pointer signedness issue.
1180 * intervals.c (static_offset_intervals): New function.
1181 (offset_intervals): Use it.
1183 2011-06-21 Leo Liu <sdl.web@gmail.com>
1186 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
1189 * fns.c (secure_hash): Rename from crypto_hash_function and change
1190 the first arg to accept symbols.
1191 (Fsecure_hash): New primitive.
1192 (syms_of_fns): New symbols.
1194 2011-06-20 Deniz Dogan <deniz@dogan.se>
1196 * process.c (Fset_process_buffer): Clarify return value in
1199 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
1201 * dispnew.c (add_window_display_history): Use BVAR.
1203 * xdisp.c (debug_method_add): Use BVAR.
1204 (check_window_end, dump_glyph_matrix, dump_glyph)
1205 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
1207 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
1210 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
1211 check till after the cache is created in init_frame_faces.
1213 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
1215 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
1217 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
1219 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
1220 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
1221 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
1223 Improve buffer-overflow checking (Bug#8873).
1224 * fileio.c (Finsert_file_contents):
1225 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
1226 Remove the old (too-loose) buffer overflow checks.
1227 They weren't needed, since make_gap checks for buffer overflow.
1228 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
1229 The old code merely checked for Emacs fixnum overflow, and relied
1230 on undefined (wraparound) behavior. The new code avoids undefined
1231 behavior, and also checks for ptrdiff_t and/or size_t overflow.
1233 * editfns.c (Finsert_char): Don't dump core with very negative counts.
1234 Tune. Don't use wider integers than needed. Don't use alloca.
1235 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
1237 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
1239 * insdel.c, lisp.h (buffer_overflow): New function.
1240 (insert_from_buffer_1, replace_range, replace_range_2):
1241 * insdel.c (make_gap_larger):
1242 * editfns.c (Finsert_char):
1243 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
1245 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
1247 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
1249 Integer overflow and signedness fixes (Bug#8873).
1251 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
1252 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
1254 * fileio.c: Don't assume EMACS_INT fits in off_t.
1255 (emacs_lseek): New static function.
1256 (Finsert_file_contents, Fwrite_region): Use it.
1257 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
1259 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
1261 * fns.c: Don't overflow int when computing a list length.
1262 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
1263 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
1264 truncation on 64-bit hosts. Check for QUIT every
1265 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
1266 faster and is responsive enough.
1267 (Flength): Report an error instead of overflowing an integer.
1268 (Fsafe_length): Return a float if the value is not representable
1269 as a fixnum. This shouldn't happen except in contrived situations.
1270 (Fnthcdr, Fsort): Don't assume list length fits in int.
1271 (Fcopy_sequence): Don't assume vector length fits in int.
1273 * alloc.c: Check that resized vectors' lengths fit in fixnums.
1274 (header_size, word_size): New constants.
1275 (allocate_vectorlike): Don't check size overflow here.
1276 (allocate_vector): Check it here instead, since this is the only
1277 caller of allocate_vectorlike that could cause overflow.
1278 Check that the new vector's length is representable as a fixnum.
1280 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
1281 The previous code was bogus. For example, next_almost_prime (32)
1282 returned 39, which is undesirable as it is a multiple of 3; and
1283 next_almost_prime (24) returned 25, which is a multiple of 5 so
1284 why was the code bothering to check for multiples of 7?
1286 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
1288 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
1290 Variadic C functions now count arguments with ptrdiff_t.
1291 This partly undoes my 2011-03-30 change, which replaced int with size_t.
1292 Back then I didn't know that the Emacs coding style prefers signed int.
1293 Also, in the meantime I found a few more instances where arguments
1294 were being counted with int, which may truncate counts on 64-bit
1295 machines, or EMACS_INT, which may be unnecessarily wide.
1296 * lisp.h (struct Lisp_Subr.function.aMANY)
1297 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
1298 Arg counts are now ptrdiff_t, not size_t.
1299 All variadic functions and their callers changed accordingly.
1300 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
1301 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
1302 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
1303 * callint.c (Fcall_interactively): Check arg count for overflow,
1304 to avoid potential buffer overrun. Use signed char, not 'int',
1305 for 'varies' array, so that we needn't bother to check its size
1306 calculation for overflow.
1307 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
1308 * eval.c (apply_lambda):
1309 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
1310 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
1311 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
1313 * callint.c (Fcall_interactively): Don't use index var as event count.
1315 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
1316 * mem-limits.h (SIZE): Remove; no longer used.
1318 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
1320 Remove unnecessary casts.
1321 * xterm.c (x_term_init):
1322 * xfns.c (x_set_border_pixel):
1323 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
1324 These aren't needed now that we assume ANSI C.
1326 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
1327 It's more likely to cause problems (due to unsigned overflow)
1330 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
1332 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
1334 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
1336 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
1338 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
1340 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
1342 GLYPH_CODE_FACE returns EMACS_INT, not int.
1343 * dispextern.h (merge_faces):
1344 * xfaces.c (merge_faces):
1345 * xdisp.c (get_next_display_element, next_element_from_display_vector):
1346 Don't assume EMACS_INT fits in int.
1348 * character.h (CHAR_VALID_P): Remove unused parameter.
1349 * fontset.c, lisp.h, xdisp.c: All uses changed.
1351 * editfns.c (Ftranslate_region_internal): Omit redundant test.
1353 * fns.c (concat): Minor tuning based on overflow analysis.
1354 This doesn't fix any bugs. Use int to hold character, instead
1355 of constantly refetching from Emacs object. Use XFASTINT, not
1356 XINT, for value known to be a character. Don't bother comparing
1357 a single byte to 0400, as it's always less.
1359 * floatfns.c (Fexpt):
1360 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
1362 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
1365 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
1367 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
1368 Without this fix, on a 64-bit host (aset S 0 4294967386) would
1369 incorrectly succeed when S was a string, because 4294967386 was
1370 truncated before it was used.
1372 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
1373 Otherwise, an out-of-range integer could cause undefined behavior
1376 * composite.c: Use int, not EMACS_INT, for characters.
1377 (fill_gstring_body, composition_compute_stop_pos): Use int, not
1378 EMACS_INT, for values that are known to be in character range.
1379 This doesn't fix any bugs but is the usual style inside Emacs and
1380 may generate better code on 32-bit machines.
1382 Make sure a 64-bit char is never passed to ENCODE_CHAR.
1383 This is for reasons similar to the recent CHAR_STRING fix.
1384 * charset.c (Fencode_char): Check that character arg is actually
1385 a character. Pass an int to ENCODE_CHAR.
1386 * charset.h (ENCODE_CHAR): Verify that the character argument is no
1387 wider than 'int', as a compile-time check to prevent future regressions
1390 * character.c (char_string): Remove unnecessary casts.
1392 Make sure a 64-bit char is never passed to CHAR_STRING.
1393 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
1394 by silently ignoring the top 32 bits, allowing some values
1395 that were far too large to be valid characters.
1396 * character.h: Include <verify.h>.
1397 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
1398 arguments are no wider than unsigned, as a compile-time check
1399 to prevent future regressions in this area.
1401 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
1402 (Fsubst_char_in_region):
1404 * xdisp.c (decode_mode_spec_coding):
1405 Adjust to CHAR_STRING's new requirement.
1406 * editfns.c (Finsert_char, Fsubst_char_in_region):
1407 * fns.c (concat): Check that character args are actually
1408 characters. Without this test, these functions did the wrong
1409 thing with wildly out-of-range values on 64-bit hosts.
1411 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
1412 These casts should not be needed on 32-bit hosts, either.
1413 * keyboard.c (read_char):
1414 * lread.c (Fload): Remove casts to unsigned.
1416 * lisp.h (UNSIGNED_CMP): New macro.
1417 This fixes comparison bugs on 64-bit hosts.
1418 (ASCII_CHAR_P): Use it.
1419 * casefiddle.c (casify_object):
1420 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
1421 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
1422 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
1423 * dispextern.h (FACE_FROM_ID):

1478 * alloc.c: Catch some string size overflows that we were missing.
1479 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
1480 for convenience in STRING_BYTES_MAX.
1481 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
1482 The definition here is exact; the one in lisp.h was approximate.
1483 (allocate_string_data): Check for string overflow. This catches
1484 some instances we weren't catching before. Also, it catches
1485 size_t overflow on (unusual) hosts where SIZE_MAX <= min
1486 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
1487 and ptrdiff_t and EMACS_INT are both 64 bits.
1489 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
1490 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.

2076 (bidi_level_of_next_char, bidi_move_to_visually_next): Abort if
2077 bidi_it->nchars is non-positive.
2078 (bidi_level_of_next_char): Don't try to lookup the cache for the

2096 last portion of handle_display_prop.
2097 (compute_display_string_pos): Accept additional argument
2098 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
2099 value of a `display' property is a "replacing spec".
2100 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
2101 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from

2129 All callers changed. (Bug#8762)
2131 * gnutls.c: Use Emacs's memory allocators.
2132 Without this change, the gnutls library would invoke malloc etc.
2133 directly, which causes problems on non-SYNC_INPUT hosts, and which
2134 runs afoul of improving memory_full behavior. (Bug#8761)
2135 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
2136 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
2137 xfree instead of the default malloc, realloc, free.
2138 (Fgnutls_boot): No need to check for memory allocation failure,
2139 since xmalloc does that for us.

2164 Check for overflow in vector size calculations.
2165 * ccl.c (ccl_driver):
2166 Check for overflow when converting EMACS_INT to int.
2167 * fns.c, image.c: Remove unnecessary static decls that would otherwise

2170 Check for integer overflow with large hash tables.
2171 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
2172 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
2173 (SXHASH_REDUCE): New macro.
2174 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
2175 Use it instead of discarding useful hash info with large hash values.
2176 (sxhash_float): New function.
2177 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
2178 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
2179 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
2180 Rewrite to use FIXNUM_BITS, as this simplifies things.
2181 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
2182 Adjust signatures to match updated version of code.
2183 (consing_since_gc): Now EMACS_INT, since a single hash table can
2184 use more than INT_MAX bytes.

2233 Make it possible to run ./temacs.
2235 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
2236 syms_of_callproc does the same thing. Remove test for
2237 "initialized", do it in the caller.
2238 * emacs.c (main): Avoid calling set_initial_environment when dumping.
2240 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>

2296 Avoid a sign-extension bug in crypto_hash_function.
2297 * fns.c (to_uchar): Define.
2298 (crypto_hash_function): Use it to convert some newly-signed
2299 variables to unsigned, to avoid sign-extension bugs. For example,
2300 without this change, (md5 "truc") would evaluate to
2301 45723a2aff78ff4fff7fff1114760e62 rather than the expected
2302 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
2303 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.

2318 (Fdbus_call_method, Fdbus_call_method_asynchronously):
2319 Use XFASTINT rather than XUINT when numbers are nonnegative.
2320 (xd_append_arg, Fdbus_method_return_internal):

2334 (ccl_driver): Use them to check for integer overflow when
2335 decoding a CCL program. Many of the new checks are whether XINT (x)
2336 fits in int; it doesn't always, on 64-bit hosts. The new version
2337 doesn't catch all possible integer overflows, but it's an
2338 improvement. (Bug#8719)
2340 * alloc.c (make_event_array): Use XINT, not XUINT.
2341 There's no need for unsigned here.
2343 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
2344 This follows up to the 2011-05-06 change that substituted uintptr_t
2345 for EMACS_INT. This case wasn't caught back then.
2347 Rework Fformat to avoid integer overflow issues.
2348 * editfns.c: Include <float.h> unconditionally, as it's everywhere
2349 now (part of C89). Include <verify.h>.
2350 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
2351 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
2352 (Fformat): Avoid the prepass trying to compute sizes; it was only
2353 approximate and thus did not catch overflow reliably. Instead, walk
2354 through the format just once, formatting and computing sizes as we go,
2355 checking for integer overflow at every step, and allocating a larger
2356 buffer as needed. Keep track separately whether the format is
2357 multibyte. Keep only the most-recently calculated precision, rather
2358 than them all. Record whether each argument has been converted to
2359 string. Use EMACS_INT, not int, for byte and char and arg counts.
2360 Support field widths and precisions larger than INT_MAX. Avoid
2361 sprintf's undefined behavior with conversion specifications such as %#d
2362 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
2363 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
2364 formatting out-of-range floating point numbers with int
2367 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
2369 * data.c: Avoid integer truncation in expressions involving floats.
2370 * data.c: Include <intprops.h>.
2371 (arith_driver): When there's an integer overflow in an expression
2372 involving floating point, convert the integers to floating point
2373 so that the resulting value does not suffer from catastrophic
2374 integer truncation. For example, on a 64-bit host (* 4
2375 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
2376 Do not rely on undefined behavior after integer overflow.
2378 merge count_size_as_multibyte, parse_str_to_multibyte
2379 * character.c, character.h (count_size_as_multibyte):
2380 Rename from parse_str_to_multibyte; all uses changed.
2381 Check for integer overflow.
2382 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
2383 since it's now a duplicate of the other. This is more of
2384 a character than a buffer op, so better that it's in character.c.
2385 * fns.c, print.c: Adjust to above changes.
2387 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
2389 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
2391 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
2393 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
2394 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
2395 (x_clipboard_manager_save): Now static.
2396 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
2398 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
2399 (crypto_hash_function): Now static.
2400 Fix pointer signedness problems. Avoid unnecessary initializations.
2402 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
2404 * termhooks.h (Vselection_alist): Make it terminal-local.
2406 * terminal.c (create_terminal): Initialize it.
2408 * xselect.c: Support for clipboard managers.
2409 (Vselection_alist): Move to termhooks.h as terminal-local var.
2410 (LOCAL_SELECTION): New macro.
2411 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
2412 (symbol_to_x_atom): Remove gratuitous arg.
2413 (x_handle_selection_request, lisp_data_to_selection_data)
2414 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
2415 (x_own_selection, x_get_local_selection, x_convert_selection):
2416 New arg, specifying work frame. Use terminal-local Vselection_alist.
2417 (some_frame_on_display): Delete unused function.
2418 (Fx_own_selection_internal, Fx_get_selection_internal)
2419 (Fx_disown_selection_internal, Fx_selection_owner_p)
2420 (Fx_selection_exists_p): New optional frame arg.
2421 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
2422 (x_handle_selection_clear): Don't treat other terminals with the
2423 same keyboard specially. Use the terminal-local Vselection_alist.
2424 (x_clear_frame_selections): Use Frun_hook_with_args.
2426 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
2428 * xterm.h: Add support for those atoms.
2430 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
2432 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
2433 (converted_selections, conversion_fail_tag): New global variables.
2434 (x_selection_request_lisp_error): Free the above.
2435 (x_get_local_selection): Remove unnecessary code.
2436 (x_reply_selection_request): Args changed; handle arbitrary array
2437 of converted selections stored in converted_selections.
2438 Separate the XChangeProperty and SelectionNotify steps.
2439 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
2440 (x_convert_selection): New function.
2441 (x_handle_selection_event): Simplify.
2442 (x_get_foreign_selection): Don't ignore incoming requests while
2443 waiting for an answer; this will fail when we implement
2444 SAVE_TARGETS, and seems unnecessary anyway.
2445 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
2446 (Vx_sent_selection_functions): Doc fix.
2448 2011-05-26 Leo Liu <sdl.web@gmail.com>
2450 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
2452 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2454 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
2456 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
2457 for fringe update if it has periodic bitmap.
2458 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
2459 and fringe_bitmap_periodic_p.
2461 * fringe.c (get_fringe_bitmap_data): New function.
2462 (draw_fringe_bitmap_1, update_window_fringes): Use it.
2463 (update_window_fringes): Record periodicity of fringe bitmap in glyph
2464 row. Mark glyph row for fringe update if periodicity changed.
2466 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
2467 for fringe update unless it has periodic bitmap.
2469 2011-05-25 Kenichi Handa <handa@m17n.org>
2471 * xdisp.c (get_next_display_element): Set correct it->face_id for
2472 a static composition.
2474 2011-05-24 Leo Liu <sdl.web@gmail.com>
2477 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
2479 * fns.c (crypto_hash_function, Fsha1): New function.
2480 (Fmd5): Use crypto_hash_function.
2481 (syms_of_fns): Add Ssha1.
2483 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
2485 * gnutls.c: Remove unused macros.
2486 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
2487 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
2488 Remove macros that are defined and never used.
2489 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
2491 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
2493 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
2494 (Fx_get_selection_internal): Minor cleanup.
2495 (Fx_own_selection_internal): Rename arguments for consistency with
2498 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
2500 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
2502 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
2504 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
2506 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2508 * dispnew.c (scrolling_window): Don't exclude the case that the
2509 last enabled row in the desired matrix touches the bottom boundary.
2511 2011-05-21 Glenn Morris <rgm@gnu.org>
2513 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
2514 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
2515 and add some more files.
2517 2011-05-20 Eli Zaretskii <eliz@gnu.org>
2519 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
2520 report_file_error introduced by the change from 2011-05-07.
2522 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
2524 * systime.h (Time): Define only if emacs is defined.
2525 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
2526 where the include path doesn't have X11/X.h by default. See
2527 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
2529 2011-05-20 Kenichi Handa <handa@m17n.org>
2531 * composite.c (find_automatic_composition): Fix previous change.
2533 2011-05-20 Glenn Morris <rgm@gnu.org>
2535 * lisp.mk: New file, split from Makefile.in.
2536 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
2537 (shortlisp): Remove.
2538 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
2540 2011-05-19 Glenn Morris <rgm@gnu.org>
2542 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
2543 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
2544 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
2545 (lisp): Set the order to that of loadup.el.
2546 (shortlisp): Make it a copy of $lisp.
2547 (SOME_MACHINE_LISP): Remove.
2548 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
2549 Use just $shortlisp, not $SOME_MACHINE_LISP too.
2551 2011-05-18 Kenichi Handa <handa@m17n.org>
2553 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
2554 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
2555 (find_automatic_composition): Mostly rewrite for efficiency.
2557 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
2559 * makefile.w32-in: Update dependencies.
2561 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
2563 * menu.c: Include limits.h (fixes the MS-Windows build broken by
2564 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
2566 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
2568 Fix some integer overflow issues, such as string length overflow.
2570 * insdel.c (count_size_as_multibyte): Check for string overflow.
2572 * character.c (lisp_string_width): Check for string overflow.
2573 Use EMACS_INT, not int, for string indexes and lengths; in
2574 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
2575 the resulting string length overflows an EMACS_INT; instead,
2576 report a string overflow if no precision given. When checking for
2577 precision exhaustion, use a check that cannot possibly have
2578 integer overflow. (Bug#8675)
2579 * character.h (lisp_string_width): Adjust to new signature.
2581 * alloc.c (string_overflow): New function.
2582 (Fmake_string): Use it. This doesn't change behavior, but saves
2583 a few bytes and will simplify future changes.
2584 * character.c (string_escape_byte8): Likewise.
2585 * lisp.h (string_overflow): New decl.
2587 Fixups, following up to the user-interface timestamp change.
2588 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
2589 for UI timestamps, instead of unsigned long.
2590 * msdos.c (mouse_get_pos): Likewise.
2591 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
2592 * w32gui.h (Time): Define by including "systime.h" rather than by
2593 declaring it ourselves. (Bug#8664)
2595 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
2596 * image.c (clear_image_cache): Likewise.
2598 * term.c (term_mouse_position): Don't assume time_t wraparound.
2600 Be more systematic about user-interface timestamps.
2601 Before, the code sometimes used 'Time', sometimes 'unsigned long',
2602 and sometimes 'EMACS_UINT', to represent these timestamps.
2603 This change causes it to use 'Time' uniformly, as that's what X uses.
2604 This makes the code easier to follow, and makes it easier to catch
2605 integer overflow bugs such as Bug#8664.
2606 * frame.c (Fmouse_position, Fmouse_pixel_position):
2607 Use Time, not unsigned long, for user-interface timestamps.
2608 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
2609 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
2610 * keyboard.h (last_event_timestamp): Likewise.
2611 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
2612 * menu.h (xmenu_show): Likewise.
2613 * term.c (term_mouse_position): Likewise.
2614 * termhooks.h (struct input_event.timestamp): Likewise.
2615 (struct terminal.mouse_position_hook): Likewise.
2616 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
2617 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
2618 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
2619 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
2621 * menu.h, termhooks.h: Include "systime.h", for Time.
2623 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
2624 Don't assume that the difference between two unsigned long values
2625 can fit into an integer. At this point, we know button_down_time
2626 <= event->timestamp, so the difference must be nonnegative, so
2627 there's no need to cast the result if double-click-time is
2628 nonnegative, as it should be; check that it's nonnegative, just in
2629 case. This bug is triggered when events are more than 2**31 ms
2630 apart (about 25 days). (Bug#8664)
2632 * xselect.c (last_event_timestamp): Remove duplicate decl.
2633 (x_own_selection): Remove needless cast to unsigned long.
2635 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
2636 that always fit in int. Use a sentinel instead of a counter, to
2637 avoid a temp and to allay GCC's concerns about possible int overflow.
2638 * frame.h (struct frame): Use int for menu_bar_items_used
2639 instead of EMACS_INT, since it always fits in int.
2641 * menu.c (grow_menu_items): Check for int overflow.
2643 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
2645 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
2646 Before, the code was not consistent. These values cannot exceed
2647 2**31 - 1 so there's no need to make them unsigned.
2648 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
2649 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
2650 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
2652 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
2654 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
2655 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
2656 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
2657 presumably because the widths might not match.
2659 * window.c (size_window): Avoid needless test at loop start.
2661 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
2663 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
2665 2011-05-12 Drew Adams <drew.adams@oracle.com>
2667 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
2669 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
2671 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
2672 `width' to `bar_area_x' and `bar_area_width', respectively.
2673 (x_scroll_run): Take account of fringe background extension.
2675 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
2676 Rename local vars `left' and `width' to `bar_area_x' and
2677 `bar_area_width', respectively.
2678 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
2679 background extension.
2681 2011-05-10 Jim Meyering <meyering@redhat.com>
2683 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
2685 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
2687 * image.c (Finit_image_library): Return t for built-in image types,
2688 like pbm and xbm. (Bug#8640)
2690 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
2692 * w32menu.c (set_frame_menubar): Fix submenu allocation.
2694 2011-05-07 Eli Zaretskii <eliz@gnu.org>
2696 * w32console.c (Fset_screen_color): Doc fix.
2697 (Fget_screen_color): New function.
2698 (syms_of_ntterm): Defsubr it.
2700 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
2701 unlink the temporary file if Fcall_process didn't create it in the
2703 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
2704 child process will be redirected to a file specified with `:file'.
2705 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
2706 cue to call_process_cleanup not to close that handle.
2708 2011-05-07 Ben Key <bkey76@gmail.com>
2710 * makefile.w32-in: The bootstrap-temacs rule now makes use of
2711 one of two shell specific rules, either bootstrap-temacs-CMD or
2712 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
2713 to the previous implementation of the bootstrap-temacs rule.
2714 The bootstrap-temacs-CMD rule is similar to the previous
2715 implementation of the bootstrap-temacs rule except that it
2716 makes use of the ESC_CFLAGS variable instead of the CFLAGS
2719 These changes, along with some changes to nt/configure.bat,
2720 nt/gmake.defs, and nt/nmake.defs, are required to extend my
2721 earlier fix to add support for --cflags and --ldflags options
2722 that include quotes so that it works whether make uses cmd or
2725 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
2727 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
2728 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
2730 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
2731 a string. Handle both cases.
2732 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
2733 (Fdbus_register_method): Use Qinvalid_function.
2735 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
2737 * makefile.w32-in: Update dependencies.
2738 (LISP_H): Add inttypes.h and stdin.h.
2739 (PROCESS_H): Add unistd.h.
2741 2011-05-06 Eli Zaretskii <eliz@gnu.org>
2743 * lread.c: Include limits.h (fixes the MS-Windows build broken by
2744 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
2746 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
2748 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
2750 * term.c (vfatal): Remove stray call to va_end.
2751 It's not needed and the C Standard doesn't allow it here anyway.
2753 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
2754 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
2756 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
2759 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
2761 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
2763 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
2765 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
2767 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
2769 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
2770 * charset.c (Fdefine_charset_internal): Don't initialize
2771 charset.code_space[15]. The value was garbage, on hosts with
2772 32-bit int (Bug#8600).
2774 * lread.c (read_integer): Be more consistent with string-to-number.
2775 Use string_to_number to do the actual conversion; this avoids
2776 rounding errors and fixes some other screwups. Without this fix,
2777 for example, #x1fffffffffffffff was misread as -2305843009213693952.
2778 (digit_to_number): Move earlier, for benefit of read_integer.
2779 Return -1 if the digit is out of range for the base, -2 if it is
2780 not a digit in any supported base. (Bug#8602)
2782 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
2784 * dispnew.c (scrolling_window): Return 1 if we scrolled,
2785 to match comment at start of function. This also removes a
2786 GCC warning about overflow in a 32+64-bit port.
2788 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
2790 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
2791 Reported by Stefan Monnier in
2792 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
2793 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
2794 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
2796 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
2797 (EMACS_UINTPTR): Likewise, with uintptr_t.
2799 * lisp.h: Prefer 64-bit EMACS_INT if available.
2800 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
2801 on 32-bit hosts that have 64-bit int, so that they can access
2803 However, temporarily disable this change unless the temporary
2804 symbol WIDE_EMACS_INT is defined.
2806 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
2808 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
2809 This removes an assumption that EMACS_INT and long are the same
2810 width as pointers. The assumption is true for Emacs porting targets
2811 now, but we want to make other targets possible.
2812 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
2813 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
2814 In the rest of the code, change types of integers that hold casted
2815 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
2816 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
2817 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
2818 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
2819 No need to cast type when ORing.
2820 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
2821 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
2822 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
2823 assume EMACS_INT is the same width as char *.
2824 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
2825 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
2826 Remove no-longer-needed casts.
2827 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
2828 (xg_tool_bar_help_callback, xg_make_tool_item):
2829 Use EMACS_INTPTR to hold an integer
2830 that will be cast to void *; this can avoid a GCC warning
2831 if EMACS_INT is not the same width as void *.
2832 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
2833 * xdisp.c (display_echo_area_1, resize_mini_window_1):
2834 (current_message_1, set_message_1):
2835 Use a local to convert to proper width without a cast.
2836 * xmenu.c (dialog_selection_callback): Likewise.
2838 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
2839 Also, don't assume VALBITS / RAND_BITS is less than 5,
2840 and don't rely on undefined behavior when shifting a 1 left into
2842 * lisp.h (get_random): Change signature to match.
2844 * lread.c (hash_string): Use size_t, not int, for hash computation.
2845 Normally we prefer signed values; but hashing is special, because
2846 it's better to use unsigned division on hash table sizes so that
2847 the remainder is nonnegative. Also, size_t is the natural width
2848 for hashing into memory. The previous code used 'int', which doesn't
2849 retain enough info to hash well into very large tables.
2850 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
2852 * dbusbind.c: Don't possibly lose pointer info when converting.
2853 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
2854 Use XPNTR rather than XHASH, so that the high-order bits of
2855 the pointer aren't lost when converting through void *.
2857 * eval.c (Fautoload): Don't double-shift a pointer.
2859 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
2861 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
2863 * gnutls.c (DEF_GNUTLS_FN):
2864 * image.c (DEF_IMGLIB_FN): Make function pointers static.
2866 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
2868 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
2871 2011-05-05 Eli Zaretskii <eliz@gnu.org>
2873 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
2874 New version that can reserve upto 2GB of heap space.

2880 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
2882 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
2883 `gnutls_certificate_set_x509_key_file'.
2885 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
2887 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
2888 Update dependencies.
2890 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
2892 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
2893 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
2894 Remove unused parameter `fildes'.
2895 * process.c (read_process_output, send_process): Don't pass it.
2897 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
2899 Fix previous change: the library cache is defined in w32.c.
2900 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
2901 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
2903 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
2905 Implement dynamic loading of GnuTLS on Windows.
2907 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
2908 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
2909 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
2912 * gnutls.c (Qgnutls_dll): Define.
2913 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
2914 (gnutls_*): Declare function pointers.
2915 (init_gnutls_functions): New function to initialize function pointers.

2918 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
2919 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
2920 (emacs_gnutls_write, emacs_gnutls_read)
2921 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
2922 (Fgnutls_available_p): New function.
2923 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
2924 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
2925 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
2927 * image.c: Include w32.h.
2928 (Vimage_type_cache): Delete.
2929 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
2930 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
2931 (w32_delayed_load): Move to w32.c.
2933 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
2935 * w32.c (QCloaded_from, Vlibrary_cache): Define.
2936 (w32_delayed_load): Move from image.c. When loading a library, record
2937 its filename in the :loaded-from property of the library id.
2938 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
2939 Initialize and staticpro them.
2940 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
2942 * process.c: Include lisp.h before w32.h, not after.
2943 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
2944 instead of gnutls_record_check_pending.
2946 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
2948 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
2950 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
2951 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
2954 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
2956 * xterm.c (x_set_frame_alpha): Do not set property on anything
2957 else than FRAME_X_OUTER_WINDOW (Bug#8608).
2959 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
2961 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
2963 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
2965 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
2966 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

2981 Move after wait_for_termination_1.
2983 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
2985 * sysdep.c (interruptible_wait_for_termination): New function
2986 which is like wait_for_termination, but allows keyboard
2989 * callproc.c (Fcall_process): Add (:file "file") as an option for
2991 (Fcall_process_region): Ditto.
2993 2011-04-30 Eli Zaretskii <eliz@gnu.org>
2995 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
2996 rather than `XVECTOR (FOO)->size'.
2998 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
2999 inttypes.h, as a gnulib replacement is used if it not available in
3002 2011-04-21 Eli Zaretskii <eliz@gnu.org>
3004 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
3005 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
3006 of MOST_POSITIVE_FIXNUM. (Bug#8528)
3008 * coding.c (coding_alloc_by_realloc): Error out if destination
3009 will grow beyond MOST_POSITIVE_FIXNUM.
3010 (decode_coding_emacs_mule): Abort if there isn't enough place in
3011 charbuf for the composition carryover bytes. Reserve an extra
3012 space for up to 2 characters produced in a loop.
3013 (decode_coding_iso_2022): Abort if there isn't enough place in
3014 charbuf for the composition carryover bytes.
3016 2011-04-21 Eli Zaretskii <eliz@gnu.org>
3018 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
3019 aborting when %lld or %lll format is passed.
3020 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
3021 %llo or %llx format is passed. (Bug#8545)
3023 * window.c (window_scroll_line_based): Use a marker instead of
3024 simple variables to record original value of point. (Bug#7952)
3026 * doprnt.c (doprnt): Fix the case where a multibyte sequence
3027 produced by %s or %c overflows available buffer space. (Bug#8545)
3029 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
3031 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
3032 (SIZE_MAX): Move defn after all includes, as they might #define it.
3034 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
3036 * w32.c (init_environment): Warn about defaulting HOME to C:\.
3038 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
3040 * keyboard.c (Qdelayed_warnings_hook): Define.
3041 (command_loop_1): Run `delayed-warnings-hook'
3042 if Vdelayed_warnings_list is non-nil.
3043 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
3044 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
3046 2011-04-28 Eli Zaretskii <eliz@gnu.org>
3048 * doprnt.c (doprnt): Don't return value smaller than the buffer
3049 size if the message was truncated. (Bug#8545).
3051 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
3053 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
3054 (Fx_window_property): #if-0 the whole functions, not just the bodies.
3056 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
3058 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
3060 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
3062 * makefile.w32-in: Update dependencies.
3064 2011-04-27 Eli Zaretskii <eliz@gnu.org>
3066 Improve `doprnt' and its usage. (Bug#8545)
3067 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
3068 `format_end'. Remove support for %l as a conversion specifier.
3069 Don't use xrealloc. Improve diagnostics when the %l size modifier
3070 is used. Update the commentary.
3072 * eval.c (verror): Simplify calculation of size_t.
3074 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
3077 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
3079 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
3082 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
3084 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
3085 This makes this file independent of the recent pseudovector change.
3087 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
3089 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
3091 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
3092 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
3093 Remove unused local.
3094 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
3096 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
3097 GCC 4.6.0 optimizes based on type-based alias analysis.
3098 For example, if b is of type struct buffer * and v of type struct
3099 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
3100 != &v->size, and therefore "v->size = 1; b->size = 2; return
3101 v->size;" must therefore return 1. This assumption is incorrect
3102 for Emacs, since it type-puns struct Lisp_Vector * with many other
3103 types. To fix this problem, this patch adds a new type struct
3104 vectorlike_header that documents the constraints on layout of vectors
3105 and pseudovectors, and helps optimizing compilers not get fooled
3106 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
3107 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
3108 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
3110 (XSETPVECTYPE): Rewrite in terms of new macro.
3111 (XSETPVECTYPESIZE): New macro, specifying both type and size.
3112 This is a bit clearer, and further avoids the possibility of
3113 undesirable aliasing.
3114 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
3115 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
3116 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
3117 since Lisp_Subr is a special case (no "next" field).
3118 (ASIZE): Now uses header.size rather than size.
3119 All previous uses of XVECTOR (foo)->size replaced to use this macro,
3120 to avoid the hassle of writing XVECTOR (foo)->header.size.
3121 (struct vectorlike_header): New type.
3122 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
3123 object, to help avoid aliasing.
3124 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
3125 (SUBRP): Likewise, since Lisp_Subr is a special case.
3126 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
3127 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
3128 (struct Lisp_Hash_Table): Combine first two members into a single
3129 struct vectorlike_header member. All uses of "size" and "next" members
3130 changed to be "header.size" and "header.next".
3131 * buffer.h (struct buffer): Likewise.
3132 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
3133 * frame.h (struct frame): Likewise.
3134 * process.h (struct Lisp_Process): Likewise.
3135 * termhooks.h (struct terminal): Likewise.
3136 * window.c (struct save_window_data, struct saved_window): Likewise.
3137 * window.h (struct window): Likewise.
3138 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
3139 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
3140 * buffer.c (init_buffer_once): Likewise.
3141 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
3143 * process.c (Fformat_network_address): Use local var for size,
3146 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
3148 Make the Lisp reader and string-to-float more consistent (Bug#8525)
3149 * data.c (atof): Remove decl; no longer used or needed.
3150 (digit_to_number): Move to lread.c.
3151 (Fstring_to_number): Use new string_to_number function, to be
3152 consistent with how the Lisp reader treats infinities and NaNs.
3153 Do not assume that floating-point numbers represent EMACS_INT
3154 without losing information; this is not true on most 64-bit hosts.
3155 Avoid double-rounding errors, by insisting on integers when
3156 parsing non-base-10 numbers, as the documentation specifies.
3157 * lisp.h (string_to_number): New decl, replacing ...
3158 (isfloat_string): Remove.
3159 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
3160 (read1): Do not accept +. and -. as integers; this
3161 appears to have been a coding error. Similarly, do not accept
3162 strings like +-1e0 as floating point numbers. Do not report
3163 overflow for integer overflows unless the base is not 10 which
3164 means we have no simple and reliable way to continue.
3165 Break out the floating-point parsing into a new
3166 function string_to_number, so that Fstring_to_number parses
3167 floating point numbers consistently with the Lisp reader.
3168 (digit_to_number): Move here from data.c. Make it static inline.
3169 (E_CHAR, EXP_INT): Remove, replacing with ...
3170 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
3171 (string_to_number): New function, replacing isfloat_string.
3172 This function checks for valid syntax and produces the resulting
3173 Lisp float number too. Rework it so that string-to-number
3174 no longer mishandles examples like "1.0e+". Use strtoumax,
3175 so that overflow for non-base-10 numbers is reported only when
3176 there's no portable and simple way to convert to floating point.
3178 * textprop.c (set_text_properties_1): Rewrite for clarity,
3179 and to avoid GCC warning about integer overflow.
3181 * intervals.h (struct interval): Use EMACS_INT for members
3182 where EMACS_UINT might cause problems. See
3183 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
3184 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
3185 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
3187 (offset_intervals): Tell GCC not to worry about length overflow
3188 when negating a negative length.
3190 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
3191 (overrun_check_free): Likewise.
3193 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
3194 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
3197 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
3198 (gnutls_make_error): Rename local to avoid shadowing.
3199 (gnutls_emacs_global_deinit): ifdef out; not used.
3200 (Fgnutls_boot): Use const for pointer to readonly storage.
3201 Comment out unused local. Fix pointer signedness problems.
3203 * lread.c (openp): Don't stuff size_t into an 'int'.
3204 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
3205 about possible signed overflow.
3207 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
3208 (GDK_KEY_g): Don't define if already defined.
3209 (xg_prepare_tooltip): Avoid pointer signedness problem.
3210 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
3212 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
3213 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
3215 * xfns.c (Fx_window_property): Simplify a bit,
3216 to make a bit faster and to avoid GCC 4.6.0 warning.
3217 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
3219 * fns.c (internal_equal): Don't assume size_t fits in int.
3221 * alloc.c (compact_small_strings): Tighten assertion a little.
3223 Replace pEd with more-general pI, and fix some printf arg casts.
3224 * lisp.h (pI): New macro, generalizing old pEd macro to other
3225 conversion specifiers. For example, use "...%"pI"d..." rather
3226 than "...%"pEd"...".
3227 (pEd): Remove. All uses replaced with similar uses of pI.
3228 * src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h: Likewise.
3229 * alloc.c (check_pure_size): Don't overflow by converting size to int.
3230 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
3231 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
3232 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
3233 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
3234 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
3236 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
3237 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
3238 * print.c (safe_debug_print, print_object): Likewise.
3239 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
3241 Use pI instead of if-then-else-abort. Use %p to avoid casts,
3242 avoiding the 0 flag, which is not portable.
3243 * process.c (Fmake_network_process): Use pI to avoid cast.
3244 * region-cache.c (pp_cache): Likewise.
3245 * xdisp.c (decode_mode_spec): Likewise.

3250 (x_get_window_property): Don't truncate byte count to an 'int'
3253 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
3254 here, since it parses constructs like leading '-' and spaces,
3255 which are not wanted; and it overflows with large numbers.
3256 Instead, simply match F[0-9]+, which is what is wanted anyway.
3258 * alloc.c: Remove unportable assumptions about struct layout.
3259 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
3260 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
3261 (allocate_vectorlike, make_pure_vector): Use the new macros,
3262 plus offsetof, to remove unportable assumptions about struct layout.
3263 These assumptions hold on all porting targets that I know of, but
3264 they are not guaranteed, they're easy to remove, and removing them
3265 makes further changes easier.
3267 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
3268 This doesn't fix a bug but makes the code clearer.
3269 (string_overrun_cookie): Now const. Use initializers that
3270 don't formally overflow signed char, to avoid warnings.
3271 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
3272 can cause Emacs to crash when string overrun checking is enabled.
3273 (allocate_buffer): Don't assume sizeof (struct buffer) is a
3274 multiple of sizeof (EMACS_INT); it need not be, if
3275 alignof(EMACS_INT) < sizeof (EMACS_INT).
3276 (check_sblock, check_string_bytes, check_string_free_list): Protoize.

3312 supported by the function. Use SAFE_ALLOCA instead of always
3315 * eval.c (verror): Don't limit the buffer size at size_max-1, that
3316 is one byte too soon. Don't use xrealloc; instead xfree and

3429 about invalid control letter, pass the character's codepoint, not
3430 a pointer to its multibyte form. Improve display of the character
3431 in octal and display also its hex code.
3433 * character.c (char_string): Use %x to display the (unsigned)
3434 codepoint of an invalid character, to avoid displaying a bogus
3437 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
3438 `error', not SYMBOL_NAME itself.
3440 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
3441 character arguments to `error'.
3443 * charset.c (check_iso_charset_parameter): Fix incorrect argument
3444 to `error' in error message about FINAL_CHAR argument. Make sure
3445 FINAL_CHAR is a character, and use %c when it is passed as
3446 argument to `error'.

3510 Define only if needed.
3512 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier

3636 ns_descriptor_to_entity that were caused by using free to
3637 deallocate memory blocks that were allocated by xmalloc (via
3638 xstrdup). This caused Emacs to crash when compiled with
3639 XMALLOC_OVERRUN_CHECK defined (when Emacs was configured with
3640 --enable-checking=xmallocoverrun). xfree is now used to
3641 deallocate these memory blocks.

3657 * sysdep.c (MAX_RW_COUNT): New macro, to work around kernel bugs.
3658 (emacs_read, emacs_write): Use it.
3659 * process.c (send_process): Adjust to the new signatures of
3660 emacs_write and emacs_gnutls_write. Do not attempt to store
3661 a byte offset into an 'int'; it might overflow.
3662 See http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00483.html

4148 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
4149 argument, local variables, and return value.
4151 * lisp.h: Update prototypes of emacs_write and emacs_read.
4153 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
4155 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
4157 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
4159 Fix more problems found by GCC 4.6.0's static checks.
4161 * xdisp.c (vmessage): Use a better test for character truncation.
4163 * charset.c (load_charset_map): <, not <=, for optimization,
4164 and to avoid potential problems with integer overflow.
4165 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
4166 * casetab.c (set_identity, shuffle): Likewise.
4167 * editfns.c (Fformat): Likewise.
4168 * syntax.c (skip_chars): Likewise.
4170 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
4171 This also lets GCC 4.6.0 generate slightly better loop code.
4173 * callint.c (Fcall_interactively): <, not <=, for optimization.
4174 (Fcall_interactively): Count the number of arguments produced,
4175 not the number of arguments given. This is simpler and lets GCC
4176 4.6.0 generate slightly better code.
4178 * ftfont.c: Distingish more carefully between FcChar8 and char.
4179 The previous code passed unsigned char * to a functions like
4180 strlen and xstrcasecmp that expect char *, which does not
4181 conform to the C standard.
4182 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
4183 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
4184 char * when the C standard requires it.
4186 * keyboard.c (read_char): Remove unused var.
4188 * eval.c: Port to Windows vsnprintf (Bug#8435).
4190 (SIZE_MAX): Define if the headers do not.
4191 (verror): Do not give up if vsnprintf returns a negative count.
4192 Instead, grow the buffer. This ports to Windows vsnprintf, which
4193 does not conform to C99. Problem reported by Eli Zaretskii.
4194 Also, simplify the allocation scheme, by avoiding the need for
4195 calling realloc, and removing the ALLOCATED variable.
4197 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
4199 Remove invocations of doprnt, as Emacs now uses vsnprintf.
4200 But keep the doprint source code for now, as we might revamp it
4201 and use it again (Bug#8435).
4202 * lisp.h (doprnt): Remove.
4203 * Makefile.in (base_obj): Remove doprnt.o.
4204 * deps.mk (doprnt.o): Remove.
4206 error: Print 32- and 64-bit integers portably (Bug#8435).
4207 Without this change, on typical 64-bit hosts error ("...%d...", N)
4208 was used to print both 32- and 64-bit integers N, which relied on
4210 * lisp.h, src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h (pEd):
4212 * lisp.h (error, verror): Mark as printf-like functions.
4213 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
4214 Report overflow in size calculations when allocating printf buffer.
4215 Do not truncate output string at its first null byte.
4216 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
4217 Truncate the output at a character boundary, since vsnprintf does not
4219 * charset.c (check_iso_charset_parameter): Convert internal
4220 character to string before calling 'error', since %c now has the
4222 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
4223 overflow when computing char to be passed to 'error'. Do not
4224 pass Lisp_Object to 'error'; pass the integer instead.
4225 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
4226 formatted with plain %d.
4228 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
4230 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
4232 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
4234 * xterm.c (x_catch_errors): Remove duplicate declaration.
4236 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
4238 * xdisp.c, lisp.h (message_nolog): Remove; unused.
4240 2011-04-10 Jim Meyering <meyering@redhat.com>
4242 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
4243 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
4244 return ssize_t not "int", and use size_t as the buffer length.
4245 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
4246 * gnutls.h: Update declarations.
4247 * process.c (read_process_output): Use ssize_t, to match.
4248 (send_process): Likewise.
4250 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
4252 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
4254 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
4256 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
4257 Use unsigned char, to match FcChar8 type definition.
4259 * xterm.c (handle_one_xevent):
4260 * xmenu.c (create_and_show_popup_menu):
4261 * xselect.c (x_decline_selection_request)
4262 (x_reply_selection_request): Avoid type-punned deref of X events.
4264 2011-04-09 Eli Zaretskii <eliz@gnu.org>
4266 Fix some uses of `int' instead of EMACS_INT.
4267 * search.c (string_match_1, fast_string_match)
4268 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
4269 (scan_buffer, find_next_newline_no_quit)
4270 (find_before_next_newline, search_command, Freplace_match)
4271 (Fmatch_data): Make some `int' variables be EMACS_INT.
4273 * xdisp.c (display_count_lines): 3rd argument and return value now
4274 EMACS_INT. All callers changed.
4275 (pint2hrstr): Last argument is now EMACS_INT.
4277 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
4278 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
4279 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
4280 (decode_coding_utf_16, decode_coding_emacs_mule)
4281 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
4282 (decode_coding_ccl, decode_coding_charset)
4283 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
4284 (decode_coding_iso_2022, decode_coding_emacs_mule)
4285 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
4286 <char_offset, last_offset>: Declare EMACS_INT.
4287 (encode_coding_utf_8, encode_coding_utf_16)
4288 (encode_coding_emacs_mule, encode_invocation_designation)
4289 (encode_designation_at_bol, encode_coding_iso_2022)
4290 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
4291 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
4293 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
4294 (encode_invocation_designation): Last argument P_NCHARS is now
4296 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
4297 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
4299 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
4302 * ccl.c (Fccl_execute_on_string): Declare some variables
4305 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
4307 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).

4313 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
4315 * xml.c (parse_region): Avoid creating spurious whiespace nodes.
4317 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
4319 * keyboard.c (read_char): Call Lisp function help-form-show,
4320 instead of using internal_with_output_to_temp_buffer.
4321 (Qhelp_form_show): New var.
4322 (syms_of_keyboard): Use DEFSYM macro.
4324 * print.c (internal_with_output_to_temp_buffer): Function deleted.
4326 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
4328 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
4330 * process.c (Flist_processes): Remove to Lisp.
4331 (list_processes_1): Delete.
4333 2011-04-06 Eli Zaretskii <eliz@gnu.org>
4335 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
4337 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
4339 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
4341 Fix more problems found by GCC 4.6.0's static checks.
4343 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
4345 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
4347 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
4349 * xdisp.c (vmessage): Mark as a printf-like function.
4351 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
4353 * sound.c (sound_warning): Don't crash if arg contains a printf format.
4355 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
4356 printf-like functions.
4357 (tiff_load): Add casts to remove these marks before passing them
4358 to system-supplied API.
4360 * eval.c (Fsignal): Remove excess argument to 'fatal'.
4362 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
4363 This avoids several warnings with gcc -Wstrict-overflow.
4364 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
4365 directly, rather than having caller test rule sign. This avoids
4366 some unnecessary tests.
4367 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
4368 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
4369 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
4371 * xfont.c (xfont_text_extents): Remove var that was set but not used.
4372 (xfont_open): Avoid unnecessary tests.
4374 * composite.c (composition_gstring_put_cache): Use unsigned integer.
4376 * composite.h, composite.c (composition_gstring_put_cache):
4377 Use EMACS_INT, not int, for length.
4379 * composite.h (COMPOSITION_DECODE_REFS): New macro,
4380 breaking out part of COMPOSITION_DECODE_RULE.

4383 by using the new macro.
4385 * textprop.c (set_text_properties_1): Change while to do-while,
4386 since the condition is always true at first.
4388 * intervals.c (graft_intervals_into_buffer): Mark var as used.
4389 (interval_deletion_adjustment): Return unsigned value.
4392 * process.c (list_processes_1, create_pty, read_process_output):

4399 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
4401 * syntax.c (scan_words): Remove var that was set but not used.
4402 (update_syntax_table): Use unsigned instead of int.
4404 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.

4408 * print.c (print_error_message): Avoid int overflow.
4410 * font.c (font_list_entities): Redo for clarity,
4411 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
4413 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
4414 (font_score): Avoid potential overflow in diff calculation.
4416 * fns.c (substring_both): Remove var that is set but not used.
4417 (sxhash): Redo loop for clarity and to avoid wraparound warning.
4419 * eval.c (funcall_lambda): Rename local to avoid shadowing.
4421 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
4422 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
4423 can always succeed if overflow has undefined behavior.
4425 * search.c (boyer_moore, wordify): Remove vars set but not used.
4426 (wordify): Omit three unnecessary tests.
4428 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
4429 All callers changed. This avoids the need for an unused var.
4431 * casefiddle.c (casify_region): Remove var that is set but not used.
4433 * dired.c (file_name_completion): Remove var that is set but not used.
4435 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
4437 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
4438 (Finsert_file_contents): Remove unnecessary code checking fd.
4440 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
4441 Check for integer overflow on size calculations.
4443 * buffer.c (Fprevious_overlay_change): Remove var that is set
4446 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
4447 Remove vars that are set but not used.
4448 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
4449 (timer_check_2): Mark vars as initialized.
4451 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
4453 * image.c (lookup_image): Remove var that is set but not used.
4454 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
4456 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
4457 that are set but not used.
4459 * xfns.c (make_invisible_cursor): Don't return garbage
4460 if XCreateBitmapFromData fails (Bug#8410).
4462 * xselect.c (x_get_local_selection, x_handle_property_notify):
4463 Remove vars that are set but not used.
4465 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
4466 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
4468 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
4469 Remove var that is set but not used.
4470 (scroll_bar_windows_size): Now size_t, not int.
4471 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
4474 * xfaces.c (realize_named_face): Remove vars that are set but not used.
4475 (map_tty_color) [!defined MSDOS]: Likewise.
4477 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
4479 * coding.c: Remove vars that are set but not used.
4480 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
4481 All callers changed.
4482 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
4483 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
4484 (decode_coding_charset): Remove vars that are set but not used.
4486 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
4487 that is set but not used.
4489 * print.c (print_object): Remove var that is set but not used.
4491 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
4492 The gnulib version avoids calling malloc in the usual case,
4493 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
4494 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
4495 * filelock.c (current_lock_owner): Likewise.
4496 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
4497 * sysdep.c: Include allocator.h, careadlinkat.h.
4498 (emacs_no_realloc_allocator): New static constant.
4499 (emacs_readlink): New function.
4500 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
4501 ../lib/careadlinkat.h.
4503 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
4505 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
4506 first non-nil return value).
4508 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
4510 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
4511 if not defined (Bug#8403).
4513 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
4515 * xdisp.c (display_count_lines): Remove parameter `start',
4516 unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
4517 (get_char_face_and_encoding): Remove parameter `multibyte_p',
4518 unused since 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
4519 (fill_stretch_glyph_string): Remove parameters `row' and `area',
4520 unused at least since Kim's GUI unification at 2003-03-16T20:45:46Z!storm@cua.dk
4521 and thereabouts. All callers changed.
4522 (get_per_char_metric): Remove parameter `f', unused since
4523 2008-05-14T01:40:23Z!handa@m17n.org. All callers changed.
4525 2011-04-02 Jim Meyering <meyering@redhat.com>
4527 do not dereference NULL upon failed strdup
4528 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
4529 (ns_get_family): Likewise.
4531 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
4533 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
4535 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
4537 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
4540 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
4542 Add lexical binding.
4544 * window.c (Ftemp_output_buffer_show): New fun.
4545 (Fsave_window_excursion):

4549 (Fload): Bind Qlexical_binding.
4550 (readevalloop): Remove `evalfun' arg.
4551 Bind Qinternal_interpreter_environment.
4552 (Feval_buffer): Bind Qlexical_binding.
4553 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
4555 (syms_of_lread): Declare `lexical-binding'.
4557 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
4559 * keyboard.c (eval_dyn): New fun.
4560 (menu_item_eval_property): Use it.
4562 * image.c (parse_image_spec): Use Ffunctionp.
4564 * fns.c (concat, mapcar1): Accept byte-code-functions.
4566 * eval.c (Fsetq): Handle lexical vars.
4567 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
4568 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
4569 (FletX, Flet): Obey lexical binding.
4570 (Fcommandp): Handle closures.
4571 (Feval): New `lexical' arg.
4572 (eval_sub): New function extracted from Feval. Use it almost
4573 everywhere where Feval was used. Look up vars in lexical env.
4575 (Ffunctionp): Move from subr.el.
4576 (Ffuncall): Handle closures.
4577 (apply_lambda): Remove `eval_flags'.
4578 (funcall_lambda): Handle closures and new byte-code-functions.
4579 (Fspecial_variable_p): New function.
4580 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
4581 but without exporting it to Lisp.
4583 * doc.c (Fdocumentation, store_function_docstring):
4584 * data.c (Finteractive_form): Handle closures.
4586 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
4589 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
4591 (exec_byte_code): New function extracted from Fbyte_code to handle new
4592 calling convention for byte-code-functions. Add new byte-codes.
4594 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
4596 * alloc.c (Fmake_symbol): Init new `declared_special' field.
4598 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
4600 * xdisp.c (redisplay_internal): Fix prototype.
4602 2011-03-31 Eli Zaretskii <eliz@gnu.org>
4604 * xdisp.c (SCROLL_LIMIT): New macro.
4605 (try_scrolling): Use it when setting scroll_limit.
4606 Limit scrolling to 100 screen lines.
4607 (redisplay_window): Even when falling back on "recentering",
4608 position point in the window according to scroll-conservatively,
4609 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
4611 (try_scrolling): When point is above the window, allow searching
4612 as far as scroll_max, or one screenful, to compute vertical
4613 distance from PT to the scroll margin position. This prevents
4614 try_scrolling from unnecessarily failing when
4615 scroll-conservatively is set to a value slightly larger than the
4616 window height. Clean up the case of PT below the margin at bottom
4617 of window: scroll_max can no longer be INT_MAX. When aggressive
4618 scrolling is in use, don't let point enter the opposite scroll
4619 margin as result of the scroll.
4620 (syms_of_xdisp) <scroll-conservatively>: Document the
4621 threshold of 100 lines for never-recentering scrolling.
4623 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
4625 * dispextern.h (move_it_by_lines):

4627 since 2000-12-29T14:24:09Z!gerd@gnu.org. All callers changed.
4628 (message_log_check_duplicate): Remove parameters `prev_bol' and
4629 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
4630 (redisplay_internal): Remove parameter `preserve_echo_area',
4631 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
4633 * indent.c (Fvertical_motion):
4634 * window.c (window_scroll_pixel_based, Frecenter):
4635 Don't pass `need_y_p' to `move_it_by_lines'.
4637 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
4639 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
4640 steal a few bits to be more compact.
4641 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
4642 Remove unneeded casts.
4644 * bytecode.c (Fbyte_code): CAR and CDR can GC.
4646 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
4648 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
4649 binding" message (bug#7967).
4651 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
4653 Fix more problems found by GCC 4.6.0's static checks.
4655 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
4656 Remove unused local var.
4658 * editfns.c (Fmessage_box): Remove unused local var.
4660 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
4661 (note_mode_line_or_margin_highlight, note_mouse_highlight):
4662 Omit unused local vars.
4663 * window.c (shrink_windows): Omit unused local var.
4664 * menu.c (digest_single_submenu): Omit unused local var.
4665 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
4666 Omit unused local var.
4668 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
4669 Don't assume string length fits in int.
4670 (keyremap_step, read_key_sequence): Use size_t for sizes.
4671 (read_key_sequence): Don't check last_real_key_start redundantly.
4673 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
4674 instead of alloca (Bug#8344).
4676 * eval.c (Fbacktrace): Don't assume nargs fits in int.
4677 (Fbacktrace_frame): Don't assume nframes fits in int.
4679 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

4684 * term.c (produce_glyphless_glyph): Remove unnecessary test.
4686 * cm.c (calccost): Turn while-do into do-while, for clarity.
4688 * keyboard.c (syms_of_keyboard): Use the same style as later
4689 in this function when indexing through an array. This also
4690 works around GCC bug 48267.
4692 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
4694 * xselect.c (x_check_property_data): Return correct size (Bug#8335).

4697 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
4699 * keyboard.c, keyboard.h (num_input_events): Now size_t.
4700 This avoids undefined behavior on integer overflow, and is a bit
4701 more convenient anyway since it is compared to a size_t variable.
4703 Variadic C functions now count arguments with size_t, not int.
4704 This avoids an unnecessary limitation on 64-bit machines, which
4705 caused (substring ...) to crash on large vectors (Bug#8344).
4706 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
4707 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.
4708 All variadic functions and their callers changed accordingly.

4714 (funcall_lambda, mark_backtrace): Likewise.
4715 * fns.c (concat): Likewise.
4716 * frame.c (x_set_frame_parameters): Likewise.
4717 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
4718 0 if not found, not -1. All callers changed.
4720 * alloc.c (garbage_collect): Don't assume stack size fits in int.
4721 (stack_copy_size): Now size_t, not int.
4722 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
4724 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
4726 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',

4728 All callers changed.
4730 * lisp.h (multibyte_char_to_unibyte):
4731 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
4732 unused since 2002-03-01T01:16:34Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.
4733 * character.h (CHAR_TO_BYTE8):
4734 * cmds.c (internal_self_insert):
4735 * editfns.c (general_insert_function):
4736 * keymap.c (push_key_description):
4737 * search.c (Freplace_match):
4738 * xdisp.c (message_dolog, set_message_1): All callers changed.
4740 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
4742 * keyboard.c (safe_run_hook_funcall): New function.
4743 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
4744 don't set the hook to nil, but remove the offending function instead.
4745 (Qcommand_hook_internal): Remove, unused.
4746 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
4747 Vcommand_hook_internal.
4749 * eval.c (enum run_hooks_condition): Remove.
4750 (funcall_nil, funcall_not): New functions.
4751 (run_hook_with_args): Call each function through a `funcall' argument.
4752 Remove `cond' argument, now redundant.

4761 * print.c (strout): Remove parameter `multibyte', unused since
4762 1999-08-21T19:30:21Z!gerd@gnu.org. All callers changed.
4764 * search.c (boyer_moore): Remove parameters `len', `pos' and `lim',
4765 never used since function introduction in 1998-02-08T21:33:56Z!rms@gnu.org.
4766 All callers changed.
4768 * w32.c (_wsa_errlist): Use braces for struct initializers.
4770 * xdisp.c (string_buffer_position_lim): Remove parameter `w',
4771 never used since function introduction in 2001-03-09T18:41:50Z!gerd@gnu.org.
4772 All callers changed.
4773 (string_buffer_position): Likewise. Also, make static (it's never
4774 used outside xdisp.c).
4775 (cursor_row_p): Remove parameter `w', unused since
4776 2000-10-17T16:08:57Z!gerd@gnu.org. All callers changed.
4777 (decode_mode_spec): Remove parameter `precision', introduced during
4778 Gerd Moellmann's rewrite at 1999-07-21T21:43:52Z!gerd@gnu.org, but never used.
4779 All callers changed.

4918 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
4919 * window.c (temp_output_buffer_show):
4920 * insdel.c (signal_before_change):
4921 * frame.c (Fhandle_switch_frame):
4922 * fileio.c (Fdo_auto_save):

4924 * editfns.c (save_excursion_restore):
4925 * cmds.c (internal_self_insert):
4926 * callint.c (Fcall_interactively):
4927 * buffer.c (Fkill_all_local_variables):
4928 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
4930 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
4931 unconditionnaly since it does the check itself.
4933 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
4935 Fix more problems found by GCC 4.5.2's static checks.
4937 * coding.c (encode_coding_raw_text): Avoid unnecessary test
4938 the first time through the loop, since we know p0 < p1 then.
4939 This also avoids a gcc -Wstrict-overflow warning.
4941 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
4942 leading to a memory leak, possible in functions like
4943 load_charset_map_from_file that can allocate an unbounded number
4944 of objects (Bug#8318).
4946 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
4947 that could (at least in theory) be that large.
4949 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
4950 This is less likely to overflow, and avoids undefined behavior if
4951 overflow does occur. All callers changed. Use strtoul to scan
4952 for the unsigned long integer.
4953 (pint2hrstr): Simplify and tune code slightly.
4954 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

4962 This also avoids a warning with gcc -Wstrict-overflow.
4964 * fileio.c (Fcopy_file): Report error if fchown or fchmod
4967 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
4969 * process.c (Fmake_network_process): Use socklen_t, not int,
4970 where POSIX says socklen_t is required in portable programs.
4971 This fixes a porting bug on hosts like 64-bit HP-UX, where
4972 socklen_t is wider than int (Bug#8277).
4973 (Fmake_network_process, server_accept_connection):
4974 (wait_reading_process_output, read_process_output):
4977 * process.c: Rename or move locals to avoid shadowing.

4987 Make tparam.h and terminfo.c consistent.
4988 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
4989 Include tparam.h instead, since it declares them.
4990 * cm.h (PC): Remove extern decl; tparam.h now does this.
4991 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
4992 * terminfo.c: Include tparam.h, to check interfaces.
4993 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
4994 (tparam): Adjust signature to match interface in tparam.h;
4995 this removes some undefined behavior. Check that outstring and len
4996 are zero, which they always are with Emacs.
4997 * tparam.h (PC, BC, UP): New extern decls.
4999 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
5000 (xftfont_open): Rename locals to avoid shadowing.
5002 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
5003 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
5004 (OTF_TAG_SYM): Omit macro if not needed.
5005 (ftfont_list): Remove unused local.
5006 (get_adstyle_property, ftfont_pattern_entity):
5007 (ftfont_lookup_cache, ftfont_open, ftfont_anchor_point):
5008 Rename locals to avoid shadowing.
5010 * xfont.c (xfont_list_family): Mark var as initialized.
5012 * xml.c (make_dom): Now static.
5014 * composite.c (composition_compute_stop_pos): Rename local to

5017 (find_automatic_composition, composition_adjust_point): Likewise.
5018 (composition_update_it): Mark var as initialized.
5019 (find_automatic_composition): Mark vars as initialized,
5020 with a FIXME (Bug#8290).
5022 character.h: Rename locals to avoid shadowing.
5023 * character.h (PREV_CHAR_BOUNDARY, FETCH_STRING_CHAR_ADVANCE):
5024 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
5025 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
5026 (BUF_DEC_POS): Be more systematic about renaming local temporaries
5029 * textprop.c (property_change_between_p): Remove; unused.
5031 * intervals.c (interval_start_pos): Now static.
5033 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".
5035 * atimer.c (start_atimer, append_atimer_lists, set_alarm):
5036 Rename locals to avoid shadowing.
5038 * sound.c (wav_play, au_play, Fplay_sound_internal):
5039 Fix pointer signedness.
5040 (alsa_choose_format): Remove unused local var.
5041 (wav_play): Initialize a variable to 0, to prevent undefined
5042 behavior (Bug#8278).
5044 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
5046 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
5048 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
5049 clobbering (Bug#8298).
5050 * sysdep.c (sys_subshell): Likewise.
5051 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
5053 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
5054 This should get cleaned up, so that child_setup has the
5055 same signature on all platforms.
5057 * callproc.c (call_process_cleanup): Now static.
5058 (relocate_fd): Rename locals to avoid shadowing.
5060 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
5062 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
5063 not to be necessary, and produces flickering.
5065 2011-03-20 Glenn Morris <rgm@gnu.org>
5067 * config.in: Remove file.
5069 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
5071 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
5072 are now in src/globals.h.
5073 (syms_of_minibuf): Remove spurious & from previous change.
5075 2011-03-20 Leo <sdl.web@gmail.com>

5227 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
5228 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
5229 to use the following functions instead of these macros.
5230 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
5231 EMACS_INT, since callers assume the returned value fits in int.
5232 (upcase1): Likewise, for UPCASE_TABLE.

5244 (regex_compile, re_match_2_internal): Mark locals as initialized.
5245 (RETALLOC_IF): Define only if needed.
5246 (WORDCHAR_P): Likewise. This one is never needed, but is used
5247 only in a comment talking about a compiler bug, so put inside
5248 the #if 0 of that comment.
5249 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
5250 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
5253 * search.c (boyer_moore): Rename locals to avoid shadowing.

5276 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
5277 New macros, so that the caller can use some names other than
5278 gcpro1, gcpro2, etc.
5279 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
5281 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
5282 argument, for consistency with GCPRO2_VAR, etc: it is now the
5283 prefix of the variable, not the variable itself. All uses
5285 * dired.c (directory_files_internal, file_name_completion):
5286 Rename locals to avoid shadowing.
5288 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
5289 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
5290 dired.c's scmp function, had undefined behavior.
5291 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
5292 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
5293 * buffer.h: ... to here, because these macros use current_buffer,
5294 and the new implementation with inline functions needs to have
5295 current_buffer in scope now, rather than later when the macros
5297 (downcase, upcase1): New static inline functions.
5298 (DOWNCASE, UPCASE1): Reimplement using these functions.
5299 This avoids undefined behavior in expressions like
5300 DOWNCASE (x) == DOWNCASE (y), which previously suffered
5301 from race conditions in accessing the global variables
5302 case_temp1 and case_temp2.
5303 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
5304 * lisp.h (case_temp1, case_temp2): Remove their decls.
5305 * character.h (ASCII_CHAR_P): Move from here ...
5306 * lisp.h: ... to here, so that the inline functions mentioned
5309 * dired.c (directory_files_internal_unwind): Now static.
5311 * fileio.c (file_name_as_directory, directory_file_name):
5312 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
5314 (file_name_as_directory): Use const pointers when appropriate.
5315 (Fexpand_file_name): Likewise. In particular, newdir might
5316 point at constant storage, so make it a const pointer.
5317 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
5318 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
5320 (Fset_file_times, Finsert_file_contents, auto_save_error):
5321 Rename locals to avoid shadowing.

5327 * marker.c (bytepos_to_charpos): Remove; unused.
5329 * lisp.h (verify_bytepos, count_markers): New decls,
5330 so that gcc does not warn that these functions aren't declared.
5332 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
5333 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.

5335 (copy_text): Remove unused local var.
5337 * filelock.c (within_one_second): Now static.
5338 (lock_file_1): Rename local to avoid shadowing.
5340 * buffer.c (fix_overlays_before): Mark locals as initialized.
5341 (fix_start_end_in_overlays): Likewise. This function should be
5342 simplified by using pointers-to-pointers, but that's a different
5344 (switch_to_buffer_1): Now static.
5345 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
5346 (report_overlay_modification): Rename locals to avoid shadowing.
5348 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
5349 Fix pointer signedness issue.
5350 (sys_subshell): Mark local as volatile if checking for lint,
5351 to suppress a gcc -Wclobbered warning that does not seem to be right.
5352 (MAXPATHLEN): Define only if needed.
5354 * process.c (serial_open, serial_configure): Move decls from here ...
5355 * systty.h: ... to here, so that they can be checked.
5357 * fns.c (get_random, seed_random): Move extern decls from here ...
5358 * lisp.h: ... to here, so that they can be checked.
5360 * sysdep.c (reset_io): Now static.
5361 (wait_for_termination_signal): Remove; unused.
5363 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
5364 (copy_keymap_item, append_key, push_text_char_description):
5366 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.

5370 Rename locals to avoid shadowing.
5372 * keyboard.c: Declare functions static if they are not used elsewhere.
5373 (echo_char, echo_dash, cmd_error, top_level_2):
5374 (poll_for_input, handle_async_input): Now static.
5375 (read_char, kbd_buffer_get_event, make_lispy_position):

5394 if GCC considers string literals to be constants.
5396 * lisp.h (fatal_error_signal): Add decl, since it's exported.

5520 1152921504606846976) returns the obviously-bogus value (-948597
5521 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
5522 reports time overflow. See
5523 <http://lists.gnu.org/archive/html/emacs-devel/2011-03/msg00470.html>.
