561 * w32.c (init_environment): Change the default values of many
562 environment variables in dflt_envvars[] to NULL, to avoid pushing
563 them into environment when they were not already defined.
564 Remove the code that deletes site-lisp subdirectories from the default
565 value of EMACSLOADPATH, as it is no longer needed.
566 (check_windows_init_file): Now external, not static.
567 Use Vload_path as is, without adding anything, as this function is now
568 called when Vload_path is already set up.
570 * w32.h (check_windows_init_file): Add prototype.
572 * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build

579 installation tree, as appropriate.
581 * callproc.c (init_callproc_1): Call decode_env_path instead of
582 doing its equivalent by hand.

615 * xterm.c (x_set_frame_alpha, x_find_modifier_meanings):
616 Remove unnecessary pointer casts.
617 * alloc.c (record_xmalloc): New function.
618 * lisp.h (record_xmalloc): New decl.
619 (SAFE_ALLOCA): Now takes just one arg -- the size -- and acts
620 more like a function. This is because the pointer cast is not
621 needed. All uses changed.
622 * print.c (print_string, print_error_message): Avoid length recalc.
624 Improve fix for macroexp crash with debugging (Bug#12118).
625 * lisp.h (ASET) [ENABLE_CHECKING]: Pay attention to
626 ARRAY_MARK_FLAG when checking subscripts, because ASET is
627 not supposed to be invoked from the garbage collector.
628 See Andreas Schwab in <http://bugs.gnu.org/12118#25>.
629 (gc_aset): New function, which is like ASET but can be
630 used in the garbage collector.

646 headers (most versions of MinGW w32api don't).
647 (get_security_info, create_symbolic_link)
648 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
649 New functions.
650 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks

659 with addition of handling of symlinks and support for 'lstat'.
660 If possible, get file's attributes and security information by
661 handle, not by name. Produce S_IFLNK bit for symlinks, when
662 called from 'lstat'.
663 (stat, lstat): New functions, call 'stat_worker'.
664 (symlink, readlink, careadlinkat): Rewritten to create and resolve
665 symlinks when the underlying filesystem supports them.

669 Fix macroexp crash on Windows with debugging (Bug#12118).
670 * lisp.h (ASET) [ENABLE_CHECKING]: Ignore ARRAY_MARK_FLAG when
671 checking subscripts; problem introduced with the recent
672 "ASET (a, i, v)" rather than "AREF (a, i) = v" patch.
673 (ARRAY_MARK_FLAG): Now a macro as well as a constant,
674 since it's used in non-static inline functions now.
676 * xfaces.c (face_at_buffer_position, face_for_overlay_string):
677 Don't assume buffer size fits in 'int'. Remove unused local.
679 Use C99-style 'extern inline' if available.

697 * composite.c (COMPOSITE_INLINE):
698 * dispnew.c (DISPEXTERN_INLINE):
699 * sysdep.c (SYSTIME_INLINE):

702 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
703 (INLINE_HEADER_END): New macros.
704 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

726 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
728 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
729 This how ASET and AREF are supposed to work, and makes
730 it easier to think about future improvements. See
731 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
732 * charset.h (set_charset_attr): New function.

986 does that unconditionally. Remove file, which is now empty.
988 * s/freebsd.h, s/gnu-linux.h, s/sol2-6.h, s/unixware.h:
989 Remove empty files.
991 2012-07-30 Paul Eggert <eggert@cs.ucla.edu>
993 Export to GDB most of lisp.h's remaining object-like macros.

1005 Now constants, for GDB, as well as macros, for static initializers.
1006 (CHAR_TABLE_STANDARD_SLOTS, CHAR_TABLE_EXTRA_SLOTS):
1007 Move to after the definition of struct Lisp_Char_Table,
1008 since the former now needs that type defined.

1109 * w32inevt.c: Include w32inevt.h.
1110 (w32_read_console_input): New inline function, calls either
1111 ReadConsoleInputA or ReadConsoleInputW, depending on the value of
1112 w32_console_unicode_input.
1113 (fill_queue): Call w32_read_console_input instead of ReadConsoleInput.
1114 (w32_kbd_patch_key, key_event): Use the codepage returned by
1115 GetConsoleCP, rather than the ANSI codepage returned by GetLocaleInfo.
1116 (key_event): use uChar.UnicodeChar only if
1117 w32_console_unicode_input is non-zero.
1119 * w32console.c: Include w32heap.h.

1144 * alloc.c (listn): Fix the order the arguments are consed onto the
1145 list.
1147 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
1148 enumeration constants, as PURE and HEAP are too general, and clash
1149 with other headers and sources, such as gmalloc.c and the
1150 MS-Windows system headers. All users changed.
1152 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
1154 Revert last save_excursion_save and save_excursion_restore changes.
1155 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

1165 2012-07-27 Paul Eggert <eggert@cs.ucla.edu>
1167 Improve GDB symbol export (Bug#12036).
1168 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
1169 arms of an 'if', not using conditional expressions; otherwise GDB
1170 complains about the types in the unevaluated arm when the argument
1171 is an integer literal.
1172 (xgetint): Simplify expression.
1173 * alloc.c (gdb_make_enums_visible): New constant. This ports to
1174 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
1175 Zaretskii in <http://bugs.gnu.org/12036#13>.
1176 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
1177 needed now that we have gdb_make_enums_visible.
1178 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
1179 (enum enum_USE_LSB_TAG):
1180 New enum types, packaging up enums that need to be exported to GDB.
1182 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>

1198 * xdisp.c (syms_of_xdisp): Likewise.
1199 * xfns.c (syms_of_xfns): Likewise.
1201 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
1203 Fast save_excursion_save and save_excursion_restore.
1204 * lisp.h (struct Lisp_Excursion): New data type.
1205 (PVEC_EXCURSION): New pseudovector type.
1206 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
1207 to deal with it. Adjust comments.
1208 (init_marker, attach_marker): New prototype.
1209 (unchain_marker): Adjust prototype.

1218 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
1220 Fix export of symbols to GDB (Bug#12036).
1221 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
1222 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
1223 emacs.c, as this is a more-suitable home. Had this been done earlier
1224 the fix for 12036 would have avoided some of the problems noted in
1225 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
1226 would have been more obvious.
1227 * emacs.c: Do not include <verify.h>; no longer needed.
1228 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
1229 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
1230 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
1231 Remove; now done in lisp.h.
1232 * lisp.h (PUBLISH_TO_GDB): New macro.

1234 (DATA_SEG_BITS): Use it.
1235 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
1236 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
1237 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
1238 not be usable in #if. This simplifies things.
1240 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
1242 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
1244 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
1246 Simplify export of symbols to GDB (Bug#12036).
1247 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
1248 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
1249 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
1250 Adjust to changes in lisp.h and emacs.c, by using
1251 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
1252 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
1253 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
1254 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
1255 instead of gdb_valbits.
1256 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
1257 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
1258 instead of gdb_array_mark_flag.
1259 (xboolvector): Get size from $->size, not $->header.size.
1260 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
1261 (xreload, hook-run, hookpost-run): Remove.
1262 * emacs.c: Include <verify.h>.
1263 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
1264 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
1265 Remove.
1266 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
1267 (gdb_USE_LSB_TAG): New enum constants.
1268 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
1269 Also define these as enum constants, so they're visible to GDB.
1270 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
1271 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
1272 as constants, so they're visible to GDB.

1274 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
1275 Now enum constants, not macros, so they're visible to GDB.
1276 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
1277 more convenient now. All uses changed.
1278 (VALMASK) [USE_LSB_TAG]: Also define in this case.
1279 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
1281 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>
1283 Explicitly free restriction data that are not needed anymore.
1284 * editfns.c (save_restriction_restore): Free restriction data.
1286 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
1288 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
1289 add argument, tune behavior, and adjust all callers.
1291 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
1293 Use typedef for EMACS_INT, EMACS_UINT.
1294 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
1295 than macros. This simplifies debugging in the usual case, since
1296 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
1297 and it allows expressions involving EMACS_INT casts.
1298 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
1300 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>
1302 * nsterm.m (ns_read_socket): Return early if there is a modal
1303 window (Bug#12043).
1305 2012-07-25 Martin Rudalics <rudalics@gmx.at>

1308 that FOCUS-FRAME can be omitted.
1310 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
1312 Adjust buffer text indirection counters at the end of Fkill_buffer.
1313 * buffer.c (Fkill_buffer): Adjust indirection counters when the
1314 buffer is definitely dead. This should really fix an issue reported
1315 by Christoph Scholtes again. (Bug#12007).
1316 (init_buffer_once): Initialize indirection counters of
1317 buffer_defaults and buffer_local_symbols (for sanity and safety).
1319 2012-07-24 Eli Zaretskii <eliz@gnu.org>
1321 * xdisp.c (init_iterator): Don't compute dimensions of truncation
1322 and continuation glyphs on tooltip frames, leave them at zero.
1323 Avoids continued lines in tooltips. (Bug#11832)
1325 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
1327 Simplify copy_overlay.
1328 * buffer.c (copy_overlay): Simplify. Use build_marker.

1334 or invalid. (Bug#12025)
1336 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
1337 it signals an error when a tooltip frame is being created.
1339 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
1341 Cleanup miscellaneous objects allocation and initialization.
1342 * alloc.c (allocate_misc): Change to static. Add argument to
1343 specify the subtype. Adjust comment and users.
1344 (build_overlay): New function.
1345 * buffer.c (copy_overlays, Fmake_overlay): Use it.
1346 * lisp.h (struct Lisp_Overlay): Remove obsolete comment.
1347 (allocate_misc): Remove prototype.
1348 (build_overlay): Add prototype.
1350 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
1352 Swap buffer text indirection counters in Fbuffer_swap_text.
1353 * buffer.c (Fbuffer_swap_text): Swap indirections too.
1354 This avoids crash reported by Christoph Scholtes at
1355 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
1357 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
1359 * nsmenu.m (Popdown_data): New struct.
1360 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
1361 free Popdown_data.
1362 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
1363 (initWithContentRect): Make imgView and contentView non-static

2118 The functional style also makes code easier to read and maintain.
2119 * systime.h: Include <sys/time.h> on all hosts, not just if
2120 WINDOWSNT, since 'struct timeval' is needed in general.

2136 (add_emacs_time, sub_emacs_time): New functions.
2137 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.

2154 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
2155 (menu_separator_name_p):

2157 Prefer memcmp to strncmp when either will do.
2158 * nsterm.m: Include <ftoastr.h>.
2159 (ns_get_color):
2160 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
2161 Prefer snprintf to strncpy.
2162 * nsterm.m (ns_term_init):
2163 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
2164 * nsterm.m (ns_term_init):
2165 Avoid the need for strncpy, by using build_string or
2166 make_unibyte_string directly. Use dtoastr, not snprintf.
2167 * process.c (Fmake_network_process): Diagnose service names that
2168 are too long, rather than silently truncating them or creating
2169 non-null-terminated names.

2204 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
2205 argument, adjust users accordingly. Use build_pure_c_string where

2241 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
2242 O_RDONLY already includes it).
2244 Stop ns builds setting the EMACSLOADPATH environment variable.
2245 * nsterm.m (ns_load_path): Rename from ns_init_paths.
2246 Now it does not set EMACSLOADPATH, just returns the load-path string.
2247 * nsterm.h: Update accordingly.
2248 * lread.c [HAVE_NS]: Include nsterm.h.
2249 (init_lread) [HAVE_NS]: Use ns_load_path.

2252 2012-07-09 Glenn Morris <rgm@gnu.org>
2254 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
2255 since the included bsd-common.h does so.
2257 Stop ns builds setting the EMACSPATH environment variable.
2258 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
2259 (ns_init_paths): Do not set EMACSPATH.
2260 * nsterm.h (ns_exec_path): Add it.
2261 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
2262 Use ns_exec_path.
2264 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
2266 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
2268 * process.c (wait_reading_process_output): 'waitchannels' was unset
2269 when read_kbd || !NILP (wait_for_cell); fix this.
2271 Add GCC-style 'const' attribute to functions that can use it.
2272 * character.h (char_resolve_modifier_mask):
2273 * keyboard.h (make_ctrl_char):
2274 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
2275 (init_character_once, next_almost_prime, init_fns, init_image)
2276 (flush_pending_output, init_sound):
2277 * mem-limits.h (start_of_data):
2278 * menu.h (finish_menu_items):

2281 Declare the dummy function with ATTRIBUTE_CONST.
2282 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
2283 Add decls with ATTRIBUTE_CONST.
2285 Minor improvements to make_formatted_string.
2286 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
2287 where int is good enough, as vsprintf returns an int.
2288 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
2290 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
2292 Use make_formatted_string to avoid double length calculation.
2293 * lisp.h (make_formatted_string): New prototype.
2294 * alloc.c (make_formatted_string): New function.
2295 * buffer.c (Fgenerate_new_buffer_name): Use it.

2300 (x_report_frame_params): Likewise.
2301 * image.c (gs_load): Likewise.
2302 * minibuf.c (get_minibuffer): Likewise.

2315 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
2317 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
2319 Move marker debugging code under MARKER_DEBUG.
2320 * marker.c (MARKER_DEBUG): Move marker debugging code under
2321 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
2322 for bootstrap with --enable-checking (~3x slowdown reported
2323 by Juanma Barranquero <lekktu@gmail.com>).
2324 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
2326 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
2328 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
2329 See <http://bugs.gnu.org/11825#29>.
2331 2012-07-08 Eli Zaretskii <eliz@gnu.org>
2333 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
2334 has no font, use the frame's font. (Bug#11813)
2335 (display_line): Add commentary about displaying truncation glyphs
2336 on GUI frames.
2337 (produce_special_glyphs): Move here from term.c.
2339 * term.c (produce_special_glyphs): Move to xdisp.c.
2341 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
2342 section.
2344 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
2346 * xdisp.c (display_line): Avoid warning about implicit declaration
2347 of FRAME_FONT.
2349 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
2351 * lisp.h: Remove empty conditional.
2353 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
2355 * lread.c (load_path_check): Now static.
2357 Fix some minor --with-ns problems found by static checking.
2358 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
2359 (x_set_font) [!HAVE_X_WINDOWS]:
2360 * image.c (xpm_load_image) [HAVE_NS]:
2361 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
2362 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
2363 Remove unused local.
2364 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
2365 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
2366 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
2367 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
2368 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
2369 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
2370 Fix pointer signedness problem.
2371 * xfaces.c (FRAME_X_FONT_TABLE):
2372 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
2374 2012-07-07 Glenn Morris <rgm@gnu.org>
2376 * lread.c (load_path_check): New function, split from init_lread.
2377 (init_lread): Reorganize. Motivation:
2378 If EMACSLOADPATH is set, check/warn about that rather than the
2379 defaults, which we are not going to use. Hence we can remove
2380 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
2381 Don't warn if site-lisp directories are missing.
2382 If not installed, start from a blank load-path, since
2383 PATH_LOADSEARCH refers to the eventual installation directories.
2385 2012-07-07 Eli Zaretskii <eliz@gnu.org>
2387 Support truncation and continuation glyphs on GUI frames, when
2388 fringes are disabled. (Bug#11832)
2389 * xdisp.c (init_iterator): Get dimensions of truncation and
2390 continuation glyphs even if on GUI frames.
2391 Adjust it->last_visible_x on GUI frames when the left or right fringes,
2392 or both, are absent.
2393 (start_display, move_it_in_display_line_to): Handle the case of a
2394 GUI frame without a fringe to display continuation or truncation
2395 glyphs.
2396 (insert_left_trunc_glyphs): Support GUI frames: make sure
2397 truncation glyphs overwrite enough glyphs from the current line to
2398 have sufficient space in pixels.
2399 (display_line): Support truncation and continuation glyphs on GUI
2400 frames. If some spare pixels are left on the line after inserting
2401 the truncation glyphs, fill that space with a stretch glyph of a
2402 suitably computed width.
2404 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
2405 produce_glyphs, to support GUI sessions.
2407 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
2409 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
2411 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
2413 Do not require float-time's arg to fit in time_t (Bug#11825).
2414 This works better on hosts where time_t is unsigned, and where
2415 float-time is applied to the (negative) difference between two times.
2416 * editfns.c (decode_time_components): Last arg is now double *,
2417 not int *, and means to store all the result as a double, without
2418 worrying about whether the seconds part fits in time_t.
2419 All callers changed.
2420 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
2421 All callers changed.
2422 (Ffloat_time): Do not fail merely because the specified time falls
2423 outside of time_t range.
2425 2012-07-07 Glenn Morris <rgm@gnu.org>
2427 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

2434 Update dependencies.
2436 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
2438 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
2440 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).

2442 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
2443 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
2444 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
2445 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
2447 * xfont.c (compare_font_names): Redo to omit the need for casts.
2449 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
2451 * xfns.c (Fx_change_window_property): Doc fix.
2452 * w32fns.c (Fx_change_window_property): Doc fix.
2454 * w32fns.c (Fx_window_property): Accept the same arguments as the
2455 X Windows version. Doc fix.
2456 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
2458 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
2459 Eli Zaretskii <eliz@gnu.org>
2461 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
2462 Windows-specific code from nt/config.nt moved here.
2463 Obsolete settings removed.
2465 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
2467 * process.c: Avoid unnecessary calls to gettime.
2468 (wait_reading_process_output): Don't get the time of day
2469 when gobbling data immediately and not waiting, as there's no need
2470 for it in that case. This removes a FIXME.
2472 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
2474 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
2475 is defined (Bug#11768).
2477 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2479 Fix marker debugging code.
2480 * marker.c (byte_char_debug_check): Do not perform the check
2481 if buffer is not multibyte.
2482 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
2483 Call byte_char_debug_check with correct arguments.
2485 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2487 Compile marker debugging code only if ENABLE_CHECKING is defined.
2488 * marker.c (byte_char_debug_check, count_markers):
2489 Use only if ENABLE_CHECKING is defined.
2490 (byte_debug_flag): Remove.
2491 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
2492 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
2494 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2496 Avoid code repetition in marker-related functions.
2497 * marker.c (attach_marker): New function.
2498 (Fset_marker, set_marker_restricted, set_marker_both)
2499 (set_marker_restricted_both): Use it.
2500 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
2501 Consistently rename charno to charpos.
2502 (marker_position): Add eassert.
2503 (marker_byte_position): Convert to eassert.

2520 (save_restriction_save): Use build_marker.
2521 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
2522 * window.c (save_window_save): Likewise.
2524 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2526 Do not use Fdelete_overlay in delete_all_overlays
2527 to avoid redundant calls to unchain_overlay.
2528 * buffer.c (drop_overlay): New function.
2529 (delete_all_overlays, Fdelete_overlay): Use it.
2530 * minibuf.c (get_minibuffer): Fix comment.
2532 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
2534 Port to OpenBSD 5.1 amd64.
2535 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
2536 This is needed for OpenBSD, and should be harmless on all BSD systems.
2537 Also, include <sys/sysctl.h>, as it should be available on all
2538 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
2539 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
2540 use p_pid member, not kp_proc.pid.
2542 2012-07-06 Glenn Morris <rgm@gnu.org>
2544 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
2546 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
2548 More xmalloc and related cleanup.
2549 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
2550 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:
2551 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c:

2557 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
2558 * xterm.c:
2559 Omit needless casts involving void * pointers and allocation.
2560 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
2561 as the former is more robust if P's type is changed.
2562 Prefer xzalloc to xmalloc + memset 0.
2563 Simplify malloc-or-realloc to realloc.
2564 Don't worry about xmalloc returning a null pointer.
2565 Prefer xstrdup to xmalloc + strcpy.
2566 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
2567 growing it.
2568 * keyboard.c (apply_modifiers_uncached): Prefer local array to
2569 alloca of a constant.
2571 2012-07-05 Eli Zaretskii <eliz@gnu.org>
2573 * xdisp.c (display_line): Fix horizontal pixel coordinates when
2574 hscroll is larger than the line width. Fixes long and futile
2575 looping inside extend_face_to_end_of_line (on a TTY) producing
2576 glyphs that are not needed and thrown away.
2578 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
2580 * marker.c (set_marker_restricted_both): Simplify by using
2581 clip_to_bounds.

2594 followed by gtk_box_set_homogeneous (Bug#11768).
2595 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
2596 (update_theme_scrollbar_width, xg_create_scroll_bar):
2597 Use gtk_scrollbar_new (Bug#11768).
2598 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
2599 (is_box_type): New function (Bug#11768).
2600 (xg_tool_item_stale_p): Call is_box_type.
2601 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
2602 with default display (Bug#11768).
2604 2012-07-05 Eli Zaretskii <eliz@gnu.org>
2606 * xdisp.c (window_hscroll_limited): New function.
2607 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
2608 coordinates when window's hscroll is set to insanely large
2609 values. (Bug#11857)
2611 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
2613 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
2614 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
2616 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>

2672 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
2674 * fileio.c (time_error_value): Check the right error number.
2675 Problem reported by Troels Nielsen in
2676 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
2678 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2680 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
2681 This should be fixed in a better way; see Eli Zaretskii in
2682 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
2683 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
2685 * fileio.c (time_error_value): Rename from special_mtime.
2686 The old name's problems were noted by Eli Zaretskii in
2687 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
2689 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
2690 This variable's comment says Emacs needs at least one GDB-visible
2691 symbol of type enum pvec_type, to work around GDB problems.
2692 The symbol's value doesn't matter.
2694 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
2695 that causes compilation to fail on pre-C99 compilers.
2697 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
2699 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
2700 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
2702 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2704 * buffer.c (init_buffer_once): Fix initialization of
2705 headers for buffer_defaults and buffer_local_symbols.
2706 Reported by Juanma Barranquero <lekktu@gmail.com>.
2708 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
2710 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
2711 * lisp.h (enum pvec_type): Use fewer bits.
2712 (PSEUDOVECTOR_SIZE_BITS): New constant.
2713 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
2714 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
2715 change in pvec_type.
2716 (PSEUDOVECTOR_TYPEP): New macro.
2717 (TYPED_PSEUDOVECTORP): Use it.
2718 * fns.c (internal_equal): Adapt code to extract pvectype.
2719 * emacs.c (gdb_pvec_type): Update type.
2720 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.

2722 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
2723 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
2724 (sweep_vectors): Use it. Use local var `total_bytes' instead of
2725 abusing vector->header.next.nbytes.
2726 (live_vector_p): Use PVEC_TYPE.
2727 (mark_object): Adapt code to extract pvectype. Use switch.
2729 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2731 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
2732 Tighten new eassert a bit.
2734 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2736 Fix compilation with --enable-gcc-warnings and -O1
2737 optimization level.
2738 * doprnt.c (doprnt): Change type of tem to int, initialize
2739 to avoid compiler warning. Add eassert.
2740 * search.c (simple_search): Initialize match_byte to avoid
2741 compiler warning. Add eassert.
2743 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2745 Avoid weird behavior with large horizontal scrolls.
2746 Without this change, for example, large hscroll values would
2747 mess up Emacs's display on Fedora 15 x86, presumably due to
2748 overflows in int calculations in the display code.
2749 Also, if buffers had long lines, Emacs would freeze.
2750 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
2751 (set_window_hscroll): New function, containing the old guts of
2752 Fset_window_hscroll. Return the clipped value.
2753 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
2754 This avoids the need to check against PTRDIFF_MAX.
2756 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
2758 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2760 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
2762 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2764 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
2765 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
2766 since GCC 4.4.6 issues a bogus warning for them.
2768 Fix bugs in file timestamp newness comparisons.
2769 * fileio.c (Ffile_newer_than_file_p):
2770 * lread.c (Fload): Use full timestamp resolution of files,
2771 not just the 1-second resolution, so that files that are only
2772 slightly newer still count as newer.
2773 * fileio.c (Ffile_newer_than_file_p): Don't assume file
2774 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
2776 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
2778 * fileio.c: Improve handling of file time marker. (Bug#11852)
2779 (special_mtime): New function.
2780 (Finsert_file_contents, Fverify_visited_file_modtime):
2781 Use it to set special mtime values consistently.
2783 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
2785 * fileio.c (Finsert_file_contents): Properly handle st_mtime
2786 marker for non-existing file. (Bug#11852)
2788 2012-07-03 Glenn Morris <rgm@gnu.org>
2790 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
2791 and did not make it into globals.h).
2793 2012-07-03 Tom Tromey <tromey@redhat.com>
2795 * window.c (Fset_window_margins, Fset_window_fringes)
2796 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
2797 * textprop.c (Fprevious_property_change): No longer static.
2798 * syntax.c (Fsyntax_table_p): No longer static.
2799 * process.c (Fget_process, Fprocess_datagram_address): No longer
2800 static.
2801 * keymap.c (Flookup_key, Fcopy_keymap): No longer static.
2802 * keyboard.c (Fcommand_execute): No longer static.
2803 Remove EXFUN.
2804 * insdel.c (Fcombine_after_change_execute): No longer static.
2805 * image.c (Finit_image_library): No longer static.

2818 * buffer.h: Remove EXFUNs.
2819 * dispextern.h: Remove EXFUNs.
2820 * intervals.h: Remove EXFUNs.
2821 * fontset.h: Remove EXFUN.
2822 * font.h: Remove EXFUNs.
2823 * dosfns.c (system_process_attributes): Remove EXFUN.
2824 * keymap.h: Remove EXFUNs.
2825 * lisp.h: Remove EXFUNs.
2826 * w32term.h: Remove EXFUNs.
2827 * window.h: Remove EXFUNs.
2828 * xsettings.h: Remove EXFUN.
2829 * xterm.h: Remove EXFUN.
2831 2012-07-03 Glenn Morris <rgm@gnu.org>
2833 * lisp.h (Frandom): Make it visible to C.
2834 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
2835 buffer for invisible buffers. (Bug#1229)
2837 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2839 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
2840 values which aren't power of 2.
2841 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
2842 Verify it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
2843 accordingly.
2845 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
2847 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
2849 * alloc.c (mark_object): Revert part of last patch to use `switch'.
2851 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2853 * alloc.c (allocate_vector_block): Remove redundant
2854 calls to mallopt if DOUG_LEA_MALLOC is defined.
2855 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
2856 avoid calls to mallopt if zero_vector is returned.
2858 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2860 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
2861 is enabled, avoid dereferencing NULL current_sblock if
2862 running undumped.
2864 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2866 Cleanup basic buffer management.
2867 * buffer.h (struct buffer): Change layout to use generic vector
2868 marking code. Fix some comments. Change type of 'clip_changed'
2869 to bitfield. Remove unused #ifndef old.
2870 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
2871 (GET_OVERLAYS_AT): Fix indentation.
2872 (for_each_per_buffer_object_at): New macro.
2873 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
2874 (Fbuffer_local_variables): Use it.
2875 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
2876 * alloc.c (allocate_buffer): Adjust to match new layout of
2877 struct buffer. Fix comment.
2878 (mark_overlay): New function.
2879 (mark_buffer): Use it. Use mark_vectorlike to mark normal
2880 Lisp area of struct buffer.
2881 (mark_object): Use it. Adjust marking of misc objects
2882 and related comments.
2884 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
2886 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
2887 wrapper that is not needed because the wrapped code is a no-op (zero
2888 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
2889 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
2891 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
2893 * alloc.c (mark_buffer): Simplify. Remove prototype.
2894 (mark_object): Add comment. Reorganize marking of vector-like
2895 objects. Use CHECK_LIVE for all vector-like objects except buffers
2896 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
2897 Avoid redundant calls to mark_vectorlike for bool vectors.
2899 2012-06-30 Glenn Morris <rgm@gnu.org>
2901 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
2903 * epaths.in (PATH_SITELOADSEARCH): New.
2904 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
2905 This is rather than relying on --enable-locallisppath elements
2906 having "site-lisp" in their names. (Bug#10208#25, 11658)
2908 2012-06-30 Eli Zaretskii <eliz@gnu.org>
2910 * w32proc.c (sys_select): Accept and ignore one more argument.
2912 * w32.c (emacs_gnutls_pull): Call select with one more argument.
2914 * sysselect.h [DOS_NT]: Don't include sys/select.h.
2915 (pselect) [!MS_DOS]: Redirect to sys_select.
2917 * sysdep.c: Don't include dos.h and dosfns.h.
2919 * process.c (sys_select):
2920 * msdos.c (sys_select): Accept one more argument and ignore it.
2922 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
2923 adapt data types and code to that.
2925 * dosfns.c:
2926 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
2927 which clashes with the gnulib function of the same name.
2929 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
2931 * font.c (font_style_to_value, font_style_symbolic)
2932 (font_prop_validate_style): Add type checks for values in
2933 font_style_table.
2935 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
2936 argument.
2937 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
2938 uses.
2940 2012-06-29 Eli Zaretskii <eliz@gnu.org>
2942 * xdisp.c (try_window_id): Undo last change.
2944 * w32.c (getwd): Adjust commentary about startup_dir.
2945 (init_environment): Always call sys_access, even in non-MSVC
2946 builds. Don't chdir to the directory of the Emacs executable.
2947 This undoes code from 1997 which was justified by the need to
2948 "avoid conflicts when removing and renaming directories". But its
2949 downside was that every relative file name was being interpreted
2950 relative to the directory of the Emacs executable, which can never
2951 be TRT. In particular, it broke sys_access when called with
2952 relative file names.
2953 (sys_access): Map GetLastError to errno.
2955 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2957 * window.h (struct window): Change type of 'fringes_outside_margins'
2958 to bitfield. Fix comment. Adjust users accordingly.
2959 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
2960 Adjust comment.
2961 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
2962 to ptrdiff_t.
2964 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
2966 * gnutls.c (emacs_gnutls_handshake):
2967 Add QUIT to make the loop interruptible.
2969 2012-06-29 Glenn Morris <rgm@gnu.org>
2971 * charset.c (init_charset): Make lack of etc/charsets fatal.
2973 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2975 * editfns.c (region_limit): Fix type mismatch.
2977 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2979 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
2980 undefined. Convert from xassert to eassert.
2981 * nsmenu.m: Convert from xassert to eassert.
2982 * nsterm.m: Likewise.
2984 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>

2988 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
2990 Avoid integer overflow on scroll-left and scroll-right.
2991 * window.c (HSCROLL_MAX): New macro.
2992 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
2993 overflow when requested scroll falls outside ptrdiff_t range.
2995 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
2997 * window.h (struct window): Change type of 'hscroll',
2998 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
2999 'last_modified' and 'last_overlay_modified' to EMACS_INT.
3000 Adjust users accordingly.
3001 * xdisp.c (try_cursor_movement): Replace type check with eassert.
3002 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
3003 from EMACS_INT to ptrdiff_t.
3004 (make_window): Omit redundant initialization.
3006 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
3008 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
3010 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
3012 * window.h (struct window): Change type of 'use_time' and

3021 * dispextern.h (GLYPH_DEBUG): Now defined in config.h if
3022 enabled with --enable-checking=[all,glyphs] configure option.
3023 Fix GLYPH_DEBUG usage assuming that it may be undefined,
3024 adjust comments accordingly.
3025 * dispnew.c: Fix GLYPH_DEBUG usage assuming that it may be
3026 undefined, adjust comments accordingly.

3066 2012-06-27 Stefan Monnier <monnier@iro.umontreal.ca>
3068 * fns.c (maybe_resize_hash_table): Output message when growing the
3069 purify-hashtable.
3071 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
3073 * alloc.c (allocate_string_data): Remove dead code.
3074 * xsettings.c (XSETTINGS_FONT_NAME): Move under HAVE_XFT to
3075 avoid GCC warning about unused macro.
3077 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
3079 * alloc.c (allocate_string): Omit intervals initialization.
3080 * alloc.c (make_uninit_multibyte_string): Initialize intervals
3081 as in make_pure_string and make_pure_c_string.

3115 _stricmp and _strnicmp.
3116 (HAVE_STRCASECMP, HAVE_STRNCASECMP): Define to 1.
3118 2012-06-26 Dmitry Antipov <dmantipov@yandex.ru>
3120 * alloc.c (allocate_window): Zero out non-Lisp part of newly

3135 2012-06-26 Dmitry Antipov <dmantipov@yandex.ru>
3137 * alloc.c: Remove build_string.
3138 * lisp.h: Define build_string as static inline. This provides
3139 a better opportunity to optimize away calls to strlen when the
3140 function is called with compile-time constant argument.
3141 * image.c (imagemagick_error): Convert to build_string.
3142 * w32proc.c (sys_spawnve): Likewise.
3143 * xterm.c (x_term_init): Likewise.
3145 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
3147 Use sprintf return value instead of invoking strlen on result.
3148 In the old days this wasn't portable, since some sprintf
3149 implementations returned char *. But they died out years ago and
3150 Emacs already assumes sprintf returns int.
3151 Similarly for float_to_string.
3152 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
3153 * ccl.c (ccl_driver):
3154 * character.c (string_escape_byte8):

3157 * print.c (print_object):
3158 * xdisp.c (message_dolog):
3159 * xfns.c (syms_of_xfns):
3160 Use sprintf or float_to_string result to avoid need to call strlen.
3161 * data.c (Fnumber_to_string):
3162 Use make_unibyte_string, since the string must be ASCII.
3163 * lisp.h, print.c (float_to_string): Now returns int length.
3164 * term.c (produce_glyphless_glyph):
3165 Use sprintf result rather than recomputing it.
3167 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
3168 * Makefile.in (ALL_CFLAGS):
3169 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
3170 * gmalloc.c, regex.c: Include <config.h> unconditionally.

3174 * dispextern.h (xstrcasecmp): Define to library function
3175 strcasecmp if available.

3259 Remove unnecessary forward decls.
3261 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
3263 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
3264 * lisp.h (WAIT_READING_MAX): New macro.
3265 * dispnew.c (Fsleep_for, sit_for):
3266 * keyboard.c (kbd_buffer_get_event):
3267 * process.c (Faccept_process_output):
3268 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
3269 This improves on the previous patch, which introduced a bug
3270 when time_t is unsigned and as wide as intmax_t.
3271 See <http://bugs.gnu.org/9000#51>.
3273 2012-06-23 Eli Zaretskii <eliz@gnu.org>
3275 * dispnew.c (sit_for, Fsleep_for):
3276 * keyboard.c (kbd_buffer_get_event):

3289 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
3290 Privately reported by Herbert J. Skuhra.
3291 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
3292 All uses changed.
3293 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
3294 not make_lisp_timeval, when the argument is of type EMACS_TIME.
3296 2012-06-23 Eli Zaretskii <eliz@gnu.org>
3298 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
3299 last argument of make_unibyte_string.

3302 language ID in the event parameters.
3304 * w32term.c (w32_read_socket): Put the new keyboard codepage into
3305 event.code, not the obscure "character set ID".

3336 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
3338 Support higher-resolution time stamps (Bug#9000).
3339 The time stamps are only nanosecond-resolution at the C level,
3340 since that's the best that any real-world system supports now.
3341 But they are picosecond-resolution at the Lisp level, as that's
3342 easy, and leaves room for future OS improvements.
3344 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
3345 (LIBES): Use it.
3347 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
3348 Don't get current time unless it's needed.
3350 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
3351 now provides it if it's absent.
3352 (start_atimer): Port to higher-res time stamps.
3353 Check for time stamp overflow. Don't get current time more
3354 often than is needed.
3356 * buffer.h (struct buffer): Buffer modtime now has high resolution.
3357 Include systime.h, not time.h.
3358 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
3360 * dired.c: Include stat-time.h.
3361 (Ffile-attributes): File times now have higher resolution.
3363 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
3364 (struct image): Timestamp now has higher resolution.
3366 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
3367 has at least microseconds now. All uses removed.
3368 (update_frame, update_single_window, update_window, update_frame_1)
3369 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
3371 * editfns.c (time_overflow): Now extern.
3372 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
3373 (float-time, Fformat_time_string, Fcurrent_time_string)
3374 (Fcurrent_time_zone): Accept and generate higher-resolution
3375 time stamps.
3376 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
3377 (decode_time_components, lisp_seconds_argument): New functions.
3378 (make_time): Now static.
3379 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
3380 Report an error if the time is invalid, rather than having the caller
3381 do that.
3383 * fileio.c: Include <stat-time.h>
3384 (Fcopy_file): Copy higher-resolution time stamps.
3385 Prefer to set the time stamp via a file descriptor if that works.
3386 (Fset_file_times, Finsert_file_contents, Fwrite_region)
3387 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
3388 (Fvisited_file_modtime, Fset_visited_file_modtime):
3389 Support higher-resolution time stamps.
3391 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
3393 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
3395 * image.c (prepare_image_for_display, clear_image_cache)
3396 (lookup_image): Port to higer-resolution time stamps.
3398 * keyboard.c (start_polling, bind_polling_period):
3399 Check for time stamp overflow.
3400 (read_char, kbd_buffer_get_event, timer_start_idle)
3401 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
3402 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
3403 Port to higher-resolution time stamps. Do not assume time_t is signed.
3404 (decode_timer): New function. Timers are now vectors of length 9,
3405 not 8, to accommodate the picosecond component.
3406 (timer_check_2): Use it.
3408 * nsterm.m (select_timeout, timeval_subtract): Remove.
3409 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
3410 as they're a bit more accurate and handle overflow better.
3411 (ns_select): Change prototype to be compatible with pselect.
3412 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
3413 * nsterm.h (ns_select): Adjust prototype.
3415 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
3416 us-resolution time stamps.
3417 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
3419 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
3421 * lisp.h (time_overflow): New decl.
3422 (wait_reading_process_output): First arg is now intmax_t, not int,
3423 to accommodate larger waits.
3425 * process.h (struct Lisp_Process.read_output_delay):
3426 Now counts nanoseconds, not microseconds.
3427 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
3428 EMACS_HAS_USECS.
3429 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
3430 (wait_reading_process_output):
3431 Port to ns-resolution time stamps.
3432 (Faccept_process_output, wait_reading_process_output):
3433 Check for time stamp overflow. Do not assume time_t is signed.
3434 (select_wrapper): Remove; we now use pselect.
3435 (Fprocess_attributes): Now generates ns-resolution time stamps.
3437 * sysdep.c: Include utimens.h. Don't include utime.h
3438 or worry about struct utimbuf; gnulib does that for us now.
3439 (gettimeofday): Remove; gnulib provides a substitute.
3440 (make_timeval): New function.
3441 (set_file_times): Now sets ns-resolution time stamps.
3442 New arg FD; all uses changed.
3443 (time_from_jiffies, ltime_from_jiffies, get_up_time)
3444 (system_process_attributes):
3445 Now returns ns-resolution time stamp. All uses changed.
3446 Check for time stamp overflow.
3448 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
3449 provides a substitute now.
3451 * systime.h: Include timespec.h rather than sys/time.h and time.h,
3452 since it guarantees struct timespec.
3453 (EMACS_TIME): Now struct timespec, so that we can support
3454 ns-resolution time stamps.
3455 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
3456 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
3457 (EMACS_USECS): Remove.
3458 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
3459 so multiply the arg by 1000 before storing it.
3460 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
3461 New macros.
3462 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
3463 Port to ns-resolution time stamps.
3464 (EMACS_TIME_NEG_P): Remove; replaced by....
3465 (EMACS_TIME_SIGN): New macro.
3466 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
3467 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
3468 (set_file_times, make_time, lisp_time_argument): Adjust signature.
3469 (make_timeval, make_lisp_time, decode_time_components): New decls.
3470 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
3471 that it mishandled time_t overflow. You can't compare by subtracting!
3472 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
3473 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
3475 * term.c: Include <sys/time.h>.
3476 (timeval_to_Time): New function, for proper overflow wraparound.
3477 (term_mouse_position, term_mouse_click): Use it.
3479 * undo.c (record_first_change): Support higher-resolution time stamps
3480 in the undo buffer.
3481 (Fprimitive_undo): Use them when restoring time stamps.
3483 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
3484 (w32_get_internal_run_time):
3485 Port to higher-resolution Emacs time stamps.
3486 (ltime): Now accepts single 64-bit integer, as that's more convenient
3487 for callers.
3489 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
3491 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
3492 for compatibility with pselect. Support ns-resolution time stamps.
3494 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
3496 * xselect.c (wait_for_property_change, x_get_foreign_selection):
3497 Check for time stamp overflow, and support ns-resolution time stamps.
3499 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
3500 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
3501 (timeval_subtract): Remove; no longer needed.
3502 (XTflash, XTring_bell, x_wait_for_event):
3503 Port to ns-resolution time stamps. Don't assume time_t is signed.
3505 2012-06-22 Chong Yidong <cyd@gnu.org>

3509 2012-06-22 Eli Zaretskii <eliz@gnu.org>
3511 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
3512 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
3513 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
3514 staticidx goes up to 1597 out of 1600 = 0x640.)
3516 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
3518 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
3519 Otherwise, the umask might be mistakenly 0 while handling input signals.
3521 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
3523 * minibuf.c (Fread_string): Bind minibuffer-completion-table.
3525 2012-06-19 Dmitry Antipov <dmantipov@yandex.ru>
3527 * alloc.c, bytecode.c, ccl.c, coding.c, composite.c, data.c, dosfns.c:
3528 * font.c, image.c, keyboard.c, lread.c, menu.c, minibuf.c, msdos.c:
3529 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
3530 access to `contents' member of Lisp_Vector objects with AREF and ASET
3531 where appropriate.
3533 2012-06-19 Chong Yidong <cyd@gnu.org>
3535 * frame.c (delete_frame): When selecting a frame on a different
3536 text terminal, do not alter the terminal's top-frame.
3538 * xdisp.c (format_mode_line_unwind_data): Record the target
3539 frame's selected window and its terminal's top-frame.
3540 (unwind_format_mode_line): Restore them.
3541 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
3542 Callers changed.
3543 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
3544 since tty frames can be explicitly named.
3545 (prepare_menu_bars): Likewise.
3547 * term.c (Ftty_top_frame): New function.
3549 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
3551 Port byte-code-meter to modern targets.
3552 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
3553 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
3554 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
3555 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
3556 (METER_1, METER_2): Simplify.
3558 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
3560 * data.c (Fdefalias): Return `symbol' (bug#11686).
3562 2012-06-18 Martin Rudalics <rudalics@gmx.at>
3564 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
3565 gets killed during executing of this function (Bug#11665).
3566 Try to always return Qt when the buffer has been actually killed.
3567 (Vkill_buffer_query_functions): In doc-string say that functions
3568 run by this hook should not change the current buffer.
3570 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
3572 Fix recently-introduced process.c problems found by static checking.
3573 * process.c (write_queue_push, write_queue_pop, send_process):
3574 Use ptrdiff_t, not int or EMACS_INT, for buffer lengths and offsets.
3575 (write_queue_pop): Fix pointer signedness problem.
3576 (send_process): Remove unused local.
3578 2012-06-17 Chong Yidong <cyd@gnu.org>
3580 * xdisp.c (redisplay_internal): No need to redisplay terminal
3581 frames that are not on top.
3583 2012-06-17 Troels Nielsen <bn.troels@gmail.com>
3585 * process.c (make_process): Initialize write_queue.
3586 (write_queue_push, write_queue_pop): New functions.

3588 writes (Bug#10815).
3590 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
3592 * lisp.h (eassert): Assume C89 or later.
3593 This removes the need for CHECK.
3594 (CHECK): Remove. Its comments about always evaluating its
3595 argument were confusing, as 'eassert' typically does not evaluate
3596 its argument.
3598 * coding.c (produce_chars): Use ptrdiff_t, not int.
3600 * xterm.c (x_draw_underwave): Check for integer overflow.
3601 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.
3603 2012-06-17 Jan Djärv <jan.h.d@swipnet.se>
3605 * nsterm.m (x_free_frame_resources): Move xfree so freed memory isn't
3606 referenced (Bug#11583).

3620 (Finternal_set_lisp_face_attribute, realize_x_face):
3621 Handle wave-style underline face attributes.
3622 * xterm.c (x_draw_underwave): New function.
3623 (x_draw_glyph_string): Use it.
3625 2012-06-16 Juanma Barranquero <lekktu@gmail.com>

3692 2012-06-16 Eli Zaretskii <eliz@gnu.org>
3694 * xdisp.c (set_cursor_from_row): Don't dereference glyphs_end.
3695 If all the glyphs of the glyph row came from strings, and we have no
3696 cursor positioning clues, put the cursor on the first glyph of the
3697 row.
3698 (handle_face_prop): Use chunk-relative overlay string index when
3699 indexing into it->string_overlays array. (Bug#11653)

3717 * .gdbinit (xgetint): Fix recently-introduced paren typo.
3718 Assume USE_2_TAGS_FOR_INTS.
3719 (xreload): Adjust $tagmask width to match recent lisp.h change.
3721 Simplify lisp.h in minor ways that should not affect code.
3722 * lisp.h (USE_2_TAGS_FOR_INTS): Remove, as it was always defined.
3723 (LISP_INT_TAG, case_Lisp_Int, LISP_STRING_TAG, LISP_INT_TAG_P)
3724 (LISP_INT1_TAG, enum Lisp_Type, XINT, XUINT, make_number):
3725 Simplify under the assumption that USE_2_TAGS_FOR_INTS is defined.
3726 (INTTYPEBITS): New macro, for clarity.
3727 (INTMASK, MOST_POSITIVE_FIXNUM): Use it.
3728 (LISP_INT1_TAG, LISP_STRING_TAG, LISP_INT_TAG_P):
3729 Simplify now that USE_LSB_TAG is always defined.
3730 (TYPEMASK, XINT) [USE_LSB_TAG]: Remove unnecessary cast.

3742 2012-06-13 Andreas Schwab <schwab@linux-m68k.org>
3744 * lisp.h (Lisp_Object) [CHECK_LISP_OBJECT_TYPE]: Define as struct
3745 instead of union.
3746 (XLI, XIL): Define.
3747 (XHASH, XTYPE, XINT, XUINT, make_number, XSET, XPNTR, XUNTAG):
3748 Use them.
3749 * emacs.c (gdb_use_struct): Rename from gdb_use_union.

3774 USE_LISP_UNION_TYPE + USE_LSB_TAG cleanup (Bug#11604)
3775 * alloc.c (make_number) [!defined make_number]:

3783 USE_LSB_TAG now is always defined to be either 0 or 1.
3784 All uses changed.
3785 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
3786 code works fine either way, and efficiency is not a concern here,
3787 as the union type is for debugging, not for production.
3788 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
3789 Use an inline function on all platforms when using the union type,
3790 since this is simpler and 'static inline' can be used portably
3791 within Emacs now.
3792 (LISP_INITIALLY_ZERO): New macro.
3793 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
3794 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.

3862 * dbusbind.c (XD_BASIC_DBUS_TYPE): Use dbus_type_is_valid and
3863 dbus_type_is_basic if available.
3864 (xd_extract_signed, xd_extract_unsigned): Rename from
3865 extract_signed and extract_unsigned, respectively. Adapt callers.
3867 2012-06-09 Chong Yidong <cyd@gnu.org>

3874 2012-06-08 Paul Eggert <eggert@cs.ucla.edu>
3876 * xdisp.c (vmessage): Treat frame message as multibyte.
3877 Without this change, (let ((§ 1)) (make-variable-buffer-local '§))
3878 would generate the diagnostic "Making \302\247 buffer-local while
3879 let-bound!".
3881 2012-06-08 Eli Zaretskii <eliz@gnu.org>
3883 * dispnew.c (showing_window_margins_p): Undo last change, which
3884 was done due to an inadvertent commit.

3896 * dispnew.c (showing_window_margins_p): Wrap in #if 0 to prevent unused
3897 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
3899 2012-06-08 Eli Zaretskii <eliz@gnu.org>
3901 * alloc.c (allocate_vectorlike): Fix last change.
3903 2012-06-08 Dmitry Antipov <dmantipov@yandex.ru>
3905 Block-based vector allocation of small vectors.
3906 * lisp.h (struct vectorlike_header): New field `nbytes',
3907 adjust comment accordingly.

3923 0 items. Allocate new vector from block if vector size is less than
3924 or equal to VBLOCK_BYTES_MAX.
3925 (Fgarbage_collect): Move all vector sweeping code to sweep_vectors.
3926 (init_alloc_once): Add call to init_vectors.
3928 2012-06-08 Stefan Monnier <monnier@iro.umontreal.ca>
3930 * eval.c (Fmacroexpand): Stop if the macro returns the same form.
3932 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
3934 * doprnt.c (doprnt): Truncate multibyte char correctly.
3935 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
3936 would mishandle a string argument "Xc" if X was a multibyte
3937 character of length 2: it would truncate after X's first byte
3938 rather than including all of X.
3940 2012-06-06 Chong Yidong <cyd@gnu.org>
3942 * buffer.c (word_wrap): Doc fix.

3989 * minibuf.c (Fassoc_string): Remove duplicate declaration.
3991 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
3992 Convert pctcpu and pctmem to Lisp float properly.
3993 Let the compiler fold better, as 100.0/0x8000 is exact.
3995 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
3997 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
3998 cons_block.
4000 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>

4004 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
4006 For a 'struct window', replace some Lisp_Object fields to
4007 bitfields where appropriate, remove unused fields.
4008 * window.h (struct window): Remove unused 'last_mark_x' and
4009 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
4010 change it's type from Lisp_Object to bitfield.
4011 Change type of 'force_start', 'optional_new_start',
4012 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
4013 fields from Lisp_Object to bitfield. Adjust users accordingly.
4015 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
4017 Pacify gcc -Wdouble-precision when using Xaw.
4018 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
4019 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
4020 Use 'float' consistently, rather than 'float' in most places
4021 and 'double' in a couple of places.
4023 2012-05-31 Eli Zaretskii <eliz@gnu.org>
4025 * xdisp.c (handle_stop): Detect whether we have overlay strings
4026 loaded by testing it->current.overlay_string_index to be
4027 non-negative, instead of checking whether n_overlay_strings is
4028 positive. (Bug#11587)
4030 2012-05-31 Chong Yidong <cyd@gnu.org>
4032 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
4034 * doc.c (Fsubstitute_command_keys): Doc fix.
4036 2012-05-31 Eli Zaretskii <eliz@gnu.org>
4038 * search.c (search_buffer): Remove calls to
4039 r_alloc_inhibit_buffer_relocation, as it is now called by
4040 maybe_unify_char, which was the cause of relocation of buffer text
4041 in bug#11519.
4043 2012-05-31 Eli Zaretskii <eliz@gnu.org>
4045 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
4046 for the duration of call to load_charset, to avoid problems with
4047 callers of maybe_unify_char that access buffer text through C
4048 pointers.
4050 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
4051 decrement the inhibition flag, instead of just setting or
4052 resetting it.
4054 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
4056 Remove obsolete '#define static' cruft.
4057 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
4058 This #undef was "temporary" in 2000; it is no longer needed
4059 now that '#define static' has gone away.
4060 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
4061 (gray_bitmap_bits): Remove; no longer needed.
4062 All uses replaced with definiens.

4074 (safe_bcopy): Remove decl; no longer has that name.
4075 (main): Coalesce #if into single bit of code, for simplicity.
4076 Cast pointers to uintptr_t, since standard libraries want integers
4077 and not pointers.
4078 * lisp.h (__executable_start): New decl.
4080 2012-05-31 Glenn Morris <rgm@gnu.org>
4082 * image.c (Fimagemagick_types): Doc fix.

4103 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
4105 Do not create empty overlays with the evaporate property (Bug#9642).
4106 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
4107 Bug#9642, but explicitly check that the buffer the overlay would
4108 be moved to is live and rearrange lines to make sure that errors
4109 will not put the overlay in an inconsistent state.
4110 (Fdelete_overlay): Cosmetics.
4112 2012-05-28 Eli Zaretskii <eliz@gnu.org>
4114 * w32term.c (my_bring_window_to_top): New function.
4115 (x_raise_frame): Use handle returned by DeferWindowPos, which
4116 could be different from the original one.
4117 Call my_bring_window_to_top instead of my_set_foreground_window.
4118 (Bug#11513)
4120 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
4121 by calling BringWindowToTop.

4126 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
4128 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
4129 This avoids undefined behavior that might cause the eassert
4130 to not catch an out-of-range value.
4132 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
4134 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
4135 Update dependencies.
4137 2012-05-27 Eli Zaretskii <eliz@gnu.org>

4144 when referring to sectname field in printf format.
4146 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
4148 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
4149 Only r_alloc_inhibit_buffer_relocation needed to be added;
4150 the others were already declared.
4152 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
4153 before checking whether it's out of range. Put the check inside
4154 eassert. See
4155 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
4157 2012-05-27 Ken Brown <kbrown@cornell.edu>
4159 * callproc.c (Fcall_process): Restore a line that was accidentally
4160 commented out in the 2011-02-13 change (bug#11547).
4162 2012-05-27 Eli Zaretskii <eliz@gnu.org>
4164 * lisp.h [REL_ALLOC]: Add prototypes for external functions
4165 defined on ralloc.c.
4167 * buffer.c [REL_ALLOC]: Remove prototypes of
4168 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
4169 they are now on lisp.h.
4171 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
4173 * search.c (search_buffer): Use it to inhibit relocation of buffer
4174 text while re_search_2 is doing its job, because re_search_2 is
4175 passed C pointers to buffer text. (Bug#11519)
4177 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
4178 Update value to 24.
4180 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
4181 state after an additional call to move_it_in_display_line_to, keep
4182 the values of it->max_ascent and it->max_descent found for the
4183 entire line.
4184 (pos_visible_p): Revert the comparison against bottom_y to what it
4185 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
4186 (Bug#11464)
4188 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
4190 Fix coding-related core dumps with gcc -ftrapv.
4191 The code was computing A - B, where A and B are pointers, and B is
4192 random garbage. This can lead to core dumps on platforms that
4193 have special pointer registers, and it also leads to core dumps on
4194 x86-64 when compiled with gcc -ftrapv. The fix is to compute
4195 A - B only when B is initialized properly.
4196 * coding.c (coding_set_source, coding_set_destination): Return void.
4197 (coding_change_source, coding_change_destinations): New functions,
4198 with the old behaviors of coding_set_source and coding_set_destination.
4199 All callers that need an offset changed to use these new functions.
4201 2012-05-26 Glenn Morris <rgm@gnu.org>
4203 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
4205 2012-05-26 Eli Zaretskii <eliz@gnu.org>
4207 Extend mouse support on W32 text-mode console.
4208 * xdisp.c (draw_row_with_mouse_face):
4209 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
4211 * w32console.c: Include window.h.
4212 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
4213 New functions.
4214 (initialize_w32_display): Initialize mouse-highlight data.
4216 * w32inevt.c: Include termchar.h and window.h.
4217 (do_mouse_event): Support mouse-autoselect-window. When the mouse
4218 moves, call note_mouse_highlight. If help_echo changed, call
4219 gen_help_event to produce help-echo message in the echo area.
4220 Call clear_mouse_face if mouse_face_hidden is set in the mouse
4221 highlight info.
4223 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
4225 * lread.c (read1): Simplify slightly to avoid an overflow warning
4226 with GCC 4.7.0 on x86-64.
4228 2012-05-26 Eli Zaretskii <eliz@gnu.org>
4230 * bidi.c (bidi_mirror_char): Revert last change: an int is
4231 definitely wide enough here.
4233 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
4235 Fix integer width and related bugs (Bug#9874).
4236 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
4237 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
4238 (string_bytes, check_sblock, allocate_string_data):

4243 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
4244 (mark_vectorlike):
4245 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4246 (allocate_pseudovector):
4247 Use int, not EMACS_INT, where int is wide enough.
4248 (inhibit_garbage_collection, Fgarbage_collect):
4249 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4250 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
4251 int might not be wide enough.
4252 (bidi_cache_search, bidi_cache_find, bidi_init_it)

4255 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
4256 (bidi_level_of_next_char, bidi_move_to_visually_next):
4257 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4258 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
4259 (Fkill_buffer, Fset_buffer_major_mode)
4260 (advance_to_char_boundary, Fbuffer_swap_text)

4263 (overlay_strings, recenter_overlay_lists)
4264 (adjust_overlays_for_insert, adjust_overlays_for_delete)
4265 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
4266 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
4267 (Foverlay_recenter, last_overlay_modification_hooks_used)
4268 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
4269 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4270 (validate_region): Omit unnecessary test for b <= e,
4271 since that's guaranteed by the previous test.
4272 (adjust_overlays_for_delete): Avoid pos + length overflow.
4273 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
4274 (report_overlay_modification):
4275 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4276 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
4277 Omit pointer cast, which isn't needed anyway, and doesn't work
4278 after the EMACS_INT -> ptrdiff_t change.
4279 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
4280 * buffer.h: Adjust decls to match defn changes elsewhere.

4285 not int, to avoid needless 32-bit limit on 64-bit hosts.
4286 (exec_byte_code): Use tighter memory-full test, one that checks
4287 for alloca overflow. Don't compute the address of the object just
4288 before an array, as that's not portable. Use EMACS_INT, not
4289 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
4290 * callint.c (Fcall_interactively):
4291 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4292 * callproc.c (call_process_kill, Fcall_process):
4293 Don't assume pid_t fits into an Emacs fixnum.
4294 (call_process_cleanup, Fcall_process, child_setup):

4296 (call_process_cleanup, Fcall_process, delete_temp_file)
4297 (Fcall_process_region):
4298 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4299 (Fcall_process): Simplify handling of volatile integers.
4300 Use int, not EMACS_INT, where int will do.
4301 * casefiddle.c (casify_object, casify_region, operate_on_word)
4302 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
4303 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4304 (casify_object): Avoid integer overflow when overallocating buffer.
4305 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
4306 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
4307 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
4308 * category.h (CATEGORYP): Don't assume arg is nonnegative.
4309 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
4310 integers are now checked earlier. All uses replaced with XINT.
4311 (ccl_driver):
4312 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4313 For CCL_MapSingle, check that content and value are in int range.
4314 (ccl_driver, Fregister_code_conversion_map):
4315 Check that Vcode_version_map_vector is a vector.
4316 (resolve_symbol_ccl_program): Check that vector header is in range.
4317 Always copy the vector, so that we can check its contents reliably
4318 now rather than having to recheck each instruction as it's being
4319 executed. Check that vector words fit in 'int'.
4320 (ccl_get_compiled_code, Fregister_ccl_program)
4321 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
4322 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
4323 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
4324 contents are in range.
4325 (Fccl_execute_on_string): Check that status is in range.
4326 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
4327 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
4328 Accept and return EMACS_INT, not int, because callers can pass values
4329 out of 'int' range.
4330 (c_string_width, strwidth, lisp_string_width, chars_in_text)
4331 (multibyte_chars_in_text, parse_str_as_multibyte)

4334 (string_escape_byte8, Fget_byte):
4335 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4336 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
4337 avoid mishandling large integers.
4338 * character.h: Adjust decls to match defn changes elsewhere.
4339 * charset.c (load_charset_map_from_file, find_charsets_in_text)
4340 (Ffind_charset_region):
4341 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4342 (load_charset_map_from_file): Redo idx calculation to avoid overflow.

4344 Don't assume fixnum fits in int.
4345 (load_charset_map_from_vector, Fmap_charset_chars):

4347 (Fdefine_charset_internal): Check ranges here, more carefully.
4348 Don't rely on undefined behavior with signed left shift overflow.
4349 Don't assume unsigned int fits into fixnum, or that fixnum fits
4350 into unsigned int. Don't require max_code to be a valid fixnum;
4351 that's not true for gb10830 4-byte on a 32-bit host. Allow
4352 invalid_code to be a cons, for the same reason. Require code_offset
4353 to be a character. Avoid int overflow if max_char is close
4354 to INT_MAX.
4355 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
4356 this is intended anyway and avoids some undefined behavior.
4357 (load_charset_map): Pass unsigned, not int, as 2nd arg of
4358 INDEX_TO_CODE_POINT, as that's what it expects.
4359 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
4360 * charset.h (DECODE_CHAR): Return int, not unsigned;
4361 this is what was intended anyway, and it avoids undefined behavior.
4362 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
4363 integer-overflow issues.
4364 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
4365 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
4366 where the argument is EMACS_INT, and this behavior is not intended.
4367 * chartab.c (Fmake_char_table, Fset_char_table_range)
4368 (uniprop_get_decoder, uniprop_get_encoder):
4369 Don't assume fixnum fits in int.
4370 * cmds.c (move_point): New function, that does the gist of
4371 Fforward_char and Fbackward_char, but does so while checking
4372 for integer overflow more accurately.
4373 (Fforward_char, Fbackward_char): Use it.
4374 (Fforward_line, Fend_of_line, internal_self_insert)
4375 (internal_self_insert):
4376 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4377 Fix a FIXME, by checking for integer overflow when calculating
4378 target_clm and actual_clm.

4410 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4411 (consume_chars): Rewrite to not calculate an address outside buffer.

4413 Don't access memory outside of the args array.
4414 (Fdefine_coding_system_internal): Check for charset-id overflow.
4415 (ENCODE_ISO_CHARACTER): Use unsigned, not int, to store the unsigned
4416 result of ENCODE_CHAR.

4435 * data.c (let_shadows_buffer_binding_p, let_shadows_global_binding_p):
4436 Do not attempt to compute the address of the object just before a
4437 buffer; this is not portable.
4438 (Faref, Faset):
4439 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4440 (Faset): Use int, not EMACS_INT, where int is wide enough.

5194 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
5195 and right-margin display specs even if the spec is invalid or we
5196 are on a TTY, and thus unable to display on the fringes.
5197 That's because the text with the property will not be displayed anyway,
5198 so we need to signal to the caller that this is a "replacing"
5199 display spec. This fixes display when the spec is invalid or we
5200 are on a TTY.
5202 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
5204 * unexaix.c (make_hdr): Fix typo in prototype.
5205 This bug broke the build on AIX. Problem reported by Gilles Pion.
5207 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
5209 * keyboard.c (kbd_buffer_get_event): Read special events also in
5210 batch mode. (Bug#11415)
5212 2012-05-12 Glenn Morris <rgm@gnu.org>
5214 * ns.mk: Update for ns_appbindir no longer having trailing "/".
5216 2012-05-12 Eli Zaretskii <eliz@gnu.org>
5218 * lisp.mk (lisp): Add newcomment.elc.
5220 2012-05-12 Glenn Morris <rgm@gnu.org>
5222 * Makefile.in (MKDIR_P): New, set by configure.
5223 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
5225 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
5227 Remove unused function hourglass_started.
5228 * dispextern.h (hourglass_started):
5229 * w32fns.c (hourglass_started):
5230 * xdisp.c (hourglass_started): Remove.
5232 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
5234 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
5235 Update dependencies.
5237 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
5239 * xgselect.c (xg_select): Put maxfds+1 into a var.
5240 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
5242 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
5244 2012-05-10 Dave Abrahams <dave@boostpro.com>
5246 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
5247 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
5249 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
5251 * dbusbind.c (xd_registered_buses): New internal Lisp object.
5252 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
5253 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
5254 Initialize xd_registered_buses.
5256 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
5258 Untag more efficiently if USE_LSB_TAG.
5259 This is based on a proposal by YAMAMOTO Mitsuharu in
5260 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
5261 For an admittedly artificial (nth 8000 longlist) benchmark on
5262 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
5263 Emacs's overall text size by 1%.
5264 * lisp.h (XUNTAG): New macro.
5265 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
5266 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
5267 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
5268 * eval.c (Fautoload):
5269 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
5270 * frame.h (XFRAME): Use XUNTAG.
5272 Port recent dbusbind.c changes to 32-bit --with-wide-int.
5273 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
5274 Remove unportable assumptions about print widths of types like
5275 dbus_uint32_t.
5276 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
5277 intptr_t when converting between pointer and integer, to avoid GCC
5278 warnings about wrong width.
5280 2012-05-09 Eli Zaretskii <eliz@gnu.org>
5282 * w32proc.c (new_child): Force Windows to reserve only 64KB of
5283 stack for each reader_thread, instead of defaulting to 8MB
5284 determined by the linker. This avoids failures in creating
5285 subprocesses on Windows 7, see the discussion in this thread:
5286 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
5288 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
5290 Fix up display of the *Minibuf-0* buffer in the mini window.
5291 * keyboard.c (read_char): Don't clear the echo area if there's no
5292 message to clear.
5293 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
5294 contents of *Minibuf-0*) if there's no message displayed in its stead.
5296 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
5298 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
5299 batch mode.
5301 2012-05-06 Chong Yidong <cyd@gnu.org>
5303 * lisp.mk (lisp): Update.
5305 2012-05-05 Jim Meyering <meyering@redhat.com>
5307 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
5309 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
5311 * data.c (PUT_ERROR): New macro.
5312 (syms_of_data): Use it. Add new error type `user-error'.
5313 * undo.c (user_error): New function.
5314 (Fprimitive_undo): Use it.
5315 * print.c (print_error_message): Adjust print style for `user-error'.
5316 * keyboard.c (user_error): New function.
5317 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
5319 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
5321 Do not limit current-time-string to years 1000..9999.
5322 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
5323 (Fcurrent_time_string): Support any year that is supported by the
5324 underlying localtime representation. Don't use asctime, as it
5325 has undefined behavior for years outside the range -999..9999.
5327 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
5329 Fix race conditions involving setenv, gmtime, localtime, asctime.
5330 Without this fix, interrupts could mess up code that uses these
5331 nonreentrant functions, since setting TZ invalidates existing
5332 tm_zone or tzname values, and since most of these functions return
5333 pointers to static storage.
5334 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
5335 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
5336 Grow the critical sections to include not just invoking
5337 localtime/gmtime, but also accessing these functions' results
5338 including their tm_zone values if any, and any related TZ setting.
5339 (format_time_string): Last arg is now struct tm *, not struct tm **,
5340 so that the struct tm is saved in the critical section.
5341 All callers changed. Simplify allocation of initial buffer, partly
5342 motivated by the fact that memory allocation needs to be outside
5343 the critical section.
5345 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
5347 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
5348 with RESET_INTERVAL.
5350 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
5351 Remove duplicated buffer name initialization.
5353 2012-05-02 Jim Meyering <jim@meyering.net>
5355 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
5357 * xfns.c (x_window): Use xstrdup (Bug#11375).
5359 2012-05-02 Eli Zaretskii <eliz@gnu.org>
5361 * xdisp.c (pos_visible_p): If already at a newline from the
5362 display string before the 'while' loop, don't walk back the glyphs
5363 from it3.glyph_row. Solves assertion violation when the display
5364 string begins with a newline (egg.el). (Bug#11367)
5366 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
5368 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
5369 Move to simple.el.
5371 2012-05-01 Glenn Morris <rgm@gnu.org>
5373 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
5374 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
5375 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
5376 All were removed before 23.1.
5378 * dispnew.c: Remove HAVE_LIBNCURSES test;
5379 it is always true on relevant platforms.
5381 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
5382 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
5384 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
5386 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
5388 * .gdbinit (xpr): Remove checks for no longer existing misc types.
5389 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
5390 Remove.
5392 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
5394 Do not avoid creating empty evaporating overlays (Bug#9642).
5395 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
5396 That is, do not delete an evaporating overlay if it becomes
5397 empty after its bounds are adjusted to fit within its buffer.
5398 This fix caused other problems, and I'm reverting it until we get
5399 to the bottom of them.
5401 2012-04-27 Chong Yidong <cyd@gnu.org>
5403 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
5405 2012-04-27 Eli Zaretskii <eliz@gnu.org>
5407 * xdisp.c (pos_visible_p): If the window start position is beyond
5408 ZV, start the display from buffer beginning. Prevents assertion
5409 violation in init_iterator when the minibuffer window is scrolled
5410 via the scroll bar.
5412 * window.c (window_scroll_pixel_based): Likewise.
5414 2012-04-27 Chong Yidong <cyd@gnu.org>
5416 * keymap.c (where_is_internal): Doc fix (Bug#10872).
5418 2012-04-27 Glenn Morris <rgm@gnu.org>
5420 * fileio.c (Fcopy_file, Fset_file_selinux_context):
5421 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
5423 2012-04-27 Eli Zaretskii <eliz@gnu.org>
5425 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
5426 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
5428 2012-04-26 Eli Zaretskii <eliz@gnu.org>
5430 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
5431 display element, check also the underlying string or buffer
5432 character. (Bug#11341)
5434 * w32menu.c: Include w32heap.h.
5435 (add_menu_item): If the call to AppendMenuW (via
5436 unicode_append_menu) fails, disable Unicode menus only if we are
5437 running on Windows 9X/Me.
5439 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
5441 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
5442 (xgetint): Add missing shift for LSB tags.
5444 2012-04-24 Martin Rudalics <rudalics@gmx.at>
5446 * keyboard.c (read_char): Don't wipe echo area for select window
5447 events: These might get delayed via `mouse-autoselect-window'
5448 (Bug#11304).
5450 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
5452 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
5453 manipulation of :loaded-from data.
5455 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
5457 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
5458 now a cons (bug#11311).
5460 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
5462 Do not create empty overlays with the evaporate property (Bug#9642).
5463 * buffer.c (Fmove_overlay): Delete an evaporating overlay
5464 if it becomes empty after its bounds are adjusted to fit within
5465 its buffer. Without this fix, in a nonempty buffer (let ((o
5466 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
5467 yields an empty overlay that has the evaporate property, which is
5468 not supposed to happen.
5470 Fix minor GTK3 problems found by static checking.
5471 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
5472 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
5473 (struct _EmacsFixedClass, emacs_fixed_get_type):
5474 Move decls here from emacsgtkfixed.h, since they needn't be public.
5475 (emacs_fixed_get_type): Now static.
5476 (emacs_fixed_class_init): Omit unused local.
5477 (emacs_fixed_child_type): Remove; unused.
5478 * emacsgtkfixed.h (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
5479 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
5480 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
5481 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
5482 (EMACS_FIXED_GET_CLASS): Remove; unused.
5483 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
5485 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
5486 Problem reported by Juanma Barranquero for Windows -Wunused-function.
5488 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
5490 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
5491 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
5492 (__malloc_size_t, __malloc_ptrdiff_t):
5493 Remove. All uses removed, replaced by the definiens if needed,
5494 since we can assume C89 or better now.
5495 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
5496 (protect_malloc_state, align, get_contiguous_space)
5497 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)
5498 (malloc_atfork_handler_child, malloc_enable_thread)

5501 (_free, _realloc, _free_internal_nolock, _free_internal, free, cfree)
5502 (special_realloc, _realloc_internal_nolock, _realloc_internal)
5503 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
5504 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
5505 Define using prototypes, not old style.
5506 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
5507 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
5508 (align): Don't assume that signed integer overflow wraps around.
5509 Omit unused local var.
5510 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
5511 (_free_internal_nolock, memalign, mallochook, reallochook):
5512 Omit no-longer-needed casts.
5513 (valloc): Use getpagesize, not __getpagesize.
5514 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
5515 (struct hdr): The 'magic' member is now size_t, not unsigned long.
5517 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
5519 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
5521 Move functions from C to Lisp. Make non-blocking method calls
5522 the default. Implement further D-Bus standard interfaces.

5553 (Fdbus_send_signal, Fdbus_register_service)
5554 (Fdbus_register_signal, Fdbus_register_method): Move to dbus.el.
5555 (xd_read_message_1): Obey new structure of Vdbus_registered_objects.
5556 (xd_read_queued_messages): Obey new structure of Vdbus_registered_buses.
5557 (Vdbus_compiled_version, Vdbus_runtime_version)
5558 (Vdbus_message_type_invalid, Vdbus_message_type_method_call)

5564 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
5566 Fix GC_MALLOC_CHECK debugging output on 64-bit hosts.
5567 * alloc.c (emacs_blocked_malloc) [GC_MALLOC_CHECK]:
5568 Do not assume ptrdiff_t is the same width as 'int'.
5570 * alloc.c: Handle unusual debugging option combinations.
5571 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
5572 since the two debugging options are incompatible.
5573 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
5574 is defined.
5575 (mem_init, mem_insert, mem_insert_fixup):
5576 Define if GC_MARK_STACK || GC_MALLOC_CHECK.
5577 (NEED_MEM_INSERT): Remove; no longer needed.
5579 2012-04-22 Leo Liu <sdl.web@gmail.com>
5581 * sysdep.c (list_system_processes): Support Darwin (Bug#5725).
5583 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
5585 * sysdep.c [__FreeBSD__]: Minor cleanups.
5586 (list_system_processes, system_process_attributes) [__FreeBSD__]:
5587 Use Emacs indenting style more consistently. Avoid some casts.
5588 Use 'double' consistently rather than mixing 'float' and 'double'.
5590 2012-04-21 Eduard Wiebe <usenet@pusto.de>
5592 * sysdep.c (list_system_processes, system_process_attributes):
5593 Add implementation for FreeBSD (Bug#5243).
5595 2012-04-21 Andreas Schwab <schwab@linux-m68k.org>
5597 * lisp.mk (lisp): Update.
5599 2012-04-20 Paul Eggert <eggert@cs.ucla.edu>

5607 is nil.
5608 (print_object): Check for cycles even when print-circle is nil and

5611 2012-04-20 Chong Yidong <cyd@gnu.org>
5613 * process.c (wait_reading_process_output): If EIO occurs on a pty,
5614 set the status to "failed" and ensure that sentinel is run.

5618 * process.c (Fset_process_inherit_coding_system_flag)
5619 (Fset_process_query_on_exit_flag): Doc fix (mention return value).
5620 (Fmake_network_process, Fmake_serial_process): Doc fix.
5622 2012-04-20 Eli Zaretskii <eliz@gnu.org>
5624 * xdisp.c (string_buffer_position_lim): Limit starting position to
5625 BEGV.
5626 (set_cursor_from_row): If called for a mode-line or header-line
5627 row, return zero immediately.
5628 (try_cursor_movement): If inside continuation line, don't back up
5629 farther than the first row after the header line, if any.
5630 Don't consider the header-line row as "partially visible", even if
5631 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
5633 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
5635 * lread.c (lisp_file_lexically_bound_p): Fix hang at ";-*-\n"

5638 2012-04-20 Teodor Zlatanov <tzz@lifelogs.com>
5639 2012-04-18 Paul Eggert <eggert@cs.ucla.edu>

5643 (WARN_CFLAGS, WERROR_CFLAGS): New macros.
5644 (ALL_CFLAGS): Use new macros rather than old.
5645 * process.c: Ignore -Wstrict-overflow to work around GCC bug 52904.
5646 * regex.c: Ignore -Wstrict-overflow. If !emacs, also ignore
5647 -Wunused-but-set-variable, -Wunused-function, -Wunused-macros,
5648 -Wunused-result, -Wunused-variable. This should go away once
5649 the Emacs and Gnulib regex code is merged.
5650 (xmalloc, xrealloc): Now static.
5652 2012-04-17 Paul Eggert <eggert@cs.ucla.edu>
5654 * dired.c (Fsystem_groups): Remove unused local.
5656 2012-04-17 Glenn Morris <rgm@gnu.org>

5663 (syms_of_dired): Add them.
5665 2012-04-16 Paul Eggert <eggert@cs.ucla.edu>
5667 Fix minor alloc.c problems found by static checking.
5668 * alloc.c (_malloc_internal, _free_internal) [!DOUG_LEA_MALLOC]:
5669 New extern decls, to avoid calling undeclared functions.
5670 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
5671 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
5672 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
5673 (NEED_MEM_INSERT): New macro.
5674 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
5675 Remove one incorrect comment and fix another.

5680 (r_alloc_size_in_use, r_alloc_freeze, r_alloc_thaw): Remove; unused.
5681 (r_alloc_sbrk): Now static.
5683 Improve ralloc.c interface checking.
5684 See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html
5685 * buffer.c (ralloc_reset_variable, r_alloc, r_re_alloc)
5686 (r_alloc_free) [REL_ALLOC]: Move decls from here ...

5688 [REL_ALLOC]: ... to here, to check interface.
5689 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
5690 Remove decls. This fixes an "It stinks!".
5692 * alloc.c (which_symbols): Fix alignment issue / type clash.
5694 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
5696 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
5697 (struct Lisp_Misc_Any): Likewise.
5698 (struct Lisp_Free): Likewise.
5699 * alloc.c (union aligned_Lisp_Symbol): Define.
5700 (SYMBOL_BLOCK_SIZE, struct symbol_block): Use union

5707 2012-04-14 Paul Eggert <eggert@cs.ucla.edu>
5709 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
5710 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
5711 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
5712 * s/netbsd.h, s/sol2-6.h:
5713 Remove definition of GC_MARK_STACK, since the default now works.
5714 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
5715 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
5716 no longer the default.
5717 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
5719 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
5721 * lread.c (lisp_file_lexically_bound_p):
5722 Fix hang at ";-*-\n" (bug#11238).
5724 2012-04-14 Eli Zaretskii <eliz@gnu.org>
5726 * xdisp.c (find_last_unchanged_at_beg_row): Don't consider a row

5729 2012-04-14 Jan Djärv <jan.h.d@swipnet.se>
5731 * nsterm.m (constrainFrameRect): Always constrain when there is only
5732 one screen (Bug#10962).
5734 2012-04-13 Ken Brown <kbrown@cornell.edu>
5736 * s/cygwin.h (PTY_OPEN): Don't try to close a bogus file descriptor.
5738 2012-04-13 Reuben Thomas <rrt@sc3d.org>
5740 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
5742 2012-04-11 Daniel Colascione <dancol@dancol.org>
5744 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
5745 against is gone. It's better to use vfork now so that when Cygwin
5746 gains a new, working vfork, we use it automatically (bug#10398).
5748 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
5750 * window.c (save_window_save): Obey window-point-insertion-type.
5752 2012-04-11 Glenn Morris <rgm@gnu.org>
5754 * Makefile.in (GNUSTEP_CFLAGS): Rename from C_SWITCH_X_SYSTEM.

5760 2012-04-10 Jason S. Cornez <jcornez@ravenpack.com> (tiny change)
5762 * keyboard.c: Override inhibit-quit after the third C-g (bug#6585).
5763 (force_quit_count): New var.
5764 (handle_interrupt): Use it.
5766 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
5768 * w32.c (w32_delayed_load): Record the full path of the library
5769 being loaded (bug#10424).
5771 2012-04-09 Glenn Morris <rgm@gnu.org>
5773 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
5774 not just in the obarray, before snarfing them. (Bug#11036)
5776 * Makefile.in ($(leimdir)/leim-list.el):
5777 Pass EMACS rather than BUILT_EMACS.
5779 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
5781 * process.c (make_process):
5782 * process.h: Add integer `gnutls_handshakes_tried' member to
5783 process struct.
5785 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
5786 Add convenience `GNUTLS_LOG2i' macro.
5788 * gnutls.c (gnutls_log_function2i): Convenience log function.
5789 (emacs_gnutls_read): Use new log functions,
5790 `gnutls_handshakes_tried' process member, and
5791 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
5792 attempts per process (connection).
5794 2012-04-09 Chong Yidong <cyd@gnu.org>
5796 * eval.c (Fuser_variable_p, user_variable_p_eh)
5797 (lisp_indirect_variable): Functions deleted.
5798 (Fdefvar): Caller changed.
5800 * callint.c (Finteractive, Fcall_interactively):
5801 * minibuf.c (Fread_variable): Callers changed.
5803 2012-04-09 Eli Zaretskii <eliz@gnu.org>
5805 * xdisp.c (set_cursor_from_row): If the display string appears in
5806 the buffer at position that is closer to point than the position
5807 after the display string, display the cursor on the first glyph of
5808 the display string. Fixes cursor display when a 'display' text
5809 property immediately follows invisible text. (Bug#11094)
5811 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
5813 composite.c: use 'double' consistently
5814 * composite.c (get_composition_id): Use 'double' consistently
5815 instead of converting 'float' to 'double' and vice versa; this is
5816 easier to understand and avoids a GCC warning.
5818 2012-04-09 Glenn Morris <rgm@gnu.org>
5820 * Makefile.in: Generate leim-list with bootstrap-emacs, in
5821 preparation for dumping it with emacs. (Bug#4789)
5822 (leimdir): New variable.
5823 ($(leimdir)/leim-list.el): New rule.
5824 (emacs$(EXEEXT)): Depend on leim-list.el.

5828 (init_buffer_once, syms_of_buffer): Remove Qucs_set_table_for_input.
5830 2012-04-08 Andreas Schwab <schwab@linux-m68k.org>
5832 * lisp.h (struct Lisp_Symbol): Add explicit padding to ensure
5833 proper alignment.

5837 * xml.c (init_libxml2_functions) [WINDOWSNT]:
5838 Remove unused local variable.
5840 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
5842 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
5843 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
5844 (mark_memory): Mark Lisp_Objects only if pointers might hide in
5845 objects, as mark_maybe_pointer will catch them otherwise.
5846 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
5847 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
5849 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
5851 Fix typo that broke non-Windows builds.
5852 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.
5854 2012-04-07 Eli Zaretskii <eliz@gnu.org>
5856 Support building on MS-Windows with libxml2.
5858 * makefile.w32-in (OBJ2): Add xml.$(O).
5859 (GLOBAL_SOURCES): Add xml.c.
5860 ($(BLD)/xml.$(O)): New dependency list.
5862 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
5863 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
5864 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
5865 [!WINDOWSNT]: New macros.
5866 (init_libxml2_functions, libxml2_loaded_p): New functions.
5867 (parse_region): Call fn_xmlCheckVersion instead of using the macro
5868 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
5869 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
5870 Calls xmlCleanupParser only if libxml2 was loaded (or statically
5871 linked in).
5872 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
5873 Call init_libxml2_functions before calling libxml2 functions.
5874 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
5876 * emacs.c: Don't include libxml/parser.h.
5877 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
5878 xmlCleanupParser directly.
5880 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
5882 2012-04-07 Eli Zaretskii <eliz@gnu.org>
5884 * indent.c (Fvertical_motion): If there is a display string at
5885 point, use it.vpos to compute how many lines to backtrack after
5886 move_it_to point. (Bug#11133)
5888 2012-04-06 Eli Zaretskii <eliz@gnu.org>
5890 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
5891 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
5892 about subtle differences between FETCH_CHAR* and STRING_CHAR*
5893 macros related to unification of CJK characters. For the details,
5894 see the discussion following the message here:
5895 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
5897 2012-04-04 Chong Yidong <cyd@gnu.org>
5899 * keyboard.c (Vdelayed_warnings_list): Doc fix.
5901 2012-04-01 Eli Zaretskii <eliz@gnu.org>
5903 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
5904 instead of alloca. (Bug#11138)
5906 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
5908 * w32menu.c (is_simple_dialog): Properly check lisp types.
5909 (Bug#11141)
5911 2012-03-31 Eli Zaretskii <eliz@gnu.org>
5913 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
5914 position we get to after a call to move_it_to fails the
5915 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
5916 only if we wind up in a string from display property. (Bug#11063)
5918 * window.c (Fdelete_other_windows_internal): Invalidate the row
5919 and column information about mouse highlight, so that redisplay
5920 restores it after reallocating the glyph matrices. (Bug#7464)
5922 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
5923 string comes from a `display' text property, use the buffer
5924 position of that property as if we actually saw that position in
5925 the row's glyphs.
5926 (move_it_by_lines): Remove the assertion that
5927 "it->current_x == 0 && it->hpos == 0" which can be legitimately
5928 violated when there's a before-string at the beginning of a line.
5929 (Bug#11063)
5931 2012-03-30 Eli Zaretskii <eliz@gnu.org>
5933 * xdisp.c (append_space_for_newline): If the default face was
5934 remapped, use the remapped face for the appended newline.
5935 (extend_face_to_end_of_line): Use the remapped default face for
5936 extending the face to the end of the line.
5937 (display_line): Call extend_face_to_end_of_line when the default
5938 face was remapped. (Bug#11068)
5940 2012-03-29 Eli Zaretskii <eliz@gnu.org>
5942 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
5944 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
5946 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
5948 2012-03-27 Glenn Morris <rgm@gnu.org>
5950 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
5951 Doc fixes.
5953 2012-03-26 Kenichi Handa <handa@m17n.org>
5955 * dispextern.h (struct glyph): Fix previous change. Change the
5956 bit length of glyphless.ch to 25 (Bug#11082).
5958 2012-03-26 Chong Yidong <cyd@gnu.org>
5960 * keyboard.c (Vselection_inhibit_update_commands): New variable.
5961 (command_loop_1): Use it; inhibit selection update for
5962 handle-select-window too (Bug#8996).
5964 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
5966 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
5968 2012-03-25 Kenichi Handa <handa@m17n.org>
5970 * dispextern.h (struct glyph): Change the bit length of
5971 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
5973 2012-03-24 Eli Zaretskii <eliz@gnu.org>
5975 * s/ms-w32.h (tzname): Include time.h before redirecting to
5976 _tzname. Fixes the MSVC build. (Bug#9960)
5978 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
5980 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
5981 characters.
5983 * xterm.c (XTread_socket): Only modify handling_signal if
5984 !SYNC_INPUT. (Bug#11080)
5986 2012-03-23 Eli Zaretskii <eliz@gnu.org>
5988 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
5989 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
5990 when fetching a multibyte character consumes more bytes than
5991 CHAR_BYTES returns, due to unification of CJK characters in
5992 string_char. (Bug#11073)
5994 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
5996 * process.c (wait_reading_process_output): Handle pty disconnect
5997 by refraining from sending oneself a SIGCHLD (bug#10933).
5999 2012-03-22 Chong Yidong <cyd@gnu.org>
6001 * dispextern.h (struct it): New member string_from_prefix_prop_p.
6003 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
6004 Mark string as coming from a prefix property.
6005 (handle_face_prop): Use default face for prefix strings (Bug#4281).
6006 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
6008 2012-03-21 Chong Yidong <cyd@gnu.org>
6010 * xfaces.c (Vface_remapping_alist): Doc fix.
6012 2012-03-20 Eli Zaretskii <eliz@gnu.org>
6014 * w32proc.c (Fw32_set_console_codepage)
6015 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
6016 Doc fixes.
6018 2012-03-20 Chong Yidong <cyd@gnu.org>
6020 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
6021 to reflect default non-nil value of redisplay-dont-pause.
6023 2012-03-19 Kenichi Handa <handa@m17n.org>

6026 it fit in a valid range (Bug#11003).
6028 2012-03-18 Eli Zaretskii <eliz@gnu.org>
6030 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
6031 that is not from display property, accept the row as a "cursor
6032 row" if one of the string's character has a non-nil `cursor'
6033 property. Fixes cursor positioning when there are newlines in
6034 overlay strings, e.g. in icomplete.el. (Bug#11035)
6036 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
6038 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
6040 2012-03-12 Chong Yidong <cyd@gnu.org>
6042 * eval.c (inhibit_lisp_code): Rename from
6043 inhibit_window_configuration_change_hook; move from window.c.
6045 * xfns.c (unwind_create_frame_1, Fx_create_frame):
6046 * window.c (run_window_configuration_change_hook)
6047 (syms_of_window): Callers changed.
6049 2012-03-11 Chong Yidong <cyd@gnu.org>
6051 * keymap.c (Fkey_description): Doc fix (Bug#9700).
6053 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
6055 2012-03-10 Chong Yidong <cyd@gnu.org>
6057 * frame.c (other_visible_frames): Don't assume the selected frame
6058 is visible (Bug#10955).
6060 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
6062 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
6064 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
6066 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
6067 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
6068 zero (Bug#10954).
6070 2012-03-03 Glenn Morris <rgm@gnu.org>
6072 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
6074 2012-03-02 Eli Zaretskii <eliz@gnu.org>
6076 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
6077 position past the first glyph_row that ends at ZV. (Bug#10902)
6078 (redisplay_window, next_element_from_string): Fix typos in
6079 comments.
6080 (redisplay_window): Pass to move_it_vertically the margin in
6081 pixels, not in screen lines.
6083 2012-03-02 Glenn Morris <rgm@gnu.org>
6085 * buffer.c (buffer-list-update-hook): Doc fix.
6087 2012-02-29 Eli Zaretskii <eliz@gnu.org>
6089 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
6090 push_it before setting up the iterator for the first overlay
6091 string, even if we have an empty string loaded.
6092 (next_overlay_string): If there's an empty string on the iterator
6093 stack, pop the stack. (Bug#10903)
6095 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
6097 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
6098 Suggested by Stefan Monnier in
6099 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
6100 * alloc.c (widen_to_Lisp_Object): New static function.
6101 (mark_memory): Also mark Lisp_Objects by fetching pointer words
6102 and widening them to Lisp_Objects. This would work even if
6103 USE_LSB_TAG is defined and wide integers are used, which might
6104 happen in a future version of Emacs.
6106 2012-02-25 Chong Yidong <cyd@gnu.org>
6108 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
6109 Doc fix.

6145 when computing $valmask.
6147 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
6148 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
6149 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
6150 It's useless in that case, and it can cause problems on hosts
6151 that allocate halves of EMACS_INT values separately.
6152 Reported by Dan Horák. Diagnosed by Andreas Schwab in
6153 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
6154 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
6155 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
6156 it avoids undefined behavior on hosts where shifting right by more
6157 than the word width has undefined behavior.
6159 2012-02-19 Chong Yidong <cyd@gnu.org>
6161 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
6162 (Funhandled_file_name_directory, Ffile_name_as_directory)

6204 * window.c (Fdelete_window_internal): Invalidate the mouse
6205 highlight (Bug#9904).

6239 * buffer.c (Fbuffer_local_variables)
6240 (buffer_lisp_local_variables): Handle unbound vars correctly;
6241 don't let Qunbound leak into Lisp.
6243 2012-02-07 Glenn Morris <rgm@gnu.org>
6245 * image.c (Fimagemagick_types): Doc fix.

6283 * character.c (char_width): Return EMACS_INT, not int.
6284 (char_width, c_string_width): Check for overflow when
6285 computing the width; this is possible now that individual
6286 characters can have unbounded width. Problem introduced

6822 (ALIGN_GCTYPEBITS) [_MSC_VER]: Define.
6823 (DECL_ALIGN) [_MSC_VER]: Use it, as MSVC doesn't like bit ops in

6941 is set, removing the need for VIRT_ADDRESS_VARIES.
6942 (PURE_P): Use a more-efficient implementation that needs just one

6949 consistency with the new puresize.h.
6950 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.

6958 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
6959 behave as if the cursor position were at the window margin.
6961 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
6962 and the cursor position is out of bounds, behave as if the cursor
6963 position were at the window margin. (Bug#10075)
6965 2011-11-18 Chong Yidong <cyd@gnu.org>
6967 * window.c (Fwindow_combination_limit): Make first argument

6989 compute_line_metrics.
6990 (compute_line_metrics): Call row_hash, instead of computing the
6991 hash code inline.
6993 * dispnew.c (verify_row_hash): Call row_hash for computing the
6994 hash code of a row, instead of duplicating code from xdisp.c.
6996 * dispextern.h (row_hash): Add prototype.
6998 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>

7049 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
7050 with user-defined heap size. Bump the default size of the temacs
7051 heap to 27MB, to avoid memory warning when running temacs.

7173 * xmenu.c (cleanup_widget_value_tree): New function.
7174 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of

7181 (window_box_width, window_box_left, window_box_left_offset)
7182 (window_box_right, window_box_right_offset): Declare extern.
7183 Otherwise, these inline functions do not conform to C99 and
7184 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
7185 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
7186 * intervals.c (adjust_intervals_for_insertion)

7189 (static_offset_intervals): Remove.
7190 (offset_intervals): Rewrite using the old contents of
7191 static_offset_intervals. The old version didn't conform to C99

7214 (Fwindow_margins, Fwindow_fringes, Fwindow_scroll_bars)
7215 (Fwindow_vscroll): Doc fix.
7216 (Fwindow_top_child, Fwindow_left_child): Eliminate a nil default

7254 (x_destroy_window): Move code to x_free_frame_resources.
7256 * xfns.c (unwind_create_frame): Fix comment.

7264 Support MSVC build with newer versions of Visual Studio.
7265 * makefile.w32-in (TAGS-gmake): Don't use $(patsubst ...), as

7329 Rename cover_string to disp_string.
7331 2011-11-01 Martin Rudalics <rudalics@gmx.at>

7505 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
7506 * editfns.c: Rewrite current-time-zone so that it invokes
7507 the equivalent of (format-time-string "%Z") to get the time zone name.
7508 This fixes a bug when the time zone name contains characters that
7509 need converting from the system time locale to Emacs internal format.
7510 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
7511 that patch fixed format-time-string to do the conversion, but
7512 I forgot to fix current-time-zone.
7513 (format_time_string): New function, containing most of
7514 what Fformat_time_string used to contain.
7515 (Fformat_time_string): Rewrite in terms of format_time_string.

7519 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
7520 Jason Rumney's 2007-06-07 change worked around this bug, but
7521 didn't fix it.
7522 * systime.h (tzname, timezone): Remove no-longer-used declarations.
7524 2011-10-19 Eli Zaretskii <eliz@gnu.org>
7526 * xdisp.c (start_display): If the character at POS is displayed
7527 via a display vector, reset IT->current.dpvec_index to zero.
7528 (try_window_reusing_current_matrix): If a line ends in a display
7529 vector or the next line starts in a display vector, continue
7530 redrawing the window even though the character position of
7531 start_row was reached.
7532 (Bug#9771, part 2)
7534 2011-10-18 Chong Yidong <cyd@gnu.org>
7536 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
7537 with nobreak-char-display too.
7539 2011-10-18 Eli Zaretskii <eliz@gnu.org>
7541 Fix part 3 of bug#9771.
7542 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
7543 (bidi_resolve_neutral): Don't enter the expensive loop looking for
7544 non-neutral characters if the current character is a paragraph
7545 separator (a.k.a. Newline). This avoids running the same
7546 expensive loop twice, once when we consume the preceding newline
7547 and the other time when the line actually needs to be displayed.
7548 Avoid the loop when we see neutrals on the base embedding level
7549 following a character whose directionality is the same as the
7550 paragraph's. This avoids running the expensive loop when a line
7551 ends in a long sequence of neutrals, like control characters.
7552 Add assertion against STRONG_AL type. Slightly rearrange code
7553 that determines the type of a neutral given the first non-neutral
7554 that follows it.
7555 (bidi_level_of_next_char): Set next_en_pos to zero when
7556 invalidating its info.
7558 2011-10-17 Eli Zaretskii <eliz@gnu.org>
7560 * xdisp.c (push_display_prop): Determine whether to record string
7561 or buffer position by IT->string, not by IT->method. Allow
7562 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
7563 (move_it_vertically_backward): Don't look for character position
7564 immediately after the newline when in a continuation line.
7565 (Bug#9771, part 1)
7567 2011-10-15 Martin Rudalics <rudalics@gmx.at>
7569 * window.c (coordinates_in_window): Rewrite and delabelize
7570 vertical border check. (Bug#5357) (Bug#9618)
7572 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
7574 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
7575 errors in XSetWindowBorder (bug#9310).
7577 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
7579 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
7580 avoid crash when xmalloc overrun checking is enabled.
7582 2011-10-13 Eli Zaretskii <eliz@gnu.org>
7584 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
7585 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
7586 cursor motion with <left> and <right> arrow keys.
7588 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
7589 some callers set that themselves.
7591 2011-10-12 Eli Zaretskii <eliz@gnu.org>
7593 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
7594 display string and the previous row comes from the same string and
7595 is empty. (Bug#9739) (Bug#9738)
7597 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
7599 * doc.c (get_doc_string): Encode file name (bug#9735).
7601 2011-10-12 Eli Zaretskii <eliz@gnu.org>
7603 * bidi.c (bidi_level_of_next_char):
7604 * xdisp.c (get_visually_first_element): Remove old incorrect
7605 comments regarding the Unicode Line Separator character.
7607 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
7609 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
7611 * alloc.c (Fgc_status): Do not access beyond zombies array
7612 boundary if nzombies > MAX_ZOMBIES.
7613 * alloc.c (dump_zombies): Add missing format specifier.
7615 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
7617 * xdisp.c (set_cursor_from_row): Simplify conditionals,
7618 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
7620 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
7621 Some packages use them to denote characters with modifiers.
7623 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
7625 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
7626 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
7627 matching a pp-number. Rename parameter var to var1.
7629 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
7631 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
7633 2011-10-08 Glenn Morris <rgm@gnu.org>
7635 * callint.c (Fcall_interactively): Give a more explicit error for the
7636 'c' case with a non-character input. (Bug#8479)
7638 2011-10-08 Eli Zaretskii <eliz@gnu.org>
7640 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
7641 lines.
7642 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
7643 lines that are hscrolled on the left.
7645 * dispnew.c (buffer_posn_from_coords): Account for a possible
7646 presence of header-line. (Bug#4426)
7648 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
7650 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
7651 Don't advertise functionality which we discourage or doesn't work.
7653 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
7655 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
7656 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
7657 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
7658 this makes Emacs dump core during garbage collection on rare
7659 occasions. sizeof is obviously inferior to offsetof here, so
7660 stick with offsetof.
7661 (GC_POINTER_ALIGNMENT): New macro.
7662 (mark_memory): Omit 3rd (offset) arg; caller changed.
7663 Don't assume EMACS_INT alignment is the same as pointer alignment.
7665 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
7667 * keyboard.c (read_key_sequence_remapped): New var.
7668 (read_key_sequence): Compute remapping in the right buffer.
7669 (command_loop_1): Use read_key_sequence's remapping directly.
7671 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
7673 * dired.c (file_name_completion): Don't expand file name.
7674 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
7675 before checking file name handler.
7677 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
7678 they've been requested explicitly (bug#9591).
7680 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
7682 * keymap.c (Fsingle_key_description): Use make_specified_string
7683 instead of build_string to build string from push_key_description.
7684 (Bug#5193)
7686 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
7688 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
7689 This fixes a Y2038 bug on 64-bit hosts.
7690 * buffer.c (reset_buffer):
7691 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
7692 (Fclear_buffer_auto_save_failure):
7693 Use 0, not -1, to represent an unset failure time, since time_t
7694 might not be signed.
7696 Remove dependency on glibc malloc internals.
7697 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7698 Move back here from lisp.h, but with their new implementations.
7699 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7700 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
7701 * charset.c (charset_table_init): New static var.
7702 (syms_of_charset): Use it instead of xmalloc. This removes a
7703 dependency on glibc malloc internals. See Eli Zaretskii's comment in
7704 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
7705 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7706 Move back to alloc.c.
7707 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7708 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
7710 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
7712 * nsterm.m (windowDidResize): Call x_set_window_size only when
7713 ns_in_resize is true. Otherwise set pixelwidth/height and
7714 call change_frame_size (Bug#9628).
7716 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
7718 Port --enable-checking=all to Fedora 14 x86-64.
7719 * charset.c (syms_of_charset): Also account for glibc malloc's
7720 internal overhead when calculating the initial malloc maximum.
7722 Port --enable-checking=all to Fedora 14 x86.
7723 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7724 Move to lisp.h.
7725 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
7726 (overrun_check_realloc, overrun_check_free):
7727 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
7728 That way, xmalloc returns a properly-aligned pointer even if
7729 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
7730 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
7731 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
7732 into account when calculating the initial malloc maximum.
7733 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7734 Move here from alloc.c, so that charset.c can use it too.
7735 Properly align; the old code wasn't right for common 32-bit hosts
7736 when configured with --enable-checking=all.
7737 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7738 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
7740 2011-09-29 Eli Zaretskii <eliz@gnu.org>
7742 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
7743 use EDOM.
7745 2011-09-28 Eli Zaretskii <eliz@gnu.org>
7747 * xdisp.c (compute_display_string_end): If there's no display
7748 string at CHARPOS, return -1.
7750 * bidi.c (bidi_fetch_char): When compute_display_string_end
7751 returns a negative value, treat the character as a normal
7752 character not covered by a display string. (Bug#9624)
7754 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
7756 * lread.c (Fread_from_string): Fix typo in docstring.
7758 2011-09-27 Eli Zaretskii <eliz@gnu.org>
7760 * xdisp.c (handle_invisible_prop): If invisible text ends on a
7761 newline, reseat the iterator instead of bidi-iterating there one
7762 character at a time. (Bug#9610)
7763 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
7764 TO_CHARPOS if the bidi iterator is at base embedding level.
7766 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
7768 * lread.c (readevalloop): Use correct code for NBSP.
7769 (read1): Likewise. (Bug#9608)
7771 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
7773 * dbusbind.c (Fdbus_register_signal): When service is not
7774 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
7776 2011-09-25 Glenn Morris <rgm@gnu.org>
7778 * buffer.c (truncate-lines): Doc fix.
7780 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
7782 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
7783 (Fset_window_next_buffers): Doc fix.
7785 2011-09-24 Glenn Morris <rgm@gnu.org>
7787 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
7789 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
7791 Fix minor problems found by static checking.
7792 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
7793 * indent.c (Fvertical_motion): Fix == vs = typo.
7795 2011-09-24 Eli Zaretskii <eliz@gnu.org>
7797 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
7798 Default value is now t. Doc fix.
7800 * indent.c (Fvertical_motion): Compute and apply the overshoot
7801 logic when moving up, not only when moving down. Fix the
7802 confusing name and values of the it_overshoot_expected variable;
7803 logic changes accordingly. (Bug#9254) (Bug#9549)
7805 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
7806 CHARPOS is covered by a display string which includes newlines.
7807 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
7808 is covered by a display string with embedded newlines.
7810 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
7812 * dbusbind.c (Fdbus_register_signal): Add match rule to
7813 Vdbus_registered_objects_table. (Bug#9581)
7814 (Fdbus_register_method, Vdbus_registered_objects_table):
7815 Fix docstring.
7817 2011-09-24 Jim Meyering <meyering@redhat.com>
7819 do not ignore write error for any output size
7820 The previous change was incomplete.
7821 While it makes emacs --batch detect the vast majority of stdout
7822 write failures, errors were still ignored whenever the output size is
7823 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
7824 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
7825 && echo FAIL: ignored write error
7826 FAIL: ignored write error
7827 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
7828 && echo FAIL: ignored write error
7829 FAIL: ignored write error
7830 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
7832 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
7834 * emacs.c (Fkill_emacs): In noninteractive mode exit
7835 non-successfully if a write error occurred on stdout. (Bug#9574)
7837 2011-09-21 Eli Zaretskii <eliz@gnu.org>
7839 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
7840 the xassert test.
7842 * dispextern.h (struct it): Update the comment documenting what
7843 can it->OBJECT be.
7845 2011-09-20 Eli Zaretskii <eliz@gnu.org>
7847 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
7848 a display string, extend search for cursor position to end of row.
7849 (find_row_edges): If the row ends in a newline from a display
7850 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
7851 Handle the case of a display string with multiple newlines.
7852 (Fcurrent_bidi_paragraph_direction): Fix search for previous
7853 non-empty line. Fixes confusing cursor motion with arrow keys at
7854 the beginning of a line that starts with whitespace.
7856 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
7858 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
7859 (bug#9493).
7861 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
7863 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
7864 boolean (Bug#9154).
7866 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7868 * xdisp.c (display_line): Record maximum and minimum buffer
7869 positions even if no glyphs were produced (e.g., by a zero-width
7870 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
7871 buffer positions that will be removed from the glyph row because
7872 they don't fit.
7873 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
7874 column is beyond frame width: don't subtract 1 "pixel" when
7875 computing width of the stretch.
7876 (reseat_at_next_visible_line_start): Undo the change made on
7877 2011-09-17 that saved paragraph information and restored it after
7878 the call to `reseat'. (Bug#9545)
7880 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
7882 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
7883 and turn window cursor on if cleared (Bug#9415).
7885 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
7887 * search.c (boyer_moore): Take unibyte characters from pattern
7888 literally. (Bug#9458)
7890 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7892 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
7894 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
7896 Fix minor problem found by static checking.
7897 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
7898 initialized, to pacify gcc -Wuninitialized.
7900 * fileio.c: Report proper errno when syscall falls.
7901 (Finsert_file_contents): Save and restore errno,
7902 so that report_file_error outputs the correct diagnostic.
7903 (Fwrite_region) [CLASH_DETECTION]: Likewise.
7905 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7907 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
7909 2011-09-17 Eli Zaretskii <eliz@gnu.org>
7911 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
7912 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
7914 2011-09-17 Eli Zaretskii <eliz@gnu.org>
7916 * xdisp.c (reseat_at_next_visible_line_start): Keep information
7917 about the current paragraph and restore it after the call to reseat.
7919 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
7920 (bidi_find_paragraph_start): Search back for paragraph beginning
7921 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
7922 (bidi_move_to_visually_next): Only trigger paragraph-related
7923 computations when the last character is a newline or at EOB, not
7924 just any NEUTRAL_B. (Bug#9470)
7926 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
7927 truncated lines if point is covered by a display string. (Bug#9524)
7929 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
7931 * xselect.c: Relax test for outgoing X longs (Bug#9498).
7932 (cons_to_x_long): New function.
7933 (lisp_data_to_selection_data): Use it. Correct the test for
7934 short-versus-long data; it was negated. Break out of vector
7935 loop, for efficiency, when a long datum is discovered.
7937 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
7939 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
7941 2011-09-16 Eli Zaretskii <eliz@gnu.org>
7943 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
7944 GCC PR/17406) by declaring this function with external scope.
7946 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
7948 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
7949 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
7951 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
7953 * editfns.c (Fformat): Correctly handle text properties on "%%".
7955 2011-09-15 Eli Zaretskii <eliz@gnu.org>
7957 * xterm.c (x_draw_composite_glyph_string_foreground):
7958 * w32term.c (x_draw_composite_glyph_string_foreground):
7959 * term.c (encode_terminal_code):
7960 * composite.c (composition_update_it, get_composition_id):
7961 * xdisp.c (get_next_display_element)
7962 (fill_composite_glyph_string): Add comments about special meaning
7963 of TAB characters in a composition.
7965 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
7967 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
7968 This occurs when processing a multibyte format.
7969 Problem reported by Wolfgang Jenker.
7971 2011-09-15 Johan Bockgård <bojohan@gnu.org>
7973 * xdisp.c (try_cursor_movement): Only check for exact match if
7974 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
7976 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7978 Remove unused external symbols.
7979 * dispextern.h (calc_pixel_width_or_height): Remove decl.
7980 * xdisp.c (calc_pixel_width_or_height): Now static.
7981 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
7982 * indent.c (check_display_width):
7983 * w32term.c: Fix comment to match code.
7984 * xterm.c, xterm.h (x_catching_errors): Remove.
7986 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7988 * xselect.c: Use signed conversions more consistently (Bug#9498).
7989 (selection_data_to_lisp_data): Assume incoming selection data are
7990 signed integers, not unsigned. This is to be consistent with
7991 outgoing selection data, which was modified to use signed integers
7992 in as part of the fix to Bug#9196 in response to Jan D.'s comment
7993 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
7994 expects long, not unsigned long.
7996 2011-09-14 Eli Zaretskii <eliz@gnu.org>
7998 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
7999 computation of loop end. Reported by Johan Bockgård
8000 <bojohan@gnu.org>.
8002 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
8004 * frame.c (Fother_visible_frames_p): Function deleted.
8006 2011-09-12 Eli Zaretskii <eliz@gnu.org>
8008 * indent.c (compute_motion): Process display vector front to back
8009 rather than the other way around. (Bug#2496)
8011 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
8013 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
8015 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
8017 * minibuf.c (Fread_from_minibuffer): Doc fix.
8019 2011-09-11 Eli Zaretskii <eliz@gnu.org>
8021 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
8022 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
8024 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
8026 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
8027 value for non-existent files.
8029 2011-09-11 Eli Zaretskii <eliz@gnu.org>
8031 * fileio.c (Finsert_file_contents): If the file cannot be opened,
8032 set its "size" to -1. This will set the modtime_size field of
8033 the corresponding buffer to -1, which is what
8034 verify-visited-file-modtime expects for files that do not exist.
8035 (Bug#9139)
8037 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
8039 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
8040 here ...
8041 * lisp.h: ... from here. push_key_description is no longer
8042 defined in keyboard.c, so its declaration should not be in
8043 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
8044 logically belongs with push_key_description.
8046 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
8048 * buffer.h: Include <sys/types.h> instead of <time.h>.
8049 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
8050 Problem reported by Herbert J. Skuhra.
8052 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
8054 * xml.c (parse_region): Make the parsing work for
8055 non-comment-starting XML files again (bug#9144).
8057 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
8059 * image.c (gif_load): Fix calculation of bottom and right corner.
8060 (Bug#9468)
8062 2011-09-10 Eli Zaretskii <eliz@gnu.org>
8064 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
8065 redisplay in small windows.
8067 2011-09-09 Eli Zaretskii <eliz@gnu.org>
8069 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
8071 2011-09-08 Martin Rudalics <rudalics@gmx.at>
8073 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
8074 Operate on live windows only.
8076 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
8078 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
8080 2011-09-07 Eli Zaretskii <eliz@gnu.org>
8082 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
8083 only under bidi iteration.
8085 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
8087 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
8089 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
8091 isnan: Fix porting problem to Solaris 10 with bundled gcc.
8092 Without this fix, the command to link temacs failed due to an
8093 undefined symbol __builtin_isnan. This is because
8094 /usr/include/iso/math_c99.h #defines isnan(x) to
8095 __builtin_isnan(x), but the bundled gcc, which identifies itself
8096 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
8097 a __builtin_isnan.
8098 * floatfns.c (isnan): #undef, and then #define to a clone of
8099 what's in data.c.
8100 (Fisnan): Always define, since it's always available now.
8101 (syms_of_floatfns): Always define isnan at the Lisp level.
8103 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
8105 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
8107 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
8109 * fileio.c: Fix bugs with large file offsets (Bug#9428).
8110 The previous code assumed that file offsets (off_t values) fit in
8111 EMACS_INT variables, which is not true on typical 32-bit hosts.
8112 The code messed up by falsely reporting buffer overflow in cases
8113 such as (insert-file-contents "big" nil 1 2) into an empty buffer
8114 when "big" contains more than 2**29 bytes, even though this
8115 inserts just one byte and does not overflow the buffer.
8116 (Finsert_file_contents): Store file offsets as off_t
8117 values, not as EMACS_INT values. Check for overflow when
8118 converting between EMACS_INT and off_t. When checking for
8119 buffer overflow or for overlap, take the offsets into account.
8120 Don't use EMACS_INT for small values where int suffices.
8121 When checking for overlap, fix a typo: ZV was used where
8122 ZV_BYTE was intended.
8123 (Fwrite_region): Don't assume off_t fits into 'long'.
8124 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
8126 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
8128 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
8130 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
8132 sprintf-related integer and memory overflow issues (Bug#9412).
8134 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
8135 (esprintf, exprintf, evxprintf): New functions.
8136 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
8137 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
8138 (modify_event_symbol): Do not assume that the length of
8139 name_alist_or_stem is safe to alloca and fits in int.
8140 (Fexecute_extended_command): Likewise for function name and binding.
8141 (Frecursion_depth): Wrap around reliably on integer overflow.
8142 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
8143 since some callers pass EMACS_INT values.
8144 (Fsingle_key_description): Don't crash if symbol name contains more
8145 than MAX_ALLOCA bytes.
8146 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
8147 (get_minibuffer): Arg is now EMACS_INT, not int.
8148 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
8149 (esprintf, exprintf, evxprintf): New decls.
8150 * window.h (command_loop_level, minibuf_level): Reflect API changes.
8152 * dbusbind.c (signature_cat): New function.
8153 (xd_signature, Fdbus_register_signal):
8154 Do not overrun buffer; instead, report string overflow.
8156 * dispnew.c (add_window_display_history): Don't overrun buffer.
8157 Truncate instead; this is OK since it's just a log.
8159 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
8160 even if the time zone offset is outlandishly large.
8161 Don't mishandle offset == INT_MIN.
8163 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
8164 when creating daemon; the previous buffer-overflow check was incorrect.
8166 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
8167 which has the guts of the old verror function.
8169 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
8170 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
8172 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
8173 (font_unparse_xlfd): Don't blindly alloca long strings.
8174 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
8175 fits in int, when using sprintf. Use single snprintf to count
8176 length of string rather than counting it via multiple sprintfs;
8177 that's simpler and more reliable.
8178 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
8179 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
8180 sprintf, in case result does not fit in int.
8182 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
8183 (fontset_from_font): Print it.
8185 * frame.c (tty_frame_count): Now printmax_t, not int.
8186 (make_terminal_frame, set_term_frame_name): Print it.
8187 (x_report_frame_params): In X, window IDs are unsigned long,
8188 not signed long, so print them as unsigned.
8189 (validate_x_resource_name): Check for implausibly long names,
8190 and don't assume name length fits in 'int'.
8191 (x_get_resource_string): Don't blindly alloca invocation name;
8192 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
8193 not fit in int.
8195 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
8196 (xg_check_special_colors, xg_set_geometry):
8197 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
8199 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
8200 Use esprintf, not sprintf, in case result does not fit in int.
8202 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
8203 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
8204 it as a large positive number.
8205 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
8206 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
8208 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
8209 in case result does not fit in int.
8211 * print.c (float_to_string): Detect width overflow more reliably.
8212 (print_object): Make sprintf buffer a bit bigger, to avoid potential
8213 buffer overrun. Don't assume list length fits in 'int'. Treat
8214 print length of 0 as 0, not as infinity; to be consistent with other
8215 uses of print length in this function. Don't overflow print length
8216 index. Don't assume hash table size fits in 'long', or that
8217 vectorlike size fits in 'unsigned long'.
8219 * process.c (make_process): Use printmax_t, not int, to format
8220 process-name gensyms.
8222 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
8224 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
8225 to avoid potential buffer overrun.
8227 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
8228 if X resource line is longer than 512 bytes.
8230 * xfns.c (x_window): Make sprintf buffer a bit bigger
8231 to avoid potential buffer overrun.
8233 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
8235 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
8237 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
8239 Integer overflow fixes for scrolling, etc.
8240 Without these, Emacs silently mishandles large integers sometimes.
8241 For example, "C-u 4294967297 M-x recenter" was treated as if
8242 it were "C-u 1 M-x recenter" on a typical 64-bit host.
8244 * xdisp.c (try_window_id): Check Emacs fixnum range before
8245 converting to 'int'.
8247 * window.c (window_scroll_line_based, Frecenter):
8248 Check that an Emacs fixnum is in range before assigning it to 'int'.
8249 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
8250 values converted from Emacs fixnums.
8251 (Frecenter): Don't wrap around a line count if it is out of 'int'
8252 range; instead, treat it as an extreme value.
8253 (Fset_window_configuration, compare_window_configurations):
8254 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
8256 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
8257 that can exceed INT_MAX. Check that EMACS_INT value is in range
8258 before assigning it to the (possibly-narrower) index.
8259 (match_limit): Don't assume that a fixnum can fit in 'int'.
8261 * print.c (print_object): Use ptrdiff_t, not int, for index that can
8262 exceed INT_MAX.
8264 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
8265 (Fvertical_motion): Don't wrap around LINES values that don't fit
8266 in 'int'. Instead, treat them as extreme values. This is good
8267 enough for windows, which can't have more than INT_MAX lines anyway.
8269 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
8271 * Require libxml/parser.h to avoid compilation warning.
8273 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
8275 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
8276 since this reportedly can destroy thread storage.
8278 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
8280 * syntax.c (find_defun_start): Update all cache variables if
8281 exiting early (Bug#9401).
8283 2011-08-30 Eli Zaretskii <eliz@gnu.org>
8285 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
8287 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
8288 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
8289 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
8291 * term.c (tty_append_glyph): New function.
8292 (produce_stretch_glyph): Static function and its prototype deleted.
8294 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
8295 Add prototypes.
8297 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
8299 * image.c (parse_image_spec): Check for nonnegative, not for positive,
8300 when checking :margin (Bug#9390).
8301 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
8302 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
8303 so that the name doesn't mislead. All uses changed.
8305 2011-08-28 Johan Bockgård <bojohan@gnu.org>
8307 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
8308 set_tty_hooks.
8310 2011-08-27 Eli Zaretskii <eliz@gnu.org>
8312 * xdisp.c (move_it_to): Don't bail out early when reaching
8313 position beyond to_charpos, if we are scanning backwards.
8314 (move_it_vertically_backward): When DY == 0, make sure we get to
8315 the first character in the line after the newline.
8317 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
8319 * ccl.c: Improve and simplify overflow checking (Bug#9196).
8320 (ccl_driver): Do not generate an out-of-range pointer.
8321 (Fccl_execute_on_string): Remove unnecessary check for
8322 integer overflow, noted by Stefan Monnier in
8323 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
8324 Remove a FIXME that didn't need fixing.
8325 Simplify the newly-introduced buffer reallocation code.
8327 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
8329 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
8331 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
8333 Integer and memory overflow issues (Bug#9196).
8335 * doc.c (get_doc_string): Rework so that
8336 get_doc_string_buffer_size is the actual buffer size, rather than
8337 being 1 less than the actual buffer size; this makes xpalloc more
8338 convenient.
8340 * image.c (x_allocate_bitmap_record, cache_image):
8341 * xselect.c (Fx_register_dnd_atom):
8342 Simplify previous changes by using xpalloc.
8344 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
8345 since either will do and ptrdiff_t is convenient with xpalloc.
8347 * charset.c (charset_table_size)
8348 (struct charset_sort_data.priority): Now ptrdiff_t.
8349 (charset_compare): Don't overflow if priorities differ greatly.
8350 (Fsort_charsets): Don't assume list length fits in int.
8351 Check for size-calculation overflow when allocating sort data.
8352 (syms_of_charset): Allocate an initial charset table that is
8353 just under 64 KiB, to avoid problems with glibc malloc and mmap.
8355 * cmds.c (internal_self_insert): Check for size-calculation overflow.
8357 * composite.h (struct composition.glyph_len): Now int, not unsigned.
8358 The actual value is always <= INT_MAX, and leaving it unsigned made
8359 overflow checking harder.
8361 * dispextern.h (struct glyph_matrix.rows_allocated)
8362 (struct face_cache.size): Now ptrdiff_t, for convenience in use
8363 with xpalloc. The values are still always <= INT_MAX.
8365 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
8367 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
8368 (SAFE_NALLOCA): New macro.
8370 * region-cache.c (struct boundary.pos, find_cache_boundary)
8371 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
8372 (set_cache_region, invalidate_region_cache)
8373 (revalidate_region_cache, know_region_cache, region_cache_forward)
8374 (region_cache_backward, pp_cache):
8375 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
8376 so that ptrdiff_t * can be passed to xpalloc.
8377 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
8378 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
8379 (pp_cache): Don't assume cache_len fits in int.
8380 * region-cache.h: Adjust extern decls to match.
8382 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
8383 EMACS_INT, since either will do, for xpalloc.
8385 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
8386 (xnmalloc, xnrealloc, xpalloc): New functions.
8388 * bidi.c (bidi_shelve_header_size): New constant.
8389 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
8390 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
8392 * bidi.c (bidi_cache_shrink):
8393 * buffer.c (overlays_at, overlays_in, record_overlay_string)
8394 (overlay_strings):
8395 Don't update size of array until after memory allocation succeeds,
8396 because xmalloc/xrealloc may not return.
8397 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
8398 now that we have proper integer overflow checking.
8399 (record_overlay_string, overlay_strings): Catch overflows when
8400 calculating size of overlay_str_buf.
8402 * callproc.c (Fcall_process): Check for size overflow when
8403 calculating size of args2.
8404 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
8405 Normally we prefer signed values, but sticking with ptrdiff_t would
8406 require adding more-complicated checks.
8408 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
8409 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
8410 Redo buffer-overflow calculations to avoid integer overflow.
8411 Add a FIXME comment where memory seems to be over-allocated.
8413 * character.c (Fstring): Check for size-calculation overflow.
8415 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
8416 unnecessary integer overflow. Check for size overflow.
8417 (encode_coding_object): Don't update size until xmalloc succeeds.
8419 * composite.c (get_composition_id): Check for overflow in glyph
8420 length calculations.
8422 Integer and memory overflow fixes for display code.
8423 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
8424 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
8425 (scrolling_window): Check for overflow in size calculations.
8426 (line_draw_cost, realloc_glyph_pool, add_row_entry):
8427 Don't assume glyph table len fits in int.
8428 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
8429 (row_table_size): Now ptrdiff_t, not int.
8430 (scrolling_window): Avoid overflow in size calculations.
8431 Don't update size until allocation succeeds.
8432 * fns.c (concat): Check for overflow in size calculations.
8433 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
8434 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
8435 (NEXT_ALMOST_PRIME_LIMIT): New constant.
8437 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
8438 (get_doc_string): Check for size calculation overflow.
8439 Don't update size until allocation succeeds.
8440 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
8441 EMACS_INT, where ptrdiff_t will do.
8442 (Fsubstitute_command_keys): Check for string overflow.
8444 * editfns.c (set_time_zone_rule): Don't assume environment length
8445 fits in int.
8446 (message_length): Now ptrdiff_t, not int.
8447 (Fmessage_box): Don't update size until allocation succeeds.
8448 Don't assume message length fits in int.
8449 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
8451 * emacs.c (main): Do not reallocate argv, since there is a null at
8452 the end that can be overwritten, and this way there's no need to
8453 worry about size-calculation overflow.
8454 (sort_args): Check for size-calculation overflow.
8456 * eval.c (init_eval_once, grow_specpdl): Don't update size until

8462 Check for integer overflow.
8463 (x_set_alpha): Do not assume XINT fits in int.
8465 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
8466 This is for the members text_lines, text_cols, total_lines, total_cols,
8467 where the system imposes an 'int' limit.

8476 Check for size-calculation overflow.
8477 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
8478 do, as we prefer signed integers.
8479 (id_to_widget.max_size, id_to_widget.used)
8480 (xg_store_widget_in_map, xg_remove_widget_from_map)

8532 (Fset_match_data): Don't assume list lengths fit in 'int'.
8534 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
8535 for command line length. Do not attempt to address one before the

8565 (Finternal_make_lisp_face, cache_face):
8566 Check for size calculation overflow.
8567 (cache_face): Treat size calculation overflows as if they were
8568 memory exhaustion (the usual treatment), rather than aborting.
8570 * xfns.c (x_encode_text, x_set_name_internal)
8571 (Fx_change_window_property): Use ptrdiff_t, not int, to count
8572 sizes, since they can exceed INT_MAX in size. Check for size

8576 (xg_select): Check for size calculation overflow.
8577 Don't update size until alloc done.
8579 * xrdb.c (get_environ_db): Don't assume path length fits in int,
8580 as sprintf is limited to int lengths.
8582 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
8583 (X_LONG_MIN): New macros.
8584 Use them to make the following changes clearer.
8585 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
8586 This change doesn't affect the value now, but it may help remind
8587 future maintainers not to raise the value too much later.
8588 (SELECTION_QUANTUM): Remove, replacing with ...
8589 (selection_quantum): ... new function, which avoids overflow.
8590 All uses changed.
8591 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
8592 assumption that selection length fits in 'int'.

8600 Redo calculations to avoid overflow.
8601 (x_reply_selection_request): When sending hint, ceiling it at

8603 something.
8604 (x_get_window_property, receive_incremental_selection)
8605 (lisp_data_to_selection_data, x_property_data_to_lisp):

8609 Don't store size until memory allocation succeeds.
8610 (x_get_window_property): Plug memory leak on memory exhaustion.
8611 Don't double-block input; malloc is safe here. Don't assume 2**34
8612 - 4 fits in unsigned long. Add an xassert to check
8613 XGetWindowProperty overflow. Be more careful about overflow
8614 calculations, and distinguish size from memory overflow better.
8615 (receive_incremental_selection): When tracing, don't assume
8616 unsigned int is less than INT_MAX.
8617 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory

8620 in the range -65535 through -1 fit in an X unsigned short.
8621 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
8622 result parameters unless successful. Rely on cons_to_unsigned
8623 to report problems with elements; the old code wasn't right anyway.
8624 (x_check_property_data): Check for int overflow; we cannot use
8625 a wider type due to X limits.
8626 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
8628 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.

8657 * image.c (xpm_get_color_table_h):
8658 * lisp.h (hash_lookup, hash_put):
8659 * minibuf.c (Ftest_completion):
8660 Use ptrdiff_t for hash table indexes, not int (which is too
8661 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
8662 32-bit --with-wide-int hosts).
8664 * charset.c (Fdefine_charset_internal): Check for integer overflow.
8665 Add a FIXME comment about memory leaks.
8666 (syms_of_charset): Don't assume xmalloc returns.
8668 Don't assume that stated character widths fit in int.

8670 * character.h (CHAR_WIDTH):
8671 * indent.c (MULTIBYTE_BYTES_WIDTH):
8672 Use sanitize_char_width to avoid undefined and/or bad behavior
8673 with outlandish widths.
8674 * character.h (sanitize_tab_width): Rename from sanitize_width,
8675 now that we have two such functions. All uses changed.
8676 (sanitize_char_width): New inline function.
8678 Don't assume that tab-width fits in int.
8679 * character.h (sanitize_width): New inline function.
8680 (SANE_TAB_WIDTH): New macro.

8696 exceed limits imposed by XClientMessageEvent, as well as the usual
8697 ptrdiff_t and size_t limits.
8699 * keyboard.c: Overflow, signedness and related fixes.
8700 (make_lispy_movement): Use same integer type in forward decl
8701 that is used in the definition.
8702 (read_key_sequence, keyremap_step):
8703 Change bufsize argument back to int, undoing my 2011-03-30 change.
8704 We prefer signed types, and int is wide enough here.
8705 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
8706 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
8707 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
8708 length, not size_t. Use ptrdiff_t for index, not int.
8709 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
8710 possibility of integer overflow.
8712 Overflow, signedness and related fixes for images.

8722 * xdisp.c (calc_pixel_width_or_height):
8723 * xfns.c (image_cache_refcount):

8733 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
8734 (lookup_image): Remove unnecessary tests.
8735 (xbm_image_p): Locals are now of int, not EMACS_INT,
8736 since parse_image_check makes sure they fit into int.
8737 (png_load, gif_load, svg_load_image):
8738 Prefer int to unsigned where either will do.
8739 (tiff_handler): New function, combining the cores of the
8740 old tiff_error_handler and tiff_warning_handler.
8741 This function is rewritten to use vsnprintf and thereby avoid
8742 stack buffer overflows. It uses only the features of vsnprintf
8743 that are common to both POSIX and native Microsoft.
8744 (tiff_error_handler, tiff_warning_handler): Use it.
8745 (tiff_load, gif_load, imagemagick_load_image):
8746 Don't assume :index value fits in 'int'.
8747 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
8748 (imagemagick_load_image): Check that crop parameters fit into
8749 the integer types that MagickCropImage accepts. Don't assume
8750 Vimagemagick_render_type has a nonnegative value. Don't assume
8751 size_t fits in 'long'.
8752 (gs_load): Use printmax_t to print the widest integers possible.
8753 Check for integer overflow when computing image height and width.

8762 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
8763 the display spec is of the form `(space ...)'.

8765 handle_single_display_spec, not just 1 or zero.
8766 (handle_single_display_spec): If the display spec is of the form
8767 `(space ...)', and specifies display in the text area, return 2
8768 rather than 1.
8769 (try_cursor_movement): Check for the need to scroll more
8770 accurately, and prefer exact match for point under bidi.
8771 Don't advance `row' beyond the last row of the window.
8773 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
8774 into disp_prop; all users changed.
8776 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns

8789 buffers, return left-to-right.
8790 (set_cursor_from_row): Consider candidate row a win if its glyph
8791 represents a newline and point is on that newline. Fixes cursor
8792 positioning on the newline at EOL of R2L text within L2R
8793 paragraph, and vice versa.
8794 (try_cursor_movement): Check continued rows, in addition to
8795 continuation rows. Fixes unwarranted scroll when point enters a
8796 continued line of R2L text within an L2R paragraph, or vice versa.
8797 (cursor_row_p): Consider the case of point being equal to
8798 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
8799 from the end of a short line to the beginning of a continued line
8800 of R2L text within L2R paragraph.
8801 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for

8824 * xdisp.c (redisplay_window): When computing centering_position,
8825 account for the height of the header line. (Bug#8874)
8827 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
8828 instead of CHAR_TO_BYTE. Fixes a crash when a completion
8829 candidate is selected by the mouse, and that candidate has a
8830 composed character under the mouse.
8832 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
8833 coordinates reported by pos-visible-in-window-p for a composed
8834 character in column zero.

8840 2011-08-22 Eli Zaretskii <eliz@gnu.org>
8842 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
8843 consider it a hit if to_charpos is anywhere in the range of the
8844 composed buffer positions.
8846 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
8848 * image.c (gif_load): Don't assume that each subimage has the same
8849 dimensions as the base image. Handle disposal method that is
8850 "undefined" by the gif spec (Bug#9335).
8852 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
8854 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).

8857 2011-08-19 Eli Zaretskii <eliz@gnu.org>
8859 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
8860 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
8861 from an Org mode buffer to a Speedbar frame.
8863 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
8864 a composition, take its buffer position from IT->cmp_it.charpos.
8865 Fixes cursor positioning at the beginning of a line that begins
8866 with a composed character.
8868 2011-08-18 Eli Zaretskii <eliz@gnu.org>
8870 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
8871 character bidirectional type, use STRONG_L instead. Fixes crashes
8872 in a buffer produced by `describe-categories'.
8874 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
8875 members before the level stack, so they would be saved and
8876 restored when copying iterator state. Fixes incorrect reordering
8877 around TABs covered by display properties.
8879 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
8881 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

8908 (fixup_executable): Force the dumped emacs to reinitialize malloc.
8910 * gmalloc.c [CYGWIN] (bss_sbrk_heapbase, bss_sbrk_heapinfo):
8911 New variables.
8912 (malloc_initialize_1) [CYGWIN]: Prepare for reinitializing the
8913 dumped emacs.
8914 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
8915 in the static heap.
8916 [CYGWIN] (special_realloc): New function.
8917 (_realloc_internal_nolock) [CYGWIN]: Use the new function on
8918 requests to realloc storage in the static heap.
8920 2011-08-15 Paul Eggert <eggert@cs.ucla.edu>
8922 * bidi.c (bidi_initialize): Remove unused local.
8924 2011-08-15 Eli Zaretskii <eliz@gnu.org>
8926 * bidimirror.h:
8927 * biditype.h: Remove file.
8928 * makefile.w32-in ($(BLD)/bidi.$(O)):
8929 * deps.mk (bidi.o): Remove biditype.h and bidimirror.h.
8931 * dispextern.h: Fix a typo in the comment to bidi_type_t.
8933 * chartab.c: Improve commentary for the uniprop_table API.
8935 * bidi.c (bidi_paragraph_init): Support zero value of
8936 bidi_ignore_explicit_marks_for_paragraph_level.
8937 (bidi_initialize): Use uniprop_table instead of including
8938 biditype.h and bidimirror.h.
8940 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
8941 coordinates of the iterator when restoring from ppos_it.
8942 (Bug#9296)
8944 2011-08-14 Kenichi Handa <handa@m17n.org>
8946 * process.c (create_process): Call setup_process_coding_systems
8947 after the pid of the process is set to -1 (Bug#8162).
8949 2011-08-14 Eli Zaretskii <eliz@gnu.org>
8951 * xdisp.c (move_it_in_display_line_to): Don't invoke
8952 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
8953 ppos_it. Fixes vertical cursor motion when line beginning is
8954 covered by an image. (Bug#9296)
8956 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
8958 * nsterm.h (ns_run_ascript): Declare.
8959 (NSAPP_DATA2_RUNASSCRIPT): Define.
8961 * nsfns.m (as_script, as_result, as_status): New static variables.
8962 (ns_run_ascript): New function.
8963 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
8964 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
8965 the event loop. Get status from as_status (Bug#7276).
8967 * nsterm.m (sendEvent): If event is NSApplicationDefined and
8968 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
8969 the event loop (Bug#7276).
8971 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
8973 * gnutls.c (QCgnutls_bootprop_priority)
8974 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
8975 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
8976 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
8977 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
8978 (QCgnutls_bootprop_verify_hostname_error)
8979 (QCgnutls_bootprop_callbacks_verify): Rename from
8980 Qgnutls_bootprop_..., all uses changed.
8982 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
8983 uses changed.
8985 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
8987 * xfaces.c (Qframe_set_background_mode): Now static.
8988 * dispextern.h (Qframe_set_background_mode): Remove decl.
8990 * process.c (Fnetwork_interface_info): Declare local only if needed.
8992 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
8994 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
8995 (Fnetwork_interface_list): Allocate in increments of bytes instead
8996 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
8997 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
8998 sockaddr.
8999 (struct ifflag_def): notrailers is smart on OSX.
9000 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
9001 Get hardware address with getifaddrs if available.
9003 2011-08-12 Eli Zaretskii <eliz@gnu.org>
9005 * xdisp.c (iterate_out_of_display_property): xassert that
9006 IT->position is set to within IT->object's boundaries. Break from
9007 the loop as soon as EOB is reached; avoids infloops in redisplay
9008 when IT->position is set up wrongly due to some bug.
9009 Set IT->current to match the bidi iterator unconditionally.
9010 (push_display_prop): Allow GET_FROM_STRING as IT->method on
9011 entry. Force push_it to save on the stack the current
9012 buffer/string position, to be restored by pop_it. Fix flags in
9013 the iterator structure wrt the object coming from a display
9014 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
9015 properties. (Bug#9284)
9017 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
9019 * fontset.c (fontset_get_font_group): Add proper type checks.
9020 (Bug#9172)
9022 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
9024 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
9025 and LC_VERSION_MIN_MACOSX.
9026 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
9027 (dump_it) [LC_FUNCTION_STARTS]: Use it.
9029 2011-08-08 Eli Zaretskii <eliz@gnu.org>
9031 * xdisp.c (forward_to_next_line_start): Allow to use the
9032 no-display-properties-and-no-overlays under bidi display.
9033 Set disp_pos in the bidi iterator to avoid searches for display
9034 properties and overlays.
9036 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
9038 * editfns.c (Fset_time_zone_rule): Document relationship with the
9039 setenv function.
9041 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
9042 the font entity extracted from the cache (Bug#8109).
9044 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
9046 * composite.c (autocmp_chars): Don't reset point. That is done by
9047 restore_point_unwind (Bug#5984).
9049 2011-08-07 Juri Linkov <juri@jurta.org>
9051 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
9052 to show the arg `TIME' instead of `TIMEVAL'.
9054 2011-08-06 Eli Zaretskii <eliz@gnu.org>
9056 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
9057 display property strides EOL and includes a newline, as in
9058 longlines-mode. (Bug#9254)
9059 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
9060 word-wrap under bidirectional display. (Bug#9224)
9062 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
9063 is non-zero, even if the data buffer is NULL. Fixes a crash in
9064 vertical-motion with longlines-mode. (Bug#9254)
9066 2011-08-05 Eli Zaretskii <eliz@gnu.org>
9068 * bidi.c <bidi_cache_total_alloc>: Now static.
9069 (bidi_initialize): Initialize bidi_cache_total_alloc.
9071 * xdisp.c (display_line): Release buffer allocated for shelved bidi
9072 cache. (Bug#9221)
9074 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
9075 amount allocated this far in `bidi_cache_total_alloc'.
9076 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
9077 non-zero, only free the data buffer without restoring the cache
9078 contents. All callers changed.
9080 * dispextern.h (bidi_unshelve_cache): Update prototype.
9082 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
9083 (move_it_in_display_line, move_it_to)
9084 (move_it_vertically_backward, move_it_by_lines): Replace the call
9085 to xfree to an equivalent call to bidi_unshelve_cache.
9086 (move_it_in_display_line_to): Fix logic of returning
9087 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
9089 2011-08-05 Eli Zaretskii <eliz@gnu.org>
9091 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
9092 came from a string character with a `cursor' property. (Bug#9229)
9094 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
9096 * Makefile.in (LIB_PTHREAD): New variable.
9097 (LIBES): Add LIB_PTHREAD (Bug#9216).
9099 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
9100 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
9102 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
9104 * regex.c (re_iswctype): Remove some redundant boolean conversions.
9106 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
9108 * xterm.c (x_find_topmost_parent): New function.
9109 (x_set_frame_alpha): Find topmost parent window with
9110 x_find_topmost_parent and set the property there also (bug#9181).
9111 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
9113 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
9115 * callproc.c (Fcall_process): Avoid vfork clobbering
9116 the local vars buffer, coding_systems, current_dir.
9118 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
9120 * keymap.c (Fmake_composed_keymap): Move to subr.el.
9122 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
9124 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
9125 so that it is not optimized away.
9127 * xdisp.c (compute_display_string_pos): Remove unused local.
9129 2011-08-02 Eli Zaretskii <eliz@gnu.org>
9131 Fix slow cursor motion and scrolling in large buffers with
9132 selective display, like Org Mode buffers. (Bug#9218)
9134 * dispextern.h (struct bidi_it): New member disp_prop_p.
9136 * xdisp.c: Remove one-slot cache of display string positions.
9137 (compute_display_string_pos): Accept an additional argument
9138 DISP_PROP_P; callers changed. Scan at most 5K characters forward
9139 for a display string or property. If found, set DISP_PROP_P
9140 non-zero.
9142 * bidi.c (bidi_fetch_char): Accept an additional argument
9143 DISP_PROP_P, and pass it to compute_display_string_pos.
9144 Only handle text covered by a display string if DISP_PROP_P is returned
9145 non-zero. All callers of bidi_fetch_char changed.
9147 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
9149 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
9151 2010-12-03 Don March <don@ohspite.net>
9153 * keymap.c (Fdefine_key): Fix non-prefix key error message when
9154 last character M-[char] is translated to ESC [char] (bug#7541).
9156 2011-08-02 Kenichi Handa <handa@m17n.org>
9158 * lisp.h (uniprop_table): Extern it.
9160 * chartab.c (uniprop_table): Make it non-static.
9162 2011-08-01 Eli Zaretskii <eliz@gnu.org>
9164 * xdisp.c (forward_to_next_line_start): Accept additional argument
9165 BIDI_IT_PREV, and store into it the state of the bidi iterator had
9166 on the newline.
9167 (reseat_at_next_visible_line_start): Use the bidi iterator state
9168 returned by forward_to_next_line_start to restore the state of
9169 it->bidi_it after backing up to previous newline. (Bug#9212)
9171 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
9173 * regex.c (re_comp): Protoize.
9174 (re_exec): Fix return type.
9175 (regexec): Fix type of `ret'. (Bug#9203)
9177 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
9179 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
9180 This is needed if max-image-size is a floating-point number.
9182 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
9184 * print.c (print_object): Print empty symbol as ##.
9186 * lread.c (read1): Read ## as empty symbol.
9188 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
9190 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
9191 setting frame foreground color (Bug#9175).
9192 (x_set_background_color): Likewise.
9194 * nsmenu.m (-setText): Size tooltip dimensions precisely to
9195 contents (Bug#9176).
9196 (EmacsTooltip -init): Remove bezels and add shadows to
9197 tooltip windows.
9199 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
9200 or scroll bar (Bug#8470).
9202 * nsfont.m (nsfont_open): Remove assignment to voffset and
9203 unnecessary vars hshink, expand, hd, full_height, min_height.
9204 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
9206 * nsterm.h (nsfont_info): Remove voffset field.
9208 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
9210 Implement strike-through and overline on NextStep (Bug#8863).
9212 * nsfont.m (nsfont_open): Use underline position provided by font,
9213 instead of hard-coded value of 2.
9214 (nsfont_draw): Call ns_draw_text_decoration instead.
9216 * nsterm.h: Add declaration for ns_draw_text_decoration.
9218 * nsterm.m (ns_draw_text_decoration): New function for drawing
9219 underline, overline, and strike-through.
9220 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
9221 ns_draw_text_decoration. Change treatment of cursor drawing to
9222 accommodate underlining, etc.
9224 2011-07-28 Eli Zaretskii <eliz@gnu.org>
9226 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
9227 default.
9229 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
9231 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
9232 Without this fix, if a signal arrives just after memory fills up,
9233 'malloc' might be invoked reentrantly.
9235 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
9236 In other words, assume that every image size is allowed, on non-X
9237 hosts. This assumption is probably wrong, but it lets Emacs compile.
9239 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
9241 * regex.c (re_iswctype): Convert return values to boolean.
9243 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
9245 * xdisp.c (compute_display_string_pos): Don't use cached display
9246 string position if the buffer had its restriction changed.
9247 (Bug#9184)
9249 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
9251 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
9253 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
9255 Integer signedness and overflow and related fixes. (Bug#9079)
9257 * bidi.c: Integer size and overflow fixes.
9258 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
9259 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
9260 (bidi_cache_find_level_change, bidi_cache_ensure_space)
9261 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
9262 (bidi_find_other_level_edge):
9263 Use ptrdiff_t instead of EMACS_INT where either will do.
9264 This works better on 32-bit hosts configured --with-wide-int.
9265 (bidi_cache_ensure_space): Check for size-calculation overflow.
9266 Use % rather than repeated addition, for better worst-case speed.
9267 Don't set bidi_cache_size until after xrealloc returns, because it
9268 might not return.
9269 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
9270 (bidi_cache_ensure_space): Also check that the bidi cache size
9271 does not exceed that of the largest Lisp string or buffer. See Eli
9272 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
9274 * alloc.c (__malloc_size_t): Remove.
9275 All uses replaced by size_t. See Andreas Schwab's note
9276 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
9278 * image.c: Improve checking for integer overflow.
9279 (check_image_size): Assume that f is nonnull, since
9280 it is always nonnull in practice. This is one less thing to
9281 worry about when checking for integer overflow later.
9282 (x_check_image_size): New function, which checks for integer
9283 overflow issues inside X.
9284 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
9285 This removes the need for a memory_full check.
9286 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
9287 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
9288 (xbm_read_bitmap_data): Change locals back to 'int', since
9289 their values must fit in 'int'.
9290 (xpm_load_image, png_load, tiff_load):
9291 Invoke x_create_x_image_and_pixmap earlier,
9292 to avoid much needless work if the image is too large.
9293 (tiff_load): Treat overly large images as if
9294 x_create_x_image_and_pixmap failed, not as malloc failures.
9295 (gs_load): Use x_check_image_size.
9297 * gtkutil.c: Omit integer casts.
9298 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
9299 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
9301 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
9303 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
9304 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
9305 would wrongly return t on a 64-bit host.
9307 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
9308 The plain *_OVERFLOW macros run afoul of GCC bug 49705
9309 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
9310 and therefore cause GCC to emit a bogus diagnostic in some cases.
9312 * image.c: Integer signedness and overflow and related fixes.
9313 This is not an exhaustive set of fixes, but it's time to
9314 record what I've got.
9315 (lookup_pixel_color, check_image_size): Remove redundant decls.
9316 (check_image_size): Don't assume that arbitrary EMACS_INT values
9317 fit in 'int', or that arbitrary 'double' values fit in 'int'.
9318 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
9319 (tiff_load, imagemagick_load_image):
9320 Check for overflow in size calculations.
9321 (x_create_x_image_and_pixmap): Remove unnecessary test for
9322 xmalloc returning NULL; that can't happen.
9323 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
9324 (xpm_color_bucket): Use better integer hashing function.
9325 (xpm_cache_color): Don't possibly over-allocate memory.
9326 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
9327 (gif_memory_source):
9328 Use ptrdiff_t, not int or size_t, to record sizes.
9329 (png_load): Don't assume values greater than 2**31 fit in 'int'.
9330 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
9331 either works, as we prefer signed integers.
9332 (tiff_read_from_memory, tiff_write_from_memory):
9333 Return tsize_t, not size_t, since that's what the TIFF API wants.
9334 (tiff_read_from_memory): Don't fail simply because the read would
9335 go past EOF; instead, return a short read.
9336 (tiff_load): Omit no-longer-needed casts.
9337 (Fimagemagick_types): Don't assume size fits into 'int'.
9339 Improve hashing quality when configured --with-wide-int.
9340 * fns.c (hash_string): New function, taken from sxhash_string.
9341 Do not discard information about ASCII character case; this
9342 discarding is no longer needed.
9343 (sxhash-string): Use it. Change sig to match it. Caller changed.
9344 * lisp.h: Declare it.
9345 * lread.c (hash_string): Remove, since we now use fns.c's version.
9346 The fns.c version returns a wider integer if --with-wide-int is
9347 specified, so this should help the quality of the hashing a bit.
9349 * emacs.c: Integer overflow minor fix.
9350 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
9351 Define only if GNU_LINUX.
9352 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
9354 * dispnew.c: Integer signedness and overflow fixes.
9355 Remove unnecessary forward decls, that were a maintenance hassle.
9356 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
9357 All uses changed.
9358 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
9359 (scrolling_window): Use ptrdiff_t, not int, for byte count.
9360 (prepare_desired_row, line_draw_cost):
9361 Use int, not unsigned, where either works.
9362 (save_current_matrix, restore_current_matrix):
9363 Use ptrdiff_t, not size_t, where either works.
9364 (init_display): Check for overflow more accurately, and without
9365 relying on undefined behavior.
9367 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
9368 Remove, replacing with the new symbols in lisp.h. All uses changed.
9369 * fileio.c (make_temp_name):
9370 * filelock.c (lock_file_1, lock_file):
9371 * xdisp.c (message_dolog):
9372 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
9373 Use pMd etc. instead.
9374 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
9375 replacing the pWIDE etc. symbols removed from editfns.c.
9377 * keyboard.h (num_input_events): Now uintmax_t.
9378 This is (very slightly) less likely to mess up due to wraparound.
9379 All uses changed.
9381 * buffer.c: Integer signedness fixes.
9382 (alloc_buffer_text, enlarge_buffer_text):
9383 Use ptrdiff_t rather than size_t when either will do, as we prefer
9384 signed integers.
9386 * alloc.c: Integer signedness and overflow fixes.
9387 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
9388 (__malloc_size_t): Default to size_t, not to int.
9389 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
9390 (Fgarbage_collect, mark_object_loop_halt, mark_object):
9391 Prefer ptrdiff_t to size_t when either would do, as we prefer
9392 signed integers.
9393 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
9394 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
9395 Now const. Initialize with values that are in range even if char
9396 is signed.
9397 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
9398 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
9399 These functions do the right thing with sizes > 2**32.
9400 (check_depth): Now ptrdiff_t, not int.
9401 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
9402 Adjust to new way of storing sizes. Check for size overflow bugs
9403 in rest of code.
9404 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
9405 slightly wrong anyway, as it missed one instance of
9406 XMALLOC_OVERRUN_CHECK_OVERHEAD.
9407 (refill_memory_reserve): Omit needless cast to size_t.
9408 (mark_object_loop_halt): Mark as externally visible.
9410 * xselect.c: Integer signedness and overflow fixes.
9411 (Fx_register_dnd_atom, x_handle_dnd_message):
9412 Use ptrdiff_t, not size_t, since we prefer signed.
9413 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
9414 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
9415 x_dnd_atoms_size and x_dnd_atoms_length.
9417 * doprnt.c: Prefer signed to unsigned when either works.
9418 * eval.c (verror):
9419 * doprnt.c (doprnt):
9420 * lisp.h (doprnt):
9421 * xdisp.c (vmessage):
9422 Use ptrdiff_t, not size_t, when using or implementing doprnt,
9423 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
9424 prefer signed arithmetic to avoid comparison confusion.
9425 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
9426 but is a bit tricky.
9428 Assume freestanding C89 headers, string.h, stdlib.h.
9429 * data.c, doprnt.c, floatfns.c, print.c:
9430 Include float.h unconditionally.
9431 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
9432 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
9433 * regex.c: Likewise for stddef.h, string.h.
9434 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
9435 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
9436 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
9437 (STDC_HEADERS): Remove obsolete defines.
9438 * sysdep.c: Include limits.h unconditionally.
9440 Assume support for memcmp, memcpy, memmove, memset.
9441 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
9442 * regex.c (memcmp, memcpy):
9443 Remove; we assume C89 now.
9445 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
9446 (__malloc_safe_bcopy): Remove; no longer needed.
9448 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
9449 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
9450 well either way, and we prefer signed to unsigned.
9452 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
9454 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
9455 closes the connection while we're reading (bug#9182).
9457 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
9459 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
9460 are specified (Bug#9168).
9462 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
9464 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
9465 Found by GCC static checking and --with-wide-int on a 32-bit host.
9467 2011-07-25 Eli Zaretskii <eliz@gnu.org>
9469 * xdisp.c (compute_display_string_pos): Fix logic of caching
9470 previous display string position. Initialize cached_prev_pos to
9471 -1. Fixes slow-down at the beginning of a buffer.
9473 2011-07-24 Eli Zaretskii <eliz@gnu.org>
9475 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
9476 for attrs[LFACE_FONTSET_INDEX].
9478 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
9480 * xml.c (parse_region): Remove unused local
9481 that was recently introduced.
9483 2011-07-23 Eli Zaretskii <eliz@gnu.org>
9485 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
9486 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
9488 * xdisp.c (move_it_in_display_line_to): Record the best matching
9489 position for TO_CHARPOS while scanning the line, and restore it on
9490 exit if none of the characters scanned was an exact match.
9491 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
9492 when exact match is impossible due to invisible text, and the
9493 lines are truncated.
9495 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
9497 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
9498 for OSX >= 10.7.
9500 2011-07-22 Eli Zaretskii <eliz@gnu.org>
9502 Fix a significant slow-down of cursor motion with C-n, C-p,
9503 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
9504 auto-repeat under bidi redisplay in fontified buffers.
9505 * xdisp.c (compute_stop_pos_backwards): New function.
9506 (next_element_from_buffer): Call compute_stop_pos_backwards to
9507 find a suitable prev_stop when we find ourselves before
9508 base_level_stop.
9509 (reseat): Don't look for prev_stop, as that could mean a very long
9510 run.
9511 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
9512 <cached_disp_overlay_modiff>: Cache for last found display string
9513 position.
9514 (compute_display_string_pos): Return the cached position if asked
9515 about the same buffer in the same area of character positions, and
9516 the buffer wasn't changed since the time the display string
9517 position was cached.
9519 2011-07-22 Eli Zaretskii <eliz@gnu.org>
9521 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
9522 is an integer, which is important for empty lines. (Bug#9149)
9524 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
9526 * frame.c (Fmodify_frame_parameters): In tty case, update the
9527 default face if necessary (Bug#4238).
9529 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
9531 * editfns.c (Fstring_to_char): No need to explain what a character
9532 is in the docstring (Bug#6576).
9534 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
9536 * xml.c (parse_region): Make sure we always return a tree.
9538 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
9540 * xml.c (parse_region): If a document contains only comments,
9541 return that, too.
9543 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
9545 * xml.c (make_dom): Return comments, too.
9547 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
9549 Port to OpenBSD.
9550 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
9551 and the surrounding thread.
9552 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
9553 rather than fgets, and retry after EINTR. Otherwise, 'emacs
9554 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
9555 timer goes off.
9556 * s/openbsd.h (BROKEN_SIGIO): Define.
9557 * unexelf.c (unexec) [__OpenBSD__]:
9558 Don't update the .mdebug section of the Alpha COFF symbol table.
9560 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
9562 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
9563 (bug#8460).
9565 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
9567 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
9568 This fixes some race conditions on the permissions of any newly
9569 created file.
9571 * alloc.c (valid_pointer_p): Use pipe, not open.
9572 This fixes some permissions issues when debugging.
9574 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
9575 If fchown fails to set both uid and gid, try to set just gid,
9576 as that is sometimes allowed. Adjust the file's mode to eliminate
9577 setuid or setgid bits that are inappropriate if fchown fails.
9579 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
9581 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
9582 to compare Lisp_Objects.
9583 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
9584 global_gnutls_log_level, don't mistake it for a Lisp_Object.
9585 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
9587 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
9589 * lread.c (read_integer): Unread even EOF character.
9590 (read1): Likewise. Properly record start position of symbol.
9592 * lread.c (read1): Read `#:' as empty uninterned symbol if no
9593 symbol character follows.
9595 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
9597 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
9598 This works around a problem with the previous change to Fcopy_file.
9599 Recent glibc declares fchown with __attribute__((warn_unused_result)),
9600 and without this change, GCC might complain about discarding
9601 fchown's return value.
9603 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
9605 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
9607 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
9609 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
9611 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
9613 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
9614 it's used from the C level.
9616 * process.c: Use the same condition for POLL_FOR_INPUT in both
9617 keyboard.c and process.c (bug#1858).
9619 2011-07-09 Lawrence Mitchell <wence@gmx.li>
9621 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
9622 (Fgnutls_boot): Use it.
9624 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
9626 * doc.c (Fsubstitute_command_keys): Revert last change.
9628 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
9630 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
9631 quotes the next character, and doesn't affect other longer
9632 sequences (bug#8935).
9634 * lread.c (syms_of_lread): Clarify that is isn't only
9635 `eval-buffer' and `eval-defun' that's affected by
9636 `lexical-binding' (bug#8460).
9638 2011-07-15 Eli Zaretskii <eliz@gnu.org>
9640 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
9641 bidi redisplay when a line includes both an image and is truncated.
9643 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
9645 Fix minor problems found by static checking.
9646 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
9647 (elsz): Now a signed constant, not a size_t var. We prefer signed
9648 types to unsigned, to avoid integer comparison confusion. Without
9649 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
9650 "cannot optimize loop, the loop counter may overflow", a symptom
9651 of the confusion.
9652 * indent.c (Fvertical_motion): Mark locals as initialized.
9653 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
9655 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
9657 * search.c (Fre_search_backward): Mention `case-fold-search' in
9658 all the re_search_* functions (bug#8138).
9660 * keyboard.c (Fopen_dribble_file): Document when the file is
9661 closed (bug#8056).
9663 2011-07-14 Eli Zaretskii <eliz@gnu.org>
9665 * bidi.c (bidi_dump_cached_states): Fix format of displaying
9666 bidi_cache_idx.
9668 Support bidi reordering of display and overlay strings.
9669 * xdisp.c (compute_display_string_pos)
9670 (compute_display_string_end): Accept additional argument STRING.
9671 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
9672 (reseat_to_string): Initialize bidi_it->string.s and
9673 bidi_it->string.schars.
9674 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
9675 NULL (avoids a crash in bidi_paragraph_init).
9676 Initialize itb.string.lstring.
9677 (init_iterator): Call bidi_init_it only of a valid
9678 buffer position was specified. Initialize paragraph_embedding to
9679 L2R.
9680 (reseat_to_string): Initialize the bidi iterator.
9681 (display_string): If we need to ignore text properties of
9682 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
9683 original value of -1 will not work with bidi.)
9684 (compute_display_string_pos): First arg is now struct
9685 `text_pos *'; all callers changed. Support display properties on
9686 Lisp strings.
9687 (compute_display_string_end): Support display properties on Lisp
9688 strings.
9689 (init_iterator, reseat_1, reseat_to_string): Initialize the
9690 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
9691 when iterating on a string not from display properties).
9692 (compute_display_string_pos, compute_display_string_end):
9693 Fix calculation of the object to scan. Fixes an error when using
9694 arrow keys.
9695 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
9696 base_level_stop; instead, set base_level_stop to BEGV.
9697 Fixes crashes in vertical-motion.
9698 (next_element_from_buffer): Improve commentary for when
9699 the iterator is before prev_stop.
9700 (init_iterator): Initialize bidi_p from the default value of
9701 bidi-display-reordering, not from buffer-local value. Use the
9702 buffer-local value only if initializing for buffer iteration.
9703 (handle_invisible_prop): Support invisible properties on strings
9704 that are being bidi-reordered.
9705 (set_iterator_to_next): Support bidi reordering of C strings and
9706 Lisp strings.
9707 (next_element_from_string): Support bidi reordering of Lisp
9708 strings.
9709 (handle_stop_backwards): Support Lisp strings as well.
9710 (display_string): Support display of R2L glyph rows.
9711 Use IT_STRING_CHARPOS when displaying from a Lisp string.
9712 (init_iterator): Don't initialize it->bidi_p for strings
9713 here.
9714 (reseat_to_string): Initialize it->bidi_p for strings here.
9715 (next_element_from_string, next_element_from_c_string)
9716 (next_element_from_buffer): Add xassert's for correspondence
9717 between IT's object being iterated and it->bidi_it.string
9718 structure.
9719 (face_before_or_after_it_pos): Support bidi iteration.
9720 (next_element_from_c_string): Handle the case of the first string
9721 character that is not the first one in the visual order.
9722 (get_visually_first_element): New function, refactored from common
9723 parts of next_element_from_buffer, next_element_from_string, and
9724 next_element_from_c_string.
9725 (tool_bar_lines_needed, redisplay_tool_bar)
9726 (display_menu_bar): Force left-to-right direction. Add a FIXME
9727 comment for making that be controlled by a user option.
9728 (push_it, pop_it): Save and restore the state of the
9729 bidi iterator. Save and restore the bidi_p flag.
9730 (pop_it): Iterate out of display property for string iteration as
9731 well.
9732 (iterate_out_of_display_property): Support iteration over strings.
9733 (handle_single_display_spec): Set up it->bidi_it for iteration
9734 over a display string, and call bidi_init_it.
9735 (handle_single_display_spec, next_overlay_string)
9736 (get_overlay_strings_1, push_display_prop): Set up the bidi
9737 iterator for displaying display or overlay strings.
9738 (forward_to_next_line_start): Don't use the shortcut if
9739 bidi-iterating.
9740 (back_to_previous_visible_line_start): If handle_display_prop
9741 pushed the iterator stack, restore the internal state of the bidi
9742 iterator by calling bidi_pop_it same number of times.
9743 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
9744 and we are bidi-iterating, don't decrement the iterator position;
9745 instead, set the first_elt flag in the bidi iterator, to produce
9746 the same effect.
9747 (reseat_1): Remove redundant setting of string_from_display_prop_p.
9748 (push_display_prop): xassert that we are iterating a buffer.
9749 (push_it, pop_it): Save and restore paragraph_embedding member.
9750 (handle_single_display_spec, next_overlay_string)
9751 (get_overlay_strings_1, reseat_1, reseat_to_string)
9752 (push_display_prop): Set up the `unibyte' member of bidi_it.string
9753 correctly. Don't assume unibyte strings are not bidi-reordered.
9754 (compute_display_string_pos)
9755 (compute_display_string_end): Fix handling the case of C string.
9756 (push_it, pop_it): Save and restore from_disp_prop_p.
9757 (handle_single_display_spec, push_display_prop): Set the
9758 from_disp_prop_p flag.
9759 (get_overlay_strings_1): Reset the from_disp_prop_p flag.
9760 (pop_it): Call iterate_out_of_display_property only if we are
9761 popping after iteration over a string that came from a display
9762 property. Fix a typo in popping stretch info. Add an assertion
9763 for verifying that the iterator position is in sync with the bidi
9764 iterator.
9765 (handle_single_display_spec, get_overlay_strings_1)
9766 (push_display_prop): Fix initialization of paragraph direction for
9767 string when that of the parent object is not yet determined.
9768 (reseat_1): Call bidi_init_it to resync the bidi
9769 iterator with IT's position. (Bug#7616)
9770 (find_row_edges): If ROW->start.pos gives position
9771 smaller than min_pos, use it as ROW->minpos. (Bug#7616)
9772 (handle_stop, back_to_previous_visible_line_start, reseat_1):
9773 Reset the from_disp_prop_p flag.
9774 (SAVE_IT, RESTORE_IT): New macros.
9775 (pos_visible_p, face_before_or_after_it_pos)
9776 (back_to_previous_visible_line_start)
9777 (move_it_in_display_line_to, move_it_in_display_line)
9778 (move_it_to, move_it_vertically_backward, move_it_by_lines)
9779 (try_scrolling, redisplay_window, display_line): Use them when
9780 saving a temporary copy of the iterator and restoring it back.
9781 (back_to_previous_visible_line_start, reseat_1)
9782 (init_iterator): Empty the bidi cache "stack".
9783 (move_it_in_display_line_to): If iterator ended up at
9784 EOL, but we never saw any buffer positions smaller than
9785 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
9786 motion in bidi-reordered lines.
9787 (move_it_in_display_line_to): Record prev_method and prev_pos
9788 immediately before the call to set_iterator_to_next. Fixes cursor
9789 motion in bidi-reordered lines with stretch glyphs and strings
9790 displayed in margins. (Bug#8133) (Bug#8867)
9791 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
9792 TO_CHARPOS.
9793 (pos_visible_p): Support positions in bidi-reordered lines.
9794 Save and restore bidi cache.
9796 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.
9797 (bidi_paragraph_info): Delete unused struct.
9798 (bidi_cache_idx, bidi_cache_last_idx): Declare EMACS_INT.
9799 (bidi_cache_start): New variable.
9800 (bidi_cache_reset): Reset bidi_cache_idx to bidi_cache_start, not

10219 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
10220 subseconds part to the entropy, as that's a bit more random.
10221 Prefer signed to unsigned, since the signedness doesn't matter and
10222 in general we prefer signed. When given a limit, use a
10223 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
10224 latter isn't right if USE_2_TAGS_FOR_INTS.
10225 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
10226 not 0..VALMASK. Don't discard "excess" bits that random () returns.

10250 error be more correct.
10252 * fns.c (Frequire): Remove the mention of the .gz files, since

10264 (syms_of_gnutls): Remove duplicate DEFSYM for
10265 Qgnutls_bootprop_verify_hostname_error, an error for
10266 Qgnutls_bootprop_verify_error (which is no longer used).
10268 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
10269 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.

10371 * eval.c (struct backtrace): Simplify and port the data structure.
10372 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
10373 signed bit field, as this assumption is not portable and it makes
10374 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
10375 "char debug_on_exit : 1" as this is not portable either; instead,
10376 use the portable "unsigned int debug_on_exit : 1". Remove unused
10377 member evalargs. Remove obsolete comments about cc bombing out.
10379 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>
10381 * xsettings.c: Include glib-object.h, gio/gio.h if HAVE_GSETTINGS.

10424 * window.c (Fwindow_vchild): Rename to Fwindow_top_child.
10425 (Fwindow_hchild): Rename to Fwindow_left_child.
10426 (Fwindow_next): Rename to Fwindow_next_sibling.

10450 frames size_hint to set minimum and natural (Bug#8919).
10451 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
10452 and use min_width/height from frames size_hint to set
10453 min_width/height (Bug#8919).
10455 * gtkutil.c (xg_create_frame_widgets): Pass f to emacs_fixed_new.
10456 (x_wm_set_size_hint): Remove call to emacs_fixed_set_min_size.

10546 (PRINTPREPARE, printchar, strout):
10547 Don't set size unless allocation succeeds.
10549 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,

10564 (read_integer): Radix is now EMACS_INT, not int,
10565 to improve quality of diagnostics for out-of-range radices.
10566 Calculate buffer size correctly for out-of-range radices.
10567 (read1): Check for integer overflow in radices, and in
10568 read-circle numbers.
10569 (read_escape): Avoid int overflow.
10570 (Fload, openp, read_buffer_size, read1)
10571 (substitute_object_recurse, read_vector, read_list, map_obarray):
10572 Use ptrdiff_t, not int, for sizes.

10592 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
10594 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
10595 The following patches are for when GLYPH_DEBUG && !XASSERT.
10596 * dispextern.h (trace_redisplay_p, dump_glyph_string):
10597 * dispnew.c (flush_stdout):
10598 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
10599 Mark as externally visible.
10600 * dispnew.c (check_window_matrix_pointers): Now static.
10601 * dispnew.c (window_to_frame_vpos):
10602 * xfns.c (unwind_create_frame):

10610 Now static.
10611 (debug_method_add): Use va_list and vsprintf rather than relying
10612 on undefined behavior with wrong number of arguments.
10613 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
10614 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
10615 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
10616 since we're not interested in debugging glyphs with old libraries.
10617 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
10618 GCC 4.6.0's static checking.
10620 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
10622 Integer overflow and signedness fixes (Bug#8873).

10652 (Fnext_overlay_change, Fprevious_overlay_change)
10653 (mouse_face_overlay_overlaps, Foverlays_in):
10654 Use ptrdiff_t, not int, for sizes.
10655 (overlays_at, overlays_in): Check for size-calculation overflow.
10657 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
10659 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
10660 (x_session_initialize): Do not assume string length fits in int.
10662 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
10663 This is unlikely, but can occur if DPI is outlandish.
10665 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
10666 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
10668 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
10669 * xrdb.c (magic_file_p, search_magic_path):
10670 Omit last arg SUFFIX; it was always 0. All callers changed.
10671 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
10673 * xfont.c (xfont_match): Avoid need for strlen.
10675 * xfns.c: Don't assume strlen fits in int.
10676 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
10678 * xdisp.c (message_log_check_duplicate): Return intmax_t,
10679 not unsigned long, as we prefer signed integers. All callers changed.
10680 Detect integer overflow in repeat count.
10681 (message_dolog): Don't assume print length fits in 39 bytes.
10682 (display_mode_element): Don't assume strlen fits in int.
10684 * termcap.c: Don't assume sizes fit in int and never overflow.
10685 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
10686 (gobble_line): Check for size-calculation overflow.
10688 * minibuf.c (Fread_buffer):
10689 * lread.c (intern, intern_c_string):
10690 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
10691 Don't assume string length fits in int.
10693 * keyboard.c (parse_tool_bar_item):
10694 * gtkutil.c (style_changed_cb): Avoid need for strlen.
10696 * font.c: Don't assume string length fits in int.
10697 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
10698 Use ptrdiff_t, not int.
10699 (font_intern_prop): Don't assume string length fits in int.
10700 Don't assume integer property fits in fixnum.
10701 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
10703 * filelock.c: Fix some buffer overrun and integer overflow issues.
10704 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
10705 Reformulate so as not to need the command string.
10706 Invoke gzip -cd rather than gunzip, as it's more portable.
10707 (lock_info_type, lock_file_1, lock_file):
10708 Don't assume pid_t and time_t fit in unsigned long.
10709 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
10710 (current_lock_owner): Prefer signed type for sizes.
10711 Use memcpy, not strncpy, where memcpy is what is really wanted.
10712 Don't assume (via atoi) that time_t and pid_t fit in int.
10713 Check for time_t and/or pid_t out of range, e.g., via a network share.
10714 Don't alloca where an auto var works fine.
10716 * fileio.c: Fix some integer overflow issues.
10717 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
10718 Don't assume string length fits in int.
10719 (directory_file_name): Don't assume string length fits in long.
10720 (make_temp_name): Don't assume pid fits in int, or that its print
10721 length is less than 20.
10723 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
10725 * coding.c (make_subsidiaries): Don't assume string length fits in int.
10727 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
10729 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
10730 We prefer signed integers, even for size calculations.
10732 * emacs.c: Don't assume string length fits in 'int'.
10733 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
10734 (main): Don't invoke strlen when not needed.
10736 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
10737 (XD_DEBUG_MESSAGE): Don't waste a byte.
10739 * callproc.c (getenv_internal_1, getenv_internal)
10740 (Fgetenv_internal):
10741 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
10743 * lread.c (invalid_syntax): Omit length argument.
10744 All uses changed. This doesn't fix a bug, but it simplifies the
10745 code away from its former Hollerith-constant appearance, and it's
10746 one less 'int' to worry about when looking at integer-overflow issues.
10747 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
10749 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
10750 This didn't break anything, but it didn't help either.
10751 It's confusing to put a bogus integer in a place where the actual
10752 value does not matter.
10753 (LIST_END_P): Remove unused macro and its bogus comment.
10754 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
10756 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
10757 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
10758 implementation.
10759 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
10760 We prefer signed types, and the value cannot exceed the EMACS_INT
10761 range anyway (because otherwise the length would not be representable).
10762 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
10763 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
10764 This avoids a GCC warning when WIDE_EMACS_INT.
10766 * indent.c (sane_tab_width): New function.
10767 (current_column, scan_for_column, Findent_to, position_indentation)
10768 (compute_motion): Use it. This is just for clarity.
10769 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
10771 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
10773 * lisp.h (lint_assume): New macro.
10774 * composite.c (composition_gstring_put_cache):
10775 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
10777 * editfns.c, insdel.c:
10778 Omit unnecessary forward decls, to simplify future changes.
10780 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
10782 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
10784 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
10785 Use much-faster test for byte-length change.
10786 Don't assume string byte-length fits in 'int'.
10787 Check that character arg fits in 'int'.
10788 (mapcar1): Declare byte as byte, for clarity.
10790 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
10792 * fns.c (concat): Catch string overflow earlier.
10793 Do not rely on integer wraparound.
10795 * dispextern.h (struct it.overlay_strings_charpos)
10796 (struct it.selective): Now EMACS_INT, not int.
10797 * xdisp.c (forward_to_next_line_start)
10798 (back_to_previous_visible_line_start)
10799 (reseat_at_next_visible_line_start, next_element_from_buffer):
10800 Don't arbitrarily truncate the value of 'selective' to int.
10802 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
10804 * composite.c: Don't truncate sizes to 'int'.
10805 (composition_gstring_p, composition_reseat_it)
10806 (composition_adjust_point): Use EMACS_INT, not int.
10807 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
10808 not EMACS_UINT, for indexes.
10810 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
10812 * buffer.c: Include <verify.h>.
10813 (struct sortvec.priority, struct sortstr.priority):
10814 Now EMACS_INT, not int.
10815 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
10816 (struct sortstr.size, record_overlay_string)
10817 (struct sortstrlist.size, struct sortlist.used):
10818 Don't truncate size to int.
10819 (record_overlay_string): Check for size-calculation overflow.
10820 (init_buffer_once): Check at compile-time, not run-time.
10822 2011-06-22 Jim Meyering <meyering@redhat.com>
10824 Don't leak an XBM-image-sized buffer
10825 * image.c (xbm_load): Free the image buffer after using it.
10827 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
10829 Port to Sun C.
10830 * composite.c (find_automatic_composition): Omit needless 'return 0;'
10831 that Sun C diagnosed.
10832 * fns.c (secure_hash): Fix pointer signedness issue.
10833 * intervals.c (static_offset_intervals): New function.
10834 (offset_intervals): Use it.
10836 2011-06-21 Leo Liu <sdl.web@gmail.com>
10838 * deps.mk (fns.o):
10839 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
10840 sha512.h.
10842 * fns.c (secure_hash): Rename from crypto_hash_function and change
10843 the first arg to accept symbols.
10844 (Fsecure_hash): New primitive.
10845 (syms_of_fns): New symbols.
10847 2011-06-20 Deniz Dogan <deniz@dogan.se>
10849 * process.c (Fset_process_buffer): Clarify return value in
10850 docstring.
10852 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
10854 * dispnew.c (add_window_display_history): Use BVAR.
10856 * xdisp.c (debug_method_add): Use BVAR.
10857 (check_window_end, dump_glyph_matrix, dump_glyph)
10858 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
10860 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
10861 Likewise.
10863 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
10864 check till after the cache is created in init_frame_faces.
10866 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
10868 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
10870 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
10872 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
10873 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
10874 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
10876 Improve buffer-overflow checking (Bug#8873).
10877 * fileio.c (Finsert_file_contents):
10878 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
10879 Remove the old (too-loose) buffer overflow checks.
10880 They weren't needed, since make_gap checks for buffer overflow.
10881 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
10882 The old code merely checked for Emacs fixnum overflow, and relied
10883 on undefined (wraparound) behavior. The new code avoids undefined
10884 behavior, and also checks for ptrdiff_t and/or size_t overflow.
10886 * editfns.c (Finsert_char): Don't dump core with very negative counts.
10887 Tune. Don't use wider integers than needed. Don't use alloca.
10888 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
10890 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
10892 * insdel.c, lisp.h (buffer_overflow): New function.
10893 (insert_from_buffer_1, replace_range, replace_range_2):
10894 * insdel.c (make_gap_larger):
10895 * editfns.c (Finsert_char):
10896 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
10898 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
10900 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
10902 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
10904 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
10905 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
10907 * fileio.c: Don't assume EMACS_INT fits in off_t.
10908 (emacs_lseek): New static function.
10909 (Finsert_file_contents, Fwrite_region): Use it.
10910 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
10912 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
10914 * fns.c: Don't overflow int when computing a list length.
10915 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
10916 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
10917 truncation on 64-bit hosts. Check for QUIT every
10918 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
10919 faster and is responsive enough.
10920 (Flength): Report an error instead of overflowing an integer.
10921 (Fsafe_length): Return a float if the value is not representable
10922 as a fixnum. This shouldn't happen except in contrived situations.
10923 (Fnthcdr, Fsort): Don't assume list length fits in int.
10924 (Fcopy_sequence): Don't assume vector length fits in int.
10926 * alloc.c: Check that resized vectors' lengths fit in fixnums.
10927 (header_size, word_size): New constants.
10928 (allocate_vectorlike): Don't check size overflow here.
10929 (allocate_vector): Check it here instead, since this is the only
10930 caller of allocate_vectorlike that could cause overflow.
10931 Check that the new vector's length is representable as a fixnum.
10933 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
10934 The previous code was bogus. For example, next_almost_prime (32)
10935 returned 39, which is undesirable as it is a multiple of 3; and
10936 next_almost_prime (24) returned 25, which is a multiple of 5 so
10937 why was the code bothering to check for multiples of 7?
10939 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
10941 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
10943 Variadic C functions now count arguments with ptrdiff_t.
10944 This partly undoes my 2011-03-30 change, which replaced int with size_t.
10945 Back then I didn't know that the Emacs coding style prefers signed int.
10946 Also, in the meantime I found a few more instances where arguments
10947 were being counted with int, which may truncate counts on 64-bit
10948 machines, or EMACS_INT, which may be unnecessarily wide.
10949 * lisp.h (struct Lisp_Subr.function.aMANY)
10950 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
10951 Arg counts are now ptrdiff_t, not size_t.
10952 All variadic functions and their callers changed accordingly.
10953 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
10954 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
10955 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
10956 * callint.c (Fcall_interactively): Check arg count for overflow,
10957 to avoid potential buffer overrun. Use signed char, not 'int',
10958 for 'varies' array, so that we needn't bother to check its size
10959 calculation for overflow.
10960 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
10961 * eval.c (apply_lambda):
10962 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
10963 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
10964 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
10966 * callint.c (Fcall_interactively): Don't use index var as event count.
10968 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
10969 * mem-limits.h (SIZE): Remove; no longer used.
10971 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
10973 Remove unnecessary casts.
10974 * xterm.c (x_term_init):
10975 * xfns.c (x_set_border_pixel):
10976 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
10977 These aren't needed now that we assume ANSI C.
10979 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
10980 It's more likely to cause problems (due to unsigned overflow)
10981 than to cure them.
10983 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
10985 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
10987 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
10989 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
10991 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
10993 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
10995 GLYPH_CODE_FACE returns EMACS_INT, not int.
10996 * dispextern.h (merge_faces):
10997 * xfaces.c (merge_faces):
10998 * xdisp.c (get_next_display_element, next_element_from_display_vector):
10999 Don't assume EMACS_INT fits in int.
11001 * character.h (CHAR_VALID_P): Remove unused parameter.
11002 * fontset.c, lisp.h, xdisp.c: All uses changed.
11004 * editfns.c (Ftranslate_region_internal): Omit redundant test.
11006 * fns.c (concat): Minor tuning based on overflow analysis.
11007 This doesn't fix any bugs. Use int to hold character, instead
11008 of constantly refetching from Emacs object. Use XFASTINT, not
11009 XINT, for value known to be a character. Don't bother comparing
11010 a single byte to 0400, as it's always less.
11012 * floatfns.c (Fexpt):
11013 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
11015 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
11016 for characters.
11018 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
11020 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
11021 Without this fix, on a 64-bit host (aset S 0 4294967386) would
11022 incorrectly succeed when S was a string, because 4294967386 was
11023 truncated before it was used.
11025 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
11026 Otherwise, an out-of-range integer could cause undefined behavior
11027 on a 64-bit host.
11029 * composite.c: Use int, not EMACS_INT, for characters.
11030 (fill_gstring_body, composition_compute_stop_pos): Use int, not
11031 EMACS_INT, for values that are known to be in character range.
11032 This doesn't fix any bugs but is the usual style inside Emacs and
11033 may generate better code on 32-bit machines.
11035 Make sure a 64-bit char is never passed to ENCODE_CHAR.
11036 This is for reasons similar to the recent CHAR_STRING fix.
11037 * charset.c (Fencode_char): Check that character arg is actually
11038 a character. Pass an int to ENCODE_CHAR.
11039 * charset.h (ENCODE_CHAR): Verify that the character argument is no
11040 wider than 'int', as a compile-time check to prevent future regressions
11041 in this area.
11043 * character.c (char_string): Remove unnecessary casts.
11045 Make sure a 64-bit char is never passed to CHAR_STRING.
11046 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
11047 by silently ignoring the top 32 bits, allowing some values
11048 that were far too large to be valid characters.
11049 * character.h: Include <verify.h>.
11050 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
11051 arguments are no wider than unsigned, as a compile-time check
11052 to prevent future regressions in this area.
11053 * data.c (Faset):
11054 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
11055 (Fsubst_char_in_region):
11056 * fns.c (concat):
11057 * xdisp.c (decode_mode_spec_coding):
11058 Adjust to CHAR_STRING's new requirement.
11059 * editfns.c (Finsert_char, Fsubst_char_in_region):
11060 * fns.c (concat): Check that character args are actually
11061 characters. Without this test, these functions did the wrong
11062 thing with wildly out-of-range values on 64-bit hosts.
11064 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
11065 These casts should not be needed on 32-bit hosts, either.
11066 * keyboard.c (read_char):
11067 * lread.c (Fload): Remove casts to unsigned.
11069 * lisp.h (UNSIGNED_CMP): New macro.
11070 This fixes comparison bugs on 64-bit hosts.
11071 (ASCII_CHAR_P): Use it.
11072 * casefiddle.c (casify_object):
11073 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
11074 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
11075 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
11076 * dispextern.h (FACE_FROM_ID):
11077 * keyboard.c (read_char): Use UNSIGNED_CMP.
11079 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
11080 not to EMACS_INT, to avoid GCC warning.
11082 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
11084 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
11085 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
11086 isn't needed on 32-bit machines.
11088 * buffer.c (Fgenerate_new_buffer_name):
11089 Use EMACS_INT for count, not int.
11090 (advance_to_char_boundary): Return EMACS_INT, not int.
11092 * data.c (Qcompiled_function): Now static.
11094 * window.c (window_body_lines): Now static.
11096 * image.c (gif_load): Rename local to avoid shadowing.
11098 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
11099 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
11100 * alloc.c (make_save_value): Integer argument is now of type
11101 ptrdiff_t, not int.
11102 (mark_object): Use ptrdiff_t, not int.
11103 * lisp.h (pD): New macro.
11104 * print.c (print_object): Use it.

11135 The definition here is exact; the one in lisp.h was approximate.
11136 (allocate_string_data): Check for string overflow. This catches
11137 some instances we weren't catching before. Also, it catches
11138 size_t overflow on (unusual) hosts where SIZE_MAX <= min
11139 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
11140 and ptrdiff_t and EMACS_INT are both 64 bits.
11142 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
11143 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.

11649 Do not assume that spare memory exists; that assumption is valid
11650 only if SYSTEM_MALLOC.
11651 (LARGE_REQUEST): New macro, so that the issue of large requests
11652 is separated from the issue of spare memory.

11721 instead of using explicit *_CHAR codes.
11722 (bidi_resolve_explicit, bidi_resolve_weak):
11723 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
11724 bidirectional text is supported only in multibyte buffers.

11733 were just reseat()'ed to a new position.
11735 * xdisp.c (set_cursor_from_row): Set start and stop points
11736 according to the row's direction when priming the loop that looks
11737 for the glyph on which to display cursor.
11738 (single_display_spec_intangible_p): Function deleted.
11739 (display_prop_intangible_p): Reimplement to call
11740 handle_display_spec instead of single_display_spec_intangible_p.
11741 Accept 3 additional arguments needed by handle_display_spec.
11742 This fixes incorrect cursor motion across display property with complex
11743 values: lists, `(when COND...)' forms, etc.

11745 lists with the argument STRING its top-level element.
11746 (display_prop_string_p): Fix the condition for processing a

11749 last portion of handle_display_prop.
11750 (compute_display_string_pos): Accept additional argument
11751 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
11752 value of a `display' property is a "replacing spec".
11753 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
11754 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
11755 the display property, but just return a value indicating whether

11757 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
11758 frame_window_p members of struct bidi_it.

11765 * keyboard.c (adjust_point_for_property): Adjust the call to
11766 display_prop_intangible_p to its new signature.
11768 * dispextern.h (struct bidi_it): New member frame_window_p.

11782 All callers changed. (Bug#8762)
11784 * gnutls.c: Use Emacs's memory allocators.
11785 Without this change, the gnutls library would invoke malloc etc.
11786 directly, which causes problems on non-SYNC_INPUT hosts, and which
11787 runs afoul of improving memory_full behavior. (Bug#8761)
11788 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
11789 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
11790 xfree instead of the default malloc, realloc, free.
11791 (Fgnutls_boot): No need to check for memory allocation failure,
11792 since xmalloc does that for us.
11794 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
11795 * category.c (hash_get_category_set):
11796 * ccl.c (ccl_driver):

11812 * lisp.h (struct Lisp_Hash_Table):
11813 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
11814 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
11815 for hashes and hash indexes, instead of 'unsigned' and 'int'.
11816 * alloc.c (allocate_vectorlike):

11818 * ccl.c (ccl_driver):
11819 Check for overflow when converting EMACS_INT to int.

11821 need to be updated by these changes.
11822 * fns.c (make_hash_table, maybe_resize_hash_table):
11823 Check for integer overflow with large hash tables.
11824 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
11825 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
11826 (SXHASH_REDUCE): New macro.
11827 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
11828 Use it instead of discarding useful hash info with large hash values.
11829 (sxhash_float): New function.
11830 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
11831 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
11832 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
11833 Rewrite to use FIXNUM_BITS, as this simplifies things.
11834 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
11835 Adjust signatures to match updated version of code.
11836 (consing_since_gc): Now EMACS_INT, since a single hash table can
11837 use more than INT_MAX bytes.

11886 Make it possible to run ./temacs.
11888 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
11889 syms_of_callproc does the same thing. Remove test for

11950 * fns.c (to_uchar): Define.
11951 (crypto_hash_function): Use it to convert some newly-signed
11952 variables to unsigned, to avoid sign-extension bugs. For example,
11953 without this change, (md5 "truc") would evaluate to
11954 45723a2aff78ff4fff7fff1114760e62 rather than the expected
11955 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
11956 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
11958 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11960 Integer overflow fixes.
11962 * dbusbind.c: Serial number integer overflow fixes.
11963 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
11964 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
11965 to hold a serial number that is too large for a fixnum.
11966 (Fdbus_method_return_internal, Fdbus_method_error_internal):
11967 Check for serial numbers out of range. Decode any serial number
11968 that was so large that it became a float. (Bug#8722)
11970 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
11971 (Fdbus_call_method, Fdbus_call_method_asynchronously):
11972 Use XFASTINT rather than XUINT when numbers are nonnegative.
11973 (xd_append_arg, Fdbus_method_return_internal):
11974 (Fdbus_method_error_internal): Likewise. Also, for unsigned
11975 arguments, check that Lisp number is nonnegative, rather than
11976 silently wrapping negative numbers around. (Bug#8722)
11977 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
11978 (Bug#8722)
11980 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
11982 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
11984 ccl: Add integer overflow checks.
11985 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
11986 (IN_INT_RANGE): New macros.
11987 (ccl_driver): Use them to check for integer overflow when
11988 decoding a CCL program. Many of the new checks are whether XINT (x)
11989 fits in int; it doesn't always, on 64-bit hosts. The new version
11990 doesn't catch all possible integer overflows, but it's an
11991 improvement. (Bug#8719)
11993 * alloc.c (make_event_array): Use XINT, not XUINT.
11994 There's no need for unsigned here.
11996 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
11997 This follows up to the 2011-05-06 change that substituted uintptr_t
11998 for EMACS_INT. This case wasn't caught back then.
12000 Rework Fformat to avoid integer overflow issues.
12001 * editfns.c: Include <float.h> unconditionally, as it's everywhere
12002 now (part of C89). Include <verify.h>.
12003 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
12004 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
12005 (Fformat): Avoid the prepass trying to compute sizes; it was only
12006 approximate and thus did not catch overflow reliably. Instead, walk
12007 through the format just once, formatting and computing sizes as we go,
12008 checking for integer overflow at every step, and allocating a larger
12009 buffer as needed. Keep track separately whether the format is
12010 multibyte. Keep only the most-recently calculated precision, rather
12011 than them all. Record whether each argument has been converted to
12012 string. Use EMACS_INT, not int, for byte and char and arg counts.
12013 Support field widths and precisions larger than INT_MAX. Avoid
12014 sprintf's undefined behavior with conversion specifications such as %#d
12015 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
12016 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
12017 formatting out-of-range floating point numbers with int
12018 formats. (Bug#8668)
12020 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
12022 * data.c: Avoid integer truncation in expressions involving floats.
12023 * data.c: Include <intprops.h>.
12024 (arith_driver): When there's an integer overflow in an expression
12025 involving floating point, convert the integers to floating point
12026 so that the resulting value does not suffer from catastrophic
12027 integer truncation. For example, on a 64-bit host (* 4
12028 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
12029 Do not rely on undefined behavior after integer overflow.
12031 merge count_size_as_multibyte, parse_str_to_multibyte
12032 * character.c, character.h (count_size_as_multibyte):
12033 Rename from parse_str_to_multibyte; all uses changed.
12034 Check for integer overflow.
12035 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
12036 since it's now a duplicate of the other. This is more of
12037 a character than a buffer op, so better that it's in character.c.
12038 * fns.c, print.c: Adjust to above changes.
12040 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
12042 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
12044 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
12046 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
12047 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
12048 (x_clipboard_manager_save): Now static.
12049 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
12051 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
12052 (crypto_hash_function): Now static.
12053 Fix pointer signedness problems. Avoid unnecessary initializations.
12055 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
12057 * termhooks.h (Vselection_alist): Make it terminal-local.
12059 * terminal.c (create_terminal): Initialize it.
12061 * xselect.c: Support for clipboard managers.
12062 (Vselection_alist): Move to termhooks.h as terminal-local var.
12063 (LOCAL_SELECTION): New macro.
12064 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
12065 (symbol_to_x_atom): Remove gratuitous arg.
12066 (x_handle_selection_request, lisp_data_to_selection_data)
12067 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
12068 (x_own_selection, x_get_local_selection, x_convert_selection):
12069 New arg, specifying work frame. Use terminal-local Vselection_alist.
12070 (some_frame_on_display): Delete unused function.
12071 (Fx_own_selection_internal, Fx_get_selection_internal)
12072 (Fx_disown_selection_internal, Fx_selection_owner_p)
12073 (Fx_selection_exists_p): New optional frame arg.
12074 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
12075 (x_handle_selection_clear): Don't treat other terminals with the
12076 same keyboard specially. Use the terminal-local Vselection_alist.
12077 (x_clear_frame_selections): Use Frun_hook_with_args.
12079 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
12081 * xterm.h: Add support for those atoms.
12083 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
12085 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
12086 (converted_selections, conversion_fail_tag): New global variables.
12087 (x_selection_request_lisp_error): Free the above.
12088 (x_get_local_selection): Remove unnecessary code.
12089 (x_reply_selection_request): Args changed; handle arbitrary array
12090 of converted selections stored in converted_selections.
12091 Separate the XChangeProperty and SelectionNotify steps.
12092 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
12093 (x_convert_selection): New function.
12094 (x_handle_selection_event): Simplify.
12095 (x_get_foreign_selection): Don't ignore incoming requests while
12096 waiting for an answer; this will fail when we implement
12097 SAVE_TARGETS, and seems unnecessary anyway.
12098 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
12099 (Vx_sent_selection_functions): Doc fix.
12101 2011-05-26 Leo Liu <sdl.web@gmail.com>
12103 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
12105 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
12107 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
12109 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
12110 for fringe update if it has periodic bitmap.
12111 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
12112 and fringe_bitmap_periodic_p.
12114 * fringe.c (get_fringe_bitmap_data): New function.
12115 (draw_fringe_bitmap_1, update_window_fringes): Use it.
12116 (update_window_fringes): Record periodicity of fringe bitmap in glyph
12117 row. Mark glyph row for fringe update if periodicity changed.
12119 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
12120 for fringe update unless it has periodic bitmap.
12122 2011-05-25 Kenichi Handa <handa@m17n.org>
12124 * xdisp.c (get_next_display_element): Set correct it->face_id for
12125 a static composition.
12127 2011-05-24 Leo Liu <sdl.web@gmail.com>
12129 * deps.mk (fns.o):
12130 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
12132 * fns.c (crypto_hash_function, Fsha1): New function.
12133 (Fmd5): Use crypto_hash_function.
12134 (syms_of_fns): Add Ssha1.
12136 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
12138 * gnutls.c: Remove unused macros.
12139 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
12140 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
12141 Remove macros that are defined and never used.
12142 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
12144 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
12146 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
12147 (Fx_get_selection_internal): Minor cleanup.
12148 (Fx_own_selection_internal): Rename arguments for consistency with
12149 select.el.
12151 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
12153 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
12155 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
12157 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
12159 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
12161 * dispnew.c (scrolling_window): Don't exclude the case that the
12162 last enabled row in the desired matrix touches the bottom boundary.
12164 2011-05-21 Glenn Morris <rgm@gnu.org>
12166 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
12167 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
12168 and add some more files.
12170 2011-05-20 Eli Zaretskii <eliz@gnu.org>
12172 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
12173 report_file_error introduced by the change from 2011-05-07.
12175 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
12177 * systime.h (Time): Define only if emacs is defined.
12178 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
12179 where the include path doesn't have X11/X.h by default. See
12180 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
12182 2011-05-20 Kenichi Handa <handa@m17n.org>
12184 * composite.c (find_automatic_composition): Fix previous change.
12186 2011-05-20 Glenn Morris <rgm@gnu.org>
12188 * lisp.mk: New file, split from Makefile.in.
12189 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
12190 (shortlisp): Remove.
12191 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
12193 2011-05-19 Glenn Morris <rgm@gnu.org>
12195 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
12196 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
12197 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
12198 (lisp): Set the order to that of loadup.el.
12199 (shortlisp): Make it a copy of $lisp.
12200 (SOME_MACHINE_LISP): Remove.
12201 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
12202 Use just $shortlisp, not $SOME_MACHINE_LISP too.
12204 2011-05-18 Kenichi Handa <handa@m17n.org>
12206 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
12207 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
12208 (find_automatic_composition): Mostly rewrite for efficiency.
12210 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
12212 * makefile.w32-in: Update dependencies.
12214 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
12216 * menu.c: Include limits.h (fixes the MS-Windows build broken by
12217 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
12219 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
12221 Fix some integer overflow issues, such as string length overflow.
12223 * insdel.c (count_size_as_multibyte): Check for string overflow.
12225 * character.c (lisp_string_width): Check for string overflow.
12226 Use EMACS_INT, not int, for string indexes and lengths; in
12227 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
12228 the resulting string length overflows an EMACS_INT; instead,
12229 report a string overflow if no precision given. When checking for
12230 precision exhaustion, use a check that cannot possibly have
12231 integer overflow. (Bug#8675)
12232 * character.h (lisp_string_width): Adjust to new signature.
12234 * alloc.c (string_overflow): New function.
12235 (Fmake_string): Use it. This doesn't change behavior, but saves
12236 a few bytes and will simplify future changes.
12237 * character.c (string_escape_byte8): Likewise.
12238 * lisp.h (string_overflow): New decl.
12240 Fixups, following up to the user-interface timestamp change.
12241 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
12242 for UI timestamps, instead of unsigned long.
12243 * msdos.c (mouse_get_pos): Likewise.
12244 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
12245 * w32gui.h (Time): Define by including "systime.h" rather than by
12246 declaring it ourselves. (Bug#8664)
12248 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
12249 * image.c (clear_image_cache): Likewise.
12251 * term.c (term_mouse_position): Don't assume time_t wraparound.
12253 Be more systematic about user-interface timestamps.
12254 Before, the code sometimes used 'Time', sometimes 'unsigned long',
12255 and sometimes 'EMACS_UINT', to represent these timestamps.
12256 This change causes it to use 'Time' uniformly, as that's what X uses.
12257 This makes the code easier to follow, and makes it easier to catch
12258 integer overflow bugs such as Bug#8664.
12259 * frame.c (Fmouse_position, Fmouse_pixel_position):
12260 Use Time, not unsigned long, for user-interface timestamps.
12261 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
12262 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
12263 * keyboard.h (last_event_timestamp): Likewise.
12264 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
12265 * menu.h (xmenu_show): Likewise.
12266 * term.c (term_mouse_position): Likewise.
12267 * termhooks.h (struct input_event.timestamp): Likewise.
12268 (struct terminal.mouse_position_hook): Likewise.
12269 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
12270 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
12271 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
12272 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
12273 what it was before.
12274 * menu.h, termhooks.h: Include "systime.h", for Time.
12276 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
12277 Don't assume that the difference between two unsigned long values
12278 can fit into an integer. At this point, we know button_down_time
12279 <= event->timestamp, so the difference must be nonnegative, so
12280 there's no need to cast the result if double-click-time is
12281 nonnegative, as it should be; check that it's nonnegative, just in
12282 case. This bug is triggered when events are more than 2**31 ms
12283 apart (about 25 days). (Bug#8664)
12285 * xselect.c (last_event_timestamp): Remove duplicate decl.
12286 (x_own_selection): Remove needless cast to unsigned long.
12288 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
12289 that always fit in int. Use a sentinel instead of a counter, to
12290 avoid a temp and to allay GCC's concerns about possible int overflow.
12291 * frame.h (struct frame): Use int for menu_bar_items_used
12292 instead of EMACS_INT, since it always fits in int.
12294 * menu.c (grow_menu_items): Check for int overflow.
12296 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
12298 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
12299 Before, the code was not consistent. These values cannot exceed
12300 2**31 - 1 so there's no need to make them unsigned.
12301 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
12302 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
12303 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
12304 as modifiers.
12305 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
12307 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
12308 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
12309 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
12310 presumably because the widths might not match.
12312 * window.c (size_window): Avoid needless test at loop start.
12314 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
12316 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
12318 2011-05-12 Drew Adams <drew.adams@oracle.com>
12320 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
12322 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
12324 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
12325 `width' to `bar_area_x' and `bar_area_width', respectively.
12326 (x_scroll_run): Take account of fringe background extension.
12328 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
12329 Rename local vars `left' and `width' to `bar_area_x' and
12330 `bar_area_width', respectively.
12331 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
12332 background extension.
12334 2011-05-10 Jim Meyering <meyering@redhat.com>
12336 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
12338 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
12340 * image.c (Finit_image_library): Return t for built-in image types,
12341 like pbm and xbm. (Bug#8640)
12343 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
12345 * w32menu.c (set_frame_menubar): Fix submenu allocation.
12347 2011-05-07 Eli Zaretskii <eliz@gnu.org>
12349 * w32console.c (Fset_screen_color): Doc fix.
12350 (Fget_screen_color): New function.
12351 (syms_of_ntterm): Defsubr it.
12353 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
12354 unlink the temporary file if Fcall_process didn't create it in the
12355 first place.
12356 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
12357 child process will be redirected to a file specified with `:file'.
12358 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
12359 cue to call_process_cleanup not to close that handle.
12361 2011-05-07 Ben Key <bkey76@gmail.com>
12363 * makefile.w32-in: The bootstrap-temacs rule now makes use of
12364 one of two shell specific rules, either bootstrap-temacs-CMD or
12365 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
12366 to the previous implementation of the bootstrap-temacs rule.
12367 The bootstrap-temacs-CMD rule is similar to the previous
12368 implementation of the bootstrap-temacs rule except that it
12369 makes use of the ESC_CFLAGS variable instead of the CFLAGS
12370 variable.
12372 These changes, along with some changes to nt/configure.bat,
12373 nt/gmake.defs, and nt/nmake.defs, are required to extend my
12374 earlier fix to add support for --cflags and --ldflags options
12375 that include quotes so that it works whether make uses cmd or
12376 sh as the shell.
12378 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
12380 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
12381 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
12382 is a constant.
12383 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
12384 a string. Handle both cases.
12385 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
12386 (Fdbus_register_method): Use Qinvalid_function.
12388 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
12390 * makefile.w32-in: Update dependencies.
12391 (LISP_H): Add inttypes.h and stdin.h.
12392 (PROCESS_H): Add unistd.h.
12394 2011-05-06 Eli Zaretskii <eliz@gnu.org>
12396 * lread.c: Include limits.h (fixes the MS-Windows build broken by
12397 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
12399 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
12401 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
12403 * term.c (vfatal): Remove stray call to va_end.
12404 It's not needed and the C Standard doesn't allow it here anyway.
12406 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
12407 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
12409 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
12410 bytes.
12412 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
12414 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
12416 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
12418 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
12420 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
12422 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
12423 * charset.c (Fdefine_charset_internal): Don't initialize
12424 charset.code_space[15]. The value was garbage, on hosts with
12425 32-bit int (Bug#8600).
12427 * lread.c (read_integer): Be more consistent with string-to-number.
12428 Use string_to_number to do the actual conversion; this avoids
12429 rounding errors and fixes some other screwups. Without this fix,
12430 for example, #x1fffffffffffffff was misread as -2305843009213693952.
12431 (digit_to_number): Move earlier, for benefit of read_integer.
12432 Return -1 if the digit is out of range for the base, -2 if it is
12433 not a digit in any supported base. (Bug#8602)
12435 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
12437 * dispnew.c (scrolling_window): Return 1 if we scrolled,
12438 to match comment at start of function. This also removes a
12439 GCC warning about overflow in a 32+64-bit port.
12441 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
12443 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
12444 Reported by Stefan Monnier in
12445 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
12446 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
12447 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
12449 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
12450 (EMACS_UINTPTR): Likewise, with uintptr_t.
12452 * lisp.h: Prefer 64-bit EMACS_INT if available.
12453 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
12454 on 32-bit hosts that have 64-bit int, so that they can access
12455 large files.
12456 However, temporarily disable this change unless the temporary
12457 symbol WIDE_EMACS_INT is defined.
12459 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
12461 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
12462 This removes an assumption that EMACS_INT and long are the same
12463 width as pointers. The assumption is true for Emacs porting targets
12464 now, but we want to make other targets possible.
12465 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
12466 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
12467 In the rest of the code, change types of integers that hold casted
12468 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
12469 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
12470 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
12471 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
12472 No need to cast type when ORing.
12473 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
12474 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
12475 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
12476 assume EMACS_INT is the same width as char *.
12477 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
12478 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
12479 Remove no-longer-needed casts.
12480 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
12481 (xg_tool_bar_help_callback, xg_make_tool_item):
12482 Use EMACS_INTPTR to hold an integer
12483 that will be cast to void *; this can avoid a GCC warning
12484 if EMACS_INT is not the same width as void *.
12485 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
12486 * xdisp.c (display_echo_area_1, resize_mini_window_1):
12487 (current_message_1, set_message_1):
12488 Use a local to convert to proper width without a cast.
12489 * xmenu.c (dialog_selection_callback): Likewise.
12491 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
12492 Also, don't assume VALBITS / RAND_BITS is less than 5,
12493 and don't rely on undefined behavior when shifting a 1 left into
12494 the sign bit.
12495 * lisp.h (get_random): Change signature to match.
12497 * lread.c (hash_string): Use size_t, not int, for hash computation.
12498 Normally we prefer signed values; but hashing is special, because
12499 it's better to use unsigned division on hash table sizes so that
12500 the remainder is nonnegative. Also, size_t is the natural width
12501 for hashing into memory. The previous code used 'int', which doesn't
12502 retain enough info to hash well into very large tables.
12503 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
12505 * dbusbind.c: Don't possibly lose pointer info when converting.
12506 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
12507 Use XPNTR rather than XHASH, so that the high-order bits of
12508 the pointer aren't lost when converting through void *.
12510 * eval.c (Fautoload): Don't double-shift a pointer.
12512 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
12514 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
12516 * gnutls.c (DEF_GNUTLS_FN):
12517 * image.c (DEF_IMGLIB_FN): Make function pointers static.
12519 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
12521 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
12522 marker. (Bug#8610)
12524 2011-05-05 Eli Zaretskii <eliz@gnu.org>
12526 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
12527 New version that can reserve upto 2GB of heap space.
12529 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
12531 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
12533 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
12535 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
12536 `gnutls_certificate_set_x509_key_file'.
12538 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
12540 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
12541 Update dependencies.
12543 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
12545 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
12546 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
12547 Remove unused parameter `fildes'.
12548 * process.c (read_process_output, send_process): Don't pass it.
12550 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
12552 Fix previous change: the library cache is defined in w32.c.
12553 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
12554 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
12556 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
12558 Implement dynamic loading of GnuTLS on Windows.
12560 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
12561 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
12562 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
12563 Declare.
12565 * gnutls.c (Qgnutls_dll): Define.
12566 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
12567 (gnutls_*): Declare function pointers.
12568 (init_gnutls_functions): New function to initialize function pointers.
12569 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
12570 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
12571 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
12572 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
12573 (emacs_gnutls_write, emacs_gnutls_read)
12574 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
12575 (Fgnutls_available_p): New function.
12576 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
12577 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.

12582 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
12583 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
12584 (w32_delayed_load): Move to w32.c.
12586 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
12588 * w32.c (QCloaded_from, Vlibrary_cache): Define.
12589 (w32_delayed_load): Move from image.c. When loading a library, record
12590 its filename in the :loaded-from property of the library id.
12591 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
12592 Initialize and staticpro them.
12593 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
12595 * process.c: Include lisp.h before w32.h, not after.
12596 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
12597 instead of gnutls_record_check_pending.
12599 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
12601 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
12603 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
12604 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
12605 as passed in.
12607 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
12609 * xterm.c (x_set_frame_alpha): Do not set property on anything
12610 else than FRAME_X_OUTER_WINDOW (Bug#8608).
12612 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
12614 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
12616 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
12618 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
12619 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

12625 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
12626 (Qgnutls_bootprop_callbacks_verify): Make static.
12628 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
12630 * callproc.c: Indentation fixup.
12632 * sysdep.c (wait_for_termination_1): Make static.
12633 (wait_for_termination, interruptible_wait_for_termination):
12634 Move after wait_for_termination_1.
12636 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
12638 * sysdep.c (interruptible_wait_for_termination): New function
12639 which is like wait_for_termination, but allows keyboard
12640 interruptions.
12642 * callproc.c (Fcall_process): Add (:file "file") as an option for
12643 the STDOUT buffer.
12644 (Fcall_process_region): Ditto.
12646 2011-04-30 Eli Zaretskii <eliz@gnu.org>
12648 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
12649 rather than `XVECTOR (FOO)->size'.
12651 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
12652 inttypes.h, as a gnulib replacement is used if it not available in
12653 system headers.
12655 2011-04-21 Eli Zaretskii <eliz@gnu.org>
12657 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
12658 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
12659 of MOST_POSITIVE_FIXNUM. (Bug#8528)
12661 * coding.c (coding_alloc_by_realloc): Error out if destination
12662 will grow beyond MOST_POSITIVE_FIXNUM.
12663 (decode_coding_emacs_mule): Abort if there isn't enough place in
12664 charbuf for the composition carryover bytes. Reserve an extra
12665 space for up to 2 characters produced in a loop.
12666 (decode_coding_iso_2022): Abort if there isn't enough place in
12667 charbuf for the composition carryover bytes.
12669 2011-04-21 Eli Zaretskii <eliz@gnu.org>
12671 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
12672 aborting when %lld or %lll format is passed.
12673 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
12674 %llo or %llx format is passed. (Bug#8545)
12676 * window.c (window_scroll_line_based): Use a marker instead of
12677 simple variables to record original value of point. (Bug#7952)
12679 * doprnt.c (doprnt): Fix the case where a multibyte sequence
12680 produced by %s or %c overflows available buffer space. (Bug#8545)
12682 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
12684 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
12685 (SIZE_MAX): Move defn after all includes, as they might #define it.
12687 2011-04-28 Juanma Barranquero <lekktu@gmail.com>

12697 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
12699 2011-04-28 Eli Zaretskii <eliz@gnu.org>
12701 * doprnt.c (doprnt): Don't return value smaller than the buffer
12702 size if the message was truncated. (Bug#8545).
12704 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12706 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
12707 (Fx_window_property): #if-0 the whole functions, not just the bodies.
12709 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
12711 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
12713 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
12715 * makefile.w32-in: Update dependencies.
12717 2011-04-27 Eli Zaretskii <eliz@gnu.org>
12719 Improve `doprnt' and its usage. (Bug#8545)
12720 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
12721 `format_end'. Remove support for %l as a conversion specifier.
12722 Don't use xrealloc. Improve diagnostics when the %l size modifier
12723 is used. Update the commentary.
12725 * eval.c (verror): Simplify calculation of size_t.
12727 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
12728 messages.
12730 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
12732 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
12733 change.
12735 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
12737 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
12738 This makes this file independent of the recent pseudovector change.
12740 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
12742 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
12744 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
12745 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
12746 Remove unused local.
12747 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
12749 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
12750 GCC 4.6.0 optimizes based on type-based alias analysis.
12751 For example, if b is of type struct buffer * and v of type struct
12752 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
12753 != &v->size, and therefore "v->size = 1; b->size = 2; return
12754 v->size;" must therefore return 1. This assumption is incorrect
12755 for Emacs, since it type-puns struct Lisp_Vector * with many other
12756 types. To fix this problem, this patch adds a new type struct
12757 vectorlike_header that documents the constraints on layout of vectors
12758 and pseudovectors, and helps optimizing compilers not get fooled
12759 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
12760 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
12761 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
12762 the size member.
12763 (XSETPVECTYPE): Rewrite in terms of new macro.
12764 (XSETPVECTYPESIZE): New macro, specifying both type and size.
12765 This is a bit clearer, and further avoids the possibility of
12766 undesirable aliasing.
12767 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
12768 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
12769 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
12770 since Lisp_Subr is a special case (no "next" field).
12771 (ASIZE): Now uses header.size rather than size.
12772 All previous uses of XVECTOR (foo)->size replaced to use this macro,
12773 to avoid the hassle of writing XVECTOR (foo)->header.size.
12774 (struct vectorlike_header): New type.
12775 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
12776 object, to help avoid aliasing.
12777 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
12778 (SUBRP): Likewise, since Lisp_Subr is a special case.
12779 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
12780 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
12781 (struct Lisp_Hash_Table): Combine first two members into a single
12782 struct vectorlike_header member. All uses of "size" and "next" members
12783 changed to be "header.size" and "header.next".
12784 * buffer.h (struct buffer): Likewise.
12785 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
12786 * frame.h (struct frame): Likewise.
12787 * process.h (struct Lisp_Process): Likewise.
12788 * termhooks.h (struct terminal): Likewise.
12789 * window.c (struct save_window_data, struct saved_window): Likewise.
12790 * window.h (struct window): Likewise.
12791 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
12792 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
12793 * buffer.c (init_buffer_once): Likewise.
12794 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
12795 special case.
12796 * process.c (Fformat_network_address): Use local var for size,
12797 for brevity.
12799 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
12801 Make the Lisp reader and string-to-float more consistent (Bug#8525)
12802 * data.c (atof): Remove decl; no longer used or needed.
12803 (digit_to_number): Move to lread.c.
12804 (Fstring_to_number): Use new string_to_number function, to be
12805 consistent with how the Lisp reader treats infinities and NaNs.
12806 Do not assume that floating-point numbers represent EMACS_INT
12807 without losing information; this is not true on most 64-bit hosts.
12808 Avoid double-rounding errors, by insisting on integers when
12809 parsing non-base-10 numbers, as the documentation specifies.
12810 * lisp.h (string_to_number): New decl, replacing ...
12811 (isfloat_string): Remove.
12812 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
12813 (read1): Do not accept +. and -. as integers; this
12814 appears to have been a coding error. Similarly, do not accept
12815 strings like +-1e0 as floating point numbers. Do not report
12816 overflow for integer overflows unless the base is not 10 which
12817 means we have no simple and reliable way to continue.
12818 Break out the floating-point parsing into a new
12819 function string_to_number, so that Fstring_to_number parses
12820 floating point numbers consistently with the Lisp reader.
12821 (digit_to_number): Move here from data.c. Make it static inline.
12822 (E_CHAR, EXP_INT): Remove, replacing with ...
12823 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
12824 (string_to_number): New function, replacing isfloat_string.
12825 This function checks for valid syntax and produces the resulting
12826 Lisp float number too. Rework it so that string-to-number
12827 no longer mishandles examples like "1.0e+". Use strtoumax,
12828 so that overflow for non-base-10 numbers is reported only when
12829 there's no portable and simple way to convert to floating point.
12831 * textprop.c (set_text_properties_1): Rewrite for clarity,
12832 and to avoid GCC warning about integer overflow.
12834 * intervals.h (struct interval): Use EMACS_INT for members
12835 where EMACS_UINT might cause problems. See
12836 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
12837 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
12838 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
12839 All uses changed.
12840 (offset_intervals): Tell GCC not to worry about length overflow
12841 when negating a negative length.
12843 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
12844 (overrun_check_free): Likewise.
12846 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
12847 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
12848 word size.
12850 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12851 (gnutls_make_error): Rename local to avoid shadowing.
12852 (gnutls_emacs_global_deinit): ifdef out; not used.
12853 (Fgnutls_boot): Use const for pointer to readonly storage.
12854 Comment out unused local. Fix pointer signedness problems.
12856 * lread.c (openp): Don't stuff size_t into an 'int'.
12857 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
12858 about possible signed overflow.
12860 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12861 (GDK_KEY_g): Don't define if already defined.
12862 (xg_prepare_tooltip): Avoid pointer signedness problem.
12863 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
12865 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
12866 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
12868 * xfns.c (Fx_window_property): Simplify a bit,
12869 to make a bit faster and to avoid GCC 4.6.0 warning.
12870 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
12872 * fns.c (internal_equal): Don't assume size_t fits in int.
12874 * alloc.c (compact_small_strings): Tighten assertion a little.
12876 Replace pEd with more-general pI, and fix some printf arg casts.
12877 * lisp.h (pI): New macro, generalizing old pEd macro to other
12878 conversion specifiers. For example, use "...%"pI"d..." rather
12879 than "...%"pEd"...".
12880 (pEd): Remove. All uses replaced with similar uses of pI.
12881 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
12882 * alloc.c (check_pure_size): Don't overflow by converting size to int.
12883 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
12884 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
12885 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
12886 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
12887 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
12888 64-bit hosts.
12889 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
12890 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
12891 * print.c (safe_debug_print, print_object): Likewise.
12892 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
12893 to int.
12894 Use pI instead of if-then-else-abort. Use %p to avoid casts,
12895 avoiding the 0 flag, which is not portable.
12896 * process.c (Fmake_network_process): Use pI to avoid cast.
12897 * region-cache.c (pp_cache): Likewise.
12898 * xdisp.c (decode_mode_spec): Likewise.
12899 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
12900 behavior on 64-bit hosts with printf arg.
12901 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
12902 (x_stop_queuing_selection_requests): Likewise.
12903 (x_get_window_property): Don't truncate byte count to an 'int'
12904 when tracing.
12906 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
12907 here, since it parses constructs like leading '-' and spaces,
12908 which are not wanted; and it overflows with large numbers.
12909 Instead, simply match F[0-9]+, which is what is wanted anyway.
12911 * alloc.c: Remove unportable assumptions about struct layout.
12912 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
12913 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
12914 (allocate_vectorlike, make_pure_vector): Use the new macros,
12915 plus offsetof, to remove unportable assumptions about struct layout.
12916 These assumptions hold on all porting targets that I know of, but
12917 they are not guaranteed, they're easy to remove, and removing them
12918 makes further changes easier.
12920 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
12921 This doesn't fix a bug but makes the code clearer.
12922 (string_overrun_cookie): Now const. Use initializers that
12923 don't formally overflow signed char, to avoid warnings.
12924 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
12925 can cause Emacs to crash when string overrun checking is enabled.
12926 (allocate_buffer): Don't assume sizeof (struct buffer) is a
12927 multiple of sizeof (EMACS_INT); it need not be, if
12928 alignof(EMACS_INT) < sizeof (EMACS_INT).
12929 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
12931 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
12933 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
12935 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
12937 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
12938 supposed to be handshaking. (Bug#8556)
12939 Reported by Paul Eggert <eggert@cs.ucla.edu>.
12941 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
12943 * lisp.h (Qdebug): List symbol.
12944 * eval.c (Qdebug): Restore global linkage.
12945 * keyboard.c (debug-on-event): New variable.
12946 (handle_user_signal): Break into debugger when debug-on-event
12947 matches the current signal symbol.
12949 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
12951 * alloc.c (check_sblock, check_string_bytes)
12952 (check_string_free_list): Convert to standard C.
12954 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
12956 * w32.c (emacs_gnutls_push): Fix typo.
12958 2011-04-25 Eli Zaretskii <eliz@gnu.org>
12960 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
12961 "cast to pointer from integer of different size".
12963 Improve doprnt and its use in verror. (Bug#8545)
12964 * doprnt.c (doprnt): Document the set of format control sequences
12965 supported by the function. Use SAFE_ALLOCA instead of always
12966 using `alloca'.
12968 * eval.c (verror): Don't limit the buffer size at size_max-1, that
12969 is one byte too soon. Don't use xrealloc; instead xfree and
12970 xmalloc anew.
12972 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
12974 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
12975 callbacks stage.
12977 * gnutls.c: Renamed global_initialized to
12978 gnutls_global_initialized. Added internals for the
12979 :verify-hostname-error, :verify-error, and :verify-flags
12980 parameters of `gnutls-boot' and documented those parameters in the
12981 docstring. Start callback support.
12982 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
12983 unless a fatal error occurred. Call gnutls_alert_send_appropriate
12984 on error. Return error code.
12985 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
12986 (emacs_gnutls_read): Likewise.
12987 (Fgnutls_boot): Return handshake error code.
12988 (emacs_gnutls_handle_error): New function.

12992 (emacs_gnutls_push): Likewise.
12994 * w32.c (emacs_gnutls_pull): New function for GnuTLS on Woe32.
12995 (emacs_gnutls_push): Likewise.

12999 * process.c (wait_reading_process_output): Check if GnuTLS
13000 buffered some data internally if no FDs are set for TLS
13001 connections.

13012 commentary.
13014 * textprop.c (syms_of_textprop): Remove dead code.
13015 (copy_text_properties): Delete obsolete commentary about an
13016 interface that was deleted long ago. Fix typos in the description
13017 of arguments.

13020 to changes in oldXMenu/XMenu.h from 2011-04-16.
13021 <menu_help_message, prev_menu_help_message>: Constify.
13022 (IT_menu_make_room): menu->help_text is now `const char **';
13023 adjust.

13029 * xfaces.c <Qunspecified>: Make extern again.
13031 * syntax.c: Include sys/types.h before including regex.h, as
13032 required by POSIX.
13034 * doc.c (get_doc_string): Improve the format passed to `error'.
13036 * doprnt.c (doprnt): Improve commentary.
13038 * term.c (init_tty) [MSDOS]: Fix 1st argument to maybe_fatal.
13040 * Makefile.in (TAGS): Depend on $(M_FILE) and $(S_FILE), and scan
13041 them with etags.
13043 * makefile.w32-in (globals.h): Add a dummy recipe, to make any
13044 changes in globals.h immediately force recompilation.
13045 (TAGS): Depend on $(CURDIR)/m/intel386.h and
13046 $(CURDIR)/s/ms-w32.h.
13047 (TAGS-gmake): Scan $(CURDIR)/m/intel386.h and $(CURDIR)/s/ms-w32.h.
13049 * character.c (Fchar_direction): Function deleted.
13050 (syms_of_character): Don't defsubr it.
13051 <char-direction-table>: Deleted.
13053 2011-04-23 Eli Zaretskii <eliz@gnu.org>
13055 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
13056 * doprnt.c: Include limits.h.
13057 (SIZE_MAX): New macro.
13058 (doprnt): Return a size_t value. 2nd arg is now size_t.
13059 Many local variables are now size_t instead of int or unsigned.
13060 Improve overflow protection. Support `l' modifier for integer
13061 conversions. Support %l conversion. Don't assume an EMACS_INT
13062 argument for integer conversions and for %c.
13064 * lisp.h (doprnt): Restore prototype.
13066 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
13067 $(SRC)/character.h.
13069 * Makefile.in (base_obj): Add back doprnt.o.
13071 * deps.mk (doprnt.o): Add back prerequisites.
13072 (callint.o): Depend on character.h.
13074 * eval.c (internal_lisp_condition_case): Include the handler
13075 representation in the error message.
13076 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
13077 when breaking from the loop.
13079 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
13081 * callint.c (Fcall_interactively): When displaying error message
13082 about invalid control letter, pass the character's codepoint, not
13083 a pointer to its multibyte form. Improve display of the character
13084 in octal and display also its hex code.
13086 * character.c (char_string): Use %x to display the (unsigned)
13087 codepoint of an invalid character, to avoid displaying a bogus
13088 negative value.
13090 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
13091 `error', not SYMBOL_NAME itself.
13093 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
13094 character arguments to `error'.
13096 * charset.c (check_iso_charset_parameter): Fix incorrect argument
13097 to `error' in error message about FINAL_CHAR argument. Make sure
13098 FINAL_CHAR is a character, and use %c when it is passed as
13099 argument to `error'.

13160 * data.c (arith_error): Mark with NO_RETURN if it doesn't return.
13162 * alloc.c (bytes_used_when_full, SPARE_MEMORY, BYTES_USED):
13163 Define only if needed.
13165 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
13166 by pacifying GCC about it. Maybe it's time to retire it?
13167 * xfaces.c (USG, __TIMEVAL__): Likewise.
13169 * dispextern.h (struct redisplay_interface): Rename param
13170 to avoid shadowing.
13171 * termhooks.h (struct terminal): Likewise.
13172 * xterm.c (xembed_send_message): Likewise.
13174 * insdel.c (make_gap_smaller): Define only if
13175 USE_MMAP_FOR_BUFFERS || REL_ALLOC || DOUG_LEA_MALLOC.
13177 * keyboard.c (read_char): Make a var volatile so longjmp won't clobber
13178 it.
13180 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
13181 so that we aren't warned about unused symbols.
13183 * xfns.c (Fx_file_dialog): Rename local to avoid shadowing.
13185 * xdisp.c (x_produce_glyphs): Mark var as initialized (Bug#8512).

13215 only if HAVE_X_WINDOWS && !USE_X_TOOLKIT.
13217 * bitmaps: Change bitmaps from unsigned char back to the X11
13218 compatible char. Avoid the old compiler warnings about
13219 out-of-range initializers by using, for example, '\xab' rather
13220 than 0xab.
13222 * xgselect.c (xgselect_initialize): Check vs interface
13223 even if ! (defined (USE_GTK) || defined (HAVE_GCONF)).
13225 * xmenu.c (xmenu_show): Rename parm to avoid shadowing.
13227 * xterm.c (x_create_toolkit_scroll_bar): Use const * for pointers

13288 * nsfont.m: Fixed bugs in ns_get_family and

13294 deallocate these memory blocks.

13662 alloc.c: Import and export fewer symbols, and remove unused items.
13663 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
13664 is defined.
13665 (suppress_checking): Add EXTERNALLY_VISIBLE attribute, so that
13666 it's not optimized away by whole-program optimization.
13667 (message_enable_multibyte, free_misc): Remove.
13668 (catchlist, handlerlist, mark_backtrace):
13669 Declare only if BYTE_MARK_STACK.
13670 (mark_byte_stack): Likewise, fixing a ifdef-vs-if typo.
13671 * alloc.c (pure): Export only if VIRT_ADDR_VARIES is defined.
13672 (message_enable_multibyte): Remove decl.
13673 (free_misc, interval_free_list, float_block, float_block_index):
13674 (n_float_blocks, float_free_list, cons_block, cons_block_index):
13675 (cons_free_list, last_marked_index):
13676 Now static.
13677 (suppress_checking, die): Define only if ENABLE_CHECKING is defined.
13678 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
13679 (mark_backtrace): Define only if BYTE_MARK_STACK.
13680 * xdisp.c (message_enable_multibyte): Now static.
13682 Declare Lisp_Object Q* variables to be 'static' if not exported.
13683 This makes it easier for human readers (and static analyzers)
13684 to see whether these variables are used from other modules.
13685 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
13686 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
13687 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:
13688 * font.c, frame.c, fringe.c, ftfont.c, image.c, keyboard.c, keymap.c:
13689 * lread.c, macros.c, minibuf.c, print.c, process.c, search.c:
13690 * sound.c, syntax.c, textprop.c, window.c, xdisp.c, xfaces.c, xfns.c:
13691 * xmenu.c, xselect.c:
13692 Declare Q* vars static if they are not used in other modules.
13693 * ccl.h, character.h, charset.h, coding.h, composite.h, font.h:
13694 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
13695 Remove decls of unexported vars.
13696 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
13698 * lisp.h (DEFINE_FUNC): Make sname 'static'.
13700 Make Emacs functions such as Fatom 'static' by default.
13701 This makes it easier for human readers (and static analyzers)
13702 to see whether these functions can be called from other modules.
13703 DEFUN now defines a static function. To make the function external
13704 so that it can be used in other C modules, use the new macro DEFUE.
13705 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
13706 (Finit_image_library):
13707 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
13708 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
13709 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
13710 Remove decls, since these functions are now static.
13711 (Funintern, Fget_internal_run_time): New decls, since these functions
13712 were already external.
13714 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
13715 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:
13716 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, floatfns.c:
13717 * fns.c, font.c, fontset.c, frame.c, image.c, indent.c:
13718 * keyboard.c, keymap.c, lread.c:
13719 * macros.c, marker.c, menu.c, minibuf.c, print.c, process.c, search.c:
13720 * syntax.c, term.c, terminal.c, textprop.c, undo.c:
13721 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
13722 Mark functions with DEFUE instead of DEFUN,
13723 if they are used in other modules.
13724 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
13725 decls for now-static functions.
13726 * buffer.h (Fdelete_overlay): Remove decl.
13727 * callproc.c (Fgetenv_internal): Mark as internal.
13728 * composite.c (Fremove_list_of_text_properties): Remove decl.
13729 (Fcomposition_get_gstring): New forward static decl.
13730 * composite.h (Fcomposite_get_gstring): Remove decl.

13732 * doc.c (Fdocumntation_property): New forward static decl.
13733 * eval.c (Ffetch_bytecode): New forward static decl.
13734 (Funintern): Remove extern decl; now in .h file where it belongs.
13735 * fileio.c (Fmake_symbolic_link): New forward static decl.
13736 * image.c (Finit_image_library): New forward static decl.
13737 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
13738 * intervals.h (Fprevious_property_change):
13739 (Fremove_list_of_text_properties): Remove decls.
13740 * keyboard.c (Fthis_command_keys): Remove decl.
13741 (Fcommand_execute): New forward static decl.
13742 * keymap.c (Flookup_key): New forward static decl.
13743 (Fcopy_keymap): Now static.
13744 * keymap.h (Flookup_key): Remove decl.
13745 * process.c (Fget_process): New forward static decl.
13746 (Fprocess_datagram_address): Mark as internal.
13747 * syntax.c (Fsyntax_table_p): New forward static decl.
13748 (skip_chars): Remove duplicate decl.
13749 * textprop.c (Fprevious_property_change): New forward static decl.
13750 * window.c (Fset_window_fringes, Fset_window_scroll_bars):
13751 Now internal.
13752 (Fset_window_margins, Fset_window_vscroll): New forward static decls.
13753 * window.h (Fset_window_vscroll, Fset_window_margins): Remove decls.
13755 * editfns.c (Fformat): Remove unreachable code.
13757 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
13759 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
13760 change. (Bug#8496)
13762 2011-04-13 Eli Zaretskii <eliz@gnu.org>
13764 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
13765 when at ZV. (Bug#8487)
13767 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
13769 * charset.c (Fclear_charset_maps): Use xfree instead of free.
13770 (Bug#8437)
13771 * keyboard.c (parse_tool_bar_item): Likewise.
13772 * sound.c (sound_cleanup, alsa_close): Likewise.
13773 * termcap.c (tgetent): Likewise.
13774 * xfns.c (x_default_font_parameter): Likewise.
13775 * xsettings.c (read_and_apply_settings): Likewise.
13777 * alloc.c (overrun_check_malloc, overrun_check_realloc)
13778 (overrun_check_free): Protoize.
13780 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
13782 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
13783 since callers should never pass a negative size.
13784 Change the signature to match that of plain 'read' and 'write'; see
13785 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
13786 * lisp.h: Update prototypes of emacs_write and emacs_read.
13788 2011-04-11 Eli Zaretskii <eliz@gnu.org>
13790 * xdisp.c (redisplay_window): Don't try to determine the character
13791 position of the scroll margin if the window start point w->startp
13792 is outside the buffer's accessible region. (Bug#8468)
13794 2011-04-10 Eli Zaretskii <eliz@gnu.org>
13796 Fix write-region and its subroutines for buffers > 2GB.
13797 * fileio.c (a_write, e_write): Modify declaration of arguments and
13798 local variables to support buffers larger than 2GB.
13799 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
13801 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
13802 argument, local variables, and return value.
13804 * lisp.h: Update prototypes of emacs_write and emacs_read.
13806 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
13808 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
13810 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
13812 Fix more problems found by GCC 4.6.0's static checks.
13814 * xdisp.c (vmessage): Use a better test for character truncation.
13816 * charset.c (load_charset_map): <, not <=, for optimization,
13817 and to avoid potential problems with integer overflow.
13818 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
13819 * casetab.c (set_identity, shuffle): Likewise.
13820 * editfns.c (Fformat): Likewise.
13821 * syntax.c (skip_chars): Likewise.
13823 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
13824 This also lets GCC 4.6.0 generate slightly better loop code.
13826 * callint.c (Fcall_interactively): <, not <=, for optimization.
13827 (Fcall_interactively): Count the number of arguments produced,
13828 not the number of arguments given. This is simpler and lets GCC
13829 4.6.0 generate slightly better code.
13831 * ftfont.c: Distingish more carefully between FcChar8 and char.
13832 The previous code passed unsigned char * to a functions like
13833 strlen and xstrcasecmp that expect char *, which does not
13834 conform to the C standard.
13835 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
13836 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
13837 char * when the C standard requires it.
13839 * keyboard.c (read_char): Remove unused var.
13841 * eval.c: Port to Windows vsnprintf (Bug#8435).
13842 Include <limits.h>.
13843 (SIZE_MAX): Define if the headers do not.
13844 (verror): Do not give up if vsnprintf returns a negative count.
13845 Instead, grow the buffer. This ports to Windows vsnprintf, which
13846 does not conform to C99. Problem reported by Eli Zaretskii.
13847 Also, simplify the allocation scheme, by avoiding the need for
13848 calling realloc, and removing the ALLOCATED variable.
13850 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
13852 Remove invocations of doprnt, as Emacs now uses vsnprintf.
13853 But keep the doprint source code for now, as we might revamp it
13854 and use it again (Bug#8435).
13855 * lisp.h (doprnt): Remove.
13856 * Makefile.in (base_obj): Remove doprnt.o.
13857 * deps.mk (doprnt.o): Remove.
13859 error: Print 32- and 64-bit integers portably (Bug#8435).
13860 Without this change, on typical 64-bit hosts error ("...%d...", N)
13861 was used to print both 32- and 64-bit integers N, which relied on
13862 undefined behavior.
13863 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
13864 * lisp.h (error, verror): Mark as printf-like functions.
13865 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
13866 Report overflow in size calculations when allocating printf buffer.
13867 Do not truncate output string at its first null byte.
13868 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
13869 Truncate the output at a character boundary, since vsnprintf does not
13870 do that.
13871 * charset.c (check_iso_charset_parameter): Convert internal
13872 character to string before calling 'error', since %c now has the
13873 printf meaning.
13874 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
13875 overflow when computing char to be passed to 'error'. Do not
13876 pass Lisp_Object to 'error'; pass the integer instead.
13877 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
13878 formatted with plain %d.
13880 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
13882 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
13884 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
13886 * xterm.c (x_catch_errors): Remove duplicate declaration.
13888 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
13890 * xdisp.c, lisp.h (message_nolog): Remove; unused.
13892 2011-04-10 Jim Meyering <meyering@redhat.com>
13894 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
13895 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
13896 return ssize_t not "int", and use size_t as the buffer length.
13897 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
13898 * gnutls.h: Update declarations.
13899 * process.c (read_process_output): Use ssize_t, to match.
13900 (send_process): Likewise.
13902 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
13904 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
13906 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
13908 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
13909 Use unsigned char, to match FcChar8 type definition.
13911 * xterm.c (handle_one_xevent):
13912 * xmenu.c (create_and_show_popup_menu):
13913 * xselect.c (x_decline_selection_request)
13914 (x_reply_selection_request): Avoid type-punned deref of X events.
13916 2011-04-09 Eli Zaretskii <eliz@gnu.org>
13918 Fix some uses of `int' instead of EMACS_INT.
13919 * search.c (string_match_1, fast_string_match)
13920 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
13921 (scan_buffer, find_next_newline_no_quit)
13922 (find_before_next_newline, search_command, Freplace_match)
13923 (Fmatch_data): Make some `int' variables be EMACS_INT.
13925 * xdisp.c (display_count_lines): 3rd argument and return value now
13926 EMACS_INT. All callers changed.
13927 (pint2hrstr): Last argument is now EMACS_INT.
13929 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
13930 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
13931 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
13932 (decode_coding_utf_16, decode_coding_emacs_mule)
13933 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
13934 (decode_coding_ccl, decode_coding_charset)
13935 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
13936 (decode_coding_iso_2022, decode_coding_emacs_mule)
13937 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
13938 <char_offset, last_offset>: Declare EMACS_INT.
13939 (encode_coding_utf_8, encode_coding_utf_16)
13940 (encode_coding_emacs_mule, encode_invocation_designation)
13941 (encode_designation_at_bol, encode_coding_iso_2022)
13942 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
13943 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
13944 Declare EMACS_INT.
13945 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
13946 (encode_invocation_designation): Last argument P_NCHARS is now
13947 EMACS_INT.
13948 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
13949 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
13951 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
13952 All users changed.
13954 * ccl.c (Fccl_execute_on_string): Declare some variables
13955 EMACS_INT.
13957 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
13959 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
13961 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
13963 * process.c (Fformat_network_address): Doc fix.
13965 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
13967 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
13969 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
13971 * keyboard.c (read_char): Call Lisp function help-form-show,
13972 instead of using internal_with_output_to_temp_buffer.
13973 (Qhelp_form_show): New var.
13974 (syms_of_keyboard): Use DEFSYM macro.
13976 * print.c (internal_with_output_to_temp_buffer): Function deleted.
13978 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
13980 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
13982 * process.c (Flist_processes): Remove to Lisp.
13983 (list_processes_1): Delete.
13985 2011-04-06 Eli Zaretskii <eliz@gnu.org>
13987 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
13989 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
13991 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
13993 Fix more problems found by GCC 4.6.0's static checks.
13995 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
13997 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
13999 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
14001 * xdisp.c (vmessage): Mark as a printf-like function.
14003 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
14005 * sound.c (sound_warning): Don't crash if arg contains a printf format.
14007 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
14008 printf-like functions.
14009 (tiff_load): Add casts to remove these marks before passing them
14010 to system-supplied API.
14012 * eval.c (Fsignal): Remove excess argument to 'fatal'.
14014 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
14015 This avoids several warnings with gcc -Wstrict-overflow.
14016 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
14017 directly, rather than having caller test rule sign. This avoids
14018 some unnecessary tests.
14019 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
14020 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
14021 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
14023 * xfont.c (xfont_text_extents): Remove var that was set but not used.
14024 (xfont_open): Avoid unnecessary tests.
14026 * composite.c (composition_gstring_put_cache): Use unsigned integer.
14028 * composite.h, composite.c (composition_gstring_put_cache):
14029 Use EMACS_INT, not int, for length.
14031 * composite.h (COMPOSITION_DECODE_REFS): New macro,
14032 breaking out part of COMPOSITION_DECODE_RULE.
14033 (COMPOSITION_DECODE_RULE): Use it.
14034 * composite.c (get_composition_id): Remove unused local vars,
14035 by using the new macro.
14037 * textprop.c (set_text_properties_1): Change while to do-while,
14038 since the condition is always true at first.
14040 * intervals.c (graft_intervals_into_buffer): Mark var as used.
14041 (interval_deletion_adjustment): Return unsigned value.
14042 All uses changed.
14044 * process.c (list_processes_1, create_pty, read_process_output):
14045 (exec_sentinel): Remove vars that were set but not used.
14046 (create_pty): Remove unnecessary "volatile"s.
14047 (Fnetwork_interface_info): Avoid possibility of int overflow.
14048 (read_process_output): Do adaptive read buffering even if carryover.
14049 (read_process_output): Simplify nbytes computation if buffered.
14051 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
14053 * syntax.c (scan_words): Remove var that was set but not used.
14054 (update_syntax_table): Use unsigned instead of int.
14056 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
14057 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
14058 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
14060 * print.c (print_error_message): Avoid int overflow.
14062 * font.c (font_list_entities): Redo for clarity,
14063 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
14065 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
14066 (font_score): Avoid potential overflow in diff calculation.
14068 * fns.c (substring_both): Remove var that is set but not used.
14069 (sxhash): Redo loop for clarity and to avoid wraparound warning.
14071 * eval.c (funcall_lambda): Rename local to avoid shadowing.
14073 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
14074 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
14075 can always succeed if overflow has undefined behavior.
14077 * search.c (boyer_moore, wordify): Remove vars set but not used.
14078 (wordify): Omit three unnecessary tests.
14080 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.

14109 that are set but not used.
14111 * xfns.c (make_invisible_cursor): Don't return garbage
14112 if XCreateBitmapFromData fails (Bug#8410).
14114 * xselect.c (x_get_local_selection, x_handle_property_notify):

14127 (map_tty_color) [!defined MSDOS]: Likewise.
14129 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
14131 * coding.c: Remove vars that are set but not used.
14132 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
14133 All callers changed.
14134 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):

14141 * print.c (print_object): Remove var that is set but not used.
14143 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
14144 The gnulib version avoids calling malloc in the usual case,
14145 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
14146 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
14147 * filelock.c (current_lock_owner): Likewise.
14148 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.

14150 (emacs_no_realloc_allocator): New static constant.
14151 (emacs_readlink): New function.
14152 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
14153 ../lib/careadlinkat.h.
14155 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
14157 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
14158 first non-nil return value).
14160 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>

14183 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
14185 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
14187 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
14189 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
14190 later (Bug#8403).
14192 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
14194 Add lexical binding.
14196 * window.c (Ftemp_output_buffer_show): New fun.
14197 (Fsave_window_excursion):
14198 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.

14205 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
14206 Mark as dynamic.
14207 (syms_of_lread): Declare `lexical-binding'.
14209 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
14211 * keyboard.c (eval_dyn): New fun.
14212 (menu_item_eval_property): Use it.
14214 * image.c (parse_image_spec): Use Ffunctionp.
14216 * fns.c (concat, mapcar1): Accept byte-code-functions.
14218 * eval.c (Fsetq): Handle lexical vars.
14219 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
14220 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
14221 (FletX, Flet): Obey lexical binding.
14222 (Fcommandp): Handle closures.
14223 (Feval): New `lexical' arg.
14224 (eval_sub): New function extracted from Feval. Use it almost
14225 everywhere where Feval was used. Look up vars in lexical env.
14226 Handle closures.
14227 (Ffunctionp): Move from subr.el.
14228 (Ffuncall): Handle closures.
14229 (apply_lambda): Remove `eval_flags'.
14230 (funcall_lambda): Handle closures and new byte-code-functions.
14231 (Fspecial_variable_p): New function.
14232 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
14233 but without exporting it to Lisp.
14235 * doc.c (Fdocumentation, store_function_docstring):
14236 * data.c (Finteractive_form): Handle closures.
14238 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
14239 interactive spec.
14241 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
14242 New byte-codes.
14243 (exec_byte_code): New function extracted from Fbyte_code to handle new
14244 calling convention for byte-code-functions. Add new byte-codes.
14246 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
14248 * alloc.c (Fmake_symbol): Init new `declared_special' field.
14250 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
14252 * xdisp.c (redisplay_internal): Fix prototype.
14254 2011-03-31 Eli Zaretskii <eliz@gnu.org>
14256 * xdisp.c (SCROLL_LIMIT): New macro.
14257 (try_scrolling): Use it when setting scroll_limit.
14258 Limit scrolling to 100 screen lines.
14259 (redisplay_window): Even when falling back on "recentering",
14260 position point in the window according to scroll-conservatively,
14261 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
14263 (try_scrolling): When point is above the window, allow searching
14264 as far as scroll_max, or one screenful, to compute vertical
14265 distance from PT to the scroll margin position. This prevents
14266 try_scrolling from unnecessarily failing when
14267 scroll-conservatively is set to a value slightly larger than the
14268 window height. Clean up the case of PT below the margin at bottom
14269 of window: scroll_max can no longer be INT_MAX. When aggressive
14270 scrolling is in use, don't let point enter the opposite scroll
14271 margin as result of the scroll.
14272 (syms_of_xdisp) <scroll-conservatively>: Document the
14273 threshold of 100 lines for never-recentering scrolling.
14275 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
14277 * dispextern.h (move_it_by_lines):
14278 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused

14280 (message_log_check_duplicate): Remove parameters `prev_bol' and
14281 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
14282 (redisplay_internal): Remove parameter `preserve_echo_area',
14283 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
14285 * indent.c (Fvertical_motion):
14286 * window.c (window_scroll_pixel_based, Frecenter):
14287 Don't pass `need_y_p' to `move_it_by_lines'.
14289 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
14291 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
14292 steal a few bits to be more compact.

14294 Remove unneeded casts.
14296 * bytecode.c (Fbyte_code): CAR and CDR can GC.

14300 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
14301 binding" message (bug#7967).
14303 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
14305 Fix more problems found by GCC 4.6.0's static checks.
14307 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
14308 Remove unused local var.
14310 * editfns.c (Fmessage_box): Remove unused local var.
14312 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
14313 (note_mode_line_or_margin_highlight, note_mouse_highlight):
14314 Omit unused local vars.
14315 * window.c (shrink_windows): Omit unused local var.
14316 * menu.c (digest_single_submenu): Omit unused local var.
14317 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
14318 Omit unused local var.
14320 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
14321 Don't assume string length fits in int.
14322 (keyremap_step, read_key_sequence): Use size_t for sizes.

14326 instead of alloca (Bug#8344).
14328 * eval.c (Fbacktrace): Don't assume nargs fits in int.
14329 (Fbacktrace_frame): Don't assume nframes fits in int.
14331 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

14338 * cm.c (calccost): Turn while-do into do-while, for clarity.
14340 * keyboard.c (syms_of_keyboard): Use the same style as later
14341 in this function when indexing through an array. This also
14342 works around GCC bug 48267.
14344 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
14346 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
14348 * chartab.c (sub_char_table_ref_and_range): Redo for slight
14349 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
14351 * keyboard.c, keyboard.h (num_input_events): Now size_t.
14352 This avoids undefined behavior on integer overflow, and is a bit
14353 more convenient anyway since it is compared to a size_t variable.
14355 Variadic C functions now count arguments with size_t, not int.
14356 This avoids an unnecessary limitation on 64-bit machines, which
14357 caused (substring ...) to crash on large vectors (Bug#8344).

14367 * fns.c (concat): Likewise.
14368 * frame.c (x_set_frame_parameters): Likewise.
14369 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
14370 0 if not found, not -1. All callers changed.
14372 * alloc.c (garbage_collect): Don't assume stack size fits in int.
14373 (stack_copy_size): Now size_t, not int.
14374 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
14376 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
14378 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
14379 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

14395 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
14396 don't set the hook to nil, but remove the offending function instead.
14397 (Qcommand_hook_internal): Remove, unused.
14398 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
14399 Vcommand_hook_internal.

14540 2011-03-24 Juanma Barranquero <lekktu@gmail.com>
14542 * w32term.c (x_set_glyph_string_clipping):
14543 Don't pass uninitialized region to CombineRgn.
14545 2011-03-23 Juanma Barranquero <lekktu@gmail.com>
14547 * w32fns.c (x_set_menu_bar_lines): Remove unused variable `olines'.

14567 2011-03-23 Julien Danjou <julien@danjou.info>
14569 * term.c (Fsuspend_tty, Fresume_tty):
14570 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
14571 * window.c (temp_output_buffer_show):
14572 * insdel.c (signal_before_change):
14573 * frame.c (Fhandle_switch_frame):
14574 * fileio.c (Fdo_auto_save):
14575 * emacs.c (Fkill_emacs):
14576 * editfns.c (save_excursion_restore):
14577 * cmds.c (internal_self_insert):
14578 * callint.c (Fcall_interactively):
14579 * buffer.c (Fkill_all_local_variables):
14580 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
14581 Use Frun_hooks.
14582 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
14583 unconditionally since it does the check itself.
14585 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
14587 Fix more problems found by GCC 4.5.2's static checks.
14589 * coding.c (encode_coding_raw_text): Avoid unnecessary test
14590 the first time through the loop, since we know p0 < p1 then.
14591 This also avoids a gcc -Wstrict-overflow warning.
14593 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
14594 leading to a memory leak, possible in functions like
14595 load_charset_map_from_file that can allocate an unbounded number
14596 of objects (Bug#8318).
14598 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
14599 that could (at least in theory) be that large.
14601 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
14602 This is less likely to overflow, and avoids undefined behavior if
14603 overflow does occur. All callers changed. Use strtoul to scan
14604 for the unsigned long integer.
14605 (pint2hrstr): Simplify and tune code slightly.
14606 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
14608 * scroll.c (do_scrolling): Work around GCC bug 48228.
14609 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.

14612 This also avoids a warning with gcc -Wstrict-overflow.
14613 (validate_x_resource_name): Simplify count usage.
14614 This also avoids a warning with gcc -Wstrict-overflow.
14616 * fileio.c (Fcopy_file): Report error if fchown or fchmod
14617 fail (Bug#8306).
14619 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
14621 * process.c (Fmake_network_process): Use socklen_t, not int,
14622 where POSIX says socklen_t is required in portable programs.
14623 This fixes a porting bug on hosts like 64-bit HP-UX, where
14624 socklen_t is wider than int (Bug#8277).
14625 (Fmake_network_process, server_accept_connection):
14626 (wait_reading_process_output, read_process_output):
14627 Likewise.
14629 * process.c: Rename or move locals to avoid shadowing.
14630 (list_processes_1, Fmake_network_process):

14636 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
14637 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
14639 Make tparam.h and terminfo.c consistent.
14640 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
14641 Include tparam.h instead, since it declares them.
14642 * cm.h (PC): Remove extern decl; tparam.h now does this.
14643 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
14644 * terminfo.c: Include tparam.h, to check interfaces.
14645 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
14646 (tparam): Adjust signature to match interface in tparam.h;
14647 this removes some undefined behavior. Check that outstring and len
14648 are zero, which they always are with Emacs.
14649 * tparam.h (PC, BC, UP): New extern decls.
14651 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
14652 (xftfont_open): Rename locals to avoid shadowing.
14654 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
14655 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
14656 (OTF_TAG_SYM): Omit macro if not needed.

14664 * xml.c (make_dom): Now static.
14666 * composite.c (composition_compute_stop_pos): Rename local to
14667 avoid shadowing.
14668 (composition_reseat_it): Remove unused locals.
14669 (find_automatic_composition, composition_adjust_point): Likewise.
14670 (composition_update_it): Mark var as initialized.
14671 (find_automatic_composition): Mark vars as initialized,
14672 with a FIXME (Bug#8290).

14676 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
14677 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
14678 (BUF_DEC_POS): Be more systematic about renaming local temporaries
14679 to avoid shadowing.
14681 * textprop.c (property_change_between_p): Remove; unused.
14683 * intervals.c (interval_start_pos): Now static.
14685 * intervals.h (CHECK_TOTAL_LENGTH): Avoid empty "else".

14688 Rename locals to avoid shadowing.
14690 * sound.c (wav_play, au_play, Fplay_sound_internal):
14691 Fix pointer signedness.
14692 (alsa_choose_format): Remove unused local var.
14693 (wav_play): Initialize a variable to 0, to prevent undefined
14694 behavior (Bug#8278).
14696 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
14698 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
14700 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
14701 clobbering (Bug#8298).
14702 * sysdep.c (sys_subshell): Likewise.
14703 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
14705 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
14706 This should get cleaned up, so that child_setup has the
14707 same signature on all platforms.
14709 * callproc.c (call_process_cleanup): Now static.
14710 (relocate_fd): Rename locals to avoid shadowing.
14712 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
14714 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
14715 not to be necessary, and produces flickering.
14717 2011-03-20 Glenn Morris <rgm@gnu.org>
14719 * config.in: Remove file.
14721 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
14723 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
14724 are now in src/globals.h.
14725 (syms_of_minibuf): Remove spurious & from previous change.
14727 2011-03-20 Leo Liu <sdl.web@gmail.com>
14729 * minibuf.c (completing-read-function): New variable.
14730 (completing-read-default): Rename from completing-read.
14731 (completing-read): Call completing-read-function.
14733 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
14735 * xfaces.c (Fx_load_color_file):
14736 Read color file from absolute filename (bug#8250).
14738 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
14740 * makefile.w32-in: Update dependencies.
14742 2011-03-17 Eli Zaretskii <eliz@gnu.org>
14744 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.
14746 2011-03-17 Paul Eggert <eggert@cs.ucla.edu>
14748 Fix more problems found by GCC 4.5.2's static checks.

14751 (sigchld_handler): Now static.
14753 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
14754 That way, the code declares only the vars that it needs.
14755 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
14756 * s/cygwin.h (PTY_ITERATION): Likewise.
14757 * s/darwin.h (PTY_ITERATION): Likewise.

14764 (CONSTANTLIM): Remove; unused.
14765 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
14766 Define only if needed.
14768 * unexelf.c (unexec): Name an expression,
14769 to avoid gcc -Wbad-function-cast warning.
14770 Use a different way to cause a compilation error if anyone uses
14771 n rather than nn, a way that does not involve shadowing.
14772 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
14774 * deps.mk (unexalpha.o): Remove; unused.
14776 New file unexec.h, the (simple) interface for unexec (Bug#8267).
14777 * unexec.h: New file.
14778 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
14779 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
14780 Depend on unexec.h.
14781 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
14782 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
14783 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
14784 Change as necessary to match prototype in unexec.h.
14786 * syntax.c (Fforward_comment, scan_lists): Rename locals to avoid
14787 shadowing.
14788 (back_comment, skip_chars): Mark vars as initialized.

14801 * font.c (font_unparse_fcname): Abort in an "impossible" situation
14802 instead of using an uninitialized var.
14803 (font_sort_entities): Mark var as initialized.
14805 * character.h (FETCH_CHAR_ADVANCE): Rename locals to avoid shadowing.
14807 * font.c (font_unparse_xlfd): Don't mix pointers to variables with
14808 pointers to constants.
14809 (font_parse_fcname): Remove unused vars.
14810 (font_delete_unmatched): Now static.

14825 * eval.c (call_debugger, do_debug_on_call, grow_specpdl): Now static.
14826 (Fdefvar): Rewrite so as not to use empty "else".

14836 Move decls here, to check interfaces.
14837 * process.c (get_operating_system_release): Move decl to lisp.h.
14838 * xrdb.c (get_system_name): Likewise.
14839 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
14840 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
14841 some of which prompt warnings from gcc -Wbad-function-cast.
14842 (Fformat_time_string, Fencode_time, Finsert_char):
14843 (Ftranslate_region_internal, Fformat):
14844 Rename or remove local vars to avoid shadowing.
14845 (Ftranslate_region_internal): Mark var as initialized.
14847 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
14848 avoid shadowing.
14850 * lisp.h (eassert): Check that the argument compiles, even if
14851 ENABLE_CHECKING is not defined.

14862 (Fmake_vector, Fvector, Fmake_byte_code, Fgarbage_collect):
14863 Rename locals to avoid shadowing.
14864 (mark_stack): Move local variables into the #ifdef region where
14865 they're used.
14866 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
14867 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
14868 needed otherwise.
14869 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
14870 (GC_STRING_CHARS): Remove; not used.
14871 (Fmemory_limit): Cast sbrk's returned value to char *.
14873 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
14874 avoids undefined behavior in theory.
14876 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
14878 Use functions, not macros, for up- and down-casing (Bug#8254).
14879 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
14880 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
14881 to use the following functions instead of these macros.
14882 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
14883 EMACS_INT, since callers assume the returned value fits in int.
14884 (upcase1): Likewise, for UPCASE_TABLE.
14885 (uppercasep, lowercasep, upcase): New static inline functions.
14886 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
14887 the race-condition problem in the old DOWNCASE.
14889 * regex.c (CHARSET_LOOKUP_RANGE_TABLE_RAW, POP_FAILURE_REG_OR_COUNT):

14891 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
14892 (regex_compile, re_search_2, re_match_2_internal):
14893 Remove unused local vars.
14894 (FREE_VAR): Rewrite so as not to use empty "else",
14895 which gcc can warn about.
14896 (regex_compile, re_match_2_internal): Mark locals as initialized.
14897 (RETALLOC_IF): Define only if needed.
14898 (WORDCHAR_P): Likewise. This one is never needed, but is used
14899 only in a comment talking about a compiler bug, so put inside
14900 the #if 0 of that comment.
14901 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
14902 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
14903 Remove; unused.
14905 * search.c (boyer_moore): Rename locals to avoid shadowing.
14906 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
14907 (PREV_CHAR_BOUNDARY): Likewise.

14911 * dired.c (compile_pattern): Move decl from here ...
14912 * lisp.h: ... to here, so that it can be checked.
14913 (struct re_registers): New forward decl.
14915 * character.h (INC_POS, DEC_POS): Rename locals to avoid shadowing.
14917 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
14918 All uses changed.
14919 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
14920 Rename locals to avoid shadowing.
14921 (Fvertical_motion): Mark locals as initialized.
14923 * casefiddle.c (casify_object, casify_region): Now static.
14924 (casify_region): Mark local as initialized.
14926 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
14928 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
14929 New macros, so that the caller can use some names other than
14930 gcpro1, gcpro2, etc.
14931 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
14932 of the new macros.
14933 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
14934 argument, for consistency with GCPRO2_VAR, etc: it is now the
14935 prefix of the variable, not the variable itself. All uses
14936 changed.
14937 * dired.c (directory_files_internal, file_name_completion):
14938 Rename locals to avoid shadowing.
14940 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
14941 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
14942 dired.c's scmp function, had undefined behavior.
14943 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
14944 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
14945 * buffer.h: ... to here, because these macros use current_buffer,
14946 and the new implementation with inline functions needs to have
14947 current_buffer in scope now, rather than later when the macros
14948 are used.
14949 (downcase, upcase1): New static inline functions.
14950 (DOWNCASE, UPCASE1): Reimplement using these functions.
14951 This avoids undefined behavior in expressions like
14952 DOWNCASE (x) == DOWNCASE (y), which previously suffered
14953 from race conditions in accessing the global variables
14954 case_temp1 and case_temp2.
14955 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
14956 * lisp.h (case_temp1, case_temp2): Remove their decls.
14957 * character.h (ASCII_CHAR_P): Move from here ...
