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

576 any, in the DEFALT argument into the root of the Emacs build or
577 installation tree, as appropriate.
579 * callproc.c (init_callproc_1): Call decode_env_path instead of
580 doing its equivalent by hand.

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

642 (map_w32_filename): Improve commentary. Simplify switch.
643 (SYMBOLIC_LINK_FLAG_DIRECTORY): Define if not defined in system
644 headers (most versions of MinGW w32api don't).
645 (get_security_info, create_symbolic_link)
646 (get_file_security_desc_by_handle, is_symlink, chase_symlinks):
647 New functions.
648 (sys_access, sys_chmod): Call 'chase_symlinks' to resolve symlinks

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

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

695 * composite.c (COMPOSITE_INLINE):
696 * dispnew.c (DISPEXTERN_INLINE):
697 * sysdep.c (SYSTIME_INLINE):
698 Define to EXTERN_INLINE, so that the corresponding functions
699 are compiled into code.
700 * conf_post.h (INLINE, EXTERN_INLINE, INLINE_HEADER_BEGIN)
701 (INLINE_HEADER_END): New macros.
702 * lisp.h (PSEUDOVECTOR_FLAG): Now a macro as well as a constant,

724 2012-08-01 Paul Eggert <eggert@cs.ucla.edu>
726 Use "ASET (a, i, v)" rather than "AREF (a, i) = v".
727 This how ASET and AREF are supposed to work, and makes
728 it easier to think about future improvements. See
729 <http://lists.gnu.org/archive/html/emacs-devel/2012-08/msg00026.html>.
730 * charset.h (set_charset_attr): New function.

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

1003 Now constants, for GDB, as well as macros, for static initializers.
1004 (CHAR_TABLE_STANDARD_SLOTS, CHAR_TABLE_EXTRA_SLOTS):
1005 Move to after the definition of struct Lisp_Char_Table,
1006 since the former now needs that type defined.

1107 * w32inevt.c: Include w32inevt.h.
1108 (w32_read_console_input): New inline function, calls either
1109 ReadConsoleInputA or ReadConsoleInputW, depending on the value of
1110 w32_console_unicode_input.
1111 (fill_queue): Call w32_read_console_input instead of ReadConsoleInput.
1112 (w32_kbd_patch_key, key_event): Use the codepage returned by

1114 (key_event): use uChar.UnicodeChar only if
1115 w32_console_unicode_input is non-zero.
1117 * w32console.c: Include w32heap.h.

1143 list.
1145 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
1146 enumeration constants, as PURE and HEAP are too general, and clash
1147 with other headers and sources, such as gmalloc.c and the
1148 MS-Windows system headers. All users changed.
1150 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
1152 Revert last save_excursion_save and save_excursion_restore changes.
1153 * alloc.c, editfns.c, marker.c, lisp.h: Revert.

1163 2012-07-27 Paul Eggert <eggert@cs.ucla.edu>
1165 Improve GDB symbol export (Bug#12036).
1166 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
1167 arms of an 'if', not using conditional expressions; otherwise GDB
1168 complains about the types in the unevaluated arm when the argument
1169 is an integer literal.
1170 (xgetint): Simplify expression.
1171 * alloc.c (gdb_make_enums_visible): New constant. This ports to
1172 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
1173 Zaretskii in <http://bugs.gnu.org/12036#13>.
1174 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
1175 needed now that we have gdb_make_enums_visible.
1176 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
1177 (enum enum_USE_LSB_TAG):
1178 New enum types, packaging up enums that need to be exported to GDB.

1196 * xdisp.c (syms_of_xdisp): Likewise.
1197 * xfns.c (syms_of_xfns): Likewise.
1199 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
1201 Fast save_excursion_save and save_excursion_restore.
1202 * lisp.h (struct Lisp_Excursion): New data type.
1203 (PVEC_EXCURSION): New pseudovector type.
1204 (XEXCURSION, XSETEXCURSION, EXCURSIONP): Convenient macros
1205 to deal with it. Adjust comments.

1216 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
1218 Fix export of symbols to GDB (Bug#12036).
1219 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
1220 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
1221 emacs.c, as this is a more-suitable home. Had this been done earlier
1222 the fix for 12036 would have avoided some of the problems noted in
1223 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
1224 would have been more obvious.
1225 * emacs.c: Do not include <verify.h>; no longer needed.
1226 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
1227 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
1228 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
1229 Remove; now done in lisp.h.
1230 * lisp.h (PUBLISH_TO_GDB): New macro.

1232 (DATA_SEG_BITS): Use it.
1233 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
1234 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
1235 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
1236 not be usable in #if. This simplifies things.
1238 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
1240 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
1242 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
1244 Simplify export of symbols to GDB (Bug#12036).
1245 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
1246 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
1247 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
1248 Adjust to changes in lisp.h and emacs.c, by using
1249 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
1250 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
1251 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
1252 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
1253 instead of gdb_valbits.
1254 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
1255 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
1256 instead of gdb_array_mark_flag.
1257 (xboolvector): Get size from $->size, not $->header.size.
1258 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
1259 (xreload, hook-run, hookpost-run): Remove.
1260 * emacs.c: Include <verify.h>.
1261 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
1262 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
1263 Remove.
1264 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
1265 (gdb_USE_LSB_TAG): New enum constants.
1266 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
1267 Also define these as enum constants, so they're visible to GDB.
1268 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
1269 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
1270 as constants, so they're visible to GDB.
1271 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
1272 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
1273 Now enum constants, not macros, so they're visible to GDB.
1274 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
1275 more convenient now. All uses changed.
1276 (VALMASK) [USE_LSB_TAG]: Also define in this case.
1277 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.
1279 2012-07-26 Dmitry Antipov <dmantipov@yandex.ru>
1281 Explicitly free restriction data that are not needed anymore.
1282 * editfns.c (save_restriction_restore): Free restriction data.
1284 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
1286 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
1287 add argument, tune behavior, and adjust all callers.
1289 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
1291 Use typedef for EMACS_INT, EMACS_UINT.
1292 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
1293 than macros. This simplifies debugging in the usual case, since
1294 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
1295 and it allows expressions involving EMACS_INT casts.
1296 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
1298 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>
1300 * nsterm.m (ns_read_socket): Return early if there is a modal
1301 window (Bug#12043).

1306 that FOCUS-FRAME can be omitted.
1308 2012-07-25 Dmitry Antipov <dmantipov@yandex.ru>
1310 Adjust buffer text indirection counters at the end of Fkill_buffer.
1311 * buffer.c (Fkill_buffer): Adjust indirection counters when the
1312 buffer is definitely dead. This should really fix an issue reported
1313 by Christoph Scholtes again. (Bug#12007).
1314 (init_buffer_once): Initialize indirection counters of
1315 buffer_defaults and buffer_local_symbols (for sanity and safety).
1317 2012-07-24 Eli Zaretskii <eliz@gnu.org>
1319 * xdisp.c (init_iterator): Don't compute dimensions of truncation
1320 and continuation glyphs on tooltip frames, leave them at zero.
1321 Avoids continued lines in tooltips. (Bug#11832)
1323 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
1325 Simplify copy_overlay.
1326 * buffer.c (copy_overlay): Simplify. Use build_marker.

1332 or invalid. (Bug#12025)
1334 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
1335 it signals an error when a tooltip frame is being created.
1337 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
1339 Cleanup miscellaneous objects allocation and initialization.
1340 * alloc.c (allocate_misc): Change to static. Add argument to
1341 specify the subtype. Adjust comment and users.
1342 (build_overlay): New function.
1343 * buffer.c (copy_overlays, Fmake_overlay): Use it.
1344 * lisp.h (struct Lisp_Overlay): Remove obsolete comment.
1345 (allocate_misc): Remove prototype.
1346 (build_overlay): Add prototype.
1348 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
1350 Swap buffer text indirection counters in Fbuffer_swap_text.
1351 * buffer.c (Fbuffer_swap_text): Swap indirections too.
1352 This avoids crash reported by Christoph Scholtes at
1353 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
1355 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
1357 * nsmenu.m (Popdown_data): New struct.
1358 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
1359 free Popdown_data.
1360 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
1361 (initWithContentRect): Make imgView and contentView non-static
1362 and autorelease them. Also autorelease img and matrix (Bug#12005).
1363 (dealloc): Remove (Bug#12005).

2116 The functional style also makes code easier to read and maintain.
2117 * systime.h: Include <sys/time.h> on all hosts, not just if
2118 WINDOWSNT, since 'struct timeval' is needed in general.

2134 (add_emacs_time, sub_emacs_time): New functions.
2135 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.

2152 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
2153 (menu_separator_name_p):
2154 * nsmenu.m (ns_update_menubar):
2155 Prefer memcmp to strncmp when either will do.
2156 * nsterm.m: Include <ftoastr.h>.
2157 (ns_get_color):
2158 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
2159 Prefer snprintf to strncpy.
2160 * nsterm.m (ns_term_init):
2161 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
2162 * nsterm.m (ns_term_init):
2163 Avoid the need for strncpy, by using build_string or
2164 make_unibyte_string directly. Use dtoastr, not snprintf.
2165 * process.c (Fmake_network_process): Diagnose service names that
2166 are too long, rather than silently truncating them or creating
2167 non-null-terminated names.

2184 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
2185 where argument type is known to be a Lisp_Cons.

2201 the function is called with compile-time constant argument.
2202 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
2203 argument, adjust users accordingly. Use build_pure_c_string where
2204 appropriate.

2237 We include usg5-4-common.h, which defines them both.
2239 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
2240 O_RDONLY already includes it).
2242 Stop ns builds setting the EMACSLOADPATH environment variable.
2243 * nsterm.m (ns_load_path): Rename from ns_init_paths.
2244 Now it does not set EMACSLOADPATH, just returns the load-path string.
2245 * nsterm.h: Update accordingly.
2246 * lread.c [HAVE_NS]: Include nsterm.h.
2247 (init_lread) [HAVE_NS]: Use ns_load_path.

2250 2012-07-09 Glenn Morris <rgm@gnu.org>
2252 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
2253 since the included bsd-common.h does so.
2255 Stop ns builds setting the EMACSPATH environment variable.
2256 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
2257 (ns_init_paths): Do not set EMACSPATH.
2258 * nsterm.h (ns_exec_path): Add it.
2259 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
2260 Use ns_exec_path.
2262 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
2264 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
2266 * process.c (wait_reading_process_output): 'waitchannels' was unset
2267 when read_kbd || !NILP (wait_for_cell); fix this.
2269 Add GCC-style 'const' attribute to functions that can use it.
2270 * character.h (char_resolve_modifier_mask):
2271 * keyboard.h (make_ctrl_char):
2272 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
2273 (init_character_once, next_almost_prime, init_fns, init_image)
2274 (flush_pending_output, init_sound):
2275 * mem-limits.h (start_of_data):
2276 * menu.h (finish_menu_items):
2277 Add ATTRIBUTE_CONST.
2278 * emacs.c (DEFINE_DUMMY_FUNCTION):
2279 Declare the dummy function with ATTRIBUTE_CONST.
2280 * lisp.h (Fbyteorder, Fmax_char, Fidentity):
2281 Add decls with ATTRIBUTE_CONST.
2283 Minor improvements to make_formatted_string.
2284 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
2285 where int is good enough, as vsprintf returns an int.
2286 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
2288 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
2290 Use make_formatted_string to avoid double length calculation.
2291 * lisp.h (make_formatted_string): New prototype.
2292 * alloc.c (make_formatted_string): New function.
2293 * buffer.c (Fgenerate_new_buffer_name): Use it.

2298 (x_report_frame_params): Likewise.
2299 * image.c (gs_load): Likewise.
2300 * minibuf.c (get_minibuffer): Likewise.

2313 (init_callproc_1, init_callproc) [HAVE_NS]: Use ns_etc_directory.
2315 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
2317 Move marker debugging code under MARKER_DEBUG.
2318 * marker.c (MARKER_DEBUG): Move marker debugging code under
2319 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
2320 for bootstrap with --enable-checking (~3x slowdown reported
2321 by Juanma Barranquero <lekktu@gmail.com>).
2322 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
2324 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
2326 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
2327 See <http://bugs.gnu.org/11825#29>.
2329 2012-07-08 Eli Zaretskii <eliz@gnu.org>
2331 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
2332 has no font, use the frame's font. (Bug#11813)
2333 (display_line): Add commentary about displaying truncation glyphs
2334 on GUI frames.
2335 (produce_special_glyphs): Move here from term.c.
2337 * term.c (produce_special_glyphs): Move to xdisp.c.
2339 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
2340 section.
2342 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
2344 * xdisp.c (display_line): Avoid warning about implicit declaration
2345 of FRAME_FONT.
2347 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
2349 * lisp.h: Remove empty conditional.
2351 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
2353 * lread.c (load_path_check): Now static.
2355 Fix some minor --with-ns problems found by static checking.
2356 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
2357 (x_set_font) [!HAVE_X_WINDOWS]:
2358 * image.c (xpm_load_image) [HAVE_NS]:
2359 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
2360 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
2361 Remove unused local.
2362 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
2363 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
2364 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
2365 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
2366 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
2367 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
2368 Fix pointer signedness problem.
2369 * xfaces.c (FRAME_X_FONT_TABLE):
2370 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
2372 2012-07-07 Glenn Morris <rgm@gnu.org>
2374 * lread.c (load_path_check): New function, split from init_lread.
2375 (init_lread): Reorganize. Motivation:
2376 If EMACSLOADPATH is set, check/warn about that rather than the
2377 defaults, which we are not going to use. Hence we can remove
2378 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
2379 Don't warn if site-lisp directories are missing.
2380 If not installed, start from a blank load-path, since
2381 PATH_LOADSEARCH refers to the eventual installation directories.
2383 2012-07-07 Eli Zaretskii <eliz@gnu.org>
2385 Support truncation and continuation glyphs on GUI frames, when
2386 fringes are disabled. (Bug#11832)
2387 * xdisp.c (init_iterator): Get dimensions of truncation and
2388 continuation glyphs even if on GUI frames.
2389 Adjust it->last_visible_x on GUI frames when the left or right fringes,
2390 or both, are absent.
2391 (start_display, move_it_in_display_line_to): Handle the case of a
2392 GUI frame without a fringe to display continuation or truncation
2393 glyphs.
2394 (insert_left_trunc_glyphs): Support GUI frames: make sure
2395 truncation glyphs overwrite enough glyphs from the current line to
2396 have sufficient space in pixels.
2397 (display_line): Support truncation and continuation glyphs on GUI
2398 frames. If some spare pixels are left on the line after inserting
2399 the truncation glyphs, fill that space with a stretch glyph of a
2400 suitably computed width.
2402 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
2403 produce_glyphs, to support GUI sessions.
2405 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
2407 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
2409 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
2411 Do not require float-time's arg to fit in time_t (Bug#11825).
2412 This works better on hosts where time_t is unsigned, and where
2413 float-time is applied to the (negative) difference between two times.
2414 * editfns.c (decode_time_components): Last arg is now double *,
2415 not int *, and means to store all the result as a double, without
2416 worrying about whether the seconds part fits in time_t.
2417 All callers changed.
2418 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
2419 All callers changed.
2420 (Ffloat_time): Do not fail merely because the specified time falls
2421 outside of time_t range.
2423 2012-07-07 Glenn Morris <rgm@gnu.org>
2425 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):
2426 * s/hpux10-20.h (HAVE_RINT, HAVE_RANDOM):
2427 * s/unixware.h (HAVE_GETWD): Move undefs to configure (effectively).
2429 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
2431 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
2432 Update dependencies.
2434 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
2436 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
2438 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
2439 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
2440 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
2441 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
2442 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
2443 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
2445 * xfont.c (compare_font_names): Redo to omit the need for casts.
2447 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
2449 * xfns.c (Fx_change_window_property): Doc fix.
2450 * w32fns.c (Fx_change_window_property): Doc fix.
2452 * w32fns.c (Fx_window_property): Accept the same arguments as the
2453 X Windows version. Doc fix.
2454 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
2456 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
2457 Eli Zaretskii <eliz@gnu.org>
2459 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
2460 Windows-specific code from nt/config.nt moved here.
2461 Obsolete settings removed.
2463 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
2465 * process.c: Avoid unnecessary calls to gettime.
2466 (wait_reading_process_output): Don't get the time of day
2467 when gobbling data immediately and not waiting, as there's no need
2468 for it in that case. This removes a FIXME.
2470 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
2472 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
2473 is defined (Bug#11768).
2475 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2477 Fix marker debugging code.
2478 * marker.c (byte_char_debug_check): Do not perform the check
2479 if buffer is not multibyte.
2480 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
2481 Call byte_char_debug_check with correct arguments.
2483 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2485 Compile marker debugging code only if ENABLE_CHECKING is defined.
2486 * marker.c (byte_char_debug_check, count_markers):
2487 Use only if ENABLE_CHECKING is defined.
2488 (byte_debug_flag): Remove.
2489 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
2490 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
2492 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2494 Avoid code repetition in marker-related functions.
2495 * marker.c (attach_marker): New function.
2496 (Fset_marker, set_marker_restricted, set_marker_both)
2497 (set_marker_restricted_both): Use it.
2498 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
2499 Consistently rename charno to charpos.
2500 (marker_position): Add eassert.
2501 (marker_byte_position): Convert to eassert.
2503 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>

2517 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
2518 (save_restriction_save): Use build_marker.
2519 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
2520 * window.c (save_window_save): Likewise.
2522 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
2524 Do not use Fdelete_overlay in delete_all_overlays
2525 to avoid redundant calls to unchain_overlay.
2526 * buffer.c (drop_overlay): New function.
2527 (delete_all_overlays, Fdelete_overlay): Use it.
2528 * minibuf.c (get_minibuffer): Fix comment.
2530 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
2532 Port to OpenBSD 5.1 amd64.
2533 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
2534 This is needed for OpenBSD, and should be harmless on all BSD systems.
2535 Also, include <sys/sysctl.h>, as it should be available on all
2536 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
2537 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
2538 use p_pid member, not kp_proc.pid.
2540 2012-07-06 Glenn Morris <rgm@gnu.org>
2542 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
2544 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
2546 More xmalloc and related cleanup.
2547 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:
2548 * callproc.c, charset.c, coding.c, composite.c, data.c, dispnew.c:
2549 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, fns.c:

2555 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
2556 * xterm.c:
2557 Omit needless casts involving void * pointers and allocation.
2558 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
2559 as the former is more robust if P's type is changed.
2560 Prefer xzalloc to xmalloc + memset 0.
2561 Simplify malloc-or-realloc to realloc.
2562 Don't worry about xmalloc returning a null pointer.
2563 Prefer xstrdup to xmalloc + strcpy.
2564 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
2565 growing it.
2566 * keyboard.c (apply_modifiers_uncached): Prefer local array to
2567 alloca of a constant.
2569 2012-07-05 Eli Zaretskii <eliz@gnu.org>
2571 * xdisp.c (display_line): Fix horizontal pixel coordinates when
2572 hscroll is larger than the line width. Fixes long and futile
2573 looping inside extend_face_to_end_of_line (on a TTY) producing
2574 glyphs that are not needed and thrown away.
2576 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
2578 * marker.c (set_marker_restricted_both): Simplify by using
2579 clip_to_bounds.

2592 followed by gtk_box_set_homogeneous (Bug#11768).
2593 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
2594 (update_theme_scrollbar_width, xg_create_scroll_bar):
2595 Use gtk_scrollbar_new (Bug#11768).
2596 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
2597 (is_box_type): New function (Bug#11768).
2598 (xg_tool_item_stale_p): Call is_box_type.
2599 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
2600 with default display (Bug#11768).
2602 2012-07-05 Eli Zaretskii <eliz@gnu.org>
2604 * xdisp.c (window_hscroll_limited): New function.
2605 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
2606 coordinates when window's hscroll is set to insanely large
2607 values. (Bug#11857)
2609 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
2611 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.
2612 ($(BLD)/terminal.$(O), $(BLD)/syntax.$(O)): Update dependencies.
2614 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>

2670 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
2672 * fileio.c (time_error_value): Check the right error number.
2673 Problem reported by Troels Nielsen in
2674 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
2676 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2678 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
2679 This should be fixed in a better way; see Eli Zaretskii in
2680 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
2681 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
2683 * fileio.c (time_error_value): Rename from special_mtime.
2684 The old name's problems were noted by Eli Zaretskii in
2685 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
2687 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
2688 This variable's comment says Emacs needs at least one GDB-visible
2689 symbol of type enum pvec_type, to work around GDB problems.
2690 The symbol's value doesn't matter.
2692 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
2693 that causes compilation to fail on pre-C99 compilers.
2695 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
2697 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
2698 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
2700 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2702 * buffer.c (init_buffer_once): Fix initialization of
2703 headers for buffer_defaults and buffer_local_symbols.

2708 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
2709 * lisp.h (enum pvec_type): Use fewer bits.
2710 (PSEUDOVECTOR_SIZE_BITS): New constant.
2711 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
2712 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
2713 change in pvec_type.
2714 (PSEUDOVECTOR_TYPEP): New macro.
2715 (TYPED_PSEUDOVECTORP): Use it.
2716 * fns.c (internal_equal): Adapt code to extract pvectype.

2720 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
2721 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.

2723 abusing vector->header.next.nbytes.
2724 (live_vector_p): Use PVEC_TYPE.
2725 (mark_object): Adapt code to extract pvectype. Use switch.
2727 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2729 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
2730 Tighten new eassert a bit.
2732 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2734 Fix compilation with --enable-gcc-warnings and -O1
2735 optimization level.
2736 * doprnt.c (doprnt): Change type of tem to int, initialize
2737 to avoid compiler warning. Add eassert.
2738 * search.c (simple_search): Initialize match_byte to avoid
2739 compiler warning. Add eassert.
2741 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2743 Avoid weird behavior with large horizontal scrolls.
2744 Without this change, for example, large hscroll values would
2745 mess up Emacs's display on Fedora 15 x86, presumably due to
2746 overflows in int calculations in the display code.
2747 Also, if buffers had long lines, Emacs would freeze.
2748 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
2749 (set_window_hscroll): New function, containing the old guts of
2750 Fset_window_hscroll. Return the clipped value.
2751 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
2752 This avoids the need to check against PTRDIFF_MAX.
2754 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
2756 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
2758 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
2760 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
2762 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
2763 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
2764 since GCC 4.4.6 issues a bogus warning for them.
2766 Fix bugs in file timestamp newness comparisons.
2767 * fileio.c (Ffile_newer_than_file_p):
2768 * lread.c (Fload): Use full timestamp resolution of files,
2769 not just the 1-second resolution, so that files that are only
2770 slightly newer still count as newer.
2771 * fileio.c (Ffile_newer_than_file_p): Don't assume file
2772 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
2774 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
2776 * fileio.c: Improve handling of file time marker. (Bug#11852)
2777 (special_mtime): New function.
2778 (Finsert_file_contents, Fverify_visited_file_modtime):
2779 Use it to set special mtime values consistently.
2781 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
2783 * fileio.c (Finsert_file_contents): Properly handle st_mtime
2784 marker for non-existing file. (Bug#11852)
2786 2012-07-03 Glenn Morris <rgm@gnu.org>
2788 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
2789 and did not make it into globals.h).
2791 2012-07-03 Tom Tromey <tromey@redhat.com>
2793 * window.c (Fset_window_margins, Fset_window_fringes)
2794 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
2795 * textprop.c (Fprevious_property_change): No longer static.
2796 * syntax.c (Fsyntax_table_p): No longer static.
2797 * process.c (Fget_process, Fprocess_datagram_address): No longer
2798 static.
2799 * keymap.c (Flookup_key, Fcopy_keymap): No longer static.
2800 * keyboard.c (Fcommand_execute): No longer static.
2801 Remove EXFUN.
2802 * insdel.c (Fcombine_after_change_execute): No longer static.

2818 * intervals.h: Remove EXFUNs.
2819 * fontset.h: Remove EXFUN.
2820 * font.h: Remove EXFUNs.
2821 * dosfns.c (system_process_attributes): Remove EXFUN.
2822 * keymap.h: Remove EXFUNs.
2823 * lisp.h: Remove EXFUNs.
2824 * w32term.h: Remove EXFUNs.
2825 * window.h: Remove EXFUNs.
2826 * xsettings.h: Remove EXFUN.
2827 * xterm.h: Remove EXFUN.
2829 2012-07-03 Glenn Morris <rgm@gnu.org>
2831 * lisp.h (Frandom): Make it visible to C.
2832 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
2833 buffer for invisible buffers. (Bug#1229)
2835 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2837 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
2838 values which aren't power of 2.
2839 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.
2840 Verify it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
2841 accordingly.
2843 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
2845 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
2847 * alloc.c (mark_object): Revert part of last patch to use `switch'.
2849 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2851 * alloc.c (allocate_vector_block): Remove redundant
2852 calls to mallopt if DOUG_LEA_MALLOC is defined.
2853 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
2854 avoid calls to mallopt if zero_vector is returned.
2856 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2858 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
2859 is enabled, avoid dereferencing NULL current_sblock if
2860 running undumped.
2862 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
2864 Cleanup basic buffer management.
2865 * buffer.h (struct buffer): Change layout to use generic vector
2866 marking code. Fix some comments. Change type of 'clip_changed'
2867 to bitfield. Remove unused #ifndef old.
2868 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
2869 (GET_OVERLAYS_AT): Fix indentation.
2870 (for_each_per_buffer_object_at): New macro.
2871 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)

2873 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
2874 * alloc.c (allocate_buffer): Adjust to match new layout of
2875 struct buffer. Fix comment.
2876 (mark_overlay): New function.
2877 (mark_buffer): Use it. Use mark_vectorlike to mark normal
2878 Lisp area of struct buffer.
2879 (mark_object): Use it. Adjust marking of misc objects
2880 and related comments.
2882 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
2884 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
2885 wrapper that is not needed because the wrapped code is a no-op (zero
2886 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
2887 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
2889 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
2891 * alloc.c (mark_buffer): Simplify. Remove prototype.
2892 (mark_object): Add comment. Reorganize marking of vector-like
2893 objects. Use CHECK_LIVE for all vector-like objects except buffers
2894 and subroutines when GC_CHECK_MARKED_OBJECTS is defined.
2895 Avoid redundant calls to mark_vectorlike for bool vectors.
2897 2012-06-30 Glenn Morris <rgm@gnu.org>
2899 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
2901 * epaths.in (PATH_SITELOADSEARCH): New.
2902 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
2903 This is rather than relying on --enable-locallisppath elements
2904 having "site-lisp" in their names. (Bug#10208#25, 11658)
2906 2012-06-30 Eli Zaretskii <eliz@gnu.org>
2908 * w32proc.c (sys_select): Accept and ignore one more argument.
2910 * w32.c (emacs_gnutls_pull): Call select with one more argument.
2912 * sysselect.h [DOS_NT]: Don't include sys/select.h.
2913 (pselect) [!MS_DOS]: Redirect to sys_select.
2915 * sysdep.c: Don't include dos.h and dosfns.h.
2917 * process.c (sys_select):
2918 * msdos.c (sys_select): Accept one more argument and ignore it.
2920 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
2921 adapt data types and code to that.
2923 * dosfns.c:
2924 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
2925 which clashes with the gnulib function of the same name.
2927 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
2929 * font.c (font_style_to_value, font_style_symbolic)
2930 (font_prop_validate_style): Add type checks for values in
2931 font_style_table.
2933 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
2934 argument.
2935 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
2936 uses.
2938 2012-06-29 Eli Zaretskii <eliz@gnu.org>
2940 * xdisp.c (try_window_id): Undo last change.
2942 * w32.c (getwd): Adjust commentary about startup_dir.
2943 (init_environment): Always call sys_access, even in non-MSVC
2944 builds. Don't chdir to the directory of the Emacs executable.
2945 This undoes code from 1997 which was justified by the need to
2946 "avoid conflicts when removing and renaming directories". But its
2947 downside was that every relative file name was being interpreted
2948 relative to the directory of the Emacs executable, which can never
2949 be TRT. In particular, it broke sys_access when called with
2950 relative file names.
2951 (sys_access): Map GetLastError to errno.
2953 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2955 * window.h (struct window): Change type of 'fringes_outside_margins'
2956 to bitfield. Fix comment. Adjust users accordingly.
2957 (struct window): Change type of 'window_end_bytepos' to ptrdiff_t.
2958 Adjust comment.
2959 * xdisp.c (try_window_id): Change type of 'first_vpos' and 'vpos'
2960 to ptrdiff_t.
2962 2012-06-29 Andreas Schwab <schwab@linux-m68k.org>
2964 * gnutls.c (emacs_gnutls_handshake):
2965 Add QUIT to make the loop interruptible.
2967 2012-06-29 Glenn Morris <rgm@gnu.org>
2969 * charset.c (init_charset): Make lack of etc/charsets fatal.
2971 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2973 * editfns.c (region_limit): Fix type mismatch.
2975 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>
2977 * nsfns.m: Fix GLYPH_DEBUG usage assuming that it may be
2978 undefined. Convert from xassert to eassert.
2979 * nsmenu.m: Convert from xassert to eassert.
2980 * nsterm.m: Likewise.
2982 2012-06-28 Stefan Monnier <monnier@iro.umontreal.ca>

2986 2012-06-28 Paul Eggert <eggert@cs.ucla.edu>
2988 Avoid integer overflow on scroll-left and scroll-right.
2989 * window.c (HSCROLL_MAX): New macro.
2990 (Fscroll_left, Fscroll_right): Avoid undefined behavior on integer
2991 overflow when requested scroll falls outside ptrdiff_t range.
2993 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
2995 * window.h (struct window): Change type of 'hscroll',
2996 'min_hscroll' and 'last_point' from Lisp_Object to ptrdiff_t,
2997 'last_modified' and 'last_overlay_modified' to EMACS_INT.
2998 Adjust users accordingly.
2999 * xdisp.c (try_cursor_movement): Replace type check with eassert.
3000 * window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'
3001 from EMACS_INT to ptrdiff_t.
3002 (make_window): Omit redundant initialization.
3004 2012-06-28 Juanma Barranquero <lekktu@gmail.com>
3006 * makefile.w32-in ($(BLD)/regex.$(O)): Update dependencies.
3008 2012-06-28 Dmitry Antipov <dmantipov@yandex.ru>
3010 * window.h (struct window): Change type of 'use_time' and

3019 * dispextern.h (GLYPH_DEBUG): Now defined in config.h if
3020 enabled with --enable-checking=[all,glyphs] configure option.
3021 Fix GLYPH_DEBUG usage assuming that it may be undefined,
3022 adjust comments accordingly.
3023 * dispnew.c: Fix GLYPH_DEBUG usage assuming that it may be

3064 2012-06-27 Stefan Monnier <monnier@iro.umontreal.ca>
3066 * fns.c (maybe_resize_hash_table): Output message when growing the
3067 purify-hashtable.
3069 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
3071 * alloc.c (allocate_string_data): Remove dead code.
3072 * xsettings.c (XSETTINGS_FONT_NAME): Move under HAVE_XFT to
3073 avoid GCC warning about unused macro.
3075 2012-06-27 Dmitry Antipov <dmantipov@yandex.ru>
3077 * alloc.c (allocate_string): Omit intervals initialization.
3078 * alloc.c (make_uninit_multibyte_string): Initialize intervals
3079 as in make_pure_string and make_pure_c_string.

3135 * alloc.c: Remove build_string.
3136 * lisp.h: Define build_string as static inline. This provides
3137 a better opportunity to optimize away calls to strlen when the
3138 function is called with compile-time constant argument.
3139 * image.c (imagemagick_error): Convert to build_string.
3140 * w32proc.c (sys_spawnve): Likewise.

3143 2012-06-26 Paul Eggert <eggert@cs.ucla.edu>
3145 Use sprintf return value instead of invoking strlen on result.
3146 In the old days this wasn't portable, since some sprintf
3147 implementations returned char *. But they died out years ago and
3148 Emacs already assumes sprintf returns int.
3149 Similarly for float_to_string.
3150 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.
3151 * ccl.c (ccl_driver):
3152 * character.c (string_escape_byte8):

3155 * print.c (print_object):
3156 * xdisp.c (message_dolog):
3157 * xfns.c (syms_of_xfns):
3158 Use sprintf or float_to_string result to avoid need to call strlen.
3159 * data.c (Fnumber_to_string):
3160 Use make_unibyte_string, since the string must be ASCII.
3161 * lisp.h, print.c (float_to_string): Now returns int length.
3162 * term.c (produce_glyphless_glyph):
3163 Use sprintf result rather than recomputing it.
3165 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
3166 * Makefile.in (ALL_CFLAGS):
3167 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.
3168 * gmalloc.c, regex.c: Include <config.h> unconditionally.

3172 * dispextern.h (xstrcasecmp): Define to library function
3173 strcasecmp if available.
3174 * xfaces.c: Do not use xstrcasecmp if strcasecmp is available.
3176 2012-06-25 Andreas Schwab <schwab@linux-m68k.org>

3257 Remove unnecessary forward decls.
3259 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
3261 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
3262 * lisp.h (WAIT_READING_MAX): New macro.
3263 * dispnew.c (Fsleep_for, sit_for):
3264 * keyboard.c (kbd_buffer_get_event):
3265 * process.c (Faccept_process_output):
3266 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
3267 This improves on the previous patch, which introduced a bug
3268 when time_t is unsigned and as wide as intmax_t.
3269 See <http://bugs.gnu.org/9000#51>.
3271 2012-06-23 Eli Zaretskii <eliz@gnu.org>
3273 * dispnew.c (sit_for, Fsleep_for):
3274 * keyboard.c (kbd_buffer_get_event):

3287 * sysdep.c [__FreeBSD__]: Fix more recently-introduced typos.
3288 Privately reported by Herbert J. Skuhra.
3289 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
3290 All uses changed.
3291 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
3292 not make_lisp_timeval, when the argument is of type EMACS_TIME.
3294 2012-06-23 Eli Zaretskii <eliz@gnu.org>
3296 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in
3297 last argument of make_unibyte_string.

3300 language ID in the event parameters.
3302 * w32term.c (w32_read_socket): Put the new keyboard codepage into
3303 event.code, not the obscure "character set ID".

3334 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
3336 Support higher-resolution time stamps (Bug#9000).
3337 The time stamps are only nanosecond-resolution at the C level,
3338 since that's the best that any real-world system supports now.
3339 But they are picosecond-resolution at the Lisp level, as that's
3340 easy, and leaves room for future OS improvements.
3342 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
3343 (LIBES): Use it.
3345 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
3346 Don't get current time unless it's needed.
3348 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
3349 now provides it if it's absent.
3350 (start_atimer): Port to higher-res time stamps.
3351 Check for time stamp overflow. Don't get current time more
3352 often than is needed.
3354 * buffer.h (struct buffer): Buffer modtime now has high resolution.
3355 Include systime.h, not time.h.
3356 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
3358 * dired.c: Include stat-time.h.
3359 (Ffile-attributes): File times now have higher resolution.
3361 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
3362 (struct image): Timestamp now has higher resolution.
3364 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
3365 has at least microseconds now. All uses removed.
3366 (update_frame, update_single_window, update_window, update_frame_1)
3367 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
3369 * editfns.c (time_overflow): Now extern.
3370 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
3371 (float-time, Fformat_time_string, Fcurrent_time_string)
3372 (Fcurrent_time_zone): Accept and generate higher-resolution
3373 time stamps.
3374 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
3375 (decode_time_components, lisp_seconds_argument): New functions.
3376 (make_time): Now static.
3377 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
3378 Report an error if the time is invalid, rather than having the caller
3379 do that.
3381 * fileio.c: Include <stat-time.h>
3382 (Fcopy_file): Copy higher-resolution time stamps.
3383 Prefer to set the time stamp via a file descriptor if that works.
3384 (Fset_file_times, Finsert_file_contents, Fwrite_region)
3385 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
3386 (Fvisited_file_modtime, Fset_visited_file_modtime):
3387 Support higher-resolution time stamps.
3389 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
3391 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
3393 * image.c (prepare_image_for_display, clear_image_cache)
3394 (lookup_image): Port to higer-resolution time stamps.
3396 * keyboard.c (start_polling, bind_polling_period):
3397 Check for time stamp overflow.
3398 (read_char, kbd_buffer_get_event, timer_start_idle)
3399 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
3400 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
3401 Port to higher-resolution time stamps. Do not assume time_t is signed.
3402 (decode_timer): New function. Timers are now vectors of length 9,
3403 not 8, to accommodate the picosecond component.
3404 (timer_check_2): Use it.
3406 * nsterm.m (select_timeout, timeval_subtract): Remove.
3407 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
3408 as they're a bit more accurate and handle overflow better.
3409 (ns_select): Change prototype to be compatible with pselect.
3410 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
3411 * nsterm.h (ns_select): Adjust prototype.
3413 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
3414 us-resolution time stamps.
3415 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
3417 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
3419 * lisp.h (time_overflow): New decl.
3420 (wait_reading_process_output): First arg is now intmax_t, not int,
3421 to accommodate larger waits.
3423 * process.h (struct Lisp_Process.read_output_delay):
3424 Now counts nanoseconds, not microseconds.
3425 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
3426 EMACS_HAS_USECS.
3427 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
3428 (wait_reading_process_output):
3429 Port to ns-resolution time stamps.
3430 (Faccept_process_output, wait_reading_process_output):
3431 Check for time stamp overflow. Do not assume time_t is signed.
3432 (select_wrapper): Remove; we now use pselect.
3433 (Fprocess_attributes): Now generates ns-resolution time stamps.
3435 * sysdep.c: Include utimens.h. Don't include utime.h
3436 or worry about struct utimbuf; gnulib does that for us now.
3437 (gettimeofday): Remove; gnulib provides a substitute.
3438 (make_timeval): New function.
3439 (set_file_times): Now sets ns-resolution time stamps.
3440 New arg FD; all uses changed.
3441 (time_from_jiffies, ltime_from_jiffies, get_up_time)
3442 (system_process_attributes):
3443 Now returns ns-resolution time stamp. All uses changed.
3444 Check for time stamp overflow.
3446 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
3447 provides a substitute now.
3449 * systime.h: Include timespec.h rather than sys/time.h and time.h,
3450 since it guarantees struct timespec.
3451 (EMACS_TIME): Now struct timespec, so that we can support
3452 ns-resolution time stamps.
3453 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
3454 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
3455 (EMACS_USECS): Remove.
3456 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
3457 so multiply the arg by 1000 before storing it.
3458 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
3459 New macros.
3460 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
3461 Port to ns-resolution time stamps.
3462 (EMACS_TIME_NEG_P): Remove; replaced by....
3463 (EMACS_TIME_SIGN): New macro.
3464 (EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
3465 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
3466 (set_file_times, make_time, lisp_time_argument): Adjust signature.
3467 (make_timeval, make_lisp_time, decode_time_components): New decls.
3468 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
3469 that it mishandled time_t overflow. You can't compare by subtracting!
3470 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
3471 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
3473 * term.c: Include <sys/time.h>.
3474 (timeval_to_Time): New function, for proper overflow wraparound.
3475 (term_mouse_position, term_mouse_click): Use it.
3477 * undo.c (record_first_change): Support higher-resolution time stamps
3478 in the undo buffer.
3479 (Fprimitive_undo): Use them when restoring time stamps.
3481 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
3482 (w32_get_internal_run_time):
3483 Port to higher-resolution Emacs time stamps.
3484 (ltime): Now accepts single 64-bit integer, as that's more convenient
3485 for callers.
3487 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
3489 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
3490 for compatibility with pselect. Support ns-resolution time stamps.
3492 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
3494 * xselect.c (wait_for_property_change, x_get_foreign_selection):
3495 Check for time stamp overflow, and support ns-resolution time stamps.
3497 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
3498 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
3499 (timeval_subtract): Remove; no longer needed.
3500 (XTflash, XTring_bell, x_wait_for_event):
3501 Port to ns-resolution time stamps. Don't assume time_t is signed.
3503 2012-06-22 Chong Yidong <cyd@gnu.org>

3507 2012-06-22 Eli Zaretskii <eliz@gnu.org>
3509 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
3510 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
3511 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
3512 staticidx goes up to 1597 out of 1600 = 0x640.)
3514 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
3516 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
3517 Otherwise, the umask might be mistakenly 0 while handling input signals.
3519 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
3521 * minibuf.c (Fread_string): Bind minibuffer-completion-table.

3526 * font.c, image.c, keyboard.c, lread.c, menu.c, minibuf.c, msdos.c:
3527 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
3528 access to `contents' member of Lisp_Vector objects with AREF and ASET
3529 where appropriate.
3531 2012-06-19 Chong Yidong <cyd@gnu.org>
3533 * frame.c (delete_frame): When selecting a frame on a different
3534 text terminal, do not alter the terminal's top-frame.
3536 * xdisp.c (format_mode_line_unwind_data): Record the target
3537 frame's selected window and its terminal's top-frame.
3538 (unwind_format_mode_line): Restore them.
3539 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
3540 Callers changed.
3541 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
3542 since tty frames can be explicitly named.
3543 (prepare_menu_bars): Likewise.
3545 * term.c (Ftty_top_frame): New function.
3547 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
3549 Port byte-code-meter to modern targets.
3550 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
3551 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
3552 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
3553 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
3554 (METER_1, METER_2): Simplify.
3556 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
3558 * data.c (Fdefalias): Return `symbol' (bug#11686).
3560 2012-06-18 Martin Rudalics <rudalics@gmx.at>
3562 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
3563 gets killed during executing of this function (Bug#11665).
3564 Try to always return Qt when the buffer has been actually killed.
3565 (Vkill_buffer_query_functions): In doc-string say that functions
3566 run by this hook should not change the current buffer.
3568 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
3570 Fix recently-introduced process.c problems found by static checking.
3571 * process.c (write_queue_push, write_queue_pop, send_process):
3572 Use ptrdiff_t, not int or EMACS_INT, for buffer lengths and offsets.
3573 (write_queue_pop): Fix pointer signedness problem.
3574 (send_process): Remove unused local.
3576 2012-06-17 Chong Yidong <cyd@gnu.org>
3578 * xdisp.c (redisplay_internal): No need to redisplay terminal
3579 frames that are not on top.
3581 2012-06-17 Troels Nielsen <bn.troels@gmail.com>
3583 * process.c (make_process): Initialize write_queue.
3584 (write_queue_push, write_queue_pop): New functions.
3585 (send_process): Use them to maintain correct ordering of process
3586 writes (Bug#10815).
3588 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
3590 * lisp.h (eassert): Assume C89 or later.
3591 This removes the need for CHECK.
3592 (CHECK): Remove. Its comments about always evaluating its
3593 argument were confusing, as 'eassert' typically does not evaluate
3594 its argument.
3596 * coding.c (produce_chars): Use ptrdiff_t, not int.
3598 * xterm.c (x_draw_underwave): Check for integer overflow.
3599 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.
3601 2012-06-17 Jan Djärv <jan.h.d@swipnet.se>
3603 * nsterm.m (x_free_frame_resources): Move xfree so freed memory isn't
3604 referenced (Bug#11583).

3618 (Finternal_set_lisp_face_attribute, realize_x_face):
3619 Handle wave-style underline face attributes.
3620 * xterm.c (x_draw_underwave): New function.
3621 (x_draw_glyph_string): Use it.
3623 2012-06-16 Juanma Barranquero <lekktu@gmail.com>

3690 2012-06-16 Eli Zaretskii <eliz@gnu.org>
3692 * xdisp.c (set_cursor_from_row): Don't dereference glyphs_end.
3693 If all the glyphs of the glyph row came from strings, and we have no
3694 cursor positioning clues, put the cursor on the first glyph of the
3695 row.

3697 indexing into it->string_overlays array. (Bug#11653)

3715 * .gdbinit (xgetint): Fix recently-introduced paren typo.
3716 Assume USE_2_TAGS_FOR_INTS.
3717 (xreload): Adjust $tagmask width to match recent lisp.h change.
3719 Simplify lisp.h in minor ways that should not affect code.

3721 (LISP_INT_TAG, case_Lisp_Int, LISP_STRING_TAG, LISP_INT_TAG_P)
3722 (LISP_INT1_TAG, enum Lisp_Type, XINT, XUINT, make_number):

3724 (INTTYPEBITS): New macro, for clarity.
3725 (INTMASK, MOST_POSITIVE_FIXNUM): Use it.
3726 (LISP_INT1_TAG, LISP_STRING_TAG, LISP_INT_TAG_P):

3740 2012-06-13 Andreas Schwab <schwab@linux-m68k.org>
3742 * lisp.h (Lisp_Object) [CHECK_LISP_OBJECT_TYPE]: Define as struct
3743 instead of union.
3744 (XLI, XIL): Define.
3745 (XHASH, XTYPE, XINT, XUINT, make_number, XSET, XPNTR, XUNTAG):
3746 Use them.
3747 * emacs.c (gdb_use_struct): Rename from gdb_use_union.

3772 USE_LISP_UNION_TYPE + USE_LSB_TAG cleanup (Bug#11604)
3773 * alloc.c (make_number) [!defined make_number]:

3781 USE_LSB_TAG now is always defined to be either 0 or 1.
3782 All uses changed.
3783 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
3784 code works fine either way, and efficiency is not a concern here,
3785 as the union type is for debugging, not for production.
3786 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
3787 Use an inline function on all platforms when using the union type,
3788 since this is simpler and 'static inline' can be used portably
3789 within Emacs now.
3790 (LISP_INITIALLY_ZERO): New macro.
3791 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
3792 (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.

3860 * dbusbind.c (XD_BASIC_DBUS_TYPE): Use dbus_type_is_valid and
3861 dbus_type_is_basic if available.
3862 (xd_extract_signed, xd_extract_unsigned): Rename from
3863 extract_signed and extract_unsigned, respectively. Adapt callers.
3865 2012-06-09 Chong Yidong <cyd@gnu.org>

3872 2012-06-08 Paul Eggert <eggert@cs.ucla.edu>
3874 * xdisp.c (vmessage): Treat frame message as multibyte.
3875 Without this change, (let ((§ 1)) (make-variable-buffer-local '§))
3876 would generate the diagnostic "Making \302\247 buffer-local while
3877 let-bound!".
3879 2012-06-08 Eli Zaretskii <eliz@gnu.org>
3881 * dispnew.c (showing_window_margins_p): Undo last change, which
3882 was done due to an inadvertent commit.

3894 * dispnew.c (showing_window_margins_p): Wrap in #if 0 to prevent unused
3895 function warning (the only call is inside #if 0 since 2012-06-08T08:44:45Z!eliz@gnu.org).
3897 2012-06-08 Eli Zaretskii <eliz@gnu.org>
3899 * alloc.c (allocate_vectorlike): Fix last change.
3901 2012-06-08 Dmitry Antipov <dmantipov@yandex.ru>
3903 Block-based vector allocation of small vectors.
3904 * lisp.h (struct vectorlike_header): New field `nbytes',
3905 adjust comment accordingly.
3906 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'

3921 0 items. Allocate new vector from block if vector size is less than
3922 or equal to VBLOCK_BYTES_MAX.
3923 (Fgarbage_collect): Move all vector sweeping code to sweep_vectors.
3924 (init_alloc_once): Add call to init_vectors.
3926 2012-06-08 Stefan Monnier <monnier@iro.umontreal.ca>
3928 * eval.c (Fmacroexpand): Stop if the macro returns the same form.
3930 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
3932 * doprnt.c (doprnt): Truncate multibyte char correctly.
3933 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
3934 would mishandle a string argument "Xc" if X was a multibyte
3935 character of length 2: it would truncate after X's first byte
3936 rather than including all of X.
3938 2012-06-06 Chong Yidong <cyd@gnu.org>
3940 * buffer.c (word_wrap): Doc fix.

3987 * minibuf.c (Fassoc_string): Remove duplicate declaration.
3989 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
3990 Convert pctcpu and pctmem to Lisp float properly.
3991 Let the compiler fold better, as 100.0/0x8000 is exact.
3993 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
3995 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
3996 cons_block.
3998 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>

4002 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
4004 For a 'struct window', replace some Lisp_Object fields to
4005 bitfields where appropriate, remove unused fields.
4006 * window.h (struct window): Remove unused 'last_mark_x' and
4007 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
4008 change it's type from Lisp_Object to bitfield.
4009 Change type of 'force_start', 'optional_new_start',
4010 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
4011 fields from Lisp_Object to bitfield. Adjust users accordingly.
4013 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
4015 Pacify gcc -Wdouble-precision when using Xaw.

4017 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
4018 Use 'float' consistently, rather than 'float' in most places
4019 and 'double' in a couple of places.
4021 2012-05-31 Eli Zaretskii <eliz@gnu.org>
4023 * xdisp.c (handle_stop): Detect whether we have overlay strings
4024 loaded by testing it->current.overlay_string_index to be
4025 non-negative, instead of checking whether n_overlay_strings is
4026 positive. (Bug#11587)
4028 2012-05-31 Chong Yidong <cyd@gnu.org>
4030 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
4032 * doc.c (Fsubstitute_command_keys): Doc fix.
4034 2012-05-31 Eli Zaretskii <eliz@gnu.org>
4036 * search.c (search_buffer): Remove calls to
4037 r_alloc_inhibit_buffer_relocation, as it is now called by
4038 maybe_unify_char, which was the cause of relocation of buffer text
4039 in bug#11519.
4041 2012-05-31 Eli Zaretskii <eliz@gnu.org>
4043 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
4044 for the duration of call to load_charset, to avoid problems with
4045 callers of maybe_unify_char that access buffer text through C
4046 pointers.
4048 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
4049 decrement the inhibition flag, instead of just setting or
4050 resetting it.
4052 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
4054 Remove obsolete '#define static' cruft.
4055 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
4056 This #undef was "temporary" in 2000; it is no longer needed
4057 now that '#define static' has gone away.
4058 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
4059 (gray_bitmap_bits): Remove; no longer needed.
4060 All uses replaced with definiens.

4072 (safe_bcopy): Remove decl; no longer has that name.
4073 (main): Coalesce #if into single bit of code, for simplicity.
4074 Cast pointers to uintptr_t, since standard libraries want integers
4075 and not pointers.
4076 * lisp.h (__executable_start): New decl.
4078 2012-05-31 Glenn Morris <rgm@gnu.org>
4080 * image.c (Fimagemagick_types): Doc fix.

4101 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
4103 Do not create empty overlays with the evaporate property (Bug#9642).
4104 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
4105 Bug#9642, but explicitly check that the buffer the overlay would
4106 be moved to is live and rearrange lines to make sure that errors
4107 will not put the overlay in an inconsistent state.
4108 (Fdelete_overlay): Cosmetics.
4110 2012-05-28 Eli Zaretskii <eliz@gnu.org>
4112 * w32term.c (my_bring_window_to_top): New function.
4113 (x_raise_frame): Use handle returned by DeferWindowPos, which
4114 could be different from the original one.
4115 Call my_bring_window_to_top instead of my_set_foreground_window.
4116 (Bug#11513)
4118 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
4119 by calling BringWindowToTop.

4122 (WM_EMACS_END): Increase by one.
4124 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
4126 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
4127 This avoids undefined behavior that might cause the eassert
4128 to not catch an out-of-range value.
4130 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
4132 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
4133 Update dependencies.
4135 2012-05-27 Eli Zaretskii <eliz@gnu.org>

4142 when referring to sectname field in printf format.
4144 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
4146 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
4147 Only r_alloc_inhibit_buffer_relocation needed to be added;
4148 the others were already declared.
4150 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
4151 before checking whether it's out of range. Put the check inside
4152 eassert. See
4153 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
4155 2012-05-27 Ken Brown <kbrown@cornell.edu>
4157 * callproc.c (Fcall_process): Restore a line that was accidentally
4158 commented out in the 2011-02-13 change (bug#11547).
4160 2012-05-27 Eli Zaretskii <eliz@gnu.org>
4162 * lisp.h [REL_ALLOC]: Add prototypes for external functions
4163 defined on ralloc.c.
4165 * buffer.c [REL_ALLOC]: Remove prototypes of
4166 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
4167 they are now on lisp.h.
4169 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
4171 * search.c (search_buffer): Use it to inhibit relocation of buffer
4172 text while re_search_2 is doing its job, because re_search_2 is
4173 passed C pointers to buffer text. (Bug#11519)
4175 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
4176 Update value to 24.
4178 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
4179 state after an additional call to move_it_in_display_line_to, keep
4180 the values of it->max_ascent and it->max_descent found for the
4181 entire line.
4182 (pos_visible_p): Revert the comparison against bottom_y to what it
4183 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
4184 (Bug#11464)
4186 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
4188 Fix coding-related core dumps with gcc -ftrapv.
4189 The code was computing A - B, where A and B are pointers, and B is
4190 random garbage. This can lead to core dumps on platforms that
4191 have special pointer registers, and it also leads to core dumps on
4192 x86-64 when compiled with gcc -ftrapv. The fix is to compute
4193 A - B only when B is initialized properly.
4194 * coding.c (coding_set_source, coding_set_destination): Return void.
4195 (coding_change_source, coding_change_destinations): New functions,
4196 with the old behaviors of coding_set_source and coding_set_destination.
4197 All callers that need an offset changed to use these new functions.
4199 2012-05-26 Glenn Morris <rgm@gnu.org>
4201 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
4203 2012-05-26 Eli Zaretskii <eliz@gnu.org>
4205 Extend mouse support on W32 text-mode console.
4206 * xdisp.c (draw_row_with_mouse_face):
4207 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
4209 * w32console.c: Include window.h.
4210 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
4211 New functions.
4212 (initialize_w32_display): Initialize mouse-highlight data.
4214 * w32inevt.c: Include termchar.h and window.h.
4215 (do_mouse_event): Support mouse-autoselect-window. When the mouse
4216 moves, call note_mouse_highlight. If help_echo changed, call
4217 gen_help_event to produce help-echo message in the echo area.
4218 Call clear_mouse_face if mouse_face_hidden is set in the mouse
4219 highlight info.
4221 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
4223 * lread.c (read1): Simplify slightly to avoid an overflow warning
4224 with GCC 4.7.0 on x86-64.
4226 2012-05-26 Eli Zaretskii <eliz@gnu.org>
4228 * bidi.c (bidi_mirror_char): Revert last change: an int is
4229 definitely wide enough here.
4231 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
4233 Fix integer width and related bugs (Bug#9874).
4234 * alloc.c (pure_bytes_used_lisp, pure_bytes_used_non_lisp):
4235 (allocate_vectorlike, buffer_memory_full, struct sdata, SDATA_SIZE)
4236 (string_bytes, check_sblock, allocate_string_data):

4241 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
4242 (mark_vectorlike):
4243 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4244 (allocate_pseudovector):
4245 Use int, not EMACS_INT, where int is wide enough.
4246 (inhibit_garbage_collection, Fgarbage_collect):
4247 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4248 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
4249 int might not be wide enough.
4250 (bidi_cache_search, bidi_cache_find, bidi_init_it)
4251 (bidi_count_bytes, bidi_char_at_pos, bidi_fetch_char)

4253 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
4254 (bidi_level_of_next_char, bidi_move_to_visually_next):
4255 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4256 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
4257 (Fkill_buffer, Fset_buffer_major_mode)
4258 (advance_to_char_boundary, Fbuffer_swap_text)

4261 (overlay_strings, recenter_overlay_lists)
4262 (adjust_overlays_for_insert, adjust_overlays_for_delete)
4263 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
4264 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
4265 (Foverlay_recenter, last_overlay_modification_hooks_used)
4266 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
4267 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4268 (validate_region): Omit unnecessary test for b <= e,
4269 since that's guaranteed by the previous test.
4270 (adjust_overlays_for_delete): Avoid pos + length overflow.
4271 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
4272 (report_overlay_modification):
4273 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4274 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
4275 Omit pointer cast, which isn't needed anyway, and doesn't work
4276 after the EMACS_INT -> ptrdiff_t change.
4277 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
4278 * buffer.h: Adjust decls to match defn changes elsewhere.

4283 not int, to avoid needless 32-bit limit on 64-bit hosts.
4284 (exec_byte_code): Use tighter memory-full test, one that checks
4285 for alloca overflow. Don't compute the address of the object just
4286 before an array, as that's not portable. Use EMACS_INT, not
4287 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
4288 * callint.c (Fcall_interactively):
4289 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4290 * callproc.c (call_process_kill, Fcall_process):
4291 Don't assume pid_t fits into an Emacs fixnum.
4292 (call_process_cleanup, Fcall_process, child_setup):

4294 (call_process_cleanup, Fcall_process, delete_temp_file)
4295 (Fcall_process_region):
4296 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4297 (Fcall_process): Simplify handling of volatile integers.
4298 Use int, not EMACS_INT, where int will do.
4299 * casefiddle.c (casify_object, casify_region, operate_on_word)
4300 (Fupcase_word, Fdowncase_word, Fcapitalize_word):
4301 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4302 (casify_object): Avoid integer overflow when overallocating buffer.
4303 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
4304 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
4305 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
4306 * category.h (CATEGORYP): Don't assume arg is nonnegative.
4307 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
4308 integers are now checked earlier. All uses replaced with XINT.
4309 (ccl_driver):
4310 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4311 For CCL_MapSingle, check that content and value are in int range.
4312 (ccl_driver, Fregister_code_conversion_map):
4313 Check that Vcode_version_map_vector is a vector.
4314 (resolve_symbol_ccl_program): Check that vector header is in range.
4315 Always copy the vector, so that we can check its contents reliably
4316 now rather than having to recheck each instruction as it's being
4317 executed. Check that vector words fit in 'int'.
4318 (ccl_get_compiled_code, Fregister_ccl_program)
4319 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
4320 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
4321 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
4322 contents are in range.
4323 (Fccl_execute_on_string): Check that status is in range.
4324 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
4325 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
4326 Accept and return EMACS_INT, not int, because callers can pass values
4327 out of 'int' range.
4328 (c_string_width, strwidth, lisp_string_width, chars_in_text)
4329 (multibyte_chars_in_text, parse_str_as_multibyte)

4332 (string_escape_byte8, Fget_byte):
4333 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4334 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
4335 avoid mishandling large integers.
4336 * character.h: Adjust decls to match defn changes elsewhere.
4337 * charset.c (load_charset_map_from_file, find_charsets_in_text)
4338 (Ffind_charset_region):
4339 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4340 (load_charset_map_from_file): Redo idx calculation to avoid overflow.

4342 Don't assume fixnum fits in int.
4343 (load_charset_map_from_vector, Fmap_charset_chars):
4344 Remove now-unnecessary CHECK_NATNUMs.
4345 (Fdefine_charset_internal): Check ranges here, more carefully.
4346 Don't rely on undefined behavior with signed left shift overflow.
4347 Don't assume unsigned int fits into fixnum, or that fixnum fits
4348 into unsigned int. Don't require max_code to be a valid fixnum;
4349 that's not true for gb10830 4-byte on a 32-bit host. Allow
4350 invalid_code to be a cons, for the same reason. Require code_offset
4351 to be a character. Avoid int overflow if max_char is close
4352 to INT_MAX.
4353 (CODE_POINT_TO_INDEX): On 32-bit hosts, return int, not unsigned;
4354 this is intended anyway and avoids some undefined behavior.
4355 (load_charset_map): Pass unsigned, not int, as 2nd arg of
4356 INDEX_TO_CODE_POINT, as that's what it expects.
4357 (Funify_charset, encode_char): Don't stuff unsigned vals into int vars.
4358 * charset.h (DECODE_CHAR): Return int, not unsigned;
4359 this is what was intended anyway, and it avoids undefined behavior.
4360 (CHARSET_OFFSET): Remove unused macro, instead of fixing its
4361 integer-overflow issues.
4362 (ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
4363 Formerly, it returned EMACS_INT on 64-bit hosts in the common case
4364 where the argument is EMACS_INT, and this behavior is not intended.
4365 * chartab.c (Fmake_char_table, Fset_char_table_range)
4366 (uniprop_get_decoder, uniprop_get_encoder):
4367 Don't assume fixnum fits in int.
4368 * cmds.c (move_point): New function, that does the gist of
4369 Fforward_char and Fbackward_char, but does so while checking
4370 for integer overflow more accurately.
4371 (Fforward_char, Fbackward_char): Use it.
4372 (Fforward_line, Fend_of_line, internal_self_insert)
4373 (internal_self_insert):
4374 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4375 Fix a FIXME, by checking for integer overflow when calculating
4376 target_clm and actual_clm.

4408 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
4409 (consume_chars): Rewrite to not calculate an address outside buffer.
4410 (Ffind_operation_coding_system): NATNUMP can eval its arg twice.
4411 Don't access memory outside of the args array.
4412 (Fdefine_coding_system_internal): Check for charset-id overflow.
4413 (ENCODE_ISO_CHARACTER): Use unsigned, not int, to store the unsigned
4414 result of ENCODE_CHAR.

4433 * data.c (let_shadows_buffer_binding_p, let_shadows_global_binding_p):
4434 Do not attempt to compute the address of the object just before a
4435 buffer; this is not portable.
4436 (Faref, Faset):
4437 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
4438 (Faset): Use int, not EMACS_INT, where int is wide enough.

5178 testing that it->string is a Lisp string.
5179 (get_next_display_element): When the current object is exhausted,

5192 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
5193 and right-margin display specs even if the spec is invalid or we
5194 are on a TTY, and thus unable to display on the fringes.
5195 That's because the text with the property will not be displayed anyway,
5196 so we need to signal to the caller that this is a "replacing"
5197 display spec. This fixes display when the spec is invalid or we
5198 are on a TTY.
5200 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
5202 * unexaix.c (make_hdr): Fix typo in prototype.
5203 This bug broke the build on AIX. Problem reported by Gilles Pion.
5205 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
5207 * keyboard.c (kbd_buffer_get_event): Read special events also in
5208 batch mode. (Bug#11415)
5210 2012-05-12 Glenn Morris <rgm@gnu.org>
5212 * ns.mk: Update for ns_appbindir no longer having trailing "/".
5214 2012-05-12 Eli Zaretskii <eliz@gnu.org>
5216 * lisp.mk (lisp): Add newcomment.elc.
5218 2012-05-12 Glenn Morris <rgm@gnu.org>
5220 * Makefile.in (MKDIR_P): New, set by configure.
5221 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
5223 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
5225 Remove unused function hourglass_started.
5226 * dispextern.h (hourglass_started):
5227 * w32fns.c (hourglass_started):
5228 * xdisp.c (hourglass_started): Remove.
5230 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
5232 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
5233 Update dependencies.
5235 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
5237 * xgselect.c (xg_select): Put maxfds+1 into a var.
5238 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
5240 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
5242 2012-05-10 Dave Abrahams <dave@boostpro.com>
5244 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
5245 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
5247 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
5249 * dbusbind.c (xd_registered_buses): New internal Lisp object.
5250 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
5251 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
5252 Initialize xd_registered_buses.
5254 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
5256 Untag more efficiently if USE_LSB_TAG.
5257 This is based on a proposal by YAMAMOTO Mitsuharu in
5258 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
5259 For an admittedly artificial (nth 8000 longlist) benchmark on
5260 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
5261 Emacs's overall text size by 1%.
5262 * lisp.h (XUNTAG): New macro.
5263 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
5264 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
5265 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
5266 * eval.c (Fautoload):
5267 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
5268 * frame.h (XFRAME): Use XUNTAG.
5270 Port recent dbusbind.c changes to 32-bit --with-wide-int.
5271 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
5272 Remove unportable assumptions about print widths of types like
5273 dbus_uint32_t.
5274 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
5275 intptr_t when converting between pointer and integer, to avoid GCC
5276 warnings about wrong width.
5278 2012-05-09 Eli Zaretskii <eliz@gnu.org>
5280 * w32proc.c (new_child): Force Windows to reserve only 64KB of
5281 stack for each reader_thread, instead of defaulting to 8MB
5282 determined by the linker. This avoids failures in creating
5283 subprocesses on Windows 7, see the discussion in this thread:
5284 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
5286 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
5288 Fix up display of the *Minibuf-0* buffer in the mini window.
5289 * keyboard.c (read_char): Don't clear the echo area if there's no
5290 message to clear.
5291 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
5292 contents of *Minibuf-0*) if there's no message displayed in its stead.
5294 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
5296 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
5297 batch mode.
5299 2012-05-06 Chong Yidong <cyd@gnu.org>
5301 * lisp.mk (lisp): Update.
5303 2012-05-05 Jim Meyering <meyering@redhat.com>
5305 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
5307 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
5309 * data.c (PUT_ERROR): New macro.
5310 (syms_of_data): Use it. Add new error type `user-error'.
5311 * undo.c (user_error): New function.
5312 (Fprimitive_undo): Use it.
5313 * print.c (print_error_message): Adjust print style for `user-error'.
5314 * keyboard.c (user_error): New function.
5315 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
5317 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
5319 Do not limit current-time-string to years 1000..9999.
5320 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
5321 (Fcurrent_time_string): Support any year that is supported by the
5322 underlying localtime representation. Don't use asctime, as it
5323 has undefined behavior for years outside the range -999..9999.
5325 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
5327 Fix race conditions involving setenv, gmtime, localtime, asctime.
5328 Without this fix, interrupts could mess up code that uses these
5329 nonreentrant functions, since setting TZ invalidates existing
5330 tm_zone or tzname values, and since most of these functions return
5331 pointers to static storage.
5332 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
5333 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
5334 Grow the critical sections to include not just invoking
5335 localtime/gmtime, but also accessing these functions' results
5336 including their tm_zone values if any, and any related TZ setting.
5337 (format_time_string): Last arg is now struct tm *, not struct tm **,
5338 so that the struct tm is saved in the critical section.
5339 All callers changed. Simplify allocation of initial buffer, partly
5340 motivated by the fact that memory allocation needs to be outside
5341 the critical section.
5343 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
5345 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
5346 with RESET_INTERVAL.
5348 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
5349 Remove duplicated buffer name initialization.
5351 2012-05-02 Jim Meyering <jim@meyering.net>
5353 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
5355 * xfns.c (x_window): Use xstrdup (Bug#11375).
5357 2012-05-02 Eli Zaretskii <eliz@gnu.org>
5359 * xdisp.c (pos_visible_p): If already at a newline from the
5360 display string before the 'while' loop, don't walk back the glyphs
5361 from it3.glyph_row. Solves assertion violation when the display
5362 string begins with a newline (egg.el). (Bug#11367)
5364 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
5366 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
5367 Move to simple.el.
5369 2012-05-01 Glenn Morris <rgm@gnu.org>
5371 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
5372 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
5373 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
5374 All were removed before 23.1.
5376 * dispnew.c: Remove HAVE_LIBNCURSES test;
5377 it is always true on relevant platforms.
5379 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
5380 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
5382 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
5384 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
5386 * .gdbinit (xpr): Remove checks for no longer existing misc types.
5387 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
5388 Remove.
5390 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
5392 Do not avoid creating empty evaporating overlays (Bug#9642).
5393 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
5394 That is, do not delete an evaporating overlay if it becomes
5395 empty after its bounds are adjusted to fit within its buffer.
5396 This fix caused other problems, and I'm reverting it until we get
5397 to the bottom of them.
5399 2012-04-27 Chong Yidong <cyd@gnu.org>
5401 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
5403 2012-04-27 Eli Zaretskii <eliz@gnu.org>
5405 * xdisp.c (pos_visible_p): If the window start position is beyond
5406 ZV, start the display from buffer beginning. Prevents assertion
5407 violation in init_iterator when the minibuffer window is scrolled
5408 via the scroll bar.
5410 * window.c (window_scroll_pixel_based): Likewise.
5412 2012-04-27 Chong Yidong <cyd@gnu.org>
5414 * keymap.c (where_is_internal): Doc fix (Bug#10872).
5416 2012-04-27 Glenn Morris <rgm@gnu.org>
5418 * fileio.c (Fcopy_file, Fset_file_selinux_context):
5419 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
5421 2012-04-27 Eli Zaretskii <eliz@gnu.org>
5423 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
5424 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
5426 2012-04-26 Eli Zaretskii <eliz@gnu.org>
5428 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
5429 display element, check also the underlying string or buffer
5430 character. (Bug#11341)
5432 * w32menu.c: Include w32heap.h.
5433 (add_menu_item): If the call to AppendMenuW (via
5434 unicode_append_menu) fails, disable Unicode menus only if we are
5435 running on Windows 9X/Me.
5437 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
5439 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
5440 (xgetint): Add missing shift for LSB tags.
5442 2012-04-24 Martin Rudalics <rudalics@gmx.at>
5444 * keyboard.c (read_char): Don't wipe echo area for select window
5445 events: These might get delayed via `mouse-autoselect-window'
5446 (Bug#11304).
5448 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
5450 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
5451 manipulation of :loaded-from data.
5453 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
5455 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
5456 now a cons (bug#11311).
5458 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
5460 Do not create empty overlays with the evaporate property (Bug#9642).
5461 * buffer.c (Fmove_overlay): Delete an evaporating overlay
5462 if it becomes empty after its bounds are adjusted to fit within
5463 its buffer. Without this fix, in a nonempty buffer (let ((o
5464 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))
5465 yields an empty overlay that has the evaporate property, which is
5466 not supposed to happen.
5468 Fix minor GTK3 problems found by static checking.
5469 * emacsgtkfixed.c (EMACS_TYPE_FIXED, EMACS_FIXED, EmacsFixed)
5470 (EmacsFixedPrivate, EmacsFixedClass, struct _EmacsFixed)
5471 (struct _EmacsFixedClass, emacs_fixed_get_type):
5472 Move decls here from emacsgtkfixed.h, since they needn't be public.

5474 (emacs_fixed_class_init): Omit unused local.
5475 (emacs_fixed_child_type): Remove; unused.

5478 (struct _EmacsFixedClass): Move to emacsgtkfixed.c.
5479 (EMACS_FIXED_CLASS, EMACS_IS_FIXED, EMACS_IS_FIXED_CLASS)
5480 (EMACS_FIXED_GET_CLASS): Remove; unused.
5481 * gtkutil.c (xg_create_frame_widgets) [!HAVE_GTK3]: Omit unused local.
5483 * keyboard.c (handle_async_input): Define only if SYNC_INPUT || SIGIO.
5484 Problem reported by Juanma Barranquero for Windows -Wunused-function.
5486 2012-04-22 Paul Eggert <eggert@cs.ucla.edu>
5488 Modernize and clean up gmalloc.c to assume C89 (Bug#9119).
5489 * gmalloc.c (_MALLOC_INTERNAL, _MALLOC_H, _PP, __ptr_t)
5490 (__malloc_size_t, __malloc_ptrdiff_t):
5491 Remove. All uses removed, replaced by the definiens if needed,
5492 since we can assume C89 or better now.
5493 Include <stdint.h>, for PTRDIFF_MAX, uintptr_t.
5494 (protect_malloc_state, align, get_contiguous_space)
5495 (malloc_atfork_handler_prepare, malloc_atfork_handler_parent)
5496 (malloc_atfork_handler_child, malloc_enable_thread)

5500 (special_realloc, _realloc_internal_nolock, _realloc_internal)
5501 (realloc, calloc, __default_morecore, memalign, valloc, checkhdr)
5502 (freehook, mallochook, reallochook, mabort, mcheck, mprobe):
5503 Define using prototypes, not old style.
5504 (align, _malloc_internal_nolock, _free_internal_nolock, memalign):
5505 Don't assume ptrdiff_t and uintptr_t are no wider than unsigned long.
5506 (align): Don't assume that signed integer overflow wraps around.
5507 Omit unused local var.
5508 (malloc_initialize_1, morecore_nolock, _malloc_internal_nolock)
5509 (_free_internal_nolock, memalign, mallochook, reallochook):
5510 Omit no-longer-needed casts.
5511 (valloc): Use getpagesize, not __getpagesize.
5512 (MAGICWORD, MAGICFREE): Now randomish size_t values, not 32-bit.
5513 (struct hdr): The 'magic' member is now size_t, not unsigned long.
5515 * dbusbind.c (XD_DBUS_VALIDATE_OBJECT): Define only if needed.
5517 2012-04-22 Michael Albinus <michael.albinus@gmx.de>
5519 Move functions from C to Lisp. Make non-blocking method calls
5520 the default. Implement further D-Bus standard interfaces.

5552 (Fdbus_register_signal, Fdbus_register_method): Move to dbus.el.
5553 (xd_read_message_1): Obey new structure of Vdbus_registered_objects.
5554 (xd_read_queued_messages): Obey new structure of Vdbus_registered_buses.
5555 (Vdbus_compiled_version, Vdbus_runtime_version)
5556 (Vdbus_message_type_invalid, Vdbus_message_type_method_call)

5568 * alloc.c: Handle unusual debugging option combinations.
5569 (GC_CHECK_MARKED_OBJECTS): Undef if ! GC_MARK_STACK,
5570 since the two debugging options are incompatible.
5571 (GC_MALLOC_CHECK): Similarly, undef if GC_CHECK_MARKED_OBJECTS
5572 is defined.
5573 (mem_init, mem_insert, mem_insert_fixup):
5574 Define if GC_MARK_STACK || GC_MALLOC_CHECK.
5575 (NEED_MEM_INSERT): Remove; no longer needed.
5577 2012-04-22 Leo Liu <sdl.web@gmail.com>

5583 * sysdep.c [__FreeBSD__]: Minor cleanups.
5584 (list_system_processes, system_process_attributes) [__FreeBSD__]:
5585 Use Emacs indenting style more consistently. Avoid some casts.
5586 Use 'double' consistently rather than mixing 'float' and 'double'.
5588 2012-04-21 Eduard Wiebe <usenet@pusto.de>
5590 * sysdep.c (list_system_processes, system_process_attributes):
5591 Add implementation for FreeBSD (Bug#5243).

5625 row, return zero immediately.
5626 (try_cursor_movement): If inside continuation line, don't back up
5627 farther than the first row after the header line, if any.
5628 Don't consider the header-line row as "partially visible", even if
5629 MATRIX_ROW_PARTIALLY_VISIBLE_P returns non-zero. (Bug#11261)
5631 2012-04-20 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
5633 * lread.c (lisp_file_lexically_bound_p): Fix hang at ";-*-\n"

5645 -Wunused-but-set-variable, -Wunused-function, -Wunused-macros,
5646 -Wunused-result, -Wunused-variable. This should go away once
5647 the Emacs and Gnulib regex code is merged.

5661 (syms_of_dired): Add them.
5663 2012-04-16 Paul Eggert <eggert@cs.ucla.edu>
5665 Fix minor alloc.c problems found by static checking.
5666 * alloc.c (_malloc_internal, _free_internal) [!DOUG_LEA_MALLOC]:
5667 New extern decls, to avoid calling undeclared functions.
5668 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
5669 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
5670 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.
5671 (NEED_MEM_INSERT): New macro.
5672 (mem_insert, mem_insert_fixup) [!NEED_MEM_INSERT]: Remove; unused.
5673 Remove one incorrect comment and fix another.

5678 (r_alloc_size_in_use, r_alloc_freeze, r_alloc_thaw): Remove; unused.
5679 (r_alloc_sbrk): Now static.
5681 Improve ralloc.c interface checking.
5682 See http://lists.gnu.org/archive/html/emacs-devel/2011-12/msg00720.html
5683 * buffer.c (ralloc_reset_variable, r_alloc, r_re_alloc)
5684 (r_alloc_free) [REL_ALLOC]: Move decls from here ...

5686 [REL_ALLOC]: ... to here, to check interface.
5687 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
5688 Remove decls. This fixes an "It stinks!".
5690 * alloc.c (which_symbols): Fix alignment issue / type clash.
5692 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
5694 * lisp.h (struct Lisp_Symbol): Remove explicit padding.
5695 (struct Lisp_Misc_Any): Likewise.
5696 (struct Lisp_Free): Likewise.

5705 2012-04-14 Paul Eggert <eggert@cs.ucla.edu>
5707 Make GC_MAKE_GCPROS_NOOPS the default (Bug#9926).
5708 * lisp.h (GC_MARK_STACK): Default to GC_MAKE_GCPROS_NOOPS.
5709 * s/cygwin.h, s/darwin.h, s/freebsd.h, s/gnu.h, s/irix6-5.h, s/msdos.h:
5710 * s/netbsd.h, s/sol2-6.h:
5711 Remove definition of GC_MARK_STACK, since the default now works.
5712 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
5713 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
5714 no longer the default.
5715 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
5717 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)
5719 * lread.c (lisp_file_lexically_bound_p):
5720 Fix hang at ";-*-\n" (bug#11238).
5722 2012-04-14 Eli Zaretskii <eliz@gnu.org>
5724 * xdisp.c (find_last_unchanged_at_beg_row): Don't consider a row

5727 2012-04-14 Jan Djärv <jan.h.d@swipnet.se>
5729 * nsterm.m (constrainFrameRect): Always constrain when there is only
5730 one screen (Bug#10962).
5732 2012-04-13 Ken Brown <kbrown@cornell.edu>
5734 * s/cygwin.h (PTY_OPEN): Don't try to close a bogus file descriptor.
5736 2012-04-13 Reuben Thomas <rrt@sc3d.org>
5738 * indent.c (Fmove_to_column): Change interactive spec (Bug#739).
5740 2012-04-11 Daniel Colascione <dancol@dancol.org>
5742 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
5743 against is gone. It's better to use vfork now so that when Cygwin
5744 gains a new, working vfork, we use it automatically (bug#10398).
5746 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>
5748 * window.c (save_window_save): Obey window-point-insertion-type.
5750 2012-04-11 Glenn Morris <rgm@gnu.org>
5752 * Makefile.in (GNUSTEP_CFLAGS): Rename from C_SWITCH_X_SYSTEM.

5758 2012-04-10 Jason S. Cornez <jcornez@ravenpack.com> (tiny change)
5760 * keyboard.c: Override inhibit-quit after the third C-g (bug#6585).
5761 (force_quit_count): New var.
5762 (handle_interrupt): Use it.
5764 2012-04-10 Juanma Barranquero <lekktu@gmail.com>
5766 * w32.c (w32_delayed_load): Record the full path of the library
5767 being loaded (bug#10424).
5769 2012-04-09 Glenn Morris <rgm@gnu.org>
5771 * doc.c (Fsnarf_documentation): Check variables, functions are bound,
5772 not just in the obarray, before snarfing them. (Bug#11036)
5774 * Makefile.in ($(leimdir)/leim-list.el):
5775 Pass EMACS rather than BUILT_EMACS.
5777 2012-04-09 Teodor Zlatanov <tzz@lifelogs.com>
5779 * process.c (make_process):
5780 * process.h: Add integer `gnutls_handshakes_tried' member to
5781 process struct.
5783 * gnutls.h: Add `GNUTLS_EMACS_HANDSHAKES_LIMIT' upper limit.
5784 Add convenience `GNUTLS_LOG2i' macro.
5786 * gnutls.c (gnutls_log_function2i): Convenience log function.
5787 (emacs_gnutls_read): Use new log functions,
5788 `gnutls_handshakes_tried' process member, and
5789 `GNUTLS_EMACS_HANDSHAKES_LIMIT' to limit the number of handshake
5790 attempts per process (connection).
5792 2012-04-09 Chong Yidong <cyd@gnu.org>
5794 * eval.c (Fuser_variable_p, user_variable_p_eh)
5795 (lisp_indirect_variable): Functions deleted.
5796 (Fdefvar): Caller changed.
5798 * callint.c (Finteractive, Fcall_interactively):
5799 * minibuf.c (Fread_variable): Callers changed.
5801 2012-04-09 Eli Zaretskii <eliz@gnu.org>
5803 * xdisp.c (set_cursor_from_row): If the display string appears in
5804 the buffer at position that is closer to point than the position
5805 after the display string, display the cursor on the first glyph of
5806 the display string. Fixes cursor display when a 'display' text
5807 property immediately follows invisible text. (Bug#11094)
5809 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
5811 composite.c: use 'double' consistently
5812 * composite.c (get_composition_id): Use 'double' consistently
5813 instead of converting 'float' to 'double' and vice versa; this is
5814 easier to understand and avoids a GCC warning.
5816 2012-04-09 Glenn Morris <rgm@gnu.org>
5818 * Makefile.in: Generate leim-list with bootstrap-emacs, in
5819 preparation for dumping it with emacs. (Bug#4789)
5820 (leimdir): New variable.
5821 ($(leimdir)/leim-list.el): New rule.
5822 (emacs$(EXEEXT)): Depend on leim-list.el.

5826 (init_buffer_once, syms_of_buffer): Remove Qucs_set_table_for_input.
5828 2012-04-08 Andreas Schwab <schwab@linux-m68k.org>
5830 * lisp.h (struct Lisp_Symbol): Add explicit padding to ensure
5831 proper alignment.

5835 * xml.c (init_libxml2_functions) [WINDOWSNT]:
5836 Remove unused local variable.
5838 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
5840 Avoid unnecessary pointer scanning in garbage collection (Bug#10780).
5841 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
5842 (mark_memory): Mark Lisp_Objects only if pointers might hide in
5843 objects, as mark_maybe_pointer will catch them otherwise.
5844 (GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
5845 * s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.
5847 2012-04-07 Paul Eggert <eggert@cs.ucla.edu>
5849 Fix typo that broke non-Windows builds.
5850 * xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.
5852 2012-04-07 Eli Zaretskii <eliz@gnu.org>
5854 Support building on MS-Windows with libxml2.
5856 * makefile.w32-in (OBJ2): Add xml.$(O).
5857 (GLOBAL_SOURCES): Add xml.c.
5858 ($(BLD)/xml.$(O)): New dependency list.
5860 * xml.c (DEF_XML2_FN, LOAD_XML2_FN) [WINDOWSNT]: New macros.
5861 (fn_htmlReadMemory, fn_xmlReadMemory, fn_xmlDocGetRootElement)
5862 (fn_xmlFreeDoc, fn_xmlCleanupParser, fn_xmlCheckVersion)
5863 [!WINDOWSNT]: New macros.
5864 (init_libxml2_functions, libxml2_loaded_p): New functions.
5865 (parse_region): Call fn_xmlCheckVersion instead of using the macro
5866 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
5867 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
5868 Calls xmlCleanupParser only if libxml2 was loaded (or statically
5869 linked in).
5870 (Flibxml_parse_html_region, Flibxml_parse_xml_region):
5871 Call init_libxml2_functions before calling libxml2 functions.
5872 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
5874 * emacs.c: Don't include libxml/parser.h.
5875 (shut_down_emacs): Call xml_cleanup_parser, instead of calling
5876 xmlCleanupParser directly.
5878 * lisp.h [HAVE_LIBXML2]: Add prototype for xml_cleanup_parser.
5880 2012-04-07 Eli Zaretskii <eliz@gnu.org>
5882 * indent.c (Fvertical_motion): If there is a display string at
5883 point, use it.vpos to compute how many lines to backtrack after
5884 move_it_to point. (Bug#11133)
5886 2012-04-06 Eli Zaretskii <eliz@gnu.org>
5888 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
5889 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
5890 about subtle differences between FETCH_CHAR* and STRING_CHAR*
5891 macros related to unification of CJK characters. For the details,
5892 see the discussion following the message here:
5893 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
5895 2012-04-04 Chong Yidong <cyd@gnu.org>
5897 * keyboard.c (Vdelayed_warnings_list): Doc fix.
5899 2012-04-01 Eli Zaretskii <eliz@gnu.org>
5901 * w32menu.c (simple_dialog_show, add_menu_item): Use SAFE_ALLOCA
5902 instead of alloca. (Bug#11138)
5904 2012-04-01 Andreas Schwab <schwab@linux-m68k.org>
5906 * w32menu.c (is_simple_dialog): Properly check lisp types.
5907 (Bug#11141)
5909 2012-03-31 Eli Zaretskii <eliz@gnu.org>
5911 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
5912 position we get to after a call to move_it_to fails the
5913 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
5914 only if we wind up in a string from display property. (Bug#11063)
5916 * window.c (Fdelete_other_windows_internal): Invalidate the row
5917 and column information about mouse highlight, so that redisplay
5918 restores it after reallocating the glyph matrices. (Bug#7464)
5920 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
5921 string comes from a `display' text property, use the buffer
5922 position of that property as if we actually saw that position in
5923 the row's glyphs.
5924 (move_it_by_lines): Remove the assertion that
5925 "it->current_x == 0 && it->hpos == 0" which can be legitimately
5926 violated when there's a before-string at the beginning of a line.
5927 (Bug#11063)
5929 2012-03-30 Eli Zaretskii <eliz@gnu.org>
5931 * xdisp.c (append_space_for_newline): If the default face was
5932 remapped, use the remapped face for the appended newline.
5933 (extend_face_to_end_of_line): Use the remapped default face for
5934 extending the face to the end of the line.
5935 (display_line): Call extend_face_to_end_of_line when the default
5936 face was remapped. (Bug#11068)
5938 2012-03-29 Eli Zaretskii <eliz@gnu.org>
5940 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
5942 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
5944 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
5946 2012-03-27 Glenn Morris <rgm@gnu.org>
5948 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
5949 Doc fixes.
5951 2012-03-26 Kenichi Handa <handa@m17n.org>
5953 * dispextern.h (struct glyph): Fix previous change. Change the
5954 bit length of glyphless.ch to 25 (Bug#11082).
5956 2012-03-26 Chong Yidong <cyd@gnu.org>
5958 * keyboard.c (Vselection_inhibit_update_commands): New variable.
5959 (command_loop_1): Use it; inhibit selection update for
5960 handle-select-window too (Bug#8996).
5962 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
5964 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
5966 2012-03-25 Kenichi Handa <handa@m17n.org>
5968 * dispextern.h (struct glyph): Change the bit length of
5969 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
5971 2012-03-24 Eli Zaretskii <eliz@gnu.org>
5973 * s/ms-w32.h (tzname): Include time.h before redirecting to
5974 _tzname. Fixes the MSVC build. (Bug#9960)
5976 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
5978 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
5979 characters.
5981 * xterm.c (XTread_socket): Only modify handling_signal if
5982 !SYNC_INPUT. (Bug#11080)
5984 2012-03-23 Eli Zaretskii <eliz@gnu.org>
5986 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
5987 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
5988 when fetching a multibyte character consumes more bytes than
5989 CHAR_BYTES returns, due to unification of CJK characters in
5990 string_char. (Bug#11073)
5992 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
5994 * process.c (wait_reading_process_output): Handle pty disconnect
5995 by refraining from sending oneself a SIGCHLD (bug#10933).

5999 * dispextern.h (struct it): New member string_from_prefix_prop_p.
6001 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
6002 Mark string as coming from a prefix property.
6003 (handle_face_prop): Use default face for prefix strings (Bug#4281).
6004 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
6006 2012-03-21 Chong Yidong <cyd@gnu.org>
6008 * xfaces.c (Vface_remapping_alist): Doc fix.
6010 2012-03-20 Eli Zaretskii <eliz@gnu.org>
6012 * w32proc.c (Fw32_set_console_codepage)
6013 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
6014 Doc fixes.
6016 2012-03-20 Chong Yidong <cyd@gnu.org>
6018 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
6019 to reflect default non-nil value of redisplay-dont-pause.

6024 it fit in a valid range (Bug#11003).
6026 2012-03-18 Eli Zaretskii <eliz@gnu.org>
6028 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
6029 that is not from display property, accept the row as a "cursor
6030 row" if one of the string's character has a non-nil `cursor'
6031 property. Fixes cursor positioning when there are newlines in
6032 overlay strings, e.g. in icomplete.el. (Bug#11035)
6034 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
6036 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
6038 2012-03-12 Chong Yidong <cyd@gnu.org>
6040 * eval.c (inhibit_lisp_code): Rename from
6041 inhibit_window_configuration_change_hook; move from window.c.
6043 * xfns.c (unwind_create_frame_1, Fx_create_frame):
6044 * window.c (run_window_configuration_change_hook)
6045 (syms_of_window): Callers changed.
6047 2012-03-11 Chong Yidong <cyd@gnu.org>
6049 * keymap.c (Fkey_description): Doc fix (Bug#9700).
6051 * editfns.c (Fconstrain_to_field): Doc fix (Bug#9452).
6053 2012-03-10 Chong Yidong <cyd@gnu.org>
6055 * frame.c (other_visible_frames): Don't assume the selected frame
6056 is visible (Bug#10955).
6058 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
6060 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
6062 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
6064 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
6065 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
6066 zero (Bug#10954).
6068 2012-03-03 Glenn Morris <rgm@gnu.org>
6070 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
6072 2012-03-02 Eli Zaretskii <eliz@gnu.org>
6074 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
6075 position past the first glyph_row that ends at ZV. (Bug#10902)
6076 (redisplay_window, next_element_from_string): Fix typos in
6077 comments.
6078 (redisplay_window): Pass to move_it_vertically the margin in
6079 pixels, not in screen lines.
6081 2012-03-02 Glenn Morris <rgm@gnu.org>
6083 * buffer.c (buffer-list-update-hook): Doc fix.
6085 2012-02-29 Eli Zaretskii <eliz@gnu.org>
6087 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
6088 push_it before setting up the iterator for the first overlay
6089 string, even if we have an empty string loaded.
6090 (next_overlay_string): If there's an empty string on the iterator
6091 stack, pop the stack. (Bug#10903)
6093 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
6095 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
6096 Suggested by Stefan Monnier in
6097 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
6098 * alloc.c (widen_to_Lisp_Object): New static function.
6099 (mark_memory): Also mark Lisp_Objects by fetching pointer words
6100 and widening them to Lisp_Objects. This would work even if
6101 USE_LSB_TAG is defined and wide integers are used, which might
6102 happen in a future version of Emacs.
6104 2012-02-25 Chong Yidong <cyd@gnu.org>
6106 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
6107 Doc fix.
6109 * xselect.c (Fx_selection_exists_p): Doc fix.
6110 (x_clipboard_manager_save_all): Print an informative message
6111 before saving to clipboard manager.
6113 2012-02-24 Chong Yidong <cyd@gnu.org>

6143 when computing $valmask.
6145 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
6146 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
6147 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
6148 It's useless in that case, and it can cause problems on hosts
6149 that allocate halves of EMACS_INT values separately.
6150 Reported by Dan Horák. Diagnosed by Andreas Schwab in
6151 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
6152 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
6153 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
6154 it avoids undefined behavior on hosts where shifting right by more
6155 than the word width has undefined behavior.
6157 2012-02-19 Chong Yidong <cyd@gnu.org>
6159 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
6160 (Funhandled_file_name_directory, Ffile_name_as_directory)

6197 2012-02-12 Chong Yidong <cyd@gnu.org>
6199 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
6200 as that creates a dangerous corner case.
6202 * window.c (Fdelete_window_internal): Invalidate the mouse
6203 highlight (Bug#9904).
6205 2012-02-12 Glenn Morris <rgm@gnu.org>

6237 * buffer.c (Fbuffer_local_variables)
6238 (buffer_lisp_local_variables): Handle unbound vars correctly;
6239 don't let Qunbound leak into Lisp.
6241 2012-02-07 Glenn Morris <rgm@gnu.org>
6243 * image.c (Fimagemagick_types): Doc fix.
6245 * image.c (imagemagick-render-type): Change it from a lisp object

6281 * character.c (char_width): Return EMACS_INT, not int.
6282 (char_width, c_string_width): Check for overflow when
6283 computing the width; this is possible now that individual
6284 characters can have unbounded width. Problem introduced

6820 (ALIGN_GCTYPEBITS) [_MSC_VER]: Define.
6821 (DECL_ALIGN) [_MSC_VER]: Use it, as MSVC doesn't like bit ops in

6939 is set, removing the need for VIRT_ADDRESS_VARIES.
6940 (PURE_P): Use a more-efficient implementation that needs just one

6947 consistency with the new puresize.h.
6948 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.

6956 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
6957 behave as if the cursor position were at the window margin.
6959 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
6960 and the cursor position is out of bounds, behave as if the cursor
6961 position were at the window margin. (Bug#10075)
6963 2011-11-18 Chong Yidong <cyd@gnu.org>
6965 * window.c (Fwindow_combination_limit): Make first argument

6987 compute_line_metrics.
6988 (compute_line_metrics): Call row_hash, instead of computing the
6989 hash code inline.
6991 * dispnew.c (verify_row_hash): Call row_hash for computing the
6992 hash code of a row, instead of duplicating code from xdisp.c.
6994 * dispextern.h (row_hash): Add prototype.
6996 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>
6998 * frame.c (delete_frame): Don't delete the terminal when the last

7047 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
7048 with user-defined heap size. Bump the default size of the temacs
7049 heap to 27MB, to avoid memory warning when running temacs.

7171 * xmenu.c (cleanup_widget_value_tree): New function.
7172 (xmenu_show, xdialog_show): Use it in record_unwind_protect instead of

7179 (window_box_width, window_box_left, window_box_left_offset)
7180 (window_box_right, window_box_right_offset): Declare extern.
7181 Otherwise, these inline functions do not conform to C99 and
7182 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
7183 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
7184 * intervals.c (adjust_intervals_for_insertion)

7187 (static_offset_intervals): Remove.
7188 (offset_intervals): Rewrite using the old contents of
7189 static_offset_intervals. The old version didn't conform to C99

7327 Rename cover_string to disp_string.
7329 2011-11-01 Martin Rudalics <rudalics@gmx.at>

7503 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
7504 * editfns.c: Rewrite current-time-zone so that it invokes
7505 the equivalent of (format-time-string "%Z") to get the time zone name.
7506 This fixes a bug when the time zone name contains characters that
7507 need converting from the system time locale to Emacs internal format.
7508 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
7509 that patch fixed format-time-string to do the conversion, but
7510 I forgot to fix current-time-zone.
7511 (format_time_string): New function, containing most of
7512 what Fformat_time_string used to contain.
7513 (Fformat_time_string): Rewrite in terms of format_time_string.

7517 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
7518 Jason Rumney's 2007-06-07 change worked around this bug, but
7519 didn't fix it.
7520 * systime.h (tzname, timezone): Remove no-longer-used declarations.
7522 2011-10-19 Eli Zaretskii <eliz@gnu.org>
7524 * xdisp.c (start_display): If the character at POS is displayed
7525 via a display vector, reset IT->current.dpvec_index to zero.
7526 (try_window_reusing_current_matrix): If a line ends in a display
7527 vector or the next line starts in a display vector, continue
7528 redrawing the window even though the character position of
7529 start_row was reached.
7530 (Bug#9771, part 2)

7534 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
7535 with nobreak-char-display too.
7537 2011-10-18 Eli Zaretskii <eliz@gnu.org>
7539 Fix part 3 of bug#9771.
7540 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
7541 (bidi_resolve_neutral): Don't enter the expensive loop looking for
7542 non-neutral characters if the current character is a paragraph
7543 separator (a.k.a. Newline). This avoids running the same
7544 expensive loop twice, once when we consume the preceding newline
7545 and the other time when the line actually needs to be displayed.
7546 Avoid the loop when we see neutrals on the base embedding level
7547 following a character whose directionality is the same as the
7548 paragraph's. This avoids running the expensive loop when a line
7549 ends in a long sequence of neutrals, like control characters.
7550 Add assertion against STRONG_AL type. Slightly rearrange code
7551 that determines the type of a neutral given the first non-neutral
7552 that follows it.
7553 (bidi_level_of_next_char): Set next_en_pos to zero when
7554 invalidating its info.
7556 2011-10-17 Eli Zaretskii <eliz@gnu.org>
7558 * xdisp.c (push_display_prop): Determine whether to record string
7559 or buffer position by IT->string, not by IT->method. Allow
7560 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
7561 (move_it_vertically_backward): Don't look for character position
7562 immediately after the newline when in a continuation line.
7563 (Bug#9771, part 1)
7565 2011-10-15 Martin Rudalics <rudalics@gmx.at>
7567 * window.c (coordinates_in_window): Rewrite and delabelize
7568 vertical border check. (Bug#5357) (Bug#9618)
7570 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
7572 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
7573 errors in XSetWindowBorder (bug#9310).
7575 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
7577 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
7578 avoid crash when xmalloc overrun checking is enabled.
7580 2011-10-13 Eli Zaretskii <eliz@gnu.org>
7582 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
7583 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
7584 cursor motion with <left> and <right> arrow keys.
7586 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
7587 some callers set that themselves.
7589 2011-10-12 Eli Zaretskii <eliz@gnu.org>
7591 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
7592 display string and the previous row comes from the same string and
7593 is empty. (Bug#9739) (Bug#9738)
7595 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
7597 * doc.c (get_doc_string): Encode file name (bug#9735).
7599 2011-10-12 Eli Zaretskii <eliz@gnu.org>
7601 * bidi.c (bidi_level_of_next_char):
7602 * xdisp.c (get_visually_first_element): Remove old incorrect
7603 comments regarding the Unicode Line Separator character.
7605 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
7607 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
7609 * alloc.c (Fgc_status): Do not access beyond zombies array
7610 boundary if nzombies > MAX_ZOMBIES.
7611 * alloc.c (dump_zombies): Add missing format specifier.
7613 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
7615 * xdisp.c (set_cursor_from_row): Simplify conditionals,
7616 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
7618 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
7619 Some packages use them to denote characters with modifiers.
7621 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
7623 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
7624 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
7625 matching a pp-number. Rename parameter var to var1.
7627 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
7629 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
7631 2011-10-08 Glenn Morris <rgm@gnu.org>
7633 * callint.c (Fcall_interactively): Give a more explicit error for the
7634 'c' case with a non-character input. (Bug#8479)
7636 2011-10-08 Eli Zaretskii <eliz@gnu.org>
7638 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
7639 lines.
7640 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
7641 lines that are hscrolled on the left.
7643 * dispnew.c (buffer_posn_from_coords): Account for a possible
7644 presence of header-line. (Bug#4426)
7646 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
7648 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
7649 Don't advertise functionality which we discourage or doesn't work.
7651 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
7653 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
7654 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
7655 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
7656 this makes Emacs dump core during garbage collection on rare
7657 occasions. sizeof is obviously inferior to offsetof here, so
7658 stick with offsetof.
7659 (GC_POINTER_ALIGNMENT): New macro.
7660 (mark_memory): Omit 3rd (offset) arg; caller changed.
7661 Don't assume EMACS_INT alignment is the same as pointer alignment.
7663 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
7665 * keyboard.c (read_key_sequence_remapped): New var.
7666 (read_key_sequence): Compute remapping in the right buffer.
7667 (command_loop_1): Use read_key_sequence's remapping directly.
7669 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
7671 * dired.c (file_name_completion): Don't expand file name.
7672 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
7673 before checking file name handler.
7675 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
7676 they've been requested explicitly (bug#9591).
7678 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
7680 * keymap.c (Fsingle_key_description): Use make_specified_string
7681 instead of build_string to build string from push_key_description.
7682 (Bug#5193)
7684 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
7686 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
7687 This fixes a Y2038 bug on 64-bit hosts.
7688 * buffer.c (reset_buffer):
7689 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
7690 (Fclear_buffer_auto_save_failure):
7691 Use 0, not -1, to represent an unset failure time, since time_t
7692 might not be signed.
7694 Remove dependency on glibc malloc internals.
7695 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7696 Move back here from lisp.h, but with their new implementations.
7697 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7698 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
7699 * charset.c (charset_table_init): New static var.
7700 (syms_of_charset): Use it instead of xmalloc. This removes a
7701 dependency on glibc malloc internals. See Eli Zaretskii's comment in
7702 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
7703 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7704 Move back to alloc.c.
7705 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7706 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
7708 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
7710 * nsterm.m (windowDidResize): Call x_set_window_size only when
7711 ns_in_resize is true. Otherwise set pixelwidth/height and
7712 call change_frame_size (Bug#9628).
7714 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
7716 Port --enable-checking=all to Fedora 14 x86-64.
7717 * charset.c (syms_of_charset): Also account for glibc malloc's
7718 internal overhead when calculating the initial malloc maximum.
7720 Port --enable-checking=all to Fedora 14 x86.
7721 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7722 Move to lisp.h.
7723 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
7724 (overrun_check_realloc, overrun_check_free):
7725 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
7726 That way, xmalloc returns a properly-aligned pointer even if
7727 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
7728 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
7729 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
7730 into account when calculating the initial malloc maximum.
7731 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
7732 Move here from alloc.c, so that charset.c can use it too.
7733 Properly align; the old code wasn't right for common 32-bit hosts
7734 when configured with --enable-checking=all.
7735 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
7736 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
7738 2011-09-29 Eli Zaretskii <eliz@gnu.org>
7740 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
7741 use EDOM.
7743 2011-09-28 Eli Zaretskii <eliz@gnu.org>
7745 * xdisp.c (compute_display_string_end): If there's no display
7746 string at CHARPOS, return -1.
7748 * bidi.c (bidi_fetch_char): When compute_display_string_end
7749 returns a negative value, treat the character as a normal
7750 character not covered by a display string. (Bug#9624)
7752 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
7754 * lread.c (Fread_from_string): Fix typo in docstring.
7756 2011-09-27 Eli Zaretskii <eliz@gnu.org>
7758 * xdisp.c (handle_invisible_prop): If invisible text ends on a
7759 newline, reseat the iterator instead of bidi-iterating there one
7760 character at a time. (Bug#9610)
7761 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
7762 TO_CHARPOS if the bidi iterator is at base embedding level.
7764 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
7766 * lread.c (readevalloop): Use correct code for NBSP.
7767 (read1): Likewise. (Bug#9608)
7769 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
7771 * dbusbind.c (Fdbus_register_signal): When service is not
7772 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
7774 2011-09-25 Glenn Morris <rgm@gnu.org>
7776 * buffer.c (truncate-lines): Doc fix.
7778 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
7780 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
7781 (Fset_window_next_buffers): Doc fix.
7783 2011-09-24 Glenn Morris <rgm@gnu.org>
7785 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
7787 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
7789 Fix minor problems found by static checking.
7790 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
7791 * indent.c (Fvertical_motion): Fix == vs = typo.
7793 2011-09-24 Eli Zaretskii <eliz@gnu.org>
7795 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
7796 Default value is now t. Doc fix.
7798 * indent.c (Fvertical_motion): Compute and apply the overshoot
7799 logic when moving up, not only when moving down. Fix the
7800 confusing name and values of the it_overshoot_expected variable;
7801 logic changes accordingly. (Bug#9254) (Bug#9549)
7803 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
7804 CHARPOS is covered by a display string which includes newlines.
7805 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
7806 is covered by a display string with embedded newlines.
7808 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
7810 * dbusbind.c (Fdbus_register_signal): Add match rule to
7811 Vdbus_registered_objects_table. (Bug#9581)
7812 (Fdbus_register_method, Vdbus_registered_objects_table):
7813 Fix docstring.
7815 2011-09-24 Jim Meyering <meyering@redhat.com>
7817 do not ignore write error for any output size
7818 The previous change was incomplete.
7819 While it makes emacs --batch detect the vast majority of stdout
7820 write failures, errors were still ignored whenever the output size is
7821 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
7822 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
7823 && echo FAIL: ignored write error
7824 FAIL: ignored write error
7825 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
7826 && echo FAIL: ignored write error
7827 FAIL: ignored write error
7828 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
7830 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
7832 * emacs.c (Fkill_emacs): In noninteractive mode exit
7833 non-successfully if a write error occurred on stdout. (Bug#9574)
7835 2011-09-21 Eli Zaretskii <eliz@gnu.org>
7837 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
7838 the xassert test.
7840 * dispextern.h (struct it): Update the comment documenting what
7841 can it->OBJECT be.
7843 2011-09-20 Eli Zaretskii <eliz@gnu.org>
7845 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
7846 a display string, extend search for cursor position to end of row.
7847 (find_row_edges): If the row ends in a newline from a display
7848 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
7849 Handle the case of a display string with multiple newlines.
7850 (Fcurrent_bidi_paragraph_direction): Fix search for previous
7851 non-empty line. Fixes confusing cursor motion with arrow keys at
7852 the beginning of a line that starts with whitespace.
7854 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
7856 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
7857 (bug#9493).
7859 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
7861 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
7862 boolean (Bug#9154).
7864 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7866 * xdisp.c (display_line): Record maximum and minimum buffer
7867 positions even if no glyphs were produced (e.g., by a zero-width
7868 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
7869 buffer positions that will be removed from the glyph row because
7870 they don't fit.
7871 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
7872 column is beyond frame width: don't subtract 1 "pixel" when
7873 computing width of the stretch.
7874 (reseat_at_next_visible_line_start): Undo the change made on
7875 2011-09-17 that saved paragraph information and restored it after
7876 the call to `reseat'. (Bug#9545)
7878 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
7880 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
7881 and turn window cursor on if cleared (Bug#9415).
7883 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
7885 * search.c (boyer_moore): Take unibyte characters from pattern
7886 literally. (Bug#9458)
7888 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7890 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
7892 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
7894 Fix minor problem found by static checking.
7895 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
7896 initialized, to pacify gcc -Wuninitialized.
7898 * fileio.c: Report proper errno when syscall falls.
7899 (Finsert_file_contents): Save and restore errno,
7900 so that report_file_error outputs the correct diagnostic.
7901 (Fwrite_region) [CLASH_DETECTION]: Likewise.
7903 2011-09-18 Eli Zaretskii <eliz@gnu.org>
7905 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
7907 2011-09-17 Eli Zaretskii <eliz@gnu.org>
7909 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
7910 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9530)
7912 2011-09-17 Eli Zaretskii <eliz@gnu.org>
7914 * xdisp.c (reseat_at_next_visible_line_start): Keep information
7915 about the current paragraph and restore it after the call to reseat.
7917 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
7918 (bidi_find_paragraph_start): Search back for paragraph beginning
7919 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
7920 (bidi_move_to_visually_next): Only trigger paragraph-related
7921 computations when the last character is a newline or at EOB, not
7922 just any NEUTRAL_B. (Bug#9470)
7924 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
7925 truncated lines if point is covered by a display string. (Bug#9524)
7927 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
7929 * xselect.c: Relax test for outgoing X longs (Bug#9498).
7930 (cons_to_x_long): New function.
7931 (lisp_data_to_selection_data): Use it. Correct the test for
7932 short-versus-long data; it was negated. Break out of vector
7933 loop, for efficiency, when a long datum is discovered.
7935 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
7937 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
7939 2011-09-16 Eli Zaretskii <eliz@gnu.org>
7941 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
7942 GCC PR/17406) by declaring this function with external scope.
7944 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
7946 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
7947 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
7949 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
7951 * editfns.c (Fformat): Correctly handle text properties on "%%".
7953 2011-09-15 Eli Zaretskii <eliz@gnu.org>
7955 * xterm.c (x_draw_composite_glyph_string_foreground):
7956 * w32term.c (x_draw_composite_glyph_string_foreground):
7957 * term.c (encode_terminal_code):
7958 * composite.c (composition_update_it, get_composition_id):
7959 * xdisp.c (get_next_display_element)
7960 (fill_composite_glyph_string): Add comments about special meaning
7961 of TAB characters in a composition.
7963 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
7965 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
7966 This occurs when processing a multibyte format.
7967 Problem reported by Wolfgang Jenker.
7969 2011-09-15 Johan Bockgård <bojohan@gnu.org>
7971 * xdisp.c (try_cursor_movement): Only check for exact match if
7972 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
7974 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7976 Remove unused external symbols.
7977 * dispextern.h (calc_pixel_width_or_height): Remove decl.
7978 * xdisp.c (calc_pixel_width_or_height): Now static.
7979 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
7980 * indent.c (check_display_width):
7981 * w32term.c: Fix comment to match code.
7982 * xterm.c, xterm.h (x_catching_errors): Remove.
7984 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
7986 * xselect.c: Use signed conversions more consistently (Bug#9498).
7987 (selection_data_to_lisp_data): Assume incoming selection data are
7988 signed integers, not unsigned. This is to be consistent with
7989 outgoing selection data, which was modified to use signed integers
7990 in as part of the fix to Bug#9196 in response to Jan D.'s comment
7991 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
7992 expects long, not unsigned long.
7994 2011-09-14 Eli Zaretskii <eliz@gnu.org>
7996 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
7997 computation of loop end. Reported by Johan Bockgård
7998 <bojohan@gnu.org>.
8000 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
8002 * frame.c (Fother_visible_frames_p): Function deleted.
8004 2011-09-12 Eli Zaretskii <eliz@gnu.org>
8006 * indent.c (compute_motion): Process display vector front to back
8007 rather than the other way around. (Bug#2496)
8009 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
8011 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
8013 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
8015 * minibuf.c (Fread_from_minibuffer): Doc fix.
8017 2011-09-11 Eli Zaretskii <eliz@gnu.org>
8019 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
8020 2011-08-30T17:32:44Z!eliz@gnu.org. (Bug#9475)
8022 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
8024 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
8025 value for non-existent files.
8027 2011-09-11 Eli Zaretskii <eliz@gnu.org>
8029 * fileio.c (Finsert_file_contents): If the file cannot be opened,
8030 set its "size" to -1. This will set the modtime_size field of
8031 the corresponding buffer to -1, which is what
8032 verify-visited-file-modtime expects for files that do not exist.
8033 (Bug#9139)
8035 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
8037 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
8038 here ...
8039 * lisp.h: ... from here. push_key_description is no longer
8040 defined in keyboard.c, so its declaration should not be in
8041 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
8042 logically belongs with push_key_description.
8044 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
8046 * buffer.h: Include <sys/types.h> instead of <time.h>.
8047 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
8048 Problem reported by Herbert J. Skuhra.
8050 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
8052 * xml.c (parse_region): Make the parsing work for
8053 non-comment-starting XML files again (bug#9144).
8055 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
8057 * image.c (gif_load): Fix calculation of bottom and right corner.
8058 (Bug#9468)
8060 2011-09-10 Eli Zaretskii <eliz@gnu.org>
8062 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
8063 redisplay in small windows.
8065 2011-09-09 Eli Zaretskii <eliz@gnu.org>
8067 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
8069 2011-09-08 Martin Rudalics <rudalics@gmx.at>
8071 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
8072 Operate on live windows only.
8074 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
8076 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
8078 2011-09-07 Eli Zaretskii <eliz@gnu.org>
8080 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
8081 only under bidi iteration.
8083 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
8085 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
8087 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
8089 isnan: Fix porting problem to Solaris 10 with bundled gcc.
8090 Without this fix, the command to link temacs failed due to an
8091 undefined symbol __builtin_isnan. This is because
8092 /usr/include/iso/math_c99.h #defines isnan(x) to
8093 __builtin_isnan(x), but the bundled gcc, which identifies itself
8094 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
8095 a __builtin_isnan.
8096 * floatfns.c (isnan): #undef, and then #define to a clone of
8097 what's in data.c.
8098 (Fisnan): Always define, since it's always available now.
8099 (syms_of_floatfns): Always define isnan at the Lisp level.
8101 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
8103 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
8105 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
8107 * fileio.c: Fix bugs with large file offsets (Bug#9428).
8108 The previous code assumed that file offsets (off_t values) fit in
8109 EMACS_INT variables, which is not true on typical 32-bit hosts.
8110 The code messed up by falsely reporting buffer overflow in cases
8111 such as (insert-file-contents "big" nil 1 2) into an empty buffer
8112 when "big" contains more than 2**29 bytes, even though this
8113 inserts just one byte and does not overflow the buffer.
8114 (Finsert_file_contents): Store file offsets as off_t
8115 values, not as EMACS_INT values. Check for overflow when
8116 converting between EMACS_INT and off_t. When checking for
8117 buffer overflow or for overlap, take the offsets into account.
8118 Don't use EMACS_INT for small values where int suffices.
8119 When checking for overlap, fix a typo: ZV was used where
8120 ZV_BYTE was intended.
8121 (Fwrite_region): Don't assume off_t fits into 'long'.
8122 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
8124 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
8126 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
8128 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
8130 sprintf-related integer and memory overflow issues (Bug#9412).
8132 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
8133 (esprintf, exprintf, evxprintf): New functions.
8134 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
8135 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
8136 (modify_event_symbol): Do not assume that the length of
8137 name_alist_or_stem is safe to alloca and fits in int.
8138 (Fexecute_extended_command): Likewise for function name and binding.
8139 (Frecursion_depth): Wrap around reliably on integer overflow.
8140 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
8141 since some callers pass EMACS_INT values.
8142 (Fsingle_key_description): Don't crash if symbol name contains more
8143 than MAX_ALLOCA bytes.
8144 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
8145 (get_minibuffer): Arg is now EMACS_INT, not int.
8146 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
8147 (esprintf, exprintf, evxprintf): New decls.
8148 * window.h (command_loop_level, minibuf_level): Reflect API changes.
8150 * dbusbind.c (signature_cat): New function.
8151 (xd_signature, Fdbus_register_signal):
8152 Do not overrun buffer; instead, report string overflow.
8154 * dispnew.c (add_window_display_history): Don't overrun buffer.
8155 Truncate instead; this is OK since it's just a log.
8157 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
8158 even if the time zone offset is outlandishly large.
8159 Don't mishandle offset == INT_MIN.
8161 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
8162 when creating daemon; the previous buffer-overflow check was incorrect.
8164 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
8165 which has the guts of the old verror function.
8167 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
8168 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
8170 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
8171 (font_unparse_xlfd): Don't blindly alloca long strings.
8172 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
8173 fits in int, when using sprintf. Use single snprintf to count
8174 length of string rather than counting it via multiple sprintfs;
8175 that's simpler and more reliable.
8176 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
8177 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
8178 sprintf, in case result does not fit in int.
8180 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
8181 (fontset_from_font): Print it.
8183 * frame.c (tty_frame_count): Now printmax_t, not int.
8184 (make_terminal_frame, set_term_frame_name): Print it.
8185 (x_report_frame_params): In X, window IDs are unsigned long,
8186 not signed long, so print them as unsigned.
8187 (validate_x_resource_name): Check for implausibly long names,
8188 and don't assume name length fits in 'int'.
8189 (x_get_resource_string): Don't blindly alloca invocation name;
8190 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
8191 not fit in int.
8193 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
8194 (xg_check_special_colors, xg_set_geometry):
8195 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
8197 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
8198 Use esprintf, not sprintf, in case result does not fit in int.
8200 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
8201 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
8202 it as a large positive number.
8203 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
8204 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
8206 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
8207 in case result does not fit in int.
8209 * print.c (float_to_string): Detect width overflow more reliably.
8210 (print_object): Make sprintf buffer a bit bigger, to avoid potential
8211 buffer overrun. Don't assume list length fits in 'int'. Treat
8212 print length of 0 as 0, not as infinity; to be consistent with other
8213 uses of print length in this function. Don't overflow print length
8214 index. Don't assume hash table size fits in 'long', or that
8215 vectorlike size fits in 'unsigned long'.
8217 * process.c (make_process): Use printmax_t, not int, to format
8218 process-name gensyms.
8220 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
8222 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
8223 to avoid potential buffer overrun.
8225 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
8226 if X resource line is longer than 512 bytes.
8228 * xfns.c (x_window): Make sprintf buffer a bit bigger
8229 to avoid potential buffer overrun.
8231 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
8233 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
8235 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
8237 Integer overflow fixes for scrolling, etc.
8238 Without these, Emacs silently mishandles large integers sometimes.
8239 For example, "C-u 4294967297 M-x recenter" was treated as if
8240 it were "C-u 1 M-x recenter" on a typical 64-bit host.
8242 * xdisp.c (try_window_id): Check Emacs fixnum range before
8243 converting to 'int'.
8245 * window.c (window_scroll_line_based, Frecenter):
8246 Check that an Emacs fixnum is in range before assigning it to 'int'.
8247 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
8248 values converted from Emacs fixnums.
8249 (Frecenter): Don't wrap around a line count if it is out of 'int'
8250 range; instead, treat it as an extreme value.
8251 (Fset_window_configuration, compare_window_configurations):
8252 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
8254 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
8255 that can exceed INT_MAX. Check that EMACS_INT value is in range
8256 before assigning it to the (possibly-narrower) index.
8257 (match_limit): Don't assume that a fixnum can fit in 'int'.
8259 * print.c (print_object): Use ptrdiff_t, not int, for index that can
8260 exceed INT_MAX.
8262 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
8263 (Fvertical_motion): Don't wrap around LINES values that don't fit
8264 in 'int'. Instead, treat them as extreme values. This is good
8265 enough for windows, which can't have more than INT_MAX lines anyway.
8267 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
8269 * Require libxml/parser.h to avoid compilation warning.
8271 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
8273 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
8274 since this reportedly can destroy thread storage.
8276 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
8278 * syntax.c (find_defun_start): Update all cache variables if
8279 exiting early (Bug#9401).
8281 2011-08-30 Eli Zaretskii <eliz@gnu.org>
8283 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
8285 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
8286 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
8287 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
8289 * term.c (tty_append_glyph): New function.
8290 (produce_stretch_glyph): Static function and its prototype deleted.
8292 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
8293 Add prototypes.
8295 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
8297 * image.c (parse_image_spec): Check for nonnegative, not for positive,
8298 when checking :margin (Bug#9390).
8299 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
8300 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
8301 so that the name doesn't mislead. All uses changed.
8303 2011-08-28 Johan Bockgård <bojohan@gnu.org>
8305 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
8306 set_tty_hooks.
8308 2011-08-27 Eli Zaretskii <eliz@gnu.org>
8310 * xdisp.c (move_it_to): Don't bail out early when reaching
8311 position beyond to_charpos, if we are scanning backwards.
8312 (move_it_vertically_backward): When DY == 0, make sure we get to
8313 the first character in the line after the newline.
8315 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
8317 * ccl.c: Improve and simplify overflow checking (Bug#9196).
8318 (ccl_driver): Do not generate an out-of-range pointer.
8319 (Fccl_execute_on_string): Remove unnecessary check for
8320 integer overflow, noted by Stefan Monnier in
8321 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
8322 Remove a FIXME that didn't need fixing.
8323 Simplify the newly-introduced buffer reallocation code.
8325 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
8327 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
8329 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
8331 Integer and memory overflow issues (Bug#9196).
8333 * doc.c (get_doc_string): Rework so that
8334 get_doc_string_buffer_size is the actual buffer size, rather than
8335 being 1 less than the actual buffer size; this makes xpalloc more
8336 convenient.
8338 * image.c (x_allocate_bitmap_record, cache_image):
8339 * xselect.c (Fx_register_dnd_atom):
8340 Simplify previous changes by using xpalloc.
8342 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
8343 since either will do and ptrdiff_t is convenient with xpalloc.
8345 * charset.c (charset_table_size)
8346 (struct charset_sort_data.priority): Now ptrdiff_t.
8347 (charset_compare): Don't overflow if priorities differ greatly.
8348 (Fsort_charsets): Don't assume list length fits in int.
8349 Check for size-calculation overflow when allocating sort data.
8350 (syms_of_charset): Allocate an initial charset table that is
8351 just under 64 KiB, to avoid problems with glibc malloc and mmap.
8353 * cmds.c (internal_self_insert): Check for size-calculation overflow.
8355 * composite.h (struct composition.glyph_len): Now int, not unsigned.
8356 The actual value is always <= INT_MAX, and leaving it unsigned made
8357 overflow checking harder.
8359 * dispextern.h (struct glyph_matrix.rows_allocated)
8360 (struct face_cache.size): Now ptrdiff_t, for convenience in use
8361 with xpalloc. The values are still always <= INT_MAX.
8363 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
8365 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
8366 (SAFE_NALLOCA): New macro.
8368 * region-cache.c (struct boundary.pos, find_cache_boundary)
8369 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
8370 (set_cache_region, invalidate_region_cache)
8371 (revalidate_region_cache, know_region_cache, region_cache_forward)
8372 (region_cache_backward, pp_cache):
8373 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
8374 so that ptrdiff_t * can be passed to xpalloc.
8375 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
8376 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
8377 (pp_cache): Don't assume cache_len fits in int.
8378 * region-cache.h: Adjust extern decls to match.
8380 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
8381 EMACS_INT, since either will do, for xpalloc.
8383 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
8384 (xnmalloc, xnrealloc, xpalloc): New functions.
8386 * bidi.c (bidi_shelve_header_size): New constant.
8387 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
8388 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
8390 * bidi.c (bidi_cache_shrink):
8391 * buffer.c (overlays_at, overlays_in, record_overlay_string)
8392 (overlay_strings):
8393 Don't update size of array until after memory allocation succeeds,
8394 because xmalloc/xrealloc may not return.
8395 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
8396 now that we have proper integer overflow checking.
8397 (record_overlay_string, overlay_strings): Catch overflows when
8398 calculating size of overlay_str_buf.
8400 * callproc.c (Fcall_process): Check for size overflow when
8401 calculating size of args2.
8402 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
8403 Normally we prefer signed values, but sticking with ptrdiff_t would
8404 require adding more-complicated checks.
8406 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
8407 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
8408 Redo buffer-overflow calculations to avoid integer overflow.
8409 Add a FIXME comment where memory seems to be over-allocated.
8411 * character.c (Fstring): Check for size-calculation overflow.
8413 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
8414 unnecessary integer overflow. Check for size overflow.
8415 (encode_coding_object): Don't update size until xmalloc succeeds.
8417 * composite.c (get_composition_id): Check for overflow in glyph
8418 length calculations.
8420 Integer and memory overflow fixes for display code.
8421 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
8422 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
8423 (scrolling_window): Check for overflow in size calculations.
8424 (line_draw_cost, realloc_glyph_pool, add_row_entry):
8425 Don't assume glyph table len fits in int.
8426 (struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
8427 (row_table_size): Now ptrdiff_t, not int.
8428 (scrolling_window): Avoid overflow in size calculations.
8429 Don't update size until allocation succeeds.
8430 * fns.c (concat): Check for overflow in size calculations.
8431 (next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
8432 * lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
8433 (NEXT_ALMOST_PRIME_LIMIT): New constant.
8435 * doc.c (get_doc_string_buffer_size): Now ptrdiff_t, not int.
8436 (get_doc_string): Check for size calculation overflow.
8437 Don't update size until allocation succeeds.
8438 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
8439 EMACS_INT, where ptrdiff_t will do.
8440 (Fsubstitute_command_keys): Check for string overflow.
8442 * editfns.c (set_time_zone_rule): Don't assume environment length
8443 fits in int.
8444 (message_length): Now ptrdiff_t, not int.
8445 (Fmessage_box): Don't update size until allocation succeeds.
8446 Don't assume message length fits in int.
8447 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
8449 * emacs.c (main): Do not reallocate argv, since there is a null at
8450 the end that can be overwritten, and this way there's no need to
8451 worry about size-calculation overflow.
8452 (sort_args): Check for size-calculation overflow.
8454 * eval.c (init_eval_once, grow_specpdl): Don't update size until
8455 alloc succeeds.
8456 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
8458 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
8459 (x_set_scroll_bar_width, x_figure_window_size):
8460 Check for integer overflow.
8461 (x_set_alpha): Do not assume XINT fits in int.
8463 * frame.h (struct frame): Use int, not EMACS_INT, where int works.

8474 Check for size-calculation overflow.
8475 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
8476 do, as we prefer signed integers.
8477 (id_to_widget.max_size, id_to_widget.used)
8478 (xg_store_widget_in_map, xg_remove_widget_from_map)
8479 (xg_get_widget_from_map, xg_get_scroll_id_for_window)

8530 (Fset_match_data): Don't assume list lengths fit in 'int'.
8532 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
8533 for command line length. Do not attempt to address one before the
8534 beginning of an array, as that's not portable.

8562 Use ptrdiff_t, not int, for sizes.
8563 (Finternal_make_lisp_face, cache_face):
8564 Check for size calculation overflow.
8565 (cache_face): Treat size calculation overflows as if they were
8566 memory exhaustion (the usual treatment), rather than aborting.
8568 * xfns.c (x_encode_text, x_set_name_internal)
8569 (Fx_change_window_property): Use ptrdiff_t, not int, to count
8570 sizes, since they can exceed INT_MAX in size. Check for size
8571 calculation overflow.
8573 * xgselect.c (gfds_size): Now ptrdiff_t, for convenience with xpalloc.
8574 (xg_select): Check for size calculation overflow.
8575 Don't update size until alloc done.
8577 * xrdb.c (get_environ_db): Don't assume path length fits in int,
8578 as sprintf is limited to int lengths.
8580 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
8581 (X_LONG_MIN): New macros.
8582 Use them to make the following changes clearer.
8583 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
8584 This change doesn't affect the value now, but it may help remind
8585 future maintainers not to raise the value too much later.
8586 (SELECTION_QUANTUM): Remove, replacing with ...
8587 (selection_quantum): ... new function, which avoids overflow.
8588 All uses changed.
8589 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
8590 assumption that selection length fits in 'int'.

8592 (x_get_window_property, receive_incremental_selection)
8593 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)

8597 (receive_incremental_selection, x_property_data_to_lisp):
8598 Redo calculations to avoid overflow.
8599 (x_reply_selection_request): When sending hint, ceiling it at
8600 X_LONG_MAX rather than relying on wraparound overflow to send
8601 something.
8602 (x_get_window_property, receive_incremental_selection)
8603 (lisp_data_to_selection_data, x_property_data_to_lisp):

8607 Don't store size until memory allocation succeeds.
8608 (x_get_window_property): Plug memory leak on memory exhaustion.
8609 Don't double-block input; malloc is safe here. Don't assume 2**34
8610 - 4 fits in unsigned long. Add an xassert to check
8611 XGetWindowProperty overflow. Be more careful about overflow
8612 calculations, and distinguish size from memory overflow better.
8613 (receive_incremental_selection): When tracing, don't assume
8614 unsigned int is less than INT_MAX.
8615 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory
8616 harmful) conversions of unsigned short to int.
8617 (lisp_data_to_selection_data): Don't assume that integers
8618 in the range -65535 through -1 fit in an X unsigned short.
8619 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
8620 result parameters unless successful. Rely on cons_to_unsigned
8621 to report problems with elements; the old code wasn't right anyway.
8622 (x_check_property_data): Check for int overflow; we cannot use
8623 a wider type due to X limits.
8624 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
8626 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.

8655 * image.c (xpm_get_color_table_h):
8656 * lisp.h (hash_lookup, hash_put):
8657 * minibuf.c (Ftest_completion):
8658 Use ptrdiff_t for hash table indexes, not int (which is too
8659 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
8660 32-bit --with-wide-int hosts).
8662 * charset.c (Fdefine_charset_internal): Check for integer overflow.
8663 Add a FIXME comment about memory leaks.
8664 (syms_of_charset): Don't assume xmalloc returns.
8666 Don't assume that stated character widths fit in int.

8668 * character.h (CHAR_WIDTH):
8669 * indent.c (MULTIBYTE_BYTES_WIDTH):
8670 Use sanitize_char_width to avoid undefined and/or bad behavior
8671 with outlandish widths.
8672 * character.h (sanitize_tab_width): Rename from sanitize_width,
8673 now that we have two such functions. All uses changed.
8674 (sanitize_char_width): New inline function.
8676 Don't assume that tab-width fits in int.
8677 * character.h (sanitize_width): New inline function.
8678 (SANE_TAB_WIDTH): New macro.

8693 (x_send_scroll_bar_event): Likewise. Check that the size does not
8694 exceed limits imposed by XClientMessageEvent, as well as the usual
8695 ptrdiff_t and size_t limits.
8697 * keyboard.c: Overflow, signedness and related fixes.
8698 (make_lispy_movement): Use same integer type in forward decl
8699 that is used in the definition.
8700 (read_key_sequence, keyremap_step):
8701 Change bufsize argument back to int, undoing my 2011-03-30 change.
8702 We prefer signed types, and int is wide enough here.
8703 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
8704 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
8705 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
8706 length, not size_t. Use ptrdiff_t for index, not int.
8707 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
8708 possibility of integer overflow.
8710 Overflow, signedness and related fixes for images.

8720 * xdisp.c (calc_pixel_width_or_height):
8721 * xfns.c (image_cache_refcount):
8722 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
8723 on typical 64-bit hosts.
8725 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
8726 (x_bitmap_pixmap, x_create_x_image_and_pixmap):

8731 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
8732 (lookup_image): Remove unnecessary tests.
8733 (xbm_image_p): Locals are now of int, not EMACS_INT,
8734 since parse_image_check makes sure they fit into int.
8735 (png_load, gif_load, svg_load_image):
8736 Prefer int to unsigned where either will do.
8737 (tiff_handler): New function, combining the cores of the
8738 old tiff_error_handler and tiff_warning_handler.
8739 This function is rewritten to use vsnprintf and thereby avoid
8740 stack buffer overflows. It uses only the features of vsnprintf
8741 that are common to both POSIX and native Microsoft.
8742 (tiff_error_handler, tiff_warning_handler): Use it.
8743 (tiff_load, gif_load, imagemagick_load_image):
8744 Don't assume :index value fits in 'int'.
8745 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
8746 (imagemagick_load_image): Check that crop parameters fit into
8747 the integer types that MagickCropImage accepts. Don't assume
8748 Vimagemagick_render_type has a nonnegative value. Don't assume
8749 size_t fits in 'long'.
8750 (gs_load): Use printmax_t to print the widest integers possible.
8751 Check for integer overflow when computing image height and width.
8753 2011-08-26 Eli Zaretskii <eliz@gnu.org>
8755 * xdisp.c (redisplay_window): Don't force window start if point
8756 will be invisible in the resulting window. (Bug#9324)

8760 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
8761 the display spec is of the form `(space ...)'.

8763 handle_single_display_spec, not just 1 or zero.
8764 (handle_single_display_spec): If the display spec is of the form
8765 `(space ...)', and specifies display in the text area, return 2
8766 rather than 1.
8767 (try_cursor_movement): Check for the need to scroll more
8768 accurately, and prefer exact match for point under bidi.
8769 Don't advance `row' beyond the last row of the window.
8771 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
8772 into disp_prop; all users changed.
8774 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns

8787 buffers, return left-to-right.
8788 (set_cursor_from_row): Consider candidate row a win if its glyph
8789 represents a newline and point is on that newline. Fixes cursor
8790 positioning on the newline at EOL of R2L text within L2R
8791 paragraph, and vice versa.
8792 (try_cursor_movement): Check continued rows, in addition to
8793 continuation rows. Fixes unwarranted scroll when point enters a
8794 continued line of R2L text within an L2R paragraph, or vice versa.
8795 (cursor_row_p): Consider the case of point being equal to
8796 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
8797 from the end of a short line to the beginning of a continued line
8798 of R2L text within L2R paragraph.
8799 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for

8822 * xdisp.c (redisplay_window): When computing centering_position,
8823 account for the height of the header line. (Bug#8874)
8825 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
8826 instead of CHAR_TO_BYTE. Fixes a crash when a completion
8827 candidate is selected by the mouse, and that candidate has a
8828 composed character under the mouse.
8830 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
8831 coordinates reported by pos-visible-in-window-p for a composed
8832 character in column zero.

8838 2011-08-22 Eli Zaretskii <eliz@gnu.org>
8840 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
8841 consider it a hit if to_charpos is anywhere in the range of the
8842 composed buffer positions.
8844 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
8846 * image.c (gif_load): Don't assume that each subimage has the same
8847 dimensions as the base image. Handle disposal method that is
8848 "undefined" by the gif spec (Bug#9335).
8850 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
8852 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
8853 (Fcondition_case): Document `debug' symbol in error handler.
8855 2011-08-19 Eli Zaretskii <eliz@gnu.org>
8857 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
8858 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
8859 from an Org mode buffer to a Speedbar frame.
8861 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
8862 a composition, take its buffer position from IT->cmp_it.charpos.
8863 Fixes cursor positioning at the beginning of a line that begins
8864 with a composed character.
8866 2011-08-18 Eli Zaretskii <eliz@gnu.org>
8868 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
8869 character bidirectional type, use STRONG_L instead. Fixes crashes
8870 in a buffer produced by `describe-categories'.
8872 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
8873 members before the level stack, so they would be saved and
8874 restored when copying iterator state. Fixes incorrect reordering
8875 around TABs covered by display properties.
8877 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
8879 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

8911 dumped emacs.
8912 (_free_internal_nolock) [CYGWIN]: Ignore requests to free storage
8913 in the static heap.
8914 [CYGWIN] (special_realloc): New function.
8915 (_realloc_internal_nolock) [CYGWIN]: Use the new function on
8916 requests to realloc storage in the static heap.
8918 2011-08-15 Paul Eggert <eggert@cs.ucla.edu>
8920 * bidi.c (bidi_initialize): Remove unused local.
8922 2011-08-15 Eli Zaretskii <eliz@gnu.org>
8924 * bidimirror.h:
8925 * biditype.h: Remove file.
8926 * makefile.w32-in ($(BLD)/bidi.$(O)):
8927 * deps.mk (bidi.o): Remove biditype.h and bidimirror.h.
8929 * dispextern.h: Fix a typo in the comment to bidi_type_t.
8931 * chartab.c: Improve commentary for the uniprop_table API.
8933 * bidi.c (bidi_paragraph_init): Support zero value of
8934 bidi_ignore_explicit_marks_for_paragraph_level.
8935 (bidi_initialize): Use uniprop_table instead of including
8936 biditype.h and bidimirror.h.
8938 * xdisp.c (move_it_in_display_line_to): Don't reset pixel
8939 coordinates of the iterator when restoring from ppos_it.
8940 (Bug#9296)
8942 2011-08-14 Kenichi Handa <handa@m17n.org>
8944 * process.c (create_process): Call setup_process_coding_systems
8945 after the pid of the process is set to -1 (Bug#8162).
8947 2011-08-14 Eli Zaretskii <eliz@gnu.org>
8949 * xdisp.c (move_it_in_display_line_to): Don't invoke
8950 IT_RESET_X_ASCENT_DESCENT when iterator position was restored from
8951 ppos_it. Fixes vertical cursor motion when line beginning is
8952 covered by an image. (Bug#9296)
8954 2011-08-14 Jan Djärv <jan.h.d@swipnet.se>
8956 * nsterm.h (ns_run_ascript): Declare.
8957 (NSAPP_DATA2_RUNASSCRIPT): Define.
8959 * nsfns.m (as_script, as_result, as_status): New static variables.
8960 (ns_run_ascript): New function.
8961 (Fns_do_applescript): Set variables as_*. Make an NSApplicationDefined
8962 event with data2 set to NSAPP_DATA2_RUNASSCRIPT, post it and then start
8963 the event loop. Get status from as_status (Bug#7276).
8965 * nsterm.m (sendEvent): If event is NSApplicationDefined and
8966 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
8967 the event loop (Bug#7276).
8969 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>
8971 * gnutls.c (QCgnutls_bootprop_priority)
8972 (QCgnutls_bootprop_trustfiles, QCgnutls_bootprop_keylist)
8973 (QCgnutls_bootprop_crlfiles, QCgnutls_bootprop_callbacks)
8974 (QCgnutls_bootprop_loglevel, QCgnutls_bootprop_hostname)
8975 (QCgnutls_bootprop_min_prime_bits, QCgnutls_bootprop_verify_flags)
8976 (QCgnutls_bootprop_verify_hostname_error)
8977 (QCgnutls_bootprop_callbacks_verify): Rename from
8978 Qgnutls_bootprop_..., all uses changed.
8980 * xfaces.c (QCignore_defface): Rename from Qignore_defface, all
8981 uses changed.
8983 2011-08-14 Paul Eggert <eggert@cs.ucla.edu>
8985 * xfaces.c (Qframe_set_background_mode): Now static.
8986 * dispextern.h (Qframe_set_background_mode): Remove decl.
8988 * process.c (Fnetwork_interface_info): Declare local only if needed.
8990 2011-08-13 Jan Djärv <jan.h.d@swipnet.se>
8992 * process.c: Include ifaddrs.h and net/if_dl.h if available (Bug#8477).
8993 (Fnetwork_interface_list): Allocate in increments of bytes instead
8994 of sizeof (struct ifreq). Iterate over ifconf.ifc_req by counting
8995 bytes (Bug#8477). Count bytes correctly when ifr_addr is a struct
8996 sockaddr.
8997 (struct ifflag_def): notrailers is smart on OSX.
8998 (Fnetwork_interface_info): Handle case when ifr_flags is negative.
8999 Get hardware address with getifaddrs if available.
9001 2011-08-12 Eli Zaretskii <eliz@gnu.org>
9003 * xdisp.c (iterate_out_of_display_property): xassert that
9004 IT->position is set to within IT->object's boundaries. Break from
9005 the loop as soon as EOB is reached; avoids infloops in redisplay
9006 when IT->position is set up wrongly due to some bug.
9007 Set IT->current to match the bidi iterator unconditionally.
9008 (push_display_prop): Allow GET_FROM_STRING as IT->method on
9009 entry. Force push_it to save on the stack the current
9010 buffer/string position, to be restored by pop_it. Fix flags in
9011 the iterator structure wrt the object coming from a display
9012 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
9013 properties. (Bug#9284)
9015 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
9017 * fontset.c (fontset_get_font_group): Add proper type checks.
9018 (Bug#9172)
9020 2011-08-09 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
9022 * unexmacosx.c (print_load_command_name): Add cases LC_FUNCTION_STARTS
9023 and LC_VERSION_MIN_MACOSX.
9024 (copy_linkedit_data) [LC_FUNCTION_STARTS]: New function.
9025 (dump_it) [LC_FUNCTION_STARTS]: Use it.
9027 2011-08-08 Eli Zaretskii <eliz@gnu.org>
9029 * xdisp.c (forward_to_next_line_start): Allow to use the
9030 no-display-properties-and-no-overlays under bidi display.
9031 Set disp_pos in the bidi iterator to avoid searches for display
9032 properties and overlays.
9034 2011-08-08 Chong Yidong <cyd@stupidchicken.com>
9036 * editfns.c (Fset_time_zone_rule): Document relationship with the
9037 setenv function.
9039 * ftfont.c (ftfont_pattern_entity): Copy the extras argument to
9040 the font entity extracted from the cache (Bug#8109).
9042 2011-08-07 Chong Yidong <cyd@stupidchicken.com>
9044 * composite.c (autocmp_chars): Don't reset point. That is done by
9045 restore_point_unwind (Bug#5984).
9047 2011-08-07 Juri Linkov <juri@jurta.org>
9049 * editfns.c (Fformat_time_string): Doc fix, add tag `usage:'
9050 to show the arg `TIME' instead of `TIMEVAL'.
9052 2011-08-06 Eli Zaretskii <eliz@gnu.org>
9054 * xdisp.c (set_cursor_from_row): Fix cursor positioning when a
9055 display property strides EOL and includes a newline, as in
9056 longlines-mode. (Bug#9254)
9057 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
9058 word-wrap under bidirectional display. (Bug#9224)
9060 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
9061 is non-zero, even if the data buffer is NULL. Fixes a crash in
9062 vertical-motion with longlines-mode. (Bug#9254)
9064 2011-08-05 Eli Zaretskii <eliz@gnu.org>
9066 * bidi.c <bidi_cache_total_alloc>: Now static.
9067 (bidi_initialize): Initialize bidi_cache_total_alloc.
9069 * xdisp.c (display_line): Release buffer allocated for shelved bidi
9070 cache. (Bug#9221)
9072 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
9073 amount allocated this far in `bidi_cache_total_alloc'.
9074 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if
9075 non-zero, only free the data buffer without restoring the cache
9076 contents. All callers changed.
9078 * dispextern.h (bidi_unshelve_cache): Update prototype.
9080 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)
9081 (move_it_in_display_line, move_it_to)
9082 (move_it_vertically_backward, move_it_by_lines): Replace the call
9083 to xfree to an equivalent call to bidi_unshelve_cache.
9084 (move_it_in_display_line_to): Fix logic of returning
9085 MOVE_POS_MATCH_OR_ZV in the bidi case. (Bug#9224)
9087 2011-08-05 Eli Zaretskii <eliz@gnu.org>
9089 * xdisp.c (set_cursor_from_row): Prefer the candidate glyph that
9090 came from a string character with a `cursor' property. (Bug#9229)
9092 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
9094 * Makefile.in (LIB_PTHREAD): New variable.
9095 (LIBES): Add LIB_PTHREAD (Bug#9216).
9097 * alloc.c, emacs.c, gmalloc.c, gtkutil.c, keyboard.c, syssignal.h:
9098 Rename HAVE_GTK_AND_PTHREAD to HAVE_PTHREAD (Bug#9216).
9100 2011-08-04 Andreas Schwab <schwab@linux-m68k.org>
9102 * regex.c (re_iswctype): Remove some redundant boolean conversions.
9104 2011-08-04 Jan Djärv <jan.h.d@swipnet.se>
9106 * xterm.c (x_find_topmost_parent): New function.
9107 (x_set_frame_alpha): Find topmost parent window with
9108 x_find_topmost_parent and set the property there also (bug#9181).
9109 (handle_one_xevent): Call x_set_frame_alpha on ReparentNotify.
9111 2011-08-04 Paul Eggert <eggert@cs.ucla.edu>
9113 * callproc.c (Fcall_process): Avoid vfork clobbering
9114 the local vars buffer, coding_systems, current_dir.
9116 2011-08-03 Stefan Monnier <monnier@iro.umontreal.ca>
9118 * keymap.c (Fmake_composed_keymap): Move to subr.el.
9120 2011-08-03 Paul Eggert <eggert@cs.ucla.edu>
9122 * fontset.c (dump_fontset) [FONTSET_DEBUG]: Declare EXTERNALLY_VISIBLE
9123 so that it is not optimized away.
9125 * xdisp.c (compute_display_string_pos): Remove unused local.
9127 2011-08-02 Eli Zaretskii <eliz@gnu.org>
9129 Fix slow cursor motion and scrolling in large buffers with
9130 selective display, like Org Mode buffers. (Bug#9218)
9132 * dispextern.h (struct bidi_it): New member disp_prop_p.
9134 * xdisp.c: Remove one-slot cache of display string positions.
9135 (compute_display_string_pos): Accept an additional argument
9136 DISP_PROP_P; callers changed. Scan at most 5K characters forward
9137 for a display string or property. If found, set DISP_PROP_P
9138 non-zero.
9140 * bidi.c (bidi_fetch_char): Accept an additional argument
9141 DISP_PROP_P, and pass it to compute_display_string_pos.
9142 Only handle text covered by a display string if DISP_PROP_P is returned
9143 non-zero. All callers of bidi_fetch_char changed.
9145 2011-08-02 Stefan Monnier <monnier@iro.umontreal.ca>
9147 * keymap.c (Fdefine_key): Fix Lisp_Object/int mixup; apply some CSE.
9149 2010-12-03 Don March <don@ohspite.net>
9151 * keymap.c (Fdefine_key): Fix non-prefix key error message when
9152 last character M-[char] is translated to ESC [char] (bug#7541).
9154 2011-08-02 Kenichi Handa <handa@m17n.org>
9156 * lisp.h (uniprop_table): Extern it.
9158 * chartab.c (uniprop_table): Make it non-static.
9160 2011-08-01 Eli Zaretskii <eliz@gnu.org>
9162 * xdisp.c (forward_to_next_line_start): Accept additional argument
9163 BIDI_IT_PREV, and store into it the state of the bidi iterator had
9164 on the newline.
9165 (reseat_at_next_visible_line_start): Use the bidi iterator state
9166 returned by forward_to_next_line_start to restore the state of
9167 it->bidi_it after backing up to previous newline. (Bug#9212)
9169 2011-07-30 Andreas Schwab <schwab@linux-m68k.org>
9171 * regex.c (re_comp): Protoize.
9172 (re_exec): Fix return type.
9173 (regexec): Fix type of `ret'. (Bug#9203)
9175 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
9177 * image.c (check_image_size): Use 1024x1024 if unknown frame (Bug#9189).
9178 This is needed if max-image-size is a floating-point number.
9180 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
9182 * print.c (print_object): Print empty symbol as ##.
9184 * lread.c (read1): Read ## as empty symbol.
9186 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
9188 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
9189 setting frame foreground color (Bug#9175).
9190 (x_set_background_color): Likewise.
9192 * nsmenu.m (-setText): Size tooltip dimensions precisely to
9193 contents (Bug#9176).
9194 (EmacsTooltip -init): Remove bezels and add shadows to
9195 tooltip windows.
9197 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
9198 or scroll bar (Bug#8470).
9200 * nsfont.m (nsfont_open): Remove assignment to voffset and
9201 unnecessary vars hshink, expand, hd, full_height, min_height.
9202 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
9204 * nsterm.h (nsfont_info): Remove voffset field.
9206 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
9208 Implement strike-through and overline on NextStep (Bug#8863).
9210 * nsfont.m (nsfont_open): Use underline position provided by font,
9211 instead of hard-coded value of 2.
9212 (nsfont_draw): Call ns_draw_text_decoration instead.
9214 * nsterm.h: Add declaration for ns_draw_text_decoration.
9216 * nsterm.m (ns_draw_text_decoration): New function for drawing
9217 underline, overline, and strike-through.
9218 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
9219 ns_draw_text_decoration. Change treatment of cursor drawing to
9220 accommodate underlining, etc.
9222 2011-07-28 Eli Zaretskii <eliz@gnu.org>
9224 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
9225 default.
9227 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
9229 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
9230 Without this fix, if a signal arrives just after memory fills up,
9231 'malloc' might be invoked reentrantly.
9233 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
9234 In other words, assume that every image size is allowed, on non-X
9235 hosts. This assumption is probably wrong, but it lets Emacs compile.
9237 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
9239 * regex.c (re_iswctype): Convert return values to boolean.
9241 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
9243 * xdisp.c (compute_display_string_pos): Don't use cached display
9244 string position if the buffer had its restriction changed.
9245 (Bug#9184)
9247 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
9249 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
9251 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
9253 Integer signedness and overflow and related fixes. (Bug#9079)
9255 * bidi.c: Integer size and overflow fixes.
9256 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
9257 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
9258 (bidi_cache_find_level_change, bidi_cache_ensure_space)
9259 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
9260 (bidi_find_other_level_edge):
9261 Use ptrdiff_t instead of EMACS_INT where either will do.
9262 This works better on 32-bit hosts configured --with-wide-int.
9263 (bidi_cache_ensure_space): Check for size-calculation overflow.
9264 Use % rather than repeated addition, for better worst-case speed.
9265 Don't set bidi_cache_size until after xrealloc returns, because it
9266 might not return.
9267 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
9268 (bidi_cache_ensure_space): Also check that the bidi cache size
9269 does not exceed that of the largest Lisp string or buffer. See Eli
9270 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
9272 * alloc.c (__malloc_size_t): Remove.
9273 All uses replaced by size_t. See Andreas Schwab's note
9274 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
9276 * image.c: Improve checking for integer overflow.
9277 (check_image_size): Assume that f is nonnull, since
9278 it is always nonnull in practice. This is one less thing to
9279 worry about when checking for integer overflow later.
9280 (x_check_image_size): New function, which checks for integer
9281 overflow issues inside X.
9282 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
9283 This removes the need for a memory_full check.
9284 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
9285 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
9286 (xbm_read_bitmap_data): Change locals back to 'int', since
9287 their values must fit in 'int'.
9288 (xpm_load_image, png_load, tiff_load):
9289 Invoke x_create_x_image_and_pixmap earlier,
9290 to avoid much needless work if the image is too large.
9291 (tiff_load): Treat overly large images as if
9292 x_create_x_image_and_pixmap failed, not as malloc failures.
9293 (gs_load): Use x_check_image_size.
9295 * gtkutil.c: Omit integer casts.
9296 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
9297 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
9299 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
9301 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
9302 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
9303 would wrongly return t on a 64-bit host.
9305 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
9306 The plain *_OVERFLOW macros run afoul of GCC bug 49705
9307 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
9308 and therefore cause GCC to emit a bogus diagnostic in some cases.
9310 * image.c: Integer signedness and overflow and related fixes.
9311 This is not an exhaustive set of fixes, but it's time to
9312 record what I've got.
9313 (lookup_pixel_color, check_image_size): Remove redundant decls.
9314 (check_image_size): Don't assume that arbitrary EMACS_INT values
9315 fit in 'int', or that arbitrary 'double' values fit in 'int'.
9316 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
9317 (tiff_load, imagemagick_load_image):
9318 Check for overflow in size calculations.
9319 (x_create_x_image_and_pixmap): Remove unnecessary test for
9320 xmalloc returning NULL; that can't happen.
9321 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
9322 (xpm_color_bucket): Use better integer hashing function.
9323 (xpm_cache_color): Don't possibly over-allocate memory.
9324 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
9325 (gif_memory_source):
9326 Use ptrdiff_t, not int or size_t, to record sizes.
9327 (png_load): Don't assume values greater than 2**31 fit in 'int'.
9328 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
9329 either works, as we prefer signed integers.
9330 (tiff_read_from_memory, tiff_write_from_memory):
9331 Return tsize_t, not size_t, since that's what the TIFF API wants.
9332 (tiff_read_from_memory): Don't fail simply because the read would
9333 go past EOF; instead, return a short read.
9334 (tiff_load): Omit no-longer-needed casts.
9335 (Fimagemagick_types): Don't assume size fits into 'int'.
9337 Improve hashing quality when configured --with-wide-int.
9338 * fns.c (hash_string): New function, taken from sxhash_string.
9339 Do not discard information about ASCII character case; this
9340 discarding is no longer needed.
9341 (sxhash-string): Use it. Change sig to match it. Caller changed.
9342 * lisp.h: Declare it.
9343 * lread.c (hash_string): Remove, since we now use fns.c's version.
9344 The fns.c version returns a wider integer if --with-wide-int is
9345 specified, so this should help the quality of the hashing a bit.
9347 * emacs.c: Integer overflow minor fix.
9348 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
9349 Define only if GNU_LINUX.
9350 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
9352 * dispnew.c: Integer signedness and overflow fixes.
9353 Remove unnecessary forward decls, that were a maintenance hassle.
9354 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
9355 All uses changed.
9356 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
9357 (scrolling_window): Use ptrdiff_t, not int, for byte count.
9358 (prepare_desired_row, line_draw_cost):
9359 Use int, not unsigned, where either works.
9360 (save_current_matrix, restore_current_matrix):
9361 Use ptrdiff_t, not size_t, where either works.
9362 (init_display): Check for overflow more accurately, and without
9363 relying on undefined behavior.
9365 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
9366 Remove, replacing with the new symbols in lisp.h. All uses changed.
9367 * fileio.c (make_temp_name):
9368 * filelock.c (lock_file_1, lock_file):
9369 * xdisp.c (message_dolog):
9370 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
9371 Use pMd etc. instead.
9372 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
9373 replacing the pWIDE etc. symbols removed from editfns.c.
9375 * keyboard.h (num_input_events): Now uintmax_t.
9376 This is (very slightly) less likely to mess up due to wraparound.
9377 All uses changed.
9379 * buffer.c: Integer signedness fixes.
9380 (alloc_buffer_text, enlarge_buffer_text):
9381 Use ptrdiff_t rather than size_t when either will do, as we prefer
9382 signed integers.
9384 * alloc.c: Integer signedness and overflow fixes.
9385 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
9386 (__malloc_size_t): Default to size_t, not to int.
9387 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
9388 (Fgarbage_collect, mark_object_loop_halt, mark_object):
9389 Prefer ptrdiff_t to size_t when either would do, as we prefer
9390 signed integers.
9391 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
9392 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
9393 Now const. Initialize with values that are in range even if char
9394 is signed.
9395 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
9396 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
9397 These functions do the right thing with sizes > 2**32.
9398 (check_depth): Now ptrdiff_t, not int.
9399 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
9400 Adjust to new way of storing sizes. Check for size overflow bugs
9401 in rest of code.
9402 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
9403 slightly wrong anyway, as it missed one instance of
9404 XMALLOC_OVERRUN_CHECK_OVERHEAD.
9405 (refill_memory_reserve): Omit needless cast to size_t.
9406 (mark_object_loop_halt): Mark as externally visible.
9408 * xselect.c: Integer signedness and overflow fixes.
9409 (Fx_register_dnd_atom, x_handle_dnd_message):
9410 Use ptrdiff_t, not size_t, since we prefer signed.
9411 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
9412 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
9413 x_dnd_atoms_size and x_dnd_atoms_length.
9415 * doprnt.c: Prefer signed to unsigned when either works.
9416 * eval.c (verror):
9417 * doprnt.c (doprnt):
9418 * lisp.h (doprnt):
9419 * xdisp.c (vmessage):
9420 Use ptrdiff_t, not size_t, when using or implementing doprnt,
9421 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
9422 prefer signed arithmetic to avoid comparison confusion.
9423 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
9424 but is a bit tricky.
9426 Assume freestanding C89 headers, string.h, stdlib.h.
9427 * data.c, doprnt.c, floatfns.c, print.c:
9428 Include float.h unconditionally.
9429 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
9430 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
9431 * regex.c: Likewise for stddef.h, string.h.
9432 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
9433 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
9434 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
9435 (STDC_HEADERS): Remove obsolete defines.
9436 * sysdep.c: Include limits.h unconditionally.
9438 Assume support for memcmp, memcpy, memmove, memset.
9439 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
9440 * regex.c (memcmp, memcpy):
9441 Remove; we assume C89 now.
9443 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
9444 (__malloc_safe_bcopy): Remove; no longer needed.
9446 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
9447 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
9448 well either way, and we prefer signed to unsigned.
9450 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
9452 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
9453 closes the connection while we're reading (bug#9182).
9455 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
9457 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
9458 are specified (Bug#9168).
9460 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
9462 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
9463 Found by GCC static checking and --with-wide-int on a 32-bit host.
9465 2011-07-25 Eli Zaretskii <eliz@gnu.org>
9467 * xdisp.c (compute_display_string_pos): Fix logic of caching
9468 previous display string position. Initialize cached_prev_pos to
9469 -1. Fixes slow-down at the beginning of a buffer.
9471 2011-07-24 Eli Zaretskii <eliz@gnu.org>
9473 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
9474 for attrs[LFACE_FONTSET_INDEX].
9476 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
9478 * xml.c (parse_region): Remove unused local
9479 that was recently introduced.
9481 2011-07-23 Eli Zaretskii <eliz@gnu.org>
9483 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
9484 2008-02-22T17:42:09Z!monnier@iro.umontreal.ca.
9486 * xdisp.c (move_it_in_display_line_to): Record the best matching
9487 position for TO_CHARPOS while scanning the line, and restore it on
9488 exit if none of the characters scanned was an exact match.
9489 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
9490 when exact match is impossible due to invisible text, and the
9491 lines are truncated.
9493 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
9495 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
9496 for OSX >= 10.7.
9498 2011-07-22 Eli Zaretskii <eliz@gnu.org>
9500 Fix a significant slow-down of cursor motion with C-n, C-p,
9501 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
9502 auto-repeat under bidi redisplay in fontified buffers.
9503 * xdisp.c (compute_stop_pos_backwards): New function.
9504 (next_element_from_buffer): Call compute_stop_pos_backwards to
9505 find a suitable prev_stop when we find ourselves before
9506 base_level_stop.
9507 (reseat): Don't look for prev_stop, as that could mean a very long
9508 run.
9509 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
9510 <cached_disp_overlay_modiff>: Cache for last found display string
9511 position.
9512 (compute_display_string_pos): Return the cached position if asked
9513 about the same buffer in the same area of character positions, and
9514 the buffer wasn't changed since the time the display string
9515 position was cached.
9517 2011-07-22 Eli Zaretskii <eliz@gnu.org>
9519 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
9520 is an integer, which is important for empty lines. (Bug#9149)
9522 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
9524 * frame.c (Fmodify_frame_parameters): In tty case, update the
9525 default face if necessary (Bug#4238).
9527 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
9529 * editfns.c (Fstring_to_char): No need to explain what a character
9530 is in the docstring (Bug#6576).
9532 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
9534 * xml.c (parse_region): Make sure we always return a tree.
9536 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
9538 * xml.c (parse_region): If a document contains only comments,
9539 return that, too.
9541 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
9543 * xml.c (make_dom): Return comments, too.
9545 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
9547 Port to OpenBSD.
9548 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
9549 and the surrounding thread.
9550 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
9551 rather than fgets, and retry after EINTR. Otherwise, 'emacs
9552 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
9553 timer goes off.
9554 * s/openbsd.h (BROKEN_SIGIO): Define.
9555 * unexelf.c (unexec) [__OpenBSD__]:
9556 Don't update the .mdebug section of the Alpha COFF symbol table.
9558 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
9560 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
9561 (bug#8460).
9563 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
9565 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
9566 This fixes some race conditions on the permissions of any newly
9567 created file.
9569 * alloc.c (valid_pointer_p): Use pipe, not open.
9570 This fixes some permissions issues when debugging.
9572 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
9573 If fchown fails to set both uid and gid, try to set just gid,
9574 as that is sometimes allowed. Adjust the file's mode to eliminate
9575 setuid or setgid bits that are inappropriate if fchown fails.
9577 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
9579 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
9580 to compare Lisp_Objects.
9581 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
9582 global_gnutls_log_level, don't mistake it for a Lisp_Object.
9583 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
9585 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
9587 * lread.c (read_integer): Unread even EOF character.
9588 (read1): Likewise. Properly record start position of symbol.
9590 * lread.c (read1): Read `#:' as empty uninterned symbol if no
9591 symbol character follows.
9593 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
9595 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
9596 This works around a problem with the previous change to Fcopy_file.
9597 Recent glibc declares fchown with __attribute__((warn_unused_result)),
9598 and without this change, GCC might complain about discarding
9599 fchown's return value.
9601 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
9603 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
9605 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
9607 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
9609 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
9611 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
9612 it's used from the C level.
9614 * process.c: Use the same condition for POLL_FOR_INPUT in both
9615 keyboard.c and process.c (bug#1858).
9617 2011-07-09 Lawrence Mitchell <wence@gmx.li>
9619 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
9620 (Fgnutls_boot): Use it.
9622 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
9624 * doc.c (Fsubstitute_command_keys): Revert last change.
9626 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
9628 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
9629 quotes the next character, and doesn't affect other longer
9630 sequences (bug#8935).
9632 * lread.c (syms_of_lread): Clarify that is isn't only
9633 `eval-buffer' and `eval-defun' that's affected by
9634 `lexical-binding' (bug#8460).
9636 2011-07-15 Eli Zaretskii <eliz@gnu.org>
9638 * xdisp.c (move_it_in_display_line_to): Fix vertical motion with
9639 bidi redisplay when a line includes both an image and is truncated.
9641 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
9643 Fix minor problems found by static checking.
9644 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
9645 (elsz): Now a signed constant, not a size_t var. We prefer signed
9646 types to unsigned, to avoid integer comparison confusion. Without
9647 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
9648 "cannot optimize loop, the loop counter may overflow", a symptom
9649 of the confusion.
9650 * indent.c (Fvertical_motion): Mark locals as initialized.
9651 * xdisp.c (reseat_to_string): Fix pointer signedness issue.
9653 2011-07-14 Lars Magne Ingebrigtsen <larsi@gnus.org>
9655 * search.c (Fre_search_backward): Mention `case-fold-search' in
9656 all the re_search_* functions (bug#8138).
9658 * keyboard.c (Fopen_dribble_file): Document when the file is
9659 closed (bug#8056).
9661 2011-07-14 Eli Zaretskii <eliz@gnu.org>
9663 * bidi.c (bidi_dump_cached_states): Fix format of displaying
9664 bidi_cache_idx.
9666 Support bidi reordering of display and overlay strings.
9667 * xdisp.c (compute_display_string_pos)
9668 (compute_display_string_end): Accept additional argument STRING.
9669 (init_iterator, reseat_1): Initialize bidi_it->string.s to NULL.
9670 (reseat_to_string): Initialize bidi_it->string.s and
9671 bidi_it->string.schars.
9672 (Fcurrent_bidi_paragraph_direction): Initialize itb.string.s to
9673 NULL (avoids a crash in bidi_paragraph_init).
9674 Initialize itb.string.lstring.
9675 (init_iterator): Call bidi_init_it only of a valid
9676 buffer position was specified. Initialize paragraph_embedding to
9677 L2R.
9678 (reseat_to_string): Initialize the bidi iterator.
9679 (display_string): If we need to ignore text properties of
9680 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
9681 original value of -1 will not work with bidi.)
9682 (compute_display_string_pos): First arg is now struct
9683 `text_pos *'; all callers changed. Support display properties on
9684 Lisp strings.
9685 (compute_display_string_end): Support display properties on Lisp
9686 strings.
9687 (init_iterator, reseat_1, reseat_to_string): Initialize the
9688 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
9689 when iterating on a string not from display properties).
9690 (compute_display_string_pos, compute_display_string_end):
9691 Fix calculation of the object to scan. Fixes an error when using
9692 arrow keys.
9693 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
9694 base_level_stop; instead, set base_level_stop to BEGV.
9695 Fixes crashes in vertical-motion.
9696 (next_element_from_buffer): Improve commentary for when
9697 the iterator is before prev_stop.
9698 (init_iterator): Initialize bidi_p from the default value of
9699 bidi-display-reordering, not from buffer-local value. Use the
9700 buffer-local value only if initializing for buffer iteration.
9701 (handle_invisible_prop): Support invisible properties on strings
9702 that are being bidi-reordered.
9703 (set_iterator_to_next): Support bidi reordering of C strings and
9704 Lisp strings.
9705 (next_element_from_string): Support bidi reordering of Lisp
9706 strings.
9707 (handle_stop_backwards): Support Lisp strings as well.
9708 (display_string): Support display of R2L glyph rows.
9709 Use IT_STRING_CHARPOS when displaying from a Lisp string.
9710 (init_iterator): Don't initialize it->bidi_p for strings
9711 here.
9712 (reseat_to_string): Initialize it->bidi_p for strings here.
9713 (next_element_from_string, next_element_from_c_string)
9714 (next_element_from_buffer): Add xassert's for correspondence
9715 between IT's object being iterated and it->bidi_it.string
9716 structure.
9717 (face_before_or_after_it_pos): Support bidi iteration.
9718 (next_element_from_c_string): Handle the case of the first string
9719 character that is not the first one in the visual order.
9720 (get_visually_first_element): New function, refactored from common
9721 parts of next_element_from_buffer, next_element_from_string, and
9722 next_element_from_c_string.
9723 (tool_bar_lines_needed, redisplay_tool_bar)
9724 (display_menu_bar): Force left-to-right direction. Add a FIXME
9725 comment for making that be controlled by a user option.
9726 (push_it, pop_it): Save and restore the state of the
9727 bidi iterator. Save and restore the bidi_p flag.
9728 (pop_it): Iterate out of display property for string iteration as
9729 well.
9730 (iterate_out_of_display_property): Support iteration over strings.
9731 (handle_single_display_spec): Set up it->bidi_it for iteration
9732 over a display string, and call bidi_init_it.
9733 (handle_single_display_spec, next_overlay_string)
9734 (get_overlay_strings_1, push_display_prop): Set up the bidi
9735 iterator for displaying display or overlay strings.
9736 (forward_to_next_line_start): Don't use the shortcut if
9737 bidi-iterating.
9738 (back_to_previous_visible_line_start): If handle_display_prop
9739 pushed the iterator stack, restore the internal state of the bidi
9740 iterator by calling bidi_pop_it same number of times.
9741 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
9742 and we are bidi-iterating, don't decrement the iterator position;
9743 instead, set the first_elt flag in the bidi iterator, to produce
9744 the same effect.
9745 (reseat_1): Remove redundant setting of string_from_display_prop_p.
9746 (push_display_prop): xassert that we are iterating a buffer.
9747 (push_it, pop_it): Save and restore paragraph_embedding member.
9748 (handle_single_display_spec, next_overlay_string)
9749 (get_overlay_strings_1, reseat_1, reseat_to_string)
9750 (push_display_prop): Set up the `unibyte' member of bidi_it.string
9751 correctly. Don't assume unibyte strings are not bidi-reordered.
9752 (compute_display_string_pos)
9753 (compute_display_string_end): Fix handling the case of C string.
9754 (push_it, pop_it): Save and restore from_disp_prop_p.
9755 (handle_single_display_spec, push_display_prop): Set the
9756 from_disp_prop_p flag.
9757 (get_overlay_strings_1): Reset the from_disp_prop_p flag.
9758 (pop_it): Call iterate_out_of_display_property only if we are
9759 popping after iteration over a string that came from a display
9760 property. Fix a typo in popping stretch info. Add an assertion
9761 for verifying that the iterator position is in sync with the bidi
9762 iterator.
9763 (handle_single_display_spec, get_overlay_strings_1)
9764 (push_display_prop): Fix initialization of paragraph direction for
9765 string when that of the parent object is not yet determined.
9766 (reseat_1): Call bidi_init_it to resync the bidi
9767 iterator with IT's position. (Bug#7616)
9768 (find_row_edges): If ROW->start.pos gives position
9769 smaller than min_pos, use it as ROW->minpos. (Bug#7616)
9770 (handle_stop, back_to_previous_visible_line_start, reseat_1):
9771 Reset the from_disp_prop_p flag.
9772 (SAVE_IT, RESTORE_IT): New macros.
9773 (pos_visible_p, face_before_or_after_it_pos)
9774 (back_to_previous_visible_line_start)
9775 (move_it_in_display_line_to, move_it_in_display_line)
9776 (move_it_to, move_it_vertically_backward, move_it_by_lines)
9777 (try_scrolling, redisplay_window, display_line): Use them when
9778 saving a temporary copy of the iterator and restoring it back.
9779 (back_to_previous_visible_line_start, reseat_1)
9780 (init_iterator): Empty the bidi cache "stack".
9781 (move_it_in_display_line_to): If iterator ended up at
9782 EOL, but we never saw any buffer positions smaller than
9783 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
9784 motion in bidi-reordered lines.
9785 (move_it_in_display_line_to): Record prev_method and prev_pos
9786 immediately before the call to set_iterator_to_next. Fixes cursor
9787 motion in bidi-reordered lines with stretch glyphs and strings
9788 displayed in margins. (Bug#8133) (Bug#8867)
9789 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
9790 TO_CHARPOS.
9791 (pos_visible_p): Support positions in bidi-reordered lines.
9792 Save and restore bidi cache.
9794 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.
9795 (bidi_paragraph_info): Delete unused struct.
9796 (bidi_cache_idx, bidi_cache_last_idx): Declare EMACS_INT.
9797 (bidi_cache_start): New variable.
9798 (bidi_cache_reset): Reset bidi_cache_idx to bidi_cache_start, not
9799 to zero.
9800 (bidi_cache_fetch_state, bidi_cache_search)
9801 (bidi_cache_find_level_change, bidi_cache_iterator_state)
9802 (bidi_cache_find, bidi_peek_at_next_level)
9803 (bidi_level_of_next_char, bidi_find_other_level_edge)

10216 Random fixes. E.g., (random) never returned negative values.
10217 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
10218 subseconds part to the entropy, as that's a bit more random.
10219 Prefer signed to unsigned, since the signedness doesn't matter and
10220 in general we prefer signed. When given a limit, use a
10221 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
10222 latter isn't right if USE_2_TAGS_FOR_INTS.
10223 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
10224 not 0..VALMASK. Don't discard "excess" bits that random () returns.

10234 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
10236 * fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.

10248 error be more correct.
10250 * fns.c (Frequire): Remove the mention of the .gz files, since

10262 (syms_of_gnutls): Remove duplicate DEFSYM for
10263 Qgnutls_bootprop_verify_hostname_error, an error for
10264 Qgnutls_bootprop_verify_error (which is no longer used).
10266 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
10267 unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca. All callers changed.

10369 * eval.c (struct backtrace): Simplify and port the data structure.
10370 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
10371 signed bit field, as this assumption is not portable and it makes
10372 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
10373 "char debug_on_exit : 1" as this is not portable either; instead,
10374 use the portable "unsigned int debug_on_exit : 1". Remove unused
10375 member evalargs. Remove obsolete comments about cc bombing out.
10377 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>
10379 * xsettings.c: Include glib-object.h, gio/gio.h if HAVE_GSETTINGS.

10422 * window.c (Fwindow_vchild): Rename to Fwindow_top_child.
10423 (Fwindow_hchild): Rename to Fwindow_left_child.
10424 (Fwindow_next): Rename to Fwindow_next_sibling.

10448 frames size_hint to set minimum and natural (Bug#8919).
10449 (XSetWMSizeHints, XSetWMNormalHints): Override these functions
10450 and use min_width/height from frames size_hint to set
10451 min_width/height (Bug#8919).
10453 * gtkutil.c (xg_create_frame_widgets): Pass f to emacs_fixed_new.
10454 (x_wm_set_size_hint): Remove call to emacs_fixed_set_min_size.

10563 to improve quality of diagnostics for out-of-range radices.
10564 Calculate buffer size correctly for out-of-range radices.
10565 (read1): Check for integer overflow in radices, and in
10566 read-circle numbers.
10567 (read_escape): Avoid int overflow.
10568 (Fload, openp, read_buffer_size, read1)
10569 (substitute_object_recurse, read_vector, read_list, map_obarray):

10592 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
10593 The following patches are for when GLYPH_DEBUG && !XASSERT.
10594 * dispextern.h (trace_redisplay_p, dump_glyph_string):
10595 * dispnew.c (flush_stdout):
10596 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
10597 Mark as externally visible.
10598 * dispnew.c (check_window_matrix_pointers): Now static.
10599 * dispnew.c (window_to_frame_vpos):

10608 Now static.
10609 (debug_method_add): Use va_list and vsprintf rather than relying
10610 on undefined behavior with wrong number of arguments.
10611 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
10612 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
10613 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
10614 since we're not interested in debugging glyphs with old libraries.
10615 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
10616 GCC 4.6.0's static checking.
10618 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>

10652 Use ptrdiff_t, not int, for sizes.
10653 (overlays_at, overlays_in): Check for size-calculation overflow.
10655 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
10657 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
10658 (x_session_initialize): Do not assume string length fits in int.
10660 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
10661 This is unlikely, but can occur if DPI is outlandish.
10663 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
10664 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
10666 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
10667 * xrdb.c (magic_file_p, search_magic_path):
10668 Omit last arg SUFFIX; it was always 0. All callers changed.
10669 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
10671 * xfont.c (xfont_match): Avoid need for strlen.
10673 * xfns.c: Don't assume strlen fits in int.
10674 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
10676 * xdisp.c (message_log_check_duplicate): Return intmax_t,
10677 not unsigned long, as we prefer signed integers. All callers changed.
10678 Detect integer overflow in repeat count.
10679 (message_dolog): Don't assume print length fits in 39 bytes.
10680 (display_mode_element): Don't assume strlen fits in int.
10682 * termcap.c: Don't assume sizes fit in int and never overflow.
10683 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
10684 (gobble_line): Check for size-calculation overflow.
10686 * minibuf.c (Fread_buffer):
10687 * lread.c (intern, intern_c_string):
10688 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
10689 Don't assume string length fits in int.
10691 * keyboard.c (parse_tool_bar_item):
10692 * gtkutil.c (style_changed_cb): Avoid need for strlen.
10694 * font.c: Don't assume string length fits in int.
10695 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
10696 Use ptrdiff_t, not int.
10697 (font_intern_prop): Don't assume string length fits in int.
10698 Don't assume integer property fits in fixnum.
10699 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
10701 * filelock.c: Fix some buffer overrun and integer overflow issues.
10702 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
10703 Reformulate so as not to need the command string.
10704 Invoke gzip -cd rather than gunzip, as it's more portable.
10705 (lock_info_type, lock_file_1, lock_file):
10706 Don't assume pid_t and time_t fit in unsigned long.
10707 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
10708 (current_lock_owner): Prefer signed type for sizes.
10709 Use memcpy, not strncpy, where memcpy is what is really wanted.
10710 Don't assume (via atoi) that time_t and pid_t fit in int.
10711 Check for time_t and/or pid_t out of range, e.g., via a network share.
10712 Don't alloca where an auto var works fine.
10714 * fileio.c: Fix some integer overflow issues.
10715 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
10716 Don't assume string length fits in int.
10717 (directory_file_name): Don't assume string length fits in long.
10718 (make_temp_name): Don't assume pid fits in int, or that its print
10719 length is less than 20.
10721 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
10723 * coding.c (make_subsidiaries): Don't assume string length fits in int.
10725 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
10727 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
10728 We prefer signed integers, even for size calculations.
10730 * emacs.c: Don't assume string length fits in 'int'.
10731 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
10732 (main): Don't invoke strlen when not needed.
10734 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
10735 (XD_DEBUG_MESSAGE): Don't waste a byte.
10737 * callproc.c (getenv_internal_1, getenv_internal)
10738 (Fgetenv_internal):
10739 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
10741 * lread.c (invalid_syntax): Omit length argument.
10742 All uses changed. This doesn't fix a bug, but it simplifies the
10743 code away from its former Hollerith-constant appearance, and it's
10744 one less 'int' to worry about when looking at integer-overflow issues.
10745 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
10747 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
10748 This didn't break anything, but it didn't help either.
10749 It's confusing to put a bogus integer in a place where the actual
10750 value does not matter.
10751 (LIST_END_P): Remove unused macro and its bogus comment.
10752 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
10754 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
10755 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
10756 implementation.
10757 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
10758 We prefer signed types, and the value cannot exceed the EMACS_INT
10759 range anyway (because otherwise the length would not be representable).
10760 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
10761 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
10762 This avoids a GCC warning when WIDE_EMACS_INT.
10764 * indent.c (sane_tab_width): New function.
10765 (current_column, scan_for_column, Findent_to, position_indentation)
10766 (compute_motion): Use it. This is just for clarity.
10767 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
10769 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
10771 * lisp.h (lint_assume): New macro.
10772 * composite.c (composition_gstring_put_cache):
10773 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
10775 * editfns.c, insdel.c:
10776 Omit unnecessary forward decls, to simplify future changes.
10778 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
10780 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
10782 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
10783 Use much-faster test for byte-length change.
10784 Don't assume string byte-length fits in 'int'.
10785 Check that character arg fits in 'int'.
10786 (mapcar1): Declare byte as byte, for clarity.
10788 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
10790 * fns.c (concat): Catch string overflow earlier.
10791 Do not rely on integer wraparound.
10793 * dispextern.h (struct it.overlay_strings_charpos)
10794 (struct it.selective): Now EMACS_INT, not int.
10795 * xdisp.c (forward_to_next_line_start)
10796 (back_to_previous_visible_line_start)
10797 (reseat_at_next_visible_line_start, next_element_from_buffer):
10798 Don't arbitrarily truncate the value of 'selective' to int.
10800 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
10802 * composite.c: Don't truncate sizes to 'int'.
10803 (composition_gstring_p, composition_reseat_it)
10804 (composition_adjust_point): Use EMACS_INT, not int.
10805 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
10806 not EMACS_UINT, for indexes.
10808 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
10810 * buffer.c: Include <verify.h>.
10811 (struct sortvec.priority, struct sortstr.priority):
10812 Now EMACS_INT, not int.
10813 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
10814 (struct sortstr.size, record_overlay_string)
10815 (struct sortstrlist.size, struct sortlist.used):
10816 Don't truncate size to int.
10817 (record_overlay_string): Check for size-calculation overflow.
10818 (init_buffer_once): Check at compile-time, not run-time.
10820 2011-06-22 Jim Meyering <meyering@redhat.com>
10822 Don't leak an XBM-image-sized buffer
10823 * image.c (xbm_load): Free the image buffer after using it.
10825 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
10827 Port to Sun C.
10828 * composite.c (find_automatic_composition): Omit needless 'return 0;'
10829 that Sun C diagnosed.
10830 * fns.c (secure_hash): Fix pointer signedness issue.
10831 * intervals.c (static_offset_intervals): New function.
10832 (offset_intervals): Use it.
10834 2011-06-21 Leo Liu <sdl.web@gmail.com>
10836 * deps.mk (fns.o):
10837 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
10838 sha512.h.
10840 * fns.c (secure_hash): Rename from crypto_hash_function and change
10841 the first arg to accept symbols.
10842 (Fsecure_hash): New primitive.
10843 (syms_of_fns): New symbols.
10845 2011-06-20 Deniz Dogan <deniz@dogan.se>
10847 * process.c (Fset_process_buffer): Clarify return value in
10848 docstring.
10850 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
10852 * dispnew.c (add_window_display_history): Use BVAR.
10854 * xdisp.c (debug_method_add): Use BVAR.
10855 (check_window_end, dump_glyph_matrix, dump_glyph)
10856 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
10858 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
10859 Likewise.
10861 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
10862 check till after the cache is created in init_frame_faces.
10864 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
10866 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
10868 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
10870 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
10871 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
10872 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
10874 Improve buffer-overflow checking (Bug#8873).
10875 * fileio.c (Finsert_file_contents):
10876 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
10877 Remove the old (too-loose) buffer overflow checks.
10878 They weren't needed, since make_gap checks for buffer overflow.
10879 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
10880 The old code merely checked for Emacs fixnum overflow, and relied
10881 on undefined (wraparound) behavior. The new code avoids undefined
10882 behavior, and also checks for ptrdiff_t and/or size_t overflow.
10884 * editfns.c (Finsert_char): Don't dump core with very negative counts.
10885 Tune. Don't use wider integers than needed. Don't use alloca.
10886 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
10888 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
10890 * insdel.c, lisp.h (buffer_overflow): New function.
10891 (insert_from_buffer_1, replace_range, replace_range_2):
10892 * insdel.c (make_gap_larger):
10893 * editfns.c (Finsert_char):
10894 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
10896 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
10898 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
10900 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
10902 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
10903 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
10905 * fileio.c: Don't assume EMACS_INT fits in off_t.
10906 (emacs_lseek): New static function.
10907 (Finsert_file_contents, Fwrite_region): Use it.
10908 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
10910 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
10912 * fns.c: Don't overflow int when computing a list length.
10913 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
10914 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
10915 truncation on 64-bit hosts. Check for QUIT every
10916 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
10917 faster and is responsive enough.
10918 (Flength): Report an error instead of overflowing an integer.
10919 (Fsafe_length): Return a float if the value is not representable
10920 as a fixnum. This shouldn't happen except in contrived situations.
10921 (Fnthcdr, Fsort): Don't assume list length fits in int.
10922 (Fcopy_sequence): Don't assume vector length fits in int.
10924 * alloc.c: Check that resized vectors' lengths fit in fixnums.
10925 (header_size, word_size): New constants.
10926 (allocate_vectorlike): Don't check size overflow here.
10927 (allocate_vector): Check it here instead, since this is the only
10928 caller of allocate_vectorlike that could cause overflow.
10929 Check that the new vector's length is representable as a fixnum.
10931 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
10932 The previous code was bogus. For example, next_almost_prime (32)
10933 returned 39, which is undesirable as it is a multiple of 3; and
10934 next_almost_prime (24) returned 25, which is a multiple of 5 so
10935 why was the code bothering to check for multiples of 7?
10937 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
10939 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
10941 Variadic C functions now count arguments with ptrdiff_t.
10942 This partly undoes my 2011-03-30 change, which replaced int with size_t.
10943 Back then I didn't know that the Emacs coding style prefers signed int.
10944 Also, in the meantime I found a few more instances where arguments
10945 were being counted with int, which may truncate counts on 64-bit
10946 machines, or EMACS_INT, which may be unnecessarily wide.
10947 * lisp.h (struct Lisp_Subr.function.aMANY)
10948 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
10949 Arg counts are now ptrdiff_t, not size_t.
10950 All variadic functions and their callers changed accordingly.
10951 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
10952 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
10953 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
10954 * callint.c (Fcall_interactively): Check arg count for overflow,
10955 to avoid potential buffer overrun. Use signed char, not 'int',
10956 for 'varies' array, so that we needn't bother to check its size
10957 calculation for overflow.
10958 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
10959 * eval.c (apply_lambda):
10960 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
10961 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
10962 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
10964 * callint.c (Fcall_interactively): Don't use index var as event count.
10966 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
10967 * mem-limits.h (SIZE): Remove; no longer used.
10969 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
10971 Remove unnecessary casts.
10972 * xterm.c (x_term_init):
10973 * xfns.c (x_set_border_pixel):
10974 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
10975 These aren't needed now that we assume ANSI C.
10977 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
10978 It's more likely to cause problems (due to unsigned overflow)
10979 than to cure them.
10981 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
10983 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
10985 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
10987 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
10989 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
10991 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
10993 GLYPH_CODE_FACE returns EMACS_INT, not int.
10994 * dispextern.h (merge_faces):
10995 * xfaces.c (merge_faces):
10996 * xdisp.c (get_next_display_element, next_element_from_display_vector):
10997 Don't assume EMACS_INT fits in int.
10999 * character.h (CHAR_VALID_P): Remove unused parameter.
11000 * fontset.c, lisp.h, xdisp.c: All uses changed.
11002 * editfns.c (Ftranslate_region_internal): Omit redundant test.
11004 * fns.c (concat): Minor tuning based on overflow analysis.
11005 This doesn't fix any bugs. Use int to hold character, instead
11006 of constantly refetching from Emacs object. Use XFASTINT, not
11007 XINT, for value known to be a character. Don't bother comparing
11008 a single byte to 0400, as it's always less.
11010 * floatfns.c (Fexpt):
11011 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
11013 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
11014 for characters.
11016 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
11018 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
11019 Without this fix, on a 64-bit host (aset S 0 4294967386) would
11020 incorrectly succeed when S was a string, because 4294967386 was
11021 truncated before it was used.
11023 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
11024 Otherwise, an out-of-range integer could cause undefined behavior
11025 on a 64-bit host.
11027 * composite.c: Use int, not EMACS_INT, for characters.
11028 (fill_gstring_body, composition_compute_stop_pos): Use int, not
11029 EMACS_INT, for values that are known to be in character range.
11030 This doesn't fix any bugs but is the usual style inside Emacs and
11031 may generate better code on 32-bit machines.
11033 Make sure a 64-bit char is never passed to ENCODE_CHAR.
11034 This is for reasons similar to the recent CHAR_STRING fix.
11035 * charset.c (Fencode_char): Check that character arg is actually
11036 a character. Pass an int to ENCODE_CHAR.
11037 * charset.h (ENCODE_CHAR): Verify that the character argument is no
11038 wider than 'int', as a compile-time check to prevent future regressions
11039 in this area.
11041 * character.c (char_string): Remove unnecessary casts.
11043 Make sure a 64-bit char is never passed to CHAR_STRING.
11044 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
11045 by silently ignoring the top 32 bits, allowing some values
11046 that were far too large to be valid characters.
11047 * character.h: Include <verify.h>.
11048 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
11049 arguments are no wider than unsigned, as a compile-time check
11050 to prevent future regressions in this area.
11051 * data.c (Faset):
11052 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
11053 (Fsubst_char_in_region):
11054 * fns.c (concat):
11055 * xdisp.c (decode_mode_spec_coding):
11056 Adjust to CHAR_STRING's new requirement.
11057 * editfns.c (Finsert_char, Fsubst_char_in_region):
11058 * fns.c (concat): Check that character args are actually
11059 characters. Without this test, these functions did the wrong
11060 thing with wildly out-of-range values on 64-bit hosts.
11062 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
11063 These casts should not be needed on 32-bit hosts, either.
11064 * keyboard.c (read_char):
11065 * lread.c (Fload): Remove casts to unsigned.
11067 * lisp.h (UNSIGNED_CMP): New macro.
11068 This fixes comparison bugs on 64-bit hosts.
11069 (ASCII_CHAR_P): Use it.
11070 * casefiddle.c (casify_object):
11071 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
11072 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
11073 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
11074 * dispextern.h (FACE_FROM_ID):
11075 * keyboard.c (read_char): Use UNSIGNED_CMP.
11077 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
11078 not to EMACS_INT, to avoid GCC warning.
11080 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
11082 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
11083 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
11084 isn't needed on 32-bit machines.
11086 * buffer.c (Fgenerate_new_buffer_name):
11087 Use EMACS_INT for count, not int.
11088 (advance_to_char_boundary): Return EMACS_INT, not int.
11090 * data.c (Qcompiled_function): Now static.
11092 * window.c (window_body_lines): Now static.
11094 * image.c (gif_load): Rename local to avoid shadowing.
11096 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
11097 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
11098 * alloc.c (make_save_value): Integer argument is now of type
11099 ptrdiff_t, not int.
11100 (mark_object): Use ptrdiff_t, not int.
11101 * lisp.h (pD): New macro.
11102 * print.c (print_object): Use it.
11104 * alloc.c: Use EMACS_INT, not int, to count objects.
11105 (total_conses, total_markers, total_symbols, total_vector_size)
11106 (total_free_conses, total_free_markers, total_free_symbols)

11115 These were 'int' variables that could overflow on 64-bit hosts;
11116 they were never used, so remove them instead of repairing them.

11118 (inhibit_garbage_collection): Set gc_cons_threshold to max value.

11132 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
11133 The definition here is exact; the one in lisp.h was approximate.
11134 (allocate_string_data): Check for string overflow. This catches
11135 some instances we weren't catching before. Also, it catches
11136 size_t overflow on (unusual) hosts where SIZE_MAX <= min
11137 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
11138 and ptrdiff_t and EMACS_INT are both 64 bits.
11140 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
11141 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.

11591 XUINT -> XFASTINT, since the integer must be nonnegative.
11592 (Fsingle_key_description, preferred_sequence_p): XUINT -> XINT,
11593 since it makes no difference and we prefer signed.

11646 * alloc.c (memory_full) [SYSTEM_MALLOC]: Port to MacOS (Bug#8800).
11647 Do not assume that spare memory exists; that assumption is valid
11648 only if SYSTEM_MALLOC.
11649 (LARGE_REQUEST): New macro, so that the issue of large requests
11650 is separated from the issue of spare memory.

11710 display string.
11711 (bidi_paragraph_init, bidi_resolve_explicit_1)
11712 (bidi_level_of_next_char): Call bidi_fetch_char and

11717 definitions.
11718 (bidi_explicit_dir_char): Lookup character type in bidi_type_table,
11719 instead of using explicit *_CHAR codes.
11720 (bidi_resolve_explicit, bidi_resolve_weak):
11721 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
11722 bidirectional text is supported only in multibyte buffers.
11723 (bidi_init_it): Accept additional argument FRAME_WINDOW_P and use
11724 it to initialize the frame_window_p member of struct bidi_it.

11729 (bidi_level_of_next_char): Don't try to lookup the cache for the
11730 next/previous character if nothing is cached there yet, or if we
11731 were just reseat()'ed to a new position.
11733 * xdisp.c (set_cursor_from_row): Set start and stop points
11734 according to the row's direction when priming the loop that looks
11735 for the glyph on which to display cursor.
11736 (single_display_spec_intangible_p): Function deleted.
11737 (display_prop_intangible_p): Reimplement to call
11738 handle_display_spec instead of single_display_spec_intangible_p.
11739 Accept 3 additional arguments needed by handle_display_spec.
11740 This fixes incorrect cursor motion across display property with complex
11741 values: lists, `(when COND...)' forms, etc.

11743 lists with the argument STRING its top-level element.
11744 (display_prop_string_p): Fix the condition for processing a
11745 property that is a list to be consistent with handle_display_spec.

11747 last portion of handle_display_prop.
11748 (compute_display_string_pos): Accept additional argument
11749 FRAME_WINDOW_P. Call handle_display_spec to determine whether the
11750 value of a `display' property is a "replacing spec".
11751 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
11752 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from
11753 the display property, but just return a value indicating whether
11754 the display property will replace the characters it covers.
11755 (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
11756 frame_window_p members of struct bidi_it.
11757 (compute_display_string_pos, compute_display_string_end):

11763 * keyboard.c (adjust_point_for_property): Adjust the call to
11764 display_prop_intangible_p to its new signature.
11766 * dispextern.h (struct bidi_it): New member frame_window_p.

11780 All callers changed. (Bug#8762)
11782 * gnutls.c: Use Emacs's memory allocators.
11783 Without this change, the gnutls library would invoke malloc etc.
11784 directly, which causes problems on non-SYNC_INPUT hosts, and which
11785 runs afoul of improving memory_full behavior. (Bug#8761)
11786 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
11787 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
11788 xfree instead of the default malloc, realloc, free.
11789 (Fgnutls_boot): No need to check for memory allocation failure,
11790 since xmalloc does that for us.
11792 Remove arbitrary limit of 2**31 entries in hash tables. (Bug#8771)
11793 * category.c (hash_get_category_set):
11794 * ccl.c (ccl_driver):

11810 * lisp.h (struct Lisp_Hash_Table):
11811 * minibuf.c (Ftry_completion, Fall_completions, Ftest_completion):
11812 * print.c (print): Use 'EMACS_UINT' and 'EMACS_INT'
11813 for hashes and hash indexes, instead of 'unsigned' and 'int'.
11814 * alloc.c (allocate_vectorlike):
11815 Check for overflow in vector size calculations.
11816 * ccl.c (ccl_driver):
11817 Check for overflow when converting EMACS_INT to int.
11818 * fns.c, image.c: Remove unnecessary static decls that would otherwise
11819 need to be updated by these changes.
11820 * fns.c (make_hash_table, maybe_resize_hash_table):
11821 Check for integer overflow with large hash tables.
11822 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
11823 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
11824 (SXHASH_REDUCE): New macro.
11825 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
11826 Use it instead of discarding useful hash info with large hash values.
11827 (sxhash_float): New function.
11828 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
11829 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
11830 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
11831 Rewrite to use FIXNUM_BITS, as this simplifies things.
11832 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
11833 Adjust signatures to match updated version of code.
11834 (consing_since_gc): Now EMACS_INT, since a single hash table can
11835 use more than INT_MAX bytes.

11884 Make it possible to run ./temacs.
11886 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
11887 syms_of_callproc does the same thing. Remove test for
11888 "initialized", do it in the caller.
11889 * emacs.c (main): Avoid calling set_initial_environment when dumping.
11891 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>

11948 * fns.c (to_uchar): Define.
11949 (crypto_hash_function): Use it to convert some newly-signed

11956 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
11958 Integer overflow fixes.
11960 * dbusbind.c: Serial number integer overflow fixes.
11961 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
11962 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
11963 to hold a serial number that is too large for a fixnum.
11964 (Fdbus_method_return_internal, Fdbus_method_error_internal):
11965 Check for serial numbers out of range. Decode any serial number
11966 that was so large that it became a float. (Bug#8722)
11968 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
11969 (Fdbus_call_method, Fdbus_call_method_asynchronously):
11970 Use XFASTINT rather than XUINT when numbers are nonnegative.
11971 (xd_append_arg, Fdbus_method_return_internal):
11972 (Fdbus_method_error_internal): Likewise. Also, for unsigned
11973 arguments, check that Lisp number is nonnegative, rather than
11974 silently wrapping negative numbers around. (Bug#8722)
11975 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
11976 (Bug#8722)
11978 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
11980 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
11982 ccl: Add integer overflow checks.
11983 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
11984 (IN_INT_RANGE): New macros.
11985 (ccl_driver): Use them to check for integer overflow when
11986 decoding a CCL program. Many of the new checks are whether XINT (x)
11987 fits in int; it doesn't always, on 64-bit hosts. The new version
11988 doesn't catch all possible integer overflows, but it's an
11989 improvement. (Bug#8719)
11991 * alloc.c (make_event_array): Use XINT, not XUINT.
11992 There's no need for unsigned here.
11994 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
11995 This follows up to the 2011-05-06 change that substituted uintptr_t
11996 for EMACS_INT. This case wasn't caught back then.
11998 Rework Fformat to avoid integer overflow issues.
11999 * editfns.c: Include <float.h> unconditionally, as it's everywhere
12000 now (part of C89). Include <verify.h>.
12001 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
12002 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
12003 (Fformat): Avoid the prepass trying to compute sizes; it was only
12004 approximate and thus did not catch overflow reliably. Instead, walk
12005 through the format just once, formatting and computing sizes as we go,
12006 checking for integer overflow at every step, and allocating a larger
12007 buffer as needed. Keep track separately whether the format is
12008 multibyte. Keep only the most-recently calculated precision, rather
12009 than them all. Record whether each argument has been converted to
12010 string. Use EMACS_INT, not int, for byte and char and arg counts.
12011 Support field widths and precisions larger than INT_MAX. Avoid
12012 sprintf's undefined behavior with conversion specifications such as %#d
12013 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
12014 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
12015 formatting out-of-range floating point numbers with int
12016 formats. (Bug#8668)
12018 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
12020 * data.c: Avoid integer truncation in expressions involving floats.
12021 * data.c: Include <intprops.h>.
12022 (arith_driver): When there's an integer overflow in an expression
12023 involving floating point, convert the integers to floating point
12024 so that the resulting value does not suffer from catastrophic
12025 integer truncation. For example, on a 64-bit host (* 4
12026 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
12027 Do not rely on undefined behavior after integer overflow.
12029 merge count_size_as_multibyte, parse_str_to_multibyte
12030 * character.c, character.h (count_size_as_multibyte):
12031 Rename from parse_str_to_multibyte; all uses changed.
12032 Check for integer overflow.
12033 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
12034 since it's now a duplicate of the other. This is more of
12035 a character than a buffer op, so better that it's in character.c.
12036 * fns.c, print.c: Adjust to above changes.
12038 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
12040 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
12042 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
12044 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
12045 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
12046 (x_clipboard_manager_save): Now static.
12047 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
12049 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
12050 (crypto_hash_function): Now static.
12051 Fix pointer signedness problems. Avoid unnecessary initializations.
12053 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
12055 * termhooks.h (Vselection_alist): Make it terminal-local.
12057 * terminal.c (create_terminal): Initialize it.
12059 * xselect.c: Support for clipboard managers.
12060 (Vselection_alist): Move to termhooks.h as terminal-local var.
12061 (LOCAL_SELECTION): New macro.
12062 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
12063 (symbol_to_x_atom): Remove gratuitous arg.
12064 (x_handle_selection_request, lisp_data_to_selection_data)
12065 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
12066 (x_own_selection, x_get_local_selection, x_convert_selection):
12067 New arg, specifying work frame. Use terminal-local Vselection_alist.
12068 (some_frame_on_display): Delete unused function.
12069 (Fx_own_selection_internal, Fx_get_selection_internal)
12070 (Fx_disown_selection_internal, Fx_selection_owner_p)
12071 (Fx_selection_exists_p): New optional frame arg.
12072 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
12073 (x_handle_selection_clear): Don't treat other terminals with the
12074 same keyboard specially. Use the terminal-local Vselection_alist.
12075 (x_clear_frame_selections): Use Frun_hook_with_args.
12077 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
12079 * xterm.h: Add support for those atoms.
12081 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
12083 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
12084 (converted_selections, conversion_fail_tag): New global variables.
12085 (x_selection_request_lisp_error): Free the above.
12086 (x_get_local_selection): Remove unnecessary code.
12087 (x_reply_selection_request): Args changed; handle arbitrary array
12088 of converted selections stored in converted_selections.
12089 Separate the XChangeProperty and SelectionNotify steps.
12090 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
12091 (x_convert_selection): New function.
12092 (x_handle_selection_event): Simplify.
12093 (x_get_foreign_selection): Don't ignore incoming requests while
12094 waiting for an answer; this will fail when we implement
12095 SAVE_TARGETS, and seems unnecessary anyway.
12096 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
12097 (Vx_sent_selection_functions): Doc fix.
12099 2011-05-26 Leo Liu <sdl.web@gmail.com>
12101 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
12103 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
12105 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
12107 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
12108 for fringe update if it has periodic bitmap.
12109 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
12110 and fringe_bitmap_periodic_p.
12112 * fringe.c (get_fringe_bitmap_data): New function.
12113 (draw_fringe_bitmap_1, update_window_fringes): Use it.
12114 (update_window_fringes): Record periodicity of fringe bitmap in glyph
12115 row. Mark glyph row for fringe update if periodicity changed.
12117 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
12118 for fringe update unless it has periodic bitmap.
12120 2011-05-25 Kenichi Handa <handa@m17n.org>
12122 * xdisp.c (get_next_display_element): Set correct it->face_id for
12123 a static composition.
12125 2011-05-24 Leo Liu <sdl.web@gmail.com>
12127 * deps.mk (fns.o):
12128 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
12130 * fns.c (crypto_hash_function, Fsha1): New function.
12131 (Fmd5): Use crypto_hash_function.
12132 (syms_of_fns): Add Ssha1.
12134 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
12136 * gnutls.c: Remove unused macros.
12137 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
12138 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
12139 Remove macros that are defined and never used.
12140 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
12142 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
12144 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
12145 (Fx_get_selection_internal): Minor cleanup.
12146 (Fx_own_selection_internal): Rename arguments for consistency with
12147 select.el.
12149 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
12151 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
12153 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
12155 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
12157 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
12159 * dispnew.c (scrolling_window): Don't exclude the case that the
12160 last enabled row in the desired matrix touches the bottom boundary.
12162 2011-05-21 Glenn Morris <rgm@gnu.org>
12164 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
12165 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
12166 and add some more files.
12168 2011-05-20 Eli Zaretskii <eliz@gnu.org>
12170 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
12171 report_file_error introduced by the change from 2011-05-07.
12173 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
12175 * systime.h (Time): Define only if emacs is defined.
12176 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
12177 where the include path doesn't have X11/X.h by default. See
12178 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
12180 2011-05-20 Kenichi Handa <handa@m17n.org>
12182 * composite.c (find_automatic_composition): Fix previous change.
12184 2011-05-20 Glenn Morris <rgm@gnu.org>
12186 * lisp.mk: New file, split from Makefile.in.
12187 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
12188 (shortlisp): Remove.
12189 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
12191 2011-05-19 Glenn Morris <rgm@gnu.org>
12193 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
12194 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
12195 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
12196 (lisp): Set the order to that of loadup.el.
12197 (shortlisp): Make it a copy of $lisp.
12198 (SOME_MACHINE_LISP): Remove.
12199 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
12200 Use just $shortlisp, not $SOME_MACHINE_LISP too.
12202 2011-05-18 Kenichi Handa <handa@m17n.org>
12204 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
12205 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
12206 (find_automatic_composition): Mostly rewrite for efficiency.
12208 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
12210 * makefile.w32-in: Update dependencies.
12212 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
12214 * menu.c: Include limits.h (fixes the MS-Windows build broken by
12215 2011-06-18T18:49:19Z!cyd@stupidchicken.com).
12217 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
12219 Fix some integer overflow issues, such as string length overflow.
12221 * insdel.c (count_size_as_multibyte): Check for string overflow.
12223 * character.c (lisp_string_width): Check for string overflow.
12224 Use EMACS_INT, not int, for string indexes and lengths; in
12225 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
12226 the resulting string length overflows an EMACS_INT; instead,
12227 report a string overflow if no precision given. When checking for
12228 precision exhaustion, use a check that cannot possibly have
12229 integer overflow. (Bug#8675)
12230 * character.h (lisp_string_width): Adjust to new signature.
12232 * alloc.c (string_overflow): New function.
12233 (Fmake_string): Use it. This doesn't change behavior, but saves
12234 a few bytes and will simplify future changes.
12235 * character.c (string_escape_byte8): Likewise.
12236 * lisp.h (string_overflow): New decl.
12238 Fixups, following up to the user-interface timestamp change.
12239 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
12240 for UI timestamps, instead of unsigned long.
12241 * msdos.c (mouse_get_pos): Likewise.
12242 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
12243 * w32gui.h (Time): Define by including "systime.h" rather than by
12244 declaring it ourselves. (Bug#8664)
12246 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
12247 * image.c (clear_image_cache): Likewise.
12249 * term.c (term_mouse_position): Don't assume time_t wraparound.
12251 Be more systematic about user-interface timestamps.
12252 Before, the code sometimes used 'Time', sometimes 'unsigned long',
12253 and sometimes 'EMACS_UINT', to represent these timestamps.
12254 This change causes it to use 'Time' uniformly, as that's what X uses.
12255 This makes the code easier to follow, and makes it easier to catch
12256 integer overflow bugs such as Bug#8664.
12257 * frame.c (Fmouse_position, Fmouse_pixel_position):
12258 Use Time, not unsigned long, for user-interface timestamps.
12259 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
12260 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
12261 * keyboard.h (last_event_timestamp): Likewise.
12262 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
12263 * menu.h (xmenu_show): Likewise.
12264 * term.c (term_mouse_position): Likewise.
12265 * termhooks.h (struct input_event.timestamp): Likewise.
12266 (struct terminal.mouse_position_hook): Likewise.
12267 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
12268 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
12269 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
12270 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
12271 what it was before.
12272 * menu.h, termhooks.h: Include "systime.h", for Time.
12274 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
12275 Don't assume that the difference between two unsigned long values
12276 can fit into an integer. At this point, we know button_down_time
12277 <= event->timestamp, so the difference must be nonnegative, so
12278 there's no need to cast the result if double-click-time is
12279 nonnegative, as it should be; check that it's nonnegative, just in
12280 case. This bug is triggered when events are more than 2**31 ms
12281 apart (about 25 days). (Bug#8664)
12283 * xselect.c (last_event_timestamp): Remove duplicate decl.
12284 (x_own_selection): Remove needless cast to unsigned long.
12286 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
12287 that always fit in int. Use a sentinel instead of a counter, to
12288 avoid a temp and to allay GCC's concerns about possible int overflow.
12289 * frame.h (struct frame): Use int for menu_bar_items_used
12290 instead of EMACS_INT, since it always fits in int.
12292 * menu.c (grow_menu_items): Check for int overflow.
12294 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
12296 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
12297 Before, the code was not consistent. These values cannot exceed
12298 2**31 - 1 so there's no need to make them unsigned.
12299 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
12300 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
12301 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
12302 as modifiers.
12303 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
12305 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
12306 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
12307 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
12308 presumably because the widths might not match.
12310 * window.c (size_window): Avoid needless test at loop start.
12312 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
12314 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
12316 2011-05-12 Drew Adams <drew.adams@oracle.com>
12318 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
12320 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
12322 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
12323 `width' to `bar_area_x' and `bar_area_width', respectively.
12324 (x_scroll_run): Take account of fringe background extension.
12326 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
12327 Rename local vars `left' and `width' to `bar_area_x' and
12328 `bar_area_width', respectively.
12329 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
12330 background extension.
12332 2011-05-10 Jim Meyering <meyering@redhat.com>
12334 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
12336 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
12338 * image.c (Finit_image_library): Return t for built-in image types,
12339 like pbm and xbm. (Bug#8640)
12341 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
12343 * w32menu.c (set_frame_menubar): Fix submenu allocation.
12345 2011-05-07 Eli Zaretskii <eliz@gnu.org>
12347 * w32console.c (Fset_screen_color): Doc fix.
12348 (Fget_screen_color): New function.
12349 (syms_of_ntterm): Defsubr it.
12351 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
12352 unlink the temporary file if Fcall_process didn't create it in the
12353 first place.
12354 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
12355 child process will be redirected to a file specified with `:file'.
12356 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
12357 cue to call_process_cleanup not to close that handle.
12359 2011-05-07 Ben Key <bkey76@gmail.com>
12361 * makefile.w32-in: The bootstrap-temacs rule now makes use of
12362 one of two shell specific rules, either bootstrap-temacs-CMD or
12363 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
12364 to the previous implementation of the bootstrap-temacs rule.
12365 The bootstrap-temacs-CMD rule is similar to the previous
12366 implementation of the bootstrap-temacs rule except that it
12367 makes use of the ESC_CFLAGS variable instead of the CFLAGS
12368 variable.
12370 These changes, along with some changes to nt/configure.bat,
12371 nt/gmake.defs, and nt/nmake.defs, are required to extend my
12372 earlier fix to add support for --cflags and --ldflags options
12373 that include quotes so that it works whether make uses cmd or
12374 sh as the shell.
12376 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
12378 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
12379 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
12380 is a constant.
12381 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
12382 a string. Handle both cases.
12383 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
12384 (Fdbus_register_method): Use Qinvalid_function.
12386 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
12388 * makefile.w32-in: Update dependencies.
12389 (LISP_H): Add inttypes.h and stdin.h.
12390 (PROCESS_H): Add unistd.h.
12392 2011-05-06 Eli Zaretskii <eliz@gnu.org>
12394 * lread.c: Include limits.h (fixes the MS-Windows build broken by
12395 2011-05-06T07:13:19Z!eggert@cs.ucla.edu).
12397 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
12399 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
12401 * term.c (vfatal): Remove stray call to va_end.
12402 It's not needed and the C Standard doesn't allow it here anyway.
12404 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
12405 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
12407 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
12408 bytes.
12410 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
12412 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
12414 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
12416 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
12418 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
12420 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
12421 * charset.c (Fdefine_charset_internal): Don't initialize
12422 charset.code_space[15]. The value was garbage, on hosts with
12423 32-bit int (Bug#8600).
12425 * lread.c (read_integer): Be more consistent with string-to-number.
12426 Use string_to_number to do the actual conversion; this avoids
12427 rounding errors and fixes some other screwups. Without this fix,
12428 for example, #x1fffffffffffffff was misread as -2305843009213693952.
12429 (digit_to_number): Move earlier, for benefit of read_integer.
12430 Return -1 if the digit is out of range for the base, -2 if it is
12431 not a digit in any supported base. (Bug#8602)
12433 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
12435 * dispnew.c (scrolling_window): Return 1 if we scrolled,
12436 to match comment at start of function. This also removes a
12437 GCC warning about overflow in a 32+64-bit port.
12439 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
12441 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
12442 Reported by Stefan Monnier in
12443 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
12444 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
12445 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
12447 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
12448 (EMACS_UINTPTR): Likewise, with uintptr_t.
12450 * lisp.h: Prefer 64-bit EMACS_INT if available.
12451 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
12452 on 32-bit hosts that have 64-bit int, so that they can access
12453 large files.
12454 However, temporarily disable this change unless the temporary
12455 symbol WIDE_EMACS_INT is defined.
12457 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
12459 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
12460 This removes an assumption that EMACS_INT and long are the same
12461 width as pointers. The assumption is true for Emacs porting targets
12462 now, but we want to make other targets possible.
12463 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
12464 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
12465 In the rest of the code, change types of integers that hold casted
12466 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
12467 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
12468 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
12469 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
12470 No need to cast type when ORing.
12471 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
12472 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
12473 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
12474 assume EMACS_INT is the same width as char *.
12475 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
12476 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
12477 Remove no-longer-needed casts.
12478 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
12479 (xg_tool_bar_help_callback, xg_make_tool_item):
12480 Use EMACS_INTPTR to hold an integer
12481 that will be cast to void *; this can avoid a GCC warning
12482 if EMACS_INT is not the same width as void *.
12483 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
12484 * xdisp.c (display_echo_area_1, resize_mini_window_1):
12485 (current_message_1, set_message_1):
12486 Use a local to convert to proper width without a cast.
12487 * xmenu.c (dialog_selection_callback): Likewise.
12489 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
12490 Also, don't assume VALBITS / RAND_BITS is less than 5,
12491 and don't rely on undefined behavior when shifting a 1 left into
12492 the sign bit.
12493 * lisp.h (get_random): Change signature to match.
12495 * lread.c (hash_string): Use size_t, not int, for hash computation.
12496 Normally we prefer signed values; but hashing is special, because
12497 it's better to use unsigned division on hash table sizes so that
12498 the remainder is nonnegative. Also, size_t is the natural width
12499 for hashing into memory. The previous code used 'int', which doesn't
12500 retain enough info to hash well into very large tables.
12501 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
12503 * dbusbind.c: Don't possibly lose pointer info when converting.
12504 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
12505 Use XPNTR rather than XHASH, so that the high-order bits of
12506 the pointer aren't lost when converting through void *.
12508 * eval.c (Fautoload): Don't double-shift a pointer.
12510 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
12512 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
12514 * gnutls.c (DEF_GNUTLS_FN):
12515 * image.c (DEF_IMGLIB_FN): Make function pointers static.
12517 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
12519 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
12520 marker. (Bug#8610)
12522 2011-05-05 Eli Zaretskii <eliz@gnu.org>
12524 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
12525 New version that can reserve upto 2GB of heap space.
12527 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
12529 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
12531 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
12533 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
12534 `gnutls_certificate_set_x509_key_file'.
12536 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
12538 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
12539 Update dependencies.
12541 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
12543 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
12544 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
12545 Remove unused parameter `fildes'.
12546 * process.c (read_process_output, send_process): Don't pass it.
12548 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
12550 Fix previous change: the library cache is defined in w32.c.
12551 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
12552 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
12554 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
12556 Implement dynamic loading of GnuTLS on Windows.
12558 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
12559 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
12560 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
12561 Declare.
12563 * gnutls.c (Qgnutls_dll): Define.
12564 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
12565 (gnutls_*): Declare function pointers.
12566 (init_gnutls_functions): New function to initialize function pointers.
12567 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
12568 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
12569 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
12570 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
12571 (emacs_gnutls_write, emacs_gnutls_read)
12572 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
12573 (Fgnutls_available_p): New function.
12574 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
12575 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.

12580 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
12581 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
12582 (w32_delayed_load): Move to w32.c.
12584 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
12586 * w32.c (QCloaded_from, Vlibrary_cache): Define.
12587 (w32_delayed_load): Move from image.c. When loading a library, record
12588 its filename in the :loaded-from property of the library id.
12589 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
12590 Initialize and staticpro them.
12591 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
12593 * process.c: Include lisp.h before w32.h, not after.
12594 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
12595 instead of gnutls_record_check_pending.
12597 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
12599 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
12601 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
12602 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
12603 as passed in.
12605 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
12607 * xterm.c (x_set_frame_alpha): Do not set property on anything
12608 else than FRAME_X_OUTER_WINDOW (Bug#8608).
12610 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
12612 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
12614 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
12616 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
12617 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

12622 (Qgnutls_bootprop_hostname, Qgnutls_bootprop_verify_flags)
12623 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
12624 (Qgnutls_bootprop_callbacks_verify): Make static.
12626 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
12628 * callproc.c: Indentation fixup.
12630 * sysdep.c (wait_for_termination_1): Make static.
12631 (wait_for_termination, interruptible_wait_for_termination):
12632 Move after wait_for_termination_1.
12634 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
12636 * sysdep.c (interruptible_wait_for_termination): New function
12637 which is like wait_for_termination, but allows keyboard
12638 interruptions.
12640 * callproc.c (Fcall_process): Add (:file "file") as an option for
12641 the STDOUT buffer.
12642 (Fcall_process_region): Ditto.
12644 2011-04-30 Eli Zaretskii <eliz@gnu.org>
12646 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
12647 rather than `XVECTOR (FOO)->size'.
12649 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
12650 inttypes.h, as a gnulib replacement is used if it not available in
12651 system headers.
12653 2011-04-21 Eli Zaretskii <eliz@gnu.org>
12655 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
12656 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
12657 of MOST_POSITIVE_FIXNUM. (Bug#8528)
12659 * coding.c (coding_alloc_by_realloc): Error out if destination
12660 will grow beyond MOST_POSITIVE_FIXNUM.
12661 (decode_coding_emacs_mule): Abort if there isn't enough place in
12662 charbuf for the composition carryover bytes. Reserve an extra
12663 space for up to 2 characters produced in a loop.
12664 (decode_coding_iso_2022): Abort if there isn't enough place in
12665 charbuf for the composition carryover bytes.
12667 2011-04-21 Eli Zaretskii <eliz@gnu.org>
12669 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
12670 aborting when %lld or %lll format is passed.
12671 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
12672 %llo or %llx format is passed. (Bug#8545)
12674 * window.c (window_scroll_line_based): Use a marker instead of
12675 simple variables to record original value of point. (Bug#7952)
12677 * doprnt.c (doprnt): Fix the case where a multibyte sequence
12678 produced by %s or %c overflows available buffer space. (Bug#8545)
12680 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
12682 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
12683 (SIZE_MAX): Move defn after all includes, as they might #define it.
12685 2011-04-28 Juanma Barranquero <lekktu@gmail.com>

12695 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
12697 2011-04-28 Eli Zaretskii <eliz@gnu.org>
12699 * doprnt.c (doprnt): Don't return value smaller than the buffer
12700 size if the message was truncated. (Bug#8545).
12702 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
12704 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
12705 (Fx_window_property): #if-0 the whole functions, not just the bodies.
12707 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
12709 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
12711 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
12713 * makefile.w32-in: Update dependencies.
12715 2011-04-27 Eli Zaretskii <eliz@gnu.org>
12717 Improve `doprnt' and its usage. (Bug#8545)
12718 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
12719 `format_end'. Remove support for %l as a conversion specifier.
12720 Don't use xrealloc. Improve diagnostics when the %l size modifier
12721 is used. Update the commentary.
12723 * eval.c (verror): Simplify calculation of size_t.
12725 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
12726 messages.
12728 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
12730 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
12731 change.
12733 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
12735 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
12736 This makes this file independent of the recent pseudovector change.
12738 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
12740 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
12742 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
12743 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
12744 Remove unused local.
12745 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
12747 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
12748 GCC 4.6.0 optimizes based on type-based alias analysis.
12749 For example, if b is of type struct buffer * and v of type struct
12750 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
12751 != &v->size, and therefore "v->size = 1; b->size = 2; return
12752 v->size;" must therefore return 1. This assumption is incorrect
12753 for Emacs, since it type-puns struct Lisp_Vector * with many other
12754 types. To fix this problem, this patch adds a new type struct
12755 vectorlike_header that documents the constraints on layout of vectors
12756 and pseudovectors, and helps optimizing compilers not get fooled
12757 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
12758 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
12759 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
12760 the size member.
12761 (XSETPVECTYPE): Rewrite in terms of new macro.
12762 (XSETPVECTYPESIZE): New macro, specifying both type and size.
12763 This is a bit clearer, and further avoids the possibility of
12764 undesirable aliasing.
12765 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
12766 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
12767 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
12768 since Lisp_Subr is a special case (no "next" field).
12769 (ASIZE): Now uses header.size rather than size.
12770 All previous uses of XVECTOR (foo)->size replaced to use this macro,
12771 to avoid the hassle of writing XVECTOR (foo)->header.size.
12772 (struct vectorlike_header): New type.
12773 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
12774 object, to help avoid aliasing.
12775 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
12776 (SUBRP): Likewise, since Lisp_Subr is a special case.
12777 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
12778 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
12779 (struct Lisp_Hash_Table): Combine first two members into a single
12780 struct vectorlike_header member. All uses of "size" and "next" members
12781 changed to be "header.size" and "header.next".
12782 * buffer.h (struct buffer): Likewise.
12783 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
12784 * frame.h (struct frame): Likewise.
12785 * process.h (struct Lisp_Process): Likewise.
12786 * termhooks.h (struct terminal): Likewise.
12787 * window.c (struct save_window_data, struct saved_window): Likewise.
12788 * window.h (struct window): Likewise.
12789 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
12790 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
12791 * buffer.c (init_buffer_once): Likewise.
12792 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
12793 special case.
12794 * process.c (Fformat_network_address): Use local var for size,
12795 for brevity.
12797 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
12799 Make the Lisp reader and string-to-float more consistent (Bug#8525)
12800 * data.c (atof): Remove decl; no longer used or needed.
12801 (digit_to_number): Move to lread.c.
12802 (Fstring_to_number): Use new string_to_number function, to be
12803 consistent with how the Lisp reader treats infinities and NaNs.
12804 Do not assume that floating-point numbers represent EMACS_INT
12805 without losing information; this is not true on most 64-bit hosts.
12806 Avoid double-rounding errors, by insisting on integers when
12807 parsing non-base-10 numbers, as the documentation specifies.
12808 * lisp.h (string_to_number): New decl, replacing ...
12809 (isfloat_string): Remove.
12810 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
12811 (read1): Do not accept +. and -. as integers; this
12812 appears to have been a coding error. Similarly, do not accept
12813 strings like +-1e0 as floating point numbers. Do not report
12814 overflow for integer overflows unless the base is not 10 which
12815 means we have no simple and reliable way to continue.
12816 Break out the floating-point parsing into a new
12817 function string_to_number, so that Fstring_to_number parses
12818 floating point numbers consistently with the Lisp reader.
12819 (digit_to_number): Move here from data.c. Make it static inline.
12820 (E_CHAR, EXP_INT): Remove, replacing with ...
12821 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
12822 (string_to_number): New function, replacing isfloat_string.
12823 This function checks for valid syntax and produces the resulting
12824 Lisp float number too. Rework it so that string-to-number
12825 no longer mishandles examples like "1.0e+". Use strtoumax,
12826 so that overflow for non-base-10 numbers is reported only when
12827 there's no portable and simple way to convert to floating point.
12829 * textprop.c (set_text_properties_1): Rewrite for clarity,
12830 and to avoid GCC warning about integer overflow.
12832 * intervals.h (struct interval): Use EMACS_INT for members
12833 where EMACS_UINT might cause problems. See
12834 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
12835 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
12836 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
12837 All uses changed.
12838 (offset_intervals): Tell GCC not to worry about length overflow
12839 when negating a negative length.
12841 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
12842 (overrun_check_free): Likewise.
12844 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
12845 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
12846 word size.
12848 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12849 (gnutls_make_error): Rename local to avoid shadowing.
12850 (gnutls_emacs_global_deinit): ifdef out; not used.
12851 (Fgnutls_boot): Use const for pointer to readonly storage.
12852 Comment out unused local. Fix pointer signedness problems.
12854 * lread.c (openp): Don't stuff size_t into an 'int'.
12855 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
12856 about possible signed overflow.
12858 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
12859 (GDK_KEY_g): Don't define if already defined.
12860 (xg_prepare_tooltip): Avoid pointer signedness problem.
12861 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
12863 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
12864 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
12866 * xfns.c (Fx_window_property): Simplify a bit,
12867 to make a bit faster and to avoid GCC 4.6.0 warning.
12868 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
12870 * fns.c (internal_equal): Don't assume size_t fits in int.
12872 * alloc.c (compact_small_strings): Tighten assertion a little.
12874 Replace pEd with more-general pI, and fix some printf arg casts.
12875 * lisp.h (pI): New macro, generalizing old pEd macro to other
12876 conversion specifiers. For example, use "...%"pI"d..." rather
12877 than "...%"pEd"...".
12878 (pEd): Remove. All uses replaced with similar uses of pI.
12879 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
12880 * alloc.c (check_pure_size): Don't overflow by converting size to int.
12881 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
12882 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
12883 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
12884 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
12885 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
12886 64-bit hosts.
12887 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
12888 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
12889 * print.c (safe_debug_print, print_object): Likewise.
12890 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
12891 to int.
12892 Use pI instead of if-then-else-abort. Use %p to avoid casts,
12893 avoiding the 0 flag, which is not portable.
12894 * process.c (Fmake_network_process): Use pI to avoid cast.
12895 * region-cache.c (pp_cache): Likewise.
12896 * xdisp.c (decode_mode_spec): Likewise.
12897 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
12898 behavior on 64-bit hosts with printf arg.
12899 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
12900 (x_stop_queuing_selection_requests): Likewise.
12901 (x_get_window_property): Don't truncate byte count to an 'int'
12902 when tracing.
12904 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
12905 here, since it parses constructs like leading '-' and spaces,
12906 which are not wanted; and it overflows with large numbers.
12907 Instead, simply match F[0-9]+, which is what is wanted anyway.
12909 * alloc.c: Remove unportable assumptions about struct layout.
12910 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
12911 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
12912 (allocate_vectorlike, make_pure_vector): Use the new macros,
12913 plus offsetof, to remove unportable assumptions about struct layout.
12914 These assumptions hold on all porting targets that I know of, but
12915 they are not guaranteed, they're easy to remove, and removing them
12916 makes further changes easier.
12918 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
12919 This doesn't fix a bug but makes the code clearer.
12920 (string_overrun_cookie): Now const. Use initializers that
12921 don't formally overflow signed char, to avoid warnings.
12922 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
12923 can cause Emacs to crash when string overrun checking is enabled.
12924 (allocate_buffer): Don't assume sizeof (struct buffer) is a
12925 multiple of sizeof (EMACS_INT); it need not be, if
12926 alignof(EMACS_INT) < sizeof (EMACS_INT).
12927 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
12929 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
12931 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
12933 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
12935 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
12936 supposed to be handshaking. (Bug#8556)
12937 Reported by Paul Eggert <eggert@cs.ucla.edu>.
12939 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
12941 * lisp.h (Qdebug): List symbol.
12942 * eval.c (Qdebug): Restore global linkage.
12943 * keyboard.c (debug-on-event): New variable.
12944 (handle_user_signal): Break into debugger when debug-on-event
12945 matches the current signal symbol.
12947 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
12949 * alloc.c (check_sblock, check_string_bytes)
12950 (check_string_free_list): Convert to standard C.
12952 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
12954 * w32.c (emacs_gnutls_push): Fix typo.
12956 2011-04-25 Eli Zaretskii <eliz@gnu.org>
12958 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
12959 "cast to pointer from integer of different size".
12961 Improve doprnt and its use in verror. (Bug#8545)
12962 * doprnt.c (doprnt): Document the set of format control sequences
12963 supported by the function. Use SAFE_ALLOCA instead of always
12964 using `alloca'.
12966 * eval.c (verror): Don't limit the buffer size at size_max-1, that
12967 is one byte too soon. Don't use xrealloc; instead xfree and
12968 xmalloc anew.
12970 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
12972 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
12973 callbacks stage.
12975 * gnutls.c: Renamed global_initialized to
12976 gnutls_global_initialized. Added internals for the
12977 :verify-hostname-error, :verify-error, and :verify-flags
12978 parameters of `gnutls-boot' and documented those parameters in the
12979 docstring. Start callback support.
12980 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
12981 unless a fatal error occurred. Call gnutls_alert_send_appropriate
12982 on error. Return error code.
12983 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
12984 (emacs_gnutls_read): Likewise.
12985 (Fgnutls_boot): Return handshake error code.

12998 buffered some data internally if no FDs are set for TLS
12999 connections.

13010 commentary.
13012 * textprop.c (syms_of_textprop): Remove dead code.
13013 (copy_text_properties): Delete obsolete commentary about an
13014 interface that was deleted long ago. Fix typos in the description
13015 of arguments.

13027 * xfaces.c <Qunspecified>: Make extern again.
13029 * syntax.c: Include sys/types.h before including regex.h, as
13030 required by POSIX.

13039 them with etags.
13041 * makefile.w32-in (globals.h): Add a dummy recipe, to make any
13042 changes in globals.h immediately force recompilation.
13043 (TAGS): Depend on $(CURDIR)/m/intel386.h and
13044 $(CURDIR)/s/ms-w32.h.
13045 (TAGS-gmake): Scan $(CURDIR)/m/intel386.h and $(CURDIR)/s/ms-w32.h.
13047 * character.c (Fchar_direction): Function deleted.
13048 (syms_of_character): Don't defsubr it.
13049 <char-direction-table>: Deleted.
13051 2011-04-23 Eli Zaretskii <eliz@gnu.org>
13053 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
13054 * doprnt.c: Include limits.h.
13055 (SIZE_MAX): New macro.
13056 (doprnt): Return a size_t value. 2nd arg is now size_t.
13057 Many local variables are now size_t instead of int or unsigned.
13058 Improve overflow protection. Support `l' modifier for integer
13059 conversions. Support %l conversion. Don't assume an EMACS_INT
13060 argument for integer conversions and for %c.
13062 * lisp.h (doprnt): Restore prototype.
13064 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
13065 $(SRC)/character.h.
13067 * Makefile.in (base_obj): Add back doprnt.o.
13069 * deps.mk (doprnt.o): Add back prerequisites.
13070 (callint.o): Depend on character.h.
13072 * eval.c (internal_lisp_condition_case): Include the handler
13073 representation in the error message.
13074 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
13075 when breaking from the loop.
13077 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
13079 * callint.c (Fcall_interactively): When displaying error message
13080 about invalid control letter, pass the character's codepoint, not
13081 a pointer to its multibyte form. Improve display of the character
13082 in octal and display also its hex code.
13084 * character.c (char_string): Use %x to display the (unsigned)
13085 codepoint of an invalid character, to avoid displaying a bogus
13086 negative value.
13088 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
13089 `error', not SYMBOL_NAME itself.
13091 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
13092 character arguments to `error'.
13094 * charset.c (check_iso_charset_parameter): Fix incorrect argument
13095 to `error' in error message about FINAL_CHAR argument. Make sure
13096 FINAL_CHAR is a character, and use %c when it is passed as
13097 argument to `error'.

13160 * alloc.c (bytes_used_when_full, SPARE_MEMORY, BYTES_USED):
13161 Define only if needed.
13163 * sysdep.c (_FILE_OFFSET_BITS): Make this hack even uglier
13164 by pacifying GCC about it. Maybe it's time to retire it?
13165 * xfaces.c (USG, __TIMEVAL__): Likewise.
13167 * dispextern.h (struct redisplay_interface): Rename param
13168 to avoid shadowing.
13169 * termhooks.h (struct terminal): Likewise.
13170 * xterm.c (xembed_send_message): Likewise.
13172 * insdel.c (make_gap_smaller): Define only if
13173 USE_MMAP_FOR_BUFFERS || REL_ALLOC || DOUG_LEA_MALLOC.
13175 * keyboard.c (read_char): Make a var volatile so longjmp won't clobber
13176 it.
13178 * emacs.c (MAX_HEAP_BSS_DIFF, my_edata): Move to where they're used,
13179 so that we aren't warned about unused symbols.
13181 * xfns.c (Fx_file_dialog): Rename local to avoid shadowing.
13183 * xdisp.c (x_produce_glyphs): Mark var as initialized (Bug#8512).

13213 only if HAVE_X_WINDOWS && !USE_X_TOOLKIT.
13215 * bitmaps: Change bitmaps from unsigned char back to the X11
13216 compatible char. Avoid the old compiler warnings about
13217 out-of-range initializers by using, for example, '\xab' rather
13218 than 0xab.
13220 * xgselect.c (xgselect_initialize): Check vs interface
13221 even if ! (defined (USE_GTK) || defined (HAVE_GCONF)).
13223 * xmenu.c (xmenu_show): Rename parm to avoid shadowing.
13225 * xterm.c (x_create_toolkit_scroll_bar): Use const * for pointers

13243 * xfns.c, xterm.c (_XEditResCheckMessages): Protoize decl.
13245 * xdisp.c, dispextern.h (set_vertical_scroll_bar): Now extern if
13246 USE_TOOLKIT_SCROLL_BARS && !USE_GTK, as xterm.c needs it then.
13248 2011-04-16 Eli Zaretskii <eliz@gnu.org>

13286 * nsfont.m: Fixed bugs in ns_get_family and

13291 --enable-checking=xmallocoverrun). xfree is now used to
13292 deallocate these memory blocks.

13666 (catchlist, handlerlist, mark_backtrace):
13667 Declare only if BYTE_MARK_STACK.
13668 (mark_byte_stack): Likewise, fixing a ifdef-vs-if typo.
13669 * alloc.c (pure): Export only if VIRT_ADDR_VARIES is defined.
13670 (message_enable_multibyte): Remove decl.
13671 (free_misc, interval_free_list, float_block, float_block_index):
13672 (n_float_blocks, float_free_list, cons_block, cons_block_index):
13673 (cons_free_list, last_marked_index):
13674 Now static.
13675 (suppress_checking, die): Define only if ENABLE_CHECKING is defined.
13676 * eval.c (catchlist, handlerlist): Export only if BYTE_MARK_STACK.
13677 (mark_backtrace): Define only if BYTE_MARK_STACK.
13678 * xdisp.c (message_enable_multibyte): Now static.
13680 Declare Lisp_Object Q* variables to be 'static' if not exported.
13681 This makes it easier for human readers (and static analyzers)
13682 to see whether these variables are used from other modules.
13683 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:
13684 * ccl.c, character.c, charset.c, cmds.c, coding.c, composite.c:
13685 * data.c, dbusbind.c, dired.c, editfns.c, eval.c, fileio.c, fns.c:
13686 * font.c, frame.c, fringe.c, ftfont.c, image.c, keyboard.c, keymap.c:
13687 * lread.c, macros.c, minibuf.c, print.c, process.c, search.c:
13688 * sound.c, syntax.c, textprop.c, window.c, xdisp.c, xfaces.c, xfns.c:
13689 * xmenu.c, xselect.c:
13690 Declare Q* vars static if they are not used in other modules.
13691 * ccl.h, character.h, charset.h, coding.h, composite.h, font.h:
13692 * frame.h, intervals.h, keyboard.h, lisp.h, process.h, syntax.h:
13693 Remove decls of unexported vars.
13694 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
13696 * lisp.h (DEFINE_FUNC): Make sname 'static'.
13698 Make Emacs functions such as Fatom 'static' by default.
13699 This makes it easier for human readers (and static analyzers)
13700 to see whether these functions can be called from other modules.
13701 DEFUN now defines a static function. To make the function external
13702 so that it can be used in other C modules, use the new macro DEFUE.
13703 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
13704 (Finit_image_library):
13705 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):
13706 (Ffile_executable_p, Fmake_symbolic_link, Fcommand_execute):
13707 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
13708 Remove decls, since these functions are now static.
13709 (Funintern, Fget_internal_run_time): New decls, since these functions
13710 were already external.
13712 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:
13713 * ccl.c, character.c, chartab.c, cmds.c, coding.c, data.c, dispnew.c:
13714 * doc.c, editfns.c, emacs.c, eval.c, fileio.c, filelock.c, floatfns.c:
13715 * fns.c, font.c, fontset.c, frame.c, image.c, indent.c:
13716 * keyboard.c, keymap.c, lread.c:
13717 * macros.c, marker.c, menu.c, minibuf.c, print.c, process.c, search.c:
13718 * syntax.c, term.c, terminal.c, textprop.c, undo.c:
13719 * window.c, xdisp.c, xfaces.c, xfns.c, xmenu.c, xsettings.c:
13720 Mark functions with DEFUE instead of DEFUN,
13721 if they are used in other modules.
13722 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
13723 decls for now-static functions.
13724 * buffer.h (Fdelete_overlay): Remove decl.
13725 * callproc.c (Fgetenv_internal): Mark as internal.
13726 * composite.c (Fremove_list_of_text_properties): Remove decl.
13727 (Fcomposition_get_gstring): New forward static decl.
13728 * composite.h (Fcomposite_get_gstring): Remove decl.

13730 * doc.c (Fdocumntation_property): New forward static decl.
13731 * eval.c (Ffetch_bytecode): New forward static decl.
13732 (Funintern): Remove extern decl; now in .h file where it belongs.
13733 * fileio.c (Fmake_symbolic_link): New forward static decl.
13734 * image.c (Finit_image_library): New forward static decl.
13735 * insdel.c (Fcombine_after_change_execute): Make forward decl static.
13736 * intervals.h (Fprevious_property_change):
13737 (Fremove_list_of_text_properties): Remove decls.
13738 * keyboard.c (Fthis_command_keys): Remove decl.
13739 (Fcommand_execute): New forward static decl.
13740 * keymap.c (Flookup_key): New forward static decl.
13741 (Fcopy_keymap): Now static.
13742 * keymap.h (Flookup_key): Remove decl.
13743 * process.c (Fget_process): New forward static decl.
13744 (Fprocess_datagram_address): Mark as internal.
13745 * syntax.c (Fsyntax_table_p): New forward static decl.
13746 (skip_chars): Remove duplicate decl.
13747 * textprop.c (Fprevious_property_change): New forward static decl.
13748 * window.c (Fset_window_fringes, Fset_window_scroll_bars):
13749 Now internal.
13750 (Fset_window_margins, Fset_window_vscroll): New forward static decls.
13751 * window.h (Fset_window_vscroll, Fset_window_margins): Remove decls.
13753 * editfns.c (Fformat): Remove unreachable code.
13755 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
13757 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
13758 change. (Bug#8496)
13760 2011-04-13 Eli Zaretskii <eliz@gnu.org>
13762 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
13763 when at ZV. (Bug#8487)
13765 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
13767 * charset.c (Fclear_charset_maps): Use xfree instead of free.
13768 (Bug#8437)
13769 * keyboard.c (parse_tool_bar_item): Likewise.
13770 * sound.c (sound_cleanup, alsa_close): Likewise.
13771 * termcap.c (tgetent): Likewise.
13772 * xfns.c (x_default_font_parameter): Likewise.
13773 * xsettings.c (read_and_apply_settings): Likewise.
13775 * alloc.c (overrun_check_malloc, overrun_check_realloc)
13776 (overrun_check_free): Protoize.
13778 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
13780 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
13781 since callers should never pass a negative size.
13782 Change the signature to match that of plain 'read' and 'write'; see
13783 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
13784 * lisp.h: Update prototypes of emacs_write and emacs_read.
13786 2011-04-11 Eli Zaretskii <eliz@gnu.org>
13788 * xdisp.c (redisplay_window): Don't try to determine the character
13789 position of the scroll margin if the window start point w->startp
13790 is outside the buffer's accessible region. (Bug#8468)
13792 2011-04-10 Eli Zaretskii <eliz@gnu.org>
13794 Fix write-region and its subroutines for buffers > 2GB.
13795 * fileio.c (a_write, e_write): Modify declaration of arguments and
13796 local variables to support buffers larger than 2GB.
13797 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
13799 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
13800 argument, local variables, and return value.
13802 * lisp.h: Update prototypes of emacs_write and emacs_read.
13804 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
13806 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
13808 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
13810 Fix more problems found by GCC 4.6.0's static checks.
13812 * xdisp.c (vmessage): Use a better test for character truncation.
13814 * charset.c (load_charset_map): <, not <=, for optimization,
13815 and to avoid potential problems with integer overflow.
13816 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
13817 * casetab.c (set_identity, shuffle): Likewise.
13818 * editfns.c (Fformat): Likewise.
13819 * syntax.c (skip_chars): Likewise.
13821 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
13822 This also lets GCC 4.6.0 generate slightly better loop code.
13824 * callint.c (Fcall_interactively): <, not <=, for optimization.
13825 (Fcall_interactively): Count the number of arguments produced,
13826 not the number of arguments given. This is simpler and lets GCC
13827 4.6.0 generate slightly better code.
13829 * ftfont.c: Distingish more carefully between FcChar8 and char.
13830 The previous code passed unsigned char * to a functions like
13831 strlen and xstrcasecmp that expect char *, which does not
13832 conform to the C standard.
13833 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
13834 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
13835 char * when the C standard requires it.
13837 * keyboard.c (read_char): Remove unused var.
13839 * eval.c: Port to Windows vsnprintf (Bug#8435).
13840 Include <limits.h>.
13841 (SIZE_MAX): Define if the headers do not.
13842 (verror): Do not give up if vsnprintf returns a negative count.
13843 Instead, grow the buffer. This ports to Windows vsnprintf, which
13844 does not conform to C99. Problem reported by Eli Zaretskii.
13845 Also, simplify the allocation scheme, by avoiding the need for
13846 calling realloc, and removing the ALLOCATED variable.
13848 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
13850 Remove invocations of doprnt, as Emacs now uses vsnprintf.
13851 But keep the doprint source code for now, as we might revamp it
13852 and use it again (Bug#8435).
13853 * lisp.h (doprnt): Remove.
13854 * Makefile.in (base_obj): Remove doprnt.o.
13855 * deps.mk (doprnt.o): Remove.
13857 error: Print 32- and 64-bit integers portably (Bug#8435).
13858 Without this change, on typical 64-bit hosts error ("...%d...", N)
13859 was used to print both 32- and 64-bit integers N, which relied on
13860 undefined behavior.
13861 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
13862 * lisp.h (error, verror): Mark as printf-like functions.
13863 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
13864 Report overflow in size calculations when allocating printf buffer.
13865 Do not truncate output string at its first null byte.
13866 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
13867 Truncate the output at a character boundary, since vsnprintf does not
13868 do that.
13869 * charset.c (check_iso_charset_parameter): Convert internal
13870 character to string before calling 'error', since %c now has the
13871 printf meaning.
13872 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
13873 overflow when computing char to be passed to 'error'. Do not
13874 pass Lisp_Object to 'error'; pass the integer instead.
13875 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
13876 formatted with plain %d.
13878 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
13880 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
13882 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
13884 * xterm.c (x_catch_errors): Remove duplicate declaration.
13886 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
13888 * xdisp.c, lisp.h (message_nolog): Remove; unused.
13890 2011-04-10 Jim Meyering <meyering@redhat.com>
13892 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
13893 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
13894 return ssize_t not "int", and use size_t as the buffer length.
13895 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
13896 * gnutls.h: Update declarations.
13897 * process.c (read_process_output): Use ssize_t, to match.
13898 (send_process): Likewise.
13900 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
13902 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
13904 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
13906 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
13907 Use unsigned char, to match FcChar8 type definition.
13909 * xterm.c (handle_one_xevent):
13910 * xmenu.c (create_and_show_popup_menu):
13911 * xselect.c (x_decline_selection_request)
13912 (x_reply_selection_request): Avoid type-punned deref of X events.
13914 2011-04-09 Eli Zaretskii <eliz@gnu.org>
13916 Fix some uses of `int' instead of EMACS_INT.
13917 * search.c (string_match_1, fast_string_match)
13918 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
13919 (scan_buffer, find_next_newline_no_quit)
13920 (find_before_next_newline, search_command, Freplace_match)
13921 (Fmatch_data): Make some `int' variables be EMACS_INT.
13923 * xdisp.c (display_count_lines): 3rd argument and return value now
13924 EMACS_INT. All callers changed.
13925 (pint2hrstr): Last argument is now EMACS_INT.
13927 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
13928 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)
13929 (detect_coding_ccl, detect_coding_charset, decode_coding_utf_8)
13930 (decode_coding_utf_16, decode_coding_emacs_mule)
13931 (decode_coding_iso_2022, decode_coding_sjis, decode_coding_big5)
13932 (decode_coding_ccl, decode_coding_charset)
13933 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
13934 (decode_coding_iso_2022, decode_coding_emacs_mule)
13935 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
13936 <char_offset, last_offset>: Declare EMACS_INT.
13937 (encode_coding_utf_8, encode_coding_utf_16)
13938 (encode_coding_emacs_mule, encode_invocation_designation)
13939 (encode_designation_at_bol, encode_coding_iso_2022)
13940 (encode_coding_sjis, encode_coding_big5, encode_coding_ccl)
13941 (encode_coding_raw_text, encode_coding_charset) <produced_chars>:
13942 Declare EMACS_INT.
13943 (ASSURE_DESTINATION): Declare more_bytes EMACS_INT.
13944 (encode_invocation_designation): Last argument P_NCHARS is now
13945 EMACS_INT.
13946 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
13947 (produce_chars): from_nchars and to_nchars are now EMACS_INT.
13949 * coding.h (struct coding_system) <head_ascii>: Declare EMACS_INT.
13950 All users changed.
13952 * ccl.c (Fccl_execute_on_string): Declare some variables
13953 EMACS_INT.
13955 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)
13957 * term.c (init_tty): Fix incorrect ifdef placement (Bug#8450).
13959 2011-03-19 Christoph Scholtes <cschol2112@googlemail.com>
13961 * process.c (Fformat_network_address): Doc fix.
13963 2011-04-08 T.V. Raman <tv.raman.tv@gmail.com> (tiny change)
13965 * xml.c (parse_region): Avoid creating spurious whitespace nodes.
13967 2011-04-08 Chong Yidong <cyd@stupidchicken.com>
13969 * keyboard.c (read_char): Call Lisp function help-form-show,
13970 instead of using internal_with_output_to_temp_buffer.
13971 (Qhelp_form_show): New var.
13972 (syms_of_keyboard): Use DEFSYM macro.
13974 * print.c (internal_with_output_to_temp_buffer): Function deleted.
13976 * lisp.h (internal_with_output_to_temp_buffer): Remove prototype.
13978 2011-04-06 Chong Yidong <cyd@stupidchicken.com>
13980 * process.c (Flist_processes): Remove to Lisp.
13981 (list_processes_1): Delete.
13983 2011-04-06 Eli Zaretskii <eliz@gnu.org>
13985 * msdos.c (careadlinkat, careadlinkatcwd): MS-DOS replacements.
13987 * w32.c (careadlinkat, careadlinkatcwd): New always-fail stubs.
13989 2011-04-06 Paul Eggert <eggert@cs.ucla.edu>
13991 Fix more problems found by GCC 4.6.0's static checks.
13993 * xmenu.c (Fx_popup_dialog): Don't assume string is free of formats.
13995 * menu.c (Fx_popup_menu): Don't assume error_name lacks printf formats.
13997 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
13999 * xdisp.c (vmessage): Mark as a printf-like function.
14001 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.
14003 * sound.c (sound_warning): Don't crash if arg contains a printf format.
14005 * image.c (tiff_error_handler, tiff_warning_handler): Mark as
14006 printf-like functions.
14007 (tiff_load): Add casts to remove these marks before passing them
14008 to system-supplied API.
14010 * eval.c (Fsignal): Remove excess argument to 'fatal'.
14012 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
14013 This avoids several warnings with gcc -Wstrict-overflow.
14014 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
14015 directly, rather than having caller test rule sign. This avoids
14016 some unnecessary tests.
14017 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
14018 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
14019 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
14021 * xfont.c (xfont_text_extents): Remove var that was set but not used.
14022 (xfont_open): Avoid unnecessary tests.
14024 * composite.c (composition_gstring_put_cache): Use unsigned integer.
14026 * composite.h, composite.c (composition_gstring_put_cache):
14027 Use EMACS_INT, not int, for length.
14029 * composite.h (COMPOSITION_DECODE_REFS): New macro,
14030 breaking out part of COMPOSITION_DECODE_RULE.
14031 (COMPOSITION_DECODE_RULE): Use it.
14032 * composite.c (get_composition_id): Remove unused local vars,
14033 by using the new macro.
14035 * textprop.c (set_text_properties_1): Change while to do-while,
14036 since the condition is always true at first.
14038 * intervals.c (graft_intervals_into_buffer): Mark var as used.
14039 (interval_deletion_adjustment): Return unsigned value.
14040 All uses changed.
14042 * process.c (list_processes_1, create_pty, read_process_output):
14043 (exec_sentinel): Remove vars that were set but not used.
14044 (create_pty): Remove unnecessary "volatile"s.
14045 (Fnetwork_interface_info): Avoid possibility of int overflow.
14046 (read_process_output): Do adaptive read buffering even if carryover.
14047 (read_process_output): Simplify nbytes computation if buffered.
14049 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
14051 * syntax.c (scan_words): Remove var that was set but not used.
14052 (update_syntax_table): Use unsigned instead of int.
14054 * lread.c (lisp_file_lexically_bound_p): Use ints rather than endptrs.
14055 (lisp_file_lexically_bound_p, read1): Use unsigned instead of int.
14056 (safe_to_load_p): Make the end-of-loop test the inverse of the in-loop.
14058 * print.c (print_error_message): Avoid int overflow.
14060 * font.c (font_list_entities): Redo for clarity,
14061 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
14063 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
14064 (font_score): Avoid potential overflow in diff calculation.
14066 * fns.c (substring_both): Remove var that is set but not used.
14067 (sxhash): Redo loop for clarity and to avoid wraparound warning.
14069 * eval.c (funcall_lambda): Rename local to avoid shadowing.
14071 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
14072 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
14073 can always succeed if overflow has undefined behavior.
14075 * search.c (boyer_moore, wordify): Remove vars set but not used.
14076 (wordify): Omit three unnecessary tests.
14078 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.
14079 All callers changed. This avoids the need for an unused var.
14081 * casefiddle.c (casify_region): Remove var that is set but not used.
14083 * dired.c (file_name_completion): Remove var that is set but not used.
14085 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
14087 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
14088 (Finsert_file_contents): Remove unnecessary code checking fd.
14090 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
14091 Check for integer overflow on size calculations.

14094 but not used.
14096 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
14097 Remove vars that are set but not used.
14098 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
14099 (timer_check_2): Mark vars as initialized.
14101 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
14103 * image.c (lookup_image): Remove var that is set but not used.
14104 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
14106 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
14107 that are set but not used.
14109 * xfns.c (make_invisible_cursor): Don't return garbage
14110 if XCreateBitmapFromData fails (Bug#8410).
14112 * xselect.c (x_get_local_selection, x_handle_property_notify):

14115 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
14116 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
14118 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
14119 Remove var that is set but not used.
14120 (scroll_bar_windows_size): Now size_t, not int.
14121 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
14122 Check for overflow.
14124 * xfaces.c (realize_named_face): Remove vars that are set but not used.
14125 (map_tty_color) [!defined MSDOS]: Likewise.
14127 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
14129 * coding.c: Remove vars that are set but not used.
14130 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
14131 All callers changed.
14132 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):

14139 * print.c (print_object): Remove var that is set but not used.
14141 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
14142 The gnulib version avoids calling malloc in the usual case,
14143 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
14144 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
14145 * filelock.c (current_lock_owner): Likewise.
14146 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
14147 * sysdep.c: Include allocator.h, careadlinkat.h.
14148 (emacs_no_realloc_allocator): New static constant.
14149 (emacs_readlink): New function.
14150 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
14151 ../lib/careadlinkat.h.
14153 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
14155 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
14156 first non-nil return value).
14158 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>

14178 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
14179 (ns_get_family): Likewise.
14181 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
14183 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
14185 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
14187 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
14188 later (Bug#8403).
14190 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
14192 Add lexical binding.
14194 * window.c (Ftemp_output_buffer_show): New fun.
14195 (Fsave_window_excursion):
14196 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
14198 * lread.c (lisp_file_lexically_bound_p): New function.
14199 (Fload): Bind Qlexical_binding.
14200 (readevalloop): Remove `evalfun' arg.
14201 Bind Qinternal_interpreter_environment.
14202 (Feval_buffer): Bind Qlexical_binding.
14203 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
14204 Mark as dynamic.
14205 (syms_of_lread): Declare `lexical-binding'.
14207 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
14209 * keyboard.c (eval_dyn): New fun.
14210 (menu_item_eval_property): Use it.
14212 * image.c (parse_image_spec): Use Ffunctionp.
14214 * fns.c (concat, mapcar1): Accept byte-code-functions.
14216 * eval.c (Fsetq): Handle lexical vars.
14217 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
14218 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
14219 (FletX, Flet): Obey lexical binding.
14220 (Fcommandp): Handle closures.
14221 (Feval): New `lexical' arg.
14222 (eval_sub): New function extracted from Feval. Use it almost
14223 everywhere where Feval was used. Look up vars in lexical env.
14224 Handle closures.
14225 (Ffunctionp): Move from subr.el.
14226 (Ffuncall): Handle closures.
14227 (apply_lambda): Remove `eval_flags'.
14228 (funcall_lambda): Handle closures and new byte-code-functions.
14229 (Fspecial_variable_p): New function.
14230 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
14231 but without exporting it to Lisp.
14233 * doc.c (Fdocumentation, store_function_docstring):
14234 * data.c (Finteractive_form): Handle closures.
14236 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
14237 interactive spec.
14239 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
14240 New byte-codes.
14241 (exec_byte_code): New function extracted from Fbyte_code to handle new
14242 calling convention for byte-code-functions. Add new byte-codes.
14244 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
14246 * alloc.c (Fmake_symbol): Init new `declared_special' field.
14248 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
14250 * xdisp.c (redisplay_internal): Fix prototype.
14252 2011-03-31 Eli Zaretskii <eliz@gnu.org>
14254 * xdisp.c (SCROLL_LIMIT): New macro.
14255 (try_scrolling): Use it when setting scroll_limit.
14256 Limit scrolling to 100 screen lines.
14257 (redisplay_window): Even when falling back on "recentering",
14258 position point in the window according to scroll-conservatively,
14259 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
14261 (try_scrolling): When point is above the window, allow searching
14262 as far as scroll_max, or one screenful, to compute vertical
14263 distance from PT to the scroll margin position. This prevents
14264 try_scrolling from unnecessarily failing when
14265 scroll-conservatively is set to a value slightly larger than the
14266 window height. Clean up the case of PT below the margin at bottom
14267 of window: scroll_max can no longer be INT_MAX. When aggressive
14268 scrolling is in use, don't let point enter the opposite scroll
14269 margin as result of the scroll.
14270 (syms_of_xdisp) <scroll-conservatively>: Document the
14271 threshold of 100 lines for never-recentering scrolling.
14273 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
14275 * dispextern.h (move_it_by_lines):
14276 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused

14278 (message_log_check_duplicate): Remove parameters `prev_bol' and
14279 `this_bol', unused since 1998-01-01T02:27:27Z!rms@gnu.org. All callers changed.
14280 (redisplay_internal): Remove parameter `preserve_echo_area',
14281 unused since 1999-07-21T21:43:52Z!gerd@gnu.org. All callers changed.
14283 * indent.c (Fvertical_motion):
14284 * window.c (window_scroll_pixel_based, Frecenter):
14285 Don't pass `need_y_p' to `move_it_by_lines'.
14287 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
14289 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
14290 steal a few bits to be more compact.

14292 Remove unneeded casts.
14294 * bytecode.c (Fbyte_code): CAR and CDR can GC.
14296 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
14298 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
14299 binding" message (bug#7967).
14301 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>

14305 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
14306 Remove unused local var.
14308 * editfns.c (Fmessage_box): Remove unused local var.
14310 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
14311 (note_mode_line_or_margin_highlight, note_mouse_highlight):
14312 Omit unused local vars.
14313 * window.c (shrink_windows): Omit unused local var.
14314 * menu.c (digest_single_submenu): Omit unused local var.
14315 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
14316 Omit unused local var.
14318 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
14319 Don't assume string length fits in int.
14320 (keyremap_step, read_key_sequence): Use size_t for sizes.

14324 instead of alloca (Bug#8344).
14326 * eval.c (Fbacktrace): Don't assume nargs fits in int.
14327 (Fbacktrace_frame): Don't assume nframes fits in int.
14329 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.

14336 * cm.c (calccost): Turn while-do into do-while, for clarity.
14338 * keyboard.c (syms_of_keyboard): Use the same style as later
14339 in this function when indexing through an array. This also
14340 works around GCC bug 48267.
14342 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
14344 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
14346 * chartab.c (sub_char_table_ref_and_range): Redo for slight
14347 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
14349 * keyboard.c, keyboard.h (num_input_events): Now size_t.
14350 This avoids undefined behavior on integer overflow, and is a bit
14351 more convenient anyway since it is compared to a size_t variable.
14353 Variadic C functions now count arguments with size_t, not int.
14354 This avoids an unnecessary limitation on 64-bit machines, which
14355 caused (substring ...) to crash on large vectors (Bug#8344).

14365 * fns.c (concat): Likewise.
14366 * frame.c (x_set_frame_parameters): Likewise.
14367 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
14368 0 if not found, not -1. All callers changed.
14370 * alloc.c (garbage_collect): Don't assume stack size fits in int.
14371 (stack_copy_size): Now size_t, not int.
14372 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
14374 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
14376 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
14377 unused since 2002-03-01T01:17:24Z!handa@m17n.org and 2008-02-01T16:01:31Z!miles@gnu.org.

14393 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
14394 don't set the hook to nil, but remove the offending function instead.
14395 (Qcommand_hook_internal): Remove, unused.
14396 (syms_of_keyboard): Don't initialize Qcommand_hook_internal nor define
14397 Vcommand_hook_internal.

14538 2011-03-24 Juanma Barranquero <lekktu@gmail.com>
14540 * w32term.c (x_set_glyph_string_clipping):
14541 Don't pass uninitialized region to CombineRgn.
14543 2011-03-23 Juanma Barranquero <lekktu@gmail.com>
14545 * w32fns.c (x_set_menu_bar_lines): Remove unused variable `olines'.

14565 2011-03-23 Julien Danjou <julien@danjou.info>
14567 * term.c (Fsuspend_tty, Fresume_tty):
14568 * minibuf.c (read_minibuf, run_exit_minibuf_hook):
14569 * window.c (temp_output_buffer_show):
14570 * insdel.c (signal_before_change):
14571 * frame.c (Fhandle_switch_frame):
14572 * fileio.c (Fdo_auto_save):

14577 * buffer.c (Fkill_all_local_variables):
14578 * keyboard.c (Fcommand_execute, Fsuspend_emacs, safe_run_hooks_1):
14579 Use Frun_hooks.
14580 (command_loop_1): Use Frun_hooks. Call safe_run_hooks
14581 unconditionally since it does the check itself.
14583 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
14585 Fix more problems found by GCC 4.5.2's static checks.
14587 * coding.c (encode_coding_raw_text): Avoid unnecessary test
14588 the first time through the loop, since we know p0 < p1 then.
14589 This also avoids a gcc -Wstrict-overflow warning.
14591 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
14592 leading to a memory leak, possible in functions like
14593 load_charset_map_from_file that can allocate an unbounded number
14594 of objects (Bug#8318).
14596 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
14597 that could (at least in theory) be that large.
14599 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
14600 This is less likely to overflow, and avoids undefined behavior if
14601 overflow does occur. All callers changed. Use strtoul to scan
14602 for the unsigned long integer.
14603 (pint2hrstr): Simplify and tune code slightly.
14604 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.
14606 * scroll.c (do_scrolling): Work around GCC bug 48228.
14607 See <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=48228>.

14610 This also avoids a warning with gcc -Wstrict-overflow.
14611 (validate_x_resource_name): Simplify count usage.
14612 This also avoids a warning with gcc -Wstrict-overflow.
14614 * fileio.c (Fcopy_file): Report error if fchown or fchmod
14615 fail (Bug#8306).
14617 * emacs.c (Fdaemon_initialized): Do not ignore I/O errors (Bug#8303).
14619 * process.c (Fmake_network_process): Use socklen_t, not int,
14620 where POSIX says socklen_t is required in portable programs.
14621 This fixes a porting bug on hosts like 64-bit HP-UX, where
14622 socklen_t is wider than int (Bug#8277).
14623 (Fmake_network_process, server_accept_connection):
14624 (wait_reading_process_output, read_process_output):
14625 Likewise.
14627 * process.c: Rename or move locals to avoid shadowing.
14628 (list_processes_1, Fmake_network_process):

14634 (FIRST_PROC_DESC, IF_NON_BLOCKING_CONNECT): Remove unused macros.
14635 (create_process): Use 'volatile' to avoid vfork clobbering (Bug#8298).
14637 Make tparam.h and terminfo.c consistent.
14638 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
14639 Include tparam.h instead, since it declares them.
14640 * cm.h (PC): Remove extern decl; tparam.h now does this.
14641 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
14642 * terminfo.c: Include tparam.h, to check interfaces.
14643 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
14644 (tparam): Adjust signature to match interface in tparam.h;
14645 this removes some undefined behavior. Check that outstring and len
14646 are zero, which they always are with Emacs.
14647 * tparam.h (PC, BC, UP): New extern decls.
14649 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
14650 (xftfont_open): Rename locals to avoid shadowing.
14652 * ftfont.c (ftfont_resolve_generic_family): Fix pointer signedness.
14653 (ftfont_otf_capability, ftfont_shape): Omit decls if not needed.
14654 (OTF_TAG_SYM): Omit macro if not needed.
14655 (ftfont_list): Remove unused local.

14662 * xml.c (make_dom): Now static.
14664 * composite.c (composition_compute_stop_pos): Rename local to
14665 avoid shadowing.
14666 (composition_reseat_it): Remove unused locals.
14667 (find_automatic_composition, composition_adjust_point): Likewise.
14668 (composition_update_it): Mark var as initialized.
14669 (find_automatic_composition): Mark vars as initialized,
14670 with a FIXME (Bug#8290).

14674 (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE, FETCH_CHAR_ADVANCE):
14675 (FETCH_CHAR_ADVANCE_NO_CHECK, INC_POS, DEC_POS, BUF_INC_POS):
14676 (BUF_DEC_POS): Be more systematic about renaming local temporaries
14677 to avoid shadowing.
14679 * textprop.c (property_change_between_p): Remove; unused.

14686 Rename locals to avoid shadowing.
14688 * sound.c (wav_play, au_play, Fplay_sound_internal):
14689 Fix pointer signedness.
14690 (alsa_choose_format): Remove unused local var.
14691 (wav_play): Initialize a variable to 0, to prevent undefined
14692 behavior (Bug#8278).
14694 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
14696 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
14698 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
14699 clobbering (Bug#8298).
14700 * sysdep.c (sys_subshell): Likewise.
14701 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
14703 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
14704 This should get cleaned up, so that child_setup has the
14705 same signature on all platforms.
14707 * callproc.c (call_process_cleanup): Now static.
14708 (relocate_fd): Rename locals to avoid shadowing.
14710 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
14712 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
14713 not to be necessary, and produces flickering.
14715 2011-03-20 Glenn Morris <rgm@gnu.org>
14717 * config.in: Remove file.
14719 2011-03-20 Juanma Barranquero <lekktu@gmail.com>
14721 * minibuf.c (Vcompleting_read_function): Don't declare, global variables
14722 are now in src/globals.h.
14723 (syms_of_minibuf): Remove spurious & from previous change.
14725 2011-03-20 Leo Liu <sdl.web@gmail.com>
14727 * minibuf.c (completing-read-function): New variable.
14728 (completing-read-default): Rename from completing-read.
14729 (completing-read): Call completing-read-function.
14731 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
14733 * xfaces.c (Fx_load_color_file):
14734 Read color file from absolute filename (bug#8250).
14736 2011-03-19 Juanma Barranquero <lekktu@gmail.com>
14738 * makefile.w32-in: Update dependencies.
14740 2011-03-17 Eli Zaretskii <eliz@gnu.org>
14742 * makefile.w32-in ($(BLD)/unexw32.$(O)): Depend on $(SRC)/unexec.h.
14744 2011-03-17 Paul Eggert <eggert@cs.ucla.edu>
14746 Fix more problems found by GCC 4.5.2's static checks.
14748 * process.c (make_serial_process_unwind, send_process_trap):
14749 (sigchld_handler): Now static.
14751 * process.c (allocate_pty): Let PTY_ITERATION declare iteration vars.
14752 That way, the code declares only the vars that it needs.
14753 * s/aix4-2.h (PTY_ITERATION): Declare iteration vars.
14754 * s/cygwin.h (PTY_ITERATION): Likewise.
14755 * s/darwin.h (PTY_ITERATION): Likewise.

14762 (CONSTANTLIM): Remove; unused.
14763 (METER_CODE, Bscan_buffer, Bread_char, Bset_mark):
14764 Define only if needed.
14766 * unexelf.c (unexec): Name an expression,
14767 to avoid gcc -Wbad-function-cast warning.
14768 Use a different way to cause a compilation error if anyone uses
14769 n rather than nn, a way that does not involve shadowing.
14770 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
14772 * deps.mk (unexalpha.o): Remove; unused.
14774 New file unexec.h, the (simple) interface for unexec (Bug#8267).
14775 * unexec.h: New file.
14776 * deps.mk (emacs.o, unexaix.o, unexcw.o, unexcoff.o, unexelf.o):
14777 (unexhp9k800.o, unexmacosx.o, unexsol.o, unexw32.o):
14778 Depend on unexec.h.
14779 * emacs.c [!defined CANNOT_DUMP]: Include unexec.h.
14780 * unexaix.c, unexcoff.c, unexcw.c, unexelf.c, unexhp9k800.c:
14781 * unexmacosx.c, unexsol.c, unexw32.c: Include unexec.h.
14782 Change as necessary to match prototype in unexec.h.
14784 * syntax.c (Fforward_comment, scan_lists): Rename locals to avoid
14785 shadowing.
14786 (back_comment, skip_chars): Mark vars as initialized.

14799 * font.c (font_unparse_fcname): Abort in an "impossible" situation
14800 instead of using an uninitialized var.
14801 (font_sort_entities): Mark var as initialized.
14803 * character.h (FETCH_CHAR_ADVANCE): Rename locals to avoid shadowing.
14805 * font.c (font_unparse_xlfd): Don't mix pointers to variables with
14806 pointers to constants.
14807 (font_parse_fcname): Remove unused vars.
14808 (font_delete_unmatched): Now static.

14818 (Ffrexp, Fldexp): Rename locals to avoid shadowing.
14820 * alloc.c (mark_backtrace): Move decl from here ...

14823 * eval.c (call_debugger, do_debug_on_call, grow_specpdl): Now static.
14824 (Fdefvar): Rewrite so as not to use empty "else".

14834 Move decls here, to check interfaces.
14835 * process.c (get_operating_system_release): Move decl to lisp.h.
14836 * xrdb.c (get_system_name): Likewise.
14837 * editfns.c (init_editfns, Fuser_login_name, Fuser_uid):
14838 (Fuser_real_uid, Fuser_full_name): Remove unnecessary casts,
14839 some of which prompt warnings from gcc -Wbad-function-cast.
14840 (Fformat_time_string, Fencode_time, Finsert_char):
14841 (Ftranslate_region_internal, Fformat):
14842 Rename or remove local vars to avoid shadowing.
14843 (Ftranslate_region_internal): Mark var as initialized.
14845 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
14846 avoid shadowing.
14848 * lisp.h (eassert): Check that the argument compiles, even if
14849 ENABLE_CHECKING is not defined.
14851 * data.c (Findirect_variable): Name an expression, to avoid

14860 (Fmake_vector, Fvector, Fmake_byte_code, Fgarbage_collect):
14861 Rename locals to avoid shadowing.
14862 (mark_stack): Move local variables into the #ifdef region where
14863 they're used.
14864 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
14865 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
14866 needed otherwise.
14867 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
14868 (GC_STRING_CHARS): Remove; not used.
14869 (Fmemory_limit): Cast sbrk's returned value to char *.
14871 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
14872 avoids undefined behavior in theory.
14874 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
14876 Use functions, not macros, for up- and down-casing (Bug#8254).
14877 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
14878 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
14879 to use the following functions instead of these macros.
14880 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
14881 EMACS_INT, since callers assume the returned value fits in int.
14882 (upcase1): Likewise, for UPCASE_TABLE.
14883 (uppercasep, lowercasep, upcase): New static inline functions.
14884 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
14885 the race-condition problem in the old DOWNCASE.
14887 * regex.c (CHARSET_LOOKUP_RANGE_TABLE_RAW, POP_FAILURE_REG_OR_COUNT):

14889 (regex_compile, re_match_2_internal): Move locals to avoid shadowing.
14890 (regex_compile, re_search_2, re_match_2_internal):
14891 Remove unused local vars.
14892 (FREE_VAR): Rewrite so as not to use empty "else",
14893 which gcc can warn about.
14894 (regex_compile, re_match_2_internal): Mark locals as initialized.
14895 (RETALLOC_IF): Define only if needed.
14896 (WORDCHAR_P): Likewise. This one is never needed, but is used
14897 only in a comment talking about a compiler bug, so put inside
14898 the #if 0 of that comment.
14899 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
14900 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
14901 Remove; unused.
14903 * search.c (boyer_moore): Rename locals to avoid shadowing.
14904 * character.h (FETCH_STRING_CHAR_AS_MULTIBYTE_ADVANCE):
14905 (PREV_CHAR_BOUNDARY): Likewise.
14907 * search.c (simple_search): Remove unused var.
14909 * dired.c (compile_pattern): Move decl from here ...
14910 * lisp.h: ... to here, so that it can be checked.
14911 (struct re_registers): New forward decl.
14913 * character.h (INC_POS, DEC_POS): Rename locals to avoid shadowing.
14915 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
14916 All uses changed.
14917 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
14918 Rename locals to avoid shadowing.
14919 (Fvertical_motion): Mark locals as initialized.
14921 * casefiddle.c (casify_object, casify_region): Now static.
14922 (casify_region): Mark local as initialized.
14924 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
14926 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
14927 New macros, so that the caller can use some names other than
14928 gcpro1, gcpro2, etc.
14929 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
14930 of the new macros.
14931 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
14932 argument, for consistency with GCPRO2_VAR, etc: it is now the
14933 prefix of the variable, not the variable itself. All uses
14934 changed.
14935 * dired.c (directory_files_internal, file_name_completion):
14936 Rename locals to avoid shadowing.
14938 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
14939 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
14940 dired.c's scmp function, had undefined behavior.
14941 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
14942 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
14943 * buffer.h: ... to here, because these macros use current_buffer,
14944 and the new implementation with inline functions needs to have
14945 current_buffer in scope now, rather than later when the macros
14946 are used.
14947 (downcase, upcase1): New static inline functions.
14948 (DOWNCASE, UPCASE1): Reimplement using these functions.
14949 This avoids undefined behavior in expressions like
14950 DOWNCASE (x) == DOWNCASE (y), which previously suffered
14951 from race conditions in accessing the global variables
14952 case_temp1 and case_temp2.
14953 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
14954 * lisp.h (case_temp1, case_temp2): Remove their decls.
14955 * character.h (ASCII_CHAR_P): Move from here ...
14956 * lisp.h: ... to here, so that the inline functions mentioned
14957 above can use them.
14959 * dired.c (directory_files_internal_unwind): Now static.
14961 * fileio.c (file_name_as_directory, directory_file_name):
14962 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
