1 2012-07-27 Eli Zaretskii <eliz@gnu.org>
3 * alloc.c (listn): Fix the order the arguments are consed onto the
4 list.
6 * lisp.h (enum constype): Use CONSTYPE_HEAP and CONSTYPE_PURE for
7 enumeration constants, as PURE and HEAP are too general, and clash
8 with other headers and sources, such as gmalloc.c and the
9 MS-Windows system headers. All users changed.
11 2012-07-27 Dmitry Antipov <dmantipov@yandex.ru>
13 Revert last save_excursion_save and save_excursion_restore changes.

24 2012-07-27 Paul Eggert <eggert@cs.ucla.edu>
26 Improve GDB symbol export (Bug#12036).
27 * .gdbinit (xgetptr, xgetint, xgettype): Set $bugfix in different
28 arms of an 'if', not using conditional expressions; otherwise GDB
29 complains about the types in the unevaluated arm when the argument
30 is an integer literal.
31 (xgetint): Simplify expression.
32 * alloc.c (gdb_make_enums_visible): New constant. This ports to
33 GCC 3.4.2 the export of symbols to GDB. Problem reported by Eli
34 Zaretskii in <http://bugs.gnu.org/12036#13>.
35 * lisp.h (PUBLISH_TO_GDB): Remove. All uses removed. No longer
36 needed now that we have gdb_make_enums_visible.
37 (enum CHECK_LISP_OBJECT_TYPE, enum Lisp_Bits, enum More_Lisp_Bits)
38 (enum enum_USE_LSB_TAG):
39 New enum types, packaging up enums that need to be exported to GDB.

62 Fast save_excursion_save and save_excursion_restore.
63 * lisp.h (struct Lisp_Excursion): New data type.
64 (PVEC_EXCURSION): New pseudovector type.

79 Fix export of symbols to GDB (Bug#12036).
80 * alloc.c (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL)
81 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Move these here from
82 emacs.c, as this is a more-suitable home. Had this been done earlier
83 the fix for 12036 would have avoided some of the problems noted in
84 <http://bugs.gnu.org/12036#13> by Eli Zaretskii, as the scope problems
85 would have been more obvious.
86 * emacs.c: Do not include <verify.h>; no longer needed.
87 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS)
88 (gdb_GCTYPEBITS, gdb_USE_LSB_TAG)
89 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
90 Remove; now done in lisp.h.

93 (DATA_SEG_BITS): Use it.
94 (GCTYPEBITS, USE_LSB_TAG): Now also an enum, for GDB.
95 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Now just an enum, for GDB.
96 * mem-limits.h (EXCEEDS_LISP_PTR): Redo so that DATA_SEG_BITS need
97 not be usable in #if. This simplifies things.
99 2012-07-26 Juanma Barranquero <lekktu@gmail.com>
101 * makefile.w32-in ($(BLD)/emacs.$(O)): Update dependencies.
103 2012-07-26 Paul Eggert <eggert@cs.ucla.edu>
105 Simplify export of symbols to GDB (Bug#12036).
106 * .gdbinit (xgetptr, xgetint, xgettype): Don't use "set $bugfix =
107 $bugfix.i", as this doesn't work (with GDB 7.4.1, anyway).
108 (xgetptr, xgetint, xgettype, xcoding, xcharset, xprintbytestr):
109 Adjust to changes in lisp.h and emacs.c, by using
110 CHECK_LISP_OBJECT_TYPE rather than gdb_use_struct, VALMASK instead
111 of $valmask, DATA_SEG_BITS instead of gdb_data_seg_bits,
112 INTTYPEBITS instead of gdb_gctypebits - 1, USE_LSB_TAG instead of
113 gdb_use_lsb, (1 << GCTYPEBITS) - 1 instead of $tagmask, VALBITS
114 instead of gdb_valbits.
115 (xvectype, xvector, xpr, xprintstr, xbacktrace): Similarly, use
116 PSEUDOVECTOR_FLAG instead of PVEC_FLAG, and ARRAY_MARK_FLAG
117 instead of gdb_array_mark_flag.
118 (xboolvector): Get size from $->size, not $->header.size.
119 Use BOOL_VECTOR_BITS_PER_CHAR rather than mystery constants.
120 (xreload, hook-run, hookpost-run): Remove.
121 * emacs.c: Include <verify.h>.
122 (gdb_use_lsb, gdb_use_struct, gdb_valbits, gdb_gctypebits)
123 (gdb_data_seg_bits, PVEC_FLAG, gdb_array_mark_flag, gdb_pvec_type):
124 Remove.
125 (gdb_CHECK_LISP_OBJECT_TYPE, gdb_DATA_SEG_BITS, gdb_GCTYPEBITS)
126 (gdb_USE_LSB_TAG): New enum constants.
127 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS, GCTYPEBITS, USE_LSB_TAG):
128 Also define these as enum constants, so they're visible to GDB.
129 (ARRAY_MARK_FLAG_VAL, PSEUDOVECTOR_FLAG_VAL, VALMASK_VAL): New macros.
130 (ARRAY_MARK_FLAG, PSEUDOVECTOR_FLAG, VALMASK): Also define these
131 as constants, so they're visible to GDB.
132 * lisp.h (VALBITS, INTTYPEBITS, FIXNUM_BITS, PSEUDOVECTOR_SIZE_BITS)
133 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK, BOOL_VECTOR_BITS_PER_CHAR):
134 Now enum constants, not macros, so they're visible to GDB.
135 (CHECK_LISP_OBJECT_TYPE, DATA_SEG_BITS): Default to 0, as this is
136 more convenient now. All uses changed.
137 (VALMASK) [USE_LSB_TAG]: Also define in this case.
138 * mem-limits.h (EXCEEDS_LISP_PTR): Adjust to DATA_SEG_BITS change.

145 2012-07-26 Stefan Monnier <monnier@iro.umontreal.ca>
147 * eval.c (Fautoload_do_load): Rename from do_autoload, export to Lisp,
148 add argument, tune behavior, and adjust all callers.
150 2012-07-25 Paul Eggert <eggert@cs.ucla.edu>
152 Use typedef for EMACS_INT, EMACS_UINT.
153 * lisp.h, s/ms-w32.h (EMACS_INT, EMACS_UINT): Use typedefs rather
154 than macros. This simplifies debugging in the usual case, since
155 it lets GDB show addresses as 'EMACS_INT *' rather than 'long int *'
156 and it allows expressions involving EMACS_INT casts.
157 * .gdbinit (xreload): Simplify by using EMACS_INT cast.
159 2012-07-25 Jan Djärv <jan.h.d@swipnet.se>
161 * nsterm.m (ns_read_socket): Return early if there is a modal

171 Adjust buffer text indirection counters at the end of Fkill_buffer.
172 * buffer.c (Fkill_buffer): Adjust indirection counters when the
173 buffer is definitely dead. This should really fix an issue reported
174 by Christoph Scholtes again. (Bug#12007).
175 (init_buffer_once): Initialize indirection counters of
176 buffer_defaults and buffer_local_symbols (for sanity and safety).
178 2012-07-24 Eli Zaretskii <eliz@gnu.org>
180 * xdisp.c (init_iterator): Don't compute dimensions of truncation
181 and continuation glyphs on tooltip frames, leave them at zero.
182 Avoids continued lines in tooltips. (Bug#11832)
184 2012-07-24 Dmitry Antipov <dmantipov@yandex.ru>
186 Simplify copy_overlay.
187 * buffer.c (copy_overlay): Simplify. Use build_marker.

193 or invalid. (Bug#12025)
195 * window.c (decode_any_window): Disable CHECK_LIVE_FRAME test, as
196 it signals an error when a tooltip frame is being created.
198 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>

209 2012-07-23 Dmitry Antipov <dmantipov@yandex.ru>
211 Swap buffer text indirection counters in Fbuffer_swap_text.
212 * buffer.c (Fbuffer_swap_text): Swap indirections too.
213 This avoids crash reported by Christoph Scholtes at
214 http://lists.gnu.org/archive/html/bug-gnu-emacs/2012-07/msg00785.html.
216 2012-07-22 Jan Djärv <jan.h.d@swipnet.se>
218 * nsmenu.m (Popdown_data): New struct.
219 (pop_down_menu): p->pointer is Popdown_data. Release the pool and
220 free Popdown_data.
221 (ns_popup_dialog): Use NSAutoreleasePool and pass it to pop_down_menu.
222 (initWithContentRect): Make imgView and contentView non-static
223 and autorelease them. Also autorelease img and matrix (Bug#12005).

241 2012-07-22 Paul Eggert <eggert@cs.ucla.edu>
243 * buffer.h (struct buffer.indirections): Now ptrdiff_t, not int,
244 as it's limited by the amount of memory, not by INT_MAX.
246 2012-07-21 Eli Zaretskii <eliz@gnu.org>
248 * keyboard.c (keys_of_keyboard): Bind language-change to 'ignore'
249 in special-event-map. See the discussion at
250 http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00417.html
251 for the reasons.
253 * w32menu.c (add_menu_item): Cast to ULONG_PTR when assigning

329 * buffer.h (FOR_EACH_BUFFER): Rename from 'for_each_buffer'.
330 (FOR_EACH_PER_BUFFER_OBJECT_AT): Rename from
331 'for_each_per_buffer_object_at'.
332 All uses changed. It's better to use upper-case for macros that
333 cannot be implemented as functions, to give the reader a clue
334 that they're special.
336 2012-07-19 Stefan Monnier <monnier@iro.umontreal.ca>
338 * alloc.c (Fgarbage_collect): Tweak docstring.

384 2012-07-18 Paul Eggert <eggert@cs.ucla.edu>
386 * alloc.c (Fmake_bool_vector): Fix off-by-8 bug
387 when invoking (make-bool-vector N t) and N is a positive
388 multiple of 8 -- the last 8 bits were mistakenly cleared.
390 Remove some struct layout assumptions in bool vectors.
391 * alloc.c (bool_header_size): New constant.

399 2012-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
401 * eval.c (Fdefvar): Don't check constants since we only set the var if
402 it's not yet defined anyway (bug#11904).
404 * lisp.h (last_undo_boundary): Declare new var.
405 * keyboard.c (command_loop_1): Set it.
406 * cmds.c (Fself_insert_command): Use it to only remove boundaries that
407 were auto-added by the command loop (bug#11774).
409 2012-07-18 Andreas Schwab <schwab@linux-m68k.org>
411 * w32font.c (Qsymbol): Remove local definition.
412 (syms_of_w32font): Don't DEFSYM it.
414 2012-07-18 Dmitry Antipov <dmantipov@yandex.ru>

923 2012-07-11 Dmitry Antipov <dmantipov@yandex.ru>
925 Avoid call to strlen in fast_c_string_match_ignore_case.

972 * s/aix4-2.h (unix): Remove; no longer needed.
974 EMACS_TIME simplification (Bug#11875).
975 This replaces macros (which typically do not work in GDB)
976 with functions, typedefs and enums, making the code easier to debug.
977 The functional style also makes code easier to read and maintain.
978 * systime.h: Include <sys/time.h> on all hosts, not just if
979 WINDOWSNT, since 'struct timeval' is needed in general.
980 (EMACS_TIME): Now a typedef, not a macro.
981 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): Now constants,
982 not macros.
983 (EMACS_SECS, EMACS_NSECS, EMACS_TIME_SIGN, EMACS_TIME_VALID_P)

988 (EMACS_SET_USECS, EMACS_SET_SECS_USECS): Remove these macros,
989 which are not functions. All uses rewritten to use:
990 (make_emacs_time): New function.
991 (EMACS_SECS_ADDR, EMACS_SET_INVALID_TIME, EMACS_GET_TIME)
992 (EMACS_ADD_TIME, EMACS_SUB_TIME): Remove these macros, which are
993 not functions. All uses rewritten to use the following, respectively:
994 (emacs_secs_addr, invalid_emacs_time, get_emacs_time)
995 (add_emacs_time, sub_emacs_time): New functions.
996 * atimer.c: Don't include <sys/time.h>, as "systime.h" does this.
997 * fileio.c (Fcopy_file):
998 * xterm.c (XTflash): Get the current time closer to when it's used.
999 * makefile.w32-in ($(BLD)/atimer.$(O)): Update dependencies.

1008 * lread.c (openp):
1009 * nsmenu.m (ns_update_menubar):
1010 * regex.c (regerror):
1011 Prefer memcpy to strncpy and strncat when either will do.
1012 * fileio.c (Fsubstitute_in_file_name):
1013 * keyboard.c (MULTI_LETTER_MOD, parse_modifiers_uncached)
1014 (menu_separator_name_p):
1015 * nsmenu.m (ns_update_menubar):
1016 Prefer memcmp to strncmp when either will do.
1017 * nsterm.m: Include <ftoastr.h>.
1018 (ns_get_color):
1019 * s/gnu-linux.h, s/sol2-6.h, s/unixware.h (PTY_TTY_NAME_SPRINTF):
1020 Prefer snprintf to strncpy.
1021 * nsterm.m (ns_term_init):
1022 * widget.c (set_frame_size) [0]: Prefer xstrdup to xmalloc + strncpy.
1023 * nsterm.m (ns_term_init):
1024 Avoid the need for strncpy, by using build_string or
1025 make_unibyte_string directly. Use dtoastr, not snprintf.
1026 * process.c (Fmake_network_process): Diagnose service names that
1027 are too long, rather than silently truncating them or creating
1028 non-null-terminated names.
1029 (Fnetwork_interface_info): Likewise, for interface names.
1030 * sysdep.c (system_process_attributes) [GNU_LINUX]:
1031 Prefer sprintf to strncat.
1032 * xdisp.c (debug_method_add) [GLYPH_DEBUG]:
1033 Prefer vsnprintf to vsprintf + strncpy.
1035 2012-07-10 Glenn Morris <rgm@gnu.org>
1037 * dispnew.c (PENDING_OUTPUT_COUNT) [!__GNU_LIBRARY__]:
1038 Clarify fallback case.
1040 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
1042 Use XCAR and XCDR instead of Fcar and Fcdr where possible.
1043 * callint.c, coding.c, doc.c, editfns.c, eval.c, font.c, fontset.c,
1044 * frame.c, gnutls.c, minibuf.c, msdos.c, textprop.c, w32fns.c,
1045 * w32menu.c, window.c, xmenu.c: Change to use XCAR and XCDR
1046 where argument type is known to be a Lisp_Cons.
1048 2012-07-10 Tom Tromey <tromey@redhat.com>
1050 * bytecode.c (BYTE_CODE_THREADED): New macro.

1058 Optimize pure C strings initialization.
1059 * lisp.h (make_pure_string): Fix prototype.
1060 (build_pure_c_string): New function, defined as static inline. This
1061 provides a better opportunity to optimize away calls to strlen when
1062 the function is called with compile-time constant argument.
1063 * alloc.c (make_pure_c_string): Fix comment. Change to add nchars
1064 argument, adjust users accordingly. Use build_pure_c_string where
1065 appropriate.
1066 * buffer.c, coding.c, data.c, dbusbind.c, fileio.c, fontset.c, frame.c,
1067 * keyboard.c, keymap.c, lread.c, search.c, syntax.c, w32fns.c, xdisp.c,
1068 * xfaces.c, xfns.c, xterm.c: Use build_pure_c_string where appropriate.
1070 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
1072 Avoid calls to strlen in miscellaneous functions.
1073 * buffer.c (init_buffer): Use precalculated len, adjust if needed.
1074 * font.c (Ffont_xlfd_name): Likewise. Change to call make_string.
1075 * lread.c (openp): Likewise.
1077 2012-07-10 Dmitry Antipov <dmantipov@yandex.ru>
1079 Avoid calls to strlen in path processing functions.
1080 * fileio.c (file_name_as_directory): Add comment. Change to add
1081 srclen argument and return the length of result. Adjust users
1082 accordingly.
1083 (directory_file_name): Fix comment. Change to add srclen argument,
1084 swap 1st and 2nd arguments to obey the common convention. Adjust
1085 users accordingly.

1094 * s/hpux10-20.h (DATA_SEG_BITS, DATA_START):
1095 * s/gnu.h (DATA_START): Move definitions to configure.
1097 * s/irix6-5.h (SETUP_SLAVE_PTY, PTY_NAME_SPRINTF): Drop ifdef guards.
1098 We include usg5-4-common.h, which defines them both.
1100 * s/gnu.h: Don't include fcntl.h (every file in Emacs that uses
1101 O_RDONLY already includes it).
1103 Stop ns builds setting the EMACSLOADPATH environment variable.
1104 * nsterm.m (ns_load_path): Rename from ns_init_paths.
1105 Now it does not set EMACSLOADPATH, just returns the load-path string.
1106 * nsterm.h: Update accordingly.
1107 * lread.c [HAVE_NS]: Include nsterm.h.
1108 (init_lread) [HAVE_NS]: Use ns_load_path.
1109 * emacs.c (main) [HAVE_NS]: No longer call ns_init_paths.
1111 2012-07-09 Glenn Morris <rgm@gnu.org>
1113 * s/gnu.h (SIGNALS_VIA_CHARACTERS): No need to define it here,
1114 since the included bsd-common.h does so.
1116 Stop ns builds setting the EMACSPATH environment variable.
1117 * nsterm.m (ns_exec_path): New function, split from ns_init_paths.
1118 (ns_init_paths): Do not set EMACSPATH.
1119 * nsterm.h (ns_exec_path): Add it.
1120 * callproc.c (init_callproc_1, init_callproc) [HAVE_NS]:
1121 Use ns_exec_path.
1123 * nsterm.m, nsterm.h (ns_etc_directory): Fix type, empty return.
1125 2012-07-09 Paul Eggert <eggert@cs.ucla.edu>
1127 * process.c (wait_reading_process_output): 'waitchannels' was unset
1128 when read_kbd || !NILP (wait_for_cell); fix this.
1130 Add GCC-style 'const' attribute to functions that can use it.
1131 * character.h (char_resolve_modifier_mask):
1132 * keyboard.h (make_ctrl_char):
1133 * lisp.h (multibyte_char_to_unibyte, multibyte_char_to_unibyte_safe)
1134 (init_character_once, next_almost_prime, init_fns, init_image)
1135 (flush_pending_output, init_sound):

1142 Add decls with ATTRIBUTE_CONST.
1144 Minor improvements to make_formatted_string.
1145 * alloc.c (make_formatted_string): Prefer int to ptrdiff_t
1146 where int is good enough, as vsprintf returns an int.
1147 * lisp.h (make_formatted_string): Add ATTRIBUTE_FORMAT_PRINTF.
1149 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
1151 Use make_formatted_string to avoid double length calculation.
1152 * lisp.h (make_formatted_string): New prototype.

1160 * image.c (gs_load): Likewise.
1161 * minibuf.c (get_minibuffer): Likewise.

1176 2012-07-09 Dmitry Antipov <dmantipov@yandex.ru>
1178 Move marker debugging code under MARKER_DEBUG.
1179 * marker.c (MARKER_DEBUG): Move marker debugging code under
1180 #ifdef MARKER_DEBUG because byte_char_debug_check is too slow
1181 for bootstrap with --enable-checking (~3x slowdown reported
1182 by Juanma Barranquero <lekktu@gmail.com>).
1183 (verify_bytepos): Move under #ifdef MARKER_DEBUG.
1185 2012-07-08 Paul Eggert <eggert@cs.ucla.edu>
1187 * systime.h (EMACS_SUB_TIME): Clarify behavior with unsigned time_t.
1188 See <http://bugs.gnu.org/11825#29>.
1190 2012-07-08 Eli Zaretskii <eliz@gnu.org>
1192 * xdisp.c (fill_glyphless_glyph_string): If the face of the glyph
1193 has no font, use the frame's font. (Bug#11813)
1194 (display_line): Add commentary about displaying truncation glyphs
1195 on GUI frames.
1196 (produce_special_glyphs): Move here from term.c.
1198 * term.c (produce_special_glyphs): Move to xdisp.c.
1200 * dispextern.h (produce_special_glyphs): Move prototype to xdisp.c
1201 section.
1203 2012-07-07 Andreas Schwab <schwab@linux-m68k.org>
1205 * xdisp.c (display_line): Avoid warning about implicit declaration
1206 of FRAME_FONT.
1208 * frame.c (get_frame_param): Define only if HAVE_WINDOW_SYSTEM.
1210 * lisp.h: Remove empty conditional.
1212 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
1214 * lread.c (load_path_check): Now static.
1216 Fix some minor --with-ns problems found by static checking.
1217 * frame.c (Ftool_bar_pixel_width) [!FRAME_TOOLBAR_WIDTH]:
1218 (x_set_font) [!HAVE_X_WINDOWS]:
1219 * image.c (xpm_load_image) [HAVE_NS]:
1220 (x_to_xcolors) [!HAVE_X_WINDOWS && !HAVE_NTGUI]:
1221 (x_disable_image) [!HAVE_NS && !HAVE_NTGUI]:
1222 Remove unused local.
1223 (Fx_parse_geometry) [HAVE_NS]: Don't return garbage.
1224 (xpm_load_image) [HAVE_NS && !HAVE_XPM]: Remove unused label.
1225 * image.c (x_create_bitmap_from_file) [HAVE_NS]:
1226 (xpm_load_image, xpm_load) [HAVE_NS && !HAVE_XPM]:
1227 * nsselect.m (symbol_to_nsstring, ns_string_to_pasteboard_internal):
1228 * xfaces.c (Fx_load_color_file) [!HAVE_X_WINDOWS]:
1229 Fix pointer signedness problem.
1230 * xfaces.c (FRAME_X_FONT_TABLE):
1231 * xterm.h (FRAME_X_FONT_TABLE): Remove unused, incompatible macros.
1233 2012-07-07 Glenn Morris <rgm@gnu.org>
1235 * lread.c (load_path_check): New function, split from init_lread.
1236 (init_lread): Reorganize. Motivation:
1237 If EMACSLOADPATH is set, check/warn about that rather than the
1238 defaults, which we are not going to use. Hence we can remove
1239 the turn_off_warning and WINDOWSNT || HAVE_NS tests.
1240 Don't warn if site-lisp directories are missing.
1241 If not installed, start from a blank load-path, since
1242 PATH_LOADSEARCH refers to the eventual installation directories.
1244 2012-07-07 Eli Zaretskii <eliz@gnu.org>
1246 Support truncation and continuation glyphs on GUI frames, when
1247 fringes are disabled. (Bug#11832)
1248 * xdisp.c (init_iterator): Get dimensions of truncation and
1249 continuation glyphs even if on GUI frames. Adjust
1250 it->last_visible_x on GUI frames when the left or right fringes,
1251 or both, are absent.
1252 (start_display, move_it_in_display_line_to): Handle the case of a
1253 GUI frame without a fringe to display continuation or truncation
1254 glyphs.
1255 (insert_left_trunc_glyphs): Support GUI frames: make sure
1256 truncation glyphs overwrite enough glyphs from the current line to
1257 have sufficient space in pixels.
1258 (display_line): Support truncation and continuation glyphs on GUI
1259 frames. If some spare pixels are left on the line after inserting
1260 the truncation glyphs, fill that space with a stretch glyph of a
1261 suitably computed width.
1263 * term.c (produce_special_glyphs): Call PRODUCE_GLYPHS, not
1264 produce_glyphs, to support GUI sessions.
1266 2012-07-07 Paul Eggert <eggert@cs.ucla.edu>
1268 * sysdep.c (ULLONG_MAX): Define if not already defined (Bug#11781).
1270 * sysdep.c (list_system_processes): Port to NetBSD-current (Bug#11797).
1272 Do not require float-time's arg to fit in time_t (Bug#11825).
1273 This works better on hosts where time_t is unsigned, and where
1274 float-time is applied to the (negative) difference between two times.
1275 * editfns.c (decode_time_components): Last arg is now double *,
1276 not int *, and means to store all the result as a double, without
1277 worrying about whether the seconds part fits in time_t.
1278 All callers changed.
1279 (lisp_time_argument): Remove last int * arg, as it's no longer needed.
1280 All callers changed.
1281 (Ffloat_time): Do not fail merely because the specified time falls
1282 outside of time_t range.
1284 2012-07-07 Glenn Morris <rgm@gnu.org>
1286 * s/darwin.h (HAVE_RES_INIT, HAVE_LIBRESOLV):

1290 2012-07-07 Juanma Barranquero <lekktu@gmail.com>
1292 * makefile.w32-in (DISPEXTERN_H, $(BLD)/regex.$(O)):
1293 Update dependencies.
1295 * s/ms-w32.h [_MSC_VER]: Remove strcasecmp, strncasecmp.
1297 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1299 Use c_strcasecmp for ASCII case-insensitive comparison (Bug#11786).
1300 * dispextern.h, nsfns.m, nsterm.m: Include <c-strcase.h>.
1301 * dispextern.h (xstrcasecmp): Rewrite using c_strcasecmp.
1302 * nsfns.m (x_get_string_resource): Use c_strncasecmp, not strncasecmp.
1303 * nsterm.m (ns_default): Use c_strcasecmp, not strcasecmp.
1304 * xfaces.c (xstrcasecmp) [!HAVE_STRCASECMP]: Remove.
1306 * xfont.c (compare_font_names): Redo to omit the need for casts.
1308 2012-07-06 Andreas Schwab <schwab@linux-m68k.org>
1310 * xfns.c (Fx_change_window_property): Doc fix.
1311 * w32fns.c (Fx_change_window_property): Doc fix.
1313 * w32fns.c (Fx_window_property): Accept the same arguments as the
1314 X Windows version. Doc fix.
1315 * xfns.c (Fx_window_property): Doc fix. (Bug#11870)
1317 2012-07-06 Juanma Barranquero <lekktu@gmail.com>
1318 Eli Zaretskii <eliz@gnu.org>
1320 * s/ms-w32.h: Settings not specific to Windows moved to nt/config.nt.
1321 Windows-specific code from nt/config.nt moved here.
1322 Obsolete settings removed.
1324 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1326 * process.c: Avoid unnecessary calls to gettime.
1327 (wait_reading_process_output): Don't get the time of day
1328 when gobbling data immediately and not waiting, as there's no need
1329 for it in that case. This removes a FIXME.
1331 2012-07-06 Jan Djärv <jan.h.d@swipnet.se>
1333 * gtkutil.c (xg_event_is_for_scrollbar): Assign gwin when HAVE_GTK3
1334 is defined (Bug#11768).
1336 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1338 Fix marker debugging code.
1339 * marker.c (byte_char_debug_check): Do not perform the check
1340 if buffer is not multibyte.
1341 (buf_charpos_to_bytepos, buf_bytepos_to_charpos):
1342 Call byte_char_debug_check with correct arguments.
1344 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1346 Compile marker debugging code only if ENABLE_CHECKING is defined.
1347 * marker.c (byte_char_debug_check, count_markers):
1348 Use only if ENABLE_CHECKING is defined.
1349 (byte_debug_flag): Remove.
1350 (CONSIDER, buf_charpos_to_bytepos, buf_bytepos_to_charpos):
1351 Always call byte_char_debug_check if ENABLE_CHECKING is defined.
1353 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1355 Avoid code repetition in marker-related functions.
1356 * marker.c (attach_marker): New function.
1357 (Fset_marker, set_marker_restricted, set_marker_both)
1358 (set_marker_restricted_both): Use it.
1359 (Fset_marker, set_marker_restricted, Fbuffer_has_markers_at):
1360 Consistently rename charno to charpos.
1361 (marker_position): Add eassert.

1366 Simplify list operations in unchain_overlay and unchain_marker.
1367 * buffer.c (unchain_overlay): Simplify. Add comment.
1368 * marker.c (unchain_marker): Simplify. Fix comments.
1370 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1372 Introduce fast path for the widely used marker operation.
1373 * alloc.c (build_marker): New function.
1374 * lisp.h (build_marker): New prototype.
1375 * buffer.c (clone_per_buffer_values, Fmake_indirect_buffer): Use it.
1376 * composite.c (autocmp_chars): Likewise.
1377 * editfns.c (buildmark): Remove.
1378 (Fpoint_marker, Fpoint_min_marker, Fpoint_max_marker)
1379 (save_restriction_save): Use build_marker.
1380 * marker.c (buf_charpos_to_bytepos, buf_bytepos_to_charpos): Likewise.
1381 * window.c (save_window_save): Likewise.
1383 2012-07-06 Dmitry Antipov <dmantipov@yandex.ru>
1385 Do not use Fdelete_overlay in delete_all_overlays
1386 to avoid redundant calls to unchain_overlay.
1387 * buffer.c (drop_overlay): New function.
1388 (delete_all_overlays, Fdelete_overlay): Use it.
1389 * minibuf.c (get_minibuffer): Fix comment.
1391 2012-07-06 Paul Eggert <eggert@cs.ucla.edu>
1393 Port to OpenBSD 5.1 amd64.
1394 * sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
1395 This is needed for OpenBSD, and should be harmless on all BSD systems.
1396 Also, include <sys/sysctl.h>, as it should be available on all
1397 BSD_SYSTEM hosts given that we're already calling sysctl in that case.
1398 (list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
1399 use p_pid member, not kp_proc.pid.
1401 2012-07-06 Glenn Morris <rgm@gnu.org>
1403 * Makefile.in (emacs$(EXEEXT)): Don't check for load-path shadows.
1405 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
1407 More xmalloc and related cleanup.
1408 * alloc.c, bidi.c, buffer.c, buffer.h, bytecode.c, callint.c:

1412 * gtkutil.c, image.c, keyboard.c, keymap.c, lread.c, macros.c, menu.c:
1413 * nsfns.m, nsfont.m, nsmenu.m, nsterm.m, print.c, process.c, ralloc.c:

1416 * xfaces.c, xfns.c, xftfont.c, xgselect.c, xmenu.c, xrdb.c, xselect.c:
1417 * xterm.c:
1418 Omit needless casts involving void * pointers and allocation.
1419 Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
1420 as the former is more robust if P's type is changed.
1421 Prefer xzalloc to xmalloc + memset 0.
1422 Simplify malloc-or-realloc to realloc.
1423 Don't worry about xmalloc returning a null pointer.
1424 Prefer xstrdup to xmalloc + strcpy.
1425 * editfns.c (Fmessage_box): Grow message_text by at least 80 when
1426 growing it.
1427 * keyboard.c (apply_modifiers_uncached): Prefer local array to
1428 alloca of a constant.
1430 2012-07-05 Eli Zaretskii <eliz@gnu.org>
1432 * xdisp.c (display_line): Fix horizontal pixel coordinates when
1433 hscroll is larger than the line width. Fixes long and futile
1434 looping inside extend_face_to_end_of_line (on a TTY) producing
1435 glyphs that are not needed and thrown away.
1437 2012-07-05 Dmitry Antipov <dmantipov@yandex.ru>
1439 * marker.c (set_marker_restricted_both): Simplify by using
1440 clip_to_bounds.
1442 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
1444 * editfns.c (region_limit): Simplify by using clip_to_bounds.
1446 2012-07-05 Jan Djärv <jan.h.d@swipnet.se>
1448 * gtkutil.c (gtk_scrollbar_new, gtk_box_new): Define when HAVE_GTK3 is
1449 not defined (Bug#11768).
1450 (xg_create_frame_widgets): Use gtk_plug_new_for_display (Bug#11768).
1451 (xg_create_frame_widgets, create_dialog, xg_get_file_with_chooser)
1452 (make_widget_for_menu_item, xg_make_tool_item): Use gtk_box_new
1453 followed by gtk_box_set_homogeneous (Bug#11768).
1454 (xg_update_menu_item): Use GTK_IS_BOX (Bug#11768).
1455 (update_theme_scrollbar_width, xg_create_scroll_bar):
1456 Use gtk_scrollbar_new (Bug#11768).
1457 (xg_event_is_for_scrollbar): Use Gdk Device functions for HAVE_GTK3.
1458 (is_box_type): New function (Bug#11768).
1459 (xg_tool_item_stale_p): Call is_box_type.
1460 (xg_initialize): Get settings by calling gtk_settings_get_for_screen
1461 with default display (Bug#11768).
1463 2012-07-05 Eli Zaretskii <eliz@gnu.org>
1465 * xdisp.c (window_hscroll_limited): New function.
1466 (pos_visible_p, init_iterator): Use it to avoid overflow of pixel
1467 coordinates when window's hscroll is set to insanely large
1468 values. (Bug#11857)
1470 2012-07-05 Juanma Barranquero <lekktu@gmail.com>
1472 * makefile.w32-in ($(BLD)/dired.$(O), $(BLD)/fileio.$(O)): Fix typo.

1531 2012-07-05 Paul Eggert <eggert@cs.ucla.edu>
1533 * fileio.c (time_error_value): Check the right error number.
1534 Problem reported by Troels Nielsen in
1535 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00095.html>.
1537 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1539 * window.c (set_window_hscroll): Revert the 100000 hscroll limit.
1540 This should be fixed in a better way; see Eli Zaretskii in
1541 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
1542 (HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.
1544 * fileio.c (time_error_value): Rename from special_mtime.
1545 The old name's problems were noted by Eli Zaretskii in
1546 <http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00087.html>.
1548 * emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
1549 This variable's comment says Emacs needs at least one GDB-visible
1550 symbol of type enum pvec_type, to work around GDB problems.
1551 The symbol's value doesn't matter.
1553 * alloc.c (PSEUDOVECTOR_NBYTES): Remove stray ';'
1554 that causes compilation to fail on pre-C99 compilers.
1556 2012-07-04 Juanma Barranquero <lekktu@gmail.com>
1558 * s/ms-w32.h (LISP_FLOAT_TYPE, HAVE_MEMCMP, HAVE_MEMCPY)
1559 (HAVE_MEMMOVE, HAVE_MEMSET): Don't set, obsolete.
1561 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
1563 * buffer.c (init_buffer_once): Fix initialization of
1564 headers for buffer_defaults and buffer_local_symbols.
1565 Reported by Juanma Barranquero <lekktu@gmail.com>.
1567 2012-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
1569 Turn VECTOR_FREE_LIST_FLAG into PVEC_FREE.
1570 * lisp.h (enum pvec_type): Use fewer bits.
1571 (PSEUDOVECTOR_SIZE_BITS): New constant.
1572 (PSEUDOVECTOR_SIZE_MASK, PVEC_TYPE_MASK): Use it.
1573 (XSETPVECTYPESIZE, XSETTYPED_PSEUDOVECTOR, DEFUN): Adapt code to
1574 change in pvec_type.
1575 (PSEUDOVECTOR_TYPEP): New macro.
1576 (TYPED_PSEUDOVECTORP): Use it.
1577 * fns.c (internal_equal): Adapt code to extract pvectype.
1578 * emacs.c (gdb_pvec_type): Update type.
1579 * alloc.c (PSEUDOVECTOR_NBYTES): New macro.
1580 (VECTOR_FREE_LIST_SIZE_MASK): Remove (=> PSEUDOVECTOR_SIZE_MASK).
1581 (VECTOR_FREE_LIST_FLAG): Remove (=> PVEC_FREE).
1582 (SETUP_ON_FREE_LIST): Use XSETPVECTYPESIZE.
1583 (sweep_vectors): Use it. Use local var `total_bytes' instead of
1584 abusing vector->header.next.nbytes.
1585 (live_vector_p): Use PVEC_TYPE.
1586 (mark_object): Adapt code to extract pvectype. Use switch.
1588 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1590 * doprnt.c (doprnt): Don't assume string length fits in 'int'.
1591 Tighten new eassert a bit.
1593 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
1595 Fix compilation with --enable-gcc-warnings and -O1
1596 optimization level.
1597 * doprnt.c (doprnt): Change type of tem to int, initialize
1598 to avoid compiler warning. Add eassert.
1599 * search.c (simple_search): Initialize match_byte to avoid
1600 compiler warning. Add eassert.
1602 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1604 Avoid weird behavior with large horizontal scrolls.
1605 Without this change, for example, large hscroll values would
1606 mess up Emacs's display on Fedora 15 x86, presumably due to
1607 overflows in int calculations in the display code.
1608 Also, if buffers had long lines, Emacs would freeze.
1609 * window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
1610 (set_window_hscroll): New function, containing the old guts of
1611 Fset_window_hscroll. Return the clipped value.
1612 (Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
1613 This avoids the need to check against PTRDIFF_MAX.
1615 * buffer.c (Fgenerate_new_buffer_name): Fix sprintf format mismatch.
1617 2012-07-04 Dmitry Antipov <dmantipov@yandex.ru>
1619 * buffer.c (Fgenerate_new_buffer_name): Fix type mismatch.
1621 2012-07-04 Paul Eggert <eggert@cs.ucla.edu>
1623 * regex.c: Suppress GCC warning on RHEL 6. (Bug#11207)
1624 Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
1625 since GCC 4.4.6 issues a bogus warning for them.
1627 Fix bugs in file timestamp newness comparisons.
1628 * fileio.c (Ffile_newer_than_file_p):
1629 * lread.c (Fload): Use full timestamp resolution of files,
1630 not just the 1-second resolution, so that files that are only
1631 slightly newer still count as newer.
1632 * fileio.c (Ffile_newer_than_file_p): Don't assume file
1633 timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.
1635 2012-07-03 Paul Eggert <eggert@cs.ucla.edu>
1637 * fileio.c: Improve handling of file time marker. (Bug#11852)
1638 (special_mtime): New function.
1639 (Finsert_file_contents, Fverify_visited_file_modtime):
1640 Use it to set special mtime values consistently.
1642 2012-07-03 Andreas Schwab <schwab@linux-m68k.org>
1644 * fileio.c (Finsert_file_contents): Properly handle st_mtime
1645 marker for non-existing file. (Bug#11852)
1647 2012-07-03 Glenn Morris <rgm@gnu.org>
1649 * lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
1650 and did not make it into globals.h).
1652 2012-07-03 Tom Tromey <tromey@redhat.com>
1654 * window.c (Fset_window_margins, Fset_window_fringes)
1655 (Fset_window_scroll_bars, Fset_window_vscroll): No longer static.
1656 * textprop.c (Fprevious_property_change): No longer static.
1657 * syntax.c (Fsyntax_table_p): No longer static.
1658 * process.c (Fget_process, Fprocess_datagram_address): No longer
1659 static.
1660 * keymap.c (Flookup_key, Fcopy_keymap): No longer static.
1661 * keyboard.c (Fcommand_execute): No longer static.
1662 Remove EXFUN.
1663 * insdel.c (Fcombine_after_change_execute): No longer static.
1664 * image.c (Finit_image_library): No longer static.

1671 static.
1672 * dired.c (Ffile_attributes): No longer static.
1673 * composite.c (Fcomposition_get_gstring): No longer static.
1674 * callproc.c (Fgetenv_internal): No longer static.
1676 * ccl.h: Remove EXFUNs.
1677 * buffer.h: Remove EXFUNs.
1678 * dispextern.h: Remove EXFUNs.
1679 * intervals.h: Remove EXFUNs.
1680 * fontset.h: Remove EXFUN.
1681 * font.h: Remove EXFUNs.
1682 * dosfns.c (system_process_attributes): Remove EXFUN.
1683 * keymap.h: Remove EXFUNs.
1684 * lisp.h: Remove EXFUNs.
1685 * w32term.h: Remove EXFUNs.
1686 * window.h: Remove EXFUNs.
1687 * xsettings.h: Remove EXFUN.
1688 * xterm.h: Remove EXFUN.
1690 2012-07-03 Glenn Morris <rgm@gnu.org>
1692 * lisp.h (Frandom): Make it visible to C.
1693 * buffer.c (Fgenerate_new_buffer_name): Speed up finding a new
1694 buffer for invisible buffers. (Bug#1229)
1696 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
1698 Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
1699 values which aren't power of 2.
1700 * alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro. Verify
1701 it's value and the value of VECTOR_BLOCK_SIZE. Adjust users
1702 accordingly.
1704 2012-07-03 Stefan Monnier <monnier@iro.umontreal.ca>
1706 * lisp.h (Lisp_Misc, Lisp_Fwd): Move around to group better.
1708 * alloc.c (mark_object): Revert part of last patch to use `switch'.
1710 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
1712 * alloc.c (allocate_vector_block): Remove redundant
1713 calls to mallopt if DOUG_LEA_MALLOC is defined.
1714 (allocate_vectorlike): If DOUG_LEA_MALLOC is defined,
1715 avoid calls to mallopt if zero_vector is returned.
1717 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
1719 * alloc.c (check_string_bytes): If GC_CHECK_STRING_BYTES
1720 is enabled, avoid dereferencing NULL current_sblock if
1721 running undumped.
1723 2012-07-03 Dmitry Antipov <dmantipov@yandex.ru>
1725 Cleanup basic buffer management.
1726 * buffer.h (struct buffer): Change layout to use generic vector
1727 marking code. Fix some comments. Change type of 'clip_changed'
1728 to bitfield. Remove unused #ifndef old.
1729 (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER): Remove.
1730 (GET_OVERLAYS_AT): Fix indentation.
1731 (for_each_per_buffer_object_at): New macro.
1732 * buffer.c (clone_per_buffer_values, reset_buffer_local_variables)
1733 (Fbuffer_local_variables): Use it.
1734 (init_buffer_once, syms_of_buffer): Remove unused #ifndef old.
1735 * alloc.c (allocate_buffer): Adjust to match new layout of
1736 struct buffer. Fix comment.
1737 (mark_overlay): New function.
1738 (mark_buffer): Use it. Use mark_vectorlike to mark normal
1739 Lisp area of struct buffer.
1740 (mark_object): Use it. Adjust marking of misc objects
1741 and related comments.
1743 2012-07-02 Paul Eggert <eggert@cs.ucla.edu>
1745 * alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
1746 wrapper that is not needed because the wrapped code is a no-op (zero
1747 machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
1748 This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.
1750 2012-07-02 Dmitry Antipov <dmantipov@yandex.ru>
1752 * alloc.c (mark_buffer): Simplify. Remove prototype.
1753 (mark_object): Add comment. Reorganize marking of vector-like
1754 objects. Use CHECK_LIVE for all vector-like objects except buffers
1755 and subroutines when GC_CHECK_MARKED_OBJECTS is defined. Avoid
1756 redundant calls to mark_vectorlike for bool vectors.
1758 2012-06-30 Glenn Morris <rgm@gnu.org>
1760 * nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.
1762 * epaths.in (PATH_SITELOADSEARCH): New.
1763 * lread.c (init_lread): Use PATH_SITELOADSEARCH.
1764 This is rather than relying on --enable-locallisppath elements
1765 having "site-lisp" in their names. (Bug#10208#25, 11658)
1767 2012-06-30 Eli Zaretskii <eliz@gnu.org>
1769 * w32proc.c (sys_select): Accept and ignore one more argument.
1771 * w32.c (emacs_gnutls_pull): Call select with one more argument.
1773 * sysselect.h [DOS_NT]: Don't include sys/select.h.
1774 (pselect) [!MS_DOS]: Redirect to sys_select.
1776 * sysdep.c: Don't include dos.h and dosfns.h.
1778 * process.c (sys_select):
1779 * msdos.c (sys_select): Accept one more argument and ignore it.
1781 * msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
1782 adapt data types and code to that.
1784 * dosfns.c:
1785 * msdos.c (gettime, settime): Define away the prototypes in dos.h,
1786 which clashes with the gnulib function of the same name.
1788 2012-06-30 Andreas Schwab <schwab@linux-m68k.org>
1790 * font.c (font_style_to_value, font_style_symbolic)
1791 (font_prop_validate_style): Add type checks for values in
1792 font_style_table.
1794 * lisp.h (CHECK_RANGED_INTEGER): Make value to check the first
1795 argument.
1796 * character.c, charset.c, menu.c, process.c, window.c: Adjust all
1797 uses.
1799 2012-06-29 Eli Zaretskii <eliz@gnu.org>
1801 * xdisp.c (try_window_id): Undo last change.
1803 * w32.c (getwd): Adjust commentary about startup_dir.
1804 (init_environment): Always call sys_access, even in non-MSVC
1805 builds. Don't chdir to the directory of the Emacs executable.
1806 This undoes code from 1997 which was justified by the need to
1807 "avoid conflicts when removing and renaming directories". But its
1808 downside was that every relative file name was being interpreted
1809 relative to the directory of the Emacs executable, which can never
1810 be TRT. In particular, it broke sys_access when called with
1811 relative file names.
1812 (sys_access): Map GetLastError to errno.
1814 2012-06-29 Dmitry Antipov <dmantipov@yandex.ru>

2006 Use sprintf return value instead of invoking strlen on result.
2007 In the old days this wasn't portable, since some sprintf
2008 implementations returned char *. But they died out years ago and
2009 Emacs already assumes sprintf returns int.
2010 Similarly for float_to_string.
2011 This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

2018 * xfns.c (syms_of_xfns):
2019 Use sprintf or float_to_string result to avoid need to call strlen.
2020 * data.c (Fnumber_to_string):
2021 Use make_unibyte_string, since the string must be ASCII.
2022 * lisp.h, print.c (float_to_string): Now returns int length.
2023 * term.c (produce_glyphless_glyph):
2024 Use sprintf result rather than recomputing it.
2026 Clean out last vestiges of the old HAVE_CONFIG_H stuff.
2027 * Makefile.in (ALL_CFLAGS):
2028 * makefile.w32-in (LOCAL_FLAGS): Remove -DHAVE_CONFIG_H.

2050 2012-06-25 Paul Eggert <eggert@cs.ucla.edu>

2053 sprintf already null-terminates its output.
2055 * xfns.c (x_window): Remove redundant cast.
2057 2012-06-25 Dmitry Antipov <dmantipov@yandex.ru>
2059 * xmenu.c (xmenu_show, xdialog_show): Explicit cast from
2060 `const char *' to `char *' to avoid compiler warning.
2062 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
2064 * xterm.c (x_term_init): Build proper-sized _XSETTINGS_Snnn string
2065 instead of truncating it to 63 (admittedly a generous limit).
2067 * process.c: Fix spelling and caps in comments.
2069 2012-06-24 Dan Nicolaescu <dann@ics.uci.edu>

2118 Remove unnecessary forward decls.
2120 2012-06-24 Paul Eggert <eggert@cs.ucla.edu>
2122 Fix bug when time_t is unsigned and as wide as intmax_t (Bug#9000).
2123 * lisp.h (WAIT_READING_MAX): New macro.
2124 * dispnew.c (Fsleep_for, sit_for):
2125 * keyboard.c (kbd_buffer_get_event):
2126 * process.c (Faccept_process_output):
2127 Use it to avoid bogus compiler warnings with obsolescent GCC versions.
2128 This improves on the previous patch, which introduced a bug
2129 when time_t is unsigned and as wide as intmax_t.
2130 See <http://bugs.gnu.org/9000#51>.
2132 2012-06-23 Eli Zaretskii <eliz@gnu.org>

2149 Privately reported by Herbert J. Skuhra.
2150 (make_lisp_timeval) [__FreeBSD__]: Rename from TIMELIST.
2151 All uses changed.
2152 (system_process_attributes) [__FreeBSD__]: Invoke make_lisp_time,
2153 not make_lisp_timeval, when the argument is of type EMACS_TIME.
2155 2012-06-23 Eli Zaretskii <eliz@gnu.org>
2157 * w32proc.c (Fw32_get_locale_info): Fix an off-by-one error in

2161 language ID in the event parameters.
2163 * w32term.c (w32_read_socket): Put the new keyboard codepage into

2195 2012-06-22 Paul Eggert <eggert@cs.ucla.edu>
2197 Support higher-resolution time stamps (Bug#9000).
2198 The time stamps are only nanosecond-resolution at the C level,
2199 since that's the best that any real-world system supports now.
2200 But they are picosecond-resolution at the Lisp level, as that's
2201 easy, and leaves room for future OS improvements.
2203 * Makefile.in (LIB_CLOCK_GETTIME): New macro.
2204 (LIBES): Use it.
2206 * alloc.c (Fgarbage_collect): Port to higher-res time stamps.
2207 Don't get current time unless it's needed.
2209 * atimer.c: Include <sys/time.h> unconditionally, since gnulib
2210 now provides it if it's absent.
2211 (start_atimer): Port to higher-res time stamps.
2212 Check for time stamp overflow. Don't get current time more
2213 often than is needed.
2215 * buffer.h (struct buffer): Buffer modtime now has high resolution.
2216 Include systime.h, not time.h.
2217 (NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.
2219 * dired.c: Include stat-time.h.
2220 (Ffile-attributes): File times now have higher resolution.
2222 * dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
2223 (struct image): Timestamp now has higher resolution.
2225 * dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
2226 has at least microseconds now. All uses removed.
2227 (update_frame, update_single_window, update_window, update_frame_1)
2228 (Fsleep_for, sit_for): Port to higher-resolution time stamps.
2230 * editfns.c (time_overflow): Now extern.
2231 (Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
2232 (float-time, Fformat_time_string, Fcurrent_time_string)
2233 (Fcurrent_time_zone): Accept and generate higher-resolution
2234 time stamps.
2235 (make_time_tail, make_lisp_time, dissassemble_lisp_time)
2236 (decode_time_components, lisp_seconds_argument): New functions.
2237 (make_time): Now static.
2238 (lisp_time_argument): Now returns EMACS_TIME. New arg ppsec.
2239 Report an error if the time is invalid, rather than having the caller
2240 do that.
2242 * fileio.c: Include <stat-time.h>
2243 (Fcopy_file): Copy higher-resolution time stamps.
2244 Prefer to set the time stamp via a file descriptor if that works.
2245 (Fset_file_times, Finsert_file_contents, Fwrite_region)
2246 (Fverify_visited_file_modtime, Fclear_visited_file_modtime)
2247 (Fvisited_file_modtime, Fset_visited_file_modtime):
2248 Support higher-resolution time stamps.
2250 * fns.c (Frandom): Use nanoseconds, not microseconds, for seed.
2252 * gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.
2254 * image.c (prepare_image_for_display, clear_image_cache)
2255 (lookup_image): Port to higer-resolution time stamps.
2257 * keyboard.c (start_polling, bind_polling_period):
2258 Check for time stamp overflow.
2259 (read_char, kbd_buffer_get_event, timer_start_idle)
2260 (timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
2261 (Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
2262 Port to higher-resolution time stamps. Do not assume time_t is signed.
2263 (decode_timer): New function. Timers are now vectors of length 9,
2264 not 8, to accommodate the picosecond component.
2265 (timer_check_2): Use it.
2267 * nsterm.m (select_timeout, timeval_subtract): Remove.
2268 (ns_timeout): Use Emacs's facilities for time stamp arithmetic,
2269 as they're a bit more accurate and handle overflow better.
2270 (ns_select): Change prototype to be compatible with pselect.
2271 (ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
2272 * nsterm.h (ns_select): Adjust prototype.
2274 * msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
2275 us-resolution time stamps.
2276 (sys_select): Use the new EMACS_TIME_SIGN macro instead.
2278 * lread.c (read_filtered_event): Port to ns-resolution time stamps.
2280 * lisp.h (time_overflow): New decl.
2281 (wait_reading_process_output): First arg is now intmax_t, not int,
2282 to accommodate larger waits.
2284 * process.h (struct Lisp_Process.read_output_delay):
2285 Now counts nanoseconds, not microseconds.
2286 * process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
2287 EMACS_HAS_USECS.
2288 (READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
2289 (wait_reading_process_output):
2290 Port to ns-resolution time stamps.
2291 (Faccept_process_output, wait_reading_process_output):
2292 Check for time stamp overflow. Do not assume time_t is signed.
2293 (select_wrapper): Remove; we now use pselect.
2294 (Fprocess_attributes): Now generates ns-resolution time stamps.
2296 * sysdep.c: Include utimens.h. Don't include utime.h
2297 or worry about struct utimbuf; gnulib does that for us now.
2298 (gettimeofday): Remove; gnulib provides a substitute.
2299 (make_timeval): New function.
2300 (set_file_times): Now sets ns-resolution time stamps.
2301 New arg FD; all uses changed.
2302 (time_from_jiffies, ltime_from_jiffies, get_up_time)
2303 (system_process_attributes):
2304 Now returns ns-resolution time stamp. All uses changed.
2305 Check for time stamp overflow.
2307 * sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
2308 provides a substitute now.
2310 * systime.h: Include timespec.h rather than sys/time.h and time.h,
2311 since it guarantees struct timespec.
2312 (EMACS_TIME): Now struct timespec, so that we can support
2313 ns-resolution time stamps.
2314 (EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
2315 (EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
2316 (EMACS_USECS): Remove.
2317 (EMACS_SET_USECS): The underlying time stamp now has ns resolution,
2318 so multiply the arg by 1000 before storing it.
2319 (EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
2320 New macros.
2321 (EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
2322 Port to ns-resolution time stamps.
2323 (EMACS_TIME_NEG_P): Remove; replaced by....

2326 (EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
2327 (set_file_times, make_time, lisp_time_argument): Adjust signature.
2328 (make_timeval, make_lisp_time, decode_time_components): New decls.
2329 (EMACS_TIME_CMP): Remove; no longer used. Plus, it was buggy, in
2330 that it mishandled time_t overflow. You can't compare by subtracting!
2331 (EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
2332 (EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.
2334 * term.c: Include <sys/time.h>.
2335 (timeval_to_Time): New function, for proper overflow wraparound.
2336 (term_mouse_position, term_mouse_click): Use it.
2338 * undo.c (record_first_change): Support higher-resolution time stamps
2339 in the undo buffer.
2340 (Fprimitive_undo): Use them when restoring time stamps.
2342 * w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
2343 (w32_get_internal_run_time):
2344 Port to higher-resolution Emacs time stamps.
2345 (ltime): Now accepts single 64-bit integer, as that's more convenient
2346 for callers.
2348 * xdisp.c (start_hourglass): Port to ns-resolution time stamps.
2350 * xgselect.c, xgselect.h (xg_select): Add sigmask argument,
2351 for compatibility with pselect. Support ns-resolution time stamps.
2353 * xmenu.c (x_menu_wait_for_event): Support ns-resolution time stamps.
2355 * xselect.c (wait_for_property_change, x_get_foreign_selection):
2356 Check for time stamp overflow, and support ns-resolution time stamps.
2358 * xterm.c: Don't include sys/time.h; gnulib does that for us now.
2359 Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
2360 (timeval_subtract): Remove; no longer needed.
2361 (XTflash, XTring_bell, x_wait_for_event):
2362 Port to ns-resolution time stamps. Don't assume time_t is signed.
2364 2012-06-22 Chong Yidong <cyd@gnu.org>
2366 * xdisp.c (x_consider_frame_title): Revert last change.
2368 2012-06-22 Eli Zaretskii <eliz@gnu.org>
2370 * alloc.c (NSTATICS): Enlarge to 0x650. Otherwise, Emacs compiled
2371 with -DENABLE_CHECKING -DXASSERTS -DGLYPH_DEBUG=1 -DBYTE_CODE_METER
2372 aborts in staticpro during startup. (Without -DBYTE_CODE_METER,
2373 staticidx goes up to 1597 out of 1600 = 0x640.)
2375 2012-06-20 Paul Eggert <eggert@cs.ucla.edu>
2377 * fileio.c (Fdefault_file_modes): Block input while fiddling with umask.
2378 Otherwise, the umask might be mistakenly 0 while handling input signals.
2380 2012-06-19 Stefan Monnier <monnier@iro.umontreal.ca>
2382 * minibuf.c (Fread_string): Bind minibuffer-completion-table.
2384 2012-06-19 Dmitry Antipov <dmantipov@yandex.ru>
2386 * alloc.c, bytecode.c, ccl.c, coding.c, composite.c, data.c, dosfns.c:
2387 * font.c, image.c, keyboard.c, lread.c, menu.c, minibuf.c, msdos.c:
2388 * print.c, syntax.c, window.c, xmenu.c, xselect.c: Replace direct
2389 access to `contents' member of Lisp_Vector objects with AREF and ASET
2390 where appropriate.
2392 2012-06-19 Chong Yidong <cyd@gnu.org>
2394 * frame.c (delete_frame): When selecting a frame on a different
2395 text terminal, do not alter the terminal's top-frame.
2397 * xdisp.c (format_mode_line_unwind_data): Record the target
2398 frame's selected window and its terminal's top-frame.
2399 (unwind_format_mode_line): Restore them.
2400 (x_consider_frame_title, display_mode_line, Fformat_mode_line):
2401 Callers changed.
2402 (x_consider_frame_title): Do not condition on HAVE_WINDOW_SYSTEM,
2403 since tty frames can be explicitly named.
2404 (prepare_menu_bars): Likewise.
2406 * term.c (Ftty_top_frame): New function.
2408 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
2410 Port byte-code-meter to modern targets.
2411 * bytecode.c (METER_CODE) [BYTE_CODE_METER]: Don't assume
2412 !CHECK_LISP_OBJECT_TYPE && !USE_LSB_TAG. Problem with
2413 CHECK_LISP_OBJECT_TYPE reported by Dmitry Antipov in
2414 <http://lists.gnu.org/archive/html/emacs-devel/2012-06/msg00282.html>.
2415 (METER_1, METER_2): Simplify.
2417 2012-06-18 Stefan Monnier <monnier@iro.umontreal.ca>
2419 * data.c (Fdefalias): Return `symbol' (bug#11686).
2421 2012-06-18 Martin Rudalics <rudalics@gmx.at>
2423 * buffer.c (Fkill_buffer): Don't throw an error when the buffer
2424 gets killed during executing of this function (Bug#11665).
2425 Try to always return Qt when the buffer has been actually killed.
2426 (Vkill_buffer_query_functions): In doc-string say that functions
2427 run by this hook should not change the current buffer.
2429 2012-06-18 Paul Eggert <eggert@cs.ucla.edu>
2431 Fix recently-introduced process.c problems found by static checking.
2432 * process.c (write_queue_push, write_queue_pop, send_process):
2433 Use ptrdiff_t, not int or EMACS_INT, for buffer lengths and offsets.
2434 (write_queue_pop): Fix pointer signedness problem.
2435 (send_process): Remove unused local.
2437 2012-06-17 Chong Yidong <cyd@gnu.org>
2439 * xdisp.c (redisplay_internal): No need to redisplay terminal
2440 frames that are not on top.
2442 2012-06-17 Troels Nielsen <bn.troels@gmail.com>
2444 * process.c (make_process): Initialize write_queue.
2445 (write_queue_push, write_queue_pop): New functions.

2447 writes (Bug#10815).
2449 2012-06-17 Paul Eggert <eggert@cs.ucla.edu>
2451 * lisp.h (eassert): Assume C89 or later.
2452 This removes the need for CHECK.
2453 (CHECK): Remove. Its comments about always evaluating its
2454 argument were confusing, as 'eassert' typically does not evaluate
2455 its argument.
2457 * coding.c (produce_chars): Use ptrdiff_t, not int.
2459 * xterm.c (x_draw_underwave): Check for integer overflow.
2460 This pacifies gcc 4.7.0 -Wunsafe-loop-optimizations on x86-64.

2481 * xterm.c (x_draw_underwave): New function.
2482 (x_draw_glyph_string): Use it.
2484 2012-06-16 Juanma Barranquero <lekktu@gmail.com>

2553 * xdisp.c (set_cursor_from_row): Don't dereference glyphs_end.
2554 If all the glyphs of the glyph row came from strings, and we have no
2555 cursor positioning clues, put the cursor on the first glyph of the
2556 row.
2557 (handle_face_prop): Use chunk-relative overlay string index when
2558 indexing into it->string_overlays array. (Bug#11653)

2576 * .gdbinit (xgetint): Fix recently-introduced paren typo.
2577 Assume USE_2_TAGS_FOR_INTS.
2578 (xreload): Adjust $tagmask width to match recent lisp.h change.
2580 Simplify lisp.h in minor ways that should not affect code.
2581 * lisp.h (USE_2_TAGS_FOR_INTS): Remove, as it was always defined.
2582 (LISP_INT_TAG, case_Lisp_Int, LISP_STRING_TAG, LISP_INT_TAG_P)
2583 (LISP_INT1_TAG, enum Lisp_Type, XINT, XUINT, make_number):

2601 2012-06-13 Andreas Schwab <schwab@linux-m68k.org>
2603 * lisp.h (Lisp_Object) [CHECK_LISP_OBJECT_TYPE]: Define as struct
2604 instead of union.
2605 (XLI, XIL): Define.
2606 (XHASH, XTYPE, XINT, XUINT, make_number, XSET, XPNTR, XUNTAG):
2607 Use them.
2608 * emacs.c (gdb_use_struct): Rename from gdb_use_union.

2644 (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
2645 code works fine either way, and efficiency is not a concern here,
2646 as the union type is for debugging, not for production.
2647 (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
2648 Use an inline function on all platforms when using the union type,
2649 since this is simpler and 'static inline' can be used portably
2650 within Emacs now.
2651 (LISP_INITIALLY_ZERO): New macro.
2652 (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.

2753 2012-06-08 Juanma Barranquero <lekktu@gmail.com>
2755 * dispnew.c (showing_window_margins_p): Wrap in #if 0 to prevent unused
2756 function warning (the only call is inside #if 0 since revno:108521).
2758 2012-06-08 Eli Zaretskii <eliz@gnu.org>
2760 * alloc.c (allocate_vectorlike): Fix last change.
2762 2012-06-08 Dmitry Antipov <dmantipov@yandex.ru>
2764 Block-based vector allocation of small vectors.
2765 * lisp.h (struct vectorlike_header): New field `nbytes',
2766 adjust comment accordingly.
2767 * alloc.c (enum mem_type): New type `MEM_TYPE_VECTOR_BLOCK'
2768 to denote vector blocks. Adjust users (live_vector_p,
2769 mark_maybe_pointer, valid_lisp_object_p) accordingly.
2770 (COMMON_MULTIPLE): Move outside #if USE_LSB_TAG.
2771 (VECTOR_BLOCK_SIZE, vroundup, VECTOR_BLOCK_BYTES),
2772 (VBLOCK_BYTES_MIN, VBLOCK_BYTES_MAX, VECTOR_MAX_FREE_LIST_INDEX),
2773 (VECTOR_FREE_LIST_FLAG, ADVANCE, VINDEX, SETUP_ON_FREE_LIST),
2774 (VECTOR_SIZE, VECTOR_IN_BLOCK): New macros.
2775 (roundup_size): New constant.
2776 (struct vector_block): New data type.
2777 (vector_blocks, vector_free_lists, zero_vector): New variables.
2778 (all_vectors): Rename to `large_vectors'.
2779 (allocate_vector_from_block, init_vectors, allocate_vector_from_block)
2780 (sweep_vectors): New functions.
2781 (allocate_vectorlike): Return `zero_vector' as the only vector of
2782 0 items. Allocate new vector from block if vector size is less than
2783 or equal to VBLOCK_BYTES_MAX.
2784 (Fgarbage_collect): Move all vector sweeping code to sweep_vectors.
2785 (init_alloc_once): Add call to init_vectors.
2787 2012-06-08 Stefan Monnier <monnier@iro.umontreal.ca>
2789 * eval.c (Fmacroexpand): Stop if the macro returns the same form.
2791 2012-06-07 Paul Eggert <eggert@cs.ucla.edu>
2793 * doprnt.c (doprnt): Truncate multibyte char correctly.
2794 Without this change, doprnt (buf, 2, "%s", FORMAT_END, AP)
2795 would mishandle a string argument "Xc" if X was a multibyte
2796 character of length 2: it would truncate after X's first byte
2797 rather than including all of X.
2799 2012-06-06 Chong Yidong <cyd@gnu.org>
2801 * buffer.c (word_wrap): Doc fix.
2803 2012-06-04 Paul Eggert <eggert@cs.ucla.edu>

2815 binary via PaX flags if the paxctl utility is available.
2816 (emacs$(EXEEXT), bootstrap-emacs$(EXEEXT)):
2817 Restore PaX flags to their default. (Bug#11398)
2819 2012-06-03 Chong Yidong <cyd@gnu.org>
2821 * xdisp.c (decode_mode_spec_coding): Display a space for a unibyte

2826 * xdisp.c (calc_pixel_width_or_height): Use Fbuffer_local_value.
2827 (note_mode_line_or_margin_highlight): If there is no help echo,
2828 use mode-line-default-help-echo. Handle the case where the mouse
2829 position is past the end of the mode line string.
2831 * buffer.c (buffer_local_value_1): New function, split from
2832 Fbuffer_local_value; can return Qunbound.
2833 (Fbuffer_local_value): Use it.
2834 (Vmode_line_format): Docstring tweaks.
2836 2012-06-02 Paul Eggert <eggert@cs.ucla.edu>

2848 * minibuf.c (Fassoc_string): Remove duplicate declaration.
2850 * sysdep.c (system_process_attributes) [SOLARIS2 && HAVE_PROCFS]:
2851 Convert pctcpu and pctmem to Lisp float properly.
2852 Let the compiler fold better, as 100.0/0x8000 is exact.
2854 2012-06-02 Andreas Schwab <schwab@linux-m68k.org>
2856 * alloc.c (CONS_BLOCK_SIZE): Account for padding at the end of
2857 cons_block.
2859 2012-06-01 Paul Eggert <eggert@cs.ucla.edu>
2861 * xfns.c (x_set_tool_bar_lines) [USE_GTK]: Adjust to bitfield change.
2863 2012-06-01 Dmitry Antipov <dmantipov@yandex.ru>
2865 For a 'struct window', replace some Lisp_Object fields to
2866 bitfields where appropriate, remove unused fields.
2867 * window.h (struct window): Remove unused 'last_mark_x' and
2868 'last_mark_y' fields. Rename 'mini_p' field to 'mini',
2869 change it's type from Lisp_Object to bitfield.
2870 Change type of 'force_start', 'optional_new_start',
2871 'last_had_star', 'update_mode_line' and 'start_at_line_beg'
2872 fields from Lisp_Object to bitfield. Adjust users accordingly.
2874 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
2876 Pacify gcc -Wdouble-precision when using Xaw.
2877 * xterm.c (xaw_jump_callback, x_set_toolkit_scroll_bar_thumb)
2878 [HAVE_X_WINDOWS && USE_TOOLKIT_SCROLL_BARS && !USE_MOTIF && !USE_GTK]:
2879 Use 'float' consistently, rather than 'float' in most places
2880 and 'double' in a couple of places.
2882 2012-05-31 Eli Zaretskii <eliz@gnu.org>
2884 * xdisp.c (handle_stop): Detect whether we have overlay strings
2885 loaded by testing it->current.overlay_string_index to be
2886 non-negative, instead of checking whether n_overlay_strings is
2887 positive. (Bug#11587)
2889 2012-05-31 Chong Yidong <cyd@gnu.org>
2891 * keymap.c (describe_map_tree): Revert 2011-07-07 change (Bug#1169).
2893 * doc.c (Fsubstitute_command_keys): Doc fix.
2895 2012-05-31 Eli Zaretskii <eliz@gnu.org>
2897 * search.c (search_buffer): Remove calls to
2898 r_alloc_inhibit_buffer_relocation, as it is now called by
2899 maybe_unify_char, which was the cause of relocation of buffer text
2900 in bug#11519.
2902 2012-05-31 Eli Zaretskii <eliz@gnu.org>
2904 * charset.c (maybe_unify_char): Inhibit relocation of buffer text
2905 for the duration of call to load_charset, to avoid problems with
2906 callers of maybe_unify_char that access buffer text through C
2907 pointers.
2909 * ralloc.c (r_alloc_inhibit_buffer_relocation): Increment and
2910 decrement the inhibition flag, instead of just setting or
2911 resetting it.
2913 2012-05-31 Paul Eggert <eggert@cs.ucla.edu>
2915 Remove obsolete '#define static' cruft.
2916 * s/hpux10-20.h (_FILE_OFFSET_BITS): Don't #undef.
2917 This #undef was "temporary" in 2000; it is no longer needed
2918 now that '#define static' has gone away.
2919 * xfns.c, xterm.h (gray_bitmap_width, gray_bitmap_height)
2920 (gray_bitmap_bits): Remove; no longer needed.
2921 All uses replaced with definiens.
2922 * xterm.c: Include "bitmaps/gray.xbm".
2924 2012-05-30 Paul Eggert <eggert@cs.ucla.edu>
2926 Clean up __executable_start, monstartup when --enable-profiling.
2927 The following changes affect the code only when profiling.
2928 * dispnew.c (__executable_start): Rename from safe_bcopy.
2929 Define only on platforms that need it.
2930 * emacs.c: Include <sys/gmon.h> when profiling.
2931 (_mcleanup): Remove decl, since <sys/gmon.h> does it now.
2932 (__executable_start): Remove decl, since lisp.h does it now.
2933 (safe_bcopy): Remove decl; no longer has that name.
2934 (main): Coalesce #if into single bit of code, for simplicity.
2935 Cast pointers to uintptr_t, since standard libraries want integers
2936 and not pointers.
2937 * lisp.h (__executable_start): New decl.
2939 2012-05-31 Glenn Morris <rgm@gnu.org>
2941 * image.c (Fimagemagick_types): Doc fix.
2943 2012-05-30 Jim Meyering <meyering@redhat.com>
2945 * callproc.c (Fcall_process_region): Include directory component

2962 2012-05-29 Troels Nielsen <bn.troels@gmail.com>
2964 Do not create empty overlays with the evaporate property (Bug#9642).
2965 * buffer.c (Fmove_overlay): Reinstate the earlier fix for
2966 Bug#9642, but explicitly check that the buffer the overlay would
2967 be moved to is live and rearrange lines to make sure that errors
2968 will not put the overlay in an inconsistent state.
2969 (Fdelete_overlay): Cosmetics.
2971 2012-05-28 Eli Zaretskii <eliz@gnu.org>
2973 * w32term.c (my_bring_window_to_top): New function.
2974 (x_raise_frame): Use handle returned by DeferWindowPos, which
2975 could be different from the original one.
2976 Call my_bring_window_to_top instead of my_set_foreground_window.
2977 (Bug#11513)
2979 * w32fns.c (w32_wnd_proc): Accept and process WM_EMACS_BRINGTOTOP
2980 by calling BringWindowToTop.

2983 (WM_EMACS_END): Increase by one.
2985 2012-05-28 Paul Eggert <eggert@cs.ucla.edu>
2987 * bidi.c (bidi_mirror_char): Put eassert before conversion to int.
2988 This avoids undefined behavior that might cause the eassert
2989 to not catch an out-of-range value.
2991 2012-05-28 Juanma Barranquero <lekktu@gmail.com>
2993 * makefile.w32-in ($(BLD)/w32inevt.$(O), $(BLD)/w32console.$(O)):
2994 Update dependencies.
2996 2012-05-27 Eli Zaretskii <eliz@gnu.org>

3005 2012-05-27 Paul Eggert <eggert@cs.ucla.edu>
3007 * lisp.h [REL_ALLOC]: Omit duplicate prototypes.
3008 Only r_alloc_inhibit_buffer_relocation needed to be added;
3009 the others were already declared.
3011 * bidi.c (bidi_mirror_char): Don't possibly truncate the integer
3012 before checking whether it's out of range. Put the check inside
3013 eassert. See
3014 <http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.
3016 2012-05-27 Ken Brown <kbrown@cornell.edu>
3018 * callproc.c (Fcall_process): Restore a line that was accidentally
3019 commented out in the 2011-02-13 change (bug#11547).
3021 2012-05-27 Eli Zaretskii <eliz@gnu.org>
3023 * lisp.h [REL_ALLOC]: Add prototypes for external functions
3024 defined on ralloc.c.
3026 * buffer.c [REL_ALLOC]: Remove prototypes of
3027 r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
3028 they are now on lisp.h.
3030 * ralloc.c (r_alloc_inhibit_buffer_relocation): New function.
3032 * search.c (search_buffer): Use it to inhibit relocation of buffer
3033 text while re_search_2 is doing its job, because re_search_2 is
3034 passed C pointers to buffer text. (Bug#11519)
3036 * msdos.c (internal_terminal_init) <Vwindow_system_version>:
3037 Update value to 24.
3039 * xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
3040 state after an additional call to move_it_in_display_line_to, keep
3041 the values of it->max_ascent and it->max_descent found for the
3042 entire line.
3043 (pos_visible_p): Revert the comparison against bottom_y to what it
3044 was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
3045 (Bug#11464)
3047 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3049 Fix coding-related core dumps with gcc -ftrapv.
3050 The code was computing A - B, where A and B are pointers, and B is
3051 random garbage. This can lead to core dumps on platforms that
3052 have special pointer registers, and it also leads to core dumps on
3053 x86-64 when compiled with gcc -ftrapv. The fix is to compute
3054 A - B only when B is initialized properly.
3055 * coding.c (coding_set_source, coding_set_destination): Return void.
3056 (coding_change_source, coding_change_destinations): New functions,
3057 with the old behaviors of coding_set_source and coding_set_destination.
3058 All callers that need an offset changed to use these new functions.
3060 2012-05-26 Glenn Morris <rgm@gnu.org>
3062 * nsterm.m (ns_init_paths): Don't mess with INFOPATH. (Bug#2791)
3064 2012-05-26 Eli Zaretskii <eliz@gnu.org>

3067 * xdisp.c (draw_row_with_mouse_face):
3068 Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
3070 * w32console.c: Include window.h.
3071 (w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
3072 New functions.
3073 (initialize_w32_display): Initialize mouse-highlight data.
3075 * w32inevt.c: Include termchar.h and window.h.
3076 (do_mouse_event): Support mouse-autoselect-window. When the mouse
3077 moves, call note_mouse_highlight. If help_echo changed, call
3078 gen_help_event to produce help-echo message in the echo area.
3079 Call clear_mouse_face if mouse_face_hidden is set in the mouse
3080 highlight info.
3082 2012-05-26 Paul Eggert <eggert@cs.ucla.edu>
3084 * lread.c (read1): Simplify slightly to avoid an overflow warning
3085 with GCC 4.7.0 on x86-64.
3087 2012-05-26 Eli Zaretskii <eliz@gnu.org>
3089 * bidi.c (bidi_mirror_char): Revert last change: an int is
3090 definitely wide enough here.
3092 2012-05-25 Paul Eggert <eggert@cs.ucla.edu>
3094 Fix integer width and related bugs (Bug#9874).

3101 (allocate_vectorlike, Fmake_vector, find_string_data_in_pure)
3102 (make_pure_string, make_pure_c_string, make_pure_vector, Fpurecopy)
3103 (mark_vectorlike):
3104 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3105 (allocate_pseudovector):
3106 Use int, not EMACS_INT, where int is wide enough.
3107 (inhibit_garbage_collection, Fgarbage_collect):
3108 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3109 * bidi.c (bidi_mirror_char): Use EMACS_INT, not int, where
3110 int might not be wide enough.
3111 (bidi_cache_search, bidi_cache_find, bidi_init_it)

3113 (bidi_at_paragraph_end, bidi_find_paragraph_start)
3114 (bidi_paragraph_init, bidi_resolve_explicit, bidi_resolve_weak)
3115 (bidi_level_of_next_char, bidi_move_to_visually_next):
3116 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3117 * buffer.c (copy_overlays, Fgenerate_new_buffer_name)
3118 (Fkill_buffer, Fset_buffer_major_mode)

3121 (overlay_touches_p, struct sortvec, record_overlay_string)
3122 (overlay_strings, recenter_overlay_lists)
3123 (adjust_overlays_for_insert, adjust_overlays_for_delete)
3124 (fix_start_end_in_overlays, fix_overlays_before, modify_overlay)
3125 (Fmove_overlay, Fnext_overlay_change, Fprevious_overlay_change)
3126 (Foverlay_recenter, last_overlay_modification_hooks_used)
3127 (report_overlay_modification, evaporate_overlays, enlarge_buffer_text):
3128 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3129 (validate_region): Omit unnecessary test for b <= e,
3130 since that's guaranteed by the previous test.
3131 (adjust_overlays_for_delete): Avoid pos + length overflow.
3132 (Fmove_overlay, Fdelete_overlay, add_overlay_mod_hooklist)
3133 (report_overlay_modification):
3134 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3135 (Foverlays_at, Fnext_overlay_change, Fprevious_overlay_change):
3136 Omit pointer cast, which isn't needed anyway, and doesn't work
3137 after the EMACS_INT -> ptrdiff_t change.
3138 (Fmove_overlay): Clip BEG and END to ptrdiff_t to avoid overflow.
3139 * buffer.h: Adjust decls to match defn changes elsewhere.
3140 (struct buffer_text, struct buffer):
3141 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3142 Use EMACS_INT, not int, where int might not be wide enough.
3143 * bytecode.c (unmark_byte_stack, exec_byte_code): Use ptrdiff_t,
3144 not int, to avoid needless 32-bit limit on 64-bit hosts.
3145 (exec_byte_code): Use tighter memory-full test, one that checks
3146 for alloca overflow. Don't compute the address of the object just
3147 before an array, as that's not portable. Use EMACS_INT, not
3148 ptrdiff_t or int, where ptrdiff_t or int might not be wide enough.
3149 * callint.c (Fcall_interactively):
3150 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3151 * callproc.c (call_process_kill, Fcall_process):
3152 Don't assume pid_t fits into an Emacs fixnum.
3153 (call_process_cleanup, Fcall_process, child_setup):

3162 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3163 (casify_object): Avoid integer overflow when overallocating buffer.
3164 * casetab.c (set_identity, shuffle): Prefer int to unsigned when
3165 either works. Use lint_assume to convince GCC 4.6.1 that it's OK.
3166 * category.c (Fchar_category_set): Don't assume fixnum fits in int.
3167 * category.h (CATEGORYP): Don't assume arg is nonnegative.
3168 * ccl.c (GET_CCL_INT): Remove; no longer needed, since the
3169 integers are now checked earlier. All uses replaced with XINT.
3170 (ccl_driver):
3171 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3172 For CCL_MapSingle, check that content and value are in int range.

3174 Check that Vcode_version_map_vector is a vector.
3175 (resolve_symbol_ccl_program): Check that vector header is in range.
3176 Always copy the vector, so that we can check its contents reliably
3177 now rather than having to recheck each instruction as it's being
3178 executed. Check that vector words fit in 'int'.
3179 (ccl_get_compiled_code, Fregister_ccl_program)
3180 (Fregister_code_conversion_map): Use ptrdiff_t, not int, for
3181 program indexes, to avoid needless 32-bit limit on 64-bit hosts.
3182 (Fccl_execute, Fccl_execute_on_string): Check that initial reg
3183 contents are in range.
3184 (Fccl_execute_on_string): Check that status is in range.
3185 * ccl.h (struct ccl_program.idx): Now ptrdiff_t, not int.
3186 * character.c (char_resolve_modifier_mask, Fchar_resolve_modifiers):
3187 Accept and return EMACS_INT, not int, because callers can pass values

3194 Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
3195 (Funibyte_string): Use CHECK_RANGED_INTEGER, not CHECK_NATNUM, to
3196 avoid mishandling large integers.

3875 * xselect.c (TRACE1): Don't assume pid_t promotes to int.
3876 (x_get_local_selection, x_reply_selection_request)
3877 (x_handle_selection_request, wait_for_property_change):
3878 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3879 (selection_data_to_lisp_data): Use short, not EMACS_INT, where
3880 short is wide enough.
3881 (x_send_client_event): Don't assume fixnum fits in int.
3882 * xterm.c (x_x_to_emacs_modifiers):
3883 Don't assume EMACS_INT overflows nicely into int.
3884 (x_emacs_to_x_modifiers): Use EMACS_INT, not int, because values
3885 may come from Lisp.
3886 (handle_one_xevent): NATNUMP can eval its arg twice.
3887 (x_connection_closed):
3888 Use ptrdiff_t, not int, to avoid needless 32-bit limit on 64-bit hosts.
3889 * xterm.h: Adjust decls to match defn changes elsewhere.
3890 (struct scroll_bar): Use struct vectorlike_header
3891 rather than rolling our own approximation.
3892 (SCROLL_BAR_VEC_SIZE): Remove; not used.
3894 2012-05-25 Glenn Morris <rgm@gnu.org>
3896 * lisp.mk (lisp): Update for more files being compiled now.
3898 2012-05-25 Stefan Monnier <monnier@iro.umontreal.ca>
3900 * lread.c: Remove `read_pure' which makes no difference.
3901 (read_pure): Remove var.
3902 (unreadpure): Remove function.
3903 (readevalloop): Don't call read_list with -1 flag.
3904 (read1, read_vector): Don't test read_pure any more.
3905 (read_list): Simplify.
3907 * fileio.c, character.h: Minor style tweaks.
3909 2012-05-24 Dmitry Antipov <dmantipov@yandex.ru>
3911 * window.h (clip_changed): Remove useless declaration.
3913 2012-05-22 Juanma Barranquero <lekktu@gmail.com>
3915 * makefile.w32-in: Follow-up to revno:108341.
3916 (TAGS, TAGS-gmake, CONFIG_H): Remove further references to m/intel386.h.
3918 2012-05-22 Paul Eggert <eggert@cs.ucla.edu>
3920 Remove src/m/*.
3921 This directory predates autoconf and is no longer needed nowadays.
3922 Move its few remaining bits of functionality to where they're needed.
3923 * m/README, m/alpha.h, m/amdx86-64.h, m/ia64.h, m/ibmrs6000.h:
3924 * m/ibms390x.h, m/intel386.h, m/m68k.h, m/macppc.h, m/sparc.h:
3925 * m/template.h: Remove.
3926 * Makefile.in (M_FILE): Remove. All uses removed.
3927 * alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS):
3928 * lisp.h (USE_LSB_TAG):
3929 * mem-limits.h (EXCEEDS_LISP_PTR):
3930 Use VAL_MAX, not VALBITS, in #if.
3931 * lisp.h (EMACS_INT_MAX): New macro, useful in #if.
3932 (EMACS_UINT): Define unconditionally now.
3933 (BITS_PER_CHAR, BITS_PER_SHORT, BITS_PER_INT, BITS_PER_LONG)
3934 (BITS_PER_EMACS_INT): New constants, replacing
3935 what used to be in config.h, but not useful in #if.
3936 (GCTYPEBITS, VALBITS): Define unconditionally, since m/* files don't
3937 define them any more.
3938 (VAL_MAX): New macro.
3939 (VALMASK): Use it.
3940 * puresize.h (PURESIZE_RATIO): Use EMACS_INT_MAX, not
3941 BITS_PER_EMACS_INT, in #if.
3942 * s/aix4-2.h (BROKEN_FIONREAD, BROKEN_SIGAIO, BROKEN_SIGPTY)
3943 (BROKEN_SIGPOLL): Move here from m/ibmrs6000.h, which was removed.
3944 * s/gnu-linux.h (ULIMIT_BREAK_VALUE) [__i386__]:
3945 * s/ms-w32.h (DATA_START):
3946 Move here from removed file m/intel386.h.
3947 * s/gnu.h (NLIST_STRUCT): Remove undef; 'configure' does this.
3948 * s/irix6-5.h (_LP64): Remove; lisp.h no longer needs this.
3950 2012-05-21 Paul Eggert <eggert@cs.ucla.edu>
3952 Assume C89 or later.
3953 * alloc.c, buffer.c, lisp.h: Replace POINTER_TYPE with void.
3954 * alloc.c (overrun_check_malloc, overrun_check_realloc, xmalloc)
3955 (xrealloc):
3956 * buffer.c (mmap_free_1, mmap_enlarge): Omit needless casts.
3957 * editfns.c, fns.c, gmalloc.c, insdel.c, sysdep.c, termcap.c (NULL):
3958 * textprop.c, tparam.c (NULL): Remove.
3959 * ralloc.c, vm-limit.c (POINTER): Assume void * works.
3960 * regex.c (SIGN_EXTEND_CHAR): Assume signed char works.
3961 * regex.h (_RE_ARGS): Remove. All uses rewritten to use prototypes.
3962 * unexelf.c (ElfBitsW): Assume c89 preprocessor or better.
3963 * xterm.c (input_signal_count): Assume volatile works.
3965 2012-05-21 Ken Brown <kbrown@cornell.edu>
3967 * xgselect.c (xg_select): Fix first argument in call to 'select'
3968 (bug#11508).
3970 2012-05-20 Ken Brown <kbrown@cornell.edu>
3972 * gmalloc.c (_free_internal_nolock, _realloc_internal_nolock)
3973 [CYGWIN]: Cast ptr to (char *) before comparing to _heapbase.
3975 2012-05-19 Ken Brown <kbrown@cornell.edu>
3977 * xfns.c (x_in_use): Remove `static' qualifier.
3978 * xterm.h (x_in_use): Declare.
3979 * xgselect.c: Include xterm.h.
3980 (xg_select): Test `x_in_use' instead of `inhibit_window_system'
3981 and `display_arg' (bug#9754).
3983 2012-05-19 Paul Eggert <eggert@cs.ucla.edu>
3985 * s/ms-w32.h (HAVE_GETDOMAINNAME): Remove; not needed.
3987 * m/vax.h: Remove; no longer needed since HAVE_FTIME is being removed.
3988 * s/ms-w32.h (HAVE_FTIME): Remove; not needed.
3990 2012-05-18 Eli Zaretskii <eliz@gnu.org>
3992 Fix compilation with -DGLYPH_DEBUG=1 on MS-Windows.
3994 * w32term.c [GLYPH_DEBUG]: Add prototype for x_check_font.
3995 (x_check_font) [GLYPH_DEBUG]: New function, copied from xterm.c.
3997 * w32fns.c (unwind_create_frame) [GLYPH_DEBUG]: Fix broken
3998 reference to image_cache->refcount.
3999 (x_create_tip_frame): Fix broken use of FRAME_IMAGE_CACHE.
4001 2012-05-17 Juri Linkov <juri@jurta.org>
4003 * search.c (Fword_search_regexp, Fword_search_backward)
4004 (Fword_search_forward, Fword_search_backward_lax)
4005 (Fword_search_forward_lax): Move functions to isearch.el
4006 (bug#10145, bug#11381).
4008 2012-05-16 Paul Eggert <eggert@cs.ucla.edu>
4010 * xgselect.c (xg_select): Just invoke 'select' if -nw (Bug#9754).
4012 2012-05-15 Stefan Monnier <monnier@iro.umontreal.ca>
4014 * lread.c (init_obarray): Declare Qt and Qnil as special.
4016 2012-05-14 Glenn Morris <rgm@gnu.org>
4018 * nsterm.m (ns_init_paths): Fix typo ("libexec" not "lib-exec").
4019 Put "libexec" before "bin", for the sake of init_callproc_1.
4021 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
4023 * keyboard.c (kbd_buffer_get_event) [!HAVE_DBUS]: Omit unused local.
4025 * unexaix.c: Port to more-recent AIX compilers.
4026 (report_error, report_error_1, make_hdr, copy_sym)
4027 (mark_x, adjust_lnnoptrs, unrelocate_symbols):
4028 Make arguments const char *, not char *, to avoid violations of C
4029 standard and to fix some AIX warnings reported by Gilles Pion.
4031 2012-05-14 Eli Zaretskii <eliz@gnu.org>
4033 * xdisp.c (handle_stop): Don't call get_overlay_strings_1 if we
4034 already have overlays loaded.
4035 (handle_single_display_spec): Before returning without displaying
4036 fringe bitmap, synchronize the bidi iterator with the main display
4037 iterator, by calling iterate_out_of_display_property.
4038 (iterate_out_of_display_property): Detect buffer iteration by
4039 testing that it->string is a Lisp string.
4040 (get_next_display_element): When the current object is exhausted,
4041 and there's something on it->stack, call set_iterator_to_next to
4042 proceed with what's on the stack, instead of returning zero.
4043 (set_iterator_to_next): If called at the end of a Lisp string,
4044 proceed to consider_string_end without incrementing string
4045 position. Don't increment display vector index past the end of
4046 the display vector. (Bug#11417)
4047 (pos_visible_p): Don't report a position visible when move_it_to
4048 stopped at the last line of window, which happens to be scanned
4049 backwards by the bidi iteration. (Bug#11464)
4051 2012-05-14 Eli Zaretskii <eliz@gnu.org>
4053 * xdisp.c (handle_single_display_spec): Return 1 for left-margin
4054 and right-margin display specs even if the spec is invalid or we
4055 are on a TTY, and thus unable to display on the fringes.
4056 That's because the text with the property will not be displayed anyway,
4057 so we need to signal to the caller that this is a "replacing"
4058 display spec. This fixes display when the spec is invalid or we
4059 are on a TTY.
4061 2012-05-14 Paul Eggert <eggert@cs.ucla.edu>
4063 * unexaix.c (make_hdr): Fix typo in prototype.
4064 This bug broke the build on AIX. Problem reported by Gilles Pion.
4066 2012-05-14 Michael Albinus <michael.albinus@gmx.de>
4068 * keyboard.c (kbd_buffer_get_event): Read special events also in
4069 batch mode. (Bug#11415)
4071 2012-05-12 Glenn Morris <rgm@gnu.org>
4073 * ns.mk: Update for ns_appbindir no longer having trailing "/".
4075 2012-05-12 Eli Zaretskii <eliz@gnu.org>
4077 * lisp.mk (lisp): Add newcomment.elc.
4079 2012-05-12 Glenn Morris <rgm@gnu.org>
4081 * Makefile.in (MKDIR_P): New, set by configure.
4082 * ns.mk (${ns_appdir}, ${ns_appbindir}Emacs): Use $MKDIR_P.
4084 2012-05-11 Paul Eggert <eggert@cs.ucla.edu>
4086 Remove unused function hourglass_started.
4087 * dispextern.h (hourglass_started):
4088 * w32fns.c (hourglass_started):
4089 * xdisp.c (hourglass_started): Remove.
4091 2012-05-10 Juanma Barranquero <lekktu@gmail.com>
4093 * makefile.w32-in ($(BLD)/gmalloc.$(O), $(BLD)/w32menu.$(O)):
4094 Update dependencies.
4096 2012-05-10 Paul Eggert <eggert@cs.ucla.edu>
4098 * xgselect.c (xg_select): Put maxfds+1 into a var.
4099 This is slightly clearer, and pacifies Ubuntu 12.04 gcc.
4101 * sound.c (DEFAULT_ALSA_SOUND_DEVICE): Define only if HAVE_ALSA.
4103 2012-05-10 Dave Abrahams <dave@boostpro.com>
4105 * filelock.c (syms_of_filelock): New boolean create-lockfiles.
4106 (lock_file): If create_lockfiles is 0, do nothing. (Bug#11227)
4108 2012-05-09 Michael Albinus <michael.albinus@gmx.de>
4110 * dbusbind.c (xd_registered_buses): New internal Lisp object.
4111 Rename all occurences of Vdbus_registered_buses to xd_registered_buses.
4112 (syms_of_dbusbind): Remove declaration of Vdbus_registered_buses.
4113 Initialize xd_registered_buses.
4115 2012-05-09 Paul Eggert <eggert@cs.ucla.edu>
4117 Untag more efficiently if USE_LSB_TAG.
4118 This is based on a proposal by YAMAMOTO Mitsuharu in
4119 <http://lists.gnu.org/archive/html/emacs-devel/2008-01/msg01876.html>.
4120 For an admittedly artificial (nth 8000 longlist) benchmark on
4121 Fedora 15 x86-64, this yields a 25% CPU speedup. Also, it shrinks
4122 Emacs's overall text size by 1%.
4123 * lisp.h (XUNTAG): New macro.
4124 (XCONS, XVECTOR, XSTRING, XSYMBOL, XFLOAT, XMISC, XPROCESS, XWINDOW)
4125 (XTERMINAL, XSUBR, XBUFFER, XCHAR_TABLE, XSUB_CHAR_TABLE, XBOOL_VECTOR)
4126 (XSETTYPED_PSEUDOVECTOR, XHASH_TABLE, TYPED_PSEUDOVECTORP): Use it.
4127 * eval.c (Fautoload):
4128 * font.h (XFONT_SPEC, XFONT_ENTITY, XFONT_OBJECT):
4129 * frame.h (XFRAME): Use XUNTAG.
4131 Port recent dbusbind.c changes to 32-bit --with-wide-int.
4132 * dbusbind.c (xd_append_arg, xd_retrieve_arg, Fdbus_message_internal):
4133 Remove unportable assumptions about print widths of types like
4134 dbus_uint32_t.
4135 (xd_get_connection_address, Fdbus_init_bus): Cast Emacs integer to
4136 intptr_t when converting between pointer and integer, to avoid GCC
4137 warnings about wrong width.
4139 2012-05-09 Eli Zaretskii <eliz@gnu.org>
4141 * w32proc.c (new_child): Force Windows to reserve only 64KB of
4142 stack for each reader_thread, instead of defaulting to 8MB
4143 determined by the linker. This avoids failures in creating
4144 subprocesses on Windows 7, see the discussion in this thread:
4145 http://lists.gnu.org/archive/html/emacs-devel/2012-03/msg00119.html.
4147 2012-05-07 Jérémy Compostella <jeremy.compostella@gmail.com>
4149 Fix up display of the *Minibuf-0* buffer in the mini window.
4150 * keyboard.c (read_char): Don't clear the echo area if there's no
4151 message to clear.
4152 * xdisp.c (redisplay_internal): Redisplay the mini window (with the
4153 contents of *Minibuf-0*) if there's no message displayed in its stead.
4155 2012-05-07 Michael Albinus <michael.albinus@gmx.de>
4157 * dbusbind.c (XD_DEBUG_MESSAGE): Don't print message twice in
4158 batch mode.
4160 2012-05-06 Chong Yidong <cyd@gnu.org>
4162 * lisp.mk (lisp): Update.
4164 2012-05-05 Jim Meyering <meyering@redhat.com>
4166 * w32font.c (fill_in_logfont): NUL-terminate a string (Bug#11372).
4168 2012-05-04 Stefan Monnier <monnier@iro.umontreal.ca>
4170 * data.c (PUT_ERROR): New macro.
4171 (syms_of_data): Use it. Add new error type `user-error'.
4172 * undo.c (user_error): New function.
4173 (Fprimitive_undo): Use it.
4174 * print.c (print_error_message): Adjust print style for `user-error'.
4175 * keyboard.c (user_error): New function.
4176 (Fexit_recursive_edit, Fabort_recursive_edit): Use it.
4178 2012-05-03 Paul Eggert <eggert@cs.ucla.edu>
4180 Do not limit current-time-string to years 1000..9999.
4181 * editfns.c (TM_YEAR_IN_ASCTIME_RANGE): Remove.
4182 (Fcurrent_time_string): Support any year that is supported by the
4183 underlying localtime representation. Don't use asctime, as it
4184 has undefined behavior for years outside the range -999..9999.
4186 2012-05-02 Paul Eggert <eggert@cs.ucla.edu>
4188 Fix race conditions involving setenv, gmtime, localtime, asctime.
4189 Without this fix, interrupts could mess up code that uses these
4190 nonreentrant functions, since setting TZ invalidates existing
4191 tm_zone or tzname values, and since most of these functions return
4192 pointers to static storage.
4193 * editfns.c (format_time_string, Fdecode_time, Fencode_time)
4194 (Fcurrent_time_string, Fcurrent_time_zone, Fset_time_zone_rule):
4195 Grow the critical sections to include not just invoking
4196 localtime/gmtime, but also accessing these functions' results
4197 including their tm_zone values if any, and any related TZ setting.
4198 (format_time_string): Last arg is now struct tm *, not struct tm **,
4199 so that the struct tm is saved in the critical section.
4200 All callers changed. Simplify allocation of initial buffer, partly
4201 motivated by the fact that memory allocation needs to be outside
4202 the critical section.
4204 2012-05-02 Dmitry Antipov <dmantipov@yandex.ru>
4206 * intervals.c (adjust_intervals_for_insertion): Initialize `newi'
4207 with RESET_INTERVAL.
4209 * buffer.c (Fget_buffer_create, Fmake_indirect_buffer):
4210 Remove duplicated buffer name initialization.
4212 2012-05-02 Jim Meyering <jim@meyering.net>
4214 * xterm.c (x_term_init): Use memcpy instead of strncpy (Bug#11373).
4216 * xfns.c (x_window): Use xstrdup (Bug#11375).
4218 2012-05-02 Eli Zaretskii <eliz@gnu.org>
4220 * xdisp.c (pos_visible_p): If already at a newline from the
4221 display string before the 'while' loop, don't walk back the glyphs
4222 from it3.glyph_row. Solves assertion violation when the display
4223 string begins with a newline (egg.el). (Bug#11367)
4225 2012-05-01 Stefan Monnier <monnier@iro.umontreal.ca>
4227 * keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
4228 Move to simple.el.
4230 2012-05-01 Glenn Morris <rgm@gnu.org>
4232 * syssignal.h: Remove reference to BROKEN_SIGINFO (last used in
4233 s/ptx4.h), BROKEN_SIGTSTP (last used in m/ustation.h, m/dpx2.h),
4234 and BROKEN_SIGURG (was in s/gnu-linux.h prior to 2008-02-10).
4235 All were removed before 23.1.
4237 * dispnew.c: Remove HAVE_LIBNCURSES test;
4238 it is always true on relevant platforms.
4240 * Makefile.in (LD_SWITCH_X_SITE_RPATH):
4241 Rename from LD_SWITCH_X_SITE_AUX_RPATH.
4243 * Makefile.in (LD_SWITCH_X_SITE_AUX): Remove; no longer used.
4245 2012-04-30 Andreas Schwab <schwab@linux-m68k.org>
4247 * .gdbinit (xpr): Remove checks for no longer existing misc types.
4248 (xintfwd, xboolfwd, xobjfwd, xbufobjfwd, xkbobjfwd, xbuflocal):
4249 Remove.
4251 2012-04-28 Paul Eggert <eggert@cs.ucla.edu>
4253 Do not avoid creating empty evaporating overlays (Bug#9642).
4254 * buffer.c (Fmove_overlay): Revert the change of 2012-04-23.
4255 That is, do not delete an evaporating overlay if it becomes
4256 empty after its bounds are adjusted to fit within its buffer.
4257 This fix caused other problems, and I'm reverting it until we get
4258 to the bottom of them.
4260 2012-04-27 Chong Yidong <cyd@gnu.org>
4262 * xselect.c (x_convert_selection): Initialize a pointer (Bug#11315).
4264 2012-04-27 Eli Zaretskii <eliz@gnu.org>
4266 * xdisp.c (pos_visible_p): If the window start position is beyond
4267 ZV, start the display from buffer beginning. Prevents assertion
4268 violation in init_iterator when the minibuffer window is scrolled
4269 via the scroll bar.
4271 * window.c (window_scroll_pixel_based): Likewise.
4273 2012-04-27 Chong Yidong <cyd@gnu.org>
4275 * keymap.c (where_is_internal): Doc fix (Bug#10872).
4277 2012-04-27 Glenn Morris <rgm@gnu.org>
4279 * fileio.c (Fcopy_file, Fset_file_selinux_context):
4280 Ignore ENOTSUP failures from setfilecon functions. (Bug#11245)
4282 2012-04-27 Eli Zaretskii <eliz@gnu.org>
4284 * dispnew.c (swap_glyph_pointers, copy_row_except_pointers):
4285 Don't overrun array limits of glyph row's used[] array. (Bug#11288)
4287 2012-04-26 Eli Zaretskii <eliz@gnu.org>
4289 * xdisp.c (IT_DISPLAYING_WHITESPACE): In addition to the loaded
4290 display element, check also the underlying string or buffer
4291 character. (Bug#11341)
4293 * w32menu.c: Include w32heap.h.
4294 (add_menu_item): If the call to AppendMenuW (via
4295 unicode_append_menu) fails, disable Unicode menus only if we are
4296 running on Windows 9X/Me.
4298 2012-04-24 Andreas Schwab <schwab@linux-m68k.org>
4300 * .gdbinit (xpr): Handle USE_2_TAGS_FOR_INTS.
4301 (xgetint): Add missing shift for LSB tags.
4303 2012-04-24 Martin Rudalics <rudalics@gmx.at>
4305 * keyboard.c (read_char): Don't wipe echo area for select window
4306 events: These might get delayed via `mouse-autoselect-window'
4307 (Bug#11304).
4309 2012-04-24 Juanma Barranquero <lekktu@gmail.com>
4311 * gnutls.c (init_gnutls_functions): Protect against (unlikely)
4312 manipulation of :loaded-from data.
4314 2012-04-23 Juanma Barranquero <lekktu@gmail.com>
4316 * gnutls.c (init_gnutls_functions): The value of :loaded-from is
4317 now a cons (bug#11311).
4319 2012-04-23 Paul Eggert <eggert@cs.ucla.edu>
4321 Do not create empty overlays with the evaporate property (Bug#9642).
4322 * buffer.c (Fmove_overlay): Delete an evaporating overlay
4323 if it becomes empty after its bounds are adjusted to fit within
4324 its buffer. Without this fix, in a nonempty buffer (let ((o
4325 (make-overlay 1 2))) (overlay-put o 'evaporate t) (move-overlay o 0 1))

4470 2012-04-20 Chong Yidong <cyd@gnu.org>
4472 * process.c (wait_reading_process_output): If EIO occurs on a pty,

4528 New extern decls, to avoid calling undeclared functions.
4529 (dont_register_blocks): Define if ((!SYSTEM_MALLOC && !SYNC_INPUT)
4530 && GC_MALLOC_CHECK), not if ((GC_MARK_STACK || defined
4531 GC_MALLOC_CHECK) && GC_MALLOC_CHECK), to match when it's used.

4548 * m/ia64.h (r_alloc, r_alloc_free) [REL_ALLOC && !_MALLOC_INTERNAL]:
4549 Remove decls. This fixes an "It stinks!".

4553 2012-04-15 Andreas Schwab <schwab@linux-m68k.org>
4555 * lisp.h (struct Lisp_Symbol): Remove explicit padding.

4572 Remove definition of GC_MARK_STACK, since the default now works.
4573 * s/aix4-2.h, s/hpux10-20.h, s/unixware.h:
4574 Define GC_MARK_STACK to GC_USE_GCPROS_AS_BEFORE, since that's
4575 no longer the default.
4576 * s/gnu-linux.h (GC_MARK_STACK): Adjust to change in default.
4578 2012-04-14 Atsuo Ohki <ohki@gssm.otsuka.tsukuba.ac.jp> (tiny change)

4601 2012-04-11 Daniel Colascione <dancol@dancol.org>
4603 * s/cygwin.h: The vfork the #define in cygwin.h was protecting
4604 against is gone. It's better to use vfork now so that when Cygwin
4605 gains a new, working vfork, we use it automatically (bug#10398).
4607 2012-04-11 Stefan Monnier <monnier@iro.umontreal.ca>

4662 2012-04-09 Eli Zaretskii <eliz@gnu.org>
4664 * xdisp.c (set_cursor_from_row): If the display string appears in
4665 the buffer at position that is closer to point than the position
4666 after the display string, display the cursor on the first glyph of
4667 the display string. Fixes cursor display when a 'display' text
4668 property immediately follows invisible text. (Bug#11094)
4670 2012-04-09 Paul Eggert <eggert@cs.ucla.edu>
4672 composite.c: use 'double' consistently
4673 * composite.c (get_composition_id): Use 'double' consistently
4674 instead of converting 'float' to 'double' and vice versa; this is
4675 easier to understand and avoids a GCC warning.
4677 2012-04-09 Glenn Morris <rgm@gnu.org>
4679 * Makefile.in: Generate leim-list with bootstrap-emacs, in

4724 [!WINDOWSNT]: New macros.
4725 (init_libxml2_functions, libxml2_loaded_p): New functions.
4726 (parse_region): Call fn_xmlCheckVersion instead of using the macro
4727 LIBXML_TEST_VERSION. Call libxml2 functions via the fn_* macros.
4728 (xml_cleanup_parser): New function, export for fn_xmlCleanupParser.
4729 Calls xmlCleanupParser only if libxml2 was loaded (or statically
4730 linked in).

4732 Call init_libxml2_functions before calling libxml2 functions.
4733 (syms_of_xml) <Qlibxml2_dll>: DEFSYM it.
4735 * emacs.c: Don't include libxml/parser.h.

4745 move_it_to point. (Bug#11133)
4747 2012-04-06 Eli Zaretskii <eliz@gnu.org>
4749 * buffer.h (FETCH_CHAR, FETCH_MULTIBYTE_CHAR):
4750 * character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
4751 about subtle differences between FETCH_CHAR* and STRING_CHAR*
4752 macros related to unification of CJK characters. For the details,
4753 see the discussion following the message here:
4754 http://debbugs.gnu.org/cgi/bugreport.cgi?bug=11073#14.
4756 2012-04-04 Chong Yidong <cyd@gnu.org>

4770 2012-03-31 Eli Zaretskii <eliz@gnu.org>
4772 * xdisp.c (move_it_by_lines): When DVPOS is positive, and the
4773 position we get to after a call to move_it_to fails the
4774 IS_POS_VALID_AFTER_MOVE_P test, move to the next buffer position
4775 only if we wind up in a string from display property. (Bug#11063)
4777 * window.c (Fdelete_other_windows_internal): Invalidate the row
4778 and column information about mouse highlight, so that redisplay
4779 restores it after reallocating the glyph matrices. (Bug#7464)
4781 * xdisp.c (set_cursor_from_row): If `cursor' property on a display
4782 string comes from a `display' text property, use the buffer
4783 position of that property as if we actually saw that position in
4784 the row's glyphs.
4785 (move_it_by_lines): Remove the assertion that
4786 "it->current_x == 0 && it->hpos == 0" which can be legitimately
4787 violated when there's a before-string at the beginning of a line.
4788 (Bug#11063)
4790 2012-03-30 Eli Zaretskii <eliz@gnu.org>
4792 * xdisp.c (append_space_for_newline): If the default face was
4793 remapped, use the remapped face for the appended newline.
4794 (extend_face_to_end_of_line): Use the remapped default face for
4795 extending the face to the end of the line.
4796 (display_line): Call extend_face_to_end_of_line when the default
4797 face was remapped. (Bug#11068)
4799 2012-03-29 Eli Zaretskii <eliz@gnu.org>
4801 * s/ms-w32.h: Discourage from defining HAVE_GETCWD.
4803 2012-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
4805 * keyboard.c (safe_run_hooks_error): Don't unquote strings.
4807 2012-03-27 Glenn Morris <rgm@gnu.org>
4809 * search.c (Fword_search_backward_lax, Fword_search_forward_lax):
4810 Doc fixes.
4812 2012-03-26 Kenichi Handa <handa@m17n.org>
4814 * dispextern.h (struct glyph): Fix previous change. Change the
4815 bit length of glyphless.ch to 25 (Bug#11082).
4817 2012-03-26 Chong Yidong <cyd@gnu.org>
4819 * keyboard.c (Vselection_inhibit_update_commands): New variable.
4820 (command_loop_1): Use it; inhibit selection update for
4821 handle-select-window too (Bug#8996).
4823 2012-03-25 Fabrice Popineau <fabrice.popineau@supelec.fr>
4825 * w32heap.c (_heap_init, _heap_term): Remove dead MSVC-specific code.
4827 2012-03-25 Kenichi Handa <handa@m17n.org>
4829 * dispextern.h (struct glyph): Change the bit length of
4830 glyphless.ch to 22 to make the member glyphless fit in 32 bits.
4832 2012-03-24 Eli Zaretskii <eliz@gnu.org>
4834 * s/ms-w32.h (tzname): Include time.h before redirecting to
4835 _tzname. Fixes the MSVC build. (Bug#9960)
4837 2012-03-24 Andreas Schwab <schwab@linux-m68k.org>
4839 * xdisp.c (produce_glyphless_glyph): Limit length of acronym to 6
4840 characters.
4842 * xterm.c (XTread_socket): Only modify handling_signal if
4843 !SYNC_INPUT. (Bug#11080)
4845 2012-03-23 Eli Zaretskii <eliz@gnu.org>
4847 * bidi.c (bidi_fetch_char): Use STRING_CHAR_AND_LENGTH instead of
4848 FETCH_MULTIBYTE_CHAR followed by CHAR_BYTES. Prevents crashes
4849 when fetching a multibyte character consumes more bytes than
4850 CHAR_BYTES returns, due to unification of CJK characters in
4851 string_char. (Bug#11073)
4853 2012-03-23 Troels Nielsen <bn.troels@gmail.com> (tiny change)
4855 * process.c (wait_reading_process_output): Handle pty disconnect
4856 by refraining from sending oneself a SIGCHLD (bug#10933).
4858 2012-03-22 Chong Yidong <cyd@gnu.org>
4860 * dispextern.h (struct it): New member string_from_prefix_prop_p.
4862 * xdisp.c (push_prefix_prop): Rename from push_display_prop.
4863 Mark string as coming from a prefix property.
4864 (handle_face_prop): Use default face for prefix strings (Bug#4281).
4865 (pop_it, reseat_1): Save and restore string_from_prefix_prop_p.
4867 2012-03-21 Chong Yidong <cyd@gnu.org>
4869 * xfaces.c (Vface_remapping_alist): Doc fix.
4871 2012-03-20 Eli Zaretskii <eliz@gnu.org>
4873 * w32proc.c (Fw32_set_console_codepage)
4874 (Fw32_set_console_output_codepage, Fw32_get_codepage_charset):
4875 Doc fixes.
4877 2012-03-20 Chong Yidong <cyd@gnu.org>
4879 * dispnew.c (Fredisplay, Vredisplay_preemption_period): Update doc
4880 to reflect default non-nil value of redisplay-dont-pause.
4882 2012-03-19 Kenichi Handa <handa@m17n.org>
4884 * ftfont.c (ftfont_drive_otf): Mask bits of character code to make
4885 it fit in a valid range (Bug#11003).
4887 2012-03-18 Eli Zaretskii <eliz@gnu.org>
4889 * xdisp.c (cursor_row_p): Even if the glyph row ends in a string
4890 that is not from display property, accept the row as a "cursor
4891 row" if one of the string's character has a non-nil `cursor'
4892 property. Fixes cursor positioning when there are newlines in
4893 overlay strings, e.g. in icomplete.el. (Bug#11035)
4895 2012-03-12 Paul Eggert <eggert@cs.ucla.edu>
4897 * buffer.c (compare_overlays): Don't assume args differ (Bug#6830).
4899 2012-03-12 Chong Yidong <cyd@gnu.org>
4901 * eval.c (inhibit_lisp_code): Rename from
4902 inhibit_window_configuration_change_hook; move from window.c.
4904 * xfns.c (unwind_create_frame_1, Fx_create_frame):
4905 * window.c (run_window_configuration_change_hook)
4906 (syms_of_window): Callers changed.
4908 2012-03-11 Chong Yidong <cyd@gnu.org>

4916 * frame.c (other_visible_frames): Don't assume the selected frame
4917 is visible (Bug#10955).
4919 2012-03-09 Stefan Monnier <monnier@iro.umontreal.ca>
4921 * buffer.c (compare_overlays): Avoid qsort's instability (bug#6830).
4923 2012-03-08 Jan Djärv <jan.h.d@swipnet.se>
4925 * gtkutil.c (x_wm_set_size_hint): Use one row in call to
4926 FRAME_TEXT_LINES_TO_PIXEL_HEIGHT so base_height is greater than
4927 zero (Bug#10954).
4929 2012-03-03 Glenn Morris <rgm@gnu.org>
4931 * alloc.c (Fgarbage_collect, misc-objects-consed): Doc fixes.
4933 2012-03-02 Eli Zaretskii <eliz@gnu.org>
4935 * xdisp.c (try_window_reusing_current_matrix): Don't move cursor
4936 position past the first glyph_row that ends at ZV. (Bug#10902)
4937 (redisplay_window, next_element_from_string): Fix typos in
4938 comments.
4939 (redisplay_window): Pass to move_it_vertically the margin in
4940 pixels, not in screen lines.
4942 2012-03-02 Glenn Morris <rgm@gnu.org>
4944 * buffer.c (buffer-list-update-hook): Doc fix.
4946 2012-02-29 Eli Zaretskii <eliz@gnu.org>
4948 * xdisp.c (get_overlay_strings_1): Under bidi redisplay, call
4949 push_it before setting up the iterator for the first overlay
4950 string, even if we have an empty string loaded.
4951 (next_overlay_string): If there's an empty string on the iterator
4952 stack, pop the stack. (Bug#10903)
4954 2012-02-25 Paul Eggert <eggert@cs.ucla.edu>
4956 Generalize fix for crash due to non-contiguous EMACS_INT (Bug#10780).
4957 Suggested by Stefan Monnier in
4958 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00692.html>.
4959 * alloc.c (widen_to_Lisp_Object): New static function.
4960 (mark_memory): Also mark Lisp_Objects by fetching pointer words
4961 and widening them to Lisp_Objects. This would work even if
4962 USE_LSB_TAG is defined and wide integers are used, which might
4963 happen in a future version of Emacs.
4965 2012-02-25 Chong Yidong <cyd@gnu.org>
4967 * fileio.c (Ffile_selinux_context, Fset_file_selinux_context):
4968 Doc fix.
4970 * xselect.c (Fx_selection_exists_p): Doc fix.
4971 (x_clipboard_manager_save_all): Print an informative message
4972 before saving to clipboard manager.
4974 2012-02-24 Chong Yidong <cyd@gnu.org>
4976 * keyboard.c (process_special_events): Handle all X selection
4977 requests in kbd_buffer, not just the next one (Bug#8869).
4979 2012-02-23 Chong Yidong <cyd@gnu.org>
4981 * xfns.c (Fx_create_frame): Avoid window-configuration-change-hook
4982 call when setting menu-bar-lines and tool-bar-lines parameters.
4983 (unwind_create_frame_1): New helper function.
4985 * window.c (inhibit_window_configuration_change_hook): New var.
4986 (run_window_configuration_change_hook): Obey it.
4987 (syms_of_window): Initialize it.
4989 2012-02-22 Chong Yidong <cyd@gnu.org>
4991 * xterm.c (x_draw_image_relief): Add missing type check for
4992 Vtool_bar_button_margin (Bug#10743).
4994 2012-02-21 Chong Yidong <cyd@gnu.org>
4996 * fileio.c (Vfile_name_handler_alist): Doc fix.
4998 * buffer.c (Fget_file_buffer): Protect against invalid file
4999 handler return value.
5001 2012-02-20 Paul Eggert <eggert@cs.ucla.edu>
5003 * .gdbinit (xreload): Don't assume EMACS_INT fits in 'long'
5004 when computing $valmask.
5006 Fix crash due to non-contiguous EMACS_INT (Bug#10780).
5007 * lisp.h (VALBITS): Move definition up, so that USE_LSB_TAG can use it.
5008 (USE_LSB_TAG): Do not define if UINTPTR_MAX >> VALBITS == 0.
5009 It's useless in that case, and it can cause problems on hosts
5010 that allocate halves of EMACS_INT values separately.
5011 Reported by Dan Horák. Diagnosed by Andreas Schwab in
5012 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=10780#30>.
5013 * mem-limits.h (EXCEEDS_LISP_PTR): Define to 0 on hosts where
5014 UINTPTR_MAX >> VALBITS == 0. This is required by the above change;
5015 it avoids undefined behavior on hosts where shifting right by more
5016 than the word width has undefined behavior.
5018 2012-02-19 Chong Yidong <cyd@gnu.org>
5020 * fileio.c (Ffile_name_directory, Ffile_name_nondirectory)
5021 (Funhandled_file_name_directory, Ffile_name_as_directory)
5022 (Fdirectory_file_name, Fexpand_file_name)
5023 (Fsubstitute_in_file_name): Protect against invalid file handler
5024 return values (Bug#10845).
5026 2012-02-18 Eli Zaretskii <eliz@gnu.org>
5028 * .gdbinit (pitx): Fix incorrect references to fields of the
5029 iterator stack.
5031 2012-02-17 Chong Yidong <cyd@gnu.org>
5033 * syntax.c (Fscan_lists): Doc fix (Bug#10833).
5035 2012-02-15 Paul Eggert <eggert@cs.ucla.edu>
5037 * image.c (MAX_IMAGE_SIZE): Increase from 6.0 to 10.0; see
5038 <http://lists.gnu.org/archive/html/emacs-devel/2012-02/msg00540.html>.
5040 2012-02-15 Chong Yidong <cyd@gnu.org>
5042 * eval.c (Fdefvar, Fdefconst): Doc fix; note that the variable is
5043 marked as special. Also, starting docstrings with * is obsolete.
5045 2012-02-13 Andreas Schwab <schwab@linux-m68k.org>
5047 * gnutls.c (emacs_gnutls_write): Fix last change.
5049 2012-02-13 Lars Ingebrigtsen <larsi@gnus.org>
5051 * gnutls.c (emacs_gnutls_write): Set errno appropriately for
5052 send_process.
5054 2012-02-13 Stefan Monnier <monnier@iro.umontreal.ca>
5056 * keymap.c (Fsingle_key_description): Handle char ranges.
5058 2012-02-12 Chong Yidong <cyd@gnu.org>
5060 * xdisp.c (handle_stop): Avoid assigning -1 to it->face_id here,
5061 as that creates a dangerous corner case.
5063 * window.c (Fdelete_window_internal): Invalidate the mouse
5064 highlight (Bug#9904).
5066 2012-02-12 Glenn Morris <rgm@gnu.org>
5068 * xselect.c (Fx_own_selection_internal)
5069 (Fx_get_selection_internal, Fx_disown_selection_internal)
5070 (Fx_selection_owner_p, Fx_selection_exists_p): Doc fixes.
5071 * nsselect.m (Fx_own_selection_internal)
5072 (Fx_disown_selection_internal, Fx_selection_exists_p)
5073 (Fx_selection_owner_p, Fx_get_selection_internal):
5074 Sync docs and argument specs with the xselect.c versions.
5076 2012-02-11 Lars Ingebrigtsen <larsi@gnus.org>
5078 * gnutls.c (emacs_gnutls_write): Don't infloop if sendto fails.
5080 2012-02-11 Eli Zaretskii <eliz@gnu.org>
5082 * w32select.c (Fx_selection_exists_p): Sync doc string and
5083 argument list with xselect.c. (Bug#10783)
5085 * w16select.c (Fx_selection_exists_p): Sync doc string and
5086 argument list with xselect.c. (Bug#10783)

5094 * coding.c (produce_chars): Fix updating of src_end (Bug#10701).
5096 2012-02-07 Chong Yidong <cyd@gnu.org>
5098 * buffer.c (Fbuffer_local_variables)
5099 (buffer_lisp_local_variables): Handle unbound vars correctly;
5100 don't let Qunbound leak into Lisp.
5102 2012-02-07 Glenn Morris <rgm@gnu.org>
5104 * image.c (Fimagemagick_types): Doc fix.
5106 * image.c (imagemagick-render-type): Change it from a lisp object
5107 to an integer. Move the doc here from the lisp manual.
5108 Treat all values not equal to 0 the same.
5110 2012-02-06 Chong Yidong <cyd@gnu.org>
5112 * doc.c (store_function_docstring): Avoid applying docstring of
5113 alias to base function (Bug#2603).
5115 2012-02-04 Andreas Schwab <schwab@linux-m68k.org>
5117 * .gdbinit (pp1, pv1): Remove redundant defines.
5118 (pr): Use pp.
5120 2012-02-04 Chong Yidong <cyd@gnu.org>
5122 * nsterm.m: Declare a global (Bug#10694).
5124 2012-02-04 Eli Zaretskii <eliz@gnu.org>

5127 Include --enable-checking, if specified, in the return value.
5129 2012-02-04 Martin Rudalics <rudalics@gmx.at>
5131 * dispnew.c (change_frame_size_1): Calculate new_frame_total_cols
5132 after rounding frame sizes. (Bug#9723)
5134 2012-02-04 Eli Zaretskii <eliz@gnu.org>
5136 * keyboard.c (adjust_point_for_property): Don't position point
5137 before BEGV. (Bug#10696)
5139 2012-02-03 Paul Eggert <eggert@cs.ucla.edu>
5141 Handle overflow when computing char display width (Bug#9496).
5142 * character.c (char_width): Return EMACS_INT, not int.
5143 (char_width, c_string_width): Check for overflow when
5144 computing the width; this is possible now that individual
5145 characters can have unbounded width. Problem introduced
5146 by merge from Emacs 23 on 2012-01-19.
5148 2012-02-02 Michael Albinus <michael.albinus@gmx.de>
5150 * dbusbind.c (Fdbus_register_method): Mention the return value
5151 :ignore in the docstring.

5163 2012-02-02 Kenichi Handa <handa@m17n.org>
5165 (x_produce_glyphs): Cancel previous change. If cmp->glyph_len is
5166 0, do not call append_composite_glyph.
5168 2012-02-02 Kenichi Handa <handa@m17n.org>
5170 * xdisp.c (BUILD_COMPOSITE_GLYPH_STRING): Initialize first_s to
5171 NULL (Bug#6988).
5172 (x_produce_glyphs): If the component of a composition is a null
5173 string, set it->pixel_width to 1 to avoid zero-width glyph.
5175 2012-02-01 Eli Zaretskii <eliz@gnu.org>
5177 * ralloc.c (resize_bloc, r_alloc_sbrk): Don't call memmove if its
5178 first 2 arguments are identical. This makes inserting large
5179 output from a subprocess an order of magnitude faster on
5180 MS-Windows, where all sbrk'ed memory is always contiguous.
5182 2012-01-31 Glenn Morris <rgm@gnu.org>
5184 * nsterm.m (syms_of_nsterm) <x-toolkit-scroll-bars>:

5220 2012-01-21 Chong Yidong <cyd@gnu.org>
5222 * floatfns.c (Fcopysign): Make the second argument non-optional,
5223 since nil is not allowed anyway.
5225 2012-01-21 Andreas Schwab <schwab@linux-m68k.org>
5227 * process.c (read_process_output): Use p instead of XPROCESS (proc).

5234 Rewrite doc-strings.
5236 2012-01-19 Kenichi Handa <handa@m17n.org>
5238 * character.c (char_width): New function.
5239 (Fchar_width, c_string_width, lisp_string_width):
5240 Use char_width (Bug#9496).
5242 2012-01-16 Martin Rudalics <rudalics@gmx.at>
5244 * window.c (Vwindow_persistent_parameters): New variable.
5245 (Fset_window_configuration, save_window_save): Handle persistent
5246 window parameters.
5248 2012-01-14 Eli Zaretskii <eliz@gnu.org>
5250 * w32fns.c (signal_user_input): Don't do a QUIT, to avoid

5260 highlight ends on a newline. (Bug#10464)
5261 (mouse_face_from_buffer_pos): Fix off-by-one error in calculating
5262 he end column for display of highlight that ends on a newline
5263 before a R2L line.

5795 Standardize on VIRT_ADDR_VARIES behavior (Bug#10042).
5796 Otherwise, valgrind does not work on some platforms.
5797 Problem reported by Andreas Schwab in
5798 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00081.html>.
5799 * puresize.h (pure, PURE_P): Always behave as if VIRT_ADDR_VARIES
5800 is set, removing the need for VIRT_ADDRESS_VARIES.
5801 (PURE_P): Use a more-efficient implementation that needs just one
5802 comparison, not two: on x86-64 with GCC 4.6.2, this cut down the
5803 number of instructions from 6 (xorl, cmpq, jge, xorl, cmpq, setge)
5804 to 4 (xorl, subq, cmpq, setbe).
5805 * alloc.c (pure): Always extern now, since that's the
5806 VIRT_ADDR_VARIES behavior.
5807 (PURE_POINTER_P): Use a single comparison, not two, for
5808 consistency with the new puresize.h.
5809 * lisp.h (PNTR_COMPARISON_TYPE): Remove; no longer needed.
5810 * m/ibms390.h, m/intel386.h, m/template.h, s/cygwin.h, s/hpux10-20.h:

5816 (erase_phys_cursor, update_window_cursor, show_mouse_face)
5817 (cursor_in_mouse_face_p): If the cursor position is out of bounds,
5818 behave as if the cursor position were at the window margin.
5820 * window.c (get_phys_cursor_glyph): If the window is hscrolled,
5821 and the cursor position is out of bounds, behave as if the cursor
5822 position were at the window margin. (Bug#10075)
5824 2011-11-18 Chong Yidong <cyd@gnu.org>
5826 * window.c (Fwindow_combination_limit): Make first argument
5827 non-optional, since it is meaningless for live windows like the

5845 (add_row_entry): Add xassert to verify that ROW's hash code is valid.
5847 * xdisp.c (row_hash): New function, body extracted from
5848 compute_line_metrics.
5849 (compute_line_metrics): Call row_hash, instead of computing the
5850 hash code inline.
5852 * dispnew.c (verify_row_hash): Call row_hash for computing the
5853 hash code of a row, instead of duplicating code from xdisp.c.
5855 * dispextern.h (row_hash): Add prototype.
5857 2011-11-18 Tassilo Horn <tassilo@member.fsf.org>

5893 2011-11-14 Eli Zaretskii <eliz@gnu.org>
5895 * xdisp.c (display_line): Move the call to
5896 highlight_trailing_whitespace before the call to
5897 compute_line_metrics, since the latter needs to see the final
5898 faces of all the glyphs to compute ROW's hash value.
5899 Fixes assertion violations in row_equal_p. (Bug#10035)
5901 2011-11-14 Juanma Barranquero <lekktu@gmail.com>
5903 * w32proc.c (reader_thread): Don't check pending input if cp->fd < 0,
5904 just return (bug#10044).

5908 * makefile.w32-in (HEAPSIZE): New variable, allows to build temacs
5909 with user-defined heap size. Bump the default size of the temacs
5910 heap to 27MB, to avoid memory warning when running temacs.
5911 ($(TEMACS)): Use HEAPSIZE instead of a hardcoded value.
5913 * dispnew.c (scrolling_window): Fix incorrect indices in accessing
5914 current_matrix and desired_matrix. (Bug#9990)
5915 (verify_row_hash) [XASSERTS]: New function.
5916 (adjust_glyph_matrix, row_equal_p): Use it in xassert to verify
5917 that the hash value of glyph rows is correct.

5960 2011-11-08 Paul Eggert <eggert@cs.ucla.edu>
5962 Avoid some portability problems by eschewing 'extern inline' functions.
5963 The trivial performance wins aren't worth the portability hassles; see

5965 et seq.
5966 * dispextern.h (window_box, window_box_height, window_text_bottom_y)
5967 (window_box_width, window_box_left, window_box_left_offset)
5968 (window_box_right, window_box_right_offset): Undo previous change,
5969 by removing the "extern"s.
5970 * intervals.c (adjust_intervals_for_insertion)
5971 (adjust_intervals_for_deletion): Undo previous change,
5972 making these static again.
5973 (offset_intervals, temp_set_point_both, temp_set_point)
5974 (copy_intervals_to_string): No longer inline.
5975 * xdisp.c (window_text_bottom_y, window_box_width)

6040 (window_box_width, window_box_left, window_box_left_offset)
6041 (window_box_right, window_box_right_offset): Declare extern.
6042 Otherwise, these inline functions do not conform to C99 and
6043 are miscompiled by Microsoft compilers. Reported by Eli Zaretskii in
6044 <http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
6045 * intervals.c (adjust_intervals_for_insertion)
6046 (adjust_intervals_for_deletion): Now extern, because otherwise the

6048 (static_offset_intervals): Remove.
6049 (offset_intervals): Rewrite using the old contents of
6050 static_offset_intervals. The old version didn't conform to C99
6051 because an extern inline function contained a reference to an

6203 * xterm.c: Include X11/Xproto.h if HAVE_GTK3.
6204 (x_error_handler): Ignore BadMatch for X_SetInputFocus for
6205 HAVE_GTK3 (Bug#9869).
6207 * gtkutil.c (xg_win_to_widget, xg_event_is_for_menubar): Initialize
6208 type to GDK_NOTHING so valgrind does not complain (Bug#9901).
6210 * xterm.h (x_display_info): Add Xatom_net_wm_state_hidden (Bug#9893).
6212 * xterm.c: Declare x_handle_net_wm_state to return int.
6213 (handle_one_xevent): Check if we are iconified but don't have
6214 _NET_WM_STATE_HIDDEN. If do, treat as deiconify (Bug#9893).
6215 (get_current_wm_state): Return non-zero if not hidden,
6216 check for _NET_WM_STATE_HIDDEN (Bug#9893).
6217 (do_ewmh_fullscreen): Ignore return value from get_current_wm_state.
6218 (x_handle_net_wm_state): Return what get_current_wm_state returns.
6219 (x_term_init): Initialize dpyinfo->Xatom_net_wm_state_hidden.
6221 2011-10-29 Paul Eggert <eggert@cs.ucla.edu>
6223 * alloc.c (which_symbols): Declare EXTERNALLY_VISIBLE,
6224 so that this new function doesn't get optimized away by a
6225 whole-program optimizer. Make the 2nd arg EMACS_INT, not int.
6227 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
6229 * frame.h (MOUSE_HL_INFO): Remove excess parens.
6231 2011-10-29 Eli Zaretskii <eliz@gnu.org>
6233 Fix the `xbytecode' command.
6234 * .gdbinit (xprintbytestr): New command.
6235 (xwhichsymbols): Rename from `which'; all callers changed.
6236 (xbytecode): Print the byte-code string as well.
6238 2011-10-29 Kim Storm <storm@cua.dk>
6240 * alloc.c (which_symbols): New function.
6242 2011-10-29 Andreas Schwab <schwab@linux-m68k.org>
6244 * minibuf.c (read_minibuf_noninteractive): Allow reading empty
6245 line. (Bug#9903)
6247 2011-10-29 Glenn Morris <rgm@gnu.org>
6249 * process.c (wait_reading_process_output): Revert 2009-08-30 change.
6250 Not clear what it was for, and it causes various bugs. (Bug#9839)
6252 2011-10-28 Eli Zaretskii <eliz@gnu.org>
6254 * xdisp.c (note_mouse_highlight): Initialize `part', to avoid a
6255 possible random value that matches one of those tested as
6256 condition to clear the mouse face.
6258 2011-10-28 Chong Yidong <cyd@gnu.org>
6260 * xdisp.c (note_mouse_highlight): Fix use of uninitialized var.
6262 2011-10-28 Dan Nicolaescu <dann@ics.uci.edu>
6264 * window.c (make_window): Initialize phys_cursor_on_p.
6266 2011-10-28 Stefan Monnier <monnier@iro.umontreal.ca>
6268 * lisp.h (struct Lisp_Symbol): Update comments.
6270 2011-10-28 Juanma Barranquero <lekktu@gmail.com>
6272 * w32font.c (w32_load_unicows_or_gdi32): Add missing return.
6274 2011-10-28 Eli Zaretskii <eliz@gnu.org>
6276 Fix Emacs on Windows 9X (bug#8562). Thanks to oslsachem
6277 <oslsachem@gmail.com> for helping to debug this.
6279 * w32font.c (g_b_init_is_w9x, g_b_init_get_outline_metrics_w)
6280 (g_b_init_get_text_metrics_w, g_b_init_get_glyph_outline_w)
6281 (g_b_init_get_glyph_outline_w): New static variables.
6282 (GetOutlineTextMetricsW_Proc, GetTextMetricsW_Proc)
6283 (GetGlyphOutlineW_Proc): New typedefs.
6284 (w32_load_unicows_or_gdi32, get_outline_metrics_w)
6285 (get_text_metrics_w, get_glyph_outline_w, globals_of_w32font):
6286 New functions.
6287 (w32font_open_internal, compute_metrics):
6288 Call get_outline_metrics_w, get_text_metrics_w, and get_glyph_outline_w
6289 instead of calling the "wide" APIs directly.
6291 * emacs.c (main) [HAVE_NTGUI]: Call globals_of_w32font.
6293 * w32.h (syms_of_w32font): Add prototype.
6295 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
6297 * window.c (Fframe_root_window, Fframe_first_window, Fwindow_end)
6298 (Fframe_selected_window, Ftemp_output_buffer_show, Fnext_window)
6299 (Fdelete_window_internal, Fwindow_parameters): Fix typos in docstrings.
6300 (Fmove_to_window_line): Doc fix.
6302 2011-10-27 Chong Yidong <cyd@gnu.org>
6304 * process.c (make_process): Set gnutls_state to NULL.
6306 * gnutls.c (emacs_gnutls_deinit): Deinit the gnutls_state if it is
6307 non-NULL, regardless of GNUTLS_INITSTAGE.
6308 (Fgnutls_boot): Cleanups. Call emacs_gnutls_deinit if we signal
6309 an error. Set process slots as soon as we allocate them.
6311 * gnutls.h (GNUTLS_LOG, GNUTLS_LOG2): Fix macros.
6313 2011-10-27 Chong Yidong <cyd@gnu.org>
6315 * gnutls.c (emacs_gnutls_deinit): New function.
6316 Deallocate credentials structures as well as calling gnutls_deinit.
6317 (Fgnutls_deinit, Fgnutls_boot): Use it.
6319 * process.c (make_process): Initialize GnuTLS credentials to NULL.
6320 (deactivate_process): Call emacs_gnutls_deinit.
6322 2011-10-27 Juanma Barranquero <lekktu@gmail.com>
6324 * image.c (x_create_x_image_and_pixmap):
6325 * w32.c (sys_rename, w32_delayed_load):
6326 * w32font.c (fill_in_logfont):
6327 * w32reg.c (x_get_string_resource): Silence compiler warnings.
6329 2011-10-26 Juanma Barranquero <lekktu@gmail.com>
6331 * w32fns.c (w32_default_color_map): New function,
6332 extracted from Fw32_default_color_map.
6333 (Fw32_default_color_map, Fx_open_connection): Use it. (Bug#9785)
6335 2011-10-25 Paul Eggert <eggert@cs.ucla.edu>
6337 * dispextern.h (Fcontrolling_tty_p): New decl (Bug#6649 part 2).
6339 2011-10-25 Stefan Monnier <monnier@iro.umontreal.ca>
6341 * keyboard.c (test_undefined): New function (bug#9751).
6342 (read_key_sequence): Use it to detect when a key is bound to `undefined'.
6344 2011-10-25 Enami Tsugutomo <tsugutomo.enami@jp.sony.com>
6346 * sysdep.c (init_sys_modes): Fix the check for the controlling
6347 terminal (Bug#6649).
6349 2011-10-20 Eli Zaretskii <eliz@gnu.org>
6351 * dispextern.h (struct bidi_it): New member next_en_type.
6353 * bidi.c (bidi_line_init): Initialize the next_en_type member.
6354 (bidi_resolve_explicit_1): When next_en_pos is valid for the
6355 current character, check also for next_en_type being WEAK_EN.
6356 (bidi_resolve_weak): Don't enter the expensive loop if the current
6357 position is before next_en_pos. Record the bidi type of the first
6358 non-ET, non-BN character we find, in addition to its position.
6359 (bidi_level_of_next_char): Invalidate next_en_type when
6360 next_en_pos is over-stepped.
6362 2011-10-20 Paul Eggert <eggert@cs.ucla.edu>
6364 Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
6365 * editfns.c: Rewrite current-time-zone so that it invokes
6366 the equivalent of (format-time-string "%Z") to get the time zone name.
6367 This fixes a bug when the time zone name contains characters that
6368 need converting from the system time locale to Emacs internal format.
6369 This fixes a shortcoming that I introduced in my 1999-10-19 patch:
6370 that patch fixed format-time-string to do the conversion, but
6371 I forgot to fix current-time-zone.
6372 (format_time_string): New function, containing most of
6373 what Fformat_time_string used to contain.
6374 (Fformat_time_string): Rewrite in terms of format_time_string.
6375 This doesn't change this function's behavior.
6376 (current-time-zone): Rewrite to use format_time_string.
6377 This fixes the bug reported by Michael Schierl in
6378 <http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.
6379 Jason Rumney's 2007-06-07 change worked around this bug, but
6380 didn't fix it.
6381 * systime.h (tzname, timezone): Remove no-longer-used declarations.
6383 2011-10-19 Eli Zaretskii <eliz@gnu.org>
6385 * xdisp.c (start_display): If the character at POS is displayed
6386 via a display vector, reset IT->current.dpvec_index to zero.
6387 (try_window_reusing_current_matrix): If a line ends in a display
6388 vector or the next line starts in a display vector, continue
6389 redrawing the window even though the character position of
6390 start_row was reached.
6391 (Bug#9771, part 2)
6393 2011-10-18 Chong Yidong <cyd@gnu.org>
6395 * xdisp.c (get_next_display_element): Handle U+2010 and U+2011
6396 with nobreak-char-display too.
6398 2011-10-18 Eli Zaretskii <eliz@gnu.org>
6400 Fix part 3 of bug#9771.
6401 * bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
6402 (bidi_resolve_neutral): Don't enter the expensive loop looking for
6403 non-neutral characters if the current character is a paragraph
6404 separator (a.k.a. Newline). This avoids running the same
6405 expensive loop twice, once when we consume the preceding newline
6406 and the other time when the line actually needs to be displayed.
6407 Avoid the loop when we see neutrals on the base embedding level
6408 following a character whose directionality is the same as the
6409 paragraph's. This avoids running the expensive loop when a line
6410 ends in a long sequence of neutrals, like control characters.
6411 Add assertion against STRONG_AL type. Slightly rearrange code
6412 that determines the type of a neutral given the first non-neutral
6413 that follows it.
6414 (bidi_level_of_next_char): Set next_en_pos to zero when
6415 invalidating its info.
6417 2011-10-17 Eli Zaretskii <eliz@gnu.org>
6419 * xdisp.c (push_display_prop): Determine whether to record string
6420 or buffer position by IT->string, not by IT->method. Allow
6421 GET_FROM_DISPLAY_VECTOR as IT->method on entry. (Bug#9771, part 4)
6422 (move_it_vertically_backward): Don't look for character position
6423 immediately after the newline when in a continuation line.
6424 (Bug#9771, part 1)
6426 2011-10-15 Martin Rudalics <rudalics@gmx.at>
6428 * window.c (coordinates_in_window): Rewrite and delabelize
6429 vertical border check. (Bug#5357) (Bug#9618)
6431 2011-10-14 Stefan Monnier <monnier@iro.umontreal.ca>
6433 * xterm.c (frame_highlight, frame_unhighlight): Ignore unexplained
6434 errors in XSetWindowBorder (bug#9310).
6436 2011-10-13 Dmitry Antipov <dmantipov@yandex.ru>
6438 * editfns.c (Fset_time_zone_rule): Replace free with xfree to
6439 avoid crash when xmalloc overrun checking is enabled.
6441 2011-10-13 Eli Zaretskii <eliz@gnu.org>
6443 * xdisp.c (Fcurrent_bidi_paragraph_direction): Initialize
6444 itb.paragraph_dir to NEUTRAL_DIR. Fixes an occasional incorrect
6445 cursor motion with <left> and <right> arrow keys.
6447 * bidi.c (bidi_init_it): Don't initialize paragraph_dir here, as
6448 some callers set that themselves.
6450 2011-10-12 Eli Zaretskii <eliz@gnu.org>
6452 * xdisp.c (find_row_edges): Handle the case where ROW comes from a
6453 display string and the previous row comes from the same string and
6454 is empty. (Bug#9739) (Bug#9738)
6456 2011-10-12 Stefan Monnier <monnier@iro.umontreal.ca>
6458 * doc.c (get_doc_string): Encode file name (bug#9735).
6460 2011-10-12 Eli Zaretskii <eliz@gnu.org>
6462 * bidi.c (bidi_level_of_next_char):
6463 * xdisp.c (get_visually_first_element): Remove old incorrect
6464 comments regarding the Unicode Line Separator character.
6466 * bidi.c (bidi_init_it): Initialize paragraph_dir to NEUTRAL_DIR.
6468 2011-10-12 Dmitry Antipov <dmantipov@yandex.ru>
6470 * alloc.c (Fgc_status): Do not access beyond zombies array
6471 boundary if nzombies > MAX_ZOMBIES.
6472 * alloc.c (dump_zombies): Add missing format specifier.
6474 2011-10-12 Paul Eggert <eggert@cs.ucla.edu>
6476 * xdisp.c (set_cursor_from_row): Simplify conditionals,
6477 to pacify GCC 4.6.1 x86-64 with -O2 -Wstrict-overflow.
6479 * lread.c (read_escape): Allow hex escapes as large as ?\xfffffff.
6480 Some packages use them to denote characters with modifiers.
6482 2011-10-11 Andreas Schwab <schwab@linux-m68k.org>
6484 * lisp.h (GCPRO1_VAR, GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR)
6485 (GCPRO5_VAR, GCPRO6_VAR, UNGCPRO_VAR): Add whitespace to avoid
6486 matching a pp-number. Rename parameter var to var1.
6488 2011-10-11 Stefan Monnier <monnier@iro.umontreal.ca>
6490 * minibuf.c (Finternal_complete_buffer): Fix last change (bug#9709).
6492 2011-10-08 Glenn Morris <rgm@gnu.org>
6494 * callint.c (Fcall_interactively): Give a more explicit error for the
6495 'c' case with a non-character input. (Bug#8479)
6497 2011-10-08 Eli Zaretskii <eliz@gnu.org>
6499 * xdisp.c (hscroll_window_tree): Support hscroll in right-to-left
6500 lines.
6501 (set_cursor_from_row): Fix cursor positioning in mixed L2R+R2L
6502 lines that are hscrolled on the left.
6504 * dispnew.c (buffer_posn_from_coords): Account for a possible
6505 presence of header-line. (Bug#4426)
6507 2011-10-07 Stefan Monnier <monnier@iro.umontreal.ca>
6509 * buffer.c (syms_of_buffer) <enable-multibyte-characters>:
6510 Don't advertise functionality which we discourage or doesn't work.
6512 2011-10-07 Paul Eggert <eggert@cs.ucla.edu>
6514 * alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
6515 or sizeof. __alignof__ gives the wrong answer on Fedora x86-64
6516 with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
6517 this makes Emacs dump core during garbage collection on rare
6518 occasions. sizeof is obviously inferior to offsetof here, so
6519 stick with offsetof.
6520 (GC_POINTER_ALIGNMENT): New macro.
6521 (mark_memory): Omit 3rd (offset) arg; caller changed.
6522 Don't assume EMACS_INT alignment is the same as pointer alignment.
6524 2011-10-03 Stefan Monnier <monnier@iro.umontreal.ca>
6526 * keyboard.c (read_key_sequence_remapped): New var.
6527 (read_key_sequence): Compute remapping in the right buffer.
6528 (command_loop_1): Use read_key_sequence's remapping directly.
6530 2011-10-02 Stefan Monnier <monnier@iro.umontreal.ca>
6532 * dired.c (file_name_completion): Don't expand file name.
6533 (Ffile_name_completion, Ffile_name_all_completions): Expand file name
6534 before checking file name handler.
6536 * minibuf.c (Finternal_complete_buffer): Only show internal buffers if
6537 they've been requested explicitly (bug#9591).
6539 2011-10-01 Andreas Schwab <schwab@linux-m68k.org>
6541 * keymap.c (Fsingle_key_description): Use make_specified_string
6542 instead of build_string to build string from push_key_description.
6543 (Bug#5193)
6545 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
6547 * buffer.h (struct buffer): Use time_t, not int, for a time stamp.
6548 This fixes a Y2038 bug on 64-bit hosts.
6549 * buffer.c (reset_buffer):
6550 * fileio.c (Fdo_auto_save, Fset_buffer_auto_saved)
6551 (Fclear_buffer_auto_save_failure):
6552 Use 0, not -1, to represent an unset failure time, since time_t
6553 might not be signed.
6555 Remove dependency on glibc malloc internals.
6556 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6557 Move back here from lisp.h, but with their new implementations.
6558 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
6559 (XMALLOC_OVERRUN_SIZE_SIZE): Move these new lisp.h macros here.
6560 * charset.c (charset_table_init): New static var.
6561 (syms_of_charset): Use it instead of xmalloc. This removes a
6562 dependency on glibc malloc internals. See Eli Zaretskii's comment in
6563 <http://lists.gnu.org/archive/html/emacs-devel/2011-09/msg00815.html>.
6564 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6565 Move back to alloc.c.
6566 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
6567 (XMALLOC_OVERRUN_SIZE_SIZE): Move to alloc.c.
6569 2011-09-30 Jan Djärv <jan.h.d@swipnet.se>
6571 * nsterm.m (windowDidResize): Call x_set_window_size only when
6572 ns_in_resize is true. Otherwise set pixelwidth/height and
6573 call change_frame_size (Bug#9628).
6575 2011-09-30 Paul Eggert <eggert@cs.ucla.edu>
6577 Port --enable-checking=all to Fedora 14 x86-64.
6578 * charset.c (syms_of_charset): Also account for glibc malloc's
6579 internal overhead when calculating the initial malloc maximum.
6581 Port --enable-checking=all to Fedora 14 x86.
6582 * alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6583 Move to lisp.h.
6584 (xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
6585 (overrun_check_realloc, overrun_check_free):
6586 Use XMALLOC_OVERRUN_SIZE_SIZE, not sizeof (size_t).
6587 That way, xmalloc returns a properly-aligned pointer even if
6588 XMALLOC_OVERRUN_CHECK is defined. The old debugging code happened
6589 to align OK on typical 64-bit hosts, but not on Fedora 14 x86.
6590 * charset.c (syms_of_charset): Take XMALLOC_OVERRUN_CHECK_OVERHEAD
6591 into account when calculating the initial malloc maximum.
6592 * lisp.h (XMALLOC_OVERRUN_CHECK_OVERHEAD, XMALLOC_OVERRUN_CHECK_SIZE):
6593 Move here from alloc.c, so that charset.c can use it too.
6594 Properly align; the old code wasn't right for common 32-bit hosts
6595 when configured with --enable-checking=all.
6596 (XMALLOC_BASE_ALIGNMENT, COMMON_MULTIPLE, XMALLOC_HEADER_ALIGNMENT)
6597 (XMALLOC_OVERRUN_SIZE_SIZE): New macros.
6599 2011-09-29 Eli Zaretskii <eliz@gnu.org>
6601 * sysdep.c (snprintf) [!EOVERFLOW]: If EOVERFLOW is not defined,
6602 use EDOM.
6604 2011-09-28 Eli Zaretskii <eliz@gnu.org>
6606 * xdisp.c (compute_display_string_end): If there's no display
6607 string at CHARPOS, return -1.
6609 * bidi.c (bidi_fetch_char): When compute_display_string_end
6610 returns a negative value, treat the character as a normal
6611 character not covered by a display string. (Bug#9624)
6613 2011-09-28 Juanma Barranquero <lekktu@gmail.com>
6615 * lread.c (Fread_from_string): Fix typo in docstring.
6617 2011-09-27 Eli Zaretskii <eliz@gnu.org>
6619 * xdisp.c (handle_invisible_prop): If invisible text ends on a
6620 newline, reseat the iterator instead of bidi-iterating there one
6621 character at a time. (Bug#9610)
6622 (BUFFER_POS_REACHED_P, move_it_in_display_line_to): Bail when past
6623 TO_CHARPOS if the bidi iterator is at base embedding level.
6625 2011-09-27 Andreas Schwab <schwab@linux-m68k.org>
6627 * lread.c (readevalloop): Use correct code for NBSP.
6628 (read1): Likewise. (Bug#9608)
6630 2011-09-25 Michael Albinus <michael.albinus@gmx.de>
6632 * dbusbind.c (Fdbus_register_signal): When service is not
6633 registered, use nil in Vdbus_registered_objects_table. (Bug#9581)
6635 2011-09-25 Glenn Morris <rgm@gnu.org>
6637 * buffer.c (truncate-lines): Doc fix.
6639 2011-09-24 Chong Yidong <cyd@stupidchicken.com>
6641 * window.c (Fwindow_prev_buffers, Fset_window_prev_buffers)
6642 (Fset_window_next_buffers): Doc fix.
6644 2011-09-24 Glenn Morris <rgm@gnu.org>
6646 * minibuf.c (read_minibuf): Disable line truncation. (Bug#5715)
6648 2011-09-24 Paul Eggert <eggert@cs.ucla.edu>
6650 Fix minor problems found by static checking.
6651 * xdisp.c (string_from_display_spec): Don't assume vecsize fits in int.
6652 * indent.c (Fvertical_motion): Fix == vs = typo.
6654 2011-09-24 Eli Zaretskii <eliz@gnu.org>
6656 * dispnew.c (syms_of_display) <redisplay-dont-pause>:
6657 Default value is now t. Doc fix.
6659 * indent.c (Fvertical_motion): Compute and apply the overshoot
6660 logic when moving up, not only when moving down. Fix the
6661 confusing name and values of the it_overshoot_expected variable;
6662 logic changes accordingly. (Bug#9254) (Bug#9549)
6664 * xdisp.c (pos_visible_p): Produce correct pixel coordinates when
6665 CHARPOS is covered by a display string which includes newlines.
6666 (move_it_vertically_backward): Avoid inflooping when START_CHARPOS
6667 is covered by a display string with embedded newlines.
6669 2011-09-24 Michael Albinus <michael.albinus@gmx.de>
6671 * dbusbind.c (Fdbus_register_signal): Add match rule to
6672 Vdbus_registered_objects_table. (Bug#9581)
6673 (Fdbus_register_method, Vdbus_registered_objects_table):
6674 Fix docstring.
6676 2011-09-24 Jim Meyering <meyering@redhat.com>
6678 do not ignore write error for any output size
6679 The previous change was incomplete.
6680 While it makes emacs --batch detect the vast majority of stdout
6681 write failures, errors were still ignored whenever the output size is
6682 k * (BUFSIZ+1) - 4. E.g., on a system with BUFSIZ of 4096,
6683 $ emacs --batch --eval '(print (format "%4093d" 0))' > /dev/full \
6684 && echo FAIL: ignored write error
6685 FAIL: ignored write error
6686 $ emacs --batch --eval '(print (format "%20481d" 0))' > /dev/full \
6687 && echo FAIL: ignored write error
6688 FAIL: ignored write error
6689 * emacs.c (Fkill_emacs): Also test ferror. (Bug#9574)
6691 2011-09-23 Andreas Schwab <schwab@linux-m68k.org>
6693 * emacs.c (Fkill_emacs): In noninteractive mode exit
6694 non-successfully if a write error occurred on stdout. (Bug#9574)
6696 2011-09-21 Eli Zaretskii <eliz@gnu.org>
6698 * xdisp.c (pop_it): Allow it->object that is a cons cell to pass
6699 the xassert test.
6701 * dispextern.h (struct it): Update the comment documenting what
6702 can it->OBJECT be.
6704 2011-09-20 Eli Zaretskii <eliz@gnu.org>
6706 * xdisp.c (set_cursor_from_row): If the row ends in a newline from
6707 a display string, extend search for cursor position to end of row.
6708 (find_row_edges): If the row ends in a newline from a display
6709 string, increment its MATRIX_ROW_END_CHARPOS by one. (Bug#9549)
6710 Handle the case of a display string with multiple newlines.
6711 (Fcurrent_bidi_paragraph_direction): Fix search for previous
6712 non-empty line. Fixes confusing cursor motion with arrow keys at
6713 the beginning of a line that starts with whitespace.
6715 2011-09-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
6717 * lread.c (Fread_from_string): Document what FINAL-STRING-INDEX is
6718 (bug#9493).
6720 2011-09-18 Chong Yidong <cyd@stupidchicken.com>
6722 * xfns.c (Fx_create_frame): Handle the bitmapIcon resource as
6723 boolean (Bug#9154).
6725 2011-09-18 Eli Zaretskii <eliz@gnu.org>
6727 * xdisp.c (display_line): Record maximum and minimum buffer
6728 positions even if no glyphs were produced (e.g., by a zero-width
6729 stretch). Fixes bug#9530 on a TTY. Under word-wrap, don't record
6730 buffer positions that will be removed from the glyph row because
6731 they don't fit.
6732 (produce_stretch_glyph): Fix a bug in :align-to on a TTY when the
6733 column is beyond frame width: don't subtract 1 "pixel" when
6734 computing width of the stretch.
6735 (reseat_at_next_visible_line_start): Undo the change made on
6736 2011-09-17 that saved paragraph information and restored it after
6737 the call to `reseat'. (Bug#9545)
6739 2011-09-18 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
6741 * xdisp.c (expose_window): Save original value of phys_cursor_on_p
6742 and turn window cursor on if cleared (Bug#9415).
6744 2011-09-18 Andreas Schwab <schwab@linux-m68k.org>
6746 * search.c (boyer_moore): Take unibyte characters from pattern
6747 literally. (Bug#9458)
6749 2011-09-18 Eli Zaretskii <eliz@gnu.org>
6751 * xdisp.c (reseat_at_next_visible_line_start): Fix last change.
6753 2011-09-18 Paul Eggert <eggert@cs.ucla.edu>
6755 Fix minor problem found by static checking.
6756 * xdisp.c (reseat_at_next_visible_line_start): Mark locals as
6757 initialized, to pacify gcc -Wuninitialized.
6759 * fileio.c: Report proper errno when syscall falls.
6760 (Finsert_file_contents): Save and restore errno,
6761 so that report_file_error outputs the correct diagnostic.
6762 (Fwrite_region) [CLASH_DETECTION]: Likewise.
6764 2011-09-18 Eli Zaretskii <eliz@gnu.org>
6766 * .gdbinit (pgx): Fix references to fields of `struct glyph'.
6768 2011-09-17 Eli Zaretskii <eliz@gnu.org>
6770 * xdisp.c (produce_stretch_glyph): Another fix for changes made on
6771 2011-08-30 (revision 105619). (Bug#9530)
6773 2011-09-17 Eli Zaretskii <eliz@gnu.org>
6775 * xdisp.c (reseat_at_next_visible_line_start): Keep information
6776 about the current paragraph and restore it after the call to reseat.
6778 * bidi.c (MAX_PARAGRAPH_SEARCH): New macro.
6779 (bidi_find_paragraph_start): Search back for paragraph beginning
6780 at most MAX_PARAGRAPH_SEARCH lines; if not found, return BEGV_BYTE.
6781 (bidi_move_to_visually_next): Only trigger paragraph-related
6782 computations when the last character is a newline or at EOB, not
6783 just any NEUTRAL_B. (Bug#9470)
6785 * xdisp.c (set_cursor_from_row): Don't invoke special treatment of
6786 truncated lines if point is covered by a display string. (Bug#9524)
6788 2011-09-16 Paul Eggert <eggert@cs.ucla.edu>
6790 * xselect.c: Relax test for outgoing X longs (Bug#9498).
6791 (cons_to_x_long): New function.
6792 (lisp_data_to_selection_data): Use it. Correct the test for
6793 short-versus-long data; it was negated. Break out of vector
6794 loop, for efficiency, when a long datum is discovered.
6796 2011-09-16 Stefan Monnier <monnier@iro.umontreal.ca>
6798 * eval.c (Fquote): Document its non-consing behavior (bug#9482).
6800 2011-09-16 Eli Zaretskii <eliz@gnu.org>
6802 * image.c (tiff_handler): Work around a bug in MinGW GCC 3.x (see
6803 GCC PR/17406) by declaring this function with external scope.
6805 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
6807 * editfns.c (Fformat): Fix bug in text-property fix (Bug#9514).
6808 Don't mishandle (length (format "%%")) and (format "%4000s%%" "").
6810 2011-09-15 Andreas Schwab <schwab@linux-m68k.org>
6812 * editfns.c (Fformat): Correctly handle text properties on "%%".
6814 2011-09-15 Eli Zaretskii <eliz@gnu.org>
6816 * xterm.c (x_draw_composite_glyph_string_foreground):
6817 * w32term.c (x_draw_composite_glyph_string_foreground):
6818 * term.c (encode_terminal_code):
6819 * composite.c (composition_update_it, get_composition_id):
6820 * xdisp.c (get_next_display_element)
6821 (fill_composite_glyph_string): Add comments about special meaning
6822 of TAB characters in a composition.
6824 2011-09-15 Paul Eggert <eggert@cs.ucla.edu>
6826 * editfns.c (Fformat): Fix off-by-1 bug for "%%b" (Bug#9514).
6827 This occurs when processing a multibyte format.
6828 Problem reported by Wolfgang Jenker.
6830 2011-09-15 Johan Bockgård <bojohan@gnu.org>
6832 * xdisp.c (try_cursor_movement): Only check for exact match if
6833 cursor hpos found by set_cursor_from_row is valid. (Bug#9495)
6835 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
6837 Remove unused external symbols.
6838 * dispextern.h (calc_pixel_width_or_height): Remove decl.
6839 * xdisp.c (calc_pixel_width_or_height): Now static.
6840 * doprnt.c (exprintf) [! (HAVE_X_WINDOWS && USE_X_TOOLKIT)]: Remove.
6841 * indent.c (check_display_width):
6842 * w32term.c: Fix comment to match code.
6843 * xterm.c, xterm.h (x_catching_errors): Remove.
6845 2011-09-14 Paul Eggert <eggert@cs.ucla.edu>
6847 * xselect.c: Use signed conversions more consistently (Bug#9498).
6848 (selection_data_to_lisp_data): Assume incoming selection data are
6849 signed integers, not unsigned. This is to be consistent with
6850 outgoing selection data, which was modified to use signed integers
6851 in as part of the fix to Bug#9196 in response to Jan D.'s comment
6852 in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9196#32> that X11
6853 expects long, not unsigned long.
6855 2011-09-14 Eli Zaretskii <eliz@gnu.org>
6857 * xdisp.c (try_window_reusing_current_matrix): Fix incorrect
6858 computation of loop end. Reported by Johan Bockgård
6859 <bojohan@gnu.org>.
6861 2011-09-13 Chong Yidong <cyd@stupidchicken.com>
6863 * frame.c (Fother_visible_frames_p): Function deleted.
6865 2011-09-12 Eli Zaretskii <eliz@gnu.org>
6867 * indent.c (compute_motion): Process display vector front to back
6868 rather than the other way around. (Bug#2496)
6870 2011-09-12 Stefan Monnier <monnier@iro.umontreal.ca>
6872 * fileio.c (Finsert_file_contents): Don't assume beg_offset is 0.
6874 2011-09-11 Chong Yidong <cyd@stupidchicken.com>
6876 * minibuf.c (Fread_from_minibuffer): Doc fix.
6878 2011-09-11 Eli Zaretskii <eliz@gnu.org>
6880 * xdisp.c (produce_stretch_glyph): Fix a typo made in changes from
6881 2011-08-30 (revision 105619). (Bug#9475)
6883 2011-09-11 Lars Magne Ingebrigtsen <larsi@gnus.org>
6885 * fileio.c (Fvisited_file_modtime): Document `(-1 65535)' as a
6886 value for non-existent files.
6888 2011-09-11 Eli Zaretskii <eliz@gnu.org>
6890 * fileio.c (Finsert_file_contents): If the file cannot be opened,
6891 set its "size" to -1. This will set the modtime_size field of
6892 the corresponding buffer to -1, which is what
6893 verify-visited-file-modtime expects for files that do not exist.
6894 (Bug#9139)
6896 2011-09-11 Paul Eggert <eggert@cs.ucla.edu>
6898 * keymap.h (KEY_DESCRIPTION_SIZE, push_key_description): Move decls
6899 here ...
6900 * lisp.h: ... from here. push_key_description is no longer
6901 defined in keyboard.c, so its declaration should not be in
6902 lisp.h's "Defined in keyboard.c" section, and KEY_DESCRIPTION_SIZE
6903 logically belongs with push_key_description.
6905 2011-09-10 Paul Eggert <eggert@cs.ucla.edu>
6907 * buffer.h: Include <sys/types.h> instead of <time.h>.
6908 Otherwise, off_t wasn't defined on FreeBSD 9.0-BETA2 i386.
6909 Problem reported by Herbert J. Skuhra.
6911 2011-09-10 Lars Magne Ingebrigtsen <larsi@gnus.org>
6913 * xml.c (parse_region): Make the parsing work for
6914 non-comment-starting XML files again (bug#9144).
6916 2011-09-10 Andreas Schwab <schwab@linux-m68k.org>
6918 * image.c (gif_load): Fix calculation of bottom and right corner.
6919 (Bug#9468)
6921 2011-09-10 Eli Zaretskii <eliz@gnu.org>
6923 * xdisp.c (MAX_DISP_SCAN): Decrease to 250. Prevents sluggish
6924 redisplay in small windows.
6926 2011-09-09 Eli Zaretskii <eliz@gnu.org>
6928 * frame.c (x_report_frame_params): Cast to avoid compiler warnings.
6930 2011-09-08 Martin Rudalics <rudalics@gmx.at>
6932 * window.c (Fset_window_prev_buffers, Fset_window_next_buffers):
6933 Operate on live windows only.
6935 2011-09-08 Juanma Barranquero <lekktu@gmail.com>
6937 * emacs.c (my_heap_start): #ifdef to avoid warnings when unused.
6939 2011-09-07 Eli Zaretskii <eliz@gnu.org>
6941 * xdisp.c (move_it_in_display_line_to): Call RESTORE_IT on ppos_it
6942 only under bidi iteration.
6944 2011-09-07 Jan Djärv <jan.h.d@swipnet.se>
6946 * gtkutil.c (xg_make_tool_item): Insert comment about eventbox.
6948 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
6950 isnan: Fix porting problem to Solaris 10 with bundled gcc.
6951 Without this fix, the command to link temacs failed due to an
6952 undefined symbol __builtin_isnan. This is because
6953 /usr/include/iso/math_c99.h #defines isnan(x) to
6954 __builtin_isnan(x), but the bundled gcc, which identifies itself
6955 as gcc 3.4.3 (csl-sol210-3_4-branch+sol_rpath), does not have
6956 a __builtin_isnan.
6957 * floatfns.c (isnan): #undef, and then #define to a clone of
6958 what's in data.c.
6959 (Fisnan): Always define, since it's always available now.
6960 (syms_of_floatfns): Always define isnan at the Lisp level.
6962 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
6964 * Makefile.in (gl-stamp): move-if-change now in build-aux (Bug#9169).
6966 2011-09-06 Paul Eggert <eggert@cs.ucla.edu>
6968 * fileio.c: Fix bugs with large file offsets (Bug#9428).
6969 The previous code assumed that file offsets (off_t values) fit in
6970 EMACS_INT variables, which is not true on typical 32-bit hosts.
6971 The code messed up by falsely reporting buffer overflow in cases
6972 such as (insert-file-contents "big" nil 1 2) into an empty buffer
6973 when "big" contains more than 2**29 bytes, even though this
6974 inserts just one byte and does not overflow the buffer.
6975 (Finsert_file_contents): Store file offsets as off_t
6976 values, not as EMACS_INT values. Check for overflow when
6977 converting between EMACS_INT and off_t. When checking for
6978 buffer overflow or for overlap, take the offsets into account.
6979 Don't use EMACS_INT for small values where int suffices.
6980 When checking for overlap, fix a typo: ZV was used where
6981 ZV_BYTE was intended.
6982 (Fwrite_region): Don't assume off_t fits into 'long'.
6983 * buffer.h (struct buffer.modtime_size): Now off_t, not EMACS_INT.
6985 2011-09-05 Michael Albinus <michael.albinus@gmx.de>
6987 * dbusbind.c (xd_signature_cat): Rename from signature_cat.
6989 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
6991 sprintf-related integer and memory overflow issues (Bug#9412).
6993 * doprnt.c (doprnt): Support printing ptrdiff_t and intmax_t values.
6994 (esprintf, exprintf, evxprintf): New functions.
6995 * keyboard.c (command_loop_level): Now EMACS_INT, not int.
6996 (cmd_error): Kbd macro iterations count is now EMACS_INT, not int.
6997 (modify_event_symbol): Do not assume that the length of
6998 name_alist_or_stem is safe to alloca and fits in int.
6999 (Fexecute_extended_command): Likewise for function name and binding.
7000 (Frecursion_depth): Wrap around reliably on integer overflow.
7001 * keymap.c (push_key_description): First arg is now EMACS_INT, not int,
7002 since some callers pass EMACS_INT values.
7003 (Fsingle_key_description): Don't crash if symbol name contains more
7004 than MAX_ALLOCA bytes.
7005 * minibuf.c (minibuf_level): Now EMACS_INT, not int.
7006 (get_minibuffer): Arg is now EMACS_INT, not int.
7007 * lisp.h (get_minibuffer, push_key_description): Reflect API changes.
7008 (esprintf, exprintf, evxprintf): New decls.
7009 * window.h (command_loop_level, minibuf_level): Reflect API changes.
7011 * dbusbind.c (signature_cat): New function.
7012 (xd_signature, Fdbus_register_signal):
7013 Do not overrun buffer; instead, report string overflow.
7015 * dispnew.c (add_window_display_history): Don't overrun buffer.
7016 Truncate instead; this is OK since it's just a log.
7018 * editfns.c (Fcurrent_time_zone): Don't overrun buffer
7019 even if the time zone offset is outlandishly large.
7020 Don't mishandle offset == INT_MIN.
7022 * emacs.c (main) [NS_IMPL_COCOA]: Don't overrun buffer
7023 when creating daemon; the previous buffer-overflow check was incorrect.
7025 * eval.c (verror): Simplify by rewriting in terms of evxprintf,
7026 which has the guts of the old verror function.
7028 * filelock.c (lock_file_1, lock_file): Don't blindly alloca long name;
7029 use SAFE_ALLOCA instead. Use esprintf to avoid int-overflow issues.
7031 * font.c: Include <float.h>, for DBL_MAX_10_EXP.
7032 (font_unparse_xlfd): Don't blindly alloca long strings.
7033 Don't assume XINT result fits in int, or that XFLOAT_DATA * 10
7034 fits in int, when using sprintf. Use single snprintf to count
7035 length of string rather than counting it via multiple sprintfs;
7036 that's simpler and more reliable.
7037 (font_unparse_fcname): Use it to avoid sprintf buffer overrun.
7038 (generate_otf_features) [0 && HAVE_LIBOTF]: Use esprintf, not
7039 sprintf, in case result does not fit in int.
7041 * fontset.c (num_auto_fontsets): Now printmax_t, not int.
7042 (fontset_from_font): Print it.
7044 * frame.c (tty_frame_count): Now printmax_t, not int.
7045 (make_terminal_frame, set_term_frame_name): Print it.
7046 (x_report_frame_params): In X, window IDs are unsigned long,
7047 not signed long, so print them as unsigned.
7048 (validate_x_resource_name): Check for implausibly long names,
7049 and don't assume name length fits in 'int'.
7050 (x_get_resource_string): Don't blindly alloca invocation name;
7051 use SAFE_ALLOCA. Use esprintf, not sprintf, in case result does
7052 not fit in int.
7054 * gtkutil.c: Include <float.h>, for DBL_MAX_10_EXP.
7055 (xg_check_special_colors, xg_set_geometry):
7056 Make sprintf buffers a bit bigger, to avoid potential buffer overrun.
7058 * lread.c (dir_warning): Don't blindly alloca buffer; use SAFE_ALLOCA.
7059 Use esprintf, not sprintf, in case result does not fit in int.
7061 * macros.c (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7062 (Fend_kbd_macro): Don't mishandle MOST_NEGATIVE_FIXNUM by treating
7063 it as a large positive number.
7064 (Fexecute_kbd_macro): Don't assume repeat count fits in int.
7065 * macros.h (executing_kbd_macro_iterations): Now EMACS_INT, not int.
7067 * nsterm.m ((NSSize)windowWillResize): Use esprintf, not sprintf,
7068 in case result does not fit in int.
7070 * print.c (float_to_string): Detect width overflow more reliably.
7071 (print_object): Make sprintf buffer a bit bigger, to avoid potential
7072 buffer overrun. Don't assume list length fits in 'int'. Treat
7073 print length of 0 as 0, not as infinity; to be consistent with other
7074 uses of print length in this function. Don't overflow print length
7075 index. Don't assume hash table size fits in 'long', or that
7076 vectorlike size fits in 'unsigned long'.
7078 * process.c (make_process): Use printmax_t, not int, to format
7079 process-name gensyms.
7081 * sysdep.c (snprintf) [! HAVE_SNPRINTF]: New function.
7083 * term.c (produce_glyphless_glyph): Make sprintf buffer a bit bigger
7084 to avoid potential buffer overrun.
7086 * xfaces.c (x_update_menu_appearance): Don't overrun buffer
7087 if X resource line is longer than 512 bytes.
7089 * xfns.c (x_window): Make sprintf buffer a bit bigger
7090 to avoid potential buffer overrun.
7092 * xterm.c (x_io_error_quitter): Don't overrun sprintf buffer.
7094 * xterm.h (x_check_errors): Add ATTRIBUTE_FORMAT_PRINTF.
7096 2011-09-04 Paul Eggert <eggert@cs.ucla.edu>
7098 Integer overflow fixes for scrolling, etc.
7099 Without these, Emacs silently mishandles large integers sometimes.
7100 For example, "C-u 4294967297 M-x recenter" was treated as if
7101 it were "C-u 1 M-x recenter" on a typical 64-bit host.
7103 * xdisp.c (try_window_id): Check Emacs fixnum range before
7104 converting to 'int'.
7106 * window.c (window_scroll_line_based, Frecenter):
7107 Check that an Emacs fixnum is in range before assigning it to 'int'.
7108 (Frecenter, Fmove_to_window_line): Use EMACS_INT, not int, for
7109 values converted from Emacs fixnums.
7110 (Frecenter): Don't wrap around a line count if it is out of 'int'
7111 range; instead, treat it as an extreme value.
7112 (Fset_window_configuration, compare_window_configurations):
7113 Use ptrdiff_t, not int, for index that might exceed 2 GiB.
7115 * search.c (Freplace_match): Use ptrdiff_t, not int, for indexes
7116 that can exceed INT_MAX. Check that EMACS_INT value is in range
7117 before assigning it to the (possibly-narrower) index.
7118 (match_limit): Don't assume that a fixnum can fit in 'int'.
7120 * print.c (print_object): Use ptrdiff_t, not int, for index that can
7121 exceed INT_MAX.
7123 * indent.c (position_indentation): Now takes ptrdiff_t, not int.
7124 (Fvertical_motion): Don't wrap around LINES values that don't fit
7125 in 'int'. Instead, treat them as extreme values. This is good
7126 enough for windows, which can't have more than INT_MAX lines anyway.
7128 2011-09-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
7130 * Require libxml/parser.h to avoid compilation warning.
7132 * emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.
7134 * xml.c (parse_region): Don't call xmlCleanupParser after parsing,
7135 since this reportedly can destroy thread storage.
7137 2011-08-30 Chong Yidong <cyd@stupidchicken.com>
7139 * syntax.c (find_defun_start): Update all cache variables if
7140 exiting early (Bug#9401).
7142 2011-08-30 Eli Zaretskii <eliz@gnu.org>
7144 * image.c (x_bitmap_pixmap): Cast to int to avoid compiler warnings.
7146 * xdisp.c (produce_stretch_glyph): No longer static, compiled also
7147 when HAVE_WINDOW_SYSTEM is not defined. Support both GUI and TTY
7148 frames. Call tty_append_glyph in the TTY case. (Bug#9402)
7150 * term.c (tty_append_glyph): New function.
7151 (produce_stretch_glyph): Static function and its prototype deleted.
7153 * dispextern.h (produce_stretch_glyph, tty_append_glyph):
7154 Add prototypes.
7156 2011-08-29 Paul Eggert <eggert@cs.ucla.edu>
7158 * image.c (parse_image_spec): Check for nonnegative, not for positive,
7159 when checking :margin (Bug#9390).
7160 (IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
7161 Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
7162 so that the name doesn't mislead. All uses changed.
7164 2011-08-28 Johan Bockgård <bojohan@gnu.org>
7166 * term.c (init_tty) [HAVE_GPM]: Move mouse settings after
7167 set_tty_hooks.
7169 2011-08-27 Eli Zaretskii <eliz@gnu.org>
7171 * xdisp.c (move_it_to): Don't bail out early when reaching
7172 position beyond to_charpos, if we are scanning backwards.
7173 (move_it_vertically_backward): When DY == 0, make sure we get to
7174 the first character in the line after the newline.
7176 2011-08-27 Paul Eggert <eggert@cs.ucla.edu>
7178 * ccl.c: Improve and simplify overflow checking (Bug#9196).
7179 (ccl_driver): Do not generate an out-of-range pointer.
7180 (Fccl_execute_on_string): Remove unnecessary check for
7181 integer overflow, noted by Stefan Monnier in
7182 <http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
7183 Remove a FIXME that didn't need fixing.
7184 Simplify the newly-introduced buffer reallocation code.
7186 2011-08-27 Juanma Barranquero <lekktu@gmail.com>
7188 * makefile.w32-in ($(BLD)/alloc.$(O)): Depend on lib/verify.h.
7190 2011-08-26 Paul Eggert <eggert@cs.ucla.edu>
7192 Integer and memory overflow issues (Bug#9196).
7194 * doc.c (get_doc_string): Rework so that
7195 get_doc_string_buffer_size is the actual buffer size, rather than
7196 being 1 less than the actual buffer size; this makes xpalloc more
7197 convenient.
7199 * image.c (x_allocate_bitmap_record, cache_image):
7200 * xselect.c (Fx_register_dnd_atom):
7201 Simplify previous changes by using xpalloc.
7203 * buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
7204 since either will do and ptrdiff_t is convenient with xpalloc.
7206 * charset.c (charset_table_size)
7207 (struct charset_sort_data.priority): Now ptrdiff_t.
7208 (charset_compare): Don't overflow if priorities differ greatly.
7209 (Fsort_charsets): Don't assume list length fits in int.
7210 Check for size-calculation overflow when allocating sort data.
7211 (syms_of_charset): Allocate an initial charset table that is
7212 just under 64 KiB, to avoid problems with glibc malloc and mmap.
7214 * cmds.c (internal_self_insert): Check for size-calculation overflow.
7216 * composite.h (struct composition.glyph_len): Now int, not unsigned.
7217 The actual value is always <= INT_MAX, and leaving it unsigned made
7218 overflow checking harder.
7220 * dispextern.h (struct glyph_matrix.rows_allocated)
7221 (struct face_cache.size): Now ptrdiff_t, for convenience in use
7222 with xpalloc. The values are still always <= INT_MAX.
7224 * indent.c (compute_motion): Adjust to region_cache_forward sig change.
7226 * lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
7227 (SAFE_NALLOCA): New macro.
7229 * region-cache.c (struct boundary.pos, find_cache_boundary)
7230 (move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
7231 (set_cache_region, invalidate_region_cache)
7232 (revalidate_region_cache, know_region_cache, region_cache_forward)
7233 (region_cache_backward, pp_cache):
7234 Use ptrdiff_t, not EMACS_INT, since either will do. This is needed
7235 so that ptrdiff_t * can be passed to xpalloc.
7236 (struct region_cache): Similarly, for gap_start, gap_len, cache_len,
7237 beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
7238 (pp_cache): Don't assume cache_len fits in int.
7239 * region-cache.h: Adjust extern decls to match.
7241 * search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
7242 EMACS_INT, since either will do, for xpalloc.
7244 * alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
7245 (xnmalloc, xnrealloc, xpalloc): New functions.
7247 * bidi.c (bidi_shelve_header_size): New constant.
7248 (bidi_cache_ensure_space, bidi_shelve_cache): Use it.
7249 (bidi_cache_ensure_space): Avoid integer overflow when allocating.
7251 * bidi.c (bidi_cache_shrink):
7252 * buffer.c (overlays_at, overlays_in, record_overlay_string)
7253 (overlay_strings):
7254 Don't update size of array until after memory allocation succeeds,
7255 because xmalloc/xrealloc may not return.
7256 (struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
7257 now that we have proper integer overflow checking.
7258 (record_overlay_string, overlay_strings): Catch overflows when
7259 calculating size of overlay_str_buf.
7261 * callproc.c (Fcall_process): Check for size overflow when
7262 calculating size of args2.
7263 (child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
7264 Normally we prefer signed values, but sticking with ptrdiff_t would
7265 require adding more-complicated checks.
7267 * ccl.c (Fccl_execute_on_string): Check for memory overflow.
7268 Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
7269 Redo buffer-overflow calculations to avoid integer overflow.
7270 Add a FIXME comment where memory seems to be over-allocated.
7272 * character.c (Fstring): Check for size-calculation overflow.
7274 * coding.c (produce_chars): Redo buffer-overflow calculations to avoid
7275 unnecessary integer overflow. Check for size overflow.
7276 (encode_coding_object): Don't update size until xmalloc succeeds.
7278 * composite.c (get_composition_id): Check for overflow in glyph
7279 length calculations.
7281 Integer and memory overflow fixes for display code.
7282 * dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.
7283 * dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
7284 (scrolling_window): Check for overflow in size calculations.
7285 (line_draw_cost, realloc_glyph_pool, add_row_entry):

7297 (get_doc_string): Check for size calculation overflow.
7298 Don't update size until allocation succeeds.
7299 (get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
7300 EMACS_INT, where ptrdiff_t will do.
7301 (Fsubstitute_command_keys): Check for string overflow.
7303 * editfns.c (set_time_zone_rule): Don't assume environment length
7304 fits in int.
7305 (message_length): Now ptrdiff_t, not int.
7306 (Fmessage_box): Don't update size until allocation succeeds.
7307 Don't assume message length fits in int.
7308 (Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.
7310 * emacs.c (main): Do not reallocate argv, since there is a null at
7311 the end that can be overwritten, and this way there's no need to
7312 worry about size-calculation overflow.
7313 (sort_args): Check for size-calculation overflow.
7315 * eval.c (init_eval_once, grow_specpdl): Don't update size until
7316 alloc succeeds.
7317 (call_debugger, grow_specpdl): Redo calculations to avoid overflow.
7319 * frame.c (set_menu_bar_lines, x_set_frame_parameters)
7320 (x_set_scroll_bar_width, x_figure_window_size):
7321 Check for integer overflow.
7322 (x_set_alpha): Do not assume XINT fits in int.
7324 * frame.h (struct frame): Use int, not EMACS_INT, where int works.
7325 This is for the members text_lines, text_cols, total_lines, total_cols,
7326 where the system imposes an 'int' limit.
7328 * fringe.c (Fdefine_fringe_bitmap):
7329 Don't update size until alloc works.
7331 * ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
7332 (ftfont_shape_by_flt): Check for integer overflow in size calculations.
7334 * gtkutil.c (get_utf8_string, xg_store_widget_in_map):
7335 Check for size-calculation overflow.
7336 (get_utf8_string): Use ptrdiff_t, not size_t, where either will
7337 do, as we prefer signed integers.
7338 (id_to_widget.max_size, id_to_widget.used)
7339 (xg_store_widget_in_map, xg_remove_widget_from_map)
7340 (xg_get_widget_from_map, xg_get_scroll_id_for_window)
7341 (xg_remove_scroll_bar, xg_update_scrollbar_pos):
7342 Use and return ptrdiff_t, not int.
7343 (xg_gtk_scroll_destroy): Don't assume ptrdiff_t fits in int.
7344 * gtkutil.h: Change prototypes to match the above.
7346 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): Remove; these
7347 are duplicate now that they've been promoted to lisp.h.
7348 (x_allocate_bitmap_record, x_alloc_image_color)
7349 (make_image_cache, cache_image, xpm_load):
7350 Don't update size until alloc is done.

7360 (read_char_minibuf_menu_prompt, follow_key, read_key_sequence):
7361 Use ptrdiff_t, not int, to count maps.
7362 (read_char_minibuf_menu_prompt): Check for overflow in size
7363 calculations. Don't update size until allocation succeeds.

7374 * macros.c (Fstart_kbd_macro): Don't update size until alloc done.
7375 (store_kbd_macro_char): Reorder multiplicands to avoid overflow.

7391 (Fset_match_data): Don't assume list lengths fit in 'int'.
7393 * sysdep.c (system_process_attributes): Use ptrdiff_t, not int,
7394 for command line length. Do not attempt to address one before the
7395 beginning of an array, as that's not portable.
7397 * term.c (max_frame_lines): Remove; unused.
7398 (encode_terminal_src_size, encode_terminal_dst_size): Now ptrdiff_t,
7399 not int.

7407 * termcap.c (tgetent): Use ptrdiff_t, not int, to record results of
7408 subtracting pointers.

7423 Use ptrdiff_t, not int, for sizes.
7424 (Finternal_make_lisp_face, cache_face):
7425 Check for size calculation overflow.
7426 (cache_face): Treat size calculation overflows as if they were
7427 memory exhaustion (the usual treatment), rather than aborting.
7429 * xfns.c (x_encode_text, x_set_name_internal)
7430 (Fx_change_window_property): Use ptrdiff_t, not int, to count
7431 sizes, since they can exceed INT_MAX in size. Check for size

7435 (xg_select): Check for size calculation overflow.
7436 Don't update size until alloc done.
7438 * xrdb.c (get_environ_db): Don't assume path length fits in int,

7441 * xselect.c (X_LONG_SIZE, X_SHRT_MAX, X_SHRT_MIN, X_LONG_MAX)
7442 (X_LONG_MIN): New macros.
7443 Use them to make the following changes clearer.
7444 (MAX_SELECTION_QUANTUM): Make the other bounds on this value clearer.
7445 This change doesn't affect the value now, but it may help remind
7446 future maintainers not to raise the value too much later.
7447 (SELECTION_QUANTUM): Remove, replacing with ...
7448 (selection_quantum): ... new function, which avoids overflow.
7449 All uses changed.
7450 (struct selection_data.size): Now ptrdiff_t, not int, to avoid
7451 assumption that selection length fits in 'int'.

7453 (x_get_window_property, receive_incremental_selection)
7454 (x_get_window_property_as_lisp_data, selection_data_to_lisp_data)
7455 (lisp_data_to_selection_data, clean_local_selection_data):

7459 Redo calculations to avoid overflow.
7460 (x_reply_selection_request): When sending hint, ceiling it at

7462 something.
7463 (x_get_window_property, receive_incremental_selection)
7464 (lisp_data_to_selection_data, x_property_data_to_lisp):
7465 Check for size-calculation overflow.

7468 Don't store size until memory allocation succeeds.
7469 (x_get_window_property): Plug memory leak on memory exhaustion.
7470 Don't double-block input; malloc is safe here. Don't assume 2**34
7471 - 4 fits in unsigned long. Add an xassert to check
7472 XGetWindowProperty overflow. Be more careful about overflow
7473 calculations, and distinguish size from memory overflow better.
7474 (receive_incremental_selection): When tracing, don't assume
7475 unsigned int is less than INT_MAX.
7476 (x_selection_data_to_lisp_data): Remove unnecessary (and in theory

7478 (lisp_data_to_selection_data): Don't assume that integers
7479 in the range -65535 through -1 fit in an X unsigned short.
7480 Don't assume that ULONG_MAX == X_ULONG_MAX. Don't store into
7481 result parameters unless successful. Rely on cons_to_unsigned
7482 to report problems with elements; the old code wasn't right anyway.
7483 (x_check_property_data): Check for int overflow; we cannot use
7484 a wider type due to X limits.
7485 (x_handle_dnd_message): Use unsigned int, to avoid int overflow.
7487 * xsmfns.c (smc_save_yourself_CB): Check for size calc overflow.

7516 * image.c (xpm_get_color_table_h):
7517 * lisp.h (hash_lookup, hash_put):
7518 * minibuf.c (Ftest_completion):
7519 Use ptrdiff_t for hash table indexes, not int (which is too
7520 narrow, on 64-bit hosts) or EMACS_INT (which is too wide, on
7521 32-bit --with-wide-int hosts).
7523 * charset.c (Fdefine_charset_internal): Check for integer overflow.
7524 Add a FIXME comment about memory leaks.
7525 (syms_of_charset): Don't assume xmalloc returns.
7527 Don't assume that stated character widths fit in int.
7528 * character.c (Fchar_width, c_string_width, lisp_string_width):
7529 * character.h (CHAR_WIDTH):
7530 * indent.c (MULTIBYTE_BYTES_WIDTH):
7531 Use sanitize_char_width to avoid undefined and/or bad behavior
7532 with outlandish widths.
7533 * character.h (sanitize_tab_width): Rename from sanitize_width,
7534 now that we have two such functions. All uses changed.
7535 (sanitize_char_width): New inline function.
7537 Don't assume that tab-width fits in int.
7538 * character.h (sanitize_width): New inline function.
7539 (SANE_TAB_WIDTH): New macro.

7541 * indent.c (sane_tab_width): Remove. All uses replaced by
7542 SANE_TAB_WIDTH (current_buffer).
7543 * xdisp.c (init_iterator): Use SANE_TAB_WIDTH.
7545 * fileio.c: Integer overflow issues with file modes.
7546 (Fset_file_modes, auto_save_1): Don't assume EMACS_INT fits in int.
7548 * charset.c (read_hex): New arg OVERFLOW. All uses changed.

7554 (x_send_scroll_bar_event): Likewise. Check that the size does not
7555 exceed limits imposed by XClientMessageEvent, as well as the usual
7556 ptrdiff_t and size_t limits.
7558 * keyboard.c: Overflow, signedness and related fixes.
7559 (make_lispy_movement): Use same integer type in forward decl
7560 that is used in the definition.
7561 (read_key_sequence, keyremap_step):
7562 Change bufsize argument back to int, undoing my 2011-03-30 change.
7563 We prefer signed types, and int is wide enough here.
7564 (parse_tool_bar_item): Don't assume tool_bar_max_label_size is less
7565 than TYPE_MAXIMUM (EMACS_INT) / 2. Don't let the label size grow
7566 larger than STRING_BYTES_BOUND. Use ptrdiff_t for Emacs string
7567 length, not size_t. Use ptrdiff_t for index, not int.
7568 (keyremap_step, read_key_sequence): Redo bufsize check to avoid
7569 possibility of integer overflow.
7571 Overflow, signedness and related fixes for images.
7573 * dispextern.h (struct it.stack[0].u.image.image_id)
7574 (struct_it.image_id, struct image.id, struct image_cache.size)
7575 (struct image_cache.used, struct image_cache.ref_count):
7576 * gtkutil.c (update_frame_tool_bar):
7577 * image.c (x_reference_bitmap, Fimage_size, Fimage_mask_p)
7578 (Fimage_metadata, free_image_cache, clear_image_cache, lookup_image)
7579 (cache_image, mark_image_cache, x_kill_gs_process, Flookup_image):
7580 * nsmenu.m (update_frame_tool_bar):
7581 * xdisp.c (calc_pixel_width_or_height):
7582 * xfns.c (image_cache_refcount):
7583 Image IDs are now ptrdiff_t, not int, to avoid arbitrary limits
7584 on typical 64-bit hosts.
7586 * image.c (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.
7587 (x_bitmap_pixmap, x_create_x_image_and_pixmap):
7588 Omit unnecessary casts to int.
7589 (parse_image_spec): Check that integers fall into 'int' range
7590 when the callers expect that.
7591 (image_ascent): Redo ascent calculation to avoid int overflow.
7592 (clear_image_cache): Avoid overflow when sqrt (INT_MAX) < nimages.
7593 (lookup_image): Remove unnecessary tests.
7594 (xbm_image_p): Locals are now of int, not EMACS_INT,
7595 since parse_image_check makes sure they fit into int.
7596 (png_load, gif_load, svg_load_image):
7597 Prefer int to unsigned where either will do.
7598 (tiff_handler): New function, combining the cores of the
7599 old tiff_error_handler and tiff_warning_handler.
7600 This function is rewritten to use vsnprintf and thereby avoid
7601 stack buffer overflows. It uses only the features of vsnprintf
7602 that are common to both POSIX and native Microsoft.
7603 (tiff_error_handler, tiff_warning_handler): Use it.
7604 (tiff_load, gif_load, imagemagick_load_image):
7605 Don't assume :index value fits in 'int'.
7606 (gif_load): Omit unnecessary cast to double, and avoid double-rounding.
7607 (imagemagick_load_image): Check that crop parameters fit into
7608 the integer types that MagickCropImage accepts. Don't assume
7609 Vimagemagick_render_type has a nonnegative value. Don't assume
7610 size_t fits in 'long'.
7611 (gs_load): Use printmax_t to print the widest integers possible.
7612 Check for integer overflow when computing image height and width.
7614 2011-08-26 Eli Zaretskii <eliz@gnu.org>
7616 * xdisp.c (redisplay_window): Don't force window start if point

7621 * xdisp.c (compute_display_string_pos): Return 2 in DISP_PROP when
7622 the display spec is of the form `(space ...)'.
7623 (handle_display_spec): Return the value returned by
7624 handle_single_display_spec, not just 1 or zero.
7625 (handle_single_display_spec): If the display spec is of the form
7626 `(space ...)', and specifies display in the text area, return 2
7627 rather than 1.
7628 (try_cursor_movement): Check for the need to scroll more
7629 accurately, and prefer exact match for point under bidi.
7630 Don't advance `row' beyond the last row of the window.
7632 * dispextern.h (struct bidi_it): Rename the disp_prop_p member
7633 into disp_prop; all users changed.
7635 * bidi.c (bidi_fetch_char): If compute_display_string_pos returns
7636 DISP_PROP = 2, substitute the u+2029 PARAGRAPH SEPARATOR character
7637 for the text covered by the display property.

7647 * xdisp.c (Fcurrent_bidi_paragraph_direction): For unibyte
7648 buffers, return left-to-right.
7649 (set_cursor_from_row): Consider candidate row a win if its glyph
7650 represents a newline and point is on that newline. Fixes cursor
7651 positioning on the newline at EOL of R2L text within L2R
7652 paragraph, and vice versa.
7653 (try_cursor_movement): Check continued rows, in addition to
7654 continuation rows. Fixes unwarranted scroll when point enters a
7655 continued line of R2L text within an L2R paragraph, or vice versa.
7656 (cursor_row_p): Consider the case of point being equal to
7657 MATRIX_ROW_END_CHARPOS. Prevents cursor being stuck when moving
7658 from the end of a short line to the beginning of a continued line
7659 of R2L text within L2R paragraph.
7660 (RECORD_MAX_MIN_POS): For max_pos, use IT_CHARPOS even for
7661 composed characters.

7670 a character.
7672 2011-08-23 Chong Yidong <cyd@stupidchicken.com>
7674 * nsfont.m (ns_otf_to_script): Fix typo.
7676 2011-08-22 Kenichi Handa <handa@m17n.org>
7678 * chartab.c (Fset_char_table_extra_slot): Do not inhibit setting a
7679 extra slot even if the purpose is char-code-property-table.
7681 2011-08-23 Eli Zaretskii <eliz@gnu.org>
7683 * xdisp.c (redisplay_window): When computing centering_position,
7684 account for the height of the header line. (Bug#8874)
7686 * dispnew.c (buffer_posn_from_coords): Use buf_charpos_to_bytepos
7687 instead of CHAR_TO_BYTE. Fixes a crash when a completion
7688 candidate is selected by the mouse, and that candidate has a
7689 composed character under the mouse.
7691 * xdisp.c (x_produce_glyphs): Set it->nglyphs to 1. Fixes pixel
7692 coordinates reported by pos-visible-in-window-p for a composed
7693 character in column zero.
7695 2011-08-23 Stefan Monnier <monnier@iro.umontreal.ca>

7699 2011-08-22 Eli Zaretskii <eliz@gnu.org>
7701 * xdisp.c (BUFFER_POS_REACHED_P): If this is a composition,
7702 consider it a hit if to_charpos is anywhere in the range of the
7703 composed buffer positions.
7705 2011-08-22 Chong Yidong <cyd@stupidchicken.com>
7707 * image.c (gif_load): Don't assume that each subimage has the same
7708 dimensions as the base image. Handle disposal method that is
7709 "undefined" by the gif spec (Bug#9335).
7711 2011-08-20 Chong Yidong <cyd@stupidchicken.com>
7713 * eval.c (Fsignal): Handle `debug' symbol in error handler (Bug#9329).
7714 (Fcondition_case): Document `debug' symbol in error handler.
7716 2011-08-19 Eli Zaretskii <eliz@gnu.org>
7718 * xfaces.c (face_at_buffer_position): Avoid repeated evaluation of
7719 face ID by FACE_FROM_ID, and avoid a crash when mouse is moved
7720 from an Org mode buffer to a Speedbar frame.
7722 * xdisp.c (RECORD_MAX_MIN_POS): If the display element comes from
7723 a composition, take its buffer position from IT->cmp_it.charpos.
7724 Fixes cursor positioning at the beginning of a line that begins
7725 with a composed character.
7727 2011-08-18 Eli Zaretskii <eliz@gnu.org>
7729 * bidi.c (bidi_get_type): If bidi_type_table reports zero as the
7730 character bidirectional type, use STRONG_L instead. Fixes crashes
7731 in a buffer produced by `describe-categories'.
7733 * dispextern.h (struct bidi_it): Move disp_pos and disp_prop_p
7734 members before the level stack, so they would be saved and
7735 restored when copying iterator state. Fixes incorrect reordering
7736 around TABs covered by display properties.
7738 2011-08-18 Andreas Schwab <schwab@linux-m68k.org>
7740 * process.c (Fnetwork_interface_list): Correctly determine buffer size.

7748 2011-08-17 Eli Zaretskii <eliz@gnu.org>
7750 * lread.c (Fload) [DOS_NT]: If `openp' returns -2, but the file
7751 has no `load' handler, try opening the file locally. (Bug#9311)
7753 2011-08-16 Ken Brown <kbrown@cornell.edu>
7755 * gmalloc.c: Expand comment.
7757 2011-08-16 Eli Zaretskii <eliz@gnu.org>

7824 the event loop. Get status from as_status (Bug#7276).
7826 * nsterm.m (sendEvent): If event is NSApplicationDefined and
7827 data2 is NSAPP_DATA2_RUNASSCRIPT, call ns_run_ascript and then exit
7828 the event loop (Bug#7276).
7830 2011-08-14 Andreas Schwab <schwab@linux-m68k.org>

7867 when IT->position is set up wrongly due to some bug.
7868 Set IT->current to match the bidi iterator unconditionally.
7869 (push_display_prop): Allow GET_FROM_STRING as IT->method on
7870 entry. Force push_it to save on the stack the current
7871 buffer/string position, to be restored by pop_it. Fix flags in
7872 the iterator structure wrt the object coming from a display
7873 property, as `line-prefix' and `wrap-prefix' are not ``replacing''
7874 properties. (Bug#9284)
7876 2011-08-09 Andreas Schwab <schwab@linux-m68k.org>
7878 * fontset.c (fontset_get_font_group): Add proper type checks.

7917 longlines-mode. (Bug#9254)
7918 (move_it_in_display_line_to): Fix vertical-motion in a buffer with
7919 word-wrap under bidirectional display. (Bug#9224)
7921 * bidi.c (bidi_unshelve_cache): Don't reset the cache if JUST_FREE
7922 is non-zero, even if the data buffer is NULL. Fixes a crash in
7923 vertical-motion with longlines-mode. (Bug#9254)
7925 2011-08-05 Eli Zaretskii <eliz@gnu.org>
7927 * bidi.c <bidi_cache_total_alloc>: Now static.
7928 (bidi_initialize): Initialize bidi_cache_total_alloc.

7931 cache. (Bug#9221)
7933 * bidi.c (bidi_shelve_cache, bidi_unshelve_cache): Track total
7934 amount allocated this far in `bidi_cache_total_alloc'.
7935 (bidi_unshelve_cache): Accept an additional argument JUST_FREE; if

7937 contents. All callers changed.
7939 * dispextern.h (bidi_unshelve_cache): Update prototype.
7941 * xdisp.c (SAVE_IT, pos_visible_p, move_it_in_display_line_to)

8047 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8049 * nsfns.m (x_set_foreground_color): Set f->foreground_pixel when
8050 setting frame foreground color (Bug#9175).
8051 (x_set_background_color): Likewise.
8053 * nsmenu.m (-setText): Size tooltip dimensions precisely to
8054 contents (Bug#9176).
8055 (EmacsTooltip -init): Remove bezels and add shadows to
8056 tooltip windows.
8058 * nsterm.m (ns_dumpglyphs_stretch): Avoid overwriting left fringe
8059 or scroll bar (Bug#8470).
8061 * nsfont.m (nsfont_open): Remove assignment to voffset and
8062 unnecessary vars hshink, expand, hd, full_height, min_height.
8063 (nsfont_draw): Use s->ybase as baseline for glyph drawing (Bug#8913).
8065 * nsterm.h (nsfont_info): Remove voffset field.
8067 2011-07-28 Alp Aker <alp.tekin.aker@gmail.com>
8069 Implement strike-through and overline on NextStep (Bug#8863).
8071 * nsfont.m (nsfont_open): Use underline position provided by font,
8072 instead of hard-coded value of 2.
8073 (nsfont_draw): Call ns_draw_text_decoration instead.
8075 * nsterm.h: Add declaration for ns_draw_text_decoration.
8077 * nsterm.m (ns_draw_text_decoration): New function for drawing
8078 underline, overline, and strike-through.
8079 (ns_dumpglyphs_image, ns_dumpglyphs_stretch): Add call to
8080 ns_draw_text_decoration. Change treatment of cursor drawing to
8081 accommodate underlining, etc.
8083 2011-07-28 Eli Zaretskii <eliz@gnu.org>
8085 * buffer.c (init_buffer_once): Set bidi-display-reordering to t by
8086 default.
8088 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8090 * alloc.c (memory_full) [!SYNC_INPUT]: Fix signal-related race.
8091 Without this fix, if a signal arrives just after memory fills up,
8092 'malloc' might be invoked reentrantly.
8094 * image.c (x_check_image_size) [!HAVE_X_WINDOWS]: Return 1.
8095 In other words, assume that every image size is allowed, on non-X
8096 hosts. This assumption is probably wrong, but it lets Emacs compile.
8098 2011-07-28 Andreas Schwab <schwab@linux-m68k.org>
8100 * regex.c (re_iswctype): Convert return values to boolean.
8102 2011-07-28 Eli Zaretskii <eliz@fencepost.gnu.org>
8104 * xdisp.c (compute_display_string_pos): Don't use cached display
8105 string position if the buffer had its restriction changed.
8106 (Bug#9184)
8108 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8110 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
8112 2011-07-28 Paul Eggert <eggert@cs.ucla.edu>
8114 Integer signedness and overflow and related fixes. (Bug#9079)
8116 * bidi.c: Integer size and overflow fixes.
8117 (bidi_cache_size, bidi_cache_idx, bidi_cache_last_idx)
8118 (bidi_cache_start, bidi_cache_fetch_state, bidi_cache_search)
8119 (bidi_cache_find_level_change, bidi_cache_ensure_space)
8120 (bidi_cache_iterator_state, bidi_cache_find, bidi_cache_start_stack)
8121 (bidi_find_other_level_edge):
8122 Use ptrdiff_t instead of EMACS_INT where either will do.
8123 This works better on 32-bit hosts configured --with-wide-int.
8124 (bidi_cache_ensure_space): Check for size-calculation overflow.
8125 Use % rather than repeated addition, for better worst-case speed.
8126 Don't set bidi_cache_size until after xrealloc returns, because it
8127 might not return.
8128 (bidi_dump_cached_states): Use ptrdiff_t, not int, to avoid overflow.
8129 (bidi_cache_ensure_space): Also check that the bidi cache size
8130 does not exceed that of the largest Lisp string or buffer. See Eli
8131 Zaretskii in <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#29>.
8133 * alloc.c (__malloc_size_t): Remove.
8134 All uses replaced by size_t. See Andreas Schwab's note
8135 <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=9079#8>.
8137 * image.c: Improve checking for integer overflow.
8138 (check_image_size): Assume that f is nonnull, since
8139 it is always nonnull in practice. This is one less thing to
8140 worry about when checking for integer overflow later.
8141 (x_check_image_size): New function, which checks for integer
8142 overflow issues inside X.
8143 (x_create_x_image_and_pixmap, xbm_read_bitmap_data): Use it.
8144 This removes the need for a memory_full check.
8145 (xbm_image_p): Rewrite to avoid integer multiplication overflow.
8146 (Create_Pixmap_From_Bitmap_Data, xbm_load): Use x_check_image_size.
8147 (xbm_read_bitmap_data): Change locals back to 'int', since
8148 their values must fit in 'int'.
8149 (xpm_load_image, png_load, tiff_load):
8150 Invoke x_create_x_image_and_pixmap earlier,
8151 to avoid much needless work if the image is too large.
8152 (tiff_load): Treat overly large images as if
8153 x_create_x_image_and_pixmap failed, not as malloc failures.
8154 (gs_load): Use x_check_image_size.
8156 * gtkutil.c: Omit integer casts.
8157 (xg_get_pixbuf_from_pixmap): Remove unnecessary cast.
8158 (xg_set_toolkit_scroll_bar_thumb): Rewrite to avoid need for cast.
8160 * image.c (png_load): Don't assume height * row_bytes fits in 'int'.
8162 * xfaces.c (Fbitmap_spec_p): Fix integer overflow bug.
8163 Without this fix, (bitmap-spec-p '(34359738368 1 "x"))
8164 would wrongly return t on a 64-bit host.
8166 * dispnew.c (init_display): Use *_RANGE_OVERFLOW macros.
8167 The plain *_OVERFLOW macros run afoul of GCC bug 49705
8168 <http://gcc.gnu.org/bugzilla/show_bug.cgi?id=49705>
8169 and therefore cause GCC to emit a bogus diagnostic in some cases.
8171 * image.c: Integer signedness and overflow and related fixes.
8172 This is not an exhaustive set of fixes, but it's time to
8173 record what I've got.
8174 (lookup_pixel_color, check_image_size): Remove redundant decls.
8175 (check_image_size): Don't assume that arbitrary EMACS_INT values
8176 fit in 'int', or that arbitrary 'double' values fit in 'int'.
8177 (x_alloc_image_color, x_create_x_image_and_pixmap, png_load)
8178 (tiff_load, imagemagick_load_image):
8179 Check for overflow in size calculations.
8180 (x_create_x_image_and_pixmap): Remove unnecessary test for
8181 xmalloc returning NULL; that can't happen.
8182 (xbm_read_bitmap_data): Don't assume sizes fit into 'int'.
8183 (xpm_color_bucket): Use better integer hashing function.
8184 (xpm_cache_color): Don't possibly over-allocate memory.
8185 (struct png_memory_storage, tiff_memory_source, tiff_seek_in_memory)
8186 (gif_memory_source):
8187 Use ptrdiff_t, not int or size_t, to record sizes.
8188 (png_load): Don't assume values greater than 2**31 fit in 'int'.
8189 (our_stdio_fill_input_buffer): Prefer ptrdiff_t to size_t when
8190 either works, as we prefer signed integers.
8191 (tiff_read_from_memory, tiff_write_from_memory):
8192 Return tsize_t, not size_t, since that's what the TIFF API wants.
8193 (tiff_read_from_memory): Don't fail simply because the read would
8194 go past EOF; instead, return a short read.
8195 (tiff_load): Omit no-longer-needed casts.
8196 (Fimagemagick_types): Don't assume size fits into 'int'.
8198 Improve hashing quality when configured --with-wide-int.
8199 * fns.c (hash_string): New function, taken from sxhash_string.
8200 Do not discard information about ASCII character case; this
8201 discarding is no longer needed.
8202 (sxhash-string): Use it. Change sig to match it. Caller changed.
8203 * lisp.h: Declare it.
8204 * lread.c (hash_string): Remove, since we now use fns.c's version.
8205 The fns.c version returns a wider integer if --with-wide-int is
8206 specified, so this should help the quality of the hashing a bit.
8208 * emacs.c: Integer overflow minor fix.
8209 (heap_bss_diff): Now uprintmax_t, not unsigned long. All used changed.
8210 Define only if GNU_LINUX.
8211 (main, Fdump_emacs): Set and use heap_bss_diff only if GNU_LINUX.
8213 * dispnew.c: Integer signedness and overflow fixes.
8214 Remove unnecessary forward decls, that were a maintenance hassle.
8215 (history_tick): Now uprintmax_t, so it's more likely to avoid overflow.
8216 All uses changed.
8217 (adjust_glyph_matrix, realloc_glyph_pool, adjust_frame_message_buffer)
8218 (scrolling_window): Use ptrdiff_t, not int, for byte count.
8219 (prepare_desired_row, line_draw_cost):
8220 Use int, not unsigned, where either works.
8221 (save_current_matrix, restore_current_matrix):
8222 Use ptrdiff_t, not size_t, where either works.
8223 (init_display): Check for overflow more accurately, and without
8224 relying on undefined behavior.
8226 * editfns.c (pWIDE, pWIDElen, signed_wide, unsigned_wide):
8227 Remove, replacing with the new symbols in lisp.h. All uses changed.
8228 * fileio.c (make_temp_name):
8229 * filelock.c (lock_file_1, lock_file):
8230 * xdisp.c (message_dolog):
8231 Don't assume PRIdMAX etc. works; this isn't portable to pre-C99 hosts.
8232 Use pMd etc. instead.
8233 * lisp.h (printmax_t, uprintmax_t, pMd, pMu): New types and macros,
8234 replacing the pWIDE etc. symbols removed from editfns.c.
8236 * keyboard.h (num_input_events): Now uintmax_t.
8237 This is (very slightly) less likely to mess up due to wraparound.
8238 All uses changed.
8240 * buffer.c: Integer signedness fixes.
8241 (alloc_buffer_text, enlarge_buffer_text):
8242 Use ptrdiff_t rather than size_t when either will do, as we prefer
8243 signed integers.
8245 * alloc.c: Integer signedness and overflow fixes.
8246 Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
8247 (__malloc_size_t): Default to size_t, not to int.
8248 (pure_size, pure_bytes_used_before_overflow, stack_copy_size)
8249 (Fgarbage_collect, mark_object_loop_halt, mark_object):
8250 Prefer ptrdiff_t to size_t when either would do, as we prefer
8251 signed integers.
8252 (XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
8253 (xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
8254 Now const. Initialize with values that are in range even if char
8255 is signed.
8256 (XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
8257 (xmalloc_put_size, xmalloc_get_size): New functions. All uses changed.
8258 These functions do the right thing with sizes > 2**32.
8259 (check_depth): Now ptrdiff_t, not int.
8260 (overrun_check_malloc, overrun_check_realloc, overrun_check_free):
8261 Adjust to new way of storing sizes. Check for size overflow bugs
8262 in rest of code.
8263 (STRING_BYTES_MAX): Adjust to new overheads. The old code was
8264 slightly wrong anyway, as it missed one instance of
8265 XMALLOC_OVERRUN_CHECK_OVERHEAD.
8266 (refill_memory_reserve): Omit needless cast to size_t.
8267 (mark_object_loop_halt): Mark as externally visible.
8269 * xselect.c: Integer signedness and overflow fixes.
8270 (Fx_register_dnd_atom, x_handle_dnd_message):
8271 Use ptrdiff_t, not size_t, since we prefer signed.
8272 (Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
8273 * xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
8274 x_dnd_atoms_size and x_dnd_atoms_length.
8276 * doprnt.c: Prefer signed to unsigned when either works.
8277 * eval.c (verror):
8278 * doprnt.c (doprnt):
8279 * lisp.h (doprnt):
8280 * xdisp.c (vmessage):
8281 Use ptrdiff_t, not size_t, when using or implementing doprnt,
8282 since the sizes cannot exceed ptrdiff_t bounds anyway, and we
8283 prefer signed arithmetic to avoid comparison confusion.
8284 * doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
8285 but is a bit tricky.
8287 Assume freestanding C89 headers, string.h, stdlib.h.
8288 * data.c, doprnt.c, floatfns.c, print.c:
8289 Include float.h unconditionally.
8290 * gmalloc.c: Assume C89-at-least behavior for preprocessor,
8291 limits.h, stddef.h, string.h. Use memset instead of 'flood'.
8292 * regex.c: Likewise for stddef.h, string.h.
8293 (ISASCII): Remove; can assume it returns 1 now. All uses removed.
8294 * s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
8295 * s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
8296 (STDC_HEADERS): Remove obsolete defines.
8297 * sysdep.c: Include limits.h unconditionally.
8299 Assume support for memcmp, memcpy, memmove, memset.
8300 * lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
8301 * regex.c (memcmp, memcpy):
8302 Remove; we assume C89 now.
8304 * gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
8305 (__malloc_safe_bcopy): Remove; no longer needed.
8307 * lisp.h (struct vectorlike_header, struct Lisp_Subr): Signed sizes.
8308 Use EMACS_INT, not EMACS_UINT, for sizes. The code works equally
8309 well either way, and we prefer signed to unsigned.
8311 2011-07-27 Lars Magne Ingebrigtsen <larsi@gnus.org>
8313 * gnutls.c (emacs_gnutls_read): Don't message anything if the peer
8314 closes the connection while we're reading (bug#9182).
8316 2011-07-25 Jan Djärv <jan.h.d@swipnet.se>
8318 * nsmenu.m (ns_popup_dialog): Add an "ok" button if no buttons
8319 are specified (Bug#9168).
8321 2011-07-25 Paul Eggert <eggert@cs.ucla.edu>
8323 * bidi.c (bidi_dump_cached_states): Fix printf format mismatch.
8324 Found by GCC static checking and --with-wide-int on a 32-bit host.
8326 2011-07-25 Eli Zaretskii <eliz@gnu.org>
8328 * xdisp.c (compute_display_string_pos): Fix logic of caching
8329 previous display string position. Initialize cached_prev_pos to
8330 -1. Fixes slow-down at the beginning of a buffer.
8332 2011-07-24 Eli Zaretskii <eliz@gnu.org>
8334 * xfaces.c (check_lface_attrs) [HAVE_WINDOW_SYSTEM]: Allow `nil'
8335 for attrs[LFACE_FONTSET_INDEX].
8337 2011-07-23 Paul Eggert <eggert@cs.ucla.edu>
8339 * xml.c (parse_region): Remove unused local
8340 that was recently introduced.
8342 2011-07-23 Eli Zaretskii <eliz@gnu.org>
8344 * xfns.c (unwind_create_frame) [GLYPH_DEBUG]: Adapt to changes in
8345 revision 84777 on 2008-02-22.
8347 * xdisp.c (move_it_in_display_line_to): Record the best matching
8348 position for TO_CHARPOS while scanning the line, and restore it on
8349 exit if none of the characters scanned was an exact match.
8350 Fixes vertical-motion and pos-visible-in-window-p under bidi redisplay
8351 when exact match is impossible due to invisible text, and the
8352 lines are truncated.
8354 2011-07-23 Jan Djärv <jan.h.d@swipnet.se>
8356 * nsterm.m (initFrameFromEmacs): Set NSTitledWindowMask in styleMask
8357 for OSX >= 10.7.
8359 2011-07-22 Eli Zaretskii <eliz@gnu.org>
8361 Fix a significant slow-down of cursor motion with C-n, C-p,
8362 C-f/C-b, and C-v/M-v that couldn't keep up with keyboard
8363 auto-repeat under bidi redisplay in fontified buffers.
8364 * xdisp.c (compute_stop_pos_backwards): New function.
8365 (next_element_from_buffer): Call compute_stop_pos_backwards to
8366 find a suitable prev_stop when we find ourselves before
8367 base_level_stop.
8368 (reseat): Don't look for prev_stop, as that could mean a very long
8369 run.
8370 <cached_disp_pos, cached_disp_buffer, cached_disp_modiff>
8371 <cached_disp_overlay_modiff>: Cache for last found display string
8372 position.
8373 (compute_display_string_pos): Return the cached position if asked
8374 about the same buffer in the same area of character positions, and
8375 the buffer wasn't changed since the time the display string
8376 position was cached.
8378 2011-07-22 Eli Zaretskii <eliz@gnu.org>
8380 * xdisp.c (rows_from_pos_range): Don't ignore glyphs whose object
8381 is an integer, which is important for empty lines. (Bug#9149)
8383 2011-07-22 Chong Yidong <cyd@stupidchicken.com>
8385 * frame.c (Fmodify_frame_parameters): In tty case, update the
8386 default face if necessary (Bug#4238).
8388 2011-07-21 Chong Yidong <cyd@stupidchicken.com>
8390 * editfns.c (Fstring_to_char): No need to explain what a character
8391 is in the docstring (Bug#6576).
8393 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
8395 * xml.c (parse_region): Make sure we always return a tree.
8397 2011-07-20 HAMANO Kiyoto <khiker.mail@gmail.com>
8399 * xml.c (parse_region): If a document contains only comments,
8400 return that, too.
8402 2011-07-20 Lars Magne Ingebrigtsen <larsi@gnus.org>
8404 * xml.c (make_dom): Return comments, too.
8406 2011-07-19 Paul Eggert <eggert@cs.ucla.edu>
8408 Port to OpenBSD.
8409 See http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00688.html
8410 and the surrounding thread.
8411 * minibuf.c (read_minibuf_noninteractive): Rewrite to use getchar
8412 rather than fgets, and retry after EINTR. Otherwise, 'emacs
8413 --batch -f byte-compile-file' fails on OpenBSD if an inactivity
8414 timer goes off.
8415 * s/openbsd.h (BROKEN_SIGIO): Define.
8416 * unexelf.c (unexec) [__OpenBSD__]:
8417 Don't update the .mdebug section of the Alpha COFF symbol table.
8419 2011-07-19 Lars Magne Ingebrigtsen <larsi@gnus.org>
8421 * lread.c (syms_of_lread): Clarify when `lexical-binding' is used
8422 (bug#8460).
8424 2011-07-18 Paul Eggert <eggert@cs.ucla.edu>
8426 * fileio.c (Fcopy_file) [!MSDOS]: Tighten created file's mask.
8427 This fixes some race conditions on the permissions of any newly
8428 created file.
8430 * alloc.c (valid_pointer_p): Use pipe, not open.
8431 This fixes some permissions issues when debugging.
8433 * fileio.c (Fcopy_file): Adjust mode if fchown fails. (Bug#9002)
8434 If fchown fails to set both uid and gid, try to set just gid,
8435 as that is sometimes allowed. Adjust the file's mode to eliminate
8436 setuid or setgid bits that are inappropriate if fchown fails.
8438 2011-07-18 Stefan Monnier <monnier@iro.umontreal.ca>
8440 * xdisp.c (next_element_from_string, next_element_from_buffer): Use EQ
8441 to compare Lisp_Objects.
8442 * gnutls.c (syms_of_gnutls): Rename Vgnutls_log_level to
8443 global_gnutls_log_level, don't mistake it for a Lisp_Object.
8444 (init_gnutls_functions, emacs_gnutls_handle_error): Fix up uses.
8446 2011-07-17 Andreas Schwab <schwab@linux-m68k.org>
8448 * lread.c (read_integer): Unread even EOF character.
8449 (read1): Likewise. Properly record start position of symbol.
8451 * lread.c (read1): Read `#:' as empty uninterned symbol if no
8452 symbol character follows.
8454 2011-07-17 Paul Eggert <eggert@cs.ucla.edu>
8456 * fileio.c (Fcopy_file): Pacify gcc re fchown. (Bug#9002)
8457 This works around a problem with the previous change to Fcopy_file.
8458 Recent glibc declares fchown with __attribute__((warn_unused_result)),
8459 and without this change, GCC might complain about discarding
8460 fchown's return value.
8462 2011-07-16 Juanma Barranquero <lekktu@gmail.com>
8464 * makefile.w32-in (GLOBAL_SOURCES): Add gnutls.c (followup to bug#9059).
8466 2011-07-16 Paul Eggert <eggert@cs.ucla.edu>
8468 * fileio.c (Fcopy_file): Don't diagnose fchown failures. (Bug#9002)
8470 2011-07-16 Lars Magne Ingebrigtsen <larsi@gnus.org>
8472 * gnutls.c (syms_of_gnutls): Define `gnutls-log-level' here, since
8473 it's used from the C level.
8475 * process.c: Use the same condition for POLL_FOR_INPUT in both
8476 keyboard.c and process.c (bug#1858).
8478 2011-07-09 Lawrence Mitchell <wence@gmx.li>
8480 * gnutls.c (Qgnutls_bootprop_min_prime_bits): New variable.
8481 (Fgnutls_boot): Use it.
8483 2011-07-15 Andreas Schwab <schwab@linux-m68k.org>
8485 * doc.c (Fsubstitute_command_keys): Revert last change.
8487 2011-07-15 Lars Magne Ingebrigtsen <larsi@gnus.org>
8489 * doc.c (Fsubstitute_command_keys): Clarify that \= really only
8490 quotes the next character, and doesn't affect other longer
8491 sequences (bug#8935).
8493 * lread.c (syms_of_lread): Clarify that is isn't only
8494 `eval-buffer' and `eval-defun' that's affected by
8495 `lexical-binding' (bug#8460).

8500 bidi redisplay when a line includes both an image and is truncated.
8502 2011-07-14 Paul Eggert <eggert@cs.ucla.edu>
8504 Fix minor problems found by static checking.
8505 * bidi.c (bidi_cache_size): Now EMACS_INT, not size_t.
8506 (elsz): Now a signed constant, not a size_t var. We prefer signed
8507 types to unsigned, to avoid integer comparison confusion. Without
8508 this change, GCC 4.6.1 with -Wunsafe-loop-optimizations complains
8509 "cannot optimize loop, the loop counter may overflow", a symptom
8510 of the confusion.

8540 (display_string): If we need to ignore text properties of
8541 LISP_STRING, set IT->stop_charpos to IT->end_charpos. (The
8542 original value of -1 will not work with bidi.)
8543 (compute_display_string_pos): First arg is now struct
8544 `text_pos *'; all callers changed. Support display properties on
8545 Lisp strings.

8547 strings.
8548 (init_iterator, reseat_1, reseat_to_string): Initialize the
8549 string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS
8550 when iterating on a string not from display properties).

8552 Fix calculation of the object to scan. Fixes an error when using
8553 arrow keys.
8554 (next_element_from_buffer): Don't abort when IT_CHARPOS is before
8555 base_level_stop; instead, set base_level_stop to BEGV.
8556 Fixes crashes in vertical-motion.
8557 (next_element_from_buffer): Improve commentary for when
8558 the iterator is before prev_stop.
8559 (init_iterator): Initialize bidi_p from the default value of
8560 bidi-display-reordering, not from buffer-local value. Use the
8561 buffer-local value only if initializing for buffer iteration.

8580 character that is not the first one in the visual order.
8581 (get_visually_first_element): New function, refactored from common
8582 parts of next_element_from_buffer, next_element_from_string, and
8583 next_element_from_c_string.
8584 (tool_bar_lines_needed, redisplay_tool_bar)
8585 (display_menu_bar): Force left-to-right direction. Add a FIXME
8586 comment for making that be controlled by a user option.
8587 (push_it, pop_it): Save and restore the state of the
8588 bidi iterator. Save and restore the bidi_p flag.

8598 bidi-iterating.
8599 (back_to_previous_visible_line_start): If handle_display_prop
8600 pushed the iterator stack, restore the internal state of the bidi
8601 iterator by calling bidi_pop_it same number of times.
8602 (reseat_at_next_visible_line_start): If ON_NEWLINE_P is non-zero,
8603 and we are bidi-iterating, don't decrement the iterator position;
8604 instead, set the first_elt flag in the bidi iterator, to produce
8605 the same effect.
8606 (reseat_1): Remove redundant setting of string_from_display_prop_p.
8607 (push_display_prop): xassert that we are iterating a buffer.
8608 (push_it, pop_it): Save and restore paragraph_embedding member.
8609 (handle_single_display_spec, next_overlay_string)
8610 (get_overlay_strings_1, reseat_1, reseat_to_string)
8611 (push_display_prop): Set up the `unibyte' member of bidi_it.string

8620 popping after iteration over a string that came from a display
8621 property. Fix a typo in popping stretch info. Add an assertion
8622 for verifying that the iterator position is in sync with the bidi
8623 iterator.

8625 (push_display_prop): Fix initialization of paragraph direction for
8626 string when that of the parent object is not yet determined.

8628 iterator with IT's position. (Bug#7616)
8629 (find_row_edges): If ROW->start.pos gives position
8630 smaller than min_pos, use it as ROW->minpos. (Bug#7616)
8631 (handle_stop, back_to_previous_visible_line_start, reseat_1):
8632 Reset the from_disp_prop_p flag.
8633 (SAVE_IT, RESTORE_IT): New macros.

8642 (move_it_in_display_line_to): If iterator ended up at
8643 EOL, but we never saw any buffer positions smaller than
8644 to_charpos, return MOVE_POS_MATCH_OR_ZV. Fixes vertical cursor
8645 motion in bidi-reordered lines.
8646 (move_it_in_display_line_to): Record prev_method and prev_pos
8647 immediately before the call to set_iterator_to_next. Fixes cursor
8648 motion in bidi-reordered lines with stretch glyphs and strings
8649 displayed in margins. (Bug#8133) (Bug#8867)
8650 Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
8651 TO_CHARPOS.
8652 (pos_visible_p): Support positions in bidi-reordered lines.
8653 Save and restore bidi cache.
8655 * bidi.c (bidi_level_of_next_char): clen should be EMACS_NT, not int.

8691 (bidi_initialize): Initialize the bidi cache start stack pointer.
8692 (bidi_cache_ensure_space): New function, refactored from part of

9036 (clone_per_buffer_values): Don't assume that

9077 Random fixes. E.g., (random) never returned negative values.
9078 * fns.c (Frandom): Use GET_EMACS_TIME for random seed, and add the
9079 subseconds part to the entropy, as that's a bit more random.
9080 Prefer signed to unsigned, since the signedness doesn't matter and
9081 in general we prefer signed. When given a limit, use a
9082 denominator equal to INTMASK + 1, not to VALMASK + 1, because the
9083 latter isn't right if USE_2_TAGS_FOR_INTS.
9084 * sysdep.c (get_random): Return a value in the range 0..INTMASK,
9085 not 0..VALMASK. Don't discard "excess" bits that random () returns.
9087 2011-07-04 Stefan Monnier <monnier@iro.umontreal.ca>
9089 * textprop.c (text_property_stickiness):

9098 This is more efficient than Ffile_directory_p and avoids a minor race.
9100 2011-07-04 Lars Magne Ingebrigtsen <larsi@gnus.org>
9102 * buffer.c (Foverlay_put): Say what the return value is
9103 (bug#7835).

9106 is a directory before asking whether to use the file name
9107 (bug#7564).
9108 (barf_or_query_if_file_exists): Make the "File is a directory"
9109 error be more correct.
9111 * fns.c (Frequire): Remove the mention of the .gz files, since
9112 that's installation-specific, but keep the mention of
9113 `get-load-suffixes'.
9115 2011-07-04 Paul Eggert <eggert@cs.ucla.edu>
9117 * editfns.c (Fformat_time_string): Don't assume strlen fits in int.

9127 * eval.c (find_handler_clause): Remove parameters `sig' and `data',
9128 unused since revno:102982 (2011-01-26). All callers changed.
9129 Also (re)move comments that are misplaced or no longer relevant.
9131 2011-07-03 Lars Magne Ingebrigtsen <larsi@gnus.org>
9133 * callint.c (Finteractive): Clarify the meaning of "@" (bug#8813).

9192 (syms_of_keymap): Defsubr make-composed-keymap.
9193 * keyboard.c (menu_bar_items): Use map_keymap_canonical.

9228 2011-07-01 Paul Eggert <eggert@cs.ucla.edu>
9230 * eval.c (struct backtrace): Simplify and port the data structure.
9231 Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
9232 signed bit field, as this assumption is not portable and it makes
9233 Emacs crash when compiled with Sun C 5.8 on sparc. Do not use
9234 "char debug_on_exit : 1" as this is not portable either; instead,
9235 use the portable "unsigned int debug_on_exit : 1". Remove unused
9236 member evalargs. Remove obsolete comments about cc bombing out.
9238 2011-06-30 Jan Djärv <jan.h.d@swipnet.se>

9380 * process.c (syms_of_process):
9381 * search.c (syms_of_search):
9382 * sound.c (syms_of_sound):
9383 * syntax.c (init_syntax_once, syms_of_syntax):
9384 * terminal.c (syms_of_terminal):
9385 * textprop.c (syms_of_textprop):
9386 * undo.c (syms_of_undo):

9392 * xmenu.c (syms_of_xmenu):
9393 * xsettings.c (syms_of_xsettings):
9394 * xterm.c (syms_of_xterm): Use DEFSYM.
9396 2011-06-24 Teodor Zlatanov <tzz@lifelogs.com>
9398 * gnutls.c (syms_of_gnutls): Use the DEFSYM macro from character.h.
9400 2011-06-23 Paul Eggert <eggert@cs.ucla.edu>
9402 Integer and buffer overflow fixes (Bug#8873).
9404 * print.c (printchar, strout): Check for string overflow.
9405 (PRINTPREPARE, printchar, strout):
9406 Don't set size unless allocation succeeds.
9408 * minibuf.c (read_minibuf_noninteractive): Use ptrdiff_t, not int,
9409 for sizes. Check for string overflow more accurately.
9410 Simplify newline removal at end; this suppresses a GCC 4.6.0 warning.
9412 * macros.c: Integer and buffer overflow fixes.
9413 * keyboard.h (struct keyboard.kbd_macro_bufsize):
9414 * macros.c (Fstart_kbd_macro, store_kbd_macro_char):
9415 Use ptrdiff_t, not int, for sizes.
9416 Don't increment bufsize until after realloc succeeds.
9417 Check for size-calculation overflow.
9418 (Fstart_kbd_macro): Use EMACS_INT, not int, for XINT result.
9420 * lisp.h (DEFVAR_KBOARD): Use offsetof instead of char * finagling.
9422 * lread.c: Integer overflow fixes.
9423 (read_integer): Radix is now EMACS_INT, not int,
9424 to improve quality of diagnostics for out-of-range radices.
9425 Calculate buffer size correctly for out-of-range radices.
9426 (read1): Check for integer overflow in radices, and in
9427 read-circle numbers.
9428 (read_escape): Avoid int overflow.
9429 (Fload, openp, read_buffer_size, read1)
9430 (substitute_object_recurse, read_vector, read_list, map_obarray):
9431 Use ptrdiff_t, not int, for sizes.
9432 (read1): Use EMACS_INT, not int, for sizes.
9433 Check for size overflow.
9435 * image.c (cache_image): Check for size arithmetic overflow.
9437 * lread.c: Integer overflow issues.
9438 (saved_doc_string_size, saved_doc_string_length)
9439 (prev_saved_doc_string_size, prev_saved_doc_string_length):
9440 Now ptrdiff_t, not int.
9441 (read1): Don't assume doc string length fits in int. Check for
9442 out-of-range doc string lengths.
9443 (read_list): Don't assume file position fits in int.
9444 (read_escape): Check for hex character overflow.
9446 2011-06-22 Leo Liu <sdl.web@gmail.com>
9448 * minibuf.c (Fcompleting_read_default, Vcompleting_read_function):
9449 Move to minibuffer.el.
9451 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
9453 Fixes for GLYPH_DEBUG found by GCC 4.6.0 static checking.
9454 The following patches are for when GLYPH_DEBUG && !XASSERT.
9455 * dispextern.h (trace_redisplay_p, dump_glyph_string):
9456 * dispnew.c (flush_stdout):
9457 * xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
9458 Mark as externally visible.
9459 * dispnew.c (check_window_matrix_pointers): Now static.
9460 * dispnew.c (window_to_frame_vpos):
9461 * xfns.c (unwind_create_frame):
9462 * xterm.c (x_check_font): Remove unused local.
9463 * scroll.c (CHECK_BOUNDS):
9464 * xfaces.c (cache_fache): Rename local to avoid shadowing.
9465 * xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
9466 * xdisp.c (check_window_end): Now a no-op if !XASSERTS.
9467 (debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
9468 (debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
9469 Now static.
9470 (debug_method_add): Use va_list and vsprintf rather than relying
9471 on undefined behavior with wrong number of arguments.
9472 (dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
9473 Don't assume ptrdiff_t and EMACS_INT are the same width as int.
9474 In this code, it's OK to assume C99 behavior for ptrdiff_t formats
9475 since we're not interested in debugging glyphs with old libraries.
9476 * xfaces.c (cache_face): Move debugging code earlier; this pacifies
9477 GCC 4.6.0's static checking.
9479 2011-06-22 Paul Eggert <eggert@cs.ucla.edu>
9481 Integer overflow and signedness fixes (Bug#8873).

9488 (x_bitmap_mask, x_allocate_bitmap_record)
9489 (x_create_bitmap_from_data, x_create_bitmap_from_file)
9490 (x_destroy_bitmap, x_destroy_all_bitmaps, x_create_bitmap_mask)
9491 (x_create_bitmap_from_xpm_data):
9492 * nsterm.h (struct ns_display_info.bitmaps_size, .bitmaps_last):
9493 * w32term.h (struct w32_display_info.icon_bitmap_id, .bitmaps_size)
9494 (.bitmaps_last):
9495 * xfaces.c (load_pixmap):
9496 * xterm.c (x_bitmap_icon, x_wm_set_icon_pixmap):
9497 * xterm.h (struct x_display_info.icon_bitmap_id, .bitmaps_size)
9498 (.bitmaps_last, struct x_output.icon_bitmap):
9499 Use ptrdiff_t, not int, for bitmap indexes.
9500 (x_allocate_bitmap_record): Check for size overflow.
9501 * dispextern.h, lisp.h: Adjust to API changes elsewhere.
9503 Use ptrdiff_t, not int, for overlay counts.
9504 * buffer.h (overlays_at, sort_overlays, GET_OVERLAYS_AT):
9505 * editfns.c (overlays_around, get_pos_property):
9506 * textprop.c (get_char_property_and_overlay):
9507 * xdisp.c (next_overlay_change, note_mouse_highlight):
9508 * xfaces.c (face_at_buffer_position):
9509 * buffer.c (OVERLAY_COUNT_MAX): New macro.
9510 (overlays_at, overlays_in, sort_overlays, Foverlays_at)
9511 (Fnext_overlay_change, Fprevious_overlay_change)
9512 (mouse_face_overlay_overlaps, Foverlays_in):
9513 Use ptrdiff_t, not int, for sizes.
9514 (overlays_at, overlays_in): Check for size-calculation overflow.
9516 * xterm.c (xim_initialize, same_x_server): Strlen may not fit in int.
9518 * xsmfns.c (smc_save_yourself_CB, x_session_initialize): Avoid strlen.
9519 (x_session_initialize): Do not assume string length fits in int.
9521 * xsettings.c (apply_xft_settings): Fix potential buffer overrun.
9522 This is unlikely, but can occur if DPI is outlandish.
9524 * xsettings.c (Ffont_get_system_normal_font, Ffont_get_system_font):
9525 * xselect.c (Fx_get_atom_name): Avoid need for strlen.
9527 * xrdb.c: Don't assume strlen fits in int; avoid some strlens.
9528 * xrdb.c (magic_file_p, search_magic_path):
9529 Omit last arg SUFFIX; it was always 0. All callers changed.
9530 (magic_file_p): Use ptrdiff_t, not int. Check for size overflow.
9532 * xfont.c (xfont_match): Avoid need for strlen.
9534 * xfns.c: Don't assume strlen fits in int.
9535 (xic_create_fontsetname, x_window): Use ptrdiff_t, not int.
9537 * xdisp.c (message_log_check_duplicate): Return intmax_t,
9538 not unsigned long, as we prefer signed integers. All callers changed.
9539 Detect integer overflow in repeat count.
9540 (message_dolog): Don't assume print length fits in 39 bytes.
9541 (display_mode_element): Don't assume strlen fits in int.
9543 * termcap.c: Don't assume sizes fit in int and never overflow.
9544 (struct termcap_buffer, tgetent): Use ptrdiff_t, not int, for sizes.
9545 (gobble_line): Check for size-calculation overflow.
9547 * minibuf.c (Fread_buffer):
9548 * lread.c (intern, intern_c_string):
9549 * image.c (xpm_scan) [HAVE_NS && !HAVE_XPM]:
9550 Don't assume string length fits in int.
9552 * keyboard.c (parse_tool_bar_item):
9553 * gtkutil.c (style_changed_cb): Avoid need for strlen.
9555 * font.c: Don't assume string length fits in int.
9556 (font_parse_xlfd, font_parse_fcname, font_unparse_fcname):
9557 Use ptrdiff_t, not int.
9558 (font_intern_prop): Don't assume string length fits in int.
9559 Don't assume integer property fits in fixnum.
9560 * font.h (font_intern_prop): 2nd arg is now ptrdiff_t, not int.
9562 * filelock.c: Fix some buffer overrun and integer overflow issues.
9563 (get_boot_time): Don't assume gzip command string fits in 100 bytes.
9564 Reformulate so as not to need the command string.
9565 Invoke gzip -cd rather than gunzip, as it's more portable.
9566 (lock_info_type, lock_file_1, lock_file):
9567 Don't assume pid_t and time_t fit in unsigned long.
9568 (LOCK_PID_MAX): Remove; we now use more-reliable bounds.
9569 (current_lock_owner): Prefer signed type for sizes.
9570 Use memcpy, not strncpy, where memcpy is what is really wanted.
9571 Don't assume (via atoi) that time_t and pid_t fit in int.
9572 Check for time_t and/or pid_t out of range, e.g., via a network share.
9573 Don't alloca where an auto var works fine.
9575 * fileio.c: Fix some integer overflow issues.
9576 (file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
9577 Don't assume string length fits in int.
9578 (directory_file_name): Don't assume string length fits in long.
9579 (make_temp_name): Don't assume pid fits in int, or that its print
9580 length is less than 20.
9582 * data.c (Fsubr_name): Rewrite to avoid a strlen call.
9584 * coding.c (make_subsidiaries): Don't assume string length fits in int.
9586 * callproc.c (child_setup): Rewrite to avoid two strlen calls.
9588 * process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
9589 We prefer signed integers, even for size calculations.
9591 * emacs.c: Don't assume string length fits in 'int'.
9592 (DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
9593 (main): Don't invoke strlen when not needed.
9595 * dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
9596 (XD_DEBUG_MESSAGE): Don't waste a byte.
9598 * callproc.c (getenv_internal_1, getenv_internal)
9599 (Fgetenv_internal):
9600 * buffer.c (init_buffer): Don't assume string length fits in 'int'.
9602 * lread.c (invalid_syntax): Omit length argument.
9603 All uses changed. This doesn't fix a bug, but it simplifies the
9604 code away from its former Hollerith-constant appearance, and it's
9605 one less 'int' to worry about when looking at integer-overflow issues.
9606 (string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
9608 * lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
9609 This didn't break anything, but it didn't help either.
9610 It's confusing to put a bogus integer in a place where the actual
9611 value does not matter.
9612 (LIST_END_P): Remove unused macro and its bogus comment.
9613 (make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
9615 * lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
9616 This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
9617 implementation.
9618 (struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
9619 We prefer signed types, and the value cannot exceed the EMACS_INT
9620 range anyway (because otherwise the length would not be representable).
9621 (XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
9622 not EMACS_UINT and EMACS_INT, when converting pointer to integer.
9623 This avoids a GCC warning when WIDE_EMACS_INT.
9625 * indent.c (sane_tab_width): New function.
9626 (current_column, scan_for_column, Findent_to, position_indentation)
9627 (compute_motion): Use it. This is just for clarity.
9628 (Fcompute_motion): Don't assume hscroll and tab offset fit in int.
9630 * image.c (xbm_image_p): Don't assume stated width, height fit in int.
9632 * lisp.h (lint_assume): New macro.
9633 * composite.c (composition_gstring_put_cache):
9634 * ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.
9636 * editfns.c, insdel.c:
9637 Omit unnecessary forward decls, to simplify future changes.
9639 * ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.
9641 * font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.
9643 * fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
9644 Use much-faster test for byte-length change.
9645 Don't assume string byte-length fits in 'int'.
9646 Check that character arg fits in 'int'.
9647 (mapcar1): Declare byte as byte, for clarity.
9649 * alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.
9651 * fns.c (concat): Catch string overflow earlier.
9652 Do not rely on integer wraparound.
9654 * dispextern.h (struct it.overlay_strings_charpos)
9655 (struct it.selective): Now EMACS_INT, not int.
9656 * xdisp.c (forward_to_next_line_start)
9657 (back_to_previous_visible_line_start)
9658 (reseat_at_next_visible_line_start, next_element_from_buffer):
9659 Don't arbitrarily truncate the value of 'selective' to int.
9661 * xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.
9663 * composite.c: Don't truncate sizes to 'int'.
9664 (composition_gstring_p, composition_reseat_it)
9665 (composition_adjust_point): Use EMACS_INT, not int.
9666 (get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
9667 not EMACS_UINT, for indexes.
9669 * category.h (CATEGORY_SET_P): Remove unnecessary cast to EMACS_INT.
9671 * buffer.c: Include <verify.h>.
9672 (struct sortvec.priority, struct sortstr.priority):
9673 Now EMACS_INT, not int.
9674 (compare_overlays, cmp_for_strings): Avoid subtraction overflow.
9675 (struct sortstr.size, record_overlay_string)
9676 (struct sortstrlist.size, struct sortlist.used):
9677 Don't truncate size to int.
9678 (record_overlay_string): Check for size-calculation overflow.
9679 (init_buffer_once): Check at compile-time, not run-time.
9681 2011-06-22 Jim Meyering <meyering@redhat.com>
9683 Don't leak an XBM-image-sized buffer
9684 * image.c (xbm_load): Free the image buffer after using it.
9686 2011-06-21 Paul Eggert <eggert@cs.ucla.edu>
9688 Port to Sun C.
9689 * composite.c (find_automatic_composition): Omit needless 'return 0;'
9690 that Sun C diagnosed.
9691 * fns.c (secure_hash): Fix pointer signedness issue.
9692 * intervals.c (static_offset_intervals): New function.
9693 (offset_intervals): Use it.
9695 2011-06-21 Leo Liu <sdl.web@gmail.com>
9697 * deps.mk (fns.o):
9698 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha256.h and
9699 sha512.h.
9701 * fns.c (secure_hash): Rename from crypto_hash_function and change
9702 the first arg to accept symbols.
9703 (Fsecure_hash): New primitive.
9704 (syms_of_fns): New symbols.
9706 2011-06-20 Deniz Dogan <deniz@dogan.se>
9708 * process.c (Fset_process_buffer): Clarify return value in
9709 docstring.
9711 2011-06-18 Chong Yidong <cyd@stupidchicken.com>
9713 * dispnew.c (add_window_display_history): Use BVAR.
9715 * xdisp.c (debug_method_add): Use BVAR.
9716 (check_window_end, dump_glyph_matrix, dump_glyph)
9717 (dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.
9719 * xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
9720 Likewise.
9722 * xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
9723 check till after the cache is created in init_frame_faces.
9725 2011-06-17 Stefan Monnier <monnier@iro.umontreal.ca>
9727 * fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.
9729 2011-06-16 Paul Eggert <eggert@cs.ucla.edu>
9731 * lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
9732 Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
9733 hosts with pre-C99 libraries, because pD is wrongly defined to "t".
9735 Improve buffer-overflow checking (Bug#8873).
9736 * fileio.c (Finsert_file_contents):
9737 * insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
9738 Remove the old (too-loose) buffer overflow checks.
9739 They weren't needed, since make_gap checks for buffer overflow.
9740 * insdel.c (make_gap_larger): Catch buffer overflows that were missed.
9741 The old code merely checked for Emacs fixnum overflow, and relied
9742 on undefined (wraparound) behavior. The new code avoids undefined
9743 behavior, and also checks for ptrdiff_t and/or size_t overflow.
9745 * editfns.c (Finsert_char): Don't dump core with very negative counts.
9746 Tune. Don't use wider integers than needed. Don't use alloca.
9747 Use a bigger 'string' buffer. Rewrite to avoid 'n > 0' test.
9749 * insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.
9751 * insdel.c, lisp.h (buffer_overflow): New function.
9752 (insert_from_buffer_1, replace_range, replace_range_2):
9753 * insdel.c (make_gap_larger):
9754 * editfns.c (Finsert_char):
9755 * fileio.c (Finsert_file_contents): Use it, to normalize wording.
9757 * buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.
9759 2011-06-15 Paul Eggert <eggert@cs.ucla.edu>
9761 Integer overflow and signedness fixes (Bug#8873, Bug#8828).
9763 * ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
9764 (GET_CCL_RANGE, IN_INT_RANGE): Use it.
9766 * fileio.c: Don't assume EMACS_INT fits in off_t.
9767 (emacs_lseek): New static function.
9768 (Finsert_file_contents, Fwrite_region): Use it.
9769 Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.
9771 * fns.c (Fload_average): Don't assume 100 * load average fits in int.
9773 * fns.c: Don't overflow int when computing a list length.
9774 * fns.c (QUIT_COUNT_HEURISTIC): New constant.
9775 (Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
9776 truncation on 64-bit hosts. Check for QUIT every
9777 QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
9778 faster and is responsive enough.
9779 (Flength): Report an error instead of overflowing an integer.
9780 (Fsafe_length): Return a float if the value is not representable
9781 as a fixnum. This shouldn't happen except in contrived situations.
9782 (Fnthcdr, Fsort): Don't assume list length fits in int.
9783 (Fcopy_sequence): Don't assume vector length fits in int.
9785 * alloc.c: Check that resized vectors' lengths fit in fixnums.
9786 (header_size, word_size): New constants.
9787 (allocate_vectorlike): Don't check size overflow here.
9788 (allocate_vector): Check it here instead, since this is the only
9789 caller of allocate_vectorlike that could cause overflow.
9790 Check that the new vector's length is representable as a fixnum.
9792 * fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
9793 The previous code was bogus. For example, next_almost_prime (32)
9794 returned 39, which is undesirable as it is a multiple of 3; and
9795 next_almost_prime (24) returned 25, which is a multiple of 5 so
9796 why was the code bothering to check for multiples of 7?
9798 * bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.
9800 * eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.
9802 Variadic C functions now count arguments with ptrdiff_t.
9803 This partly undoes my 2011-03-30 change, which replaced int with size_t.
9804 Back then I didn't know that the Emacs coding style prefers signed int.
9805 Also, in the meantime I found a few more instances where arguments
9806 were being counted with int, which may truncate counts on 64-bit
9807 machines, or EMACS_INT, which may be unnecessarily wide.
9808 * lisp.h (struct Lisp_Subr.function.aMANY)
9809 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
9810 Arg counts are now ptrdiff_t, not size_t.
9811 All variadic functions and their callers changed accordingly.
9812 (struct gcpro.nvars): Now size_t, not size_t. All uses changed.
9813 * bytecode.c (exec_byte_code): Check maxdepth for overflow,
9814 to avoid potential buffer overrun. Don't assume arg counts fit in 'int'.
9815 * callint.c (Fcall_interactively): Check arg count for overflow,
9816 to avoid potential buffer overrun. Use signed char, not 'int',
9817 for 'varies' array, so that we needn't bother to check its size
9818 calculation for overflow.
9819 * editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
9820 * eval.c (apply_lambda):
9821 * fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
9822 (struct textprop_rec.argnum): Now ptrdiff_t, not int. All uses changed.
9823 (mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.
9825 * callint.c (Fcall_interactively): Don't use index var as event count.
9827 * vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
9828 * mem-limits.h (SIZE): Remove; no longer used.
9830 * xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.
9832 Remove unnecessary casts.
9833 * xterm.c (x_term_init):
9834 * xfns.c (x_set_border_pixel):
9835 * widget.c (create_frame_gcs): Remove casts to unsigned long etc.
9836 These aren't needed now that we assume ANSI C.
9838 * sound.c (Fplay_sound_internal): Remove cast to unsigned long.
9839 It's more likely to cause problems (due to unsigned overflow)
9840 than to cure them.
9842 * dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.
9844 * unexelf.c (unexec): Don't assume BSS addr fits in unsigned.
9846 * xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.
9848 * keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.
9850 * lisp.h (CHAR_TABLE_SET): Omit now-redundant test.
9852 * lread.c (Fload): Don't compare a possibly-garbage time_t value.
9854 GLYPH_CODE_FACE returns EMACS_INT, not int.
9855 * dispextern.h (merge_faces):
9856 * xfaces.c (merge_faces):
9857 * xdisp.c (get_next_display_element, next_element_from_display_vector):
9858 Don't assume EMACS_INT fits in int.
9860 * character.h (CHAR_VALID_P): Remove unused parameter.
9861 * fontset.c, lisp.h, xdisp.c: All uses changed.
9863 * editfns.c (Ftranslate_region_internal): Omit redundant test.
9865 * fns.c (concat): Minor tuning based on overflow analysis.
9866 This doesn't fix any bugs. Use int to hold character, instead
9867 of constantly refetching from Emacs object. Use XFASTINT, not
9868 XINT, for value known to be a character. Don't bother comparing
9869 a single byte to 0400, as it's always less.
9871 * floatfns.c (Fexpt):
9872 * fileio.c (make_temp_name): Omit unnecessary cast to unsigned.
9874 * editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
9875 for characters.
9877 * doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.
9879 * data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
9880 Without this fix, on a 64-bit host (aset S 0 4294967386) would
9881 incorrectly succeed when S was a string, because 4294967386 was
9882 truncated before it was used.
9884 * chartab.c (Fchar_table_range): Use CHARACTERP to check range.
9885 Otherwise, an out-of-range integer could cause undefined behavior
9886 on a 64-bit host.
9888 * composite.c: Use int, not EMACS_INT, for characters.
9889 (fill_gstring_body, composition_compute_stop_pos): Use int, not
9890 EMACS_INT, for values that are known to be in character range.
9891 This doesn't fix any bugs but is the usual style inside Emacs and
9892 may generate better code on 32-bit machines.
9894 Make sure a 64-bit char is never passed to ENCODE_CHAR.
9895 This is for reasons similar to the recent CHAR_STRING fix.
9896 * charset.c (Fencode_char): Check that character arg is actually
9897 a character. Pass an int to ENCODE_CHAR.
9898 * charset.h (ENCODE_CHAR): Verify that the character argument is no
9899 wider than 'int', as a compile-time check to prevent future regressions
9900 in this area.
9902 * character.c (char_string): Remove unnecessary casts.
9904 Make sure a 64-bit char is never passed to CHAR_STRING.
9905 Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
9906 by silently ignoring the top 32 bits, allowing some values
9907 that were far too large to be valid characters.
9908 * character.h: Include <verify.h>.
9909 (CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
9910 arguments are no wider than unsigned, as a compile-time check
9911 to prevent future regressions in this area.
9912 * data.c (Faset):
9913 * editfns.c (Fchar_to_string, general_insert_function, Finsert_char)
9914 (Fsubst_char_in_region):
9915 * fns.c (concat):
9916 * xdisp.c (decode_mode_spec_coding):
9917 Adjust to CHAR_STRING's new requirement.
9918 * editfns.c (Finsert_char, Fsubst_char_in_region):
9919 * fns.c (concat): Check that character args are actually
9920 characters. Without this test, these functions did the wrong
9921 thing with wildly out-of-range values on 64-bit hosts.
9923 Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
9924 These casts should not be needed on 32-bit hosts, either.
9925 * keyboard.c (read_char):
9926 * lread.c (Fload): Remove casts to unsigned.
9928 * lisp.h (UNSIGNED_CMP): New macro.
9929 This fixes comparison bugs on 64-bit hosts.
9930 (ASCII_CHAR_P): Use it.
9931 * casefiddle.c (casify_object):
9932 * character.h (ASCII_BYTE_P, CHAR_VALID_P)
9933 (SINGLE_BYTE_CHAR_P, CHAR_STRING):
9934 * composite.h (COMPOSITION_ENCODE_RULE_VALID):
9935 * dispextern.h (FACE_FROM_ID):
9936 * keyboard.c (read_char): Use UNSIGNED_CMP.
9938 * xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
9939 not to EMACS_INT, to avoid GCC warning.
9941 * xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.
9943 * buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
9944 The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
9945 isn't needed on 32-bit machines.
9947 * buffer.c (Fgenerate_new_buffer_name):
9948 Use EMACS_INT for count, not int.
9949 (advance_to_char_boundary): Return EMACS_INT, not int.
9951 * data.c (Qcompiled_function): Now static.
9953 * window.c (window_body_lines): Now static.
9955 * image.c (gif_load): Rename local to avoid shadowing.
9957 * lisp.h (SAFE_ALLOCA_LISP): Check for integer overflow.
9958 (struct Lisp_Save_Value): Use ptrdiff_t, not int, for 'integer' member.
9959 * alloc.c (make_save_value): Integer argument is now of type
9960 ptrdiff_t, not int.
9961 (mark_object): Use ptrdiff_t, not int.
9962 * lisp.h (pD): New macro.
9963 * print.c (print_object): Use it.
9965 * alloc.c: Use EMACS_INT, not int, to count objects.
9966 (total_conses, total_markers, total_symbols, total_vector_size)
9967 (total_free_conses, total_free_markers, total_free_symbols)
9968 (total_free_floats, total_floats, total_free_intervals)
9969 (total_intervals, total_strings, total_free_strings):
9970 Now EMACS_INT, not int. All uses changed.
9971 (Fgarbage_collect): Compute overall total using a double, so that
9972 integer overflow is less likely to be a problem. Check for overflow
9973 when converting back to an integer.
9974 (n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
9975 (n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
9976 These were 'int' variables that could overflow on 64-bit hosts;
9977 they were never used, so remove them instead of repairing them.
9978 (nzombies, ngcs, max_live, max_zombies): Now EMACS_INT, not 'int'.
9979 (inhibit_garbage_collection): Set gc_cons_threshold to max value.
9980 Previously, this ceilinged at INT_MAX, but that doesn't work on
9981 64-bit machines.
9982 (allocate_pseudovector): Don't use EMACS_INT when int would do.
9984 * alloc.c (Fmake_bool_vector): Don't assume vector size fits in int.
9985 (allocate_vectorlike): Check for ptrdiff_t overflow.
9986 (mark_vectorlike, mark_char_table, mark_object): Avoid EMACS_UINT
9987 when a (possibly-narrower) signed value would do just as well.
9988 We prefer using signed arithmetic, to avoid comparison confusion.
9990 * alloc.c: Catch some string size overflows that we were missing.
9991 (XMALLOC_OVERRUN_CHECK_SIZE) [!XMALLOC_OVERRUN_CHECK]: Define to 0,
9992 for convenience in STRING_BYTES_MAX.
9993 (STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
9994 The definition here is exact; the one in lisp.h was approximate.
9995 (allocate_string_data): Check for string overflow. This catches
9996 some instances we weren't catching before. Also, it catches
9997 size_t overflow on (unusual) hosts where SIZE_MAX <= min
9998 (PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
9999 and ptrdiff_t and EMACS_INT are both 64 bits.
10001 * character.c, coding.c, doprnt.c, editfns.c, eval.c:
10002 All uses of STRING_BYTES_MAX replaced by STRING_BYTES_BOUND.
10003 * lisp.h (STRING_BYTES_BOUND): Rename from STRING_BYTES_MAX.
10005 * character.c (string_escape_byte8): Fix nbytes/nchars typo.
10007 * alloc.c (Fmake_string): Check for out-of-range init.
10009 2011-06-15 Stefan Monnier <monnier@iro.umontreal.ca>
10011 * eval.c (Fdefvaralias): Also mark the target as variable-special-p.
10013 2011-06-14 Jan Djärv <jan.h.d@swipnet.se>
10015 * xfns.c (x_set_scroll_bar_default_width): Remove argument to
10016 xg_get_default_scrollbar_width.
10018 * gtkutil.c: Include emacsgtkfixed.h if HAVE_GTK3.
10019 (int_gtk_range_get_value): Move to the scroll bar part of the file.
10020 (style_changed_cb): Call update_theme_scrollbar_width and call

10028 (update_theme_scrollbar_width): New function.
10029 (xg_get_default_scrollbar_width): Move code to
10030 update_theme_scrollbar_width, just return scroll_bar_width_for_theme.
10031 (xg_initialize): Call update_theme_scrollbar_width.
10033 * gtkutil.h (xg_get_default_scrollbar_width): Remove argument.
10035 * emacsgtkfixed.c, emacsgtkfixed.h: New files.
10037 2011-06-12 Martin Rudalics <rudalics@gmx.at>
10039 * frame.c (make_frame): Call other_buffer_safely instead of
10040 other_buffer.
10042 * window.c (temp_output_buffer_show): Call display_buffer with
10043 second argument Vtemp_buffer_show_specifiers and reset latter
10044 immediately after the call.
10045 (Vtemp_buffer_show_specifiers): New variable.
10046 (auto_window_vscroll_p, next_screen_context_lines)
10047 (Vscroll_preserve_screen_position): Remove leading asterisks from
10048 doc-strings.

10093 (Fset_window_configuration): Rewrite to handle dead buffers and
10094 consequently deletable windows.
10095 (window_tree, Fwindow_tree): Remove. Supply functionality in
10096 window.el.

10115 buffer list implementation.
10116 (other_buffer_safely): New function.
10117 (Fkill_buffer): Replace call to replace_buffer_in_all_windows by
10118 calls to replace_buffer_in_windows and
10119 replace_buffer_in_windows_safely. Run Qbuffer_list_update_hook
10120 if allowed.
10121 (record_buffer): Inhibit quitting and rewrite using quittable
10122 functions. Run Qbuffer_list_update_hook if allowed.
10123 (Frecord_buffer, Funrecord_buffer): New functions.

10227 * window.c: Remove declarations of Qwindow_size_fixed,
10228 window_min_size_1, window_min_size_2, window_min_size,
10229 size_window, window_fixed_size_p, enlarge_window, delete_window.

10580 instead of using explicit *_CHAR codes.
10581 (bidi_resolve_explicit, bidi_resolve_weak):
10582 Use FETCH_MULTIBYTE_CHAR instead of FETCH_CHAR, as reordering of
10583 bidirectional text is supported only in multibyte buffers.

10594 * xdisp.c (set_cursor_from_row): Set start and stop points
10595 according to the row's direction when priming the loop that looks

10598 (display_prop_intangible_p): Reimplement to call
10599 handle_display_spec instead of single_display_spec_intangible_p.

10611 value of a `display' property is a "replacing spec".
10612 (handle_single_display_spec): Accept 2 additional arguments BUFPOS
10613 and FRAME_WINDOW_P. If IT is NULL, don't set up the iterator from

10641 All callers changed. (Bug#8762)
10643 * gnutls.c: Use Emacs's memory allocators.
10644 Without this change, the gnutls library would invoke malloc etc.
10645 directly, which causes problems on non-SYNC_INPUT hosts, and which
10646 runs afoul of improving memory_full behavior. (Bug#8761)
10647 (fn_gnutls_global_set_mem_functions): New macro or function pointer.
10648 (emacs_gnutls_global_init): Use it to specify xmalloc, xrealloc,
10649 xfree instead of the default malloc, realloc, free.
10650 (Fgnutls_boot): No need to check for memory allocation failure,
10651 since xmalloc does that for us.

10674 for hashes and hash indexes, instead of 'unsigned' and 'int'.
10675 * alloc.c (allocate_vectorlike):
10676 Check for overflow in vector size calculations.
10677 * ccl.c (ccl_driver):
10678 Check for overflow when converting EMACS_INT to int.
10679 * fns.c, image.c: Remove unnecessary static decls that would otherwise
10680 need to be updated by these changes.
10681 * fns.c (make_hash_table, maybe_resize_hash_table):
10682 Check for integer overflow with large hash tables.
10683 (make_hash_table, maybe_resize_hash_table, Fmake_hash_table):
10684 Prefer the faster XFLOAT_DATA to XFLOATINT where either will do.
10685 (SXHASH_REDUCE): New macro.
10686 (sxhash_string, sxhash_list, sxhash_vector, sxhash_bool_vector):
10687 Use it instead of discarding useful hash info with large hash values.
10688 (sxhash_float): New function.
10689 (sxhash): Use it. No more need for "& INTMASK" due to above changes.
10690 * lisp.h (FIXNUM_BITS): New macro, useful for SXHASH_REDUCE etc.
10691 (MOST_NEGATIVE_FIXNUM, MOST_POSITIVE_FIXNUM, INTMASK):
10692 Rewrite to use FIXNUM_BITS, as this simplifies things.
10693 (next_almost_prime, larger_vector, sxhash, hash_lookup, hash_put):
10694 Adjust signatures to match updated version of code.
10695 (consing_since_gc): Now EMACS_INT, since a single hash table can
10696 use more than INT_MAX bytes.
10698 2011-06-01 Dan Nicolaescu <dann@ics.uci.edu>
10700 Make it possible to build with GCC-4.6+ -O2 -flto.
10702 * emacs.c (__malloc_initialize_hook): Mark as EXTERNALLY_VISIBLE.
10704 2011-06-01 Stefan Monnier <monnier@iro.umontreal.ca>
10706 * minibuf.c (get_minibuffer, read_minibuf_unwind):
10707 Call minibuffer-inactive-mode.
10709 2011-05-31 Juanma Barranquero <lekktu@gmail.com>
10711 * makefile.w32-in ($(BLD)/data.$(O), $(BLD)/editfns.$(O)):
10712 Update dependencies.
10714 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
10716 * data.c (init_data): Remove code for UTS, this system is not
10717 supported anymore.
10719 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
10721 Don't force ./temacs to start in terminal mode.
10723 * frame.c (make_initial_frame): Initialize faces in all cases, not
10724 only when CANNOT_DUMP is defined.
10725 * dispnew.c (init_display): Remove CANNOT_DUMP condition.
10727 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
10729 * dispnew.c (add_window_display_history): Use const for the string
10730 pointer. Remove declaration, not needed.
10732 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
10734 Use 'inline', not 'INLINE'.
10735 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00914.html>
10736 * alloc.c, fontset.c (INLINE): Remove.
10737 * alloc.c, bidi.c, charset.c, coding.c, dispnew.c, fns.c, image.c:
10738 * intervals.c, keyboard.c, process.c, syntax.c, textprop.c, w32term.c:
10739 * xdisp.c, xfaces.c, xterm.c: Replace all uses of INLINE with inline.
10740 * gmalloc.c (register_heapinfo): Use inline unconditionally.
10741 * lisp.h (LISP_MAKE_RVALUE): Use inline, not __inline__.
10743 2011-05-31 Dan Nicolaescu <dann@ics.uci.edu>
10745 Make it possible to run ./temacs.
10747 * callproc.c (set_initial_environment): Remove CANNOT_DUMP code,
10748 syms_of_callproc does the same thing. Remove test for
10749 "initialized", do it in the caller.
10750 * emacs.c (main): Avoid calling set_initial_environment when dumping.
10752 2011-05-31 Stefan Monnier <monnier@iro.umontreal.ca>
10754 * minibuf.c (Finternal_complete_buffer): Return `category' metadata.
10755 (read_minibuf): Use get_minibuffer.
10756 (syms_of_minibuf): Use DEFSYM.
10757 (Qmetadata): New var.
10758 * data.c (Qbuffer): Don't make it static.
10759 (syms_of_data): Use DEFSYM.
10761 2011-05-31 Paul Eggert <eggert@cs.ucla.edu>
10763 * ccl.c (CCL_CODE_RANGE): Allow negative numbers. (Bug#8751)
10764 (CCL_CODE_MIN): New macro.
10766 2011-05-30 Paul Eggert <eggert@cs.ucla.edu>
10768 * alloc.c (lisp_align_malloc): Omit unnecessary val==NULL tests.
10770 * eval.c (Qdebug): Now static.
10771 * lisp.h (Qdebug): Remove decl. This reverts a part of the
10772 2011-04-26 change (bzr 104015) that inadvertently undid part of
10773 the 2011-04-14 change (bzr 103913).
10775 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
10777 * image.c: Various fixes to ImageMagick code comments.
10778 (Fimagemagick_types): Doc fix.
10780 2011-05-29 Paul Eggert <eggert@cs.ucla.edu>
10782 Minor fixes prompted by GCC 4.6.0 warnings.
10784 * xselect.c (converted_selections, conversion_fail_tag): Now static.
10786 * emacs.c [HAVE_X_WINDOWS]: Include "xterm.h".
10787 (x_clipboard_manager_save_all): Move extern decl to ...
10788 * xterm.h: ... here, so that it can be checked for consistency.
10790 2011-05-29 Chong Yidong <cyd@stupidchicken.com>
10792 * xselect.c (x_clipboard_manager_save_frame)
10793 (x_clipboard_manager_save_all): New functions.
10794 (Fx_clipboard_manager_save): Lisp function deleted.
10796 * emacs.c (Fkill_emacs): Call x_clipboard_manager_save_all.
10797 * frame.c (delete_frame): Call x_clipboard_manager_save_frame.
10799 * xterm.h: Update prototype.
10801 2011-05-28 William Xu <william.xwl@gmail.com>
10803 * nsterm.m (ns_term_shutdown): Synchronize user defaults before
10804 exiting (Bug#8239).
10806 2011-05-28 Jim Meyering <meyering@redhat.com>
10808 Avoid a sign-extension bug in crypto_hash_function.
10809 * fns.c (to_uchar): Define.
10810 (crypto_hash_function): Use it to convert some newly-signed
10811 variables to unsigned, to avoid sign-extension bugs. For example,
10812 without this change, (md5 "truc") would evaluate to
10813 45723a2aff78ff4fff7fff1114760e62 rather than the expected
10814 45723a2af3788c4ff17f8d1114760e62. Reported by Antoine Levitt in
10815 https://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00883.html.
10817 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
10819 Integer overflow fixes.
10821 * dbusbind.c: Serial number integer overflow fixes.
10822 (CHECK_DBUS_SERIAL_GET_SERIAL): New macro.
10823 (Fdbus_call_method_asynchronously, xd_read_message_1): Use a float
10824 to hold a serial number that is too large for a fixnum.
10825 (Fdbus_method_return_internal, Fdbus_method_error_internal):
10826 Check for serial numbers out of range. Decode any serial number
10827 that was so large that it became a float. (Bug#8722)
10829 * dbusbind.c: Use XFASTINT rather than XUINT, and check for nonneg.
10830 (Fdbus_call_method, Fdbus_call_method_asynchronously):
10831 Use XFASTINT rather than XUINT when numbers are nonnegative.
10832 (xd_append_arg, Fdbus_method_return_internal):
10833 (Fdbus_method_error_internal): Likewise. Also, for unsigned
10834 arguments, check that Lisp number is nonnegative, rather than
10835 silently wrapping negative numbers around. (Bug#8722)
10836 (xd_read_message_1): Don't assume dbus_uint32_t can fit in int.
10837 (Bug#8722)
10839 * data.c (arith_driver, Flsh): Avoid unnecessary casts to EMACS_UINT.
10841 * ccl.c (ccl_driver): Redo slightly to avoid the need for 'unsigned'.
10843 ccl: Add integer overflow checks.
10844 * ccl.c (CCL_CODE_MAX, GET_CCL_RANGE, GET_CCL_CODE, GET_CCL_INT):
10845 (IN_INT_RANGE): New macros.
10846 (ccl_driver): Use them to check for integer overflow when
10847 decoding a CCL program. Many of the new checks are whether XINT (x)
10848 fits in int; it doesn't always, on 64-bit hosts. The new version
10849 doesn't catch all possible integer overflows, but it's an
10850 improvement. (Bug#8719)
10852 * alloc.c (make_event_array): Use XINT, not XUINT.
10853 There's no need for unsigned here.
10855 * mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
10856 This follows up to the 2011-05-06 change that substituted uintptr_t
10857 for EMACS_INT. This case wasn't caught back then.
10859 Rework Fformat to avoid integer overflow issues.
10860 * editfns.c: Include <float.h> unconditionally, as it's everywhere
10861 now (part of C89). Include <verify.h>.
10862 (MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
10863 (pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
10864 (Fformat): Avoid the prepass trying to compute sizes; it was only
10865 approximate and thus did not catch overflow reliably. Instead, walk
10866 through the format just once, formatting and computing sizes as we go,
10867 checking for integer overflow at every step, and allocating a larger
10868 buffer as needed. Keep track separately whether the format is
10869 multibyte. Keep only the most-recently calculated precision, rather
10870 than them all. Record whether each argument has been converted to
10871 string. Use EMACS_INT, not int, for byte and char and arg counts.
10872 Support field widths and precisions larger than INT_MAX. Avoid
10873 sprintf's undefined behavior with conversion specifications such as %#d
10874 and %.0c. Fix bug with strchr succeeding on '\0' when looking for
10875 flags. Fix bug with (format "%c" 256.0). Avoid integer overflow when
10876 formatting out-of-range floating point numbers with int
10877 formats. (Bug#8668)
10879 * lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.
10881 * data.c: Avoid integer truncation in expressions involving floats.
10882 * data.c: Include <intprops.h>.
10883 (arith_driver): When there's an integer overflow in an expression
10884 involving floating point, convert the integers to floating point
10885 so that the resulting value does not suffer from catastrophic
10886 integer truncation. For example, on a 64-bit host (* 4
10887 most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
10888 Do not rely on undefined behavior after integer overflow.
10890 merge count_size_as_multibyte, parse_str_to_multibyte
10891 * character.c, character.h (count_size_as_multibyte):
10892 Rename from parse_str_to_multibyte; all uses changed.
10893 Check for integer overflow.
10894 * insdel.c, lisp.h (count_size_as_multibyte): Remove,
10895 since it's now a duplicate of the other. This is more of
10896 a character than a buffer op, so better that it's in character.c.
10897 * fns.c, print.c: Adjust to above changes.
10899 2011-05-27 Stefan Monnier <monnier@iro.umontreal.ca>
10901 * xselect.c (x_convert_selection): Yet another int/Lisp_Object mixup.
10903 2011-05-27 Paul Eggert <eggert@cs.ucla.edu>
10905 * xselect.c: Fix minor problems prompted by GCC 4.6.0 warnings.
10906 (x_handle_selection_request, frame_for_x_selection): Remove unused vars.
10907 (x_clipboard_manager_save): Now static.
10908 (Fx_clipboard_manager_save): Rename local to avoid shadowing.
10910 * fns.c: Fix minor problems prompted by GCC 4.6.0 warnings.
10911 (crypto_hash_function): Now static.
10912 Fix pointer signedness problems. Avoid unnecessary initializations.
10914 2011-05-27 Chong Yidong <cyd@stupidchicken.com>
10916 * termhooks.h (Vselection_alist): Make it terminal-local.
10918 * terminal.c (create_terminal): Initialize it.
10920 * xselect.c: Support for clipboard managers.
10921 (Vselection_alist): Move to termhooks.h as terminal-local var.
10922 (LOCAL_SELECTION): New macro.
10923 (x_atom_to_symbol): Handle x_display_info_for_display fail case.
10924 (symbol_to_x_atom): Remove gratuitous arg.
10925 (x_handle_selection_request, lisp_data_to_selection_data)
10926 (x_get_foreign_selection, Fx_register_dnd_atom): Callers changed.
10927 (x_own_selection, x_get_local_selection, x_convert_selection):
10928 New arg, specifying work frame. Use terminal-local Vselection_alist.
10929 (some_frame_on_display): Delete unused function.
10930 (Fx_own_selection_internal, Fx_get_selection_internal)
10931 (Fx_disown_selection_internal, Fx_selection_owner_p)
10932 (Fx_selection_exists_p): New optional frame arg.
10933 (frame_for_x_selection, Fx_clipboard_manager_save): New functions.
10934 (x_handle_selection_clear): Don't treat other terminals with the
10935 same keyboard specially. Use the terminal-local Vselection_alist.
10936 (x_clear_frame_selections): Use Frun_hook_with_args.
10938 * xterm.c (x_term_init): Intern ATOM and CLIPBOARD_MANAGER atoms.
10940 * xterm.h: Add support for those atoms.
10942 2011-05-26 Chong Yidong <cyd@stupidchicken.com>
10944 * xselect.c: ICCCM-compliant handling of MULTIPLE targets.
10945 (converted_selections, conversion_fail_tag): New global variables.
10946 (x_selection_request_lisp_error): Free the above.
10947 (x_get_local_selection): Remove unnecessary code.
10948 (x_reply_selection_request): Args changed; handle arbitrary array
10949 of converted selections stored in converted_selections.
10950 Separate the XChangeProperty and SelectionNotify steps.
10951 (x_handle_selection_request): Rewrite to handle MULTIPLE target.
10952 (x_convert_selection): New function.
10953 (x_handle_selection_event): Simplify.
10954 (x_get_foreign_selection): Don't ignore incoming requests while
10955 waiting for an answer; this will fail when we implement
10956 SAVE_TARGETS, and seems unnecessary anyway.
10957 (selection_data_to_lisp_data): Recognize ATOM_PAIR type.
10958 (Vx_sent_selection_functions): Doc fix.
10960 2011-05-26 Leo Liu <sdl.web@gmail.com>
10962 * editfns.c (Ftranspose_regions): Allow empty regions. (Bug#8699)
10964 2011-05-25 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
10966 * dispextern.h (struct glyph_row): New member fringe_bitmap_periodic_p.
10968 * dispnew.c (shift_glyph_matrix, scrolling_window): Mark scrolled row
10969 for fringe update if it has periodic bitmap.
10970 (row_equal_p): Also compare left_fringe_offset, right_fringe_offset,
10971 and fringe_bitmap_periodic_p.
10973 * fringe.c (get_fringe_bitmap_data): New function.
10974 (draw_fringe_bitmap_1, update_window_fringes): Use it.
10975 (update_window_fringes): Record periodicity of fringe bitmap in glyph
10976 row. Mark glyph row for fringe update if periodicity changed.
10978 * xdisp.c (try_window_reusing_current_matrix): Don't mark scrolled row
10979 for fringe update unless it has periodic bitmap.
10981 2011-05-25 Kenichi Handa <handa@m17n.org>
10983 * xdisp.c (get_next_display_element): Set correct it->face_id for
10984 a static composition.
10986 2011-05-24 Leo Liu <sdl.web@gmail.com>
10988 * deps.mk (fns.o):
10989 * makefile.w32-in ($(BLD)/fns.$(O)): Include sha1.h.
10991 * fns.c (crypto_hash_function, Fsha1): New function.
10992 (Fmd5): Use crypto_hash_function.
10993 (syms_of_fns): Add Ssha1.
10995 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
10997 * gnutls.c: Remove unused macros.
10998 (fn_gnutls_transport_set_lowat, fn_gnutls_transport_set_pull_function):
10999 (fn_gnutls_transport_set_push_function) [!WINDOWSNT]:
11000 Remove macros that are defined and never used.
11001 Caught by gcc -Wunused-macros (GCC 4.6.0, Fedora 14).
11003 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
11005 * xselect.c (syms_of_xselect): Remove unused symbol SAVE_TARGETS.
11006 (Fx_get_selection_internal): Minor cleanup.
11007 (Fx_own_selection_internal): Rename arguments for consistency with
11008 select.el.
11010 2011-05-22 Paul Eggert <eggert@cs.ucla.edu>
11012 * xselect.c (QSAVE_TARGETS): New static var, to fix build failure.
11014 2011-05-22 Chong Yidong <cyd@stupidchicken.com>
11016 * xselect.c (syms_of_xselect): Include character.h; use DEFSYM.
11018 2011-05-21 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11020 * dispnew.c (scrolling_window): Don't exclude the case that the
11021 last enabled row in the desired matrix touches the bottom boundary.
11023 2011-05-21 Glenn Morris <rgm@gnu.org>
11025 * Makefile.in ($(etc)/DOC): Make second command line even shorter.
11026 (SOME_MACHINE_OBJECTS): Replace FONT_OBJ by its maximal expansion,
11027 and add some more files.
11029 2011-05-20 Eli Zaretskii <eliz@gnu.org>
11031 * callproc.c (Fcall_process) [MSDOS]: Fix arguments to
11032 report_file_error introduced by the change from 2011-05-07.
11034 2011-05-20 Paul Eggert <eggert@cs.ucla.edu>
11036 * systime.h (Time): Define only if emacs is defined.
11037 This is to allow ../lib-src/profile.c to be compiled on FreeBSD,
11038 where the include path doesn't have X11/X.h by default. See
11039 <http://lists.gnu.org/archive/html/emacs-devel/2011-05/msg00561.html>.
11041 2011-05-20 Kenichi Handa <handa@m17n.org>
11043 * composite.c (find_automatic_composition): Fix previous change.
11045 2011-05-20 Glenn Morris <rgm@gnu.org>
11047 * lisp.mk: New file, split from Makefile.in.
11048 * Makefile.in (lisp): Move to separate file, inserted by @lisp_frag@.
11049 (shortlisp): Remove.
11050 ($(etc)/DOC): Edit lisp.mk rather than using $shortlisp.
11052 2011-05-19 Glenn Morris <rgm@gnu.org>
11054 * Makefile.in (MSDOS_SUPPORT_REAL, MSDOS_SUPPORT, NS_SUPPORT)
11055 (REAL_MOUSE_SUPPORT, GPM_MOUSE_SUPPORT, MOUSE_SUPPORT, TOOLTIP_SUPPORT)
11056 (BASE_WINDOW_SUPPORT, X_WINDOW_SUPPORT, WINDOW_SUPPORT): Remove.
11057 (lisp): Set the order to that of loadup.el.
11058 (shortlisp): Make it a copy of $lisp.
11059 (SOME_MACHINE_LISP): Remove.
11060 ($(etc)/DOC): Depend just on $lisp, not $SOME_MACHINE_LISP too.
11061 Use just $shortlisp, not $SOME_MACHINE_LISP too.
11063 2011-05-18 Kenichi Handa <handa@m17n.org>
11065 * composite.c (CHAR_COMPOSABLE_P): Add more check for efficiency.
11066 (BACKWARD_CHAR): Wrap the arg STOP by parenthesis.
11067 (find_automatic_composition): Mostly rewrite for efficiency.
11069 2011-05-18 Juanma Barranquero <lekktu@gmail.com>
11071 * makefile.w32-in: Update dependencies.
11073 2011-05-18 Christoph Scholtes <cschol2112@googlemail.com>
11075 * menu.c: Include limits.h (fixes the MS-Windows build broken by
11076 revision 104625).
11078 2011-05-18 Paul Eggert <eggert@cs.ucla.edu>
11080 Fix some integer overflow issues, such as string length overflow.
11082 * insdel.c (count_size_as_multibyte): Check for string overflow.
11084 * character.c (lisp_string_width): Check for string overflow.
11085 Use EMACS_INT, not int, for string indexes and lengths; in
11086 particular, 2nd arg is now EMACS_INT, not int. Do not crash if
11087 the resulting string length overflows an EMACS_INT; instead,
11088 report a string overflow if no precision given. When checking for
11089 precision exhaustion, use a check that cannot possibly have
11090 integer overflow. (Bug#8675)
11091 * character.h (lisp_string_width): Adjust to new signature.
11093 * alloc.c (string_overflow): New function.
11094 (Fmake_string): Use it. This doesn't change behavior, but saves
11095 a few bytes and will simplify future changes.
11096 * character.c (string_escape_byte8): Likewise.
11097 * lisp.h (string_overflow): New decl.
11099 Fixups, following up to the user-interface timestamp change.
11100 * nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
11101 for UI timestamps, instead of unsigned long.
11102 * msdos.c (mouse_get_pos): Likewise.
11103 * w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
11104 * w32gui.h (Time): Define by including "systime.h" rather than by
11105 declaring it ourselves. (Bug#8664)
11107 * dispextern.h (struct image): Don't assume time_t <= unsigned long.
11108 * image.c (clear_image_cache): Likewise.
11110 * term.c (term_mouse_position): Don't assume time_t wraparound.
11112 Be more systematic about user-interface timestamps.
11113 Before, the code sometimes used 'Time', sometimes 'unsigned long',
11114 and sometimes 'EMACS_UINT', to represent these timestamps.
11115 This change causes it to use 'Time' uniformly, as that's what X uses.
11116 This makes the code easier to follow, and makes it easier to catch
11117 integer overflow bugs such as Bug#8664.
11118 * frame.c (Fmouse_position, Fmouse_pixel_position):
11119 Use Time, not unsigned long, for user-interface timestamps.
11120 * keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
11121 (button_down_time, make_lispy_position, make_lispy_movement): Likewise.
11122 * keyboard.h (last_event_timestamp): Likewise.
11123 * menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
11124 * menu.h (xmenu_show): Likewise.
11125 * term.c (term_mouse_position): Likewise.
11126 * termhooks.h (struct input_event.timestamp): Likewise.
11127 (struct terminal.mouse_position_hook): Likewise.
11128 * xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
11129 * xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
11130 * systime.h (Time): New decl. Pull it in from <X11/X.h> if
11131 HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
11132 what it was before.
11133 * menu.h, termhooks.h: Include "systime.h", for Time.
11135 * keyboard.c (make_lispy_event): Fix problem in integer overflow.
11136 Don't assume that the difference between two unsigned long values
11137 can fit into an integer. At this point, we know button_down_time
11138 <= event->timestamp, so the difference must be nonnegative, so
11139 there's no need to cast the result if double-click-time is
11140 nonnegative, as it should be; check that it's nonnegative, just in
11141 case. This bug is triggered when events are more than 2**31 ms
11142 apart (about 25 days). (Bug#8664)
11144 * xselect.c (last_event_timestamp): Remove duplicate decl.
11145 (x_own_selection): Remove needless cast to unsigned long.
11147 * xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
11148 that always fit in int. Use a sentinel instead of a counter, to
11149 avoid a temp and to allay GCC's concerns about possible int overflow.
11150 * frame.h (struct frame): Use int for menu_bar_items_used
11151 instead of EMACS_INT, since it always fits in int.
11153 * menu.c (grow_menu_items): Check for int overflow.
11155 * xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.
11157 * xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
11158 Before, the code was not consistent. These values cannot exceed
11159 2**31 - 1 so there's no need to make them unsigned.
11160 (x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
11161 (x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
11162 (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
11163 as modifiers.
11164 * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
11166 * lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
11167 (XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
11168 Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
11169 presumably because the widths might not match.
11171 * window.c (size_window): Avoid needless test at loop start.
11173 2011-05-18 Courtney Bane <emacs-bugs-7626@cbane.org> (tiny change)
11175 * term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).
11177 2011-05-12 Drew Adams <drew.adams@oracle.com>
11179 * textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).
11181 2011-05-12 YAMAMOTO Mitsuharu <mituharu@math.s.chiba-u.ac.jp>
11183 * w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
11184 `width' to `bar_area_x' and `bar_area_width', respectively.
11185 (x_scroll_run): Take account of fringe background extension.
11187 * xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
11188 Rename local vars `left' and `width' to `bar_area_x' and
11189 `bar_area_width', respectively.
11190 (x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
11191 background extension.
11193 2011-05-10 Jim Meyering <meyering@redhat.com>
11195 * xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".
11197 2011-05-10 Juanma Barranquero <lekktu@gmail.com>
11199 * image.c (Finit_image_library): Return t for built-in image types,
11200 like pbm and xbm. (Bug#8640)
11202 2011-05-09 Andreas Schwab <schwab@linux-m68k.org>
11204 * w32menu.c (set_frame_menubar): Fix submenu allocation.
11206 2011-05-07 Eli Zaretskii <eliz@gnu.org>
11208 * w32console.c (Fset_screen_color): Doc fix.
11209 (Fget_screen_color): New function.
11210 (syms_of_ntterm): Defsubr it.
11212 * callproc.c (call_process_cleanup) [MSDOS]: Don't close and
11213 unlink the temporary file if Fcall_process didn't create it in the
11214 first place.
11215 (Fcall_process) [MSDOS]: Don't create tempfile if stdout of the
11216 child process will be redirected to a file specified with `:file'.
11217 Don't try to re-open tempfile in that case, and set fd[0] to -1 as
11218 cue to call_process_cleanup not to close that handle.
11220 2011-05-07 Ben Key <bkey76@gmail.com>
11222 * makefile.w32-in: The bootstrap-temacs rule now makes use of
11223 one of two shell specific rules, either bootstrap-temacs-CMD or
11224 bootstrap-temacs-SH. The bootstrap-temacs-SH rule is identical
11225 to the previous implementation of the bootstrap-temacs rule.
11226 The bootstrap-temacs-CMD rule is similar to the previous
11227 implementation of the bootstrap-temacs rule except that it
11228 makes use of the ESC_CFLAGS variable instead of the CFLAGS
11229 variable.
11231 These changes, along with some changes to nt/configure.bat,
11232 nt/gmake.defs, and nt/nmake.defs, are required to extend my
11233 earlier fix to add support for --cflags and --ldflags options
11234 that include quotes so that it works whether make uses cmd or
11235 sh as the shell.
11237 2011-05-06 Michael Albinus <michael.albinus@gmx.de>
11239 * dbusbind.c (QCdbus_type_unix_fd): Declare static.
11240 (xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
11241 is a constant.
11242 (Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
11243 a string. Handle both cases.
11244 (Fdbus_call_method_asynchronously, Fdbus_register_signal)
11245 (Fdbus_register_method): Use Qinvalid_function.
11247 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
11249 * makefile.w32-in: Update dependencies.
11250 (LISP_H): Add inttypes.h and stdin.h.
11251 (PROCESS_H): Add unistd.h.
11253 2011-05-06 Eli Zaretskii <eliz@gnu.org>
11255 * lread.c: Include limits.h (fixes the MS-Windows build broken by
11256 revision 104134).
11258 2011-05-06 Paul Eggert <eggert@cs.ucla.edu>
11260 * image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.
11262 * term.c (vfatal): Remove stray call to va_end.
11263 It's not needed and the C Standard doesn't allow it here anyway.
11265 Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
11266 * eval.c (verror): doprnt a copy of ap, not the original. (Bug#8545)
11268 * eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
11269 bytes.
11271 * term.c: Don't include <stdarg.h>, as <lisp.h> does that.
11273 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.
11275 * process.c (Fformat_network_address): Fix typo: args2 -> *args2.
11277 * xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).
11279 * coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).
11281 * charset.h (struct charset.code_space): Now has 15 elements, not 16.
11282 * charset.c (Fdefine_charset_internal): Don't initialize
11283 charset.code_space[15]. The value was garbage, on hosts with
11284 32-bit int (Bug#8600).
11286 * lread.c (read_integer): Be more consistent with string-to-number.
11287 Use string_to_number to do the actual conversion; this avoids
11288 rounding errors and fixes some other screwups. Without this fix,
11289 for example, #x1fffffffffffffff was misread as -2305843009213693952.
11290 (digit_to_number): Move earlier, for benefit of read_integer.
11291 Return -1 if the digit is out of range for the base, -2 if it is
11292 not a digit in any supported base. (Bug#8602)
11294 * doprnt.c (doprnt): Support arbitrary pI values, such as "I64".
11296 * dispnew.c (scrolling_window): Return 1 if we scrolled,
11297 to match comment at start of function. This also removes a
11298 GCC warning about overflow in a 32+64-bit port.
11300 * lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.
11302 * dbusbind.c: Do not use XPNTR on a value that may be an integer.
11303 Reported by Stefan Monnier in
11304 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
11305 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
11306 Use SYMBOLP-guarded XSYMBOL, not XPNTR.
11308 * lisp.h (EMACS_INTPTR): Remove. All uses changed to intptr_t.
11309 (EMACS_UINTPTR): Likewise, with uintptr_t.
11311 * lisp.h: Prefer 64-bit EMACS_INT if available.
11312 (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
11313 on 32-bit hosts that have 64-bit int, so that they can access
11314 large files.
11315 However, temporarily disable this change unless the temporary
11316 symbol WIDE_EMACS_INT is defined.
11318 * lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.
11320 Prefer intptr_t/uintptr_t for integers the same widths as pointers.
11321 This removes an assumption that EMACS_INT and long are the same
11322 width as pointers. The assumption is true for Emacs porting targets
11323 now, but we want to make other targets possible.
11324 * lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
11325 (EMACS_INTPTR, EMACS_UINTPTR): New macros.
11326 In the rest of the code, change types of integers that hold casted
11327 pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
11328 replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
11329 (XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
11330 (XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
11331 No need to cast type when ORing.
11332 (XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
11333 * alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
11334 * doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
11335 assume EMACS_INT is the same width as char *.
11336 * gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
11337 (xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
11338 Remove no-longer-needed casts.
11339 (xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
11340 (xg_tool_bar_help_callback, xg_make_tool_item):
11341 Use EMACS_INTPTR to hold an integer
11342 that will be cast to void *; this can avoid a GCC warning
11343 if EMACS_INT is not the same width as void *.
11344 * menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
11345 * xdisp.c (display_echo_area_1, resize_mini_window_1):
11346 (current_message_1, set_message_1):
11347 Use a local to convert to proper width without a cast.
11348 * xmenu.c (dialog_selection_callback): Likewise.
11350 * sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
11351 Also, don't assume VALBITS / RAND_BITS is less than 5,
11352 and don't rely on undefined behavior when shifting a 1 left into
11353 the sign bit.
11354 * lisp.h (get_random): Change signature to match.
11356 * lread.c (hash_string): Use size_t, not int, for hash computation.
11357 Normally we prefer signed values; but hashing is special, because
11358 it's better to use unsigned division on hash table sizes so that
11359 the remainder is nonnegative. Also, size_t is the natural width
11360 for hashing into memory. The previous code used 'int', which doesn't
11361 retain enough info to hash well into very large tables.
11362 (oblookup, oblookup_last_bucket_number, Funintern): Likewise.
11364 * dbusbind.c: Don't possibly lose pointer info when converting.
11365 (xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
11366 Use XPNTR rather than XHASH, so that the high-order bits of
11367 the pointer aren't lost when converting through void *.
11369 * eval.c (Fautoload): Don't double-shift a pointer.
11371 * fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.
11373 2011-05-06 Juanma Barranquero <lekktu@gmail.com>
11375 * gnutls.c (DEF_GNUTLS_FN):
11376 * image.c (DEF_IMGLIB_FN): Make function pointers static.
11378 2011-05-05 Andreas Schwab <schwab@linux-m68k.org>
11380 * lread.c (lisp_file_lexically_bound_p): Stop scanning at end
11381 marker. (Bug#8610)
11383 2011-05-05 Eli Zaretskii <eliz@gnu.org>
11385 * w32heap.c (allocate_heap) [USE_LISP_UNION_TYPE || USE_LSB_TAG]:
11386 New version that can reserve upto 2GB of heap space.
11388 2011-05-05 Chong Yidong <cyd@stupidchicken.com>
11390 * nsfns.m (Fns_read_file_name): Doc fix (Bug#8534).
11392 2011-05-05 Teodor Zlatanov <tzz@lifelogs.com>
11394 * gnutls.c (fn_gnutls_certificate_set_x509_key_file): Add alias to
11395 `gnutls_certificate_set_x509_key_file'.
11397 2011-05-05 Juanma Barranquero <lekktu@gmail.com>
11399 * makefile.w32-in ($(BLD)/image.$(O), $(BLD)/process.$(O)):
11400 Update dependencies.
11402 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
11404 * gnutls.h (emacs_gnutls_write, emacs_gnutls_read):
11405 * gnutls.c (emacs_gnutls_write, emacs_gnutls_read):
11406 Remove unused parameter `fildes'.
11407 * process.c (read_process_output, send_process): Don't pass it.
11409 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
11411 Fix previous change: the library cache is defined in w32.c.
11412 * image.c (CACHE_IMAGE_TYPE) [!HAVE_NTGUI]: Define to noop.
11413 (Finit_image_library): Wrap Vlibrary_cache on "#ifdef HAVE_NTGUI".
11415 2011-05-04 Juanma Barranquero <lekktu@gmail.com>
11417 Implement dynamic loading of GnuTLS on Windows.
11419 * gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
11420 (emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
11421 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
11422 Declare.
11424 * gnutls.c (Qgnutls_dll): Define.
11425 (DEF_GNUTLS_FN, LOAD_GNUTLS_FN): New macros.
11426 (gnutls_*): Declare function pointers.
11427 (init_gnutls_functions): New function to initialize function pointers.
11428 (emacs_gnutls_handshake, Fgnutls_error_string, Fgnutls_deinit)
11429 (emacs_gnutls_global_init, Fgnutls_bye): Use function pointers.
11430 (emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
11431 Wrappers for gnutls_record_check_pending and gnutls_transport_set_errno.
11432 (emacs_gnutls_write, emacs_gnutls_read)
11433 (emacs_gnutls_handle_error, Fgnutls_error_fatalp)
11434 (Fgnutls_available_p): New function.
11435 (Fgnutls_boot): Call Fgnutls_available_p. Use function pointers.
11436 (syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
11437 (syms_of_gnutls) <Sgnutls_available_p>: defsubr it.
11439 * image.c: Include w32.h.
11440 (Vimage_type_cache): Delete.
11441 (syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
11442 (CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.
11443 (w32_delayed_load): Move to w32.c.
11445 * w32.h (VlibraryCache, QCloaded_from, w32_delayed_load): Declare.
11447 * w32.c (QCloaded_from, Vlibrary_cache): Define.
11448 (w32_delayed_load): Move from image.c. When loading a library, record
11449 its filename in the :loaded-from property of the library id.
11450 (globals_of_w32) <QCloaded_from, Vlibrary_cache>:
11451 Initialize and staticpro them.
11452 (emacs_gnutls_pull, emacs_gnutls_push): Call emacs_gnutls_* functions.
11454 * process.c: Include lisp.h before w32.h, not after.
11455 (wait_reading_process_output): Call emacs_gnutls_record_check_pending
11456 instead of gnutls_record_check_pending.
11458 * callproc.c, emacs.c: Include lisp.h before w32.h, not after.
11460 2011-05-04 Teodor Zlatanov <tzz@lifelogs.com>
11462 * gnutls.c (Fgnutls_boot): Support :keylist and :crlfiles options
11463 instead of :keyfiles. Give GnuTLS the keylist and the CRL lists
11464 as passed in.
11466 2011-05-03 Jan Djärv <jan.h.d@swipnet.se>
11468 * xterm.c (x_set_frame_alpha): Do not set property on anything
11469 else than FRAME_X_OUTER_WINDOW (Bug#8608).
11471 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
11473 * sysdep.c (get_tty_size) [WINDOWSNT]: Implement. (Bug#8596)
11475 2011-05-02 Juanma Barranquero <lekktu@gmail.com>
11477 * gnutls.c (Qgnutls_log_level, Qgnutls_code, Qgnutls_anon)
11478 (Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)

11482 (Qgnutls_bootprop_callbacks, Qgnutls_bootprop_loglevel)
11483 (Qgnutls_bootprop_hostname, Qgnutls_bootprop_verify_flags)
11484 (Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
11485 (Qgnutls_bootprop_callbacks_verify): Make static.
11487 2011-05-01 Andreas Schwab <schwab@linux-m68k.org>
11489 * callproc.c: Indentation fixup.
11491 * sysdep.c (wait_for_termination_1): Make static.
11492 (wait_for_termination, interruptible_wait_for_termination):
11493 Move after wait_for_termination_1.
11495 2011-05-01 Lars Magne Ingebrigtsen <larsi@gnus.org>
11497 * sysdep.c (interruptible_wait_for_termination): New function
11498 which is like wait_for_termination, but allows keyboard
11499 interruptions.
11501 * callproc.c (Fcall_process): Add (:file "file") as an option for
11502 the STDOUT buffer.
11503 (Fcall_process_region): Ditto.
11505 2011-04-30 Eli Zaretskii <eliz@gnu.org>
11507 * dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
11508 rather than `XVECTOR (FOO)->size'.
11510 * process.c: Remove HAVE_INTTYPES_H condition from inclusion of
11511 inttypes.h, as a gnulib replacement is used if it not available in
11512 system headers.
11514 2011-04-21 Eli Zaretskii <eliz@gnu.org>
11516 Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
11517 * fileio.c (Finsert_file_contents): Don't limit file size to 1/4
11518 of MOST_POSITIVE_FIXNUM. (Bug#8528)
11520 * coding.c (coding_alloc_by_realloc): Error out if destination
11521 will grow beyond MOST_POSITIVE_FIXNUM.
11522 (decode_coding_emacs_mule): Abort if there isn't enough place in
11523 charbuf for the composition carryover bytes. Reserve an extra
11524 space for up to 2 characters produced in a loop.
11525 (decode_coding_iso_2022): Abort if there isn't enough place in
11526 charbuf for the composition carryover bytes.
11528 2011-04-21 Eli Zaretskii <eliz@gnu.org>
11530 * doprnt.c (doprnt) [!HAVE_LONG_LONG_INT]: Error out instead of
11531 aborting when %lld or %lll format is passed.
11532 [!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
11533 %llo or %llx format is passed. (Bug#8545)
11535 * window.c (window_scroll_line_based): Use a marker instead of
11536 simple variables to record original value of point. (Bug#7952)
11538 * doprnt.c (doprnt): Fix the case where a multibyte sequence
11539 produced by %s or %c overflows available buffer space. (Bug#8545)
11541 2011-04-28 Paul Eggert <eggert@cs.ucla.edu>
11543 * doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).
11544 (SIZE_MAX): Move defn after all includes, as they might #define it.
11546 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
11548 * w32.c (init_environment): Warn about defaulting HOME to C:\.
11550 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
11552 * keyboard.c (Qdelayed_warnings_hook): Define.
11553 (command_loop_1): Run `delayed-warnings-hook'
11554 if Vdelayed_warnings_list is non-nil.
11555 (syms_of_keyboard) <delayed-warnings-hook>: DEFSYM it.
11556 (syms_of_keyboard) <delayed-warnings-list>: DEFVAR_LISP it.
11558 2011-04-28 Eli Zaretskii <eliz@gnu.org>
11560 * doprnt.c (doprnt): Don't return value smaller than the buffer
11561 size if the message was truncated. (Bug#8545).
11563 2011-04-28 Juanma Barranquero <lekktu@gmail.com>
11565 * w32fns.c (Fx_change_window_property, Fx_delete_window_property)
11566 (Fx_window_property): #if-0 the whole functions, not just the bodies.
11568 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
11570 * doprnt.c (doprnt): Support "ll" length modifier, for long long.
11572 2011-04-27 Juanma Barranquero <lekktu@gmail.com>
11574 * makefile.w32-in: Update dependencies.
11576 2011-04-27 Eli Zaretskii <eliz@gnu.org>
11578 Improve `doprnt' and its usage. (Bug#8545)
11579 * doprnt.c (doprnt): Make sure `format' is never accessed beyond
11580 `format_end'. Remove support for %l as a conversion specifier.
11581 Don't use xrealloc. Improve diagnostics when the %l size modifier
11582 is used. Update the commentary.
11584 * eval.c (verror): Simplify calculation of size_t.
11586 * coding.c (Ffind_operation_coding_system): Fix diagnostic error
11587 messages.
11589 2011-04-27 Yoshiaki Kasahara <kasahara@nc.kyushu-u.ac.jp> (tiny change)
11591 * buffer.c (init_buffer) [USE_MMAP_FOR_BUFFERS]: Adjust to aliasing
11592 change.
11594 2011-04-27 Paul Eggert <eggert@cs.ucla.edu>
11596 * nsmenu.m: Replace all uses of XVECTOR with ASIZE and AREF.
11597 This makes this file independent of the recent pseudovector change.
11599 2011-04-26 Paul Eggert <eggert@cs.ucla.edu>
11601 * keyboard.c (handle_user_signal): Fix pointer signedness problem.
11603 * gnutls.c (emacs_gnutls_handle_error): Remove unused local.
11604 (Fgnutls_boot): gnutls_certificate_verify_peers2 wants unsigned *.
11605 Remove unused local.
11606 (emacs_gnutls_write): Don't use uninitialized rtnval if nbyte <= 0.
11608 * lisp.h: Fix a problem with aliasing and vector headers. (Bug#8546)
11609 GCC 4.6.0 optimizes based on type-based alias analysis.
11610 For example, if b is of type struct buffer * and v of type struct
11611 Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
11612 != &v->size, and therefore "v->size = 1; b->size = 2; return
11613 v->size;" must therefore return 1. This assumption is incorrect
11614 for Emacs, since it type-puns struct Lisp_Vector * with many other
11615 types. To fix this problem, this patch adds a new type struct
11616 vectorlike_header that documents the constraints on layout of vectors
11617 and pseudovectors, and helps optimizing compilers not get fooled
11618 by Emacs's type punning. It also adds the macros XSETTYPED_PVECTYPE
11619 XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.
11620 * lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
11621 the size member.
11622 (XSETPVECTYPE): Rewrite in terms of new macro.
11623 (XSETPVECTYPESIZE): New macro, specifying both type and size.
11624 This is a bit clearer, and further avoids the possibility of
11625 undesirable aliasing.
11626 (XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.
11627 (XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.
11628 (XSETSUBR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR and XSIZE,
11629 since Lisp_Subr is a special case (no "next" field).
11630 (ASIZE): Now uses header.size rather than size.
11631 All previous uses of XVECTOR (foo)->size replaced to use this macro,
11632 to avoid the hassle of writing XVECTOR (foo)->header.size.
11633 (struct vectorlike_header): New type.
11634 (TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
11635 object, to help avoid aliasing.
11636 (PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
11637 (SUBRP): Likewise, since Lisp_Subr is a special case.
11638 * lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
11639 (struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
11640 (struct Lisp_Hash_Table): Combine first two members into a single
11641 struct vectorlike_header member. All uses of "size" and "next" members
11642 changed to be "header.size" and "header.next".
11643 * buffer.h (struct buffer): Likewise.
11644 * font.h (struct font_spec, struct font_entity, struct font): Likewise.
11645 * frame.h (struct frame): Likewise.
11646 * process.h (struct Lisp_Process): Likewise.
11647 * termhooks.h (struct terminal): Likewise.
11648 * window.c (struct save_window_data, struct saved_window): Likewise.
11649 * window.h (struct window): Likewise.
11650 * alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
11651 Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
11652 * buffer.c (init_buffer_once): Likewise.
11653 * lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a
11654 special case.
11655 * process.c (Fformat_network_address): Use local var for size,
11656 for brevity.
11658 * bytecode.c (exec_byte_code): Don't use XVECTOR before CHECK_VECTOR.
11660 Make the Lisp reader and string-to-float more consistent (Bug#8525)
11661 * data.c (atof): Remove decl; no longer used or needed.
11662 (digit_to_number): Move to lread.c.
11663 (Fstring_to_number): Use new string_to_number function, to be
11664 consistent with how the Lisp reader treats infinities and NaNs.
11665 Do not assume that floating-point numbers represent EMACS_INT
11666 without losing information; this is not true on most 64-bit hosts.
11667 Avoid double-rounding errors, by insisting on integers when
11668 parsing non-base-10 numbers, as the documentation specifies.
11669 * lisp.h (string_to_number): New decl, replacing ...
11670 (isfloat_string): Remove.
11671 * lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
11672 (read1): Do not accept +. and -. as integers; this
11673 appears to have been a coding error. Similarly, do not accept
11674 strings like +-1e0 as floating point numbers. Do not report
11675 overflow for integer overflows unless the base is not 10 which
11676 means we have no simple and reliable way to continue.
11677 Break out the floating-point parsing into a new
11678 function string_to_number, so that Fstring_to_number parses
11679 floating point numbers consistently with the Lisp reader.
11680 (digit_to_number): Move here from data.c. Make it static inline.
11681 (E_CHAR, EXP_INT): Remove, replacing with ...
11682 (E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
11683 (string_to_number): New function, replacing isfloat_string.
11684 This function checks for valid syntax and produces the resulting
11685 Lisp float number too. Rework it so that string-to-number
11686 no longer mishandles examples like "1.0e+". Use strtoumax,
11687 so that overflow for non-base-10 numbers is reported only when
11688 there's no portable and simple way to convert to floating point.
11690 * textprop.c (set_text_properties_1): Rewrite for clarity,
11691 and to avoid GCC warning about integer overflow.
11693 * intervals.h (struct interval): Use EMACS_INT for members
11694 where EMACS_UINT might cause problems. See
11695 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
11696 (CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
11697 * intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
11698 All uses changed.
11699 (offset_intervals): Tell GCC not to worry about length overflow
11700 when negating a negative length.
11702 * alloc.c (overrun_check_malloc, overrun_check_realloc): Now static.
11703 (overrun_check_free): Likewise.
11705 * alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
11706 in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
11707 word size.
11709 * gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
11710 (gnutls_make_error): Rename local to avoid shadowing.
11711 (gnutls_emacs_global_deinit): ifdef out; not used.
11712 (Fgnutls_boot): Use const for pointer to readonly storage.
11713 Comment out unused local. Fix pointer signedness problems.
11715 * lread.c (openp): Don't stuff size_t into an 'int'.
11716 Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
11717 about possible signed overflow.
11719 * gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
11720 (GDK_KEY_g): Don't define if already defined.
11721 (xg_prepare_tooltip): Avoid pointer signedness problem.
11722 (xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.
11724 * process.c (Fnetwork_interface_info): Avoid left-shift undefined
11725 behavior with 1 << 31. GCC 4.6.0 warns about this on 32-bit hosts.
11727 * xfns.c (Fx_window_property): Simplify a bit,
11728 to make a bit faster and to avoid GCC 4.6.0 warning.
11729 * xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.
11731 * fns.c (internal_equal): Don't assume size_t fits in int.
11733 * alloc.c (compact_small_strings): Tighten assertion a little.
11735 Replace pEd with more-general pI, and fix some printf arg casts.
11736 * lisp.h (pI): New macro, generalizing old pEd macro to other
11737 conversion specifiers. For example, use "...%"pI"d..." rather
11738 than "...%"pEd"...".
11739 (pEd): Remove. All uses replaced with similar uses of pI.
11740 * m/amdx86-64.h, m/ia64.h, m/ibms390x.h: Likewise.
11741 * alloc.c (check_pure_size): Don't overflow by converting size to int.
11742 * bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
11743 * data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
11744 * dbusbind.c (xd_append_arg): Use pI to avoid cast.
11745 (Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.
11746 * font.c (font_unparse_xlfd): Avoid potential buffer overrun on
11747 64-bit hosts.
11748 (font_unparse_xlfd, font_unparse_fcname): Use pI to avoid casts.
11749 * keyboard.c (record_char, modify_event_symbol): Use pI to avoid casts.
11750 * print.c (safe_debug_print, print_object): Likewise.
11751 (print_object): Don't overflow by converting EMACS_INT or EMACS_UINT
11752 to int.
11753 Use pI instead of if-then-else-abort. Use %p to avoid casts,
11754 avoiding the 0 flag, which is not portable.
11755 * process.c (Fmake_network_process): Use pI to avoid cast.
11756 * region-cache.c (pp_cache): Likewise.
11757 * xdisp.c (decode_mode_spec): Likewise.
11758 * xrdb.c (x_load_resources) [USE_MOTIF]: Use pI to avoid undefined
11759 behavior on 64-bit hosts with printf arg.
11760 * xselect.c (x_queue_event): Use %p to avoid casts, avoiding 0 flag.
11761 (x_stop_queuing_selection_requests): Likewise.
11762 (x_get_window_property): Don't truncate byte count to an 'int'
11763 when tracing.
11765 * frame.c (frame_name_fnn_p): Get rid of strtol, which isn't right
11766 here, since it parses constructs like leading '-' and spaces,
11767 which are not wanted; and it overflows with large numbers.
11768 Instead, simply match F[0-9]+, which is what is wanted anyway.
11770 * alloc.c: Remove unportable assumptions about struct layout.
11771 (SDATA_SELECTOR, SDATA_DATA_OFFSET): New macros.
11772 (SDATA_OF_STRING, SDATA_SIZE, allocate_string_data):
11773 (allocate_vectorlike, make_pure_vector): Use the new macros,
11774 plus offsetof, to remove unportable assumptions about struct layout.
11775 These assumptions hold on all porting targets that I know of, but
11776 they are not guaranteed, they're easy to remove, and removing them
11777 makes further changes easier.
11779 * alloc.c (BLOCK BYTES): Fix typo by changing "ablock" to "ablocks".
11780 This doesn't fix a bug but makes the code clearer.
11781 (string_overrun_cookie): Now const. Use initializers that
11782 don't formally overflow signed char, to avoid warnings.
11783 (allocate_string_data) [GC_CHECK_STRING_OVERRUN]: Fix typo that
11784 can cause Emacs to crash when string overrun checking is enabled.
11785 (allocate_buffer): Don't assume sizeof (struct buffer) is a
11786 multiple of sizeof (EMACS_INT); it need not be, if
11787 alignof(EMACS_INT) < sizeof (EMACS_INT).
11788 (check_sblock, check_string_bytes, check_string_free_list): Protoize.
11790 2011-04-26 Juanma Barranquero <lekktu@gmail.com>
11792 * keyboard.c (QCrtl): Rename from Qrtl. All uses changed.
11794 2011-04-26 Teodor Zlatanov <tzz@lifelogs.com>
11796 * gnutls.c (emacs_gnutls_handshake): Return an error if we're not
11797 supposed to be handshaking. (Bug#8556)
11798 Reported by Paul Eggert <eggert@cs.ucla.edu>.
11800 2011-04-26 Daniel Colascione <dan.colascione@gmail.com>
11802 * lisp.h (Qdebug): List symbol.
11803 * eval.c (Qdebug): Restore global linkage.
11804 * keyboard.c (debug-on-event): New variable.
11805 (handle_user_signal): Break into debugger when debug-on-event
11806 matches the current signal symbol.
11808 2011-04-25 Dan Nicolaescu <dann@ics.uci.edu>
11810 * alloc.c (check_sblock, check_string_bytes)
11811 (check_string_free_list): Convert to standard C.
11813 2011-04-25 Teodor Zlatanov <tzz@lifelogs.com>
11815 * w32.c (emacs_gnutls_push): Fix typo.
11817 2011-04-25 Eli Zaretskii <eliz@gnu.org>
11819 * gnutls.c (emacs_gnutls_handshake): Avoid compiler warnings about
11820 "cast to pointer from integer of different size".
11822 Improve doprnt and its use in verror. (Bug#8545)
11823 * doprnt.c (doprnt): Document the set of format control sequences
11824 supported by the function. Use SAFE_ALLOCA instead of always
11825 using `alloca'.
11827 * eval.c (verror): Don't limit the buffer size at size_max-1, that
11828 is one byte too soon. Don't use xrealloc; instead xfree and
11829 xmalloc anew.
11831 2011-04-24 Teodor Zlatanov <tzz@lifelogs.com>
11833 * gnutls.h: Add GNUTLS_STAGE_CALLBACKS enum to denote we're in the
11834 callbacks stage.
11836 * gnutls.c: Renamed global_initialized to
11837 gnutls_global_initialized. Added internals for the
11838 :verify-hostname-error, :verify-error, and :verify-flags
11839 parameters of `gnutls-boot' and documented those parameters in the
11840 docstring. Start callback support.
11841 (emacs_gnutls_handshake): Add Woe32 support. Retry handshake
11842 unless a fatal error occurred. Call gnutls_alert_send_appropriate
11843 on error. Return error code.
11844 (emacs_gnutls_write): Call emacs_gnutls_handle_error.
11845 (emacs_gnutls_read): Likewise.
11846 (Fgnutls_boot): Return handshake error code.
11847 (emacs_gnutls_handle_error): New function.
11848 (wsaerror_to_errno): Likewise.

11851 (emacs_gnutls_push): Likewise.
11853 * w32.c (emacs_gnutls_pull): New function for GnuTLS on Woe32.
11854 (emacs_gnutls_push): Likewise.
11856 2011-04-24 Claudio Bley <claudio.bley@gmail.com> (tiny change)
11858 * process.c (wait_reading_process_output): Check if GnuTLS
11859 buffered some data internally if no FDs are set for TLS
11860 connections.
11862 * makefile.w32-in (OBJ2): Add gnutls.$(O).
11863 (LIBS): Link to USER_LIBS.

11868 * xdisp.c (handle_single_display_spec): Rename the
11869 display_replaced_before_p argument into display_replaced_p, to
11870 make it consistent with the commentary. Fix typos in the
11871 commentary.
11873 * textprop.c (syms_of_textprop): Remove dead code.
11874 (copy_text_properties): Delete obsolete commentary about an
11875 interface that was deleted long ago. Fix typos in the description
11876 of arguments.
11878 * msdos.c (XMenuActivate, XMenuAddSelection): Adjust argument list
11879 to changes in oldXMenu/XMenu.h from 2011-04-16.
11880 <menu_help_message, prev_menu_help_message>: Constify.
11881 (IT_menu_make_room): menu->help_text is now `const char **';
11882 adjust.
11884 * msdos.h (XMenuActivate, XMenuAddSelection): Adjust prototypes
11885 to changes in oldXMenu/XMenu.h from 2011-04-16.
11886 (struct XMenu): Declare `help_text' `const char **'.
11888 * xfaces.c <Qunspecified>: Make extern again.
11890 * syntax.c: Include sys/types.h before including regex.h, as
11891 required by POSIX.
11893 * doc.c (get_doc_string): Improve the format passed to `error'.
11895 * doprnt.c (doprnt): Improve commentary.
11897 * term.c (init_tty) [MSDOS]: Fix 1st argument to maybe_fatal.
11899 * Makefile.in (TAGS): Depend on $(M_FILE) and $(S_FILE), and scan
11900 them with etags.
11902 * makefile.w32-in (globals.h): Add a dummy recipe, to make any
11903 changes in globals.h immediately force recompilation.
11904 (TAGS): Depend on $(CURDIR)/m/intel386.h and
11905 $(CURDIR)/s/ms-w32.h.
11906 (TAGS-gmake): Scan $(CURDIR)/m/intel386.h and $(CURDIR)/s/ms-w32.h.
11908 * character.c (Fchar_direction): Function deleted.
11909 (syms_of_character): Don't defsubr it.
11910 <char-direction-table>: Deleted.
11912 2011-04-23 Eli Zaretskii <eliz@gnu.org>
11914 Fix doprnt so it could be used again safely in `verror'. (Bug#8435)
11915 * doprnt.c: Include limits.h.
11916 (SIZE_MAX): New macro.
11917 (doprnt): Return a size_t value. 2nd arg is now size_t.
11918 Many local variables are now size_t instead of int or unsigned.
11919 Improve overflow protection. Support `l' modifier for integer
11920 conversions. Support %l conversion. Don't assume an EMACS_INT
11921 argument for integer conversions and for %c.
11923 * lisp.h (doprnt): Restore prototype.
11925 * makefile.w32-in ($(BLD)/callint.$(O)): Depend on
11926 $(SRC)/character.h.
11928 * Makefile.in (base_obj): Add back doprnt.o.
11930 * deps.mk (doprnt.o): Add back prerequisites.
11931 (callint.o): Depend on character.h.
11933 * eval.c (internal_lisp_condition_case): Include the handler
11934 representation in the error message.
11935 (verror): Call doprnt instead of vsnprintf. Fix an off-by-one bug
11936 when breaking from the loop.
11938 * xdisp.c (vmessage): Call doprnt instead of vsnprintf.
11940 * callint.c (Fcall_interactively): When displaying error message
11941 about invalid control letter, pass the character's codepoint, not
11942 a pointer to its multibyte form. Improve display of the character
11943 in octal and display also its hex code.
11945 * character.c (char_string): Use %x to display the (unsigned)
11946 codepoint of an invalid character, to avoid displaying a bogus
11947 negative value.
11949 * font.c (check_otf_features): Pass SDATA of SYMBOL_NAME to
11950 `error', not SYMBOL_NAME itself.
11952 * coding.c (Fencode_sjis_char, Fencode_big5_char): Use %c for
11953 character arguments to `error'.
11955 * charset.c (check_iso_charset_parameter): Fix incorrect argument
11956 to `error' in error message about FINAL_CHAR argument. Make sure

12507 so that it's not optimized away.
12508 (bidi_ignore_explicit_marks_for_paragraph_level): Likewise.
12509 * dispextern.h (bidi_dump_cached_states): Remove, since it's
12510 exported only to the debugger.

12515 font.c: Make copy_font_spec and merge_font_spec ordinary C functions.

12522 * lisp.h (suppress_checking, die): Declare only if ENABLE_CHECKING
12523 is defined.

12539 * xdisp.c (message_enable_multibyte): Now static.
12541 Declare Lisp_Object Q* variables to be 'static' if not exported.
12542 This makes it easier for human readers (and static analyzers)
12543 to see whether these variables are used from other modules.
12544 * alloc.c, buffer.c, bytecode.c, callint.c, casetab.c, category.c:

12554 Remove decls of unexported vars.
12555 * keyboard.h (EVENT_HEAD_UNMODIFIED): Remove now-unused macro.
12557 * lisp.h (DEFINE_FUNC): Make sname 'static'.
12559 Make Emacs functions such as Fatom 'static' by default.
12560 This makes it easier for human readers (and static analyzers)
12561 to see whether these functions can be called from other modules.
12562 DEFUN now defines a static function. To make the function external
12563 so that it can be used in other C modules, use the new macro DEFUE.
12564 * lisp.h (Funibyte_char_to_multibyte, Fsyntax_table_p):
12565 (Finit_image_library):
12566 (Feval_region, Fbacktrace, Ffetch_bytecode, Fswitch_to_buffer):

12568 (Fget_process, Fdocumentation_property, Fbyte_code, Ffile_attributes):
12569 Remove decls, since these functions are now static.
12570 (Funintern, Fget_internal_run_time): New decls, since these functions
12571 were already external.
12573 * alloc.c, buffer.c, callint.c, callproc.c, casefiddle.c, casetab.c:

12581 Mark functions with DEFUE instead of DEFUN,
12582 if they are used in other modules.
12583 * buffer.c (Fset_buffer_major_mode, Fdelete_overlay): New forward
12584 decls for now-static functions.
12585 * buffer.h (Fdelete_overlay): Remove decl.

12616 2011-04-14 Andreas Schwab <schwab@linux-m68k.org>
12618 * fileio.c (Finsert_file_contents): Fix typo in 2005-05-13
12619 change. (Bug#8496)
12621 2011-04-13 Eli Zaretskii <eliz@gnu.org>
12623 * xdisp.c (handle_invisible_prop): Don't call bidi_paragraph_init
12624 when at ZV. (Bug#8487)
12626 2011-04-12 Andreas Schwab <schwab@linux-m68k.org>
12628 * charset.c (Fclear_charset_maps): Use xfree instead of free.
12629 (Bug#8437)
12630 * keyboard.c (parse_tool_bar_item): Likewise.
12631 * sound.c (sound_cleanup, alsa_close): Likewise.

12634 * xsettings.c (read_and_apply_settings): Likewise.
12636 * alloc.c (overrun_check_malloc, overrun_check_realloc)
12637 (overrun_check_free): Protoize.
12639 2011-04-12 Paul Eggert <eggert@cs.ucla.edu>
12641 * sysdep.c (emacs_read, emacs_write): Check for negative sizes
12642 since callers should never pass a negative size.
12643 Change the signature to match that of plain 'read' and 'write'; see
12644 <http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00397.html>.
12645 * lisp.h: Update prototypes of emacs_write and emacs_read.
12647 2011-04-11 Eli Zaretskii <eliz@gnu.org>
12649 * xdisp.c (redisplay_window): Don't try to determine the character
12650 position of the scroll margin if the window start point w->startp
12651 is outside the buffer's accessible region. (Bug#8468)
12653 2011-04-10 Eli Zaretskii <eliz@gnu.org>
12655 Fix write-region and its subroutines for buffers > 2GB.
12656 * fileio.c (a_write, e_write): Modify declaration of arguments and
12657 local variables to support buffers larger than 2GB.
12658 (Fcopy_file): Use EMACS_INT for return value of emacs_read.
12660 * sysdep.c (emacs_write, emacs_read): Use ssize_t for last
12661 argument, local variables, and return value.
12663 * lisp.h: Update prototypes of emacs_write and emacs_read.
12665 * sound.c (vox_write): Use ssize_t for return value of emacs_write.
12667 2011-04-10 Paul Eggert <eggert@cs.ucla.edu>
12669 * xdisp.c (vmessage): Use memchr, not strnlen, which some hosts lack.
12671 Fix more problems found by GCC 4.6.0's static checks.
12673 * xdisp.c (vmessage): Use a better test for character truncation.
12675 * charset.c (load_charset_map): <, not <=, for optimization,
12676 and to avoid potential problems with integer overflow.
12677 * chartab.c (sub_char_table_set_range, char_table_set_range): Likewise.
12678 * casetab.c (set_identity, shuffle): Likewise.
12679 * editfns.c (Fformat): Likewise.
12680 * syntax.c (skip_chars): Likewise.
12682 * xmenu.c (set_frame_menubar): Allocate smaller local vectors.
12683 This also lets GCC 4.6.0 generate slightly better loop code.
12685 * callint.c (Fcall_interactively): <, not <=, for optimization.
12686 (Fcall_interactively): Count the number of arguments produced,
12687 not the number of arguments given. This is simpler and lets GCC
12688 4.6.0 generate slightly better code.
12690 * ftfont.c: Distingish more carefully between FcChar8 and char.
12691 The previous code passed unsigned char * to a functions like
12692 strlen and xstrcasecmp that expect char *, which does not
12693 conform to the C standard.
12694 (get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
12695 arguments to FcPatternGetString, and explicitly cast FcChar8 * to
12696 char * when the C standard requires it.
12698 * keyboard.c (read_char): Remove unused var.
12700 * eval.c: Port to Windows vsnprintf (Bug#8435).
12701 Include <limits.h>.
12702 (SIZE_MAX): Define if the headers do not.
12703 (verror): Do not give up if vsnprintf returns a negative count.
12704 Instead, grow the buffer. This ports to Windows vsnprintf, which
12705 does not conform to C99. Problem reported by Eli Zaretskii.
12706 Also, simplify the allocation scheme, by avoiding the need for
12707 calling realloc, and removing the ALLOCATED variable.
12709 * eval.c (verror): Initial buffer size is 4000 (not 200) bytes.
12711 Remove invocations of doprnt, as Emacs now uses vsnprintf.
12712 But keep the doprint source code for now, as we might revamp it
12713 and use it again (Bug#8435).
12714 * lisp.h (doprnt): Remove.
12715 * Makefile.in (base_obj): Remove doprnt.o.
12716 * deps.mk (doprnt.o): Remove.
12718 error: Print 32- and 64-bit integers portably (Bug#8435).
12719 Without this change, on typical 64-bit hosts error ("...%d...", N)
12720 was used to print both 32- and 64-bit integers N, which relied on
12721 undefined behavior.
12722 * lisp.h, m/amdx86-64.h, m/ia64.h, m/ibms390x.h (pEd): New macro.
12723 * lisp.h (error, verror): Mark as printf-like functions.
12724 * eval.c (verror): Use vsnprintf, not doprnt, to do the real work.
12725 Report overflow in size calculations when allocating printf buffer.
12726 Do not truncate output string at its first null byte.
12727 * xdisp.c (vmessage): Use vsnprintf, not doprnt, to do the real work.
12728 Truncate the output at a character boundary, since vsnprintf does not
12729 do that.
12730 * charset.c (check_iso_charset_parameter): Convert internal
12731 character to string before calling 'error', since %c now has the
12732 printf meaning.
12733 * coding.c (Fdecode_sjis_char, Fdecode_big5_char): Avoid int
12734 overflow when computing char to be passed to 'error'. Do not
12735 pass Lisp_Object to 'error'; pass the integer instead.
12736 * nsfns.m (Fns_do_applescript): Use int, not long, since it's
12737 formatted with plain %d.
12739 * eval.c (internal_lisp_condition_case): Don't pass spurious arg.
12741 * keyboard.c (access_keymap_keyremap): Print func name, not garbage.
12743 * coding.c (Fdecode_sjis_char): Don't assume CODE fits in int.
12745 * xterm.c (x_catch_errors): Remove duplicate declaration.
12747 * term.c (maybe_fatal): Mark its 3rd arg as a printf format, too.
12749 * xdisp.c, lisp.h (message_nolog): Remove; unused.
12751 2011-04-10 Jim Meyering <meyering@redhat.com>
12753 use ssize_t and size_t for read- and write-like emacs_gnutls_* functions
12754 * gnutls.c (emacs_gnutls_read): Adjust signature to be more read-like:
12755 return ssize_t not "int", and use size_t as the buffer length.
12756 (emacs_gnutls_write): Likewise, and make the buffer pointer "const".
12757 * gnutls.h: Update declarations.
12758 * process.c (read_process_output): Use ssize_t, to match.
12759 (send_process): Likewise.
12761 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
12763 * image.c (Fimagemagick_types): Doc fix, and comment cleanup.
12765 2011-04-09 Chong Yidong <cyd@stupidchicken.com>
12767 * ftfont.c (get_adstyle_property, ftfont_pattern_entity):
12768 Use unsigned char, to match FcChar8 type definition.
12770 * xterm.c (handle_one_xevent):
12771 * xmenu.c (create_and_show_popup_menu):
12772 * xselect.c (x_decline_selection_request)
12773 (x_reply_selection_request): Avoid type-punned deref of X events.
12775 2011-04-09 Eli Zaretskii <eliz@gnu.org>
12777 Fix some uses of `int' instead of EMACS_INT.
12778 * search.c (string_match_1, fast_string_match)
12779 (fast_c_string_match_ignore_case, fast_string_match_ignore_case)
12780 (scan_buffer, find_next_newline_no_quit)
12781 (find_before_next_newline, search_command, Freplace_match)
12782 (Fmatch_data): Make some `int' variables be EMACS_INT.
12784 * xdisp.c (display_count_lines): 3rd argument and return value now
12785 EMACS_INT. All callers changed.
12786 (pint2hrstr): Last argument is now EMACS_INT.
12788 * coding.c (detect_coding_utf_8, detect_coding_emacs_mule)
12789 (detect_coding_iso_2022, detect_coding_sjis, detect_coding_big5)

12793 (decode_coding_ccl, decode_coding_charset)
12794 <consumed_chars, consumed_chars_base>: Declare EMACS_INT.
12795 (decode_coding_iso_2022, decode_coding_emacs_mule)
12796 (decode_coding_sjis, decode_coding_big5, decode_coding_charset)
12797 <char_offset, last_offset>: Declare EMACS_INT.
12798 (encode_coding_utf_8, encode_coding_utf_16)

12806 EMACS_INT.
12807 (decode_eol): Declare pos_byte, pos, and pos_end EMACS_INT.
12808 (produce_chars): from_nchars and to_nchars are now EMACS_INT.

12811 All users changed.
12813 * ccl.c (Fccl_execute_on_string): Declare some variables
12814 EMACS_INT.
12816 2011-04-08 Samuel Thibault <sthibault@debian.org> (tiny change)

12831 instead of using internal_with_output_to_temp_buffer.
12832 (Qhelp_form_show): New var.
12833 (syms_of_keyboard): Use DEFSYM macro.
12835 * print.c (internal_with_output_to_temp_buffer): Function deleted.

12858 * lisp.h (message, message_nolog, fatal): Mark as printf-like.
12860 * xdisp.c (vmessage): Mark as a printf-like function.
12862 * term.c (vfatal, maybe_fatal): Mark as printf-like functions.

12869 to system-supplied API.
12871 * eval.c (Fsignal): Remove excess argument to 'fatal'.
12873 * coding.c (EMIT_ONE_BYTE, EMIT_TWO_BYTES): Use unsigned, not int.
12874 This avoids several warnings with gcc -Wstrict-overflow.
12875 (DECODE_COMPOSITION_RULE): If the rule is invalid, goto invalid_code
12876 directly, rather than having caller test rule sign. This avoids
12877 some unnecessary tests.
12878 * composite.h (COMPOSITION_ENCODE_RULE_VALID): New macro.
12879 (COMPOSITION_ENCODE_RULE): Arguments now must be valid. This
12880 affects only one use, in DECODE_COMPOSITION_RULE, which is changed.
12882 * xfont.c (xfont_text_extents): Remove var that was set but not used.
12883 (xfont_open): Avoid unnecessary tests.
12885 * composite.c (composition_gstring_put_cache): Use unsigned integer.
12887 * composite.h, composite.c (composition_gstring_put_cache):
12888 Use EMACS_INT, not int, for length.
12890 * composite.h (COMPOSITION_DECODE_REFS): New macro,
12891 breaking out part of COMPOSITION_DECODE_RULE.
12892 (COMPOSITION_DECODE_RULE): Use it.
12893 * composite.c (get_composition_id): Remove unused local vars,
12894 by using the new macro.
12896 * textprop.c (set_text_properties_1): Change while to do-while,
12897 since the condition is always true at first.
12899 * intervals.c (graft_intervals_into_buffer): Mark var as used.
12900 (interval_deletion_adjustment): Return unsigned value.
12901 All uses changed.
12903 * process.c (list_processes_1, create_pty, read_process_output):
12904 (exec_sentinel): Remove vars that were set but not used.
12905 (create_pty): Remove unnecessary "volatile"s.
12906 (Fnetwork_interface_info): Avoid possibility of int overflow.
12907 (read_process_output): Do adaptive read buffering even if carryover.
12908 (read_process_output): Simplify nbytes computation if buffered.
12910 * bytecode.c (exec_byte_code): Rename local to avoid shadowing.
12912 * syntax.c (scan_words): Remove var that was set but not used.

12919 * print.c (print_error_message): Avoid int overflow.
12921 * font.c (font_list_entities): Redo for clarity,
12922 so that reader need not know FONT_DPI_INDEX + 1 == FONT_SPACING_INDEX.
12924 * font.c (font_find_for_lface, Ffont_get_glyphs): Remove unused vars.
12925 (font_score): Avoid potential overflow in diff calculation.
12927 * fns.c (substring_both): Remove var that is set but not used.
12928 (sxhash): Redo loop for clarity and to avoid wraparound warning.
12930 * eval.c (funcall_lambda): Rename local to avoid shadowing.
12932 * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int.
12933 Otherwise, GCC 4.6.0 optimizes the loop check away since the check
12934 can always succeed if overflow has undefined behavior.
12936 * search.c (boyer_moore, wordify): Remove vars set but not used.
12937 (wordify): Omit three unnecessary tests.
12939 * indent.c (MULTIBYTE_BYTES_WIDTH): Don't compute wide_column.

12944 * dired.c (file_name_completion): Remove var that is set but not used.
12946 * fileio.c (Finsert_file_contents): Make EOF condition clearer.
12948 * fileio.c (Finsert_file_contents): Avoid signed integer overflow.
12949 (Finsert_file_contents): Remove unnecessary code checking fd.
12951 * minibuf.c (read_minibuf_noninteractive): Use size_t for sizes.
12952 Check for integer overflow on size calculations.
12954 * buffer.c (Fprevious_overlay_change): Remove var that is set
12955 but not used.
12957 * keyboard.c (menu_bar_items, read_char_minibuf_menu_prompt):
12958 Remove vars that are set but not used.
12959 (timer_check_2): Don't assume timer-list and idle-timer-list are lists.
12960 (timer_check_2): Mark vars as initialized.
12962 * gtkutil.c (xg_get_file_with_chooser): Mark var as initialized.
12964 * image.c (lookup_image): Remove var that is set but not used.
12965 (xbm_load): Use parse_p, for gcc -Werror=unused-but-set-variable.
12967 * fontset.c (Finternal_char_font, Ffontset_info): Remove vars
12968 that are set but not used.
12970 * xfns.c (make_invisible_cursor): Don't return garbage
12971 if XCreateBitmapFromData fails (Bug#8410).
12973 * xselect.c (x_get_local_selection, x_handle_property_notify):
12974 Remove vars that are set but not used.
12976 * xfns.c (x_create_tip_frame): Remove var that is set but not used.
12977 (make_invisible_cursor): Initialize a possibly-uninitialized variable.
12979 * xterm.c (x_scroll_bar_to_input_event) [!USE_GTK]:
12980 Remove var that is set but not used.
12981 (scroll_bar_windows_size): Now size_t, not int.
12982 (x_send_scroll_bar_event): Use size_t, not int, for sizes.
12983 Check for overflow.
12985 * xfaces.c (realize_named_face): Remove vars that are set but not used.
12986 (map_tty_color) [!defined MSDOS]: Likewise.
12988 * term.c (tty_write_glyphs): Use size_t; this avoids overflow warning.
12990 * coding.c: Remove vars that are set but not used.
12991 (DECODE_COMPOSITION_RULE): Remove 2nd arg, which is unused.
12992 All callers changed.
12993 (decode_coding_utf_8, decode_coding_utf_16 decode_coding_emacs_mule):
12994 (decode_coding_iso_2022, encode_coding_sjis, encode_coding_big5):
12995 (decode_coding_charset): Remove vars that are set but not used.
12997 * bytecode.c (Fbyte_code) [!defined BYTE_CODE_SAFE]: Remove var
12998 that is set but not used.
13000 * print.c (print_object): Remove var that is set but not used.
13002 Replace 2 copies of readlink code with 1 gnulib version (Bug#8401).
13003 The gnulib version avoids calling malloc in the usual case,
13004 and on 64-bit hosts doesn't have some arbitrary 32-bit limits.
13005 * fileio.c (Ffile_symlink_p): Use emacs_readlink.
13006 * filelock.c (current_lock_owner): Likewise.
13007 * lisp.h (READLINK_BUFSIZE, emacs_readlink): New function.
13008 * sysdep.c: Include allocator.h, careadlinkat.h.
13009 (emacs_no_realloc_allocator): New static constant.
13010 (emacs_readlink): New function.
13011 * deps.mk (sysdep.o): Depend on ../lib/allocator.h and on
13012 ../lib/careadlinkat.h.
13014 2011-04-04 Stefan Monnier <monnier@iro.umontreal.ca>
13016 * keyboard.c (safe_run_hook_funcall): Fix last change (don't stop at the
13017 first non-nil return value).
13019 2011-04-03 Jan Djärv <jan.h.d@swipnet.se>
13021 * nsterm.m (ns_update_auto_hide_menu_bar): Define MAC_OS_X_VERSION_10_6
13022 if not defined (Bug#8403).
13024 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
13026 * xdisp.c (display_count_lines): Remove parameter `start',
13027 unused since revno:20537 (1998-01-01). All callers changed.
13028 (get_char_face_and_encoding): Remove parameter `multibyte_p',
13029 unused since revno:87605 (2008-05-14). All callers changed.
13030 (fill_stretch_glyph_string): Remove parameters `row' and `area',
13031 unused at least since Kim's GUI unification at revno:50135 (2003-03-16)
13032 and thereabouts. All callers changed.
13033 (get_per_char_metric): Remove parameter `f', unused since
13034 revno:87605 (2008-05-14). All callers changed.
13036 2011-04-02 Jim Meyering <meyering@redhat.com>
13038 do not dereference NULL upon failed strdup
13039 * nsfont.m (ns_descriptor_to_entity): Use xstrdup, not strdup.
13040 (ns_get_family): Likewise.
13042 2011-04-02 Juanma Barranquero <lekktu@gmail.com>
13044 * eval.c (unwind_to_catch) [DEBUG_GCPRO]: Remove redundant assignment.
13046 2011-04-02 Jan Djärv <jan.h.d@swipnet.se>
13048 * nsterm.m (ns_update_auto_hide_menu_bar): Only for OSX 10.6 or
13049 later (Bug#8403).
13051 2011-04-01 Stefan Monnier <monnier@iro.umontreal.ca>
13053 Add lexical binding.
13055 * window.c (Ftemp_output_buffer_show): New fun.
13056 (Fsave_window_excursion):
13057 * print.c (Fwith_output_to_temp_buffer): Move to subr.el.
13059 * lread.c (lisp_file_lexically_bound_p): New function.
13060 (Fload): Bind Qlexical_binding.
13061 (readevalloop): Remove `evalfun' arg.
13062 Bind Qinternal_interpreter_environment.
13063 (Feval_buffer): Bind Qlexical_binding.
13064 (defvar_int, defvar_bool, defvar_lisp_nopro, defvar_kboard):
13065 Mark as dynamic.
13066 (syms_of_lread): Declare `lexical-binding'.
13068 * lisp.h (struct Lisp_Symbol): New field `declared_special'.
13070 * keyboard.c (eval_dyn): New fun.
13071 (menu_item_eval_property): Use it.
13073 * image.c (parse_image_spec): Use Ffunctionp.
13075 * fns.c (concat, mapcar1): Accept byte-code-functions.
13077 * eval.c (Fsetq): Handle lexical vars.
13078 (Fdefun, Fdefmacro, Ffunction): Make closures when needed.
13079 (Fdefconst, Fdefvaralias, Fdefvar): Mark as dynamic.
13080 (FletX, Flet): Obey lexical binding.
13081 (Fcommandp): Handle closures.
13082 (Feval): New `lexical' arg.
13083 (eval_sub): New function extracted from Feval. Use it almost
13084 everywhere where Feval was used. Look up vars in lexical env.
13085 Handle closures.
13086 (Ffunctionp): Move from subr.el.
13087 (Ffuncall): Handle closures.
13088 (apply_lambda): Remove `eval_flags'.
13089 (funcall_lambda): Handle closures and new byte-code-functions.
13090 (Fspecial_variable_p): New function.
13091 (syms_of_eval): Initialize the Vinternal_interpreter_environment var,
13092 but without exporting it to Lisp.
13094 * doc.c (Fdocumentation, store_function_docstring):
13095 * data.c (Finteractive_form): Handle closures.
13097 * callint.c (Fcall_interactively): Preserve lexical-binding mode for
13098 interactive spec.
13100 * bytecode.c (Bstack_ref, Bstack_set, Bstack_set2, BdiscardN):
13101 New byte-codes.
13102 (exec_byte_code): New function extracted from Fbyte_code to handle new
13103 calling convention for byte-code-functions. Add new byte-codes.
13105 * buffer.c (defvar_per_buffer): Set new `declared_special' field.
13107 * alloc.c (Fmake_symbol): Init new `declared_special' field.
13109 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
13111 * xdisp.c (redisplay_internal): Fix prototype.
13113 2011-03-31 Eli Zaretskii <eliz@gnu.org>
13115 * xdisp.c (SCROLL_LIMIT): New macro.
13116 (try_scrolling): Use it when setting scroll_limit.
13117 Limit scrolling to 100 screen lines.
13118 (redisplay_window): Even when falling back on "recentering",
13119 position point in the window according to scroll-conservatively,
13120 scroll-margin, and scroll-*-aggressively variables. (Bug#6671)
13122 (try_scrolling): When point is above the window, allow searching
13123 as far as scroll_max, or one screenful, to compute vertical
13124 distance from PT to the scroll margin position. This prevents
13125 try_scrolling from unnecessarily failing when
13126 scroll-conservatively is set to a value slightly larger than the
13127 window height. Clean up the case of PT below the margin at bottom
13128 of window: scroll_max can no longer be INT_MAX. When aggressive
13129 scrolling is in use, don't let point enter the opposite scroll
13130 margin as result of the scroll.
13131 (syms_of_xdisp) <scroll-conservatively>: Document the
13132 threshold of 100 lines for never-recentering scrolling.
13134 2011-03-31 Juanma Barranquero <lekktu@gmail.com>
13136 * dispextern.h (move_it_by_lines):
13137 * xdisp.c (move_it_by_lines): Remove parameter `need_y_p', unused
13138 since revno:34925 (2000-12-29). All callers changed.
13139 (message_log_check_duplicate): Remove parameters `prev_bol' and
13140 `this_bol', unused since revno:20537 (1998-01-01). All callers changed.
13141 (redisplay_internal): Remove parameter `preserve_echo_area',
13142 unused since revno:25013 (1999-07-21). All callers changed.
13144 * indent.c (Fvertical_motion):
13145 * window.c (window_scroll_pixel_based, Frecenter):
13146 Don't pass `need_y_p' to `move_it_by_lines'.
13148 2011-03-30 Stefan Monnier <monnier@iro.umontreal.ca>
13150 * eval.c (struct backtrace): Don't cheat with negative numbers, but do
13151 steal a few bits to be more compact.
13152 (interactive_p, Fbacktrace, Fbacktrace_frame, mark_backtrace):
13153 Remove unneeded casts.
13155 * bytecode.c (Fbyte_code): CAR and CDR can GC.
13157 2011-03-30 Zachary Kanfer <zkanfer@gmail.com> (tiny change)
13159 * keyboard.c (Fexecute_extended_command): Do log the "suggest key
13160 binding" message (bug#7967).
13162 2011-03-30 Paul Eggert <eggert@cs.ucla.edu>
13164 Fix more problems found by GCC 4.6.0's static checks.
13166 * unexelf.c (unexec) [! (defined _SYSTYPE_SYSV || defined __sgi)]:
13167 Remove unused local var.
13169 * editfns.c (Fmessage_box): Remove unused local var.
13171 * xdisp.c (try_window_reusing_current_matrix, x_produce_glyphs):
13172 (note_mode_line_or_margin_highlight, note_mouse_highlight):
13173 Omit unused local vars.
13174 * window.c (shrink_windows): Omit unused local var.
13175 * menu.c (digest_single_submenu): Omit unused local var.
13176 * dispnew.c (update_window) [PERIODIC_PREEMPTION_CHECKING]:
13177 Omit unused local var.
13179 * keyboard.c (parse_modifiers_uncached, parse_modifiers):
13180 Don't assume string length fits in int.
13181 (keyremap_step, read_key_sequence): Use size_t for sizes.
13182 (read_key_sequence): Don't check last_real_key_start redundantly.
13184 * callproc.c (Fcall_process, Fcall_process_region): Use SAFE_ALLOCA
13185 instead of alloca (Bug#8344).
13187 * eval.c (Fbacktrace): Don't assume nargs fits in int.
13188 (Fbacktrace_frame): Don't assume nframes fits in int.
13190 * syntax.c (scan_sexps_forward): Avoid pointer wraparound.
13192 * xterm.c (x_make_frame_visible, same_x_server): Redo to avoid overflow
13193 concerns.
13195 * term.c (produce_glyphless_glyph): Remove unnecessary test.
13197 * cm.c (calccost): Turn while-do into do-while, for clarity.
13199 * keyboard.c (syms_of_keyboard): Use the same style as later
13200 in this function when indexing through an array. This also
13201 works around GCC bug 48267.
13203 * image.c (tiff_load): Fix off-by-one image count (Bug#8336).
13205 * xselect.c (x_check_property_data): Return correct size (Bug#8335).
13207 * chartab.c (sub_char_table_ref_and_range): Redo for slight
13208 efficiency gain, and to bypass a gcc -Wstrict-overflow warning.
13210 * keyboard.c, keyboard.h (num_input_events): Now size_t.
13211 This avoids undefined behavior on integer overflow, and is a bit
13212 more convenient anyway since it is compared to a size_t variable.
13214 Variadic C functions now count arguments with size_t, not int.
13215 This avoids an unnecessary limitation on 64-bit machines, which
13216 caused (substring ...) to crash on large vectors (Bug#8344).
13217 * lisp.h (struct Lisp_Subr.function.aMANY): Now takes size_t, not int.
13218 (DEFUN_ARGS_MANY, internal_condition_case_n, safe_call): Likewise.

13225 (funcall_lambda, mark_backtrace): Likewise.
13226 * fns.c (concat): Likewise.
13227 * frame.c (x_set_frame_parameters): Likewise.
13228 * fns.c (get_key_arg): Now accepts and returns size_t, and returns
13229 0 if not found, not -1. All callers changed.
13231 * alloc.c (garbage_collect): Don't assume stack size fits in int.
13232 (stack_copy_size): Now size_t, not int.
13233 (stack_copy, stack_copy_size): Define only if MAX_SAVE_STACK > 0.
13235 2011-03-28 Juanma Barranquero <lekktu@gmail.com>
13237 * coding.c (encode_designation_at_bol): Remove parameter `charbuf_end',
13238 unused since revno:43563.1.17 (2002-03-01) and revno:84043 (2008-02-1).
13239 All callers changed.
13241 * lisp.h (multibyte_char_to_unibyte):
13242 * character.c (multibyte_char_to_unibyte): Remove parameter `rev_tbl',
13243 unused since revno:43563.1.16 (2002-03-01) and revno:84043 (2008-02-1).
13244 * character.h (CHAR_TO_BYTE8):
13245 * cmds.c (internal_self_insert):
13246 * editfns.c (general_insert_function):
13247 * keymap.c (push_key_description):
13248 * search.c (Freplace_match):
13249 * xdisp.c (message_dolog, set_message_1): All callers changed.
13251 2011-03-28 Stefan Monnier <monnier@iro.umontreal.ca>
13253 * keyboard.c (safe_run_hook_funcall): New function.
13254 (safe_run_hooks_1, safe_run_hooks_error, safe_run_hooks): On error,
13255 don't set the hook to nil, but remove the offending function instead.

13440 Use Frun_hooks.
13441 (command_loop_1): Use Frun_hooks. Call safe_run_hooks

13444 2011-03-23 Paul Eggert <eggert@cs.ucla.edu>
13446 Fix more problems found by GCC 4.5.2's static checks.
13448 * coding.c (encode_coding_raw_text): Avoid unnecessary test
13449 the first time through the loop, since we know p0 < p1 then.
13450 This also avoids a gcc -Wstrict-overflow warning.
13452 * lisp.h (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Avoid 'int' overflow
13453 leading to a memory leak, possible in functions like
13454 load_charset_map_from_file that can allocate an unbounded number
13455 of objects (Bug#8318).
13457 * xmenu.c (set_frame_menubar): Use EMACS_UINT, not int, for indexes
13458 that could (at least in theory) be that large.
13460 * xdisp.c (message_log_check_duplicate): Return unsigned long, not int.
13461 This is less likely to overflow, and avoids undefined behavior if
13462 overflow does occur. All callers changed. Use strtoul to scan
13463 for the unsigned long integer.
13464 (pint2hrstr): Simplify and tune code slightly.
13465 This also avoids a (bogus) GCC warning with gcc -Wstrict-overflow.

13480 * process.c (Fmake_network_process): Use socklen_t, not int,
13481 where POSIX says socklen_t is required in portable programs.
13482 This fixes a porting bug on hosts like 64-bit HP-UX, where
13483 socklen_t is wider than int (Bug#8277).
13484 (Fmake_network_process, server_accept_connection):
13485 (wait_reading_process_output, read_process_output):
13486 Likewise.

13498 Make tparam.h and terminfo.c consistent.
13499 * cm.c (tputs, tgoto, BC, UP): Remove extern decls.
13500 Include tparam.h instead, since it declares them.
13501 * cm.h (PC): Remove extern decl; tparam.h now does this.
13502 * deps.mk (cm.o, terminfo.o): Depend on tparam.h.
13503 * terminfo.c: Include tparam.h, to check interfaces.
13504 (tparm): Make 1st arg a const pointer in decl. Put it at top level.
13505 (tparam): Adjust signature to match interface in tparam.h;
13506 this removes some undefined behavior. Check that outstring and len
13507 are zero, which they always are with Emacs.
13508 * tparam.h (PC, BC, UP): New extern decls.
13510 * xftfont.c (xftfont_shape): Now static, and defined only if needed.
13511 (xftfont_open): Rename locals to avoid shadowing.

13528 (find_automatic_composition, composition_adjust_point): Likewise.
13529 (composition_update_it): Mark var as initialized.

13550 Fix pointer signedness.
13551 (alsa_choose_format): Remove unused local var.
13552 (wav_play): Initialize a variable to 0, to prevent undefined
13553 behavior (Bug#8278).
13555 * region-cache.c (insert_cache_boundary): Redo var to avoid shadowing.
13557 * region-cache.h (pp_cache): New decl, for gcc -Wmissing-prototypes.
13559 * callproc.c (Fcall_process): Use 'volatile' to avoid vfork
13560 clobbering (Bug#8298).
13561 * sysdep.c (sys_subshell): Likewise.
13562 Previously, the sys_subshell 'volatile' was incorrectly IF_LINTted out.
13564 * lisp.h (child_setup): Now NO_RETURN unless DOS_NT.
13565 This should get cleaned up, so that child_setup has the
13566 same signature on all platforms.
13568 * callproc.c (call_process_cleanup): Now static.
13569 (relocate_fd): Rename locals to avoid shadowing.
13571 2011-03-22 Chong Yidong <cyd@stupidchicken.com>
13573 * xterm.c (x_clear_frame): Remove XClearWindow call. This appears
13574 not to be necessary, and produces flickering.
13576 2011-03-20 Glenn Morris <rgm@gnu.org>
13578 * config.in: Remove file.
13580 2011-03-20 Juanma Barranquero <lekktu@gmail.com>

13625 Define only if needed.
13627 * unexelf.c (unexec): Name an expression,
13628 to avoid gcc -Wbad-function-cast warning.
13629 Use a different way to cause a compilation error if anyone uses
13630 n rather than nn, a way that does not involve shadowing.
13631 (ELF_BSS_SECTION_NAME, OLD_PROGRAM_H): Remove; unused.
13633 * deps.mk (unexalpha.o): Remove; unused.

13706 * doc.c (Fdocumentation, Fsnarf_documentation): Move locals to
13707 avoid shadowing.
13709 * lisp.h (eassert): Check that the argument compiles, even if
13710 ENABLE_CHECKING is not defined.
13712 * data.c (Findirect_variable): Name an expression, to avoid
13713 gcc -Wbad-function-cast warning.
13714 (default_value, arithcompare, arith_driver, arith_error): Now static.
13715 (store_symval_forwarding): Rename local to avoid shadowing.

13717 Mark variables as initialized.
13718 (do_blv_forwarding, do_symval_forwarding): Remove; unused.
13720 * alloc.c (check_cons_list): Do not define unless GC_CHECK_CONS_LIST.
13721 (Fmake_vector, Fvector, Fmake_byte_code, Fgarbage_collect):
13722 Rename locals to avoid shadowing.

13724 they're used.
13725 (BLOCK_INPUT_ALLOC, UNBLOCK_INPUT_ALLOC): Define only if
13726 ! defined SYSTEM_MALLOC && ! defined SYNC_INPUT, as they are not
13727 needed otherwise.
13728 (CHECK_ALLOCATED): Define only if GC_CHECK_MARKED_OBJECTS.
13729 (GC_STRING_CHARS): Remove; not used.
13730 (Fmemory_limit): Cast sbrk's returned value to char *.
13732 * lisp.h (check_cons_list): Declare if GC_CHECK_CONS_LIST; this
13733 avoids undefined behavior in theory.
13735 * regex.c (IF_LINT): Add defn, for benefit of ../lib-src.
13737 Use functions, not macros, for up- and down-casing (Bug#8254).
13738 * buffer.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
13739 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Remove. All callers changed
13740 to use the following functions instead of these macros.
13741 (downcase): Adjust to lack of DOWNCASE_TABLE. Return int, not
13742 EMACS_INT, since callers assume the returned value fits in int.
13743 (upcase1): Likewise, for UPCASE_TABLE.
13744 (uppercasep, lowercasep, upcase): New static inline functions.
13745 * editfns.c (Fchar_equal): Remove no-longer-needed workaround for
13746 the race-condition problem in the old DOWNCASE.
13748 * regex.c (CHARSET_LOOKUP_RANGE_TABLE_RAW, POP_FAILURE_REG_OR_COUNT):
13749 Rename locals to avoid shadowing.

13751 (regex_compile, re_search_2, re_match_2_internal):
13752 Remove unused local vars.
13753 (FREE_VAR): Rewrite so as not to use empty "else",
13754 which gcc can warn about.
13755 (regex_compile, re_match_2_internal): Mark locals as initialized.
13756 (RETALLOC_IF): Define only if needed.
13757 (WORDCHAR_P): Likewise. This one is never needed, but is used
13758 only in a comment talking about a compiler bug, so put inside
13759 the #if 0 of that comment.
13760 (CHARSET_LOOKUP_BITMAP, FAIL_STACK_FULL, RESET_FAIL_STACK):
13761 (PUSH_FAILURE_ELT, BUF_PUSH_3, STOP_ADDR_VSTRING):
13762 Remove; unused.
13764 * search.c (boyer_moore): Rename locals to avoid shadowing.

13766 (PREV_CHAR_BOUNDARY): Likewise.
13768 * search.c (simple_search): Remove unused var.
13770 * dired.c (compile_pattern): Move decl from here ...
13771 * lisp.h: ... to here, so that it can be checked.
13772 (struct re_registers): New forward decl.
13774 * character.h (INC_POS, DEC_POS): Rename locals to avoid shadowing.
13776 * indent.c (MULTIBYTE_BYTES_WIDTH): New args bytes, width.
13777 All uses changed.
13778 (MULTIBYTE_BYTES_WIDTH, scan_for_column, compute_motion):
13779 Rename locals to avoid shadowing.
13780 (Fvertical_motion): Mark locals as initialized.
13782 * casefiddle.c (casify_object, casify_region): Now static.
13783 (casify_region): Mark local as initialized.
13785 * cmds.c (internal_self_insert): Rename local to avoid shadowing.
13787 * lisp.h (GCPRO2_VAR, GCPRO3_VAR, GCPRO4_VAR, GCPRO5_VAR, GCPRO6_VAR):
13788 New macros, so that the caller can use some names other than
13789 gcpro1, gcpro2, etc.
13790 (GCPRO2, GCPRO3, GCPRO4, GCPRO5, GCPRO6): Reimplement in terms
13791 of the new macros.
13792 (GCPRO1_VAR, UNGCPRO_VAR): Change the meaning of the second
13793 argument, for consistency with GCPRO2_VAR, etc: it is now the
13794 prefix of the variable, not the variable itself. All uses
13795 changed.
13796 * dired.c (directory_files_internal, file_name_completion):
13797 Rename locals to avoid shadowing.
13799 Fix a race condition diagnosed by gcc -Wsequence-point (Bug#8254).
13800 An expression of the form (DOWNCASE (x) == DOWNCASE (y)), found in
13801 dired.c's scmp function, had undefined behavior.
13802 * lisp.h (DOWNCASE_TABLE, UPCASE_TABLE, DOWNCASE, UPPERCASEP):
13803 (NOCASEP, LOWERCASEP, UPCASE, UPCASE1): Move from here ...
13804 * buffer.h: ... to here, because these macros use current_buffer,
13805 and the new implementation with inline functions needs to have
13806 current_buffer in scope now, rather than later when the macros
13807 are used.
13808 (downcase, upcase1): New static inline functions.
13809 (DOWNCASE, UPCASE1): Reimplement using these functions.
13810 This avoids undefined behavior in expressions like
13811 DOWNCASE (x) == DOWNCASE (y), which previously suffered
13812 from race conditions in accessing the global variables
13813 case_temp1 and case_temp2.
13814 * casetab.c (case_temp1, case_temp2): Remove; no longer needed.
13815 * lisp.h (case_temp1, case_temp2): Remove their decls.
13816 * character.h (ASCII_CHAR_P): Move from here ...
13817 * lisp.h: ... to here, so that the inline functions mentioned
13818 above can use them.
13820 * dired.c (directory_files_internal_unwind): Now static.
13822 * fileio.c (file_name_as_directory, directory_file_name):
13823 (barf_or_query_if_file_exists, auto_save_error, auto_save_1):
13824 Now static.
13825 (file_name_as_directory): Use const pointers when appropriate.
13826 (Fexpand_file_name): Likewise. In particular, newdir might
13827 point at constant storage, so make it a const pointer.
13828 (Fmake_directory_internal, Fread_file_name): Remove unused vars.
13829 (Ffile_selinux_context, Fset_file_selinux_context): Fix pointer
13830 signedness issues.
13831 (Fset_file_times, Finsert_file_contents, auto_save_error):
13832 Rename locals to avoid shadowing.
13834 * minibuf.c (choose_minibuf_frame_1): Now static.
13835 (Ftry_completion, Fall_completions): Rename or remove locals
13836 to avoid shadowing.
13838 * marker.c (bytepos_to_charpos): Remove; unused.
13840 * lisp.h (verify_bytepos, count_markers): New decls,
13841 so that gcc does not warn that these functions aren't declared.
13843 * insdel.c (check_markers, make_gap_larger, make_gap_smaller):
13844 (reset_var_on_error, Fcombine_after_change_execute_1): Now static.
13845 (CHECK_MARKERS): Redo to avoid gcc -Wempty-body diagnostic.
13846 (copy_text): Remove unused local var.
13848 * filelock.c (within_one_second): Now static.
13849 (lock_file_1): Rename local to avoid shadowing.
13851 * buffer.c (fix_overlays_before): Mark locals as initialized.
13852 (fix_start_end_in_overlays): Likewise. This function should be
13853 simplified by using pointers-to-pointers, but that's a different
13854 matter.
13855 (switch_to_buffer_1): Now static.
13856 (Fkill_buffer, record_buffer, Fbury_buffer, Fset_buffer_multibyte):
13857 (report_overlay_modification): Rename locals to avoid shadowing.
13859 * sysdep.c (system_process_attributes): Rename vars to avoid shadowing.
13860 Fix pointer signedness issue.
13861 (sys_subshell): Mark local as volatile if checking for lint,
13862 to suppress a gcc -Wclobbered warning that does not seem to be right.
13863 (MAXPATHLEN): Define only if needed.
13865 * process.c (serial_open, serial_configure): Move decls from here ...
13866 * systty.h: ... to here, so that they can be checked.
13868 * fns.c (get_random, seed_random): Move extern decls from here ...
13869 * lisp.h: ... to here, so that they can be checked.
13871 * sysdep.c (reset_io): Now static.
13872 (wait_for_termination_signal): Remove; unused.
13874 * keymap.c (keymap_parent, keymap_memberp, map_keymap_internal):
13875 (copy_keymap_item, append_key, push_text_char_description):
13876 Now static.
13877 (Fwhere_is_internal): Don't test CONSP (sequences) unnecessarily.
13878 (DENSE_TABLE_SIZE): Remove; unused.
13879 (get_keymap, access_keymap, Fdefine_key, Fwhere_is_internal):
13880 (describe_map_tree):
13881 Rename locals to avoid shadowing.
13883 * keyboard.c: Declare functions static if they are not used elsewhere.
13884 (echo_char, echo_dash, cmd_error, top_level_2):
13885 (poll_for_input, handle_async_input): Now static.

13900 * emacs.c (init_cmdargs): Rename local to avoid shadowing.
13901 (DEFINE_DUMMY_FUNCTION): New macro.
13902 (__do_global_ctors, __do_global_ctors_aux, __do_global_dtors, __main):
13903 Use it.

13905 if GCC considers string literals to be constants.
13907 * lisp.h (fatal_error_signal): Add decl, since it's exported.

13910 (xd_signature, xd_append_arg, xd_initialize):
13911 (Fdbus_call_method, Fdbus_call_method_asynchronously):
13912 (Fdbus_method_return_internal, Fdbus_method_error_internal):

14030 For example, without this patch (encode-time 0 0 0 1 1
14031 1152921504606846976) returns the obviously-bogus value (-948597
14032 62170) on my RHEL 5.5 x86-64 host. With the patch, it correctly
