2011-11-06  Paul Eggert  <eggert@cs.ucla.edu>

	Fix some portability problems with 'inline'.
	* dispextern.h (window_box, window_box_height, window_text_bottom_y)
	(window_box_width, window_box_left, window_box_left_offset)
	(window_box_right, window_box_right_offset): Declare extern.
	Otherwise, these inline functions do not conform to C99 and
	are miscompiled by Microsoft compilers.  Reported by Eli Zaretskii in
	<http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>.
	* intervals.c (adjust_intervals_for_insertion)
	(adjust_intervals_for_deletion): Now extern, because otherwise the
	extern inline functions 'offset_intervals' couldn't refer to it.
	(static_offset_intervals): Remove.
	(offset_intervals): Rewrite using the old contents of
	static_offset_intervals.  The old version didn't conform to C99
	because an extern inline function contained a reference to an
	identifier with static linkage.

	return Qleft_to_right.

	(Fwindow_use_time, Fwindow_total_size, Fwindow_normal_size)
	(Fwindow_new_normal, Fwindow_left_column, Fwindow_top_line)
	(Fwindow_margins, Fwindow_fringes, Fwindow_scroll_bars)
	(Fwindow_vscroll): Doc fix.
	(Fwindow_top_child, Fwindow_left_child): Eliminate a nil default
	argument, since it makes no sense to pass a live window and for
	consistency with window-child.

	Time zone name fixes for non-ASCII locales (Bug#641, Bug#9794)
	* editfns.c: Rewrite current-time-zone so that it invokes
	the equivalent of (format-time-string "%Z") to get the time zone name.
	This fixes a bug when the time zone name contains characters that
	need converting from the system time locale to Emacs internal format.
	This fixes a shortcoming that I introduced in my 1999-10-19 patch:
	that patch fixed format-time-string to do the conversion, but
	I forgot to fix current-time-zone.
	(format_time_string): New function, containing most of
	what Fformat_time_string used to contain.
	(Fformat_time_string): Rewrite in terms of format_time_string.
	This doesn't change this function's behavior.
	(current-time-zone): Rewrite to use format_time_string.
	This fixes the bug reported by Michael Schierl in
	<http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg00334.html>.

	Fix part 3 of bug#9771.
	* bidi.c (bidi_line_init): Initialize next_en_pos to zero, not -1.
	(bidi_resolve_neutral): Don't enter the expensive loop looking for
	non-neutral characters if the current character is a paragraph
	separator (a.k.a. Newline).  This avoids running the same
	expensive loop twice, once when we consume the preceding newline
	and the other time when the line actually needs to be displayed.
	Avoid the loop when we see neutrals on the base embedding level
	following a character whose directionality is the same as the
	paragraph's.  This avoids running the expensive loop when a line
	ends in a long sequence of neutrals, like control characters.
	Add assertion against STRONG_AL type.  Slightly rearrange code
	that determines the type of a neutral given the first non-neutral
	that follows it.
	(bidi_level_of_next_char): Set next_en_pos to zero when

	* xdisp.c (move_it_to): Don't bail out early when reaching
	position beyond to_charpos, if we are scanning backwards.
	(move_it_vertically_backward): When DY == 0, make sure we get to
	the first character in the line after the newline.

	Integer and memory overflow issues (Bug#9196).
1214

1215 1216 1217 1218 1219
	* doc.c (get_doc_string): Rework so that
	get_doc_string_buffer_size is the actual buffer size, rather than
	being 1 less than the actual buffer size; this makes xpalloc more
	convenient.

1220 1221 1222 1223
	* image.c (x_allocate_bitmap_record, cache_image):
	* xselect.c (Fx_register_dnd_atom):
	Simplify previous changes by using xpalloc.

1224 1225 1226
	* buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
	since either will do and ptrdiff_t is convenient with xpalloc.

1227 1228 1229 1230 1231 1232 1233 1234 1235 1236 1237 1238 1239 1240 1241 1242 1243 1244 1245 1246 1247 1248 1249 1250 1251 1252 1253 1254 1255 1256 1257 1258 1259 1260 1261 1262 1263 1264 1265 1266 1267
	* charset.c (charset_table_size)
	(struct charset_sort_data.priority): Now ptrdiff_t.
	(charset_compare): Don't overflow if priorities differ greatly.
	(Fsort_charsets): Don't assume list length fits in int.
	Check for size-calculation overflow when allocating sort data.
	(syms_of_charset): Allocate an initial charset table that is
	just under 64 KiB, to avoid problems with glibc malloc and mmap.

	* cmds.c (internal_self_insert): Check for size-calculation overflow.

	* composite.h (struct composition.glyph_len): Now int, not unsigned.
	The actual value is always <= INT_MAX, and leaving it unsigned made
	overflow checking harder.

	* dispextern.h (struct glyph_matrix.rows_allocated)
	(struct face_cache.size): Now ptrdiff_t, for convenience in use
	with xpalloc.  The values are still always <= INT_MAX.

	* indent.c (compute_motion): Adjust to region_cache_forward sig change.

	* lisp.h (xnmalloc, xnrealloc, xpalloc): New decls.
	(SAFE_NALLOCA): New macro.

	* region-cache.c (struct boundary.pos, find_cache_boundary)
	(move_cache_gap, insert_cache_boundary, delete_cache_boundaries)
	(set_cache_region, invalidate_region_cache)
	(revalidate_region_cache, know_region_cache, region_cache_forward)
	(region_cache_backward, pp_cache):
	Use ptrdiff_t, not EMACS_INT, since either will do.  This is needed
	so that ptrdiff_t * can be passed to xpalloc.
	(struct region_cache): Similarly, for gap_start, gap_len, cache_len,
	beg_unchanged, end_unchanged, buffer_beg, buffer_end members.
	(pp_cache): Don't assume cache_len fits in int.
	* region-cache.h: Adjust extern decls to match.

	* search.c (scan_buffer, Freplace_match): Use ptrdiff_t, not
	EMACS_INT, since either will do, for xpalloc.

	* alloc.c: Include verify.h, and check that int fits in ptrdiff_t.
	(xnmalloc, xnrealloc, xpalloc): New functions.

1268 1269 1270 1271
	* bidi.c (bidi_shelve_header_size): New constant.
	(bidi_cache_ensure_space, bidi_shelve_cache): Use it.
	(bidi_cache_ensure_space): Avoid integer overflow when allocating.

1272
	* bidi.c (bidi_cache_shrink):
1273 1274 1275 1276
	* buffer.c (overlays_at, overlays_in, record_overlay_string)
	(overlay_strings):
	Don't update size of array until after memory allocation succeeds,
	because xmalloc/xrealloc may not return.
1277 1278 1279 1280
	(struct sortstrlist.bytes): Now ptrdiff_t, as EMACS_INT doesn't help
	now that we have proper integer overflow checking.
	(record_overlay_string, overlay_strings): Catch overflows when
	calculating size of overlay_str_buf.
1281

1282 1283 1284 1285 1286
	* callproc.c (Fcall_process): Check for size overflow when
	calculating size of args2.
	(child_setup): Avoid overflow by using size_t rather than ptrdiff_t.
	Normally we prefer signed values, but sticking with ptrdiff_t would
	require adding more-complicated checks.
1287 1288 1289 1290

	* ccl.c (Fccl_execute_on_string): Check for memory overflow.
	Use ptrdiff_t rather than EMACS_INT where ptrdiff_t will do.
	Redo buffer-overflow calculations to avoid integer overflow.
1291
	Add a FIXME comment where memory seems to be over-allocated.

	* character.c (Fstring): Check for size-calculation overflow.

	* coding.c (produce_chars): Redo buffer-overflow calculations to avoid
	unnecessary integer overflow.  Check for size overflow.
	(encode_coding_object): Don't update size until xmalloc succeeds.

	* composite.c (get_composition_id): Check for overflow in glyph
	length calculations.

	Integer and memory overflow fixes for display code.
	* dispextern.h (struct glyph_pool.nglyphs): Now ptrdiff_t, not int.

	(scrolling_window): Check for overflow in size calculations.
	(line_draw_cost, realloc_glyph_pool, add_row_entry):
	Don't assume glyph table len fits in int.

	(row_table_size): Now ptrdiff_t, not int.
	(scrolling_window): Avoid overflow in size calculations.
	Don't update size until allocation succeeds.
	* fns.c (concat): Check for overflow in size calculations.
	(next_almost_prime): Verify NEXT_ALMOST_PRIME_LIMIT.
	* lisp.h (RANGED_INTEGERP, TYPE_RANGED_INTEGERP): New macros.

	(get_doc_string): Check for size calculation overflow.
	Don't update size until allocation succeeds.
	(get_doc_string, Fsubstitute_command_keys): Use ptrdiff_t, not
	EMACS_INT, where ptrdiff_t will do.
	(Fsubstitute_command_keys): Check for string overflow.

	* editfns.c (set_time_zone_rule): Don't assume environment length
	fits in int.
	(message_length): Now ptrdiff_t, not int.
	(Fmessage_box): Don't update size until allocation succeeds.
	Don't assume message length fits in int.
	(Fformat): Use ptrdiff_t, not EMACS_INT, where ptrdiff_t will do.

1331 1332 1333 1334
	* emacs.c (main): Do not reallocate argv, since there is a null at
	the end that can be overwritten, and this way there's no need to
	worry about size-calculation overflow.
	(sort_args): Check for size-calculation overflow.
1335 1336 1337 1338 1339 1340 1341 1342 1343 1344 1345 1346 1347 1348 1349 1350 1351 1352 1353 1354 1355 1356 1357 1358 1359 1360 1361 1362 1363 1364 1365 1366 1367 1368 1369 1370 1371 1372 1373

	* eval.c (init_eval_once, grow_specpdl): Don't update size until
	alloc succeeds.
	(call_debugger, grow_specpdl): Redo calculations to avoid overflow.

	* frame.c (set_menu_bar_lines, x_set_frame_parameters)
	(x_set_scroll_bar_width, x_figure_window_size):
	Check for integer overflow.
	(x_set_alpha): Do not assume XINT fits in int.

	* frame.h (struct frame): Use int, not EMACS_INT, where int works.
	This is for the members text_lines, text_cols, total_lines, total_cols,
	where the system imposes an 'int' limit.

	* fringe.c (Fdefine_fringe_bitmap):
	Don't update size until alloc works.

	* ftfont.c (ftfont_get_open_type_spec, setup_otf_gstring)
	(ftfont_shape_by_flt): Check for integer overflow in size calculations.

	* gtkutil.c (get_utf8_string, xg_store_widget_in_map):
	Check for size-calculation overflow.
	(get_utf8_string): Use ptrdiff_t, not size_t, where either will
	do, as we prefer signed integers.

	(xg_store_widget_in_map, xg_remove_widget_from_map)
	(xg_get_widget_from_map, xg_get_scroll_id_for_window)

	overflow.
1378
