	Avoid some portability problems by eschewing 'extern inline' functions.
	The trivial performance wins aren't worth the portability hassles; see
	<http://lists.gnu.org/archive/html/emacs-devel/2011-11/msg00084.html>
	et seq.

	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)

	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.

	iterator's bidi_p flag if Vpurify_flag is non-nil.  (Bug#9963)
	(Fcurrent_bidi_paragraph_direction): If Vpurify_flag is non-nil,
	return Qleft_to_right.

	(Fset_window_splits, Fwindow_nest, Fset_window_nest)
	(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.

	(bidi_resolve_explicit_1): When next_en_pos is valid for the
	current character, check also for next_en_type being WEAK_EN.
	(bidi_resolve_weak): Don't enter the expensive loop if the current
	position is before next_en_pos.  Record the bidi type of the first
	non-ET, non-BN character we find, in addition to its position.
	(bidi_level_of_next_char): Invalidate next_en_type when
	next_en_pos is over-stepped.

2011-10-20  Paul Eggert  <eggert@cs.ucla.edu>

	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>.
	Jason Rumney's 2007-06-07 change worked around this bug, but
	didn't fix it.
	* systime.h (tzname, timezone): Remove no-longer-used declarations.

2011-10-18  Eli Zaretskii  <eliz@gnu.org>

	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
	invalidating its info.

486 487 488

	* alloc.c (GC_LISP_OBJECT_ALIGNMENT): Use offsetof, not __alignof__
	or sizeof.  __alignof__ gives the wrong answer on Fedora x86-64
	with GCC 4.6.1 when configured with CC='gcc -m32' --with-wide-int;
	this makes Emacs dump core during garbage collection on rare
	occasions.  sizeof is obviously inferior to offsetof here, so
	stick with offsetof.
	(GC_POINTER_ALIGNMENT): New macro.
	(mark_memory): Omit 3rd (offset) arg; caller changed.

	The previous code assumed that file offsets (off_t values) fit in
	EMACS_INT variables, which is not true on typical 32-bit hosts.
	The code messed up by falsely reporting buffer overflow in cases
	such as (insert-file-contents "big" nil 1 2) into an empty buffer
	when "big" contains more than 2**29 bytes, even though this
	inserts just one byte and does not overflow the buffer.
	(Finsert_file_contents): Store file offsets as off_t
	values, not as EMACS_INT values.  Check for overflow when
	converting between EMACS_INT and off_t.  When checking for
	buffer overflow or for overlap, take the offsets into account.
	Don't use EMACS_INT for small values where int suffices.
	When checking for overlap, fix a typo: ZV was used where
	ZV_BYTE was intended.
	(Fwrite_region): Don't assume off_t fits into 'long'.

	* indent.c (position_indentation): Now takes ptrdiff_t, not int.
1188 1189 1190 1191
	(Fvertical_motion): Don't wrap around LINES values that don't fit
	in 'int'.  Instead, treat them as extreme values.  This is good
	enough for windows, which can't have more than INT_MAX lines anyway.

	* Require libxml/parser.h to avoid compilation warning.

1196 1197 1198 1199 1200
	* emacs.c (shut_down_emacs): Call xmlCleanupParser on shutdown.

	* xml.c (parse_region): Don't call xmlCleanupParser after parsing,
	since this reportedly can destroy thread storage.

1210 1211 1212 1213 1214 1215 1216
	* xdisp.c (produce_stretch_glyph): No longer static, compiled also
	when HAVE_WINDOW_SYSTEM is not defined.  Support both GUI and TTY
	frames.  Call tty_append_glyph in the TTY case.  (Bug#9402)

	* term.c (tty_append_glyph): New function.
	(produce_stretch_glyph): Static function and its prototype deleted.

1217 1218

	* image.c (parse_image_spec): Check for nonnegative, not for positive,
	when checking :margin (Bug#9390).
	(IMAGE_NON_NEGATIVE_INTEGER_VALUE_OR_PAIR):
1225
	Rename from IMAGE_POSITIVE_INTEGER_VALUE_OR_PAIR,
1226 1227
	so that the name doesn't mislead.  All uses changed.

	* ccl.c: Improve and simplify overflow checking (Bug#9196).
	(ccl_driver): Do not generate an out-of-range pointer.
	(Fccl_execute_on_string): Remove unnecessary check for
	integer overflow, noted by Stefan Monnier in
	<http://lists.gnu.org/archive/html/emacs-devel/2011-08/msg00979.html>.
	Remove a FIXME that didn't need fixing.

	Integer and memory overflow issues (Bug#9196).
1257

1258 1259 1260 1261 1262
	* 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.

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

1267 1268 1269
	* buffer.c (overlay_str_len): Now ptrdiff_t, not EMACS_INT,
	since either will do and ptrdiff_t is convenient with xpalloc.

	* 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.

	(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.

1311 1312 1313 1314
	* 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.

1315
	* bidi.c (bidi_cache_shrink):
1316 1317 1318 1319
	* 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.
1320 1321 1322 1323
	(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.
1324

1325 1326 1327 1328 1329
	* 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.
1330 1331 1332 1333

	* 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.
1334
	Add a FIXME comment where memory seems to be over-allocated.

	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.
	* dispnew.c (adjust_glyph_matrix, realloc_glyph_pool)
	(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.
	(struct row_entry.bucket, row_entry_pool_size, row_entry_idx)
	(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.
	(NEXT_ALMOST_PRIME_LIMIT): New constant.

	(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.

1374 1375 1376 1377
	* 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.
1378 1379 1380 1381 1382 1383 1384 1385 1386 1387 1388 1389 1390 1391 1392 1393 1394 1395 1396 1397 1398 1399 1400 1401 1402 1403 1404 1405 1406 1407 1408 1409 1410 1411 1412 1413 1414 1415 1416

	* 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.
