	The following patches are for when GLYPH_DEBUG && !XASSERT.
	* dispextern.h (trace_redisplay_p, dump_glyph_string):
	* dispnew.c (flush_stdout):
	* xdisp.c (dump_glyph_row, dump_glyph_matrix, dump_glyph):
	Mark as externally visible.
	* dispnew.c (check_window_matrix_pointers): Now static.
	* dispnew.c (window_to_frame_vpos):
	* xfns.c (unwind_create_frame):
	* xterm.c (x_check_font): Remove unused local.
	* scroll.c (CHECK_BOUNDS):
	* xfaces.c (cache_fache): Rename local to avoid shadowing.
	* xfns.c, w32fns.c (image_cache_refcount, dpyinfo_refcount): Now static.
	* xdisp.c (check_window_end): Now a no-op if !XASSERTS.
	(debug_first_unchanged_at_end_vpos, debug_last_unchanged_at_beg_vpos)
	(debug_dvpos, debug_dy, debug_delta, debug_delta_bytes, debug_end_vpos):
	Now static.
	(debug_method_add): Use va_list and vsprintf rather than relying
	on undefined behavior with wrong number of arguments.
	(dump_glyph, dump_glyph_row, Fdump_glyph_matrix):
	Don't assume ptrdiff_t and EMACS_INT are the same width as int.
	In this code, it's OK to assume C99 behavior for ptrdiff_t formats
	since we're not interested in debugging glyphs with old libraries.
	* xfaces.c (cache_face): Move debugging code earlier; this pacifies
	GCC 4.6.0's static checking.

2011-06-22  Paul Eggert  <eggert@cs.ucla.edu>

235 236 237 238 239 240 241 242 243 244 245
	Reformulate so as not to need the command string.
	Invoke gzip -cd rather than gunzip, as it's more portable.
	(lock_info_type, lock_file_1, lock_file):
	Don't assume pid_t and time_t fit in unsigned long.
	(LOCK_PID_MAX): Remove; we now use more-reliable bounds.
	(current_lock_owner): Prefer signed type for sizes.
	Use memcpy, not strncpy, where memcpy is what is really wanted.
	Don't assume (via atoi) that time_t and pid_t fit in int.
	Check for time_t and/or pid_t out of range, e.g., via a network share.
	Don't alloca where an auto var works fine.

246 247 248 249 250 251 252

253 254
	* data.c (Fsubr_name): Rewrite to avoid a strlen call.

255 256
	* coding.c (make_subsidiaries): Don't assume string length fits in int.

	* callproc.c (child_setup): Rewrite to avoid two strlen calls.

259 260 261

	We prefer signed integers, even for size calculations.

262 263 264 265
	* emacs.c: Don't assume string length fits in 'int'.
	(DEFINE_DUMMY_FUNCTION, sort_args): Use ptrdiff_t, not int.
	(main): Don't invoke strlen when not needed.

273 274 275 276
	* lread.c (invalid_syntax): Omit length argument.
	All uses changed.  This doesn't fix a bug, but it simplifies the
	code away from its former Hollerith-constant appearance, and it's
	one less 'int' to worry about when looking at integer-overflow issues.

277
	(string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
278

279 280 281 282
	* lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
	This didn't break anything, but it didn't help either.
	It's confusing to put a bogus integer in a place where the actual
	value does not matter.
283
	(LIST_END_P): Remove unused macro and its bogus comment.
284
	(make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
285

286 287 288
	* lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
	This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
	implementation.
289 290 291
	(struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
	We prefer signed types, and the value cannot exceed the EMACS_INT
	range anyway (because otherwise the length would not be representable).
292 293 294
	(XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,
	not EMACS_UINT and EMACS_INT, when converting pointer to integer.
	This avoids a GCC warning when WIDE_EMACS_INT.
295

296 297 298
	* indent.c (sane_tab_width): New function.
	(current_column, scan_for_column, Findent_to, position_indentation)

299
	(Fcompute_motion): Don't assume hscroll and tab offset fit in int.

402 403 404 405
	* lisp.h: Include <limits.h>, for INT_MAX, LONG_MAX, LLONG_MAX.
	Without this, prin1 mishandles Lisp_Misc_Save_Value printing on
	hosts with pre-C99 libraries, because pD is wrongly defined to "t".

406
	Improve buffer-overflow checking (Bug#8873).
407 408 409 410 411 412 413 414 415
	* fileio.c (Finsert_file_contents):
	* insdel.c (insert_from_buffer_1, replace_range, replace_range_2):
	Remove the old (too-loose) buffer overflow checks.
	They weren't needed, since make_gap checks for buffer overflow.
	* insdel.c (make_gap_larger): Catch buffer overflows that were missed.
	The old code merely checked for Emacs fixnum overflow, and relied
	on undefined (wraparound) behavior.  The new code avoids undefined
	behavior, and also checks for ptrdiff_t and/or size_t overflow.

416
	* editfns.c (Finsert_char): Don't dump core with very negative counts.
417 418
	Tune.  Don't use wider integers than needed.  Don't use alloca.
	Use a bigger 'string' buffer.  Rewrite to avoid 'n > 0' test.
419

420 421
	* insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.

422 423 424 425 426 427

434 435 436
	* ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
	(GET_CCL_RANGE, IN_INT_RANGE): Use it.

437 438 439 440 441
	* fileio.c: Don't assume EMACS_INT fits in off_t.
	(emacs_lseek): New static function.
	(Finsert_file_contents, Fwrite_region): Use it.
	Use SEEK_SET, SEEK_CUR, SEEK_END as appropriate.

442 443
	* fns.c (Fload_average): Don't assume 100 * load average fits in int.

444 445 446 447 448 449 450 451 452
	* fns.c: Don't overflow int when computing a list length.
	* fns.c (QUIT_COUNT_HEURISTIC): New constant.
	(Flength, Fsafe_length): Use EMACS_INT, not int, to avoid unwanted
	truncation on 64-bit hosts.  Check for QUIT every
	QUIT_COUNT_HEURISTIC entries rather than every other entry; that's
	faster and is responsive enough.
	(Flength): Report an error instead of overflowing an integer.
	(Fsafe_length): Return a float if the value is not representable
	as a fixnum.  This shouldn't happen except in contrived situations.
453
	(Fnthcdr, Fsort): Don't assume list length fits in int.
454
	(Fcopy_sequence): Don't assume vector length fits in int.
455

456 457 458 459 460 461 462
	* alloc.c: Check that resized vectors' lengths fit in fixnums.
	(header_size, word_size): New constants.
	(allocate_vectorlike): Don't check size overflow here.
	(allocate_vector): Check it here instead, since this is the only
	caller of allocate_vectorlike that could cause overflow.
	Check that the new vector's length is representable as a fixnum.

463 464 465 466 467 468
	* fns.c (next_almost_prime): Don't return a multiple of 3 or 5.
	The previous code was bogus.  For example, next_almost_prime (32)
	returned 39, which is undesirable as it is a multiple of 3; and
	next_almost_prime (24) returned 25, which is a multiple of 5 so
	why was the code bothering to check for multiples of 7?

469 470
	* bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.

471 472
	* eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.

473 474 475 476
	Variadic C functions now count arguments with ptrdiff_t.
	This partly undoes my 2011-03-30 change, which replaced int with size_t.
	Back then I didn't know that the Emacs coding style prefers signed int.
	Also, in the meantime I found a few more instances where arguments
477 478
	were being counted with int, which may truncate counts on 64-bit
	machines, or EMACS_INT, which may be unnecessarily wide.
479 480 481 482 483 484 485 486 487 488 489 490 491 492 493 494 495
	* lisp.h (struct Lisp_Subr.function.aMANY)
	(DEFUN_ARGS_MANY, internal_condition_case_n, safe_call):
	Arg counts are now ptrdiff_t, not size_t.
	All variadic functions and their callers changed accordingly.
	(struct gcpro.nvars): Now size_t, not size_t.  All uses changed.
	* bytecode.c (exec_byte_code): Check maxdepth for overflow,
	to avoid potential buffer overrun.  Don't assume arg counts fit in 'int'.
	* callint.c (Fcall_interactively): Check arg count for overflow,
	to avoid potential buffer overrun.  Use signed char, not 'int',
	for 'varies' array, so that we needn't bother to check its size
	calculation for overflow.
	* editfns.c (Fformat): Use ptrdiff_t, not EMACS_INT, to count args.
	* eval.c (apply_lambda):
	* fns.c (Fmapconcat): Use XFASTINT, not XINT, to get args length.
	(struct textprop_rec.argnum): Now ptrdiff_t, not int.  All uses changed.
	(mapconcat): Use ptrdiff_t, not int and EMACS_INT, to count args.

496 497
	* callint.c (Fcall_interactively): Don't use index var as event count.

498 499 500
	* vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
	* mem-limits.h (SIZE): Remove; no longer used.

501
	* xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.

	These aren't needed now that we assume ANSI C.

509 510 511 512

531 532 533
	* character.h (CHAR_VALID_P): Remove unused parameter.
	* fontset.c, lisp.h, xdisp.c: All uses changed.

534 535
	* editfns.c (Ftranslate_region_internal): Omit redundant test.

536 537 538 539 540 541
	* fns.c (concat): Minor tuning based on overflow analysis.
	This doesn't fix any bugs.  Use int to hold character, instead
	of constantly refetching from Emacs object.  Use XFASTINT, not
	XINT, for value known to be a character.  Don't bother comparing
	a single byte to 0400, as it's always less.

542
	* floatfns.c (Fexpt):
543 544
	* fileio.c (make_temp_name): Omit unnecessary cast to unsigned.

545 546 547
	* editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
	for characters.

548 549
	* doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.

550 551 552 553 554
	* data.c (Faset): If ARRAY is a string, check that NEWELT is a char.
	Without this fix, on a 64-bit host (aset S 0 4294967386) would
	incorrectly succeed when S was a string, because 4294967386 was
	truncated before it was used.

555 556 557 558
	* chartab.c (Fchar_table_range): Use CHARACTERP to check range.
	Otherwise, an out-of-range integer could cause undefined behavior
	on a 64-bit host.

559 560 561 562 563 564
	* composite.c: Use int, not EMACS_INT, for characters.
	(fill_gstring_body, composition_compute_stop_pos): Use int, not
	EMACS_INT, for values that are known to be in character range.
	This doesn't fix any bugs but is the usual style inside Emacs and
	may generate better code on 32-bit machines.

565 566 567 568 569 570 571 572
	Make sure a 64-bit char is never passed to ENCODE_CHAR.
	This is for reasons similar to the recent CHAR_STRING fix.
	* charset.c (Fencode_char): Check that character arg is actually
	a character.  Pass an int to ENCODE_CHAR.
	* charset.h (ENCODE_CHAR): Verify that the character argument is no
	wider than 'int', as a compile-time check to prevent future regressions
	in this area.

573
	* character.c (char_string): Remove unnecessary casts.
574 575 576 577 578 579 580 581 582 583

	Make sure a 64-bit char is never passed to CHAR_STRING.
	Otherwise, CHAR_STRING would do the wrong thing on a 64-bit platform,
	by silently ignoring the top 32 bits, allowing some values
	that were far too large to be valid characters.
	* character.h: Include <verify.h>.
	(CHAR_STRING, CHAR_STRING_ADVANCE): Verify that the character
	arguments are no wider than unsigned, as a compile-time check
	to prevent future regressions in this area.

594 595 596 597 598
	Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
	These casts should not be needed on 32-bit hosts, either.

	(n_interval_blocks, n_string_blocks, n_float_blocks, n_cons_blocks)
	(n_vectors, n_symbol_blocks, n_marker_blocks): Remove.
	These were 'int' variables that could overflow on 64-bit hosts;

	(STRING_BYTES_MAX): New macro, superseding the old one in lisp.h.
	The definition here is exact; the one in lisp.h was approximate.
	(allocate_string_data): Check for string overflow.  This catches
	some instances we weren't catching before.  Also, it catches
	size_t overflow on (unusual) hosts where SIZE_MAX <= min
	(PTRDIFF_MAX, MOST_POSITIVE_FIXNUM), e.g., when size_t is 32 bits
	and ptrdiff_t and EMACS_INT are both 64 bits.

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

	handle_display_spec instead of single_display_spec_intangible_p.
1271 1272

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

	Malloc failure behavior now depends on size of allocation.
	* alloc.c (buffer_memory_full, memory_full): New arg NBYTES.
	* lisp.h: Change signatures accordingly.
	* alloc.c, buffer.c, editfns.c, menu.c, minibuf.c, xterm.c:
	All callers changed.  (Bug#8762)

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