3 4 5 6 7
	* buffer.c: Integer signedness fixes.
	(alloc_buffer_text, enlarge_buffer_text):
	Use ptrdiff_t rather than size_t when either will do, as we prefer
	signed integers.

8 9 10 11 12 13 14 15 16 17 18
	* bidi.c: Integer signedness and overflow fixes.
	(bidi_cache_idx, bidi_cache_last_idx, bidi_cache_fetch_state)
	(bidi_cache_search, bidi_cache_find_level_change)
	(bidi_cache_iterator_state, bidi_cache_find, bidi_find_other_level_edge)
	(bidi_dump_cached_states):
	Don't arbitrarily limit cache indexes to int; use ptrdiff_t instead.
	(bidi_cache_size): Use ptrdiff_t rather than size_t, as we prefer
	signed integers.
	(elsz): Make it a (signed) constant.
	(bidi_cache_iterator_state): Check for size-calculation overflow.

19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42
	* alloc.c: Integer signedness and overflow fixes.
	Do not impose an arbitrary 32-bit limit on malloc sizes when debugging.
	(__malloc_size_t): Default to size_t, not to int.
	(pure_size, pure_bytes_used_before_overflow, stack_copy_size)
	(Fgarbage_collect, mark_object_loop_halt, mark_object):
	Prefer ptrdiff_t to size_t when either would do, as we prefer
	signed integers.
	(XMALLOC_OVERRUN_CHECK_OVERHEAD): New macro.
	(xmalloc_overrun_check_header, xmalloc_overrun_check_trailer):
	Now const.  Initialize with values that are in range even if char
	is signed.
	(XMALLOC_PUT_SIZE, XMALLOC_GET_SIZE): Remove, replacing with ...
	(xmalloc_put_size, xmalloc_get_size): New functions.  All uses changed.
	These functions do the right thing with sizes > 2**32.
	(check_depth): Now ptrdiff_t, not int.
	(overrun_check_malloc, overrun_check_realloc, overrun_check_free):
	Adjust to new way of storing sizes.  Check for size overflow bugs
	in rest of code.
	(STRING_BYTES_MAX): Adjust to new overheads.  The old code was
	slightly wrong anyway, as it missed one instance of
	XMALLOC_OVERRUN_CHECK_OVERHEAD.
	(refill_memory_reserve): Omit needless cast to size_t.
	(mark_object_loop_halt): Mark as externally visible.

43 44 45 46 47 48 49
	* xselect.c: Integer signedness and overflow fixes.
	(Fx_register_dnd_atom, x_handle_dnd_message):
	Use ptrdiff_t, not size_t, since we prefer signed.
	(Fx_register_dnd_atom): Check for ptrdiff_t (and size_t) overflow.
	* xterm.h (struct x_display_info): Use ptrdiff_t, not size_t, for
	x_dnd_atoms_size and x_dnd_atoms_length.

50 51 52 53 54 55 56 57 58 59 60
	* doprnt.c: Prefer signed to unsigned when either works.
	* eval.c (verror):
	* doprnt.c (doprnt):
	* lisp.h (doprnt):
	* xdisp.c (vmessage):
	Use ptrdiff_t, not size_t, when using or implementing doprnt,
	since the sizes cannot exceed ptrdiff_t bounds anyway, and we
	prefer signed arithmetic to avoid comparison confusion.
	* doprnt.c (doprnt): Avoid a "+ 1" that can't overflow,
	but is a bit tricky.

61 62 63 64 65 66 67 68 69 70 71 72
	Assume freestanding C89 headers, string.h, stdlib.h.
	* data.c, doprnt.c, floatfns.c, print.c:
	Include float.h unconditionally.
	* gmalloc.c: Assume C89-at-least behavior for preprocessor,
	limits.h, stddef.h, string.h.  Use memset instead of 'flood'.
	* regex.c: Likewise for stddef.h, string.h.
	(ISASCII): Remove; can assume it returns 1 now.  All uses removed.
	* s/aix4-2.h (HAVE_STRING_H): Remove obsolete undef.
	* s/ms-w32.h (HAVE_LIMITS_H, HAVE_STRING_H, HAVE_STDLIB_H)
	(STDC_HEADERS): Remove obsolete defines.
	* sysdep.c: Include limits.h unconditionally.

	Assume support for memcmp, memcpy, memmove, memset.
	* lisp.h, sysdep.c (memcmp, memcpy, memmove, memset):
	* regex.c (memcmp, memcpy):
	Remove; we assume C89 now.

	* gmalloc.c (memcpy, memset, memmove): Remove; we assume C89 now.
	(__malloc_safe_bcopy): Remove; no longer needed.

83 84 85 86
	* lisp.h (struct vectorlike_header, struct Lisp_Subr):  Signed sizes.
	Use EMACS_INT, not EMACS_UINT, for sizes.  The code works equally
	well either way, and we prefer signed to unsigned.

87 88 89
2011-07-06  Paul Eggert  <eggert@cs.ucla.edu>

	Remove unportable assumption about struct layout (Bug#8884).
90 91 92
	* alloc.c (mark_buffer):
	* buffer.c (reset_buffer_local_variables, Fbuffer_local_variables)
	(clone_per_buffer_values): Don't assume that
93 94 95 96 97 98
	sizeof (struct buffer) is a multiple of sizeof (Lisp_Object).
	This isn't true in general, and it's particularly not true
	if Emacs is configured with --with-wide-int.
	* buffer.h (FIRST_FIELD_PER_BUFFER, LAST_FIELD_PER_BUFFER):
	New macros, used in the buffer.c change.

	(struct xsettings): Move font inside HAVE_XFT.
	(GSETTINGS_TOOL_BAR_STYLE, GSETTINGS_FONT_NAME): New defines.
	(GSETTINGS_MONO_FONT): Renamed from SYSTEM_MONO_FONT.
	Move inside HAVE_XFT.

	also.
	(GCONF_TOOL_BAR_STYLE, GCONF_FONT_NAME): New defines.
	(GCONF_MONO_FONT): Renamed from SYSTEM_MONO_FONT. Move inside HAVE_XFT.
	(something_changed_gconfCB): Renamed from something_changedCB.

	(read_and_apply_settings): Add comment.  Call map_tool_bar_style and
	store_tool_bar_style_changed.  Move check for font inside HAVE_XFT and
	call store_font_name_changed.
	(xft_settings_event): Add comment.
	(init_gsettings): Add comment.  Get values for GSETTINGS_TOOL_BAR_STYLE
	and GSETTINGS_FONT_NAME.  Move check for fonts within HAVE_XFT.
	(init_gconf): Add comment.  Get values for GCONF_TOOL_BAR_STYLE
	and GCONF_FONT_NAME.  Move check for fonts within HAVE_XFT.

2011-07-05  Paul Eggert  <eggert@cs.ucla.edu>

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

	* textprop.c (text_property_stickiness):
	Obey Vtext_property_default_nonsticky.
	(syms_of_textprop): Add `display' to Vtext_property_default_nonsticky.
	* w32fns.c (syms_of_w32fns):
	* xfns.c (syms_of_xfns): Don't Add `display' since it's there by default.

2011-07-04  Paul Eggert  <eggert@cs.ucla.edu>

	* fileio.c (barf_or_query_if_file_exists): Use S_ISDIR.
	This is more efficient than Ffile_directory_p and avoids a minor race.

156 157
2011-07-04  Lars Magne Ingebrigtsen  <larsi@gnus.org>

158 159 160

	is a directory before asking whether to use the file name
	(bug#7564).
164 165
	(barf_or_query_if_file_exists): Make the "File is a directory"
	error be more correct.
166

167 168 169 170
	* fns.c (Frequire): Remove the mention of the .gz files, since
	that's installation-specific, but keep the mention of
	`get-load-suffixes'.

	* gnutls.c (Fgnutls_boot): Don't mention :verify-error.
	(syms_of_gnutls): Remove duplicate DEFSYM for
	Qgnutls_bootprop_verify_hostname_error, an error for
	Qgnutls_bootprop_verify_error (which is no longer used).

183 184 185 186
	* eval.c (find_handler_clause): Remove parameters `sig' and `data',
	unused since 2011-01-26T20:02:07Z!monnier@iro.umontreal.ca.  All callers changed.
	Also (re)move comments that are misplaced or no longer relevant.

2011-07-01  Paul Eggert  <eggert@cs.ucla.edu>

	* eval.c (struct backtrace): Simplify and port the data structure.
	Do not assume that "int nargs : BITS_PER_INT - 2;" produces a
	signed bit field, as this assumption is not portable and it makes
	Emacs crash when compiled with Sun C 5.8 on sparc.  Do not use
	"char debug_on_exit : 1" as this is not portable either; instead,
	use the portable "unsigned int debug_on_exit : 1".  Remove unused
	member evalargs.  Remove obsolete comments about cc bombing out.

	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.

	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.

	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.

664 665 666 667
	* lisp.h (DEFUN): Remove bogus use of sizeof (struct Lisp_Subr).
	This didn't break anything, but it didn't help either.

674 675 676
	(struct Lisp_Bool_Vector.size): EMACS_INT, not EMACS_UINT.
	We prefer signed types, and the value cannot exceed the EMACS_INT

677 678 679
	(XSET) [USE_LISP_UNION_TYPE]: Use uintptr_t and intptr_t,

	* 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.

801
	* editfns.c (Finsert_char): Don't dump core with very negative counts.
802 803
	Tune.  Don't use wider integers than needed.  Don't use alloca.

819 820 821
	* ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
	(GET_CCL_RANGE, IN_INT_RANGE): Use it.

822 823 824 825 826
	* 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.

827 828
	* fns.c (Fload_average): Don't assume 100 * load average fits in int.

829 830 831 832 833 834 835 836 837
	* 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.
838
	(Fnthcdr, Fsort): Don't assume list length fits in int.
839
	(Fcopy_sequence): Don't assume vector length fits in int.
840

841 842 843 844 845 846 847
	* 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.

848 849 850 851 852 853
	* 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?

854 855
	* bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.

856 857
	* eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.

858 859 860 861
	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
862 863
	were being counted with int, which may truncate counts on 64-bit
	machines, or EMACS_INT, which may be unnecessarily wide.
864 865 866 867 868 869 870 871 872 873 874 875 876 877 878 879 880
	* 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.

881 882
	* callint.c (Fcall_interactively): Don't use index var as event count.

883 884 885

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

921 922 923 924 925 926
	* 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.

927

928 929
	* fileio.c (make_temp_name): Omit unnecessary cast to unsigned.

930 931 932
	* editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
	for characters.

933 934
	* doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.

935 936 937 938 939
	* 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.

940 941 942 943
	* 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.

944 945 946 947 948 949
	* 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.

950 951 952 953 954 955 956 957
	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.

958
	* character.c (char_string): Remove unnecessary casts.
959 960 961 962 963 964 965 966 967 968

	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,

	* character.h: Include <verify.h>.
