3 4 5 6 7
	* xdisp.c (message_log_check_duplicate): Return intmax_t,

	Detect integer overflow in repeat count.
	(message_dolog): Don't assume print length fits in 39 bytes.

8 9 10 11

28
	(get_boot_time): Don't assume gzip command string fits in 100 bytes.
29 30 31 32 33 34 35 36 37 38 39
	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.

40 41 42 43 44 45 46
	* fileio.c: Fix some integer overflow issues.
	(file_name_as_directory, Fexpand_file_name, Fsubstitute_in_file_name):
	Don't assume string length fits in int.
	(directory_file_name): Don't assume string length fits in long.
	(make_temp_name): Don't assume pid fits in int, or that its print
	length is less than 20.

47 48
	* data.c (Fsubr_name): Rewrite to avoid a strlen call.

49 50
	* coding.c (make_subsidiaries): Don't assume string length fits in int.

51 52
	* callproc.c (child_setup): Rewrite to avoid two strlen calls.

53 54 55
	* process.c (Fformat_network_address): Use EMACS_INT, not EMACS_UINT.
	We prefer signed integers, even for size calculations.

56 57 58 59
	* 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.

60 61 62
	* dbusbind.c (XD_ERROR): Don't arbitrarily truncate string.
	(XD_DEBUG_MESSAGE): Don't waste a byte.

63 64
	* callproc.c (getenv_internal_1, getenv_internal)
	(Fgetenv_internal):
65 66
	* buffer.c (init_buffer): Don't assume string length fits in 'int'.

67 68 69 70
	* 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.

Paul Eggert committed
71
	(string_to_number): Simplify 2011-04-26 change by invoking xsignal1.
72

73 74 75 76
	* 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.
77
	(LIST_END_P): Remove unused macro and its bogus comment.
78
	(make_fixnum_or_float): Remove unnecessary cast to EMACS_INT.
79

80 81 82
	* lisp.h (union Lisp_Object.i): EMACS_INT, not EMACS_UINT.
	This is for consistency with the ordinary, non-USE_LISP_UNION_TYPE,
	implementation.
83 84 85
	(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).
86 87 88
	(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.
89

90 91 92
	* indent.c (sane_tab_width): New function.
	(current_column, scan_for_column, Findent_to, position_indentation)
	(compute_motion): Use it.  This is just for clarity.
93
	(Fcompute_motion): Don't assume hscroll and tab offset fit in int.

97 98 99 100
	* lisp.h (lint_assume): New macro.
	* composite.c (composition_gstring_put_cache):
	* ftfont.c (ftfont_shape_by_flt): Use it to pacify GCC 4.6.0.

101 102
	* editfns.c, insdel.c:
	Omit unnecessary forward decls, to simplify future changes.
103

104 105
	* ftfont.c (ftfont_shape_by_flt): Use signed integers for lengths.

106 107
	* font.c (Ffont_shape_gstring): Don't assume glyph len fits in 'int'.

108
	* fns.c (Ffillarray): Don't assume bool vector size fits in 'int'.
109
	Use much-faster test for byte-length change.
110
	Don't assume string byte-length fits in 'int'.
111
	Check that character arg fits in 'int'.
112
	(mapcar1): Declare byte as byte, for clarity.
113

114 115
	* alloc.c (Fmake_bool_vector): Avoid unnecessary multiplication.

116 117 118
	* fns.c (concat): Catch string overflow earlier.
	Do not rely on integer wraparound.

119 120
	* dispextern.h (struct it.overlay_strings_charpos)
	(struct it.selective): Now EMACS_INT, not int.
121 122 123 124 125
	* xdisp.c (forward_to_next_line_start)
	(back_to_previous_visible_line_start)
	(reseat_at_next_visible_line_start, next_element_from_buffer):
	Don't arbitrarily truncate the value of 'selective' to int.

126 127
	* xdisp.c (init_iterator): Use XINT, not XFASTINT; it might be < 0.

128 129 130
	* composite.c: Don't truncate sizes to 'int'.
	(composition_gstring_p, composition_reseat_it)
	(composition_adjust_point): Use EMACS_INT, not int.
131 132
	(get_composition_id, composition_gstring_put_cache): Use EMACS_INT,
	not EMACS_UINT, for indexes.
133

134 135

136 137
	* buffer.c: Include <verify.h>.
	(struct sortvec.priority, struct sortstr.priority):
138
	Now EMACS_INT, not int.
139
	(compare_overlays, cmp_for_strings): Avoid subtraction overflow.
140 141 142 143
	(struct sortstr.size, record_overlay_string)
	(struct sortstrlist.size, struct sortlist.used):
	Don't truncate size to int.

2011-06-18  Chong Yidong  <cyd@stupidchicken.com>

	* dispnew.c (add_window_display_history): Use BVAR.

	* xdisp.c (debug_method_add): Use BVAR.
	(check_window_end, dump_glyph_matrix, dump_glyph)
	(dump_glyph_row, dump_glyph_string): Convert arglist to ANSI C.

	* xfaces.c (check_lface_attrs, check_lface, dump_realized_face):
	Likewise.

	* xfns.c (Fx_create_frame, x_create_tip_frame): Delay image cache
	check till after the cache is created in init_frame_faces.

165 166 167 168
2011-06-17  Stefan Monnier  <monnier@iro.umontreal.ca>

	* fns.c (Fsafe_length): Yet another int/Lisp_Object mixup.

169 170
2011-06-16  Paul Eggert  <eggert@cs.ucla.edu>

171 172 173 174
	* 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".

175
	Improve buffer-overflow checking (Bug#8873).
176 177 178 179 180 181 182 183 184
	* 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.

185
	* editfns.c (Finsert_char): Don't dump core with very negative counts.
186 187
	Tune.  Don't use wider integers than needed.  Don't use alloca.
	Use a bigger 'string' buffer.  Rewrite to avoid 'n > 0' test.
188

189 190
	* insdel.c (replace_range): Fix buf overflow when insbytes < outgoing.

191 192 193 194 195 196
	* insdel.c, lisp.h (buffer_overflow): New function.
	(insert_from_buffer_1, replace_range, replace_range_2):
	* insdel.c (make_gap_larger):
	* editfns.c (Finsert_char):
	* fileio.c (Finsert_file_contents): Use it, to normalize wording.

197 198
	* buffer.h (BUF_BYTES_MAX): Cast to ptrdiff_t so that it's signed.

199 200
2011-06-15  Paul Eggert  <eggert@cs.ucla.edu>

201
	Integer overflow and signedness fixes (Bug#8873).

Paul Eggert committed
202

203 204 205
	* ccl.c (ASCENDING_ORDER): New macro, to work around GCC bug 43772.
	(GET_CCL_RANGE, IN_INT_RANGE): Use it.

206 207 208 209 210
	* 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.

211 212
	* fns.c (Fload_average): Don't assume 100 * load average fits in int.

213 214 215 216 217 218 219 220 221
	* 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.
222
	(Fnthcdr, Fsort): Don't assume list length fits in int.
223
	(Fcopy_sequence): Don't assume vector length fits in int.
224

225 226 227 228 229 230 231
	* 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.

232 233 234 235 236 237
	* 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?

238 239
	* bytecode.c (exec_byte_code): Use ptrdiff_t, not int, for vector length.

240 241
	* eval.c, doprnt.c (SIZE_MAX): Remove; inttypes.h defines this now.

242 243 244 245
	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
246 247
	were being counted with int, which may truncate counts on 64-bit
	machines, or EMACS_INT, which may be unnecessarily wide.
248 249 250 251 252 253 254 255 256 257 258 259 260 261 262 263 264
	* 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.

265 266
	* callint.c (Fcall_interactively): Don't use index var as event count.

267 268 269
	* vm-limit.c (check_memory_limits): Fix incorrect extern function decls.
	* mem-limits.h (SIZE): Remove; no longer used.

270
	* xterm.c (x_alloc_nearest_color_1): Prefer int to long when int works.

	Remove unnecessary casts.
	* xterm.c (x_term_init):
	* xfns.c (x_set_border_pixel):
	* widget.c (create_frame_gcs): Remove casts to unsigned long etc.
	These aren't needed now that we assume ANSI C.

278 279 280 281
	* sound.c (Fplay_sound_internal): Remove cast to unsigned long.
	It's more likely to cause problems (due to unsigned overflow)
	than to cure them.

282 283
	* dired.c (Ffile_attributes): Don't use 32-bit hack on 64-bit hosts.

284 285
	* unexelf.c (unexec): Don't assume BSS addr fits in unsigned.

286 287
	* xterm.c (handle_one_xevent): Omit unnecessary casts to unsigned.

288 289
	* keyboard.c (modify_event_symbol): Don't limit alist len to UINT_MAX.

290 291
	* lisp.h (CHAR_TABLE_SET): Omit now-redundant test.

292 293
	* lread.c (Fload): Don't compare a possibly-garbage time_t value.

294 295 296
	GLYPH_CODE_FACE returns EMACS_INT, not int.
	* dispextern.h (merge_faces):
	* xfaces.c (merge_faces):

297 298
	* xdisp.c (get_next_display_element, next_element_from_display_vector):
	Don't assume EMACS_INT fits in int.
299

300 301 302
	* character.h (CHAR_VALID_P): Remove unused parameter.
	* fontset.c, lisp.h, xdisp.c: All uses changed.

303 304
	* editfns.c (Ftranslate_region_internal): Omit redundant test.

305 306 307 308 309 310
	* 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.

311
	* floatfns.c (Fexpt):
312 313
	* fileio.c (make_temp_name): Omit unnecessary cast to unsigned.

314 315 316
	* editfns.c (Ftranslate_region_internal): Use int, not EMACS_INT
	for characters.

317 318
	* doc.c (get_doc_string): Omit (unsigned)c that mishandled negatives.

319 320 321 322 323
	* 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.

324 325 326 327
	* 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.

328 329 330 331 332 333
	* 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.

334 335 336 337 338 339 340 341
	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.

342
	* character.c (char_string): Remove unnecessary casts.
343 344 345 346 347 348 349 350 351 352

	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.
	* data.c (Faset):

	(Fsubst_char_in_region):
	* fns.c (concat):
	* xdisp.c (decode_mode_spec_coding):
	Adjust to CHAR_STRING's new requirement.
	* editfns.c (Finsert_char, Fsubst_char_in_region):
	* fns.c (concat): Check that character args are actually
	characters.  Without this test, these functions did the wrong
	thing with wildly out-of-range values on 64-bit hosts.

363 364 365 366 367
	Remove incorrect casts to 'unsigned' that lose info on 64-bit hosts.
	These casts should not be needed on 32-bit hosts, either.
	* keyboard.c (read_char):
	* lread.c (Fload): Remove casts to unsigned.

368 369 370 371
	* lisp.h (UNSIGNED_CMP): New macro.
	This fixes comparison bugs on 64-bit hosts.
	(ASCII_CHAR_P): Use it.

	* composite.h (COMPOSITION_ENCODE_RULE_VALID):
	* dispextern.h (FACE_FROM_ID):
	* keyboard.c (read_char): Use UNSIGNED_CMP.

378 379 380
	* xmenu.c (dialog_selection_callback) [!USE_GTK]: Cast to intptr_t,
	not to EMACS_INT, to avoid GCC warning.

381 382
	* xfns.c (x_set_scroll_bar_default_width): Remove unused 'int' locals.

383 384 385
	* buffer.h (PTR_BYTE_POS, BUF_PTR_BYTE_POS): Remove harmful cast.
	The cast incorrectly truncated 64-bit byte offsets to 32 bits, and
	isn't needed on 32-bit machines.

	(total_intervals, total_strings, total_free_strings):
410 411 412 413
	Now EMACS_INT, not int.  All uses changed.
	(Fgarbage_collect): Compute overall total using a double, so that
	integer overflow is less likely to be a problem.  Check for overflow
	when converting back to an integer.
414 415 416 417
	(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;
	they were never used, so remove them instead of repairing them.

419 420 421

	(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

	* 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.

	* alloc.c (make_event_array): Use XINT, not XUINT.
	There's no need for unsigned here.

1295 1296 1297 1298
	* mem-limits.h (EXCEEDS_LISP_PTR) [!USE_LSB_TAG]: EMACS_UINT -> uintptr_t
	This follows up to the 2011-05-06 change that substituted uintptr_t
	for EMACS_INT.  This case wasn't caught back then.

	Rework Fformat to avoid integer overflow issues.
	* editfns.c: Include <float.h> unconditionally, as it's everywhere
	now (part of C89).  Include <verify.h>.
	(MAX_10_EXP, CONVERTED_BYTE_SIZE): Remove; no longer needed.
	(pWIDE, pWIDElen, signed_wide, unsigned_wide): New defns.
	(Fformat): Avoid the prepass trying to compute sizes; it was only
	approximate and thus did not catch overflow reliably.  Instead, walk
	through the format just once, formatting and computing sizes as we go,
	checking for integer overflow at every step, and allocating a larger
	buffer as needed.  Keep track separately whether the format is
	multibyte.  Keep only the most-recently calculated precision, rather
	than them all.  Record whether each argument has been converted to
	string.  Use EMACS_INT, not int, for byte and char and arg counts.
	Support field widths and precisions larger than INT_MAX.  Avoid
	sprintf's undefined behavior with conversion specifications such as %#d
	and %.0c.  Fix bug with strchr succeeding on '\0' when looking for
	flags.  Fix bug with (format "%c" 256.0).  Avoid integer overflow when
	formatting out-of-range floating point numbers with int
	formats. (Bug#8668)

	* lisp.h (FIXNUM_OVERFLOW_P): Work even if arg is a NaN.

	* data.c: Avoid integer truncation in expressions involving floats.
	* data.c: Include <intprops.h>.
	(arith_driver): When there's an integer overflow in an expression
	involving floating point, convert the integers to floating point
	so that the resulting value does not suffer from catastrophic
	integer truncation.  For example, on a 64-bit host (* 4
	most-negative-fixnum 0.5) should yield about -4.6e+18, not zero.
	Do not rely on undefined behavior after integer overflow.

	Rename from parse_str_to_multibyte; all uses changed.
1333 1334 1335 1336 1337 1338
	Check for integer overflow.
	* insdel.c, lisp.h (count_size_as_multibyte): Remove,
	since it's now a duplicate of the other.  This is more of
	a character than a buffer op, so better that it's in character.c.
	* fns.c, print.c: Adjust to above changes.
