	* process.c (Fformat_network_address): Fix typo: args2 -> *args2.

5 6
	* xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).

7 8
	* coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).

	* charset.h (struct charset.code_space): Now has 15 elements, not 16.
	* charset.c (Fdefine_charset_internal): Don't initialize
	charset.code_space[15].  The value was garbage, on hosts with

	32-bit int (Bug#8600).
13 14 15 16 17 18 19

	* lread.c (read_integer): Be more consistent with string-to-number.
	Use string_to_number to do the actual conversion; this avoids
	rounding errors and fixes some other screwups.  Without this fix,
	for example, #x1fffffffffffffff was misread as -2305843009213693952.
	(digit_to_number): Move earlier, for benefit of read_integer.
	Return -1 if the digit is out of range for the base, -2 if it is

	not a digit in any supported base.  (Bug#8602)

22 23
	* doprnt.c (doprnt): Support arbitrary pI values, such as "I64".

24 25 26 27
	* dispnew.c (scrolling_window): Return 1 if we scrolled,
	to match comment at start of function.  This also removes a
	GCC warning about overflow in a 32+64-bit port.

28 29
	* lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.

30 31 32 33 34 35
	* dbusbind.c: Do not use XPNTR on a value that may be an integer.
	Reported by Stefan Monnier in
	<http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00919.html>.
	(xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages): Use
	SYMBOLP-guarded XSYMBOL, not XPNTR.

36 37 38
	* lisp.h (EMACS_INTPTR): Remove.  All uses changed to intptr_t.
	(EMACS_UINTPTR): Likewise, with uintptr_t.

39 40 41 42 43
	* lisp.h: Prefer 64-bit EMACS_INT if available.
	(EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Define to 64-bit
	on 32-bit hosts that have 64-bit int, so that they can access
	large files.

44 45
	* lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.

46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75
	Prefer intptr_t/uintptr_t for integers the same widths as pointers.
	This removes an assumption that EMACS_INT and long are the same
	width as pointers.  The assumption is true for Emacs porting targets
	now, but we want to make other targets possible.
	* lisp.h: Include <inttypes.h>, for INTPTR_MAX, UINTPTR_MAX.
	(EMACS_INTPTR, EMACS_UINTPTR): New macros.
	In the rest of the code, change types of integers that hold casted
	pointers to EMACS_INTPTR and EMACS_UINTPTR, systematically
	replacing EMACS_INT, long, EMACS_UINT, and unsigned long.
	(XTYPE): Don't cast arg to EMACS_UINT; normally is not needed.
	(XSET): Cast type of XTYPE arg to EMACS_INTPTR; it is needed here.
	No need to cast type when ORing.
	(XPNTR): Return a value of type EMACS_INTPTR or EMACS_UINTPTR.
	* alloc.c (lisp_align_malloc): Remove a no-longer-needed cast.
	* doc.c (store_function_docstring): Use EMACS_INTPTR, so as not to
	assume EMACS_INT is the same width as char *.
	* gtkutil.c (xg_gtk_scroll_destroy, xg_tool_bar_button_cb):
	(xg_tool_bar_callback, xg_tool_bar_help_callback, xg_make_tool_item):
	Remove no-longer-needed casts.
	(xg_create_scroll_bar, xg_tool_bar_button_cb, xg_tool_bar_callback):
	(xg_tool_bar_help_callback, xg_make_tool_item):
	Use EMACS_INTPTR to hold an integer
	that will be cast to void *; this can avoid a GCC warning
	if EMACS_INT is not the same width as void *.
	* menu.c (find_and_call_menu_selection): Remove no-longer-needed cast.
	* xdisp.c (display_echo_area_1, resize_mini_window_1):
	(current_message_1, set_message_1):
	Use a local to convert to proper width without a cast.
	* xmenu.c (dialog_selection_callback): Likewise.

76 77 78 79 80 81
	* sysdep.c (get_random): Don't assume EMACS_INT is no wider than long.
	Also, don't assume VALBITS / RAND_BITS is less than 5,
	and don't rely on undefined behavior when shifting a 1 left into
	the sign bit.
	* lisp.h (get_random): Change signature to match.

82 83 84 85 86 87 88 89
	* lread.c (hash_string): Use size_t, not int, for hash computation.
	Normally we prefer signed values; but hashing is special, because
	it's better to use unsigned division on hash table sizes so that
	the remainder is nonnegative.  Also, size_t is the natural width
	for hashing into memory.  The previous code used 'int', which doesn't
	retain enough info to hash well into very large tables.
	(oblookup, oblookup_last_bucket_number, Funintern): Likewise.

90 91 92 93 94
	* dbusbind.c: Don't possibly lose pointer info when converting.
	(xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
	Use XPNTR rather than XHASH, so that the high-order bits of
	the pointer aren't lost when converting through void *.

95 96
	* eval.c (Fautoload): Don't double-shift a pointer.

97 98
	* fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.

99 100 101 102

	(Qgnutls_x509pki, Qgnutls_e_interrupted, Qgnutls_e_again)
	(Qgnutls_e_invalid_session, Qgnutls_e_not_ready_for_handshake)

	(Qgnutls_bootprop_hostname, Qgnutls_bootprop_verify_flags)
	(Qgnutls_bootprop_verify_error, Qgnutls_bootprop_verify_hostname_error)
	(Qgnutls_bootprop_callbacks_verify): Make static.

2011-05-01  Lars Magne Ingebrigtsen  <larsi@gnus.org>

	* sysdep.c (interruptible_wait_for_termination): New function
	which is like wait_for_termination, but allows keyboard
	interruptions.

	* callproc.c (Fcall_process): Add (:file "file") as an option for
	the STDOUT buffer.
	(Fcall_process_region): Ditto.

135 136 137
	* dosfns.c (Fint86, Fdos_memget, Fdos_memput): Use `ASIZE (FOO)'
	rather than `XVECTOR (FOO)->size'.

138 139 140 141
	* process.c: Remove HAVE_INTTYPES_H condition from inclusion of
	inttypes.h, as a gnulib replacement is used if it not available in
	system headers.

2011-04-21  Eli Zaretskii  <eliz@gnu.org>

	Lift the MOST_POSITIVE_FIXNUM/4 limitation on visited files.
	* fileio.c (Finsert_file_contents): Don't limit file size to 1/4
	of MOST_POSITIVE_FIXNUM.  (Bug#8528)

	* coding.c (coding_alloc_by_realloc): Error out if destination
	will grow beyond MOST_POSITIVE_FIXNUM.
	(decode_coding_emacs_mule): Abort if there isn't enough place in
	charbuf for the composition carryover bytes.  Reserve an extra
	space for up to 2 characters produced in a loop.
	(decode_coding_iso_2022): Abort if there isn't enough place in
	charbuf for the composition carryover bytes.

	aborting when %lld or %lll format is passed.
	[!HAVE_UNSIGNED_LONG_LONG_INT]: Error out instead of aborting when
	%llo or %llx format is passed.  (Bug#8545)

163 164 165
	* window.c (window_scroll_line_based): Use a marker instead of
	simple variables to record original value of point.  (Bug#7952)

166 167 168
	* doprnt.c (doprnt): Fix the case where a multibyte sequence
	produced by %s or %c overflows available buffer space.  (Bug#8545)

169 170 171
2011-04-28  Paul Eggert  <eggert@cs.ucla.edu>

	* doprnt.c (doprnt): Omit useless test; int overflow check (Bug#8545).

	Improve `doprnt' and its usage.  (Bug#8545)
	* doprnt.c (doprnt): Make sure `format' is never accessed beyond
	`format_end'.  Remove support for %l as a conversion specifier.
	Don't use xrealloc.  Improve diagnostics when the %l size modifier
	is used.  Update the commentary.

	* eval.c (verror): Simplify calculation of size_t.

	* coding.c (Ffind_operation_coding_system): Fix diagnostic error
	messages.

	* lisp.h: Fix a problem with aliasing and vector headers.  (Bug#8546)
237 238 239 240 241 242 243
	GCC 4.6.0 optimizes based on type-based alias analysis.  For
	example, if b is of type struct buffer * and v of type struct
	Lisp_Vector *, then gcc -O2 was incorrectly assuming that &b->size
	!= &v->size, and therefore "v->size = 1; b->size = 2; return
	v->size;" must therefore return 1.  This assumption is incorrect
	for Emacs, since it type-puns struct Lisp_Vector * with many other
	types.  To fix this problem, this patch adds a new type struct

	vectorlike_header that documents the constraints on layout of vectors
245 246 247
	and pseudovectors, and helps optimizing compilers not get fooled
	by Emacs's type punning.  It also adds the macros XSETTYPED_PVECTYPE
	XSETTYPED_PSEUDOVECTOR, TYPED_PSEUDOVECTORP, for similar reasons.

	* lisp.h (XSETTYPED_PVECTYPE): New macro, specifying the name of
	the size member.
250 251 252 253 254
	(XSETPVECTYPE): Rewrite in terms of new macro.
	(XSETPVECTYPESIZE): New macro, specifying both type and size.
	This is a bit clearer, and further avoids the possibility of
	undesirable aliasing.
	(XSETTYPED_PSEUDOVECTOR): New macro, specifying the size.

Paul Eggert committed
255
	(XSETPSEUDOVECTOR): Rewrite in terms of XSETTYPED_PSEUDOVECTOR.

Paul Eggert committed
258 259 260 261
	(ASIZE): Now uses header.size rather than size.  All
	previous uses of XVECTOR (foo)->size replaced to use this macro,
	to avoid the hassle of writing XVECTOR (foo)->header.size.
	(struct vectorlike_header): New type.
262 263 264 265 266 267 268
	(TYPED_PSEUDOVECTORP): New macro, also specifying the C type of the
	object, to help avoid aliasing.
	(PSEUDOVECTORP): Rewrite in terms of TYPED_PSEUDOVECTORP.
	(SUBRP): Likewise, since Lisp_Subr is a special case.
	* lisp.h (struct Lisp_Vector, struct Lisp_Char_Table):
	(struct Lisp_Sub_Char_Table, struct Lisp_Bool_Vector):
	(struct Lisp_Hash_Table): Combine first two members into a single

	changed to be "header.size" and "header.next".
	* buffer.h (struct buffer): Likewise.
	* font.h (struct font_spec, struct font_entity, struct font): Likewise.
	* frame.h (struct frame): Likewise.
	* process.h (struct Lisp_Process): Likewise.
	* termhooks.h (struct terminal): Likewise.
	* window.c (struct save_window_data, struct saved_window): Likewise.
	* window.h (struct window): Likewise.
	* alloc.c (allocate_buffer, Fmake_bool_vector, allocate_pseudovector):
	Use XSETPVECTYPESIZE, not XSETPVECTYPE, to avoid aliasing problems.
	* buffer.c (init_buffer_once): Likewise.
	* lread.c (defsubr): Use XSETTYPED_PVECTYPE, since Lisp_Subr is a

	Make the Lisp reader and string-to-float more consistent (Bug#8525)
289 290 291 292 293 294 295 296 297 298
	* data.c (atof): Remove decl; no longer used or needed.
	(digit_to_number): Move to lread.c.
	(Fstring_to_number): Use new string_to_number function, to be
	consistent with how the Lisp reader treats infinities and NaNs.
	Do not assume that floating-point numbers represent EMACS_INT
	without losing information; this is not true on most 64-bit hosts.
	Avoid double-rounding errors, by insisting on integers when
	parsing non-base-10 numbers, as the documentation specifies.
	* lisp.h (string_to_number): New decl, replacing ...
	(isfloat_string): Remove.
299
	* lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
300
	(read1): Do not accept +. and -. as integers; this
301 302 303 304 305 306 307 308 309 310 311 312 313
	appears to have been a coding error.  Similarly, do not accept
	strings like +-1e0 as floating point numbers.  Do not report
	overflow for integer overflows unless the base is not 10 which
	means we have no simple and reliable way to continue.
	Break out the floating-point parsing into a new
	function string_to_number, so that Fstring_to_number parses
	floating point numbers consistently with the Lisp reader.
	(digit_to_number): Moved here from data.c.  Make it static inline.
	(E_CHAR, EXP_INT): Remove, replacing with ...
	(E_EXP): New macro, to solve the "1.0e+" problem mentioned below.
	(string_to_number): New function, replacing isfloat_string.
	This function checks for valid syntax and produces the resulting
	Lisp float number too.  Rework it so that string-to-number
314
	no longer mishandles examples like "1.0e+".  Use strtoumax,
315 316
	so that overflow for non-base-10 numbers is reported only when
	there's no portable and simple way to convert to floating point.
317

318 319 320
	* textprop.c (set_text_properties_1): Rewrite for clarity,
	and to avoid GCC warning about integer overflow.

321 322 323 324 325 326
	* intervals.h (struct interval): Use EMACS_INT for members
	where EMACS_UINT might cause problems.  See
	<http://lists.gnu.org/archive/html/emacs-devel/2011-04/msg00514.html>.
	(CHECK_TOTAL_LENGTH): Remove cast to EMACS_INT; no longer needed.
	* intervals.c (interval_deletion_adjustment): Now returns EMACS_INT.
	All uses changed.
327 328
	(offset_intervals): Tell GCC not to worry about length overflow
	when negating a negative length.
329

330 331 332

	(overrun_check_free): Likewise.

333 334 335 336
	* alloc.c (SDATA_SIZE) [!GC_CHECK_STRING_BYTES]: Avoid runtime check
	in the common case where SDATA_DATA_OFFSET is a multiple of Emacs
	word size.

337 338 339 340 341 342
	* gnutls.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
	(gnutls_make_error): Rename local to avoid shadowing.
	(gnutls_emacs_global_deinit): ifdef out; not used.
	(Fgnutls_boot): Use const for pointer to readonly storage.
	Comment out unused local.  Fix pointer signedness problems.

343 344 345 346
	* lread.c (openp): Don't stuff size_t into an 'int'.
	Use <= on length, not < on length + 1, to avoid GCC 4.6.0 warning
	about possible signed overflow.

347 348 349 350 351
	* gtkutil.c: Fix problems found by GCC 4.6.0 on Ubuntu 10.10.
	(GDK_KEY_g): Don't define if already defined.
	(xg_prepare_tooltip): Avoid pointer signedness problem.
	(xg_set_toolkit_scroll_bar_thumb): Redo to avoid two casts.

352 353 354
	* process.c (Fnetwork_interface_info): Avoid left-shift undefined
	behavior with 1 << 31.  GCC 4.6.0 warns about this on 32-bit hosts.

355 356 357 358
	* xfns.c (Fx_window_property): Simplify a bit,
	to make a bit faster and to avoid GCC 4.6.0 warning.
	* xselect.c (x_get_window_property, x_handle_dnd_message): Likewise.

359 360
	* fns.c (internal_equal): Don't assume size_t fits in int.

361 362
	* alloc.c (compact_small_strings): Tighten assertion a little.

	Replace pEd with more-general pI, and fix some printf arg casts.
	* lisp.h (pI): New macro, generalizing old pEd macro to other
	conversion specifiers.  For example, use "...%"pI"d..." rather
	than "...%"pEd"...".
	(pEd): Remove.  All uses replaced with similar uses of pI.
	* src/m/amdx86-64.h, src/m/ia64.h, src/m/ibms390x.h: Likewise.
	* alloc.c (check_pure_size): Don't overflow by converting size to int.
	* bidi.c (bidi_dump_cached_states): Use pI to avoid cast.
	* data.c (Fnumber_to_string): Use pI instead of if-then-else-abort.
	* dbusbind.c (xd_append_arg): Use pI to avoid cast.
	(Fdbus_method_return_internal, Fdbus_method_error_internal): Likewise.

	* lisp.h (DEFINE_FUNC): Make sname 'static'.

1187 1188 1189 1190 1191
	Make Emacs functions such as Fatom 'static' by default.
	This makes it easier for human readers (and static analyzers)
	to see whether these functions can be called from other modules.
	DEFUN now defines a static function.  To make the function external
	so that it can be used in other C modules, use the new macro DEFUE.

	strlen and xstrcasecmp that expect char *, which does not
	conform to the C standard.
	(get_adstyle_property, ftfont_pattern_entity): Use FcChar8 for
	arguments to FcPatternGetString, and explicitly cast FcChar8 * to
	char * when the C standard requires it.
