22 23
	Fix some integer overflow issues, such as string length overflow.

24 25
	* insdel.c (count_size_as_multibyte): Check for string overflow.

26 27 28 29 30 31 32 33 34
	* character.c (lisp_string_width): Check for string overflow.
	Use EMACS_INT, not int, for string indexes and lengths; in
	particular, 2nd arg is now EMACS_INT, not int.  Do not crash if
	the resulting string length overflows an EMACS_INT; instead,
	report a string overflow if no precision given.  When checking for
	precision exhaustion, use a check that cannot possibly have
	integer overflow.  (Bug#8675)
	* character.h (lisp_string_width): Adjust to new signature.

35 36 37 38 39 40
	* alloc.c (string_overflow): New function.
	(Fmake_string): Use it.  This doesn't change behavior, but saves
	a few bytes and will simplify future changes.
	* character.c (string_escape_byte8): Likewise.
	* lisp.h (string_overflow): New decl.

41 42 43
	Fixups, following up to the user-interface timestamp change.
	* nsterm.m (last_mouse_movement_time, ns_mouse_position): Use Time
	for UI timestamps, instead of unsigned long.
44 45
	* msdos.c (mouse_get_pos): Likewise.
	* w32inevt.c (movement_time, w32_console_mouse_position): Likewise.
46 47 48
	* w32gui.h (Time): Define by including "systime.h" rather than by
	declaring it ourselves.  (Bug#8664)

49 50 51
	* dispextern.h (struct image): Don't assume time_t <= unsigned long.
	* image.c (clear_image_cache): Likewise.

52 53
	* term.c (term_mouse_position): Don't assume time_t wraparound.

54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76
	Be more systematic about user-interface timestamps.
	Before, the code sometimes used 'Time', sometimes 'unsigned long',
	and sometimes 'EMACS_UINT', to represent these timestamps.  This
	change causes it to use 'Time' uniformly, as that's what X uses.
	This makes the code easier to follow, and makes it easier to catch
	integer overflow bugs such as Bug#8664.
	* frame.c (Fmouse_position, Fmouse_pixel_position):
	Use Time, not unsigned long, for user-interface timestamps.
	* keyboard.c (last_event_timestamp, kbd_buffer_get_event): Likewise.
	(button_down_time, make_lispy_position, make_lispy_movement): Likewise.
	* keyboard.h (last_event_timestamp): Likewise.
	* menu.c (Fx_popup_menu) [!HAVE_X_WINDOWS]: Likewise.
	* menu.h (xmenu_show): Likewise.
	* term.c (term_mouse_position): Likewise.
	* termhooks.h (struct input_event.timestamp): Likewise.
	(struct terminal.mouse_position_hook): Likewise.
	* xmenu.c (create_and_show_popup_menu, xmenu_show): Likewise.
	* xterm.c (XTmouse_position, x_scroll_bar_report_motion): Likewise.
	* systime.h (Time): New decl.  Pull it in from <X11/X.h> if
	HAVE_X_WINDOWS, otherwise define it as unsigned long, which is
	what it was before.
	* menu.h, termhooks.h: Include "systime.h", for Time.

77 78 79 80 81 82 83
	* keyboard.c (make_lispy_event): Fix problem in integer overflow.
	Don't assume that the difference between two unsigned long values
	can fit into an integer.  At this point, we know button_down_time
	<= event->timestamp, so the difference must be nonnegative, so
	there's no need to cast the result if double-click-time is
	nonnegative, as it should be; check that it's nonnegative, just in
	case.  This bug is triggered when events are more than 2**31 ms

	apart (about 25 days).  (Bug#8664)
85

86
	* xselect.c (last_event_timestamp): Remove duplicate decl.
87
	(x_own_selection): Remove needless cast to unsigned long.
88

89 90 91
	* xmenu.c (set_frame_menubar): Use int, not EMACS_UINT, for indexes
	that always fit in int.  Use a sentinel instead of a counter, to
	avoid a temp and to allay GCC's concerns about possible int overflow.
92 93
	* frame.h (struct frame): Use int for menu_bar_items_used
	instead of EMACS_INT, since it always fits in int.
94

95 96
	* menu.c (grow_menu_items): Check for int overflow.

97 98
	* xmenu.c (set_frame_menubar): Don't mishandle vectors with no nils.

99 100 101 102 103 104 105 106 107
	* xterm.c: Use EMACS_INT for Emacs modifiers, and int for X modifiers.
	Before, the code was not consistent.  These values cannot exceed
	2**31 - 1 so there's no need to make them unsigned.
	(x_x_to_emacs_modifiers): Accept int and return EMACS_INT.
	(x_emacs_to_x_modifiers): Accept EMACS_INT and return int.
	(x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers
	as modifiers.
	* xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.

108 109 110 111 112
	* lisp.h (XINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_INT.
	(XUINT) [USE_LISP_UNION_TYPE]: Cast to EMACS_UINT.
	Otherwise, GCC 4.6.0 warns about printf (pI, XINT (...)),
	presumably because the widths might not match.

113 114
	* window.c (size_window): Avoid needless test at loop start.

115 116 117 118
2011-05-18  Courtney Bane  <emacs-bugs-7626@cbane.org>  (tiny change)

	* term.c (Fresume_tty): Restore hooks before reinitializing (bug#8687).

120 121 122

	* textprop.c (Fprevious_single_char_property_change): Doc fix (bug#8655).

124 125 126 127 128

	* w32term.c (w32_draw_fringe_bitmap): Rename local vars `left' and
	`width' to `bar_area_x' and `bar_area_width', respectively.
	(x_scroll_run): Take account of fringe background extension.

129 130
	* xterm.c (x_draw_fringe_bitmap) [USE_TOOLKIT_SCROLL_BARS]:
	Rename local vars `left' and `width' to `bar_area_x' and
131 132 133 134
	`bar_area_width', respectively.
	(x_scroll_run) [USE_TOOLKIT_SCROLL_BARS]: Take account of fringe
	background extension.

2011-05-10  Jim Meyering  <meyering@redhat.com>

	* xdisp.c (x_intersect_rectangles): Fix typo "the the -> the".

139 140 141 142 143
2011-05-10  Juanma Barranquero  <lekktu@gmail.com>

	* image.c (Finit_image_library): Return t for built-in image types,
	like pbm and xbm.  (Bug#8640)

144 145 146 147
2011-05-09  Andreas Schwab  <schwab@linux-m68k.org>

	* w32menu.c (set_frame_menubar): Fix submenu allocation.

148 149
2011-05-07  Eli Zaretskii  <eliz@gnu.org>

150 151 152 153
	* w32console.c (Fset_screen_color): Doc fix.
	(Fget_screen_color): New function.
	(syms_of_ntterm): Defsubr it.

154 155 156 157 158 159 160 161
	* callproc.c (call_process_cleanup): Don't close and unlink the
	temporary file if Fcall_process didn't create it in the first
	place.
	(Fcall_process): Don't create tempfile if stdout of the child
	process will be redirected to a file specified with `:file'.
	Don't try to re-open tempfile in that case, and set fd[0] to -1 as
	cue to call_process_cleanup not to close that handle.

2011-05-07  Ben Key  <bkey76@gmail.com>

	* makefile.w32-in: The bootstrap-temacs rule now makes use of
	one of two shell specific rules, either bootstrap-temacs-CMD or
	bootstrap-temacs-SH.  The bootstrap-temacs-SH rule is identical
	to the previous implementation of the bootstrap-temacs rule.
	The bootstrap-temacs-CMD rule is similar to the previous
	implementation of the bootstrap-temacs rule except that it
	makes use of the ESC_CFLAGS variable instead of the CFLAGS
	variable.

	These changes, along with some changes to nt/configure.bat,
	nt/gmake.defs, and nt/nmake.defs, are required to extend my
	earlier fix to add support for --cflags and --ldflags options
	that include quotes so that it works whether make uses cmd or
	sh as the shell.

2011-05-06  Michael Albinus  <michael.albinus@gmx.de>

	* dbusbind.c (QCdbus_type_unix_fd): Declare static.
	(xd_remove_watch): Don't check QCdbus_type_unix_fd for SYMBOLP, it
	is a constant.
	(Fdbus_init_bus, xd_read_queued_messages): Bus can be a symbol or
	a string.  Handle both cases.
	(Fdbus_call_method_asynchronously, Fdbus_register_signal)
	(Fdbus_register_method): Use Qinvalid_function.

2011-05-06  Juanma Barranquero  <lekktu@gmail.com>

	* makefile.w32-in: Update dependencies.
	(LISP_H): Add inttypes.h and stdin.h.
	(PROCESS_H): Add unistd.h.

202 203
	* image.c (Finit_image_library) [!HAVE_NTGUI]: Omit unused local.

204 205 206
	* term.c (vfatal): Remove stray call to va_end.
	It's not needed and the C Standard doesn't allow it here anyway.

207 208 209
	Use C99's va_copy to avoid undefined behavior on x86-64 GNU/Linux.
	* eval.c (verror): doprnt a copy of ap, not the original.  (Bug#8545)

210 211 212
	* eval.c (verror): OK to create a string of up to MOST_POSITIVE_FIXNUM
	bytes.

213 214
	* term.c: Don't include <stdarg.h>, as <lisp.h> does that.

215 216
	* callproc.c (Fcall_process): Use 'volatile' to avoid vfork clobbering.

217 218
	* process.c (Fformat_network_address): Fix typo: args2 -> *args2.

219 220
	* xmenu.c (set_frame_menubar): Fix typo: int * -> int (3 times).

221 222
	* coding.c (detect_coding_charset): Fix typo: * 2 -> *4 (Bug#8601).

223 224 225
	* 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).
227 228 229 230 231 232 233

	* 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)
235

236 237
	* doprnt.c (doprnt): Support arbitrary pI values, such as "I64".

238 239 240 241
	* 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.

242 243
	* lisp.h (EMACS_INT, EMACS_UINT, BITS_PER_EMACS_INT, pI): Simplify.

244 245 246
	* 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>.
247 248
	(xd_remove_watch, Fdbus_init_bus, xd_read_queued_messages):
	Use SYMBOLP-guarded XSYMBOL, not XPNTR.
249

250 251 252
	* lisp.h (EMACS_INTPTR): Remove.  All uses changed to intptr_t.
	(EMACS_UINTPTR): Likewise, with uintptr_t.

253 254 255 256
	* 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.
257 258
	However, temporarily disable this change unless the temporary
	symbol WIDE_EMACS_INT is defined.
259

260 261
	* lread.c, process.c: Do not include <inttypes.h>; lisp.h does it now.

262 263 264 265 266 267 268 269 270 271 272 273 274 275 276 277 278 279 280 281 282 283 284 285 286 287 288 289 290 291
	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.

292 293 294 295 296 297
	* 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.

298 299 300 301 302 303 304 305
	* 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.

306 307 308 309 310
	* 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 *.

311 312
	* eval.c (Fautoload): Don't double-shift a pointer.

313 314
	* fns.c (Frandom): Let EMACS_UINT be wider than unsigned long.

	Remove unused parameter `fildes'.
	* process.c (read_process_output, send_process): Don't pass it.

2011-05-04  Juanma Barranquero  <lekktu@gmail.com>

	Fix previous change: the library cache is defined in w32.c.

	Implement dynamic loading of GnuTLS on Windows.

	* gnutls.h (GNUTLS_EMACS_ERROR_NOT_LOADED): New macro.
	(emacs_gnutls_write, emacs_gnutls_read): Mark as extern.
	(emacs_gnutls_record_check_pending, emacs_gnutls_transport_set_errno):
	Declare.

	(syms_of_gnutls) <Qgnutls_dll>: Initialize and staticpro it.
	(syms_of_gnutls) <Sgnutls_available_p>: defsubr it.

	* image.c: Include w32.h.
	(Vimage_type_cache): Delete.
	(syms_of_image) <Vimage_type_cache>: Don't initialize and staticpro it.
	(CACHE_IMAGE_TYPE, Finit_image_library): Use Vlibrary_cache instead.

	* lisp.h: Fix a problem with aliasing and vector headers.  (Bug#8546)
551 552

	For example, if b is of type struct buffer * and v of type struct
553 554 555 556 557
	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

	* 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.

	(isfloat_string): Remove.
613
	* lread.c: Include <inttypes.h>, for uintmax_t and strtoumax.
614
	(read1): Do not accept +. and -. as integers; this
615 616 617 618 619 620 621
	appears to have been a coding error.  Similarly, do not accept
	strings like +-1e0 as floating point numbers.  Do not report

	This function checks for valid syntax and produces the resulting
	Lisp float number too.  Rework it so that string-to-number
628
	no longer mishandles examples like "1.0e+".  Use strtoumax,

	These assumptions hold on all porting targets that I know of, but
	they are not guaranteed, they're easy to remove, and removing them
	makes further changes easier.
