	* regex.c: Suppress GCC warning on RHEL 6.  (Bug#11207)
	Conditionalize the pragmas on GCC 4.5 or later, not GCC 4.3 or later,
	since GCC 4.4.6 issues a bogus warning for them.

11 12 13 14 15 16 17 18
	Fix bugs in file timestamp newness comparisons.
	* fileio.c (Ffile_newer_than_file_p):
	* lread.c (Fload): Use full timestamp resolution of files,
	not just the 1-second resolution, so that files that are only
	slightly newer still count as newer.
	* fileio.c (Ffile_newer_than_file_p): Don't assume file
	timestamps fit in 'int'; this fixes a Y2038 bug on most hosts.

	* lisp.h (Fread_file_name): Restore EXFUN (it's not a normal DEFUN
	and did not make it into globals.h).

	Fix block vector allocation code to allow VECTOR_BLOCK_SIZE
	values which aren't power of 2.
	* alloc.c (VECTOR_FREE_LIST_SIZE_MASK): New macro.  Verify
	it's value and the value of VECTOR_BLOCK_SIZE.  Adjust users
	accordingly.

88 89 90 91 92 93
2012-07-03  Stefan Monnier  <monnier@iro.umontreal.ca>

2012-07-02  Paul Eggert  <eggert@cs.ucla.edu>

	* alloc.c (mark_object): Remove "#ifdef GC_CHECK_MARKED_OBJECTS"
	wrapper that is not needed because the wrapped code is a no-op (zero
	machine instructions) when GC_CHECK_MARKED_OBJECTS is not defined.
	This avoids a -Wunused-macros diagnostic with GCC 4.7.1 x86-64.

134 135 136 137
2012-07-02  Dmitry Antipov  <dmantipov@yandex.ru>

	objects.  Use CHECK_LIVE for all vector-like objects except buffers
139 140 141
	and subroutines when GC_CHECK_MARKED_OBJECTS is defined.  Avoid
	redundant calls to mark_vectorlike for bool vectors.

144 145
	* nsterm.m (ns_init_paths): Ignore site-lisp if --no-site-lisp.

146 147 148 149 150
	* epaths.in (PATH_SITELOADSEARCH): New.
	* lread.c (init_lread): Use PATH_SITELOADSEARCH.
	This is rather than relying on --enable-locallisppath elements
	having "site-lisp" in their names.  (Bug#10208#25, 11658)

151 152
2012-06-30  Eli Zaretskii  <eliz@gnu.org>

	* w32.c (emacs_gnutls_pull): Call select with one more argument.

157
	* sysselect.h [DOS_NT]: Don't include sys/select.h.
158
	(pselect) [!MS_DOS]: Redirect to sys_select.
159 160 161 162 163 164 165 166 167 168 169 170 171

	* sysdep.c: Don't include dos.h and dosfns.h.

	* process.c (sys_select):
	* msdos.c (sys_select): Accept one more argument and ignore it.

	* msdos.c (event_timestamp, sys_select): Use gnulib's gettime;
	adapt data types and code to that.

	* dosfns.c:
	* msdos.c (gettime, settime): Define away the prototypes in dos.h,
	which clashes with the gnulib function of the same name.

172 173
2012-06-30  Andreas Schwab  <schwab@linux-m68k.org>

174 175 176 177
	* font.c (font_style_to_value, font_style_symbolic)
	(font_prop_validate_style): Add type checks for values in
	font_style_table.

178 179 180 181 182

	* w32.c (getwd): Adjust commentary about startup_dir.
	(init_environment): Always call sys_access, even in non-MSVC
	builds.  Don't chdir to the directory of the Emacs executable.
	This undoes code from 1997 which was justified by the need to
	"avoid conflicts when removing and renaming directories".  But its
	downside was that every relative file name was being interpreted
	relative to the directory of the Emacs executable, which can never
	be TRT.  In particular, it broke sys_access when called with
	relative file names.
	(sys_access): Map GetLastError to errno.

198 199 200 201
2012-06-29  Dmitry Antipov  <dmantipov@yandex.ru>

	Adjust users accordingly.
	* xdisp.c (try_cursor_movement): Replace type check with eassert.
	* window.c (Fscroll_left, Fscroll_right): Change type of 'hscroll'

	Use sprintf return value instead of invoking strlen on result.
	In the old days this wasn't portable, since some sprintf
	implementations returned char *.  But they died out years ago and
	Emacs already assumes sprintf returns int.
	Similarly for float_to_string.
	This patch speeds up (number-to-string 1000) by 3% on Fedora 15 x86-64.

	Use sprintf or float_to_string result to avoid need to call strlen.
	* data.c (Fnumber_to_string):
	Use make_unibyte_string, since the string must be ASCII.
	* lisp.h, print.c (float_to_string): Now returns int length.
	* term.c (produce_glyphless_glyph):
	Use sprintf result rather than recomputing it.

410 411 412 413 414

2012-06-22  Paul Eggert  <eggert@cs.ucla.edu>

	Support higher-resolution time stamps (Bug#9000).
	The time stamps are only nanosecond-resolution at the C level,
	since that's the best that any real-world system supports now.
	But they are picosecond-resolution at the Lisp level, as that's
	easy, and leaves room for future OS improvements.

	* Makefile.in (LIB_CLOCK_GETTIME): New macro.
	(LIBES): Use it.

	* alloc.c (Fgarbage_collect): Port to higher-res time stamps.
	Don't get current time unless it's needed.

	* atimer.c: Include <sys/time.h> unconditionally, since gnulib
	now provides it if it's absent.
	(start_atimer): Port to higher-res time stamps.
	Check for time stamp overflow.  Don't get current time more
	often than is needed.

	* buffer.h (struct buffer): Buffer modtime now has high resolution.
	Include systime.h, not time.h.
	(NONEXISTENT_MODTIME_NSECS, UNKNOWN_MODTIME_NSECS): New macros.

	* dired.c: Include stat-time.h.
	(Ffile-attributes): File times now have higher resolution.

	* dispextern.h [HAVE_WINDOW_SYSTEM]: Include systime.h.
	(struct image): Timestamp now has higher resolution.

	* dispnew.c (PERIODIC_PREEMPTION_CHECKING): Remove, as Emacs always
	has at least microseconds now.  All uses removed.
	(update_frame, update_single_window, update_window, update_frame_1)
	(Fsleep_for, sit_for): Port to higher-resolution time stamps.

	* editfns.c (time_overflow): Now extern.
	(Fcurrent_time, Fget_internal_run_time, make_time, lisp_time_argument)
	(float-time, Fformat_time_string, Fcurrent_time_string)
	(Fcurrent_time_zone): Accept and generate higher-resolution
	time stamps.
	(make_time_tail, make_lisp_time, dissassemble_lisp_time)
	(decode_time_components, lisp_seconds_argument): New functions.
	(make_time): Now static.
	(lisp_time_argument): Now returns EMACS_TIME.  New arg ppsec.
	Report an error if the time is invalid, rather than having the caller
	do that.

	* fileio.c: Include <stat-time.h>
	(Fcopy_file): Copy higher-resolution time stamps.
	Prefer to set the time stamp via a file descriptor if that works.
	(Fset_file_times, Finsert_file_contents, Fwrite_region)
	(Fverify_visited_file_modtime, Fclear_visited_file_modtime)
	(Fvisited_file_modtime, Fset_visited_file_modtime):
	Support higher-resolution time stamps.

	* fns.c (Frandom): Use nanoseconds, not microseconds, for seed.

	* gtkutil.c (xg_maybe_add_timer): Port to higher-res time stamps.

	* image.c (prepare_image_for_display, clear_image_cache)
	(lookup_image): Port to higer-resolution time stamps.

	* keyboard.c (start_polling, bind_polling_period):
	Check for time stamp overflow.
	(read_char, kbd_buffer_get_event, timer_start_idle)
	(timer_stop_idle, timer_resume_idle, timer_check_2, timer_check)
	(Fcurrent_idle_time, init_keyboard, set_waiting_for_input):
	Port to higher-resolution time stamps.  Do not assume time_t is signed.
	(decode_timer): New function.  Timers are now vectors of length 9,
	not 8, to accommodate the picosecond component.
	(timer_check_2): Use it.

	* nsterm.m (select_timeout, timeval_subtract): Remove.
	(ns_timeout): Use Emacs's facilities for time stamp arithmetic,
	as they're a bit more accurate and handle overflow better.
	(ns_select): Change prototype to be compatible with pselect.
	(ns_select, ns_term_shutdown): Port to ns-resolution time stamps.
	* nsterm.h (ns_select): Adjust prototype.

	* msdos.c (EMACS_TIME_ZERO_OR_NEG_P): Remove, as it assumes
	us-resolution time stamps.
	(sys_select): Use the new EMACS_TIME_SIGN macro instead.

	* lread.c (read_filtered_event): Port to ns-resolution time stamps.

	* lisp.h (time_overflow): New decl.
	(wait_reading_process_output): First arg is now intmax_t, not int,
	to accommodate larger waits.

	* process.h (struct Lisp_Process.read_output_delay):
	Now counts nanoseconds, not microseconds.
	* process.c (ADAPTIVE_READ_BUFFERING): Don't worry about
	EMACS_HAS_USECS.
	(READ_OUTPUT_DELAY_INCREMENT, Faccept_process_output)
	(wait_reading_process_output):
	Port to ns-resolution time stamps.
	(Faccept_process_output, wait_reading_process_output):
	Check for time stamp overflow.  Do not assume time_t is signed.
	(select_wrapper): Remove; we now use pselect.
	(Fprocess_attributes): Now generates ns-resolution time stamps.

	* sysdep.c: Include utimens.h.  Don't include utime.h
	or worry about struct utimbuf; gnulib does that for us now.
	(gettimeofday): Remove; gnulib provides a substitute.
	(make_timeval): New function.
	(set_file_times): Now sets ns-resolution time stamps.
	New arg FD; all uses changed.
	(time_from_jiffies, ltime_from_jiffies, get_up_time)
	(system_process_attributes):
	Now returns ns-resolution time stamp.  All uses changed.
	Check for time stamp overflow.

	* sysselect.h: Don't depend on HAVE_SYS_SELECT_H; gnulib
	provides a substitute now.

	* systime.h: Include timespec.h rather than sys/time.h and time.h,
	since it guarantees struct timespec.
	(EMACS_TIME): Now struct timespec, so that we can support
	ns-resolution time stamps.
	(EMACS_TIME_RESOLUTION, LOG10_EMACS_TIME_RESOLUTION): New macros.
	(EMACS_HAS_USECS): Remove; Emacs always has sub-second time stamps now.
	(EMACS_USECS): Remove.
	(EMACS_SET_USECS): The underlying time stamp now has ns resolution,
	so multiply the arg by 1000 before storing it.
	(EMACS_NSECS, EMACS_SECS_ADDR, EMACS_SET_NSECS, EMACS_SET_SECS_NSECS):
	New macros.
	(EMACS_GET_TIME, EMACS_ADD_TIME, EMACS_SUB_TIME):
	Port to ns-resolution time stamps.
	(EMACS_TIME_NEG_P): Remove; replaced by....
	(EMACS_TIME_SIGN): New macro.
	(EMACS_SET_INVALID_TIME, EMACS_TIME_VALID_P)
	(EMACS_TIME_FROM_DOUBLE, EMACS_TIME_TO_DOUBLE): New macros.
	(set_file_times, make_time, lisp_time_argument): Adjust signature.
	(make_timeval, make_lisp_time, decode_time_components): New decls.
	(EMACS_TIME_CMP): Remove; no longer used.  Plus, it was buggy, in
	that it mishandled time_t overflow.  You can't compare by subtracting!
	(EMACS_TIME_EQ, EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE)
	(EMACS_TIME_LT, EMACS_TIME_LE): Rewrite in terms of timespec_cmp.

	* term.c: Include <sys/time.h>.
	(timeval_to_Time): New function, for proper overflow wraparound.
	(term_mouse_position, term_mouse_click): Use it.

	* undo.c (record_first_change): Support higher-resolution time stamps
	in the undo buffer.
	(Fprimitive_undo): Use them when restoring time stamps.

	* w32.c (ltime, U64_TO_LISP_TIME, process_times, emacs_gnutls_pull)
	(w32_get_internal_run_time):
	Port to higher-resolution Emacs time stamps.
	(ltime): Now accepts single 64-bit integer, as that's more convenient
	for callers.

	* xdisp.c (start_hourglass): Port to ns-resolution time stamps.

	* xgselect.c, xgselect.h (xg_select): Add sigmask argument,
	for compatibility with pselect.  Support ns-resolution time stamps.

	* xselect.c (wait_for_property_change, x_get_foreign_selection):
	Check for time stamp overflow, and support ns-resolution time stamps.

	* xterm.c: Don't include sys/time.h; gnulib does that for us now.
	Don't worry about whether HAVE_TIMEVAL and HAVE_SELECT are set.
	(timeval_subtract): Remove; no longer needed.
	(XTflash, XTring_bell, x_wait_for_event):
	Port to ns-resolution time stamps.  Don't assume time_t is signed.

	(LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
	Use an inline function on all platforms when using the union type,
	since this is simpler and 'static inline' can be used portably
	within Emacs now.
	(LISP_INITIALLY_ZERO): New macro.
	(XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
	(XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.

	For a 'struct window', replace some Lisp_Object fields to
	bitfields where appropriate, remove unused fields.
	* window.h (struct window): Remove unused 'last_mark_x' and

	Change type of 'force_start', 'optional_new_start',
	'last_had_star', 'update_mode_line' and 'start_at_line_beg'

	Only r_alloc_inhibit_buffer_relocation needed to be added;
	the others were already declared.

1395 1396 1397 1398 1399
	* bidi.c (bidi_mirror_char): Don't possibly truncate the integer

	defined on ralloc.c.

	* ralloc.c (r_alloc_inhibit_buffer_relocation): New function.

	* search.c (search_buffer): Use it to inhibit relocation of buffer
	text while re_search_2 is doing its job, because re_search_2 is

2012-05-26  Paul Eggert  <eggert@cs.ucla.edu>

	Fix coding-related core dumps with gcc -ftrapv.
	The code was computing A - B, where A and B are pointers, and B is
	random garbage.  This can lead to core dumps on platforms that
	have special pointer registers, and it also leads to core dumps on
	x86-64 when compiled with gcc -ftrapv.  The fix is to compute
	A - B only when B is initialized properly.
	* coding.c (coding_set_source, coding_set_destination): Return void.
	(coding_change_source, coding_change_destinations): New functions,
	with the old behaviors of coding_set_source and coding_set_destination.
	All callers that need an offset changed to use these new functions.

	* w32inevt.c: Include termchar.h and window.h.
	(do_mouse_event): Support mouse-autoselect-window.  When the mouse
	moves, call note_mouse_highlight.  If help_echo changed, call
	gen_help_event to produce help-echo message in the echo area.
	Call clear_mouse_face if mouse_face_hidden is set in the mouse

1603 1604 1605 1606 1607 1608 1609
	* charset.h (DECODE_CHAR): Return int, not unsigned;
	this is what was intended anyway, and it avoids undefined behavior.
	(CHARSET_OFFSET): Remove unused macro, instead of fixing its
	integer-overflow issues.
	(ENCODE_CHAR): Return unsigned on all hosts, not just on 32-bit hosts.
	Formerly, it returned EMACS_INT on 64-bit hosts in the common case
	where the argument is EMACS_INT, and this behavior is not intended.
1610 1611 1612 1613 1614 1615
	* chartab.c (Fmake_char_table, Fset_char_table_range)
	(uniprop_get_decoder, uniprop_get_encoder):
	Don't assume fixnum fits in int.
	* cmds.c (move_point): New function, that does the gist of
	Fforward_char and Fbackward_char, but does so while checking
	for integer overflow more accurately.
1616
	(Fforward_char, Fbackward_char): Use it.
1617 1618 1619 1620 1621 1622
	(Fforward_line, Fend_of_line, internal_self_insert)
	(internal_self_insert):
	Use ptrdiff_t, not EMACS_INT, where ptrdiff_t is wide enough.
	Fix a FIXME, by checking for integer overflow when calculating
	target_clm and actual_clm.
	* coding.c (detect_coding_XXX, encode_coding_XXX, CODING_DECODE_CHAR)
