	Port to OpenBSD 5.1 amd64.
	* sysdep.c [BSD_SYSTEM]: Include <sys/param.h> before <sys/sysctl.h>.
	This is needed for OpenBSD, and should be harmless on all BSD systems.
	Also, include <sys/sysctl.h>, as it should be available on all
	BSD_SYSTEM hosts given that we're already calling sysctl in that case.
	(list_system_processes) [__OpenBSD__]: Use DARWIN_OS style mib, but
	use p_pid member, not kp_proc.pid.

	* xterm.c:
	Omit needless casts involving void * pointers and allocation.
	Prefer "P = xmalloc (sizeof *P)" to "P = xmalloc (sizeof (TYPE_OF_P))",
	as the former is more robust if P's type is changed.
	Prefer xzalloc to xmalloc + memset 0.
	Simplify malloc-or-realloc to realloc.
	Don't worry about xmalloc returning a null pointer.
	Prefer xstrdup to xmalloc + strcpy.

	* xdisp.c (display_line): Fix horizontal pixel coordinates when
	hscroll is larger than the line width.  Fixes long and futile
	looping inside extend_face_to_end_of_line (on a TTY) producing
	glyphs that are not needed and thrown away.

157 158 159 160 161
	* window.c (set_window_hscroll): Revert the 100000 hscroll limit.
	This should be fixed in a better way; see Eli Zaretskii in
	<http://lists.gnu.org/archive/html/emacs-devel/2012-07/msg00088.html>.
	(HSCROLL_MAX): Remove; this is now internal to set_window_hscroll.

162 163 164 165
	* fileio.c (time_error_value): Rename from special_mtime.

166 167 168 169 170
	* emacs.c (gdb_pvec_type): Change it back to enum pvec_type.
	This variable's comment says Emacs needs at least one GDB-visible
	symbol of type enum pvec_type, to work around GDB problems.
	The symbol's value doesn't matter.

171 172 173

	Avoid weird behavior with large horizontal scrolls.
	Without this change, for example, large hscroll values would
	mess up Emacs's display on Fedora 15 x86, presumably due to
	overflows in int calculations in the display code.
	Also, if buffers had long lines, Emacs would freeze.
	* window.c (HSCROLL_MAX): Reduce to 100000, and make it visible to GDB.
	(set_window_hscroll): New function, containing the old guts of
	Fset_window_hscroll.  Return the clipped value.
	(Fset_window_hscroll, Fscroll_left, Fscroll_right): Use it.
	This avoids the need to check against PTRDIFF_MAX.

241 242 243 244
	* 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.

245 246 247 248 249 250 251 252
	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.

	* 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.

	* 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.

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.

	* xmenu.c (x_menu_wait_for_event): 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.

	as the union type is for debugging, not for production.
	(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.

2012-05-28  Paul Eggert  <eggert@cs.ucla.edu>

	* bidi.c (bidi_mirror_char): Put eassert before conversion to int.
	This avoids undefined behavior that might cause the eassert
	to not catch an out-of-range value.

1609 1610 1611 1612 1613
2012-05-28  Juanma Barranquero  <lekktu@gmail.com>

	* unexmacosx.c (copy_data_segment): Truncate after 16 characters
	when referring to sectname field in printf format.

1623 1624
2012-05-27  Paul Eggert  <eggert@cs.ucla.edu>

1625 1626 1627 1628
	* lisp.h [REL_ALLOC]: Omit duplicate prototypes.
	Only r_alloc_inhibit_buffer_relocation needed to be added;
	the others were already declared.

1629 1630 1631 1632 1633
	* bidi.c (bidi_mirror_char): Don't possibly truncate the integer
	before checking whether it's out of range.  Put the check inside
	eassert.  See
	<http://lists.gnu.org/archive/html/emacs-devel/2012-05/msg00485.html>.

	* callproc.c (Fcall_process): Restore a line that was accidentally
	commented out in the 2011-02-13 change (bug#11547).

1639
2012-05-27  Eli Zaretskii  <eliz@gnu.org>
1640 1641 1642 1643 1644 1645 1646 1647 1648 1649 1650 1651 1652 1653

	* lisp.h [REL_ALLOC]: Add prototypes for external functions
	defined on ralloc.c.

	* buffer.c [REL_ALLOC]: Remove prototypes of
	r_alloc_reset_variable, r_alloc, r_re_alloc, and r_alloc_free,
	they are now on lisp.h.

	* 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
	passed C pointers to buffer text.  (Bug#11519)

1654 1655 1656
	* msdos.c (internal_terminal_init) <Vwindow_system_version>:
	Update value to 24.

1657 1658 1659 1660 1661 1662 1663 1664
	* xdisp.c (move_it_to): Under MOVE_TO_Y, when restoring iterator
	state after an additional call to move_it_in_display_line_to, keep
	the values of it->max_ascent and it->max_descent found for the
	entire line.
	(pos_visible_p): Revert the comparison against bottom_y to what it
	was in revid eliz@gnu.org-20120513182235-4p6386j761ld0nwb.
	(Bug#11464)

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.

1678 1679 1680 1681
2012-05-26  Glenn Morris  <rgm@gnu.org>

	* nsterm.m (ns_init_paths): Don't mess with INFOPATH.  (Bug#2791)

1682 1683
2012-05-26  Eli Zaretskii  <eliz@gnu.org>

1684
	Extend mouse support on W32 text-mode console.
1685 1686
	* xdisp.c (draw_row_with_mouse_face):
	Call tty_draw_row_with_mouse_face for WINDOWSNT as well.
1687 1688

	* w32console.c: Include window.h.
1689 1690
	(w32con_write_glyphs_with_face, tty_draw_row_with_mouse_face):
	New functions.
1691 1692
	(initialize_w32_display): Initialize mouse-highlight data.

1693 1694 1695 1696 1697 1698 1699
	* 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
	highlight info.

1700 1701 1702 1703 1704
2012-05-26  Paul Eggert  <eggert@cs.ucla.edu>

	* lread.c (read1): Simplify slightly to avoid an overflow warning
	with GCC 4.7.0 on x86-64.
