This implements a suggestion made in:
http://lists.gnu.org/archive/html/emacs-devel/2014-10/msg00587.html
Among other things, this means timer.el no longer needs to
autoload the time-date module.
* doc/lispref/os.texi (Time of Day, Time Conversion, Time Parsing)
(Processor Run Time, Time Calculations):
Document the new behavior, plus be clearer about the old behavior.
(Idle Timers): Take advantage of new functionality.
* etc/NEWS: Document the changes.
* lisp/allout-widgets.el (allout-elapsed-time-seconds): Doc fix.
* lisp/arc-mode.el (archive-ar-summarize):
* lisp/calendar/time-date.el (seconds-to-time, days-to-time, time-since):
* lisp/emacs-lisp/timer.el (timer-relative-time, timer-event-handler)
(run-at-time, with-timeout-suspend, with-timeout-unsuspend):
* lisp/net/tramp.el (tramp-time-less-p, tramp-time-subtract):
* lisp/proced.el (proced-time-lessp):
* lisp/timezone.el (timezone-time-from-absolute):
* lisp/type-break.el (type-break-schedule, type-break-time-sum):
Simplify by using new functionality.
* lisp/calendar/cal-dst.el (calendar-next-time-zone-transition):
Do not return time values in obsolete and undocumented (HI . LO)
format; use (HI LO) instead.
* lisp/calendar/time-date.el (with-decoded-time-value):
Treat 'nil' as current time. This is mostly for XEmacs.
(encode-time-value, with-decoded-time-value): Obsolete.
(time-add, time-subtract, time-less-p): Use no-op autoloads, for
XEmacs. Define only if XEmacs, as they're now C builtins in Emacs.
* lisp/ldefs-boot.el: Update to match new time-date.el
* lisp/proced.el: Do not require time-date.
* src/editfns.c (invalid_time): New function.
Use it instead of 'error ("Invalid time specification")'.
(time_add, time_subtract, time_arith, Ftime_add, Ftime_less_p)
(decode_float_time, lisp_to_timespec, lisp_time_struct):
New functions.
(make_time_tail, make_time): Remove. All uses changed to use
new functions or plain list4i.
(disassemble_lisp_time): Return effective length if successful.
Check that LOW is an integer, if it's combined with other components.
(decode_time_components): Decode into struct lisp_time, not
struct timespec, so that we can support a wide set of times
regardless of whether time_t is signed. Decode plain numbers
as seconds since the Epoch, and nil as the current time.
(lisp_time_argument, lisp_seconds_argument, Ffloat_time):
Reimplement in terms of new functions.
(Fencode_time): Just use list2i.
(syms_of_editfns): Add time-add, time-subtract, time-less-p.
* src/keyboard.c (decode_timer): Don't allow the new formats (floating
point or nil) in timers.
* src/systime.h (LO_TIME_BITS): New constant. Use it everywhere in
place of the magic number '16'.
(struct lisp_time): New type.
(decode_time_components): Use it.
(lisp_to_timespec): New decl.
* doc/lispref/text.texi (Special Properties): Mention `inhibit-read-only'.
* src/buffer.c (Fbarf_if_buffer_read_only): Don't raise an error if
the text at POSITION (new optional argument) has the
`inhibit-read-only' text property set.
* src/callint.c (Fcall_interactively): Pass in nil as argument to
Fbarf_if_buffer_read_only.
* src/fileio.c (Finsert_file_contents): Ditto.
* src/insdel.c (prepare_to_modify_buffer_1): Pass start region in.
* src/intervals.h (INTERVAL_WRITABLE_P): Check the `inhibit-read-only'
text property.
* src/textprop.c (verify_interval_modification): Check buffer
readedness after the last interval.
Fixes: 18993
* nsterm.m (ns_send_appdefined): Check for application defined
event on Cocoa (Bug#18993).
(run): Restore code before the previous 18993 fix.
src/window.c (window_scroll_pixel_based): Avoid truncation/rounding
errors in computing the number of pixels to scroll. Suggested by
Kelly Dean <kelly@prtime.org>.
OS X 10.10 will, at times, not send us the application-defined
event that is used to terminate the event loop. As a workaround,
we define a timeout and react accordingly. Leaving it in place
for other OSX and NS versions as a safety net.
Partial revert of 2014-11-08T16:32:37Z!jan.h.d@swipnet.se.
Fixes debbugs:18993
* xfont.c (xfont_list_pattern): Do not allocate font entity object
for each candidate font but attempt to reuse it from previous improper
candidate, if any.
* image.c (CT_HASH_RGB) [COLOR_TABLE_SUPPORT]: Remove, replacing with ...
(ct_hash_rgb) [COLOR_TABLE_SUPPORT]: New function. All uses changed.
This function avoids undefined behavior with signed shift overflow.
* nsterm.m (init): Replace OSX 10.9 check with IMPL_COCOA.
(run): Ditto. Only use non-system event loop if OSX version is
exactly 10.9.
Fixes: debbugs:18993
* frame.c (adjust_frame_size): Call x_set_window_size only if
f->can_x_set_window_size is set.
(make_frame): Initialize f->can_x_set_window_size and
f->can_run_window_configuration_change_hook.
(Fcan_run_window_configuration_change_hook): New function.
* frame.h (frame): Split `official' into `can_x_set_window_size'
and `can_run_window_configuration_change_hook'.
* nsfns.m (Fx_create_frame): Set f->can_x_set_window_size.
* w32fns.c (Fx_create_frame, x_create_tip_frame): Set
f->can_x_set_window_size.
* window.c (run_window_configuration_change_hook): Return
immediately if either f->can_x_set_window_size or
f->can_run_window_configuration_change_hook are false.
(Fset_window_configuration): Instead of f->official set
f->can_x_set_window_size.
* xfns.c (Fx_create_frame, x_create_tip_frame): Set
f->can_x_set_window_size.
* faces.el (face-set-after-frame-default): Enable running
`window-configuration-change-hook'.
* frame.c (Qsize):
* w32notify.c (Qsize): Remove.
* lisp.h (Qsize): New decl.
* lread.c (Qsize): Now extern.
* w32notify.c (syms_of_w32notify): No need to defsym.
src/xdisp.c (Fdump_glyph_matrix, Fdump_frame_glyph_matrix): Doc fix.
(Fdump_frame_glyph_matrix): Don't segfault if invoked on a GUI
frame; instead, print an error message.
src/keyboard.c (readable_events): When FLAGS include
READABLE_EVENTS_FILTER_EVENTS, ignore BUFFER_SWITCH_EVENT events.
This avoids returning non-nil from input-pending-p when only such
events are in the queue.
