* src/atimer.c (start_atimer, turn_on_atimers):
Rewrite memset+assignments to xzalloc or initializers.
|
|
* src/w32proc.c (w32_raise): A more complete, Posix-compliant
implementation.
(sys_signal): Support SIGBREAK.
* src/syssignal.h (raise): Redirect to 'w32_raise'.
* src/atimer.c: Don't redirect 'raise', now done in syssignal.h.
(Bug#80760)

* src/w32proc.c (w32_raise): New function.
* src/atimer.c (raise) [WINDOWSNT]: Redirect to 'w32_raise'.
|
|
* src/atimer.c (set_alarm): If the atimer has already expired, signal
it right away instead of postponing it further. Previously this could
occur repeatedly, blocking atimers indefinitely.
Also only use `alarm` as fallback if `setitimer` is unavailable, not
both at the same time (which makes no sense, and they both typically
use the same mechanism behind the curtains).
* test/src/eval-tests.el (eval-tests/funcall-with-delayed-message):
New test, verifying proper functioning of funcall-with-delayed-message
which also serves as test for this bug (which also caused
debug-timer-check to fail, but that test is only run when Emacs is
built with enable-checking).

* src/atimer.c (set_alarm): Try to start a POSIX timer before
starting a timerfd timer. On Cygwin, return if the POSIX timer is
started successfully. (Bug#51734)
|
|
* src/atimer.c (set_alarm) [CYGWIN]: Don't start both timerfd and
alarms; this causes a slowdown. (Bug#51734)
|
|
* src/atimer.c (set_alarm): Actually start both timerfd and
alarms (attempted in 4107549a).
|
|
|
|
* src/atimer.c (init_atimer): Always start the SIGALRM alarms,
even if we're using timerfd (bug#19776). See long, long
discussion in the bug report for why this is necessary.

itimerspec works. POSIX no longer requires support for the
obsolescent setitimer function.

This fixes some URLs I omitted from my previous pass,
notably those in lists.gnu.org. Although lists.gnu.org
does not yet support TLS 1.1, TLS 1.0 is better than nothing.
* lisp/erc/erc.el (erc-official-location):
* lisp/mail/emacsbug.el (report-emacs-bug):
Use https:, not http:.
|
|
Most of this change is to boilerplate commentary such as license URLs.
This change was prompted by ftp://ftp.gnu.org's going-away party,
planned for November. Change these FTP URLs to https://ftp.gnu.org
instead. Make similar changes for URLs to other organizations moving
away from FTP. Also, change HTTP to HTTPS for URLs to gnu.org and
fsf.org when this works, as this will further help defend against
man-in-the-middle attacks (for this part I omitted the MS-DOS and
MS-Windows sources and the test tarballs to keep the workload down).
HTTPS is not fully working to lists.gnu.org so I left those URLs alone
for now.

On some microbenchmarks this lets Emacs run 60% faster on my
platform (AMD Phenom II X4 910e, Fedora 25 x86-64).
* src/atimer.c: Include keyboard.h, for pending_signals.
* src/editfns.c (Fcompare_buffer_substrings):
* src/fns.c (Fnthcdr, Fmemq, Fmemql, Fassq, Frassq, Fplist_put)
(Fnconc, Fplist_member):
Set and clear immediate_quit before and after loop instead of
executing QUIT each time through the loop. This is OK for loops
that affect only locals.
* src/eval.c (process_quit_flag): Now static.
(maybe_quit): New function, containing QUIT’s old body.
* src/fns.c (rarely_quit): New function.
(Fmember, Fassoc, Frassoc, Fdelete, Fnreverse, Freverse)
(Flax_plist_get, Flax_plist_put, internal_equal, Fnconc):
Use it instead of QUIT, for
speed in tight loops that might modify non-locals.
* src/keyboard.h (pending_signals, process_pending_signals):
These belong to keyboard.c, so move them here ...
* src/lisp.h: ... from here.
(QUIT): Redefine in terms of the new maybe_quit function, which
contains this macro’s old definiens. This works well with branch
prediction on processors with return stack buffers, e.g., x86
other than the original Pentium.

* msdos/sed1v2.inp: Adapt to Emacs 25.
* src/process.c (remove_slash_colon): Move out of "#ifdef
subprocesses" block, as it its called unconditionally. Move
ADD_SUBFEATURE calls into "#ifdef subprocesses" block, as they
reference variables only defined in that block.
* src/msdos.h: Provide prototypes for IT_set_frame_parameters,
faccessat, msdos_fatal_signal, syms_of_msdos, pthread_sigmask,
dos_keysns, dos_keyread, run_msdos_command, and
syms_of_win16select, to avoid compiler warnings.
* src/msdos.c (SYS_ENVIRON): Define to either '_environ' or
'environ', depending on the DJGPP version.
Remove declarations of externally-visible Lisp objects, like
Qbackground_color and Qreverse.
(run_msdos_command): First argument is not signed, not unsigned.
Use SYS_ENVIRON.
(sys_select): Use 'timespec_cmp' instead of 'timespec_sign', as
the latter doesn't work when 'time_t' is an unsigned data type.
This caused idle timers to behave incorrectly: they only fired
after a keyboard input event.
* src/frame.c (adjust_frame_size) [MSDOS]: Account for
FRAME_TOP_MARGIN that isn't counted in the frame's number of
lines, but dos_set_window_size needs it to be added.
* src/lread.c (INFINITY, NAN) [DJGPP < 2.05]: Provide definitions.
* src/fns.c (sort_vector_copy) [__GNUC__ < 4]: Provide a prototype
that works around compilation errors with older GCC versions.
* src/w16select.c: Don't declare QCLIPBOARD and QPRIMARY as Lisp
Objects.
* src/filelock.c [MSDOS]: Ifdef away most of the code. Provide
no-op implementations for 'lock_file' and 'unlock_file'.
(Ffile_locked_p) [MSDOS]: Always return nil. This avoids multiple
ifdefs in all users of filelock.c functionality.
* src/conf_post.h (EOVERFLOW, SIZE_MAX) [DJGPP < 2.04]: Define.
* src/emacs.c [MSDOS]: Include dosfns.h, to avoid compiler
warnings.

syms_of_dosfns, and init_dosfns.
* src/deps.mk (atimer.o): Depend on msdos.h.
(emacs.o): Depend on dosfns.h.
* src/atimer.c [MSDOS]: Include msdos.h, to avoid compiler
warnings.
* lisp/window.el (window--adjust-process-windows): Skip the body
if 'process-list' is not available. This avoids failure to start
up on MS-DOS.
* lisp/vc/diff.el (diff-no-select): Test 'make-process', not
'start-process', as the latter is now available on all platforms.
* lisp/textmodes/ispell.el (ispell-async-processp): Replace
'start-process' with 'make-process' in a comment.

Work around Bug#22884 by rewording comments and strings to avoid ‘(’
at the start of a line unless it starts a function. This change
is a short-term hack; in the longer run we plan to fix cc-mode’s
performance for C files that have ‘(’ at the start of a line in a
comment or string.

Omit ‘#include "foo.h"’ unless the file needs foo.h (Bug#21707).
In a few cases, add ‘#include "foo.h"’ if the file needs foo.h
but does not include it directly. As a general rule, a source
file should include foo.h if it needs the interfaces that foo.h
defines.

* src/atimer.c (Fdebug_timer_check) [!HAVE_TIMERFD]: Actively run
the expired timers, since wait_reading_process_output doesn't.
(debug_timer_callback): Enlarge the tolerance to 20 msec.
|
|
Run admin/update-copyright.
|
|
(timerfd_callback): Ignore weird events with no data. Add tight
assertions and comments.
(init_atimer) [HAVE_TIMERFD]: Add environment variable to optionally
disabletimerfd-based timer. Use TFD_NONBLOCK for timer descriptor.
|
|
* configure.ac (HAVE_TIMERFD): Define only if TFD_CLOEXEC works,
since the code leaked file descriptors to children when !TFD_CLOEXEC.
(HAVE_TIMERFD_CLOEXEC): Remove; no longer used.
* m4/clock_time.m4 (gl_CLOCK_TIME): Don't check for clock_getres.
This reverts the previous change to this file, so it matches
gnulib again.
* src/atimer.c (TIMERFD_CREATE_FLAGS): Remove; we now assume TFD_CLOEXEC.
(alarm_timer, alarm_timer_ok, set_alarm, init_atimer):
Fall back on timer_create if timerfd_create fails at runtime.
(resolution) [HAVE_CLOCK_GETRES]: Remove; we now rely on the
kernel primitives to do resolution. All uses removed.
(timerfd) [!HAVE_TIMERFD]: Define to be -1, for convenience.
(turn_on_atimers): Clear timer_create-based timers too,
for consistency.

<http://lists.gnu.org/archive/html/emacs-devel/2014-07/msg00370.html>.
* atimer.c (timerfd_callback): Always read expiration data.
Add comment.
(turn_on_atimers) [HAVE_TIMERFD]: Disarm timerfd timer.
* process.c (add_timer_wait_descriptor): Add timer descriptor
to input_wait_mask and non_process_wait_mask as well.
|
|
* configure.ac (toplevel): Check whether GNU/Linux-specific
timerfd functions and macros are available.
* m4/clock_time.m4 (gl_CLOCK_TIME): Check for clock_getres as well.
* src/atimer.c (toplevel) [HAVE_TIMERFD]: Include sys/timerfd.h.
(toplevel): Rename alarm_timer_ok to special_timer_available.
[HAVE_TIMERFD]: Declare timerfd.
[HAVE_CLOCK_GETRES]: Declare resolution.
(start_atimer) [HAVE_CLOCK_GETRES]: Round up timestamp to
system timer resolution.
(set_alarm) [HAVE_TIMERFD]: Use timerfd_settime.
(timerfd_callback) [HAVE_TIMERFD]: New function.
(atimer_result, debug_timer_callback, Fdebug_timer_check)
[ENABLE_CHECKING]: New function for the sake of automated tests.
(init_atimer) [HAVE_TIMERFD]: Setup timerfd.
[HAVE_CLOCK_GETRES]: Likewise for system timer resolution.
[ENABLE_CHECKING]: Defsubr test function.
* src/atimer.h (timerfd_callback) [HAVE_TIMERFD]: Add prototype.
* src/lisp.h (add_timer_wait_descriptor) [HAVE_TIMERFD]: Likewise.
* src/process.c (add_timer_wait_descriptor) [HAVE_TIMERFD]: New function.
* test/automated/timer-tests.el (timer-tests-debug-timer-check): New test.

because atimer expiration is absolute rather than relative.

* atimer.c (block_atimers):
* callproc.c (block_child_signal): Block SIGINT too;
otherwise, its handler might now unblock signals that it shouldn't.
* keyboard.c (read_char): Clear signal mask, since we may
be in a SIGINT handler, and many signals may be masked.
* keyboard.c (handle_interrupt):
* sysdep.c (handle_arith_signal):
Clear signal mask instead of just unblocking the signal that
was received, since several signals may be blocked at this point.
Fixes: debbugs:17561

* atimer.c (sigmask_atimers): Remove.
Remaining use rewritten to use body of this function.
* atimer.c (block_atimers, unblock_atimers):
* callproc.c (block_child_signal, unblock_child_signal):
* sysdep.c (block_tty_out_signal, unblock_tty_out_signal):

* atimer.c (block_atimers, unblock_atimers):
* callproc.c (block_child_signal, unblock_child_signal):
* keyboard.c (handle_interrupt):
* sound.c (vox_configure, vox_close):
Restore the old signal mask rather than unilaterally clearing bits
from the mask, in case a handler is running within another
handler. All callers changed.
* lisp.h, process.c, process.h, term.c:
Adjust decls and callers to match new API.
* sysdep.c (emacs_sigaction_init): Don't worry about masking SIGFPE;
signal handlers aren't supposed to use floating point anyway.
(handle_arith_signal): Unblock just SIGFPE rather than clearing mask.

* lread.c (readevalllop_1):

* src/systime.h (make_emacs_time, invalid_emacs_time):
Don't assume struct timespec layout; POSIX doesn't guarantee it.
(EMACS_TIME_NE, EMACS_TIME_GT, EMACS_TIME_GE): Remove.

OpenBSD problem reported by Han Boetes.
* profiler.c (setup_cpu_timer): Check for failure of timer_settime
and/or setitimer.
(Fprofiler_cpu_stop): Don't assume HAVE_SETITIMER.
* syssignal.h (HAVE_ITIMERSPEC): New macro. This is for platforms
like OpenBSD, which has timer_settime but does not declare it.
OpenBSD does not define SIGEV_SIGNAL, so use that when deciding
whether to use itimerspec-related primitives. All uses of
HAVE_TIMER_SETTIME replaced with HAVE_ITIMERSPEC.
|

This should fix an OS X build problem reported by Ivan Andrus in
<http://lists.gnu.org/archive/html/emacs-devel/2012-09/msg00671.html>.
* admin/merge-gnulib (GNULIB_MODULES): Add timer-time.
* configure.ac (gl_THREADLIB): Define to empty, since Emacs
does threads its own way.
* lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate.
* m4/timer_time.m4: New file, from gnulib.
* src/atimer.c (alarm_timer, alarm_timer_ok, set_alarm, init_atimer):
Use HAVE_TIMER_SETTIME, not SIGEV_SIGNAL, to decide whether to
call timer_settime.
|
|
They avoid a race if the timer is too close to the current time.
* atimer.c (alarm_timer, alarm_timer_ok) [SIGEV_SIGNAL]: New static vars.
(set_alarm) [SIGEV_SIGNAL]: Use POSIX timers if available.
(init_atimer) [SIGEV_SIGAL]: Initialize them.
