Obviously relative CLOCK_REALTIME waits should not be be affected if the time changes because it's been set wrong. But that's a different matter from changing it because real time has elapsed without it noticing. Posix was not really written with modern systems in mind.

POSIX states that: "Setting the value of the CLOCK_REALTIME clock via clock_set=E2=80=90 time(2) shall have no effect on threads that are blocked waiting for a relative time service based upon this clock" So I'm guessing that Linux is just using CLOCK_MONOTONIC for consistency so that nanosleep() behaves the same, whether or not CLOCK_REALTIME jumps due to suspend/resume or settime(). If other system's nanosleep() are dependent on settime() then that seems in contravention of POSIX. If other system's nanosleep() are dependent on suspend/resume then that seems inconsistent. It seems like we need to specify a TIMER_ABSTIME via clock_nanosleep() or timer_settime() to both provide that behavior as an option and possibly reduce inconsistency between systems. cheers, P=C3=A1draig.

But that's not what 'sleep' does, on systems where 'nanosleep' uses real time, which is what POSIX specifies. The Linux kernel uses CLOCK_MONOTONIC for nanosleep, as opposed to the POSIX-specified CLOCK_REALTIME. This is an infelicity.

I agree that either behavior could be required.
The default though should probably stay as is.
I.E. when the system suspends, the timeout suspends too.
Changing to "wall clock time" would require an option,
as that can jump around due to suspend, ntp, ...
We had this discussion recently also, in relation to timeout(1).
timeout(1) currently uses timer_create(CLOCK_REALTIME).
According to docs=C2=B9, that should jump due to settime()/settimeofday()=
/resume
though I can't reproduce here with a resume, or even when pushing the
updated system clock down to the hardware:
# timeout 3 sh -c 'date --set=3D$(LC_ALL=3DC date -d 10\ sec +@%s); hwclo=
ck -w; sleep 1'
# echo $?
0
Here is some pertinent info from nanosleep(2) (used by sleep(1)):
POSIX.1 specifies that nanosleep() should measure time against th=
e
CLOCK_REALTIME clock. However, Linux measures the time using th=
e
CLOCK_MONOTONIC clock. This probably does not matter, since th=
e
POSIX.1 specification for clock_settime(2) says that discontinuou=
s
changes in CLOCK_REALTIME should not affect nanosleep():
Setting the value of the CLOCK_REALTIME clock via clock_set=E2=
=80=90
time(2) shall have no effect on threads that are blocked waiting
for a relative time service based upon this clock, including the
nanosleep() function; ... Consequently, these time services
shall expire when the requested relative interval elapses, inde=E2=
=80=90
pendently of the new or old value of the clock.
Maybe the kernel is incorrectly implementing this POSIX clause
for our interval timer. Perhaps we need to specify TIMER_ABSTIME
to timer_settime to avoid that? I need to look into that further.
Anyway to explicitly select with an option, a "running time" rather than
"wall time" we could use CLOCK_MONOTONIC (or CLOCK_MONOTONIC_RAW on newer=
kernels).
That's not always available though, so then we'd have to look at/document
the inconsistency on systems without CLOCK_MONOTONIC.
Note also that timeout currently doesn't handle a SIGSTOP or SIGTSTP spec=
ially,
as I was thinking it should count down system running time rather
than job running time, as that is dependent on many factors.
cheers,
P=C3=A1draig.

In fact, I think both modes have their use, and that we probably ought to provide an option to choose between absolute wall clock deadline (stable realtime sleep even if the processor time jumps forwards or backwards or has gaps due to suspend) vs. elapsed relative processor time (where changing the processor clock can lengthen or shorten the sleep duration). If we do add code to support multiple flavors of sleep durations, I'd probably lean towards absolute wall time as the default. --=20 Eric Blake eblake@HIDDEN +1-919-301-3266 Libvirt virtualization library http://libvirt.org --------------enig870CA67E7C76E8C8A68FB28D Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) Comment: Public key at http://people.redhat.com/eblake/eblake.gpg Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iQEcBAEBCAAGBQJQM/eTAAoJEKeha0olJ0NqlLEH/31lL2yuJs+retonIi0hBGL6 fHl0siuk+4QvfT6RVbMBUDl3RTHFzW+zerSrG/eeuQKU84b8kpXfIA96ODk+J0gD McIMqEYpHhmeutR008GGE1KEcH+2qE5Die3+ZHsQ3COdXfksIQ1yo6Dbx8aQZxWE BImb0dwEaRNBb1Lzf4YHOBc+NnBVlwUMP2SY6j2/RqgAZ1DLCWmR8N2jN+mCPYPn nHf+8WYyFypfnUQXyQ9++oyvq4x3djorA+/uRZYAmUXPF+KAFcEZ2ExCQLiQcP5E 5QfF3OWeE6VfAfQvCkGirPee1k4aWcYvTmqAHVB4Eo3Yy9wUKJLhWRfD5gARZaE= =64f9 -----END PGP SIGNATURE----- --------------enig870CA67E7C76E8C8A68FB28D--

Sleep has always been a pause in relative time from when the call is made to when it returns. Implementations have varied (signals, select, etc.) each with various issues causing a move from one to the other method. But if the system suspends then all processes suspend together. When the system wakes up then all processes proceed together from the point where they left off when suspending. I think anything else is going to create a lot of problems. I could see a big problem for many processes on the system if when the system resumes from suspend that all of the sleeping processes "all go off at once". It would cause a huge spike in system load as all of them fired all at one time. Granted that most sleeping processes are going to be sleeping in C code and no change to the coreutils sleep program will affect them. But any scripts that are using sleep would be affected. Also, the reason for sleep is often to add skew between two events. If upon wakeup all of the sleeping processes are all triggered then all relative skew will have been removed. Worse the wakeup would act as a synchronization point causing all of the sleeping processes to be deskewed. But I can definitely see that sleeping until a particular time would be useful behavior. But that would be such as large expansion of code and behavior that I think it should warrant a different program rather than expand sleep that much. Should we create a new command that sleeps until a particular system time? sleepuntil --date="now + 30 minutes" Bob
