The aim of this series is to add pthread_clockjoin_np, which works
like pthread_timedjoin_np except it accepts an additional parameter to
indicate which clock the timeout should be measured against.
The naming matches the pthread_cond_clockwait,
pthread_mutex_clocklock, sem_clockwait, etc. functions added in glibc
v2.30 and documented at http://austingroupbugs.net/view.php?id=1216.
The series also includes some minimal documentation for
pthread_tryjoin_np and pthread_timedjoin_np, along with some new
tests.
Thanks to everyone who provided feedback for the first version[1] of
this series.

This documentation isn't perfect, but it's better than nothing and can
hopefully act as a basis for future improvement. In particular, although
I'm certain that the functions are MT-Safe, I'm not sure about the rest of
the @safety line.
Yann Droneaud pointed out that pthread_timedjoin_np would wait forever if
the timeout parameter is passed as NULL. Since it's now too late to change
that, I've documented it.

Introduce pthread_clockjoin_np as a version of pthread_timedjoin_np that
accepts a clockid_t parameter to indicate which clock the timeout should be
measured against. This mirrors the recently-added POSIX-proposed "clock"
wait functions.
* NEWS: Mention addition of pthread_clockjoin_np along with other
"clock" variants of existing "timed" functions.
* sysdeps/nptl/pthread.h: Add declaration of pthread_clockjoin_np.
* manual/threads.texi: Add pthread_clockjoin_np.
* nptl/Makefile: Add pthread_clockjoin source file. Add new join
tests.
* nptl/Versions: Add pthread_clockjoin_np.
* nptl/PthreadP.h: Rename __pthread_timedjoin_ex to
__pthread_clockjoin_ex and add clockid_t parameter.
* nptl/pthread_clockjoin.c: New file to implement pthread_clockjoin_np.
* nptl/pthread_join_common.c (clockwait_tid): Rename from
timedwait_tid and add clockid parameter. Use __clock_gettime
passing supplied clockid rather than using __gettimeofday. Perform
relative timeout calculation entirely in timespec.
(__pthread_clockjoin_ex): Rename from __pthread_timedjoin_ex and
add clockid parameter to pass to clockwait_tid rather than
timedwait_tid.
* nptl/pthread_timedjoin.c (__pthread_timedjoin_np): Call
__pthread_clockjoin_ex passing CLOCK_REALTIME as clockid.
* nptl/pthread_join.c (__pthread_join): Call __pthread_clockjoin_ex
and pass zero as unused clockid_t parameter.
* nptl/pthread_tryjoin.c (__pthread_tryjoin_np): Likewise.
* nptl/thrd_join.c (thrd_join): Likewise.
* nptl/tst-join3.c (tf): Ensure that mutex is unlocked after use so
that it can be used again. (do_test_clock): Rename from do_test and
accept a clock parameter. (do_test): Test pthread_timedjoin_np,
pthread_clockjoin_np with CLOCK_REALTIME and pthread_clockjoin_np
with CLOCK_MONOTONIC.
* nptl/tst-join5.c (thread_join): Add support for testing
pthread_clockjoin_np with both CLOCK_REALTIME and CLOCK_MONOTONIC.
* nptl/tst-join10.c: Wrap tst-join5.c with
USE_PTHREAD_CLOCKJOIN_NP_REALTIME.
* nptl/tst-join11.c: Wrap tst-join5.c with
USE_PTHREAD_CLOCKJOIN_NP_REALTIME and WAIT_IN_CHILD.
* nptl/tst-join12.c: Wrap tst-join5.c with
USE_PTHREAD_CLOCKJOIN_NP_MONOTONIC.
* nptl/tst-join13.c: Wrap tst-join5.c with
USE_PTHREAD_CLOCKJOIN_NP_MONOTONIC and WAIT_IN_CHILD.

To: libc-alpha; +Cc: Mike Crowe
Passing NULL as the timeout parameter to pthread_timedjoin_np has resulted
in it behaving like pthread_join for a long time. Since that is now the
documented behaviour, we ought to test that both it and the new
pthread_clockjoin_np support it.
* nptl/tst-join14.c: Test passing NULL as abstime parameter of
pthread_timedjoin_np and pthread_clockjoin_np.
* nptl/Makefile: Add tst-join14.c.

To which semantic do you think it would be better to change? Since this
symbol are not yet in POSIX there still the possibility to change it
by using a new plus a compat symbol.

I see the addition begin reasonable now that we are also providing similar
functions for mutexes, conditional variables, read-write locks, and
semaphores.

I think it's the behavior we want in order to accomodate for every
needs with a single interface:
- wait forever (aka. pthread_join()) : pass NULL
- wait: (aka. pthread_timedjoin_np()): pass deadline
- don't wait (aka. pthread_tryjoin_np()) : pass current time
The later could be made more usuable if (struct timespec){ 0, 0 } would
have a special meaning, but it cannot, as timestamp can overflow ...

The alternative would be to mark the timeout parameter as __nonnull and not
permit it to be NULL, as is the case for the other pthread timed*/clock*
functions. I imagine that if the functions were ever standardised then this
would be the case - but that doesn't look like it's on the horizon.
Although we wouldn't break existing binaries if we change the behaviour and
add a compat symbol, we could break people compiling existing source. I
don't think it's a serious enough problem for it to be worth even doing
that.
However, if others feel strongly about it then I'm prepared to make that
change.
Thanks.
Mike.

Do you mean that I should unlock the mutex after the loop inside
do_test_clock? If so, that would mean unlocking it on a different thread
and that doesn't sound like it's guaranteed to be safe.
Or perhaps you meant something different?
(The use of a mutex for this test works, but it's non-obvious. Perhaps a
semaphore would be clearer?)
Thanks for the rest of the review. I will make the changes you describe.
Mike.

This needs to call pthread_clockjoin_np if clockid indicates so, as below.

At least other pthread interfaces that uses a timespec as input argument
add a nonnull on their interfaces. However they handle a null not equal:
- pthread_mutex_{clock,timed}lock will trigger a SEGFAULT due
lll_timedlock_wait.c:31 for the contended case, it works for
uncontended case (where an userspace atomic operation is suffice).
- pthread_cond_timedwait will also trigger a SEGFAULT due
nptl/pthread_cond_wait.c:648.
- pthread_{rw,rd}lock_{clock,timed}lock will handle it as unbounded
time (since both pthread_rwlock_common.c and futexes call check if
abstime is NULL).

I don't see that making pthread_timedjoin_np behaves differently than
other pthread interfaces a good move forward. So I would avoid support
both 'wait forever' and 'don't wait' semantic in this case.
And POSIX also is not specific regarding timeout handling in aforementioned
pthread interfaces. And systems that implement them do differ, for instance:
- FreeBSD 11.1 does not trigger any build warning or runtime error for
NULL argument for neither pthread_mutex_timedlock or
pthread_{rw,rd}lock_lock. The pthread_cond_timedwait does return
EINVAL though.
- Solaris 11.4 seems to behave as glibc, it triggers a SEGFAULT for
pthread_mutex_timedlock (for *both* contended and non-contended case),
pthread_{rw,rd}lock_timedlock, *and* for pthread_cond_timedwait.
- AIX 7.2 returns EINVAL for contended pthread_mutex_timedlock case and
works for non-contended case. It does not trigger any runtime issue
for {rw,rd}lock and also returns EINVAL for pthread_cond_timedwait.
So trying to come up with a portable error handling does not seem to
that valuable, it leads to believe common usage is to *not* use NULL
value for timeout arguments.
So I would suggest to sync with current practice and fail early for
invalid inputs either by EINVAL or by assuming valid pointer (which
trigger an invalid memory access and warns user that this is an invalid
usage).

Yeah, but it is not really a strong opinion. It just make the patch
change less code in the original test.

Since pthread_timedjoin_np is not new, we risk changing the behaviour of
existing code that may have come to rely on the behaviour when passing
NULL. Even if we use symbol versioning to ensure that code compiled against
old glibc continues to behave as it always did, we still risk changing the
behaviour when code is compiled against the newer glibc. If that code is
compiled with -Wnonnull and the compiler is able to determine that NULL is
being passed (which it may not if the code in question is using a wrapper
function) then a warning would be emitted which may help, but does not
guarantee that the change will be noticed.
pthread_clockjoin_np is new, so it doesn't have any legacy behaviour. We
can mark the timeout as __nonnull. We could check the argument against NULL
and return EINVAL, but it seems that the compiler warns when checking
__nonnull arguments and just throws the check away[1] so we're probably
stuck with potentially faulting in that situation.
In my view, changing the behaviour of pthread_timedjoin_np now is of little
benefit compared to the risk of breaking existing code. That ship has
sailed. Having decided that, I thought that making pthread_clockjoin_np
behave differently to pthread_timedjoin_np would be confusing, so I settled
on it behaving the same way.
So, what are you proposing we should do? Change the behaviour of the
existing pthread_timedjoin_np function and the new pthread_clockjoin_np
function or only of the latter?
Thanks.
Mike.

At least for code built against a new symbol we can not only add the nonnull
but at result EINVAL for invalid abstime. It would be semantic change, but
it is what compat symbol are used mainly.

I agree with your rationale that we should not change pthread_timedjoin_np
and mimic its behaviour for pthread_clockjoin_np (in fact I acked the patches
already).
This discussion was mostly due the proposition Yann Droneaud brought to you
and you mentioned in the email. I think the patchset is good to be pushed
upstream.

Hi Mike,
I think your patchset it ready to push upstream. I have fixed the small
nits I brought on the review along with some more specific changes below:
- Move the NEWS entry for pthread_clockjoin_np to its own bullet on
2.31.
- Moved __pthread_clockjoin_ex to a hidden definition and removed the
hidden_{proto,def}.
- Added some missing one line file description.
I also pushed the set on a personal branch [1]. If you are ok with this
set, I would like to push it upstream.

Hi Adhemerval,
Thanks for doing all that. I thought that I'd addressed the nits, but I
must have missed or lost some. :(
Your branch looks great, except it appears to be missing this hunk from the
"nptl: Add pthread_clockjoin_np" change:
diff --git a/nptl/tst-join3.c b/nptl/tst-join3.c
index c06e65a247..faf7683eaa 100644
--- a/nptl/tst-join3.c
+++ b/nptl/tst-join3.c
@@ -56,7 +56,12 @@ do_test_clock (clockid_t clockid)
struct timespec timeout = timespec_add (xclock_now (clockid_for_get),
make_timespec (0, 200000000));
- int val = pthread_timedjoin_np (th, &status, &timeout);
+ int val;
+ if (clockid == CLOCK_USE_TIMEDJOIN)
+ val = pthread_timedjoin_np (th, &status, &timeout);
+ else
+ val = pthread_clockjoin_np (th, &status, clockid, &timeout);
+
TEST_COMPARE (val, ETIMEDOUT);
xpthread_mutex_unlock (&lock);
I suspect that it's not causing the test to fail because the existing call
to pthread_timedjoin_np will just time out immediately if passed the
relatively small absolute CLOCK_MONOTONIC time. I shall see if I can
improve this test to catch that in the future.
Thanks again.
Mike.

Right, I have updated my personal branch with the missing change, thanks
for spotting it.

These changes introduce a testsuite build failure for hppa because they
fail to update the separate hppa pthread.h.

I've posted a patch that fixes this, and the hppa-specific
pthread.h change at
https://sourceware.org/ml/libc-alpha/2019-11/msg00020.html .
Thanks for reviewing this.
Mike.
