The following test consistently fails on threaded build (and passes on non-threaded):

./perl -Ilib -Idist/Time-HiRes dist/Time-HiRes/t/clock.t
1..5
# I am the main process 52997, starting the watchdog process...
# The watchdog process 52998 launched, continuing testing...
# I am the watchdog process 52998, sleeping for 360 seconds...
ok 1 - require Time::HiRes;
# have_clock_gettime = 1
# have_clock_getres = 1
# have_clock_nanosleep = 1
# have_clock = 1
# CLOCK_REALTIME: try = 1
panic: MUTEX_LOCK (22) [HiRes.xs:773] at dist/Time-HiRes/t/clock.t line 40.
# I am the main process 52997, terminating the watchdog process 52998 before it terminates me in 360 seconds (testing took 0 seconds).
# kill KILL 52998 = 1
# All done.
# Looks like your test exited with 255 just after 1.

Upgrade Time::HiRes from version 1.9734 to 1.9739

which is confusing, since it's blead upstream.

Yes, it passes tests now.

I'm probably experiencing the same problem with 5.24.1 (on OS X 10.7), but I checked 5.25.9 after finding this thread and all the tests pass on 5.25.9. Is there any chance to backport the fix? Thank you.

Some additional information below.

Just in case here's the relevant chuck from the tests (to make sure it's the same issue?):

dist/Time-HiRes/t/clock ....................................... panic: MUTEX_LOCK (22) [HiRes.xs:773] at t/clock.t line 40.
# Looks like you planned 5 tests but ran 1.
# Looks like your test exited with 255 just after 1.
FAILED--expected 5 tests, saw 1

This might be related to:
https://rt.perl.org/Public/Bug/Display.html?id=128972

Also relevant. I'm using the following patch for 5.24, else the build would fail on Sierra:

--- dist/Time-HiRes/HiRes.xs.orig
+++ dist/Time-HiRes/HiRes.xs
@@ -940,7 +940,7 @@ BOOT:
}
# endif
#endif
-#if defined(PERL_DARWIN)
+#if defined(PERL_DARWIN) && !defined(CLOCK_REALTIME)
# ifdef USE_ITHREADS
MUTEX_INIT(&darwin_time_mutex);
# endif

It could also be that the test fails because of this patch.

From mojca.miklavec.lists@gmail.com

The tests succeed with perl5.25.9.

One of our developers says that the problem is in the included version of Time::HiRes:

v5.22.3 1.9726
v5.24.1 1.9733
v5.25.9 1.9741

Citing David:

Versions of OS X prior to Sierra do not provide the functions clock_getres(), clock_gettime(), clock_nanosleep() and consequently versions of Time::HiRes prior to 1.9729 just disabled this functionality. perl5.22 @5.22.3 has 1.9726 so passes the test.

Time::HiRes 1.9729 then implemented emulation of clock_getres(), clock_gettime(), clock_nanosleep() on OS X platforms as an enhancement

Sierra however introduced clock_getres(), clock_gettime() but not clock_nanosleep() which broke the 1.9729 emulation code. This was fixed in Time::HiRes 1.9739 but perl5.24 @5.24.1 has 1.9733 so fails on Sierra.

perl5.25 @5.25.9 has 1.9741 with this Sierra fix (and a few others for Sierra and El Capitan) so passes the test.

Yeah, this does sound like a sensible thing to backport.

I agree.
