Hi All,
We have suddenly encountered a hung git-http-backend in t5562 in the NonStop
port. This is a new problem not seen before on the platform, surprisingly. I
am wondering whether this is a result of not actually having an apache2
server on-board. Is that a possibility and can that sub-test be bypassed if
no apache2 is detected?
We also had subtest 15 and I am investigating, but it may depend on 8's data
(I had to kill the git-http-backend process, so maybe that's why).
Thanks,
Randall

I'm back to investigating subtest 8 hanging after dealing with the /dev/zero
thing. What we end up with two git processes, a git-http-backend, a perl,
and a few shell processes. The act.err file had:
fatal: request ended in the middle of the gzip stream
Which went through die() and should have unwound the whole thing, but
didn't. The git-http-backend is waiting to clean up children and each git is
polling for input. It seems like SIGCHLD did not get back through the
process that started it, or its parent - but I don't quite follow the flow
in this test. I have seen the perl port not like SIGCHLD sometimes, so that
might be what is going on. Is it possible to skip the hanging subtest during
a whole test run? We don't really have anyone using the http backend on
platform (SSH is the generally preferred method to get to git on box), so I
am tempted to ignore the ones that hang as conditional known breakages, if
that is possible, so that we can get our CI builds back in operation.
Thoughts? Advice?
Thanks,
Randall
