[ovirt-devel] [VDSM] stuck tests in the ci - update

Hi all,

So we have this patch, aborting stuck tests and printing a backtrace
of all threads:
https://gerrit.ovirt.org/#/c/58212

On fedora, we get now a nice backtrace (see bellow) - which show that
we have unexpected
threads running during the tests.

we have 25 iopproces threads like this:

This is expected given the current code managing these, and are daemon threads.

We have 8 reactor threads:

I don't know where these are started and it they are daemon threads.

Searching the tests, we have too much code creating threads directly,
instead of using vdsm.concurrent.thread:

$ git grep Thread tests/ | wc -l
79

Please check your tests, and replace all threads to use testlib.start_thread()
creating daemon threads.

Code inheriting from threading.Thread is the worst, please keep a thread
instance instead, and start it with testlib.start_thread().

I sent this patch fixing sslTests for now:
