[Koha-devel] Deadlock issues when running the tests in parallel, and maybe not only in the tests?

[Victor Grousset/tuxayo]

Hi :)

IIUC this is where the CI calls "prove" to run the tests
https://gitlab.com/koha-community/koha-testing-docker/-/blob/master/files/run.sh#L213

And this is the place where KOHA_PROVE_CPUS is set.
https://gitlab.com/koha-community/koha-testing-docker/-/blob/master/files/run.sh#L155
It's not set in ".env" file so it should use "nproc" and this calls 
"prove" with more than one thread.

Is that really the case? I tried locally use to "prove -j 4" and I'm 
getting deadlocks with the database after a few minutes.

And do these deadlock in tests mean that Koha can hit them while running 
in production?

I expect the tests to fail due to messing up with each other data but a 
deadlock is something else.


Cheers,
