Pytest django crashing with pyest 8.0.0

[jacobowitz]

We seem to have an issue in our test setup with pytest-django and the new 8.0.0 release of pytest. Just pinning pytest to the last 7.x version is a working workaround for us.

Our database setup fixture is crashing since the new pytest version was released. I am not sure which component is ultimately responsible for this bug, but I figured I could try pinging you first as it might be very well in pytest-django.

This is the error we are getting. It looks like it is trying to setup the db to often and thus generates too long database names as a side effect.

Begin of the stack trace

pytest_django/fixtures.py:305: in handle shows up 293 times in total. Looks like some kind of recursive loop

Can you show your pytest configuration and how you invoke pytest?

Also, does it still happen if you disable parallelism (i.e. run without using -n auto or such)?

We also see this sometimes after upgrading to pytest 8.0.0.

Debugged a bit and noticed after running tests for some time at a certain time in pytest-django in method django_db_modify_db_settings_xdist_suffix the value of the test database name seems wrong.

I see these values:

suffix = 'gw2'
test_name = 'test_gw2'

This means after the method returns the database name will be test_gw2_gw2.

I will try to reproduce with pytest 8.0.2 also.
