Occasional `pytest_internalerror() was called on the worker` error #153

Open rouge8 opened 2 years ago

rouge8 commented 2 years ago

We're seeing our test suite occasionally fail to start with pytest_internalerror() was called on the worker:

I don't have a good reproducer and it's intermittent.

Running Python 3.10.6 I believe.

So I think that ValueError: signal only works in main thread of the main interpreter is the actually 'interesting' error here. It's funny because lately I've been dealing with this funny business with pytest-xdist myself. I guess if we're in an xdist process then pytest-twisted could choose to not bother with the signals. Though that code was added to avoid twisted taking control of SIGINT so that pytest stuff could handle it as it wishes. But, if it isn't going to work anyways... I guess maybe we're ok.

https://github.com/pytest-dev/pytest-xdist/issues/620 describes a similar issue with a link to https://github.com/pytest-dev/execnet/issues/96. I commented at 620 so let's see what they say there before we hack around this.

altendky commented 2 years ago

Could you try out #154? I think we may also need to tell Twisted to not configure the signals. You should be able to install it directly such as venv/bin/pip install 'pytest-twisted @ https://github.com/pytest-dev/pytest-twisted@only_set_signals_in_main_thread.

Hmm, #154 failed on my first run (but looks like it's fine on the second):

That traceback doesn't agree with the line numbers of the present code in the branch.

Anyways, run it for a bit and let me know how it goes. Pending no issues we can merge etc.

D'oh, it didn't replace the existing pytest-twisted install because the version numbers were the same 🥲. Fixed! I'm not sure of a great way to test it -- I guess I'll try running a subset of our test suite a couple hundred times and see if it errors.

I am sometimes seeing

gw0 ok / gw1 ok / gw2 ok / gw3 ok / gw4 ok / gw5 ok / gw6 C / gw7 ok/Users/andyfreeland/src/pilot/zapgram/.ve/lib/python3.10/site-packages/pytest_twisted.py:205: RuntimeWarning: Failed to block Twisted signal configuration due to not running in the main thread. See https://github.com/pytest-dev/pytest-twisted/issues/153.

I ran it 100 times, got the runtime warning ~25 times, but no crashes!

altendky commented 2 years ago

Thanks. That is an intentional warning. pytest can be set to ignore specific warnings in case you like to make all warnings errors. But, this is a situation that nobody anywhere seems to want to have happening so it seemed reasonable to add the warning. That does confirm though that twisted itself doesn't end up failing out in that scenario, so that is good. I'll plan to get this merged soon. Thanks again for the report and for the testing.

I didn’t notice you merged #154 a couple weeks ago; any plans for a new release?

altendky commented 1 year ago

Should be released in https://pypi.org/project/pytest-twisted/1.14.0/. Sorry for the wait and thanks for the patience.

Thanks!!
