creating/binding a socket in a fixture causes it to not close
altendky opened this issue · 6 comments

Describe the bug
While creating and binding a socket in a test and then closing it allows the same port to be reopened later in the test, if the socket was originally created and bound in a fixture then it fails claiming OSError: [Errno 98] Address already in use.

I expect sockets created and bound in a fixture to be able to be closed.
Desktop (please complete the following information):
- OS: Linux (Ubuntu 20.04.3 LTS)

- Pytest version: 6.2.5
- pytest-monitor version: 1.6.3
Additional context
I probably won't get to it tonight, but I will try to see what I can learn about pytest-monitor towards the end of fixing this. I tested back to pytest-monitor v1.0.0 and it seems to be present throughout.

Hello @altendky
Thanks for the time spent on this. However, I am unsure to get it right.
You already bind your socket in your fixture and try to rebind it in your test. In your fixture, the where will be evaluated to 'fixture' and is then returned to the stack in your test. Thus, you bind twice the same object.
Additionally, you probably want to close your socket after the yield statement in your fixture.
Please correct me if I misunderstood your problem.
altendky commented
Before rebinding to the port, in either case, the first socket is closed. Looking at the pytest output in the full session it shows that the second parametrization where the socket is created in the test there is no error (be sure to expand the collapsed sections in the OP and below here). Closing the socket in the fixture during teardown would normally make sense, but it isn't relevant to this example since it would occur after the error. Note that the failing test with the socket from the fixture is run first so it can't be caused by an issue not closing the socket from the passing case which is second.
I probably shouldn't have parametrized the tests. Here's a more explicit non-parametrized recreation.

Forcing it to run wrapped_function() instead of prof() seems to avoid the problem. So, perhaps I need to bump this over there. I'll see if I can make a recreation just using memory_profiler.memory_usage().

It does appear to be down in memory_profiler (or below?). pythonprofilers/memory_profiler#342 I would personally leave this open until it is resolved so it is easy to find if anyone else runs into this. But, at the moment, it doesn't look like there's any action needed on your part in terms of fixing this.

Ok got your point.
My intuition drives me to memory_profiler at first glance since the profiling launches a monitoring process apart. I'll check this out next week...

Already filed a bug there since I could recreate with just it. Link above. I'll follow up there if I manage any more debugging.
