tests/middleware/test_logging.py::test_running_log_using_fd fails on PyPy3.9 7.3.9

[mgorny]

When running the test suite in the 0.20.0 release using:

$ pypy3 --version
Python 3.9.12 (05fbe3aa5b0845e6c37239768aa455451aa5faba, Oct 10 2022, 09:02:36)
[PyPy 7.3.9 with GCC 11.3.0]

I'm getting the following test failure:

The same version passes all tests on CPython versions with the same dependencies, so I think this is PyPy-specific problem. I suspect some API may be missing that is used to determine on what socket it is running. If you tell me what's missing, I can pass the bug on to PyPy developers.

What OS is that?

[mgorny]

Ah, sorry. It's Gentoo Linux/amd64.

[Kludex]

Does it fail on other pypy versions or only 3.9?

[mgorny]

I don't know. I'm unable to install working dependencies for uvicorn in a venv, so I can only test using installed Gentoo packages, and Gentoo only supplies PyPy3.9.

[Kludex]

Why are you unable to install them? 🤔

That's what I get when trying to run tests.
