test_gevent is failing

[int19h]

Due to warning for deprecated usage of pkg_resources in more recent versions of setuptools.

Fixed by #1374

Hi @int19h! It looks like we're still having this problem in python versions older than 3.7 in nixpkgs. Was just wondering if you had any insight for why it'd still be failing: NixOS/nixpkgs#255379 (review).

Adding importlib-metadata as a test dependency doesn't seem to make a difference.

[int19h]

importlib-metadata is really only used for logging. The problem with gevent is a different issue - it's due to an incompatibility between gevent and newer versions of setuptools. You have to use setuptools<66 to fix it.

Also note that any version of debugpy >=1.6.0 doesn't support versions of Python older than 3.7, and debugpy>=1.8.0 requires python>=3.8.

Oh yep!! We've marked python 3.8 as the minimum compatible python version in the 1.8.0 update.

We were just seeing this deprecation warning in newer versions of python too. From what I can tell, it looks like the setuptools<66 workaround was only being used for python 3.7?

[int19h]

Yep, that's the only version for which it showed up in our CI runs. Although I believe the problem there wasn't actually with Python itself, but rather with setuptools version that is bundled with it; if it's too old, it ends up being updated to the most recent version as a transitive dependency of something else (IIRC, tox itself), causing the problem.

Oh ok that makes sense! In nixpkgs, we package setuptools ourselves, so it would generally always be the latest version (even with older python versions). Thanks!! 😊
