Can you please elaborate?

[nineteendo]

Same issue as here: #120660 (comment). test_interpreters isn't skipped properly:

1 test run no tests: test_interpreters 

This is distracting when reading through the logs and the same change you asked me to make (mine didn't even work).

LGTM

FWIW, the skipping should be removed in the near future. (See #117953 (comment).) However, fixing this in the meantime makes sense.

[vstinner]

Should the change be backported to the 3.13 branch?

[vstinner]

Merged, thanks.

[ericsnowcurrently]

gh-118157 was merged before the feature freeze, thus it is part of the 3.13 branch. Backporting this would make sense.

GH-120707 is a backport of this pull request to the 3.13 branch.

[nineteendo]

Hmm, should we include the version in the title of all pull requests? [3.14] gh-117953: Skip `test_interpreters` properly without GIL. That would make it easier to determine in which version something was added.

[ericsnowcurrently]

I'm not sure it would be worth it. The time interval in which there's any uncertainty is relatively small and the target version for a PR against main can shift depending on how long its open. It isn't too hard to see if a commit (from a PR) is included in a specific release branch (or tag).

[nineteendo]

OK, probably not worth it. I just feel bad for making a mistake because of it.

[ericsnowcurrently]

There's nothing to feel bad about! We figured it out pretty quickly and even if we hadn't, it wouldn't have been a big deal.
