Hmm, looks like the test is failing on master as well. Looks like it's benjaminp/six#352

this comment has been orphaned

That comment is still relevant in its current place! L690-L720 is figuring out the "after any docstrings and __future__ imports part".

it's 40 lines away from the code that's relevant to the comment (the "special imports")

Okay, made a change! :-)

asottile

It currently breaks all builds and even after pytest-dev#8540 it looks like tests still fail because of benjaminp/six#341 As a hotfix, mark it as experimental until everything is fixed, so that our CI isn't all red.

Could someone elaborate on how I can actually reproduce this? I'm trying to fix the testsuite on Python 3.10, but I don't see this issue happening at all.

Could someone elaborate on how I can actually reproduce this? I'm trying to fix the testsuite on Python 3.10, but I don't see this issue happening at all.

for example: https://github.com/asottile/flake8-match

git clone [email protected]:asottile/flake8-match
sudo add-apt-repository ppa:deadsnakes/nightly
sudo apt install python3.10-dev
tox -e py310

The-Compiler · 2021-04-14T14:59:04Z

Ah, I see - I was running 3.10.0a7 (because that's what @Zac-HD mentioned in the issue), but this is actually a very recent change. I can reproduce it when installing python3.10-dev via pyenv, which gives me "Python 3.10.0a7+ (heads/master:d9ba9de, Apr 14 2021, 16:49:31)".

This also explains why this isn't needed on CI - it will be once beta 1 is out.

nicoddemus

Thanks a lot @hauntsaninja!

nicoddemus · 2021-04-15T11:56:07Z

Should have squashed, my bad! 🤦‍♂️

hroncok · 2021-04-15T11:59:39Z

Will this not break actual alpha 7?

nicoddemus · 2021-04-15T12:02:00Z

Hmm I suppose, good point. Should we revert this and wait for beta 1?

hroncok · 2021-04-15T12:08:45Z

I think we can make the version check more specific.

hroncok · 2021-04-15T12:14:03Z

I cannot trigger a problem on Python 3.10.0a7, so maybe this is fine.

The-Compiler · 2021-04-19T09:42:39Z

FYI, GitHub Actions seems to have pushed a rather weird "beta 1" release which isn't actually beta 1 - so if we're seeing an influx of new reports about this, that'd be why (as python: 3.10-dev now uses that affected release rather than Alpha 7).

@AlirezaTheH please open a new issue with a reproduction

@parsanoori as seen in the output header, you're actually running pytest 6.2.2 in the virtualenv there.

parsanoori · 2022-07-23T09:17:32Z

It's the git maintainer's problem.
Thanks.
