Hi

In https://github.com/pypa/pipenv/pull/5343#issuecomment-1241083067 you mentioned:

This will need to wait until pytest v7.2.0 pytest-dev/pytest#9982

pytest 7.2.0 has now been released: https://github.com/pytest-dev/pytest/releases/tag/7.2.0

Also, Python 3.11.0 was released last night, and testing locally with pipenv 2022.10.12, I get the following RuntimeWarning:

       .../lib/python3.11/site-packages/pipenv/vendor/attr/_make.py:876: RuntimeWarning: Running interpreter doesn't sufficiently support code object introspection.  Some features like bare super() or accessing __class__ will not work with slotted classes.
         set_closure_cell(cell, cls)

This is coming from the attr package, which was fixed in v22.1.0 (https://github.com/python-attrs/attrs/commit/a18b3957d55c669de56799a9a72ea31febe93ce4) however pipenv is still using v21.2.0: https://github.com/pypa/pipenv/blob/v2022.10.12/pipenv/vendor/vendor.txt#L2

As such, attr will need bumping too, as well as pytest.

Thanks, Ed

• [x] vendor.txt: Upgrade to attrs==22.1.0
• [ ] Where is the version of pytest specified?

[edmorley]

For attr, I believe the vendored copy also needs updating by running the command mentioned here: https://github.com/pypa/pipenv/blob/main/pipenv/vendor/README.md

Where is the version of pytest specified?

I'm guessing it's maybe pulled in implicitly via one of the pytest-* deps here? https://github.com/pypa/pipenv/blob/cb9d87ad05830449743cbc3ffa09ebbc7cca602d/Pipfile#L6-L21

Maybe refreshing this repo's Pipfile.lock will be sufficient to pick up the 7.2.0 update?

[edmorley]

@cclauss Several vendored dependencies (including attr) have now been updated on main. Could you rebase on main to pick up those changes? After that, I would recommend running pipenv lock to refresh this repo's Pipfile.lock, since hopefully the pytest update will resolve the other issues :-)

@oz123 HI! I don't suppose you have a spare moment to review/merge this? :-)
