Upgrade to setuptools 67.6.1 causes `DeprecationWarning` about `pkg_resources` #11975

robsdedude · 2023-04-17T16:04:01Z

Description

d7e0248 bumped setuptools introducing a deprecation warning "pkg_resources is deprecated as an API".

I don't see a way of making pip not run into it. With env variable _PIP_USE_IMPORTLIB_METADATA set, trying to install something with pip, I get

DeprecationWarning: pkg_resources is deprecated as an API

Expected behavior

I'd like there to be a way to invoke pip such that it does not emit any warnings (unless of course some package relies on legacy setup methods or other valid warning cases).

That way, I can run pip with warnings as errors in my CI and actually notice when I run into deprecations.

pip version

23.1

Python version

3.10.10

OS

Linux

How to Reproduce

Install pip 23.1
python -m install pip==23.1
Run it with warnings as error
python -W error -m pip freeze
💥

Output

No response

_PIP_USE_IMPORTLIB_METADATA avoids most use of pkg_resources, but it looks like we still use it to find .egg distributions, even in the importlib.metadata code path.

Maybe we should just stop supporting eggs? IMO, it's about time.

In the meantime, I don't know what the best course of action is - we could patch out the warning from our vendored copy of setuptools, or disable the warning using the warnings machinery. Or we could just revert the setuptools upgrade, as being more trouble than it's worth... @pypa/pip-committers any thoughts?

I should point out, this might block the backport of 23.1 to ensurepip in CPython 3.10 and earlier¹, as I believe the CPython test suite runs with warnings as errors.

I've created the PR for CPython, but not merged it yet as I wanted to wait in case we needed a 23.1.1... ↩

Let's do that, for now.

pfmoore · 2023-04-17T16:51:40Z

Let's do that, for now.

#11976

I won't merge just yet, I'll wait in case any other committers have different views.

I don't think this means that we should remove the setuptools upgrade from the ensurepip PR for CPython, as it's only used to pre-install in venv.

sbidoul · 2023-04-17T16:56:22Z

Should we enable the egg deprecation at the same time?

               yield dist

pfmoore · 2023-04-17T17:01:33Z

I'm -1 on doing that in a bugfix release. Maybe we should have done it in 23.1, but we didn't...

pradyunsg · 2023-04-17T18:09:37Z

Oh, I think we should -- python/cpython#101039 ;)

pfmoore · 2023-04-17T19:06:16Z

If that goes in, then yes I'll drop setuptools from the upgrade PR. The current iteration of that PR is on the basis that the removal is stalled while the test suite issues get fixed (and so I'd rather we had the latest setuptools version in the meantime).

pradyunsg · 2023-04-17T19:35:39Z

Oh, the test suite was fixed in a separate PR. :)

pfmoore · 2023-04-17T19:39:25Z

Cool, I'll update the PR when python/cpython#101039 gets merged (I'd have to anyway as my PR would get merge conflicts 🙂)

uranusjr · 2023-04-18T00:58:30Z

So what should we move forward with this? It seems like a bad idea for us to suddenly deprecate eggs in a point release, so maybe it’d be better to roll back the pkg_resources update in 23.1, and do the upgrade + deprecate eggs in 23.2?

pfmoore · 2023-04-18T07:26:04Z

I will revert and issue a 23.1.1 bug fix release in a few days (in case there are any other bug fixes to include). For 23.2, we can have a separate discussion. The unconditional deprecation of pkg_resources still hits our users who are on 3.10 and earlier, so we may still prefer to pin to the old pkg_resources even if we do deprecate eggs (which I’m in favour of).

robsdedude · 2023-04-26T08:25:27Z

Seems like the downgrade of pkg_resources has been released in 23.1.1.

Thanks for the quick resolution 🙌
