Thanks! Wow, that came around quickly.

I had to think this through again, but I think this is correct: this is a deprecation for Python 3.16, which will become stable in autumn 2027, around the same time that Python 3.11 goes end-of-life. That means that the deprecation warnings will start to be emitted at basically the same time that the lowest non-EOL Python version is Python 3.12 -- and Python 3.12 is the first version in which users can use PEP-695 syntax

[AlexWaygood]

the test failures from the deprecation warnings in setuptools in https://github.com/python/cpython/actions/runs/26230364757/job/77188896358?pr=150190 do seem a bit concerning. Do we need to update setuptools before landing this?

[github-actions]

This PR is stale because it has been open for 90 days with no activity.

[sobolevn]

Setuptools is updated, new version is released. I've fixed all merge conflicts.

[sobolevn]

We can address the setuptools.whl tests failures in two ways:

1. We can update the bundled .whl to a newer version
2. Or we can add warnings ignore guards

I think that both have their downsides, but I would probably go with 1 :)

[sobolevn]

I created #160824 to discuss the setuptools update.

[sobolevn]

I fixed setuptools, updated the bundled wheel file, now tests should pass (finally 🎉)!

Please, take another look :)

[sobolevn]

Thanks a lot, everyone! 🎉

Looks like this has caused buildbot refleak failures:

https://buildbot.python.org/release-status

For example:

• Before: https://buildbot.python.org/#/builders/853/builds/4488
• After: https://buildbot.python.org/#/builders/853/builds/4489

The other test that does import_helper.import_fresh_module('typing') has self.addCleanup(atexit.unregister, typing._clear_caches).

cpython/Lib/test/test_typing.py

Lines 6570 to 6585 in 3feccd1

	def test_collect_parameters(self):
	typing = import_helper.import_fresh_module("typing")
	# Importing typing registers an internal function named _clear_caches
	# with atexit. The throwaway module created here installs its own
	# handler, which holds the module alive and keeps references until
	# interpreter shutdown even after the test finishes. Each repetition
	# of this test under -R would therefore leak another module copy. To
	# avoid this, we unregister the handler once the test is done.
	self.addCleanup(atexit.unregister, typing._clear_caches)
	with self.assertWarnsRegex(
	DeprecationWarning,
	"The private _collect_parameters function is deprecated"
	) as cm:
	typing._collect_parameters
	self.assertEqual(cm.filename, __file__)

Do we need similar in test_any_str_deprecated?

[sobolevn]

Oups, sorry for that! Fixing :)
