Defer annotation eval on Python 3.14

[cdce8p]

Fixes #13549

[RonnyPfannschmidt]

well done, thanks

[RonnyPfannschmidt]

i wonder if

Suggested change

	from annotationlib import Format
	from annotationlib import Format
	signature = partial(inspect.signature, annotation_format=Format.STRING)
	else:
	from inspect import signature

would be sufficient, it may be a bit too much of a code golf

[cdce8p]

Yes it would work but raise mypy errors as signature isn't explicitly exported.

src/_pytest/nodes.py:31: error: Module "_pytest.compat" does not explicitly export attribute "signature"  [attr-defined]
src/_pytest/fixtures.py:52: error: Module "_pytest.compat" does not explicitly export attribute "signature"  [attr-defined]

That could be resolved with from inspect import signature as signature but at that point we might as well use a dedicated function for it. That will also make it easier to understand what's going on here.

@RonnyPfannschmidt Can this PR be backported to 8.4.x in case there is another release before 8.5?

[RonnyPfannschmidt]

i see, thanks for verifying , let me add the backport label

[cdce8p]

Anything else left here? The test failures look unrelated to me.

[RonnyPfannschmidt]

Failures are unrelated
We are responsible for merging soon
