astroid crashes with RecursionError in a pytest session if schemathesis is installed

[jherbel]

Steps to reproduce

Run pytest on the following file:

import astroid

def test_something() -> None:
    astroid.parse("123")

Result without schemathesis:

Current behavior

When using astroid in pytest session with schemathesis installed, I get a RecursionError. Without schemathesis, I don't.

Expected behavior

astroid works in a pytest session if schemathesis is installed.

python -c "from astroid import __pkginfo__; print(__pkginfo__.version)" output

3.2.0

I also opened an issue with schemathesis: schemathesis/schemathesis#2170

Hi @jherbel, thanks for the report. It's possible this was just fixed on main. We'll release a patch release shortly. Would you be able to retest either then (or now, with bleeding edge)? Thanks!

[jacobtylerwalls]

Oh I see from the linked issue this may be #2191 instead.

[jherbel]

So should I test anything atm?

[jacobtylerwalls]

If you can retest with pylint 3.2.2 (which installs astroid 3.2.2) that would be a helpful data point, thanks.

Still the same crash with astroid 3.2.2.
