• Python version: 3.12.4
• Operating System: Linux

Description

After upgrading to 3.12.4 the signature errors about recursive_guard are gone, but we're seeing a number of TypeErrors and one AssertionError while running the tests.

Note that your CI still seems to be testing against 3.12.3 as of https://github.com/Fatal1ty/mashumaro/commit/e945ee4319db49da9f7b8ede614e988cc8c8956b.

Oh, we missed this because 3.12.4 still hasn't been added to github actions:

• https://github.com/actions/setup-python/issues/883

I'll debug it on my laptop as soon as I have free time.

Fixed? https://github.com/Fatal1ty/mashumaro/commit/01b1d795e71ecb86c6c36a3b537473a9246df194

[mweinelt]

This fixes the issues on 3.13.0, but 3.13.1 came with other issues.

[Fatal1ty]

Interesting. Just installed 3.12.4 using pyenv and couldn't reproduce errors while running tests.

Python 3.12.4 (main, Jun 22 2024, 12:38:27) [Clang 15.0.0 (clang-1500.3.9.4)] on darwin
Type "help", "copyright", "credits" or "license" for more information.

I believe this was fixed in CPython itself:

[mweinelt]

Yeah, same here. Not sure where they went for us, since we were on 3.12.4 at the time already.
