Thanks! One question about the ignores

[cclauss]

The fact that DeepSource: Python disagrees with both flake8 and ruff what code complexity is does not help the review process.

[staticdev]

@cclauss @DanielNoord to be honest, I am not very familiar with DeepSource, it was there since forever. Not sure it is a modern solution anymore. Does any of you have opinions on it already?

[cclauss]

I'm not a fan of DeepSource for Python (I find it silent but then opaque) but I hear it is quite useful for other languages.

[DanielNoord]

I would also be okay with removing it!

[DanielNoord]

I would probably open an issue for the follow up on the ignores, but other than that LGTM!

[cclauss]

Failing GitHub Actions tests fixed in:

• GitHub Actions: Use uv cache, not pip cache #2363 or
• Upgrade to uv>=0.6.0 and enable-cache #2364

[staticdev]

@cclauss after the other merges, this one needs a manual rebase.

[DanielNoord]

Still LGTM!

Thanks @cclauss

[cclauss]

What up with the Windows tests?

[DanielNoord]

A broken test added in #2331

You're not having a lot of luck with this PR, sorry!

I'll leave it to @staticdev to decide how they want to resolve this.
