Ruff: Lint failed - error: Ruff crashed.

[david-waterworth]

I got this message as a 'pop-up' from vscode

Ruff: Lint failed (
error: Ruff crashed. If you could open an issue at:

    https://github.com/astral-sh/ruff/issues/new?title=%5BPanic%5D

...quoting the executed command, along with the relevant file contents and `pyproject.toml` settings, we'd be very appreciative!

I guess it's from the vscode extension (extension v2024.22.0)

My pyproject.toml contains

Can you provide the source code on which it crashed? Also, the Ruff version used by the extension? There's just one unwrap in the file which shouldn't really fail.

[david-waterworth]

Sorry I have no idea what code it crashed on and I closed vscode shortly after seeing the error, and the pop-up message doesn't say (I think it was from the vscode notification system - the bell icon in the lower rhs of the bottom window border). If it happens again I'll try and figure it out - I've seen it several times but not been able to work out what it means.

I'm using extension version v2024.22.0 which according to the docs ships with ruff==0.4.5 (I also have ruff==0.4.6 installed globally via pipx and my project uses the ruff precommit hook (https://github.com/astral-sh/ruff-pre-commit) which is version 0.4.4 - so I'm only assuming it was the version from the extension that was running because the other two shouldn't be running in the background afaik.

All good @david-waterworth. That trace usually means Ruff had a problem with the specific contents of the file, so if you see it again, do you mind sharing them here (if you can)? Otherwise hard for us to resolve.

I'll close this for now as there's nothing actionable for us to do. @david-waterworth let us know if you still run into this and I'm happy to re-open the issue.
