[Linter panic] related to cache, cannot provide repro

[hauntsaninja]

With ruff 0.3.5

Possibly related to the "Different package root in cache" warning immediately prior.

I think I could repro deterministically, but then I wiped cache and no longer could reproduce.

warning: Different package root in cache: expected '/Users/shantanu/devoai/openai/project/REDACTED/REDACTEDPROJ', got '/Users/shantanu/devoai/openai/project/REDACTED/REDACTED/PROJ'
error: Panicked while linting project/REDACTED/REDACTEDPROJ/pyproject.toml: This indicates a bug in Ruff. If you could open an issue at:

    https://github.com/astral-sh/ruff/issues/new?title=%5BLinter%20panic%5D

...with the relevant file contents, the `pyproject.toml` settings, and the following stack trace, we'd be very appreciative!

[charliermarsh]

Just thinking about what this could be... Do you use the namespace-packages setting?

[charliermarsh]

(Were you upgrading from v0.3.4?)

[hauntsaninja]

No use of namespace-packages. I'm not sure what I was upgrading from, could have been v0.3.4, another possibility is v0.2.2?

Note I found the first line pretty interesting: warning: Different package root in cache: expected '/Users/shantanu/devoai/openai/project/REDACTED/REDACTEDPROJ', got '/Users/shantanu/devoai/openai/project/REDACTED/REDACTED/PROJ'

It looks like there was some package refactoring on our side that maybe the cache isn't resilient to

[MichaReiser]

@hauntsaninja did you ever run into this again or has this been resolved?

[hauntsaninja]

Ah I think I actually reported this at some other point with a clear repro and we fixed
