Can no longer create an editable install of typeshed-stats on Windows after upgrading to uv==0.1.3

[AlexWaygood]

I was able to create an editable install of typeshed-stats fine on Windows locally with uv==0.1.1, and I'm still able to on macOS. However, after upgrading from uv==0.1.1 to uv==0.1.3 on Windows, I now see this (using PowerShell):

PS C:\Users\alexw\coding\typeshed-stats> uv venv env

PS C:\Users\alexw\coding\typeshed-stats> env\scripts\activate
(env) PS C:\Users\alexw\coding\typeshed-stats> uv pip install -e ".[dev]"

Hmmm... probably a duplicate of #1571, I guess?

The output if I run uv pip install -e ".[dev]" --verbose:

Yeah this looks like a cache upgrade bug, if you uv clean it should be fixed

Yup, can confirm that fixed things!

[MichaReiser]

Is the uv version not a part of the cache key?

[charliermarsh]

No, the cache buckets have their own versions that we can bump. I need to look back at the history to see if we changed something in the cache representation between versions. It’s possible that I was supposed to bump a version.

[AlexWaygood]

Fun fact: I only ran into this because I was trying to repro #1612 locally 😄

[charliermarsh]

Ok, I believe I've confirmed locally that this was caused by #1556. I changed one of the cached structs, and that breaks the zero-copy representation. I should've bumped the cache version.

[charliermarsh]

Gonna merge with #1571.
