Two-step cache clean and prune needed to remove package from cache

[bluss]

Removing a big package like torch or similar requires both cache clean and prune to remove it from cache. It's expected that the first clean would remove it?

uv cache clean triton
# Removed 3 files for triton (1.5KiB)
uv cache prune
# Pruning cache at: 
# Removed 316 files (553.1MiB)

uv cache clean nvidia-cudnn-cu11
# Removed 3 files for nvidia-cudnn-cu11 (1.2KiB)
uv cache prune
# Pruning cache at: 
# Removed 31 files (974.5MiB)

The packages were installed like in #6907

We can also try with another package like hatch

uvx hatch
uv cache clean hatch
# Removed 4 files for hatch (61.7KiB)
uv cache prune
# Pruning cache at: 
# Removed 1848 files (79.6MiB)

Using uv 0.4.1

No this shouldn't be required. It looks like a bug.

Not sure if this is the intended behavior, but it seems like uv cache clean <package> still leaves some dangling cache entries on Windows using the latest version:

>uv cache clean -v
DEBUG uv 0.4.2
No cache found at: C:\Users\User\AppData\Local\uv\cache

>uvx hatch --version
Installed 38 packages in 185ms <--- wow, that's confusingly fast on a cold cache
Hatch, version 1.12.0

>uv cache clean -v hatch
DEBUG uv 0.4.2
DEBUG Removing dangling cache entry: \\?\C:\Users\User\AppData\Local\uv\cache\archive-v0\zwnmKQVgeSUWVlA2QvK0E
Removed 122 files for hatch (466.2KiB)

>uv cache prune -v
DEBUG uv 0.4.2

Should be fixed in the linked PR.

[weihenglim]

The above was tested on v0.4.2, was the PR not included in that release?

[charliermarsh]

Sorry, it was but what you’re seeing isn’t the same thing. We remove all ephemeral environments when you prune. That will also remove other dependencies besides hatch.

[weihenglim]

Ah gotcha, so uv cache clean hatch will only remove hatch but not it's dependencies
