## Summary
Detects unused cache entries, which can come in a few forms:
1. Directories that are out-dated via our versioning scheme.
2. Old source distribution builds (i.e., we have a more recent version).
3. Old wheels (stored in `archive-v0`, but not symlinked-to from
anywhere in the cache).
Closes https://github.com/astral-sh/puffin/issues/1059.
Scott schafer got me the idea: We can avoid repeating the path for
workspaces dependencies everywhere if we declare them in the virtual
package once and treat them as workspace dependencies from there on.
## Summary
I tried out `cargo shear` to see if there are any unused dependencies
that `cargo udeps` isn't reporting. It turned out, there are a few. This
PR removes those dependencies.
## Test Plan
`cargo build`
First, replace all usages in files in-place. I used my editor for this.
If someone wants to add a one-liner that'd be fun.
Then, update directory and file names:
```
# Run twice for nested directories
find . -type d -print0 | xargs -0 rename s/puffin/uv/g
find . -type d -print0 | xargs -0 rename s/puffin/uv/g
# Update files
find . -type f -print0 | xargs -0 rename s/puffin/uv/g
```
Then add all the files again
```
# Add all the files again
git add crates
git add python/uv
# This one needs a force-add
git add -f crates/uv-trampoline
```
