Docs say cache is $HOME/Library/Caches/uv but that may not be correct

[simonw]

The docs here:

uv/docs/reference/cli.md

Lines 90 to 92 in be92a2b

	</dd><dt><code>--cache-dir</code> <i>cache-dir</i></dt><dd><p>Path to the cache directory.</p>
	<p>Defaults to <code>$HOME/Library/Caches/uv</code> on macOS, <code>$XDG_CACHE_HOME/uv</code> or <code>$HOME/.cache/uv</code> on Linux, and <code>%LOCALAPPDATA%\uv\cache</code> on Windows.</p>

Say that the cache directory...

Defaults to $HOME/Library/Caches/uv on macOS

But... I had a look on my Mac in ~/Library/Caches and there was no uv folder.

What I did find was this:

/Users/simon/Library/Caches/com.apple.python/Users/simon/Library/Caches/uv

So either the documentation here needs updating or there's some kind of weird bug going on, or I'm missing something else.

I found what looks to be the real uv cache directory here:

/Users/simon/.cache/uv

That weird com.apple.python one turned out to be mostly empty:

find /Users/simon/Library/Caches/com.apple.python/Users/simon/Library/Caches/uv

/Users/simon/Library/Caches/com.apple.python/Users/simon/Library/Caches/uv
/Users/simon/Library/Caches/com.apple.python/Users/simon/Library/Caches/uv/archive-v0
/Users/simon/Library/Caches/com.apple.python/Users/simon/Library/Caches/uv/archive-v0/0VSKRv7KPsU6OVxKhRKyA
/Users/simon/Library/Caches/com.apple.python/Users/simon/Library/Caches/uv/archive-v0/0VSKRv7KPsU6OVxKhRKyA/lib
/Users/simon/Library/Caches/com.apple.python/Users/simon/Library/Caches/uv/archive-v0/0VSKRv7KPsU6OVxKhRKyA/lib/python3.9
/Users/simon/Library/Caches/com.apple.python/Users/simon/Library/Caches/uv/archive-v0/0VSKRv7KPsU6OVxKhRKyA/lib/python3.9/site-packages
/Users/simon/Library/Caches/com.apple.python/Users/simon/Library/Caches/uv/archive-v0/0VSKRv7KPsU6OVxKhRKyA/lib/python3.9/site-packages/_virtualenv.cpython-39.pyc

This one was VERY full:

find /Users/simon/.cache/uv | wc -l

  127275

du -h ~/.cache/uv | tail -n 1

3.7G	/Users/simon/.cache/uv

We switched to XDG in #5806 — looks like we forgot to update this doc. It can be there for backwards compatibility reasons, but new installs use the XDG standard location.

Also useful (for other people exploring this):

uv cache dir

On my machine outputs:

/Users/simon/.cache/uv
