uv pip install something.whl does not install the new version

[ThiefMaster]

When installing from a local wheel file, a newer (or generally different, since it should not matter if it's newer or older) version does not get installed since uv thinks it's already there.

Here are two simple wheels (just containing a package with an empty __init__.py) to reproduce it:

• mypkg-3.3.3-py3-none-any.whl.zip
• mypkg-3.3.4-py3-none-any.whl.zip

I don't think it's relevant, but in my real application the newer wheel also contained an updated dependency and that got installed, but the updated package itself from that wheel didn't.

Also unrelated, but "Downloaded 1 package in 0.62ms" is misleading since there is no download in case of a local wheel file.

See #4011 for the download / build time.

Uh interesting so at

uv/crates/uv-installer/src/satisfies.rs

Lines 176 to 185 in d8f1de6

	if !(*requested_path == installed_path
	|| is_same_file(requested_path, &installed_path).unwrap_or(false))
	{
	trace!(
	"Path mismatch: {:?} vs. {:?}",
	requested_path,
	installed_path
	);
	return Ok(Self::Satisfied);
	}

we're detecting that these are "different" but we're treating that as satisfied.

cc @konstin / @charliermarsh looks like this was last touched in #3864?

[zanieb]

This looks wrong. I resolved your MRE with #4393 — we'll see if there's something else that was relying on this weird behavior.
