Since tox-uv just shipped lock files, I took a stab at moving attrs to a fully-locked dev environment.

Here's the experiment PR: python-attrs/attrs#1349

A problem I've run into is that packages often use dynamic packaging data that is based on git metadata (setuptools-scm, hatch-vcs, etc). As such, attrs's package version changes after every commit, which allows us to upload to test PyPI and continually verify our package. See, for example, https://test.pypi.org/project/attrs/24.2.1.dev19/

Unfortunately the current project gets locked like this:

[[package]]
name = "attrs"
version = "24.2.1.dev20"
source = { editable = "." }

Which means it's outdated after each commit, because every commit increments the number behind dev.

Is there a way around this that I've missed? If not, could there be built one? 😇 AFAICT, this is currently the biggest blocker for FOSS use from uv's side. I'm also not sure what the point of that version lock is in the first place for the current, editable project? But that's a topic for another day. :)
