Previously, distributions created through `Source::Workspace` would have
the absolute path as lock path. This didn't cause any problems, since in
`Urls` we would later overwrite those urls with the correct one created
from being workspace members by path.
Changing the order surfaced this. This change emits the correct lock
path. I've manually checked the difference with `dbg!`, this is not
observable on main, but on the diverging urls branch it fixes lockfile
creation.
Previously, `b` in the test case would have been incorrectly locked to
the path of `a`. I've moved `relative_to` into uv-fs since it's now used
in two different places.
Previously failing lockfile when `a/pyproject.toml` and
`a/b/pyproject.toml` exist (not in a workspace) and `a` was depending on
`b`:
```toml
version = 1
requires-python = ">=3.11, <3.13"
[[distribution]]
name = "b"
version = "0.1.0"
source = "directory+/home/konsti/projects/uv/a"
sdist = { path = "/home/konsti/projects/uv/a" }
[[distribution]]
name = "black"
version = "0.1.0"
source = "editable+."
sdist = { path = "." }
[[distribution.dependencies]]
name = "b"
version = "0.1.0"
source = "directory+/home/konsti/projects/uv/a"
```
## Summary
This is what I consider to be the "real" fix for #8072. We now treat
directory and path URLs as separate `ParsedUrl` types and
`RequirementSource` types. This removes a lot of `.is_dir()` forking
within the `ParsedUrl::Path` arms and makes some states impossible
(e.g., you can't have a `.whl` path that is editable). It _also_ fixes
the `direct_url.json` for direct URLs that refer to files. Previously,
we wrote out to these as if they were installed as directories, which is
just wrong.
By splitting `path` into a lockable, relative (or absolute) and an
absolute installable path and by splitting between urls and paths by
dist type, we can store relative paths in the lockfile.
When creating a lockfile, lock the combined dependencies for all
packages in a workspace. This make the lockfile independent of where you
are in the workspace.
Fixes#3983
## Summary
Externally, development dependencies are currently structured as a flat
list of PEP 580-compatible requirements:
```toml
[tool.uv]
dev-dependencies = ["werkzeug"]
```
When locking, we lock all development dependencies; when syncing, users
can provide `--dev`.
Internally, though, we model them as dependency groups, similar to
Poetry, PDM, and [PEP 735](https://peps.python.org/pep-0735). This
enables us to change out the user-facing frontend without changing the
internal implementation, once we've decided how these should be exposed
to users.
A few important decisions encoded in the implementation (which we can
change later):
1. Groups are enabled globally, for all dependencies. This differs from
extras, which are enabled on a per-requirement basis. Note, however,
that we'll only discover groups for uv-enabled packages anyway.
2. Installing a group requires installing the base package. We rely on
this in PubGrub to ensure that we resolve to the same version (even
though we only expect groups to come from workspace dependencies anyway,
which are unique). But anyway, that's encoded in the resolver right now,
just as it is for extras.
## Summary
This PR separates "gathering the requirements" from the rest of the
metadata (e.g., version), which isn't required when installing a
package's _dependencies_ (as opposed to installing the package itself).
It thus ensures that we don't need to build a package when a static
`pyproject.toml` is provided in `pip compile`.
