Allows installation of multiple toolchains in a single invocation
because I don't want to be limited to one! Most of the implementation
for concurrent downloads ported from `cargo dev fetch-python`.
## Summary
This would be a lightweight solution to
https://github.com/astral-sh/uv/issues/4307 that doesn't fully engage
with all the possibilities in the design space (but would unblock
cross-platform for now).
## Summary
In a workspace, we now read configuration from the workspace root.
Previously, we read configuration from the first `pyproject.toml` or
`uv.toml` file in path -- but in a workspace, that would often be the
_project_ rather than the workspace configuration.
We need to read configuration from the workspace root, rather than its
members, because we lock the workspace globally, so all configuration
applies to the workspace globally.
As part of this change, the `uv-workspace` crate has been renamed to
`uv-settings` and its purpose has been narrowed significantly (it no
longer discovers a workspace; instead, it just reads the settings from a
directory).
If a user has a `uv.toml` in their directory or in a parent directory
but is _not_ in a workspace, we will still respect that use-case as
before.
Closes#4249.
Closes https://github.com/astral-sh/uv/issues/3857
Instead of using custom `Arch`, `Os`, and `Libc` types I just use
`target-lexicon`'s which enumerate way more variants and implement
display and parsing. We use a wrapper type to represent a couple special
cases to support the "x86" alias for "i686" and "macos" for "darwin".
Alternatively we could try to use our `platform-tags` types but those
capture more information (like operating system versions) that we don't
have for downloads.
As discussed in https://github.com/astral-sh/uv/pull/4160, this is not
sufficient for proper libc detection but that work is larger and will be
handled separately.
## Summary
We may choose to persist these eventually, but for now, it's useful to
have them colocated with the cache, and in their own dedicated bucket
(so, at the very least, we can keep track of the use-cases).

Adds support for managed toolchain fetching to `uv venv`, e.g.

The preview flag is required. The fetch is performed if we can't find an
interpreter that satisfies the request. Once fetched, the toolchain will
be available for later invocations that include the `--preview` flag.
There will be follow-ups to improve toolchain management in general,
there is still outstanding work from the initial implementation.
## Summary
If we want more granular control over how these errors are handled, then
we need to move them out of the TOML deserialization.
No actual behavior changes here.
Part of https://github.com/astral-sh/uv/issues/4142.
Follow-up to #4016.
This exposes `Range` and `PubGrubSpecifier` from outside the resolver to
use pubgrub's union creating a dependency edge we don't really want.
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
I don't think it's worth maintaining this separate test harness for ~18
tests, when they can all be tested in the `uv` package itself. Let's
drop the maintenance burden.
## 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.
We had previously changed the signature of
`DependencyProvider::get_dependencies` to return an iterator instead of
a hashmap to avoid the conversion cost from our dependencies `Vec` to
the pubgrub's hashmap. These changes are difficult to make in pubgrub
since they complicate the public api. But we don't actually use
`DependencyProvider::get_dependencies`, so we rolled those
customizations back in https://github.com/pubgrub-rs/pubgrub/pull/226
and instead opted to change only the internal
`add_incompatibility_from_dependencies` method that we exposed in our
fork. This aligns us closer with upstream, removes the design questions
about `DependencyProvider` from our concerns and reduces our diff (not
counting the github action) to +36 -12.
We retry several kinds of network request failures, but it's often
unclear whether a request was retried or not
(https://github.com/astral-sh/uv/issues/3514#issuecomment-2105485773).
This PR adds a small intermediary layer that logs all transient request
failures, adding the `DEBUG Transient request failure` lines:
```

I decided for multi-line logging to show the complete error trace since
only `Transient request failure for https://pypi.org/simple/tqdm/,
retrying: Request error: error sending request for url
(https://pypi.org/simple/tqdm/)` doesn't tell you the actual problem (a
dns error).
Note that running with `-v` will not show messages about retry backoff
timing, but running with `RUST_LOG=debug` now shows a complete picture:
```

WARN Retry attempt #2. Sleeping 528.728192ms before the next attempt
```
Fixes#3572
The workspace test directories can be used both in tests and directly
for developing/debugging. In the latter, we shouldn't copy the venv and
the lockfile when running tests. Using the ignore crate over manual
recursion we exclude those files.

## Summary
See #3834 .
This PR adds a new namespace, `override-dependencies`, to
pyproject.toml/uv.toml.
This namespace assumes that the dependencies you want to override are
written in the form of `requirements.txt`.
a example of pyproject.toml
```toml
[project]
name = "example"
version = "0.0.0"
dependencies = [
"flask==3.0.0"
]
[tool.uv]
override-dependencies = [
"werkzeug==2.3.0"
]
```
This will improve usability by allowing you to override dependencies
without having to specify the --override option when running `uv pip
compile/install`.
## Test Plan
added test to `crates/uv/tests/pip_compile.rs`.
---------
Co-authored-by: konstin <konstin@mailbox.org>
Add a `--package` option that allows switching the current project in
the workspace. Wherever you are in a workspace, you should be able to
run with any other project as root. This is the uv equivalent of `cargo
run -p`.
I don't love the `--package` name, esp. since `-p` is already taken and
in general to many things start with p already.
Part of this change is moving the workspace discovery of
`ProjectWorkspace` to `Workspace` itself.

## Summary
This PR removes the static resolver map:
```rust
static RESOLVED_GIT_REFS: Lazy<Mutex<FxHashMap<RepositoryReference, GitSha>>> =
Lazy::new(Mutex::default);
```
With a `GitResolver` struct that we now pass around on the
`BuildContext`. There should be no behavior changes here; it's purely an
internal refactor with an eye towards making it cleaner for us to
"pre-populate" the list of resolved SHAs.
## Summary
This will help prevent bugs like #3934 by unifying the implementations
for editables and non-editable unnamed requirements. Specifically, both
of these now go through the same parsing paths and use the same struct
representations (with the exception that the editable flag is flipped in
the first case):
```
-e ./foo/bar
./foo/bar
```
We also now support PEP 508 in editable URLs. It turns out this is just
a limitation in pip, so it's correct to support it. For example, this
now works:
```
-e black[d] @ file://${PROJECT_ROOT}/scripts/packages/black_editable
```
Closes#3941.
Closes#3942.
With the change, we remove the special casing of workspace dependencies
and resolve `tool.uv` for all git and directory distributions. This
gives us support for non-editable workspace dependencies and path
dependencies in other workspaces. It removes a lot of special casing
around workspaces. These changes are the groundwork for supporting
`tool.uv` with dynamic metadata.
The basis for this change is moving `Requirement` from
`distribution-types` to `pypi-types` and the lowering logic from
`uv-requirements` to `uv-distribution`. This changes should be split out
in separate PRs.
I've included an example workspace `albatross-root-workspace2` where
`bird-feeder` depends on `a` from another workspace `ab`. There's a
bunch of failing tests and regressed error messages that still need
fixing. It does fix the audited package count for the workspace tests.
## Summary
In general, it's not quite right to filter preferences by `--reinstall`
-- we still want to respect existing versions, we just don't want to
respect _installed_ versions. But now that the installed versions and
preferences are decoupled, we can remove this (`--reinstall` is enforced
on the installed versions via the `Exclusions` struct that we pass to
the resolver).
While I was here, I also cleaned up the lockfile preference code to
better match the structure for `requirements.txt`.
