For users who were using absolute paths in the `pyproject.toml`
previously, this is a behavior change: We now convert all absolute paths
in `path` entries to relative paths. Since i assume that no-one relies
on absolute path in their lockfiles - they are intended to be portable -
I'm tagging this as a bugfix.
Closes https://github.com/astral-sh/uv/pull/6438
Fixes https://github.com/astral-sh/uv/issues/6371
## Summary
The strategy here is: if the user provides supported environments, we
use those as the initial forks when resolving. As a result, we never add
or explore branches that are disjoint with the supported environments.
(If the supported environments change, we ignore the lockfile entirely,
so we don't have to worry about any interactions between supported
environments and the preference forks.)
Closes https://github.com/astral-sh/uv/issues/6184.
This already rejects `pyproject.toml`... but because the schema
validation is relaxed (we allow unknown fields, and all fields are
optional), a `pyproject.toml` doesn't get properly rejected here.
This PR makes the schema stricter, but in a safe way (by adding the
other `tool.uv` fields, like `workspace`, as any).
Closes#5832.
## Summary
Gives you a nice error message if you attempt to sync with, e.g., `-p
3.8` when that version is supported by at least one workspace member,
but your project's minimum requirement is `>=3.12`
Closes https://github.com/astral-sh/uv/issues/5662.
## Summary
When we add a new optional group in `uv add`, we never to update the
`pyproject.toml` before locking. Otherwise, we use the stale
`pyproject.toml` and omit the optional group.
Closes https://github.com/astral-sh/uv/issues/5687.
## Summary
This is surprisingly complex because we need to decide what happens if
you run `uv run` from within a hidden folder, etc. For now, I did the
simplest thing: we just ignore workspace members that are hidden
directories if they lack a `pyproject.toml`, so you can still include
hidden members, they're just ignored if they don't seem to be projects.
Closes https://github.com/astral-sh/uv/issues/5403.
## Summary
Prefers, in order:
- The major-minor version of an interpreter discovered via `--python`.
- The `requires-python` from the workspace.
- The major-minor version of the default interpreter.
If the `--python` request is a version or a version range, we use that
without fetching an interpreter.
Closes https://github.com/astral-sh/uv/issues/5299.
## Summary
You can still generate instabilities, but at least it's consistent
between including and excluding the extra.
For example, this resolves to 54 and then 52 packages on re-run:
```toml
[project]
name = "transformers"
version = "4.39.0.dev0"
description = "State-of-the-art Machine Learning for JAX, PyTorch and TensorFlow"
requires-python = ">=3.9.0"
dependencies = []
[project.optional-dependencies]
flax = ["jaxlib>=0.4.1,<=0.4.13"]
onnxruntime = ["onnxruntime>=1.4.0"]
ray = ["ray[tune]>=2.7.0"]
deepspeed-testing = [
"dill<0.3.5",
"datasets!=2.5.0",
]
[build-system]
requires = ["hatchling"]
build-backend = "hatchling.build"
```
I think the difference is just somewhere in PubGrub -- like, we add an
extra dependency, so the iteration order gets changed, and we end up
with a different resolution at the end.
Closes https://github.com/astral-sh/uv/issues/5285.
Resolves#4467.
## Summary
This PR implements the following
1. Add `tool.uv.constraint-dependencies` to pyproject.toml
1. Support to refer `tool.uv.constraint-dependencies` in `uv lock`
1. Support to refer `tool.uv.constraint-dependencies` in `uv pip
compile/install`
These are analogues of the override features implemented in #3839 and
#4369.
## Test Plan
Add test.
## 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.
## Summary
This PR introduces top-level configuration for uv, such that you can do:
```toml
[tool.uv]
index-url = "https://test.pypi.org/simple"
```
And `uv pip compile`, `uv run`, `uv tool run`, etc., will all respect
that configuration.
The settings that were escalated to the top-level remain on
`tool.uv.pip` too, but they're only respected in `uv pip` commands. If
they're specified in both places, then the `pip` settings win out.
While making this change, I also wired up some of the global options,
like `connectivity` and `native_tls`, through to all the relevant
places.
Closes#4250.

## 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`.

## Summary
This PR addresses an issue where `tool.uv` settings are not read if
`tool.uv.sources` or `tool.uv.workspaces` are present in the TOML file.
## Test Plan
Tested locally.
## Summary
This PR consolidates the concurrency limits used throughout `uv` and
exposes two limits, `UV_CONCURRENT_DOWNLOADS` and
`UV_CONCURRENT_BUILDS`, as environment variables.
Currently, `uv` has a number of concurrent streams that it buffers using
relatively arbitrary limits for backpressure. However, many of these
limits are conflated. We run a relatively small number of tasks overall
and should start most things as soon as possible. What we really want to
limit are three separate operations:
- File I/O. This is managed by tokio's blocking pool and we should not
really have to worry about it.
- Network I/O.
- Python build processes.
Because the current limits span a broad range of tasks, it's possible
that a limit meant for network I/O is occupied by tasks performing
builds, reading from the file system, or even waiting on a `OnceMap`. We
also don't limit build processes that end up being required to perform a
download. While this may not pose a performance problem because our
limits are relatively high, it does mean that the limits do not do what
we want, making it tricky to expose them to users
(https://github.com/astral-sh/uv/issues/1205,
https://github.com/astral-sh/uv/issues/3311).
After this change, the limits on network I/O and build processes are
centralized and managed by semaphores. All other tasks are unbuffered
(note that these tasks are still bounded, so backpressure should not be
a problem).
## Summary
We already _don't_ discover a `pyproject.toml` in `~/.config/uv` -- it
must be `uv.toml`. This PR makes the same change for `--config-file` --
it _has_ to be a `uv.toml`.
I think this is reasonable and more consistent, though I'm not sure. A
`pyproject.toml` "means" something -- it defines a project itself, in
which case we should be using project configuration. But creating a
`pyproject.toml` outside the project and passing it via `--config-file`
seems like an anti-pattern.
## Summary
This PR follows Cargo's strategy for merging configuration, albeit in a
more limited way (we don't support as many configuration locations).
Specifically, we merge the user configuration with the workspace
configuration if both are present. The workspace configuration has
priority, such that we take values from the workspace configuration and
ignore those in the user configuration if both are specified for a given
setting -- with the exception of arrays and maps, which are
concatenated.
For now, if a user provides a configuration file with `--config-file`,
we _don't_ merge in the user settings.

Closes#3420.
