## Summary
We already support `tool.uv.dev-dependencies` in the legacy
non-`[project]` projects. This adds equivalent support for
`[dependency-groups]`, e.g.:
```toml
[tool.uv.workspace]
[dependency-groups]
lint = ["ruff"]
```
This PR adds support for `tool.uv.default-groups`, which defaults to
`["dev"]` for backwards-compatibility. These represent the groups we
sync by default.
Part of #8090
Unblocks https://github.com/astral-sh/uv/pull/8274
Refactors `DevMode` and `DevSpecification` into a shared type
`DevGroupsSpecification` that allows us to track if `--dev` was
implicitly or explicitly provided.
Part of #8090
Adds the ability to add and remove dependencies from arbitrary groups
using `uv add` and `uv remove`. Does not include resolving with the new
dependencies — tackling that in #8110.
Additionally, this does not yet resolve interactions with the existing
`dev` group — we'll tackle that separately as well. I probably won't
merge the stack until that design is resolved.
## Summary
We were including dependencies that were only included by a dependency
that isn't relevant on the current platform (i.e., we were enforcing the
"current environment" at one level, but not transitively).
Closes https://github.com/astral-sh/uv/issues/8516.
## Summary
Historically, we haven't enforced schema versions. This PR adds a
versioning policy such that, if a uv version writes schema v2, then...
- It will always reject lockfiles with schema v3 or later.
- It _may_ reject lockfiles with schema v1, but can also choose to read
them, if possible.
(For example, the change we proposed to rename `dev-dependencies` to
`dependency-groups` would've been backwards-compatible: newer versions
of uv could still read lockfiles that used the `dev-dependencies` field
name, but older versions should reject lockfiles that use the
`dependency-groups` field name.)
Closes https://github.com/astral-sh/uv/issues/8465.
## Summary
Previously, `uv tree --package` had some strange behavior due to how we
were computing the root nodes. This PR refactors the entire
implementation to use `petgraph` so we can do proper operations on a
graph structure.
Closes https://github.com/astral-sh/uv/issues/8382.
## Summary
This is part of making
https://github.com/astral-sh/uv/issues/7299#issuecomment-2385286341
better. You can now use `tool.uv.dependency-metadata` for direct URL
requirements. Unfortunately, you _must_ include a version, since we need
one to perform resolution.
## Summary
If the user has an upper-bound in a `requires-python`, we don't
correctly narrow it during resolution. We should be narrowing based on
the intersection.
Closes#8297.
## Summary
Rather than relying on the distribution and package URL being the same
(which isn't true for Git dependencies), we can just use the
intersection of the markers directly.
Closes https://github.com/astral-sh/uv/issues/8381.
Part of https://github.com/astral-sh/uv/issues/2777
I noticed we're seeing "Python ABI" _a lot_ in error messages which I
did not expect. This improves a common case by being a little more
specific.
When patch version isn't specified and a matching version is referenced,
it will default patch to 0 which could be unclear/confusing. This PR
warns the user of that default.

## Summary
If you pass a named index via the CLI, you can now reference it as a
named source. This required some surprisingly large refactors, since we
now need to be able to track whether a given index was provided on the
CLI vs. elsewhere (since, e.g., we don't want users to be able to
reference named indexes defined in global configuration).
Closes https://github.com/astral-sh/uv/issues/7899.
## Summary
This PR lifts the restriction that a package must come from a single
index. For example, you can now do:
```toml
[project]
name = "project"
version = "0.1.0"
readme = "README.md"
requires-python = ">=3.12"
dependencies = ["jinja2"]
[tool.uv.sources]
jinja2 = [
{ index = "torch-cu118", marker = "sys_platform == 'darwin'"},
{ index = "torch-cu124", marker = "sys_platform != 'darwin'"},
]
[[tool.uv.index]]
name = "torch-cu118"
url = "https://download.pytorch.org/whl/cu118"
[[tool.uv.index]]
name = "torch-cu124"
url = "https://download.pytorch.org/whl/cu124"
```
The construction is very similar to the way we handle URLs today: you
can have multiple URLs for a given package, but they must appear in
disjoint forks. So most of the code is just adding that abstraction to
the resolver, following our handling of URLs.
Closes#7761.
## Summary
This PR enables users to provide index credentials via named environment
variables.
For example, given an index named `internal` that requires a username
(`public`) and password
(`koala`), you can define the index (without credentials) in your
`pyproject.toml`:
```toml
[[tool.uv.index]]
name = "internal"
url = "https://pypi-proxy.corp.dev/simple"
```
Then set the `UV_INDEX_INTERNAL_USERNAME` and
`UV_INDEX_INTERNAL_PASSWORD`
environment variables, where `INTERNAL` is the uppercase version of the
index name:
```sh
export UV_INDEX_INTERNAL_USERNAME=public
export UV_INDEX_INTERNAL_PASSWORD=koala
```
## Summary
This PR adds a first-class API for defining registry indexes, beyond our
existing `--index-url` and `--extra-index-url` setup.
Specifically, you now define indexes like so in a `uv.toml` or
`pyproject.toml` file:
```toml
[[tool.uv.index]]
name = "pytorch"
url = "https://download.pytorch.org/whl/cu121"
```
You can also provide indexes via `--index` and `UV_INDEX`, and override
the default index with `--default-index` and `UV_DEFAULT_INDEX`.
### Index priority
Indexes are prioritized in the order in which they're defined, such that
the first-defined index has highest priority.
Indexes are also inherited from parent configuration (e.g., the
user-level `uv.toml`), but are placed after any indexes in the current
project, matching our semantics for other array-based configuration
values.
You can mix `--index` and `--default-index` with the legacy
`--index-url` and `--extra-index-url` settings; the latter two are
merely treated as unnamed `[[tool.uv.index]]` entries.
### Index pinning
If an index includes a name (which is optional), it can then be
referenced via `tool.uv.sources`:
```toml
[[tool.uv.index]]
name = "pytorch"
url = "https://download.pytorch.org/whl/cu121"
[tool.uv.sources]
torch = { index = "pytorch" }
```
If an index is marked as `explicit = true`, it can _only_ be used via
such references, and will never be searched implicitly:
```toml
[[tool.uv.index]]
name = "pytorch"
url = "https://download.pytorch.org/whl/cu121"
explicit = true
[tool.uv.sources]
torch = { index = "pytorch" }
```
Indexes defined outside of the current project (e.g., in the user-level
`uv.toml`) can _not_ be explicitly selected.
(As of now, we only support using a single index for a given
`tool.uv.sources` definition.)
### Default index
By default, we include PyPI as the default index. This remains true even
if the user defines a `[[tool.uv.index]]` -- PyPI is still used as a
fallback. You can mark an index as `default = true` to (1) disable the
use of PyPI, and (2) bump it to the bottom of the prioritized list, such
that it's used only if a package does not exist on a prior index:
```toml
[[tool.uv.index]]
name = "pytorch"
url = "https://download.pytorch.org/whl/cu121"
default = true
```
### Name reuse
If a name is reused, the higher-priority index with that name is used,
while the lower-priority indexes are ignored entirely.
For example, given:
```toml
[[tool.uv.index]]
name = "pytorch"
url = "https://download.pytorch.org/whl/cu121"
[[tool.uv.index]]
name = "pytorch"
url = "https://test.pypi.org/simple"
```
The `https://test.pypi.org/simple` index would be ignored entirely,
since it's lower-priority than `https://download.pytorch.org/whl/cu121`
but shares the same name.
Closes#171.
## Future work
- Users should be able to provide authentication for named indexes via
environment variables.
- `uv add` should automatically write `--index` entries to the
`pyproject.toml` file.
- Users should be able to provide multiple indexes for a given package,
stratified by platform:
```toml
[tool.uv.sources]
torch = [
{ index = "cpu", markers = "sys_platform == 'darwin'" },
{ index = "gpu", markers = "sys_platform != 'darwin'" },
]
```
- Users should be able to specify a proxy URL for a given index, to
avoid writing user-specific URLs to a lockfile:
```toml
[[tool.uv.index]]
name = "test"
url = "https://private.org/simple"
proxy = "http://<omitted>/pypi/simple"
```
## Summary
This PR declares and documents all environment variables that are used
in one way or another in `uv`, either internally, or externally, or
transitively under a common struct.
I think over time as uv has grown there's been many environment
variables introduced. Its harder to know which ones exists, which ones
are missing, what they're used for, or where are they used across the
code. The docs only documents a handful of them, for others you'd have
to dive into the code and inspect across crates to know which crates
they're used on or where they're relevant.
This PR is a starting attempt to unify them, make it easier to discover
which ones we have, and maybe unlock future posibilities in automating
generating documentation for them.
I think we can split out into multiple structs later to better organize,
but given the high influx of PR's and possibly new environment variables
introduced/re-used, it would be hard to try to organize them all now
into their proper namespaced struct while this is all happening given
merge conflicts and/or keeping up to date.
I don't think this has any impact on performance as they all should
still be inlined, although it may affect local build times on changes to
the environment vars as more crates would likely need a rebuild. Lastly,
some of them are declared but not used in the code, for example those in
`build.rs`. I left them declared because I still think it's useful to at
least have a reference.
Did I miss any? Are their initial docs cohesive?
Note, `uv-static` is a terrible name for a new crate, thoughts? Others
considered `uv-vars`, `uv-consts`.
## Test Plan
Existing tests
As per
https://matklad.github.io/2021/02/27/delete-cargo-integration-tests.html
Before that, there were 91 separate integration tests binary.
(As discussed on Discord — I've done the `uv` crate, there's still a few
more commits coming before this is mergeable, and I want to see how it
performs in CI and locally).
## Summary
In the routine we use to verify whether the lockfile is up-to-date, we
sometimes have to resolve package metadata. If that resolution step
fails, the resolver is left in a bad state, as various tasks are marked
as pending despite the error. Treating that as a recoverable failure
thus leads to a deadlock.
This PR modifies the errors to be treated as fatal.
I think a more holistic fix here would be to add some kind of guard to
ensure that any tasks that fail are no longer marked as pending (or
enforce this in the type system).
Closes https://github.com/astral-sh/uv/issues/8074.
## Summary
The issue here is that, if you user has a `requires-python` like `>=
3.7, != 3.8.5`, this gets expanded to the following bounds:
- `[3.7, 3.8.5)`
- `(3.8.5, ...`
We then convert this to the specific `>= 3.7, < 3.8.5, > 3.8.5`. But the
commas in that expression are conjunctions... So it's impossible to
satisfy? No version is both `< 3.8.5` and `> 3.8.5`.
Instead, we now preserve the input `requires-python` and just
concatenate the terms, only using PubGrub to compute the _bounds_.
Closes https://github.com/astral-sh/uv/issues/7862.
Unlike `cp36-...`, which requires exactly CPython 3.6, `py36-none` is
compatible with all versions starting at Python 3.6.
Note that `py3x-none` should not be used. Instead, use `py3-none` with
`requires-python`.
Fixes#7800
## Summary
If a supported environment includes a Python marker, we don't simplify
it out, despite _storing_ the simplified markers. This PR modifies the
validation code to compare simplified to simplified markers.
Closes https://github.com/astral-sh/uv/issues/7876.
## Summary
When using `uv tree --package foo`, an extra empty line appears at the
beginning, which seems unnecessary since `uv tree` without the package
option doesn’t have this. It’s possible that the intention was to add
separation between packages, i.e. the correct implementation shoule be:
```rust
if !std::mem::take(&mut first) {
lines.push(String::new());
}
```
Even if corrected, this extra spacing might be redundant as `uv tree`
doesn’t include these empty lines between packages by default.
```console
$ uv init project
$ cd project
$ uv init foo
$ uv tree
Using CPython 3.12.5
Resolved 2 packages in 1ms
foo v0.1.0
project v0.1.0
$ uv tree --package project
Using CPython 3.12.5
Resolved 2 packages in 1ms
project v0.1.0
```
Would it be okay to expose this struct? We currently use our own
ResolveProvider, and it would be nice to use the `FlatDistributions` for
easy `VersionMap` creation.
Thanks!
## Summary
`click` has one dependency of `colorama` only on Windows, `uv tree
--invert` should not include `colorama` on non-Windows platforms, but
currently:
```console
$ uv init
$ uv add click
$ uv tree --invert --python-platform macos
colorama v0.4.6
```
it should:
```console
$ uv tree --invert --python-platform macos
click v8.1.7
└── project v0.1.0
```
#7226 modified the check to skip prefetching of source dists without
proper minimum-version bounds, and wound up flipping the boolean
expression. This change flips the some/none expression so that the
intended skip happens as expected.
Fixes#7680.
This PR adds some additional sanity checking on resolution graphs to
ensure we can never install different versions of the same package into
the same environment.
I used code similar to this to provoke bugs in the resolver before the
release, but it never made it into `main`. Here, we add the error
checking to the creation of `ResolutionGraph`, since this is where it's
most convenient to access the "full" markers of each distribution.
We only report an error when `debug_assertions` are enabled to avoid
rendering `uv` *completely* unusuable if a bug were to occur in a
production binary. For example, maybe a conflict is detected in a marker
environment that isn't actually used. While not ideal, `uv` is still
usable for any other marker environment.
Closes#5598
