This is a rewrite of the groups subsystem to have more clear semantics,
and some adjustments to the CLI flag constraints. In doing so, the
following bugs are fixed:
* `--no-default-groups --no-group foo` is no longer needlessly rejected
* `--all-groups --no-default-groups` now correctly evaluates to
`--all-groups` where previously it was erroneously being interpretted as
just `--no-default-groups`
* `--all-groups --only-dev` is now illegal, where previously it was
accepted and mishandled, as if it was a mythical `--only-all-groups`
flag
Fixes#10890Closes#10891
This was an oversight in the implementation, thankfully it appears to be
a simple fix? (My only hesitation is this implementation essentially
claims that --only-group is defacto incompatible with --extra and I
*think* that's the case but I'm not certain.)
Ultimately this is a lot of settings plumbing and a couple minor pieces
of Actual Logic (which are so simple I have to assume there's something
missing, but maybe not!).
Note this "needlessly" use DevDependencyGroup since it costs nothing, is
more futureproof, and lets us maintain one primary interface (we just
pass `false` for all the dev arguments).

## Summary
I needed this for https://github.com/astral-sh/uv/pull/10794, but it
makes sense as a standalone change, since it's much more testable. We
can also reuse this in at least one more place.
## Summary
This PR modifies the lockfile to omit versions for source trees that use
`dynamic` versioning, thereby enabling projects to use dynamic
versioning with `uv.lock`.
Prior to this change, dynamic versioning was largely incompatible with
locking, especially for popular tools like `setuptools_scm` -- in that
case, every commit bumps the version, so every commit invalidates the
committed lockfile.
Closes https://github.com/astral-sh/uv/issues/7533.
## Summary
This PR revives https://github.com/astral-sh/uv/pull/7827 to improve
tool resolutions such that, if the resolution fails, and the selected
interpreter doesn't match the required Python version from the solve, we
attempt to re-solve with a newly-discovered interpreter that _does_
match the required Python version.
For now, we attempt to choose a Python interpreter that's greater than
the inferred `requires-python`, but compatible with the same Python
minor. This helps avoid successive failures for cases like Posting,
where choosing Python 3.13 fails because it has a dependency that lacks
source distributions and doesn't publish any Python 3.13 wheels. We
should further improve the strategy to solve _that_ case too, but this
is at least the more conservative option...
In short, if you do `uv tool instal posting`, and we find Python 3.8 on
your machine, we'll detect that `requires-python: >=3.11`, then search
for the latest Python 3.11 interpreter and re-resolve.
Closes https://github.com/astral-sh/uv/issues/6381.
Closes https://github.com/astral-sh/uv/issues/10282.
## Test Plan
The following should succeed:
```
cargo run python uninstall --all
cargo run python install 3.8
cargo run tool install posting
```
In the logs, we see:
```

## Summary
When `--upgrade` is provided, we should retain already-installed
packages _if_ they're newer than whatever is available from the
registry.
Closes https://github.com/astral-sh/uv/issues/10089.
## Summary
Sort of undecided on this. These are already stored as `dyn Reporter` in
each struct, so we're already using dynamic dispatch in that sense. But
all the methods take `impl Reporter`. This is sometimes nice (the
callsites are simpler?), but it also means that in practice, you often
_can't_ pass `None` to these methods that accept `Option<impl
Reporter>`, because Rust can't infer the generic type.
Anyway, this adds more consistency and simplifies the setup by using
`Arc<dyn Reporter>` everywhere.
Build failures are one of the most common user facing failures that
aren't "obivous" errors (such as typos) or resolver errors. Currently,
they show more technical details than being focussed on this being an
error in a subprocess that is either on the side of the package or -
more likely - in the build environment, e.g. the user needs to install a
dev package or their python version is incompatible.
The new error message clearly delineates the part that's important (this
is a build backend problem) from the internals (we called this hook) and
is consistent about which part of the dist building stage failed. We
have to calibrate the exact wording of the error message some more. Most
of the implementation is working around the orphan rule, (this)error
rules and trait rules, so it came out more of a refactoring than
intended.
Example:

## Summary
Small thing I noticed while working on another change: if we error when
extracting `requires-dist`, we go through the full metadata build. We
need to distinguish between fatal errors and "the data isn't static".
Instead of modifying the error to replace a dummy derivation chain from
construction with the real one, build the error with the real derivation
chain directly.
This came up when trying to improve the build error reporting.
Introduces `DistErrorKind` to avoid error variants for each case that
are only different in one line of the message.
## Summary
Today, our dependency group implementation is a little awkward... For
each package `P`, we check if `P` contains dependencies for each enabled
group, then add a dependency on `P` with the group enabled. There are a
few issues here:
1. It's sort of backwards... We add a dependency from the base package
`P` to `P` with the group enabled. Then `P` with the group enabled adds
a dependency on the base package.
2. We can't, e.g., enable different groups for different packages. (We
don't have a way for users to specify this on the CLI, but there's no
reason that it should be _impossible_ in the resolver.)
3. It's inconsistent with how extras work, which leads to confusing
differences in the resolver.
Instead, our internal requirement type can now include dependency
groups, which makes dependency groups look much, much more like extras
in the resolver.

## Summary
Resolves#9333
This pull request introduces support for the `--no-extra` command-line
flag and the corresponding `no-extra` UV setting.
### Behavior
- When `--all-extras` is supplied, the specified extras in `--no-extra`
will be excluded from the installation.
- If `--all-extras` is not supplied, `--no-extra` has no effect and is
safely ignored.
## Test Plan
Since `ExtrasSpecification::from_args` and
`ExtrasSpecification::extra_names` are the most important parts in the
implementation, I added the following tests in the
`uv-configuration/src/extras.rs` module:
- **`test_no_extra_full`**: Verifies behavior when `no_extra` includes
the entire list of extras.
- **`test_no_extra_partial`**: Tests partial exclusion, ensuring only
specified extras are excluded.
- **`test_no_extra_empty`**: Confirms that no extras are excluded if
`no_extra` is empty.
- **`test_no_extra_excessive`**: Ensures the implementation ignores
`no_extra` values that don't match any available extras.
- **`test_no_extra_without_all_extras`**: Validates that `no_extra` has
no effect when `--all-extras` is not supplied.
- **`test_no_extra_without_package_extras`**: Confirms correct behavior
when no extras are available in the package.
- **`test_no_extra_duplicates`**: Verifies that duplicate entries in
`pkg_extras` or `no_extra` do not cause errors.

## Summary
The issue here is fairly complex. Consider the following:
```toml
[project]
name = "project"
version = "0.1.0"
requires-python = ">=3.12.0"
dependencies = []
[project.optional-dependencies]
cpu = [
"torch>=2.5.1",
"torchvision>=0.20.1",
]
cu124 = [
"torch>=2.5.1",
"torchvision>=0.20.1",
]
[tool.uv]
conflicts = [
[
{ extra = "cpu" },
{ extra = "cu124" },
],
]
[tool.uv.sources]
torch = [
{ index = "pytorch-cpu", extra = "cpu", marker = "platform_system != 'Darwin'" },
]
torchvision = [
{ index = "pytorch-cpu", extra = "cpu", marker = "platform_system != 'Darwin'" },
]
[[tool.uv.index]]
name = "pytorch-cpu"
url = "https://download.pytorch.org/whl/cpu"
explicit = true
```
When solving this project, we first pick a PyTorch version from PyPI, to
solve the `cu124` extra, selecting `2.5.1`.
Later, we try to solve the `cpu` extra. In solving that extra, we look
at the PyTorch CPU index. Ideally, we'd select `2.5.1+cpu`... But
`2.5.1` is already a preference. So we choose that.
Now, we only respect preferences for explicit indexes if they came from
the same index.
Closes https://github.com/astral-sh/uv/issues/9295.
## Summary
This PR adds context to our error messages to explain _why_ a given
package was included, if we fail to download or build it.
It's quite a large change, but it motivated some good refactors and
improvements along the way.
Closes https://github.com/astral-sh/uv/issues/8962.
After https://github.com/astral-sh/uv/pull/8797, we have spec-compliant
handling for local version identifiers and can completely remove all the
special-casing around it.
This updates the surrounding code to use the new ResolverEnvironment
type. In some cases, this simplifies caller code by removing case
analysis. There *shouldn't* be any behavior changes here. Some test
snapshots were updated to account for some minor tweaks to error
messages.
I didn't split this up into separate commits because it would have been
too difficult/costly.
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
We can't rely on reading these from the `pyproject.toml`; instead, we
resolve the project metadata (which will typically just require reading
the `pyproject.toml`, but will go through our standard metadata paths).
Closes https://github.com/astral-sh/uv/issues/8071.
## Summary
This was brought up on Twitter recently. `dotenv` hasn't been updated in
years and doesn't build successfully anymore. Users almost always mean
to install `python-dotenv`. I think we can add helpful hints here to
point users in the right direction.
## Test Plan

## Summary
Use a dedicated source type for non-package requirements. Also enables
us to support non-package `path` dependencies _and_ removes the need to
have the member `pyproject.toml` files available when we sync _and_
makes it explicit which dependencies are virtual vs. not (as evidenced
by the snapshot changes). All good things!
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
This PR rewrites the `MarkerTree` type to use algebraic decision
diagrams (ADD). This has many benefits:
- The diagram is canonical for a given marker function. It is impossible
to create two functionally equivalent marker trees that don't refer to
the same underlying ADD. This also means that any trivially true or
unsatisfiable markers are represented by the same constants.
- The diagram can handle complex operations (conjunction/disjunction) in
polynomial time, as well as constant-time negation.
- The diagram can be converted to a simplified DNF form for user-facing
output.
The new representation gives us a lot more confidence in our marker
operations and simplification, which is proving to be very important
(see https://github.com/astral-sh/uv/pull/5733 and
https://github.com/astral-sh/uv/pull/5163).
Unfortunately, it is not easy to split this PR into multiple commits
because it is a large rewrite of the `marker` module. I'd suggest
reading through the `marker/algebra.rs`, `marker/simplify.rs`, and
`marker/tree.rs` files for the new implementation, as well as the
updated snapshots to verify how the new simplification rules work in
practice. However, a few other things were changed:
- [We now use release-only comparisons for `python_full_version`, where
we previously only did for
`python_version`](https://github.com/astral-sh/uv/blob/ibraheem/canonical-markers/crates/pep508-rs/src/marker/algebra.rs#L522).
I'm unsure how marker operations should work in the presence of
pre-release versions if we decide that this is incorrect.
- [Meaningless marker expressions are now
ignored](https://github.com/astral-sh/uv/blob/ibraheem/canonical-markers/crates/pep508-rs/src/marker/parse.rs#L502).
This means that a marker such as `'x' == 'x'` will always evaluate to
`true` (as if the expression did not exist), whereas we previously
treated this as always `false`. It's negation however, remains `false`.
- [Unsatisfiable markers are written as `python_version <
'0'`](https://github.com/astral-sh/uv/blob/ibraheem/canonical-markers/crates/pep508-rs/src/marker/tree.rs#L1329).
- The `PubGrubSpecifier` type has been moved to the new `uv-pubgrub`
crate, shared by `pep508-rs` and `uv-resolver`. `pep508-rs` also depends
on the `pubgrub` crate for the `Range` type, we probably want to move
`pubgrub::Range` into a separate crate to break this, but I don't think
that should block this PR (cc @konstin).
There is still some remaining work here that I decided to leave for now
for the sake of unblocking some of the related work on the resolver.
- We still use `Option<MarkerTree>` throughout uv, which is unnecessary
now that `MarkerTree::TRUE` is canonical.
- The `MarkerTree` type is now interned globally and can potentially
implement `Copy`. However, it's unclear if we want to add more
information to marker trees that would make it `!Copy`. For example, we
may wish to attach extra and requires-python environment information to
avoid simplifying after construction.
- We don't currently combine `python_full_version` and `python_version`
markers.
- I also have not spent too much time investigating performance and
there is probably some low-hanging fruit. Many of the test cases I did
run actually saw large performance improvements due to the markers being
simplified internally, reducing the stress on the old `normalize`
routine, especially for the extremely large markers seen in
`transformers` and other projects.

## Summary
This PR adds a `DistExtension` field to some of our distribution types,
which requires that we validate that the file type is known and
supported when parsing (rather than when attempting to unzip). It
removes a bunch of extension parsing from the code too, in favor of
doing it once upfront.
Closes https://github.com/astral-sh/uv/issues/5858.
Currently, the entry for a package+version+source table is called
`distribution`. That is incorrect, the `sdist` and `wheel` fields inside
of that table are distributions, the table itself is for a package. We
also align ourselves closer with PEP 751.
I went through `lock.rs` and renamed all occurrences of "distribution"
that actually referred to a "package".
This change invalidates all existing lockfiles.
Bikeshedding: Do we call it `package` or `packages`? See also
https://github.com/python/peps/pull/3877
`package` is nice because it looks like a header:
```toml
[[package]]
name = "anyio"
version = "4.3.0"
source = { registry = "https://pypi.org/simple" }
dependencies = [
{ name = "idna" },
{ name = "sniffio" },
]
sdist = { url = "3970183622/anyio-4.3.0.tar.gz", hash = "sha256:f75253795a87df48568485fd18cdd2a3fa5c4f7c5be8e5e36637733fce06fed6", size = 159642 }
wheels = [
{ url = "2f20c40b45/anyio-4.3.0-py3-none-any.whl", hash = "sha256:048e05d0f6caeed70d731f3db756d35dcc1f35747c8c403364a8332c630441b8", size = 85584 },
]
```
`packages` is nice because the field is not a single entry, but a list.

## Summary
Very subtle bug. The scenario is as follows:
- We resolve: `elmer-circuitbuilder = { git =
"https://github.com/ElmerCSC/elmer_circuitbuilder.git" }`
- The user then changes the request to: `elmer-circuitbuilder = { git =
"https://github.com/ElmerCSC/elmer_circuitbuilder.git", rev =
"44d2f4b19d6837ea990c16f494bdf7543d57483d" }`
- When we go to re-lock, we note two facts:
1. The "default branch" resolves to
`44d2f4b19d6837ea990c16f494bdf7543d57483d`.
2. The metadata for `44d2f4b19d6837ea990c16f494bdf7543d57483d` is
(whatever we grab from the lockfile).
- In the resolver, we then ask for the metadata for
`44d2f4b19d6837ea990c16f494bdf7543d57483d`. It's already in the cache,
so we return it; thus, we never add the
`44d2f4b19d6837ea990c16f494bdf7543d57483d` ->
`44d2f4b19d6837ea990c16f494bdf7543d57483d` mapping to the Git resolver,
because we never have to resolve it.
This would apply for any case in which a requested tag or branch was
replaced by its precise SHA. Replacing with a different commit is fine.
It only applied to `tool.uv.sources`, and not PEP 508 URLs, because the
underlying issue is that we aren't consistent about "automatically"
extracting the precise commit from a Git reference.
Closes https://github.com/astral-sh/uv/issues/5860.
