Resolves https://github.com/astral-sh/uv/issues/16496
This PR updates the resolver so `build-system` dependency failures
surface prerelease hints even when prerelease selection is fixed. When a
build dependency only has prerelease candidates, or the requested
version explicitly includes a prerelease marker, we now emit a tailored
hint explaining that build environments can’t auto-enable prereleases
and describing how to opt in.

## Summary
This PR adds an `exclude-dependencies` setting that allows users to omit
a dependency during resolution. It's effectively a formalized version of
the `flask ; python_version < '0'` hack that we've suggested to users in
various issues.
Closes#12616.
Provide a good error message when the discovered workspace members
mismatch with the locked workspace members in `uv export --frozen`,
instead of panicking.
Fixes#16406
Fixes#16340
## Summary
Some package registries (PyTorch, corporate PyPI mirrors) return `403
Forbidden` when a package is not found, instead of `404 Not Found`. The
previous error message incorrectly suggested this was always an
authentication issue, causing confusion for users.
This PR updates the error hint to clarify that a 403 error could
indicate either missing authentication credentials OR that the package
doesn't exist on the index.
## Test Plan
- Updated existing snapshot test in `crates/uv/tests/it/edit.rs` to
reflect the new error message
- The change is purely a message improvement with no behavioral changes
## Changes
### Before
hint: An index URL (https://example.com/simple) could not be queried due
to a lack of valid authentication credentials (403 Forbidden).
### After
hint: An index URL (https://example.com/simple) returned a 403 Forbidden
error. This could indicate missing authentication credentials, or the
package may not exist on this index.
## Files Changed
- `crates/uv-resolver/src/pubgrub/report.rs` - Updated error message
- `crates/uv/tests/it/edit.rs` - Updated snapshot test expectation

## Summary
fixes issue #15938
- show platform wheel hint with a concrete
`tool.uv.required-environments` example so users know how to configure
compatibility
- add `WheelTagHint::suggest_environment_marker` to pick a sensible
environment marker based on the available wheel tags
- update the `sync_required_environment_hint` integration snapshot to
expect the new multi-line hint
## Test Plan
cargo test --package uv --test it --
sync::sync_required_environment_hint
## Summary
If you provide `--refresh` to `uv lock`, we'll now always resolve (even
though it might return the same result). This is also robust to
`--locked` such that `--refresh --locked` will only fail if the lockfile
changes.
Closes https://github.com/astral-sh/uv/issues/15997.
Add an incompatibility that lets pubgrub skip of marker packages when
the base package already has an incompatible version to improve the
error messages (https://github.com/astral-sh/uv/issues/15199).
The change is also a small perf improvement. Overall this should be able
to improve performance in slow cases by avoiding trying proxy package
versions that are impossible anyway, for a (ideally very small cost) for
tracking the additional incompatibility and tracking the base package
for each proxy package.

This implementation is the basic version: When we see a proxy
`foo{...}>=x,<y` we add a dependency edge `foo{...}>=x,<y` ->
`foo>=x,<y`. There are several way to extend this, which likely help
more with performance than with error messages.
One idea is that if we see `foo{...}>=x,<y` but we already made a
selection for `foo==z` outside that range, we can insert a dependency
`foo{...}!=z` -> `foo!=z`. This avoids trying any version of the proxy
package except the version that matches our previous selection.
Another is that if we see a dependency `foo>=x,<y`, we also add
`foo{...}>=x,y` -> `foo>=x,<y`. This allows backtracking beyond `foo`
immediately if all version of `foo{...}>=x,<y` are incompatible, since
`foo{...}>=x,<y` incompatible -> `foo>=x,<y` incompatible -> the package
that depended of `foo>=x,<y` is incompatible.
The cost for each of these operations is tracking an additional
incompatibility per virtual package. An alternative approach is to only
add the incompatibility lazily, only when we've tried several version of
the virtual package already. This needs to be weighed of with the better
error messages that the incompatibility gives, we unfortunately have
only few large reference examples.
Requires https://github.com/astral-sh/pubgrub/pull/45
Closes https://github.com/astral-sh/uv/issues/15199
## Summary
Fixes issue #15190 where `uv sync --no-sources` fails to switch from
editable to registry package installations. The problem occurred because
the installer's satisfaction check didn't consider the `--no-sources`
flag when determining if an existing editable installation was
compatible with a registry requirement.
## Solution
Modified `RequirementSatisfaction::check()` to reject non-registry
installations when `SourceStrategy::Disabled` and the requirement is
from registry. Added `SourceStrategy` parameter threading through the
entire call chain from commands to the satisfaction check to ensure
consistent behavior between `uv sync --no-sources` and `uv pip install
--no-sources`.

## Summary
In the process of making a different change, I noticed that we parse
this during source discovery, throw it away, then parse it again later.
## Summary
Right now, we only list changes if the _version_ differs. This PR takes
the SHA into account. We may want to list changes to _any_ sources, but
that gets more complicated (e.g., if the user swaps the index URL, we'd
have to show _all_ changes to the index URL).
Closes#15810.
## Summary
We support `--no-editable` on the CLI, but now that workspace members
and path dependencies can be marked as `editable = false`, I think it
makes sense for `--editable` to override that.
## Summary
This ended up being a bit more complex, similar to `package = false`,
because we need to understand the editable status _globally_ across the
workspace based on the packages that depend on it.
Closes https://github.com/astral-sh/uv/issues/15686.
## Summary
This PR allows pyx to send down hashes for zstandard-compressed
tarballs. If the hash is present, then the file is assumed to be present
at `${wheel_url}.tar.zst`, similar in design to PEP 658
`${wheel_metadata}.metadata` files. The intent here is that the index
must include the wheel (to support all clients and support
random-access), but can optionally include a zstandard-compressed
version alongside it.
## Summary
This PR adds support for the `application/vnd.pyx.simple.v1` content
type, similar to `application/vnd.pypi.simple.v1` with the exception
that it can also include core metadata for package-versions directly.
In https://github.com/astral-sh/uv/issues/11636, we're getting reports
for installation flakes that report an invalid package format for what
appears to be a network problem. Since we're cutting the error reporting
to the first error message in the chain, we're not reporting the actual
network error underneath it.
This PR displays the whole error chain for invalid package format
errors, so we can debug and eventually catch-and-retry
https://github.com/astral-sh/uv/issues/11636.

## Summary
Adds the enhancement proposed in #15470. Each package in the dependency
tree now shows its compressed wheel file size, reading the wheel sizes
directly from the lockfile (uv.lock). Doesn't break existing tree
formatting or options. If no wheel size is available, nothing is added.
Now, developers can identify large packages in their dependency tree.
The tree still shows extras exactly as before, and then appends a size
for the package.

## Summary
We've received several requests to validate that installed wheels match
the current Python platform. This isn't _super_ common, since it
requires that your platform changes in some meaningful way (e.g., you
switch from x86 to ARM), though in practice, it sounds like it _can_
happen in HPC environments. This seems like a good thing to do
regardless, so we now validate that the tags (as recoded in `WHEEL`) are
consistent with the current platform during installs.
Closes https://github.com/astral-sh/uv/issues/15035.

## Summary
<!-- What's the purpose of the change? What does it do, and why? -->
Closes#14866. Adds a `no-install-local` flag to the sync and export
commands that excludes locally defined packages from being installed.
This helps with if you're caching your virtual environment. You can
exclude local packages since they're more likely to change between
builds.
## Test Plan
snapshot test: `sync::no_install_local`
CI
## Notes
I made an `InstallOptions` struct to avoid a crate isolation issue I was
running into while implementing.
Thanks for maintaining this project!
## Summary
Packages like `triton` should come from the PyTorch index, but they
don't actually vary across (e.g.) the `cu128` or `cu129` indexes.
Closes https://github.com/astral-sh/uv/issues/15446.
## Test Plan
Validate that the following pins to `cu128`, rather than `cpu`:
```
echo "vllm\ntorch==2.7.1+cu128" | cargo run pip compile --torch-backend=auto --extra-index-url https://wheels.vllm.ai/b2f6c247a9b84556a8ea0e75bb4a2db765ff3315 - --python-platform linux --python-version 3.13 -v
```
Revives https://github.com/astral-sh/uv/pull/9130
Previously, we allowed scoping conflicting extras or groups to specific
packages, e.g. ,`{ package = "foo", extra = "bar" }` for a conflict in
`foo[bar]`. Now, we allow dropping the `extra` or `group` bit and using
`{ package = "foo" }` directly which declares a conflict with `foo`'s
production dependencies.
This means you can declare conflicts between workspace members, e.g.:
```
[tool.uv]
conflicts = [[{ package = "foo" }, { package = "bar" }]]
```
would not allow `foo` and `bar` to be installed at the same time.
Similarly, a conflict can be declared between a package and a group:
```
[tool.uv]
conflicts = [[{ package = "foo" }, { group = "lint" }]]
```
which would mean, e.g., that `--only-group lint` would be required for
the invocation.
As with our existing support for conflicting extras, there are
edge-cases here where the resolver will _not_ fail even if there are
conflicts that render a particular install target unusable. There's test
coverage for some of these. We'll still error at install-time when the
conflicting groups are selected. Due to the likelihood of bugs in this
feature, I've marked it as a preview feature.
I would not recommend reading the commits as there's some slop from not
wanting to rebase Andrew's branch.

Previously, `simplify_conflict_markers` assumed that it can remove all
conflict set together, when we need to look at each conflict set
individually. Specifically, `(platform_machine == 'x86_64' and extra ==
'extra-5-foo-b') or extra == 'extra-5-foo-a'` can't be reduced
`platform_machine == 'x86_64'` only because it reduces to true when both
conflict extras are activated.
This case applied in https://github.com/astral-sh/uv/issues/14805, where
a jax 0.5.3 version was used for `platform_machine != 'aarch64' or
sys_platform != 'linux'` and the conflict extra `cu128`, but jax 0.7.0
for the conflict extra `cpu`.
Only removing the faulty inference regresses lockfiles to much more
verbose markers. To balance the much more conservative inference, I
added `unify_inference_sets` to simplify cases where all conflict
branches reduce to the same marker.
This still regresses some markers. For example `sys_platform == 'win32'`
regresses to `sys_platform == 'win32' or (extra == 'extra-3-pkg-x1' and
extra == 'extra-3-pkg-x2')` in `extra_inferences`, even through x1 and
x2 conflict and the second conjunction could be simplified away.
Fixes https://github.com/astral-sh/uv/issues/14805
## Summary
Make the use of `Self` consistent. Mostly done by running `cargo clippy
--fix -- -A clippy::all -W clippy::use_self`.
## Test Plan
<!-- How was it tested? -->
No need.
Apply fixes for some `cargo check` and `cargo clippy` lints that are on
in nightly Rust.
The following command now passes, the blanket allows had to many
false-positives:
```
cargo +nightly clippy -- -A clippy::doc_markdown -A mismatched_lifetime_syntaxes -A clippy::explicit_deref_methods
```
`cargo +nightly check -- -A mismatched_lifetime_syntaxes` now passes
without warnings.
## Summary
We often match on `ErrorKind` to figure out how to handle an error
(e.g., to treat a 404 as "Not found" rather than aborting the program).
Unfortunately, if we retry, we wrap the error in a new kind that
includes the retry count. This PR adds an unwrapping mechanism to ensure
that callers always look at the underlying error.
Closes https://github.com/astral-sh/uv/issues/14941.
Closes https://github.com/astral-sh/uv/issues/14989.
## Summary
This just looks like an oversight. We weren't including hashes from
local Simple API indexes if a package had both a wheel and a source
distribution.
Closes https://github.com/astral-sh/uv/issues/14883
Adds `exclude-newer-package = { package = timestamp, ... } ` and
`--exclude-newer-package package=timestamp`. These take precedence over
`exclude-newer` for a given package.
This does need to be serialized to the lockfile, so the revision is
bumped to 3. I tested a previous version and we can read a lockfile with
this information just fine.
Closes https://github.com/astral-sh/uv/issues/14394
`Candidate` has an optional field `prioritized`, which was mostly
redundant with `CandidateDist`. Specifically, it was only `None`, if
`CandidateDist` was `Installed`. This commit removes this duplication.
## Summary
This is an alternative to #14003 that takes advantage of the fact that
we already validate that the requirements are up-to-date when validating
the lockfile, and the requirements for pinned requirements include the
index itself -- so rather than collecting all the explicit indexes
upfront, we can just add them to the available list as we iterate over
the lockfile's dependency graph.
This gets all the tests passing from that PR, but with ~no performance
impact and a much less invasive change. It also gets the "circular
dependency" test passing, which is marked with a TODO in that PR.
Closes https://github.com/astral-sh/uv/issues/11419.
## Summary
This PR adds derivation chain for another class of resolver failures.
For example, if we encounter a transitive URL dependency, we now tell
the user which package included it, and the full derivation chain:
```
× Failed to resolve dependencies for `foo` (v0.1.0)
╰─▶ Package `flask` was included as a URL dependency. URL dependencies must be
expressed as direct requirements or constraints. Consider adding `flask @
9d4508e893/flask-3.1.1-py3-none-any.whl`
to your dependencies or constraints file.
help: `foo` (v0.1.0) was included because `baz` (v0.1.0) depends on `foo`
```
Closes#14795.
We currently have two marker keys that a list, `extras` and
`dependency_groups`, both from PEP 751. With the variants PEP, we will
add three more. This change is broken out of the wheel variants PR to
introduce generic marker list support, plus a change to use
`ContainerOperator` in more places.
## Summary
We don't yet support writing these, but we can at least read them
(which, e.g., allows you to install PDM-exported `pylock.toml` files
with uv, since PDM _always_ writes a default group).
Closes#14740.
