## Summary
This PR reverts https://github.com/astral-sh/uv/pull/10441 and applies a
different fix for https://github.com/astral-sh/uv/issues/10425.
In #10441, I changed prioritization to visit proxies eagerly. I think
this is actually wrong, since it means we prioritize proxy packages
above _everything_ else. And while a proxy only depends on itself, it
does mean we're selecting a _version_ for the proxy package earlier than
anything else. So, if you look at #10828, we end up choosing a version
for `async-timeout` before we choose a version for `langchain`, despite
the latter being a first-party dependency. (`async-timeout` has a marker
on it, so it has a proxy package, so we solve for it first.)
To fix#10425, we instead need to make sure we visit proxies in the
order we see them. I think the virtual tiebreaker for proxies is
reversed? We want to visit the package we see first, first.
So, in short: this reverts #10441, then corrects the ordering for
visiting proxies.
Closes https://github.com/astral-sh/uv/issues/10828.
## Summary
The linked issue actually isn't a bug on main anymore, but it does
require us to take the "slow" path, since setuptools seems to reorder
the extras. This PR adds another normalization step which lets us take
the fast path: https://github.com/astral-sh/uv/issues/10855.
## Summary
For example: in the linked issue, the user has a symlink at
`pyproject.toml`. The GitHub CDN doesn't give us any way to determine
whether a file is a symlink, so we should just log the error and move on
to the slow path.
Closes https://github.com/astral-sh/uv/issues/10857
## Summary
I noticed that we're only handling `Error::WheelMetadataNameMismatch`
here; but `Error::WheelMetadataVersionMismatch` should also be treated
as non-fatal.
## Summary
Relates to #10273.
This doesn't solve what is highlighted in
https://github.com/astral-sh/uv/issues/10273#issuecomment-2569515066,
but I believe this is still an improvement for users not setting
`upgrade = true` in `[tool.uv]`.
## Test Plan
Ran commands locally:
```shell
$ cargo run --quiet -- lock --locked --upgrade
error: the argument '--check' cannot be used with '--upgrade'
Usage: uv lock --check
For more information, try '--help'.
```
from https://github.com/astral-sh/uv/issues/9742
```
❯ cargo run -q --bin uvx
Provide a command to run with `uvx <command>`.
The following tools are installed:
- ansible-core v2.17.5
- black v24.10.0
- rooster-blue v0.0.0
See `uvx --help` for more information.
❯ rm target/debug/uv
❯ cargo run -q --bin uvx
error: Could not find the `uv` binary at /Users/zb/workspace/uv/target/debug/uv
```

In the interest of expanding these tests and debugging weird behaviors,
I've moved the smoke tests out of the `cargo test` job and into
dedicated `smoke test` jobs. We explicitly build `uvx` in the `build
binary` jobs instead of relying on the implicit build for the test run.
I also added a `uvx` test case to the smoke tests: `uvx ruff --version`
Previously, these errors would only be visible in the debug logs as
"Skipping bad interpreter ..." which can lead us to making some
ridiculous claims like "There is no virtual environment" or "Python is
not installed" when really we just failed to query the interpreter for
some reason.
We show the first error, sort of arbitrarily — but I think it matches
user expectation, i.e., this would be the first Python on your PATH.
Related to #10713
## 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.
When support for conflicting extras/groups was initially added, I
stopped short of including the conflict markers in uv's "fork markers"
in the lock file. That is, the fork markers are markers that indicate
the different splits uv took during resolution, which we record, I
believe, to avoid spurious updates to the lock file as a result of
using them as preferences.
One interesting result of omitting the conflict markers from the fork
markers is that sometimes this would result in duplicate markers. In
response, I wrote a function that stripped off the conflict markers and
deduplicated the remainder. My thinking at the time was that it wasn't
clear whether we needed to keep conflict markers around.
It looks like #10783 demonstrates a case where we do, seemingly, need
them. Namely, it's a case where after stripping conflict markers, you
don't end up with duplicate markers, but you do end up with overlapping
markers. Overlapping fork markers are bad juju for the same reason that
overlapping resolver forks are bad juju: you can end up with multiple
versions of the same package in the same environment.
I don't know how to fix overlapping markers without just including the
conflict markers. So that's what this PR does. Because of this, there
will be some churn in lock files, but this only applies to projects that
define conflicting extras.
This PR includes a regression test from #10783. I also manually tried
the original reproduction in #10772 (where adding `numpy<2` caused `uv
sync` to fail), and things worked.
Fixes#10772, Fixes#10783
## Summary
The docs did mention that you could set the `UV_PROJECT_ENVIRONMENT`
variable to point Uv to use the system Python environment (e.g. for use
in CI or Docker), but it did not document _how_.

## Summary
Replacing the large `pybabel` in tests with
[`executable-application`](https://pypi.org/project/executable-application/)
(1.7 KB).
We may want a separate test package with an executable that _does_ match
the name? This one intentionally does _not_. It would make it much
easier for us to rewrite the other tests in bulk, since we can do a
find-and-replace on `black`, etc.
Closes https://github.com/astral-sh/uv/issues/10646.
Demo at https://github.com/zanieb/uv/issues
I think the next steps are to
- Move the "Build failures" document to a dedicated "Troubleshooting"
section
- Add more documentation on how to create an MRE
- Add more troubleshooting pages
## Summary
rooster should pick those up, but those 2 references were added to 0.5.8
while a 0.5.9 was already released
(f5add0ca5e),
so they never got bumped automatically.
I've searched for other cases like this in the documentation on other
versions, just in case, and it seems that this is the only case.
## Summary
This is a smaller alternative to #10794. If the `Requires-Dist` that we
extract statically doesn't match the lockfile metadata, we now go back
to the distribution database to double-check. Checking the
`Requires-Dist` is itself very cheap, so in the worst case, we're just
paying the same cost as prior to this optimization.
Closes https://github.com/astral-sh/uv/issues/10776.
## Summary
When resolving Git metadata, we may be able to fetch the metadata from
GitHub directly in some cases. This is _way_ faster, since we don't need
to perform many Git operations and, in particular, don't need to clone
the repo.
This only works in the following cases:
- The Git repository is public. Otherwise, I believe you need an access
token, which we don't have.
- The `pyproject.toml` has static metadata.
- The `pyproject.toml` has no `tool.uv.sources`. Otherwise, we need to
lower them... And, if there are any paths or workspace sources, that
requires an install path (i.e., we need the content on-disk).
- The project is in the repo root. If it's in a subdirectory, it could
be a workspace member. And if it's a workspace member, there could be
sources defined in the workspace root. But we can't know without
fetching the workspace root -- and we need the workspace in order to
find the root...
Closes#10568.
## Summary
These are very similar to (and computed in the same way as) the hints we
should during a failed resolution, but for install-time.
Closes#10635.
## Test Plan
As an example, when installing PyTorch on macOS with Python 3.13 (wheels
exist for Linux):
```
error: Distribution `torch==2.5.1 @ registry+https://pypi.org/simple` can't be installed because it doesn't have a source distribution or wheel for the current platform
hint: You're on macOS (`macosx_14_0_arm64`), but `torch` (v2.5.1) only has wheels for the following platform: `manylinux1_x86_64`
```
See https://github.com/astral-sh/uv/issues/4204 for motivation
This doesn't really reach the user experience I'd expect — i.e., we end
up saying a virtual environment "does not exist" which is a little
silly. However, I think improving the error messaging on interpreter
queries in general should be solved separately. I did one small
"general" change in
89e11d0222
— otherwise we don't show the message at all.

## Summary
The fix I shipped in https://github.com/astral-sh/uv/pull/10690
regressed an important case. If we solve a PyPI branch before a PyTorch
branch, we'll end up respecting the preference, and choosing `2.2.2`
instead of `2.2.2+cpu`.
This PR goes back to ignoring preferences that don't map to the current
index. However, to solve https://github.com/astral-sh/uv/issues/10383,
we need to special-case `requirements.txt`, which can't provide explicit
indexes. So, if a preference comes from `requirements.txt`, we still
respect it.
Closes https://github.com/astral-sh/uv/issues/10772.
