When a process is running and another calls `uv cache clean` or `uv
cache prune` we currently deadlock - sometimes until the CI timeout
(https://github.com/astral-sh/setup-uv/issues/588). To avoid this, we
add a default 5 min timeout waiting for a lock. 5 min balances allowing
in-progress builds to finish, especially with larger native
dependencies, while also giving timely errors for deadlocks on (remote)
systems.
Commit 1 is a refactoring.
This branch also fixes a problem with the logging where acquired and
released resources currently mismatch:
```
DEBUG Acquired lock for `https://github.com/tqdm/tqdm`
DEBUG Using existing Git source `https://github.com/tqdm/tqdm`
DEBUG Released lock at `C:\Users\Konsti\AppData\Local\uv\cache\git-v0\locks\16bb813afef8edd2`
```
This was discovered by https://github.com/astral-sh/uv/pull/16074, where
the wrong tag now fails the Pyston integration test.
I'm not sure what the exact schema of the cache tag is, but since the
project is dead, I don't expect any new non-matching versions to follow.
## Summary
* Updates existing references to use EnvVars where usage was missing.
* Adds missing entries to env var usages, e.g. new env var declarations
in uv-trampoline, tests, etc.
* Note: this doesn't affect trampoline sizes as the end result is the
same
* Fixes versioning of `UV_HIDE_BUILD_OUTPUT`.
## Test Plan
Existing Tests. Compiled the trampolines locally to verify zero changes
(size, binary).
## Question
Will this complicate the crates publishing release process? I'm not
certain yet if it will be an issue for uv-trampoline (non-workspace
member) to reference a uv workspace member from a bump & release
perspective wrt lock files. If so, I'll revert the uv-trampoline changes
but keep the others.
Part of https://github.com/astral-sh/uv/issues/4392
We shouldn't link to PyPI, and dropping the workspace-level
documentation link should mean that we get the auto-generated `docs.rs`
links.

This PR detects managed prerelease interpreters during discovery and
warns when a matching stable build is available, wiring the new helper
into `PythonInstallation::find`, `find_best`, and `find_or_download`.
Resolves https://github.com/astral-sh/uv/issues/16295
This PR updates the Conda base-environment heuristic to recognize
Pixi-managed environments by checking for the `conda-meta/pixi` marker
file. Pixi default environments now resolve as isolated child
environments instead of system installations, restoring the expected uv
pip behavior without the `--system` flag.
`.rsrc` is the idiomatic way of storing metadata and non-code resources
in PE
binaries. This should make the resulting binaries more robust as they
are no longer
dependent on the exact location of a certain magic number.
Addresses: #15022
## Test Plan
Existing integration test for `uv-trampoline-builder` + addition to
ensure robustness
to code signing.

When `--system` is used, the debug log now reports interpreter discovery
sources in the same order they are probed, prioritising the PATH ahead
of managed installs on every platform. I also added a few unit tests
that use `DiscoveryPreferences::sources`, ensuring the log strings stay
aligned with the actual discovery sequence for both System and
OnlySystem preferences.
Cargo is currently recompiling uv-python on every invocation because the
minified JSON output file is getting a mod time newer than the last run.
Instead, set the mod time of the output file to the same as the input
file.
I think this is ostensively breaking, though I think the impact would be
small given this will go out in 0.9.1 and should only affect people
using pre-release Python versions.
When `3.14.0` is requested (opposed to `3.14`), we treat this as a
request for a final / stable version and ignore pre-releases.
I think this is a fairly clean way to allow users to explicitly request
the stable version.
Closes https://github.com/astral-sh/uv/issues/16175
Follows #16208
Pick up python-build-standalone tag 20251007 to add 3.14.0 final
and 3.13.8, and adjust tests.
Also, fix matching version requests with prereleases: `uvx
python@3.14.0rc3` should not be satisfied by 3.14.0 final.

The `uv-python` crate reads the checked-in download metadata to write
out a minified version to be statically included into the binary.
Sometimes, the resulting `download-metadata-minified.json` can go
missing, such as when `uv` is installed via `cargo` as a git source, and
there is an update; `cargo` will do a hard reset on the git repo it
stores in the cache, causing it to be deleted. In these instances, the
`uv-python` crate does not currently re-run its build script, because as
it happens, there was no change to the `download-metadata.json` since it
was last compiled. This causes a build error like:

error: could not compile `uv-python` (lib) due to 1 previous error
error: failed to compile `uv v0.8.24 (https://github.com/astral-sh/uv?tag=0.8.24#252f8873)`, intermediate artifacts can be found at `/home/skhawtho/.cache/cargo`.

```
This fixes the issue by also adding a `rerun-if-changed` on the
resulting minified JSON file.
Separately, this revision also changes the output directory of the
minified file to the build script's output directory via the `OUT_DIR`
environment variable, so as not to pollute the source code.
Turns out if the minor versions matched we returned false from
`is_upgrade_of` instead of continuing to compare prerelease versions.
Closes#15955.
Note: test cases were initially generated by Claude - I tried making
them shorter.
