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.

`uv tool upgrade` already respects version pins, but when a tool was
installed with an exact version the command quietly becomes a no-op even
though users expect it to upgrade the executable. This change tweaks the
upgrade flow to detect that situation by inspecting the stored receipt
and, whenever the tool stays pinned, emit a concise hint explaining why
the version didn’t move and how to reinstall without the pin.
The message still appears if the run only refreshed supporting packages,
so users aren’t misled by dependency churn that leaves the tool itself
untouched.
I also added an integration test for the scenario end to end by
installing `babel==2.6.0`, attempting an upgrade, and asserting that the
hint is shown alongside the dependency updates.
Closes https://github.com/astral-sh/uv/issues/16112
```
❯ cargo run -q cache clean
Cache is currently in-use, waiting for other uv processes to finish (use `--force` to override)
```
Otherwise, `-v` is required to see we're waiting on a lock.
I'd rather do this than elevate the exclusive lock log message to
something more verbose because this allows us to use a more specific
message as appropriate for the situation. We also previously reduced the
verbosity of arbitrary locks, e.g., see
https://github.com/astral-sh/uv/issues/7489

## Summary
We serialize the index to the lockfile without the username, so if we
compare based on `==` and the user _includes_ the username in their
`pyproject.toml`, the check will always fail.

Resolves https://github.com/astral-sh/uv/issues/16067
When we build the dependency graph we add an edge per `Requires-Dist`.
If a package publishes multiple marker-guarded requirements (like
pylint’s `dill>=…` for different Python versions), more than one marker
can evaluate to true at runtime, which gives us several edges pointing
to the same installed package node.
To avoid printing the package multiple times, we gather all edges
targeting that node, pass them through a `Cursor`, and aggregate their
requirement details before we print the dependency line. That
aggregation does two things:
1. If any edge carries a URL, we return that URL immediately.
2. Otherwise we merge all version specifiers into one canonical PEP 440
string.
I've added an integration test, namely `cargo test -p uv --test it
--features pypi -- no_duplicate_dependencies_with_markers` exercises the
new snapshot that installs pylint (with the real dill duplication
scenario present in the original issue) and asserts the tree output,
both with and without `--show-version-specifiers`, now shows a single
dill entry with the merged constraint.
## Summary
I don't think it's common for this to matter, but in theory at least
it's important that these are ordered by severity. Otherwise, e.g,
changing the pre-release mode (and then returning early) could mean we
retain the forks when we otherwise shouldn't.
## Summary
This argument has always existed for compatibility, but apparently we
don't respect it. I assume it was unintentionally dropped during a
refactor.

## 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.
## Summary
This PR enables users to mark a URL as an S3 endpoint, at which point uv
will sign requests to that URL by detecting credentials from the
standard AWS environment variables, configuration files, etc.
Signing is handled by the
[reqsign](https://docs.rs/reqsign/latest/reqsign/) crate, which we can
also use in the future to sign requests for other providers.
We're seeing reports of a regression from
https://github.com/astral-sh/uv/pull/15888 where `--no-cache` causes `uv
run` and `uvx` to fail to spawn a command.
The intent of this code was to allow destructive cache operations
_after_ we'd finished setting up the environment. However, it's unclear
to me that it's safe to run `uv cache clean` during a `uv run` operation
(e.g., `uv run --script` uses an environment in the cache) and, more
importantly, we cannot drop non-persistent caches (e.g., from
`--no-cache`) as they include the environment we're spawning the command
in.
Alternative to #15977 which retains release of the lock — we may want to
consider that approach still but this regression needs to be resolved
quickly.
Closes https://github.com/astral-sh/uv/issues/15989
Closes https://github.com/astral-sh/uv/issues/15987
Closes https://github.com/astral-sh/uv/issues/15967
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.

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
Currently, `uv cache clean` and `uv cache prune` can cause crashes in
other uv processes running in parallel by removing their in-use files.
We can solve this by using a shared (read) lock on the cache directory,
while the `uv cache` operations use an exclusive (write) lock. The
drawback is that this is always one extra lock, and that we assume that
all platforms support shared locks.
Once Rust 1.89 fulfills our N-2 policy, we can add support for these
methods in fs_err and switch to
https://doc.rust-lang.org/std/fs/struct.File.html#platform-specific-behavior-2.
