First commit is refactoring, second commit is the actual change.
The h2 errors, a specific type nested in reqwest errors, all look like
they shouldn't happen in regular operations and should be retried. This
covers all `io::Error`s going through h2 (i.e., only HTTP 2
connections).
Fixes https://github.com/astral-sh/uv/issues/15916
## Summary
As new environment variables get introduced (e.g. `UV_EDITABLE`) I
thought it would useful to start tracking which release they were
introduced. I think its a common workflow to navigate to the [env var
documentation](https://docs.astral.sh/uv/reference/environment) to know
what the env var for something is but then end up in a situation where
one is using an environment variable with the wrong version of uv and
not notice immediately that its not compatible and therefore ignored.
## Test Plan
Existing tests.
The versions in `since` have all been manually reviewed to the best of
my ability for correctness.

-->
## Summary
<!-- What's the purpose of the change? What does it do, and why? -->
This pull request enables the `--directory` option to accept environment
variable: `UV_DIRECTORY`
### Motivation
Currently, the `--project` option already supports environment
variables, but --directory does not.
The motivation for this change is the same as for the --project option.
When using this option, it’s likely that the project root and the
directory containing the uv project differ. In such cases, allowing
environment variables makes it easier to avoid repeatedly specifying the
directory in commands or task runners.
### Other PRs
- PR for create `--project` option:
https://github.com/astral-sh/uv/pull/12327
## Test Plan
<!-- How was it tested? -->
### no auto testing
As with the --project option, no auto tests are included for this
change.
This is because the implementation relies on Clap’s built-in attribute
functionality, and testing such behavior would effectively mean testing
a third-party crate, which would be redundant.
As long as the compiler accepts it, things should work as expected.
### testing manually
i tested manually like [previous pull
request](https://github.com/astral-sh/uv/pull/12327)
```shell
$ cargo build --locked

Hey devs, great tool as always, you're doing amazing work.
## Summary
<!-- What's the purpose of the change? What does it do, and why? -->
Adds the following fields to the `[package]` table of `Cargo.toml` files
where they were missing:
```toml
rust-version = { workspace = true }
homepage = { workspace = true }
documentation = { workspace = true }
repository = { workspace = true }
authors = { workspace = true }
license = { workspace = true }
```
Most crates already had these fields, this just aligns the rest for
consistency.
This also resolves the warnings from `cargo-deny` when using `uv` crates
as dependencies in Pixi.
## Test Plan
No tests needed, this only updates metadata.
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`.
To reuse those artifacts with a future compilation, set the environment variable `CARGO_TARGET_DIR` to that path.
```
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

<!-- What's the purpose of the change? What does it do, and why? -->
Fixes a part of #14720
Add `TRACING_DURATIONS_FILE` to EnvironmentOptions.
## Test Plan
<!-- How was it tested? -->
## 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.
Closes https://github.com/astral-sh/uv/issues/16076.
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.
