Adds a default plain text storage mechanism to `uv auth`.
While we'd prefer to use the system store, the "native" keyring support
is experimental still and I don't want to ship an unusable interface.
@geofft also suggested that the story for secure credential storage is
much weaker on Linux than macOS and Windows and felt this approach would
be needed regardless.
We'll switch over to using the native keyring by default in the future.
On Linux, we can now fallback to a plaintext store the secret store is
not configured, which is a nice property.
Right now, we store credentials in a TOML file in the uv state
directory. I expect to also read from the uv config directory in the
future, but we don't need it immediately.
Picks up the work from
- #14559
- https://github.com/astral-sh/uv/pull/14896
There are some high-level changes from those pull requests
1. We do not stash seen credentials in the keyring automatically
2. We use `auth login` and `auth logout` (for future consistency)
3. We add a `token` command for showing the credential that will be used
As well as many smaller changes to API, messaging, testing, etc.

## Summary
We (and I'm sure many others) are currently doing a lot of RISC-V work
in QEMU. It is possible to significantly improve the speed of
Python-related builds by taking care of the environment setup using an
AMD64 `uv` binary (bypassing binfmt/qemu-system emulation).
Some approx numbers from local testing in riscv64 Ubuntu in QEMU:
| Resolver arch | Command | Time |
| --- | --- | --- |
| riscv64 | `pip install --upgrade --break-system-packages
--index-url=https://gitlab.com/api/v4/projects/riseproject%2Fpython%2Fwheel_builder/packages/pypi/simple
openai-harmony` | 15s |
| riscv64 | `uv pip install --upgrade --system --break-system-packages
--index-url=https://gitlab.com/api/v4/projects/riseproject%2Fpython%2Fwheel_builder/packages/pypi/simple
openai-harmony` | 5s |
| amd64 | `uv pip install --python-platform=riscv64-unknown-linux
--upgrade --system --break-system-packages
--index-url=https://gitlab.com/api/v4/projects/riseproject%2Fpython%2Fwheel_builder/packages/pypi/simple
openai-harmony` | 4s |
The numbers from some larger internal packages with deeper dependency
trees are much more pronounced - 3m6 vs 43s vs 8s, in one example.
Manylinux 2.39 is specified, as it's the first (only?) RISC-V manylinux
## Test Plan
Locally, in QEMU.
`$ docker run --platform linux/riscv64 -it ubuntu:latest`, get amd64
libc into LD_LIBRARY_PATH, tests as above
## Summary
Override `sys.base_prefix` when performing `python_module` tests, in
order to prevent `find_uv_bin()` from finding `uv` installed alongside
system Python, and therefore fix test failures on Gentoo.
Fixes#15368
## Test Plan
```
cargo test --profile=fast-build --features git --features pypi --features python --no-default-features --test it python_module
```

When migrating from the `reqwest_retry` crate, we want to ensure that
the status codes we retry stay the same. This also helps us to
intentionally migrate to a different list later, by enumerating the list
of status codes that are retried.
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
This was fixed in https://github.com/astral-sh/uv/pull/15161, then
reverted as it regressed the error handling. I've re-applied the change
here, but moved the error handling to the runtime, rather than
parse-time. I think this is slightly worse in that we no longer include
the originating source code snippet, but it at least gives us the
expected behavior :(
Closes https://github.com/astral-sh/uv/issues/15124.
When there is an error during the streaming download and unpack for
Python interpreter and bin installs, we would previously fail, causing a
lot of CI flakes on GitHub Actions.
The problem was that the error is not one of the extended IO errors we
were previously handling, but a regular reqwest error, nested below
layers of errors of other crates processing the stream, including some
IO errors. We now handle nested reqwest errors, too.
This surfaced another problem: Our manual retry loop couldn't inform the
retry middleware that it already performed the limit of retries, and
that the middleware should not retry anymore. While too many retries are
more a problem for debugging than for the user, this causes confusing
error output. To work around this, we disable the retries in the client
and handle all retry errors in our loop.
Fixes https://github.com/astral-sh/uv/issues/14171

Alternative to #15105
Instead of building a `BaseClientBuilder` from `NetworkSettings` each
time we need a client, we instead build a single `BaseClientBuilder` and
pass it around. The `RegistryClientBuilder` then uses
`BaseClientBuilder` exclusively for configuration. This removes a chunk
of copy-and-paste code, and also moves the fallible `retries_from_env`
into a single place
Borrow vs. clone is mostly ad-hoc, we can change it in either direction
if it matters.
Closes#15105
https://github.com/astral-sh/uv/issues/11836#issuecomment-3022735011 was
caused by a missing `cache_index_credentials()` call. This call was
always preceding a registry client builder. We can improve this
situation by caching index credentials in the registry client builder.

## 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
`CLICOLOR_FORCE` changes the output of underlying build commands, which
messes with wrapper tools trying to parse their output.
Closes#12564, closes#15415.
Add support for `RUST_LOG` to the uv build backend. While we were
previously using logging statements in the uv build backend, they could
only be shown when when using the direct build fast path through uv, as
there was no tracing subscriber to write log messages out. This means no
debug logging when using the build backend through pip, `python -m
build`, an incompatible version of uv, or any other build frontend; No
option to figure why includes and excludes behave the way they do.
This PR closes this gap by adding a tracing subscriber. The only option
to enable it is `RUST_LOG`, as we don't have a CLI. The formatting style
is the same as for uv, and color is also support in the same way, albeit
only through anstream's support for TTYs and environment variables. We
recommend only `RUST_LOG=uv=debug` and `RUST_LOG=uv=verbose` in the
docs, but this can be used to debug into crates such as `glob`, too.

Fixes#12723
Allows pinning the Python build version via environment variables, e.g.,
`UV_PYTHON_CPYTHON_BUILD=...`. Each variable is implementation specific,
because they use different versioning schemes.
Updates the Python download metadata to include a `build` string, so we
can filter downloads by the pin. Writes the build version to a file in
the managed install, e.g., `cpython-3.10.18-macos-aarch64-none/BUILD`,
so we can filter installed versions by the pin.
Some important follow-up here:
- Include the build version in not found errors (when pinned)
- Automatically use a remote list of Python downloads to satisfy build
versions not present in the latest embedded download metadata
Some less important follow-ups to consider:
- Allow using ranges for build version pins
## 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
After chatting with the PyTorch team, it looks like some number of
wheels were accidentally uploaded with
`no-cache,no-store,must-revalidate` due to
https://github.com/pytorch/pytorch/pull/149218. They're going to correct
this for the respective wheels. I've encouraged them to set an immutable
caching header for these files, and it might happen. But even if this
isn't set, by default we only allow these wheels to be cached for 600s,
since the other wheels don't include a `Cache-Control` header at all
(but do include a `Last-Modified`, so we cache based on our heuristic:
`Freshness lifetime heuristically assumed because of presence of
last-modified header: 600s`). This probably leads to tons of unnecessary
downloads for users over time. Andrey from the PyTorch team agreed that
we should do this.
Closes https://github.com/astral-sh/uv/issues/15480.
## Summary
This is causing some cyclic dependencies issues for me, because these
can be used in virtually _any_ crate (like `uv-install-wheel`), which
then means that all of `uv-configuration` becomes a dependency, etc. I
think this should be a leaf crate so that we can safely depend on it
anywhere.

## 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
There isn't any risk here, and we have reports of at least one zip file
with more than one (but fewer than, e.g., 10) null bytes.
Closes https://github.com/astral-sh/uv/issues/15451.
## 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
```
## Summary
After #15395, I realized that we didn't actually need a separate struct
for this since we now pass it around as an `Option`. (The key change
from #15395 is that when combining, we treat the options as a single
unit.)
## Summary
`match-runtime` can be explicitly specified, and if it's `false` it
should behave the same way as if it's omitted.
## Test Plan
Added snapshot test
We should not unnecessarily leak memory. Instead, we follow the general
patterns and use `Cow` for strings that can be from either a static or a
dynamic source.
## Summary
Right now, if you put `upgrade = false` in a `uv.toml`, then pass
`--upgrade-package numpy` on the CLI, we won't upgrade NumPy. This PR
fixes that interaction by ensuring that when we "combine", we look at
those arguments holistically (i.e., we bundle `upgrade` and
`upgrade-package` into a single struct, which then goes through the
`.combine` logic), rather than combining `upgrade` and `upgrade-package`
independently.
If approved, I then need to add the same thing for `no-build-isolation`,
`reinstall`, `no-build`, and `no-binary`.

## Summary
The PyTorch team publishes ARM Linux wheels for `triton` to the PyTorch
index, which aren't available on PyPI.
## Test Plan
```
echo "torch" | cargo run pip compile - --torch-backend=cu128 --python-platform aarch64-unknown-linux-gnu --python-version 3.13
```
Previously failed because it couldn't find a compatible `triton` wheel.
As a frontend to Ruff's formatter.
There are some interesting choices here, some of which may just be
temporary:
1. We pin a default version of Ruff, so `uv format` is stable for a
given uv version
2. We install Ruff from GitHub instead of PyPI, which means we don't
need a Python interpreter or environment
3. We do not read the Ruff version from the dependency tree
See https://github.com/astral-sh/ruff/pull/19665 for a prototype of the
LSP integration.

Unpack the wheel
```
uvx wheel unpack dist/*.whl

Before this change, it will fail with a hash mismatch. I could confirm
with a local build that now the wheel can be unpacked with the `wheel`
command. While I don't enable hash checking when syncing, presumably it
would also currently fail.

I've written a reasonably-long comment to explain what's going on here.
We should fix this, but it's better to continue using a
potentially-stale distribution than to panic.

Venvs should not be in source distributions, and on Unix, we now reject
them for having a link outside the source directory. This PR adds a hint
for that since users were confused (#15096).
In the process, we're differentiating IO errors for format error for
uncompression generally.
Fixes#15096
## Summary
Closes#15355
This PR adds a fallback mechanism to `Shell::from_env()` that inspects
the parent process when shell environment variables are not available on
Unix-like systems.
Currently, `uv tool update-shell` fails with "the current shell could
not be determined" when environment variables like `ZSH_VERSION`,
`BASH_VERSION`, or `SHELL` are not exported. This commonly occurs in
automated environments such as GitHub Actions runners.
The fallback approach:
1. Uses `nix::unistd::getppid()` to get the parent process ID
2. Reads `/proc/<ppid>/exe` to determine the parent executable path
3. Falls back to `/proc/<ppid>/comm` if the exe symlink fails
4. Uses existing `parse_shell_from_path()` to identify the shell type
This maintains full backward compatibility - the fallback only activates
when environment variables are unavailable and an error would otherwise
occur.
## Test Plan
Tested locally with:
```bash
env -u ZSH_VERSION -u SHELL PATH="/usr/bin:/bin" $(which cargo) run -- tool update-shell --verbose
```

## Summary
This PR productionizes an idea I saw in
https://github.com/astral-sh/uv/issues/15248, which was added in Pixi:
https://github.com/prefix-dev/pixi/pull/4247. The core of the idea is
that if we install all build isolation-enabled packages first, and the
build isolation-disabled packages in a second phase, the sync is more
likely to "just work", because if all the build dependencies of the
build isolation-disabled packages are included as dependencies (as is
the case for `flash-attn`, at least), they'll be present.
This isn't really a silver bullet, because it requires that all the
build dependencies are included as first-party dependencies, and if you
have packages that want build isolation to be disabled but rely on other
packages that also require build isolation disabled, that won't work
either. I think `extra-build-dependencies` will be more robust and have
much better caching behavior, but this will get more cases right than
our current behavior, and I don't see any downsides.
Closes https://github.com/astral-sh/uv/issues/15301.
