Add an experimental JSON format for METADATA and WHEEL files in the uv build backend to have a reference what it would look like and to demonstrate that the actual change is just a few lines, how much easier it is than the existing email-ish format.
## 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
Add torch cuda 12.9 backend

## 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.

## Summary
<!-- What's the purpose of the change? What does it do, and why? -->
Currently record hashes are the hex encoded sha-256 sum. However,
they're supposed to be urlsafe-base64-nopad.
https://packaging.python.org/en/latest/specifications/recording-installed-packages/#the-record-fileFixes#15398
## Test Plan
<!-- How was it tested? -->
Build any wheel
```
uv build --wheel
```
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.
## Summary
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.
Closes https://github.com/astral-sh/uv/issues/15386.

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
```
```text

## 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.

## Summary
Fix WindowsRunnable::from_script_path to correctly append extensions
instead of replacing them when resolving executable paths. This resolves
https://github.com/astral-sh/uv/issues/15165#issue-3304086689.
- Add add_extension_to_path helper that appends extensions properly
- Update extension resolution to use the new helper
- Add tests
## Test Plan
Added unit tests for the new and existing functionality that the change
touches. Tested manually locally on Windows.

Correct typo. "uv cache clear" is not a command.

## Summary
With this PR, we track the settings that were used to build a wheel
(`--config-settings`, plus any `extra-build-dependencies` or
`extra-build-variables`) and write those to the `.dist-info` directory
upon install. This then allows us to "reject" already-installed wheels,
if the user changes the build dependencies or `--config-settings` (or,
crucially, if they use `match-runtime = true` and the resolution
changes).
Closes https://github.com/astral-sh/uv/issues/15218.
