Currently, our trampoline is used to convert `<command> [args]` to
`python <command> [args]` for script entrypoints installed into virtual
environments. For #8458, it'd be nice to convert a shim `python3.12
[args]` to `python [args]`. Here, we modify the trampolines to support
this use-case.
The only change we really need here is to avoid injecting `<command>`
into the child process. We change the "magic number" at the end of the
trampoline executables from `UVUV` to `UVSC` and `UVPY` which define
"script" and "python" variants to the trampoline. We then omit the
`<command>` injection in the latter case. We also omit writing the zip
script payload.
To support construction of the new variant, a new
`uv-trampoline-builder` crate is introduced — this avoids requirements
on `uv-install-wheel` in future work. I also use `uv-trampoline-builder`
to consolidate some of the test setup for `uv-trampoline`.
There should be no backwards compatibility concerns, since trampolines
are fully self-referential.
I rebased to fix the commits at the end, as this took many iterations to
get working via CI. This should roughly be reviewable by commit if you
prefer.
It seems unintentional that we basically did nothing on these
alternative platforms? It seems like an artifact from some previous
change.
I'm not sure it's worth running Clippy multiple times. We could also
just reduce the matrix here.
Cherry-picked from #8347
Might fix https://github.com/astral-sh/uv/issues/6940 — I'm not seeing a
failure over there after this change. I think there may be some problem
with concurrent reads of junctioned files on the DevDrive? It's really
hard to say.
We might lose some important test coverage with this change. I'm not
sure what to do about that either.
Closes https://github.com/astral-sh/uv/issues/8228
e.g., on this branch
```
❯ uv python install 3.13t 3.13
❯ cargo build
❯ cargo run -q --bin uvx -- --from build python -c "import sys; print(sys.base_prefix)"
/Users/zb/.local/share/uv/python/cpython-3.13.0-macos-aarch64-none
❯ cargo run -q --bin uvx -- -p 3.13 --from build python -c "import sys; print(sys.base_prefix)"
/Users/zb/.local/share/uv/python/cpython-3.13.0-macos-aarch64-none
❯ cargo run -q --bin uvx -- -p 3.13t --from build python -c "import sys; print(sys.base_prefix)"
/Users/zb/.local/share/uv/python/cpython-3.13.0+freethreaded-macos-aarch64-none
```
and on main
```
❯ cargo build
❯ cargo run -q --bin uvx -- --from build python -c "import sys; print(sys.base_prefix)"
Installed 3 packages in 12ms
/Users/zb/.local/share/uv/python/cpython-3.13.0+freethreaded-macos-aarch64-none
```
I want to add more test coverage around this, but I've noticed the
free-threaded discovery tests are a bit off as-is and it'll be a bigger
task. I think the recent bugs around discovery indicate we should invest
more into that test framework.
## Summary
Reverts #8181 and #8182.
The fix is in b849f0f, which extends the run timeout to allow xwin to
download the Windows SDK files, which can take 10+ minutes.
Closes https://github.com/rust-cross/cargo-xwin/issues/127
## Test Plan
Existing CI should pass.
## Notes
xwin jobs will take a long time the first time due to cache re-warming.
## Summary
Update CI config to test against GraalPy 24.1, which makes a workaround
in the CI config unnecessary.
## Test Plan
The updated CI config is tested.

## Summary
I started learning `uv` by inspecting the source code.
I've noticed that your shell scripts are very good! Which is rare!
## Test Plan
I propose to add `shellcheck` to the CI.
It is a great tool to help finding bugs and style issues in shell code.
Techincal details:
- This CI job will only run when any `.sh` files are changed (or the job
definition file)
- It takes just several seconds even on local machine:
```
» time shellcheck -S style **/*.sh
shellcheck -S style **/*.sh 0.02s user 0.05s system 61% cpu 0.123 total
```
- It is easy to use, for example: I just fixed the single problem you
had in your code with `# shellcheck disable=SC1091`
- I am using this tool for around 8 years now and didn't have any
issues. Examples:
https://github.com/sobolevn/git-secret/blob/ca899f3b694187f9027161f537414422ee99c483/.github/workflows/test.yml#L22-L27
and
https://github.com/wemake-services/wemake-django-template/blob/master/.github/workflows/shellcheck.yml
But, I understand that build / lint tools are very subjective. So, feel
free to close :)
## Summary
Closes https://github.com/astral-sh/uv/issues/6972
This is not breaking since `MACOSX_DEPLOYMENT_TARGET` will stay the same
(currently defaulting to 10.12) so a
`uv-x.y.z-py3-none-macosx_10_12_x86_64.whl` will still be built

## Summary
closes#4828
First iteration for an implementation. I need to add more tests but
wanted your opinion on the implementation first.
<!-- What's the purpose of the change? What does it do, and why? -->
## Test Plan
Currently tested using the following command but will add tests shortly:
```console
D:\repo\uv> cargo run venv -p 3.13t && .venv\Scripts\python.exe
Finished `dev` profile [unoptimized + debuginfo] target(s) in 0.52s

## Summary
Because a problem was found with Powershell and combining the generated
completion scripts for uv and uvx, let's try separating uv and uvx
command completion scripts.
The generated powershell script template can be seen in clap_complete
source, and it starts with `using` directives, which makes it impossible
(apparently) to concatenate two of those script outputs.
As a side effect, this is available under `uv tool run
--generate-shell-completion` too.
Fixes#7482
## Test Plan
- `eval "$(cargo run --bin uvx -- --generate-shell-completion bash)"`
- Test Powershell
Similar to our semantics for packages with pre-release versions.
We will not use prerelease versions unless there are only prerelease
versions available, a specific version is requested,
or the prerelease version is found in a reasonable source (active
environment, explicit path, etc. but not `PATH`).
For example, `uv python install 3.13 && uv run python --version` will no
longer use `3.13.0rc2` unless that is the only Python version available,
`--python 3.13` is used, or that's the Python version that is present in
`.venv`.
## Summary
Noticed that running `cargo dev generate-all` on `main` produced changes
and saw that that the command is not run on the CI nor as a pre-commit
hook.
Not sure if having the command running as a pre-commit hook is something
we want, so I can remove it if you prefer. I find that nice to have as
it's probably easy to forget to run it, especially for new contributors
(and it will only run if there are changes in `uv_cli` or `uv_settings`
crates).
## Test Plan
- Added `cargo dev generate-all --mode check` on the CI, which produced
[this failing
job](https://github.com/astral-sh/uv/actions/runs/10648055597/job/29516699393)
- Ran `cargo dev generate-all` locally and committed the changes, which
produced [this succeeding
job](https://github.com/astral-sh/uv/actions/runs/10648076910/job/29516744942)
As suggested by @samypr100 on #6680:
https://github.com/astral-sh/uv/pull/6680#issuecomment-2313607984
## Summary
Instead of using `UV_INTERNAL__TEST_DIR`, it simply exports `TEMP` when
running Windows jobs.
## Test Plan
I'm going to run this manually under ProcMon on my Windows machine and
see where uv writes temp files, hopefully to the dev drive and not
`%(LOCAL)APPDATA%` or something.
I'm going to commit a dummy code change and look at build time changes
in CI.
## Summary
This PR makes `cargo test | windows` faster in CI.
### Before

### After

## Also
This PR disables the `brotli` feature of `async-compression` since it's
not strictly needed, but this has little to do with the improvements
(it's still less code to build).
This PR introduces additional code in uv tool uninstall to ignore errors
(that only seem to happen on ReFS, ie. on Dev Drives) akin to "the thing
we're trying to delete cannot be deleted because it's already being
deleted".
If `raw_os_error` was stable we could do u32 matching instead of that
`.to_string().contains()` abomination.
