We currently install NumPy to exercise native extensions in our system
Python tests, which requires an expensive source build on Pyston.
Replace it with a small checked-in C extension on CPython, PyPy, and
Pyston. We build and install the fixture, import it, and call its native
function. Build dependencies are pinned for the supported Python
versions, and the Rocky Linux and Amazon Linux jobs install the required
Python headers.
The Pyston validation step fell from [207 seconds on
main](https://github.com/astral-sh/uv/actions/runs/34968381082/job/104380124716)
to [7 seconds on the
PR](https://github.com/astral-sh/uv/actions/runs/34985252562/job/104438017363),
using the same pinned Pyston 2.3.5 image. Other interpreters were not
benchmarked.
Applies a patch to use Python 3.6 compatible types in our vendored
`packaging` implementation used in the interpreter query script. Adds
Python 3.6 and 3.7 test coverage in CI.
Fix#17524.
This adds a couple of new options to `scripts/check_system_python.py` to verify that it is running with the right interpreter version and that it would hopefully be the interpreter picked up by uv (although that isn't strictly necessary as other tests should fail in that case).
Additionally, since the path to the newly installed chocolatey python is not loaded from registry on every step, we now manually load it.
Beware, this will break `GITHUB_PATH` but this job wasn't using it at the moment.
## Summary
This adds GraalPy download metadata so that `uv python install graalpy`
works. See https://github.com/astral-sh/uv/issues/13114
## Test Plan
The existing integration test was changed to test this functionality.
## Summary
This PR adds system install tests to verify the behavior described in
#2798. It turns out this behavior _also_ affects Fedora and Amazon
Linux, we just didn't have the right conditions enabled (specifically,
you need to create the virtualenv with `python -m venv` to get these
symlinks), so the test suite was expanded to capture that.
The issue itself is also fixed by way of deduplicating the
`site-packages` entries.
Closes: https://github.com/astral-sh/uv/issues/2798
Installing and importing numpy tests for two cases:
* The python architecture and the package architecture don't match
(https://github.com/astral-sh/uv/issues/2326)
* The libc of python and that of the package don't match on linux
(musllinux vs manylinux, picking a compatible manylinux version)
All pylint deps are py3-none-any, so they don't catch those cases.
## Summary
This is essentially a wrapper around something like `--python $(which
python3)`, but gives users a portable and streamlined way to solve the
common pain point of using `uv` in GitHub Actions or a Docker container.
