## Summary
This seems to be one of the most consistent benchmark cases we have in
terms of standard deviation:
```
➜ hyperfine "target/profiling/main pip compile scripts/requirements/airflow.in" --runs 200
Benchmark 1: target/profiling/main pip compile scripts/requirements/airflow.in
Time (mean ± σ): 292.6 ms ± 6.6 ms [User: 414.1 ms, System: 194.2 ms]
Range (min … max): 282.7 ms … 320.1 ms 200 runs
```
For smaller benchmarks, scispacy and dtlssocket seem to be a bit more
consistent than our current jupyter benchmark, but it hasn't given us
any problems so I'll leave it for now.
Updates our Python interpreter discovery to conform to the rules
described in #2386, please see that issue for a full description of the
behavior. Briefly, we now will search for interpreters that satisfy a
requested version without stopping at the first Python executable.
Additionally, if retrieving information about an interpreter fails we
will continue to search for a working interpreter. We also add the
plumbing necessary to request Python implementations other than CPython,
though we do not add support for other implementations at this time.
A major internal goal of this work is to prepare for user-facing managed
toolchains i.e. fetching a requested version during `uv run`. These APIs
are not introduced, but there is some managed toolchain handling as
required for our test suite.
Some noteworthy implementation changes:
- The `uv_interpreter::find_python` module has been removed in favor of
a `uv_interpreter::discovery` module.
- There are new types to help structure interpreter requests and track
sources
- Executable discovery is implemented as a big lazy iterator and is a
central authority for source precedence
- `uv_interpreter::Error` variants were split into scoped types in each
module
- There's much more unit test coverage, but not for Windows yet
Remaining work:
- [x] Write new test cases
- [x] Determine correct behavior around executables in the current
directory
- _Future_: Combine `PythonVersion` and `VersionRequest`
- _Future_: Consider splitting `ManagedToolchain` into local and remote
variants
- _Future_: Add Windows unit test coverage
- _Future_: Explore behavior around implementation precedence (i.e.
CPython over PyPy)
Refactors split into:
- #3329
- #3330
- #3331
- #3332Closes#2386
Separates Windows tests from the rest because it's a pain and drops the
`python-patch` feature from testing so we can use the GitHub Actions
Python versions which bootstrap in 0 seconds instead of 2 minutes.
## 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.

A first step towards Python toolchain management in Rust.
First, we add a new crate to manage Python download metadata:
- Adds a new `uv-toolchain` crate
- Adds Rust structs for Python version download metadata
- Duplicates the script which downloads Python version metadata
- Adds a script to generate Rust code from the JSON metadata
- Adds a utility to download and extract the Python version
I explored some alternatives like a build script using things like
`serde` and `uneval` to automatically construct the code from our
structs but deemed it to heavy. Unlike Rye, I don't generate the Rust
directly from the web requests and have an intermediate JSON layer to
speed up iteration on the Rust types.
Next, we add add a `uv-dev` command `fetch-python` to download Python
versions per the bootstrapping script.
- Downloads a requested version or reads from `.python-versions`
- Extracts to `UV_BOOTSTRAP_DIR`
- Links executables for path extension
This command is not really intended to be user facing, but it's a good
PoC for the `uv-toolchain` API. Hash checking (via the sha256) isn't
implemented yet, we can do that in a follow-up.
Finally, we remove the `scripts/bootstrap` directory, update CI to use
the new command, and update the CONTRIBUTING docs.

Reproduced https://github.com/astral-sh/uv/issues/2941 and confirmed
fix.
We probably ought to have some ecosystem test coverage — this seems like
a good starting point we can extend to other projects in the future.
Following #2735 adds a system check that uses Homebrew. I think we were
never were actually using Homebrew's Python in the past, we were mislead
or something changed in the runners recently that broke it.
Add a single job for for fast lint tools. Rustfmt for rust, ruff for
python formatting and linting, prettier avoids inconsistent formatter
changes between pycharm and vscode.
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.
Giving this a try... just making all of these a normal part of CI.
This is probably slightly slower than our normal CI, but not by much (it
depends how bad of a roll we get on the Windows network performance).
Includes #2309 to reduce the overhead of adding more platforms.
Alternatively, we could gate these with a label and just run on main by
default (i.e. #2308)
First, replace all usages in files in-place. I used my editor for this.
If someone wants to add a one-liner that'd be fun.
Then, update directory and file names:
```
# Run twice for nested directories
find . -type d -print0 | xargs -0 rename s/puffin/uv/g
find . -type d -print0 | xargs -0 rename s/puffin/uv/g
# Update files
find . -type f -print0 | xargs -0 rename s/puffin/uv/g
```
Then add all the files again
```
# Add all the files again
git add crates
git add python/uv
# This one needs a force-add
git add -f crates/uv-trampoline
```
Run `cargo test` on windows in CI, pulling the switch on tier 1 windows
support.
These changes make the bootstrap script virtually required for running
the tests. This gives us consistency between and CI, but it also locks
our tests to python-build-standalone and an articificial `PATH`.
I've deleted the shell bootstrap script in favor of only the python one,
which also runs on windows. I've left the (sym)link creation of the
bootstrap in place, even though it is not used by the tests anymore.
I've reactivated the three tests that would previously stack overflow by
doubling their stack sizes. The stack overflows only happen in debug
mode, so this is neither a user facing problem nor an actual problem
with our code and this workaround seems better than optimizing our code
for case that the (release) compiler can optimize much better for.
The handling of patch versions will be fixed in a follow-up PR.

## Summary
Enables tests for macOS in CI, using the M1 runners (which are free in
public, but count against our quota in private
repos). For now, I'm just running them on `main` to save quota.
I did the math, and the M1 runners are the best value:
Closes#1053.
## Summary
We have some flags in Puffin that enable us to opt-in to certain tests.
To date, they've been opt-in, so we've run our tests with
`--all-features`. This PR makes them opt-out, and we now run tests with
default features.
The main motivation here is that I want to get tests working for macOS
on CI, but for unknown reasons, macOS can't compile the PyO3 features at
the same time as everything else due to strange linker issues. By
avoiding `--all-features` for tests, we thus avoid unnecessarily
including features that we don't actually use in Puffin.
I verified that the exact same number of tests (439) are run before and
after this change. For users, the primary difference is that you now
need to specify `--no-default-features --features pypi --features
python` to avoid (e.g.) including the Git tests.
A 1:1 port of the Bash script to Python for use on Windows.
Pulls some parts of #1068 but much more minimal. Avoids an additional
dependency on `requests`. Because we require `zstandard` to unzip the
distributions we unfortunately cannot be dependency free and cannot have
`bootstrap.sh` download the Python version needed to run this script
without it doing a non-trivial amount of work.
Retains the Bash script for now so you can bootstrap without Python
available. I may drop it in the future?
