## Summary
This PR adds a new job to test that PyPy venvs are correctly created on
Windows and they contain all the expected binaries.
## Test Plan
Just let CI run.
## Summary
Should fix#2092.
This PR changes `uv venv` so it also creates symlinks to `pypy` on Unix
and copies executables on Windows when creating a new environment using
PyPy.
I found a bit of discrepancy between creation of a venv using `python`
and `uv`, as using `python` brings all the executables with it. While
`uv` brings only those without any version number, at least on Windows.
The behaviour is different on Unix as we take the versioned symlinks
too.
Some examples below.
`python -m venv` generates the following `Scripts` folder.
```

## Test Plan
To verify the correct behaviour:
1. Download and install PyPy from [official
website](https://www.pypy.org/download.html)
2. Call `uv venv -p <path_to_pypy_>`
3. Run `.\.venv\Scripts\activate` on Windows or
`./.venv/Scripts/activate` on Unix
4. Run `pypy`
I thought of writing some automated tests but I couldn't rely on `uv
python install` command to install PyPy as it's not in the list of
installable Python builds.
## Summary
Move completely off tokio's multi-threaded runtime. We've slowly been
making changes to be smarter about scheduling in various places instead
of depending on tokio's general purpose work-stealing, notably
https://github.com/astral-sh/uv/pull/3627 and
https://github.com/astral-sh/uv/pull/4004. We now no longer benefit from
the multi-threaded runtime, as we run on all I/O on the main thread.
There's one remaining instance of `block_in_place` that can be swapped
for `rayon::spawn`.
This change is a small performance improvement due to removing some
unnecessary overhead of the multi-threaded runtime (e.g. spawning
threads), but nothing major. It also removes some noise from profiles.
## Test Plan

./target/profiling/uv (resolve-warm) ran
1.08 ± 0.03 times faster than ./target/profiling/baseline (resolve-warm)
```
## Summary
Partially closes#1917
This PR picks up on some of the great work from #1864 and opted to keep
`panic_immediate_abort` (for size reasons). I split the PR in different
isolated commits in case we want to separate/cherry-pick them out.
1. The first commit ports mostly all std changes from that PR into this
PR. Binary sizes stayed the same ~16kb.
2. The second commit migrates our existing usage of windows-sys to
windows for a safer ffi calls with Results!. It also changes all large
unsafe blocks to be isolated to the actual unsafe calls, and switches
some areas to use std such as getenv port ( which seemed buggy! ) from
launcher.c. In addition, this also adds more error checking in order to
match some missing assertions from distlib's launcher.c. Note, due to
the additional .text data, the binary sizes increased to ~20.5kb, but we
can cut back on some of the added error msgs as needed.
3. The third commit switches to using xwin for building on all 3
supported trampoline targets for sanity, and adds a CI bloat check for
core::fmt and panic as a precaution. Sadly, this will invalidate the
xwin cache on the first run.
## Test Plan
Most changes were tested on a couple of local GUI apps and console apps,
also tested some of the error states manually by using SetLastError at
different points in the code and/or passing in invalid handles.
I'm not sure how far we can get with migrating some of the other calls
without increasing binary size substantially. An initial attempt at
using std::path didn't seem so bad size wise when I tried it (~1k). On
other cases, such as std::process::exit added ~10k to the total binary
size.

Whew this is a lot.
The user-facing changes are:
- `uv toolchain` to `uv python` e.g. `uv python find`, `uv python
install`, ...
- `UV_TOOLCHAIN_DIR` to` UV_PYTHON_INSTALL_DIR`
- `<UV_STATE_DIR>/toolchains` to `<UV_STATE_DIR>/python` (with
[automatic
migration](https://github.com/astral-sh/uv/pull/4735/files#r1663029330))
- User-facing messages no longer refer to toolchains, instead using
"Python", "Python versions" or "Python installations"
The internal changes are:
- `uv-toolchain` crate to `uv-python`
- `Toolchain` no longer referenced in type names
- Dropped unused `SystemPython` type (previously replaced)
- Clarified the type names for "managed Python installations"
- (more little things)
## Summary
Updates default toolchain to
[1.79](https://blog.rust-lang.org/2024/06/13/Rust-1.79.0.html).
There didn't seem to be any breaking changes besides xwin now requiring
lld llvm linker.
## Test Plan
Existing tests.
e.g. failure at
2681531811
Seems to be some sort of issue where they're updating their package
repository / database causing a spurious failure. I've seen this fail a
lot lately.
So we can skip them when there are not code changes and still enforce
our required checks (xref #4438)
Otherwise, the names are dynamic and they are forever expected (see
#4426 for example)
It was becoming problematic that the virtual environment test context
diverged from the other one i.e. we had to implement filtering twice.
This combines the contexts and tweaks the `TestContext` API and
filtering mechanisms for Python versions. Combined with my previous
changes to the test context at #4364 and
https://github.com/astral-sh/uv/pull/4368 this finally unblocks the
snapshots for test cases in #4360 and
https://github.com/astral-sh/uv/pull/4362.
Extends #3726
Moves toolchain storage out of `UV_BOOTSTRAP_DIR` (`./bin`) into the
proper user data directory as defined by #3726.
Replaces `UV_BOOTSTRAP_DIR` with `UV_TOOLCHAIN_DIR` for customization.
Installed toolchains will be discovered without opt-in, but the idea is
still that these are not yet user-facing.
## 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.
Closes: https://github.com/astral-sh/uv/issues/2798

Note this also includes:
- #2918
- #2931 (pending)
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.
