## 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
```
Benchmark 1: ./target/profiling/uv (resolve-warm)
Time (mean ± σ): 14.9 ms ± 0.3 ms [User: 3.0 ms, System: 17.3 ms]
Range (min … max): 14.1 ms … 15.8 ms 169 runs
Benchmark 2: ./target/profiling/baseline (resolve-warm)
Time (mean ± σ): 16.1 ms ± 0.3 ms [User: 3.9 ms, System: 18.7 ms]
Range (min … max): 15.1 ms … 17.3 ms 162 runs
Summary
./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.
## Summary
See: https://github.com/axodotdev/cargo-dist/releases/tag/v0.17.0.
Relevant:
> The only reason you might want to override this setting is if you're
using [dispatch-releases =
true](https://opensource.axo.dev/cargo-dist/book/reference/config.html#dispatch-releases)
and you really want your git tag to be the last operation in your
release process (because creating a GitHub Release necessarily creates
the git tag if it doesn't yet exist, and many organizations really don't
like when you delete/change git tags). In this case setting
github-release = "announce" will accomplish that, but the above race
conditions would then apply.
We _do_ use `dispatch-releases = true`, and we _do_ want the git tag to
be the last operation, so we need to set `github-release = "announce"`
to preserve our current behavior.
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.
This PR re-adds the `aarch64-unknown-linux-gnu` binary, which will also
add the `manylinux_2_28` wheel for `aarch64` (in addition to the now
dual-tagged `musllinux_1_1` and `manylinux_2_217` wheel for `aarch64`).
We can consider dropping that _wheel_, but in my assessment removing a
release asset should now be treated as a breaking change -- so removing
it in a patch release was incorrect.
Closes https://github.com/astral-sh/uv/issues/4122.
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:

- #3330
- #3331

## Summary
Restore API-compatibility with pre-1.1.0 versions of the `zip` crate,
and pin the dependency to the 0.6 series, due to concerns discussed in
https://github.com/astral-sh/uv/issues/3642.
## Test Plan
```
cargo run -p uv-dev -- fetch-python
cargo test
```

## Summary
Fix#3439 by retagging the statically linked musl binary for
manylinux2014. This is the most conservative option;
the regular manylinux one could be removed as well, and I expect other
archs could probably do this as well.
<!-- What's the purpose of the change? What does it do, and why? -->
## Test Plan
Testing on manylinux.

This is needed to include uv in manylinux, which has both the
musllinux_1_1 and musllinux_1_2 images.
## Summary
We are looking into including uv in the `pypa/manylinux` docker images,
so that cibuildwheel will be able to use it. But to do so, we need all
actively supported images to be able to take it, including
musllinux_1_1.
## Test Plan
The test was updated to make sure Alpine 3.12, which musllinux was based
on, can run uv.
The binary build does need to be triggered on this PR to make sure it
works. Ah,
5b6040184d/.github/workflows/build-binaries.yml (L15-L20)
is a good idea, nice.
Will need a followup to fill out the other platforms `pypa/manylinux`
supports for musllinux.
