Closes https://github.com/astral-sh/uv/issues/8213
I didn't mean to remove these when updating the regular expression.
Arguably, they shouldn't be used anymore, but we should make that choice
with intention.
As mentioned in https://github.com/astral-sh/uv/issues/8189
We only checked if an interpreter was free-threaded _when_ free-threaded
variants were requested. But we should not use free-threaded
interpreters unless explicitly requested.
## Summary
This PR declares and documents all environment variables that are used
in one way or another in `uv`, either internally, or externally, or
transitively under a common struct.
I think over time as uv has grown there's been many environment
variables introduced. Its harder to know which ones exists, which ones
are missing, what they're used for, or where are they used across the
code. The docs only documents a handful of them, for others you'd have
to dive into the code and inspect across crates to know which crates
they're used on or where they're relevant.
This PR is a starting attempt to unify them, make it easier to discover
which ones we have, and maybe unlock future posibilities in automating
generating documentation for them.
I think we can split out into multiple structs later to better organize,
but given the high influx of PR's and possibly new environment variables
introduced/re-used, it would be hard to try to organize them all now
into their proper namespaced struct while this is all happening given
merge conflicts and/or keeping up to date.
I don't think this has any impact on performance as they all should
still be inlined, although it may affect local build times on changes to
the environment vars as more crates would likely need a rebuild. Lastly,
some of them are declared but not used in the code, for example those in
`build.rs`. I left them declared because I still think it's useful to at
least have a reference.
Did I miss any? Are their initial docs cohesive?
Note, `uv-static` is a terrible name for a new crate, thoughts? Others
considered `uv-vars`, `uv-consts`.
## Test Plan
Existing tests
As per
https://matklad.github.io/2021/02/27/delete-cargo-integration-tests.html
Before that, there were 91 separate integration tests binary.
(As discussed on Discord — I've done the `uv` crate, there's still a few
more commits coming before this is mergeable, and I want to see how it
performs in CI and locally).
## Summary
Closes#7977. Makes `PythonDownloadRequest` account for the prerelease
part if allowed. Also stores the prerelease in `PythonInstallationKey`
directly as a `Prerelease` rather than a string.
## Test Plan
Correctly picks the relevant prerelease (rather than picking the most
recent one):

## Summary
This PR adds the ability to list available scripts in the environment
when `uv run` is invoked without any arguments.
It somewhat mimics the behavior of `rye run` command
(See https://rye.astral.sh/guide/commands/run).
This is an attempt to fix#4024.
## Test Plan
I added test cases. The CI pipeline should pass.
### Manuel Tests
```shell
❯ uv run
Provide a command or script to invoke with `uv run <command>` or `uv run script.py`.
The following scripts are available:
normalizer
python
python3
python3.12
See `uv run --help` for more information.
```

## Summary
PythonDownloadKey (cpython-3.13.0rc3-darwin-aarch64-none) and
PlatformTriple in `fetch-download-metadata.py` have a slight
inconsistency in the ordering of `os` and `arch`. In PythonDownloadKey,
`os` precedes `arch`, while in PlatformTriple, `arch` comes before
`platform` (equivalent to os). This difference in ordering affects the
sorting logic, giving arch higher priority than platform in the
`download-metadata.json` file, leading to a little bit of unexpected
order of entries.

This PR adds support for upgrading the build environment of tools with
the addition of a ```--python``` argument to ```uv upgrade```, as
specified in #7471.
Some things to note:
- I added support for individual packages — I didn't think there was a
good reason for ```--python``` to only apply to all packages
- Upgrading with ```--python``` also upgrades the package itself — I
think this is fair as if a user wants to _strictly_ switch the version
of Python being used to build a tool's environment they can use ```uv
install```. This behavior can of course be modified if others don't
agree!
Closes https://github.com/astral-sh/uv/issues/6297.
Closes https://github.com/astral-sh/uv/issues/7471.
Closes#7118
This only really affects managed interpreters, as we exclude alternative
Python implementations from the search path during the
`VersionRequest::executable_names` part of discovery.

There are two parts to this.
The first is a restructuring and refactoring. We had some debt around
expected executable name generation, which we address here by
consolidating into a single function that generates a combination of
names. This includes a bit of extra code around free-threaded variants
because this was written on top of #7431 — I'll rebase that on top of
this.
The second addresses some bugs around alternative implementations.
Notably, `uv python list` does not discovery executables with
alternative implementation names. Now, we properly generate all of the
executable names for `VersionRequest::Any` (originally implemented in
https://github.com/astral-sh/uv/pull/7508) to properly show all the
implementations we can find:
```
❯ cargo run -q -- python list --no-python-downloads
cpython-3.12.6-macos-aarch64-none /opt/homebrew/opt/python@3.12/bin/python3.12 -> ../Frameworks/Python.framework/Versions/3.12/bin/python3.12
cpython-3.11.10-macos-aarch64-none /opt/homebrew/opt/python@3.11/bin/python3.11 -> ../Frameworks/Python.framework/Versions/3.11/bin/python3.11
cpython-3.9.6-macos-aarch64-none /Library/Developer/CommandLineTools/usr/bin/python3 -> ../../Library/Frameworks/Python3.framework/Versions/3.9/bin/python3
pypy-3.10.14-macos-aarch64-none /opt/homebrew/bin/pypy3 -> ../Cellar/pypy3.10/7.3.17/bin/pypy3
```
While doing both of these changes, I ended up changing the priority of
interpreter discovery slightly. For example, given that the executables
are in the same directory, do we query `python` or `python3.10` first
when you request `--python 3.10`? Previously, we'd check `python3.10`
but I think that was an incorrect optimization. I think we should always
prefer the bare name (i.e. `python`) first. Similarly, this applies to
`python` and an executable for an alternative implementation like
`pypy`. If it's not compatible with the request, we'll skip it anyway.
We might have to query more interpreters with this approach but it seems
rare.
Closes https://github.com/astral-sh/uv/issues/7286 superseding
https://github.com/astral-sh/uv/pull/7508
As we support more complex Python discovery behaviors such as:
- #7431
- #7335
- #7300
`Any` is no longer accurate, we actually are looking for a reasonable
default Python version to use which may exclude the first one we find.
Separately, we need the idea of `Any` to improve behavior when listing
versions (e.g., #7286) where we do actually want to match _any_ Python
version. As a first step, we'll rename `Any` to `Default`. Then, we'll
introduce a new `Any` that actually behaves as we'd expect.
## Summary
This PR adds support to include Python pre-releases when requesting
versions.
Check out the docs for commands that support the `Python` option:
```text
--python, -p python
The Python interpreter to use for the virtual environment.
```
At least the following scenarios are supported:
```bash
3.13.0a1
3.13b2
3.13rc4
313rc1
```
## Test Plan
I added a basic unit test to `uv/crates/uv-python/src/discovery.rs`. I
could have added more, but I have not discovered any relevant places.
CI passes
Note: I was unable to execute the entire test set locally. There were at
least some timeout issues (some tests took over 60 seconds).

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`.
Following #7263 the 3.13.0rc2 releases are at the top of the download
list but we should not select them unless 3.13 is actually requested.
Prior to this, `uv python install` would install `3.13.0rc2`.
