Extends https://github.com/astral-sh/uv/pull/4121 Part of #2607 Adds support for managed toolchain fetching to `uv venv`, e.g. ``` ❯ cargo run -q -- venv --python 3.9.18 --preview -v DEBUG Searching for Python 3.9.18 in search path or managed toolchains DEBUG Searching for managed toolchains at `/Users/zb/Library/Application Support/uv/toolchains` DEBUG Found CPython 3.12.3 at `/opt/homebrew/bin/python3` (search path) DEBUG Found CPython 3.9.6 at `/usr/bin/python3` (search path) DEBUG Found CPython 3.12.3 at `/opt/homebrew/bin/python3` (search path) DEBUG Requested Python not found, checking for available download... DEBUG Using registry request timeout of 30s INFO Fetching requested toolchain... DEBUG Downloading https://github.com/indygreg/python-build-standalone/releases/download/20240224/cpython-3.9.18%2B20240224-aarch64-apple-darwin-pgo%2Blto-full.tar.zst to temporary location /Users/zb/Library/Application Support/uv/toolchains/.tmpgohKwp DEBUG Extracting cpython-3.9.18%2B20240224-aarch64-apple-darwin-pgo%2Blto-full.tar.zst DEBUG Moving /Users/zb/Library/Application Support/uv/toolchains/.tmpgohKwp/python to /Users/zb/Library/Application Support/uv/toolchains/cpython-3.9.18-macos-aarch64-none Using Python 3.9.18 interpreter at: /Users/zb/Library/Application Support/uv/toolchains/cpython-3.9.18-macos-aarch64-none/install/bin/python3 Creating virtualenv at: .venv INFO Removing existing directory Activate with: source .venv/bin/activate ``` The preview flag is required. The fetch is performed if we can't find an interpreter that satisfies the request. Once fetched, the toolchain will be available for later invocations that include the `--preview` flag. There will be follow-ups to improve toolchain management in general, there is still outstanding work from the initial implementation.
