See https://github.com/astral-sh/uv/issues/2617 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. <img width="1023" alt="Screenshot 2024-04-08 at 17 12 15" src="https://github.com/astral-sh/uv/assets/2586601/57bd3cf1-7477-4bb8-a8e9-802a00d772cb"> |
