## Summary We only need to store one hash -- it should be the "strongest" hash. In practice, most registries (like PyPI) only serve one, and we only compute a SHA256 hash for direct URLs. Part of: https://github.com/astral-sh/uv/issues/4924 ## Test Plan I verified that changing: ```diff diff --git a/crates/distribution-types/src/hash.rs b/crates/distribution-types/src/hash.rs index 553a74f55..d36c62286 100644 --- a/crates/distribution-types/src/hash.rs +++ b/crates/distribution-types/src/hash.rs @@ -31,7 +31,7 @@ impl<'a> HashPolicy<'a> { pub fn algorithms(&self) -> Vec<HashAlgorithm> { match self { Self::None => vec![], - Self::Generate => vec![HashAlgorithm::Sha256], + Self::Generate => vec![HashAlgorithm::Sha256, HashAlgorithm::Sha512], Self::Validate(hashes) => { let mut algorithms = hashes.iter().map(HashDigest::algorithm).collect::<Vec<_>>(); algorithms.sort(); ``` Then running `uv lock` with a URL gave me: ```toml [[distribution]] name = "iniconfig" version = "2.0.0" source = { url = "62565a6e1c/iniconfig-2.0.0-py3-none-any.whl" } wheels = [ { url = "62565a6e1c/iniconfig-2.0.0-py3-none-any.whl", hash = "sha512:44cc53a6c8dd7cf4d6d52bded308bcc4b4f85fff2ed081f60f7d4beaa86a7cde6d099e3976331232d4cbd472ad5d1781064725b0999c7cd3a2a4d42df687ee81" }, ] ```
