2024-03-15 r/7695 feat(nix-compat/wire): add low-level wire format primitives codeFlorian Klink1-0/+1
This brings some initial Nix wire format parsing code, used in the nix daemon protocol, remote store/builder protocol, as well as the NAR format itself (note we already have more specialized code for the last one). Thanks to embr, this code already exists, in https://codeberg.org/gorgon/gorgon/src/branch/main/nix-daemon/src/wire.rs, and we can vendor it into here, as EUPL is compatible with GPL (in that direction). The code uses the tokio::io Reader and Writer traits, not the ones from the `futures` crate, as they provide some more convenient `read_u64_le` functions. More application-specific parsing code, as well as code to read strings, or bytes are left out for now, as we want to be be more restrictive w.r.t allowed max sizes, and need to parse bytes, not strings. The code slightly diverges, as we have clippy looped into CI. `Ok(…?)` can be turned into just the inner expression, and some .and_then can be expressed in a simpler fashion.

2023-10-16 r/6831 feat(nix-compat/{aterm,derivation}): init parserFlorian Klink1-0/+1
This provides a nom-based parser for Nix derivations in ATerm format, which can be reached via `Derivation::from_aterm_bytes`. Some of the lower-level ATerm primitives are moved into a (new) aterm module, and some more higher-level ones that construct derivation- specific types. Also, move the escape_bytes function into there, this is a generic ATerm thing.

2023-03-30 r/6060 refactor(tvix/nix-compat): move build_store_path out of derivationFlorian Klink1-18/+0
This doesn't have anything to do with ATerms, we just happen to be using the aterm representation of a Derivation as contents. Moving this into store_path/utils.rs makes these things much cleaner - Have a build_store_path_from_references function, and a build_store_path_from_fingerprint helper function that makes use of it. build_store_path_from_references is invoked from the derivation module which can be used to calculate the derivation path. In the derivation module, we also invoke build_store_path_from_fingerprint during the output path calculation.
