2023-05-23 r/6177 refactor(tvix/store/directorysvc): move from Vec<u8> to B3DigestFlorian Klink1-2/+9
This introduces a new struct, B3Digest, which internally holds a Vec<u8>, but only allows construction with 32 bytes. It also implements display, which will print the base64 representation. This should reduce some boilerplate when parsing Vec<u8>.

2023-05-11 r/6133 refactor(tvix/store): remove ChunkServiceFlorian Klink1-0/+2
Whether chunking is involved or not, is an implementation detail of each Blobstore. Consumers of a whole blob shouldn't need to worry about that. It currently is not visible in the gRPC interface either. It shouldn't bleed into everything. Let the BlobService trait provide `open_read` and `open_write` methods, which return handles providing io::Read or io::Write, and leave the details up to the implementation. This means, our custom BlobReader module can go away, and all the chunking bits in there, too. In the future, we might still want to add more chunking-aware syncing, but as a syncing strategy some stores can expose, not as a fundamental protocol component. This currently needs "SyncReadIntoAsyncRead", taken and vendored in from https://github.com/tokio-rs/tokio/pull/5669. It provides a AsyncRead for a sync Read, which is necessary to connect our (sync) BlobReader interface to a GRPC server implementation. As an alternative, we could also make the BlobReader itself async, and let consumers of the trait (EvalIO) deal with the async-ness, but this is less of a change for now. In terms of vendoring, I initially tried to move our tokio crate to these commits, but ended up in version incompatibilities, so let's vendor it in for now.

2023-03-30 r/6060 refactor(tvix/nix-compat): move build_store_path out of derivationFlorian Klink1-3/+3
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.

2023-03-10 r/5910 feat(tvix/store/blobservice): add GRPCBlobServiceWrapperFlorian Klink1-0/+3
This takes a BlobService and ChunkService in the constructor, and provides a [proto::blob_service_server::BlobService] trait for it. Implementing proto::blob_service_server::BlobService is a lot of surface to cover, and providing this wrapper will make individual implementations taking care of how to store chunks or chunking information much simpler.
