2023-09-05 r/6555 feat(tvix/store/pathinfosvc): provide listingFlorian Klink1-1/+3
This provides an additional method in the PathInfoService trait, as well as an RPC method on the gRPC layer to list all PathInfo objects in a PathInfoService.

2023-07-22 r/6439 feat(tvix/store/proto): use Bytes instead of Vec<u8>Florian Klink5-49/+57
Makes use of https://github.com/tokio-rs/prost/pull/341, which makes our bytes field cheaper to clone. It's a bit annoying to configure due to https://github.com/hyperium/tonic/issues/908, but the workaround does get the job done.

This will save us some copies, because a clone will simply create an additional pointer to the same data.

2023-07-21 r/6436 refactor(tvix/store): use bytes for node names and symlink targetsFlorian Klink5-65/+63
Some paths might use names that are not valid UTF-8. We should be able to represent them. We don't actually need to touch the PathInfo structures, as they need to represent StorePaths, which come with their own harder restrictions, which can't encode non-UTF8 data. While this doesn't change any of the wire format of the gRPC messages, it does however change the interface of tvix_eval::EvalIO - its read_dir() method does now return a list of Vec<u8>, rather than SmolStr. Maybe this should be OsString instead?

2023-07-21 r/6433 feat(tvix/nix-compat): have StorePath accept bytesFlorian Klink1-3/+4
The primary constructor for this is now from_bytes, from_string is simply calling .as_bytes() on the string, passing it along. The InvalidName error now contains a Vec<u8>, to encode the invalid name (which might not be a string anymore). from_absolute_path now accepts a &[u8] (even though we might want to make this a OSString of some sort). StorePath::validate_name has been degraded to a pub(crate) function. It's still used in src/derivation, even though it probably shouldn't at all - that cleanup is left for cl/8412 though.

This being a nested error makes things more complicated than necessary.

Once we support configuring services at runtime, we don't know what DirectoryService we're using at compile time. This also means, we can't explicitly use the is_closed method from GRPCPutter, without making it part of the DirectoryPutter itself.

Putting this in the PathInfoService trait makes much more sense, we can have direct control over where/how to cache the results in the implementation. This now requires each PathInfoService to hold pointers to BlobService and DirectoryService.

There's only one way to calculate NAR files, by walking through them. Things like caching such replies should be done closer to where we use these, composing NARCalculationService doesn't actually give us much. Instead, expose two functions, `nar::calculate_size_and_sha256` and `nar::writer_nar`, the latter writing NAR to a writer, the former using write_nar to only keeping the NAR size and digest.

2023-06-12 r/6269 feat(tvix/store): eliminate generics in BlobStoreFlorian Klink1-3/+1
To construct various stores at runtime, we need to eliminate associated types from the BlobService trait, and return Box<dyn …> instead of specific types. This also means we can't consume self in the close() method, so everything we write to is put in an Option<>, and during the first close we take from there.

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 Klink2-160/+26
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.

2023-04-09 r/6088 refactor(nix-compat): Properly encapsulate store path constructionJohn Ericson1-3/+3
Before there was code scattered about (e.g. text hashing module and derivation output computation) constructing store paths from low level building blocks --- there was some duplication and it was easy to make nonsense store paths. Now, we have roughly the same "safe-ish" ways of constructing them as C++ Nix, and only those are exposed: - Make text hashed content-addressed store paths - Make other content-addressed store paths - Make input-addressed fixed output hashes Change-Id: I122a3ee0802b4f45ae386306b95b698991be89c8 Reviewed-on: https://cl.tvl.fyi/c/depot/+/8411 Reviewed-by: flokli <flokli@flokli.de> Tested-by: BuildkiteCI
2023-03-30 r/6060 refactor(tvix/nix-compat): move build_store_path out of derivationFlorian Klink1-4/+4
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.
