2023-06-12 r/6278 refactor(tvix/store/blobsvc): drop Result<_,_> around open_writeFlorian Klink1-4/+1
We never returned Err here anyways, and we can still return an error during the first (or subsequent) write(s).

From 64 bytes to 100 KBytes. We need to provide a custom wrapper with a different Default instance. Change-Id: Id7c6c437b8183b355a9e388f98cef1622b363f64 Reviewed-on: https://cl.tvl.fyi/c/depot/+/8748 Tested-by: BuildkiteCI Reviewed-by: flokli <flokli@flokli.de>
2023-06-12 r/6273 refactor(tvix/store): use Arc instead of BoxFlorian Klink1-4/+4
This allows us to blob services without closing them before putting them in a box. We currently need to use Arc<_>, not Rc<_>, because the GRPC wrappers require Sync.

2023-06-12 r/6269 feat(tvix/store): eliminate generics in BlobStoreFlorian Klink1-10/+6
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.

2023-05-11 r/6133 refactor(tvix/store): remove ChunkServiceFlorian Klink1-158/+84
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.

2023-03-13 r/5959 refactor(tvix/store): use read_all_and_chunk in gRPC blobserviceFlorian Klink1-35/+38
This was the last piece of code using BlobWriter. We can also use `read_all_and_chunk`, it's just requires a bit more plumbing: - The data coming from the client (stream) needs to be mapped (we extract the .data field). - The stream needs to be turned into an (async) reader - The reader needs to be made sync, and that code using the sync reader needs to be in a `task::spawn_blocking`.

Use the FastCDC::cut function to ask fastcd for cutting points as we receive the data. Make sure to keep the last chunk in the temporary buffer, as we might not actually cut at the end. Also, use rayon to calculate the blake3 hash if the input data is > 128KiB.

2023-03-10 r/5925 feat(tvix/store): bump fastcdc, use v2020 versionFlorian Klink1-1/+1
This switches away from the less canonical "ronomon" version to the implementation as described in the [paper](https://ieeexplore.ieee.org/document/9055082) by Wen Xia, et al., in 2020. That version uses 64-bit hash values and tends to be faster than both the ronomon and v2016 versions, and produces the same chunking as the 2016 version. As per https://docs.rs/fastcdc/latest/fastcdc/#implementations-1, it's the recommended choice. The crate also gained support for streaming version of chunkers: https://docs.rs/fastcdc/latest/fastcdc/#large-data, which might be useful.

2023-03-10 r/5910 feat(tvix/store/blobservice): add GRPCBlobServiceWrapperFlorian Klink1-0/+231
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.
