2023-09-22 r/6629 refactor(tvix): move castore into tvix-castore crateFlorian Klink1-196/+0
This splits the pure content-addressed layers from tvix-store into a `castore` crate, and only leaves PathInfo related things, as well as the CLI entrypoint in the tvix-store crate. Notable changes: - `fixtures` and `utils` had to be moved out of the `test` cfg, so they can be imported from tvix-store. - Some ad-hoc fixtures in the test were moved to proper fixtures in the same step. - The protos are now created by a (more static) recipe in the protos/ directory. The (now two) golang targets are commented out, as it's not possible to update them properly in the same CL. This will be done by a followup CL once this is merged (and whitby deployed) Bug: https://b.tvl.fyi/issues/301 Change-Id: I8d675d4bf1fb697eb7d479747c1b1e3635718107 Reviewed-on: https://cl.tvl.fyi/c/depot/+/9370 Reviewed-by: tazjin <tazjin@tvl.su> Reviewed-by: flokli <flokli@flokli.de> Autosubmit: flokli <flokli@flokli.de> Tested-by: BuildkiteCI Reviewed-by: Connor Brewster <cbrewster@hey.com>
2023-09-18 r/6606 refactor(tvix/store/blobsvc): make BlobStore asyncFlorian Klink1-13/+32
We previously kept the trait of a BlobService sync. This however had some annoying consequences: - It became more and more complicated to track when we're in a context with an async runtime in the context or not, producing bugs like https://b.tvl.fyi/issues/304 - The sync trait shielded away async clients from async worloads, requiring manual block_on code inside the gRPC client code, and spawn_blocking calls in consumers of the trait, even if they were async (like the gRPC server) - We had to write our own custom glue code (SyncReadIntoAsyncRead) to convert a sync io::Read into a tokio::io::AsyncRead, which already existed in tokio internally, but upstream ia hesitant to expose. This now makes the BlobService trait async (via the async_trait macro, like we already do in various gRPC parts), and replaces the sync readers and writers with their async counterparts. Tests interacting with a BlobService now need to have an async runtime available, the easiest way for this is to mark the test functions with the tokio::test macro, allowing us to directly .await in the test function. In places where we don't have an async runtime available from context (like tvix-cli), we can pass one down explicitly. Now that we don't provide a sync interface anymore, the (sync) FUSE library now holds a pointer to a tokio runtime handle, and needs to at least have 2 threads available when talking to a blob service (which is why some of the tests now use the multi_thread flavor). The FUSE tests got a bit more verbose, as we couldn't use the setup_and_mount function accepting a callback anymore. We can hopefully move some of the test fixture setup to rstest in the future to make this less repetitive.

2023-07-21 r/6437 feat(tvix/store/digests): use bytes::Bytes instead of Vec<u8>Florian Klink1-1/+1
This will save us some copies, because a clone will simply create an additional pointer to the same data.

2023-07-21 r/6434 feat(tvix/store/blobservice): implement seekFlorian Klink1-2/+2
For memory and sled, it's trivial, as we already have a Cursor<Vec<u8>>. For gRPC, we simply reject going backwards, and skip n bytes for now. Once the gRPC protocol gets support for offsets and verified streaming, this can be improved.

2023-06-30 r/6367 fix(tvix/store/blobservice): write into hasher from b, not bufFlorian Klink1-1/+1
buf contains everything written so far, whereas b is the slice passed in the current write() call. If we copy from &buf, we end up with the wrong hash, because we keep writing the wrong data to the hash function.

2023-06-14 r/6302 feat(tvix/store/blobsvc): add from_addrFlorian Klink1-0/+62
This allows constructing blob stores with a URL syntax at runtime, by passing the --blob-service-addr arg. We probably still want to have some builder pattern here, to allow additional schemes to be registered.

2023-06-12 r/6269 feat(tvix/store): eliminate generics in BlobStoreFlorian Klink1-25/+64
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 Klink1-29/+58
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.
