2024-01-12 r/7370 refactor(tvix/store/nar/renderer): don't require Arc, Clone or SyncFlorian Klink1-28/+45
To render NARs, we're fine with a simple AsRef to a BlobService and DirectoryService. We just need to have the function pass back the references, so we can reuse it after the recursion.

We need to be a bit careful and pass the BlobService around (similar to how we already do with the directory_putter), but that allows getting rid of a bunch of annoying trait bounds. We also stop spawning additional tasks where we can just use block_on.

Allow taking advantage of the buffer of the underlying reader to avoid unnecessary copies of file data. We can't easily implement the methods of BufRead directly, since we have some extra I/O to perform in the final consume() invocation. That could be resolved at the cost of additional bookkeeping, but this will suffice for now.

This adds a function that can ingest a NAR file into a given blob_service and directory_service, returning the root node. Passing around the directory_putter is a bit annoying, but at least for this linear "reading through a NAR" case, we don't need it to be clone or sync.

2023-09-22 r/6629 refactor(tvix): move castore into tvix-castore crateFlorian Klink2-20/+20
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>
2023-09-21 r/6623 refactor(tvix/store): Asyncify PathInfoService and DirectoryServiceConnor Brewster1-23/+38
We've decided to asyncify all of the services to reduce some of the pains going back and for between sync<->async. The end goal will be for all the tvix-store internals to be async and then expose a sync interface for things like tvix eval io.

2023-09-18 r/6606 refactor(tvix/store/blobsvc): make BlobStore asyncFlorian Klink1-7/+8
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.

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?

2023-05-11 r/6133 refactor(tvix/store): remove ChunkServiceFlorian Klink2-63/+28
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.
