2023-09-20 r/6622 refactor(tvix/store/fs): Separate FUSE and filesystem codeConnor Brewster9-131/+138
In prepration for adding virtiofs support, I thought it would make sense to split out the filesystem implementation from FUSE itself. The `fs` module holds the tvix-store filesystem implemetation and the `fuse` module holds the code to spawn a FUSE daemon backed by multiple threads.

2023-09-20 r/6621 refactor(tvix/store/fuse): Switch from fuser to fuse-backend-rsConnor Brewster7-345/+496
This switches the FUSE implementation from fuser to fuse-backend-rs. fuse-backend-rs is designed to work with both FUSE and virtiofs. Virtiofs support will make it possible to plug the tvix-store into a microvm and have `/nix/store` access without having to setup FUSE inside the guest. Additionally fuse-backend-rs has nice support for running multiple FUSE threads and has some async support. The goal of this commit is to mechanically switch over to fuse-backend-rs with minimal changes. I did have to add some locks here and there because fuse-backend-rs uses `&self` on all methods whereas fuser uses `&mut self`. `&self` is required for concurrent access to the FUSE server, so this makes sense. We can consider switching to concurrent maps and use some other techniques to reduce lock contention and critical section size.

2023-09-18 r/6606 refactor(tvix/store/blobsvc): make BlobStore asyncFlorian Klink20-881/+1249
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.

2023-09-04 r/6550 refactor(tvix/{cli,store}): move TvixStoreIO to tvix-cli crateFlorian Klink4-367/+55
This trait is eval-specific, there's no point in dealing with these things in tvix-store. This implements the EvalIO interface for a Tvix store. The proper place for this glue code (for now) is tvix-cli, which knows about both tvix-store and tvix-eval. There's one annoyance with this move: The `tvix-store import` subcommand previously also used the TvixStoreIO implementation (because it conveniently did what we wanted). Some of this code had to be duplicated, mostly logic to calculate the NAR-based output path and create the PathInfo object. Some, but potentially more of this can be extracted into helper functions in a shared crate, and then be used from both TvixStoreIO in tvix-cli as well as the tvix-store CLI entrypoint.

There was a NixHash::new() before, which didn't perform any validation of the digest length. We had some length validation when parsing nix hashes or SRI hashes, but some places didn't perform validation and/or constructed the struct directly. Replace NixHash::new() with a `impl TryFrom<(HashAlgo, Vec<u8>)> for NixHash`, which does do this validation, and update constructing code to use that, rather than populating structs directly. In some rare cases where we're sure the digest length is correct we still populate the struct manually. Fixes b/291.

2023-06-30 r/6368 fix(tvix/store/fuse): revert "implement open explicitly"Florian Klink1-72/+30
This reverts commit f5e291cf8328096d790f5416cf1968cb9164220a. The offsets are relative to the start of the file, and as long as we don't have BlobReaders implement seek, this will be very annoying to deal with.

2023-06-30 r/6367 fix(tvix/store/blobservice): write into hasher from b, not bufFlorian Klink2-2/+2
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.

2023-06-30 r/6366 feat(tvix/store/fuse): implement open explicitlyFlorian Klink1-30/+72
This moves from stateless I/O to actually dealing with file handles, allowing the filesystem to keep reusing existing blobreaders, instead of opening a new reader on every read() call.

2023-06-20 r/6337 feat(tvix/store/fuse): initial implementationFlorian Klink5-2/+1804
This is a first implementation of a FUSE filesystem, mounting tvix-store to a given location. This is mostly meant as one additional lens into a store, and could be used for builds. It's not meant to be used as a general-purpose thing. It still has some rough edges: - It doesn't implement open/close, so it doesn't use file handles. Which means, we need to open blobs for partial reads over and over again. - It doesn't implement seek, as BlobReader doesn't implement seek yet. - It doesn't track "lifetimes" of inodes by listening on forget, meaning it might hold more data in memory than necessary. - As we don't have store composition (and a caching layer) yet, operations might be slow.
