2023-09-20 r/6621 refactor(tvix/store/fuse): Switch from fuser to fuse-backend-rsConnor Brewster1-1/+1
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.

2023-09-04 r/6550 refactor(tvix/{cli,store}): move TvixStoreIO to tvix-cli crateFlorian Klink1-2/+0
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.

2023-05-23 r/6177 refactor(tvix/store/directorysvc): move from Vec<u8> to B3DigestFlorian Klink1-0/+2
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 Klink1-3/+0
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.

This adds a function that consumes a [proto::node::Node] pointing to the root of a (store) path, and writes the contents in NAR serialization to the passed [std::io::Write]. We need this in various places: - tvix-store's calculate_nar() RPC method needs to render a NAR stream to get the nar hash, which is necessary to give things imported in the store a "NAR-based" store path. - communication with (remote) Nix (via daemon protocol) needs a NAR representation. - Things like nar-bridge, exposing a NAR/NARInfo HTTP interface need a NAR representation.
