2024-04-20 r/7988 feat(tvix/store/bin): upload paths concurrently in `copy`Florian Klink1-15/+53
We can speedup uploads further by not uploading all store paths sequentially, but in parallel. We still don't respect the reference graph, so nothing changed here.

2024-04-19 r/7979 refactor(tvix/castore): generalize store ingestion streamsConnor Brewster1-2/+5
Previously the store ingestion code was coupled to `walkdir::DirEntry`s produced by the `walkdir` crate which made it impossible to reuse ingesting from other sources like tarballs or NARs. This introduces a `IngestionEntry` which carries enough information for store ingestion and a future for computing the Blake3 digest of files. This allows the producer to perform file uploads in a way that makes sense for the source, ie. the filesystem upload could concurrently upload multiple files at the same time, while the NAR ingestor will need to ingest the entire blob before yielding the next blob in the stream. In the future we can buffer small blobs and upload them concurrently, but the full blob still needs to be read from the NAR before advancing.

2024-04-13 r/7900 feat(tvix/store/bin): add "copy" commandFlorian Klink1-0/+93
This allows copying individual store paths from the local /nix/store into tvix-store. As we don't support getting this information from Nix yet, we currently expect metadata to be provided externally: Nix' `exportReferencesGraph` feature contains pretty much all data we need for this. Expect a list of this information at a well-known key (`closure`, similar to nixpkgs' `pkgs/build-support/binary-cache/ default.nix`). We currently simply upload all store paths sequentially, without any parallelism or awareness in how the reference graph looks like. As long as the connected stores don't enforce this, this is fine, at least for now.

2023-12-22 r/7256 chore(tvix): move store/fs to castore/fsFlorian Klink1-7/+7
With the recent introduction of the RootNodes trait, there's nothing in the fs module pulling in tvix-store dependencies, so it can live in tvix-castore. This allows other crates to make use of TvixStoreFS, without having to pull in tvix-store. For example, a tvix-build using a fuse mountpoint at /nix/store doesn't need a PathInfoService to hold the root nodes that should be present, but just a list. tvix-store now has a pathinfoservice/fs module, which contains the necessary glue logic to implement the RootNodes trait for a PathInfoService. To satisfy Rust orphan rules for trait implementations, we had to add a small wrapper struct. It's mostly hidden away by the make_fs helper function returning a TvixStoreFs. It can't be entirely private, as its still leaking into the concrete type of TvixStoreFS. tvix-store still has `fuse` and `virtiofs` features, but they now simply enable these features in the `tvix-castore` crate they depend on. The tests for the fuse functionality stay in tvix-store for now, as they populate the root nodes through a PathInfoService. Once above mentioned "list of root nodes" implementation exists, we might want to shuffle this around one more time. Fixes b/341.

2023-09-25 r/6653 feat(tvix/store): Support listening on UNIX domain socketsConnor Brewster1-1/+4
This adds support for listening on UNIX domain sockets via the tokio-listener crate. The crate will automatically determine whether to start a TCP or UNIX domain socket server based on the listen address. Unfortunately, it's not compatible with tonic right out of the box so I added some wrapper types to implement the necessary traits to make things work. We should investigate upstreaming a `tonic` option to the tokio-listener crate which implements the relevant `tonic` traits. Example: ``` $ tvix-store daemon -l /run/tvix-store.sock INFO tvix_store: tvix-store listening on /run/tvix-store.sock $ tvix-store mount -l /mnt/tvix --blob-service-addr grpc+unix:///run/tvix-store.sock --directory-service-addr grpc+unix:///run/tvix-store.sock --path-info-service-addr grpc+unix:///run/tvix-store.sock $ ls /mnt/tvix ``` Change-Id: I91c4a4b0c5a177b3b90e6c01a4e5d263130e6bdb Reviewed-on: https://cl.tvl.fyi/c/depot/+/9429 Tested-by: BuildkiteCI Reviewed-by: flokli <flokli@flokli.de> Reviewed-by: raitobezarius <tvl@lahfa.xyz>

This adds a virtiofs daemon implementation which hooks into the existing tvix-store filesystem implementation that is used for FUSE. This allows adding the filesystem to a microvm without having to set up FUSE inside the guest.

2023-09-22 r/6629 refactor(tvix): move castore into tvix-castore crateFlorian Klink1-10/+13
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>

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.

2023-09-20 r/6622 refactor(tvix/store/fs): Separate FUSE and filesystem codeConnor Brewster1-2/+7
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 Brewster1-14/+18
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 Klink1-5/+16
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.

This enables the tokio `signal` feature, and registers a ctrl_c signal handler, which will use the unmount handle to unmount in case a ctrl-c signal is received. This avoids having disconnected mountpoints when Ctrl-C'ing a `tvix-store mount` invocation. In case the filesystem is unmounted externally (via `umount /path/to/ mountpoint`), the future is waiting for the signal is never resolved and the task is stopped.
