2024-05-11 r/8103 refactor(tvix/store): drop calculate_nar from PathInfoServiceFlorian Klink1-16/+0
This shouldn't be part of the PathInfoService trait. Pretty much none of the PathInfoServices do implement it, and requiring them to implement it means they also cannot make use of this calculation already being done by other PathInfoServices. Move it out into its own NarCalculationService trait, defined somewhere at tvix_store::nar, and have everyone who wants to trigger nar calculation use nar_calculation_service directly, which now is an additional field in TvixStoreIO for example. It being moved outside the PathInfoService trait doesn't prohibit specific implementations to implement it (like the GRPC client for the `PathInfoService` does. This is currently wired together in a bit of a hacky fashion - as of now, everything uses the naive implementation that traverses blob and directoryservice, rather than composing it properly. I want to leave that up to a later CL, dealing with other parts of store composition too.

This introduces rstest-based tests. We also add fixtures for creating some BlobService / DirectoryService out of thin air. To test a PathInfoService, we don't really care too much about its internal storage - ensuring they work is up to the castore tests.

2023-12-22 r/7256 chore(tvix): move store/fs to castore/fsFlorian Klink1-0/+6
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.

2023-11-19 r/7038 feat(tvix/store/pathinfoservice): implement NixHTTPPathInfoServiceFlorian Klink1-0/+2
NixHTTPPathInfoService acts as a bridge in between the Nix HTTP Binary cache protocol provided by Nix binary caches such as cache.nixos.org, and the Tvix Store Model. It implements the [PathInfoService] trait in an interesting way: Every [PathInfoService::get] fetches the .narinfo and referred NAR file, inserting components into a [BlobService] and [DirectoryService], then returning a [PathInfo] struct with the root. Due to this being quite a costly operation, clients are expected to layer this service with store composition, so they're only ingested once. The client is expected to be (indirectly) using the same [BlobService] and [DirectoryService], so able to fetch referred Directories and Blobs. [PathInfoService::put] and [PathInfoService::nar] are not implemented and return an error if called. This behaves very similar to the nar-bridge-pathinfo code in nar-bridge, except it's now in Rust.

2023-11-15 r/7014 refactor(tvix/store): remove from_url from PathInfoService traitFlorian Klink1-17/+1
We don't gain much from making this part of the trait, it's still up to `tvix_store::pathinfoservice::from_addr` to do most of the construction. Move it out of the trait and into the specific *Service impls directly. This allows further refactorings in followup CLs.

2023-09-22 r/6629 refactor(tvix): move castore into tvix-castore crateFlorian Klink1-7/+12
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>

There's only one way to calculate NAR files, by walking through them. Things like caching such replies should be done closer to where we use these, composing NARCalculationService doesn't actually give us much. Instead, expose two functions, `nar::calculate_size_and_sha256` and `nar::writer_nar`, the latter writing NAR to a writer, the former using write_nar to only keeping the NAR size and digest.
