2024-03-24 r/7777 feat(tvix/castore): add rstest-based DirectoryService testsFlorian Klink1-0/+6
This creates test scenarios (using the DirectoryService trait) that we want all DirectoryService implementations to pass. Some of these tests are ported from proto::tests::grpc_directoryservice, which tested this on the gRPC interface (rather than the trait), some others ensure certain behaviour for which we only recently introduced general checking logic (through ClosureValidator). We also borrow some code related to setting up a gRPC DirectoryService client (connecting to a server exposing a in-memory DiretoryService) from castore::utils, this will be deleted once it's all ported over.

2024-03-03 r/7641 feat(tvix/castore): add HashingReader, B3HashingReaderFlorian Klink1-0/+2
HashingReader wraps an existing AsyncRead, and allows querying for the digest of all data read "through" it. The hash function is configurable by type parameter, and we define B3HashingReader.

2023-12-22 r/7256 chore(tvix): move store/fs to castore/fsFlorian Klink1-0/+4
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.

2023-11-15 r/7022 refactor(tvix/castore/tonic): make async, support wait-connect=?Florian Klink1-1/+1
This moves the sync `channel::from_url` to a async `tonic::channel_from_url`. It now allows connecting non-lazily if `wait- connect=1` is set in the URL params. Also, make the pingpong tests for blobsvc and directorysvc use the wait- connect=1 codepath.

2023-09-22 r/6629 refactor(tvix): move castore into tvix-castore crateFlorian Klink1-0/+15
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>
