2024-10-11 r/8787 refactor(tvix/store): use strictly typed PathInfo structMarijan Petričević1-0/+29
This switches the PathInfoService trait from using the proto-derived PathInfo struct to a more restrictive struct, and updates all implementations to use it. It removes a lot of the previous conversion and checks, as invalid states became nonrepresentable, and validations are expressed on the type level. PathInfoService implementations consuming protobuf need to convert and do the verification internally, and can only return the strongly typed variant. The nix_compat::narinfo::NarInfo conversions for the proto PathInfo are removed, we only keep a version showing a NarInfo representation for the strong struct. Converting back to a PathInfo requires the root node now, but is otherwise trivial, so left to the users.

2024-08-13 r/8484 refactor(tvix/castore): use Directory struct separate from proto oneYureka1-1/+0
This uses our own data type to deal with Directories in the castore model. It makes some undesired states unrepresentable, removing the need for conversions and checking in various places: - In the protobuf, blake3 digests could have a wrong length, as proto doesn't know fixed-size fields. We now use `B3Digest`, which makes cloning cheaper, and removes the need to do size-checking everywhere. - In the protobuf, we had three different lists for `files`, `symlinks` and `directories`. This was mostly a protobuf size optimization, but made interacting with them a bit awkward. This has now been replaced with a list of enums, and convenience iterators to get various nodes, and add new ones.

2024-03-28 r/7795 refactor(tvix/castore/*): drop utils.rs and grpc directorysvc testsFlorian Klink1-2/+0
This drops pretty much all of castore/utils.rs. There were only two things left in there, both a bit messy and only used for tests: Some `gen_*_service()` helper functions. These can be expressed by `from_addr("memory://")`. The other thing was some plumbing code to test the gRPC layer, by exposing a in-memory implementation via gRPC, and then connecting to that channel via a gRPC client again. Previous CLs moved the connection setup code to {directory,blob}service::tests::utils, close to where we exercise them, the new rstest-based tests. The tests interacting directly on the gRPC types are removed, all scenarios that were in there show now be covered through the rstest ones on the trait level.

2023-09-22 r/6629 refactor(tvix): move castore into tvix-castore crateFlorian Klink1-0/+4
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>
