2023-03-10 r/5923 chore(tvix/store): remove old implementationsFlorian Klink3-337/+0
These were implementing against the (more complicated) gRPC interface, for which we now have a wrapper. Change-Id: I0a8284493718ab99618a1d21a76df4d173edb899 Reviewed-on: https://cl.tvl.fyi/c/depot/+/8100 Reviewed-by: raitobezarius <tvl@lahfa.xyz> Tested-by: BuildkiteCI
2023-03-10 r/5917 feat(tvix/store): validate blob size in NARRendererFlorian Klink1-0/+101
Make sure the blob size in the current proto node matches what we get back from the blob backend. Change-Id: I939fa18f37c7bc86ada8a495c7be622e69ec47f8 Reviewed-on: https://cl.tvl.fyi/c/depot/+/8129 Tested-by: BuildkiteCI Reviewed-by: raitobezarius <tvl@lahfa.xyz>
2023-03-10 r/5916 refactor(tvix/store): don't use anyhow::Result<()> in testsFlorian Klink1-11/+6
It's much easier to just unwrap the TempDir::new() result. Change-Id: I7b05bc18f3146401e30e1cc2bb412503c5171a66 Reviewed-on: https://cl.tvl.fyi/c/depot/+/8128 Reviewed-by: raitobezarius <tvl@lahfa.xyz> Tested-by: BuildkiteCI
2023-03-10 r/5915 chore(tvix/store): move NAR rendering logic into Renderer structFlorian Klink2-111/+117
This moves the logic rendering NARs to a struct using the previously introduced, more granular BlobService, ChunkService and DirectoryService. Instead of passing them around to the helper functions, they're kept as members of a struct. Remove the async invocations in the nar_renderer tests, there's nothing async in here.

2023-03-10 r/5907 chore(tvix/store): move protos into separate mod.rsFlorian Klink4-577/+0
This allows adding more stuff into this namespace, from different files. Also move tests on proto-related code from src/tests to src/proto/tests.

2023-01-31 r/5794 feat(tvix/store): add write_nar functionFlorian Klink2-0/+268
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.

This provides a `Directory.nodes()` function, returning an iterator over all three node types in an ordered fashion. Change-Id: Ib98696c03a9db8b6c613d6e2bf5587c1ae35133f Reviewed-on: https://cl.tvl.fyi/c/depot/+/7955 Reviewed-by: tazjin <tazjin@tvl.su> Tested-by: BuildkiteCI

2023-01-21 r/5724 feat(tvix/store/directory): validate Directory and sizesFlorian Klink1-1/+61
This calls out to Directory::validate() for all received Directory messages, and also makes sure the sizes we refer a Directory message as matches the sizes that have been calculated.

2023-01-21 r/5723 feat(tvix/store/directory): deduplicate Directory messagesFlorian Klink1-0/+50
We can omit sending Directory messages to clients that have already been sent in the same stream. We can also omit storing a Directory message if we already have it - they're content-addressed anyways.
