This provides a Nix HTTP Binary Cache interface in front of a tvix-store that's reachable via gRPC. TODOs: - remove import command, move serve up to toplevel. We have nix-copy- closure and tvix-store commands. - loop into CI. We should be able to fetch the protos as a third-party dependency. - Check if we can test nar-bridge slightly easier in an integration test. - Ensure we support connecting to unix sockets and grpc+http at least, using the same syntax as tvix-store. - Don't buffer the entire blob when rendering NAR Co-Authored-By: Connor Brewster <cbrewster@hey.com> Co-Authored-By: Márton Boros <martonboros@gmail.com> Co-Authored-By: Vo Minh Thu <noteed@gmail.com> Change-Id: I6064474e49dfe78cea67676957462d9f28658d4a Reviewed-on: https://cl.tvl.fyi/c/depot/+/9339 Tested-by: BuildkiteCI Reviewed-by: tazjin <tazjin@tvl.su>
