Default build pulls zero gRPC code; rebuild with `-tags=grpc` to opt
into gRPC.
Decomplected via a `grpcBackend` interface in `sdk/go/client` and a
`grpcSubClient` interface in `client/go`. The default build wires a
no-op backend (`*_nogrpc.go`); the `grpc` build wires the real
protobuf-backed client (`*_grpc.go`). Public methods stay the same in
both builds — the gRPC fast path is preferred when wired, else
JSON-RPC / WebSocket.
Files gated:
- pkg/grpc/pb/lxdex_grpc.pb.go (//go:build grpc)
- pkg/proto/engine/proto/lx_engine_grpc.pb.go (//go:build grpc)
Files refactored:
- sdk/go/client.go: //go:build grpc with stub in client_nogrpc.go
- sdk/go/client/client.go: gRPC removed from method bodies; backed by
the grpcBackend interface (grpc_backend{,_grpc,_nogrpc}.go)
- client/go/main.go: GrpcClient + ConnectGrpc moved to grpc.go
(//go:build grpc); nogrpc.go stubs ConnectGrpc with a clear error
Verification:
- go build ./... (default) clean across sdk/go, client/go, top-level
- go build -tags=grpc ./... clean across all three modules
- go test ./... and go test -tags=grpc ./... green
- go list -deps shows 0 google.golang.org/grpc packages in default
builds of sdk/go/client and client/go; 62 packages with -tags=grpc
READMEs in sdk/go and client/go document the build-tag opt-in.
