protoc-gen-go-grpc v1.5.1

Dependencies

• Removed replace directive (needed only for testing), since it is incompatible with go install (#7451).

protoc-gen-go-grpc v1.5.0

Security

• The generated function Register<Service>Server now panics if the Unimplemented<Service>Server struct is embedded in a way that would otherwise lead to runtime panics if an unimplemented method was called. Users are advised to ensure they are properly embedding the Unimplemented struct for their service, and to regenerate their proto files to confirm. (#7438)
  • Note: "Proper embedding" of the Unimplemented struct means either embedding the struct by value (preferred) or ensuring it is always initialized to a valid pointer. E.g.

struct MyServiceImpl {
	pb.UnimplementedMyServiceServer // embedded by value, not pointer
	// .. other struct fields ..
}

New Features

• Generated code for services will produce streaming method definitions using one of six different generic types (e.g. BidiStreamingServer or ClientStreamingClient) instead of producing complete interfaces and implementations for the streaming methods. This can be disabled by setting use_generic_streams_experimental=false. Please file a bug if you encounter any issues with this behavior. (#7387)

Bug Fixes

• A period (.) is added to the end of the service interface doc comment to comply with Godoc. (#7392)

protoc-gen-go-grpc v1.4.0

New Features

• Add an optional implementation of streams using generics (Experimental) (#7057)
  • The new use_generic_stream_experimental=true option will cause the gRPC codegen to use prebuilt generic types to implement client and server stream objects, rather than generating new types and implementations for every RPC method. We intend to transition this to the default behavior in the next release. Please test it and provide any feedback.
