The proto directory contains protocol buffer definitions for the messaging format used in communication over the gRPC and dRPC channels. For information on using protobuf tools for development see here.
When modifying these files, make sure to update all generated files. Relevant files can be generated with commands listed below issued from within the src/proto top level directory of DAOS source:
-
Files generated for the control plane in
src/controlwill be in Golang and have the file extension.pb.go. Example command syntax:protoc -I mgmt --go_out=plugins=grpc:control/common/proto/mgmt mgmt/storage.proto -
Files generated for the data plane in other
srcsubdirectories will be in C and have file extensions.pb-c.[ch]. A third-party plugin protobuf-c is required to generate C language pb files. Example command syntax:protoc -I mgmt --c_out=../mgmt mgmt/srv.proto --plugin=/opt/potobuf/install/bin/protoc-gen-c
