grpc call generate coredump

[nanfengnan1]

Description

i want to frr capabilities. write a grpc client call, but coredump.

Version

frr-10.0

How to reproduce

#include #include #include <grpc/grpc.h> #include <grpcpp/create_channel.h> #include "frr-northbound.pb.h" #include "frr-northbound.grpc.pb.h"

void get_capbilites_callback(grpc::Status status) { if (status.ok()) { std::cout << "RPC call succeeded!" << std::endl; } else { std::cout << "RPC call failed: " << status.error_message() << std::endl; } }

int main() { frr::GetRequest request; frr::GetResponse reply; grpc::ClientContext context; grpc::Status status;

/* 
 * grpc api: create a grpc channel for tcp connect 
 *      param1: ip:port pair
 *      param2: authentication credentials
 *              grpc::InsecureChannelCredentials: unsecurity connect
 *              grpc::SslCredentials: ssl/tll connect and recommand
 */
auto channel = grpc::CreateChannel("10.8.126.131:50051",
                                 grpc::InsecureChannelCredentials());
auto stub = frr::Northbound::NewStub(channel);

#if 0 request.set_type(frr::GetRequest::ALL); request.set_encoding(frr::XML); request.set_with_defaults(true); request.add_path("/frr-interface:lib"); auto stream = stub->Get(&context, request);

std::ostringstream ss;
while (stream->Read(&reply))
  ss << reply.data().data() << std::endl;

status = stream->Finish();
assert(status.ok());
std::cout << "Interface Info:\n" << ss.str() << std::endl;

std::cout << "service name: " << frr::Northbound::service_full_name() << std::endl;

std::cout << "" << std::endl;^

#endif

frr::CreateCandidateRequest req_candidate;
frr::CreateCandidateResponse res_candidate;

status = stub->CreateCandidate(&context, req_candidate, &res_candidate);

assert(status.ok());
printf("create candidate, id: %u\n", res_candidate.candidate_id());


frr::GetCapabilitiesRequest req_cap;
frr::GetCapabilitiesResponse res_cap;

req_cap.InitAsDefaultInstance();

stub->GetCapabilities(&context, req_cap, &res_cap);

printf("frr_version: \"%s\"\n", res_cap.frr_version());
printf("support modules: %ld\n", res_cap.supported_modules_size());
printf("rollback_support: %d\n", res_cap.rollback_support());

}

g++ nrth_cpp_client.cc frr-northbound.grpc.pb.cc frr-northbound.pb.cc -o nrth_cpp_client -lgrpc++ -lprotobuf

hope to okay. i want to know if my function call error. hope to how to use frr grpc function call.
