support for gRPC ? about goleak

[prashantv]

Did you close the gRPC connection?

As per the example at https://grpc.io/docs/tutorials/basic/go.html

conn, err := grpc.Dial(*serverAddr)
if err != nil {
    ...
}
defer conn.Close()

Yes, i close the gRPC connection, this is strange.

You can find a sample of my small test below (WithBearerToken just put a JWT token for auth).

func TestListAddresses(t *testing.T) {
	ctx := WithBearerToken(context.Background(), "AUTO_LOGIN")
	client, conn := getgRPCClient()
	defer conn.Close()

	_, err := client.ListAddresses(ctx, &pb.ListAddresses{})
	if err != nil {
		t.Fatalf("error getting addresses : %v", err)
	}
}

Ok, i think i find my issue, it's due to opencensus trace/stats. I will look a little bit in depth.

	conn, err := grpc.Dial("srv",
		grpc.WithStatsHandler(&ocgrpc.ClientHandler{}),
		grpc.WithTransportCredentials(tlsCreds),
	)
