Debugging grpc over unix domain socket

[Ganesh Sangle]

hello,

i am trying to debug using grpc over unix domain socket on linux.

the server (in c++) starts and creates the sockets and the Wait API call is waiting.

the client (in go) also connects fine:

conn, err := grpc.Dial("unix:///....)

if err != nil {

    /// ...

}

err is nil so i assume connection works fine. fwiw i use "nc" to connect to it and it works fine as well.

however, when making an rpc call, it returns "all SubConns are in TransientFailure".

how do i debug this ? any pointers will help. thanks.

the issue seems to be resolved by using grpc with "grpc.WithDialer" option (which then used a net.DialTimeout call to create the connection) in grpc.Dial call

Also, i needed to add an extra "/" to the absolute path, so a path line "unix:///var/run/xyz" would now become "unix:////var/run/xyz".
