I am trying to make a robust clientReader and am having problems in the
case, where the client comes up before the server. See below for the
important code. So if I start the client more than a second before than the
server, the WaitForConnected deadline passes, and GetState() returns
GRPC_CHANNEL_TRANSIENT_FAILURE,
and subsequent calls of WaitForConnected() does not actually wait, and
GetState gets stuck at GRPC_CHANNEL_CONNECTING, even after server finally
does come up. So do I need to reset the channel, or what to get it to
actually connect?
Thanks.
