When the error
[Errno 32] Broken pipe
occurs after the connection has been idle, the connection checksubstrate.websocket.connected
andsubstrate.websocket.sock
still returnTrue
.In order to get the real connection state, I used a low-level socket check via
substrate.websocket.sock.getsockopt(socket.SOL_SOCKET, socket.SO_ERROR)
.Also, I've fixed and new tests.
