[PATCH 01/11] Process all pending I/O for a RPC client before checking EOF

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: "Daniel P. Berrange" <berrange@xxxxxxxxxx>

In the socket event handler for the RPC client we must deal
with read/write events, before checking for EOF, otherwise
we might close the socket before we've read & acted upon the
last RPC messages
