Package ganeti :: Module daemon :: Class AsyncAwaker

Class AsyncAwaker

A way to notify the asyncore loop that something is going on.

If an asyncore daemon is multithreaded when a thread tries to push some data to a socket, the main loop handling asynchronous requests might be sleeping waiting on a select(). To avoid this it can create an instance of the AsyncAwaker, which other threads can use to wake it up.
