Daniel P. Berrange 707781fe12 Only add the timer when a callback is registered ... The lifetime of the virDomainEventState object is tied to the lifetime of the driver, which in stateless drivers is tied to the lifetime of the virConnectPtr. If we add & remove a timer when allocating/freeing the virDomainEventState object, we can get a situation where the timer still triggers once after virDomainEventState has been freed. The timeout callback can't keep a ref on the event state though, since that would be a circular reference. The trick is to only register the timer when a callback is registered with the event state & remove the timer when the callback is unregistered. The demo for the bug is to run while true ; do date ; ../tools/virsh -q -c test:///default 'shutdown test; undefine test; dominfo test' ; done prior to this fix, it will frequently hang and / or crash, or corrupt memory		2011-12-19 11:08:25 +00:00
