I'm looking at a bug which appears to come down to: some of my event
callbacks deallocate events, bufferevents, and/or their callback data.
Under difficult-to-reproduce circumstances, libevent appears to queue up
calls to my callbacks (possibly implicitly via internal control flow),
and call them even though the associated events and data have been
deallocated. I wish to apply a large hammer to this problem: delay
deallocations until after all queued-up callbacks have been processed,
but before libevent asks the OS for the next batch of events.
I *think* this can be done with a timer event which is assigned a lower
priority than all other events in the program, and which is
event_add()ed with an immediate timeout whenever there are deallocations
pending.
Will this work?
Is there a better way to do this?
Thanks,
zw
