Events are put in a queue, sorted by next execution time There are no skipping of events for which execution time has already expired. This can be verified by looking at: bool Event_queue::get_top_for_execution_if_time() As Kristian pointed out, if there next execution time for an event put back in queue is lower than the current time, it's next execution time will be adjusted. However older events should be executed before this one. The next execution time is calculated in Event_queue_element::compute_next_execution_time(). Sorry, but this code is a bit complex so I don't have time to go into details now. However I am reasonable sure that there will be no starving of old events. I will fix the documentation to be more clear about this Regards, Monty _______________________________________________ discuss mailing list -- [email protected] To unsubscribe send an email to [email protected]
