2017-02-23Implement fallback for terminate/3Raimo Niskanen
2017-02-22Stop pampering with stacktracesRaimo Niskanen
2017-02-22Clean up timer handlingRaimo Niskanen
2017-02-07Remove event timer optimizationRaimo Niskanen
Handle the event timer more like other timers and do not optimize the odd case of combining an event timeout with inserting custom events, wich by definition cancels the event timeout.

2017-02-01Bugfix: callback mode not cached after code changeRaimo Niskanen
Fix lots of internal state updates just before termination that could cause crash reports confused about timers.

2016-10-26Optimize event timeoutRaimo Niskanen
Do not start an event timer unless there are no enqueued events.
2016-10-26Rework timeout handlingRaimo Niskanen
Handling of timers and timeouts has been cleaned up and generalized. Semantic change regarding state timeout zero: Previously if one state caused a state timeout zero and managed to stay in the same state to insert additional timeout zero(s) in the next state callback invocation, then there would be only one timeout zero event. The mindset was that the machine was faster then the timeout zero. This has changed with the mindset that all state callback invocations should be independent, so now the machine will get one state timeout zero event per started state timeout zero. Note that just using zero timeouts is fairly esoteric...

2016-04-21Modify code_change/4 to return CallbackModeRaimo Niskanen
Also move check of non-atom states in callback mode state_functions to where the state function is called. This gives homogenous diagnostics for state functions, code_change/4 and system_replace_state StateFun. Irregularities pointed out by James Fish.

2016-02-29Remove the remove_event action and all alikeRaimo Niskanen
Removing events from the internal queues is not necessary with the choosen semantics of the event queue vs. hibernate. In an early implementation it was possible by combining hibernate with e.g. postpone to get an event in the queue that you would not see before processing the postponed event, and therefore should you decide to cancel a timer it was essential to be able to remove that unseen event from the queue. With the choosen semantics you will have to postpone or generate an event for it to be in the event queue, and if you e.g. postpone a timeout event and then cancel the timer it is your mistake. You have seen the event and should know better than to try to cancel the timer. So, the actions: remove_event, cancel_timer, demonitor and unlink are now removed. There have also been some cleanup of the timer handling code.
