2016-05-10erts: Implement max_heap_size process flagLukas Larsson
The max_heap_size process flag can be used to limit the growth of a process heap by killing it before it becomes too large to handle. It is possible to set the maximum using the `erl +hmax` option, `system_flag(max_heap_size, ...)`, `spawn_opt(Fun, [{max_heap_size, ...}])` and `process_flag(max_heap_size, ...)`. It is possible to configure the behaviour of the process when the maximum heap size is reached. The process may be sent an untrappable exit signal with reason kill and/or send an error_logger message with details on the process state. A new trace event called gc_max_heap_size is also triggered for the garbage_collection trace flag when the heap grows larger than the configured size. If kill and error_logger are disabled, it is still possible to see that the maximum has been reached by doing garbage collection tracing on the process. The heap size is defined as the sum of the heap memory that the process is currently using. This includes all generational heaps, the stack, any messages that are considered to be part of the heap and any extra memory the garbage collector may need during collection. In the current implementation this means that when a process is set using on_heap message queue data mode, the messages that are in the internal message queue are counted towards this value. For off_heap, only matched messages count towards the size of the heap. For mixed, it depends on race conditions within the VM whether a message is part of the heap or not. Below is an example run of the new behaviour: Eshell V8.0 (abort with ^G) 1> f(P),P = spawn_opt(fun() -> receive ok -> ok end end, [{max_heap_size, 512}]). <0.60.0> 2> erlang:trace(P, true, [garbage_collection, procs]). 1 3> [P ! lists:duplicate(M,M) || M <- lists:seq(1,15)],ok. ok 4> =ERROR REPORT==== 26-Apr-2016::16:25:10 === Process: <0.60.0> Context: maximum heap size reached Max heap size: 512 Total heap size: 723 Kill: true Error Logger: true GC Info: [{old_heap_block_size,0}, {heap_block_size,609}, {mbuf_size,145}, {recent_size,0}, {stack_size,9}, {old_heap_size,0}, {heap_size,211}, {bin_vheap_size,0}, {bin_vheap_block_size,46422}, {bin_old_vheap_size,0}, {bin_old_vheap_block_size,46422}] flush().

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.
