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().

2016-05-09mnesia_ext: Create table/data containers from mnesia monitor not temporary ↵Dan Gudmundsson
processes Tables or data containers should be owned and monitored by mnesia_monitor and should thus be created by that process. Always create_table before loading it We need to create tables for ram_copies at least before loading them as they are intermittent. It is also needed to get mnesia monitor as the parent and supervisor of the data storage.
2016-05-09mnesia_ext: Implement ext copies indexUlf Wiger
Make ram_copies index always use ordered_set And use index type as prefered type not a implementation requirement, the standard implmentation will currently ignore the prefered type.

2016-05-09syntax_tools: Add support for types and specsHans Bolinder
In particular, types and specs can be pretty-printed. There are issues with macros (left behind by epp_dodger). Typed record fields are handled. Fields are represented by triples instead of two-tuples, which is an incompatible change. Some attributes (-export_type, -spec, -type, &c) have been given meaning in recent time, but the set of wild attributes (see Barklund's spec) is not changed.
