Barklund's and Virding's spec states that character literals are represented by {integer, Line, L}. The copy-and-paste bug is fixed the description of the abstract format.

2016-05-25Use the -epmd_module flag consistentlyMagnus Henoch
If the -epmd_module flag has been specified on the command line, use that module to register and look up node names instead of the default, erl_epmd. Also document this option.
2016-05-25Add -start_epmd command line optionMagnus Henoch
Add a command line option that lets you disable automatic starting of epmd when starting a distributed node. This differs from the undocumented setting -no_epmd, in that it does not affect the starting of an erl_epmd process within erl_distribution: the newly started node will expect an epmd instance to have been started previously.

2016-05-24erts: Move tracer SecondTraceTerm to Opts mapLukas Larsson
The extra trace data has been moved to the opts map in order for the tracer to be able to distinguish inbetween extra trace data 'undefined' and no extra trace data. In the same commit all opts associations have been changed so that if the tracer should not use them, the key is left unassicated instead of being sent to undefined. This should be give a small performance gain and also makes the API easier to work with.

2016-05-16Remove the warning about using erlang:raise/3Björn Gustavsson
There is no good reason to say that erlang:raise/3 is only for debugging. Here is an example where it can be extremely useful: try do_something(Args) catch Class:Error -> Stack = erlang:get_stacktrace(), io:format("Args: ~p\n", [Args]), erlang:raise(Class, Error, Stack) That is, we can let it crash, but log additional useful information before crashing.

2016-05-11erts: Only allow remove from trace_status callbackLukas Larsson
Make it so that it is only possible to remove a tracer via returning remove from an erl_tracer. This limition is put in place in order to avoid a lot of lock checking and taking in various places, especially in regards to trace events happening on dirty schedulers.

- Termination of a process... - Modify trace flags of process... - Process info on process... - Register/unregister of name on process... - Set group leader on process... ... while it is executing a dirty NIF.

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().
