2016-10-12erts: Refactor out func_info into structLukas Larsson
This commit adds two new structs to be used to represent erlang code in erts. ErtsCodeInfo is used to describe the i_func_info header that is part of all Export entries and the prelude of each function. This replaces all the BeamInstr * that were previously used to point to these locations. After this change the code should never use BeamInstr * with offsets to figure out different parts of the func_info header. ErtsCodeMFA is a struct that is used to descripe a MFA in code. It is used within ErtsCodeInfo and also in Process->current. All function that previously took Eterm * or BeamInstr * to identify a MFA now use the ErtsCodeMFA or ErtsCodeInfo where appropriate. The code has been tested to work when adding a new field to the ErtsCodeInfo struct, but some updates are needed in ops.tab to make it work.

2016-07-05run_erl: Fix failing run_erl invokation on OpenBSDSverker Eriksson
Symptom: run_erl does exit(0) and child program (erl) does not seem to start. Running run_erl again however brings the previous child program to life. Problem: A race causing run_erl to read 0 from master pty and exit because the child has not yet opened its corresponding slave pty. Solution: Use the non standard openpty() function instead that does not expose this race as the slave fd is opened in the parent. Question: Is there a race free way to do this with posix_openpt on OpenBSD?

2016-06-01Don't kill old erlang if HEART_NO_KILL is setSimon Cornish
If the environment variable HEART_NO_KILL is set then heart won't kill the old erlang process. This is desirable if the command executed by heart takes care of this.

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.

2016-05-10erts: 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().

that uses its own super carrier (erts_exec_mmapper) to guarantee low addressed and executable memory (PROT_EXEC). Currently only used on x86_64 that needs low memory for HiPE/AMD64's small code model. By initializing erts_exec_mapper early we secure its low memory area before erts_literal_mmapper might steal it.

On MacOS X, defining _XOPEN_SOURCE usually *removes* features from header files. Therefore, we should not set _XOPEN_SOURCE to 600 since that will remove the prototype for vsyslog(). Setting it to an empty value or not including it will ensure that the vsyslog() prototype is included.

Except it cannot be disabled and cannot be multi-threaded. The bit-vector 'erts_literal_vspace_map' on 32-bit is currently only protected by the literal allocator mutex. We could allow multiple instances on 64-bit (I think), but what would be the point?
