2016-06-15Add short sleep when killing slave nodesSiri Hansen
slave_SUITE:t_start_link somtimes fails when checking that a slave is dead. This commit add a short sleep before the check to allow the node to terminate.

2016-06-04Return callback module in supervisor format_statusJosé Valim
The previous implementation of supervisor:get_callback_module/1 used sys:get_status/1 to get the supervisor inner state and retrieve the callback module. Such implementation forbids any other supervisor implementation that has an internal state different than the #state{} record in supervisor.erl. This patch allows supervisors to return the callback module as part of the sys:get_status/1 data, no longer coupling the callback module implementation with the inner #state{} record. Notice we have kept the clause matching the previous sys:get_status/1 reply for backwards compatibility purposes.

2016-05-26Wait for process to die before next callSiri Hansen
gen_server_SUITE:start often fails since a call which is expected to give 'noproc' error instead gives 'stopped' error. This happens when the call is done before the process is really dead. To overcome this problem, we now wait for the process exit before doing the call.

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().

2016-05-04epp: Add the -error and -warning directivesBjörn Gustavsson
If one of several alternatives configurations are required for an Erlang module to compile, but none are available, it would be useful to give a nice error message. For example: -ifdef(CONFIG_A). %% Some code if A is true. -else. -ifdef(CONFIG_B). %% Some code if B is true. -else. -error("Neither CONFIG_A nor CONFIG_B are available"). -endif. -endif. If neither CONFIG_A nor CONFIG_B are defined, the error message will be: module.erl:10: -error("Neither CONFIG_A nor CONFIG_B are available"). That is basically the same behavior as for the #error directive in GCC. For symmetry with the -error directive, add the -warning directive to generate a compiler warning. For example: -ifdef(HAVE_COOL_FEATURE). %% Code if we have Cool Feature. -else. %% Inefficient fallback code. -warning("Using inefficient fallback"). -endif. If HAVE_COOL_FEATURE is not defined, the warning message will be: module.erl:8: Warning: -warning("Using inefficient fallback"). That is basically the same behavior as for the #warning directive in GCC. Conflicts: lib/stdlib/src/epp.erl lib/stdlib/test/epp_SUITE.erl
2016-05-04epp: Refactor expansion of header pathBjörn Gustavsson
scan_include_lib/4 uses a helper function find_lib_dir/1, which has a strange interface. It takes a string and returns a tuple. The caller must match the tuple and call fname_join/1 to obtain the desired result. I assume that the strange interface was not noticed because the function is only used in one place. Replace the find_lib_dir/1 with a new expand_lib_dir/1 function which does the entire job in one go. The new function is much easier to reuse in other places, which we might want to do in a future commit.
