2017-05-18Make lock counter info independent of the locks being countedJohn Högberg
This allows us to enable/disable lock counting at will, and greatly improves the performance of erts_debug:lock_counters/1 since we no longer have to worry about the lock counters "dying" while we're enumerating them. OTP-14412

2017-05-10erts: Fix ets:select_replace with {const, NewTuple}Sverker Eriksson
Enable ets:select_replace to do a generic single object compare-and-swap operation of any ets-tuple using a matchspec like this: [{Old, [], [{const, New}]}] The only exception when this does not work is if the key contains maps or atoms looking like variables (like '$1').

2017-05-05erts: the esdp is not always available in matchspecLukas Larsson
This happens for instance when a receive_trace is run in the sys_msg_dispatcher thread when the trace_delivered trace message is traced.
2017-05-05Clear p->fvalue when handling a try/catchBjörn Gustavsson
p->fvalue will be set by BIFs that generate exceptions (such as throw/1), and it will not be cleared before another exception is generated. Potentially, p->fvalue may contain a huge term (e.g. after throw(HugeTerm)) which will be kept in the heap. We can shorten the lifetime of f->value by clearing it in the instructions that handle catches: catch_end and try_end. That is safe because BEAM code will never access p->fvalue. If BEAM code needs to rethrow an exception it will use a reference to the value passed in an X register. The reason that p->fvalue must not be cleared already in handle_error() is that native code trap handlers will use it. (See the comment before handle_error() and the comment at the end of handle_error() in beam_emu.c for some more information about exception handling.)
2017-05-04erts: Fix code:is_module_native for local traceSverker Eriksson
Local trace on first function in module made code:is_module_native/1 return true. Use new erts_is_function_native() to make a proper check.

The previous code worked through luck because the memory returned from erts_alloc was zero:ed and SCHED_NORMAL is 0. But if you run with +Meamin that is not always the case which is how this error was detected.

Minimum known timeout position is saved in bot far and near wheel. This information is used to avoid scanning from current position in the cases were we know the minimum timeout position.

The old single wheel implementation handled about 65 seconds. The new dual wheel implementation handles more than 37 hours. The dual wheels have also been shrunk compared to the single wheel, so the total memory consumption for timer wheels have been cut in half.
