This bug was introduced in R16B. Testcases have been adapted to
verify the correct behaviour.

Must receive 'abort' even after loop_runner has finished.

Add erlang:system_info(tolerant_timeofday), an API to check whether
compensation for sudden changes of system time is enabled or not.

as it times out on some machines.
Not much point in redoing with lower input reductions when the terms
are so big we will trap several times anyway.

|
* bjorn/erts/fix-lingering-tracer:
Teach the call_time trace to notice when the trace dies (non-SMP system)
|
|
The call_time trace is a special kind of tracing that requires
a tracer process just like ordinary call trace, but it never
actually sends anything to the tracer. It merely use the existence
of a trace process (and call trace flags) as an indication that
call_time tracing is active for the process.
If the tracer dies in a non-SMP run-time system, processes with
call_time tracing would not notice that the tracer had
died. Furthermore, if the set_on_spawn flag was active, the dead
tracer could be propagaged to newly spawned processes.
Before accumulating trace information in a non-SMP system, always
validate the tracer process. (In an SMP system, a reference to a
dead tracer will be cleared away each time a process is scheduled.)
While we could put all of the new code beam_bp.c, we have chosen to
make a function call from beam_bp.c to a function in erl_trace.c for
clarity's sake and to ease further maintenance. In the future, we
might want to handle tracing in more similar ways in the SMP and
non-SMP system.

to be: 116,Arity, K1,V1,K2,V2,...,Kn,Vn
instead of: 116,Arity, K1,K2,...,Kn, V1,V2,....,Vn
We think this will be better for future internal map structures
like HAMT. Would be bad if we need to iterate twice over HAMT
in term_to_binary, one for keys and one for values.

The expression,
#{} =:= M
where M was any Map, would always result in 'true'.
This commit fixes this issue by first comparing sizes for
both terms and then checking for size zero.

* vinoski/ds2:
further enhancements for dirty schedulers
allow optional whitespace in dirty scheduler erl options
|
|
Add support for setting the number of dirty CPU schedulers online via
erlang:system_flag/2. Assuming the emulator is built with dirty schedulers
enabled, the number of dirty CPU schedulers online may not be less than 1,
nor greater than the number of dirty CPU schedulers available, nor greater
than the number of normal schedulers online. Dirty CPU scheduler threads
that are taken offline via system_flag/2 are suspended. The number of dirty
CPU schedulers online may be adjusted independently of the number of normal
schedulers online, but if system_flag/2 is used to set the number of normal
schedulers online to a value less than the current number of normal
schedulers online, the number of dirty CPU schedulers online is decreased
proportionally. Likewise, if the number of normal schedulers online is
increased, the number of dirty CPU schedulers online is increased
proportionally. For example, if 8 normal schedulers and 4 dirty CPU
schedulers are online, and system_flag/2 is called to set the number of
normal schedulers online to 4, the number of dirty CPU schedulers online is
also decreased by half, to 2. Subsequently setting the number of normal
schedulers online back to 8 also sets the number of dirty CPU schedulers
online back to 4. Augment the system_flag/2 documentation in the erlang man
page to explain this relationship between schedulers_online and
dirty_cpu_schedulers_online.
Also ensure that all dirty CPU and I/O schedulers are suspended when
multi-scheduling is blocked via system_flag/2, and brought back online when
multi-scheduling is unblocked.
Add Rickard Green's rewritten check_enqueue_in_prio_queue() function that
inspects process state more thoroughly to determine if to enqueue it and if
so on what queue, including dirty queues when appropriate.
Make sure dirty NIF jobs do not trigger erlang:system_monitor long_schedule
messages.
Add more dirty scheduler testing to the scheduler test suite.
Remove the erts_no_dirty_cpu_schedulers_online global variable, since it's
no longer needed.
Execute dirty NIFs on a normal scheduler thread while multi-scheduling
blocking is in effect. Evacuate any dirty jobs residing in the dirty run
queues over to a normal run queue when multi-scheduling is blocked.
Allow dirty schedulers to execute aux work.
Set the dirty run queues halt_in_progress flag when halting the normal
schedulers.
Change dirty scheduler numbers to a structure including both scheduler
number and type, either dirty CPU or dirty I/O. Add some assertions to
ensure that dirty CPU schedulers operate only on dirty CPU scheduler
process flags, and the same for dirty I/O schedulers.

This change was triggered by the OSE float printing function
not working exactly the same way as linux/win32. But it is
also a good one in general as it cuts size in more than half
for floats.

Faulty test for maps update

..has been successfully called.
Opened resource types (created or taken-over) were left "hanging"
leading both to memory leakage and other more strange and serious behavior.
Now a proper rollback is done.
