2016-04-15erts: more logging in trace_bif_SUITE trace_bif_returnLukas Larsson
2016-04-15erts: Optimize tracer reload testLukas Larsson
Without off_heap message queue the GC of the tracer could take very long and thus delay the code:purge which would in turn allow the trace generator to generate a lot of more messages which would make the tracer GC for even longer etc etc. The time taken for the testcase could go up to as large as 10 seconds and use lots of memory.
2016-04-15erts: Add 'spawned' trace event to 'procs' trace flagLukas Larsson
OTP-13497 This trace event is triggered when a process is created from the process that is created.
2016-04-15erts: Fix end_per_testcase crash in local_trace_SUITELukas Larsson
2016-04-15erts: Remove fake schedule testcaseLukas Larsson
Tracing to port in non-smp now creates port tasks instead of calling directly to the port to fake schedule events don't exist any more.
2016-04-15erts: Extend process and port tracingLukas Larsson
This commit completes the tracing for processes so that all messages sent by a process (via nifs or otherwise) will be traced. The commit also adds tracing of all types of events from ports. When enabling tracing using erlang:trace, the 'all' flag now also enables tracing on all ports. OTP-13496
2016-04-15erts: Implement tracer modulesLukas Larsson
Add the possibility to use modules as trace data receivers. The functions in the module have to be nifs as otherwise complex trace probes will be very hard to handle (complex means trace probes for ports for example). This commit changes the way that the ptab->tracer field works from always being an immediate, to now be NIL if no tracer is present or else be the tuple {TracerModule, TracerState} where TracerModule is an atom that is later used to lookup the appropriate tracer callbacks to call and TracerState is just passed to the tracer callback. The default process and port tracers have been rewritten to use the new API. This commit also changes the order which trace messages are delivered to the potential tracer process. Any enif_send done in a tracer module may be delayed indefinitely because of lock order issues. If a message is delayed any other trace message send from that process is also delayed so that order is preserved for each traced entity. This means that for some trace events (i.e. send/receive) the events may come in an unintuitive order (receive before send) to the trace receiver. Timestamps are taken when the trace message is generated so trace messages from differented processes may arrive with the timestamp out of order. Both the erlang:trace and seq_trace:set_system_tracer accept the new tracer module tracers and also the backwards compatible arguments. OTP-10267

2016-04-14Mend beam_SUITE:packed_registers/1Björn Gustavsson
packed_registers/1 may have actually tested put_list/3 instructions with high register numbers at some time. Currently, the compiler will generate code that only uses low register numbers. Totally rewrite the test case. It is difficult to arrange so that put_list/3 uses three high register numbers, so we will use get_list/3 instructions with high register numbers.

2016-04-07erts: Add enif_send with NULL as msg envLukas Larsson
This is an optimization for reducing the number of heap fragments allocated when sending a message where the majority of the message payload is on the sending process' heap.
