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

2016-02-02erts: Add microstate accountingLukas Larsson
Microstate accounting is a way to track which state the different threads within ERTS are in. The main usage area is to pin point performance bottlenecks by checking which states the threads are in and then from there figuring out why and where to optimize. Since checking whether microstate accounting is on or off is relatively expensive if done in a short loop only a few of the states are enabled by default and more states can be enabled through configure. I've done some benchmarking and the overhead with it turned off is not noticible and with it on it is a fraction of a percent. If you enable the extra states, depending on the benchmark, the ovehead when turned off is about 1% and when turned on somewhere inbetween 5-15%. OTP-12345
2016-01-28Use file read buffering in dbg:trace_clientPéter Gömöri
Trace files are typically large but contain small terms so we can expect a performance gain from read buffering. dbg:trace_client with a dummy handler ran more then 3x faster on a sample 200MB trace file. fprof:profile can also gain a bit.

* fishcakez/runtime_tools/dbg/OTP-12517: Ensure dbg tracer exits when dbg is stopped
2015-02-26Ensure dbg tracer exits when dbg is stoppedJames Fish
Previously the tracer might receive an 'EXIT' message in the trace receive loop and treat it as garbage. Test uses a custom dbg process handler to reliably recreate the race condition, i.e. the message order {trace, ..}, {'EXIT, ..}.

2014-03-20Introduce runtime_dependencies in .app filesRickard Green
Most dependencies introduced are exactly the dependencies to other applications found by xref. That is, there might be real dependencies missing. There might also be pure debug dependencies listed that probably should be removed. Each application has to be manually inspected in order to ensure that all real dependencies are listed. All dependencies introduced are to application versions used in OTP 17.0. This since the previously used version scheme wasn't designed for this, and in order to minimize the work of introducing the dependencies.

Until this is reference counted it may interfere with other applications. The performance loss should (according to the implementor) be negligible with it always on.
