2017-11-15erts: Put pending DistrEntry in separate listSverker Eriksson
2017-11-15Refactor auto_connect into an outline functionSverker Eriksson
and abort_pending_connection into own utility function.
2017-11-15erts: Keep magic ref to DistEntry in net_kernelSverker Eriksson
to make sure it's kept alive.
2017-11-15Remove faulty assertSverker Eriksson
Send may have failed, port exit with dist_entry cleaned up and then new pending connection with queued messages.
2017-11-15erts: Transcode tuple fallbacksSverker Eriksson
When finalizing outgoing distribution messages we transcode them into using tuple fallbacks if the receiver does not support bitstrings and export-funs. This can only happen if the message was first encoded toward a pending connection when the receiver was unknown. It's an optimistic approach optmimized for modern beam nodes, that expect real bitstrings and funs (since <R13). Only erl_interface/jinterface lack this support.
2017-11-15Add optimistic DFLAG_DIST_HOPEFULLY for pending connectionsSverker Eriksson
to avoid tuple fallbacks for export funs and bitstrings. ToDo: Re-encode if receiver turn out to be erl_interface/jinterface.

2017-11-15erts: Async auto-connect for monitor_nodeSverker Eriksson
Removed distribution_SUITE:applied_monitor_node as it seems to test apply of trapping BIF and monitor_node does not trap anymore.

* maint: Atomic reference count of binaries also in non-SMP Conflicts: erts/emulator/beam/erl_fun.c
2017-02-06Atomic reference count of binaries also in non-SMPRickard Green
NIF resources was not handled in a thread-safe manner in the runtime system without SMP support. As a consequence of this fix, the following driver functions are now thread-safe also in the runtime system without SMP support: - driver_free_binary() - driver_realloc_binary() - driver_binary_get_refc() - driver_binary_inc_refc() - driver_binary_dec_refc()

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

2016-02-24erts: Change erl_exit into erts_exitSverker Eriksson
This is mostly a pure refactoring. Except for the buggy cases when calling erlang:halt() with a positive integer in the range -(INT_MIN+2) to -INT_MIN that got confused with ERTS_ABORT_EXIT, ERTS_DUMP_EXIT and ERTS_INTR_EXIT. Outcome OLD erl_exit(n, ) NEW erts_exit(n, ) ------- ------------------- ------------------------------------------- exit(Status) n = -Status <= 0 n = Status >= 0 crashdump+abort n > 0, ignore n n = ERTS_ERROR_EXIT < 0 The outcome of the old ERTS_ABORT_EXIT, ERTS_INTR_EXIT and ERTS_DUMP_EXIT are the same as before (even though their values have changed).
