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

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.

* paulgray/inet_db_fix/PR-949/OTP-13470:
Fix start timestamp instead of time check
Allow to refresh resolver settings on startup
|
|
Use cerl:make_list/1 instead of a home-made make_list/1 to ensure that
literal lists are constructed as literals. In a future release, we
would like to forbid in the loader construction of literal lists using
instructions like:
put_list {atom,a} [] Dst
The proper way is:
move {literal,[a]} {x,0}
Also update the comment about "put_list Const [] Dst" in ops.tab.

In 1f0ae04d374, a complete register map was introduced in the %live
instructions thar are added by beam_utils:live_opt/1.
Use the register map to improve beam_utils:is_killed_block/2.

Update version of common_test for OTP-19
Update versions

Add missing modules to common_test.app.src

beam_jump fails to optimize the following:
jump 2
label 1
label 2
Since this situation is rare, instead of complicating beam_jump,
add the optimization to beam_peep. It will always succeed, since
adjacent labels have been coalesced.
|
|
This module is now in common_test.app, so it will be included in the
release which is upgraded from (and to).
|
|
This is done early so test of ct_release_test shall work.
|
|
Remove the unreachable instructions after a 'raise' instruction
(e.g. a 'jump' or 'deallocate', 'return') to decrease code size.
|
|
to let future nodes know that we can handle
NEW_PID_EXT, NEW_PORT_EXT and NEWER_REFERENCE_EXT.
|
|
|
|
|
|
Increase max number of messages sent to fill buffers.
|
|
|
|
* egil/fix-erl_interface-tests:
Remove forgotten line
|
|
|
|
|
|
Those clause are obsolete and never used by common_test.
|
|
The macro ?t is deprecated. Replace its use with 'test_server'.
|
|
* bjorn/kernel/rpc-pinfo/ERL-124/OTP-13460:
Update spec for rpc:pinfo/2
|
|
rpc:pinfo/2 is documented as a location-transparent version
of process_info/2. Therefore, it should be expected that
the spec would allow calls with an item list, for example:
rpc:pinfo(Pid, [initial_call,last_calls])
