This sets the maximum queue size for the IP trace driver which is used
when tracing to shell and/or <c>{local,File}</c>.
Also, change the default queue size set by dbg:trace_port/2 to 200.
|
|
When using an IP trace client, turn of all trace flags on the client
port to avoid massive overload. Note that this is only a protection on
client start - it is currently not possible to protect the port
against trace flags set at a later point in time.

i.e enable all send/receive trace.
|
|
To set/clear match specs for send and receive trace.
'e' for Event as we might want to add match specs
for other trace events (proc exit,link,ulink,...).

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.

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.

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, ..}.

This flag, which silences call trace, can be set with erlang:trace/3,
but was not allowed in dbg:p/2. This has been corrected.

Earlier dbg:stop only did erlang:trace_delivered and did not flush the
trace file driver. Therefore there could still be trace messages that
were delivered to the driver (guaranteed by erlang:trace_delivered)
but not yet written to the file. This commit adds this flushing on
each node before the dbg process terminates.

Support monitoring and demonitoring from driver threads
Fix further test-suite problems
Correct the VM to work for more test suites

Rewrite trace code and external coding. Also slightly correct
the interface to the match-spec engine to make tracing work.
That will make the test suites runnable.
