[snmp|agent] Dialyzer related changes

2019-06-27T15:50:57+00:00

Changes to satisfy dialyzer. Including changing the definition
of some of the behaviours (use the '-callback' attribute instead
of an explicit behaviour_info/1 function).

Also found and corrected some (apparently minor) bugs.

[snmp] Remove use of the deprecated get_stacktrace function

Removed the use of the deprecated erlang:stacktrace() function.
Instead make use of the 'catch Class:Error:Stacktrace' feature.

There no timestamp type in os (but there is in erlang).

[snmp|agent|test] Timestamps and test manager

2019-04-11T16:55:44+00:00

Added common (formated) timestamp function(s). Made use of
these in the verbosity module (for debug printouts) and in
the test suite(s).

I also *think* I found the cause for some if the test case
failures (timeouts).
For v3 (agent) test cases the test manager makes use of parts
of the agent code: snmp_framework_mib and snmp_user_based_sm_mib.
And since they store their data in snmpa_local_db, that also
needs to be running.
And this was the problem (I think). On some (slow) machines,
the snmpa_local_db process from the *previous* test case
might still be running when the we tried to start it. That meant
that no new snmpa_local_db was started. Instead the old one,
still running but terminating, was retain. For a while. Until
it actually finally stopped. So the next operation towards
snmpa_local_db, insert, simply hanged until the process
terminated.
This in combination with the fact that the packet server process,
which was started using proc_lib, previously called init_ack
before this init was actually done, could actually start and then
at a much later time hang because some operation timed out
(the packet server was hanging).

Yuckety yuck-yuck.

[snmp|agent|test] Agent test manager start fix

2019-04-11T16:55:44+00:00

The agent test manager had a bug during start that could
potentially cause deadlock, but atleast could cause test
cases to fail because of timeouts. The test manager
(actually the "packet server") used proc_lib to start the
process but it called the init_ack function before the init
was actually complete. This was only a problem for v3 cases
(where it did a bunch of further inits, including starting
the local-db process).

Also did debug/verbosity tweaking. Added a bunch of debug
(verbosity) printouts for the agent test manager "packet server"
during v3 init. Also made sure we could distinguish the
"normal" local-db from the one used by the test manager
(this is done by using a new short-name).

[snmp] Add proper version
