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.

Improved test printouts (more with timestamps), also
fixed the printouts of the (fake) local-db start
result printout.
Also updated the copyright end-dates.

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).

Improve debug (verbose) printouts when a get/get-next/get-bulk/set
request fails (first by printing at level log instead of trace
and secondly by also printing the original operation result
when the operation fails).

Added VMODULE for the two new modules.
Also, improved some verbose printouts.

Added the Extra (net-if data) argument to all the get-
mechanism callback functions.
OTP-15691
|
|
Added the snmpa_get module as the default get-mechanism
for the agent.
This has been done by simply moving the do_get, do_get_next
and do_get_bulk functions from the snmpa_agent module.
Some functions where also moved into the lib module (with
the idea of beeing more generally useful).

Added preliminary version of the get-mechanism behaviour.

Add/update and export some useful types.

Fixed the build order. Some of the mib modules export types
used by other modules, so build them (the mib-modules) first
(after snmpa).

Also streamlined the config storage. And corrected
the store of the set_mechanism (in the snmp_agent_table).
This is only used for debugging, but just the same.

For some outgoing messages (not response) the following
error(s) has been corrected:
* encrypted: logged incorrectly, should have written the v3-header
and the scoped pdu, but was actually logged as-is (encrypted),
making conversion impossible.
* un-encrypted: messages was not logged at all.

I did not find any legitimate use of "can not", however skipped
changing e.g RFCs archived in the source tree.

In the future, erlang:get_stacktrace/0 will probably only work
inside a the 'catch' block of a 'try' expression.
Future-proof the code by rewriting the old-style catch to
a try...catch.

The original patch also suggested the following fix.
However we need more information to be able to understand if
this is correct or not, and it does not have priority at the moment
for us to investigate.
