2019-06-27[snmp|agent] Dialyzer related changesMicael Karlberg
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. OTP-15932
2019-06-27[snmp] Dialyzer fixesMicael Karlberg
Make target (for running dialyzer on snmp), os usage and a minor snmp_log ("future proofing"). OTP-15932
2019-05-22[snmp] Remove use of the deprecated get_stacktrace functionMicael Karlberg
Removed the use of the deprecated erlang:stacktrace() function. Instead make use of the 'catch Class:Error:Stacktrace' feature. OTP-15332
2019-04-15[snmp|agent] Fix typesMicael Karlberg
There no timestamp type in os (but there is in erlang).
2019-04-11[snmp|agent|test] Timestamps and test managerMicael Karlberg
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.
2019-04-11[snmp|agent|test] Agent test manager start fixMicael Karlberg
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).

2018-09-07[snmp] Improved Audit Trail Log conversion failureMicael Karlberg
If conversion of an Audit Trail Log (ATL) entry failed, this could result in an abort of the entire conversion, not just the one entry. This has now been improved so that the failure now results in a "error message" into the "stream". Furthermore, we now keep track of the number of entries we succeede and fail to convert.

2013-10-31[snmp] Improving ATL handling of corrupt logsMicael Karlberg
When converting an Audit Trail Log to text a corrupt log entry could cause the entire conversion to fail. Also, for a log with sequence numbers, failing to decode a log entry would cause the conversion to fail (not because of the failed decode, but because of the failure to write the error message).

2013-10-11[snmp] Add (atl) log conversion block optionMicael Karlberg
It is now possible to request that the Audit Trail Log should be blocked during conversion (log_to_txt or log_to_io). This could be usefull when coverting a large log (when there is a chance it may otherwise wrap during conversion).
