this enables us to work with the "usual" environment tweaks (for
debugging and other purposes), without the need for any special
handling in nettester itself
... but this brings a lot of problems with it. The issue is that
we still have a sequential store and we do not know how we could
delete the one entry right in the middle of processing. I keep this
branch if we intend to move on with it - but for now I look into a
different solution...
support for enhancing probability of memory addressing failure by
using non-NULL default value for malloced memory (optional, only if
requested by configure option). This helps to track down some
otherwise undetected issues within the testbench and is expected
to be very useful in the future.
We are "abusing" the parser tests to test the TCP/UDP reception
handling. Thus we do not run the other tests through to an IPv4
only config. It acutally is not that parser that matters but rather
the hope to find some init issues when running with only a single
listening socket (in IPv6, we usually both have an IPv4 AND an IPv6
listening socket, what - as practice has shown - may hide listener
setup errors).
- bugfix: solved potential (temporary) stall of messages when the queue was
almost empty and few new data added (caused testbench to sometimes hang!)
- fixed some race condition in testbench
- added more elaborate diagnostics to parts of the testbench
- solved a potential race inside the queue engine
made shutdown more reliable by makeing sure that the main queue DA worker
is only cancelled if this is actually unavoidable. Also moved down the
deletion of rsyslogd's pid file to immediately before termination, so
that absence of the file is a proper indication that rsyslogd has
finished (in the past, e.g. the testbench accidently ran two intances
as the pid file was deleted too early). Also some improvments to the
testbench, namely to handle aborts more intelligently (but still not
perfect).
This was a result of an internal processing error if maximum field
sizes had been specified in the property replacer.
Also did some testbench improvements, including omstdout.
now only stream class is utilized. ttys, pipes and outchannel functionality
is currently disabled. But the testbench worked again. Cleanup needed, will
do this with next commit (it may break things and I like to have this
milestone here).
this permits us to keep a persistent test environment between
v4 and v5, most importantly using the same tools. As far as the
actual tests are concerned, some had issues. I had no time to check
if that was an issue with the test or an actual issue with the
v3/4 engine. Will do that at some later stage.
The imdiag module now can very effectively inject messages, which also
frees us from uncertainties of tcp reception and processing. All shell
script based tests have been modularized, what makes it far easier to
create new tests. Also, the test bench now executes more reliable and
much faster, because we can now rely on actual engine information where
we previously did just a dumb sleep.
