* some more fixes for queue engineRainer Gerhards2009-05-281-0/+1
| | | | The enhanced testbench now runs without failures, again
* solved design issue with queue terminationRainer Gerhards2009-05-261-3/+29
| | | | | | | | | | | ... and also improved the test suite. There is a design issue in the v3 queue engine that manifested to some serious problems with the new processing mode. However, in v3 shutdown may take eternally if a queue runs in DA mode, is configured to preserve data AND the action fails and retries immediately. There is no cure available for v3, it would require doing much of the work we have done on the new engine. The window of exposure, as one might guess from the description, is very small. That is probably the reason why we have not seen it in practice.
* improved testbench / solved imdiag race conditionRainer Gerhards2009-05-251-0/+43
imdiag/imtcp had a modload race condition (as imdiag is a testing aid, this has no implications for production deployments). Also, I replaced netcat by a custom program to talk to imdiag. This, for the first time ever, is now a Java program. I plan to add some GUI troubleshooting tools and thought it is a good idea to start doing things in Java that can simply be done in that language.
