rsyslog 8.31 - an important release

Today, we release rsyslog 8.31. This is probably one of the biggest releases in the past couple of years. While it also offers great new functionality, what really important about it is the focus on further improved software quality.

Let's get a bit down on it. First let's mention some important new features:

And then we have a set of several hundred commits concerned with improved software quality:
  • testbench dynamic tests have been extended
  • coverage of different compilers and compiler options has been enhanced
  • more modules are automatically scanned by static analysis
  • daily Coverity scans were added to the QA system, which have proofen to be a very useful addition
  • more aggressive and automated testing with threading debuggers (valgrind's helgrind and clang thread sanitizer) has been added, also with great success
  • as a result of these actions, we could find and fix many small software defects.
  • and there also have been some big and important fixes, namely for imjournal, omelasticsearch, mmdblookup and the rsyslog core
Many users were involved in finding and fixing bugs, many of which all I do know from is there github handle. So rather than highlighting just some of them, I would like to refer to the github milestone issue tracker where all can be found. My sincere thanks to everyone for all their support!

I consider rsyslog release 8.31 a major step forward in our QA policy. We already had improved quite a bit and the state was already pretty good. However, with the changes introduced in 8.31, we make a big step forward, into a kind of next-gen QA policy. Of course, QA is a journey and not a "do once" target. So expect more good stuff upcoming in the next releases. We are not done yet!

I would like to use this opportunity to express a personal "thank yo" to Thomas Deutschmann, also know as Whissi for all his good advice and sometimes strong words that drive use towards better quality. While many folks have helped us with this, Whissi is consistenytly insisting on good QA policies for a long time now, and he always was persistent in fighting with me when I did not understand the value or did not want to. Whissi, I admit I sometimes wasn't too fond of you, but believe me, at the end of the day I *really* value what you are doing. You have my deepest respect. Looking forward to many more years of discussions!

simplifying rsyslog JSON generation

With RESTful APIs, like for example ElasticSearch, you need to generate JSON strings. Rsyslog will soon do this in a very easy to use way. ...
