libfastjson returns NULL for json "null" objects, and callers need to handle this. This is correctly handled in almost all code path in rsyslog, and this patch fixes theoretical issues in the remaining two places. Note, however, that a json null object can not really occur at those places due to the rest of processing. But we wanted to include the check anyways. closes https://github.com/rsyslog/rsyslog/issues/600
This directory contains a number of possibly useful things that do not directly relate to rsyslog. They are not actively supported, but as I said often helpful. Use them with some care, as they may be outdated in respect to the current release of rsyslog. At least some of this stuff has been found by our users and been included after a brief check and possibly an adapation. If you have something useful you would like to see in contrib, just drop us a note (see http://www.rsyslog.com for how to do that at the time your are reading this document). rgerhards, 2007-08-08
