In case if it actually is necessary in practice, we need to find
out why, because the property should never be NULL. If this somehow
happens, we need to fix that or find at least a better spot for a
fix.
Older versions of json-c need to use a different API (which don't exists
on newer versions, unfortunately...)
Thanks to Thomas D. for reporting this problem.
This should be the correct version of this commit:
commit 6138ced6ce4abbaccf4c45f7b69a14811feb96ad
imuxsock: don't report an error message for $OmitLocalLogging
And in effect reverts this commit:
commit d77a8b1b8877d2dd1a0248b07564d1f88be00deb
imuxsock: When syssock.use set to off, additional listeners cannot be created
The system socket parameters were initialized twice and most of the
values set at first were overwritten. All the assignments are now
moved to activateListeners(). The parameters aren't accessed before
then.
Hash table and rate limiter for the system socket weren't freed.
A side-effect was that the "Last message repeated..." notice didn't
get printed if rsyslog was shut down before the repetition was broken.
The hash table for the system socket was allocated twice. The other
one being in activateListeners().
This commit practically reverts: 34a77cde2423303da72ab773128a2ddcf41
The issue seems to be that the hash table is not initialized (to NULL)
rather then not being allocated.
