Subject: configfile.c: Ignore registered undefined config keys.
X-Git-Tag: collectd-4.5.2~7
X-Git-Url: https://git.verplant.org/?a=commitdiff_plain;h=de4c4c1a394b70a392aeb85ae770f2381771a428;p=collectd.git

configfile.c: Ignore registered undefined config keys.

If a registered config key equals NULL, it is now ignored. Before, this would
cause a segfault. As this has happened a few times in the past, we not handle
it sanely.
