Bug #3490: Defined() requires the class to exist when used in an if statement
http://projects.puppetlabs.com/issues/3490
Author: Ashley Penney
Status: Unreviewed
Priority: Low

Affected version: 0.25.4
Keywords: defined function
Branch:
This may not be a bug, but it should be documented perhaps as it was surprising
to me. While doing some testing if a new module I pushed the following snippet
to my production modules:
if defined(Class["splunk4::client"]) {
stuff here
}
This then failed when nodes checked in with:
err: Could not retrieve catalog from remote server: Error 400 on SERVER: Could
not find class splunk4::client at
/etc/puppet/modules/production/rhythmyx/manifests/init.pp:20 on node
hlstestper1.law.harvard.edu
because the splunk4 module wasn't in production. Simply moving it into the
production environment (and including it nowhere) was enough to get it working
which was unexpected. I would expect in an if statment that it would simply
ignore any errors from defined and skip the block, not crash and burn.
