Issue #16221 has been updated by eric sorenson.
Haus has a good real-world example of this: https://github.com/puppetlabs/puppetlabs-debbuilder/blob/master/manifests/init.pp Previously, the behaviour would have been like leaving `$cows` off the debbuilder::setup::cows invocation on line 18. Now, we pass the `undef` through, overriding the default in the called class with it. ---------------------------------------- Bug #16221: Passing undef as argument to classes & defines overrides default parameter https://projects.puppetlabs.com/issues/16221#change-70528 Author: Erik Dalén Status: Investigating Priority: Normal Assignee: eric sorenson Category: Target version: 3.0.0 Affected Puppet version: 3.0.0-rc5 Keywords: parameter undef Branch: In puppet 3.0.0-rc5 the default value is overridden if I pass undef as a parameter to a define or class. Example: define bar ($param='Hello world') { notice($param) } define foo ($param=undef) { bar { 'bartest': param => $param } } foo { 'footest': } In puppet 2.7.19 that outputs: notice: Scope(Bar[bartest]): Hello world But in puppet 3.0.0-rc5 I get: Scope(Bar[test]): -- You have received this notification because you have either subscribed to it, or are involved in it.
