Issue #16221 has been updated by Erik Dalén.
Would the recommended method for creating a resource and passing nothing for some of the values be to use create_resources() and a config hash like in [puppetlabs-mysql/manifests/server.pp](https://github.com/puppetlabs/puppetlabs-mysql/blob/master/manifests/server.pp) lines 28-30? That wouldn't work in the debbuilder example mentioned above though if you only pass a value for cow_root and want to keep the default value for cows. The only decent way to accomplish that without code duplication would be to have both classes inheriting from the same params class and getting the default value from there. However, the current style guideline recommends against doing that (because it requires Puppet 2.6.3+). So if you decide to change the behavior here I think you should change the style guideline as well. ---------------------------------------- Bug #16221: Passing undef as argument to classes & defines overrides default parameter https://projects.puppetlabs.com/issues/16221#change-70949 Author: Erik Dalén Status: Closed 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.
