From 65ef24e5c1c33b7d42012891d368917fd6aaf68c Mon Sep 17 00:00:00 2001 From: Paul Berry Date: Fri, 8 Oct 2010 15:26:28 -0700 Subject: (#4534/#4778) -- Normalize parameterized classes This is a reconciliation/melding of Paul's (#4534) Class inheritance with parameterized classes is no longer ignored and Markus's Fix for #4778 -- evaluate parameterized classes when they are instantiated Extracted the code from Resource::Type#mk_plain_resource that evaluates parents and tags the catalog, and moved that into a new method called instantiate_resource. Instantiate_resource is now also called from Parser::Ast::Resource#evaluate, so that the notation "class { classname: }" now executes this code too. Likewise adds class evaluation so that it behaves the same (with regard to lazy / strict evaluation) as include classname --- lib/puppet/resource/type.rb | 31 ++++++++++++++++++------------- 1 file changed, 18 insertions(+), 13 deletions(-) (limited to 'lib/puppet/resource') diff --git a/lib/puppet/resource/type.rb b/lib/puppet/resource/type.rb index 7b21e55dc..d40adc145 100644 --- a/lib/puppet/resource/type.rb +++ b/lib/puppet/resource/type.rb @@ -138,21 +138,15 @@ class Puppet::Resource::Type end end - # Make an instance of our resource type.
