---------------------------------------- Bug #14677: Puppet 3.0.x variable assigned to undef returns :undef in template https://projects.puppetlabs.com/issues/14677#change-64385 Author: Jeff McCune Status: Accepted Priority: Normal Assignee: Category: parser Target version: 3.x Affected Puppet version: Keywords: scope lookupvar template undef undefined nil Branch: # Overview # We've made good progress returning nil values in ERB templates in 3.0.x but we're not out of the wood yet. A fairly common pattern is to assign undef to a variable in the Puppet DSL, meaning "Treat this variable as undefined." The expected behavior is that the variable behaves as if it were not defined. The following manifest should illustrate the problem. The expected behavior is that we receive nil. <pre> $undefined = undef $foo = inline_template("<% require 'pry'; binding.pry; vapid_var; %>") </pre> <pre> [7] pry(#<Puppet::Parser::TemplateWrapper>)> scope.lookupvar('undefined_no_really') => nil [8] pry(#<Puppet::Parser::TemplateWrapper>)> scope.lookupvar('undefined') => :undef </pre> -- You have received this notification because you have either subscribed to it, or are involved in it.
