Issue #17715 has been updated by Jon Topper.
The implications of this are that users making use of data bindings will find that it is not possible to reliably set defaults for parameters in a parameterised class outside of the binding itself. Whilst I can live with this, it should probably be elaborated upon in the documentation. ---------------------------------------- Bug #17715: Variables with defaults incorrectly looked up in hiera if a value is not passed to a class declared like a resource. https://projects.puppetlabs.com/issues/17715#change-83167 Author: Jon Topper Status: Closed Priority: Normal Assignee: Category: Target version: Affected Puppet version: 3.0.1 Keywords: Branch: Given a puppet manifest like: <pre> class test_class ( $test_param = 'foo' ) { info( $test_param ) } node default { class { test_class: } } </pre> and a hiera.yaml like <pre> --- :backends: - yaml - puppet :logger: console :hierarchy: - environments/%{fqdn} - common :yaml: :datadir: /tmp :puppet: :datasource: data </pre> When invoked thus: <pre> puppet apply --verbose test.pp --hiera_config ./hiera.yaml </pre> the following warnings occur: <pre> Warning: Scope(Class[Test_class]): Could not look up qualified variable 'data::environments/core.vagrant::test_class::test_param'; class data::environments/core.vagrant::test_class could not be found Warning: Scope(Class[Test_class]): Could not look up qualified variable 'data::common::test_class::test_param'; class data::common::test_class could not be found Warning: Scope(Class[Test_class]): Could not look up qualified variable 'fake::data::test_class::test_param'; class fake::data::test_class could not be found </pre> It looks like this is the hiera code attempting to look up the value of test_param in the hiera data. I believe this is incorrect, and that the behaviour should be equivalent to me invoking the class as <pre> class { test_class: test_param => 'foo' } </pre> which doesn't throw the warnings. TL;DR: if I set a variable's default in the class definition, this shouldn't be looked up in hiera if I don't pass it when declaring the class like a resource. -- You have received this notification because you have either subscribed to it, or are involved in it.
