2012-08-15Explicitly load functions used by ensure_resourceDan Bode
The ensure_resource function actually calls two other functions, create_resources and defined_with_param. When calling Puppet functions from Ruby, you sometimes have to load the functions manually if they have not been called before. This commit explicitly loads the functions that ensure_resource depends on from within the function.

2012-08-13Add better docs about duplicate resource failuresDan Bode
This commit adds better inline documentation explaining how replicate resource definitions can occur if the resource exists and does not have matching parameters.
2012-08-13Add function ensure_resource and defined_with_paramsDan Bode
This commit adds 2 new functions with unit tests. defined_with_params works similarily to puppet's defined function, except it allows you to also specify a hash of params. defined_with_params will return true if a resource also exists that matches the specified type/title (just like with defined) as well as all of the specified params. ensure_resource is a function that basically combines defined_with_params with create_resources to conditionally create resources only if the specified resource (title, type, params) does not already exist. These functions are created to serve as an alternative to using defined as follows: if ! defined(Package['some_package']) { package { 'some_package': ensure => present, } The issue with this usage is that there is no guarentee about what parameters were set in the previous definition of the package that made its way into the catalog. ensure_resource could be used instead, as: ensure_resource('package', 'some_package', { 'ensure' => 'present' }) This will creat the package resources only if another resource does not exist with the specified parameters.
