lookup.rb failing automatic parameter lookup with module data binding

Title: Message Title

PUP-7175

Henrik Lindberg, Thomas Hallgren should APL still work (puppet 5.0) in a module's data function like this:

[root@nvsibssvddx5lxn lookup.9DdSJe]# cat environments/production/modules/data_module/lib/puppet/functions/data_modul

e/data.rb

          Puppet::Functions.create_function(:'data_module::data') do

            def data()

              { 'data_module::module_data_implied' => 'module_implied_b',

                'data_module::module_data' => 'module_b',

                'data_module::hash_name' => {'module_hash_key' => 'module_class_b'},

                'data_module::array_key' => ['module_array_a', 'module_array_b']

end

end

[root@nvsibssvddx5lxn lookup.9DdSJe]# cat environments/production/manifests/site.pp

    site {

      #this should not do anything on the agents as it's compiled into the environment catalog

      # we're just ensuring it compiles, here

      $lookup_port = lookup('apache_server_port')

      notify { "the call to apache_server_port is coming from inside the site clause: $lookup_port": }

      node default {

        include data_module

[root@nvsibssvddx5lxn lookup.9DdSJe]# cat environments/production/modules/data_module/manifests/init.pp

                         $apache_server_port_implied,

                         $automatic_data_key=$automatic_default_value) {

      # lookup data from the environment function databinding

      notify { "apache_server_port_implied $apache_server_port_implied": }

      $lookup_port = lookup("apache_server_port")

      notify { "apache_server_port $lookup_port": }
