Overview

TODO: simplify if tickets.puppetlabs.com/browse/PUP-1159 gets fixed. Override the default caching logic created in Puppet.features:

meta_def(‘cisco_node_utils?’) do

# we return a cached result if:
#  * if a block is given (and we just evaluated it above)
#  * if we already have a positive result
#  * if we've tested this feature before and it failed, but we're
#    configured to always cache
if block_given? ||
   @results['cisco_node_utils'] ||
   (@results.has_key?('cisco_node_utils') and
    Puppet[:always_cache_features])
  @results['cisco_node_utils']
else
  @results['cisco_node_utils'] = test('cisco_node_utils',
                                      libs: ['cisco_node_utils'])
  @results['cisco_node_utils']
end
