Title: Message Title

Gary Larizza created an issue   Puppet / PUP-10727 Cannot define a default Timespan value for an attribute in a Ruby language data type Issue Type: Bug Affects Versions: PUP 6.14.0 Assignee: Unassigned Components: Type System Created: 2020/10/23 1:57 PM Labels: typesystem Priority: Normal Reporter: Gary Larizza Puppet Version:  Demonstrated on 6.14.0 Puppet Server Version: N/A - validated locally OS Name/Version: Tested with both CentOS 7 and MacOS 10.15.7 Given the following implementation of a Ruby language data type located at moduleroot/lib/puppet/datatypes/schedule.rb: Puppet::DataTypes.create_type('Mytype::Schedule') do   interface <<-PUPPET     attributes => {       "name"   => Mytype::Name,       "soak_time"       => {         type  => Timespan,         value => Timespan('hours' => 3),       },       "start_time"      => Timestamp,     }   PUPPET   My intent was to provide a default value for the soak_time attribute so that if a value isn't provided then we would default to a Timespan of 3 hours. When I declare an instance of this type without a soak_time value, I get the following error: Evaluation Error: Error while evaluating a Type-Name, The _expression_ <Timespan('hours' => 3)> is not a valid type specification.   I thought that perhaps I was declaring that object incorrectly, so I tried to following declarations for the right side of the 'value' key in the code above and received the following errors:   Timespan('0-03:00:00') Evaluation Error: Error while evaluating a Type-Name, The _expression_ <Timespan('0-03:00:00')> is not a valid type specification.   Timespan.new('0-03:00:00') Evaluation Error: Error while evaluating a Type-Name, The _expression_ <Timespan.new('03:00:00')> is not a valid type specification.   '0-03:00:00' Evaluation Error: Error while evaluating a Type-Name, attribute Mytype::Schedule[soak_time] value has wrong type, expects a Timespan value, got String   Timespan['0-03:00:00'] Error while evaluating a Type-Name, attribute Mytype::Schedule[soak_time] value has wrong type, expects a Timespan value, got Type[Timespan]   Puppet::Pops::Time::Timespan.parse('0-03:00:00') Error while evaluating a Type-Name, The _expression_ <Puppet::Pops::Time::Timespan.parse('0-03:00:00')> is not a valid type specification.   At this point I tried to be clever and instantiate a variable holding a Timespan object, and then pass that in to the interface HEREDOC string: Puppet::DataTypes.create_type('Mytype::Schedule') do   @timespan = Puppet::Pops::Time::Timespan.parse('0-03:00:00')   interface <<-PUPPET     attributes => {       "name"   => Mytype::Name,       "soak_time"       => {         type  => Timespan,         value => @timespan,       },       "start_time"      => Timestamp,     }   PUPPET     load_file 'puppet_x/Mytype/schedule'     implementation_class PuppetX::Mytype::Schedule end   **That gets you this DIFFERENT error: Evaluation Error: Error while evaluating a Type-Name, Data Type Load Error for type 'Mytype::Schedule': can't modify frozen #<Class:#<Puppet::DataTypes::TypeBuilderAPI:0x00007fedbc9bfdf0>   Desired Behavior: A default value for the data type that contains a Timespan object Actual Behavior: So many errors....     For fun you can view the Slack conversation I had with Henrik Lindberg at this link: https://puppetcommunity.slack.com/archives/C0W1X7ZAL/p1603473374140600   Add Comment   This message was sent by Atlassian Jira (v8.5.2#805002-sha1:a66f935) -- You received this message because you are subscribed to the Google Groups "Puppet Bugs" group.
