Jira (PUP-5959) Derive static catalog metadata lookup defaults from File type

[William Hopper (JIRA)]

Title: Message Title

William Hopper commented on PUP-5959   Re: Derive static catalog metadata lookup defaults from File type Michael Smith poking at this, I found that to figure out what `defaulto` is set to for each parameter would require us to instantiate a new instance of each parameter meta-class with a resource as an argument, i.e: pry(#<Puppet::Resource::Catalog::Compiler>)> Puppet::Type::File::ParameterLinks.default => nil   pry(#<Puppet::Resource::Catalog::Compiler>)> thing = Puppet::Type::File::ParameterLinks.new(:resource => resource) ameterLinks.new(:resource => resource)   pry(#<Puppet::Resource::Catalog::Compiler>)> thing.default thing.default => :manage This is because of the way the metaprogramming of define_method(:default) in Puppet::Type works. It's a weird, fuzzy process that I still don't fully understand, but we end up creating a newattr which enables the default method of the klass to return our default. This may be due to the fact that a parameter can have its default set to a block instead of a symbol. def set_default(attr) ... return unless parameter = newattr(klass.name) # parameter (i.e, "ParameterLinks", "ParameterSource_Permissions") can now be queried for its default value ... end This is all terrible anyway, as we don't even technically know anything about those meta-programmed parameter classes (like their names). The only other thing I can think of is to create a dummy File resource with nothing but a name and check its defaults: pry(#<Puppet::Application::Apply>)> defaults_resource = Puppet::Type.type(:file).new(:name => '/defaults')   pry(#<Puppet::Application::Apply>)> defaults_resource[:links] => :manage   pry(#<Puppet::Application::Apply>)> defaults_resource[:source_permissions] => :ignore Any thoughts? This stuff is pretty wild Add Comment   This message was sent by Atlassian JIRA (v6.4.12#64027-sha1:e3691cc) -- You received this message because you are subscribed to the Google Groups "Puppet Bugs" group.
