 Description   

Puppet6 will error if a module contains an empty init.pp. The module documentation says, "init.pp: Contains a class definition. The init.pp class, if used, is the main class of the module. This class's name must match the module's name."

So the init.pp file is optional, but we don't specify whether the file can exist, but be empty or if it only contains a defined type.

We discovered in MODULES-7854 that some people may have empty init.pp and puppet should be more lenient. For now, we removed the empty init.pp from the rspec-puppet's module fixtures.

Uh oh, that sounds as a bug in the checker - if it is empty it should not find a class in that file and should have nothing at all to verify, seems like it goes off the road with a strange error message.

Should any file be allowed to be empty, or just the special init.pp?  /cc Henrik Lindberg, Josh Cooper, Charlie Sharpsteen, Ben Ford

Allowing any .pp file to be empty seems less complicated all around to me.

Comment by Henrik Lindberg [ 2018/10/09 ]

Well, some files cannot really be empty, but those are checked by the loaders (functions and data types in .pp files for example). Validation should just accept "empty" files ("empty" here meaning no resulting AST as there could example be comments etc. so file may not be exactly void of content to be considered empty).
