Bug #3382: Class require chain thru class with no resources
http://projects.reductivelabs.com/issues/3382

Author: Alan Harder
Status: Unreviewed
Priority: Normal
Assigned to: 
Category: functions
Target version: 
Affected version: 0.25.4
Keywords: require
Branch: 


This may be working as designed, but wanted to file an issue to make sure.
Consider this test case:
<pre>
class foo {
  notify { 'foo': }
  class bar {
    require foo
#    notify { 'bar': }
  }
}
class baz {
  require foo::bar
  notify { 'baz': }
}

node default {
  include baz
}
</pre>

When notify 'bar' is uncommented, this works as expected.. the notify messages 
always appear in order: foo, bar, baz.  However, with notify 'bar' commented 
the order is sometimes foo,baz and sometimes baz,foo.  It seems that some 
resource must be in the foo::bar class to enforce that foo is evaluated before 
baz.  Is this expected that a class level "require" chain only works when each 
link in the chain has at least one resource?  I use a setup like this sometimes 
where a subclass sets some variables and then requires the outer class, so it 
has no resources of its own.  If you have another recommended way to do this, 
let me know :-)  I guess I could do "require foo::bar, foo" but that's less 
intuitive usage.  Thanks.
