Title: Message Title

Nick Lewis created an issue   Puppet / PUP-6721 Implicit produces/consumes mappings will read variables from topscope Issue Type: Bug Assignee: Unassigned Created: 2016/09/21 3:18 PM Priority: Normal Reporter: Nick Lewis When capabilities are produced or consumed with implicit mappings, parameters are set automatically by name. For instance, the following produces mapping will automatically set host and port on the produced Http resource to the values of $host and $port from the component. This is desirable: define component($host, $port) { }   Component produces Http { } However, the current implementation of this effectively works as if the mapping were explicit for every parameter, and evaluated in the scope of the component, resulting in behavior like: Component produces Http { host => $host, port => $port, path => $path, # etc } That is, if a correspondingly named parameter doesn't exist on the component, it will still be looked up in the enclosing scope. In this case, the path parameter of the produced Http capability, which should ordinarily default to /, will instead be set to /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin. When doing implicit mapping for either produces and consumes statements, only parameters that are actually set on the component or capability (respectively) should be considered, without falling back to topscope. If the mapping sets an explicit _expression_, that _expression_ should still be evaluated as normal, including falling back to topscope, so that mappings like host => $::fqdn still work.
