Puppet

When puppet encounters a malformed host type, say because the variable for the ip address is unassigned, it produces a hard to debug error messages. Using lucid, and the puppet packaged for it:

root@dell-r610-4v0hsl1:~# cat /tmp/host.pp 
host{ "test":
   ip => "",
 }

 root@dell-r610-4v0hsl1:~# puppet --version
 0.25.4

 root@dell-r610-4v0hsl1:~# puppet -v /tmp/host.pp 
 info: Loading facts in acpi_available
 info: Loading facts in interfaces
 Parameter ip failed: Invalid IP address

I’d really like to see the name of the offending file, and the line. And something me it was a host type.

This bug feels pretty much identical to #2633 (which I created awhile ago). Which makes me think there’s a meta issue around error messages, and not just these ad hoc bugs. Judging from the diff in #2633, this ends up being related to raising errors, and not calling self.fail? But I’m kinda grasping at straws. I suspect someone with more ruby and puppet internals knowledge could grep for cases of this.
