Puppet

From the original report:

I had a typo in my require default line which didn’t raise any sort of error until I added to a specific resource. That is I had $require = Class["apps::postgres::multi"] when there was no such class (the class was named apps::postgresql::multi) and this did not raise an error.

I found the typo when I had an ordering issue and tried adding the require => Class["apps::postgres::multi"] to a specific resource and this generated the error “err: Failed to apply catalog: Could not find dependency Class …”.

It should generate the ‘could not find dependency’ error for the default.

I have verified this: assigning a reference to a type does absolutely not validation in Puppet 2.7, including when the content is consumed in some cases:

$foo = Class["foo"]
$bar = Banana["bar"]  # note: no such type!
notice("hello, $foo, from your little $bar")

Instead, the referenced type and entity should be validated during compilation, so that a clear error occurs when you reference a non-existent anything – not just when that value would be consumed in a way that dereferences the dependency.
