Issue #21948 has been updated by Charlie Sharpsteen. Description updated Category set to language Assignee set to eric sorenson
Agreed that this is currently behaving as intended. It seems that you are looking for is a way to test if the intersection of two sets is empty. In Ruby: <pre> (ary1 & ary2).empty? </pre> It appears that `==` in Puppet already covers not only equality but, surprisingly, [inclusion](https://github.com/puppetlabs/puppet/blob/3.2.4/lib/puppet/parser/ast/collexpr.rb#L37-L41). I would be wary of further extending `==` to cover intersection as this operator strictly covers equality in most programming languages. Each departure from this norm could surprise users who are expecting an equality test but end up with a test for intersection or even inclusion. Eric, any thoughts on this one? ---------------------------------------- Feature #21948: resource collection == doesn't compare arrays vs arrays https://projects.puppetlabs.com/issues/21948#change-98434 * Author: Jeremy Kitchen * Status: Needs Decision * Priority: Normal * Assignee: eric sorenson * Category: language * Target version: * Affected Puppet version: * Keywords: * Branch: ---------------------------------------- given: <pre> @user { 'foo': groups => ['a','b'], } @user { 'bar': groups => ['b','c'], } </pre> This is what DOES happen: <pre> User<| groups == ['a', 'b'] |> # realizes only user foo User<| groups == 'b' |> # realizes both, as to be expected </pre> So, it would appear that an array on the left hand side is acceptable, but not on the right. This is what I would expect: <pre> User<| groups == ['a','b'] |> # realizes both User<| groups == ['a', 'c'] |> # realizes both </pre> I mainly want this so I can do: </pre> User<| groups == hiera_array('include_groups') |> </pre> I'm using puppet 3.2.3 on both master and agent. I'm not against doing something like: <pre> $include_groups = hiera_array('include_groups') $include_groups.each { | $group | User<| groups == $group |> } </pre> The only problem I have with that is it's experimental and may go away, so I don't want to rely upon that functionality if it may not be there next version. The documentation says it will pull in all resources matching the search key (the right hand operand), which I admittedly initially misread, but the fact that *anything* gets returned makes me wonder if there's more behind this issue. -- You have received this notification because you have either subscribed to it, or are involved in it.
