Title: Message Title

Ryan Struber created an issue   Hiera / HI-595 Knock-out-prefix fails with more than 3 merges Issue Type: Task Assignee: Unassigned Created: 2018/01/30 8:59 AM Priority: Normal Reporter: Ryan Struber When defining multiple levels of hierarchy in hiera.yaml (more than 3), and requesting hiera to lookup a key that is found on more than 3 levels, and lookup options for that key are configured to merge deep with a knockout prefix, the merge fails to knockout the key matching the higher precedence knockout. Steps to reproduce: hiera.yaml: version: 5 defaults: datadir: data data_hash: yaml_data   hierarchy: - name: node specific data path: node/%{::site.node}.yaml   - name: product data path: product/%{::site.product}.yaml   - name: os data path: os/%{::os.family}.yaml   - name: global data path: common.yaml common.yaml: lookup_options: classes: merge: strategy: deep knockout_prefix: "--" classes: - profiles::motd - profiles::network   os/RedHat.yaml: classes: - profiles::yum   product/product.yaml classes: - profiles::application   node/node.yaml: classes: - profiles::puppet-agent - "--profiles::network" - network Expected puppet lookup --knock-out-prefix '--' --merge deep classes --- - profiles::motd - profiles::yum - profiles::application - network Actual puppet lookup --knock-out-prefix '--' --merge deep classes --- - profiles::motd - profiles::network - profiles::yum - profiles::application Removing a layer from the hierarchy causes the merge to behave as expected. The difference being: puppet lookup --knock-out-prefix '--' --merge deep classes | grep 'Found key:' | wc -l 4 vs puppet lookup --knock-out-prefix '--' --merge deep classes | grep 'Found key:' | wc -l 3 Add Comment   This message was sent by Atlassian JIRA (v7.0.2#70111-sha1:88534db) -- You received this message because you are subscribed to the Google Groups "Puppet Bugs" group.
