Issue #20923 has been updated by Andrew Parker.
To throw a wrench in all of this discussion, here is another approach (one that Erik and I had hacked on a little bit at FOSDEM). Create a new way of defining functions that provides the calling semantics that people seem to want to see: * puppet `undef` is passed through as ruby `nil` * puppet numbers are passed through as ruby numbers * functions can declare real, named arguments (no more arguments array) * functions can return valid puppet data (hashes, arrays, strings, numbers) and nil is converted back into puppet undef This would have the advantage of not requiring several more flags for controlling functions. The opt-in to the new behavior is done by simply converting the function to the new interface. ---------------------------------------- Bug #20923: Hiera cannot take `undef` as a default value https://projects.puppetlabs.com/issues/20923#change-91760 * Author: Raphaël Pinson * Status: In Topic Branch Pending Review * Priority: Normal * Assignee: * Category: * Target version: * Affected Puppet version: * Keywords: * Branch: https://github.com/puppetlabs/puppet/pull/1670 ---------------------------------------- As discussed with Jeff McCune yesterday, I believe #13210 is not a duplicate of #15329, as #13210 can be fixed without fixing #15329 per se. Here's the idea: * Implement a new `:honor_undef` option for functions, defaulting to `false`; * Implement a new `:hiera_munge_undef` option in puppet.conf, defaulting to `true` for backwards compatibility; * Use `:honor_undef = true` in all hiera functions when `:hiera_munge_undef` is set to `false`.
