I believe how we cast things to strings in functions, particularly undef values, is a major contributor to this perception. This is absolutely not something we should change in a minor release and ideally we'll have a full major release where we give a deprecation warning with clear steps to take for authors of functions and types. ---------------------------------------- Bug #13210: undef changes into '' when passed to function as a param https://projects.puppetlabs.com/issues/13210#change-59042 Author: Timur Batyrshin Status: Needs Decision Priority: Normal Assignee: Chris Price Category: Target version: Affected Puppet version: Keywords: Branch: Suppose we have a manifest like that: <pre> define foo ( $x = '1' ) { notify { "x${x}": } } class bar { $x = myfunc( undef ) foo {'no1': x=> $x } } class baz { $x = undef foo {'no2': x=> $x } } include bar include baz </pre> With myfunc() defined like that: <pre> module Puppet::Parser::Functions newfunction(:myfunc, :type => :rvalue) do |param| return param end end </pre> When applying the manifest we get the following output. <pre> notice: x notice: /Stage[main]/Bar/Foo[no1]/Notify[x]/message: defined 'message' as 'x' notice: x1 notice: /Stage[main]/Baz/Foo[no2]/Notify[x1]/message: defined 'message' as 'x1' notice: Finished catalog run in 0.06 seconds </pre> However the same message should be produced in both calls to foo. -- You have received this notification because you have either subscribed to it, or are involved in it.
