Issue #15756 has been updated by Daniel Pittman.
I still get test failures with the updated code:
<pre>
1) The require function should add a dependency between the 'required' class
and our class
Failure/Error: @scope.function_require("requiredclass")
ArgumentError:
custom functions must be called with a single array that contains the
arguments
# ./lib/puppet/parser/functions.rb:65:in `block in newfunction'
# ./spec/integration/parser/functions/require_spec.rb:20:in `block (2
levels) in <top (required)>'
2) The require function should queue relationships between the 'required'
class and our classes
Failure/Error: @scope.function_require("requiredclass1")
ArgumentError:
custom functions must be called with a single array that contains the
arguments
# ./lib/puppet/parser/functions.rb:65:in `block in newfunction'
# ./spec/integration/parser/functions/require_spec.rb:31:in `block (2
levels) in <top (required)>'
3) Puppet::Parser::Functions#hiera_array should raise a useful error when nil
is returned
Failure/Error: expect { scope.function_hiera_array("badkey") }.to

4) Puppet::Parser::Functions#hiera_hash should raise a useful error when nil
is returned

7) Puppet::Parser::Functions when calling newfunction should create the
function in the environment module
Failure/Error: Puppet::Parser::Functions.newfunction("name", :type =>
:rvalue)
Mocha::ExpectationError:
unexpected invocation:
#<Module:0x7f850bcc6c98>.define_method('real_function_name')
unsatisfied expectations:

- allowed any number of times, invoked once:

# ./lib/puppet/parser/functions.rb:58:in `newfunction'
# ./spec/unit/parser/functions_spec.rb:27:in `block (3 levels) in <top
(required)>'
8) Puppet::Parser::Functions when calling newfunction should warn if the
function already exists
Failure/Error: Puppet::Parser::Functions.newfunction("name", :type =>
:rvalue)
Mocha::ExpectationError:
unexpected invocation:

# ./spec/unit/parser/functions_spec.rb:32:in `block (3 levels) in <top
(required)>'
9) Puppet::Parser::Functions when calling function to test function existance
should return its name if the function exists
Failure/Error: Puppet::Parser::Functions.newfunction("name", :type =>
:rvalue)
Mocha::ExpectationError:
unexpected invocation:
#<Module:0x7f850eb85ed0>.define_method('real_function_name')

Bug #15756: scope.function_template with a single String parameter fails in
Ruby 1.9
https://projects.puppetlabs.com/issues/15756#change-70834
Author: Roger Que
Status: In Topic Branch Pending Review
Priority: Normal
Assignee: Andrew Parker
Category: templates
Target version: 3.0.0
Affected Puppet version: 2.7.18
Keywords: ruby19 functions
Branch: https://github.com/puppetlabs/puppet/pull/1105
The Puppet documentation mentions [using `scope.function_template` with a
String
parameter](http://docs.puppetlabs.com/guides/templating.html#access-to-variables-and-puppet-functions-with-the-scope-object)
in order to render an ERB template inside another template:
<%= scope.function_template('referenced_template.erb') %>
This works in Ruby 1.8, but fails with the following error when the Puppet
master is running 1.9:
err: Could not retrieve catalog from remote server: Error 400 on SERVER:
Failed to parse template [xxx].erb:
Filepath: /usr/share/ruby/vendor_ruby/puppet/parser/functions/template.rb
Line: 10
Detail: undefined method `collect' for "referenced_template.erb":String
at /etc/puppet/modules/[yyy].pp:164 on node [zzz.example]
It looks like the `template` function is invoking `collect` on its argument
regardless of whether it's a String or Array, which works in Ruby 1.8
(`'abc'.collect` behaves like `['abc'].collect`) but not in 1.9. Passing an
Array works with both versions.
This is on Fedora 17, Ruby 1.9.3p194, with Puppet 2.7.18.
