[Puppet - Bug #22800] dynamic variable lookup works in templates
Issue #22800 has been updated by David Portabella.
I have the same issue.
according to http://docs.puppetlabs.com/guides/scope_and_puppet.html
about dynamic lookup from an included puppet file:
puppet 2.7 warns about it, and puppet 3.2 stops working, as expected.
however,
about dynamic lookup from a template called on an included puppet file:
both puppet 2.7 and puppet 3.2 it works, without even a warning. (see in red
the below example)
Why is that?
dynamic lookup in templates should show a warning in puppet 2.7, and stop
working on puppet 3.
See below a specific example:
test.pp
class c1 {
$var = 'hello'
notify {var from c1: $var: }
include c2
}
class c2 {
notify {var from c2: $var: }
file { '/tmp/file.txt':
content = template('file.txt.erb'),
}
}
class { c1: }
file.txt.erb
var from file.txt.erb: %= @var %
running with puppet 2.7.19:
$ puppet apply --templatedir templates/ test.pp
warning: Dynamic lookup of $var at /vagrant/t1/test.pp:8 is deprecated. For
more information, see http://docs.puppetlabs.com/guides/scope_and_puppet.html.
To see the change in behavior, use the --debug flag.

Bug #22800: dynamic variable lookup works in templates

* Author: Robert Birnie
* Status: Unreviewed
* Priority: Normal
* Assignee:
* Category: templates
* Target version:
* Affected Puppet version: 3.2.2
* Keywords: templates scope
* Branch:
Summary:
From within templates, dynamic lookup of variables seems to work. I can
declare a variable in the init.pp file. It shows up as undefined in the
configuration.pp file. But then it will work fine within the templates created
by configuration.pp.
Steps to Reproduce:
I've created a github repo with a simple module that shows off the issue.
Basically its just creating a dynamic lookup variable in a template though,
nothing special.
https://github.com/rbirnie/puppet_scope_bug
Expected Results:
The variable should return undef which is what the manifests return.
Actual Results:
The variable returns the value that is assigned.
Notes:
Both agent and master are puppet 3.2.2
