Bug #18234: Booleans used from within hashes not working correctly.
https://projects.puppetlabs.com/issues/18234

Author: Andrew Hendry
Status: Unreviewed
Priority: Normal
Assignee: 
Category: 
Target version: 
Affected Puppet version: 
Keywords: puppet hashes booleans defaults
Branch: 



booleans_from_hashes.pp

<pre>$puppet_hash = {
  hflag1 => true,
  hflag2 => false
}

notice("hflag1 should be true  = '${puppet_hash[hflag1]}'")
notice("hflag2 should be false = '${puppet_hash[hflag2]}'")

dummy {'fromhash':
 flag1 => $puppet_hash[hflag1],
 flag2 => $puppet_hash[hflag2]
}

dummy {'assigned':
 flag1 => true,
 flag2 => false
}

define dummy
(
  $flag1 = true,
  $flag2 = true,
) {

  notice("${name} flag1 should be true  = '${flag1}'")
  notice("${name} flag2 should be false = '${flag2}'")
}
</pre>

Output:
<pre>
puppet apply booleans_from_hashes.pp
notice: Scope(Class[main]): hflag1 should be true  = 'true'
notice: Scope(Class[main]): hflag2 should be false = ''
notice: Scope(Dummy[fromhash]): fromhash flag1 should be true  = 'true'
notice: Scope(Dummy[fromhash]): fromhash flag2 should be false = 'true'
notice: Scope(Dummy[assigned]): assigned flag1 should be true  = 'true'
notice: Scope(Dummy[assigned]): assigned flag2 should be false = 'false'
notice: Finished catalog run in 0.04 seconds
</pre>

<pre>
puppet --version
2.7.14
ruby --version
ruby 1.8.7 (2010-06-23 patchlevel 299) [x86_64-linux]
</pre>

flag2 should be false when pulled from the hash but it appears to be empty, 
resulting in the default being used.
This does not happen when passing booleans directly.

Does anyone know a workaround or fix?
