Bug #4238: an undef variable is not anymore an empty string
http://projects.puppetlabs.com/issues/4238
Author: Peter Meier
Status: Unreviewed
Priority: Normal

Target version:
Affected version: 2.6.0rc3

Branch:
Due to #2818 a lot of people used a workaround that went like that one:
<pre>
case $some_undefined_variable {'': { $some_undefined_variable = 'foo' } }
</pre>
or
<pre>
if $some_undefined_variable == '' { $some_undefined_variable = 'foo' }
</pre>
However an undefined variable in 2.6rc3 doesn't anymore equals to an empty
string which is actually totally fine and the way to go. However, this will
certainly break a lot of existing manifests and when it's not somehow fixed (as
it wasn't by intention) then it should certainly outlined in the release notes,
so people see that they have to adjust their manifests.
Further: Am I right in my assumption that this is only an issue on the master
and I have therefore no problem in mixing 2.6 master with 0.25.5 clients? So if
I fix it for the master it's fixed for all?
