Bug #9848: Variable interpolation in class parameters seems random
https://projects.puppetlabs.com/issues/9848
Author: Carlos Sanchez
Status: Unreviewed
Priority: Normal
Assignee:
Category: parameterized classes
Target version:
Affected Puppet version: 2.7.1
Keywords: parameter variable class interpolation evaluation
Branch:
In class parameters, things like x="x", y="y${x}" don't always evaluate right
(y="yx"), seems random. I'm using 2.7.1
<pre>
class test1(
$servicex = "sonar",
$logfoldera = "${homex}/logs",
$logfoldere = "${homey}/logs",
$logfolderh = "${homez}/logs",
$logfolder = "${homex}/logs",
$homex = "/var/${servicex}",
$homey = "/var/${servicex}",
$homez = "/var/${servicex}") {
notice($homex)
notice($homey)
notice($homez)
notice("-----")
notice($logfoldera)
notice($logfoldere)
notice($logfolderh)
}
</pre>
output :
<pre>
notice: Scope(Class[Test1]): /var/sonar
notice: Scope(Class[Test1]): /var/sonar
notice: Scope(Class[Test1]): /var/sonar
notice: Scope(Class[Test1]): -----
notice: Scope(Class[Test1]): /var/sonar/logs
notice: Scope(Class[Test1]): /logs
notice: Scope(Class[Test1]): /logs
</pre>
Note the last two messages should print "/var/sonar/logs"
Ordering the paramenters in the order they are needed gets the same result.
Just by changing the name of the parameters from class test1 to test2 I get
different evaluations of the variables, one is right and two are wrong, you can
see that in [this gist](https://gist.github.com/1250837)
