Bug #1243: puppet thinks yum fails to update a package when it succeeds
http://reductivelabs.com/redmine/issues/show/1243

Author: robfay
Status: Closed
Priority: Normal
Assigned to: jamtur01
Category: package
Target version: 0.24.5
Keywords: 
Complexity: Easy
Patch: None
Affected version: 


When trying to use puppet to update a package to a particular version and exec
a command when that update is applied, puppet calls yum which successfully 
updates the package, but puppet then thinks the update has failed and hence 
doesn't trigger the exec. Next cycle the package is already the correct 
version, so the update isn't applied, so the exec is never called.

manifest snippet:
<pre>
     package { "test":
         ensure => "1.21",
     }

     exec { "testcmd":
         command => "/foo/bar",
         refreshonly => true,
         subscribe => package[[test]]
     }
</pre>
Output from puppetd:

err: /:main/Node[testnode]/test/Package[test]/ensure: change from 1.20 to 1.21 
failed:
Could not update: Failed to update to version1.21, got version 1.20 instead at
/etc/puppet/modules/test/manifests/init.pp:28
notice: /:main/Node[testnode]/test/Exec[testcmd]: Dependency package[test] has 
1 failures
warning: /:main/Node[testnode]/test/Exec[testcmd]: Skipping because of failed 
dependencies

The package is successfully updated to 1.21. The yum command -
'/usr/bin/yum -d 0 -e 0 -y install test-1.21' - works fine with returncode
0 and no errors when run independently. 

O/S is Scientific Linux 4 (RHEL4), yum version is 2.4.2.

Response from Luke on puppet-users:

"This is a result of the following code:
<pre>
         is = self.query
         unless is
             raise Puppet::Error, "Could not find package %s" % self.name
         end

         # FIXME: Should we raise an exception even if should == :latest
         # and yum updated us to a version other than @param_hash[:ensure] ?
         if should && should != is[:ensure]
             raise Puppet::Error, "Failed to update to version  
#{should}, got version #{is[:ensure]} instead"
         end
</pre>
I *think* that code is in place because yum always exits 0, so we need  
to do extra checking to see if it actually installed or not.

It looks like the query isn't actually running again, which is your  
problem.

Please file this as a bug; it should be relatively straightforward to  
fix."
