Augeas with puppet 3.4.2

[Ryan Anderson]

I have some augeas code that works flawlessly with puppet 2.6.17, but when running the identical code on 3.4.2, I get an error.

The code:

   augeas { 'myuser_in_logingroup':

      context     => '/files/etc/group',

      changes     => [ "set ${hostname}/user[last()+1] myuser", ],

      onlyif      => "match ${hostname}/*[.='myuser'] size == 0",

      require     => Group['local_login_group'],

    }

The error from running 'puppet agent -tv':

Warning: Augeas[myuser_in_logingroup](provider=augeas): Loading failed for one or more files, see debug for /augeas//error output

Error: /Stage[main]/Group_management/Augeas[myuser_in_logingroup]: Could not evaluate: Save failed with return code false, see debug

I'm having a difficult time finding/understanding clues from debug output. Any ideas?

[Rob Reynolds]

Ryan, would you mind running 'puppet agent --trace --verbose --debug' and posting the output here?

Cool. Does this mean I need to update augeas.rb from github.com or wait for it to make it into a future release? What should I do to fix it now?

In case it helps, here are the problem bits from the debug output:

The fix that Marcelo pointed out isn't relevant here, it's to fix a
false positive log message. The log message is actually correct in this
instance, no need to update augeas.rb.

The Augeas library is unable to parse something on line 51 of your
/etc/group file. From the debug: augeas/files/etc/group/error/line = 51

Look to see what's there and maybe you can edit the file to workaround
the problem. If the file is still valid, then please file a bug either
with your distribution or upstream
(https://github.com/hercules-team/augeas/issues).

Excellent catch, the error was indeed an improperly-formatted /etc/group entry (on line 51). Thanks for your help! I've learned a lot about augeas through this.

The old adage applies: garbage in, garbage out.
