Puppet

The ‘!=’ comparator in the Augeas resource type (specifically with onlyif match size) does not work properly in puppet due to the underlying Ruby interpreter not supporting ‘!=’ with send. Here is thread discussing the ruby issue: http://www.ruby-forum.com/topic/174382. The thread seems to indicate that Ruby versions greater than 1.9 support it ‘!=’ with send but I have not tested this.

I am using puppet 2.6.2 with ruby 1.8.5 on CentOS 5.5.

Puppet code that illustrates the problem:

augeas {
  "grub":
    context => "/files/etc/grub.conf",
    onlyif => "match timeout[.='30'] size != 1",
    changes => [
      "rm timeout",
      "ins timeout before title[1]",
      "set timeout 30",
    ],
}

With the code snippet above, puppet will execute the augeas statements on every run despite “timeout 30” line being present in the grub.conf file.

Attached is a patch against puppet 2.6.2.

I also notice there are no debug() statements in process_match(). Might be useful to have a couple statements in there to at least indicate that the onlyif/match statement is being processed.

I think this issue should be fixed sooner than later because it makes it that much harder and frustrating to debug the augeas resource type when the underlying implementation does not work.
