If package_name can be nil (not sure that's possible?), then it'd be good to set a default:

Suggested change
package_name = @resource.catalog.resource('class', 'puppet_agent')[:package_name]
package_name = @resource.catalog.resource('class', 'puppet_agent')[:package_name] || 'puppet-agent'

I don't think it can (realistically) be nil - but having a sane default still seems like a good idea.


# Latest version might be undefined, e.G. if we're about to install a different named
# package than the currently running one. In that case, we'll leave desired_version empty.
latest_version = @resource.catalog.resource('package', package_name).parameters[:ensure].latest
desired_version = latest_version.match(%r{^(?:[0-9]:)?(\d+\.\d+(\.\d+)?(?:\.\d+))?}).captures.first unless latest_version.nil?

If latest_version is nil, then desired_version will be too, and the versioncmp function will raise:

❯ bundle exec ruby -rpuppet -e 'Puppet::Util::Package.versioncmp(nil, "1.2.3")' 
/home/josh/work/puppet-private/lib/puppet/util/package.rb:12:in `versioncmp': undefined method `scan' for nil:NilClass (NoMethodError)

Maybe use empty string instead?

desired_version = if latest_version.nil?
                    ""
                  else
                    latest_version.match(%r{^(?:[0-9]:)?(\d+\.\d+(\.\d+)?(?:\.\d+))?}).captures.first
                  end

If latest_version is nil then desired_version will still be 'latest' - But I think it makes sense to be more explicit here.

end

Puppet::Util::Package.versioncmp(desired_version, current_version) != 0
