[chef] Re: Custom Ohai Plugin Weirdness

I suspect the http.request is throwing an exception (so it does not execute the subsequent lines).

I've been trying to write an ohai plugin to pull a piece of data from a URL. The plugin looks like this:

require 'rexml/document'
include REXML
Ohai.plugin(:SliceLatestVersion) do
  provides "slice/latest_version"
  def create_objects
    slice Mash.new
  end
  collect_data(:default) do
    create_objects
    uri = URI.parse("https://172.30.1.213/artifactory/simple/slice-stable-local/com/slice/core/slice-dt/maven-metadata.xml")
   http = Net::HTTP.new(uri.host, uri.port)
    http.use_ssl = true
    http.verify_mode = OpenSSL::SSL::VERIFY_NONE
    request = Net::HTTP::Get.new(uri.request_uri)
    response = http.request(request)
    @data = "response.body   xmldoc = Document.new data
    latest = XPath.first(xmldoc, "//metadata/versioning/latest")
    slice['latest_version'] = "B" #latest.text
  end
end

Now, here's the weird part. The mash slice ends up being set to {}. This should not happen considering I'm setting it to a literal value there right at the end. If I remove all that HTTP code before it, the mash slice becomes { 'latest_version': 'B' }. How is this possible?
