# This patch is required:
# For: google authentication.
# When: Running rails on a port other than 80 where a proxy server proxies to rails.
# Cause: 1. Rack is not able to figure out that it should not set the realm url port to the rails custom port in case the full_host is mentioned using
#           OmniAuth.config.full_host
#        2. OpenID tries to validate the incoming callback url with the custom port that rails is running on and throws the error "return_to #{meth.to_s} does not match".

env = Rails.env

if env != "development"
  OmniAuth.config.full_host = "http://#{env}.mysexyapp.com"

  # Fixing the realm url
  module Rack
   class OpenID
     private
     def realm_url(req)
       url = req.scheme + "://"
       url << req.host
       url
     end
   end
  end

  # Removing :port from the list of variables to verify
  module OpenID
    class Consumer
      class IdResHandler
        def verify_return_to_base(msg_return_to)
          begin
            app_parsed = URI.parse(URINorm::urinorm(@current_url))
          rescue URI::InvalidURIError
            raise ProtocolError, "current_url is not a valid URI: #{@current_url}"
          end

          [:scheme, :host, :path].each do |meth|
            if msg_return_to.send(meth) != app_parsed.send(meth)
              raise ProtocolError, "return_to #{meth.to_s} does not match"
            end
          end
        end
      end
    end
