Gmail Poll IMAP

gistfile1.rb

def self.perform
    imap = Net::IMAP.new('imap.gmail.com', 993, true)
    imap.login('MAILBOX', 'PASSWORD')

    loop do
      imap.select('INBOX')
      imap.search(['UNSEEN']).each do |message_id|
        messages = imap.fetch(message_id, ['RFC822'])

        messages.each do |message|
          m = TMail::Mail.parse message.attr['RFC822']

          m.body =~ /To\:\[BJ\-(\d+)\].*\r\n/
          fax_metadata_id = $1.to_i

          next unless fax_metadata_id

          fax_metadata = FaxMetadata.find(fax_metadata_id)

          fax_metadata.was_successful = !(m.subject =~ /^Fax Delivery Successful/).nil?

          fax_metadata.save!
        end
      end
      sleep 5
    end

    imap.logout
    # imap.disconnect
  end

If you dig through the git logs you should see where I try to implement IMAP IDLE... but then fail because of the mentioned deadlocks and/or concurrency issues. But there might be sample code hidden in the history.

Regardless, it is kind of interesting. :)
