Class Method Details

.close_connections ⇒ Object

Temporary hack. MacRuby crashes on the ensure clause above when the server thread is killed. This function allows for manually closing the connections.

def stop
  if @thread
    @thread.kill
    # Kill can return before the thread has finished execution. A Ruby bug?
    @thread.join
    @thread = nil
  end
end

.thread ⇒ Object

This makes it easier for code to check if it runs inside the server thread.
