Observers

  • FIXME
  • push_simple.py: observables push notifications, execution is immediate
  • push_buggy.py: infinite recursion
  • push_origin.py: keep track of originator to avoid cycles
    • use UUID as identifier in exercise
  • push_queue.py: use the graph to add work to a queue for execution
  • delay_queue.py: split action from notification
  • delay_queue_verbose.py: run with tracing
  • logging.py: queue records actions and causes (better than verbose flag)
