- Fix semantics of
SIGNAL_COMPLETEso that it is not sent until the result is ready. - Use classes for the specific Huey implementations (e.g.
RedisHuey) so that it is easier to subclass / extend. Previously we just used a partial application of the constructor, which could be confusing. - Fix shutdown logic in consumer when using multiprocess worker model. Previously the consumer would perform a "graceful" shutdown, even when an immediate shutdown was requested (SIGTERM). Also cleans up the signal-handling code and ensures that interrupted tasks log a warning properly to indicate they were interrupted.
