def disable_foolscap_incidents(): # Foolscap-0.2.9 (at least) uses "trailing delay" in its default incident # reporter: after a severe log event is recorded (thus triggering an # "incident" in which recent events are dumped to a file), a few seconds # of subsequent events are also recorded in the incident file. The timer # that this leaves running will cause "Unclean Reactor" unit test # failures. The simplest workaround is to disable this timer. Note that # this disables the timer for the entire process: do not call this from # regular runtime code; only use it for unit tests that are running under # Trial. #IncidentReporter.TRAILING_DELAY = None # # Also, using Incidents more than doubles the test time. So we just # disable them entirely. from foolscap.logging.log import theLogger iq = NonQualifier() theLogger.setIncidentQualifier(iq)
