Fixes django/daphne#352
Summary: When running
manage.py runserver
, daphne calls twisted'sglobalLogBeginner.beginLoggingTo
, which overrideswarnings.showwarning
. So all warnings are being disabled. More details in django/daphne#352This workaround, stores the original showwarning method and restores it when server is ready.
