Integration with twisted.python.log.
Function publishToNewObserver Publish an old-style (twisted.python.log) event to a new-style (twisted.logger) observer.
def publishToNewObserver(observer, eventDict, textFromEventDict): (source)
Publish an old-style (twisted.python.log) event to a new-style (twisted.logger) observer.
observer:ILogObserverA new-style observer to handle this event.
eventDict:Dict[str, Any]An old-style, log event.
textFromEventDict:Callable[[Dict[str, Any]], Optional[str]]callable that can format an old-style event as a string. Passed here rather than imported to avoid circular dependency.
It's possible that a new-style event was sent to a LegacyLogObserverWrapper, and may now be getting sent back to a new-style observer. In this case, it's already a new-style event, adapted to also look like an old-style event, and we don't need to tweak it again to be a new-style event, hence this checks for already-defined new-style keys.
