There's no point deleting them as other threads may continue to hold references to them; and by disabling them, you stop them doing any logging. However, don't disable children of named loggers, as that's probably not what was intended by the user. Also, allow existing loggers to NOT be disabled if disable_existing is false.

These will be sent as a file suitable for processing by fileConfig(). Returns a Thread object on which you can call start() to start the server, and which you can join() when appropriate. To stop the server, call stopListening(). Use the ``verify`` argument to verify any bytes received across the wire from a client. If specified, it should be a callable which receives a single argument - the bytes of configuration data received across the network - and it should return either ``None``, to indicate that the passed in bytes could not be verified and should be discarded, or a byte string which is then passed to the configuration machinery as normal. Note that you can return transformed bytes, e.g. by decrypting the bytes passed in. c @ s e Zd ZdZdd� ZdS )z#listen.<locals>.ConfigStreamHandlerz� Handler for a logging configuration request.
