Should only be used as a temporary logging handler, while the logging system is not fully configured. Once configured, pass any logging handlers that should have received the initial log messages to the function :func:`DeferredStreamHandler.sync_with_handlers` and all stored log records will be dispatched to the provided handlers. If anything goes wrong before logging is properly setup, all stored messages will be flushed to the handler's stream, ie, written to console. .. versionadded:: 3005 �' c s" t � �|� t|d�| _d| _d S )N)�maxlenF)�super�__init__r � _DeferredStreamHandler__messages� _DeferredStreamHandler__emitting)�self�streamZmax_queue_size�� __class__r r r + s z DeferredStreamHandler.__init__c C s | � � | j�|� | �� d S )N)�acquirer �append�release�r �recordr r r �handle0 s z DeferredStreamHandler.handlec s` | j rd S | jr#zd| _ | j�� }t� �|� W d| _ nd| _ w | js| jjs.t� �� d S d S )NTF)r r �popleftr r r �closed�flushr r r r r! 5 s � �zDeferredStreamHandler.flushr c C s< | j r | j �� }|D ] }|| u rq |�|� q | j sdS dS )zK Sync the stored log records to the provided log handlers.
