By default, the file grows indefinitely. You can specify particular values of maxBytes and backupCount to allow the file to rollover at a predetermined size. Rollover occurs whenever the current log file is nearly maxBytes in length. If backupCount is >= 1, the system will successively create new files with the same pathname as the base file, but with extensions ".1", ".2" etc. appended to it. For example, with a backupCount of 5 and a base file name of "app.log", you would get "app.log", "app.log.1", "app.log.2", ... through to "app.log.5". The file being written to is always "app.log" - when it gets filled up, it is closed and renamed to "app.log.1", and if files "app.log.1", "app.log.2" etc. exist, then they are renamed to "app.log.2", "app.log.3" etc. respectively.

This can happen because of usage of programs such as newsyslog and logrotate which perform log file rotation. This handler, intended for use under Unix, watches the file to see if it has changed since the last emit. (A file has changed if its device or inode have changed.) If it has changed, the old file stream is closed, and the file opened to get a new stream. This handler is not appropriate for use under Windows, because under Windows open files cannot be moved or renamed - logging opens the files with exclusive locks - and so there is no need for such a handler. Furthermore, ST_INO is not supported under Windows; stat always returns zero for this value. This handler is based on a suggestion and patch by Chad J.

Flushing occurs whenever the buffer is full, or when an event of a certain severity or greater is seen. NTc C s" t j| |� || _|| _|| _dS )a; Initialize the handler with the buffer size, the level at which flushing should occur and an optional target. Note that without a target being set either here or via setTarget(), a MemoryHandler is no use to anyone! The ``flushOnClose`` argument is ``True`` for backward compatibility reasons - the old behaviour is that when the handler is closed, the buffer is flushed, even if the flush level hasn't been exceeded nor the capacity exceeded. To prevent this, set ``flushOnClose`` to ``False``.

Typically, it would be used together with a multiprocessing Queue to centralise logging to file in one process (in a multi-process application), so as to avoid file write contention between processes. This code is new in Python 3.2, but this class can be copy pasted into user code for use with earlier Python versions. c C s t jj| � || _dS )zA Initialise an instance, using the passed queue. N)r r~ r �queue)r r r r r r H s zQueueHandler.__init__c C s | j j|� dS )z� Enqueue a record. The base implementation uses put_nowait.

N)r � put_nowait)r r r r r �enqueueO s zQueueHandler.enqueuec C s" | j |� |j|_d|_d|_|S )a� Prepares a record for queuing. The object returned by this method is enqueued. The base implementation formats the record to merge the message and arguments, and removes unpickleable items from the record in-place. You might want to override this method if you want to convert the record to a dict or JSON string, or send a modified copy of the record while leaving the original intact.
