This function is only used by client code which is maintaining its own threadpool. To run a function in the reactor's threadpool, use C{deferToThread}. @param reactor: The reactor in whose main thread the Deferred will be invoked. @param threadpool: An object which supports the C{callInThreadWithCallback} method of C{twisted.python.threadpool.ThreadPool}. @param f: The function to call. @param *args: positional arguments to pass to f. @param **kwargs: keyword arguments to pass to f. @return: A Deferred which fires a callback with the result of f, or an errback with a L{twisted.python.failure.Failure} if f throws an exception. c s& | r�� � j|� n�� � j|� d S �N)�callFromThread�callbackZerrback)Zsuccess�result��d�reactor� �:/usr/lib/python3/dist-packages/twisted/internet/threads.py�onResult/ s z#deferToThreadPool.<locals>.onResult)r ZDeferredZcallInThreadWithCallback)r Z threadpool�f�args�kwargsr r r r �deferToThreadPool s r c O s$ ddl m} t||�� | f|�|�S )aw Run a function in a thread and return the result as a Deferred. @param f: The function to call. @param *args: positional arguments to pass to f. @param **kwargs: keyword arguments to pass to f. @return: A Deferred which fires a callback with the result of f, or an errback with a L{twisted.python.failure.Failure} if f throws an exception. r �r )�twisted.internetr r Z getThreadPool)r r r r r r r � deferToThread: s ���r c C s | D ]\}}}|||� qdS )z" Run a list of functions.

If C{f} returns a L{Deferred} which fires with a L{Failure}, C{blockingCallFromThread} will raise that failure's exception (see L{Failure.raiseException}). c s" t j�f� ���} | ��j� d S r )r Z maybeDeferredZaddBothZput)r ��ar �kw�queuer r �_callFromThreadt s z/blockingCallFromThread.<locals>._callFromThread)�Queuer �get� isinstancer ZFailureZraiseException)r r r r r r r r r �blockingCallFromThread] s r# )�__doc__Z __future__r r Ztwisted.python.compatr r r Ztwisted.pythonr r r r r r r r# �__all__r r r r �<module> s $ !�
