When invoked from the reactor thread, previous implementations of L{IReactorThreads.callFromThread} would skip the pipe/socket based wake up step, assuming the reactor would wake up on its own. However, this resulted in the reactor not noticing an insert into the thread queue at the right time (in this case, after the thread queue has been processed for that reactor iteration). c s � � � d S r )r r �r r r � threadCallS s zAThreadTestsBuilder.test_delayedCallFromThread.<locals>.threadCallr �< � N)r � callLater�callFromThreadZsecondsr r )r r$ ZbeforeZafterr r# r �test_delayedCallFromThreadE s z-ThreadTestsBuilder.test_delayedCallFromThreadc sP | � � � g �� �fdd�}� �d� j� j|� | �� d� | ��t�� g� dS )z� A function scheduled with L{IReactorThreads.callFromThread} invoked from another thread is run in the reactor thread. c s �� t�� � � �� d S r )r � threading� currentThreadr r �r �resultr r r$ x s z:ThreadTestsBuilder.test_callFromThread.<locals>.threadCallr � N)r r' � callInThreadr( r r r* r+ )r r$ r r, r �test_callFromThreadp s � z&ThreadTestsBuilder.test_callFromThreadc C sB | � � }t|�� �}|�|j� | �|� t�� | �|� � dS )a0 When the reactor stops, L{ReactorBase._stopThreadPool} drops the reactor's direct reference to its internal threadpool and removes the associated startup and shutdown triggers. This is the case of the thread pool being created before the reactor is run.

Some implementation background: The thread pool is started with callWhenRunning, which only returns a system trigger ID when it is invoked before the reactor is started. This is the case of the thread pool being created after the reactor is started. c s �� t� �� �� � �� d S r )r r r r r �r ZthreadPoolRefsr r �acquireThreadPool� s z[ThreadTestsBuilder.test_stopThreadPoolWhenStartedAfterReactorRan.<locals>.acquireThreadPoolr N)r r r r1 r2 r3 )r r7 r r6 r �-test_stopThreadPoolWhenStartedAfterReactorRan� s z@ThreadTestsBuilder.test_stopThreadPoolWhenStartedAfterReactorRanc C sZ | � � }t|�� �}|�d� |jjdkrB| �|j� | �|� nt � � | �|� � dS )a[ When the reactor has its shutdown event fired before it is run, the thread pool is completely destroyed. For what it's worth, the reason we support this behavior at all is because Trial does this. This is the case of the thread pool being created without the reactor being started at al.
