Victor Stinner 356de021d7 [3.12] gh-109047: concurrent.futures catches RuntimeError (#109810) (#110126) ... gh-109047: concurrent.futures catches PythonFinalizationError (#109810) concurrent.futures: The *executor manager thread* now catches exceptions when adding an item to the *call queue*. During Python finalization, creating a new thread can now raise RuntimeError. Catch the exception and call terminate_broken() in this case. Add test_python_finalization_error() to test_concurrent_futures. concurrent.futures._ExecutorManagerThread changes: * terminate_broken() no longer calls shutdown_workers() since the call queue is no longer working anymore (read and write ends of the queue pipe are closed). * terminate_broken() now terminates child processes, not only wait until they complete. * _ExecutorManagerThread.terminate_broken() now holds shutdown_lock to prevent race conditons with ProcessPoolExecutor.submit(). multiprocessing.Queue changes: * Add _terminate_broken() method. * _start_thread() sets _thread to None on exception to prevent leaking "dangling threads" even if the thread was not started yet.
