When starting a SharedMemoryManager in an interactive session, any KeyboardInterrupt event will be transmitted to the (sub)process running the shared memory server, which causes the Manager to be unusable thereafter: >>> from multiprocessing.managers import SharedMemoryManager >>> smm = SharedMemoryManager() >>> smm.start() >>> start typing something wrong KeyboardInterrupt >>> sl = smm.ShareableList(range(10)) Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/home/pierreglaser/repos/cpython/Lib/multiprocessing/managers.py", line 1342, in ShareableList with self._Client(self._address, authkey=self._authkey) as conn: File "/home/pierreglaser/repos/cpython/Lib/multiprocessing/connection.py", line 502, in Client c = SocketClient(address) File "/home/pierreglaser/repos/cpython/Lib/multiprocessing/connection.py", line 629, in SocketClient s.connect(address) FileNotFoundError: [Errno 2] No such file or directory I suggest ignoring SIGINT in the server process. |

Your patch sounds good on the principle, but can you make a patch out of it? |
