New submission from Pierre Glaser <[email protected]>:
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.
