Research direction
Start in Lib/multiprocessing/managers.py at the SharedMemoryManager.ShareableList method near the bottom of the file, then compare it with shared_memory.ShareableList's name parameter. Done means the manager method accepts and forwards name while retaining its tracking and cleanup behavior.
Written by the indexing model from the issue text.
Description
Feature or enhancement
I would like to pass a name for shared list from SharedMemoryManager but I apparently cannot do this.
with SharedMemoryManager() as smm:
my_shared_list = smm.ShareableList(sequence=range(10),name="special name")
pass
What I get:
my_shared_list = smm.ShareableList(sequence=range(10),name="special name")
TypeError: SharedMemoryManager.ShareableList() got an unexpected keyword argument 'name'
Possible solution
Just change method ShareableList in the bottom of this source file to following:
def ShareableList(self, sequence, name=None):
"""Returns a new ShareableList instance populated with the values
from the input sequence, to be tracked by the manager."""
with self._Client(self._address, authkey=self._authkey) as conn:
sl = shared_memory.ShareableList(sequence=sequence,name=name)
try:
dispatch(conn, None, 'track_segment', (sl.shm.name,))
except BaseException as e:
sl.shm.unlink()
raise e
return sl
I wonder
Why this feature is not implemented from the very beggining?
