Not sure about "it can always be accessed and closed/unlinked by any process later on", as each process will be spawning its own resource_tracker, using a separate pipe. Thus, unregister calls from other processes will not have any effect. The documentation is indeed unclear that processes must share the resource_tracker. Can we introduce a new flag - "persist", that would indicate no resource tracking is needed? Registering will only happen if create=True and persist=False, meaning the user accepts the creating process must outlive all other processes that could connect to the shared memory. If persist=False, the user accepts the responsibility for manual cleaning up of the allocated memory. This will allow catering to a wider range of use cases, where readers/writer processes can exit and re-connect to shared_memory as they see fit. ---------- nosy: +rauanargyn _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue39959> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
