Hi, I just opened a PR implementing a fix very similar to your suggestions. I am using advisory locking using fcntl.flock. And I am locking on file descriptors. If you see my PR, in resource tracker I am opening a file "/dev/shm/<shm_name>", and trying to acquire exclusive lock on the same. And it's working great on Linux. Since, resource_tracker is spawned as a different process, I can't directly use file descriptors. But macOS doesn't have any memory mapped files created by shm_open in /dev/shm. In fact, it doesn't store any reference to memory mapped files in the filesystem. Therefore it get's difficult to get the file descriptor in resource tracker. Also, is there a good way to pass file descriptors between processes. Any ideas on the above issue will be much appreciated. ---------- title: Persistence of Shared Memory Segment after process exits -> Consistency of Unix's shared_memory implementation with windows _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue37754> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
