where occasionally the scheduler\nservice gets into a state where many requests fail in it with\nCellTimeout errors. Example:\n\n  Timed out waiting for response from cell \u003ccell uuid\u003e\n\nThrough the use of much DNM patch debug logging in oslo.db, it was\nrevealed that service child processes (workers) were sometimes starting\noff with already locked internal oslo.db locks. This is a known issue\nin python [1] where if a parent process forks a child process while a\nlock is held, the child will inherit the held lock which can never be\nacquired.\n\nThe python issue is not considered a bug and the recommended way to\nhandle it is by making use of the os.register_at_fork() in the oslo.db\nto reinitialize its lock. The method is new in python 3.7, so as long\nas we still support python 3.6, we must handle the situation outside of\noslo.db.\n\nWe can do this by clearing the cell cache that holds oslo.db database\ntransaction context manager objects during service start(). This way,\nwe get fresh oslo.db locks that are in an unlocked state when a child\nprocess begins.\n\nWe can also take this opportunity to resolve part of a TODO to clear\nthe same cell cache during service reset() (SIGHUP) since it is another\ncase where we intended to clear it. The rest of the TODO related to\nperiodic clearing of the cache is removed after discussion on the\nreview, as such clearing would be unsynchronized among multiple\nservices and for periods of time each service might have a different\nview of cached cells than another.\n\nCloses-Bug: #1844929\n\n[1] https://bugs.python.org/issue6721\n\nChange-Id: Id233f673a57461cc312e304873a41442d732c051\n(cherry picked from commit 941559042f609ee43ff3160c0f0d0c45187be17f)\n(cherry picked from commit 88205a4e911268dae7120a6a43ff9042d1534251)\n","web_links":[{"name":"gitea","tooltip":"Open in GitWeb","url":"https://opendev.org/openstack/nova/commit/4de766006d9432a7ccbcf6a4d4232db472b2f0e1"}],"resolve_conflicts_web_links":[{"name":"gitea","tooltip":"Open in GitWeb","url":"https://opendev.org/openstack/nova/commit/4de766006d9432a7ccbcf6a4d4232db472b2f0e1"}]},"branch":"refs/heads/stable/stein"}},"requirements":[],"submit_records":[],"submit_requirements":[]}
