[ZODB-Dev] Thread Safety, Reaimed

[Stefan H. Holek]

Hm, then try a Borg pattern, maybe.

  # Module GlobalLock.py
  import threading

  class GlobalLock:
      __shared_state = {
          '_lock': threading.Lock()
          }
      def __init__(self):
          self.__dict__ = self.__shared_state
      def acquire(self):
          self._lock.acquire()
      def release(self):
          self._lock.release()

Now you can do things like:

  from GlobalLock import GlobalLock

  GlobalLock().acquire()
  ...
  GlobalLock().release()

HTH,
Stefan
