Hi,
I have a method which increments an attribute on the current object. I
have created a thread lock so that multiple threads accessing the method
simultaneously cannot stuff up the attribute value:
lock = thread.allocate_lock()
def nextOrderNumber(self):
lock.acquire()
self._order_number = self._order_number + 1
lock.release()
return str(self._order_number)
My concern is that even though a second thread is halted at
"lock.acqure()" while the first thread updates the order_number, that
the second thread has an 'out of date' version of 'self' with the
original order_number value in it, hence, is still returning the
incorrect order_number.
Do I need to explicity get the order_number attribute from the ZODB
somehow, rather than grabbing it from 'self'?
