Hi,
I have a doubt. Supose that i have the minimun class below:
class db:
def __init__(self):
self.db = {}
def read(self, key):
return self.db[key]
def write(self, key, value):
self.db[key] = value
and an object of this class is shared among some threads. Is it possible
that in a read, the method return a value that is not an old or a new value?
In other words, is it possible that a 'read' return (due to a 'write' at the
same time by another thread) an invalid value that was never supposed to be
there?
Thanks,
Flavio Preto
