好的,首先检查以下代码:
class DemoClass():
def __init__(self):
#### I really want to know if self.Counter is thread-safe.
self.Counter = 0
def Increase(self):
self.Counter = self.Counter + 1
def Decrease(self):
self.Counter = self.Counter - 1
def DoThis(self):
while True:
Do something
if A happens:
self.Increase()
else:
self.Decrease()
time.sleep(randomSecs)
def DoThat(self):
while True:
Do other things
if B happens:
self.Increase()
else:
self.Decrease()
time.sleep(randomSecs)
def ThreadSafeOrNot(self):
InterestingThreadA = threading.Thread(target = self.DoThis, args = ())
InterestingThreadA.start()
InterestingThreadB = threading.Thread(target = self.DoThat, args = ())
InterestingThreadB.start()
我遇到了与上述相同的情况。我真的想知道它是否是线程安全的 self.Counter
,如果不是,我有什么选择?我只能想到 threading.RLock()
锁定此资源,有什么更好的主意吗?
Python 实例变量是线程安全的吗?
