在python中监控线程同步 [英] Monitor thread synchronization in python

问题描述

有没有什么办法可以像java方法同步一样在python类中使用monitor线程同步来保证线程安全和避免竞争条件?

我想要一个类似监视器的同步机制，它只允许在我的类或对象中调用一个方法

解决方案

你可能想看看 python 线程接口.对于简单的互斥功能，您可以使用 Lock 对象.您可以使用 with 语句轻松完成此操作，例如:

<代码>...锁 = 锁()...与(锁定):# 这段代码一次只会被一个线程执行# 当线程退出'with'块时，锁被释放...

另请参阅此处，了解 Python 中不同线程同步机制的概述.>

Java 的 synchronized 没有 python 语言构造(但我想它可以使用装饰器构建)

Is there any way to use monitor thread synchronization like java methods synchronization,in python class to ensure thread safety and avoid race condition?

I want a monitor like synchronization mechanism that allows only one method call in my class or object

解决方案

You might want to have a look at python threading interface. For simple mutual exclusion functionality you might use a Lock object. You can easily do this using the with statement like:

...
lock = Lock()
...
with (lock):
  # This code will only be executed by one single thread at a time
  # the lock is released when the thread exits the 'with' block
  ...

There is no python language construct for Java's synchronized (but I guess it could be built using decorators)
