Thread-safe: can be used by multi-threaded producers and multi-threaded consumers. Recoverable: Items can be read after process restart. Green-compatible: can be used ingreenletoreventletenvironment. Whilequeuelibandpython-pqueuecannot fulfil all of above. After some try, I found it’s hard to...

The mechanism used by the CPython interpreter to assure that only one thread executes Python bytecode at a time. This simplifies the CPython implementation by making the object model (including critical built-in types such as dict) implicitly safe against concurrent access. Locking the entire inte...

Threading模块 包括Thread、Condition、Event、Lock、Rlock、Semaphore等类。 1、Thread类可以实例化一个线程t,(target=) t.start() Thread方法如下: getName:返回线程t的名称、setName设置线程t的名称 isAlive:判断一个线程是否是活动的,也就是线程的状态在t.start和t.run之间 ...
