Whilequeuelibandpython-pqueuecannot fulfil all of above. After some try, I found it’s hard to achieve based on their current implementation without huge code change. this is the motivation to start this project.

一般通用(非python层面)的进程线程间通信的常见方式: 进程间通信: 管道(pipe):管道是一种半双工的通信方式,数据只能单向流动,而且只能在具有亲缘关系的进程间使用进程间的亲缘关系通常是指父子进程关系。 命名管道(named pipe/FIFO):命名管道也是半双工的通信方式,但是它允许无亲缘关系进程间的通信。 信号量(semophon...

for i in range(10): t = threading.Thread(target=consumer, args=(i,)) t.start() multiprocessing模块 multiprocessing是python的多进程管理包,和threading.Thread类似。直接从侧面用subprocesses替换线程使用GIL的方式,由于这一点,multiprocessing模块可以让程序员在给定的机器上充分的利用CPU。
It is especially useful in threaded programming when information must be exchanged safely between multiple threads. TheQueueclass in this module implements all the required locking semantics. It depends on the availability of thread support in Python; see thethreadingmodule. ...
