线程垃圾回收 [英] Thread garbage collection

问题描述

如果不再有Python threading.Thread引用，但它仍在运行，是否会对其进行垃圾回收?

Will a Python threading.Thread ever be garbage collected if there is no longer any reference to it but it's still running?

# Start a thread with no reference
Thread(target=some_long_running_function).start()
# Do lots of other stuff

推荐答案

我相信Threading模块在运行时包含对线程的引用，然后在Thread run()方法完成后将其清除.我无法评论模块的内部及其如何实现此功能，但是我相信可以通过

I believe the Threading module contains a reference to the thread whilst it is running and is then cleaned when the Thread run() method has finished. I cannot comment on the internals of the module and how it accomplishes this but I believe these references (references to active threads) can be accessed via threading.enumerate()
