如何强制线程停止 [英] How to force a thread to stop
问题描述
大家好，
有没有办法让创建和启动线程的程序也停止
吧。
（我的用法是暂停）。
例如
thread = threading.Thread（target = Loop.testLoop）
thread.start（）＃这个线程预计在一秒钟内完成
thread.join（2）#Or time.sleep（2）？
如果thread.isAlive（）：
#thread可能遇到问题并挂起
＃这里应该停止什么线程???? ??
请注意，我不想改变目标（太多），因为存在许多可能的
目标，
汇集了数千行代码。
谢谢，
Hans
Hi all,
Is there a way that the program that created and started a thread also stops
it.
(My usage is a time-out).
E.g.
thread = threading.Thread(target=Loop.testLoop)
thread.start() # This thread is expected to finish within a second
thread.join(2) # Or time.sleep(2) ?
if thread.isAlive():
# thread has probably encountered a problem and hangs
# What should be here to stop thread ??????
Note that I don''t want to change the target (too much), as many possible
targets exist,
together thousands of lines of code.
Thanks,
Hans

不，Python没有线程方法，而且它的缺席不是
的疏忽。线程通常还有很多重要的事情需要做，例如释放锁定共享数据的
;在任意时间杀死它们
往往会使系统处于不一致状态。
No, Python has no threadicide method, and its absence is not an
oversight. Threads often have important business left to do, such
as releasing locks on shared data; killing them at arbitrary times
tends to leave the system in an inconsistent state.
if thread.isAlive（）：
#thread可能遇到问题并挂起
＃这里应该停止线程??????
if thread.isAlive():
# thread has probably encountered a problem and hangs
# What should be here to stop thread ??????
此时，为时已晚。尝试编写代码，这样你的线程就不会挂起。
当你想要终止程序时，Python会让你安排线程死掉，线程''的Thread.setDaemon（）。

At this point, it''s too late. Try to code so your threads don''t hang.
Python does let you arrange for threads to die when you want to
terminate the program, with threading''s Thread.setDaemon().

嗨！

我喜欢这个词...

也许避免线程和使用进程的另一个原因是什么？
Perhaps another reason to avoid threads and use processes instead?
