关闭Python线程以防止内存泄漏 [英] Close Python Thread To Prevent Memory Leak

问题描述

如何关闭Python线程以确保从内存中清除线程中内存中的所有内容?当前，我有一个以以下方式加入的线程列表:

How to I close a Python thread in order to make sure that everything in memory within a thread is cleared from memory? Currently, I have a list of threads that I join in the following manner:

for t in threadlist:
    t.join(5)

最初创建这些线程是在参数列表上循环，并通过myfunc传递给每个线程，从而将结果附加到列表中:

These threads were originally created looping over a list of arguments to pass to each thread with myfunc which appends results to a list:

threadlist = []
for r in arglist:
    t = Thread(target=myfunc, args=(r,))
    t.daemon = True
    threadlist.append(t)

当我用pympler查看内存中的内容时，线程执行的函数中的所有方式在执行后都会保留在内存中.我需要它来进行垃圾回收，就像我通常在没有线程的情况下调用myfunc一样.

When I look at what's in memory with pympler all manner of things in the function called by the thread remain in memory after this executes. I need it to garbage collect as it would if I called myfunc normally without threading.

推荐答案

已在评论中解决:

Resolved in comments:

要删除的对象包含在对象函数中.
将它们移出该对象函数，然后
到常规函数中，可以在删除后进行垃圾收集.

The objects being deleted were contained within an object function.
Moving them outside of that object function and
into a regular function allowed garbage collecting to occur following delete.
