在gevent中，如何转储所有正在运行的greenlet的堆栈跟踪? [英] In gevent, how can I dump stack traces of all running greenlets?

问题描述

出于调试目的，我想遍历所有greenlet并获取其跟踪记录-如何使用gevent做到这一点?

For debugging purposes, I would like to iterate over all greenlets and obtain their trace traces -- how can I do that with gevent?

基本上，我想做与 this 相同的gevent.

Basically, I would like to do the gevent equivalent of this.

推荐答案

您可以使用gc模块遍历堆上的所有对象并搜索greenlets. Greenlets将堆栈跟踪存储为属性gr_frame.

You can use the gc module to iterate through all the objects on the heap and search for greenlets. Greenlets store the stack traces as an attribute gr_frame.

import gc
import traceback
from greenlet import greenlet

for ob in gc.get_objects():
    if not isinstance(ob, greenlet):
        continue
    if not ob:
        continue
    log.error(''.join(traceback.format_stack(ob.gr_frame)))
