eventlet.monkey_patch是否影响threading
目录
说明
evenlet.monkey_patch()默认会绿化thread,并未看到绿化threading,为什么实际中threading被绿化了,如何证明? 测试代码如下
修改evenlet,加上标记语句
修改eventlet.green.thread.py的start_new_thread方法,加一条打印语句
def start_new_thread(function, args=(), kwargs=None):
...
print("hello: ", locals())
g = greenthread.spawn_n(__thread_body, function, args, kwargs)
return get_ident(g)
测试代码
# -*- coding:utf-8 -*-
# from eventlet import patcher
# original_threading = patcher.original('threading')
import threading as original_threading
import time
import eventlet
eventlet.monkey_patch()
def thread1_run():
while True:
print("thread1:", time.time())
time.sleep(1)
if __name__ == "__main__":
thread1 = original_threading.Thread(target=thread1_run, name="thread1", daemon=True)
print(type(thread1))
thread1.start()
e = eventlet.Event()
e.wait()
