好像还是用抛异常来解决超时杀线程比较方便


import threading
import time
import inspect
import ctypes

def _async_raise(tid, exctype):
"""raises the exception, performs cleanup if needed"""
tid = ctypes.c_long(tid)
if not inspect.isclass(exctype):
exctype = type(exctype)
res = ctypes.pythonapi.PyThreadState_SetAsyncExc(tid, ctypes.py_object(exctype))
if res == 0:
raise ValueError("invalid thread id")
elif res != 1:
# """if it returns a number greater than one, you're in trouble,
# and you should call it again with exc=NULL to revert the effect"""
ctypes.pythonapi.PyThreadState_SetAsyncExc(tid, None)
raise SystemError("PyThreadState_SetAsyncExc failed")

def stop_thread(thread):
_async_raise(thread.ident, SystemExit)

class TestThread(threading.Thread):
def run(self):
print "begin"
while True:
time.sleep(0.1)
print "end"
if __name__ == "__main__":
t = TestThread()
t.start()
time.sleep(1)
