Python开发【笔记】：关闭线程的方法

1、通过API进行线程关闭

import threading
import time
import inspect
import ctypes
 
def _async_raise(tid, exctype):
    """raises the exception, performs cleanup if needed"""
    print(tid,exctype)
    tid = ctypes.c_long(tid)
    print tid
    if not inspect.isclass(exctype):
        print exctype
        exctype = type(exctype)
    print exctype
    res = ctypes.pythonapi.PyThreadState_SetAsyncExc(tid, ctypes.py_object(exctype))
    print res
    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:
            # print 'run'
            time.sleep(0.1)
        print "end"
if __name__ == "__main__":
    t = TestThread()
    t.start()
    time.sleep(1)
    stop_thread(t)
    print "stoped"

注：杀不起正在阻塞的线程
