这是一些奇怪的回归，我只能在我们拥有的更强大的生产机器上重现。

def test_foo(self):
    res = self._run_job( ....)
    self.assertTrue("Hello Input!" in res.json()["stdout"], res.text)
    .........

def _run_job(self, cbid, auth, d):    
    .........
    while True:
        res = requests.get(URL+"/status/"+status_id, auth=auth)   <--- hangs here
        if res.json()["status"] != "Running":
            break
        else:
            time.sleep(2)
    ..........

我必须打破这个过程，这是回溯：

为什么gevent参与？这是一个功能测试。它只通过requests库发出 HTTP 请求，所以可能是switch指requests.

但是作为一个简单的循环，这怎么可能失败呢？

为什么gevent参与？

库gevent猴子修补了一些标准模块以使它们协作。替换time.sleep为gevent.sleep更改之一。

你在gevent中打补丁吗？

它可能正在打开网络请求并且由于某种原因永远不会回来。我会说现在停止猴子修补，并把它放在你需要的地方。

可能现在请求是异步的，它立即返回，然后休眠（再次异步）和请求，然后冲洗/重复......
