Question

我正在运行基于tornado.testing.AsyncHTTPTestCase的测试用例，偶尔会在日志中看到这个堆栈跟踪。它似乎是随机发生的，因此多次运行测试套件有时会遇到这种情况。

这是一个tornado 3.2错误还是我应该如何处理这个例外？

它似乎不会影响我的任何测试结果，但我对这样的随机异常感到不满意。

OverflowError: can't convert negative int to unsigned

Answer 1

我之前没有见过这个，但看起来套接字对象已被关闭（将其文件描述符更改为-1），而IOStream仍在尝试从中读取它。您是否在测试中进行任何异常清理或直接进入任何IOStream以访问套接字对象？
