Apache + mod_wsgi + flask应用程序:“无法获取请求的存储桶旅"日志错误 [英] Apache + mod_wsgi + flask app: "Unable to get bucket brigade for request" error in logs

问题描述

我有一个apache2/mod_wsgi/flask/python2.7应用程序.有时这样的行会出现在日志文件中:

I have a apache2/mod_wsgi/flask/python2.7 app. Sometimes such line appears in log file:

Partial results are valid but processing is incomplete: [client 45.132.96.124:34500] mod_wsgi (pid=13920): Unable to get bucket brigade for request., referer: https://my-site.com/some_url/

什么是水桶大队"?这个错误的实际含义是什么?是apache错误还是wsgi服务器错误?是什么导致此错误?如果这是一些未处理的异常-如何处理它以及在何处?

What is "bucket brigade" and what this error actually means? Is it apache error or wsgi server error? What does lead to this error? If this is some unhandled exception - how to handle it and where?

谢谢.

推荐答案

通常意味着发出请求的HTTP客户端在可以全部读取请求内容之前已断开连接.如果您正在处理手机网络上的慢客户端，那么看到这种情况并不少见.

It usually means that the HTTP client making the request dropped the connection before the request content could all be read. If you are dealing with slow clients on mobile phone networks, it is not uncommon to see this.

关于是否可以处理它，使其被忽略且不记录任何内容，我将需要查看错误消息的完整上下文，以查看它是否与 IOError 异常一起生成.Python.如果是这样，Python代码可以捕获并处理并返回500错误响应，但不记录任何内容.

As to whether you can handle it so it is ignored and nothing logged, I would need to see the complete context of the error message to see whether it is generated in conjunction with an IOError exception in Python. If it is, the Python code could catch it and deal with and return a 500 error response but not log anything.
