为什么Django开发服务器挂在这个管理工具JS文件上？ [英] Why does the Django development server hang on this admin tool JS file?

问题描述

定期使用Django管理工具时，它会挂起并停止响应请求，直到重新启动。每当挂起时，日志中的最后一行是：

Periodically, when using the Django admin tool, it hangs and stops responding to requests until it is restarted. Whenever it hangs, the last line in the log is:

GET / admin / jsi18n / HTTP / 1.1200 2158

"GET /admin/jsi18n/ HTTP/1.1" 200 2158

挂起似乎发生在POST之后（如查看添加对象的结果）。它发生在各种不同的模型，是不可预测的，据我所知。唯一的常量是对该Javascript文件的GET请求。此外，挂起之间的时间有所不同：有时您可以使用管理工具添加一个小时的对象，有时不能持续5分钟。

The hang seems to occur after a POST (like when viewing the results of adding an object). It happens with a variety of different models and is unpredictable, as far as I can tell. The only constant is the GET request to that Javascript file. Also, the time between hangs varies: sometimes you can add objects with the admin tool for an hour, sometimes it can't last 5 minutes.

性能方面，框似乎没有受到很大的压力（负载平均值为0.17-0.20）

Performance-wise, the box does not appear to be under much stress (load average of 0.17-0.20)

它最近输出一个看起来很有趣的错误，虽然它恢复了自己，并在以后继续提供服务：

It recently output an error that looks interesting, though it recovered itself and kept serving responses afterwards:

[18/Aug/2011 13:19:50] "GET /admin/jsi18n/ HTTP/1.1" 200 2158

推荐答案

很可能是因为您使用Google Chrome。这将使多达一个连接到Web服务器的连接，在Django Dev服务器的情况下，这是不好的。你有两个选择。
使用

Most likely this is because of you using Google Chrome. Which will make more then one connection to a web-server, which in the case of the Django Dev server it's no good. You have two options. Either use

• Django并发服务器


• 使用生产服务器设置您的开发者服务器（不推荐，更复杂）


• 使用Firefox，告诉Chrome停止多个连接


• 使用单独的服务器在计算机上托管静态文件。喜欢Lighttpd或某些东西。

• Django Concurrent Server
• Setup your dev-server using a production server (Don't recommend, more complex)
• Use Firefox, tell Chrome to stop multiple connections
• Host your static files on your computer using a separate server. Like Lighttpd or something.
