如何在uWSGI下调试python应用程序? [英] How to debug python application under uWSGI?

问题描述

当我尝试在 uWSGI 下使用 python pdb 调试器时，执行不会在断点处停止，它只是返回引用.

When I'm trying to use python pdb debugger under uWSGI, the execution doesn't stop on breakpoint, it just return trackback.

代码如下:

def application(env, start_response):
    import pdb; pdb.set_trace()
    start_response('200 OK', [('Content-Type','text/html')])
    return "Hello World"

这是我运行它的方式:

uwsgi --http 127.0.0.1:7777  --wsgi-file uwsgi_test.py

这就是我得到的:

/home/andrey/Development/ttt/uwsgi_test.py(3)application()
-> start_response('200 OK', [('Content-Type','text/html')])
(Pdb) 
Traceback (most recent call last):
  File "uwsgi_test.py", line 3, in application
    start_response('200 OK', [('Content-Type','text/html')])
  File "uwsgi_test.py", line 3, in application
    start_response('200 OK', [('Content-Type','text/html')])
  File "/usr/lib/python2.7/bdb.py", line 48, in trace_dispatch
    return self.dispatch_line(frame)
  File "/usr/lib/python2.7/bdb.py", line 67, in dispatch_line
    if self.quitting: raise BdbQuit
bdb.BdbQuit
[pid: 11421|app: 0|req: 1/1] 127.0.0.1 () {32 vars in 366 bytes} [Sun Aug 25 13:12:06 2013] GET / => generated 0 bytes in 63 msecs (HTTP/1.1 500) 0 headers in 0 bytes (0 switches on core 0)

推荐答案

作为服务器，uWSGI 关闭了标准输入(实际上它重新映射到/dev/null).

Being a server, uWSGI closes the stdin (effectively it remaps it to /dev/null).

如果您需要 stdin(就像您需要终端调试器一样)，请添加:

If you need stdin (as when you need a terminal debugger) add:

--honour-stdin
