How to debug python application under uWSGI?
提问by Anderson
When I'm trying to use python pdb debugger under uWSGI, the execution doesn't stop on breakpoint, it just return trackback.
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。
here is the code:
这是代码：
def application(env, start_response):
import pdb; pdb.set_trace()
start_response('200 OK', [('Content-Type','text/html')])
return "Hello World"
this is how I run it:
这就是我运行它的方式：
uwsgi --http 127.0.0.1:7777 --wsgi-file uwsgi_test.py
and this is what I get:
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

Being a server, uWSGI closes the stdin (effectively it remaps it to /dev/null).
作为服务器，uWSGI 关闭标准输入（有效地将其重新映射到 /dev/null）。
If you need stdin (as when you need a terminal debugger) add:
如果您需要 stdin（就像您需要终端调试器一样），请添加：
--honour-stdin

try this
尝试这个
uwsgi --http 127.0.0.1:7777 --wsgi-file uwsgi_test.py --logto /path/to/log/log.txt

Install remote debugger.
安装远程调试器。
pip install remote-pdb
Set breakpoint somewhere in application.
在应用程序的某处设置断点。
from remote_pdb import RemotePdb
RemotePdb('127.0.0.1', 4444).set_trace()
Connect to remote debugger via telnet
通过 telnet 连接到远程调试器
# Restart uwsgi to pick up changes
...
# Trigger the breakpoint, (any action to evaluate the set_trace call)
...
# Connect to debugger
telnet 127.0.0.1 4444
You will likely want to run uWSGI with a single worker/thread, so that the remote debuggers do not step on one another.
您可能希望使用单个工作线程/线程运行 uWSGI，以便远程调试器不会相互干扰。
