How to debug python application under uWSGI?

Question

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

here is the code:

def a         


        

Answer 1

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

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

--honour-stdin

Answer 2

try this

uwsgi --http 127.0.0.1:7777  --wsgi-file uwsgi_test.py --logto /path/to/log/log.txt

Answer 3

Install remote debugger.

pip install remote-pdb

Set breakpoint somewhere in application.

from remote_pdb import RemotePdb
RemotePdb('127.0.0.1', 4444).set_trace()

Connect to remote debugger via telnet

# 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.
