'NoneType' object has no attribute 'format'

[TheML9I]

If you use uwsgi with parameter optimize=2 you can get error with using it:

AttributeError at /mymodule/api/
'NoneType' object has no attribute 'format'

interpreter info:

Python Executable: /home/httpd/app/bin/uwsgi
Python Version: 2.7.5

additional:

-O Turn on basic optimizations. This changes the filename extension for compiled (bytecode) files from .pyc to .pyo. See also PYTHONOPTIMIZE.
-OO Discard docstrings in addition to the -O optimizations.

As possible solution add for py23compat.py

return s.format(u='u') if s else s

Any ideas?

Thnx!

You are removing function docstrings with an optimization flag, and this is causing errors with the compat code because it expects docstrings to exist. Do I understand your issue correctly? If so, this seems like it will be a straightforward fix.

As a side note, the py23compat.py file hasn't existed in natsort since version 4.0.1... version 4.0.3 was released almost a year ago, and there is now version 5.0.0. Is there a reason you haven't upgraded?

[SethMMorton]

Version 5.0.1 incorporates this update.

You're right.

We're using ver. 3.5 in our local PYPI. But we checked ver. 5 installed from common PYPI and had similar error. I think your last fix solve it. As soon as possible i check it! Thanks!
