_cpwsgiserver.py should coerce response header values to strings

Status: closed (wontfix)

While using _cpwsgiserver.py with my pylons WSGI application I am getting an exception raised at http://www.cherrypy.org/browser/trunk/cherrypy/_cpwsgiserver.py#L326 stating "TypeError?: cannot concatenate 'str' and 'int' objects" because my Content-Length response header is an int.

I looked in the WSGI PEP and couldn't find a requirement that header values be strings and I did a quick survey of several WSGI apps and they all seem to use an int for the Content-Length header; so I think the response header values should be automatically coerced to strings in _cpwsgiserver.

I've only been using _cpwsgiserver for a total of 30 minutes so hopefully I'm not missing something obvious.

Thanks,

Although the PEP is arguably vague on this point, wsgiref and paste.lint are not; for example:

assert type(val) is StringType,"Header values must be strings"

It would be in everyone's best interest for you to fix the application(s). However, we should probably decide this on web-sig, so I'm going to keep this open for now.

  • status changed from new to closed.
  • resolution set to wontfix.
  • milestone set to 3.0.

And here's the answer: http://mail.python.org/pipermail/web-sig/2006-September/002239.html

"I would urge you to have CherryPy reject servers or middleware providing integer content-length as broken, preferably with an error that indicates the application is not WSGI-compliant."

I added the error message in [1341].

This bug is occuringin Paste's FileApp? which serves static files. It's been fixed in Paste trunk.
