TypeError/Unhandled exception in django.core.handlers.base.get_response() if PATH_INFO is not in env

i got the some problem

lighttpd+mod_scgi win32

It seems a windows specific problem. I got the same version of lighttpd running under linux and windows. By observing the "environ" from WSGIRequest I found windows version actually give the wrong PATH_INFO. A awkward work around can be done like the following:

replace:

self.path = environPATH_INFO?

with:

if environ.get('SCGI', None):

self.path = environREQUEST_URI?.split('?')[0]

else:

self.path = environPATH_INFO?

I ran into this problem running django (svn 5427 2007-06-02) on Dreamhost with fastcgi. PATH_INFO is empty in this environment, for whatever reason.

When APPEND_SLASH was set to False, I would get the exception described above.
When APPEND_SLASH was set to True, I would get the behavior described in #3414.

Applying the wsgi.patch from #3414 resolved the problem for me in both cases.

Closing as a duplicate of #3414 since the patch there is reported to fix this, and they appear to be the same underlying issue.

I got this error ("TypeError: unpack non-sequence") with a fairly standard setup: Debian Etch, Apache2 (prefork), mod-wsgi 1.3 (manually compiled), Python 2.4, and Django Trunk (7088).

Applying the patch from #3414 seems to have fixed it. PATH_INFO was indeed blank when I was receiving this error.

Followup: Removed the patch and instead applied the PATH_INFO hacks from the middle of this page: http://code.google.com/p/modwsgi/wiki/IntegrationWithDjango

Works perfectly with no Django hacks needed.

I encountered this error under Apache and mod_python on Linux. I'm using the Scan Alert Hackersafe vulnerability scanning service. It seems one of the things they do is post a request that is probably something like:

GET * HTTP/1.1
Host: ...

This minimal case causes the error. I can't see the exact request they're sending my server.

Here's the traceback.

This error is definitely present in SVN rev 7438.

Think i have the same problem with django SVN and apache, fastcgi, modrewrite. If a search bot requests directly the index.fcgi file, i the the error, too:

Traceback (most recent call last):

 File "/var/www/mymart/django/core/handlers/base.py", line 73, in get_response
   callback, callback_args, callback_kwargs = resolver.resolve(request.path)

TypeError: unpack non-sequence

The problem is IMHO if request.path is empty:

        urlconf = settings.ROOT_URLCONF
        resolver=RegexURLResolver(r'^/', urlconf)
        print resolver.resolve("/")
        print resolver.resolve("") # <- the problem

output:

(<function index at 0x8a8d6f4>, ('',), {})
None

My work-a-round: Define a mod_rewrite rule like this:

# Request directly the index.fcg, send 403 HTTP response (FORBIDDEN)
RewriteRule ^index.fcgi$ - [F,L]

Duplicate of #3414.

I'm able to replicate this bug with the help of django.test.client.Client; see the following:

It feels like requesting a URL without a leading slash should work, as it's checked for in the flat-pages views.

Running Django trunk, r7569.

Still a duplicate of #3414.
