Wsgi Error

[Adrian Ribao]

I'm testing a site with latest django trunk and latest development version of django-page-cms.

When I try to add a new page, I get this error:

File "path/env/src/django-page-cms/pages/http.py", line 21, in get_request_mock
    'HTTP_HOST': 'testhost',

File "path/env/lib/python2.5/site-packages/django/core/handlers/wsgi.py", line 137, in __init__
    if type(socket._fileobject) is type and isinstance(self.environ['wsgi.input'], socket._fileobject):

KeyError: 'wsgi.input'

Possibly related to ticket #14602 which resulted in changeset [14453], looking at the erro raised and the lines involved.

I'm in [14677] and still not working.

In an effort to rule in or out certain configurations:

• What environment is this being run under: runserver/apache/nginx/appengine etc?
• Are you able to replicate the problem outside of django-page-cms?
• Have you tried rolling back to an older django revision (or stable release) to see if the problem persists?

I apologise if these seem like trite questions, or obvious things to check, but the original ticket seems to have enough unknown variables to make testing the problem onerous.

I'm using Apache + modwsgi 2.5, and I wasn't able to replicate the problem outside django-page-cms.

It was working with the previous version, but I don't remember the revision.

I can't find the problem here. The enviroment says it's running in test mode using port 8000.

parth/env/src/django-page-cms/pages/http.py in get_request_mock
'HTTP_HOST': 'testhost', 

environ: {'HTTP_HOST': 'testhost', 'PATH_INFO': u'/', 'REQUEST_METHOD': 'GET', 'SCRIPT_NAME': u'', 'SERVER_NAME': 'test', 'SERVER_PORT': '8000'}

According to the ​svn log, beyond the change-set previously mentioned there's also [14494] & [14493]. Looking at them briefly, it seems like the regression tests in [14494] specifically provide the wsgi.input key in the environ dictionary, which is notably absent from the django-page-cms mock WSGIRequest I can see on github.

I'm not familiar enough with the WSGI code (or indeed the spec) to speak any further on the subject, but it may be well intentionally required now, in which case django-page-cms will need to catch up, and possibly the change needs to be documented (providing a note on backwards compatibility, if such is the case?)

Hopefully someone with more knowledge on the internals (russellm recently, by the looks of things) will get the opportunity to look at this.

[Russell Keith-Magee]

If django-page-cms is providing a mock of WSGIRequest and it doesn't provide wsgi.input, then it isn't a complete mock. ​PEP333 specifies that WSGI requests *must* provide a number of wsgi. environment variables, one of which is wsgi.input. Django's own test client demonstrates the minimum required set.

Closing this invalid, on the basis that it appears to be a problem in the django-page-cms test framework. If you can provide evidence to the contrary, feel free to reopen.
