Description (last modified by Ola)

The following script https://github.com/aleksandra-tarkowska/openmicroscopy/blob/iss_deploy_improvement/components/tools/OmeroPy/src/omero_web_iis.py allowed our Django application being smoothly deployed on Windows IIS 6 or 7 With Django<=1.6. Since we upgraded Django to use 1.8 this no longer works. There is not much in the logfile.

I'm not very happy to keep such bugs open until someone can demonstrate that Django is at fault.

Agree with Claude, this doesn't (yet) look like a problem with Django. The reporter will need to provide additional information. Here's some ideas for collecting more information.

Set DEBUG=True in your settings (make sure it's not in production though!) and try to make the request. You should get the django error page which will give you information about the error and a stacktrace if the error was within the django process.

Additionally, set up logging in your settings to write to a file. Until you can see what is happening within django to cause the error, we can't help you.

This is the error when deploying using the script given above https://github.com/aleksandra-tarkowska/openmicroscopy/blob/iss_deploy_improvement/components/tools/OmeroPy/src/omero_web_iis.py:

> c:\omero.server\lib\python\omero_web_iis.py(133)<module>()->None
-> HandleCommandLine(params)
(Pdb)
Exception AttributeError: "'NoneType' object has no attribute 'path'" in <bound
method Signal._remove_receiver of <django.dispatch.dispatcher.Signal object at 0
x00000000055A4048>> ignored

I am not even getting to the Django page and nothing in the log file when submit the request. Http response says A server error occurred. Please contact the administrator.

Response header:

Connection: close
Content-Length: 59
Content-Type: text/plain
Date: Fri, 20 Nov 2015 12:03:10 GMT
Server: Microsoft-IIS/8.5

X-UA-Compatible: IE=Edge

I can only confirm that 404 technical response is working

Please note that I have no issue with deploying application on Unix using apache and mod_wsgi or nginx and gunicorn. This is just IIS and 1.8 problem

Sorry, but the provided information still doesn't demonstrate to me that Django is at fault (although I never used IIS before and don't have a setup to reproduce there error).

Maybe you get can help from other IIS users using TicketClosingReasons/UseSupportChannels and then reopen this with a better description of why Django is at fault and what change we need to make? It would also be helpful if you could bisect to the Django commit where things stopped working. Thanks!
