indico_wsgi_handler missing from Indico 1.2

[pfurness]

Indico 1.2 doesn't have indico_wsgi_handler packaged with it, but it is apparently required to run Indico.

I have tried an upgrade from 1.1.2 to 1.2. The upgrade ran ok, and the database update ran ok, but when attempting to connect with web browser I get "Internal Server Error"

The apache error log reports as follows:

[Thu Jul 17 13:41:17.537618 2014] [:error] [pid 4785] [remote 194.81.218.26:27693]   File "/opt/indico/htdocs/index.wsgi", line 25, in <module>

Searching on my file system, I find the indico_wsgi_handler module present in previous versions of Indico:

[root@indicodev htdocs]# locate indico_wsgi_handler
/usr/lib/python2.7/site-packages/indico-1.0-py2.7.egg/indico/web/wsgi/indico_wsgi_handler.py

[root@indicodev htdocs]#

To confirm this, I deleted all indico eggs from the server, and then did a fresh install of indico 1.2. I searched again for indico_wsgi_handler and it now is not anywhere on the system.

To me, it looks like it may be a packaging error?

The whole indico.web.wsgi package is gone in 1.2 since we replaced it with a proper framework (flask).

The new WSGI file to point your webserver to is indico/web/indico.wsgi which is also installed as a symlink to the htdocs folder.

Ah, right, I get it. It was not obvious that the change was so significant from the documentation on the wiki.

So, in that case, the upgrade /installation documentation really needs changing as it's wrong! If you follow the instructions, exactly as written, it does not work because many things change including apache config.
I don't have edit rights to the documentation page yet, although I'm happy to update the documentation as soon as I do.

Guess this ticket can be closed - just another user panicking because something doesn't look as expected! :-)

Fixed in the documentation :)

Thanks!
