Re: [GMG-Devel] Fixed the apache config example in the wiki

[Christopher Allan Webber]

Apparently by "I fixed things" I should have said "actually I completely
and totally broke them."

But the example on the wiki for fcgid does not work, it appears.  At the
very least, I tested on a friend's server with the following:

  /mgoblin_media/media_entries/nonexistant/

I get:

  The resource could not be found.
  The resource at http://DOMAIN.org/mgoblin_media/media_entries/nonexistant/ 
could not be found
  WSGI Server

This suggests it's being routed through paste/python, which it shouldn't
have to do... it should go through apache!

However, admittedly I tend to get really confused by apache config options.

It does look like everything is being forced through mg.fcgi though.  I'm
not really sure what the right solution is. :\

Basically this:
  RewriteEngine On
  RewriteRule ^(mgoblin_static|mgoblin_media)($|/) - [L]
  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteRule ^/(.*)$ /mg.fcgi/$1 [QSA,L]

*should* be more like:

  RewriteCond %{REQUEST_URI} !^/(mgoblin_static|mgoblin_media)/
  RewriteRule ^/(.*)$ /mg.fcgi/$1 [QSA,L]

... I think.  However, that doesn't work either, for entirely different
reasons: it seems like the aliases to /mgoblin_static/ and
/mgoblin_media/ are not working.

Additionally, the wiki says:

  <Directory /mgoblin_static>
    Order allow,deny
    Allow from all
  </Directory>

  <Directory /mgoblin_media>
    Order allow,deny
    Allow from all
  </Directory>

Shouldn't that be Location, not Directory?

Does someone with better apache/fcgid chops have any idea how to resolve
this? :)

Additionally, I came up with an alternative recipe:

<VirtualHost *:80>
  Options +ExecCGI

  ServerName mediagoblin.example.org
  
  Alias /mgoblin_static/ /srv/mediagoblin/mediagoblin/static/
  Alias /mgoblin_media/ /srv/mediagoblin/user_dev/media/public/
  
  Alias /mgoblin.fcgi /srv/mediagoblin/mg.fcgi
  
  # Rewrite all URLs to fcgi, except for static and media urls                  
                 
  RewriteEngine On
  RewriteCond %{REQUEST_URI} !^/(mgoblin_static|mgoblin_media)/
  RewriteRule ^/(.*)$ /mgoblin.fcgi/$1 [PT,L]
  
  FcgidMaxRequestLen 16777216
  
</VirtualHost>

This works, but the problem with this though is that it ends up
generating urls like:

  /mgoblin.fcgi/u/cwebber/

instead of:

  /u/cwebber/

I think this is related to our supporting of mounting mediagoblin at
subdirectories.  It might also have something to do with SCRIPT_NAME,
which is something that always confuses me on how to do right.

Thoughts?????
