Description of problem:
After yum install mediawiki and enabling the *global* aliases in /etc/httpd/conf.d/mediawiki.conf (Not using mw-crateinstance): When visiting http://localhost/wiki, The initial page shows a link to complete the web-based installation. However: Following this link just returns an empty page. The httpd error log shows the following:

I'm not sure why you created a bug report since you are not using the install script.

The package does not automatically create files in /var/www/wiki if you do not use the scripts. If you had any there then it is your responsibility.

Comment 2 Fritz Elfert 2013-05-28 21:08:56 UTC
1. It definitely *does* create /var/www/wiki with some contents.

2. Quote from the installed /etc/httpd/conf.d/mediawiki.conf:

# This is a sample configuration for a wiki instance located under
# /var/www/wiki and exposed as http://thishost/wiki. Please read
# /usr/share/doc/mediawiki-*/README.RPM on whether to use this
# instance or create copies of it.

So this suggests that the install-script is optional! (Only required if one wants to create multiple instances instead of using the predefined one located at /var/www/wiki

I suggest you fix this comment or create a README.Fedora wher ist clearly states that the predefinded thingy mentioned above is *not* suppoerted.

Comment 3 Fritz Elfert 2013-05-30 15:13:46 UTC
After some thorough testing on a FRESHLY F18 VM:

This is simply not true! See the following proof:

# rpm -V mediawiki
(no output, so nothing modified)
# rpm -qf /var/www/wiki
mediawiki-1.19.6-1.fc18.noarch
# rpm -qf /etc/mediawiki/instances
mediawiki-1.19.6-1.fc18.noarch
# cat /etc/mediawiki/instances
/var/www/wiki
# rpm -q --scripts mediawiki
postinstall scriptlet (using /bin/sh):
/usr/sbin/mw-updateallinstances >> /var/log/mediawiki-updates.log 2>&1 || :

# sh -x /usr/sbin/mw-updateallinstances
+ read path
+ cat /etc/mediawiki/instances
+ grep '^ *#'
+ echo /var/www/wiki
+ mw-createinstance /var/www/wiki
+ test -e /var/www/wiki/LocalSettings.php
+ read path

q.e.d.

The actual bug is in mw-createinstance in the for-loop starting at line 26,
which misses several names for which symlinks should be created.

Comment 4 Fritz Elfert 2013-05-30 15:20:54 UTC
Another comment on your closing comment:

Since the actual bug is in mw-createinstance it would have given the exact same result if i had used that script in the first place. No matter how the package is installed - it does not work at all without tweaking the file hierarchy manually.
