Description Milan Kerslager 2013-04-01 19:24:05 EDT
In moodle-2.2.7-1.el6.noarch I was hit by bug which prevent running Moodle web interface with "Cannot redeclare class dml_exception" error.

PHP Fatal error:  require_once(): Cannot redeclare class dml_exception in /var/www/moodle/web/lib/setup.php on line 449

The solution is to use moodle-2.2.9-1.el6.noarch from testing repo by (and then run upgrade process in Moodle itself):

yum update --enablerepo=epel-testing moodle

If it works for you, please leave karma at https://admin.fedoraproject.org/updates/FEDORA-EPEL-2013-0800/moodle-2.2.9-1.el6 to allow pushing to stable repo.
Comment 1 Milan Kerslager 2013-04-01 20:25:27 EDT
There is at least one missing file in testing moodle update I mentioned above:

lib/pear/HTML/QuickForm/DHTMLRulesTableless.php

So the update should not be recommended for 2.2.9-1.el6 version.

Comment 4 Gwyn Ciesla 2013-07-12 11:44:30 EDT
Does simply copying in DHTMLRulesTableless.php restore functionality?  If not, I'll have to get a bundling exception for this from FPC.
Comment 5 Michael Young 2013-07-12 13:06:24 EDT
Yes, if you return that file (I think you need HTML/QuickForm/Renderer/Tableless.php as well) moodle will do things such as updating. Long term, the right solution is for upstream moodle to update their bundled version of QuickForm which doesn't need these workarounds but putting these files back will get moodle working again in the short term.

Filed: https://tracker.moodle.org/browse/MDL-40644

I'll look into a short-term fix.

Yes I can upgrade to that successfully.
Comment 9 Gwyn Ciesla 2013-07-12 15:27:44 EDT
Excellent, I'll get that right out, as well as fixing this on the Fedora branches.
