Purge objectcache table during upgrade and installation scripts
Closed, ResolvedPublic

Description

Changes made to the MediaWiki namespace weren't available after updating MediaWiki to version 1.8.2 after runnung
maintenance/update.php.

The pages in MediaWiki namespace where still available with all their content, but neither Special:Allmessages nor
the GUI showed the changes anymore.

After investigating with several updated and a freshly installed wiki with Brion he found out, that the reason was
in the objectcache table.

We therefore agreed to include a purge cache function into maintenance/update.php to avoid this problem in future.

Version: 1.8.x
Severity: enhancement

right now I found out (on two different wikis on two different servers): If you don't clear the object cache after upgrading from 1.8.2 to 1.9alpha apache will start using
up all CPU time.

After clearing the cache it worked smoothly.
