- One problem with the site since the deployment was a problem with our job queue, which meant that emails that were supposed to be sent from the site weren’t. This backlog was removed last night, and a lot of pent-up email was sent.
- There were some HTML cache invalidations that caused parts of the site to get overloaded for a few minutes.
- Yesterday, we started the deployment of the category sorting improvements. We deployed some modifications to the database today. This resulted in a few hiccups on the site that we’ve since mostly recovered from.
One key set of improvements in the MediaWiki 1.17 release is the category sorting work spearheaded by Aryeh Gregor. This code will eventually improve the sorting of categories in different languages, allowing us to choose the most appropriate sort order for the language. For now, we’re at least switching over to a more sensible sorting algorithm (Unicode Collation Algorithm (UCA)), and have made other improvements to sorting.
This set of changes required a modification of the database that we didn’t believe was risky, but was irreversible. Given how complicated the initial 1.17 deployment was, we decided to hold back on deploying this work.
There are still some maintenance scripts left to run before this work is fully-deployed, but most parts of this are done.
