Migrate Wikimini into WMCH infrastructure
Closed, ResolvedPublic
Actions

Description

Wikimedia CH is planning to help Wikimini (https://wikimini.org/) in their migration to WMCH infrastructure.

Plan

  • initialize the needed WMCH environment to welcome the new Wikimini's MediaWiki farm (done on server wmch-members2)
  • work on the "Wikimini.org→WMCH" import script (and reduce import time - done from ~4 hours down to ~45 minutes)
  • do a first temporary import
  • put online the new entry point https://wikimini.wikimedia.ch/ - https://sv.wikimini.wikimedia.ch/ ecc.
  • first test period and bug fixes
  • alert https://wikimini.org users about final migration
  • set https://wikimini.org in read-only
  • execute the "Wikimini.org→WMCH" sync again
  • update the DNS records of Wikimini.org
  • set wikimini in write-mode again
  • keep old servers online for a couple of days
  • shutdown old servers
  • dismiss old servers

When

Analyzing the current usage with Matmo, to have a minimal impact, the final migration can be fixed in a Thursday or a Friday, 02:30-04:30 PM CEST.

Intervention report

Currently it seems they have 8 wikis (ar, en, es, fr, it, lab, stock, sv and a test wiki):

I've disabled the Extension:WhosOnline that was causing unuseful overhead. Note that now we have Matomo (T268331).

That extension was also the cause of a couple of exceptions in every page when in read-only mode.

User sessions:

There is still a problem with the user sessions though. While editing an article, users randomly get disconnected and cannot submit its modification. This occurs after a few minutes. Users also get immediately disconnected while switching from a wiki to another (ex: from Wikimini FR to Wikimini Stock).

Less urgent issues:
The picture of the day doesn't work anymore. On both Wikimini FR and Wikimini SV, the pictures and their caption where being automatically generated by two custom coded scripts located in this directory: https://fr.wikimini.org/w/pictures-of-the-day/. As far as I remember, two cron jobs were running these scripts daily. Maybe it's necessary to recreate these cron jobs on the new server and run a CHMOD 777 on the directories where the thumbnails are being saved.

It looks like the WhosOnline Extension was removed. We were using this extension to show the online users on the main page (only to the logged in users) as seen in the attached picture.
I performed a speed test on both the Google Page speed tool and GT Metrics, and unfortunately the results are quite bad (20/100 on Google Page Speed and F Score on GT Metrics). Both tools offer a few suggestions, and within these solutions "Enable text compression" seems to be the one that would have the higher impact. I don´t know how easy that would. On the previous server, we were using xcache as a caching system. I don't know if it's still being used? Once in the past, I also tried to use the caching functionalities of Cloudlfare, but there were some problems on the wiki (recent changes not updating, error 500 on create account page...). This is the reason why we currently use Cloudlfare for DNS only.
Thank you again for your efforts and attention!
