Remove deprecated wikibase config variables from configurations
Closed, ResolvedPublic1 Estimate Story Points



The result of this is any site using the sole config variable $wgMFUseWikibaseDescription = true from before June 27th to show taglines who upgrades will now lose their tagline unless they turn on $wgMFDisplayWikibaseDescriptions immediately.

Find where $wgMFUseWikibaseDescription is still used and add the new config $wgMFDisplayWikibaseDescriptions = [ 'tagline' => true ].

Remove the old variables after the changes in T138788 roll out (21st of July).


  • Wikis with old configuration variables and wikibase descriptions enabled keep the descriptions enabled as the config changes/deprecations take effect in rollout
  • Old configuration variables are removed and configuration is up to date and lean
  • The fallback deprecated config variables should remain in MobileFrontend to allow time for 3rd parties to catch up

@dr0ptp4kt I've pulled this in as it is a followup from last sprint 76 and sensitive to the train schedule.

Needs priority and estimation.

^ Looks like cookie licking to me…

What seems to be the problem, officer @phuedx? I've checked the mediawiki-config repo for old config variables and didn't find any.

@bmansurov: You're now fully responsible for signing off this task! Congratulations!

@dr0ptp4kt Can you clarify if you needed one dev to signoff on this, or all 4 that were @-mentioned?

Just one will do.

The task is done although the related task T141067 is being worked on. Since this task is about removing deprecated config vars I call it done.
