Deploy page previews for anons on dewiki
Closed, ResolvedPublic3 Estimated Story Points

Description

Background

Community consultation: https://de.wikipedia.org/wiki/Wikipedia:Fragen_zur_Wikipedia#Seitenvorschaubilder_(Page_Previews). Results preferred on for anons and new accounts. The changes for new accounts will be tracked under T191888: Change page previews configuration for opt-in accounts. Based on consultation, we should deploy the second change sometime between now and the end of May.

Developer notes

The deploy script should take care of the following

  • wgPopupsAnonsExperimentalGroupSize should be set to 0 for all wikis ('default'). Counter-intuitively this means Popups is enabled to 100% of anons. Note given the value of wmgUsePopups this will not enable Popups for non-wikipedias

During deploy

  • Verify that Page previews is showing on all wikipedias for anonymous users and for logged in (only if opted in) - I suggest testing Spanish, German, Hebrew. Be careful to test anonymous behaviour in an incognito window as you may have previously been opted in via the footer)
  • Verify that the rate of events for VirtualPageViews is still at healthy values (estimated average: ~700-800 events/sec; may be above or below that depending on time of day and day of week). Errors are around normal rate.
  • Verify that page previews remains disabled on all other projects e.g. Wikidata, Wiktionary, English Wikipedia
  • Green light from @ABorbaWMF to sync - QA done by @ovasileva
  • Green light from @Nirzar to sync - QA done by @alexhollender
  • Green light from @ovasileva to sync

this looks like it can be resolved.

All done here :) Noting that we'll track event rates in T189906: Roll out VirtualPageViews to all Wikipedia wikis. Good job everyone!
