User:Lucas Werkmeister (WMDE)/site ID investigation

From mediawiki.org

Result of investigating Wikibase behavior when site IDs change.

The main example of a changed site ID that we have is Вікіпэдыя беларуская (тарашкевіца), or Wikipedia in Belarusian (Taraškievica orthography), whose language code used to be be-x-old but is now be-tarask. Its database name remains be_x_oldwiki to this day, but it is now hosted on https://be-tarask.wikipedia.org/.

Behavior of Wikibase (and MediaWiki) with regards to that site, as of January 2021:

  • Special pages
    • SetSitelink: accepts be_x_oldwiki; does not accept be-x-old, be_taraskwiki, be-tarask.wikipedia.org
    • ItemByTitle: accepts be_x_oldwiki; does not accept be-x-old, be_taraskwiki, neither in URL nor in site selector/dropdown
    • GoToLinkedPage: accepts be_x_oldwiki; does not accept be-x-old, be_taraskwiki (and this one has no fancy site selector/dropdown, just a text input)
    • NewItem (?site=&page=): accepts be_x_oldwiki; does not accept be-x-old, be_taraskwiki (and in this one the site input is not even editable, so when it’s not recognized, the special page gives you an error on a readonly input field)
  • APIs
    • wbgetentities
      • returned data, sitelinks: uses be_x_oldwiki, site: be_x_oldwiki, url: https://be-tarask.wikipedia.org/wiki/...
      • sites=&titles= parameters: accepts be_x_oldwiki; does not accept be_taraskwiki, be-x-old, be-x-old.wikipedia.org, be-tarask.wikipedia.org
    • wbsetsitelink (linksite=): accepts be_x_oldwiki; does not accept be_taraskwiki, be-x-old, be-x-old.wikipedia.org, be-tarask.wikipedia.org
    • query, prop=langlinks
      • returned data: uses lang be-x-old, url https://be-tarask.wikipedia.org/wiki/...
      • lllang parameter: accepts be-x-old; does not accept be-tarask, be_x_old, be_x_oldwiki (it’s not reported as an error, there are just no results)
    • sitematrix: two entries
      • code: be-tarask, site: []
      • code: be-x-old, site: [ { url: https://be-tarask.wikipedia.org, dbname: be_x_oldwiki } ]
    • query, meta=siteinfo, siprop=interwikimap: two entries
      • prefix: be-tarask, url: https://be-tarask.wikipedia.org/wiki/$1
      • prefix: be-x-old, url: https://be-tarask.wikipedia.org/wiki/$1
  • interactive UIs
    • repo (item) sitelink editing: accepts be_x_oldwiki, be_tarask.wikipedia.org, be-tarask.wikipedia.org, and prefixes thereof (all converted to be_x_oldwiki upon selection); does not accept be-x-old, be_taraskwiki
    • client sitelink creation: accepts be_x_oldwiki, be_tarask.wikipedia.org, be-tarask.wikipedia.org, and prefixes thereof (all converted to be_x_oldwiki upon selection); does not accept be-x-old, be_taraskwiki
  • Lua
    • mw.wikibase.getEntity returned data, sitelinks: contains be_x_oldwiki and nothing else
    • mw.wikibase.getSitelink: returns data for be_x_oldwiki and nothing else
    • entity:getSitelink: returns data for be_x_oldwiki and nothing else
    • mw.wikibase.getEntityIdForTitle: accepts be_x_oldwiki; does not accept be_taraskwiki, be-x-old, be-x-old.wikipedia.org, be-tarask.wikipedia.org
    • mw.site.interwikiMap: contains be-tarask and be-x-old (like siprop=interwikimap above)
    • I found no equivalent of prop=langlinks
