Goals

• Implementation of Requests for comment/Drop actions in favour of page views and special pages
• The creation of a new PageView system.
  • Instead of an Article instance a PageView instance controls what is output into a page including &oldid= handling
  • SpecialPages become PageView implementations
• Removal of the Action system
  • Implementation of actions as special pages
  • Implementation of a layer that lets us use &action= urls for title (and maybe user?) targeted special pages like history, edit, whatlinkshere, and maybe block.
• Removal of functional logic from SkinTemplate
  • Generation of page tabs becomes the job of PageView instead of code hardcoded into SkinTemplate.
  • Likewise for links such as contribs links from a userpage.

Plans

• Start implementing PageView by migrating things piece by piece from Article. - Partially done
• Implement a new SpecialPage interface for action like special pages
  • SpecialPage name autodetection from class name. - Done (@todo Perhaps we should add a test to ensure that 'SpecialPage' doesn't make it think the name is 'Page')
  • Targetable special pages - Partially done
    • target() and executeWithTarget() - Done
    • Type sensitive target() - Done
    • Default executeWithoutTarget() form.
  • A way to mark special pages as ones that should use &action= urls
• Implement actions as special pages
  • Actions within Article
    • Delete
    • Protect
    • Unprotect
    • Render
      • Should we implement Special:Render in a way such that Special:Render/Special:Version works?
  • Actions with their own custom class
    • Raw
    • Edit
      • Find some way to deal with &action=submit
    • History - Partially done
  • Action class based actions
• Implement SpecialPage as a PageView.
• Implement tab handling inside PageView
• Implement canonical url handling inside PageView
• $wgSpecialPageAliases
• ...
• Look over what extensions do with Article and other things that are broken, implement compatibility layers for that functionality and find a way to allow extensions to transition to the new patterns.
