Deglobalization

Globals need to die. When everything in MediaWiki is class-based, globals break a lot of the time. This is a list of all the biggest violaters of the "no-globals" style.

At large

• All configuration variables — Replace with new Conf class (harder than it looks: Requests for comment/Configuration database)
• wgConf — Kill it with fire (and replace with new Conf class)
• wgPageProps — Replace with PageProps class
• wgTitle — Use the proper newFrom* functions; Various instances of classes like OutputPage and Article you may be working with will have their own getTitle() that should be used
• wgLang — Replace with User::getLang()

Disputed

These are argued to only be hiding the problem, not solving it. They should be considered either way.

• wgUser — Replace with User::current().
• wgOut — Ideally, replace with a proper output system

Now fixed

• wgArticle — Use the proper newFrom* functions. Deprecated in r88588, removed from 1.20 in r111168.
• wgHooks — Hooks class (since r80435)
