EditPage uses a ton of global objects ($wgOut, $wgUser, etc.). These should be replaced with the appropriate RequestContext function instead.
A getContext() function and $this->context member variable were added in rMW841c4076574b: EditPage: Add getContext() function.
Then, four commits were made to switch global objects out for context equivalents (1000 line chunks):
- rMWf2f810181aa4: EditPage: Use context instead of globals (1/4)
- rMWafa630749a39: EditPage: Use context instead of globals (2/4)
- rMW27fd11095213: EditPage: Use context instead of globals (3/4)
- rMW589cadedf317: EditPage: Use context instead of globals (4/4)
These were reverted in rMW5ce43a986133: Revert serie of "EditPage: Use context instead of globals" due to breakage in LiquidThreads: T143889: Replies impossible: The content format json is not supported by the content model.
We need to check other Wikimedia-deployed extensions and then re-apply the de-globalization change.
