Member Function Documentation

◆ checkCache()

MediaWiki\Storage\PageEditStash::checkCache ( Title  $title,
Content  $content,
User  $user 
)

Check that a prepared edit is in cache and still up-to-date.

This method blocks if the prepared edit is already being rendered, waiting until rendering finishes before doing final validity checks.

The cache is rejected if template or file changes are detected. Note that foreign template or file transclusions are not checked.

This returns an object with the following fields:

  • pstContent: the Content after pre-save-transform
  • output: the ParserOutput instance
  • timestamp: the timestamp of the parse
  • edits: author edit count if they are logged in or NULL otherwise
Parameters
Title$title
Content$content
User$userUser to get parser options from
Returns
stdClass|bool Returns edit stash object or false on cache miss
