Hello!

I have a question about accessing the internal info of mediawiki in an extension code, e.g. information about revisions for pages. What interface has less chances to change during the development of Media Wiki? Is it database structure or mediawiki classes such as User, Article, Revision?

For example, it's very simple to make select-query for getting all contributors for the page $thisPageTitle:

SELECT rev_user_text FROM page INNER JOIN revision on page.page_id=revision.rev_page WHERE page_title="$thisPageTitle";

On the other hand I'm sure that there exists a class method that allows us to do the same thing.

What of these ways is more proper in terms of portability from one MediaWiki version to another?

Sincerely yours, Yury Katkov
