[Wikitech-l] Extension migration: LinksDeletionUpdate is now a subclass of LinksUpdate

Hi there, (https://www.mediawiki.org/wiki/Release_notes/1.33) I have an extension that uses the LinksUpdate hook to re-parse the article in order to extract meta-data that it then stores in the DB for use elsewhere in the extension. I use LinksUpdate, rather than ArticleSaveComplete, as I also need to re-parse the article when any of its templates changes. This hook captures all changes that affect the page (by my understanding) except - up until 1.33 - deletions. I therefore also use the ArticleDeleteComplete hook to remove the article from the extension's meta-data tables when the article is deleted. In the light of the above change to the LinksUpdate hook, what changes do I need to make to my extension? Shall I simply drop the ArticleDeleteComplete hook and update LinksUpdate to check whether an article is deleted or not (how?) to decide which action is required? Or is there more to it. On a separate note, I also reparse the page when the ArticleUndelete hook is called. Is this necessary, or is LinksUpdate also being called for undeletes? Finally, I do a similar thing in the TitleMoveComplete hook - I reparse both the old article and the new article. Is this also redundant due to LinksUpdate calls, or not? Kind regards, - Mark Clements (HappyDog)
