Changeset 53760 for trunk/src/wp-includes/rest-api/endpoints/class-wp-rest-posts-controller.php

Message:

REST API: Avoid unnecessarily preparing item links.

Do not call the prepare_links methods in core REST API controllers, unless the _links or _embedded fields are requested. There is no need to prepare links if they are never returned in the response. This saves resources, as many calls to prepare_links methods perform database queries.

Props Spacedmonkey, timothyblynjacobs, rachelbaker, desrosj, dlh, hellofromTonya.
Fixes #52992.
