Changeset 43087 for trunk/src/wp-includes/rest-api/endpoints/class-wp-rest-post-types-controller.php

Message:

REST API: Filter responses based on the _fields parameter, before data is processed.

Historically, the REST API would generate the entire response object, including running expensive filters, then it would apply the _fields parameter, discarding the fields that weren't specificed.

This change causes _fields to be applied earlier, so that only requested fields are processed.

Props danielbachhuber.
