Changeset 54771 for trunk/src/wp-includes/post.php

Message:

Query: Prevent ID only queries erroring when starting the loop.

Ensure only full post objects are passed to update_post_author_caches() when called within WP_Query::the_post(). This prevents an error when starting the Loop for Queries initiated with a subset of fields or IDs only.

Props konyoldeath, dd32, lozula, TimothyBlynJacobs, spacedmonkey, mxbclang, peterwilsoncc.
Fixes #56948.
