#34395 closed defect (bug) (fixed)

Don't load admin files on each request

Reported by: dimadin's profile dimadin Owned by: wonderboymusic's profile wonderboymusic
Milestone: 4.4 Priority: normal
Severity: normal Version: 4.4
Component: REST API Keywords: has-patch dev-feedback

In wp-settings.php, where WordPress is actually started, we load wp-includes/rest-api.php which loads wp-includes/rest-api/class-wp-rest-server.php which loads wp-admin/includes/admin.php which then loads a bunch of admin files and translation.

This is wrong for two reasons:

  • We shouldn't load admin files on each request.
  • It is against #33413.

I don't see why admin files are needed in WP_REST_Server though they might be needed by REST API. In that case, it should be lazy loaded somewhere.

  • Keywords has-patch dev-feedback added
  • Milestone changed from Awaiting Review to 4.4

This was introduced long time ago, back when @rmccue worked on it during GsoC. See

Seems like it was related to some date handling functions. I ran the core tests and the plugin tests from GitHub now without including wp-admin/includes/admin.php and it worked without a problem. So either it really isn't needed or we just don't know the reason why it's still included.
