Changeset 58128 for trunk/src/wp-includes/load.php

Message:

Upgrade/Install: Automatically roll back to the previous version when an automatic plugin update results in a fatal error on the front end of the site.

This builds on the temporary backup system introduced in 6.3 to allow automatic updates to benefit from fatal error protection. A loopback request is performed to the home page of the site and the plugin is rolled back to its backed up version if a fatal error is observed.

For debugging and observability during beta, this change includes several calls to error_log() during the upgrade and rollback stages. These calls can be removed or placed behind a flag once we're ready for RC1.
