Use the advanced-cache.php (or object-cache.php) to get rid of wp-config.php modification

There's also a possibility to get rid of db.php as well by plugging into the advanced-cache.php file, which has the ability to modify the global $table_prefix variable since it gets loaded before wp_set_wpdb_vars();

Thanks @ideag for pointing this possibility out :)

This seems like a very good idea since advanced-cache.php is not used so often.

If someone needs to use advanced-cache.php they could just modify that file to include wp-safe-updates as mercator does in sunrise.php:

// Default mu-plugins directory if you haven't set it
defined( 'WPMU_PLUGIN_DIR' ) or define( 'WPMU_PLUGIN_DIR', WP_CONTENT_DIR . '/mu-plugins' );

// Also load mercator for domain mapping
require WPMU_PLUGIN_DIR . '/mercator/mercator.php';

Upon more investigation advanced-cache.php won't work since we need to enable it via a constant and filter. object-cache.php is a better candidate.

Actually, plugin could modify advanced-cache.php and append it's stuff automatically if it is not there. It's a simple string match.

@ideag no, the problem is we still need to define WP_CACHE in wp-config.php for advanced-cache.php to be loaded.

@anttiviljami yeah, i meant object-cache.php :) But the point about doing automatic check-and-append still stands.

Ah, ok 👍 Yes, definitely
