# Ignored users for reviews

Automated test environments may inadvertently participate in code reviews if they copy user-generated change descriptions. For example, if an automated system copied a change description containing #review and subsequently shelved or committed files, a new review would be started. Similarly copying a description with `#review-123` could inadvertently update an existing review. As test environments may involve thousands or millions of tests, such interactions can potentially generate far too many P4 Code Review notifications.

To mitigate this problem, P4 Code Review can be configured to ignore specified users for the purposes of starting or updating a review. Edit the `SWARM_ROOT/data/config.php` file, and provide the list of users to ignore in the `ignored_users` item in the reviews configuration block.

If you make a configuration change, P4 Code Review will not use it until the configuration cache has been reloaded, this forces P4 Code Review to use the new configuration.

You must be an admin or super user to reload the P4 Code Review config cache. Navigate to the User id dropdown menu, select System Information, click the Cache Info tab, and click the Reload Configuration button.

Edit the `SWARM_ROOT/data/config.php` file, and provide the list of users to ignore in the `ignored_users` item in the reviews configuration block. For example:

    <?php
        // this block should be a peer of 'p4'
        'reviews' => array(
            'ignored_users'  => array('build_user1', 'build_user2'),
        ),
