Commit credit
When you use P4 Code Review to commit a review, but you are not the review's author, P4 Code Review gives credit to the review author by default. Activity stream entries and email notifications include both the committer and review author's details.
If changes to the config.php file might have caused the P4 Code Review web interface to become unresponsive, remove the problematic changes from the config.php file, then clear the configuration cache by running this command:rm -f /opt/perforce/swarm/data/cache/module-config-cache.php
If you prefer P4 Code Review's original behavior, which was to give credit only to the committer, you can do so by editing the SWARM_ROOT/data/config.php file and setting the commit_credit_author item to false in the reviews configuration block. For example:
<?php
// this block should be a peer of 'p4'
'reviews' => array(
'commit_credit_author' => false,
),
