Basically the same code has been copied and pasted in three places:

    final protected function getScopedPHPBehaviorForCommit() {
        if ( PHP_SAPI != 'cli' ) { // https://bugs.php.net/bug.php?id=47540
            $old = ignore_user_abort( true ); // avoid half-finished operations
            return new ScopedCallback( function () use ( $old ) {
                ignore_user_abort( $old );
            } );
        }

        return null;
    }

• FileBackend::getScopedPHPBehaviorForOps()
• LBFactory::getScopedPHPBehaviorForCommit()
• LoadBalancer::getScopedPHPBehaviorForCommit()

Let's just have it in one place, maybe it can go in the ScopedCallback library?

You are expected to provide two patches in Wikimedia Gerrit: You'll need to introduce a newScopedIgnoreUserAbort function with the above code for the ScopedCallback library (mediawiki/libs/ScopedCallback repository in Gerrit). Then submit a second patch to the above places in MediaWiki core to use your new function.

See https://www.mediawiki.org/wiki/Gerrit/Tutorial for how to set up Git and Gerrit.
