if ($this->savepointSupport) {
return parent::rollBack($savepoint_name);
}
if (!$this->inTransaction()) {
throw new TransactionNoActiveException();
}

// in question has already been rolled back.
if (!isset($this->transactionLayers[$savepoint_name])) {
return;
}
// We need to find the point we're rolling back to, all other savepoints
// before are no longer needed.
while ($savepoint = array_pop($this->transactionLayers)) {
if ($savepoint == $savepoint_name) {
// Mark whole stack of transactions as needed roll back.
$this->willRollback = TRUE;
// If it is the last the transaction in the stack, then it is not a
// savepoint, it is the transaction itself so we will need to roll back
// the transaction rather than a savepoint.

break;
