In the legacy promotion system, there's a separation of tasks between
order.recalculate
andPromotionHandler::Cart
.order.recalculate
will only recalculate already existing promotion adjustments, but will not check for any new promotions that might need to be applied. In the new promotion system, both of these tasks are handled byorder.recalculate
.If the legacy promotion system is present, but not active, calling this promotion handler will result in a single database call, which is an acceptable price to pay I think.
