    In openerp It will first clean the leave intervals, to have an ordered list of not-overlapping intervals and initiate the current interval to be the base interval then before finishing skip the current interval and go to next beginning after the current interval: skip and get out of the loop because we are outside range. Use this code in your own module in .py file,

    def remove_leaves(self, cr, uid, interval, leave_intervals, context=None):         
            if not interval:
                return interval
            if leave_intervals is None:
                leave_intervals = []
            intervals = []
            leave_intervals = self.interval_clean(leave_intervals)
            current_interval = [interval[0], interval[1]]
            for leave in leave_intervals:
                if leave[1] <= current_interval[0]:
                if leave[0] >= current_interval[1]:
                if current_interval[0] < leave[0] < current_interval[1]:
                    current_interval[1] = leave[0]
                    intervals.append((current_interval[0], current_interval[1]))
                    current_interval = [leave[1], interval[1]]
                # if current_interval[0] <= leave[1] <= current_interval[1]:
                if current_interval[0] <= leave[1]:
                    current_interval[0] = leave[1]
            if current_interval and current_interval[0] < interval[1]:  
                intervals.append((current_interval[0], current_interval[1]))
            return intervals
