CodeCarbonCopy

Abstract

We present CodeCarbonCopy (CCC), a system for transferring code from a donor application into a recipient application. CCC starts with functionality identified by the developer to transfer into an insertion point (again identified by the developer) in the recipient. CCC uses paired executions of the donor and recipient on the same input file to obtain a translation between the data representation and name space of the recipient and the data representation and name space of the donor. It also implements a static analysis that identifies and removes irrelevant functionality useful in the donor but not in the recipient. We evaluate CCC on eight transfers between six applications. Our results show that CCC can successfully transfer donor functionality into recipient applications.
