Reusable execution replay: execution record and replay for source code reuse
Ameer Armaly, Casey Ferris, Collin McMillan · 2014
A key problem during source code reuse is that, to reuse even a small section of code from a program, a programmer must include a huge amount of dependency source code from elsewhere in the same program. These dependencies are no- toriously large and complex, and many can only be known at runtime. In this paper, we propose execution record/replay as a solution to this problem. We describe a novel reuse technique that allows programmers to reuse functions from a C or C++ program, by recording the execution of the program and selectively modifying how its functions are re- played. We have implemented our technique and evaluated it in a preliminary study in which two programmers used our tool to complete four tasks over four hours.
