DSDSR: a tool that uses dynamic symbolic execution for data structure repair

We present DSDSR, a generic repair tool for complex data structures. Generic, automatic data structure repair algorithms have applications in many areas. Reducing repair time can may therefore have a significant impact on software robustness. Current state of the art tools try to address the problem exhaustively and their performance depend primarily on the style of the correctness condition. We propose a new approach and implement a prototype that suffers less from style limitations and utilizes recent improvements in automatic theorem proving to reduce the time required in repairing a corrupt data structure. We also present experimental results to demonstrate the promise of our approach for generic repair and discuss our prototype implementation.
