PASTA: Synthesizing Object State Transformers for Dynamic Software Updates

Zelin Zhao, Yanyan Jiang, Chang Xu, Tianxiao Gu, Xiaoxing Ma

Abstract: Object transformation (upgrading heap objects to their new-version counterparts) is a crucial step in dynamic software update (DSU). However, providing non-trivial object transformers for complex software updates can be difficult for software developers and upgrade maintainers. This paper presents the design and implementation of PASTA, a tool for automatic object transformer synthesis.
