Software systems are often subject to unexpected runtime errors. Automatic runtime recovery (ARR) techniques aim to recover them from erroneous states and maintain them functional in the field. This paper proposes Ares, a novel, practical approach for ARR. Our key insight is leveraging a system's inherent error handling support to recover from unexpected errors. To this end, we synthesize error handlers...
Dynamic software updating (DSU) is a technique that can update running software systems without stopping them. Most existing approaches require programmer participation to guarantee the correctness of dynamic updating. However, manually preparing dynamic updating is error-prone and time-consuming. Therefore, other approaches prefer to aggressively perform updating without programmer intervention,...
Dynamic software updating (DSU) aims to patch software for fixing bugs or adding functions while it is running. Before update, developers need to make a dynamic patch ready, which includes update points, state transformers and a corresponding code patch. Existing practice mostly assumes manual preparation of dynamic patches, but this process can be both time-consuming and error-prone. Some pioneer...
