Automatic Patch Generation for IoT Based on Code Clone Detection

Abstract

In IoT development, boilerplate implementations for communication protocols, device operation, and so on are frequently needed. Therefore, similar patches may be applied to other code fragments when a patch is prepared for a particular defect. In this study, given a single patch for a defect, we propose an approach to detect code clones of the defect and generate patches for them. In a case study, we extracted 26 cases from a dataset of IoT defects in which code clones of the defects existed and applied the proposed approach to them. As a result, we found that the proposed approach successfully generated patches for all 26 cases.
