In Proceedings of the 42nd International Conference on Software Engineering (ICSE), 2020

Abstract: We present PRECFIX, a pragmatic approach targeting large-scale industrial codebase and making recommendations based on previously observed debugging activities. PRECFIX collects defect-patch pairs from development histories, performs clustering, and extracts generic reusable patching patterns as recommendations. Our approach is able to make recommendations within milliseconds and achieves a false positive rate of 22%. PRECFIX has been rolled out to Alibaba to support various critical businesses.
