SiblingRepair: Sibling-Based Multi-Hunk Repair with Large Language Models
Xinyu Liu, Jiayu Ren, Yusen Wang +3
Developers often make similar mistakes across code locations implementing related functionalities. These locations, called siblings, share similar issues and require similar fixes.…
On the Effectiveness of Context Compression for Repository-Level Tasks: An Empirical Investigation
Jia Feng, Zhanyue Qin, Cuiyun Gao +4
Repository-level code intelligence tasks require large language models (LLMs) to process long, multi-file contexts. Such inputs introduce three challenges: crucial context can be o…
WebMAC: A Multi-Agent Collaborative Framework for Scenario Testing of Web Systems
Zhenyu Wan, Gong Chen, Qing Huang +1
Scenario testing is an important technique for detecting errors in web systems. Testers draft test scenarios and convert them into test scripts for execution. Early methods relied…
Multi-View Adaptive Contrastive Learning for Information Retrieval Based Fault Localization
Chunying Zhou, Xiaoyuan Xie, Gong Chen +2
Most studies focused on information retrieval-based techniques for fault localization, which built representations for bug reports and source code files and matched their semantic…
MT4DP: Data Poisoning Attack Detection for DL-based Code Search Models via Metamorphic Testing
Gong Chen, Wenjie Liu, Xiaoyuan Xie +3
Recently, several studies have indicated that data poisoning attacks pose a severe security threat to deep learning-based (DL-based) code search models. Attackers inject carefully…
IssueCourier: Multi-Relational Heterogeneous Temporal Graph Neural Network for Open-Source Issue Assignment
Chunying Zhou, Xiaoyuan Xie, Gong Chen +2
Issue assignment plays a critical role in open-source software (OSS) maintenance, which involves recommending the most suitable developers to address the reported issues. Given the…
