AutoSQL: Extracting SQL Templates from Imperative ORM Code in Large-Scale Repositories
Junsong Pu, Yichen Li, Zhuangbin Chen +2
Suboptimal SQL queries can significantly degrade the performance of cloud systems, motivating the extraction and auditing of SQL statements before deployment. However, Go ORM frame…
LogNLQ: Natural-Language Log Querying with Parser-Induced and Semantically Grounded Schemas
Juepeng Wang, Jinyang Liu, Zhuangbin Chen +1
Logs are essential for system monitoring and failure diagnoses in modern software systems, yet querying them through natural language remains an open challenge. Existing approaches…
MASPrism: Lightweight Failure Attribution for Multi-Agent Systems Using Prefill-Stage Signals
Yang Liu, Hongjiang Feng, Junsong Pu +1
Failure attribution in LLM-based multi-agent systems aims to identify the steps that contribute to a failed execution. This task remains difficult because a single execution can co…
TypeScript Repository Indexing for Code Agent Retrieval
Junsong Pu, Yichen Li, Zhuangbin Chen
Graph-based code indexing can improve context retrieval for LLM-based code agents by preserving call chains and dependency relationships that keyword search and similarity retrieva…
MAS-FIRE: Fault Injection and Reliability Evaluation for LLM-Based Multi-Agent Systems
Jin Jia, Zhiling Deng, Zhuangbin Chen +2
As LLM-based Multi-Agent Systems (MAS) are increasingly deployed for complex tasks, ensuring their reliability has become a pressing challenge. Since MAS coordinate through unstruc…
LogPrism: Unifying Structure and Variable Encoding for Effective Log Compression
Yang Liu, Kaiming Zhang, Zhuangbin Chen +1
In the field of log compression, the prevailing "parse-then-compress" paradigm fundamentally limits effectiveness by treating log parsing and compression as isolated objectives. Wh…
Cast: Automated Resilience Testing for Production Cloud Service Systems
Zhuangbin Chen, Zhiling Deng, Kaiming Zhang +4
The distributed nature of microservice architecture introduces significant resilience challenges. Traditional testing methods, limited by extensive manual effort and oversimplified…
MicroRacer: Detecting Concurrency Bugs for Cloud Service Systems
Zhiling Deng, Juepeng Wang, Zhuangbin Chen
Modern cloud applications delivering global services are often built on distributed systems with a microservice architecture. In such systems, end-to-end user requests traverse mul…
Metronome: Differentiated Delay Scheduling for Serverless Functions
Zhuangbin Chen, Juzheng Zheng, Zibin Zheng
Function-as-a-Service (FaaS) computing is an emerging cloud computing paradigm for its ease-of-management and elasticity. However, optimizing scheduling for serverless functions re…
ErrorPrism: Reconstructing Error Propagation Paths in Cloud Service Systems
Junsong Pu, Yichen Li, Zhuangbin Chen +6
Reliability management in cloud service systems is challenging due to the cascading effect of failures. Error wrapping, a practice prevalent in modern microservice development, enr…
An Empirical Study of Interaction Bugs in ROS-based Software
Zhixiang Chen, Zhuangbin Chen, Xingjie Cai +2
Modern robotic systems integrate multiple independent software and hardware components, each responsible for distinct functionalities such as perception, decision-making, and execu…
Tracezip: Efficient Distributed Tracing via Trace Compression
Zhuangbin Chen, Junsong Pu, Zibin Zheng
Distributed tracing serves as a fundamental building block in the monitoring and testing of cloud service systems. To reduce computational and storage overheads, the de facto pract…
