which Configuration Option should i change
International Conference on Software Engineering, 2014Co-Authors: Sai Zhang, Michael D ErnstAbstract:Modern software often exposes Configuration Options that enable users to customize its behavior. During software evolution, developers may change how the Configuration Options behave. When upgrading to a new software version, users may need to re-configure the software by changing the values of certain Configuration Options. This paper addresses the following question during the evolution of a configurable software system: which Configuration Options should a user change to maintain the software's desired behavior? This paper presents a technique (and its tool implementation, called ConfSuggester) to troubleshoot Configuration errors caused by software evolution. ConfSuggester uses dynamic profiling, execution trace comparison, and static analysis to link the undesired behavior to its root cause - a Configuration Option whose value can be changed to produce desired behavior from the new software version. We evaluated ConfSuggester on 8 Configuration errors from 6 configurable software systems written in Java. For 6 errors, the rootcause Configuration Option was ConfSuggester's first suggestion. For 1 error, the root cause was ConfSuggester's third suggestion. The root cause of the remaining error was ConfSuggester's sixth suggestion. Overall, ConfSuggester produced significantly better results than two existing techniques. ConfSuggester runs in just a few minutes, making it an attractive alternative to manual debugging.

ConfDiagnoser: An automated Configuration error diagnosis tool for Java software
2013 35th International Conference on Software Engineering (ICSE), 2013Co-Authors: Sai ZhangAbstract:This paper presents ConfDiagnoser, an automated Configuration error diagnosis tool for Java software. Conf-Diagnoser identifies the root cause of a Configuration error - a single Configuration Option that can be changed to produce desired behavior. It uses static analysis, dynamic profiling, and statistical analysis to link the undesired behavior to specific Configuration Options. ConfDiagnoser differs from existing approaches in two key aspects: it does not require users to provide a testing oracle (to check whether the software functions correctly) and thus is fully-automated; and it can diagnose both crashing and non-crashing errors. We demonstrated ConfDiagnoser's accuracy and speed on 5 non-crashing Configuration errors and 9 crashing Configuration errors from 5 configurable software systems.

Automated diagnosis of software Configuration errors
2013 35th International Conference on Software Engineering (ICSE), 2013Co-Authors: Sai Zhang, Michael D ErnstAbstract:The behavior of a software system often depends on how that system is configured. Small Configuration errors can lead to hard-to-diagnose undesired behaviors. We present a technique (and its tool implementation, called ConfDiagnoser) to identify the root cause of a Configuration error - a single Configuration Option that can be changed to produce desired behavior. Our technique uses static analysis, dynamic profiling, and statistical analysis to link the undesired behavior to specific Configuration Options. It differs from existing approaches in two key aspects: it does not require users to provide a testing oracle (to check whether the software functions correctly) and thus is fully automated; and it can diagnose both crashing and non-crashing errors. We evaluated ConfDiagnoser on 5 non-crashing Configuration errors and 9 crashing Configuration errors from 5 configurable software systems written in Java. On average, the root cause was ConfDiagnoser's fifth-ranked suggestion; in 10 out of 14 errors, the root cause was one of the top 3 suggestions; and more than half of the time, the root cause was the first suggestion.

BigCom - Which Classes Can Be Configured as Beans in Spring XML Files
2019 5th International Conference on Big Data Computing and Communications (BIGCOM), 2019Co-Authors: Xi Wang, Lintao XianAbstract:Automatically extracting software Configuration Options not only dramatically reduces the burden of maintaining Configuration manuals, but also is an essential part of tackling Configuration errors. Existing approaches focus on the key-value Configuration model, and depend heavily on the arguments of Configuration APIs to infer Configuration Option names. However, we find that some software adopts the Spring XML Configuration model whose Configuration Options are the elements and the elements. Specially, these elements are nothing to do with the arguments of Configuration APIs. To address this problem, we describe the Configuration mechanism of the Spring XML Configuration model, and present BeanFinder, a static analysis approach to automatically extracting Configuration Options for software using this model. An empirical evaluation performed on 3 Java open source software shows the effectiveness of BeanFinder.
