That task is crucial in reducing time and efforts in a bug fixing process. In this paper, we propose Bugzie, a novel approach for automatic bug triaging based on fuzzy set and cache-based modeling of the bug-fixing expertise of developers. Bugzie considers a software system to have multiple technical aspects, each of which is associated with technical terms. For each technical term, it uses a fuzzy set to represent the developers who are capable/competent of fixing the bugs relevant to the corresponding aspect. The fixing correlation of a developer toward a technical term is represented by his/her membership score toward the corresponding fuzzy set. The score is calculated based on the bug reports that (s)he has fixed, and is updated as the newly fixed bug reports are available. For a new bug report, Bugzie combines the fuzzy sets corresponding to its terms and ranks the developers based on their membership scores toward that combined fuzzy set to find the most capable fixers. Our empirical results show that Bugzie achieves significantly higher accuracy and time efficiency than existing state-of-the-art approaches.","PeriodicalId":184518,"journal":{"name":"ESEC/FSE '11","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125037617","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cifuentes, Nathan Keynes","doi":"10.1145/2025113.2025160","DOIUrl":"https://doi.org/10.1145/2025113.2025160","url":null,"abstract":"Points-to analysis is a fundamental static analysis technique which computes the set of memory objects that a pointer may point to. Many different applications, such as security-related program analyses, bug checking, and analyses of multi-threaded programs, require precise points-to information to be effective. Recent work has focused on improving the precision of points-to analysis through flow-sensitivity and great progress has been made. However, even with all recent progress, flow-sensitive points-to analysis can still be much slower than a flow-insensitive analysis.\u0000 In this paper, we propose a novel method that simplifies flow-sensitive points-to analysis to a general graph reachability problem in a value flow graph. The value flow graph summarizes dependencies between pointer variables, including those memory dependencies via pointer dereferences. The points-to set for each pointer variable can then be computed as the set of memory objects that can reach it in the graph. We develop an algorithm to build the value flow graph efficiently by examining the pointed-to-by set of a memory object, i.e., the set of pointers that point to an object. The pointed-to-by information of memory objects is very useful for applications such as escape analysis, and information flow analysis.\u0000 Our approach is intuitive, easy to implement and very efficient. The implementation is around 2000 lines of code and it is more efficient than existing flow-sensitive points-to analyses. The runtime is comparable with the state-of-the-art flow-insensitive points-to analysis.","PeriodicalId":184518,"journal":{"name":"ESEC/FSE '11","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116222132","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, to date these predictions have a limited adoption in practice. The most commonly cited reason is that the prediction identifies too much code to review without distinguishing the impact of these defects. Our aim is to address this drawback by focusing on high-impact defects for customers and practitioners. Customers are highly impacted by defects that break pre-existing functionality (breakage defects), whereas practitioners are caught off-guard by defects in files that had relatively few pre-release changes (surprise defects). The large commercial software system that we study already had an established concept of breakages as the highest-impact defects, however, the concept of surprises is novel and not as well established. We find that surprise defects are related to incomplete requirements and that the common assumption that a fix is caused by a previous change does not hold in this project. We then fit prediction models that are effective at identifying files containing breakages and surprises. The number of pre-release defects and file size are good indicators of breakages, whereas the number of co-changed files and the amount of time between the latest pre-release change and the release date are good indicators of surprises. Although our prediction models are effective at identifying files that have breakages and surprises, we learn that the prediction should also identify the nature or type of defects, with each type being specific enough to be easily identified and repaired.","PeriodicalId":184518,"journal":{"name":"ESEC/FSE '11","volume":"430 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132452931","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
