Identifying static analysis techniques for finding non-fix hunks in fix revisions

Yungbum Jung, Hakjoo Oh, Kwangkeun Yi
2009 Proceeding of the ACM first international workshop on Data-intensive software management and mining - DSMM '09  
We classified these non-fix hunks into 11 patterns. For all patterns we enumerate enabling static analysis techniques.  ...  Mining software repositories for bug detection requires accurate techniques of identifying bug-fix revisions. There have been many researches to find exact bug-fix revisions.  ...  ACKNOWLEDGMENT We thank Sunghun Kim for his contributions to give us bug-fix revision, their hunks, and many useful comments. We also thank Soonho Kong for his precious comments.  ...

Memories of bug fixes

Sunghun Kim, Kai Pan, E. E. James Whitehead
2006 Proceedings of the 14th ACM SIGSOFT international symposium on Foundations of software engineering - SIGSOFT '06/FSE-14  
Analysis of five open source projects shows that, for these projects, 19.3%-40.3% of bugs appear repeatedly in the memories, and 7.9%-15.5% of bug and fix pairs are found in memories.  ...  Furthermore, for the bug and fix pairs, it is possible to both detect the bug and provide a strong suggestion for the fix.  ...  We especially thank Kevin Greenan and the Storage Systems Research Center at UCSC for allowing the use of their cluster for our research.  ...

Understanding bug fix patterns in verilog

Sangeetha Sudakrishnan, Janaki Madhavan, E. James Whitehead, Jose Renau
2008 Proceedings of the 2008 international workshop on Mining software repositories - MSR '08  
We find that 29 − 55% of the bug fix pattern instances in Verilog involve assignment statements, while 18 − 25% are related to if statements.  ...  In this project, we analyze the bug fix history of four hardware projects written in Verilog and manually define 25 bug fix patterns. The frequency of each bug type is then computed for all projects.  ...  RELATED WORK Bugs in software are difficult to find and costly to fix. Therefore, static code analysis to detect bugs is a very active area of research in software engineering.  ...

Toward an understanding of bug fix patterns

Kai Pan, Sunghun Kim, E. James Whitehead
2008 Empirical Software Engineering  
Defined bug fix patterns cover 45.7% to 63.3% of the total bug fix hunk pairs in these projects. The frequency of occurrence of each bug fix pattern is computed across all projects.  ...  Analysis of if conditional bug fix sub-patterns shows a trend towards increasing conditional complexity in if conditional fixes.  ...  Combining static or dynamic analysis and mining repositories techniques to identify bugs are proposed. Williams and Hollingsworth (2005) use project histories to improve existing bug finding tools.  ...

Automatic Identification of Bug-Introducing Changes

Sunghun Kim, Thomas Zimmermann, Kai Pan, E. Jr. Whitehead
2006 21st IEEE/ACM International Conference on Automated Software Engineering (ASE'06)  
Bug-fixes are widely used for predicting bugs or finding risky parts of software. However, a bug-fix does not contain information about the change that initially introduced a bug.  ...  In this paper, we present algorithms to automatically and accurately identify bug-introducing changes.  ...  To check how many bug-fix hunks are true bug-fixes, we manually verified all bug-fix hunks and marked them as bug-fix or non-bug-fix.  ...

Mining Fix Patterns for FindBugs Violations [article]

Kui Liu, Dongsun Kim, Tegawendé F. Bissyandé, Shin Yoo, Yves Le Traon
2018 arXiv   pre-print
In this paper, we first collect and track a large number of fixed and unfixed violations across revisions of software.  ...  To automatically identify patterns in violations and their fixes, we propose an approach that utilizes convolutional neural networks to learn features and clustering to regroup similar instances.  ...  Static analysis techniques are widely used in modern software projects 32 .  ...

Ownership, experience and defects

Foyzur Rahman, Premkumar Devanbu
2011 Proceeding of the 33rd international conference on Software engineering - ICSE '11  
We find that implicated code is more strongly associated with a single developer's contribution; our findings also indicate that an author's specialized experience in the target file is more important  ...  Using version history, we examine contributions to code fragments that are actually repaired to fix bugs. Are these code fragments "implicated" in bugs the result of contributions from many?  ...  Any opinions, findings, and conclusions or recommendations expressed in this material are those of the authors and do not necessarily reflect the views of the National Science Foundation.  ...

A Closer Look at Real-World Patches

Kui Liu, Dongsun Kim, Anil Koyuncu, Li Li, Tegawende F. Bissyande, Yves Le Traon
2018 2018 IEEE International Conference on Software Maintenance and Evolution (ICSME)  
We find that there are opportunities for APR techniques to improve their effectiveness by looking at code elements that have not yet been investigated.  ...  For example, a small number of statement and expression types are recurrently impacted by real-world patches, and expression-level granularity could reduce search space of finding fix ingredients, where  ...  [24] further reported that most bug fix hunks (91-96%) are small ones and ignoring large hunks has minimal impact on patch analysis.

Dekel Cohen, Amiram Yehudai
2015 arXiv   pre-print
Code changes, such as bug fixes or new feature work, may result in a regression bug.  ...  In over 90% of the cases, the developer only has to examine 10-20 lines of code in order to locate the bug, regardless of the code base size.  ...  Other mitigations, such as Code Reviews, Change classification [5] and Change Impact Analysis using dynamic and static techniques [6] , [7] were also studied.  ...
