Debugging is an important task to identify the defects in the software. Especially, logging is an important feature of a software system to record runtime information. Detailed logging allows developers to collect run-time information when they ...

• Effectiveness evaluation of near-omniscient debugging with 831 actual bugs.
• Keeping the majority of infected states.
• Predictable trace size from the number of methods.
• Reducing execution time significantly when all tests are ...

One of the important purposes of code review is to find potential defects caused by other developers' code changes. When reviewing bug fixes, it is important to check the program behavior is properly changed to remove the bug. On the other hand, it is ...

Modern code review is a common practice used by software developers to ensure high software quality in open source and industrial projects. During code review, developers submit their code changes which should be reviewed, via tool-based code review ...

Software developers can reduce the implementation cost by calling already provided functions through accessing library Application Programming Interface (API). APIs are often used in combination but how to combine them are not well-documented. Existing ...

"Extract Method" refactoring is commonly used for merging code clones into a single new method. In this position paper, we propose a proactive clone recommendation system for "Extract Method" refactoring. The proposed system that has been implemented as ...

Logging is an important feature for a software system to record its run-time information. Although detailed logs are helpful to identify the cause of a failure in a program execution, constantly recording detailed logs of a long-running system is ...

Understanding the evolution of code clones is important in software maintenance. With the information about how code clones evolve, both developers and researchers can understand the impacts of code clones and build a more robust code clone management ...

Technical question and answer Q&A platforms, such as Stack Overflow, provide a platform for users to ask and answer questions about a wide variety of programming topics. These platforms accumulate a large amount of knowledge, including hundreds of ...

A key success of a Web service is to appropriately design its interface to make it easy to consume and understand. In the context of service-oriented computing (SOC), the service’s interface is the main source of interaction with the consumers to reuse ...

We have been doing code clone analysis with industry collaborators for a long time, and have been always asked a question, "OK, I understand my system contains a lot of code clones, but how slim will it be after merging redundant code clones?" As a ...

Modern code reviews improve the quality of software products. Although modern code reviews rely heavily on human interactions, little is known regarding whether they are performed fairly. Fairness plays a role in any process where decisions that affect ...

Third-party library reuse has become common practice in contemporary software development, as it includes several benefits for developers. Library dependencies are constantly evolving, with newly added features and patches that fix bugs in older ...

ContextRefactoring is recognized as an effective practice to maintain evolving software systems. For software libraries, we study how library developers refactor their Application Programming Interfaces (APIs), especially when it impacts client users by ...

Free and open source software (FOSS) plays an important role in source code reuse practice. They usually come with one or more software licenses written in the header part of source files, stating the requirements and conditions which should be followed ...

Clone-and-own approach is a natural way of source code reuse for software developers. To assess how known bugs and security vulnerabilities of a cloned component affect an application, developers and security analysts need to identify an original ...

Context: Software library reuse has significantly increased the productivity of software developers, reduced time-to-market and improved software quality and reusability. However, with the growing number of reusable software libraries in code ...

Impure refactoring is defined as a refactoring operation that was saved together with non-refactoring changes or several refactoring operations were saved at the same location stored in source code repositories. Many of existing approaches are not ...

One of the most widely used techniques to improve the quality of existing software systems is refactoring—the process of improving the design of existing code by changing its internal structure without altering its external behavior. While it is ...

A software product is often dependent on a large number of third-party components. To assess potential risks, such as security vulnerabilities and license violations, a list of components and their versions in a product is important for release ...

Service-Oriented Architecture (SOA) is an emerging paradigm that has radically changed the way software applications are architected, designed and implemented. SOA allows developers to structure their systems as a set of ready-made, reusable and ...
