A version control system, such as Git, requires a way to integrate changes from different developers or branches. Given a merge scenario, a merge tool either outputs a clean integration of the changes, or it outputs a conflict for manual resolution. A ...

JavaScript is originally a prototype-based, object-oriented language, but in 2015, ECMAScript 2015 (ES2015) introduced a syntax sugar that enables the class-based programming style. However, the use of the class syntax is not mandatory, and it is not ...

Continuous Integration (CI) is a common practice adopted by modern software organizations. It plays an especially important role for large corporations like Ubisoft, where thousands of build jobs are submitted daily. Indeed, the cadence of development ...

Programmers can make the variables easy to understand by choosing meaningful names. However, even though individual names are meaningful, a collection of them might adversely affect the code readability when their names are highly similar, such as “...

The lack of comprehensive sources of accurate vulnerability data represents a critical obstacle to studying and understanding software vulnerabilities (and their corrections). In this article, we present an approach that combines heuristics stemming from ...

Faced with more than 100M open source projects, a more manageable small subset is needed for most empirical investigations. More than half of the research papers in leading venues investigated filtering projects by some measure of popularity with ...

The incremental build is a key feature of build automation tools. It still plays a key role in the build systems that underpin DevOps pipelines. Yet it is quite common for these "upper layer" automation technologies to start from a clean copy of the ...

Nowadays, Large Language Models (LLMs) play a pivotal role in software engineering. Developers can use LLMs to address software development-related tasks such as documentation, code refactoring, debugging, and testing. ChatGPT, released by OpenAI, has ...

In recent years, Large Language Models (LLMs) have witnessed a remarkable ascent, with OpenAI's ChatGPT, introduced in 2022, garnering substantial attention. ChatGPT's rapid adoption in the software development community has opened up new avenues for ...

Large Language Models (LLMs), like ChatGPT, have gained widespread popularity and usage in various software engineering tasks, including refactoring, testing, code review, and program comprehension. Despite recent studies delving into refactoring ...

A platform-specific API is an API implemented for a particular platform (e.g., operating system), therefore, it may not work on other platforms than the target one. In this paper, we propose a first empirical study to assess the availability and usage of ...

Continuous Integration (CI) is a well-established practice in traditional software development, but its nuances in the domain of Machine Learning (ML) projects remain relatively unexplored. Given the distinctive nature of ML development, understanding ...

Dependency graphs support software maintenance and software ecosystem analysis. Several metrics can be used on top of these graph models but the set of such metrics is to evolve over time. Further, some metrics have a dynamic nature, requiring being able ...

Understanding and effectively managing Technical Debt (TD) remains a vital challenge in software engineering. While many studies on code-level TD have been published, few illustrate the business impact of low-quality source code. In this study, we ...

Mining software repositories is a useful technique for researchers and practitioners to see what software developers actually do when developing software. Tools like Boa provide users with the ability to easily mine these open-source software ...

Test smell refers to poor programming and design practices in testing and widely spreads throughout software projects. Considering test smells have negative impacts on the comprehension and maintenance of test code and even make code-under-test more ...

On open source software (OSS) platforms such as GitHub, forking and accepting pull-requests is an important approach for OSS projects to receive contributions, especially from external contributors who cannot directly commit into the source repositories. ...

Software testing is one of the most essential parts of the software lifecycle and requires a substantial amount of time and effort. During the software evolution, test cases should coevolve with the production code. However, the co-evolution of test ...

Third-party libraries (TPLs) have become an essential component of software, accelerating development and reducing maintenance costs. However, breaking changes often occur during the upgrades of TPLs and prevent client programs from moving forward. ...

Proper incentives are important for motivating developers in open-source communities, which is crucial for maintaining the development of open-source software healthy. To provide such incentives, an accurate and objective developer contribution ...
