We present PeASS (Performance Analysis of Software System versions), a tool for detecting performance changes at source code level that occur between different code versions. By using PeASS, it is possible to identify performance regressions that happened in the past to fix them.…
Localization of the root causes for unreproducible builds during software maintenance is an important yet challenging task, primarily due to limited runtime traces from build processes and high diversity of build environments. To address these challenges, in this paper, we propos…
Developers often look for solutions to programming problems in community Q&A sites like Stack Overflow. Due to the crowdsourcing nature of these Q&A sites, many user-provided answers are wrong, less optimal or out-of-date. Relying on community-curated quality indicators (e.g., ac…
Modern software often exists in many different, yet similar versions and/or variants, usually derived from a common code base (e.g., via clone-and-own). In the context of product-line engineering, family-based analysis has shown very promising potential for improving efficiency i…
This paper presents Sip4J, a fully automated, scalable and effective tool to automatically generate access permission contracts for a sequential Java program. The access permission contracts, which represent the dependency of code blocks, have been frequently used to enable concu…
The ability to repeat the execution of a program is a fundamental requirement in many areas of computing from computer system evaluation to software engineering. Reproducing executions of mobile apps, in particular, has proven difficult under real-life scenarios due to multiple s…
Developers often reuse code snippets from online forums, such as Stack Overflow, to learn API usages of software frameworks or libraries. These code snippets often contain ambiguous undeclared external references. Such external references make it difficult to learn and use those …
Bugs in commercial software and third-party components are an undesirable and expensive phenomenon. Such software is usually released to users only in binary form. The lack of source code renders users of such software dependent on their software vendors for repairs of bugs. Such…
For delivering high-quality artifacts within the budget and on schedule, software delivery teams ideally should have a holistic and in-process view of the current health and future trajectory of the project. However, such insights need to be at the right level of granularity and …
As an important extension of symbolic execution (SE), probabilistic symbolic execution (PSE) computes execution probabilities of program paths. Using this information, PSE can prioritize path exploration strategies. To calculate the probability of a path PSE relies on solution co…
Modern software delivery happens in a geographically distributed environment and resembles like a supply chain - consists of various participants, involves various phases, needs adherence to multiple regulations and needs to maintain artifacts' integrity throughout the delivery p…
Automated testing techniques are often assessed on coverage based metrics. However, despite giving good coverage, the test cases may miss the gap between functional specification and the code implementation. This gap may be subtle in nature, arising due to the absence of logical …
The error repair process in software systems is, historically, a resource-consuming task that relies heavily in developer manual effort. Automatic program repair approaches enable the repair of software with minimum human interaction, therefore, mitigating the burden from develop…
Bug localization is well-known to be a difficult problem in software engineering, and specifically in compiler development, where it is beneficial to reduce the input program to a minimal reproducing example; this technique is more commonly known as delta debugging. What addition…
Modern embedded systems are increasingly complex and contain multiple software layers from BSP (Board Support Packages) to OS to middleware to AI (Artificial Intelligence) algorithms like perception and voice recognition. Integrations of inter-layer and intra-layer in embedded sy…
Since the performance issues of apps can influence users' experience, developers leverage application performance management (APM) tools to locate the potential performance bottleneck of their apps. Unfortunately, most developers do not understand how APMs monitor their apps duri…
Recent trends in Web development demonstrate an increased interest in serverless applications, i.e. applications that utilize computational resources provided by cloud services on demand instead of requiring traditional server management. This approach enables better resource man…
As data volume and complexity grow at an unprecedented rate, the performance of data analytics programs is becoming a major concern for developers. We observed that developers sometimes use alternative data analytics APIs to improve program runtime performance while preserving fu…
Industry widely uses unstructured merge tools that rely on textual analysis to detect and resolve conflicts between code contributions. Semistructured merge tools go further by partially exploring the syntactic structure of code artifacts, and, as a consequence, obtaining signifi…
Test code is becoming more essential to the modern software development process. However, practitioners often pay inadequate attention to key aspects of test code quality, such as bug detectability, maintainability and speed. Existing tools also typically report a single test cod…
