Statement coverage is commonly used as a measure of test suite quality. Coverage is often used as a part of a code review process: if a patch decreases overall coverage, or is itself not covered, then the patch is scrutinized more closely. Traditional studies of how coverage chan…
WebView is a widely used Android component that augments a native app with web browser capabilities. It eases the interactions between an app’s native code and web code. However, the interaction mechanism of WebView induces new types of bugs in Android apps. Understanding the cha…
Analyzing and understanding source code changes is important in a variety of software maintenance tasks. To this end, many code differencing and code change summarization methods have been proposed. For some tasks (e.g. code review and software merging), however, those differenci…
Developers can use different technologies for many software development tasks in their work. However, when faced with several technologies with comparable functionalities, it is not easy for developers to select the most appropriate one, as comparisons among technologies are time…
The control flows of Android apps are largely driven by the protocols that govern how callback APIs are invoked in response to various events. When these callback APIs evolve along with the Android framework, the changes in their invocation protocols can induce unexpected control…
Developers often need to search for appropriate APIs for their programming tasks. Although most libraries have API reference documentation, it is not easy to find appropriate APIs due to the lexical gap and knowledge gap between the natural language description of the programming…
As a developer, it is often complex to foresee the impact of changes in source code on usage, e.g., it is time-consuming to find out all components that will be impacted by a change or estimate the impact on the usability of a failing piece of code. It is therefore hard to decide…
Incremental build systems are essential for fast, reproducible software builds. Incremental build systems enable short feedback cycles when they capture dependencies precisely and selectively execute build tasks efficiently. A much overlooked feature of build systems is the expre…
Modern distributed version control systems, such as Git, offer support for branching — the possibility to develop parts of software outside the master trunk. Consideration of the repository structure in Mining Software Repository (MSR) studies requires a thorough approach to mini…
The behavior of complex software-intensive systems of systems often only fully emerges during operation, when all systems interact with each other and with their environment. Runtime monitoring approaches are thus used to detect deviations from the expected behavior, which is com…
In recent years, fuzz testing has proven itself to be one of the most effective techniques for finding correctness bugs and security vulnerabilities in practice. One particular fuzz testing tool, American Fuzzy Lop (AFL), has become popular thanks to its ease-of-use and bug-findi…
Dynamic slicing is a common way of identifying the root cause when a program fault is revealed. With the dynamic slicing technique, the programmers can follow data and control flow along the program execution trace to the root cause. However, the technique usually fails to work o…
Concurrency bugs of a multi-threaded program may only manifest with certain scheduling, i.e., they are heisenbugs which are observed only from time to time if we execute the same program with the same input multiple times. They are notoriously hard to fix. In this work, we propos…
It is time-consuming and labor-intensive to learn and locate the correct API for programming tasks. Thus, it is beneficial to perform API recommendation automatically. The graph-based statistical model has been shown to recommend top-10 API candidates effectively. It falls short,…
Binary code similarity detection (BCSD) has many applications, including patch analysis, plagiarism detection, malware detection, and vulnerability search etc. Existing solutions usually perform comparisons over specific syntactic features extracted from binary code, based on exp…
Smart contracts, as a promising and powerful application on the Ethereum blockchain, have been growing rapidly in the past few years. Since they are highly vulnerable to different forms of attacks, their security becomes a top priority. However, existing security auditing techniq…
The Android multitasking mechanism can be plagued with app switching attacks, in which a malicious app replaces the legitimate top activity of the focused app with one of its own, thus mounting, e.g., phishing and denial-of-service attacks. Existing market-level defenses are stil…
Commit messages can be regarded as the documentation of software changes. These messages describe the content and purposes of changes, hence are useful for program comprehension and software maintenance. However, due to the lack of time and direct motivation, commit messages some…
Software refactoring is widely employed to improve software quality. A key step in software refactoring is to identify which part of the software should be refactored. To facilitate the identification, a number of approaches have been proposed to identify certain structures in th…
Deep learning (DL) defines a new data-driven programming paradigm that constructs the internal system logic of a crafted neuron network through a set of training data. We have seen wide adoption of DL in many safety-critical scenarios. However, a plethora of studies have shown th…
