Many researchers have studied the behaviour of successful developers while debugging desktop software. In this paper, we investigate the embedded-software debugging by intermediate programmers through an exploratory study. The bugs are semantic low-level errors, and the participants are students who completed a real-time operating systems course in addition to five other programming courses. We compare...
Software systems with quality of service (QoS), such as database management systems and web servers, are ubiquitous. Such systems must meet strict performance requirements. Instrumentation is a useful technique for the analysis and debugging of QoS systems. Dynamic binary instrumentation (DBI) extracts runtime information to comprehend system's behavior and detect performance bottlenecks. However,...
Program analysis tools are essential for understanding programs, analyzing performance, and optimizing code. Some of these tools use code instrumentation to extract information at runtime. The instrumentation process can alter program behavior such as timing behavior and memory consumption. Time-sensitive programs, however, must meet specific timing constraints and thus require that the instrumentation...
Tracing is a well-established method for debugging programs. Current approaches aim only at preserving functional correctness during the instrumentation. Preservation of functional correctness is a necessary feature of all instrumentation tools. However, few existing instrumentation tools preserve extra-functional properties of a program. Specific classes of software are unable to leverage software...
