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...
In this paper, we propose an automated technique for optimal instrumentation of multi-threaded programs for debugging and testing of concurrent data structures. We define a notion of observability that enables debuggers to trace back and locate errors through data-flow instrumentation. Observability in a concurrent program enables a debugger to extract the value of a set of desired variables through...
The literature of runtime verification mostly focuses on event-triggered solutions, where a monitor is invoked by every change in the state of the system and evaluates properties of the system. This constant invocation introduces two major drawbacks to the system under scrutiny at run time: (1) significant overhead and (2) unpredictability. To circumvent the latter drawback, in this paper, we introduce...
The goal of runtime verification is to monitor the behavior of a system to check its conformance to a set of desirable logical properties. The literature of runtime verification mostly focuses on event-triggered solutions, where a monitor is invoked when an event of interest occurs (e.g., change in the value of some variable). At invocation, the monitor evaluates the set of properties of the system...
