Programmers spend considerable time debugging code. Symbolic debuggers provide some help but the task remains complex and difficult. Other than breakpoints and tracing, these tools provide little high-level help. Programmers must perform many tasks manually that the tools could perform automatically, such as finding which statements in the program affect the value of an output variable for a gi...

The ability to debug programs composed using aspect-oriented programming (AOP) techniques is critical to the adoption of AOP. Nevertheless, many AOP systems lack adequate support for debugging, making it difficult to diagnose faults and understand the program‘s composition and control flow. We present an AOP debug model that characterizes AOP-specific program composition techniques and AOP-spec...

Program slicing is a general, widely-used, and accepted technique applicable to different software engineering tasks including debugging, whereas model-based diagnosis is an AI technique originally developed for finding faults in physical systems. During the last years it has been shown that model-based diagnosis can be used for software debugging. In this paper we discuss the relationship betw...

Debugging programs is a complicated and cumbersome task. It is an iterative process which includes hypothesizing the cause of a failure and validating the hypothesis. Since programs comprise of many components with complex interactions this chain often involves several trials. Fault localization (FL) is the task of identifying components that are likely to cause the failure. Automated fault loc...

Debugging and testing is a larger part of the effort spent in a software development cycle. Debugging a program is time consuming and is a continuous cycle of code modification and testing. The task of debugging depends on the environment, the language, the operating system: the problem: and more interestingly even the individual program. In this paper, we present a detailed implementation of s...

A program fails. Under which circumstances does this failure occur? One single algorithm, the delta debugging algorithm, suffices to determine these failure-inducing circumstances. Delta debugging tests a program systematically and automatically to isolate failureinducing circumstances such as the program input, changes to the program code, or executed statements.

Cyclic debugging is one of the most important and most commonly used activities in program development. During cyclic debugging, the program is repeatedly reexecuted to track down errors when a failure has been observed. This process necessitates reproducible program executions. Applying classical debugging techniques such using breakpoints or single stepping in real-time systems change the tem...

Debugging is an integral part of the software development cycle which can account for up to 50% of the development time of an application. This paper discusses some of the challenges speciic to real-time debugging. It explains how developing real-time applications can be supported by an environment which addresses the issues of time deadline monitoring and distortion due to the interference of ...

The task of debugging can be arduous. A bug can be evident with a single glance, or it can be hidden in the deepest lurking place of our program. Nevertheless, surprisingly, debugging is one of the software processes that has been mostly abandoned by the scientific community, and the same debugging techniques used twenty years ago are still being used today. The situation is not different regar...
