Abstract:
Previous work in software visualization has demonstrated the advantages of presenting programs in a graphical manner in both program understanding and debugging. Among the class of program visualization systems are those which operate non-intrusively on program sources. One of the major challenges faced by users of such systems is the problem of filtering the enormous amount of run-time information present during the execution of a large system. In this thesis, I describe an evolution of the Software Landscape. The Software Landscape is a tool for browsing a software system's static structure using boxes together with arrow and containment relations. My Run-Time Landscape includes run-time information, utilizes the Landscape paradigm for the elision of unwanted details, and provides a tightly integrated environment for viewing program artifacts from different perspectives. This prototype is useful in debugging, program understanding, and profiling. ii Acknowledgements I am grateful for the kind support of many people. First among those people, I wish to thank my supervisor Professor Richard C. Holt for his patience, guidance, and constructive criticism. I also thank Professor Dave B. Wortman, my second reader, for his helpful suggestions. The members of the Turing Group are appreciated for their support and involvement in my work. Many thanks to Spiros Mancoridis, Richard Holt, David Penny, Michael Godfrey, Brian Hall, and Gary Farmaner. Special thanks go to Ron Wessels for implementing the compiler-side of the prototype as I needed it. I would also like to thank Blaine Price, Professor Jim Cordy, and Wayne Hayes for their discussions and input on the Run-Time Landscape. To my friends in DCS, I thank you all for your friendship and support which made obtaining my M.Sc. a positive experience. My parents deserve special thanks for always standing behind me and raising me with a strong belief in higher education. Also, my brothers have been strong role models for me. Lastly, the generous financial support of the University of Toronto is gratefully awknowledged. iii To my parents
