| Research Abstract |
We designed an XML representation for program execution traces and constucted a software environment for that. The environment includes trace generation tools and trace vizualization tools.
1.XML representation
Program traces reflect the nested nature of function calls of the program. XML offers tree structure suitable for program traces. However, for multi-threaded programs, the trace is overlapped each other and difficult to be represented in a single tree. We decided to use two XML representations : a tree structure suitable for single threaded programs which is easy to be processed by other tools, and a plain representaion suitable for multi-threaded programs.
2.Visualization tool
We implemented a trace visualization tool ETV. It is language independent, and offers random access within the traces. We evaluated this tool in a class of introductory programming in our university. We also extended this tool (1)to navigate a debugger using the trace, (2)embed the tool into the Eclipse IDE.
3.Other tools
We implemented several tools using the XML format traces, including a call graph generator and an execution-skelton generator (execution skelton is a subgraph of the static call graph whose edge is actually traced in the execution).
4.Software download
We made our software (the trace generator for Java programs and the ETV visualization tool) available in our web site.
