Abstract

Debugging is a tedious and costly process that demands a profound understanding of the dynamic behavior of programs. An omniscient debugger makes the task of tracking down the root cause of bugs straightforward by enabling programmers to seamlessly navigate a buggy program's execution history. So why don't we all have an omniscient debugger in our favorite development environment? Are the challenges of making omniscient debugging practical a definitive barrier to its adoption? This article describes TOD, a scalable omniscient debugger for Java. TOD is integrated into the Eclipse IDE and paves the way for practical omniscient debugging. © 2009 IEEE.
