Optimal Tracing and Incremental Reexecution for Debugging Long-Running Programs

  title={Optimal Tracing and Incremental Reexecution for Debugging Long-Running Programs},
  author={Robert H. B. Netzer and Mark H. Weaver},
Debugging requires execution replay. Locations of bugs are rarely known in advance, so an execution must be repeated over and over to track down bugs. A problem arises with repeated reexecution for long-running programs and programs that have complex interactions with their environment. Replaying long-running programs from the start incurs too much delay. Replaying programs that interact with their environment requires the difticult (and sometimes impossible) task of exactly reproducing this… CONTINUE READING
