Isolating failure-inducing thread schedules

Abstract

Consider a multi-threaded application that occasionally fails due to non-determinism. Using the DEJAVU capture/replay tool, it is possible to record the thread schedule and replay the application in a deterministic way. By systematically narrowing down the difference between a thread schedule that makes the program pass and another schedule that makes the program fail, the Delta Debugging approach can pinpoint the error location automatically-namely, the location(s) where a thread switch causes the program to fail. In a case study, Delta Debugging isolated the failure-inducing schedule difference from 3.8 billion differences in only 50 tests.
