Generating Fixes from Object Behavior Anomalies

Download www.st.cs.uni-saarland.de

Advances in recent years have made it possible in some cases to locate a bug (the source of a failure) automatically. But debugging is also about correcting bugs. Can tools do this automatically? The results reported in this paper, from the new PACHIKA tool, suggest that such a goal may be reachable. PACHIKA leverages diﬀerences in program behavior to generate program ﬁxes directly. It automatically infers object behavior models from executions, determines diﬀerences between passing and failing runs, generates possible ﬁxes, and assesses them via the regression test suite. Evaluated on the ASPECTJ bug history, PACHIKA generates a valid ﬁx for 3 out of 18 crashing bugs; every ﬁx pinpoints the bug location and passes the ASPECTJ test suite.
