Abstract

Summary form only given. Developers have faced with tons of bugs. Fixing bugs is tedious and time-consuming. Typical bug resolution tasks include the identification of bug locations, the selection of bugs to fix, and the actual removal of them. This talk leads audiences to a journey of bug hunting by introducing three novel techniques, automatically locating, prioritizing, and fixing bugs. For bug localization, the two-phase localization model filters out deficient bug reports to avoid noisy input and enhance the accuracy of bug localization. The bug prioritization approach selects bugs to fix first, by using static information. The pattern-based program repair leverages human-written patches to automatically generate more acceptable bug patches.
