Leveraging Light-Weight Analyses to Aid Software Maintenance

We will evaluate our techniques and tools on large, real-world systems, comprising tens of millions of lines of code and thousands of defects. The proposed work will attempt to reduce the cost of three specific maintenance tasks: triaging automatically-generated defect reports, automatically synthesizing defect repairs, and automatically identifying out-of-date or incomplete system documentation. We hope to address bottlenecks in each of these three areas and show concrete time and effort savings for each process. The rest of this section describes each maintenance process and our proposed improvements in each case.
