Seminář: Mining software repositories with modified compiler

Alive software projects require continuous improvements. It is necessary to fix bugs, introduce new features in nearly every new release. However it is much more rare to remove already included features. As a result the code base size grows and the bug count increases. Yet, the number of people working on the project is often the same, which means that the same number of developers has to maintain more and more. The presentation consists of approach for mining history of software repository by using patched compiler. The mining history process with patched compiler was integrated with continuous building system (Hudson[1]). It is demonstrated on NetBeans[2] project together with mining data from bug database and creating connection between bug database and software revision repository.
