In the course of a framework's evolution, changes ranging from a simple refactoring to a complete rearchitecture can break client programs. Finding suitable replacements for framework elements that were accessed by a client program and deleted as part of the framework's evolution can be a challenging task. We present a recommendation system, SemDiff, that(More)
When developers join a software development project, they find themselves in a <i>project landscape</i>, and they must become familiar with the various landscape features. To better understand the nature of project landscapes and the integration process, with a view to improving the experience of both newcomers and the people responsible for orienting them,(More)
Large frameworks and libraries require extensive developer learning resources, such as documentation and mailing lists, to be useful. Maintaining these learning resources is challenging partly because they are not explicitly linked to the frameworks' API, and changes in the API are not reflected in the learning resources. Automatically recovering(More)
As a framework evolves, changes in its Application Programming Interface (API) can break client programs that extend the framework. Repairing a client program can be a challenging task because developers need to understand the context surrounding the API change. This paper describes SemDiff, a tool that recommends replacements for framework methods that(More)
Developer documentation helps developers learn frameworks and libraries. To better understand how documentation in open source projects is created and maintained, we performed a qualitative study in which we interviewed core contributors who wrote developer documentation and developers who read documentation. In addition, we studied the evolution of 19(More)
As part of the evolution of software systems, effort is often invested to discover in what parts of the source code a feature (or other concern) is implemented. Unfortunately, knowledge about a concern's implementation can become invalid as the system evolves. We propose to mitigate this problem by automatically inferring structural patterns among the(More)
Software reuse through Application Programming Interfaces (APIs) is an integral part of software development. The functionality offered by an API is not always accessed uniformly throughout the lifetime of a client program. We propose Temporal API Usage Pattern Mining to detect API usage patterns in terms of their time of introduction into client programs.(More)
Using and extending a framework is a challenging task whose difficulty is exacerbated by the poor documentation that generally comes with the framework. Even in the presence of documentation, developers often desire implementation examples for concrete guidance. We propose an approach that automatically locates implementation examples from a code base given(More)
SUMMARY During software maintenance tasks, developers often spend a valuable amount of effort investigating source code. This effort can be reduced if tools are available to help developers navigate the source code effectively. We studied to what extent developers can benefit from information contained in clusters of change sets to guide their investigation(More)
