KOWALSKI: Collecting API Clients in Easy Mode

Manuel Leuenberger, Haidar Osman, Mohammad Ghafari, and Oscar Nierstrasz. KOWALSKI: Collecting API Clients in Easy Mode. In Proceedings of the 33rd International Conference on Software Maintenance and Evolution, ICSME 2017, 2017. Details.


Understanding API usage is important for upstream and downstream developers. However, compiling a dataset of API clients is often a tedious task, especially since one needs many clients to draw a representative picture of the API usage. In this paper, we present KOWALSKI, a tool that takes the name of an API, then finds and downloads client binaries by exploiting the Maven dependency management system. As a case study, we collect clients of Apache Lucene, the de facto standard for full-text search, analyze the binaries, and create a typed call graph that allows developers to identify hotspots in the API. A video demonstrating how KOWALSKI is used for this experiment can be found at https://youtu.be/zdx28GnoSRQ.
