Analysis of Software Evolution

We intend to assess the improvements of Gerrit. The central
concern is “Does Rietveld evolve into Gerrit as the developers intended?” To answer
this question, we first compare qualitative features of two code review tools. We
then conducted an interview with a developer of Gerrit and obtained the developer’s
original intention of improvements in Gerrit. By analyzing mined data from code
review logs, we try to explain the effects of improvements quantitatively. The result
of analysis showed us that the improvements of Gerrit that the developer is expected
are not observed explicitly.
