In consecutive upgrades of a source code,some upgrade spots (code fragments) are overlapped: that is, ``chain of code changes.''Such chain would have a potential to make the development unstable. This paper investigates chain of code changes in an actual open source software.The empirical results show the followings:(1) chain's occarrence rate is about 10% in average; the rate becomeshigher within a few days after a upgrade or around 40 days after a upgrade. (2) ``code-addition''s would occur more change chains in their following versions. |
