| Abstract(in English) | A code clone that is duplicated code section in source files makes software maintenance more difficult. However, to our knowledge, no study has analyzed how the code clone influences software reliability. In this paper, we focused on the length of the code clone in order to analyze the relation between software reliability and code clone. We analyzed a repository of a project, classified source code files according to the length of the code clone included in the files, and measured the bug density of each classified file group. As a result, it was clarified that (1) the bug density of the file group that contained a short code clone was high, and (2) the bug density of the file group that contained a long code clone was low. In addition, because we had thought the bug density was influenced from the length of each source code file, we classified the files by measuring lines of source code and examined how much the bug density of each file group changed. We observed that the result (1), (2) became more pronounced when lines of source code was comparatively large. |
