An empirical study on bug propagation through code cloning.
Journal of Systems and Software(2019)
摘要
•Around 18.42% of the buggy code clones are involved with bug propagation.•Near-miss clones have a higher tendency of bug-propagation than identical clones.•Method clones are mostly involved with bug-propagation.•Severe bugs can sometimes get propagated through code cloning.•Copying a previously committed code fragment is safer than copying an uncommitted fragment.
