Generally, software evolutions including quality improvements and feature developments
are undergone through the source code changes.
Code changes are categorized into two types, primary changes and secondary changes:
a primary change is a code change directly caused by bug fix and/or feature change;
a secondary change is a code change caused by other changes including a primary change or
another secondary change.
Controlling secondary changes can be effective in order to control amount of code changes, i.e. patch sizes.
This paper investigates the incidence rate and the change behaviour during upgrades in actual open source software.
Moreover, this paper focuses on code relationships based on dependencies or code clones
as the major factors of secondary changes. For each factor, the incidence trends are analyzed using the survival analysis.
The empirical results show the followings: (1) the incidence rate of secondary change is about $38\%$ in all changes; (2) the incidence rate of secondary change caused by dependency relation is about $17.3\%$, and the rate by code clone relation is about $25.6\%$;
(3) some of the secondary changes caused by dependency relation
would occur later (within $150$ days; $5.1\%$).
On the other hands, most of the secondary changes by code clone relation occur simultaneously. |
