Dataset

The dataset contains the results and metrics computed by the approach for analysis and propagation of feature revisions presented in the paper: Analysis and Propagation of Feature Revisions in Preprocessor-based Software Product Lines. The dataset contains information on the target releases of four real-world preprocessor-based systems (LibSSH, SQLite, Irssi, and Bison) used for evaluating our approach. Such information is the number of commits in between a pair of origin and destination releases, features of each release, number of patches, files and lines of code differing between a origin and destination release, number of features revised, introduced and deleted in relation to origin and destination target release. Further, it is available the runtime performance (ms) for each pair of release used as target to propagate features in space and time. For each feature propagated, it is available the number of lines of code added, removed, number of conditional blocks, files and feature interactions affected by the patches of code propagated.
