Content

It contains the bug fix commit dataset of An Empirical Study on Real Bug Fixes (ICSE 2015).

• The 5 *orig.txt contain the SVN commit identifiers. The files were given by Hao Zhong in a private communication, expect for Cassandra, whose commit list has been reconstructed. The format of the fourth column is {commit id}_{issue id}. If the issue id is “internal”, it means that the commit has been included because the commit message uses "bug" or "fix".
• The 14914 log.d/* files contains the commit metadata (message, author, date)
• The 14914 svn.d/* files contains the files touched by the commits (the file name contains the commit identifier)
• The 5956 jira.d/* files contains the JSON data of the JIRA bug reports mentioned in the commit messages

The two python files create a bug JSON file called bug-fix-commit-dataset.json with all information merged.
