  Phabricator is a modern code collaboration tool used by popular projects like
FreeBSD and Mozilla. However, unlike the other well-known code review
environments, such as Gerrit or GitHub, there is no readily accessible public
code review dataset for Phabricator. This paper describes our experience mining
code reviews from five different projects that use Phabricator (Blender,
FreeBSD, KDE, LLVM, and Mozilla). We discuss the challenges associated with the
data retrieval process and our solutions, resulting in a dataset with details
regarding 317,476 Phabricator code reviews. Our dataset is available in both
JSON and MySQL database dump formats. The dataset enables analyses of the
history of code reviews at a more granular level than other platforms. In
addition, given that the projects we mined are publicly accessible via the
Conduit API, our dataset can be used as a foundation to fetch additional
details and insights.
