  Bug-fix benchmarks are fundamental in advancing various sub-fields of
software engineering such as automatic program repair (APR) and fault
localization (FL). A good benchmark must include recent examples that
accurately reflect technologies and development practices of today. To be
executable in the long term, a benchmark must feature test suites that do not
degrade overtime due to, for example, dependencies that are no longer
available. Existing benchmarks fail in meeting both criteria. For instance,
Defects4J, one of the foremost Java benchmarks, last received an update in
2020. Moreover, full-reproducibility has been neglected by the majority of
existing benchmarks. In this paper, we present GitBug-Actions: a novel tool for
building bug-fix benchmarks with modern and fully-reproducible bug-fixes.
GitBug-Actions relies on the most popular CI platform, GitHub Actions, to
detect bug-fixes and smartly locally execute the CI pipeline in a controlled
and reproducible environment. To the best of our knowledge, we are the first to
rely on GitHub Actions to collect bug-fixes. To demonstrate our toolchain, we
deploy GitBug-Actions to build a proof-of-concept Go bug-fix benchmark
containing executable, fully-reproducible bug-fixes from different
repositories. A video demonstrating GitBug-Actions is available at:
