A dataset of GitHub Actions workflow histories

This replication package accompagnies the dataset and exploratory empirical analysis reported in the paper "A dataset of GitHub Actions workflow histories" published in the IEEE MSR 2024 conference. The Jupyter notebook Exploratory_Analysis.ipynb requires Python 3.11.6 and some dependencies that are listed in the notebook and in the file "requirements_notebook.txt". "workflows.tar.gz" contains the dataset of GitHub Actions workflow file histories. "repositories.csv.gz" contains metadata about the GitHub repositories containing the workflow files. This metadata was extracted using the SEART GitHub Search tool. "workflows.csv.gz" contains the metadata for the extracted workflow files. The metadata is separated in different columns: `repository`: The repository (author and repository name) from which the workflow was extracted. The separator "---" allows to distinguish between the author and the repository name. `commit_hash`: The commit hash returned by git `author_name`: The name of the author that changed this file `author_email`: The email of the author that changed this file `committer_name`: The name of the committer `committer_email`: The email of the committer `committed_date`: The committed date of the commit `authored_date`: The authored date of the commit `file_path`: The path to this file in the repository `previous_file_path`: The path to this file before it has been touched `file_hash`: The name of the related workflow file in the dataset `previous_file_hash: The name of the related workflow file in the dataset, before it has been touched `change_type`: A single letter (A,D or M) representing the type of change made to the workflow (Added, Deleted or Modified) "auxiliaries.csv.gz" is a similar file for auxiliary files.
