![](artwork/logo.png) # Contribution Complexity ## What is this? This tool computes the complexity of a specified contribution to a git repository. A contribution is one or more commits specified by their commit hashes. Alternatively, if commit messages contain references to issue numbers, a contribution can be specified by a regular expression matching a certain set of commits. The tool reports a contribution complexity on the scale `low`, `moderate`, `medium`, `elevated`, `high`. That value identifies weather a contribution was simple to make (value `low`) or if it consists of multiple intricate changes (value `high`) that were difficult to integrate into the system. For example, the storage engine of [Apache Cassandra](https://cassandra.apache.org/) (DBMS) was refactored for version 3 to better support certain concepts of the query language and to allow for future performance optimizations, see [ticket `CASSANDRA-8099`](https://issues.apache.org/jira/browse/CASSANDRA-8099) The [corresponding commit](https://github.com/apache/cassandra/commit/a991b64811f4d6adb6c7b31c0df52288eb06cf19) modifies almost 50k lines in 645 files and contains many non-trivial changes. On the other hand a [bug](https://issues.apache.org/jira/browse/CASSANDRA-12886) that prevented under certain circumstances streaming between cluster nodes was fixed with a [quite tiny patch](https://github.com/apache/cassandra/commit/06feaefba50301734c490521d720c8a482f638e4) modifying 15 lines in two files. For humans inspecting the two contributions it is quickly clear that the former contribution is way more complex to implement than the latter. This tool is meant to automate the process of identification of contributions of various complexities either for inclusion in a CI setup or for research.   ## Installation ```bash $ pip install contribution-complexity ``` ## Running You can run the tool either by specifying a list of commits or by providing a regular expression that matches commit messages containing ```bash $ contribcompl commits <path_to_repo> <commit_shas>... $ contribcompl issue <path_to_repo> <issue_regex>... ``` For example, ```bash $ git clone git@github.com:apache/Cassandra.git /tmp/cassandra $ contribcompl commits /tmp/cassandra 021df085074b761f2b3539355ecfc4c237a54a76 2f1d6c7254342af98c2919bd74d37b9944c41a6b ContributionComplexity.LOW $ contribcompl issue /tmp/cassandra 'CASSANDRA-8099( |$)' ContributionComplexity.HIGH ``` ## Calling from Code ```python from contribution_complexity.compute import find_commits_for_issue from contribution_complexity.metrics import compute_contrib_compl issue_re = "CASSANDRA-8099( |$)" path_to_repo = "/tmp/cassandra" commit_shas = find_commits_for_issue(path_to_repo, issue_re) contribcompl = compute_contrib_compl(path_to_repo, commit_shas) print(contribcompl) ``` ---------------- # Recreating the Experiment ## Requirements * [Vagrant](https://www.vagrantup.com) with [DigitalOcean plugin](https://github.com/devopsgroup-io/vagrant-digitalocean) * A [DigitalOcean account](https://www.digitalocean.com/) * [SSH keys registered with DigitalOcean](https://www.digitalocean.com/community/tutorials/how-to-set-up-ssh-keys-on-ubuntu-1804) * The SSH key name on an environment variable `SSH_KEY_NAME` * A [DigitalOcean API token](https://docs.digitalocean.com/reference/api/create-personal-access-token/) on an environment variable `DIGITAL_OCEAN_TOKEN` ## Run! * Set your Github API key in the `Vagrantfile`, i.e., replace `<PUT_YOUR_KEY_HERE>` on line 33 with your key. * Run `vagrant up` in this directory, which will bring up and configure a VM accordingly. It will automatically start the experiment recreation, which will take some hours to run. * Once done you have all results on the VM (log onto the machine with `vagrant ssh`) in the directory `/vagrant/data/` The experiment is described in `experiment/run_experiment.sh`. ### Attribution The logo is adapted from a [flaticon icon](on https://www.flaticon.com/free-icon/puzzle_808497?term=contribution&page=1&position=16&page=1&position=16&related_id=808497&origin=search).
