There is a need for a subtree split of Drupal core to exist on Drupal.org. This will allow site administrators to install Drupal core via git, a git submodule, or via Composer.</p> <p>This issue is currently blocking <span class="drupalorg-gitlab-issue-link project-issue-status-info project-issue-status-3"><a href="https://www.drupal.org/project/drupal/issues/2372815" title="Status: Closed (duplicate)">#2372815: [meta] Make the &lt;root&gt;/composer.json file a working example</a></span>.</p> <h3 id="summary-proposed-resolution">Proposed resolution</h3> <p>Create and maintain subtree split of Drupal core.</p> <p>This should be a "Read-only" repository and will live at:<br> <del><a href="http://drupal.org/project/core">http://drupal.org/project/core</a></del><a href="http://github.com/drupal/core">http://github.com/drupal/core</a></p> <p>This is similar to Symfony's subtree split of Symfony's components:<br> <a href="https://github.com/symfony">https://github.com/symfony</a></p> <p>Some work has already been done to create a subtree split of Drupal core (via a script) here:<br> <a href="https://github.com/drupal-composer/drupal-core">https://github.com/drupal-composer/drupal-core</a></p> <p>Ideally, the split should happen every time a commit is pushed to the primary drupal repository via a <a href="http://git-scm.com/book/en/Customizing-Git-Git-Hooks">git hook</a>. However if that is not possible, it should at least occur every release (i.e. beta1, beta2, etc.). I believe Symony does it nightly, the more often, the better.</p> <h3 id="summary-remaining-tasks">Remaining tasks</h3> <ol> <li>create the drupal/core repo on github</li> <li>Move existing subtree commits from drupal-composer/drupal-core to drupal/core repo</li> <li>Add code to drupalorg to create subtree splits utilizing splitsh, and push those changes to github, and have it push 8.2.x-dev branch as a whole new branch to github.drupal.org</li> <li>Configure the git hooks on github</li> <li>Repoint (or recreate) <a href="https://packagist.org/packages/drupal/core">drupal/core</a> on Packagist to the official subtree split</li> </ol> > Related issue: [Issue #1975220](https://www.drupal.org/node/1975220) > Related issue: [Issue #2002304](https://www.drupal.org/node/2002304) > Related issue: [Issue #2372815](https://www.drupal.org/node/2372815)
