A visual prototype of Drupal.org's GitLab integration

What this post added

This post details the technical collaboration between Drupal.org and GitLab to integrate Drupal.org's version control system with GitLab. Key contributions include: - Drupal.org developing a `versioncontrol_gitlab` module that extends the `versioncontrol_git` module. - Collaboration with the GitLab engineering team to address specific issues, including: - `git merge-base web API` - API for confirming user email addresses - Configuration of display URL for clone instructions - Ability to hide user email addresses from GitLab UI - Allowing developer role to delete tags - Setting `GL_REPOSITORY` in update hooks for API-initiated requests - Deduplication of Git objects to reduce disk space of repository forks.
