Processes for GitLab Shell

Releasing a new version

GitLab Shell is versioned by Git tags, and the version used by the Rails application is stored in GITLAB_SHELL_VERSION.

For each version, there is a raw version and a tag version:

  • The raw version is the version number. For instance, 15.2.8.
  • The tag version is the raw version prefixed with v. For instance, v15.2.8.

To release a new version of GitLab Shell and have that version available to the Rails application:

  1. Create a merge request to update the CHANGELOG with the tag version and the VERSION file with the raw version.

  2. Ask a maintainer to review and merge the merge request. If you're already a maintainer, second maintainer review is not required.

  3. Add a new Git tag with the tag version.

  4. Update GITLAB_SHELL_VERSION in the Rails application to the raw version.

    NOTE: This can be done as a separate merge request, or in a merge request that uses the latest GitLab Shell changes.

Security releases

GitLab Shell is included in the packages we create for GitLab. Each version of GitLab specifies the version of GitLab Shell it uses in the GITLAB_SHELL_VERSION file. Because of this specification, security fixes in GitLab Shell are tightly coupled to the GitLab patch release workflow.

For a security fix in GitLab Shell, two sets of merge requests are required:

  1. The fix itself, in the gitlab-org/security/gitlab-shell repository and its backports to the previous versions of GitLab Shell.
  2. Merge requests to change the versions of GitLab Shell included in the GitLab patch release, in the gitlab-org/security/gitlab repository.

The first step could be to create a merge request with a fix targeting main in gitlab-org/security/gitlab-shell. When the merge request is approved by maintainers, backports targeting previous 3 versions of GitLab Shell must be created. The stable branches for those versions may not exist, so feel free to ask a maintainer to create them. The stable branches must be created out of the GitLab Shell tags or versions used by the 3 previous GitLab releases.

To find out the GitLab Shell version used on a particular GitLab stable release, run this command, replacing 13-9-stable-ee with the version you're interested in. These commands show the version used by the 13.9 version of GitLab:

git fetch security 13-9-stable-ee
git show refs/remotes/security/13-9-stable-ee:GITLAB_SHELL_VERSION

Close to the GitLab patch release, a maintainer should merge the fix and backports, and cut all the necessary GitLab Shell versions. This allows bumping the GITLAB_SHELL_VERSION for gitlab-org/security/gitlab. The GitLab merge request is handled by the general GitLab patch release process.

After the patch release is done, a GitLab Shell maintainer is responsible for syncing tags and main to the gitlab-org/gitlab-shell repository.
