### Release notes None <!-- What is the problem and solution you're proposing? This content sets the overall vision for the feature and serves as the release notes that will populate in various places, including the [release post blog](https://about.gitlab.com/releases/categories/releases/) and [Gitlab project releases](https://gitlab.com/gitlab-org/gitlab/-/releases). " --> ### Problem to solve Currently the default message from GitLab on Merges is the same default as the `git merge` command. The problem is that for some script and Jira automation we are unable on merges to interrogate the commits messages of the branch in order to capture all the Jira issues that need to be updated automatically. Git provides on `git merge` the `--log` option that captures all the relevant commit messages being merged in. As a Merge Request resolver, I want to be able to merge through GitLab and have the message on my merge commit contain the relevant commit messages from what is being merged in instead of just a plain default, so that I can use that information for other processes that update relevant tracking systems accordingly. ### Intended users Developers, Maintainers and Owners of Repositories/Groups ### User experience goal The user should be able to toggle a setting on for Repository or Group and see that merge requests on merge have more than the default merge commit message and includes those that come with the `git merge --log` command ### Proposal I propose that GitLab offer a new setting at the Group and Repository levels where the parent setting overrides the Child. The setting would be added to General-> Merge Requests -> Merge Options section. The option would say "Should include relevant commits to merge in merge commit message" If selected the option would add to the `git merge` command the option `--log`. If not selected then it would remain as is. ### Further details <!-- Include use cases, benefits, goals, or any other details that will help us understand the problem better. --> ### Permissions and Security <!-- What permissions are required to perform the described actions? Are they consistent with the existing permissions as documented for users, groups, and projects as appropriate? Is the proposed behavior consistent between the UI, API, and other access methods (e.g. email replies)? Consider adding checkboxes and expectations of users with certain levels of membership https://docs.gitlab.com/ee/user/permissions.html * [ ] Add expected impact to members with no access (0) * [ ] Add expected impact to Guest (10) members * [ ] Add expected impact to Reporter (20) members * [ ] Add expected impact to Developer (30) members * [ ] Add expected impact to Maintainer (40) members * [ ] Add expected impact to Owner (50) members --> ### Documentation <!-- See the Feature Change Documentation Workflow https://docs.gitlab.com/ee/development/documentation/workflow.html#for-a-product-change * Add all known Documentation Requirements in this section. See https://docs.gitlab.com/ee/development/documentation/workflow.html * If this feature requires changing permissions, update the permissions document. See https://docs.gitlab.com/ee/user/permissions.html --> ### Availability & Testing <!-- This section needs to be retained and filled in during the workflow planning breakdown phase of this feature proposal, if not earlier. What risks does this change pose to our availability? How might it affect the quality of the product? What additional test coverage or changes to tests will be needed? Will it require cross-browser testing? Please list the test areas (unit, integration and end-to-end) that needs to be added or updated to ensure that this feature will work as intended. Please use the list below as guidance. * Unit test changes * Integration test changes * End-to-end test change See the test engineering planning process and reach out to your counterpart Software Engineer in Test for assistance: https://about.gitlab.com/handbook/engineering/quality/test-engineering/#test-planning --> ### Available Tier <!-- This section should be used for setting the appropriate tier that this feature will belong to. Pricing can be found here: https://about.gitlab.com/pricing/ * Free * Premium/Silver * Ultimate/Gold --> ### What does success look like, and how can we measure that? <!-- Define both the success metrics and acceptance criteria. Note that success metrics indicate the desired business outcomes, while acceptance criteria indicate when the solution is working correctly. If there is no way to measure success, link to an issue that will implement a way to measure this. Create tracking issue using the the Snowplow event tracking template. See https://gitlab.com/gitlab-org/gitlab/-/blob/master/.gitlab/issue_templates/Snowplow%20event%20tracking.md --> ### What is the type of buyer? <!-- What is the buyer persona for this feature? See https://about.gitlab.com/handbook/marketing/product-marketing/roles-personas/buyer-persona/ In which enterprise tier should this feature go? See https://about.gitlab.com/handbook/product/pricing/#three-tiers --> ### Is this a cross-stage feature? <!-- Communicate if this change will affect multiple Stage Groups or product areas. We recommend always start with the assumption that a feature request will have an impact into another Group. Loop in the most relevant PM and Product Designer from that Group to provide strategic support to help align the Group's broader plan and vision, as well as to avoid UX and technical debt. https://about.gitlab.com/handbook/product/#cross-stage-features --> ### Links / references <!-- Label reminders - you should have one of each of the following labels.
