Move the Package Registry from EE to Core
<!-- The first four sections: "Problem to solve", "Intended users", "User experience goal", and "Proposal", are strongly recommended, while the rest of the sections can be filled out during the problem validation or breakdown phase. However, keep in mind that providing complete and relevant information early helps our product team validate the problem and start working on a solution. --> ### Problem to solve The goal of the GitLab Package Group is to have 90% of userbase rely on GitLab for all of their package management needs. In order to achieve this goal, we need to both [add support for a wide variety of package manager formats](https://gitlab.com/groups/gitlab-org/-/epics/1245) and build a robust set of features that will be sufficient for our customers to replace their existing package manager vendors. We would like to help drive the adoption of these features so that we can get more feedback on how to improve them and make them even more useful in your everyday workflows. And, as we've been working with the community on contributions for [Composer (PHP)](https://gitlab.com/gitlab-org/gitlab/issues/15886) and [Cargo (Rust)](https://gitlab.com/gitlab-org/gitlab/issues/33060), we've heard several requests move these features to core. ### Intended users * [Delaney (Development Team Lead)](https://about.gitlab.com/handbook/marketing/product-marketing/roles-personas/#delaney-development-team-lead) * [Sasha (Software Developer)](https://about.gitlab.com/handbook/marketing/product-marketing/roles-personas/#sasha-software-developer) * [Devon (DevOps Engineer)](https://about.gitlab.com/handbook/marketing/product-marketing/roles-personas/#devon-devops-engineer) * [Sidney (Systems Administrator)](https://about.gitlab.com/handbook/marketing/product-marketing/roles-personas/#sidney-systems-administrator) * [Simone (Software Engineer in Test)](https://about.gitlab.com/handbook/marketing/product-marketing/roles-personas/#simone-software-engineer-in-test) ### User experience goal <!-- What is the single user experience workflow this problem addresses? For example, "The user should be able to use the UI/API/.gitlab-ci.yml with GitLab to <perform a specific task>" https://about.gitlab.com/handbook/engineering/ux/ux-research-training/user-story-mapping/ --> ### Proposal As part of GitLab's [stewardship promises](https://about.gitlab.com/company/stewardship/#what-features-are-paid-only), we would like to move the basic functionality for each package manager format to the GitLab Core Edition. This means that for npm, Maven, NuGet, Conan and any future formats, you will be able to: * Establish GitLab as a private repository * Authenticate using your GitLab credentials, personal access or job token * Publish packages to GitLab * Pull packages from GitLab * Search for packages hosted on GitLab * Access an easy-to-use UI that displays package details and metadata and allows you to download any relevant files * Ensure that your contributions are available for ALL GitLab users ### Further details #### MR Breakdown 1. Move dependency files and code (fixtures, helper classes, etc) 1. Remove license checks in the backend 1. Move models 1. Move controlers/apis (with the dependencies moved and license removed, it should be able to be done with a simple move) 1. Remove checks in the UI and license <!-- Include use cases, benefits, goals, or any other details that will help us understand the problem better. --> ### Permissions and Security - There are no permissions changes required for this change <!-- 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)?--> ### 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/feature-change-workflow.html#documentation-requirements * 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 --> ### 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. --> ### 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/#four-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
