Packages list page: display the most recent pipeline

🔥 Problem

In the page that lists the available packages, we show a pipeline if the package was built by one.

The problem is that, the package (name+version) can accept duplicates and so multiple pipelines could have built it. The index page is showing the oldest pipeline. That's a bit unexpected as the newest pipeline

Example: https://staging.gitlab.com/10io/pkgs_build_by_ci/-/packages

🚒 Solution

• Update the frontend GraphQL query so that pipelines(first: 1) is queried and not pipelines(last: 1).
• (Bonus) It seems that the field pipeline of the Rest API has the same behavior.
  • Updating it could be a breaking change, so I'll leave it as a Bonus point.

Implementation guide

• frontend Change last to first https://gitlab.com/gitlab-org/gitlab/-/blob/e66e89bf4932e6f666a73b5d3ef3c3ca73e3d83d/app/assets/javascripts/packages_and_registries/package_registry/graphql/fragments/package_data.fragment.graphql#L15
• rails
  • Change the method original_build_info to return the last build_info instead of the first https://gitlab.com/gitlab-org/gitlab/-/blob/master/app/models/packages/package.rb#L293
  • After the change above is done, the method needs to be renamed to something like last_build_info since it won't return original build info anymore.
