Proposal

Switchboard has some validations for GitLab packages:

TAGGED_RELEASE_REGEX = /\A[0-9]{1,2}\.[0-9]{1,2}\.[0-9]{12}-[0-9a-f]{11}\.[0-9a-f]{11}\z/ # i.e 15.7.202211240820-5f3539354de.75a10ecec64
SIMPLE_RELEASE_REGEX = /\A[0-9]{1,2}\.[0-9]{1,2}\.[0-9]{1,2}\z/ # i.e 15.6.4
PRE_RELEASE_REGEX = Regexp.union([TAGGED_RELEASE_REGEX, SIMPLE_RELEASE_REGEX])

We need to adapt these to accept the new internal release notation, while maintaining backward compatibility.

---

Make sure models/serializers/UI are all aligned to account for the schema change.

Important points to consider

• The omnibus package and the CNG package should be the same. For example, the sandbox got tested with different package name than the CNG one, hence changes in multiple places in Instrumentor
  • https://gitlab.com/gitlab-com/gl-infra/gitlab-dedicated/instrumentor/-/merge_requests/4181/diffs#da1e8b4b54dd1372e9e864b8aab1f43164e11bad
• We need to guarantee compatibility with regular packages (from patches) and internal packages (from internal releases)

Exit Criteria

• Switchboard can accept the new notation without raising issues.
• Dedicated team reviews this change.
