repository-catalog Specification

Purpose

Define shared organization, repository identity, naming, and named access configuration for the GitHub, GitLab, and Forgejo infrastructure consumers.

Requirements

Requirement: Authoritative organization and repository inventory

The repository catalog SHALL store shared defaults and schema version at its root, one configuration file per organization, and one configuration file per repository beneath its organization. Those records SHALL own the configured organizations, repositories, named administrators, and named developers. Each forge consumer SHALL use that catalog for its selected repositories and named roles, preserving forge-specific settings without maintaining another copy of the inventory. Authentication and service-specific grants SHALL remain with their existing owners.

Scenario: Consume one organization definition

  • WHEN an organization assigns named administrators and developers and selects repositories for multiple forges
  • THEN each selected consumer uses the same catalog assignments and repository identities
  • AND forge-specific settings and service identities remain with their declared owners

Requirement: Stable names follow ownership and original upstream

First-party repository names SHALL remain the same across forges, including when copied or synchronized. External forks and mirrors SHALL belong to a catalog organization and use a name derived from the original upstream’s reversed hostname followed by its full owner and repository path, in lowercase with punctuation replaced by underscores. Cross-forge copies of external repositories SHALL retain that name rather than naming the intermediate copy as their upstream.

Scenario: Copy an organization-owned repository

  • WHEN the first-party alwaldend/src repository is copied from GitHub to GitLab or Forgejo
  • THEN its destination remains alwaldend/src

Scenario: Fork an external repository

  • WHEN https://gitlab.com/fdroid/fdroiddata is forked into alwaldend
  • THEN its organization-owned name is alwaldend/com_gitlab_fdroid_fdroiddata
  • AND subsequent copies on another forge retain that name

Requirement: Named developer access excludes protected default writes

Consumers SHALL grant catalog administrators administrative access and catalog developers repository reads, feature-branch writes, and pull or merge request creation. Catalog developers SHALL NOT receive direct push or merge access to protected default branches through their named roles or overlapping retained grants. Existing service-specific permissions SHALL be preserved and distinguished from named developer assignments.

Scenario: Develop on a feature branch

  • WHEN a catalog developer accesses a selected repository
  • THEN the developer can read its contents, create a feature branch, and open a pull or merge request
  • AND the developer cannot push or merge to its protected default branch

Requirement: Adopt existing resources without recreation

Consumers SHALL adopt existing remote resources through imports and preserve their remote identities. Existing managed resource addresses SHALL remain stable or use explicit state-preserving moves. Existing GitHub repository settings and Pages configuration SHALL remain intact, and default branches SHALL remain unchanged. No deletion or replacement SHALL execute without separate user approval for its concrete scope.

Scenario: Adopt an existing repository

  • WHEN a catalog repository already exists remotely or in Terraform state
  • THEN its import or state move preserves the existing remote repository ID and contents
  • AND the reviewed plan does not recreate it to resolve a name collision

Scenario: Encounter a destructive plan

  • WHEN any reviewed plan proposes a deletion or replacement
  • THEN execution of that operation stops pending the user’s explicit approval for the identified operation and scope

Requirement: GitLab copies and fork preserve their source identity

GitLab SHALL receive a one-time Git import of every catalog-selected GitHub repository and an organization-owned fork of the selected F-Droid metadata upstream. Imports SHALL preserve the source default branch, and the fork SHALL retain its upstream fork relationship. This change SHALL configure no ongoing synchronization.

Scenario: Complete the initial GitLab population

  • WHEN the GitHub default-branch migration completes and the initial GitLab imports and fork finish
  • THEN every selected GitHub repository has its intended GitLab copy and source default branch
  • AND the metadata repository retains its F-Droid upstream fork identity
  • AND later upstream changes are not promised to synchronize

Requirement: Adopt GitLab default-branch protections without removal

GitLab default-branch access SHALL be established through group defaults before new repositories are populated. Existing automatically created protections SHALL be verified and imported before standalone protection management is applied. Adoption SHALL preserve the existing protections; provider limitations SHALL be reported rather than bypassed by unprotecting or recreating them.

Scenario: Adopt an automatically protected default branch

  • WHEN an imported GitLab repository has an existing default-branch rule
  • THEN Terraform adopts that rule by import before applying permitted in-place access changes
  • AND adoption does not invoke unprotect-and-recreate behavior
