Class Method Details

.generate_version_locking_dependencies(lockfile, pods_to_update, pods_to_unlock = []) ⇒ Molinillo::DependencyGraph<Dependency>

Generates dependencies that require the specific version of the Pods that haven’t changed in the Lockfile.

These dependencies are passed to the Resolver, unless the installer is in update mode, to prevent it from upgrading the Pods that weren’t changed in the Podfile.

Parameters:

  • lockfile (Lockfile) —

    the lockfile containing dependency constraints

  • pods_to_update (Array<String>) —

    List of pod names which needs to be updated because installer is in update mode for these pods. Pods in this list and all their recursive dependencies will not be included in generated dependency graph

  • pods_to_unlock (Array<String>) (defaults to: []) —

    List of pod names whose version constraints will be removed from the generated dependency graph. Recursive dependencies of the pods won’t be affected. This is currently used to force local pods to be evaluated again whenever checksum of the specification of the local pods changes.

Returns:

  • (Molinillo::DependencyGraph<Dependency>) —

    the dependencies generated by the lockfile that prevent the resolver to update a Pod.

.unlocked_dependency_graph ⇒ Molinillo::DependencyGraph<Dependency>

Generates a completely ‘unlocked’ dependency graph.

Returns:

  • (Molinillo::DependencyGraph<Dependency>) —

    an empty dependency graph
