Defined in:

Overview

Analyze the sandbox to detect which Pods should be removed, and which ones should be reinstalled.

The logic is the following:

Added

  • If not present in the sandbox lockfile.
  • The directory of the Pod doesn't exits.

Changed

  • The version of the Pod changed.
  • The SHA of the specification file changed.
  • The specific installed (sub)specs of the same Pod changed.
  • The specification is from an external source and the installation process is in update mode.
  • The directory of the Pod is empty.
  • The Pod has been pre-downloaded.

Removed

  • If a specification is present in the lockfile but not in the resolved specs.

Unchanged

  • If none of the above conditions match.

end

#pod_added?(pod) ⇒ Boolean (private)

Note:

A Pod whose folder doesn't exists is considered added.

Returns whether the Pod with the given name should be installed.

Parameters:

  • pod (String)

    the name of the Pod.

Returns:

  • (Boolean)

    Whether the Pod is added.

  return true if !sandbox.local?(pod) && !folder_exist?(pod)
  false
end

#pod_changed?(pod) ⇒ Boolean (private)

Note:

In update mode, as there is no way to know if a remote source hash changed the Pods from external sources are always marked as changed.

Note:

A Pod whose folder is empty is considered changed.

Returns whether the Pod with the given name should be considered changed and thus should be reinstalled.

Parameters:

  • pod (String)

    the name of the Pod.

Returns:

  • (Boolean)

    Whether the Pod is changed.
