How can my code tell if it's inside the packaging org?

Question

I can think of at least three different 'environments' for my code:

1. installed, in a customer org,

2. unmanaged, in a cloned dev org,

3. managed, in the packaging org,

The first case can be covered by UserInfo.isCurrentUserLicensed('ns')

The second case can be covered by SObjectType.KnownObject__c.Name.startsWith('ns__')

But I'm actually struggling to differentiate the second and third case! Any ideas?

Answer 1

Once you have a managed package you will know the Org id of your packaging org (and that's never going to change). In your code you could check the Org Id using UserInfo.getOrganizationId() against the packaging org id (hard-coded)

(1) the namespace will be present, but the org id will not be the same as the packaging org id
(2) the namespace will be absent
(3) the namespace will be present, and the org id will be the same as the packaging org id
