Until now I've managed to avoid having to implement this piece quite
easily. The only temptation to implement it has been pseudo-client
features, which are basically just a workaround until Vervis gets a
separate client app.
But now, Person actors need to be able to automatically send
delegator-Grants when they receive a direct-Grant from a resource they
either asked to Join or got an Invite to. So, this creates a need to
track these joins and invites on the server side.
I'm not checking the exact minimal pieces necessary for
delegator-Grants. Instead, I'm starting a full implementation of the
person-side of Collab records (AKA direct-Grants), called Permit
records. This will also allow very convenient display of these Grants
and the extensions received through them, as well as UI buttons such as
accepting/rejecting a received Join or Invite.
Until now, adding a direct collaborator to a Project worked exactly like
with components: Invite or Join, then Accept, finally the direct-Grant.
I missed the fact that much like with project-component relationships,
projects (and teams) need to be able to send extension-Grants to their
direct collaborators.
So in Project's Grant handler it now:
- Recognizes the delegator-Grant coming from a new collaborator
- Sends extension-Grants, using the delegator-Grant as the capability
- When getting a new component and sending extension-Grants for it to
direct collaborators, Project uses their delegator-Grants as
capability
And in Project's Accept handler, it no longer sends extension-Grants
(because it doesn't yet have the collaborator's delegator-Grant at this
point).
NOTE, THIS TEMPORARILY BREAKS grant chains: If you create a Project and
add a Deck to it, you won't get an extension-Grant-for-the-Deck from the
Project, because the Project doesn't yet have your delegator-Grant.
The next commits will implement the Person-side of Collab records, and
will cause Person actors to automatically send the delegator-Grant,
fixing the break.
