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.
deckResolve now supports Resolve requests that use extension-Grants. It
iterates the verifies the Grant-chain using the process described in the
ForgeFed specification.
Vervis currently supports only direct grants. The new process supports
delegation chains as well. This commit just implements the new process
as a new function, without yet using it anywhere. The next commits will
plug it into Deck actor handlers.
Ticket closing can now be done via the new C2S, and the "Close ticket"
button on TicketR page is back, and uses that new C2S.
S2S, C2S and pseudo-client are implemented for both Deck and Loom, but
the actual button and POST handler are provided here only for Deck. Will
add ones for Loom soon, as needed.
This is to allow getting rid of the old C2S offerTicketC and write a C2S
Offer handler in the new actor system.
And that is to allow ticket opening and closing to work, so that it can
use delegated OCAPs too, as a first demo of delegated OCAPs in action.
