bovine/bovine_process

bovine_process

bovine_process consists of the side effect logic of Activity objects. This means it contains the code, the logic that for an incoming object, one executes:

• Store object in bovine_store
• Add reference to inbox
• Perform side effects
• Enque object for bovine_pubsub

And a similar list of effects for outgoing objects, i.e

• Store object in bovine_store
• Add reference to outbox
• Perform side effects
• Send objects to follower's inbox
• Enque object for bovine_pubsub

The behavior defined in this package corresponds to 6. Client to Server Interactions and 7. Server to Server Interactions of the ActivityPub specification. However, only a small subset of side effects is implemented.

Implemented Side Effects

• Create, Update, Delete. Deletes are handled by replacing the object with a Tombstone. Various checks are performed to ensure only appropriate Updates happen.
• Specify Update checks
• Follow and Accept
  • Outgoing Accept of Follow adds to followers
  • Incoming Accept of Follows adds to following
• Implement other side effects, in particular Like, Announce, and inReplyTo
• Authority checks.

That's it. Currently, no collections for replies and likes are kept in bovine_store, so implementing these side effects cannot happen yet:

• Announce -> add to share collection
• Like -> add to likes collection
• Create with inReplyTo -> add to replies collection

Tests

The folder tests/data contains test cases what side effects happen in the database for certain cases.
