- Update on branch-renaming
- Move from actor stack to transactions (Tamsin)
- Problem statement: The actor stack has a number of conceptual, architectural, and implementation problems.
- Interprets user input (perhaps more of a controller problem)
- Handles validation (perhaps more of a form/controller problem)
- Persists objects with transactions (though not very well)
- It implementation is dependent on Rails::Rack::Middleware, which is an odd creature; Which has design decisions for multi-threaded servers. For our ActorStack, this creates some fussy state dependencies. The Actors are all in the pool, which means instance level state is visible across multiple requests. This can create data pollution.
- Tamsin has worked to disentangle the three conceptual concerns. Some work exists in lib/transactions; These will be deprecated in 4.0. We're now pushing to use Dry::Transactions in Valkyrie space. The proposal is:
- There's a ChangeSetForm which replaces Hyrax::WorkForm and its objects; This leans on the extensively adopted and vetted Reform gem. Moving interpretation of user input to this.
- We pass the ChangeSet to the Transaction which negotiates the app needs, change set validation.
- There is a bunch of work that happens when an actor finishes its initial persistence of the work
- Some of these steps might be further steps in the transaction
- Some may be deferred to the pub/sub class; This is builds on the old Hyrax callbacks implementation (from 2015). It provides global callback methods. We're replacing this with Dry::Events. The old callback methods now publish events on the Dry::Events bus. You can see these in Hyrax:

- Some of the existing Actor Stack behavior has been extracted into these listeners. We're deprecating and removing these from the default stack. The logic is now in a listener.
- Problem statement: The actor stack has a number of conceptual, architectural, and implementation problems.
