AggregateRoot::AutoConflictResolution about rails_event_store

[paneq]

BTW

module AutoConflictResolution
  def store(stream_name = loaded_from_stream_name, event_store: default_event_store)
    super
  rescue
    unpublished_events = unpublished_events()
    tried_version = version
    self.load(stream_name, event_store: event_store)
    published_events = loaded_events[tried_version+1..version]
    if not_conflicting(unpublished_events, published_events)
      @unpublished_events = unpublished_events
      store(stream_name: stream_name, event_store: event_store)
    end
  end
end

class OrderWithNonConflictingStore < Order
  include AutoConflictResolution
  private

  def not_conflicting(unpublished_events, published_events)
    true
  end
end

This part :

published_events = loaded_events[tried_version+1..version]

could be optimized better to use RES to read all events on position >= tried_version+1 instead of reading all events again and selecting from array those conflicting ones.

But that's just a performance optimization.
