in thread RFC: Subscription to nodes
I haven't looked at a line of the PM code, so please tell me to shut up when I go out of line.
Let's change subscription to watching. What about the following design:
- Every node knows about its parent.
- Every node would have a list of watchers associated with it. This list would be taken from the Personal Nodelet of each Monk.
- If a reply is made to a node, all watchers would have their personal nodelet updated to have an asterisk (or similar notification) put to it. Basically, a flag would be set in the Personal Nodelet table for each monk.
- The watching of a post and its descendents would be implemented by having a user be a watcher on every single post. And, when a reply is made, that monk would become a watcher on the new post automagically. The trick is to make sure that the right spot in the Personal Nodelet is updated.
- So, you could do the following table:
And, if a reply is made to that node, then that Nodelet_Id is updated. If the Node_Id != the Nodelet_Id, then the monk must be watching the whole thread, so add that monk to the new node's Thread_Watching entries.Thread_Watching --------------- Node_Id Monk_Id Nodelet_Id
I have no idea how much work that would take, and I can't provide a huge amount of coding help (4 kids), but I'll help as much as I can ...
