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:
    Thread_Watching --------------- Node_Id Monk_Id Nodelet_Id
    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.

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 ...

The idea is a little like C++ templates, except not quite so brain-meltingly complicated. -- TheDamian, Exegesis 6

Please remember that I'm crufty and crochety. All opinions are purely mine and all code is untested, unless otherwise specified.

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
    a, abbr, b, big, blockquote, br, caption, center, col, colgroup, dd, del, div, dl, dt, em, font, h1, h2, h3, h4, h5, h6, hr, i, ins, li, ol, p, pre, readmore, small, span, spoiler, strike, strong, sub, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, wbr
  • You may need to use entities for some characters, as follows. (Exception: Within code tags, you can put the characters literally.)
            For:     Use:
    & &amp;
    < &lt;
