[Phpwebsite-developers] Good Feature to Consider [long]

[clayton c. <cc...@ca...>]

This is long, so bear with me ...

in my portal seeking travels, i ran across TerraCotta
(www.terracottasoftware.com) which provides basic infrastucture for
site-building. the docs make for good reading. they have a few very
interesting features (one of which is that you can automatically download
and install features from other terracotta sites - dont ask me about
security)

in any case one of the issues i was contemplating was one of module
dependencies (actually there are two levels of dependency, but i'll just
deal with one)

 lets say david d. developer creates a plugin which mails out notices when
concerts are added to the event calendar. well as it stands, we would have
to go in and modify the calendar code to accomodate this. also, if he wants
to give the 1000th registered member a free subscription to his dead-tree
magazine, he'd have to muck about in the code again. and what if he decides
to yank the calendar plugin ? well then youve got orphan DB entries to deal
with and your other plugins will crash and burn expecting to find something
that aint there.

one way to handle this is by Alerts ( TC's description and implementation
details at www.terracottasoftware.com/tc/doc/alerts ). basically you
register interest in events with a callback. when those events occur, your
code gets called. these "events" are stored in the database, and you can set
up a cron job to process them. they have urgency levels, so a low-disk quota
event would get handled before user registration event. They can also be
filtered.  so in our example the calendar module would call a raise_event()
function whenever someone added a new entry (events have associated data, so
you can store details). The registration module can raise an event when
someone registers.
  Alerts can get expensive, so we dont do them for very frequently occurring
events. Also for efficiency purposes, we can have an events_registered field
in the plugins table so that a plugin only needs to raise an event if
someone is interested.

<question to self>then again, can we manage all of this via cron? but this
way we have a greater level control which we can exercise via a web
interface</question>

just a thought...

BTW
PHPWeblog uses their html parser to screen user posts. it has a configurable
level of screening.
Their "Views" feature is an interesting take on block content handling. We
should probably look a this too.
