[geeklog-devel] Gsoc Notification service

[ganesh]

Hi
I found a pear package on event-dispatcher based on the Observer pattern
http://pear.php.net/package/Event_Dispatcher
I also stumbled upon a sig-slot like implementation for php which might be
useful but its more-or less skeletal
http://www.phpclasses.org/browse/package/3624.html

If a similar sig-slot were to abstracted for the GL core which be extended
(in the php sense of it!) by the plug-ins, wouldn't plug-in development  be
easier? Like if an abstracted signal class with the following props like :
______________________________________
SIGNAL
->UTC  ; when generated
->Level ; Security level to it
->Code ; a unique code to it
->Who ; source , could be none for automated signals
____________________________________________
Slots
 ->cleanup ; when action to be taken
->action ; handle to function to be activated
->logStorePath ; this will refer to the place where the cleaned-up
notifications will be logged in files for future reference
->Code ; The code identifying the signal

When we have a plugin extending these , would it cause any security
problems??

I found the discussion on email handling and throttling in gsoc 2k8 on
notification service
http://eight.pairlist.net/pipermail/geeklog-devel/2008-March/003290.html
Well if GL were to put in place restrictions like frequency of signals
granted a slot on time basis ,would it still bear any other problem ?

Also for notification would something like bottom tool-bar using dojo/jQuery
to indicate the current notifications be good idea ?

tnx
