Hi everyone, I have started laying the foundations for a new 'box' for Kannel which intends to allow users more flexibility in terms of the platform.
At the moment there are many ways to get messages into the bearerbox, namely: smsbox, wapbox, opensmppbox, smppbox, ksmppd, sqlbox. Some rely on routing in their own process and others allow bearerbox to do the routing. What they all have in common is they don't allow external or third party applications help make decisions at processing time (with the exception of ksmppd/smppbox). My new planned box is called pluginbox which will basically be like SQLBox - but instead of using database callbacks, it will allow linking of dynamic libraries (.so|.dylib) which will allow custom interception/filtering/modification of message packages to and from various boxes. So a hypothetical scenario for this box could be something like SMSBox, SMPPBox/KSMPPD, WapBox <--> PluginBox <--> Bearerbox Or even SMSBox, SMPPBox/KSMPPD, WapBox <--> SQLBox <--> PluginBox <--> Bearerbox For those who want to still make use of SQLBox. My initial design is to use an asynchronous callback chain to allow slow plugins to not hold up the processing of faster messages. This would be especially useful in the context of people using HTTP and other external services to process routing decisions. The plugin would also be able to return a status to 'reject' a message packet which would in turn not submit to the target receiver. My plan is also to implement at least one example plugin (probably an HTTP plugin?) which can show the submission and manipulation of a message packet in both directions. So here I am looking for comments. 1) Is this something worthwhile doing, does anyone else have a need for this? 2) Are there any considerations you wish to add at this time? 3) Are there any features you would like to see added? 4) Would there be any problem including this in the Kannel repository? Here is the initial version : https://github.com/donald-jackson/kannel-pluginbox Thanks Alejandro for SQLBox, its largely based on your code. Regards, -- Donald Jackson http://www.ddj.co.za
