Hey,

One more thing, I would really appreciate if you can share any thoughts around the code restructuring you have mentioned in your earlier reply. If that’s something that’s not going to take in a lot of your time.

Don’t want to take up a completely orthogonal approach or reinvent something.

Thanks for the prompt reply Fabian. Yes, from the cursory look it does look like it will take some effort to handle all the threads and the queues to handle dynamic config. I Will try to attempt it myself in pieces, maybe support adding/deleting servers first and then look at clients and so on. Will share my progress with the forum.

Hi Imtiyaz,

Greetings ! I am looking at a usecase wherein we want radsecproxy to

handle config changes on the fly instead of having to restart the whole process. For example, say we add/del new radius servers or clients without affecting the existing sessions/threads.

As I am comparing a few design choices to make this happen, wanted to

check if someone has already worked on it ? If it is in roadmap for the immediate future, any design concepts someone might have already thought of but were not able to implement it ?

This is on my personal wish-list, but I haven't done any work in that direction. I think it will require quite a lot of restructuring, as right now, most of the code isn't prepared for dynamic config changes (apart from the dyndisc stuff). I do want to do this some day, but I think there are more important features right now.

Regards, Fabian

Thanks Fabian. Sounds like a good plan indeed. I am giving this a shot, let's see how that goes.

The structure I once imagined was to modularize the code (maybe roughly along the config blocks), and separate it from the config interpreter. Then have a central core configuring multiple instances of each module and stitching them together. This should also simplify unit testing for each module.
