GeneralRemoting: Unregistering Sponsors Pin
Heath Stewart2-May-03 3:17

I'm having a problem with an architectural issue and the MS newsgroups are too slow, so here's to hoping...

I have a licensing service (hosted by a Windows Service) that essentially uses the number of registered sponsors as the current number of licenses granted. This is done using signed XML, a unique ID (the computer's SID), and a number representing the number of licenses granted. The service - after having read and verified the license information - increments the granted license count with each registered sponsor and decrements the count when a sponsor unregisters*, where 0 <= n <= m, where n is the number of registered sponsors and m is the max number of licenses. If a client can't get a license, they're booted from the system (after a friendly error message).

* Now, the problem is that the only thing in the entire .NET Framework (I've searched all the extracted IL with regex's) that calls ILease::Unregister (where I would decrement the count) is ClientSponsor::Unregister. Nothing in the .NET Framework calls ClientSponsor::Unregister, however. This becomes a problem in any case because the server basically has to know when a sponsor is dropped, whether they've expired, quit, or have been unloaded unexpectedly (perhaps from Environment::Exit after a fatal error, or the OS crashes).

So, I must take the DCOM approach and poll the sponsor list that I keep track of (I implement my own ILease). This is not a unacceptable idea since this will all probably happen on a local network, but I would rather avoid it.

So, is there any way that the lease can know when a sponsor is dropped without GC? If the item is GC'd on the client, can I expect that the item in the list is GC'd eventually as well? I guess I'm just hoping for some ideas to solve this counter problem.

PS: The remoting interface is merely a marker. All the actual work is done by the lease/sponsor relationship since a Register/Unregister mechanism already exists.


Reminiscent of my younger years...
