[OpenSIPS-Devel] Fwd: [RLS] Cannot found service uri in rls-services

I forward this mail with an attached fix for the issue I encountered.
It enables the service lookup to include parameters from the URI.
So the RLS now respond with a 200OK to the subscribe request for a
parametized service uri.

But I'm still stuck because the service node parser doesn't handle
resource-list tag in the service node so the RLS doesn't expand
subscription...
This could be fixed inside notify.c:process_list_and_exec

Eric.

After a look at modules/rls/subcribe.c from trunk, I found line 557 :
        if(uandd_to_uri(msg->parsed_uri.user, msg->parsed_uri.host,
                    &subs.pres_uri)< 0)

then, line 566 :
        if( get_resource_list(&subs.pres_uri, fu.user, fu.host,
                    &service_node, &doc) < 0)

In my memory, the pres_uri should include the parameters.

Eric.
