[Rpm-maint] [rpm-software-management/rpm] Notify other programs when the rpmdb is changed via DBus (#1249)

[Florian Festi]

Well, DBus is not the same as DBus. There are two things you can do there:
This thing here is just sending signals. They go to the bus and are then relayed to everyone subscribing to them. I don't know that much about DBus but I would hope sending a few thousands signals shouldn't hurt anyone. By design there is no way for 3rd party processes to talk back to rpm. They either listen or they don't. This also means we need to send everything we think anyone might need.
Offering an RPM interface on DBus is a very different thing. This either needs some daemon or some bus-activated service - which is basically also a daemon. This allows users to basically do remote procedure calls to this daemon and get data back as a result. The DBus actually supports a tree like structure for making objects available and has some build in introspection interface. If we really want to add something like this we should probably talk to the DNF folks who are working on a daemon on their own.
