Yes, that could be possible. But I would rather prefer some kind of template or config file provided by developers which would be converted to a PolicyKit config file.

We need some way to tell users of the service which Yast modules and methods they can use via DBus. Simply, what we support.

I think that defining a PolicyKit config should mean that all functions defined there are supposed to be used via DBus.

Now you can use any Yast module via DBus, the DBus service can export all public functions. The problem is that the modules were not designed for multiple parallel access, there might be race conditions between clients due to state full API or the API might not be suitable for DBus access (too big/complicated data structures) or the module is internal and should not be used from outside at all...

• The main problem while using SCR:execute in combination with the YaST

command line interface is the speed. Have you already tested how long it takes to e.g. add a user or get a list of local users ?

No, not yet. But Klaus wrote a testing ruby script - test_SCR_dbus_server.rb in core/dbus/SCR_service. We could reuse it for benchmarking.

The main problem is that the Yast modules were not designed for DBus/Web usage. E.g. getting complete user data might take very long time for several thousands users.

In such case we should redesign the API - return just subset of the users. The Web UI would just read first 100 users. Next 100 users would be read after pressing [2] or [Next]. Or there should be [Search] button...

This is another reason for explicitly marking functions as DBus enabled.

Hi all,

I'd like to announce the Yast DBus service which is now available in SVN Trunk and in FACTORY. You just need to install yast2-core-2.18.7 package [*].

The new service can export every Yast name space, even non YCP modules like Users (Perl) or Pkg:: (C++).

This service should be used as the base component for our new Yast Web interface.

For more information look at http://en.opensuse.org/YaST/DBus_Service/Description

I'm looking forward to your feed back.

Ladislav, can you show us a more concrete example?

For example, I want to enable the firewall, and open port 8080, using dbus.

1. what would be the policykit policies for this
2. what would I need to call via dbus?

One nice example is here:
