y2log showed that the service was started but failed to register "org.opensuse.yast.SCR" with the D-Bus daemon. An 'rcdbus stop && rcdbus start' helped to circumvent the problem.

Let me guess, it could be a problem with DBus not reloading its config (reportedly a known bug) and thus not knowing that the process *is* allowed to own the service. In such a case, I use dbus-send --print-reply --system --dest=org.freedesktop.DBus / org.freedesktop.DBus.ReloadConfig (BTW that should go into "rcdbus reload" which currently does nothing) -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

2009-05-11 17:22:03 <3> d169(2273) [y2dbus] DBusConn.cc(connect):60 Cannot register service org.opensuse.yast.SCR: Rejected send message, 1 matched rules; type="method_call", sender=":1.39" (uid=0 pid=2271 comm="ruby ./check-setup.rb ") interface="org.freedesktop.DBus.Introspectable" member="Introspect" error name="(unset)" requested_reply=0 destination="org.opensuse.yast.SCR" (uid=0 pid=2273 comm="/usr/lib/YaST2/bin/SCR_dbus_server "))

Ugh, the error message does not make sense to me. It looks like a *consequence* of not being able to register the name, not the *cause*:

is reported by y2error("Cannot register service %s: %s", service.c_str(), dbus_error.message). So the Dbus error itself should be improved to contain more details. Yast could just log a suggestion what to do (Dbus reload) to y2log.

I guess it's not possible to pass any error code back when the connection fails, the reply cannot be sent without a DBus connection.

Note that we do have a connection, we just could not register the service name. In dbus sources, bus/activation.c, handle_activation_exit_error, there does not seem to be a way to pass an error message. If we really really wanted that, we could have the service send the error via a signal on the interface o.o.y.FamousLastWords OTOH, I hope such errors only occur with improper installation during development, so the customers, having a proper RPM, will never see them[TM]. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

y2log showed that the service was started but failed to register "org.opensuse.yast.SCR" with the D-Bus daemon. An 'rcdbus stop && rcdbus start' helped to circumvent the problem.

Let me guess, it could be a problem with DBus not reloading its config (reportedly a known bug) and thus not knowing that the process *is* allowed to own the service.

Maybe. But doesn't the process get an EACCESS error (or similar) back then and can report the fact ? Just exiting doesn't seem right.

In such a case, I use

dbus-send --print-reply --system --dest=org.freedesktop.DBus / org.freedesktop.DBus.ReloadConfig

(BTW that should go into "rcdbus reload" which currently does nothing)

Right, that seems to be the culprit. So for now, yast2-core needs above dbus-send in its %post. Once "rcdbus reload" is fixed, yast2-core must call 'rcdbus reload" in its %post. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

So where is the bug? YaST or DBus. I as current yast-maintainers handler don't know.

Both IMHO. yast2-core needs to - improve the error message in y2log - call "dbus-send ..." in its %post dbus needs to - make "rcdbus reload" work properly. -- Configure bugmail: http://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

yast2-core needs to - call "dbus-send ..." in its %post

Done in yast2-dbus-server-2.18.1 (in YaST:Head).

- improve the error message in y2log
