Re: [libvirt] [PATCH v3 1/2] systemd: fix build without dbus

The virDBusMethodCall method has a DBusError as one of its parameters. If the caller wants to pass a non-NULL value for this, it immediately makes the calling code require DBus at build time. This has led to breakage of non-DBus builds several times. It is desirable that only the virdbus.c file should need WITH_DBUS conditionals, so we must ideally remove the DBusError parameter from the method. We can't simply raise a libvirt error, since the whole point of this parameter is to give the callers a way to check if the error is one they want to ignore, without having the logs polluted with an error message. So, we add a virErrorPtr parameter which the caller can then either ignore or raise using the new virReportErrorObject method. This new method is distinct from virSetError in that it ensures the logging hooks are run. Signed-off-by: Daniel P.
