1. Download yast-- project from https://github.com/yast/yast--

2. Follow the README to install the project.

Please fix this. Testing YaST-- and reproducing bugs must not require root privileges.

You need root privileges for 'sudo rake install', which is usual for any project.

3. YaST needs library files under YaST directory and with YaST-like name: link kerberos_client.rb (https://github.com/yast/yast--/blob/master/kerberos-client/kerberos_client.r...) to /usr/share/YaST2/modules/KerberosClient.rb

See above

This is workaround for another ruby-bindings bugs, as already mentioned:

But completely wrong for development and testing IMHO.

AFAIK it's for the D-BUS stuff which needs to be in correct directory. Anyway, it is sure that the project needs improvements on all parts, including configuration. That may be point of bugs against YaST++ project, but not of this one, which shows problems in ruby-bindings. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I discussed this bug with Jiri during the workshop. The reason it happens is because the bindings use Method#arity when it should probably use Method#parameters (as detailed in the ruby-doc).

The problem is arity being -1 for a 'varargs'-like parameter list. This is not handled properly by yast2-ruby-bindings.

Which is bug 705420. As a workaround, it should work to call KerberosClient::read () from example ycp code (without argument).

During the workshop Pepa and I found that it is trying to raise a SystemStackError. Ah, this would explain the TAG_RAISE

Looking into that, we found that there seems to be no particularly deep recursion. Maybe we are omitting some initialization step in the bindings.

I was comparing the initialization with the one from cmpi-bindings-ruby and couldn't find a difference. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
