Hi, I think I found a slight incompatibility between Ruby and YCP in YCP, I have the following code: map btrfs = GetTargetMap()["/dev/btrfs"]:$[]; map ret = filter( map p, btrfs["partitions"]:[], ``(p["uuid"]:""==uuid))[0]:$[]; which, in case of an empty list returned by filter call, relies on default parameter "$[]" after index operation. In RUby this is: btrfs = Ops.get(GetTargetMap(), "/dev/btrfs", {}) ret = Ops.get( Builtins.filter(Ops.get_list(btrfs, "partitions", [])) do |p| Ops.get_string(p, "uuid", "") == uuid end, 0, {} ) This works as before in assigning empty map to ret, but it now has the side effect of a line being written to y2log stating: [Ruby] yast/ops.rb:62 Index 0 is out of array size while the equivalent YCP code did not create any y2log entries. Is this intentional? Depending on the number of occurrences of such accesses in YCP code it could clutter y2log a lot.
