HE> The association provider was registered for each subclass with a HE> different name. That caused duplicated instances as the same HE> provider gets called twice, but has no chance to figure out for HE> which registration. It does, actually, if you use ASSOC_MATCH(). That was the little hack we used to prevent duplicate entries while enumerating a CIM_Foo class while we were not using connect_by_classname(). However, I think that using the classname connection to prevent duplicates is better. Some care may be required in associations that do not have to connect to libvirt. HE> This patch set tries to fix it. Please review. Thanks. I tested EAFP and it works for me. I'll move on to test the rest, but feedback from others would be good.
