Re: [Libvirt-cim] [PATCH] Fix VSMS instance code to refuse to return an instance if ref is invalid

DS> +static int compare_prop(const CMPIObjectPath *ref, DS> + const CMPIInstance *inst, DS> + const char *name, DS> + int mandatory) DS> +{ DS> + char *prop = NULL; DS> + char *key = NULL; DS> + int rc = 0; DS> + DS> + key = cu_get_str_path(ref, name); DS> + if (key == NULL) { DS> + rc = !mandatory; DS> + goto out; DS> + } DS> + DS> + if (cu_get_str_prop(inst, name, &prop) != CMPI_RC_OK) DS> + goto out; DS> + DS> + rc = STREQ(key, prop); DS> + out: DS> + free(prop); DS> + free(key); DS> + DS> + return rc; DS> +} I think that some variation of the above function probably deserves to be in libcmpiutil. The act of comparing an instance with a reference and make sure that all keys are either correct or unspecified seems like a common thing. There are probably other places where we need such a filter anyway. Thoughts?
