crmsh/xmlutil.py:328

• [nitpick] The function name is_normal_node is now misleading since it no longer considers the 'normal' node type; consider renaming the function or updating its documentation to reflect that it only checks for 'member' nodes.

return n.tag == "node" and (n.get("type") in (None, "member", ""))

crmsh/ra.py:107

• The removal of the fallback branch in the ra_meta function may lead to missing metadata if crm_resource fails; verify that crm_resource reliably returns valid metadata in all environments or consider retaining a fallback mechanism.

return crm_resource("--show-metadata %s:%s" % (ra_class, ra_type))
