Module node_ops 

Node-expression resolution: parsing hostlist strings, NID-to-xname translation, HSM-group expansion, and the authorization helpers that validate the caller can act on the resolved set.

Functions

from_hosts_expression_to_xname_vec

Translates a ‘host expression’ into a list of xnames.

from_user_hosts_expression_to_xname_vec

Convenience wrapper that fetches node metadata from the backend and resolves a hosts expression to a sorted, deduplicated list of xnames.

get_curated_group_from_xname_hostlist

Group the supplied xnames by their parent HSM group.

get_xname_from_nid_hostlist

Resolve a NID hostlist expression to xnames by cross-referencing available node metadata.

get_xname_from_xname_hostlist

Filter available node metadata to only those xnames present in node_vec.

resolve_target_nodes

Resolve target nodes from either a hosts expression, an explicit HSM group name, or the settings-level HSM group.
