The APIC POST handler unconditionally stamped status:"created" on every
write with no comparison to stored state. cisco.aci.aci_rest derives its
"changed" result from a recursive deep-scan of the response for any status
in {created,modified,deleted}, so every raw aci_rest-driven write reported
changed=true forever — breaking pass2 idempotency across the L3Out topology
(l3extLNodeP/l3extLIfP/l3extRsNodeL3OutAtt/l3extRsPathL3OutAtt/bgpPeerP/
bfdIfP), static-path, and PBR-redirect blocks.
F8a computes a real per-MO status at the write choke point
(writes._upsert_recursive) by diffing ONLY the caller's raw posted attrs
(excluding dn/status, before the create-time _CLASS_DEFAULTS overlay)
against the pre-existing stored MO. apply() builds imdata from only the
changed MOs — empty imdata (+ totalCount "0") when nothing changed, which is
the shape that makes aci_rest's changed()-scan return false. post_mo reads
?rsp-subtree and threads it through (modified/absent/full -> changed list;
no -> empty). Higher-level cisco.aci modules were already idempotent
(client-side get-diff) and are unaffected. The flat changed-MO response is
changed()-scan faithful; real APIC's nested rsp-subtree wire shape is a
documented deferred enhancement (no real-gear capture to reproduce it).
F1 fold-in: deleting an already-absent DN now reports unchanged (store pop
is a silent no-op) instead of deleted, matching real-APIC idempotent delete.
Verification: full pytest 1143 passed (1131 baseline + 12 new F8a tests,
zero regressions); independent opus review traced the posted-keys-only /
pre-defaults diff invariant + dict-aliasing safety to ground truth
(APPROVE); live E2E gate on the restarted sim — create_tenant SF-TN1 pass2
changed 6->0 (idempotent), pass1 still builds (changed=17), F10 bad-mtu 400
+ good-mtu 200 intact.
