* fix(model-management): honor an explicit null as a clear on model update
PATCH /model/{model_id}/update merged the patch with exclude_none and then
popped explicit nulls only for the mirrored pricing fields, so a null sent for
max_input_tokens, mode, supports_vision or any other key was dropped and a value
pinned by an earlier save could never be removed.
The route now follows JSON Merge Patch over both blobs: a key absent from the
body is unchanged, a key sent as null is removed from the stored row, and a key
sent with a value is set. Ownership and identity keys keep ignoring a null, as
do the fields the stored models require, since clearing one writes a row no
reload can rebuild. Mirrored pricing keys still clear from both blobs.
Clearing a price also needed the router to stop merging a deployment's cost-map
entry onto its previous registration, which left the old rate in place and kept
billing at a price the deployment no longer carried.
Adds a create, read, partial-update, clear, enforce, delete lifecycle e2e that
reads back on every replica, and a harness helper for that read-back.
* fix(router): keep a deployment id that names a real model from evicting its catalog entry
Deployments are keyed into litellm.model_cost alongside the built-in catalog, so
evicting a deployment's stale entry by id could take a real model's entry with it:
registering a deployment whose model_info.id is "gpt-4o" stripped that model's
pricing, context window and capability flags process-wide, for every other
deployment of it, until the next price-map reload.
Only evict an entry this registration owns. A colliding id keeps the previous
merge, which pollutes the catalog entry rather than emptying it.
Also pins the Admin UI round trip: the model edit form echoes the whole /model/info
row back on save, and that read reports every key the deployment never stored as an
explicit null, so the clear path has to leave those keys alone.
* fix(router): decide cost-map eviction by what this registrar created
The previous guard read a catalog entry off `litellm_provider`, so a deployment
that declares its own provider in model_info was treated as one and kept billing
at a price it no longer carried. It also only held for a single registration: a
second one under a colliding id saw the id the first merge left behind and
evicted the catalog entry anyway.
Track the cost-map keys this registrar creates instead. A key it created is
evicted before re-registration; one it did not is left to merge, which is what a
deployment id colliding with a catalog model name needs.
Also folds the required-fields comment into the docstring that already gives the
reason.
* fix(router): release a deployment's cost-map key when it is deleted
The ownership ledger only grew. A deleted deployment kept its claim, so if a
later catalog refresh started publishing a model under that same name, the next
registration would treat the catalog entry as the deployment's own and evict it.
Deleting a deployment now gives the key back, which also stops the ledger
growing for the life of the process.
* fix(router): hold a cost-map key while another live router still serves it
The claim is process-wide but the release was per-deletion, so with two routers
serving one deployment id, the first deletion put the survivor back on merging
and the price it had just cleared would keep billing.
Release the key only once no live router still serves that id.
* fix(router): register a router in the live set when it gains a deployment
_live_routers was only joined when a router was constructed with a model_list,
but a router built empty is populated through add_deployment, and the empty
branch exists for exactly that. Such a router was invisible to the live-router
scan, so deleting the deployment from another router released the shared
cost-map key while it was still serving that id.
Joining the set where a deployment enters the list covers every path, and it
also lets a price reload rebuild what a dynamically built router serves.
* fix(e2e): read the stored model row from the control plane, not each gateway
The lifecycle suite polled /model/info on every URL in PROXY_REPLICA_URLS. Those
URLs are the stack's gateways, and gateway/routes/allowlist.py trims them to the
LLM data-plane surface, so /model/info answers only on the backend and 404s on
every replica. All five tests failed at their first read-back in CI while passing
against a monolith, where one process serves both planes.
The stored row has one answer behind it, so it is read through the shared
transport, which routes control-plane paths to the backend. What every gateway
must agree on is which models it serves, so the create and delete steps poll
/v1/models per replica instead, a route the gateway does serve.
read_back_everywhere now rejects a control-plane path outright rather than
timing out on it.
Two things surfaced behind that. /public/ was missing from the transport's
control-plane prefixes, so model_cost_map() was routed to a gateway and 404'd,
and the billing steps needed a data-plane wait: a PATCH lands on the backend and
each gateway picks it up on its own config reload, measured here at 12-24s, so
they now drive calls until the new rate reaches the spend row and let the
deadline fail them.
