LocalAI [bot]	07f6c15a37	feat(ds4): layer-split distributed inference (#10098) ... * feat(ds4): add standalone ds4-worker distributed worker binary Add worker_main.c, a minimal standalone worker that owns a slice of the model's transformer layers and serves activations over ds4's own TCP transport via ds4_dist_run(). It links the same engine objects the backend already builds (including ds4_distributed.o) and has NO gRPC/protobuf dependency, so it builds even on hosts lacking protobuf/grpc dev headers. Launched by `local-ai worker ds4-distributed`. Wire the ds4-worker CMake target (mirrors grpc-server's object/GPU/native handling) and have the Makefile copy + clean the binary alongside grpc-server. Ignore the built ds4-worker artifact. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> Assisted-by: Claude:claude-opus-4-8 [Claude Code] * feat(ds4): package ds4-worker alongside grpc-server Copy the standalone ds4-worker binary into the backend package (Linux package.sh) and the Darwin OCI tar (ds4-darwin.sh: both the explicit copy and the otool dylib-bundling loop) so distributed workers ship with the backend.

Distributed inference is an engine backend: when LoadModel receives 'ds4_role:coordinator', the process populates ds4_engine_options.distributed (role, layer slice, listen host/port) before ds4_engine_open, then the normal ds4_session_* generation path runs transparently once the worker route covers all layers. - New LoadModel options: ds4_role, ds4_layers (START:END or START:output), ds4_listen (host:port), ds4_route_timeout. - parse_layers_spec() maps the layer spec onto ds4_distributed_layers. - wait_route_ready() blocks generation until ds4_session_distributed_route_ready() reports full coverage (or timeout), gating both Predict and PredictStream; returns UNAVAILABLE on timeout/error. - No ds4_role => g_distributed stays false and wait_route_ready is a no-op, so single-node behavior is unchanged.

Unlike worker_llamacpp.go, ds4 bundles its own dynamic loader (lib/ld.so) for glibc compatibility, so when present we exec ds4-worker through that loader with LD_LIBRARY_PATH=<backend>/lib, mirroring backend/cpp/ds4/run.sh; otherwise we exec it directly. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> Assisted-by: Claude:claude-opus-4-8 [Claude Code] * feat(cli): register the ds4-distributed worker subcommand Wire DS4Distributed into the Worker kong command tree so `local-ai worker ds4-distributed` is available. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> Assisted-by: Claude:claude-opus-4-8 [Claude Code] * docs(ds4): document layer-split distributed inference Add a ds4 section to the distributed-mode feature docs (coordinator model YAML, manual worker command, layer-range semantics, the 'GGUF on every machine' requirement, coordinator-listens dial direction vs llama.cpp) and a terse Distributed mode section to the ds4 backend agent guide. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> Assisted-by: Claude:claude-opus-4-8 [Claude Code] * test(ds4): opt-in hardware-gated distributed e2e spec Add a self-contained, opt-in Ginkgo spec to the backend e2e suite that spins a ds4 coordinator (via the packaged run.sh, loaded with ds4_role/ds4_layers/ds4_listen options) plus a ds4-worker process for the upper layers, then uses Eventually to assert a short successful Predict once the layer route forms, before tearing the worker down. Gated by BACKEND_TEST_DS4_DISTRIBUTED=1 (plus the existing BACKEND_BINARY + BACKEND_TEST_MODEL_FILE and optional layer/listen/accel knobs); compiles and skips cleanly with no env, hardware, or model.

The nvcc-built ds4_cuda.o (and Obj-C++ ds4_metal.o) reference the C++ runtime, so the CUDA/Metal builds failed with undefined libstdc++ symbols (std::__throw_length_error). The CPU build passed because ds4_cpu.o is pure C. Force LINKER_LANGUAGE CXX so libstdc++ is linked.

Previously evictOldestLocked cleared a victim's value but never removed the now value-less node or its childless ancestors, so internal nodes accumulated under sustained churn at the cap. The MaxEntries path now prunes the victim and its empty ancestors. - DRY: pruneWalk replaces the duplicated logic in the former pruneLocked and Remove's inner closure. - Switch Tree.mu to sync.RWMutex; LongestMatch, Weight and Len take the read lock (RLock) while Insert, Evict and Remove keep the write lock. Confirmed race-clean under go test -race. - Document the strict greater-than TTL boundary on Options.TTL and expired: age exactly equal to TTL is still live. - Guard Insert against an empty key (no-op): the root never holds a value. Adds Ginkgo specs covering MaxEntries eviction, ancestor reclamation, the no-growth-past-cap invariant, the TTL boundary, and empty-key behavior for both Insert and LongestMatch.

Correctness: ExtractChain now chunks from absolute offset 0 with fixed [0,W),[W,2W),... boundaries and caps the chain to the FIRST MaxDepth head blocks. The previous tail-keeping logic shifted the byte offset by a non-window amount once a conversation grew past MaxDepth*WindowBytes, changing every hash each turn and silently breaking cross-turn longest-prefix matching. The reusable KV/prefix cache lives at the head of the prompt, so anchoring at offset 0 makes the chain a true prefix-chain: P and P+suffix share their full leading overlap. Add a regression spec proving cross-turn stability past the cap. Performance: Index.Decide precomputes each candidate's Weight once (decorate-sort-undecorate) instead of calling the O(tree size) Weight inside the O(n log n) sort comparator. Behavior is unchanged. Lint: encode prev with binary.LittleEndian.PutUint64 instead of a manual byte loop, clearing the modernize rangeint finding. Also add a concurrent Decide/Observe/Invalidate spec to exercise Index's documented concurrency safety under go test -race.

Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(nodes): optional route preference in FindAndLockNodeWithModel Add a RoutePreference type and a new pref parameter so the atomic pick+lock+increment can be biased toward a preferred node without weakening atomicity. A nil preference reproduces the previous ORDER BY behavior exactly. Update the ModelRouter interface, both router.go call sites (pass nil for now; Phase 5 builds the real preference), the test doubles, and the distributed e2e caller. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(prefixcache): make Sync satisfy Provider with Evict Sync.Observe now returns whether the local index treated the assignment as new or extended, and Sync gains an Evict method that delegates to the wrapped index. Together these let SmartRouter hold a single prefixcache.Provider that broadcasts via NATS. Adds a compile-time Provider assertion and an Evict-delegates behavioral test. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(nodes): prefix-cache-aware preference and observe in SmartRouter.Route Add a PrefixProvider + PrefixConfig to SmartRouterOptions/SmartRouter (nil keeps routing byte-for-byte the round-robin floor). On each request Route now calls buildPreference: it reads the prompt prefix chain from ctx (distributedhdr.PrefixChain), resolves the per-model policy/thresholds over the global config, loads candidate replica in-flight via a new registry read LoadedReplicaStats (deduped to one entry per node using the MIN in-flight across that node's replicas), asks the provider to Decide, and runs prefixcache.Select. The chosen node is passed as the RoutePreference to FindAndLockNodeWithModel on all three pick paths (cache hit, locked re-pick, cold scheduleAndLoad), and the served node is recorded via Observe only when the resolved policy is prefix_cache so round-robin models never pollute the tree. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(nodes): invalidate prefix-cache entries on unload and stale removal UnloadModel and both staleness fall-through paths in Route (after a failed gRPC probe and RemoveNodeModel) now call prefixProvider.Invalidate(model, nodeID), guarded by a nil-provider check so the round-robin floor is unchanged. At runtime the provider is the *prefixcache.Sync, so invalidations also broadcast to peer frontends. Adds a test that a previously hot prefix no longer Decides to a node after UnloadModel. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(prefixcache): rolling forced-disturb pressure counter Add a concurrency-safe per-model rolling counter that tracks how many times a request had a usable hot prefix match but the load guard forced it off the warm node. Entries outside the window are dropped lazily on Count so the backing slice stays bounded. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(nodes): autoscale on prefix-cache forced-disturb pressure Wire the rolling forced-disturb counter into the SmartRouter and the ReplicaReconciler. Router: in buildPreference, after Decide + Select, record a forced-disturb when a usable hot prefix match existed (d.HotNodeID != "" and d.MatchRatio >= cfg.MinPrefixMatch) but Select chose a different node (or nothing) because the load guard ruled the warm node out. This is the scale-worthy signal: the cache-warm replica is saturated. It deliberately does not fire for all-unique workloads (no hot match), avoiding false-positive scale-ups. Pressure is optional on SmartRouterOptions; nil keeps the path a no-op. Reconciler: read the same Pressure instance in reconcileModel as an extra scale-up reason, reusing the existing MaxReplicas + ClusterCapacityForModel guards and the UnsatisfiableUntil cooldown that gates the whole method. Pressure never overrides MaxReplicas and never force-evicts; a no-capacity model does not spin. Window and threshold come from prefixcache.Config (PressureWindow default 1m, PressureScaleThreshold default 1) and are configurable via ReplicaReconcilerOptions. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(prefixcache): bound Pressure slice in Record; drop dead reconciler pressureWindow Record now prunes entries older than the rolling window (the same prune Count does), via a shared pruneLocked helper, so a model that takes forced-disturb records but is never Counted (e.g. one with zero loaded replicas the reconciler skips) no longer grows its backing slice unbounded. Also removes the dead pressureWindow struct field and the ReplicaReconcilerOptions.PressureWindow option from the reconciler: they were stored but never read (the window lives inside the *prefixcache.Pressure instance). The scale block now reads pressure.Count once into a local. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(api): prefix-cache fields in scheduling endpoint DTO with validation Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(ui): prefix-cache routing controls in node scheduling form Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(distributed): wire prefix-cache index, NATS sync, and config Activates prefix-cache-aware routing in distributed mode. Builds the prefixcache Index + NATS-backed Sync + Pressure counter, installs the distributedhdr.PrefixChainHook so core/backend/llm.go attaches a prefix chain per request, subscribes to prefixcache.observe/prefixcache.invalidate to apply peers' events to the local index (no re-broadcast), threads PrefixProvider/PrefixConfig/Pressure into the SmartRouter and Pressure/PressureThreshold into the ReplicaReconciler, and runs a background eviction ticker (every TTL/2) bound to the app context. Enabled by default; --distributed-prefix-cache=false (LOCALAI_DISTRIBUTED_PREFIX_CACHE) opts out and leaves the provider/pressure nil so routing stays round-robin. --distributed-prefix-cache-ttl (LOCALAI_DISTRIBUTED_PREFIX_CACHE_TTL, default 5m) controls entry idle-timeout and eviction cadence. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * test(nodes): round-robin-floor invariant for prefix-cache routing Drives Select directly: a saturated hot node (in_flight 50 vs 0) is never picked even with a perfect prefix match (round-robin floor holds), while a balanced hot node within the load slack is reused. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * chore(prefixcache): clear branch lint findings and em dashes Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(distributed): validate prefix-cache config at startup wiring Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * perf(radixtree): single-walk WeightsFor for batch value weights Add Tree.WeightsFor(values, now) which computes the recency-weighted weight for many values in a single O(N + len(values)) tree traversal, versus calling Weight once per value (O(len(values) * N)). Consumers that score K candidates against the tree under the read lock no longer pay K full walks. Extract the per-entry contribution math into an unexported helper shared by both Weight and WeightsFor so the metric stays identical (DRY). Weight's public behavior is unchanged. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * refactor(config): add ModelConfig.ModelID() single source of truth The c.Name fallback to c.Model was duplicated in core/backend/options.go (feeding model.WithModelID) and hand-copied into core/backend/llm.go (the prefix-chain salt). These MUST agree or the prefix-cache salt diverges silently from the id the model loader tracks. Consolidate both into a new config.ModelConfig.ModelID() helper and call it from both sites. Behavior is identical. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * perf(prefixcache): reuse one xxhash.Digest in ExtractChain ExtractChain allocated a fresh xxhash.New() Digest per block (up to MaxDepth per call) and grew the chain slice without preallocation. Reuse a single Digest via Reset() before each block and preallocate the chain to min(nBlocks, MaxDepth). xxhash seed 0 is stateless, so Reset()+Write produces the byte-identical value to a fresh New()+Write. Output hashes are unchanged, preserving the cross-process determinism that peers rely on over NATS. Verified by capturing ExtractChain output for the existing test inputs before and after the refactor: identical. Existing extractor tests pass unchanged. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(prefixcache): drop hot match when matched node is not a candidate; weigh cold candidates in one walk Index.Decide called radixtree.LongestMatch over the whole tree, so the deepest match could be a node that is offline, unloaded, or simply not in the passed candidate set. Honoring that as HotNodeID produced a false forced-disturb signal upstream (buildPreference records pressure when chosen != HotNodeID), making it look like a warm replica was load saturated when it was actually absent. Build the candidate set once and only set HotNodeID/MatchRatio when the matched node is an actual candidate; otherwise fall back to cold placement. A future refinement could ask the tree for the longest match restricted to the candidate nodes (shallower-but-valid) instead of dropping it. Also replace the per-candidate tree.Weight call in the cold-order sort with a single tree.WeightsFor walk, turning O(K*N) under the read lock into O(N + K). Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * refactor(prefixcache): remove Select's unreachable deterministic fallback buildPreference always passes ColdOrder as a permutation of the full candidate set, so the cold-order loop hits every eligible candidate. The trailing best/bestIF scan was dead. Replace it with a plain "return """ and document that ColdOrder is guaranteed to cover all candidates, so "" means none were eligible. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * refactor(nodes): fetch model scheduling config once per Route GetModelScheduling was read three times per request - in resolveSelectorCandidates, buildPreference, and nodeMatchesScheduling - three DB round-trips for one row that is immutable for the life of the request, and not a consistent snapshot. Fetch it once near the top of Route and thread the *ModelSchedulingConfig (may be nil) into all three helpers. scheduleNewModel keeps its own fetch since it runs outside the Route snapshot. Behavior is identical for nil sched. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(autoscale): add Pressure.Reset to consume forced-disturb signal Pressure.Count is non-draining (it prunes only by age), so a single burst of forced-disturbs stays within the rolling window for the whole window and keeps Count >= threshold on every reconciler tick. The reconciler will use Reset to clear a model's events after acting on the signal so a fresh scale-up requires fresh forced-disturbs to accumulate, rather than one burst driving the model toward MaxReplicas. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(autoscale): at most one scale-up per reconcile tick, consume pressure Two autoscale bugs: 1. Over-scaling: the pressure scale-up block read Pressure.Count but never consumed it. With a non-draining counter a single forced-disturb burst kept Count >= threshold across the whole window, firing scaleUp on every tick and pushing the model toward MaxReplicas off one transient burst. After a successful pressure-triggered scale-up the reconciler now calls Pressure.Reset to consume the signal. 2. Double scale-up in one tick: the all-replicas-busy block and the pressure block could both fire in the same reconcileModel pass, each calling scaleUp(+1) against the same `current` read once at the top, so a model that was both busy and over threshold scaled +2 and could overshoot MaxReplicas by one. A scaledUp flag now enforces at most one scaleUp(+1) per tick: the pressure block is skipped if the busy block already scaled, and scale-down is skipped in any tick that scaled up. MinReplicas enforcement, UnsatisfiableUntil backoff, and capacity guards are unchanged. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(nodes): replica-removed chokepoint hook for prefix-cache invalidation Add SetReplicaRemovedHook to NodeRegistry and fire it from both RemoveNodeModel and RemoveAllNodeModelReplicas after a successful delete. This is the single chokepoint every replica-removal path funnels through (router eviction, reconciler scale-down, probe reaper, health-monitor node-down reap, RemoteUnloaderAdapter), so the prefix-cache index can be invalidated by construction rather than wiring each call site individually. The hook is stored in an atomic.Pointer so the startup wiring (setter) and the request/reconcile-time fire are race-free; it is nil-safe when unset. GORM Delete reports no error for a no-op delete, so the hook also fires when nothing was removed; the consumer's Invalidate(model, node) is idempotent so this is harmless. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(distributed): invalidate prefix-cache on any replica removal via registry hook Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * refactor(prefixcache): single source of truth for threshold bounds Extract ValidateThresholds into prefixcache/config.go so the per-model override validation (nodes.go endpoint) and Config.Validate share one implementation of the numeric bounds (min_prefix_match in [0,1], balance_abs_threshold >= 0, balance_rel_threshold == 0-or->= 1) instead of hard-coding them in two places. The route_policy allow-list stays explicit (not ParsePolicy, which maps typos to Default). Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(nodes): preserve prefix-cache settings on partial scheduling update A scheduling POST that omitted route_policy/thresholds (e.g. a min_replicas-only update) full-replaced every column and silently reset the model's previously-configured prefix-cache settings to empty/zero. Make the four prefix-cache request fields pointers so omitted is distinguishable from explicit zero, and merge PATCH-style in SetSchedulingEndpoint: a provided pointer wins, an omitted one preserves the existing config value (zero default when none). Non-prefix fields keep their full-replace PUT semantics. Validation now runs on the resolved values via prefixcache.ValidateThresholds. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(prefixcache): make Invalidate a no-op for uncached models and skip empty broadcasts A registry chokepoint fires Sync.Invalidate(model, nodeID) for every replica removal of every model, including round-robin models that never used the prefix cache. Index.Invalidate previously called tree(model), which lazily created and permanently retained an empty radix tree for any model that ever lost a replica, growing the trees map without bound. Sync.Invalidate also published a NATS PrefixCacheInvalidateEvent on every call, amplifying no-op removals across the cluster. Index.Invalidate now looks the tree up read-only via existingTree and returns without allocating when none exists. The Provider interface is unchanged; Sync gates the broadcast through an optional invalidateExisting(bool) capability type-asserted from the wrapped Index, falling back to the prior always-broadcast behavior for other Provider implementations. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * perf(prefixcache): derive Decide candidacy from WeightsFor and skip trivial sort WeightsFor already returns a map keyed by every requested candidate, so the separate candidates set built to validate the hot match was redundant: a node is a candidate iff it is a key in the weights map. Drop the extra map and gate the hot-match check on weights membership. Also skip the sort when there is at most one candidate, since the input order is already the cold order. Behavior is unchanged. Deferred follow-up: skipping the WeightsFor walk entirely when a hot match wins would need lazy cross-file changes and is out of scope here. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(nodes): fire replica-removed hook on bulk node_models deletes; trim LoadedReplicaStats columns Bulk node-scoped node_models deletes (Register re-register cleanup, MarkOffline, MarkDraining, Deregister) removed rows directly without firing the replica-removed hook, so the prefix-cache index kept pointing at nodes whose models were gone. Capture the DISTINCT model names before each bulk delete and fire fireReplicaRemoved once per model after a successful delete, restoring the single-chokepoint invariant for all removal paths. The pre-query is skipped when no hook is set so the no-hook path stays cheap. Also narrow LoadedReplicaStats to SELECT only node_id and in_flight (the only fields the router consumer reads), dropping the JOIN-side available_vram fetch and unused columns while keeping the []ReplicaCandidate return type unchanged. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(reconciler): consume autoscale signals only on a real scale-up scaleUp was fire-and-forget (void) yet its callers unconditionally consumed the pressure signal (Pressure.Reset) and the MinReplicas hysteresis (ClearUnsatisfiable) right after calling it. If scaleUp added nothing (ScheduleAndLoadModel errored, or no node could be loaded) the saturated warm replica got no new replica AND its accumulated forced-disturb history was wiped, forcing the signal to re-accumulate over a full PressureWindow before the next attempt. Make scaleUp return whether at least one replica was actually scheduled, and gate the side effects on it: - pressure block (2b): set scaledUp and call Pressure.Reset only on success; on failure preserve the signal so the next tick retries off the same accumulated pressure. - busy-burst block (2): set scaledUp from the return value so a failed attempt does not suppress the pressure path or scale-down. - MinReplicas block: call ClearUnsatisfiable only on success so a failed attempt does not reset the unsatisfiable counter. All existing invariants (MaxReplicas, capacity gating, UnsatisfiableUntil cooldown, at-most-one-scale-up-per-tick) are preserved. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * refactor(nodes): drop router's redundant prefix-cache Invalidate calls The NodeRegistry removal chokepoint (RemoveNodeModel / RemoveAllNodeModelReplicas) now fires SetReplicaRemovedHook, which invalidates the prefix-cache index. The router was also calling prefixProvider.Invalidate explicitly right after each registry removal on the two stale-replica health-probe fall-throughs in Route and in UnloadModel, so every router-side eviction invalidated twice (double tree-prune + double NATS broadcast). Remove the three redundant explicit Invalidate calls and their empty nil-guards. Each removed call sat immediately after a registry removal that fires the hook, so invalidation is preserved via the chokepoint. Decide/Observe usage is untouched. Re-point the unit test (fake registry fires no hook) to assert the removal chokepoint is exercised on unload instead of the router's direct invalidation. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(prefixcache): broadcast invalidations unconditionally for cross-frontend coherence Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(prefixcache): reject TTL<=0 in Config.Validate (eviction ticker would panic) Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(nodes): make capture+delete atomic in bulk node_models removal paths MarkOffline, MarkDraining, and the Register re-register cleanup ran the nodeModelNames SELECT and the bulk node_models DELETE as two separate statements on r.db with no transaction. A SetNodeModel landing between the two was deleted but its replica-removed hook never fired, leaving the prefix-cache index pointing at a removed replica until TTL or candidacy self-heal. Wrap the capture and the delete in a single db.Transaction in each path (mirroring how Deregister already does it). The captured model names are collected into a slice declared outside the closure; the replica-removed hook fires for each only after the transaction commits, so a rollback never invalidates the index for a removal that did not persist. The set of fired hooks now equals exactly the set of node_models rows actually deleted, with no interleaving gap. The status flip in MarkOffline/MarkDraining (setStatus) is a separate, pre-existing operation and routing already filters non-healthy nodes, so it stays outside the transaction; return contracts are unchanged. Deregister was already correct and is untouched. The cheap-path skip (no hook -> skip the SELECT) is preserved. Adds a spec asserting MarkOffline fires hooks for exactly the rows it deletes and leaves no node_models row behind (consistent snapshot). Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * chore(nodes): debug logging for prefix-cache routing decisions and observations Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(radixtree): match shared prefixes by valuing every node on insert Insert recorded the value (node id) only on the final node of the key chain, leaving every intermediate prefix node valueless. LongestMatch returns the deepest node that hasValue, so two chains that share a leading block but diverge in the tail never matched: only exact-repeat queries hit. That broke the prefix-cache routing core use cases (shared system prompt, multi-turn extension, volatile tail), all of which rely on prefix matching rather than exact-repeat. Set value/hasValue/lastSeen at every node along the chain so each prefix-block node remembers the node id that served that prefix (SGLang/vLLM-style). The deepest match wins, and the last writer owns a shared prefix node (a recency heuristic: the most recent chain through a block is the one most likely still warm). size now counts valued nodes, which is the intended meaning. Updated radixtree tests to the new semantics: deepest-prefix test uses non-overlapping chains, a new test asserts last-writer-owns-shared-node, Evict/Remove/MaxEntries expectations recomputed for per-prefix-node counting, and a shared-prefix LongestMatch red test added. Added a prefixcache Decide test proving a prefix-only query routes to the warm node. No prefixcache .go logic changed. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * test(distributed): lock in prefix-cache routing behavior end to end Add a DB-backed e2e spec that drives SmartRouter against a real NodeRegistry (Postgres testcontainer) and the real prefixcache.Index radix-tree provider, using a fake gRPC backend factory so no real inference runs. Covers the five behaviors validated by hand: 1. Cold miss + observe: an unseen prefix chain cold-places and is recorded. 2. Hot-match affinity: the same chain returns to its warm node X. 3. Shared-prefix match: a divergent chain sharing X's leading prefix still routes to X (the radix-tree regression we fixed). 4. Negative control: an unrelated chain is a cold miss, not a false hot match on X. 5. Failover + invalidation: removing X's replica fires the registry chokepoint hook to invalidate the prefix entry, and the chain fails over to surviving node Y and re-homes there. Replaces the need for manual docker-compose re-runs. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * refactor(prefixcache): make prefix-cache affinity replica-granular Track prefix-cache affinity per loaded replica (a backend process with its own KV cache) instead of per node, so multiple replicas of the same model on one node each keep distinct affinity and a hot prefix routes back to the exact replica that served it. - radixtree: add RemoveFunc(pred) and reimplement Remove on top of it. - prefixcache: introduce ReplicaKey{NodeID, Replica}; Index/Candidate/ PrefixDecision/Select/Provider now key on ReplicaKey. Add InvalidateNode to drop every replica of a node; Invalidate drops one replica. Select returns (ReplicaKey, bool) and gains a deterministic least-in-flight eligible fallback (tiebreak NodeID then Replica). - messaging: carry Replica on PrefixCacheObserveEvent and PrefixCacheInvalidateEvent (Replica < 0 means all replicas of the node). - Sync delegates + broadcasts with replica; InvalidateNode broadcasts Replica=-1; ApplyInvalidate routes negative replica to InvalidateNode. This is part 1 of 2; the registry/router/wiring consumers are updated separately. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(distributed): make prefix-cache routing replica-granular Wire the SmartRouter, NodeRegistry, and distributed startup to the replica-keyed prefixcache API. Affinity is now tracked per replica (each replica is a separate process with its own KV cache), so a prefix served by (node,0) no longer leaks onto the same-node sibling (node,1). - RoutePreference gains PreferredReplica; FindAndLockNodeWithModel locks the EXACT (node_id, replica_index) row, falling through to the default ORDER BY when that replica is not loaded. - SetReplicaRemovedHook now carries replicaIndex; RemoveNodeModel fires the specific replica, RemoveAllNodeModelReplicas and the four bulk node-scoped deletes fire replica<0 (all replicas of the node). - buildPreference builds one Candidate per loaded replica and locks the exact replica the policy chose; observePrefix records the served ReplicaKey at every call site. - distributed.go routes the hook to InvalidateNode (replica<0) or Invalidate(key). - Tests updated to the replica-keyed API plus new coverage: a hot prefix on (node,0) prefers replica 0 over the same-node sibling (router unit + e2e), and FindAndLock locks the exact preferred replica. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(distributed): derive prefix chain from messages for tokenizer-template models Prefix-cache-aware routing built its prompt-prefix chain from the rendered prompt string `s` in ModelInference. For models with TemplateConfig.UseTokenizerTemplate the frontend never renders a prompt - the backend tokenizes the structured messages itself - so `s` is empty, the chain is empty, and routing silently falls back to round-robin. That covers the bulk of modern chat models (qwen3, llama3, ...), so the feature effectively never engaged for them. Fall back to messagesPrefixSource(messages): a deterministic, prefix-stable head-first serialization of the conversation (role + content per turn). Two requests sharing a leading system prompt and early turns share a leading byte prefix, which ExtractChain maps to a shared chain prefix - landing both on the same cache-warm replica. The rendered `s` is still preferred when present (higher fidelity for non-template models). Found via the multi-replica-per-node e2e: zero "prefix-cache routing decision" logs despite per-request Route calls, traced to the empty-chain guard.

Richard Palethorpe	12d1f3a697	security(http): refuse redirects on outbound clients via hardened pkg/httpclient (#10087) ... LocalAI's outbound HTTP clients used Go's default redirect policy, which follows up to 10 redirects. On a cross-host redirect Go forwards custom request headers — including credential headers such as Anthropic's x-api-key — to the redirect target (Go strips Authorization, Cookie and WWW-Authenticate cross-host, but NOT arbitrary custom headers). An attacker able to elicit a redirect from an upstream (a hijacked or spoofed upstream, DNS trickery, or a malicious upstream_url) then harvests the operator's provider API key. This was first reported against the cloud-proxy / MITM PII path (GHSA-3mj3-57v2-4636); the same class affects every other outbound client. Rather than patch each call site, add pkg/httpclient as the one sanctioned constructor for outbound HTTP and route everything through it. pkg/httpclient: - New(...) refuses redirects, TLS 1.2 floor, no body deadline (streaming/SSE safe) - NewWithTimeout(d) simple request/response calls - WithFollowRedirects opt-in following that still strips credential headers on any cross-host hop; different scheme/host/port == different origin, guarding the curl CVE-2022-27774 port-confusion class - WithTransport(rt) keep a custom transport (IP-pin, HTTP/2, a credential-injecting RoundTripper) - HardenedTransport() base transport with the TLS floor + bounded setup - Harden(c) apply the policy to a library-supplied *http.Client - NoRedirect the CheckRedirect policy; wraps ErrRedirectBlocked Lint: a forbidigo rule flags http.DefaultClient and http.Get/Post/ PostForm/Head, pointing at pkg/httpclient (.golangci.yml, .agents/coding-style.md). forbidigo cannot match the &http.Client{} composite literal without also flagging legitimate *http.Client type references, so that form is enforced by review. Migrates every non-test outbound call site across core/, pkg/, cmd/, and the Go backend (backend/go/cloud-proxy). Credential-bearing and internal-RPC clients refuse redirects; download / CDN / registry clients use WithFollowRedirects so they keep working while stripping secrets cross-host. The only credential-bearing client that follows redirects is the gated-download path (pkg/downloader/uri.go), which strips the token on the cross-host hop to the CDN. Hardening this closes, in passing: - MCP remote-server bearer token leaking via a redirect (the RoundTripper re-injected Authorization on every hop) - agent multimedia/webhook clients leaking user-supplied auth headers - cors_proxy following redirects, bypassing its SSRF IP-pin - downloader's authorized read path leaking the token cross-host Fixes: GHSA-3mj3-57v2-4636 (cloud-proxy leaks operator provider API key (x-api-key) to attacker host on cross-host redirect) Reported-by: tonghuaroot Assisted-by: Claude:claude-opus-4-8 [Claude Code] Signed-off-by: Richard Palethorpe <io@richiejp.com>	2026-05-30 12:04:10 +02:00
Richard Palethorpe	fbcd886a47	fix(application): stop backend processes synchronously on shutdown (#10058) ... application.New wires a fire-and-forget goroutine that runs StopAllGRPC + distributed.Shutdown when the app context is cancelled. Callers (tests, CLI signal handler) cancel the context and then exit immediately, so the test binary / process can terminate before that goroutine kills the spawned backend children. go-processmanager sets no Pdeathsig, so the orphans are reparented to init and survive — leaving dozens of stray mock-backend processes after an e2e run. Add Application.Shutdown(), which runs the same cleanup synchronously on the caller's stack and is idempotent via sync.Once. The context-cancel goroutine, the CLI signal handler, and the test suites all call it, so cleanup is deterministic and the duplicated teardown logic collapses to one place. The async goroutine remains as a safety net for callers that forget; sync.Once dedupes the double call. Wire e2e_suite_test and the two mock-backend Contexts in app_test to call Shutdown in their AfterSuite/AfterEach.

LocalAI [bot]	06e777b75e	feat(distributed): gated X-LocalAI-Node response header (middleware + wrapper) (#9976) ... * feat(distributed): add per-request node ID context holder Introduce pkg/distributedhdr, a leaf package carrying a per-request *atomic.Value holder for the picked worker node ID from the SmartRouter (core/services/nodes) up to the HTTP response writer wrapper (core/http/middleware). Avoids the import cycle that a shared key in either consumer would create. Exposes NewHolder, WithHolder, Holder, Stamp, Load, Inherit. The holder is atomic.Value so cross-goroutine publish from the router to the response writer wrapper is race-clean. Assisted-by: Claude:claude-opus-4-7[1m] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(distributed): add ExposeNodeHeader middleware + response writer wrapper New ApplicationConfig.ExposeNodeHeader bool + --expose-node-header CLI flag / LOCALAI_EXPOSE_NODE_HEADER env var (default off; the node ID reveals internal topology and is opt-in). The middleware creates a per-request *atomic.Value holder, attaches it to c.Request().Context() via distributedhdr.WithHolder, and wraps c.Response().Writer with a custom http.ResponseWriter that sets the X-LocalAI-Node header on first Write / WriteHeader / Flush by reading the holder. Implements http.Flusher, http.Hijacker, Unwrap so it composes cleanly with Echo and http.NewResponseController. request.go propagates the holder onto derived contexts via distributedhdr.Inherit so the holder survives the correlation-ID context replacement. Unit + race-clean concurrency + integration specs. Assisted-by: Claude:claude-opus-4-7[1m] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(distributed): stamp node ID in router and wire middleware to inference routes ModelRouterAdapter.Route stamps the picked node ID into the per-request holder via distributedhdr.Stamp(ctx, result.Node.ID) right after replica selection. Wire ExposeNodeHeader middleware to: - OpenAI chat/completion/embeddings + audio transcriptions/speech + image generations/inpainting - Anthropic /v1/messages - Ollama /api/chat, /api/generate, /api/embed, /api/embeddings - Jina /v1/rerank - LocalAI /v1/vad The middleware's wrapper reads the holder on first byte and sets the X-LocalAI-Node response header before delegating to the underlying writer. Per-request scope means no race under concurrent multi-replica routing. Assisted-by: Claude:claude-opus-4-7[1m] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(distributed): thread request context through backend Load + cover ctx propagation Five non-OpenAI backend helpers were silently using app.Context instead of the request context for the gRPC backend call: transcription, TTS, image generation, rerank, VAD. Effect: distributedhdr.Stamp in the router callback was a silent no-op for these paths, AND client cancellation didn't propagate to in-flight inference. Thread c.Request().Context() (or the equivalent input.Context after the request middleware has installed the correlation-ID derived context) through each helper and into ModelOptions via model.WithContext(ctx). ImageGeneration's signature gains a leading ctx parameter; in-tree callers (openai image, openai inpainting, openai inpainting_test) are updated to match. ModelEmbedding gains a leading ctx parameter for the same reason; the openai and ollama embedding handlers pass the request context through. chat_stream_workers.go defers the initial role=assistant chunk emission until the first token callback so the wrapper's lazy X-LocalAI-Node lookup against the loader runs AFTER ml.Load has stamped the per-modelID node ID; semantically identical for clients (role still arrives before any text).

LocalAI [bot]	a0f3e26245	fix(distributed): make admin backend installs resilient and observable (#9958) ... * feat(distributed): add configurable NATS backend install/upgrade timeouts Adds BackendInstallTimeout and BackendUpgradeTimeout to DistributedConfig with 15m defaults, following the existing MCPToolTimeout / WorkerWaitTimeout pattern.

Install now defaults to 15m (was 3m); cold OCI image pulls on Jetson Wi-Fi routinely blew past the old ceiling.

Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(distributed): introduce galleryop.ErrWorkerStillInstalling sentinel When the NATS request-reply for backend.install (or .upgrade) times out the worker is almost always still pulling the OCI image.

Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(distributed): treat NATS install timeout as in-progress, not failure When a worker times out replying to backend.install but the install is still running on the worker, enqueueAndDrainBackendOp now reports a running_on_worker status and pushes NextRetryAt out by the install timeout so the reconciler does not immediately re-fire another install while the worker is still pulling the image. The pending_backend_ops row stays in place for the next reconciler pass to confirm via backend.list. InstallBackend wraps the result in galleryop.ErrWorkerStillInstalling so callers can branch (galleryop renders yellow in-progress instead of red error). UpgradeBackend uses the same wrap. Adds RemoteUnloaderAdapter.InstallTimeout() so the manager can push NextRetryAt by the configured timeout without reaching into a private field, and NodeRegistry.RecordPendingBackendOpInFlight as the soft cousin of RecordPendingBackendOpFailure. Also includes incidental gofmt-driven struct-field alignment in registry.go on lines unrelated to the change (touched files are re-formatted to canonical form per project policy). Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(distributed): don't increment Attempts on in-flight install timeout An in-flight timeout (worker still pulling the OCI image) is not a failed attempt, it's a delayed one. Incrementing Attempts let genuinely-progressing slow installs (e.g. 30 GB CUDA images on Wi-Fi) trip the reconciler's maxPendingBackendOpAttempts cap and dead-letter the queue row while the worker was still legitimately working. RecordPendingBackendOpInFlight now only updates LastError and NextRetryAt. Also documents "running_on_worker" in the NodeOpStatus.Status enum comment so Task 6 implementers see the full surface. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(galleryop): surface ErrWorkerStillInstalling as non-error OpStatus When the distributed backend manager returns an error that wraps ErrWorkerStillInstalling, backendHandler now completes the op with a "still installing in background" message rather than marking it as a red failure.

Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * test(distributed): end-to-end install-timeout-then-reconcile Wires Task 1-6 end-to-end so any seam mismatch surfaces in CI rather than during a real cluster install.

Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * docs(distributed): document LOCALAI_NATS_BACKEND_INSTALL_TIMEOUT / _UPGRADE_TIMEOUT Add the two new operator-tunable env vars to the Frontend Configuration table in the distributed-mode docs.

Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(distributed): clear pending install rows when backend.list confirms DistributedBackendManager.ListBackends now proactively clears pending_backend_ops install rows whose (nodeID, backend) is reported installed by backend.list. Operator UI updates immediately instead of waiting up to installTimeout (default 15m) for the next reconciler tick after NextRetryAt. Only install rows are cleared; upgrade and delete intents are not satisfied by presence in backend.list and continue to drain through their normal reconciler paths. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(messaging): add BackendInstallProgressEvent wire type and subject New NATS subject nodes.<nodeID>.backend.install.<opID>.progress lets the worker publish transient progress events (file, current/total bytes, percentage, phase) while a long-running install pulls its OCI image. BackendInstallRequest gains an optional OpID field so the worker knows which subject to publish on. Transient pub/sub (not JetStream): the install reply remains ground truth for success/failure; dropped progress events are tolerable. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * style(messaging): drop em-dash from BackendInstallProgress test comment Per project convention (no em-dashes anywhere). Comment substance is unchanged. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(distributed): worker publishes debounced install progress over NATS When BackendInstallRequest.OpID is set, the worker's backend.install handler wires a debounced publisher (250ms window) into the gallery download callback. Each tick becomes a BackendInstallProgressEvent on nodes.<nodeID>.backend.install.<opID>.progress; the publisher always emits a final event on Flush so the UI sees the terminal percentage. Old masters that do not set OpID continue to run silent installs: no behavior change for them. Lock ordering: the publisher releases its mutex before calling messaging.Publish so a slow network never stalls the install loop. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(distributed): RemoteUnloaderAdapter subscribes to install progress InstallBackend gains opID + onProgress parameters. When both are set, the adapter subscribes to nodes.<nodeID>.backend.install.<opID>.progress BEFORE publishing the install request, decodes each message into the caller's onProgress callback in a goroutine (so a slow callback never stalls the NATS reader thread), and unsubscribes after RequestJSON returns. When onProgress is nil OR opID is empty (the reconciler retry path), subscription is skipped entirely - silent installs cost nothing extra. Subscribe failure is logged at Warn and the install proceeds without progress streaming; the NATS round-trip still owns terminal status. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(distributed): forward backend install progress into galleryop OpStatus DistributedBackendManager.InstallBackend now passes the gallery op ID and a progress bridge into the adapter call. Each BackendInstallProgressEvent from the worker becomes a galleryop.ProgressCallback tick - which the existing backendHandler already turns into OpStatus.UpdateStatus, so the admin UI/SSE polling sees per-byte progress for distributed installs without any UI-side change. UpgradeBackend is intentionally left silent for now: its wire request (BackendUpgradeRequest) does not carry OpID, and rolling-update fallback is the rarer path. Will be picked up in a follow-up if the worker upgrade path also gets a progress channel. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * test(distributed): InstallBackend tolerates silent (pre-Phase-2) workers A worker on pre-Phase-2 code never publishes progress events. The new master subscribes optimistically; this spec pins that a silent worker still produces a green install with no progressCb ticks. The install reply is the source of truth for terminal state; the progress stream is a best-effort UX enrichment. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * docs(distributed): document install progress streaming Note the new nodes.<nodeID>.backend.install.<opID>.progress subject and the silent-worker compatibility behavior so operators know to expect real-time progress and what happens on a mixed-version cluster. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * docs(distributed): note progress-event ordering trade-off in InstallBackend Document near the goroutine dispatch why ordering at the consumer is best-effort, why it rarely matters in practice (worker debounce >> goroutine jitter), and what a future hardening pass would look like (Seq field + stale-by-seq drop). Stops the next reader from accidentally "fixing" the goroutine pool away. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(galleryop): add NodeProgress + OpStatus.Nodes for per-node breakdown Adds the data model the UI needs to render an expandable per-node breakdown of a fanned-out backend install. NodeProgress carries node identity (ID + name), per-node status (queued / running_on_worker / success / error / downloading), the current file + bytes + percentage from the Phase 2 progress stream, and any per-node error. OpStatus.Nodes is the slice the /api/operations handler will surface in a follow-up. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(galleryop): UpdateNodeProgress merges per-node ticks by NodeID GalleryService.UpdateNodeProgress(opID, nodeID, np) merges a NodeProgress into OpStatus.Nodes (keyed by NodeID, no duplicates) and mirrors the latest tick into the aggregate Progress / FileName / DownloadedFileSize / TotalFileSize fields so the legacy single-bar OperationsBar view keeps working unchanged alongside the new per-node breakdown. Concurrent-safe via the existing g.Mutex. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(distributed): write per-node OpStatus entries during install fan-out DistributedBackendManager now accepts a nodeProgressSink and feeds it two streams: 1. enqueueAndDrainBackendOp emits a per-node terminal entry on each status it appends to BackendOpResult (queued, success, error, running_on_worker). The opID is threaded through the function so the sink gets the right gallery op identity. 2. The install apply closure fans each BackendInstallProgressEvent into the sink as a downloading entry, alongside the legacy progressCb path so the aggregate single-bar view stays correct. Production wiring passes the GalleryService (which implements UpdateNodeProgress via Task 2) as the sink. Single-node tests pass nil. DeleteBackend and UpgradeBackend pass an empty opID so the sink path no-ops for ops that aren't gallery-tracked the same way as Install. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(operations): expose per-node breakdown on /api/operations When an operation's OpStatus has Nodes entries (populated by the Phase 4 progress sink wiring), surface them as a "nodes" array on the /api/operations response, sorted by node_name for stable rendering. Backward compatible: legacy clients ignore the field; ops without any node entries (single-node mode, model installs) omit the array entirely thanks to the empty-slice guard. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(ui): per-node breakdown in OperationsBar When an install op fans out to more than one worker, the operations bar now shows a "N nodes" chevron that expands into a per-node list. Each row carries the node's status (color-coded pill), the current file being downloaded, byte counts, percentage, and a thin per-node progress bar. Yellow "Worker busy" pill marks running_on_worker status with a tooltip explaining the NATS round-trip timed out but the worker is still installing in the background. Backward compatible: ops without a nodes field (legacy or single-node mode) render as before. State for expand/collapse is local to the component, keyed by jobID/id - reload starts collapsed. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * docs(distributed): document per-node breakdown in the operations bar Adds a short subsection covering the expandable "N nodes" chevron in the OperationsBar admin UI, the meaning of each status pill, and how it relates to the /api/operations nodes array. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(galleryop): UpdateStatus preserves Nodes when caller sends none Real-world bug surfaced by the Phase 4 multi-worker smoke test: the nodes[] array in /api/operations flickered between a single node at a time on a 2-worker install. Root cause: the Phase 2 progress bridge also calls the legacy progressCb -> UpdateStatus(&OpStatus{...}) on every tick. UpdateStatus then overwrote the entire status pointer, wiping the Nodes slice that UpdateNodeProgress had just merged in. Fix: in UpdateStatus, if the incoming op has an empty Nodes slice, carry forward the previous status's Nodes before storing. Callers that explicitly populate Nodes still win (their slice replaces the prior one, no merge across the two code paths). Two regression specs added pinning both directions of the contract. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * docs(distributed): strip implementation details from user-facing docs Trim the new install/upgrade timeout rows and the install-progress sections to focus on what the operator sees and tunes. Drops: - the NATS subject names and pub/sub mechanics - "round-trip" / reconciler / backend.list jargon - /api/operations polling cadence - "pre-2026-05-22" version references Reframes the breakdown text around the admin UI (Operations Bar, chevron, status pills, "Worker busy" tooltip). Implementation context lives in the agent notes and code comments. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * refactor(config): move DistributedConfig.Validate flag names to constants The negative-duration check map was a wall of literal kebab-case strings that had to stay in sync with the kong-derived CLI flag names manually. Move them to a Flag* const block alongside the existing Default* block so a rename of either the Go field or the CLI naming convention forces a compile error rather than silent drift. Sole consumer today is Validate; the constants are exported so future operator-facing surfaces (e.g. error messages on other validation paths) can reference them by name instead of repeating the literals. Tests pin both the literal values (so a future "let's just rename this" doesn't accidentally regress the CLI flag) and the negative- duration error message for the new BackendInstall / BackendUpgrade fields. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * refactor(distributed): extract NodeStatus and Phase enums to constants Sweep for the same literal-string-as-identifier pattern called out on the Validate flag names: the per-node install status enum ("queued" | "downloading" | "running_on_worker" | "success" | "error") appeared as raw literals across managers_distributed.go (10+ sites, including 3 separate `n.Status == "running_on_worker"` checks), operation.go, and the test suite. Same shape for the Phase enum ("resolving" | "downloading" | "extracting" | "starting") in the worker-side progress publisher. Promote both to exported const blocks: - galleryop.NodeStatus{Queued,Downloading,RunningOnWorker,Success,Error} shared between galleryop.NodeProgress.Status (the wire field) and nodes.NodeOpStatus.Status (the in-process per-node summary) - messaging.Phase{Resolving,Downloading,Extracting,Starting} shared between the worker publisher and any future consumer that needs to switch on phase Tests pin both the literal values (so a future "let's just rename" doesn't silently change the JSON wire) and use the constants in setup (so the producer side stays drift-protected). Wire-format assertions on the /api/operations JSON output keep their literals deliberately, so the constant value can never silently diverge from what the UI receives. Out of scope for this PR (separate cleanup): the finetune and quantization job-status enums have the same anti-pattern with 14+ literal sites each, but predate this PR's work.

LocalAI [bot]	61bf34ea2f	fix(traces): cap captured body size to keep admin Traces UI responsive (#9946) ... The trace middleware buffered the full request and response bodies for every JSON exchange. With a chatty agent-pool RAG workload, /embeddings responses (large vector arrays) accumulated to tens of MB in the in-memory buffer; the admin Traces page would then download and parse 40+ MB on every load and on every 5s auto-refresh, locking the UI in a loading state. Add LOCALAI_TRACING_MAX_BODY_BYTES (default 64 KiB) that caps each captured body. The full payload still flows through to the real client; only the trace copy is bounded. Exchanges record body_truncated and original body_bytes so the dashboard can show that truncation happened. The cap is configurable via env, CLI, and runtime_settings.json. Also unblock recovery: the Traces page now keeps the Clear button enabled while loading, since "buffer too large to render" is exactly when the user needs to clear it.

Richard Palethorpe	5d0b549049	feat(gallery): verify backend OCI images with keyless cosign (#9823) ... * feat(gallery): verify backend OCI images with keyless cosign Close a trust gap where a registry compromise or MITM could silently replace a backend image: the gallery YAML tells LocalAI which image to pull, but until now nothing verified the bytes came from our CI. Consumer (pkg/oci/cosignverify): - New package using sigstore-go to verify keyless-cosign signatures. - OCI 1.1 referrers API + new bundle format (no legacy :tag.sig). - Policy fields: Issuer / IssuerRegex / Identity / IdentityRegex / NotBefore. NotBefore is the revocation lever — keyless Fulcio certs are ephemeral so revocation is policy-side; advancing not_before in the gallery YAML invalidates every signature predating the cutoff. - TUF trusted root cached process-wide so N backends from one gallery do 1 fetch, not N. Plumbing: - pkg/downloader: ImageVerifier interface + WithImageVerifier option threaded through DownloadFileWithContext. Verification runs between oci.GetImage and oci.ExtractOCIImage, with digest pinning via pinnedImageRef to close the TOCTOU window. Skips the verifier's HEAD when the ref is already digest-pinned. - core/config: Gallery.Verification YAML block. - core/gallery: backendDownloadOptions builds the verifier from the policy; applied on initial URI, mirrors, and tag fallbacks. - core/gallery/upgrade: the upgrade path now routes through the same options builder. A regression Ginkgo spec pins this contract — without it, UpgradeBackend silently bypassed verification. - core/cli: --require-backend-integrity (LOCALAI_REQUIRE_BACKEND_INTEGRITY) escalates missing policy / empty SHA256 from warn to hard-fail. Producer (.github/workflows/backend_merge.yml): - id-token: write at job scope (PR-fork-safe via existing event gate). - sigstore/cosign-installer@v3 pinned to v2.4.1. - After each docker buildx imagetools create, resolve the manifest list digest and run cosign sign --recursive --new-bundle-format --registry-referrers-mode=oci-1-1 against repo@digest. --recursive signs the index and every per-arch entry, matching how the consumer resolves a tag to a platform-specific manifest before verifying. Rollout: backend/index.yaml has no `verification:` block yet, so this PR is backward-compatible — installs proceed with a warning until the gallery is populated. Strict mode is opt-in.

This leaked process state into the gallery package and made the flag impossible to override per-call or test without touching the env. Add RequireBackendIntegrity to ApplicationConfig (with a matching WithRequireBackendIntegrity AppOption) and thread the bool through every install/upgrade path: InstallBackend, InstallBackendFromGallery, UpgradeBackend, InstallModelFromGallery, InstallExternalBackend, ApplyGalleryFromString/File, startup.InstallModels. Worker subcommands gain the same env-bound flag on WorkerFlags so distributed-worker installs honor it consistently with the worker daemon path. Add a forbidigo lint rule against os.Getenv / os.LookupEnv / os.Environ to keep the env-leak pattern from creeping back. Existing offenders (p2p, config loaders, etc.) are baseline-grandfathered by the existing new-from-merge-base: origin/master setting; targeted path exclusions cover the legitimate cases — kong CLI entry points, backend subprocesses, system capability probes, gRPC AUTH_TOKEN inheritance, test gating env vars.

Richard Palethorpe	670259ce43	chore: Security hardening (#9719) ... * fix(http): close 0.0.0.0/[::] SSRF bypass in /api/cors-proxy The CORS proxy carried its own private-network blocklist (RFC 1918 + a handful of IPv6 ranges) instead of using the same classification as pkg/utils/urlfetch.go. The hand-rolled list missed 0.0.0.0/8 and ::/128, both of which Linux routes to localhost — so any user with FeatureMCP (default-on for new users) could reach LocalAI's own listener and any other service bound to 0.0.0.0:port via: GET /api/cors-proxy?url=http://0.0.0.0:8080/... GET /api/cors-proxy?url=http://[::]:8080/... Replace the custom check with utils.IsPublicIP (Go stdlib IsLoopback / IsLinkLocalUnicast / IsPrivate / IsUnspecified, plus IPv4-mapped IPv6 unmasking) and add an upfront hostname rejection for localhost, *.local, and the cloud metadata aliases so split-horizon DNS can't paper over the IP check. The IP-pinning DialContext is unchanged: the validated IP from the single resolution is reused for the connection, so DNS rebinding still cannot swap a public answer for a private one between validate and dial. Regression tests cover 0.0.0.0, 0.0.0.0:PORT, [::], ::ffff:127.0.0.1, ::ffff:10.0.0.1, file://, gopher://, ftp://, localhost, 127.0.0.1, 10.0.0.1, 169.254.169.254, metadata.google.internal.

Subsequent code that operated on filePath (a backend launcher, a YAML loader, a re-download that finds the file already present and skips) would consume the attacker-supplied bytes. Reorder: verify the streamed hash first, remove the .partial on mismatch, then rename. The streamed hash is computed during io.Copy so no second read is needed. While here, raise the empty-SHA case from a Debug log to a Warn so "this download had no integrity check" is visible at the default log level. Backend installs currently pass through with no digest; the warning makes that footprint observable without changing behaviour. Regression test asserts os.IsNotExist on the destination after a deliberate SHA mismatch.

With LOCALAI_ADMIN_EMAIL set, an attacker who could register on the configured OIDC IdP under that email (some IdPs accept self-supplied unverified emails) inherited admin role: - first login: AssignRole(tx, email, adminEmail) → RoleAdmin - re-login: MaybePromote(db, user, adminEmail) → flip to RoleAdmin Add EmailVerified to oauthUserInfo, parse email_verified from the OIDC claims (default false on absence so an IdP that omits the claim cannot short-circuit the gate), and substitute "" for the role-decision email when verified=false via emailForRoleDecision. The user record still stores the unverified email for display. GitHub's path defaults EmailVerified=true: GitHub only returns a public profile email after verification, and fetchGitHubPrimaryEmail explicitly filters to Verified=true. Regression tests cover both the helper contract and integration with AssignRole, including the bootstrap "first user" branch that would otherwise mask the gate.

That is fine for a developer laptop, a home LAN, or a Tailnet — the network itself is the trust boundary. It is not fine on a public IP, where every model install, settings change, and admin endpoint becomes reachable from the internet. Refuse to start in that exact configuration. Loopback, RFC 1918, RFC 4193 ULA, link-local, and RFC 6598 CGNAT (Tailscale's default range) all count as trusted; wildcard binds (`:port`, `0.0.0.0`, `[::]`) are accepted only when every host interface is in one of those ranges. Hostnames are resolved and treated as trusted only when every answer is. A new --allow-insecure-public-bind / LOCALAI_ALLOW_INSECURE_PUBLIC_BIND flag opts out for deployments that gate access externally (a reverse proxy enforcing auth, a mesh ACL, etc.). The error message lists this plus the three constructive alternatives (bind a private interface, enable --auth, set --api-keys). The interface enumeration goes through a package-level interfaceAddrsFn var so tests can simulate cloud-VM, home-LAN, Tailscale-only, and enumeration-failure topologies without poking at the real network stack.

The chat route is FeatureChat-gated (default-on), and the assistant's in-process MCP server can install/delete models and edit configs — the wrong handler change would silently turn the LLM into a confused deputy. Extract the gate into requireAssistantAccess(c, authEnabled) and pin its behaviour: auth disabled is a no-op, unauthenticated is 403, RoleUser is 403, RoleAdmin and the synthetic legacy-key admin are admitted.

A new endpoint shipped under a brand-new prefix — or a new path that simply isn't on the prefix allowlist — would be reachable anonymously. Walk every route registered by API() with auth enabled and a fresh in-memory database (no users, no keys), and assert each API-prefixed route returns 401 / 404 / 405 to an anonymous request. Public surfaces (/api/auth/*, /api/branding, /api/node/* token-authenticated routes, /healthz, branding asset server, generated-content server, static assets) are explicit allowlist entries with comments justifying them.

Lock in the contract: - effectiveUserID ignores ?user_id= for unauthenticated and RoleUser - effectiveUserID honours it for RoleAdmin and ProviderAgentWorker - wantsAllUsers requires admin AND the literal "true" string - canImpersonateUser is admin OR agent-worker, never plain RoleUser No production change — this commit only adds tests.

Body redaction is left to a follow-up — the prompts are usually the operator's own and JSON-walking is invasive.

The CSP keeps script-src permissive because the Vite bundle relies on inline + eval'd scripts; tightening that requires moving to a nonce-based policy. - The <base href> injection in the SPA shell escaped attacker-controllable Host / X-Forwarded-Host headers — a single quote in the host header broke out of the attribute. Pass through SecureBaseHref (html.EscapeString). - Three React sinks rendering untrusted content via dangerouslySetInnerHTML switch to text-node rendering with whiteSpace: pre-wrap: user message bodies in Chat.jsx and AgentChat.jsx, and the agent activity log in AgentChat.jsx. The hand-rolled escape on the agent user-message variant is replaced by the same plain-text path. - New safeHref util collapses non-allowlisted URI schemes (most importantly javascript:) to '#'. Applied to gallery `<a href={url}>` links in Models / Backends / Manage and to canvas artifact links — these come from gallery JSON or assistant tool calls and must be treated as untrusted. - The branding asset server attaches a sandbox CSP plus same-origin CORP to .svg responses. The React UI loads logos via <img>, but the same URL is also reachable via direct navigation; this prevents script execution if a hostile SVG slipped past upload validation.

ReadTimeout and WriteTimeout stay at 0 because request bodies can be multi-GB model uploads and SSE / chat completions stream for many minutes; operators who need tighter per-request bounds should terminate slow clients at a reverse proxy.

An operator who flipped the strict-CORS feature flag without populating the list got the opposite of what they asked for.

LocalAI has no second factor yet, so the bar needs to sit higher. Add ValidatePasswordStrength using github.com/timbutler/zxcvbn (an actively-maintained fork of the trustelem port; v1.0.4, April 2024): - min 12 chars, max 72 (bcrypt's truncation point) - reject NUL bytes (some bcrypt callers truncate at the first NUL) - require zxcvbn score >= 3 ("safely unguessable, ~10^8 guesses to break"); the hint list ["localai", "local-ai", "admin"] penalises passwords built from the app's own branding zxcvbn produces false positives sometimes (a strong-looking password that happens to match a dictionary word) and operators occasionally need to set a known-weak password (kiosk demos, CI rigs). Add an acknowledgement path: PasswordPolicy{AllowWeak: true} skips the entropy check while still enforcing the hard rules. The structured PasswordErrorResponse marks weak-password rejections as Overridable so the UI can surface a "use this anyway" checkbox.

Loosening the CSP would defeat its purpose; the right fix is to stop reaching out to a third-party CDN for fonts on every page load. Add @fontsource-variable/geist and @fontsource-variable/geist-mono as npm deps and import them once at boot. Drop the <link rel="preconnect"> and external stylesheet from index.html.

Treating length-12 as a hard rule was inconsistent with the entropy check (already overridable) and friction for use cases where the account is just a name on a session, not a security boundary (single-user kiosk, CI rig, lab demo). Restructure ValidatePasswordStrength: - Hard rules (always enforced): non-empty, <= MaxPasswordLength, no NUL byte - Policy rules (skipped when AllowWeak=true): length >= 12, zxcvbn score >= 3 PasswordError now marks password_too_short as Overridable too.

Assisted-by: Claude:claude-opus-4-7 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(distributed/worker): run backend.install handler in a goroutine NATS subscriptions deliver messages serially on a single per-subscription goroutine. With a synchronous install handler, a multi-minute gallery download would head-of-line-block every other install request to the same worker — manifesting upstream as a 5-minute "nats: timeout" on unrelated routine model loads. The body now runs in its own goroutine, with a per-backend mutex (lockBackend) protecting the gallery directory from concurrent operations on the same backend. Different backend names install in parallel. Backward-compat: req.Force=true is still honored here, so an older master that hasn't been updated to send on backend.upgrade keeps working.

Same per-backend mutex guards both — concurrent install + upgrade for the same backend serialize at the gallery directory; different backends are independent. upgradeBackend stops every live process for the backend, force-installs from gallery, and re-registers. It does not start a new process — the next backend.install will spawn one with the freshly-pulled binary. Assisted-by: Claude:claude-opus-4-7 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * feat(distributed): add UpgradeBackend on NodeCommandSender; drop Force from InstallBackend Master now sends to backend.upgrade for force-reinstall, with a nats.ErrNoResponders fallback to the legacy backend.install Force=true path so a rolling update with a new master + an old worker still converges. The Force parameter leaves the public Go API surface entirely — only the internal fallback sets it on the wire. InstallBackend timeout drops 5min -> 3min (most replies are sub-second since the worker short-circuits on already-running or already-installed). UpgradeBackend timeout is 15min, sized for real-world Jetson-on-WiFi gallery pulls. Updates the admin install HTTP endpoint (core/http/endpoints/localai/nodes.go) to the new signature too. router_test.go's fakeUnloader does not yet implement the new interface shape; Task 3.2 will catch it up before the next package-level test run.

Updates them to script SubjectNodeBackendUpgrade with BackendUpgradeReply. Adds two new specs for the rolling-update fallback: - ErrNoResponders on backend.upgrade triggers a backend.install Force=true retry on the same node. - Non-NoResponders errors propagate to the caller unchanged. scriptedMessagingClient gains scriptNoResponders (real nats sentinel) and scriptReplyMatching (predicate-matched canned reply, used to assert that the fallback path actually sets Force=true on the install retry).

SmartRouter now wraps the NATS round-trip in a singleflight.Group keyed by (nodeID, backend, modelID, replica): N concurrent identical loads share one round-trip and one reply. Distinct (modelID, replica) keys still fire independent calls, so multi-replica scaling and multi-model fan-out are unaffected. fakeUnloader gains a sync.Mutex around its recording slices to keep concurrent test goroutines race-clean.

The CLI package was carrying backendSupervisor, NATS lifecycle handlers, gallery install/upgrade orchestration, S3 file staging, and registration helpers — all distributed-worker business logic that doesn't belong in the cobra surface. Move it to a new core/services/worker package, mirroring the existing core/services/{nodes,messaging,galleryop} pattern. core/cli/worker.go shrinks to ~19 lines: a kong-tagged shim that embeds worker.Config and delegates Run. No behavior change. All symbols stay unexported except Config and Run. The three worker-specific tests (addr/replica/concurrency) move with the code via git mv so history follows them. Files split as: worker.go - Run entry point config.go - Config struct (kong tags retained, kong not imported) supervisor.go - backendProcess, backendSupervisor, process lifecycle install.go - installBackend, upgradeBackend, findBackend, lockBackend lifecycle.go - subscribeLifecycleEvents (verbatim, decomposition is a follow-up commit) file_staging.go - subscribeFileStaging, isPathAllowed registration.go - advertiseAddr, registrationBody, heartbeatBody, etc. reply.go - replyJSON process_helpers.go - readLastLinesFromFile Assisted-by: Claude:claude-opus-4-7 Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * refactor(distributed/worker): decompose subscribeLifecycleEvents into per-event handlers The 226-line subscribeLifecycleEvents method packed eight NATS subscriptions inline. Each grew context-shaped doc comments mixed with subscription plumbing, making it hard to read any one handler without scrolling past the others. Extract each handler into its own method on *backendSupervisor; the subscriber becomes a thin 8-line dispatcher. No behavior change: each method body is byte-equivalent to its corresponding inline goroutine + handler. Doc comments that were attached to the inline SubscribeReply calls migrate to the new method godocs. Adding the next NATS subject is now a 2-line patch to the dispatcher plus one new method, instead of grafting onto a monolith.

The previous commit used `defer close(done)` and called the watcher "joined synchronously" — but close() only signals, it does not block until the goroutine exits. That left a window where a late CppSetAbort(1) from a cancelled call could land on the next call, after its C-side g_abort reset but before whisper_full() began polling the abort callback, corrupting the second transcription.

Convert the cancellation test to a Describe/It block with Skip(...) for env gating and Expect/HaveOccurred for assertions.

LocalAI [bot]	447c186089	fix(distributed): make backend upgrade actually re-install on workers (#9708) ... * fix(distributed): make backend upgrade actually re-install on workers UpgradeBackend dispatched a vanilla backend.install NATS event to every node hosting the backend. The worker's installBackend short-circuits on "already running for this (model, replica) slot" and returns the existing address — so the gallery install path was skipped, no artifact was re-downloaded, no metadata was written. The frontend's drift detection then re-flagged the same backends every cycle (installedDigest stays empty → mismatch → "Backend upgrade available (new build)") while "Backend upgraded successfully" landed in the logs at the same time. The user-visible symptom: clicking "Upgrade All" silently does nothing and the same N backends sit on the upgrade list forever. Two coupled fixes, one PR: 1. Force flag on backend.install. Add `Force bool` to BackendInstallRequest and thread it through NodeCommandSender -> RemoteUnloaderAdapter. UpgradeBackend (and the reconciler's pending-op drain when retrying an upgrade) sets force=true; routine load events and admin install endpoints keep force=false. On the worker, force=true stops every live process that uses this backend (resolveProcessKeys for peer replicas, plus the exact request processKey), skips the findBackend short-circuit, and passes force=true into gallery.InstallBackendFromGallery so the on-disk artifact is overwritten. After the gallery install completes, startBackend brings up a fresh process at the same processKey on a new port. 2. Liveness check on the fast path. installBackend's "already running" branch read getAddr without verifying the process was alive, so a gRPC backend that died without the supervisor noticing left a stale (key, addr) entry. The reconciler then dialed that address, got ECONNREFUSED, marked the replica failed, retried install — and the supervisor said "already running addr=…" again. Loop forever, exactly what we observed on a node whose llama-cpp process had died but whose supervisor record persisted. Verify s.isRunning(processKey) before trusting getAddr; if the entry is stale, stopBackendExact cleans up and we fall through to a real install. Backwards-compatible: the new Force field is omitempty, older workers ignore it (their default behavior matches force=false). The signature change on NodeCommandSender.InstallBackend is internal-only. Verified: unit tests in core/services/nodes pass (108s suite). The pre-existing core/backend build break (proto regen pending for word-level timestamps) blocks core/cli and core/http/endpoints/localai package tests but is unrelated to this change.

Richard Palethorpe	8e43842175	feat(vllm, distributed): tensor parallel distributed workers (#9612) ... * feat(vllm): build vllm from source for Intel XPU Upstream publishes no XPU wheels for vllm. The Intel profile was silently picking up a non-XPU wheel that imported but errored at engine init, and several runtime deps (pillow, charset-normalizer, chardet) were missing on Intel -- backend.py crashed at import time before the gRPC server came up. Switch the Intel profile to upstream's documented from-source procedure (docs/getting_started/installation/gpu.xpu.inc.md in vllm-project/vllm): - Bump portable Python to 3.12 -- vllm-xpu-kernels ships only a cp312 wheel. - Source /opt/intel/oneapi/setvars.sh so vllm's CMake build sees the dpcpp/sycl compiler from the oneapi-basekit base image. - Hide requirements-intel-after.txt during installRequirements (it used to 'pip install vllm'); install vllm's deps from a fresh git clone of vllm via 'uv pip install -r requirements/xpu.txt', swap stock triton for triton-xpu==3.7.0, then 'VLLM_TARGET_DEVICE=xpu uv pip install --no-deps .'. - requirements-intel.txt trimmed to LocalAI's direct deps (accelerate / transformers / bitsandbytes); torch-xpu, vllm, vllm_xpu_kernels and the rest come from upstream's xpu.txt during the source build. - requirements.txt: add pillow + charset-normalizer + chardet -- used by backend.py and missing on the Intel install profile. - run.sh: 'set -x' so backend startup is visible in container logs (the gRPC startup error path was previously opaque). Also adds a one-line docs example for engine_args.attention_backend under the vLLM section, since older XE-HPG GPUs (e.g. Arc A770) need TRITON_ATTN to bypass the cutlass path in vllm_xpu_kernels. Tested end-to-end on an Intel Arc A770 with Qwen2.5-0.5B-Instruct via LocalAI's /v1/chat/completions. Assisted-by: Claude:claude-opus-4-7 [Claude Code] Signed-off-by: Richard Palethorpe <io@richiejp.com> * feat(vllm): add multi-node data-parallel follower worker vLLM v1's multi-node story is one process per node sharing a DP coordinator over ZMQ -- the head runs the API server with data_parallel_size > 1 and followers run `vllm serve --headless ...` with matching topology. Today LocalAI can already configure DP on the head via the engine_args YAML map, but there's no way to bring up the follower nodes -- so the head sits waiting for ranks that never handshake. Add `local-ai p2p-worker vllm`, mirroring MLXDistributed's structural precedent (operator-launched, static config, no NATS placement). The worker: - Optionally self-registers with the frontend as an agent-type node tagged `node.role=vllm-follower` so it's visible in the admin UI and operators can scope ordinary models away via inverse selectors. - Resolves the platform-specific vllm backend via the gallery's "vllm" meta-entry (cuda*, intel-vllm, rocm-vllm, ...). - Runs vLLM as a child process so the heartbeat goroutine survives until vLLM exits; forwards SIGINT/SIGTERM so vLLM can clean up its ZMQ sockets before we tear down. - Validates --headless + --start-rank 0 is rejected (rank 0 is the head and must serve the API). Backend run.sh dispatches `serve` as the first arg to vllm's own CLI instead of LocalAI's backend.py gRPC server -- the follower speaks ZMQ directly to the head, there is no LocalAI gRPC on the follower side. Single-node usage is unchanged. Generalises the gallery resolution helper into findBackendPath() shared by MLX and vLLM workers; extracts ParseNodeLabels for the comma-separated label parsing both use. Ships with two compose recipes (`docker-compose.vllm-multinode.yaml` for NVIDIA, `docker-compose.vllm-multinode.intel.yaml` for Intel XPU/xccl) plus `tests/e2e/vllm-multinode/smoke.sh`. Both vendors are supported (NCCL for CUDA/ROCm, xccl for XPU) but mixed-vendor DP is not -- PyTorch's process group requires every rank to use the same collective backend, and NCCL/xccl/gloo don't interoperate. Out of scope (deferred): SmartRouter-driven placement of follower ranks via NATS backend.install events, follower log streaming through /api/backend-logs, tensor-parallel across nodes, disaggregated prefill via KVTransferConfig.

New `make test-e2e-vllm-multinode` target wires the docker build, backend extract, and ginkgo run together; BuildKit caches both images so re-runs only rebuild what changed. Tagged Label("VLLMMultinode") so the existing distributed suite isn't pulled along. Two pre-existing bugs surfaced by the test: 1. extract-backend-% (Makefile) failed for every backend, because all backend images end with `FROM scratch` and `docker create` rejects an image with no CMD/ENTRYPOINT. Fixed by passing --entrypoint=/run.sh -- the container is never started, only docker-cp'd, so the path doesn't have to exist; we just need anything that satisfies the daemon's create-time validation. 2. backend/python/vllm/run.sh's `serve` shortcut for the multi-node DP follower exec'd ${EDIR}/venv/bin/vllm directly, but uv bakes an absolute build-time shebang (`#!/vllm/venv/bin/python3`) that no longer resolves once the backend is relocated to BackendsPath. _makeVenvPortable's shebang rewriter only matches paths that already point at ${EDIR}, so the original shebang slips through unchanged. Fixed by exec-ing ${EDIR}/venv/bin/python with the script as an argument -- Python ignores the script's shebang in that case. The test fixture caps memory aggressively (max_model_len=512, VLLM_CPU_KVCACHE_SPACE=1, TORCH_COMPILE_DISABLE=1) so two CPU engines fit on a 32 GB box. TORCH_COMPILE_DISABLE is currently mandatory for cpu-vllm: torch._inductor's CPU-ISA probe runs even with enforce_eager=True and needs g++ on PATH, which the LocalAI runtime image doesn't ship -- to be addressed in a follow-up that bundles a toolchain in the cpu-vllm backend. Assisted-by: Claude:claude-opus-4-7 [Claude Code] Signed-off-by: Richard Palethorpe <io@richiejp.com> * feat(vllm): bundle a g++ toolchain in the cpu-vllm backend image torch._inductor's CPU-ISA probe (`cpu_model_runner.py:65 "Warming up model for the compilation"`) shells out to `g++` at vllm engine startup, regardless of `enforce_eager=True` -- the eager flag only disables CUDA graphs, not inductor's first-batch warmup. The LocalAI CPU runtime image (Dockerfile, unconditional apt list) does not ship build-essential, and the cpu-vllm backend image is `FROM scratch`, so any non-trivial inference on cpu-vllm crashes with: torch._inductor.exc.InductorError: InvalidCxxCompiler: No working C++ compiler found in torch._inductor.config.cpp.cxx: (None, 'g++') Bundling the toolchain in the CPU runtime image would bloat every non-vllm-CPU deployment and force a single GCC version on backends that may want clang or a different version. So this lives in the backend, gated to BUILD_TYPE=='' (the CPU profile). `package.sh` snapshots g++ + binutils + cc1plus + libstdc++ + libc6 (runtime + dev) + the math libs cc1plus links (libisl/libmpc/libmpfr/ libjansson) into ${BACKEND}/toolchain/, mirroring /usr/... layout. The unversioned binaries on Debian/Ubuntu are symlink chains pointing into multiarch packages (`g++` -> `g++-13` -> `x86_64-linux-gnu-g++-13`, the latter in `g++-13-x86-64-linux-gnu`), so the package list resolves both the version and the arch-triplet variant. Symlinks /lib -> usr/lib and /lib64 -> usr/lib64 are recreated under the toolchain root because Ubuntu's UsrMerge keeps them at /, and ld scripts (`libc.so`, `libm.so`) hardcode `/lib/...` paths that --sysroot re-roots into the toolchain. The unversioned `g++`/`gcc`/`cpp` symlinks are replaced with wrapper shell scripts that resolve their own location at runtime and pass `--sysroot=<toolchain>` and `-B <toolchain>/usr/lib/gcc/<triplet>/<ver>/` to the underlying versioned binary. That's how torch's bare `g++ foo.cpp -o foo` invocation finds cc1plus (-B), system headers (--sysroot), and the bundled libstdc++ (--sysroot, --sysroot is recursive into linker). `run.sh` adds the toolchain bin dir to PATH and the toolchain's shared-lib dir to LD_LIBRARY_PATH -- everything else (header search, linker search, executable search) is encapsulated in the wrappers. No-op for non-CPU builds, the dir doesn't exist there. The cpu-vllm image grows by ~217 MB. Tradeoff is acceptable -- cpu-vllm is already a niche profile (few users compared to GPU vllm) and the alternative is a backend that crashes at first inference unless the operator manually sets TORCH_COMPILE_DISABLE=1, which silently disables all torch.compile optimizations. Drops `TORCH_COMPILE_DISABLE=1` from tests/e2e/vllm-multinode -- the smoke now exercises the real compile path through the bundled toolchain. Test runtime is +20s for the warmup compile, still <90s end to end.

With `--extra-index-url` + `--index-strategy=unsafe-best-match` uv would pick those proxy URLs for ordinary PyPI packages — anthropic/openai/propcache/annotated-types — and fail when the proxy 503s. Master is hitting the same bug on its own l4t-vllm matrix entry. Switch the l4t13 install path to a pyproject.toml that marks the jetson-ai-lab index `explicit = true` and pins only torch, torchvision, torchaudio, flash-attn, and vllm to it via [tool.uv.sources]. uv won't consult the L4T mirror for anything else, so transitive deps fall back to PyPI as the default index — no exposure to the proxy 503s. `uv pip install -r requirements.txt` ignores [tool.uv.sources], so the l4t13 branch in install.sh now invokes `uv pip install --requirement pyproject.toml` directly, replacing the old requirements-l4t13*.txt files. Other BUILD_PROFILEs continue using libbackend.sh's installRequirements and never read pyproject.toml. Local resolution test (x86_64, dry-run) confirms uv hits the L4T index for torch and falls through to PyPI for everything else.

LocalAI [bot]	de83b72bb7	fix(distributed): orchestrator resilience — auto-upgrade routing, worker bind-wait, RAG-init crash, log spam (#9657) ... * fix(nodes/health): skip stale-marking already-offline nodes The health monitor re-emitted "Node heartbeat stale" + "Marking stale node offline" + MarkOffline on every cycle for nodes that were already in the offline (or unhealthy) state. For an operator-stopped node this flooded the logs with the same WARN+INFO pair every check interval. Skip the staleness branch when the node is already StatusOffline / StatusUnhealthy — the state is already what we'd write, so neither the log lines nor the DB update carry information. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(worker): wait for backend gRPC bind before replying to backend.install The backend supervisor used to wait up to 4s (20 × 200ms) for the backend's gRPC server to answer a HealthCheck, then log a warning and reply Success with the bind address anyway. On slower nodes (a Jetson Orin doing first-boot CUDA init, large CGO library load) the gRPC listener wasn't up yet, so the frontend's first LoadModel dial returned "connect: connection refused" and the operator chased a phantom network issue instead of a startup-timing one. Two changes: - Bump the readiness window to 30s. CUDA init on Orin/Thor first boot measures in seconds, not milliseconds. - On deadline-exceeded, stop the half-started process, recycle the port, and return an error with the backend's stderr tail. The frontend now gets a real failure with diagnostic context instead of a misleading ECONNREFUSED on a downstream dial. Process death during the wait window keeps its existing fast-fail path. Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(distributed): route auto-upgrade through BackendManager + bump LocalAGI/LocalRecall Two distributed-mode bugs that surfaced together in the orchestrator logs: 1. Auto-upgrade always failed with "backend not found". UpgradeChecker correctly routed CheckUpgrades through the active BackendManager (so the frontend aggregates worker state), but the auto-upgrade branch right below called gallery.UpgradeBackend directly with the frontend's SystemState. In distributed mode the frontend has no backends installed locally, so ListSystemBackends returned empty and Get(name) failed for every reported upgrade. Auto-upgrade now also goes through BackendManager.UpgradeBackend, which fans out to workers via NATS. 2. Embedding-load failure on a remote node crashed the orchestrator. When RAG init lazily called NewPersistentPostgresCollection and the remote embedding worker was unreachable, LocalRecall called os.Exit(1) inside the constructor, killing the orchestrator pod. LocalRecall now returns errors instead, LocalAGI surfaces them as a nil collection, and the existing RAGProviderFromState path returns (nil, nil, false) — the same code path the agent pool already takes when no RAG is configured. The orchestrator stays up; chat requests degrade to "no RAG available" until the embedding worker recovers.

An admin can install models, manage backends, edit configs and check status by chatting; the LLM calls tools like gallery_search, install_model, import_model_uri, list_installed_models, edit_model_config and surfaces the results. Same Go package powers two modes: pkg/mcp/localaitools/ NewServer(client, opts) builds an MCP server that registers the 19-tool admin catalog. The LocalAIClient interface has two impls: - inproc.Client — calls services directly (no HTTP loopback, no synthetic admin API key). Used in-process by the chat handler. - httpapi.Client — calls the LocalAI REST API. Used by the new `local-ai mcp-server --target=…` subcommand to control a remote LocalAI from a stdio MCP host. Tools and their embedded skill prompts are agnostic to which client backs them. Skill prompts are markdown files under prompts/, embedded via go:embed and assembled into the system prompt at server init. Wiring: - core/http/endpoints/mcp/localai_assistant.go — process-wide holder that spins up the in-memory MCP server once at Application start using paired net.Pipe transports, then reuses LocalToolExecutor (no fork) for every chat request that opts in. - core/http/endpoints/openai/chat.go — small branch ahead of the existing MCP block: when metadata.localai_assistant=true, defense-in-depth admin check + executor swap + system-prompt injection. All downstream tool dispatch is unchanged. - core/http/auth/{permissions,features}.go — adds FeatureLocalAIAssistant; gating happens at the chat handler entry plus admin-only `/api/settings`. - core/cli/{run.go,cli.go,mcp_server.go} — LOCALAI_DISABLE_ASSISTANT flag (runtime-toggleable via Settings, no restart), plus `local-ai mcp-server` stdio subcommand. - core/config/runtime_settings.go — `localai_assistant_enabled` runtime setting; the chat handler reads `DisableLocalAIAssistant` live at request entry. UI: - Home.jsx — prominent self-explanatory CTA card on first run ("Manage LocalAI by chatting"); collapses to a compact "Manage by chat" button in the quick-links row once used, persisted via localStorage. - Chat.jsx — admin-only "Manage" toggle in the chat header, "Manage mode" badge, dedicated empty-state copy, starter chips. - Settings.jsx — "LocalAI Assistant" section with the runtime enable toggle. - useChat.js — `localaiAssistant` flag on the chat schema; injects `metadata.localai_assistant=true` on requests when active. Distributed mode: the in-memory MCP server lives only on the head node; inproc.Client wraps already-distributed-aware services so installs propagate to workers via the existing GalleryService machinery. Documentation: `.agents/localai-assistant-mcp.md` is the contributor contract — when adding an admin REST endpoint, also add a LocalAIClient method, an inproc + httpapi impl, a tool registration, and a skill prompt update; the AGENTS.md index links to it. Out of scope (follow-ups): per-tool RBAC granularity for non-admin read-only access; streaming mcp_tool_progress for long installs; React Vitest rig for the UI changes.

Renaming any one required hand-editing every call site and risked code/test/prompt drift. This pulls them into typed constants: - pkg/mcp/localaitools/tools.go — Tool* constants for the 19 MCP tools, plus DefaultServerName. - pkg/mcp/localaitools/capability.go — typed Capability + constants for the capability tag set the LLM passes to list_installed_models. The type rides through LocalAIClient.ListInstalledModels and replaces the triplet of "embed"/"embedding"/"embeddings" with the single CapabilityEmbeddings. - pkg/mcp/localaitools/inproc/client.go — bytesPerMiB constant for the VRAMEstimate byte→MB conversion. - core/http/endpoints/mcp/tools.go — MetadataKeyLocalAIAssistant for the "localai_assistant" request-metadata key consumed by the chat handler. Tool registrations, the test catalog, the dispatch table, the validation fixtures, and the fake/stub clients all reference the constants. The embedded skill prompts under prompts/ keep their bare strings (go:embed markdown can't import Go constants); the existing TestPromptsContain SafetyAnchors guards the alignment. No behaviour change. All tests pass with -race.

A typo in any caller silently fell through to the runtime "must be 'enable' or 'disable'" check. Introduce core/services/modeladmin.Action (string alias) with ActionEnable, ActionDisable, ActionPin, ActionUnpin and a small Valid helper. The compiler now catches mismatches at every boundary; renames ripple through one source of truth. LocalAIClient.ToggleModelState/Pinned signatures change to take modeladmin.Action. The package is brand-new and unreleased so this is a free public-API tightening.

If the worker was paused or the buffer full, the chat-handler goroutine blocked forever — the LLM kept polling and the request leaked. Wrap the five sends in a sendModelOp/sendBackendOp helper that selects on ctx.Done() so a cancelled chat completion surfaces context.Canceled back to the LLM instead of hanging. Adds inproc/client_test.go with a pre-cancelled-ctx regression test on InstallModel; the helpers are shared so the same guarantee covers the other four call sites.

Hook into the existing signals.RegisterGracefulTerminationHandler chain (same pattern as core/http/endpoints/mcp/tools.go:770). - core/cli/mcp_server.go ran srv.Run with context.Background(); a Ctrl-C from the host (Claude Desktop, mcphost, npx inspector) or a SIGTERM from process supervision left the stdio loop reading from a closed pipe. Switch to signal.NotifyContext to surface the signal through ctx and let srv.Run drain. Assisted-by: Claude:claude-opus-4-7 [Read] [Edit] [Bash] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * fix(assistant): typed HTTPError + propagate prompt walk error The httpapi client detected "no such job" by substring-matching on the error string ("404", "could not find") — brittle to status-code formatting changes and to LocalAI fixing /models/jobs/:uuid to return a proper 404. Replace with a typed *HTTPError whose Is() method honours errors.Is(err, ErrHTTPNotFound). The 500-with-"could not find" branch stays as a transitional fallback documented in Is(). Same change covers ListNodes' 404 fallback for the /api/nodes endpoint. Adds httptest tests for both 404 and the legacy 500 path, plus a direct errors.Is exposure test so external callers (the standalone stdio CLI host) can match without re-string-parsing. Also tightens prompts.SystemPrompt: panic when fs.WalkDir on the embedded FS fails. The only realistic cause is a build-time //go:embed misconfiguration; serving an empty system prompt to the LLM is much worse than crashing init. TestSystemPromptIncludesAllEmbeddedFiles catches regressions in CI.

A crash mid-write left the destination truncated and the model unloadable until manual repair. Pre-existing behaviour inherited from the original endpoint handlers — fix once now that there's a single helper. Adds writeFileAtomic: writes to a sibling temp file, chmods, syncs via Close(), then os.Rename. Same-directory temp keeps the rename atomic on the same filesystem; cleanup runs on every error path so stray temps don't accumulate. No new dependency. Applied to: - ConfigService.PatchConfig - ConfigService.EditYAML (both rename and in-place branches) - mutateYAMLBoolFlag (drives ToggleState + TogglePinned) atomic_test.go covers the happy path plus a read-only-dir failure case that asserts the original file is preserved (skipped on Windows where the chmod trick is POSIX-specific).

All five methods that used to return it are wired to modeladmin helpers since the Phase B commit; the package var is dead. - Annotate httpapi.Client.GetModelConfig as a known stub. LocalAI's /models/edit/:name returns rendered HTML, not JSON, so the standalone CLI's get_model_config tool surfaces a clear error to the LLM. A future JSON-only /api/models/config-yaml/:name endpoint is tracked in the agent contract; FIXME points at it. - Extend `.agents/localai-assistant-mcp.md` with a "Code conventions" section that documents the audit-driven rules: tool/Capability/Action constants, errors.Is over substring matching, ctx-aware channel sends, atomic writes, and graceful shutdown. Refresh the file map so it lists tools.go and capability.go and drops the removed tools_bootstrap.go. The tools_models.go diff is a comment-only change explaining why the ModelName empty-string check stays at the tool layer (consistency across LocalAIClient implementations, since the SDK schema validator only enforces presence, not non-empty). Assisted-by: Claude:claude-opus-4-7 [Read] [Edit] [Bash] Signed-off-by: Ettore Di Giacinto <mudler@localai.io> * test(assistant): convert test files to ginkgo + gomega The repo convention (per core/http/endpoints/localai/*_test.go, core/gallery/**, etc.) is Ginkgo v2 with Gomega assertions. The tests I introduced for the assistant feature used vanilla testing.T, which made them stand out and stripped the BDD structure the rest of the suite relies on. Convert every test file in the assistant scope to Ginkgo: pkg/mcp/localaitools/ dto_test.go — Describe("DTOs round-trip through JSON") prompts_test.go — Describe("SystemPrompt assembler") server_test.go — Describe("Server tool catalog"), Describe("Tool dispatch"), Describe("Tool error surfacing"), Describe("Argument validation"), Describe("Concurrent tool calls") parity_test.go — Describe("LocalAIClient parity"), hosts the suite's single RunSpecs (the file is package localaitools_test so it can import httpapi without an import cycle; Ginkgo aggregates Describes from both the internal and external test packages into one run). httpapi/client_test.go — Describe("httpapi.Client against the LocalAI admin REST surface"), Describe("ErrHTTPNotFound"), Describe("Bearer token") inproc/client_test.go — Describe("inproc.Client cancellation") core/services/modeladmin/ config_test.go — Describe("ConfigService") with sub-Describes for GetConfig, PatchConfig, EditYAML state_test.go — Describe("ConfigService.ToggleState") pinned_test.go — Describe("ConfigService.TogglePinned") atomic_test.go — Describe("writeFileAtomic") core/http/endpoints/mcp/ localai_assistant_test.go — Describe("LocalAIAssistantHolder") Each package gets a `*_suite_test.go` with the standard `RegisterFailHandler(Fail) + RunSpecs(t, "...")` boilerplate. Helpers that previously took *testing.T (newTestService, writeModelYAML, readMap, sortedStrings, sortGalleries, etc.) drop the *T receiver and use Gomega Expectations directly. tmp dirs come from GinkgoT().TempDir(). No semantic change to test coverage — every original assertion has a direct Gomega counterpart. All suites pass with -race.

If a contributor adds an admin REST endpoint without an MCP tool, or a tool without a matching httpapi route, both surfaces silently diverge. Add a coverage test plus stronger docs: - pkg/mcp/localaitools/coverage_test.go introduces a hand-maintained toolToHTTPRoute map: every Tool* constant must list the REST endpoint the httpapi.Client hits (or "(none)" with a documented reason). Two Ginkgo specs assert the map and the published catalog stay in sync — one fails when a Tool is added without a route entry, the other fails when a route entry references a tool that no longer exists. Verified by removing the ToolDeleteModel entry locally; the test fired with a clear message pointing the contributor at the file. Deliberate non-test: we don't enumerate live admin REST routes from here. Walking the route registry requires booting Application; parsing core/http/routes/localai.go is brittle. The "new admin REST endpoint → MCP tool" direction stays a PR checklist item — see below. - AGENTS.md gets a new Quick Reference bullet that calls out the rule and points at the test by name. - .agents/api-endpoints-and-auth.md tightens the existing "Companion: MCP admin tool surface" subsection from "if useful, consider..." to "MUST be considered, with three concrete outcomes (tool added, deliberately skipped with documented reason, or forgot — which breaks the contract)". Adds a checklist item at the bottom of the file's authoritative checklist.

Replace the duplicates with the canonical types so the LLM-visible wire format stays aligned with the rest of LocalAI by construction (no parallel structs to keep in sync). Removed (and the canonical type now used by the LocalAIClient interface): localaitools.Gallery → config.Gallery localaitools.GalleryModelHit → gallery.Metadata localaitools.VRAMEstimate → vram.EstimateResult Tightened scope: localaitools.Backend → kept, but reduced to {Name, Installed}. ListKnownBackends now returns []schema.KnownBackend (the canonical type already used by REST /backends/known). Kept with documented rationale: localaitools.JobStatus — galleryop.OpStatus has Error error which marshals to "{}". JobStatus is the JSON-friendly mirror. localaitools.Node — nodes.BackendNode carries gorm internals + token hash; we expose only the LLM-relevant fields. ImportModelURIRequest/Response — schema.ImportModelRequest and GalleryResponse are wire-shaped, mine are LLM-shaped (BackendPreference flat, AmbiguousBackend exposed). Side wins: - Drop bytesPerMiB; vram.EstimateResult already carries human-readable display strings (size_display, vram_display) the LLM uses directly. - Drop the handler-private vramEstimateRequest in core/http/endpoints/localai/vram.go and bind directly into modeladmin.VRAMRequest (now JSON-tagged). Both clients pass through these types now where possible (e.g. ListGalleries in inproc.Client is a one-liner returning AppConfig.Galleries; httpapi.Client.GallerySearch decodes straight into []gallery.Metadata). All tests green with -race.

Pull them into pkg/mcp/localaitools/httpapi/routes.go: static paths as package-private constants, dynamic paths as small builders that handle url.PathEscape on segment values. No behaviour change. Drops the now-unused net/url import from client.go since path escaping moved into routes.go alongside the path it applies to. Local-only by design: the server-side registrations in core/http/routes/localai.go remain bare strings. Sharing constants across the pkg/ ↔ core/ boundary would invert the layering today; the existing Tool↔REST drift-detector in coverage_test.go is the safety net for that direction.

Ettore Di Giacinto	3948b580d2	fix(distributed): worker stopBackend/isRunning resolve bare modelID to replica keys ... PR #9583 changed the supervisor's process map key from `modelID` to `modelID#replicaIndex`, but the NATS lifecycle handlers kept passing the bare modelID: * `backend.stop` (subscribeLifecycleEvents): `s.stopBackend(req.Backend)` → `s.processes["Qwen3.6-..."]` missed (actual key is "...#0") → silent no-op. Admin "Unload model" clicks released VRAM via model.unload but left the gRPC process alive on its old port. Subsequent chats hit installBackend, found the leftover process, reused its address — and the UI reported "no models loaded" while the model kept responding. * `backend.delete` (subscribeLifecycleEvents): same map miss in `isRunning(req.Backend)` and `s.stopBackend(req.Backend)` — admin "Delete backend" deleted the binary while the process was still serving traffic. Add `resolveProcessKeys(id)`: exact match if `id` is a full processKey (stopAllBackends iterates the map and passes its own keys); prefix-match if `id` is bare (NATS handlers); empty if `id` contains `#` but doesn't match (no spurious fallback when the caller was explicit). stopBackend and isRunning now call it; stopBackend gets a new stopBackendExact helper for per-key cleanup. TDD: regression test fails without the fix (resolveProcessKeys doesn't exist; map lookup by bare name returns nothing). Tests pass post-fix. Reproduced live: registry row count was 0 for the model the user "Unloaded", chat still served by the leftover worker process. SmartRouter behavior is correct in itself — it falls through to scheduleAndLoad when no row exists; the bug was that the leftover process corrupted the install path.

Ettore Di Giacinto	6b63b47f61	feat(distributed): support multiple replicas of one model on the same node (#9583) ... * feat(distributed): support multiple replicas of one model on the same node The distributed scheduler implicitly assumed `(node_id, model_name)` was unique, but the schema didn't enforce it and the worker keyed all gRPC processes by model name alone. With `MinReplicas=2` against a single worker, the reconciler "scaled up" every 30s but the registry never advanced past 1 row — the worker re-loaded the model in-place every tick until VRAM fragmented and the gRPC process died. This change introduces multi-replica-per-node as a first-class concept, with capacity-aware scheduling, a circuit breaker, and VRAM soft-reservation. Operators can declare per-node capacity via the worker flag `--max-replicas-per-model` (mirrored as auto-label `node.replica-slots=N`) or override per-node from the UI. * Schema: BackendNode gains MaxReplicasPerModel (default 1) and ReservedVRAM. NodeModel gains ReplicaIndex (composite with node_id + model_name). ModelSchedulingConfig gains UnsatisfiableUntil/Ticks for the reconciler circuit breaker. * Registry: replica_index threaded through SetNodeModel, RemoveNodeModel, IncrementInFlight, DecrementInFlight, TouchNodeModel, GetNodeModel, SetNodeModelLoadInfo and the InFlightTrackingClient. New helpers: CountReplicasOnNode, NextFreeReplicaIndex (with ErrNoFreeSlot), RemoveAllNodeModelReplicas, FindNodesWithFreeSlot, ClusterCapacityForModel, ReserveVRAM/ReleaseVRAM (atomic UPDATE with ErrInsufficientVRAM), and the unsatisfiable-flag CRUD. * Worker: processKey now `<modelID>#<replicaIndex>` so concurrent loads of the same model land on distinct ports. Adds CLI flag --max-replicas-per-model (env LOCALAI_MAX_REPLICAS_PER_MODEL, default 1) and emits the auto-label. * Router: scheduleNewModel filters candidates by free slot, allocates the replica index, and soft-reserves VRAM before installing the backend. evictLRUAndFreeNode now deletes the targeted row by ID instead of all replicas of the model on the node — fixes a latent bug where evicting one replica orphaned its siblings. * Reconciler: caps scale-up at ClusterCapacityForModel so a misconfig (MinReplicas > capacity) doesn't loop forever. After 3 consecutive ticks of capacity==0 it sets UnsatisfiableUntil for a 5m cooldown and emits a warning. ClearAllUnsatisfiable fires from Register, ApproveNode, SetNodeLabel(s), RemoveNodeLabel and UpdateMaxReplicasPerModel so a new node joining or label changes wake the reconciler immediately. scaleDownIdle removes highest-replica-index first to keep slots compact. * Heartbeat resets reserved_vram to 0 — worker is the source of truth for actual free VRAM; the reservation is only for the in-tick race window between two scheduling decisions. * Probe path (reconciler.probeLoadedModels and health.doCheckAll) now pass the row's replica_index to RemoveNodeModel so an unreachable replica doesn't orphan healthy siblings. * Admin override: PUT /api/nodes/:id/max-replicas-per-model sets a sticky override (preserved across worker re-registration). DELETE clears the override so the worker's flag applies again on next register. Required because Kong defaults the worker flag to 1, so every worker restart would have silently reverted the UI value. * React UI: always-visible slot badge on the node row (muted at default 1, accented when >1); inline editor in the expanded drawer with pencil-to-edit, Save/Cancel, Esc/Enter, "(override)" indicator when the value is admin-set, and a "Reset" button to hand control back to the worker. Soft confirm when shrinking the cap below the count of loaded replicas. Scheduling rules table gets an "Unsatisfiable until HH:MM" status badge surfacing the cooldown. * node.replica-slots filtered out of the labels strip on the row to avoid duplicating the slot badge. 23 new Ginkgo specs (registry, reconciler, inflight, health) cover: multi-replica row independence, RemoveNodeModel of one replica preserving siblings, NextFreeReplicaIndex slot allocation including ErrNoFreeSlot, capacity-gated scale-up with circuit breaker tripping and recovery on Register, scheduleDownIdle ordering, ClusterCapacity math, ReserveVRAM admission gating, Heartbeat reset, override survival across worker re-registration, and ResetMaxReplicasPerModel handing control back. Plus 8 stdlib tests for the worker processKey / CLI / auto-label. Closes the flap reproduced on Qwen3.6-35B against the nvidia-thor worker (single 128 GiB node, MinReplicas=2): the reconciler now caps the scale-up at the cluster's actual capacity instead of looping.

Changing it here makes it a sticky admin override that survives worker restarts." → "Saved values stick across worker restarts.") and the override-state copy similarly compressed. The full mechanic is no longer needed in the UI — the override pill carries the meaning and the docs cover the rest. * Node row actions migrated from an inline cluster of icon buttons (Drain / Resume / Trash) to the kebab ActionMenu used by /manage for per-row model actions, so dense Nodes tables stay clean. Approve stays as a prominent primary button — it's a stateful admission gate, not a routine action, and elevating it matches how /manage surfaces install-time decisions outside the menu. * The expanded drawer's Labels section now filters node.replica-slots out of the editable label list. The label is owned by the Capacity editor above; surfacing it again as an editable label invited confusion (the Capacity save would clobber any direct edit).

The scheduling rule form wrapped its mode toggle as two 50%-width filled buttons that competed visually with the actual primary action. * Drawer: collapse three rarely-touched config zones (Capacity, Backends, Labels) into one `<details>` "Manage" disclosure (closed by default) with small uppercase eyebrow labels for each zone instead of parallel h4 sub-headings. Loaded Models stays as the at-a-glance headline with a single-line empty hint instead of a boxed empty state. CapacityEditor renders flat (no filled background) — the Manage disclosure provides framing. * Scheduling form: replace the chunky 50%-width button-tabs with the project's existing `.segmented` control (icon + label, sized to content). Mode hint becomes a single tied line below. Fields stack vertically with helper text under inputs and a hairline divider above the right-aligned Save / Cancel. The empty drawer collapses from ~5 stacked sections (~280px tall) to two lines (~80px). The scheduling form now reads as a designed dialog instead of raw building blocks.

The form's input was also a comma-separated string that operators were getting wrong. * Extract <KeyValueChips> as a fully controlled chip-builder. Parent owns the map and decides what onAdd/onRemove does — form state for the scheduling form, API calls for the live drawer Labels editor. Same visuals everywhere; one component to change when polish needs apply. * Replace the comma-separated Node Selector text input with KeyValueChips. Operators were copying syntax from docs and missing commas; the chip vocabulary makes the key=value structure self-documenting. * Add <ReplicaInput>: numeric input + quick-pick preset chips for Min/Max replicas. Picked over a slider because replica counts are exact specs derived from VRAM math (operator decision, not a fuzzy estimate). The chips give one-click access to common values (1/2/3/4 for Min, 0=no-limit/2/4/8 for Max) without the slider's special-value problem (MaxReplicas=0 is categorical, not a position on a continuum). * Drop the now-unused labelInputs state in the Nodes page (the inline label editor's per-node draft state lived there and is now owned by KeyValueChips).

All updated to pass replicaIndex=0 — these tests don't exercise multi-replica behavior, they just need to compile against the new signatures. The chip-builder tests in core/services/nodes/ already cover the multi-replica logic. * core/http/react-ui/e2e/nodes-per-node-backend-actions.spec.js — the drawer's distill refactor moved Backends inside a "Manage" <details> disclosure that's collapsed by default. The test helper expanded the node row but never opened Manage, so the per-node backend table was never in the DOM. Helper now clicks `.node-manage > summary` after expanding the row.

Ettore Di Giacinto	551ebdb57a	fix(distributed): correct VRAM/RAM reporting on NVIDIA unified-memory hosts (#9545) ... Workers on NVIDIA unified-memory hardware (DGX Spark / GB10, Jetson AGX Thor, Jetson Orin/Xavier/Nano) were reporting `available_vram=0` back to the frontend, so the Nodes UI showed the node as fully used even when most of the unified memory was actually free. Three causes addressed: * `isTegraDevice` only matched `/sys/devices/soc0/family == "Tegra"`. DGX Spark (SBSA) reports JEDEC codes there instead — `jep106:0426` for the NVIDIA manufacturer — so the Tegra/unified-memory fallback never ran. Renamed to `isNVIDIAIntegratedGPU` and extended to also match `jep106:0426[:*]` via `/sys/devices/soc0/soc_id`. * The unified-iGPU code defaulted the device name to `"NVIDIA Jetson"` when `/proc/device-tree/model` was missing. That's what happens for Thor inside a docker container, and always on DGX Spark. New `nvidiaIntegratedGPUName` resolves via dt-model → `/sys/devices/soc0/machine` → `soc_id` lookup (`jep106:0426:8901` → `"NVIDIA GB10"`) so the Nodes UI labels the box correctly. * Worker heartbeat sent `available_vram=0` (or total-as-available) when VRAM usage was momentarily unknown — e.g. when `nvidia-smi` intermittently failed with `waitid: no child processes` under containers without `--init`. Each such heartbeat overwrote the DB and made the UI flip to "fully used". `heartbeatBody` now omits `available_vram` in that case so the DB keeps its last good value. Also updates the commented GPU blocks in both compose files with `NVIDIA_DRIVER_CAPABILITIES=compute,utility`, `capabilities: [gpu, utility]`, and `init: true`, and documents the requirement in the distributed-mode and nvidia-l4t pages. Without `utility`, NVML/`nvidia-smi` are absent inside the container, which is what put the DGX Spark worker into the buggy fallback in the first place. Detection verified on live hardware (dgx.casa / GB10 and 192.168.68.23 / Thor) by running a cross-compiled probe of the new helpers on both host and inside the worker container.

Russell Sim	02bb715c0a	fix(distributed): pass ExternalURI through NATS backend install (#9446) ... When installing a backend with a custom OCI URI in distributed mode, the URI was captured in ManagementOp.ExternalURI by the HTTP handler but never forwarded to workers. BackendInstallRequest had no URI field, so workers fell through to the gallery lookup and failed with "no backend found with name <custom-name>". Add URI/Name/Alias fields to BackendInstallRequest and thread them from ManagementOp through DistributedBackendManager.InstallBackend() and the RemoteUnloaderAdapter. On the worker side, route to InstallExternalBackend when URI is set instead of InstallBackendFromGallery. Update all remaining InstallBackend call sites (UpgradeBackend, reconciler pending-op drain, router auto-install) to pass empty strings for the new params.

Ettore Di Giacinto	75a63f87d8	feat(distributed): sync state with frontends, better backend management reporting (#9426) ... * fix(distributed): detect backend upgrades across worker nodes Before this change `DistributedBackendManager.CheckUpgrades` delegated to the local manager, which read backends from the frontend filesystem. In distributed deployments the frontend has no backends installed locally — they live on workers — so the upgrade-detection loop never ran and the UI silently never surfaced upgrades even when the gallery advertised newer versions or digests. Worker-side: NATS backend.list reply now carries Version, URI and Digest for each installed backend (read from metadata.json). Frontend-side: DistributedBackendManager.ListBackends aggregates per-node refs (name, status, version, digest) instead of deduping, and CheckUpgrades feeds that aggregation into gallery.CheckUpgradesAgainst — a new entrypoint factored out of CheckBackendUpgrades so both paths share the same core logic. Cluster drift policy: when per-node version/digest tuples disagree, the backend is flagged upgradeable regardless of whether any single node matches the gallery, and UpgradeInfo.NodeDrift enumerates the outliers so operators can see *why* it is out of sync. The next upgrade-all realigns the cluster. Tests cover: drift detection, unanimous-match (no upgrade), and the empty-installed-version path that the old distributed code silently missed. * feat(ui): surface backend upgrades in the System page The System page (Manage.jsx) only showed updates as a tiny inline arrow, so operators routinely missed them. Port the Backend Gallery's upgrade UX so System speaks the same visual language: - Yellow banner at the top of the Backends tab when upgrades are pending, with an "Upgrade all" button (serial fan-out, matches the gallery) and a "Updates only" filter toggle. - Warning pill (↑ N) next to the tab label so the count is glanceable even when the banner is scrolled out of view. - Per-row labeled "Upgrade to vX.Y" button (replaces the icon-only button that silently flipped semantics between Reinstall and Upgrade), plus an "Update available" badge in the new Version column. - New columns: Version (with upgrade + drift chips), Nodes (per-node attribution badges for distributed mode, degrading to a compact "on N nodes · M offline" chip above three nodes), Installed (relative time). - System backends render a "Protected" chip instead of a bare "—" so rows still align and the reason is obvious. - Delete uses the softer btn-danger-ghost so rows don't scream red; the ConfirmDialog still owns the "are you sure". The upgrade checker also needed the same per-worker fix as the previous commit: NewUpgradeChecker now takes a BackendManager getter so its periodic runs call the distributed CheckUpgrades (which asks workers) instead of the empty frontend filesystem. Without this the /api/backends/ upgrades endpoint stayed empty in distributed mode even with the protocol change in place. New CSS primitives — .upgrade-banner, .tab-pill, .badge-row, .cell-stack, .cell-mono, .cell-muted, .row-actions, .btn-danger-ghost — all live in App.css so other pages can adopt them without duplicating styles. * feat(ui): polish the Nodes page so it reads like a product The Nodes page was the biggest visual liability in distributed mode. Rework the main dashboard surfaces in place without changing behavior: StatCards: uniform height (96px min), left accent bar colored by the metric's semantic (success/warning/error/primary), icon lives in a 36x36 soft-tinted chip top-right, value is left-aligned and large. Grid auto-fills so the row doesn't collapse on narrow viewports. This replaces the previous thin-bordered boxes with inconsistent heights. Table rows: expandable rows now show a chevron cue on the left (rotates on expand) so users know rows open. Status cell became a dedicated chip with an LED-style halo dot instead of a bare bullet. Action buttons gained labels — "Approve", "Resume", "Drain" — so the icons aren't doing all the semantic work; the destructive remove action uses the softer btn-danger-ghost variant so rows don't scream red, with the ConfirmDialog still owning the real "are you sure". Applied cell-mono/cell-muted utility classes so label chips and addresses share one spacing/font grammar instead of re-declaring inline styles everywhere. Expanded drawer: empty states for Loaded Models and Installed Backends now render as a proper drawer-empty card (dashed border, icon, one-line hint) instead of a plain muted string that read like broken formatting. Tabs: three inline-styled buttons became the shared .tab class so they inherit focus ring, hover state, and the rest of the design system — matches the System page. "Add more workers" toggle turned into a .nodes-add-worker dashed-border button labelled "Register a new worker" (action voice) instead of a chevron + muted link that operators kept mistaking for broken text. New shared CSS primitives carry over to other pages: .stat-grid + .stat-card, .row-chevron, .node-status, .drawer-empty, .nodes-add-worker. * feat(distributed): durable backend fan-out + state reconciliation Two connected problems handled together: 1) Backend delete/install/upgrade used to silently skip non-healthy nodes, so a delete during an outage left a zombie on the offline node once it returned. The fan-out now records intent in a new pending_backend_ops table before attempting the NATS round-trip. Currently-healthy nodes get an immediate attempt; everyone else is queued. Unique index on (node_id, backend, op) means reissuing the same operation refreshes next_retry_at instead of stacking duplicates. 2) Loaded-model state could drift from reality: a worker OOM'd, got killed, or restarted a backend process would leave a node_models row claiming the model was still loaded, feeding ghost entries into the /api/nodes/models listing and the router's scheduling decisions. The existing ReplicaReconciler gains two new passes that run under a fresh KeyStateReconciler advisory lock (non-blocking, so one wedged frontend doesn't freeze the cluster): - drainPendingBackendOps: retries queued ops whose next_retry_at has passed on currently-healthy nodes. Success deletes the row; failure bumps attempts and pushes next_retry_at out with exponential backoff (30s → 15m cap). ErrNoResponders also marks the node unhealthy. - probeLoadedModels: gRPC-HealthChecks addresses the DB thinks are loaded but hasn't seen touched in the last probeStaleAfter (2m). Unreachable addresses are removed from the registry. A pluggable ModelProber lets tests substitute a fake without standing up gRPC. DistributedBackendManager exposes DeleteBackendDetailed so the HTTP handler can surface per-node outcomes ("2 succeeded, 1 queued") to the UI in a follow-up commit; the existing DeleteBackend still returns error-only for callers that don't care about node breakdown. Multi-frontend safety: the state pass uses advisorylock.TryWithLockCtx on a new key so N frontends coordinate — the same pattern the health monitor and replica reconciler already rely on. Single-node mode runs both passes inline (adapter is nil, state drain is a no-op). Tests cover the upsert semantics, backoff math, the probe removing an unreachable model but keeping a reachable one, and filtering by probeStaleAfter. * feat(ui): show cluster distribution of models in the System page When a frontend restarted in distributed mode, models that workers had already loaded weren't visible until the operator clicked into each node manually — the /api/models/capabilities endpoint only knew about configs on the frontend's filesystem, not the registry-backed truth. /api/models/capabilities now joins in ListAllLoadedModels() when the registry is active, returning loaded_on[] with node id/name/state/status for each model. Models that live in the registry but lack a local config (the actual ghosts, not recovered from the frontend's file cache) still surface with source="registry-only" so operators can see and persist them; without that emission they'd be invisible to this frontend. Manage → Models replaces the old Running/Idle pill with a distribution cell that lists the first three nodes the model is loaded on as chips colored by state (green loaded, blue loading, amber anything else). On wider clusters the remaining count collapses into a +N chip with a title-attribute breakdown. Disabled / single-node behavior unchanged. Adopted models get an extra "Adopted" ghost-icon chip with hover copy explaining what it means and how to make it permanent. Distributed mode also enables a 10s auto-refresh and a "Last synced Xs ago" indicator next to the Update button so ghost rows drop off within one reconcile tick after their owning process dies. Non-distributed mode is untouched — no polling, no cell-stack, same old Running/Idle. * feat(ui): NodeDistributionChip — shared per-node attribution component Large clusters were going to break the Manage → Backends Nodes column: the old inline logic rendered every node as a badge and would shred the layout at >10 workers, plus the Manage → Models distribution cell had copy-pasted its own slightly-different version. NodeDistributionChip handles any cluster size with two render modes: - small (≤3 nodes): inline chips of node names, colored by health. - large: a single "on N nodes · M offline · K drift" summary chip; clicking opens a Popover with a per-node table (name, status, version, digest for backends; name, status, state for models). Drift counting mirrors the backend's summarizeNodeDrift so the UI number matches UpgradeInfo.NodeDrift. Digests are truncated to the docker-style 12-char form with the full value preserved in the title. Popover is a new general-purpose primitive: fixed positioning anchored to the trigger, flips above when there's no room below, closes on outside-click or Escape, returns focus to the trigger. Uses .card as its surface so theming is inherited. Also useful for a future labels-editor popup and the user menu. Manage.jsx drops its duplicated inline Nodes-column + loaded_on cell and uses the shared chip with context="backends" / "models" respectively. Delete code removes ~40 lines of ad-hoc logic. * feat(ui): shared FilterBar across the System page tabs The Backends gallery had a nice search + chip + toggle strip; the System page had nothing, so the two surfaces felt like different apps. Lift the pattern into a reusable FilterBar and wire both System tabs through it. New component core/http/react-ui/src/components/FilterBar.jsx renders a search input, a role="tablist" chip row (aria-selected for a11y), and optional toggles / right slot. Chips support an optional `count` which the System page uses to show "User 3", "Updates 1" etc. System Models tab: search by id or backend; chips for All/Running/Idle/Disabled/Pinned plus a conditional Distributed chip in distributed mode. "Last synced" + Update button live in the right slot. System Backends tab: search by name/alias/meta-backend-for; chips for All/User/System/Meta plus conditional Updates / Offline-nodes chips when relevant. The old ad-hoc "Updates only" toggle from the upgrade banner folded into the Updates chip — one source of truth for that filter. Offline chip only appears in distributed mode when at least one backend has an unhealthy node, so the chip row stays quiet on healthy clusters. Filter state persists in URL query params (mq/mf/bq/bf) so deep links and tab switches keep the operator's filter context instead of resetting every time. Also adds an "Adopted" distribution path: when a model in /api/models/capabilities carries source="registry-only" (discovered on a worker but not configured locally), the Models tab shows a ghost chip labelled "Adopted" with hover copy explaining how to persist it — this is what closes the loop on the ghost-model story end-to-end.	2026-04-19 17:55:53 +02:00
