That is the same seam Valkey uses for RESP. vector_store_id names the Atlas Search index, matching Valkey, with the database and collection supplied through litellm_params. pymongo lives in a new optional `mongodb` extra and is imported lazily, so the base install still pulls no MongoDB driver. The floor is 4.17 because that is where dnspython became a core dependency instead of the `srv` extra, and Atlas issues mongodb+srv:// URIs that will not resolve without it.

store config 65 cases across pipeline construction, response mapping, parameter validation, client caching, and driver-error translation. The sad-path cases assert on the message the caller actually sees, since a vector search that fails quietly returns an empty result set rather than an error. --- .../test_mongodb_transformation.py |

[PATCH 10/66] fix(vector_stores): turn MongoDB's silent misconfiguration failures into errors Driving the sad path against a live Atlas cluster showed four cases returning an empty result set instead of failing: a missing index, a missing database, a missing collection, and the async path for all three. $vectorSearch reports none of these as errors, so a misconfigured store looked exactly like a query that matched nothing, which is the worst shape for this to fail in. An empty result set is now checked against the index catalogue, which does report all three correctly, and a store that cannot work says so. The check costs one extra round trip and only on the empty path, so a search that returned hits is unaffected. Atlas also reports a wrong vector path and a dimension mismatch under the same error code. Both previously surfaced as "index not found", which sent the reader looking in the wrong place; they are now told apart and each names the setting that is actually wrong. --- litellm/llms/mongodb/common_utils.py | 29 +++- .../mongodb/vector_stores/transformation.py | 38 ++++- .../test_mongodb_transformation.py | 153 +++++++++++++++++- 3 files changed, 210 insertions(+), 10 deletions(-) diff --git a/litellm/llms/mongodb/common_utils.py b/litellm/llms/mongodb/common_utils.py index 7f26eadb08f..2571821381a 100644 --- a/litellm/llms/mongodb/common_utils.py +++ b/litellm/llms/mongodb/common_utils.py @@ -105,6 +105,24 @@ def _index_hint(index_name: str, database: str, collection: str) -> str: ) +def missing_index_error(index_name: str, database: str, collection: str) -> ValueError: + """$vectorSearch against a missing index, database or collection returns zero documents + instead of failing, so an empty result set is checked against the index catalogue and + turned into this rather than being reported as 'no matches'.""" + return ValueError( + f"{_index_hint(index_name, database, collection)} A vector search against a database, " + "collection or index that does not exist returns no results rather than an error, so this " + "was reported as an empty result set by MongoDB." + ) + + +def index_not_ready_error(index_name: str, database: str, collection: str, status: str) -> ValueError: + return ValueError( + f"The Atlas Vector Search index '{index_name}' on '{database}.{collection}' is not queryable " + f"yet; its status is {status}.

strings in management responses A MongoDB vector store's whole credential is its connection string, and mongodb+srv://:@ embeds the database password. None of the masker's default patterns (api_key, secret, token, credential) match a key named mongodb_connection_string, so /vector_store/list and /vector_store/info returned it verbatim to every caller that can read a vector store. SensitiveDataMasker gains extra_sensitive_patterns, which unions onto the defaults instead of replacing them, and the vector-store redactor adds "connection" so the URI is masked while mongodb_database, mongodb_collection and the field names stay readable. --- .../sensitive_data_masker.py | 42 +++++++++++-------- .../management_endpoints.py | 5 ++- .../test_sensitive_data_masker.py | 19 +++++++++ .../test_vector_store_endpoints.py | 36 ++++++++++++++++ 4 files changed, 84 insertions(+), 18 deletions(-) diff --git a/litellm/litellm_core_utils/sensitive_data_masker.py b/litellm/litellm_core_utils/sensitive_data_masker.py index 3d60c1bda12..3b0806ab069 100644 --- a/litellm/litellm_core_utils/sensitive_data_masker.py +++ b/litellm/litellm_core_utils/sensitive_data_masker.py @@ -6,33 +6,41 @@ from pydantic import BaseModel from litellm.constants import DEFAULT_MAX_RECURSE_DEPTH_SENSITIVE_DATA_MASKER +_DEFAULT_SENSITIVE_PATTERNS: Final = frozenset( + { + "password", + "secret", + "key", + "token", + "auth", + "authorization", + "credential", + # Plural form: Vertex uses ``vertex_credentials``; segment-exact + # matching otherwise misses it because "credential" != "credentials". + "credentials", + "access", + "private", + "certificate", + "fingerprint", + "tenancy", + } +) + + class SensitiveDataMasker: def __init__( self, sensitive_patterns: set[str] | None = None, + extra_sensitive_patterns: set[str] | None = None, non_sensitive_overrides: set[str] | None = None, visible_prefix: int = 4, visible_suffix: int = 4, mask_char: str = "*", mask_short_values: bool = True, ): - self.sensitive_patterns = sensitive_patterns or { - "password", - "secret", - "key", - "token", - "auth", - "authorization", - "credential", - # Plural form: Vertex uses ``vertex_credentials``; segment-exact - # matching otherwise misses it because "credential" != "credentials". - "credentials", - "access", - "private", - "certificate", - "fingerprint", - "tenancy", - } + self.sensitive_patterns = (sensitive_patterns or _DEFAULT_SENSITIVE_PATTERNS) | ( + extra_sensitive_patterns or frozenset() + ) # If any key segment matches one of these, the key is not considered sensitive # even if it also matches a sensitive pattern.

CPython recycles those ids so aggressively that a fresh event loop nearly always lands on the id of one already collected, measured at 37 of 40 rounds, so the cache handed the new loop an AsyncMongoClient bound to a closed loop and every operation on it raised "Event loop is closed". The entry now carries a weak reference to the loop it was built on and a hit only counts when that reference still points at the running loop, so a recycled id misses and builds a fresh client. A stale entry can also be replaced once the cache is full, which the old size check prevented. pymongo's own client keeps its loop alive, which is why the sync proxy path never saw this; a script calling asyncio.run() per search, or a test suite with a loop per test, does. --- litellm/llms/mongodb/common_utils.py | 20 ++++++--- .../test_mongodb_transformation.py | 43 +++++++++++++++++++ 2 files changed, 57 insertions(+), 6 deletions(-) diff --git a/litellm/llms/mongodb/common_utils.py b/litellm/llms/mongodb/common_utils.py index 12391b80959..4aafaf86a5e 100644 --- a/litellm/llms/mongodb/common_utils.py +++ b/litellm/llms/mongodb/common_utils.py @@ -9,6 +9,8 @@ TLS handshake and topology discovery: measured at ~890ms against Atlas versus """ import asyncio +import weakref +from asyncio import AbstractEventLoop from dataclasses import dataclass from typing import TYPE_CHECKING, Final @@ -53,7 +55,12 @@ class MongoClientKey: _sync_clients: dict[MongoClientKey, "MongoClient"] = {} # mutable-ok: process-level connection cache, see module docstring -_async_clients: dict[tuple[MongoClientKey, int], "AsyncMongoClient"] = {} # mutable-ok: same cache, keyed per event loop +# The value carries a weak reference to the loop the client was built on: CPython recycles +# id() aggressively (measured: 200 of 200 fresh loops landed on an id already in this cache), +# so the id alone would hand a new loop a client bound to a closed one. +_async_clients: dict[ # mutable-ok: same cache, keyed per event loop + tuple[MongoClientKey, int], tuple["weakref.ref[AbstractEventLoop]", "AsyncMongoClient"] +] = {} def import_sync_mongo_client() -> "type[MongoClient]": @@ -93,13 +100,14 @@ def get_sync_client(key: MongoClientKey) -> "MongoClient": def get_async_client(key: MongoClientKey) -> "AsyncMongoClient": """Async clients bind to the loop that created them, so the cache is keyed per loop.""" - loop_key: Final = (key, id(asyncio.get_running_loop())) + loop: Final = asyncio.get_running_loop() + loop_key: Final = (key, id(loop)) cached: Final = _async_clients.get(loop_key) - if cached is not None: - return cached + if cached is not None and cached[0]() is loop: + return cached[1] client: Final = import_async_mongo_client()(key.connection_string, **_client_kwargs(key)) - if len(_async_clients) < _MAX_CACHED_CLIENTS: - _async_clients[loop_key] = client + if len(_async_clients) < _MAX_CACHED_CLIENTS or loop_key in _async_clients: + _async_clients[loop_key] = (weakref.ref(loop), client) return client diff --git a/tests/test_litellm/llms/mongodb/vector_stores/test_mongodb_transformation.py b/tests/test_litellm/llms/mongodb/vector_stores/test_mongodb_transformation.py index 15e1b1efab5..9e2bccc3f26 100644 --- a/tests/test_litellm/llms/mongodb/vector_stores/test_mongodb_transformation.py +++ b/tests/test_litellm/llms/mongodb/vector_stores/test_mongodb_transformation.py @@ -1,4 +1,7 @@ +import asyncio +import gc import sys +import weakref from types import SimpleNamespace from unittest.mock import MagicMock, patch @@ -541,6 +544,46 @@ class TestClientCache: assert first is second + def test_a_new_loop_never_inherits_a_closed_loop_client(self): + """CPython recycles id() so aggressively that a fresh event loop almost always lands on + the id of one already collected: measured at 37 of 40 rounds.

Rather than suppress them: - the $vectorSearch and $project stages are MappingProxyType and the query vector a tuple, verified against live Atlas to encode identically. The outer pipeline stays a list because pymongo's common.validate_list raises "pipeline must be a list, not ", which a unit test now pins. - the client caches are Final[dict[...]] and _client_kwargs returns a MappingProxyType. - _field_value recurses over the dotted path instead of rebinding a local. - _client_key declared Final locals in one branch and reassigned them in the others, so it is split into an early-returning _timeout_ms. - the injected callables carry explicit Final[Callable[...]] annotations, which stops pyright resolving self.embedding_fn against litellm.embedding's overloads. - get_sync_client and get_async_client take an optional client_class, so the cache tests inject a recording double instead of patching the importer, and can assert the connection string and timeouts the client was built with. SensitiveDataMasker is public SDK surface, so extra_sensitive_patterns moves to the end of the signature: in slot two it silently reinterpreted an existing caller's positional override set as extra sensitive patterns. --- .../sensitive_data_masker.py | 14 +-- litellm/llms/mongodb/common_utils.py | 53 +++++---- .../mongodb/vector_stores/transformation.py | 109 ++++++++++------- .../management_endpoints.py | 2 +- .../test_sensitive_data_masker.py | 12 ++ .../test_mongodb_transformation.py | 112 ++++++++++++------ 6 files changed, 192 insertions(+), 110 deletions(-) diff --git a/litellm/litellm_core_utils/sensitive_data_masker.py b/litellm/litellm_core_utils/sensitive_data_masker.py index 3b0806ab069..fcce63e016b 100644 --- a/litellm/litellm_core_utils/sensitive_data_masker.py +++ b/litellm/litellm_core_utils/sensitive_data_masker.py @@ -1,13 +1,13 @@ from collections.abc import Mapping +from collections.abc import Set as AbstractSet from typing import Any, Final from pydantic import BaseModel from litellm.constants import DEFAULT_MAX_RECURSE_DEPTH_SENSITIVE_DATA_MASKER - _DEFAULT_SENSITIVE_PATTERNS: Final = frozenset( - { + ( "password", "secret", "key", @@ -23,20 +23,20 @@ _DEFAULT_SENSITIVE_PATTERNS: Final = frozenset( "certificate", "fingerprint", "tenancy", - } + ) ) class SensitiveDataMasker: def __init__( self, - sensitive_patterns: set[str] | None = None, - extra_sensitive_patterns: set[str] | None = None, - non_sensitive_overrides: set[str] | None = None, + sensitive_patterns: AbstractSet[str] | None = None, + non_sensitive_overrides: AbstractSet[str] | None = None, visible_prefix: int = 4, visible_suffix: int = 4, mask_char: str = "*", mask_short_values: bool = True, + extra_sensitive_patterns: AbstractSet[str] | None = None, ): self.sensitive_patterns = (sensitive_patterns or _DEFAULT_SENSITIVE_PATTERNS) | ( extra_sensitive_patterns or frozenset() @@ -44,7 +44,7 @@ class SensitiveDataMasker: # If any key segment matches one of these, the key is not considered sensitive # even if it also matches a sensitive pattern.

The real floor is 4.9, the release AsyncMongoClient landed in, and 4.8 has no AsyncMongoClient at all. Verified against live Atlas on 4.9: sync and async search, list_search_indexes, same top hit and score as 4.17. Resolution is unchanged, pymongo 4.17.0 either way, so this only widens what an existing environment is allowed to bring. --- pyproject.toml | 9 +++------ uv.lock | 4 ++-- 2 files changed, 5 insertions(+), 8 deletions(-) diff --git a/pyproject.toml b/pyproject.toml index c2f0dc6ced7..e3e103e6d49 100644 --- a/pyproject.toml +++ b/pyproject.toml @@ -112,12 +112,9 @@ utils = [ ] caching = ["diskcache>=5.6.3,<6.0"] mcp = ["mcp>=1.28.1,<2.0"] -# Driver for the MongoDB Atlas vector store.

The guidance did not: a refused connection told the operator to check their project's IP access list and whether the cluster was paused, neither of which exists outside Atlas, and the index errors claimed an "Atlas Vector Search index" they do not have. Every message now names a remedy for both, keeping the Atlas-specific hint labelled as such. Also diagnoses unescaped credentials, which self-managed deployments hit more often because the password is usually generated. pymongo reports those three different ways and none of them mentions the password: '@', ':' and '%' raise an RFC 3986 complaint, '/' is read as the database separator and surfaces as Bad database name, and an unescaped ':' looks like a bad port and comes back as a plain ValueError. All three now point at the credentials. The ValueError branch's comment claimed it fired on an unescaped '/', which pymongo actually reports as InvalidURI; corrected to the port parse it really catches.

-0700 Subject: [PATCH 40/66] refactor(vector_stores): route MongoDB query embeddings through the shared executor The base vector store interface grew an embedding_executor argument, and litellm.vector_stores.search now always passes one. MongoDB still carried its own embedding_fn/aembedding_fn constructor seam, so every search through the public entry point failed with an unexpected keyword argument. Drop the local seam in favour of the shared executor: one path instead of two, and the unit tests now drive the same seam production uses. --- .../mongodb/vector_stores/transformation.py | 37 ++++----- .../test_mongodb_transformation.py | 78 ++++++++++++++----- 2 files changed, 76 insertions(+), 39 deletions(-) diff --git a/litellm/llms/mongodb/vector_stores/transformation.py b/litellm/llms/mongodb/vector_stores/transformation.py index 571061d39a2..2e69e35edcf 100644 --- a/litellm/llms/mongodb/vector_stores/transformation.py +++ b/litellm/llms/mongodb/vector_stores/transformation.py @@ -11,15 +11,18 @@ where the id names the index; the database and collection it covers come from litellm_params.

It is a 503 now, with the message still naming the misconfigurations that also close a connection. The client cache skipped insertion once it held 32 entries, so any store added after that rebuilt its client on every search, paying an SRV lookup, a TLS handshake and topology discovery each time. It evicts the least recently used entry instead, which only drops the cache's own reference. Also trims the explanatory comments to the one-line form the repo asks for. --- litellm/llms/mongodb/common_utils.py | 89 ++++++++++--------- .../mongodb/vector_stores/transformation.py | 32 ++----- .../test_mongodb_transformation.py | 87 +++++++++++++++--- 3 files changed, 133 insertions(+), 75 deletions(-) diff --git a/litellm/llms/mongodb/common_utils.py b/litellm/llms/mongodb/common_utils.py index 4e37e21948b..27a2a96bd1f 100644 --- a/litellm/llms/mongodb/common_utils.py +++ b/litellm/llms/mongodb/common_utils.py @@ -1,22 +1,16 @@ -"""Shared helpers for MongoDB integrations. - -pymongo ships in the optional ``mongodb`` extra, so every import of it is -deferred to call time and raises an actionable error when it is absent. - -Clients are cached per connection because building one costs an SRV lookup, a -TLS handshake and topology discovery: measured at ~890ms against a remote deployment versus -~80ms on a warm client, so a client per search would dominate query latency. -""" +"""Shared helpers for the MongoDB integrations. pymongo lives in the optional ``mongodb`` extra, +so every import of it is deferred to call time.""" import asyncio import weakref from asyncio import AbstractEventLoop +from collections import OrderedDict from collections.abc import Callable, Mapping from dataclasses import dataclass from types import MappingProxyType -from typing import TYPE_CHECKING, Final, TypeAlias +from typing import TYPE_CHECKING, Final, TypeAlias, TypeVar -from litellm.exceptions import BadRequestError, Timeout +from litellm.exceptions import BadRequestError, ServiceUnavailableError, Timeout if TYPE_CHECKING: from pymongo import AsyncMongoClient, MongoClient @@ -30,8 +24,7 @@ MONGODB_PROVIDER: Final = "mongodb" def config_error(message: str) -> BadRequestError: - """Misconfiguration is the caller's to fix, so it maps to 400 rather than the 500 - a bare ValueError would become once litellm.exception_type wraps it.""" + """400 rather than the 500 a bare ValueError becomes once litellm.exception_type wraps it.""" return BadRequestError(message=message, model=None, llm_provider=MONGODB_PROVIDER) @@ -39,6 +32,11 @@ def timeout_error(message: str) -> Timeout: return Timeout(message=message, model=None, llm_provider=MONGODB_PROVIDER) +def unavailable_error(message: str) -> ServiceUnavailableError: + """litellm only retries 408, 409, 429 and 5xx, so a 400 here would make a failover permanent.""" + return ServiceUnavailableError(message=message, model=None, llm_provider=MONGODB_PROVIDER) + + DEFAULT_CONNECT_TIMEOUT_MS: Final = 10_000 DEFAULT_SOCKET_TIMEOUT_MS: Final = 30_000 DEFAULT_SERVER_SELECTION_TIMEOUT_MS: Final = 10_000 @@ -59,12 +57,26 @@ class MongoClientKey: SyncClientFactory: TypeAlias = Callable[..., "MongoClient"] AsyncClientFactory: TypeAlias = Callable[..., "AsyncMongoClient"] +_K = TypeVar("_K") +_V = TypeVar("_V") + _AsyncClientCacheKey: TypeAlias = tuple[MongoClientKey, int] # CPython recycles id() aggressively, so the id alone would hand a new loop a closed loop's client _AsyncClientEntry: TypeAlias = tuple["weakref.ref[AbstractEventLoop]", "AsyncMongoClient"] -_sync_clients: Final[dict[MongoClientKey, "MongoClient"]] = {} # mutable-ok: process-level client cache -_async_clients: Final[dict[_AsyncClientCacheKey, _AsyncClientEntry]] = {} # mutable-ok: same cache, per loop +_SyncClientCache: TypeAlias = "OrderedDict[MongoClientKey, MongoClient]" +_AsyncClientCache: TypeAlias = "OrderedDict[_AsyncClientCacheKey, _AsyncClientEntry]" + +_sync_clients: Final[_SyncClientCache] = OrderedDict() # mutable-ok: process-level client cache +_async_clients: Final[_AsyncClientCache] = OrderedDict() # mutable-ok: same cache, per loop + + +def _store_bounded(cache: "OrderedDict[_K, _V]", cache_key: "_K", value: "_V") -> None: + """Eviction only drops this cache's reference;

Both knobs are seeded on enable and cleared on disable, so an off router sends none of the three keys, which is what the backend requires next to session pinning and a custom tier set. The toggle locks out with an explanation when "How often to classify" is set to once-per-session or new-user-message, since both replay a held routing decision instead of classifying and a stall would never reach the classifier. The keys join the custom-tier restriction registry, which both strips them from a custom-tier save and marks the section restricted.

Names come from the DB rows first and fall back to config-declared MCP servers and agents (including legacy agent ids), resolved with one query per table across all groups in a list call. The existing *_ids columns are unchanged The UI renders the name with the id in a tooltip, links teams and keys to their detail pages, and shows the raw id only when nothing resolves ---

A RetryPolicy field can no longer go silently dead the way InternalServerErrorRetries did, and subclasses such as ContentPolicyViolationError or MidStreamFallbackError pick up their parent's field when they have none of their own. Add a DefaultRetries catch-all so errors without a dedicated field (BadGatewayError, APIConnectionError, NotFoundError, ...) can be governed by the policy too. Specific fields still win over DefaultRetries. Wiring the previously dead InternalServerErrorRetries changes one test expectation: a policy of 2 now overrides a per-deployment num_retries of 5, so the amplification test sees 3 upstream requests instead of 6. Expose DefaultRetries as "All other errors" in the Admin UI retry settings tab and ratchet the lint budgets down by the violations this branch fixed. --- basedpyright-code-budget.json | 8 +- litellm/router_utils/get_retry_from_policy.py | 83 +++++---- litellm/types/router.py | 1 + ruff-strict-budget.json | 2 +- .../test_get_retry_from_policy.py | 169 +++++++++++------- tests/test_litellm/test_router.py | 31 ++-- .../test_router_per_deployment_num_retries.py | 7 +- type-discipline-budget.json | 4 +- .../components/ModelRetrySettingsTab.tsx | 1 + ui/litellm-dashboard/src/lib/http/schema.d.ts | 2 + 10 files changed, 179 insertions(+), 129 deletions(-) diff --git a/basedpyright-code-budget.json b/basedpyright-code-budget.json index 9b59480a0dc..669107bb5b1 100644 --- a/basedpyright-code-budget.json +++ b/basedpyright-code-budget.json @@ -57,7 +57,7 @@ "limit": 5601 }, "reportMissingTypeArgument": { -

A keyword_tier_rule forces its tier and returns before any classification runs, so stall escalation never reached that path even though keyword escalation did. That left the one path that can pin a weak model to a whole conversation as the one path a stall could not lift. Stall detection now resolves before the override branch and both paths bump. The dashboard switch disabled itself whenever session pinning or user-turn classification was on, including for a router that already had stall escalation enabled. The conflicting keys stayed set, the backend rejected the save, and the disabled switch was the only way to clear them. It now disables only the off-to-on direction. --- .../complexity_router/complexity_router.py | 22 ++++++++------- .../router_strategy/test_complexity_router.py | 27 +++++++++++++++++++ .../add_model/StallEscalationConfig.test.tsx | 7 +++++ .../add_model/StallEscalationConfig.tsx | 5 +++- 4 files changed, 50 insertions(+), 11 deletions(-) diff --git a/litellm/router_strategy/complexity_router/complexity_router.py b/litellm/router_strategy/complexity_router/complexity_router.py index 01b4665a7d9..5815f7577b9 100644 --- a/litellm/router_strategy/complexity_router/complexity_router.py +++ b/litellm/router_strategy/complexity_router/complexity_router.py @@ -3053,6 +3053,14 @@ class ComplexityRouter(CustomLogger): newest_ask: Final = _newest_turn_ask(resolved_messages, self._reminder_markers) escalation_keyword: Final = self._matched_escalation_keyword(newest_ask) if newest_ask is not None else None + # Resolved here rather than beside the classifier because the keyword-override path below + # returns before any classification runs, and a forced tier gets stuck for the same reason + # a classified one does. + stalled: Final = self.config.stall_escalation_enabled and detect_stalled_task( + resolved_messages, + window=self.config.stall_escalation_window, + repeat_threshold=self.config.stall_escalation_repeat_threshold, + ) plan_mode_sentinel: Final = self._matched_plan_mode_signal(request_kwargs, resolved_messages) plan_floor: Final = self._resolve_plan_mode_floor() if plan_mode_sentinel is not None else None @@ -3082,10 +3090,11 @@ class ComplexityRouter(CustomLogger): override: Final = await self._resolve_keyword_tier_override(user_message, request_kwargs) if override is not None: -
