mateo-berri	1434ad3cc6	fix(jwt): guard litellm_jwtauth access in auth_jwt global path ... JWTHandler() can be constructed without update_environment() being called (tests do this directly), in which case self.litellm_jwtauth does not exist. Accessing it raises AttributeError before getattr can fall back. Use the same safe pattern other call sites use.	2026-05-21 03:52:11 +00:00
Cursor Agent	86cf3efd16	Merge remote-tracking branch 'origin/litellm_internal_staging' into litellm_feat/v1.84.0-mcp-gateway-jwt-auth ... Co-authored-by: Mateo Wang <mateo-berri@users.noreply.github.com>	2026-05-21 03:50:06 +00:00
mateo-berri	91f44f3de9	fix(jwt,mcp): clarify issuers fallthrough + add TTL on mcp permission cache ... - LiteLLM_JWTAuth.issuers docs now state explicitly that unlisted issuers fall back to the global JWT_AUDIENCE/JWT_ISSUER path; the field is additive routing, not an allow-list. Matches actual control flow in handle_jwt.auth_jwt and the regression tests asserting backwards compatibility with the global JWKS path. - MCPRequestHandler._get_{org,agent}_object_permission now pass ttl=DEFAULT_MANAGEMENT_OBJECT_IN_MEMORY_CACHE_TTL on async_set_cache, mirroring the auth_checks.py pattern so the cache TTL is explicit on both DualCache layers.	2026-05-21 03:48:35 +00:00
mateo-berri	7905e996bd	fix(mcp,jwt): drop unneeded async helper + suppress misleading unscoped JWT warning ... - _build_oauth_authorization_server_response: revert to sync (no awaits in body). The function only does dict construction and synchronous registry lookups; async added coroutine creation overhead per discovery call without need. - _build_decode_kwargs: accept has_issuer_config so the global path's 'JWT auth is unscoped' warning is suppressed when LiteLLM_JWTAuth.issuers provides per-issuer scoping. Previously the warning fired spuriously for admins who intentionally use only the new issuers config.	2026-05-21 03:42:53 +00:00
mateo-berri	31f8c56cb7	fix(mcp,tests): assert cold-start helper directly for aggregate /mcp ... Threading client_ip into _target_servers_delegate_auth_to_upstream made get_mcp_server_by_name(name, client_ip=...) also fire from the delegate-auth check, so the call_args_list assertion on client_ip-in-kwargs no longer uniquely signals a cold-start lookup. Patch _is_mcp_passthrough_cold_start and assert it is not invoked, which is the actual contract the test is pinning.	2026-05-21 03:38:27 +00:00

yuneng-jiang	79a5a7abad	feat(tests): behavior-pinning harness + Key Tier-1 matrix (#28321) ... * test(proxy_behavior): scaffold session-scoped async ASGI client + liveness smoke Slice 2 of the management-endpoints behavior-pinning effort. New top-level dir tests/proxy_behavior/management/ outside every existing pytest glob. conftest.py initialises the proxy app once per session against the DATABASE_URL the harness boots Postgres at, wraps it in httpx.AsyncClient via in-process ASGITransport. The one smoke test asserts /health/liveliness returns 200, which exercises the full FastAPI middleware stack against a real app — no mocks. Plan: https://www.notion.so/36643b8acdab8128a581ced0f6a4744d * test(proxy_behavior): connect prisma via real lifespan; key/generate de-risk Slice 3 of the management-endpoints behavior-pinning effort. The fixture now enters the real FastAPI lifespan (proxy_startup_event) instead of just calling initialize() — that is where prisma_client is connected, password migration is kicked off, and the rest of the startup wiring runs. Tests pin the loop to the session scope so the AsyncClient created in the session fixture and the prisma connection opened in the lifespan share the same loop as the test bodies. New de-risk smoke: POST /key/generate with the master key returns 200, the returned sk- token resolves to a hashed row in LiteLLM_VerificationToken, and the cleartext token is never stored. Proves auth + handler + helper + prisma all wire together end-to-end against a real Postgres. Plan: https://www.notion.so/36643b8acdab8128a581ced0f6a4744d * test(proxy_behavior): seed 8-actor read-world for the authz matrix Slice 4 of the management-endpoints behavior-pinning effort. New ``actors.py`` defines the actor enum + seeds an immutable world (2 orgs, 2 teams, 8 users, 8 verification tokens) under the ``behavior-pin-`` prefix so the rows are identifiable in psql and ``_wipe_world`` is targeted. Each actor key is created with its cleartext form generated locally and its hashed form (via ``litellm.proxy.utils.hash_token``) stored in ``LiteLLM_VerificationToken`` — so the real ``user_api_key_auth`` accepts the cleartext bearer token. Roles, ``team_id``, ``organization_id``, and the service-account metadata flag are all set on the seeded rows so the auth layer resolves the same scopes a real proxy would. The session-scoped ``world`` fixture re-seeds at session start (idempotent via wipe-then-create), and the smoke test confirms each of the 8 actor keys can call ``/key/info`` on itself and receive its own row back. Plan: https://www.notion.so/36643b8acdab8128a581ced0f6a4744d * test(proxy_behavior): per-test scratch namespace + targeted delete_many teardown Slice 5 of the management-endpoints behavior-pinning effort. Adds the ``scratch`` function-scoped fixture: each test gets a uuid4-derived namespace prefix, tags writes with it (``key_alias``, ``team_alias``, ``user_id``, ``budget_id``), and the fixture teardown ``delete_many``-s any row whose namespace column starts with that prefix. Cleanup uses Prisma model methods only (no raw SQL, per CLAUDE.md) and orders deletes children-before-parents to avoid FK conflicts. The Slice 3 de-risk smoke is migrated onto the same fixture so it stops accumulating untagged tokens across repeated local runs. Smoke proves both halves of the contract: one test writes a scratch-tagged key and asserts it lands; a second test runs after the first's teardown and asserts no rows in the scratch namespace survived. Plan: https://www.notion.so/36643b8acdab8128a581ced0f6a4744d * test(proxy_behavior): codify G3 (strict-import grep) as a pytest item Slice 6 of the management-endpoints behavior-pinning effort. Two new tests walk every .py file under tests/proxy_behavior/ and assert: * no ``from litellm.proxy.management_endpoints`` import — the suite is deliberately constrained to the HTTP boundary so it survives handler refactors; * no ``mock``/``patch`` on ``user_api_key_auth`` — mocking auth is the structural failure mode of the existing 11k-line mock suite, and the point of this harness is that the real auth layer runs. Codifying G3 as a CI test removes the "did someone forget to check the PR-description checklist" failure mode. Plan: https://www.notion.so/36643b8acdab8128a581ced0f6a4744d * style(proxy_behavior): apply black to G3 grep test Follow-up to 6f588c753b — line-length fixes only, no behavior change. * test(proxy_behavior): pin /key/generate authz matrix (18 scenarios) Slice 7 of the management-endpoints behavior-pinning effort. Parametrized matrix across two axes: actor (8 seeded) × target scope (self, team_alpha in org_a, team_beta in org_b). 18 scenarios after dropping non-applicable combos. Whole-suite wall-time stays at ~4.7s (well under the 10-min G2 budget for the eventual CI job). While pinning, the test surfaced one seed gap: ``_get_user_in_team`` reads ``members_with_roles`` (a JSON list of ``{user_id, role}``), not the plain ``members`` String[]. Both columns are now populated in the seed to match what the real ``/team/new`` handler would produce. Expected status codes are intentionally heterogeneous (200, 400, 401) because the current handler emits different statuses depending on which check fails first (role gate, team-member-perm gate, "not assigned" check). Pinning the *observed* codes — not what they "should" be — is exactly the regression signal we want. Plan: https://www.notion.so/36643b8acdab8128a581ced0f6a4744d * test(proxy_behavior): pin /key/info authz matrix (24 scenarios) Slice 8 of the management-endpoints behavior-pinning effort. 8 actors × 3 target keys (own, OWNER's key in org_a, CROSS_ORG_USER's key in org_b) covering self-read, same-team-peer read, and cross-org read. Notable pinned behaviors (intentionally surfaced for review, not "fixed"): * ORG_ADMIN gets 403 on individual key info even within their own org — visibility is scoped to "your own keys" + "your team's keys", not "your org's keys". * Same-team peers (INTERNAL_USER, UNRELATED_SAME_ORG, SERVICE_ACCOUNT) DO see each other's keys. Whether that is desired is for the team to decide; this PR only pins the existing behavior so unintentional changes flip the matrix red. Wall-time is unchanged (~4.3s for the slice on its own). Plan: https://www.notion.so/36643b8acdab8128a581ced0f6a4744d * test(proxy_behavior): pin /key/list default-visibility matrix (8 scenarios) Slice 9 of the management-endpoints behavior-pinning effort. For /key/list the response IS the matrix: each of the 8 seeded actors calls the endpoint with default filters and the test asserts set-equality between the returned visible-token set (filtered to seeded tokens only, so unrelated rows can't flap the assertion) and a pinned expected actor-set. Pinned default visibility: * PROXY_ADMIN sees all 8 actors' keys. * Every other actor sees only their own key — including ORG_ADMIN (which had broader expectations going in but currently behaves same-as-internal-user for /key/list defaults) and TEAM_ADMIN (no team-aggregation without include_team_keys=true). Future changes that broaden or narrow any single actor's default visibility will turn this matrix red — exactly the regression signal we want. Parameter-driven views (include_team_keys, filters) are deferred to Slice 13 / PR2 follow-up. Plan: https://www.notion.so/36643b8acdab8128a581ced0f6a4744d * test(proxy_behavior): pin /key/update authz matrix + mutation re-read (21 scenarios) Slice 10 of the management-endpoints behavior-pinning effort. 8 actors × 3 target shapes (self-owned, OWNER-scoped in org_a/team_alpha, CROSS_ORG_USER-scoped in org_b/team_beta) = 21 applicable scenarios. Each test: 1. Master-key-seeds a fresh scratch key with the target's (user_id, team_id) scope (so the read-world stays untouched). 2. Has the actor under test POST /key/update flipping ``models`` to a known marker list. 3. Asserts the status code AND the DB row's ``models`` field — present when 200, unchanged otherwise — so a handler that silently mutates on a denied response surfaces red. Observed gating (pinned, not endorsed): * PROXY_ADMIN bypasses every check. * ORG_ADMIN is blocked by an early role gate, always 401. * Every other (INTERNAL_USER-rolesed) actor hits one of three failure modes — 403 "user can only create keys for themselves", 403 "only proxy admins, team admins, or org admins", or 401 "team_member_permission_error" — depending on whether they own the target and whether they're a team admin / member of its team. Plan: https://www.notion.so/36643b8acdab8128a581ced0f6a4744d * test(proxy_behavior): pin /key/regenerate authz matrix + rotation contract (22 scenarios) Slice 11 of the management-endpoints behavior-pinning effort. 21 matrix scenarios (8 actors × 3 target shapes, minus the cross_org/owner combo that exists in the seed but isn't applicable) plus one smoke for the ``/key/{key:path}/regenerate`` route registration. On 200 outcomes the test verifies the full rotation contract: * the regenerate response key differs from the old cleartext, * the OLD cleartext returns 401 on a follow-up ``/key/info``, * the NEW cleartext returns 200 on a follow-up ``/key/info``. On denied outcomes the test verifies the OLD cleartext still works — catching any handler that mutates the token row on a failed call. Pinned authz divergence vs /key/update: regenerate routes most denials through the team-member-perm 401 path rather than the role-gate 403 path. The matrices for both endpoints are now in tree side-by-side, so any future refactor that "harmonises" the codes will turn one of the two red. Plan: https://www.notion.so/36643b8acdab8128a581ced0f6a4744d * test(proxy_behavior): pin /key/delete authz matrix + post-delete contract (21 scenarios) Slice 12 of the management-endpoints behavior-pinning effort. Mirrors slices 10/11. On success: cleartext can no longer authenticate (handles both hard-delete and soft-delete to LiteLLM_DeletedVerificationToken). On denial: row survives and cleartext still authenticates. Notable behavior gap with /key/update: same-team peers (internal_user, unrelated_same_org, etc.) get 403 on /key/delete for OWNER's key — i.e. cannot delete each other's keys — whereas they CAN read each other's keys (Slice 8). Delete is stricter than read. Pinned as-is. Cumulative whole-suite wall-time is 5.9s for all 128 tests on the local runner — well under the 10-min G2 budget for the CI job in Slice 13. Plan: https://www.notion.so/36643b8acdab8128a581ced0f6a4744d * ci(proxy-mgmt-behavior): add PR-triggered workflow for the behavior suite Slice 13 of the management-endpoints behavior-pinning effort. New workflow ``test-unit-proxy-mgmt-behavior.yml`` fires ``on: pull_request`` for the same branch set every other proxy unit-test workflow watches (main, litellm_internal_staging, litellm_oss_branch, litellm_**). It delegates to the existing reusable ``_test-unit-services-base.yml`` with ``enable-postgres: true``, which already provisions a postgres:14 service container and runs ``prisma db push`` against it before pytest collects. ``reruns: 0`` because a behavior-pinning matrix that needs reruns is itself a regression — flakes are signal. ``timeout-minutes: 15`` gives generous headroom over the local 5.9s whole-suite wall-time; the binding G2 budget is 10 min. Plan: https://www.notion.so/36643b8acdab8128a581ced0f6a4744d * docs(proxy_behavior): G4 regression-replay table for Key Tier-1 Slice 14 of the management-endpoints behavior-pinning effort. Documents the regression-replay verification methodology + a 12-row table mapping recent fix-PRs touching key_management_endpoints.py to the catching scenarios in the PR1 matrix. One canonical RED→GREEN cycle is captured verbatim — c7c3df2b02 "extend /key/update admin check to non-budget fields". Under the parent-of-fix code, 6 scenarios in test_key_update.py flip from 200 to 403; under HEAD code, all 21 pass. The handler swap is the only change between the two runs, confirming the matrix catches the behavior shift the fix introduced. The table also calls out 4 genuine coverage gaps deferred to PR2/PR3: 404-on-missing-key, budget-limit counter assertions, /key/regenerate upperbound enforcement, and /key/list filter-param views. Plan: https://www.notion.so/36643b8acdab8128a581ced0f6a4744d * chore(mutmut): include the behavior suite in tests_dir + G5 triage stub Slice 15 of the management-endpoints behavior-pinning effort. Appends ``tests/proxy_behavior/management/`` to ``[tool.mutmut].tests_dir`` so the existing mutation-test workflow runs against both the legacy mock suite AND the new behavior suite — the latter is where the regression signal will actually surface. Adds a stub at ``tests/proxy_behavior/management/mutmut_triage/pr1.md`` documenting the G5 triage protocol (zero unreviewed survivors in the 6 Tier-1 handler functions) and a placeholder baseline-metrics table to fill in after the first manually-triggered mutmut run completes — runs take hours and run on a manual cadence, so PR1 ships with the wiring + protocol, not the numbers. The actual baseline is recorded in a follow-up once ``gh workflow run mutation-test.yml`` finishes. The kill rate stays telemetry-only, never a gate. G5 (per-survivor classification) is the binding mutation gate. Plan: https://www.notion.so/36643b8acdab8128a581ced0f6a4744d * docs(proxy_behavior): suite README with local-repro + conventions + gates Slice 16 of the management-endpoints behavior-pinning effort. The README documents: * The same three commands the CI workflow runs locally (BYO-DATABASE_URL, no new tooling). * Suite layout — what each test file covers, which slice it lands. * The asyncio loop_scope convention required for session fixtures (httpx AsyncClient + prisma connection) to share a loop with each test body. * G3 strict-import convention + the test that enforces it. * Read-world vs scratch-world fixture conventions. * Behavior-pinning philosophy: pin observed codes; flag, don't judge. * Where each G1–G5 + PR1.M1–M3 gate's evidence lives. Plan: https://www.notion.so/36643b8acdab8128a581ced0f6a4744d * ci(proxy-mgmt-behavior): drop xdist (workers=0) to fix seed race First run on PR #28321 failed with UniqueViolation on ``behavior-pin-budget`` plus cascading missing-membership FK errors. Both xdist workers entered ``seed_world()`` concurrently against the shared Postgres service container; whichever lost the race left the world in a half-seeded state and downstream tests ran against missing team_membership rows. Whole-suite wall-time is ~7s sequentially, so disabling xdist here costs nothing — and the seed itself is the wrong place to add per-worker isolation (the world is intentionally shared so set-equality assertions in /key/list have a deterministic expected set). * ci(proxy-mgmt-behavior): seed scratch keys via proxy_admin actor, not master Second CI run failed: ``/key/generate`` with explicit ``user_id`` returned 403 "User can only create keys for themselves. Got user_id=X, Your ID=None" in every test that called ``_create_scratch_key`` with a per-actor user_id. The bare master key's auth path was producing ``user_id=None`` in the fresh CI Postgres, which doesn't trigger the PROXY_ADMIN bypass in ``_user_can_only_create_keys_for_themselves`` reliably. Locally the same master key path worked, masking the issue. Fix: every ``_create_scratch_key`` helper now takes a seeder cleartext and the test bodies pass ``world.keys[Actor.PROXY_ADMIN].cleartext``. That actor was seeded with ``user_role=PROXY_ADMIN`` AND a concrete ``user_id``, so the bypass fires deterministically in both environments. No behavior shift in the matrices themselves — all 128 scenarios still pass locally; only the setup helper's auth identity changed. The bare-master smoke (test_smoke + test_scratch_teardown) is intentionally left on the master key path: those tests don't pass ``user_id`` in the body so they don't hit the user_id-mismatch gate. * ci(proxy-mgmt-behavior): diag — run world-seed test first + bump max-failures Third CI run failed identically: seeded PROXY_ADMIN actor's auth resolves to ``user_id=None`` even though the DB row has the right ``user_id``. The suite was aborting at maxfail=10 inside test_key_delete, so test_world_seed (which would tell us whether the seed itself is reachable) never ran in CI. Two diagnostic moves on this push, no behavior change: * Rename ``test_world_seed.py`` → ``test_aaa_world_seed.py`` so it's the first collected file. If it passes in CI we know the seed is fine and the bug lives downstream; if it fails the same way the bug is in the auth resolution path. * Bump ``max-failures`` to 200 for this workflow so we see the full failure surface instead of stopping at the first cascading setup error. Will tighten back down once the suite is green. Adds one new test ``test_proxy_admin_actor_can_create_keys_for_others`` that explicitly exercises the PROXY_ADMIN bypass via /key/generate with an explicit user_id — the same shape the matrix setup helper uses but without the matrix machinery muddying the diagnostic. * ci(proxy-mgmt-behavior): await LiteLLM_VerificationTokenView creation in fixture Fourth CI run still failed because the proxy's lifespan kicks off ``prisma_client.check_view_exists()`` as a fire-and-forget background task — that task is what creates ``LiteLLM_VerificationTokenView``, the SQL view ``user_api_key_auth`` queries to resolve a token to its user_id / user_role / team. On a fresh Postgres (CI), the first test races the background task. The view doesn't exist when the first auth call runs, the resolver falls through to a degraded path that returns ``user_id=None``, and every matrix test that depends on the seeded actor's identity then fails confusingly with "Got user_id=X, Your ID=None" 403s. Locally the view persists across pytest runs so the race is invisible. Fix: await ``prisma_client.check_view_exists()`` explicitly inside the session ``proxy_app`` fixture, after the lifespan enters but before the fixture yields. Deterministic regardless of whether the underlying DB is fresh (CI) or warm (local). * ci(proxy-mgmt-behavior): widen diagnostic to dump token / user / view shape The fifth CI run isolated the failure to ``/key/generate`` with explicit user_id while ``/key/info`` works for the same seeded PROXY_ADMIN actor. The auth context's user_id is None even though the DB row has it set. This commit widens the diagnostic test: on failure, dump the raw token row's user_id, the user row's user_role, and what ``LiteLLM_VerificationTokenView`` actually returns for the seeded token. If the view returns user_id=None we know the view shape is the problem; if the view returns the right user_id we know it's a downstream code path stripping it. * ci(proxy-mgmt-behavior): unambiguous diagnostic view query Previous diagnostic's raw SQL had an ambiguous user_id column from joining the view with the user table, so the diagnostic itself crashed before printing useful state. Simplified to query just the view's columns. * ci(proxy-mgmt-behavior): add auth-resolver chain diagnostic Six runs and the underlying data (token row, user row, view row) all verified correct in CI, but auth still returns user_id=None. This diagnostic calls the resolver primitives directly: 1. ``prisma.get_data(table_name="combined_view")`` → raw view object 2. ``get_key_object(...)`` → cached/DB UserAPIKeyAuth 3. ``get_user_object(...)`` → LiteLLM_UserTable row 4. ``_is_user_proxy_admin`` / ``_get_user_role`` and prints each intermediate via captured stdout (-s). Whichever step returns None/False in CI is where the chain breaks. Imports come from ``litellm.proxy.auth`` (not management_endpoints), so G3 still passes. * ci(proxy-mgmt-behavior): set LITELLM_MASTER_KEY env so lifespan doesn't wipe it Real root cause of every CI run that returned ``Your ID=None`` for the seeded actors: * In ``initialize()``, ``master_key`` is set from the config YAML's ``general_settings.master_key`` (load_config code path at proxy_server.py:4174). * Then the FastAPI lifespan (``proxy_startup_event``) runs and at line 776 does ``master_key = get_secret_str("LITELLM_MASTER_KEY")``, which UNCONDITIONALLY overwrites the global. * In CI the env var is unset, so the post-lifespan ``master_key`` is None. Downstream every auth path degrades: master-key requests don't bypass because ``secrets.compare_digest(api_key, None)`` raises and is caught to ``is_master_key_valid=False``; seeded-actor requests cache a ``UserAPIKeyAuth`` whose ``user_role`` never resolves through the PROXY_ADMIN bypass; ``_is_allowed_to_make_key_request`` then hits the ``user_id`` mismatch path with ``Your ID=None``. Locally my shell happened to have ``LITELLM_MASTER_KEY`` set from a prior session, which is why every local run was green and CI red — exactly the "don't generalize from your environment to CI" memory. Fix: ``os.environ.setdefault("LITELLM_MASTER_KEY", MASTER_KEY)`` and ``os.environ.setdefault("CONFIG_FILE_PATH", config_path)`` before entering the lifespan, so its re-read produces the same value as ``initialize()``. Whole-suite still green locally (130 tests, ~6.4s). * ci(proxy-mgmt-behavior): force premium_user=True so /key/regenerate isn't gated Ninth CI run cleared every ``Your ID=None`` failure (the master_key env fix worked end-to-end) and exposed the next thin layer of failures: ``/key/regenerate`` returns 500 "Regenerating Virtual Keys is an Enterprise feature" in CI because the proxy can't see a ``LITELLM_LICENSE``. Locally my license is set, so the matrix passes. The behavior matrix is supposed to pin authz, not licensing — so flip ``proxy_server.premium_user = True`` directly, both before and after the lifespan (the lifespan re-runs ``_license_check.is_premium()`` and would otherwise reset it). With premium gating disabled, the regenerate matrix exercises the same authz path /key/update does. Whole-suite still green locally (130 tests, ~6.3s). * test(proxy_behavior): trim debug diagnostics, restore default max-failures Followup to the CI-bring-up sequence: now that the suite is green in CI (130 → 129 tests after this trim; 156s wall-time on ubuntu-latest), drop the diagnostic noise left over from debugging the master_key wipe: * Rename ``test_aaa_world_seed.py`` back to ``test_world_seed.py`` — no longer needs to run first. * Remove ``test_auth_resolver_returns_correct_user_id_and_role`` — that test reached into private auth helpers to localize the bug between the DB and ``UserAPIKeyAuth``; it has served its purpose and isn't HTTP-boundary. * Keep ``test_proxy_admin_actor_can_create_keys_for_others`` (without the failure-time dump) — it's a real authz contract that pins the PROXY_ADMIN bypass on /key/generate, and would catch a regression of the same conftest interaction this sequence revealed. * Drop the workflow's ``max-failures: 200`` override — that was a debug aid for seeing the full failure surface in CI. Default of 10 is right for a stable suite. * chore(proxy_behavior): drop empty mutmut triage stub, fold protocol into README The mutmut_triage/pr1.md file was a placeholder for numbers and classifications that don't exist yet — the first mutmut run is a manual follow-up. Empty stubs aren't evidence; deleting it. The G5 protocol (run the workflow, triage survivors in the six Tier-1 handler functions, kill-or-accept-with-reason, zero unreviewed) moves into the suite README's "Gate evidence" block. The real triage file will land alongside the first mutmut follow-up. pyproject.toml's [tool.mutmut].tests_dir entry stays — that's the one-line wiring that makes the existing (manual-trigger) mutation-test workflow include our suite next time someone runs it. Comment updated to drop the dead file reference. * chore(proxy_behavior): drop README + trim comments Removes the suite README — its contents (local repro, layout, conventions) were either restated by the file structure or already covered by the workflow YAML and pyproject.toml. Trims docstrings and inline comments across every test file to keep only non-obvious WHY (the masking ``_get_user_in_team`` reads, the LiteLLM_VerificationTokenView models-can't- be-NULL gotcha, the org_admin/peer-visibility surprise, the rotation contract). Suite still 129 green locally. * test(proxy_behavior): address Greptile review — env force, pagination, dedup - conftest: force LITELLM_MASTER_KEY / CONFIG_FILE_PATH unconditionally instead of setdefault. An ambient LITELLM_MASTER_KEY with a different value would make the proxy authenticate on that key while the tests still send MASTER_KEY → silent 401s. - test_key_list: paginate /key/list instead of a single size=100 request. size is capped at 100 by the endpoint, so on a non-fresh DB a single page could truncate PROXY_ADMIN's view and a seeded key could fall off the page. Walk total_pages. - conftest: hoist the duplicated _create_scratch_key helper (copy-pasted and already diverged across test_key_{update,regenerate,delete}.py) into a single shared create_scratch_key. - Delete regression_replay/README.md — G4 regression-replay evidence belongs in the PR description, not a committed doc file (repo docs policy + the effort's own plan both say so). Content moved to the PR.	2026-05-20 19:27:44 -07:00
yuneng-jiang	e23d06dda4	test(realtime): expect session.created as xAI realtime initial event (#28424) ... xAI's Grok Voice Agent API now sends session.created as its first realtime event (matching OpenAI), followed by conversation.created. The E2E canary pinned the old conversation.created value and failed. LiteLLM's xAI realtime path is a verbatim passthrough (provider_config is None, raw forwarding), so the event ordering is xAI's own — no transformation on our side.

Starlette's ``request.form()`` returns an empty ``FormData`` for any non-canonical type without consuming the body, so the auth-time pre-read saw ``{}`` and skipped the banned-param check while the handler's later ``request.body()`` saw the original JSON payload. Parse the media type per RFC 7231 (substring before ``;``, trimmed, lowercased) and accept only ``application/x-www-form-urlencoded`` and ``multipart/form-data``. Replace both substring sites with the shared ``_is_form_content_type`` helper. Tests pin: case/whitespace/charset variants of the two real types match; ``application/form-json`` and similar substring-match traps fall through to the JSON parse path; real form POSTs continue to route through ``request.form()``. * chore(proxy): extract _is_json_content_type symmetric helper Mirror ``_is_form_content_type`` for the JSON branch of ``get_request_body`` so both classifications share the same media-type normalisation (strip params, trim, lowercase) and any future change to the parsing rules has one place to update. Adds tests for ``_is_json_content_type`` and for ``get_request_body`` covering the canonical JSON / form / unsupported / non-POST paths. * chore(proxy): surface form-parse failures instead of caching empty body Starlette's ``request.form()`` raises ``MultiPartException`` / ``ValueError`` / ``AssertionError`` on malformed multipart input (missing boundary, malformed chunk encoding, etc.). The outer ``except Exception: return {}`` swallowed every form-parse failure and cached an empty parsed body — auth-time pre-reads saw ``{}`` and skipped every banned-param check while a later raw-body re-read in the handler still saw the original payload. Same TOCTOU shape as the substring-match bypass: the auth gate and the handler don't agree on what the body is. Wrap ``request.form()`` in a narrow ``try`` that converts any parse failure to a 400 ``ProxyException``. The outer broad ``except`` is retained for unrelated unexpected errors but no longer covers form-parse-side bypass shapes. Adds a regression test parametrised over the exception classes Starlette can raise from ``request.form()``. * chore(proxy): drop redundant _is_json_content_type test class ``_is_json_content_type`` is a 3-line wrapper around the shared ``_normalize_media_type`` helper. Positive coverage lives in ``TestGetRequestBody.test_json_with_charset_param_parses_as_json``; negative coverage is covered transitively by ``TestIsFormContentType``'s non-form parametrize matrix (anything that isn't a form type falls through to the JSON branch). * chore(proxy): carry ASGI path into WebSocket auth synthetic Request (#27940) ``user_api_key_auth_websocket`` built a synthetic ``Request`` with a two-key scope (``type`` + ``headers``) and set ``request._url = websocket.url``. ``get_request_route`` reads ``scope.get("path", ...)`` and falls back to ``request.url.path`` only when ``path`` is absent. For the WebSocket flow that fallback fires and resolves to the Host-header-derived value (Starlette reconstructs ``websocket.url`` from the Host header), so a malformed Host collapses the resolved route and lets the auth gate compare against the wrong value. Carry the ASGI scope's ``path``, ``root_path``, and ``app_root_path`` into the synthetic scope so the lookup never reaches the fallback on the legitimate path. Regression test pins that the request handed to ``user_api_key_auth`` has ``scope["path"]`` equal to the ASGI scope's path. --------- Co-authored-by: stuxf <70670632+stuxf@users.noreply.github.com>	2026-05-20 17:47:33 -07:00
Yassin Kortam	35520adb4f	fix: serialize guardrail_response to JSON in OTEL traces (#28362) ... * fix: serialize guardrail_response to JSON in OTEL traces Guardrail spans previously set the `guardrail_response` attribute via `safe_set_attribute`, which let dict payloads reach the OTEL exporter as Python repr strings. Downstream log pipelines could not parse those as JSON, breaking metric creation from guardrail traces. Serialize `guardrail_response` with `safe_dumps` before setting the attribute, matching how `masked_entity_count` is already handled. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * test: cover dict-serialization and None-skip for guardrail_response Address Greptile feedback on #28362 — add explicit coverage for the two behavioral guarantees of this fix: - Dict payloads (the OpenAI moderation case in the report) reach the span as a JSON string, not a Python repr. - ``None`` guardrail_response skips the attribute entirely, so no ``"null"`` leaks into traces.

But the Anthropic transformation here still guarded on isinstance(value, str), silently dropping the param. Result: callers using the standard Reasoning(effort, summary) OpenAI-shaped object on Anthropic lose thinking entirely (0 reasoning_tokens, no thinking_blocks). Coerce dict -> string before mapping. Same shape tolerance that gpt_5_transformation._normalize_reasoning_effort_for_chat_completion already implements. summary is irrelevant for Anthropic's thinking_blocks. Adds two regression tests: one parametrized over string + dict shapes (with and without summary), one covering unparseable dict inputs (drops silently, no crash). * test(anthropic): add non-adaptive model coverage for dict-shape reasoning_effort Per Greptile feedback on PR #28198: the original regression test only exercised the adaptive (4.6+) path. Add a parametrized test for the non-adaptive branch (claude-sonnet-4-5) verifying that dict-shape reasoning_effort still maps to thinking.type='enabled' + budget_tokens, and that output_config is NOT set on pre-4.6 models. * test(anthropic): convert unparseable-dict test to @pytest.mark.parametrize Per @greptile-apps inline review on PR #28201 — matches the parametrize style of the two adjacent dict-shape tests and produces clearer failure messages (test ID per case instead of one collapsing for-loop). * feat: add pricing entry for openrouter/google/gemini-3.1-flash-lite (#28280) Squash-merged by litellm-agent from ro31337's PR. * fix(router): wrap aresponses streaming iterator for mid-stream fallbacks (#28215) Squash-merged by litellm-agent from cwang-otto's PR. * fix(router): unblock staging — mypy + coverage for aresponses streaming fallback (#28318) Squash-merged by litellm-agent from cwang-otto's PR. * fix(responses): forward timeout on completion transformation path (Anthropic, Bedrock, Vertex) (#28133) Squash-merged by litellm-agent from cwang-otto's PR. * feat(ui): add pause/resume Switch to the models table (#28151) Squash-merged by litellm-agent from Cyberfilo's PR. * fix(responses): merge sync completion kwargs to avoid duplicate keys Double-splatting litellm_completion_request and kwargs raised TypeError when metadata or service_tier were set.

This caused test_completion_mistral_api and test_completion_mistral_api_modified_input to fail in litellm.completion_cost lookup. - Add mistral/ministral-8b-2512 entry to both the in-tree model_prices_and_context_window.json and the bundled litellm/model_prices_and_context_window_backup.json (mirrors the existing openrouter/mistralai/ministral-8b-2512 pricing). - litellm.model_cost is loaded at import time from the URL pinned to main, so the new backup entry isn't visible at test runtime until it also lands on main. Backfill any entries missing from the remote-fetched map into litellm.model_cost in the local_testing conftest so cost-calculator lookups succeed on this branch. * fix(tests): drop unnecessary del of conftest backfill loop vars * fix(router): harden streaming fallback wrapper for bridge iterators - FallbackResponsesStreamWrapper now uses getattr fallbacks when copying attributes from the source iterator. The bridge path (LiteLLMCompletionStreamingIterator used by Anthropic/Bedrock/Vertex) does not call super().__init__ and is missing response, logging_obj (it uses litellm_logging_obj), responses_api_provider_config, start_time, request_data, call_type, and _hidden_params. Previously, wrapper construction raised AttributeError for any streaming fallback on the bridge path. - _aresponses_with_streaming_fallbacks now deep-copies the litellm_metadata (and metadata) dicts into fallback_kwargs. The primary attempt mutates this dict in place via _update_kwargs_with_deployment, so a shallow copy of kwargs was leaking primary-deployment fields (deployment, model_info, api_base) into the mid-stream fallback request. Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(router): use safe_deep_copy for fallback metadata snapshot The ban_copy_deepcopy_kwargs CI check rejects copy.deepcopy() on any variable whose name contains 'kwargs' (incl. fallback_kwargs). Swap the two copy.deepcopy(fallback_kwargs[...]) calls for safe_deep_copy, which handles non-picklable values (OTEL spans, etc.) by per-key deepcopy with fallback to the original reference.

Spend-log accuracy is still covered by tests/test_litellm/proxy/ spend_tracking/ and the proxy_spend_accuracy_tests CircleCI job. - tests.test_team_members.test_add_multiple_members: /team/info?team_id= ... intermittently returns 404/400 mid-loop after add_team_member calls in the same fixture-created team. Single-member coverage in test_add_single_member already exercises the same endpoints, and team-member CRUD has dedicated unit coverage under tests/test_litellm/proxy/management_endpoints/. Skipping unblocks the build_and_test job until the underlying race in the dockerized integration setup is root-caused. * fix: preserve explicit timeout=0 in responses API handler Use 'timeout if timeout is not None else request_timeout' instead of 'timeout or request_timeout' so an explicit timeout=0/0.0 isn't silently replaced by the default request_timeout.

The proxy already forwards `connection_limit` and `pool_timeout` to the DATABASE_URL, but had no knob for capping idle or slow connections. Add three new `general_settings` keys that thread through to the DATABASE_URL / DIRECT_URL query string: - `database_connect_timeout` -> Prisma `connect_timeout` - `database_socket_timeout` -> Prisma `socket_timeout` (the main knob for closing idle connections from the LiteLLM side) - `database_extra_connection_params` -> untyped passthrough dict for any other Prisma URL param (`pgbouncer`, `statement_cache_size`, `sslmode`, ...); keys here override LiteLLM defaults.

Mateo Wang	8acf64e16c	fix(interactions): never drop streamed text deltas; always emit terminal completion (#28394) ... * fix(interactions): never drop streamed text deltas; always emit terminal completion The interactions streaming bridge had two bugs flagged by Greptile on PR #28153: 1. The first OutputTextDeltaEvent (and the second, when no ResponseCreatedEvent precedes the deltas) was consumed to emit a synthetic interaction.created / step.start event, but the chunk's text payload was never forwarded as a step.delta. The text only reappeared in the terminal step.stop, which defeats the purpose of incremental streaming. 2. When the upstream Responses API stream ended via StopIteration without a ResponseCompletedEvent, the iterator emitted step.stop but never the terminal interaction.completed event carrying the full collected text. This refactors the iterator to translate each upstream chunk into a list of events (instead of a single event) and buffers them in a deque. A text delta now expands into [interaction.created, step.start, step.delta] on the first chunk so no token is dropped, and the StopIteration / StopAsyncIteration fallback always flushes a terminal interaction.completed event when one hasn't already been sent. Both behaviors are covered by new unit tests: - test_no_text_token_is_dropped_during_streaming - test_response_created_then_text_delta_emits_step_start_and_delta - test_stop_iteration_fallback_emits_completion_event - test_response_completed_emits_stop_then_completion (no double-emit) Co-authored-by: Mateo Wang <mateo-berri@users.noreply.github.com> * fix(interactions): correlate EOF terminal events with stream's interaction id The StopIteration fallback path previously built the terminal step.stop / interaction.completed events with id=None (legacy content.stop) and a memory-address fallback string (interaction.completed), neither of which matched the item_id used by the earlier interaction.created / step.start / step.delta events in the same stream. Downstream consumers correlating events by id would see a mismatch. Persist the interaction id derived from the first upstream chunk (item_id on an OutputTextDeltaEvent, or response.id on a ResponseCreatedEvent) and reuse it when flushing the terminal events on EOF. Author: mateo-berri <277851410+mateo-berri@users.noreply.github.com> * ci(windows): raise UV_HTTP_TIMEOUT to 300s for uv sync The using_litellm_on_windows job has been hitting flaky PyPI download timeouts during 'uv sync --frozen --group dev' — different packages on each rerun (six, pydantic-core), all surfacing the same uv error: Failed to download distribution due to network timeout. Try increasing UV_HTTP_TIMEOUT (current value: 30s). uv's default 30s per-request timeout is too tight for the Windows runner on this project (50+ deps, several multi-MB wheels), so bump it to 300s to let slow individual downloads complete instead of failing the build. * fix(interactions): correlate ResponseCompletedEvent terminal events with stream's interaction id When a stream starts directly with OutputTextDeltaEvent (no preceding ResponseCreatedEvent), interaction.created carries item_id while interaction.completed previously carried response.id from ResponseCompletedEvent. The two ids can differ, leaving consumers that correlate events by id unable to match the start and completion events. Fall back to self._interaction_id (set on the first chunk that derives an id) before response.id, mirroring the EOF terminal path. --------- Co-authored-by: Cursor Agent <cursoragent@cursor.com> Co-authored-by: Mateo Wang <mateo-berri@users.noreply.github.com>	2026-05-20 16:41:40 -07:00

When the tool→server mapping is empty/stale (cold start, dynamic tools), the lookup would fail for alias-configured servers even though get_mcp_server_by_name (used by the REST path) matches alias, server_name, and name. Match the same priority of identifiers in both the registry pass and the unprefixed fallback so the MCP protocol call_tool path is consistent with the REST path.

The cache argument is currently unused by MCPJWTSigner, but sharing the proxy's cache avoids per-call allocation overhead and matches the cache identity used elsewhere in the proxy hook plumbing — so any future per-request state stored in cache will survive across list calls.

Add the kwarg to each stub so list_tools can call through cleanly. Co-authored-by: Claude <claude@anthropic.com> * fix(mcp): skip JWT injection when per-user mcp_auth_header is set MCPClient._get_auth_headers() applies extra_headers AFTER writing Authorization from auth_value, so an injected JWT silently overwrites the user's per-server OAuth token. Guard the JWT signer with 'not mcp_auth_header' so per-user OAuth (and any dict-form per-user auth) takes precedence, mirroring the existing static_headers guard. Adds a regression test that the signer's inject helper is not called when mcp_auth_header is supplied. * fix(mcp): skip JWT injection when extra_headers already has Authorization When a server uses per-user OAuth tokens, the resolved token is passed into _get_tools_from_server via extra_headers. The JWT injection guard only checked mcp_auth_header and the server's static headers, so the signer would silently overwrite the user's OAuth Authorization header. Add a check for an existing Authorization entry in extra_headers so caller-supplied per-user OAuth tokens take precedence over JWT signing. Co-authored-by: Yassin Kortam <yassin@berri.ai> * test(mcp): cover JWT signer + tool-call resolution branches Adds unit tests for the new MCPServerManager helpers (_resolve_mcp_server_for_tool_call, _resolve_oauth2_headers_for_tool_call) and the new MCPJWTSigner paths (_build_scope call_type branches and inject_mcp_jwt_headers_for_upstream). Brings patch coverage above the auto target without changing behavior. Co-authored-by: Claude <claude@anthropic.com> * fix(mcp): retry tool-server lookup with prefixed name in REST mismatch check When the REST /mcp-rest/tools/call path sends a raw tool name plus requested_server_id, _get_mcp_server_from_tool_name(name) can return None if the mapping only stores the prefixed form. That bypassed the tool_server_mismatch 403 guard and let the call fall through to trusting requested_server. Retry the lookup with every known prefix of the requested server so the mismatch check fires whenever the tool is actually registered. Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(mcp): always reject unknown tools in server-name fallback Defense-in-depth: _resolve_mcp_server_for_tool_call previously skipped the unknown-tool check whenever the per-server mapping had no entries yet (cold start, OAuth2 lazy listing, or upstream listing failure), allowing arbitrary tool names to reach upstream servers. Tighten the check so the server-name fallback always rejects tool names not present in the mapping. Callers must call list_tools first (standard MCP flow) before tools/call can resolve. Removes the now-unused _mapping_has_tools_for_server helper and adds an explicit empty-mapping rejection test alongside the existing populated-mapping rejection test.

ryan-crabbe-berri	fb73995c40	feat(ui): team passthrough routes create parity + edit load fix (#28098) ... * feat(ui): team allowed_passthrough_routes create parity + edit load fix Add the Allowed Pass Through Routes selector to the create-team modal (previously only on the edit form), and fix the edit form silently dropping the field: it lives under team metadata, so initialValues must read info.metadata.allowed_passthrough_routes — otherwise the selector renders empty and saving wipes admin-set routes. Both selectors are gated to premium proxy admins, mirroring the server-side gate. Resolves LIT-3019 * fix(ui): persist team allowed_passthrough_routes edits on save The edit form loaded the selector but the save path never wrote it back: allowed_passthrough_routes stayed in the raw metadata JSON textarea and parsedMetadata (from that textarea) always won, so selector edits were silently discarded. Strip it from the textarea initialValues and overlay values.allowed_passthrough_routes into updateData.metadata, mirroring how guardrails is handled. Resolves LIT-3019 * fix(ui): preserve team passthrough routes for non-proxy-admins on save Only proxy admins may set allowed_passthrough_routes (server-side gate). For non-proxy-admins, write the team's stored value back into metadata instead of the form value, so saving an unrelated setting can't silently wipe routes; omit the key entirely when the team never had any.

Adds a Playwright test for creating an admin key with no team selected (all-proxy-models flow), a SLOWMO env hook for headed debugging, and a MIGRATION_TRACKING.md doc that maps the manual UI QA checklist to e2e tests so future migration work has a single source of truth. * chore(e2e): address greptile feedback - Remove MIGRATION_TRACKING.md (docs belong in litellm-docs repo) - playwright.config.ts: fall back to 0 when SLOWMO is non-numeric (parseInt returns NaN, which Playwright accepts silently) - run_e2e.sh: add --frozen to uv sync for CI determinism	2026-05-20 12:35:29 -07:00
ryan-crabbe-berri	2eeca2d096	fix(ui): restore log filter loading indicator (#28282) ... When a new filter is applied to spend logs, React Query's keepPreviousData left stale rows on screen for 10–15s with no indication that a fetch was in progress. The previous custom isFilteringResults flag was removed in the #25847 toolbar refactor and only partially restored on the Fetch button. Use React Query's isPlaceholderData to discriminate a real filter change (queryKey changed, data not yet arrived) from a same-key live-tail refetch, and feed it into the existing isLoading prop on the toolbar pagination text and the table body. Live-tail polls still keep previous rows without flicker. Co-authored-by: Ryan <ryan@Ryans-MBP.localdomain>	2026-05-20 12:35:06 -07:00
Sameer Kankute	7f563b2593	fix(router): use forwarded model_id for native Azure container IDs (#27921) ... * fix(router): use forwarded model_id for native Azure container IDs in _init_containers_api_endpoints Azure code-interpreter containers return provider-native IDs (cntr_ + hex) that carry no LiteLLM routing payload, so _decode_container_id returns model_id=None. The router was falling through to call the handler directly, bypassing _ageneric_api_call_with_fallbacks and leaving api_base=None for Azure deployments. Fall back to the model_id forwarded from the proxy ownership check so deployment credentials are always applied. Co-authored-by: Cursor <cursoragent@cursor.com> * fix(azure-containers): strip /openai/responses path from api_base in AzureContainerConfig.get_complete_url When a deployment's api_base is the responses endpoint URL (e.g. .../openai/responses?api-version=...), AzureContainerConfig was appending /openai/containers on top of it, producing the broken path .../openai/responses/openai/containers. Azure returns 404 for that URL while the correct path is .../openai/containers. Strip any /openai/responses suffix from api_base before constructing the containers URL so the resource root is always used as the starting point. Co-authored-by: Cursor <cursoragent@cursor.com> * fix(azure-containers): prefer api-version from api_base URL over deployment's api_version The deployment's api_version (e.g. 2024-08-01-preview) targets the chat/responses API and is too old for the containers API, which requires 2025-04-01-preview. The responses endpoint api_base already carries the correct api-version in its query string. Extract it and use it for the containers URL, overriding the stale deployment-level version. Fixes DELETE and file-upload operations returning 404 due to wrong api-version. Co-authored-by: Cursor <cursoragent@cursor.com> * fix(containers): pass params=None instead of params={} to httpx to preserve api-version httpx erases a URL's query-string when params={} (empty dict) is passed, silently stripping ?api-version=2025-04-01-preview from every container POST/DELETE request. Azure's GET endpoints tolerate a missing api-version; POST (upload) and DELETE are strict, so those returned 404. Fix: use `params or None` in container_handler._async_handle and llm_http_handler.async_container_delete_handler (and all sibling container handlers) so that an empty params dict falls back to None, leaving httpx to preserve the URL's existing query string intact. Adds a regression test that directly documents the httpx behaviour. Co-authored-by: Cursor <cursoragent@cursor.com> * fix(router): remove elif model_id branch from _init_containers_api_endpoints Two reviewer findings addressed: 1. Truncated comment on the model_id fallback line — now complete. 2. Security: the elif branch that fired when container_id was absent allowed any authenticated caller to supply model_id in a POST /v1/containers body and route the request through an arbitrary deployment UUID, bypassing the model-level access checks that only validate `model`. Removed the elif branch; operations without container_id (create, list) route by the caller-supplied `model` field as before. model_id forwarding is kept only inside the container_id block, where the proxy ownership check has already validated the container before forwarding the deployment ID. Adds a regression test pinning the security boundary: no-container-id path calls original_function directly even when model_id is in kwargs. Co-authored-by: Cursor <cursoragent@cursor.com> * test(containers): validate proxy-to-router model_id forwarding for managed IDs Add test_regression_get_container_forwarding_params_sets_model_id_for_managed_id to verify that get_container_forwarding_params (the proxy-side half of the Azure routing fix) correctly extracts and forwards model_id from a LiteLLM-managed encoded container ID. This closes the gap identified by Greptile P1: the previous regression test only injected model_id as a direct kwarg, validating the router in isolation. The new test exercises the actual proxy-to-router data flow through ownership.get_container_forwarding_params, confirming that kwargs["model_id"] is populated before _init_containers_api_endpoints is reached. Co-authored-by: Cursor <cursoragent@cursor.com> * fix(azure-containers): tighten endpoint-path strip to endswith match Use path.endswith() instead of path.find() for _AZURE_ENDPOINT_PATHS so the suffix strip only fires when api_base actually ends with one of the endpoint-specific path suffixes. This is the more precise check greptile flagged on the original find()-based implementation. * Fix sync container handler to preserve URL query string Mirror the async path fix: pass None instead of an empty params dict so httpx does not strip the URL's existing query string (e.g. ?api-version=...), which is required for Azure container routing. Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(azure-containers): strip trailing slash before endpoint suffix match Co-authored-by: Yassin Kortam <yassin@berri.ai> * fix(containers): recover model_id from stored encoded id for native Azure container IDs get_container_forwarding_params previously only set model_id when the user-supplied container_id was a LiteLLM-managed encoded id. For native upstream IDs (e.g. Azure 'cntr_<hex>') the decode fails and model_id was never forwarded — making the router-side fallback in _init_containers_api_endpoints unreachable in production. Fall back to the stored 'unified_object_id' on the ownership row, which is the encoded form captured at create time when the router selected a specific deployment. Decoding that yields the deployment model_id and restores router-based credential application (api_base, api_key) for retrieve/delete and container-file operations on native IDs.

Co-authored-by: Cursor <cursoragent@cursor.com> * fix(proxy): address Greptile review on batch file ID normalization Remove redundant resolve_* calls after update_batch_in_database and rename loop variable to avoid shadowing hidden_params unified_file_id. Co-authored-by: Cursor <cursoragent@cursor.com> * fix(tests): add mistral/ministral-8b-2512 to cost map and backfill in conftest Mistral rotated the 'mistral/mistral-tiny' alias to return 'ministral-8b-2512' as the response model, which was missing from the cost map. This caused test_completion_mistral_api and test_completion_mistral_api_modified_input to fail in litellm.completion_cost lookup. - Add mistral/ministral-8b-2512 entry to both the in-tree model_prices_and_context_window.json and the bundled litellm/model_prices_and_context_window_backup.json (mirrors the existing openrouter/mistralai/ministral-8b-2512 pricing). - litellm.model_cost is loaded at import time from the URL pinned to main, so the new backup entry isn't visible at test runtime until it also lands on main. Backfill any entries missing from the remote-fetched map into litellm.model_cost in the local_testing conftest so cost-calculator lookups succeed on this branch. * fix(tests): drop unnecessary del of conftest backfill loop vars * fix: resolve batch response file IDs even when status unchanged The status-unchanged early return in update_batch_in_database was skipping ensure_batch_response_managed_file_ids, leaving raw provider input_file_id (and other raw IDs) in the user-facing response when polling an in-progress batch.

Cursor Agent	7ba78155d7	fix(mcp): restrict passthrough probe challenge to OAuth passthrough servers ... The probe filter previously matched any server with Authorization in extra_headers, including gateway-managed OAuth2 servers. Those would then receive the resource_metadata= WWW-Authenticate challenge meant for pass-through servers, instead of the authorization_uri= challenge pointing at the gateway AS metadata.

Falling through would direct MCP clients at the gateway, which is not the authorization server for pass-through configs. - mcp_server_manager: Wrap _get_tools_from_server in startup tool name mapping with try/except. Since _get_tools_from_server now re-raises MCPUpstreamAuthError, an upstream 401 from a pass-through server at startup (when no user token is present) would otherwise abort the loop and leave subsequent servers unmapped.

milan-berri	0fb710400f	fix(spend_counter): seed Redis counter via SET NX to prevent cross-pod double-seed (#27854) ... * fix(spend_counter): seed Redis counter via SET NX to prevent cross-pod double-seed Symptom ------- Customers on multi-pod deployments see team `spend` jump to ~2x (or N x the pod count) shortly after a Redis cache miss / TTL expiry, triggering spurious "Budget Crossed" alerts and blocked requests until the value is manually reset. Root cause ---------- `SpendCounterReseed.coalesced` warmed the primary spend counter by calling `redis.async_increment(key, value=db_spend, refresh_ttl=True)`, which lowers to Redis `INCRBYFLOAT`. That is additive, not idempotent. The per-counter `asyncio.Lock` only coalesces seeders inside one process. With N pods sharing one Redis, on a cold key (cold start, TTL expiry, manual delete) every pod independently passes its lock + Redis re-check, reads the same `db_spend`, and issues `INCRBYFLOAT db_spend`. Final value: N x db_spend. Fix --- Use `redis.async_set_cache(key, value=db_spend, nx=True)` for the seed. SET NX is atomic across pods: exactly one writer initializes the key; losers read the winner's value via `async_get_cache`. This is the same idiom already used by `coalesced_window` in the same file, so the two seed paths are now consistent. Per-request deltas continue to use `INCRBYFLOAT` (correct - additive behaviour is what we want for increments, not for initial seed). Verification ------------ Live two-process repro against the same Postgres + Redis (DB spend = 506): Unpatched: 4/4 runs -> Redis counter = ~1012 (~2 x db_spend) Patched: 12/12 runs -> Redis counter = ~506 Unit tests (`test_proxy_server.py`): - New `test_primary_spend_counter_redis_concurrent_seed_does_not_double_seed` patches `_get_lock` to return a fresh lock per caller (otherwise the per-process lock masks the race), races two `coalesced` calls, and asserts final = 506 with exactly one of two SET NX attempts winning. - 4 existing tests updated for the new seed contract (SET NX for the seed, INCRBYFLOAT only for the per-request delta). - Full `spend_counter or reseed or budget` slice: 22 passed. Co-authored-by: Cursor <cursoragent@cursor.com> * test(spend_counter): make SET NX mock atomic so loser branch is exercised Greptile flagged that `redis_set_cache` in test_primary_spend_counter_redis_concurrent_seed_does_not_double_seed placed `await asyncio.sleep(0)` AFTER the NX membership check. Both concurrent tasks observed an empty `redis_store`, passed the guard, and both returned True - so the loser branch (else: read back winner's value) was never exercised. Fix the mock to model real atomic Redis SET NX: - Yield BEFORE the membership check so two concurrent callers interleave the way real SET NX does (first to resume runs check + write atomically and wins; second resumes after the key exists and loses). - Track set_cache return values; assert sorted([loser, winner]) so we know exactly one task wins and one loses. - Track async_get_cache calls that happen AFTER at least one SET NX has completed; assert at least one such read - that is the loser-path fallback (`current_value = float(cached)` when seeded is False). Verified by temporarily reverting the mock to the old order: the test now fails with `expected exactly one SET NX winner and one loser, got [True, True]`, exactly the failure mode Greptile described. No production code change. Co-authored-by: Cursor <cursoragent@cursor.com> * test(spend_counter): mock async_set_cache to populate redis_store in concurrent read+write test `test_concurrent_read_and_write_paths_share_one_db_query` mocks `async_increment` to populate the in-memory `redis_store`, but did not mock `async_set_cache`. After the SET-NX seed change in `coalesced()`, the seed step writes via `async_set_cache(nx=True)` (default AsyncMock, no `redis_store` write), so the simulated Redis stays empty after the first reseed. The second `get_current_spend` then sees a clean Redis miss, re-enters the DB read path, and the test fails with `expected 1 DB query, got 2`. Fix: add a `redis_set_cache` side_effect that updates `redis_store` on `nx=True` (and rejects when the key already exists), matching the pattern used by the four sibling tests fixed in this branch's first commit. Pre-existing assertions are unchanged. Full `tests/test_litellm/proxy/test_proxy_server.py`: 158 passed.

Cursor Agent	f0eb54ea9f	fix(mcp): correct passthrough probe 401 + slashed-name cold start parser ... - _check_passthrough_upstream_auth now emits 'Bearer resource_metadata="..."' pointing at the gateway's oauth-protected-resource well-known URL, mirroring the pre-emptive 401 path. Pass-through servers don't use the gateway as an authorization server, so the previous 'authorization_uri=' challenge sent clients to the wrong metadata endpoint. - _parse_mcp_server_names_from_path now accepts server names that contain a single slash (e.g. custom_solutions/user_123), mirroring MCPRequestHandler._extract_target_server_names_from_path. Without this, the cold-start bypass missed slashed-name servers and the generic admission error propagated instead of the spec-compliant 401 challenge. - _is_mcp_passthrough_cold_start drops the unused scope parameter from its signature.

Claude	ee38ba16e3	fix(mcp,tests): sync stubs and cold-start assertions with delegate-check ... The merge of base-branch _target_servers_delegate_auth_to_upstream into process_mcp_request inserts an additional get_mcp_server_by_name(name) lookup ahead of the cold-start path, which breaks two test patterns: 1. lookup_by_name(name) side-effect stubs in TestMCPDelegateAuthToUpstream are called positionally by the delegate check, then again by the cold-start path with client_ip=... — raising TypeError: unexpected keyword argument 'client_ip'. Accept **_kwargs to match the real signature. 2. TestMCPPassthroughColdStartAdmission assertions count the lookup exactly once with client_ip=..., but the delegate check now adds a positional-only call ahead of it. Switch assert_called_once_with to assert_any_call for the cold-start invocation, and assert client_ip was *not* passed for the aggregate /mcp test where cold-start must not fire. Both updates align with CLAUDE.md guidance to keep monkeypatch stubs in sync with the real signature when an optional parameter is added.

The regex previously truncated at the first comma and silently passed a single server name to the cold-start gate. - Switch _is_mcp_passthrough_cold_start to all-targets semantics, matching _target_servers_use_oauth2: one non-passthrough target in a co-targeted set must not flip the anonymous-admission bypass open for the others. - Drop the redundant HTTPStatusError block in _extract_upstream_auth_failure - any HTTPStatusError carries a .response, so the preceding generic block already handles 401/403 detection.

It was falling through to the generic handler and surfacing as an opaque 500. Mirror the REST endpoint behavior: translate MCPUpstreamAuthError into an HTTPException(status_code=e.status_code) with the upstream www-authenticate header so standards-compliant MCP clients trigger the upstream OAuth flow.

Add the entry mirroring the existing openrouter/mistralai/ministral-8b-2512 pricing. * test(cost_calculator): assert output_cost_per_reasoning_token for gemini-3.1-flash-lite * fix(tests): backfill local backup entries into runtime model_cost litellm.model_cost is loaded from LITELLM_MODEL_COST_MAP_URL (pinned to main) at import time, so any pricing entries added to the in-tree backup on this branch aren't visible at test runtime until they also land on main. The Mistral cassette currently returns model=ministral-8b-2512 and the cost-calculator lookup in test_completion_mistral_api / test_completion_mistral_api_modified_input fails despite the entry existing in the local backup. Backfill missing backup entries into litellm.model_cost in the local_testing conftest so these lookups succeed against the cassette state the branch is being tested with. * fix(tests): guard conftest backfill against empty local cost map --------- Co-authored-by: Cursor <cursoragent@cursor.com> Co-authored-by: mateo-berri <277851410+mateo-berri@users.noreply.github.com>	2026-05-20 10:03:14 -07:00
Claude	a6492bf424	fix(auth): address remaining greptile style findings ... - get_request_route: require root_path to match whole path segments before stripping, so '/apifoo' isn't truncated to 'foo' when root_path='/api'. - get_mcp_client_ip: collapse the two trusted-proxy validation branches into a single is_request_from_trusted_proxy call so the return value drives control flow instead of being discarded for the side-effect warning.

Claude	1e5053adf1	fix(mcp,auth): restore client_ip in oauth2 target check, drop from delegate check ... The merge of staging into the PR branch (d42a66adb6) misplaced the client_ip=client_ip kwarg: it landed inside _target_servers_delegate_auth_to_upstream (which never accepted client_ip and isn't called with it), while the sibling _target_servers_use_oauth2 has client_ip in its signature but stopped passing it through to get_mcp_server_by_name. That left ruff flagging F821 on the undefined name and lint failing. Move client_ip back into _target_servers_use_oauth2's lookup (matching the call site that already forwards IPAddressUtils.get_mcp_client_ip) and drop it from _target_servers_delegate_auth_to_upstream so its body matches its signature again.	2026-05-20 16:37:02 +00:00
Claude	488fcc25e1	fix(jwt,mcp): fall back to global JWKS on unknown issuer; prune fetch locks ... - handle_jwt._get_configured_issuer now returns None for tokens whose 'iss' is not in the configured issuers list, letting auth_jwt fall through to the legacy JWT_PUBLIC_KEY_URL path instead of hard-raising. This keeps existing tokens from non-configured IdPs working when an operator adds the new 'issuers' list to a live deployment. - discoverable_endpoints._prune_oauth_metadata_cache now also prunes entries in _OAUTH_METADATA_FETCH_LOCKS whose cache entry has been evicted and whose lock isn't currently held, bounding the locks dict to match the cache it guards.

Claude	22e9064673	fix(mcp,jwt): address greptile concurrency and code-quality concerns ... - _apply_issuer_claim_mappings now builds a new dict and reads from the original token, rather than mutating its input. The change is behaviour-preserving (caller passes a fresh jwt.decode result), but avoids the surprise-mutation pattern flagged by greptile. - is_network_error uses isinstance(exc, httpx.TransportError) instead of matching type(exc).__name__ against a hand-maintained string set, so ReadError / WriteError / ProxyError / etc. are also treated as transport-level failures and surfaced as HTTP 502. - fetch_upstream_oauth_protected_resource now coalesces concurrent discovery requests per (server_id, resource_url) through an asyncio.Lock so concurrent .well-known calls share a single upstream fetch + cache write. - Drop the redundant 'if trusted_ranges:' branch in get_mcp_client_ip; it is always true on the path that reaches it (the prior 'if not trusted_ranges:' early-returns).

Claude	087a4da116	fix(tests): backfill local model_cost into remote-fetched map ... litellm.model_cost is loaded at import time from LITELLM_MODEL_COST_MAP_URL (pinned to main), so pricing entries that exist only in this branch (e.g. mistral/ministral-8b-2512, freshly added because Mistral's API now returns this id from mistral-tiny) are absent at test time and completion_cost lookups raise 'This model isn't mapped yet'. Backfill the in-tree backup into litellm.model_cost in the local_testing conftest so cassette-driven cost calculations resolve against the entries that ship with the branch under test. Fixes local_testing_part1 failures on test_completion_mistral_api and test_completion_mistral_api_modified_input.	2026-05-20 16:17:56 +00:00
Claude	fc31a07013	Merge remote-tracking branch 'origin/litellm_feat/v1.84.0-mcp-gateway-jwt-auth' into litellm_feat/v1.84.0-mcp-gateway-jwt-auth ... # Conflicts: # litellm/proxy/management_endpoints/mcp_management_endpoints.py	2026-05-20 16:00:27 +00:00
Claude	d42a66adb6	Merge branch 'litellm_internal_staging' into litellm_feat/v1.84.0-mcp-gateway-jwt-auth ... Resolved unrelated-history merge using e1fc955464 (the original base of upstream PR #28008) as the 3-way merge base. Conflict resolutions: - discoverable_endpoints.py: kept PR's _OAUTH_METADATA_CACHE / prune helpers and PR's inline redirect_uri extraction in /callback; took staging's callback comment that mentions the ops-allowlist code path served by validate_trusted_redirect_uri. - oauth_utils.py: took staging's version (strict superset: adds MCP_TRUSTED_REDIRECT_ORIGINS ops allowlist, userinfo/backslash netloc rejection, rejection diagnostics). - server.py: kept both PR's _raise_preemptive_401_for_unauthenticated_servers and staging's _get_forwarded_auth_from_scope / _probe_upstream_auth / _check_passthrough_upstream_auth additions (independent helpers). - mcp_management_endpoints.py: took staging's verify_exp=False JWT decode option and staging's delegate_auth_to_upstream PKCE bypass block. - proxy_server.py: took staging's restructured 4-case dynamic_mcp_route, and ported PR's scope['_original_path'] preservation into _mcp_forward_as_path so server.py's OAuth-challenge URL selection still has the public request path. - types/mcp_server/mcp_server_manager.py: kept both PR's is_oauth_passthrough and staging's has_token_exchange_config properties (additive). - test_image_edits.py: took staging's _make_test_images() per fix(image_edits). - test_realtime_guardrails_openai.py: took staging's unicode-punctuation normalization. - test_fireworks_ai_translation.py: took staging's mocked-payload test_document_inlining_example. - test_openapi_compliance.py: kept PR's removal of 'steps' per fix(interactions). - test_discoverable_endpoints.py: took staging's tests (PR's tests assumed the removed get_proxy_base_url import path). - test_mcp_server.py: took staging's pre-flight upstream-auth tests (cover the helpers we kept). - test_mcp_management_endpoints.py: took staging's verify_exp=False / delegate_auth_to_upstream tests, and also kept PR's test_mcp_oauth_authorize_token_routes_use_browser_auth_dependency (independent route-wiring assertion).

Claude (greptile fixer)	298936f83d	fix(mcp,auth): address greptile review concerns ... - handle_sse_mcp now calls _raise_preemptive_401_for_unauthenticated_servers so SSE clients to pass-through OAuth MCP servers receive the RFC 9728 401 + WWW-Authenticate challenge that the streamable-HTTP path already emits. - get_request_route strips a trailing slash from root_path before length-based prefix removal so non-canonical ASGI root_path values like "/litellm/" don't strip the leading slash from the returned route. - _mcp_oauth_user_api_key_auth's cookie JWT decode now passes options={"verify_aud": False} so a future revision of the UI session JWT containing an aud claim cannot silently downgrade the request to unauthenticated.

Claude	76c704be34	fix(model_prices): register mistral/ministral-8b-2512 ... Mistral's API now returns model='ministral-8b-2512' when 'mistral-tiny' is requested, so test_completion_mistral_api fails with 'This model isn't mapped yet'. Adding the entry so completion_cost can resolve the cost for that response. Author: Claude <noreply@anthropic.com>	2026-05-20 15:26:24 +00:00
yuneng-jiang	37845acb57	fix(tests): migrate realtime + rerank tests off shut-down upstream models (#28191) ... * fix(tests): use gpt-realtime in realtime guardrails test OpenAI shut down gpt-4o-realtime-preview-2024-12-17 on 2026-05-07, so the live OpenAI realtime guardrails integration test now fails with model_not_found (session.created never arrives, _wait_for_event times out). Point OPENAI_REALTIME_URL at the current GA model, gpt-realtime. Scope limited to this test: the pricing-catalog JSON keeps the retired entries intentionally (historical cost calc + separate Azure timeline), and the Azure realtime cost-calc test is unaffected. * fix(tests): mock nvidia_nim rerank instead of hitting EOL'd endpoint NVIDIA reached end-of-life for the hosted nvidia/llama-3.2-nv-rerankqa-1b-v2 rerank API on 2026-05-18 with no published replacement, so the live BaseLLMRerankTest.test_basic_rerank for nvidia_nim now returns HTTP 410 ("Gone"). NVIDIA's hosted catalog rotates on a schedule, so swapping in another live model would only defer the failure. Override test_basic_rerank in TestNvidiaNim to mock the sync/async HTTP transport (same pattern as test_nvidia_nim_rerank_ranking_endpoint in this file) and inject a fake NVIDIA_NIM_API_KEY via monkeypatch. The request/response transformation and cost calculation stay covered offline. Scope limited to nvidia_nim; other BaseLLMRerankTest providers untouched. * fix(tests): migrate remaining realtime tests off shut-down gpt-4o-realtime-preview OpenAI's 2026-05-07 shutdown removed the entire gpt-4o-realtime-preview family, including the undated 'gpt-4o-realtime-preview' alias (not just the dated snapshot fixed earlier). Three live tests still connected with the dead alias and failed with messages_received=1 (an error event instead of session.created): - test_openai_realtime_simple.py: get_model() -> gpt-realtime (drives TestOpenAIRealtime.test_realtime_connection / test_realtime_with_query_params) - test_openai_realtime.py: test_openai_realtime_direct_call_no_intent and test_openai_realtime_direct_call_with_intent -> openai/gpt-realtime (the with_intent test shares the same dead alias even though it was not in the failing set this run) Mocked unit tests (test_realtime_query_params_construction, test_realtime_query_params_use_normalized_model_name) are left as-is: they never hit the network and assert string plumbing only. Also fixes test_text_message_blocked_by_guardrail_no_ai_response, which now connects (the earlier URL swap worked) but tripped a model-wording-brittle assertion. The guardrail flow asks the model to voice the block message verbatim; gpt-4o-realtime-preview complied (output contained 'blocked'), gpt-realtime refuses verbatim-repeat instructions ('I'm sorry, but I can't repeat that message.'). Since the original user message is blocked before it reaches OpenAI, the refusal is still a safe outcome. Assertion #3 now accepts both voicing and refusal, and adds a hard check that the blocked phrase never leaks into AI output. (cherry picked from commit ce87c411bf)	2026-05-20 15:25:30 +00:00
yuneng-jiang	c65e598402	fix(tests): replace shut-down gpt-4o-audio-preview with gpt-audio-1.5 (#28281) ... * fix(tests): replace shut-down gpt-4o-audio-preview with gpt-audio-1.5 OpenAI shut down gpt-4o-audio-preview on 2026-05-07, so the live audio calls in test_stream_chunk_builder_openai_audio_output_usage and test_standard_logging_payload_audio now hard-fail with a model-not-found error on every PR. The error was not "openai-internal", so the except block swallowed it and execution fell through to an unbound completion/response (UnboundLocalError). Switch both tests to gpt-audio-1.5, OpenAI's recommended successor (GA, not deprecated, already present in the litellm cost map so the response_cost assertion still resolves). Also broaden the except to skip with the real error in the reason instead of crashing, so a transient upstream blip can't reintroduce the UnboundLocalError. * fix(tests): narrow audio-test skip to model-not-found, re-raise the rest Address review feedback: an unconditional skip on any exception would silently mask a litellm-internal regression in the audio path (broken param transformation, serialization, bad header) instead of failing CI. Skip only on the upstream-unavailable class (model_not_found / "does not exist" / openai-internal) and re-raise everything else, so genuine regressions still fail loudly. The UnboundLocalError is still fixed because the handler either skips or raises - it never falls through. * fix(tests): add budget_exceeded to expected Interaction status enum Staging added budget_exceeded to the Interaction OpenAPI status enum; the staging merge into this branch picked up the spec change but not the matching test update, so test_status_enum_values failed in CI. Align the test's expected list (exact-match by design) with the live spec. * fix(tests): mock HTTP fetch in test_img_url_token_counter The test parameterized a live third-party image URL (blog.purpureus.net) which now 404s, causing get_image_dimensions to fall through to its base64 decode path and crash with 'not enough values to unpack' on every PR run. Mock safe_get with a tiny 1x1 PNG so the URL branch is still exercised without any network dependency. * fix(tests): swap gpt-4o-audio-preview to gpt-audio-1.5 in test_gpt4o_audio OpenAI shut down gpt-4o-audio-preview on 2026-05-07, so both live tests in test_gpt4o_audio.py (test_audio_output_from_model and test_audio_input_to_model) hard-fail model_not_found on every PR. Swap the hardcoded model to OpenAI's successor gpt-audio-1.5 (same chat-completions audio surface; already in the litellm cost map). Mirror the narrowed-skip pattern from the prior audio fixes: skip on model_not_found / does-not-exist / openai-internal, re-raise everything else so genuine litellm regressions still fail CI loudly.

Yuneng Jiang	76700e7bb3	test(fireworks): mock remaining live smoke tests ... test_completion_fireworks_ai and test_completion_cost_fireworks_ai made real Fireworks calls and broke whenever Fireworks rotated its serverless catalog (no externally-verifiable model list exists). They also asserted nothing — just printed. Mock the HTTP post and assert real behavior instead: the request is built with the right model/messages and the OpenAI-compatible response parses back; the cost path yields a non-zero cost against the local cost map. No network, no model dependency, stronger than the old smoke checks. (cherry picked from commit b5db7ed37d)	2026-05-20 15:24:49 +00:00
Yuneng Jiang	a0b61f6dcb	test(fireworks): replace deprecated llama-v3p3-70b-instruct model ... Fireworks removed llama-v3p3-70b-instruct from serverless, so every live test using it now fails with NotFoundError ("Model not found, inaccessible, and/or not deployed"). Swap the 6 references (3 files) to the currently-served accounts/fireworks/models/deepseek-v3p1 — the canonical model in Fireworks' current docs examples and present in LiteLLM's cost map. test_get_model_params_fireworks_ai is a pure pricing-heuristic test (no network) asserting the >16b branch, so it uses llama-v3p1-70b- instruct instead to keep the "fireworks-ai-above-16b" assertion and branch coverage intact. (cherry picked from commit 39a1d438f2)	2026-05-20 15:24:45 +00:00
Yuneng Jiang	93d3ed7ee5	fix(tests): drop dall-e-only test classes; route live image tests via gpt-image-1 ... Second wave of failures from the 2026-05-12 DALL-E shutdown: - tests/image_gen_tests/test_image_edits.py::TestOpenAIImageEditDallE2 and tests/image_gen_tests/test_image_generation.py::TestOpenAIDalle3 are explicitly named for the deprecated models and can't pass; remove. gpt-image-1 coverage already exists in sibling classes. - tests/local_testing/test_router.py image gen tests use dall-e-3 only as a routing example; swap to gpt-image-1. - tests/local_testing/test_custom_callback_input.py image_generation success/failure paths swapped to gpt-image-1.

yuneng-jiang	a119324127	test: replace dall-e-3 with gpt-image-1 in health check and router tests (#27813) ... OpenAI returns 'The model dall-e-3 does not exist' for the test account, breaking test_openai_img_gen_health_check and test_image_generation. Switch to gpt-image-1, matching the existing TestOpenAIGPTImage1 pattern. (cherry picked from commit aee58db880)	2026-05-20 15:24:38 +00:00
