The two mutating endpoints in team_callback_endpoints.py
(``/team/{id}/callback`` POST and ``/team/{id}/disable_logging``) wrote
team metadata without emitting an audit-log row. The disable variant
is the worst case: a logging-control action that itself isn't logged,
so an admin (or compromised admin) could zero out a team's
observability with no forensic trail.
Add ``_emit_team_callback_audit_log`` mirroring the
``store_audit_logs``-gated pattern already used in team_endpoints.py
for /team/new and /team/update. When ``litellm.store_audit_logs`` is
True, both endpoints now emit an ``LiteLLM_AuditLogs`` row capturing
the calling user, the API key, and the before/after team metadata.
When the flag is False the helper is a no-op, so non-Enterprise
deployments are unaffected.
The ``litellm_changed_by`` header is now also accepted on
``/team/{id}/disable_logging`` to match the existing
``add_team_callbacks`` shape; the header is optional so existing
callers are unaffected.
Variant scope: the file has three endpoints — both mutating variants
are now logged. The read-only ``GET /team/{id}/callback`` is unchanged.
Other unlogged callback / logging-control admin endpoints elsewhere in
the proxy (e.g. ``/cache/settings``, ``/config_overrides/hashicorp_vault``)
are out of scope here and would be addressed in a separate PR.
Tests cover both endpoints in both ``store_audit_logs`` states and
verify that the captured before/after metadata reflects the actual
mutation, plus that the ``litellm-changed-by`` header overrides the
auth user_id when supplied.
PR #26484 substitutes LITELLM_PROXY_MASTER_KEY_ALIAS for
hash_token(master_key) in UserAPIKeyAuth so the master key (or its
hash) never reaches spend logs / metrics. The otel prometheus tests
still hardcoded the SHA-256 of "sk-1234"
("88dc28d0f030c55ed4ab77ed8faf098196cb1c05df778539800c9f1243fe6b4b"),
so the metric labels no longer matched and test_proxy_failure_metrics
failed. Reference the alias constant directly.

npm's `min-release-age` config has type `[null, Number]`. The value `3d`
parses to NaN, which propagates into `before = new Date(NaN)` (Invalid
Date). Pacote then calls `.toISOString()` on it and throws
`RangeError: Invalid time value`, breaking every local `npm install`.
Drop the `d` suffix in all six `.npmrc` files. The `<days>` in npm's
type hint is a label, not part of the value.
This is a no-op for CI (`npm ci` ignores this setting per the comment
in the file) but unblocks local `npm install`.
Strip module-level docstrings and per-test/per-block prose from the
LIT-2642 fix and tests. Keep one short comment in each streaming site
that flags the GeneratorExit-vs-Exception subtlety, since that's the
non-obvious reason the flush lives in finally rather than after the loop.
Pure cleanup; no behavior change. All 12 regression tests still pass.

When a client disconnects mid-stream from a Bedrock pass-through endpoint,
Starlette calls aclose() on the async generator, raising GeneratorExit
(a BaseException, not Exception) at the suspended yield. The previous
`except Exception` blocks in _async_streaming/_sync_streaming
(litellm/passthrough/main.py) and PassThroughStreamingHandler.chunk_processor
did not catch GeneratorExit, so the post-loop flush that hands collected
raw bytes to async_flush_passthrough_collected_chunks /
_route_streaming_logging_to_handler never ran. All per-chunk usage data
was silently dropped, undercounting spend for interrupted Bedrock invoke
and converse streams.
Move the flush into a finally block in all three sites and guard with a
`flush_scheduled` flag so the success path still flushes exactly once.
Also pull raise_for_status() out of the chunk-collection try block in
_async_streaming so 4xx/5xx responses still raise and don't enter the
flush path with zero bytes (preserving the behavior tested by
test_async_streaming_error_propagation.py).
Add regression coverage:
- test_async_streaming_flushes_on_client_disconnect
- test_async_streaming_flushes_on_upstream_exception_with_partial_data
- test_sync_streaming_flushes_on_early_close
- test_chunk_processor_logs_on_client_disconnect
plus baseline tests for normal completion and the 4xx no-flush path.
Fixes LIT-2642.

After dedaf74a5e, _async_retrieve_batch wraps the GET in async_safe_get,
which inspects response.is_redirect. test_avertex_batch_prediction's
MagicMock response left is_redirect unset, so it auto-generated a truthy
mock, sent the redirect-follow loop into _extract_redirect_url, and
httpx.URL().join(<MagicMock>) raised TypeError. Set is_redirect=False
so the response is treated as terminal.
* chore(auth): validate clientside api_base against SSRF guard; clear admin secrets on base override
Two related issues with how the proxy handles client-supplied
``api_base`` / ``base_url`` overrides on chat-completion requests:
1. **SSRF gate bypass** — ``check_complete_credentials()`` returned
``True`` for any non-empty ``api_key``, allowing the
``is_request_body_safe`` ``banned_params`` loop to admit ``api_base``
/ ``base_url`` values that point at private (RFC 1918), loopback,
link-local, or cloud-metadata addresses. Now: when the gate sees a
client-supplied ``api_base`` / ``base_url``, it runs the URL through
``litellm_core_utils.url_utils.validate_url`` (DNS-resolves, blocks
internal/IMDS/LL networks, defends against rebinding). Rejection
raises with a clear message.
2. **Admin-config leak on base override** —
``get_dynamic_litellm_params`` only carried the three clientside keys
(``api_key``, ``api_base``, ``base_url``) from request to upstream
call. Other admin-configured fields on ``litellm_params`` —
``organization``, ``extra_body``, ``extra_headers``, ``api_version``,
``azure_ad_token``, AWS / Vertex creds, etc. — flowed through
unchanged. With base redirected to a client-controlled server, those
admin secrets were sent to the attacker. Now: when ``api_base`` /
``base_url`` is in ``request_kwargs``, drop those admin-config
fields from ``litellm_params`` unless the caller re-supplied them.
Tests cover the SSRF-target rejection per URL field, the admin-secret
clearing on base override, the don't-clear case when only ``api_key``
is overridden (BYOK pattern), and the don't-overwrite case when the
caller resupplies fields like ``organization`` themselves.

* chore(vertex-batches): wrap api_base GET in safe_get for defense-in-depth
The vertex batches status-poll fetches an attacker-influenceable
``api_base`` URL with a raw ``sync_handler.get()``. The proxy auth gate
already validates clientside ``api_base`` before reaching this sink, so
the proxy flow is covered. This adds the per-sink wrap so SDK callers
and any future code path that bypasses the proxy gate pick up the same
SSRF defense from ``url_utils.safe_get``.
Operators with a legitimate private Vertex base can either allowlist
the host via ``litellm.user_url_allowed_hosts`` or disable validation
with ``litellm.user_url_validation = False``.

* refactor(auth): hoist url_utils import; derive admin-config field list from CredentialLiteLLMParams
/simplify pass:
- Move ``from litellm.litellm_core_utils.url_utils import SSRFError, validate_url``
to module top in ``proxy/auth/auth_utils.py``. CLAUDE.md prefers
module-level imports unless avoiding a circular dependency, and
there's no cycle here (``url_utils`` doesn't depend on ``proxy.auth``).
- Replace the hardcoded ``_ADMIN_CONFIG_FIELDS_TO_CLEAR_ON_BASE_OVERRIDE``
literal with ``_admin_config_fields_to_clear_on_base_override()`` that
derives the typed-field portion from
``CredentialLiteLLMParams.model_fields``. Adds three fields the
hardcoded list missed (``aws_bedrock_runtime_endpoint``,
``watsonx_region_name``, ``region_name``) and stays in sync as new
provider fields are declared on the model. The kwargs-only set
(``organization``, ``extra_body``, ``azure_ad_token``, ``aws_session_token``,
``aws_sts_endpoint``, ``aws_web_identity_token``, ``aws_role_name``, …)
remains explicit since those fields aren't on the typed model.

* fix(auth): close field-echo bypass; gate URL check on toggle; cover async batch path
Three issues from review:
1. ``get_dynamic_litellm_params`` used ``if field not in request_kwargs:
pop`` to clear admin-set provider config when the caller redirected
``api_base``. A caller could *echo* any clear-list field name (with any
value, including an empty string) to skip the pop, leaving the admin's
value in ``litellm_params`` to be forwarded to the redirected upstream.
Fix: always pop, then write the caller's value back if they resupplied
the field.
2. ``check_complete_credentials`` called ``validate_url`` directly. That
helper doesn't itself consult ``litellm.user_url_validation``; the
toggle is honoured by ``safe_get`` / ``async_safe_get``. Mirror that
here so admins who explicitly disabled URL validation aren't blocked
at the proxy boundary.
3. ``VertexAIBatchesHandler._async_retrieve_batch`` still used a bare
``await client.get(api_base, ...)`` while the sync sibling was wrapped
in ``safe_get``. Wrap the async call in ``async_safe_get`` so SDK
callers on the async path get the same DNS-rebind / private /
cloud-metadata defenses as the sync path.
Tests:
- ``TestCheckCompleteCredentialsBlocksSSRF`` is now mock-only; an autouse
fixture flips the toggle on, ``validate_url`` is patched in the
parametrized blocking tests, and the positive path no longer makes a
real DNS call to api.openai.com.
- ``test_skips_url_validation_when_toggle_is_off`` documents the new
toggle-off behaviour and asserts ``validate_url`` is not called.
- ``test_caller_resupplied_value_overrides_admin_value_on_base_override``
replaces the prior test that asserted the buggy
preserve-admin-value-on-echo behaviour.
- ``test_field_echo_does_not_preserve_admin_value`` is a focused
regression test for the empty-string echo vector.

* fix(auth): close provider-confusion credential exfil; expand banned-params; cover OCI
Three additions on top of the entry-point URL gate so the cluster is
fully closed against caller-supplied ``api_base`` redirection:
1. ``get_llm_provider_logic.py`` matched registered openai-compatible
endpoints against ``api_base`` with an unanchored substring search
(``if endpoint in api_base:``). A caller could pass an api_base like
``https://attacker.com/api.groq.com/openai/v1`` to coerce the proxy
into reading ``GROQ_API_KEY`` from the environment and forwarding it
as a Bearer credential to the attacker's host. Replaced with parsed-
URL semantics (hostname exact-match plus segment-bounded path-prefix)
in a new ``_endpoint_matches_api_base`` helper.
2. ``is_request_body_safe`` rejects ``api_base`` / ``base_url`` /
``user_config`` / a handful of AWS / vertex fields, but the list
omitted three other endpoint-targeting fields:
* ``aws_bedrock_runtime_endpoint`` — Bedrock endpoint redirect
* ``langsmith_base_url`` / ``langfuse_host`` — observability callback
hostnames; attacker-controlled values exfiltrate the entire request
payload (incl. message content) via the logging hook.
Added all three to the blocklist.
3. ``_admin_config_fields_to_clear_on_base_override`` derives its typed-
field list from ``CredentialLiteLLMParams.model_fields``, which does
not declare any of the OCI provider's auth fields. Added
``oci_signer``, ``oci_user``, ``oci_fingerprint``, ``oci_tenancy``,
``oci_key``, and ``oci_key_file`` to the kwargs-only fixed list so
they are cleared on caller-redirected ``api_base`` like the AWS /
Azure / Vertex equivalents.
Tests:
- ``TestEndpointMatchesApiBase`` — direct unit tests on the new
matcher: legitimate provider URLs (5 shapes) match; attacker
smuggling via path injection, suffix label, prefix label, userinfo
``@`` injection, and path-segment lookalikes (7 shapes) do not.
- ``TestGetLlmProviderRejectsAttackerSmuggledApiBase`` — end-to-end
invariant that ``GROQ_API_KEY`` is never read against an attacker-
controlled host while the legitimate ``api.groq.com`` path still
resolves the provider correctly.
- ``TestIsRequestBodySafeBlocksEndpointTargetingFields`` — parametrized
coverage that each of the three new banned-params raises a clear
rejection naming the offending field.

* fix(auth): remove implicit api-key bypass + add posthog/braintrust/slack to blocklist
The historical ``check_complete_credentials`` clause inside
``is_request_body_safe`` was a third, *implicit*, *caller-controlled*
BYOK path: any caller that supplied a non-empty ``api_key`` caused the
entire banned-params blocklist to be skipped. That turned every missing
entry on the blocklist into an exploitable SSRF / credential-exfil hole
and is the root cause of the chain of api_base advisories that have
been re-discovered with each new integration:
* GHSA-jh89-88fc-qrfp (critical, triage) — env-var exfil via api_base
* GHSA-3frq-6r6h-7j64 (high, triage) — admin org / extra_body leak
* veria-admin Dv_m860l, b_yRJeQ5, stN90yjP, LBlyOAc8, U2TD78kg —
variations on "list X is missing field Y"
Two explicit, admin-controlled BYOK paths already exist and remain:
``general_settings.allow_client_side_credentials = true`` (proxy-wide)
and ``configurable_clientside_auth_params: [...]`` per deployment.
Removing the implicit bypass converts the failure mode of a missing
blocklist entry from "live credential leak" to "predictable 400 with
a clear remediation message," which is the structural fix.
Also adds the three remaining endpoint-targeting fields the dynamic
callback layer reads from request body: ``posthog_host``,
``braintrust_host``, ``slack_webhook_url``. ``slack_webhook_url`` in
particular was a direct exfil channel (caller-set webhook → proxy
mirrors every request to attacker's Slack).
Tests:
- ``test_api_key_does_not_bypass_blocklist`` — parametrized regression
asserting api_key=anything no longer skips the gate for any of the
five highest-risk fields.
- ``test_admin_opt_in_proxy_wide_still_allows`` — confirms the
documented BYOK opt-in still works.
- Extends ``test_endpoint_targeting_field_in_request_body_is_rejected``
to cover posthog / braintrust / slack.

* fix(auth): block sagemaker_base_url, s3_endpoint_url, deployment_url
Provider-specific endpoint overrides surfaced by a wider audit of
``optional_params`` consumers in ``litellm/llms/``. Same threat as
``api_base``: a caller-supplied value redirects the outbound request
to an attacker host.
* ``s3_endpoint_url`` — read in ``litellm/llms/bedrock/files/transformation.py``
to build the S3 upload URL for Bedrock files. Caller redirects file
uploads to attacker-controlled S3.
* ``sagemaker_base_url`` — read in ``litellm/llms/sagemaker/{chat,completion}/*``.
Caller redirects SageMaker traffic. This is the primary vector
described in veria-admin mNqEBBtG.
* ``deployment_url`` — popped in ``litellm/llms/sap/chat/transformation.py``.
Caller redirects SAP deployment requests.
Tests parametrize ``test_endpoint_targeting_field_in_request_body_is_rejected``
to cover the three new fields.

Read user_id and team_id from the request's litellm_params metadata when
fabricating the UserAPIKeyAuth handed to the managed_files hook, so
batches created via passthrough are attributed to the real requester
instead of a hardcoded fallback. Adds parametrized regression coverage
for both the populated-metadata and empty-kwargs cases.
Use key-in-dict membership instead of truthy value lookup so explicitly
supplied empty/falsy payloads still trigger the permission check.
Adds parametrized regression coverage across all gated keys.
Resolves merge conflict in tests/test_litellm/llms/bedrock/chat/test_converse_transformation.py
by keeping both the new bedrock tool-result file/document tests and the
transform_response body-leak regression test.
Also addresses Greptile P2 comment: when BedrockImageProcessor returns a
block with neither 'image' nor 'document' keys on the tool-result path
(image_url and file content types), log a warning instead of silently
dropping the block.

AWS Bedrock pricing publishes a separate 1-hour prompt-cache write rate for
Claude 4.5 / 4.6 / 4.7 (1.6x the 5-minute rate). Without
`cache_creation_input_token_cost_above_1hr`, cost tracking for 1-hour-TTL
prompt caching on Bedrock falls back to the 5-minute rate and undercounts
spend by ~60%.
Adds the field to the spot-checked Global and US-region entries:
- anthropic.claude-opus-4-7 (Global $10.00 / MTok)
- anthropic.claude-opus-4-6-v1 (Global $10.00 / MTok)
- anthropic.claude-opus-4-5-... (Global $10.00 / MTok)
- anthropic.claude-sonnet-4-6 (Global $6.00 / MTok)
- anthropic.claude-sonnet-4-5-... (Global $6.00 / MTok regular,
$12.00 / MTok long-context >200K)
- anthropic.claude-haiku-4-5-... (Global $2.00 / MTok)
- global.anthropic.* mirrors of the above
- us.anthropic.* mirrors at the US +10% premium
Also updates the long-context (>200K) variants of Sonnet 4.5 with
`cache_creation_input_token_cost_above_1hr_above_200k_tokens`.
The mirrored entries in `litellm/model_prices_and_context_window_backup.json`
are updated in lockstep.
EU / AU / APAC / JP / us-gov regional variants are out of scope for this
change pending separate verification against AWS Bedrock pricing for those
regions.
Adds tests/test_litellm/test_bedrock_anthropic_1hr_cache_pricing.py to lock
in the expected values and the 1.6x ratio invariant.

Two issues from the previous push's review:
1. **Greptile P1**: ``get_vector_store_info`` had the same catch-all
``except Exception`` pattern as ``update_vector_store``, so the
HTTPException(403/404) raised by both the in-memory access check and
the new ``_fetch_and_authorize_vector_store`` helper was rewritten as
500. Mirror the ``except HTTPException: raise`` guard from
``update_vector_store``.
2. **code-quality CI** (``tests/code_coverage_tests/recursive_detector.py``)
flagged ``_redact_sensitive_litellm_params`` as an unallowlisted
recursive function. Match the convention of other allowlisted
helpers ("max depth set"): bound recursion at depth 10 (well above
any plausible nesting level for real ``litellm_params`` payloads),
return the redaction sentinel on overflow, and add the function
name to ``IGNORE_FUNCTIONS``.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Three issues surfaced in review of the previous commit:
1. **Veria — Medium**: ``litellm_params`` carries a nested
``litellm_embedding_config`` dict (auto-resolved from the model
registry on create / update) which itself holds ``api_key`` /
``aws_*`` / ``vertex_credentials``. The previous redactor only
inspected top-level keys, so the nested values passed through
unredacted. Recurse into nested dicts.
2. **Greptile — P2**: when ``litellm_params`` is a JSON-serialized
string (the in-memory registry occasionally stores it that way), the
previous redactor silently no-op'd via the ``isinstance(..., dict)``
guard and echoed the raw payload back. Now: parse, redact, re-serialize.
If the string is not valid JSON, replace it with the redaction
sentinel rather than echo it.
3. **mypy** flagged ``_redact_sensitive_litellm_params``'s
``Optional[Dict[str, Any]]`` signature as incompatible with the
``object``-typed call site. Widened to ``Any -> Any`` to reflect the
actual contract (the function now handles dict / str / None / other).
Also fixes a related test regression in
``test_remove_sensitive_info_from_deployment_with_excluded_keys``: the
``"credentials"`` plural addition to ``SensitiveDataMasker`` defaults
caused the first call (without ``excluded_keys``) to mutate the input
dict's ``litellm_credentials_name`` to a masked value. The second call
(with ``excluded_keys``) then saw the already-masked value rather than
the original. Construct fresh input for each call.

Two architectural extensions to the credential-redaction in the previous
commit:
1. ``/vector_store/update`` had two gaps:
- No per-store access control. Any authenticated principal that
passed the premium-feature gate could mutate *any* vector store,
including stores belonging to other teams.
- The response returned the full DB row including ``litellm_params``,
so the caller could read another team's persisted provider
credentials by submitting a no-op metadata change.
Mirror the access-control check ``/vector_store/info`` already
performs (``_check_vector_store_access`` against the existing row),
redact ``litellm_params`` in the response, and add an
``except HTTPException: raise`` guard so the 403/404 responses don't
get rewritten as 500 by the catch-all.
2. ``SensitiveDataMasker``'s default ``sensitive_patterns`` set used
segment-exact matching, so ``credential`` matched ``vertex_credential``
but not ``vertex_credentials`` (the actual Vertex field name). The
previous commit worked around this with a per-call extension; this
commit puts the plural in the upstream defaults so every caller
(Redis config dump, MCP debug headers, cache routes, ...) gets the
correct behavior. The local override in
``vector_store_endpoints/management_endpoints.py`` is removed.
Also updates ``test_excluded_keys_exact_match`` which relied on
``credentials`` *not* being a sensitive pattern to demonstrate
case-sensitive ``excluded_keys`` matching. The intent of the test
(case-sensitive match) is preserved; the assertion now reflects that
when ``excluded_keys`` fails to apply (wrong case), the field falls
through to standard pattern-based masking instead of being passed
through unchanged.

/simplify pass:
- Remove the single-call-site ``_redact_vector_store`` wrapper. Inline
the two-line redaction at its only caller in ``list_vector_stores``;
``get_vector_store_info`` was already calling the inner helper directly.
- Inherit ``SensitiveDataMasker``'s default sensitive-key set instead of
duplicating the 12-element list, then add only the plural
``credentials`` extension. Won't drift if upstream defaults change.
- Trim the over-explained docstring on ``_redact_sensitive_litellm_params``
to a one-paragraph summary; the WHY (credential-leakage class) belongs
in the commit message, not in every consumer's IDE tooltip.

``LiteLLM_ManagedVectorStore.litellm_params`` carries the upstream provider
credential — OpenAI ``api_key``, AWS ``aws_access_key_id`` /
``aws_secret_access_key``, GCP ``vertex_credentials``, etc. ``GET
/vector_store/list`` and ``POST /vector_store/info`` return these
verbatim to any authenticated principal. Because both routes are in
``openai_routes``, ``RouteChecks.is_llm_api_route`` short-circuits the
standard role gate, so even read-only users and narrowly-scoped keys can
read every stored credential.
Replace credential-bearing values with the ``REDACTED_BY_LITELM``
sentinel in both responses while preserving non-secret keys
(``api_base``, ``region``, ``model``, ``api_version``) so callers can
still see *which* upstream is configured. Detection reuses
``SensitiveDataMasker.is_sensitive_key`` with the default heuristics
plus the plural ``credentials`` pattern (covers Vertex's
``vertex_credentials`` field, which the singular ``credential`` pattern
misses on segment-exact matching).
Applied at:
- ``list_vector_stores`` (``GET /vector_store/list``,
``GET /v1/vector_store/list``)
- ``get_vector_store_info`` (``POST /vector_store/info``), both the
in-memory-registry path and the prisma-DB fallback

CI surfaced two issues from the previous commit:
1. ``general_settings`` and ``master_key`` were still imported at the top
of ``get_logging_payload`` but had no remaining users after the
master-key hash-detection blocks were removed. Drop the import.
2. ``tests/proxy_unit_tests/test_user_api_key_auth.py::test_x_litellm_api_key``
and ``tests/proxy_unit_tests/test_key_generate_prisma.py::test_master_key_hashing``
asserted ``valid_token.token == hash_token(master_key)`` — the
pre-alias behavior. The new contract is
``valid_token.token == LITELLM_PROXY_MASTER_KEY_ALIAS`` (and !=
``hash_token(master_key)``), since the master key (and its hash)
must not propagate to the verification-token column or any other
downstream consumer.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Two related changes to how the master-key auth path interacts with
downstream consumers of UserAPIKeyAuth.api_key:
1. The master-key auth branch in user_api_key_auth.py now sets
`valid_token.api_key` to a stable alias
(`LITELLM_PROXY_MASTER_KEY_ALIAS = "litellm_proxy_master_key"`) instead
of the raw master key. Downstream consumers — spend logging,
Prometheus metrics, audit trails, rate limiting, cost tracking — now
receive the alias instead of the master key (which they would
previously hash and propagate). Neither the raw master key nor its
hash flows past the auth layer.
2. `_is_master_key` in spend_tracking_utils.py is reduced to a strict
raw-only constant-time comparison. The hashed form is no longer
considered equivalent.
Side effects:
- The two hash-detection blocks in `get_logging_payload` are removed.
They were re-detecting the master key per spend-log write to swap in
the alias; that detection happens once at the auth layer now.
- The `disable_adding_master_key_hash_to_db` general setting becomes a
no-op. Operators can remove it from their config; existing config is
still accepted.
- Operator dashboards that filter Prometheus metrics by the master-key

Greptile review on #26756 (P2): if `attempt_db_reconnect` itself raises
(e.g. lock cancellation, timer error, unexpected internal failure), the
original `httpx.ReadError` / transport error was lost — `failure_handler`
and `db_exceptions` alerts then logged the reconnect exception instead of
the actual DB transport problem, masking the root cause.
Wrap the reconnect call in a try/except. On reconnect failure, re-raise
the *original* `first_exc` and chain the reconnect error as `__cause__`
so it remains visible for debuggability without becoming the primary
exception observers see.
Adds `test_call_with_db_reconnect_retry_preserves_original_error_when_reconnect_raises`
asserting (a) the propagated exception is the original transport error
and (b) the reconnect exception is attached as `__cause__`.
Two related fixes layered on top of the existing reconnect plumbing:
1. Restore reconnect-and-retry on `PrismaClient.get_generic_data` (issue
#25143). 1.83.x lost the transport-reconnect-and-retry-once branch that
1.82.6 had on this method, so transient `httpx.ReadError` flaps now
surface immediately as `db_exceptions` alerts. `_update_config_from_db`
fans out four concurrent `get_generic_data` reads, so a single transport
blip used to mark four alerts and a stale config window.
Adds `call_with_db_reconnect_retry` to `litellm/proxy/db/exception_handler.py`
— a single canonical "try DB read, on transport error reconnect once and
retry once" wrapper. Mirrors the inline pattern in
`auth_checks._fetch_key_object_from_db_with_reconnect` so we have one
implementation rather than three drifting copies, and gives future read
paths a clean opt-in.
2. Fix the `_engine_confirmed_dead` flag-reset bug in
`_run_reconnect_cycle`. The flag was cleared before `_do_heavy_reconnect()`
ran, so any failure inside the heavy reconnect (timeout, missing
DATABASE_URL, recreate failure) left the flag False — and the next
attempt could silently demote to the lightweight path even though the
engine was genuinely dead. Move the reset into the success branch so the
flag stays True across heavy-reconnect failures and the next attempt
re-enters the heavy branch.
Tests:
- `tests/test_litellm/proxy/db/test_exception_handler_reconnect_retry.py`
(new) — 9 tests covering the helper's contract: happy path, retry on
transport error, no retry on data-layer errors, propagation when reconnect
fails, propagation after second transport error, `hasattr` guard for
partial mocks, fresh-coroutine-per-call invariant, explicit timeout
override, default timeouts read off the prisma_client.
- `tests/test_litellm/proxy/db/test_prisma_self_heal.py` — adds:
- `test_get_generic_data_retries_on_transport_error_for_config_table`
- `test_get_generic_data_propagates_when_reconnect_fails`
- `test_engine_confirmed_dead_persists_across_failed_heavy_reconnect`
(regression test for the flag-reset bug).
All 16 self-heal tests + 9 helper tests + 535 auth/exception-handler tests
pass locally.
- server.py: drop the redundant server_id append in
_get_filtered_mcp_servers_from_mcp_server_names. iter_known_server_prefixes
already yields server_id unconditionally, so the manual append (and its
misleading comment) was a no-op duplicate.
- utils.py: rewrite the SHORT_MCP_TOOL_PREFIX docstring to accurately
describe the collision behaviour. The previous wording said collisions
were 'cosmetic only', but a natural-hash collision IS a routing-correctness
issue, which is precisely why we already added _assign_unique_short_prefix
to rehash deterministically. The new comment cross-references that path.
- utils.py: restrict the first character of the short prefix to [A-Za-z]
via a 52-char alphabet for position 0 only. The remaining two positions
still use the full base62 alphabet. This keeps prefixes valid identifiers
on every backend and gives 52*62*62 = 199_888 distinct prefixes (still
comfortably more than any realistic deployment).
- tests: add coverage proving the first character of the prefix is always
alphabetic across many server_ids and rehash attempts.
