From c213234783e87f470b36a63e9d224cdc1d10925a Mon Sep 17 00:00:00 2001 From: "devin-ai-integration[bot]" <158243242+devin-ai-integration[bot]@users.noreply.github.com> Date: Thu, 29 Oct 2026 10:31:18 -0700 Subject: [PATCH 01/13] feat(vertex_ai)!: use HTTP/2 httpx client for search_api vector store (#40631) * feat(vertex_ai): use HTTP/2 httpx client for search_api vector store Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> * test(httpx): exercise configured request path Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> * test(httpx): verify HTTP/2 request negotiation Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> * fix(httpx): preserve HTTP/2 for sync proxy mounts Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> * build(deps): add h2 to proxy extra so vertex search HTTP/2 is on by default Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> * fix(http_handler): isolate ssl context for http2 clients Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> * fix(http): add an HTTP/2 opt-out and harden the Vertex AI Search HTTP/2 client litellm.http2 is now unset by default, so http2: false or LITELLM_HTTP2=False turns the provider's HTTP/2 default off. A caller's own SSLContext keeps the search on HTTP/1.1, the HTTP/2 async client honors DISABLE_AIOHTTP_TRUST_ENV, forced IPv4 transports get the CA bundle and client cert, and vector store search retries once when the server drops the connection with a GOAWAY. * fix(http): retry vector store search only on HTTP/2 GOAWAY and keep aiohttp pool and proxy behavior Scope the one retry to a connection Google closes with an HTTP/2 GOAWAY and log it. When HTTP/2 replaces the aiohttp transport, keep aiohttp's idle keepalive and connection cap, and only then skip env proxies under DISABLE_AIOHTTP_TRUST_ENV, so the global LITELLM_HTTP2 toggle keeps HTTPS_PROXY * test(http): cover the vector store search GOAWAY retry in unit tests and drop duplicate SSL cache comments * fix(http): open another HTTP/2 connection once 100 streams are in use httpcore keeps every request to an origin on one HTTP/2 connection and caps it at 100 concurrent streams, so request 101 and later waited with no timeout. The handlers now spread requests over extra connections, opening one only when every open connection has 100 streams in flight. The force_ipv4 wire tests now cover ssl_verify=False and the client certificate. * fix(vertex_ai): reuse one Vertex search OAuth token across searches Every vector store search built a new search config, so the token cache it carries was thrown away and each search fetched a new Google OAuth token with a blocking call on the event loop. Under a burst of searches that blocking fetch held back every HTTP/2 response. The provider config is now shared, so searches with the same credentials reuse one token until it expires. * fix(http): keep the HTTP/2 connection spread within the connection cap * fix(http): keep sync vertex search on HTTP/1.1, since httpcore's sync HTTP/2 is not thread-safe httpcore 1.0.9 hands two threads the same HTTP/2 stream id, so threaded sync searches failed with protocol errors. Only the async client, which the proxy uses, now defaults to HTTP/2, and the sync connection spread is removed. * fix(http): split the connection cap across HTTP/2 lanes Each lane had its own pool with the full connection cap, so an origin answering HTTP/1.1, or several origins on one client, could exceed max_connections once more than 100 requests were in flight. Lanes now open only while lanes times 100 streams stay under the cap, and each lane pool gets at most 100 of it. * test(http2): scope wire-test peer logs to each fixture instance * fix(http2): keep TE, force_ipv4 trust, evicted-client and opt-out behavior on the HTTP/2 path - drop TE values other than trailers on https requests through the HTTP/2 spread, since h2 refuses them - force_ipv4 transports keep httpx's default trust store (SSL_CERT_DIR) unless SSL is configured - the evicted client closer asks the HTTP/2 spread whether a request is in flight - LITELLM_HTTP2 set to 0, no or off, and a quoted "false" http2 setting, opt out of HTTP/2 - the wire test's held-search barrier waits on an event instead of polling * fix(http2): count proxy-mounted transports when checking an evicted client for in-flight requests * test(http2): move the HTTP/2 eviction cases that open a loopback server into the integration wire tests * fix(http2): read an unquoted http2: 0 as off and free the stream slot of a response dropped without closing * fix(http2): free the stream slot of a partly read response dropped without closing * test(http2): check that the evicted client and its stream close after a partly read response is dropped --------- Co-authored-by: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> Co-authored-by: mrinal Co-authored-by: mateo-berri <277851410+mateo-berri@users.noreply.github.com> --- litellm/__init__.py | 2 +- litellm/caching/evicted_client_closer.py | 39 +- .../base_llm/vector_store/transformation.py | 3 + .../custom_httpx/http2_connection_spread.py | 128 ++++ litellm/llms/custom_httpx/http_handler.py | 166 ++++- litellm/llms/custom_httpx/llm_http_handler.py | 48 +- .../search_api/transformation.py | 6 + litellm/utils.py | 4 +- tests/integration/sdk/test_http2_wire.py | 640 +++++++++++++++++- .../test_http2_connection_spread.py | 264 ++++++++ .../llms/custom_httpx/test_http_handler.py | 4 +- .../custom_httpx/test_llm_http_handler.py | 53 ++ 12 files changed, 1278 insertions(+), 79 deletions(-) create mode 100644 litellm/llms/custom_httpx/http2_connection_spread.py create mode 100644 tests/unit/llms/custom_httpx/test_http2_connection_spread.py diff --git a/litellm/__init__.py b/litellm/__init__.py index a1bda4aa9f7..3e8cddac12c 100644 --- a/litellm/__init__.py +++ b/litellm/__init__.py @@ -520,7 +520,7 @@ aiohttp_trust_env: bool = False # set to true to use HTTP_ Proxy settings disable_aiohttp_transport: bool = False # Set this to true to use httpx instead disable_aiohttp_trust_env: bool = False # When False, aiohttp will respect HTTP(S)_PROXY env vars force_ipv4: bool = False # when True, litellm will force ipv4 for all LLM requests.

Read it as a Mapping so an operator who sets drop_params, true or false, keeps the decision on /v1/messages, chat, and count_tokens * fix(proxy): keep the Claude Code and Codex drop_params default unless the admin's value reads as false A drop_params: true saved through /config/update never reaches the global setting, so treating the key's presence as an opt-out made Claude Code and Codex requests answer 400 there. Only a value that reads as false now turns the default off; true, empty, or missing keeps it. * test(proxy): cover string drop_params values in the Claude Code and Codex default rows Adds rows for "false", " False ", "true" and an unreadable "maybe" under litellm_settings, so swapping the value check for a plain is-not-False comparison fails the suite * docs(proxy): say only a false operator drop_params turns off the agentic CLI default --------- Co-authored-by: mateo-berri <277851410+mateo-berri@users.noreply.github.com> --- litellm/proxy/litellm_pre_call_utils.py | 13 +++--- .../anthropic_endpoints/test_endpoints.py | 26 +++++++++++ .../unit/proxy/test_litellm_pre_call_utils.py | 44 ++++++++++--------- 3 files changed, 56 insertions(+), 27 deletions(-) diff --git a/litellm/proxy/litellm_pre_call_utils.py b/litellm/proxy/litellm_pre_call_utils.py index 0f8ca36349c..8f60311e491 100644 --- a/litellm/proxy/litellm_pre_call_utils.py +++ b/litellm/proxy/litellm_pre_call_utils.py @@ -49,7 +49,7 @@ from litellm.constants import ( X_LITELLM_DISABLE_CALLBACKS, ) from litellm.integrations.custom_guardrail import without_server_streaming_classification -from litellm.litellm_core_utils.core_helpers import is_codex_user_agent +from litellm.litellm_core_utils.core_helpers import is_codex_user_agent, normalize_drop_params from litellm.litellm_core_utils.credential_accessor import CredentialAccessor from litellm.litellm_core_utils.initialize_dynamic_callback_params import ( TRUSTED_CALLBACK_VARS_FIELD, @@ -1102,18 +1102,17 @@ def should_auto_drop_params_for_agentic_cli( ) -> bool: """drop_params defaults to on for agentic CLIs so their client-specific params (e.g. Claude Code's thinking, Codex's service_tier) don't fail - requests routed to providers that reject them.

response cost once for header, spend log and rollups (#48993) * fix(cost): finalize synchronous response cost before accounting callbacks * fix(cost): keep serving and billing when cost finalization fails Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> * fix(cost): read the finalized cost only off real logging objects Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> * test(guardrails): follow the renamed success dispatch and deferred sync callbacks Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> * fix(cost): keep cache hits free and their headers finalized when logging is deferred Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> * fix(cost): preserve completed synchronous charges after hook failures * fix(cost): retain completed usage across cancellation and log suppression * fix(cost): reconcile completed failures and retain cached usage metadata * fix(cost): retain finalized request tags in failure budget updates * fix(cost): honor disabled spend tracking for completed failures * fix(cost): preserve pass-through accounting across cancellation --------- Co-authored-by: Joshua Valluru <326636767+joshua-berri@users.noreply.github.com> Co-authored-by:

Key and team destinations were then served by a generic v2 logger without the Langfuse mapper, so their traces lost tags, user and cost, and the legacy logger added an orphaned raw_gen_ai_request span. The preset now always degrades to the credential-gated exporter when the operator has no keys, the same way arize_preset does, so the startup logger stays on v2, exports nowhere for traffic without a destination, and carries the Langfuse mapper to every key and team destination. * test(otel): type the langfuse tenant-only test helpers * fix(otel): give key/team Langfuse destinations the Langfuse fields when langfuse_otel is not a callback With langfuse_otel only in a key's or team's logging, the startup logger is the generic one and its spans reached the key's Langfuse project without user, session or tags. The emitter now adds the Langfuse mapper for a request with a Langfuse destination, and every non-Langfuse exporter strips the Langfuse request metadata, since any logger can now write it. * fix(otel): stop a key's Langfuse logger from re-sending spans to the operator's collector With langfuse_otel only in key or team logging, the proxy publishes the generic V2 logger at startup and it already exports to the operator's OTLP collector. The Langfuse logger a key's request builds kept the same base exporter, so the collector got every model span twice. A logger built after the publish now keeps only its preset's own exporters, as it already did beside a configured V2 logger, and a later call that would rebuild one exporting nowhere reuses it. * test(otel): assert the collector gets one copy instead of reading the key logger's exporters * test(otel): count the collector's spans with one comprehension clause * fix(otel): keep the legacy langfuse_otel logger and stand it down for requests a Langfuse destination carries Reverts the preset degrade and the published-provider exporter trim, so every request without a key or team Langfuse destination keeps main's legacy logger. For a request with one, the V2 fan-out already delivers the whole trace with the Langfuse fields, so the legacy logger emits nothing for it. * test(otel): pin the legacy langfuse_otel paths a tenant's project still gets without a destination * fix(otel): shed a destination's Langfuse request metadata before its other Langfuse fields At its attribute limit a span sheds the Langfuse fields only a destination asked for first, in the mapper's order, so the generation marker went before the request metadata blob. Put the request metadata first, as a Langfuse-configured logger already does. * fix(otel): keep the legacy langfuse_otel span for a destination's call rejected before any provider The OTel v2 fan-out records no call for a request the proxy rejects before a provider (rate limit, pre-call hook), so standing the legacy logger down there lost the user, session and tags main sent the tenant.

yucheng-berri Date: Thu, 29 Oct 2026 12:19:39 -0700 Subject: [PATCH 10/13] feat(guardrails): scan sampled stream windows in the background (#48952) * feat(guardrails): scan sampled stream windows in the background (LIT-9338) streaming_scan_in_background runs each sampled post_call scan as a task so the stream keeps flowing; a block ends the stream before the next chunk. * fix(guardrails): hold the stream end for the background verdict and cancel the scan on upstream errors (LIT-9338) * fix(guardrails): wait for the cancelled background scan on upstream errors (LIT-9338) * test(guardrails): cover /v1/responses, a failing scan peer and a mixed burst for background scans (LIT-9338) * test(guardrails): build the burst calls without a nested comprehension (LIT-9338) ---

From ffcc4f7a70148df3905b6b064857c32b17d3ea71 Mon Sep 17 00:00:00 2001 From: yucheng-berri Date: Thu, 29 Oct 2026 12:20:07 -0700 Subject: [PATCH 11/13] fix(otel)!: print OTel v2 spans to stdout only when the operator asks (#48723) * fix(otel): stop OTel v2 vendor presets from printing every span to stdout With LITELLM_OTEL_V2 on and a vendor callback such as langfuse_otel or arize holding operator credentials, the proxy printed every span as JSON to stdout, prompts included, on the request path. Nobody set OTEL_EXPORTER, but the console placeholder that OpenTelemetryV2Config folds in for an empty exporter list stayed next to the vendor's own exporter. The provider now skips that placeholder when the config has any other exporter. A console exporter the operator names with OTEL_EXPORTER=console is kept, and so is the placeholder when it is the only exporter. * test(otel): type the console-placeholder tests and drop inherited OTEL_* env from the stdout check * fix(otel): print the console default only for the otel callback The proxy's background V2 logger (published when no callback built one, which is what key-only and team-only Langfuse destinations run under) also kept the unconfigured console exporter, so it printed every span with prompts to stdout. The console default now prints only for a listed otel callback or an exporter the operator named. * fix(otel): keep the otel callback's console output on service-name routes A key or team otel_service_name moves the call onto a provider the tenant tracer cache builds, which never got the console choice, so the plain otel callback stopped printing those calls. The no-operator-keys integration rig also drops inherited Langfuse keys. --- litellm/integrations/otel/logger.py | 9 +- litellm/integrations/otel/model/config.py | 11 ++ .../integrations/otel/plumbing/providers.py | 8 ++ litellm/integrations/otel/plumbing/routing.py | 3 + litellm/integrations/otel/presets/utils.py | 13 +- litellm/litellm_core_utils/litellm_logging.py | 2 +- .../_langfuse_otel_metadata_support.py | 14 ++- .../test_langfuse_otel_console_output.py | 98 +++++++++++++++ .../otel/test_otel_v2_destinations.py | 115 +++++++++++++++++- 9 files changed, 252 insertions(+), 21 deletions(-) create mode 100644 tests/integration/observability/test_langfuse_otel_console_output.py diff --git a/litellm/integrations/otel/logger.py b/litellm/integrations/otel/logger.py index 4c9618800ab..b5b65d299e0 100644 --- a/litellm/integrations/otel/logger.py +++ b/litellm/integrations/otel/logger.py @@ -198,6 +198,7 @@ class OpenTelemetryV2(CustomLogger): tracer_provider: TracerProvider | None = None, logger_provider: LoggerProvider | None = None, meter_provider: "MeterProvider | None" = None, + console_default: bool = False, **kwargs: Unpack[_CustomLoggerOptions], ) -> None: super().__init__(**kwargs) @@ -206,7 +207,7 @@ class OpenTelemetryV2(CustomLogger): self._tracer_provider: TracerProvider = ( tracer_provider if tracer_provider is not None - else build_tracer_provider(self.config, tenant_overrides=True) + else build_tracer_provider(self.config, tenant_overrides=True, console_default=console_default) ) self.tracer: Tracer = get_tracer(self._tracer_provider, LITELLM_TRACER_NAME) self._metrics_recorder = self._init_metrics(meter_provider) @@ -217,7 +218,9 @@ class OpenTelemetryV2(CustomLogger): mappers=resolve_mappers(self.config.mapper_names), event_recorder=self._init_events(logger_provider), ) - self._tenant_tracers = TenantTracerCache(self.config, callback_name, LITELLM_TRACER_NAME) + self._tenant_tracers = TenantTracerCache( + self.config, callback_name, LITELLM_TRACER_NAME, console_default=console_default + ) self._open_llm_calls: OrderedDict[str, _LLMCallSpan] = OrderedDict() self._init_otel_logger_on_litellm_proxy() @@ -1089,6 +1092,7 @@ def build_otel_v2_logger( logger_provider: LoggerProvider | None = None, meter_provider: "MeterProvider | None" = None, settings: Mapping[str, object] = MappingProxyType({}), + console_default: bool = False, ) -> OpenTelemetryV2: return _logger_class(config)( config=config, @@ -1096,6 +1100,7 @@ def build_otel_v2_logger( tracer_provider=tracer_provider, logger_provider=logger_provider, meter_provider=meter_provider, + console_default=console_default, **settings, ) diff --git a/litellm/integrations/otel/model/config.py b/litellm/integrations/otel/model/config.py index dd150082252..b50e927f977 100644 --- a/litellm/integrations/otel/model/config.py +++ b/litellm/integrations/otel/model/config.py @@ -121,6 +121,17 @@ class ExporterSpec(LiteLLMBaseModel): ) +def is_unconfigured_placeholder(spec: ExporterSpec) -> bool: + """Whether ``spec`` is the one ``_normalize`` folds in when nothing was configured. + + No field set is what says the operator asked for nothing: an exporter they did + configure survives, even ``OTEL_EXPORTER=console`` whose value matches the default, + and so does the gated spec ``credential_gated_exporters`` appends, which would + otherwise eat itself when one preset layers onto another. + """ + return not spec.model_fields_set + + class _EnvWithoutBareExcludedServices(PydanticBaseSettingsSource): def __init__(self, settings_cls: type[BaseSettings], env_settings: PydanticBaseSettingsSource) -> None: super().__init__(settings_cls) diff --git a/litellm/integrations/otel/plumbing/providers.py b/litellm/integrations/otel/plumbing/providers.py index 39e78194228..b5a5b85fc11 100644 --- a/litellm/integrations/otel/plumbing/providers.py +++ b/litellm/integrations/otel/plumbing/providers.py @@ -56,6 +56,7 @@ from litellm.integrations.otel.model.config import ( OpenTelemetryV2Config, capture_message_content_from_env, captures_span_content, + is_unconfigured_placeholder, ) from litellm.integrations.otel.model.semconv import ( DB, @@ -1551,6 +1552,7 @@ def build_tracer_provider( use_simple_processor: bool | None = None, tenant_overrides: bool = False, strip_message_content: bool = False, + console_default: bool = False, ) -> TracerProvider: """Build the shared :class:`TracerProvider`. @@ -1575,6 +1577,10 @@ def build_tracer_provider( ``strip_message_content`` removes prompt and response content before every exporter, for a routed provider whose spans can carry content another destination asked for. + + The console spec ``config._normalize`` folds in when nothing was configured + prints only under ``console_default``, which the ``otel`` callback passes: a + vendor preset or the proxy's background global logger was never asked to print.

From 62b8ee78de5eccca5b5a34383e59a430dccd0629 Mon Sep 17 00:00:00 2001 From: yuneng-jiang Date: Thu, 29 Oct 2026 12:50:08 -0700 Subject: [PATCH 12/13] ci: run the integration groups on GitHub Actions (#48985) * test: add a manually dispatched integration trial on larger runners Runs the providers, database and management integration groups on 16-core GitHub-hosted runners with Postgres and Redis as service containers, to measure wall time and how far each group scales with more workers run_integration.sh now keeps a preset INTEGRATION_WORKERS, takes the service container names from the environment, and seeds test order from the GitHub run when there is no CircleCI one * test: run the integration trial on push to this branch * test: give integration trial workers a local redis-server * test: run the providers trial on a 64-core runner with 32 workers The 16-core run reached 53% of providers in 45 minutes with 16 workers, which points at CPU. Postgres gets max_connections=1000 and a 1 GB shm because one server now backs 32 worker proxies, where each CircleCI machine backs 4 * test: run every integration group in the trial on sized runners * test: add a scan that refuses to upload integration results holding the license * test: drop the member-name pass the archive byte scan already covers * test: use a secret whose base64 and base64url encodings differ * ci: run integration groups on run-ci pull requests and scheduled main runs * ci: scope the integration license to a protected environment --- .circleci/scripts/run_integration.sh | 21 +-- .github/scripts/assert_secret_absent.py | 119 ++++++++++++++ .github/workflows/test-integration.yml | 199 ++++++++++++++++++++++++ tests/integration/AGENTS.md | 7 +- tests/integration/README.md | 2 +- tests/unit/test_assert_secret_absent.py | 124 +++++++++++++++ 6 files changed, 460 insertions(+), 12 deletions(-) create mode 100644 .github/scripts/assert_secret_absent.py create mode 100644 .github/workflows/test-integration.yml create mode 100644 tests/unit/test_assert_secret_absent.py diff --git a/.circleci/scripts/run_integration.sh b/.circleci/scripts/run_integration.sh index 00b3c5f8fdd..1380b07de53 100644 --- a/.circleci/scripts/run_integration.sh +++ b/.circleci/scripts/run_integration.sh @@ -1,14 +1,14 @@ #!/usr/bin/env bash set -euo pipefail -if [ "${GITHUB_ACTIONS:-}" = true ]; then -
