From 1e583e8e79d37e48f8989c08efa08531511b5c95 Mon Sep 17 00:00:00 2001 From: yucheng Date: Mon, 14 Sep 2026 22:31:21 +0000 Subject: [PATCH 01/45] fix(otel v2): map the caller's Langfuse user, session and tags onto the root and generation spans `langfuse_otel` (OTel v2) only carried `trace_name` from the caller's metadata, so `metadata.trace_user_id` / `session_id` / `tags` (and the `langfuse_trace_user_id` / `langfuse_session_id` proxy headers) never reached Langfuse's user, session and tags fields. Widen the typed caller boundary to `TraceControls`, map it through one `LangfuseMapper.trace_attributes` table on both the root observation and the generation span, and keep `team_id` / `team_alias` proxy-authoritative Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> --- litellm/integrations/otel/langfuse_logger.py | 13 ++- litellm/integrations/otel/logger.py | 2 +- litellm/integrations/otel/mappers/langfuse.py | 27 +++++- litellm/integrations/otel/model/metadata.py | 61 ++++++++---- litellm/integrations/otel/model/payloads.py | 7 +- .../integrations/otel/test_langfuse_logger.py | 94 +++++++++++++++++++ .../otel/test_otel_v2_sources_of_truth.py | 61 ++++++++++-- .../otel/test_otel_v2_vendor_mappers.py | 32 ++++++- 8 files changed, 255 insertions(+), 42 deletions(-) diff --git a/litellm/integrations/otel/langfuse_logger.py b/litellm/integrations/otel/langfuse_logger.py index f8fd417392f..177bba0c1e1 100644 --- a/litellm/integrations/otel/langfuse_logger.py +++ b/litellm/integrations/otel/langfuse_logger.py @@ -6,9 +6,9 @@ from litellm.integrations.otel.logger import OpenTelemetryV2 from litellm.integrations.otel.mappers.langfuse import ( LANGFUSE_OBSERVATION_INPUT, LANGFUSE_OBSERVATION_OUTPUT, - LANGFUSE_TRACE_NAME, + LangfuseMapper, ) -from litellm.integrations.otel.model.metadata import caller_trace_name +from litellm.integrations.otel.model.metadata import caller_trace_controls from litellm.integrations.otel.model.request_io import request_input, response_output, stream_output from litellm.integrations.otel.plumbing.context import request_root_span @@ -18,14 +18,13 @@ if TYPE_CHECKING: class LangfuseOpenTelemetryV2(OpenTelemetryV2): - """Names the trace from the request.

the delete test's convergence predicate never settled and the read timed out against a 200 it kept discarding. The predicate now waits for status deleted through the same _key_info_everywhere helper the rest of the file uses, and KeyInfo carries the status field. The chat-rejection assertion after it is unchanged, so the test still proves the key stops serving. --- tests/e2e/management/test_key_lifecycle_e2e.py | 13 ++----------- tests/e2e/models.py | 1 + 2 files changed, 3 insertions(+), 11 deletions(-) diff --git a/tests/e2e/management/test_key_lifecycle_e2e.py b/tests/e2e/management/test_key_lifecycle_e2e.py index 4c8effc4d24..fb153f2a7f3 100644 --- a/tests/e2e/management/test_key_lifecycle_e2e.py +++ b/tests/e2e/management/test_key_lifecycle_e2e.py @@ -22,7 +22,7 @@ from typing import Final import pytest from e2e_config import unique_marker -from e2e_http import Result, StreamingResponse, Success, UnknownApiError, unwrap +from e2e_http import Result, StreamingResponse, Success, unwrap from lifecycle import ResourceManager from management_client import MODEL_ACCESS_DENIED_MARKER, ManagementClient from models import ( @@ -135,10 +135,6 @@ def _key_info_everywhere( return MappingProxyType({replica: unwrap(read).info for replica, read in reads.items()}) -def _is_key_not_found(result: Result[KeyInfoResponse]) -> bool: - return isinstance(result, UnknownApiError) and result.status_code == 404 - - def _assert_reads_back(info: KeyInfo, expected: KeyGenerateBody, replica: str) -> None: for field, observed, wanted in ( ("key_alias", info.key_alias, expected.key_alias), @@ -290,10 +286,5 @@ class TestKeyLifecycle: client.delete_key_strict(created.key) - _ = client.proxy.read_back_everywhere( - "/key/info", - params=KeyInfoParams(key=created.key), - response_type=KeyInfoResponse, - converged=_is_key_not_found, - ) + _ = _key_info_everywhere(client, created.key, lambda info: info.status == "deleted") _assert_chat_rejected_everywhere(client, created.key, mock_deployment) diff --git a/tests/e2e/models.py b/tests/e2e/models.py index 7550bfdc150..9f49c5974d0 100644 --- a/tests/e2e/models.py +++ b/tests/e2e/models.py @@ -136,6 +136,7 @@ class LiteLLMBudgetTable(BaseModel): class KeyInfo(BaseModel): key_alias: str | None = None + status: str | None = None metadata: KeyMetadata | None = None models: list[str] = [] tpm_limit: int | None = None From c6023b4eec898e42e0e3a1c4a3bc51fbfe991041 Mon Sep 17 00:00:00 2001 From: Yuneng Jiang Date: Wed, 16 Sep 2026 20:52:19 -0700 Subject: [PATCH 31/45] test: pin the post-#41289 cooldown contract and scroll the auto-router select spec test_router_fallbacks_with_cooldowns_and_dynamic_credentials expected a caller-supplied credential to register its own deployment and cool it down. #41289 stopped registering it, so cooldown logic skips that id and the assertion can never hold.

+0000 Subject: [PATCH 34/45] fix(guardrails): keep usage chunk and defer tool_calls finish_reason behind held text in incremental_diff A stream_options.include_usage usage chunk (empty delta plus usage) was folded into the final transform round and rebuilt without its usage, so token counts and cost vanished from clients. Metadata-only chunks are now replayed after the final text flush. A terminal tool-call chunk arriving while earlier text was still held back carried finish_reason=tool_calls ahead of that text. The finish_reason is now deferred to the final text chunk whenever the choice has held text.
