From 5fcbf91730ea67f8d93f5fb8cc4ee4d1cf927135 Mon Sep 17 00:00:00 2001 From: mateo-berri <277851410+mateo-berri@users.noreply.github.com> Date: Sat, 12 Sep 2026 19:17:26 -0700 Subject: [PATCH 001/106] fix(logging): scan each log record once and collapse base64 payloads before the secret regex Since #37391 every log record went through the secret-redaction regex twice, once in the filter and again in the formatter, and the formatter pass ran on the whole formatted line. At DEBUG level a multi-megabyte request body (a multi-page PDF upload to /v1/ocr) turned each of those lines into ten seconds of synchronous regex work on the event loop, long enough for a Kubernetes liveness probe to restart the pod mid-request. The filter is now the complete scrubber (message, exception text, stack info, and extras) and stamps the record, so the formatters skip records that are already clean. The stdout truncation filter also collapses base64 runs longer than MAX_BASE64_LENGTH_STDOUT_LOG (4096 by default) at every level before the secret regex sees them, so a debug line carrying a request body costs milliseconds instead of seconds. --- litellm/_logging.py | 100 ++++++++--- litellm/constants.py | 1 + litellm/litellm_core_utils/logging_utils.py | 17 +- .../litellm_core_utils/test_logging_utils.py | 10 +- tests/test_litellm/test_logging.py | 165 +++++++++++++++++- tests/test_litellm/test_secret_redaction.py | 6 +- 6 files changed, 249 insertions(+), 50 deletions(-) diff --git a/litellm/_logging.py b/litellm/_logging.py index c73b5175a31..d2c1fe9039d 100644 --- a/litellm/_logging.py +++ b/litellm/_logging.py @@ -1,7 +1,10 @@ import ast import contextvars +import functools +import json import logging import os +import re import sys from datetime import datetime from logging import Formatter @@ -12,6 +15,7 @@ import litellm from litellm.constants import ( LITELLM_TRUNCATED_PAYLOAD_FIELD, LITELLM_TRUNCATION_STDOUT_SAFEGUARD_NOTE, + MAX_BASE64_LENGTH_STDOUT_LOG, MAX_STRING_LENGTH_STDOUT_LOG, ) from litellm.litellm_core_utils.env_utils import get_env_int @@ -76,6 +80,21 @@ def _redact_structured_value(key: str | None, value: str) -> str: return redact_structured_value(key, value) +_REDACTED_RECORD_ATTR: Final = "litellm_redacted" +_UNREDACTED_SCALAR_TYPES: Final = (bool, int, float, type(None)) + + +def _is_redacted(record: logging.LogRecord) -> bool: + return getattr(record, _REDACTED_RECORD_ATTR, False) is True + + +def _redact_extra_value(key: str, value: object) -> object: + try: + return json.loads(safe_dumps({key: value}, value_transform=_redact_structured_value))[key] + except (TypeError, ValueError, KeyError): + return _redact_string(str(value)) + + def redact_secrets(value: str) -> str: """Public API: redact known secret/credential patterns from an arbitrary string. @@ -148,11 +167,19 @@ class SecretRedactionFilter(logging.Filter): except Exception: pass + if isinstance(record.stack_info, str): + record.stack_info = _redact_string(record.stack_info) # rebind-ok: a Filter scrubs records in place + # Redact extra fields passed via logger.debug("msg", extra={...}) for key, value in list(record.__dict__.items()): - if key not in _STANDARD_RECORD_ATTRS and isinstance(value, str): - setattr(record, key, _redact_string(value)) + if key in _STANDARD_RECORD_ATTRS: + continue + if isinstance(value, str): + setattr(record, key, _redact_structured_value(key, value)) + elif not isinstance(value, _UNREDACTED_SCALAR_TYPES): + setattr(record, key, _redact_extra_value(key, value)) + setattr(record, _REDACTED_RECORD_ATTR, True) return True @@ -247,6 +274,37 @@ def _truncate_for_stdout_log(text: str, limit: int) -> str: return f"{text[:head_chars]}{_stdout_truncation_marker(len(text) - kept_chars)}{text[-tail_chars:]}" +_BYTES_PER_KIB: Final = 1024 +_BYTES_PER_MIB: Final = 1024 * 1024 + + +def format_base64_size(num_chars: int) -> str: + """Return a human-readable byte-size estimate from a base64 character count.""" + num_bytes: Final = num_chars * 3 / 4 + if num_bytes >= _BYTES_PER_MIB: + return f"{num_bytes / _BYTES_PER_MIB:.2f}MB" + if num_bytes >= _BYTES_PER_KIB: + return f"{num_bytes / _BYTES_PER_KIB:.1f}KB" + return f"{int(num_bytes)}B" + + +def _get_max_base64_length_stdout_log() -> int: + return get_env_int("MAX_BASE64_LENGTH_STDOUT_LOG", MAX_BASE64_LENGTH_STDOUT_LOG) + + +@functools.lru_cache(maxsize=8) +def _base64_run_pattern(min_chars: int) -> "re.Pattern[str]": + return re.compile(rf"(? str: + return f"[base64_data truncated: {format_base64_size(len(match.group(0)))}]" + + +def _collapse_base64_runs(text: str, limit: int) -> str: + return _base64_run_pattern(limit + 1).sub(_base64_run_placeholder, text) + + class StdoutLogTruncationFilter(logging.Filter): """Bounds how much of an oversized log line reaches stdout. @@ -254,31 +312,31 @@ class StdoutLogTruncationFilter(logging.Filter): request writes hundreds of KB to stdout, repeatedly as the exception propagates from the router to the proxy handler and into its traceback, all inline on the event loop. - DEBUG records pass through untouched, since dumping full payloads is the point of - `--detailed_debug`, and logging callbacks (OTEL, Datadog, etc.) don't run through - logging filters at all, so they still get the untruncated error. + At every level, a base64 run longer than MAX_BASE64_LENGTH_STDOUT_LOG collapses to a + size placeholder first: a multi-megabyte document upload otherwise costs seconds of + event-loop time per DEBUG line in the secret regex alone.

to break the metadata <-> payloads import cycle CodeQL flagged that TraceControls could be undefined when metadata is imported before payloads. trace_controls now depends only on utils, and the mapping / sequence narrowing parses via pydantic TypeAdapter instead of cast.

OCR is the first route on the shared runtime; chat completions, Anthropic messages, and Responses websocket policy checks now read the catalog.

post-call deployment hook on converted chat streams A pre-call deployment hook can turn a requested stream into a non-streaming provider call and the result is wrapped back into a fake stream. The async client wrapper treated that wrapper like a caller-requested stream and returned before async_post_call_success_deployment_hook, so SDK callers lost post-call deployment processing (including CustomGuardrail post_call enforcement) on converted streams. Run the hook on the complete ModelResponse behind the wrapper and rewrap a modified response so it reaches the emitted chunks.

The legacy implementations stay in litellm/main.py, litellm/responses/main.py and the anthropic messages handler, and litellm/__init__.py re-exports the dispatch names over them the same way it already does for ocr The per-handler shims in rust_bridge/chat_completions/native.py and rust_bridge/messages/native.py are removed along with their call sites in the anthropic and bedrock chat handlers and the http handler. The exception mapping that every callbacks module repeated moves to rust_bridge/failures.py and the signature binding helpers to rust_bridge/public_call.py --- litellm/__init__.py | 3 + litellm/chat_completions/__init__.py | 3 + litellm/chat_completions/dispatch.py | 114 +++++ litellm/llms/anthropic/chat/handler.py | 86 +--- litellm/llms/custom_httpx/llm_http_handler.py | 99 ---- litellm/messages/__init__.py | 3 + litellm/messages/dispatch.py | 113 +++++ litellm/responses/dispatch.py | 106 +++++ .../rust_bridge/chat_completions/callbacks.py | 19 + .../chat_completions/entrypoints.py | 54 +++ .../rust_bridge/chat_completions/native.py | 445 ------------------ litellm/rust_bridge/failures.py | 37 ++ litellm/rust_bridge/messages/callbacks.py | 23 + litellm/rust_bridge/messages/entrypoints.py | 54 +++ litellm/rust_bridge/messages/native.py | 136 ------ litellm/rust_bridge/ocr/callbacks.py | 31 +- litellm/rust_bridge/public_call.py | 42 ++ litellm/rust_bridge/responses/callbacks.py | 19 + litellm/rust_bridge/responses/entrypoints.py | 54 +++ tests/e2e/e2e_config.py | 2 - .../test_messages_azure_foundry_e2e.py | 10 +- .../test_rust_bridge_messages.py | 237 ---------- .../test_litellm/chat_completions/__init__.py | 0 .../chat_completions/test_dispatch.py | 186 ++++++++ .../chat/test_anthropic_chat_handler.py | 56 +-- .../chat/test_bedrock_converse_handler.py | 41 +- tests/test_litellm/messages/__init__.py | 0 tests/test_litellm/messages/test_dispatch.py | 198 ++++++++ tests/test_litellm/responses/test_dispatch.py | 195 ++++++++ .../chat_completions/test_callbacks.py | 49 ++ .../chat_completions/test_native.py | 300 ------------ .../rust_bridge/messages/__init__.py | 0 .../rust_bridge/messages/test_callbacks.py | 42 ++ .../rust_bridge/responses/__init__.py | 0 .../rust_bridge/responses/test_callbacks.py | 57 +++ .../test_litellm/rust_bridge/test_failures.py | 54 +++ 36 files changed, 1447 insertions(+), 1421 deletions(-) create mode 100644 litellm/chat_completions/__init__.py create mode 100644 litellm/chat_completions/dispatch.py create mode 100644 litellm/messages/__init__.py create mode 100644 litellm/messages/dispatch.py create mode 100644 litellm/responses/dispatch.py create mode 100644 litellm/rust_bridge/chat_completions/callbacks.py create mode 100644 litellm/rust_bridge/chat_completions/entrypoints.py delete mode 100644 litellm/rust_bridge/chat_completions/native.py create mode 100644 litellm/rust_bridge/failures.py create mode 100644 litellm/rust_bridge/messages/callbacks.py create mode 100644 litellm/rust_bridge/messages/entrypoints.py delete mode 100644 litellm/rust_bridge/messages/native.py create mode 100644 litellm/rust_bridge/public_call.py create mode 100644 litellm/rust_bridge/responses/callbacks.py create mode 100644 litellm/rust_bridge/responses/entrypoints.py delete mode 100644 tests/test_litellm/anthropic_interface/test_rust_bridge_messages.py create mode 100644 tests/test_litellm/chat_completions/__init__.py create mode 100644 tests/test_litellm/chat_completions/test_dispatch.py create mode 100644 tests/test_litellm/messages/__init__.py create mode 100644 tests/test_litellm/messages/test_dispatch.py create mode 100644 tests/test_litellm/responses/test_dispatch.py create mode 100644 tests/test_litellm/rust_bridge/chat_completions/test_callbacks.py delete mode 100644 tests/test_litellm/rust_bridge/chat_completions/test_native.py create mode 100644 tests/test_litellm/rust_bridge/messages/__init__.py create mode 100644 tests/test_litellm/rust_bridge/messages/test_callbacks.py create mode 100644 tests/test_litellm/rust_bridge/responses/__init__.py create mode 100644 tests/test_litellm/rust_bridge/responses/test_callbacks.py create mode 100644 tests/test_litellm/rust_bridge/test_failures.py diff --git a/litellm/__init__.py b/litellm/__init__.py index c6f03172d8e..c80720c3677 100644 --- a/litellm/__init__.py +++ b/litellm/__init__.py @@ -1406,7 +1406,9 @@ from .videos.main import * from .batch_completion.main import * from .rerank_api.main import * from .llms.anthropic.experimental_pass_through.messages.handler import * +from .messages.dispatch import * from .responses.main import * +from .responses.dispatch import * #

2026 15:07:22 -0700 Subject: [PATCH 025/106] fix(logging): keep a log extra only after inspecting every value it holds The filter kept an extra as its original object whenever the plain and scrubbed safe_dumps renderings matched, but safe_dumps skips what it cannot render (non-string dict keys, anything past its depth limit, fields a repr hides), so a secret in those places rode the untouched object past the litellm_redacted stamp. The filter now walks JSON-native shapes itself (strings, scalars, string-keyed dicts, lists and tuples) and keeps the original only when every value it holds comes back unchanged from the redactor; anything else is handed to safe_dumps and the record carries the scrubbed JSON shape the formatter would have rendered --- litellm/_logging.py | 21 ++++++++++-- tests/test_litellm/test_logging.py | 51 +++++++++++++++++++++++++++--- 2 files changed, 65 insertions(+), 7 deletions(-) diff --git a/litellm/_logging.py b/litellm/_logging.py index bcf77d65d96..706ae0c8282 100644 --- a/litellm/_logging.py +++ b/litellm/_logging.py @@ -13,6 +13,7 @@ from urllib.parse import unquote import litellm from litellm.constants import ( + DEFAULT_MAX_RECURSE_DEPTH, LITELLM_TRUNCATED_PAYLOAD_FIELD, LITELLM_TRUNCATION_STDOUT_SAFEGUARD_NOTE, MAX_BASE64_LENGTH_STDOUT_LOG, @@ -88,11 +89,25 @@ def _is_redacted(record: logging.LogRecord) -> bool: return getattr(record, _REDACTED_RECORD_ATTR, False) is True +def _is_secret_free(key: str | None, value: object, depth: int) -> bool: + if depth > DEFAULT_MAX_RECURSE_DEPTH: + return False + if isinstance(value, str): + return _redact_structured_value(key, value) == value + if isinstance(value, _UNREDACTED_SCALAR_TYPES): + return True + if isinstance(value, dict): + return all(isinstance(k, str) and _is_secret_free(k, v, depth + 1) for k, v in value.items()) + if isinstance(value, (list, tuple)): + return all(_is_secret_free(key, item, depth + 1) for item in value) + return False + + def _redact_extra_value(key: str, value: object) -> object: + if _is_secret_free(key, value, 1): + return value try: - rendered: Final = safe_dumps({key: value}) - scrubbed: Final = safe_dumps({key: value}, value_transform=_redact_structured_value) - return value if scrubbed == rendered else json.loads(scrubbed)[key] + return json.loads(safe_dumps({key: value}, value_transform=_redact_structured_value))[key] except (TypeError, ValueError, KeyError): return _redact_string(str(value)) diff --git a/tests/test_litellm/test_logging.py b/tests/test_litellm/test_logging.py index 43be8701b49..884c120f5c9 100644 --- a/tests/test_litellm/test_logging.py +++ b/tests/test_litellm/test_logging.py @@ -1029,17 +1029,23 @@ def test_unserializable_extra_never_breaks_the_filter(monkeypatch, extra): class _RequestExtra: model: str attempt: int + api_key: str = dataclasses.field(default="", repr=False) + + +def _nest(value: object, levels: int) -> object: + return value if levels == 0 else _nest([value], levels - 1) @pytest.mark.parametrize( "extra", ( ("gpt-4o", 2), - {"gpt-4o", "gpt-4o-mini"}, - {"models": ("gpt-4o", "gpt-4o-mini")}, - _RequestExtra(model="gpt-4o", attempt=2), + ["gpt-4o", None, 1.5], + {"models": ("gpt-4o", "gpt-4o-mini"), "attempt": 2}, + {"model": "gpt-4o", "status": "ok"}, + _nest("gpt-4o", 99), ), - ids=("tuple", "set", "nested_tuple", "dataclass"), + ids=("tuple", "list", "nested_tuple", "dict", "deep_list"), ) def test_secret_free_extra_keeps_its_original_object(monkeypatch, extra): """A host application's own handler on a litellm logger reads extras by type, so a @@ -1073,6 +1079,43 @@ def test_extra_that_carried_a_secret_comes_back_scrubbed(monkeypatch, extra): assert "REDACTED" in rendered +@pytest.mark.parametrize( + "extra", + ( + {1: "sk-1234567890abcdefghij"}, + {"model": {1: "sk-1234567890abcdefghij"}}, + _nest("sk-1234567890abcdefghij", 101), + _RequestExtra(model="gpt-4o", attempt=2, api_key="sk-1234567890abcdefghij"), + {"gpt-4o", "sk-1234567890abcdefghij", 1}, + ), + ids=("int_key", "nested_int_key", "deeper_than_safe_dumps", "dataclass_hidden_field", "unsortable_set"), +) +def test_extra_the_filter_cannot_fully_inspect_never_keeps_its_secret(monkeypatch, extra): + """Whatever safe_dumps would skip (non-string keys, anything past its depth limit, + fields a repr hides) must not ride the original object past the redacted stamp.""" + monkeypatch.setattr("litellm._logging._ENABLE_SECRET_REDACTION", True) + record = _make_record(logging.WARNING, "request sent") + record.payload = extra + + assert SecretRedactionFilter().filter(record) is True + rendered = JsonFormatter().format(record) + + assert record.payload is not extra + assert "sk-1234567890abcdefghij" not in str(record.payload) + assert "sk-1234567890abcdefghij" not in rendered + + +def test_secret_free_set_comes_back_as_its_json_shape(monkeypatch): + monkeypatch.setattr("litellm._logging._ENABLE_SECRET_REDACTION", True) + record = _make_record(logging.WARNING, "request sent") + record.payload = {"gpt-4o", "gpt-4o-mini"} + + assert SecretRedactionFilter().filter(record) is True + + assert record.payload == ["gpt-4o", "gpt-4o-mini"] + assert json.loads(JsonFormatter().format(record))["payload"] == ["gpt-4o", "gpt-4o-mini"] + + def test_unscrubbed_record_is_still_redacted_by_the_formatter(monkeypatch): """Records that never met SecretRedactionFilter (uvicorn's, in JSON mode) keep their formatter-side redaction."""

Subject: [PATCH 033/106] fix(spend_tracking): attribute router-rejected requests to the model group provider A request for a configured model group that the router rejects before picking a deployment (all deployments in cooldown, no healthy deployment) never gets a custom_llm_provider in its logging kwargs. The spend log payload persisted an empty provider, the daily spend tables carried it through, and the Admin UI Usage page rendered those requests under unknown even though every model in the group has a provider get_logging_payload now takes the proxy router and, when the logged provider is missing, infers it from the model group's deployments. It only attributes when every deployment in the group resolves to the same provider; mixed groups, unknown groups and a missing router leave the value empty as before.

fix(logging): decide keep-or-scrub for a log extra by comparing it to its scrubbed copy The code-quality check refuses recursive functions and the walk that inspected extras was one, so the filter no longer walks anything itself. safe_dumps now builds its JSON-native structure through safe_json_structure, the filter scrubs the extra through that, and the original object is kept only when the scrubbed copy compares equal to it. Anything the serializer skipped (non-string keys, nests past its depth, fields a repr hides) makes the copy differ, so the copy wins.

budgets for tags added by guardrails Auth runs the tag budget check before pre_call_hook, so a tag that a custom guardrail adds is attributed spend but never budget checked. After the pre-call hook, budget check only the newly added tags with the same exemptions auth applied (budget-free routes, zero-cost models), keep the pre-guardrail tag baseline across fallback retries, and surface an over-budget tag as the same budget_exceeded 429 auth returns Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> ---

Under xdist that names whatever test the serving worker is in, which is unrelated to the caller: the proxy is a separate pod, and the Claude Code compat matrix registered its shared aliases from every worker, each pointing at that worker's edge, so the router spread one worker's calls across all eight edges. Builds 234 and 235 of litellm-e2e, same commit, credited the same Bedrock request to unrelated tests 92% of the time, and Bedrock never converged past a ~20% hit rate while OpenAI, whose deployments are per test, sat at 90%. A deployment registered from inside a test now carries its test's slug in the edge URL it is pointed at, `{edge}/{mount}/t/{slug}`, and the edge reads that segment off every request before forwarding. A request without one is forwarded live and never cached, and the edge no longer falls back to process state. The compat aliases are registered with provider_live=True and stay on their real provider path: no single test owns them, and the matrix exists to prove the real CLI against real providers. --- .../test_provider_cache.py | 152 ++++++++++++++---- tests/e2e/PROVIDER_CACHE.md | 10 +- tests/e2e/claude_code/conftest.py | 5 +- tests/e2e/conftest.py | 3 +- tests/e2e/e2e_config.py | 6 +- tests/e2e/provider_cache.py | 20 ++- tests/e2e/provider_edge.py | 32 ++-- tests/e2e/proxy_client.py | 16 +- tests/e2e/pytest.ini | 2 +- tests/e2e/test_provider_edge.py | 10 +- tests/e2e/test_proxy_client.py | 34 ++++ 11 files changed, 228 insertions(+), 62 deletions(-) diff --git a/tests/code_coverage_tests/test_provider_cache.py b/tests/code_coverage_tests/test_provider_cache.py index e57d33a0406..dda3372c15f 100644 --- a/tests/code_coverage_tests/test_provider_cache.py +++ b/tests/code_coverage_tests/test_provider_cache.py @@ -26,6 +26,7 @@ from e2e_http import NetworkError, PreparedForward, RawResponse, StreamChunk, St from models import LiteLLMParamsBody, ModelMode from botocore.credentials import Credentials from botocore.eventstream import EventStreamBuffer +from fixture_bundle import slug_for_test from provider_cache import ( SIGNATURE_HEADERS, CacheEdge, @@ -35,7 +36,9 @@ from provider_cache import ( ResponseStore, cacheable_endpoint, request_identity, + scoped_edge_base, slotted_key, + split_test_segment, successful_response, ) from provider_cache_redis import PUBLISH, RedisCommands, RedisResponseStore, configured_cache, redis_store @@ -47,7 +50,13 @@ from provider_cache_routing import ( route_cache_model, ) from fixture_mode import SESSION_TEST_KEY -from provider_edge import EDGE_MOUNTS, configured_cache_backend, resolve_mount, start_provider_edge +from provider_edge import ( + EDGE_MOUNTS, + configured_cache_backend, + provider_edge_api_base, + resolve_mount, + start_provider_edge, +) from provider_edge_bedrock import bedrock_signer from redis.exceptions import ConnectionError as RedisConnectionError @@ -57,6 +66,7 @@ SUCCESS: Final = b'{"id":"provider-fixed-id","choices":[{"message":{"content":"h HEADERS: Final = {"content-type": "application/json", "authorization": "Bearer synthetic-account-one"} TEST_KEY: Final = "tests/e2e/synthetic_suite.py::TestCase::test_case" OTHER_TEST_KEY: Final = "tests/e2e/synthetic_suite.py::TestCase::test_other_case" +TEST_SLUG: Final = slug_for_test(TEST_KEY) def marked(marker: str) -> bytes: @@ -173,11 +183,11 @@ def store(redis_url: str) -> RedisResponseStore: return redis_store(redis_url, "test-" + uuid.uuid4().hex) -def cache_edge(store: ResponseStore, test_key: str = TEST_KEY) -> CacheEdge: +def cache_edge(store: ResponseStore) -> CacheEdge: """A cache edge standing in for one pytest process.

A deployment registered from inside a test gets the cache edge's mount URL with a test segment appended, `{edge}/{mount}/t/{slug}`, where the slug is `slug_for_test` of the registering test's node id, and the edge reads that segment off every request before forwarding. The key is a keyed digest over that slug, the method, the upstream URL, the effective outbound headers (including authentication and HTTP-library defaults), body presence and the body bytes, with one normalization: a 12-hex-digit run, the shape `unique_marker()` mints, is replaced by a placeholder in both the URL and a UTF-8 body. Nothing else is normalized away. No prompts, JSON values or credentials are rewritten, and the rule is the one `fixture_canonical.py` already applies for record/replay, so there is a single definition of what a marker is Requests that differ only by their markers therefore share a canonical identity, which is what makes the cache reusable across builds: every e2e test salts its prompt afresh, so an exact-byte key would miss on every call. Within one test, calls that share a canonical identity are still recorded and replayed separately, by a FIFO slot index appended to the key. That matters because a replayed response carries the recorded provider response id, `LiteLLM_SpendLogs.request_id` is that id, and one shared recording answering two calls would collapse two spend rows into one -Two different tests never share a recording, and a provider call made outside any test (fixtures, session setup) is never cached, because the identity has no test node id to bind to +Two different tests never share a recording. A request that reaches the edge without a test segment is forwarded live and never cached, and the edge never names the test from its own process's `PYTEST_CURRENT_TEST`. It used to, and that was wrong whenever the calling test and the serving process differed: the proxy is a separate pod, and under xdist the Claude Code compat matrix registered its shared aliases from every worker, each pointing at that worker's edge, so the router spread one worker's calls across all of them and each call was keyed on whatever test the serving worker was in. Builds 234 and 235 of the e2e pipeline, same commit, credited the same Bedrock request to unrelated tests 92% of the time, which is why that mount never converged -A client that varies its own request between runs defeats that identity without breaking any rule, and the Claude Code compat cells did. The CLI sends a device id and a session id in `metadata.user_id`, and its system prompt names both its memory directory and its working directory, adding the branch and recent commits when that directory is a git repository. Driven with a fresh HOME and the checkout as its working directory, every cell sent different bytes every build. The fix belongs in the driver rather than here: `claude_code/cli_driver.py` pins the config directory, the working directory and both identifiers, which is why the cache needs no rule for any of it. Normalizing them instead would have hidden a real defect class, since a rule cannot tell a client's own churn from a value a test means to assert on +The Claude Code compat cells are not cached. Their aliases are registered once per worker session and shared by every cell, so no call to them belongs to one test, and the matrix exists to prove the real CLI against real providers; `claude_code/conftest.py` registers them with `provider_live=True`. The driver still pins the CLI's config directory, working directory, device id and session id (`_driver_unit_tests/test_request_determinism.py` holds that), so a CLI-driven deployment registered by one test would send stable bytes. Normalizing those values in the key instead would hide a real defect class, since a rule cannot tell a client's own churn from a value a test means to assert on Provider `Set-Cookie` headers are dropped before validation and never recorded: the edge already withholds them from the proxy, and OpenAI responses always carry Cloudflare bot-management cookies @@ -62,4 +62,4 @@ Provider remaining-quota headers describe the captured response.

The scrub now catches every serializer failure and falls back to the object's text, or to the serializer's own "Unserializable Object" marker when even str() raises. JSON mode attaches the filter to uvicorn.error and the other third-party loggers and again to the root handler their records propagate to, so those records paid the secret regex twice. A record already stamped litellm_redacted now passes the filter untouched. --- litellm/_logging.py | 15 ++++++--- litellm/litellm_core_utils/safe_json_dumps.py | 4 ++-

A deployment registered from inside a test gets the cache edge's mount URL with a test segment appended, `{edge}/{mount}/t/{slug}`, where the slug is `slug_for_test` of the registering test's node id, and the edge reads that segment off every request before forwarding. A deployment a module- or class-scoped fixture sets up is owned by that module or class instead: every test in it shares the deployment, `--dist loadfile` keeps those tests in one worker, and the slot index below keeps their calls apart. A session-scoped fixture runs in every worker, so its deployment has no owner and stays live; `driver_models` in `quota_management/spend_tracking/conftest.py` is the main one. The owner is read off the fixture request in `fixture_mode.registration_owner`, never off the process's `PYTEST_CURRENT_TEST`, which during a shared fixture's setup names whichever test happened to ask first. The key is a keyed digest over that slug, the method, the upstream URL, the effective outbound headers (including authentication and HTTP-library defaults), body presence and the body bytes, with one normalization: a 12-hex-digit run, the shape `unique_marker()` mints, is replaced by a placeholder in both the URL and a UTF-8 body. Nothing else is normalized away. No prompts, JSON values or credentials are rewritten, and the rule is the one `fixture_canonical.py` already applies for record/replay, so there is a single definition of what a marker is Requests that differ only by their markers therefore share a canonical identity, which is what makes the cache reusable across builds: every e2e test salts its prompt afresh, so an exact-byte key would miss on every call. Within one test, calls that share a canonical identity are still recorded and replayed separately, by a FIFO slot index appended to the key. That matters because a replayed response carries the recorded provider response id, `LiteLLM_SpendLogs.request_id` is that id, and one shared recording answering two calls would collapse two spend rows into one diff --git a/tests/e2e/conftest.py b/tests/e2e/conftest.py index e17a589af47..e83827fac74 100644 --- a/tests/e2e/conftest.py +++ b/tests/e2e/conftest.py @@ -37,6 +37,7 @@ from e2e_config import ( from e2e_db import RESET_OPT_IN_ENV, reset_spend_logs, run_spend_log_cleanup from e2e_http import unwrap from fixture_mode import fixture_mode_collection_error, fixture_report_lines +from fixture_mode import pytest_fixture_setup as pytest_fixture_setup from idp import Identity, Keycloak, keycloak_from_env from junit_properties import attach_result_properties from lifecycle import ProxyClientProvider, ResourceManager diff --git a/tests/e2e/e2e_config.py b/tests/e2e/e2e_config.py index e228d6c018f..779d8b13e85 100644 --- a/tests/e2e/e2e_config.py +++ b/tests/e2e/e2e_config.py @@ -13,7 +13,7 @@ from pathlib import Path from typing import Final from dotenv import load_dotenv -from fixture_mode import current_test_key, deterministic_marker, parse_fixture_mode +from fixture_mode import deterministic_marker, parse_fixture_mode, registration_owner from provider_edge import provider_edge_api_base # Local runs keep provider / DataDog keys in tests/e2e/.env (see CONTRIBUTING.md). @@ -201,14 +201,16 @@ def provider_edge_base(mount: str) -> str | None: """The api_base an edge-wired deployment should register with, using this process's fixture-mode and edge-host configuration: None in live mode, the shared edge server's mount URL in record and replay, and with the shared - cache on, the cache edge's mount URL scoped to the running test.""" + cache on, the cache edge's mount URL scoped to the node that owns the + deployment: the running test, or the module or class whose fixture is + setting it up.""" return provider_edge_api_base( mount, mode_raw=FIXTURE_MODE_RAW, bundle_dir=FIXTURE_DIR, bind_host=PROVIDER_EDGE_BIND_HOST, advertise_host=PROVIDER_EDGE_ADVERTISE_HOST, - test_key=current_test_key(), + test_key=registration_owner(), forward_timeout=REQUEST_TIMEOUT, ) diff --git a/tests/e2e/fixture_mode.py b/tests/e2e/fixture_mode.py index 9a7c1b6db12..26b315c0c06 100644 --- a/tests/e2e/fixture_mode.py +++ b/tests/e2e/fixture_mode.py @@ -14,11 +14,14 @@ from __future__ import annotations import hashlib import os +from collections.abc import Generator +from contextvars import ContextVar from dataclasses import dataclass from datetime import datetime from pathlib import Path from typing import Final, Literal, assert_never +import pytest from fixture_bundle import ( FreshBundle, StaleBundle, @@ -59,6 +62,31 @@ def current_test_key() -> str: return raw.rsplit(" (", 1)[0] +REGISTRATION_OWNER: Final[ContextVar[str | None]] = ContextVar("registration_owner", default=None) + + +def registration_owner() -> str: + """The pytest node that owns a deployment registered right now.

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.

+0000 Subject: [PATCH 080/106] 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.
