How well each model performs, by request type

+
+ Each bar shows the fraction of recent feedback that was positive + for that model on that kind of request. Wider = better. The number + next to it ("N signals") is how much real feedback the bar is + based on — more signals means the router is more confident. + It picks higher-quality bars first, with cost as a tiebreaker. +

Previously the documented header was defined but never extracted, so the quality-floor feature was inert. - Evict expired entries from _session_states. The cache grew without bound — added a parallel expiry map (same TTL as _owner_cache) and an opportunistic bulk sweep when the cache crosses a size threshold. - Align adaptive-router migration SQL with Prisma schema: all count columns and the 'clean_credit_awarded' / 'last_processed_turn' fields are NOT NULL in the data model, so the migration now declares them NOT NULL. Fixes test_aaaasschema_migration_check. Tests: 8 new covering header/metadata/precedence/invalid-value paths for min_quality_tier and TTL-based eviction of _session_states.

charset=UTF-8 Content-Transfer-Encoding: 8bit The post-call hook was hardcoding tool_results=[] on every Turn, so the failure detector never saw tool errors and the bandit only learned from satisfaction — never from negative tool outcomes. Added _recent_tool_results(messages): walks the request messages from the tail and collects the contiguous run of role=='tool' entries — those are the results from the most recent assistant tool_calls round. Normalizes each to {content, is_error}, the only fields signals._detect_failure / _detect_exhaustion read. Tests: 6 new covering empty input, trailing-run extraction, is_error propagation, boundary at first non-tool message, no-trailing-tool case, and the end-to-end path from hook -> Turn.tool_results.

Updated: - test_resolve_session_key_* (4 tests): _resolve_session_key now requires at least SIGNAL_GATE_MIN_MESSAGES messages before deriving a hash (it returns None on shorter convos to match the signal-processing gate). Switched the tests to use _long_messages() so they hit the hash path. - test_post_call_success_hook_* (2 tests): the hook was migrated from async_post_call_success_hook (mutates response._hidden_params) to async_post_call_response_headers_hook (returns a headers dict) because the former fires too late for streaming responses. Rewrote the tests against the new API; added a metadata-not-dict noop case.

The proxy continued serving whatever bundle was checked in, so every e2e_ui_testing run between this job's introduction (d09d98a70a, 2026-04-08) and the bundle-rebuild commit (de790fd273, 2026-04-18) was effectively testing a STALE bundle — not the fresh build. That is why the double-prefix regression (NEXT_PUBLIC_BASE_URL="ui/" combined with networking.tsx reading the env var) was never caught in CI even though the source contained the trigger the whole time: the bundle the proxy served never picked up the source change. Replace cp -r with rm + mv so the destination is cleanly swapped. Verified end-to-end on an Ubuntu 22.04 / GNU coreutils 8.32 container: - Before fix: fresh build has 9 "ui/" literals in chunks; after cp, _experimental/out/* still has 0 (stale); _experimental/out/out/ is a nested dir the proxy does not serve. - After fix: _experimental/out/* has 9 "ui/" literals — the proxy now serves the freshly built (broken, in this repro) bundle, so globalSetup fails at login and every spec is blocked. Removing the bug from .env.production and rebuilding brings the count back to 0 and the suite passes. No spec changes, no fixtures, no new infrastructure. The existing Playwright suite already catches this class of regression via the login flow in globalSetup; it just needs the CI to actually hand it the freshly built bundle. --- .circleci/config.yml | 11 ++++++++++- 1 file changed, 10 insertions(+), 1 deletion(-) diff --git a/.circleci/config.yml b/.circleci/config.yml index 9b976462b13..8c75bdc5f33 100644 --- a/.circleci/config.yml +++ b/.circleci/config.yml @@ -3051,10 +3051,19 @@ jobs: - ui/litellm-dashboard/node_modules - run: name: Build UI from source + # Prior version used `cp -r out/ ../../litellm/proxy/_experimental/out/`. + # GNU cp (used on CircleCI's Ubuntu image) interprets that as "copy the + # source directory as a child of the destination" when the destination + # already exists — silently creating `_experimental/out/out/` instead of + # replacing the served bundle.

Root cause: image_edit_handler and async_image_edit_handler did not pass litellm_params to validate_environment, unlike image_generation_handler. Fixes: 1. Widen BaseImageEditConfig.validate_environment signature to accept litellm_params and api_base (optional kwargs). 2. Forward dict(litellm_params) and litellm_params.api_base from both sync and async image_edit handlers to validate_environment. 3. Update VertexAIImagenImageEditConfig.validate_environment to read vertex_ai_project/vertex_ai_credentials from litellm_params first, matching Gemini config pattern (secondary latent bug fix). 4. Widen all image-edit config override signatures to match base.

Top-level body fields are filtered to a typed allowlist. New `BedrockInvokeAnthropicMessagesRequest` TypedDict (in `litellm/types/llms/bedrock.py`) captures the Bedrock Invoke Anthropic Messages body schema; the runtime allowlist is derived from its `__annotations__` so the type and the filter can't drift. Anchored to the AWS reference page in docstrings + transform comment. An exact-set test pins the resolved allowlist so any future edit forces conscious review. Drops context_management, output_config, speed, mcp_servers, container, inference_geo, internal litellm_metadata, and any future Anthropic addition. output_format stays as an active inline-schema conversion (not just a strip). 2. The anthropic-beta header list is filtered + transformed against the bedrock mapping for ALL betas, not just auto-injected ones. The previous code union'd user-provided betas back in unfiltered, so a client on a new Anthropic-direct beta (e.g. advisor-tool-…, context-management-…) could still pin the request to fail. In a proxy context the client can't know the backend is Bedrock; the provider mapping is authoritative. User-provided drops are logged at WARNING so intentional overrides leave a breadcrumb. Updates one existing test that happened to assert on the old buggy pass-through (it used output-128k-2025-02-19, which is null in the bedrock mapping and would 400 at runtime); rewrote it against a bedrock-supported beta. Scope: messages/invoke only. The same user-beta bypass exists in chat/invoke but that's a different code path with different user-expectation trade-offs — follow-up. --- .../anthropic_claude3_transformation.py | 46 +++++- litellm/types/llms/bedrock.py | 44 ++++++ .../test_anthropic_claude3_transformation.py | 149 ++++++++++++++++++ .../bedrock/test_anthropic_beta_support.py | 4 +- 4 files changed, 233 insertions(+), 10 deletions(-) diff --git a/litellm/llms/bedrock/messages/invoke_transformations/anthropic_claude3_transformation.py b/litellm/llms/bedrock/messages/invoke_transformations/anthropic_claude3_transformation.py index 31e0e76fd9f..96593b35d0c 100644 --- a/litellm/llms/bedrock/messages/invoke_transformations/anthropic_claude3_transformation.py +++ b/litellm/llms/bedrock/messages/invoke_transformations/anthropic_claude3_transformation.py @@ -34,6 +34,7 @@ from litellm.llms.bedrock.common_utils import ( remove_custom_field_from_tools, ) from litellm.types.llms.anthropic import ANTHROPIC_TOOL_SEARCH_BETA_HEADER +from litellm.types.llms.bedrock import BedrockInvokeAnthropicMessagesRequest from litellm.types.llms.openai import AllMessageValues from litellm.types.router import GenericLiteLLMParams from litellm.types.utils import GenericStreamingChunk @@ -59,6 +60,10 @@ class AmazonAnthropicClaudeMessagesConfig( DEFAULT_BEDROCK_ANTHROPIC_API_VERSION = "bedrock-2023-05-31" + BEDROCK_INVOKE_ALLOWED_TOP_LEVEL_FIELDS = frozenset( + BedrockInvokeAnthropicMessagesRequest.__annotations__.keys() + ) + def __init__(self, **kwargs): BaseAnthropicMessagesConfig.__init__(self, **kwargs) AmazonInvokeConfig.__init__(self, **kwargs) @@ -500,10 +505,6 @@ class AmazonAnthropicClaudeMessagesConfig( anthropic_messages_request=anthropic_messages_request, ) - # 5b.

Adds two guards to ci_cd/run_migration.py: - Branch freshness check: fetches origin/ and exits 3 if HEAD is behind. Default base is litellm_internal_staging. New flags: --base-branch, --skip-freshness-check. - Destructive guard: refuses (exit 2) if the generated diff contains DROP COLUMN / DROP TABLE / DROP INDEX, unless --allow-destructive is passed. Refusal banners include guidance and an explicit callout instructing AI agents not to auto-bypass the flags. Also treats Prisma's "-- This is an empty migration." output as a no-op rather than writing an empty file.

Users who have seen schema thrashing during rolling deploys can opt into the v2 resolver with `--use_v2_migration_resolver`. Why v2 is safer: - Runs `prisma migrate deploy` only. - Recovers from P3005 (baseline) and idempotent P3009/P3018 errors, same as v1. - Never calls `_resolve_all_migrations`, which generates a schema diff between the live DB and the shipped schema.prisma and applies it via `prisma db execute`. That path bypassed every migration's SQL and was the root cause of thrashing when two LiteLLM versions contended for the same DB. - Logs a non-blocking warning when the DB has migrations applied that are newer than anything this build ships (ahead-of-HEAD). It does not refuse to start — many users have unusual ledger state from past thrashing, and blocking startup would be a breaking change. Also prints a message on startup when the default (v1) resolver is in use, pointing operators at the opt-in flag. Adds unit tests covering the v2 fail-fast paths, the stripping of Prisma-specific query params from DATABASE_URL (needed for psycopg), the timestamp helpers, and pins the default: v1 still invokes `_resolve_all_migrations`, v2 must not. --- .../litellm_proxy_extras/utils.py | 263 +++++++++++++++++- .../tests/test_setup_database_fail_fast.py | 158 +++++++++++ litellm/proxy/db/prisma_client.py | 15 +- litellm/proxy/proxy_cli.py | 39 ++- 4 files changed, 467 insertions(+), 8 deletions(-) create mode 100644 litellm-proxy-extras/tests/test_setup_database_fail_fast.py diff --git a/litellm-proxy-extras/litellm_proxy_extras/utils.py b/litellm-proxy-extras/litellm_proxy_extras/utils.py index c24188cba1d..04005ce2548 100644 --- a/litellm-proxy-extras/litellm_proxy_extras/utils.py +++ b/litellm-proxy-extras/litellm_proxy_extras/utils.py @@ -30,6 +30,26 @@ def _get_prisma_env() -> dict: return prisma_env +_MIGRATION_TS_RE = re.compile(r"^(\d{14})_") + + +def _migration_timestamp(name: str) -> int: + """Extract the leading `YYYYMMDDHHMMSS` timestamp from a migration name. + + Returns 0 if the name doesn't match the Prisma pattern — unexpected-format + entries sort as "oldest" and are treated as historical. + """ + m = _MIGRATION_TS_RE.match(name) + return int(m.group(1)) if m else 0 + + +def _max_migration_timestamp(names) -> int: + """Max timestamp in a set/list of migration names (0 if empty).""" + if not names: + return 0 + return max(_migration_timestamp(n) for n in names) + + def _get_prisma_command() -> str: """Get the Prisma command to use, bypassing Python wrapper in offline mode.""" if str_to_bool(os.getenv("PRISMA_OFFLINE_MODE")): @@ -383,18 +403,255 @@ class ProxyExtrasDBManager: ) @staticmethod - def setup_database(use_migrate: bool = False) -> bool: + def _strip_prisma_query_params(url: str) -> str: + """Remove Prisma-specific query params (connection_limit, pool_timeout, + schema, etc.) from DATABASE_URL so psycopg can parse it.""" + from urllib.parse import urlparse, urlunparse, parse_qsl, urlencode + + parsed = urlparse(url) + if not parsed.query: + return url + libpq_params = { + "sslmode", + "sslcert", + "sslkey", + "sslrootcert", + "sslpassword", + "application_name", + "connect_timeout", + "client_encoding", + "options", + "service", + "gssencmode", + "krbsrvname", + "target_session_attrs", + } + kept = [(k, v) for k, v in parse_qsl(parsed.query) if k in libpq_params] + return urlunparse(parsed._replace(query=urlencode(kept))) + + @staticmethod + def _warn_if_db_ahead_of_head(migrations_dir: str) -> None: + """ + Log a warning if _prisma_migrations contains applied migrations with + timestamps newer than every migration this build ships. + + This is informational only for the v2 resolver — it tells the operator + the DB was likely migrated by a newer deployment, which is usually a + signal that this (older) version shouldn't run against it.

Refactors `test_basic_python_version.py`: - Extracts the proxy spawn + smoke-test body into `_run_proxy_server_smoke_test` so the v1 and v2 tests share the same code path. - The existing `test_litellm_proxy_server_config_no_general_settings` is now a thin wrapper that passes no extra args (v1 default, unchanged). - Adds `..._v2_resolver` variant that passes `--use_v2_migration_resolver`. The existing `installing_litellm_on_python` / `installing_litellm_on_python_3_13` jobs filter out the v2 variant via `-k "not v2_resolver"` so they keep running only against their shared DB, unchanged behavior. --- .circleci/config.yml | 53 ++++++++++++++++++- .../test_basic_python_version.py | 23 +++++++- 2 files changed, 72 insertions(+), 4 deletions(-) diff --git a/.circleci/config.yml b/.circleci/config.yml index 8c75bdc5f33..db8e7d49d71 100644 --- a/.circleci/config.yml +++ b/.circleci/config.yml @@ -1529,7 +1529,50 @@ jobs: command: | pwd ls - uv run --no-sync python -m pytest -vv tests/local_testing/test_basic_python_version.py + uv run --no-sync python -m pytest -vv tests/local_testing/test_basic_python_version.py -k "not v2_resolver" + + installing_litellm_on_python_v2_migration_resolver: + docker: + - image: cimg/python:3.11 + auth: + username: ${DOCKERHUB_USERNAME} + password: ${DOCKERHUB_PASSWORD} + - image: cimg/postgres:16.0 + environment: + POSTGRES_USER: postgres + POSTGRES_PASSWORD: postgres + POSTGRES_DB: litellm_test + working_directory: ~/project + environment: + DATABASE_URL: "postgresql://postgres:postgres@localhost:5432/litellm_test" + + steps: + - checkout + - setup_google_dns + - run: + name: Install Dependencies + command: | + curl -LsSf -o /tmp/uv-install.sh https://astral.sh/uv/0.10.9/install.sh + echo "7fc46e39cb97290b57169c0c813a17970585ac519139f19006453c99b5f2f45f /tmp/uv-install.sh" | sha256sum -c - + env UV_NO_MODIFY_PATH=1 sh /tmp/uv-install.sh + rm -f /tmp/uv-install.sh + echo 'export PATH="$HOME/.local/bin:$PATH"' >> "$BASH_ENV" + export PATH="$HOME/.local/bin:$PATH" + if [ -f "$HOME/miniconda/etc/profile.d/conda.sh" ]; then + export PATH="$HOME/miniconda/bin:$PATH" + source "$HOME/miniconda/etc/profile.d/conda.sh" + conda activate myenv + fi + uv sync --frozen --all-groups --all-extras --python "$(which python)" + - setup_litellm_enterprise_pip + - wait_for_service: + url: tcp://localhost:5432 + timeout: "60" + - run: + name: Run v2 migration resolver proxy smoke test + command: | + uv run --no-sync python -m pytest -vv \ + tests/local_testing/test_basic_python_version.py::test_litellm_proxy_server_config_no_general_settings_v2_resolver installing_litellm_on_python_3_13: docker: @@ -1563,7 +1606,7 @@ jobs: command: | pwd ls - uv run --no-sync python -m pytest -v tests/local_testing/test_basic_python_version.py + uv run --no-sync python -m pytest -v tests/local_testing/test_basic_python_version.py -k "not v2_resolver" helm_chart_testing: machine: image: ubuntu-2204:2023.10.1 # Use machine executor instead of docker @@ -3544,6 +3587,12 @@ workflows: only: - main - /litellm_.*/ + - installing_litellm_on_python_v2_migration_resolver: + filters: + branches: + only: + - main + - /litellm_.*/ - helm_chart_testing: requires: - build_docker_database_image diff --git a/tests/local_testing/test_basic_python_version.py b/tests/local_testing/test_basic_python_version.py index 37e23d64677..8308e0d6033 100644 --- a/tests/local_testing/test_basic_python_version.py +++ b/tests/local_testing/test_basic_python_version.py @@ -100,8 +100,12 @@ import pytest import requests -def test_litellm_proxy_server_config_no_general_settings(): - # Sync the local litellm packages into the project environment +def _run_proxy_server_smoke_test(extra_proxy_args=None): + """Sync deps, generate Prisma client, start proxy with optional extra args, + send a health check + chat/completions request, and tear down.""" + if extra_proxy_args is None: + extra_proxy_args = [] + server_process = None try: _run_uv( @@ -144,6 +148,7 @@ def test_litellm_proxy_server_config_no_general_settings(): "litellm.proxy.proxy_cli", "--config", config_fp, + *extra_proxy_args, ], cwd=PROJECT_ROOT, ) @@ -182,3 +187,17 @@ def test_litellm_proxy_server_config_no_general_settings(): # Additional assertions can be added here assert True + + +def test_litellm_proxy_server_config_no_general_settings(): + """Exercises the default (v1) migration resolver.""" + _run_proxy_server_smoke_test() + + +def test_litellm_proxy_server_config_no_general_settings_v2_resolver(): + """Exercises the opt-in v2 migration resolver. + + Runs in a separate CI job against a local Postgres to avoid collisions + with the v1 variant when they share a database. + """ + _run_proxy_server_smoke_test(extra_proxy_args=["--use_v2_migration_resolver"]) From 88b1823f51128fdc582c411b27fe1d7903bba948 Mon Sep 17 00:00:00 2001 From: Yuneng Jiang Date: Tue, 21 Apr 2026 14:45:29 -0700 Subject: [PATCH 38/74] [Test] Fix setup_database call-signature assertions for v2 flag Existing tests pinned exact kwargs on `PrismaManager.setup_database`, but the opt-in v2 resolver added `use_v2_resolver=False` to every call.

BINARY_PATHS in the generated prisma client was baked to point into /app/.cache, so any deployment that mounts a volume there (common with securityContext.readOnlyRootFilesystem: true and an emptyDir/tmpfs for a writable cache) wipes the pre-downloaded query engine at pod startup, producing BinaryNotFoundError during connect(). Before the uv migration, prisma-python defaulted to $HOME/.cache = /root/.cache (runtime stage runs as root), which was unaffected by any /app/* volume mounts. Restore that behaviour: drop the env vars from the runtime stage, re-run prisma generate there so the query engine AND the baked BINARY_PATHS both land in /root/.cache, and remove the stale builder-stage /app/.cache (~800 MB). Dockerfile.non_root is intentionally left alone — its /app/.cache location is by design for the hardened offline-install flow. --- Dockerfile | 12 +++++++++--- docker/Dockerfile.database | 12 +++++++++--- 2 files changed, 18 insertions(+), 6 deletions(-) diff --git a/Dockerfile b/Dockerfile index a2cd1cb3ed2..0deddce3490 100644 --- a/Dockerfile +++ b/Dockerfile @@ -94,15 +94,21 @@ RUN apk add --no-cache bash openssl tzdata nodejs npm python3 libsndfile supervi { apk del --no-cache npm 2>/dev/null || true; } WORKDIR /app -ENV PRISMA_BINARY_CACHE_DIR=/app/.cache/prisma-python/binaries \ - XDG_CACHE_HOME=/app/.cache \ - PATH="/app/.venv/bin:${PATH}" +ENV PATH="/app/.venv/bin:${PATH}" COPY --from=builder /app /app RUN find /app/.venv -type f -path "*/tornado/test/*" -delete && \ find /app/.venv -type d -path "*/tornado/test" -delete +# Regenerate the Prisma client in the runtime stage so the baked-in +# BINARY_PATHS resolve to a location outside /app. Users with volume mounts +# that shadow /app/.cache (e.g. readOnlyRootFilesystem + emptyDir) would +# otherwise lose access to the pre-downloaded query engine at runtime. +# Drop the builder's /app/.cache afterwards — it's stale and adds ~800 MB +# the runtime doesn't use. +RUN rm -rf /app/.cache && prisma generate --schema=./schema.prisma + EXPOSE 4000/tcp COPY docker/supervisord.conf /etc/supervisord.conf diff --git a/docker/Dockerfile.database b/docker/Dockerfile.database index 57ecef81eb8..1eebc26731d 100644 --- a/docker/Dockerfile.database +++ b/docker/Dockerfile.database @@ -92,15 +92,21 @@ RUN apk add --no-cache bash openssl tzdata nodejs npm python3 libsndfile supervi { apk del --no-cache npm 2>/dev/null || true; } WORKDIR /app -ENV PRISMA_BINARY_CACHE_DIR=/app/.cache/prisma-python/binaries \ - XDG_CACHE_HOME=/app/.cache \ - PATH="/app/.venv/bin:${PATH}" +ENV PATH="/app/.venv/bin:${PATH}" COPY --from=builder /app /app RUN find /app/.venv -type f -path "*/tornado/test/*" -delete && \ find /app/.venv -type d -path "*/tornado/test" -delete +# Regenerate the Prisma client in the runtime stage so the baked-in +# BINARY_PATHS resolve to a location outside /app. Users with volume mounts +# that shadow /app/.cache (e.g. readOnlyRootFilesystem + emptyDir) would +# otherwise lose access to the pre-downloaded query engine at runtime. +# Drop the builder's /app/.cache afterwards — it's stale and adds ~800 MB +# the runtime doesn't use. +RUN rm -rf /app/.cache && prisma generate --schema=./schema.prisma + EXPOSE 4000/tcp COPY docker/supervisord.conf /etc/supervisord.conf From 9049f3786448e16acbccc8cb5c560c11883c50ea Mon Sep 17 00:00:00 2001 From: Yuneng Jiang Date: Tue, 21 Apr 2026 15:34:24 -0700 Subject: [PATCH 42/74] [Fix] v2 migration resolver: address Greptile review findings MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Open the psycopg connection in `_warn_if_db_ahead_of_head` with autocommit=True.

Apr 2026 15:46:47 -0700 Subject: [PATCH 45/74] Docker: drop env overrides from builder, COPY /root/.cache to runtime Follow-up on review feedback: the previous commit had the builder download the query engine into /app/.cache, then threw it away in the runtime stage and re-downloaded into /root/.cache. That doubled the build-time network fetch. Remove PRISMA_BINARY_CACHE_DIR and XDG_CACHE_HOME from the builder stage as well, so its prisma generate lands in /root/.cache with the correct path layout on its own. Drop the runtime-stage prisma generate and instead COPY --from=builder /root/.cache /root/.cache. Single download, smaller image. --- Dockerfile | 17 ++++++----------- docker/Dockerfile.database | 17 ++++++----------- 2 files changed, 12 insertions(+), 22 deletions(-) diff --git a/Dockerfile b/Dockerfile index 0deddce3490..d6c3bfad6f8 100644 --- a/Dockerfile +++ b/Dockerfile @@ -27,10 +27,8 @@ RUN apk add --no-cache \ npm \ libsndfile -ENV PRISMA_BINARY_CACHE_DIR=/app/.cache/prisma-python/binaries \ - UV_PROJECT_ENVIRONMENT=/app/.venv \ +ENV UV_PROJECT_ENVIRONMENT=/app/.venv \ UV_LINK_MODE=copy \ - XDG_CACHE_HOME=/app/.cache \ PATH="/app/.venv/bin:${PATH}" # Copy dependency metadata first for layer caching @@ -97,18 +95,15 @@ WORKDIR /app ENV PATH="/app/.venv/bin:${PATH}" COPY --from=builder /app /app +# Prisma binaries live in $HOME/.cache (default prisma-python location), +# which is /root/.cache here.

Non-connection DB errors (e.g. `InsufficientPrivilege` / 42501 if the runtime DB user lacks SELECT on `_prisma_migrations`) would propagate uncaught and crash startup — contradicting the docstring's "informational only, never blocks" guarantee. Widen the catch to `psycopg.DatabaseError` so all DB-layer errors are swallowed. - In the P3009 and P3018 idempotent-recovery paths, the call to `_resolve_specific_migration(name)` was not wrapped in its own try/except. Being inside an active `except CalledProcessError` handler, a new `CalledProcessError` from the resolve call would NOT re-enter the same handler — it would propagate out as `CalledProcessError`, past `proxy_cli.py`'s `except RuntimeError`, crashing startup with an unhandled traceback instead of the intended clean `sys.exit(2)`. Wrap both call sites to convert to RuntimeError.

Without this the fields stayed frozen at INSERT time and the last_activity_at index was misleading for any future TTL/eviction logic. Applied to all three schema.prisma copies; no migration SQL change needed (Prisma @updatedAt is a client-side annotation that doesn't touch DDL). - get_state_snapshot: report cell.total_samples instead of alpha+beta for the 'samples' field. The previous value inflated every cell by the COLD_START_MASS prior (e.g. showed 10.0 before any real traffic arrived), which confused operators reading /adaptive_router/.../state. Updated docs + the snapshot test to match. Also fixes two pre-existing merge-break syntax errors in router.py (missing ')' on the AdaptiveRouter TYPE_CHECKING import; truncated async_pre_routing_hook dispatch call for the adaptive router branch) that were masking the rest of the file from the interpreter.

Adaptive routers added via /config/reload after boot now have their queues drained. State is lazy-loaded per router on first flush tick (new _state_loaded flag on AdaptiveRouter) so hot-reloaded routers still get their persisted priors. P2: _finalize_adaptive_router_if_configured now prunes stale AdaptiveRouterPostCallHook callbacks from every litellm callback list before registering new ones. Without this, every Router replacement left the old hooks wired up in litellm.callbacks and double-fired signal recording for every request. Uses logging_callback_manager.remove_callbacks_by_type (same pattern as the semantic tool filter). CI fixes: - black --check failure: reformatted litellm/router.py - schema migration diff: aligned @@index with the explicit index name ('idx_adaptive_router_session_activity') from the original migration by adding 'map:' to all three schema.prisma copies.

Updating one member's budget via `/team/member_update` mutated the shared row and silently changed every other member's budget too. Now both write paths produce a private, per-member budget: - `add_new_member` clones the team's default budget into a fresh row when a member is added without `max_budget_in_team`/`allowed_models`. If no team default exists, the membership is created with no budget. - `_upsert_budget_and_membership` detects when an existing membership still points at the team's default budget id and clones-on-write, relinking the membership to the new private budget before applying the update. - `team_member_update` reads `team_member_budget_id` from team metadata and passes it through so the helper can make this distinction. Adds unit tests for clone-on-write, in-place update of a private budget, and the no-default-no-budget add path.

Moved: litellm/proxy/db/db_transaction_queue/adaptive_router_update_queue.py → litellm/router_strategy/adaptive_router/update_queue.py tests/test_litellm/proxy/db/db_transaction_queue/ test_adaptive_router_update_queue.py → tests/test_litellm/router_strategy/adaptive_router/test_update_queue.py Also switched the queue's logger from verbose_proxy_logger to verbose_router_logger to match the new module's ownership. P2 review: drop unused constant STAGNATION_JACCARD_EXACT from config.py — it was defined but never referenced.

Bumping uv version or SHA is now a one-line change instead of 43.

Replace all 11 inline docker run / wait_for_service blocks with a single - start_postgres call. The helm chart test overrides db_name to litellm_test; everything else uses the default. One of the 11 sites previously used a bespoke pg_isready loop instead of wait_for_service; it now goes through the same TCP-probe path everyone else uses, which is sufficient for test ordering purposes.

Consolidate base images on cimg/python:3.12. Jobs previously on 3.11 (26 jobs), 3.9 (1 historical: upload-coverage), and an incidental 3.13.1 (litellm_assistants_api_testing) now use 3.12. - installing_litellm_on_python_3_13 keeps cimg/python:3.13.1 as its explicit "latest Python supported" install-check matrix job. Machine-executor jobs: - Delete the miniconda install step from 10 jobs. uv now manages Python directly: uv sync --python 3.12 auto-downloads a python-build-standalone interpreter if the ubuntu-2204 base image's default python doesn't match. - Remove 37 "if [ -f conda.sh ]; then conda activate myenv" wrappers and 2 unconditional conda activate blocks left behind from the conda days. - proxy_build_from_pip_tests keeps its 3.13 target (it was conda create -n myenv python=3.13) via uv sync --python 3.13.

Bumped everything to 2024.04.1. - Remove the legacy "version: 2" inside the workflows: block — CircleCI 2.1 top-level already declares the version. - Drop `{{ checksum ".circleci/config.yml" }}` from cache keys (13 sites). It was busting the cache on every unrelated config edit; the uv.lock checksum alone is the right dependency cache key. - Add partial-restore fallbacks to every restore_cache with a single templated key (10 sites).

Four CCI jobs moved to new or extended GHA workflows: 1. check_code_and_doc_quality (was 25 runs: ruff + import-safety + 21 code_coverage_tests + 3 documentation_tests + circular-imports). - The 21 tests/code_coverage_tests/*.py scripts and the 3 tests/documentation_tests/*.py scripts run in the new .github/workflows/test-code-quality.yml workflow. - ruff, import-safety, and circular-imports were already run by .github/workflows/test-linting.yml — no new migration needed. - The 3 documentation_tests scripts read docs/my-website/docs/proxy/config_settings.md. Since docs have moved to BerriAI/litellm-docs, the GHA workflow checks out that repo and symlinks docs/my-website -> the checkout so the existing hardcoded paths resolve without touching the scripts. The stale local docs/my-website/ copy in this repo will be removed in a separate PR. 2. semgrep (custom-rule SAST against .semgrep/rules). - New .github/workflows/test-semgrep.yml. 3. installing_litellm_on_python + installing_litellm_on_python_3_13 (pip install compat checks on Python 3.12 and 3.13). - New .github/workflows/test-install-litellm.yml as a matrix job. - 3.12 run also verifies litellm_enterprise import; 3.13 run skips that check (matches previous CCI behavior). - installing_litellm_on_python_v2_migration_resolver stays in CCI because it requires a postgres service.

All N requests are made up front, so a single dropped Redis write no longer kills the test. Add /health/readiness checks at test start and on poll timeout so the failure message surfaces proxy state (db, cache) instead of "calibration timed out".

Addresses the ConnectionTimeoutError observed on the first /key/info call after the 20 chat completions. --- .../test_spend_accuracy_tests.py | 31 +++++++++++++++++-- 1 file changed, 28 insertions(+), 3 deletions(-) diff --git a/tests/spend_tracking_tests/test_spend_accuracy_tests.py b/tests/spend_tracking_tests/test_spend_accuracy_tests.py index 8c523e91919..15e00d93356 100644 --- a/tests/spend_tracking_tests/test_spend_accuracy_tests.py +++ b/tests/spend_tracking_tests/test_spend_accuracy_tests.py @@ -48,6 +48,22 @@ POLL_TIMEOUT_SECONDS = 60 TOLERANCE = 1e-10 +def _make_test_session() -> aiohttp.ClientSession: + """ + Session tuned for CI reliability: + - force_close: avoid aiohttp reusing a TCP connection that the proxy/kernel + silently closed during the long idle window between setup POSTs and the + later poll loop (observed failure mode: ConnectionTimeoutError on the + first /key/info call after 20 chat completions). + - explicit connect timeout: surface a blocked proxy event loop quickly + instead of hanging on aiohttp's 5-minute default total timeout. + """ + return aiohttp.ClientSession( + connector=aiohttp.TCPConnector(force_close=True), + timeout=aiohttp.ClientTimeout(total=30, connect=10), + ) + + async def create_organization(session, organization_alias: str): """Helper function to create a new organization""" url = "http://0.0.0.0:4000/organization/new" @@ -156,7 +172,16 @@ async def poll_key_spend_until(session, key: str, expected: float) -> float: start = time.time() last_spend = 0.0 while time.time() - start < POLL_TIMEOUT_SECONDS: - key_info = await get_spend_info(session, "key", key) + try: + key_info = await get_spend_info(session, "key", key) + except (aiohttp.ClientError, asyncio.TimeoutError) as exc: + print( + f"Transient transport error during spend poll: " + f"{type(exc).__name__}: {exc}.
