Fixes test_log_langfuse_v2_handles_null_usage_values flaky test failure
by properly cleaning up sys.modules['langfuse'] in tearDown.
Changes:
- Store original langfuse module in setUp before mocking
- Restore original or remove mock in tearDown to prevent state pollution
- Remove invalid print_verbose parameter from log_event_on_langfuse
Root Cause:
The tearDown method was not cleaning up sys.modules['langfuse'] after
each test, causing mock state to leak between tests. This caused
intermittent failures in CI, especially when tests run in parallel or
in different orders.
Impact:
This test has a long history of flakiness with multiple attempted fixes
(#20475, #17599, #17594, #17591, #17588). The missing sys.modules cleanup
was the underlying issue causing continued failures despite those patches.

Address three additional root causes that prevented connection cleanup
on client disconnect: Starlette/Uvicorn disconnect detection gap,
content= vs stream= no-op wrapper in aiohttp transport, and anyio
CancelledError interrupting cleanup awaits.
- Add `definitions` handling alongside `$defs` in schema normalization
(older JSON Schema drafts use `definitions` instead of `$defs`)
- Fall back to tool-call approach when `response_format: {type: json_object}`
has no explicit schema, since the native API requires one
- Add tests for both cases

* Pyroscope: require PYROSCOPE_APP_NAME and PYROSCOPE_SERVER_ADDRESS, add UTF-8 locale hint
- No defaults for PYROSCOPE_APP_NAME or PYROSCOPE_SERVER_ADDRESS; fail at startup if unset when Pyroscope is enabled
- Set LANG/LC_ALL to C.UTF-8 when unset to reduce malformed_profile (invalid UTF-8) rejections
- Startup message suggests PYTHONUTF8=1 if server rejects profiles
- Simplify LITELLM_ENABLE_PYROSCOPE in config_settings; document Pyroscope env vars as required with no default
- Add pyroscope_profiling to sidebar (Alerting & Monitoring)
- pyproject.toml: pyroscope-io as required dep on non-Windows (marker), in proxy extra
* proxy: add PYROSCOPE_SAMPLE_RATE env, use verbose logging, fix int type
- Add optional PYROSCOPE_SAMPLE_RATE env (integer, no default)
- Pass sample_rate to pyroscope.configure() as int for pyroscope-io
- Replace print with verbose_proxy_logger (info/warning)
- Document PYROSCOPE_SAMPLE_RATE in config_settings.md
* Address Greptile PR feedback: Pyroscope optional, docs, tests, docstring
- pyproject.toml: mark pyroscope-io as optional=true (proxy extra only)
- Add docs/my-website/docs/proxy/pyroscope_profiling.md (fix broken sidebar link)
- Add tests/test_litellm/proxy/test_pyroscope.py for _init_pyroscope()
- proxy_server: fix _init_pyroscope docstring (required server/app name, sample rate as int)
* Update litellm/proxy/proxy_server.py

* fix: populate identity fields in proxy admin JWT early-return path
When is_proxy_admin is True, the UserAPIKeyAuth early-return now includes
user_id, team_id, team_alias, team_metadata, org_id, and end_user_id
resolved from the JWT. Previously only user_role and parent_otel_span
were set, causing blank Team Name and Internal User in Request Logs UI.
* test: add unit tests for proxy admin JWT identity fields
* fix: add custom_body parameter to endpoint_func in create_pass_through_route
The bedrock_proxy_route calls `endpoint_func(custom_body=data)` to
pass a pre-parsed, SigV4-signed request body. However, the
`endpoint_func` closure created by `create_pass_through_route` does
not accept a `custom_body` keyword argument, causing:
TypeError: endpoint_func() got an unexpected keyword argument 'custom_body'
Add `custom_body: Optional[dict] = None` to both `endpoint_func`
definitions (adapter-based and URL-based). In the URL-based path,
when `custom_body` is provided by the caller, use it instead of
re-parsing the body from the raw request.
Fixes#16999
* Add tests for custom_body handling in create_pass_through_route
Address reviewer feedback on PR #20849:
- Document why the adapter-based endpoint_func accepts custom_body
for signature compatibility but does not forward it (the underlying
chat_completion_pass_through_endpoint does not support it).
- Add test_create_pass_through_route_custom_body_url_target: verifies
that when a caller (e.g. bedrock_proxy_route) supplies custom_body,
it takes precedence over the body parsed from the raw request.
- Add test_create_pass_through_route_no_custom_body_falls_back:
verifies that the default path (no custom_body) correctly uses the
request-parsed body, preserving existing behavior.
Both tests are fully mocked following the project's CONTRIBUTING.md
guidelines and the patterns established in the existing test file.

- Fast-path early return in check_api_key_for_custom_headers_or_pass_through_endpoints
- startswith(tuple) replaces for-loop substring matching (also more correct)
- Pre-compute _PUBLIC_ROUTES and MAPPED_PASS_THROUGH_PREFIXES at module level
- Deduplicate get_request_route call by passing route as parameter
- Cache dict(request.headers) on request.state per-request
- Remove redundant elif branch from get_api_key (handled by later function)
- Fix: isinstance(request.headers, dict) was always False for Starlette Headers,
silently breaking custom header extraction for pass-through endpoints
