* fix(router): keep provider response headers on streaming chat completions The Router re-wraps a deployment's CustomStreamWrapper in FallbackStreamWrapper (and its sync twin) so a mid-stream failure can fail over. Neither wrapper forwarded `_response_headers`, so every streaming chat completion handed the proxy's callbacks and its response-header builder a wrapper with no provider headers, and a successful mid-stream fallback still published the failed deployment's identity, `x-request-id` and rate limit counters. Forward `_response_headers` into both wrappers, repoint the wrapper at the deployment that served the stream once a fallback takes over, and rebuild the proxy's response headers from that deployment while `create_response` still has the first chunk buffered. * fix(router): follow a nested fallback to the deployment that served the stream A fallback the router picks is itself a fallback-aware wrapper, and it only repoints at its own fallback once it yields, so reading its hidden params at selection time named a deployment that produced no output. Re-read them when the first fallback item arrives, which is still before the proxy commits response headers. Also addresses review feedback: the streaming header builder reads self.data instead of taking a coarse request_data parameter, and the new test recorder local is Final. * test(router): cover the fallback header adoption helper directly The router_code_coverage gate wants every router.py function named in a router test, and this also pins the weak-reference behavior: a wrapper collected mid-stream must not break the generator still draining it. * refactor(proxy): take a read-only mapping for the model-id lookup _get_model_id_from_response only reads its request payload, so a Mapping says what it needs and the two metadata hops are narrowed instead of assumed to be dicts. * test: drop mutable recorder locals and routine comments from the new tests An AsyncMock await_count and an asyncio.Event say the same thing as a list and a dict that the test mutates. * chore(router): justify the two rebinds in the fallback loops Both are the one-shot re-read that follows a nested fallback, so they get the repo's rebind-ok note like the rest of the file. |

In total litellm runs 1000+ tests
[02/20/2025] Update:
To make it easier to contribute and map what behavior is tested,
we've started mapping the litellm directory in tests/test_litellm
This folder can only run mock tests.
