fix(responses): keep the provider code and message on top-level stream error events (#46438)
* fix(responses): keep the provider code and message on top-level stream error events

Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com>

* fix(responses): log a mid-stream failure before the router falls back

CustomStreamWrapper now waits for failure logging before it raises the
error the router falls back on, so the cooldown lands on the deployment
that failed instead of the fallback that replaced it. Also keeps numeric
error codes and the top-level message on the WebSocket and ChatGPT paths.

* fix(streaming): run sync failure callbacks before a failed stream falls back to another deployment

The router cools a deployment down from a sync failure callback that reads the request's model_info. A failed stream submitted that callback to the logging executor without waiting, so it often ran after the router's fallback had overwritten model_info and cooled down the healthy fallback deployment instead, leaving the model group with no deployments

* test(responses): cover top-level OpenAI stream error events end to end

* test(streaming): read live worker pids so the second SIGKILL chaos variant sees two workers

* fix(streaming): run waited sync failure logging off the shared logging pool

* revert(streaming): keep failed-stream failure logging in the background

Waiting for sync failure callbacks before a failed stream raises fixed the router cooldown race, but it slowed healthy calls under many failing streams with a slow callback, since the wait shares a thread pool with every call's start. The race is pre-existing on main and is tracked separately, so this PR goes back to main's logging timing and keeps only the top-level error event changes

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/unit

This folder can only run mock tests.
