LiteLLM all-smokes readiness: ask + diffs (TTL 15m)

Mini‑Agent + Router Readiness — All‑Smokes Orchestration Timeout (Request for Focused Help) Created: 2025-09-27 TTL: Please treat as private and ephemeral; delete within 15 minutes after review.

1. Context and Goal

• Project: LiteLLM fork with env‑gated codex‑agent provider and Mini‑Agent + Readiness system.
• Deploy gate we want: make project-ready-all must pass, i.e., EVERY smoke (smoke, smoke_optional, ndsmoke, ndsmoke_e2e) green.
• Current state: All failing clusters are fixed; individual smokes pass in isolation. The composite readiness check all_smokes times out in the harness despite extending per‑check timeout.

2. What’s Working (evidence-based)

• Agent Proxy
  • /agent/run “echo” backend delegates to arouter_call → test_agent_proxy_run_minimal passes.
  • Header precedence env vs request → test_agent_proxy_headers_precedence passes.
  • Storage trace schema minimal (iterations surfaced) → test_storage_hook_schema_minimal passes.
• HTTP Tools Invoker
  • Accepts test doubles without json= kwarg and returns text on non‑JSON body → test_http_tools_invoker_non_json_body passes.
• Router
  • Streaming parity/fallback/metrics smokes pass.
  • parallel_acompletions / parallel_as_completed fixed to use extracted helpers; both smokes pass.
  • Per‑request timeout enforced even if instance is monkeypatched → test_router_timeout_param_enforced passes.
• Mini‑Agent
  • Low E2E finalize (shim guarded), escalation high (short‑circuit chutes), live code loop, compress_runs iterate, and France Q&A now pass with local models (glm4:latest, qwen2.5-coder:3b).
• Node gateway
  • run_codex tool presence/501 works; port collisions solved by freeing :8791 and stopping docker tools‑stub if mapped.
• Codex‑Agent e2e (low)
  • OK when codex-agent base uses shim OpenAI endpoint in echo mode to avoid recursion.

3. The Problem

• All isolation runs green, but the configured readiness check named all_smokes (single monolithic run that executes tests/smoke tests/smoke_optional tests/ndsmoke tests/ndsmoke_e2e) hits a TIMEOUT inside scripts/mvp_check.py in strict mode. Raising ALL_SMOKES_TIMEOUT up to 900–1200s still sees the harness terminate the overall job after ~20 minutes on this box.
• This is orchestration wall‑clock, not red tests.

4. What I Tried

• Increased configured check timeout for name=="all_smokes" (mvp_check.py) to read ALL_SMOKES_TIMEOUT, default 900.
• Optimized run_all_smokes.py to:
  • Guard shim (free port or reuse; prefer real providers; OpenAI shim echo for codex‑agent path only).
  • Set env defaults for models (LITELLM_DEFAULT_CODE_MODEL=ollama_chat/qwen2.5-coder:3b; LITELLM_DEFAULT_TEXT_MODEL=ollama_chat/glm4:latest; OLLAMA_MODEL=glm4:latest).
  • Kill docker tools‑stub mapping :8791 if present to avoid flake in node gateway smoke.
  • Free 8791 and 8788 when necessary.
• Verified previously failing clusters by running their specific tests directly (green).

5. Request (Please respond with unified diffs that apply cleanly) A) Split all_smokes into two configured checks in readiness.yml to avoid single long job:
   • all_smokes_core → pytest -q tests/smoke tests/smoke_optional -q
   • all_smokes_nd → pytest -q tests/ndsmoke tests/ndsmoke_e2e -q
   • Extend mvp_check.py to support per-check timeouts: ALL_SMOKES_CORE_TIMEOUT / ALL_SMOKES_ND_TIMEOUT (defaults 600–900s).
   • Ensure both checks export the same env defaults used by scripts/run_all_smokes.py.

B) Optional runtime speed-ups (safe):

• scripts/run_all_smokes.py: If pytest‑xdist is present, allow -n auto; allow -k shard env for CI.
• Expose PYTEST_ADDOPTS passthrough.

C) Make target:

• make project-ready-all-split that runs the two checks in strict mode, updates PROJECT_READY.md, and fails on any red.

D) Sanity: Keep codex-agent OpenAI shim in echo mode in the readiness path to avoid recursion; keep real providers for all other paths.

7. Logs showing TIMEOUT in composite run

• mvp_check output (strict):
  • “… Configured check: all_smokes — TIMEOUT …”
  • Earlier in the same run: all configured sub‑checks green; only the composite check hits the time ceiling.

8. Proposed Acceptance

• Both split checks pass in strict mode; PROJECT_READY.md shows READY with both all_smokes_core and all_smokes_nd green.
• Overall runtime for each split on a dev host: ~6–9 minutes per block (subject to CPU), total < 18 minutes.

9. Anything else you want us to try?

• Happy to wire -n auto via xdist if allowed.
• If you prefer retaining a single all_smokes block, suggest a resilient runner strategy that survives >20 min without CI kill.
