Bug: requests.post in utils/call_llm.py has no timeout, hangs indefinitely on slow/stuck upstream

[chirag127]

Problem

_call_llm_provider in utils/call_llm.py calls requests.post(...) with no timeout= kwarg, so a slow/stuck upstream (Ollama, XAI, OpenRouter, self-hosted) hangs the whole tutorial run forever. The except requests.exceptions.Timeout handler at line 120 is dead code.

Cite

utils/call_llm.py:104 — response = requests.post(url, headers=headers, json=payload)
utils/call_llm.py:120 — except requests.exceptions.Timeout: (unreachable).

Steps

1. Set LLM_PROVIDER=OLLAMA, OLLAMA_BASE_URL=http://10.255.255.1:11434 (unroutable), OLLAMA_MODEL=llama3.
2. python main.py --repo https://github.com/octocat/Hello-World.

Expected

Abort with timeout error after ~30s.

Actual

Process hangs indefinitely; only Ctrl-C exits.

Env

Python 3.10-slim (Dockerfile); requests>=2.28.0 (requirements.txt).

Fix

requests.post(url, headers=headers, json=payload, timeout=(10, 300)).
