python.http_retry

Stability Medium

Detects HTTP calls without retry logic for transient failures.

Why It Matters

Missing HTTP retries:

• Single-point failures — One network blip breaks everything
• Poor reliability — Transient errors not recovered
• User frustration — Failed requests that would succeed on retry

Example

# ❌ Before (no retry)
import httpx

async def fetch_data():
    async with httpx.AsyncClient() as client:
        return await client.get(url)

# ✅ After (with retry)
from tenacity import retry, stop_after_attempt, wait_exponential

@retry(stop=stop_after_attempt(3), wait=wait_exponential(multiplier=1, max=10))
async def fetch_data():
    async with httpx.AsyncClient() as client:
        response = await client.get(url)
        response.raise_for_status()
        return response.json()

What Unfault Detects

• HTTP calls without retry decorator
• Missing tenacity/backoff usage
• No retry on specific status codes
