mgf-http — typed async HTTP client for mgf-common consumers

Sibling of mgf-common under the mgf.* namespace. Houses the typed httpx wrapper that previously lived under mgf.common.http.* — extracted at mgf-common v0.29 / mgf-http v0.1 per the federation split plan.

What this provides

Submodule	What
mgf.http	AsyncHttpClient — thin wrapper over httpx.AsyncClient with retries, timeouts, header redaction, OTel-aware logging, typed error translation. RetryPolicy — exponential backoff with jitter; per-request override.
mgf.http.exceptions	HttpTransportError(OperationError) — transport-layer failure (timeout, connect-refused, network unreachable). Renamed from HttpClientError at the v0.29 cutover to disambiguate from mgf.common.exceptions.HttpClientError (the HTTP-01 4xx-class hierarchy parent, which stays in mgf-common).

Install

pip install mgf-http
# Or with the test extra (respx for mocking httpx in your tests):
pip install 'mgf-http[test]'

Pulls in mgf-common and httpx automatically.

Quick start

import asyncio
from mgf.http import AsyncHttpClient, RetryPolicy

async def main() -> None:
    async with AsyncHttpClient(
        base_url="https://api.example.com",
        timeout=10.0,
        retry=RetryPolicy(max_attempts=3),
    ) as http:
        response = await http.get("/users", params={"page": 1})
        response.raise_for_status()
        users = response.json()

asyncio.run(main())

The client auto-derives a User-Agent of the shape <app>/<ver> mgf-http/<libver> from mgf.common.app_name() / mgf.common.app_version() (call mgf.common.bootstrap() at startup for accurate identity). Authorization / Cookie / X-Api-Key family headers are redacted in logs and OTel spans automatically.

Documentation

• docs/recipes/http.md — full HTTP-client walkthrough.
• docs/cutover/v0.1.0.md — maiden voyage migration story (the v0.29 split, including the HttpClientError → HttpTransportError rename).
• PUBLIC_API.md — full public surface contract.
• CHANGELOG.md — release history.

For the federation-wide engineering standards (DESIGN_PRINCIPLES, ERROR_HANDLING, SECURITY, etc.) see mgf-common/docs/standards/. This sibling inherits them by reference; the standards source-of-truth lives in mgf-common.

Status

🚧 Experimental — every public name is experimental per AP-09. Promotion to stable happens release-by-release as consumer feedback in mgf-common/FEEDBACK.md converges. The 0.x window applies. Pin tightly: mgf-http = ">=0.X.0,<0.Y".
