fetchurl Python SDK
Protocol-level client for fetchurl content-addressable cache servers.
Zero runtime dependencies — uses only the Python standard library. Works with any HTTP library via Fetcher / AsyncFetcher protocols.
Install
pip install fetchurl-sdk
# or
uv add fetchurl-sdk
Protocol
Normative behavior: fetchurl/spec (SPEC.md).
Reference server: fetchurl/fetchurl.
Usage
from fetchurl import fetch, UrllibFetcher, parse_fetchurl_server
import os
servers = parse_fetchurl_server(os.environ.get("FETCHURL_SERVER", ""))
# Or drive FetchSession yourself with your HTTP client — see package docstring.
Clients must treat the server as untrusted and verify the hash (this SDK does that for you).
Environment
| Variable | Meaning |
|---|---|
FETCHURL_SERVER |
Server base URL(s) per the spec. Empty/absent disables server use. |
Development
uv sync --dev
uv run python -m unittest test_fetchurl.py
# Integration (Docker + image):
# FETCHURL_TEST_IMAGE=fetchurl:local uv run --extra test python -m unittest test_fetchurl_integration.py
