service-bus (Python) — TODO

Done (0.1.0)

  • Service ABC + BaseService (status tracking, send, on_start/on_stop hooks); ServiceStatus enum.
  • ServiceBus: register / register_and_start_service(s) / start_all_registered; start_service / stop_service / unregister_service (threaded).
  • Discovery: get_service(name), find_running_services(type_or_predicate), running_services() / registered_services(), is_registered / is_running.
  • await_running(timeout, *names).
  • pause / unpause / restart / shutdown / graceful_shutdown; context manager.
  • Per-service ServiceStatus tracking + listeners; UNSTABLE -> restart.
  • Control commands via headers["command"] + headers["service"].
  • Reusable Daemon base (hooks + launch).
  • python -m service_bus demo; test suite; README.md, DESIGN.md.

Next

  • register_and_start_service_sync(service, timeout) — register + start + await.
  • Real dependency ordering for start using depends_on() (topological sort).
  • Factory registration (register(name, lambda: S())) so depends_on() can auto-register and control-command register works over the bus.
  • Readiness gate: hold delivery to a service until it reports RUNNING.
  • Health policy beyond "UNSTABLE -> restart": restart backoff, give-up threshold.
  • Control-command responses (ack/nack back to the sender).
  • Surface seda-bus stats() per service.
  • Free-threaded (python3.14t) test run in CI alongside the GIL build.
  • Publish to PyPI (currently a path dependency on ../seda-bus-python).
  • [tool.hatch.metadata] allow-direct-references + a seda-bus @ file:// pin so a fresh pip install -e . resolves the sibling without a separate step.
