ZMQRuntime

Generic ZeroMQ transport, lifecycle, progress, cancellation, viewer-control, and execution-projection primitives.

Important boundary

ZMQServer and ZMQClient are abstract application integration points. They cannot be instantiated directly:

a server implements handle_control_message and handle_data_message;
a client implements _spawn_server_process and send_data.

The package does not provide a generic send_request API or define an application's execution payload. Applications subclass the bases and map their typed domain requests onto the transport.

Transport configuration

from zmqruntime import TransportMode, ZMQConfig
from zmqruntime.transport import get_zmq_transport_url

config = ZMQConfig(control_port_offset=1000)
data_url = get_zmq_transport_url(
    7777,
    host="localhost",
    mode=TransportMode.TCP,
    config=config,
)

Application subclasses can use serve_forever, readiness probes, control port helpers, progress records, cancellation messages, lifecycle engines, and projection adapters without duplicating socket or process machinery.

Execution completion

Execution clients with a registered progress subscription wake on the server's terminal ExecutionStatusSnapshot. The existing callback sequence barrier still waits for every admitted progress callback. Registration replays the latest progress and terminal record; a missing terminal notification recovers through STATUS using the configured wait interval. Clients without progress registration continue to use STATUS.

Applications that enrich successful results override ExecutionServer.finalize_execution_record(record). This record-only hook runs under the lifecycle lock after task completion and before STATUS or terminal publication can observe the record. It must not publish progress or acquire transport resources. The task's recorded end time retains its existing boundary. Already admitted progress is published before the terminal record; new progress admissions after a terminal transition are discarded.

Installation

python -m pip install zmqruntime
