Smoke Zenoh Mqtt Ps Zenoh Publisher Mqtt Subscriber

Scope

Run and validate this binary set:

• Broker: utils/mosquitto/docker-compose.yaml
• Streamer: configurable-streamer
• Publisher: example-streamer-uses bin zenoh_publisher
• Subscriber: example-streamer-uses bin mqtt_subscriber

Execution

1. Setup from repo root:
   • source build/envsetup.sh highest
   • export REPORT_DIR="$OPENCODE_CONFIG_DIR/reports/transport-smoke-skills/smoke-zenoh-mqtt-ps-zenoh-publisher-mqtt-subscriber"
   • mkdir -p "$REPORT_DIR"
2. Build binaries:
   • cargo build -p configurable-streamer
   • cargo build -p example-streamer-uses --bin zenoh_publisher --features zenoh-transport
   • cargo build -p example-streamer-uses --bin mqtt_subscriber --features mqtt-transport
3. Start broker:
   • docker compose -f utils/mosquitto/docker-compose.yaml up -d
4. Start streamer from configurable-streamer:
   • source ../build/envsetup.sh highest
   • RUST_LOG="up_streamer=debug,up_transport_mqtt5=debug" cargo run -- --config "CONFIG.json5" > "$REPORT_DIR/streamer.log" 2>&1 & echo $! > "$REPORT_DIR/streamer.pid"
5. Start subscriber from repo root (aligned with static subscription sink URI):
   • source build/envsetup.sh highest
   • RUST_LOG=info cargo run -p example-streamer-uses --bin mqtt_subscriber --features mqtt-transport -- --uauthority authority-a --uentity 0x5678 --uversion 0x1 --resource 0x1234 --source-authority authority-b --source-uentity 0x3039 --source-uversion 0x1 --source-resource 0x8001 --broker-uri localhost:1883 > "$REPORT_DIR/subscriber.log" 2>&1 & echo $! > "$REPORT_DIR/subscriber.pid"
6. Run publisher from repo root:
   • source build/envsetup.sh highest
   • export RUST_LOG="info,example_streamer_uses=debug"
   • timeout 45s cargo run -p example-streamer-uses --bin zenoh_publisher --features zenoh-transport > "$REPORT_DIR/publisher.log" 2>&1; printf '%s\n' "$?" > "$REPORT_DIR/publisher.exit"

Validation

• Publisher emitted traffic: rg -n "Sending Publish message" "$REPORT_DIR/publisher.log"
• Subscriber received traffic: rg -n "PublishReceiver: Received a message" "$REPORT_DIR/subscriber.log"
• Streamer forwarded traffic: rg -n "Sending on out_transport succeeded" "$REPORT_DIR/streamer.log"

Pass only when all three checks match.

Teardown

• kill -INT "$(cat "$REPORT_DIR/subscriber.pid")" "$(cat "$REPORT_DIR/streamer.pid")" || true
• If still alive: kill -TERM "$(cat "$REPORT_DIR/subscriber.pid")" "$(cat "$REPORT_DIR/streamer.pid")" || true
• docker compose -f utils/mosquitto/docker-compose.yaml down
• Verify: pgrep -fa "configurable-streamer|zenoh_publisher|mqtt_subscriber" || true
