Package Description

Core test for memory: one state held for the whole run while a 500 Hz timer, a publisher, a subscriber receiving its 1 kB messages, an updatable component and an updatable behavior keep the polling loop busy.

No additional authors.

sm_coretest_idle_load_1

Core test for memory. The machine enters one state and stays in it while the polling loop works. It is not a reference state machine; it exists so that smacc2_performance_tools/core_test_tools/memory_tests/idle_load_soak.sh can watch the process’s memory, threads and file descriptors over hundreds of thousands of loop iterations, timer ticks and messages. Most robots spend most of their time like this: in one state, with data arriving.

What runs while StIdle is active

Object What it does
CpRos2Timer fires at 500 Hz
CpLoadDriver a component connected to the timer signal; publishes a 1 kB std_msgs/String on each tick, and is an updatable
CpTopicPublisher, CpTopicSubscriber the same topic, /sm_coretest_idle_load_1/data; the subscriber posts EvTopicMessage for every message, which no state consumes, and emits its signal
CbMessageCounter a behavior connected to the subscriber’s signal, and an updatable; logs a count at FATAL every 1000 messages

With signal_detector_loop_freq at 2000 the machine receives 500 messages and runs 2000 updates of each updatable a second.

The deliberate leak

With SM_CORETEST_IDLE_LEAK=1 in the environment CbMessageCounter keeps every message it receives, about 0.5 MB a second. It is there to check the soak itself: a run with it set must fail.

Run

ros2 launch sm_coretest_idle_load_1 sm_coretest_idle_load_1.launch.py

The launch file tees the node output to /tmp/sm_coretest_idle_load_1_latest.log.

Not in the sanitizer gate

.github/scripts/sanitizer_core_tests.sh does not run this machine. It was run by hand for 60 seconds under TSan and under ASan on 2026-11-14 (29,000 messages each) with no report.

Package Description

Core test for memory: one state held for the whole run while a 500 Hz timer, a publisher, a subscriber receiving its 1 kB messages, an updatable component and an updatable behavior keep the polling loop busy.

No additional authors.

sm_coretest_idle_load_1

Core test for memory. The machine enters one state and stays in it while the polling loop works. It is not a reference state machine; it exists so that smacc2_performance_tools/core_test_tools/memory_tests/idle_load_soak.sh can watch the process’s memory, threads and file descriptors over hundreds of thousands of loop iterations, timer ticks and messages. Most robots spend most of their time like this: in one state, with data arriving.

What runs while StIdle is active

Object What it does
CpRos2Timer fires at 500 Hz
CpLoadDriver a component connected to the timer signal; publishes a 1 kB std_msgs/String on each tick, and is an updatable
CpTopicPublisher, CpTopicSubscriber the same topic, /sm_coretest_idle_load_1/data; the subscriber posts EvTopicMessage for every message, which no state consumes, and emits its signal
CbMessageCounter a behavior connected to the subscriber’s signal, and an updatable; logs a count at FATAL every 1000 messages

With signal_detector_loop_freq at 2000 the machine receives 500 messages and runs 2000 updates of each updatable a second.

The deliberate leak

With SM_CORETEST_IDLE_LEAK=1 in the environment CbMessageCounter keeps every message it receives, about 0.5 MB a second. It is there to check the soak itself: a run with it set must fail.

Run

ros2 launch sm_coretest_idle_load_1 sm_coretest_idle_load_1.launch.py

The launch file tees the node output to /tmp/sm_coretest_idle_load_1_latest.log.
