Description

Hello, I'm trying to benchmark the middleware implementations like rmw_zenoh, rmw_cyclonedds and rmw_fastrtps. I have implemented some benchmark codes for comparing how middlewares behave at basic topic subscription-publishing scenario. My benchmark code exits with SIGSEV exit code whereas rmw_fastrtps exits cleanly. Here is backtrace. Seems problem occurs while trying to deallocate some data.

Bactrace:

How to reproduce

I actually work on source installation, but maybe you want to try it. Ping me in any case you struggle, because i haven't run this docker for long time.

If you want to install from source, you can use this repo (https://github.com/CihatAltiparmak/moveit_middleware_benchmark/tree/feature/benchmark_simple_sub_pub_topics)

Pull this docker image

docker pull ghcr.io/cihataltiparmak/moveit_middleware_benchmark:latest

inside docker:

Terminal 1

cd ws_moveit/src/moveit_middleware_benchmark
git checkout feature/benchmark_simple_sub_pub_topics
cd ../../
colcon build --packages-select rmw_zenoh_cpp moveit_middleware_benchmark --cmake-args -DCMAKE_BUILD_TYPE=Debug
source /opt/ros/rolling/setup.bash
source install/setup.bash
export RMW_IMPLEMENTATION=rmw_zenoh_cpp
# don't forget to run zenoh_router in Terminal 2
ros2 launch moveit_middleware_benchmark scenario_basic_subscription_benchmark.launch.py

Terminal 2

docker exec -it <your_container_id> bash
# inside docker
export RMW_IMPLEMENTATION=rmw_zenoh_cpp
ros2 run rmw_zenoh_cpp rmw_zenohd

Additional information:

It would be better for you to change default scenario_basic_subscription_benchmark.launch.py codes with https://gist.githubusercontent.com/CihatAltiparmak/a22c4963223b88e49ff29fa47350bb57/raw/5686664dacc8a5c32babd14edf1d917f4b8c6068/scenario_basic_subscription_benchmark.launch.py in order to debug and to decrease benchmark repetitions from 6 to 2.

[CihatAltiparmak]

After some investigation, i found that &guard_condition->context->options.allocator->deallocate; is NULL and rmw_zenoh tries to use allocator->deallocate(guard_condition->data, allocator->state); in order to shutdown node.

[Yadunund]

Thanks for reporting this issue. I will try to reproduce it. In general I think we need to update our implementation throughout to check that the allocator is valid using RCUTILS_CHECK_ALLOCATOR before attempting to use it.

[CihatAltiparmak]

Hello @Yadunund , I feel like it's not enough to add RCUTILS_CHECK_ALLOCATOR to rmw_destroy_guard_condition(maybe it should not be added.) . Because i guess there are still some dataraces and this dataraces give rise to write to some forbidden sections of memory. This is one of the backtrace logs. I have a lot of backtrace log. Some of them points out rmw_destroy_node and some of them is related to sub_data_handler. I have seen your PR's. Let's be patient. After merging your PRs about the thread safety, i will try rmw_zenoh on my code again and i will give feedback. I found an error in my code but this error isn't triggered at other middleware implementation.(rmw_fastrtps and rmw_cyclonedds). The part is here. (It should be added executor_.reset()) . I will send other backtrace logs after a detailed look. Let's wait your PRs.
