Executor.spin_until_future_complete() assumes spin_once() returns when the work has been completed. Have a question about this project? Get AccuWeather alerts as they happen with our browser notifications. Pay attention to the mosquito or pest forecast and prepare deterrents. Wrap rclcpp::Node with basic Lifecycle behavior? Instead, I would prefer having the application developer define the strict minimum amount of threads (with 2 by default) for reproducible results. Have a safe trip. The subnode receives the message, sets the future as complete, but the exe.spin_until_future_complete(future_msgs) never returns. Indeed, the normal user will use the default Multi-threaded executor which would spin 128 threads on a Threadripper machine for each executor. This ensures the number of threads of a Multi-threaded executor is at least 2 unless defined explicitly as 1 (why not use the SingleThreadedExecutor?) You signed in with another tab or window. I guess this all comes down to better understanding the spinning process / callback queues and multi-threading of ROS2. By voting up you can indicate which examples are most useful and appropriate. has a nice explanation for the SingleThreadedExecutor (default) and MultiThreadedExecutor next to the use of callback groups in ROS2. The reason will be displayed to describe this comment to others. it's been fixed with current master, i am not sure #585 (comment) comments. MultithreadedExecutor.spin_once() and Executor.spin() assume spine_once() returns when work has been dispatched, but not necessarily completed. Conditions for golfing are poor. Or has the fix been in any release? Indeed, the normal user will use the default Multi-threaded executor which would spin 128 threads on a Threadripper machine for each executor. Already on GitHub? MultiThreadedExecutor spin_until_future complete should not continue waiting when the future is done, MultiThreadedExecutor spin_until_future complete should return once future is done, MultiThreadedExecutor:spin_until_future_complete can block when the f, https://github.com/fujitatomoya/ros2_test_prover/blob/master/prover_rclpy/src/rclpy_585.py, Publish a message from one node (with latching_qos), In another node, subscribe to the topic with a callback that sets the result of the future. Learn more. Sign in #605 is a proposed fix. Conditions for cycling are poor. Besides this, the change looks good to me. If I understand correctly, it looks like there are conflicting assumptions in Executor about when spin_once() returns. Run a node which is running a practically _forever_ loop. btw, setting the timeout for spin_until_future_complete will avoid this problem. number_of_threads_ = number_of_threads ? In the project that this was causing issues for me, I have just switched to the SingleThreadedExecutor and that has solved my problem, but I will need to use the MultiThreadedExecutor later on. That's now being turned into a guide: ros2/ros2_documentation#2652. Indeed, if we are calling a service from a callback and call the get function of the future directly, we effectively block until the service request resolves but it can't as the reply will not be processed, causing a deadlock. The future does get completed, as the add_done_callback(lambda fut : print("Future is done")) gets triggered, so I don't think future does not get completed is suitable. The risk for pest activity is high. We have updated our Privacy Policy and Cookie Policy. However, sensitive groups may experience minor to moderate symptoms from long-term exposure. rviz2 does not show the images published on the topic, Best way to integrate ndarray into ros2 [closed], ROS2 how to do multi-threading, subscription callbacks, spinning , executors, Creative Commons Attribution Share Alike 3.0. This suggestion is invalid because no changes were made to the code. spin_until_future_complete with timeout could be a work-around for now. Well occasionally send you account related emails. This is NOT deadlock issue, main thread is just waiting via rcl_wait. Please start posting anonymously - your entry will be published after you log in or create a new account. the fix has been backported to foxy and galactic(atm, this was mainline), so it should be fixed. The use of std::thread::hardware_concurrency also bothers me. Sign up for a free GitHub account to open an issue and contact its maintainers and the community.

You signed in with another tab or window. Can I put the main loop on a rate or something so that the spin procedure can run as intended? By voting up you can indicate which examples are most useful and appropriate. thanks for the fix! I seem to be running into a similar issue here. but i cannot reproduce this problem in thousand times with while true; do ros2 run prover_rclpy rclpy_585; done. Thank you for finding the cause. There was a problem preparing your codespace, please try again. 2021 AccuWeather, Inc. "AccuWeather" and sun design are registered trademarks of AccuWeather, Inc. All Rights Reserved. Have a question about this project? i think this is the problem titled with future does not get completed? This is either solved by having a Multi-threaded executor and multiple callback groups for non time critical software (which has to wait for the result anyway). Please Where can I read more about this? future is actually done set_result by executor.submit(callback) but before future gets set_result, main thread will call spin_once(). Was this ever fixed? Wear long-sleeved shirts and pants when spending time outdoors to prevent bites. Have the node receive subscription callbacks succesfully. The default number of threads is std::thread::hardware_concurrency which can be 1 for a VM or a small target. Hi/Low, RealFeel, precip, radar, & everything you need to be ready for the day, commute, and weekend! In the multithreaded executor, I don't think there's going to be a way to make spin_once() return when work has been completed, thus I've tried to add a mechanism to wake up the executor and make it check the future state again. Work fast with our official CLI. privacy statement. @fujitatomoya Sorry for the late reply, I have been on annual leave and took a break from all coding. A tag already exists with the provided branch name. To review, open the file in an editor that reveals hidden Unicode characters. Another attempt was made as follows (see below), here am using threading in a raw manner, which also seems to "work" but also seems very rough around the edges. This means those targets (or VM) will not be able to receive the message of an otherwise correct node, while working on everybody else's machine. The check for if (number_of_threads_ == 0) has been replaced for the check if (number_of_threads_ == 1) to output a warning. Contribute to ros2/rclpy development by creating an account on GitHub. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. is this actually deadlock you found? The use of std::thread::hardware_concurrency also bothers me. This suggestion has been applied or marked resolved. Instead, I would prefer having the application developer define the strict minimum amount of threads (with 2 by default) for reproducible . The second motivation is to solve the misconception a Multithreaded executor always has multiple thread, by making it have always multiple treads by default. The risk of dust and dander symptoms is extremely high. This seems reasonable to me (though I'm going to update the title; we aren't setting the default to 2, we are setting the minimum to 2). This rcl_wait will never be fired with this sample program, because there is nothing to do and timeout is not set either. MultiThreadedExecutor should use assigned CPUs in the process space if possible. ROS Client Library for the Python language. Conditions for lawn mowing are poor. Only one suggestion per line can be applied in a batch. So, it clear to me that I need a better understanding of what is happening under the hood with ROS2. Eliminate standing water in rain gutters, buckets, and in tires where pests can breed. Have the node receive subscription callbacks succesfully. Already on GitHub? import threading import rclpy rclpy.init() node = rclpy.create_node('simple_node') # spin in a separate thread thread = threading.thread(target=rclpy.spin, args= (node, ), daemon=true) thread.start() rate = node.create_rate(2) try: while rclpy.ok(): print('help me body, you are my only hope') rate.sleep() except keyboardinterrupt: pass Only swim in water temperatures below 55 degrees if you have the proper gear. An attempt was made by me here and I "solved" that (read: made it work . The risk of suffering from a weather-related migraine is low. @fujitatomoya only in master? Is there not a way of passing through the cancelled signal to the future, raise a capturable cancelled signal. If nothing happens, download GitHub Desktop and try again.

You must change the existing code in this line in order to create a valid suggestion. Conditions for driving are good. The subnode should receive the message, set the future as complete, and then the program should exit. Here is the code for the node defined in that workspace. MultiThreadExecutor number of threads is at least 2+ in default. Then it waits on rcl_wait for the next ready event. Fast-RTPS Client library (if applicable): rclpy Publish a message from one node (with latching_qos) In another node, subscribe to the topic with a callback that sets the result of the future Start both nodes in a MuliThreadedExecutor Spin until future complete If you suffer from dust and dander allergies, taking allergy medication can help relieve symptoms. i may be missing something, I'd like to hear from the others. As @fujitatomoya explained here, there's no deadlock. Set the default number of threads of the MultiThreadedExecutor to 2. As on how to fix it, I am not sure sorry, I'm still very unfamiliar with the codebase. As I understand it, ROS1 multi-threading was implicit. I've been trying to find the convention for ROS2 of solving the following, relatively simple problem: An attempt was made by me here and I "solved" that (read: made it work - doesn't seem like the correct way) by forcing a call to rclpy.spin_once() inside the loop in (1). If nothing happens, download Xcode and try again. IMO, custom executor should define spin_impl() but spin_once(). Clarity: Use a comparison operator as number_of_threads is a number. I understand this is a non-issue for power-users which will manage themselves the single executor for the app or use composition, but it will avoid a whole range of issues. @craigh92 @fujitatomoya it would be great if you can confirm that the proposed fix solves the issue in the posted example, thanks! Parameters MultithreadedExecutor.spin_once() and Executor.spin() assume spine_once() returns when work has been dispatched, but not necessarily completed. Suggestions cannot be applied while viewing a subset of changes. Conditions for flying are great. For building documentation, you need an installation of ROS 2. Here's what happened, The 'Blue Marble': One of Earth's most iconic images, 50 years on.

Conditions for running are poor. to use Codespaces. i am not sure how to fix it, any thoughts? Plus, for computation intensive software (reentrant data callbacks to start multiple long processing, maybe for CV), a user option to set the number of threads higher would be great (in that case as the number of cores). to your account. That problem shows up here because the future.done() check in Executor.spin_until_future_complete() assumes the subscriber callback from the last spin_once() call has been completed, but it's actually only been dispatched. Stay out of the water if there is a chance of lightning. For the yield_before_execute option, when true std::this_thread::yield()will be called after acquiring work (as an AnyExecutable) and releasing the spinning lock, but before executing the work. Are you sure you want to create this branch? Thank you for your patience as we work to get everything up and running again. The risk for pest activity is extremely high. Minor: number_of_threads is a size_t, not a boolean, so prefer doing an explicit check with number_of_threads > 0.

Lightening and extremely cold temperatures are unsafe for outdoor runners. sign in (https://github.com/fujitatomoya/ros2_test_prover/blob/master/prover_rclpy/src/rclpy_585.py). The text was updated successfully, but these errors were encountered: confirmed the problem with rclpy::MultiThreadExecutor. Source your ROS 2 installation, for example: This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. I've updated the PR title accordingly. CI is happy here, so going ahead with this. As I understand it, ROS1 multi-threading was implicit. This file contains bidirectional Unicode text that may be interpreted or compiled differently than what appears below. This is useful for reproducing some bugs related to taking work more than once. It is very similar to the code posted in this bug report, but with a few argparse options. What is the correct way of multi threading in ROS2? That is a very informative resource, thank you very much. The risk of weather-related sinus pressure is low. Try searching for a city, zip code or point of interest. if you still see the issue, please create another issue with reproducible sample. but the problem still can be observed when we use MultiThreadedExecutor. (aka what I just had, someone having a deadlock for a software which works for everybody else). Suggestions cannot be applied from pending reviews. I would add a warning / error /something if a user tries to set the number of threads of this executor to 1. Executor.spin_until_future_complete() assumes spin_once() returns when the work has been completed. Here are the examples of the python api rclpy.executors.MultiThreadedExecutor taken from open source projects. number_of_threads : std::thread::hardware_concurrency(); Add this suggestion to a batch that can be applied as a single commit. Use Git or checkout with SVN using the web URL. In fact, if you used a multi threaded executor to load one or more component nodes (again nodes implemented as a sub class of rclcpp::Node ), then you're using most of the things you listed: composition, MultiThreadedExecutor, std::thread, and pthread (because std::thread is probably implemented with pthread on your machine). Avoid outdoor activity if there is a chance of lightning or in extremely cold temperatures. Do not play if there is a chance of lightning. What is the correct way of multi threading in ROS2? rclpy (ROS Client Library for Python). I will need to use the MultiThreadedExecutor later on. I'll take any resources that can help out here as I've been looking around and while there is bits and pieces, I cannot find a comprehensive piece of code or documentation that paints the full picture. Successfully merging a pull request may close this issue. Sign in Well occasionally send you account related emails. (. I'm running latest galactic release and I have a service that waits for a future which is set by a subscriber, that arrives in the next couple of seconds, and it deadlocks. Suggestions cannot be applied while the pull request is closed. That problem shows up here because the future.done() check in Executor.spin_until_future_complete() assumes the subscriber callback from the last spin_once() call has been completed, but it's actually only been dispatched. I have also asked a question on ROS Answers here. Add pytest.ini so tests succeed without warnings when run locally. Semarang (Javanese: , Pegon: ) is the capital and largest city of Central Java province in Indonesia.It was a major port during the Dutch colonial era, and is still an important regional center and port today.The city has been named as the cleanest tourist destination in Southeast Asia by the ASEAN Clean Tourist City Standard (ACTCS) for 2020-2022. If I swap this out for the SingleThreadedExecutor then it works as expected. I've been trying to find the convention for ROS2 of solving the following, relatively simple problem: Run a node which is running a practically _forever_ loop. I'll run CI on it next.
