Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. contain some examples of rclcpp APIs in use. I believe that state_machine_ needs to be protected by mutex lock. a rclcpp::Subscription typically has shared ownership of two different rcl_subscription_t. when a message is received for the deleted subscription: a callback is called for the subscription the user has already deleted, [thread 1] user creates subscription and adds the node to an executor, [thread 1] at some point (for any reason) the executor loops and lets go of it's shared ownership of the, [thread 1 or 2] user deletes subscription, if in thread 1, that would be from within another callback, special consider would need to be given for deleting a subscription from within it's own callback, at this point, the executor is guaranteed to not be using the. I'm not sure I see why we need shared_ptr at all. Right, except we need to differentiate in the C++ class and the C rcl handle for the resource, e.g. I'm not sure I see why we need shared_ptr at all. I just went on a machine, did a clean install of ROS2 Foxy, installed nav2 / nav2 -bringup packages, and launched the TB3 simulation with and without the SLAM field.

A separate, but more completely (and more complicated) solution is to make it so that the destructors of our C++ classes force the executor(s) to give up shared ownership of the rcl_*_t classes before calling the equivalent rcl_*_fini() function on them and returning. to your account. Also I definitely agree with the need for an automated test around this. This suggestion is invalid because no changes were made to the code. The rcl_wait_set_t would need to be modified to use the weak_ptr so that when rcl_wait tries to access, it can lock to determine if the pointer is still valid or not. service_name, std::forward(callback), qos_profile, group); service_name, std::forward(callback), qos, group); std::shared_ptr, std::shared_ptr. I was working on a feature using rclcpp_lifecycle::LifecycleNode to declare a parameter when I noticed that the declare_parameter API on the lifecycle node interface does not include the ignore_overrides flag as does the version in rclcpp::Node.It seems that in addition to this, there are a handful of functions that have yet to be implemented in the lifecycle node. The PR in its current state artificially delays the destruction of the ROS2 subscriber to ensure that the 'finalized' pointer doesn't become invalidated until we're done with it, which somewhat violates the idea that the user is the owner and is managing the lifecycle of that subscriber.

This extension: Extends TimerBase and related classes to allow priority values to be assigned to instances of these classes. In order to All ROS nodes take a set of arguments that allow various properties to be reconfigured. Have a question about this project? The problem disappears if only one thread calls get_current_state function. Thus, the old Sick S300 Professional CMS as well as the new Sick S300 Expert are supported. Also, this might be a good candidate for using a rclcpp sub logger of the node's logger so that it appears as my_node.rclcpp rather than just rclcpp. So while waiting it needs to have a lock on it.

I think the logger names ought to be lowercase. rclcpp This repository contains the source code for the ROS Client Library for C++ package, included with a standard install of any ROS 2 distro. CHANGELOG I've made some comments inline to that effect. Instead if we replace the raw pointers with weak_ptrs, we can safely dereference within rcl_wait when the user resets a sub pointer while preservering user-driven ownership. The one thing I want to clarify is about having the SubscriptionBase::get_handle() return a shared_ptr. right. GitHub Gist: instantly share code, notes, and snippets. projectroot.test.rclcpp.test_time_source rclcpp.TestTimeSource.callbacks rclcpp.TestTimeSource.callback_handler_erasure. So basically the sequence would go like this: So the documentation for rclcpp::Subscription (specifically rclcpp::~Subscriptions) would say something like "on deletion, the subscription is scheduled for removal from the ROS graph and will be actually removed at some undetermined point in the future". Suggestions cannot be applied while the pull request is closed. This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. The tf2_ros interface, which pre-dates lifecycle nodes and the node interfaces in rclcpp, would need to be updated to take the "node interfaces" that it uses, which are the common element between Node and LifecycleNode.For example, maybe it should instead take a pointer to rclcpp::node_interfaces::NodeTopicsInterface and a pointer to an instance of rclcpp::node_interfaces . This would just abort any further transaction with ongoing transaction error or maybe a possibility (conditionvar) to wait. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. nitpick: remove unnecessary leading blank line, nitpick: minimize vertical whitespace and also avoid pure whitespace changes in pr's. Whether or not we use the shared_ptr to a C++ object or the rcl_* equivalent type, we still are adding the overhead of creating shared_ptr's each time we loop over wait, which will be quite a bit more expensive. Sorry @guillaumeautran, I'll get to it as soon as I can, I just have a lot of other stuff on my plate at the moment. Sorry for the delay in reviewing, I needed a block of time to wrap my head around the whole thing. Use #include "rclcpp/rclcpp.hpp" to access common elements of the ROS2 system.

This file contains bidirectional Unicode text that may be interpreted or compiled differently than what appears below. It seems that Rpr failure is not related to current PR. A tag already exists with the provided branch name. Isn't SubscriptionBase essentially the owner of the subscription_handle_ and all others are just observers, in which case the member itself would be of type std::unique_ptr and get_handle() would return std::weak_ptr? In which case I think it does need to return a shared_ptr and not a weak_ptr (though the caller could always upgrade the weak_ptr to a shared_ptr). If you want to rebuild ROS2 entirely, then run colcon build --symlink-install from your top-level ros2_ directory. It provides an implementation for both, the old (1.40) and the new (2.10) protocol. This is obviously not ideal, as the user would like to have some more determinism in how the shutdown of the subscription works. Have a question about this project?

Thank you @fujitatomoya for the work! To prevent an object from being deleted while the rcl_wait_set is This is because the executor scheduling thread is too busy to allow executable entities to run between blocking periods. rclcpp_lifecycle::LifecycleNode::get_current_state is not thread safe.

It's best to start a root shell before running your ROS2 application (e.g. Note: PPE doesn't work for services, or other waitable types besides timers and subscriptions. any opinion? 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 . // the updated robot state while inside of a ROS2 callback. Otherwise if no other changing/writing calls from other threads are allowed during the release of pre and reacquiring of cb or post, we can only unlock if other writing API calls recognize an ongoing atomic transaction (due to code in pre). However, it is not a trivial thing to do (in my opinion), since you need to avoid deadlocks and starvation (usually using a pair of mutex, of which one is a "barrier" mutex, e.g. I believe that state_machine_ needs to be protected by mutex lock. I do not see any such issues. You must change the existing code in this line in order to create a valid suggestion. The rcl_wait_set_t would need to be modified to use the weak_ptr so that when rcl_wait tries to access, it can lock to determine if the pointer is still valid or not. Created May 11, 2018. Having the node name as context would help you narrow it down. This extension: To use the PPE, you need to be building ROS2 from source. Cannot retrieve contributors at this time.

Looks like ros2/rcl#81 is closed, can you try replacing this TODO and code snippet with rcl_service_is_valid()? So basically I'm proposing that we decouple the C++ class and the rcl type, such that the user can only control when the C++ class is destroyed. Suggestions cannot be applied on multi-line comments.

By clicking Sign up for GitHub, you agree to our terms of service and Note: PPE needs to be run on a system with at least two cores. Here's my rationale why, consider this case (current behavior): The existing behavior, described in #349, this resulted in segfault's when rcl_wait was still using an rcl_* object, because that object had had it's _fini() function called on it from the destructor of one of our C++ classes. Regarding the node sublogger, shouldn't this be a rcutils concerns (as opposed to encoding the node name when writing the log)? for doing this, I think we need to change the API to return the object. std::chrono::duration period.

This file contains bidirectional Unicode text that may be interpreted or compiled differently than what appears below. Note: I've tested this change quite a bit with topic subscriptions and also used valgrind to track memory leaks. For example, here's a similar sequence of events as above: This would change the documentation of the classes, e.g. I also noticed the crash when concurrently invoking a lifecycle node state transition while at the same time the node was checking the current state.

Removing these not-necessary clearings of listener callbacks, since the objects are being destroyed anyway. Life cycle There are 4 primary states: Unconfigured Inactive Active Finalized To transition out of a primary state requires action from an external supervisory process, with the exception of an error being triggered in the Active state. Thanks for the pull request, but I think it needs a slight change of approach to work best. for doing this, I think we need to change the API to return the object. However, this is the simplest solution for the errors/segfaults (and what is implicitly happening right now). The other option is to provide an API impl to the callback that does not need to lock, but this would be a breaking change I guess. besides, probably we want to do this for user experience? std::map params.

Not doing that correctly will result in deadlocks, and might be just as bad as the current solution due to lock contention, but we wouldn't know which is better until we tested it in a few different scenarios. It is faster to simply specify the rclcpp package. There might be a better solution, which is more complicated but also more performant, which involves preventing the destructor from running until the executor is woken up and in between wait calls.
