ros2: rqt --list-plugins sometimes segfaults #182

Closed wjwwood closed 5 years ago

wjwwood commented 5 years ago

I'm testing a ROS 2 Crystal release candidate on macOS (building from source), and I sometimes get:

$ rqt --list-plugins
rqt_console.console.Console
rqt_msg.messages.Messages
rqt_plot.plot.Plot
rqt_publisher.publisher.Publisher
rqt_py_console.py_console.PyConsole
rqt_service_caller.service_caller.ServiceCaller
rqt_shell.shell.Shell
rqt_srv.services.Services
rqt_top.top_plugin.Top
Segmentation fault: 11

I've been trying to reproduce it in the debugger, but I haven't been able to do so thus far. I'll keep trying for that or a core file.

Also, in the debugger I get this, though I don't know if it's related or even in rqt (maybe inside PyQt?):

Adding --force-discover makes it more reliable, here's the crash report from macOS:

It may be a bug in rclcpp or rclpy that's just being exposed in rqt, or may be something wrong with how rqt is mixing C++ and Python, not sure. I just wanted to get the details down.

dirk-thomas commented 5 years ago

@brawner Can you please try to reproduce the problem? I can't reproduce it on Ubuntu.

brawner commented 5 years ago

I'm rebuilding currently, I'll try to reproduce.

For reference, --list-plugins is passed through to qt_gui. https://github.com/ros-visualization/qt_gui_core/blob/4b22f7a4a482565c94399c0f704b0612f61bec5a/qt_gui/src/qt_gui/main.py#L497

If it prints out a list though, then the segfault is happening on exit. https://github.com/ros-visualization/rqt/blob/31af4cf6757a4485f07d94f030667f284fdff9e0/rqt_gui/src/rqt_gui/main.py#L87

brawner commented 5 years ago

I'm not able to reproduce the issue. Sometimes on Mac I run into segfaults on different versions of Python depending on when/where it was built. I'm using the version installed by homebrew.

I'm running 10.13.6. This is the header printed out when running python3

Python 3.7.1 (default, Nov  6 2018, 18:45:35)
[Clang 10.0.0 (clang-1000.11.45.5)] on darwin
wjwwood commented 5 years ago

I don't have any reason to believe it has anything to do with the Python version, but instead it's likely due to differences in threading on the two OS's. Though the version of Python may be influencing that as well, I just don't think it's likely myself. Try running stress on your computer at the same time to shake up the scheduling.

The backtrace clearly shows it is failing in Py_Exit, so on Python's shutdown (probably unloading a C++ based library, maybe an atexit() or __del__ in rqt) and then it's destructing the singleton signal handler in librclcpp which is trying to log a message when uninstalling the signal handler, and then fails because logging is already shutdown or something.

The logging failing during the destructor of the signal handler is almost certainly a bug, but it's not the root issue, just an issue while reporting the actual problem.

So it's either a bug in rclcpp (quite possible as that code has recently been changing) or a bug in how rqt is using rclcpp, e.g. maybe it is not doing init/shutdown in the right order or the right number of times or maybe it has something to do with mixing signal handlers up. rclpy and rclcpp may be both are setting up signal handlers and unloading them in different orders, and there there's the Python signal handler... could be messy.

brawner commented 5 years ago

I'll try the stress test, also I may need to make sure all of ros-visualization is built before I test as well. It sounds like it may be the rqt_gui_cpp nodelet_plugin_provider.

What plugins are actually installed on your machine? Do they match the list that's generated? rclcpp is currently only used by rqt_image_view and rqt_gui_cpp. If removing those two packages from your install directory and running --list-plugins doesn't segfault then it's very likely how rqt_gui_cpp creates and destroys the node.

We had to add code into rqt_gui_cpp to create a node and spin it in a separate thread. If rqt isn't using rclcpp correctly, then I would suspect it's in there.

Does this destructor look right? https://github.com/ros-visualization/rqt/blob/31af4cf6757a4485f07d94f030667f284fdff9e0/rqt_gui_cpp/src/rqt_gui_cpp/nodelet_plugin_provider.cpp#L51-L55

brawner commented 5 years ago

I'm now reproducing the issue. For me, 'sometimes' is about 50% when using --force-discover. Removing rqt_gui_cpp from install resolved the issue. @mlautman looks like this is a threading issue in rqt_gui_cpp, do you have any thoughts?

wjwwood commented 5 years ago

@brawner I don't have cycles to look at it right now, but I can at some point.

mlautman commented 5 years ago

@wjwwood @brawner It looks like the default spin methods aren't threadsafe. I'm not sure if it is related to this issue, but rqt_gui_cpp definitely needs a similar fix to this: https://github.com/ros-visualization/rqt/pull/184. I've been looking into it but I'm at a loss for how we should implement a solution here. While it would be trivial to pass the class encapsulating the executor around and add subscriptions to be destroyed to a queue, this requires that every plugin developer knows to do this. I have been looking through the rviz2 code and it seems they are locking the nodes before adding or removing subscriptions. Is this sufficient? Do you have any other documentation I can reference for this?

wjwwood commented 5 years ago

It looks like the default spin methods aren't threadsafe.

In which client library?

Also, spin should not be called from multiple threads, it actually doesn't make sense. But I guess you mean not thread-safe with other activities? In rclcpp they should be. I can't say for rclpy off-hand, but I'd recommend coming up with a small example that exihibits the problem, then open an issue on rclcpp/rclpy, at which point we can say if it's a bug or an invalid use case which we should document.

Unfortunately, there's not a lot of documentation for these functions or special cases like these.

I have been looking through the rviz2 code and it seems they are locking the nodes before adding or removing subscriptions.

Please link to the code you're talking about. AFAIK, it should be fine to let subscriptions go out of scope concurrently with spin, and so the locking may be for some other reason.

brawner commented 5 years ago

@wjwwood Here is an example with rclpy. You can't destroy a subscription from a separate thread while a node is spinning.

https://github.com/ros-visualization/rqt/issues/181

Proposed PR that addresses the issue https://github.com/ros-visualization/rqt/pull/184

wjwwood commented 5 years ago

Where is the example? I don't see one in either the issue #181 or the pr #184.

This was an example illustrating this issue with rclpy. rqt_gui_py creates a single node that is shared among python plugins (and similarly rqt_gui_cpp for c++ plugins). If an rqt plugin wants to subscribe to topics, it creates the subscription in its own code and on shutdown destroys it. If node.destroy_subscription() is called while the node is in spin_once, it will crash.

wjwwood commented 5 years ago

Sorry, I was looking for a trivial python script that exposes the issue. Without a trivial example, it's hard to rule out some other influence related to the architecture of rqt. (something like this: http://sscce.org/)

brawner commented 5 years ago

@wjwwood follow up here https://github.com/ros2/rclpy/issues/255

mlautman commented 5 years ago

RViz2 creates a wrapper around the node it passes into each of the plugins https://github.com/ros2/rviz/blob/ros2/rviz_common/include/rviz_common/ros_integration/ros_node_abstraction.hpp

These plugins then lock the node before calling methods on the underlying node. https://github.com/ros2/rviz/blob/0c7145448b4bd47a022fa8957d6c25bfcf07174a/rviz_default_plugins/src/rviz_default_plugins/displays/camera/camera_display.cpp#L283

In which client library?

I think this is what made me think that spin() might not be threadsafe. https://github.com/ros2/rclcpp/blob/69d7e69957a63487e07db01831082a8adcd14968/rclcpp/include/rclcpp/executor.hpp#L194

Athough, now that I am looking at it again, maybe spin() is threadsafe? As you mentioned, these methods aren't really documented so any hints here would be great.

wjwwood commented 5 years ago

All of the spin like functions should be run mutually exclusively. Spin like functions should be thread-safe in that it will fail if you call it from two different threads, e.g. spin_once() will fail if you call it concurrently: https://github.com/ros2/rclcpp/blob/eb2081bb25867da932a6c09b7729aced4f5f182e/rclcpp/src/rclcpp/executor.cpp#L237

The design of rclcpp means that "deleting" things like subscriptions and even nodes should be safe to do concurrently with spin functions. This is done by letting the shared pointer to these resources go out of scope. The executor holds a weak pointer to these things and converts those into shared pointers while spinning on them.

dirk-thomas commented 5 years ago

Assuming this has been resolved by ros2/rclpy#318 I am closing the ticket.
