Memory leak in Simulation.unload() caused by collision pipeline #3318

ScheiklP · 2022-09-21T09:17:53Z

Problem

Hi,
I discovered a memory leak that seems to be connected to the collision detection pipeline / models.

The scene contains 2 nodes with MechanicalObject and PointCollisionModel.
I repeatedly load and unload the scene, first with no collision models, then one collision model, and then two collision models.
-> each graph has 3 segments.

import Sofa
import Sofa.Core
import Sofa.Simulation
from enum import Enum


class TestCase(Enum):
    ONE_MODEL = 0
    TWO_MODELS = 1
    NONE = 2


class SimulationHandler:
    def __init__(self):

        self.root_node = Sofa.Core.Node("root")
        self.nodes = createScene(self.root_node, TestCase.NONE)
        Sofa.Simulation.init(self.root_node)

    def step(self):
        Sofa.Simulation.animate(self.root_node, self.root_node.getDt())

    def reload(self, case: TestCase = TestCase.NONE):

        Sofa.Simulation.unload(self.root_node)
        self.root_node = Sofa.Core.Node("root")
        self.nodes = createScene(self.root_node, case)
        Sofa.Simulation.init(self.root_node)


def createScene(root, case: TestCase):
    plugins = [
        "Sofa.Component.Collision.Detection.Algorithm",
        "Sofa.Component.Collision.Detection.Intersection",
    ]
    for plugin in plugins:
        root.addObject("RequiredPlugin", pluginName=plugin, name=plugin)

    root.addObject("DefaultAnimationLoop")
    root.addObject("DefaultPipeline")
    root.addObject("BruteForceBroadPhase")
    root.addObject("BVHNarrowPhase")
    root.addObject("DefaultContactManager")
    root.addObject(
        "LocalMinDistance",
        alarmDistance=5.0,
        contactDistance=0.5,
    )

    node_1 = root.addChild("child_1")
    node_1.addObject("MechanicalObject", position=[0, 0, 0] * 5)

    node_2 = root.addChild("child_2")
    node_2.addObject("MechanicalObject", position=[1, 1, 1] * 5)

    if case == TestCase.ONE_MODEL:
        node_1.addObject("PointCollisionModel")
    elif case == TestCase.TWO_MODELS:
        node_1.addObject("PointCollisionModel")
        node_2.addObject("PointCollisionModel")
    elif case == TestCase.NONE:
        pass

    return node_1, node_2


if __name__ == "__main__":
    simulation = SimulationHandler()

    for i in range(5000):
        simulation.step()
        simulation.reload(case=TestCase.NONE)

    for i in range(5000):
        simulation.step()
        simulation.reload(case=TestCase.ONE_MODEL)

    for i in range(5000):
        simulation.step()
        simulation.reload(case=TestCase.TWO_MODELS)

No components of the collision pipeline:

-> No memory increase, even with two collision models

NewProximity

-> Some memory increase with one and no collision models, STRONG increase with two collision models

LocalMinDistance

-> Some memory increase with one and no collision models, STRONG increase with two collision models

As you can see, there is a memory increase with no collision models and one collision model,
but with two collision models, the increase is much stronger. This is why I suspect the leak is somewhere in the pipeline, not the
collision models themselves.

I guess @damienmarchal and @hugtalbot would be the right people to annoy with another leak. :D

Could this be caused by DefaultPipeline, BruteForceBroadPhase, BVHNarrowPhase, and DefaultContactManager not having a proper reset() function?

damienmarchal · 2022-09-21T20:25:58Z

Thanks again @ScheiklP for these investigations !

Normally the reset function is not supposed to have any cleanup results as it is only there to set again (re-set) the component in a previous state.

It is the "cleanup" that is called before removal/deletion of the component from the graph.

Most of these components also do not have a cleanup function :D

I adapted the sofaProjectExample to match the python scene above to make memory profiling and debugging a bit easier. Same memory leak occurs.

I echo @damienmarchal , thanks a lot @ScheiklP for these interesting investigations!

your last comment means that it could come from the collisionmodel binding, right?

alxbilger · 2022-09-22T07:19:16Z

I don't know this part of the code, but it is highly suspicious:

https://github.com/alxbilger/sofa/blob/918cd66008f586575c92c1e068f5c267a952b936/Sofa/framework/Core/src/sofa/core/collision/IntersectorFactory.h#L95

    virtual void addIntersectors(TIntersectionClass* object)
    {
        new TIntersectorClass(object);
    }

addIntersectors (in which there is a new call), is called in the constructors of the proximity intersections (BaseProximityIntersection). I cannot find if this allocation is freed somewhere.

Thanks @alxbilger ! :)

I have a commit here, that puts the created pointers into a map, so that they get cleaned up, if they are created multiple times.
master...ScheiklP:sofa:fix_unload_memory_leak
But it does not fix the leak.

What do you think? Should this still be a PR?

Hi @hugtalbot ,
The collision models have no explicit binding in SofaPython3 as far as I can see. :(

EDIT:
I was just not creating the MechanicalObject correctly. :D -> C++ scene also has the leak.

I don't know enough this part of the code to answer you. For sure it sounds better, but I advise more investigations.
Anyway, it's not the leak we are looking for.

damienmarchal · 2022-09-23T09:43:06Z

Thanks again for the investigation.

I see you are using the raw c++ code to make your scene. Instead of doing that the "hard way" you can use "simplapi" which mimick in c++ de python one. It is in sofa/simulation/graph/simpleapi.h and there are exemple in the code base.

Does this not look suspicious to you guys?

@damienmarchal @alxbilger @ScheiklP

Indeed it does. :D
I did some quick checks by printing a string, when the deconstructor of that class is called, and it seems to get deleted somewhere correctly. :)

hugtalbot · 2022-09-23T14:16:17Z

alright ;) I quickly search for new in the collision repo!

alxbilger · 2022-09-23T14:18:29Z

@ScheiklP Here is a branch with a simple object tracker: https://github.com/alxbilger/sofa/tree/objecttracker

It counts the number of creation and destruction for each class managed with the SOFA_CLASS macro. Note that if Y derives from X, it counts both X and Y. Finally, it prints a summary when the program finishes (properly). But I cannot guarantee that more destructions does not happen after the summary (static destruction order depends on construction order and https://en.cppreference.com/w/cpp/language/siof). Is this useful to you? Can you spot which component is not destroyed?

The diff is here: https://github.com/sofa-framework/sofa/compare/master...alxbilger:sofa:objecttracker?expand=1

For example, there are a couple of components in caduceus where I see a difference between nb of allocations and destructions.

So that looks ok, right? At least the difference is more or less constant. :D
But the tracker only tracks actual objects, right? So Creators, Factories, and others that do not inherit from base are not tracked.

Could it be a vector/map that constantly receives new values but is not cleanup up with reset/cleanup?
Similar to what was happening in sofa-framework/SofaPython3#304

alxbilger · 2022-09-23T14:48:35Z

I don't think so because components are destroyed in the unload

At least now we know that there are no leak in the components themselves. The track continues

Sounds like createOutputModel is a good first spot to look at as it allocate an output vector with new... and that this one is returned to finally be stored in a map (eg: line 50 in NarrowPhaseDection).... which is not deleted when destructing object.

I suggest using the memory sensitization tools provided by GCC or Clang - it is less hassle than valgrind. It also provides more detail regarding memory leaks.

To do this, build Sofa with the additional flag: cmake .. -DCMAKE_CXX_FLAGS="${CMAKE_CXX_FLAGS} -fsanitize=address"

Here is the output when running the example (CPP) scene provided by @ScheiklP.

The 15 object(s) that are detected are come from the number of unloads performed (I decreased it to 15 from the original 1000 used in the scene by @ScheiklP)

At the moment it looks like the object created here src/Sofa/framework/Core/src/sofa/core/collision/Intersection.h line 48 is never deleted.

void NarrowPhaseDetection::endNarrowPhase()
{
    for (auto it = m_outputsMap.begin(); it != m_outputsMap.end();)
    {
        DetectionOutputVector *do_vec = (it->second);
        if (!do_vec || do_vec->empty())
        {
            if (do_vec)
            {
                do_vec->release();
            }
            m_outputsMap.erase(it++);
        }
        else
        {
            ++it;
        }
    }
}

The intended behavior of this is "if the vector is empty, or it's a nullpointer, remove it from the map. If it is not a nullpointer, also release the vector", right?

Since the do_vec->clear() is in beginNarrowPhase, the vector is never released correctly.

It was indeed the TDetectionOutputVector* but in a completely different location than expected. :D
