Out of Memory Issue

[MathNewBalance]

Hi,

I am a big fan of the plugin and its super useful. However I am getting an issue with the plugin eventually running out of memory despite clearing and deleting structures after use and then flushing pending deletes. I wondered if you could give me any advice on how to fix this

Best wishes

Hi @MathNewBalance!

Which operations do you use primarily? Would it be possible to create a simple repro with e.g a for loop that does the operations a 1000 times so we can easily figure out which functions to fix?

Best,

Erik

HI Erik,

Sorry for the slow reply, I have attached an example of the function I am running below. It runs every frame the mouse is moved over a canvas so been run pretty often

 UpdateOffset(MousePosition) {
        this.clearPolyTree();
        
        let i = 0;
        let v = 0;
        let OffsetedPath = undefined;
        let Distance = 0;

        
        this.SortPaths(MousePosition)
        this.OffsetingPaths.push_back(this.currentGraphic.path);

        for (i = 0; i < this.Graphics.length; i++) {
            try{
            this.OffsetingPaths.push_back(this.Graphics[i].path);
            }
            catch(err){
                console.log(err);
            }
        
        }
     
        for (i = 0; i < this.OffsetCount; i++) {
            Distance = this.OffsetGap * i;
            try{
            OffsetedPath = this.clipper2.InflatePathsD(this.OffsetingPaths, Distance, this.clipper2.JoinType.Miter, this.clipper2.EndType.Polygon, 100.0, 3, 5);
            }
            catch(err){
                console.log(err)
            }
            for (v = 0; v < OffsetedPath.size(); v++) {
                try{
                this.OffsetedPaths.push_back(OffsetedPath.get(v));
                }
                catch(err){
                    console.log(err);
                }
            }
            OffsetedPath.clear();
            OffsetedPath.delete();

        }

        this.ClipperObject.AddSubject(this.OffsetedPaths);
        this.ClipperObject.AddClip(this.ShapeBoundary);
        try{
            this.ClipperObject.ExecutePoly(this.clipper2.ClipType.Intersection, this.clipper2.FillRule.EvenOdd, this.PolyPath)
        }
        catch(err){
            console.log(err);
        }
        this.ClipperObject.Clear();
        this.ClipperObject.delete();
        this.FinalCount=  this.PolyPath.count();        
      
    }```

Do you also clear OffsetingPaths and destroy it? anything that is created in JS must be destroyed as well in JS.
Its hard to tell where the leak is coming from just looking at this.
