Re: [cdt-dev] Recursive DSF view model nodes in the debug view

Hi Dobrin,
I'm sorry I haven't had time to look at this, could you create a bug with your patch so it doesn't get lost?

Thanks!

Thanks Pawel for the pointers.

I’ll follow them for my recursive container.

 

BTW,

I think the Windows version of FileVMNode.java needs slight adjustment to handle the multiple drives case.

You can see if the attached patch makes sense.

Without the patch pasting a path will expand all drives (root nodes) instead of one.

 

May be there is a better fix than this patch?

See how all drives are included in the delta when I paste “C:\Program Files\Adobe”.

How can I make sure that only C drive is included in the delta?

 

Thanks

Dobrin

Hello,

Has anyone tried recursive view model hierarchy in the debug view using DSF?

Yes, you can even look at org.eclipse.cdt.examples.dsf.filebrowser for an example ;-)
It's a simplistic example though, so you may uncover new bugs in this area.

I’d trying something like

launch

            container

                        thread

                                    stack frame(s)

            container

            container

                        container

                                    container

                                                thread

                                                            stack frame(s)

                        container

                                    thread

                                                stack frame(s)

                       

It does show up properly in the debug view.

But when I fire suspended event on the thread for some reason my StackFrameVMNode.buildDelta doesn’t get called even though its getDeltaFlags returns properly CONTENT + EXAPND + SELECT for ISuspendedDMEvent.

I’ll keep digging into DefaultVMModelProxyStrategy code tomorrow.

I just saw a comment “Avoid descending into recursive node hierarchy's when calculating the delta.” and decided to make sure I am not trying a use case that is not supported by design.

What this means is that if you have a recursive hierarchy (i.e. a node that has itself as a child), then this node is responsible for building a delta with all the levels in this hierarchy.  For example, in the hierarchy you have above when the container node is called, it needs to build a delta for all the nested containers before it completes so that the thread vm node can build on top of that.

 

 

Hope this helps,
Pawel

In other words, when the ContainerVMNode.buildDelta() is called it needs to

Thanks in advance!
