There's something funky going on deep in mrml. I also get random test failures. The attached image shows a test failure in the MRMLCoreCxxTests.

While researching bug 0003752 I needed to save and reload a scene. Doing so led to an infinite loop trying to load the scene. When I did a force quit I got the following stack trace. I would say there is something wrong with the recent changes to the node reference handling.

Probably one of these commits didn't work as intended:

I have a debugging session that illustrates the crash in the mrml node test. I attached a picture and here is the stack trace:

I was also able to catch one of the failing python self-tests (py_AtlasTest) that has been timing out on the dashboard lately. Here's a stack trace from gdb on linux of where it is hung. Looks related to the issue on the mac and windows.

Thanks, Steve! This seems to be a real issue then.

The following topic fixes the issue.
See https://github.com/jcfr/Slicer/compare/3754-restore-mrml-reference-api-fix-py_SubjectHierarchyCorePluginsSelfTest

I am re-running all tests locally. Will integrate later this afternoon.

If you have a chance, would be great if you could also try the topic.

Humm .. false positive. Still need to investigate.

We agreed on phasing out assert() commands so that Slicer yields meaningful error messages (also to log files) and recover gracefully. Please do not add more of them.

+1 to the no assert comment.

Fixed in r23414
See http://viewvc.slicer.org/viewvc.cgi/Slicer4?view=revision&amp;revision=23414

The crash related to MRML reference has been fixed. The "new" stack trace has been uploaded as "3754-stacktrace-after-r23414.png", it possibly related to issue 0003714 and SlicerRt issue 598 [1]

// --------------------
BUG: Restore original behavior of vtkMRMLNode reference functions

This commit continues what has been started in r23395, it basically reverts
the logic handling reference to the implementation existing prior to r23192.

It reverts all the changes (r23192, r23196) that were done to be
able to set/get a reference at a position N. But it keeps:

• the readability improvements to complete successfully. (r23193)
• the transition to smart pointer simplifying the code (r23191)
• changes done as part of r23192 and this commit fixing the
  following tests:
  • py_AtlasTests
  • py_CompareVolumes
  • py_SlicerMRBTest
  • py_RSNAVisTutorial
  • py_VolumeRenderingSceneClose
  • py_Slicer4Minute

It fixes "py_SubjectHierarchyGenericSelfTest" crash that is reported in
issue 0003754 and was "related to MRML references. There are still one more
problem that is most likely related to the way SubjectHierarchySceneModel
deals with QModelIndex.
// --------------------
</pre>

There's still a timeout for the AtlasTests on today's dashboard. Do you think this is unrelated?

Just tried r23422 and still got a hang on windows running the py_CompareVolumes test. This was on windows and the hang happens when scene is closing and node references are being removed.

Hi Jc, have you reverted your commit for fixing n-th reference issue?
Do you want me to look at this issue? if so please re-assign it back to me.

@Alex: I reverted all changes related to "setting n-th" references.
See http://viewvc.slicer.org/viewvc.cgi/Slicer4?view=revision&amp;revision=23414

The only things I kept was the use of smart pointer.

Would be great if you could also have a look.

Thanks

Ideally, it would also be nice to re-factor "SetNthNodeReferenceID" [1] and "SetAndObserveNthNodeReferenceID" [2] to have a common logic, there is currently a lot of duplication which make the maintenance and bug fixing non-trivial.

There is an infinite loop in AtlasTests in the references code.
GetNumberOfNodeReferences() returns non zero after all references deleted using RemoveNthNodeReferenceID().

Thanks! I removed the workaround code and it crashes with the call stack below. It seems a node has been deleted before reaching this location, possibly incorrect reference counting.

I guess the issue related to "GetNumberOfNodeReferences()" has been fixed but their still problem related to the model index in the subject hierarchy. I suggest we re-assess when the following issue will be fixed:

https://www.assembla.com/spaces/slicerrt/tickets/598

The node reference issue seems to be gone - at last! Thanks for the hard work on this.

Agreed. I'm working on that ticket now anyway. Thanks for fixing the references!

Yeahh.

@Csaba: Thanks for working on this. Let me know if you would like to organize an other hangout with Julien.

Last night, also spend some time running valgrind on all MRMLCore test and will have few more patches fixing other memory issues.

The lessons learned ...

(A) before integrating some major changes (related to the MRML references), in addition to talk about it on the mailing list [1], keep a long running branch on the side and test exhaustively.

[1] http://slicer-devel.65872.n3.nabble.com/MRML-References-update-proposal-td4031425.html

(B) if you see two functions, doing almost the same thing:

Code 1:

[...]
reference->ReferencedNode = 0;
//reference->SetReferencedNodeID("");
reference->SetReferenceRole(referenceRole);
[...]

Code 2:

[...]
reference->ReferencedNode = 0;
reference->SetReferencedNodeID("");
reference->SetReferenceRole(referenceRole);
[...]

=> do not assume, the line was commented by "mistake", even if blaming the file give you no hints. [2]

Fixed in http://viewvc.slicer.org/viewvc.cgi/Slicer4?view=revision&amp;revision=23505

Thanks.

Was in resolved status for two years, no more comments since the fix, so closing.
