[Paraview] Where do I send Xdmf bugs/patches?

[Biddiscombe, John A.]

Dominik,

General consensus was that the Xdmf library was not very consistent in the way it was written -specifically when XdmfGeometry/Topology/other objects were created, some sub-objects were owned/parented and others simply referenced and when complex hierarchies of these objects were being used (as it typical in something like the vtk-reader/writer classes), it because difficult to manage things well and cleanly and know who was responsible for deleting things. leading to a lot of crashes and memory leaks if you got it wrong (and quite a lot of duplicated checks on objects too, but that's an aside).

The Xmdf chaps have completely rewritten the library using a much nicer C++ type approach using smartpointers etc and this means the API has changed significantly. The XML part remains essentially the same.

I would like to stop using the rather crufty Xdmfs in paraview (which you keep finding bugs in - and so do we - and nobody is supporting) and instead incorporate the new Xdmf into paraview (via the reader).

[We've got cool stuff like the XdmfGenerator which would go nicely with the new Xdmf too].

etc etc.

JB

Aparently my mail did not make it to the list, so I will repeat.
Please see below:

I was referring to Xdmf2 subfolder in PV git clone that I did following "users start here" wiki page. Is git://public.kitware.com/Xdmf2.git still something else? I am quite confused... Is it all explained somewhere on a wiki page?

What are the objectives of this branch and how will it be related/synced/contributed to the other branches? I am interested to join Xdmf development provided that this would have a solid future, like in VTK or Paraview.

Thanks and best regards,
Dominik

I can not even find anymore where the official repo is, the one found by google on http://www.xdmf.org/index.php/Get_Xdmf seems to point to some abandoned version.
