T88334: Failure to preserve vertex groups through Geometry Nodes, new to 2.93
T88951: Move vertex group names from object to geometry

Commits

rB3b6ee8cee708: Refactor: Move vertex group names to object data

Summary

This commit moves the storage of bDeformGroup and the active index
to Mesh, Lattice, and bGPdata instead of Object.

As explained in T88951, the list of vertex group names is currently
stored separately per object, even though vertex group data is stored
on the geometry. This tends to complicate code and cause bugs,
especially as geometry is created procedurally and tied less closely
to objects.

The "Copy Vertex Groups to Linked" operator is removed, since they
are stored on the geometry anyway.

This patch leaves the object-level python API for vertex groups in place.
Creating a geometry-level RNA API can be a separate step, the changes
here are invasive enough as it is.

Share implementation of vertex group retrieval

Looks all very straight forward, good job!
Got a few minor comments, but those should be easy to fix.

Ideally at least one other dev should have a quick look at this. Also maybe @Demeter Dzadik (Mets) can check if this breaks production files?

source/blender/blenkernel/intern/deform.c
537	Implement this in terms of `BKE_id_defgroup_list_get`.
584	This and the function above can share code by extracting a `int *BKE_object_defgroup_active_index_p(...)` function.
source/blender/blenkernel/intern/lattice_deform.c
367	Can just cast to `ID *` directly.
source/blender/blenkernel/intern/mesh.c
935	Under what circumstances is this copied already? Would it make sense to always clear and copy the list?
source/blender/editors/gpencil/gpencil_fill.c
1526	Could you use `tgpf->gpd->...` directly?
source/blender/editors/object/object_vgroup.c
2846–2848	Don't call `BKE_object_defgroup_active_index_get` twice.
source/blender/makesdna/DNA_object_types.h
61	Reminder that there is this todo comment. I don't think it's super urgent to move this now. If you wanted to move it, you'd probably have to move it to a new file.
283	Leave a comment saying this has been moved to the object data.

This revision is now accepted and ready to land.Jul 5 2021, 6:21 PM

Safer RNA object vertex group API (should fix issues reported by @Demeter Dzadik (Mets), thanks!)

Hans Goudey (HooglyBoogly) added inline comments.

source/blender/blenkernel/intern/mesh.c
935	The newly added `BKE_id_eval_properties_copy` function does this. The correct thing to do is free the list and then replace it though, I think. I've updated this function to do that.
source/blender/makesdna/DNA_object_types.h
61	Yeah, probably doesn't matter enough to move it.

I couldn't find this important change in release notes, so I added it to the Animation & Rigging section.
