System Information
Operating system: Windows-10-10.0.18362-SP0 64 Bits
Graphics card: GeForce GTX 1070/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 457.30

Blender Version
Broken: version: 2.92.0 Alpha, branch: master, commit date: 2020-11-17 22:10, hash: 3e325c35f8
Worked: (newest version of Blender that worked as expected)

Short description of error
When you rename bones of armatures with some meshes by python scripts and then do Undo (Ctrl +z), then only bone names are reverted and the mesh vertex groups are never reverted.
It seems to happen immediately after from Object mode to Edit mode for armatures.

Exact steps for others to reproduce the error

Open "bpy_rename_bone_and_undo_bug_report.blend".
Go to Armature Edit mode.
Run script "rename.py". It will rename selected bones and the mesh vertex groups.
Do undo (Ctrl +z)
Then you will see only bone names are reverted and the mesh vertex groups aren't reverted.

bpy_rename_bone_and_undo_bug_report.blend

It will lost bone deformations.
I thinks it will cause some human errors.

Thanks!

Thanks for the report I can confirm the problem.
The script makes it easier to reproduce.

In fact, the undo only partially reverts the operator's result.

It must be a conflict in the context, but in fact it shouldn't happen.

Not sure if this is for the #animation_rigging team or #data_assets_i_o

This is usual same issue, armature editmode uses non-memfile undo steps, which ignores changes made to other IDs... Not much to do here, this is known limitation.

Bastien Montagne changed title from ~~Undo won't work correctly when you rename bones of armatures with some meshes by python scripts.~~ to Undo in Armature EditMode ignores changes to other IDs
