Hi there,
Hope you’ve all had a good Christmas and are about to have a happy new
year :). I’ve been using 2.8 daily builds for a few days now that Christmas has
allowed me some time off regular duties. I am working on making our addon
compatible with it, but I notice that bpy.handlers.scene_upate_post/pre have
been removed. Per the discussions that have occurred on the task T47811
(https://developer.blender.org/T47811 <https://developer.blender.org/T47811>)
regarding this I was under the impression that we were not going to remove
them, at least not yet. Better yet there were comments about repairing them so
that they make calls to their subscribers only when something in the scene has
changed. There was no mention on this task about them actually going to be
removed so I was surprised when I noticed that they are no longer there.
As mentioned in my latest comment on the thread, we need to use this,
preferable in its repaired form rather than how it used to be. Our addon needs
notification of changes to blender’s data. I don’t see how we can accomplish
this without having some callback we can subscribe to that notifies us of
changes to the data of the scene. I’ve made a case in the task linked to above
for why we need this so I won’t go into it further here. I’d just like to hear
from the devs why this decision was made, and what the proposed alternative is?
I’ve had a good look around the new python api in the current 2.8 and can’t see
anywhere I can subscribe to get notifications about changes to the scene as I
was able to do in pretty much any prior release I’ve used.
Any guidance on what the future holds for the scene_update_post and pre
handlers would be greatly appreciated, restoring them to a fully functional
state would be even better :D
All the best
James
