Simplified Report

Open the attached file, replace the path with a path to any USD file.
Run the script.
Blender hits the following assert.
Most likely related to #101272.

BLI_assert failed: source/blender/blenkernel/intern/layer.c:509, BKE_view_layer_copy_data(), at '(view_layer_src->flag & VIEW_LAYER_OUT_OF_SYNC) == 0'
  View Layer Object Base out of sync, invoke BKE_view_layer_synced_ensure.

viewlayer_bug.blend

The script is as follows:

import bpy

usd_collection = bpy.data.collections.new("TEST_COLLECTION")
bpy.context.scene.collection.children.link(usd_collection)
layer_collection = bpy.context.view_layer.layer_collection.children['TEST_COLLECTION']
bpy.context.view_layer.active_layer_collection = layer_collection

bpy.ops.wm.usd_import(filepath = "/path/to/any/file.usd", relative_path = False)

Short description of error
If you create a collection via python, in the code just after that, if you try to make it active, python will throw an error.
I think it must be a recently introduced bug, because you can actually see the collection in the outliner, and if you try the same code ( the make active collection part ) in a separate script execution, the code works.
To help, i suggest that maybe it can be related to recently introduced funcionality of lazy loading here? https://developer.blender.org/rB68589a31ebf
I suspect that because i´m trying to access to the viewlayer, and in fact, after executing the code, then you can use the exact same code just commenting the creation part ( collection creation code on the first line just worked ), then it works.

The code:

usd_collection = bpy.data.collections.new("TEST_COLLECTION")
bpy.context.scene.collection.children.link(usd_collection)
layer_collection = bpy.context.view_layer.layer_collection.children['TEST_COLLECTION']
bpy.context.view_layer.active_layer_collection = layer_collection

Exact steps for others to reproduce the error
Just exectute the script in the file attached, it will throw the error. As mentioned above, after the first fail, if you comment the 2 first lines of code and execute it again ( because the collection its already created ) now it works.
It seems to be that the viewlayer isnt accessible even if its already created, like it needs blender to refresh the UI or something?{F13580347}

I guess that is the same as #101272. Which was fixed today in 4a60c4746d. Can you try tomorrows daily build that includes the fix and see if indeed fixes the issue?

I tried with the last daily build, blender-3.4.0-alpha+master.788f3d72cf89-windows.amd64-release.

Now it doesn´t throw the error, but still failing to make the collection active, to making the objects inside this collection selected... anything related to this is now ignored.

Same behaviour as before though, if you execute the script again after all is created, it works, but not on the first try, so it must remain some other sections of code, that aren´t aware of the updates, not only the view layers.

This part after the collection creation is ignored on the first script execution:

layer_collection = bpy.context.view_layer.layer_collection.children['TEST_COLLECTION']
bpy.context.view_layer.active_layer_collection = layer_collection

collection = bpy.data.collections["TEST_COLLECTION"]
for obj in collection.all_objects:
    obj.select_set(True)

No collection active, no objects inside the collection selected.

if you execute it again ( when the collection it´s already existing and you can see it from the outliner ), then this part works normally
there´s still some parts that need updating imho.

I am confused because the newly added collection doesn't have any objects yet, so how are you trying to select its object?
As for the collection being active, it seems to be working fine for me. How do you determine that it isn't?
Can you clarify those points?

I can´t share the entire script because is an in-house tool and property of the company i´m working on.
This chunk function is to create that temp collection to import a USD file on it, make it active, then import the USD and finally select every object inside this collection.
The important thing here is that same code chunk worked before view layer changes, so the update fix must be incomplete somewhere.

usd_collection = bpy.data.collections.new("TEST_COLLECTION")
bpy.context.scene.collection.children.link(usd_collection)
layer_collection = bpy.context.view_layer.layer_collection.children['TEST_COLLECTION']
bpy.context.view_layer.active_layer_collection = layer_collection

bpy.ops.wm.usd_import(filepath="path"), 
    relative_path=True, 
    set_frame_range=False, 
    import_cameras=False, 
    import_curves=False, 
    import_lights=False, 
    import_volumes=False, 
    import_subdiv=True, 
    read_mesh_colors=True, 
    import_guide=True, 
    mtl_name_collision_mode='REFERENCE_EXISTING')

collection = bpy.data.collections["TEST_COLLECTION"]
for obj in collection.all_objects:
     obj.select_set(True)

On the last build, this same code does not select anything inside it and didn´t make the collection active.

Assert is introduced by 68589a31eb.
During loading a scene can be copied. The original scene should be already be in synced before calling copy, because copy only accepts a ready only source scene.

Will try to reproduce to find the exact stack trace.

Analyzed the blend file and have the following question and remark:

Somehow the scripts triggers a viewlayer.update(). From the stack trace it's unclear to me where this is coming from. I guess some listener is triggered when the usd_import ops is performed? Anyone any idea?
Looking into the viewlayer.update(), it seems that the script fails because there are 2 viewlayers in the file of which 1 is only resynced (probably the active one ), the other one not. The depsgraph makes a copy of the scene which fails because of the viewlayer out of sync.
A way to solve this could be that depsgraph syncs all viewlayers before copying. Or we could mark all dest viewlayers "dirty" when copying and remove the assert.

I would suggest the 2nd solution, but would like to hear from @mont29

I think the depsgraph should ensure all view layers from all scenes it 'handles' are in sync when it starts an update process. Reason being, depsgraph expects valid 'static' data to work on (for relations building etc.), so imho one cannot expect it to work with non-updated 'dirty' viewlayers at all? @dr.sybren , @Sergey, maybe you have better insight here?

Sergey Sharybin commented

2022-10-05 09:49:49 +02:00

I am not sure what exactly it means. If the construction of depsgraph is somehow called on an invlaid state of the view layers, then the proper solution is to hide such access behind an API. To me it does not seem to be a good design to require all areas which needs to acccess view layers to ensure re-syncing of any kind. If it is something what needs to be done during evaluation, then it should follow typical tagging process. Depsgraph evaluation should not make decision to re-sync anything if it was not tagged for.

Monique Dewanchand commented

2022-10-10 21:35:12 +02:00

Reading both viewpoints, a solution can be to perform a sync on all view layers when copying the scene.

@monique It is the same code included on the original report above, but now is directly crashing blender... so i can´t know exactly which part of the script is the culprit of the crash.
I´ll try to find some time tomorrow to test with a newer buildbot release, just to make sure that the issue isn´t related to a bad build... and if not, on monday i´ll try to debug manually my code to find out.

@monique I´ve debuged my code and for me it seems like the same problem.
Just after importing a USD file into my "TEST_COLLECTION" as before :

usd_collection = bpy.data.collections.new("TEST_COLLECTION")
bpy.context.scene.collection.children.link(usd_collection)
layer_collection = bpy.context.view_layer.layer_collection.children['TEST_COLLECTION']
bpy.context.view_layer.active_layer_collection = layer_collection

1- On the working blender version, all objects inside the "TEST_COLLECTION" collection were selected automatically right after the import for you, now this doesn´t work
2- If you try to force it, this doesn´t work either :

for obj in bpy.data.collections["TEST_COLLECTION"].all_objects:
        obj.select_set(True)

After that, my code relies on this selection, so it fails because nothing on the collection created previoulsy can be selected.
If you try to execute the exact same code in the script editor after the first execution, it works as expected, so its a refresh thing again.

We also tried this when having multiple view layers. Can you try this?

Now this part it´s working on the las build from buildbot i´m using ( Broken: version: 3.4.0 Beta, branch: master, commit date: 2022-11-14 01:01, hash: 0190b104c8 )
But unfortunately, i´ve found another one that can be related somehow with a lack of refresh on the view layer here ( https://developer.blender.org/T102550 )
Thanks!
