In case a part of an override hierarchy would still be linked data, and
there would be other liboverride hierarchies sharing usage of that same
linked data, trying to create a partial override of that linked data
into a hierarchy would create very unreliable results.
This commit now only process each ID at most once, to ensure that the
liboverride will only be put in one liboverride hierarchy.
This is only a partial fix, results now should at least always be
valid. However, due to inheritently broken Outliner code when it comes
to same data in more than one path of the tree, the place where
(hierarchy in which) the new liboverride will be created is currently
'random' and unpredictable from user perspective.
This commit contains some code to try to alliviate that (by enforcing
processing of the active elements first), but unfortunately this does
not work either.
- Do not remap local liboverrides from other hierarchies when a
liboverride hierarchy root is provided (such that in case a linked
data is overridden as part of one hierarchy, the new liboverride does
not get assigned to other liboverride hierarchies of the same reference
data).
- Do not attempt to instanstiate newly overridden collections or objects
when they are part of a hierarchy and not the root of that hierarchy
(as they can be sondiered as already handled through that hierarchy
processing). Avoids attempts to instantiate them when doing partial
liboverride into an already existing hierarchy.
Adds the "Corners of Edge" topology node to geometry nodes.
Combining this node with the "Face of Corner" node allows getting
informations about the faces connected to an edge. The behavior is
slightly non-obvious-- the node only gives the corner neighbors
that come *before* the current edge in directly neighboring faces.
This allows the operation to be easily reversed and reduces
redundancy between nodes.

2ffd08e952 introduced new system to control attribute life time.
Some specific function for that system is missed in `Shortest Edge Paths`.
This pull request add this functions:
1. `reference_pass_all` for socket declarations.
2. `for_each_field_input_recursive` for field input nodes.

When entering sculpt mode on an object without any color attributes and
starting to paint, the newly created color attribute was set active, but
not default (camera icon).
Now set it default as well.

Follow up to [0], some material data wasn't accounted for.
- The embedded node-tree's owner_id wasn't set.
- Animation data (both the material & it's embedded node-tree).
- Updating depsgraph relations is needed when animation data is freed
as part of paste too.
Also report when paste fails.

Commented [0] (2.5x refactor that disabled many free functions),
for some reason this call was never re-enabled.
Add back the free call along with other clipboard buffers.

Cherry picked [1] from main as other fixes material clipboard
are difficult to validate when memory is leaking.

Use a macro to make the ID-free switch more compact & use ID indices
for better readability. Also typedef the enum so missing types in the
switch will report compiler warnings.
When a file passed in from the command line failed to load,
blender would exit & save the quit.blend.
Resolve by adding a `do_user_exit_actions` to WM_exit_ex which is
false in backgrounds mode or when an error has occurred.

The "no custom" normal used to be stored inside the custom normal space
struct, now it's stored separately. Before the normal was modified, but
not the one in the normal space struct. Fixed by storing the original
before modification in a temporary variable.
This function replaced the evaluated mesh with a new one with the given
custom data type mask. That doesn't work in general anymore for a few
reasons: the increased dependence on named attributes (a opposed to
custom data types), and the "all or nothing" approach to reevaluating
the depsgraph. Other objects might depend on the object's evaluated
geometry, so it shouldn't just be replaced. Pushed a bit further, this could
give nice simplifications to mesh modifier evaluation.
There are two breaking changes, `bmesh_from_object` and BVH tree
`FromObject` require the source object to have a proper evaluated
mesh now.
If this causes a regression, it's likely that the object is missing
an update tag when a mode is entered that requires extra evaluated data.

2a56403cb0 changed the way bevel weights are stored in 4.0.
Add versioning for reading the new files that replaces the new generic
attributes with the old non-generic custom data layers. The code is
paranoid with lots fo checks I expect will typically not be necessary.
For emitter particle systems, these were never rendered anyways, Path is
kept for hair systems of course.
As a consequence, the new default for particle systems is:
- render as None (users have to explicitly set this to object/
collection)
- display as point
When changing to Hair type, this automatically gets set back to
- render as Path
- display as Render
Changing back to emitter, will use points as display again (and render
as None -- same here, users have to explicitly set this to object/
collection)
Not sure if this is still for 3.6, patch is for 4.0 for now.
"Fixes" #80197

The code which was preventing this originated to an early days of the
light linking project where bits accumulation was done as part of the
graph evaluation. Since then it was changed to be pre-calculated at
the graph build time.
The updates of the receivers is ensured via the HIERARCHY nodes and
relations between them.
Also made it explicit that the emitter is updated with the tag of
the collection: before it was relying on implicit Copy-on-Write
component tag.

Small correction to word selection in Console. Start and end of
selection were in incorrect order so it displayed correctly but
did not copy to clipboard as expected.
Pull Request: https://projects.blender.org/blender/blender/pulls/108434
This is a continuation of a fix from the last week in #108311.
The issue was not fully fixed due to a mistake in the regression
test file.
There are two major things which left to be fixed since the
previous patch:
1. Root nodes can not be shared, even if the local and distant
lights belong to the same light set. If the root node is shared
then the flattening will use the same node index for specialized
trees, which is not a desired behavior.
2. The node type needs to be preserved when a new node is
created for a subset of emitters. This is because tree sampling
in kernel will handle distant and local lights differently for
nodes where there are multiple emitters.

A missing `CONSTRAINT_OFF` check in `transform_convert.c` causes the
inverse matrix of that constraint to be added on top of the translation,
causing weird translation response in the viewport. Now fixed.
