This is an editor-level abstraction for the `BLO_library_temp_xxx()`
API for temporary loading of data-blocks from another Blend file. It
abstracts away the asset specific code, like asset file-path handling
and local asset data-block handling.
Main use-case for this is applying assets as presets that are based on
data-blocks, like poses. Such preset assets are an important part of the
asset system design, so such an abstraction will likely find more usage
in the future.
Adds the following to `bpy.types.FileSelectEntry`:
* `id_type`: The data-block type the file represenets, if any.
* `local_id`: The local data-block it represents, if any (assets only).
And the following to `bpy.types.AssetHandle`:
* `local_id`: The local data-block the asset represents, if any.
This kind of information and the references are important for asset related
operators and UIs. They will be used by upcoming Pose Library features.
Implements a basic, WIP version of the asset list. This is needed to
give the asset view UI template asset reading and displaying
functionality.
See:
* Asset System: Data Storage, Reading & UI Access - https://developer.blender.org/T88184
Especially the asset list internals should change. It uses the
File/Asset Browser's `FileList` API, which isn't really meant for access
from outside the File Browser. But as explained in T88184, it does a lot
of the stuff we currently need, so we (Sybren Stüvel and I) decided to
go this route for now. Work on a file-list rewrite which integrates well
with the asset system started in the `asset-system-filelist` branch.
Further includes:
* Operator to reload the asset list.
* New `bpy.types.AssetHandle.get_full_library_path()` function, which
gets the full path of the asset via the asset-list.
* Changes to preview loading to prevent the preview loading job to run
eternally for asset views. File Browsers have this issue too, but
should be fixed separately.
With temporary I mean that this is not intended to be part of the
eventual asset system design. For that we are planning to have an
`AssetRepresentation` instead, see T87235. Once the `AssetList` is
implemented (see T88184), that would be the owner of the asset
representations.
However for the upcoming asset system, asset browser, asset view and
pose library commits we need some kind of asset handle to pass around.
That is what this commit introduces.
Idea is a handle to wrap the `FileDirEntry` representing the asset, and
an API to access its data (currently very small, will be extended in
further commits). So the fact that an asset is currently a file
internally is abstracted away. However: We have to expose it as file in
the Python API, because we can't return the asset-handle directly there,
for reasons explained in the code. So the active asset file is exposed
as `bpy.context.asset_file_handle`.
For the Asset Browser, this returns the active asset library of the
Asset Browser, otherwise it returns the one active in the workspace.
This gives simple access to the active asset library from UI code and
Python scripts. For example the upcoming Pose Library add-on uses this,
as well as the upcoming asset view template.
This per-workspace active asset library will be used by the asset views
later. Note that Asset Browsers have their own active asset library,
overriding the one from the workspace.
As part of this the `FileSelectAssetLibraryUID` type gets replaced by
`AssetLibraryReference` which is on the asset level now, not the
File/Asset Browser level. But some more work is needed to complete that,
which is better done in a separate commit.
This also moves the asset library from/to enum-value logic from RNA to
the editor asset level, which will later be used by the asset view.

The `__enter__` function of the `bpy.data.libraries.load` context manager

used in the `__exit__` function, causing a crash. This is now fixed.

Mainly naming (also droping the `layer_collection` in favor of just

This logic is from the curve sundivide node, used to add points with
proper handles in between two existing points. However, the same logic
is used for trimming of Bezier splines, and possibly interactive point
insertion in the future, so it's helpful as a general utility.
The logic is converted to depend on a bezier spline instead of being
static. A temporary segment spline can be used for the latter use case.
This adds id_properties_clear() and id_properties_ensure() functions
to RNA structs. This is meant as an initial change based on discussion
in review of D9697. However, they may be useful in other situations.
The change requires refactoring the internal idproperties callback to
return a pointer to the IDProperty pointer, which actually turns out
to be quite a nice cleanup.
An id_properties attribute could be added in the future potentially.

The BKE_gpencil_stroke_add_points API function worked well for
creating the primitives in the add object menu, but it expected a
specific data format that doesn't make sense in a dynamic context.
As evidence of that we can see the way source data was duplicated
in the line art file just to use this API function.
This commit solves that problem in two ways:
- Clean up the line art function (this should make it faster too).
- Move/rename the function so its intended use is more clear.

Non-pointer-like properties that are not editable should never generate
override operations.
While harmless (those would never be applied back anyway), better not
clutter override operations list, and also enjoy the symbolic
performances improvement here.
NOTE: Pointer-like properties (pointers and collections) remain
processed as usual here since they usually imply recursivity. We could
make an exception to the exception for ID pointers, but for now I don't
think this is worth it.
Issue would happen when the original, linked data already had 'Disk Cache'
setting enabled. Override would then see no difference with linked data,
and not create any rule for it (as expected).
Root of the issue was that in Cloth modifier copy code, those disk cache
settings were not copied at all, so every time local overrides were
re-generated by copying linked data, those flags would be reset to their
default values.
NOTE: this might exist in other PointCache usages as well, but this code is
in such a bad state that I'd rather do minimal strictly needed changes
there, on a case-by-case basis. Proper recode of that whole system is
wayyyyy out of scope here.
When image strip is added from python using `image_strip_add` operator

nodes or sockets" error
rBfe22635bf664 introduced a utility to check for this (but it was always
returning true).
This wasnt a problem in master (since it is unused there), but in the
2.93 branch, this utility is actually used and the error results in all
geometry nodetrees to appear with the "Node group has unidentified nodes
or sockets" message (and being unusable).
Now return false in has_undefined_nodes_or_sockets if all nodes and
sockets have been successfully checked.
This commit then needs to end up in the 2.93 branch.

Socket inspection helps with debugging a geometry node group.
Now, when hovering over a socket, a tooltip will appear that provides
information about the data in the socket. Note, socket inspection only
works for sockets that have been computed already. Nodes that are not
connected to an output are not computed.
Future improvements can include ui changes to make the tooltip look
more like in the original design (T85251). Furthermore, additional
information could be shown if necessary.

Link sockets are always connected to inserted translate or scale

This causes crashes on full frame mode when operations read inputs
with non expected datatypes.
Because data type conversions need to be executed before, convert
resolutions must ensure same datatypes are linked.
This commit moves the storage of `bDeformGroup` and the active index
to `Mesh`, `Lattice`, and `bGPdata` instead of `Object`. Utility
functions are added to allow easy access to the vertex groups given
an object or an ID.
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 an object.
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 in this commit are invasive enough as it is.
Note that opening a file saved in 3.0 in an earlier version means
the vertex groups will not be available.
