The goal is to solve confusion of the "All rights reserved" for licensing
code under an open-source license.
The phrase "All rights reserved" comes from a historical convention that
required this phrase for the copyright protection to apply. This convention
is no longer relevant.
However, even though the phrase has no meaning in establishing the copyright
it has not lost meaning in terms of licensing.
This change makes it so code under the Blender Foundation copyright does
not use "all rights reserved". This is also how the GPL license itself
states how to apply it to the source code:
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This program is free software ...
This change does not change copyright notice in cases when the copyright
is dual (BF and an author), or just an author of the code. It also does
mot change copyright which is inherited from NaN Holding BV as it needs
some further investigation about what is the proper way to handle it.
The Node Add menu can have special submenus containing node assets.
These submenus are generated by parsing the asset blend files from
release/datafiles/assets, and the interface drawing is specific to
these menus.
This commit enables the translation of these dynamic menus, including
their names and the description of the operators.
The crash is fixed by reverting 87fd798ae3 and
some follow up commits. While it would generally be nice to move to a more
SoA format for these things, we are not there yet and this is causing more
trouble than it's worth currently. The main difficulty is that the socket
indices are changed by many different operations which invalidates the array
too often and led to many follow up bugs.
Pull Request: https://projects.blender.org/blender/blender/pulls/105877
Various UI code would store the `AssetHandle` in a way that turns out to
be unsafe. The file-data is part of the file browser caching system that
releases file-data when a certain maximum of items is in the cache. So
even while just iterating over the assets, earlier iterated asset
handles may become invalid. Now asset handles are really treated as
volatile, short lived objects.
For the asset-view, the fix was more involved. There we need an RNA
collection of asset-handles, because the UI list code requires that. So
we create a dummy collection and get the asset handles as needed by
index. This again meant that I had to keep the index of the collection
and the asset-list in sync, so all filtering had to be moved to the UI
list.
I tried duplicating the file-data out of the cache instead, but that
caused problems with managing the memory/ownership of the preview
images.
`AssetHandle` should be removed and replaced by `AssetRepresentation`,
but this would be an even more disruptive change (breaking API
compatibility too).
Fixes#104305, #105535.
Pull Request: #105773
Nodes are sorted based on the selection. In some cases (even depending
on processor speed, nodes can be selected and reordered, and another
operation can run before the next redraw). That gives a window where
operators mapped to the same input as selection can run with invalid
socket locations (which aren't updated after the nodes are reordered,
since they are stored in a separate array).
To fix this, move the socket locations from the node editor runtime
data to the node tree, tag them as invalid when the nodes are
reordered, and check for that status in a few more places.
A better longer term solution is not reordering nodes based on
UI status and instead storing the UI drawing order separately.
Pull Request #104420
Socket locations are set while drawing the node tree in the editor.
They can always be recalculated this way based on the node position and
other factors. Storing them in the socket is misleading. Plus, ideally
sockets would be quite small to store, this helps us move in that
direction.
Now the socket locations are stored as runtime data of the node editor,
making use of the new node topology cache's `index_in_tree` function
to make a SoA layout possible.

With the asset identifier introduced in the previous commit, we can now
locate an asset just from its `AssetRepresentation`, without requiring
information from the asset library and the file browser storage. With
this we can remove some hacks and function parameters. A RNA/BPY
function is also affected, but I didn't remove the paramter to keep
compatibility. It's simply ignored and not required anymore, noted this
in the parameter description (noted for T102877).
* This patch just moves runtime data to the runtime struct to cleanup
the dna struct. Arguably, some of this data should not even be there
because it's very use case specific. This can be cleaned up separately.
* `miniwidth` was removed completely, because it was not used anywhere.
The corresponding rna property `width_hidden` is kept to avoid
script breakage, but does not do anything (e.g. node wrangler sets it).
* Since rna is in C, some helper functions where added to access the
C++ runtime data from rna.
* This size of `bNode` decreases from 432 to 368 bytes.
This allows for optimizations because one does not have to iterate
over all nodes anymore to find all nodes within a frame.

This patch builds on the work from bdb5754147 to add node group
assets directly in the node editor add menu. Assets are added after
separators to distinguish them, but otherwise they look like any other
node. The catalog trees from all configured libraries are used to build
the menu hierarchy. Only catalogs with matching asset types are used
though.
There are a few limitations of this initial version. For now this only
supports geometry nodes. Support for other built-in node systems just
requires some refactoring of the corresponding add menu though. Lazy
loading will be added in a followup commit. For now there is a label
the first time the menu is opened.
Like the search menu integration, re-saving asset library files in 3.4
is required, if it hasn't been done already.
Implementation wise, there is a some ugly code here. A lot of that is
because the asset system isn't complete. The RNA API doesn't work well
yet, and the system isn't built to interact with multiple libraries at
once. It's also ugly because of the way we combine automatic menu
generation with builtin menus. As noted in a code comment, these two
systems could be merged completely so that the menus for builtin nodes
are also generated in the same way.

Fix reroute nodes added via the cut link gesture being parented to the
wrong frame node.
The frame's bounds that are used for the intersection test with the
newly added reroute are in view space, but the reroute's location was
given in the node tree's coordinate space, when the add reroute
operator was recently refactored (56193eccf6).

Currently node group assets are supported, but using them by dragging
from the asset browser is cumbersome. This patch adds all node group
assets from user asset libraries and the current file libraries to the
add node search menu and the link drag search menu.
Node groups added through the search will have their "options" hidden,
meaning the data-block selector is displayed. This helps keep the UI
clean, and the selector shouldn't be necessary anyway.
To make that possible, metadata like the node tree type and its inputs
and outputs has to be saved in the file. This requires re-saving the
files that contain the assets with the patch applied.
The node add search operator is moved from Python to C++ to ease
development and allow more flexibility. It supports a tooltip that
gives the description of assets.
Currently the node groups are added with the asset system's existing
"Append & Reuse" behavior. It's likely that linking should be possible
in the future too, but for now the idea is to use the more foolproof
option that doesn't create dependencies between files.
Because loading assets can potentially take a long time, the search
menu refreshes its items as new assets are loaded. However, changing
the search field is necessary to see the update.

Use C++ Map that supports the duplication natively. Use vectors instead
of linked lists, and adjust naming. Also remove combination of reroutes
for input sockets, which doesn't make sense since a reroute isn't
allowed to combine multiple input links into one output.
Now dragged handles are handled separately, and the function returns a
statically sized array by value. The functions are also renamed to be
more consistent with curve naming elsewhere in Blender.
If reroute node lies in side the frame node boundaries then set
frame node as the parent of reroute.

Oversight in b0da080c2c. The `session_uuid` operator property wouldn't
be checked by the invoke callback, and if neither the `filepath` nor the
`name` property were set, the File Browser would open.
Dropping would pass the name of the ID to drop to the properties of the
drop operator. This would then lookup the ID by name. With linking
and/or library overrides, multiple IDs of the same name and type may
exist, which is why the session UUID should be used instead. All
operators used for dropping support this now and the drop code passes
the session UUID instead of the name.
Also see 917c096be6 and 8f79fa9c67.
Some drop operators were already using the session UUIDs. This converts
the remaining ones. The "name" property is kept working as before, since
some scripts use this.
Side-effect: The "Name" property won't show up in the Adjust Last
Operation anymore, which was the case for some of these operators, and
its value won't be remembered over multiple executions of the operator.
Both were not at all useful from what I can tell, and I doubt this was
done intentionally.
There are now some generalized helpers for passing IDs from drag & drop
to operators via operator properties, mostly introduced in 917c096be6
and 8f79fa9c67. These can be used in a bunch of places to reduce
duplicated code and explicitly share a common solution.

This commit removes the implementations of legacy nodes,
their type definitions, and related code that becomes unused.
Now that we have two releases that included the legacy nodes,
there is not much reason to include them still. Removing the
code means refactoring will be easier, and old code doesn't
have to be tested and maintained.
After this commit, the legacy nodes will be undefined in the UI,
so 3.0 or 3.1 should be used to convert files to the fields system.
The net change is 12184 lines removed!
The tooltip for legacy nodes mentioned that we would remove
them before 4.0, which was purposefully a bit vague to allow
us this flexibility. In a poll in a devtalk post showed that the
majority of people were okay with removing the nodes.

This commit moves code in all node editor files to the
`blender::ed::space_node` namespace, except for C API
functions defined in `ED_node.h`, which can only be moved
once all areas calling them are moved to C++.
The change is fairly straightforward, I just moved a couple
of "ED_" code blocks around to make the namespace more
contiguous, and there's the method for adding a pointer to
a struct in a C++ namespace in DNA.

We can't include `BLI_utildefines.h` in `RNA_types.h` since Cycles includes
that, but duplicates some of the util defines. So you'd have duplicated
definitions.
Goals of this refactor:
* More unified approach to updating everything that needs to be updated
after a change in a node tree.
* The updates should happen in the correct order and quadratic or worse
algorithms should be avoided.
* Improve detection of changes to the output to avoid tagging the depsgraph
when it's not necessary.
* Move towards a more declarative style of defining nodes by having a
more centralized update procedure.
The refactor consists of two main parts:
* Node tree tagging and update refactor.
* Generally, when changes are done to a node tree, it is tagged dirty
until a global update function is called that updates everything in
the correct order.
* The tagging is more fine-grained compared to before, to allow for more
precise depsgraph update tagging.
* Depsgraph changes.
* The shading specific depsgraph node for node trees as been removed.
* Instead, there is a new `NTREE_OUTPUT` depsgrap node, which is only
tagged when the output of the node tree changed (e.g. the Group Output
or Material Output node).
* The copy-on-write relation from node trees to the data block they are
embedded in is now non-flushing. This avoids e.g. triggering a material
update after the shader node tree changed in unrelated ways. Instead
the material has a flushing relation to the new `NTREE_OUTPUT` node now.
* The depsgraph no longer reports data block changes through to cycles
through `Depsgraph.updates` when only the node tree changed in ways
that do not affect the output.
Avoiding unnecessary updates seems to work well for geometry nodes and cycles.
The situation is a bit worse when there are drivers on the node tree, but that
could potentially be improved separately in the future.
Avoiding updates in eevee and the compositor is more tricky, but also less urgent.
* Eevee updates are triggered by calling `DRW_notify_view_update` in
`ED_render_view3d_update` indirectly from `DEG_editors_update`.
* Compositor updates are triggered by `ED_node_composite_job` in `node_area_refresh`.
This is triggered by calling `ED_area_tag_refresh` in `node_area_listener`.
Removing updates always has the risk of breaking some dependency that no
one was aware of. It's not unlikely that this will happen here as well. Adding
back missing updates should be quite a bit easier than getting rid of
unnecessary updates though.
