Stored `ComponentIDKey` and `OperationIDKey` would still use string
references (char pointers) to data in related IDs, instead of using the
already locally stored std::string name of their matching `ComponentNode`
or `OperationNode` for that.
During undo, to reduce updates and speedup undo steps, a lot of IDs get
'replaced in place', i.e. new data read from the undo memfile is moved
into the existing 'old' ID memory address. And the depsgraph is also
re-used from the old BMain.
Calling `DEG_id_tag_update` and similar on the ID could then cause
depsgraph code to access freed memory from the 'old' data.
Joint effort with @sergey and the rest of the depsgraph team, thanks!
Issue caused by inconsistency in GPUFramebuffer viewport state
between Metal and OpenGL. The MTLFramebuffer code has been
modified such that framebuffer viewport/scissor state is retained
and only updated if attachments are modified during bind.
This is consistent with OpenGL. Previously, other updates to the
framebuffer in Metal would reset the viewport region, especially
if attachments were temporarily removed. This caused the color
picker selection to be misaligned.

Autosave files are created from memfile undo, which
doesn't save legacy mesh data. This leads to a crash
on file load.
In addition the mesh code can now add CustomData
layers when saving files, which did not work if
the original domain had no layers. In that case
CustomData.layers is NULL and DNA has nothing to
key off of when loading the file later.

CustomData_get_active_layer_index() was used by accident. But that
returns the CustomData layer index (in all layers) as opposed to
CustomData_get_active_layer(), which returns the active UV layer.

Check the specific case of `OP_IS_REPEAT_LAST` and recalculate
the orientation.
To that, pass the `OP_IS_REPEAT` and `OP_IS_REPEAT_LAST` flags as
inheritance to macro operators.
Force field absorption allows dampening of force fields by colliders, but it does not currently work when the scene only contains a rigid body simulation. It requires a particle simulation, cloth, dynamic paint, fluid sim, or softbodies for the feature to work correctly.
The reasons is that the effector function computing force field strength uses depsgraph relations to determine which colliders "absorb" the force field. If there are no dependencies between colliders and effectors registered in the depsgraph, the visibility function `eff_calc_visibility` does not add any absorption.
There is a function build_collision_relations which adds a dependency between the absorption object (the one with a collision modifier) and the forcefield object. It's currently only called by
1. Particle systems (DepsgraphRelationBuilder::add_particle_collision_relations)
2. Cloth, DynPaint, Fluid, and Softbody (DEG_add_collision_relations and indirectly through DEG_add_forcefield_relations).
The `DepsgraphRelationsBuilder` now adds the effector relations also when building rigid body relations.

Since e3801a2bd4, we would always respect
hiding for vertex paint and weight paint (drawing code and stroke based
painting), leaving an inconsistency between the different paintmodes.
To rectify this, now also always respect edit mode hiding for projection
painting as well.
Some feedback was gathered in #sculpt-paint-texture-module to ensure
this is desired behavior.
Note: this does not change the (experimental) texture painting in
sculptmode [this already respects hiding via PBVH, albeit in a manner
that bleeds into hidden faces if the brush center is over visible faces]

After investigating the crash logs it looked like the macro
unrolling wasn't working on Windows systems with these GPUs.
Macro unrolling was changed in order to cross compile to Metal and
in the future to Vulkan. The macro unrolling in OpenGL can be removed
by using a different naming scema.
This PR removes the macro unrolling by changing the generated GLSL
code:
**Before**
```
layout(std140) uniform _probe_block
{
ProbeBlock probe_block;
};
```
**After**
```
layout(std140) uniform probe_block
{
ProbeBlock _probe_block;
};
```
Some tweaks had to be done to the Eevee-shaders to make sure that
the macro unrolling is done correctly and could be compiled using
legacy opengl drivers.

Python has several different string types [0], each using a prefix to
indicate the type. Presently Blender's Text Editor / syntax highlighting
does not include the prefix as part of the string, which makes the
prefix appear as a syntax error. This patch looks for these prefixes,
and includes them with the string highlighting.
Note: prefixes can appear in either case (ex: f and F mean the same
thing), and some prefixes can be combined (ex: fr is a raw f-string).

The legacy conversion from MLoopUV to generic attributes used the
active and default layer names to copy the active/render status to the
new layers. But sometimes the names can change, and they weren't
updated in that case. Instead, store the active status with an index
into the names array (use an array instead of Vector for clarity).
fa0f295b53 exposed that there was a region missing because of some
faulty versioning.
The `fluid_motion_blur.blend` Cycles test file was crashing. Seems like
this is a pre 2.5 file that was resaved in newer versions, but the
preview region for the Sequencer was missing. Before mentioned commit,
the region would be broken when activating the preview view mode in the
Sequencer, now it would crash even on startup.
Ensure the region exists, as expected.
Introduces *ARegionType.poll()* as a way to dynamically add/remove a region. The region is still there internally, but is not accessible to the user.
Previously editors would to this manually, by either removing/adding regions altogether, or hiding them, unsetting their alignment (so no AZones are added I assume) and removing their event handlers. Polling makes this much simpler.
We plan to use this in #102879.
This patch refactors multiple editors to use region polling:
- File Browser
- Sequencer
- Clip Editor
- Preferences
Notes:
- Previously, editors would lazy-create some of the regions. Versioning is added here to ensure they are always there. Could be a separate patch.
- Some editors reuse a region in different display modes, and so additional work needs to be done to reinit regions they become available or the mode changes. Typically `V2D_IS_INIT` is unset for that, which isn't great. Could be improved, but not a new issue.
Behavior change:
- When the Preferences are opened as a regular editor, the "execution" region in the preferences that displays the *Save Preferences* button would still be there, but empty with a scrollbar.
This patch makes it disappear entirely.
## Implementation
- Introduces `ARegionType.poll()`
- Before a window is drawn, all contained regions have their poll checked, and the result is stored in a flag (`RGN_FLAG_POLL_FAILED` - runtime-only flag).
- If the result of the poll changes, the area is re-initialized and event handlers are added/removed.
- UI code checks the flag as needed.

Any errors from calling `bpy.ops.render.render(write_still=True)` would
be suppressed, making it impossible to know what went wrong.
Now the operator now reports errors when run via `exec` which mainly
occurs when the operator is called from scripts.
Interactively rendering via `invoke` is left as-is since users can see
the error in the UI and showing a popup error is disruptive.
The assets are required to build proper Blender release, so they can not be
skipped from packing.
The packing ignores the `working` directory as it seems to be big and sounds
that it is not needed for the release.
The assets are bundled under the `release/datafiles/assets` folder in the
blender sources. This is where they will reside after switch to the Git LFS.

The "reverse map" of corners to faces and points to curves is the same
for meshes and curves now. Move it to the offset indices header to
reflect this.
This unification can go further in the future, but I'd rather wait
until the design is clearer for now.
Pull Request: https://projects.blender.org/blender/blender/pulls/106570
Implements #95967.
Currently the `MPoly` struct is 12 bytes, and stores the index of a
face's first corner and the number of corners/verts/edges. Polygons
and corners are always created in order by Blender, meaning each
face's corners will be after the previous face's corners. We can take
advantage of this fact and eliminate the redundancy in mesh face
storage by only storing a single integer corner offset for each face.
The size of the face is then encoded by the offset of the next face.
The size of a single integer is 4 bytes, so this reduces memory
usage by 3 times.
The same method is used for `CurvesGeometry`, so Blender already has
an abstraction to simplify using these offsets called `OffsetIndices`.
This class is used to easily retrieve a range of corner indices for
each face. This also gives the opportunity for sharing some logic with
curves.
Another benefit of the change is that the offsets and sizes stored in
`MPoly` can no longer disagree with each other. Storing faces in the
order of their corners can simplify some code too.
Face/polygon variables now use the `IndexRange` type, which comes with
quite a few utilities that can simplify code.
Some:
- The offset integer array has to be one longer than the face count to
avoid a branch for every face, which means the data is no longer part
of the mesh's `CustomData`.
- We lose the ability to "reference" an original mesh's offset array
until more reusable CoW from #104478 is committed. That will be added
in a separate commit.
- Since they aren't part of `CustomData`, poly offsets often have to be
copied manually.
- To simplify using `OffsetIndices` in many places, some functions and
structs in headers were moved to only compile in C++.
- All meshes created by Blender use the same order for faces and face
corners, but just in case, meshes with mismatched order are fixed by
versioning code.
- `MeshPolygon.totloop` is no longer editable in RNA. This API break is
necessary here unfortunately. It should be worth it in 3.6, since
that's the best way to allow loading meshes from 4.0, which is
important for an LTS version.

`PLATFORM_BUNDLED_LIBRARIES` was installing right next to the blender
executable rather than the `blender.shared` folder,
`PLATFORM_BUNDLED_LIBRARIES` wasn't used very much on windows, just
by the ONEAPI code which likely wasn't aware this plumbing was
still missing.
This diff adds support for using `PLATFORM_BUNDLED_LIBRARIES` on
windows in both debug and release configurations.
You can differentiate between a .dll being installed for debug/release
or all configurations, by prefixing the library with either `DEBUG`,
`RELEASE` or `All`, if no prefix is given `ALL` is assumed.
