This is not as much a fix as a work around, but given the real
involves replacing how we build fftw, it is not eligible for 2.83
which is in BCON3 already.
The root of the issue lies with (how we build) fftw3
The first issue is: fftw does not build with MSVC, there are other
dependencies that are not compatible with MSVC and for those we
build the libraries required with mingw64, same for fftw
The second issue is: for reasons unknown we really really really
liked all deps to link statically so wherever possible we did so.
Now during the building of the fftw it linked a few symbols from
libgcc (which we do not ship) like __chkstk_ms, for which we passed
some flags to stop generating calls to it. Problem solved! There
is no way this could possibly turn around and bite us in the rear.
fast forward to today mystery crashes that look like a race condition.
What is happening is, we tell the linker that each thread will require
a 2-megabyte stack, now if every thread immediately allocated 2 megs,
that be 'rough' on the memory usage. So, what happens is (for all apps
not just blender), 2 megs are reserved but not backed by any real memory
and the first page is allocated for use by the stack, now as the stack
grows, it will eventually grow out of that first page, and end up in
an area that has not been allocated yet, to deal with that the allocated
page is followed by a guard page, someone touches the guard page it's
time to grow the stack!
Meanwhile in FFTW is it's doing substantial allocation using alloca
(up to 64 kb) on the stack, jumping over the guard page, and ending
up in reserved but not yet committed memory, causing an access violation.
Now if you think, that doesn't sound right! something should have
protected us from that! You are correct! That thing was __chkstk_ms
which we disabled.
Given we do not want a dependency on libgcc while building with MSVC
the proper solution is to build fftw as a shared library which will
statically link any bits and pieces it needs, however that change
is a little bit too big to be doing in BCON3.
So as a work around, we change the size the stack grows from 8k to
68k which gives fftw a little bit more wiggle room to keep it out
of trouble most of the time.
Note this only sidesteps the issue, this may come up again if the
conditions are just right, and a proper solution will need to be
implemented for 2.90.
When the number of triangles in a node became zero, the wireframe batch was
not freed along with the triangles batch and could still reference a freed
vertex buffer.
Ref T76858
Bug was actually in outliner code, paste operator would not generate any
undo step...
This was not correct ever, but with new undo code this has become a
critical issue, it cannot survive a situation where current main data
has been changed without a proper undo push.
This illustrates again how much of a catastrophic mess the 'tools'
callbacks of the outliner are currently, it has already caused us quiet
some pain in the past, and will keep doing so until this is fully
sanitized am afraid.
Would strongly suggest getting rid of thosw nasty mix of custom
callbacks requiring manual undo pushes, I do not see the added value of
this compared to regular menus calling regular operators. It only adds
confusion and extra code for nothing...
Re-apply changes from 54ea3562406c633dc69f59697cca3cd1cded3bcd,
with a poll function that uses the same active object as the operator,
matching other mode switching functions.
This reverts commit 54ea3562406c633dc69f59697cca3cd1cded3bcd it
introduced crashes when trying to go to edit mode when the active
object was hidden.
Fix T76837
Issue is that update functions defined in
`rna_def_fmodifier_envelope_ctrl` (namely `rna_FModifier_update`) are
actually never called.
This is because UI code for FCurve modifiers often does not use RNA
buttons but uses custom update functions (or non at all). For example,
rB9a88bd55903a did this for the generators, envelope control points did
not have this at all.
This is now changed to use RNA buttons for the envelope control points,
this could done for other non-RNA buttons as well to get rid of
'validate_fmodifier_cb()'.

This patch fixes T76277 by removing the incorrect cast from
`ptr->data` to `bNode`. The address of `ptr->owner_id` and
`ptr->data` both point to the node tree. Passing the node tree
incorrectly as a node into the `ED_node_tag_update_nodetree`
corrupts the data, because it attempts to set flags on the
node.

This error was introduced wit the change in commit https://developer.blender.org/rB6a850f3cc840
As the brushes were not created, all modes except Edit were broken.
Now, the brushes and palette are not created when load the file in versioning code, but when the mode is enabled.
Also, if the brush already exist, the parameters are not reset as it was done in the versioning code in order to keep user settings.
The same logic is used for the default palette.

Right now:
- drag-drop in the Outliner prevents dropping inside linked collections
- drag-drop in the Outliner allows dropping inside overridden
collections (should not be the case)
- `Object Properties` > `Collections` panel allows to add to overridden
collection (should not be the case)
- `Object Properties` > `Collections` panel filters out non-local
collections (so adding to linked collections is forbidden)
- `bpy collection.objects.link()` allows to add to linked collections
(should not be the case)
- `bpy collection.objects.link()` allows to add to overridden
collections (should not be the case)
While this might be supported in the future for overriden collections,
these cases should not be allowed atm. since objects get lost on file
reload.
Note: for the case of the `Object Properties` > `Collections` panel,
this could be improved further to filter out overridden collections as
well.

When auto-smooth enabled, but no custom normals layer present, the Alembic
exporter would incorrectly assume the mesh was shaded smooth. This is now
corrected, and normals are always written when auto-smooth is enabled.
Since the timeline is a variation of the dopesheet, it also respects
some of the dopesheet settings.
The "Selected Only" setting is overridden from a scene property (since
rB4904eadc0f38) and the "Display Hidden" dopesheet setting seems to be
ignored.
This commit adds the remaining "Show Errors" setting to the menu,
allowing it to be updated from the timeline.
Missing proper tagging of 'backward' pointer from fcurve to its group in

Issue was triggered by override, but crash could be generated from other

This removes grease pencil brush creation/dat-block delete on load,

Add assert to prevent this happening in the future

The previous code only handled the RGBA socket case. For vectors, we simply
use the average of the 3 compoments. This is done using a temp Vector Math
node using the dot operation.
Remove old code that added extra updates for shaders that have a dependency on
objects. The dependency graph can now tell Cycles when a material is affected by
an object transform.
This removes the smooth shading rendering from the face set overlay when
