The problem was that nullptr was returned which is a valid value for
Mesh * and hence the returned optional was treated as having some value.
There was no check for point clouds so that was fixed as well.

Fixes T95384. New exporter was missing a fix for T94516 that recently got applied to the python exporter.
Also changed the obj export tests code so that when save_failing_test_output is requested and MTL result is different from the golden expectation, it is saved as well, similar to how it's done for the OBJ file result.
Caused by rBf75449b5f2b04b79, which was missing a null check when
attempting to extract a `CustomData` pointer from an mesh that might
be null if the object isn't a mesh object. The commit added null checks
elsewhere, so simply adding them here is a straightforward fix.
Fixes T95526, T95539
The new wavefront .obj exporter in 3.1 was producing slightly invalid parm line syntax (missing u), and was not setting first/last N params to zeroes and ones for curves with "endpoint" flag properly.
Since we have a node that sets a mesh's auto smooth angle
(unfortunately, in retrospect), we generally can't assume at all
that value is the same as whatever input mesh. Similar asserts
were removed previously in 8216b759e9. While the attempt
at assertions to clarify assumptions is noble, this one doesn't
make sense anymore.
I found this while investigating T95479.

Detected on `amdgpu-pro` libGL implementation. The workaround is to not
use explicit location for vertex attributes. This is not a real problem
as we don't rely on them for now.
This was an oversight in the patch that added this node,
the default merge distance is meant to be the same as the weld
modifier, 0.001m, meaning by in most situations it removes
vertices generally at the same location.
The check for existence of custom data layers did not take wrapper nature of
mesh into account.
Quickest and safest for 3.1 solution is to take care of branching of checks
in the draw manager.
Ideally both wrapper and mesh access will happen via the same public API
without branching in the "user" code. That is something outside of the fix
for the coming release though.

Byte images are converted to float. Due to an issue how VSE cache is
freeing its images we cannot store these float buffers what leads
to recalculating it for each change in the image editor.
This fix will reduce the slowdown to areas that have the root cause of
the memory leak, so the buffers can be reused between refreshes.
NOTE: The root cause should still be fixed.
Thanks for reporting Sybren!
This was caused by macros interpreted as recursive. Workaround by
not using macros at all and just define local variables which
hopefully will be optimized.
Crash introduced by {rB0cb5eae}.
When switching to between drawing modes the region.draw_buffer could be
uninitialized when the gizmo depth test is performed. When the mouse is
placed on top of a gizmo part that could be highlighted would crash.
This fix adds a early exit when depth testing is requested, but there
isn't a draw_buffer. Not sure this is an root cause fix.
Reported by multiple animators in Blender Studio.
Technically, this can't be relied upon in the long term. It worked more or
less accidentally before. It was broken by a previous fix accidentally. I mainly
bring it back because rBa985f558a6eb16cd6f0 was not expected to have
this side effect.
Note, this change can result in slower performance. Writing to a vertex
groups is less efficient than using a generic attribute.
When viewing backdrop on top of the node grid, the grid would be
rendered black when the mode wasn't set to RGBA. This fix fixes this by
reverting the previous fix of drawing the backdrop and implement a
different one that recomputes the UV coordinates on the screen edges.
ED_transverts_create_from_obedit expected an evaluated object.
Add flag to request TX_VERT_USE_MAPLOC to be set, which avoids having to
calculate this data when it's not used as well as the requirement
that the input object be evaluated from the depsgraph.
Iterating over scene's objects while we modify those (through proxy to
override conversion code) is call for problems (use after free etc.).
Instead, all proxy objects need to be gathered first in a temporary
list, and processed all at once in a second loop.
`BKE_collection_object_add` ensures given object is added to an editable
collection, and not e.g. a linked or override one.
However, some processes like do_version manipulate collections also from
libraries, i.e. linked collections, in those cases we need a version of
the code that unconditionnally adds the given object to the given
colleciton.
This is from patch D13988. It removes the "- New" from the menu of the
new obj exporter, changes the default addon to just io_import_obj,
and does the right versioning thing.
Also disables the python tests for the old python exporter.
Those cases are fairly hard to track down... Added some more checks,
also at lower levels, more generic levels of object editing, and fixed
core check in liboverride (previously code was assuming that an override
of a collection only could have overrides of objects or linked objects,
but this is not necessarily true).
Use the ID.recalc flag to detect when updates after frame-change is
needed. Since comparing the last calculated frame doesn't take undo into
account (see code-comment for details).
`ID_RECALC_AUDIO_SEEK` has been renamed to `ID_RECALC_FRAME_CHANGE`
since this is not only related to audio however internally this flag is
still categorized in `NodeType::AUDIO`.

The issue was happening with a specific file where the ID management
code was not fully copying all modifiers because of the extra check
in the `BKE_object_support_modifier_type_check()`.
While it is arguable that copy-on-write should be a 1:1 copy there is
no real need to maintain the per-modifier pointer to its original.
Use its SessionUUID to perform lookup in the original datablock.
Downside of this approach is that it is a linear lookup instead of
direct pointer access, but the upside is that there is less pointers
to manage and that the file with unsupported modifiers does behave
correct without any asserts.

The modifiers are mapped between original and evaluated objects based on
their session IDs. The pointer to original modifier is no longer needed
for the backup: it remained from the initial implementation which was
rewritten at some point.
This is a preparation for removal of the pointer to original modifier.
Part of the resynching code would access collections' objects base
cache, which can be invalid at that point (due to previous ID remapping
and/or deletion). Use a custom recursive iterator over collections'
objects instead, since those 'raw' data like collection's objects list,
and collection's children lists, should always be valid.
Found while investigating a studio production file.
This is a temp fix for a memory leak where the VSE isn't aware that a
float representation of the image could exist. The VSE somehow doens't
clears it (refcounter is still 1).
The work around is just to let the image engine clean up all the data it
created. Potential this would add more overhead when buffers are needed
more than once.
This refactors how output attributes are computed in the geometry
nodes modifier. Previously, all output attributes were computed one
after the other. Every attribute was stored on the geometry directly
after computing it. The issue was that other output attributes might
depend on the already overwritten attributes, leading to unexpected
behavior.
The solution is to compute all output attributes first before changing the
geometry. Under specific circumstances, this refactor can result in a speedup,
because output attributes on the same domain are evaluated together now.
Overwriting existing might have become a bit slower, because we write the
attribute into new buffer instead of using the existing one.

Mistake in the 974981a637: f the edit data is not present then the
origindex codepath is to be used. Added a brief note about it on the
top of the file.
More ideally would be to remove edit mesh from non-bmesh-wrappers
but this would require changes in the draw manager to make a proper
decision about drawing edit mode overlays.
Function `IMB_indexer_get_seek_pos()` can return non 0 seek position for
frame index 0. This causes seeking to incorrect GOP and scanning ends
with failiure.
Hard-code first frame index seek position to 0.

If an entire cyclic stroke was selected, calling "Separate by Points"
would leave a gap in the new object (making the new stroke non-cyclic).
The patch makes sure that if we separate by points and all points are
selected, we fall back to separate by stroke.
