Negative indices that remained negative after adding the sequence length
caused incorrect slicing.
With the default scene for example:
bpy.context.scene.objects[-4:2]
Gave a different result to:
tuple(bpy.context.scene.objects)[-4:2]
Clamp indices above zero so loops that step forward works as intended.
Using BMesh operators through the edit-mesh API created a full copy
of the mesh so it was possible to restore the mesh in case
one of the operators raised an error.
Remove support for automatic backup/restore from the EDBM_op_* API's
as it adds significant overhead and was rarely used.
Operators that need this can use the BMBackup API to backup & restore
the mesh in case of failure.
Add warning levels to BMO_error_raise so operators can report problems
without it being interpreted as a request to cancel the operation.
For high-poly meshes creating and freeing a full copy is an expensive
operation, removing this gives a speedup of ~1.77x for most operators
except for "connect_verts" / "connect_vert_pair"
which still uses this functionality.
Avoid computationally expensive copying operations
when only some settings have been modified.
This is done by adding support for updating parameters
without tagging for copy-on-write.
Currently only mesh data blocks are supported,
other data-blocks can be added individually.
This prepares for changing values such as edit-mesh auto-smooth angle
in edit-mode without duplicating all mesh-data.
The benefit will only be seen when the user interface no longer tags
all ID's for copy on write updates.
ID_RECALC_GEOMETRY_ALL_MODES has been added to support situations
where non edit-mode geometry is modified in edit-mode.
While this isn't something user are likely to do,
Python scripts may change the underlying mesh.

Rename function EDBM_update_generic to EDBM_update, use a parameters
argument for better readability.
Also add calc_normals argument, which will have benefits when
calculating normals and tessellation together is optimized.
2 sided faces aren't supported and will cause problems in many areas
of Blender's code.
Removing (implied) support for faces with fewer than 3 sides
means the total number of triangles is known ahead of time.
This simplifies adding support for multi-threading and partial updates
to an existing tessellation - as the face and loop indices can be used
to access the range of triangles associated with a face.
Also correct outdated comments.
The deform parameter of the Bmesh from_object method is deprecated,
always assumed to be True, and will be removed in version 3.0.
That is because the cases where it is False don't work correctly and are
subject to memory leaks. One of the symptoms of the incorrect behavior
is the application of constructive modifiers twice if the input object
is an evaluated one, as demonstrated in D10053.

The Bmesh from_object method applies modifiers twice when the input
deform is enabled and the input depsgraph is a render one.
The evaluated object already have modifiers applied, and
mesh_create_eval_final() applies modifiers again. To fix this, the
BKE_mesh_new_from_object() function is used instead.

While `tp_print` was deprecated, Python 3.8+ uses this for
'tp_vectorcall_offset' which wasn't stated in the comment from
efd71aad4f.
Instead of suppressing clang-tidy, use preprocessor a check since
this properly represents the difference between Python versions.
This puts all generic float/int/vector/color/string geometry attributes in a new
.attributes property. For meshes it provides a more general API for existing
attributes, for point clouds attributes will be used as an essential part of
particle nodes.
This patch was implemented by @lichtwerk, with further changes by me. It's
still a work in progress, but posting here to show what is going on and for

This is for design task T67744, Boolean Redesign.
It adds a choice of solver to the Boolean modifier and the
Intersect (Boolean) and Intersect (Knife) tools.
The 'Fast' choice is the current Bmesh boolean.
The new 'Exact' choice is a more advanced algorithm that supports
overlapping geometry and uses more robust calculations, but is
slower than the Fast choice.
The default with this commit is set to 'Exact'. We can decide before
the 2.91 release whether or not this is the right choice, but this
choice now will get us more testing and feedback on the new code.
Functions `mesh_create_eval_final_view()` and
`mesh_create_eval_final_render()` were doing the exact same thing,
except for a hack introduced in d3eb9dddd6 (2012-10-08, Better fix for
T32846: dupligroup messes up particle instancing on rendering) that
appears to be no longer necessary. Besides that, these functions had
confusing names. Their functionality changed over time, and whether to
do for-render or for-viewport evaluation is now actually determined by
the depsgraph evaluation mode. This means that the `..._render` function
could evaluate a mesh with viewport settings, and vice versa.
The functions are now merged into `mesh_create_eval_final()`, and the
hack has been removed. The `OB_NO_PSYS_UPDATE` flag has been removed
entirely (instead of keeping it around as deprecated flag), because it
was always only temporarily set on objects during mesh evaluation and
thus not saved to the blend file.
No expected functional changes as far as users are concerned.
This replaces header include guards with `#pragma once`.
A couple of include guards are not removed yet (e.g. `__RNA_TYPES_H__`),
because they are used in other places.

This is related to T76659.
This just renames data type names to `CD_PROP_STRING`, `CD_PROP_FLOAT`
and `CD_PROP_INT32`. It makes them a bit more specific and removes

- Rename 'defvert_verify_index' to 'defvert_ensure_index'
since this adds the group if it isn't found.
