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.
Registering a property could remove the existing property,
then fail to parse one of the arguments of the new property -
leaving the struct without a property.
Now freeing the existing property is deferred until immediately
before the new property is registered.
- Use `default` instead of `def` abbreviation.
- Rename `BPYPropArrayLength` to `BPyPropArrayLength`
in keeping with other local structs.
- Remove _PyArg_Parser.fname value accidentally left in
(harmless as it's not used).
Macros were used for expanding shared logic for some properties.
Replace this with Python converters & a funciton that handles
deferred registration.
Add generic converter functions for RNA enums:
- pyrna_enum_value_parse_string
- pyrna_enum_bitfield_parse_set
- Multi-dimensional boolean, int and float vector types are supported.
- A sequence of int's for the "size" is used to declare dimensions.
- Nested sequences are required for default arguments.
Now it's possible to define matrix properties, for e.g:
bpy.props.FloatVectorProperty(size=(4, 4), subtype='MATRIX')
Add array conversion functions that take dimension arguments.
- PyC_AsArray_Multi (version of PyC_AsArray).
- PyC_Tuple_PackArray_Multi_* (version of PyC_Tuple_Pack_*).
Failure to return a list of the expected size & type wasn't
decrementing the value, leaking a reference.
Caused by 127b5423d6 a workaround for the
real error that was fixed f5e020a7a6.
On Windows, using `bpy.data.orphans_purge` with some arguments (eg: `do_recursive=True`) does not produce the expected results. This is due to arguments not being parsed correctly on this platform with the current code.
The proposed fix is based on how other functions with boolean attributes are exposed to the Python API.

Some uses of delaunay_2d_calc don't need to know the original verts,
edges, and faces that correspond to output elements.
This change adds a "need_ids" value to the CDT input spec, default true,
which tracks the input ids only when true.
The python api mathutils.geometry.delaunay_2d_cdt gets an optional
final bool argument that is the value of need_ids. If the argument
is not supplied, it is true by default, so this won't break old uses
of the API.
On a sample text test, not tracking ids save about 30% of the runtime.
For most inputs the difference will not be so dramatic: it only really
kicks in if there are a lot of holes.
The `__enter__` function of the `bpy.data.libraries.load` context manager
was storing a pointer to a stack-allocated variable, which was subsequently
used in the `__exit__` function, causing a crash. This is now fixed.
Thanks @Severin for the patch.
This adds id_properties_clear() and id_properties_ensure() functions
to RNA structs. This is meant as an initial change based on discussion
in review of D9697. However, they may be useful in other situations.
The change requires refactoring the internal idproperties callback to
return a pointer to the IDProperty pointer, which actually turns out
to be quite a nice cleanup.
An id_properties attribute could be added in the future potentially.

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.

This reverts commit rB3a48147b8ab92, and fixes the issues with linking
etc.
Change compared to previous buggy commit (rBf8d219dfd4c31) is that
new `BlendFileReadReports` reports are now passed to the lowest level
function generating the `FileData` (`filedata_new()`), which ensures
(and asserts) that all code using it does have a valid non-NULL pointer
to a `BlendFileReadReport` data.
Sorry for the noise, it's always when you think a change is trivial and
do not test it well enough that you end up doing those kind of
mistakes...
