Accessing `__class__` on a removed object raised an exception, making
`isinstance(ob, cls)` unreliable. Always allow class access.
Resolves issue raised by blender/blender-addons!104958.
When restoring a temporary context, account for changes to the context
made by actions (typically operators) in the script.
There was an incorrect assumption that an override which didn't change
the current context would also be unchanged when restoring the temporary
context's original values.
- Use FunctionRef to avoid passing a separate user_data pointer
- Use std::string in arguments struct
- Add search items in one loop after gathering search items
- Use Vector of unique_ptr for search items instead of linked list
Add a new `BKE_lib_query_unused_ids_amounts` to query expected amounts
of deleted IDs. This function does not tag IDs in main anymore.
Factorize most parameters (and output data) into a new struct
`LibQueryUnusedIDsData`.
Part of PR https://projects.blender.org/blender/blender/pulls/117304.
I added a new BLO_userdef_default.h header to contain declarations of
two global variables that are still defined in C files. Use of designated
initializers for large structs make those files harder to change.
Arguably this is a better header for them anyway.

Writing Style guide).

- Use MULTIPLICATION SIGN U+00D7 instead of MULTIPLICATION X U+2715.
- "LClick" -> "LMB", "RClick" -> "RMB": this convention is used
everywhere else.
- "Save rendered the image..." -> "Save the rendered image...": typo.
- "Preserve Current retiming": title case for property.
- Bend status message: punctuation.

This significantly simplifies memory management, mostly by avoiding
the need to free the memory manually. It may also improve performance,
since std::string has an inline buffer that can prevent heap
allocations and it stores the size.

The term `PIL` stands for "platform independent library." It exists since the `Initial Revision`
commit from 2002. Nowadays, we generally just use the `BLI` (blenlib) prefix for such code
and the `PIL` prefix feels more confusing then useful. Therefore, this patch renames the
`PIL` to `BLI`.

No functional changes expected.
Before this PR the keyframing code was aware of driver specifics
and changed the frame where a key is inserted to the current driver value.
This is now changed so that the calling code needs to know where on the
FCurve the key should be inserted. This removes the need for the
`INSERTKEY_DRIVER` flag.

The FPS menu was using a cached value which wasn't being refreshed
when translation changed.
Add `bpy.app.handlers.translation_update_post` handler which runs
when translation changes, this can be used to clear any cached UI
values.
Ref !117049
Using screen changing functions with screens used for full screen areas
isn't supported & caused corrupt screen data.
Add checks that the current and overriding screen support switching,
raising an error when they don't. Also add a check when restoring the
context not to change any full screen areas.
Recent and ongoing efforts have changed many properties to be stored
contiguously in memory, e.g. mesh attributes. This patch updates
rna_raw_access to make use of this and copy the entire contiguous block
of memory when the property is stored contiguously.
This is faster and scales much better with larger arrays.
Pull Request: https://projects.blender.org/blender/blender/pulls/116015
The foreach_get/foreach_set methods of bpy_prop_array get/set the entire
contents of the array, but they were checking that the length of the
input sequence was equal to the length of the current array dimension
rather than the total length of all dimensions of the array.
This would read/write memory after the end of the passed in sequence
when the property was a multidimensional array. Performing
`foreach_get` with a Python list with length matching the length of the
current dimension of a multidimensional array would crash a debug build
due to the trailing pad bytes of the temporarily allocated array being
overwritten.
This patch fixes `pyprop_array_foreach_getset` by changing the function
used to get the expected sequence size, to the RNA function that gets
the total length of the array across all its dimensions.
The tests have be updated to additionally test multidimensional array
properties.

Translation of the UI is currently split into 3 preferences:
interface, tooltips, and new data. The distinction between interface
and tooltips is currently unclear as tooltips also include a lot of
messages not displayed in the actual tooltips on mouse hover.
These include reports to the Info Editor, information in editor
headers and footers, and statuses in panels.
In order to limit the use of `TIP_()` to actual tooltips, this commit
introduces a new preference for this extra information: "Reports".
New translation macros are introduced: `RPT_()` and `CTX_RPT_()`, as
well as their equivalent for the Python API, `pgettext_rpt_()`, to be
imported as `rpt_()`.

RNA raw types were missing for the int8_t, uchar (uint8_t),
ushort (uint16_t), int64_t and uint64_t DNA types types.
This adds the missing RNA raw types for all DNA types that can have
raw access.
Functional Changes
Properties with one of the new unsigned raw types will raise a Python
OverflowError in foreach_getset when attempting to read a negative
integer from bpy_prop_collection.foreach_set(). This is similar to the
existing behaviour of providing a Python int which is too large to
represent as a C long. The existing foreach_getset code will print
the OverflowError and then raise a TypeError instead.
CPython's signed integer parsing functions accept numeric types that are
not the Python int instances by calling their __index__() method.
CPython's unsigned integer parsing functions, however, only accept
Python int instances. To make foreach_getset accept the same
numeric types for unsigned raw types as it already accepts for signed
raw types, the unsigned integer parsing functions in py_capi_utils.h
have been updated to also call the __index__() method when given an
argument which is not a Python int instance.
Because the new unsigned integer parsing in foreach_getset is using
the PyC_ family of functions, which perform their own overflow checks,
the existing signed integer parsing has also been updated to use the
PyC_ family of functions for signed integer parsing. Previously,
OverflowError would only have been raised when the parsed integer was
too large to fit in a C long. With this patch, OverflowError will be
raised whenever the parsed integer is too large to fit in the property's
raw type. Integer properties already have well-defined maximum and
minimum values which should fit within the property's raw type, and enum
properties have a fixed number of values they can take depending on
their items. The bigger change here, is that setting bool properties
which use PROP_RAW_BOOLEAN will now only accept 0/False and
1/True.
Now that PROP_RAW_CHAR parsing is using PyC_Long_AsU8,
signed char buffers ("b" format) have been updated to no longer be
considered compatible with PROP_RAW_CHAR, matching the behaviour of
the other unsigned types only being considered compatible with unsigned
buffer formats.
The int64_t and uint64_t types can currently only be used by bool
properties (see IS_DNATYPE_BOOLEAN_COMPAT and the other macros in
RNA_define.hh), but bool properties only have raw access when they do
not use a bitmask and it doesn't make much sense to use an entire 64
bits just for a single bool property, so PROP_RAW_INT64 and
PROP_RAW_UINT64 are expected to be unused.
Performance Changes
Providing raw types allows for faster access through
rna_access.cc#rna_raw_access, especially when a buffer compatible with
the property's raw type is passed through from
bpy_rna.cc#foreach_getset.
Before this patch, the bpy.types.Keyframe.handle_left_type property
did not have raw access, so foreach_getset would fall back to
PROP_RAW_INT being the compatible type and then use the slower loop in
rna_raw_access.
With this patch, the bpy.types.Keyframe.handle_left_type property has
raw access with the PROP_RAW_UINT8 type. Using a buffer compatible
with this raw type can use the faster memcpy loop in
rna_raw_access. Using a Python list will iterate the list into an
array whose type matches PROP_RAW_UINT8, which will also use the
faster memcpy loop in #rna_raw_access.
