This commit adds the ability to generate liboverrides of linked data at
the `BKE_blendfile_link_append` BKE level, and through the Python API
(the `BPY_library_load` context manager, aka `bpy.data.libraries.load`).
The python API was updated essentially to allow easy testing of the new
code. This commit also adds tests for the new 'override' behavior, and
for existing basic link one.
Current code only generates 'basic' overrides, without any handing of
hierarchies or dependencies, as for brush assets only the Brush ID needs
to be overridden.
That new feature does not aim at being exposed to user through the
link/append operations in its current state, as it is way too simplistic.
This change is a requirement for the Brush Asset project (#101908).

GPUBatch.draw supports basic drawing methods. Although all
supported GPU backends support range based and instance based drawing.
This patch adds 2 methods to GPUBatch to add support to range based and
instance based drawing.
my_batch.draw_range(my_shader, elem_start=10, elem_count=5)
Will draw my_batch using my_shader. From the attached index buffer
elements 10-14 will be drawn.
my_batch.draw_instance_range(my_shader, instance_start=0, instance_count=10)
will draw my_batch using my_shader 10 times. Inside the vertex
shader the current instance number is held by gl_InstanceID.
Pull Request #104457
Names such as `dummyult` and `dummyet` didn't read very well,
underscore separate these names.
Also rename some variables that used old conventions which missed
being updated (`mpr` for manipulator instead of `gz` for gizmo).
For every other texture types this is expected to be implicitly
`GPU_DATA_FLOAT`. There is only one case where this is not the case.
I believe this was previously needed because the data type was
conditionning the texture creation. This is not the case anymore.
This commit implements described in the #104573.
The goal is to fix the confusion of the submodule hashes change, which are not
ideal for any of the supported git-module configuration (they are either always
visible causing confusion, or silently staged and committed, also causing
confusion).
This commit replaces submodules with a checkout of addons and addons_contrib,
covered by the .gitignore, and locale and developer tools are moved to the
main repository.
This also changes the paths:
- /release/scripts are moved to the /scripts
- /source/tools are moved to the /tools
- /release/datafiles/locale is moved to /locale
This is done to avoid conflicts when using bisect, and also allow buildbot to
automatically "recover" wgen building older or newer branches/patches.
Running `make update` will initialize the local checkout to the changed
repository configuration.
Another aspect of the change is that the make update will support Github style
of remote organization (origin remote pointing to thy fork, upstream remote
pointing to the upstream blender/blender.git).

This reverts commit 19222627c6.
Something went wrong here, seems like this commit merged the main branch
into the release branch, which should never be done.
This is a missing part of the Metal backend. Metal backend doesn't
support the bgl commands, but it was not possible to use the gpu
module to use scissor testing.
Without this change addon developers would not be able to migrate
their addons to support the Metal backend.
This patch adds:
- `gpu.state.scissor_set`
- `gpu.state.scissor_get`
- `gpu.state.scissor_test_set`
Fix#104911
This better aligns with OSX/Linux warnings.
Although `__pragma(warning(suppress:4100))` is not the same as
`__attribute__((__unused__))` in gcc (which only affects the attribute
instead of the line), it still seems to be better to use it than to
hide the warning entirely.
Documented all functions, adding use case and side effects.
Also replace the use of shortened argument name by more meaningful ones.
Renamed `GPU_batch_instbuf_add_ex` and `GPU_batch_vertbuf_add_ex` to remove
the `ex` suffix as they are the main version used (removed the few usage
of the other version).
Renamed `GPU_batch_draw_instanced` to `GPU_batch_draw_instance_range` and
make it consistent with `GPU_batch_draw_range`.
Added missing documentation for `draw_cursor_add` and
`draw_cursor_remove` methods for `WindowManager`.

BGL deprecation calls used to be reported on each use. As bgl calls
are typically part of a handler that is triggered at refresh this
could lead to overflow of messages and slowing down systems when
the terminal/console had to be refreshed as well.
This patch only reports the first 100 bgl deprecation calls. This
gives enough feedback to the developer that changes needs to be made
. But still provides good responsiveness to users when they have
such add-on enabled. Only the first frames can have a slowdown.
User site-packages were disabled unless `--python-use-system-env`
argument was given. This was done to prevent Blender's Python
unintentionally using modules that happened to be installed locally,
however it meant so pip installing modules from Blender would fail to
load those modules (for some users).
Enable user site-packages since it's needed for installing additional
packages via pip, see code-comments for details.
Resolves T104000.
Goal of this patch is to stop the invocation of OpenGL calls via the bgl module
on a none OpenGL GPU backend, report this as a python deprecation warning
and report this to the user.
## Deprecation warning to developers
```
>>> import bgl
>>> bgl.glUseProgram(0)
<blender_console>:1: DeprecationWarning: 'bgl.glUseProgram' is deprecated and will be removed in Blender 3.7. Report or update your script to use 'gpu' module.
```
## Deprecation message to users
The message to the user is shown as part of the Info Space and as a message box.
{F14159203 width=100%}
{F14158674 width=100%}
During implementation we tried several ideas:
# Use python warning as errors: This isn't fine grained enough and can show incorrect information to the user.
# Throw deprecation as error and use sys.excepthook to report the user message.
This required a custom exception class to identify the bgl deprecation and a CPython handler function to
be set during python initialization. Although this is the most flexible there was a disconnect between the
exception class, exception function and the excepthook registration.
# A variant how we handle autoexec failures. A flag is stored in Global and when set the user message is reported.
Not that flexible, but code is more connected to the boolean stored in the Global struct.
Although using Global struct isn't nice I chose this solution due to its traceability. It is clear to developers
reading the code how the mechanism works by using search all functionality of your IDE.

Use a consistent style for declaring the names of struct members
in their declarations. Note that this convention was already used in
many places but not everywhere.
Remove spaces around the text (matching commented arguments) with
the advantage that the the spell checking utility skips these terms.
Making it possible to extract & validate these comments automatically.
Also use struct names for `bAnimChannelType` & `bConstraintTypeInfo`
which were using brief descriptions.
A proper boolean custom property type is commonly requested. This
commit simply adds a new `IDP_BOOLEAN` type that can be used for
boolean and boolean array custom properties. This can also be used
for exposing boolean node sockets in the geometry nodes modifier.
I've just extended the places existing IDProperty types are used, and
tested with the custom property edit operator and the python console.
Adding another IDProperty type is a straightforward extension of the
existing design.

Currently the `MLoopUV` struct stores UV coordinates and flags related
to editing UV maps in the UV editor. This patch changes the coordinates
to use the generic 2D vector type, and moves the flags into three
separate boolean attributes. This follows the design in T95965, with
the ultimate intention of simplifying code and improving performance.
Importantly, the change allows exporters and renderers to use UVs
"touched" by geometry nodes, which only creates generic attributes.
It also allows geometry nodes to create "proper" UV maps from scratch,
though only with the Store Named Attribute node for now.
The new design considers any 2D vector attribute on the corner domain
to be a UV map. In the future, they might be distinguished from regular
2D vectors with attribute metadata, which may be helpful because they
are often interpolated differently.
Most of the code changes deal with passing around UV BMesh custom data
offsets and tracking the boolean "sublayers". The boolean layers are
use the following prefixes for attribute names: vert selection: `.vs.`,
edge selection: `.es.`, pinning: `.pn.`. Currently these are short to
avoid using up the maximum length of attribute names. To accommodate
for these 4 extra characters, the name length limit is enlarged to 68
bytes, while the maximum user settable name length is still 64 bytes.
Unfortunately Python/RNA API access to the UV flag data becomes slower.
Accessing the boolean layers directly is be better for performance in
general.
Like the other mesh SoA refactors, backward and forward compatibility
aren't affected, and won't be changed until 4.0. We pay for that by
making mesh reading and writing more expensive with conversions.

**Changes**
As described in T93602, this patch removes all use of the `MVert`
struct, replacing it with a generic named attribute with the name
`"position"`, consistent with other geometry types.
Variable names have been changed from `verts` to `positions`, to align
with the attribute name and the more generic design (positions are not
vertices, they are just an attribute stored on the point domain).
This change is made possible by previous commits that moved all other
data out of `MVert` to runtime data or other generic attributes. What
remains is mostly a simple type change. Though, the type still shows up
859 times, so the patch is quite large.
One compromise is that now `CD_MASK_BAREMESH` now contains
`CD_PROP_FLOAT3`. With the general move towards generic attributes
over custom data types, we are removing use of these type masks anyway.
**Benefits**
The most obvious benefit is reduced memory usage and the benefits
that brings in memory-bound situations. `float3` is only 3 bytes, in
comparison to `MVert` which was 4. When there are millions of vertices
this starts to matter more.
The other benefits come from using a more generic type. Instead of
writing algorithms specifically for `MVert`, code can just use arrays
of vectors. This will allow eliminating many temporary arrays or
wrappers used to extract positions.
Many possible improvements aren't implemented in this patch, though
I did switch simplify or remove the process of creating temporary
position arrays in a few places.
The design clarity that "positions are just another attribute" brings
allows removing explicit copying of vertices in some procedural
operations-- they are just processed like most other attributes.
**Performance**
This touches so many areas that it's hard to benchmark exhaustively,
but I observed some areas as examples.
* The mesh line node with 4 million count was 1.5x (8ms to 12ms) faster.
* The Spring splash screen went from ~4.3 to ~4.5 fps.
* The subdivision surface modifier/node was slightly faster
RNA access through Python may be slightly slower, since now we need
a name lookup instead of just a custom data type lookup for each index.
**Future Improvements**
* Remove uses of "vert_coords" functions:
* `BKE_mesh_vert_coords_alloc`
* `BKE_mesh_vert_coords_get`
* `BKE_mesh_vert_coords_apply{_with_mat4}`
* Remove more hidden copying of positions
* General simplification now possible in many areas
* Convert more code to C++ to use `float3` instead of `float[3]`
* Currently `reinterpret_cast` is used for those C-API functions

Translation from python enum values were incorrect and textures created
in python using those types would result in faulty textures. In
renderdoc those textures would not bind.
`BPYGPU_IS_INIT_OR_ERROR_OBJ` is not implemented in all pygpu functions.
Instead of copying and pasting that call across the API when it has no
gpu context, override the methods with one that always reports error.
The new Xcode 14.1 brings the new Apple Clang compiler which
considers sprintf unsafe and geenrates deprecation warnings
suggesting to sue snprintf instead. This only happens for C++
code by default, and C code can still use sprintf without any
warning.
This changes does the following:
- Whenever is trivial replace sprintf() with BLI_snprintf.
- For all other cases use the newly introduced BLI_sprintf
which is a wrapper around sprintf() but without warning.
There is a discouragement note in the BLI_sprintf comment to
suggest use of BLI_snprintf when the size is known.
