e955c94ed3 License Headers: Set copyright to "Blender Authors", add AUTHORS
Listing the "Blender Foundation" as copyright holder implied the Blender
Foundation holds copyright to files which may include work from many
developers.

While keeping copyright on headers makes sense for isolated libraries,
Blender's own code may be refactored or moved between files in a way
that makes the per file copyright holders less meaningful.

Copyright references to the "Blender Foundation" have been replaced with
"Blender Authors", with the exception of `./extern/` since these this
contains libraries which are more isolated, any changed to license
headers there can be handled on a case-by-case basis.

Some directories in `./intern/` have also been excluded:

- `./intern/cycles/` it's own `AUTHORS` file is planned.
- `./intern/opensubdiv/`.

An "AUTHORS" file has been added, using the chromium projects authors
file as a template.

4ea2baf4ae CMake: revert last weeks modernizations
The cleanup of blenkernel last weeks , caused the house of cards to
collapse on  top of bf_gpu's shader_builder, which is off by default
but used on a daily basis by the rendering team.

Given the fixes forward in #110394 ran into a ODR violation in OSL that
was hiding there for years, I don't see another way forward without
impeding the rendering teams productivity for "quite a while" as there
is no guarantee the OSL issue would be the end of it.

the only way forward appears to be back.

7cebb61486 Cleanup: CMake: Modernize bf_dna dependencies
There's quite a few libraries that depend on dna_type_offsets.h
but had gotten to it by just adding the folder that contains it to
their includes INC section without declaring a dependency to
bf_dna in the LIB section.

which occasionally lead to the lib building before bf_dna and the
header being missing, while this generally gets fixed in CMake by
adding bf_dna to the LIB section of the lib, however until last
week all libraries in the LIB section were linked as INTERFACE so
adding it in there did not resolve the build issue.

To make things still build, we sprinkled add_dependencies wherever
we needed it to force a build order.

This diff :

Declares public include folders for the bf_dna target so there's
no more fudging the INC section required to get to them.

Removes all dna related paths from the INC section for all
libraries.

Adds an alias target bf:dna to signify it has been updated to
modern cmake

Declares a dependency on bf::dna for all libraries that require it

Removes (almost) all calls to add_dependencies for bf_dna

Future work:

Because of the manual dependency management that was done, there is
now some "clutter" with libs depending on bf_dna that realistically
don't. Example bf_intern_opencolorio itself has no dependency on
bf_dna at all, doesn't need it, doesn't use it. However the
dna include folder had been added to it in the past since bf_blenlib
uses dna headers in some of its public headers and
bf_intern_opencolorio does use those blenlib headers.

Given bf_blenlib now correctly declares the dependency on bf_dna
as public bf_intern_opencolorio will get the dna header directory
automatically from CMake, hence some cleanup could be done for
bf_intern_opencolorio

Because 99% of the changes in this diff have been automated, this diff
does not seek to address these issues as there is no easy way to
determine why a certain dependency is in place. A developer will have
to make a pass a this at some later point in time. As I'd rather not
mix automated and manual labour.

There are a few libraries that could not be automatically processed
(ie bf_blendthumb) that also will need this manual look-over.

A lot of files were missing copyright field in the header and
the Blender Foundation contributed to them in a sense of bug
fixing and general maintenance.

This change makes it explicit that those files are at least
partially copyrighted by the Blender Foundation.

Note that this does not make it so the Blender Foundation is

who do not have a signed contract with the foundation still

cac6b6f388 BGL_Wrap: disable calls on non-opengl backends.
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.

8ffc11dbcb Cleanup OpenGL linking and related code after libepoxy merge
This cleans up the OpenGL build flags and linking.
It additionally also removes some dead code.

One of these dead code paths is WITH_X11_ALPHA which actually never was
active even with the build flag on. The call to use this was never
called because the default initializer for GHOST was set to have it off
per default. Nothing called this function with a boolean value to enable it.

These cleanups are needed to support true headless OpenGL rendering.
Without these cleanups libepoxy will fail to load the correct OpenGL
Libraries as we have already linked them to the blender binary.

a296b8f694 GPU: replace GLEW with libepoxy
With libepoxy we can choose between EGL and GLX at runtime, as well as
dynamically open EGL and GLX libraries without linking to them.

This will make it possible to build with Wayland, EGL, GLVND support while
still running on systems that only have X11, GLX and libGL. It also paves
the way for headless rendering through EGL.

libepoxy is a new library dependency, and is included in the precompiled
libraries. GLEW is no longer a dependency, and WITH_SYSTEM_GLEW was removed.

Previously GPU_backend_init was called indirectly from
DRW_opengl_context_create, a new function is now called from the window

has a back-end.

This also disables the `bgl` Python module when building WITH_HEADLESS.

8b9a3b94fc Refactor IDProperty UI data storage
The storage of IDProperty UI data (min, max, default value, etc) is
quite complicated. For every property, retrieving a single one of these
values involves three string lookups. First for the "_RNA_UI" group
property, then another for a group with the property's name, then for
the data value name. Not only is this inefficient, it's hard to reason
about, unintuitive, and not at all self-explanatory.

This commit replaces that system with a UI data struct directly in the
IDProperty. If it's not used, the only cost is of a NULL pointer. Beyond
storing the description, name, and RNA subtype, derived structs are used
to store type specific UI data like min and max.

Note that this means that addons using (abusing) the `_RNA_UI` custom
property will have to be changed. A few places in the addons repository
will be changed after this commit with D9919.

**Before**
Before, first the _RNA_UI subgroup is retrieved the _RNA_UI group,
then the subgroup for the original property, then specific UI data
is accessed like any other IDProperty.
```
prop = rna_idprop_ui_prop_get(idproperties_owner, "prop_name", create=True)
prop["min"] = 1.0
```

**After**
After, the `id_properties_ui` function for RNA structs returns a python
object specifically for managing an IDProperty's UI data.
```
ui_data = idproperties_owner.id_properties_ui("prop_name")
ui_data.update(min=1.0)
```
In addition to `update`, there are now other functions:
 - `as_dict`: Returns a dictionary of the property's UI data.
 - `clear`: Removes the property's UI data.
 - `update_from`: Copy UI data between properties,
   even if they have different owners.

517870a4a1 CMake: Refactor external dependencies handling
This is a more correct fix to the issue Brecht was fixing in D6600.

While the fix in that patch worked fine for linking it broke ASAN
runtime under some circumstances.
For example, `make full debug developer` would compile, but trying
to start blender will cause assert failure in ASAN (related on check
that ASAN is not running already).

Top-level idea: leave it to CMake to keep track of dependency graph.

The root of the issue comes to the fact that target like "blender" is
configured to use a lot of static libraries coming from Blender sources
and to use external static libraries. There is nothing which ensures
order between blender's and external libraries. Only order of blender
libraries is guaranteed.

It was possible that due to a cycle or other circumstances some of
blender libraries would have been passed to linker after libraries
it uses, causing linker errors.

For example, this order will likely fail:

  libbf_blenfont.a libfreetype6.a libbf_blenfont.a

This change makes it so blender libraries are explicitly provided
their dependencies to an external libraries, which allows CMake to
ensure they are always linked against them.

General rule here: if bf_foo depends on an external library it is
to be provided to LIBS for bf_foo.
For example, if bf_blenkernel depends on opensubdiv then LIBS in
blenkernel's CMakeLists.txt is to include OPENSUBDIB_LIBRARIES.

The change is made based on searching for used include folders
such as OPENSUBDIV_INCLUDE_DIRS and adding corresponding libraries
to LIBS ion that CMakeLists.txt. Transitive dependencies are not
simplified by this approach, but I am not aware of any downside of
this: CMake should be smart enough to simplify them on its side.
And even if not, this shouldn't affect linking time.

Benefit of not relying on transitive dependencies is that build
system is more robust towards future changes. For example, if
bf_intern_opensubiv is no longer depends on OPENSUBDIV_LIBRARIES
and all such code is moved to bf_blenkernel this will not break
linking.

The not-so-trivial part is change to blender_add_lib (and its
version in Cycles). The complexity is caused by libraries being
provided as a single list argument which doesn't allow to use
different release and debug libraries on Windows. The idea is:

- Have every library prefixed as "optimized" or "debug" if
  separation is needed (non-prefixed libraries will be considered
  "generic").

- Loop through libraries passed to function and do simple parsing
  which will look for "optimized" and "debug" words and specify
  following library to corresponding category.

This isn't something particularly great. Alternative would be to
use target_link_libraries() directly, which sounds like more code
but which is more explicit and allows to have more flexibility
and control comparing to wrapper approach.

Tested the following configurations on Linux, macOS and Windows:

- make full debug developer
- make full release developer
- make lite debug developer
- make lite release developer

NOTE: Linux libraries needs to be compiled with D6641 applied,
otherwise, depending on configuration, it's possible to run into
duplicated zlib symbols error.

f95d7c9e66 patch [#29421] Python Noise Module Updates
from Andrew Hale (trumanblending)

Tracker description
*******************

The current python noise module included with Blender has yet to be updated to the new Py API. This patch does so, with the following major points:

- The noise module has now been moved to a submodule of mathutils, it can be accessed by mathutils.noise. It was moved from it's own module as it will now return mathutils types and also have greater visibility to the user.
- All functions which return vectors will now return mathutils.Vector types to be consistent with the rest of the API. Previously (x, y, z) tuples were returned.
- A different implementation of random_unit_vector is now used, this allows 2D, 3D and 4D vectors to be returned. Previously only 3D was possible.
- Some function names have been changed to remove ambiguities and make naming consistent within the module. noise.vector is now noise.noise_vector and noise.vl_vector is now noise.variable_lacunarity
- Doc strings have been updated to be compatible with auto docs.
- Code style and internal naming has been changed to match the conventions in other mathutils code.

Thanks,
Andrew

d4d80ee0a1 rename IDProp.c/h to idprop_py_api, since it was same name as BKE idprop.c with case changed. 2011-11-15 09:28:15 +00:00
