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.

Cleanup: Add a copyright notice to files and use SPDX format 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 the only holder of the copyright in those files, and developers who do not have a signed contract with the foundation still hold the copyright as well. Another aspect of this change is using SPDX format for the header. We already used it for the license specification, and now we state it for the copyright as well, following the FAQ: https://reuse.software/faq/ 2023-05-31 16:19:06 +02:00			`*`

Revert file rename from T59773 fix Mixing file rename with other changes should be avoided. Using 'module_py_api' convention here is in keeping with imbuf, idprop, blf & bmesh. No reason for gpu to have a different convention. 2019-01-03 00:55:07 +11:00			`#pragma once`
Fix T59773: Raise exception if the gpu module is used in backgound mode. Instead of crashing, an error message is displayed if a function of the gpu module is called without a GPU context.

Refactor: Make header files more clangd and clang-tidy friendly When using clangd or running clang-tidy on headers there are currently many errors. These are noisy in IDEs, make auto fixes impossible, and break features like code completion, refactoring and navigation. This makes source/blender headers work by themselves, which is generally the goal anyway. But #includes and forward declarations were often incomplete. * Add #includes and forward declarations * Add IWYU pragma: export in a few places * Remove some unused #includes (but there are many more) * Tweak ShaderCreateInfo macros to work better with clangd Some types of headers still have errors, these could be fixed or worked around with more investigation. Mostly preprocessor template headers like NOD_static_types.h. Note that that disabling WITH_UNITY_BUILD is required for clangd to work properly, otherwise compile_commands.json does not contain the information for the relevant source files.

Cleanup: use nodiscard attribute for functions in the Python API In most (cases functions returning a PyObject pointer requires it to be used by the caller, declare functions in the Python API with the `nodiscard` attribute. 2025-06-28 00:15:23 +00:00			`[[nodiscard]] PyObject *BPyInit_gpu();`
