2022-02-11File headers: SPDX License migrationCampbell Barton
Use a shorter/simpler license convention, stops the header taking so much space. Follow the SPDX license specification: https://spdx.org/licenses - C/C++/objc/objc++ - Python - Shell Scripts - CMake, GNUmakefile While most of the source tree has been included - `./extern/` was left out. - `./intern/cycles` & `./intern/atomic` are also excluded because they use different header conventions. doc/license/SPDX-license-identifiers.txt has been added to list SPDX all used identifiers. See P2788 for the script that automated these edits. Reviewed By: brecht, mont29, sergey Ref D14069
2021-12-07Cleanup: move public doc-strings into headers for 'blenkernel'Campbell Barton
- Added space below non doc-string comments to make it clear these aren't comments for the symbols directly below them. - Use doxy sections for some headers. - Minor improvements to doc-strings. Ref T92709
2021-11-29Refactor BKE_bpath module.Bastien Montagne
The main goal of this refactor is to make BPath module use `IDTypeInfo`, and move each ID-specific part of the `foreach_path` looper into their own IDTypeInfo struct, using a new `foreach_path` callback. Additionally, following improvements/cleanups are included: * Attempt to get better, more consistent namings. ** In particular, move from `path_visitor` to more standard `foreach_path`. * Update and extend documentation. ** API doc was moved to header, according to recent discussions on this topic. * Remove `BKE_bpath_relocate_visitor` from API, this is specific callback that belongs in `lib_id.c` user code. NOTE: This commit is expected to be 100% non-behavioral-change. This implies that several potential further changes were only noted as comments (like using a more generic solution for `lib_id_library_local_paths`, addressing inconsistencies like path of packed libraries always being skipped, regardless of the `BKE_BPATH_FOREACH_PATH_SKIP_PACKED` `eBPathForeachFlag` flag value, etc.). NOTE: basic unittests were added to master already in rBdcc500e5a265093bc9cc. Reviewed By: brecht Differential Revision: https://developer.blender.org/D13381
2021-11-24Cleanup: `IDTypeInfo` new `asset_type_info` member.Bastien Montagne
Two issues addressed here: I) `asset_type_info` is sub-data, not a callback. Therefore, move it before the callbacks in the `IDTypeInfo` struct. II) More important, initialize this new attribute in *ALL* `IDTypeInfo` instances. No member of this struct should ever be left implicitely uninitilazed, ever. Aftermath of rBa84f1c02d251.
2021-10-26Cleanup: LibQuery: Rename `BKE_LIB_FOREACHID_PROCESS` to ↵Bastien Montagne
`BKE_LIB_FOREACHID_PROCESS_IDSUPER`. More in-line name with the rest of that macro-based API, especially since this will be extended in the future.
2021-09-16Fix: properly implement the 'only append' execption case for WorkSpaces.Bastien Montagne
Add needed extra flag and utils to IDType to mark and check an ID type as only appendable. Note that this is only a loose user-level enforcement currently, in any case you need to be able to link an ID to append it currently, so for low-level code this does not really matter. Currently only WorkSpace and Screen ID types are marked with the new `IDTYPE_FLAGS_ONLY_APPEND` flag.
2021-09-15Fix broken WorkSpace use after recent refactor of append code.Bastien Montagne
Essentially, Workspace (and Screen) types were defined as not localizable. In previous code it happended to work by mere chance (code path taken in `BKE_library_make_local` was conviniently skipping the call to `BKE_lib_id_make_local` in that case, hence not checking for `IDTYPE_FLAGS_NO_MAKELOCAL` flag of the localized ID type). This is a total abuse of this IDType flag, for now removing it. That specific case (IDtype appendable but nor linkable) requires its own proper flag, this will be tackled in a later commit. Issue introduced in rB3be5ce4aad5e.
2021-08-06Cleanup: rename `FileList::asset_library` → `asset_library_ref`Sybren A. Stüvel
In the `FileList` struct, rename the `AssetLibraryReference *asset_library` field to `asset_library_ref` -- it's a description of which asset library is used, and not the asset library itself. This is to make space for a future `AssetLibrary *asset_library` field, which will point to an actual asset library struct/class. No functional changes.

2021-07-21Assets: Rename workspace active asset library DNA variableJulian Eisel
This new variable was introduced with 7898089de3f2. We don't usually use an `active` prefix variable. Plus, this makes the name match the one of the Asset Browser active library variable, so we can use the `rna_def_asset_library_reference_common()` helper for both. This will cause Asset Views to open with the default "Current File" Asset Library. We could avoid that, but it's a minor issue really.
2021-07-15Assets: Add an active asset library per workspace, for the UI to useJulian Eisel
This per-workspace active asset library will be used by the asset views later. Note that Asset Browsers have their own active asset library, overriding the one from the workspace. As part of this the `FileSelectAssetLibraryUID` type gets replaced by `AssetLibraryReference` which is on the asset level now, not the File/Asset Browser level. But some more work is needed to complete that, which is better done in a separate commit. This also moves the asset library from/to enum-value logic from RNA to the editor asset level, which will later be used by the asset view.

2021-02-25Refactor: IDTypeInfo: Add `owner_get` to get owner of embedded IDs.Bastien Montagne
This concerns currently only collections (`master_collection` of scenes) and root node trees. It removes the matching type-specific helpers (`BKE_collection_master_scene_search` and `BKE_node_tree_find_owner_ID`). No functional change expected here. NOTE: Current implementation of `owner_get` is far from optimal, we could probably do it better, see {T69169}. NOTE: While it could also have it, shapekeys IDTypeInfo was left out of this change for now. Mainly because it sould not be used currently, and we ultimately want to demote shape keys from ID status anyway.
2021-01-22LibOverride: Add an 'post apply' callback to IDTypeInfo.Bastien Montagne
Currently this is needed to properly tag PointCache's for info update (fixes an issue reported in T82503). Suspect we may need this in more cases in the future though, RNA assign/update processes are not always 100% enough to deal with complicated corner cases.
2020-11-03Add a callback to `IDTypeInfo` to allow preservation of some data accross ↵Bastien Montagne
memfile undos This is essentially adding that new callback, and using it only for already existing Scene's 3DCursor. Note that the place where this is called has been moved again, after all have been lib-linked, such that those callbacks may also work on ID pointers.

2020-10-08Cleanup/refactor: `BKE_libblock_alloc` -> `BKE_id_new` in ID creation code.Bastien Montagne
Better use higher-level code from common ID management when possible. Helps to de-duplicate logic, and reduces outside usages of more 'dangerous' functions. Note that we could get rid of many of those `BKE_<id_type>_add` functions now, but on the other hand several of those take extra parameters and perform additional actions, so think we can keep them all for now as 'non-standard ID specific creation functions'.

2020-10-02Fix (unreported) design flow in how workspace's relation data are read from ↵Bastien Montagne
.blend file. Relying on pointer addresses across different data-blocks is extremely not recommended (and should be strictly forbidden ideally), in particular in direct_link step of blend file reading. - It assumes a specific order in reading of data, which is not ensured in future, and is in any case a very bad, non explicit, hidden dependency on behaviors of other parts of the codebase. - It is intrinsically unsafe (as in, it makes writing bad code and making mistakes easy, see e.g. fix in rB84b3f6e049b35f9). - It makes advanced handling of data-blocks harder (thinking about partial undo code e.g., even though in this specific case it was not an issue as we do not re-read neither windowmanagers nor worspaces during undo). New code uses windows' `winid` instead as 'anchor' to find again proper workspace hook in windows at read time. As a bonus, it will also cleanup the list of relations from any invalid ones (afaict it was never done previously). Differential Revision: https://developer.blender.org/D9073
2020-09-29Fix unreported Eisenbug leading to a crash when reading a blend file.Bastien Montagne
This took more than a day to fully investigate and understand, one of the reasons being that the probability of the issue to show up was extremely low, and subjected to very specific random factors. Root of the issue is that, in some very rare cases, a newly read ID might get the exact same memory address as the one it had when the blend file was saved. In that case, `BKE_workspace_active_set` would return immediately, since the pointer to the active workspace would remain unchanged. But that lead to having an unset NULL active layout pointer, which would crash when attempting to get e.g. the active screen. For the record, I ran into this when running a specific build (master with one flag added to the `LIB_ID_CREATE` ones, with value `1 << 3`), using a specific set of options (`--background --factory-startup -noaudio`), and passing the .blend file from T80090 as argument.
2020-08-28IDTypeInfo: add .blend file io callbacksJacques Lucke
This is part of T76372. It adds the `blend_write`, `blend_read_data`, `blend_read_lib` and `blend_read_expand` which correspond to the various steps when reading and writing .blend files. Having these callbacks allows us to decentralize the blenloader code a lot more. This has the affect that code related to any specific ID type is less scattered.

2020-08-07Cleanup: Blenkernel, Clang-Tidy else-after-return fixesSybren A. Stüvel
This addresses warnings from Clang-Tidy's `readability-else-after-return` rule in the `source/blender/blenkernel` module. No functional changes.
2020-05-26Cleanup/refactor: Workspace API, boilerplate code, early exitJulian Eisel
* Simplify workspace API a bit * Comment on behavior of workspace-layout relations where exposed in API * Remove annoying getters/setters * Avoid lookups if we can early exit * A NULL check is removed in `direct_link_workspace()` that I don't see a need for. Am not 100% sure though, fingers crossed. In general these changes should improve readability and make things easier to reason about.

2020-02-18Fix (unreported) wrong handling of usercount in `BKE_workspace_add()`.Bastien Montagne
This does not seem to be an actual issue in current master code (as creating a new ID will assign 1 user to it by default), but is breaking generic usercount handling in future changes.
2020-02-10Cleanup/refactor: Rename `BKE_library` files to `BKE_lib`.Bastien Montagne
Note that `BKE_library.h`/`library.c` were renamed to `BKE_lib_id.h`/`lib_id.c` to avoid having a too generic name here. Part of T72604.
2020-01-15Fix T70965: Undo crash with specific fileJulian Eisel
Not sure how the WorkSpaceLayout.screen pointer could end up being NULL, but apparently that happens, or at least happened with older files. Rather than just adding NULL-checks, prefer not keeping around those invalid layouts at all.
2019-11-29Tests: prevent failing assertion when running blendfile-loading testSybren A. Stüvel
Loading a blendfile allocates one or more windows that need to be freed. Freeing those windows also calls `BKE_workspace_instance_hook_free()` to free workspaces. However, in the `BlendfileLoadingBaseTest` test there are no workspaces allocated. This caused an assertion failure, which was worked around by not asserting when Blender is running in background mode. Reviewed by @Severin via pair programming

2019-03-08Cleanup: use plural names for Main listsCampbell Barton
Convention was not to but after discussion on 918941483f7e we agree its best to change the convention. Names now mostly follow RNA. Some exceptions: - Use 'nodetrees' instead of 'nodegroups' since the struct is called NodeTree. - Use 'gpencils' instead of 'grease_pencil' since 'gpencil' is a common abbreviation in the C code. Other exceptions: - Leave 'wm' as it's a list of one. - Leave 'ipo' as is for versioning.
