In `Orphan Data` (or `Blender File`) view, the ID pointer of the
actions's parent tree-element wasn't actually pointing to an ID, but to
the list-base containing the IDs.
Early out (with a warning) if the object or object-data to unlink the
action from is not clear.

The main problem is that the node tree was not properly updated
after a property in the tree changed. More specifically, the collection
pointer in the Collection Info node was cleared, but the node tree
was not updated after that (usually this is handled by rna updates).

This is the conventional way of dealing with unused arguments in C++,
since it works on all compilers.
Regex find and replace: `UNUSED\((\w+)\)` -> `/*$1*/`
When a change happens which invalidates view layers the syncing will be postponed until the first usage.
This will improve importing or adding many objects in a single operation/script.
`BKE_view_layer_need_resync_tag` is used to tag the view layer to be out of sync. Before accessing
`BKE_view_layer_active_base_get`, `BKE_view_layer_active_object_get`, `BKE_view_layer_active_collection`
or `BKE_view_layer_object_bases` the caller should call `BKE_view_layer_synced_ensure`.
Having two functions ensures that partial syncing could be added as smaller patches in the future. Tagging a
view layer out of sync could be replaced with a partial sync. Eventually the number of full resyncs could be
reduced. After all tagging has been replaced with partial syncs the ensure_sync could be phased out.
This patch has been added to discuss the details and consequences of the current approach. For clarity
the call to BKE_view_layer_ensure_sync is placed close to the getters.
In the future this could be placed in more strategical places to reduce the number of calls or improve
performance. Finding those strategical places isn't that clear. When multiple operations are grouped
in a single script you might want to always check for resync.
Some areas found that can be improved. This list isn't complete.
These areas aren't addressed by this patch as these changes would be hard to detect to the reviewer.
The idea is to add changes to these areas as a separate patch. It might be that the initial commit would reduce
performance compared to master, but will be fixed by the additional patches.
**Object duplication**
During object duplication the syncing is temporarily disabled. With this patch this isn't useful as when disabled
the view_layer is accessed to locate bases. This can be improved by first locating the source bases, then duplicate
and sync and locate the new bases. Will be solved in a separate patch for clarity reasons ({D15886}).
**Object add**
`BKE_object_add` not only adds a new object, but also selects and activates the new base. This requires the
view_layer to be resynced. Some callers reverse the selection and activation (See `get_new_constraint_target`).
We should make the selection and activation optional. This would make it possible to add multiple objects
without having to resync per object.
**Postpone Activate Base**
Setting the basact is done in many locations. They follow a rule as after an action find the base and set
the basact. Finding the base could require a resync. The idea is to store in the view_layer the object which
base will be set in the basact during the next sync, reducing the times resyncing needs to happen.

The context menu would always show a section with "Select", "Deselect",
"Hide", "Unhide" and "Select Linked" if there were no more specific
operators to show (e.g. modifier operations). For many tree elements
they did not make sense and simply would do nothing. Only show the
section for supported types.
- Remove unnecessary calls to `get_element_operation_type()` (result
wasn't used).
- Remove branches/checks for cases that couldn't possibly happen.
(assert instead).
- Ensure all return arguments are set so caller can't make the mistake
of forgetting that.
- Early exit instead of big `if` block.
- Use `const`.
These functions used the term "find", which makes it sound like a lookup
callback, when in fact it would add elements to a set for further
processing. So use "collect" instead.
With C++ we should transition towards namespaces to avoid naming
collisions. Having the namespace in place is the first step for that
transition.
Plus, the `typedef` isn't necessary for struct/class/enum definitions
in C++, so avoid the verbosity it adds.
Inconsistencies in update/tagging code between different code doing the
same 'Clear. liboverride operation lead to crashes in some cases.
Unify deg tagging and WM notifiers accross the three editor-level
codepaths performing the common Make/Reset/Clear operations.
Preserve if possible the active object accross Clear operation.
Several cleanup/rename/re-arangement of code to make it more consistent.
Also add new outliner liboverride operators mapping to the manual,
though this is useless currently as this feature is not working in many
part of the UI, including the Outliner contextual menu.
Follow-up to design discussions here at the studio, add liboverride
operations into their own sub-menu, with three main entries:
- Create: Create, or enable for user editing, override hierarchies.
- Reset: Keep overrides data, but reset all local changes to the
reference linked data values.
- Clear: like reset, but also turn editable overrides back to system
overrides (aka non user editable).
Those three options can all operate either on the selected items, their
content only, or both.
Advanced operations are moved into a "Troubleshoot Hierarchy" sub-menu,
where one can resync, resync enforced, and fully delete library
overrides. Those operations always affect a whole override hierarchy,
regardless of which items are selected or not.
This commit allows to select several data-blocks in the outliner and
create overrides from all of them, not only the active one.
It properly creates a single hierarchy when several IDs from a same
hierarchy root data are selected.

The outliner would tagg all existing local IDs (for remap from linked
reference data to newly created overrides) when creating a new override.
This would become critical issue in case there is several existing
copies of the same override hierarchy (leading to several hierarchies
using the same override).
Further more, BKE override creation code would not systematically
properly remapp linked usages to new overrides one whithin the affected
override hierarchy, leading to potential undesired remaining usages of
linked data.
This is temporary to investigate which behavior should be kept when
creating an override hierarchy if there are no cherry-picked data
defined: make all overrides user-editable, or not.
This removes the 'make override - fully editable' menu entries.
Usual same issue with outliner operations, where you apply it on one
item, and then try to apply it again on same item listed somewhere else
in the tree...
Fixed by using the 'multi-tagged deletion' code we now have for IDs,
that way tree-walking function just tags IDs for deletion, and they all
get deleted at once at the end.
The callback would just assume that it's only called on materials, which
may in fact not be the case. It could also be called for other ID types
and layer collections (see `outliner_do_libdata_operation()`). Properly
check this now.
Also avoid faling silently when the object or object-data to unlink from
couldn't be determined. Report this to the user. Operators that just do
nothing are confusing.
This issue was only exposed by ba49345705. The ID pointer of the
material's parent tree-element wasn't actually pointing to an ID, but to
the list-base containing the IDs. It was just unlikely to cause issues
in practice, although an assert was thrown.
Just don't do anything if the object or object-data to unlink the
material from could not be found. The following commit will introduce a
error message about this.
Some operators OR'ed the existing flags in a way that made it seem
the value might already have some values set.
Replace this with assignment as no flags are set and the convention
with almost all operators is to write the value directly.
Add the following macros for enums as support for these features wasn't
all that obvious and there were some inconsistencies in their use.
- RNA_ENUM_ITEM_HEADING(name, description)
- RNA_ENUM_ITEM_SEPR
- RNA_ENUM_ITEM_SEPR_COLUMN
(Not meant to cause user visible changes.)
Makes use of the new iterators introduced in the previous commit. Some
benefits:
- Shorter, simpler, easier to read & understand
- Deduplicates logic
- Centralizes iteration logic, making it easier to replace tree storage
(as planned), see previous commit.
- Avoids having to pass (sub-)tree to iterate around (often redundant
since it's just `SpaceOutliner.tree`, even though `SpaceOutliner` is
already passed).
- Function arguments that are only passed to the recursive call are
recognized as unused (found and removed a few).
Also does some general cleanups while refactoring the code for the
iterators. Use `const`, use references (signals null is not expected),
early-exit (see 16fd5fa656), remove redundant arguments, etc.
Avoids having to manually enable data-blocks for user-edition when you
do not care about what should be edited by whom. Similar to default
behavior before introduction of system overrides (aka non-user-editable
overrides).
This reverts commit 30534deced.
After discussion and feedback from users, it's better to keep this tool
available until there is time to properly re-think the whole Outliner's
contextual menu.
This feature is very advanced, and the way it was exposed in the
Outliner was very confusing at best.
It remains available through the Python API (`ID.user_remap`) e.g.
This was historically the only way to change/fix paths of library files
in Blender. However, only changing the path then required a manual
reload of the library, which could be skipped by user, or a save/reload
of the working .blend file, which could lead to corruption of advanced
library usages like overrides.
Prefferred, modern way to change path of a library is to use the
Relocate operation instead. Direct path modification remains possible
through RNA (python console or the Data API view in the Outliner.
Animation would still play in the viewport.
There are two ways to unlink an action from the Outliner:
[1] `Unlink Action` on the Animation Data context menu.
This does `outliner_do_data_operation` / `unlinkact_animdata_fn` and has
the correct DEG update.
[2] `Unlink` on the Action context menu
This does `outliner_do_libdata_operation` / `unlink_action_fn` and was
missing the DEG update.
Now add the missing DEG update to the second case.
