This function never succeeded as an off by one error checking the last
character always indexed the null byte.
The 'for' loop was broken as of [0] since the unsigned number could wrap
around with some RNA paths causing out of bounds memory access.
This is an example where tests would have caught the problem early on,
RNA path tests are planned as part of D15558.

We only need to 'manually' remap RNA ID pointer property to the newly
created override if the owner itself was not already a local override.
Also some more minor tweaks to notifiers sent when creating the
override.
|
|
|
|
Assigning to RNA ID pointer properties will not _always_ trigger a
rebuild of the outliner tree, so try to enforce this when actually
creating overrides.

This introduces a new `UI_MT_button_context_menu` class which is
registered at startup. Addons can append/prepend draw functions to this
class, in order to add their custom context menu entries.
The new class replaces the old `WM_MT_button_context` class, thus
requiring a small change in addons using this feature. This is done
because addons were previously required to register the class
themselves, which caused addons to override each other's context menu
entries.
Now the class registration is handled by Blender, and addons need only
append their draw functions. The new class name ensures that addons
using the old method don't override menu entries made using the new
class.
Menu entries added with the legacy `WM_MT_button_context` class are
still drawn for backwards compatibility, but this class must not be used
going forward, as any addon using it still runs the risk of having its
menu entries overridden, and support for the legacy class is subject to
removal in a future version.

Case where object was directly linked and not owned by a linked
collection was not properly handled, added some level of support for it
now.
Note that the behavior may not always be ideal in cases where the linked
object would be linked in many different local collecitons, hard to get
best solution always from this Editor given limited hierarchy data
available here.
|
|
Could lead to crahses in some cases, with outliner drawing code
accessing freed ID data in its tree.
|
|
This behavior is now implicitely controlled by the 'Make' operations,
based either on context or selected items.
|
|
The object data path item wasn't added properly.
Also remove some of the unnecessary variables and forward declarations.

handle_subversion_warning() was reporting with RPT_ERROR type, replaced
with RPT_WARNING.
RPT_ERROR would stop python scripts opening files written by newer
Blender binary with bpy.ops.wm.open_mainfile(), preventing further code
from running. This does not seem right since Blender itself still loads
the files.
Ran into this checking T100446 in 2.93.

Pressing escape when rendering a viewport animation would
access the freed even and crash (with ASAN enabled).
Always check the context's window before the event as this is a signal
a file was loaded or the window was closed (and it's events freed).

Constant_rate_factor mode was not updated when choosing DNxHD codec in
RNA update function.
Ensure `FFM_CRF_NONE` is set.

Loopback ID pointers should be ignored here as well, otherwise they are
very efficient at preventing proper detection of 'leaf' override IDs in
a hierarchy.

This fixes missing selection updates in UV editor, both with GPU subdivision
and with the Modified Edges display option for modifiers in general.
It also fixes the UV editor incorrectly showing the cage mesh with deformed
coordinates. These are not yet supported by the UV selection system.
Changes:
* Always read selection state from the editmesh when building batches. The
flags in the evaluated mesh can be outdated as selection bypasses depsgraph
evaluation for performance, and instead may just clear the batches.
* runtime.is_original is only valid for the bmesh wrapper. The check for
building the UV cage should only use that if the mesh is a bmesh wrapper.
* Don't create cage batches for objects whose mesh is in edit mode, but that
are not themselves in edit mode, there is no need.

Move override creation into their own menu, add entries for reset and
clear operations.

create override
Add support for the (geometry)node tree case.
Also add warning about not being implemented for other types.
|
|
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.

Only object renaming was properly depsgraph-tagged, now all IDs (and
their sub-data like bones etc.) should be properly handled.

While fixing T100302 (rBd76583cb4a1) I did not realize that the
change in imported vertex order would actually matter. Turns out, it
does for morph targets / mesh shape keys. So redo the fix in a way
that does not change the vertex order. Fixes T100421.

Materials can be changed by other evaluations like geometry nodes,
now handles that kind of situation.

Node tagging needed to happen after the undo node's null check.

When dropping file to sequencer timeline, coordinates for strip position
and overlap handling are used even if not set.
Reset internal state in on_drag_start callback and set is_modal
variable only if coordinates are updated. This way when dragging file
from external file browser, strip is added at current frame as before
modal operator was implemented.

Ensure render passes are allocated in the result prior to writing them.
Alternative could be to not write empty passes, but that is kind of
different from perspective of s one who reads the file.

The status bar keymap items still don't get translated because the
TIP_ translation introduced by rBe1974ae30e46 uses the wrong context:
it uses the default context, while the extraction introduced in
rB630b961f234e uses ID_WINDOWMANAGER.

This is not dynamic: it only happens when the dir is added to the
list--automatically for recent files, and by the user for bookmarks.
Entries can then be manually renamed like other dirs. They will
keep the same name if the language is changed afterwards.

In this case the array allocation would allocate an array of size zero.
This would then later lead to out of bounds memory reads.
Now the code will skip zero length allocations.

As the surface normal is calculated along with the coordinates, the
surface depth was always being used when surface orientation was set.
Therefore, even calculated, ignore the surface depth when it is not
required.
Also promote an optimization when neither orientation nor depth is required.

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.

In complex scenes featuring thousands of connections between IDs in
their liboverride hierarchies (e.g. Heist files), the time required to
check if tree items were available (before allocated a new one) would
become insanely long (O(n^2)).
This commit brings it back to roughly a constant time, only re-checking
the whole array for unused items once in a while (once every 10k times
currently), since in almost all cases is the index after `lastused`
value is not unused, and you have reached the end of the currently used
array of items, you actually need to 'allocate' a new one anyway.
It also improves the handling of `lastused` index, in particular in
`tse_group_add_element`.
This makes switching to the Outliner override hierarchy view in Heist
scenes from virtually infinite time (more than 30mins for sure) to about
20 seconds on my machine. Still far from being effectively usable.
Note that this is only a bandaid fix anyway, root of the issue is that
this view has to deal with way too many items in its tree, current code
is not designed for that. Either outliner has to improve its tree
handling (by only building subsets of the whole tree maybe?), or we have
to cull/filter out some of the ID relationships between overridden IDs
to make this view actually usable. Maybe limit the depth of the tree?

Fix wrong assumption that 'embedded' IDs are only ever used by their
owners. This is especially not true with shape keys.
Also small optimization by adding an eraly abort when both IDs are the
same (i.e. an ID has a pointer to itself).
|
|
In some cases, there is a chance code already knows who might be the
owner of the given ID, in which case it can be more efficient to check
it first (especially in cases like embedded node trees or scene
collections, where the only other way is to loop over all possible
owners currently).
Will be used in next commit in some Outliner fix.

The use of `float` for intermediate intersection record led to some

GPU_exit is now expected to run within an active GPU context.
Also run BLF_exit and IMB_exit first they can use GPU resources and gave

Report T98781 and part of T97642: the MTLMaterial info only captures
image nodes and the default socket values. When the image information
is present, do not emit the socket defaults - the .MTL spec states
they are multiplied together, but the default value is not used
in blender when the socket is connected.
Also contains svn tests repository update to extend the test coverage,
and update test expectation outputs.

When RMB select activated the selection tool, Alt-RMB would both
tweak and loop-select.
Fix/workaround this by passing though 'enumerate' unless the option

While T77801 itself is working as expected in the new C++ obj
importer, the repro file there uses absolute paths to material images,
yet the images themselves are right there in the current folder.
The old python based importer did find them, since it was doing a
really complex image search. My understanding is that while C++
importer was developed, it was decided to not do that -- however
just the "basename file in the mtl directory" sounds simple enough
and gets the repro case file work correctly.

There is no need for these to be limited to -10..10, soft limits are enough.
