In very specific cases, during intersection testing, `intersect` can
add polygons already checked as duplicates in the buffer that
corresponds to the rest of polygons that can form groups of duplicates.
As the buffer cannot have repeated indices, re-adding, even
temporarily, these duplicates can cause a buffer overflow.
While this may have some impact on performance, it's difficult to
predict these cases and thus add a buffer pad.
So the solution is to check if they are already duplicated.
This patch enables edge panning for the operators where there was
a mismatch in behaviour between using the shortcut `G` and the
"Move" operator exposed via the menu and operator search.
Commit 19da434e9c introduced a `view2d_edge_pan` property which
was activated for the translate operators invoked when pressing G in
the default keymap.
The property is not enabled by default, to avoid it getting in the
way in some cases, so the "Move" operators exposed via the menus
didn't have edge panning. This lead to inconsistent behavior between
moving via the shortcut or via the menu.

The use of wordexp(3) permits arbitrary code execution from manually-crafted
glTF files. See https://github.com/syoyo/tinygltf/issues/368 for more details.
In practice this shouldn't be an issue for Blender since the GlTF data isn't
manually crafted but from the OpenXR runtime (a bit like a driver). But
updating the library to include the fix is not a big deal anyway.
Note that the warning that required the local modification is no longer present upstream since

Workaround for a crash when `addComputePipelineFunctionsWithDescriptor` is called *after* `newComputePipelineStateWithDescriptor` with linked functions (i.e. with MetalRT enabled). Ideally we would like to call `newComputePipelineStateWithDescriptor` (async) first so we can bail out if needed, but we can stop the crash by flipping the order when there are linked functions. However when addComputePipelineFunctionsWithDescriptor is called first it will block while it builds the pipeline, offering no way of bailing out.
Note that this only has an impact when the "MetalRT (Experimental)" option is checked.

Archlinux faced an issue with AoT compilation: https://bugs.archlinux.org/task/77554
These were due to compiler flag strings handling going wrong when cmake
calls the custom command. It ended up moving quotes around, leading flags to
get passed to the main compiler instead of the graphics compiler and trigger
the following error: "Unrecognized build options: -ze-opt-regular-grf-kernel".

The count wasn't clamped above zero in some newly optimized code.
Instead of adding it there, move the clamping to the field network,
similar to some other nodes. That makes it so the rest of the code
doesn't have to deal with the clamping, and should be faster in the
single-value case.
When subsampling was introduced in VSE it was disabled during
editing. Only when rendering it was enabled. This lead to
cache being different between editing and rendering. Leading
to confusion.
This PR will enabled the subsampling when editing. This way
it is more consistent.

Some checks here are really critical and should assert, but that one is
more an indication that something is not going right, though data itself
should still be mostly valid, so better warn the user with a LOG
warning, than be silent in release builds, and crash in debug ones.
The traversable handle of a BLAS may be zero when the relevant geometry
is empty (no triangles/curves/points/...), as no BLAS is built in such cases.
It is not correct to attach a zero handle to a TLAS, so filter out such instances.
Invalid nodes are not added to the lazy-function graph. Therefore, their
outgoing links are also not added, which implies that the targets need
some default value.
The correction bbc6bb3468 was still wrong because there it was
disregarded that `vert_ctx_len` does not necessarily indicate merges in
the same polygon.
Therefore, it is not safe to rely on `vert_ctx_len` to count possible
new polygons.
NOTE: It might be worth preempting part of the
`weld_poly_split_recursive` logic to identify what the new polygons are
in advance. But this can be left for a future refactor.
Node tree updates can crash if the tree contains a node group that points at an "undefined" tree type.
This can happen if the tree is linked from a library and the path is lost,
or if a custom (python) tree is used and the script is not run.
The fix is to check if the node group type is valid ("registered") and return an empty list otherwise.

With the move to Gitea the URI for line numbers changed from `$1234` to `#L1234`.
The change also removes a superfluous space character from the generated RST syntax.
When trying to use the Fill Range by Selection operator, in the
Distance from Camera Freestyle modifier, the operator fails if no
camera is active in the scene.
Before getting the data from the camera, check that it is defined, and
return otherwise.

Pick select is only meant to change a single element from a single
data-block. However, the operator worked on each object individually
rather than first finding the closest point, then processing the
selection. Change the operator to find the closest point across all
objects, then deselect if necessary, then select the closest point.

When running unit tests or other fast completing renders, forced crashes can occur if there are any slow, outstanding PSO compilation requests (due to the `std::terminate` fall-back case in `~ShaderCache`).
This patch eliminates the need for this shutdown hack by using of the async version of `newComputePipelineStateWithDescriptor` when creating a PSO for the first time. In doing so, we are able to explicitly respond to app shutdown instead of waiting for the pipeline to finish compiling (..and then timing out and force-crashing). We still use the blocking version of `newComputePipelineStateWithDescriptor` when loading from an archive, as this can handle loading from a corrupted archive gracefully. Finally, we move `addComputePipelineFunctionsWithDescriptor` to *after* the PSO is built (as this will trigger a full blocking compile if the PSO has not yet been built, which would bring back the original issue).

After ed870f87b9, panels headers displayed inside panels had their
label duplicated when translations were enabled. This is because a
string comparison was made against the original message, instead of
the translated message.
Pull Request: https://projects.blender.org/blender/blender/pulls/105151
- "Lines" in the sense of number of lines
- "Number" can mean "amount, count" or "index, offset"
- "Second" can be an ordinal number or a unit
- "Root": add the brush curve to the "square root falloff" sense
- "Strip" can be a sequence or a type of hair rendering
- "Constant" in the sense of a value, for the Geometry Nodes add
submenu (#105447).
Additionally, extract:
- "Press a key" from the Keymap preferences.
- "MaskLayer", upon new mask layer creation
Ref #43295, #105447
This was caused by an incorrect assumption in the solver:
It tries to solve both collision and length constraints simultaneously,
using the projected movement of a point as a slide direction along the surface.
This only works if the distance of the previous curve point to the surface
is less than the allowed segment length. Otherwise the segment will
exceed the allowed length even with zero slide and NaN values are computed.
The case of larger surface distance can occur if the previous segment
solve was already stretching the current segment and then the point
moves further away. In this case we can simply clamp the segment length
without violating the contact constraint.

Some UI functions have a "translate" argument, which if set to False
specifies that the message is not to be translated. This sometimes
means that it was already translated beforehands.
But many messages were still getting extracted, sometimes twice in
different contexts. Some featured errors because the arguments of
various functions would be concatenated, such as:
```
col.label(text=iface_("Branch: %s") % bpy.app.build_branch.decode('utf-8', 'replace'), translate=False)
```
which would get extracted as:
```
msgid "Branch: %sutf-8replace"
```

3e5ce23c99 introduced a regression in case the freed Main was part of a
list, and was supposed to be removed from it, since calling
`BLI_remlink` does _not_ clear the `prev`/`next` pointers of the removed
link.
This commit also contains a few more tweaks to recent related b3f42d8e98
commit.
Pull Request #105485
While this behavior can be useful in some cases, it can also create
issues (as in one of own recent commits, 3e5ce23c99), since it
implicetly keeps the removed linknode 'linked' to the listbase.
At least warn about it in the documentation of `BLI_remlink`.
This commit introduces a new Main boolean flag that marks is as invalid.
Higher-level file reading code does checks on this flag to abort reading
process if needed.
This is an implementation of the #105083 design task.
Given the extense of the change, I do not think this should be
considered for 3.5 and previous LTS releases.
This has the effect that the message is cut off at the end of the
first line. I copied the solution from other similar docstrings
elsewhere in the code.
As far as my regex-fu can tell, there are no other occurrences of this
in the codebase.
Issue reported by Joan Pujolar in #43295.

If the texture image path in the MTL is a "quoted" absolute path, the importer will fail to find the

in all cases.

msgfmt has a TBB dependency though bf_blenlib, now for a release build
The MSVC linker is smart enough to realize none of the TBB code is
actually used and discards it. In debug mode the linker is a bit more
conservative and doesn't, leaving msgfmt with a runtime dependency
on TBB. The problem here is, we only copy the runtime dlls during
the install phase, and msgfmt runs long long before that.
For this reason when we run msgfmt we should make sure any runtime
needs it could have are met in the path, there already is a handy
variable for that since oslc has similar requirements.
