One thing to keep in mind is that while `ob->actcol` is one-based (if
materials are assigned), `active_material_index` is zero-based so we
have a couple of places to make sure whenever materials are assigned,
we should always be in the range of `1..totcol` for `ob->actcol`.
In the particular case of the report, the last remaining material slot
was removed (`ob->actcol` gets rightfully zero then), but assigning a
material from the `template_ID` then calls `BKE_object_material_assign`
with zero as the active index.
The internal `act` number was corrected [ `std::max<int>(act, 1)` ],
but did not end up in `ob->actcol`.
`BKE_object_material_resize` [which all code assigning/removing/...
materials eventually comes down to] used to do the "sanitizing" actually
(but exited early when `totcol` didn't actually change).
There were other places to, clamping to a proper upper or lower bound.
So to resolve, move the code for sanitizing into its own function and
use it after `BKE_object_material_resize` (and from a couple of places).

Move the existing USDZ export test from C++ to Python for better
validation. The resulting file is now run through the `usdchecker`
system and we also check the contents of the resulting archive for the
expected texture file. This helped uncover a pathing issue in the
resulting archive where the 'textures' directory was misnamed on win32;
though it was still functional.

Depend only on `getcwd` and `chdir` rather than attempting to also
consider the `PWD` environment variable.
There's situations where these differ, and most easily seen when running
the Python tests. Calling `pathlib.Path.cwd()` will return something
like `/home/blender/git/blender-vexp/build_asserts/tests/python` while
PWD is `/home/blender/git/blender-vexp/build_asserts`. In this case,
calling `getcwd` will match what Python shows.
Additionally, this now matches what Windows and Mac do for these
affected APIs.

* GHOST is an implementation detail, Blender environment variables should
have the BLENDER_ prefix.
* Don't put links in command line help output. We don't do this for other
arguments either, and it's trivial to search for this online.
* Make description more straightforward and line wrap.
* Use CLOG for logging.

- Make PTCACHE_COMPRESS_ an actual enum
- Clarify that while it looks like bitmask, it really is just an enum
- Make ptcache_file_compressed_write take similar arguments as
ptcache_file_write (item count and item size)
- All callers of ptcache_file_compressed_write were doing compressed
result memory allocation in exactly the same way; just make it happen
inside the function itself. This also makes it no longer need
the callers to do "is this zstd?" check around the call.
- The lzma "props" buffer was dynamically allocated for no good reason,
just make it a simple array, and clarify the variable names.
- Remove BLI_assert_unreachable() from ptcache_file_compressed_read;
asserts are for "impossible" situations; this one just happens any
time one opens a 4.x file with caches in 5.0.

Looks like this was caused by 3de916ca25.
Steps to reproduce were:
- Switch to the Scripting workspace
- Paste:
`C.screen.areas[5].spaces[0].rna_type.properties['show_region_asset_shelf'].`
- Press tab
The RNA property getter should always return a value, even when empty.
That's what other such getters do as well.
The File Output node does now allow empty names for its sockets, so
doing things like flat RGBA pass in an unnamed layer is impossible,
which was possible before the recent redesign of the node. To allow
this, socket items accessors now have an option to allow empty names.
Implementation wise, the non-default variant of BLI_uniquename_cb was
used to make the empty name replacement optional. Incidentally, the new
function is more CPP friendly, so the MAX_NAME length limitation was
lifted.

The code path isn't well defined when there aren't any faces, causing
the vert, face, and corner normal caches to call each other, potentially
trying to lock the same mutex twice.
Duplicating a strip that references an ID like the scene strip would not
duplicate the scene. This is wanted in some workflows.
To align with the rest of Blender, this changes the behavior for how
strips are duplicated:
* `Shift + D` ("duplicate"): Duplicate the strip and also duplicate the
IDs referenced by the strip. Currently this only affects `Scene`,
`MovieClip`, and `Mask` strips.
* `Alt + D` ("duplicate linked"): Duplicate the strip, but reference the
same IDs. This is the current behavior in `main`.
Part of #144063.

This is similar to #144199. It needs a few more changes because more places
handle geometries in a special way compared to data-block sockets.
It might be that there are more usages of `GeometrySet` as value for geometry
sockets instead of `SocketValueVariant`. Unfortunately, there isn't really an
automated way to find these. So far I found all the places that needed fixing
through tests.
This is the last socket type that did not use `SocketValueVariant` yet. So
afterwards, it's likely possible to simplify a bunch of code to use
`SocketValueVariant` instead of `void *`.

During a short period (Blender 500 sub 33) the legacy custom data
struct was saved in an invalid state. This adds a check to
avoid crashing when loading a file that was saved during that time.

This PR proposes to add an environment variable for forcing vsync to
be on or off. My primary use case was to disable vsync for forcing
viewport rendering performance tests not to be capped at the display
refresh rate when #142984 is used for removing animation frame rate
limits.
I initially added the environment variable "GHOST_VSYNC_OFF", but
found "GHOST_VSYNC=0/1" to be more easily understandable.
Usage:
- GHOST_VSYNC=0 => Vsync is forced off
- GHOST_VSYNC=1 => Vsync is forced on

This was only affecting the shadow pass because it is the
only one to use multiview.
The `drw_ResourceID_iface.resource_index` was incorrectly
set up in the vertex shader to the already shifted index,
resulting in double shift which resulted in resource index
being 0 in fragment shader.

When using the resize dyntopo operator the overlay helping to choose

The remapping from old to new linked IDs was done one by one, with all
the related pre/post processing. In particular for objects, this could
easily lead to quadratic cost (need to loop over all objects for each
object)...
Solved by reworking the remapping logic in relocation code to process
all linked data in a single call.
From quick tests locally, it makes relocating a library with 10k object
got from 50s to about 5s.
A 40k linked objects case goes from 'way too long to measure' to about 4
minutes.
So there is likely still some things that could be improved here
(processing time still does not seem to be O(n)), but at least it's
usable now.

The previous code to get unique instance ids did not actually ensure 100%
uniqueness. Now the code does and hence the "almost" from the name is removed.
In practice, this change likely does not have any impact because the fallback
case is very unlikely to be reached.

The fix is to detect when the compute context is recursive and to stop the
search early in that case. Currently, this does not generate a warning. There
will be a warning when trying to evaluate the recursive closure though.

Use `SocketValueVariant` for all the data-block types as well. Before it was
used for e.g. float, integer and menu sockets.
The only remaining type afterwards is the geometry socket which will be moved
separately.
Using `SocketValueVariant` for all socket types will simplify code later on and
also removes the need for dealing with raw memory in more cases.

I'm not sure why the edge domain was handled differently than the other
domains with regards to attributes on unexpected domains. Now use a
simpler more consistent solution that removes invalid selection
attributes before they're used at all.
Broken with new 4.5 cache implementation; the loop for building
image sequence proxies was not flushing the intra-frame cache
between frame changes. This affects image proxies since they go
through the whole VSE render stack; does not affect video proxies
since they just manually decode the file frames.

Toolbar. And for headers.

The change changes the way the converted curves are evaluated.
It may be better and a valid choice, but it needs to be considered
more carefully since it would be a breaking change.
