That code is simpler and more general (not limited to some specific
values of thread numbers). It still gives similar default chunk size as
what we had before, but handles smoother increase steps, and higher
number of threads, by keeping increasing the chunk size.
No functional change expected from that commit.
This commit adds some new hashing based data structures to blenlib.
All of them use open addressing with probing currently.
Furthermore, they support small object optimization, but it is not
customizable yet. I'll add support for this when necessary.
The following main data structures are included:
**Set**
A collection of values, where every value must exist at most once.
This is similar to a Python `set`.
**SetVector**
A combination of a Set and a Vector. It supports fast search for
elements and maintains insertion order when there are no deletes.
All elements are stored in a continuous array. So they can be
iterated over using a normal `ArrayRef`.
**Map**
A set of key-value-pairs, where every key must exist at most once.
This is similar to a Python `dict`.
**StringMap**
A special map for the case when the keys are strings. This case is
fairly common and allows for some optimizations. Most importantly,
many unnecessary allocations can be avoided by storing strings in
a single buffer. Furthermore, the interface of this class uses
`StringRef` to avoid unnecessary conversions.
This commit is a continuation of rB369d5e8ad2bb7.
Many generic C++ data structures have been developed in the
functions branch. This commit merges a first chunk of them into
master. The following new data structures are included:
Array: Owns a memory buffer with a fixed size. It is different
from std::array in that the size is not part of the type.
ArrayRef: References an array owned by someone else. All elements
in the referenced array are considered to be const. This should
be the preferred parameter type for functions that take arrays
as input.
MutableArrayRef: References an array owned by someone else. The
elements in the referenced array can be changed.
IndexRange: Specifies a continuous range of integers with a start
and end index.
IntrusiveListBaseWrapper: A utility class that allows iterating
over ListBase instances where the prev and next pointer are
stored in the objects directly.
Stack: A stack implemented on top of a vector.
Vector: An array that can grow dynamically.
Allocators: Three allocator types are included that can be used
by the container types to support different use cases.
The Stack and Vector support small object optimization. So when
the amount of elements in them is below a certain threshold, no
memory allocation is performed.
Additionally, most methods have unit tests.
I'm merging this without normal code review, after I checked the
code roughly with Sergey, and after we talked about it with Brecht.
This adds per-platform change so Windows users will see file sizes calculated with a base of 1024.

Preparing for the bigger changes which will be related on passing
dependency graph to various callbacks which need it.
Differential Revision: https://developer.blender.org/D5725
Before this the timer API was relying on using a callback API to do
initialization when new file is loaded. This isn't how rest of Blender
works and it gets in a way because callbacks API is to be move to the
BKE level.
Use explicit call to timer API from where the file is loaded.
Bugs were: (1) needed an epsilon test in CCW test in order to
handle new costraint edge that intersects an existing point
but only within epsilon; (2) the "valid bmesh" output mode
sometimes left a face that included outside frame point.
Upon close inspection, the way the Offset mode works in the
Copy Rotation constraint makes no sense, and in fact, destroys
the rotation of its owner unless either it's single axis, or
the order is set specifically to `ZYX Euler`.
Since it can't simply be changed because of backward compatibility
concerns, replace the checkbox with a dropdown that provides a set
of new modes that actually make sense.
Specifically, add a mode that simply adds Euler components together,
and two options that use matrix multiplication in different order.
The Python use_offset property is replaced with compatibility stubs.

I believed the crash I experienced happened because:
1. The `extract_pos_nor_init` function is called.
2. Tasks are added to the task pool for `extract_pos_nor`.
3. The tasks begin to be executed while more tasks are added.
4. In some rare cases, all existing tasks are finished, but not all have been added yet.
5. This let the task-counter go down to zero.
6. This triggered a call to `extract_pos_nor_finish`.
7. Then more tasks are added and in the end `extract_pos_nor_finish` is called again.
A solution is to use a task pool that is suspended when created.
Unfortunately, there was an outdated comment, that was probably the root cause of the issue.

As an inherent property of matrix-based transformation math, non-
uniform scaling of a parent bone induces shear into the transform
matrix of any rotated child. Such matrices cannot be cleanly
decomposed into a combination of location/rotation/scale, which
causes issues for rigging and animation tools.
Blender bones have options to exclude rotation and/or scale from the
inherited transformation, but don't have any support for removing the
often undesired shear component. That goal requires replacing simple
parenting with a combination of multiple bones and constraints. The
same is true about the goal of inheriting some scale, but completely
avoiding shear.
This patch replaces the old Inherit Scale checkbox with a enum that
supports multiple options:
* Full: inherit all effects of scale, like with enabled Inherit Scale.
* Fix Shear: removes shear from the final inherited transformation.
The cleanup math is specifically designed to preserve the main
axis of the bone, its length and total volume, and minimally
affect roll on average. It however will not prevent reappearance
of shear due to local rotation of the child or its children.
* Average: inherit uniform scale that represents the parent volume.
This is the simplest foolproof solution that will inherit some
scale without ever causing shear.
* None: completely remove scale and shear.
* None (Legacy): old disabled Inherit Scale checkbox.
This mode does not handle parent shear in any way, so the child
is likely to end up having both scale and shear. It is retained
for backward compatibility.
Since many rigging-related addons access the use_inherit_scale
property from Python, it is retained as a backward compatibility
stub that provides the old functionality.
As a side effect of reworking the code, this also fixes a matrix
multiplication order bug in the Inherit Rotation code, which caused
the parent local scale to be applied in world space. In rigger
opinion this option is useless in production rigs, so this fix
should not be a problem.

In order to correctly drive corrective shape keys from a freely
rotating organic joint it is very often found necessary to
decompose the rotation into separate bending and twisting
motions. This type of decomposition cannot be reproduced by
any Euler order or a single quaternion.
Instead this is done by using a helper bone with a Damped Track
constraint aimed at the tail of the control to pick up the bending,
and its helper child with Copy Transforms to separate the twist.
Requiring two additional bones to drive a shape key or a correction
bone seems inconvenient, so this implements the necessary math as new
options in the recently introduced Rotation Mode dropdown of the
Transform Channel driver variable type. The data is also accessible
as a Transformation constraint input.
The output is in the form of Quaternion-derived 'pseudo-angles',
which for `Swing and Y Twist` would represent the following:
* W: true bend angle, independent of bend direction.
* Y: true twist angle.
* X, Z: pseudo-angles representing the proportion of bending around X/Z.

This is a general redesign of the File Browser GUI and interaction
methods. For screenshots, check patch D5601.
Main changes in short:
* File Browser as floating window
* New layout of regions
* Popovers for view and filter options
* Vertical list view with interactive column header
* New and updated icons
* Keymap consistency fixes
* Many tweaks and fixes to the drawing of views
----
General:
* The file browser now opens as temporary floating window. It closes on
Esc. The header is hidden then.
* When the file browser is opened as regular editor, the header remains
visible.
* All file browser regions are now defined in Python (the button
layout).
* Adjusted related operator UI names.
Keymap:
Keymap is now consistent with other list-based views in Blender, such as
the Outliner.
* Left click to select, double-click to open
* Right-click context menus
* Shift-click to fill selection
* Ctrl-click to extend selection
Operator options:
These previously overlapped with the source list, which caused numerous
issues with resizing and presenting many settings in a small panel area.
It was also generally inconsistent with Blender.
* Moved to new sidebar, which can easily be shown or hidden using a
prominent Options toggle.
* IO operators have new layouts to match this new sidebar, using
sub-panels. This will have to be committed separately (Add-on
repository).
* If operators want to show the options by default, they have the option
to do so (see `WM_FILESEL_SHOW_PROPS`, `hide_props_region`), otherwise
they are hidden by default.
General Layout:
The layout has been changed to be simpler, more standard, and fits
better in with Blender 2.8.
* More conventional layout (file path at top, file name at the bottom,
execute/cancel buttons in bottom right).
* Use of popovers to group controls, and allow for more descriptive
naming.
* Search box is always live now, just like Outliner.
Views:
* Date Modified column combines both date and time, also uses user
friendly strings for recent dates (i.e. "Yesterday", "Today").
* Details columns (file size, modification date/time) are now toggleable
for all display types, they are not hardcoded per display type.
* File sizes now show as B, KB, MB, ... rather than B, KiB, MiB, … They
are now also calculated using base 10 of course.
* Option to sort in inverse order.
Vertical List View:
* This view now used a much simpler single vertical list with columns
for information.
* Users can click on the headers of these columns to order by that
category, and click again to reverse the ordering.
Icons:
* Updated icons by Jendrzych, with better centering.
* Files and folders have new icons in Icon view.
* Both files and folders have reworked superimposed icons that show
users the file/folder type.
* 3D file documents correctly use the 3d file icon, which was unused
previously.
* Workspaces now show their icon on Link/Append - also when listed in
the Outliner.
Minor Python-API breakage:
* `bpy.types.FileSelectParams.display_type`: `LIST_SHORT` and
`LIST_LONG` are replaced by `LIST_VERTICAL` and `LIST_HORIZONTAL`.
Removes the feature where directories would automatically be created if
they are entered into the file path text button, but don't exist. We
were not sure if users use it enough to keep it. We can definitely bring
it back.

Previously this was done in the deps builder due to the fact we needed
both 32 and 64 bit versions of this dll and CMAKE does not support that
in a single build folder. Now that 32 bit support has been dropped, this
can be safely moved into the codebase.

Actual issue is with triangle beautify,
avoid precision error by scaling the epsilon
by the face area when it's over 1
The mesh in the report was very large (approx 2000 on each side),
causing precision issues with a fixed epsilon.
Since OpenImageDenoise requires a CPU with SSE 4.1 or newer,
let the node act as passthrough on unsupported CPUs and display
a message in the node itself.
