Listing the "Blender Foundation" as copyright holder implied the Blender
Foundation holds copyright to files which may include work from many
developers.
While keeping copyright on headers makes sense for isolated libraries,
Blender's own code may be refactored or moved between files in a way
that makes the per file copyright holders less meaningful.
Copyright references to the "Blender Foundation" have been replaced with
"Blender Authors", with the exception of `./extern/` since these this
contains libraries which are more isolated, any changed to license
headers there can be handled on a case-by-case basis.
Some directories in `./intern/` have also been excluded:
- `./intern/cycles/` it's own `AUTHORS` file is planned.
- `./intern/opensubdiv/`.
An "AUTHORS" file has been added, using the chromium projects authors
file as a template.
Design task: #110784
Ref !110783.
Tests should never depend on the users startup.blend which can have
settings that interfere with tests.
Failure to load the user startup.blend for e.g. prevented
bl_alembic_io_test from passing.
There should be no functional changes for the typical usecase,
but it allows to have more tricky setups like pointing to a
BAT script to override some configuration.
The issue is that BAT scripts do not support new lines in the
command line arguments. That's where single-line python expression
helps.
For example, it is possible to point benchmark script to a blender.bat
which contains
blender.exe --python-expr "import bpy; bpy.context.preferences.addons['cycles'].preferences.use_oneapirt = False" %*
to have side-by-side numbers of oneAPI with and without HW RT.
Without this change the %* is which did not work: the BAT
script did not "see" part of the command line past the new line.

The scene contains some interesting names, which requires to be
written as utf-8. And on Windows file descriptor is not guaranteed
to be using utf-8. Or, will error out if the invalid utf-8 sequence
is written.
This change makes it so running benchmarks on windows it fully successful.

Windows does not really have an idea of shebangs, and it needs to
go via a file extension to see that the script is to be executed
by Python.
This change simplifies execution from `python3 benchmark ...`
to `benchmark.py ...`.

Ideally, we would also get variance information out of the test, but that
seems a bit more complex to implement. For now just run the test a couple
of times and average the timings.
The test now runs between 5 and 100 times, depending on how long it
to run the test once.
I noticed that sometimes the geometry nodes benchmark would not work
if there were some left-over debug prints in the code. The reason it did
not work was because the prints were mixed with the test output print.
I also tried using explicit flusing and `atexit` for printing the test output,
but that didn't solve it. Just printing additional newlines to better separate
the test output from other printed output helped though.
Add a script for a very simple object evaluation benchmark.
There could be more advanced ways of measuring the time
per-node or per modifier, but this just loads the file, tags
the active object for a reevaluation, and times how long
that takes.

This commit adds the ability to test Eevee viewport playback performance tests.
Tests should be placed in `lib/benchmarks/eevee/*/*.blend`. {rBL62962} added
initial test files. See https://wiki.blender.org/wiki/Tools/Tests/Performance how
to set it up.
To record the playback performance the test start the viewport playback, and adds
a post frame change handler.
This handler will go over the next steps:
* Ensures the viewport is set to rendered mode.
* Wait for shaders to be compiled. Utilizes `bpy.app.is_job_running` function when
available (v3.3) to wait for shader compilation to finish. When not available will wait
for one minute.
* Draw several warmup frames
* Record for 10 seconds tracking the number of frames drawn and performance counters.
* When ready print the result to the console. The results will be extracted when the
benchmark has run.

This includes much improved GPU rendering performance, viewport interactivity,
new shadow catcher, revamped sampling settings, subsurface scattering anisotropy,
new GPU volume sampling, improved PMJ sampling pattern, and more.
Some features have also been removed or changed, breaking backwards compatibility.
Including the removal of the OpenCL backend, for which alternatives are under
development.

* Make "run" command (re-)run all tests, add "update" command to only
run queued and outdated tests equivalent to the old "run" command.
* Support specifying environment variables for revisions, to easily
compare multiple parameter values.
* Better sorting of revisions in graph.
* Allow specifying a folder and automatically setting the proper executable
name depending on the operating system
* Use executables from configs for listing devices instead of a blender
command being available
The general graphing mechanism will create one graph for each output
variable. So it's not limited to time and memory, but that is what the
Cycles tests now output.
These are scripts for benchmarking Blender features on real-world .blend
files. They were originally written for benchmarking Cycles performance, and
were made generic so they can be used for more Blender features.
The benchmarks can be run locally by developers. But the plan is to also run
these as part of continuous integration to track performance over time.
Currently there are tests for Cycles rendering and .blend file loading.
Documentation:
https://wiki.blender.org/wiki/Tools/Tests/Performance
Main features:
* User created configurations to quickly run, re-run and analyze a selected
subset of tests.
* Supports both benchmarking with existing builds, and automatic building of
specified git commits, tags and branches.
* Generate HTML page with bar and line graphs from test results.
* Controlled using simple command line tool.
* For writing tests, convenient abstraction to run a Python function in Blender
with arguments and return value.
