Sybren A. Stüvel 3a3e664ae2 Add option to make a job setting auto-evaluatable by the user
Add a new job setting option `autoevalLockable`. Setting this to `true` in
the job compiler's `JOB_TYPE` settings has the following effect:

- By default, the setting will not be editable in Blender's job submission
  interface. Instead, a toggle button with a 'car' icon will be shown.
- When the 'car' button is toggled off, the setting becomes editable again.

In its default, uneditable state, the setting will be auto-evaluated before
submission.

This makes it possible to 'lock in' auto-evaluation. The main use case is
for the frame range of the render job. By default this will be locked to
the scene frame range, but it can still be overridden if a different
range is wanted.

Flamenco 3 Blender add-on

Setting up development environment

~/workspace/blender-git/build_linux/bin/3.1/python/bin/python3.9 -m venv --upgrade-deps venv
. ./venv/bin/activate
pip install poetry
poetry install

Generating the OpenAPI client

  1. Make sure Java is installed (so java --version shows something sensible).
  2. In the root directory of the repository, run make generate-py

Type annotations and lazy imports

This add-on tries to only load Python packages from wheel files when necessary. Loading things from wheels is tricky, as they basically pollute the sys.modules dictionary and thus can "leak" to other add-ons. This can cause conflicts when, for example, another add-on is using a different version of the same package.

The result is that sometimes there are some strange hoops to jump through. The most obvious one is for type annotations. This is why you'll see code like:

if TYPE_CHECKING:
    from .bat_interface import _PackThread
else:
    _PackThread = object

This makes it possible to declare a function with def func() -> _PackThread, without having to load bat_interface immediately at import time.
