If there's a websocket being waited on the shut down won't actually
happen. Add a new event for shut down and send it to break the websocket
out of its loop.
By default logging configuration is defined by
resources/default_logging.yaml. Very noisy loggers (like the
uvicorn.access logger) are kept out of the console and UI logs by
default. Developers (or weird users) can customize their default logging
config by copying the file to resources/logging.yaml and editing as
needed. It would be preferable to load this file form the Liberation
user directory, but because first-time initialization requires the UI,
we want to configure logging before we necessarily know where to find
that.
I have no idea why the docs think strings are better. pyinstaller wasn't
able to detect the import through the string so the code ended up being
stripped from the package. Use an explicit import to prevent that.
A possible explanation for the infrequent CTDs we've been seeing since
adding fast forward is that QWebChannel doesn't keep a reference to the
python objects that it passes to js, so if the object is GC'd before the
front end is done with it, it crashes.
We don't really like QWebChannel anyway, so this begins replacing that
with FastAPI.
