This ensures that services started with `tutor dev start`
are as capable for breakpoint debugging, et al, as services
started with `tutor dev runserver` are. We plan to remove
`tutor dev runserver`.
Previously, user-uploaded files were stored in the /openedx/xqueue/openedx
folder (considered by django to be a media subfolder). This folder was not
being mounted on the host, thus causing files to be lost on container restart.
Also, files were simply not reported by the `tutor submissions show` utility.
We now bind-mount the media folder from the host. Media assets are served by
uwsgi, which replaced gunicorn.
When object storage is in use, we will have to point xqueue to the remote
storage solution. This means that we need to add patches to the tutor-minio
plugin.
Close#2.
Xqueue was mostly broken in the previous releases. In this version, we
address the following issues:
- Proper initialisation by creating the right users
- Shift from 8040 to the more standard 8000 port
- Expose xqueue service on the internet for accessing its API
- Properly define the xqueue name ("openedx")
- Make sure that all logs go to the console
- Add convenient CLI for using the awkward Xqueue API
- Properly document how to use Xqueue
