In production, the ALTERNATE_WORKER_QUEUES setting is overridden by ""
(empty string). This might prevent LMS from sending tasks to the CMS. We
have not seen this issue emerge yet, but better be safe than sorry.
We must be careful not to process the tasks from the CMS, just like for
the CMS worker which does not process the tasks from the LMS.
Half of the tasks from edx.lms.core.default celery queue were being
processed by the CMS worker. Unfortunately, this CMS worker crashes on
some of those tasks. For instance, activation emails complain of a
missing "django_markup" template tag library because "xss_utils" is not
part of the installed app in the CMS.
The problem is that we need this edx.lms.core.default queue to be part
of the CELERY_QUEUES in the cms in order to send tasks from the CMS to
the LMS. The trick to resolve this situation is to ask the CMS celery
worker to not process the tasks from this queue.
To debug this issue, run in the LMS:
from student.tasks import send_activation_email
send_activation_email("{}")
Then watch the logs of the lms and cms workers. If the CMS workers picks
up this task (50% of the time prior to this change) then we have an
issue.

"tutor ui" was failing miserably, printing a lot of garbled characters
in the shell. In fact, a FileNotFound error was being raised and
automatically caught by the ui command. When removing the catch all,
this was the error that was raised:
FileNotFoundError: [Errno 2] No such file or directory:
'/tmp/_MEIimsqmq/wcwidth/version.json' │
This is resolved on SO:
https://stackoverflow.com/questions/62155242/pyinstaller-cant-find-wcwidth-version-json-when-running-executable
This was due to incorrectly loading the coursewarehistoryextended in the
installed applications. Also, the database router in charge of routing
requests to the student_history_module database must be disabled.
In CI, the webpack-stats.json file sometimes contains just:
{"status":"compiling"}
This was due to the fact that the `subprocess.call(...)` command in
openedx-assets did not check whether the command was killed -- for lack
of memory for instance. This is resolved by replacing "call(...)" by
"check_call(...)".
Here, we upgrade the Open edX platform from Ironwood to Juniper. This
upgrade does not come with many feature changes, but there are many
technical improvements under the hood:
- Upgrade from Python 2.7 to 3.5
- Upgrade from Mongodb v3.2 to v3.6
- Upgrade Ruby to 2.5.7
We took the opportunity to completely rething the way locally running
platforms should be accessed for testing purposes. It is no longer
possible to access a running platform from http://localhost and
http://studio.localhost. Instead, users should access
http://local.overhang.io and https://studio.local.overhang.io. This
drastically simplifies internal communication between Docker containers.
To upgrade, users should simply run:
tutor local quickstart
For Kubernetes platform, the upgrade process is outlined when running:
tutor k8s upgrade --from=ironwood
