Several tasks are explicitly named as (or like)
their old, deprecated import path.
The issue here is that django-user-tasks listens for task
invocations, and attempts to import the task based on its name.
If the task name is completely wrong, user-tasks will catch
the ImportError and move on.
If the task is a valid *deprecated* import, though, then
user-tasks will choke on the raised `DeprecatedEdxPlatformImportError`.
Thus, we must rename three tasks to their new full path:
1. entitlements.expire_old_enrollments
2. third_party_auth.fetch_saml_metadata
3. student.send_activation_email
The first two are run daily, and so are safe to be
renamed in place.
The third task must be renamed using an expand-contract
pattern; otherwise, we would drop hundreds of tasks
during the App vs. Worker out-of-sync version window
that happens at deployments.
This commit is the expand phase.
- Use different attribute names for new and old versions of function
- Use a shorter name overall (for ease of analysis)
- Add monitor for fetched-existing case
- Only record computed-stored if `get_or_create` succeeds, but also
break it into created vs. fetched cases by checking return value
- Correct name of monitor in `except` clause -- that should only happen
for a race inside `get_or_create` itself. There's a different race in
the `anonymous_uid_for_user` between fetch and compute/save.
- Other name tweaks
ARCHBOM-1674
- Make it easier to rotate `SECRET_KEY` by documenting this usage
for both sensitivity and rotation process. (ARCHBOM-1676).
- Just use a hash of the secret rather than HMAC + MD5. We're not
authenticating a message, so HMAC isn't really needed -- it just needs
to be unique, deterministic, and irreversible. SHAKE allows generation
of an arbitrary length hash without needing to truncate.
Also, rename tracking session ID generator for clarity -- there's no
encryption happening here.
Add additional test for existing claim of uniqueness.
* import task decorator from celery APP instance instead of celery package in CMS
* replaced task decorator with shared_task in cms and common
* Fixed import of shared_task
* Fixed import
