for Open edX operators who still have users with legacy PDF certificates, retirement requires first extracting information from the user's GeneratedCertificate record in order to delete the 4 associated files for each PDF certificate, and then removing the links to the relevant files. this creates a management command to do that work.
After thinking about it, I have removed the update to `status` from this management command, as per the original specification of the ticket. I added it for completeness originally, but was already uncomfortable, because it's not exactly accurate. The `CertificateStatuses` enum does define a `deleted` status:
```
deleted - The PDF certificate has been deleted.
```
but I think it's inappropriate to use here.
#### Why not use `CertificateStatuses.deleted` in the first place
There are multiple places in the code where it's clear that almost all of the statuses are legacy and unused (eg. [Example 1](6c6fd84e53/lms/djangoapps/certificates/data.py (L12-L34)), [Example 2](1029de5537/common/djangoapps/student/helpers.py (L491-L492))). There are innumerable APIs in the system that have expectations about what might possibly be returned from a `GeneratedCertificate.status` object, and none of them is expecting `deleted`
#### Why not revoke the certificate
Ultimately, the certificate isn't revoked, which has a specific meaning around saying it was unearned. The certificate was earned; it has simply been deleted. We should not be kicking off program certificate invalidation, because that's not what's happening. We should be trusting the normal user retirement process to remove/purge PII from any program certificates that might exist. The nature of web certificates simply means that we are going through this process outside of the normal retirement flow. The normal retirement flow can be trusted to implement any certificate object revocation/removal/PII-purging, and doing an extra step outside of that flow is counterproductive.
#### Why not robustly add a flow for `CertificateStatuses.deleted`
When PDF certificates were removed from the system, they weren't removed in their entirety. Instead, we have this vestigial remains of PDF certificates code, just enough to allow learners to display and use the ones that they already have, without any of the support systems for modifying them. Adding a `deleted` status, verifying that all other APIs wouldn't break in the presence of a certificate with that status, adding the signals to process and propagate the change: all of this would be adding more tech debt upon the already existing technical debt which is the PDF certs code. Better to simply add this one necessary data integrity change, and focus on a process which might allow us to eventually remove the web certificates code.
#### Why it is good enough to ignore the status
The original ask was simply to enforce data integrity: to remove links to files that have been deleted, as an indication that they've been deleted. I only added `status` update out of a (misplaced but well-intentioned) completionist urge.
FIXES: APER-3889
Quoting the README:
> If you are reading this and the 'Maple' Open edX release is out, you
> can safely delete this whole djangoapp. It only exists to hold old
> model migrations and any post-Maple installation will no longer have
> any model in the database for this app.
>
> But for some minor historical context, this djangoapp used to hold
> some integration with sailthru that we no longer needed.
We've released Sumac. This is overdue.
* fix: catch a possible exception in beta course configuration
when the learner is a beta tester, and the beta test has been set up with a large duration, the courseware djangoapp can return an overflow error on a timedelta call. In those circumstances, this defaults to returning an unmodified date.
FIXES: APER-3848
Returning the list with a 'completion' string was added in 9bc0f85. However,
the `get_accessible_sequences` method expects a list of dicts with an 'id' key.
This removes special logging for course course-v1:UQx+BUSLEAD5x+2T2019
as part of an edX investigation (EDUCATOR-4568 in their internal JIRA).
That issue was closed on 2021-01-08 by Mat Carter with the comment:
> Aged out, closing. If this issue continues, please create a new
> ticket optionally referencing this one.
(Note that Mat has since left edX/2U.)
The EDUCATOR-4602 ticket was created to track the cleanup of this
logging code.
* feat: Reapply "Integrate Forum V2 into edx-platform"
This reverts commit 818aa343a2.
* feat: make it possible to globally disable forum v2 with setting
We introduce a setting that allows us to bypass any course waffle flag
check. The advantage of such a setting is that we don't need to find the
course ID: in some cases, we might not have access to the course ID, and
we need to look for it... in forum v2.
See discussion here: https://github.com/openedx/forum/issues/137
* chore: bump openedx-forum to 0.1.5
This should fix an issue with index creation on edX.org.
This commit introduces the new Forum V2 application, allowing users to choose between the legacy Forum V1 and the new Forum V2 at the course level.
Key Changes:
- Added waffle flag `discussions.enable_forum_v2` to enable Forum V2 for selected courses, allowing coexistence with Forum V1.
- Default data storage for Forum V2 is set to MongoDB, with an option to switch to MySQL using the waffle flag `forum_v2.enable_mysql_backend`.
- Introduced management command `forum_migrate_course_from_mongodb_to_mysql` for per-course data migration from MongoDB to MySQL.
Note: This PR does not include all unit tests for the Forum V2 native API due to ongoing migration efforts. Further updates will follow to ensure full test coverage before final release.
