|Category||Deprecated Code||Still in use?||Places where it's in use (if known)||Viable non-deprecated alternative?|
|Fix Cost (1-5)||Removal Status|
|Authentication|External Auth Yes (only by MIT) MITx uses CAS, which is only in external-auth. third_party_auth 2 3 (preventing removal of old login/reg) 2 We have DEPR-6 for this. Have MIT's blessing. Studio redirects to LMS instead of maintaining a separate login and registration flow.
Old login & registration Yes Open edX and external auth paths. Still default. Logistration API 4 (default, fixes are accidentally made to old one) 5 3 by Diana Huang as part of /wiki/spaces/HACK/pages/600375541 PR: https://github.com/edx/edx-platform/pull/18321
|django-oauth2-provider (DOP) / OpenID Connect||Yes|
OAuth clients, which should be removed if inactive and shifted to DOT if active
most of our IDAs are using DOP
|django-oauth2-toolkit (DOT)||2||3||5||See /wiki/spaces/PLAT/pages/160912480.|
|Yes||All over||OAuthAPIClient (from same package)||3||3||2||Uses Slumber, which isn't supported any longer.|
|APIs|Mobile's old video locker APIs Yes latent code in mobile apps - need to be removed (Jira ticket(s) exist somewhere) Course Blocks API 3 (since REST API) 2 2 Mobile apps updated to use the new Course Blocks API 3 years ago. They just need to remove references and latent code to the old API. Discovery needed to make sure that there isn't data that the apps are relying on.

|Old Discussions API||Yes||Desktop view of Discussions||Newer Discussions API (used by Mobile)||2||2||4|
|Frontend||RequireJS||Yes||edx-platform, edx-mktg||webpack, JS||1||5||3||Can be done incrementally - on a page-by-page basis.|
|UI Pattern Library / edx-pattern-library||Yes|
edx-platform, insights, ecomerce, other repos
Hard to (1) know which HTML elements are used by pattern library versus not - since there's no namespacing, (2) colors/fonts/etc are different.
INCR-43Getting issue details...
|edX-ui-toolkit||edx-platform, insights||Paragon||2||3||4||Re-platforming work by Arch Squad means that we will be rewriting front-end code|
|FontAwesome webfonts||Yes||FontAwesome SVG||3||1||2||SVG is smaller size and other benefits. This involves porting from FA 4 to 5, plus using new react bindings. (in paragon or manually)|
ON HOLD. Open Source community has been building on it. Has to run inefficient queries on a badly optimized DB.
Product has said that we can't remove this until its functionality is duplicated elsewhere.
|edx-Notifications||Yes||By Yonkers||edx-ACE||2||1||1||ON HOLD. edX has agreed to own this and it can't be removed until either (1) our forked Open edX hosted instance goes away or (2) ACE reaches complete feature parity with it. (Notifications tray and in-browser notifications channel).|
|Courseware||Old Mongo||Yes (a little)|
Old production courses,
check with community, units tests still use the old modulestore
DEPR-58Getting issue details...
We have a doc on a potential /wiki/spaces/~dormsbee/pages/525861934 for when the time comes.
# of course runs using old mongo: 615
We will want a backwards compatible release that enables migration for Open Source installations to Split (and then probably BlockStore).
|XModule||Yes||some edX learning components: video, HTML, CAPA problem, etc.||XBlock||1||4||5|
Discovery Doc: https://docs.google.com/document/d/1t2P9i2BZKYf_pW61m
Unification of descriptors and classes, conversion of handlers, serialization is different.
Can shave off some of the more painful side of things in smaller chunks.
|lti_module.py||?||on edx.org in a lot of older courses||xblock-lti-consumer||1||2||2||It's marked as deprecated in module/class doc strings.|
OfficeMix Low use, errors in existing blocks OfficeMix is retired/no longer supported by Microsoft 1 2 2 Removed in instructor docs (DOC-3973). This code is installed remotely. The endpoint that it contacts no longer exists, so we can be heavy-handed about removing it.
|Course Experience waffle flags||?||1||?||?||Feature Toggle reports would help. Could be used for certain courses in Prod or Edge.|
|Features|Microsites Sites/SiteConfiguration 1 2 1 What does the migration look like?
|Shopping cart||Ecommerce service||?||?||?|
DEPR-43Getting issue details...
NR stats on Prod:
shoppingcart.views:donate - 345x
shoppingcart.views:show_receipt - 111x
shoppingcart.views:postpay_callback - 88x
|Yes||by 229 courses||Enrollment Track Partition||1||1||1|
It's deprecated. Need to migrate the 229 courses.
Removal work was investigated by the Masters squad with tasks captured at VerifiedTrackCohortRemoval.
Learner Analytics Dashboard No, for a diff paid experiment that is over Unknown The existing progress page 1 1 1 Implemented for a diff paid experiment that is now over. Most of this is a giant hack that should go away. https://github.com/edx/edx-platform/tree/master/openedx/features/learner_analytics
|Infrastructure|Datadog No. edX devs don't use this anymore 2 2 1 Dependency that does not work with Python 3, so we need to get rid of this. In progress
DEPR-9Getting issue details...
|track.backends.django.TrackingLog||Maybe Open edX consumers (Stanford?)||Not in edx.org||1||2||1||Can be pulled out and put into a separate installable repo/app, probably.|
Lettuce Tests Yes edx-platform testing bok-choy 1 3 3 ON HOLD. Replace both with consumer contract tests on the roadmap. Can probably remove tests that are not useful any longer entirely.
|Dark Lang||Yes||edx-platform + IDAs||N/A||Currently there isn't a replacement that exists that duplicates this functionality planned or existing.|
Opaque Key's deprecated methods Yes This is only the methods from_deprecated_string and to_deprecated_string. We are not removing the old "org/course/num" slash format.
|Haystack||Yes||Notes and Discovery ...?||Pure elasticsearch||2||5||3||Haystack is forcing us to stay on an ancient version of elasticsearch. And haystack itself is no longer maintained. We should just use direct elasticsearch instead of the haystack abstraction layer.|
|display_name_with_default_escaped||Yes||edx-platform, edx-microsite, edx-themes||display_name_with_default|
