Description

Adds waffle flags to replace the Authoring MFE's LIBRARY_MODE env config variable, and exposes them with the contentstore "home" REST API.

Since waffle flags are disabled by default, and we want both v1 and v2 libraries enabled by default in the Authoring MFE, we've named these flags as disable_*_libraries.

  • contentstore.new_studio_mfe.disable_legacy_libraries -> negated to provide libraries_v1_enabled in the REST API
  • contentstore.new_studio_mfe.disable_new_libraries -> negated and combined with settings.MEILISEARCH_ENABLED to provide libraries_v2_enabled in the REST API.

Combined with openedx/frontend-app-authoring#1329, this change impacts Course Authors.

Supporting information

Relates to:

Private-ref: FAL-3858

Testing instructions

See openedx/frontend-app-authoring#1329

Deadline

ASAP

Concerns

  1. There is already a settings.FEATURES flag called ENABLE_CONTENT_LIBRARIES. How this flag should affect use of libraries v1 and/or v2 is under discussion.

to better reflect how this serializer/API is used in the Authoring MFE
…in new Studio Home

These waffle flags replace the MFE env flag LIBRARY_MODE.
and ENABLE_CONTENT_LIBRARIES feature toggle where possible.

ENABLE_CONTENT_LIBRARIES has been incorporated into both the
libraries_v1_enabled() and libraries_v2_enabled() toggles:
FEATURES['ENABLE_CONTENT_LIBRARIES'] must be true for either version of
libraries to be "enabled".

Nice work!

I note that contentstore.new_studio_mfe.disable_new_libraries doesn't disable the v2 libraries REST APIs, but I think that's good.

I tested various combinations of this, and I did confirm that contentstore.new_studio_mfe.disable_legacy_libraries does disable the legacy UI library views like http://studio.local.openedx.io:8001/library/library-v1:foo+bar (now gives 404 if that waffle flag is enabled).

I note that because this depends on Meilisearch, even though v2 libraries will now generally be on by default, they will remain off on edx.org (which is not ready to roll them out yet), because it doesn't have Meilisearch configured. So merging this should not affect 2U.
