The biggest challenge is dealing with the mismatch between how Libraries store
assets (per-Component) and how Courses store assets (global Files and Uploads
space). To bridge this, we're going to kludge a component-local namespace in
Files and Uploads by making use of the obscure feature that you can create
folders there at an API level, even if no such UI exists.
In this commit:
* Assets work when copy-pasting between library components.
* Assets work when copy-pasting from a library to a course, with the convention
being to put that file in a subdirectory of the form:
components/{block_type}/{block_id}/file.
Note that the Studio course Files page still just shows the filename.
* Assets work when copy-pasting from a course to a library.
Top level assets are put into a static folder in the Component, per Learning
Core conventions.
Limitations:
* Roundtrips don't work properly.
* There's no normalized form, so directories will start nesting if you copy
from library and paste into course, then copy the pasted thing and paste back
into library, etc. This was deemed acceptable for Sumac.
Low level stuff:
* XBlockSerializerForLearningCore has been removed, with the url_name stripping
functionality added as an optional param to XBlockSerializer (the other stuff
was for children and "vertical" -> "unit" conversion, neither of which are
relevant now).
* url_name is now stripped out of anything added to the clipboard, so that we
don't end up writing it in block.xml when it is redundant (and would be
stripped out with the next write anyway).
For the Libraries Relaunch Beta. This should not affect any site which
has kept New Libraries disabled.
Issue: https://github.com/openedx/frontend-app-authoring/issues/1170
We have user-oriented messaging stuffed into the BadUpstream exception. We may
as well use it rather than just giving an opaque error about xblock references.
We also want to log this situation, since we'd expect that the library block
usage key that Studio provides should generally be valid. If it consistently
isn't, then that's an issue that operators are going to want to look into.
This is a new XBlock that presents a random subset of its children. As of this commit, the block
can only be added as an Advanced component. For Sumac, we plan to enable it as part of the
Libraries Relaunch Beta, under the name "Problem Bank (Beta)"
The block does not care if its children are from V1 library, V2 library, or the course itself.
It shares the randomization logic with LegacyLibraryContentBlock. It is also fully backwards-compatible with LegacyLibraryContentBlock. So, once V1 libraries are migrated to V2 libraries (after Teak), we eventually
could point the `library_content` entry point at ItemBankBlock.

Upgrade codejail to add 22.04 support
Commit generated by workflow `openedx/edx-platform/.github/workflows/upgrade-one-python-dependency.yml@refs/heads/master`
Adds a new Studio-only libraries static asset endpoint at
/library_assets/blocks/{usage_key}. This endpoint will serve assets
only from the Draft branch, and is only available to people who have
read permission to the containing library.
This also moves the existing library asset endpoint that did lookups
by Component Version to /library_assets/component_versions/{uuid}
This change was motivated by the desire to make it easier to make the
editor preview work for images by having a single URL that will
consistently point to the latest version of the asset, rather than
having a new URL after every save (which the Component Version lookup
added content_title, progress_status in get_learner_data_records for derived classed of learner data exporters.

We don't need a dependency on `newrelic` in edx-platform, since it's
already brought in via edx-django-utils, which is where telemetry
dependencies belong anyhow.
Ran `make compile-requirements` to apply changes to lockfiles.
(Additional context: We may end up DEPRing the direct dependencies in
edx-django-utils as well and requiring deployers to install newrelic
separately. In any case, there aren't any places in openedx code that is
installed into the LMS or CMS that import newrelic directly.)
Also, update README to note system package dependencies that are required
for installing edx-platform deps. I had to reinstall my laptop and ran
into this again and wanted to actually document it this time.
* fix: problem block could not be used with versioned handler URls
* refactor: simplify REST API handling of usage keys
* feat: add more version awareness and update tests
* fix: make the preview changes modal bigger as requested
* refactor: parse version at the urlconf layer too
* feat: Copy tags when sync library
* feat: Avoid delete object tag if is copied
* chore: Bump version of openedx-learning to 0.16.0
* test: Tests for copy paste library blocks
* feat: Sync tags when sync upstream
* refactor: rename CourseHomeSerializer to StudioHomeSerializer
to better reflect how this serializer/API is used in the Authoring MFE
* feat: adds waffle flags for legacy libraries v1 and new libraries v2 in new Studio Home
These waffle flags replace the MFE env flag LIBRARY_MODE.
* refactor: use contentstore.toggles.libraries_v1_enabled()
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".
The first attempt at creating a new MFE-driven page for Studio Unit
rendering involved rendering each XBlock separately in its own iframe.
This turned out to be prohibitively slow because of the many redundant
assets and JavaScript processing (e.g. MathJax) that happens for each
XBlock component.
In order to mitigate some of these issues, we decided to try a hybrid
approach where we render the entire Unit's worth of XBlocks at once on
the server side in a Studio view + template, and then invoke that from
frontend-app-authoring as an iframe. The frontend-app-authoring MFE
would still be responsible for displaying most of the interactive UI,
but the per-component actions like "edit" would be triggered by buttons
on the server-rendered Unit display. When one of those buttons is
pressed, the server-rendered UI code in the iframe would use
postMessage to communicate to the frontend-app-authoring MFE, which
would then display the appropriate actions.
To make this work, we're making a new view and template that copies
a lot of existing code used to display the Unit in pre-MFE Studio, and
then modifying that to remove things like the header/footer so that it
can be invoked from an iframe.
This entire design is a compromise in order to do as much of the UI
development in frontend-app-authoring as possible while keeping
XBlock rendering performance tolerable. We hope that we can find
better solutions for this later.

Add support for displaying static assets in the Learing Core XBlock
runtime via "/static/asset-name" style substitutions in the OLX. This is
currently used for new Content Library components.
Static asset display is version-aware, so viewing older versions of the
XBlock content via the embed view will show the appropriate assets for
that version.
This introdues the idea of "upstream" and "downstream" content,
where downstreams (like course components) can pull content updates from
upstreams (like learning core-backed content library blocks). This
supports the upcoming Content Libraries Relaunch Beta for Sumac.
New features include:
* A new XBlockMixin: UpstreamSyncMixin.
* A new CMS Python API: cms.lib.xblock.upstream_sync
* A new CMS JSON API: /api/contentstore/v2/downstreams
* A temporary, very basic UI for syncing from Content Library blocks
Implements:
