Firstly, we're now explicitly instructing the comments service to not
return thread responses/comments if the request isn't AJAX. So, if you
load the URL for a single discussion thread in your browser, this would
be a non-AJAX call and we'll avoid loading the responses for the entire
thread behind-the-scenes. Big win here for large threads.
Next, we removed a redundant "get threads" call which was also happening
behind-the-scenes. This call was redundant as the front-end JS also
grabs the thread list when a topic is chosen, so we were making an
extranenous call for no benefit. Poof, gone!
Finally, we added some caching of database queries that are required to
drive a lot of the permissions/cohorts machinery around discussion.
This will have a minimal effect but introduced a cleaner way to apply
general memoization at the per-request level which will let us further
cache things as we identify them as issues.
We're often grabbing the metadata of a specific thread to then be able
to perform other operations, but we never need the actual responses or
comments of a thread unless we're displaying it in the normal forum
view.
This change sets a default of with_responses=False, which instructs the
comment service to not send back the responses/comments for the given
thread. We only ask for responses in the case of rendering a single
thread or inline discussion.
2. Update COMPREHNSIVE_THEME_DIR to COMPREHENSIVE_THEME_DIRS
3. Update paver commands to support multi theme dirs
4. Updating template loaders
5. Add ENABLE_COMPREHENSIVE_THEMING flag to enable or disable theming via settings
6. Update tests
7. Add backward compatibility for COMPREHEHNSIVE_THEME_DIR
By default, disable all caching in tests, to preserve test independence.
In order to enable caching, inherit from CacheSetupMixin, and specify
which cache configuration is needed.
[EV-32]
Caches all permissions per user per course. Adds caching functionality to has_permission and replaces all instances of cached_has_permission with has_permission.
This reverts commit 086a2ba783, reversing
