The Moodle UI should be functional in a viewport of 320px by 256px to
meet WCAG 1.4.10
this patch contains improvements to:
-prevent horizontal scrolling
-better wrapping of page header
-message drawer funtional on tiny screens
-remove indenting on courses
-prevent elements overlapping on quiz editing
-better navigation tabs
-fix colour picker
-quiz editing
Implemented with moodle_read_slave_trait
Functionality is triggered by supplying config dboption['readonly'].
See config-dist.php for more info on supported dboptions.
pgsql and mysqli drivers are using this feature. Also added support for
connection timeout for these two drivers.
In 39770792ca read-only sessions were allowed.
In the redis case, as called from the mobile application,
this can lead to returning 'false' for session rather than ''.
This patch adds better core support for copying courses.
There is now a simplified and dedicated UI for copying
courses. This can be accessed from the course context
menu or course management screens.
All backups are done asynchronously and there can be multiple
copies of a course in flight at once.
These function updates are in preparation for the participants_search
class, which will be used to support multiple values per filter when
filtering the participants page.
With the templaterev issue resolved we should enable the prefetch module
when cachejs is enabled to avoid a different experience when cachejs is
enabled vs. disabled.
Previously there was little point in doing this due to a range of other
bugs (string normalisation, and misuse of templaterev).
With these issues resolved we should enabel the caching.
The M.cfg.templaterev variable should only be used to present persistent
caching, not caching of content within the same page load.
Preventing caching of same-page content makes it difficult to develop
for real user experiences as content is slow to load and does not give a
realistic and consistent loading experience.
This change affects the loading of partials specifically which notably
includes the loading spinner. Without this patch the loading icon is
often not seen at all because it does not load in a timely fashion and
the content being loaded is loaded first.
Identically to what we've added to the module generators, let's raise a
coding exception if generating a block or a repository triggers the
theme and output initialisation.
