The core_group_get_activity_allowed_groups WS should be returning not
only the groups but also if the user is allowed to access all the
activity groups.
In the issue MDL-39319 (6ddf92c77), the ability to uninstall multiple
language packs at once was added. By a mistake, the PARAM_ALPHAEXT was
used as paramater type for the dash-separated list of language packs to
be uninstalled. Language packs with a number in the name (such as
en_us_k12) do not pass the ALPHAEXT cleaning.
This patch changes the parameter cleaning to PARAM_SAFEPATH which is
more appropriate for the given scenario as language code themselves must
be SAFEDIRs.
Default of $params = null leads to a problem in query_db().
There this value is used in array_merge, which can not handle null
values. If null is passed for one of the params the outcome will be null
independent of the value of the second param!
Repository instances are stored in the 'repository' table. Repositories
in the table are either 'Enabled and visible' or 'Enabled but hidden'.
Hidden repositories still serve their files, but are not visible in the
filepicker UI. Disabling a repository instance removes its record from
the table.
In the original implementation of the plugin manager (see b9934a17), the
method plugintype_repository::get_enabled_repositories() correctly
returned all records from the repository table. Then as a part of the
bigger refactoring in MDL-41437, the commit bde002b8 replaced the
original method with the new get_enabled_plugins() one which started to
return visible repositories only.
As a consequence, the admin tree stopped populating setting page nodes
for hidden repository instances. So attempting to visit their setting
page threw a section error. Credit goes to Ike Quigley for debugging and
tracing this down.
This patch fixes the way how the list of enabled repositories is
populated by the plugin manager so that both visible and hidden
repositories are returned again. This does not affect the filepicker
itself as it is using its own methods for obtaining the list.
There can be a different number of courses displayed in the
'Navigation' block and in the 'Flat' navigation. This patch
decides what courses we want to display on each, then
applies the 'navcourselimit' setting individually.
Find any events records for assign group overrides having null priority
and sets their priority to the sortorder value from the corresponding
assign_overrides table entry.
