The requesting user is not always the same as the current user. The container class now allows a different user
to be set as the requesting user. All capability checks are done against the requesting user.
Also, the $requestinguser is passed to core_calendar_provide_event_action and core_calendar_is_event_visible
callback functions. These callback functions need to be updated in all activity modules to accept a $user parameter.
Fixes a typo in the function that replaces the LTI placeholder variable
LtiLink.memberships.url with the actual endpoint. Without this change,
the placeholder variable, "$LtiLink.memberships.url" is not replaced in
the LTI launch parameters.
Before this change if only a folder was submitted the submission_is_empty
check would return true. This meant that the draft area would be saved.
The is_empty check would then be called which would return false. This
caused the submission form to indicate to the user that the submission
had failed.
Now is_empty and submission_is_empty should both return false if only
folders are submitted.
The regexes to detect the optional prefixes at the start of some
interaction types are constructed to optionally match the prefix, so we
need to ensure that the matched group is really there when trying to
strip it from the given value in CRCheckValueNodes.
also remove "check for prefix" from CRcheckValueNodes
prefixes on correct responses patterns are removed in the section above
by CRremovePrefixes, so this block was redundant.
The `.pre` property for each correct_response is not used anywhere
else, so this removes their definitions too.
The check determining whether a choice option's limit was exceeded was
including the user's existing answers in its checks, meaning a user
couldn't save an existing choice answer, or select further options,
if all a choice option limit was reached. This patch fixes that.
The help string for the download as folders setting should not mention the number of files
submitted by the student. It is not related to that, it is only dependant on the value of this setting.
