HEAD
- Bug 6518
- Exam blocks can also block access to specified folders and/or resources
for the duration of an exam.
- Start time for blocking can be based on activation of the timer for
a specific timed quiz item (map or resource-specific). End time for
blocking is then start time plus the duration of the timed interval.
lonnet.pm:
- &rolesinit() now returns an array containing references to hashes
for the following: userroles, firstaccenv, timerintenv.
- New db file: timerinterval.db contains interval which applied when
user activated timer for a map or resource for which time limit applied.
- needed to determine end time for exam blocks which are triggered by
timer activation.
- New routine &get_comm_blocks() used to get communication/collaboration
blocks from a course. Now cached for 10 minutes in memcached.
- New routine: &has_comm_blocking() used to determine if exam block
applies to display of requested content item in a course. Used by
&allowed().
- new routine: &check_docs_block() used by &has_comm_blocking().
loncommon.pm:
- new items added to user's environment by &init_user_environment()
- $env{'course.courseid.firstaccess.symb'} and
$env{'course.courseid.timerinterval.symb'} where symb is the symb
of the resource or map which provides the activation-based block
for access to specific content.
blockedaccess.pm:
- now called when access to content is blocked by an exam block.
duration, and setter of block now available in pop-up from:
&loncommon::blocking_status() for this type of access control.
