=item releasereqd_check( $cnum, $cdom, $key, $value, $major, $minor, |
|
$homecourses, $ids ) |
|
|
|
releasereqd_check() will determine if a LON-CAPA version (defined in the |
|
$major,$minor args passed) is not too old to allow use of a role in a |
|
course ($cnum,$cdom args passed), if at least one of the following applies: |
|
(a) the course is a Community, (b) the course's home server is *not* the |
|
current server, or (c) cached course information is not stale. |
|
|
|
For the case where none of these apply, the course is added to the |
|
$homecourse hash ref (keys = courseIDs, values = array of a hash of roles). |
|
The $homecourse hash ref is for courses for which the current server is the |
|
home server. LON-CAPA version requirements are checked elsewhere for the |
|
items in $homecourse. |
|
|
|
|
|
=item check_homecourses( $homecourses, $regexp, $count, $range, $start, $end, |
|
$major, $minor ) |
|
|
|
check_homecourses() will retrieve course information for those courses which |
|
are keys of the $homecourses hash ref (first arg). The nohist_courseids.db |
|
GDBM file is tied and course information for each course retrieved. Last |
|
visit (lasttime key) is also retrieved for each, and cached values updated |
|
for any courses last visited less than 24 hours ago. Cached values are also |
|
updated for any courses included in the $homecourses hash ref. |
|
|
|
The reason for the 24 hours constraint is that the cron entry in |
|
/etc/cron.d/loncapa for /home/httpd/perl/refresh_courseids_db.pl causes |
|
cached course information to be updated nightly for courses with activity |
|
within the past 24 hours. |
|
|
|
Role information for the user (included in a ref to an array of hashes as the |
|
value for each key in $homecourses) is appended to the result returned by the |
|
routine, which will in turn be appended to the string returned to the client |
|
hosting the user's session. |
|
|
|
|
|
=item useable_role( $reqdmajor, $reqdminor, $major, $minor ) |
|
|
|
useable_role() will compare the LON-CAPA version required by a course with |
|
the version available on the client server. If the client server's version |
|
is compatible, 1 will be returned. |
|
|
|
|
|
=item get_courseinfo_hash( $cnum, $cdom, $home ) |
|
|
|
get_courseinfo_hash() is used to retrieve course information from the db |
|
file: nohist_courseids.db for a course for which the current server is *not* |
|
the home server. |
|
|
|
A hash of a hash will be retrieved. The outer hash contains a single key -- |
|
courseID -- for the course for which the data are being requested. |
|
The contents of the inner hash, for that single item in the outer hash |
|
are returned (and cached in memcache for 10 minutes). |
