|
|
This is part of the LearningOnline Network with CAPA project |
=head2 Symbs |
described at http://www.lon-capa.org. |
|
|
|
=head1 RETURN MESSAGES |
To identify a specific instance of a resource, LON-CAPA uses symbols |
|
or "symbs"X<symb>. These identifiers are built from the URL of the |
|
map, the resource number of the resource in the map, and the URL of |
|
the resource itself. The latter is somewhat redundant, but might help |
|
if maps change. |
|
|
=over 4 |
An example is |
|
|
=item * |
msu/korte/parts/part1.sequence___19___msu/korte/tests/part12.problem |
|
|
con_lost : unable to contact remote host |
The respective map entry is |
|
|
=item * |
<resource id="19" src="/res/msu/korte/tests/part12.problem" |
|
title="Problem 2"> |
|
</resource> |
|
|
con_delayed : unable to contact remote host, message will be delivered |
Symbs are used by the random number generator, as well as to store and |
when the connection is brought back up |
restore data specific to a certain instance of for example a problem. |
|
|
=item * |
=head2 Storing And Retrieving Data |
|
|
con_failed : unable to contact remote host and unable to save message |
X<store()>X<cstore()>X<restore()>Three of the most important functions |
for later delivery |
in C<lonnet.pm> are C<&Apache::lonnet::cstore()>, |
|
C<&Apache::lonnet:restore()>, and C<&Apache::lonnet::store()>, which |
|
is is the non-critical message twin of cstore. These functions are for |
|
handlers to store a perl hash to a user's permanent data space in an |
|
easy manner, and to retrieve it again on another call. It is expected |
|
that a handler would use this once at the beginning to retrieve data, |
|
and then again once at the end to send only the new data back. |
|
|
=item * |
The data is stored in the user's data directory on the user's |
|
homeserver under the ID of the course. |
|
|
error: : an error a occured, a description of the error follows the : |
The hash that is returned by restore will have all of the previous |
|
value for all of the elements of the hash. |
|
|
=item * |
Example: |
|
|
|
#creating a hash |
|
my %hash; |
|
$hash{'foo'}='bar'; |
|
|
|
#storing it |
|
&Apache::lonnet::cstore(\%hash); |
|
|
|
#changing a value |
|
$hash{'foo'}='notbar'; |
|
|
|
#adding a new value |
|
$hash{'bar'}='foo'; |
|
&Apache::lonnet::cstore(\%hash); |
|
|
|
#retrieving the hash |
|
my %history=&Apache::lonnet::restore(); |
|
|
|
#print the hash |
|
foreach my $key (sort(keys(%history))) { |
|
print("\%history{$key} = $history{$key}"); |
|
} |
|
|
|
Will print out: |
|
|
|
%history{1:foo} = bar |
|
%history{1:keys} = foo:timestamp |
|
%history{1:timestamp} = 990455579 |
|
%history{2:bar} = foo |
|
%history{2:foo} = notbar |
|
%history{2:keys} = foo:bar:timestamp |
|
%history{2:timestamp} = 990455580 |
|
%history{bar} = foo |
|
%history{foo} = notbar |
|
%history{timestamp} = 990455580 |
|
%history{version} = 2 |
|
|
|
Note that the special hash entries C<keys>, C<version> and |
|
C<timestamp> were added to the hash. C<version> will be equal to the |
|
total number of versions of the data that have been stored. The |
|
C<timestamp> attribute will be the UNIX time the hash was |
|
stored. C<keys> is available in every historical section to list which |
|
keys were added or changed at a specific historical revision of a |
|
hash. |
|
|
|
B<Warning>: do not store the hash that restore returns directly. This |
|
will cause a mess since it will restore the historical keys as if the |
|
were new keys. I.E. 1:foo will become 1:1:foo etc. |
|
|
|
Calling convention: |
|
|
|
my %record=&Apache::lonnet::restore($symb,$courseid,$domain,$uname,$home); |
|
&Apache::lonnet::cstore(\%newrecord,$symb,$courseid,$domain,$uname,$home); |
|
|
|

modifystudent |
|
|
|
modify a students enrollment and identification information. |
|
The course id is resolved based on the current users environment. |
|
This means the envoking user must be a course coordinator or otherwise |
|
associated with a course. |
|
|
|
This call is essentially a wrapper for lonnet::modifyuser and |
|
lonnet::modify_student_enrollment |

(a) files in /uploaded |
|
(i) If a local copy of the file exists - |
|
compares modification date of local copy with last-modified date for |
|
definitive version stored on home server for course. If local copy is |
|
stale, requests a new version from the home server and stores it. |
|
If the original has been removed from the home server, then local copy |
|
is unlinked. |
|
(ii) If local copy does not exist - |
|
requests the file from the home server and stores it. |
|
|
|
If $caller is 'uploadrep': |
|
This indicates a call from lonuploadrep.pm (PerlHeaderParserHandler phase) |
|
for request for files originally uploaded via DOCS. |
|
- returns 'ok' if fresh local copy now available, -1 otherwise. |
|
|
|
Otherwise: |
|
This indicates a call from the content generation phase of the request. |
|
- returns the entire contents of the file or -1. |
|
|
|
(b) files in /res |
|
- returns the entire contents of a file or -1; |
|
it properly subscribes to and replicates the file if neccessary. |
