them or modify them in various ways. |
| |
|
| 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. |
| |

=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(); |
| |
|
| no_such_host : unable to fund a host associated with the user/domain |
#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); |

Access data is also aggregated for each file in an additional key=value pair: |
| |
key -> path to file/file_name\0accesscontrol |
| |
value -> reference to hash |
| |
hash contains key = value pairs |
| |
where key = uniqueID:scope_end_start |
