=head1 NAME |
| |
|
| |
Apache::lonnet.pm |
| |
|
| |
=head1 SYNOPSIS |
| |
|
| |
This file is an interface to the lonc processes of |
| |
the LON-CAPA network as well as set of elaborated functions for handling information |
| |
necessary for navigating through a given cluster of LON-CAPA machines within a |
| |
domain. There are over 40 specialized functions in this module which handle the |
| |
reading and transmission of metadata, user information (ids, names, environments, roles, |
| |
logs), file information (storage, reading, directories, extensions, replication, embedded |
| |
styles and descriptors), educational resources (course descriptions, section names and |
| |
numbers), url hashing (to assign roles on a url basis), and translating abbreviated symbols to |
| |
and from more descriptive phrases or explanations. |
| |
|
| |
This is part of the LearningOnline Network with CAPA project |
| |
described at http://www.lon-capa.org. |
| |

=head1 Package Variables |
| |
|
| |
These are largely undocumented, so if you decipher one please note it here. |
| |
|
| |
=over 4 |
| |
|
| |
=item $processmarker |
| |
|
| |
Contains the time this process was started and this servers host id. |
| |
|
| |
=item $dumpcount |
| |
|
| |
Counts the number of times a message log flush has been attempted (regardless |
| |
of success) by this process. Used as part of the filename when messages are |
| |
delayed. |

| |
# Inputs: |

# |
| |
# $is_home - true if current server is home server for user's space |

# $context - either: priv, or res respectively for Authoring or Resource Space. |

| |
# Purpose: |
| |
# Return resource data for either users or for a course. |
| |
# Parameters: |
| |
# $name - Course/user name. |
| |
# $domain - Name of the domain the user/course is registered on. |
| |
# $type - Type of thing $name is (must be 'course' or 'user') |
| |
# $mapp - decluttered URL of enclosing map |
| |
# $recursed - Ref to scalar -- set to 1, if nested maps have been recursed. |
| |
# $recurseup - Ref to array of map URLs, starting with map containing |
| |
# $mapp up through hierarchy of nested maps to top level map. |
| |
# $courseid - CourseID (first part of param identifier). |
| |
# $modifier - Middle part of param identifier. |
| |
# $what - Last part of param identifier. |
| |
# @which - Array of names of resources desired. |
| |
# Returns: |
| |
# The value of the first reasource in @which that is found in the |
| |
# resource hash. |
| |
# Exceptional Conditions: |
| |
# If the $type passed in is not valid (not the string 'course' or |
| |
# 'user', an undefined reference is returned. |
| |
# If none of the resources are found, an undef is returned |

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(); |
| |
|
| |
#print the hash |
| |
foreach my $key (sort(keys(%history))) { |
| |
print("\%history{$key} = $history{$key}"); |
| |
} |
| |
|
| |
Will print out: |
| |
|
| no_such_host : unable to fund a host associated with the user/domain |
%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); |
| |
&Apache::lonnet::cstore(\%newrecord,$symb,$courseid,$domain,$uname,$laststore); |
| |
|
| |

$username:$domain is a privileged user (e.g., Domain Coordinator or Super User) |

$possdomains and $possroles are optional array refs -- to domains to check and |
| |
roles to check. If $possdomains is not specified, a dump will be done of the |
| |
users' roles.db to check for a dc or su role in any domain. This can be |
| |
time consuming if &privileged is called repeatedly (e.g., when displaying a |
| |
classlist), so in such cases, supplying a $possdomains array is preferred, as |
| |
this then allows &privileged_by_domain() to be used, which caches the identity |
| |
of privileged users, eliminating the need for repeated calls to &dump(). |

repeated dumps of domain roles -- via &get_domain_roles() -- contents of the |

get_timebased_id(): |
| |
|
| |
Attempts to get a unique timestamp-based suffix for use with items added to a |

group bulletin boards). |

|
| |
Args: (first three required; six others optional) |
| |

2. keyid (alphanumeric): name of temporary locking key in hash, |
| |
e.g., num, boardids |

| |
|
| |
7. who: holder of locking key; defaults to user:domain for user. |
