36: =head1 SYNOPSIS
37:
38: This file is an interface to the lonc processes of
39: the LON-CAPA network as well as set of elaborated functions for handling information
40: necessary for navigating through a given cluster of LON-CAPA machines within a
41: domain. There are over 40 specialized functions in this module which handle the
42: reading and transmission of metadata, user information (ids, names, environments, roles,
43: logs), file information (storage, reading, directories, extensions, replication, embedded
44: styles and descriptors), educational resources (course descriptions, section names and
45: numbers), url hashing (to assign roles on a url basis), and translating abbreviated symbols to
46: and from more descriptive phrases or explanations.
47:
48: This is part of the LearningOnline Network with CAPA project
49: described at http://www.lon-capa.org.

56:
57: =item $processmarker
58:
59: Contains the time this process was started and this servers host id.
60:
61: =item $dumpcount
62:
63: Counts the number of times a message log flush has been attempted (regardless
64: of success) by this process. Used as part of the filename when messages are
65: delayed.

1.394 bowersj2 15758: =head1 OVERVIEW
1.191 harris41 15759:
1.394 bowersj2 15760: lonnet provides subroutines which interact with the
15761: lonc/lond (TCP) network layer of LON-CAPA. They can be used to ask
15762: about classes, users, and resources.
1.243 albertel 15763:
15764: For many of these objects you can also use this to store data about
15765: them or modify them in various ways.
1.191 harris41 15766:
1.394 bowersj2 15767: =head2 Symbs
1.191 harris41 15768:
1.394 bowersj2 15769: To identify a specific instance of a resource, LON-CAPA uses symbols
15770: or "symbs"X<symb>. These identifiers are built from the URL of the
15771: map, the resource number of the resource in the map, and the URL of
15772: the resource itself. The latter is somewhat redundant, but might help
15773: if maps change.
15774:
15775: An example is
15776:
15777: msu/korte/parts/part1.sequence___19___msu/korte/tests/part12.problem
15778:
15779: The respective map entry is
15780:
15781: <resource id="19" src="/res/msu/korte/tests/part12.problem"
15782: title="Problem 2">
15783: </resource>
15784:
15785: Symbs are used by the random number generator, as well as to store and
15786: restore data specific to a certain instance of for example a problem.
15787:
15788: =head2 Storing And Retrieving Data
15789:
15790: X<store()>X<cstore()>X<restore()>Three of the most important functions
15791: in C<lonnet.pm> are C<&Apache::lonnet::cstore()>,
15792: C<&Apache::lonnet:restore()>, and C<&Apache::lonnet::store()>, which
15793: is is the non-critical message twin of cstore. These functions are for
15794: handlers to store a perl hash to a user's permanent data space in an
15795: easy manner, and to retrieve it again on another call. It is expected
15796: that a handler would use this once at the beginning to retrieve data,
15797: and then again once at the end to send only the new data back.
15798:
15799: The data is stored in the user's data directory on the user's
15800: homeserver under the ID of the course.
15801:
15802: The hash that is returned by restore will have all of the previous
15803: value for all of the elements of the hash.
15804:
15805: Example:
15806:
15807: #creating a hash
15808: my %hash;
15809: $hash{'foo'}='bar';
15810:
15811: #storing it
15812: &Apache::lonnet::cstore(\%hash);
15813:
15814: #changing a value
15815: $hash{'foo'}='notbar';
15816:
15817: #adding a new value
15818: $hash{'bar'}='foo';
15819: &Apache::lonnet::cstore(\%hash);
15820:
15821: #retrieving the hash
15822: my %history=&Apache::lonnet::restore();
15823:
15824: #print the hash
15825: foreach my $key (sort(keys(%history))) {
15826: print("\%history{$key} = $history{$key}");
15827: }
15828:
15829: Will print out:
1.191 harris41 15830:
1.394 bowersj2 15831: %history{1:foo} = bar
15832: %history{1:keys} = foo:timestamp
15833: %history{1:timestamp} = 990455579
15834: %history{2:bar} = foo
15835: %history{2:foo} = notbar
15836: %history{2:keys} = foo:bar:timestamp
15837: %history{2:timestamp} = 990455580
15838: %history{bar} = foo
15839: %history{foo} = notbar
15840: %history{timestamp} = 990455580
15841: %history{version} = 2
15842:
15843: Note that the special hash entries C<keys>, C<version> and
15844: C<timestamp> were added to the hash. C<version> will be equal to the
15845: total number of versions of the data that have been stored. The
15846: C<timestamp> attribute will be the UNIX time the hash was
15847: stored. C<keys> is available in every historical section to list which
15848: keys were added or changed at a specific historical revision of a
15849: hash.
15850:
15851: B<Warning>: do not store the hash that restore returns directly. This
15852: will cause a mess since it will restore the historical keys as if the
15853: were new keys. I.E. 1:foo will become 1:1:foo etc.
