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.

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 13716: =head1 OVERVIEW
1.191 harris41 13717:
1.394 bowersj2 13718: lonnet provides subroutines which interact with the
13719: lonc/lond (TCP) network layer of LON-CAPA. They can be used to ask
13720: about classes, users, and resources.
1.243 albertel 13721:
13722: For many of these objects you can also use this to store data about
13723: them or modify them in various ways.
1.191 harris41 13724:
1.394 bowersj2 13725: =head2 Symbs
1.191 harris41 13726:
1.394 bowersj2 13727: To identify a specific instance of a resource, LON-CAPA uses symbols
13728: or "symbs"X<symb>. These identifiers are built from the URL of the
13729: map, the resource number of the resource in the map, and the URL of
13730: the resource itself. The latter is somewhat redundant, but might help
13731: if maps change.
13732:
13733: An example is
13734:
13735: msu/korte/parts/part1.sequence___19___msu/korte/tests/part12.problem
13736:
13737: The respective map entry is
13738:
13739: <resource id="19" src="/res/msu/korte/tests/part12.problem"
13740: title="Problem 2">
13741: </resource>
13742:
13743: Symbs are used by the random number generator, as well as to store and
13744: restore data specific to a certain instance of for example a problem.
13745:
13746: =head2 Storing And Retrieving Data
13747:
13748: X<store()>X<cstore()>X<restore()>Three of the most important functions
13749: in C<lonnet.pm> are C<&Apache::lonnet::cstore()>,
13750: C<&Apache::lonnet:restore()>, and C<&Apache::lonnet::store()>, which
13751: is is the non-critical message twin of cstore. These functions are for
13752: handlers to store a perl hash to a user's permanent data space in an
13753: easy manner, and to retrieve it again on another call. It is expected
13754: that a handler would use this once at the beginning to retrieve data,
13755: and then again once at the end to send only the new data back.
13756:
13757: The data is stored in the user's data directory on the user's
13758: homeserver under the ID of the course.
13759:
13760: The hash that is returned by restore will have all of the previous
13761: value for all of the elements of the hash.
13762:
13763: Example:
13764:
13765: #creating a hash
13766: my %hash;
13767: $hash{'foo'}='bar';
13768:
13769: #storing it
13770: &Apache::lonnet::cstore(\%hash);
13771:
13772: #changing a value
13773: $hash{'foo'}='notbar';
13774:
13775: #adding a new value
13776: $hash{'bar'}='foo';
13777: &Apache::lonnet::cstore(\%hash);
13778:
13779: #retrieving the hash
13780: my %history=&Apache::lonnet::restore();
13781:
13782: #print the hash
13783: foreach my $key (sort(keys(%history))) {
13784: print("\%history{$key} = $history{$key}");
13785: }
13786:
13787: Will print out:
1.191 harris41 13788:
1.394 bowersj2 13789: %history{1:foo} = bar
13790: %history{1:keys} = foo:timestamp
13791: %history{1:timestamp} = 990455579
13792: %history{2:bar} = foo
13793: %history{2:foo} = notbar
13794: %history{2:keys} = foo:bar:timestamp
13795: %history{2:timestamp} = 990455580
13796: %history{bar} = foo
13797: %history{foo} = notbar
13798: %history{timestamp} = 990455580
13799: %history{version} = 2
13800:
13801: Note that the special hash entries C<keys>, C<version> and
13802: C<timestamp> were added to the hash. C<version> will be equal to the
13803: total number of versions of the data that have been stored. The
13804: C<timestamp> attribute will be the UNIX time the hash was
13805: stored. C<keys> is available in every historical section to list which
13806: keys were added or changed at a specific historical revision of a
13807: hash.
13808:
13809: B<Warning>: do not store the hash that restore returns directly. This
13810: will cause a mess since it will restore the historical keys as if the
13811: were new keys. I.E. 1:foo will become 1:1:foo etc.
