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.

55: =over 4
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 16721: =head1 OVERVIEW
1.191 harris41 16722:
1.394 bowersj2 16723: lonnet provides subroutines which interact with the
16724: lonc/lond (TCP) network layer of LON-CAPA. They can be used to ask
16725: about classes, users, and resources.
1.243 albertel 16726:
16727: For many of these objects you can also use this to store data about
16728: them or modify them in various ways.
1.191 harris41 16729:
1.394 bowersj2 16730: =head2 Symbs
1.191 harris41 16731:
1.394 bowersj2 16732: To identify a specific instance of a resource, LON-CAPA uses symbols
16733: or "symbs"X<symb>. These identifiers are built from the URL of the
16734: map, the resource number of the resource in the map, and the URL of
16735: the resource itself. The latter is somewhat redundant, but might help
16736: if maps change.
16737:
16738: An example is
16739:
16740: msu/korte/parts/part1.sequence___19___msu/korte/tests/part12.problem
16741:
16742: The respective map entry is
16743:
16744: <resource id="19" src="/res/msu/korte/tests/part12.problem"
16745: title="Problem 2">
16746: </resource>
16747:
16748: Symbs are used by the random number generator, as well as to store and
16749: restore data specific to a certain instance of for example a problem.
16750:
16751: =head2 Storing And Retrieving Data
16752:
16753: X<store()>X<cstore()>X<restore()>Three of the most important functions
16754: in C<lonnet.pm> are C<&Apache::lonnet::cstore()>,
16755: C<&Apache::lonnet:restore()>, and C<&Apache::lonnet::store()>, which
16756: is is the non-critical message twin of cstore. These functions are for
16757: handlers to store a perl hash to a user's permanent data space in an
16758: easy manner, and to retrieve it again on another call. It is expected
16759: that a handler would use this once at the beginning to retrieve data,
16760: and then again once at the end to send only the new data back.
16761:
16762: The data is stored in the user's data directory on the user's
