+=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.

-=head1 INTRODUCTION
+=head1 OVERVIEW
-This module provides subroutines which interact with the
-lonc/lond (TCP) network layer of LON-CAPA. And Can be used to ask about
-- classes
-- users
-- resources
+lonnet provides subroutines which interact with the
+lonc/lond (TCP) network layer of LON-CAPA. They can be used to ask
+about classes, users, and resources.
For many of these objects you can also use this to store data about
them or modify them in various ways.
-This is part of the LearningOnline Network with CAPA project
-described at http://www.lon-capa.org.
+=head2 Symbs
-=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
-when the connection is brought back up
+Symbs are used by the random number generator, as well as to store and
+restore data specific to a certain instance of for example a problem.
-=item *
+=head2 Storing And Retrieving Data
-con_failed : unable to contact remote host and unable to save message
-for later delivery
+X<store()>X<cstore()>X<restore()>Three of the most important functions
+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:
+
+ %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);
