NAME

Apache::Session::Browseable::MySQL - Add index and search methods to Apache::Session::MySQL

SYNOPSIS

Create table with columns for indexed fields. Example for Lemonldap::NG:

CREATE TABLE sessions (
    id varchar(64) not null primary key,
    a_session text,
    _whatToTrace text,
    _session_kind text,
    _utime bigint,
    ipAddr text
);

Add indexes:

CREATE INDEX uid1 ON sessions (_whatToTrace) USING BTREE;
CREATE INDEX s1   ON sessions (_session_kind);
CREATE INDEX u1   ON sessions (_utime);
CREATE INDEX ip1  ON sessions (ipAddr) USING BTREE;

Use it with Perl:

use Apache::Session::Browseable::MySQL;

my $args = {
     DataSource => 'dbi:mysql:sessions',
     UserName   => $db_user,
     Password   => $db_pass,
     LockDataSource => 'dbi:mysql:sessions',
     LockUserName   => $db_user,
     LockPassword   => $db_pass,

     # Choose your browseable fileds
     Index          => 'uid mail',
};

# Use it like Apache::Session
my %session;
tie %session, 'Apache::Session::Browseable::MySQL', $id, $args;
$session{uid} = 'me';
$session{mail} = 'me@me.com';
$session{unindexedField} = 'zz';
untie %session;

# Apache::Session::Browseable add some global class methods
#
# 1) search on a field (indexed or not)
my $hash = Apache::Session::Browseable::MySQL->searchOn( $args, 'uid', 'me' );
foreach my $id (keys %$hash) {
  print $id . ":" . $hash->{$id}->{mail} . "\n";
}

# 2) Parse all sessions
# a. get all sessions
my $hash = Apache::Session::Browseable::MySQL->get_key_from_all_sessions();

# b. get some fields from all sessions
my $hash = Apache::Session::Browseable::MySQL->get_key_from_all_sessions('uid', 'mail')

# c. execute something with datas from each session :
#    Example : get uid and mail if mail domain is
my $hash = Apache::Session::Browseable::MySQL->get_key_from_all_sessions(
            sub {
               my ( $session, $id ) = @_;
               if ( $session->{mail} =~ /mydomain.com$/ ) {
                   return { $session->{uid}, $session->{mail} };
               }
            }
);
foreach my $id (keys %$hash) {
  print $id . ":" . $hash->{$id}->{uid} . "=>" . $hash->{$id}->{mail} . "\n";
}

DESCRIPTION
