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

Apache::Session::browseable provides some class methods to manipulate all sessions and add the capability to index some fields to make research faster.
