NAME

6       Apache::Session::Browseable::Postgres - Add index and search methods to
7       Apache::Session::Postgres
8

SYNOPSIS

10       Create table with columns for indexed fields. Example for
11       Lemonldap::NG:
12
13         CREATE UNLOGGED TABLE sessions (
14             id varchar(64) not null primary key,
15             a_session text,
16             _whatToTrace text,
17             _session_kind text,
18             _utime bigint,
19             ipAddr varchar(64)
20         );
21
22       Add indexes:
23
24         CREATE INDEX uid1 ON sessions USING BTREE (_whatToTrace);
25         CREATE INDEX s1   ON sessions (_session_kind);
26         CREATE INDEX u1   ON sessions (_utime);
27         CREATE INDEX ip1  ON sessions USING BTREE (ipAddr);
28
29       Use it with Perl:
30
31         use Apache::Session::Browseable::Postgres;
32
33         my $args = {
34              DataSource => 'dbi:Pg:sessions',
35              UserName   => $db_user,
36              Password   => $db_pass,
37              Commit     => 1,
38
39              # Choose your browseable fileds
40              Index      => '_whatToTrace _session_kind _utime iAddr',
41         };
42
43         # Use it like Apache::Session
44         my %session;
45         tie %session, 'Apache::Session::Browseable::Postgres', $id, $args;
46         $session{uid} = 'me';
47         $session{mail} = 'me@me.com';
48         $session{unindexedField} = 'zz';
49         untie %session;
50
51         # Apache::Session::Browseable add some global class methods
52         #
53         # 1) search on a field (indexed or not)
54         my $hash = Apache::Session::Browseable::Postgres->searchOn( $args, 'uid', 'me' );
55         foreach my $id (keys %$hash) {
56           print $id . ":" . $hash->{$id}->{mail} . "\n";
57         }
58
59         # 2) Parse all sessions
60         # a. get all sessions
61         my $hash = Apache::Session::Browseable::Postgres->get_key_from_all_sessions();
62
63         # b. get some fields from all sessions
64         my $hash = Apache::Session::Browseable::Postgres->get_key_from_all_sessions('uid', 'mail')
65
66         # c. execute something with datas from each session :
67         #    Example : get uid and mail if mail domain is
68         my $hash = Apache::Session::Browseable::Postgres->get_key_from_all_sessions(
69                     sub {
70                        my ( $session, $id ) = @_;
71                        if ( $session->{mail} =~ /mydomain.com$/ ) {
72                            return { $session->{uid}, $session->{mail} };
73                        }
74                     }
75         );
76         foreach my $id (keys %$hash) {
77           print $id . ":" . $hash->{$id}->{uid} . "=>" . $hash->{$id}->{mail} . "\n";
78         }

DESCRIPTION

81       Apache::Session::Browseable provides some class methods to manipulate
82       all sessions and add the capability to index some fields to make
83       research faster.
84
85       Apache::Session::Browseable::Postgres implements it for PosqtgreSQL
86       databases.
