NAME

Prancer::Session::Store::Database

SYNOPSIS

This module implements a session handler by storing sessions in a database. It uses a separate database connection from the main application to avoid any issues with transactions. It wraps all changes to the database in transactions to ensure consistency.

This configuration expects a database table that looks like this:

CREATE TABLE sessions (
    id CHAR(72) PRIMARY KEY,
    data TEXT,
    timeout integer DEFAULT date_part('epoch'::text, now()) NOT NULL
);

Additionally columns may be added as desired.

To use this session handler, add this to your configuration file:

session:
    store:
        driver: Prancer::Session::Store::Database::Driver::DriverName
        options:
            table: sessions
            database: test
            username: test
            password: test
            hostname: localhost
            port: 5432
            charset: utf8
            connection_check_threshold: 10
            expiration_timeout: 3600
            autopurge: 0

OPTIONS

table

The name of the table in your database to use to store sessions. This name may include a schema name. Otherwise the default schema of the user will be used. If this option is not provided the default will be sessions.

database

REQUIRED The name of the database to connect to.

username

The username to use when connecting. If this option is not set the default is the user running the application server.

password

The password to use when connectin. If this option is not set the default is to connect with no password.

hostname

The host name of the database server. If this option is not set the default is to connect to localhost.

port

The port number on which the database server is listening. If this option is not set the default is to connect on the database's default port.

charset

The character set to connect to the database with. If this is set to "utf8" then the database connection will attempt to make UTF8 data Just Work if available.

connection_check_threshold

This sets the number of seconds that must elapse between calls to get a database handle before performing a check to ensure that a database connection still exists and will reconnect if one does not. This handles cases where the database handle hasn't been used in a while and the underlying connection has gone away. If this is not set it will default to 30 seconds.

timeout

This the number of seconds a session should last in the database before it will be automatically purged. The default is to purge sessions after 1800 seconds.

autopurge

This flag controls whether sessions will be automatically purged by Prancer. If set to 1, the default, on 10% of requests to your application, Prancer will delete from the database any session that has timed out. If set to 0 then sessions will never be removed from the database. Note that this doesn't control whether sessions time out, only whether they get removed from the database.
