NAME¶

Data::Session::ID::UUID16 - A persistent session manager

Synopsis¶

See Data::Session for details.

Case-sensitive Options¶

See "Case-sensitive Options" in Data::Session for important information.

To use this module do this:

o Specify an id generator of type UUID16, as Data::Session -> new(type => '... id:UUID16 ...')

Description¶

Data::Session::ID::UUID16 allows Data::Session to generate session ids using Data::UUID.

Method: new()¶

Creates a new object of type Data::Session::ID::UUID16.

"new()" takes a hash of key/value pairs, some of which might mandatory. Further, some combinations might be mandatory.

The keys are listed here in alphabetical order.

They are lower-case because they are (also) method names, meaning they can be called to set or get the value at any time.

o verbose => $integer

Print to STDERR more or less information.

Typical values are 0, 1 and 2.

This key is normally passed in as Data::Session -> new(verbose => $integer).

This key is optional.

Method: generate()¶

Generates the next session id, or dies if it can't.

The algorithm is Data::UUID -> new -> create_bin.

Returns the new id.

Note: A UUID16 hex string is not necessarily a valid UTF8 string, so you can't use UUID16 to generate ids which are to be stored in a Postgres table if the database was created like this (in psql):

        create database a_db owner an_owner encoding 'UTF8';

Warning: This also means you should never try to use 'driver:File;id:UUID16;...', since the ids generated by this module would rarely if ever be valid as a part of a file name.

Method: id_length()¶

Returns 16 because that's the number of bytes in a UUID16 digest.

This can be used to generate the SQL to create the sessions table.

See scripts/digest.pl.
