=head1 NAME
DBIx::Password - Allows you to create a global password file for DB passwords
=head1 SYNOPSIS
use DBIx::Password;
my $dbh = DBIx::Password->connect($user);
my $dbh = DBIx::Password->connect_cached($user);
$dbh->getDriver;
DBIx::Password::getDriver($user);
DBIx::Password::checkVirtualUser($user);
DBIx::Password::clearConfig();
DBIx::Password::readConfig("$ENV{HOME}/.my.secret.file");
=head1 DESCRIPTION
Don't you hate keeping track of database passwords and such throughout
your scripts? How about the problem of changing those passwords
on a mass scale? This module is one possible solution. It stores all your
virtual users and data in /etc/dbix-password.conf.
For each user you need to specify the database module to use,
the database connect string, the username and the password.
You will have to give a name to this virtual user.
You can add as many as you like.
I would recommend that if you are only using this with
web applications that you change the final permissions on this
package after it is installed in site_perl such that only
the webserver can read it.
A method called getDriver has been added so that you
can determine what driver is being used (handy for
working out database indepence issues).
If you want to find out if the virtual user is valid,
you can call the class method checkVirtualUser().
It returns true (1) if the username is valid, and
zero if not.
Once your are done you can use the connect method (or
the connect_cache method) that comes with DBIx-Password
and just specify one of the virtual users you defined
while making the module.
BTW I learned the bless hack that is used from Apache::DBI
so some credit should go to the authors of that module.
This is a rewrite of the module Tangent::DB that I did
for slashcode.
If your program does not need the system-wide information stored
in the /etc/dbix-password.conf file, you may use the clearConfig()
and readConfig() functions to get the data from another source.
At any time, readConfig() may also be used to merge the data from
another file into the currently-loaded configuration.
Hope you enjoy it.
