Persistent::mSQL is a persistent class implemented using a mSQL database.

SYNOPSIS

use Persistent::mSQL;
use English; # import readable variable names like $EVAL_ERROR

eval { ### in case an exception is thrown ###

### allocate a persistent object ###
my $emp = new Persistent::mSQL($data_source, undef, undef, $table);

### define attributes of the object ###
$emp->add_attribute(empno, ID, Number, undef, 4);
$emp->add_attribute(ename, Persistent, VarChar, undef, 10);
$emp->add_attribute(job, Persistent, VarChar, undef, 9);
$emp->add_attribute(mgr, Persistent, Number, undef, 4);
$emp->add_attribute(hiredate, Persistent, DateTime, undef);
$emp->add_attribute(sal, Persistent, Number, undef, 7, 2);
$emp->add_attribute(comm, Persistent, Number, undef, 7, 2);
$emp->add_attribute(deptno, Persistent, Number, undef, 2);

### query the datastore for some objects ###
$emp->restore_where(qq{
sal > 1000 and
job = CLERK and
ename LIKE M%
}, "sal, ename");
while ($emp->restore_next()) {
printf "ename = %s, emp# = %s, sal = %s, hiredate = %sn",
$emp->ename, $emp->empno, $emp->sal, $emp->hiredate;
}
};

if ($EVAL_ERROR) { ### catch those exceptions! ###
print "An error occurred: $EVAL_ERRORn";
}

ABSTRACT

This is a Persistent class that uses a mSQL database table to store and retrieve objects. This class can be instantiated directly or subclassed. The methods described below are unique to this class, and all other methods that are provided by this class are documented in the Persistent documentation. The Persistent documentation has a very thorough introduction to using the Persistent framework of classes.

Persistent::Base is an Abstract Persistent Base Class.

SYNOPSIS

### we are a subclass of ... ###
use Persistent::Base;
@ISA = qw(Persistent::Base);

ABSTRACT

This is an abstract class used by the Persistent framework of classes to implement persistence with various types of data stores. This class provides the methods and interface for implementing Persistent classes. Refer to the Persistent documentation for a very thorough introduction to using the Persistent framework of classes.

This class is part of the Persistent base package which is available from:

http://www.bigsnow.org/persistent
ftp://ftp.bigsnow.org/pub/persistent

Before we get started describing the methods in detail, it should be noted that all error handling in this class is done with exceptions. So you should wrap an eval block around all of your code. Please see the Persistent documentation for more information on exception handling in Perl.

ABSTRACT METHODS THAT NEED TO BE OVERRIDDEN IN THE SUBCLASS

datastore -- Sets/Returns the Data Store Parameters

eval {
### set the data store ###
$person->datastore(@args);

### get the data store ###
$href = $person->datastore();
};
croak "Exception caught: $@" if $@;

Returns (and optionally sets) the data store of the object. This method throws Perl execeptions so use it with an eval block.

Setting the data store can involve anything from initializing a connection to opening a file. Getting a data store usually means returning information pertaining to the data store in a useful form, such as a connection to a database or a location of a file.

Persistent::Sybase is a persistent class implemented using a Sybase database.

SYNOPSIS

use Persistent::Sybase;
use English; # import readable variable names like $EVAL_ERROR

eval { ### in case an exception is thrown ###

### allocate a persistent object ###
my $emp = new Persistent::Sybase($data_source, $username, $password, $table);

### define attributes of the object ###
$emp->add_attribute(empno, ID, Number, undef, 4);
$emp->add_attribute(ename, Persistent, VarChar, undef, 10);
$emp->add_attribute(job, Persistent, VarChar, undef, 9);
$emp->add_attribute(mgr, Persistent, Number, undef, 4);
$emp->add_attribute(hiredate, Persistent, DateTime, undef);
$emp->add_attribute(sal, Persistent, Number, undef, 7, 2);
$emp->add_attribute(comm, Persistent, Number, undef, 7, 2);
$emp->add_attribute(deptno, Persistent, Number, undef, 2);

### query the datastore for some objects ###
$emp->restore_where(qq{
sal > 1000 and
job = CLERK and
ename LIKE M%
}, "sal, ename");
while ($emp->restore_next()) {
printf "ename = %s, emp# = %s, sal = %s, hiredate = %sn",
$emp->ename, $emp->empno, $emp->sal, $emp->hiredate;
}
};

if ($EVAL_ERROR) { ### catch those exceptions! ###
print "An error occurred: $EVAL_ERRORn";
}

Basset::Object::Persistent is a subclass of Basset::Object that allows objects to be easily stored into a relational database. Presently only supports MySQL, but that may change in the future.

SYNOPSIS

(no synopsis, this is an abstract super class that should never be instantiated directly, it should be subclassed for all persistent objects and used through them)

Basset::Object is the uber module in my Perl world. All objects should decend from Basset::Object. It handles defining attributes, error handling, construction, destruction, and generic initialization. It also talks to Basset::Object::Conf to allow conf file use.
But, some objects cannot simply be recreated constantly every time a script runs. Sometimes you need to store the data in an object between uses so that you can recreate an object in the same form the last time you left it. Storing user information, for instance.

Basset::Object::Persistent allows you to do that transparently and easily. Persistent objects need to define several pieces of additional information to allow them to commit to the database, including their table definitions. Once these items are defined, youll have access to the load and commit methods to allow you to load and store the objects in a database.

It is assumed that an object is stored in the database in a primary table. The primary table contains a set of columns named the same as object attributes. The attributes are stored in those columns.

Some::Package->add_attr(foo);
my $obj = Some::Package->new();
$obj->foo(bar);
$obj->commit();

in the database, the foo column will be set to bar.

poker-network project includes a poker server, a client library, an abstract user interface library, and a client based on it.

The server deals the cards and checks the user actions using a poker game engine (poker-engine). It listens on a TCP/IP port and understands its own specific protocol. The persistent information is stored in a MySQL database.

The client library implements the poker-network protocol for the client. The abstract user interface library provides a framework based on the client library and suited to implement a user friendly client.

VoiceBuntu (Ubunterisk) is an Ubuntu based live Linux distribution that uses Asterisk and VoiceOne to provide VoIP service.
VoiceBuntus focus is to run asterisk with no installation needed. VoiceBuntu - ubuntu itself - has built in boot prompt cheap code one can use called persistent.
This feature allows the user to use VoiceBuntus persistent feature in order to keep settings on a flash disk or memory stick.
To start, just burn the ISO file on a CD-ROM then start the live cd distribution and wait until everything is ready.
Please note, that apache will start at the very last moment of the boot cycle. So you may a to wait 1 or 2 minutes to let everything load.
Once everything is prepared, start your browser and point to the IP address of your running VoiceBuntu (i.e. http://192.168.0.10).
If you have no DHCP Server available you can press F6 at boot screen and add additionally add the command parameter
static=xxx.xxx.xxx.xxx
netmask=xxx.xxx.xxx.xxx
bcast=xxx.xxx.xxx.xxx
gateway=xxx.xxx.xxx.xxx
dns1=xxx.xxx.xxx.xxx
dns2=xxx.xxx.xxx.xxx
where xxx.xxx.xxx.xxx is the IP of your choice.
By that VoiceBuntu boots with static IP address on eth0 network device.
Enhancements:
- This live CD release is based on Ubuntu 7.04 and VoiceOne 0.5.0_2 due to a minor bug in VoiceOne version 0.5.0.

Twisted Web includes an HTTP/1.0 protocol implementation for both servers and clients. Twisted Web also includes a resource framework for implementing rich, dynamic web applications. It includes support for authentication either via HTTP AUTH, session URLs, or session cookies.
It supports CGIs and a custom PB-based distribution mechanism for serving content from separate, persistent processes. It includes SOAP and XML-RPC support for both clients and servers. It also makes it particularly easy to deploy new servers with novel or ephemeral use-cases, often with only a single short command.
Enhancements:
- This release adds HTTP Basic auth support for XML-RPC clients, and fixes several date, time, and If-Modified-Since header parsing corner-cases.
- Various performance improvements have been made, and support for CGIs broken in a few specific ways has been improved.
