VERSION

version 1.236

SYNOPSIS

use Config::Model ;
use Log::Log4perl qw(:easy) ;
use Data::Dumper ;

Log::Log4perl->easy_init($WARN);

# define configuration tree object
my $model = Config::Model->new ;
$model ->create_config_class (
   name => "MyClass",
   element => [ 
       Depends => {
           'type'       => 'leaf',
           'value_type' => 'uniline',
           class => 'Config::Model::Debian::Dependency',
       },
   ],
) ;

my $inst = $model->instance(root_class_name => 'MyClass' );

my $root = $inst->config_root ;

$root->load( 'Depends="libc6 ( >= 1.0 )"') ;
# Connecting to qa.debian.org to check libc6 versions. Please wait ...
# Warning in 'Depends' value 'libc6 ( >= 1.0 )': unnecessary
# versioned dependency: >= 1.0. Debian has lenny-security ->
# 2.7-18lenny6; lenny -> 2.7-18lenny7; squeeze-security ->
# 2.11.2-6+squeeze1; squeeze -> 2.11.2-10; wheezy -> 2.11.2-10; sid
# -> 2.11.2-10; sid -> 2.11.2-11;

DESCRIPTION

This class is derived from Config::Model::Value. Its purpose is to check the value of a Debian package dependency for the following:

• syntax as described in http://www.debian.org/doc/debian-policy/ch-relationships.html

• Whether the version specified with > or >= is necessary. This module will check with Debian server whether older versions can be found in Debian old-stable or not. If no older version can be found, a warning will be issued.

Cache

Queries to Debian server are cached in ~/.config_model_depend_cache for about one month.

BUGS

More advanced checks can probably be implemented. The author is open to new ideas. He's even more open to patches (with tests).
