NAME
Lemonldap::Config::Parameters - Perl extension for lemonldap SSO system
SYNOPSIS
#!/usr/bin/perl
use strict;
use Lemonldap::Config::Parameters;
use Data::Dumper;
my $nconfig= Lemonldap::Config::Parameters->new(
file =>'applications.xml',
cache => 'CONF' );
my $conf= $nconfig->getAllConfig;
my $cg=$nconfig->getDomain('appli.cp');
my $ligne= $cg;
print Dumper( $ligne);
my $e = $cg->{templates_options} ;
my $opt= "templates_dir";
my $va = $cg->{$opt};
my $ligne= $nconfig->formateLineHash($e,$opt,$va) ;
or by API :
Lemonldap::Config::Parameters::f_delete('CONF');
or by command line
perl -e "use Lemonldap::Config::Parameters;Parameters::f_delete('CONF');"
DESCRIPTION
Lemonldap is a SSO system under GPL.
Login page , handlers must retrieve their configs in an unique file eg :"applications.xml" This file has a XML structrure . The parsing phase may be heavy . So lemonldap can cache the result of parsing in memory with IPC. For activing the cache you must have in the config :
<cache type="IPC" name="CONF" ttl="1000">
</cache>
with : name='CONF' it's the GLUE value : four letters (see IPC::Shareable documentation) .
ttl: time to live in second ( 0 for not reload )
if ttl is too short the config file will be reload very offen .
You can force the reload by command line
perl -e "use Lemonldap::Config::Parameters;Parameters::f_delete('CONF');"
or perl -e "use Lemonldap::Config::Parameters;Parameters::f_reload('CONF');"
WITHOUT CACHE SPECIFICATION , LEMONLDAP DOESN'T USE CACHE ! It will read and parse config file each time.
METHODS
new (file =>'/foo/my_xml_file.xml' , cache => 'CONF' ); # with IPC cache
or
new(file =>'/foo/my_xml_file.xml'); # without IPC cache
getAllConfig
Return the reference of hash storing whole the config.
getDomain('foo.bar')
Return the reference of hash of config for domain
If the config file has only one domain , domain may bo omit .
eg : for the xml config file : <domain name="foo.bar" cookie=".foo.bar" path ="/" templates_dir="/opt/apache/portail/templates" templates_options = "ABSOLUTE => '1', INCLUDE_PATH => 'templates_dir'" login ="http://cportail.foo.bar/portail/accueil.pl" menu= "http://cportail.foo.bar/portail/application.pl" ldap_server ="cpldap.foo.bar" ldap_port="389" DnManager= "cn=Directory Manager" passwordManager="secret" branch_people="ou=mefi,dc=foo,dc=bar" session="memcached" > </domain>
my $cg = $nconfig->getDomain();
DB<2> x $cg
0 HASH(0x89b108c)
'DnManager' => 'cn=Directory Manager'
'branch_people' => 'ou=mefi,dc=foo,dc=bar'
'cookie' => '.foo.bar'
'ldap_port' => 389
'ldap_server' => 'cpldap.foo.bar'
'login' => 'http://cportail.foo.bar/portail/accueil.pl'
'menu' => 'http://cportail.foo.bar/portail/application.pl'
'passwordManager' => 'secret'
'path' => '/'
'session' => 'memcached'
'templates_dir' => '/opt/apache/portail/templates'
'templates_options' => 'ABSOLUTE => \'1\', INCLUDE_PATH => \'templates_dir\'
ref_of_hash : formateLineHash(string:line);
or formateLineHash(string:line,string:motif,string:key);
Return a anonyme reference on hash and may replace the motif in the value of key by the value of another key :
eg
my $e = $cg->{templates_options} ;
my $opt= "templates_dir";
my $va = $cg->{$opt};
my $ligne= $nconfig->formateLineHash($e,$opt,$va) ;
gives :
DB<1> x $ligne
0 HASH(0x848b778)
'ABSOLUTE' => 1
'INCLUDE_PATH' => '/opt/apache/portail/templates'
$ligne can be use directly like option for somes instructions
ref_of_array : formateLineArray(string:line);
or formateLineArray(string:line,string:motif,string:key);
Return a anonyme reference on array and may replace the motif in the element by the value of another key :
the return value can be use directly like option for somes instructions
findParagraph(chapter[,section])
Find and return a reference of chapter finds in xml file , a section can be specified.
Functions
