LCFG profile handling

Over the last few months the new libraries for handling LCFG profiles have been shaping up nicely. They are finally reaching a point where they match up with my original aims so I thought I’d give a taste of how it all works. Here’s an example of processing an LCFG XML profile into the Berkeley DB and rpmcfg files required by the client:

use LCFG::Profile;

my $xml    = '/var/lcfg/conf/profile/xml/example.lcfg.org.xml';
my $dbm    = '/tmp/example.lcfg.org.DB2.db';
my $dbm_ns = 'example';
my $rpmcfg = '/tmp/example.lcfg.org.rpmcfg';

my $new_profile = LCFG::Profile->new_from_xml($xml);

my $update_dbm = 0;
if ( -f $dbm ) {
    my $cur_profile = LCFG::Profile->new_from_bdb($dbm);

    my $diff = $cur_profile->diff($new_profile);

    if ( $diff->size > 0 ) {
        $update_dbm = 1;
    }
} else {
    $update_dbm = 1;
}

if ( $update_dbm ) {
    $new_profile->to_bdb( $dbm, $dbm_ns );
    say 'Updated DBM';
}

my $pkgs_changed = $new_profile->to_rpmcfg($rpmcfg);
if ( $pkgs_changed ) {
    say 'Updated packages';
}

This is basically what the LCFG client does whenever it processes a new profile but is a lot nicer than the current rdxprof code!
