Doc Type: Bug Fix
Doc Text:
In an IPv6-based Overcloud, the director incorrectly parsed MariaDB DSN strings containing IPv6 addresses. This caused Puppet to report duplicate 'Mysql_database' resources due to all databases using the first bit grouping of the IPv6 address as the database name (e.g. 'fd00'). This fix adds logic to check if the string uses an IPv4 or IPv6 address and parse the string accordingly. Puppet no longer reports duplicate 'Mysql_database' resources.

Comment 5 Sofer Athlan-Guyot 2016-01-16 11:26:16 EST 
In the created manifest on the controller node we have this:


    $allowed_hosts = ['%',hiera('mysql_bind_host')]
    $keystone_dsn = split(hiera('keystone::database_connection'), '[@:/?]')
    class { 'keystone::db::mysql':
      user          => $keystone_dsn[3],
      password      => $keystone_dsn[4],
      host          => $keystone_dsn[5],
      dbname        => $keystone_dsn[6],
      allowed_hosts => $allowed_hosts,
      require       => Exec['galera-ready'],
    }
    $glance_dsn = split(hiera('glance::api::database_connection'), '[@:/?]')
    class { 'glance::db::mysql':
      user          => $glance_dsn[3],
      password      => $glance_dsn[4],
      host          => $glance_dsn[5],
      dbname        => $glance_dsn[6],
      allowed_hosts => $allowed_hosts,
      require       => Exec['galera-ready'],
    }
    $nova_dsn = split(hiera('nova::database_connection'), '[@:/?]')
    class { 'nova::db::mysql':
      user          => $nova_dsn[3],
      password      => $nova_dsn[4],
      host          => $nova_dsn[5],
      dbname        => $nova_dsn[6],
      allowed_hosts => $allowed_hosts,
      require       => Exec['galera-ready'],
    }
    $neutron_dsn = split(hiera('neutron::server::database_connection'), '[@:/?]')
    class { 'neutron::db::mysql':
      user          => $neutron_dsn[3],
      password      => $neutron_dsn[4],
      host          => $neutron_dsn[5],
      dbname        => $neutron_dsn[6],
      allowed_hosts => $allowed_hosts,
      require       => Exec['galera-ready'],
    }
    $cinder_dsn = split(hiera('cinder::database_connection'), '[@:/?]')
    class { 'cinder::db::mysql':
      user          => $cinder_dsn[3],
      password      => $cinder_dsn[4],
      host          => $cinder_dsn[5],
      dbname        => $cinder_dsn[6],
      allowed_hosts => $allowed_hosts,
      require       => Exec['galera-ready'],
    }
...

The problem when using IPv6 is this idiom : 

   split(hiera('cinder::database_connection'), '[@:/?]')

It works ok for ipv4, but with ipv6, ":" is part of the url.  For
instance:

   cinder::database_connection = mysql://cinder:7ZT8sXWMxQMm2wVGWEEvjpCbm@[fd00:fd00:fd00:2000:f816:3eff:fec7:b967]/cinder

giving dbname=fd00 instead of cinder.  This is true for all
".*::database_connection".

Then all the database will be named "fd00", giving rise to the
aforementioned error.
