puppetlabs/keystone can't find mysql::python

[Hugh Esco]

Even after upgrading puppetlabs-keystone to v3.1.1, at:
http://www.puppetforge.com/puppetlabs/keystone/3.1.1

I still get errors like:

Error: Could not retrieve catalog from remote server: Error 400 on SERVER: Could not find class mysql::python for dessalines-003.yourmessagedelivered.com on node dessalines-003.yourmessagedelivered.com

inspecting my puppet manifests, I see:

git:/etc/puppet/modules/dessalines# grep -R 'mysql::python' .
./test.rb: require 'mysql::python'
grep: ./mediawiki/spec/fixtures/modules/mediawiki/templates: No such file or directory
./keystone/spec/classes/keystone_db_mysql_spec.rb: it { should contain_class('mysql::python') }
./keystone/manifests/db/mysql.pp: require mysql::python
./keystone/manifests/init.pp: require 'mysql::python'

I was able to move past these errors by correcting those
references to use mysql::bindings::python, instead.

I recreated this bug as: Bug #1306745 in the keystone queue.
I suspect this bug can be closed. But will leave that to others to determine.

Any idea if this will be fixed? I'm hitting the same issue? Or should I use something else for the same (e.g. stackforge version of puppet-keystone)?

[Radoslaw Smigielski (radoslaw-smigielski)]

So in the keystone/manifests/init.pp there is a fragment of the code which detects type of the database [mysql|posgresql|sqlite] by looking at the connection sting. And according to the database type "requiers" dedicated db modules.

For MySQL support default value for mysql_module is 0.9 plus below fragment of keystone/manifests/init.pp is responsible for the include logic:

  if($database_connection_real =~ /mysql:\/\/\S+:\S+@\S+\/\S+/) {
    if ($mysql_module >= 2.2) {
      require 'mysql::bindings'
      require 'mysql::bindings::python'
    } else {
      require 'mysql::python'
    }

The bottom line is that:
1. mysql_module use to be >= 2.2 nowadays
2. by default mysql_module version 0.9 is assumed and the error about missing 'mysql::python' is thrown
3. by specifying your real mysql_module version in your keystone class, you can resolve this problem

IMHO we should not assume 0.9 as a default as it's very old or make "mysql_module" option mandatory?

[cooldharma06 (cooldharma06)]

Yeah i faced this error.

but you can resolve by 'overriding the mysql' version in your nova.pp(configuration) file

For ex: Currently puppetlabs-mysql version is 2.3.1

So in your configuration specify mysql_module => '2.3', this will make override the existing specified configuration and it will use the current mysql module.

i verified and its working.

Enjoy Puppet and Openstack. :)
