Hi!

I'd like to show a bit the outcome of the first iteration of the DBXTalk Gsoc of this year.

First, I've been adapting myself to the environment and technology (DBXTalk, OpenDBX, TalkFFI), and I've written some little tutorials of what I've learnt about them:

- Post of how to install �OpenDBX

http://rochiamaya.wordpress.com/2013/07/28/how-to-install-version-1-4-6-of-opendbx-for-linux/

- Post of how to install and use TalkFFI to generate mappings

http://rochiamaya.wordpress.com/2013/07/30/create-bindings-with-talkffi/

- Post �of how to use �mappings generated �by �TalkFFI

http://rochiamaya.wordpress.com/2013/08/06/how-to-use-the-generated-bindings-talkffi/

Also, as concrete code, we have built a NBFFI version of the OpenDBXDriver. The main idea of this is to provide a backward compatibility layer to people that �use OpenDBX, while letting us move forward dropping the old FFI implementation.

Gofer it

smalltalkhubUser: 'DBXTalk' project: 'Configurations';

configurationOf: 'OpenDBXDriver';

load.

(((Smalltalk at: #ConfigurationOfOpenDBXDriver)

��perform: #project)

������perform: #version: with: �1.3�)

����������load: 'DeveloperGroup'.

However, the configuration still supports to load the former version of the driver (no NBFFI)

�Gofer it

smalltalkhubUser: 'DBXTalk' project: 'Configurations';

configurationOf: 'OpenDBXDriver';

load.

(((Smalltalk at: #ConfigurationOfOpenDBXDriver)

��perform: #project)

������perform: #version: with: �1.3�)

����������load: 'FFIDriver'.

And the configuration with only NBFFI version.

�Gofer it

smalltalkhubUser: 'DBXTalk' project: 'Configurations';

configurationOf: 'OpenDBXDriver';

load.

(((Smalltalk at: #ConfigurationOfOpenDBXDriver)

��perform: #project)

������perform: #version: with: �1.3�)

����������load: �'NBFFIDriver'.

To use, writte in the Workspace and DoIt:

�to set the NBFFI bind�

LibOpenDBXMap initialize.

OpenDBX current: NBPharoOpenDBX new.

�or to set the oldFFI bind�

OpenDBX current: FFIOpenDBX �ffiImplementationForOS .

In our current/next steps, we are starting to dig into the other driver implementations. I'm currently working in a Mysql driver implementation that will use the C mysql library directly without the intermediation of OpenDBX. That way, the setup of the environment will be far easier and the entry barrier will be lowered.

Best Regards!
