[Erp5-dev] Local version of ZMySQLDA and new version of ZMySQLDDA

[Pelletier Vincent]

Hi.

I've added to our repository a modified version of ZMySQLDA - MySQL connector 
product for Zope.
It contains modifications to make it work under Zope 2.8 - the original 
product has problems because Zope 2.8 removes volatile attributes from 
objects randomly during transactions.
As that change is quite heavy, I prefered to commit a local version rather 
than maintaining a patch during its development phase.

On the positive side, that change allows to get rid of all locks in ZMySQLDA 
(and at worse replace them by cheap & dumb flags), so this version should 
perform better than the standard one.
On the negative side, it breaks compatibility with current ZMySQLDDA, so I had 
to modify it aswell, and I will commit that new version tomorrow morning 
(EST).

Warning: This new ZMySQLDDA version will also depend on our local version of 
ZMySQLDA... So make sure to update both at the same time.

For both products, functionalities from "user" (ie, programer) point of view 
will remain strictly the same, with unchanged API.
