I gave ZMySQLDA a quick once-over and I THINK this will convert it from
using MySQLmodule-1.4 to _mysql. Why _mysql and not MySQLdb? Well, look
at the patch. :) It's basically puny. ZMySQLDA abstracts away the Python
DB API interface anyway, so why wrap another wrapper? Plus, by default
MySQLdb attempts to do type conversions, which Zope doesn't seem to expect.
I made some changes, partially to help Zopistas, to both _mysql and MySQLdb.
The main one is removing type_conv as part of _mysql. It now needs to be
passed to _mysql.connect() as the conv keyword argument; if it is not present,
it uses an empty dictionary (return everything as strings), which is the
Zope-desired behavior. MySQLdb now owns type_conv, and passes as copy if
you don't supply your own converter.

Special note: Not only is the MySQLdb package provided WITH NO WARRANTY,
this patch is DOUBLE-SECRET NO WARRRANTY. It may not work at all; I have
not tested it PERIOD. I am using Zope-2.0.0a4, but I don't really have the
time to whip up something to test with. The Digicool guys can figure out
whether or not it works. If it makes your testicles fall off (or you grow
some when you shouldn't have any), I am not responsible.

Oh yeah, to apply the patch, you probably want to use:

	patch -p1 <ZMySQLDA.patch
