I've had a long day.

eh? I said my solution does use this driver.
I dont believe that the driver was originally written by Alan Reider, I
used it back in March 2003 and it was already old enough to have been
published and have no current maintainer. Alan took up the mantel and
added some additional support for more recent versions of MySql, there
are even bug reports on Mantis referring to this driver, indicating that
it works, apart from particular new datatypes. As far as I know Alan
added support for the new password scheme, which adds a dependency on
Cryptography. If you look at Package Universes I think that this
dependency is listed.
The recent update to squeaksource, is due to the fact that I reminded
Alan of the existence of the squeaksource repository, he had been
maintaining it elsewhere.
My, fairly recent, contribution has simply been to begin to add a
factory pattern so that this driver may potentially support multiple
versions of MySQL since there are some slight variations between versions.

Ok, so actually how many seaside projects using post-stress and glorp
are published on seaside (ok I havent even looked) but its not that
many... I was contesting your point that MySql isnt used by the seaside
community. Didn't Tantalus and ROE use MySQL. Heck if you look on
SqueakMap you will see that version 1.10 of MySql is/was downloadable
from wiresong.ca, isnt that Avi's server!

I didnt say that... actually I have been told that there is a company
which has it working with Glorp, I just haven't seen it for myself.

Magritte is fantastic, its not even very complicated, its just fairly
logically complete. If you are going to be taking data and rendering it
into a seaside component, with validation etc, if you write anything
vaguely generic, you are going to be aiming and probably failing to
attain the functionality of magritte.
Using some extensions to magritte which support scriptaculous, it is
getting to the point where it is possible to write whole seaside app's
just through magritte's data descriptions. This includes MySql
persistency, dependencies between fields, dynamic component visibility etc.

It might be worth writing something about the new dynamic extensions
that I wrote for magritte. Magritte itself has far better documentation
than I could write.

That might just be the dependency on Cryptography

Dont think so.

contains a fairly easy to follow database interface class which is the example that I learnt from.
I will see about including a refined version in the distribution.
I do think that the MySql Driver is needlessly complicated in areas, probably an artifact of its Java heritage.
