[Magritte] Persistence for descriptions

Hi everyone.. i'm new in the Squeak/Seaside/Magritte world.. and i really like it

I thinks it's great the work you people are doing and eventually i would like to contribute in any way..

In the meantime i'm trying to use Seaside/Magritte for some projects, but i have a newbie question..

how can i implement persistence in Magritte in a simple way? Saving to the image? How often? Is this safe enought?

Thanks in advance

Humber

usually for a snapshot you should save multiple of them with
different name 01 02 10.
This is safe but some people are working on a database back end using
Magma. Esug is also trying to get a XML back end (but
so far nothing there).

Impara pubslihed in their source a back end for XML.

Thanks for the reply Stephane!

I tried magma a little bit and looks great! Does it work with a 3.9g-7057 image? I know i does with 3.8.

And if i just want to save the image periodically in the background? How can this be done?
Is there a working recipe?

Thanks!

There is also GOODS that is quite easy to use and that a lot of
Seasiders are using. It is a bit slow for huge amounts of objects
though.

There are several Web sites that discuss the advantages and
disadvantages of different persistency mechanisms in Squeak:

"UnixProcess saveImageInBackgroundNicely"

Requires SqueakMap->OSProcess
