Re: [Pharo-users] Seaside and Fuel

Hi Jeff,
Or you can regularly serialize and save your data (every hour/day/whatever).

You can use Fuel as the serializer/materializer for the Simple Image Based Persistence scheme described here:
http://onsmalltalk.com/simple-image-based-persistence-in-squeak/


and implemented here:
http://www.squeaksource.com/SimplePersistence.html

Just subclass SPFileDatabase and override

SPFileDatabase class>>#saveRepository and SPFileDatabase class>>#lastBackup to use Fuel rather than the ReferenceStream


You'll need to specify what you want to save , when to save it, and how to restore it but the package above takes care of managing the backups.


I've attached a mcz file with a subclass that uses Fuel but you'll need to load the package on squeaksource as well first

Yes, this is something you can do for example with Pier. You can choose
how much regulary to save the data. In addition, it lets you choose how
many saves. Say you want max 3, then if there is a 4 save, it removes
the oldest one.  So you always have the last 3 saves.

I'cced the seaside mailing list which may have better ideas.

Cheers

I have been using it in my personal images from Pharo 1.2 through the last
1.3 rc with no problems

, but I haven't put it under much stress.

Whatever's best for the community. I'd be happy to add you as a dev (I
already added Paul) or make it global write. Just let me know.
