In fact, I guess all Fuel versions will be like that. It is really difficult not to change the format at all. So...is it worth to update to 1.8? it depends on your needs. 1.8 provides new features (hooks) and some better performance. - If you already have only a few data and it would be easy to migrate then I would do it. - If it is too much data, then I would stay in 1.7 until you really need something from 1.8. - If you need something of the new features/hooks of 1.8 or the speed is crucial, then I would update to 1.8. > If not is there a recommended process to switch from one format to the > other? > > I'd assume starting from a clean pharo you could: > 1. load Fuel 1.7 > 2. materialize all the interesting Fuel 1.7 objects > 3. removing Fuel 1.7 > 4. load Fuel 1.8 > 5. serialize all the interesting objects in Fuel 1.8 > > Exactly.

All I can say is that you can pass to Fuel any stream (even Zinc ones). So you can do: FLSerializer newDefault serialize: 'whatever' on: aZincWriteStream you may need to implement some extension methods to Zinc streams. I think Nick already did them. If it is helpful, we can create a package Fuel-Zinc that adds such extension methods, just as we did for FuelFileSystem. > > Thanks for your work on this. > > -- Mariano http://marianopeck.wordpress.com

Fuel 1.7 vs Fuel 1.8 questions

by Paul DeBruicker

Is there a strong reason to switch to 1.8 vs 1.7 other than the fact that 1.8 is the new hotness? I remember that you made no guarantees but are Fuel 1.7 and Fuel 1.8 serialized formats compatible? If not is there a recommended process to switch from one format to the other? I'd assume starting from a clean pharo you could: 1. load Fuel 1.7 2. materialize all the interesting Fuel 1.7 objects 3. removing Fuel 1.7 4. load Fuel 1.8 5. serialize all the interesting objects in Fuel 1.8 I have not looked at the code but is there a way to do a streaming 'serialize to byte array' in conjunction with Zinc for populating a database? Thanks for your work on this.

Fuel works out of the box in Pharo from 1.1 up to 2.0 (checked at > #20094). Please check our documentation [2] for complete installation > and use guides Martin told me something by private email that I think is worth to mention. Not sure if you read it carefully, but Fuel is working from Pharo version 1.1 up to 2.0!!! One of reasons is to help people migrate to new Pharo versions by using Fuel as a way of moving data.
