Questions

@hernanmd maybe it would be easier to discuss here as questions arise instead of the Pharo ML (but I copied this into a thread on the users list anyway he he). After we can try to fold back answers into the docs?

Repository Access

The following code seems problematic:

ASRepository class>>#repositoryNamed: aString
	…
	^ self allInstances detect: …

Isn't it possible that a rogue instance could be returned instead of the one that's part of the model? For example, some persistence libraries like SimpleImagePersistence replace segments of the object graph and might have the old and new copy present during a load.

Where do Check Points Live?

In the IGEVET app, it seems that each session hasA checkPoint which hasA repository. Is this the way you’d recommend using AS in a real app? It seems that the default repository implementation loads the whole user DB from disk via Fuel, so wouldn’t that happen for each session?!

[hernanmd]

Thank you for reporting this Sean, and sorry for the late response.

I never tested for more than 3 or 4 users so it has never been an issue. But you are right, currently the CP loads the whole Fuel DB for each session.

The best I can think to fix both issues would be to make ASRepository a Singleton. Let me know if you have another suggestion.
