[Glass] New user can't access GLASS & other classes

[James Foster via Glass]

Jerry,

I agree that it would be nice if the technology did not dictate a particular usage pattern, and I appreciate your recognition that there are a variety of factors involved in the community/open source project. Not as a way to convince you to do something else, but as a way for me to better understand people’s use of the system, I’d like to understand why you “really dislike the idea of developing as DataCurator”. While you are right that it doesn’t make sense to think of GemStone as a “single-user system” in a production sense, I wonder if it does make sense to think of it that way for development. Even for production, might it be best to think of it as a “single-application system” such that letting DataCurator own the application (as SystemUser owns the system)? What are your issues with DataCurator?

James

However, when I tried to do anything with the UserGlobals inserted into the test user symbol list, I started getting security violations. This was kind of expected as I didn’t think that sharing UserGlobals this way would be appropriate anyway, for several reasons. I just wanted to see if it was possible to bypass GS security by messing with the dictionaries this way. Apparently not :)

The idea was that JKTestUser’s UserGlobals would have its own class hierarchy for GLASS etc. That didn’t work either, failed with compilation errors.

This probably has something to do with Pharo/Seaside being essentially a single user system. However, I really dislike the idea of developing as DataCurator, so I am thinking that I would create some abstract classes and new ‘globals’ in the Published dictionary pointing to GLASS stuff. That might provide access to the things that I need as a ‘developer’ user. Naturally, the tricky part here will be to get a useable IDE working. Tode will only work with the bootstrapped GLASS, so it’s a bit of a chicken and egg situation.

I copied the content of my devKit_34 session profile and changed only the credentials. I have created a new client (tode2), in which I can see the two session profiles (devKit_34 and jkTest_34). I can log in to the stone (which is running on another host but that’s not a problem - I have ssh port forwarding set up and it works for both tode1 and tode2 clients).

I’ve tried several different ways to put them into the JKTestUser symbol dictionaries (insert a new one, or put the classes in the Published dictionary), but when I do that, I get an error ‘improper store’ with some parameters.
