RE: ODBC connection
by Welch, Ronald P (US SSA) 01 Dec '04

01 Dec '04

Yep, I have tried Tantalus. It is good, but I see it as a more "conventional" approach to object relational mapping. I like the approach Avi and company took with ROE, namely modeling the relational algebra itself rather than attempting to abstract it away. Having said that, we are up to our eyeballs around here in Oracle databases but Postgress is pretty rare, hence my question. It is not a big deal though. I was just wondering if anyone had played around with Oracle and ROE. ----------=-=-=-=-=-=-=-=-========oOo========-=-=-=-=-=-=-=-=---------- mailto:Ronald.P.Welch@baesystems.com Phone:(607)770-3701 BAE SYSTEMS Controls 600 Main St Johnson City, NY 13790-1888 ----------=-=-=-=-=-=-=-=-===================-=-=-=-=-=-=-=-=---------- -----Original Message----- From: Pablo Iaria [mailto:iariap@hotpop.com] Sent: Monday, November 29, 2004 1:38 PM To: 'The general-purpose Squeak developers list' Subject: RE: ODBC connection Hi Ronald, mmmmmm...ROE only works with pgsql I have tried tantalus (another small mapping tool) and it worked fine with ODBC.

When can we have SqueakMpa package version aware...
by stéphane ducasse 01 Dec '04

01 Dec '04

Hi goran We would like to be able to manage the code of some packages with squeakMap but without having to create one package for each version (look at RB for example). Have you plans to have that? Stef

Re: About removing global variables
by Brian Rice 01 Dec '04

01 Dec '04

It's quite simple: There's not enough attention span to go around to cover or meaningfully debate any interesting ideas on this list. It's taxing just to follow ODBC discussions, let alone try to appreciate everyone's opinion and solution on global namespace structure.

{Spam?} Data conversion using #primitiveChangeClassTo: with GOODS
by Yar Hwee Boon 01 Dec '04

01 Dec '04

I'm trying to convert some objects that is stored in GOODS to their subclass, but I'm not sure why its not working. Could anyone have a look? File in the attached and run the code below. How should I do this instead? Thanks. ====== db := KKDatabase onHost: 'localhost' port: 6102. a := AA new. a list add: BB new. db root at: #xxx put: a. db commit. x := (db root at:#xxx). "x list do: [:e | e primitiveChangeClassTo: BBSubclass new]." x list: (OrderedCollection with: (x list do: [:e | e primitiveChangeClassTo: BBSubclass new])). "x inspect" db commit. db := KKDatabase onHost: 'localhost' port: 6102. (db root at:#xxx) inspect ====== -- Regards HweeBoon MotionObj

About Smalltalk at: .... ifAbsent:/present:
by stéphane ducasse 01 Dec '04

01 Dec '04

Hi guys this afternoon we spent one hour with marcus looking at all the senders of at:ifPresent/ifAbsent: by looking at all the references to Smalltalk (far too much again but we will fix that soon). It occurred to us that there is something strange because there are a lot of recurrent code. It seems that: - first it would be better to let the compiler compiles method with reference to classes that are not in the system and let the system complain at execution tim (marcus suggestion and he can explain that much better than me). - second, it occurred to us that packages are missing in some cases because having a dependency mechanism (I'm not sure that it is the solution) would make sure that the code needing to be invoked is present in the image by the structural dependency between packages or registration where optional code can be declared We would really appreciate to get you open a browser, look at the code (clean if you identify some dead code, ugly methods ;)) and share with us your impressions. And what are the solutions you see, because it seems to us that there are far too much use of this idiom. Stef
