Re: [ANN] Connectors 1.2 available from SqueakMap

Very cool. When I downloaded it, I got a message that the install failed, but then everything seems to work, so I don't care much.

[VI4] Re: [ANN] AspectS (0.4.4) & PerspectiveS (0.1.3)

Aha! my theoretical nitpicking is not the only reason to remove UI stuff from the model! we'll add a preference on whether to bring up a debug/message to deal with errors. Anthony, maybe the same problem you found is ailing the Refactoring Browser in VI4?

[ANN] Spaghetti Tracer (0.4)
by danielv＠netvision.net.il 02 Nov '02

02 Nov '02

Now on SqueakMap. This version has a new analysis for multiple modules. This means you can now ask questions like "is Sunit hierarchially structured?" (yes) "is Balloon3D?" (well, not quite) "No? why not?" (you'll get a list of references that create a cyclic dependency between classes that are not in the same system category). Load it and do - mma _ MultiModuleAnalyzer onPackageNamedStarting: 'Balloon3D' mma isNonCyclic. mma packageStrongComponents. mma badStrongComponentsIn: mma packageStrongComponents. MessageSet openMessageList: mma cycleExampleForLargestPackageStrongComponent name: 'Methods that create one bad cycle'. More tutorial material is available on the SM package description, which I've cleaned up and updated. Especially if you maintain a package that spans more than one category, trying it out and let me know if it helps you find problems or find bogus problems, so forth. Daniel Vainsencher

Anyone have a room and want to go halves or thirds (I don't mind sleeping on a cot)? I've got a hostel budget. I'm pretty quiet and clean.

Anthony, Thanks for the compiler fix and tips on the order of initialization. Now I can file in both AspectS and PerspectiveS. I tried the first demo in the 'WS-AspectS.text': doIt: [demoAspect _ AsMorphicMousingAspect new] doIt: [demoAspect install] I got 'UndefinedObject do:?'. (This demo works OK for VI3). Please find attached the log file.

RE: An uncomfortable question
by Swan, Dean 02 Nov '02

02 Nov '02

Well, having foolishly participated in the recent little brouhaha (no pun intended) over this issue, I would like to wholeheartedly concur with Roger here. Also, I think this gets back to addressing Andrew's original issue of forking. And yes, it would be great fun to debate where to draw the SBP line. I could certainly see reasonable arguments for places other than Squeak 2.8. -Dean -----Original Message----- From: Roger Vossler [mailto:rvossler@qwest.net] Sent: Friday, November 01, 2002 6:49 PM To: squeak-dev(a)lists.squeakfoundation.org Subject: Re: An uncomfortable question Hi Gang, About 18 months ago, I pointed out to this list that modules, or components, are a complex and very difficult problem. I was ignored. Recently, a number of folks on this list have come to the hot conclusion that modules, or components, are a complex and very difficult problem. What a surprise. So, just this once, I'm going to say, "I told you so." :-) Before anyone gets serious about modules, or components, they must deal with issues of architecture and interfaces before they get down into the design and implementation details of modularity, namespaces, interdependencies, et al. While there have been a few references to "architecture" and "interfaces" on the list over the past 18 months, the focus has been on design and implementation, which puts the cart squarely before the horse. Having said all of this, where do we go from here? I have a few suggestions: 1. Squeak 3.3 is a dead duck which should be set aside as: (1) a source of ideas for any future work on modules, (2) a monument to ambition over common sense engineering, and/or (3) a mechanism for torturing graduate students (re: thesis advisor to PhD candidate says, "Here. Take this code and make it work".) 2. Squeak 3.3 should be salvaged for anything that can be backported to 3.2. Some of this has already happened. 3. Continue the Squeak development stream starting with Squeak3.2-4956, which appears to be the last "stable" version. Add the Squeak Map and related stuff (Vainsencher, et al). Add the VI4 stuff (Hannan, et al). Package the results of all this as Squeak 4.0 and declare victory. 4. Squeak 4.0 should become the Squeak upper bound while Squeak 2.8, or Stable Squeak, should become the Squeak lower bound. Somewhere between the upper bound and the lower bound, define a Squeak Base Platform (SBP). The SBP becomes a thoroughly debugged and documented platform from which the fans of modules can work as well as a platform for other folks who might want to use Squeak for something useful. We can have lots of fun fighting over where to draw the SBP baseline. I am serious about this. Squeak 2.8 is more than enough for me to handle. Squeak 3.2 is about three (3) times the size of Squeak 2.8. Whatever happened to that "exquisite personal computing environment that one person can comprehend"? With or without modules, nobody is capable of fighting their way through hundreds of thousands of lines of code. Apparently, this fact has torpedoed the various module efforts to date. Well, this is more than enough for now. Cheers, Roger.....

The object is asked for its executor - the thing that deals with cleaning up after its death. The executor typically maintains a copy of sufficient of the object's state to be able to do the cleanup. - Peter

OOPSLA Squeak BOF on Tuesday 7:30pm
by Doug Way 02 Nov '02

02 Nov '02

Just wanted to verify that it looks like the Squeak BOF (Birds Of a Feather session) at OOPSLA will be on Tuesday evening at 7:30, right after the welcome reception. There are usually several interesting demos at the BOF... anyone mildly interested in Squeak is welcome to attend. This is technically a day earlier than usual, since OOPSLA is pushed back to Monday-Friday this year. But the idea was that most BOFs (including Cincom's) are on the third evening of the conference and then a lot of people would miss the Squeak BOF. People seemed agreeable to this time when it was discussed on the list in late September, so I'm assuming that it is a go. (If there are major objections, please post them now. :-) ) I will post something to comp.lang.smalltalk about it, so that other curious Smalltalkers can attend, too. - Doug Way dway(a)riskmetrics.com

The attached changeset fixes this. This is the bug you saw when filing in AspectS. The PerspectiveS bug is do to initialization code being out of order in the PerspectiveS changeset. PsContext initialize! should be before PsTestContext initialize! I found this after disabling the error handling in SMDefaultInstaller-install. As a programmer I prefer to get a walkback versus just a popup saying that the install has failed. Goran, good job with SqueakMap. It is great! Cheers, Anthony
