Hi all, this tiny goodie removes all entries without references from Undeclared. Maybe this should be called after every file in.

[BUG][FIX]SelectionMorph organizeInto[Row/Column]
by tblanchard＠mac.com 22 Aug '04

22 Aug '04

This fixes the very annoying organizeIntoRow and organizeIntoColumn features in SelectionMorph. Previously it ordered the items by their front to back order - which resulted in an inversion of my list. These changes first sort the selected items top to bottom (column) or left to right(row) so you get something a little closer to what you likely envisioned when you executed the command.

[BUG] - NameLookupFailure(Exception)>>retry
by John M McIntosh 08 Aug '04

08 Aug '04

Lets see. First disconnect computer from network, then start squeak, then do help->update code from server which then attempts to resolve the squeak public server name, which of course is going to fail, however now we get an unexpected failure of a different sort since when we execute: (NameLookupFailure hostName: hostName) signal: 'Could not resolve the server named: ', hostName with the response choice of Give Up or Retry. and I Pick Retry. handlerContext is nil, so we get a "does not understand..." Anyone care to fix this? ----------------------------------------------------- 16 October 2003 4:40:32 pm VM: Mac OS - Squeak3.6gamma of '11 September 2003' [latest update: #5420] Squeak VM 3.6.0b3 Image: Squeak3.6 [latest update: #5424] UndefinedObject(Object)>>doesNotUnderstand: #restart Receiver: nil Arguments and temporary variables: aMessage: a Message with selector: #restart and arguments: #() Receiver's instance variables: nil NameLookupFailure(Exception)>>retry Receiver: NameLookupFailure: Could not resolve the server named: update.squeakfoundation.org Arguments and temporary variables: Receiver's instance variables: messageText: 'Could not resolve the server named: update.squeakfoundation.org' tag: nil signalContext: NameLookupFailure(Exception)>>signal handlerContext: nil outerContext: nil hostName: 'update.squeakfoundation.org' NameLookupFailure>>defaultAction Receiver: NameLookupFailure: Could not resolve the server named: update.squeakfoundation.org Arguments and temporary variables: response: 1 Receiver's instance variables: messageText: 'Could not resolve the server named: update.squeakfoundation.org' tag: nil signalContext: NameLookupFailure(Exception)>>signal handlerContext: nil outerContext: nil hostName: 'update.squeakfoundation.org' UndefinedObject>>handleSignal: Receiver: nil Arguments and temporary variables: exception: NameLookupFailure: Could not resolve the server named: update.squeak...etc...

[FIX] TextMorphBuglet
by bparsia＠email.unc.edu 04 Aug '04

04 Aug '04

from preamble: "Change Set: TextMorphBuglet Date: 1 December 2003 Author: Bijan Parsia Another in a series of microfixes. This showed up when using the codeProvenance button to toggle colorPrinting from prettyPrinting. Since the actually characters didn't change, the display wouldn't update until you went to another method, or cycled through some other display mode. This fix follows the advice in Text>>=. I expect it'll slow somethings down, especially for complex texts (e.g., with embedded morphs). It may be better to change how this test logic works, but now, at least, the behavior is correct."!

[ENH] UsableSiblingInstanceFix-nk
by Ned Konz 04 Aug '04

04 Aug '04

from preamble: "Change Set: UsableSiblingInstanceFix-nk Date: 11 October 2003 Author: Ned Konz Morph>>usableSiblingInstance was always adding the created sibling to the World, even though many of its callers would turn around and immediately add the result to other morphs or delete them from the World. This change set makes #usableSiblingInstance not add the newly created Morph to the World. This makes several uses of #usableSiblingInstance more bug-free and efficient. "!

[bug] stack overflow crashes Squeak.
by Michael van der Gulik 06 Jul '04

06 Jul '04

Hi all. If you make a naive class that calls itself: Forkbomb>>forkbomb ^ self forkbomb. Squeak 3.5 on Debian linux will eventually crash, leaving a huge stack dump in the terminal. Okay; it's really my fault for making such a stupid class, but I'm playing around with proxied objects, message sends etc and it's happening quite often while I'm debugging. Is there a way to limit the invocation stack to a sane level of deepness, after which a process/thread (whichever is Squeak terminology) gets suspended and an error thrown? Same probably applies to number of processes made by a thread. mikevdg.

The Magic Book - a design draft
by goran.hultgren＠bluefish.se 30 Jun '04

30 Jun '04

The idea of a "Magic Book" inside Squeak acting as both an introductory documentation for Squeak and as a reference manual is quite intriguing. A few basic ideas that got this started: - Tying unit tests to documentation in order to detect stale documentation - Not bloating the image - Easily maintain the book cooperatively (like swiki) Ok, what would be the STTCPW? (For all you non XP aware: "Simplest Thing That Could Possibly Work"). By applying reuse - what do we already have? We already have: - Projects: A very good format for "active content". I am not sure how easily they are backwardscompatible though. Could anyone post some insight in that matter? - StarBrowser: A universal UI kindof thing. We could easily let StarBrowser be the main UI of the Magic Book! It lends itself easily for the task - a treeview on the left, a dynamic area to the left etc. If we somehow find a good way to integrate a little search form then it would be quite perfect. - SqueakMap: In whichever form we choose to have the Chapters of the book (Projects) we could register them on SM (a few new categories would be nice) and thus get a distributed always up to date model of chapters for free. And when SM1.1 gets completed it will track versions of the chapters for us, etc. And in SM1.1 it will have a sensible smart diskcache for the packages (read Chapters) so we get that too. - Free text engine: Scott Crosby wrote a neat little engine for maintaining keyword indices that the book obviously should use. I have also been intending to integrate that into SM. We should be able to add it to SM in such a way that the Magic Book can simple get that "for free". So... we already have a bunch of cool technology to implement the Magic Book IMHO. We just need to knit it all together in a smart way. If we split the book in the following pieces: 1. The TOC. This is essentially a list of chapters organized in a hierarchy with names and a link to the corresponding SM package that is the chapter content - a Project. 2. The chapters themselves. These are simply Projects published as packages on SM. Perhaps we need to follow a few conventions for these Projects so that we easily can "jump into" them in a proper manner, extract keywords for indices etc. 3. The search indices and the index (as books have last). If 1 and 2 above also are packages on SM (in whichever suitable form, doesn't matter) it will be even more simplified. So the book *contents* are then managed as packages on SM. We get the possibility of having different owners for different chapters, release/version tracking etc. It is obvious when you think about it - why shouldn't they be packages? The StarBrowser is the obvious choice of a UI - it already has navigation mechanisms and it can also show contents from the book along with other things in a highly dynamic fashion. Why reinvent that? And SqueakMap gives us a lot of stuff like efficiently always updated content, a smart cache etc. And there will be no image bloat whatsoever. Well, ok, what do you all think? Darn, this sounds like real fun... I need to get cranking at my SM1.1 ... :-) regards, Göran
