Bug in "about this system" reporting
by Tim Olson 25 May '98

25 May '98

Chosing "About this system" from the help menu fails when there are no updates (ChangeSorter>>highestNumberedChangeSet returns nil). Here's a fix: ---- 'From Squeak 2.0 of May 22, 1998 on 25 May 1998 at 9:55:29 am'! !ScreenController methodsFor: 'menu messages' stamp: 'tao 5/25/1998 09:54'! aboutThisSystem "Identify software version" | aString eToySystem aNumber | aString _ Smalltalk version.

(aNumber notNil and: [aNumber > 0]) ifTrue: [aString _ aString, ' Highest-numbered Change Set: ', aNumber printString]. ^ self inform: aString! ! -- tim

Just a suggestion
by ducasse＠iam.unibe.ch 25 May '98

Hi, I read the apple web page that describe the Squeak project. This page mentions the old 1.20 version. I think that could be good to say that such information is obsolete. Imagine a newcomer trying this old version instead of the new 2.0 Stef http://iamwww.unibe.ch/~ducasse/ "if you knew today was your last day on earth, what would you do different? ... especially if, by doing something different, today might not be your last day on earth" Calvin&Hobbes

Re: Re: Workspaces wasting memory

Hi Andreas. >The Workspace includes a dictionary with the bindings. All your undeclared >stuff can be found there. Try adding Silly me... the huge ByteArray I saw was then a 100kb byteArray I had in the workspace in question. I could ask for the keys of the dictionary to see what's going on... and indeed! I found a lost finiteStateModel, which I promptly nilled and got the few megabytes back. >Workspace>>releaseBindings > bindings _ nil Hehehehe... by the way, I noticed that workspaces also keep names pointing to nil... I would also include: Workspace>>cleanBindings bindings keysDo: [:each | (bindings at: each) isNil ifTrue: [bindings removeKey: each] ] >and then: Grin!... >This should give you most of the space back (given that it's really the >workspace bindings ;-) Well yes, a lost finite state model is quite a big structure. Talking about big memory requirements, how do I increase the amount of memory the virtual machine uses? Thanks! Andres.

Windows Morphic problem with "defer display update"
by William O. Dargel 25 May '98

25 May '98

I noticed a problem in the Windows version of the release of 2.0. When "defer display update" is checked for the VM, Morphs will disappear completely (along with the cursor) while they are being moved -- and don't reappear until after the mouse button is released. This happens only with the 2.0 image with the 2.0 VM (both regular and jitter). Substitute either the Beta image or the Beta VM (or both) and the problem doesn't occur. BTW, any chance of making it possible to set the VM options from the image and disabling the hot-key? I'd like to be able to use F2 in an application's interface. Actually, having just tried 'Sensor kbdTest', I'm wondering are the function keys currently available? or does it require a VM change? ------------------------------------------- Bill Dargel wdargel(a)shoshana.com Shoshana Technologies 100 West Joy Road, Ann Arbor, MI 48105 USA

PluggableListView bug in 2.0?
by Tim Olson 25 May '98

25 May '98

Hi, Squeakers: I'm trying to track down a bug I've been seeing in Squeak 2.0 -- it occurs when you open up a new File List and select a folder; in some cases it fails into the debugger when the PluggableListView attempts to send #controlTerminate to controller, and controller is nil. The things you have to do to make the fail occur are strange -- when you open up the new File List, make sure that the cursor is within the bottom or top right-hand panel, and don't move the cursor outside of these panels before clicking on a folder in the File List. If you move the cursor to the top left-hand panel or outside of the File List browser, the bug goes away. Has anyone else seen this, or can they recreate the problem with my description above? -- tim

Debugger Problem
by Andreas Raab 25 May '98

Hi, I noticed that there is a bug in the Debugger. The selection is not correctly updated due to wrong symbol in Debugger>>step sending #pc rather than #contentsSelection. Here is a fix: 'From Squeak 2.0 of May 22, 1998 on 25 May 1998 at 12:05:24 am'! !Debugger methodsFor: 'context stack menu' stamp: 'ar 5/24/1998 23:42'! step "Send the selected message in the accessed method, and regain control after the invoked method returns." | currentContext oldMethod | self okToChange ifFalse: [^ self]. self checkContextSelection. externalInterrupt ifFalse: [contextStackTop push: proceedValue]. externalInterrupt _ true.

Squeak 2.0 for Windows available
by Andreas Raab 24 May '98

24 May '98

Folks, I just wanted to inform you that the Windows VM has been updated to the Squeak 2.0 release. There is no big difference to the beta version except from the (now fairly complete) MIDI stuff which is now separate from the serial port. As usual, the VM is on ftp://ftp.cs.uni-magdeburg.de/pub/Smalltalk/free/squeak/win32/image/2.0/ http://isgwww.cs.uni-magdeburg.de/~raab/squeak/image/2.0/ Note that we had a few problems with the ftp server reporting that too many user have logged on so you may have to download the stuff from the my web site until this has been sorted out. Bye, Andreas -- Linear algebra is your friend - Trigonometry is your enemy. +===== Andreas Raab ============= (raab(a)isg.cs.uni-magdeburg.de) =====+ I Department of Simulation and Graphics Phone: +49 391 671 8065 I I University of Magdeburg, Germany Fax: +49 391 671 1164 I +=============< http://isgwww.cs.uni-magdeburg.de/~raab >=============+

Andreas, > Note that we had a few problems with the ftp server reporting that too > many user have logged on so you may have to download the stuff from the > my web site until this has been sorted out. Right. I had problems downloading from that. And, where are the VM sources? Ciao, Reinier.

2.0Beta for Unices
by Jörg Rade 24 May '98

24 May '98

Hi all, Ian Piumarta has made available his port of 2.0Beta for Unix. There are binaries for 4 platforms (Linux, Solaris, SunOS, OSF) and - of course - the C-source. Take a look at: ftp://alix.inria.fr/pub/squeak/unix/2.0Beta/ The FTP-Server supports auto-compress and auto-tar such that one may e.g. request ftp://alix.inria.fr/pub/squeak/unix/2.0Beta/image.tar.gz to retrieve a file with the contents of the image subdirectory. (A note of caution: this does not work with 'wget -c'). grtnx -j|g -- Joerg Rade | How could I know what I say | jr(a)petz.han.de Birkenstr. 32 | before I hear what I think? | +49 511 9887497 D-30171 Hannover +-----------------------------+ S: Schlaegerstr.
