Variables removed from class definition, but still referenced by code
by Josh Gargus 01 Feb '06

01 Feb '06

I have created a changeset in which a class is created with an iVar, methods added that reference that iVar, and finally the class definition is changed to remove the iVar. Newly created instances of the class behave as though the iVar is still present. Furthermore, when I add a new subclass that has an iVar of the same name, the class compiles OK (if the superclass had explicitly defined the iVar, I would not have been able to define it in the subclass). However, different slots are being accessed by superclass methods and subclass methods. In the following code (file in the attached changeset first): inst := ClassThatUsedToHaveAVariable new. inst add: 'string'. inst contents. subInst := ClassThatUsedToHaveAVariableSubclass new. subInst add: 'string2'. subInst subAdd: 'string3'. subInst contents. subInst subContents. 'subInst contents' and 'subInst subContents' do not give the same result. However, if the 'collection' variable is deleted from the subclass definition, they do answer the same result. What exactly are the semantics here? It seems like this could possibly cause some problems. Thanks, Josh

I have resorted to putting debug output to a file for now. At least I can now see my threads are dropping out. Probably take a while to find out why.

[Tweak] Latest stable version?
by Trygve Reenskaug 01 Feb '06

01 Feb '06

I find time to do further Tweak experiments and would like to base them on the latest stable version. http://tweak.impara.de/TECHNOLOGY/Download/ offers the download iTweak-3.8-6665.zip. Is this the latest? Tanks --Trygve -- Trygve Reenskaug mailto: trygver(a)ifi.uio.no Morgedalsvn. 5A http://heim.ifi.uio.no/~trygver N-0378 Oslo Tel: (+47) 22 49 57 27 Norway

SOAP system SUnit tests failing unless debugged?
by Simon Kirk 01 Feb '06

01 Feb '06

Hello all. I'm playing with the soap toolkit from SqueakMap, but something seems to be wrong: If I run some SUnit tests (specifically client ones - such as SoapHttpClientTestCase, or SoapCallTestCase) they are failing, saying they cannot connect to the server (localhost, port 8823). However, if I step through the tests via debugging, right into the point where the call is made to the server, the call appears to work fine (a connection is made, the expected return is received). What could be wrong here? It's almost like with the automated tests the server is dying before the tests are ever connecting.

Progress with bluetooth
by Davide Varvello 01 Feb '06

01 Feb '06

Hi All, Here is my first spike with squeak, bluetooth and osx, if you look at a previous thread you can see I use the ObjectiveC plugin by Avi. So.. the code: bundle := NSBundle bundleWithPath:'/System/Library/Frameworks/IOBluetoothUI.framework'. bundle load. selectorController := bundle classNamed:'IOBluetoothDeviceSelectorController'. deviceSelector := selectorController deviceSelector. deviceSelector runModal. deviceSelector getResults. If you paste it in a workspace you should see the selector window open itself and you can choose the bluetooth device you want to connect. bye Davide

[Morphic] More Nebraska Experiments
by Lic. Edgar J. De Cleene 01 Feb '06

01 Feb '06

Until what my troubles with Nebraska don't drive me to SqueakPlugin-dev.image, I never have contact with this out mainstream people / work. It's a so superior job of how one image used by a lot of people should be conducted what I beg this guys take the building process in his hands. They know what are doing and the result beat the official nonsense, none are running for any chair and do not insist on all must use his provided or die. I taking the work of take what is on up to day SqueakPlugin-dev.image and figure what I should have in 3.9 6705 for proper project loading (if you no have any problems , that's is why do you don't use Squeak) and for Nebraska working as was designed. I just have a first 3.9 6705 with Edgar glue seeing a SqueakPlugin-dev.image world (Need polishing and the other way too) I thanks Yoshiki for kind and guiding and extend to big number of unnoticed Squeak workers on World. GRACIAS AMIGOS DESCONOCIDOS Edgar ___________________________________________________________ 1GB gratis, Antivirus y Antispam Correo Yahoo!, el mejor correo web del mundo http://correo.yahoo.com.ar

Debugging a plugin
by Cowdery, Bob [UK] 01 Feb '06

01 Feb '06

Hi Can anyone enlighten me on the best approach to debug a plugin under Windows. The code essentially works in its native form but as a plugin doesn't do what it should, but doesn't crash or throw exceptions either. I would settle for getting hold of stdout/stderr but I can't get OSProcess to hook these and I read it doesn't yet support hooking the standard streams in Windows. I am using Dev-C++ to build the plugin and have tried pointing that at Squeak but it won't play.
