Nebraska window coming up empty
by Derek Brans 03 May '03

03 May '03

Bob, thank you for your last answer. Here's my next Nebraska challenge: I have two squeak images running on the same machine. In one, I've typed: NebraskaServer serveWorld: World onPort: 8092. In the other, I've typed: (NetworkTerminalMorph connectTo: '127.0.0.1' port:8092) openScaled An orange window comes up, but nothing appears in it (Normally I see a scaled version of the server's world). Any suggestions? Thank you Derek Brans Nerd on a Wire Web design that's anything but square http://www.nerdonawire.com phone: 604.874.6463 mailto: brans(a)nerdonawire.com

I'm not trying to suggest that what you describe isn't a very efficient way to find and fix problems. I just suggesting that being able to view a summary of the expected and actual results of failed tests within sUnit's TestRunner Window (or in a Transcript) could be useful. Often, I've found it isn't necessary to step through the test code in order to see what's broken. Bringing up the debugger and discovering the actual and expected values on failed tests takes several more clicks than it would of taken if that info was displayed in sUnit. Having browsers open on one's test case and class undergoing tests along with sUnit displaying actual & expected info would, in many instances, allow for a faster run test->write/fix code (or even fix test) cycle. In such a set up you could fix the problem "on the spot" faster in cases where the comparison of expected and actual results leads to a immediate correct deduction of what was wrong (such as in a spelling mistake made in the test's expected result). > The best way to explain this would probably be to > pair... Yes, that sounds like a good way to make clear the efficient use of debugger and sUnit. However, I don't know any Smalltalkers where I live. Perhaps, I should look into seeing if there's a local Smalltalker Users Group. Thanks for your advice, Anthony __________________________________ Do you Yahoo!? The New Yahoo! Search - Faster.

[BUG] Nebraska Server is broken

Try typing NebraskaServer serveWorld: World onPort: 8092 in a vanilla 3.4 or 3.5 image.

Does Collection allSubInstances include itself?

I suppose it does. Just a random late-night thought. Derek Brans Nerd on a Wire Web design that's anything but square http://www.nerdonawire.com phone: 604.874.6463 mailto: brans(a)nerdonawire.com

Re: Debian Squeak VM package depends on a newer version of libc6 thanis available

Or you can add the testing source instead of replacing, and then apt-get install <yourpackage> -t testing. No guarantees, but I use this to use unstable versions of some packages while generally living in stable.

Re: Aggregated removal script for 3.6

And I'd add that people experience reports/reviews of the removal package with or without reloading the package are welcome.

DVS doesn't show changes?
by Eric Scharff 02 May '03

02 May '03

Recently having upgraded to 3.5, I finally wanted to start playing with DVS. The fileIn and fileOut features seem to work as expected, but the "changes" choice doesn't seem to do anything. Here's what I do 1. create two images in the same folder, im1 and im2 2. Switch to im1 3. Use the DVS package browser to create a new package - EFoo 4. Add some methods to the package 5. fileOut the package. I notice that all the EFoo-* methods are in the resulting .st file. So far so good. 6. Switch to im2 7. Load the EFoo package into the package browser 8. Great! The classes are now there. 9. Modify the classes, add some methods, change some, ... 10. Go back to the package browser - there is a * next to the package. Good, it has changed. 11. hit the "Changes" button, to compare the current version to the one on disk. IT DOESN'T DO ANYTHING. I get an empty message browser. 12. ok, well file-out the package. Again, that works, and the changed things are in the resulting .st file. 13. switch back to im1 14, now, the version on disk is newer than the stuff in im1 15. I don't get any indication of changes from DVS 16. Again, hitting the "Changes" button doesn't do anything. 17. But, I can fileIn and it does properly add the methods. The change features (of both CVS and DVS) are really important to me. Otherwise, I'm just going to continue to use change sets since browsing changes is so important. Did I do something obviously stupid or wrong? -Eric

Debian Squeak VM package depends on a newer version of libc6 thanis available
by Derek Brans 02 May '03

02 May '03

The squeak-vm package depends on libc6 2.3.1, but when I do an install using apt-get, the newest stable version is 2.2.5 Any suggestions? Thank you. Derek Brans Nerd on a Wire Web design that's anything but square http://www.nerdonawire.com phone: 604.874.6463 mailto: brans(a)nerdonawire.com
