Hmm it looks like some UTF8 mess I did only change Base64MimeConverter...

Note that it is indeed complaining that BlockContext doesn't understand #'' ! The error appears immediately after this runs: OGLUnixX11LE >> openGLLibraryName ^Smalltalk osVersion = 'linux' ifTrue: ['libGL.so.1'] ifFalse: ['GL'] Now on my machine Smalltalk osVersion = 'linux-gnu', but I get the weird error even when I change the conditional to `Smalltalk osVersion beginsWith: 'linux'`. I find it utterly bizarre that something should try to send #'' to anything after this call. Clearly something's gone wrong, and it's almost certainly not the CCSE. Any ideas? frank

Updating the swiki
by tim Rowledge 06 Aug '13

06 Aug '13

I try to update a page or two on the swiki every day. Sometimes all it involves is a small correction to a dead link, or some minor grammatical twiddle. Sometimes it is wholesale slaughter to remove pointless deadwood (and there is a distressing amount of it!) If everybody tried something similar, even just once a week, forget once a day, we would soon improve things. Consider spending just 5 minutes to scan or search or even randomly pick a page and then fix anything wrong with it. Take a quick look at pages pointing to it and see if they need some care. Right now I'm looking at a page that has such promise and yet hasn't been touched since may '07; the beginnings of a course on how to Squeak. How did we let that die? How about fixing some of it? You know you want to. tim -- tim Rowledge; tim(a)rowledge.org; http://www.rowledge.org/tim Never write software that patronizes the user.

Fwd: [squeak-dev] OpenGL procedural textures generator (by David Faught) for Squeak 4.4
by Chris Muller 04 Aug '13

04 Aug '13

Reforwarding a message from last March which I cna't find in the archives.. > 100k?? ---------- Forwarded message ---------- From: Chris Muller <ma.chris.m(a)gmail.com> Date: Wed, Mar 6, 2013 at 4:44 PM Subject: Re: [squeak-dev] OpenGL procedural textures generator (by David Faught) for Squeak 4.4 To: Nikolay Suslov <nsuslovi(a)gmail.com> Cc: The general-purpose Squeak developers list < squeak-dev(a)lists.squeakfoundation.org> I attached a screenshot of debugger that occurs when I try to install it. There are a few interesting things to note: 1) The difference in the osVersion being checked for ('linux') vs. what mine is, ('linux-gnu'). This would cause the 'GL' option to be taken, is that right? 2) I don't understand why the debugger here -- the Message not being understood is for class BlockClosure and its selector is a single-character String of character 0. I can print the first line of code but restarting the method did not help, same error, so it appears to be a stack corruption of some kind.. ** Oh Wait ** -- So I just restarted the method and *stepped* through it, it correctly evaluated "Smalltalk osVersion = 'linux' and then it appears there is some kind of other hidden block or character in this method, see TweakCore-debugger2.png. At the bottom, that little blue square is the "highlight" and it blows up. So I simply removed that, resaved the method and proceed, and then I got "External Module not Found" and I was able to paste that stack (see below). So, trying one more time, I changed that method to eliminate the hidden character and also to compare to 'linux-gnu' but I still got a similar error. So I need to install something on my linux first? Sorry, I'm kind of a neophyte with this.. :) Thanks, Chris On Wed, Mar 6, 2013 at 5:11 AM, Nikolay Suslov <nsuslovi(a)gmail.com> wrote: > Chris, > > I have checked several times with loading TweakCore from SqueakMap and for > me it just works without any problems.

Frank, IIRC there's a null-character stuck in the source code of that method. I brought this to Nikolay's attention last March but it may not have gotten fixed. If you delete that character,at least you'll at least be able to step through that method...

OSProcess test failures on CI
by Frank Shearar 04 Aug '13

04 Aug '13

Hi Dave, A number of OSProcess tests fail on CI (http://build.squeak.org/job/ExternalPackages/287/#showFailuresLink). I'm installing them like this: Installer squeakmap update; addPackage: 'OSProcess (head)'; install. [(Smalltalk at: #AioEventHandler) aioPluginPresent] on: Warning do: [ "ignore the one-time warning dialog" ]. and I run the tests like this: HDTestReport runPackage: 'OSProcess-Tests'. which just runs the TestCases in that package using a custom runner. For instance, #testSpawnTenHeadlessChildren fails with "Block raised Warning: process accessor module not available". Could these be failing for the same reason the FFI tests fail? For instance FI.Tests.FFIPluginTests.testConstructedCharCall fails with "Unable to find function address". Any thoughts? frank
