WriteBarrier should work just fine with Magma as long as you don't change class definitions while connected to a repository. Regrettably, objects behind a WriteBarrier cannot handle a class-schema upgrade under certain conditions, but this has nothing to do with Magma.. If you have found an issue with Magma, I would be happy to fix it. - Chris

[BUG] positionOfSubCollection:
by Avi Bryant 05 Jul '05

05 Jul '05

'ab' readStream positionOfSubCollection: 'ab' "1 OK" 'aab' readStream positionOfSubCollection: 'ab' "0 WRONG" What's going on here is that positionOfSubCollection: is apparently being very naive: "is 'aa' = 'ab'? No. Ok, is 'b' = 'ab'? No. Ok, 'aab' must not have 'ab' then.". This is likely to cause problems in all kinds of places, but the specific place I ran into it was trying to upload a file ending in a CR to Comanche - it ends up looking for CRLF in CRCRLF with exactly the same results as the 'aab' example above. Rather than trying to figure out how to fix this method, since it's only used by SocketStream, I thought I'd try out Göran's FastSocketStream instead. That solved the problem nicely. Incidentally, the initials on the latest #positionOfSubCollection:ifAbsent: are mine, because of a fix I submitted last December. I don't think this fix caused the problem above (it was just for an off-by-one error), but I don't have the earlier version handy, so I can't be sure. I also don't remember who the original author was, but perhaps they have some insight... I'm posting this to the list rather than just to Mantis to a) warn people that they might want to use FastSocketStream if they're having trouble with HTTP uploads and b) ask, is there any reason we aren't looking at including FastSocketStream as the default SocketStream implementation in the image? Göran, do you think it's ready, or are there still kinks to work out? Avi

AW: Commercial Smalltalks deserve our support too (Was: www.squeak.org finally updated)
by Nowak, Helge 05 Jul '05

05 Jul '05

which means we need more universities and other academic/educational organisations to teach Smalltalk and use Smalltalk in research, be it Squeak or any commercial dialect -- should I point to Cincom's Academic Program here ? ;-) -----Ursprüngliche Nachricht----- Von: John Pfersich [mailto:jp1660@att.net] Gesendet: Dienstag, 5. Juli 2005 04:15 An: The general-purpose Squeak developers list; vwnc(a)cs.uiuc.edu Betreff: Re: Commercial Smalltalks deserve our support too (Was: www.squeak.org finally updated) I biggest problem that I see with the Smalltalk is the apparent lack of Smalltalk "programmers", not the competition between the various Smalltalks.

I just went in and made a number of these changes - I hope the website team doesn't mind, but if they do, hey, that's why it's a wiki... I also did a little cleanup of English grammar and usage, but there's still more that could be done there. I don't mind doing another pass at that later. The front page does feel a little short and empty now, though. We may want to have a "featured project" or something rather than just the list of "hot sites". Avi

Hi Stephane, I most definitely am interested in getting bug reports or comments on our LookEnhancements. I will remedy as soon as practical.

squeak using high CPU, reporting little use
by Ross Boylan 05 Jul '05

05 Jul '05

squeak gets in this odd state where it consumes lots of cpu according to the operating system tools, but when I do a debug message tally it reports over 90% of the time in idle. Doing a save always clears up the problem (perhaps because of a global garbage collect?). Smalltalk vmVersion gives 'Squeak3.8gamma of ''24 November 2004'' [latest update: #6548]' Running on linux with a largish image (57Mg). The image itself is a bit old, with #4956 the last update; I think that makes it 3.6 era. Any ideas what's going on?
