Smalltalk meetup in Berlin on June 12
by Bert Freudenberg 11 May '17

11 May '17

Hi all, this week Nikolas Martens (https://twitter.com/rtens_) gave a presentation about Smalltalk at a Softwerkskammer Berlin event. He live-coded a TicTacToe game twice (in Morphic and Seaside). There was a lot of interest in coming together more often to discuss Smalltalk and related technologies so he set up a "kick-off" meeting for the "Object Group Berlin" on Monday, June 12. If you are interested in attending, please RSVP at https://www.meetup.com/Object-Group-Berlin/events/239818819/ Also, please share :) - Bert -

WorldMorph subclass: PasteUpMorph?
by K K Subbu 10 May '17

10 May '17

Hi, Is there any specific reason why WorldMorph is not a subclass of PasteUpMorph? The latter uses a variable to hold significant world state and rest of Morphic use isWorldMorph to check the type before calling methods. I would have expected subclassing and double-dispatch to yield smaller and cleaner code. Regards .. Subbu

Marcel Taeumel uploaded a new version of Morphic to project The Trunk: http://source.squeak.org/trunk/Morphic-mt.1336.mcz ==================== Summary ==================== Name: Morphic-mt.1336 Author: mt Time: 10 May 2017, 10:13:26.142647 am UUID: 4d60356c-2429-724c-9d45-4fe22cd330fc Ancestors: Morphic-ul.1335 Quick fix to avoid accidential drops of system windows into the world main docking bar. Actually, we should think about the necessity of having the preference #systemWindowEmbedOK, which is set to "true" in current images. Setting that preference to "false" would have also solved the issue but committing state (other than code) via Monticello is cumbersome. I think that that preference origins from the time when we could manage worlds in worlds and also MVC windows having Morphic worlds. Much of that code was removed in the course of clean-up since MVC and Morphic are quite different in their basic event processing and drawing methods. =============== Diff against Morphic-ul.1335 =============== Item was changed: ----- Method: SystemWindow>>wantsToBeDroppedInto: (in category 'events') ----- wantsToBeDroppedInto: aMorph "Return true if it's okay to drop the receiver into aMorph" + ^ (aMorph isWorldMorph or:[Preferences systemWindowEmbedOK]) + and: [aMorph isDockingBar not]! - ^aMorph isWorldMorph or:[Preferences systemWindowEmbedOK]!

Hi, (this did not seem to make it the first time) I'm the one who volunteered to take over for planet squeak. I'm traveling right now, but, this weekend or so I'll get a chance to see how to move it.

Error in ImageSegment primitive?
by Max Leske 09 May '17

09 May '17

Hi, I'm trying to store an image segment with the latest pharo.cog.spur VM (32 bits) but keep failing. The segment should produce a file of around 60 MB. With an old V3 VM this is no problem at all. There, the WordArrayForSegment instance has a size of 4094179 but with the new VM I always run out of space because the primitive returns nil and, therefore, the word array size is constantly being increased. I've built a debug VM and am stepping through the code but I don't have a clear understanding of everything that's happening. The failure happens on line 46626 of gcc3x-cointerp.c: newOop = (copy - segStart) / 8; if (newOop > (identityHashHalfWordMask())) { return PrimErrLimitExceeded; // <--------------- failure } What I don't understand, for example, is why "newOop" is checked against "identityHashHalfWordMask()" and not against the segment end ("endSeg"). Here's a list of the current values of the variables upon failure: objOop sqInt 180812096 segAddr sqInt 494731288 segStart sqInt 461176856 endSeg sqInt 815841432 bodySize usqInt 64 contextSize sqInt 335672448 copy sqInt 494731288 hash sqInt 0 hash1 sqInt 4194302 i sqInt 833574680 iLimiT sqInt 833574688 methodHeader sqInt 1193471 newOop sqInt 4194304 numMediatedSlots sqInt 833574688 numSlots usqInt 14 oop sqInt 142640272 As you can see, "endSeg" would be more than large enough to hold the object. Is it possible that there's an error here? Cheers, Max

Downloading from binary via curl
