New, faster RISC OS Squeak
by tim Rowledge 07 Feb '13

07 Feb '13

I know there are many of you that are just waiting with bated breath for a faster RISC OS Squeak; well now you can stop turning that unattractive shade of blue. I found a spot where a stupid amount of time was being wasted in the UI, fixed it and hey presto! A dramatic improvement in Morphic UI performance. No longer does typing drag horribly. No more do menus take a coffee break to appear. http://www.rowledge.org/tim/squeak/Squeak3-9d-RISCOS.zip As an aside - and talking of stupidly wasted time in the VM- it turns out that around 20% of the entire time is spent handling the insane nonsense of converting old-style Mac OS pixels into proper RISC OS pixels. Are x86 machines afflicted the same way? Maybe the fast graphics cards are able to mask the time taken, but I'm pretty sure they're spending some time on the job. tim -- tim Rowledge; tim(a)rowledge.org; http://www.rowledge.org/tim Strange OpCodes: HEM: Hide Evidence of Malfunction

However, Scratch (and possibly other applications) makes use of direct sensor access from Morphic (arguably this is an error in Scratch, but the usage exists nonetheless). I don't think it's at all arguable; Scratch appears to be spending near to 10% of its time (on a 3GHz iMac!) checking inappropriately for input events. I guess that's v2.8 Morphic for you... tim -- tim Rowledge; tim(a)rowledge.org; http://www.rowledge.org/tim Strange OpCodes: HALT: No-Op

The Trunk: Kernel-dtl.733.mcz
by commits＠source.squeak.org 07 Feb '13

David T. Lewis uploaded a new version of Kernel to project The Trunk: http://source.squeak.org/trunk/Kernel-dtl.733.mcz ==================== Summary ==================== Name: Kernel-dtl.733 Author: dtl Time: 6 February 2013, 9:02:02.046 pm UUID: b74ab5eb-4f9f-4f1a-bf6d-90f8f60fb3c4 Ancestors: Kernel-eem.732 Remove EventSensor>>wait2ms Use of EventSensor>>wait2ms in sensor direct access to mouse and keyboard causes slow and incorrect keyboard handling in MVC. In newer Squeak images (3.9 and later), removing the delay restores normal MVC keyboard input. This change removes the wait2ms delay entirely. If the problem described in http://lists.squeakfoundation.org/pipermail/squeak-dev/2007-May/116185.html should reappear, a different solution will be required. Notes: In Squeak trunk, the wait2ms delay is invoked only when in MVC. However, Scratch (and possibly other applications) makes use of direct sensor access from Morphic (arguably this is an error in Scratch, but the usage exists nonetheless). Background: Recent thread in which Stéphane Rollandin identified the source of the problem: http://lists.squeakfoundation.org/pipermail/squeak-dev/2013-February/168526… Rationale for introducing the delay in earlier versions of Squeak: http://lists.squeakfoundation.org/pipermail/squeak-dev/2007-May/116185.html =============== Diff against Kernel-eem.732 =============== Item was changed: ----- Method: EventSensor>>peekButtons (in category 'accessing') ----- peekButtons - self wait2ms. self fetchMoreEvents. ^mouseButtons!

new Cog VMs available
by Eliot Miranda 06 Feb '13

06 Feb '13

http://www.mirandabanda.org/files/Cog/VM/VM.r2678 CogVM binaries as per VMMaker.oscog-eem.264/r2678. Fix snapshot primitive failure in the StackVM and Cogit. The primitive should fail, not merely return the receiver. Also if in Cogit, need to back-up instruction pointer on failure. Make reportMinimumUnusedHeadroom more informative (also print available headroom). -- best, Eliot
