Re: [Pharo-project] new Cog VMs

by Eliot Miranda

Hi All, there are new versions of both the SimpleStackBasedCogit and the StackToRegisterMappingCogit Cog VMs in VM.r2339/<http://www.mirandabanda.org/files/Cog/VM/VM.r2339/> & VM.r2340/ <http://www.mirandabanda.org/files/Cog/VM/VM.r2340/> respectively. These contain fixes for rounding bug causing underestimate of openPICSize and resultant hard crashes, seen e.g. by trying to recover lost changes in a Pharo 1.2 image installed on c:\pharo. If you're trying to reproduce Cog crashes please upgrade to one of tthese two VMs. TIA Eliot On Thu, Dec 30, 2010 at 6:02 PM, Eliot Miranda <eliot.miranda(a)gmail.com>wrote: > Hi All, > > I've released a new version of Cog that has a substantially improved > code generator along the lines of Peter Deutsch's HPS (VisualWorks) and > various of Ian Piumarta's VMs. These all use a simple tecnique to identify > constant references in bytecode and to support a register-based calling > convention.

Re: [Pharo-project] Issue 3436 in pharo: #copyFrom: is broken

by pharo＠googlecode.com

Comment #5 on issue 3436 by rydier: #copyFrom: is broken http://code.google.com/p/pharo/issues/detail?id=3436 If we end up deprecating and reimplementing, at least make the "new" implementation in SequenceableCollection, where it can be found in STX and GnuST. I still don't think it's a good idea to add to the SequenceableCollection API though, because: - It's not ANSI (VW for instance does not have it) - There is already copyFrom:to: and allButFirst: filling the same role nearly as easy - It'll break code for no better reason than to increase readability (unless you actually look up its implementation, in which case it's quite clear what it does) - There's yet another point of difference if you want to have your code running on both Squeak and Pharo

Running the TraitsTestCase also works w/o problems. This bug is really lurky SOAB :) I removed the TraitCompositionTest from system and run the tests again.

This is reproducible by running: FileStreamTest run: #testReadIntoStartingAtCountAll but works fine in older VM(s). I continued attempts to run whole tests after removing TraitCompositionTest and FileStreamTest, and here's another one: (gdb) bt #0 0x00040bb7 in mapPointersInObjectsFromto (memStart=455419144, memEnd=456751028) at sqMemoryAccess.h:81 #1 0x00043acc in becomewithtwoWaycopyHash (array1=456751008, array2=456751016, twoWayFlag=1, copyHashFlag=1) at /Users/sig/projects/cog/sig-cog/src/vm/gcc3x-cointerp.c:9410 #2 0x00044268 in primitiveArrayBecome () at /Users/sig/projects/cog/sig-cog/src/vm/gcc3x-cointerp.c:22887 #3 0x19dc8c31 in ??

Another thing which i noticed that i got DNU during world menu render and it is caused by making colors of Cubic-Rubik form to contain smallinteger values. This is original (once i start image): ColorForm allInstances collect: #colors an Array(a ColorArray(Color transparent (Color r: 0.0 g: 0.0 b: 0.004)) a ColorArray(Color transparent Color transparent) a ColorArray(Color transparent Color transparent)) And after some manipulations and wandering i got: ColorForm allInstances collect: #colors an Array(a ColorArray(Color transparent (Color r: 0.0 g: 0.0 b: 0.004)) a ColorArray(Color transparent Color transparent) a ColorArray(Color transparent Color transparent) #(0 4278190081)) What i found really strange that these values are somehow flipped back to normal ones (or maybe it is i, who restarted the image.. not sure).. -- Best regards, Igor Stasenko AKA sig.
