[Pharo-project] A port of Pharo: Redline Smalltalk ...
by James Ladd May 28, 2010

May 28, 2010

Hi Pharo-ites, I'm working on a port of Pharo to the Java Virtual Machine called Redline Smalltalk. (read more here: http://jamesladdcode.com/?p=323) I'm wanting to port every single class over time, but initially enough to get the compiler working and have a minimum runtime. Of the 1600+/- classes which are those necessary to make a small workable compiler and runtime environment? Rgs, James. _________________________________________________________________ Need a new place to live? Find it on Domain.com.au http://clk.atdmt.com/NMN/go/157631292/direct/01/

Re: [Pharo-project] [squeak-dev] Re: New weak finalization support. Implementation
by Igor Stasenko May 28, 2010

May 28, 2010

Guys, it looks like i found an elegant solution. Please check the new-finalization-auto.2.cs, which i uploaded to http://bugs.squeak.org/view.php?id=7473. It adds just a few things: initTestPair TestItem := WeakFinalizerItem new list: TestList object: Object new. checkTestPair HasNewFinalization := TestList swapWithNil notNil. These two method is then sent from within WeakArray's finalization process: finalizationProcess [true] whileTrue: [ WeakFinalizationRegistry initTestPair. FinalizationSemaphore wait. FinalizationLock critical: [ WeakFinalizationRegistry checkTestPair. FinalizationDependents do: [:weakDependent | weakDependent ifNotNil: [weakDependent finalizeValues]]] ifError: [:msg :rcvr | rcvr error: msg]. ]. And so, at each GC cycle, a new registry it knows exactly if it allowed to do a shortcut, or not. And if not, then it behaves in same way as old registry - it starts scanning the whole dictionary to clean graveyard. So, in summary: running on older VMs , a WeakFinalizationRegistry will behave exactly as old WeakRegistry. While on VMs, which supporting new finalization, it will do a shortcut. This is at cost of extra 2 objects, allocated per GC cycle, to detect if new finalization is supported. P.S. oops, actually it could be just one object.. just need to change two methods at WeakFinalizationRegistry class side: initialize TestList := WeakFinalizationList new. TestItem := WeakFinalizerItem new. initTestPair TestList swapWithNil. "make sure list is empty" TestItem list: TestList object: Object new. -- Best regards, Igor Stasenko AKA sig.

[Pharo-project] Struct with doubles
by Schwab,Wilhelm K May 27, 2010

May 27, 2010

Hello all, I am faced with some win32 software that uses a structure like struct gizmo { double x; y; z; double q[4]; } Would it be legal to treat that as struct gizmo { double x; y; z; double q0; q1; q2; q3; } and then let Pharo define the fields? This is running on 32 bit winxp. A colleague is doing 3D magic with the resulting numbers, but Weird things appear to be happening. I am looking for ways that I might be causing them. It is also possible that the gizmo to which we are interfacing is just plain broken. Bill

[Pharo-project] Integrating VMMaker-dtl.175
by Igor Stasenko May 27, 2010

May 27, 2010

Dear all, i would really like to finish an integration of new finalization. But this requires releasing a new VMs for all platforms. If you think, we're done with VM-side part, then lets proceed with releasing new VMs, so we could start using new feature. -- Best regards, Igor Stasenko AKA sig.
