Re: [Pharo-project] ObjectScanner

by Mariano Martinez Peck

Seems to be used by SmartRefStream, but I don't know why. But it is easy to test it. This works: FileStream forceNewFileNamed: 'test' do: [ :stream | stream fileOutClass: nil andObject: 'something'. ]. (FileStream oldFileNamed: 'test') fileInObjectAndCode. Rename ObjectScanner, and you will get a compiler error. This is because it is being written in: SmartRefStream >> appendClassDefns The ObjectScanner class comment says: An instance of this class is the compiler's context for filing in a SmartRefStream containing instance-specific classes. When the old name of a new object's class conflicts with an existing class name, install a class var in me. It has the old name but points at the new class. The compiler uses it when compiling the code in the fileIn. Fill the SmartRefStream's renamed class dictionary. An object fileout: !ObjectScanner new initialize! "allow me to take control with scanFrom:" Player subclass: Player23 instanceVariableNames: 'foo' classVariableNames: '' poolDictionaries: nil category: 'Instance Specific'! "I prescan this and (self rename: #Player23 toBe: #Player30)" !Player23 methodsFor: 'all' stamp: 'tk 3/9/98 18:58'! "actually sent to Player30" foo ^ foo! ! !self smartRefStream!<binary representation of the objects>!

If you have a 64 bit operating system than you can only execute 64 bit executables. In linux there are 32 bit compatibility libraries. The offer a 32 bit interface and mediate this to 64 bit. So you can run a 32 bit vm with compat libraries or native 64 bit vm. The same goes for code that you want to link to the vm. It needs to fit. What the vm internally uses for its address space does not depend on this. I think that is confusing for a lot of people that you can have a 64 bit vm with a 32 bit image. But does anyone know what is the state of 64 bit vm executables? Norbert
