[Pharo-project] Are objects moved (changed the address in memory)?

by Mariano Martinez Peck

Hi. Nebwie here. THe first question is if objects are moved (changed the address in memory) at runtime? I am 99% sure the answer is true. If so: 1) Who moves them ? the GC? 2) when ? agains which events, what triggers these movements? 3) why they are moved? to compact the memory ? why the memory needs to be compact? for arrays? 4) Is there a way to say "please, don't move this object X" ? what would be the problem of having a lot of these "non-moveable" objects? memory fragmentation ? If you can point me to the code also I would be happy. Thank you very much in advance, Mariano

Not only merge the files; I want too do a wizard for configure the state of image, what maybe launched when the image is startup or down (with events), change the default error messages, without debug option, or try shrink the image of not needed packages etc, and finally select the output for windows, OSX etc . Something like that exists on VisualWorks. I donÂ´t know if is possible do all that, and I need know if exists some previous work.

For windows you can use a windows installer like this one: http://gforge.inria.fr/frs/download.php/26835/setup_pharo1.0-10517-release1… Maybe this is helpful: http://code.google.com/p/pharo/wiki/HowToDeployAnApplication http://squeakvm.org/win32/custom.html cheer mariano On Mon, Jul 19, 2010 at 2:35 PM, StÃ©phane Ducasse <stephane.ducasse(a)inria.fr > wrote: > > On Jul 19, 2010, at 10:39 AM, nullPointer wrote: > > > > > Excuse me for my poor english. > > > > I want implement a mechanism of deploy in Pharo.

Re: [Pharo-project] [Vm-dev] how to identify objects ? (hash?)

by Adrian Lienhard

Hi Mariano, What I suggest as a solution is to store an array of your objects in memory and in the file you refer to objects through indices into this array.
