Re: [Pharo-project] Incremental garbage collection

by John M McIntosh

http://www.smalltalkconsulting.com/papers/GCPaper/GCTalk%202001.htm see slides 46 & 47 You need to have a tenure event, or a full GC to move the youngStart pointer past all previously allocated objects, thus promoting a previously allocated object from new space into old space. There is btw a primitive I added many years back primitiveForceTenure SystemDictionary>>forceTenure Understanding when and why you would want to use it is another question...

Sorry for the infinite loop, it was my fault. I thought it had been detected and solved already (in squeak ?). Destroying source pointer of un-installed methods was just a workaround to be used in case of already broken sources. There is another strategy : detect the source pointer of un-installed methods and store them in the new change log. This has to be done before logging source code of installed methods.

Its quite sophisticated, and having a lot of quirks & preconditions. But after compaction (either incremental or full), it usually picks a free memory region which will serve as a space for newly created objects.

I am still newbie with VM stuff, but as I understood, yes, young objects become old when they survive to thei first incremental GC. Notice the INCREMENTAL GC and not FULL GC. But I may be wrong...so I will let other to answer properly ;) I have just looked at the code and I am not sure where that movement happens :( Cheers Mariano > Cheers, > Alexandre > > -- > _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: > Alexandre Bergel http://www.bergel.eu > ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;. > > > > > > > _______________________________________________ > Pharo-project mailing list > Pharo-project(a)lists.gforge.inria.fr > http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-project >
