Hello all I am trying to do a research on Manual Memory Management and Automatic Garbage Collection on Ruby.So i need to play with Garbage Collector code of Ruby.I am using Ruby 1.8.6 I am also trying to figure out in Ruby when the Garbage Collector starts working.But didn't got any clue. I read somewhere in wiki about some systems that uses this design of Memory Allocation. Can any one help me in some of my queries:- 1. When the Garbage Collector starts working can I see it.(For e.g-It will print like Garbage Collector starting.)Somebody referred me use GC_NOTIFY but there is no such function in the gc.c file. 2. What are the main parts in Ruby Garbage Collector I need to know to accomplish this research. After I get my first step done I hope I will have many questions to share with you all.
