1. GC Algorithm inside .NET Luo Bingqiao 5/22/2009

2. Agenda 经典基本垃圾回收算法 CLR中垃圾回收算法介绍 SSCLI中Garbage Collection源码分析

3. 经典基本垃圾回收算法 Reference Counting算法 Mark-Sweep与Mark-Sweep-Compact算法 Copying 算法

5. Deferred reference counting

6. One-bit reference counting

9. At some stage, mark the objects that are dead and can be removed

11. Every allocation request requires a walk thru the free list, makes allocations slow

13. Allocate only from one heap

14. When collection is triggered on the heap, copy all alive objects to the second heap

16. Copy operation needs to be done for all objects

19. Generational incremental Collector

20. Large Object Heap

21. Segments

22. Finalization in CLR

23. Weak References

24. Pinning

26. Overall of GC Algorithm

27. Mark Phase:

29. Finalizable objects are put on the FReachable queue

30. Weak pointers to dead objects are nulled

32. Managed Heap after Compact:

33. Finalization Internals
