[jira] Created: (HARMONY-2560) Finalizer and weak reference for
GCv5
Finalizer and weak reference for GCv5
-------------------------------------
Key: HARMONY-2560
URL: http://issues.apache.org/jira/browse/HARMONY-2560
Project: Harmony
Issue Type: Improvement
Components: DRLVM
Environment: Windows and Linux 32-bit
Reporter: Li-Gang Wang
Attachments: finalizer_weakref_for_GCv5_20061210.patch
This patch implements finalizer and weak reference functions for GCv5.
The finalizer threads are implemented as native threads. And weak reference enqueueing is also executed in a native thread. But these features will not affect the present implementation at all. They are only used for GCv5.
To apply this patch, please firstly apply this patch:
https://issues.apache.org/jira/browse/HARMONY-2509
Then enter "drlvm/trunk", "patch -p1 < finalizer_weakref_for_GCv5_20061210.patch"
Files added in this patch include:
drlvm/trunk/vm/vmcore/include/finalizer_thread.h
drlvm/trunk/vm/vmcore/include/ref_enqueue_thread.h

[jira] Commented: (HARMONY-2560) Finalizer and weak reference for
GCv5
Posted by "Pavel Afremov (JIRA)" <ji...@apache.org>.
[ http://issues.apache.org/jira/browse/HARMONY-2560?page=comments#action_12457287 ]
Pavel Afremov commented on HARMONY-2560:
----------------------------------------
Hi I have several questions about finalizer & ref in vm part.
1. For what reason is native finalizer thread required? I thought that native and java threads is equal for finalization purpose. Also Java thread can uses future "magic" technology for extra performance.
2. Finalizer thread starts works with highest priority, doesn't it? Is it right? Why VM should stops when any finalization works is required?
3. In Finalization system now there is Work Balance Mechanism which tunes performance of finalization. When many finalizable object are allocated and queue for finalization isn't empty this mechanism increase performance of finalization (more detailed description see in dev guide). I can't found usage of Work Balance Subsystem in this patch. Maybe it would be better to use WBS instead high priority forever for finalizer thread.
4. Did you check you patch with gc.SynchronizedFinalizerTest? Could play with parameters in this synthetic stress test to provide reliability of finalization system for any work load.
Thank you in advance
Pavel Afremov.
