Hi Xiao-Feng,
Thanks for these questions. I believe that they'd be really helpful in
understanding VM <-> GC assumptions on the Parrot end.
Will work on answering these, and perhaps a comparison with Harmony.

Hi Alexei,
My thought was to match each and every portion of API that Parrot would
expose to a external party. So, at the moment, I believe that everything in
dod.h might not necessarily be external API. So perhaps I should categorize
the document in to two sections. I have also mailed the link to

Senaka, thanks for the page. I think the most important things are
related to the VM <-> GC protocol. Some questions that may help you:
1. How Parrot layout/encode an object/array? fields, size, object
header info, etc.
2. How Parrot layout/arrange the heap? free list? pages?
3. What's the process
It's broken for me too. Sian? Andrew?

Good job, Senaka.
The general perception was that internal and external GC interfaces

Senaka,
This is a good question.
Harmony GC interface does not allow freeing objects. From the other
side if JIT is able to determine boundaries of the object life cycle
and bound them to a stack, it allocates objects on the stack, so they
are freed automatically. This is called escape analysis an

Hi all,
Can you explicitly free an object without calling the GC? It seems that
Parrot's GC interface exposes methods to free a specific object instead of
getting the GC to collect it. Does Harmony have something similar?

Hi all,
I have almost finished comparing the two interfaces of Harmony and Parrot.
However, I'm not 100% sure on whether I got everything right, but I believe
that most of it is. Therefore, it would be really great if you could review
the wiki page and let me know whether it is correct and precise

Great news, Kostya! I am eager to see how it works ;)

Yes, I think COW is not mandatory for Parrot. Thanks, -xiaofeng

Hi Xiao-Feng, Alexei,
Thanks for the update. I'm not 100% aware of the usefulness of COW beyond
the scope of the Parrot VM, since this is a VM, the usefulness of COW would
depend on the upper layers that use it. Thus, perhaps when thinking about
uses of Parrot, and as we are interested in plugging
Harmony GC doesn't have COW support (at the moment). COW can help to
reduce the footprint when multiple processes are forked sharing data.
It's not useful for Java (at the moment) because Java uses threads
mostly. Before we have real needs (workloads) for COW, we are not
able to give an appropriat

Hi Alexei,
This issue came up when I was trying to match interfaces of Harmony GC_Gen
and Parrot. It seems that the Parrot GC is aware on whether COW is used.
ex:- clear_cow, used_cow in dod.h
It seems that it maintains a COW ref count etc.

Hello Senaka,
Copy-on-write semantics is used for native strings, see unistr.h If GC
would use copy-on-write, this would be rather implementation than
interface. Why do you need this info?
