This week on harmony-dev (Aug. 14 - Aug. 20 2005)

[David Tanzer <st...@guglhupf.net>]

Here's a copy of the http://deltalabs.at article about this week's 
discussion on harmony-dev. There is a RSS feed about harmony-related
articles at deltalabs: http://deltalabs.at/?q=taxonomy/term/8/0/feed

This week was very much discussion about the architecture of the virtual
machine, but there was some other things too. In the "call for
contributions" - Thread, Thorbjørn Ravn Andersen volunteered for writing
a native2ascii - replacement. Geir Magnusson Jr. updated the authorized
contributor questionnaire, it can be found here:

Weldon Washburn wants to more discussion about VM modularization on 
harmony-dev. He wants to concentrate on simple and stable interfaces
first, and leave the more complicated ones for later discussions. He
also suggested some interfaces and sub-categories for what he calls
"Class Support".

In the thread "[arch] VM/Classlibrary Interface (take 2)" there has been
some discussion on how different development groups have solved this 
problem. At the beginning of the week there where still licensing issues
to be resolved which prevented them from donating their interfaces, but
yesterday Weldon Washburn has asked Graeme Johnson and Tim Ellison to
post their interfaces to the wiki for further discussion. Tim will be on
vacation next week, so he will join the discussion when he's back.

Ricardo Morin has added a component diagram to the Harmony Architecture
wiki page (http://wiki.apache.org/harmony/HarmonyArchitecture):
http://wiki.apache.org/harmony-data/attachments/HarmonyArchitecture/attachments/ModularJVM.jpg
and this started the thread "[arch] Modular JVM component diagram". He
later added some more explanations about the diagram and the modules to
the wiki page.

Also in the "[arch] Modular JVM component diagram" thread, Torsten Curdt
asked for some mechanism in the VM to support native continuation in
java. Werner Schuster posted two links about continuation:
http://en.wikipedia.org/wiki/Continuation and
http://www.intertwingly.net/blog/2005/04/13/Continuations-for-Curmudgeons .
There was some more interesting suggestions on this topic by the two
authors mentioned above and some others, you can read the details in the
follow-ups to the original posting:

And again in the "[arch] Modular JVM component diagram" thread, Tom
started a discussion about using the "Apache Portable Runtime" (APR) as
our OS abstraction layer (OAL). After some discussion this seems to be a
good idea. Tom then suggested to "give our solution a little finer
granularity", i.e. to define the subset of the APR which is required to
get the VM to run.
