[Harmony Wiki] Update of "Google Summer Of Code 2008 Projects Proposals" by
XiaoFeng Li
Dear Wiki user,
You have subscribed to a wiki page or wiki category on "Harmony Wiki" for change notification.
The following page has been changed by XiaoFeng Li:
http://wiki.apache.org/harmony/Google_Summer_Of_Code_2008_Projects_Proposals
New page:

#language en
(Please add your proposals in the list)
== Google Summer Of Code 2008 Projects Proposals ==
1. '''Implement the "Compressor" GC proposed by Kermany and Petrank'''.[[BR]]
The Compressor garbage collector [1] is a compacting GC that leverages virtual memory support in underlying OS. It compacts the heap in two passes. [[BR]]
[1] Haim Kermany, Erez Petrank: ''The Compressor: concurrent, incremental, and parallel compaction''. PLDI 2006.
2. '''Implement the "Mapping Collector" proposed by Wegiel and Krintz'''.[[BR]]
The Mapping Collector [2] utilizes the virtual memory support in a novel way so that it can compact the heap without moving the objects or fixing the references.[[BR]]
[2] Michal Wegiel and Chandra Krintz, ''The Mapping Collector: Virtual Memory Support for Generational, Parallel, and Concurrent Compaction'', ASPLOS 2008.
3. '''Write a graphic font-end for Harmony memory management'''.[[BR]]
Harmony runtime needs a graphic front-end visualizing the memory management activities and the runtime status. It can be standalone or better an Eclipse plugin. It can be online display of the runtime execution, or offline processing of the log.
4. '''Unify the native memory management of Harmony DRLVM'''.[[BR]]
DRLVM uses inconsistent APIs for native memory management, such as APR or malloc or mmap. It is desirable to have a unified API for native memory management. Hopefully the runtime native memory usage can be managed with a global view and then optimized. This layer could be extended to provide the API for Java heap native management as well.

That's good news! I must have missed those JIRAs/announcements. Do you
know if any others have been started? To me the list looks like this,
although I may have missed some more:
apt
extcheck
HtmlConvertor
idlj
jar
javaws
jconsole
jdwp
jdmpview
native2ascii
policytool
rmic
rmid
rmiregistry
serialver
tnameserv

Hello Sian,
With respect to javadoc, may be doxygen is sufficient. I also have
noticed some ongoing development in appletviewer area [1] and javap
contribution [2]. May be we may omit these tools from the task.

Egor,
I have added the tasks. Thanks for pinging me.

I've added a task too for implementing one of the jdk tools.

Very cool! Need to make a sexy task so that students are perfectly

Hello Egor,
I may mentor a student on archive module clean up: I have left four
TODO comments after my changes. Also, I tried to implement drag and
drop, but lacked something (guts?). I would be happy to teach a
student in areas I know if he feels himself suited for this task.
Finally, FreeCol fails due to some AWT functionality [1]. This might
be an interesting goal to enable FreeCol on Harmony.
Thanks.

Thanks, xiaofeng!
I added mine.
I wonder, does anybody want to mentor a student on a classlib task?
For example, implementation of the uniplemented. imageio? awt? swing.text?

Hi,
I would very much like the Jikes RVM to be working with the Harmony
class libraries. I have a JIRA tracker [1] and entry in to what are the
current Jikes RVM GSoC project proposals [2]. I would be interested in
hearing from people who would like to help mentor such a project? I
wonder if it might also be listed on the Harmony project list? I would
be happy to help mentor it as a harmony GSoC project.
Many thanks,
Ian Rogers
