Hi..About Gsoc 2009 project ideas...

Hi,

I'm an Computer Science Undergraduate who is currently undergoing training
and engaged n the field of Open Source SOA products n development. I've
recently done project work in the area of WS Security (WS [Web Services]
Policy derivation from SOAP messages n some OSGI component[WSO2 Carbon
platform] implementatons around that..) and have some knowlege on WS
security implementations.

Also i've recently been working on deploying Ruby
Services on Apache Axis2 Engine using JRuby frame work..I Would really like
to participate in a Ruby project for GSoc 2009 n would like to have some
project ideas to be heard from Ruby people..One of the things i'm really
interested in doing is to develop a Ruby Annotation framework
(DSL/parser)for a given spec as ruby currently doesn't support this behavior
very well. For my opinion this will be really important for WebServices and
related stuff as i my self has come across difficulties in not being able
to use a proper annotation framework as available in Java or C++. I'm still
pretty much new to ruby n it's aspects and hence doesn't know how feasible
this is or the scope of this n really appreciate if you all could enlighten
me on this . Also i'm open to other project ideas as well and again
appreciate your kind reponse. Thnx in advance..

Thnx,
Udayanga Shaminda Wickramasinghe

Hi,
Just thought of asking about how the things are going on with 2009 GSoc
project proposals for Ruby .However i'm not too sure whether this is the
exact mail list ,where new ideas should be discussed regarding GSoc 09. If
someone has an idea please provide me with your kind feed back. I would
really appreciate your thoughts regarding my previous mail as well , if
possible. Thnx in advance...

Actually, instead of posting off on the urug list, I'd still recommend
discussing it here (or in a ruby brigade list/meeting closer to your
home).

Hi,
Thnx Roger for your kind suggestion. However Pat Eyler suggested me to po= st
my idea here when i first contacted him. Neverthless i'll post my request
there =A0as well. Thnx again for your feedback..
Regards ,

me on this . Also i'm open to other project ideas as well and again

appreciate your kind reponse. Thnx in advance..

If you just want ideas here are a few [or anybody else can contribute
ideas if you've thought of something once that you would put a bounty
our for].

1) mod_rails: integrate jruby with it somehow. Beef it up with a few of
its most starred wish list items [1]. My own favorite would be Make
RailsMaxPoolSize Vhost than Global

2) experiment with the MRI garbage collector, see what settings are good
with what, create getters/setters for it [2]. Could profile it with the
Ruby Benchmark Suite [3].

3) Try to optimize rails. I.e. look for bottlenecks and try and clear
them up with quality LRU cacheing or prepared statements or something

4) ruby 1.9 quality debugger. ruby-debug is currently only 1.8.x compat,
I believe. I'm actually not sure if this is totally possible, but some
parts of it are probably 1.9 compatible.

5) "pie in the sky" psyco for ruby implement an LLVM JIT for Ruby.

Speaking of which I wish that the Google Summer of Code people somehow
were more transparent--like they had to post a result of their work to
at least ruby talk or something.

Cheers!

~/projects/jruby =E2=9E=94 jruby --jdb test.rb
Initializing jdb ...

stop at test:1

Deferring breakpoint test:1.
It will be set after the class is loaded.

run

run org.jruby.Main test.rb
Set uncaught java.lang.Throwable
Set deferred uncaught java.lang.ThrowableVM Started: Set deferred breakpoint test:1

Breakpoint hit: "thread=3Dmain", test.__file__(), line=3D1 bci=3D12

main[1] list

2 puts 2
3 puts 3
main[1]

5) "pie in the sky" psyco for ruby implement an LLVM JIT for Ruby.

I wonder if you could do this for Rubinius, too.

I wonder if you could do this for Rubinius, too.

Actually right now the closest thing to a fully functional JIT for Ruby
is JRuby. We run almost all Ruby code and tests out there, and after
compiling to Java bytecode the JVM takes that and turns it into native code.

So the lesson is: if you want a native-jitting Ruby impl to run your
apps...use JRuby

Hi,

Firstly i would like to thank Pat, Roger and Oliver for your kind thoughts
on Gsoc Ideas.
Regarding the ideas,

i like the ideas of integrating jruby with mod_rails , and ruby 1.9
debugger, but i need to go into more detail of the problem as i do not have
clear cut understanding of these scenarios(especially about Phusion
Passenger). If anyone has a JIRA link or blog post or any other link pls be
kind enough to post here..Obviously i'll have to do some research as well as
i'm still pretty much new to ruby and it's frameworks..

Also i would like to know any suggestions/views on ruby annotation
framework that i have previously mentioned.
I don't know how exactly Gsoc ideas are being put up for Ruby.. whether do
we have to contact Ruby Central or they'll be selecting prospective ideas
given by ruby community. I would really appreciate if anyone could enlighten
me on the above . Thnx again for the thoughts you have rendered.

Best Regards
-Udayanga

here's a link to some mod_rails stuffs:

re: 1.9 debugger not sure. Looks like it might be hard.

what do you mean by annotation framework?

Cheers!
-=r

 

[Roger Pack]

project ideas to be heard from Ruby people..One of the things i'm really
interested in doing is to develop a Ruby Annotation framework
(DSL/parser)for a given spec as ruby currently doesn't support this
behavior

Another few ideas would be:

porting java's testng to ruby [or would that be useful--I suppose
test/unit and minitest are pretty good]

porting python's process module to ruby. Perhaps using the python apr
to get cross platform goodness.

Thoughts?

me on the above . Thnx again for the thoughts you have rendered.

We'll be posting a page of ideas, but encourage students to consider
their own ideas as well. Student proposals will be accepted through
the GSoC web site:
http://code.google.com/soc/
You might want to look at the FAQ:

Thnx Roger further enlightening us with your prospective ideas for Ruby
And Thank you Pat for the information you have mentioned , i'll constantly
poll for new developments with the links you have provided .

And Roger about the annotation framework ...I find it really useful for web
services and stuff (like testng tools,etc) the presence of a proper
annotaion framework ,as it will provide ways and means to declare some
meta-data needed for these programmes (such as schema definitions ,test
criterias,etc) , in the programme itself rather than going for external
descriptors and stuff . In java we get java.lang.annotation framework (and
various other adhoc annotation schemas ) where use of @ is extensively used
as annotation syntax (ie:- @depricated ==> for javadoc stuff , @interface
=>custom type declerations, etc) .

In java you also get seperate annotation processing tools[Like Annogen] ,
varoious annotation API's, etc to support these annotaion specifications .
However in Ruby i didn come accross such a framework for
specifying/processing annoations and its purely my assumption that ruby
currently doesn't support such behavior (if i'm wrong pls some one enlighten
me on this ) . I'm no annotaion frameworks geek , bt would really like
suggest this as a Gsoc proposal for Ruby and willng to undertake such a
project with a mentor who knws this stuff well..
And thnx again for ur kind feedback..

'Right currently the only "blessed" annotation is that if you have
comments justified with your first line of a method those are used for
rdoc generation

Typically to add annotations I believe you roll your own with
method_added [1 is an example].

Good luck!

re: type specifying which this link contains

Now that I think about it, I wonder if there's a way to do some type of
static ruby type hinting, a la duby, something like
module M
static_section do
typeSig a: Numeric, b: String
def go(a, b)
# this can be compiled down to C or have byte code emitted for it
or what not.
end
end
end

Then those spiffy ruby2c or JIT compilers would be helped along their
way, I guess. Just wishing for a ruby psyco still
