Re: [xmlvm-users] Few Bugs in Buffers - Patching?

[Arno P. <ar...@pu...>]

Kevin,

things are changing in XMLVM. We are in the middle of transitioning to 
the new C backend which will make the Objective-C backend obsolete. One 
benefit is that we can cross-compile Apache Harmony, so there is no 
longer the need for hand-writing J2SE classes in Objective-C (which 
means, the java.nio.Buffer bug will go away with the C backend).

There is still API missing from both the Objective-C and the C backend. 
Patches are certainly more than welcome, however, I would prefer if you 
submitted patches for the C backend, since we will deprecate the 
Objective-C backend soon.

To get you started:
- add the missing Cocoa API in xmlvm/src/xmlvm2obj/compat-lib/java
- run "ant gen-c-wrappers"
- this will generate C wrappers in src/xmlvm2c/compat-lib/iphone
- provide implementation in those wrappers between the special
   //XMLVM_BEGIN_ and //XMLVM_END_ markers

If you want to use the C backend to cross-compile iFireworks, you can do 
the following:

java -Xmx700m -jar dist/xmlvm.jar --target=iphonec \
    --in=demo/iphone/ifireworks/build/classes/ \
    --resource=demo/iphone/ifireworks/res/ \
    --app-name=iFireworks --out=out

There are also some slides in xmlvm/doc/slides that give a quick 
overview of the C backend (in the middle of the slide deck).

When you have a patch, you can upload it to our review system as 
described here: http://xmlvm.org/contribute/
