[xmlvm-users] Success & code contribution question

[Dr. A. K. S. <al...@se...>]

Hi all,

I've finally managed to port the core audio processing library from
my android app to iphone and tested it... it works perfectly with <1E-6
difference! (still with --use-jvm)

On the way I had to implement some compatibility objectiveC code
which I'm willing to contribute. This is basically...
* a pretty complete java_util_Vector (based on NSMutableArray)
* a pretty complete java_io_FileInputStream (using a memory buffer
  for simplicity, might have some leaks, did not put the
  same functions in InputStream as abstract implementations...
  sorry, was in a hurry)
* adding many functions to java_lang_Math
* java_lang_Double with conversion functions

* minor stuff:
+ logging the processed code file in ObjectiveCOutputProcess.java
  This makes finding java source file with still missing opcodes
  so much easier to find!
+ adding the wav file type to XCodeFile
	This automatically adds them to the resources. A workaround to
  support raw resources would be to rename all Android resources
  in res/raw to .raw extension, run android build to get R.java,
  add the .raw file type to XCodeFile and also add an access function
  to android/content/res/Resources.java like this:
    public FileInputStream openRawResource(int resourceId) throws Exception {
      String fileName = getFileNamePath(findResourceNameById(resourceId));
      String filePath = NSBundle.mainBundle().pathForResource(fileName,"raw");
      return new FileInputStream(filePath);
    }
  Works for .wav, at least!

What is the best way for me to contribute code? For now there is no
major discrepancy with the svn repository, but it is only a matter
of time... ;-)

Best,
  Alex

Great to hear that you would like to contribute to XMLVM! Please have a
look at http://xmlvm.org/contribute/. There we describe the process of
contributing to XMLVM. Basically you have to sign our Contributor
License Agreement (CLA) and submit a patch file to our code review
portal at http://xmlvm-reviews.appspot.com/ . After reviewing the
changes we will merge them to our SVN repository.

If you have any further questions, let us know.

Hi Wolfgang,

I've signed the CLA and uploaded the first batch of patches. Most of
these should be ok; for java_io_FileInputStream Gergely's version
will surely be better. ;-)

The changes should work well with Rev. 862.

Best,
  Alex

Hi,

We are also in the process of preparing a similar patchset, with some
overlaps:

- Parts of Collections framework (List, Map, Vector, ArrayList, LinkedList,
Hashtable): All based on NSMutableArrays and NSMutableDictionaries.
- Parts of the IO framework (FileInputStream, FileOutputStream,
ByteArray*Stream, InputStreamReader)
- Synchronization (Threads, proper implementation of synchronized blocks and
methods, wait, notify)
- and various other bits and pieces (Math, different number classes ...
etc.)

We are struggling with getting our private xmlvm branch up to the latest
trunk so we can send back the patches, and also with trying to meet a
deadline with our project.

Best Regards,
Gergely

there seems to be a little overlap, but both of you have done some 
interesting extensions. We are definitely interested to merge these back 
with the trunk. We'll work with you to make that happen.
