int[].class and DeflaterInputStream fails #114

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago
What steps will reproduce the problem?

int[] testArray = new int[100];
Arrays.fill(testArray, 6);
Output output = new Output(new 
DeflaterOutputStream(Gdx.files.external("kryofile.bin").write(false)));             
kryo.writeObject(output, testArray);
output.close();

//.....

FileHandle fh = Gdx.files.external("kryofile.bin");

if(fh.exists())
{
   Input input = new Input(new DeflaterInputStream(fh.read()));

   int[] testArray = kryo.readObject(input, int[].class);
   input.close();   
}   

What is the expected output? What do you see instead?
Expected: An evil array full of sixes ;)
but get this instead.

What version of the Kryo are you using?

kryo-2.21-all.jar

Please provide any additional information below.

Also, if you remove the DeflaterIOSteam it works fine.

Maybe it's time for a new release, it seems some recent commits might have 
fixed this problem :)
I'll try the trunk later

Just built a snapshot from trunk with maven, it seems the problem is still 
there. Same crash stack.

Also tried to use this:

kryo.register(int[].class, new 
DeflateSerializer(kryo.getDefaultSerializer(int[].class)));

Removing the DeflaterIOStream usage from the input/output.

There's no crash stack, but kryo.readObject(input, int[].class); returns a null 
object

So i'm clueless now, how can i save primitive arrays?

Okey finally replaced the DeflaterStream with GZIPStream and now it works. Good 
enough, but the original bug remains and the docs (Compression and encryption) 
on the project home are leading to it.

Don't use DeflaterInputStream. Try this:
Input input = new Input(new InflaterInputStream(fh.read()));

Ow i see now, very misleading stream terminology. :)
Thanks
