Martin Illecker updated HAMA-805:
---------------------------------
Attachment: HAMA-805.patch
Please verify my patch.
Problem: The default Hama Pipes UplinkReader was used, instead of
StreamingUplinkReaderThread!
Solution: The StreamingUplinkReaderThread overrides the default UplinkReader in
StreamingProtocol.
I also made a minor update [1] to the Streaming API, but that's not connected
to this issue.
The updated version can be found here [2]:
{code}
git clone git://github.com/millecker/HamaStreaming.git
{code}
Maybe we should include Hama Streaming into the trunk? (Subfolder of pipes
module)
