[jira] Created: (HARMONY-754) [classlib][nio]
java.nio.channels.DatagramChannel.read(ByteBuffer[]) and
read(ByteBuffer[],int,int) fail to return even some data are available.
[classlib][nio] java.nio.channels.DatagramChannel.read(ByteBuffer[]) and read(ByteBuffer[],int,int) fail to return even some data are available.
------------------------------------------------------------------------------------------------------------------------------------------------
Key: HARMONY-754
URL: http://issues.apache.org/jira/browse/HARMONY-754
Project: Harmony
Type: Bug
Components: Classlib
Reporter: Andrew Zhang
java.nio.channels.DatagramChannel.read(ByteBuffer[]) and read(ByteBuffer[],int,int) fail to return even some data are available.
Following test reproduces the problem:
public void test_read_$LByteBuffer() throws Exception {
int capcity = 64;
DatagramChannel channel1 = DatagramChannel.open();
DatagramChannel channel2 = DatagramChannel.open();
// make connection between channel1 and channel2
channel1.socket().bind(
new InetSocketAddress(InetAddress.getLocalHost(), 0));
channel2.socket().bind(
new InetSocketAddress(InetAddress.getLocalHost(), 0));
channel1.connect(channel2.socket().getLocalSocketAddress());
channel2.connect(channel1.socket().getLocalSocketAddress());
// channel2 writes some data to channel1
channel2.write(ByteBuffer.allocate(capcity));
ByteBuffer[] readBuf = new ByteBuffer[2];
readBuf[0] = ByteBuffer.allocateDirect(capcity);
readBuf[1] = ByteBuffer.allocateDirect(capcity);
channel1.configureBlocking(true);
// channel1 reads some data from channel2
// Harmony hangs at this line.
long ret = channel1.read(readBuf);
assertEquals(capcity, ret);
}
RI passes the test while Harmony fails.
I'll upload a patch soon.
Thanks!
Best regards,
Andrew
