Subject [jira] Updated: (HARMONY-6493) [classlib][nio]DatagramChannel should be "bounded" after calling the sendto
Date Tue, 06 Apr 2010 02:28:27 GMT

Ray Chen updated HARMONY-6493:

    Attachment: Harmony6493.diff

The patch contains the fix and a regression test.

The fix is quite simple, just makred the bound status to "true" after calling the sendto function.
The reason for doing that is because that "With a UDP socket, the first time the process calls
sendto, if the socket has not yet had a local port bound to it, that is when an ephemeral
port is chosen by the kernel for the socket. "
And the testcase will show the difference.

However, there are another issue need to be disscussed:  
At first, I used
"InetSocketAddress addr = new InetSocketAddress("localhost",0);"
to let the OS to pick up a free port  number, but the server can not receive the client's
message in that way.
So I change the port number to a fixed number, everything works well.
Anyone have any idea about this? Any sugguestions are welcome!
