[mina] Strange problem when SocketConnector connects with local address specified
Hi,
IoConnector provides methods that user can specify local address. If
local address is specified, connector binds to the specified local
address first and then connects to remote address. I added this
feature by a request of a guy called Luis Gasca because the server
authenticates his clients by its remote port number.
I added a test case that tests IoConnectors to connect to echo server
specifying local address. It passes in case of DatagramChannel, but
fails SocketChannel. It is really strange that it succeeds only about
one time out of ten iteration. I still cannot find why it fails, and
I disabled the test for now.
Any ideas?

Forgot to add, you can use setReuseAddress(true) on the
socket/serversocket object to enable it to bind on a port that is
stuck in the TIME_WAIT state.

Hi Trustin,
Since you are binding to a local address, and running the test on the
same port for DatagramChannel and SocketChannel immediately one after
the other, the port is stuck in the TIME_WAIT state due to the
previous test (Datagram), and your app gets a BindException.
This problem also exists if you try to run the current mina test cases
repeatedly.

Vinod.

Better to take this over to IRC/IM. Let me know how.
I think I found the problem.

DefaultSessionInitializer sets KEEP_ALIVE and REUSE_ADDR to true by
default, and therefore you don't need to set those properties.
The most stange thing is BindException is not thrown when
socket().bind() is called. It is thrown from finishConnect().

The problem seems to be the same - port in TIME_WAIT/ESTABLISHED state.
Even I tried using the DefaultSessionInitializer with the reuseaddress
set to true, but to no avail. What i'm trying now is using different
ports for each acceptor and connector.

That's why I skipped the test for SocketConnector. I don't have any
clues for now. Any ideas?

Hi Trustin,
Now the test failed.

Did you comment if statement like this?
//if( !(connector instanceof SocketConnector) )
//{
// FIXME This test fails in case of SocketConnector.
// I don't know why yet.
System.out.println("* With localAddress and without initializer");
testConnector( connector, localAddress, null );
marker = new MarkingInitializer();
System.out.println("* With localAddress and initializer");
testConnector( connector, localAddress, marker );
Assert.assertTrue( marker.executed );
//}

Was looking in the right place, but in the wrong version :)
Actually, the test is working just fine for me. Even ran it multiple times.

This is weird. If you send me the code, I could check it out here.

The strange thing is that BindException is not thrown when I call
bind(), but thrown when finishConnect(). I tried to set ReuseAddress
and SoLinger, but none helped me out. I also chose different port
each time I test, and failed too.
