[jira] [Created] (DIRMINA-917) IoHandlerAdapter.sessionClosed is
not call when the clien close a connection
xieyufeng created DIRMINA-917:
---------------------------------
Summary: IoHandlerAdapter.sessionClosed is not call when the clien close a connection
Key: DIRMINA-917
URL: https://issues.apache.org/jira/browse/DIRMINA-917
Project: MINA
Issue Type: Bug
Components: Handler
Affects Versions: 2.0.3
Environment: OS:Debian 2.6.32-41
MINA Version:2.0.3
Reporter: xieyufeng
Priority: Critical
My Client Code:
public static void main(String[] args) throws Exception {
Socket[] sockets = new Socket[100];
try {
for (int i = 0; i < 100; i++) {
// sockets[i]=new Socket(args[0], Integer.parseInt(args[1]));
sockets[i] = new Socket("*.*.*.*", 8282);
try {
Thread.sleep(1);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
} catch (Exception e) {
e.printStackTrace();
}
while (true) {
try {
Thread.sleep(100000);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
where the 100 connection finished,"sessionCreated(IoSession session)" called 100 times(It's OK),Then I kill the client process.I found" sessionClosed(IoSession session)" only called 33 times,"exceptionCaught(IoSession session, Throwable cause) " called 65 times.So I suggest “sessionClosed” is not called every time .

[jira] [Resolved] (DIRMINA-917) IoHandlerAdapter.sessionClosed is
not call when the clien close a connection

Emmanuel Lecharny resolved DIRMINA-917.
---------------------------------------
Resolution: Not A Problem
This is plain normal. If you brutally kill your process, or unplug your network cable, the server won't be informed that the client has been disconnected.
If you want the server to be informed that the clients are disconnected, then the clients have to safely close the sockets they are using.
Note this is not specific to MINA : it's exactly the same problem in C or any other language.
