Emmanuel Lecharny commented on DIRMINA-777:
-------------------------------------------
It will be closed if we consider that it's a real issue, or if we consider this
is not. Still to be evaluated, as I don't have an Android device to test the
issue, and as I don't have the full code of the client and server to reproduce
it.
> IoSessionConfig.setUseReadOperation(true) doesn't seem to work

> Key: DIRMINA-777
> URL: https://issues.apache.org/jira/browse/DIRMINA-777
> Project: MINA
> Issue Type: Bug
> Components: Core
> Affects Versions: 2.0.0-RC1
> Environment: Mac OS X 10.6.2, Java 1.6, Android SDK
> Reporter: Matt Huggins
> Priority: Blocker
> Fix For: 2.0.3

> I'm attempting to perform a synchronous write/read in a demux-based client
> application with MINA 2.0 RC1, but it seems to get stuck. Here is my code:
> {code}
> public boolean login(final String username, final String password) {
> // block inbound messages
> session.getConfig().setUseReadOperation(true);
> // send the login request
> final LoginRequest loginRequest = new LoginRequest(username, password);
> final WriteFuture writeFuture = session.write(loginRequest);
> writeFuture.awaitUninterruptibly();
> if (writeFuture.getException() != null) {
> session.getConfig().setUseReadOperation(false);
> return false;
> }
> // retrieve the login response
> final ReadFuture readFuture = session.read();
> readFuture.awaitUninterruptibly();
> if (readFuture.getException() != null) {
> session.getConfig().setUseReadOperation(false);
> return false;
> }
> // stop blocking inbound messages
> session.getConfig().setUseReadOperation(false);
> // determine if the login info provided was valid
> final LoginResponse loginResponse =
> (LoginResponse)readFuture.getMessage();
> return loginResponse.getSuccess();
> }
> {code}
> I can see on the server side that the LoginRequest object is retrieved, and a
> LoginResponse message is sent. On the client side, the
> DemuxingProtocolCodecFactory receives the response, but after throwing in
> some logging, I can see that the client gets stuck on the call to
> `readFuture.awaitUninterruptibly() `.
> I can't for the life of me figure out why it is stuck here based upon my own
> code. I properly set the read operation to true on the session config,
> meaning that messages should be blocked. However, it seems as if the message
> no longer exists by time I try to read response messages synchronously.
