[jira] Created: (QPID-3059) Example TopicListener.cs does not await

Example TopicListener.cs does not await the arrival of messages
---------------------------------------------------------------
Key: QPID-3059
URL: https://issues.apache.org/jira/browse/QPID-3059
Project: Qpid
Issue Type: Bug
Components: Dot Net Client
Environment: Linux, Mono JIT compiler version 2.6.7 (tarball Mon Jul 19 18:28:58 UTC 2010)
Reporter: Keith Wall
Priority: Minor
I'm trying to run the TopicListener/TopicPublisher provided in the source tree of the dotnet 0.8 client (The Java Broker Compatible client) . I'm running on a Linux host under Mono.
I find when I execute TopicListener.exe it immediately writes "Waiting for messages..." to the console and then exits. The problem seem to me that the main thread is being allowed to terminate so the program is exiting before it has a chance to hear the messages of TopicPublisher.
mono ./bin/mono-2.0/debug/TopicListener.exe
Waiting for messages..."

Keith Wall updated QPID-3059:
-----------------------------
Environment:
Linux, Mono JIT compiler version 2.6.7 (tarball Mon Jul 19 18:28:58 UTC 2010) and
Windows 7
was:Linux, Mono JIT compiler version 2.6.7 (tarball Mon Jul 19 18:28:58 UTC 2010)
I have reproduced the same issue natively on Windows 7 too. Behaviour is as Linux/Mono - TopicListener program exits immediately without awaiting the arrival of the message.
Also verified that the patch resolves the defect on Windows platform too.

------------------------------------------------------------
Changed TopicListener example code. It now uses a monitor to either await the arrival of the the shutdown message (from TopicPublisher), or a timeout occurs.
I puzzled how the example has ever worked. The Dispatcher thread created in ./Qpid.Client/Client/AmqChannel.cs has always had IsBackground set to true, and http://msdn.microsoft.com/en-us/library/h339syd0%28v=vs.71%29.aspx says "a background thread will not keep the managed execution environment alive" so without a foreground thread, the VM will always terminate.
