Robbie Gemmell closed QPID-952.
-------------------------------
Resolution: Won't Fix
Closing thess issues out as they relate to the old 0-8 and 0-10 .Net clients
which were removed from the repository months ago, and not the current .Net
bindings for the C++ messaging API.
> .NET NetworkStream does not immediately detect connection failure.

> Key: QPID-952
> URL: https://issues.apache.org/jira/browse/QPID-952
> Project: Qpid
> Issue Type: Bug
> Components: Dot Net Client
> Affects Versions: M1, M2, M2.1
> Reporter: Martin Ritchie
>
> Summary:
> The NetworkStream used by the Blocking IO does not immediately report the
> underlying socket connection failure. It can take up to 20 seconds before
> this is reported. According to the API:
> http://msdn2.microsoft.com/en-us/library/system.net.sockets.networkstream.read(VS.71).aspx
>
> The Read call only returns zero when the connection has been closed. So we
> can close the underlying socket which will stop all sends and force an
> exception on the next read attempt. This in turn will cause failover to be
> triggered.
> Defect Identification:
> When running with debug on you can see lots of 'Read() 0' logged out when the
> broker is killed. This is due to the NetworkStream returning 0 instantly as
> described in the API docs, as a result of the socket being gracefully
> shutdown. Unfortunately it is still possible to send data without an
> exception so sends can be lost.
> Proposed Changes:
> If we get 0 bytes being read from the NetworkStream we can block sends and
> shutdown the socket which will cause failover to occur in the next read loop.
