[rabbitmq-discuss] c# how to get ConfirmSelect errors

Thu Sep 20 14:45:56 BST 2012

Hi Emile,

Thanks for the response.  I had come across the post 
http://www.rabbitmq.com/blog/2011/02/10/introducing-publisher-confirms/ and 
after looking at it again I noticed the example contained 
"setconfirmListener" which has now been renamed to "addConfirmListener". 
 It appears the .NET version of the rabbitMQ client does not have this 
method or ability.  It would appear this is what I am looking for but I 
have not found it in the .NET version.  Is this a lacking feature in the 
.NET version or am I not looking in the right place?

I have the ability to identify the batch of message the fault occurred in 
but I am seeking if I can identify specifically the messages in the batch. 
 I am still working through the idea if it will work if the system knows 
that a message did fail but does not know which ones.  Then working through 
if the system will work with the possibility of 1 or more publications of 
the same messages will not negatively impact the implementation.  I may 
have to implement tracking unique message ids to prevent duplicate message 
processing.

The publisher needs to remember all messages that are published, and it 
can forget about those that are confirmed. Messages that are yet to be 
forgotten about at the time of the crash will need to be redelivered as 
they might have been lost.
