[xmlblaster] What happens to pubed msgs when history que is full?

[Marshall Shapiro <mshapiro at draper.com>]

We are developing an application using xmlBlaster and a important issue 
came up.

I am confused about what happens to messages that are published to topics 
when the topic history queue is full.

In the engine.message requirement doc I found the statement "Further 
published messages with the same oid overwrite the previous message (the 
history depth is one)".

But someplace else in the documentation I found a that the default setting 
of the PublishQos attribute OnOverflow is "deadMessage", and that the 
attribute setting "discardOldest" may not yet implemented.

I don't know how to reconcile these. Please clarify (for both queue length 
equal 1 and queue length greater than 1).

This becomes an important issue for me in that my app requires that the 
latest publication to a topic always be in the queue, overwriting the older 
ones.

Thanks.
