Re: [Gems-users] Support for XactRequestGenerator in Ruby tester

[Jayaram Bobba <bobba@xxxxxxxxxxx>]

You are right. XactRequestGenerator and XactAbortRequestGenerator are no 
longer supported.
In Gems 2.0, we have moved most of the TM functionality out of the 
protocols. Moreover, some of the TM functionality (like unrolling the log)
is done within software. Implementing a ruby-only tester for TM would 
require implementing the software component
of TM within the tester. There is other sw/hw interface code (for eg. 
logging in TransactionVersionManager.C) that needs to be made aware of this
dual possibility (either software or tester). In short, I think it is 
not straightforward and we have not yet taken the time to do it. However,
if you are working on a new TM protocol, it might be a valuable addition.
