Description Brian Stansberry 2014-04-29 00:50:55 UTC
Description of problem:

The subsystem=transaction/log-store=log-store has a 'probe' operation that inadvertently clears the 'type' attribute from the resource.


How reproducible:

Always

Steps to Reproduce:
1. Invoke /subsystem=transaction/log-store=log-store:probe
2. Invoke /subsystem=transaction/log-store=log-store:read-resource

Actual results:

The 'type' attribute is undefined

Expected results:

The 'type' attribute should be defined

Additional info:

LogStoreProbeHandler replaces the 'delegate' held by LogStoreResource. Doing this removes any data from the existing delegate's 'model' field, i.e. the "type" attribute.

Comment 2 Brian Stansberry 2014-05-09 14:47:25 UTC
The steps to reproduce were incomplete. You only see the problem if the type attribute does not have value 'default'.

So, before the step I listed, either add the <use-hornetq-store/> element to the transaction subsystem config, or do it via the CLI with

batch
/subsystem=transactions:write-attribute(name=use-hornetq-store,value=true)
/subsystem=transactions:write-attribute(name=use-jdbc-store,value=false)
run-batch
reload

Thank you for the additional info about verification the issue.

I've checked the behavior of EAP 6.3.0.ER3 and I have one cosmetic note about the failure behavior.
After the probe() operation is run the type of the log-store is not put to 'undefined' but is changed back to default 'default' value.

Comment 4 Brian Stansberry 2014-05-09 15:26:38 UTC
Agreed. I've changed the text. Thanks!

Comment 5 Ondrej Chaloupka 2014-05-21 13:34:51 UTC
Verified on EAP 6.3.0.ER4
