Investigate other object store implementations
----------------------------------------------
Key: JBTM-673
URL: https://jira.jboss.org/jira/browse/JBTM-673
Project: JBoss Transaction Manager
Issue Type: Task
Security Level: Public (Everyone can see)
Components: Transaction Core
Reporter: Mark Little
Assignee: Mark Little
Fix For: 4.10.0
"... spin out messaging journal into separate component so we can consume it. Also look at other disk I/O alternatives, basically trying to batch syncs so one is shared by many tx rather than one per tx. Also maybe preliminary investigation of in-memory replication of logs via jgroups."
See related links. Need to re-check performance of transaction log and maybe make it the default implementation.

update unit tests

Project: JBoss Transaction Manager
Issue Type: Task
Security Level: Public (Everyone can see)
Components: Testing
Affects Versions: 4.7.0
Reporter: Jonathan Halliday
Assignee: Jonathan Halliday
Fix For: 4.8.0
There are many unit tests that have lain dormant for some time. Convert them from DTF/junit3 to junit4, wire them to the build and make them pass.
This will be done incrementally, one module at a time, following the dependency chain e.g. common, ArjunaCore/arjuna, ArjunaCore/txoj, ... JTA/, .../JTS/...

[JBoss JIRA] Created: (JBTM-531) com.arjuna.ats.internal.jdbc.DynamicClass.shutdownDataSource(XADataSource) is never called
by Mauro Molinari (JIRA)
com.arjuna.ats.internal.jdbc.DynamicClass.shutdownDataSource(XADataSource) is never called
------------------------------------------------------------------------------------------
Key: JBTM-531
URL: https://jira.jboss.org/jira/browse/JBTM-531
Project: JBoss Transaction Manager
Issue Type: Bug
Security Level: Public (Everyone can see)
Components: JTA
Affects Versions: 4.6.0, 4.5.0
Reporter: Mauro Molinari
Priority: Critical
com.arjuna.ats.internal.jdbc.DynamicClass.shutdownDataSource(XADataSource) is never called by com.arjuna.ats.internal.jdbc.DirectRecoverableConnection.
>From what I could understand (but I'm not sure of this), after calling com.arjuna.ats.internal.jdbc.DirectRecoverableConnection.closeCloseCurrentConnection() the DirectRecoverableConnection won't be used anymore, so that method could be a good candidate to call _dynamicConnection.shutDownDataSource(_theDataSource) and to null both _dynamicConnection and _theDataSource.
This problem could be quite severe, because if the XADataSource needs to be shut down in order to release resources, this could lead to leaks.
Moreover, I was wondering if a caching of the dynamic class wouldn't be a good idea... as of now, a NEW XA data source is created every time a new connection is requested... and this could be expensive...
