[infinispan-dev] ISPN-296 closed but not sure why

Wed Dec 16 13:15:48 EST 2009

Just did some more testing here and it appears to do with the
transaction manager.  We're using jbossts-jta-4.9.0.GA.  If I use the
default DummyTransactionManager everything "appears" to work.

When I debugged my JUnit test (I'm not sure how to debug your tests)
using the DummyTransactionManager I could see the problem still occurs
but on line 263 of DummyTransaction.java the exception thrown is
consumed.  A log line is generated but that's it.  I'm not sure how to
view a log in your tests but I couldn't see the message anywhere in the
reports.

You said you tested with the attached jbossts-properties.xml so I assume
you were using the same or similar transaction manager so I'm not sure
why you can't reproduce this.  I can now reproduce "success" by using
the DumyTransactionManager but I don't think the DummyTransactionManager
is handling this properly or making it apparent.

The problem in the code appears to be when removing the value from the
index (QueryInterceptor.java 166) a bit of work is passed in and the
value is null because it doesn't exist in the cache.  In
BatchedQueueingProcessor (line 148) in the hibernate-search code the
following code is run.

           Class<T> entityClass = work.getEntityClass() != null ?

                     work.getEntityClass() :

                     Hibernate.getClass( work.getEntity() );

The entityClass is the class of the value.  The value is null so
therefore it runs Hibernate.getClass(work.getEntity()); and then throws
a NullPointerException.  This is the exception that the
DummyTransaction.java consumes.

Anyhow, this is what I'm seeing.

Hmm, I just did this and ... it worked!

Ok, what I did was *slightly* different - I put your XML files on my
classpath and created a CacheManager using:

      m_cacheManager = new
DefaultCacheManager("datagrid-infinispan.xml");

      m_cache = m_cacheManager.getCache();

      m_transactionManager =
m_cache.getAdvancedCache().getTransactionManager();

      return m_cacheManager;

This is the same datagrid-infinispan.xml (and jbossts-properties.xml)
that you attached at the start of this thread.

Cheers

When I run the test as configured the test succeeds.  When I use the

   @Override

   protected CacheManager createCacheManager() throws Exception {

      //Configuration c = getDefaultStandaloneConfig(true);

      //c.setIndexingEnabled(true);

      //c.setIndexLocalOnly(true);

      //m_cacheManager = TestCacheManagerFactory.createCacheManager(c,
true);

      InputStream is = new FileInputStream("infinispan.xml");

      m_cacheManager = new DefaultCacheManager(is, true);

      m_cache = m_cacheManager.getCache();

      m_transactionManager =
m_cache.getAdvancedCache().getTransactionManager();

      return m_cacheManager;

   }

I don't think there is a lot different from the standard config other
than the following.

 - We use FIFODataContainer with no eviction

 - We've got JMX turned on.

 - Lock striping is turned off

 - We're running in local mode

You can run the test from the src tree if you check it out, set it up
accordingly as per instructions here [1] and run the test in your IDE.

I've updated to CR3 and it appears this issue is still there.  Is there
a way to see the output of this test?  There should be exceptions being
thrown.

FYI, I've also added this as a unit test (modified to work with our test
fwk) and it works fine in trunk.

The issue has been closed but I can reproduce it.  I'm not sure if it
was closed because it could not be reproduced or because it not felt as
a bug.

https://jira.jboss.org/jira/browse/ISPN-296

I've attached a simple test to reproduce the problem.  Just a reminder.
When running the test make sure to add -Dinfinispan.query.enabled=true
-Dinfinispan.query.indexLocalOnly=true to enable query support.
