Re: Eclipse Plugin for OpenJPA

Can you check the source into the OpenJPA sandbox, so others can help 
setup the builds/legal files before we import it into a real branch?

Hi,
  I am still in the process of figuring out how to build this stuff without
the help of Eclipse PDE.
Will get the legal issues surely sorted out once we get the mechanics right.

Pinaki, can we at least get a copy of the current plugin source checked 
into openjpa/sandboxes, until we decide on how to build/release it?

If you don't have time to check-in the files, just send me a tar/zip and 
I'll work on it.

I am also trying to use this plugin as an exemplar for openjpa-contrib [1].
Hence, I will add a openjpa-contrib module (without any dependency to our normal builds). 
Then create a openjpa-contrib/eclipse -- and donate the code underneath in standard src/main/java directory structure. Based on your experience with Genonimo Eclipse plug-ins, feel free to modify that structure, if needed.
After researching on how maven can build a plugin that can also be used in Eclipse PDE environment -- which turned out to be non-trivially complex -- I am considering whether Ant will be the right tool for this purpose.

Pinaki, have you had the chance to upload the current source code 
anywhere?  Can you place it under -

and I'll login and grab it from my account on p.a.o?

Re: Is setQueryCache() broken, and how to fix?

Posted by Michael Dick <mi...@gmail.com>.

Hi Joe,

I'd say this is a bug.

OpenJPAQuery q = OpenJPAPersistence.cast(em.createQuery("Select p from
Person p");
q.setQueryCacheEnabled(false);  // should behave identically to disabling
the query cache in the config.

I'm not terribly familiar with that part of the code, but if you're
interested in pursuing the problem I'll try to help.

Is setQueryCache() broken, and how to fix?

Posted by Joseph Weinstein <jo...@oracle.com>.

Hi all, I am starting my climb to being able to fix OpenJPA bugs,
and would like anyone's opinion on a case I want to fix or at least
explain.
  My current problem involves a case where the application code wants
no query cache, and causes setQueryCache(false) to be called, reaching
class

org.apache.openjpa.jdbc.kernel.JDBCFetchConfigurationImpl

Note that QueryCache is set to true in the properties file. Then the
code executes a query, and during the query, and during it's processing
I nevertheless see caching:

     [java]     at org.apache.openjpa.datacache.ConcurrentQueryCache.putInternal(ConcurrentQueryCache.java:124)
     [java]     at org.apache.openjpa.datacache.AbstractQueryCache.put(AbstractQueryCache.java:115)
     [java]     at org.apache.openjpa.datacache.DelegatingQueryCache.put(DelegatingQueryCache.java:124)
     [java]     at org.apache.openjpa.datacache.QueryCacheStoreQuery$CachingResultObjectProvider.checkFinished(QueryCacheStoreQuery.java:561)
     [java]     at org.apache.openjpa.datacache.QueryCacheStoreQuery$CachingResultObjectProvider.next(QueryCacheStoreQuery.java:593)
     [java]     at org.apache.openjpa.lib.rop.EagerResultList.<init>(EagerResultList.java:35)
     [java]     at org.apache.openjpa.kernel.QueryImpl.toResult(QueryImpl.java:1219)
     [java]     at org.apache.openjpa.kernel.QueryImpl.execute(QueryImpl.java:987)
     [java]     at org.apache.openjpa.kernel.QueryImpl.execute(QueryImpl.java:796)
     [java]     at org.apache.openjpa.kernel.QueryImpl.execute(QueryImpl.java:766)
...

If I totally turn off caching in the config, we use a 
org.apache.openjpa.jdbc.kernel.InstanceResultObjectProvider
being used, not a QueryCacheStoreQuery...

So how should the no-cache state in JDBCFetchConfigurationImpl
have reached/affected the query processing?

thanks in advance for your expertise,
