RE: [jira] Commented: (OPENJPA-35) In-memory Delete operation fails with active DataCache
Posted by Pinaki Poddar <pp...@bea.com>.
Patrick,
I added the trace output of the test for "delete via query does not
remove the copy from the L2 cache".
The deleted instance was locked/modified after the transaction that
deleted it was committed.
Does that signal the L2 cache to heal itself?

I'm wondering whether or not the cache is properly healing itself, which
gives us a feel for how severe the problem is.

I am interested in the behavior when using delete-by-query, as I'm
pretty sure that I know what will happen in that situation.
My expectation is that the cache will clean itself up after the initial
locked read or write, which isn't nearly as bad as the cache never
cleaning itself up, but clearly worse than the cache cleaning itself up
in the first place.

RE: [jira] Commented: (OPENJPA-35) In-memory Delete operation fails with active DataCache
Posted by Pinaki Poddar <pp...@bea.com>.
do you mean to lock or modify the object *after* delete?
something like:
em.begin();
em.remove(pc);
em.commit();
pc.setSomething();
em.lock(pc, READ);
....

I was referring to subsequent transactions after the delete. The delete
happens in its own persistence context, meaning that anything that has
happened in the transaction to date is basically ignored.

RE: [jira] Commented: (OPENJPA-35) In-memory Delete operation fails with active DataCache
Posted by Pinaki Poddar <pp...@bea.com>.
The issue is now better be stated as "Delete by Query does not remove
the copy from L2 cache".
a) Tried to lock the instance, before delete causes commit to fail
with OptimisticVerification
b) Modifying the object before delete causes no change in behaviour
in the scope of the given test.

Well, I think that it's worth *fixing*, and shouldn't really be all that hard, either. But, assuming that we can't prioritize it appropriately to fix it, we should document it prior to the next release, yes.

Pinaki Poddar commented on OPENJPA-35:
--------------------------------------
Right -- a newly looked up copy (the copy comes out of L2 cache and not from the database where it really do not exist anymore) -- is essentially not usable i.e. any commit set containing that object fails. The L2 cache heals as soon as the commit fails.
So let me summarize
a) delete via query leaves a copy in the L2 cache
b) the cached copy can be located via em.find()
c) however, any modify operation on this ghost copy will fail
d) this failure will signal to clear the copy from the L2 cache.
Do you think, it is worth mentioning in the doc?

Pinaki Poddar updated OPENJPA-35:
---------------------------------
Attachment: openjpa-35.test.zip
Attached test case shows that after deleting via query, L2 cache still maintains a copy and em.find() finds the instance.

I think that this is fine behavior. You generally shouldn't need to get the StoreCache's delegate. The current behavior is nice because user code doesn't need to check whether or not a cache is active; instead, user code can just perform cache operations. Sure, they're no-ops when the cache isn't on, but that's fine.

----------------------------------------
... to finish that thought, I'd then expect that the instance would get cleared from the cache due to the optimistic lock failure, and a second transaction involving the instance (a newly-looked-up copy) would succeed.

[jira] Commented: (OPENJPA-35) In-memory Delete operation fails
with active DataCache

Patrick Linskey commented on OPENJPA-35:
----------------------------------------
I haven't looked at your test, but I'm guessing that since it has a DetachedStateManager, it's the same instance that you had been using earlier.
I would expect that if you deleted some instances with a bulk delete, then looked up an instance that had been deleted via a data cache hit, then tried to do anything involving a lock with that instance, you'd get a failure at commit time (assuming optimistic transactions and a @Version column).

[jira] Commented: (OPENJPA-35) In-memory Delete operation fails

Posted by "Pinaki Poddar (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/OPENJPA-35?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12476719 ]
Pinaki Poddar commented on OPENJPA-35:
--------------------------------------
I am not seeing this particular error anymore -- but I am seeing something else that does not appear right.
a) When datacache is active, even after an instance is deleted via query, the entitymanager is committed and cleared, EntityManager find() finds the instance -- not from its L1 cache but from its L2 cache.
If this is a known limitation -- it should be documented (could not find it in OpenJPA User's guide)
b) When openjpa.datacache=false, the application can still obtain a non-null reference to StoreCache, however its delegate is null.
What should OpenJPAEntityManagerFactory.getStoreCache() return when openjpa.datacache=false ?
c) delete directly i.e. em.remove() does the 'right' thing i.e. subsequent em.find() returns null.
d) Setting "openjpa.BrokerImpl" to "EvictFromDataCache=true" did not change the behavior (nor was expected)
The observations are based on the attached TestCase

[jira] Updated: (OPENJPA-35) In-memory Delete operation fails with
active DataCache
Posted by "Pinaki Poddar (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/OPENJPA-35?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Pinaki Poddar updated OPENJPA-35:
---------------------------------
Attachment: openjpa-35.trace.txt
Added a trace output of the test case that is failing.
shows that the deleted instance (PObject-4501) is in L2 Cache.
Please note the instance was locked and modified *after* delete by query (as we still has its reference).
Does that give the cache a chance to heal?
Please note that PObject-4501 has a DetachedStateManager when we lock/modify it after delete.
