---------------------------------------
Thanks Knut for fixing DERBY-3883. It looks like a good fix albeit not related to this issue. I still see the failure with your patch and this is what I think is going on.
What I see with IBM 1.6 is that by the time we get to rollback() the Lob references have already been removed from the WeakHashMap EmbedConnection.lobReferences but have not yet been garbage collected. I think it is ok for WeakHashMap to do this. The javadoc says.
The behavior of the WeakHashMap class depends in part upon the actions of the garbage collector, so several familiar (though not required) Map invariants do not hold for this class. Because the garbage collector may discard keys at any time, a WeakHashMap may behave as though an unknown thread is silently removing entries.
Changing the WeakHashMap to a HashMap corrects this problem, ensuring that when we get to rollback() the entries will still be there, but I am sure there must be a good reason for using a WeakHashMap in this case. Does anyone know why we use WeakHashMap instead of HashMap, when it seems ultimately we will get to the end of the transaction and clear these entries?

---------------------------------------
I added the synchronization because I think there is the potential for free to be called by both the finalizer and removeLobFile at the same time. Without the synchronization it might cause an NPE.

-------------------------------------------
I was under the impression that EmbedConnection.commit() and EmbedConnection.rollback() would iterate over the list of lobs and call Embed[BC]lob.free(), which again would call LOBStreamControl.free() and close the file. Why isn't that happening?

---------------------------------------
Actually playing with the gc() on clearLobMapping solution, I see that it is not a good idea as it seems to have a performance impact and even hung one test (not sure what that's about), maybe the gc() on shutdown makes more sense.

Knut Anders Hatlen commented on DERBY-3655:
-------------------------------------------
My thought was to have one instance per database since it sounds too heavy to create one per transaction. It might be that it's too complex to be worth it, though.
Another idea is to just add a list/set of file objects (either LOBFile or RandomAccessFile) in EmbedConnection. Each time LOBStreamControl creates a temporary file, it is added to the list/set, and each time LOBStreamControl closes a temporary file, it is removed. Since there are no references from LOBFile/RandomAccessFile to Embed[BC]lob, this list won't prevent the lob objects in the WeakHashMap from being gc'ed. And if an object has been gc'ed and removed from the WeakHashMap, and finalization is still pending, a reference to the file is accessible from EmbedConnection on the transaction boundary so that it can be closed.

Knut Anders Hatlen commented on DERBY-3655:
-------------------------------------------
Thanks for doing the research, Kathey. So the problem seen from the users' perspective is that they can't necessarily delete the database until finalization has been performed after the database shutdown if they have accessed lobs.
I don't know what's the best way to fix this, but I would strongly oppose forcing gc and finalization as part of the normal commit/rollback logic as it is not guaranteed to have any effect and may have a significant performance impact. Doing it as part of the database shutdown wouldn't be that problematic, but I feel that we should try to avoid explicit gc if we could.
One thought is that LOBStreamControl could use a cache (instance of CacheManager) of open file descriptors used for temporary lobs, kind of like the container cache. If the file descriptor is in the cache when LOBStreamControl needs it, it can just fetch it. Otherwise, the cache would have to reopen the temporary file and return the new file descriptor. When a [BC]lob object is finalized, it invalidates the cache entry and closes the file descriptor. If the [BC]lob object is gc'ed but not finalized when the database is shut down (as in the problem case in this issue), we'll still have a reference to the file descriptor in the file descriptor cache, and we can close it as part of the database shutdown.
Just a half-baked idea for now, but I think it should work, with the additional benefit of reducing the peak in the number of open file descriptors we can get when we open many lobs in the same transaction without explicitly freeing them, and also reducing the reliance on gc to free up resources for us.

[jira] Commented: (DERBY-3655) errror in nightly regression test:
LobStreamsTest:encryptedjunit.framework.AssertionFailedError:
f:\jartest\JarResults.2008-04-29\ibm16_suites.All\system\singleUse\oneuse1e\tmp\lob6165.tmp
Posted by "Knut Anders Hatlen (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/DERBY-3655?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12636411#action_12636411 ]
Knut Anders Hatlen commented on DERBY-3655:
-------------------------------------------
I lean slightly towards clearing it, I think. If an EmbedConnection instantiates a set in one transaction, it is probably more likely to use it in the subsequent transactions too, so clearing and reusing the object makes sense. We don't save that much memory by nulling it out in the situations where it's not reused, so it shouldn't hurt. But I think the performance penalty of overflowing to a temporary file is so high that the cost of allocating a new HashSet is negligible, and therefore either approach would be fine.

----------------------------------
I have not had a chance to try and reproduce or debug, but from the stack it seems similar to previous problems in teardown where
the running test or the previous test has not properly cleaned up leaving some sort of open on the file or the file in a directory and then the teardown on windows can't clean up.

Myrna van Lunteren resolved DERBY-3655.
---------------------------------------
Resolution: Cannot Reproduce
I've looked at the results for the automated tests at IBM and I haven't seen this failure again...
If it happens again, we can try to spend more time, but I believe on the whole the cleanup troubles should be fixed now...

Kathey Marsden updated DERBY-3655:
----------------------------------
Attachment: derby-3655_diff.txt
Attached is a patch implementing Knut's suggestion to keep a set of LOBFile's in EmbedConnection so that they can be closed at transaction boundaries. It corrects the problem with IBM 1.6 sr2 and passed suites.All and derbyall.
Please Review

Kathey Marsden commented on DERBY-3655:
---------------------------------------
Here is the comment from the checkin that introduced the WeakHashMap
DERBY-3354: Select from large lob table with embedded gives OutOfMemoryError
Contributed by Anurag.
This patch introduces a new WeakHashMap in EmbedConnection. EmbedBlob and EmbedClob objects references are stored in this
map (objects as key and null as value). Adding entry to locater map is
differed till the first call of getLocater.
This ensures that there is entry of LOB objects in locater map if they are invoked in embedded mode.
As the keys of WeakHashMap doesn't prevents the objects from being
garbage collected, once the lob objects are unreferenced lob objects will
be garbage collected releasing the memory.
During commit/rollback or Connection.close, free is invoked on all the lob
objects from WeakHashMap and the map is cleared.
So, I guess the reason for the WeakHashMap is so that blobs that are no longer referenced can be garbage collected before the transaction ends. Perhaps the correct solution is to force a gc and finalization after clearLobMapping does its work.

Knut Anders Hatlen commented on DERBY-3655:
-------------------------------------------
Thanks, Kathey! I think the patch looks very good. Some small comments:
- Should we also call removeLOBFile() from truncate() and replaceBytes() in LOBStreamControl? Those methods also close the file. (Perhaps a helper method to do close+remove would be appropriate?)
- addLobFile() and removeLobFile() could be package private
- Could LOBStreamControl.conn be made final?
- Typo in javadoc for addLobFile(): fileto -> file to
- "@param dbName" should be removed from LOBStreamControl's constructors
- Not necessary as part of this issue, but in a follow-up patch we may consider removing the dbName field from LOBStreamControl. It's only used once in init(), so just calling conn.getDBName() would be simpler now.

Kathey Marsden commented on DERBY-3655:
---------------------------------------
This happens reliably with IBM 1.6 service release 2. I noticed if I force a gc() before removing the directory the issue does not occur as the temporary Lobs are garbage collected and their finalize method is called to close the temporary lob file. I don't know if it is appropriate to force a gc() when we shutdown the database so the temporary lob objects get garbage collected or if we should make an effort to keep a reference to these files so they can be closed on shutdown.

Thanks Knut, I will change it to go back to lazy creation. One question. Do you think it is better on clearLobMapping, if lobFiles exists, to set lobFiles to null or to clear it?

Knut Anders Hatlen commented on DERBY-3655:
-------------------------------------------
Thanks. The latest patch looks good. +1 to commit.
(Minor nit: The latest patch changed the indentation for most of the new code in EmbedConnection so that it uses tabs instead of spaces. In that process some existing space-indented code in clearLOBMapping() was changed, and the javadoc for removeLobFile() was only partly changed and now has a mix of tabs and spaces.)

Thanks Knut for looking at possibilities. I am just trying to get my head around what you are suggesting. If we use the CacheManager idea would there be one cache per database or one cache per transaction? How would that fit into LobStreamControl which is instantiated once for each lob?

[jira] Commented: (DERBY-3655) errror in nightly regression test:

Knut Anders Hatlen commented on DERBY-3655:
-------------------------------------------
Thanks Kathey, I think the patch is ready for commit now. For extra credit you may also fix these tiny nits:
- indentation of closing brackets in LOBStreamControl.free(), EmbedConnection.clearLOBMapping(), EmbedConnection.addLobFile()
- lines with trailing blanks added in EmbedConnection
- EmbedConnection.lobFiles could be made final now
In the latest patch, we always create a HashSet for the lob files when we create an EmbedConnection, even if the connection doesn't use lobs that overflow to disk. Most connections don't use the HashSet, so perhaps we should go back to the approach with lazy initialization used in the previous patches? In that case, we would have to synchronize on the EmbedConnection object itself, since lobFiles may be null. If we think this is a good idea, it could be changed in a followup patch.

Knut Anders Hatlen commented on DERBY-3655:
-------------------------------------------
If the finalizer calls free(), the object must have been gc'ed, so I'm not sure how anyone else could be able to call free() at the same time. Did you ever experience a NullPointerException without the synchronization?
What I think could happen which would require synchronization, is that LOBStreamControl.finalize() calls free() -> EmbedConnection.removeLOBFile() while EmbedConnection.clearLOBMapping() is iterating over lobFiles. This could cause a ConcurrentModificationException or something in EmbedConnection. To prevent this, we would have to add synchronization in EmbedConnection around the accesses to lobFiles. I don't think synchronization in LOBStreamControl would prevent it.
Another reason to synchronize accesses to EmbedConnection.lobFiles is that we could have code that did something like this:
Blob b1 = conn.createBlob();
Blob b2 = conn.createBlob();
new Thread(new BlobHandler(b1, ...)).start();
new Thread(new BlobHandler(b2, ...)).start();
In such a case, we could get calls to addLobFile/removeLobFile on the same EmbedConnection from different threads concurrently.

-------------------------------------------
Thanks, the updated patch looks good to me. Unfortunately, it doesn't apply cleanly because of a conflict with the fix for DERBY-3883.
One question that I forgot in my previous comment: Why was the synchronization added to LOBStreamControl.free()?

Knut Anders Hatlen commented on DERBY-3655:
-------------------------------------------
I found a problem in LOBStreamControl.replaceBytes() that could prevent files from being closed (DERBY-3883). I didn't see that happening in my environment when I added some println statements and ran LobStreamsTest, so it's probably unrelated, but there is a patch that you could try just in case.
