Thanks for the details. Very helpful.
Given it is more one dataset being written at the same time, I can now see how
it can go wrong. Your fix is good, having the call to {{encodeStore}} from
{{NodeTableNative}} provide a workspace ByteBuffer, per dataset, is also
possible.
TDB2 is not affected by this.

All accesses are inside transactions.
I'm not seeing any warnings from ds.close() but I'll keep an eye out for them.
I have 3 tdb datasets in different locations. All 3 are used in the same manner
as above where there's only 1 writer thread per dataset but multiple readers.

Andy Seaborne commented on JENA-1581:
-
If all accesses are inside transactions, then yes that's right.
There is no need to close the dataset at {{ds.close}} - do you get occasional
warnings from this call?
Accessing the base dataset is a bad idea. There is no need to release the
dataset before exit. In fact, there io no need to access {{StoreConnection}} -
{{TDBFactory}} is enough.
There is no need to {{TDBFactory.createDataset}} each time if you want to keep
it stored somewhere that's fine (internally, {{StoreConnection}} is used by
{{TDBFactory}} and has a cache anyway).
{{NodeLib.encodeStore}} is only accessed in a single threaded fashion (see the
comments for who locks it) because there is only one true writer at a time.
Do you have more than one dataset (by location) or possibly have different
names for the same location?

Scott Patterson commented on JENA-1581:

I will try to put together a small example to reproduce this.
In the meantime I tested out a small change to
org.apache.jena.tdb.lib.NodeLib.encodeStore() to always allocate a new buffer
and the problem went away. Could this be a problem with NodeLib using a
bytebuffer in a single threaded fashion?
{code:java}
//throw BufferOverflowException
final private static ByteBuffer workspace = ByteBuffer.allocate(SIZE);
public static long encodeStore(Node node, ObjectFile file) {
int maxSize = nodec.maxSize(node);
ByteBuffer bb = workspace;
if ( maxSize >= SIZE )
// Large object. Special buffer.
bb = ByteBuffer.allocate(maxSize);
else
bb.clear();
int len = nodec.encode(node, bb, null);
long x = file.write(bb);
return x;
}
//no problem
public static long encodeStore(Node node, ObjectFile file) {
int maxSize = nodec.maxSize(node);
ByteBuffer bb = ByteBuffer.allocate(maxSize);
int len = nodec.encode(node, bb, null);
long x = file.write(bb);
return x;
}
{code}
But that also made me wonder if my application is not using the api in a thread
safe manner.
Upon startup my application does:
{code:java}
String directory = "/path/to/tdb";
StoreConnection storeConn = StoreConnection.make(directory);
{code}
And during shutdown it does
{code:java}
storeConn.getBaseDataset().close();
StoreConnection.release(Location.create(directory));{code}
While the application is running I only create 1 writer thread at a time and it
is using the TDB like this:
{code:java}
Dataset ds = TDBFactory.createDataset(directory);
try {
ds.begin(ReadWrite.WRITE);
try {
//add graphs
} finally {
ds.end();
}
} finally {
ds.close();
}{code}
but the application may have at least two other reading threads using the TDB
like this:
{code:java}
Dataset ds = TDBFactory.createDataset(directory);
try {
ds.begin(ReadWrite.READ);
try {
//
} finally {
ds.end();
}
} finally {
ds.close();
}
{code}
Is this usage correct? I'm wondering if the reason the NodeLib is tripping up
is because multiple threads are using the private static ByteBuffer.
