(me again ;-) I'm still "toying" with the ODMG implementation and I
stumbled upon something strange (at least in my eyes). While working
through the ODMG testcases, I noticed that when I change the
PersonWithArrayTest.testStoreThreePersons test a slightly bit from
Transaction tx = odmg.newTransaction();
tx.begin();
tx.lock(karlHeinz, Transaction.WRITE);
tx.lock(kurt, Transaction.WRITE);
tx.lock(knuth, Transaction.WRITE);
tx.commit();
to
Transaction tx = odmg.newTransaction();
tx.begin();
tx.lock(kurt, Transaction.WRITE);
tx.lock(knuth, Transaction.WRITE);
tx.lock(karlHeinz, Transaction.WRITE);
tx.commit();
or also to
Transaction tx = odmg.newTransaction();
tx.begin();
tx.lock(kurt, Transaction.WRITE);
tx.lock(knuth, Transaction.WRITE);
tx.commit();
tx.begin();
tx.lock(karlHeinz, Transaction.WRITE);
tx.commit();
then in both cases the test fails (the collection was not stored
correctly).
Is there a reason that I have to put the objects in exactly this order
(see first change) and that I have to lock the subobjects in the same
transaction (see second change) ?
Thanks,
Tom
