tdb_transaction_cancel

[Taj Khattra]

take two...

here's a contrived test case.  it aborts with the latest tdb in svn,
but works ok with the tdb in samba4-tp4.

could someone please confirm if this is a bug, or a
misunderstanding/misuse of the tdb api on my part?

thanks.

        TDB_DATA key = {"hi", 2};
        tdb_transaction_start(tdb);
        assert(tdb_chainlock(tdb, key) == 0);
        tdb_transaction_cancel(tdb);                    /* should
release all locks??? */
        assert(tdb_chainunlock(tdb, key) == -1);
