      Description

      During my experiments and tests of removing one-level and sub-level indices at least one integration test "SearchAuthorizationIT" failed (the test fails recursivelyDelete()). A debugging session showed that the follwing:

      • in recursivelyDelete() multiple search requests are done which leads to multiple open cursors in the XDBM search engine
      • an entry is deleted
      • when the open cursors are advanced wrong/unexpected entries are returned

      I was able to create a small test that shows the problem:

      • the index contains six tuples:
        (a,1)
        (b,2)
        (c,3)
        (d,4)
        (e,5)
        (f,6)
      • a cursor over the index is created and advanced two times, the expected tuples (a,1) and (b,2) were returned
      • now tuple (c,3) is deleted
      • when the cursor is advanced again the tuple (b,2) is returned again! I had expected (d,4).

      Note that this doesn't happen with AvlIndex.
