[jira] Closed: (DIRSERVER-759) object scope search on non-existant DN gives IllegalArgumentException: "Argument 'an_obj1' is null"

Emmanuel Lecharny closed DIRSERVER-759.
---------------------------------------

    Resolution: Cannot Reproduce

Well, I have added some test case for this issue, but it seems I cannot reproduce the problem.

The committed test cases are : http://svn.apache.org/viewvc?view=rev&rev=496459

I close the issue, if another test case can reproduce the problem, we will reopen it.

> Fire up a vanilla empty ApacheDS 1.1 instance, and then attempt an object scope search on a non-existant base DN like "cn=admin,ou=system", with filter "(objectclass=*)" returning no attributes. 
> Instead of a NameNotFoundException exception you get the following stack trace:

> The problem seems to be that in the enumerate method in ScopeEnumerator.java:67, the following line returns null:
>         final BigInteger id = db.getEntryId( snode.getBaseDn() );
> but nonetheless a IndexRecord is created and returned anyway. I don't know this code well enough to be certain whether a "LdapNameNotFoundException" should be thrown at this stage, or whether instead a check for a null IndexRecord id should be performed later when actually evaluating the filter. If someone more knowledgeable can offer some advice on this point then I can submit a patch and testcase.
> Note I tested if the same problem occurs in 1.0, and it doesn't.
