Steven Hawkins commented on TEIID-2068:
---------------------------------------

There are several issues here.
1. Is there a valid recursion limit for the test?  Since the code and unit tests have not changed, I would re-verify the test scenario by manually inspecting if the recursion depth is actually 3.
2. RECORD was never implemented - see https://issues.jboss.org/browse/TEIID-63 back when were more intent on retiring the XML document model feature we didn't see a need to add support.  I'm not sure exactly what this was supposed to do.  I had just assumed there would be a log entry if the recursion limit was exceeded.
3. If RECORD is set rather than THROW, then it seems like you just keep recusing (related to 1).  I would expect here that the limit is still respected.  I believe this is an issue with the logic in RecuseProgramCondition which could be addressed easily (and a log could be added to address 2).
The record feature was never implemented.  I'm assuming that it means produce a log

> I ran the E2ERecursiveXmlTextSource test. It involves setting a limit of 3 on the recursion, and then changing the limit to 4 (where all XML document queries will pass). I found the limit exception was being thrown regardless of the setting (even up to 10).
> I changed the behavior from THROW to RECORD and now the queries do not return (in a timely manner), leading me to worry that recursion may be the cause, not the limit itself.
> Model Project Set and server log will be attached.
> Just looked at the command log and it looks pretty weird. I'd be inclined to start there. I AM able to successfully query the source (text).
