Summary: CMDleftfetchjoin: operation failed

Initial Comment:
The query below (which uses the attached module) results in an error.

import module namespace pxml = "http://www.cs.utwente.nl/~keulen";
   at "/local/keulen/Programming/probprot/monetdb/probxml.xq";

let $imovie1 := <movie>
                   <title>King Kong</title>
                   <year>2005</year>
                </movie>
   ,$imovie2 := <movie>
                   <title>King Kong</title>
                   <year>1933</year>
                </movie>
   ,$config := <config>
                  <nonmultiple>title</nonmultiple>
                  <nonmultiple>year</nonmultiple>
               </config>
return
let $i := pxml:integrate_e($config,$imovie1,$imovie2)
return
<a>{$i}
</a>

I just made rigorous changes to the code in the module, so I can't tell you 
what the output of the query should be. It should in any case not be a MonetDB 
error message.

ERROR = !ERROR: BATmalleftfetchjoin: Cannot perform leftfetchjoin: right head 
is no dense OID column.
        !ERROR: CMDleftfetchjoin: operation failed.

Version: Just compiled the latest HEAD-version (today 5 feb). Suse/Linux.

1)
renamed test "ID.165527.*" to "ID.1652527.*" in
pathfinder/tests/BugsViaSourgeforce/Tests/;
the latter is the correct bug ID and (correctly) listed in the "All",
i.e., as testing, Mtest, the TestWeb told/tell us,
this new test was thus never executed...

2)
back-ported new tests "ID.1652527.*" & "ID.1648854.*"
in pathfinder/tests/BugsViaSourgeforce/Tests/
from the development trunk to the XQuery_0-16 release branch;

since the bugs were (correctly) fixed in the XQuery_0-16 release branch,
also the repective tests should be added there to confirm and monitor the
fix.

with "Mserver --debug=10" it produces:

!= 10=|l|) => can't use fetchjoin.

Maurice,

(as usually with such property related problems)
to help locating the problem, could you please try what the result/effect
is if you run Mserver with --debug=10 (i.e., property checking enabled)?
Thanks in advance!

Stefan
