Floris, I personally consider this a bug, so please go ahead and file a but report about it --- in any case, bug reports make dealing with, tracing and monitoring of problems much more convenient. Thanks you very much! Stefan On Wed, Dec 03, 2008 at 12:39:13PM +0100, Floris Ouwendijk (DT) wrote:

Dear users,

While investigating a problem where a collection-query returns invalid data, I ran into problems with mclient seemingly not generating a proper exit value.

If I run: $ mclient -lxq -p49980 -s"element { \"log\" } { pf:collection(\"cons02_log.xml\")//run }" -removed a lot of xml- </stdout>

The above returns a lot of correct XML, then dumps an error to stderr, but returns error code 0. In contrast, the following works as expected:

$ mclient -lxq -p49980 -s"eelement { \"log\" } { pf:collection(\"cons02_log.xml\")//run }" >/dev/null MAPI = monetdb@server:49980 QUERY = eelement { "log" } { pf:collection("cons02_log.xml")//run } ERROR = !parse error: syntax error, unexpected {, expecting $end on line 1, column 10 (next token is `{') !parse error: XQuery parsing failed !# halted in parser.tab.c (PFparse), line 5716 $ echo $? 1

Which is the expected result for a flawed query.

Do you agree this is a problem that should be reported, or is there a better way of finding out whether there were problems running the query?

Kind regards,

Floris
