Hi,
It seems there might be a bug with the lately implemented feature - XQuery
stacktraces. This is what I caught:
Caused by: ru.ispras.sedna.driver.DriverException: SEDNA Message: ERROR
XPTY0004
It is a type error if, during the static analysis phase, an expression is
found to have a static type that is not appropriate for the context in which
the expression oc
curs, or during the dynamic evaluation phase, the dynamic type of a value
does not match a required type as specified by the matching rules in 2.5.4
SequenceType Matchi
ng.
Details: Error in function call. Return value does not match the required
type. Expected type is [element(value-proposition)?], more than one item is
given.
Stack trace:
vp:getValuePropositionMap at 32:61
rdfutil:getURI at 32:61
documentsRdf:getLangSpecURI at 25:3
dita-value-proposition2rdf:getVpInformationElement at 38:52
dita-value-proposition2rdf:fromFilesRaw at 32:10
rdfutil:wrapRDF at 190:19
dita-value-proposition2rdf:fromFiles at 190:3
dita-value-proposition...mAllDitaValuePropositions at 195:3
(main module) at 2:1
However, vp:getValuePropositionMap is not called from rdfutil:getURI. This
is how the stacktrace should look:
Stack trace:
vp:getValuePropositionMap at 32:61
dita-value-proposition2rdf:fromFilesRaw at 32:10
dita-value-proposition2rdf:fromFiles at 190:3
dita-value-proposition...mAllDitaValuePropositions at 195:3
(main module) at 2:1
So there are simply excessive calls shown that should not be there.
Moreover, I even guess what is the root cause. It may be because I use
chained function calls:
dita-value-proposition2rdf:getVpInformationElement(vp:getValuePropositionMap
($vpId))
and
rdfutil:wrapRDF(dita-value-proposition2rdf:fromFilesRaw($files))
As a result, Sedna probably tries to pass already incorrect parameters
further to outer functions and they occasionally fail too. Then Sedna adds
all those failed functions to the stacktrace although only inner ones
actually caused that XQuery to fail. Hopefully, it'll be easy to fix.
Best regards,
Ivan Lagunov
