[jira] [Updated] (JENA-158) QueryCancelledException not being
caught in Fuseki
[ https://issues.apache.org/jira/browse/JENA-158?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Alexander Dutton updated JENA-158:
----------------------------------
Attachment: jena-158.diff
Improves Fuseki to return a 503 with a friendlier error message on timeout.
NB. My CCLA is pending sign-off from the PTB at OUCS. The license grant is conditional on my CCLA getting the go-ahead.

> [This is a reformulation of http://mail-archives.apache.org/mod_mbox/incubator-jena-dev/201111.mbox/%3C4EBAA0A3.8%40oucs.ox.ac.uk%3E and following messages]
> When a query times out the client currently receives the following, which doesn't explain much:
> > Error 500: Server Error
> This is the result of a QueryCancelledException being caught at line 107 of SPARQL_ServletBase, which has the comment "This should not happen"
> It'd be good if this were explicitly caught and a more user-friendly error message provided.
> I don't know what HTTP status code should be provided; the SPARQL spec says 500, but that upsets me (and Hugh Glaser)¹. Andy points out that it should be a 5xx status code². I've started a thread on ietf-http-wg asking for something along the lines of a "Request Too Onerous" status code.³
