Rupert Westenthaler commented on STANBOL-877:
---------------------------------------------
Based on mail [1] from Gintautas Sulskus I noticed that this was never applied
to the code base. I will check if [1] is really caused by this and apply the
patch if it was not done yet.

> Double quote in query text cause sparql query to fail
> -----------------------------------------------------
>
> Key: STANBOL-877
> URL: https://issues.apache.org/jira/browse/STANBOL-877
> Project: Stanbol
> Issue Type: Bug
> Components: Entityhub
> Reporter: Florent ANDRE
> Assignee: Rupert Westenthaler
> Attachments: SPARQL-grammar-escapes-STANBOL-877_rw.patch,
> escape-quote-877.patch
>
>
> With the use of NLP engines and some content with quoted text inside, quotes
> can be in the string searched by the entityhub.
> Associated with a RDF store, the generated sparql query is not legal as the
> double quote is not escaped.
> Patch submitted as I'm actually stick to rev 1420034.
> This patch contains :
> * A unit test at the
> query/clerezza/src/test/java/org/apache/stanbol/entityhub/query/clerezza/SparqlQueryUtilsTest.java
> level
> * A quote escape in
> generic/servicesapi/src/main/java/org/apache/stanbol/entityhub/servicesapi/query/TextConstraint.java
> for escaping in all query generation cases
> * a remove in
> generic/servicesapi/src/main/java/org/apache/stanbol/entityhub/servicesapi/util/PatternUtils.java
> as this double escape something already escaped that lead to not still
> escape the characters during regex part generation.
> All the project compile with this patch at this rev.
