------------------------------
> TDB corruption
> --------------
>
> Key: JENA-342
> URL: https://issues.apache.org/jira/browse/JENA-342
> Project: Apache Jena
> Issue Type: Bug
> Components: Fuseki
> Affects Versions: Fuseki 0.2.4
> Environment: Windows 7 Professional x64, Oracle Java 1.7.0_07, Fuseki
> script executed in Cygwin
> Reporter: Simon Burrows
> Assignee: Andy Seaborne
> Fix For: Fuseki 0.2.5
>
> Attachments: after_restart.txt, anon_database.zip,
> anonymized_current.ttl, anonymized_prior.ttl, config-anon.ttl, first.txt,
> fuseki-log, second.txt
>
>
> It seems that the TDB can corrupt data (especially blank nodes) after certain
> data is uploaded.
> To replicate this issue, follow these steps:
> 1. Start Fuseki with the supplied "config-anon.ttl" configuration.
> 2. Upload "anonymized_prior.ttl" via the web interface.
> 3. Upload "anonymized_current.ttl" via the web interface.
> 3a. Executing "SELECT ?s ?p ?o WHERE { ?s ?p ?o }" should return content as
> per "second.txt".
> 4. CTRL-C the Fuseki server.
> 5. Restart the Fuseki server.
> 6. Executing "SELECT ?s ?p ?o WHERE { ?s ?p ?o }" should now return content
> as per "after_restart.txt".
> Notes:
> * I think executing the SELECT between the uploads of the file prevented the
> problem, but I'm not able to reproduce that reliably.
> * If further data is uploaded before the CTRL-C the problem will not occur.
