[jira] [Created] (JENA-869) Fuseki2: Can't reuse dataset name after
DELETE
Stian Soiland-Reyes created JENA-869:
----------------------------------------
Summary: Fuseki2: Can't reuse dataset name after DELETE
Key: JENA-869
URL: https://issues.apache.org/jira/browse/JENA-869
Project: Apache Jena
Issue Type: Bug
Components: Fuseki
Affects Versions: Fuseki 2.0.0
Environment: Docker
https://registry.hub.docker.com/u/stain/jena-fuseki/
Reporter: Stian Soiland-Reyes
Fix For: Fuseki 2.0.0
In the web interface, I create a persistent dataset "test1". I then remove it. I then create a second one called "test1". Everything works fine.
However, if I restart Fuseki, now it attemps to register test1 twice:

Notice that 409.. the web UI didn't indicate anything about this.
Inspecting my /fuseki reveals indeed that test1 appears three times:
root@35e5b435426c:/fuseki# grep -r test1 .
Binary file ./system/nodes.dat matches
./system_files/f9508798-2ac1-11b2-80c2-dab7e13f8f6e: rdfs:label "TDB test1" ;
./system_files/f9508798-2ac1-11b2-80c2-dab7e13f8f6e: fuseki:name "test1" ;

f950879c-2ac1-11b2-80c2-dab7e13f8f6e is not in ./system/prefixes.dat and ./system/nodes.dat, while the other two UUIDs are.
