Hi all,
playing with GeoServer's REST API I experienced a behavior that doesn't
sound right, at least to me.
When a namespace is created issuing a POST request to the /namespaces
endpoint, a corresponding workspace is automatically created by
GeoServer; conversely, when a namespace is deleted issuing a DELETE
request to the /namespaces/<ns> endpoint, the associated workspace is
not explictly removed from the catalog (I checked the code in
NamespaceResource) and continues to appear in the UI (a
NullPointerException is thrown if user clicks on it) and in the outcome
of REST calls, even though the workspace.xml file no longer exists on
disk. If GeoServer is rebooted, the workspace disappears.
I believe this could be fixed either by adding a few lines of code to
NamespaceResource's method:
https://github.com/geoserver/geoserver/blob/d54d57219141b9d8806307c1f02228c0008912c4/src/restconfig/src/main/java/org/geoserver/catalog/rest/NamespaceResource.java#L109
or, more generally, by implementing the method
handleRemoveEvent(CatalogRemoveEvent) in the catalog listener
NamespaceWorkspaceConsistencyListener:
https://github.com/geoserver/geoserver/blob/d54d57219141b9d8806307c1f02228c0008912c4/src/main/src/main/java/org/geoserver/catalog/NamespaceWorkspaceConsistencyListener.java#L128
cURL requests to reproduce the issue:
curl -X POST -d
'<namespace><prefix>test_ns</prefix><uri>http://www.exmple.com</uri></namespace>'
-H "Content-Type: text/xml" -u admin:geoserver
http://localhost:8080/geoserver/rest/namespaces
curl -X DELETE -u admin:geoserver
http://localhost:8080/geoserver/rest/namespaces/test_ns
I'm using GeoServer master.
