[Exist-open] xmldb:rename shows incorrect behaviour on collections with subcollections (eXist 5.2)

[Jo C. <Jo....@ha...>]

Hi all,

The following query produces no output

xquery version "3.1";
declare variable $collection-1-name := util:uuid();
declare variable $collection-2-name := util:uuid();
declare variable $collection-1-uri := "/db/" || $collection-1-name;
declare variable $sub-collection-name := "subcollection";
declare variable $sub-collection-uri := $collection-1-uri || "/" ||
$sub-collection-name;
declare variable $collection-2-uri := "/db/" || $collection-2-name;
declare variable $expected-sub-collection-uri :=  $collection-2-uri || "/"
|| $sub-collection-name;
declare variable $resource-name := "test.xml";

declare function local:test() {
    xmldb:create-collection("/db",  $collection-1-name),
    xmldb:create-collection($collection-1-uri,  $sub-collection-name),
    xmldb:store($sub-collection-uri, $resource-name, <test/>),
    xmldb:rename($collection-1-uri, $collection-2-name),
    xmldb:collection-available($expected-sub-collection-uri)
};

local:test()

Furthermore, attempts to delete the resulting  $collection-2-uri via eXide
> Manage gives a dialog "Delete Resource Error".   The following is shown
in exist.log:
