Summary: XQuery: collection management broken
Initial Comment:
Today's MonetDB 4.17
Given a small document: <aap id="1"/>
shredding it once, deleting it, and shredding it again corrupts the database.
[wou...@localhost test]$
/opt/MonetDB-4.17/bin/MapiClient -lxq -p50170
xquery>pf:add-doc("/home/wouter/test.xml","doc1.xml")
more>xquery>pf:del-doc("doc1.xml")
more>xquery>pf:add-doc("/home/wouter/test.xml","doc1.xml")
more>xquery>pf:collection("doc1.xml")
more><aap id="1"/><aap id="1"/>
xquery>
At first sight the document still looks intact:
xquery>doc("doc1.xml")
more><?xml version="1.0" encoding="utf-8"?>
<aap id="1"/>
But then it looks like the document's document node has gone, because:
xquery>doc("doc1.xml")/aap
more>
xquery>
gives an empty result.

yes indeed, it seems that:
- pf:del-doc() does not cleanup empty-collections, while MIL delete_doc()
does this
as a result, the second add-doc adds the document to the previous
collection
- there seems to be a bug in index filtering for deleted documents in a
multi-doc collection
as the functinality is new, so it is not that surprising
will fix soon
