Update of /cvsroot/monetdb/pathfinder/runtime
In directory sc8-pr-cvs16.sourceforge.net:/tmp/cvs-serv7520
Modified Files:
Tag: XQuery_0-18
pathfinder.mx
Log Message:
(Jennie on behalf of Peter)
- bugfix in index-destroy when a document is added to a read-only
collection. this corrupted the index structure, leading
to some fine 'runtime fetch index 12 not found' errors later on.
BTW: under such loads (read-only queries, interleaved with add-docs)
it is thus better to declare the collection as updatable,
because updatable indices are maintained, rather than
thrown away on each add-doc (read-only policy).
(question is whether TIJAH will choke on the NIL nodes
that occur in the updatable document representation)
