Update of /cvsroot/monetdb/pathfinder/compiler/core
In directory sc8-pr-cvs7.sourceforge.net:/tmp/cvs-serv29175/compiler/core
Modified Files:
Tag: XQuery_0-16
fs.brg
Log Message:
- fn:collection() and pf:collection() are not considered information
functions anymore (less locking)
- pf:collection() had forgotten to pin the opened collection
- fn:collections() and pf:documents() do not return names of cached documents,
only of explicitly shredded docuyments
- let updating functions be more lenient with target nodes
(embed exactly-one to do runtime checking)
